Description

Technical Field

[0001] This invention relates to the field of coating production technology, specifically a biaxial winding structure. Background Technology

[0002] Coating is a process based on the study of fluid properties, in which one or more layers of liquid are coated onto a substrate, which is usually a flexible film or paper backing. The coated liquid coating is then dried in an oven or cured to form a film layer with special functions.

[0003] The final step in coating production is winding. Existing dual-shaft winding devices generally use detachable air shafts. After winding, the winding shaft and film roll need to be removed together, which takes a long time. At the same time, the air shaft has a large installation gap and poor concentricity after inflation, which can lead to large winding bounce. In addition, the existing cutter is generally fixed on a large swing arm. During use, the swing arm of the cutter has a large range of motion and the movement process is relatively complex, so the cutting reliability needs to be improved.

[0004] In view of this, we propose a dual-axis winding structure. Summary of the Invention

Therefore, they should not be construed as limitations on this invention.

[0049] Please see Figure 1-9 The present invention will describe the above technical solution in detail through the following embodiments:

[0050] A biaxial winding structure includes:

[0051] The base 1 includes a base bracket 12. A transverse moving bracket 15 is mounted on the top surface of the base bracket 12 via a transverse guide rail 13. A first guide slider 14 is fixedly mounted on the bottom of the transverse moving bracket 15 by bolts. The first guide slider 14 is engaged with the transverse guide rail 13. The transverse moving bracket 15 can move left and right under the drive of a first cylinder 16. A fixed foot 11 is welded to the bottom of the base bracket 12.

[0052] The first cylinder 16 is mounted in the middle of the base bracket 12 via a hinge. The top of the piston rod of the first cylinder 16 is connected to the transverse moving bracket 15 via a hinge. By controlling the extension or retraction of the piston rod of the first cylinder 16, the transverse moving bracket 15 can be driven to slide left and right in the horizontal direction.

[0053] A support plate 17 is welded to the top surface of the transverse moving bracket 15. A longitudinal guide rail 19 is bolted to the top surface of the support plate 17. A support beam 18 is welded between the longitudinal guide rails 19 and located in the middle of the transverse moving bracket 15.

[0054] Also includes:

[0055] The feeding assembly 2 includes a vacuum traction roller 25, which is driven by a traction motor 26 and can move the film forward. The feeding assembly 2 also includes a feeding bracket 21. The vacuum traction roller 25 is rotatably mounted between the feeding brackets 21. An adjustment component housing 22 is fixedly mounted on the right side of the feeding bracket 21 by bolts. The traction motor 26 is mounted in the adjustment component housing 22 by bolts. The traction motor 26 and the vacuum traction roller 25 are connected by a first gear transmission device 27.

[0056] After the traction motor 26 is powered on and started, the shaft of the traction motor 26 begins to rotate. The first gear transmission device 27 can transmit the rotation of the shaft of the traction motor 26 to the vacuum traction roller 25, thereby driving the vacuum traction roller 25 to rotate.

[0057] The feeding bracket 21 is fixedly installed on the top surface of the support plate 17 by bolts. The support rod 23 is fixedly installed between the feeding brackets 21. The first guide roller 24 is rotatably installed at the bottom rear of the vacuum traction roller 25 and between the feeding brackets 21. The second guide roller 28 and the third guide roller 29 are rotatably installed at the upper front of the vacuum traction roller 25 and between the feeding brackets 21.

[0058] Tensioning assembly 3 includes a floating roller 31, which is connected to an adjusting cylinder 35 via an adjusting transmission device. The floating roller 31 is raised or lowered by controlling the extension or retraction of the piston rod of the adjusting cylinder 35.

[0059] The coating enters from below the first guide roller 24, passes in front of the vacuum traction roller 25, then goes around behind the second guide roller 28, then goes around above the floating roller 31 and extends downward, passing under the third guide roller 29. At this time, the direction of movement of the coating becomes horizontal after passing the third guide roller 29.

