Description

Technical Field

[0001] This utility model relates to the field of viscose yarn processing technology, and in particular to a carding device for viscose yarn with a cleaning mechanism. Background Technology

[0002] Viscose yarn is a type of yarn made from viscose fibers. Viscose fibers are made from natural cellulose as raw material, which undergoes processes such as alkalization, aging, and sulfonation to produce soluble cellulose xanthate, which is then dissolved in a dilute alkali solution to form viscose, and finally spun using a wet spinning process. Carding is an important step in the processing of viscose yarn, and a carding device is used.

[0003] Chinese Patent Application Publication No. CN216404655U discloses a carding device for cotton yarn processing, including a carding frame, a cleaning mechanism, and a feed hopper. The top of the carding frame has a maintenance channel and a feed trough. A top cover plate is installed along the inner edge of the maintenance channel, and a feed hopper is installed along the inner edge of the feed trough. The cleaning mechanism is installed on the top of the top cover plate. A cylinder, a doffer, and a carding roller are rotatably connected between the inner walls of the carding frame. The doffer is disposed between the cylinder and the carding roller. A drive motor is installed on the outer wall of the carding frame, and the output shaft of the drive motor is connected to the rotating shaft of the cylinder via a belt. Although the carding device described above can remove residual yarn on the carding rollers during the carding process of viscose yarn, the residual yarn on the carding rollers will be transferred to the scraper roller. After the scraper roller has been working for a long time, there will be a lot of yarn adhering to it, which requires cleaning. However, the above device requires the entire structure, such as the top cover plate, to be disassembled for cleaning, making the whole process cumbersome and time-consuming, thus hindering the use of the device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a carding device for viscose yarn with a cleaning mechanism, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A carding device for viscose yarn with a cleaning mechanism includes a carding frame, inside which are arranged a cylinder, a doffer, and a carding roller, the doffer being positioned between the cylinder and the carding roller. A conveyor belt is arranged inside the carding frame, a moving component is arranged at the top of the carding frame, a moving plate is arranged at the top of the carding frame via the moving component, a hydraulic push rod is fixedly installed at the bottom of the moving plate, a moving frame is fixedly installed at the output end of the hydraulic push rod, an elastic component is arranged inside the moving frame, and a scraper roller is arranged inside the moving frame via the elastic component.

[0007] Preferably, the moving component includes a support plate disposed on the top of the carding frame, a frame fixedly installed on the top of the support plate, a drive motor fixedly installed on the front side of the frame, the output end of the drive motor extending through the frame into the frame and fixedly installed with a screw, the screw being threadedly connected to the moving plate, and the moving plate being slidably connected to the frame.

[0008] Preferably, the elastic component includes a fixed sleeve disposed on the top of the inner wall of the movable frame, a spring fixedly installed on the top of the inner wall of the fixed sleeve, a fixed post fixedly installed on the bottom end of the spring, the fixed post being slidably connected to the fixed sleeve, a movable frame fixedly installed on the bottom end of the fixed post, and the movable frame being rotatably connected to the scraper roller.

[0009] Preferably, a feed hopper is fixedly installed on the top of the carding frame, and a discharge port is provided through the left side of the carding frame.

[0010] Preferably, there are multiple support plates, and the multiple support plates are symmetrically distributed.

[0011] Preferably, there are multiple fixing sleeves, and the multiple fixing sleeves are distributed in an array.

[0012] Preferably, the frame has a rectangular frame structure and is made of stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This carding device for viscose yarn with a cleaning mechanism, during the carding process, cleans the carding roller by having the yarn filaments contact between the scraper needles on the scraper roller and the carding needles, thus hanging the yarn filaments on the scraper needles. When there are many yarn filaments on the scraper roller, a hydraulic push rod moves the moving frame, elastic component, and scraper roller upwards to a suitable height. Then, the moving component moves the moving plate back and forth, moving another scraper roller above the carding roller. Subsequently, a corresponding hydraulic push rod moves the corresponding moving frame, elastic component, and scraper roller downwards, bringing the moving frame into contact with the carding frame. At this point, the elastic component ensures that the scraper roller remains in contact with the carding roller, continuing to clean the remaining yarn filaments on the carding roller. Simultaneously, the yarn filaments on the previous scraper roller can be removed. This eliminates the need for prolonged machine downtime during the cleaning process, greatly improving cleaning efficiency, reducing time wasted on cleaning yarn filaments, and enabling the carding device to operate more quickly.

[0019] 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.

