Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically a cooling device for aluminum plate hot coating equipment. Background Technology

[0002] In the field of evaporation plate processing, hot melt adhesive film needs to be applied to the surface of aluminum plates to improve surface quality and adhesion during vulcanization bonding, while also enhancing aesthetics. Currently, many aluminum plate manufacturing plants apply film to the surface of aluminum plates. However, existing equipment can only apply film to one side of the plate. Furthermore, current aluminum plate hot-lamination equipment either immerses the plate in water for cooling after lamination or directly feeds it into a punch press for cutting, lacking a corresponding cooling device. This leads to quality defects such as delamination and blistering between the lamination plate and the hot melt adhesive film, affecting production quality. Therefore, a cooling device for hot-lamination equipment needs to be designed.

[0003] A cooling device for an aluminum sheet hot-coating equipment, Chinese patent document number CN213648345U, includes a base plate and a heat-conducting plate arranged at an angle relative to the horizontal plane. The upper end of the heat-conducting plate serves as an inlet, and the lower end serves as an outlet. The heat-conducting plate receives the coated aluminum sheet from the hot-coating equipment and allows it to slide from the inlet to the outlet. A heat dissipation pipe is also provided below the heat-conducting plate, with one end serving as a liquid inlet and the other end as a liquid outlet, allowing coolant to flow from the inlet to the outlet. This invention utilizes the heat-conducting plate to receive the coated aluminum sheet from the hot-coating equipment, allowing it to slide from the inlet to the outlet. The heat-conducting plate and heat dissipation pipe cool the coated aluminum sheet, ensuring the film on the surface of the sheet completely solidifies and adheres to the aluminum sheet. This effectively prevents delamination and blistering of the coated aluminum sheet, improving the production quality of the coated aluminum sheet.

[0004] However, it has the following drawbacks: First, the cooling device is too long, which increases the length of the entire equipment; second, it relies entirely on cooling to condense the film and adhere it to the aluminum plate, which is relatively slow. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for aluminum plate hot-coating equipment to solve the problems existing in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for aluminum plate hot coating equipment, comprising a cooling copper tube 7, characterized in that: the cooling copper tube 7 is wound and fixed around the outer ring of a condensing main shaft 9, and a condensing roller 8 is circumferentially tangent to the condensing main shaft 9; rotating shafts 10 are provided on both sides of the condensing main shaft 9, and the shaft center of the rotating shaft 10 is respectively provided with an inlet pipe 3 and an outlet pipe 12, which are connected to the cooling copper tube 7 through a connecting pipe 6; the rotating shaft 10 is supported on a support base 1 by a bearing 4, and is driven by a motor 14 below the support base 1.

[0007] Furthermore, the two sides of the rotating shaft 10 are connected to the inlet pipe 3 and the outlet pipe 12 respectively through the rotating pipe joint 2.

[0008] Furthermore, the output end of the motor 14 is connected to a small synchronous pulley 15, and is connected to a large synchronous pulley 11 on the same side of the rotating shaft 10 via a synchronous belt 13.

[0009] Furthermore, the condensing spindle 9 is provided with caps 5 on both sides, which are equal in diameter to the inner diameter of the condensing roller 8.

[0010] This invention has the following advantages: First, cooling the aluminum plate by using a condensing roller improves the cooling speed and the efficiency of film adhesion on the aluminum plate; second, cooling by a condensing roller shortens the overall length of the machine and reduces the floor space required.

[0014] Please see Figure 1This utility model provides a technical solution: a cooling device for aluminum plate hot coating equipment, including a cooling copper pipe 7, which is wound and fixed around the outer ring of a condensing main shaft 9, and a condensing roller 8 is tangent to the condensing main shaft 9. Rotating shafts 10 are provided on both sides of the condensing main shaft 9. The rotating shafts 10 are supported on the support base 1 by bearings 4, and a large synchronous pulley 11 is provided at one end. A motor 14 is provided below the support base 1 on the same side. The output end of the motor 14 is connected to a small synchronous pulley 15, which is connected to the large synchronous pulley 11 through a synchronous belt 13.
