Description

Technical Field

[0001] This utility model relates to the field of fabric spreading machines, and more specifically, to a tension adjustment mechanism for an automatic garment spreading machine. Background Technology

[0002] In the garment manufacturing industry, from the early manual fabric laying to the increasingly popular automated fabric laying equipment, the technology of fabric laying machines has been constantly innovating. The garment manufacturing industry has increasingly higher requirements for the flatness, efficiency and fabric tension control of fabric laying. As a key component of the fabric laying machine, the tension adjustment mechanism has also gone through several stages of technological development.

[0003] A search revealed that Chinese Patent Publication No. CN217894642U discloses "a tension-free fabric laying device for fabric laying machine processing, including a fabric laying platform, with driving mechanisms fixedly connected to both sides of the platform in the width direction, and sliding plates fixedly connected to the output ends of the two driving mechanisms. A horizontal plate located above the fabric laying platform is fixedly connected to the upper ends of the two sliding plates. A fabric feeding mechanism is provided on the upper side of the horizontal plate, a tension adjusting mechanism is fixedly connected to one side of the horizontal plate, and a fabric pressing mechanism that cooperates with the upper side of the fabric laying platform is provided on one side of the sliding plate. A positioning mechanism is fixedly connected to one end of the upper side of the fabric laying platform. This utility model can adjust the tension of the fabric until the tension disappears, allowing the fabric to be laid without tension, thus improving the quality of the packaging fabric." However, it still has the following drawbacks:

[0004] Although this device can adjust the tension of the fabric through multiple adjusting rollers, it may be difficult to ensure that each adjustment is completely accurate due to the wide variety of fabrics, especially when the fabric thickness or elasticity is different. Repeated adjustments may be required, which increases the difficulty of operation.

[0005] In production environments where fabric types change frequently, this device may not be able to quickly adapt to the characteristics of different fabrics, especially differences in fabric thickness, elasticity, and softness, resulting in poor flexibility.

[0006] Therefore, we have made improvements to this by proposing a tension adjustment mechanism for an automatic garment spreading machine. Utility Model Content

[0007] The purpose of this invention is to address the problems of cumbersome adjustment processes and poor equipment adaptability in current applications.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] The tension adjustment mechanism of the automatic garment spreading machine is designed to improve the above-mentioned problems.

[0010] The specific details of this utility model are as follows:

[0011] The device includes two sets of frame plates, which serve as supports for the overall device. An adaptive component for automatically adjusting fabric tension is provided between the two sets of frame plates. A guide component for guiding and limiting the adaptive component is provided on one side of each frame plate. Auxiliary components for assisting the adaptive component in adjusting fabric tension are provided on both sides of each adaptive component. A control component is provided on each frame plate to facilitate the adjustment of the control device by the operator.

[0012] The adaptive component includes a telescopic cylinder fixedly installed on the outside of the frame plate. A push rod is installed at the output end of the telescopic cylinder. An adjusting roller is provided between the two sets of frame plates via a bearing. One end of the adjusting roller is connected to the other end of the push rod via a bearing. A tension sensor is sleeved on the other end of the adjusting roller.

[0013] As a preferred technical solution of this utility model, the guide assembly includes a rectangular block that is fixedly connected to both ends of the adjusting roller by bearings. Limiting grooves are provided on the side walls of both sets of frame plates. The rectangular block slides along the limiting grooves. Two sets of horizontal plates are symmetrically bolted to the outer wall of the frame plate away from the telescopic cylinder. Two sets of limiting posts are symmetrically bolted between the two sets of horizontal plates. Connecting rings are bolted to both side walls of the rectangular block. The other end of the connecting ring is sleeved on the limiting post.

[0014] As a preferred technical solution of this utility model, the auxiliary component includes a fixed roller connected to the two sets of frame plates via bearings, the fixed roller is located between the two sets of frame plates, and an arc-shaped plate is bolted to the bottom of the fixed roller.

[0015] As a preferred technical solution of this utility model, the control component includes a mounting plate that is bolted to the side wall of the frame plate, a display panel that is bolted to the mounting plate, the display panel that is electrically connected to the tension sensor, and an operation button that is fixedly provided on one side of the display panel.

[0016] As a preferred technical solution of this utility model, the side walls of the two sets of frame plates are bolted with a frame, and a cloth feeding roller is fixedly installed on the frame.

[0017] As a preferred technical solution of this utility model, a workbench is fixedly connected to one side of the two sets of frame plates, and the workbench is connected to the two sets of frame plates by bolts.

[0018] As a preferred technical solution of this utility model, multiple sets of anti-slip strips are fixedly installed on the workbench, and the multiple sets of anti-slip strips are made of rubber.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the solution of this utility model:

[0021] 1. With the adaptive components in place, when the fabric passes over the surface of the adjusting roller, the tension sensor monitors the tension of the fabric in real time. If the tension is too low, the telescopic cylinder will push the push rod to move. The height of the adjusting roller will move upward along the direction of the frame plate as the push rod extends, applying a greater tensile force to the fabric and gradually increasing the tension of the fabric. This eliminates the need for frequent manual intervention, allowing the fabric spreading machine to operate continuously and stably.

[0022] 2. With the guide component in place, when the telescopic cylinder pushes the push rod to extend and thus drives the adjusting roller to move upward, the rectangular block slides upward in the limiting groove. The slider connected to the limiting column by the connecting ring can effectively prevent the rectangular block from tilting or swaying during the sliding process, enhance the stability of the adjusting roller's movement, and ensure that the tension adjustment process of the fabric is accurate and reliable.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0031] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] like Figure 1 As shown, this embodiment proposes a tension adjustment mechanism for an automatic garment laying machine, including a frame plate 1. There are two sets of frame plates 1, and the two sets of frame plates 1 are used as supports for the overall device. An adaptive component 2 for automatically adjusting the fabric tension is provided between the two sets of frame plates 1. A guide component 3 for guiding and limiting the adaptive component 2 is provided on one side of the frame plate 1. An auxiliary component 4 for assisting the adaptive component 2 in adjusting the fabric tension is provided on both sides of the adaptive component 2. A control component 5 for the operator to adjust the control device is provided on the frame plate 1.

