[0013] 1. In this utility model, by setting an auxiliary device, when the device needs to be used, first pull the pull ring. The movement of the pull ring带动 the sliding plate to move on the surface of the vertical rod. The movement of the sliding plate on the surface of the vertical rod will挤压 the spring, causing the spring to be compressed under force. At the same time, the movement of the sliding plate on the surface of the vertical rod also带动 the insertion rod to move. When the insertion rod moves to a suitable position, insert the mounting plate into the inner part of the horizontal end of the U-shaped mounting bracket. After the mounting plate and the inner part of the horizontal end of the U-shaped mounting bracket are plugged in, release the pull ring. Use the resilience of the spring to make the insertion rod reset. The reset of the insertion rod causes it to insert into the inner part of the jack.

[0014] 2. In this utility model, by setting an adjusting device, when the lining cloth roll needs to adjust the tension during the transmission process, first rotate the rotating wheel. The rotation of the rotating wheel带动 the threaded rod to rotate. Since the threads on the surface of the threaded rod are reverse threads centered on the rotating wheel, when the rotating wheel带动 the threaded rod to rotate, the two moving plates threadedly connected to its surface will move on the surface of the cross bar in the direction of approaching or moving away from each other. The movement of the two moving plates on the surface of the cross bar in the direction of approaching or moving away from each other带动 the two hinge plates to move. The movement of the two hinge plates带动 the cross bar plate to move downward. The downward movement of the cross bar plate带动 the support rod to move downward.

[0025] The specific settings and functions of its auxiliary device 2 and adjustment device 3 will be described in detail below.

[0026] In this embodiment: the surface of the base plate 1 is provided with an auxiliary device 2, which includes two sleeves 201. The two sleeves 201 are fixedly installed on the surface of the base plate 1. The interior of each of the two sleeves 201 is slidably connected with a support rod 202. A crossbar 203 is fixedly installed at the end of the two support rods 202 away from the sleeves 201.

[0027] In this embodiment, the sleeve 201 and the support rod 202 are designed to allow the crossbar 203 to move stably.

[0028] Specifically, two fixing plates 204 are fixedly mounted on the surface of the horizontal bar 203. An encoder 205 with a specification of 1000p / R is fixedly mounted on the surface of one fixing plate 204. Two short rods 206 are fixedly mounted on one side of the surface of the fixing plate 204. A U-shaped mounting bracket 207 is fixedly mounted on the end of the two short rods 206 away from the fixing plate 204. Mounting plates 208 are movably inserted into the two horizontal ends of the U-shaped mounting bracket 207. A line scan camera 209 is fixedly mounted on the surface of the end of the mounting plate 208 away from the horizontal end of the U-shaped mounting bracket 207. The line scan camera 209 is a CIS camera with two built-in light sources distributed at 30 degrees and 60 degrees. The encoder 205 and the line scan camera 209 are electrically connected.

[0029] In this embodiment, the line scan camera 209 is configured to scan and detect defects on the surface of the lining fabric.

[0030] Specifically, uprights 210 are fixedly installed on both the upper and lower surfaces of the U-shaped mounting bracket 207. A sliding plate 211 is slidably connected to the surface of the uprights 210. An insert rod 212 is fixedly installed on the surface of the sliding plate 211. An insertion hole 213 is opened on the surface of the mounting plate 208. A pull ring 214 is fixedly installed on the surface of the sliding plate 211 away from the insert rod 212. The insert rod 212 and the insertion hole 213 effectively limit the mounting plate 208 to be within the horizontal end of the U-shaped mounting bracket 207.

[0031] Specifically, a circular plate 215 is fixedly mounted on the surface of the upright 210 away from the U-shaped mounting bracket 207, and a spring 216 is fixedly mounted between the circular plate 215 and the sliding plate 211. The spring 216 serves to limit the position of the sliding plate 211 on the surface of the upright 210.

