Description

Technical Field

[0001] This utility model relates to the field of membrane alignment technology, specifically to an alignment device for laser transparent membranes. Background Technology

[0002] Membrane alignment is a key technology in industrial production used to ensure that materials such as films and strips maintain the correct position and orientation during movement. It is widely used in packaging, printing, textiles, and optical film production. The core of membrane alignment is to use sensors to detect the edge or mark position of the material in real time, transmit the deviation signal to the controller, and then the actuator adjusts the position of the material to return it to the preset trajectory.

[0003] Currently, the correction devices used for laser transparent films generally consist of multiple guide rollers. The film is tractioned between the guide rollers. During correction, the horizontal position of the guide rollers is changed, causing the film to move horizontally, thereby achieving correction. This correction method has a good correction effect when the correction amount is small, but if the correction amount is large, the horizontal movement may cause the film to fold locally, which will lead to subsequent misalignment and exacerbate the correction error. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A correction device for laser transparent film includes a support platform. Guide rollers are installed on the left and right sides of the top of the support platform. The guide rollers on both sides are parallel to each other. Shaft seats are fixed on the support platform at both ends of the guide rollers. The two ends of the guide rollers are installed with the shaft seats at the corresponding positions. A correction plate is installed on the left side of the middle of the top of the support platform. A column is fixed at the middle of the bottom of the correction plate. A sleeve seat is fixed on the top of the support platform at the position corresponding to the column. The bottom of the column is fitted into the sleeve seat to form a limiting rotation support.

[0006] Furthermore, a worm gear is fixed on the column above the sleeve base, and a worm is meshed on the worm gear. Support seats are fixed on the top of the support platforms at both ends of the worm, and the two ends of the worm are installed with the corresponding support seats. A motor is installed on the top of the support platform corresponding to one end of the worm, and the output end of the motor is fixedly connected to the worm at the corresponding position. The worm gear drive structure is simple, and the worm gear has a self-locking feature, which can prevent abnormal rotation of the correction plate.

[0007] Furthermore, long strip seats are installed on the top of the support platform near both ends of the guide roller. A fixed seat is installed on top of each long strip seat, and an ultrasonic sensor is installed on top of each fixed seat. A limit groove is pre-set inside the support platform, and a slider is fixed to the bottom of the fixed seat corresponding to the limit groove. A lead screw is installed on the fixed seat corresponding to the limit groove. A knob is fixed to one end of the lead screw on the outside of the fixed seat. A hole is opened on the slider corresponding to the lead screw, and the lead screw passes through the hole and is threadedly connected to the slider. Since the laser transparent film is transparent, camera and infrared sensing methods are not suitable. Therefore, an ultrasonic sensing method adapted to the laser transparent film is selected, which can effectively detect the edge position of the film.

[0008] Furthermore, a smoothing plate is installed between the top straightening plate of the support platform and the right-side guide roller. The top height of the smoothing plate is the same as the top height of the straightening plate, while the top height of the straightening plate is higher than the top height of the guide roller. The smoothing plate is used to smooth the laser transparent film that is about to pass through the straightening plate, preventing wrinkles.

[0009] Furthermore, the smoothing plate is designed with an arc-shaped structure that convexes to the right in the middle and extends to the left at both ends. Multiple support columns are fixed to the bottom of the smoothing plate, and the bottoms of the support columns are fixed to corresponding support platforms. The arc-shaped structure matches the traction direction of the laser-transparent film, ensuring a smoothing effect on the film.

[0010] Furthermore, the top of the correction plate has multiple equally spaced recesses at both the front and rear ends. Guide wheels are installed inside the recesses, and fixing plates covering both ends of the guide wheels are fixed to the top of the recesses. The guide wheels are used to reduce the frictional resistance when the laser transparent film passes through the correction plate.

[0011] Furthermore, the guide wheels at the front and rear of the alignment plate are inclined at 45° to the centerline of the alignment plate, with the inclination direction being the left front and left rear directions of the alignment plate. This inclined arrangement can generate lateral force on the laser transparent film, thereby maintaining the smooth and flat surface of the laser transparent film.

