Description

Technical Field

[0001] The utility model relates to the technical field of plate-making rollers, in particular to a plate-making roller capable of preventing slipping. Background Art

[0002] The platemaking cylinder is a key component used in the platemaking process. In the printing industry, the platemaking cylinder is usually a cylindrical device. Its main function is to carry the printing plate or other materials related to platemaking, and work with other components in the platemaking process to achieve the transfer of graphic information from the original file to the printing plate.

[0003] When oil or dust accumulates on the surface of the plate-making cylinder, the oil will make the surface smooth, reduce the friction coefficient, and cause slippage during transmission or operation. If impurities such as dust accumulate on the surface, they may fill some microscopic rough structures, reduce the surface roughness and thus affect the friction. For example, in some industrial production scenarios, if the surface of the plate-making cylinder has accumulated oil and dust due to long-term cleaning, problems such as reduced printing quality, unstable equipment operation, and even malfunction and shutdown may occur. Regular professional cleaning and maintenance of the cylinder to remove these friction-reducing substances is an important measure to ensure its normal, efficient, and stable operation. Timely cleaning can effectively maintain the anti-slip performance of the cylinder. However, this cleaning and maintenance basically relies on manual cleaning by humans in conjunction with cleaning components. Since the plate-making cylinder is cylindrical, it is necessary to operate around its surface during cleaning. There may be some areas that are inconvenient to reach, resulting in incomplete cleaning, and manual cleaning is relatively slow, especially for situations where frequent cleaning is required, which will consume more time and manpower.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A plate-making roller for preventing slipping comprises a frame 1, a roller body 2 and a wiping ring 12. The wiping ring 12 is sleeved on the outside of the roller body 2 and a wiping cloth is provided on the surface in contact with the roller body 2. A reciprocating screw 3 is installed on the frame 1. A movable frame 5 is threadedly sleeved on the reciprocating screw 3. An upper gear 6 and a lower gear 9 are installed on the movable frame 5. The upper gear 6 cooperates with the frame 1 through a rotating mechanism. The upper gear 6 and the lower gear 9 are connected through a transmission mechanism. The movable frame 5 is connected to the wiping ring 12 through a connecting mechanism. The lower gear 9 is connected to the wiping ring 12 through a rotating mechanism.

[0022] The rotating mechanism includes a rack 7 installed on the frame 1, and the upper gear 6 is meshed with the rack 7. With the help of the upper gear 6 and the rack 7, the upper gear 6 can be rotated when the movable frame 5 moves on the reciprocating screw 3.

[0023] The transmission mechanism includes a driving gear 8 installed on the upper gear 6, and a transmission gear 10 is installed on the lower gear 9. The driving gear 8 is meshed with the transmission gear 10. With the help of the above-mentioned driving gear 8 and the transmission gear 10, the lower gear 9 can be rotated when the upper gear 6 rotates.

[0024] The connecting mechanism includes a connecting frame 11 installed on the movable frame 5, and an annular connecting groove 14 is provided on the wiping ring 12. The vertical cross-sectional views of the connecting frame 11 and the annular connecting groove 14 are both L-shaped. With the help of the above-mentioned connecting frame 11 and the annular connecting groove 14, it is ensured that the wiping ring 12 can rotate under the support of the connecting frame 11 and move outside the drum body 2 without being separated from the connecting frame 11.

[0025] The rotating mechanism includes a gear ring 13 mounted on the wiping ring 12, and the lower gear 9 is meshed with the gear ring 13. By means of the lower gear 9 and the gear ring 13, the wiping ring 12 can rotate in coordination with the gear ring 13 when the lower gear 9 rotates.

[0026] A limit rod 4 is provided on the frame 1, and the limit rod 4 is parallel to the reciprocating screw 3. The limit rod 4 slides through the movable frame 5. With the help of the limit rod 4, the movable frame 5 is limited, thereby preventing the movable frame 5 from rotating with the reciprocating screw 3.

[0027] When the utility model is in use, the drum body 2 is supported by the frame 1 and is placed in a suitable place. The frame 1 is provided with a driving motor connected to the reciprocating screw 3. After the driving motor is started, the reciprocating screw 3 can be driven to rotate. When the reciprocating screw 3 rotates, the movable frame 5 drives the equipment components installed thereon to move back and forth. In this process, the upper gear 6 rotates under the action of the rack 7, and the upper gear 6 cooperates with the active gear 8 and the transmission gear 10 to drive the lower gear 9 to rotate. The lower gear 9 can drive the wiping ring 12 to rotate with the help of the ring gear 13. At this time, the wiping ring 12 is in a state of moving back and forth and rotating, and cooperates with the wiping cloth installed thereon to realize the wiping and cleaning operation of the drum body 2, ensure its cleanliness, keep the surface of the drum body 2 clean, avoid the accumulation of materials that reduce friction such as oil, dust, etc., thereby avoiding its slipping.
