[0002] Chopping equipment can shred materials such as various nuts and seeds. Existing chopping equipment is fixed and complex in structure, difficult to adjust, and inconvenient and time-consuming to clean. It not only fails to shred materials quickly, but also produces unevenly shredded materials with inconsistent particle sizes, leading to prolonged downtime and reduced production efficiency. Therefore, a chopping device is urgently needed to solve these problems. Utility Model Content

[0003] To address the technical problems of existing cutting equipment that cannot quickly shred materials, and that the shredded materials are unevenly shredded, have inconsistent particle sizes, and are inconvenient to clean, this utility model provides a cutting device with a simple structure that achieves uniform material shredding with basically consistent particle size. At the same time, the cutting blade is easy to clean, reducing equipment downtime.

[0004] This utility model provides a cutting device, including a frame and a cutting mechanism and a driving mechanism mounted on the frame. The cutting mechanism includes a cutting frame movably mounted on the frame and multiple cutting blades detachably mounted on the cutting frame. A conveyor belt is rotatably mounted on the frame, and the multiple cutting blades are located above the conveyor belt. The driving mechanism includes a drive shaft and two connecting rods. The drive shaft is rotatably mounted on the frame and located below the conveyor belt. Both ends of each connecting rod are rotatably connected to the drive shaft and the cutting frame, respectively. The two connecting rods are located at both ends of the conveyor belt. When the drive shaft rotates, it drives the connecting rods to move up and down. The connecting rods then drive the cutting frame to move up and down, and ultimately the multiple cutting blades move up and down. When the conveyor belt carries the material to below the multiple cutting blades, the multiple cutting blades sequentially cut the material.

[0005] Furthermore, the cutter holder includes two vertical plates and a plurality of horizontal plates evenly arranged between the two vertical plates, and each of the horizontal plates can be detachably provided with at least one and at most two cutting blades.

[0006] Furthermore, each of the horizontal plates is evenly provided with multiple screw holes, and multiple screw rods are provided through the multiple screw holes in the same row of the multiple horizontal plates. Each of the cutting blades is evenly provided with multiple strip grooves, and multiple screw rods are respectively inserted into the multiple strip grooves on the cutting blades. The cutting blades are locked to the horizontal plates by multiple locking nuts and screw rods.

[0007] Furthermore, the frame is provided with two guide sections, each guide section including two tracks arranged opposite to each other on the frame. Each vertical plate is provided with a blade holder shaft, and a slider is fixedly mounted on the blade holder shaft. The slider is engaged between the two tracks of the guide section and moves along the height direction of the tracks. The slider moves up and down between the two tracks of the guide section, thereby driving the cutter holder and multiple cutter blades to move up and down.

[0008] Furthermore, each of the connecting rods is threaded with an upper bearing seat and a lower bearing seat at both ends, and the end of the tool holder shaft is fixedly connected to the upper bearing in the upper bearing seat. The upper bearing seat is located outside the slider. Eccentric sleeves are fixedly provided at both ends of the drive shaft, and the end of the drive shaft is fixedly connected to the lower bearing in the lower bearing seat through the eccentric sleeves.

[0009] Furthermore, the upper bearing seat has a first connecting groove, the upper part of the connecting rod passes through the first connecting groove and is threadedly connected thereto, the upper part of the connecting rod is threadedly connected to a positive nut, and the positive nut contacts or separates from the upper bearing seat; the lower bearing seat has a transition rod threadedly connected thereto, the transition rod has a transition connecting groove, the lower part of the connecting rod passes through the transition connecting groove and is threadedly connected thereto, the lower part of the connecting rod is threadedly connected to a negative nut, and the negative nut contacts or separates from the transition rod.

[0010] Furthermore, each connecting rod has a positive thread and a negative thread at its upper and lower parts, respectively, with the threads in opposite directions. The inner wall of the first connecting groove has a first internal thread matching the positive thread, and the inner wall of the transition connecting groove has a transition internal thread matching the negative thread. The upper part of the connecting rod is fixedly connected to the upper bearing seat via the positive thread and the first internal thread; the lower part of the connecting rod is fixedly connected to the transition rod via the negative thread and the transition internal thread.

[0011] Furthermore, the lower bearing seat has a second connecting groove, and the inner wall of the second connecting groove has a second internal thread. The outer wall of the transition rod has an external thread that matches the second internal thread. The lower part of the transition rod passes through the second connecting groove and is threadedly connected to it. The lower bearing seat and the transition rod are fixedly connected through the external thread and the second internal thread.