[0035] like Figure 2 As shown, the adaptive component 2 includes a telescopic cylinder 201 fixedly installed on the outside of the frame plate 1. A push rod 202 is installed at the output end of the telescopic cylinder 201. An adjusting roller 203 is mounted on a bearing between the two sets of frame plates 1. The fabric passes over the surface of the adjusting roller 203. One end of the adjusting roller 203 is connected to the other end of the push rod 202 via a bearing. A tension sensor 204 is sleeved on the other end of the adjusting roller 203 for real-time monitoring of the fabric tension. In use, the fabric passes over the surface of the adjusting roller 203. The tension sensor 204 monitors the fabric tension in real time. If the tension is too low, the telescopic cylinder 201 will push the push rod 202 to move. The height of the adjusting roller 203 will move upward along the direction of the frame plate 1 as the push rod 202 extends, applying a greater tensile force to the fabric and gradually increasing the fabric tension. This eliminates the need for frequent manual intervention, allowing the fabric spreading machine to operate continuously and stably.

[0036] like Figure 2and Figure 3 As shown, the guide assembly 3 includes a rectangular block 301 fixedly connected to both ends of the adjusting roller 203 via bearings. Limiting grooves 302 are provided on the side walls of both sets of frame plates 1. The rectangular block 301 slides along the limiting grooves 302. Two sets of horizontal plates 303 are symmetrically bolted to the outer wall of the frame plate 1 away from the telescopic cylinder 201. Two sets of limiting posts 304 are symmetrically bolted between the two sets of horizontal plates 303. Connecting rings 305 are bolted to both side walls of the rectangular block 301, and the other end of the connecting ring 305 is sleeved on the limiting post 304. In use, when the telescopic cylinder 201 pushes the push rod 202 to extend, thereby driving the adjusting roller 203 to move upward, the rectangular block 301 slides upward within the limiting groove 302. The slider connected to the limiting post 304 via the connecting ring 305 effectively prevents the rectangular block 301 from tilting or swaying during sliding, enhancing the stability of the adjusting roller 203's movement and ensuring accurate and reliable fabric tension adjustment.

[0037] like Figure 2 and Figure 4 As shown, the auxiliary component 4 includes a fixed roller 401 connected to the two sets of frame plates 1 via bearings. The fixed roller 401 is located between the two sets of frame plates 1, and an arc-shaped plate 402 is bolted below the fixed roller 401. The fabric passes under the fixed roller 401 and then over the adjusting roller 203. The arc-shaped plate 402 located below the fixed roller 401 prevents the fabric from falling to the ground and coming into contact with dust, debris, etc., when the fabric tension is too low, thus preventing it from becoming contaminated.

[0038] like Figure 4 and Figure 5 As shown, the control component 5 includes a mounting plate 501 bolted to the side wall of the frame plate 1. A display panel 502 is bolted to the mounting plate 501, and the display panel 502 is electrically connected to the tension sensor 204. An operation button 503 is fixedly installed on one side of the display panel 502. When adjusting the tension of the fabric spreading machine, the operating data of the equipment can be clearly observed through the display panel 502, and commands can be issued through the simple and clear operation button 503. The operation is simple and easy to use.

[0039] like Figure 1 As shown, the side walls of the two sets of frame plates 1 are bolted with frames 6, and fabric roll rollers 7 are fixedly installed on the frames 6. When in use, fabric rolls can be placed on the fabric roll rollers 7, and the fabric rolls will be gradually released as the fabric roll rollers 7 rotate.

[0040] like Figure 1 As shown, a workbench 8 is fixedly connected to one side of each of the two sets of frame plates 1. The workbench 8 is connected to the two sets of frame plates 1 by bolts, which allows for quick disassembly and facilitates maintenance and use.

[0041] like Figure 1 As shown, multiple sets of anti-slip strips 9 are fixedly installed on the workbench 8. The multiple sets of anti-slip strips 9 are made of rubber. The anti-slip strips 9 on the workbench 8 can increase the friction with the fabric, prevent the fabric from slipping off the workbench 8, and facilitate subsequent fabric laying operations.

[0042] Specifically, in use, the tension adjustment mechanism of this automatic garment spreading machine works as follows: the fabric is first released from the fabric roll 7, passing over the surfaces of the fixed roller 401 and the adjusting roller 203. The adjusting roller 203 is equipped with a tension sensor 204, which monitors the tension changes of the fabric in real time. When the tension is too low, the tension sensor 204 will detect this situation, and the telescopic cylinder 201 will be activated. The telescopic cylinder 201 pushes the push rod 202 to move, thereby driving the adjusting roller 203 to move upward along the frame plate 1, increasing the tensile force of the fabric and gradually increasing the tension of the fabric. Automatic tension adjustment can be achieved without frequent manual intervention. The rectangular block 301 slides in the limiting groove 302, which can prevent the adjusting roller 203 from tilting and swaying during the movement, enhancing the stability of the moving adjusting roller 203. The fixed roller 401 and the arc plate 402 below it effectively prevent the fabric from contacting the ground when the tension is too low, avoiding contamination of the fabric. The operator can view the tension status of the fabric in real time through the display panel 502. The operation is simple and ensures the accurate operation of the equipment.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
