Description

[0001] This case is a divisional application of patent application 202210957634.0 (filed on August 10, 2022, entitled "A Manufacturing Process for Insulating Tape"). Technical Field

[0002] This invention relates to the field of insulating tape technology, and more particularly to an insulating tape manufacturing apparatus. Background Technology

[0003] Insulating tape specifically refers to the tape used by electricians to prevent electrical leakage and provide insulation. Also known as insulating cloth or tape, it consists of a base tape and a pressure-sensitive adhesive layer. The base tape is generally made of cotton cloth, synthetic fiber fabric, or plastic film, while the adhesive layer is made of rubber with tackifying resins and other compounding agents, resulting in good adhesion and excellent insulation performance. Insulating tape possesses good insulation, voltage resistance, flame retardancy, and weather resistance, making it suitable for wire splicing, electrical insulation, and thermal protection.

[0004] In the existing technology, due to the viscosity of the tape and the speed requirements of the equipment, it is difficult to achieve uniformity in adhesive application, and the thickness of the adhesive layer is not uniform and stable enough. If the existing bottlenecks are overcome, the performance and stability of the tape will be further improved. Given the high utilization rate of insulating tape, this will have a significant impact. Summary of the Invention

[0005] Based on the technical problems existing in the background art, the present invention proposes an insulating tape manufacturing device.

[0006] This invention proposes an insulating tape manufacturing apparatus, including an adhesive applicator. The adhesive applicator includes a first and a second ring channel, which are symmetrically arranged in a circular or elliptical shape. The radial cross-sections of the first and second ring channels are rectangular. Atomized adhesive liquid inlet, a compressed air inlet, and a recovery rinsing channel are symmetrically arranged along the tangential direction on the first and second ring channels, respectively. The outer walls of the first and second ring channels abut against each other at one point, and the abutment point is through to form a confluence cavity. A rotating roller is arranged opposite to each other on both sides of the confluence cavity. The two rotating rollers, which are perpendicular to the plane of the first and second ring channels, are partially embedded in the confluence cavity to form a reduced diameter section. Two backing papers are pressed together by a pressing roller, and then dynamically pass through the confluence cavity laterally along the flow direction of the atomized adhesive liquid. The atomized adhesive liquid dynamically adheres to the side of the backing papers that are not pressed together to form an adhesive layer, and is separated by a separating roller after passing through the confluence cavity. The other two backing papers are stretched around the surfaces of the two rotating rollers and move dynamically with the rotation of the rotating rollers. The atomized adhesive liquid dynamically adheres to the outer side of the backing papers to form an adhesive layer.

[0007] The amount of adhesive applied is controlled by adjusting the moving speed of the base paper. A small guide roller is provided at the rear outlet of the confluence chamber to guide the base paper through and reduce the overflow of atomized adhesive. Heating devices are provided in the first and second ring channels to heat the internal atomized adhesive and prevent it from condensing into droplets. The roller group is also equipped with a temperature regulating device to promote the solidification of the attached adhesive. Arc-shaped baffles are rotatably provided at the connection between the recycling rinsing channel and the first and second ring channels. The arc-shaped baffles initially form the arc-shaped outer wall of the first or second ring channel, and when rotated downwards, they connect the first or second ring channel to the recycling rinsing channel and block the first or second ring channel.

[0008] The adhesive recovery method of the adhesive application device is as follows: after a certain period of time or when the adhesive mist concentration in the first and second ring channels is detected to be too high, the arc-shaped baffle is rotated at a certain angle to partially open the recovery rinsing channel, and part of the atomized adhesive is flushed out along the recovery rinsing channel to the adhesive recovery container for recycling. During this process, since the arc-shaped baffle does not completely block the first and second ring channels, the adhesive application process will not be interrupted.

[0009] The cleaning method of the adhesive applicator is as follows: one of the atomized adhesive inlet or the compressed air inlet is used as the rinsing liquid inlet, while the other inlet and the recovery rinsing channel are sealed. At the same time, the inlet and outlet of the confluence chamber and the gap between the rotating roller and the confluence chamber are sealed. A special rinsing liquid is injected under pressure and circulates in the first and second ring channels. After rinsing, the arc-shaped baffle is rotated, opening the recovery rinsing channel and blocking the first and second ring channels. Under inertia, the rinsing liquid flows out from the recovery rinsing channel. After completion, compressed air is introduced into the first and second ring channels through the compressed air inlet to discharge the residual rinsing liquid. After completion, the heating device is turned on to heat the first and second ring channels, causing the residual rinsing liquid to evaporate, and the evaporated steam is extracted through the extraction pipe.

