Description

Technical Field

[0001] This utility model relates to the field of PE pipe production technology, and in particular to a feeding device for PE pipe production. Background Technology

[0002] In the plastics processing industry, especially for the production of PE (polyethylene) pipes, the feeding device is one of the key links in the entire production line. Its main function is to uniformly and stably transport plastic granules to the extruder or other processing equipment.

[0003] Currently, feeding devices on the market typically include gravity feeding, screw feeding, and vibration feeding. Although each of these feeding devices has its own characteristics, in practical applications, some types of plastic granules are prone to clumping due to changes in humidity and temperature or long-term storage. Existing feeding devices lack an effective clumping mechanism and cannot break up the clumped material in time, thus affecting the continuity and quality of subsequent processing. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing feeding devices lack an effective agglomeration mechanism, which makes it impossible to break up agglomerated materials in a timely manner, thus affecting the continuity and quality of subsequent processing. Therefore, this invention proposes a feeding device for PE pipe production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding device for PE pipe production includes a hopper with a discharge port to allow rapid input of plastic granules. A motor is fixedly mounted on the hopper, and the output end of the motor passes through the hopper and is connected to a rotating shaft via a coupling. Scrapers are equidistantly mounted on the rotating shaft. The device also includes a clump-breaking section coaxially arranged with the rotating shaft. A bushing is fixedly mounted on the inner top wall of the hopper. A corrugated groove is formed at one end of the rotating shaft located within the bushing. A positioning pin adapted to the corrugated groove is fixedly mounted on the clump-breaking section. When the rotating shaft rotates, the positioning pin moves along the corrugated groove, causing the clump-breaking section to generate radial movement relative to the rotating shaft, thereby breaking up agglomerated materials.

[0007] To help break up clumps of material, preferably, the clump-breaking section includes a connecting block slidably mounted on the bushing, a positioning pin fixedly mounted on the connecting block, and equidistantly distributed breaking rods fixedly mounted on the end of the connecting block located outside the bushing.

[0008] In order to be able to bend or deform when encountering greater resistance, thereby avoiding damage to the equipment, the breaking rod is further elastic.

[0009] In order to effectively disperse agglomerated materials into smaller particles through compression, shearing and other methods, the end of the crushing rod is provided with a clump-breaking head that can contact the material. The clump-breaking head applies pressure to the material as the rotating shaft rotates and moves radially with the positioning pin.

[0010] In order to evenly disperse the material after the agglomeration treatment and prevent the material from piling up or clumping again, a dispersing plate is further fixedly installed on the rotating shaft, and the dispersing plate is located below the crushing rod.

[0011] To increase the contact area between the material and the air, which is beneficial for material flow and drying in subsequent processing, the dispersion plate is further shaped like an umbrella.

[0012] In order to effectively push the material to the subsequent processing equipment, a guide pipe is further installed at the bottom of the hopper, and a spiral rod located inside the guide pipe is installed at the bottom of the rotating shaft.

[0013] Compared with the prior art, this utility model provides a feeding device for PE pipe production, which has the following advantages:

[0014] 1. The feeding device for PE pipe production, through the synergistic effect of the positioning pin and the corrugated groove, enables the breaking head to accurately perform radial movement, apply effective pressure to the agglomerated material, and significantly improve the breaking efficiency.

[0015] 2. The feeding device for PE pipe production features an equidistant distribution design of the crushing rod and its shredding head, ensuring that the material is uniformly processed throughout the feeding process and avoiding problems of insufficient or excessive processing in certain areas.

[0016] 3. The feeding device for PE pipe production features an umbrella-shaped dispersion plate design that significantly improves the dispersion performance of materials, prevents secondary agglomeration, ensures the uniformity and flowability of materials, and improves feeding efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0024] Example:

[0025] Reference Figures 1-4 A feeding device for PE pipe production includes a hopper 1 with a spacious discharge port 101 to allow rapid feeding of plastic granules. A motor 2 is fixedly mounted on the hopper 1, and the output end of the motor 2 passes through the hopper 1 and is connected to a rotating shaft 3 via a coupling to ensure synchronous rotation. Scrapers 4 are equidistantly mounted on the rotating shaft 3. During rotation, the scrapers 4 continuously contact and push the material to prevent it from adhering to the wall of the hopper 1 and to promote uniform material flow. The device also includes a clump-breaking section 5, coaxially mounted with the rotating shaft 3. The device includes a bushing 6 fixedly installed on the inner top wall of the hopper 1. A corrugated groove 301 is provided at one end of the rotating shaft 3 located inside the bushing 6. A positioning pin 7 adapted to the corrugated groove 301 is fixedly installed on the clump breaking part 5. Preferably, the corrugated groove 301 is sinusoidal in shape to provide a continuous and uniform radial force to the positioning pin 7, ensuring the effective operation of the clump breaking part 5. When the rotating shaft 3 rotates, the positioning pin 7 moves along the corrugated groove 301, causing the clump breaking part 5 to generate radial movement relative to the rotating shaft 3, which is used to break up agglomerated materials.

