Uniform preparation device for physical foaming material

Abstract

The invention relates to the technical field of foaming materials, and discloses a uniform preparation device for a physical foaming material. The device comprises a box body, a feeding channel is fixedly installed on the inner wall of the top end of the box body, a discharging channel is formed in the inner wall of the bottom end of the box body in a penetrating mode, a control valve is arranged on the outer side of the discharging channel, a first motor box is fixedly installed at the top end of the box body, a cavity is formed inside the box body, a third motor in a third motor box rotates, when the third motor rotates, a third rotating rod can be driven to rotate through a transmission wheel and a transmission belt, when the third rotating rod rotates, a worm can be driven to rotate, when the worm rotates, a second rotating rod is driven to rotate through a worm gear, when the second rotating rod rotates, a rack plate is driven to move through a gear, so that when the rack plate moves, third partition plates are driven to move through a pushing plate, when every two adjacent third partition plates move mutually, discharging of the physical foaming material can be controlled, and squeezing of the physical foaming material can be controlled.

Description

technical field [0001] The invention relates to the technical field of foaming materials, in particular to a uniform preparation device for physical foaming materials. Background technique [0002] Foam plastic is also called porous plastic. It is made of resin as the main raw material and has countless micropores inside. It is light in weight, heat-insulating, sound-absorbing, shock-proof, and corrosion-resistant. It can be divided into soft and hard. It is widely used for heat insulation and sound insulation. , packaging materials and car and ship shells, foam plastics, microporous plastics, and plastics with numerous micropores in the whole. The physical foaming materials currently on the market are mainly prepared by physical gas foaming and chemical foaming. Physical foaming It is a method of directly using the gas injected into the thermoplastic resin for foaming, and chemical foaming is a method of foaming by using the gas generated by the thermal decomposition of the...

[0003] After retrieval, Chinese Patent No. CN 210410721 U discloses a reaction device for preparing foaming materials, including a reaction kettle body, a stirring rod connected to the output shaft of a rotating motor by transmission, and fixedly installed on the The first layer of stirring impellers, the second layer of stirring impellers and the third layer of stirring impellers on the stirring rod; Diffusion and dissolution in the matrix material, and convection between the stirring impeller and the casing, increases the fluidity inside the reactor body, and solves the phenomenon of uneven heating, but this device has some defects when it is used. There is no vibration screening mechanism, so the density of the obtained material cannot be guaranteed, so the device has certain limitations in use, and there is no stirring and shock absorption mechanism, so it is impossible to cushion the vibration generated when the device is working
