Description

Technical Field

[0001] This utility model relates to the field of film laminating equipment technology, specifically to a mold roller limiting structure for a film laminating equipment. Background Technology

[0002] Film laminators are key equipment in the field of film material processing, primarily used to firmly bond film materials with different properties (such as plastic film, aluminum foil, and paper) into multi-layer structures through physical or chemical methods. In modern packaging, electronics, and building materials industries, film laminators play a crucial role in enhancing the functionality, durability, and aesthetics of materials. This equipment achieves continuous film conveying and lamination through a precise mechanical transmission system, maintaining stable lamination quality on high-speed production lines. With the expansion of composite material applications, film laminators have evolved from single-material lamination to supporting multi-layer stacking of various materials (such as barrier films, conductive films, and decorative films), meeting diverse needs such as oxygen barrier preservation in food packaging, shielding and protection for electronic products, and thermal and sound insulation in building curtain walls. The integration of intelligent manufacturing technology enables film laminators to have online monitoring and process adjustment capabilities, allowing real-time detection of key parameters such as lamination strength and film tension, and automatic optimization of production parameters. Increasing environmental requirements have driven the development of equipment towards low energy consumption and low waste; some models use hot melt adhesives or solvent-free adhesives to replace traditional solvent-based glues, significantly reducing VOC emissions. The performance of laminators directly affects the interlayer bonding strength, smoothness, and production efficiency of composite materials. High-precision laminators can reduce material waste, avoid defects such as bubbles and wrinkles, and ensure the adaptability of finished products in subsequent slitting, bag making, or molding processes. They are an important piece of equipment supporting the upgrading of the functional film materials industry.

[0003] However, laminating machines suffer from a significant problem in actual production: the inconvenience of disassembling the mold rollers. Existing equipment typically uses complex bolt fixings, requiring multiple fasteners to be loosened sequentially, followed by the use of specialized tools to tap or pry the rollers apart. This process is cumbersome and time-consuming, especially on production lines where mold rollers need frequent replacement, significantly increasing equipment downtime. In some models, space constraints make it difficult for operators to access internal fasteners, further extending the disassembly and assembly cycle. Frequent, forceful disassembly and assembly can also lead to stripped threads or wear on the positioning surfaces, affecting the installation accuracy of the mold rollers and the stability of the laminating quality. Utility Model Content

[0004] The purpose of this invention is to provide a mold roller limiting structure for a film laminating machine, which solves the problem that the mold roller of the film laminating machine is not convenient to disassemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold roller limiting structure for a film laminating device, comprising a mounting base, a rotating shaft rotatably connected inside the mounting base, a roller fixedly connected to the right end of the rotating shaft, a retaining ring fixedly connected to the outer side of the rotating shaft, the retaining ring contacting the mounting base, a limiting seat contacting the upper end of the mounting base, the limiting seat rotatably connected to the rotating shaft, the limiting seat contacting the retaining ring, a sliding rod fixedly connected to the lower end of the limiting seat, the sliding rod slidably connected to the mounting base, a limiting ring fixedly connected inside the mounting base, a spring provided on the outer side of the sliding rod, and an adjusting mechanism provided on the mounting base.

[0006] Preferably, the limiting ring contacts the limiting seat, and the limiting ring is slidably connected to the slide rod. Through the design of the limiting ring, the slide rod can be limited.

[0007] Preferably, one end of the spring contacts the slide rod, and the other end of the spring contacts the limiting ring. Through the design of the spring, the limiting seat can be driven to limit the rotation shaft.

[0008] Preferably, the adjusting mechanism includes a threaded rod, the lower end of the mounting base is fixedly connected to the threaded rod, the outer side of the threaded rod is slidably connected to a base, the inner side of the base is rotatably connected to a limit block, the limit block is slidably connected to the threaded rod, the upper end of the limit block is fixedly connected to a limit sleeve, the lower end of the mounting base is fixedly connected to a connecting rod, the connecting rod is slidably connected to the base, the outer side of the connecting rod is fixedly connected to a guide block, and the inner side of the base is fixedly connected to a guide rod. Through the design of the adjusting mechanism, the height of the roller can be adjusted.

[0009] Preferably, a protrusion is fixedly connected to the outer side of the limiting block, and the protrusion is slidably connected to the base. Through the design of the protrusion, the limiting block can play a limiting role.

