Description

Technical Field

[0001] This utility model belongs to the fields of materials science and surface treatment technology, and specifically relates to a production device for processing sodium naphthalene in PTFE thin films. Background Technology

[0002] Polytetrafluoroethylene (PTFE) is known as the "king of plastics" due to its unique molecular structure and properties, but it also has extremely low surface energy (approximately 0.018 J / m²). 2 Its chemical inertness makes it difficult to be wetted by adhesives, making it one of the most difficult synthetic materials to bond. Traditional PTFE sodium naphthalene treatment processes require nitrogen protection to prevent oxidation and failure of the treatment solution, but nitrogen equipment is expensive, the process is complex, the safety is poor, and there is a risk of leakage.

[0003] Therefore, in view of the problems of high equipment cost, complex process, poor safety and leakage risk of existing technology, there is a need to provide a PTFE film sodium naphthalene processing production device. Utility Model Content

[0004] This invention provides a PTFE film sodium naphthalene processing production device to solve the problems of high equipment cost, complex process, poor safety and leakage risk in existing technologies.

[0005] This utility model is achieved through the following technical solution: it includes an unwinding mechanism for winding PTFE film, a sodium naphthalene treatment liquid tank, a cleaning pneumatic pressure roller, a cleaning tank, and a winding mechanism. The unwinding mechanism is disposed on the sodium naphthalene treatment liquid tank, which is used to soak the wound PTFE film. The cleaning pneumatic pressure roller is disposed on the cleaning tank, which is used to press the PTFE film into the cleaning tank. The winding mechanism is disposed adjacent to the cleaning tank. After the unwinding mechanism releases the PTFE film, it is pressed into the cleaning tank by the cleaning pneumatic pressure roller and then wound up by the winding mechanism.

[0006] To better realize this utility model, further optimizations are made to the above structure, wherein the sodium naphthalene treatment liquid tank is a U-shaped tank and the sodium naphthalene treatment liquid tank is mounted on the chassis.

[0007] To better realize this utility model, further optimizations are made to the above structure. The unwinding mechanism includes a first electric rotating shaft, which is located above the sodium naphthalene treatment liquid tank.

[0008] To better realize this utility model, further optimization is made to the above structure. A guiding device is provided between the cleaning pneumatic pressure roller and the unwinding mechanism. The guiding device includes multiple smooth guide rollers, which are fixedly mounted on the machine housing.

[0009] To better realize this utility model, the above structure is further optimized by providing two limiting rings at intervals on the multiple smooth guide rollers, and the two limiting rings restrict the movement of the PTFE film to be processed along the width direction.

[0010] To better realize this utility model, further optimization is made to the above structure. The cleaning pneumatic pressure roller includes two upper guide rollers and three lower guide rollers, with one upper guide roller provided above the space between every two lower guide rollers.

[0011] To better realize this utility model, further optimizations are made to the above structure. The cleaning tank includes three water tanks, which are arranged in sequence, and each lower guide roller is partially disposed in each water tank.

[0012] To better realize this utility model, the above structure is further optimized by including a residual liquid cleaning mechanism. The residual liquid cleaning mechanism is located after the cleaning tank and includes a fixed guide roller and a movable guide roller, which are located in the same longitudinal plane.

[0013] To better realize this utility model, further optimizations are made to the above structure. The winding mechanism is a second electric rotating shaft, which is located after the residual liquid cleaning mechanism. One end of the second electric rotating shaft is located inside the machine housing, and the second end of the second electric rotating shaft is located outside the machine housing.

[0014] Compared with the prior art, this utility model has the following advantages:

The unwinding mechanism is disposed on the sodium naphthalene treatment liquid tank, which is used to soak the wound PTFE film. The cleaning pneumatic pressure roller is disposed on the cleaning tank, which is used to press the PTFE film into the cleaning tank. The winding mechanism is disposed adjacent to the cleaning tank. After the unwinding mechanism releases the PTFE film, it is pressed into the cleaning tank by the cleaning pneumatic pressure roller, and then wound up by the winding mechanism.

[0016] The above structure places the unwinding mechanism on the sodium naphthalene treatment liquid tank, ensuring that the surface of the PTFE film to be treated is in complete contact with the sodium naphthalene treatment liquid, resulting in uniform treatment and stable adhesion of the treated PTFE film.

