Description

Technical Field

[0001] This utility model relates to the field of coating machine feeding technology, specifically a feeding mechanism for a film coating machine. Background Technology

[0002] A film coating machine is a device used to coat a film surface with a specific material. It is widely used in packaging materials, electronic products, new energy and other fields. Through the coating process, a coating with specific properties is formed on the film surface.

[0003] For example, in a coating machine feeding and positioning structure with announcement number "CN213264876U", the film is wound onto a collecting cylinder. A collecting motor drives the collecting cylinder to rotate, thereby winding the film. The film passes through the gap between the pressure roller and the collecting roller. The pressure roller presses the film against the circumference of the collecting cylinder. As more and more film is collected, the first spring will relax according to the thickness of the film. The cooperation between the pressure roller and the first spring ensures that the film is tightened each time it is wound. However, this coating machine feeding and positioning structure uses a bidirectional screw to press against the upper surface of the film to prevent the film from shifting. However, the bidirectional screw cannot move up and down, and it is not suitable for most films with different thicknesses, which has limitations. In addition, this coating machine feeding and positioning structure requires adjusting the pressure roller by turning multiple bolts, which consumes a lot of time for the operator and reduces the operator's work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the current coating machine feeding and positioning structure, which uses a bidirectional lead screw to press against the upper surface of the film to prevent the film from shifting. However, the bidirectional lead screw cannot move up and down, and it is not suitable for most films with different thicknesses, which has limitations. Also, the current coating machine feeding and positioning structure requires adjusting the pressure wheel by turning multiple bolts, which consumes a lot of time for the operator and reduces the operator's work efficiency. Therefore, this invention proposes a film coating machine feeding mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A third curved plate is fixedly connected to the upper right side of the base plate.

[0007] Preferably, a first cylinder is fixedly connected to the outer wall of the third curved plate, and a second housing is fixedly connected to the output end of the first cylinder. An adjustment mechanism is provided inside the second housing.

[0008] Preferably, the pressing mechanism includes a handle, the upper end of which is fixedly connected to the rotating shaft of a first helical gear. The rotating shaft of the first helical gear is rotatably connected to the first housing via a bearing. The first helical gear meshes with a second helical gear. The lower end of the rotating shaft of the second helical gear is fixedly connected to a protruding plate. The outer wall of the protruding plate abuts against a pressure plate. Springs are sleeved on the lower outer wall of the pressure plate. The two ends of the two springs are respectively fixedly connected to the first housing and the pressure plate. The outer wall of the pressure plate is slidably connected to the first housing. The threaded rod is threadedly connected to the handle.

[0009] Preferably, the lower end of the pressure plate is fixedly connected to the fifth bending plate, and the rubber sleeve at the lower end of the threaded rod abuts against the first outer shell.

[0010] Preferably, a piston is fixedly connected to the lower end of the outer wall of the second outer shell, a fourth curved plate is fixedly connected to the lower end of the piston, the inner wall of the fourth curved plate is rotatably connected to the first pressure roller through a bearing, a first vertical plate is fixedly connected to the upper front side of the bottom plate, a first servo motor is fixedly connected to the outer wall of the first vertical plate, and a cylinder is fixedly connected to the output shaft of the first servo motor.

[0011] Preferably, the adjustment mechanism includes a second servo motor, the output shaft of which is fixedly connected to a worm gear, the worm gear meshing with a worm wheel, the end of the worm gear being rotatably connected to a second housing via a bearing, the rotating shaft of the worm wheel being fixedly connected to a rotating rod, both ends of the rotating rod being movably connected to a connecting rod via pins, the outer ends of the connecting rod being movably connected to a slider via pins, and the inner wall of the slider being slidably connected to a sliding rod machined on the second housing.

[0012] Preferably, a piston is fixedly connected to the lower end of the outer wall of each slider, and a fourth curved plate is fixedly connected to the lower end of each piston. The outer wall of the second servo motor is fixedly connected to the second outer shell.

[0013] Preferably, the outer wall of the cylinder is abutted against the sleeve by two pins, the front end of the cylinder is slidably connected to the bearing sleeve, the outer wall of the bearing sleeve is rotatably connected to the second vertical plate by a bearing, the lower end of the outer wall of the second vertical plate is in contact with the base plate, the front end of the outer wall of the second vertical plate is fixedly connected to the output end of the second cylinder, and the second cylinder is fixedly connected to the base plate.

