Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and in particular to a waste crushing device. Background Technology

[0002] Injection molding is a method of shaping industrial products. Due to its high efficiency and precision, injection molding is widely used in various fields, such as injection-molded parts for automotive oil cans, printers, medical devices, and battery covers. Injection molding is typically achieved using an injection molding machine, which is the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding is achieved through the injection molding machine and the mold. After injection molding, the molded product and injection waste are formed inside the mold. The injection waste can be crushed and reused.

[0003] Currently, existing crushing devices are usually equipped with feed pipes for injection molding waste to enter the crushing device. However, due to the different shapes and irregular structures of injection molding waste, it is easy for the waste to intertwine during the feeding process. This causes the waste to come into contact with the inner wall of the square tube and cannot continue to descend, resulting in blockage of the feed pipe and seriously affecting the normal feeding efficiency of the crushing device. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a waste crushing device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waste crushing device, including a crushing tank, a crushing component is provided inside the crushing tank, a feed inlet is provided at the top of the crushing tank and a discharge outlet is provided at the bottom, a square tube is provided at the discharge outlet at the top of the crushing tank, two fixed grooves are vertically spaced on both opposite sides of the square tube, a rotating roller is rotatably provided in the fixed groove, the two rotating rollers are connected by a conveyor belt, a driving component is provided at the top of the crushing tank to drive the two lower rotating rollers to rotate synchronously in opposite directions, sliding holes are provided on the other opposite sides of the square tube, a pushing component is provided on the square tube corresponding to the sliding hole, the pushing component includes a sliding platform slidably provided in the sliding hole, a mounting frame is provided on the outer wall of the square tube, a driving cylinder is horizontally provided on the mounting frame, and the piston rod of the driving cylinder is connected to the sliding platform.

[0006] By adopting the above technical solution, a crushing tank, a square tube, rotating rollers, a drive assembly, and a pushing assembly are set up. After the injection molding waste enters the square tube, two sliding tables are driven by two drive cylinders to slide back and forth, squeezing the injection molding waste inside the square tube. This prevents the injection molding waste from contacting the inner wall of the square tube and thus preventing it from continuing to descend and causing blockage. At the same time, the drive assembly drives the two lower rotating rollers to rotate synchronously in opposite directions, driving the two conveyor belts to rotate. The injection molding waste in contact with the conveyor belts receives downward force, allowing the injection molding waste to be conveyed downward, further preventing blockage and ensuring high feeding efficiency.

[0007] Furthermore, the mounting bracket includes two connecting rods vertically spaced on the square tube, the two connecting rods being located on the upper and lower sides of the sliding table respectively, and a mounting plate being provided at the ends of the two connecting rods away from the square tube. The driving cylinder is mounted on the mounting plate, and the piston rod of the driving cylinder passes through the mounting plate and is connected to the sliding table.

[0008] Furthermore, connecting blocks are provided on both the upper and lower sides of the sliding platform, and guide holes are horizontally opened on the connecting blocks, with the guide holes slidably connected to the corresponding connecting rods.

[0009] By adopting the above technical solution, a connecting block and a guide hole are set up. When the sliding table slides, it drives the connecting block to move. The connecting rod restricts the sliding of the connecting block, thereby ensuring the stability of the sliding table.

[0010] Furthermore, the two sliding platforms are provided with mounting grooves on opposite sides, and the openings of the two mounting grooves are opposite. A fixing rod is provided in the mounting groove, and a sliding tube is slidably sleeved on the fixing rod. A compression spring is sleeved on the rod body of the fixing rod located between the sliding tube and the bottom of the mounting groove. A connecting plate is provided at the end of the sliding tube away from the bottom of the mounting groove, and the piston rod of the driving cylinder passes through the mounting plate and is connected to the connecting plate.

[0011] By adopting the above technical solution, and setting up an installation groove, a fixed rod, a sliding tube, and a compression spring, when there is a lot of injection waste in the square tube and the sliding table experiences greater resistance, the fixed rod slides inside the sliding tube, and the compression spring is compressed, thus preventing damage to the drive cylinder.

[0012] Furthermore, the drive assembly includes a drive motor horizontally mounted on the top of the crushing tank. A drive synchronous pulley is mounted on the output shaft of the drive motor. Trunnions are mounted at both ends of the lower rotating roller. A driven synchronous pulley and a first sprocket are respectively fixedly fitted onto the two trunnions on one of the lower rotating rollers. The driven synchronous pulley and the drive synchronous pulley are connected by a connecting synchronous belt. A rotating shaft is horizontally rotatably mounted on one side of the square tube. A second sprocket and a drive wheel are fixedly fitted onto the rotating shaft. The second sprocket and the first sprocket are connected by a chain. A driven wheel is fixedly fitted onto one of the trunnions on the other lower rotating roller, and the driven wheel meshes with the drive wheel.

