A water-permeable film production device

Abstract

The invention provides a novel water-through transparent film production device and solves the problems that the peeling points are unstable, the water temperature in a water tank is non-uniform, impurities in water flow are adhered to the surface of the film, the water marks are formed in the surface of the film, and the transparency of the water-through transparent film is influenced in the conventional device. The scheme adopted by the invention is as follows: a first guide roller and a second guide roller are arranged inside the water tank; a dragging roller is arranged at the rear part of the water tank; an upper pressing roller is arranged on the dragging roller; a horizontally-arranged water distributor is arranged inside the water tank above the position between the first guide roller and the second guide roller; a horizontally-arranged plate cooler is arranged inside the water tank above the water distributor; a plurality of water overflowing openings are uniformly distributed around the top end of the water tank at intervals; a water receiving groove around the water tank is formed in the outer side wall of the water tank under the water overflowing openings; the bottom end of the water receiving groove communicates with a water storage barrel via a water returning pipe; the lower end of the water storage barrel is communicated with the water distributor via a water pump; the upper pressing roller is a foam rubber roller.

Description

technical field [0001] The invention relates to a PVC water-permeable film production device, in particular to a water-permeable film production device. Background technique [0002] In the production process of PVC calendered transparent film, there is a production method that can quickly improve its transparency by passing water. It needs a special pool for producing water-permeable film. The traditional pool is equipped with two guide rollers in the stainless steel pool. With inlet and outlet, such as figure 1 As shown, the calendered film 1 is peeled off from the roller surface of the lower roller 2 of the calender under the action of film gravity and the traction of the traction device, passes through the water under the guidance of the guide roller 3 in the pool, and enters the next machine, and the high-temperature film enters the water Its transparency is greatly improved. The disadvantages of the traditional pool are: 1. The two guide rollers have no transmission, ...

AI Technical Summary

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a water-permeable film production device, which can effectively solve the problem of unstable peeling point, uneven water temperature in the pool, and impurities in the water flow adhered to the surface of the film in the traditional device. , there are water marks on the surface of the membrane, etc., which affect the transparency of the water-permeable membrane, etc.
