Description

Technical Field

[0001] The invention relates to the technical field of fabric conveying, in particular to a tension-adjustable textile fabric conveying device. Background Art

[0002] The transportation of textile fabrics usually starts from spinning, weaving or other processing steps. In these links, the fabrics may need to be transported by conveyor belts, roller conveyors or other special equipment. These equipment can accurately control the speed and direction of the fabric transfer to ensure the stability and efficiency of the production process. The transportation of fabrics during the processing is also very critical. For example, the fabrics need to pass through different conveying systems in the dyeing, printing, finishing and packaging links to ensure that each process can be carried out according to the predetermined quality standards.

[0003] In the prior art, textile fabrics are only conveyed normally. In this process, it is inevitable that the textile fabrics will be wrinkled and the different conveying speeds will cause the textile fabrics to be in a loose state, which will easily lead to defective products. Therefore, a conveying device with wrinkle removal function and textile fabric tension adjustment function is needed.

[0004] The invention with authorization announcement number CN114524312B discloses a textile fabric conveying device, which drives the flattening wheel on the piston rod to move through a connecting rod. Under the conduction of the air pump, the gas enters the air guide column through the air transmission pipe, and then enters the installation cylinder from the connecting pipe and the air guide pipe, driving the piston rod to move to one side through the piston block, and the piston rod drives the flattening wheel on one side to flatten the fabric, thereby achieving the purpose of removing wrinkles from the textile fabric.

[0005] The above-mentioned device can achieve the purpose of dewrinkling textile fabrics, but the device does not have clamping devices on both sides of the dewrinkling component, and the textile fabric is not under a suitable tension state. When dewrinkling the textile fabric, the transversely untensioned textile fabric is likely to interfere with the longitudinal dewrinkling process, resulting in incomplete dewrinkling and reducing the dewrinkling efficiency of the textile fabric. Moreover, the device does not have a tension adjustment mechanism, and is unable to adjust the tension of the textile fabric. The function is relatively single and cannot effectively improve the conveying efficiency of the textile fabric. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The limit pin is driven to move in the limit groove by the eccentric wheel, and the baffle control mechanism controls the movement direction of the limit pin in the limit groove to improve the transmission efficiency of the device. When the first limit rod moves from away from the textile fabric to close to the textile fabric, the limit pin is guided from the horizontal end to the upper limit groove through the baffle control mechanism. When the limit pin is at the uppermost position, the tensioning felt block is in an extended state under the elastic force of the spring (at this time, the first fixed block is at the highest point, and the tensioning felt block does not contact the surface of the textile fabric), and moves to the other horizontal end through the baffle control mechanism, that is, the transmission rod moves to the point closest to the center of the textile fabric, and then when the first limit rod moves from close to the textile fabric to away from the textile fabric, due to The baffle control mechanism has a unidirectional control effect, so that the limit pin is guided from the horizontal end to the lower limit groove through the baffle control mechanism. When the limit pin is at the bottom, the tensioning felt block is in a compressed state under the elastic force of the spring (at this time, the first fixed block is at the lowest point, and the tensioning felt block contacts and presses the surface of the textile fabric), driving the textile fabric to move synchronously from the center to the outside (due to the simultaneous movement to the outside, the surface of the textile fabric will not be greatly displaced), the wrinkles on the textile fabric are flattened, and then the limit pin returns to the initial position through the baffle control mechanism, thereby completing the process of flattening the wrinkles on the textile fabric, and the symmetrically arranged reciprocating telescopic device improves the efficiency of flattening the surface of the textile fabric;

[0020] Water is injected into the gravity adjustment space through a water pump, so that the piston moves toward the side close to the multi-stage electric push rod. The second laser positioning sensor monitors the moving distance of the piston. Since the gravity adjustment space is a regular cylindrical space, the water in the gravity adjustment space can be controlled (water is injected into the gravity adjustment space when the weight is insufficient, and the multi-stage electric push rod is started to reduce the water in the gravity adjustment space when the weight is overweight), so as to roughly control the weight of the clamping gravity adjustment roller, which is convenient for the initial tensioning operation of the textile fabric. In addition, the water in the gravity adjustment space is evenly filled, and the eccentric rotation will not occur when the clamping gravity adjustment roller rotates, thereby reducing the friction between the distance adjustment device and the long limit hole;

