Description

Technical Field

[0001] The utility model relates to a material cutting technology, in particular to a feeding device. Background Art

[0002] Artificial feed for silkworms is mainly made of dozens of ingredients such as mulberry leaf powder, soybean powder, corn powder, etc. When using the powdered artificial feed, it is mixed with water in a certain proportion, shaped and packaged, and then steamed at high temperature to make mature feed blocks. When raising silkworms, the division and feeding of feed blocks are important links in the raising operation, and the manual operation method is labor-intensive, low in work efficiency, and cumbersome. Therefore, the development of supporting feed feeding equipment can effectively give play to the advantages of raising silkworms with artificial feed.

[0003] The inventor observed the feed after cutting and found that the feed contained a large amount of feed debris. These feed debris have affected the precise cutting and feeding effect of the feed block. The inventor analyzed the phenomenon and found that the reciprocating cutting motion trajectories of the cutter overlapped. After the cutter completed the feed cutting action, it was easy to contact the end face of the feed again during the return stroke. During the re-contact process, a large amount of feed debris was caused, which in turn caused the shape of the fed feed to be irregular, the feeding to be uneven and unstable, and there were many unformed small debris. The moisture of the feed debris evaporated quickly, affecting the eating and growth and development of the silkworm. Utility Model Content

[0042] Embodiment 1:

[0043] like Figure 1 and Figure 2 As shown, a feeding device includes a frame 10, an intermittent feeding assembly 500 is arranged on the frame 10, a support plate 20 is also arranged on the frame 10, and the support plate 20 is located in front of the discharging end of the intermittent feeding assembly 500. The frame 10 is also provided with a pressing assembly 400, a shredding assembly 100 and a knife assembly 300 from back to front, and the support plate 20 is located below the pressing assembly 400. The knife assembly 300 has a cutting function that allows the shredding assembly 100 to cut vertically downward. The shredder assembly 100 is provided with a knife-retracting station for separating the shredder assembly 100 from the material cutting surface. When the shredder assembly 100 cuts the material, the pressing assembly 400 presses the material on the support plate and places the knife assembly 300 in the cutting station. When the shredder assembly 100 returns, the pressing assembly 400 is located above the material, and the intermittent feeding assembly 500 conveys the material forward for a stroke. At the same time, the knife assembly 300 is in the knife-retracting station. When in use, the intermittent feeding assembly 500 presses the material After being fed onto the support plate, the pressing assembly 400 then moves downward to press the material, and then the shaving assembly 100 moves downward. At this time, the knife assembly 300 is in the cutting position, so that the shaving assembly 100 moves vertically downward. When the shaving assembly 100 completes cutting of the material, the shaving assembly 100 moves upward to place the knife assembly 300 in the knife retracting position, so that the shaving assembly 100 is separated from the cutting surface of the material, so that the shaving assembly 100 does not contact the material during the return process, and thus no debris is generated, thereby ensuring the material cutting quality. At the same time, when the shaving assembly 100 is separated from the cutting surface of the material, the pressing assembly 400 moves upward, the pressing assembly 400 is separated from the material, and the intermittent feeding assembly 500 conveys the material forward again for a stroke. Therefore, when the shaving assembly 100 is separated from the material, the pressing assembly 400 can press the material to prevent the shaving assembly 100 from driving the material due to the stickiness of the material when it is separated from the material, thereby ensuring the material cutting quality.

