Plastic rod cutting-off device capable of preventing block collapse of cutting surface for plastic processing

Abstract

The invention discloses a plastic rod cutting-off device capable of preventing a cutting surface from collapsing block for plastic processing in the technical field of plastic processing, which comprises a bearing assembly, and the end part of a right cylinder and the end part of a left cylinder are arranged at an interval; arc-shaped convex strips are annularly and equidistantly arranged on the inner wall of a guide-in pipe; the wire cutting assembly is arranged at the interval between the right barrel body and the left barrel body; plastic rods are conveyed in a rolling conveying mode, the plastic rods are evenly preheated through an electric heating ring and a heat conduction ring in the rolling process, surface contact cutting of a traditional cutter is changed into linear contact, resistance during stay wire cutting is reduced, the problem that the end faces of the plastic rods are collapsed during cutting operation is solved, and the service life of the plastic rods is prolonged. Air is guided into the annular grooves formed in the plastic rods in advance through the air guide channels in the air resistance plates, the plastic rod bodies located in the left barrel body and the right barrel body are subjected to relative air resistance, the auxiliary limiting effect is achieved, and the stability during cutting operation is improved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a plastic rod cutting device for preventing the cutting surface from collapsing for plastic processing. Background technique [0002] Plastic processing is also called plastic molding processing. It is a general term for various processes that convert synthetic resin or plastic into plastic products, and is a large production department in the plastics industry. Plastic processing generally includes plastic ingredients, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic has been formed into finished products or semi-finished products, also known as plastic secondary processing. [0003] When plastic rods are processed, they will be cut according to the processing requirements. The existing cutting devices are all realized by punching with cutters. The rod is in surface contact. Due to the brittleness of ...

Problems solved by technology

[0003] When plastic rods are processed, they will be cut according to the processing requirements. The existing cutting devices are realized by punching with cutters. During the processing, the punching force is too large, and the cutter and plastic The rod is in surface contact. Due to the brittleness of the plastic itself, it is easy to cause the problem of collapse of the cut surface of the plastic rod, resulting in pits or uneven cut surfaces on the cut surface, and during the cutting operation, the two sides of the cut surface of the plastic rod lack effective The positioning increases the risk of chipping on the cutting surface and reduces the processing yield. Therefore, we propose a plastic rod cutting device for plastic processing that prevents the chipping of the cutting surface.
