Description

Technical Field

[0001] The utility model relates to a feed block cutting technology, in particular to a feed cutting 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

[0033] Embodiment 1:

[0034] like Figure 1 As shown, a material cutting device includes a frame, a shredder assembly 100 and a driving assembly 200. The driving assembly 200 is installed on the frame, and the driving assembly 200 drives the shredder assembly 100 to rise and fall. The frame is also installed with a knife assembly 300. After the shredder assembly 100 completes the cutting action on the material and during the resetting process of the shredder assembly 100, the knife assembly 300 pushes the shredder assembly 100 away from the cutting surface of the material, and the driving assembly 200 works, thereby driving the shredder assembly 100 to rise and fall. During the downward process of the shredder assembly 100, the material is cut, and then the shredder assembly 100 goes up, that is, the shredder assembly 100 is reset. During the resetting process of the shredder assembly 100, the knife assembly 300 pushes the shredder assembly 100 away from the cutting surface of the material, so that the shredder assembly 100 does not contact the material during the resetting process, and the shredder assembly 100 does not contact the cutting surface of the material again during the return process, thereby avoiding the generation of a large amount of debris, thereby ensuring the cutting quality.

[0035] In this embodiment, if Figure 6 , Figure 7 and Figure 8As shown, the shaving assembly 100 includes a shaving blade and a mounting frame, the shaving blade is mounted on the mounting frame, and the mounting frame is connected to the power output end of the driving assembly 200. Further, the shaving blade includes a shaving board 1 and a folding plate 5, the upper and lower edges of the shaving board 1 are connected with the folding plate 5, the folding plate 5 is located on the front side of the shaving board 1, and the angle between the folding plate 5 and the shaving 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 by the folding plate 5 is a flange plate 4, and the flange plate 4 A plurality of mounting holes are provided on the shaving board 1, so when the shaving board 1 is placed horizontally, the shaving knife is in a "J"-shaped structure. Further, a plurality of knives 2 that arch backward are provided on the shaving 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 a strip or wire shape. A cutting channel 3 corresponding to the knives 2 is also provided on the shaving board 1, and the cutting channel 3 is connected to the arch cavity of the knives 2. When the shaving knife moves downward, the cutting edge of the knives 2 cuts the material. After cutting, the cut material is in the form of wire 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 tool 2 gradually shrinks from the cutting edge position to the grating board 1, so the tool 2 can increase the structural strength of the grating board 1, 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 grating knife after stamping has a "J"-shaped structure, which increases the structural strength of the grating knife and can ensure the flatness of the grating board 1 of the grating 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 filament 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 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.

[0036] In this embodiment, in the left-right direction, the knives 2 are evenly distributed at equal intervals, and in the up-down direction, two adjacent rows of knives 2 are staggered, and on the vertical projection plane, as shown in FIG. Figure 7 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.

[0037] In this embodiment, if Figure 5As 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.

[0038] In this embodiment, if Figure 2 As shown, the driving mechanism includes a driving motor 201 and a transmission spindle 202. The driving motor 201 is installed on the frame, and the transmission spindle 202 is rotatably installed on the frame. The frame 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 spindle 202 to rotate. Flywheels 203 are provided at both ends of the transmission spindle 202. A connecting rod 204 is eccentrically hinged on the flywheel 203, and 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 spindle 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 drives the shredder down. 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.

[0039] In this embodiment, if Figure 2 and Figure 3As 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 slide rails 303 are installed on both sides of the mounting frame, and a vertical slide groove is provided on the vertical slide rail 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, and the horizontal slider 304 is slidably matched with the horizontal slide groove. When the mounting plate 301 is subjected to horizontal When a force is applied in the direction of the axis, the mounting plate 301 can move horizontally. Furthermore, 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. The movable plate 308 and the fixed plate 306 are connected by a plurality of guide shafts, and a return spring 314 is installed on the guide shaft between the movable plate 308 and the fixed plate 306. The movable plate 308 is located in front of the fixed plate 306, and 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. The driven shaft 310 is driven by a driving device, and the driving device is installed on the frame. 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 314. Figure 4As 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 314 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 314 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.

[0040] In this embodiment, if Figure 2 and Figure 3 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.

[0041] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the driving device of the knife assembly 300 shares a motor with the driving assembly 200, that is, the driving device is the driving motor 201, and the transmission main shaft 202 and the driven shaft 310 are driven by a chain. Sprockets are installed in the middle of the transmission main shaft 202 and the driven shaft 310, and the two sprockets are connected by a chain.

[0042] The working process of the utility model is as follows: the driving motor 201 works, so that the transmission main shaft 202 rotates, and the transmission main shaft 202 transmits power to the driven shaft 310 through chain transmission, thereby causing the driven shaft 310 to rotate. After the transmission main shaft 202 rotates, the flywheel 203 rotates with the transmission main shaft 202. When the connecting rod 204 moves from a high point to a low point, the mounting frame moves vertically downward under the guidance of the vertical slide rail 302 and the vertical slide groove. At this time, the thin plate grating knife moves downward, and the roller 311 enters the first arc 313. When the cutter 22 contacts the feed block, the grating knife continues to move downward, and the cutter 2 cuts the feed block, thereby cutting the feed block into strips. The cut feed block is discharged from the cutting channel 3. When the connecting rod 204 moves to a low point, the cutter 2 completes one cut of the feed block. After the feed block is cut, the roller 311 disengages from the first arc. 313, under the action of the reset spring 314, the grater moves away from the cutting surface of the feed block, and then the connecting rod 204 moves from the low point to the high point, and the grater moves upward. With the rotation of the cam 309, the roller 311 rolls from the first arc 313 to the second arc 314. When the roller 311 moves to the middle area of ​​the second arc 314, the grater is reset, and then the connecting rod 204 moves from the high point to the low point again. With the rotation of the roller 311, the roller 311 rolls from the second arc 314 to the first arc 313. During the rolling process of the roller 311, the grater gradually approaches the feed block in the front and rear directions. When the roller 311 is just located on the first arc 313, the grater is directly above the cutting surface of the feed block. With the movement of the roller 311 from the high point to the low point, the grater moves downward and completes the cutting of the feed block again. Then the above actions are repeated to complete the continuous cutting of the feed block.