[0044] In this embodiment, if Figure 8 , Fig. 9 and Fig.10As shown, the grating assembly 100 includes a grating knife, a mounting frame and a first drive assembly 200. The grating knife is mounted on the mounting frame, and the mounting frame is connected to the power output end of the first drive assembly 200. In this embodiment, the grating knife is a thin plate structure. When the grating knife is installed, after the grating knife completes the cutting of the feed block, the inventor finds that the cutting surface of the feed block does not have a regular cutting trajectory, and some areas are protruding. Moreover, after long-term use, it is also found that the cutting surface of the feed block is a protruding arc structure. After long-term research, the inventor finds that because the grating knife is a thin plate structure and the length and width of the grating knife are large, its structural strength is not high. During installation, the grating knife is easily deformed, and during When cutting the feed block, the feed block has an axial reaction force on the cutter 2. After long-term use, the grater is prone to slight inward deformation, which causes uneven cutting trajectory of the feed block. Therefore, in this embodiment, the grater includes a grating board 1 and a folding plate 5. The upper and lower edges of the grating board 1 are connected with the folding plate 5. The folding plate 5 is located on the front side of the grating board 1, and the angle between the folding plate 5 and the grating board 1 is an obtuse angle. In this embodiment, the folding plate 5 is a plate body bent outwardly, and the plate body bent outwardly of the folding plate 5 is a flange plate 4. The flange plate 4 is provided with a plurality of mounting holes. Therefore, when the grating board 1 is placed horizontally, the grater is in a "J"-shaped structure. Further, as Figure 8 As shown, a plurality of knives 2 that arch backward are provided on the grating board 1, so that the cutting edge of the knives 2 is crescent-shaped. In this embodiment, the width of the crescent-shaped cutting edge determines that the material after cutting is in the shape of strips or filaments. A cutting channel 3 corresponding to the knives 2 is also provided on the grating board 1, and the cutting channel 3 is connected with the arch cavity of the knives 2. When the grating knife moves downward, the cutting edge of the knives 2 cuts the material, and the cut material is in the shape of filaments or strips, and finally enters the cutting channel 3 and is discharged from the front side of the grating board 1. The grating knife is a thin plate grating knife, which is stamped and formed by a stamping process. The formed knife 2 is gradually shrunk from the cutting edge position toward the grating board 1, so the knife 2 can increase the structural strength of the grating board 1. degree, and after the material is cut, the arch cavity of the tool 2 can guide the cut material, so that the cut material can be effectively discharged from the cutting channel 3, and the grater knife after stamping has a "J"-shaped structure, which increases the structural strength of the grater knife and can ensure the flatness of the grating board 1 of the grater knife. At the same time, the grating board 1 is behind the folding plate 5, thereby ensuring the reliability of the grating board 1 to grating the material. When the grating board 1 cuts the material, the material has a backward reaction force on the grating board 1, and the grating knife with the "J"-shaped structure has a high structural strength and is almost not deformed under the reaction force, thereby ensuring the reliability and accuracy of the grating knife in cutting the material.

[0045] In this embodiment, if Fig. 9As shown, in the left-right direction, the knives 2 are evenly spaced, and in the up-down direction, two adjacent rows of knives 2 are staggered, and on the vertical projection plane, as shown in FIG. Fig. 9 As shown, the cutting edges of several cutters 2 are arranged side by side to form a straight line, and the cutting edges of adjacent cutters 2 have an overlapping area. Therefore, when the grater runs downward once, a cutting track similar to a straight line can be formed on the material, thereby ensuring the reliability and efficiency of material cutting, and also facilitating the control of material cutting amount and material feed amount.

[0046] In this embodiment, if Figure 7 As shown, the mounting frame includes two mounting side plates 21 and two mounting transverse plates 22, the two mounting side plates 21 are connected by two mounting transverse plates 22, and the two mounting transverse plates 22 are spaced apart up and down, the flange plates 4 of the folding plate 5 are respectively mounted on the corresponding mounting transverse plates 22, and the rear end surface of the shaving board 1 protrudes from the rear end surface of the mounting transverse plate 22, so the tool 2 on the shaving board 1 is located behind the mounting transverse plate 22, so that the mounting frame will not affect the cutting of the material by the tool 2 during the lifting process, and the mounting frame will not contact the material, thereby ensuring the reliability of material cutting, optionally, the mounting transverse plate 22 is placed vertically, a mounting hole is opened on the flange plate 4, and a screw hole is opened on the mounting transverse plate 22, and the flange plate 4 and the mounting transverse plate 22 are locked by locking screws.

