Description

Technical Field

[0001] This utility model relates to the field of textile fabric trimming technology, specifically a textile fabric trimming machine. Background Technology

[0002] After textile fabrics are produced, their edges often have rough edges with loose threads. Therefore, the edges need to be trimmed to keep the fabric edges flat. In the textile fabric production process, the fabric is usually rolled into a roll. Before the roll is finished and enters the packaging stage, one side of the roll needs to be trimmed to ensure that the subsequent packaging process is standardized and the final product looks neat.

[0003] For example, a textile fabric trimming machine described in patent CN223373375U uses two sets of ironing machines to iron and flatten the conveyed fabric, making the fabric smoother during the trimming process. This ensures that the fabric remains flat before and after trimming, thereby improving the quality of fabric trimming. Furthermore, each set of ironing machines is equipped with lifting and lowering pressure rollers on both sides, allowing the fabric to fit more tightly against the feeding belt during conveying, further enhancing the quality of fabric trimming.

[0004] The existing technology has the following problems: the tension of the textile fabric is actively adjusted by lifting and lowering the pressure roller and combined with braking adjustment. However, when there is a sudden jam in the face-to-face material transmission, the mechanical adjustment structure has a lag in response and cannot adapt to the sudden change in tension at the moment of jam. This can easily lead to localized wrinkles and tears in the fabric due to force imbalance, and even aggravate the wear of the fabric at the jammed area. At the same time, the tension control accuracy of this adjustment method is greatly affected by the stability of the mechanical transmission. When the jam causes the fabric to shift instantaneously, the braking adjustment is difficult to accurately match the real-time tension requirements. Moreover, it lacks dynamic adaptation capability for fabrics of different thicknesses and elasticities, which not only affects the flatness of subsequent processing, but also increases the fabric loss rate.

[0005] Based on this, a textile fabric trimming machine is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a textile fabric trimming machine to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A textile fabric trimming machine includes a transport frame with a rotating frame fixedly connected to each of its two sides. A winding roller is rotatably mounted in the middle of the rotating frame, and a first rotating motor drives the winding roller to rotate. Two first adjusting seats are mounted on the ground of the transport frame, and the two first adjusting seats are rotatably connected to a bidirectional lead screw. The bidirectional lead screw is threadedly connected to a transmission block, and the transmission block is slidably connected to a guide groove. A rotating seat is fixedly connected to the surface of the transmission block, and the rotating seat is rotatably connected to a rotating disk. A stepper motor is installed inside the rotating seat, and the stepper motor drives the rotating disk to rotate. A mounting frame is fixedly connected to the surface of the rotating disk. A telescopic rod is mounted on one side of the mounting frame, and the telescopic rod drives a cutting tool to move. A sewing seat is mounted on the other side of the mounting frame. An adjustment mechanism is mounted on the transport frame, and the adjustment mechanism includes second adjusting seats, with several second adjusting seats fixedly connected to the surface of the transport frame.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: a pressure roller is provided on each side of the second adjusting seat, and the pressure roller is rotatably connected to the inner wall of the transport frame.

[0009] In one alternative: the surface of the second adjusting seat is provided with an adjusting groove, the interior of the adjusting groove is provided with a platform, the surface of the platform is fixedly connected to a fixing block, and the fixing block is rotatably connected to an adjusting roller.

[0010] In one alternative: a guide roller is fixedly connected to the surface of the platform, a limiting block is slidably connected to the guide roller, the limiting block is fixedly connected to the surface of the second adjusting seat, and a limiting disc is provided at the end of the guide roller.

[0011] In one alternative: the limiting block has a threaded hole on its side, and the second adjusting seat has several positioning holes on both sides, with bolts passing through the positioning holes to thread-fix the limiting block.

[0012] In one alternative: a spring is provided on the outside of the guide roller, one end of the spring is fixedly connected to the surface of the platform, and the other end of the spring is fixedly connected to the surface of the limiting block, and the spring presses the fixing block to fit against the inner wall of the second adjusting seat.

