Description

Technical Field

[0001] The utility model belongs to the technical field of waste recycling, and particularly relates to a PBAT film edge waste recycling device. Background Art

[0002] Polylactic acid (PLA) is a relatively mature biodegradable resin at present, which has the characteristics of transparency, easy processing and complete biodegradability. Moreover, the synthetic raw materials are derived from natural materials, making it an ideal material to replace petroleum-based resins such as polyethylene. During the production and processing of plastic films, the two sides of the formed plastic film will have uneven edges. When winding, the plastic film will be trimmed, and the trimmed edge film needs to be recycled.

[0003] The recycling devices currently in use have relatively single functions. Their role is only to centrally store the films, but the distance between the waste materials is relatively large, which results in limited single storage space of the recycling device. And the recycled films need to be melted into liquid at high temperature for reprocessing, which increases the recycling steps of the films and makes the recycling and processing process of the films overly cumbersome. Summary of the Utility Model

[0004] The utility model provides a PBAT film edge waste recycling device, aiming to solve the problem of the cumbersome and complex process of recycling PBAT film edge waste at present.

[0005] The utility model is realized as follows: a PBAT film edge waste recycling device includes a recycling box; a feeding groove is installed at the top of the recycling box, a limiting ring is installed at the top of the inner wall of the recycling box, a fixing frame is placed on the upper end of the limiting ring, a heating frame is installed on the lower side of the fixing frame, the heating frame is composed of a plurality of rings with different diameters and is in a pot shape as a whole, an air outlet groove is opened on the side of the recycling box, a fan is installed on the outer wall of the recycling box corresponding to the air outlet groove, and the air outlet of the fan is connected to an exhaust pipe. A receiving box is placed at the bottom end of the inner part of the recycling box, and the receiving box is located directly below the heating frame.

[0006] Preferably, a baffle is installed on the inner wall of the recycling box, the lower side of the baffle is inclined, and the air outlet groove is inclined.

[0007] Preferably, a limiting column is installed below the fixing frame, a slot adapted to the size of the limiting column is opened on the upper surface of the limiting ring, a conductive block is installed at the bottom of the limiting column, a conductive plate is installed at the bottom of the slot of the limiting ring, the recycling box supplies power to the conductive plate through a power cord, and two groups of pull rings are installed at the top of the fixing frame.

[0008] Preferably, a rocker is installed inside the fixing frame through a fixing rod, a scraper is installed at the bottom of the rocker, and the scraper is attached to the upper surface of the heating frame.

[0009] Preferably, two sets of notches are opened at the bottom of the recycling box, pulleys are installed around the bottom of the material receiving box, and the pulleys slide into the bottom notches of the recycling box.

[0010] Preferably, an inner side plate is installed on the inner wall of the material receiving box. The inner side plate is made of metal for conducting electricity, and a power connection port connected to the inner side plate is installed on the side of the material receiving box.

[0011] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

[0012] By installing a blower on the side of the recycling box, negative pressure can be generated inside the recycling box, so that the feeding chute has an adsorption function. The blower discharges the inhaled gas into the waste gas pipe, preventing the odor gas generated by the melting of the film from emitting outward through the feeding chute.
