Material receiving mechanism of cotton feeder and cotton feeder

Abstract

The invention relates to a material receiving mechanism of a cotton feeder. The material receiving mechanism comprises a first feeding roller, a second feeding roller, a beater needle roller and a driving mechanism for driving the first feeding roller, the second feeding roller and the beater needle roller to rotate, wherein two ends of the first feeding roller, two ends of the second feeding roller and two ends of the beater needle roller are arranged on an equipment rack and rotate around their axes, and a receiving area in butt joint and communication with a material inlet of the cotton feeder is formed by the first feeding roller, the second feeding roller and the beater needle roller. The material receiving mechanism further comprises an adjusting mechanism for adjusting the volume ofthe receiving area; the two feeding rollers (the first feeding roller and the second feeding roller) are adopted to cooperate with the beater needle roller to receive materials (cotton fibers or chemical fibers) entering from the material inlet, and when the materials entering the receiving area are excessive and excessive pressure is formed on each feeding roller or beater needle roller, the receiving area is correspondingly increased, so that an excessive extrusion pressure on each roller caused by the materials is avoided. and the phenomenon is avoided that sheet metal of the cotton feederis deformed or damaged.

Description

technical field [0001] The invention relates to a material receiving mechanism of a cotton feeding machine and the cotton feeding machine. Background technique [0002] The air pressure leveling cotton box system is the connecting device between carding and blowing. Its function is to form a uniform mat layer of fibers that have been uniformly opened and mixed and feed them to the carding machine to ensure continuous and uniform supply of the carding machine. Cotton, to achieve continuous blowing and carding process. [0003] Compared with the transmission vibration feeding system, the air pressure leveling cotton box system cotton feeding system has gradually become the mainstream in recent years. The system adopts automatic control technology, and the cotton feeding performance and energy saving are superior to the vibration feeding system; The box system mainly includes a cotton feeding machine and an air cover connected to the material inlet above the cotton feeding mac...

[0003] Compared with the transmission vibration feeding system, the air pressure leveling cotton box system cotton feeding system has gradually become the mainstream in recent years. The system adopts automatic control technology, and the cotton feeding performance and energy saving are superior to the vibration feeding system; The box system mainly includes a cotton feeding machine and an air cover connected to the upper inlet of the cotton feeding machine. Most of the existing pneumatic cotton box feeding machines use single-roller feeding, and some use double-roller feeding to feed cotton. Because the amount of raw cotton or chemical fiber entering from the feeding port is often less, so when there is more raw cotton or chemical fiber entering, a large expansion force will be formed between the roller and the roller or between the roller and the baffle, which will cause the friction between the roller and the roller. The two ends of the drum are connected, and the supporting sheet metal and the deformation of the roller occur in many places around the roller, which makes the equipment frequently replace the sheet metal and the roller, which greatly affects the production efficiency of the enterprise and causes an increase in maintenance costs, and the feeding When there is more cotton, it will affect the uniformity of the cotton or chemical fiber discharged from the needle roller, thus affecting the quality of the machine's discharge surface or chemical fiber
