Description

Technical Field

[0001] This utility model relates to the technical field of laminating machines, and in particular to a self-rolling rewinding laminating machine. Background Technology

[0002] In the winding process of flexible materials such as films and adhesives, the winding rod of the laminating machine is usually required to bond the adhesive to the film before winding it into shape. Traditional laminating machines usually have a support structure for fixing the winding rod. For example, patent number CN202421186600.7 discloses a winding device for a laminating machine, which realizes the winding operation by installing a winding roller for winding the material at the support plate. However, after the winding is completed, the movable limit plate needs to be manually removed to unload the material, resulting in a long downtime and reducing the working efficiency of the laminating machine. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: a self-rolling rewinding and coating machine, including a worktable, and a feed roller, a traction roller, a transmission assembly and a take-up roller arranged sequentially from front to back on the worktable, as well as an unwinding shaft for mounting the bottom of the worktable. The transmission assembly includes a conveyor belt, a traction roller and a motor. The two ends of the conveyor belt are connected to the worktable through the traction roller. The motor controls the movement of the conveyor belt through the traction roller. It also includes a take-up rod. The conveyor belt and the take-up roller are combined to form a limiting groove for accommodating the take-up rod. The take-up rod self-rolls and rewinds within the limiting groove.

[0004] Using the above technical solution, the worker first winds one end of the film on the unwinding shaft to the take-up rod, and then pulls the adhesive material through the feed roller, traction roller, and conveyor belt to the take-up rod, so that the adhesive material and film adhere together and the take-up rod is placed in the limiting groove. At this time, the conveyor belt drives the take-up rod to roll and rotate, realizing automatic winding operation. No external winding structure is required. The take-up rod can be easily removed from the limiting groove and unloaded, which is convenient for continuous production and improves production efficiency.

[0005] The present invention is further configured such that the conveyor belt and the winding drum rotate in the same direction, and the winding rod simultaneously abuts against the conveyor belt and the winding drum.

[0006] Furthermore, a gearbox is provided on one side of the workbench, and a driving gear, a steering gear and a driven gear are provided in the gearbox. The traction roller and the winding roller are coaxially connected to the driving gear and the driven gear, respectively. The driving gear is connected to the driven gear through the steering gear.

[0007] Furthermore, the transmission ratio between the driving gear and the driven gear is 1:1.

[0008] Using the above technical solution, the motor drives the conveyor belt and the winding drum to rotate synchronously in the same direction. The winding rod is tangent to the surface of the conveyor belt and the winding drum, and the conveyor belt and the winding drum drive the winding rotation through friction to meet the winding requirements. Since the transmission ratio of the driving gear and the driven gear is 1:1, there is no relative friction between the winding rod and the conveyor belt or the winding drum, thereby avoiding the stretching or squeezing of the film or rubber material during the winding process.

[0009] The present invention is further configured such that the worktable is rotatably connected to feed rollers arranged in a straight line, and multiple sets of feed rollers are combined to form a virtual plane for conveying rubber material, and the traction pressure roller and the conveyor belt are respectively arranged on the upper and lower sides of the virtual plane.

[0010] Using the above technical solution, multiple sets of feed rollers are arranged in a straight line, and their upper surfaces are combined to form a virtual plane for conveying the adhesive. This plane serves as a reference plane for the movement of the adhesive, ensuring that the adhesive remains flat in the laminating machine.

[0011] The present invention is further configured such that the worktable is provided with limiting components at both ends of the feeding roller. The limiting components include a double helical screw and a column rotatably connected to the worktable, and limiting plates meshing with both sides of the double helical screw. The limiting plates are slidably connected to the column, and the limiting plates are provided with circular grooves for avoiding the feeding roller.

[0012] Furthermore, one end of the double helix screw is provided with an adjusting handwheel, which controls the two sets of limiting plates to move in opposite directions.

[0013] By adopting the above technical solution, the spacing of the limiting plates can be adjusted by rotating the handwheel, thereby indirectly adjusting the feeding width of the adhesive material, ensuring that the adhesive material is placed in the center and improving the coating accuracy.

[0014] The present invention is further configured such that the traction roller includes a bracket, an upper traction roller, a lower traction roller and a cylinder. The bracket is connected to both sides of the worktable. The upper traction roller is slidably connected to the upper end of the bracket, and the lower traction roller is rotatably connected to the lower end of the bracket. The bracket is fixedly connected to a cylinder for controlling the up and down movement of the upper traction roller.

[0015] Using the above technical solution, when the cylinder controls the upper traction roller to move downward, the rubber material is simultaneously squeezed by the upper and lower traction rollers, ensuring that the rubber material squeezed onto the conveyor belt has a uniform thickness and a flat surface, so that the radial pressure on the winding rod during self-rolling is evenly distributed, and the finished rubber material has no local protrusions or depressions.

[0023] The embodiments of this utility model will now be described with reference to the accompanying drawings. In this process, to ensure clarity and convenience, we may exaggerate the width of lines or the size of constituent elements in the drawings.