[0047] In this embodiment, if Figure 7 and Figure 2As shown, the first driving assembly 200 includes a driving motor 201 and a transmission main shaft 202. The driving motor 201 is installed on the frame 10, and the transmission main shaft 202 is rotatably installed on the frame 10. The frame 10 is a gantry frame, and the gantry frame has a cavity. The mounting frame is located in the cavity of the gantry frame. The driving motor 201 drives the transmission main shaft 202 to rotate. Flywheels 203 are arranged at both ends of the transmission main shaft 202. A connecting rod 204 is eccentrically hinged on the flywheel 203. The other end of the connecting rod 204 is hinged to the mounting side plate 21. When the driving motor 201 is working, the transmission main shaft 202 rotates, thereby rotating the flywheel 203. Since the connecting rod 204 and the flywheel 203 are eccentrically hinged, the moving trajectory of the connecting rod 204 has a high point and a low point. When the connecting rod 204 moves from a high point to a low point, the mounting frame belt The grater moves downward, and when the connecting rod 204 moves from a low point to a high point, the mounting frame drives the grater upward. Therefore, each time the flywheel 203 rotates, the mounting frame completes a lifting and lowering, and the grater completes a cutting of the material. In this embodiment, a hinge portion 23 is provided at the rear end of the mounting cross plate 22, and the connecting rod 204 is hinged to the hinge portion 23. The hinge portion 23 is a semicircular structure, and a hinge hole is provided on the hinge portion 23. A hinge shaft is passed through the hinge hole. A horn fork is provided at the bottom of the connecting rod 204, and the hinge shaft can be rotatably installed in the horn fork, and the hinge portion 23 can rotate in the horn fork, and an hinge shaft is provided on the flywheel 203, and a hinge hole is provided at the top of the connecting rod 204, and the hinge shaft can be rotatably installed in the hinge hole. Preferably, a bearing is installed in the hinge hole, and the hinge shaft is installed in the bearing.

[0048] When cutting the feed block, as the feed is cut, the inventors found that after the cutter cuts the feed block, the cutter and the cutting surface of the feed block have a large contact area. During the cutter resetting process, the feed block adheres to the cutter and is dragged by the cutter, which causes the next feed cutting amount to change, thereby causing the cutting weight of the feed block to change. Therefore, in this embodiment, if Figure 2 , Figure 3As shown, the pressing component 400 includes a lifting frame 43, a second driving component 200 and a frame 10, the second driving component 200 is installed on the frame 10, and the second driving component 200 drives the lifting frame 43 to rise and fall relative to the frame 10, a sliding member 42 is installed on the lifting frame 43, and the sliding member 42 can slide relative to the lifting direction of the lifting frame 43, and one end of the sliding member 42 is provided with a limiting portion 421 that cannot pass through the lifting frame 43, and the other end of the sliding member 42 passes through the lifting frame 43, and the sliding member 42 that passes through the lifting frame 43 is installed with a pressing member 41, and when the lifting frame 43 is in the down stroke, the limiting portion 421 is located at the lifting frame 43. The material pressing piece 41 is above the frame 43 at this time, and the material pressing piece 41 presses the material by its own weight. When the lifting frame 43 is in the upward process, the lifting frame 43 does not contact with the limiting part 421. At this time, the material pressing piece 41 still presses the material by its own weight. After the lifting frame 43 contacts with the limiting part 421, as the lifting frame 43 rises, the material pressing piece 41 rises with the lifting frame 43 and then separates from the material. Therefore, the material pressing assembly 400 presses the material by the self-weight of the material pressing piece 41. Therefore, the material pressing piece 41 can be counterweighted according to actual conditions to ensure that the material is pressed without causing damage to the material.

[0049] In this embodiment, if Figure 3 As shown, the lateral span of the material is relatively wide, and a plurality of slides 42 are installed on the lifting frame 43. The plurality of slides 42 are distributed at intervals in the lateral direction. For the convenience of processing, the spacing between two adjacent slides 42 is the same. Since a plurality of slides 42 are provided, the circumferential rotation of the pressing piece 41 relative to the lifting frame 43 can be avoided. Therefore, in this embodiment, the slide 42 can be configured as a cylinder or a polygonal cylinder. Preferably, the slide 42 is a cylinder. In other embodiments, if the lateral span of the material is relatively narrow, the slide 42 can also be configured as one. At this time, in order to avoid the circumferential rotation of the pressing piece 41 and the lifting frame 43, the slide 42 can be configured as a polygonal cylinder.

