Description

Technical Field

[0001] This utility model relates to the field of steel film production technology, specifically a combined pressure roller for steel film production. Background Technology

[0002] Modular pressure rollers for steel film production are modular pressure roller systems designed for the processing needs of metal films (such as lithium battery electrodes, color steel roofing sheets, and solar photovoltaic films). Their core feature is their detachable and expandable structure, enabling efficient rolling of steel films of varying widths and thicknesses. Compared to traditional integrated pressure rollers, the modular design significantly improves the flexibility and adaptability of the equipment, making it particularly suitable for multi-specification, small-batch production scenarios.

[0003] A combined pressure roller is required in the production of steel film. Chinese utility model patent CN214527209U discloses a combined pressure roller for steel film production. The rotating shaft has adapters at both ends, rotatably connected to the shaft. Slider blocks are symmetrically arranged at the upper and lower ends of the adapters. The pressure roller body is installed in the middle section of the rotating shaft, and the pressure roller body includes a first pressure roller and a second pressure roller. A first groove is formed on the opposite side of the first and second mounting frames, and symmetrical sliding grooves are formed on the inner wall of the first groove. The adjacent pressure roller bodies can be adjusted appropriately according to actual needs, improving the equipment's usability. The inner wall of the lubricating oil layer has several through holes, which communicate with the outer wall of the roller, reducing friction damage during operation. The length of the pressure roller body can be adjusted according to the specific width of different steel films being produced, making the roller body and steel film dimensions more compatible, improving production quality and expanding its applicability.

[0004] However, during use, since each pressure roller does not have a corresponding limiting structure, the pressure roller may slip due to vibration during the conveying of the steel film, thus affecting the conveying effect of the steel film and failing to meet production requirements. Therefore, a combined pressure roller for steel film production is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a combined pressure roller for steel film production, which has the advantage of improving the stability of steel film conveying. It solves the problem that in the process of using existing pressure rollers, due to the lack of corresponding limiting structures in each pressure roller, the pressure rollers will slip due to vibration during the conveying of steel film, thus affecting the conveying effect of steel film and failing to meet production requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a combined pressure roller for steel film production, comprising a worktable and two support plates fixedly connected to the top of the worktable, wherein a pressing mechanism capable of improving the stability of steel film conveying is provided between the two support plates;

[0007] The pressing mechanism includes a connecting plate slidably connected to the opposite side of two support plates, a pressure roller rotatably connected between the two connecting plates, a transmission gear rotatably connected to the back of the rear support plate, two racks slidably connected to the back of the rear support plate that can drive the connecting plate to move up and down, the transmission gear meshing with the two racks simultaneously, a connecting shaft rotatably connected between the two support plates that can drive the transmission gear to rotate, and a first motor that can drive the connecting shaft fixedly connected to the front of the front support plate.

[0008] Furthermore, there are two pressure rollers, which are evenly distributed between the two support plates.

[0009] Furthermore, a limiting block is fixedly connected between the connecting plate and the rack, and a limiting groove adapted to the limiting block is provided on the support plate.

[0010] Furthermore, mounting plates are fixedly connected to both the front and back of the top of the workbench, and connecting blocks are slidably connected inside the two mounting plates, with a pressure roller rotatably connected between the two connecting blocks.

[0011] Furthermore, both mounting plates have a limiting opening inside that matches the connecting block, and a support spring is fixedly connected between the connecting block and the inner bottom wall of the limiting opening.

[0012] Furthermore, the two mounting plate brackets are rotatably connected to a feeding roller, and a second motor capable of driving the feeding roller is fixedly connected to the back of the mounting plate.

[0013] Furthermore, two fixing plates are fixedly connected to the top of the workbench on the side away from the mounting plate, and two feeding rollers are rotatably connected between the two fixing plates.

[0014] Furthermore, both the front fixed plate and the front mounting plate are rotatably connected to drive wheels, and a drive belt is connected between the two drive wheels.

[0015] Compared with the prior art, this utility model provides a combined pressure roller for steel film production, which has the following beneficial effects:

[0016] 1. The combined pressure roller for steel film production uses a single first motor to drive the connecting shaft and transmission gear, which in turn drives two racks to move synchronously in opposite directions. This controls the synchronous lifting and lowering of the connecting plates and pressure rollers on both sides. This design completely solves the problem of asynchronous and unbalanced pressure adjustment at both ends of the two pressure rollers in traditional equipment, effectively avoiding steel film deviation, wrinkling or damage caused by uneven pressure, and greatly improving the stability of steel film conveying and product quality.