[0012] Furthermore, two support bearing seats are arranged opposite each other on the frame. The two ends of the drive shaft pass through the support bearings in the two support bearing seats and are fixedly connected to them. The two eccentric sleeves are located on the outside of the two support bearing seats. When the drive shaft rotates, the drive shaft and the support bearings in the support bearing seats rotate relative to the two support bearing seats.

[0013] Furthermore, the drive mechanism also includes a drive motor fixedly mounted on the frame. The output shaft of the drive motor is fixedly connected to the drive pulley and can drive it to rotate. A driven pulley is fixedly mounted in the middle of the drive shaft, and a belt is sleeved between the drive pulley and the driven pulley. When the drive motor starts, it drives the drive pulley to rotate, which in turn drives the driven pulley and the belt to rotate, thus rotating the drive shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model's cutting device features a rotating drive shaft that drives a connecting rod to move up and down. This connecting rod, in turn, moves the cutting blade holder up and down, ultimately causing multiple cutting blades to move vertically. When the conveyor belt carries material to beneath these blades, they sequentially shred the material, resulting in uniform and rapid shredding of the material into particles of roughly the same size. Furthermore, the cutting blades are detachable, allowing for quick and easy cleaning after prolonged use. This reduces downtime, increases production efficiency, and lowers labor and time costs.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-6 As shown, a cutting device includes a frame 1 and a cutting mechanism 2 and a drive mechanism 3 mounted on the frame 1. The cutting mechanism 2 includes a cutting holder 21 movably mounted on the frame 1 and multiple cutting blades 22 detachably mounted on the cutting holder 21. Generally, to accommodate the uniform chopping of different materials, the cutting blades 22 are adjusted to a suitable position and fixed on the cutting holder 21. A conveyor belt 4 is rotatably mounted on the frame 1 for conveying materials (e.g., nuts). The materials are evenly spread on the conveyor belt 4, and the multiple cutting blades 22 are located above the conveyor belt 4. The drive mechanism 3 includes a drive shaft 31 and two connecting rods 32. The drive shaft 31 is rotatably mounted on the frame 1 and located below the conveyor belt 4. Both ends of each connecting rod 32 are rotatably connected to the drive shaft 31 and the cutting holder 21, respectively. The two connecting rods 32 are located at both ends of the conveyor belt 4.

[0026] The working process of the cutting equipment: The drive shaft 31 rotates, driving the connecting rod 32 to move up and down. The connecting rod 32 then drives the cutting blade holder 21 to move up and down, ultimately causing multiple cutting blades 22 to move up and down. When the conveyor belt 4 carries the material to below the multiple cutting blades 22, the multiple cutting blades 22 sequentially cut the material, achieving uniform and rapid cutting. The chopped material particles are basically the same size, maintaining uniformity. The overall structure of the cutting equipment is simple, and the cutting blades 22 are detachable. After long-term use, the cutting blades 22 can be quickly disassembled for cleaning, minimizing cleaning time and increasing efficiency. This reduces equipment downtime, improves production efficiency, and lowers labor and time costs.

[0027] The cutting device in this embodiment has a simple structure, achieves uniform material shredding, and the shredded material particles are basically the same size. At the same time, the cutting blade 22 is easy to clean, reduces equipment downtime, and improves equipment production efficiency.

[0028] In one possible implementation, the cutter holder 21 includes two vertical plates 211 and a plurality of horizontal plates 212 evenly arranged between the two vertical plates 211. Preferably, the length of the two outermost horizontal plates 212 is greater than the length of the middle horizontal plate 212. At least one and at most two cutting blades 22 are detachably mounted on each horizontal plate 212. The cutting blades 22 have notches to facilitate fixing them to the respective horizontal plates 212. The cutting blades 22 extend along the width direction of the cutter holder 21. The cutting mechanism 2 can chop different materials. Generally, to accommodate uniform chopping of different materials, the position of the cutting blades 22 on the cutter holder 21 can be adjusted. Once the cutting blades 22 are adjusted to a suitable position and fixed on the cutter holder 21, they chop the material. The cutting blades 22 can be detached from the cutter holder 21 for easy cleaning. Preferably, two cutting blades 22 are provided on the two outermost horizontal plates 212, and one cutting blade 22 is provided on the remaining horizontal plates 212.

