Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cloth inspection machines, and in particular to a dust-free cloth winding device with multi-roller synchronous tension control. Background Art

[0002] During the production of cleanroom cloths, when there are systemic risks or quality abnormalities that affect the tensile strength, it is necessary to upgrade from sampling inspection to full inspection. At this time, since the cleanroom cloth has been rolled up, it is necessary to use a cloth inspection machine to rewind the rolled cleanroom cloth to the other side, and perform multiple inspections on the cleanroom cloth during this process. The cloth inspection machine is usually equipped with a multi-roller synchronous tension control winding device to ensure the flatness of the cleanroom cloth during the inspection process, thereby ensuring the inspection accuracy of the cloth inspection machine.

[0003] A variety of sensors are installed on the cloth inspection machine to test the appearance quality, physical properties and cleanliness of the dust-free cloth. Among them, the tensile strength test is a necessary part of the quality control of the dust-free cloth. Standardized testing can ensure that it is not easy to break or shed fibers in actual use, while meeting the functional needs of different industries. The most common method at present is to take a sample, stretch it from multiple directions, and then test the tensile strength of the dust-free cloth. However, if a whole bundle of dust-free cloth needs to be tested, since the current conventional cloth inspection machine can only rewind the dust-free cloth in one direction, it can only test the tensile strength of the dust-free cloth along the rewinding direction. As a result, the cloth inspection machine's tensile strength test of the dust-free cloth is not comprehensive enough, which in turn affects the test results.

[0004] In response to the above problems, the prior art provides some solutions. For example, patent application number: CN202311197982.3 provides a non-woven fabric spunbond web defect detection device and detection method. When the non-woven fabric cuts into the longitudinal guide wheel on the outer surface of the conveyor belt from the side, the longitudinal guide wheel prevents the non-woven fabric from friction in its length direction. The conveyor belt circulates and applies a force from the center of the non-woven fabric to both sides. Here, the force is in the transverse direction of the non-woven fabric, causing transverse tension. The longitudinal tension of this section of non-woven fabric is adjusted by the front and rear torque adjustment wheels. When the longitudinal tension tends to zero, the vertical strength is detected. However, since the non-woven fabric will always have longitudinal tension as long as it is wound up, when the torque adjustment wheel adjusts the longitudinal tension to make the longitudinal tension tend to zero, the non-woven fabric on the side of the torque adjustment wheel close to the winding wheel is already in a state of being wound and straightened. If the torque adjustment wheel is used to offset the tension on the non-woven fabric on this side at this time, the winding wheel will be unable to continue to rotate and wind the non-woven fabric, which will cause the winding wheel to start and stop continuously during operation, affecting the detection speed. Summary of the Invention

[0005] The purpose of the present invention is to provide a dust-free cloth winding device with multi-roller synchronous tension control, so as to solve the problem that the current conventional cloth inspection machine can only wind the dust-free cloth in one direction, and therefore can only detect the tensile strength of the dust-free cloth along the winding direction, resulting in the cloth inspection machine's tensile strength detection of the dust-free cloth is not comprehensive, thereby affecting the test results.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The cam is provided with a plurality of guide rollers, and the cam and the guide rollers are respectively provided with a plurality of guide rollers. The cam and the guide rollers are respectively provided with a plurality of guide rollers. The guide rollers are used to place the dust-free cloth roll. One end of the dust-free cloth passes through the three guide rollers and is connected to the take-up roller. A pressure sensor and an information processing module are provided inside the mounting seat, which is characterized in that a driving component with transverse pneumatic clamps is provided inside the mounting seat, the number of transverse pneumatic clamps is and are respectively located on both sides of the dust-free cloth, the two transverse pneumatic clamps are slidably connected to the mounting seat and are parallel to the dust-free cloth. The driving component is used to control the transverse pneumatic clamps on both sides to clamp the dust-free cloth and move toward both sides of the dust-free cloth respectively. Longitudinal clamps are respectively provided on both sides of the transverse pneumatic clamps, and the longitudinal clamps are used to clamp the dust-free cloth before the transverse pneumatic clamps are started. The pressure sensor is provided on the transverse pneumatic clamps, and the pressure sensor is electrically connected to the transverse pneumatic clamps.