[0020] Reference Figure 1-4A carding device for viscose yarn with a cleaning mechanism includes a carding frame 1, a feed hopper 2 fixedly installed on the top of the carding frame 1, a discharge port 3 extending through the left side of the carding frame 1, a cylinder 4, a doffer 5, and a carding roller 6 arranged inside the carding frame 1, the doffer 5 being positioned between the cylinder 4 and the carding roller 6, a conveyor belt 7 arranged inside the carding frame 1, a moving component arranged on the top of the carding frame 1, and a moving plate 12 arranged on the top of the carding frame 1 via the moving component. The moving component includes a support plate 8 disposed on the top of the carding frame 1, and a frame 9 fixedly installed on the top of the support plate 8. The frame 9 has a rectangular frame structure and is made of stainless steel. To ensure the frame 9 has higher structural strength and thus greater durability, multiple support plates 8 are symmetrically distributed to provide more stable support for the frame 9. A drive motor 10 is fixedly installed on the front side of the frame 9. The output end of the drive motor 10 extends through the frame 9 into its interior and is fixedly mounted with a screw 11. The screw 11 is threadedly connected to a movable plate 12, which is slidably connected to the frame 9. This movable component facilitates the provision of driving force for the movement of the movable plate 12, thereby facilitating subsequent switching of the scraper roller 19. A liquid is fixedly installed at the bottom of the movable plate 12. A hydraulic push rod 13 is used, and a movable frame 14 is fixedly installed at the output end of the hydraulic push rod 13. An elastic component is installed inside the movable frame 14, and a scraper roller 19 is installed inside the movable frame 14 via the elastic component. This carding device for viscose yarn with a cleaning mechanism cleans the yarn during carding by having the yarn contact the scraper needles on the scraper roller 19 with the carding needles, thus cleaning the carding roller 6. When there is a large amount of yarn on the scraper roller 19, the hydraulic push rod 13 moves the movable frame 14, the elastic component, and the scraper roller 19 upwards to a suitable height. Then, the movable component moves the movable plate 12 back and forth, allowing... Another scraper roller 19 moves above the carding roller 6, and then the corresponding hydraulic push rod 13 causes the corresponding moving frame 14, elastic component, and scraper roller 19 to move downward, so that the moving frame 14 contacts the carding frame 1. At this time, the elastic component keeps the scraper roller 19 in contact with the carding roller 6, and the scraper roller 19 continues to clean the residual yarn on the carding roller 6. At the same time, the yarn on the previous scraper roller 19 can be removed. In this way, there is no need to stop the machine for a long time during the cleaning process, which greatly improves the cleaning efficiency, reduces the time wasted due to cleaning yarn, and enables the carding device to start production faster.

[0021] Specifically, the elastic component includes a fixed sleeve 15 disposed on the top of the inner wall of the movable frame 14. There are multiple fixed sleeves 15, which are arranged in an array. A spring 16 is fixedly installed on the top of the inner wall of the fixed sleeve 15. A fixed post 17 is fixedly installed at the bottom of the spring 16. The fixed post 17 is slidably connected to the fixed sleeve 15. A movable frame 18 is fixedly installed at the bottom of the fixed post 17. The movable frame 18 is rotatably connected to the scraper roller 19. During the downward movement of the elastic component and the scraper roller 19, the scraper roller 19 will first contact the carding roller 6. Then the scraper roller 19, the movable frame 18, and the fixed post 17 stop moving, and the fixed sleeve 15 continues to move downward, causing the spring 16 to be compressed. Subsequently, during the operation of the scraper roller 19, the scraper roller 19 can always be in contact with the carding roller 6, so that the scraper roller 19 can better clean the residual yarn on the carding roller 6.

[0022] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0023] In use: The viscose yarn raw material is poured into the feed hopper 2, and then falls between the cylinder 4 and the doffer 5. The viscose yarn raw material is combed and pressed into a web in the doffer 5 and the cylinder 4. Then, under the action of the combing roller 6, the viscose yarn is conveyed from the combing roller 6 and the doffer 5 to the conveyor belt 7. The conveyor belt 7 discharges the viscose yarn through the discharge port 3. At the same time, the yarn filaments come into contact with the combing needles on the scraper roller 19, and the yarn filaments are hung on the scraper needles, completing the cleaning of the combing roller 6. When there are a lot of yarn filaments on the scraper roller 19, the hydraulic push rod 13 moves the moving frame 14, the fixed sleeve 15, the spring 16, the fixed column 17, the movable frame 18, and the scraper roller 19 upward to a suitable height. Then, the screw 11 is rotated by the drive motor 10, causing the moving plate 12 to move back and forth, so that another scraper roller 19 moves to a suitable position above the carding roller 6. Then, the corresponding hydraulic push rod 13 causes the corresponding moving frame 14, fixed sleeve 15, spring 16, fixed column 17, movable frame 18, and scraper roller 19 to move downward, so that the moving frame 14 contacts the carding frame 1. At this time, the scraper roller 19 will generate force through the compression of the spring 16, so that the scraper roller 19 keeps in contact with the carding roller 6. Then, the scraper roller 19 continues to clean the residual yarn on the carding roller 6. At the same time, the yarn on the previous scraper roller 19 can be removed.
