Description

Technical Field

[0001] This utility model relates to a waterproof and breathable fabric manufacturing equipment, and more particularly to a PTFE waterproof and breathable film coating and shaping fabric inlet guide device. Background Technology

[0002] PTFE waterproof and breathable membranes contain tens of thousands of capillary pores, which are about one ten-thousandth the size of a water droplet and 700 times larger than a gas molecule. While being waterproof, they also have good breathability and can be used to make waterproof jackets and other waterproof garments.

[0003] When PTFE membranes are manufactured using the phase separation method, liquid raw materials are coated onto a base fabric, which is then fed into a coagulation bath for solidification. Therefore, it is crucial to ensure that the liquid raw materials do not migrate on the base fabric before entering the bath. Furthermore, improper control of the angle at which the base fabric enters the coagulation bath can lead to the formation of air bubbles, which will negatively impact the quality of the final membrane. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fabric guide device for coating and shaping PTFE waterproof and breathable film to improve film quality.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a PTFE waterproof and breathable film coating and shaping fabric inlet guide device, including a number of height-adjustable guide frames arranged in parallel on a first coagulation tank and an inlet roller guide device. The guide frames are provided with guide rollers. The inlet roller guide device includes a movable seat movably arranged on the first coagulation tank and a power mechanism for driving the movable seat to move along the length direction of the first coagulation tank. The movable seat is provided with a fixed guide roller. A roller frame that rotates around the axis of the fixed guide roller is hinged to the movable seat. An inlet adjusting roller is provided on the roller frame. An adjusting and limiting mechanism for adjusting the position of the roller frame is provided on the movable seat.

[0006] As a preferred embodiment, the adjustment and limiting mechanism includes an adjusting worm gear disposed on the roller shaft of the fixed guide roller, an adjusting worm cooperating with the adjusting worm gear rotatably disposed on the movable seat, an adjusting handwheel disposed at the end of the adjusting worm gear, and the roller frame disposed on the roller shaft.

[0007] As a preferred embodiment, the power mechanism includes a pair of guide rails disposed on the opening of the first solidification tank, a drive shaft rotatably disposed on the movable seat, a pair of driving rollers cooperating with the guide rails being sleeved on the drive shaft, a drive motor disposed on the movable seat, a drive worm gear connected to the output shaft of the drive motor, a drive worm wheel cooperating with the drive worm gear being disposed on the drive shaft, and a pair of driven rollers cooperating with the rails being disposed on the movable seat.

[0008] As a preferred embodiment, the movable seat is also provided with a pair of support rollers that cooperate with the track.

[0009] As a preferred embodiment, the drop height of all guide rollers on the first coagulation tank is not less than one-third of the height from the top surface of the coating machine's output roller to the liquid surface of the first coagulation tank.

[0010] The beneficial effects of this utility model are:

[0011] Because the guide frame is equipped with a guide roller, the water inlet roller guiding device includes a movable seat movably mounted on the first coagulation tank and a power mechanism that drives the movable seat to move along the length of the first coagulation tank. The movable seat is equipped with a fixed guide roller, and a roller frame that rotates around the axis of the fixed guide roller is hinged to the movable seat. The roller frame is equipped with a water inlet adjusting roller, and the movable seat is equipped with an adjusting and limiting mechanism for adjusting the position of the roller frame. By adjusting the height of the guide frame, the tension arc of the base fabric is made appropriate, minimizing the flow of the coating material. By rotating the adjusting handwheel to adjust the position of the roller frame, the position of the water inlet adjusting roller changes, thereby changing the angle between the base fabric stretched on the water inlet adjusting roller and the guide roller outside the coagulation tank relative to the horizontal plane. This allows for finding a reasonable angle range for the base fabric to enter the tank to avoid air bubble formation, thus improving the quality of film formation.

[0012] The adjustment and limiting mechanism includes an adjusting worm gear mounted on the roller shaft of the fixed guide roller, an adjusting worm gear rotatably mounted on the movable seat that cooperates with the adjusting worm gear, an adjusting handwheel at the end of the adjusting worm gear, and the roller frame mounted on the roller shaft. The structure is simple and the adjustment is convenient.

[0013] The power mechanism includes a pair of guide rails set on the opening of the first solidification tank, a drive shaft rotatably mounted on the movable seat, a pair of driving rollers that cooperate with the guide rails mounted on the drive shaft, a drive motor mounted on the movable seat, a drive worm gear connected to the output shaft of the drive motor, a drive worm wheel that cooperates with the drive worm gear mounted on the drive shaft, and a pair of driven rollers that cooperate with the rails mounted on the movable seat.

[0014] The moving base is also equipped with a pair of support rollers that cooperate with the track, making the movement of the moving base more stable.

[0015] Since the drop height of all the guide rollers on the first coagulation tank is not less than one-third of the height from the top surface of the coating machine's output roller to the liquid surface of the first coagulation tank, the relatively gentle descent of the base fabric makes it difficult for the material coated on its surface to migrate, thus ensuring the quality of the subsequent finished products.

Detailed Implementation

[0021] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, a PTFE waterproof and breathable film coating and shaping fabric guide device includes three height-adjustable guide frames 2 arranged side by side on a first coagulation tank 18 and a water inlet roller guide device. Guide rollers 3 are provided on the guide frames 2. The drop height of all guide rollers 3 on the first coagulation tank 18 is not less than one-third of the height from the top surface of the coating machine's exit roller to the liquid level in the first coagulation tank 18.

[0023] The water inlet roller guide device includes a movable seat 4 movably mounted on the first solidification tank 18 and a power mechanism that drives the movable seat 4 to move along the length of the first solidification tank 18.

[0024] The power mechanism includes a pair of guide rails 5 disposed on the opening of the first solidification tank 18. A drive shaft 6 is rotatably mounted on the movable seat 4. A pair of driving rollers 7, cooperating with the guide rails 5, are sleeved on the drive shaft 6. A drive motor 1 is mounted on the movable seat 4. A drive worm gear 9 is connected to the output shaft of the drive motor 1. A drive worm wheel 10, cooperating with the drive worm gear 9, is mounted on the drive shaft 6. The movable seat 4 also has at least one pair of driven rollers 11 that cooperate with the rails. The movable seat 4 also has a pair of support rollers 12 that cooperate with the rails.

[0025] The movable seat 4 is provided with a fixed guide roller 13, and a roller frame 14 that rotates around the axis of the fixed guide roller 13 is hinged to the movable seat 4. A water inlet adjusting roller 15 is provided on the roller frame 14, and an adjusting and limiting mechanism for adjusting the position of the roller frame 14 is provided on the movable seat 4.

[0026] The adjustment and limiting mechanism includes an adjusting worm gear 16 mounted on the roller shaft of the fixed guide roller 13, an adjusting worm 17 rotatably mounted on the movable seat 4 to cooperate with the adjusting worm gear 16, an adjusting handwheel 8 at the end of the adjusting worm 17, and the roller frame 14 mounted on the roller shaft.

[0027] Before film formation, the drive motor 1 drives the active roller 7 to rotate, causing the movable seat 4 of the water inlet roller guide device to move to a suitable position. Then, the height of the guide frame 2 is adjusted to ensure the appropriate tension arc of the base fabric, minimizing the flow of the coating material. The position of the roller frame 14 is adjusted by rotating the adjusting handwheel 8, causing the position of the water inlet adjusting roller 15 to change. This changes the angle between the base fabric stretched on the water inlet adjusting roller 15 and the horizontal plane relative to the guide roller outside the coagulation tank, thus finding a reasonable angle range for the base fabric to enter the tank to avoid air bubble formation.

[0028] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
