Description

Technical Field

[0001] The present invention relates to the technical field of processing degradable electrical tapes, and specifically relates to a processing device and production process for degradable electrical tapes. Background Art

[0002] Electrical tapes are widely used in many fields such as electric power, electronics, communication, and construction. Traditional electrical tapes mostly use non-degradable materials such as polyvinyl chloride (PVC) as the base material, and the adhesives often contain a large amount of chemical additives. It is difficult to naturally degrade after use, causing long-term pollution to the environment. With the enhancement of environmental awareness and the increasing strictness of environmental protection regulations, the development of degradable electrical tapes has become an inevitable trend in the industry.

[0003] Degradable electrical tapes need to use degradable materials to make the base tape, such as commonly used polylactic acid (PLA) and polyhydroxyalkanoates (PHA), and coat degradable adhesives. However, compared with traditional plastic base tapes, materials such as PLA and PHA have poor heat resistance. If the traditional high-temperature coating process is used, the base tape is prone to deformation, softening, or even degradation; without using high-temperature coating, problems such as adhesive layer peeling off and low peel strength are likely to occur.

[0004] When ensuring good bonding between the base tape and the adhesive and overcoming the problem of poor thermal stability of the base tape material, it is usually necessary to use hot air baking to dry the adhesive. However, the common hot air baking method has obvious drawbacks. Not only does it require a long baking device to be set along the length of the electrical tape, occupying a large space, which in turn leads to poor energy conservation; but also hot air baking easily promotes the release of volatile substances from the base tape and adhesive materials, forming waste gas, and the environmental protection performance is not good.

[0005] Therefore, how to optimize the coating process, while ensuring uniform coating and firm adhesion of the adhesive layer, and improving the energy conservation and environmental protection level in the processing of degradable electrical tapes has become a key problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0015] Second part The production process of producing degradable electrical insulating tape based on the processing device described in the first part includes the following steps: S1. Preparation work before production; S2. Baseband conveying; S3. Surface treatment; S31. When the baseband enters the processing area of the surface treatment component, start the surface treatment component; S32. Set the RF power of the surface treatment component to 100 - 300 W, and act on the surface of the baseband through plasma to improve its surface energy and activity; S4. Glue spraying treatment; S41. When the baseband enters the processing area of the glue spraying component, turn on the glue spraying component and adjust the glue spraying pressure to 0.2 - 0.5 MPa; S42.

The waste gas treatment component further purifies the waste gas and then discharges it; S54. After the baseband after lamination and drying is output from the conveying component again, the production of the degradable electrical insulating tape is completed.

[0017] The beneficial effects achieved: This application uses a degradable baseband and adhesive, which conforms to the environmental protection concept, can be naturally degraded after use, and reduces the long-term pollution to the environment. And through the negative pressure pump and the waste gas treatment component, the waste gas generated during the production process is effectively collected and treated, reducing the pollution to the atmospheric environment and meeting the requirements of environmental protection regulations. The drying component is set on the laminating component, which can reasonably utilize space and energy. Therefore, by combining drying, lamination and waste gas treatment, it is possible to ensure uniform glue coating and firm adhesion of the glue layer while improving the energy conservation and environmental protection level of the processing process of the degradable electrical insulating tape.

[0029] The embodiments of the present application disclose a processing device and a production process for a degradable electrical tape.

[0030] Embodiment 1 Please refer to Figures 1 to 7 , in an embodiment of the present application, a processing device for a degradable electrical tape includes a frame 100. A conveying assembly 200 for conveying a base tape 900 is installed on the frame 100. Along the conveying direction of the conveying assembly 200 on the frame 100, a surface treatment assembly 300, a glue spraying assembly 400, and a pressing assembly 500 are sequentially arranged; a protective cover 101 is fixedly installed outside the glue spraying assembly 400 and the pressing assembly 500 on the frame 100. A drying assembly 600 is provided on the pressing assembly 500; a negative pressure box 102 is hermetically and fixedly connected to the top of the protective cover 101. One end of the negative pressure box 102 away from the protective cover 101 is hermetically connected to a negative pressure pump 103. The negative pressure pump 103 is fixedly installed on the frame 100. The pressing assembly 500 is hermetically connected in series between the negative pressure pump 103 and the negative pressure box 102. One end of the negative pressure pump 103 away from the pressing assembly 500 is hermetically connected to an exhaust gas treatment assembly 700.

