Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, specifically to a safe material feeding control mechanism for plastic production. Background Technology

[0002] In the plastics production process, feeding control mechanisms are widely used to process plastics. Plastics are a type of high molecular polymer that is lightweight, durable, and highly malleable. Microplastics, which are difficult to distinguish with the naked eye, permeate all aspects of daily life and can harm human health. There are many types of plastics, including polyethylene, polypropylene, and polyvinyl chloride. Feeding control mechanisms are also used in the plastics production process.

[0003] When using existing feeding control mechanisms, a feeding ramp is usually placed inside. The feeding ramp is fixedly installed inside the feeding hopper, which can slow down the feeding speed.

[0004] However, existing feeding control mechanisms have a fixed feeding ramp inside the hopper, making it impossible to adjust the feeding port. This also limits the ease of adjusting the feeding speed for different amounts of plastic granules. To address these issues, a safe feeding control mechanism for plastic production is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a safe feeding control mechanism for plastic production, which solves the problem in the prior art where the feeding sloping plate is fixedly installed inside the feeding hopper, making it impossible to adjust the feeding port.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safe feeding control mechanism for plastic production, comprising a feeding hopper, a pipe fixedly connected to the bottom of the feeding hopper, an L-shaped plate fixedly connected to the rear side of the outer wall of the pipe, a cylinder fixedly connected to the bottom of the inner wall of the L-shaped plate, a second U-shaped plate fixedly connected to the output end of the cylinder, a first support plate rotatably connected to the inner wall of the second U-shaped plate, a movable plate rotatably connected to one side of each of the two first support plates, a rack fixedly connected to one side of each of the two movable plates, a gear meshing with one side of each of the two racks, a transmission rod penetrating and fixedly connected to one side of each of the two gears, a feeding inclined plate fixedly connected to the outer ring of each of the two transmission rods, a movable block fixedly connected to the front side of each of the two movable plates, and an anti-blocking component provided on the left side of the outer wall of the pipe.

[0007] By adopting the above technical solution, the cylinder is started to work, which drives the second U-shaped plate to move, thereby causing the first support plate to rotate, which in turn drives the moving plate to move under the limit of the second guide rail, thereby driving the rack to move, which in turn drives the gear to rotate, thereby driving the feeding sloping plate to rotate, and adjusting the tilt angle of the feeding sloping plate.

[0008] As a further description of the above technical solution: the anti-clogging component includes a fixing plate, which is fixedly connected to the pipe. A motor is fixedly connected to the bottom of the fixing plate, and an eccentric wheel is fixedly connected to the output end of the motor. A second support plate is rotatably connected to one side of the eccentric wheel, and a reciprocating rod is rotatably connected to one side of the second support plate. Two connecting rods are fixedly connected to the outer ring of the reciprocating rod. A first U-shaped plate is fixedly connected to the right side of the outer wall of the pipe. A support rod is slidably connected through one side of the inner wall of the first U-shaped plate. One end of each of the two support rods passes through the pipe and is fixedly connected to a pressing plate. A spring is sleeved on the outer ring of each of the two support rods.

[0009] By adopting the above technical solutions, the anti-clogging component can reduce clogging during material feeding.

[0010] As a further description of the above technical solution: one end of each of the two transmission rods is rotatably connected to a pipe.

[0012] As a further description of the above technical solution: a second guide rail is fixedly connected to one side of the outer wall of the pipe, and a moving block is slidably connected to the inner wall of the second guide rail.

[0013] By adopting the above technical solution, when the moving block is moving, it will slide within the second guide rail.

[0014] As a further description of the above technical solution: two first guide rails are fixedly connected to the top of one side of the outer wall of the pipe, and racks are slidably connected to the inner walls of the first guide rails.

[0015] By adopting the above technical solution, the rack will slide within the first guide rail when it moves.

[0016] As a further description of the above technical solution: one end of each gear is rotatably connected to a limiting plate, and the limiting plate is fixedly connected to the pipeline.

[0017] By adopting the above technical solution, the limiting plate supports and limits the gear.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. The present invention provides a safe feeding control mechanism for plastic production, which, through a cylinder, a feeding sloping plate, a rack, and a gear, activates the cylinder to drive the second U-shaped plate to move, thereby causing the first support plate to rotate, which in turn causes the moving plate to move under the limit of the second guide rail, thereby causing the rack to move, which in turn causes the gear to rotate, thereby causing the feeding sloping plate to rotate. The tilt angle of the feeding sloping plate can be adjusted to facilitate the adjustment of the feeding speed, making it convenient to use.

