Extrusion device for cotton stalk skin-core separator

Abstract

The invention belongs to the field of cotton stalk processing equipment, and particularly relates to an extrusion device for a cotton stalk skin-core separator. The device comprises an extrusion shell internally provided with an extrusion chamber; the extrusion chamber is internally provided with two groups of rotating rollers; a pressurizing piece is arranged above the rotating rollers; the top end of the pressurizing piece is fixedly connected with a first spring; the top end of the first spring is fixedly connected with the inner top wall of the extrusion chamber; a variable resistance detection mechanism and an air pressure pressurization mechanism are arranged at the top end of the pressurizing piece; the air pressure pressurization mechanism is connected with a valve assemblyon the outer top wall of the extrusion shell; and the valve assembly is electrically connected with the variable resistance detection mechanism. According to the device, the diameters of different cotton stalks are measured, and when the device faces the cotton stalks with different diameters, the air pressures in the air pressure pressurization mechanism are different, so that when the cotton stalks with different diameters are extruded, enough extrusion force can be provided to ensure that the connection force between cotton stalk cores and cotton stalk skins is greatly reduced.

Description

technical field [0001] The invention belongs to the field of cotton stalk processing equipment, and in particular relates to an extruding device used on a cotton stalk skin-core separator. Background technique [0002] Cotton stalk skin can become textile fiber after degumming. Cotton stalk core is an excellent raw material for pulping and papermaking. Therefore, cotton stalk has great recycling value. For separation, the current machinery usually pressurizes the cotton stalk, then beats the cotton stalk, and then breaks the cotton stalk core and separates it from the cotton stalk skin, and then realizes the separation of the cotton stalk skin and the cotton stalk core by mechanical means. separation between. [0003] However, in the process of actually pressurizing the cotton stalk, the contact force between the cotton stalk core and the cotton stalk skin is still strong, which will cause the subsequent cotton stalk core and cotton stalk skin to be difficult to pressurize....

Problems solved by technology

[0003] However, in the process of actually pressurizing the cotton stalk, the contact force between the cotton stalk core and the cotton stalk skin that applies pressure to the cotton stalk is still strong, which will make it difficult for the subsequent cotton stalk core and cotton stalk skin to compress. Separation, and because different cotton stalks have different thicknesses, this will make the extrusion effect on cotton stalks poor. If it is necessary to ensure that the contact force between the cotton stalk core and the cotton stalk skin is greatly weakened during the extrusion process , then when the diameter of the cotton stalk is larger, the extrusion force on the cotton stalk needs to increase significantly with the increase of the diameter of the cotton stalk, but the current equipment cannot meet this condition, so the current equipment will Less effective for cotton stalk extrusion
