Abstract

PURPOSE:To provide a durable, continuous molding unit requiring no replacement of seal material and the like by pressurizing from both sides a pair of belts transferring the material to be molded being sandwiched between them and molding the said material during transferring. CONSTITUTION:The faces are arranged to face each other so as to form the opposedly facing sections each other on each of a couple of belts 11a and 11b. The material to be molded 4 is sandwiched between the opposing faces 12a and 12b and transferred. The said opposing sections are sandwiched between the upper and lower sides by the plate-type pressurizing platens 21a and 21b, by which the material to be molded being sandwiched between the said opposing faces 12a and 12b is press molded continuously. The sheets 22a and 22b made of Teflon and the like as the slipping material are applied to the contact faces of the belts 11a and 11b with the pressurizing platens 21a and 21b respectively. By the said preparation, the belts 11a and 11 slide and move between the pressurizing platens 21a and 21b smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a continuous press molding apparatus that can continuously mold objects.

[Background technology]

A continuous method using a double belt method is used to obtain a laminate by continuously pressure-molding a laminate obtained by laminating a predetermined number of sheets of a resin-impregnated base material in the form of a strip wound into a roll. Conventionally, in this double belt type continuous press forming apparatus, a pair of belts ll'a and Il'b are attached to each other's surfaces 12'a, as shown in FIG.
, 12'b, the object to be formed 4' is sandwiched between them and they move in the same direction.

Opposing surfaces 12'a, 12'b of belts ll'a, ll'b
The molded object 4 sandwiched between the belts lla, 11
'b, and is guided into the pressurizing chamber 21' filled with a pressurizing medium P' such as air or oil, so that the molded object 4' is continuously press-molded by the pressurizing medium P'. It has become.

However, this continuous press molding apparatus had the following problems. A sealing material 3 is provided at the belt entrance/exit of the pressurizing chamber 21' to prevent the pressurized medium P' from leaking.
1'a and 31"b are easily worn out by the movement of the belt 11'a + Il"b, which tends to cause medium leakage (problem of not being able to obtain stable pressure, sealing materials 31'a, 31' The problem is that the replacement work of item (b) is troublesome.Furthermore, when oil is used as the pressure medium, there is also the problem that the device gets dirty and it takes time and effort to clean it.

[Purpose of the invention]

In view of the above circumstances, it is an object of the present invention to provide a continuous press molding apparatus that does not require replacement work of sealing materials and is equipped with a pressurizing means that has excellent durability.

[Disclosure of the invention]

In order to achieve such an object, the present invention includes a pair of belts that transport the object to be molded while sandwiching the object therebetween, and pressurizes these belts from both sides to form the object to be formed during the transfer. A continuous press molding apparatus equipped with a pressurizing means, characterized in that the pressurizing means is constituted by a press plate that sandwiches the molded article being transferred from above and below together with the belt. The gist is:

The present invention will be explained in detail below with reference to the drawings showing one embodiment thereof.

As shown in FIG. 1, the continuous press molding apparatus A according to the present invention includes a pair of belts lla and llb and a pressure means 2. In this pair of belts 11a and llb,
Opposing portions are provided such that their surfaces face each other. These bells l-113,llb are arranged to advance in the same direction in this opposing portion. The object to be molded 4 is placed between the opposing surfaces 12a and 12b of the opposing portions.
is pinched and moved. This opposing portion is sandwiched from above and below by plate-shaped pressure plates 21a and 21b serving as pressurizing means 2, so that the molded object sandwiched between the opposing surfaces 12a and 12b of the opposing portion is continuously formed. It is designed to be press-molded. This pressure plate 2
12.21b, the upper pressure plate 21a is fixed, and the lower pressure plate 21b is supported by the cylinder type elevating means 3 so that it can be raised and lowered freely. It is now possible to change the pressing force. Pressure 121a.

Sheets 22a and 22b made of Teflon or the like and having a thickness of about 111 mm are pasted as slipping materials on the surfaces of the belts 21b that come into contact with the belts lla and llb, respectively. Therefore, the belts lla and llb are
It is designed to slide effortlessly between the two.

The slip material is not limited to Teflon sheets as long as it has a small coefficient of friction and excellent wear resistance. Furthermore, if it is desired to provide a pressure cushion layer, the thickness of the slip material may be increased.

The continuous press molding apparatus according to the present invention is not limited to the above embodiment.

Belts are designed based on thermal conductivity, friction coefficient, etc.
Preferably, it is made of steel. Further, the belt is generally an endless belt, and a pair of endless belts are arranged vertically facing each other so that they rotate at the same speed and in opposite directions, but the invention is not limited to this.

〔Effect of the invention〕

Since the continuous press molding apparatus of the present invention is configured as described above, there is no need to replace the sealing material or the like. In addition, there is no oil stains and the pressurizing means has excellent durability.
Maintenance and management of the equipment becomes much easier. Since pressure can be applied roughly and stably, the quality of molded products is also stable.
