Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor structural parts, in particular to an automatic roller rubber coating device. Background Art

[0002] Belt conveyor pulleys require lagging during production. In recent years, hot-vulcanized lagging has been phased out due to environmental concerns. Cold-vulcanized lagging is the most commonly used cold-vulcanized lagging method on the market. It involves five steps: surface grinding, surface pretreatment, initial coating of the pulley surface and pretreatment of the rubber sheet, rubber sheet bonding, trimming of excess rubber sheet, and seam repair. The rubber sheet bonding step requires operators to use their bodies to hold the rubber sheet in place to prevent movement. The plastic sheet covering the rubber sheet is then removed. Three people work simultaneously, with each person lifting the ends of the removed rubber sheet. After bonding, compacting rollers are used to press the sheet from the center toward the ends to remove any air trapped beneath it. The sheet is then manually pressed from top to bottom and then from the center toward the ends until it is fully adhered to the pulley. A rubber hammer is then used to hammer the sheets back and forth, ensuring a secure bond. This process takes approximately 40-50 minutes. This process requires the collaboration of multiple people and is a repetitive cycle, which consumes a lot of manpower and operation time and has low efficiency. Utility Model Content