[0031] The implementation principle of a processing device and a production process for a degradable electrical tape in the embodiments of the present application is as follows: First, the transport component 200 is used to drive the degradable base tape 900 to be transported on the rack 100, so that it passes through the surface treatment component 300, the glue spraying component 400, and the pressing component 500 in sequence. When the base tape 900 reaches the surface treatment component 300, the surface treatment component 300 processes the surface of the base tape 900 to improve the surface energy and activity of the base tape 900 and enhance its bonding performance with the adhesive. The surface-treated base tape 900 enters the glue spraying component 400, which evenly sprays the degradable adhesive on the surface of the base tape 900. The glue-sprayed base tape 900 enters the pressing component 500, which applies a certain pressure to it so that the adhesive and the base tape 900 are fully attached. At the same time, the drying component 600 dries it to solidify the adhesive. During the glue spraying and pressing process, waste gas will be generated. The protective cover 101 collects the waste gas, and the negative pressure pump 103 extracts the waste gas through the negative pressure box 102. After passing through the pressing assembly 500, the waste gas is sent to the waste gas treatment assembly 700 for purification.

[0032] Please refer to Figures 1 to 7 In one embodiment of the present application, the transmission assembly 200 includes a fixed seat 201 fixedly mounted on one end of a frame 100, a driving shaft 202 is rotatably connected to the fixed seat 201, a driving roller 203 is fixedly connected to the driving shaft 202, a first driving member 204 is fixedly mounted on the frame 100 and is transmission-connected to the driving roller 203, an adjusting seat 205 is fixedly mounted on one end of the frame 100 away from the fixed seat 201, a mounting shaft 206 is slidably connected to the adjusting seat 205, a driven roller 207 is rotatably connected to the mounting shaft 206, and a conveyor belt 208 is transmission-connected between the driven roller 207 and the driving roller 203.

[0033] During operation, the first driving member 204 is started and outputs power to drive the driving shaft 202 to rotate. Since the driving shaft 202 is fixedly connected to the driving roller 203, the driving roller 203 rotates synchronously therewith. The driving roller 203 drives the conveyor belt 208 to run through friction, and the conveyor belt 208 drives the driven roller 207 to rotate. The driven roller 207 is installed on the mounting shaft 206, and the mounting shaft 206 can slide on the adjustment seat 205. This design can flexibly adjust the tension of the conveyor belt 208 to ensure that the base belt 900 can be stably transmitted under different working conditions. The base belt 900 is placed on the conveyor belt 208. As the conveyor belt 208 runs, the base belt 900 is smoothly transmitted from one end of the frame 100 to the other end, and passes through the subsequent processing components such as the surface treatment component 300, the spraying component 400, and the pressing component 500 in sequence.

[0034] Please refer to Figures 1 to 7, in an embodiment of the present application, a sliding groove 209 is provided on the adjusting seat 205 corresponding to the mounting shaft 206. A pull rod 210 passing through the sliding groove 209 is rotatably connected to the adjusting seat 205, and the pull rod 210 is threadedly connected to the mounting shaft 206.

[0035] During the working process, the position adjustment of the mounting shaft 206 on the adjusting seat 205 can be realized by rotating the pull rod 210. When the pull rod 210 is rotated, since the pull rod 210 is threadedly connected to the mounting shaft 206 and the pull rod 210 passes through the sliding groove 209 on the adjusting seat 205 and can rotate therein, according to the principle of screw drive, the rotational motion of the pull rod 210 is converted into a linear movement of the mounting shaft 206 along the direction of the sliding groove 209. The mounting shaft 206 drives the driven roller 207 to move, thereby changing the relative position between the driven roller 207 and the driving roller 203, and realizing the precise adjustment of the tension of the conveyor belt 208. During the adjustment process, the sliding groove 209 provides a guiding function for the movement of the mounting shaft 206 to ensure the accuracy of its movement direction.

[0036] Please refer to Figures 1 to 7 , in an embodiment of the present application, the first driving member 204 includes a first motor 2041. The first motor 2041 is fixedly installed on the frame 100 through a motor mounting bracket 2045. A first driving pulley 2042 is fixedly installed on the output shaft of the first motor 2041. A first driven pulley 2043 is fixedly installed on the driving shaft 202 corresponding to the first driving pulley 2042. A first transmission belt 2044 is connected between the first driven pulley 2043 and the first driving pulley 2042.

