Description

Technical Field

[0001] The utility model relates to the technical field of PVC pellet production feeding equipment, and particularly relates to a feeding equipment for PVC pipe production. Background Art

[0002] PVC modified material is a modified material composed of polyvinyl chloride resin as the main base material, plasticizer, stabilizer, coloring agent, ultraviolet absorber, filler, processing aid, etc. Common PVC pellet products in life, such as the bullets used in toy guns, are made of PVC material.

[0003] The patent with publication number CN218173596U discloses an efficient PVC pellet production feeding equipment. By starting the second motor to lift the feeding pipe and rotate along the support plate, the purpose of locally adjusting the height of the discharge port can be achieved. And by starting the third motor to drive the disc to rotate, through the connection of the adjusting mechanism, the purpose of rotating the feeding pipe can be achieved. However, when the number of raw material particles in the feeding pipeline is large at the same time during the use of this equipment, it is easy for the particles to get stuck in the gap between the feeding mechanism and the inner wall of the pipeline due to pushing during transportation, resulting in equipment jamming and blocking failures. For this reason, we propose a feeding equipment for PVC pipe production. Content of the Utility Model

[0025] One end of the feeding rack 7 far away from the transfer pipeline 5 is connected through and communicated with the side wall of a return material pipeline 13, a bottom partition board 11 is arranged at the inner bottom end of the return material pipeline 13, a screw feeding rod 12 for feeding is installed at the top end of the bottom partition board 11, the bottom end of the screw feeding rod 12 passes through the bottom partition board 11 and is installed at the power output end of a driving motor 10, an inclined feeding pipe 14 is connected through and communicated with the side wall of the top end of the return material pipeline 13, and one end of the inclined feeding pipe 14 far away from the return material pipeline 13 is connected through and communicated with the side wall of an integrated feeding bin 2.

[0026] During use, a feeding device is used to avoid the problem that the equipment is stuck in the gaps of the feeding screw due to a large number of raw material particles and small volume during the material conveying process, which causes the material conveying mechanism to be stuck, can improve the overall service life of the equipment, and can effectively reduce the occurrence of faults inside the pipeline, reduce the operation of maintaining the equipment, and a return material mechanism is used to return the screened granular raw materials back into the material conveying pipeline 1 through the pipeline.

[0027] As shown in the figure, the top end of the material conveying pipeline 1 is connected and communicated with the integrated feeding bin 2 through a pipeline.

[0028] During use, the recycled material and the input raw materials are fed into the conveying pipeline 1 by integrating the feeding bin 2.

[0029] As shown in the figure, protective material baffles 9 for preventing the splashing of rubber particles are fixedly connected to both sides of the feeding belt 8.

[0030] During use, the protective material baffles 9 are used to prevent the raw material particles from popping out and falling off the feeding belt 8.

[0035] The working principle and usage process of the present utility model: First, PVC raw material particles are introduced into the feed hopper at the top end of the integrated feeding bin 2, and then pass through the integrated feeding bin 2 and enter the interior of the conveying pipeline 1. They are input from the other end through the feeding screw inside the conveying pipeline 1 into the production equipment. During the conveying process, part of the raw material particles fall into the auxiliary feeding bin 3 through the bottom sieve, and then pass through the connecting member 4 and fall along the feeding plate 6 at the bottom end of the connecting pipe 5 onto the surface of the feeding belt 8 inside the feeding frame 7. They are conveyed by the feeding belt 8 to the recycled material pipeline 13 on the other side.

Subsequently, the threaded feeding rod 12 operates through the driving motor 10, passes through the bottom partition plate 11 to drive the threaded feeding rod 12 to rotate and scoop up the raw material particles, and then rises along the feeding channel and the recycled material pipeline 13 to the top end. Subsequently, through the side wall at the top end of the recycled material pipeline 13, they enter the inclined feeding pipe 14 with a through side wall through particle accumulation and extrusion, and finally slide into the integrated feeding bin 2. The on-off of the integrated feeding bin 2 can be controlled by adjusting the valve to prevent further damage caused by continuous feeding when the equipment is blocked. Then, it continues to be input into the conveying pipeline 1 for feeding. During the usage process, after the raw materials are input, by closing the baffle on the bottom end of the conveying pipeline 1, it is ensured that the raw materials can completely enter the production equipment through the pipeline.
