Description

Technical Field

[0001] This utility model belongs to the technical field of high-speed coating machine equipment, specifically relating to a double-sided dust removal device for high-speed coating machines. Background Technology

[0002] In precision coating processes, the cleanliness of the coating film surface directly affects the coating quality and product performance. During the operation of high-speed coating machines, the coating film easily adsorbs impurities such as dust and particles. Therefore, efficient dust removal is necessary before coating to avoid affecting the quality of the coated product.

[0003] Currently, most high-speed coating machines use pneumatic pressing of paper rollers and pressure rollers for double-sided dust removal. However, the wrap angle cannot be adjusted, the paper roller precision is poor, and there is significant runout. As production efficiency requirements increase, coating machine operating speeds are constantly rising. Under high-speed operating conditions, traditional devices exhibit the following problems: Traditional dust removal devices have poor sticking roller flexibility. When running at high speed, they are prone to hard friction with the film, causing scratches or wrinkles on the film. This is especially true for products with thinner materials and lower tension, which significantly increases the scrap rate. Moreover, when running at high speed, the sticking roller is prone to vibration due to insufficient structural rigidity or poor balance, which affects the dust removal effect and the stability of the film tension, thus affecting the accuracy of subsequent coating processes.

[0004] The adhesive rollers need to be cleaned or replaced regularly, and the traditional structure is difficult to disassemble, which affects production efficiency.

[0005] These problems have become important factors restricting the production quality and efficiency of high-speed coating machines, and there is an urgent need for a double-sided dust removal device that can solve the above defects. Utility Model Content

[0027] The connecting shaft 14 is made of 45 material and is chrome-plated after machining. Its purpose is to connect the input shaft of the reducer 10.

[0028] When the handwheel 13 is turned, the power is reduced and increased in torque by the reducer 10, which drives the support shaft M9 to rotate slowly, thereby driving the swing arm 3 to swing slowly and smoothly around the axis of the support shaft G1 and the support shaft M9, thereby adjusting the relative angle and wrap angle between the dust roller 6 and the material film.

[0029] After adjustment, lock the connecting shaft 14 by tightening the handle 12 to fix the position of the swing arm 3 and the dust roller 6.

[0030] It adopts a swing arm structure, and the angle of the sticky roller can be precisely and smoothly adjusted by handwheel and reducer to make it make proper contact with the film.

[0034] With removable pressure covers designed on the inner and outer sides of the swing arm 3, the sticky roller can be quickly removed for cleaning or replacement without disassembling the entire device, making operation simple and improving maintenance efficiency.

[0035] Example 4 Based on Example 3, the two pairs of swing arms 3 located on the operating surface and the transmission surface are welded together by a support 8. The support 8 is made of seamless steel pipe, welded and painted, in order to connect the operating surface and the transmission surface of the swing arms 3 to form a stable frame structure, enhance the overall structural rigidity, and improve the overall structural strength.

[0036] Brackets are installed between the swing arms to enhance the overall structural rigidity, ensure the stability of the film tension, and reduce the scrap rate. Self-aligning bearings are used to support the dust-adhesive roller, improving rotational flexibility and operational smoothness, and effectively reducing vibration during high-speed operation.

[0037] Example 5 Based on embodiment 4, the support 11 is made of Q235-A material and is painted after processing. One end is fixed to the wall panel 16, and the other end is provided with a through hole. The connecting shaft 14 passes through the through hole to support the connecting shaft 14.

[0038] Example 6 Based on embodiment 5, the locking handle 12 is fixed on the support 11. The purpose is to tighten the locking handle 12 after adjustment, press the connecting shaft 14 to lock the current position, and achieve locking and fixing of the swing arm 3 position.

[0039] After adjustment, lock the connecting shaft using the tightening handle to fix the position of the sticky roller. The swing arm has a notch and a removable pressure cap for easy installation and removal of the sticky roller.

[0040] Example 7 The present invention relates to a double-sided dust removal device for a high-speed coating machine, the structure of which is as follows: Figure 1 and Figure 2 As shown, the device includes a wall panel 16 as the mounting base and support shafts G1 and M9 respectively mounted on the wall panel 16. A swing arm 3 is fixedly connected to the support shaft G1 and support shaft M9 respectively. A dust roller 6 is mounted between the ends of the opposing swing arms 3 through a self-aligning bearing 5. A reducer 10 is mounted on the outside of the wall panel 16. One end of the support shaft M9 passes through the wall panel 16 and is connected to the output shaft of the reducer 10. The input shaft of the reducer 10 is connected to a connecting shaft 14. A handwheel 13 is connected to the connecting shaft 14. A locking handle 12 for locking the position is mounted on the connecting shaft 14.

[0041] A support 8 is provided between the opposing swing arms 3. The purpose is to connect the operating surface and the transmission surface of the swing arms 3 to form a stable frame structure, enhance the overall structural rigidity, and improve the overall structural strength.
