It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

In a first aspect, the present application discloses a knife tackle structure. This knife tackle structure can be applicable to cooking equipment such as soybean milk machine, broken wall machine, meat grinder, mixer, juice extractor, cooking machine.

As shown in fig. 4-6, one embodiment of the present application provides a knife block structure comprising:

the upper knife tackle 100, the upper knife tackle 100 is provided with a limiting part 101; the lower cutter set 200 is provided with a first matching part 201; the upper tool set 100 and the lower tool set 200 are assembled in an inserting mode, the upper tool set 100 is in clearance fit with the lower tool set 200, and the first matching portion 201 and the limiting portion 101 are limited mutually.

The main body of the upper knife group 100 in this embodiment may be substantially configured as a cylinder, the main body of the lower knife group 200 may be substantially configured as two cylinders with different radii, and the cylinder with the smaller radius in the lower knife group 200 is configured to be assembled with the cylinder of the upper knife group. The central part of the cylinder of the upper knife group can be provided with a limiting part 101, and the outside of the cylinder with smaller radius in the lower knife group 200 is provided with a first matching part 201. Here, the position limiting portion 101 may be a concave structure, and when the position limiting portion 101 is a concave structure, the first fitting portion 201 should be a convex structure. The shape and specific position of the limiting part and the first matching part are not particularly limited. The structure that the first engaging portion and the stopper portion can be engaged with each other in the art is applicable to the structure of this example.

The upper knife tackle 100 and the lower knife tackle 200 are assembled in an inserting mode in the embodiment. A plug connection is understood to mean a connection body that can be displaced axially within another connection body, a plug connection being a movable connection, for example: and (4) sleeving. The method comprises the following steps: the upper blade group 100 is sleeved outside the lower blade group 200 along the axial direction of the lower blade group 200.

The upper blade set 100 and the lower blade set 100 are in clearance fit in this embodiment. A clearance fit refers to a fit having a clearance (including a minimum clearance equal to zero) that allows relative movement after the bore and shaft are mated.

Due to the clearance fit between the upper blade set 100 and the lower blade set 200, there may be a problem that the upper blade set 100 and the lower blade set 200 may be separated or rotated during use. The limiting portion 101 and the first fitting portion 201 limit each other, thereby limiting the movement of the lower blade set 200 in the first direction and the second direction with respect to the upper blade set 100. That is, when the lower blade set 200 is rotated or moved in a certain direction, the first engagement portion 201 is engaged or abutted in the stopper portion 102 due to the presence of the stopper portion 102, thereby preventing the movement of the lower blade set 200 in the first direction and the second direction with respect to the upper blade set 100. Here, the first direction and the second direction are perpendicular to each other, the first direction is defined as the direction of the knife edge of the knife group structure, and can also be understood as the working direction or the rotating direction or the cutting direction of the knife group structure, and the second direction is the axial direction of the knife group structure. It should be noted that, in order to ensure that the upper blade set and the lower blade set are limited in movement in the first direction after the first matching portion 201 and the limiting portion 101 are limited, the position relationship between the limiting portion 101 and the first matching portion 201 should be understood that the limiting portion 101 is at least partially located in the first direction of the blade set structure. Illustratively, when the knife block structure in the embodiment is used for the meat chopper, the upper knife block and the lower knife block are assembled according to the above, so that the upper knife block and the lower knife block cannot move circumferentially or fall off axially when the meat chopper works. After the power is supplied, the whole knife set rotates at a high rotating speed, and in order to better crush the meat blocks into minced meat or meat paste, the rotating direction of the knife set is consistent with the direction of the knife edge. At this time, the first direction is understood as the direction of the knife edge, that is, the mutual limit of the limit portion and the first matching portion limits the movement of the lower knife group towards the knife edge, as shown in fig. 6, the knife edge of the upper blade 104 is in the counterclockwise direction when viewed from the bottom, and it can be understood that the limit portion 101 is at least partially located in the counterclockwise direction, and the mutual limit of the first matching portion 201 and the limit portion 101 can be realized when the knife group structure works.