[0008] It is easy to understand that when testing a whole bundle of dust-free cloths, a cloth inspection machine is needed for inspection. However, since the current conventional cloth inspection machine can only rewind the dust-free cloth in one direction, and can only detect the tensile strength of the dust-free cloth along the rewinding direction, the cloth inspection machine is not comprehensive enough in detecting the tensile strength of the dust-free cloth, which affects the test results. This design sets a transverse pneumatic clamp and a longitudinal clamp on the cloth inspection machine. The area between the two longitudinal clamps is the detection area for the tensile strength of the dust-free cloth. When the cloth inspection machine drives the dust-free cloth to rewind, the drive component will drive the longitudinal clamp to clamp the dust-free cloth, so that one section of the dust-free cloth cannot move. At this time, the transverse pneumatic clamp starts to clamp the dust-free cloth, and the drive component drives the transverse pneumatic clamp to move toward both sides of the dust-free cloth. At the same time, the pulling force of the horizontal pneumatic clamp on the dust-free cloth continues to increase. When the pressure sensor on the horizontal pneumatic clamp detects that the pressure reaches the qualified tensile strength of the dust-free cloth, the clamping of the dust-free cloth is released. At this time, the dust-free cloth continues to be reeled in. When the next section of dust-free cloth moves to the detection area, the horizontal pneumatic clamp and the longitudinal clamp continue to repeat the above steps until all dust-free cloths have completed the inspection, and the drive component will also move the dust-free cloth, so that when the longitudinal clamp clamps the dust-free cloth, the unwinding roller can continue to release the dust-free cloth, and the rewinding roller can continue to rewind the dust-free cloth, so that the unwinding roller and the rewinding roller will not stop during the inspection process. Therefore, this design improves the comprehensiveness of the cloth inspection machine's tensile strength detection of the dust-free cloth, thereby improving the inspection quality and detection speed of the cloth inspection machine.

[0009] Preferably, the driving assembly includes a telescopic rod 1, the telescopic rod 1 is rotatably connected to the mounting seat, the mounting seat is provided with a motor, the output end of the motor is connected to the telescopic rod 1, the two sides of the telescopic rod 1 are slidably connected to the telescopic rod 2, the two telescopic rods 2 are rotatably connected to the moving roller 1 and the moving roller 2, and the moving roller 1 and the moving roller 2 are in contact with the dust-free cloth, and two springs 1 are respectively provided between the two transverse pneumatic clamps and the inner wall of the mounting seat, and the two sides of the transverse pneumatic clamps are fixedly connected to a pressing block 1, and the two sides of the moving roller 1 are fixed A left connecting rod is fixedly connected to the movable roller 2, a right connecting rod is fixedly connected to the left connecting rod, a left control rod 1 is fixedly connected to the right connecting rod, and a right control rod 1 is fixedly connected to the left control rod 1 and the right control rod 1. Pressing block 2 is fixedly connected to both the left control rod 1 and the right control rod 1, and pressing block 2 is in contact with pressing block 1. Induction switches are provided on both sides of the transverse pneumatic clamp, and the induction switches are electrically connected to the transverse pneumatic clamp, and the induction switches are used to control the transverse pneumatic clamp to clamp the dust-free cloth, and the left control rod 1 and the right control rod 1 are in contact with two induction switches respectively.

