2results about How to "Consistent output speed" patented technology

The utility model relates to label processing technical field, concretely is a kind of label high-speed die cutting machine.It includes frame, take up roll assembly, transmission assembly and lifting roller assembly, and die cutting bottom plate and multiple hydraulic cylinders are provided on frame;Take up roll assembly is set on frame;Transmission assembly is set on frame;Lifting roller assembly includes the motor b being set on frame, the worm being set on the output end of motor b, four fixed frame being oppositely set on frame, and one lifting block being set on four fixed frame respectively;Four lifting rods are connected with four lifting blocks one by one, and two pairs of lifting blocks are coaxially provided with secondary synchronous pulley a and lower press roller, and transmission assembly is drivenly connected with two secondary synchronous pulley a.The utility model drives worm gear drive by motor, drives mounting bracket and multiple lifting blocks synchronous lifting, so that lower press roller is adjusted according to label thickness, and simultaneously transmission assembly lets two lower press rollers synchronous drive label tape movement.

The utility model discloses a mouth mold for a co-rotating twin-screw extruder, which comprises a mold plate body, and the mold plate body is provided with a feeding end and a discharging end which are oppositely arranged; the runner is arranged at the feeding end of the template body, a plurality of shunt holes which are distributed in parallel are formed in the middle of the runner, and the shunt holes are of a cylindrical conical chamfer transition structure and penetrate through the feeding end and the discharging end of the template body; and the sealing part is arranged at the feeding end of the template and is distributed along the peripheral side of the runner. The distribution holes are arranged in a cylindrical conical chamfer transition structure and are the same in size, shape and direction, the purpose of consistent discharging speed can be achieved after the discharging amount meets the requirement, the discharging speed is kept basically consistent with the bracing speed, plastic expansion generated by high temperature and high pressure is effectively released through extrusion from inside to outside, and molten raw materials are extruded out. And residue accumulation at the discharge port is avoided. And meanwhile, the sealing part is arranged on the runner, so that the runner is tightly attached to the extruder.
