Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a cotton guiding and impurity removal device for a drawing frame. Background Technology

[0002] In the textile industry, the drawing frame is one of the key processing equipment. Its function is to combine and draft multiple cotton slivers, making the fibers in the sliver more parallel and straight, thereby improving the quality and uniformity of the sliver and providing good raw materials for subsequent spinning processes. However, during the production and transportation of cotton slivers, various impurities, such as cotton leaves, cotton husks, dust, and short fibers, are inevitably mixed in. The presence of these impurities not only affects the quality of the cotton sliver, leading to problems such as yarn breakage and defects, reducing the strength and uniformity of the yarn, but also affects the efficiency of the entire textile production process and the stability of product quality.

[0003] Currently, existing drawing frames have certain limitations in cotton guiding and impurity removal. Some drawing frames only use simple mechanical impurity removal methods, such as manual removal, which are effective at removing larger particles of impurities, but are ineffective at removing tiny impurities and lint, resulting in unsatisfactory impurity removal. Furthermore, some impurity removal devices are not tightly integrated with the cotton guiding device, failing to remove impurities efficiently and in real time during the cotton guiding process. This leads to the continuous accumulation of impurities in the cotton fibers during transport, further affecting product quality. Therefore, this paper proposes a cotton guiding and impurity removal device for drawing frames to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 3 The drawing frame cotton guide and impurity removal device in this embodiment includes a base 1 and two support plates 2 fixedly connected to the top of the base 1. The two support plates 2 are respectively arranged on the left side and the right side of the top of the base 1. The inner side of the base 1 is provided with impurity removal components.

[0026] Please see Figure 1In this embodiment, the impurity removal component includes a negative pressure fan 3 fixedly connected to the inner bottom wall of the base 1. A fixed pipe 4 is fixedly connected to the exhaust end of the negative pressure fan 3. A collection box 5 is fixedly connected to the top end of the fixed pipe 4. A connecting pipe 6 is fixedly connected to the top end of the collection box 5. A wind collection hood 7 is fixedly connected to the top end of the connecting pipe 6.

[0027] A cotton guiding assembly for guiding cotton is provided on the left side of the left support plate 2. The cotton guiding assembly includes a motor 8 fixedly connected to the left side of the left support plate 2. A transmission rod 9 is fixedly connected to the output shaft of the motor 8. A cotton guiding roller 10 is fixedly connected to the outer side of the transmission rod 9. A transmission gear 11 is fixedly connected to the right end of the transmission rod 9. A driven gear 12 meshes with the top of the transmission gear 11. A driven rod 13 is fixedly connected to the inner side of the center of the driven gear 12. An anti-bias pressure roller 14 is fixedly connected to the left end of the driven rod 13. A support rod 15 is fixedly connected to the left side of the anti-bias pressure roller 14.

[0028] Specifically, motor 8 is a servo motor, and a motor frame is fixedly connected to the outside of motor 8. The motor frame is fixedly connected to the left side of the left support plate 2 by bolts.

[0029] It should be noted that the motor 8 is fixedly connected to a motor frame. This fixing method can ensure that the motor 8 remains stable during operation, reduce vibration, avoid transmission errors and equipment failures caused by the vibration of the motor 8, and improve the working reliability and stability of the entire cotton guiding and impurity removal device.

[0030] Specifically, the right end of the transmission rod 9 passes through the left side wall of the left support plate 2, the right side wall of the left support plate 2, the mounting hole of the cotton guide roller 10, the left side wall of the right support plate 2, and the right side wall of the right support plate 2 in sequence, and extends to the inner side of the center of the transmission gear 11 and is fixedly connected to the transmission gear 11.

[0031] It should be noted that this through-connection method enables the transmission rod 9 to simultaneously drive the cotton guide roller 10 and the transmission gear 11 to rotate, thus achieving effective power transmission and ensuring the normal cotton guiding function of the cotton guide roller 10 and the subsequent linkage effect of the driven gear 12 being driven by the transmission gear 11.

[0032] Specifically, the left end of the driven rod 13 passes through the right side wall and the left side wall of the right side support plate 2 in sequence and is fixedly connected to the anti-deviation pressure roller 14, and the left end of the support rod 15 is rotatably connected to the right side wall of the left side support plate 2.

[0033] It should be noted that the connection method of the driven rod 13 through the right support plate 2 ensures that the driven rod 13 can stably drive the anti-biased pressure roller 14 to rotate, while the rotational connection of the support rod 15 to the right side wall of the left support plate 2 provides additional support for the anti-biased pressure roller 14, ensuring the stability and balance of the anti-biased pressure roller 14 during rotation, preventing the anti-biased pressure roller 14 from shaking or deviating during operation, thereby better achieving the anti-biased pressure effect on cotton fibers.

[0034] Specifically, the surface of the cotton guide roller 10 is provided with several ventilation holes, the surface of the anti-bias roller 14 is provided with an insulating ceramic layer, and the inner side of the anti-bias roller 14 is provided with an electrostatic generator 16.

