Description

Technical Field

[0001] This application relates to the technical field of ceramicized silicone rubber composite tape production equipment, and in particular to a coating device for ceramicized silicone rubber composite tape production that facilitates film roll replacement. Background Technology

[0002] Ceramicized silicone rubber composite tape uses fiberglass fireproof cloth as the base material, with a ceramicized organosilicon coating on the surface and a high-adhesion adhesive film on the bottom. At room temperature, it not only has excellent elasticity and electrical properties, but also has excellent fire resistance. When ablated at high temperatures, it forms a hard ceramicized protective layer, which plays a role in fire prevention and fire resistance.

[0003] During the production process, after applying a high-adhesion adhesive, the surface needs to be coated. Existing coating equipment generally includes a conveyor frame, and the surface of the conveyor frame is equipped with a pressure roller mechanism and an unwinding mechanism. The unwinding mechanism is fixed on the conveyor frame. Since the unwinding mechanism is at least 1.5 meters wide, it is inconvenient to change the film roll.

[0004] Therefore, in order to improve the efficiency of film roll replacement, it is urgent to improve the existing film coating equipment. Utility Model Content

[0005] The purpose of this application is to provide a coating device for the production of ceramicized silicone rubber composite tape that facilitates the replacement of film rolls, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a coating device for the production of ceramicized silicone rubber composite tapes that facilitates film roll replacement, employing the following technical solution:

[0007] A coating device for producing ceramicized silicone rubber composite tape with easy film roll replacement includes a conveyor frame. The surface of the conveyor frame is provided with a pressure roller mechanism and an unwinding mechanism. The unwinding mechanism includes a support base, a base, a roller frame, an unwinding roller, and a tension shaft. The support base is fixed to the conveyor frame, and the base is slidably connected to the support base. Roller frames are symmetrically fixed to both sides of the base. The unwinding roller and the tension shaft are both mounted on the roller frames. An electromagnet assembly is fixed to one end of the support base, and an adsorption block is fixed to the end of the base corresponding to the electromagnet assembly. When the electromagnet assembly is energized, it can attract the adsorption block. A support frame is detachably fixed to the bottom of the base at the end furthest from the electromagnet assembly, and a caster wheel is installed at the bottom of the support frame.

[0008] Preferably, the roller frame includes a U-shaped frame and a shaft seat. The U-shaped frame is fixed on the base, and the shaft seat is disposed inside the U-shaped frame. The unwinding roller is rotatably connected inside the shaft seat. An installation block for placing the tensioning shaft is fixed inside the shaft seat. An installation groove is provided on the side wall of the installation block. The installation groove includes a vertical section and a horizontal section that are connected to each other.

[0009] By adopting the above technical solution, when replacing the membrane roll, it is only necessary to insert the expansion shaft loaded with the membrane roll from the horizontal section. The vertical section can provide guidance and limit for the expansion shaft, making the installation relatively simple.

[0010] The pressure roller mechanism includes a mounting frame, an upper pressure roller, a lower pressure roller, a transmission gear, a motor, and a reducer. The mounting frame is fixed on the frame of the conveyor frame. The upper and lower pressure rollers are rotatably mounted in the mounting frame, corresponding to each other. A driven gear is fixed to the end of each of the upper and lower pressure rollers. The transmission gear is rotatably connected to the mounting frame on one side and meshes with the driven gear. The reducer and motor are fixed to the side of the frame of the pressure roller mechanism. A drive gear is mounted on the output shaft of the reducer and meshes with the driven gear on the surface of the lower pressure roller.

[0011] Preferably, in order to facilitate the passage of the substrate, the surface of the support base is provided with a clearance groove.

[0012] Preferably, to ensure that the base does not shift when installing the film roll, the caster wheel has a self-locking function.

