Abstract

The invention discloses a cooling and shaping device for PVC film production. The cooling and shaping device comprises a cooling roller, elastic adjusting assemblies, a transmission mechanism, a moving plate and a cooling box. A film inlet and a film outlet are respectively formed in two transverse sides of the top of the cooling box. The cooling roller and the elastic adjusting assemblies are alllocated in the cooling box. The six elastic adjusting assemblies comprise connecting shafts, mounting frames, first connecting plates, guide rods, second connecting plates and elastic pieces. The connecting shafts are rotationally arranged on the mounting frames, the mounting frames are arranged on the guide rods in a sliding mode, and the first connecting plates, the guide rods and the second connecting plates are connected in sequence. Two ends of each elastic piece are respectively connected with the corresponding mounting frame and the corresponding first connecting plate. A moving driving mechanism for driving the moving plate to move in the vertical direction is arranged on the cooling box. The cooling box is connected with a cooling mechanism. The transmission mechanism comprises belt wheel and a belts. According to the cooling and shaping device for PVC film production, a PVC film can be guaranteed to be always kept in a tensioned and stretched state in the conveying process,all positions of the PVC film can be fully and evenly cooled, and the cooling quality is high.

Description

technical field [0001] The invention relates to the technical field of PVC film production, in particular to a cooling and shaping device for PVC film production. Background technique [0002] The main component of PVC is polyvinyl chloride, which is light yellow, translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. And lower than polypropylene, there will be whitening at the inflection. The production line of PVC is generally composed of rolling machine, printing machine, back coating machine and cutting machine, mainly through the direct stirring of the rolling machine, the rotation of the roller and high temperature rolling to produce a film with a thickness of only 0.3mm-0.7mm . [0003] The cooling rolls...