[0010] When the roller is at its lowest position, the dust-free cloth will be stretched downward by the moving roller 2, and the moving roller 1 is at its highest position. At this time, the motor drives the moving roller 2 to move upward, and the moving roller 1 moves downward. At this time, the moving roller 1 and the moving roller 2 will respectively drive the two longitudinal clamping claws to clamp the dust-free cloth, and the moving roller 1 and the moving roller 2 will continue to move. When the winding roller continues to wind the dust-free cloth, the dust-free cloth originally stretched by the moving roller 2 will continue to be wound due to the upward movement of the moving roller 2, and the dust-free cloth released by the unwinding roller on the other side will also be supported by the downward movement of the moving roller 1. After the moving roller 1 and the moving roller 2 move a certain distance, the pressing blocks 2 on both sides of the moving roller 1 will respectively squeeze the pressing block 1 on one side of the two horizontal pneumatic clamps. The pressing blocks 2 on both sides of the moving roller 2 will also squeeze the pressing blocks 1 on the other side of the two horizontal pneumatic clamps, thereby driving the horizontal pneumatic clamps on both sides of the dust-free cloth to move toward both sides, thereby detecting the tensile strength of the dust-free cloth. After the detection, the two horizontal pneumatic clamps release the dust-free cloth, and the moving roller 1 and the moving roller continue to move during the detection process. When the moving roller 1 moves to the lowest point and the moving roller 2 moves to the highest point, the two longitudinal clamps release the dust-free cloth. At this time, since the dust-free cloth on the moving roller 2 is completely rolled up, a section of the dust-free cloth in the detection area will be rolled up onto the moving roller 2, and the dust-free cloth originally on the moving roller 1 will move to the detection area. Therefore, this design can complete the inspection of all dust-free cloths by repeating the above process, and the dust-free cloth in the detection area will not continue to move, thereby improving the detection quality, and the winding roller and the unwinding roller can continue to wind up and release the dust-free cloth without stopping, and the dust-free cloth always remains flat during this process, thereby avoiding repeated starting and stopping of the motor during the detection process, thereby improving the detection accuracy and detection speed.

[0011] Preferably, the longitudinal clamp includes a rotating shaft, and the number of the rotating shafts is 2, two of the rotating shafts are connected to the mounting seat. The two rotating shafts are respectively located on both sides of the dust-free cloth, and the two rotating shafts are fixedly connected with cylindrical splints, and the cylindrical splints are eccentrically connected to the rotating shaft. A torsion spring is arranged between the cylindrical splints and the rotating shaft, and the cylindrical splints on both sides are symmetrically arranged. One end of the two rotating shafts is fixedly connected with a synchronous gear, and the two synchronous gears are meshed with each other. The left control lever 1 and the right control lever 1 are provided with control components, and the control components are respectively connected to the rotating shafts on the two longitudinal clamps and drive the rotating shafts to rotate.

[0012] It is easy to understand that the design is configured by setting the longitudinal clamping jaws. When the moving roller 1 moves downward and the moving roller 2 moves upward, the moving roller 1 and the moving roller 2 will respectively drive the rotating shafts on the two longitudinal clamping jaws to rotate, and the rotating shafts will then drive the cylindrical clamping plates to rotate. At this time, since the axis of the cylindrical clamping plate and the axis of the rotating shaft do not coincide with each other, the cylindrical clamping plate will rotate eccentrically around the axis of the rotating shaft, and the synchronous gears on the two rotating shafts will make the rotation angles of the two cylindrical clamping plates always consistent. During the rotation of the two cylindrical clamping plates, the distance between the two cylindrical clamping plates gradually decreases until the two cylindrical clamping plates clamp the dust-free cloth. At this time, the two cylindrical clamping plates will stop rotating, and when the moving roller 1 moves When it reaches the lowest point and turns back to move upward, and when the moving roller 2 moves to the highest point and turns back to move downward, the cylindrical splint will rotate in the opposite direction and thus loosen the dust-free cloth. In addition, the design sets a torsion spring between the cylindrical splint and the rotating shaft. At the moment when the cylindrical splint loses its clamping force on the dust-free cloth, it will apply a thrust to the cylindrical splint, thereby accelerating the rotation speed of the cylindrical splint and reducing the contact time between the dust-free cloth and the longitudinal clamp when it is opened again, thereby reducing the wear caused by the mutual friction between the dust-free cloth and the longitudinal clamp. The longitudinal clamp clamps the dust-free cloth and also avoids the moving rollers 1 and 2 pulling the dust-free cloth when they move, thereby affecting the detection of the dust-free cloth by the horizontal pneumatic clamp. Therefore, the design also improves the detection accuracy.

