A deviation rectifying mechanism and a laminating machine

Abstract

The application provides a deviation rectifying mechanism and a laminating machine. The deviation rectifying mechanism comprises a rack, a sliding seat, a feeding roller, a feeding roll, a feeding driving unit, two position detectors and a deviation rectifying driving unit. The feeding driving unit drives the feeding roller to rotate, and then drives the feeding roll to rotate to realize unwinding of the film strip. The unwound film strip can pass through the area between the two position detectors, and the position of the film strip can be monitored by the two position detectors. When the two position detectors monitor that the position of the film strip deviates, the sliding seat is driven by the deviation rectifying driving unit to slide on the rack, and then the position of the feeding roll can be adjusted correspondingly until the film strip is in the correct position. In this way, the deviation rectifying mechanism can monitor the position of the film strip, adjust the position of the feeding roll, ensure the feeding accuracy of the film strip, and improve the product quality of the laminating machine.

Description

Technical Field

[0001] This application belongs to the field of lamination technology, and more specifically, relates to a correction mechanism and a lamination machine using the correction mechanism. Background Technology

[0002] The film feeding mechanism of the laminator is used to unwind the film strip. Typically, a drive module drives the feeding roller to rotate, which in turn rotates the unwinding roll to unwind the film strip. The unwound film strip is then transferred to the lamination station, where it is cut to achieve the lamination process. The feeding accuracy of the film strip determines the quality of the final laminated product.

[0003] Since the unwinding roll is mounted on the feeding roller, it inevitably experiences positional shifts during rotation. This leads to positional deviations in the film strip unwound from the unwinding roll during transport, affecting the accuracy of subsequent film cutting and lamination, and ultimately impacting the quality of the laminated product. Therefore, it is urgent to design a web-correcting mechanism to ensure the unwinding accuracy of the film strip, thereby ensuring the yield of laminated products. Utility Model Content

[0004] The purpose of this application is to provide a correction mechanism and a laminating machine to solve the problem in the related art where the film strip being unwound from the feed roll will shift in position, affecting the quality of the laminated product.

[0037] Please see Figure 1 and Figure 2 The web-correcting mechanism provided in this application embodiment will now be described. This web-correcting mechanism includes a frame 1, a sliding seat 2, a feeding roller 3, a feeding roll 4, a feeding drive unit 5, two position detectors 6, and a web-correcting drive unit 7. The sliding seat 2 is slidably mounted on the frame 1; the feeding roller 3 is rotatably mounted on the sliding seat 2; the feeding roll 4 is sleeved and mounted on the feeding roller 3, and a film strip is wound on the feeding roll 4 for unwinding the film strip. The feeding drive unit 5 is mounted on the sliding seat 2, and its output end is connected to the feeding roller 3. The feeding drive unit 5 drives the feeding roller 3 to rotate, which in turn drives the feeding roll 4 to rotate, thereby unwinding the film strip. An area is formed between the two position detectors 6 for the film strip to pass through; that is, the film strip unwound by the feeding roll 4 can pass through the area between the two position detectors 6, thus enabling real-time monitoring of the film strip's position. The web guiding drive unit 7 is mounted on the frame 1 and connected to the sliding seat 2. The web guiding drive unit 7 drives the sliding seat 2 to reciprocate on the frame 1. In this structure, the feeding drive unit 5 drives the feeding roller 3 to rotate, which in turn drives the unwinding roll 4 to rotate, thus unwinding the film strip. The unwound film strip passes through the area between the two position detectors 6, which monitor the position of the film strip. When the two position detectors 6 detect a positional shift in the film strip, the web guiding drive unit 7 drives the sliding seat 2 to slide on the frame 1, thereby adjusting the position of the unwinding roll 4 until the film strip is in the correct position. In this way, the web guiding mechanism can monitor the position of the film strip and adjust the position of the unwinding roll 4, ensuring the accuracy of film strip feeding and improving the product quality of the laminated film.

[0038] In one embodiment, see Figure 2As a specific embodiment of the correction mechanism provided in this application, the correction mechanism further includes a support base 8 and a support moving unit 9. Two position detectors 6 are respectively mounted on the support base 8, and the support moving unit 9 is mounted on the frame 1. The output end of the support moving unit 9 is connected to the support base 8. The support moving unit 9 can be a cylinder / electric cylinder transmission mechanism, a lead screw transmission mechanism, a linear motor, etc., and is not limited to any particular type. In this structure, the support moving unit 9 can drive the two position detectors 6 to reciprocate, thereby adjusting the positions of the two position detectors 6. Each position detector 6 can be an ultrasonic detector; the reciprocating direction of the two position detectors 6 is the axial direction of the feeding roller 3.

[0039] Optionally, a finger cylinder is mounted on the support base 8, and two position detectors 6 are respectively mounted on the two output ends of the finger cylinder. In this structure, the two position detectors 6 can be controlled to move closer or further apart through the finger cylinder, thereby adjusting the distance between the two position detectors 6, which can be adapted to membrane tapes of different thicknesses.

[0040] In one embodiment, see Figure 2 As a specific embodiment of the correction mechanism provided in this application, two displacement sensors 91 are installed at intervals on the support moving unit 9, and a sensing plate 81 is installed on the support base 8, with the sensing plate 81 positioned between the two displacement sensors 91. The two displacement sensors 91 are spaced apart along the axial direction of the feeding roller 3. This structure, through the sensing cooperation between the sensing plate 81 and the two displacement sensors 91, can limit the reciprocating stroke of the two position detectors 6.

