Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
As shown in fig. 1 to 6, a rotary cutter device 10 for easy replacement includes: a rotary cutter seat 11, a plurality of rotary cutters 12, a sleeve 13 and a snap safety seat 14. Wherein the sleeve 13 is used for mounting a plurality of rotary blades 12. The snap safety seat 14 is connected to the sleeve 13 to detachably mount the sleeve 13 to the rotary cutter head 11.
As a specific structure. A plurality of rotary blades 12 are detachably mounted to the sleeve 13 in the circumferential direction of the sleeve 13 so as to facilitate the detachment of the rotary blades 12 when the rotary blades 12 need to be replaced. Specifically, the rotary blade 12 may be detachably mounted to the sleeve 13 by screws 16.
Alternatively, the rotary cutter blade may be secured to and integral with the sleeve by other means, such as riveting, welding or injection molding. When the rotary blade needs to be replaced, the sleeve is directly detached to be communicated with the sleeve for replacement.
The turret block 11 is provided with a drive shaft 111. A driving head 112 is connected to one end of the driving shaft 111, and the driving head 112 engages with the sleeve 13 to drive the sleeve 13 to rotate. Specifically, the other end of the driving shaft 111 is connected to a motor to be driven by the motor, thereby driving the driving head 112 to rotate. The sleeve 13 is sleeved on the outer periphery of the driving head 112. The driving head 112 is formed with a driving male tooth 113, a mounting cavity 114, and a catching groove 115. The inner side wall of the sleeve 13 is formed with drive female teeth 131 that mesh with the drive male teeth 113. The driving head 112 drives the sleeve 13 to rotate by engaging the driving male teeth 113 with the driving female teeth 131.
A snap safety seat 14 is fixed to one end of the sleeve 13 by means of a screw 16. The snap safety seat 14 is formed with a flexible snap 141. A flexible catch 141 is used to removably connect the sleeve 13 to the drive head 112. Specifically, the flexible catch 141 is formed with a catch projection 142. The snap projection 142 is adapted to cooperate with the catch groove 115 to removably connect the sleeve 13 and the snap safety seat 14 to the drive head 112. The wall of the mounting cavity 114 is formed with a guide surface at the end of the drive head 112. When the flexible buckle 141 is installed, the flexible buckle 141 extends into the installation cavity 114, the buckle protrusion 142 deforms under the pressing action of the guide surface, and is clamped into the blocking groove 115 when the flexible buckle continues to extend into the installation cavity 114 to a specific position. At this time, the flexible catch 141 and the catch projection 142 are restored to their shapes by the sudden disappearance of the pressing force. When the flexible buckle 141 and the buckle protrusion 142 return to the deformed state, they collide with the wall of the blocking groove 115 and the wall of the installation cavity 114, and then generate a loud sound. The sound can alert the user that the snap tab 142 has snapped into the catch recess 115 and the sleeve 13 is in place.
One end of the sleeve 13 is formed with a U-shaped groove 132. A release button 15 is provided in the U-shaped channel 132. The release button 15 is used for the user to press the flexible buckle 141, so that the flexible buckle 141 is deformed again until the flexible buckle is separated from the blocking groove 115, and the buckle mounting seat and the sleeve 13 are further realized. Specifically, release button 15 is slidably connected to the slot wall of U-shaped slot 132 and contacts flexible catch 141 at one end. When the snap mount and the sleeve 13 need to be removed, the release button 15 is pressed.
Particularly, the rotary cutter device 10 convenient to replace can detachably mount the rotary cutter blade 12 to the driving head 112 through the buckle safety seat 14 and the sleeve 13, only needs to detach the sleeve 13 through the buckle safety seat 14 when different rotary cutter blades 12 need to be replaced, and then the corresponding rotary cutter blade is replaced and then installed to the driving head 112. The rotary blade 12 can be easily removed for cleaning by such a structure.
The rotary knife blade 12 and the sleeve 13 of the rotary knife device 10 convenient to replace are clamped into the blocking groove 115 of the driving head 112 through the flexible buckle 141 and are detachably connected to the driving head 112, when the rotary knife blade 12 rotates, and when food after being poured or shaken for cleaning, the rotary knife blade 12 and the sleeve 13 can avoid the falling condition through the matching of the groove wall of the blocking groove 115 and the buckle bulge 142, and the stability and the safety of the structure are higher. Meanwhile, when the buckle protrusion 142 of the flexible buckle 141 is clamped into the blocking groove 115, a loud sound is generated, and the sound has a warning effect on a user, so that the situation that the user turns on the rotary blade 12 and the sleeve 13 in place due to misassembly is avoided, and the product and the user are injured due to the fact that the machine is turned on due to misassembly is avoided.
The rotary cutter device 10 convenient for replacement enables the sleeve 13 to rotate forwards or backwards under the driving of the driving head 112 through the meshing of the driving male teeth 113 and the driving female teeth 131, and further enables the rotary cutter blade 12 to have the functions of forward rotation and backward rotation.
As a specific embodiment, the snap-on safety seat 14 is provided with a snap part 143. The latch 143 has an arc-shaped recess 144 for defining a sliding direction of the release button 15 in cooperation with the U-shaped groove 132.
Specifically, the retaining member 143 presses the release button 15 into the U-shaped groove 132 by the arc-shaped recess 144 abutting the outer periphery of the release button 15, so that the release button 15 can slide only in a specific direction under the combined restriction of the groove wall of the U-shaped groove 132 and the arc-shaped recess 144. The specific direction is a direction in which one end of the release button 15 presses the flexible catch 141 to deform the flexible catch 141 and disengage from the catch groove 115.
