Processing unit for resin sheet or packed food

Abstract

Provided is an apparatus for treating a resin sheet or packaged food etc., which can effectively prevent a rotary shaft from being tangled with the resin sheet etc., and make treatment work be continued for a long time in a stable state. The apparatus has a treatment vessel 31 which houses the resin sheet or the packaged food etc., and has a bulkhead plate 32b with a through-hole 32e formed, the rotary shaft 72 which is inserted into the through-hole 32e and rotated / driven by a driving device 21 arranged outside the treatment vessel 31, and rotary blades 81, ... 84, etc., for agitating the resin sheet etc., with their base ends fixed to the rotary shaft 72, and at least their intermediate parts positioned in the treatment vessel 31. A tangling prevention member 130 having a cylinder part 130a which is forcibly inserted into the through-hole 32e in the inside direction of the treatment vessel 31 from the outside of the bulkhead plate 32b is fixed to the outside surface of the bulkhead plate 32b, and the rotary shaft 72 is inserted into the cylinder part 130a.

Description

technical field [0001] The present invention relates to a processing device for resin sheets or packaged foods, etc., which is used for cleaning and processing resin sheets used as wall materials of simple greenhouses or agricultural materials contaminated by foreign matter on soil surfaces such as covered cultivated land, or Resin sheets such as garbage bags contaminated with beverages, etc.; or when packaging food, etc., which are packaged objects such as food and medicine, etc. use. Background technique [0002] The applicant of the present invention has proposed a kind of separate processing device (hereinafter referred to as processing device), which will be packaged by using resin packaging materials such as food or medicine, respectively, into the resin packaging material and the packaged objects (refer to Patent Document 1). The processing device is suitable for processing packaged food and the like into resin packaging materials and packaged objects respectively. ...

AI Technical Summary

Problems solved by technology

[0005] However, in the above-mentioned conventional processing apparatus, in the process of repeating the above-mentioned processing, the above-mentioned resin packaging material and resin sheet, etc. are entangled on the peripheral surface of the rotating shaft 205 exposed in the above-mentioned processing tank 201, and the entanglement The resin sheet passes through the gap formed between the inner peripheral surface of the above-mentioned partition wall plate 201a and the outer peripheral surface of the rotating shaft 205, and gradually reaches the space 209 formed between the above-mentioned partition wall plate 201a and the above-mentioned support plate 203, so that it is located in the space 209. Around the rotating shaft 205 of the rotating shaft 205, due to the frictional resistance heat generated by the rotational driving of the rotating shaft 205, a molten resin mass is often formed

Particularly, when the length of the resin sheet is longer than the length of the above-mentioned processing tank that constitutes the above-mentioned processing device, not only will it be entangled with the above-mentioned rotating shaft 205 to make the driving device bear a high load, but once the processing device 200 stops, it will continue to rotate. The molten resin around the shaft 205 will harden, and when the processing device 200 is driven again, the rotation shaft 205 will not be able to rotate.

When this kind of problem occurs, it is necessary to remove the hardened resin in the space 209 formed between the above-mentioned partition wall plate 201a and the above-mentioned support plate 203, which is very difficult and requires a very long repair time.
