Description

Technical Field

[0001] This utility model relates to the field of multi-layer laminator technology, and more specifically to a multi-layer transmission structure. Background Technology

[0002] In modern industrial production, laminators are crucial equipment widely used in the lamination of various materials. While traditional laminators can meet basic lamination requirements, they suffer from several limitations in practical applications, such as large footprint, low output, and complex structure. With continuous advancements in industrial technology and the increasing demand for higher production efficiency, multi-layer laminators have emerged. Multi-layer laminators, with their significant advantages such as small footprint, high output, and compact structure, have gradually become the mainstream choice in the industry.

[0003] However, in practical use, the transfer of components between layers in multilayer laminators has gradually become a key factor restricting their performance. Specifically, the relatively small structural space of multilayer laminators necessitates the separation of the upper and lower fabrics after the laminator is opened, and existing separation methods are often inefficient and prone to failure. Furthermore, the transfer structure needs to have tensioning capabilities to ensure the high-temperature fabric remains flat during transfer and prevents wrinkles. Wrinkles in the high-temperature fabric not only affect the product's appearance quality but can also lead to air bubbles or other defects during lamination, thereby reducing the overall performance of the product.

[0004] Another pressing issue is the tendency for high-temperature fabric to skip teeth during transport. This skipping leads to unstable transport of the fabric, impacting production efficiency and product quality. Existing transport structures are significantly inadequate in preventing skipping, especially in high-temperature, high-speed operating environments where the problem is more pronounced.

[0005] Furthermore, the flattening of the high-temperature fabric is a crucial step in the operation of multi-layer laminators. Because the high-temperature fabric is easily deformed or wrinkled by external forces during transport, an effective flattening device is needed to ensure that the fabric remains flat before entering the lamination chamber. However, existing flattening devices have design flaws and cannot fully meet the high-efficiency production requirements of multi-layer laminators.

[0006] In summary, existing multi-layer laminator transmission structures have significant shortcomings in addressing issues such as wrinkling of high-temperature fabric, separation of high-temperature fabric during opening and closing of the cover, transmission tension, and prevention of tooth skipping. These problems not only affect the production efficiency and product quality of multi-layer laminators but also increase equipment maintenance costs and operational complexity. Therefore, developing a novel multi-layer transmission structure that can effectively solve these problems is of paramount practical significance for improving the overall performance of multi-layer laminators and meeting the high-efficiency demands of modern industrial production. Utility Model Content

[0007] In view of this, the present invention provides a multi-layer transmission structure, which aims to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A multi-layer transmission structure includes: a rack, and a multi-layer transmission unit disposed on the rack, the transmission unit comprising:

[0010] A heating plate assembly is provided, and transmission guide rails are installed on both sides of the heating plate assembly.

[0011] A drive roller assembly and a driven tension roller assembly are respectively installed at the front end and rear end of the heating plate assembly. The drive roller assembly and the driven tension roller assembly are connected by a chain drive provided in the transmission guide rail.

[0012] The high-temperature cloth consists of two pieces, arranged end-to-end on the outer sides of the drive roller assembly, the driven tension roller assembly, and the heating plate assembly. The end-to-end gap between the two pieces of high-temperature cloth is connected by a high-temperature cloth connecting assembly, which has a rubber spring for realizing the extension and retraction of the two pieces of high-temperature cloth.

[0013] Through the above technical solution, this utility model, by designing a high-temperature cloth connecting component and a rubber spring, enables the high-temperature cloth to separate vertically when the laminator is opened, avoiding the problems of low efficiency and easy failure of traditional separation methods. The elasticity of the rubber spring effectively buffers the tension changes of the high-temperature cloth during transmission, reducing wrinkles and ensuring that the high-temperature cloth remains flat during transmission. The multi-layer transmission unit design enables the equipment to achieve efficient lamination processing within a limited space, improving the space utilization rate of the equipment and reducing the floor space required. The elasticity of the rubber spring can adapt to high-temperature cloths of different thicknesses and materials, enhancing the versatility and adaptability of the equipment.