Further, the release button 15 is cylindrical. The width of the catching part 143, the outer diameter of the release button 15 and the groove width of the U-shaped groove 132 are equal. The arcuate recess 144 engages the release button 15 and the release button 15 is press fit onto the bottom of the U-shaped channel 132 and engages the bottom of the U-shaped channel 132. When cooking food can be avoided to such structure, the cleanness in installation cavity 114 is guaranteed in the large granule material entering installation cavity 114.
Still further, the release button 15 is formed with a stopper 151. The blocking member 151 is adapted to cooperate with the click member 143 to prevent the release button 15 from falling out of the U-shaped groove 132. The blocking member 151 is disposed between the latching part 143 and the flexible latch 141.
Specifically, when the release button 15 is pressed to press the flexible catch 141 to deform the flexible catch 141 and disengage from the catching groove 115, the stopper 151 is disengaged from the catching part 143. When the flexible latch 141 is engaged with the blocking groove 115, the blocking member 151 contacts the latch pressing member 143 under the effect of the flexible latch 141 abutting against one end of the release button 15, so that the release button 15 is structurally stable, and the release button 15 is prevented from being loosened.
Further, one end of the release button 15 for contacting the flexible catch 141 is formed with a curved surface 152. The curved surface 152 is used for wrapping and pressing two sides of the flexible buckle 141 to ensure the pressing operation precision.
In a specific embodiment, the retaining groove 115 is arc-shaped, and the length of the arc-shaped edge of the retaining groove 115 in the circumferential direction of the driving head 112 is greater than the width of the snap projection 142. There is a certain fit clearance between the male drive teeth 113 and the female drive teeth 131. With this arrangement, the snap projection 142 can slide within the retaining groove 115 along the wall of the retaining groove 115 within a certain range of travel, so that the sleeve 13 fixedly connected to the snap safety seat 14 can rotate relative to the driving head 112.
Further, the inner wall of the sleeve 13 is formed with a diamond-shaped boss 133. The drive head 112 is formed with two circular-arc bosses 116 around the circumferential direction of the drive head 112. The two circular arc bosses 116 are respectively located at two sides of the diamond-shaped boss 133 and are both formed with a matching inclined plane 117 for matching with two adjacent inclined planes 134 of the diamond-shaped boss 133. When the sleeve 13 is mounted in place, the two adjacent inclined surfaces 134 of the diamond-shaped projection 133 are located below the mating inclined surfaces 117 formed by the two circular arc projections 116, respectively, in the direction of the rotational axis 17 of the drive head 112. Due to the relative rotation between the sleeve 13 and the driving head 112, when the driving head 112 rotates in the forward direction, the driving head 112 rotates relative to the sleeve 13 within a certain travel range, so that one of the two matching inclined surfaces 117 matches with one of the two adjacent inclined surfaces 134 of the diamond-shaped boss 133 to interfere with the diamond-shaped boss 133, thereby preventing the sleeve 13 from being displaced in the direction of the rotation axis 17, further preventing the sleeve 13 from being disengaged from the driving head 112, and further ensuring the stability of the installation structure of the sleeve 13 and the rotary blade 12. Similarly, when the drive head 112 is rotated in the opposite direction, the other of the two mating ramps 117 mates with the other of the two adjacent ramps 134 of the diamond shaped boss 133 to interfere with the diamond shaped boss 133.
Specifically, the two circular arc bosses 116 are oppositely disposed about the rotation axis 17. One of the two diagonal lines of the diamond-shaped projection 133 is perpendicular to the rotation axis 17. The distance between the adjacent one ends of the two circular-arc bosses 116 in the circumferential direction of the circular-arc bosses 116 is larger than the width of the rhombic boss 133 in the circumferential direction of the sleeve 13. This ensures that the diamond-shaped projection 133 can pass through the gap between the adjacent ends of the two circular arc projections 116 to reach under the two circular arc projections 116 when the sleeve 13 is mounted.
In a preferred embodiment, the two circular arc bosses 116 are provided with a matching inclined surface 117 at both ends. This allows the diamond shaped bosses 133 to pass through the gaps from both ends of the circular arc boss 116, facilitating the installation of the sleeve 13.
Alternatively, the sleeve may be provided with two diamond shaped bosses. The two diamond-shaped bosses are oppositely arranged relative to the rotational axis of the sleeve and are oppositely arranged relative to the rotational axis of the drive head when the sleeve is mounted in place.
In a specific embodiment, the outer peripheries of the driving male teeth 113 and the driving female teeth 131 are provided with soft protective layers. The soft protective layer serves to cushion the force between the driving male teeth 113 and the driving female teeth 131. Specifically, the thickness range of the soft protective layer is 0.5mm or more and 1mm or less.
In the present embodiment, the number of the flexible snaps 141, the U-shaped grooves 132, and the release buttons 15 is two. The two U-shaped grooves 132 are oppositely disposed about the axis of rotation 17 of the drive head 112. The two flexible catches 141 are also oppositely disposed about the axis of rotation 17 of the drive head 112 when the sleeve 13 is in place.
As an alternative, the number of the flexible buckles, the U-shaped grooves and the release buttons may be multiple, and the number may be specifically set according to the actual requirement of the product.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
