Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a coating and drying equipment for electromagnetic heating release films. Background Art

[0002] Since the transfer coating process can effectively prevent the substrate of the film or tape from being subjected to high temperature, most products such as films or tapes with adhesive backing are produced using the transfer coating process. The coating and drying equipment used in the transfer coating process generally uses electric heating rods or electric heating wires to convert electrical energy into thermal energy of the electric heating rods or electric heating wires, and the thermal energy of the electric heating rods or electric heating wires is transferred to the air. The fan then blows the heated air to the release film in the coating machine and the liquid adhesive layer coated on the release film. The dried adhesive layer and the release film are compounded with the substrate of the film or tape, thereby transferring the adhesive layer to the surface of the substrate, completing the transfer coating process and the final product.

[0003] At present, the existing technology still has the following areas for improvement: the existing liquid glue layer is very likely to form a crust on the surface in the electric heating drying equipment, which makes it difficult for the solvent inside the liquid glue layer to evaporate and forms bubbles. Conventional electric heating drying equipment uses hot air to heat from the surface to the inside, which easily leads to the problem of crusting and bubbles. In the electric heating drying method, the flowing air needs to be heated to transfer heat. When removing the solvent, it will also take away a lot of heat, which consumes a lot of energy. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides an electromagnetic heating release film coating and drying device, which can solve the problem that the existing transfer coating electric heating and drying equipment is prone to produce adhesive layer crusting and bubbles.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A coating and drying device for an electromagnetic heating release film, comprising a bottom plate, a left support roller, a right support roller, a non-magnetic isolation layer and an electromagnetic wave generating coil assembly, wherein the electromagnetic wave generating coil assembly is fixedly connected to the bottom plate, and a left isolation layer bracket and a right isolation layer bracket are fixedly arranged on the bottom plate, wherein the left isolation layer bracket and the right isolation layer bracket are respectively located on the left and right sides of the electromagnetic wave generating coil assembly, and both ends of one side of the non-magnetic isolation layer are respectively located on the left isolation layer bracket and the right isolation layer bracket;

[0007] Two left support frames and two right support frames are fixedly arranged on the bottom plate, the left support roller is rotatably connected to the two left support frames, the right support roller is rotatably connected to the two right support frames, the left support roller is located on the left side of the left isolation layer support, and the right support roller is located on the right side of the right isolation layer support;

[0008] The left and right infrared temperature sensors are fixedly arranged on the bottom plate. The left infrared temperature sensor is located on the left side of the left support frame, and the right infrared temperature sensor is located on the right side of the support frame.

[0009] Furthermore, both of the left support frames are integrally formed with the bottom plate, both of the right support frames are integrally formed with the bottom plate, the left isolation layer support is integrally formed with the bottom plate, and the right isolation layer support is integrally formed with the bottom plate.

[0010] Furthermore, the non-magnetic isolation layer, the left support roller and the right support roller are all made of aluminum alloy, and anti-sticking coatings are provided on both the left support roller and the right support roller.

[0011] Furthermore, the electromagnetic wave generating coil assembly is composed of four small circular electromagnetic wave generating coils.

[0012] Furthermore, the four small circular electromagnetic wave generating coils are connected in series.

[0013] Furthermore, the electromagnetic wave generating coil assembly is a large circular electromagnetic wave generating coil.

[0014] Furthermore, the electromagnetic wave generating coil assembly is composed of four small rectangular electromagnetic wave generating coils, and the four small rectangular electromagnetic wave generating coils are connected in series.

[0015] The beneficial effects of the present utility model are as follows:

[0016] (1) By providing the electromagnetic wave generating coil assembly, the technical effect that can be achieved is that an electromagnetic wave generating coil assembly is fixedly connected to the bottom plate, and the electromagnetic wave generating coil assemblies are connected in series. If one of the electromagnetic wave generating coils is damaged, all the electromagnetic wave generating coils will stop working, and it is very easy to feedback the problems of the equipment through temperature for easy maintenance. In the electromagnetic heating mode, the flowing air generated by the fan only serves to carry away the solvent vapor and does not need to be heated, so less heat is carried away during discharge, which is more energy-saving.

[0017] (2) By providing the left and right infrared temperature sensors, the technical effect that can be achieved is that the left and right infrared temperature sensors are fixedly arranged on the bottom plate. The left infrared temperature sensor is located on the left side of the left support frame, and the right infrared temperature sensor is located on the right side of the support frame. The left and right infrared temperature sensors respectively detect the bottom temperatures before and after the electromagnetic heating release film enters, preventing the temperature from being too high or too low. Both the left and right infrared temperature sensors are non-contact type, and can test the temperature faster and more sensitively.

[0018] (3) By setting up a non-magnetic isolation layer, the achievable technical effect is that both ends of one side of the non-magnetic isolation layer are respectively located on the left isolation layer bracket and the right isolation layer bracket. The non-magnetic isolation layer can prevent the accidentally overflowed liquid glue layer from dripping onto the electromagnetic wave generating coil assembly and contaminating the coil. Moreover, due to the non-magnetic property of the non-magnetic isolation layer, electromagnetic waves can pass through smoothly and reach the electromagnetic heating release film. The alternating magnetic field with a frequency of 20 kHz to 25 kHz is consistent with the frequency of household induction cookers, meeting the requirements of relevant standards and regulations. At the same time, the basic supply chain of various accessories can be shared with the induction cooker industry, making the production and maintenance of the supporting coating and drying equipment have stable and relatively low comprehensive costs.
