The above technical scheme of this application has following beneficial effect:

1. in this application, through add the limit structure who is used for spacing extrusion chamber of axial and die head support on wheaten food machine for extrusion chamber and die head support are unable axial displacement under the condition of not unblock, have avoided the die head support slippage to drop from the extrusion chamber promptly. On this basis, still set up limit structure including spacing portion and with spacing portion complex cooperation portion, set up spacing portion on one of them of extrusion chamber and die head support, set up the cooperation portion on another for it is spacing that extrusion chamber and die head support both can realize the axial through the cooperation of spacing portion with the cooperation portion. The extrusion cavity and the die head cover of the existing wheaten food machine are not provided with an axial limiting structure, so that a user can easily loosen or pop up when only installing the die head support in the extrusion cavity, and the extrusion cavity and the die head support can be locked only by equipping the die head cover. In the scheme, axial limiting can be realized only by matching the extrusion cavity with the die head bracket, so that a die head cover can be omitted, and the cost of the whole machine is reduced; on the other hand, it is spacing that extrusion chamber and die head support pass through the axial that cooperation portion and installation department realized, can prevent effectively that the die head support from extruding the chamber slippage and going out, avoids taking place the safety problem. In addition, the reduction of accessories reduces the complexity and the trouble of installation of a user, thereby improving the assembling experience of the user.

2. In order to prevent the safety problem that a user is accidentally injured due to the fact that the extrusion screw rod is exposed when the user does not install the die head support and the wheaten food machine is started by mistake, the elastic piece for axially pressing the extrusion screw rod is arranged in the wheaten food machine. However, the resilient member is configured such that when the user merely installs the die holder, the resilient member directly or indirectly pushes the extrusion screw outwardly, which in turn axially ejects the die holder, causing the die holder to slip off of the extrusion chamber. According to the existing noodle maker, a user needs to press the die head support inwards in the axial direction by one hand, and the die head cover is installed by the other hand, so that the installation is complex, and the user experience is poor. Therefore, the scheme also provides that when and only when the die head support is installed in place, the elastic piece is in an extruded state, and the die head support is axially clamped with the matching part through the limiting part to realize axial limiting of the extrusion cavity. Because the die head bracket and the extrusion cavity can realize axial spacing under the condition of not needing a die head cover, and the spacing part and the matching part are clamped when the die head bracket and the extrusion cavity are arranged. That is to say, the user can be one hand with die head support axial install to the extrusion chamber inwards can realize that spacing portion is the joint with cooperation portion, need not to carry out follow-up or install the process of die head lid simultaneously to realize the one-hand installation, promote the installation of wheaten food machine greatly and experience the sense. Certainly, in order to further ensure the axial installation stability of the die head support and the matching part, a die head support can be sleeved at the joint of the die head support and the extrusion cavity for further fastening, and at the moment, the user can also realize one-hand installation.

3. Set up the first convex part that the cooperation portion was established for radially protruding along extrusion chamber lateral wall in this scheme, first convex part be used for with spacing portion axial on the die head support form the axial spacing, realize the axial fixity in die head support and extrusion chamber to prevent that the die head support from droing.

4. In order to ensure high visibility of the first protrusion to a user, the first protrusion is further provided to protrude radially outward along the outer side wall of the pressing chamber. Meanwhile, in order to ensure the axial fixing reliability of the first convex part and the limiting part and enhance the strength of the first convex part, the first convex part is arranged to extend along the circumferential direction of the extrusion cavity. Otherwise, the first convex part is only axially long and circumferentially short, after the first convex part is matched with the limiting part, the overlapping area of the first convex part and the limiting part along the axial direction is small, and the first convex part and the limiting part are easy to separate from the axial direction for limiting.