[0043] Embodiment 2:

[0044] like Fig. 9 As shown, a material cutting device includes a frame, a shredder assembly 100 and a driving assembly 200. The driving assembly 200 is installed on the frame, and the driving assembly 200 drives the shredder assembly 100 to rise and fall. The frame is also installed with a knife assembly 300. After the shredder assembly 100 completes the cutting action on the material and during the resetting process of the shredder assembly 100, the knife assembly 300 pushes the shredder assembly 100 away from the cutting surface of the material, and the driving assembly 200 works, thereby driving the shredder assembly 100 to rise and fall. During the downward process of the shredder assembly 100, the material is cut, and then the shredder assembly 100 goes up, that is, the shredder assembly 100 is reset. During the resetting process of the shredder assembly 100, the knife assembly 300 pushes the shredder assembly 100 away from the cutting surface of the material, so that the shredder assembly 100 does not contact the material during the resetting process, and the shredder assembly 100 does not contact the cutting surface of the material again during the return process, thereby avoiding the generation of a large amount of debris, thereby ensuring the cutting quality.

[0045] In this embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, the shaving assembly 100 includes a shaving blade and a mounting frame, the shaving blade is mounted on the mounting frame, and the mounting frame is connected to the power output end of the driving assembly 200. Further, the shaving blade includes a shaving board 1 and a folding plate 5, the upper and lower edges of the shaving board 1 are connected with the folding plate 5, the folding plate 5 is located on the front side of the shaving board 1, and the angle between the folding plate 5 and the shaving 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 by the folding plate 5 is a flange plate 4, and the flange plate 4 A plurality of mounting holes are provided on the shaving board 1, so when the shaving board 1 is placed horizontally, the shaving knife is in a "J"-shaped structure. Further, a plurality of knives 2 that arch backward are provided on the shaving 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 a strip or wire shape. A cutting channel 3 corresponding to the knives 2 is also provided on the shaving board 1, and the cutting channel 3 is connected to the arch cavity of the knives 2. When the shaving knife moves downward, the cutting edge of the knives 2 cuts the material. After cutting, the cut material is in the form of wire 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 tool 2 gradually shrinks from the cutting edge position to the grating board 1, so the tool 2 can increase the structural strength of the grating board 1, 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 grating knife after stamping has a "J"-shaped structure, which increases the structural strength of the grating knife and can ensure the flatness of the grating board 1 of the grating 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 filament 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 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.

[0046] In this embodiment, if Figure 6 As 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. Figure 7 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.

[0047] In this embodiment, if Fig.10As 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.

[0048] In this embodiment, if Fig. 9 and Fig.10 As shown, the driving mechanism includes a driving motor 201 and a transmission spindle 202. The driving motor 201 is installed on a frame, and the transmission spindle 202 is rotatably installed on the frame. The frame is a gantry, and the gantry has a cavity. The mounting frame is located in the cavity of the gantry. The driving motor 201 drives the transmission spindle 202 to rotate, and flywheels 203 are provided at both ends of the transmission spindle 202.

[0049] In this embodiment, if Fig.10As 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, 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, vertical slides 303 are installed on both sides of the mounting frame, a vertical slide groove is provided on the vertical slide 303, the vertical slide 302 is installed on the inner side of the mounting plate 301, and the vertical slide 302 and the vertical slide groove are slidably matched. The vertical slide rail 302 slides with the vertical slide groove 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. A horizontal slide groove is provided on the horizontal slider 304. The horizontal slider 304 is installed on the inner side of the frame, and the horizontal slider 304 slides 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 connecting rod mechanism includes a first connecting rod 321, a second connecting rod and a fixed shaft 323. One end of the first connecting rod 321 is eccentrically hinged to the flywheel 203, and the other end of the first connecting rod 321 is hinged to the shredder assembly 100. One end of the rod 322 is rotatably mounted on the fixed shaft 323, the other end of the second connecting rod 322 is hinged to the middle of the first connecting rod 321, and both ends of the fixed shaft 323 are fixedly mounted on the frame. 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 the material 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 32 1 is eccentrically hinged with the flywheel 203, so that the moving trajectory of the first connecting rod 321 has a high point and a low point. When the first connecting rod 321 moves from the high point to the low point, 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. Then, when the first connecting rod 321 moves from the low point to the high point, the grater moves in an arc under the action of the Hawken connecting rod mechanism, thereby preventing the grater assembly 100 from contacting the material during the resetting process, and thereby preventing the grater assembly 100 from contacting the material cutting surface again during the return stroke, thereby avoiding the generation of a large amount of debris, thereby ensuring the cutting quality.
