[0035] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0036] Please refer to Figure 1-5 The technical solution of this utility model is: a material crushing and recycling device, comprising: a frame 1;

[0037] The power unit 2 is mounted on the frame 1 and located in the middle area of ​​the frame 1. The power unit 2 includes two drive shafts 3 extending to both ends of the frame 1.

[0038] The crushing unit 4 includes two units located at both ends of the frame 1, including a transmission roller assembly and a feed inlet 401 and a crushing tooth assembly 43 located on both sides of the transmission roller 44 assembly along the transmission direction of the transmission roller 44 assembly. The crushing tooth assembly 43 and the transmission roller 44 assembly are both connected to the transmission shaft 3.

[0039] For details, please refer to Figures 1-3 The specific structure of the edge material crushing and recycling device provided in this application is as follows: It includes a frame 1, which is mounted on the ground. A power unit 2 is located in the middle area of ​​the upper surface of the frame 1. The power unit 2 includes a drive motor and a gearbox. Two drive shafts 3 extend from the gearbox. The gearbox uses a hypoid reducer. The crushing unit 4 and the conveyor shaft are connected by a coupling 31, thereby driving two crushing units 4 through a single power source. (Refer to...) Figures 3-6The crushing unit 4 includes a feed inlet 401. Below the feed inlet 401, a set of conveyor rollers 44 is arranged. The conveyor rollers 44 are located below the feed inlet 401 and on both sides of it, and are connected to the drive shaft 3. Below the conveyor rollers 44, a crushing tooth assembly 43 is arranged. This arrangement allows for the placement of the edge material crushing and recycling device provided in this application next to the edge material cutting device. The two crushing units 4 crush the two cut edge materials. Specifically, the edge material is inserted into the feed inlet 401, conveyed by the conveyor rollers 44, and then crushed by the crushing tooth assembly 43. This avoids the edge material recycling process and improves crushing efficiency. The specific structures of the conveyor rollers 44 and the crushing tooth assembly 43 are described below.

[0040] Furthermore, as a preferred embodiment, refer to Figures 1-4 , Figures 13-15 A recovery hopper 5 is provided below the crushing unit 4. Specifically, it is set on the frame 1 and located below the crushing unit 4. The recovery hopper 5 is set along the interval direction between the two crushing units 4. A auger 53 is set inside. One end of the recovery hopper 5 is provided with a discharge port. The end of the auger 53 away from the discharge port is connected to the drive shaft 3.

[0041] Specifically, the hopper is designed with an open top and is located below the recycling unit. One end of the hopper is closed, and the other end has an outlet with a guide section 50. An extension section 51 extends upward from the side of the hopper toward the crushing unit 4. The extension section 51 guides the crushed material to ensure that it enters the recycling hopper 5. A auger 53 is installed inside the recycling hopper 5. The auger 53 is connected to the drive shaft 3. The rotation of the auger 53 conveys the crushed material out through the guide section 50, which is conducive to the recycling of waste.

[0042] Furthermore, as a specific implementation method, the specific structure of the crushing unit 4 is as follows: (Refer to...) Figures 3-10 The crushing unit 4 includes two support plates 46 spaced apart, and the conveying roller 44 assembly includes two conveying rollers 44 spaced apart, with the two conveying rollers 44 floating along directions that are closer to each other and further apart.

[0043] Specifically, two support plates 46 are arranged parallel to each other on the frame 1. The support plates 46 are rectangular plates with connecting holes 461 at each of the four corners. The two support plates 46 can be connected through the connecting holes 461. In one specific implementation, a screw can be passed through the two connecting holes 461 in sequence, and a support sleeve can be fitted on the screw between the two connecting plates. The support sleeve supports and positions the two connecting plates. Nuts are installed at the ends of the screws that extend out of the two connecting plates to achieve the effect of connecting and fixing the support plates 46.

