Cooling mechanism applied after processing formation of agricultural plastic mulching films

Abstract

The invention discloses a cooling mechanism applied after processing formation of agricultural plastic mulching films. The cooling mechanism comprises a base and multiple cooling rollers. The cooling rollers are arranged at the top of the base. The top of the base is provided with multiple stand columns. A top plate is arranged on the stand columns and provided with a cold air blower. A movable box is arranged on each stand column and can move in the axis direction of the corresponding stand column, and each movable box can rotate around the axis of the corresponding stand column. The movable boxes are connected with the cold air blower. A second air guiding pipe is further arranged on the side face of each movable box. Each second air guiding pipes communicates with the interior of the corresponding movable box. By means of the cooling mechanism, when the films are cooled, the situation that impurities adhere to the films, so that quality of the films is affected can be avoided; meanwhile, cooling treatment can be conducted on two faces of each film at the same time; and in addition, compared with traditional cooling rollers, the cooling effect of the cooling rollers is improved.

Description

technical field [0001] The invention relates to an agricultural film processing device, in particular to a cooling mechanism after the agricultural film is processed and formed. Background technique [0002] Agricultural film is also called film plastic, including mulch (also called agricultural mulch), the main component of which is polyethylene, which is used to cover farmland to increase ground temperature, preserve soil moisture, promote seed germination and rapid growth of seedlings; The role of weed growth. During the processing of the plastic film, the material is first melted, then shaped, cooled, and finally the film is rolled up by the receiving mechanism. At present, the cooling process of the film mainly adopts a long transfer table between the film forming machine and the winding mechanism, and cools it through the air in the room, so that not only the cooling speed is slow, but also the long transfer table occupies It has certain requirements for the factory ...

AI Technical Summary

Problems solved by technology

At present, the cooling process of the film mainly adopts a long transfer table between the film forming machine and the winding mechanism, and cools it through the air in the room, so that not only the cooling speed is slow, but also the long transfer table occupies It has certain requirements for the factory building; or a number of cooling rolls are set between the film forming machine and the winder, and the cooling liquid is passed into the cooling rolls, and the cooling liquid is used to reduce the heat transferred from the film to the surface of the cooling rolls. To achieve the effect of film cooling, but in this way, the surface of the film attached to the cooling roller cools faster, while the other side of the film cools slowly, which will affect the decrease in film transparency, and due to the cooling of the two sides The rate is different, so the shrinkage rate of the two sides is also different, so it is easy to cause the film to curl and affect the use of the film; at the same time, during the cooling process of the film, impurities such as dust flying in the workshop are easy to adhere to the surface of the film, after the film is cooled , the impurities attached to the film are difficult to remove, which affects the normal use of the film
