The device includes a gantry support, a drive module located in the middle of the gantry support, and a film material winding mechanism located at the lower front end of the drive module. The film material winding mechanism includes a mounting plate, and a winding mechanism is mounted on the bottom of the mounting plate via a mounting bracket. This invention goes beyond simple winding; it achieves a seamless process from input film material to output tube.

Description

Technical Field

[0001] This invention relates to the field of flexible material processing equipment technology, specifically to a film material winding device for forming a tube and its usage method. Background Technology

[0002] In industries such as food packaging, medical devices, and electronic 3C tubing, it is often necessary to wind strips of plastic film into tubular shapes.

[0003] Current membrane winding mechanisms on the market can no longer meet the latest and higher market requirements: 1. Poor winding accuracy and tightness: During traditional equipment winding, gaps or air bubbles are easily generated between film layers, resulting in loose and loose tubes, and misalignment of the membrane shaft ends, affecting the quality of the finished product; 2. Lack of automation or low efficiency: Many mechanisms require manual intervention for film threading, roll changing, or adjustment, resulting in low automation and affecting production efficiency; 3. Single function: Most winding mechanisms only complete the winding. If simultaneous sealing and welding is required, multiple complex machines need to be connected in series, making the system large; 4. Membrane surface protection: During winding or conveying, guide rollers may come into contact with and damage the functional surfaces of the membrane, affecting product performance. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0007] Furthermore, the winding mechanism includes two mounting brackets, which are respectively bolted to the bottom ends of the mounting plate. A bearing mounting seat is bolted to the middle of the side of each mounting bracket that is close to the other. A second pulley is sleeved on the outer side of the bearing mounting seat. A connecting seat is bolted to the side of the second pulley away from the bearing mounting seat. A clamping cylinder is bolted to the side of the connecting seat away from the second pulley. Connecting plates are fixedly connected to the upper and lower output ends of the clamping cylinder. Connecting arms are bolted to the other ends of the two connecting plates. Rubber-coated grippers are bolted to the inner side of the end of each connecting arm away from the corresponding connecting plate. A mandrel is clamped between the two rubber-coated grippers, and film material is wound around the outer side of the mandrel.

[0008] Furthermore, a servo motor is bolted to the lower right end of the mounting plate via an inclined plate. The output end of the servo motor is connected to a torque sensor via a coupling. The output end of the torque sensor is connected to a drive shaft passing through two mounting brackets via a coupling. Both ends of the drive shaft are fitted with first pulleys, and the first and second pulleys are connected by a belt drive. Both ends of the film material are integrally formed with handles inside the corresponding rubber-coated grippers.

[0009] Furthermore, the solid winding mechanism includes a second slide cylinder, which is obliquely mounted on the back left end of the mounting plate via a mounting plate. The output end of the second slide cylinder is bolted to a first U-shaped frame, and the interior of the first U-shaped frame is rotatably connected to a first rubber-coated roller via a rotating shaft. The bottom end of the first rubber-coated roller contacts the upper rear end of the mandrel.

[0010] Furthermore, the softening mechanism is located to the left of the pressing and spot welding mechanism. The softening mechanism includes a second Y-axis lead screw module bolted to the top left end of the mounting plate. A mounting bracket is bolted to the sliding end of the top of the second Y-axis lead screw module. A first slide cylinder is bolted to the front left end of the mounting bracket via a side plate. A hot air gun is mounted on the side of the output end of the first slide cylinder via a clamping seat. The air outlet end of the hot air gun is positioned opposite to the film material.

[0011] Furthermore, the pressing spot welding mechanism includes a third slide cylinder, which is obliquely bolted to the right end of the mounting frame via a tripod. A fixing plate is bolted to the front of the output end of the third slide cylinder. A spot welding cylinder is bolted to one side of the top of the fixing plate via a first connecting block. A spot welding mechanism is bolted to the output end of the spot welding cylinder. A second U-shaped frame is bolted to the bottom end of the fixing plate. A second rubber-coating roller, which is opposite to the first rubber-coating roller, is rotatably connected inside the second U-shaped frame via a rotating shaft.

