Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a garment fabric conveying device with automatic deviation correction function. Background Technology

[0002] In the garment fabric production process, fabric conveying is a crucial step. With the increasing automation in the garment manufacturing industry, the requirements for precision in fabric conveying are becoming increasingly stringent. However, in actual production, due to factors such as uneven fabric texture, unstable unwinding tension, and installation errors of the conveyor rollers, the fabric is prone to lateral shift during conveying. Once the fabric shift exceeds the allowable range, it will not only lead to problems such as pattern misalignment and dimensional deviations in subsequent cutting and dyeing processes, reducing product qualification rates, but may also cause fabric entanglement, equipment malfunctions, and other issues, affecting production efficiency and increasing production costs.

[0003] Currently, some garment manufacturers rely on manual monitoring, where operators observe the fabric conveying status in real time and manually adjust the fabric position upon detecting deviations. This method depends on manual experience, is labor-intensive, and has a slow response time, making it unsuitable for high-speed automated production. Other companies use simple mechanical correction devices, such as those using limit rods to stop the fabric, but these devices have low correction accuracy, cannot adapt to fabrics of different widths and textures, and can easily damage the fabric, failing to effectively solve the problem of fabric conveying deviation. Therefore, there is an urgent need to design a garment fabric conveying device with a high degree of automation, precise correction, and wide applicability. Utility Model Content

[0004] The purpose of this invention is to provide a garment fabric conveying device with automatic correction function to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] An automatic fabric conveying device with automatic deviation correction function includes a base, on the top of which a pair of machine bases are mounted. One side of each machine base is connected to an upper roller and an lower roller via bearings. A first motor is mounted on the back of one of the machine bases, and its output is connected to the lower roller. A straightening member slides between the machine bases on the top of the base. A driving member is embedded in the top of the base, driving the straightening member to move vertically. The straightening member is used to tighten the fabric. A pair of uprights are mounted on the top surface of the base between the base and the straightening member. Photoelectric sensors are mounted on the adjacent sides of each upright. The uprights are symmetrically arranged about the radial line of the upper roller. The photoelectric sensors monitor the fabric deviation in real time, and the driving member automatically adjusts the position of the straightening member to correct the fabric deviation, thereby improving conveying stability and processing accuracy, reducing manual intervention, and adapting to the needs of high-speed automated production.

[0007] Furthermore, the straightening component includes a connecting plate, and two pairs of fixing rods are installed on the top of the connecting plate. A first limiting roller and a pair of second limiting rollers are rotatably connected between the pair of fixing rods from bottom to top. The fabric wound on the feeding roller passes through one of the second limiting rollers, the first limiting roller, and the other second limiting roller in sequence, and is wound around the outside of the unloading roller. By passing through the S-shaped path of the second limiting roller, the first limiting roller, and the second limiting roller, the contact length between the fabric and the limiting rollers is increased, so that there is sufficient friction between the straightening component and the fabric, ensuring that the fabric can move together with the straightening component.

[0008] Furthermore, a sliding groove is provided on the top surface of the base. The driving component includes a threaded sleeve installed at the center of the bottom surface of the connecting plate and a threaded rod rotatably installed inside the sliding groove. The threaded sleeve and the threaded rod are threadedly engaged. The threaded sleeve also slides within the sliding groove. A second motor is installed on the side of the base. The output end of the second motor is connected to the threaded rod. The rotation of the second motor drives the threaded rod to rotate, and the threaded sleeve slides axially within the sliding groove, driving the connecting plate and the limiting roller to move synchronously, thereby achieving precise adjustment of the straightening component.

[0009] Furthermore, the photoelectric sensor includes a transmitter and a receiver. The transmitter continuously emits infrared light, and the receiver receives infrared light in real time. The height of the transmitter is higher than the highest point of the second limiting roller, and the height of the receiver is lower than the lowest point of the first limiting roller. The transmitter and receiver are staggered in height to cover the full width of the fabric, ensuring that the fabric edge deviation is detected in time, thereby improving the sensitivity and accuracy of the correction.

[0010] Furthermore, a pair of connecting blocks are installed on both sides of the base, and a rotating shaft is rotatably connected between the pair of connecting blocks via a coil spring. A dustproof strip is wound around the outside of the rotating shaft. A slot is opened on both sides of the base, and the slot and the slide groove are connected. The free section of the dustproof strip passes through the slot and connects with the threaded sleeve. The threaded rod is located below the slot. The dustproof strip automatically unfolds or rewinds as the threaded sleeve moves axially, blocking the opening of the slide groove, preventing dust and fibers from entering, avoiding jamming between the threaded rod and the threaded sleeve, and extending the service life of the equipment.

[0011] Furthermore, the slots, dustproof belts, and chutes are all the same width. This equal width design ensures that the dustproof belt completely covers the opening of the chutes, avoiding dustproof failure due to dimensional deviations and guaranteeing the reliability of the dustproof effect.