The knife tackle structure of this embodiment is through last knife tackle and lower knife tackle clearance fit to spacing realization reliable assembly each other through spacing portion and first cooperation portion. Compare the close fit of prior art's recess and boss, it is big to lead to the fitting surface, and the installation is hard with dismantling. The utility model provides a knife tackle structure fitting surface is little, and the installation is laborsaving light with dismantling, can not take place to drop and collide.

As shown in fig. 4 and 7, the lower blade set 200 is further provided with a second engaging portion 202, and when the first engaging portion 201 is limited to the limiting portion 101, a lower end surface of the second engaging portion 202 is in clearance fit with an upper end surface of the upper blade set 100. It will be appreciated that, as shown in fig. 4, when the blade unit structure is not assembled, the lower end face of the second fitting portion 202 refers to the end face away from the upper blade unit 200, and the upper end face of the upper blade unit 100 refers to the end face away from the lower blade unit 200. When the first engaging portion 201 is limited by the limiting portion 101, the second engaging portion 202 can completely penetrate through the upper tool set 100 to engage with the upper end surface of the upper tool set 100. This arrangement prevents the upper blade group 100 and the lower blade group 200 from coming off each other in the axial direction. Meanwhile, the end face of the upper tool set 100 is utilized, and another limiting part is not required to be designed independently, so that the tool set is simpler in structure and convenient to process. Compared with the prior art that the lower part of the lower cutter set is only provided with the dead axle moving end, the matching of the second matching part 202 and the upper end surface of the upper cutter set 100 is increased in the embodiment, so that the assembly of the cutter set is more reliable and stable, the installation and the disassembly are easy and labor-saving, and the assembly efficiency is improved. And this mode of setting does not influence the overall structure of last knife tackle for mould simple structure.

In a practical manner, the lower end surface of the second fitting portion 202 and the upper end surface of the upper blade group 100 are in a clearance range of 0-0.5 mm. The clearance fit range ensures labor-saving and convenient assembly and disassembly, and the smaller the ideal value of the clearance range is, the better the clearance range is, and the preferable clearance range is 0-0.2 mm. The problem that the upper cutter set and the lower cutter set are axially matched and loosened due to overlarge gaps, so that the upper cutter set and the lower cutter set collide with each other during working to generate noise can be avoided; in addition, the clearance range can also be beneficial to keeping the upper cutter set and the lower cutter set concentric after assembly, the problem that the cutter set structure is abraded due to eccentricity under the driving of an external driving structure is solved, and the service life of a product is prolonged.

As a practical way, as shown in fig. 5-7, the upper tool set 100 includes an upper tool holder 103 and an upper blade 104 mounted on a side wall of the upper tool holder 103, a through hole 105 is formed in the center of the upper tool holder 103 along the axial direction thereof, and the limiting part 101 is located on the inner wall of the through hole 105;

the lower tool set 200 comprises a lower tool rest 203 and a lower blade 204 arranged on the side wall of the lower tool rest 203, wherein a connecting shaft 205 is fixedly connected to the lower tool rest 203, and the connecting shaft 205 is matched with the through hole 105.

Here, the upper blade 104 and the upper blade holder 103 may be integrally formed, or may be separately processed and then fixedly connected together; the lower blade 204 and the lower blade holder 203 can be integrally formed or can be separately machined and then fixedly connected together. The upper blade 104 can be two blades or more than two blades which surround the side wall of the upper blade holder 103 anticlockwise or clockwise; the lower blade 204 may be two blades or more than two blades surrounding the sidewall of the lower blade holder 203 counterclockwise or clockwise, which is not limited in this embodiment. Each part is easy to process, simple in structure and convenient to assemble, and the upper cutter set and the lower cutter set can be conveniently assembled.

