Description

Technical Field

[0002] The doffing process, a crucial step in the spinning workshop production process, plays a vital role in overall production efficiency and product quality. In traditional production models, this task primarily relies on manual operation, which is not only labor-intensive but also inefficient and physically demanding. With continuous technological advancements, automatic doffing spinning machines have become widely used in the textile industry. These machines employ an automatic drive system with a precision robotic arm as the gripping mechanism. During operation, the drive wheels operate precisely according to a pre-programmed sequence, driving the robotic arm to flexibly grasp, transport, and place the yarn. This significantly reduces manual labor input, dramatically improves production efficiency, effectively alleviates the pressure on textile companies to maintain a large workforce, saves valuable human resources, and simultaneously propels the textile industry towards automation and intelligentization.

[0003] Existing automatic doffing machines cause cotton lint, fibers, and other debris to scatter from the surface of the yarn during doffing, which can entangle equipment parts, leading to malfunctions, increasing dust concentration in the workshop, and making cleaning more difficult.

The bottom of the screw 21 is fixedly connected to the output end of the motor 24. The motor 24 drives the screw 21 to rotate, thereby driving the lifting block 22 to move up and down, and then driving the cleaning brush 23 to move to clean the filter screen 20.

[0028] In one embodiment, specifically: a U-shaped groove 25 is provided in the middle of the front surface of the base 11, and a receiving box 26 is slidably connected to the inner sidewall of the U-shaped groove 25; a receiving port 27 is provided at the bottom of the front surface of the frame 12; the upper part of the outer sidewall of the receiving box 26 is slidably connected to the inner sidewall of the receiving port 27; buffer dampers 28 are fixedly connected to the four corners of the inner bottom wall of the receiving box 26; a movable base plate 29 is fixedly connected to the top of the four buffer dampers 28; and a buffer pad 30 is fixedly connected to the upper surface of the movable base plate 29. The buffer dampers 28 and the buffer pad 30 buffer the impact force when the yarn falls, thereby reducing the damage to the yarn and protecting the receiving box 26 from being easily deformed or broken.

[0032] In one embodiment, specifically: a cleaning port 39 is provided on the rear part of the lower surface of the collection box 14, and a sealing door 40 is installed on the inner side wall of the cleaning port 39. By opening the sealing door 40, it is convenient to clean out the cotton wool, fibers and other debris collected in the collection box 14 from the cleaning port 39.

[0033] In one embodiment, specifically: a fixing hole 41 is provided at the center of the top of the front surface of the frame 12; a second electric push rod 42 is fixedly connected to the inner wall of the fixing hole 41; a T-shaped groove 43 is provided in the middle of the inner top wall of the frame 12; a T-shaped block 44 is slidably connected to the inner wall of the T-shaped groove 43; a sliding block 45 is fixedly connected to the bottom of the T-shaped block 44; the output end of the second electric push rod 42 is fixedly connected to the center of the front surface of the sliding block 45; a third electric push rod 46 is fixedly connected to the center of the lower surface of the sliding block 45; and a clamping mechanism 47 is fixedly connected to the output end of the third electric push rod 46. The electric push rod 42 is installed in the fixing hole 41 at the center of the top of the front surface of the frame 12. Its output end pushes the sliding block 45. The sliding block 45 slides in the T-groove 43 on the inner top wall of the frame 12 through the T-shaped block 44, realizing horizontal movement. The third electric push rod 46 is installed at the center of the lower surface of the sliding block 45. Its output end is connected to the clamping mechanism 47. The extension and retraction of the third electric push rod 46 controls the vertical movement of the clamping mechanism 47. Through the coordinated movement of the second electric push rod 42 and the third electric push rod 46, the position of the clamping mechanism 47 is precisely controlled, so that it can accurately grasp and transfer the yarn.

[0034] In one embodiment, specifically: protective plates 48 are installed on both sides of the frame 12, and support legs 49 are fixedly connected to the four corners of the lower surface of the base 11. The protective plates 48 prevent cotton lint, fibers and other debris falling from the surface of the yarn from flying around and affecting the environment; the support legs 49 support the base 11, thereby increasing the stability of the entire device.

[0035] Working principle or structural principle: When the automatic doffing machine is working, the exhaust fan 17 is started, generating suction through the air inlet 15 on the rear surface of the collection box 14. During the doffing process, cotton lint, fibers, and other debris falling off the surface of the yarn are sucked into the collection box 14 by the suction generated by the exhaust fan 17. When the debris passes through the filter screen 20, it is intercepted by the filter screen 20, while the air continues to be discharged through the filter screen 20, achieving preliminary separation of debris and air. When it is necessary to clean the filter screen 20, the motor 24 is started, and the motor 24 drives the screw 21 to rotate. The screw 21 is threadedly connected to the lifting block 22, and the second limiting strips 38 on both sides of the lifting block 22 slide within the second limiting grooves 37 on the inner side wall of the collection box 14, restricting the rotation of the lifting block 22 so that it can only move up and down along the screw 21. As the screw 21 rotates, the lifting block 22 drives the cleaning brush 23 to move up and down. The front surface of the cleaning brush 23 adheres to the rear surface of the filter screen 20, cleaning the filter screen 20 and sweeping the debris intercepted on the filter screen 20 to the bottom of the collection box 14. After cleaning, the lower surface of the collection box 14 is opened. The sealing door 40 at the cleaning port 39 allows debris to be discharged from the collection box 14. The clamping mechanism 47, controlled by the second electric push rod 42 and the third electric push rod 46, moves to a suitable position to grab the yarn. After grabbing, the yarn is moved above the receiving box 26 by the telescopic movement of the second and third electric push rods 42 and 46. The yarn then falls into the receiving box 26. The buffer dampers 28 at the four corners of the bottom wall of the receiving box 26 and the buffer pads 30 on the movable base plate 29 effectively buffer the impact force when the yarn falls. To reduce damage to the fine yarn and protect the take-up box 26 from easy deformation or breakage; when the fine yarn collected by the take-up box 26 reaches a certain amount and needs to be removed, the first electric push rod 31 is activated. The output end of the first electric push rod 31 pushes the strip plate 32, and the strip plate 32 pushes the take-up box 26. The first limiting strips 34 on both sides of the lower part of the take-up box 26 slide in the first limiting groove 33 on the inner side wall of the U-shaped groove 25, ensuring that the take-up box 26 slides smoothly out along the U-shaped groove 25, which facilitates the removal of the fine yarn and the cleaning and maintenance of the take-up box 26.

[0036] In summary, this invention utilizes the operation of an exhaust fan to generate suction at the air inlet, drawing debris into the collection box. A filter screen intercepts the debris, achieving separation of air and debris. A motor-driven screw automatically cleans the filter screen with a cleaning brush, preventing clogging and ensuring stable suction. The cleaned debris is discharged from the cleaning port, reducing dust concentration in the workshop, minimizing debris entanglement on equipment components, lowering the risk of equipment failure, and reducing the cleaning burden. Furthermore, the buffer damper and cushioning pad inside the collection box effectively cushion the impact of falling yarn, reducing quality degradation caused by impact. This also reduces the probability of deformation and breakage of the collection box, extending its service life, lowering equipment maintenance costs, and ensuring the quality of the yarn products.