[0013] In summary, this application includes at least one of the following beneficial technical effects: the unwinding mechanism in the coating device for easy film roll replacement in the production of ceramicized silicone rubber composite tape can move left and right and be pulled out from the conveyor frame. After the unwinding mechanism is away from the conveyor frame, the side of the tension shaft has a large operating space. The operator can use a crane to put the new film roll into the mounting slot. After that, the base is pushed back to its original position, and the electromagnet assembly is energized to attract and fix the base. The whole replacement process is relatively simple, which greatly improves the effect of film roll replacement. The operator will not lean on the conveyor frame, which is safe and does not easily contaminate the substrate that has just been coated with high-adhesion adhesive. Attached Figure Description

[0019] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0020] This application discloses a coating device for producing ceramicized silicone rubber composite tapes that facilitates film roll replacement, referring to... Figures 1-4 The system includes a conveyor frame 1, on which a pressure roller mechanism 2 and an unwinding mechanism 3 are provided. The pressure roller mechanism 2 includes a mounting frame 21, an upper pressure roller 22, a lower pressure roller 23, a transmission gear 24, a motor 25, and a reducer 26. The mounting frame 21 is fixed on the frame of the conveyor frame 1. The upper pressure roller 22 and the lower pressure roller 23 are rotatably mounted in the mounting frame 21. The ends of the upper pressure roller 22 and the lower pressure roller 23 are each fixed with a driven gear 27. The transmission gear 24 is rotatably connected to the mounting frame 21 on one side and meshes with the driven gear 27. The reducer 26 and the motor 25 are fixed on the side of the frame of the pressure roller mechanism 2. A drive gear 28 is mounted on the output shaft of the reducer 26 and meshes with the driven gear 27 on the surface of the lower pressure roller 23.

[0021] The unwinding mechanism 3 includes a support base 31, a base 32, a roller frame 33, an unwinding roller 34, and a tension shaft 35. The support base 31 is fixed on the conveyor frame 1, and the base 32 is slidably connected to the support base 31. The roller frame 33 is symmetrically fixed on both sides of the base 32. The unwinding roller 34 and the tension shaft 35 are both set on the roller frame 33. The tension shaft 35 is used to fix the film roll. An electromagnet assembly 36 is fixed at one end of the support base 31, and an adsorption block 37 is fixed at the end of the base 32 corresponding to the end of the electromagnet assembly 36. When the electromagnet assembly 36 is energized, it can adsorb the adsorption block 37. A support frame 38 is detachably fixed at the bottom of the end of the base 32 away from the electromagnet assembly 36. A caster wheel 39 is installed at the bottom of the support frame 38. In order to ensure that the base 32 remains stable when changing the film roll, the caster wheel 39 has a self-locking function.

[0022] Reference Figure 4The roller frame 33 includes a U-shaped frame 331 and a bearing seat 332. The U-shaped frame 331 is fixed on the base 32, and the bearing seat 332 is disposed inside the U-shaped frame 331. The unwinding roller 34 is rotatably connected inside the bearing seat 332. The bearing seat 332 has a mounting block 4 for placing the tensioning shaft 35. The mounting block 4 has a mounting groove 41 on its side wall. The mounting groove 41 includes a vertical section 411 and a horizontal section 412 that are connected to each other. When changing the film roll, the tensioning shaft 35 loaded with the film roll can be inserted into the horizontal section 412. The vertical section 411 can provide guidance and limit for the tensioning shaft 35.

[0023] Reference Figure 1 To facilitate the passage of the substrate, a clearance groove 311 is provided on the surface of the support base 31.

[0024] The implementation principle of the coating device for producing ceramicized silicone rubber composite tape that facilitates film roll replacement in this application embodiment is as follows:

[0025] During use, the film is adhered to the substrate, and the pressure roller mechanism 2 presses the film and substrate together and conveys them forward. After the film roll is used up, the electromagnet assembly 36 is de-energized, and the side of the base 32 loses its attraction. The operator can easily pull the base 32 to one side, so that the expansion shaft 35 moves to the side of the conveyor frame 1. At this time, the side of the expansion shaft 35 has a large operating space, and the operator can use the overhead crane to put the new film roll into the mounting groove 41. After that, the base 32 is pushed back to its original position, and the electromagnet assembly 36 is energized to attract and fix the base 32. The whole replacement process is relatively simple, and the operator will not lean on the conveyor frame 1. It has high safety performance and is not easy to contaminate the substrate that has just been coated with high-adhesion adhesive.

[0026] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
