The invention provides a production equipment with simple operation, improves the production efficiency of the membrane switch coating process, and greatly reduces the incidence of defective products in the film coating process.
     In order to overcome the lack of rapid change mechanism of the laminating machine in the original color coating production line, the laminating machine has the advantages of poor working efficiency, poor precision, slow response, and large labor intensity of manual alignment. The technical solution adopted by the present invention is one. The laminating machine is composed of an uncoiler, a looper and a press machine, and the uncoiler is fixed on the base of the looper, and the press machine is installed on the production line, and the laminating machine of this structure can be quickly changed, Continuous production, automatic centering, automatic flattening, and temperature adjustment function, greatly improve work efficiency and save production costs.

The laminating machine can be divided into two types: instant coating laminating machine and pre-coating laminating machine. It is a special equipment for paper and film. The instant coating laminating machine consists of three parts: sizing, drying and hot pressing. It has wide application range and stable and reliable processing performance. It is a widely used laminating equipment in China. Pre-coated laminating machine, without glue and dry parts, small size, low cost, flexible operation, not only suitable for laminating processing of large-volume printed materials, but also suitable for coating of small batches and scattered printed materials such as automated desktop office systems. Processing is very promising.
               The vibration of the laminator mechanism is one of the important factors affecting the accuracy of the film. With the rapid development of the printing and packaging industry at home and abroad, all kinds of printing equipment and post-press processing equipment have developed by leaps and bounds. In the post-press processing, vegetable greenhouse filming technology has been widely used.
              In the existing laminating equipment in China, the difficulty is difficult to improve, which is the main reason that restricts its development. In the post-press processing, the laminating technology is widely used, and the high-speed, high-precision laminating machine is urgently needed in the market. Based on the analysis of the test technology principle, based on the Dongpu signal test and analysis system software, a relatively complete vibration test program of the laminator was selected, and the vibration test of the main components of the laminator was carried out. The results show that the vibration at the wallboard is the largest, followed by the front gauge shaft, and the movement of the side gauge shaft is relatively stable and the vibration is minimal.

The laminator has high requirements for temperature control. If the temperature is too high, the heating time is too long, the film quality will drop, and there is no heating. If the drying temperature is too high, the surface of the adhesive is crusted, causing foaming of the film. Excessive thermal stress can also cause the film to lose its elasticity, resulting in reduced performance and tearing.
There are three methods of heat dissipation in physics: conduction, convection and radiation. The first two have been eliminated. It is only solved by thermal radiation. Radiation heat dissipation can be unaffected by the temperature of the medium around the object. As long as the temperature of the object exceeds zero, the object must go out. Radiant heat, but it is very small in terms of the amount of heat radiation of the object itself. It can't solve the problem of heat dissipation and cooling of the object. Only increase the amount of heat radiation of the object to reduce the temperature of the object, so that a layer of heat-dissipating paint is applied on the surface of the object. The heat-dissipating paint greatly enhances the amount of heat radiation of the object to reduce the temperature of the object.
The heat-dissipating coating enhances heat exchange in the form of infrared radiation, and the heat dissipation is not affected by the surrounding medium. The heat dissipation of the paint can be used in a vacuum environment. The ZS-411 radiation heat-dissipating paint improves the heat exchange and also has a good self. Clean, insulating, anti-corrosive, waterproof, acid and alkali resistant, easy to construct.

The pre-coating laminator is a special device that combines printed matter with pre-coated plastic. Compared with the coating type laminating machine, the biggest feature is that there is no coating and drying part, so the laminating machine has compact structure, small volume, low cost, simple operation and good product quality stability.
Pre-coated laminating machine consists of pre-coated plastic film unwinding, automatic print input, hot-pressing area compounding, automatic winding, four main parts, as well as mechanical transmission, pre-coated plastic film flattening, vertical and horizontal slitting, computer control system And other auxiliary devices.
1. The automatic conveying mechanism of the input part of the printed matter can ensure that the printed matter does not overlap during the transmission and enters the composite part equidistantly. Generally, the pneumatic or frictional method is used for control, and the conveying is accurate and high precision. When the composite printing medium is small, the same can be used. Meet the above requirements.
2. The composite part comprises a composite roll set and a calender roll set. The composite roller set consists of a silicone heated pressure roller pressure roller. The hot pressure roller is a hollow roller with a heating device inside, the surface is forged with hard chrome, and is polished and refined; the temperature of the hot roller is tracked by the sensor and the computer is corrected at any time; the adjustment of the composite pressure is performed by an eccentric cam mechanism, pressure Can be adjusted steplessly. The calender roll set is basically the same as the composite roll set, that is, the chrome plated pressure roll is composed of a silicone pressure roll, but there is no heating device. The main function of the calender roll group is: after the pre-coated plastic film is combined with the printed matter by the composite roll set, the surface brightness is not high, and then the second step of the calender roll group, the surface brightness and the bond strength are greatly improved.
3. Transmission system The transmission system is driven by a computer-controlled high-power motor. After the first-stage gear is decelerated, it is driven by a three-stage chain to drive the movement of the paper feeding mechanism and the rotation of the composite part and the silicone pressure roller of the calendering mechanism. The pressure roller set maintains the proper working pressure under the pressure of the stepless adjustment.
4. Computer Control System The computer control system uses a microprocessor. The hardware configuration consists of a motherboard, a digital keypad, an optical isolation board, a power board, and a stepper motor power driver board.

The laminator is a specialized device dedicated to paper and film. Laminating machine It is divided into two categories: “coating type laminating machine” and “pre-coating laminating machine”. For these two classifications, its function and application object are also different.
      Instant coating laminator
      The operation of the coating type laminating machine includes three parts of gluing, drying and hot pressing, and the operation is relatively high. The advantage is that the quality of the finished product is reliable. It has a fatal disadvantage that the oily rubber will produce gas which affects human health, so Such technologies have been completely banned in developed countries such as Europe and the United States. Water-based adhesives are more environmentally friendly than oil and have relatively high oil costs.
      Pre-coated laminating machine
      The pre-coating laminating machine is formed in one time. The consumables used have been coated with glue. When the film is coated, the glue is melted by heating, and then the film is bonded to the printed matter by pressure. This kind of laminating equipment is cheap, easy to operate, and does not generate harmful gases during operation. It is a trend of film development. In today's society where environmental protection is increasingly concerned, it is believed that this technology will one day replace the pre-coated film. The main coating technology in the domestic printing industry. The disadvantage is that this technology is not very mature in China, and there are still some problems to be solved, such as: single-sided film curling (has a single-sided anti-curl machine, but the price is higher), the print with silicone oil is difficult to cover Membrane and the like. Widely used in short-run printing, digital fast printing industry.