As a realizable manner, in order to facilitate the second matching portion 201 to match with the upper end face of the upper blade group 100, the first matching portion 101 and the second matching portion 102 are arranged at an interval in the axial direction of the connecting shaft 205, or have a certain distance in the axial direction, and the distance is not limited herein and depends on the axial length of the connecting shaft 205. The arrangement mode is also beneficial to reducing the weight of the cutter group structure and simultaneously enabling the lower cutter framework to be simple.

Note that the first fitting portion 201 and the second fitting portion 202 are provided at an interval in the axial direction of the connecting shaft 205. It is understood that, as shown in fig. 7, the first mating portion 201 and the second mating portion 202 are located at the top and the bottom of the connecting shaft 205, respectively, and the first mating portion 201 and the second mating portion 202 are located on the same axis. As shown in fig. 4, the top of the connecting shaft 205 can be understood as a position close to the upper blade set 100 when the blade set structure is not assembled, and the bottom of the connecting shaft 205 can be understood as a position away from the upper blade set 100 when the blade set structure is not assembled.

As an implementation manner, as shown in fig. 6, the limiting portion 101 includes a first groove 1011 and a second groove 1012 sequentially opened along the axial direction of the inner wall of the through hole 105, the first groove 1011 is communicated with the second groove 1012, one end of the first groove 1011 away from the second groove 1012 penetrates through the top of the upper tool set 100, one end of the second groove 1012 away from the first groove 1011 penetrates through the bottom of the upper tool set 100, and the dimension of the second groove 1012 along the circumferential direction of the through hole 105 is greater than the dimension of the first groove 1011 along the circumferential direction of the through hole 105.

In this embodiment, a first groove 1011 and a second groove 1012 are formed along the inner wall of the through hole 105 in the axial direction, and the first groove 1011 and the second groove 1012 are recessed in a direction extending outward from the inner wall of the through hole 105 but not penetrating the outer wall. The dimension along the circumferential direction of the upper blade set 100 may be understood as a dimension extending in the circumferential direction of the cylinder when the upper blade set 100 is substantially cylindrical. First recess 1011 and second recess 1012 communicate and the axial runs through last knife tackle 100, when being favorable to last knife tackle 100 and lower knife tackle 200 to assemble, first cooperation portion 201 and the axial displacement of second cooperation 202 at last knife tackle 100, be convenient for the cooperation of second cooperation portion 202 and the up end of last knife tackle 100, first cooperation portion 201 moves to in second recess 1012 in first recess 1011, at this moment, lower knife tackle 200 just can rotate thereby drive first cooperation portion 201 and spacing in second recess 1012, play and prevent last knife tackle and lower knife tackle in axial removal and circumferential rotation. The structure of the limiting part 101 of the present embodiment not only can realize reliable assembly of the upper blade group and the lower blade group, but also is convenient for production, manufacturing and processing.

As an achievable way, specifically, as shown in fig. 6, the second groove 1012 includes a first portion 10121 and a second portion 10122 extending along the circumferential direction of the through hole 105, and when the first mating portion 201 is located at the first portion 10121, the lower tool set 200 can be rotated so that the first mating portion 201 is in clearance fit with the inner wall of the second portion 10122. It should be appreciated that the first portion of the second recess 1012, which is coaxial and circumferentially the same size as the first recess, can form a passageway for the second mating portion 202 to pass through when the lower blade set 200 is inserted inside the upper blade set 100. The second part of the second groove 1012 mainly plays a limiting role, when the first matching part 201 is located at the first part 10121, the lower cutter set 200 is rotated, and the inner walls of the first matching part 201 and the second part 10122 are in clearance fit to realize limiting. Second recess processing is simple and convenient in this mode, realizes spacingly when being convenient for down the rotatory assembly of knife tackle simultaneously, improves assembly efficiency, and clearance fit is easy to assemble and dismantles, and is light laborsaving.