5. In order to realize user's blind dress, promote the installation and experience the sense, still set up spacing portion including being used for guiding the guide way that cooperation portion axial was inserted. Due to the arrangement of the guide groove, a user only needs to make the die head support slightly rotate back and forth in the circumferential direction opposite to the front end of the extrusion cavity, and the matching part can be smoothly clamped into the guide groove. After entering the guide way, in order to realize the axial locking of cooperation portion and location portion, still set up spacing portion including with the guide way intercommunication be used for cooperation portion circumferential direction's swivelling chute and locate the second convex part of guide way and swivelling chute internal corner, the second convex part is relative the guide way with the swivelling chute is protruding to be established. Therefore, after the die head support is clamped into the guide groove, the user rotates in the circumferential direction for a certain angle, and the matching part rotates to the position in axial alignment with the second convex part along the rotating groove. That is to say, when the cooperation portion rotated to the right, the cooperation portion and second convex part formed the axial spacing, guaranteed the reliability of both axial spacing.

6. Because this scheme is directly installed through die head support and extrusion chamber, has cancelled current die head lid structure. Therefore, under the condition that the die head cover is not installed, the extrusion screw rod rotates forwards and backwards in the processing process of the wheaten food machine, and the rotation acting force of the food material on the die head support is opposite to the rotation direction of the die head support when the die head support is installed in the extrusion cavity in one steering process, so that the die head support rotates backwards to fall off, and even the die head support is thrown out to hurt a user. For solving the safety problem that this die head support is reverse to be unscrewed and drop or even injure the user by mistake, set up in this scheme cooperation portion for following the radial protruding first convex part of establishing of extrusion chamber lateral wall, the second convex part with one side of swivelling chute intercommunication is equipped with the groove of splining, be equipped with the protruding muscle of splining on the first convex part. The stop-rotating convex ribs are clamped into the stop-rotating grooves, the stop-rotating convex ribs and the stop-rotating grooves are circumferentially interacted, circumferential positioning of the matching portion and the positioning portion is formed, and the die head support is greatly reduced to reversely screw out and drop or even injure a user by mistake.

7. In order to ensure that the matching part is rotated into the rotating groove and axially limited by the second convex part, the matching part and the second convex part are axially limited and more reliable, the phenomenon that the matching part and the second convex part slip can be avoided, the rotating angle is relatively small when a user installs the die head support and the experience feeling is not influenced, the length of the second convex part along the circumferential direction of the extrusion cavity or the circumferential direction of the die head support is set to be L, and L is more than or equal to 2mm and less than or equal to 40 mm. When L is less than 2mm, the circumferential length of the matching part and the second convex part is too narrow, so that the matching part and the second convex part are easy to slip and fall off; when L is greater than 40mm, because the circumference length of cooperation portion and second convex part complex is too wide, lead to the user to rotate great angle just can with die head support mounting on the extrusion chamber, seriously influence the user and use experience.

8. Because the installation of current extrusion chamber and die head support all is the mode of establishing each other cover, consequently, also can be through setting up the cooperation portion into the edge the radial protruding first convex part of establishing of die head support lateral wall, spacing portion is located on the lateral wall in extrusion chamber, spacing portion including be used for guiding first convex part axial male guide way, with the guide way intercommunication be used for first convex part circumferential direction's swivelling chute and locate the second convex part of guide way and swivelling chute internal corner, the second convex part is relative the guide way with the swivelling chute is protruding to be established the cooperation portion is rotatory when arriving the position, first convex part forms the axial spacing with the second convex part. When the die head support is installed, a user only needs to enter the first convex part on the die head support into the rotating groove through the guide groove, and then the first convex part and the second convex part are axially clamped along the rotating groove at a certain rotating angle, so that the die head support and the extrusion cavity can be installed. The scheme has simple structure and is convenient for the user to operate.