[0044] Furthermore, one conveyor roller 44 is rotatably mounted on the support plate 46 and is connected to the drive shaft 3. The support plate 46 is provided with a strip hole 460. The roller shaft 441 of the other conveyor roller 44 is guided and engaged with the strip hole 460. Elastic elements are provided between the two ends of the roller shaft 441 and the two support plates 46. The elastic elements provide elastic force to the roller shaft 441 to bring the two conveyor rollers 44 closer to each other.

[0045] Furthermore, the side wall of the support plate 46 is provided with a through hole 462 communicating with the strip hole 460, and the elastic element is a compression spring disposed in the through hole 462.

[0046] For details, please refer to Figures 4-8 The conveyor roller group 44 includes two conveyor rollers 44. One conveyor roller 44 has its two ends rotatably connected to two support plates 46. The other conveyor roller shaft 441 has its two ends slidably engaged with the guide hole 460. Specifically, the conveyor roller 44 with its two ends rotatably engaged with the support plates 46 is called the first roller. The first roller and the shaft 441 are fixedly connected, meaning the shaft 441 can drive the first roller to rotate. The other conveyor roller 44 is called the second roller. The second roller is rotatably engaged with the shaft 441. Specifically, the second roller shaft 441 can be milled with two opposing and parallel mating surfaces. The distance between the two mating surfaces is adapted to the width of the guide hole 460, so that the second roller shaft 441 is guided and non-rotatably engaged with the guide hole 460. The above-mentioned engagement method is a common technique in the art, and its specific structure will not be described in detail here. Those skilled in the art should understand it. (Refer to...) Figure 8 One end of the through hole 462 is connected to one end of the strip hole 460. A compression spring can be installed inside. An internal thread is provided at the end of the through hole 462 away from the strip hole 460. A bolt is connected through the internal thread, and the bolt presses and limits the compression spring, so that the compression spring provides elastic force to the roller shaft 441 of the second roller. With this arrangement, when the edge material enters between the two conveying rollers 44, the second roller can squeeze the edge material into contact with the roller surface of the first roller. When the first roller rotates, it applies a conveying force to the edge material through friction. The floating setting of the second roller can adapt to edge materials of different thicknesses. The pressing force of the compression spring on the second roller can be adjusted by adjusting the tightening force of the bolt.

[0047] Furthermore, as a specific embodiment, the crushing gear assembly 43 includes a first shaft 41 and a second shaft 42 arranged in parallel intervals. Multiple crushing gears 431 are evenly spaced on both the first shaft 41 and the second shaft 42, and the crushing gears 431 on the first shaft 41 and the second shaft 42 are staggered. One end of the first shaft 41 is connected to the transmission shaft 3, and the other end is connected to the conveying roller 44 for transmission.

[0048] Specifically, two support plates 46 are spaced apart, and an outer shell 40 is provided on the outside. The outer shell 40 includes a cover plate 403 formed by bending and overlapping the two support plates 46, and two first side plates 404 provided on both sides of the two support plates 46. Each of the two first side plates 404 has a clearance opening 402 corresponding to the first shaft 41. The cover plate 403 includes two second side plates 4030 and a top plate. The feed inlet 401 is provided on the top plate. The top plate and the second side plates 4030 are both provided with second strip holes 4031. The second strip holes 403 on the top plate are arranged along the axial direction of the transmission shaft 3, and the second strip holes 4031 on the second side plates 4030 are arranged in the vertical direction. The support plates 46 are provided with threaded holes corresponding to the second strip holes 4031, so that screws can be threaded through the second strip holes 4031 to connect with the support plates 46 and fix the outer shell 40. Multiple crushing gears 431 are sleeved on the first shaft 41 and the second shaft 42. (Reference) Figure 5 , Figure 6 The crushing gears 431 on the first shaft 41 and the second shaft 42 are arranged at intervals. When the edge material passes through the crushing gear 431, the edge material is squeezed by the tooth tip 4311 of the crushing gear 431, so as to achieve the effect of cutting and crushing the edge material.

