[0003] In the production process of Teslin mesh fabric, the inspection of surface defects is a crucial step. Currently, fabric inspection machines are typically used to test the fabric. These machines provide the necessary hardware environment for inspection, continuously unfolding the fabric in sections with ample light. Workers visually inspect the fabric to identify defects and color differences. The machine automatically records the length and arranges the rolls. High-performance inspection machines are equipped with electronic defect detection devices, using computer statistical analysis to assist in the inspection process and print out the results.

[0004] Currently, Chinese patent CN206308519U discloses a fabric inspection machine, which includes a frame, a fabric feeding mechanism, a fabric rolling mechanism, a fabric brushing mechanism, and an air blowing mechanism.

When the roller 192 abuts against the top surface of the wedge-shaped block, the top rod 191 abuts against the transmission rod 183 and rotates the transmission rod 183 around the lock rod 181.

[0070] The cloth inspection machine in the production process step S5 of the seat mesh cloth is specifically implemented as follows: when inspecting the stacked new cloth, the clamping pipes 332 of the two clamping jaws 33 are put into the inside of the two ends of the winding roller 34, then the clamping pipes 332 of the two clamping jaws 33 are inserted into the mounting holes 22, then the worker drives high-pressure gas to flow into the hollow sections of the connecting pipes 331 and the clamping pipes 332 from the valve cores 335, so that the pressing blocks 333 move away from the central axes of the connecting pipes 331 and the clamping pipes 332, until the pressing blocks 333 abut against the side walls of the mounting holes 22 and the inner wall of the winding roller 34, thereby fixing the winding roller between the two rotating discs 31. Then the output shaft of the limiting cylinder 21 is controlled to extend by the electric control system, the rotating disc 31 is turned over, the side wall of the clamping table 10 abuts against the output shaft of the cylinder, and the opening two 12 faces the placing platform 2.

[0071] Then the stacked cloth is pushed into the placing platform 2, the worker applies force to the push rod 6233 to move away from the sliding rod 6232, the push rod 6233 drives the spring one 6231 to stretch and deform, and the push rod 6233 drives the sliding rod 6232 to slide in the positioning hole 9 away from the sliding groove 7, until the end of the push rod 6233 completely exits the sliding groove 7 and enters the inside of the connecting plate 621, at this time the opening one 8 is no longer blocked by the sliding rod 6232. Then the chuck unit 622 is slid out of the sliding groove 7 from the opening one 8. The guide rail one 6227 of the chuck unit 622 slides in the guide groove one 16 synchronously in the middle of the sliding process, thereby playing an auxiliary guiding role. Then the worker rotates the upper clamping plate 6221 in the chuck unit 622 around the hinge joint between the upper clamping plate 6221 and the lower clamping plate 6222, so that the pin 6223 exits the insertion slot 6224, and then the pin 6223 passes through the gap between the meshes and is reinserted into the insertion slot 6224, thereby clamping the mesh fabric between the upper clamping plate 6221 and the lower clamping plate 6222.

[0072] Subsequently, the worker reinserts the clamp unit 622 into the sliding groove 7 by the same principle as above, so that the sliding rod 6232 limits the clamp unit 622 from escaping from the sliding groove 7 at the opening one 8. Subsequently, the power source 613 “second motor” is started by the electric control system, the chain 614 drives the cloth clamping assembly 62 to move synchronously with the chain 614, so that the cloth clamping assembly 62 moves together with the cloth, so that the cloth passes through a plurality of cloth guide rollers 51, the cloth inspection platform 4 and gradually approaches the winding mechanism 3. At the same time that the cloth clamping assembly 62 approaches the winding assembly, the unlocking unit 19 fixed between the connecting plate 621 and the rack 1 gradually approaches the trigger unit 20 “wedge block”, and then the roller 192 of the unlocking unit 19 abuts against the inclined surface of the wedge block, the inclined surface of the wedge block forces the roller 192 to drive the ejector rod 191 to move away from the connecting plate 621, the ejector rod 191 synchronously drives the push rod 6233 away from the connecting plate 621, the push rod 6233 synchronously drives the sliding rod 6232 to gradually move away from the sliding groove 7 and the spring one 6231 to stretch and deform, so that the opening one 8 is gradually unblocked. At the same time, the clamp unit 622 enters the interface slot 11, and the guide rail two 6228 on the top of the upper clamp plate 6221 slides in the guide groove two 17.

[0073] When the roller 192 rotates to the top surface of the wedge block, the opening one 8 is completely opened, and at this time the side wall of the clamp unit 622 abuts against the end of the interface slot 11 away from the opening two 12. With the continuous movement of the connecting plate 621, the clamp unit 622 is slowly pushed out of the sliding groove 7 because it is blocked by the interface slot 11. At the same time, the ejector rod 191 abuts against the transmission rod 183, forcing the transmission rod 183 to start rotating around the central axis of the lock rod 181, the transmission rod 183 drives the lock rod 181 to rotate together, the lock rod 181 drives the lock head 184 to gradually approach the inlet slot 14 from the lock slot 15, until the lock head 184 completely enters the inlet slot 14, the compressed spring two 182 pushes the lock rod 181 to move from the guide hole 13 to the interface slot 11, until the end of the lock head 184 abuts against the side wall of the interface slot 11. At this time, through the cooperation of the spring two 182 and the lock rod 181, the cooperation of the lock rod 181 and the guide hole 13, the lock rod 181 blocks the opening two 12, preventing the clamp unit 622 from sliding out of the opening two 12.

[0074] Subsequently, the chain 614 drives the roller 192 to no longer abut against the wedge block, the ejector rod 191 returns to the initial position under the influence of gravity, the spring one 6231 restores, driving the push rod 6233 and the sliding rod 6232 to reapproach the sliding groove 7, until the opening one 8 is reblocked by the sliding rod 6232. Subsequently, the chain 614 brings the connecting plate 621 and the locking unit 623 in the cloth clamping assembly 62 back to the placement platform 2 for the next use.

[0075] Then the output shaft of the control limiting cylinder 21 is retracted and the driving member 32 "first motor" is started, which drives the rotating disc 31 to rotate, and the rotating disc 31 drives the clamping jaw 33 to rotate together, so that the limited winding roller 34 rotates together. At the same time, the protruding clamping table 10 on the side wall of the rotating disc 31 rotates synchronously with the rotating disc 31, so that the cloth can be automatically wound on the surface of the winding roller 34.

[0076] When the winding is completed, the worker releases the gas in the clamping jaw 33, removes the rotating disc 31, so that the finished cloth is unloaded, rotates the lower clamping plate 6222 around the hinge shaft between the upper clamping plate 6221 and the lower clamping plate 6222, so that the insertion slot 6224 and the insertion pin 6223 are separated, and then the chuck unit 622 is removed from the cloth and put back into the sliding groove 7, completing the whole process of the new cloth inspection.

[0077] Of course, the above is only a typical example of the present application, in addition to this, the present application can have other various specific embodiments, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
