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 process is mainly manual operation. When the circular comb machine is running, a worker needs to stand on the working platform to take out and put in the sliver without stopping. Regardless of the labor cost of the enterprise or the physical condition of the workers, this solution is not an optimal choice.

Therefore, although the quality of the existing circular carding cotton is good, its automation integration is low, so the cotton production line needs to be automated, and the design of the circular carding machine mechanism to realize the automatic insertion and removal of cotton sliver is to realize the automation of the entire production line prerequisites and foundations.

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 it is particularly important to realize the automatic insertion and removal of the auxiliary splint into and out of the circular carding machine. To achieve this, it is necessary to design a device that can be taken out of the cylinder of the circular comb machine and automatically put into the sub-splint. The cylinder frame of the circular comb machine is one of the main equipment used to fix the sub-splint. In order to facilitate the fixing and release of the sub-splint, it is necessary to The cylinder frame of the circular comb machine is designed with a corresponding fixed release device.

On the stage clip 7, the slide block is on the stage clip, setting the stage clip can guarantee a certain pre-pressure.

In the cotton making process of the present invention, one end of the cotton sliver is clamped by the auxiliary splint, transported to the vicinity of the circular comb machine by the conveyor belt, and put into the counterclockwise circular comb machine through the clockwise rotating splint mechanism. The cotton slivers installed on the auxiliary splint on the cylinder of the circular carding machine are combed by the front and back sides of the front carding cylinder and the rear carding cylinder, and then taken out by the splint taking device, and the cotton on the original auxiliary splint is clamped by the auxiliary splint above the conveyor belt. The slivers and cotton slivers are combed on both sides by the circular carding machine and the front and rear carding rollers. Finally, the combed fine cotton is taken away by the fine cotton taking device, and then the empty secondary splint is taken away by the splint taking device.

The splint fixing release mechanism works as follows:

Firstly, the auxiliary splint is put into the groove of the circular comb machine cylinder by external force, the bottom surface of the auxiliary splint presses the slider, and the two move downward together. At this time, the cam rod slides along the groove on the surface of the slider until it reaches the maximum bottom surface. At the same time, the left and right paws connected to the slider move down along the grooves and move closer together, just entering the two grooves on both sides of the auxiliary splint, and blocking the auxiliary splint.

Then the external force is released. At this time, due to the action of the compression spring, the auxiliary splint moves upward together with the slider, and the cam rod crosses the highest point of the groove on the surface of the slider, and moves downward from the right until the cam rod slides to the intermittent point where it falls back. . Now slide block is locked, and two claws that link to each other with slide block are still in closed state, so the auxiliary splint of this moment is in locked state. After the cotton on the auxiliary splint is combed, it is necessary to take out the auxiliary splint and the cotton as a whole.

Then under the action of external force, the auxiliary splint is pressed down again together with the slide block, and the cam lever slides along the chute to the highest point on the right side.

Finally, the external pressure is released, and the slide block and the auxiliary splint are ejected under the action of the stage clip, and the claws connected with the slide block move upwards along the trajectory until they open, at which point the auxiliary splint can be taken away.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any other form, and any modification or equivalent change made according to the technical essence of the present invention still belongs to the scope of protection required by the present invention .
