[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] After the grater was installed, the inventor observed the cut surface of the feed block after the grater completed cutting the feed block and found that the cut surface of the feed block did not have a regular cutting trajectory, and some areas were protruding.

After long-term research, the inventor found that because the grater was a thin plate structure and the length and width of the grater were both wide, its structural strength was not high. During installation, the grater was easily deformed. Moreover, when cutting the feed block, the feed block had an axial reaction force on the cutter. After long-term use, the grater was prone to slight inward deformation, which resulted in an uneven cutting trajectory of the feed block. Utility Model Content

[0028] like Figure 4 and Figure 5 As shown, a grating device includes a thin plate grating knife, a mounting frame 15 and a driving mechanism for driving the mounting frame 15 to rise and fall. The thin plate grating knife is installed on the mounting frame 15, and the driving mechanism is installed on the frame 17. When the driving mechanism works, it drives the mounting frame 15 to rise and fall, so that the thin plate grating knife reciprocates in the lifting direction. In this embodiment, the thin plate grating knife reciprocates in the vertical direction. During the reciprocating motion, the thin plate grating knife cuts the material into filaments or strips.
[0029] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, the thin plate grater comprises 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 at the rear 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 outward, and the plate body bent outward of the folding plate 5 is a flange plate 4, and a plurality of mounting holes are opened on the flange plate 4. Therefore, when the grating board 1 is placed horizontally, the thin plate grater presents a "J"-shaped structure, and further The slicing board 1 is provided with a plurality of knives 2 that arch forward, 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 wires. The slicing board 1 is also provided with a cutting channel 3 corresponding to the knives 2, and the cutting channel 3 is connected to the arch cavity of the knives 2. When the thin plate slicing knife moves downward, the cutting edge of the knives 2 cuts the material, and the cut material is in the shape of wires or strips, and finally enters the cutting channel 3. , discharged from the rear side of the grating board 1. The thin plate grating knife 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 front degree 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. Moreover, the stamped thin plate grating knife has a "J"-shaped structure, which increases the structural strength of the thin plate grating knife and can ensure the flatness of the grating board 1 of the thin plate grating knife. At the same time, the grating board 1 is in front of 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 thin plate 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 thin plate grating knife in cutting the material.
[0030] In this embodiment, if Figure 1 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 3 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 the material cutting amount and the material feed amount.
[0031] In this embodiment, if Figure 4As shown, the mounting frame 15 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 from each other, the flange plates 4 of the folding plate 5 are respectively mounted on the corresponding mounting transverse plates 22, and the front end surface of the shaving board 1 protrudes from the front end surface of the mounting transverse plate 22, so the tool 2 on the shaving board 1 is located in front of the mounting transverse plate 22, so that the mounting frame 15 will not affect the cutting of the material by the tool 2 during the lifting process, and the mounting frame 15 will not contact the material, thereby ensuring the reliability of the 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.
[0032] In this embodiment, if Figure 5 As shown, the frame 17 is a gantry, the gantry has a cavity, the mounting frame 15 is located in the cavity of the gantry, and a linear motion pair 16 is installed between the inner side of the side plate of the gantry and the mounting frame 15. The linear motion pair 16 can ensure the straightness of the movement of the mounting frame 15, thereby ensuring the straightness of the movement of the thin plate grating knife and ensuring the cutting quality of the material.
[0033] In this embodiment, if Figure 5 As shown, the linear moving pair 16 includes a linear guide rail and a slider 24. The linear guide rail is installed on the inner side of the side plate of the frame 17, and the slider 24 is installed on the outer wall of the mounting side plate 21. A slide groove is opened on the slider 24, and the linear guide rail slides in the slide groove. The slide groove can be set to be a rectangular groove or a dovetail groove, and the shape of the linear slide rail 25 changes with the shape of the slide groove. In other embodiments, the linear moving pair 16 can also be a guide shaft and a linear bearing. The guide shaft is vertically installed on the top of the mounting frame 15, and the linear bearing is installed on the top of the frame 17. The guide shaft is slidably installed in the linear bearing.
[0034] In this embodiment, if Figure 4 and Figure 5As shown, the driving mechanism includes a driving motor 11 and a transmission spindle 12. The driving motor 11 is installed on a frame 17. The transmission spindle 12 is rotatably installed on the frame 17. The driving motor 11 drives the transmission spindle 12 to rotate. Flywheels 13 are arranged at both ends of the transmission spindle 12. A connecting rod 14 is eccentrically hinged on the flywheel 13. The other end of the connecting rod 14 is hinged to the mounting side plate 21. When the driving motor 11 is working, the transmission spindle 12 rotates, thereby causing the flywheel 13 to rotate. Since the connecting rod 14 and the flywheel 13 are eccentrically hinged, the moving trajectory of the connecting rod 14 has a high point and a low point. When the connecting rod 14 moves from a high point to a low point, the mounting frame 15 moves vertically downward under the guiding action of the linear moving pair 16, and when the connecting rod 14 moves from a low point to a high point, the mounting frame 15 moves vertically upward under the guidance of the linear moving pair 16, so every time the flywheel 13 rotates once, the mounting frame 15 completes a lifting, and the grater completes a cutting of the material. In this embodiment, a hinged portion 23 is provided at the rear end of the mounting cross plate 22, and the connecting rod 14 is hinged to the hinged portion 23. The hinged portion 23 is a semicircular structure, and a hinge hole is provided on the hinged portion 23, and a hinge shaft is passed through the hinge hole. A horn fork 26 is provided at the bottom of the connecting rod 14, and the hinge shaft can be rotatably installed in the horn fork 26, and the hinged portion 23 can rotate in the horn fork 26, and a hinge shaft is provided on the flywheel 13, and a hinge hole is provided at the top of the connecting rod 14, 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.
[0035] The driving mechanism is not limited to the above-mentioned driving mechanism. In other embodiments, the driving mechanism can also simply adopt a cylinder, and the telescopic rod of the cylinder is connected to the mounting frame 15, or the driving mechanism can also adopt other crank rocker mechanisms that realize linear reciprocating motion through circular motion.
[0036] Taking cutting feed blocks as an example, the working process of the shredder device is described in detail. The feed block moves to the bottom of the thin-plate shredder under the action of the conveying mechanism, and the driving motor 11 works, thereby driving the transmission main shaft 12 to rotate, and the connecting rod 14 moves from a high point to a low point. The mounting frame 15 moves vertically downward under the guidance of the linear moving pair 16. At this time, the thin-plate shredder moves downward. When the cutter 2 contacts the feed block, the thin-plate shredder continues to move downward, and the cutter 2 cuts the feed block, and then cuts the feed block into strips. The cut feed block is discharged from the cutting channel 3. When the connecting rod 14 moves to the low point, the cutter 2 completes one cut of the feed block. Of course, during the cutting process, the conveying mechanism stops working, and then the connecting rod 14 moves from the low point to the high point, and the cutter 2 is reset.
[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