9. Locate through setting up the die head support cover the extrusion chamber outside, the cooperation portion is for following the protruding first convex part of establishing of extrusion chamber lateral wall, spacing portion is for the axial guide way of locating the die head support inside wall for cooperation portion and spacing portion are located the space of establishing formation with the die head support cover in the extrusion chamber. Therefore, when the die head bracket and the extrusion cavity are installed in place, the matching part and the limiting part cannot be exposed to influence the attractiveness. On the basis, in order to prevent the die head support from slipping out of the extrusion cavity, the axial friction force between the first convex part and the guide groove is relatively increased by setting the radial clearance delta X between the first convex part and the guide groove to be more than or equal to 0mm and less than or equal to 0.2 mm. When Δ X is smaller than 0mm, the gap between the first protrusion and the guide groove is too small, which may make it difficult to mount and dismount the die holder to and from the extrusion chamber, thereby affecting the user experience. When the delta X is larger than 0.2mm, because the clearance between the first convex part and the guide groove is too large, the axial friction force between the first convex part and the guide groove is greatly reduced, the die head support is not enough to be supported, and the die head support is very easy to drop. Particularly, when the elastic part is additionally arranged in the pasta machine, the elastic part directly or indirectly axially pushes the extrusion screw, the extrusion screw exerts ejection elastic force like a die head bracket, and at the moment, the radial gap delta X between the first convex part and the guide groove is more required to be ensured to be between 0mm and 0.2 mm.

10. In order to prevent the safety problem that a user is accidentally injured due to the fact that the extrusion screw rod is exposed when the user does not install the die head support and the wheaten food machine is started by mistake, the elastic piece for axially pressing the extrusion screw rod is arranged in the wheaten food machine. On the basis, in order to simplify the specific structures of the limiting part and the matching part and have installation guidance for users, the limiting part and the matching part are also provided with magnetic pieces with opposite magnetism and larger attraction force than the elastic force of the elastic piece. Like this, because the suction user of magnetic part will attract the die head support to extrude on the chamber and counterpoint the accuracy when being close to the extrusion chamber gradually, the user just once only can be with die head support installation to extrusion chamber on. And in order to prevent the elastic force of the elastic piece from ejecting the die head bracket axially, the suction force between the magnetic limiting part and the magnetic matching part is also set to be larger than the elastic force of the elastic piece.

It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The present invention will be described in further detail with reference to the following drawings and specific examples.

The utility model provides a wheaten food machine, as shown in figures 1 to 5, the wheaten food machine comprises a machine base 1 internally provided with a motor and a processing cavity 2 arranged on the machine base 1, the processing cavity 2 comprises a dough kneading cavity 21 and an extrusion cavity 22 which are communicated with each other, a stirring rod 211 is arranged in the dough kneading cavity, and an extrusion screw 221 is arranged in the extrusion cavity 22. The front end of the extrusion cavity 22 is provided with a die head component 3, and the die head component 3 is provided with a face outlet. The die assembly 3 includes at least a die holder 33 and a die 331 with an exit aperture.

In the present application, whether the extrusion screw is disposed vertically or horizontally, and whether the stirring rod is disposed vertically or horizontally, are not particularly limited. Whether the die 331 and the die holder 331 are integrally connected or separately connected, and whether the lower face or the front face is exposed, are not particularly limited.

Typically, the user will install the stirring rod 211 in the dough mixing chamber 21, the extrusion screw 221 in the extrusion chamber, and the die assembly. After the assembly is completed, the user can place dry flour into the dough kneading cavity 21, then the cup cover at the upper end of the dough kneading cavity 21 is closed, and the machine base can automatically feed water or the user manually feeds water to knead dough. After kneading, the small flocks or small dough enter the extrusion chamber 22, and the rotation of the extrusion screw 221 pushes the small flocks or small dough toward the die holder 31, and noodles are formed from the outlet hole.

Specifically, as shown in fig. 2 to 11, the pasta machine of the present application includes a limiting structure for axially limiting the extrusion chamber and the die holder, so that the extrusion chamber 22 and the die holder 33 cannot axially move without being unlocked, i.e., the die holder is prevented from slipping off the extrusion chamber 33 and falling off. On this basis, still set up limit structure in this application include spacing portion and with spacing portion complex cooperation portion sets up spacing portion on one of them of extrusion chamber and die head support 33, sets up the cooperation portion on another for it is spacing that both can realize the axial through spacing portion and cooperation portion's cooperation in extrusion chamber and the die head support. The limiting structure described in the present application is not a die cover in the prior art. The extrusion cavity and the die head cover of the existing wheaten food machine are not provided with an axial limiting structure, so that a user can easily loosen or pop up when only installing the die head support in the extrusion cavity, and the extrusion cavity and the die head support can be locked only by equipping the die head cover.

