The purpose of opening the driving roller is achieved. When the operation is finished and the production is recovered, the side control mechanism is also used for resetting the manual lever, and meanwhile, the pull rod 4 is driven to push the sliding plate 2 inwards until the sliding plate 2 is reset. At the same time, the drive rollers on the two sliding plates 2 are moved inward, respectively, until reset. The purpose that the driving roller clamps the glass is achieved.
When each station is required to drive the short rods to be opened at the same time for some reason, as long as the air circuit switch on the control cabinet is opened, the air cylinder in the side control mechanism starts to act and drives the pull rod 4 to pull the sliding plates 2 outwards at the same time, so that the driving rollers on the two sliding plates 2 move outwards respectively, and the purpose of opening the driving rollers is achieved. When production needs to be recovered, as long as the air path switch on the control cabinet is closed, the air cylinder in the side control mechanism starts to reset, and meanwhile, the pull rod 4 is driven to push the sliding plates 2 inwards, so that the driving rollers on the two sliding plates 2 respectively move inwards, and the purpose of clamping the glass by the driving rollers is achieved.
When the driving short roller is replaced, the pull rod 4 is separated from the side opening and closing mechanism, the linear guide rail clamp is loosened, and the large bottom plate 1 is manually pulled outwards to the limit position of the linear guide rail. The replacement operation can be performed. When the replacement operation is finished and the production is recovered, the large bottom plate 1 is manually pushed inwards to work, so that the linear guide rail clamp is in a locking state, and then the connection between the pull rod 4 and the side opening and closing mechanism is recovered. The horizontal sliding table is restored to the initial working state.
