Description

A kind of antistatic diaphragm rolling device

Technical field

This utility model relates to a kind of plastic process equipment, particularly with the antistatic diaphragm rolling device producing plastic sheet.

Background technology

Plastic sheet is that one is widely used in the field plastics such as daily life, packaging, electron trade, industry, agricultural.Plastic sheet is divided into PP(polypropylene according to material difference), PVC(polrvinyl chloride), PS(polystyrene), PET(poly terephthalic acid class) etc..The preparation technology of plastic sheet includes extrusion, press polish, batches, section etc..The antistatic display screen protection film sheet that a kind of PP material is made, existing technique is to be pressed into certain thickness diaphragm by rolling device, then through masking liquid (painting liquid antistatic), dries, batches, cuts into slices and make.Wherein masking liquid operation is the performance in order to avoid affecting electronic original part in display screen transport and longer-term storage process because of electrostatic, surface-coated last layer liquid antistatic at diaphragm, liquid antistatic forms one layer of antistatic layer on the surface of antistatic diaphragm after drying, and antistatic layer can effectively eliminate or alleviate the adverse effect of electrostatic.The surface of common antistatic diaphragm is smooth flat, the smooth roll of rolling device suppress forming, there is the problem that 1, surface excessively bright and clean, make antistatic layer poor adhesive force on diaphragm, easily come off；2, antistatic diaphragm different station often in pile configuration state; smooth top layer makes to be susceptible to bonding between adjacent diaphragms; operator when taking diaphragm between diaphragm touching of the hands of phase mutual friction and diaphragm and operator often destroy antistatic layer, thus causing that antistatic diaphragm loses due effect.Additionally, the diaphragm of bonding causes trouble, the normal rhythm that impact produces to the operation of some operations mutually.The structure changing antistatic diaphragm is the effective way solving the problems referred to above, and the structure changing antistatic diaphragm then needs to improve the associated components of existing rolling device.

Utility model content

The purpose of this utility model is in that the drawback for prior art, it is provided that a kind of antistatic diaphragm rolling device for processing non-smooth surface diaphragm.

Problem described in the utility model realizes with following technical proposals:

A kind of antistatic diaphragm rolling device, including frame, frame arranges chill roll, the first pressure roller, the second pressure roller from top to bottom, described first pressure roller, the second pressure roller external cylindrical surface top layer gather depression or protruding, protruding height dimension or the depth dimensions of depression are 0.1-0.15 millimeter, and adjacent protrusion or the distance between adjacent recessed are 0.15-0.20 millimeter.

Above-mentioned antistatic diaphragm rolling device, the first pressure roller or the second pressure roller boss are round table-like distribution.

Above-mentioned antistatic diaphragm rolling device, the first pressure roller or the second pressure roller boss distribute as net shape.

Above-mentioned antistatic diaphragm rolling device, described frame front end is provided with diaphragm transition guide roller.

For the structure improvement of antistatic diaphragm, this utility model requires that the rolling device to being used for processing tradition plastic sheet has improved, the bright finish structure of the first pressure roller of conventional roll pressure device, the second pressure roller is improved to carving structure, namely the first pressure roller, the second pressure roller cylinder top layer processed densely covered raised or sunken by electric spark artistic carving, so, can suppress corresponding protruding and depression in pressing process on antistatic diaphragm top layer, this non-smooth surface antistatic diaphragm can effectively solve antistatic layer and come off problem.Additionally, adopt this utility model can also solve the adhesion problem between antistatic diaphragm, improve production efficiency 15-20%.

Detailed description of the invention

Referring to Fig. 1, Fig. 2, this utility model includes frame 1, and frame arranges chill roll the 2, first pressure roller the 3, second pressure roller 4 from top to bottom, and the outlet of the die head 5 of extruder is positioned between the first pressure roller and the second pressure roller, and frame front end is provided with diaphragm transition guide roller 6.Counter-rotation the first pressure roller, the second pressure roller are by compressing for antistatic diaphragm 7, and the cooled roller of antistatic diaphragm, diaphragm transition guide roller 6 enter masking liquid operation.First pressure roller of the present utility model, the second pressure roller external cylindrical surface top layer gather depression or protruding, the height dimension of boss or the depth dimensions of depression are 0.1-0.15 millimeter, and adjacent protrusion or the spacing between adjacent recessed position are 0.15-0.20 millimeter.

First pressure roller, the second pressure roller are hollow-core construction, the first pressure roller or the second pressure roller boss be round table-like distribution as in Figure 3-5.

Another embodiment of the present utility model, the boss of the first pressure roller or the second pressure roller distributes as net shape as shown in Figure 6, Figure 7.

First pressure roller, the raised or sunken of the second roller surface are processed by electric spark artistic carving, and the first pressure roller, the second pressure roller can adopt similar and different projection and depression distributed architecture.Adopting rolling device described in the utility model, it is possible to prepare surface with protruding and depression antistatic diaphragm, this shaggy antistatic diaphragm increases the adhesive force of antistatic layer, and mutually piles up and be not susceptible between the diaphragm put bond.