Further, the first groove 1011 and the second groove 1012 of the position-limiting portion 101 are communicated with each other, so that the position-limiting portion 101 may be an L-shaped groove as a whole; it can be understood that: the first mating portion 201 is in clearance fit with the second portion 10122 of the second groove 1012, and the second mating portion 202 passes through the first groove 1011, so that the dimensions of the first groove 1011 and the second portion 10122 of the second groove 1012 along the circumferential direction of the upper blade set 100 should be slightly larger than the dimensions of the first mating portion 201 and the second mating portion 202 along the circumferential direction of the upper blade set 100.

On the basis of the foregoing embodiment, the working process of the knife group structure of this embodiment can be described as follows: as shown in fig. 8-11, the upper tool holder 103 of the upper tool set 100 is inserted into the connecting shaft 205 of the lower tool set 200 from the through hole 105, the second mating portion 202 sequentially passes through the first portion 10121 and the first groove 1011 of the second groove 1012 along with the axial movement of the through hole 105 on the connecting shaft 205, the lower end surface of the second mating portion 202 is flush with the top end of the first groove 1011, the first mating portion 201 is completely located in the first portion 10121 of the second groove 1012, the lower tool set 200 is rotated in the first direction, the lower end surface of the second mating portion 202 is in clearance fit with the upper end surface of the upper tool set 100, the first mating portion 201 is in clearance fit with the inner wall of the second portion 10122 of the second groove 1012, the assembly of the upper tool set 100 and the lower tool set 200 is completed, the upper tool set 100 and the lower tool set 200 are prevented from falling off or rotating in the opposite direction, and the operation is only required during disassembly. Wherein, the top end of the first groove 1011 refers to the end of the first groove 1011 away from the second groove 1012; the first direction refers to the direction of rotation or working direction of the knife block structure.

As an implementable manner, the clearance range of the clearance fit of the first fitting part 201 with the inner wall of the second part 10122 is 0-0.5 mm. The clearance fit range ensures labor-saving and convenient assembly and disassembly, and the smaller the ideal value of the clearance range is, the better the clearance range is, and the preferable clearance range is 0-0.2 mm. As shown in fig. 12, the clearance range in the embodiment is 0.2mm, so that the reliable assembly of the cutter set structure can be realized, the problem that the upper cutter set and the lower cutter set are matched to each other to cause looseness due to overlarge clearance, so that noise is generated due to mutual collision is avoided, and the disassembly and assembly of the cutter set structure are facilitated; in addition, the clearance range can also be beneficial to keeping the upper cutter group and the lower cutter group concentric after assembly, the problem that the cutter group structure is seriously abraded due to eccentricity under the driving of an external driving structure is reduced, and the service life of a product is prolonged.

As an implementation manner, each of the first grooves 1011, the first fitting parts 201 and the second fitting parts 202 is at least one, and the number of the second grooves 1012 is the same as that of the first grooves 1011. In this embodiment, the first groove 1011, the first matching portion 201 and the second matching portion 202 are at least one, that is, the first groove 1011, the first matching portion 201 and the second matching portion 202 can be one, two or more than two, so that the upper blade assembly 100 and the lower blade assembly 200 can be assembled reliably, and the structure is stable. It should be noted that the first grooves 1011 are used for the movement of the second matching portion 202, and the second grooves 1012 are used for matching with the first matching portion 201, so the number of the second grooves 1012 is the same as that of the first grooves 1011, and the number of the first grooves 1011 needs to be greater than or equal to that of the first matching portion 201 or the second matching portion 202. Preferably, two first grooves 1011 are oppositely arranged on two sides of the inner wall of the upper tool set 100, and the second groove 1012 is arranged corresponding to the first grooves 1011; the two first matching parts 201 are oppositely arranged at the bottom of the outer wall of the lower cutter set 100, and the two second matching parts 202 are oppositely arranged at the top of the outer wall of the lower cutter set 100. The structure of the cutter set is simplified, the weight of the lower cutter set is reduced, and the upper cutter set 100 and the lower cutter set 200 are more stably and reliably matched.
