Description

Technical Field

[0001] This utility model relates to a roller structure for tape coating, belonging to the field of roller cooling technology. Background Technology

[0002] In the coating process, after the substrate is coated with adhesive or a coating layer by the coating roller, it needs to be rapidly cooled and cured by a cooling roller to prevent the coating from dripping or sticking, ensuring the uniformity of the coating thickness and the flatness of the substrate. The fitting accuracy and adaptability of the cooling roller directly affect the quality of the final product. With the diversification of coating processes, production lines need to accommodate coating rollers of different widths and diameters, and the corresponding installation heights of the coating rollers vary (common height range 50-150cm). This requires the cooling roller to have flexible height adjustment capabilities to achieve precise fitting with coating rollers of different specifications.

[0003] For example, Chinese patent CN209997884U proposes a cooling roller for coating. A translation component allows for easy adjustment of the translational freedom of the roller body to fit and separate from the coating roller. Cooling is achieved through the cooling component; since the roller body is in contact with the coating roller, heat exchange occurs through cooling water. Simultaneously, the coolant and thermally conductive fibers inside the reagent cylinder transfer heat, thereby reducing the temperature of the coating roller and achieving a cooling effect. However, this cooling roller design has significant structural defects: the cooling roller can only achieve horizontal translational adjustment, and its installation height is fixed and cannot be adjusted. It can only accommodate coating rollers of a single height specification. In actual production scenarios, when the production line changes to coating rollers of different diameters and installation heights, the cooling roller cannot accurately fit the new specification coating roller due to its height inability to be adjusted. Either the gap is too large, resulting in low cooling efficiency, or the gap is too small, causing damage to the substrate due to compression. There is an urgent need for a roller structure for tape coating to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a roller structure for tape coating, thereby solving the problems mentioned in the background section. This invention can not only move horizontally, but also make precise height adjustments according to coating rollers with different installation heights, thus providing a good cooling effect, and is compatible with coating rollers of various height specifications.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a roller structure for tape coating, comprising a support plate and a gear transmission seat. First bearing seats are bolted into the front and rear sides of the upper end of the support plate. A threaded adjusting rod is installed through the two first bearing seats. A welding block is welded to the lower end of the gear transmission seat. Multiple guide wheels are installed on the left and right sides of the lower end of the gear transmission seat. A transmission shaft is horizontally mounted inside the lower end of the gear transmission seat via bearings. Two first bevel gears are mounted externally on the transmission shaft. Driven threaded rods are longitudinally mounted inside the left and right ends of the gear transmission seat via bearings. Each driven screw is equipped with a second bevel gear at its lower end. The two second bevel gears mesh with the two first bevel gears respectively. The two driven screws are threaded with internal threaded rings. The upper ends of the two internal threaded rings are longitudinally equipped with guide rods. Multiple guide rods slide through the left and right sides of the upper end of the gear transmission seat, and the upper ends of the multiple guide rods are connected to two adjusting seats respectively. The upper ends of the two adjusting seats are equipped with deep groove ball bearing seats. Water pipes are installed through the two deep groove ball bearing seats. Cooling roller bodies are coaxially installed between the two water pipes. The cooling roller bodies are provided with a copper-nickel alloy heat-conducting layer and spiral guide ribs inside.

[0006] Furthermore, support blocks are installed around the lower perimeter of the support plate.

[0007] Furthermore, a first knob is installed at the front end of the threaded adjustment rod.

[0008] Furthermore, the threaded adjusting rod passes through the welded block via a thread.

[0009] Furthermore, guide grooves are provided on both the left and right sides of the upper end of the support plate, and multiple guide wheels are slidably located at the two guide grooves respectively.

[0010] Furthermore, a second knob is installed on the left end of the drive shaft.

[0011] Furthermore, the water supply pipe on the left is connected to an external water supply pipe, and the water supply pipe on the right is connected to an external return water pipe.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a roller structure for tape coating.

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1-6This utility model provides a technical solution: a roller structure for tape coating, including a support plate 2 and a gear transmission seat 9. First bearing seats 3 are bolted into the front and rear sides of the upper end of the support plate 2. A threaded adjusting rod 5 is installed between the two first bearing seats 3. A welding block 6 is welded to the lower end of the gear transmission seat 9. Multiple guide wheels 8 are installed on the left and right sides of the lower end of the gear transmission seat 9. A transmission shaft 11 is horizontally mounted inside the lower end of the gear transmission seat 9 via bearings. Two first bevel gears 12 are mounted outside the transmission shaft 11. Driven threaded rods 14 are longitudinally mounted inside the left and right ends of the gear transmission seat 9 via bearings. Second bevel gears 13 are mounted at the lower ends of the two driven threaded rods 14, and the two second bevel gears 13 mesh with the two first bevel gears 12 respectively. An inner threaded ring 15 is installed via a thread. Guide rods 16 are longitudinally installed around the upper circumference of both inner threaded rings 15. Multiple guide rods 16 slide through the left and right sides of the upper end of the gear transmission seat 9, and the upper ends of multiple guide rods 16 are connected to two adjusting seats 17. Deep groove ball bearing seats 18 are installed on the upper end of both adjusting seats 17. Water pipes 19 are installed through both deep groove ball bearing seats 18. Cooling roller body 20 is coaxially installed between the two water pipes 19. The cooling roller body 20 is provided with a copper-nickel alloy heat-conducting layer 21 and a spiral guide rib 22 inside. This design solves the problem that the original coating cooling roller can only achieve horizontal translation adjustment, and its installation height is fixed and cannot be adjusted. It can only be adapted to coating rollers of a single height specification and cannot be fitted and cooled with coating rollers of new specifications.