[0050] In this embodiment, if Figure 3As shown, the second driving assembly 200 includes a driving member, a rotating member 49 and a connecting member 47. The driving member is installed on the frame 10, and the power output end of the driving member is connected to the rotating member 49, and the driving member drives the rotating member 49 to rotate coaxially. One end of the connecting member 47 is eccentrically hinged on the rotating member 49, and the other end of the connecting member 47 is hinged to the lifting frame 43. The driving member drives the rotating member 49 to rotate. During the rotation process, the rotating member 49 drives the connecting member 47 to move up and down, thereby realizing the lifting of the lifting frame 43. Optionally, an articulated seat is provided on the lifting frame 43, and the connecting member 47 is hinged to the articulated seat. Further A hinge shaft is provided on the rotating member 49, and the hinge shaft is perpendicular to the circumferential surface on which the rotating member 49 rotates. A hinge hole is provided on the connecting member 47, and the hinge shaft is hinged in the hinge hole. Optionally, the driving member is a driving motor 201, and the power output end of the driving motor 201 drives the rotating member 49 to rotate. In other embodiments, when the second driving component 200 is not linked with the intermittent feeding component 500, the second driving component 200 can also use a lifting cylinder to directly drive the lifting frame 43 to lift, and the lifting cylinder can be installed on the frame 10, and the piston rod of the lifting cylinder is directly connected to the lifting frame 43.

[0051] In this embodiment, if Figure 2 As shown, a linear motion pair is also installed on the frame 10, and the lifting frame 43 is connected to the linear motion pair. The lifting frame 43 moves linearly under the action of the linear motion pair. The linear motion pair ensures the straightness of the movement of the lifting frame 43, thereby ensuring the stability of the pressing area of ​​the pressing piece 41, which makes it easier for the pressing piece 41 to press the material.

[0052] In this embodiment, if Figure 2 As shown, the linear motion pair includes a crossbeam 44, and a through hole for a connecting member 47 to pass through is opened on the crossbeam 44. The frame 10 is a gantry frame, so there is a cavity between the top plate and the side plate of the frame 10, and the pressing member 41 is in the cavity. The second driving assembly 200 is installed on the top plate of the gantry frame, and the crossbeam 44 is installed across the frame 10, and the crossbeam 44 is located below the gantry frame. A linear bearing 45 is installed on the crossbeam 44, and a guide shaft 46 is installed on the top of the lifting frame 43. The guide shaft 46 and the linear bearing 45 are slidably matched. The straightness of the movement of the lifting frame 43 is guaranteed by the cooperation between the guide shaft 46 and the linear bearing 45. In other embodiments, the linear motion pair can also use a linear slider and a linear slide rail. Optionally, the linear slide rail is installed on the inner side of the side plate of the frame 10, and the linear slider is installed on the lifting frame 43. The linear slide rail can also be installed on the outer side of the crossbeam 44, and the linear slider is installed on the lifting frame 43, and then the linear slider and the linear slide rail are slidably matched.

[0053] In this embodiment, if Figure 2 and Figure 3As shown, the intermittent feeding assembly 500 includes an overrunning clutch 51 and a swinging member 52. The overrunning clutch 51 can be selected as a ratchet overrunning clutch or a roller overrunning clutch. The overrunning clutch 51 is installed at one end of the swinging member 52, and the overrunning clutch 51 is mounted on the active roller of the conveying device 50. The other end of the swinging member 52 is connected to a third driving device, and the third driving device drives the swinging member 52 to swing back and forth. When the third driving device is working, the swinging member 52 swings back and forth, and then the overrunning clutch 51 drives the active roller to rotate intermittently, thereby realizing intermittent feeding of the conveying device 50. Preferably, the overrunning clutch 51 uses a roller overrunning clutch. In this embodiment, the third driving device includes a power source, and a turntable is installed at the output end of the power source. A first hinged rod 55 is eccentrically hinged on the turntable, and a lever 54 is hinged on the other end of the first hinged rod 55. The lever 54 is rotatably installed on the frame 10, and the other end of the lever 54 is hinged to a second hinged rod 53, and the second hinged rod 53 is hinged to the swinging member 52. Then, when the power source drives the turntable to rotate, the swinging member 52 swings within a certain range. Since the pressing member 41 presses the material by its own gravity, there is a period of time during the downward and upward movement of the lifting frame 43 so that the pressing member 41 and the lifting frame 43 do not move synchronously. Since the overrunning clutch 51 is provided, when the swinging member 52 swings down, the conveying device 50 conveys the material forward, and when the swinging member 52 swings up, the conveying device 50 stops working. Therefore, when the swinging member 52 swings up, the pressing member 41 presses the material. The material piece 41 presses the material, and when the swing piece 52 is about to swing to the upper stroke, the material pressing piece 41 moves upward with the lifting rod, thereby making the material pressing piece 41 separate from the material. In other words, when the swing piece 52 swings to the upper stroke, the material pressing piece 41 has been separated from the material. Similarly, when the swing piece 52 starts to swing upward, the material pressing piece 41 starts to press the material. Since the lifting frame 43 and the swing piece 52 work continuously, the continuity of the intermittent feeding device can be ensured by adjusting the length of the sliding piece 42.

