Description

Technical Field

[0001] This utility model relates to the field of mica tape production technology, and in particular to a winding device for solvent-free mica tape lamination. Background Technology

[0002] Current mica tape production, especially in the production of three-layer composite mica tape materials, requires two adhesive bonding processes. This process typically uses solvent-based adhesives, which not only pose environmental pollution problems due to solvent evaporation during production but also limit the quality of the composite and production efficiency. With continuous technological advancements and increasing environmental awareness, the application of solvent-free adhesives in mica tape lamination processes is gradually becoming a trend. Solvent-free adhesives have significant advantages such as environmental friendliness, low volatility, and fast curing speed, effectively improving lamination quality and production efficiency while reducing environmental pollution during production. After passing through a solventless lamination device, mica paper forms a three-layer composite structure of film-mica paper-film and is output from the lamination device. The composite product is then recycled by a winding device. However, traditional winding devices for mica tape lamination are only designed for solvent-laminated mica tape and require additional drying structures to dry the adhesive on the laminated mica tape. In solventless lamination, the adhesion between the mica paper and film after the second lamination is insufficient, making it prone to displacement and misalignment during winding, affecting the lamination effect. Therefore, a winding device for solventless mica tape lamination is needed that can reinforce the mica tape after the second lamination without requiring complex structures such as drying structures, ensuring the winding effect of the mica tape after solventless lamination. Utility Model Content

[0003] The purpose of this invention is to provide a winding device for solventless mica tape lamination, which solves the problems of traditional winding devices having complex structures and lacking the function of reinforcing solventless mica tape.

[0004] The present invention provides the following technical solution: a winding device for solvent-free mica tape lamination, comprising a frame, a feeding mechanism, a reinforcing mechanism, and a winding mechanism mounted on the frame. The feeding mechanism includes an upper tensioning roller and a lower tensioning roller that press against the front side of the material, and a movable tensioning roller located between the upper tensioning roller and the lower tensioning roller and pressing against the back side of the material. The reinforcing mechanism includes a first pressing roller and a second pressing roller correspondingly arranged, and a pressing driver and a rotation driver fixed to the frame. The first pressing roller and the second pressing roller receive material output from the lower tensioning roller. The pressing driver drives the first pressing roller to move radially closer to the second pressing roller to press the material. The rotation driver drives the second pressing roller to rotate to maintain continuous material input. The winding mechanism includes a take-up roller and a take-up driver. The take-up driver drives the take-up roller to rotate to wind up the material output from the reinforcing mechanism.

[0005] As described above, in a winding device for solvent-free lamination of mica tape, the first clamping roller and the second clamping roller are arranged in parallel, and a reinforcing roller pressure zone is formed between the first clamping roller and the second clamping roller. The clamping drivers are arranged in pairs and are respectively connected to the two ends of the first clamping roller and the frame.

[0006] As described above, in a winding device for solventless lamination of mica tape, the output end of the clamping driver is extended and retracted along the height direction of the frame to drive the first clamping roller to move closer to or further away from the second clamping roller along the height direction of the frame, thereby reducing or increasing the passing height of the reinforcing roller pressure zone.

[0007] As described above, in a winding device for solvent-free lamination of mica tape, the rotary driver is fixed to one side of the frame, and a coaxial transmission wheel is fixed to one end of the second pressing roller. The output end of the rotary driver drives the rotation of the transmission wheel through belt drive, thereby driving the rotation of the second pressing roller and thus driving the material to continuously pass through the reinforcing roller pressing zone.

[0008] As described above, in a winding device for solventless lamination of mica tape, the diameter of the first pressing roller is larger than the diameters of the upper tensioning roller, the lower tensioning roller, and the movable tensioning roller, and the diameter of the second pressing roller is larger than the diameters of the upper tensioning roller, the lower tensioning roller, and the movable tensioning roller, respectively.

[0009] As described above, a winding device for solventless lamination of mica tape includes a feeding mechanism for receiving the composite material of film-mica paper-film after lamination. The material is sequentially wound around the upper tensioning roller, the movable tensioning roller, and the lower tensioning roller, and input into the space between the first pressing roller and the second pressing roller in a "Z"-shaped tensioned state.

[0010] As described above, a winding device for solventless lamination of mica tape includes a feeding mechanism that further includes a lifting driver for driving the movable straightening roller to move up and down radially. When the lifting driver drives the movable straightening roller to rise, it straightens the material wound between the upper straightening roller and the lower straightening roller. When the lifting driver drives the movable straightening roller to fall, it relaxes the material wound between the upper straightening roller and the lower straightening roller.

[0011] As described above, a winding device for solventless lamination of mica tape has a pair of disassembly ports on the frame, and the two ends of the winding roller are detachably connected to the pair of disassembly ports.