[0013] Preferably, a control gear is provided on each of the two longitudinal clamping jaws, and the two control gears are respectively fixedly connected to one of the rotating shafts on the two longitudinal clamping jaws, and a tooth surface one is provided on the left control rod one and the right control rod one on the side of the moving roller one and the moving roller two close to the control gear, and the two tooth surfaces one are respectively engaged with the two control gears, the left connecting rod is fixedly connected with the left control rod two, and the right connecting rod is fixedly connected with the right control rod two, and a tooth surface two is provided on the left control rod two and the right control rod two, and the two tooth surfaces two are respectively engaged with the two control gears, the length of the tooth surface two is smaller than the length of the tooth surface one, and the tooth surface one and the tooth surface two are respectively located on both sides of the control gear.

[0014] It is easy to understand that the design is provided with control gears on both longitudinal clamping jaws, and tooth surface 1 is provided on moving roller 1 and moving roller 2 respectively. When moving roller 1 moves downward and moving roller 2 moves upward, the two tooth surfaces 1 will respectively push the control gears on the two longitudinal clamping jaws, and the control gears will then drive the rotating shaft to rotate so that the cylindrical clamping plate clamps the dust-free cloth. When moving roller 1 is about to move to the lowest point and moving roller 2 is about to move to the highest point, the two control gears will respectively engage with the two tooth surfaces 2. At this time, tooth surface 2 only needs to push the control gear slightly to make the cylindrical clamping plate lose pressure and then be bounced open by the torsion spring. When moving roller 1 moves from the lowest point to the highest point, and moving roller 2 moves from the highest point to the lowest point At this time, tooth surface two will re-engage with the control gear. At this time, since the length of tooth surface two is smaller than the length of tooth surface one, tooth surface two is not enough to control the cylindrical clamping plate to rotate to the angle of clamping the dust-free cloth. When moving roller one and moving roller two continue to move, the control gear will engage with tooth surface one again, and the control gear drives the cylindrical clamping plate to rotate in the opposite direction of the clamping direction. When the control gear moves away from tooth surface one, the cylindrical clamping plate will be pushed back to its original angle by the torsion spring, and will not affect the next rotation of the cylindrical clamping plate. This design enables the longitudinal clamping claw to clamp the dust-free cloth according to the movement of moving roller one and moving roller two, without the need to set up additional power, and the structure is simple and compact, which reduces the failure rate and subsequent maintenance costs.

[0015] Preferably, the longitudinal clamping claws located on one side of the left connecting rod are slidably connected with left pushing blocks 1 on both sides, the left pushing block 1 is slidably connected to the mounting seat, the two rotating shafts are rotatably connected to the left pushing block 1, the two sides of the left pushing block 1 are chamfered, the left control rod 2 on the movable roller 1 is fixedly connected with the left pushing block 2, one side of the left pushing block 2 is chamfered, the left pushing block 2 is in contact with the left pushing block 1, and a spring 2 is provided between the left pushing block 1 and the inner wall of the mounting seat.

[0016] It is easy to understand that when the moving rollers 1 and 2 move and drive the longitudinal clamps to clamp the dust-free cloth, the dust-free cloth is in a stretched state during the winding process. Therefore, when the longitudinal clamps clamp the dust-free cloth, the dust-free cloth is also in a stretched state. This time, when the transverse pneumatic clamp pulls the dust-free cloth for inspection, the dust-free cloth has a pulling force perpendicular to the pulling force of the transverse pneumatic clamp, which will affect the detection of the dust-free cloth by the transverse pneumatic clamp and affect the inspection accuracy. Therefore, this design sets a left push on both sides of the longitudinal clamp on the left connecting rod. Block one, when the moving roller one and the moving roller two move and drive the longitudinal clamping jaws to clamp the dust-free cloth, the moving roller one continues to move downward. At this time, the left pushing block two on the left control lever two will contact and squeeze the left pushing block one. At this time, the longitudinal clamping jaw on this side will move in the direction of the other longitudinal clamping jaw. At this time, the dust-free cloth that is stretched straight in the detection area will become loose due to the movement of the longitudinal clamping jaws. At this time, when the horizontal pneumatic clamping jaw starts to detect the dust-free cloth, it will not be affected by the additional pulling force. Therefore, this design improves the inspection accuracy of the cloth inspection machine.

