A longitudinal cutting mechanism of a trademark machine

ActiveCN224411021UFully automatic generationGreat production efficiencyRolling paperMachine
The utility model relates to the technical field of trademark pasting making discloses a longitudinal cutting mechanism of trademark machine, including setting up on the support plate of frame, two the side of facing of support plate all is provided with damping bearing, the damping bearing interval is provided with longitudinal cutting shaft, the longitudinal cutting shaft all uniformly distributed has a plurality of fixed clamps, the side of fixed clamp is provided with adjusting part. The utility model discloses the trademark machine stripping waste mechanism of setting can separate the plastic film roll paper after the film coating with waste film quickly, through the slitting force generated by stripping waste piece, make when separating can reduce the tensile force, thereby avoid the plastic film roll paper when separating and drag too big, cause the plastic film roll paper damage and scrap.

A vortex fan type moisture-proof and dust-proof carrier roller for underground belt conveyors

ActiveCN116331761Bavoid enteringachieve flowRollersThermodynamicsWater vapor
The application relates to a vortex fan moisture-proof and dust-proof carrier roller for an underground belt conveyor, a labyrinth seal assembly, a bearing seat, a carrier roller shaft and a vortex fan forming an air extraction space. End portions of the carrier roller shaft are provided with an axial air passage connected with a dry and clean air source and a plurality of radial air passages communicated with the axial air passage. The radial air passages are communicated with the air extraction space. The vortex fan is rotated by the roller body to realize the flow of dry and clean gas, so that a dry and clean gas environment is always maintained in the air extraction space, water vapor and coal powder in a coal mine underground are isolated from entering the labyrinth seal assembly, the sealing effect of the carrier roller is improved, the moisture-proof and dust-proof capacity of the carrier roller is improved, water vapor and coal powder cannot enter bearings along gaps in the labyrinth seal assembly to cause damage of the carrier roller bearing and the carrier roller, water vapor and coal powder cannot be gathered in the gaps to cause large rotating resistance of the carrier roller and easy jamming, and the stability of the carrier roller and the underground belt conveyor is ensured.