[0037] During the working process, the first driving member 204 provides power for the driving shaft 202 by means of belt drive. When the first motor 2041 is started, the motor output shaft drives the first driving pulley 2042 fixed thereon to rotate. Since the first driving pulley 2042 and the first driven pulley 2043 are connected by the first transmission belt 2044, under the action of friction, the first transmission belt 2044 drives the first driven pulley 2043 to rotate synchronously. And the first driven pulley 2043 is fixedly installed on the driving shaft 202, so the driving shaft 202 rotates accordingly, and then drives the driving roller 203 installed on the driving shaft 202 to rotate. The driving roller 203 drives the conveyor belt 208 to run, realizing the conveyance of the base belt 900. In this process, the high-speed rotational motion of the motor is converted into a suitable rotational speed of the driving shaft 202 through the belt drive system to meet the requirements of the conveyance speed of the base belt 900.

[0038] Please refer to Figures 1 to 7, in an implementation manner of the present application, the surface treatment assembly 300 includes a first mounting seat 301. The first mounting seat 301 is fixedly installed on the frame 100 at a position close to the input end of the conveying assembly 200. A plasma spray head 302 is fixedly installed on the first mounting seat 301, and the plasma spray head 302 is connected to a plasma generator.

[0039] During the working process, the working core of the surface treatment assembly 300 is to modify the surface of the baseband 900 by using plasma. The plasma generator generates plasma, and these plasmas are rich in active particles such as high-energy ions, electrons, and free radicals. The plasma is transported to the plasma spray head 302 through a pipeline. When the baseband 900 is conveyed by the conveying assembly 200 to the lower part of the plasma spray head 302, the plasma spray head 302 sprays the plasma onto the surface of the baseband 900. The active particles in the plasma collide with the molecules on the surface of the baseband 900, causing the molecular chains to break, generating new free radicals and functional groups, thereby changing the chemical properties and physical structure of the surface of the baseband 900 and improving its surface energy and surface activity.

[0040] Please refer to Figures 1 to 7 , in an implementation manner of the present application, the glue spraying assembly 400 includes a glue input pipe 401. The glue input pipe 401 is rotatably connected to the frame 100 at a position close to the output end of the surface treatment assembly 300. One end of the glue input pipe 401 passing through the protective cover 101 is fixedly installed with a glue spraying pipe 402. A number of glue spraying nozzles 403 arranged in a linear array and densely distributed are installed on the glue spraying pipe 402 corresponding to the baseband 900 on the conveying assembly 200. The glue spraying nozzles 403 are hermetically connected to the glue spraying pipe 402. A turbine 404 is fixedly installed at one end of the glue input pipe 401 located outside the protective cover 101. A worm 405 is rotatably connected to the frame 100 corresponding to the turbine 404. The worm 405 is in transmission connection with the turbine 404, and a handwheel 406 is fixedly connected to the worm 405.

[0041] When the glue spraying assembly 400 works, by manually rotating the handwheel 406, the worm 405 fixedly connected thereto is driven to rotate. Since the worm 405 is in transmission connection with the turbine 404, the rotation of the worm 405 drives the turbine 404 to rotate. The turbine 404 is fixed on the glue input pipe 401, so the glue input pipe 401 rotates around its rotation connection point with the frame 100, and further drives the glue spraying pipe 402 installed at the other end of the glue input pipe 401 to rotate. The positions of the glue spraying nozzles 403 arranged in a linear array on the glue spraying pipe 402 also change accordingly, and the angle between the glue spraying nozzles 403 and the baseband 900 conveyed on the conveying assembly 200 can be adjusted to ensure that the glue spraying nozzles 403 can adapt to basebands 900 of different widths. At the same time, the degradable adhesive flows into the glue spraying pipe 402 through the glue input pipe 401 and is evenly sprayed onto the surface of the baseband 900 through the glue spraying nozzles 403 to complete the glue spraying operation.

[0042] Please refer to Figures 1 to 7 In one embodiment of the present application, a guide rod 407 is fixedly connected to the inside of the glue spray tube 402, and the guide rod 407 is arranged in a conical shape. The closer the guide rod 407 is to the glue input tube 401, the larger the cross-sectional diameter is, and the farther the guide rod 407 is from the glue input tube 401, the smaller the cross-sectional diameter is.

[0043] During operation, when the degradable adhesive flows into the glue spraying tube 402 through the glue inlet pipe 401, the glue spraying tube 402 is fixedly connected with a conical guide rod 407, and the cross-sectional diameter of the guide rod 407 is the largest near the glue inlet pipe 401, and the cross-sectional diameter is the smallest away from the glue inlet pipe 401. During the flow process, the adhesive will flow along the conical surface of the guide rod 407. As the diameter of the guide rod 407 gradually decreases, the cross-sectional area of ​​the channel where the adhesive flows also gradually decreases. According to the principles of fluid mechanics, when the fluid flows in a channel with a smaller cross-sectional area, the flow rate will increase and the pressure will decrease. In this way, the adhesive will be more evenly distributed on the entire cross-section of the glue spraying tube 402, and will flow to each glue nozzle 403 at a relatively uniform flow rate, and finally be evenly sprayed from the glue nozzle 403 onto the surface of the base tape 900.