[0014] Preferably, in the aforementioned multi-layer transmission structure, the transmission guide rail is fixedly connected to both sides of the heating plate assembly via guide rail connectors. The use of guide rail connectors makes the connection between the transmission guide rail and the heating plate assembly more robust, improving the stability of the entire transmission structure and reducing vibration and deformation that may occur during operation. Fixed connection via guide rail connectors makes the installation and disassembly of the transmission guide rail more convenient, facilitating equipment maintenance and repair, and reducing equipment maintenance costs. A stable connection method ensures the relative positional accuracy between the transmission guide rail and the heating plate assembly, thereby ensuring the accurate trajectory of the high-temperature cloth during transmission and avoiding transmission failures caused by guide rail misalignment.

[0015] Preferably, in the above-mentioned multi-layer transmission structure, the drive roller assembly includes two roller mounting components, each fixed to one side of the heating plate assembly. A drive roller is rotatably connected between the two roller mounting components. A transmission motor is mounted on the outside of one of the roller mounting components via a motor mounting component. The power output end of the transmission motor is connected to the drive roller via a coupling. The drive roller is connected to the driven tension roller assembly via a chain. By driving the drive roller with a motor, and then driving the driven tension roller assembly via a chain, efficient power transmission is achieved, ensuring stable transmission of the high-temperature fabric. The use of a motor allows for more precise and flexible control of transmission speed and tension, which can be adjusted according to different production needs, improving the automation level of the equipment. The design of the roller mounting components makes the installation of the drive roller more stable, while also facilitating the installation and adjustment of the motor. The overall structure is compact and reasonable, improving the reliability and service life of the equipment.

[0016] Preferably, in the above-described multi-layer transmission structure, the end of the drive roller is connected to the roller mounting component via a first mounted bearing, and the end of the drive roller is connected to a drive sprocket for engagement with the chain. The engagement of the drive sprocket and the chain enables precise transmission, reduces energy loss during transmission, and improves transmission efficiency. The use of the first mounted bearing effectively supports the drive roller, ensuring its stability during operation, reducing vibration and wear, and extending the service life of the equipment. The mounted bearing design makes bearing replacement and maintenance more convenient, reducing the difficulty and cost of equipment maintenance.

[0017] Preferably, in the above-mentioned multi-layer transmission structure, the driven tensioning roller assembly includes two driven roller mounting components, which are respectively fixed to both sides of the heating plate assembly. A driven flattening roller is rotatably connected between the two roller mounting components via a second seated bearing. A driven sprocket is connected to the driven flattening roller via a bearing. A chain tensioning block is mounted on the second seated bearing, and a chain anti-skip tooth block is mounted on the chain tensioning block. The driven sprocket is drive-connected to the driving sprocket. The design of the chain tensioning block and the chain anti-skip tooth block effectively prevents chain skipping during operation, improving the stability and reliability of the equipment. The driven flattening roller can flatten the high-temperature fabric, reducing wrinkles and ensuring that the high-temperature fabric remains flat before entering the lamination chamber, improving product quality. The use of the driven roller mounting components and seated bearings makes the installation of the driven flattening roller more stable, while facilitating the connection and adjustment of the driven sprocket, optimizing the structure of the entire driven tensioning roller assembly.

[0018] Preferably, in the aforementioned multi-layer transmission structure, the driven flattening roller is thicker in the middle and thinner at both ends. This design allows for better flattening of the high-temperature fabric. By changing the diameter difference of the flattening rollers, wrinkles are more effectively eliminated as the high-temperature fabric passes through them, improving the flattening effect. This structure can be adjusted according to high-temperature fabrics of different thicknesses and materials, enhancing the equipment's adaptability to different materials and improving its versatility. The thicker-in-the-middle, thinner-at-the-ends design also ensures more uniform stress on the high-temperature fabric during flattening, reducing wear between the flattening roller and the fabric and extending the service life of the flattening roller.

