Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of yarn tube cleaning mechanisms, in particular to a cleaning mechanism for treating residual yarns on the spindles of fine yarns in a spinning mill. Background Art
[0002] The spinning frame is one of the key equipment indispensable in modern textile production, mainly used for further processing roving into fine yarns for weaving and other purposes. Most of the current fine yarn tubes used are made of lightweight materials such as plastics or composite materials. The residual tail yarns on the yarn tubes usually need to be processed manually or by machines. However, some yarn tubes, as Figure 1 shown, are conical tubes and are provided with hook knife grooves and annular grooves. Currently, such yarn tubes can only be processed manually with a hook knife, which is inefficient and likely to damage the yarn tubes. In addition, such operations may also cut the fingers of the operators, increasing the safety risks during the production process. Therefore, a cleaning mechanism for treating residual yarns on the spindles of fine yarns in a spinning mill is proposed to solve the above problems. Content of the Utility Model
[0003] In view of this, the utility model provides a cleaning mechanism for treating residual yarns on the spindles of fine yarns in a spinning mill. This mechanism can efficiently and safely complete the cleaning operation of the residual yarns. Specifically, it includes a bidirectional moving cutting module, a fixture, and a groove finder. The bidirectional moving cutting module includes a forward pushing mechanism, a transverse moving mechanism, a cutting motor, and a cutter head. The transverse moving mechanism is installed on the forward pushing mechanism, and the cutting motor and the cutter head are installed on the transverse moving mechanism. The forward pushing mechanism and the transverse moving mechanism drive the cutting motor and the cutter head to cut the tail yarns of the yarn tube on the fixture. The groove finder includes a rubber wheel motor, a rubber wheel, and a groove card. The rubber wheel motor drives the rubber wheel to rotate, thereby driving the yarn tube to rotate. When the hook knife groove of the yarn tube rotates to a specific angle, the groove card catches the yarn tube to align another hook knife groove of the yarn tube with the cutter head of the bidirectional moving cutting module, facilitating the cutting process of the yarns in the hook knife groove of the yarn tube by the bidirectional moving cutting module.
[0004] For further description of the foregoing solution, the forward pushing mechanism uses a forward pushing cylinder and a first sliding table frame, and the transverse moving mechanism uses a transverse moving cylinder and a second sliding table frame. The transverse moving cylinder is installed on the first sliding table frame, and the cutting motor and the cutter head are installed on the second sliding table frame.
[0005] Further description of the foregoing solution: The fixture is installed on the support and is used to fix both ends of the yarn tube. An upper fixture for fixing the yarn tube is also installed above the fixture to fix the upper yarn tube. A cross beam is installed above the support, and an upper cutting module is installed below the cross beam. The upper cutting module is slidably installed on the slide rail of the slide cylinder. The upper cutting module performs the first cutting on the yarn tube fixed by the upper fixture to cut out the handle hook knife groove of the yarn tube, so that the groove finder can locate the hook knife groove. After the yarn tube is first cut by the upper cutting module, it falls into the lower fixture and is secondarily cut by the bidirectional moving cutting module.
[0006] Further, the upper fixture includes 4 cylinders, which are installed on the support in pairs facing each other. Clamping tube pieces are installed at the piston ends of the cylinders to facilitate fixing the yarn tube.
[0007] Further, a tube outlet hole is provided in the support near the end with the largest diameter of the yarn tube for discharging the processed yarn tube.
[0008] More preferably, air knives are provided on both the bidirectional moving cutting module and the upper cutting module, and the air knives blow the tail yarn on the yarn tube along the cutter head.
[0009] Compared with the prior art, the present utility model adopts a groove finder and a bidirectional moving cutting module. The groove finder can quickly find and fix the hook knife groove of the yarn tube. The bidirectional moving cutting module not only cuts the yarn in the hook knife groove, but also cuts the remaining yarn along the conical yarn tube wall, quickly and accurately locating and cutting the residual yarn on the yarn tube, significantly improving the efficiency of removing the tail yarn. Using automated equipment to replace manual operation reduces the chance of operators directly contacting sharp tools and lowers the risk of work-related injury accidents. In summary, the present utility model not only solves the problems of low efficiency, high operation risk, and yarn tube damage existing in the prior art, but also brings significant economic and social benefits to the enterprise.

[0025] To make the technical solutions and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.
