Problems solved by technology

[0008] Among the existing cold cutting equipment, common equipment based on wire saws, band saws or vibrating knives adopts a one-dimensional cutting mode, and each operation can only cut one knife. In order to obtain polyurethane small pieces, it is necessary to repeatedly feed materials three times. This method is difficult to meet emergency conditions. Disposal speed requirements
The cold cutting equipment based on the vibration knife can be made into a two-dimensional cutting mode, such as the double-knife cutting machine of Wintech International Company. After placing the foam block on the conveyor belt for positioning, the operator first cuts with a vertical knife or a horizontal knife, and then Then switch to another cutter for cutting, this mode can not meet the speed requirements of emergency treatment

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as Figure 1 to Figure 4 As shown, the feeding barrel 1 is a cylinder with an inner diameter of 300mm and a wall thickness of 1.5mm.

[0040] The vertical knife group 2 includes two groups of grille garden knives, each set of grille garden knives includes five circular saws with a diameter of 350mm, the thickness of the sawtooth is 3.2mm, the thickness of the disc is 1.8mm, and the distance between the circular saws is 50mm, parallel to each other and fixed on On a rotating shaft with a diameter of 50 mm, bearings are installed at both ends of the rotating shaft, and a shaft coupling is installed at one end of the bearing outside.

[0041]In order to ensure the stability of the vertical knife group 2 when it is working, heat treatment is carried out on the rotating shaft, and the end faces of the fixing ring and the nut are finel...

Abstract

The invention relates to a polyurethane foam plastic slabbing machine. A circular feeding barrel and knife teeth of a circular disc saw are used for enabling polyurethane foam blocks to be kept in a cylindrical shape after vertical cutting and horizontal cutting, the relative positions of foam strips are kept unchanged, the phenomenon that a cutter set is locked caused by large-area contact of the foam strips and the circular disc saw can be avoided, after the foam strips are cut off through a horizontal cutter, the polyurethane foam blocks are formed, and the polyurethane foam blocks are sent to a packaging bag in a blowing mode through air flow. According to the polyurethane foam plastic slabbing machine, slicing, slitting, slabbing and packaging of the foam blocks are achieved during a one-time feeding process, cutting speed is high, and the polyurethane foam plastic slabbing machine is suitable for quick cutting of polyurethane foam plastics.

Description

technical field [0001] The invention relates to a cutting machine for foamed plastics, in particular to a cutting machine for polyurethane foamed plastics. Background technique [0002] Polyurethane is a polymer produced by copolymerization of isocyanate and polyol. Polyurethane products are divided into two categories: foamed products and non-foamed products: foamed products include soft, rigid and semi-rigid polyurethane foam; non-foamed products include coatings, adhesives, synthetic leather, elastomers and Elastic fibers etc. Polyurethane materials have excellent performance, wide range of uses, and various types of products, among which polyurethane foam is the most widely used, accounting for about 70% of the total consumption of polyurethane products. [0003] Polyurethane foam molding processing methods can be divided into two types: the first is a one-time molding method, such as injection molding, compression molding, calendering, etc., using molds to produce foa...
