Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, and in particular to a self-cleaning structure of a rotor spinning device, a textile machine and a self-cleaning operation method. Background Art

[0002] Rotor spinning is one of the free-end spinning methods. It is called rotor spinning because it uses a rotor to condense single fibers. Rotor spinning has high spinning speed, large winding capacity, good suitability for spinning low-grade cotton and waste cotton, and greatly improved working environment. The rotor spinning device is an important component to realize this process.

[0003] In the rotor spinning machine, the fed fiber strips are opened into single fibers by the rotating combing rollers covered with needle clothing, and transported to the inner wall of the high-speed rotating rotor with the air flow, forming a yarn tail in the condensation groove, and at the same time being twisted into yarn and led out, and directly wound into a bobbin. The main difference between rotor spinning and other free-end spinning methods is the different mechanisms and functions of condensation and twisting. After the single fiber enters the rotor of the rotor spinning machine, it is first sent to the inclined surface of the inner wall of the rotor. Due to the high surface speed of the inner wall of the rotor, the fibers are arranged parallel to the circumference of the inner wall. Under the action of centrifugal force, they slide into the condensation groove at the maximum diameter of the inner wall, where they are superimposed into annular whiskers. This is the condensation process of the fibers. During the condensation process, the fibers are arranged in a circumferential cycle to form the winding fibers of the air-spun yarn.

[0004] If impurities are left in the condensation groove of the rotor during the spinning process, the condensation of the yarn and the transfer of twist will be destroyed, making the spun yarn periodically uneven, with a wavelength of about the circumference of the rotor. In severe cases, broken ends will occur. Even if fine dust enters the condensation groove, it will gradually accumulate into larger particles, producing the same effect. In many embodiments of the prior art, an open spinning machine including a cleaning device for cleaning the spinning rotor is known. For example, DE 100 231 484 A1 describes an open spinning device for cleaning a rotor spinning machine by means of a movable maintenance unit. For this purpose, the maintenance unit includes a cleaning device, which includes a cleaning head, which includes a mechanical cleaning element, such as a scraper, or includes a compressed air nozzle. In order to clean the spinning rotor, the maintenance unit is located in front of the relevant spinning equipment, the rotor of the spinning machine is opened, the cleaning head is pushed toward the spinning rotor, and then the spinning rotor is cleaned. However, the cleaning device in the prior art must open the rotor of the spinning machine to interrupt spinning, and cannot be cleaned in a working state, which affects the spinning efficiency. Therefore, there is an urgent need for a device that can automatically clean the rotor spinning device when it is in normal working condition. Summary of the invention

[0005] The purpose of the present invention is to provide a self-cleaning structure of a rotor spinning machine, a textile machine and a self-cleaning operation method, which can clean the rotor without stopping the machine and have a good cleaning effect. At the same time, it can ensure the production efficiency of the textile machine with the self-cleaning structure and improve production benefits.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] The present invention provides a self-cleaning structure of a rotor spinning machine, comprising a spinning machine, wherein the spinning machine comprises a channel disk for conveying cotton fibers and a rotor, the rotor comprises a condensation groove for forming yarn, and also comprises a cleaning rod that can extend into and clean the condensation groove of the rotor when the rotor is in a working state, and a driving device for driving the cleaning rod to move.

[0015] In particular, the present application also provides a rotor self-cleaning operation method, including the rotor spinning machine self-cleaning structure as described above. When the rotor needs to be cleaned, the driving device drives the cleaning rod from an initial working position to a cleaning working position in contact with the condensation groove of the rotor in a rotating working state.