In the scheme, axial limiting can be realized only by matching the extrusion cavity 22 with the die head bracket 31, so that a die head cover can be omitted, and the cost of the whole machine is reduced; on the other hand, extrude chamber 22 and die head support 31 through the axial spacing that cooperation portion and installation department realized, can prevent effectively that die head support 31 from extruding chamber 22 slippage and going out, avoid taking place the safety problem. In addition, the reduction of accessories reduces the complexity and the trouble of installation of a user, thereby improving the assembling experience of the user.

In some embodiments of the present application, as shown in fig. 2, a horizontal noodle maker in which the stirring bar 211 and the extrusion screw 221 are coaxial and horizontal is exemplified. An elastic member 4 for axially biasing the extrusion screw is further provided between the agitating bar 211 and the extrusion screw 221. The elastic member 4 is used for preventing the safety problem that the user is accidentally injured due to the exposure of the extrusion screw 221 when the user mistakenly starts the pasta machine without installing the die head bracket 31.

However, the arrangement of the elastic member 4 is such that when the user merely mounts the die holder, the elastic member 4 directly or indirectly pushes the extrusion screw 221 outward, and the extrusion screw 221 in turn axially ejects the die holder 31, causing the die holder 31 to slip off the extrusion chamber 22. The user needs a hand to press the die head support inwards in the axial direction, and the other hand is used for installing the die head cover, so that the installation is complex, and the user experience is poor. For solving the poor problem of user's installation experience sense, this embodiment still sets up if and only when the die head support mounting target in place, and elastic component 4 is in by the extruded state, die head support 31 through spacing portion with the cooperation portion axial joint realize with extrude the axial in chamber spacing. That is to say, the user can be singlehanded with die head support 31 axial installation inwards to extrude on the chamber 22 can realize the joint of spacing portion and cooperation portion, if be equipped with the die head lid, also can singlehanded reinstallate the die head lid, need not one hand and pushes up the die head support, install the die head lid on the other hand.

It can be understood that under the more preferred embodiment, as shown in fig. 4, when the axial positioning of the extrusion cylinder 22 and the die head bracket 31 can be satisfied through the axial clamping of the matching part and the mounting part, the die head cover does not need to be equipped, the subsequent or simultaneous process of mounting the die head cover is omitted, the cost is saved, the one-hand mounting is realized, and the mounting experience of the pasta machine is greatly improved.

It will also be appreciated that in another embodiment, instead of providing the elastic element for ejecting the extrusion screw inside the pasta machine, only the aforementioned axial stop structure may be provided.

The elastic member 4 in the present embodiment is a spring, but may be replaced with a material having elasticity such as an elastic sheet. In addition, the specific position of the elastic member is not particularly limited in the present application, and may be located, for example, inside the driving assembly or at the end of the extrusion screw.

Specifically, for the structure of the matching portion and the mounting thereof, the present application provides several preferred embodiments below, but is not limited to the embodiments provided by the present application, and as long as the axial locking and the limiting are realized through the matching portion provided on the extrusion cylinder and the mounting portion provided on the die head bracket, or the mounting portion provided on the extrusion cylinder and the matching portion provided on the die head bracket, so as to prevent the die head bracket from axially slipping, the preferred embodiments all fall into the protection scope of the present application.

