TECHNICAL FIELD

[0001] The present application relates to the technical field of PVC film waste recycling, in particular to a waste recycling machine for PVC film calendering treatment. BACKGROUND

[0002] PVC film is widely used and has important applications in many fields such as construction, packaging, decoration, electronics, etc. In the PVC film calendering production process, a large amount of waste will inevitably be generated, such as edge material generated when the PVC film before winding is slitting. If these waste materials are not recycled, it will not only cause resource waste, but also increase enterprise cost and environmental pressure;

[0003] The waste recycling machine for PVC film calendering treatment can recycle the waste generated during PVC calendering treatment, thereby avoiding resource waste;

[0005] 1. The existing waste recycling machine for PVC film calendering treatment generally cannot completely crush the waste by one crushing when in use, so the waste after one crushing needs to be manually added to the top of the crushing structure for re-crushing, which increases the labor intensity of the workers and is low in efficiency;

[0006] 2. The existing waste recycling machine for PVC film calendering treatment is not convenient for completely discharging the crushed waste from the recycling machine, because part of the waste after crushing will adhere to the inner bottom surface of the recycling machine, so that the waste cannot be completely discharged from the recycling machine;

[0007] Therefore, a waste recycling machine for PVC film calendering treatment is needed to solve the above problems. SUMMARY

[0015] Preferably, the support rod is in T-shaped structure, which is convenient to support in the inner side of the machine body, and does not affect the installation of the chain and the supporting plate.

[0022] 2. During discharging, the blocking block is only needed to be pulled outwards, so that the discharging port penetrates through the inside and outside of the body. At this time, the reciprocating feeding mechanism can continuously scrape the waste on the bottom surface of the body to the discharging port, so as to more completely discharge the waste.

[0023] 3. The threaded pipe is connected with the lead screw and the screw rod through threads, so that the threaded pipe moves along the lead screw or the screw rod during rotation, and the support plate can be driven to move. The reciprocating movement of the support plate not only facilitates the transportation of the waste on the bottom surface of the body to the upper part of the crushing roller, but also avoids that the relatively wide support plate occupies a large space in the body.
