Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-6 A digital printing machine side baffle and bellows baffle synchronous adjustment structure comprises a side baffle adjustment structure, a bellows baffle adjustment structure and a transmission structure.

[0027] The side baffle adjustment structure includes a support box 1, a transmission shaft 2, a transmission tube 3 and a baffle 11. The support box 1 is rotatably connected to a plurality of transmission shafts 2. The transmission shaft 2 is provided with two threaded areas that rotate in opposite directions. Both threaded areas of the transmission shaft 2 are transmission-connected to the transmission tube 3. The transmission tube 3 is connected to the corresponding baffle 11.

[0028] The bellows baffle adjustment structure includes a transmission shaft 14, a transmission tube 15, a baffle 16 and a bellows 21. The bellows 21 is rotatably connected to a plurality of transmission shafts 14. The transmission shaft 14 is provided with two threaded areas with different rotation directions. The two different threaded areas on the transmission shaft 14 are both transmission-connected to the corresponding transmission tube 15. The transmission tube 15 is connected to the corresponding baffle 16.

[0029] The transmission structure includes a rotary drive component, a transmission wheel 15, a transmission wheel 26 and a transmission belt A23. A plurality of transmission wheels 15 are connected to the transmission shaft 2 14, and a plurality of transmission wheels 26 are connected to the transmission shaft 2. The transmission wheel 15 on the transmission shaft 2 14 and the transmission wheel 26 on the transmission shaft 2 are connected through a plurality of transmission belts A23. The rotary drive component can drive the transmission shaft 12 or the transmission shaft 2 14 to rotate. The transmission shaft 2 14 is a ball screw or a screw rod. The transmission tube 2 15 is a ball screw nut or a threaded tube matched with the transmission shaft 2 14. The lead of the threads on the transmission shaft 2 and the transmission shaft 2 14 is the same. The transmission wheel 15 and the transmission wheel 26 are one of a pulley, a synchronous pulley and a sprocket. The transmission belt A23 is one of a belt, a synchronous belt and a chain. The transmission shaft 12 or the transmission shaft 2 14 is driven to rotate by the rotary drive component. The driving wheel 15, the transmission wheel 26 and the transmission belt A23 cooperate with each other, thereby driving the transmission shaft 12 and the transmission shaft 2 14 to rotate simultaneously. The two threaded areas with different rotation directions on the transmission shaft 2 cooperate with the transmission tube 13 respectively, thereby driving the two baffles 11 to approach or move away from each other. The two threaded areas with different rotation directions on the transmission shaft 2 14 cooperate with the transmission tube 2 15 respectively, thereby driving the baffles 2 16 to approach or move away from each other. The spacing between the two baffles 11 and the spacing between the two baffles 2 16 can be adjusted at the same time to adapt to the transmission of different printed materials. Through this synchronous transmission structure, it is convenient to make simultaneous adjustments in two different areas, which is convenient for users to operate and is conducive to making reasonable and effective adjustments to the places where printed material transmission is restricted, thereby improving the relatively accurate effect of the spacing difference between the two baffles 11 and the spacing difference between the two baffles 2 16 after adjustment.

[0030] Reference Figure 2The rotary drive assembly includes a rotating wheel 1 7, a rotating drive unit 8, a rotating wheel 2 9 and a transmission belt B10. A plurality of rotating wheels 1 7 are connected to the transmission wheel 2 6. The rotating drive unit 8 is connected to the support box 1. The output shaft of the rotating drive unit 8 is connected to the rotating wheel 2 9. The rotating wheel 1 7 and the rotating wheel 2 9 are connected by a transmission belt B10. The rotating wheel 1 7 and the rotating wheel 2 9 are one of a pulley, a synchronous pulley and a sprocket. The transmission belt B10 is one of a belt, a synchronous belt and a chain. The rotating drive unit 8 is a motor, preferably a motor with a reducer. The rotating drive unit 8 drives the rotating wheel 2 9 to rotate, and the transmission belt B10, the rotating wheel 1 7 and the rotating wheel 2 9 cooperate to effectively drive the transmission wheel 2 6 to rotate. Through this transmission mode, it is convenient for the rotating drive unit 8 to drive the transmission wheel 2 6 to rotate, and the situation in which the vibration of the rotating drive unit 8 affects the transmission effect of the transmission shaft 1 2 is reduced.

[0031] Reference Figure 1 The side baffle adjustment structure also includes a shaft sleeve 4 and a limiting shaft 22. A plurality of shaft sleeves 4 are connected to the baffle 11. The shaft sleeve 4 is sleeved on the limiting shaft 22. The shaft sleeve 4 slides on the limiting shaft 22, thereby effectively limiting the moving position of the baffle 11, which is beneficial to guiding the moving position of the baffle 11.

[0032] Reference Figure 2 and 3 The bellows baffle adjustment structure also includes a convex plate 17, a roller 18 and a wear-resistant plate 24. A plurality of convex plates 17 are connected to the baffle 16, and a plurality of rollers 18 are rotatably connected to the convex plate 17. A plurality of wear-resistant plates 24 are connected to the bellows 21. The wear-resistant plates 24 are in contact with the circumferential side walls of the rollers 18. The wear-resistant plates 24 are one of copper plates, steel plates and wear-resistant steel plates. Through the cooperation between the rollers 18, the convex plates 17 and the baffle 16, the position of the baffle 16 is effectively restricted, and the displacement of the position of the baffle 16 is further reduced. The setting of the wear-resistant plates 24 allows the rollers 18 to roll on the wear-resistant plates 24, thereby reducing the wear of the bellows 21.

[0033] Reference Figure 1 The bellows baffle adjustment structure also includes a limiting shaft 2 12, a sleeve 2 13, a fixing plate 19 and a limiting shaft 3 20. The bellows 21 is connected with a plurality of limiting shafts 2 12, the baffle 2 16 is connected with a plurality of sleeves 2 13, the bellows 21 is connected with a plurality of fixing plates 19, and a plurality of limiting shafts 3 20 are connected between the fixing plates 19. The limiting shaft 2 12 and the limiting shaft 3 20 pass through the corresponding sleeves 2 13. The limiting shaft 3 20 and the limiting shaft 2 12 are arranged in parallel. The limiting shaft 3 20 and the limiting shaft 2 12 are located at two opposite ends of the bellows 21. Through the cooperation between the limiting shaft 2 12 and the sleeve 2 13, the moving position of the baffle 2 16 is effectively guided to reduce the position deviation of the baffle 2 16. The limiting shaft 3 20 and the limiting shaft 2 12 respectively limit the two sides of the baffle 2 16 to improve the guiding effect of the moving position of the baffle 2 16.

[0034] When in use, the whole is installed on the digital printing machine, the support box 1 is installed at the place where the printed material is transmitted, and the bellows 21 is installed at the place where the bellows of the printing machine needs to be installed. When it is necessary to adjust the distance between the two baffles 11 and the distance between the two baffles 16, start the rotating drive unit 8, and the rotating drive unit 8 drives the rotating wheel 2 9, the rotating wheel 1 7 and the transmission wheel 2 6 to rotate, and simultaneously drives the transmission shaft 1 2, the transmission shaft 2 14, the transmission wheel 1 5 and the transmission wheel 2 6 to rotate through the transmission belt A23, and at the same time adjusts the distance between the baffles 16 and the distance between the baffles 11.
