[0002] A twin-shaft shredder is a type of crushing machine used for fine shredding. It is generally used to process unprocessed raw materials or scraps to make them smaller. Shredders are used in the plastic recycling industry and are often used to crush waste large-diameter PE plastic pipes, bundled plastic films, stacks of plastic sheets and head stock.

[0003] Existing patent CN218111369U discloses a novel dual-shaft shredding mechanism, belonging to the technical field of plastic pipe crushing equipment. It includes a housing and a drive motor. Inside the housing, a first roller and a second roller are mounted side-by-side and rotate. Shredding blades are evenly fitted onto the first and second rollers.

The pulleys are connected by a belt drive. A support frame is fixedly installed at the lower end of the housing. An air pump and a refrigeration box are installed to allow cold air to enter the interior of the blind hole and be blown out through the through-hole on the collar. This allows the cold air to cool the shredding blades, the first roller, and the second roller, preventing the shredding blades from overheating during prolonged use, which would reduce the shredding effect and prevent plastic pipes from sticking to the shredding blades.

[0004] Based on the search of the aforementioned patents and in conjunction with existing dual-shaft shredders, it was found that although the aforementioned dual-shaft shredder can cool the shredding blades and crush materials during use, the debris generated during material crushing is prone to overflow, polluting the air and even being inhaled by workers, affecting their health, thus resulting in poor practicality. Utility Model Content

[0005] The purpose of this invention is to provide a transmission device for a twin-shaft shredder, in order to solve the problem mentioned in the background art that, although existing twin-shaft shredders can cool the shredding blades and crush materials, the debris generated during material crushing is prone to overflow, polluting the air and even being inhaled by workers, thus affecting their health and resulting in poor practicality.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting up the machine body and spraying components, the water pump can draw water out through the suction pipe and spray it out through the nozzle. This can treat debris and dust, prevent them from overflowing and polluting the air, protect workers, and cool down the shredding roller to prevent it from overheating and sticking plastic. The filter screen can filter the water on the surface of the crushed material, which facilitates the recycling of water resources and greatly improves the practicality of the device.

