Description

Technical Field

[0001] The utility model belongs to the technical field of distributors, in particular to a distributor for a polyethylene sheet preparation device. Background Art

[0002] In the process of preparing polyethylene sheets, it is necessary to spread the powdered raw materials onto the mold. The currently used distributor includes a frame with a slot at the lower end, a storage hopper is arranged above the frame, and a distribution roller is arranged below the storage hopper. Both ends of the distribution roller are connected to the power mechanism through a reduction mechanism. There are scratches on the surface of the distribution roller, and baffles are arranged on the storage hoppers on both sides of the distribution roller. There is a certain gap between the baffle and the surface of the distribution roller. Of course, some baffles can also adjust the height, that is, adjust the gap between the baffle and the surface of the distribution roller, so as to adjust the distribution amount. The slot under the frame is stuck on the track of the polyethylene sheet preparation device. While the frame moves along the track, the power mechanism drives the distribution roller to rotate, and the polyethylene raw material leaks out from the gap between the baffle and the surface of the distribution roller. The above-mentioned distributor has the following defects: First, due to the high viscosity of the polyethylene raw material, when the raw material passes through the gap between the baffle and the surface of the distribution roller, the raw material is easily squeezed into blocks or sheets and adheres to the baffle, affecting the amount of material falling. In addition, due to the extrusion and attachment to the distribution roller, the friction of the distribution roller is reduced, and the amount of material falling is affected; second, the block or sheet raw material falls on the mold, resulting in uneven material spreading, affecting the quality of the board. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a distributor for a polyethylene sheet preparation device with uniform distribution and accurate distribution quantity.

[0004] In order to solve the above problems, the technical solution adopted by the distributor for the polyethylene sheet preparation device of the utility model is: it includes a frame with a slot at the lower end, a storage hopper is arranged above the frame, a distribution roller is arranged below the storage hopper, both ends of the distribution roller are connected to the power mechanism through a reduction mechanism, a strip-shaped distribution groove is arranged on the distribution roller along the axial direction, the extension line of the center line of the distribution groove intersects with the axis of the distribution roller, and a scraper is arranged in the storage hopper on the side of the distribution roller.

[0005] Its additional technical features are:

[0006] A vibration motor is arranged on the frame;

[0007] The two side edges of the material distributing groove coincide with the radial direction of the material distributing roller.

[0008] Compared with the prior art, the distributor for polyethylene sheet preparation device provided by the utility model has the following advantages: first, since it includes a frame with a slot at the lower end, a storage hopper is arranged above the frame, and a distribution roller is arranged below the storage hopper, both ends of the distribution roller are connected to the power mechanism through a reduction mechanism, a strip distribution groove along the axial direction is arranged on the distribution roller, and the extension line of the center line of the distribution groove intersects with the axis of the distribution roller, and a scraper is arranged on the storage hopper on the side of the distribution roller, the slot is clamped on the track of the polyethylene sheet preparation device, so that the distributor moves forward and backward along the track, and when the distributor moves forward, the power mechanism drives the distribution roller to rotate, and the raw materials in the storage hopper fall into the distribution groove. When passing through the scraper , the excess raw materials beyond the outside of the feeding trough are swept away, and when the feeding trough filled with raw materials is tilted downward or downward, the raw materials in the feeding trough fall onto the mold under the action of gravity. During the whole process, the raw materials are not squeezed, not easy to clump, and the feeding is more uniform and accurate; secondly, since a vibration motor is arranged on the frame, when the feeding trough is downward, the raw materials in the feeding trough fall off more thoroughly, avoiding the raw materials from adhering to the feeding trough, and also making it easier for the raw materials in the storage hopper to be filled into the feeding trough, which is more convenient to use and more accurate in feeding; thirdly, since the two sides of the feeding trough coincide with the radial direction of the feeding roller, that is, the feeding trough is wide outside and narrow inside, when the feeding trough is downward, the raw materials in the feeding trough are easier to fall.

[0013] The structure and use principle of the distributor for the polyethylene sheet preparation device of the utility model are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0014] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the schematic diagram of the structure of the distributor for the polyethylene sheet preparation device of the utility model comprises a frame 2 with a slot 1 at the lower end, a storage hopper 3 is arranged above the frame 1, a distribution roller 4 is arranged below the storage hopper 3, both ends of the distribution roller 4 are connected with the power mechanism 6 through a reduction mechanism 5, a strip distribution groove 7 is arranged on the distribution roller 4 along the axial direction, the extension line of the center line of the distribution groove 7 intersects with the axis of the distribution roller, and a scraper 8 is arranged on the storage hopper on the side of the distribution roller 4.

[0015] The card slot 1 is stuck on the track of the polyethylene sheet preparation device, so that the distributor moves forward and backward along the track. While the distributor moves forward, the power mechanism 6 drives the distribution roller 4 to rotate, and the raw materials in the storage hopper 3 fall into the distribution slot 7. When passing through the scraper 8, the excess raw materials beyond the outside of the distribution slot are swept away. When the distribution slot filled with raw materials moves diagonally downward or downward, the raw materials in the distribution slot 7 fall onto the mold under the action of gravity. During the whole process, the raw materials are not squeezed, not easy to agglomerate, and the distribution is more uniform and accurate.

[0016] A vibration motor 9 is arranged on the frame 2. When the material distribution trough 7 is downward, the raw materials in the material distribution trough 7 fall off more thoroughly, avoiding the raw materials from adhering to the material distribution trough 7. It also makes the raw materials in the storage hopper 5 more evenly distributed, and the raw materials can be better filled into the material distribution trough 7, which is more convenient to use and more accurate in distribution.

[0017] The material distributing trough 7 can be as Figure 3 The cross-section of the slot shown is rectangular, and the Figure 4 As shown, both side edges of the material distribution groove 7 coincide with the radial direction of the material distribution roller 4, that is, the material distribution groove is wide outside and narrow inside, and when the material distribution groove is downward, the raw materials in the material distribution groove fall more easily.

[0018] The protection scope of the present invention is not limited to the above-mentioned embodiments. As long as the structure is the same or similar to the structure of the distributor for the polyethylene sheet preparation device of the present invention, it falls within the protection scope of the present invention.