[0012] Furthermore, a U-shaped support frame is bolted between the bottoms of the two mounting brackets. A correction sensor is bolted to the middle of the support frame, and the detection end of the correction sensor is directly opposite the edge of the tubular film material. A hot air gun controller electrically connected to the hot air gun is fixedly installed at the top left end of the gantry bracket. A mounting base is bolted to the top of the mounting plate and to the right of the second Y-axis lead screw module. A film material initial positioning CCD is fixedly installed at the front end of the mounting base.

[0013] Furthermore, the tail material clamping mechanism includes a vertical plate bolted to the bottom of the support frame. A fourth slide cylinder is bolted to the front of the vertical plate. An extension plate extending to the right is bolted to the output end of the fourth slide cylinder. Two symmetrically distributed linear bearings are fixedly installed inside the extension end of the extension plate. Locating pins are slidably fitted inside the two linear bearings. The top of the locating pin passes through the linear bearing and extends upward to be bolted to a clamping plate. The clamping plate is located below and in contact with the second rubber-coated roller. A spring is sleeved on the outside of the locating pin between the extension plate and the clamping plate.

[0014] In addition, the present invention also provides a method of using the film material winding into a tube device: Includes the following steps: Step 1: First, install the mandrel in the left and right mandrel clamps. Then, the external controller controls the movement of the Z-axis lead screw module and the first Y-axis lead screw module to adjust the position of the film material winding mechanism to facilitate subsequent winding. Step 2: Control the extension of the clamping cylinder through the external controller to open the rubber-coating jaws, and then extend the fourth slide cylinder and drive the clamping plate to move upward to the highest point; Step 3: Next, the strip-shaped film material is fed into the lower part of the mandrel through the top of the clamping plate. At this time, the pull handle of the film material is located inside the rubber-coated clamping claw. Then, the external controller controls the clamping cylinder to reset and clamps the pull handle of the film material and the mandrel together through the rubber-coated clamping claw to form a preliminary positioning. Then, the external controller controls the initial positioning CCD of the film material to work and detect the position of the film material. Step 4: When the initial positioning is accurate, the external controller controls the second Y-axis lead screw module to work and drives the softening mechanism and the pressing spot welding mechanism to move to the right through the mounting bracket until the second coating roller moves above the clamping plate. At the same time, the third slide cylinder extends and drives the second coating roller to move downward through the second U-shaped frame and contact the film material. Then, the external controller controls the servo motor to work. The servo motor drives the transmission shaft to rotate counterclockwise through the coupling and torque sensor. The transmission shaft drives the two first pulleys on it to rotate. The first pulley drives the second pulley to rotate through the belt. The second pulley drives the connecting seat, clamping cylinder, connecting plate, connecting arm, coating jaw, mandrel jaw and mandrel to rotate counterclockwise one revolution. At the same time, under the clamping of the second coating roller and the clamping plate, the film material is kept in a taut state during the winding process, so that the film material is tightly wound on the mandrel and avoids air bubbles during the winding process. At the same time, the servo motor stops, the second slide cylinder extends and drives the first coating roller to approach and contact the film material that has been wound once through the first U-shaped frame. Step 5: After the first rubber-coating roller in Step 4 presses the film material onto the mandrel, adjust the outlet of the hot air gun to align with the film material and blow hot air to soften it. Simultaneously, the servo motor starts, causing the mandrel to rotate and wind the film material. During the winding process, the cooperation of the first rubber-coating roller, the second rubber-coating roller, and the pressing plate makes the winding tighter and free of air bubbles. Finally, the spot welding mechanism spots welds and seals the ends of the tube at multiple locations. During the winding process, the correction sensor checks the data of the film roll offset and uploads it to the external controller. The external controller controls the second, third, and fourth slide cylinders to cooperate in correcting the left and right positions of the film material. At the same time, the servo motor can output constant torque during the tube winding process to ensure consistent tension at any position of the tube. In conjunction with the torque sensor, the tension data of the tube winding process can be monitored and fed back to confirm whether the winding tension is qualified.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention is no longer a simple winding process, but rather a one-stop process from input film material to output tube; compared with static pressing mechanisms, this invention adopts flexible pressing film material, hot air softening, high-precision sensor correction, constant torque control of servo motor, and torque sensor feedback, which solves the problem of uneven pressure caused by changes in tube diameter during winding, ensuring tight interlayer bonding, no air bubbles, uniform thickness, and neat ends of the tube; at the same time, it can be adjusted according to product size and is compatible with film materials of various widths; the degree of automation is high, reducing manual intervention.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-10A membrane material winding device includes a gantry support 1, a drive module 2 in the middle of the gantry support 1, and a membrane material winding mechanism 3 at the lower front end of the drive module 2.