[0026] The present utility model provides a cleaning mechanism for removing residual yarn on the spindles of spinning mills. The mechanism specifically includes a bidirectional moving cutting module 5, a fixture 3 and a groove finder 6. The bidirectional moving cutting module 5 includes a forward pushing mechanism 51, a transverse moving mechanism 52, a cutting motor 43 and a cutter head 42. The transverse moving mechanism 52 is installed on the forward pushing mechanism 51, and the cutting motor 43 and the cutter head 42 are installed on the transverse moving mechanism 52. The forward pushing mechanism 51 and the transverse moving mechanism 52 drive the cutting motor 43 and the cutter head 42 to cut the tail yarn of the yarn tube 7 on the fixture 3; the groove finder 6 includes a rubber wheel motor, a rubber wheel 62 and a card slot piece 63. The rubber wheel motor drives the rubber wheel 62 to rotate, thereby driving the yarn tube 7 to rotate. When the hook knife groove 71 of the yarn tube 7 rotates to a specific angle, the card slot piece 63 catches the yarn tube 7 to make another hook knife groove 71 of the yarn tube 7 opposite to the cutter head 42 of the bidirectional moving cutting module 5, facilitating the bidirectional moving cutting module 5 to cut the yarn in the hook knife groove 71 of the yarn tube 7.
[0027] As Figure 7 shown, the forward pushing mechanism 51 adopts a forward pushing cylinder 51 and a first sliding table frame 511, and the transverse moving mechanism 52 adopts a transverse moving cylinder 52 and a second sliding table frame 521; the transverse moving cylinder 52 is installed on the first sliding table frame 511, and the cutting motor 43 and the cutter head 42 are installed on the second sliding table frame 521.
[0028] As Figures 2 - 5 shown, the fixture 3 is installed on the support 1 and is used to fix both ends of the yarn tube 7. An upper fixture 2 for fixing the yarn tube 7 is also installed above the fixture 3 to fix the upper yarn tube 7. A cross beam 11 is installed above the support 1, and an upper cutting module 4 is installed below the cross beam 11. The upper cutting module 4 is slidably installed on the slide rail 41 of the slide cylinder. The upper cutting module 4 makes a first cut on the yarn tube 7 fixed by the upper fixture 2. After the yarn tube 7 is first cut by the upper cutting module 4, it falls into the lower fixture 3 and is secondarily cut by the bidirectional moving cutting module 5.
[0029] As Figure 5 shown, the upper fixture 2 includes four cylinders 21, which are installed on the support 1 in pairs and oppositely. The piston ends of the cylinders 21 are all installed with tube clamping pieces 31 to facilitate fixing the yarn tube 7. The support 1 near the end with the largest diameter of the yarn tube 7 is provided with a tube outlet hole for discharging the processed yarn tube 7. In some embodiments, the bidirectional moving cutting module 5 and the upper cutting module 4 are both provided with air knives, and the air knives blow the tail yarn on the yarn tube 7 along the cutter head 42 to facilitate cutting and prevent the yarn from winding around the cutter head 42.
[0030] In order to understand the disclosure of the present utility model more thoroughly and comprehensively, the principle will be further explained below in combination with the usage method.
[0031] During actual use, the present utility model is installed near the feeding device 8 of the yarn tube cleaning machine, as Figure 9 shown, and is docked with the feeding device 8. Its working process is as follows: The feeding device 8 places the yarn tubes 7 with the same direction at the upper fixture 2. As Figure 2 , 3 shown, the cylinders 21 of the upper fixture 2 clamp the yarn tube 7. Then, the cutter head 42 of the upper cutting module 4 above the yarn tube 7 starts to rotate to perform the first cutting on the yarn to expose the hook knife groove 71. And the slide table cylinder drives the motor 43 and the cutter head 42 to move on the slide rail 41.
[0032] After the yarn tube 7 is cut by the upper cutting module 4, it falls into the lower fixture 3 and is fixed. Then, as Figure 8 shown, the motor on the groove finder 6 drives the rubber wheel 62, and the rubber wheel 62 drives the yarn tube 7 to rotate. When the hook knife groove 71 of the yarn tube 7 is caught by the clamping groove piece 63, as Figure 6 shown, another hook knife groove 71 on the yarn tube 7 is facing the cutter head 42 of the bidirectional moving cutting module 5. At this time, the forward push cylinder 51 and the transverse moving cylinder 52 work, and the motor 43 drives the cutter head 42 to rotate to process the yarn in the hook knife groove 71. The forward push cylinder 51 also cooperates with the transverse moving cylinder 52 to drive the cutter head 42 to move along the wall of the yarn tube 7 to ensure that the yarn on the yarn tube 7 is completely cut. The yarn and the yarn tube 7 are automatically separated under their own weights and fall into the yarn channel and the yarn tube channel. On other devices, a tube pushing device 9 is also provided, as Figure 10 shown, and the processed yarn tube 7 is pushed out by the tube pushing device 9.
[0033] To sum up, the present utility model not only solves the problems of low efficiency, high operation risk, and yarn tube damage existing in the prior art, but also brings significant economic and social benefits to the enterprise.
