Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to an energy-saving and environmentally friendly plastic processing machine. Background Technology

[0002] Plastic crushing is a common processing step in plastic processing. The plastic crushed by a plastic crusher can be used as a raw material for production. Plastic crushers are a type of energy-saving and environmentally friendly plastic processing machine.

[0003] For example, patent CN213107680U discloses a crushing and processing device for waste plastic recycling, including a box body, an inlet on the left side of the box body, and a conveyor belt on the left side of the inlet.

[0004] With the above configuration, the existing crushing and processing device for waste plastic recycling, by setting a downward-moving arc-shaped baffle, can reduce the movement space of the plastic, allowing it to be quickly crushed within the crushing device, thus improving crushing efficiency. Furthermore, the arc of the baffle is adapted to the arc of the first set of crushing rollers, and crushing blades are set on the surface of the arc-shaped baffle. As the arc-shaped baffle moves downward, it can cooperate with the first set of crushing rollers to perform initial crushing of the plastic, reducing the pressure on the first set of crushing rollers during the crushing process and preventing the crushing blades from jamming. The second set of crushing rollers located below the first set of crushing rollers can perform a second crushing of the plastic, improving the efficiency and quality of plastic crushing. However, the existing plastic recycling crushing and processing device has the following drawbacks during operation:

[0005] In the above-mentioned device, the filter plate is set above the discharge port, but the filter plate is not vibrated. Therefore, when a large amount of crushed waste plastic falls, the crushed plastic will clog the filter plate and accumulate, affecting the normal discharge and screening of the device and reducing the crushing efficiency. Utility Model Content

[0006] The present invention aims to provide an energy-saving and environmentally friendly plastic processing machine, which is mainly used to solve the technical problem that the crushed plastic tends to accumulate inside the device in the existing technology.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An energy-saving and environmentally friendly plastic processing machine includes a feeding hopper, a crushing box, and a discharge pipe. Crushing rollers are symmetrically and rotatably connected through the inner side wall of the crushing box. A filter plate is slidably connected to the inner side wall of the crushing box. A driving assembly is provided on the outer side wall of the crushing box. The driving assembly is used to drive two crushing rollers to rotate in opposite directions simultaneously. A contact assembly is symmetrically and rotatably connected through the outer side wall of the crushing box. A transmission assembly is rotatably connected to the outer side wall of the crushing box.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When using this device, the plastic to be crushed is first fed into the crushing chamber through the feed hopper. Then, the drive assembly is started, which simultaneously drives two crushing rollers to rotate in opposite directions. The plastic is crushed by the counter-rotating crushing rollers. The crushed plastic will fall onto the top of the filter plate and be screened by the filter plate. While the filter plate is screening the crushed plastic, the transmission assembly is started, which drives the contact assembly. The contact assembly causes the filter plate to slide up and down along the inner wall of the crushing chamber, thus speeding up the screening process of the plastic.

[0011] 2. Beneficial effects:

[0012] Existing technologies can reduce the movement space of plastics by setting downward-moving arc-shaped baffles, thereby enabling the plastics to be crushed quickly within the crushing device and improving crushing efficiency. However, existing technologies suffer from the problem that the crushed plastics tend to accumulate inside the device. This solution addresses this issue by setting a drive component that allows two crushing rollers to rotate in opposite directions simultaneously. This allows the plastics to be crushed by the crushing rollers rotating in two directions. The transmission component facilitates the operation of the contact component. During the operation of the contact component, the filter plate slides up and down along the inner wall of the crushing chamber, thereby accelerating the plastic screening rate through the up-and-down movement of the filter plate.

