The present invention relates to a label removal device, and more particularly to a technical structure improvement for a plastic bottle recycling device.

According to the strong promotion of the Environmental Protection Department and the public's gradual recognition of the importance of environmental protection and reducing garbage, in order to recycle used waste plastic bottles, the Environmental Protection Department has set up many plastic bottle recycling stations to carry out plastic bottle recycling work. However, the label film of the plastic bottle is different from the material of the bottle body and needs to be recycled separately. Therefore, the label film must be removed before the plastic bottle can be crushed and collected. Therefore, traditional plastic bottle recycling stations can only collect plastic bottles, and then transport the plastic bottles to the recycling unit for additional label film removal before the plastic bottles can be crushed. The above problem will lead to a reduction in the collection capacity of the recycling station due to the inability to crush the plastic bottles first, which greatly reduces the recycling efficiency, and there are shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and advanced PET bottle recycling device to solve the above problems.