[0014] The present invention provides a feeding mechanism for a film coating machine, which has the following advantages: Through the cooperation of the pressing mechanism and the first curved plate, the handle rotates clockwise to drive the first helical gear to rotate, which in turn drives the second helical gear to rotate. The rotation of the second helical gear drives the convex plate to rotate, which in turn drives the pressure plate to move downward. The downward movement of the pressure plate compresses the spring. The pressure plate moves vertically downward due to the limitation of the first outer shell. The downward movement of the pressure plate drives the fifth curved plate to move downward, which in turn drives multiple second pressure rollers to move downward. When the lower outer wall of the second pressure roller is pressed against the film, the threaded rod is tightened, so that the threaded rod is pressed against the first outer shell. The maximum elastic force generated by the spring is less than the frictional force generated after the threaded rod is pressed against the film, thus achieving self-locking and keeping the second pressure roller in this state. This achieves the downward pressing of the second pressure roller. The height of the second pressure roller can be adjusted according to the thickness of the film to achieve the second pressure roller pressing against films of different thicknesses, preventing film wrinkles and reducing limitations.

[0015] Through the coordination of the adjustment mechanism and the first cylinder, the output shaft of the second servo motor rotates forward, driving the worm gear to rotate, which in turn drives the worm wheel to rotate. The rotation of the worm wheel drives the rotating rod to rotate, which in turn drives the inner ends of the connecting rods on both sides to move in the same direction as the ends of the connecting rods. The two connecting rods move in opposite directions, causing the two sliders to move inward along the sliding rods machined on the second outer shell. When the rotating rod rotates 90 degrees, the movement of the two sliders drives the piston to move, thereby causing the fourth curved plate to fit against the fourth outer wall fixed at the lower end of the second outer shell. This brings the three first pressure rollers to their closest distance. The position of the first pressure rollers is adjusted according to the width of the film. After adjusting to the appropriate position, the second servo motor is stopped. Because the worm gear and worm wheel have self-locking properties, the two fourth curved plates are kept in this state, thus realizing the position adjustment of the fourth curved plates. The adjustment mechanism adjusts the position of the fourth curved plates, eliminating the need for workers to manually tighten multiple bolts to adjust the fourth curved plates, saving workers' time and improving work efficiency.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] See attached document Figure 1-7 :

[0026] In this embodiment, a film coating machine feeding mechanism includes a base plate 1. A first curved plate 2 is fixedly connected to the upper left side of the base plate 1. A second curved plate 3 is fixedly connected to the upper end of the first curved plate 2. A first outer shell 4 is fixedly connected to the outer wall of the second curved plate 3. A pressing mechanism 5 is provided inside the first outer shell 4. A fifth curved plate 16 is provided below the pressing mechanism 5. The inner wall of the fifth curved plate 16 is rotatably connected to a plurality of second pressure rollers 17 through bearings. The plurality of second pressure rollers 17 press the film and can rotate, effectively preventing the film from wrinkling. A third curved plate 9 is fixedly connected to the upper right side of the base plate 1. A first cylinder 6 is fixedly connected to the outer wall of the third curved plate 9. A second outer shell 7 is fixedly connected to the output end of the first cylinder 6. An adjustment mechanism 8 is provided inside the second outer shell 7.

[0027] The output end of the first cylinder 6 extends and retracts, causing the second outer shell 7 to move, which in turn causes the adjustment mechanism 8 to move. A piston 21 is fixedly connected to the lower end of the outer wall of the second outer shell 7. A fourth curved plate 10 is fixedly connected to the lower end of the piston 21. The inner wall of the fourth curved plate 10 is rotatably connected to the first pressure roller 11 through a bearing. The movement of the adjustment mechanism 8 causes the piston 21 to move, which in turn causes the fourth curved plate 10 and the first pressure roller 11 to move. A first vertical plate 15 is fixedly connected to the front side of the upper end of the base plate 1. A first servo motor 14 is fixedly connected to the outer wall of the first vertical plate 15. A cylinder 13 is fixedly connected to the output shaft of the first servo motor 14. The rotation of the output shaft of the first servo motor 14 causes the cylinder 13 to rotate. The outer wall of the cylinder 13 is pressed against the round sleeve 12 through two pins. The round sleeve 12 has a limiting function to prevent the film from shifting.

