Description

Technical Field

[0001] This utility model relates to the field of plastic extrusion technology, specifically to a device for removing plastic extrusion precipitates. Background Technology

[0002] Globally, approximately 430 million tons of plastic are produced annually, more than two-thirds of which are single-use products that quickly become waste after use. Since the mid-20th century, the plastics chemical industry has experienced explosive growth, with a cumulative global production of approximately 9.2 billion tons of plastic, of which about 7 billion tons have become waste. Of this, only 8% of plastic waste is recycled, with the majority ending up in landfills or incinerated, and about 76% of the waste directly leaking into the environment.

[0003] Exudates accumulating at the die opening for extended periods can cause scratches on the finished product surface, affecting its appearance quality.5 Furthermore, the exudates may randomly detach and adhere to the product surface, leading to decreased product strength and increasing the risk of breakage.5 For example, in the production of plastic pipes, exudates can cause scratches on the pipe surface, leading to stress concentration and increasing the risk of pipe bursting.

[0004] If the extrusion tube cannot be driven to extrude the workpiece, manual operation may be required to complete the extrusion process. This is not only slow, but the frequency and force of manual operation are also difficult to maintain, resulting in low extrusion efficiency and failing to meet the needs of large-scale production.

[0005] To address the aforementioned problems, a device for removing plastic extrusion precipitates is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a device for removing plastic extrusion precipitates, which solves the problem in the prior art that the frequency and intensity of manual operation are difficult to maintain stably, resulting in low extrusion efficiency and failure to meet the needs of large-scale production.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for removing plastic extrusion precipitates, comprising a support leg, a grooved plate fixedly connected to the top of the support leg, a motor fixedly connected to the bottom of the grooved plate, a rotating plate fixedly connected to the output end of the motor, inclined rods rotatably connected to both ends of the rotating plate, a movable disk rotatably connected to one end of each inclined rod, uniformly distributed guide blocks fixedly connected to the bottom of the grooved plate, a movable block slidably connected to the outer wall of the guide block and fixedly connected to the movable disk, a movable plate fixedly connected to the top of the movable disk, a fixed disk fixedly connected to the top of the movable plate on the left side, an extrusion tube fixedly connected to the right side of the fixed disk, a connecting sleeve threadedly connected to the outer ring of the extrusion tube, a connecting ring fixedly connected to the top of the movable plate on the right side, and a drive assembly disposed to the left of the connecting ring.

[0008] By adopting the above technical solution, the rotating plate is driven by the motor to rotate, which in turn drives the inclined rod to rotate. The moving disk is guided and limited by the guide block and the sliding block. The connecting sleeve and the extrusion tube can extrude objects and extruded precipitates. The size of the connecting sleeve can be changed.

[0009] As a further description of the above technical solution: the driving component includes an arc-shaped guide rail, which is fixedly connected to the left side of the connecting ring, and a sliding block is slidably connected to the outer wall of the arc-shaped guide rail.

[0010] By adopting the above technical solution, the sliding block has a drive motor inside, which enables it to move and slide on the outer wall of the arc-shaped guide rail.

[0011] As a further description of the above technical solution: a connecting pipe is fixedly connected to the left side of the sliding block, and a flat nozzle is provided on the left side of the connecting pipe.

[0012] By adopting the above technical solution, compressed air is used to blow air, and the round nozzle of the copper tube is changed to a flat nozzle to increase the blowing force. Intermittent blowing is performed: blow for 5 seconds, stop for 30 seconds, and repeat the cycle.

[0013] As a further description of the above technical solution: a connecting frame is provided between the flat-nozzle tube and the connecting tube.

[0014] By adopting the above technical solution, the flat nozzle tube and the connecting tube are fixed by the connecting bracket.

[0015] As a further description of the above technical solution: the connecting frame is internally rotatably connected with a bidirectional threaded rod.

[0018] By adopting the above technical solution, the nut pair slides inside the connecting frame.

[0019] As a further description of the above technical solution: an arc-shaped ring is fixedly connected to the top of the nut assembly.

[0020] By adopting the above technical solution, the connecting pipe and the flat nozzle pipe are fixed by an arc ring.

[0021] As a further description of the above technical solution: a locking ring is provided inside the arc-shaped ring, and a limit plate is fixedly connected to the outer ring on the right side of the bidirectional threaded rod.

[0022] By adopting the above technical solution, the bidirectional threaded rod is controlled by the limiting plate and bolts.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This utility model provides a device for removing plastic extrusion precipitates. First, the motor drives the rotating plate to rotate. Then, the movement of the inclined rod pushes the moving disk to reciprocate linearly along the direction of the guide block. This causes the fixed disk and extrusion tube on the top of the left moving plate and the connecting ring on the top of the right moving plate to move synchronously. This enables the left extrusion tube to extrude the object, thus meeting the corresponding extrusion work requirements.

[0025] This utility model provides a device for removing plastic extrusion precipitates. When the bidirectional threaded rod is rotated, the nuts at both ends move in opposite directions within the connecting frame, thereby driving the arc ring and locking ring fixedly connected to the top of the nut pair to move. This adjusts the position and angle of the flat nozzle tube, and facilitates the fixing of the flat nozzle tube and adjustment of the air jet direction of the flat nozzle tube to adapt to different working requirements.

[0031] 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.

[0032] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Reference Figures 1-4 This utility model discloses a device for removing plastic extrusion precipitates, comprising a support leg 1 that provides stable support for the entire device. The top of the support leg 1 is fixedly connected to a grooved plate 2 to ensure the stability of the device. A motor 7 is fixedly installed at the bottom of the grooved plate 2, serving as a power source to provide power support for the operation of the device.