Embodiment 1: as shown in fig. 2 to 3 and 5 to 7, the fitting portion is a first protrusion 222 protruding radially outward along the outer side wall of the front end of the extrusion chamber 22, and the limiting portion is disposed on the inner wall of the die holder 31. The first protrusion is located on the outer side wall of the pressing chamber 22 to improve visibility for the user. The limiting part comprises a guide groove 313 for guiding the first convex part 222 to be inserted axially, a rotating groove 314 communicated with the guide groove 313 and used for the first convex part to rotate circumferentially, and a second convex part 312 arranged at the inner corner of the guide groove 313 and the rotating groove 314. The guide groove 313 is used for realizing blind installation of a user, and installation experience is improved. When the user fits the die holder 31 to the front end of the extrusion chamber 22, the user can smoothly snap the first protrusion 222 into the guide groove 313 by only rotating the die holder 31 slightly back and forth circumferentially against the front end of the extrusion chamber 22. The first protrusion 222 slides into the rotation groove 314 under the guidance of the guide groove 313, and then rotates along the rotation groove 314 in the circumferential direction by a certain angle to a side away from the guide groove 313. Until the first protrusion 222 is rotated into position, the first protrusion 222 and the second protrusion 312 form an axial snap lock, thereby ensuring that the die holder 31 is reliably mounted on the extrusion chamber 22, at least without axial slipping. That is, when the first protrusion 222 rotates to the position, the first protrusion 222 and the second protrusion 312 form an axial limit, so that the reliability of the axial limit of the extrusion chamber 22 and the die holder 31 is ensured.

Meanwhile, in order to ensure the reliability of the axial fixation of the first convex portion 222 and the second convex portion 312, and to enhance the strength of the first convex portion 222, the first convex portion 222 is further provided to extend in the circumferential direction of the extrusion chamber 22. Otherwise, the first protrusion 222 is only axially long and circumferentially short, and after the first protrusion 222 is matched with the second protrusion 312, the overlapping area of the first protrusion 222 and the second protrusion 312 along the axial direction is small, and the first protrusion 222 and the second protrusion 312 are easily separated from the axial limit.

It can be understood that, when the extrusion chamber 2 is sleeved outside the die holder 31, the matching portion may also be a first protrusion protruding inwards along the inner sidewall of the extrusion chamber, and the guide groove 313, the rotation groove 314, and the second protrusion 312 of the limiting portion are located on the outer sidewall of the die holder 31.

It can also be understood that, by providing the fitting portion as the first protrusion 222 protruding along the radial direction of the sidewall of the die holder 31, the limiting portion is provided on the sidewall of the extrusion chamber 22, the limiting portion includes a guide groove 313 for guiding the first protrusion 222 to be axially inserted, a rotation groove 314 communicating with the guide groove 313 for circumferential rotation of the first protrusion 222, and a second protrusion 312 provided at the inner corner of the guide groove 313 and the rotation groove 314, the second protrusion 312 protrudes from the guide groove 313 and the rotation groove 314, and when the fitting portion is rotated to the position, the first protrusion 222 and the second protrusion 312 form axial limitation. When the die head support is installed, a user only needs to enter the first protrusion 222 on the die head support 31 into the rotating groove 314 through the guide groove 313 and then rotate a certain angle along the rotating groove 314 until the first protrusion 222 and the second protrusion 312 are axially clamped, so that the die head support 31 and the extrusion cavity 22 can be installed. The scheme has simple structure and is convenient for the user to operate.

Embodiment 2: in this embodiment, a first protrusion 222 is disposed on an outer sidewall of the extrusion chamber 22 and protrudes outward in a radial direction, a second protrusion 312 is disposed on an inner sidewall of the die holder 31 and protrudes inward in a radial direction, the second protrusion 312 is protruded relative to the inner sidewall of the die holder 31, and the second protrusion 312 has an L-shaped structure. The second convex portion 312 includes a first convex edge extending along the circumferential direction of the die holder 31 and a second convex edge connected to the first convex edge and extending axially toward the die holder 31. In this case, the guide groove 313 and the rotary groove 314 structure in embodiment 1 are not required. During installation, the die holder 31 is axially clamped to the extrusion chamber 22 only when the first flange and the first protrusion are misaligned, so that the first protrusion 222 is located inside the first flange. Then, the die holder 31 further rotates a certain angle along the circumferential direction of the extrusion chamber 22 to the second convex edge, and the second convex edge circumferentially limits the first convex portion 222.

It will be appreciated that the first protrusion 222 and the second protrusion 312 may be reversed, i.e., the first protrusion 222 is disposed on the die holder 31 and the second protrusion 312 is disposed on the extrusion chamber 22.