[0021] The movable seat is driven to slide on the second limit rod by rotating the threaded control hand wheel, and then the distance between the two clamping gravity adjusting rollers is adjusted, so that the two clamping gravity adjusting rollers clamp the textile fabric, and at the same time, the first clamping roller and the second clamping roller perform the initial clamping on the textile fabric, so that the textile fabric between the first clamping roller, the second clamping roller and the two clamping gravity adjusting rollers is in a tensioned state under the gravity of the two clamping gravity adjusting rollers, so that the two clamping gravity adjusting rollers can squeeze and flatten the wrinkle-removed textile fabric, and the subsequent device can process the textile fabric;

[0022] The servo motor is used as a power source to adjust the height of the third transmission roller, press down the surface of the textile fabric, and then achieve secondary tension adjustment of the textile fabric, so that the textile fabric is in a suitable tension state.

The stop pin 134 is at the most When the fabric is in the downward position, the tensioning felt block 138 is in a compressed state under the elastic force of the spring 137 (at this time, the first fixed block 135 is at the lowest point, and the tensioning felt block 138 is in contact with and pressed against the surface of the textile fabric), driving the textile fabric to move synchronously from the center to the outside (due to the simultaneous movement outward, the surface of the textile fabric will not undergo a large displacement), the wrinkles on the textile fabric are flattened, and then the limit pin 134 returns to the initial position via the baffle control mechanism 122, thereby completing the process of flattening the wrinkles on the textile fabric, and the symmetrically arranged reciprocating telescopic device 13 improves the efficiency of flattening the surface of the textile fabric.

[0040] The baffle control mechanism 122 includes a shaft baffle 1221 and a torsion spring 1222 . A groove is provided on the fixed frame 12 . The torsion spring 1222 is installed in the groove.

The textile fabric passes between the two clamping gravity adjustment rollers 222, and is fed to the third transmission roller 36 through the second transmission roller 221. Then, the textile fabric is fed from the third transmission roller 36 to the last second transmission roller 221 (the power of the textile fabric is provided by an additional device, and this device is only responsible for wrinkle removal and tension adjustment of the textile fabric). The drive motor 14 is started, and the power is transmitted to the reciprocating telescopic device 13 through the gear transmission mechanism 15, the first sprocket chain transmission mechanism 16 and the second sprocket chain transmission mechanism 17, and the eccentric wheel 1 31 drives the limiting pin 134 to move in the limiting groove 121. When the first limiting rod 136 moves from away from the textile fabric to close to the textile fabric, the limiting pin 134 is guided from the horizontal end to the upper limiting groove 121 through the baffle control mechanism 122. When the limiting pin 134 is at the uppermost position, the tensioning felt block 138 is in an extended state under the elastic force of the spring 137 (at this time, the first fixing block 135 is at the highest point, and the tensioning felt block 138 does not contact the surface of the textile fabric), and moves to the other horizontal end through the baffle control mechanism 122, that is, the transmission rod 133 moves to the position closest to the center of the textile fabric.

Adjust the distance between the two clamping gravity adjusting rollers 222 so that the clamping gravity adjusting rollers 222 clamp the textile fabric. The first laser positioning sensor 212 monitors the height of the distance adjusting device 23 at the two clamping gravity adjusting rollers 222. When the height of the distance adjusting device 23 is at the high point threshold, open the electromagnetic control valve 28 on the fifth pipe 253, start the water pump 27, so that the water in the water tank 29 is injected into the gravity adjustment space 2224 in the clamping gravity adjusting roller 222 through the collecting pipe 26, the first pipe 241 and the third pipe 251, increase the weight of the clamping gravity adjusting roller 222, make the clamping gravity adjusting roller 222 descend, drive the textile fabric to adjust the tension and flatten, and close the water pump 27 and the electromagnetic control valve 28 after the adjustment is completed.When the height of the distance adjustment device 23 is at the low point threshold, the electromagnetic control valve 28 on the second pipe 242 is opened, the multi-stage electric push rod 2225 in the clamping gravity adjustment roller 222 is started, and the piston 2223 is pushed to move.