[0035] It should be noted that the ventilation holes on the surface of the cotton guide roller 10 allow the negative pressure airflow generated by the impurity removal component to pass through, thereby achieving the adsorption and removal of impurities in the cotton fibers during the cotton guiding process. The insulating ceramic layer on the surface of the anti-bias roller 14 can play an insulating and protective role, preventing the static electricity generated by the static generator 16 from interfering with or damaging other components. At the same time, the static electricity generated by the static generator 16 can adsorb tiny impurities and lint in the cotton fibers, further improving the impurity removal effect.

[0036] Specifically, a recycling box 501 is placed inside the collection box 5. An opening is provided at the bottom of the inside of the recycling box 501, and a ventilation interception net 502 is fixedly connected to the inside of the opening.

[0037] It should be noted that the recycling box 501 is used to collect impurities that enter the collection box 5 from the air collecting hood 7 and the connecting pipe 6, while the ventilation interception net 502 allows airflow to pass through while intercepting impurities, preventing impurities from entering the negative pressure fan 3, protecting the normal operation of the negative pressure fan 3, and extending its service life.

[0038] Specifically, the front of the collection box 5 is hinged with a box-retrieving door, and the four corners of the bottom of the collection box 5 are fixedly connected with support legs, and the bottom of the support legs is fixedly connected to the inner bottom wall of the base 1.

[0039] It should be noted that the design of the retrieval door makes it convenient for operators to periodically remove the recycling box 501 and clean up the collected impurities, while the support legs serve to support the collection box 5.

[0040] Specifically, a fixing opening is provided on the top of the inner side of the base 1, and the air collecting cover 7 is fixedly connected to the inner side of the fixing opening.

[0041] It should be noted that this connection method allows the air collecting hood 7 to be stably fixed on the base 1, ensuring that the airflow and impurities passing around the cotton guide roller 10 can be effectively collected during the impurity removal process and guided to the connecting pipe 6 and the impurity collection box 5.

[0042] Specifically, a fan maintenance door is hinged to the front of the base 1, and an operation panel is fixedly connected to the left side of the base 1.

[0043] It should be noted that the fan maintenance door facilitates the maintenance and repair of the negative pressure fan 3 inside the base 1 by the operator, such as cleaning the dust inside the fan and checking the operating status of the fan. The control panel is used to control the operation of the entire cotton guiding and impurity removal device of the drawing frame. The operator can set parameters such as the speed of the motor 8 and the wind force of the negative pressure fan 3 through the control panel to achieve precise control of the cotton guiding and impurity removal process.

[0044] The working principle of the above embodiments is as follows:

[0045] The operator starts the motor 8 through the control panel. The motor 8 starts to rotate as a power source. Since the output shaft of the motor 8 is fixedly connected to the transmission rod 9, the rotation of the motor 8 drives the transmission rod 9 to rotate synchronously. The cotton guide roller 10 is fixedly connected to the outside of the transmission rod 9. As the transmission rod 9 rotates, the cotton guide roller 10 also starts to rotate. The cotton fibers to be processed are introduced between the cotton guide roller 10 and the anti-bias roller 14. The rotation of the cotton guide roller 10 drives the cotton fibers forward through friction, thus realizing the cotton guiding function.

[0046] Meanwhile, a transmission gear 11 is fixedly connected to the right end of the transmission rod 9. When the transmission rod 9 rotates, it drives the transmission gear 11 to rotate synchronously. The transmission gear 11 meshes with the driven gear 12, so the driven gear 12 rotates. A driven rod 13 is fixedly connected to the inner side of the center of the driven gear 12. The rotation of the driven gear 12 drives the driven rod 13 to rotate synchronously. An anti-biased pressure roller 14 is fixedly connected to the left end of the driven rod 13. The rotation of the driven rod 13 drives the anti-biased pressure roller 14 to rotate. The rotation direction of the anti-biased pressure roller 14 is opposite to that of the cotton guide roller 10. The two work together to stably clamp the cotton fibers in the middle and transport them forward. At the same time, the static electricity generated by the insulating ceramic layer on the surface of the anti-biased pressure roller 14 and the static electricity generator 16 on the inner side can adsorb tiny impurities and lint in the cotton fibers, assisting in the impurity removal process.

[0047] During the cotton guiding process, the operator simultaneously starts the negative pressure fan 3. After the negative pressure fan 3 starts working, its exhaust end generates negative pressure airflow. The negative pressure airflow forms suction at the air collection hood 7, which sucks in the impurities raised in the cotton fibers during the cotton guiding process as well as the impurities in the airflow that enter through the ventilation holes on the surface of the cotton guiding roller 10 into the air collection hood 7. The impurities enter the impurity collection box 5 through the connecting pipe 6 with the airflow. The airflow enters the bottom of the recycling box 501 through the ventilation interception net 502, while the impurities are intercepted by the ventilation interception net 502 and collected in the recycling box 501.

[0048] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
