Description

Technical Field

[0001] The utility model belongs to the technical field of floor waste recycling equipment, in particular to a clip-on type waste recycling device for producing plastic floors. Background Art

[0002] In the production process of plastic flooring, there will be a lot of waste that is not enough to be cut into blocks. If these wastes are not effectively recycled and processed, it will not only cause a waste of resources, but also pollute the environment. Therefore, it is particularly important to invent a device to recycle the floor waste. Most of the existing recycling devices directly collect the floor waste. The more advanced recycling devices will be equipped with a crushing device to simply crush the waste. However, this recycling method has a problem that when storing and collecting, there will be a lot of gaps between the irregular waste, which will take up more storage space. In addition, when recycling and reshaping, it needs to be ground again, which increases the recycling process.

[0003] At present, there is an existing PVC floor production device with waste recycling (such as patent number: CN209350320U), which discloses a PVC floor production device with waste recycling, including a support frame, a motor is provided on the front surface of the support frame, and the motor is detachably connected to the support frame. A transmission shaft is provided at the output end of the motor, and the transmission shaft is rotatably connected to the motor. A transmission belt is provided on the outer wall of the transmission shaft, and the transmission belt is rotatably connected to the transmission shaft. A rotating shaft is provided on the end of the transmission belt away from the transmission shaft; the dust absorbed by the fan is sent into the filter box through a duct for filtration, so that the dust generated during cutting will not pollute the air and cause harm to the human body. A motor is provided on the front surface of the support frame, so that the motor drives the transmission belt to rotate, so that when the transmission belt rotates, it can drive the L-shaped plate to move to the right, and then the L-shaped plate can push the cut waste into the waste box for storage, which facilitates the collection of waste.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found:

[0005] 1. The existing device is only provided with a waste box for storing floor waste, but is not provided with a crushing device. When storing waste, there will be a large number of gaps between irregular wastes, which will take up a lot of storage space and cannot store more waste. Therefore, the existing device has the disadvantage of not being able to store more waste.