[0024] 2. The present invention provides a safe feeding control mechanism for plastic production. Through a motor, a second support plate, a reciprocating rod, a support rod, a spring, and an extrusion plate, when feeding material, starting the motor will drive the eccentric wheel to rotate, which will then pull the reciprocating rod to move back and forth in the pipe. When the reciprocating rod contacts the second guide rail, it will move the second guide rail and compress the spring. When the reciprocating rod moves away, the spring will rebound, causing the pipe to sway slightly, which will assist in feeding material and reduce blockage. Attached Figure Description

[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 content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0033] Combination Figure 1 This utility model discloses a safe feeding control mechanism for plastic production, comprising a feeding hopper 1, with a pipe 2 fixedly connected to the bottom of the feeding hopper 1, allowing plastic to be directly fed into the feeding hopper 1 for safety. Both the motor 4 and the cylinder 8 are controlled by a controller. An L-shaped plate 7 is fixedly connected to the rear side of the outer wall of the pipe 2. Two transmission rods 17 are rotatably connected to the pipe 2 at one end. When the feeding inclined plate 16 rotates, the transmission rods 17 rotate on the pipe 2. A second guide rail 26 is fixedly connected to one side of the outer wall of the pipe 2, and the inner wall of the second guide rail 26 slides. A movable block 18 is connected. When the movable block 18 moves, it moves within the second guide rail 26. Two first guide rails 13 are fixedly connected to the top of one side of the outer wall of the pipe 2. When the rack 12 moves, it is limited by the first guide rail 13. The rack 12 is slidably connected to the inner wall of the first guide rail 13. One end of each of the two gears 15 is rotatably connected to a limit plate 14. When the gear 15 rotates, the limit plate 14 provides support and limitation. The limit plate 14 is fixedly connected to the pipe 2. An installation plate 6 is fixedly connected to the bottom of the outer wall of the pipe 2.

[0034] Combination Figure 2 and Figure 3 A cylinder 8 is fixedly connected to the bottom of the inner wall of the L-shaped plate 7. A second U-shaped plate 9 is fixedly connected to the output end of the cylinder 8. A first support plate 10 is rotatably connected to the inner wall of the second U-shaped plate 9. When the cylinder 8 works, it can push the second U-shaped plate 9 to move, and then drive the second guide rail 26 to rotate, so that the moving plate 11 moves. The two first support plates 10 are rotatably connected to one side of the moving plate 11. The two moving plates 11 are fixedly connected to one side of the rack 12. When the rack 12 moves, it can drive the gear 15 to rotate, and then drive the transmission rod 17 to rotate. The two racks 12 are meshed with the gear 15 on one side. The two gears 15 are penetrated and fixedly connected to the transmission rod 17 on one side. The two transmission rods 17 are fixedly connected to the outer ring of the two transmission rods 17. When the transmission rod 17 rotates, it can drive the feeding inclined plate 16 to rotate, thereby adjusting the tilt angle of the feeding inclined plate 16. The two moving plates 11 are fixedly connected to the front side of the moving plate 11. An anti-blocking component is provided on the left side of the outer wall of the pipe 2.

[0035] Combination Figure 2 , Figure 4 and Figure 5 The anti-blocking component includes a fixing plate 3, which is fixedly connected to the pipe 2. A motor 4 is fixedly connected to the bottom of the fixing plate 3. When the motor 4 works, it drives the eccentric wheel 5 to rotate, which in turn pulls the reciprocating rod 20 to move back and forth inside the pipe 2, thereby clearing the blockage inside the pipe 2. The output end of the motor 4 is fixedly connected to the eccentric wheel 5. A second support plate 19 is rotatably connected to one side of the eccentric wheel 5, and the reciprocating rod 20 is rotatably connected to one side of the second support plate 19. When the reciprocating rod 20 moves, it also drives the connecting rod 22 to move. Two connecting rods 22 are fixedly connected to the outer ring of the reciprocating rod 20. A first U-shaped plate 23 is fixedly connected to the right side of the outer wall. A support rod 24 is slidably connected through one side of the inner wall of the first U-shaped plate 23. When the reciprocating rod 20 moves, it will press against the extrusion plate 27. When the extrusion plate 27 is under force, the support rod 24 will slide and compress the spring 25. When the force on the extrusion plate 27 is removed, the spring 25 will rebound, causing the pipe 2 to shake. One end of the two support rods 24 passes through the pipe 2 and is fixedly connected to the extrusion plate 27. Springs 25 are fitted on the outer ring of both support rods 24. A limit frame 21 is fixedly connected to the left side of the outer wall of the pipe 2. The reciprocating rod 20 is slidably connected to the inner ring of the limit frame 21.

[0036] Working principle: When in use, the cylinder 8 is started, pushing the second U-shaped plate 9 to move, which drives the first support plate 10 to rotate. This causes the moving block 18 connected to the moving plate 11 to move to the upper limit of the second guide rail 26, thereby driving the rack 12 to move under the limit of the first guide rail 13. This drives the gear 15 to rotate, and then drives the feeding inclined plate 16 to adjust its angle, thereby adjusting the inclination of the feeding inclined plate 16 and controlling the size of the feeding opening. Then, the motor 4 is started, driving the eccentric wheel 5 to rotate, which pulls the reciprocating rod 20 to move under the limit of the limit frame 21. This causes the reciprocating rod 20 to move back and forth in the pipe 2, and the connecting rod 22 also moves with it, clearing the inside of the pipe 2. When the reciprocating rod 20 contacts the extrusion plate 27, it will squeeze the extrusion plate 27 to slide, compressing the spring 25. When the reciprocating rod 20 moves away from the extrusion plate 27, the spring 25 rebounds, which can cause the pipe 2 to vibrate slightly, assisting in feeding and reducing blockage.