The strip-shaped membrane material 515 and the mandrel 514 are clamped by the winding mechanism 5, and the membrane material 515 can be spirally wound on the rotatable mandrel 514. After correction, tension control, and softening of both sides by hot air, the membrane material 515 is neatly overlapped and forms a continuous tubular material. Subsequently, the ends of the tube are spot welded and sealed at multiple locations.

[0022] Furthermore, the drive module 2 includes a first Y-axis lead screw module 202 bolted to the center of the front of the gantry bracket 1. A Z-axis lead screw module 201 is bolted to the sliding end of the front of the first Y-axis lead screw module 202. The sliding end of the Z-axis lead screw module 201 is fixedly connected to the mounting plate 301 through the lifting plate 203. The Z-axis lead screw module 201 and the first Y-axis lead screw module 202 provide Z and Y direction drive for the film material winding into tube mechanism 3.

[0023] Furthermore, the winding mechanism 5 includes two mounting brackets 302, which are respectively bolted to the bottom ends of the mounting plate 301. Bearing fixing seats 505 are bolted to the middle of the sides of the two mounting brackets 302 that are close to each other. A second pulley 506 is sleeved on the outer side of the bearing fixing seat 505. A connecting seat 508 is bolted to the side of the second pulley 506 away from the bearing fixing seat 505. A clamping cylinder 509 is bolted to the side of the connecting seat 508 away from the second pulley 506. Connecting plates 510 are fixedly connected to the upper and lower output ends of the clamping cylinder 509. Connecting arms 511 are bolted to the other ends of the two connecting plates 510. The ends of the two connecting arms 511 away from the corresponding connecting plates 510... Both sides are bolted with rubber-coated grippers 512, and a mandrel 514 is held between two rubber-coated grippers 512. Film material 515 is wound around the outside of the mandrel 514. The mandrel grippers 513 on the left and right sides can hold the mandrel 514. The gripping cylinder 509 can drive the rubber-coated grippers 512 to move through the connecting plate 510 and the connecting arm 511, so that the opposite rubber-coated grippers 512 can hold the film material 515 and the mandrel 514. At the same time, the second pulley 506 can drive the gripping cylinder 509 to rotate, so that the film material 515 can be wound onto the mandrel 514. The rubber-coated grippers 512 complete the initial gripping of the film material 515 through the gripping handle 516 to avoid damage to the film material 515.

[0024] Furthermore, a servo motor 501 is bolted to the lower right end of the mounting plate 301 via an inclined plate. The output end of the servo motor 501 is connected to a torque sensor 503 via a coupling. The output end of the torque sensor 503 is connected to a drive shaft 502 that passes through the two mounting brackets 302 via a coupling. Both ends of the drive shaft 502 are fitted with first pulleys 504. The first pulleys 504 and the second pulleys 506 are connected by a belt 507. Both ends of the film material 515 are integrally formed with handles 516 inside the corresponding rubber-coated grippers 512. The servo motor 501 drives the transmission shaft 502 to rotate counterclockwise via a coupling and a torque sensor 503. The transmission shaft 502 drives the two first pulleys 504 on it to rotate. The first pulleys 504 drive the second pulley 506 to rotate via a belt 507, thereby driving the clamping cylinder 509 to rotate. The servo motor 501 controls the tube winding process with constant torque. The servo motor 501 can output constant torque to ensure that the tension is consistent at any position of the tube winding. The torque sensor 503 provides feedback: it monitors and feeds back the tension data during the tube winding process, and uses this data to confirm whether the winding tension is qualified.