[0024] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the intentions or conventions of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0025] like Figure 1 , 2 As shown, a self-rolling rewinding and coating machine includes a worktable 1, and a feed roller 2, a traction pressure roller 3, a transmission assembly 4, and a take-up roller 5 arranged sequentially from front to back on the worktable 1, as well as an unwinding shaft 6 for mounting the bottom of the worktable 1. The transmission assembly 4 includes a conveyor belt 41, a traction roller 42, and a motor 43. The two ends of the conveyor belt 41 are connected to the worktable 1 through the traction roller 42. The motor 43 controls the movement of the conveyor belt 41 through the traction roller 42. The machine also includes a take-up rod 7. The conveyor belt 41 and the take-up roller 5 are combined to form a limiting groove 10 for accommodating the take-up rod 7. The take-up rod 7 self-rolls and rewinds within the limiting groove 10.

[0026] Combination Figure 3As shown, in this embodiment, the conveyor belt 41 and the winding drum 5 rotate in the same direction. The winding rod 7 simultaneously abuts against the conveyor belt 41 and the winding drum 5. A gearbox 11 is provided on one side of the workbench 1, and a driving gear 12, a steering gear 13, and a driven gear 14 are provided in the gearbox 11. The traction roller 42 and the winding drum 5 are coaxially connected to the driving gear 12 and the driven gear 14, respectively. The driving gear 12 is meshed with the driven gear 14 through the steering gear 13. The driving gear 12 and the driven gear 14 are connected in a specific manner. The transmission ratio is 1:1. The motor 43 drives the conveyor belt 41 and the take-up roller 5 to rotate synchronously in the same direction. The take-up rod 7 is tangent to the surface of the conveyor belt 41 and the take-up roller 5. The conveyor belt 41 and the take-up roller 5 drive the take-up rotation through friction to meet the take-up requirements. Since the transmission ratio of the drive gear 12 to the driven gear 14 is 1:1, there is no relative friction between the take-up rod 7 and the conveyor belt 41 or the take-up roller 5, thereby avoiding the stretching or squeezing of the film 100 or the adhesive during the take-up process.

[0027] In this embodiment, the workbench 1 is rotatably connected to feed rollers 2 arranged in a straight line. Multiple sets of feed rollers 2 are combined to form a virtual plane 15 for conveying the adhesive. The traction pressure roller 3 and the conveyor belt 41 are respectively arranged on the upper and lower sides of the virtual plane 15. The multiple sets of feed rollers 2 are arranged in a straight line, and their upper surfaces are combined to form a virtual plane 15 for conveying the adhesive. This plane serves as a reference plane for the movement of the adhesive, ensuring that the adhesive remains flat in the laminating machine.

[0028] In this embodiment, the workbench 1 is provided with limiting components 8 at both ends of the feed roller 2. The limiting components 8 include a double helical screw 81 and a column 82 rotatably connected to the workbench 1, and limiting plates 83 meshing with both sides of the double helical screw 81. The limiting plates 83 are slidably connected to the column 82, and the limiting plates 83 are provided with circular grooves 85 for avoiding the feed roller 2. One end of the double helical screw 81 is provided with an adjusting handwheel 84. The adjusting handwheel 84 controls the two sets of limiting plates 83 to move in opposite directions. By rotating the handwheel to adjust the distance between the limiting plates 83, the feeding width of the adhesive is indirectly adjusted to ensure that the adhesive is placed in the center and improve the coating accuracy.

[0029] Combination Figure 4As shown, in this embodiment, the traction roller 3 includes a bracket 31, an upper traction roller 32, a lower traction roller 33, and a cylinder 34. The bracket 31 is connected to both sides of the workbench 1. The upper traction roller 32 is slidably connected to the upper end of the bracket 31, and the lower traction roller 33 is rotatably connected to the lower end of the bracket 31. The cylinder 34 for controlling the up and down movement of the upper traction roller 32 is fixedly connected to the bracket 31. When the cylinder 34 controls the upper traction roller 32 to move down, the rubber material is simultaneously squeezed by the upper traction roller 32 and the lower traction roller 33, ensuring that the rubber material squeezed onto the conveyor belt 41 has a uniform thickness and a flat surface, so that the radial pressure on the winding rod 7 during self-rolling is evenly distributed, and the finished rubber material has no local protrusions or depressions.

[0030] Combination Figure 5 As shown, the working principle of this utility model is as follows: First, the operator pulls the film 100 out from the unwinding shaft 6, passes it through the gap between the conveyor belt 41 and the winding roller 5, and winds it onto the winding rod 7; then, according to the width of the adhesive 200, the operator rotates the adjusting handwheel 84, which drives the two sets of limiting plates 83 to move synchronously through the double helical screw 81, so that the adhesive 200 is centered on the feed roller 2; next, the adhesive 200 passes through the feed roller 2, the traction pressure roller 3, and the conveyor belt 41 in sequence, and is wound onto the winding rod 7 together with the film 100; then, the cylinder 34 drives the upper traction roller... 32 presses down, and together with the lower traction roller 33, squeezes the rubber material 200 to make the thickness of the rubber material 200 uniform. After the motor 43 drives the conveyor belt 41 to start, the conveyor belt 41 and the take-up roller 5 rotate synchronously in the same direction through the gearbox 11. The operator places the take-up rod 7 into the limiting groove 10, so that the take-up rod 7 rolls and rotates with the conveyor belt 41 under the action of friction, automatically winding and winding the rubber material 200 and the film 100. Finally, after the winding is completed, the take-up rod 7 is axially removed from the roll and unloaded. The above actions are repeated to carry out the next round of operation, realizing continuous production.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