[0013] In one alternative: several rotating wheels are rotatably connected to both sides of the platform, and the rotating wheels roll in contact with the adjustment groove.

[0014] In one alternative: the bidirectional lead screw is driven by a second rotary motor, which is mounted on the side of the first adjusting seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a lower pressure roller to stably press down on the textile fabric, effectively reducing wrinkles and deviations during the conveying process, making it closely adhere to the surface of the conveyor belt to maintain stable conveying quality. The second adjustment seat serves as the basic structure for tension adjustment, providing reliable support for subsequent precise adjustment of the surface tension of the textile fabric. The adjustment roller lifts the textile fabric between the two lower pressure rollers and applies uniform pressure, which can make the tension distribution of the fabric more uniform, thereby ensuring the accuracy of subsequent cutting, trimming, folding and sewing operations.

[0016] 2. This utility model provides a stable movement space for the platform through the adjustment groove. The platform is fixedly connected to the fixed block, and the fixed block is rotatably connected to the adjustment roller. When the adjustment roller is subjected to the reaction force of the fabric tension, it can drive the fixed block to move synchronously, thereby driving the platform to move smoothly and realizing the dynamic response of tension adjustment. The bolt passes through the positioning holes at different positions to flexibly adjust the position of the limit block, thereby changing the degree of spring compression and realizing the adjustment roller to adjust the pressure of the textile fabric as needed. It can adapt to the needs of fabrics with different thicknesses and elasticities, increasing the applicability of the equipment.

[0017] 3. During the movement of the platform, the rollers roll in contact with the inner wall of the adjustment groove. The rolling friction replaces the sliding friction, which greatly reduces the movement resistance. This not only makes the movement of the fixed block and the adjustment roller smoother and more fluid, avoiding the phenomenon of jamming that affects the tension adjustment rhythm, but also enhances the support balance of the platform in the adjustment groove, reduces the problem of unilateral force offset, and further improves the support stability of the overall structure, providing a reliable guarantee for the accuracy of tension adjustment of textile fabrics.

A mounting frame 207 is fixedly connected to the surface of the rotating disk 206. A telescopic rod 208 is mounted on one side of the mounting frame 207, driving a cutting tool 209 to move. A sewing seat 210 is mounted on the other side of the mounting frame 207. The transport frame 101 is equipped with an adjustment mechanism, which includes a second adjustment seat 302. Several second adjustment seats 302 are fixedly connected to the surface of the transport frame 101. The transport frame 101 transports textile fabric, and the rotating frame 102 provides rotation conditions for the roll roller 103. The first rotating motor 104 drives the roll roller 103 to rotate to perform roll-up or unroll-up operations on the textile fabric. A pair of roll rollers 103 cooperate to provide conditions for trimming operations. The cutting tool 209 trims the sides of the textile fabric, and the sewing seat 210 performs hemming and sewing operations on the textile fabric. When it is necessary to switch the trimming mode, the bidirectional lead screw 201 is rotated, which drives the two transmission blocks 204 to move away from each other. The stepper motor drives the rotating disk 206 to rotate, which drives the mounting frame 207 to rotate. The mounting frame 207 moves the cutting tool 209 and the sewing seat 210 to different positions. The bidirectional lead screw 201 reverses to reset the transmission blocks 204, thus realizing the switching of the trimming mode. In one embodiment, such as Figure 4 and Figure 5 As shown, a pressure roller 301 is provided on each side of the second adjusting seat 302. The pressure roller 301 is rotatably connected to the inner wall of the transport frame 101. By setting the pressure roller 301, the textile fabric is pressed down so that the textile fabric fits the surface of the conveyor belt and the conveying quality is maintained. In one embodiment, such as Figure 4 and Figure 5 As shown, the second adjusting seat 302 has an adjusting groove on its surface, and a platform 305 is provided inside the adjusting groove. A fixing block 304 is fixedly connected to the surface of the platform 305, and the fixing block 304 is rotatably connected to the adjusting roller 303. The second adjusting seat 302 provides conditions for adjusting the surface tension of the textile fabric.

