Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to a protective mechanism for a laminating machine. Background Technology

[0002] A laminating machine is a device that protects the surface of materials by covering them with a thin film. It is mainly used in three major fields: agricultural planting, printing surface processing, and industrial precision manufacturing. In agricultural production, it is used to lay mulch to improve the crop growing environment; in the printing industry, it can laminate plastic film onto the surface of paper or board to achieve waterproofing, wear resistance, and other effects; and in the industrial field, it is used for high-precision lamination processing of touch screens, furniture boards, etc.

[0003] During production, laminating machines use multiple gears to transport the tensioned film. However, these gears are exposed and lack protective measures, which can pose a safety hazard to operators around the equipment. On the other hand, completely sealing them would affect heat dissipation between the gears. To solve these problems, a protective mechanism for laminating machines is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the gears on the existing laminating machine are exposed and lack protective measures, while complete sealing will affect the heat dissipation of the gears. Therefore, a protective mechanism for the laminating machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective mechanism for a laminating machine includes a laminating machine body, multiple conveying rollers rotatably mounted on the surface of the laminating machine body, a first gear fixedly mounted on one end of each conveying roller, a rotating shaft rotatably connected to the inner wall of the laminating machine body, a protective box fixedly connected to the surface of the rotating shaft, multiple clearance holes opened on the surface of the protective box, a fixed shaft fixedly connected to the surface of the protective box, and a cooling, cleaning, and positioning structure provided on the upper surface of the laminating machine body.

[0007] Preferably, the cooling and cleaning positioning structure includes a fixed cylinder fixedly connected to the surface of the laminating machine body, a limit block slidably connected to the inner wall of the fixed cylinder, a pull ring fixedly connected to the upper surface of the limit block, the surface of the limit block being adapted to the surface of the fixed shaft, a tray fixedly connected to the surface of the laminating machine body, and the surface of the fixed shaft being adapted to the surface of the tray.

[0008] Furthermore, a spring is fixedly connected to the inner wall of the fixed cylinder, and one end of the spring is fixedly connected to the surface of the limiting block.

[0009] Preferably, a filter screen is fixedly connected to the inner wall of the protective box, a placement plate is fixedly connected to the upper surface of the laminating machine body, a cleaning brush is fixedly connected to the upper surface of the laminating machine body, the cleaning brush is used to clean the surface of the filter screen, and a push-pull plate is fixedly connected to the surface of the protective box.

[0010] Furthermore, a positioning plate is fixedly connected to the inner wall of the protective box, and a rotating shaft is rotatably connected to the inner wall of the positioning plate. A second gear is fixedly connected to the surface of the rotating shaft, and the second gear meshes with one of the first gears.

[0011] Preferably, one end of the rotating shaft is fixedly connected to a fan blade, and the fan blade is positioned corresponding to the filter screen.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. When the protective box is in position for protection, the second gear is driven by one of the first gears, which drives the fan blades to rotate. The fan blades draw in outside air and send it into the protective box, accelerating the airflow and cooling down the multiple first gears inside the protective box, thus extending the service life of the multiple first gears.

[0014] 2. When opening the protective box, push the pull ring to quickly release the limit block from pressing the fixed shaft surface. During the process of rotating to open the protective box, the surface of the cleaning brush comes into contact with the surface of the filter screen, and the cleaning brush automatically cleans the surface of the filter screen to prevent the filter screen from becoming clogged and affecting the ventilation effect after long-term use.

[0023] By setting up a protective box 2, multiple first gears 12 installed on the main body 1 of the laminating machine are shielded and protected. By setting up multiple clearance holes 19, the surface of the conveyor roller 13 is given space clearance. By setting up a cooling and cleaning positioning structure, the multiple first gears 12 inside the protective box 2 are cooled by air. At the same time, the protective box 2 is ensured to protect the multiple first gears 12 stably. The filter screen 5 at the air inlet position is cleaned.

[0024] In this utility model, reference is made to Figure 3 The cooling and cleaning positioning structure includes a fixed cylinder 10 fixedly connected to the surface of the main body 1 of the laminating machine. A limit block 9 is slidably connected to the inner wall of the fixed cylinder 10. A pull ring 20 is fixedly connected to the upper surface of the limit block 9. The surface of the limit block 9 is adapted to the surface of the fixed shaft 8. A tray 7 is fixedly connected to the surface of the main body 1 of the laminating machine. The surface of the fixed shaft 8 is adapted to the surface of the tray 7.

[0025] By setting a limiting block 9, the surface of the fixed shaft 8 is pressed and blocked to maintain the positioning of the protective box 2. By setting a fixed cylinder 10, the sliding of the limiting block 9 is guided and positioned.

[0026] In this utility model, reference is made to Figure 3 A spring 11 is fixedly connected to the inner wall of the fixed cylinder 10, and one end of the spring 11 is fixedly connected to the surface of the limiting block 9.

[0027] By setting spring 11, the surface of the limiting block 9 is driven to press against the surface of the fixed shaft 8.

[0028] In this utility model, reference is made to Figure 2 The inner wall of the protective box 2 is fixedly connected to a filter screen 5, the upper surface of the laminating machine body 1 is fixedly connected to a placement plate 4, the upper surface of the laminating machine body 1 is fixedly connected to a cleaning brush 3, the cleaning brush 3 is used to clean the surface of the filter screen 5, and the surface of the protective box 2 is fixedly connected to a push-pull plate 18.

[0029] By setting up a filter screen 5, dust in the air is filtered out. By setting up a cleaning brush 3, when the protective box 2 is rotated and opened, the surface of the filter screen 5 will come into contact with the surface of the cleaning brush 3, so that the cleaning brush 3 can clean the surface of the filter screen 5.

[0030] In this utility model, reference is made to Figure 4 The inner wall of the protective box 2 is fixedly connected to a positioning plate 16, and the inner wall of the positioning plate 16 is rotatably connected to a rotating shaft 15. The surface of the rotating shaft 15 is fixedly connected to a second gear 14, which meshes with one of the first gears 12.

[0031] By setting the positioning plate 16, the rotation of the rotating shaft 15 is kept stable. By setting the second gear 14, one of the first gears 12 rotates, driving the second gear 14 to rotate.

[0032] In this utility model, reference is made to Figure 4 One end of the rotating shaft 15 is fixedly connected to a fan blade 17, and the fan blade 17 corresponds to the position of the filter screen 5.

[0033] By setting fan blades 17, outside air is delivered into the protective box 2 to cool down the multiple first gears 12 inside the protective box 2.

[0034] Working principle: During use, the first gear 12 is driven to rotate by the drive device on the main body 1 of the laminating machine, which in turn drives the second gear 14 to rotate. The second gear 14 drives the fan blade 17 to rotate through the rotating shaft 15. The fan blade 17 draws in outside air and sends it into the protective box 2, accelerating the airflow and cooling the multiple first gears 12 inside the protective box 2. When it is necessary to open the protective box 2 to lubricate and maintain the multiple first gears 12, pull the pull ring 20 to move the limit block 9 to slide inside the fixed cylinder 10. The compression spring 11 shortens, releasing the limit block 9 from pressing and limiting the surface of the fixed shaft 8. By pushing the push-pull plate 18, the protective box 2 is rotated around the rotating shaft 6 for adjustment. During the rotation of the protective box 2, the cleaning brush 3 cleans the surface of the filter screen 5. At this time, the second gear 14 moves away from one of the meshing first gears 12 through the positioning plate 16, making it convenient to perform maintenance on the multiple first gears 12.
