Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field that removes waste from core or former, specifically relates to a yarn tail cleaning mechanism based on spinning frame. BACKGROUND

[0002] After the spinning frame completes a production stage, there will be yarn tails remaining on the spindle, and the spindle foot is the main remaining area. The existing technology for yarn tail cleaning of the spinning frame has a redundant structure;

[0003] The utility model with the patent name of a yarn tail cleaning device for a spinning frame, which is disclosed in the patent with the publication number CN215713615U, uses a complex structure to drive the blade to cut and clean the yarn tail in the horizontal direction, and lacks vertical cutting function;

[0004] The utility model with the patent name of an automatic yarn tail cleaning device for a spinning frame, which is disclosed in the patent with the publication number CN221607471U, uses an X and Z dual-direction driving scheme to mainly cut and clean the yarn tail in the vertical direction. The structure is complex, and the cleaning efficiency is low. The existing technology has many concave or convex rough surfaces on the side wall of the spindle foot to increase the friction with the yarn. This scheme is not suitable for cutting the yarn tail on the rough surface, and the efficiency of cleaning the yarn tail is low. Therefore, there is an urgent need for a yarn tail cleaning mechanism based on a spinning frame to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a yarn tail cleaning mechanism based on a spinning frame to solve the technical problems of complex structure and low cleaning efficiency of the yarn tail cleaning scheme of the existing technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] The yarn tail cleaning mechanism based on the spinning frame is installed with a spindle body on the spindle base of the spinning frame, and the bottom of the spindle body is a spindle foot.

[0008] The yarn tail cleaning mechanism includes a blade mounting seat arranged on one side of the spindle foot. The blade mounting seat is close to one side of the spindle foot and is fixedly connected with a plurality of vertically linearly arranged blades. The blade includes an integrally formed curved blade area and a straight blade area. The side wall of the straight blade area is fixedly connected with the blade mounting seat, so that when the curved blade area cuts off the yarn tail wound on the spindle foot by itself transverse movement, the curved blade area can produce vertical elastic bending deformation after being resisted by the convex area on the spindle foot, generate a vertical cutting force, effectively cut the yarn tail wound horizontally on the spindle foot, and then make the yarn tail fall off from the spindle foot.

[0009] The blade mounting seat is driven by a horizontal driving component, which provides power for the horizontal movement of the blade mounting seat, and the blade mounting seat drives the horizontal movement of the blade.

[0010] As a preferred solution, the horizontal driving component includes a sliding groove separated by a baffle on the side wall of the spindle base, a screw linear driving component is installed in the sliding groove, a screw hole driven slider is horizontally and linearly driven on the screw linear driving component, and the screw hole driven slider is fixedly connected with the blade mounting seat.

[0011] As a preferred solution, the screw hole driven slider and the blade mounting seat are fixedly connected by an elastic connecting rod.

[0012] As a preferred solution, the elastic connecting rod can be elastically bent. When the blade cuts the yarn tail, if the resistance from the spindle foot to the direction of the blade mounting seat is too large, the elastic connecting rod will be slightly bent to reduce the friction and protect the blade from damage.

[0013] As a preferred solution, the distance between adjacent blades is 1.5-5mm, a vertical elastic deformation is generated in a curved blade area, which can quickly extrude the adjacent curved blade area to make the adjacent curved blade area also generate a vertical elastic deformation, thereby enhancing the cleaning efficiency of the yarn tail cleaning mechanism on the yarn tail.

[0014] As a preferred solution, the distance between adjacent blades is 3mm.

[0015] As a preferred solution, the thickness of all curved blade areas is less than the thickness of straight blade areas, so that the curved blade areas are more easily elastically deformed.

[0016] Advantages:

[0017] 1. When the curved blade area cuts the yarn tail wound on the spindle foot by horizontal movement, the curved blade area will generate a vertical elastic bending deformation after being resisted by the protruding area on the spindle foot, generating a vertical cutting force, so that the horizontally wound yarn tail on the spindle foot can be effectively cut, and the yarn tail can be effectively cleaned with a simple structure.

[0018] 2. This solution uses the curved blade area and the straight blade area to cut the yarn tail together. The straight blade area is not easily deformed and is suitable for high-intensity cutting, which can efficiently clean the yarn tail in combination with the non-parallel cutting effect of the curved blade area.

[0028] The yarn tail cleaning mechanism comprises a blade mounting seat 106 arranged on one side of the spindle leg 103; the blade mounting seat 106 is close to one side of the spindle leg 103 and is fixedly connected with a plurality of vertically linearly arranged blades 107; the blade 107 comprises two parts of an integral bending blade area 1071 and a straight blade area 1072, the side wall of the straight blade area 1072 is fixedly connected with the blade mounting seat 106, so that when the bending blade area 1071 cuts the yarn tail wound on the spindle leg 103 by itself transverse movement, the bending blade area 1071 can produce vertical elastic bending deformation after being resisted by the protruding area on the spindle leg 103, vertical cutting force is generated, the transversely wound yarn tail on the spindle leg 103 can be effectively cut, and then the yarn tail falls off from the spindle leg 103, so that the yarn tail cleaning effect is achieved; the bending blade area 1071 and the straight blade area 1072 are used to cut the yarn tail together, the straight blade area 1072 is not easy to deform, is suitable for cutting with great force, and can efficiently clean the yarn tail in cooperation with the cutting effect of the bending blade area 1071 in a non-parallel direction.

[0029] The horizontal driving part is drivingly connected with the blade mounting seat 106, so as to provide power for the transverse movement of the blade mounting seat 106, and then the blade mounting seat 106 drives the blade 107 to move transversely.

[0030] The horizontal driving part comprises a sliding groove separated by a baffle on the side wall of the spindle base 101, a screw linear driving part 104 is arranged in the sliding groove, a screw hole driven sliding block 105 is horizontally and linearly driven on the screw linear driving part 104, the screw hole driven sliding block 105 is fixedly connected with the blade mounting seat 106, and the motor in the screw linear driving part 104 is automatically controlled by using an external intelligent control device, so that the blade 107 can intelligently clean the yarn tail on the spindle leg 103 at a suitable time.

[0031] The screw hole driven sliding block 105 and the blade mounting seat 106 are fixedly connected by using an elastic connecting rod 108.

[0032] The elastic connecting rod 108 can be elastically bent, when the blade 107 cuts the yarn tail and the resistance to the blade mounting seat 106 from the spindle leg 103 is too large, the elastic connecting rod 108 is slightly bent to reduce the friction, and the blade 107 is protected from being damaged.

[0033] The distance between adjacent blades 107 is 3 mm, the vertical elastic deformation of one bending blade area 1071 can quickly extrude and affect the adjacent bending blade area 1071, so that the adjacent bending blade area 1071 also produces vertical elastic deformation, and the cleaning efficiency of the yarn tail cleaning mechanism on the yarn tail is enhanced.

[0034] The thickness of the curved blade region 1071 is less than the thickness of the straight blade region 1072, making the curved blade region 1071 more easily elastically deformed.
