Description

Compound sheet flattening frock of multilayer

Technical Field

The utility model belongs to the technical field of radium-shine material preparation, concretely relates to compound sheet flattening frock of multilayer.

Background

The laser material is a three-layer composite structure of a PET electrochemical aluminum film, composite glue and a PVC film. In the thermal compounding process, the glue is heated to react, and the three layers are fused together; at this stage, due to the action of heat, the difference of internal stress generated by the orientation of the molecular chains in the three layers is large, so that the product is bent towards a PVC (polyvinyl chloride) surface, and the bent product has the defects of paper jam, printing dislocation and the like when being printed and used. There is therefore a need for improvements in the degree of flattening of multi-layer composite sheets prior to shipment.

In the traditional leveling equipment, a material in a roll shape passes through a heating roller, a bending force in the opposite direction is given to the material to offset the internal stress of the material, and in addition, the whole process is carried out in a heating state, so that the flatness of the material cannot rebound again after the material is heated. However, the traditional equipment has high cost and complex operation and control, and only a single set of equipment can be connected with the previous production process and then can be continuously heated, but multiple equipment cannot be simultaneously carried out; meanwhile, the traditional equipment needs to perform other quality control after the leveling process, and cannot obtain finished products meeting customer requirements.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the technical problem that exists among the prior art and provide a simple structure reasonable, with low costs, the effectual multilayer composite sheet flattening frock of flattening.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a multilayer composite sheet leveling tool comprises an oven, wherein a support is arranged on a storage plate of the oven, a composite material with a certain thickness is arranged on the support, the composite material is divided into a plurality of layers with equal thickness, and each layer of composite material comprises a plurality of bent composite sheets; pressing plates are arranged among the composite materials of each layer and at the top end and the bottom end of the composite materials; the area of the pressure plate is larger than that of the composite material; a plurality of pressing blocks are uniformly arranged above the pressing plate on the uppermost layer.

Further, each layer of composite material includes 100 curved composite sheets of the same size.

Further, the thickness of all composites does not exceed 700mm at the most.

Further, the number of briquettes was 16 and each briquette weighed 10 kg.

The utility model has the advantages and positive effects that:

the utility model discloses a radium-shine combined material that the briquetting equals a plurality of thickness is pressed and is established on the support of thing board is put to the oven to combined material divide into a plurality of layers according to same thickness and separates with the steel sheet, and every layer of combined material includes the composite sheet of a plurality of bendings. The whole composite material is pressed for a long time with load at a medium and low temperature in the oven, and after treatment, the flatness of the product is greatly improved and the product can be normally used by customers.

Compared with the traditional large-scale roller heating leveling equipment, the technology has the advantages of simple structure, low cost, simple and safe operation, low energy consumption and obvious effect, the same tool can be repeatedly used, and multiple groups of tools can simultaneously operate; and the finished product can be obtained after the working procedure is finished, which is very beneficial to quality control.

Description of the drawings:

fig. 1 is a schematic view of the leveling tool of the present invention.

Wherein: 1. an oven; 11. a storage plate; 2. a support; 3. pressing a plate; 4. a composite material; 5. and (7) briquetting.

Detailed Description

The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; rather than all embodiments. Based on the embodiment of the utility model; all other embodiments obtained by a person skilled in the art without making any inventive step; all belong to the protection scope of the utility model.

As shown in fig. 1, the embodiment provides a multilayer composite sheet leveling tool, which includes an oven 1, a square iron support 2 is arranged on an object placing plate 11 of the oven 1, a plurality of layers of pressing plates 3 with the same size are arranged on the support 2 at equal intervals, and composite materials 4 with the same thickness are arranged between adjacent pressing plates 3; the area of the press plate 3 is larger than that of the composite material 4; a plurality of pressing blocks 5 are uniformly arranged above the pressing plate 3 on the uppermost layer; specifically, each layer of composite material 4 has a length and width of 476mm 400mm 0.25mm, which includes 100 sheets of the same size curved composite sheet; platen 3 is made of smooth stainless steel and has a length and width of 625mm 450mm 1 mm. The number of compacts 5 is 16, and each compact 5 has a length, width and height of 50mm 80mm 50mm and a weight of 10kg, so as to apply a suitable pressure to the composite material therebelow.

When the composite material is in work, a press plate is placed on the support, then 100 bent sheets are placed on the press plate, a press plate is placed above the sheets, 100 sheets are placed above the second press plate, and the steps are repeated, so that the thickness of the composite material can not exceed 700mm at most. And finally, uniformly placing 16 pressing blocks on the uppermost pressing plate, placing the whole support on a storage plate of an oven by using a forklift, opening the oven, adjusting the temperature to 50 ℃, taking out the support after 10-12h, and aligning molecular chains of the uneven sheet to be rearranged under the action of long-time low temperature and load, so that the internal stress is reduced and the sheet becomes flat.