[0012] As described above, in a winding device for solvent-free lamination of mica tape, the winding driver is fixed to one side of the frame, and the output end of the winding driver drives the rotation of the winding roller through belt drive, so as to drive the winding roller to continuously wind up the material output between the first pressing roller and the second pressing roller.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This utility model discloses a winding device for solventless lamination of mica tape. The device comprises a feeding mechanism, a reinforcing mechanism, and a winding mechanism on a frame. The feeding mechanism uses an upper straight roller, a lower straight roller, and a movable straight roller to initially straighten the three-layer composite material of film-mica paper-film and then convey it to the reinforcing mechanism. The reinforcing mechanism uses a first pressure roller and a second pressure roller to apply relative reinforcing roller pressure to the front and back of the three-layer composite material, achieving a secondary lamination and reinforcement effect after the lamination process. Finally, the rotating take-up roller in the winding mechanism winds up the three-layer composite material, ensuring a good winding effect. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to the appendix Figure 1 To be continued Figure 3 This embodiment provides a winding device for solvent-free lamination of mica tape, including a frame 1, a feeding mechanism 2, a reinforcing mechanism 3, and a winding mechanism 4 mounted on the frame 1. The feeding mechanism 2 includes an upper tensioning roller 21 and a lower tensioning roller 22 that press against the front side of the material, and a movable tensioning roller 23 located between the upper tensioning roller 21 and the lower tensioning roller 22 and pressing against the back side of the material. The reinforcing mechanism 3 includes a first pressing roller 31 and a second pressing roller 32 that are correspondingly arranged, and a pressing driver 3 fixed to the frame 1. The material output from the lower straight roller 22 is received between the first pressing roller 31 and the second pressing roller 32 and the rotary driver 34. The pressing driver 33 is used to drive the first pressing roller 31 to approach the second pressing roller 32 radially to press the material. The rotary driver 34 is used to drive the second pressing roller 32 to rotate to maintain the continuous input of material. The winding mechanism 4 includes a take-up roller 41 and a take-up driver 42. The take-up driver 42 is used to drive the take-up roller 41 to rotate to wind up the material output from the reinforcing mechanism 3. The winding device for solventless mica tape lamination in this embodiment includes a feeding mechanism 2, a reinforcing mechanism 3, and a winding mechanism 4 on a frame 1. The feeding mechanism 2 uses an upper straight roller 21, a lower straight roller 22, and a movable straight roller 23 to initially straighten the three-layer composite material of film-mica paper-film and then convey it to the reinforcing mechanism 3. The reinforcing mechanism 3 uses a first pressure roller 31 and a second pressure roller 32 to apply relative reinforcing roller pressure to the front and back of the three-layer composite material, so that the composite material after the lamination process has a secondary lamination and reinforcement effect. Finally, the winding mechanism 4 uses a rotating take-up roller 41 to wind up the three-layer composite material, ensuring that the material has a good winding effect.

[0021] The first pressing roller 31 and the second pressing roller 32 are arranged in parallel, forming a reinforcing roller pressing zone 35 between them. Pressing actuators 33 are arranged in pairs and connected to both ends of the first pressing roller 31 and the frame 1, respectively. Furthermore, the output end of the pressing actuator 33 is extended and retracted along the height direction of the frame 1 to drive the first pressing roller 31 closer to or further away from the second pressing roller 32 along the height direction of the frame 1, thereby reducing or increasing the passage height of the reinforcing roller pressing zone 35. By adjusting the extension and retraction height of the pressing actuator 33, the height of the reinforcing roller pressing zone 35 can be flexibly adjusted according to the specific composite thickness of the material, giving the device a certain degree of versatility for materials of different thicknesses.

[0022] The rotary driver 34 is fixed to one side of the frame 1. One end of the second pressing roller 32 is fixed with a coaxially arranged transmission wheel 321. The output end of the rotary driver 34 drives the transmission wheel 321 to rotate through the belt drive, thereby driving the rotation of the second pressing roller 32, which in turn drives the material to continuously pass through the reinforced roller pressing area 35. At this time, the first pressing roller 31 rotates in the opposite direction to the second pressing roller 32 under the friction of the material, realizing the simultaneous rolling effect on the front and back sides of the material.

[0023] Preferably, the diameter of the first pressing roller 31 is larger than the diameter of the upper tensioning roller 21, the lower tensioning roller 22, and the movable tensioning roller 23, and the diameter of the second pressing roller 32 is larger than the diameter of the upper tensioning roller 21, the lower tensioning roller 22, and the movable tensioning roller 23, respectively. The large diameter of the first pressing roller 31 and the second pressing roller 32 is beneficial to the roll pressing reinforcement effect on the material.

[0024] The feeding mechanism 2 is used to receive the composite material of film-mica paper-film after lamination. The material is sequentially wrapped around the upper straight roller 21, the movable straight roller 23 and the lower straight roller 22, and fed into the first pressing roller 31 and the second pressing roller 32 in a "Z" shaped straight state. This can prevent the material from turning inward or shifting when it is fed into the reinforcement mechanism after lamination.

[0025] The feeding mechanism 2 also includes a lifting driver 24 for driving the movable tensioning roller 23 to rise and fall radially. When the lifting driver 24 drives the movable tensioning roller 23 to rise, it straightens the material wound between the upper tensioning roller 21 and the lower tensioning roller 22. When the lifting driver 24 drives the movable tensioning roller 23 to fall, it relaxes the material wound between the upper tensioning roller 21 and the lower tensioning roller 22. This arrangement is used to flexibly adjust the tension of the material on the winding device when the material is wound on the winding device, so that the material is input into the reinforcement mechanism 2 for roll pressing and reinforcement in the best tension state.

[0026] The frame 1 has a pair of disassembly ports 11. The two ends of the take-up roller 41 are detachably connected to the pair of disassembly ports 11. The take-up driver 42 is fixed to one side of the frame 1. The output end of the take-up driver 42 drives the rotation of the take-up roller 41 through belt drive, so as to drive the take-up roller 41 to continuously take up the material output between the first pressure roller 31 and the second pressure roller 32. The disassembly ports 11 facilitate the installation and disassembly of the take-up roller 41, so as to facilitate the unloading and transfer of composite materials.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