[0054] In this embodiment, if Figure 4 and Figure 5As shown, the knife assembly 300 includes a cross slide rail, and the cross slide rail includes a horizontal slide rail 305, a horizontal slider 304, a vertical slide rail 302 and a mounting plate 301. Vertical sliders 303 are installed on both sides of the mounting frame, and a vertical slide groove is provided on the vertical slider 303. The vertical slide rail 302 is installed on the inner side of the mounting plate 301, and the vertical slide rail 302 is slidably matched with the vertical slide groove. The vertical slide rail 302 is slidably matched with the vertical slide groove, so as to ensure that the mounting frame makes a linear motion in the vertical direction relative to the mounting plate 301. A horizontal slider 304 is installed on the outer side of the mounting plate 301, and a horizontal slide groove is provided on the horizontal slider 304. The horizontal slider 304 is installed on the inner side of the frame 10, and the horizontal slider 304 is slidably matched with the horizontal slide groove. When the mounting plate 301 is subjected to a horizontal force , the mounting plate 301 can move horizontally. Further, a movable plate 308 is installed on the mounting plate 301, and a fixed plate 306 is also installed on the inner side of the frame 10. The movable plate 308 and the fixed plate 306 are connected by a plurality of guide shafts 46, and a return spring 307 is installed on the guide shaft 46 between the movable plate 308 and the fixed plate 306. The movable plate 308 is located in front of the fixed plate 306. A roller 311 is also installed on the front side wall of the mounting plate 301. A driven shaft 310 is also installed on the frame 10. The driven shaft 310 is driven by a driving device, and the driving device is installed on the frame 10. Cams 309 corresponding to the rollers 311 are installed at both ends of the driven shaft 310. The rollers 311 always slide along the track of the cams 309 under the action of the return springs 307. Figure 6As shown, the cam 309 has a first arc 313 and a second arc 314, the first arc 313 and the second arc 314 have a smooth transition, the radius of the first arc 313 is greater than the radius of the second arc 314, when the roller 311 is located on the first arc 313, the shredder assembly 100 moves downward and completes shredding of the material, when the roller 311 is separated from the first arc 313, the shredder assembly 100 is away from the cutting surface of the material, and after the roller 311 is located on the second arc 314, the shredder assembly 100 is reset, so when the material is cut, when the shredder moves downward, at this time, when the roller 311 is located on the first arc 313, the reset spring 307 is in a compressed state, the shredder moves downward and completes shredding of the material, and then the roller 311 is separated from the first arc 313 and moves to the second arc The arc 314 moves, at this time, the reset spring 307 applies a horizontal thrust to the movable plate 308, so that the mounting plate 301 moves forward, and at the same time, the mounting plate 301 moves upward under the action of the driving assembly 200, so the shaving assembly 100 has horizontal and vertical movements during the resetting process, and its movement trajectory is similar to the movement trajectory of a circular arc. Therefore, during the entire cutting and resetting process, the moving trajectory of the shaving assembly 100 is similar to a "D" shape, so the shaving knife can detach from the cutting surface after completing the cutting of the material, and during the resetting process, it no longer contacts the cutting surface, and thus does not cause feed debris, thereby ensuring the feed cutting quality, greatly reducing feed debris, and ensuring the regularity of the feed shape and the requirements of the silkworm for feed feeding.