It is also understood that the second convex portion 312 can also be configured to include a first convex edge extending along the circumferential direction of the die holder 31, a second convex edge connected to the first convex edge and extending axially toward the die holder 31, and a third convex edge opposite to the first convex edge. The first protrusion 222 rotates to the second protrusion along the inner circumference of the groove formed by the first protrusion and the third protrusion, so that the first protrusion 222 and the second protrusion 312 form a reliable axial position limit.

Embodiment 3: the present solution differs from embodiments 1 and 2 in that the first convex portion is provided as a first bump; the second convex part is set as a second convex point. When the die head bracket 31 is assembled on the extrusion cavity 22, the first salient point and the second salient point are in interference fit up and down, and axial pre-tightening is realized.

Embodiment 4: as shown in fig. 11, the die holder 31 and the extrusion chamber 22 are mounted by being axially inserted and sleeved. Specifically, the die head support 31 is arranged to be sleeved outside the extrusion cavity 22, a first protrusion 222 is convexly arranged on the outer side wall of the front end of the extrusion cavity 22, and the first protrusion 222 is a matching portion. A guide groove 313 which is matched with the first convex part 222 is arranged on the inner side wall of the die head bracket 31, and the guide groove 313 is a limiting part. The scheme enables the first convex part 222 and the guide groove 313 to be positioned in a space formed by sleeving the extrusion cavity 22 and the die head support 31. When the die holder and extrusion chamber are in place, the first protrusion 222 and guide groove 313 are not exposed for aesthetic reasons. Of course, the sleeving manner of the extrusion cavity 22 of the die holder 31 can be replaced by sleeving the extrusion cavity outside the die holder, and the positions of the first protrusion 222 and the guide groove 313 can be interchanged between the extrusion cavity 22 and the die holder 31 as long as the first protrusion 222 and the guide groove 313 are not exposed.

On this basis, in order to prevent the die holder 31 from slipping out of the extrusion chamber 22, the axial frictional force between the first protrusion 222 and the guide groove 313 is relatively increased by setting the radial clearance Δ X between the first protrusion 22 and the guide groove 313 to 0mm or less, and Δ X is 0mm or less and 0.2mm or less. When Δ X is smaller than 0mm, since the gap between the first protrusion and the guide groove is too small, the die holder 31 is difficult to be attached to the extrusion chamber 22 and also difficult to be detached from the extrusion chamber 22, thereby affecting the user experience. When Δ X is larger than 0.2mm, since the clearance between the first protrusion 222 and the guide groove 313 is too large, the axial friction force between the first protrusion 222 and the guide groove 313 is greatly reduced, and is not enough to support the die holder 31, and the die holder 31 is very likely to fall. In particular, when the elastic member is added to the pasta machine, the elastic member directly or indirectly pushes the extrusion screw axially, and the extrusion screw exerts an ejection elastic force like a die holder, and at this time, it is more necessary to ensure that the radial gap Δ X between the first protrusion 222 and the guide groove 313 is between 0mm and 0.2 mm.

Embodiment 5: in order to prevent the safety problem that the extrusion screw is exposed to hurt the user by mistake when the user starts the wheaten food machine by mistake without installing the die head bracket, the elastic piece 4 for axially pressing the extrusion screw is arranged in the wheaten food machine of the scheme, and reference can be made to fig. 2. On the basis, in order to simplify the specific structures of the limiting part and the matching part and provide installation guidance for users, the limiting part and the matching part are also provided with magnetic pieces with opposite magnetism and larger attraction force than the elastic force of the elastic piece, namely, the magnetism of the limiting part is opposite to that of the matching part. Like this, because the suction user of magnetic part will be with the die head support attract extrude on the chamber and counterpoint the accuracy when being close to the extrusion chamber gradually, the user just can be once only with the die head support installation to extrude on the chamber. And in order to prevent the elastic force of the elastic piece from ejecting the die head bracket axially, the suction force between the magnetic limiting part and the magnetic matching part is also set to be larger than the elastic force of the elastic piece.

It can be understood that the elastic element is not arranged in the pasta machine, and the limit part and the matching part are still arranged to be magnetic elements with opposite magnetism, so that the cost of the die cover 32 can be saved. Certainly, if not omitting the mould lid, the appeal that magnetic spacing portion formed in magnetic cooperation portion just plays the axial pretension effect, and the user can realize the one-hand installation, experiences and feels the preferred. In the present application, the structures of the fitting portion and the mounting portion are not particularly limited.