[0034] The output end of motor 7 is connected to rotating plate 8. When motor 7 starts, rotating plate 8 rotates accordingly. Both ends of rotating plate 8 are rotatably connected to inclined rods 9, and the other end of inclined rods 9 is rotatably connected to movable disk 23. Evenly distributed guide blocks 10 are also fixedly connected to the bottom of grooved plate 2. Movable blocks 11 are slidably connected to the outer wall of guide blocks 10, and movable blocks 11 are fixedly connected to movable disk 23. This structural design allows rotating plate 8 to rotate, causing inclined rods 9 to drive movable disk 23 to reciprocate linearly along the direction of guide blocks 10.

[0035] The top of the movable disk 23 is fixedly connected to the movable plate 3. In this embodiment, there are movable plates 3 on both the left and right sides. The top of the left movable plate 3 is fixedly connected to the fixed disk 4, and the right side of the fixed disk 4 is fixedly connected to the extrusion tube 5. The outer ring of the extrusion tube 5 is threaded with a connecting sleeve 6. The top of the right movable plate 3 is fixedly connected to the connecting ring 22, and a drive component is provided on the left side of the connecting ring 22.

[0036] In the drive assembly, an arc-shaped guide rail 12 is fixedly connected to the left side of the connecting ring 22, and a sliding block 13 is slidably connected to the outer wall of the arc-shaped guide rail 12. A connecting pipe 14 is fixedly connected to the left side of the sliding block 13, and a flat-nozzle pipe 15 is provided on the left side of the connecting pipe 14. A connecting bracket 18 is provided between the flat-nozzle pipe 15 and the connecting pipe 14.

[0037] The connecting frame 18 is internally connected to a bidirectional threaded rod 19. Both ends of the bidirectional threaded rod 19 are threadedly connected to nut pairs 20, and the nut pairs 20 are slidably connected to the connecting frame 18. The top of the nut pairs 20 is fixedly connected to an arc ring 16, and a locking ring 17 is provided inside the arc ring 16. The right outer ring of the bidirectional threaded rod 19 is fixedly connected to a limiting plate 21.

[0038] During actual installation and debugging, first place the support leg 1 on a stable working surface to ensure the device is stable. Install the groove plate 2 and the motor 7, and connect the power line of the motor 7. Install the rotating plate 8 at the output end of the motor 7, and connect the inclined rod 9, the moving plate 23, the moving block 11, and the guide block 10 in sequence to ensure that each connection part rotates flexibly and slides smoothly. Install the moving plates 3, the fixed plate 4, the extrusion tube 5, the connecting sleeve 6, and the connecting ring 22 on the left and right sides to ensure that all components are firmly connected.

[0039] For the drive assembly, the arc-shaped guide rail 12 is installed on the left side of the connecting ring 22, allowing the sliding block 13 to slide normally on the arc-shaped guide rail 12. The connecting pipe 14, the flat-nozzle pipe 15, and the connecting bracket 18 are installed, ensuring a tight connection. The bidirectional threaded rod 19, the nut pair 20, the arc-shaped ring 16, the locking ring 17, and the limit plate 21 are installed. The movement of the nut pair 20 when the bidirectional threaded rod 19 rotates is adjusted to ensure smooth movement of the arc-shaped ring 16 and the locking ring 17, thereby adjusting the position and angle of the flat-nozzle pipe 15.

[0040] Before the device is put into operation, the position and angle of the flat nozzle 15 need to be adjusted by rotating the bidirectional threaded rod 19 according to the actual working requirements. When the bidirectional threaded rod 19 rotates, the nut pairs 20 at both ends move towards or away from each other within the connecting frame 18, driving the arc ring 16 and locking ring 17 at the top of the nut pairs 20 to move, thereby adjusting and fixing the flat nozzle 15 so that its jet direction can adapt to different working requirements. After the preparation work is completed, the motor 7 is started. The motor 7 drives the rotating plate 8 to rotate, which in turn drives the inclined rod 9 to move, pushing the moving disk 23 to reciprocate linearly along the guide block 10, so that the extrusion tube 5 on the left moving plate 3 extrudes the object. At the same time, the flat nozzle 15 in the right drive assembly sprays gas through the connecting pipe 14, which can treat the precipitates generated during the plastic extrusion process and ensure the smooth progress of the plastic extrusion work.

[0041] Working principle: Start motor 7, and the output of motor 7 drives the rotating plate 8 to rotate. The inclined rods 9 rotatably connected to both ends of the rotating plate 8 will move with the rotation of the rotating plate 8. Since one end of the inclined rod 9 is rotatably connected to the moving disk 23, and the moving disk 23 is fixedly connected to the moving block 11 sliding on the outer wall of the guide block 10, the movement of the inclined rod 9 can push the moving disk 23 to reciprocate linearly along the direction of the guide block 10. The fixed disk 4 fixedly connected to the top of the left moving plate 3 and the extrusion tube 5 connected to the right side of the fixed disk 4 will move with the moving plate 3. The connecting ring 22 connected to the top of the right moving plate 3 will also move synchronously. The extrusion tube 5 on the left... The object is extruded, the arc-shaped guide rail 12 is fixed to the left side of the connecting ring 22, the sliding block 13 slides on the outer wall of the arc-shaped guide rail 12, and the gas is sprayed out through the connecting pipe 14 and the flat nozzle pipe 15. The flat nozzle pipe 15 is installed, and the bidirectional threaded rod 19 is rotated. The nut pair 20 connected to the outer ring of the two ends of the bidirectional threaded rod 19 will move in opposite directions or away from each other along the bidirectional threaded rod 19 in the connecting frame 18. The arc-shaped ring 16 fixedly connected to the top of the nut pair 20 will drive the locking ring 17 to move, thereby adjusting the position and angle of the flat nozzle pipe 15 for easy fixing.
