Description

Technical Field

[0001] The present invention relates to the technical field of cloth winding devices, and in particular to a cloth winding limiting device. Background Art

[0002] In the textile industry, fabric winding is a crucial step in the production process. Its quality directly affects subsequent fabric storage, transportation, and further processing. With the continuous development of the textile industry, the requirements for fabric winding are also increasing. Not only is it necessary to ensure the efficiency of winding, but also the quality of the fabric after winding. For example, the flatness, tightness, and neatness of the winding of the fabric are all of great concern.

[0003] However, the existing fabric retracting device still has the following two shortcomings in use: 1. Lack of effective tension adjustment makes it difficult to dynamically adjust the tension according to the actual situation of the fabric in real time. The tension can only be roughly controlled by the operator's experience. This makes the fabric winding quality uneven and cannot stably meet the needs of high-quality production. 2. Fabrics are prone to deviation during the conveying and winding process, especially for fabrics that are wider or thinner. Slight external interference or equipment installation errors may cause the fabric to deviate from the normal winding path. Current winding equipment often lacks a reliable limiting structure, or the limiting structure is not flexible and accurate enough, making it difficult to achieve a good limiting effect for fabrics of different widths. Summary of the Invention

[0004] The present invention relates to a winding limiting device for fabric, so as to solve the problems that the current winding device lacks effective tension regulation, is difficult to dynamically adjust the tension according to the actual situation of the fabric in real time, and is prone to deviation during the fabric conveying and winding process.

[0008] Furthermore, the upper end surface of the sleeve is a horizontal structure, and a through locking hole is provided on the upper end surface of the sleeve.

[0009] Furthermore, a transverse sliding groove is provided on the upper end surface of the limiting roller, a fastening block is slidably mounted inside the transverse sliding groove, and scale lines are provided on the outer circumference of the limiting roller.

[0010] Furthermore, a fastening screw is fixedly mounted on the upper end surface of the fastening block, the fastening screw is clamped in a locking hole on the surface of the sleeve, and a nut is connected to the surface of the fastening screw.

[0011] Furthermore, a cavity is provided inside the tension adjustment roller, a notch is provided in the middle of the upper end surface of the tension adjustment roller, and a controller is installed in the middle of the cavity inside the tension adjustment roller.

[0012] Furthermore, three pressure sensors are installed on the lower end surface of the tension adjustment roller, the pressure sensors are electrically connected to the controller, and the controller is electrically connected to the second motor.

[0013] The present invention provides a convenient cloth retraction limiting device, which has the following beneficial effects: 1. Two symmetrical first motors are set on the placement plate. When the cloth outside the reel reaches a certain weight, the pull plate can be rotated by pulling out the fixed pin to swap the positions of the two reeling shafts, so that the cloth can be reeled in uninterruptedly. After that, the worker can remove the reeled cloth from the reel, which greatly ensures the continuity of the cloth reeling work, avoids frequent shutdowns to replace reeling shafts, and effectively improves the overall reeling efficiency.

[0014] 2. The outer side of the limiting roller is sleeved with a slidable sleeve, and the inner end of the sleeve is provided with a limiting plate that can fit with the two ends of the cloth. During the cloth winding process, the sleeve can be manually and flexibly slid to the appropriate position according to the actual width of the cloth and other requirements, and the cloth is limited by the limiting plate, which effectively avoids the left and right swing and deviation of the cloth when it moves forward, ensuring that the cloth can be accurately transported and wound along the established route, ensuring the neatness and quality of the winding. Moreover, through the cooperation of the fastening block, fastening screw, locking hole and nut, the sleeve can be firmly fixed in the adjusted position on the limiting roller. At the same time, the scale lines on the outer circumference of the limiting roller facilitate accurate observation and further fine adjustment of the position of the sleeve, making the limiting function more accurate and reliable.

[0015] 3. The tension adjustment roller is equipped with a pressure sensor, a controller and a second motor electrically connected to the controller. When working, the tension adjustment roller contacts the fabric, and the pressure sensor can sense the tension of the fabric in real time and transmit the corresponding signal to the controller. The controller judges whether the tension meets the preset requirements. If not, it can control the second motor to drive the tension adjustment roller to rotate accordingly. By changing the position of the tension adjustment roller and other methods, the fabric tension is adjusted to keep it within the appropriate range at all times. This not only ensures the flatness of the fabric during the winding process and avoids wrinkles and other situations that affect the fabric quality, but also helps to improve the overall quality of the fabric after winding, making the wound fabric more compact and regular, which is convenient for subsequent storage, transportation and use.

[0016] 4. The main body of the operating frame is a U-shaped structure. Two guide rollers on the same horizontal plane are fixedly installed between the vertical plates at both ends. The cloth passes under the limit roller and then passes over the two guide rollers for winding. The guide rollers can provide stable and accurate conveying guidance for the cloth, ensuring that the cloth can enter the winding process steadily and smoothly, reducing problems such as jamming and uneven friction caused by unstable cloth conveying routes, and further ensuring the orderly progress and winding quality of the entire winding work.