[0017] Preferably, the longitudinal clamping claws located on one side of the right connecting rod are slidably connected with right pushing blocks 1 on both sides, and the right pushing block 1 is slidably connected to the mounting seat. The two rotating shafts are rotatably connected to the right pushing block 1, and both sides of the right pushing block 1 are chamfered. The right control rod 1 on the movable roller 2 is fixedly connected with the right pushing block 2, and one side of the right pushing block 2 is chamfered. The right pushing block 2 is in contact with the right pushing block 1, and a spring 3 is provided between the left pushing block 1 and the inner wall of the mounting seat.

[0018] It is easy to understand that conventional cloth inspection machines can wind up the dust-free cloth and test the tensile strength of the dust-free cloth. However, during the winding process, the dust-free cloth will be affected by dynamic factors such as real-time tension, winding speed, and equipment vibration. These factors may cause fluctuations in the test results. For example, uneven winding speed may cause the material to be unevenly stressed instantaneously, causing the tensile strength data to deviate from the true value. This design sets a right push block 1 on both sides of the longitudinal clamp on one side of the right connecting rod. When the transverse pneumatic clamp completes the inspection of the dust-free cloth, the moving roller 2 continues to move. At this time, the right push block 2 on the right control rod 1 will contact and squeeze the right push block 1 set on both sides of the longitudinal clamp on this side. At this time, the longitudinal clamp will move away from the other longitudinal clamp, thereby pulling the dust-free cloth located in a section of the inspection area. At this time, the tensile strength of the dust-free cloth along the winding direction can be measured, thereby avoiding the inspection accuracy of the dust-free cloth being affected during movement. Therefore, this design improves the inspection accuracy of the cloth inspection machine.

[0019] Preferably, induction switches are provided on both sides of the transverse pneumatic clamp, and the induction switches are electrically connected to the transverse pneumatic clamp. The induction switches are used to control the transverse pneumatic clamp to clamp the dust-free cloth, and the two induction switches are respectively in contact with the pressing blocks 2 on both sides. The height of the pressing block 2 on the left control rod 1 is higher than the height of the chamfer of the left push block 2, and the distance from the push block on the left control rod 1 to the pressing block 1 on one side is equal to the distance from the push block on the right control rod 1 to the pressing block 1 on one side, and the height of the pressing block 2 on the right control rod 1 is higher than the height of the chamfer of the right push block 2 on the right control rod 1.

[0020] It is easy to understand that this design makes it possible for the moving roller one to move from the highest point to the lowest point and the moving roller two to move from the lowest point to the highest point, and the moving roller one and the moving roller two will first drive the two longitudinal clamps to clamp the dust-free cloth. At this time, the moving roller one and the moving roller two continue to move, and then drive the longitudinal clamps near the unwinding roller to move to relax the dust-free cloth in the inspection area. At this time, the moving roller one and the moving roller two continue to move and drive the transverse pneumatic clamps on both sides of the dust-free cloth to start, and test the tensile strength of the dust-free cloth perpendicular to the winding direction. After the inspection is completed, the transverse pneumatic clamps release the dust-free cloth, and at this time, the moving roller one and the moving roller two continue to move, and then drive the longitudinal clamps near the winding roller to move and pull the dust-free cloth and test the tensile strength of the dust-free cloth along the winding direction. At this time, the inspection of a section of dust-free cloth is completed and repeated. Therefore, this design limits the height of the pressing block one and the pressing block two, so that the movement of the longitudinal clamps and the transverse start clamps can continue in sequence, and thus will not affect each other, thereby improving the reliability of the cloth inspection machine.

