Description

Technical Field

[0001] This utility model relates to the field of woven plastic fabric technology, and in particular to a double-sided guide unfolding device for woven plastic fabric composite. Background Technology

[0002] Woven fabric is made of interwoven warp and weft yarns. The warp yarns are arranged along the direction of fabric travel, while the weft yarns are arranged laterally, forming a stable mesh structure. To improve the waterproof and windproof performance of woven fabric, a film is coated on its surface during production. The process involves first unfolding the woven fabric, and then laminating it with the film to achieve waterproof and windproof properties. Due to the mesh structure of the woven fabric, the sides tend to converge towards the center when unfolded, affecting the lamination effect. Utility Model Content

[0003] The purpose of this utility model is to provide a double-sided guiding unfolding device for woven plastic composites, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0005] This utility model provides a double-sided guiding unfolding device for woven plastic fabric composite, including two spaced-apart extension mechanisms. The two extension mechanisms are provided with a central reference line along the width direction of the woven plastic fabric. Each extension mechanism includes an extension seat, a first roller, and a second roller. The first roller and the second roller are rotatably mounted on the extension seat and are coaxially mounted on the extension seat. A side passage gap is provided between the first roller and the second roller. The axial direction of the first roller is set at an angle to the width direction of the woven plastic fabric, so that the two sides of the woven plastic fabric extend outward. The two first rollers are axially symmetrical about the central reference line.

[0006] The beneficial effects of this utility model are:

[0007] Both sides of the woven fabric pass through the first roller and the second roller. Because the first roller and the second roller are set at an angle relative to the woven fabric, the first roller and the second roller apply outward force to the woven fabric on both sides, so that the two sides of the woven fabric extend to both sides, which achieves the effect of unfolding the woven fabric, making the woven fabric flatter, less prone to wrinkles, and also better for lamination.

[0008] As a further improvement to the above technical solution, the extension mechanism also includes a base, the extension seat is rotatably disposed on the base, and an angle adjustment fixing component is provided between the base and the extension seat. The angle adjustment fixing component is used to adjust the angle between the axial direction of the first roller and the width direction of the woven fabric to change the outward extension force of the first roller and the second roller on both sides of the woven fabric.

[0009] As a further improvement to the above technical solution, the angle adjustment fixing component includes an arc-shaped groove and a fixing screw. The arc-shaped groove is provided in the extension seat, and the fixing screw passes through the arc-shaped groove and is threadedly connected to the base to abut and fix the extension seat to the base.

[0010] As a further improvement to the above technical solution, the interval between the two extension mechanisms can be adjusted.

[0011] As a further improvement to the above technical solution, the unfolding device also includes a fixing rod, which is perpendicular to the forward direction of the woven fabric, and the extension mechanism is adjustablely fixed to the fixing rod.

[0012] As a further improvement to the above technical solution, the extension mechanism is slidably fixed to the fixed rod.

[0013] As a further improvement to the above technical solution, the unfolding device also includes an adjustment and fixing component, which includes a sliding seat and a locking screw. The sliding seat is fixedly disposed on the extension mechanism and slidably disposed on the fixing rod. The locking screw is threadedly connected to the sliding seat and abuts against the fixing rod.

[0014] As a further improvement to the above technical solution, the cross-section of the fixing rod is circular.

[0015] As a further improvement to the above technical solution, the side edges between the first roller and the second roller are adjustable via a gap.

[0016] As a further improvement to the above technical solution, the extension seat is provided with a driving structure, which is connected to the end of the first roller to drive the first roller away from or closer to the second roller. Attached Figure Description

[0024] Reference Figures 1 to 2 The following are embodiments of the double-sided guiding unfolding device for plastic woven fabric composite:

[0025] The double-sided guide unfolding device for woven plastic fabric composite includes two extension mechanisms 100, a fixed rod 200, and an adjusting and fixing assembly. The extension mechanism 100 includes an extension seat 110, a base 140, a first roller 120, and a second roller 130. The fixed rod 200 has a circular cross-section. The adjusting and fixing assembly includes a sliding seat 300 and a locking screw 400. The sliding seat 300 is fixedly installed at the bottom of the extension mechanism 100. The sliding seat 300 has a groove that matches the fixed rod 200. The groove is fitted onto the fixed rod 200. The locking screw 400 is threadedly connected to the sliding seat 300 and abuts against the fixed rod 200. After the locking screw 400 is loosened, the sliding seat 300 can slide along the fixed rod 200 to adjust the interval between the two extension mechanisms 100 to accommodate woven plastic fabrics of different widths. Meanwhile, the sliding seat 300 can rotate around the fixed rod 200 and be locked by the locking screw 400, thereby adjusting the angle of rotation of the extension mechanism 100 around the fixed rod 200 and thus adjusting the guiding direction of the extension mechanism 100. There can be only one fixed rod 200, with both extension structures slidably fixed to it. This allows the two extension machines to be positioned on the same straight line, applying force more evenly to both sides of the woven fabric and making installation more convenient.