[0024] Example 1:

[0025] A PTFE film sodium naphthalene treatment production apparatus includes an unwinding mechanism 1 for winding PTFE film, a sodium naphthalene treatment liquid tank 2, a cleaning pneumatic pressure roller, a cleaning tank 7, and a winding mechanism. The unwinding mechanism 1 is disposed on the sodium naphthalene treatment liquid tank 2, which is used to soak the wound PTFE film. The cleaning pneumatic pressure roller is disposed on the cleaning tank 7, which is used to press the PTFE film into the cleaning tank 7. The winding mechanism is disposed adjacent to the cleaning tank 7. After the unwinding mechanism 1 releases the PTFE film, it is pressed into the cleaning tank 7 by the cleaning pneumatic pressure roller and then wound up by the winding mechanism.

[0026] The above structure places the unwinding mechanism 1 on the sodium naphthalene treatment liquid tank 2, so that the surface of the PTFE film to be treated is in complete contact with the sodium naphthalene treatment liquid, the treatment is uniform, and the PTFE film after treatment has stable adhesion. Moreover, the PTFE film sodium naphthalene treatment production device only needs to consist of the unwinding mechanism 1, the sodium naphthalene treatment liquid tank 2, the guiding device, the cleaning pneumatic pressure roller, and the cleaning tank 7. The structure is simple, the equipment cost is low, the process is simple, the processing time is short, and the sodium naphthalene treatment liquid will not evaporate and become ineffective in a short time. Therefore, there is no need to equip it with nitrogen equipment, and there is no risk of nitrogen leakage. The safety performance is high.

[0027] The sodium naphthalene treatment solution tank 2 is a U-shaped tank, which is mounted on the chassis. The U-shaped design of the sodium naphthalene treatment solution tank 2 matches the shape of the PTFE film wound by the unwinding mechanism 1, resulting in higher utilization of the sodium naphthalene treatment solution.

[0028] The unwinding mechanism 1 includes a first electric rotating shaft, which is positioned above the sodium naphthalene treatment liquid tank 2. Positioning the first electric rotating shaft above the sodium naphthalene treatment liquid tank 2 allows the wound PTFE film to be immersed in the sodium naphthalene treatment liquid, resulting in more complete treatment of the PTFE film and better wetting effect.

[0029] A guiding device is provided between the aforementioned pneumatic cleaning roller and the aforementioned unwinding mechanism 1. The guiding device includes multiple smooth guide rollers 3, which are fixedly mounted on the aforementioned chassis. The PTFE film is guided through the sodium naphthalene treatment tank 2 to avoid wrinkles or misalignment. The guide rollers at this location are polished to reduce frictional damage to the PTFE film.

[0030] Each of the aforementioned smooth guide rollers 3 is provided with two limiting rings 4 spaced apart, which restrict the movement of the PTFE film to be processed along the width direction. The two limiting rings 4 can be adjusted by rotation.

[0031] The aforementioned pneumatic pressure roller for cleaning includes two upper guide rollers 5 and three lower guide rollers 6, with one upper guide roller 5 positioned above every two lower guide rollers 6. The two upper guide rollers 5 and three lower guide rollers 6 increase the contact area between the PTFE film and the cleaning tank 7.

[0032] The aforementioned cleaning tank 7 comprises three water tanks arranged sequentially, with each lower guide roller 6 partially disposed within each of the aforementioned water tanks. The cleaning liquid is stored to remove residual sodium naphthalene treatment solution and byproducts (such as NaH and NaOH) from the PTFE surface. The three water tanks perform the following cleaning processes in sequence: First-stage cleaning: rinsing with room temperature water to remove most of the treatment solution; Second-stage cleaning: circulating 90℃ hot water cleaning; Third-stage cleaning: continuous circulation of 95℃ water to thoroughly remove residues.

[0033] It also includes a residual liquid cleaning mechanism 8, which is located after the cleaning tank 7. The residual liquid cleaning mechanism 8 includes a fixed guide roller and a movable guide roller, which are located on the same longitudinal plane. The treated PTFE film is squeezed by the fixed guide roller and the movable guide roller to squeeze out the residual liquid.

[0034] The aforementioned winding mechanism 9 is a second electric rotating shaft, which is located after the aforementioned residual liquid cleaning mechanism 8. One end of the second electric rotating shaft is located inside the machine housing, and the other end is located outside the machine housing. The winding mechanism 9 is driven by a servo motor and is synchronized with the tension and speed of the unwinding mechanism 1.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