[0029] In one possible implementation, each of the horizontal plates 212 is evenly provided with multiple screw holes, and a screw 25 is inserted through the screw holes in the same row of the horizontal plates 212. The screw 25 is kept stable on the horizontal plates 212. Each cutting blade 22 is evenly provided with multiple strip grooves, and portions of the screws 25 are respectively engaged in the strip grooves on the cutting blade 22. The cutting blade 22 is locked to the horizontal plate 212 by multiple locking nuts 26 and the screws 25. Preferably, a washer is provided between the locking nut 26 and the cutting blade 22 to ensure that the locking nut is locked to the screw 25. Through the cooperation of the strip grooves, locking nuts 26 and screws 25, the cutting blade 22 can be fixed at different positions of the cutting blade holder 21 to meet the need for uniform chopping of different materials. When the cutting blade 22 needs to be cleaned, the locking nuts 26 are loosened, at which time the screws 25 are separated from the strip grooves, and the cutting blade 22 is removed from the cutting blade holder 21.

[0030] In one possible implementation, the frame 1 is provided with two guide sections, each guide section including two tracks 11 disposed opposite to each other on the frame 1. The tracks 11 are L-shaped and locked to the frame 1. Each vertical plate 211 is provided with a blade holder shaft 23, and a slider 24 is fixedly mounted on the blade holder shaft 23. The slider 24 is engaged between the two tracks 11 of the guide section and moves along the height direction of the tracks 11. The slider 24 moves up and down between the two tracks 11 of the guide section, thereby driving the cutter holder 21 and multiple cutter blades 22 to move up and down.

[0031] As one possible implementation, each of the connecting rods 32 has an upper bearing seat 321 and a lower bearing seat 322 threaded at both ends. The upper bearing seat 321 and the lower bearing seat 322 are suspended bearing seats. The end of the tool holder shaft 23 is fixedly connected to the upper bearing in the upper bearing seat 321. The upper bearing seat 321 is located outside the slider 24. Both ends of the drive shaft 31 are fixedly provided with eccentric sleeves 33. The structure and operation of the eccentric sleeves 33 are existing technologies and will not be described in detail here. The end of the drive shaft 31 is fixedly connected to the lower bearing in the lower bearing seat 322 through the eccentric sleeves 33. The rotation of the drive shaft 31 drives the rotation of the eccentric sleeve 33 (the eccentric sleeve 33 performs eccentric motion). Because of the presence of the eccentric sleeve 33, the center point of the lower bearing seat 322 is different from the center point of the eccentric sleeve 33, and there is an offset. Therefore, the lower bearing seat 322 actually drives the connecting rod 32, the upper bearing seat 321 and the tool holder shaft 23 to move up and down. Because the track 11 guides the slider 24 on the tool holder shaft 23, the cutting tool holder 21 and the cutting blade 22 eventually move up and down.

[0032] In one possible implementation, the upper bearing seat 321 has a first connecting groove on its base. The upper part of the connecting rod 32 passes through the first connecting groove and is threadedly connected thereto. The upper part of the connecting rod 32 is threadedly connected to a positive nut 34, which contacts or separates from the base of the upper bearing seat 321. The lower bearing seat 322 has a transition rod 35 threadedly connected thereto. The transition rod 35 has a transition connecting groove on its base. The lower part of the connecting rod 32 passes through the transition connecting groove and is threadedly connected thereto. The lower part of the connecting rod 32 is threadedly connected to a negative nut 36, which contacts or separates from the transition rod 35. Loosen the positive nut 34 and the negative nut 36, and manually rotate the connecting rod 32. After rotating, the connecting rod 32 moves up and down or down relative to the upper bearing seat 321 and the lower bearing seat 322, that is, the height of the connecting rod 32 changes. Then, tighten the positive nut 34 and the negative nut 36, and the connecting rod 32, the upper bearing seat 321, and the lower bearing seat 322 are fixed together again. Because the lower bearing seat 322 is fixed on the drive shaft 31, the rotation of the connecting rod 32, after moving up and down or down, drives the upper bearing seat 321 and the cutting mechanism 2 to move up and down or down, ultimately adjusting the distance between the cutting mechanism 2 and the conveyor belt 4 (adjusting the height of the cutting mechanism 2), thereby meeting the chopping requirements of different materials. It should be noted that the range of vertical movement of the connecting rod 32 is limited, allowing for fine adjustment of the height of the cutting mechanism 2.