[0025] Furthermore, the solid winding mechanism 6 includes a second slide cylinder 602, which is obliquely mounted on the left side of the back of the mounting plate 301 via a mounting plate 601. The output end of the second slide cylinder 602 is bolted to a first U-shaped frame 603. The first U-shaped frame 603 is rotatably connected to a first rubber-coated roller 604 via a rotating shaft. The bottom end of the first rubber-coated roller 604 contacts the upper rear side of the mandrel 514. The second slide cylinder 602 extends and drives the first rubber-coated roller 604 to approach and contact the film material 515 that has been wound once through the first U-shaped frame 603. The first rubber-coated roller 604 can tightly adhere the film material 515 to the mandrel 514, ensuring the tightness of the winding and reducing the generation of air bubbles.

[0026] Furthermore, the softening mechanism 4 is located to the left of the pressing and spot welding mechanism 7. The softening mechanism 4 includes a second Y-axis lead screw module 401 bolted to the top left end of the mounting plate 301. A mounting bracket 402 is bolted to the sliding end of the top of the second Y-axis lead screw module 401. A first slide cylinder 403 is bolted to the front left end of the mounting bracket 402 through a side plate. A hot air gun 405 is mounted on the side of the output end of the first slide cylinder 403 through a clamping seat 404. The air outlet end of the hot air gun 405 is positioned opposite to the film material 515. The position of the hot air gun 405 can be adjusted by the second Y-axis lead screw module 401, so that the hot air gun 405 softens both sides of the film material 515, achieving neat overlap and forming a continuous tubular structure.

[0027] Furthermore, the clamping spot welding mechanism 7 includes a third slide cylinder 701, which is obliquely bolted to the right end of the mounting bracket 402 via a tripod. A fixing plate 707 is bolted to the front of the output end of the third slide cylinder 701. A spot welding cylinder 703 is bolted to one side of the top of the fixing plate 707 via a first connecting block 702. A spot welding mechanism 704 is bolted to the output end of the spot welding cylinder 703. A second U-shaped frame 705 is bolted to the bottom end of the fixing plate 707.

The second coating roller 706 is provided; the second coating roller 706 is located below the spot welding mechanism 704, which facilitates spot welding after pressing the film material 515; the third slide cylinder 701 extends and drives the second coating roller 706 to move downward through the second U-shaped frame 705 and contact the film material 515, while the spot welding cylinder 703 moves accordingly. The extension and retraction of the spot welding cylinder 703 can adjust the distance between the spot welding mechanism 704 and the film material 515 to facilitate spot welding of the tail end of the film material 515 wound into a tube; the spot welding mechanism 704 adopts a brass heating spot welding method.

[0028] Furthermore, a U-shaped support frame 8 is bolted between the bottoms of the two mounting brackets 302. A correction sensor 801 is bolted to the middle of the support frame 8. The detection end of the correction sensor 801 is directly opposite the edge of the tubular film material 515. A hot air gun controller 12, which is electrically connected to the hot air gun 405, is fixedly installed at the top left end of the gantry bracket 1. A mounting base 10 is bolted to the top of the mounting plate 301 and to the right of the second Y-axis lead screw module 401. A film material initial positioning CCD 11 is fixedly installed at the front end of the mounting base 10. During the winding process, the correction sensor 801 checks the data of the film roll offset and uploads it to the external controller. The external controller controls the second slide cylinder 602, the third slide cylinder 701, and the fourth slide cylinder 902 to cooperate in correcting the position of the left and right film materials. The external controller controls the film material initial positioning CCD 11 to work and detect the position of the film material 515.