[0010] Preferably, the limiting sleeve contacts the base, the limiting sleeve contacts the mounting base, and the limiting sleeve is connected to the threaded rod by a thread. Through the design of the limiting sleeve, the position of the threaded rod can be adjusted.

[0011] Preferably, the guide block is slidably connected to the base and slidably connected to the guide rod. The design of the guide block can guide the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting components such as a retaining ring, a limiting seat, and a spring, allows the limiting seat to be moved so that it no longer contacts the rotating shaft and the retaining ring, thereby releasing the restriction on the rotating shaft and enabling the roller to be disassembled. This solves the problem that the mold roller of the film laminating machine is not convenient to disassemble.

[0013] 2. This utility model adds a height adjustment mechanism consisting of a threaded rod and a limiting sleeve. Rotating the limiting sleeve drives the threaded rod to move axially, thereby raising and lowering the mounting base and achieving precise adjustment of the roller height. This design allows the roller to adaptively adjust its position during winding, ensuring close contact with the material and improving winding flatness. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4A mold roller limiting structure for a film laminator includes a mounting base 1. A rotating shaft 2 is rotatably connected inside the mounting base 1. A roller 21 is fixedly connected to the right end of the rotating shaft 2. A retaining ring 22 is fixedly connected to the outside of the rotating shaft 2, and the retaining ring 22 contacts the mounting base 1. The upper end of the mounting base 1 contacts a limiting seat 23, which is rotatably connected to the rotating shaft 2 and contacts the retaining ring 22. A sliding rod 24 is fixedly connected to the lower end of the limiting seat 23, and the sliding rod 24 is slidably connected to the mounting base 1. The mounting base 1 is internally fixedly connected to a limiting ring 25, which contacts a limiting seat 23. The limiting ring 25 is slidably connected to a slide rod 24. The limiting ring 25 is designed to limit the slide rod 24. A spring 26 is provided on the outside of the slide rod 24. One end of the spring 26 contacts the slide rod 24, and the other end of the spring 26 contacts the limiting ring 25. The spring 26 is designed to drive the limiting seat 23 to limit the rotating shaft 2. An adjustment mechanism 3 is provided on the mounting base 1.

[0018] Please see Figure 2-4 The adjusting mechanism 3 includes a threaded rod 31. The lower end of the mounting base 1 is fixedly connected to the threaded rod 31. The outer side of the threaded rod 31 is slidably connected to the base 32. The inner side of the base 32 is rotatably connected to a limiting block 33. The limiting block 33 is slidably connected to the threaded rod 31. The outer side of the limiting block 33 is fixedly connected to a protrusion 34. The protrusion 34 is slidably connected to the base 32. Through the design of the protrusion 34, the limiting block 33 can be limited. The upper end of the limiting block 33 is fixedly connected to a limiting sleeve 35. The limiting sleeve 35 contacts the base 32 and contacts the mounting base 1.

[0019] Please see Figure 2-4 The limiting sleeve 35 and the threaded rod 31 are connected by threads. The position of the threaded rod 31 can be adjusted by the design of the limiting sleeve 35. The lower end of the mounting base 1 is fixedly connected to the connecting rod 36, which is slidably connected to the base 32. The outer side of the connecting rod 36 is fixedly connected to the guide block 37, and the inner side of the base 32 is fixedly connected to the guide rod 38. The guide block 37 is slidably connected to the base 32 and the guide rod 38. The design of the guide block 37 can guide the connecting rod 36. The height of the roller 21 can be adjusted by the design of the adjusting mechanism 3.

[0020] The specific implementation process of this utility model is as follows: When in use, by rotating the limiting sleeve 35, the limiting sleeve 35 and the threaded rod 31 will undergo threaded movement, thereby causing the threaded rod 31 to move within the limiting sleeve 35, and causing the threaded rod 31 to drive the mounting seat 1 to move, so that the mounting seat 1 can drive the roller 21 to move through the rotating shaft 2, and the height of the roller 21 can be adjusted. By moving the limiting seat 23 away from the mounting base 1, the limiting seat 23 drives the slide rod 24 to move, causing the slide rod 24 to move within the limiting ring 25. This causes the slide rod 24 to compress the spring 26, preventing the limiting seat 23 from disengaging from the rotating shaft 2 and the retaining ring 22. This releases the limitation on the rotating shaft 2, allowing the roller 21 to be disassembled.
