Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiberglass processing technology, and more specifically, to a shredding mechanism for a shredder. Background Technology
[0002] Fiberglass, or fiber-reinforced plastic, generally refers to reinforced plastics made by reinforcing unsaturated polyester, epoxy resin, and phenolic resin matrices with glass fibers, using glass fibers or their products as reinforcing materials. It is different from tempered glass.
[0003] Existing fiberglass crushing devices only employ shearing or tearing methods, both of which have limitations and are difficult to achieve the desired crushing effect.
[0004] A search revealed that Chinese patent application number CN202322210258.1 discloses a fiberglass crushing device. By adding a transfer machine between the shredder and the shearer, intermediate products can be directly transferred into the shearer, thereby avoiding manual transfer, optimizing the operation process and improving production efficiency.
[0005] When the aforementioned fiberglass crushing device is in actual use, the fiberglass fiber fragments will be thrown out by the high-speed rotating blades during the tearing process, which may cause injury to the workers. At the same time, the fiber dust in the fiberglass will be dispersed into the external environment, thus polluting the air quality. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a shredding mechanism for a shredder to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A shredding mechanism for a shredder includes a shredder body, a protective box fixedly connected to the top of the shredder body, and protective components installed inside the protective box;
[0009] The protective assembly includes a support frame, which is fixedly connected to the upper surface of the protective box. A first motor is installed on the top of the support frame, and a threaded rod is installed on the output end of the first motor. A movable plate is threadedly connected to the outer side of the threaded rod. A support rod and a connecting rod are fixedly connected to the bottom of the movable plate. The support rod is installed between two connecting rods. A pressing plate is fixedly connected to the bottom end of both the support rod and the connecting rod. Two sliding grooves are opened on the inner side of the support frame.
[0010] By adopting the above technical solution: the movable plate can drive the support rod and connecting rod to move downwards, the two slides provide guidance for the movement of the movable plate, so that the movable plate can stably push the pressing plate downwards, and the two connecting rods can provide support for the pressing plate, so that the pressing plate can stably apply pressure to the fiberglass.
[0011] As a further description of the above technical solution: a filter screen is provided on one side of the protective box, a dust collection box is provided on one side of the filter screen, a dust collection pipe is connected to one end of the dust collection box, a suction fan is provided at one end of the suction pipe, a conveying pipe is connected to the output end of the suction fan, and a dust collection box is connected to one end of the conveying pipe.
[0012] By adopting the above technical solution: the filter screen can effectively prevent large waste fragments from being sucked into the dust collection box, and the fan can transport dust into the dust collection box through the suction pipe, which is convenient for absorbing the dust from the shredded fiberglass and transporting it into the dust collection box for centralized collection.
[0013] As a further description of the above technical solution: two shredding support frames are fixedly connected to the inside of the shredder body, and a shredding mechanism is installed inside the shredder body. The shredding mechanism includes a second motor. One side of the shredder body is fixedly connected to the second motor by screws. A first sprocket is installed at the output end of the second motor. A chain is provided on the outside of the first sprocket, and a second sprocket is provided on the inside of the chain. A rotating shaft is inserted into the inside of both the first sprocket and the second sprocket.
[0014] By adopting the above technical solution: the first sprocket can drive the second sprocket to rotate under the action of the chain, so that the two shafts can rotate at the same time. Both shafts drive the shredding blades to move in a cross motion through multiple shredding discs, which makes it easier to shred the fiberglass.
[0015] The technical effects and advantages of this utility model are:
[0016] 1. By setting up protective components, compared with existing technologies, the downward movement of the movable plate can drive the pressing plate downward, and the pressing plate can then squeeze the fiberglass to be shredded downward, thereby increasing the contact area between the fiberglass and the shredding blades. The pressing plate adhering to the fiberglass can effectively block the splashing of shredded waste, reducing the possibility of waste splashing, thereby protecting the surrounding working environment and the safety of workers.
