Description

Technical Field

[0001] This application relates to the field of yarn breakage treatment technology, and in particular to a yarn breakage adsorption device for rotor spinning machines. Background Technology

[0002] Rotor spinning machines, with their advantages of high spinning speed, large roll capacity, and good adaptability to spinning low-grade cotton and waste cotton, have replaced traditional ring spinning machines and become the mainstay of current spinning technology. They are the most mature, widely used, and economically and socially beneficial spinning form among new spinning technologies. When using a vacuum-type rotor spinning machine, a broken yarn adsorption device is required.

[0003] A search revealed that publication number CN219603788U discloses a device for adsorbing broken yarn on a rotor spinning machine. First, the blower head is held and moved to stretch the corrugated tube, pointing towards the yarn assembly outlet. Then, the ventilation unit introduces airflow into the first duct. The airflow blows out through the first duct, blowing away the broken yarn on the yarn assembly to keep it clean. Simultaneously, the airflow enters a high-pressure fine tube along a second duct and is ejected. The faster airflow then drives the slower airflow, causing the airflow around the adsorption port to move with the airflow ejected from the high-pressure fine tube. This process collects the broken yarn carried by the airflow from the first duct into the adsorption cylinder, preventing it from sticking to the yarn assembly or scattering in the air.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] This device absorbs broken yarns without disturbing the yarn bundles by slowing down the airflow, but it lacks a dust removal structure, thus failing to effectively filter fine dust and release clean air, reducing its practicality. Utility Model Content

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a device for adsorbing broken yarn in a rotor spinning machine. (Refer to...) Figures 1 to 5 The spinner spinning machine yarn breakage adsorption device includes an air duct 1, an air pump 2, a circular hood 3, a first circular mesh frame 4, a feeding pipe 5, a collection tank 6, and a cleaning component 7.

[0036] The air pump 2, in conjunction with the air duct 1, is used to generate airflow and extract broken yarns from the yarn assembly. The circular hood 3 is used to separate broken yarns and fine dust. The first circular mesh frame 4 is used to adsorb broken yarns. The cleaning component 7 is used to peel the broken yarns on the first circular mesh frame 4 into the feed pipe 5. The feed pipe 5 is used to guide the broken yarns into the collection tank 6. The collection tank 6 is used to store broken yarns and fine impurities for further filtration.

[0037] The cleaning assembly 7 includes a DC motor 71, a rotating frame 72, a hollow support 73, a connecting ear plate 74, and a cleaning roller 75. The DC motor 71 is mounted on the outside of the circular shroud 3. The rotating frame 72 is mounted on the outside of the output end of the DC motor 71 and is rotatably connected to the inside of the circular shroud 3. The hollow support 73 is fixedly connected to the outside of the rotating frame 72. The connecting ear plate 74 is fixedly connected to the inside of the hollow support 73. The cleaning roller 75 is rotatably connected to the opposite side of the connecting ear plate 74 and is used to abut against the first circular mesh frame 4.

[0038] A precision square filter plate 8 is also installed on the side of the circular hood 3 away from the air duct 1. The precision square filter plate 8 is used to adsorb fine dust in the broken yarn and bring out clean air.

[0039] The bottom of the circular hood 3 is also provided with a hinge plate 9 and a discharge baffle 10. The hinge plate 9 is installed on one side of the bottom of the circular hood 3 and is hinged to the bottom of the discharge baffle 10. The top of the discharge baffle 10 is slidably connected to the surface of the first circular grid frame 4.

[0040] A tension spring 11 is also installed on one side of the discharge baffle 10. The two sides of the tension spring 11 are fixedly connected to the surfaces of the discharge baffle 10 and the circular wind cover 3, respectively.

[0041] A second circular filter plate 12 is also installed on the inner bottom of the collection tank 6. The second circular filter plate 12 is used to support broken yarn and separate fine dust.

[0042] A sealed box cover 13 is also installed on the outside of the circular wind cover 3.

[0043] Two sets of hollow supports 73 are provided, and the two sets of hollow supports 73 are symmetrically distributed on both sides of the first circular grid 4.

[0044] The usage process of the rotor spinning machine yarn breakage adsorption device in this embodiment is roughly as follows:

[0045] In use, the air duct 1 is installed around the yarn assembly. Then, the air pump 2 is started to generate airflow. The air duct 1 draws the loose yarn attached to the yarn assembly along the inner wall of the duct into the circular hood 3, keeping the yarn assembly clean. The loose yarn entering the circular hood 3 directly contacts the first circular mesh frame 4. The first circular mesh frame 4 firmly adsorbs some of the loose yarn onto its surface, while the other part of the yarn is concentrated on the feed baffle 10. Excess dust and air pass through the first circular mesh frame 4 and are blown directly onto the outer precision square filter plate 8. The precision square filter plate 8 adsorbs the dust and releases the clean air inside the circular hood 3 to the outside. Then, the outer DC motor 71 is started to drive the rotating frame 72 to rotate. The rotating frame 72 drives the hollow support 73 to rotate. The lower end of the hollow support 73... The cleaning roller 75 adheres to the surface of the first circular mesh frame 4 and rotates synchronously, thereby peeling off the broken yarn on the surface. During this process, the hollow support 73 abuts against the feed baffle 10, causing the feed baffle 10 to rotate downward along the hinge plate 9. The hollow support 73 then sweeps out the broken yarn gathered on the feed baffle 10 during the rotation. Afterward, the feed baffle 10 recovers under the reaction force of the tension spring 11 and blocks again. The swept broken yarn enters the collection tank 6 along the feed pipe 5. Under the action of gravity, the remaining fine dust falls into the inside of the collection tank 6 through the second circular filter plate 12, while the broken yarn remains on the second circular filter plate 12 to facilitate subsequent collection by the staff, thereby achieving the effect of adsorbing, collecting and filtering broken yarn synchronously.

[0046] The beneficial technical effects of the rotor spinning machine yarn breakage adsorption device according to the embodiments of this application are roughly as follows:

[0047] This device adds a circular hood 3 around the air guide pipe 1. Broken yarn blown in by the air guide pipe 1 is blown into the circular hood 3 and blown directly towards the first circular mesh frame 4. The broken yarn is adsorbed on the first circular mesh frame 4, while the air passes through the first circular mesh frame 4 and blows directly towards the precision square filter plate 8. The precision square filter plate 8 adsorbs dust and releases clean air, while the broken yarn adsorbed on the first circular mesh frame 4 is poured into the collection tank 6 by the sliding action of the cleaning roller 75. The second circular filter plate 12 completes the reseparation of dust and broken yarn, thus facilitating the collection of broken yarn.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