[0015] 2. By incorporating an extrusion component, the first motor controls the screw to rotate, which in turn drives the moving frame and pressure plate to move downwards.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 This utility model provides a technical solution: a transmission device for a dual-shaft shredder, comprising a body 1, a spraying component for preventing debris and dust from overflowing, and a squeezing component for improving shredding efficiency. The spraying component includes a water tank 21 fixedly connected to the bottom of the body 1, support plates 22 fixedly connected to both sides of the water tank 21, a water pump 23 fixedly connected to the top of the support plates 22, a suction pipe 24 fixedly connected to one side of the water pump 23, a discharge pipe 25 fixedly connected to the other side of the water pump 23, and a suction pipe 24 fixedly connected to one side of the discharge pipe 25. The system includes multiple fixedly connected nozzles 26, a filter screen 27 fixedly connected to the inner wall of the water tank 21, and a material pushing component for discharging materials. A suction pipe 24 is connected to the water tank 21, and a water outlet pipe 25 penetrates the machine body 1 and extends into the machine body 1. When the water pump 23 is activated, it can draw water from the water tank 21 through the suction pipe 24 and spray water through the water outlet pipe 25 and nozzles 26. This system can suppress dust and impurities, preventing them from overflowing and polluting the environment, while also preventing workers from inhaling them. Furthermore, the sprayed water can also be used to clean shredded materials. Roller 73 is cooled to prevent plastics and other materials from sticking to it. Filter screen 27 filters the material, and the filtered water can be recycled, saving resources. The pushing component includes a discharge port 41 located on one side of the water tank 21, a fixed frame 42 fixedly connected to the other side of the water tank 21, a cylinder 43 fixedly connected to one side of the fixed frame 42, and a pushing plate 44 fixedly connected to the output end of the cylinder 43. The bottom of the pushing plate 44 contacts the top of the filter screen 27. Activation of the cylinder 43 pushes the pushing plate 44. 4. The movement of the pusher plate 44 allows the crushed material at the top of the filter screen 27 to be discharged through the outlet 41, preventing material from accumulating on the filter screen 27 and affecting its efficiency. A baffle 61 is inserted into the outlet 41, and a handle 62 is fixedly connected to one side of the baffle 61. The baffle 61 can be easily moved by the handle 62, and can be removed from the outlet 41 to facilitate the discharge of the crushed material. At the same time, when the baffle 61 is inserted into the outlet 41, it can block the material.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 The extrusion component includes a bracket 31 fixedly connected to the side of the machine body 1, a first motor 32 fixedly connected to the top side of the bracket 31, a lead screw 33 fixedly connected to the bottom of the first motor 32, a movable frame 34 connected to the outside of the lead screw 33, and a pressure plate 35 fixedly connected to the bottom of the movable frame 34. The lead screw 33 is rotatably connected to the bracket 31 and screwed to the movable frame 34. The first motor 32 can control the rotation of the lead screw 33, which causes the movable frame 34 to move vertically, thereby controlling the vertical movement of the pressure plate 35. This allows the pressure plate 35 to push the material into close contact with the shredding roller 73, making it easier to crush materials with rounded edges or smooth surfaces. A fixing rod 51 is fixedly connected to the top side of the bracket 31 away from the lead screw 33. A through-hole 52 is opened on the top side of the movable frame 34, and the fixing rod 51 is slidably connected to the through-hole 52. The fixing rod 51 can slide within the through-hole 52 to prevent the movable frame 34 from colliding with the lead screw 33. Synchronous rotation ensures stable vertical movement of the moving frame 34. A first rotating shaft 71 is rotatably connected to one side of the machine body 1, and a second rotating shaft 72 is rotatably connected to the other side of the machine body 1. Shredding rollers 73 are fixedly connected to the outer sides of both the first rotating shaft 71 and the second rotating shaft 72. A main gear 74 is fixedly connected to the outer side of the first rotating shaft 71, and a driven gear 75 is fixedly connected to the outer side of the second rotating shaft 72. A second motor 76 is fixedly connected to one end of the first rotating shaft 71. The main gear 74 and the driven gear 75 mesh, and the second motor 76 can control the rotation of the first rotating shaft 71 and the main gear 74. The main gear 74 can drive the driven gear 75 and the second rotating shaft 72 to reverse, thereby causing the two shredding rollers 73 to rotate in opposite directions, which can shred the material and reduce the cost of use. A mounting frame 761 is fixedly connected to one side of the second motor 76. The mounting frame 761 is fixedly connected to the machine body 1 and can support and fix the second motor 76, improving the working stability of the second motor 76.

[0025] Working principle: During operation, the second motor 76 is started, which drives the first rotating shaft 71 and the main gear 74 to rotate. The main gear 74 drives the driven gear 75 and the second rotating shaft 72 to rotate in reverse. The first rotating shaft 71 and the second rotating shaft 72 drive the shredding roller 73 to rotate in the opposite direction. Material can then be fed between the two shredding rollers 73. The rotation of the shredding rollers 73 shreds the material. The water pump 23 starts and draws water from the water tank 21 through the suction pipe 24, and then sprays it out through the water outlet pipe 25 and the nozzle 26. This can suppress dust generated during shredding and prevent dust from overflowing. At the same time, the water, carrying the shredded material, falls onto the top of the filter screen 27. The filter screen 27 filters the material, facilitating the recycling of water resources. The first motor 32, when started, drives the lead screw 33 to rotate. The rotation of the lead screw 33 drives the moving frame 34 to move downward. The moving frame 34, in turn, drives the pressing plate 35 to move downward. The pressing plate 35, when moving downward, presses the material down, making it come into close contact with the shredding roller 73. This makes it easier to crush materials with rounded edges or smooth surfaces. After crushing, the baffle 61 can be removed by the handle 62. The cylinder 43 is then started, which pushes the pusher plate 44 to move. The pusher plate 44 discharges the material through the discharge port 41. After discharge, the baffle 61 can be reinserted into the discharge port 41. This is the entire working process of the device. Any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
