Detailed Implementation

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0016] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0018] Please see Figures 1 to 5 This invention provides a polypropylene sheet lamination and cooling device according to one embodiment of the present invention, which includes a lamination assembly 10 and a cooling assembly 20 installed at one end of the lamination assembly 10.

[0019] The laminating assembly 10 includes a frame 11, a fixed pressure roller 12 fixedly installed inside the frame 11, a movable pressure roller 13 that can be lifted and lowered inside the frame 11, and a motor 14 installed on one side of the frame 11. The motor 14 is used to drive the movable pressure roller 13 to rotate.

[0020] The fixed pressure roller 12 and the movable pressure roller 13 are arranged opposite each other, with their axes parallel and the distance between them adjustable. A pressing space is formed between the fixed pressure roller 12 and the movable pressure roller 13. This pressing space is used to extrude and shape the polypropylene sheet to ensure that the sheet reaches the preset thickness and flatness.

[0021] In this embodiment, as Figure 3 and Figure 4 As shown, bearings 15 are connected to opposite ends of the movable pressure roller 13. The opposite sides of the bearings 15 are slidably connected to the inner wall of the frame 11 via guide rail pairs 16. The guide rail pairs 16 are arranged vertically to guide the lifting and lowering movement of the movable pressure roller 13, ensuring its movement accuracy. Furthermore, a lifting cylinder 17 is connected below the bearings 15. Through the action of the lifting cylinder 17, the movable pressure roller 13 can be driven to steadily lift and lower along the guide rail pairs 16 within the frame 11, thereby precisely adjusting the gap of the pressing space to adapt to the processing requirements of sheets of different thicknesses.

[0022] Please refer to it again. Figure 1 One end of the fixed pressure roller 12 is coaxially connected to a driven wheel 18, and the motor 14 is connected to a driving wheel (not shown). The driving wheel and the driven wheel are connected by a synchronous belt, thereby realizing the transmission connection between the motor 14 and the fixed pressure roller 12. During operation, the motor 14 drives the fixed pressure roller 12 to rotate. The fixed pressure roller 12 drives the movable pressure roller 13 to rotate synchronously in the opposite direction through the friction between the sheet and the movable pressure roller 13, ensuring that the sheet is smoothly conveyed in the pressing space.

[0023] The cooling assembly 20 includes a support frame 21 installed at one end of the bracket 11, a crossbeam 22 connected to the top of the support frame 21, a plurality of jet nozzles 23 evenly spaced on the bottom surface of the crossbeam 22, and air pipe connectors 24 installed at opposite ends of the crossbeam 22; the air pipe connectors 24 are used to connect to a cold air supply system, and the cooling airflow is transported through the interior of the crossbeam 22 to the jet nozzles 23 and then sprayed downwards.

[0024] In this embodiment, the air nozzle 23 is located above the lamination space, and the air outlet direction of the air nozzle 23 is perpendicular to the sheet conveying path, covering the entire width of the sheet. The cooling airflow ejected by the air nozzle 23 acts on the surface of the sheet. By adjusting parameters such as the temperature and unit flow rate of the cooling airflow, the laminated sheet can be efficiently cooled in a targeted manner, meeting the cooling requirements of sheets of different specifications and processing speeds. Compared with traditional water cooling methods, this invention uses air cooling to exchange heat with the laminated sheet, eliminating the need for cooling water consumption. This not only significantly reduces the operating costs of the equipment but also avoids problems such as scale formation and pipe corrosion, reducing maintenance frequency and costs.

[0025] like Figure 5 As shown, the interior of the crossbeam 22 is provided with an air duct 25 along its length. The air duct 25 is a through cavity structure. The top of the jet nozzle 23 is connected to the interior of the air duct 25. The two ends of the air duct 25 are respectively connected to the cold air supply system through the air pipe joint 24 to ensure that the cooling airflow can be evenly distributed to each jet nozzle 23, and to ensure the consistency of the cooling effect in each area of ​​the sheet.

[0026] In this embodiment, the air nozzle 23 is arranged vertically, and the air outlet of the air nozzle 23 is directly facing the upper surface of the sheet, which can maximize the contact efficiency between the cooling airflow and the sheet and improve the heat exchange rate.

[0027] The aforementioned polypropylene sheet lamination and cooling device has a simple structure and is easy to use. It achieves precise lamination of the sheet by using a fixed pressure roller 12 and a movable pressure roller 13, and uses multiple air nozzles 23 to spray cooling airflow to efficiently cool the laminated sheet. This eliminates the need for the large amount of water required by traditional water cooling, effectively reducing the operating and maintenance costs of the equipment, while improving the controllability of the cooling process and the stability of the sheet quality.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