[0010] The device also includes a winding device, which comprises a base plate, a strip plate, a cylinder, a punch, a slide, a knife holder, a transfer post, and a winding wheel. The base plate and the strip plate are arranged perpendicularly at a 90-degree angle. The cylinder, punch, slide, reset key, transfer post, and winding wheel are all mounted on the base plate. The base plate is provided with a slide frame, and the side wall of the slide slides horizontally on the outer wall of the slide frame. The outer wall of the punch slides on the inner wall of the slide. The ends of the punch and the knife holder are arranged opposite each other. The transfer post is arranged parallel to both sides of the punch and the knife holder. The winding wheel is symmetrically arranged on both sides of the transfer post.

[0011] The cutter holder consists of two opposing rollers, with the end of the punch horizontally inserted into the gap between the rollers. The side of the belt plate has a belt inlet groove, and the groove direction is consistent with the tangent direction of the side of the roller away from the punch.

[0012] This includes an integrated mixing and reaction device; the integrated mixing and reaction device includes an outer cylinder, an inner cylinder rotatably fitted inside the outer cylinder, and a stirring shaft fitted at the center of the inner cylinder; a hollow ring is fixed to the upper end of the outer cylinder; the hollow ring is rotatably and sealed to the inner cylinder and communicates with the inside of the inner cylinder; an air inlet and an air outlet are provided on the hollow ring; the air inlet and the air outlet are respectively connected to the inside of the inner cylinder through the hollow ring; a motor base is provided above the stirring shaft; a motor is fixed inside the motor base; the motor drives the stirring shaft to rotate through a drive shaft; a central gear is fixedly fitted outside the drive shaft; The central gear drives a planetary gear to rotate; the outer ring of the planetary gear drives the inner cylinder to rotate in the opposite direction through multiple connecting rods; multiple hydraulic telescopic rods are inclined around the outer circumference of the motor base; the front ends of the hydraulic telescopic rods are hinged to the motor base, jointly driving the motor base to dynamically deflect; a bearing disk is provided on the lower end face of the outer cylinder; the fixed disk of the bearing disk is fixedly connected to the outer cylinder; the lower ends of the inner cylinder and the stirring shaft are fixed on the movable disk of the bearing disk; the upper end of a universal joint is hinged to the fixed disk of the bearing disk, and the lower end is hinged to a fixed support; several smooth protrusions are provided on the inner wall of the inner cylinder.

[0013] The hydraulic telescopic rod, motor base, and stirring shaft can be raised and lowered by a lifting mechanism; the connecting rod is detachably connected to the inner cylinder; the inner cylinder has a sandwich design with circumferential side walls, including a semiconductor cooling chip group embedded in the middle and heat-conducting plates on both sides.

[0014] A baffle is provided between the stirring shaft and the inner cylinder; the baffle is rotatably and sealingly connected to the outer circumference of the stirring shaft and the inner wall of the inner cylinder; the baffle is located below the central gear and the planetary gear; a discharge port is provided at the bottom of the inner cylinder; and an air extraction port is connected to an air extraction device.

[0015] The mixing reaction method of the integrated mixing reaction device is as follows:

[0016] ①Put the weighed raw materials into the inner cylinder;

[0017] ② The lifting mechanism lowers the hydraulic telescopic rod, motor base, stirring shaft, and baffle to the preset position as a whole; and fixes the connecting rod to the inner cylinder.

[0018] ③ Inert gas, reducing gas, or gas that participates in the reaction can be introduced into the inner cylinder through the air inlet as needed;

[0019] ④ The motor drives the stirring shaft to rotate through the drive shaft, which stirs and mixes the raw material liquid in the inner cylinder. At the same time, the central gear drives the inner cylinder to rotate in the opposite direction through the planetary gear and the connecting rod; the raw material liquid is stirred in the opposite direction by the smooth protrusions on the inner wall of the inner cylinder, and the raw material liquid is stirred and mixed together with the stirring shaft.

[0020] ⑤ While step ④ is being performed or at a certain time, each hydraulic telescopic rod extends and retracts according to a preset program, thereby driving the stirring shaft and driving the inner and outer cylinders to tilt and deflect in different directions through planetary gears and connecting rods.

[0021] ⑥ While step ④ is being performed or at a certain time, the device controller controls the on / off state, current magnitude and current direction of the semiconductor cooling chip group, thereby dynamically adjusting the temperature of the raw material liquid;

[0022] ⑦ While step ④ is being performed, the air pressure inside the inner cylinder can be adjusted in real time by adjusting the air intake and air output based on the air pressure intensity monitored by the air pressure sensor.