[0017] 2. By setting up a shredding structure, compared with the existing technology, the rotation of two second sprockets can drive multiple shredding blades to move in a cross motion, thereby powerfully shredding the waste material. At the same time, it can ensure that the fiberglass waste obtains uniform particle size during the crushing process, thus improving the shredding efficiency. Attached Figure Description

The support rod 7 is installed between the two connecting rods 8. A pressing plate 9 is fixedly connected to the bottom of both the support rod 7 and the connecting rod 8. Two sliding grooves 10 are opened on the inner side of the support frame 3. The support frame 3 drives the first motor 4 to rotate, so that the first motor 4 can drive the threaded rod 5 to rotate. The threaded rod 5 can drive the movable plate 6 to slide inside the sliding groove 10 through the thread, so that the movable plate 6 can push the support rod 7 and the connecting rod 8 to move downward. The support rod 7 and the connecting rod 8 can push the pressing plate 9 downward to apply pressure to the fiberglass being shredded, thereby increasing the contact area between the fiberglass and the shredding blade 23. At the same time, the pressing plate 9 can adhere to the upper surface of the fiberglass, which can effectively block the fiberglass fragments from flying, thereby reducing the impact of waste flying on the surrounding environment.
[0028] Reference Figure 2 As shown, a filter screen 11 is provided on one side of the protective box 2, and a dust collection box 12 is provided on the other side of the filter screen 11. One end of the dust collection box 12 is connected to a suction pipe 13, and one end of the suction pipe 13 is provided with a suction fan 14. The output end of the suction fan 14 is connected to a conveying pipe 15, and one end of the conveying pipe 15 is connected to a dust collection box 16. The suction pipe 13 can deliver the suction force generated by the suction fan 14 to the inside of the dust collection box 12, so that the dust collection box 12 can absorb the dust during the shredding process, thereby reducing the impact of dust on the external environment. At the same time, the suction fan 14 can deliver the dust to the inside of the dust collection box 16 through the conveying pipe 15 for centralized collection, which facilitates the treatment of dust.
[0029] Reference Figure 5 and 6 As shown, two shredding support frames 24 are fixedly connected to the inner side of the shredder body 1. A shredding mechanism is installed inside the shredder body 1. The shredding mechanism includes a second motor 17. One side of the shredder body 1 is fixedly connected to the second motor 17 by screws. A first sprocket 18 is installed at the output end of the second motor 17. A chain 19 is provided on the outer side of the first sprocket 18. A second sprocket 20 is provided on the inner side of the chain 19. A rotating shaft 21 is inserted into the inner side of both the first sprocket 18 and the second sprocket 20. The second motor 17 drives the first sprocket 18 to rotate, so that the first sprocket 18 can be connected to the second sprocket 20 to rotate through the chain 19. This allows the two rotating shafts 21 to rotate simultaneously. The rotation of the rotating shafts 21 can drive the shredding blades 23 to move crosswise through multiple shredding discs 22, which facilitates better and stronger shredding of waste materials. The cross distribution between the multiple shredding blades 23 can ensure that the fiberglass waste is crushed into uniform particle size during the crushing process.
[0030] Working principle of this utility model: This utility model designs a shredding mechanism for a shredder, the specific structure of which is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation of various structures, when fiberglass needs to be shredded, the fiberglass is first placed into the shredder body 1 through the feed port on one side of the protective box 2. Then, the second motor 17 is driven, which drives the first sprocket 18 to rotate. The first sprocket 18 is then connected to the second sprocket 20 via the chain 19, which facilitates the rotation of the shaft 21 by the first sprocket 18 and the second sprocket 20. The two shafts 21 can drive the shredding blades 23 to rotate crosswise through multiple shredding discs 22. The tips of the shredding blades 23 can shred the fiberglass. When the second motor 17 rotates, the first motor 4 is started simultaneously, which drives the threaded rod 5 to rotate. The screw rod 5 drives the movable plate 6 downward through the screw thread. The two sliding grooves 10 can guide the movement of the movable plate 6, so that the movable plate 6 can drive the support rod 7 and the connecting rod 8 to move downward. This can continuously apply downward pressure to the fiberglass to be shredded, which can increase the contact area between the fiberglass and the shredding blade 23. At the same time, the suction fan 14 is started to generate suction force, which can be used to absorb the dust in the shredding process through the dust collection box 12. The filter screen 11 is used to block larger fragments. Then, the suction fan 14 transports the dust to the dust collection box 16 through the conveying pipe 15 for centralized collection. Finally, the shredded fiberglass fragments will be discharged through the discharge port at the bottom of the shredder body 1.