[0029] Furthermore, the tail material clamping mechanism 9 includes a vertical plate 901 bolted to the bottom of the support frame 8. A fourth slide cylinder 902 is bolted to the front of the vertical plate 901. An extension plate 903 extending to the right is bolted to the output end of the fourth slide cylinder 902. Two symmetrically distributed linear bearings 904 are fixedly installed inside the extension end of the extension plate 903. Locating pins are slidably fitted inside the two linear bearings 904. The top of the locating pins passes through the linear bearings 904 and extends upwards to be bolted to a clamping plate 9. 06. The clamping plate 906 is located below and in contact with the second coating roller 706. A spring 905 is sleeved on the outside of the positioning pin and between the extension plate 903 and the clamping plate 906. The fourth slide cylinder 902 extends and drives the clamping plate 906 to move upward to the highest point. The clamping plate 906, together with the first coating roller 604 and the second coating roller 706, can tighten the film material 515 during the winding process, making the winding tighter and free of air bubbles, while protecting the film material 515.

[0030] Working principle: The mandrel 514 is pre-installed in the left and right mandrel clamps 513. Then, the external controller controls the movement of the Z-axis lead screw module 201 and the first Y-axis lead screw module 202 to adjust the position of the film winding mechanism 3 for subsequent winding. The external controller controls the extension of the clamping cylinder 509, causing the coating clamps 512 to open. Then, the fourth slide cylinder 902 extends and drives the clamping plate 906 to move upward to the highest point. Next, the strip-shaped film 515 is fed into the space below the mandrel 514 through the top of the clamping plate 906. At this time, the pull handle 516 of the film 515 is located inside the coating clamps 512. Then, the external controller controls the clamping cylinder 509 to reset and uses the coating clamps 512 to pull the pull handle 516 of the film 515. Together with the mandrel 514, the film material is initially positioned. Then, the external controller controls the initial positioning CCD 11 of the film material to work and detect the position of the film material 515. When the initial positioning is accurate, the external controller controls the second Y-axis lead screw module 401 to work and drives the softening mechanism 4 and the pressing spot welding mechanism 7 to move to the right through the mounting bracket 402 until the second coating roller 706 moves above the abutment plate 906. At the same time, the third slide cylinder 701 extends and drives the second coating roller 706 to move downward through the second U-shaped frame 705 and contact the film material 515. Then, the external controller controls the servo motor 501 to work. The servo motor 501 drives the transmission shaft 502 to rotate counterclockwise through the coupling and torque sensor 503. The transmission shaft 502 drives the two rollers on it to rotate counterclockwise. The first pulley 504 rotates, driving the second pulley 506 to rotate via belt 507. The second pulley 506 drives the connecting seat 508, clamping cylinder 509, connecting plate 510, connecting arm 511, coating jaw 512, mandrel jaw 513, and mandrel 514 to rotate counterclockwise one revolution. Simultaneously, under the clamping of the second coating roller 706 and the pressing plate 906, the film material 515 is kept in a taut state during winding, thus tightly winding the film material 515 onto the mandrel 514 and preventing air bubbles from forming during winding. At the same time, the servo motor 501 pauses, the second slide cylinder 602 extends, and drives the first coating roller 604 to approach and contact the film material 515 that has been wound once, via the first U-shaped frame 603. When the first coating roller 609 rotates counterclockwise one revolution, the second slide cylinder 506 rotates counterclockwise one revolution. 4. After pressing the film material 515 onto the mandrel 514, adjust the air outlet of the hot air gun 405 to align with the film material 515 and blow hot air to soften it. At the same time, the servo motor 501 starts, causing the mandrel 514 to rotate and wind the film material 515. During the winding process, the film material 515 is wound more tightly and without air bubbles with the cooperation of the first rubber coating roller 604, the second rubber coating roller 706 and the pressing plate 906. Finally, the spot welding mechanism 704 spot welds and seals the ends of the tube at multiple locations. During the winding process, the correction sensor 801 checks the data of the film roll offset and uploads it to the external controller. The external controller controls the second slide cylinder 602, the third slide cylinder 701 and the fourth slide cylinder 902 to cooperate in correcting the position of the left and right film material 515.Meanwhile, the servo motor 501 can output constant torque during the tube winding process, ensuring consistent tension at any position of the tube. In conjunction with the torque sensor 503, it can monitor and provide feedback on the tension data during the tube winding process, using this data to confirm whether the winding tension is up to standard.