[0028] The front end of the cylinder 13 is slidably connected to the bearing sleeve 18. The outer wall of the bearing sleeve 18 is rotatably connected to the second vertical plate 19 through the bearing. The rotation of the cylinder 13 drives the bearing sleeve 18 to rotate, and the cylinder 13 can be separated from the bearing sleeve 18. The lower end of the outer wall of the second vertical plate 19 is in contact with the base plate 1. The base plate 1 prevents the second vertical plate 13 from flipping. The front end of the outer wall of the second vertical plate 19 is fixedly connected to the output end of the second cylinder 20. The extension and retraction of the output end of the second cylinder 20 drives the second vertical plate 19 to move. The second cylinder 20 is fixedly connected to the base plate 1.

[0029] See attached document Figure 1-2 And 4:

[0030] The pressing mechanism 5 includes a handle 501. The upper end of the handle 501 is fixedly connected to the rotating shaft of the first helical gear 502. The rotating shaft of the first helical gear 502 is rotatably connected to the first housing 4 through a bearing. The first helical gear 502 meshes with the second helical gear 503. Rotating the handle 501 drives the first helical gear 502 to rotate, thereby driving the second helical gear 503 to rotate. The lower end of the rotating shaft of the second helical gear 503 is fixedly connected to a protruding plate 504. The rotation of the second helical gear 503 drives the protruding plate 504 to rotate. The outer wall of the protruding plate 504 abuts against the pressure plate 505. The lower outer wall of the pressure plate 505 is sleeved with springs 506.

[0031] The rotation of the convex plate 504 drives the pressure plate 505 to move. The pressure plate 505 moves vertically up and down, with the first outer shell 4 as the limit. The two ends of the two springs 506 are respectively fixedly connected to the first outer shell 4 and the pressure plate 505. The movement of the pressure plate 505 compresses the springs 506. The outer wall of the pressure plate 505 is slidably connected to the first outer shell 4. The threaded rod 507 is threadedly connected to the handle 501. The lower end of the pressure plate 505 is fixedly connected to the fifth curved plate 16. The rubber sleeve at the lower end of the threaded rod 507 abuts against the first outer shell 4. The spring 507 presses against the first outer shell 4. The anti-slip effect of the rubber sleeve makes the pressing more stable, thus achieving self-locking.

[0032] See attached document Figure 1-3 And 6:

[0033] The adjustment mechanism 8 includes a second servo motor 801. The output shaft of the second servo motor 801 is fixedly connected to a worm gear 802. The worm gear 802 meshes with a worm wheel 803. The rotation of the output shaft of the second servo motor 801 drives the worm gear 802 to rotate, thereby driving the worm wheel 803 to rotate. The end of the worm gear 802 is rotatably connected to the second housing 7 through a bearing. The rotating shaft of the worm wheel 803 is fixedly connected to a rotating rod 804. Both ends of the rotating rod 804 are movably connected to a connecting rod 805 through pins. The outer ends of the connecting rod 805 are movably connected to a slider 806 through pins.

[0034] The worm gear 803 rotates, driving the rotating rod 804 to rotate, which in turn drives the connecting rod 805 to move. The connecting rods 805 on both sides move in opposite directions. The inner wall of the slider 806 is slidably connected to the sliding rod machined in the second outer shell 7. The movement of the connecting rod 805 drives the slider 806 to move. The sliders 806 on both sides move in opposite directions. The lower end of the outer wall of the slider 806 is fixedly connected to a piston 21. The lower end of the piston 21 is fixedly connected to a fourth curved plate 10. The outer wall of the second servo motor 801 is fixedly connected to the second outer shell 7.

[0035] Working principle:

[0036] When it is necessary to feed the film from the film coating machine.