[0017] In the first embodiment of this utility model: support blocks 1 are installed around the lower perimeter of the support plate 2. The added support blocks 1 are installed around the lower perimeter of the support plate 2, serving as the support feet for the entire device. Their main function is to elevate and stabilize the support plate 2, ensuring sufficient space at the bottom of the device and preventing corrosion or instability that may result from direct contact with the ground.

[0018] A first knob 4 is installed at the front end of the thread adjustment rod 5, and is fixed to the front end of the thread adjustment rod 5 by adding the first knob 4. As a drive handle for horizontal adjustment, the operator can easily drive the thread adjustment rod 5 to rotate by manually rotating the first knob 4, thereby driving the entire gear transmission seat 9 and the cooling roller body 20 above it to move in the front and back direction, so as to realize the horizontal alignment and disengagement of the cooling roller body 20 and the coating roller.

[0019] The threaded adjusting rod 5 passes through the welding block 6 via a thread. When the threaded adjusting rod 5 rotates, its axial position is fixed by the first bearing seat 3. Therefore, the welding block 6, which meshes with it via a thread, will cause the entire gear transmission seat 9 to move horizontally in a straight line along the axial direction of the threaded adjusting rod 5.

[0020] The upper left and right sides of the support plate 2 are provided with guide grooves 7. Multiple guide wheels 8 are slidably located at the two guide grooves 7 respectively. The guide grooves 7 are provided on the upper left and right sides of the support plate 2. The guide wheels 8 are installed on the lower left and right sides of the gear transmission seat 9. The wheel body is embedded in the guide groove 7 and can roll freely. It can limit the horizontal movement trajectory of the gear transmission seat 9 and ensure that it moves along the axis of the coating roller, avoiding deviation that would cause uneven contact between the cooling roller body 20 and the coating roller.

[0021] A second knob 10 is installed at the left end of the drive shaft 11, and is fixed to the left end of the drive shaft 11 by the added second knob 10. It serves as a drive handle for height adjustment. The operator manually rotates the second knob 10 to drive the drive shaft 11 and the first bevel gear 12 to rotate, which in turn drives the driven screw 14 to rotate through the bevel gear pair, ultimately realizing the vertical lifting and lowering of the cooling roller body 20.

[0022] The left water supply pipe 19 connects to an external water supply pipe, and the right water supply pipe 19 connects to an external return water pipe. The added left water supply pipe 19 serves as the inlet, connecting to an external cooling water source such as a chilled water unit via the external water supply pipe, thus introducing the cooling medium into the cooling roller body 20. The right water supply pipe 19 serves as the outlet / return outlet, exporting the cooled medium that has absorbed heat back to the external circulating cooling system. This split design facilitates pipe connection and sealing.

[0023] As a second embodiment of this utility model: the entire device is placed below or to the side of the coating roller in the coating production line. The operator rotates the first knob 4, driving the thread adjustment rod 5 to rotate. Through threaded transmission, the welding block 6 drives the gear transmission seat 9 to move smoothly forward or backward along the guide groove 7 on the support plate 2. When the cooling roller body 20 moves horizontally to a position approximately aligned with the target coating roller, the first knob 4 is stopped. Then the operator rotates the second knob 10, driving the transmission shaft 11 to rotate. The transmission shaft 11 drives the two first bevel gears 12 on it to rotate synchronously. The first bevel gears 12 mesh with the second bevel gears 13, converting the horizontal rotational motion into the vertical rotational motion of the two driven thread rods 14. The rotation of the driven thread rods 14 drives the internal threaded ring 15, which is threaded with it, to make a vertical linear motion. The internal threaded ring 15 drives the upper adjustment seat 17 and the deep groove ball bearing seat 18 to move vertically synchronously through multiple guide rods 16 (which serve as guides and anti-rotation). Finally, the cooling roller body 20, installed between the two deep groove ball bearing seats 18, is precisely adjusted to the required working distance from the coating roller, typically in slight contact or maintaining a small gap.

[0024] The deep groove ball bearing housing 18 allows the water supply pipe 19 and the cooling roller body 20 to rotate freely during adjustment and operation. When the external cooling water system is activated, cooling water enters the cooling roller body 20 from the left water supply pipe 19. The cooling water flows through the flow channel formed by the spiral guide ribs 22; this design extends the water flow path, improves heat exchange efficiency, and ensures uniform roller surface temperature. After carrying away the heat transferred from the copper-nickel alloy heat-conducting layer 21, the water flows out from the right water supply pipe 19 and returns to the cooling system for cooling circulation. The high-temperature coating roller transfers heat to the cooling roller through contact or radiation with the surface of the cooling roller body 20, thus achieving continuous and effective cooling of the coating roller. When it is necessary to change to a coating roller with a different diameter (i.e., a different center height), simply rotate the second knob 10 in the opposite direction to lower the cooling roller body 20, and then rotate the first knob 4 to move it horizontally out of the working area. Once the new coating roller is in place, repeat the above steps to readjust the level and height, and you can quickly adapt it to the new specification of coating roller.