[0013] Preferably, the inner wall of the crushing chamber has two symmetrical rectangular grooves. A connecting block is slidably connected to the inner wall of the rectangular groove. The end of the connecting block is fixedly connected to the side wall of the filter plate. A spring is fixedly connected to the bottom of the connecting block. The lower end of the spring is fixedly connected to the lower side wall of the rectangular groove. During the operation of the contact component, the contact component pushes the filter plate upward, causing the filter plate to drive the connecting block to slide upward along the inner wall of the rectangular groove. During this process, the spring is stretched. When the contact component no longer abuts against the filter plate, the filter plate automatically resets under the action of the stretched first spring. As the contact component operates, the filter plate slides up and down along the inner wall of the crushing chamber, thus increasing the plastic screening rate.

[0014] Preferably, the drive assembly includes gears symmetrically rotatably connected to the outer wall of the crushing chamber, with the two gears meshing with each other. The two gears are respectively fixedly connected to the ends of the two crushing rollers. A first motor is fixedly connected to the outer wall of the crushing chamber, and the output end of the first motor is fixedly connected to the end of one of the gears. When the device is in use, the first motor is started, which drives one of the gears to rotate, and then drives the other gear to rotate through the one gear. During the rotation of the two gears, the two crushing rollers are driven to rotate, thereby realizing the crushing of plastic.

[0015] Preferably, the contact assembly includes symmetrically penetrating and rotatably connected rotating rods to the inner wall of the crushing chamber. Abutment blocks are symmetrically fixed to the outer wall of the rotating rods, with the tips of the abutment blocks contacting the bottom of the filter plate. When in use, the transmission assembly is activated, simultaneously driving the two rotating rods to rotate. During this rotation, the abutment blocks rotate, causing their tips to contact the filter plate. This causes the filter plate to slide upwards along the inner wall of the crushing chamber, pulling the connecting block along with it. During this process, the spring is stretched. When the tips of the abutment blocks no longer contact the bottom of the filter plate, the stretched spring causes the filter plate to automatically move downwards. As the rotating rods rotate, the filter plate slides up and down along the inner wall of the crushing chamber, thus increasing the plastic screening rate.

[0016] Preferably, the transmission assembly includes transmission wheels symmetrically rotatably connected to the outer wall of the crushing chamber. Two transmission wheels are fixedly connected to the ends of two rotating rods respectively. A belt is fitted on the outer wall of the two transmission wheels. A second motor is fixedly connected to the outer wall of the crushing chamber. The output end of the second motor is fixedly connected to the outer wall of one of the transmission wheels. When it is necessary to rotate the two rotating rods simultaneously, the second motor is started, which drives one of the transmission wheels to rotate. Then, one of the transmission wheels drives the other transmission wheel to rotate, thereby achieving the purpose of rotating the two transmission wheels simultaneously. Finally, during the rotation of the two transmission wheels, the two rotating rods are driven to rotate respectively, thereby achieving the purpose of rotating the two rotating rods simultaneously.

[0017] Preferably, a guide plate is fixedly connected to the inner wall of the lower end of the crushing box, which facilitates the discharge of the screened plastic through the discharge pipe.

[0018] Preferably, the outer wall of the crushing box located at the filter plate is equipped with a protective door, and a handle is fixedly connected to the outer wall of the protective door. When there is a large plastic on the top of the filter plate that cannot be filtered, the protective door can be opened to remove the large plastic for secondary crushing.

[0025] 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.