[0017] 2. This combined pressure roller for steel film production, by setting a pressure roller supported by a support spring, can adaptively float up and down according to the thickness of the steel film. This elastic pressing structure can effectively press the steel film at the beginning of feeding, eliminating its internal slack, and providing a flat and tension-stable steel film for the subsequent main pressure roller process. This further ensures the continuity of production and the consistency of products. It solves the problem that in the use of existing pressure rollers, due to the lack of corresponding limiting structures in each pressure roller, the pressure roller will slip due to vibration during the conveying of the steel film, thus affecting the conveying effect of the steel film and failing to meet production requirements.

[0023] 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.

[0024] Please see Figures 1 to 3 This embodiment of a combined pressure roller for steel film production includes a worktable 1 and two support plates 2 fixedly connected to the top of the worktable 1. A pressing mechanism is provided between the two support plates 2 to improve the stability of steel film conveying. The pressing mechanism includes a connecting plate 3 slidably connected to the opposite side of the two support plates 2. A pressure roller 4 is rotatably connected between the two connecting plates 3. A transmission gear 5 is rotatably connected to the back of the back support plate 2. Two racks 6 that can drive the connecting plate 3 to rise and fall are slidably connected to the back of the back support plate 2. The transmission gear 5 meshes with the two racks 6 at the same time. A connecting shaft 7 that can drive the transmission gear 5 to rotate is rotatably connected between the two support plates 2. A first motor 8 that can drive the connecting shaft 7 is fixedly connected to the front of the front support plate 2.

[0025] Specifically, there are two pressure rollers 4, which are evenly distributed between the two support plates 2. A limit block is fixedly connected between the connecting plate 3 and the rack 6. A limit groove 9 adapted to the limit block is provided on the support plate 2.

[0026] It should be noted that the connecting plate 3 and the rack 6 are slidably connected by the limiting block and the limiting groove 9, which provides precise vertical guidance for the lifting and lowering of the pressure roller 4, preventing the pressure roller 4 from shaking or deflecting when under pressure, ensuring the stability of the pressing process and the uniformity of the pressing quality. Since the pressing force is adjustable and the feeding tension is adaptive, the device can adapt to the processing needs of steel films or similar strip materials of different thicknesses and materials, and the versatility and flexibility of the equipment are greatly improved.

[0027] Please see Figure 1 and Figure 4 In this embodiment, mounting plates 10 are fixedly connected to the front and back of the top of the workbench 1. Connecting blocks 13 are slidably connected inside the two mounting plates 10. A pressing roller 11 is rotatably connected between the two connecting blocks 13. A limiting opening 12 adapted to the connecting block 13 is opened inside the two mounting plates 10. A support spring 14 is fixedly connected between the connecting block 13 and the inner bottom wall of the limiting opening 12.

[0028] Specifically, the two mounting plates 10 are rotatably connected to the feeding rollers 15, and the back of the rear mounting plate 10 is fixedly connected to a second motor 16 that can drive the feeding rollers 15.

[0029] Please see Figure 1 In this embodiment, two fixing plates 17 are fixedly connected to the top of the workbench 1 away from the mounting plate 10. Two feeding rollers 18 are rotatably connected between the two fixing plates 17. Both the front fixing plate 17 and the front mounting plate 10 are rotatably connected to drive wheels 19. A drive belt 20 is connected between the two drive wheels 19.

[0030] Specifically, the feeding roller 15 is directly driven by the second motor 16 and is responsible for actively conveying the steel film. More importantly, through the transmission of the drive wheel 19 and the drive belt 20, the power of the feeding roller 15 is synchronously transmitted to the feeding roller 18 at the rear of the production line. This design ensures the strict synchronization of the speed of each conveying component on the entire production line, fundamentally avoiding the stretching, squeezing or accumulation of the steel film caused by asynchronous speed, making the entire production process smoother and more efficient.

[0031] The working principle of the above embodiments is as follows:

[0032] The steel film strip passes between the feeding roller 15 and the pressing roller 11. The elastically supported pressing roller 11, under the action of the support spring 14, presses the steel film onto the feeding roller 15, providing stable feeding friction and initial tension. The steel film then passes between the upper and lower main pressing rollers 4. According to the thickness of the steel film and the process requirements, the first motor 8 is started, which drives the transmission gear 5 to rotate through the connecting shaft 7. The transmission gear 5 drives the two racks 6 to move synchronously in opposite directions, thereby driving the two connecting plates 3 and the pressing rollers 4 they support to adjust to a suitable gap, applying the required rolling pressure to the passing steel film for fine pressing, thickness setting or leveling. The second motor 16 is started, driving the feeding roller 15 to rotate, actively conveying the steel film with the cooperation of the pressing roller 11. At the same time, the power of the feeding roller 15 is synchronously transmitted to the feeding roller 18 in the rear section through the drive wheel 19 and the drive belt 20, so that the feeding roller 18 rotates at the same linear speed, smoothly outputting the pressed steel film.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