[0016] Optionally, after the cleaning rod completes cleaning of the rotating cup, the cleaning rod moves away from the rotating cup from the cleaning working position and returns to the initial working position.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Embodiment 1:

[0028] This embodiment describes a self-cleaning structure of a rotor spinning machine, such as Figure 1 , Figure 2 As shown, it includes a spinning device, which includes a channel disk 2 for conveying cotton fibers, a rotor 1, and the rotor 1 includes a condensation groove for forming yarn, and also includes a cleaning rod 4 that can be inserted into and clean the condensation groove of the rotor 1 when the rotor 1 is in a working state, and a driving device 5 for driving the cleaning rod 4 to move. The driving device 5 can automatically adjust the length of the cleaning rod 4 inserted into the condensation groove of the rotor 1 according to actual needs.

[0029] In order to guide the cleaning rod 4 when it penetrates into the rotor 1 in the working state, a guide channel 3 for the cleaning rod 4 to extend into the rotor 1 is provided on the channel disk 2, and the guide channel 3 is an arc segment for guiding the cleaning rod 4 to the condensation groove. Specifically, along the entry direction of the cleaning rod 4, the guide channel 3 includes a first end and a second end, and a guide portion is provided on the second end, and the guide portion has a guide arc surface. When the cleaning rod 4 enters from the first end to the second end, it bends and moves toward the condensation groove under the guidance of the guide arc surface. In this way, during the cleaning process, the cleaning rod 4 can be quickly and accurately guided to the condensation groove, quickly realize the cleaning of the condensation groove of the rotor spinning machine, and shorten the cleaning cycle.

[0030] In addition, in order to ensure that the cleaning rod 4 can penetrate into the rotating cup 1 and can be easily bent and guided in the guide channel 3, the cleaning rod 4 is preferably made of a flexible material.

[0031] The cleaning rod 4 can be used to control the cleaning of the rotor 1 according to the yarn condition in the condensation groove, or the cleaning frequency can be controlled by a preset cycle time. The two situations are as follows:

[0032] One is to set a control device and a detection device in the self-cleaning mechanism, the control device is used to control the action of the driving device 5, and the detection device is used to detect the residual amount of the material to be cleaned in the condensation groove of the rotor 1. The residual material to be cleaned refers to dust, impurities and short fibers, etc. The control device controls the frequency of the cleaning rod 4 entering the rotor 1 according to the detection result of the detection device. In other words, during the operation of the rotor spinning device, the residual amount of the material to be cleaned in the condensation groove of the rotor 1 is monitored in real time. When the cleanliness of the condensation groove is not high or there are abnormal conditions, it will cause abnormal changes in the residual amount of the material to be cleaned in the condensation groove. For example, it is detected that the material to be cleaned accumulated in the condensation groove exceeds a certain value. In this way, the condensation groove can be cleaned in a timely and effective manner.

[0033] The other method is to set a control device in the self-cleaning mechanism, in which a preset frequency for cleaning the rotating cup 1 is preset, that is, the control device controls the frequency of the cleaning rod 4 entering the rotating cup 1 according to the preset frequency. For example, if the rotating cup 1 is cleaned once every ten minutes, then the control device controls the cleaning rod 4 to enter the rotating cup 1 every ten minutes, so as to realize the timed and effective cleaning of the rotating cup 1.

[0034] Embodiment 2:

[0035] This embodiment provides a textile machine, which includes a plurality of rows of workstations arranged side by side, each of which includes the rotor spinning device self-cleaning structure as described in Example 1.

[0036] Equipped with the self-cleaning structure of the rotor spinning machine described in Example 1, the textile machinery can effectively clean the rotor 1 in the rotor spinning machine without stopping the machine and opening the spinning cup, thereby ensuring the spinning quality and effectively guaranteeing the production efficiency of the textile machinery with the above-mentioned self-cleaning mechanism, so that the production benefits are always maintained at a high level.

[0037] Embodiment 3:

[0038] The present embodiment provides a rotor self-cleaning operation method, which includes the rotor spinning box self-cleaning structure as described in Example 1, wherein the rotor spinning box self-cleaning structure includes a spinning box, the spinning box includes a channel disk 2 for conveying cotton fibers, and a rotor 1, the rotor 1 includes a condensation groove for forming yarn, and also includes a cleaning rod 4 that can be extended into and clean the condensation groove of the rotor 1 when the rotor 1 is in working state, and a driving device 5 for driving the cleaning rod 4 to move, and the driving device 5 can automatically adjust the length of the cleaning rod 4 extending into the condensation groove of the rotor 1 according to actual needs.