[0021] Preferably, when the two longitudinal clamping jaws clamp the dust-free cloth, the contact points between the two cylindrical clamping plates and the dust-free cloth are located on the side close to the winding roller.

[0022] It is easy to understand that since the cylindrical splint rotates eccentrically around the rotating shaft, the distance between the two cylindrical splints gradually decreases and the dust-free cloth is clamped. This design sets the rotation direction of the cylindrical splint when clamping, so that the contact position of the two cylindrical splints when clamping the dust-free cloth is close to one side of the winding roller, and when the moving roller one or the moving roller two respectively controls the movement of the two longitudinal clamps, the longitudinal clamps move toward the side close to the winding roller. Therefore, when the longitudinal clamps move, due to the friction between the cylindrical splint and the dust-free cloth, the longitudinal clamps will tend to rotate in the clamping direction in the process of moving and pulling the dust-free cloth, and the longitudinal clamps will clamp the dust-free cloth tighter and tighter in the process of moving and pulling the dust-free cloth, avoiding the dust-free cloth from sliding during the pulling process by the longitudinal clamps, which may cause wear of the dust-free cloth and affect the detection accuracy. Therefore, this design improves the detection accuracy of the longitudinal clamps when detecting the dust-free cloth.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention arranges transverse pneumatic clamps and longitudinal clamps on the cloth inspection machine. When the cloth inspection machine drives the dust-free cloth to reel up, the driving component drives the longitudinal clamps to clamp the dust-free cloth, so that one section of the dust-free cloth cannot move. At this time, the transverse pneumatic clamps start to clamp the dust-free cloth, and the driving component drives the transverse pneumatic clamps to move toward both sides of the dust-free cloth to test the dust-free cloth, so that the cloth inspection machine can test the tensile strength of the dust-free cloth perpendicular to the reeling direction. Therefore, this design improves the comprehensiveness of the cloth inspection machine's tensile strength test of the dust-free cloth, thereby improving the inspection quality and speed of the cloth inspection machine.

[0025] 2. The present invention arranges movable roller 1 and movable roller 2 inside the mounting base, so that the dust-free cloth located in the detection area will not continue to move, thereby improving the detection quality, and the winding roller and the unwinding roller can continue to wind up and release the dust-free cloth without stopping, and the dust-free cloth always remains flat during this process, thereby avoiding repeated starting and stopping of the motor during the detection process, and improving the detection accuracy and detection speed.

[0026] 3. The present invention provides control gears on both longitudinal clamping jaws, so that the longitudinal clamping jaws can clamp the dust-free cloth according to the movement of the moving roller 1 and the moving roller 2, without the need for additional power, and has a simple and compact structure, thereby reducing the failure rate and subsequent maintenance costs.

Induction switches are provided on both sides of the transverse pneumatic clamping jaw 6, and the induction switches are electrically connected to the transverse pneumatic clamping jaw 6. The induction switches The switch is used to control the transverse pneumatic clamping jaws 6 to clamp the dust-free cloth 5. The two induction switches are in contact with the pressing blocks 2 18 on both sides respectively. The height of the pressing block 2 18 on the left control rod 16 is higher than the height of the chamfer of the left push block 28, and the distance from the push block on the left control rod 16 to the pressing block 13 on one side is equal to the distance from the push block on the right control rod 17 to the pressing block 13 on one side. The height of the pressing block 2 18 on the right control rod 17 is higher than the height of the chamfer of the right push block 2 31 on the right control rod 17. When the two longitudinal clamping jaws 7 clamp the dust-free cloth 5, the contact point of the two cylindrical splints 20 with the dust-free cloth 5 is located on the side close to the winding roller 3.

