Fixed-point cutting device for wood-plastic composite board production

Abstract

According to the fixed-point cutting device for wood-plastic composite board production. Protruding blocks are slidably mounted in a transverse frame and a sliding plate correspondingly, the protruding blocks are fixedly mounted at the tops of movable blocks, the movable blocks are slidably mounted in fixed seats, adjusting rods are movably mounted in the movable blocks, and rollers are arranged in the adjusting rods; and the rolling wheel is attached to the surface of a special-shaped wheel, and the special-shaped wheel is fixedly installed at the output end of a second motor. When the concave position of the special-shaped wheel makes contact with the idler wheel, a distance difference is formed, the movable block at the top of the adjusting rod is driven to be pushed rightwards under the pulling force of the spring, meanwhile, the protruding block at the top end of the movable block slides in the fixing base, and the cut-off wood-plastic composite board is pushed into the adjacent hot pressing roller in the sliding process; and the wood-plastic composite board is flattened and taken out of the machining bin at the same time, the whole structure is cut off and discharged integrally, the labor amount is reduced, burrs on the cut-off face are removed through thermal shrinkage, and the cut-off face is smoother.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic composite board production and processing, and in particular relates to a fixed-point cutting device for wood-plastic composite board production. Background technique [0002] Wood-plastic composite board is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesive, and more than 50% of wood powder, rice husk, straw, etc. Waste plant fibers are mixed into new wood materials, which need to be cut when processing wood-plastic composite panels, so as to be used in different fields. [0003] In the process of cutting, the cutting is difficult, and there are burrs on the cutting surface, the tooth size of the cutting surface is not accurate enough, it is impossible to ensure that the cutting size is the same every time, and the cutting effect is poor. In a...

[0003] In the process of cutting, the cutting is difficult, and there are burrs on the cutting surface, the tooth size of the cutting surface is not accurate enough, it is impossible to ensure that the cutting size is the same every time, and the cutting effect is poor. In addition, it cannot be automatically discharged after cutting, and the amount of manual labor is required. Big