10. The method of using the film material winding tube apparatus according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Install the mandrel (514) in the left and right mandrel clamps (513) in advance, and then the external controller controls the movement of the Z-axis lead screw module (201) and the first Y-axis lead screw module (202) to adjust the position of the film material winding tube mechanism (3) for subsequent winding. Step 2: The clamping cylinder (509) is extended by the external controller, so that the rubber-coated gripper (512) opens. Then the fourth slide cylinder (902) extends and drives the abutment plate (906) to move upward to the highest point. Step 3: Next, the strip-shaped film material (515) is fed into the mandrel (514) through the top of the clamping plate (906). At this time, the pull handle (516) of the film material (515) is located inside the coating gripper (512). Then, the external controller controls the clamping cylinder (509) to reset and clamps the pull handle (516) of the film material (515) and the mandrel (514) together through the coating gripper (512) to form a preliminary positioning. Then, the external controller controls the film material initial positioning CCD (11) to work and detect the position of the film material. Step 4: When the initial positioning is accurate, the external controller controls the second Y-axis lead screw module (401) to work and drives the softening mechanism (4) and the pressing spot welding mechanism (7) to move to the right through the mounting bracket (402) until the second coating roller (706) moves above the abutment plate (906). At the same time, the third slide cylinder (701) extends and drives the second coating roller (706) to move downward through the second U-shaped frame (705) and contact the film material (515). Then, the external controller controls the servo motor 501 to work. The servo motor 501 drives the transmission shaft (502) to rotate counterclockwise through the coupling and torque sensor (503). The transmission shaft (502) drives the two first pulleys (504) on it to rotate. The first pulleys (504) rotate through the belt (515). 07) Drive the second pulley (506) to rotate. The second pulley (506) drives the connecting seat (508), clamping cylinder (509), connecting plate (510), connecting arm (511), rubber-coated gripper (512), mandrel gripper (513) and mandrel (514) to rotate counterclockwise one revolution. At the same time, under the clamping of the second rubber-coated roller (706) and the pressing plate (906), the film material (515) is kept in a tight state during the winding process, so that the film material (515) is tightly wound on the mandrel (514) to avoid air bubbles during the winding process. At the same time, the servo motor (501) stops, the second slide cylinder (602) extends and drives the first rubber-coated roller (604) to approach and contact the film material (515) that has been wound once through the first U-shaped frame (603). Step 5: After the first coating roller (604) in Step 4 presses the film material (515) onto the mandrel (514), adjust the air outlet of the hot air gun (405) to align with the film material (515) and blow hot air to soften it. At the same time, the servo motor (501) starts, causing the mandrel (514) to rotate and wind the film material (515). During the winding process, the film material (515) is wound more tightly and without air bubbles with the cooperation of the first coating roller (604), the second coating roller (706), and the pressing plate (906). Finally, the spot welding mechanism (704) finishes the winding. Multiple spot welds are applied to the ends of the tubes; during the winding process, the correction sensor (801) checks the data of the film offset and uploads it to the external controller, which controls the second slide cylinder (602), the third slide cylinder (701) and the fourth slide cylinder (902) to cooperate in correcting the position of the left and right film materials (515); at the same time, the servo motor (501) in the winding process can output constant torque to ensure that the tension at any position of the winding tube is consistent. In addition, the torque sensor (503) can monitor and feed back the tension data in the winding process, and use this data to confirm whether the winding tension is qualified.
