Description

Technical Field

[0001] The utility model relates to the technical field of cotton spinning processing, in particular to an automatically feeding component with a limiting function. Background Technique

[0002] Cotton yarn is a process of spinning cotton fibers into continuous yarns. After plying, the toughness of the yarn can be increased. The yarn is sorted through multiple steps such as cotton blending, bale opening, carding, drawing, and winding. Generally, a carding machine often uses a feeding component to assist the yarn in entering and exiting. Referring to a carding machine feeding device for cotton yarn processing with the application number CN20232190153.8, it includes: a feeding port is arranged at the top of the box body, and two beater wheels are arranged obliquely and rotatably below the feeding port; a dust removal net is arranged obliquely below the two beater wheels, and the lower part of the dust removal net is communicated with a receiving box, and a blanking channel is arranged between the lower end of the dust removal net and the corresponding side wall of the box body; a conveyor belt is arranged horizontally and rotatably below the blanking channel; a flattening component is arranged in the box body above the conveyor belt, including a first gear rotatably arranged in the box body above the conveyor belt driven by a first motor, a connecting frame is vertically arranged in the box body, two racks arranged inside the connecting frame on both sides of the first gear are adapted to the first gear, and a pressing plate is connected to the lower end of the connecting frame through a guide rod. The utility model has the advantages of being able to preliminarily remove impurities from the cotton yarn and being able to flatten the cotton yarn.

[0003] Although this case can comb the yarn and clean dust and dirt at the notch through the beater wheel, it does not set up a sorting mechanism. After the yarn enters the device, there is a lack of an auxiliary positioning mechanism, and the yarn is prone to merging or misalignment during feeding, which is inconvenient for subsequent combing. Moreover, the positions of multiple rollers inside are different, and it consumes quite a lot of electricity to drive.

[0004] Now, a new type of automatically feeding component with a limiting function is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatically feeding component with a limiting function to solve the problem of the lack of a sorting mechanism proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an automatically feeding component with a limiting function, including a housing and a yarn inlet. The yarn inlet is arranged between the front and back at the center of the left side of the housing.

An upper roller shaft is installed above the center of the right side inside the housing, and a lower roller shaft is installed below the center of the right side inside the housing.

[0010] Preferably, the first bevel gear is clamped outside the second bevel gear. The second bevel gears are symmetrically fixed to the front and rear ends of the toothed roller. The output shafts of the servo motors are respectively fixedly connected to the three front longitudinal rods.

[0011] Preferably, a chute is provided at the lower right corner of the housing, and a clamping plate is movably inserted into the chute. A slider is fixed to the right side of the clamping plate, and a flat groove is horizontally provided at the center between the slider and the clamping plate.

The front end of the lead screw 19 is fixedly connected to a rotating handle 20. A driving motor 15 is installed at the center of the left side at the back of the housing 1. Six groups of toothed rollers 4 are movably connected between the front and back on the inner side of the housing 1;

[0023] The rotating handle 20 can rotate movably in the front left of the housing 1. The rotating handle 20 can control the lead screw 19 to rotate in place inside the rotating cylinder 3. The moving rod 16 can slide between adjacent fixed rods 17. The moving rods 16 are symmetrically fixed to both the top and bottom of the engaging sleeve 18;

[0024] Specifically, as Figure 1 and Figure 2 shown, according to the number of wire harnesses to be transmitted, they are respectively guided between adjacent moving rods 16 and fixed rods 17. According to the tightness of the source yarn, rotate the rotating handle 20 exposed at the front end. By this, rotate the lead screw 19 inside the rotating cylinder 3, and multiple engaging sleeves 18 can be translated synchronously along the inner chamber, and then guide the moving rods 16 to move simultaneously between adjacent fixed rods 17 to prevent the yarn from closing up again.

[0025] Embodiment 2: Three servo motors 6 are installed above the surface of the housing 1. Three longitudinal rods 5 are movably connected to both the front end and the back end inside the housing 1. Two first bevel gears 7 are fixed to the outside of the longitudinal rods 5. Second bevel gears 8 are fixed to both the front end and the back end of the toothed roller 4. An upper roller shaft 9 is installed above the center on the right side inside the housing 1. A lower roller shaft 12 is installed below the center on the right side inside the housing 1;

[0027] Specifically, as Figure 1 and Figure 3 shown, use the three servo motors 6 to control the first bevel gears 7 installed at the front end of the toothed roller 4 to mesh with the second bevel gears 8, thereby rotating the longitudinally adjacent toothed rollers 4 in opposite directions. Use the protrusions on the surface of the toothed roller 4 to guide the movement of the combed yarn. The back of the toothed roller 4 also relies on the second bevel gear 8 with the first bevel gear 7 as the meshing support to be able to guide the movement of the yarn synchronously.

Then, three servo motors 6 are used to control the first bevel gear 7 installed at the front end of the toothed roller 4 to be meshed and connected with the second bevel gear 8, thereby rotating the longitudinally adjacent toothed rollers 4 in opposite directions, and the raised objects on the surface of the toothed roller 4 are used to guide the movement of the combed yarn.