[0055] In this embodiment, if Figure 5 As shown, a support frame 312 is provided on the front side wall of the mounting plate 301, and the roller 311 is installed on the support frame 312. The support frame 312 is a tripod, and the roller 311 is rotatably installed on the tripod. Preferably, the roller 311 adopts a ball bearing. When installing, a rotating shaft can be passed through the tripod.

[0056] In this embodiment, in order to save space, the entire cutting device is made simpler. Figure 1 and Figure 2As shown, the intermittent feeding assembly 500, the pressing assembly 400, the shaving assembly 100 and the knife assembly 300 share a power source, which is the driving motor 201 of the shaving assembly 100. The transmission main shaft 202 of the shaving assembly 100 and the driven shaft 310 of the knife assembly 300 are driven by a chain. The second driving assembly 200 of the pressing assembly 400 also includes a driven rotating shaft 48. The transmission main shaft 202 and the driven rotating shaft 48 are driven by a chain. Both ends of the driven rotating shaft 48 are provided with rotating parts 49, one of which is eccentrically hinged on the rotating part 49. The other rotating part 49 is a turntable of the third driving assembly 200. That is to say, when the driving motor 201 is working, the driving motor 201 transmits power to the transmission shaft 48. On the driving spindle 202, the transmission spindle 202 transmits the power to the driven rotating shaft 48 and the driven shaft 310 respectively through chain transmission. When the driven rotating shaft 48 rotates, the rotating member 49 is rotated. One of the rotating members 49 drives the lifting frame 43 to rise and fall through the connecting member 47, and the other rotating member 49 drives the swinging member 52 to swing back and forth through the first hinge rod 55, the lever 54, and the second hinge rod 53. The driven shaft 310 rotates, thereby causing the cam 309 to rotate, so that the roller 311 continuously rolls from the first arc 313 to the second arc 314, and then rolls from the second arc 314 to the first arc 313. In other words, the knife assembly 300 is continuously switched back and forth between the cutting station and the knife retracting station.

[0057] In this embodiment, taking the cutting of feed blocks as an example, the working process of the feeding device is described. The feed blocks are placed on the conveying device 50, and then the motor 201 is driven to work, so that the transmission main shaft 202, the driven shaft 48 and the driven shaft 310 are all rotated, and the driven shaft 48 drives the turntable and the rotating member 49 to rotate. After the turntable rotates, the swing member 52 swings back and forth. When the swing member 52 swings downward, the conveying device 50 conveys the feed blocks forward. At this time, the rotating member 49 drives the lifting frame 43 to rise through the connecting member 47, and the pressing member 41 is located above the material. At the same time, the shredder assembly 100 is in the return state, and the knife assembly 300 is in the knife retracting position, so that the shredder assembly 100 is released. When the grater 41 is pressed down by its own weight, the grater cuts the feed block into strips or filaments. When the grater cuts, the roller 311 moves from the first arc 313 to the second arc 314. At this time, the grater cuts forward under the action of the reset spring 307, thereby making the grater cutter separate from the cutting surface of the feed block. Then, the grater assembly 100 is reset under the action of the first driving assembly 200. At the same time, the grater 52 swings downward again, and then the above-mentioned actions are repeated to realize continuous cutting of the feed block.

[0058] Embodiment 2:

[0059] The intermittent feeding assembly 500, the frame 10, the pressing assembly 400, and the grating knife of this embodiment are the same as those of the first embodiment, except that the structure of the knife assembly 300 is different, thereby changing the lifting method of the grating knife. Fig.11 and Fig.12As shown, the cutter assembly 300 includes a cross slide and a Hawken linkage mechanism, the horizontal slide 305 of the cross slide is installed on the inner side of the frame 10, the vertical slide 302 of the cross slide is installed on the outer side wall of the shaving assembly 100, the power input end of the Hawken linkage mechanism is eccentrically hinged to the flywheel 203, and the power output end of the Hawken linkage mechanism is hinged to the mounting frame. In this embodiment, the cross slide includes a horizontal slide 305, a horizontal slider 304, a vertical slide 302 and a mounting plate 301, and vertical sliders 303 are installed on both sides of the mounting frame. A vertical slide groove is opened on the vertical slide 303, and the vertical slide 302 is installed on the inner side of the mounting plate 301, and the vertical slide 302 is slidably matched with the vertical slide groove. The rail 302 slides in cooperation with the vertical slide groove, thereby ensuring that the mounting frame makes a linear motion in the vertical direction relative to the mounting plate 301. A horizontal slider 304 is installed on the outer side of the mounting plate 301, and a horizontal slide groove is provided on the horizontal slider 304. The horizontal slider 304 is installed on the inner side of the frame 10, and the horizontal slider 304 slides in cooperation with the horizontal slide groove. When the mounting plate 301 is subjected to a horizontal force, the mounting plate 301 can move horizontally. Further, the Hawken linkage mechanism includes a first link 321, a second link and a fixed shaft 323. One end of the first link 321 is eccentrically hinged to the flywheel 203, and the other end of the first link 321 is hinged to the shredder assembly 100. One end of the second link 322 is rotatably mounted on the fixed shaft. On the fixed shaft 323, the other end of the second connecting rod 322 is hinged to the middle part of the first connecting rod 321, and both ends of the fixed shaft 323 are fixedly mounted on the frame 10. The moving trajectory of the Hawken connecting rod mechanism has a straight segment and an arc segment, and the arc segment and the straight segment form a closed ring. In this embodiment, when the grater cuts the material downward, the moving trajectory of the Hawken connecting rod mechanism is a straight line movement, and when the grater cuts and is in the process of resetting, the moving trajectory of the Hawken connecting rod mechanism is an arc movement. Therefore, when the driving motor 201 is working, it drives the transmission main shaft 202 to rotate, thereby causing the first connecting rod 321 to rotate. Since the first connecting rod 321 and the flywheel 203 are eccentrically hinged, the first connecting rod 3 The moving trajectory of 21 has a high point and a low point. When the first connecting rod 321 moves from the high point to the low point, the knife assembly 300 is in the cutting position, and the grater moves vertically downward under the action of the Hawken connecting rod mechanism, thereby completing the cutting of the material. When the first connecting rod 321 moves to the low point, the grater completes the cutting of the material, and then when the first connecting rod 321 moves from the low point to the high point, the knife assembly 300 is in the retracting position, and the grater moves in an arc under the action of the Hawken connecting rod mechanism, thereby preventing the grating assembly 100 from contacting the material during the resetting process, and thereby preventing the grating assembly 100 from contacting the cutting surface of the material again during the return stroke, thereby avoiding the generation of a large amount of debris, thereby ensuring the cutting quality.

[0060] In this embodiment, if Fig.11As shown, the intermittent feeding assembly 500, the pressing assembly 400, and the shaving assembly 100 share a power source, which is the driving motor 201 of the shaving assembly 100. The second driving assembly 200 of the pressing assembly 400 also includes a driven shaft 48. The transmission main shaft 202 of the shaving assembly 100 and the driven shaft 48 are driven by a chain. Both ends of the driven shaft 48 are provided with rotating parts 49, one of which is eccentrically hinged with a connecting part 47, and the other rotating part 49 is a turntable of the third driving assembly 200. When the driving motor 201 is working, the driving motor 201 transmits power to the transmission main shaft 202. 2, the transmission main shaft 202 transmits power to the driven shaft 48 through chain transmission. When the driven shaft 48 rotates, the rotating member 49 is rotated. One rotating member 49 drives the lifting frame 43 to rise and fall through the connecting member 47, and the other rotating member 49 drives the swing member 52 to swing back and forth through the first hinge rod 55, the lever 54 and the second hinge rod 53. After the transmission main shaft 202 rotates, the shredder assembly 100 vertically cuts the feed block under the action of the Hawken linkage mechanism. After cutting the feed block, the knife assembly 300 is in the knife retracting position, and the shredder moves in an arc under the action of the Hawken linkage mechanism.