[0060] The adjustment transmission device includes a floating roller adjustment plate 32. One end of the floating roller adjustment plate 32 is rotatably connected to the floating roller 31, and the other end is fixedly connected to an adjustment shaft 33. The adjustment shaft 33 is rotatably mounted on the feeding bracket 21 and its right end extends through the feeding bracket 21 into the adjustment assembly housing 22. A transmission plate 34 is fixedly mounted on the right end of the adjustment shaft 33, and the transmission plate 34 is hinged to the piston rod of the adjustment cylinder 35.

[0061] The adjusting cylinder 35 is a low-friction cylinder. The low-friction cylinder has high sensitivity and can accurately control the piston rod movement distance. By controlling the extension or shortening of the piston rod of the adjusting cylinder 35, the transmission plate 34 can be driven to rotate the adjusting shaft 33, thereby driving the floating roller adjusting plate 32 to rotate, and then driving the floating roller 31 to rise or fall, so as to adjust the winding pressure of the coating.

[0062] The pressure roller moving carriage 4 includes pressure roller fixing plates 42, which are fixed together by moving carriage support beams 43. The moving carriage support beams 43 are connected to the moving carriage drive motor 49 through a screw transmission device, and the moving carriage drive motor 49 can drive the pressure roller moving carriage 4 to move through the screw transmission device. The pressure roller moving carriage 4 is mounted on the longitudinal guide rail 19.

[0063] The bottom surface of the pressure roller fixing plate 42 is fixedly mounted with a pressure roller moving slider 41 by bolts. The pressure roller moving slider 41 is engaged with the longitudinal guide rail 19, and the pressure roller fixing plate 42 can move axially along the longitudinal guide rail 19 through the pressure roller moving slider 41.

[0064] The screw drive device includes a sleeve mounting plate 44. The top of the sleeve mounting plate 44 is bolted to the support beam 43 of the mobile vehicle. The bottom of the sleeve mounting plate 44 is bolted to a threaded sleeve 45. The threaded sleeve 45 is threaded to a first screw 46. The tail end of the first screw 46 is connected to the drive motor 49 of the mobile vehicle through a second gear transmission assembly 48.

[0065] The first screw 46 is rotatably connected to a screw bracket 47 at both ends via bearings. The screw bracket 47 is fixedly mounted on the support beam 18 by bolts. The moving vehicle drive motor 49 can be a servo motor. After the moving vehicle drive motor 49 is started, it can drive the first screw 46 to rotate through the second gear transmission assembly 48. Since the first screw 46 is threadedly connected to the threaded sleeve 45, when the first screw 46 rotates, it will drive the threaded sleeve 45 to move along the axis of the first screw 46, thereby driving the moving vehicle support beam 43 to move, and then driving the pressure roller fixing plate 42 to move.

[0066] The pressure roller assembly 5 is installed between the pressure roller fixing plates 42. The pressure roller assembly 5 includes a pressure roller 51. The pressure roller 51 is connected to a pressure roller control cylinder 53 through a pressure roller sliding bracket 52. The pressure roller control cylinder 53 can drive the pressure roller 51 to move forward or backward.

[0067] By controlling the piston rod of the pressure roller control cylinder 53 to extend or retract, the pressure roller sliding bracket 52 can be driven to move forward or backward, thereby driving the pressure roller 51 to move forward or backward.

[0068] The pressure roller assembly 5 also includes a pressure plate 54, which is bolted to the pressure roller fixing plates 42 and located on the upper and lower sides in front of the pressure roller 51. A cutter 58 is provided in front of the pressure plate 54, and rotating connecting plates 56 are fixedly connected to both ends of the cutter 58. The rotating connecting plates 56 are rotatably mounted on the pressure roller fixing plates 42 via connecting plate pivots 57. A cutter control cylinder 55 is hinged to the tail end of the rotating connecting plate 56, and the cutter control cylinder 55 is bolted to the pressure roller fixing plates 42.

[0069] By controlling the piston rod of the cutter control cylinder 55 to extend or retract, the rotating connecting plate 56 can be driven to rotate around the connecting plate shaft 57, thereby driving the cutter 58 to rise or fall and achieve membrane cutting.

[0070] The winding bracket 6 is used to install the winding assembly 7. The winding bracket 6 includes a winding machine housing 61 and a winding support 62. A winding drive shaft 63 is rotatably installed between the winding machine housing 61 and the winding support 62. A winding cross bracket 64 and a straight winding bracket 65 are fixedly installed on the winding drive shaft 63 and located between the winding machine housing 61 and the winding support 62. The winding assembly 7 is installed between the winding cross bracket 64 and the straight winding bracket 65.