[0044] Please refer to Figures 1 to 7 In one embodiment of the present application, the pressing assembly 500 includes a mounting frame 501, which is fixedly mounted on the frame 100. The center of the mounting frame 501 is rotatably connected to a center roller 502. The mounting frame 501 is located on the outer side of the center roller 502 and is rotatably connected to a first intermediate roller 503, a second intermediate roller 504, a third intermediate roller 505, and a fourth intermediate roller 506. The mounting frame 501 is located on the outer side of the first intermediate roller 503, the second intermediate roller 504, the third intermediate roller 505, and the fourth intermediate roller 506 and is rotatably connected to a first edge roller 507, a second edge roller 508, and a second edge roller 509. The roller 508, the third edge roller 509, the fourth edge roller 510, the first edge roller 507, the second edge roller 508, the third edge roller 509, and the fourth edge roller 510 are provided with a rubber-sparse mesh belt 511, and the rubber-sparse mesh belt 511 is wound around the third intermediate roller 505, the fourth intermediate roller 506, the center roller 502, the first intermediate roller 503, and the second intermediate roller 504 in sequence on the side close to the conveying assembly 200; the center roller 502 is transmission-connected with a second driving member 800, and the second driving member 800 is transmission-connected with the second intermediate roller 504 and the third intermediate roller 505.

[0045] During operation, the operation of the pressing assembly 500 depends on the coordinated rotation of each roller and the cooperation of the adhesive-sparse mesh belt 511. After the second driving member 800 is started, it drives the central roller 502 to rotate. Since the second driving member 800 is also in transmission connection with the second intermediate roller 504 and the third intermediate roller 505, these two rollers will also rotate accordingly.

[0046] The rotation of the center roller 502, the second intermediate roller 504 and the third intermediate roller 505 drives the first intermediate roller 503, the fourth intermediate roller 506, the first edge roller 507, the second edge roller 508, the third edge roller 509 and the fourth edge roller 510 to rotate together through the sparse rubber mesh belt 511. The side of the sparse rubber mesh belt 511 close to the transmission component 200 is sequentially wound around the third intermediate roller 505, the fourth intermediate roller 506, the center roller 502, the first intermediate roller 503 and the second intermediate roller 504 to form a continuous transmission and pressing structure.

[0047] like Figure 3 As shown, when the glue-sprayed base belt 900 is conveyed to the pressing assembly 500 along with the conveying assembly 200, the glue-sparse mesh belt 511 leaves the conveying assembly 200 and adheres to the base belt 900, and the base belt 900 is driven to the third intermediate roller 505, the fourth intermediate roller 506, the center roller 502, the first intermediate roller 503, and the second intermediate roller 504 in sequence. When the base belt 900 follows the glue-sparse mesh belt 511 to run to the second edge roller 508, the base belt 900 is separated from the glue-sparse mesh belt 511 and is again conveyed from the conveying assembly 200. During the operation of the adhesive mesh belt 511 and the base belt 900, the base belt 900 and the adhesive are tightly pressed together by utilizing the pressure applied by the adhesive mesh belt 511 and the third intermediate roller 505, the fourth intermediate roller 506, the center roller 502, the first intermediate roller 503, and the second intermediate roller 504, so that the adhesive can better penetrate and adhere to the base belt 900. At the same time, the mesh structure of the adhesive mesh belt 511 can effectively bake out the moisture in the adhesive solution, thereby ensuring the uniformity of the adhesive layer.

[0048] Please refer to Figures 1 to 7 In one embodiment of the present application, the glue-repelling mesh belt 511 is made of polytetrafluoroethylene (PTFE) material. PTFE has excellent chemical stability, corrosion resistance and low friction coefficient, is not easily adhered by glue, can effectively realize the glue-repelling function, and is resistant to high temperature and aging. During installation, ensure that the tension of the mesh belt is moderate to ensure that it can operate stably during operation without slipping or excessive relaxation, thereby achieving effective drainage and uniform distribution of the glue, while avoiding a large amount of residue and accumulation of the glue during the rolling process.

[0049] It can be understood that in other embodiments of the present application, the glue-repellent mesh belt 511 can also be made of silicone rubber. Silicone rubber has good elasticity, high and low temperature resistance, and chemical stability. Its surface energy is relatively low, and the glue solution is not easily attached. At the same time, it has good flexibility and can adapt to the shapes and movement requirements of different rolling components.