[0032] In this embodiment: an adjustment device 3 is provided on the outer wall surface of both sleeves 201. The adjustment device 3 includes two L-shaped plates 31. The two L-shaped plates 31 are fixedly installed on the outer wall surface of the two sleeves 201. A threaded rod 32 is rotatably connected between the two L-shaped plates 31. A rotating wheel 33 is fixedly installed on the surface of the threaded rod 32. The threads on the surface of the threaded rod 32 are opposite to each other with the rotating wheel 33 as the center. When the tension of the lining roll needs to be adjusted during transmission, firstly, the rotating wheel 33 is rotated. The rotation of the rotating wheel 33 drives the threaded rod 32 to rotate. Since the threads on the surface of the threaded rod 32 are opposite to each other with the rotating wheel 33 as the center, when the rotating wheel 33 drives the threaded rod 32 to rotate, the two movable plates 35 connected by the threads on its surface will move closer to or further away from each other on the surface of the crossbar 34. The movement of the two movable plates 35 on the surface of the crossbar 34 drives the two hinge plates 36 to move. The movement of the two hinge plates 36 drives the crossbar 203 to move downward. The downward movement of the crossbar 203 drives the support rod 202 to move downward. At the same time, the downward movement of the crossbar 203 also drives the two fixed plates 204 to move downward. The downward movement of the two fixed plates 204 drives the adjusting roller 37 to move downward. The downward movement of the adjusting roller 37 completes the corresponding tension adjustment operation of the lining. Through the cooperation of the above structures, the position of the adjusting roller 37 can be adjusted, thereby adjusting the tension of the lining and enabling the lining to be transmitted smoothly.

[0033] Specifically, a crossbar 34 is fixedly installed between the two L-shaped plates 31, and two movable plates 35 are threadedly connected to the surface of the threaded rod 32. The movable plates 35 are slidably connected to the threaded rod 32 and the crossbar 34.

[0034] In this embodiment, the threaded rod 32 serves to move the movable plate 35 on the surface of the crossbar 34.

[0035] Specifically, a hinge plate 36 is hinged to the top surface of the movable plate 35, and the end of the hinge plate 36 away from the movable plate 35 is hinged to the crossbar plate 203. An adjusting roller 37 is fixedly installed between the two fixed plates 204.

[0036] In this embodiment, the hinge plate 36 serves to move the horizontal bar 203.

[0037] Working principle: By setting auxiliary device 2, when the device is needed, first pull the pull ring 214. The movement of the pull ring 214 causes the slide plate 211 to move on the surface of the upright 210. The movement of the slide plate 211 on the surface of the upright 210 will compress the spring 216, causing the spring 216 to be compressed. At the same time, the movement of the slide plate 211 on the surface of the upright 210 also causes the insertion rod 212 to move. When the insertion rod 212 moves to the appropriate position, the mounting plate 208 is then inserted into the U-shaped mounting plate. Inside the horizontal end of the U-shaped mounting bracket 207, after the mounting plate 208 and the horizontal end of the U-shaped mounting bracket 207 are inserted, the pull ring 214 is released. The spring force of the spring 216 resets the insertion rod 212, allowing it to insert itself into the insertion hole 213. The insertion rod 212 and insertion hole 213 are connected, thus fixing the mounting plate 208 inside the horizontal end of the U-shaped mounting bracket 207, thereby completing the installation of the line scan camera 209. When the line scan camera 209... After installation, the lining roll is placed on the surface of the unwinding roller 5, and then its open end passes through the upper end face of the two guide rollers 12, then through the lower end face of the adjusting roller 37, and is wound around the surface of the take-up roller 9. Then, the second motor 10 is started, which drives the take-up roller 9 to rotate, thereby completing the transmission of the lining roll. At the same time, during the transmission of the lining roll, the line scan camera 209 can be used to scan and detect defects such as embossing, oil stains, dirt, holes, pinholes, and creases on the surface of the lining. Through the cooperation of the above structure, the purpose of installing the line scan camera 209 is achieved, so that the device can use the line scan camera 209 to scan and take pictures of the surface of the lining. The pictures are transmitted to the image processing module of the control device. The image processing module performs digital analysis on the surface of the lining in the picture, thereby determining whether there are surface defects in the lining. This realizes automated visual inspection of lining surface defects, reduces the labor intensity of workers, and improves the output rate of products. When the tension of the lining roll needs to be adjusted during transmission, firstly, the rotating wheel 33 is rotated. The rotation of the rotating wheel 33 drives the threaded rod 32 to rotate. Since the threads on the surface of the threaded rod 32 are opposite to each other with the rotating wheel 33 as the center, when the rotating wheel 33 drives the threaded rod 32 to rotate, the two movable plates 35 connected by the threads on its surface will move closer to or further away from each other on the surface of the crossbar 34. The movement of the two movable plates 35 on the surface of the crossbar 34 drives the two hinge plates 36 to move. The movement of the two hinge plates 36 drives the crossbar 203 to move downward. The downward movement of the crossbar 203 drives the support rod 202 to move downward. At the same time, the downward movement of the crossbar 203 also drives the two fixed plates 204 to move downward. The downward movement of the two fixed plates 204 drives the adjusting roller 37 to move downward. The downward movement of the adjusting roller 37 completes the corresponding tension adjustment operation of the lining. Through the cooperation of the above structures, the position of the adjusting roller 37 can be adjusted, thereby adjusting the tension of the lining and enabling the lining to be transmitted smoothly.
