The currently widely used method is to use an artificial primer treatment agent. After preliminary drying, the double-sided PET film is coated. After the lamination is completed, the PET is laminated to the silicone rubber surface by hot pressing or cold bonding. Then, the required hollow mouth frame is punched out by a punching device. The whole process is scattered, and the primer is easily unevenly coated, resulting in large waste. The flatness of the PET film lamination is difficult to ensure, and the punching into the mouth frame is seriously wasteful. The whole process has low labor efficiency, difficult to control links, and is also easy to affect product quality.

DETAILED DESCRIPTION

[0029] The purpose of the present invention is further described in detail below with reference to the accompanying drawings and specific examples. The examples cannot be described one by one here, but the implementation methods of the present invention are not therefore limited to the following examples.

[0030] like Figure 1As shown, a frame-type silicone rubber composite PET production line includes an unwinding device 1, a punching device 2, a glue-dispensing calendering device 3, an adjustable constant temperature tunnel furnace 4, a traction device 5, a step-control optical fiber device 6, a punching and cutting frame device 7 and a material receiving device 8 connected in sequence. The unwinding device 1 includes an expansion shaft and a tension control structure, which can fix the PET film roll and control the tension of the PET film, so as to pre-lay a layer of PET film on the lower surface of the product. The punching device 2 mainly punches positioning holes and air holes in the PET film to prevent the PET film with liquid silicone rubber from expanding due to the wrapped air during the heating and curing process, resulting in bulging and deformation of the mouth-shaped frame product. The main function of the glue-dispensing calendering device 3 is to add liquid silicone rubber to the PET film according to the specified position, and then calender the glue-dispensed PET film to a certain thickness. The adjustable constant temperature tunnel furnace 4 can set different temperatures and speeds to ensure that the liquid silicone rubber is at a certain required baking temperature and baking time in the tunnel furnace box 42, so that the liquid silicone rubber can be converted into solid silicone rubber. The traction device 5 provides power for the PET film, and pulls the PET film with solid silicone rubber out of the adjustable constant temperature tunnel furnace 4. At the same time, it has a deviation correction function to ensure that the PET film does not deviate during the traction process. The main function of the step-control optical fiber device 6 is to ensure that the semi-finished product is delivered to the punching and framing device 7 at a set distance, which can avoid waste of materials. The function of the punching and framing device 7 is to punch the PET film with solid silicone rubber into a set shape, and the knife die can be changed as needed. The material receiving device 8 is used to transport the punched PET film with solid silicone rubber to the next process, so that the operator can check the product on the transmission belt 41 and take out the product packaging. In addition, the winding mechanism 81 is used to recycle the remaining PET film and excess solid silicone rubber tailings.

[0031] Workflow: The unwinding device 1 introduces the bottom PET film into the punching device 2, and the punching device 2 punches positioning holes and air holes in the bottom PET film. The punched bottom PET film is pulled into the glue dispensing and calendering device 3, and the glue dispensing mechanism 31 adds liquid silicone rubber to the upper surface of the punched bottom PET film. Then the unwinding device 1 adds the upper PET film on the upper surface of the liquid silicone rubber. After the PET film with liquid silicone rubber is pressed to a certain thickness by the calendering roller 33, it is sent to the adjustable constant temperature tunnel furnace 4 for baking at a set time and a set temperature to obtain a PET film with solid silicone rubber. The PET film with solid silicone rubber is pulled out of the adjustable constant temperature tunnel furnace 4 by the pulling device 5. The step-control optical fiber device 6 controls the speed of the solid silicone rubber and sends it into the punching and framing device 7 according to a certain amount. The punching and framing device 7 punches a certain shape on the PET film with solid silicone rubber. The receiving device 8 transfers the frame-shaped solid silicone rubber PET film to the next process, and rolls up the remaining PET film and solid silicone rubber tailings for recycling.

The purpose of punching is to facilitate the subsequent positioning of the film and facilitate ventilation during the calendering process, so as to prevent the air wrapped by the upper PET film and the lower PET film from expanding during the heating and curing process, causing the product to bulge or deform. The function of the material break sensor 21 is to alarm and stop the machine when the PET film is missing. In order to ensure the consistency of the position of the punching hole on the film, the width adjustment device uses a manual adjustment bolt method to adjust the width of the puncher 22.
