Description

Technical Field

[0001] This application relates to the field of PVC plastic pipe processing technology, and in particular to a feeding device for manufacturing PVC plastic pipes. Background Technology

[0002] PVC plastic pipes are widely used in construction, water supply and drainage, chemical and other fields. They have good corrosion resistance, easy processing, economy and long service life. During the production of PVC plastic pipes, PVC granules need to be fed into the hopper of an extruder. Through the rotation of the screw and heating, the PVC granules are melted and plasticized into a uniform melt.

[0003] Currently, in pipe manufacturing, PVC granules are generally fed directly into the feed pipe and then into the extruder for processing and extrusion. However, the preparation of PVC pipes usually involves mixing the main material and auxiliary materials before they enter the extruder. Direct feeding will cause some dust entrained in the PVC to enter the extruder and be extruded together, which leads to a decrease in quality. Therefore, a feeding device for PVC plastic pipe manufacturing has been designed to solve the above-mentioned problems. Utility Model Content

[0004] To address this problem, this application provides a feeding device for manufacturing PVC plastic pipes.

[0005] The feeding device for manufacturing PVC plastic pipes provided in this application adopts the following technical solution:

[0006] A feeding device for manufacturing PVC plastic pipes includes a feeding box, with feed pipes fixedly connected to both sides of the feeding box, and a dust extraction fan fixedly installed in the upper part of the feeding box.

[0007] The material shaking component, installed inside the feeding box, is used to lift the material into the air to assist the dust collection fan in dust extraction;

[0008] The material shaking assembly includes a lifting cylinder, which is fixedly installed on the upper end of the feeding box. The output end of the lifting cylinder is rotatably connected to a screw rod, and the lower end of the screw rod is fixedly connected to a material shaking disc.

[0009] Preferably, the shaking disc is in the shape of a conical disc, and the sidewall of the shaking disc is arc-shaped.

[0010] Preferably, the spiral rod is threadedly connected to a spiral ring, and support rods are fixedly connected to both sides of the spiral ring, with the upper end of the support rods fixedly connected to the end wall of the feeding box.

[0011] Preferably, a sliding rod is fixedly connected to the lower end of the shaking disc, an installation tube is slidably connected to the lower end of the sliding rod, and stirring rods are fixedly connected to both sides of the installation tube.

[0012] Preferably, the lower end of the mounting pipe is rotatably connected to a support frame, and the two sides of the support frame are fixedly connected to the inner sidewalls of the feeding box.

[0013] Preferably, a collection frame is fixedly installed on the output end of the upper side of the dust collector, and the collection frame is fixedly installed on the upper end of the feeding box.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] In this invention, the lifting cylinder, shaking disc, and dust-collecting fan are designed to suspend and disperse the PVC granules after they enter the feeding box, making it easier for the dust-collecting fan to suck up dust and lighter impurities for dust removal. Furthermore, the spiral rod, spiral ring, mounting pipe, and stirring rod are designed to pre-mix the main and auxiliary materials before they enter the extruder, facilitating mixing and extrusion after entering the extruder.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a feeding device for manufacturing PVC plastic pipes. (Refer to...) Figure 1-3 A feeding device for manufacturing PVC plastic pipes includes a feeding box 1, feeding pipes 2 are fixedly connected to both sides of the feeding box 1, a dust suction fan 3 is fixedly installed in the upper part of the feeding box 1, a collection frame 4 is fixedly installed at the output end of the upper side of the dust suction fan 3, and the collection frame 4 is fixedly installed in the upper part of the feeding box 1 for collecting the dust and impurities sucked out.

[0022] A material shaking component for assisting dust collection is provided in the feeding box 1. The material shaking component includes a lifting cylinder 5, which is fixedly installed on the upper end of the feeding box 1. The output end of the lifting cylinder 5 is rotatably connected to the screw rod 6, and the lower end of the screw rod 6 is fixedly connected to the material shaking disc 8.

[0023] By adopting the above technical solution, the shaking disc 8 is in the shape of a conical disc, and the side wall of the shaking disc 8 is arc-shaped, such as... Figure 3 As shown, the curved surface facilitates the movement of materials to the upper side and the dispersal of materials.

[0024] By adopting the above technical solution, in order to facilitate the material entering the extruder for mixing and extrusion, a spiral ring 7 is threadedly connected to the spiral rod 6, and support rods 71 ​​are fixedly connected to both sides of the spiral ring 7. The upper end of the support rod 71 is fixedly connected to the end wall of the feeding box 1, and the lower end of the shaking disc 8 is fixedly connected to the slide rod 9. The lower end of the slide rod 9 is slidably connected to the mounting pipe 10, and the two sides of the mounting pipe 10 are fixedly connected to the stirring rod 11.

[0025] The screw rod 6 rotates, which in turn drives the shaking disc 8 to rotate. The shaking disc 8 then drives the slide rod 9 and the mounting tube 10 to rotate, causing the stirring rod 11 on the mounting tube 10 to rotate and stir the material during rotation, so that the main material and auxiliary material are mixed and can be mixed and extruded after entering the extruder.

[0026] The lower end of the mounting pipe 10 is rotatably connected to the support frame 12. The two sides of the support frame 12 are fixedly connected to the inner sidewall of the feeding box 1, which serves to fix the mounting pipe 10 so that the mounting pipe 10 can only rotate and does not rise with it.

[0027] The implementation principle of the feeding device for manufacturing PVC plastic pipes according to this application embodiment is as follows: PVC granules, the main material and auxiliary material, are fed into the feeding pipes 2 on both sides respectively. During this period, the lifting cylinder 5 is activated, causing the lifting cylinder 5 to drive the shaking disc 8 at the lower end of the screw rod 6 to move rapidly up and down. The screw rod 6 drives the shaking disc 8 to rise and fall, which pushes the material entering the feeding box 1 from the feeding pipe 2 to rise. Due to the rapid rise and fall of the shaking disc 8, the material is suspended in the air after being raised, thereby dispersing the material entering the feeding box 1. At the same time, the dust suction fan 3 is activated, allowing the dust suction fan 3 to absorb the dust mixed in with the material. The dispersed material makes it easier for the dust suction fan 3 to suck out dust and lighter impurities, facilitating the dust removal treatment of the material.

[0028] When the screw rod 6 is lifted and lowered by the lifting cylinder 5, it will be affected by the screw ring 7 connected to the thread, causing the screw rod 6 to rotate and drive the shaking disc 8 to rotate. The shaking disc 8 then drives the slide rod 9 and the mounting tube 10 to rotate, causing the stirring rod 11 on the mounting tube 10 to rotate and stir the material during rotation, so that the main material and auxiliary material are mixed and can be mixed and extruded after entering the extruder.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