[0013] By adopting the above technical solution, a drive motor, a synchronous pulley, a trunnion, a first sprocket, a second sprocket, a driven wheel, and another driven wheel are set up. The drive motor drives the active synchronous pulley to rotate, which in turn drives the driven synchronous pulley, the trunnion, the rotating roller, and the first sprocket to rotate, thereby driving the second sprocket, the rotating shaft, and the drive wheel to rotate, which in turn drives the driven wheel and another rotating shaft to rotate.

[0014] Furthermore, the pulverizing assembly includes a rotating shaft that is vertically rotatably disposed inside the pulverizing tank. Several blades are disposed on the rotating shaft. The upper end of the rotating shaft passes through the top of the pulverizing tank and is provided with a driven bevel gear. An active bevel gear is fixedly sleeved on the output shaft of the drive motor. The active bevel gear meshes with the driven bevel gear.

[0015] By adopting the above technical solution, a rotating shaft, blades, driven bevel gears, and driving bevel gears are set up. When the output shaft of the drive motor rotates, it drives the driving bevel gear to rotate, thereby driving the driven bevel gears and the rotating shaft to rotate, so that the blades rotate to crush the injection molding waste.

[0016] Furthermore, the square tube is provided with several receiving grooves spaced apart on its body between two vertically spaced rotating rollers, and several support rollers are horizontally rotatably arranged in the receiving grooves.

[0017] In summary, this utility model has the following beneficial effects: In this application, a crushing tank, a square tube, rotating rollers, a drive assembly, and a pushing assembly are provided. After the injection molding waste enters the square tube, two sliding tables are driven by two drive cylinders to slide back and forth, compressing the injection molding waste inside the square tube and preventing it from contacting the inner wall of the square tube and thus preventing further descent and blockage. Simultaneously, the drive assembly drives the two lower rotating rollers to rotate synchronously in opposite directions, driving the two conveyor belts to rotate. The injection molding waste in contact with the conveyor belts receives downward force, allowing the injection molding waste to be conveyed downwards, further preventing blockage and ensuring high feeding efficiency.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-7As shown in the figure, this application discloses a waste crushing device, including a crushing tank 10, a crushing component 20, a square tube 11, a driving component 30, and a pushing component 40. The crushing component 20 is disposed inside the crushing tank 10. The crushing tank 10 has a feed inlet at the top and a discharge outlet at the bottom. The square tube 11 is disposed at the top of the crushing tank 10 at the discharge outlet. Two fixed grooves 12 are vertically spaced on both sides of the square tube 11. Rotating rollers 13 are rotatably disposed in the fixed grooves 12. Two vertically adjacent rotating rollers 13 are connected by a conveyor belt 14. The driving component 30 is disposed at the top of the crushing tank 10 and is used to drive the two lower rotating rollers 13 to rotate synchronously in opposite directions. Sliding holes 15 are provided on the opposite sides of the square tube 11. Two pushing components 40 are provided on the square tube 11, each corresponding to one of the two sliding holes 15. Each pushing component 40 includes a sliding table 41, a mounting frame 42, and a driving cylinder 43. The sliding table 41 is slidably disposed within the sliding hole 15, the mounting frame 42 is disposed on the outer wall of the square tube 11, and the driving cylinder 43 is horizontally disposed on the mounting frame 42. The piston rod of the driving cylinder 43 is connected to the sliding table 41. After the injection molding waste enters the square tube 11, the two sliding tables 41 are driven by the two driving cylinders 43 to slide back and forth, squeezing the injection molding waste inside the square tube 11 and preventing it from colliding with the inner wall of the square tube 11 and thus preventing it from continuing to descend and causing blockage. At the same time, the driving component 30 drives the two lower rotating rollers 13 to rotate synchronously in opposite directions, driving the two conveyor belts 14 to rotate. The injection molding waste in contact with the conveyor belts 14 receives downward force, allowing the injection molding waste to be conveyed downward, further preventing blockage and ensuring high feeding efficiency. The square tube 11 is located between two vertically spaced rotating rollers 13 and has several receiving grooves 16 spaced apart on its tube body. Several support rollers 17 are horizontally rotatably arranged in the receiving grooves 16 to ensure the stability of the conveyor belt 14.