[0071] The winding housing 61 and the winding support 62 are fixedly mounted on the support plate 17 by bolts. The winding drive shaft 63 passes through the winding housing 61 and is engaged with a worm gear 67. A worm 68 is meshed below the worm gear 67. By controlling the rotation of the worm 68, the worm gear 67 can be driven to rotate. Driving the worm gear 67 to rotate can drive the winding drive shaft 63 to rotate, thereby driving the winding cross bracket 64 and the straight winding bracket 65 to rotate, realizing the position conversion of the winding assembly 7.

[0072] Two take-up guide rollers 66 are rotatably mounted between the take-up cross bracket 64 and the straight take-up bracket 65. The take-up guide rollers 66 are used to change the direction of the coating movement.

[0073] The winding assembly 7 includes a winding roller 73, which includes a tensioning plate 739. The tensioning plate 739 is pneumatically tensioned and has a consistent tensioning height.

[0074] The winding assembly 7 also includes a winding motor 71, which is symmetrically mounted on the side of the winding cross bracket 64 near the winding machine housing 61 by bolts. The winding motor 71 is fixedly connected to a third gear transmission assembly 72. The left end of the winding roller 73 passes through the winding cross bracket 64 and is connected to the third gear transmission assembly 72. The right end of the winding roller 73 is rotatably connected to a winding roller fixing plate 74. A U-shaped bracket 75 is fixedly installed on the side of the winding roller fixing plate 74 near the straight winding bracket 65. The U-shaped bracket 75 is connected to a U-shaped plate fixing bracket 76 by a limiting pin 77 and a rotating rod 78. The U-shaped plate fixing bracket 76 is welded to the straight winding bracket 65.

[0075] After the winding motor 71 is powered on and started, it can drive the winding roller 73 to rotate through the third gear transmission assembly 72, thereby realizing winding. The right end of the winding roller 73 is connected to the winding roller fixing plate 74 through a bearing, with the right end pressing against the bearing. The bearing is fixedly installed in the middle of the winding roller fixing plate 74. After winding is completed, the limit pin 77 can be removed. At this time, the winding roller fixing plate 74 and the U-shaped bracket 75 can rotate around the rotating rod 78.

[0076] The take-up roller 73 also includes a roller 733. Both ends of the roller 733 are threadedly connected to end caps 731. An air passage 732 is provided through the left end cap 731. A piston 734 is provided in the left part of the roller 733. A tapered rod 735 is provided on the right side of the piston 734. The tapered rod 735 includes a tapered surface and a cylindrical surface. A movable key 736 is slidably connected to the tapered surface of the tapered rod 735. The movable key 736 passes through the roller 733 and is fixedly connected to the tension plate 739 by bolts. A return spring 738 is sleeved on the tail end of the tapered rod 735. The tail end of the return spring 738 contacts the right end cap 731, and the top end of the return spring 738 abuts against the tail end of the tapered rod 735. An elastic ring 737 is nested on the outside of the movable key 736.

[0077] The top of the right end cap 731 is spherical. The top of the right end cap 731 presses against the bearing in the middle of the take-up roller fixing plate 74. When air is injected into the air passage 732, the air pressure on the left side of the piston 734 increases, and the piston 734 moves to the right, thereby pushing the cone rod 735 to the right. The movement of the cone rod 735 to the right will cause the bottom of the movable key 736 to be squeezed by the conical surface of the cone rod 735, thus moving it upward. This will drive the tensioning plate 739 to move away from the axis of the cone rod 735, achieving tension. At this time, the cone rod 735 will squeeze the return spring 738. When the winding is completed, the injection of air into the air passage 732 stops. At this time, in order to return to its original state, the return spring 738 will squeeze the cone rod 735 to the left, causing the cone rod 735 to move to the left. At this time, the movable key 736 receives the elastic force of the elastic ring 737 and moves towards the axis of the cone rod 735, thereby driving the tensioning plate 739 to move towards the axis of the cone rod 735, achieving retraction.

[0078] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