[0033] In one possible implementation, each connecting rod 32 has a positive thread (not shown) and a negative thread (not shown) on its upper and lower parts, respectively. The positive and negative threads have opposite thread directions. The inner wall of the first connecting groove has a first internal thread (not shown) that matches the positive thread, and the inner wall of the transition connecting groove has a transition internal thread (not shown) that matches the negative thread. The upper part of the connecting rod 32 is fixedly connected to the seat of the upper bearing seat 321 through the positive thread and the first internal thread; the lower part of the connecting rod 32 is fixedly connected to the transition rod 35 through the negative thread and the transition internal thread.

[0034] In one possible implementation, the lower bearing seat 322 has a second connecting groove on its base, and a second internal thread (not shown in the figure) is provided on the inner wall of the second connecting groove. The outer wall of the transition rod 35 has an external thread (not shown in the figure) that matches the second internal thread. The lower part of the transition rod 35 passes through the second connecting groove and is threadedly connected to it. The base of the lower bearing seat 322 and the transition rod 35 are fixedly connected through the external thread and the second internal thread.

[0035] In one possible implementation, two support bearing seats 12 are arranged opposite each other on the frame 1. The support bearing seats 12 are locked onto the frame 1 and are vertical bearing seats with mounting bases. The two ends of the drive shaft 31 pass through the support bearings in the two support bearing seats 12 and are fixedly connected to them. The two eccentric sleeves 33 are located on the outside of the two support bearing seats 12. When the drive shaft 31 rotates, the drive shaft 31 and the support bearings in the support bearing seats 12 rotate relative to the two support bearing seats 12.

[0036] In one possible implementation, the drive mechanism 3 further includes a drive motor 37 locked and fixedly mounted on the frame 1. The output shaft of the drive motor 37 is fixedly connected to the drive pulley 38 and can drive it to rotate. A driven pulley 39 is fixedly mounted in the middle of the drive shaft 31, and a belt 5 is sleeved between the drive pulley 38 and the driven pulley 39. When the drive motor 37 starts, it drives the drive pulley 38 to rotate, which in turn drives the driven pulley 39 and the belt 5 to rotate, thus rotating the drive shaft 31.

[0037] In one possible implementation, a drive roller 7 and a driven roller 8 are rotatably mounted on the frame 1, and the conveyor belt 4 is wound between the drive roller 7 and the driven roller 8. The two ends of the drive roller 7 and the driven roller 8 are fixedly connected to a rotating bearing in a rotating bearing seat mounted on the frame 1, allowing the drive roller 7 and the driven roller 8 to rotate. A first motor 6 is locked and fixedly mounted on the frame 1. The output shaft of the first motor 6 is fixedly connected to and can drive a drive sprocket to rotate. A driven sprocket is fixedly mounted at the end of the drive roller 7, and a chain 9 is sleeved between the drive sprocket and the driven sprocket. When the first motor 6 is started, it drives the drive sprocket to rotate, which in turn drives the driven sprocket and the chain 9 to rotate, thus rotating the drive roller 7, which in turn drives the driven roller 8 and the conveyor belt 4 to rotate. Preferably, a chain cover is fixedly mounted on the frame 1, covering the chain 9 for protection.

[0038] The working process of the cutting device: The drive motor 37 starts, driving the drive pulley 38 to rotate, which in turn drives the driven pulley 39 and belt 5 to rotate, thus rotating the drive shaft 31. After the drive shaft 31 rotates, it drives the eccentric sleeve 33 to rotate. Because the center point of the lower bearing seat 322 and the center point of the eccentric sleeve 33 are different and there is an offset, the lower bearing seat 322 actually drives the connecting rod 32, the upper bearing seat 321 and the cutter holder shaft 23 to move up and down. Because the track 11 guides the slider 24 on the cutter holder shaft 23, the cutter holder 21 and the cutter blades 22 ultimately move up and down. When the conveyor belt 4 carries the material to below the multiple cutter blades 22, the multiple cutter blades 22 cut the material in sequence, and finally the material is cut evenly and quickly, and the size of the chopped material particles is basically the same.

[0039] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of this utility model should be included within the scope of the patent application of this utility model.