[0028] Specifically, the drive assembly 30 includes a drive motor 31 horizontally mounted on the top of the crushing tank 10. A drive synchronous pulley 32 is mounted on the output shaft of the drive motor 31. Trunnions are mounted at both ends of the lower rotating roller 13. A driven synchronous pulley 33 and a first sprocket 34 are respectively fixedly mounted on the two trunnions of one of the lower rotating rollers 13. The driven synchronous pulley 33 and the drive synchronous pulley 32 are connected by a connecting synchronous belt 35. The drive motor 31 rotates the drive synchronous pulley 32, causing the driven synchronous pulley 33, trunnions, rotating roller 13, and first sprocket 34 to rotate. A rotating shaft 36 is horizontally rotatably mounted on one side of the square tube 11. A second sprocket 37 and a drive wheel 38 are fixedly mounted on the rotating shaft 36. The second sprocket 37 and the first sprocket 34 are connected by a chain 371. The rotation of the first sprocket 34 causes the second sprocket 37, rotating shaft 36, and drive wheel 38 to rotate. A driven wheel 39 is fixedly sleeved on one of the trunnions of the other lower rotating roller 13. The driven wheel 39 meshes with the driving wheel 38. The rotation of the driving wheel 38 drives the driven wheel 39 and the rotating roller 13 connected to the driven wheel 39 to rotate.

[0029] In the configuration, the crushing assembly 20 includes a rotating shaft 21 vertically rotatably disposed within the crushing tank 10. Several blades 22 are disposed on the rotating shaft 21. The upper end of the rotating shaft 21 passes through the top of the crushing tank 10 and is provided with a driven bevel gear 23. An active bevel gear 24 is fixedly sleeved on the output shaft of the drive motor 31. The active bevel gear 24 meshes with the driven bevel gear 23. When the output shaft of the drive motor 31 rotates, it drives the active bevel gear 24 to rotate, thereby driving the driven bevel gear 23 and the rotating shaft 21 to rotate, causing the blades 22 to rotate and crush the injection molding waste.

[0030] In its specific configuration, the mounting bracket 42 includes connecting rods 421 and mounting plates 422. There are two connecting rods 421, vertically spaced apart on the square tube 11. The two connecting rods 421 are located on the upper and lower sides of the sliding table 41, respectively. The ends of the two connecting rods 421 furthest from the square tube 11 share a common mounting plate 422. A drive cylinder 43 is mounted on the mounting plate 422, and its piston rod passes through the mounting plate 422 and connects to the sliding table 41. Connecting blocks 416 are provided on both the upper and lower sides of the sliding table 41. Each connecting block 416 has a horizontally opening guide hole, which slidably connects to the corresponding connecting rod 421. When the sliding table 41 slides, it moves the connecting blocks 416. The connecting rods 421 restrict the sliding of the connecting blocks 416, thereby ensuring the stability of the sliding table 41.

[0031] Two sliding platforms 41 are provided with mounting grooves 411 on opposite sides of each other. The openings of the two mounting grooves 411 are opposite. A fixing rod 412 is provided in the mounting groove 411. A sliding tube 413 is slidably sleeved on the fixing rod 412. A compression spring 414 is sleeved on the rod of the fixing rod 412 located between the sliding tube 413 and the bottom of the mounting groove 411. One end of the compression spring 414 is connected to the sliding tube 413 and the other end is connected to the bottom of the mounting groove 411. A connecting plate 415 is provided at the end of the sliding tube 413 away from the bottom of the mounting groove 411. The piston rod of the drive cylinder 43 passes through the mounting plate 422 and connects to the connecting plate 415. When there is a lot of injection waste in the square tube 11 and the sliding platform 41 experiences greater resistance, the fixing rod 412 slides in the sliding tube 413, and the compression spring 414 is compressed to prevent damage to the drive cylinder 43.

[0032] The operating principle of the waste crushing device in this embodiment is as follows:

[0033] After the injection molding waste enters the square tube 11, the drive cylinder 43 is activated to drive the connecting plate 415, sliding tube 413, fixed rod 412, and sliding table 41 to move. The two sliding tables 41 slide back and forth, squeezing the injection molding waste in the square tube 11.

[0034] Simultaneously, the drive motor 31 is activated to drive the active synchronous pulley 32 and the active bevel gear 24 to rotate. The rotation of the active synchronous pulley 32 drives the driven synchronous pulley 33, trunnion, rotating roller 13, and first sprocket 34 to rotate, thereby driving the second sprocket 37, rotating shaft 36, and drive wheel 38 to rotate, which in turn drives the driven wheel 39 and another rotating shaft 36 to rotate, causing the two conveyor belts 14 to rotate synchronously in opposite directions, so that the injection molding waste is conveyed downwards, further preventing blockage. When the drive bevel gear 24 rotates, it drives the driven bevel gear 23 and rotating shaft 21 to rotate, causing the blade 22 to rotate and crush the injection molding waste. The crushed injection molding waste is discharged from the outlet.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