[0019] Preferably, in the aforementioned multi-layer transmission structure, the surface of the driven flattening roller has outwardly extending guide patterns. These guide patterns guide the high-temperature fabric to run smoothly on the surface of the flattening roller, further reducing wrinkles and improving the flattening effect of the high-temperature fabric. The guide patterns also increase the friction between the flattening roller and the high-temperature fabric, making the fabric more stable during transmission, reducing slippage, and improving the stability of the equipment operation. Through the design of the guide patterns, it is possible to effectively prevent the high-temperature fabric from shifting or wrinkling during the flattening process, thereby improving the product's appearance quality and overall performance.

[0020] Preferably, in the above-mentioned multi-layer transmission structure, the high-temperature cloth connecting assembly further includes a high-temperature cloth pressure plate and a high-temperature cloth rod. The high-temperature cloth pressure plate is fastened to one end of one piece of high-temperature cloth, and the high-temperature cloth rod is connected to one end of another piece of high-temperature cloth. Multiple rubber springs are included, with one end connected to the high-temperature cloth rod and the other end rotatably connected to the high-temperature cloth pressure plate via a pin. The design of the high-temperature cloth pressure plate and high-temperature cloth rod securely fixes the high-temperature cloth to the connecting assembly, ensuring that the high-temperature cloth will not loosen or fall off during transmission, thus improving the stability of the connection. The rotatable connection of the rubber springs to the high-temperature cloth pressure plate via pins allows the high-temperature cloth to move flexibly during transmission, better adapting to the operating conditions of the equipment and reducing wrinkles. This connection method makes the installation and adjustment of the high-temperature cloth more convenient, allowing for quick adjustments according to actual needs and improving the operating efficiency of the equipment.

[0021] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a multi-layer transmission structure, which has the following beneficial effects:

[0022] 1. Improved Transmission Stability and Reliability: The chain tensioning block and anti-skid block design in the driven tensioning roller assembly effectively prevents chain skipping during operation, improving equipment stability. The special structure of the driven flattening roller (thick in the middle and thin at both ends, with guide patterns on the surface) effectively flattens the high-temperature fabric, reducing wrinkles and ensuring the fabric remains flat during transmission, thus avoiding product defects caused by wrinkles. The rubber spring design in the high-temperature fabric connecting assembly allows for the expansion and contraction of the fabric, buffering tension changes during transmission, further reducing wrinkles and improving transmission stability.

[0023] 2. Optimized Equipment Structure and Performance: The multi-layer transmission unit's structural design enables efficient lamination processing within a limited space, significantly reducing floor space and improving space utilization. The chain drive connection between the drive roller assembly and the driven tension roller assembly, combined with the motor drive and the active sprocket, achieves efficient power transmission while facilitating precise speed and tension control. The transmission guide rail is fixedly connected to the heating plate via guide rail connectors, and the driven flattening roller is mounted using seated bearings, resulting in a more stable overall structure, reducing vibration and wear during operation, and extending the equipment's service life.

[0024] 3. Enhanced adaptability and versatility: The driven flattening roller's thicker middle and thinner side structure, along with its guide pattern design, allows it to adapt to high-temperature fabrics of varying thicknesses and materials, enhancing the equipment's versatility. The design of the high-temperature fabric connecting components makes installation and adjustment of the fabric more convenient, and the elasticity of the rubber springs can accommodate different tension requirements, improving the equipment's versatility and flexibility.

[0025] 4. Reduced equipment maintenance costs: The design of guide rail connectors and seated bearings makes equipment installation and disassembly more convenient, reducing maintenance time and difficulty. Optimized structural design (such as preventing tooth skipping and flattening) reduces the failure rate during equipment operation, thus lowering maintenance costs.

[0026] 5. Improved Product Quality: Through flattening and tension control, the high-temperature fabric remains flat during transport, avoiding lamination defects caused by wrinkles or skipped teeth, thus significantly improving the product's appearance quality and overall performance. Equipment operation is more stable, reducing downtime due to malfunctions or adjustments and increasing production efficiency.

[0027] 6. Meeting the high-efficiency requirements of modern industrial production: The combination of motor drive and chain drive enables precise control of transmission speed and tension, improving the automation level of the equipment and meeting the requirements of modern industrial production for high efficiency, stability, and high quality. The equipment is designed to adapt to various materials and process requirements, has wide applicability, and can better meet the production needs of different users. Attached Figure Description