[0012] Furthermore, a base is installed directly below the support platform, and a telescopic rod is installed at the center of the top of the base. The top of the telescopic rod is fixed to the support platform at the corresponding position. Sleeves are fixed at the four corners of the top of the base, and sleeve rods are fixed at the bottom of the support platform at the corresponding sleeve positions. The bottom part of the sleeve rod extends into the sleeve to form a sleeve connection. The support platform can be raised and lowered as needed to accommodate laser transparent films of different heights and tensions.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a rotating and tilting correction plate. When the laser transparent film passes through the correction plate, the tilted correction plate generates a lateral force, which causes the laser transparent film to undergo horizontal displacement as it passes through the correction plate, thereby achieving the effect of position correction. The greater the tilt of the correction plate, the greater the correction amplitude. The correction plate guides and corrects the laser transparent film rather than directly pulling and correcting it, making it less likely for the laser transparent film to fold locally.

[0015] 2. The curved smoothing plate in this utility model can smooth the laser transparent film, avoiding wrinkles on the laser transparent film from affecting the correction and position detection.

[0016] 3. The present invention provides guide wheels on the correction plate, which can reduce the frictional resistance to the laser transparent film. On the other hand, the tilt of the guide wheels can keep the laser transparent film smooth and flat when passing through the correction plate, further avoiding local folding.

[0017] 4. In this utility model, a telescopic rod is used to support the entire support platform. The tension of the laser transparent film can be adjusted by raising and lowering it, and the raising and lowering can also be adjusted according to the traction height of the laser transparent film.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a web-aligning device for laser transparent films, mainly addressing the problem that current web-aligning methods using transverse guide rollers can easily cause localized folding of the film when the web-aligning amount is large. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-6 Please provide a detailed explanation:

[0027] A correction device for laser transparent film includes a support platform 1. Guide rollers 2 are installed on the left and right sides of the top of the support platform 1. The guide rollers 2 on both sides are parallel to each other. Shaft seats 3 are fixed on the support platform 1 at both ends of the guide rollers 2. The two ends of the guide rollers 2 are installed with the shaft seats 3 at the corresponding positions. A correction plate 4 is installed on the left side of the middle of the top of the support platform 1. A column 5 is fixed at the middle of the bottom of the correction plate 4. A sleeve seat 6 is fixed on the top of the support platform 1 at the position corresponding to the column 5. The bottom of the column 5 is fitted into the sleeve seat 6 to form a limiting rotation support.

[0028] A worm gear 7 is fixed on the column 5 above the sleeve base 6. A worm 8 is meshed on the worm gear 7. Support seats 9 are fixed on the top of the support platform 1 at both ends of the worm 8. The two ends of the worm 8 are installed with the support seats 9 at the corresponding positions. A motor 10 is installed on the top of the support platform 1 at one end of the worm 8. The output end of the motor 10 is fixedly connected to the worm 8 at the corresponding position. The motor 10 is a servo motor.

[0029] In use, the laser transparent film is pulled from right to left above the support platform 1, so that the laser transparent film falls simultaneously on the guide rollers 2 and the correction plate 4 on both sides of the support platform 1 to form support. When the laser transparent film is pulled, the friction between it and the guide rollers 2 drives the guide rollers 2 to rotate, thereby guiding the traction of the laser transparent film. When correction is needed, the control motor 10 works, and the meshing relationship between the worm gear 7 and the worm 8 ultimately drives the correction plate 4 to rotate horizontally, so that the correction plate 4 and the guide rollers 2 are tilted. When the laser transparent film passes the tilted correction plate 4, a lateral force is generated, which causes the laser transparent film to move in the tilt direction. Finally, when the laser transparent film is pulled out from the left side of the support platform 1, it moves to a horizontal position, thus achieving the correction effect.