[0026] When using this feeding device for PE pipe production, the operator starts the motor 2. The output end of the motor 2 is connected to the rotating shaft 3 via a coupling to ensure synchronous rotation. As the rotating shaft 3 rotates, the scrapers 4, which are equidistantly mounted on it, also begin to operate. The scrapers 4 continuously contact and push the material, preventing it from adhering to the wall of the hopper 1 and promoting uniform material flow, providing good conditions for subsequent processing. When the rotating shaft 3 rotates, the positioning pin 7, which is fixedly mounted on the breaking section 5, moves along the trajectory of the corrugated groove 301. Since the corrugated groove 301 is sinusoidal in shape, the positioning pin 7 will undergo a series of periodic radial displacements. The radial movement of the positioning pin 7 forces the breaking section 5 to produce radial movement relative to the rotating shaft 3, directly acting on the existing agglomerated material, effectively dispersing the agglomerated material into smaller particles. After the breaking process, the plastic particles become looser and more uniform. At this time, the scrapers 4 continue to push the material downward until it smoothly enters the twin-screw extruder or other processing equipment.

[0027] The shredder unit 5 includes a connecting block 501 slidably mounted on a bushing 6, which can slide axially inside the bushing 6. A locating pin 7 is fixedly mounted on the connecting block 501 and is adapted to the wave groove 301 on the rotating shaft 3. When the rotating shaft 3 rotates, the locating pin 7 moves along the wave groove 301, forcing the connecting block 501 and the entire shredder unit 5 to produce radial movement relative to the rotating shaft 3. There are also equidistantly distributed crushing rods 502, which are fixedly mounted on the end of the connecting block 501 located outside the bushing 6. In particular, the crushing rods 502 are elastic and can bend or deform when encountering greater resistance, thereby avoiding damage to the equipment.

[0028] When the feeding device starts working, the motor 2 starts and drives the rotating shaft 3 to rotate through the coupling. As the rotating shaft 3 rotates, the corrugated groove 301 on it also rotates synchronously. Since the positioning pin 7 is tightly engaged with the corrugated groove 301, when the rotating shaft 3 rotates, the positioning pin 7 is forced to move along the trajectory of the corrugated groove 301. This movement causes the connecting block 501 to not only rotate with the rotating shaft 3, but also to undergo radial displacement due to the shape of the corrugated groove 301. The radial movement of the connecting block 501 is directly transmitted to the crushing rod 502. As the rotating shaft 3 continues to rotate, the crushing rod 502 continuously impacts or cuts the agglomerated material. Since the crushing rod 502 is elastic, when the crushing rod 502 encounters harder agglomerated material, it can bend or deform to avoid damage caused by excessive impact force. At the same time, the elastic design allows the crushing rod 502 to apply additional shearing force during the process of restoring its original shape, further helping to break up the agglomerated material.

[0029] Furthermore, the end of the crushing rod 502 is provided with a clump-breaking head 503 that can contact the material. When the rotating shaft 3 rotates, the clump-breaking head 503 applies pressure to the material with the radial movement of the positioning pin 7.

[0030] The radial movement of the connecting block 501 is directly transmitted to the crushing rod 502, which in turn drives the clump breaking head 503. As the rotating shaft 3 continues to rotate, the clump breaking head 503 continuously enters and exits the material flow, impacting or squeezing the agglomerated material at different angles and positions, and effectively dispersing the agglomerated material into smaller particles through compression, shearing and other methods.

[0031] A dispersing plate 8 is fixedly installed on the rotating shaft 3. The dispersing plate 8 is located below the crushing rod 502. In particular, the dispersing plate 8 is umbrella-shaped.

[0032] The umbrella-shaped dispersion plate 8 helps to evenly disperse the material after the agglomeration treatment, preventing the material from piling up or clumping again. The umbrella-shaped structure increases the contact area between the material and the air, which is beneficial to the material flow and drying in subsequent processing.

[0033] The bottom of the hopper 1 is equipped with a guide pipe 9, which serves as a transition channel for materials from the hopper 1 to subsequent processing equipment. The bottom of the rotating shaft 3 is equipped with a screw rod 10 located inside the guide pipe 9, which can effectively push the materials to subsequent processing equipment, such as a twin-screw extruder, to ensure the continuity and stability of material conveying.

[0034] When the feeding device starts working, the motor 2 starts and drives the rotating shaft 3 to rotate through the coupling. As the rotating shaft 3 rotates, the scrapers 4, which are equidistantly installed on it, also start to operate, continuously contacting and pushing the material to prevent the material from sticking to the wall of the hopper 1 and promote the uniform flow of the material. The positioning pin 7 moves along the corrugated groove 301, forcing the breaking section 5 to produce radial movement. The crushing rod 502 and its breaking head 503 apply pressure to the agglomerated material, effectively breaking up the agglomerated material. The umbrella-shaped dispersing plate 8 evenly disperses the material after the agglomeration treatment, preventing the material from accumulating or agglomerating again, and increasing the contact area between the material and the air, which is beneficial to the material flow and drying in the subsequent processing. The material after the agglomeration and dispersion treatment falls into the guide pipe 9. The screw rod 10 at the bottom of the rotating shaft 3 rotates inside the guide pipe 9. Using the propulsive action of the screw blades, the material is continuously and stably pushed to the subsequent processing equipment, such as a twin-screw extruder. This not only ensures the continuity of material conveying, but also prevents the material from clogging in the guide pipe 9, ensuring the smooth progress of the entire feeding process.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
