Embodiment Construction

[0012] The present invention will be described in further detail below by means of specific embodiments:

[0013] The reference numerals in the accompanying drawings of the description include: the main drive wheel 1, the secondary drive wheel 2, the connecting rod 3, the drive rod 4, and the track 5 of the cutting head.

[0014] The embodiment is basically as attached figure 1 As shown: a stepper motor is fixedly installed on the frame, and the output axis of the stepper motor is perpendicular to the paper surface, so it is not shown in the figure. The output shaft is keyed with a coaxial main drive wheel, and the main The driving wheel rotates in the vertical plane under the drive of the motor, and is connected with the auxiliary driving wheel through bearing rotation on the top of the frame, and the auxiliary driving wheel and the main driving wheel form a friction wheel pair. The main driving wheel is driven to rotate by the motor, and the main driving wheel drives the au...

Abstract

The invention discloses a rigid polyurethane foaming plastics cutting device which can reduce heat energy consumption. The rigid polyurethane foaming plastics cutting device comprises a rack, wherein a cutting head and a rotary motor are installed on the rack. A main drive wheel coaxial with an output shaft of the rotary motor is connected onto the output shaft. An auxiliary drive wheel is rotatably connected onto the rack, and the main drive wheel and the auxiliary drive wheel form a rolling wheel pair. The middle section of a drive rod is eccentrically hinged to the main drive wheel, the end of a connection rod is eccentrically hinged to the auxiliary drive wheel, the other end of the connection rod is hinged to one end of the drive rod, and the cutting head is arranged at the other end of the drive rod. The track of the cutting head on the drive rod roughly does linear reciprocating motion, the cutting head can extend into a notch along the cutting depth in the foaming plastics cutting process, and the requirement for power of a heating device on the cutting head is not high.

Description

technical field [0001] The invention relates to a foam plastic cutting device. Background technique [0002] Polyurethane rigid foam mostly has a closed-cell structure, which has excellent characteristics such as good heat insulation effect, light weight, high specific strength, and convenient construction. It also has the characteristics of sound insulation, shockproof, electrical insulation, heat resistance, cold resistance, and solvent resistance. It is widely used in Insulation materials for refrigerators and freezers, cold storage, refrigerated trucks and other insulation materials, buildings, storage tanks and pipeline insulation materials, a small amount is used in non-insulation occasions, such as imitation wood, packaging materials, etc. Generally speaking, lower density polyurethane rigid foam is mainly used as heat insulation (insulation) material, and higher density polyurethane rigid foam can be used as structural material. [0003] Polyurethane rigid foam is g...
