Description

Technical Field

[0001] This utility model relates to a fabric straightening and guiding device for a fabric setting machine. Background Technology

[0002] A fabric setting machine is a device used to set the shape of fabric after weaving. It primarily eliminates internal stress in the fabric through heat, mechanical force, or chemical methods, stabilizing its dimensions, shape, and physical properties to achieve a smooth, crisp, or specific style. During operation, the fabric is continuously under traction and subject to various mechanical movements and production operations, often resulting in deviation, skewing, and bending. Therefore, to ensure the fabric maintains its correct position within the setting machine and prevents edge shifting, wrinkling, or curling, thus guaranteeing setting quality and production efficiency, a web guiding device is installed. Existing web guiding devices, such as the web guiding and correcting mechanism for a setting machine disclosed in Chinese Utility Model Patent CN219859741U, include a base, an integrated rotating roller, segmented rotating rollers, a web guiding frame, a hinged bracket, and a servo cylinder. In this design, an integrated rotating roller and segmented rotating rollers are mounted parallel to each other on a web-aligning frame. The web-aligning frame is mounted on a base via a hinged bracket. A servo cylinder is located at one end of the web-aligning frame and drives it to swing up and down, thereby correcting the fabric clamped between the integrated and segmented rotating rollers. However, in this prior art, one end of the web-aligning frame is supported by the servo cylinder, while the other end is suspended in the air. This results in poor stability and vibration, making the fabric more prone to shifting. Utility Model Content

[0003] The purpose of this utility model is to provide a fabric guiding and correction device for a fabric setting machine, including a base frame and a roller frame. A pair of vertically parallel rotating rollers are mounted on the roller frame. The base frame is equipped with a left support mechanism for supporting the left end of the roller frame and a right support mechanism for supporting the right end of the roller frame. The left support mechanism includes a first crank, a first connecting rod, a first slider, and a first guide rail. The lower end of the first crank is hinged to the base frame, and the upper end of the first crank is hinged to the left end of the roller frame. The first guide rail is fixedly mounted on the base frame, and the first slider is slidably mounted on the first guide rail. The lower end of the first connecting rod... The first connecting rod is hinged to the first slider, and the upper end of the first connecting rod is hinged to the middle of the first crank. The right support mechanism includes a second crank, a second connecting rod, a second slider, and a second guide rail. The lower end of the second crank is hinged to the base frame, and the upper end of the second crank is hinged to the right end of the roller frame. The second guide rail is fixedly mounted on the base frame, and the second slider is slidably mounted on the second guide rail. The lower end of the second connecting rod is hinged to the second slider, and the upper end of the second connecting rod is hinged to the middle of the second crank. The base frame is also provided with a drive mechanism for driving the first slider or the second slider to reciprocate.

[0004] This invention achieves simultaneous support at both ends of the roller frame by setting up left and right support mechanisms, ensuring the stability of the support, preventing the roller frame from shaking, and avoiding interference with the fabric conveying. Furthermore, the left and right support mechanisms are rationally designed, and the up-and-down swing control of the roller frame can be achieved with a single drive mechanism, making implementation convenient.

Detailed Implementation

[0012] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution.

[0013] like Figures 1 to 5 The illustrated fabric guiding device for a fabric setting machine includes a base frame 10 and a roller frame 20. A pair of vertically parallel rotating rollers 30 are mounted on the roller frame 20, and the fabric (not shown in the figure) is held between the pair of rotating rollers 30.

[0014] The base frame 10 is equipped with a left support mechanism 40 for supporting the left end of the roller frame 20 and a right support mechanism 50 for supporting the right end of the roller frame 20.

[0015] The left support mechanism 40 includes a first crank 401, a first connecting rod 402, a first slider 403, and a first guide rail 404. The lower end of the first crank 401 is hinged to the base frame 10, and the upper end of the first crank 401 is hinged to the left end of the roller frame 20. The first guide rail 404 is fixedly mounted on the base frame 10, and the first slider 403 is slidably mounted on the first guide rail 404. The first guide rail 404 is used to guide the sliding of the first slider 403. The lower end of the first connecting rod 402 is hinged to the first slider 403, and the upper end of the first connecting rod 402 is hinged to the middle of the first crank 401.

[0016] The right support mechanism 50 includes a second crank 501, a second connecting rod 502, a second slider 503, and a second guide rail 504. The lower end of the second crank 501 is hinged to the base frame 10, and the upper end of the second crank 501 is hinged to the right end of the roller frame 20. The second guide rail 504 is fixedly mounted on the base frame 10, and the second slider 503 is slidably mounted on the second guide rail 504. The second guide rail 504 is used to guide the sliding of the second slider 504. The lower end of the second connecting rod 502 is hinged to the second slider 503, and the upper end of the second connecting rod 502 is hinged to the middle of the second crank 501.

[0017] The base frame 10 is also provided with a drive mechanism for reciprocating the sliding of the first slider 403 or the second slider 503. In this embodiment, the drive mechanism is shown to be located on the left side of the base frame and is used to drive the first slider 403 to slide. Of course, the drive mechanism can also be configured to drive the second slider 503 to slide.

[0018] This technical solution achieves simultaneous support at both ends of the roller frame by setting up left and right support mechanisms, ensuring support stability, preventing roller frame vibration, and avoiding interference with fabric conveying. Furthermore, the left and right support mechanisms are rationally designed, and the up-and-down swing control of the roller frame can be achieved with a single drive mechanism, facilitating implementation.

[0019] The left support mechanism 40 and the right support mechanism 50 are symmetrical. This technical solution is reasonably designed and easy to implement.

[0020] Both the left support mechanism 40 and the right support mechanism 50 are crank-slider mechanisms. Using a crank-slider mechanism facilitates implementation.

[0021] The driving mechanism is used to drive the first slider 403 to slide back and forth.

[0022] The drive mechanism includes a lead screw 60, a nut 70, and a motor 80;

[0023] The lead screw 60 is rotatably mounted on the base frame 10, and the lead screw 60 is parallel to the first guide rail 404.

[0024] The nut 70 is fixedly installed on the first slider 403. In this embodiment, the nut 70 is fixedly installed on the bottom of the first slider 403, and the nut 70 is sleeved on the lead screw 60. The nut 70 and the lead screw 60 form a lead screw nut pair.

[0025] The motor 80 is mounted on the base frame 10, and the output shaft of the motor 80 is fixedly connected to the lead screw 60 so that the motor 80 drives the lead screw 60 to rotate.

[0026] The disclosed drive mechanism has a simple structure and is easy to implement. Using a lead screw and nut drive ensures the accuracy of controlling the sliding motion and allows for nut self-locking.

[0027] In this embodiment, the reciprocating sliding of the first slider is achieved by the motor driving the lead screw to rotate forward or reverse.

[0028] The working process of this utility model can be seen below.

[0029] When the fabric is biased towards the left end of the roller frame, such as Figure 4 As shown, the first slider is driven to slide to the left in the figure, so that the left end of the roller frame is higher than the right end. The fabric held by the rotating roller slides down to the right in the figure under the action of gravity, so that the fabric returns to the center position of the roller frame.

[0030] When the fabric is biased towards the right end of the roller frame, such as Figure 5 As shown, the first slider is driven to slide to the left in the figure, so that the left end of the roller frame is lower and the right end is higher. The fabric held by the rotating roller slides down to the left in the figure under the action of gravity, so that the fabric returns to the center position of the roller frame.
