The outer wall of the horizontal cylinder 8 is fixedly sleeved with a pulley 10. A safety valve 11 is installed at one end above the outer wall of the device body 1. The safety valve 11 is a normally closed opening and closing part under the action of external force. When the medium pressure in the equipment or pipeline increases to more than the specified value, it prevents the medium pressure in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system. The special valve can prevent the internal pressure of the device body 1 from being too high, which is convenient for safe use. A transparent cover 12 is arranged on the outside of the safety valve 11. The transparent cover 12 is made of transparent PVC material, which can facilitate external operators to see whether there is internal medium of the device body 1 inside it, so as to facilitate timely operation. Maintenance and repair, the transparent cover 12 is threadedly connected to the device body 1, and the first ring 2 and the second ring 3 are internally provided with a sandwich insulation sheet 13, and the insulation sheet 13 is a ceramic fiberboard with good insulation effect.

The convex balls 16 are tightly pressed against the outer wall of the wire 9, and the outer wall of the pulley 10 is provided with convex and concave edges, which can increase the friction inside the outer wall groove of the pulley 10, so as to facilitate the subsequent stable transmission of the belt.
[0019] During the use of the plastic cup recycling device, the operator first installs the device body 1 inside the screw extruder used for plastic recycling, so that the cross tube 15 is sleeved on the outer wall of the wire 9, and the rotary cylinder 14 is threadedly connected with the cross cylinder 8. Due to the tight relationship between the convex ball 16 and the outer wall of the wire 9, a supporting force can be provided to the wire 9, so that there is a sufficient distance between the wire 9 and the inner wall of the cross cylinder 8 without friction. It is learned that during the installation of the device body 1, the pulley 10 needs to be driven by a belt, passing through the cross cylinder 8, the circular plate 7, the support rod 6 and the first ring 2 The transmission can realize that the pulley 10 drives the device body 1 to rotate together during the rotation.