[0030] In some embodiments, a long strip seat 11 is installed on the top of the support platform 1 near both ends of the guide roller 2. A fixed seat 12 is installed on the top of the long strip seat 11. An ultrasonic sensor 17 is installed on the top of the fixed seat 12. A limit groove 16 is preset in the support platform 1. A slider 13 is fixed at the bottom of the fixed seat 12 corresponding to the position of the limit groove 16. A lead screw 14 is installed on the fixed seat 12 corresponding to the position of the limit groove 16. A knob 15 is fixed at one end of the lead screw 14 on the outside of the fixed seat 12. A hole is opened on the slider 13 corresponding to the position of the lead screw 14. The lead screw 14 passes through the hole and is threadedly connected to the slider 13.

[0031] After the laser transparent film is pulled, the position of the ultrasonic sensor 17 is adjusted so that it can be aligned with the preset edge position of the laser transparent film. The right side of the support platform 1 is the input position and the left side is the output position. By comparing the left and right positions, the amount of correction can be determined. When adjusting the ultrasonic sensor 17, the knob 15 is turned to drive the lead screw 14 to rotate. Utilizing the threaded connection between the lead screw 14 and the slider 13, under the limit of the limiting groove 16, the slider 13 and the fixed seat 12 move along the lead screw 14, thereby adjusting the position of the ultrasonic sensor 17. The cooperation between the lead screw 14 and the slider 13 can perform edge detection on laser transparent films of different widths.

[0032] In some embodiments, a smoothing plate 18 is installed between the top correction plate 4 of the support platform 1 and the right guide roller 2. The top height of the smoothing plate 18 is the same as the top height of the correction plate 4, and the top height of the correction plate 4 is higher than the top height of the guide roller 2. The smoothing plate 18 is arranged in an arc-shaped structure with the middle convex to the right and both ends extending forward to the left. Multiple support columns 19 are fixed at the bottom of the smoothing plate 18, and the bottom of the support columns 19 is fixed to the support platform 1 at the corresponding position.

[0033] The smoothing plate 18 is used to smooth the laser transparent film to avoid wrinkles. At the same time, the arc-shaped structure, combined with the traction direction of the laser transparent film from right to left, generates stress on the laser transparent film from the middle to both sides of the width. This prevents the laser transparent film from forming local folds on the correction plate 4 when it passes through the correction plate 4, especially when the correction plate 4 rotates for correction.

[0034] In some embodiments, the top of the correction plate 4 has multiple equally spaced recesses 25 at both the front and rear ends. Guide wheels 24 are installed in the recesses 25. Fixing plates 26 covering both ends of the guide wheels 24 are fixed on the top of the recesses 25. The guide wheels 24 at the front and rear of the correction plate 4 are inclined at 45° to the center line of the correction plate 4. The inclination direction is the left front and left rear direction of the correction plate 4.

[0035] The guide roller 24 contacts the laser transparent film to ensure that the laser transparent film can pass smoothly through the correction plate 4. At the same time, the inclined guide roller 24 can generate a lateral force on the laser transparent film from the middle to both sides of the width to maintain the smoothness of the laser transparent film surface and further avoid folding.

[0036] In some embodiments, a base 20 is installed directly below the support platform 1, and a telescopic rod 21 is installed at the middle of the top of the base 20. The top of the telescopic rod 21 is fixed to the support platform 1 at the corresponding position. The telescopic rod 21 can be any one of hydraulic, pneumatic and electric telescopic rods. In this embodiment, the telescopic rod 21 is an electric telescopic rod. Sleeves 22 are fixed at the four corners of the top of the base 20, and sleeve rods 23 are fixed at the bottom of the support platform 1 at the corresponding positions of the sleeves 22. The bottom part of the sleeve rod 23 extends into the sleeve 22 to form a sleeve connection.

[0037] The telescopic rod 21 can drive the entire support platform 1 to rise and fall, thereby adjusting the tension of the traction laser transparent film to prevent it from being too tight or too loose. It can also be adjusted according to the traction height of the laser transparent film on site to ensure that the guide roller 2, the correction plate 4, and the smoothing plate 18 can contact the laser transparent film, thus ensuring that their respective functions are normal.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