[0023] ⑧ After the mixing reaction is completed, the excess gas is first extracted by the air extraction device, and then the raw material liquid is discharged by opening the discharge port; the lifting mechanism lifts the hydraulic telescopic rod, motor base, stirring shaft and baffle to the preset position so that raw materials can be added again or cleaned.

[0024] ⑨ When it is necessary to concentrate the raw material liquid, the temperature of the semiconductor cooling chip group is increased during the stirring process, and the air is slowly drawn out to achieve the purpose of concentrating the raw material liquid.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. This invention uses extrusion tensioning to make the adhesive layer uniform, and through stretching and winding, it effectively improves the surface strength of the insulating tape and the bonding effect of the adhesive layer after stretching.

[0027] 2. The gluing device used in this invention can achieve rapid, continuous, and dynamic simultaneous gluing of four backing papers, and this is achieved through a relatively closed and recyclable environment. It not only has a small and simple structure and stable operation, but also significantly reduces the release of harmful substances in the glue, improves the workshop environment, and protects the health of workers. It can also complete the gluing process more evenly, improve the uniformity and stability of the glue layer thickness, and increase the utilization rate of the glue solution, reducing waste and the emission of harmful substances. It can not only improve production efficiency, production environment, and product quality, but also reduce environmental harm and achieve environmental protection standards in production.

[0028] 3. The gluing device of the present invention forms a narrowed section by combining the bottom paper and the rotating roller. By utilizing the Bernoulli effect and increasing the flow rate, it can not only avoid excessive liquefaction of the glue, but also improve the uniformity of adhesion.

[0029] 4. The gluing device of the present invention can easily control the gluing thickness of the bottom paper by setting the lateral length of the confluence cavity, the arc length of the rotating roller in the confluence cavity, the lateral bottom paper passing speed, and the rotation speed of the rotating roller, and by changing the contact time with the glue mist. This process can be continuously, automatically and stably realized during the movement of the bottom paper. It can be applied to different product designs and process designs, and has high flexibility, stability and adaptability.

[0030] 5. The gluing device of the present invention can also achieve the cleaning function simply and quickly without manual disassembly and cleaning, which not only saves time and manpower for device cleaning and maintenance, but also better ensures the long-term quality stability of the gluing process.

[0031] 6. In the integrated mixing and reaction device of the present invention, the stirring shaft and the inner cylinder rotate in opposite directions simultaneously. Combined with the smooth protrusions on the inner wall of the inner cylinder, it can not only efficiently utilize the large surface area of ​​the inner wall of the inner cylinder, and achieve the mixing effect together with the stirring shaft, but also allow more raw material liquid to be spread evenly on the inner cylinder wall during the mixing process, thereby improving the heat exchange capacity between the inner cylinder and the raw material liquid, improving the efficiency of regulating the temperature of the raw material liquid, and also improving the turbulence during the mixing process of the raw material liquid, improving the mixing effect, reducing the required mixing time, thereby improving production efficiency and reducing costs. Moreover, the use of planetary gear transmission can not only achieve the opposite rotation of the stirring shaft and the inner cylinder through simple transmission, but also, due to the characteristics of planetary gears, the rotation speed of the outer cylinder can be less than the rotation speed of the stirring shaft. This is exactly in line with the characteristics of the device. Since the inner cylinder is heavier than the stirring shaft, the differential speed can avoid excessive load on the motor. And since both the stirring shaft and the inner cylinder have a mixing function, the differential speed can give the raw material liquid a greater tangential shear force, thereby further improving the mixing efficiency.

[0032] 7. The integrated mixing and reaction device of the present invention can achieve dynamic tilting and deflection, thereby further increasing the contact area between the raw material liquid and the inner wall of the inner cylinder, and also achieving a dice-like effect, increasing the mutual convection and turbulence of the raw material liquid, and also avoiding partial raw material... siltation In situations where ingredients are difficult to stir in corners, resulting in insufficient mixing or reaction, this method can make the ingredients in the liquid more evenly distributed in a short time, significantly improving the stirring and mixing effect and efficiency.

[0033] 8. The hollow ring of the integrated mixing and reaction device of the present invention not only does not affect the rotation of the inner cylinder, but also enables gas filling and degassing, thereby allowing efficient adjustment of the type and pressure of gas in the inner cylinder according to specific needs.

[0034] 9. The integrated mixing and reaction device of the present invention adopts a semiconductor cooling chip group, which eliminates the need for complex heat exchange pipelines. It has a simple and compact structure, and can adjust the temperature in both directions with fast adjustment speed and high adjustment accuracy, thus better ensuring the quality of the adhesive.