[0050] Please refer to Figures 1 to 7 , in an embodiment of the present application, the drying assembly 600 includes an electric heating wire 601, which is fixedly installed inside the central roller 502. The central roller 502 is made of a heat-conducting material. A first heat-insulating pipe 602 is fixedly and hermetically connected to the negative pressure box 102. The end of the first heat-insulating pipe 602 away from the negative pressure box 102 is rotatably and hermetically connected to the second intermediate roller 504. A first connecting pipe 603 is hermetically and rotatably connected between the first intermediate roller 503 and the second intermediate roller 504. A second connecting pipe 604 is hermetically and rotatably connected between the first intermediate roller 503 and the fourth intermediate roller 506. A third connecting pipe 605 is hermetically and rotatably connected between the third intermediate roller 505 and the fourth intermediate roller 506. A second heat-insulating pipe 606 is hermetically and rotatably connected to the third intermediate roller 505, and the second heat-insulating pipe 606 is hermetically connected to the negative pressure pump 103.

[0051] The electric heating wire 601 is installed inside the central roller 502. After being energized, the electric heating wire 601 generates heat. Since the central roller 502 is made of a heat-conducting material, the heat can be quickly transferred to the surface of the central roller 502. When the base belt 900 that has undergone glue spraying and preliminary pressing contacts the central roller 502, the heat on the surface of the central roller 502 will be conducted to the base belt 900 and the adhesive thereon, accelerating the volatilization of the solvent in the adhesive and achieving preliminary drying.

[0052] After the negative pressure pump 103 is started, a negative pressure environment is formed in the negative pressure box 102. Air enters the inside of the protective cover 101 from the outside in sequence and passes through the negative pressure box 102, the first heat-insulating pipe 602, the second intermediate roller 504, the first connecting pipe 603, the first intermediate roller 503, the second connecting pipe 604, the fourth intermediate roller 506, the third connecting pipe 605, and the third intermediate roller 505, and finally enters the second heat-insulating pipe 606. During this process, the air flows through the inside of each roller, taking away the solvent vapor volatilized from the base belt 900 and the adhesive. At the same time, it will also take away the heat inside the protective cover 101. When the hot air flows inside the roller, it will transfer the heat to the roller, thereby further promoting the drying of the base belt 900 and the adhesive. Moreover, the negative pressure ventilation can also timely discharge the waste gas generated during the drying process and purify it through the waste gas treatment assembly 700.

[0053] Please refer to Figures 1 to 7, in an embodiment of the present application, the second driving member 800 includes a second motor 801. The second motor 801 is fixedly installed on the frame 100. A second driving pulley 802 is fixedly installed on the output shaft of the second motor 801. A second driven pulley 803 is fixedly connected to the central roller 502. A second transmission belt 804 is drivingly connected between the second driving pulley 802 and the second driven pulley 803. A third driving pulley 805 is fixedly connected to the central roller 502. Third driven pulleys 806 and fourth driven pulleys 807 are fixedly connected to the second intermediate roller 504 and the third intermediate roller 505 respectively. A third transmission belt 808 is drivingly connected between the third driving pulley 805 and the third driven pulley 806 and the fourth driven pulley 807.

[0054] During operation, after the second motor 801 is started, its output shaft drives the second driving pulley 802 to rotate. The second driving pulley 802 is drivingly connected to the second driven pulley 803 through the second transmission belt 804, thereby driving the central roller 502 to rotate.

[0055] When the central roller 502 rotates, the third driving pulley 805 fixedly connected thereto also rotates. The third driving pulley 805 is drivingly connected to the third driven pulley 806 on the second intermediate roller 504 and the fourth driven pulley 807 on the third intermediate roller 505 through the third transmission belt 808, thereby driving the second intermediate roller 504 and the third intermediate roller 505 to rotate.

[0056] Since the first edge roller 507, the second edge roller 508, the third edge roller 509, the fourth edge roller 510 and the first intermediate roller 503, the second intermediate roller 504, the third intermediate roller 505, the fourth intermediate roller 506 are connected by the glue-removing mesh belt 511, driven by the rotation of the central roller 502, the second intermediate roller 504 and the third intermediate roller 505, the other rollers and the glue-removing mesh belt 511 will also rotate cooperatively, so that the base belt 900 after spraying glue is continuously rolled and conveyed between each roller and the glue-removing mesh belt 511, completing processes such as lamination and drying.