[0037] Preparation process:

[0038] First, the operator controls the output end of the second cylinder 20 to retract (e.g.) Figure 7 The output end of the second cylinder 20 retracts, causing the second vertical plate 19 to move to the right. The movement of the second vertical plate 19 to the right causes the bearing sleeve 18 to move to the right, disengaging the bearing sleeve 18 from the cylinder 13. Then, the right-side circular sleeve 12 is removed, and the collecting sleeve is fitted onto the cylinder 13. The right-side circular sleeve 12 is then reinstalled and pressed against the collecting sleeve. During installation, the two circular sleeves 12 fix the center of the collecting sleeve at the center position of the cylinder 13, limiting the collecting sleeve. Then, the bolts are tightened to press the circular sleeve 12 against the cylinder 13. The film output from the film coating machine is then laid flat on the first curved plate 2, passing under the second pressure roller 17 and fixed to the collecting sleeve (e.g., Figure 2 Then loosen the threaded rod 507 and turn the handle 501 (as shown). Figure 4The handle 501 rotates clockwise, causing the first helical gear 502 to rotate, which in turn drives the second helical gear 503 to rotate. The rotation of the second helical gear 503 drives the convex plate 504 to rotate, which in turn drives the pressure plate 505 to move downward. The downward movement of the pressure plate 505 compresses the spring 506. The pressure plate 505 moves vertically downward due to the limitation of the first outer shell 4. The downward movement of the pressure plate 505 drives the fifth curved plate 16 to move downward, which in turn drives multiple second pressure rollers 17 to move downward. When the lower outer wall of the second pressure roller 17 is pressed against the film, the threaded rod 507 is turned, so that the threaded rod 507 is pressed against the first outer shell 4. The maximum elastic force generated by the spring 506 is less than the frictional force generated after the threaded rod 507 is pressed against the film, thus achieving self-locking and keeping the second pressure roller 17 in this state. Then the second servo motor 801 is started (e.g., Figure 3 The output shaft of the second servo motor 801 rotates clockwise, driving the worm gear 802 to rotate, which in turn drives the worm wheel 803 to rotate. The worm wheel 803 rotates, driving the rotating rod 804 to rotate. The rotating rod 804 rotates, causing the inner ends of the connecting rods 805 on both sides to move in the same direction as the ends of the connecting rods 805. The two connecting rods 805 move in opposite directions, causing the two sliders 806 to move inward along the sliding rods machined on the second outer shell 7. When the rotating rod 804 rotates ninety degrees, the movement of the two sliders 806 drives the piston 21 to move, thereby causing the fourth curved plate 10 to fit against the fourth outer wall 10 fixed at the lower end of the second outer shell 7, so that the three first pressure rollers 11 reach the closest distance. According to the width of the film, the first... The position of the first pressure roller 11 is adjusted. After adjusting to the appropriate position, the second servo motor 801 is stopped. Because the worm 802 and worm wheel 803 have self-locking properties, the two fourth bending plates 10 are kept in this state. If the first pressure roller 11 needs to move outward, the second servo motor 801 can be reversed. The working principle is the opposite of the above. Then the first cylinder 6 is started. The output end of the first cylinder 6 extends and drives the second housing 7 downward, thereby driving the adjustment mechanism 8 to move downward. The adjustment mechanism 8 moves downward and drives the first pressure roller 11 to move downward. When the first pressure roller 11 is pressed against the film, the first cylinder 6 is stopped, which realizes the pressing and limiting of the film and prevents the film from running around during collection.

[0039] Work process:

[0040] Start the second servo motor 14 (e.g.) Figure 2The output shaft of the second servo motor 14 rotates, causing the cylinder 13 to rotate, which in turn causes the sleeve 12 on the cylinder 13 to rotate. Because the inner side of the sleeve 12 presses against the collecting sleeve, and the size of the collecting sleeve is similar to that of the cylinder 13 with little gap, the rotation of the cylinder 13 causes the collecting sleeve to rotate, which in turn causes the film to rotate. The film's movement causes the first pressure roller 11 and the second pressure roller 17 to rotate. The rotation of the first pressure roller 11 and the second pressure roller 17 serves to transport the film. As the film becomes thicker, the first pressure roller 11 moves upward, causing the output end of the piston 21 to move upward, which in turn moves the piston... The internal air of cylinder 21 is compressed to ensure that the first pressure roller 11 presses against the film while moving upward. After the film is wound, the first servo motor 14 is turned off, and then the first cylinder 6 is restarted to retract the output end of the first cylinder 6 to the limit position, so that the first pressure roller 11 is separated from the film. Then, because the piston 21 is no longer limited, the internal air pressure is released, which drives the output end to reset. Then the second cylinder 20 is started. The working principle of the output end of the second cylinder 20 is the same as above, and the collection sleeve is removed. If it is necessary to continue feeding, the above operation can be repeated. After all is completed, all power can be turned off.
