Defoaming device and using method thereof

Abstract

The invention provides a defoaming device and a using method thereof, and relates to the field of application of defoaming devices. The defoaming device comprises a support and a movable support. A gear motor is arranged at the top of the support, a lateral compression roller is arranged on one side of the gear motor, a gear pump is arranged at the top of the movable support, and a degassing mechanism is arranged between the lateral compression roller and the gear pump. The degassing mechanism comprises a machine barrel, the machine barrel is arranged between the lateral compression roller and the gear pump, and a screw rod is arranged in the machine barrel. According to the defoaming device, bubbles of a rubber material are broken under stirring and shearing of the screw rod, so that gas is removed from the rubber material in the machine barrel, the removed gas is pumped away by a vacuum pump arranged on the outer side of an exhaust port fixedly connected with the top of the machine barrel, and the rubber material is cut and instantly forms low pressure when moving to pass through a groove in the outer side of the screw rod in the machine barrel; and gas in the rubber material is released, and the gas in the rubber material can be completely released under the shearing action of the screw rod and the machine barrel.

Description

technical field [0001] The invention relates to a device, in particular to a defoaming device and a use method thereof, belonging to the technical field of defoaming devices application. Background technique [0002] The device is a rubber machine used to extrude treads, inner tubes, hoses and various rubber profiles, and it is also used to coat cables and wire products, etc. The common screw device is the screw device. When it is working, the rubber material is stirred, mixed, plasticized and compacted in the barrel by the rotation of the extrusion screw, and then moves towards the machine head, and finally extrudes a certain shape from the die. product. [0003] Because there will be water vapor, air, volatile gas, etc. in the rubber, if these gases are not discharged from the inside of the rubber in time, as the screw pushes the rubber further forward, these gases will be retained in the rubber, except for a small amount. Some of the gas on the surface of the rubber may...

AI Technical Summary

Problems solved by technology

This will affect the density of the product, form air bubbles inside the finished product, or form depressions and protrusions on the surface of the finished product, which will affect the product quality and increase the reject rate of the product

Air bubbles cannot be completely eliminated even with a venting device

This problem has always been a difficulty in rubber and plastic extrusion molding
