JPH0263834A - Double belt press having wet scrubber - Google Patents

Abstract

PURPOSE:To efficiently wash the surface of a belt by providing a wet scrubber equipped with a discharge port of washing liquid and a rotary brush so as to surround the lowest point of the belt on the opposite side of a press. CONSTITUTION:A double belt press 1 is provided to the center part of a structure equipped with two sets of upper and lower endless belts which are constituted of two pieces of drum pulleys 9 and endless belt 2. A long-sized laminated material to be molded is pinched with the upper and lower belts and passed through a through-hole provided to the press 1 in the progressing direction of the belts. At the time of pass, the laminated material is pressurized, heated and molded. The belts dirtied by resin, etc., are passed through the insides of the washing tanks 3 provided to the lowest points of belts 2 in the opposite sides of the press 1 and receive washing liquid from the discharge holes 5 and are brushed by the rotary brushes 4. Both the upper and lower belts are pushed downward by the guide rollers 6 in the washing tanks 3 to form V-shapes and the downward slopes are formed to the central parts of the belts. Thereby washing effect of the rears of the belts are made remarkable.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a belt cleaning device for manufacturing double belt press continuous laminates.

[Conventional technology]

Conventionally, laminates or metal foil-clad laminates have been manufactured by a pressure and heat forming method using a multistage press. In this forming method, laminated plates and smooth metal plates (mirror plates) are alternately stacked in a multi-stage process. As the end plate is used repeatedly through molding cycles, laminate debris or dirt accumulates on its surface, resulting in the surface of the laminate becoming rough. Because of this problem, a cleaning device for the surface of the end plate must be installed in the pre-process of the multi-stage press.

In recent years, a double helt press method for continuous production of laminates has been used instead of a multistage press method.

In this device, the belt has a role equivalent to the end plate, so
It is absolutely necessary to incorporate a belt cleaning device into the double belt press.

Conventionally, there was a method of continuously forming long plates by curing unsaturated polyester on an endless belt.
33066. This example incorporates a device for cleaning the endless belt using a brushing method using a solvent and a rotating brush.

[Problem to be solved by the invention]

The surface condition of a laminate or metal foil-clad laminate manufactured by the double belt press method is largely related to the smoothness and cleanliness of the belt surface.

In order to improve the cleanliness, high-performance and highly efficient cleaning equipment is required. For this purpose, it is necessary to incorporate a belt cleaning device into the press body.

The present invention provides a high-performance, high-efficiency cleaning device that can be incorporated into a double helt press.

[Means to solve the problem] The present invention has a structure in which a rotating brush is used in a wet method.

Next, embodiments of the present invention will be described with reference to the drawings. Figure 1 shows
A double belt brace 1 is shown at the center of an endless belt structure of 21 Jl above and below, consisting of two drum pulleys 9 and an endless belt 2. The upper and lower belts pass through holes provided in the press l in the direction of belt movement, sandwiching the long laminated material to be formed, and during this passage, the laminated material is pressurized and heated to be formed. The belt contaminated with resin, etc. passes through the cleaning tank 3, and the rotating brush 4 receives the cleaning liquid from the cleaning liquid discharge hole 5.
Brushing is done by. The guide roll 6 in the cleaning tank 3 pushes both the upper and lower belts upward to form a V-shape, giving a downward slope to the center of the belt.

Figure 2 shows the same double belt press structure as in Figure 1, but with a two-type arrangement consisting of a primary cleaning tank 7 and a finishing cleaning tank 8, with the lowest end of the belt located in the primary cleaning tank. .

[Effect]

In the embodiment shown in FIG. 1, the cleaning liquid on the upper surface of the belt flows to the lowest end of the belt, making it easy to dispose of the liquid. Second
In the embodiment shown in the figure, the finishing cleaning liquid flows into the primary cleaning tank, but the primary cleaning tank does not flow into the finishing cleaning tank, so the cleaning effect is not deteriorated.

〔Effect of the invention〕

According to the present invention, cleaning efficiency is high because the cleaning device is incorporated into the endless belt press, processing of cleaning waste liquid is easy because the belt is sloped, and the cleaning effect is remarkable because the cleaning tank is of two types. It became.
