Description

Technical Field

[0001] This utility model relates to the field of chemical fiber technology in the cotton spinning industry, and in particular to a yarn feeding device for cotton spinning and chemical fiber instruments. Background Technology

[0002] In the quality inspection process of cotton spinning enterprises and chemical fiber production enterprises, yarn and chemical fiber testing instruments need to be equipped with automatic yarn feeding devices to achieve automated batch testing and improve production inspection efficiency.

[0003] Currently, the yarn feeding device of yarn and chemical fiber testing instruments has a complex structure, requiring multiple components to work together. This places high demands on structural and electrical control design. More importantly, it suffers from low yarn feeding efficiency and reliability, which greatly reduces the working efficiency of automated cotton spinning and chemical fiber instruments and results in a poor user experience. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies, the purpose of this utility model is to provide a yarn feeding device for cotton spinning and chemical fiber instruments.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A yarn feeding device for cotton spinning and chemical fiber instruments includes: a housing, a sliding mechanism that can move up and down installed inside the housing, a rotatable robotic arm installed on the sliding mechanism, and a yarn-grabbing mechanism installed at the end of the robotic arm.

[0007] The sliding mechanism includes: a linear cylinder installed inside the housing, a slider mounted on the linear cylinder, and a robotic arm mounted on the slider.

[0008] The upper and lower supports of the linear cylinder are respectively installed on the upper and lower parts of the housing, and the linear cylinder is installed inside the upper and lower supports of the linear cylinder.

[0009] The linear cylinder is provided with an inclined angle between itself and the housing to control the front-to-back span between the yarn gripping position and the yarn releasing position. The inclined angle ranges from 0° to 10°.

[0010] A swing cylinder is mounted on the sliding mechanism, and the robotic arm is mounted on the swing cylinder.

[0011] The swing cylinder is mounted on the sliding mechanism via a swing cylinder bracket.

[0012] The wire-retrieving mechanism includes: a wire-retrieving cylinder installed at the end of the robotic arm, and an opening and closing clamp is installed on the wire-retrieving cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention provides a yarn feeding device for cotton and chemical fiber spinning instruments. By incorporating a single-stroke yarn picking mechanism, the reliability of yarn clamping and releasing is significantly improved, effectively reducing the probability of yarn clamping failure. The use of a swing cylinder and a steel robotic arm greatly enhances the accuracy of the yarn picking and releasing positions, maintaining the correct position even after repeated yarn picking and releasing. Furthermore, the inclusion of a pneumatic linear cylinder allows for autonomous adjustment of the yarn feeding speed, significantly improving the stability and efficiency of yarn feeding, reducing human intervention in the testing process, and substantially saving labor costs. This invention effectively improves the accuracy of yarn feeding and can strongly promote the automation of yarn and chemical fiber testing instruments. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0019] like Figure 1 , 2 As shown, this utility model provides a yarn feeding device for cotton spinning and chemical fiber instruments, including: a housing 4, a sliding mechanism that can move up and down is installed inside the housing 4, a rotatable mechanical arm 3 is installed on the sliding mechanism, and a yarn picking mechanism 2 for grasping yarn is installed at the end of the mechanical arm 3.

[0020] Specifically, the sliding mechanism includes: a linear cylinder 5 installed inside the housing 4, a slider mounted on the linear cylinder 5, and the robotic arm 3 mounted on the slider. An upper linear cylinder support 1 and a lower linear cylinder support 9 are respectively installed on the upper and lower parts of the housing 4, and the linear cylinder 5 is installed within the upper linear cylinder support 1 and the lower linear cylinder support 9. The linear cylinder 5 is fixed to the housing 4 by the upper linear cylinder support 1 and the lower linear cylinder support 9. A cable chain 8 is installed on the inner wall of the housing 4 for moving up and down with the robotic arm and for wrapping cables and air pipes.

[0021] Preferably, an inclined angle is provided between the linear cylinder 5 and the housing 4 to control the front-to-back span between the yarn gripping position and the yarn releasing position, and the inclined angle ranges from 0° to 10°. A swing cylinder 6 is mounted on the sliding mechanism, and the robotic arm 3 is mounted on the swing cylinder 6. The swing cylinder 6 is mounted on the sliding mechanism via a swing cylinder bracket 7.

[0022] The distance between the yarn-grabbing station and the yarn-feeding station can be controlled by adjusting the swing angle of the swing cylinder; the yarn-feeding stroke of the device can be changed by changing the length of the linear cylinder 5; and the front-to-back span between the yarn-grabbing position and the yarn-releasing position can be controlled by changing the installation tilt angle of the linear cylinder 5. The entire yarn-feeding trajectory of the device can be described as: a left-to-right swinging arc trajectory + linear motion + a left-to-right swinging arc trajectory.

[0023] In addition, the wire-retrieving mechanism 2 includes a wire-retrieving cylinder installed at the end of the robotic arm 3, and an opening and closing clamp is installed on the wire-retrieving cylinder.

[0024] The principle and working process of this utility model:

[0025] like Figure 1 As shown, firstly, the swing cylinder 6 slides to the initial position at the top of the linear cylinder 5, at which point the clamp of the wire taking mechanism 2 is in the open state; then as... Figure 2 As shown, the swing cylinder 6 starts to swing, and the yarn taking mechanism 2 swings to the yarn clamping position. The clamp of the yarn taking mechanism 2 closes and clamps the yarn. Next, the yarn taking mechanism 2, which has clamped the yarn, swings back to the initial position through the swing cylinder 6 and guides the yarn through the linear cylinder 5 to slide to the bottom. Finally, the yarn taking mechanism 2 swings to the yarn releasing position, and the clamp of the yarn taking mechanism 2 opens to let the yarn fall off. At the same time, the fallen yarn is sucked away by the yarn suction device of the detection instrument. At this time, the yarn is sent to the corresponding detection slot, and the entire yarn guiding process ends.

[0026] It will be apparent to those skilled in the art that the above specific embodiments are merely preferred embodiments of the present utility model. Therefore, any improvements or modifications that may be made by those skilled in the art to certain parts of the present utility model still embody the principles of the present utility model and achieve the purpose of the present utility model, and all fall within the scope of protection of the present utility model.
