Auxiliary clamping plate fixing and releasing device for circular comber cylinder frameworks

Abstract

The invention provides an auxiliary clamping plate fixing and releasing device for circular comber cylinder frameworks. The circular comber cylinder frameworks are fixed in a middle support of a rack through a rotating shaft, a ring of circular comber cylinder framework grooves are formed in the inner wall of each circular comber cylinder framework, and a clamping and releasing device is arranged in each circular comber cylinder framework groove; a clamping plate releasing drum and a clamping plate taking drum are arranged over and above the circular comber cylinder frameworks respectively, the two sides of the clamping plate releasing drum and the two sides of the clamping plate taking drum are each provided with a crossed geneva wheel, and in the motion process, the two ends of each cotton clamping plate are clamped in clamping grooves formed in the corresponding crossed geneva wheels; the outer sides of the crossed geneva wheels of the clamping plate releasing drum and the clamping plate taking drum are provided with corresponding cams respectively, a drive gear is arranged on the outer side of the rotating shaft of the circular comber cylinder frameworks, a driven gear is arranged on the outer side of the clamping plate releasing drum, a transmission chain is installed outside transmission teeth of the drive gear and the driven gear in a sleeving mode, and the gear pair is driven by a geneva mechanism to do intermittent motion. According to the device, by improving cam paths of an original design structure, the overall structure is more reasonable, and the precision is higher.

Description

technical field [0001] The invention 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 [0002] 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 fibe...

Problems solved by technology

[0005] In order to improve efficiency, it is necessary to automate the entire process. Because the sliver is soft, it is difficult to operate the sliver alone, so the sub-splint is used as a carrier to move with the sliver in the production line, so the sub-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 circular comb machines. Specific results such as figure 1 As shown, the transmission of the auxiliary splint can be realized through the auxiliary splint transmission device, but in the actual use of the Zhongyuan transmission device, there are still relatively unreasonable things. For example, when the splint falls, it needs to fall vertically, and the original design has no effective distance. The original cam guide rail did not consider the actual production needs, it needs to be optimized, and the relevant accuracy in the actual movement is not enough, so the original device needs to be modified accordingly
