Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to an automatic yarn spindle changing device. Background Technology

[0002] As an important part of traditional manufacturing, the textile industry's products are widely used in many fields such as clothing, home furnishings, and industry.

[0003] In textile production, the spindle, as a key component in spinning, directly impacts the entire production process through the efficiency and quality of its replacement. Traditional spindle replacement relies primarily on manual operation. Workers must manually stop the spinning machine and, relying on experience and physical strength, disassemble the used spindle and install a new one. This manual method has several drawbacks. Firstly, with the continuous expansion of textile enterprises and the increasing number of production equipment, the frequency of spindle replacement also increases. The large amount of manual replacement operations consumes significant time and labor costs, severely hindering production efficiency. Secondly, manual spindle replacement struggles to guarantee precision and consistency. Due to differences in worker skill, physical strength, and attention, inaccurate spindle placement and insecure clamping can easily occur during disassembly and installation. These problems can lead to uneven yarn winding and unstable tension during winding, resulting in yarn breakage and textile quality defects. Therefore, we propose an automatic spindle replacement device to address this issue. Utility Model Content

The device utilizes a hinged connection between two sets of clamping rods and a connecting plate, and a connecting rod that hinges between the connecting plate and the two sets of clamping rods. As the fixed block moves upward, it moves the two sets of clamping rods and the arc-shaped clamping plate closer together. Conversely, as the fixed block moves downward, it moves the two sets of clamping rods and the arc-shaped clamping plate away from each other, facilitating the clamping, fixing, and releasing of the spinning spindle. This allows for precise clamping of the spinning spindle. During clamping, the arc-shaped clamping plate closely adheres to the surface of the spinning spindle, ensuring that the spinning spindle does not shake, shift, or fall during replacement. This guarantees the accuracy of the spinning spindle's installation position, avoiding problems such as yarn tangling and breakage caused by improper installation. It improves the quality stability of textile products, achieves automation, greatly reduces the labor intensity of workers, improves the working environment, and increases worker satisfaction and productivity.

Driving the electric push rod facilitates the movement of the support frame, causing the gripper assembly to move left and right, enabling the replacement of other spinning spindle bodies. The long plates on both sides of the connecting plate move downwards, pressing the pressure plate. At this time, the pressure plate drives the top connecting shaft, sliding plate, and inclined block one downwards, causing the sliding plate to press the spring one. Through the reset of two sets of springs two, the inclined surfaces of the two sets of inclined blocks two are always in contact with the inclined surface of inclined block one, allowing the two sets of insert rods to disengage from the inside of the spinning spindle body. This achieves rapid installation and disassembly of the spinning spindle without requiring large-scale modification or replacement of the entire device, greatly improving the equipment's versatility and adaptability, reducing the enterprise's equipment procurement and maintenance costs, and facilitating the replacement of spinning spindle bodies in different positions.