[0012] Furthermore, the second limiting roller and the first limiting roller are of equal length, and the feeding roller and the unloading roller are of equal length. The length of the second limiting roller and the first limiting roller is greater than the length of the feeding roller and the unloading roller. The length of the limiting roller is greater than that of the feeding roller and the unloading roller, so as to ensure that the edge of the fabric is still limited when it exceeds the roller body, avoid edge loss of control, and ensure that the entire width of the fabric can be effectively corrected by tension difference.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the garment fabric conveying device with automatic correction function has a driving component that drives the straightening component to move along the fabric conveying axis, and achieves precise correction by changing the tension difference on both sides of the fabric. The photoelectric sensor monitors the deviation in real time, and the automated control reduces manual intervention, thereby improving the conveying stability and processing accuracy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a garment fabric conveying device with automatic correction function, including a base 1, a pair of machine bases 2 mounted on the top of the base 1, an upper roller 3 and an lower roller 4 respectively connected to one side of the pair of machine bases 2 via bearings, a first motor mounted on the back of one of the machine bases 2, the output end of the first motor being connected to the lower roller 4 via transmission, a straightening member sliding between the pair of machine bases 2 on the top of the base 1, a driving member embedded in the top of the base 1, the driving member driving the straightening member to move vertically, the straightening member being used to tighten the fabric, a pair of uprights 5 mounted on the top surface of the base 1 between the base 1 and the straightening member, photoelectric sensors mounted on the sides of the pair of uprights 5 that are close to each other, the pair of uprights 5 being symmetrically arranged along the radial line of the upper roller 3, the first motor driving the lower roller 4 to rotate, driving the fabric conveying, the photoelectric sensor transmitter 6 and receiver 7 detecting fabric deviation, the system controlling the second motor 13 to drive the threaded rod 12 to rotate, the threaded sleeve 18 driving the straightening member to slide axially, adjusting the fabric tension difference, and correcting the deviation.

[0022] Specifically, the connection circuit of the photoelectric sensor and the second motor 13 refers to an overload speed limiting device based on a photoelectric sensor, which discloses the connection method between the photoelectric sensor and the motor, according to announcement number CN202608700U.

[0023] As an embodiment of this utility model, the straightening member further includes a connecting plate 8. Two pairs of fixing rods 9 are installed on the top of the connecting plate 8. A first limiting roller 10 and a pair of second limiting rollers 11 are rotatably connected between the pair of fixing rods 9 from bottom to top. The fabric wound on the feeding roller 3 passes through one of the second limiting rollers 11, the first limiting roller 10, and the other second limiting roller 11 in sequence, and is wound around the outside of the unloading roller 4. The fabric is wound in an S-shaped path. When the straightening member moves along the axial direction, the position of the limiting rollers changes, causing the tension on both sides of the fabric to be unequal. For example, if the tension on the left side increases, it will drive the fabric to move to the left, offsetting the original offset and realizing the correction.

[0024] As an embodiment of this utility model, the top surface of the base 1 is provided with a sliding groove 19. The driving component includes a threaded sleeve 18 installed at the center of the bottom surface of the connecting plate 8 and a threaded rod 12 rotatably installed inside the sliding groove 19. The threaded sleeve 18 and the threaded rod 12 are threadedly engaged. The threaded sleeve 18 also slides in the sliding groove 19. A second motor 13 is installed on the side of the base 1. The output end of the second motor 13 is connected to the threaded rod 12. The rotation of the second motor 13 drives the threaded rod 12 to rotate. The threaded sleeve 18 slides axially in the sliding groove 19, driving the connecting plate 8 and the limiting roller to move synchronously, thereby achieving precise adjustment of the straightening component.

[0025] In one embodiment of this utility model, the photoelectric sensor further includes a transmitter 6 and a receiver 7. The transmitter 6 continuously emits infrared light, and the receiver 7 receives the infrared light in real time. The height of the transmitter 6 is higher than the highest point of the second limiting roller 11, and the height of the receiver 7 is lower than the lowest point of the first limiting roller 10. When the fabric shifts and blocks the infrared light, the signal of the receiver 7 changes, and the system determines the direction and distance of the shift accordingly, controlling the drive component to operate.

[0026] As an embodiment of this utility model, a pair of connecting blocks 15 are installed on both sides of the base 1. A rotating shaft 16 is rotatably connected between the pair of connecting blocks 15 via a coil spring. A dustproof strip 14 is wrapped around the outside of the rotating shaft 16. A slot 17 is opened on both sides of the base 1. The slot 17 is connected to the slide groove 19. The free section of the dustproof strip 14 passes through the slot 17 and is connected to the threaded sleeve 18. The threaded rod 12 is located below the slot 17. When the threaded sleeve 18 moves, it pulls the dustproof strip 14. The coil spring drives the rotating shaft 16 to rotate, so that the dustproof strip 14 always covers the slide groove 19, preventing impurities from entering the slide groove 19.

[0027] As an embodiment of this utility model, the slot 17, the dustproof belt 14, and the slide 19 are of equal width. The dustproof belt 14 can completely block the slide 19 during axial movement, and can effectively prevent impurities from entering no matter where the straightening part moves.

[0028] As an embodiment of this utility model, the second limiting roller 11 and the first limiting roller 10 are of equal length, the feeding roller 3 and the unloading roller 4 are of equal length, and the length of the second limiting roller 11 and the first limiting roller 10 is greater than the length of the feeding roller 3 and the unloading roller 4. Even if the fabric width is greater than the feeding roller 3 and the unloading roller 4, the two ends of the limiting roller still support the edge fabric. When the straightening member moves axially, the entire width of the fabric generates a tension difference synchronously, thereby achieving overall correction.

[0029] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
