Description

Technical Field

[0001] This utility model belongs to the technical field of packaging and printing equipment, and in particular relates to a winding device on a solventless laminating machine. Background Technology

[0002] Solvent-free laminating machines are devices that bond two or more substrates together using solvent-free adhesives, and are widely used in packaging materials, printing, and other fields. The equipment includes a winding device for winding the laminated plastic film, and various rollers for guiding and tensioning the substrates, such as guide rollers, tension rollers, and traction rollers. During long-term production, due to substrate specification adjustments, equipment maintenance, or component wear, the paper rollers used for winding and the guide rollers need frequent replacement, resulting in a large number of old rollers that are still usable. However, because the diameters of these old rollers are different from the winding rollers on the winding device, they cannot be directly installed on the winding device, leading to ineffective utilization and resource waste. Therefore, there is an urgent need for a winding device that can accommodate rollers of different diameters. Utility Model Content

[0003] The purpose of this invention is to provide a winding device for a solventless laminating machine that can solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides a winding device for a solventless laminating machine, comprising:

[0005] The take-up roller is capable of rotating about its axis;

[0006] A roller and a limiting cylinder are sleeved on the take-up roller. Two limiting cylinders are symmetrically arranged and are detachably connected to the take-up roller.

[0007] The roller is located between the two limiting cylinders. The inner diameter of the roller is larger than the outer diameter of the take-up roller, forming a gap. The limiting cylinder has a tapered portion at one end near the roller. The diameter of the tapered portion gradually decreases towards the roller. A portion of the tapered portion extends into the gap, and its outer wall is tightly fitted with the inner wall of the roller.

[0008] Optionally, a limiting block is provided on the outer wall of the tapered portion, and a limiting groove that cooperates with the limiting block is provided on the inner wall of the roller.

[0009] Optionally, at least two limiting blocks are provided at circumferential intervals along the tapered portion.

[0010] Optionally, it also includes a fastener, wherein the limiting cylinder is provided with a through hole opened radially thereon, the take-up roller is provided with a threaded hole corresponding to the through hole, and the fastener passes through the through hole and is threadedly connected to the threaded hole.

[0011] Optionally, a plurality of threaded holes are provided at intervals along the axial direction of the take-up roller.

[0012] Optionally, the fastener is a bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting a tapered part on the limiting cylinder to limit the roller, the stability of the roller during operation is ensured, and the roller is prevented from shifting or shaking during the winding process. In addition, the tapered part can adapt to the installation of rollers with different inner diameters, which is highly adaptable, and is easy to disassemble and assemble. It can also reuse waste rollers and save costs. Attached Figure Description

[0028] like Figures 1 to 4 As shown, this utility model embodiment provides a winding device for a solventless laminating machine, including a winding roller 100, a roller 200, a limiting cylinder 300, and a fastener 400.

[0029] The take-up roller 100 is rotatable around its axis. Specifically, both ends of the take-up roller 100 are rotatably mounted on the solventless laminating machine via bearing seats.

[0030] Roller 200 and limiting cylinder 300 are both sleeved on take-up roller 100. Specifically, there are two symmetrically arranged limiting cylinders 300, which are detachably connected to take-up roller 100.

[0031] Furthermore, the roller 200 is located between the two limiting cylinders 300. The inner diameter of the roller 200 is larger than the outer diameter of the take-up roller 100, forming a gap. A tapered portion 310 is provided at one end of the limiting cylinder 300 near the roller 200. Specifically, the diameter of the tapered portion 310 gradually decreases towards the roller 200. A portion of the tapered portion 310 extends into the gap, and its outer wall is tightly fitted with the inner wall of the roller 200, thereby limiting the roller 200 and ensuring the stability of the roller 200 during operation. This prevents the roller 200 from shifting or shaking during the take-up process. The tapered portion 310 can adapt to the installation of rollers 200 with different inner diameters, has high adaptability, is easy to disassemble and assemble, and can reuse discarded rollers 200, saving costs.

[0032] In one embodiment, a limiting block 320 is protruding from the outer wall of the tapered portion 310, and a limiting groove 210 that cooperates with the limiting block 320 is provided on the inner wall of the roller 200. Specifically, at least two limiting blocks 320 are provided at intervals along the circumference of the tapered portion 310. The provision of the limiting block 320 and the limiting groove 210 can further improve the stability of the roller 200 during operation, avoid local wear, and extend the service life of the limiting cylinder 300.

[0033] In one embodiment, the limiting cylinder 300 is provided with a through hole 330 opened radially therein, and the take-up roller 100 is provided with a threaded hole 110 corresponding to the through hole 330. The fastener 400 passes through the through hole 330 and is threadedly connected to the threaded hole 110, which is convenient for disassembly and assembly. Furthermore, multiple threaded holes 110 are provided at intervals along the axial direction of the take-up roller 100 to facilitate adjustment of the limiting cylinder 300 to adapt to rollers 200 with different inner diameters or lengths. Specifically, the fastener 400 is preferably a bolt.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
