Description

Technical Field

[0001] This utility model relates to the field of textile auxiliary equipment, and in particular to a cleaning mechanism for a twisting machine. Background Technology

[0002] A doubling machine is a commonly used textile processing device, mainly used to twist yarns to improve their strength and uniformity. During yarn operation, due to friction, static electricity, and other factors, lint, dust, or other particulate impurities easily adhere to the yarn surface. If these impurities are not removed in time, they will not only affect the yarn quality but may also cause wear or blockage of equipment parts. Therefore, a cleaning mechanism has become an indispensable component of a doubling machine. A cleaning device for a doubling twister, with existing patent publication number CN221956257U, includes a horizontally positioned support base, a vertically positioned support column, a horizontally positioned cleaning cylinder rotatably connected to the support column, a soft brush fixed circumferentially inside the cleaning cylinder, a guide bracket fixed to the end of the support column near the output port of the doubling twister, and a guide wheel rotatably connected to the guide bracket; a gear ring is fixed to the outer wall of the end of the cleaning cylinder away from the doubling twister, and the gear ring is connected to a motor through a gear transmission mechanism. The purpose of this patent is to solve the problem that existing twisting machines cannot clean the twisted yarn. The existing cleaning mechanisms for doubling machines include fixed cleaning boxes or openings through which the yarn must pass to achieve the cleaning function. However, when the yarn breaks or needs to be replaced, the operator must manually thread the yarn out or in through the cleaning box, which is cumbersome and inefficient, especially in multi-spindle production environments, significantly impacting overall production efficiency. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a cleaning mechanism for a twisting machine to solve the technical problems in the prior art.

[0004] Based on the above objectives, this utility model provides a cleaning mechanism for a twisting machine, including a housing, a guide wheel, and a guide rod, and further including: a guide plate fixed to the housing, which has a guide hole, wherein the guide hole, the guide wheel, and the guide rod are arranged sequentially along the yarn conveying direction; The lower cleaning box is fixed to the guide plate and is located between the guide wheel and the guide rod; The upper cleaning box is located on top of the lower cleaning box; Cleaning nozzles are fixed to the inner walls of the upper and lower cleaning boxes respectively, and the two together form a tapered opening for the yarn to pass through, which gradually narrows in the opposite direction of yarn feeding. A fixed cylinder is fixed to the guide plate and located on one side of the upper cleaning box. A rotating tube is rotatably installed inside the fixed cylinder through a bearing. The upper and lower ends of the rotating tube pass through the fixed cylinder. An arc-shaped guide groove is opened on the side wall of the rotating tube, which passes through the tube wall. The lifting rod is movably inserted into the rotating tube, with its top fixed to the upper cleaning box, and its side wall fixed with a sliding pin that slides along the inner wall of the fixed cylinder via an arc-shaped guide groove.

[0005] Preferably, the side wall of the fixed cylinder is provided with a vertical groove, and the end of the sliding pin is slidably installed in the groove.

[0006] Preferably, the mechanism further includes: an upper locking member sleeved on the lower end of the rotating tube, the top of the upper locking member being fixed to the bottom of the guide plate; A lower locking member is inserted and fitted with the bottom surface of the upper locking member, and the lower locking member is slidably fitted onto the lower end of the rotating tube; A base plate fixed to the bottom end of the rotating tube and a spring sleeved on the lower end of the rotating tube, one end of the spring being fixed to the bottom of the lower locking member and the other end being fixed to the surface of the base plate.

[0007] Preferably, the bottom surface of the upper locking member and the top surface of the lower locking member are provided with multiple teeth at equal intervals along the circumferential direction, and the teeth on the bottom surface of the upper locking member and the teeth on the top surface of the lower locking member are staggered.

[0008] Preferably, keyways are provided on both sides of the lower end surface of the rotating tube, and a sliding key that slides in cooperation with the keyway is fixed on the inner ring of the lower locking member.

[0009] Preferably, the sidewall of the lower locking member is provided with multiple grooves at equal intervals along the circumference.

