Description

Technical Field

[0001] The invention relates to the technical field of wood plastic floor production, in particular to a dust-free cutting device for wood plastic floor production. Background Art

[0002] In the production process of wood plastic flooring, a large amount of dust generated by traditional cutting devices permeates the air. The dust contains tiny particles of wood plastic materials and components such as chemical additives that may be added. When inhaled by workers, it will cause serious damage to the respiratory system and cause occupational diseases such as pneumoconiosis. Working in a high-concentration dust environment for a long time will put workers' health at great risk. Therefore, dust-free cutting devices are needed for the production of wood plastic flooring.

[0003] The existing dust-free cutting device for producing wood plastic flooring transmits the wood plastic flooring to the bottom of the circular saw blade through the feeding assembly, and drives the circular saw blade to rotate through the motor to cut the wood plastic flooring. The outer end of the circular saw blade is rotatably connected to the shell. However, during the cutting process of the wood plastic flooring, the dust and flying chips generated are adsorbed by the fixed baffle and the dust collector, and the dust and flying chips generated during the cutting process cannot be effectively captured. It is difficult to adapt to wood plastic floors of different sizes, and the dust and flying chips cannot be enclosed, so that some dust is diffused in the working environment, causing serious harm to the health of the operators. After cutting, the wood plastic flooring will have burrs on the cutting surface and sides. The existing method is to cut first and then remove the burrs. The steps are performed separately, which is time-consuming and labor-intensive. Cutting and deburring cannot be performed simultaneously on the same piece of wood plastic flooring, and the efficiency is low.