[0041] In one embodiment, see Figure 1 and Figure 3 As a specific embodiment of the correction mechanism provided in this application, the correction drive unit 7 includes a correction seat 71, a correction power seat 72, and a correction drive component 73. The correction power seat 72 is mounted on the sliding seat 2, and the correction drive component 73 is mounted on the correction seat 71. The correction seat 71 is hingedly mounted on the frame 1, and the output end of the correction drive component 73 is hingedly mounted on the correction power seat 72. The correction drive component 73 can be a cylinder, an electric cylinder, etc., and is not limited to any particular type. In this structure, the correction drive component 73 can drive the sliding seat 2 to reciprocate on the frame 1 via the correction power seat 72. By hingedly mounting the correction seat 71 on the frame 1 and hingedly mounting the output end of the correction drive component 73 on the correction power seat 72, a floating installation of the correction drive unit 7 is achieved, preventing hard contact and hard collisions caused by rigid installation.

[0042] In one embodiment, see Figure 1As a specific embodiment of the correction mechanism provided in this application, the correction mechanism further includes a guide roller 10 rotatably mounted on the sliding seat 2, the guide roller 10 being arranged parallel to and spaced apart from the feeding roller 3. This structure allows the guide roller 10 to receive the film strip released from the unloading roll 4 and guide the film strip, thus preventing positional deviation of the film strip during transport.

[0043] In one embodiment, see Figure 4 In one specific embodiment of the correction mechanism provided in this application, a side-moving seat 21 is mounted on the sliding seat 2, and the guide roller 10 is rotatably mounted on the side-moving seat 21; a first guide rail 11 is mounted on the frame 1, and a first slider 12 is mounted on the first guide rail 11, with the side-moving seat 21 mounted on the first slider 12. The first guide rail 11 extends along the axial direction of the guide roller 10. With this structure, when the correction drive unit 7 drives the sliding seat 2 to move on the frame 1, the feeding roller 3 and the unloading roll 4 move synchronously, and the guide roller 10 moves synchronously with them, preventing positional shift of the film belt between the unloading roll 4 and the guide roller 10.

[0044] In one embodiment, as a specific implementation of the correction mechanism provided in this application, the side moving seat 21 and the sliding seat 2 are detachably connected. Optionally, the side moving seat 21 can be connected to the sliding seat 2 by fasteners such as screws; it can also be connected by snap-fit ​​connections, etc. This structure, by setting the side moving seat 21 and the sliding seat 2 to be detachably connected, facilitates the disassembly of the side moving seat 21, and thus facilitates the disassembly and maintenance of the guide roller 10.

[0045] In one embodiment, see Figure 1 As a specific embodiment of the correction mechanism provided in this application, the feeding drive unit 5 includes a driven wheel 51, a feeding drive component 52, a drive wheel 53, and a feeding belt 54. The driven wheel 51 can be installed on one end of the feeding roller 3, and the other end of the feeding roller 3 can be rotatably installed on the frame 1. The feeding drive component 52 is installed on the sliding seat 2. The feeding drive component 52 can be a motor. The drive wheel 53 is installed on the output end of the feeding drive component 52, that is, on the output shaft of the motor. The feeding belt 54 connects the drive wheel 53 and the driven wheel 51. In this structure, the drive wheel 53 is driven to rotate by the feeding drive component 52, and then the feeding roller 3 can be driven to rotate by the feeding belt 54 and the driven wheel 51, thus realizing the film tape feeding operation of the unloading roll 4.

[0046] Optionally, the driving wheel 53 has a circumferential annular array of main anti-slip teeth, and the driven wheel 51 has a circumferential annular array of driven anti-slip teeth. The feeding belt 54 has feeding convex teeth that mesh with the main and driven anti-slip teeth respectively. This structure, through the meshing of the feeding convex teeth with the main and driven anti-slip teeth respectively, can prevent the feeding belt 54 from slipping during rotation, thereby improving the transmission efficiency of the feeding drive unit 5.

[0047] In some embodiments, the feeding drive unit 5 may also be a drive motor directly connected to the feeding roller 3, or a combination of a drive motor and a gear set, that is, the drive motor drives the feeding roller 3 to rotate through the gear set, which is not the only limitation.

[0048] In one embodiment, see Figure 1 As a specific embodiment of the correction mechanism provided in this application, a second guide rail 13 is installed on the frame 1, and the second guide rail 13 extends along the axial direction of the feeding roller 3; a second slider 14 is installed on the second guide rail 13, and the sliding seat 2 is installed on the second slider 14. This structure, through the positioning cooperation between the second slider 14 and the second guide rail 13, can improve the stability of the sliding seat 2 reciprocating on the frame 1.

[0049] This application embodiment also provides a laminating machine, including the correction mechanism provided in any of the above embodiments. In this structure, the feeding roller 3 is driven to rotate by the feeding drive unit 5, which in turn drives the unwinding roll 4 to rotate, thus unwinding the film strip. The unwound film strip can pass through the area between two position detectors 6, which monitor the position of the film strip. When the two position detectors 6 detect a positional shift in the film strip, the correction drive unit 7 drives the sliding seat 2 to slide on the frame 1, thereby adjusting the position of the unwinding roll 4 accordingly until the film strip is in the correct position. In this way, the correction mechanism can monitor the position of the film strip and adjust the position of the unwinding roll 4, ensuring the accuracy of film strip feeding. The laminating machine using this correction mechanism produces products with good quality and a high yield rate.

[0050] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