[0010] Preferably, the mechanism further includes a dust collection box fixed to the guide plate; An exhaust fan fixed to one side of the dust collection box; A filter screen that can be detachably installed inside the dust collection box; A suction pipe is fixed to the other side of the dust collection box, and one end of the suction pipe is connected to the interior of the lower cleaning box.

[0011] Preferably, the top of the dust collection box has an installation groove, through which the filter screen is movably inserted into the dust collection box, and a sealing element is provided between the side wall of the installation groove and the filter screen.

[0012] The beneficial effects of this utility model are as follows: The cleaning mechanism of this utility model for a twisting machine, through the linkage mechanism between the rotating tube and the lifting rod that can be operated with one hand, allows the upper cleaning box to rise vertically during yarn changeover by simply rotating the lower locking component, enabling rapid separation of the upper and lower cleaning boxes without the need for manual yarn threading, greatly simplifying the operation process. It is particularly suitable for multi-spindle production scenarios, significantly shortening yarn changeover time and improving overall production efficiency. By employing a toothed locking structure with upper and lower locking parts, combined with a spring return function, reliable self-locking can be achieved at any lifting position, ensuring the upper cleaning box remains stable in the open state and preventing accidental closure from interfering with yarn changing operations. Furthermore, the conical cleaning nozzle design effectively removes lint and particulate impurities from the yarn surface, and combined with the exhaust fan, dust collection box, and removable filter, a negative pressure dust collection system is formed to collect contaminants in real time, preventing secondary adhesion.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0017] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0018] The first aspect of this utility model provides a cleaning mechanism for a doubling twister, such as... Figure 1-5 As shown, it includes a housing 1, a guide wheel 2 and a guide rod 3, and also includes a guide plate fixed to the housing 1, which has a guide hole. The guide hole, the guide wheel 2 and the guide rod 3 are arranged sequentially along the yarn conveying direction. The lower cleaning box 4 is fixed to the guide plate and is located between the guide wheel 2 and the guide rod 3; The upper cleaning box 5 is located at the top of the lower cleaning box 4; Cleaning nozzles 6 are fixed to the inner walls of the upper cleaning box 5 and the lower cleaning box 4 respectively. The two together form a tapered opening for the yarn to pass through, and the opening gradually narrows in the opposite direction of the yarn feeding. A fixed cylinder 7 is fixed to the guide plate and located on one side of the upper cleaning box 5. A rotating tube 8 is rotatably installed inside the fixed cylinder 7 through a bearing. The upper and lower ends of the rotating tube 8 pass through the fixed cylinder 7. An arc-shaped guide groove 801 that passes through the tube wall is opened on the side wall of the rotating tube 8. The lifting rod 9 is movably inserted into the rotating tube 8, with its top fixed to the upper cleaning box 5, and its side wall fixed with a sliding pin 901 that slides on the inner wall of the fixed cylinder 7 via an arc-shaped guide groove 801.

[0019] When changing yarn on a twisting machine, the user rotates the rotating tube 8 with one hand, causing the lifting rod 9, which moves inside the rotating tube 8, to move vertically upward along the arc-shaped guide groove 801 under the sliding engagement of the sliding pin 901 and the inner wall of the fixed cylinder 7. This causes the lifting rod 9 to move the upper cleaning box 5 upward, thus separating the upper cleaning box 5 from the lower cleaning box 4, which facilitates yarn changing. This avoids the problem of low yarn changing efficiency caused by the operator having to manually thread the yarn out or in during the existing yarn changing operation.

[0020] In this embodiment: the side wall of the fixed cylinder 7 is provided with a vertical groove 701, and the end of the sliding pin 901 is slidably installed in the groove 701.

[0021] As the rotating tube 8 rotates, the rotating tube 8 drives the lifting rod 9 to rotate through the arc-shaped guide groove 801 on the side wall. However, since the lifting rod 9 is slidably installed in the slide groove 701 through the sliding pin 901, when the rotating tube 8 rotates, the lifting rod 9 pushes the sliding pin 901 to slide vertically upward along the slide groove 701 as the rotating tube 8 rotates, thereby realizing the vertical lifting of the lifting rod 9.

