Rolling-cutter and floating-leather roller cotton gin

Abstract

A hob type floating strap roller cotton gin is disclosed in the invention, which is a kind of seed cotton process device separating the seed cotton and cottom fibre. It comprises machine bracket combination, swallowing cotton roller combination, spinal roller combination, hob solder combination, strap roller combination, fixing sword combination, nail tooth roller combination, floating exletree combination, cotton ginning desk, frequency conversion actiyator and so on. Its swallowing cotton roller is drived by the decelerating machine controlled by the frequency conversion actiyator. The strap roller combination fixed on the cotton ginning bracket which is on the left and right wall of the bracket combination is assembled on the cotton ginning desk.

Description

1. Technical field [0001] The invention relates to a cotton processing equipment, which is a cotton gin for separating cotton seeds and cotton fibers in seed cotton, and is especially suitable for processing long-staple seed cotton. 2. Background technology [0002] 1. The traditional roller gin has two feeding parts: mechanical type and electromagnetic speed regulation type: [0003] 1) The mechanical feeding system is driven by a pulse reducer to drive the feed roller. Since the output speed of the pulse reducer is intermittent, the rotation of the feed roller is unstable, resulting in uneven feeding of the cotton gin and affecting the normal operation of the cotton gin. [0004] 2) The electromagnetic speed-adjustable feeding system is driven by a separate slip motor to drive the feeding roller. Since the rotation speed requirement of the cotton gin is very low, when the motor is adjusted to run at a low speed, it is easy to cause low-speed crawling, which also cannot mee...

AI Technical Summary

Problems solved by technology

[0003] 1) The mechanical feeding system is driven by a pulse reducer to drive the feed roller. Since the output speed of the pulse reducer is intermittent, the rotation of the feed roller is unstable, resulting in uneven feeding of the cotton gin and affecting the normal operation of the cotton gin

[0004] 2) The electromagnetic speed-adjustable feeding system is driven by a separate slip motor to drive the feeding roller. Since the rotation speed requirement of the cotton gin is very low, when the motor is adjusted to run at a low speed, it is easy to cause low-speed crawling, which also cannot meet the requirements. Cotton Gin Requirements

[0006] 1) During the processing process, due to the normal wear and tear of the top roller, the diameter becomes smaller, the gap between the hob and the top roller increases, the fixed knife cannot be close to the surface of the top roller, and the pressure between the fixed knife and the top roller decreases, which affects the output of the cotton gin and quality

In order to maintain the pressure between the fixed knife and the top roller and the gap between the hob and the top roller, it is necessary to stop frequently for adjustment, which not only consumes time and effort, but also reduces production efficiency

[0007] 2) Since the fixed knife is made of thin spring steel plate and has a certain degree of elasticity, it is difficult to keep the pressure between it and the top roller even during the adjustment process. This unevenness can easily cause unevenness on the surface of the top roller. Uniform wear, even causing the top roller to be scrapped and unusable, which not only affects the normal use of the cotton gin, but also increases the production cost and causes waste

[0008] 3. In the prior art, Chinese Patent No. 89213737.1 provides a top roller gin, the hob in the working part is 4-8 blades evenly distributed in the direction of the base roller circle, and spiral in the axial direction , the helix angle is 11°-15°. The disadvantage of this technology is that during the rotation of the helically arranged blades, due to the propulsion of the helix, the seed cotton is pushed to one side of the machine, which easily causes uneven processing.