[0026] like Figure 1-5As shown, an energy-saving and environmentally friendly plastic processing machine includes a feeding hopper 1, a crushing box 2, and a discharge pipe 3. Crushing rollers 11 are symmetrically connected and rotatably connected through the inner wall of the crushing box 2. A filter plate 12 is slidably connected to the inner wall of the crushing box 2. A drive assembly is provided on the outer wall of the crushing box 2. The drive assembly includes gears 6 symmetrically rotatably connected to the outer wall of the crushing box 2, with two gears 6 meshing with each other. The two gears 6 are respectively fixedly connected to the ends of two crushing rollers 11. A first motor 8 is fixedly connected to the outer wall of the crushing box 2, and the output end of the first motor 8 is fixedly connected to the end of one of the gears 6. The plastic to be crushed is first fed into the crushing box 2 through the feeding hopper 1. The first motor 8 is then started, utilizing the first... Motor 8 drives one of the gears 6 to rotate, which in turn drives the other gear 6 to rotate. During the rotation of the two gears 6, the two crushing rollers 11 rotate, thus achieving the crushing of the plastic. The drive assembly is used to drive the two crushing rollers 11 to rotate simultaneously in opposite directions. A contact assembly is symmetrically and rotatably connected through the outer wall of the crushing chamber 2. The contact assembly includes a rotating rod 14 symmetrically and rotatably connected through the inner wall of the crushing chamber 2. A contact block 17 is symmetrically fixedly connected to the outer wall of the rotating rod 14, and the tip of the contact block 17 abuts against the bottom of the filter plate 12. Two rectangular grooves 13 are symmetrically formed on the inner wall of the crushing chamber 2, and a connecting block 16 is slidably connected to the inner wall of the rectangular grooves 13. The end of the connecting block 16 is fixedly connected to the side wall of the filter plate 12. A spring 18 is fixedly connected to the bottom of the connecting block 16. The lower end of the spring 18 is fixedly connected to the lower side wall of the rectangular groove 13. During the rotation of the two rotating rods 14, the abutment block 17 is driven to rotate. During the rotation of the abutment block 17, the tip of the abutment block 17 abuts against the filter plate 12, causing the filter plate 12 to drive the connecting block 16 to slide upward along the inner side wall of the crushing box 2. During this process, the spring 18 is stretched. When the tip of the abutment block 17 no longer abuts against the bottom of the filter plate 12, the filter plate 12 automatically moves downward under the action of the stretched spring 18. As the rotating rods 14 rotate, the filter plate 12 slides up and down along the inner side wall of the crushing box 2. This increases the plastic screening rate. A transmission assembly is rotatably connected to the outer wall of the crushing chamber 2. The transmission assembly includes two transmission wheels 7 symmetrically rotatably connected to the outer wall of the crushing chamber 2. The two transmission wheels 7 are fixedly connected to the ends of two rotating rods 14, respectively. A belt 9 is fitted onto the outer wall of the two transmission wheels 7. A second motor 10 is fixedly connected to the outer wall of one of the transmission wheels 7. When the filter plate 12 screens the crushed plastic, the second motor 10 is activated, driving one of the transmission wheels 7 to rotate. This, in turn, drives the other transmission wheel 7 to rotate, thus achieving simultaneous rotation of both transmission wheels 7.Finally, as the two transmission wheels 7 rotate, they drive the two rotating rods 14 to rotate, thus achieving the goal of simultaneous rotation of the two rotating rods 14.

[0027] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0028] In use, the plastic to be crushed is first fed into the crushing chamber 2 through the feed hopper 1. The first motor 8 is started, driving one of the gears 6 to rotate, which in turn drives the other gear 6 to rotate. During the rotation of the two gears 6, the two crushing rollers 11 are driven to rotate, thus crushing the plastic. The crushed plastic falls to the top of the filter plate 12 for screening. While the filter plate 12 is screening the crushed plastic, the second motor 10 is started, driving one of the drive wheels 7 to rotate, which in turn drives the other drive wheel 7 to rotate, thus achieving simultaneous rotation of both drive wheels 7. The purpose of the movement is to drive the two rotating rods 14 to rotate during the rotation of the two transmission wheels 7. During the rotation of the two rotating rods 14, the contact block 17 rotates. During the rotation of the contact block 17, the tip of the contact block 17 contacts the filter plate 12, causing the filter plate 12 to drive the connecting block 16 to slide upward along the inner wall of the crushing box 2. During this process, the spring 18 is stretched. When the tip of the contact block 17 no longer contacts the bottom of the filter plate 12, the filter plate 12 automatically moves downward under the action of the stretched spring 18. As the rotating rod 14 rotates, the filter plate 12 slides up and down along the inner wall of the crushing box 2, thereby increasing the screening rate of plastic. Finally, the screened plastic is discharged through the discharge pipe 3 through the guide plate 15.
