[0001] This utility model relates to the field of waste plastic recycling technology, specifically a feeder for waste plastic recycling. Background Technology

[0002] Waste plastic recycling refers to the process of reprocessing and reusing waste plastics through specific technologies, aiming to achieve resource recycling.

[0003] Waste plastic recycling feeders are specialized equipment used for conveying, lifting, and preliminary processing in the plastic recycling process. They mainly automate the conveying of waste plastics to subsequent processing stages, uniformly transporting raw materials such as plastic granules and powders to the equipment to avoid accumulation or material interruption and ensure continuous processing. However, when using existing feeders, they cannot screen and crush larger particles in the conveyed plastic granules, resulting in larger plastic granules being conveyed to subsequent processing stages, affecting the efficiency of recycling plastic granules in subsequent processes. Utility Model Content

[0004] The purpose of this utility model is to provide a feeder for recycling waste plastics, so as to solve the problem mentioned in the background art that when the feeder is used, it cannot screen and crush the larger particles in the conveyed plastic granules, so that the plastic granules mixed with larger particles are conveyed to the subsequent processing stage, which affects the efficiency of the subsequent process of recycling plastic granules.

[0024] 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.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A feeder for recycling waste plastics includes:

[0027] The body includes conveyor 1, which is an existing product and is not considered a technical protection point of this application. Therefore, it will not be described in detail here.

[0028] The crushing and discharging mechanism includes a discharge chute 2, which is fixedly connected to the surface of the conveyor 1 for discharging plastic granules. A limiting groove 21 is fixedly connected inside the discharge chute 2 for connecting a limiting rod 22. The limiting rod 22 is movably connected to the surface of the limiting groove 21 to limit the vibration position of the screening disc 23. The screening disc 23 is fixedly connected to the surface of the limiting rod 22 for screening the plastic granules. A mounting plate 24 is fixedly connected to the surface of the screening disc 23 for connecting a vibration motor 25. The vibration motor 25 is fixedly connected to the surface of the mounting plate 24 to drive the screening disc 23 to vibrate. A first drive motor 26 is installed inside the discharge chute 2 to drive the crushing roller 27 to rotate. The crushing roller 27 is rotatably connected to the surface of the first drive motor 26 for crushing larger plastic granules. A first connecting shaft 28 is fixedly connected inside the discharge chute 2 for connecting the crushing roller 27.

[0029] Furthermore, the limiting grooves 21 are evenly distributed in four groups inside the discharge trough 2, and the limiting rods 22 are evenly distributed in four groups on the surface of the screening disc 23. The four groups of limiting grooves 21 are used to connect the four groups of limiting rods 22, thereby ensuring the stability of the screening disc 23 during vibration screening.

[0030] Furthermore, the mounting plates 24 are symmetrically distributed in two sets on the surface of the screening disc 23. The screening disc 23 is internally and movably connected to the discharge chute 2 via the vibrating motor 25. The limiting rod 22 is movably connected to the surface of the screening disc 23 and the limiting groove 21. The two sets of mounting plates 24 are used to connect the two sets of vibrating motors 25. The two sets of vibrating motors 25 are controlled and started by the same servo driver to ensure that the two sets of vibrating motors 25 start synchronously. The start of the vibrating motor 25 drives the screening disc 23 to vibrate, thereby vibrating and screening the discharged particles. At the same time, the limiting rod 22 vibrates at the limiting groove 21 to limit the vibration position of the screening disc 23.

[0031] Furthermore, the first drive motors 26 are arranged in two sets of staggered symmetrical distribution inside the discharge trough 2, and the first connecting shafts 28 are arranged in two sets of staggered symmetrical distribution inside the discharge trough 2. The two sets of first drive motors 26 are controlled and started by the same servo driver to ensure that the two sets of first drive motors 26 start synchronously. The staggered symmetrical distribution of the two sets of first drive motors 26 and the first connecting shafts 28 can make the two sets of crushing rollers 27 rotate in opposite directions, thereby crushing the larger plastic particles screened out by the screening disc 23.

[0032] Furthermore, the crushing roller 27 is rotatably connected to the surface of the first drive motor 26 and the first connecting shaft 28. When the two sets of first drive motors 26 are started, they drive the two sets of crushing rollers 27 to rotate synchronously in opposite directions, thereby crushing larger plastic particles, which are then discharged through the discharge chute 2.

[0033] Furthermore, the uniform feeding mechanism includes a feeding hopper 3, which is fixedly connected to the surface of the conveyor 1 for feeding plastic granules. An anti-clogging cone hopper 31 is fixedly connected inside the feeding hopper 3 to prevent plastic granules from clogging the feeding hopper 3. A protective box 32 is fixedly connected to the surface of the feeding hopper 3 to protect the second drive motor 33. The second drive motor 33 is installed inside the protective box 32 to drive the conveying roller 34 to rotate. The conveying roller 34 is rotatably connected to the surface of the second drive motor 33 for uniformly feeding plastic granules. A cylindrical groove 35 is opened on the surface of the conveying roller 34 for conveying plastic granules. A second connecting shaft 36 is fixedly connected inside the feeding hopper 3 for connecting the conveying roller 34.

[0034] Furthermore, the anti-clogging cone 31 consists of two parts: one part is a cone and the other part is a cross-shaped support. The anti-clogging cone 31 is designed to disperse the plastic particles falling into the feed hopper 3, thus preventing the particles from clumping together and clogging the feed hopper 3.

[0035] Furthermore, six sets of cylindrical grooves 35 are evenly distributed on the surface of the conveying roller 34. The conveying roller 34 is rotatably connected to the surface of the second drive motor 33 and the second connecting shaft 36. When the second drive motor 33 starts, it drives the conveying roller 34 to rotate. The plastic particles fall into the cylindrical grooves 35 and are then conveyed downward into the conveyor 1 through the rotation of the conveying roller 34.

[0036] Working principle: When using conveyor 1, the second drive motor 33 is started first to drive the conveying roller 34 to rotate, and the plastic particles fall into the cylindrical groove 35. Then, the plastic particles are conveyed downward into the conveyor 1 through the rotation of the conveying roller 34. Then, the vibration motor 25 is started to drive the screening disc 23 to vibrate, thereby vibrating and screening the discharged particles. At the same time, the limiting rod 22 vibrates at the limiting groove 21 to limit the vibration position of the screening disc 23. The two sets of first drive motors 26 are started to drive the two sets of crushing rollers 27 to rotate synchronously in opposite directions, thereby crushing the larger plastic particles, and then discharging them through the discharge chute 2.