The adjustment groove provides movement conditions for the platform 305, and the limiting block 306 provides sliding conditions for the guide roller 308. The mutual cooperation between the guide roller 308 and the limiting block 306 guides the movement of the platform 305, providing conditions for adjusting the surface tension of the textile fabric. In one embodiment, such as Figure 5 and Figure 6 As shown, the limiting block 306 has a threaded hole on its side, and the second adjusting seat 302 has several positioning holes 307 on both sides. The bolt passes through the positioning holes 307 to fix the limiting block 306 with threads. The position of the limiting block 306 is adjusted by the bolt passing through the positioning holes 307 at different positions. Adjusting the position of the limiting block 306 provides conditions for applying pressure to the adjusting roller 303. In one embodiment, such as Figure 5 and Figure 6 As shown, a spring 309 is provided on the outside of the guide roller 308. One end of the spring 309 is fixedly connected to the surface of the platform 305, and the other end of the spring 309 is fixedly connected to the surface of the limiting block 306. The spring 309 presses the fixing block 304 against the inner wall of the second adjusting seat 302, and provides continuous pressure to the fixing block 304 through the spring 309. The pressure applied by the spring 309 can be changed by adjusting the position of the limiting block 306, which is convenient for applying pressure to different types of textile fabrics. In one embodiment, such as Figure 5 and Figure 6 As shown, several rotating wheels 401 are rotatably connected to both sides of the platform 305. The rotating wheels 401 roll into the adjustment groove. By setting the inner wall of the rolling wheel 401 to roll into the adjustment groove, the movement of the fixed block 304 is made smoother, and the support stability is improved. In one embodiment, such as Figure 5 and Figure 6 As shown, the bidirectional lead screw 201 is driven by a second rotating motor 211, which is mounted on the side of the first adjusting seat 202.

[0027] The above embodiment discloses a textile fabric trimming machine, wherein the textile fabric is conveyed by a transport frame 101, a rotating frame 102 provides rotation conditions for the winding roller 103, a first rotating motor 104 drives the winding roller 103 to rotate to wind up or release the textile fabric, and a pair of winding rollers 103 cooperate to provide conditions for trimming operations. A cutting tool 209 trims the sides of the textile fabric, and a sewing seat 210 performs hemming and sewing operations on the textile fabric. When switching trimming modes, the bidirectional lead screw 201 is rotated, which drives two transmission blocks 204 to move away from each other. A stepper motor drives a rotating disk 206 to rotate, which drives a mounting frame 207 to rotate to transfer the positions of the cutting tool 209 and the sewing seat 210. The bidirectional lead screw 201 reverses to reset the transmission blocks 204, thus realizing the trimming mode switching. The lower pressure roller 301 presses down on the textile fabric to make it adhere to the surface of the conveyor belt to maintain the conveying quality. The second adjusting seat 302 is used to adjust the surface tension of the textile fabric. The system provides conditions for the adjustment roller 303 to lift the textile fabric between the two lower pressure rollers 301 and apply uniform pressure. The adjustment groove provides movement conditions for the platform 305. The platform 305 is fixedly connected to the fixing block 304, which is rotatably connected to the adjustment roller 303. When the adjustment roller 303 is under pressure, it drives the fixing block 304 to move, which in turn drives the platform 305 to move. The limiting block 306 provides sliding conditions for the guide roller 308. The guide roller 308 and the limiting block 306 cooperate to guide the platform 305 to move and adjust the surface tension of the textile fabric. The bolt passes through the positioning holes 307 at different positions to adjust the position of the limiting block 306, thereby adjusting the pressure on the spring 309 and changing the pressure applied by the adjustment roller 303 to the textile fabric. The spring 309 provides continuous pressure to the fixing block 304 to adapt to different types of textile fabrics. During the movement of the platform 305, the rotating wheel 401 rolls and contacts the inner wall of the adjustment groove, making the movement of the fixing block 304 smoother and improving the support stability.
