Description

A kind of nodding device for circular carding machine

technical field

The utility model relates to the field of silk spinning equipment, in particular to a noil picking device for a circular comb machine.

Background technique

The technological process of silk spinning engineering is mainly based on circular carding cotton engineering. Circular carding machine carding is an important process in the process of circular carding cotton. It has a great influence on the carding level of the fine cotton, the quality of the fine cotton, the difficulty of processing in the subsequent process, the quality of spun silk and silk, and the production cost. direct impact. The purpose of circular carding is to make the combed fibers become straight and parallel single fibers through fine combing, remove pupa debris and other impurities remaining in the fine cotton, and remove short fibers and cotton particles at the same time, so that the fine cotton Quality indicators (average fiber length, number of short fibers, number of cotton grains, etc.) meet the requirements of the next step of the process.

In the traditional circular combing process, when the circular comb machine takes out the noil, the carding cylinder of the circular card machine needs to be stopped and meshed with the roller to form the reversal of the carding cylinder, and cooperate with the roller to remove the noil. Therefore, the worker needs to start the carding process of the circular card machine first. Clutch and brake device, at this time the carding cylinder stops, and the workers use cotton hooks to hook up the nodding wound on the carding cylinder. When the noil on the carding cylinder is hooked out, the worker inserts the first noil between the two rollers, and then connects the rollers to the driving source to make the rollers rotate to take out the noil. This operation is extremely cumbersome. According to the analysis, round The motion of picking up the noil in the carding machine can be fitted as a reciprocating linear motion. During the linear motion, it needs to pass between two rollers, but the mechanical structure can not achieve linear reciprocating motion as dexterously as manual operation, so it is necessary Renovate the support of the carding cylinder so that when the cotton swab passes between the two rollers, a space can be reserved between the rollers for the cotton swab to pass through. When the cotton swab moves back, the two rollers will mesh again to pick up the waste Provide power.