It should be noted that, as for the above embodiments 1 and 2 and mentioned possible alternatives, it can be summarized that the mating portion is a first protrusion 222 protruding along the radial direction of the extrusion chamber side wall, the limiting portion includes a second protrusion 312 protruding along the radial direction of the die holder 31, and the first protrusion 222 and the second protrusion 312 are oppositely arranged and axially clamped with each other; or, the first convex portion 222 is arranged on the side wall of the die head bracket, the second convex portion 312 is arranged on the side wall of the extrusion cavity, and the first convex portion 222 and the second convex portion 312 are oppositely arranged in the facing direction and are axially clamped with each other. The axial fixation of the die holder 31 and the extrusion chamber 22 is realized by the axial engagement of the first protrusion 222 and the second protrusion 312, so that the die holder 31 is prevented from falling off. The clamping installation mode has a simple structure, and is convenient for user operation. Similarly, the first protrusion 222 may be disposed on the sidewall of the die holder 31, the second protrusion 312 may be disposed on the sidewall of the extrusion chamber 31, and the first protrusion 222 and the second protrusion 312 are disposed oppositely and axially clamped to each other.

In one embodiment of the present application, as shown in fig. 10, the present solution eliminates the existing die cover structure since the present solution is directly installed with the extrusion chamber through the die holder. Therefore, under the condition that the die head cover is not installed, the extrusion screw rod rotates forwards and backwards in the processing process of the wheaten food machine, and the rotation acting force of the food material on the die head support is opposite to the rotation direction of the die head support when the die head support is installed in the extrusion cavity in one steering process, so that the die head support rotates backwards to fall off, and even the die head support is thrown out to hurt a user.

In order to solve the safety problem that the die head support 31 is reversely screwed out and falls down or even accidentally injures a user, a rotation stopping groove 3121 is arranged on one side of the second convex part 312 communicated with the rotating groove 314, a rotation stopping convex rib 2221 is arranged on a matching part, and the matching part is a first convex part 222 arranged on the extrusion cavity 222. After the rotation stopping convex ribs 2221 are clamped into the rotation stopping grooves 3121, the circumferential interaction of the rotation stopping convex ribs 2221 and the rotation stopping grooves 3121 forms the circumferential positioning of the first convex parts 222 and the second convex parts 312, and the risk that the die head support 31 is reversely screwed out and falls or even accidentally injures a user is greatly reduced. Similarly, a rotation stopping rib 2221 may be provided on one side of the second protrusion 312, which is communicated with the rotation groove 314, and a rotation stopping groove 3121 is provided on the matching portion, which is the first protrusion 222 provided on the extrusion cavity 222, so that the risk that the die head support 31 is rotated out reversely and falls down, or even accidentally injures a user is greatly reduced.

In some embodiments of the present application, as shown in fig. 5 to 7, in order to ensure that the axial limiting of the mating portion and the second protrusion 312 is more reliable after the mating portion rotates into the rotating groove and the second protrusion 312 is axially limited, which not only can avoid the phenomenon that the mating portion and the second protrusion 312 slip, but also can reduce the rotation angle when the user installs the die holder 31 relatively small without affecting the experience feeling, the length of the second protrusion 312 along the circumferential direction of the die holder 31 is set to be L, and L is greater than or equal to 2mm and less than or equal to 40 mm. When the stopper including the guide groove 313, the rotary groove 314, and the second projection 312 is provided in the extrusion chamber, the value of L is the length in the axial direction of the extrusion chamber 22. Therefore, the length of the second convex part along the circumferential direction of the extrusion cavity or the circumferential direction of the die head support is L, and L is more than or equal to 2mm and less than or equal to 40 mm. When L is less than 2mm, the circumferential length of the engagement portion with the second projection 222 is too narrow, so that the engagement portion and the second projection 222 are easily slipped and released; when L is greater than 40mm, the circumferential length of the matching portion matching with the second protrusion 222 is too wide, so that a user needs to rotate a large angle to mount the die holder on the extrusion cavity 22, and the user experience is seriously affected. In a preferred embodiment, the mating portion is provided with a first protrusion 222 as shown in fig. 5.