[0039] When the rotor cup 1 needs to be cleaned, the driving device 5 drives the cleaning rod 4 to move from the initial working position to the cleaning working position in contact with the condensation groove of the rotor cup 1 in the rotating working state. After the cleaning rod 4 completes the cleaning of the rotor cup 1, the cleaning rod 4 moves away from the rotor cup 1 from the cleaning working position and returns to the initial working position.

[0040] The rotor self-cleaning operation method of this embodiment controls the cleaning rod 4 to extend into the guide channel 3 in the rotor 1 when cleaning the rotor 1. The guide channel 3 includes a first end and a second end along the entry direction of the cleaning rod 4. The second end is provided with a guide portion. The guide portion in this embodiment has a guide arc surface. This method controls the cleaning rod 4 to enter from the first end to the second end. The cleaning rod 4 made of flexible material bends and moves toward the condensation groove under the guidance of the guide arc surface. During the cleaning process, the cleaning rod 4 can be quickly and accurately guided to the condensation groove and contact the inner wall of the condensation groove, quickly achieving effective cleaning of the condensation groove, shortening the cleaning cycle and improving the cleaning efficiency. Of course, the guide portion in other embodiments may also be a guide groove, a guide hole, etc. As long as the cleaning rod 4 is guided to the inner wall of the condensation groove and the condensation groove is effectively cleaned by the rotation of the rotor, it is within the protection scope of the present invention.

[0041] The rotor self-cleaning operation method of this embodiment realizes the cleaning control of the rotor 1 condensation groove by the cleaning rod 4. The method can be controlled according to the residual amount of the object to be cleaned in the condensation groove, or the cleaning frequency can be controlled by a preset cycle time. The two control methods are as follows:

[0042] One is to control the action of the driving device 5 by detecting the residual amount of the material to be cleaned in the condensation groove of the rotor 1, and then the control device controls the frequency of the cleaning rod 4 entering the rotor 1 according to the detection result of the detection device by detecting the residual amount of the material to be cleaned in the condensation groove of the rotor 1. In other words, during the operation of the rotor spinning device, the residual amount of the material to be cleaned in the condensation groove of the rotor 1 is monitored in real time. When the cleanliness of the condensation groove is not high or there is an abnormal situation, it will cause an abnormal change in the amount of the material in the condensation groove. In this way, the condensation groove can be cleaned in a timely and effective manner.

[0043] The other is to pre-configure the cleaning frequency of the rotating cup 1 and perform regular cleaning. A control device is set in the self-cleaning mechanism, and the control software of the control device is preset with a preset frequency for cleaning the rotating cup 1, that is, the control device controls the frequency of the cleaning rod 4 entering the rotating cup 1 according to the preset frequency. For example, if the cleaning interval of the rotating cup 1 is set to be 10 minutes, then the control device controls the cleaning rod 4 to enter the rotating cup 1 every 10 minutes, so as to achieve regular and effective cleaning of the rotating cup 1.

[0044] In addition, regarding the material selection of the cleaning rod 4 in the above embodiment, the cleaning rod 4 used in the present application is a consumable material, and the cleaning rod 4 is flexible but has a certain rigidity, such as a resin material such as high molecular weight polyethylene, polypropylene, or a rubber material, nylon material, etc. With each cleaning process, the cleaning rod 4 can contact the inner wall of the condensation groove, and the end part will be worn away. After each cleaning, the cleaning rod 4 will be fed and supplied to ensure that the cleaning plate 4 can contact the inner wall of the condensation groove and clean the condensation groove. Of course, the cleaning rod 4 can also be made of other wear-resistant materials, and it can be maintained or replaced after a certain period of time.

[0045] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