[0022] In this embodiment, the mechanism further includes an upper locking member 10 sleeved on the lower end of the rotating tube 8, with the top of the upper locking member 10 fixed to the bottom of the guide plate. The lower locking member 11 is inserted and fitted with the bottom surface of the upper locking member 10, and the lower locking member 11 is slidably fitted onto the lower end of the rotating tube 8; The base plate 12 is fixed to the bottom end of the rotating tube 8 and the spring 13 is sleeved on the lower end of the rotating tube 8. One end of the spring 13 is fixed to the bottom of the lower locking member 11 and the other end is fixed to the surface of the base plate 12.

[0023] When changing yarn on the twisting machine, pulling down the lower locking member 11 releases its top surface from engagement with the bottom surface of the upper locking member 10. The lower locking member 11 can then be rotated, causing the rotating tube 8 to rotate. As the rotating tube 8 rotates and the lifting rod 9 reaches its vertical position, the lower locking member 11 is released. The spring 13 then elastically returns the lower locking member 11 to its original position, causing it to re-engage with the upper locking member 10 and lock itself in place. This locks the height of the lifting rod 9. This method facilitates one-handed operation and allows for easy separation of the lower cleaning box 4 and upper cleaning box 5, eliminating the need for manual yarn threading and greatly simplifying the operation. It is particularly suitable for multi-spindle production scenarios, significantly reducing yarn changeover time and improving overall production efficiency.

[0024] In this embodiment, the bottom surface of the upper locking member 10 and the top surface of the lower locking member 11 are both provided with multiple teeth at equal intervals along the circumferential direction, and the teeth on the bottom surface of the upper locking member 10 and the teeth on the top surface of the lower locking member 11 are arranged alternately.

[0025] When the lower locking member 11 is not rotated, the teeth on the top surface of the lower locking member 11 are re-inserted into the teeth on the bottom surface of the upper locking member 10 under the elastic reset of the spring 13, locking the rotation of the lower locking member 11, ensuring that the upper cleaning box 5 remains stable in the open state, realizing the self-locking function, and further realizing the adjustment of the lifting rod 9 to any height.

[0026] In this embodiment, keyways are provided on both sides of the lower end surface of the rotating tube 8, and a sliding key that slides in conjunction with the keyway is fixed to the inner ring of the lower locking member 11. It should be noted that the lower locking member 11 is slidably installed in the keyway on the surface of the rotating tube 8 via the sliding key, and can drive the rotating tube 8 to rotate when the lower locking member 11 is rotated.

[0027] In this embodiment, the sidewall of the lower locking member 11 is provided with multiple grooves at equal intervals along the circumference. By providing grooves, the friction between the user's hand and the lower locking member 11 is increased when the user rotates the lower locking member 11, facilitating the rotation of the lower locking member 11.

[0028] In this embodiment, the mechanism further includes a dust collection box 14 fixed to the guide plate; A fan 15 is fixed to one side of the dust collection box 14; A filter screen 16 is detachably installed inside the dust collection box 14; A suction pipe 17 is fixed to the other side of the dust collection box 14, and one end of the suction pipe 17 is connected to the interior of the lower cleaning box 4.

[0029] After the cleaning nozzles 6 on one side of the lower cleaning box 4 and the upper cleaning box 5 scrape off the lint and attached particles on the surface of the yarn, the lint and attached particles are drawn in by the exhaust fan 15 and enter the dust collection box 14 through the dust suction pipe 17 for collection. The collected lint and attached particles are blocked by the filter screen 16.

[0030] In this embodiment, a mounting groove is provided on the top of the dust collection box 14. The filter screen 16 is movably inserted into the dust collection box 14 through this mounting groove, and a sealing element is provided between the side wall of the mounting groove and the filter screen 16. It should be noted that the sealing element between the side wall of the mounting groove and the filter screen 16 improves the sealing performance inside the dust collection box 14. Furthermore, the detachable installation of the filter screen 16 facilitates cleaning of the filter pores on its surface and prevents clogging of the pores.