[0042] See also Figures 1 to 10When the dust-free cloth 5 winding device with multi-roller synchronous tension control performs a winding inspection on the dust-free cloth 5, the unwinding roller 4 and the winding roller 3 are started, and the motor on the mounting base 1 is also started at the same time. At this time, the dust-free cloth 5 moves along the winding direction, and the moving roller 10 at the highest point moves toward the lowest point, and the moving roller 2 11 at the lowest point moves toward the highest point. At this time, the tooth surface 1 23 on the right control rod 17 and the tooth surface 1 23 on the left control rod 16 will respectively push the control gear 22 on the two longitudinal clamping jaws 7, and the control gear 22 will then drive the rotating shaft 19 to rotate, so that the cylindrical clamping plate 20 rotates eccentrically around the axis of the rotating shaft 19 until the dust-free cloth 5 is clamped. At this time, the moving roller 10 continues to move to pull the dust-free cloth 5 released by the unwinding roller 4, and the moving roller 10 will continue to move to pull the dust-free cloth 5 released by the unwinding roller 4, and the moving roller 11 will continue to move. The moving roller 11 continues to move, causing the dust-free cloth 5 pulled on the moving roller 11 to be wound onto the winding roller 3. At this time, after the moving roller 10 and the moving roller 11 continue to move a certain distance, the left pushing block 28 on the left control lever 2 24 will contact and squeeze the left pushing block 27, and the longitudinal clamping jaw 7 on this side will move in the direction of the other longitudinal clamping jaw 7, thereby causing the dust-free cloth 5 stretched straight in the detection area to become loose due to the movement of the longitudinal clamping jaw 7. The moving roller 10 and the moving roller 11 continue to move a certain distance. At this time, the pressing blocks 2 18 on the left control lever 1 16 and the right control lever 1 17 will respectively contact the pressing blocks 13 on both sides of the horizontal pneumatic clamping jaw 6, and the pressing blocks 2 18 will contact the induction switch on the pressing blocks 13, thereby The lateral pneumatic clamp 6 starts and clamps the dust-free cloth 5. At this time, the moving roller 10 and the moving roller 2 11 continue to move, and the pressing block 2 18 will continue to squeeze the pressing block 13 to make the lateral pneumatic clamps 6 on both sides squeeze the springs 12 on both sides respectively and move toward the two sides of the dust-free cloth 5. At this time, the dust-free cloth 5 is pulled by the lateral pneumatic clamps 6 on both sides. When the pressure sensors on the lateral pneumatic clamps 6 on both sides detect that the pressure reaches the tensile strength of the dust-free cloth 5 reaches 35N / 5cm, the clamping of the dust-free cloth 5 is released, and the moving roller 10 and the moving roller 2 11 continue to move the pressing block 2 18 away from the pressing block 13. The lateral pneumatic clamp 6 is reset by the push of the spring 12. At this time, the right push block 2 31 on the right control lever 17 will contact and squeeze the longitudinal clamp 7 on this side. A right pushing block 30 is provided on both sides, and the longitudinal clamping jaw 7 will move in the direction away from the other longitudinal clamping jaw 7, thereby pulling the dust-free cloth 5 located in a section of the inspection area. At this time, the moving roller 10 and the moving roller 2 11 continue to move, and the two control gears 22 will respectively engage with the two tooth surfaces 2 26. At this time, the tooth surface 2 26 only needs to slightly push the control gear 22 to make the cylindrical splint 20 lose pressure and then be bounced open by the torsion spring, thereby causing the two longitudinal clamping jaws 7 to release the dust-free cloth 5. When the moving roller 10 moves to the lowest point and the moving roller 2 11 moves to the highest point, the motor will drive the moving roller 10 to move from the lowest point to the highest point, and the moving roller 2 11 will move from the highest point to the lowest point. At this time, when the moving roller 10 moves to the highest point again,When the second moving roller 11 moves to the lowest position again, the dust-free cloth 5 originally located between the two longitudinal clamping jaws 7 will be rolled up and moved onto the second moving roller 11, and the dust-free cloth 5 originally located on the first moving roller 10 will be rolled up and moved between the two longitudinal clamping jaws 7. At this time, the above steps are repeated again to inspect the dust-free cloth 5 of this section again, and the above steps are repeated until all the dust-free cloths 5 are inspected.
