Description

Technical Field

[0001] The utility model relates to the technical field of PE plastic pipe production, in particular to a feeding device for a PE plastic pipe production line. Background Technique

[0002] PE is polyethylene plastic, which is one of the most basic plastics. Plastic bags, food wraps, etc. are all made of PE. PE is polymerized from the monomer ethylene, and its manufacturing material is polyethylene. PE has excellent characteristics of resisting most chemicals used in life and industry. It has the characteristics of high strength, high temperature resistance, corrosion resistance, non-toxicity, and wear resistance. It is divided into medium-density polyethylene pipes and high-density polyethylene pipes. Due to its characteristics, PE materials are widely used in the field of water supply and drainage manufacturing. Because it does not rust, it is an ideal pipe to replace ordinary iron water supply pipes.

[0003] According to a disclosed feeding device for a PVC plastic pipe production line (Publication No.: CN214494566U), in the above application, the raw materials are mixed and stirred in a closed environment to avoid dust flying at the production site; the feeding is carried out by a screw conveyor. First, it reduces the labor intensity of workers, and second, the feeding efficiency is also relatively high.

[0004] However, in the above application, when feeding the mixed materials through a screw conveyor, not all the materials in the pit can enter the screw conveyor. The raw materials around the feeding end of the screw conveyor cannot enter the screw conveyor for feeding work, and the feeding quantity cannot be controlled. If too much material is fed at one time, the materials will accumulate on the production line, and in severe cases, overflow will occur, resulting in the dropping of materials.

The fourth gear 92 meshes with the rack 93. A rotating rod 96 is arranged on the surface of the fourth gear 92. The rotating rod 96 penetrates through the fourth gear 92, the second gear 83, the rotating cylinder 84, and the mixing tank 1, and the rotating rod 96 is fixedly connected to the fourth gear 92. A first connecting plate 94 is fixed to the bottom of the rotating rod 96. A second connecting plate 95 is fixedly connected to the inner wall of the mixing tank 1. Leakage holes are opened on the surfaces of the first connecting plate 94 and the second connecting plate 95. Four teeth are arranged on the surface of the third gear 90, and the four teeth are divided into two groups and are circumferentially arranged around the center of the third gear 90. Half of the teeth are arranged on the fourth gear 92. A ratchet wheel is arranged on the inner wall of the through hole 91. A ratchet pawl is arranged on the surface of the output shaft of the second motor 81. When the second motor 81 rotates in reverse, through the ratchet wheel and the ratchet pawl, the third gear 90 rotates, so that the third gear 90 reciprocally meshes with the rack 93 and the fourth gear 92, and the leakage holes of the first connecting plate 94 and the second connecting plate 95 can reciprocally be parallel. The materials can intermittently enter the conveyor housing 5 for feeding work, avoiding the phenomenon of excessive feeding and overflow.

[0024] The L-shaped plate 80 is fixed to the top of the mixing tank 1. The second motor 81 is fixed to the surface of the L-shaped plate 80. The output shaft of the second motor 81 penetrates through the mixing tank 1. The first gear 82 is rotatably connected to the top inner wall of the mixing tank 1. The output shaft of the second motor 81 penetrates through the first gear 82, and the output shaft of the second motor 81 is fixedly connected to the first gear 82. The second gear 83 is rotatably connected to the top inner wall of the mixing tank 1. The first gear 82 meshes with the second gear 83.

When the leakage holes of the first connecting plate 94 and the second connecting plate 95 coincide, the materials enter the discharge bin 3. At the same time, the solenoid valve 4 is opened, so that the materials enter the conveyor housing 5 through the inlet 6, and are discharged through the conveying spiral blade 11 and the outlet 10, so that the materials enter the feed inlet of the PE plastic pipe production line. When the third gear 90 does not mesh with the rack 93, at this time, the teeth of the third gear 90 mesh with the teeth of the fourth gear 92, and then drive the fourth gear 92 to rotate reversely and reset. At this time, the leakage holes of the first connecting plate 94 and the second connecting plate 95 are staggered, and at this time, the materials cannot enter the discharge bin 3. Then, when the second motor 81 continues to rotate reversely, the materials can enter the conveyor housing 5 intermittently for feeding work, avoiding the phenomenon of excessive feeding and overflow. At the same time, the inlet 6 of the conveyor housing 5 is located directly below the discharge bin 3, and the materials are not difficult to enter the conveyor housing 5.
