Description

Technical Field

[0001] This utility model belongs to the field of vacuum roller hole expansion technology, specifically relating to a vacuum roller hole blockage repair device. Background Technology

[0002] In the paper production process, the vacuum couch roll is a key piece of equipment, mainly used to adsorb and stabilize the paper during paper forming and transport. Its working principle is to use vacuum adsorption force to tightly adhere the paper to the couch roll surface, preventing the paper from shifting, wrinkling, or breaking during high-speed transport, thereby ensuring the continuity and quality of paper production.

[0003] The roller surface is designed with evenly distributed micropores, and the vacuum chamber is located inside the roller. The system generates negative pressure, drawing air out from the pores on the roller surface, creating an adsorption force. However, during adsorption and conveying, dust and other factors often clog the pores, affecting the adsorption effect of the vacuum roller.

[0004] Existing vacuum roller hole clogging repair devices require moving the device to another hole after enlarging one hole before the clogging hole can be enlarged and repaired. This not only consumes a lot of repair time, but may also lead to positioning errors due to frequent manual operation. Utility Model Content
