Description

Waste thin and soft plastic product chopping and recycling device

Technical Field

The utility model relates to an abandonment plastics degradation recovery technical field, concretely relates to thin soft plastic products of abandonment cut up recovery unit.

Background

Waste plastics, which are a type of waste that has a great environmental impact, are generally disposed of for recycling or degradation. Because the plastic products have different shapes and sizes, the waste plastics are generally subjected to treatment steps such as cleaning, thermal cracking and the like after being uniformly chopped. Most of the plastic products on the market are made into products with thin and soft texture and relatively large area, such as plastic bags, plastic tarpaulins, plastic bubble films and the like. In the recovery process of the product, the product is required to be firstly cut up, and then the cut-up product is subjected to thermal cracking and other treatments.

At present, Chinese patent No. CN106493879A discloses a device for cutting up waste plastic garbage for decoration, which is driven by a transmission structure such as a gear, a belt pulley and the like and sent to a cutter for cutting up. The transmission structure in the structure is generally more suitable for plastic products with fixed shapes, and if the transmission structure is used for transmitting thin, soft and large-area plastic bags and other products, the flexible plastic products are easy to be intertwined, even are clamped and embedded in a transmission mechanism and the like, and are gradually intertwined and influence the operation of equipment in the rotating process of the wheels.

SUMMERY OF THE UTILITY MODEL

Therefore, the to-be-solved technical problem of the utility model lies in overcoming the easy defect of tangling of soft plastics product among the prior art to a thin soft plastics goods of abandonment cuts up recovery unit is provided.

The heating wall comprises a heat conduction surface facing the interior of the pipe body and used for being in contact with the plastic product, and an electric heating wire attached to one surface, deviating from the plastic product, of the heat conduction surface, and the electric heating wire is communicated with an external power supply to generate heat.

The conveying wall comprises a wall surface with a notch and a transmission body positioned at the notch of the wall surface, and the running direction of the transmission body is the same as the conveying direction of the plastic products.

The part of the transmission body, which is contacted with the plastic product, protrudes out of the plane of the wall surface.

The notch of the wall surface is in an I shape.

The heating channel is arranged obliquely or vertically.

The feed inlet is a combination of a cylinder and a cone, the large end of the cone is connected with the cylinder, and the small end of the cone is connected with the heating channel.

And a piston pushing device for pushing the plastic products to move towards the conveying direction is arranged on the inner wall of the cylindrical part of the feeding hole, and a piston rod of the piston pushing device points to the conical part of the feeding hole.

The utility model discloses technical scheme has following advantage:

1. since the thin and soft plastic products are generally large in area and long in length and are easily twisted together, when the conventional gear-driven or wheel-shaped cutter is used for cutting, the plastic products are easily twisted together or twisted on a rotating part of equipment such as the gear or wheel-shaped cutter. In this scheme, before the cutting, heat thin soft plastics earlier, because thin soft plastics is heated the deformation easily, consequently is being heated the back and is agglomerating easily, and subsequent cutting of being convenient for is difficult for winding the cutter.

2. What be used for driving thin soft plastics in this scheme is transmission body, is the large tracts of land contact with thin soft plastics, compares in equipment such as gear and can reduce the winding possibility.

3. The piston pushing device at the feeding hole can effectively push the thin soft plastic into the heating channel, so that the thin soft plastic can be continuously output.