[0049] Furthermore, as a specific implementation, both the first shaft 41 and the second shaft 42 are provided with transmission gears 420 at one end near the transmission shaft 3, and the two transmission gears 420 mesh; the other end of the first shaft 41 is provided with a first wheel 410, and the end of a conveying roller 44 is provided with a second wheel 440, and the first wheel 410 and the second wheel 440 are connected in a driving connection. (Reference) Figure 5 , Figure 6 The first shaft 41 and the second shaft 42 are connected by a transmission gear 420, so that the first shaft 41 and the second shaft 42 can rotate in opposite directions. The other end of the first shaft 41 is provided with a first wheel 410, a second wheel 440 and a second wheel 440 on a conveyor roller 44, so as to drive the conveyor roller 44. The first wheel 410 and the second wheel 440 can both be sprockets, and the first wheel 410 and the second wheel 440 are driven by a chain.

[0050] Furthermore, as a specific implementation method, refer to Figure 4 , Figure 5 , Figure 14 The first shaft 41 has a first wheel 410 at one end that is connected to the auger 53 via a drive mechanism. Specifically, a sprocket can be installed at one end of the first shaft 41 that passes through the first wheel 410, and a sprocket is also installed at the connecting end 530 of the auger 53, connecting the first wheel 410 and the auger 53 via a chain drive. Specifically, two reinforcing ribs 52 are provided in the middle area of ​​the recycling hopper 5, which helps to improve the strength of the recycling hopper 5.

[0051] Furthermore, as a specific implementation, the specific structure of the crushing gear 431 is as follows: (Refer to...) Figure 10 , Figure 11 One side of the crushing gear 431 is coaxially provided with a step 4310. The axial dimension of the step 4310 is larger than the axial dimension of the crushing gear 431, and the difference between the two ranges from 0.015 mm to 0.025 mm.

[0052] Specifically, the crushing gear 431 is provided with a step 4310, the radius of which is 35mm. The radius of the root portion of the crushing gear 431 is 42mm. A mating hole 4312 is provided in the middle area, and a keyway 4313 is provided on the side wall of the mating hole 4312. A mating key is provided on the first shaft 41 and the second shaft 42, so that the first shaft 41 and the second shaft 42 can be driven and engaged with the crushing gear 431. By providing the step 4310, when multiple crushing gears 431 are successively fitted onto the first shaft 41 or the second shaft 42, the step 4310 forms an interval area. Thus, when the two crushing gear assemblies 43 are engaged, the tooth tip 4311 on the first shaft 41 can extend into the space between the two crushing gears 431 on the second shaft 42.

[0053] For details, please refer to Figure 12 The tooth tip 4311 includes a tooth top 43111, a front tooth surface 43112, a tooth shoulder 43110, and a rear tooth surface 43113. In a specific implementation, during operation, the rotation direction of the crushing gear 431 is from the rear tooth surface 43113 to the front tooth surface 43112. The specific parameters of the tooth tip 4311 are: the tooth top 43111 intersects the front tooth surface 43112, and the radius of the intersection point of the tooth top 43111 and the front tooth surface 43112 is perpendicular to the tooth top 43111. The included angle α between tooth 11 and front tooth surface 43112 is 96°, the included angle β between tooth shoulder 43110 and front tooth surface 43112 is 51°, the included angle θ between tooth shoulder 43110 and rear tooth surface 43113 is 24°, the size of tooth tip 43111 is 1 mm, the distance L1 from tooth tip 43111 to tooth root is 12.04, and the size of tooth shoulder 43110 from the connection position with tooth tip 43111 to the connection position with rear tooth surface 43113 is 5.25 mm.

[0054] Furthermore, as a specific implementation, each crushing gear assembly 43 is equipped with a cleaning component 45, which includes a plurality of comb teeth 451 corresponding one-to-one with the crushing gear 431. The comb teeth 451 are disposed in the gap between two adjacent crushing gears 431. Specifically, refer to... Figure 6 , Figure 7 It is also equipped with a cleaning component 45, which is located between two support plates 46 and includes multiple comb teeth 451. The comb teeth 451 extend into the gap between the crushing gears 431 to clean the material stuck in the gap.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