In some embodiments of the present application, as shown in FIG. 7, the length of the rotary slot 314 in the axial direction of the die holder 31 is L2, 6mm L2 mm 60mm, and preferably L2 may be 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40 mm. When L2 is larger than or equal to 60mm, when a user installs the die head bracket, the angle of rotation is large, and the hand needs to be bent extremely, so that the installation experience of the user is influenced, and when L2 is smaller than 6mm, the circumferential length of the first convex part 222 clamped into the rotating groove 314 is too narrow, and the first convex part is easy to slip out of the guide groove 313. The radial width of the rotary groove 314 is L1, L1 is more than or equal to 1mm and less than or equal to 10mm, and the preferable L2 can be 3mm, 5mm and 7 mm. When L1 is larger than 10mm, the first protrusion 222 caught in the rotation groove 314 needs to be increased in size, thereby increasing the cost. When L1 is smaller than 1mm, the gap between the rotation grooves 314 is too narrow, and the first protrusions 222 are difficult to be inserted into and removed from the rotation grooves 314.

More specifically, as shown in FIG. 8, the first protrusion 222 is further provided with a thickness H1, 1mm H1 mm 10mm, and the preferred value of H1 may be 2mm, 4mm, 6mm, 8 mm. When H1 is greater than 10mm, the excessive thickness of first protrusion 222 causes the center of gravity of first protrusion 222 to be far from the extruder barrel or die holder, which is prone to breaking when subjected to large axial forces. When H1 is less than 1mm, the first protrusion 222 is not thick enough and easily slips off when it is engaged with the second protrusion. As shown in FIG. 9, the first convex portion 222 has a radial width H3, H1 15mm or less at 1mm or more, preferably 3mm, 6mm, 9mm, 12 mm. The circumferential length of the first convex portion 222 is H2, 2mm H1 mm 30mm, preferably 9mm, 11mm, 13mm, 15mm, 17mm, 21mm, 25 mm.

Under some embodiments of the present application, as shown in fig. 5 to 7 and 11, in order to ensure that the fitting portion can be fitted into smooth reciprocating movement along the guide groove 313 in the axial direction for fitting or removing the die holder 31, it is also provided that the circumferential dimension of the guide groove 31 is not smaller than the circumferential dimension of the fitting portion. Further, in order to ensure that the engagement portion is circumferentially rotated along the rotation groove 313 until axially retained by the second projection 312, the circumferential dimension of the engagement portion is not less than the circumferential dimension of the rotation groove 313. In a preferred embodiment, the mating portion is a first protrusion 222 disposed on an outer sidewall of the extrusion chamber.

Under some embodiments of this application, through setting up the protruding locating of cooperation portion the lateral wall of extrusion chamber 22 and along this lateral wall circumference equipartition setting for when the lateral wall of extrusion chamber 22 received the pulling force that die head support 31 outwards pulled out, the extrusion chamber 22 outside can the atress even, avoids extrusion chamber fracture or spacing portion wearing and tearing. As shown in fig. 8 and 11, the engaging portion is a first protrusion 222 which is provided on the outer side wall of the extrusion chamber and protrudes radially outward, and the number of the first protrusions 222 is between 2 and 6, preferably 3, 4 or 6. In a similar way, the inner side wall circumference equipartition of die head support 31 is still set up to spacing portion edge, spacing portion and cooperation portion one-to-one setting can prevent that die head support 31's inside wall from receiving extrusion chamber 22 when inwards pulling force of holding die head support 31, and die head support 31's inside wall atress is more balanced. When the die holder 31 is mounted in this way, the die holder 31 is less likely to be biased to be caught in the extrusion chamber 22, and abrasion of the positioning portion and the fitting portion is reduced. As shown in fig. 8 and 11, the stopper portions are provided on the inner side wall of the die holder 31 in a number and positions corresponding to the arrangement of the first convex portions one by one.