[0026] In some other embodiments, two fixing rods 200 may be provided, with one fixing rod 200 fixing one extension mechanism 100. The fixing rods 200 can be installed on the frame of the plastic woven fabric processing device, which can reduce the length of the fixing rods 200 and reduce installation costs. For more secure fixing, the number of fixing components can be set to two or three. In some other embodiments, the cross-section of the fixing rod 200 may also be rectangular or other shapes, or the fixing rod 200 may be a slide rail structure.

[0027] Two extension mechanisms 100 are set with reference to the center baseline in the width direction of the woven fabric. The extension seat 110 is rotatably mounted on the base 140, which has two support plates. The two ends of the second roller 130 are rotatably mounted on the two support plates of the extension seat 110. The second roller 130 is coaxially arranged with the first roller 120. A side passage gap is provided between the first roller 120 and the second roller 130, through which the side of the fabric passes. The axial direction of the first roller 120 is set at an angle to the width direction of the woven fabric, causing the two sides of the woven fabric to extend outward. Generally, the guide roller is parallel to the width direction of the woven fabric, and the force applied by the guide roller is the forward direction of the woven fabric. In this application, the axial direction of the first roller 120 is not perpendicular to the forward direction of the woven fabric, and it can apply an outward force. The specific angle is determined according to factors such as the material and width of the woven fabric. The two first rollers 120 are axially symmetrical about the central reference line, and the magnitude of the force exerted by the first roller 120 and the second roller 130 on the outward extension of the two sides of the woven fabric is the same.

[0028] Because the distance between the first roller 120 and the second roller 130 is fixed, it cannot accommodate woven fabrics of different thicknesses, leading to problems such as wrinkles, jamming, or excessive stretching during the unfolding process. Therefore, in this embodiment, the extension base 110 is equipped with a drive structure 170. The first roller 120 is mounted on the output shaft of the drive structure 170, and the drive structure 170 is connected to the end of the first roller 120 via a transmission connection. The drive structure 170 can drive the first roller 120 away from or closer to the second roller 130, adjusting the gap between the first roller 120 and the second roller 130. In some other embodiments, the first roller 120 may also be rotatably mounted on the extension base 110.

[0029] Specifically, the drive structure 170 employs a cylinder, which allows for adjustable spacing between the first roller 120 and the second roller 130. The spacing between the first roller 120 and the second roller 130 can be adjusted according to different thicknesses of woven fabric, thereby improving the adaptability of the unfolding device. The cylinder is connected to the control system via a solenoid valve. The control system automatically adjusts the cylinder's stroke based on preset woven fabric thickness parameters, thus precisely adjusting the spacing between the first roller 120 and the second roller 130. This design features fast adjustment speed and high precision, enabling dynamic adjustment during continuous production.

[0030] In some other embodiments, the side gap between the first roller 120 and the second roller 130 can also be adjusted manually. Specifically, a manual adjustment mechanism is provided on the sides of the first roller 120 and the second roller 130. This mechanism includes an adjusting screw and a locking nut. The adjusting screw passes through the extension seat 110, with one end connected to the end of the first roller 120 and the other end equipped with a handwheel. The locking nut is mounted on the adjusting screw and is used to fix the adjusted position. During operation, the locking nut is loosened, the handwheel is rotated, and the adjusting screw pushes the first roller 120 to move, adjusting it to the desired gap; then the locking nut is tightened to fix the position of the first roller 120. This manual adjustment mechanism has a simple structure.

[0031] To accommodate different thicknesses of woven plastic fabric and ensure better unfolding effect, an angle adjustment fixing component is provided between the base 140 and the extension seat 110. This angle adjustment fixing component is used to adjust the angle between the axial direction of the first roller 120 and the width direction of the woven plastic fabric, thereby changing the outward extension force applied by the first roller 120 and the second roller 130 to both sides of the woven plastic fabric.

[0032] Specifically, a rotating shaft 180 is provided on the base 140, and the extension seat 110 is rotatably mounted on the base 140 around the rotating shaft 180. The angle adjustment fixing component includes two arc-shaped grooves 150 and a fixing screw 160. The arc-shaped grooves 150 are formed on the extension seat 110, and their arc direction is located on a circle with the rotating shaft 180 as the center. The fixing screw 160 passes through the arc-shaped grooves 150 and is threadedly connected to the base 140, thereby abutting and fixing the extension seat 110 to the base 140. When it is necessary to adjust the angle, the fixing screw 160 can be loosened first, the entire extension seat 110 can be rotated to the desired angle, and then the fixing screw 160 can be tightened to fix it.

[0033] In some other implementations, the manual screws are replaced with electric push rods, which are connected to the extension seat 110 via a transmission mechanism. An angle sensor is also added to detect the rotation angle and electrically control the angle adjustment, thereby improving the adjustment efficiency and accuracy.

[0034] The principle of this invention is as follows: During the unfolding process of the woven fabric, both sides of the fabric pass through the first roller 120 and the second roller 130. Because the first roller 120 and the second roller 130 are inclined relative to the woven fabric, they apply outward forces to both sides of the fabric, causing the sides of the fabric to extend laterally, thus unfolding the fabric. This arrangement not only allows the woven fabric to unfold effectively but also makes it smoother, less prone to wrinkles, and provides better conditions for subsequent lamination processes.

[0035] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
