Description

A New Type of Fixing and Release Device for the Cylinder Skeleton of Circular Combing Machine

technical field

The utility model relates to the field of silk spinning equipment, in particular to an auxiliary splint fixing and releasing device for a cylinder frame of 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.

The traditional circular comb technology is mainly manual operation. In Hai'an County, Jiangsu Province, which enjoys the "Hometown of Cocoon and Silk in China" and "Hometown of Lake and Mulberry in China", sericulture production has a long history. Before liberation, there was a certain production scale. In 1949, the county produced 364 dan of cocoons; in 1959, it produced 228 dan of cocoons, ranking first in Nantong and becoming one of the 19 key sericulture counties in the province. In 1966, it produced 4,232 dan of cocoons, ranking first among counties in northern Jiangsu. In 1997, it was rated as the "Hometown of Cocoon and Silk in China" by 7 ministries and commissions including the Chinese Sericulture Society.

The silk spinning industry in Hai'an County has developed from one silk spinning factory before to many now, and the production has transitioned from the original traditional circular combing process to the current combination of circular combing process and combing process. Silk spinning mills have developed from conventional silkworm silk specifications 10 years ago to the current product structure combining conventional silkworm silk specifications and special silkworm silk specifications. However, some silk spinning mills still use the traditional circular combing process.

In order to improve efficiency, it is necessary to automate the entire process. Because the cotton sliver is soft, it is difficult to operate the cotton sliver alone, so the auxiliary splint is used as a carrier to move together with the cotton sliver in the production line, so the auxiliary splint is automatically put in and out. The circular comb machine is particularly important. For this reason, the applicant designed the corresponding auxiliary splint transmission device and applied for a related patent. The patent number of this patent is CN 201610378316.3, and the patent name is an automatic pick-and-place auxiliary splint device for a circular comb machine. The specific results are shown in Figure 1. The transmission of the auxiliary splint can be realized through the transmission of the auxiliary splint. However, there are still relatively unreasonable things in the actual use of the Zhongyuan transmission. For example, when the splint falls, it needs to fall vertically. The original There is no effective distance in the design, the original cam guide rail does not consider the actual production needs, and needs to be optimized, and the relevant precision in the actual movement is not enough, so the original device needs to be modified accordingly.

The specific improvements are as follows:

The improvement of the bracket of the utility model is shown in Figure 2. Considering that when the splint falls, it needs to fall vertically. We moved the position on the bracket of the splint cam 2 to the middle to ensure the effective distance of the splint in the process of falling. .

The improvement of the cam track of the utility model is shown in Figure 4:

The improvement of the cam for the plywood device is as follows:

When the splint is put into the cam, the splint is easy to sag or even fall off, so the place where the splint is placed in "A" should be above the horizontal line of the center of the cam; after the splint enters, it will rotate because the ears on both sides are cylindrical. In order to enter the fixed exit of the drum faster, the radius of the cam track at "D" should be increased or the distance from the track to the center of the cam should be decreased. The cleats are still running on the cam track before they fall, and need a cushioned ramp, so the ramp at "C" is set to be flat. Considering that the edge of the roller is still driving the splint when the splint is falling, so an outlet is set at "B".

The cam for taking splint device is improved as follows:

On the basis of the optimization of the splint placing device, the steps for us to deal with the splint removing device are also much simpler. The changes to the rollers are similar to those for the cleat rollers, as are the improvements to the cam track, but with a slightly larger gentle slope.

The utility model cylinder improvement is shown in Figure 3:

Combined with the modified cam track, we shorten the protruding part of the roller, and the "D" part is shorter than the "E" part. The principle is the same as the last modification of the cam, leaving an outlet for the splint.

The above are only preferred embodiments of the utility model, and are not intended to limit the utility model in any other form, and any modifications or equivalent changes made according to the technical essence of the utility model still belong to the utility model. Scope of protection claimed.
