Technical Field

[0001] This utility model belongs to the field of doffing assistance technology, specifically relating to an automatic doffing assistance device for a spinning machine. Background Technology

[0002] The spinning machine is an important piece of equipment in the textile process. It is mainly used to process semi-finished rovings or slivers through processes such as drafting, twisting, and winding to finally produce fine yarn tubes. Doffing is one of the spinning processes, which involves winding the yarn onto a tube for setting and removing impurities.

[0003] Chinese Patent Publication No. CN217677942U discloses an automatic doffing auxiliary device for a spinning machine, including a support plate. A motor is located at the center of the top of the support plate. The drive end of the motor extends to the bottom of the support plate and is equipped with a first gear. Four sets of second gears are connected to the bottom of the support plate and outside the first gear. Support rods are connected to the four outward bends at the bottom of the support plate. The four sets of second gears are connected to the support plate through connecting rods. An anti-detachment block is connected to the end of the connecting rod away from the support plate. A limiting member is sleeved below the anti-detachment block and outside the support rod. A fixing block is connected between two sets of limiting members. A groove is opened at the end of the limiting member away from the support rod. Compared with existing doffing machines, this utility model can improve the overall convenience, controllability, and practicality of the doffing machine through its design.

[0004] While the automatic doffing auxiliary device for spinning machines mentioned above can improve the overall convenience, controllability, and practicality of the doffing machine, the device lacks a limiting structure for the spindles during the doffing process. As a result, the yarn setting effect is easily affected by the detachment or instability of the spindles during doffing. Therefore, we propose an automatic doffing auxiliary device for spinning machines. Utility Model Content

[0005] To address the problem mentioned in the background art where the device lacks a limiting structure for the yarn spindle during the doffing process, resulting in the yarn setting effect being affected by the spindle detachment or instability, this utility model provides an automatic doffing auxiliary device for a spinning frame.

[0007] A positioning block is installed above the linkage turntable. Electric push rods are fixedly connected to both sides of the lower part of the positioning block through the output end. A lifting plate is sleeved on the outside of the positioning block, and a push plate is fixedly installed on the outside of the lifting plate.

[0008] In a preferred embodiment of the automatic doffing auxiliary device for a spinning machine according to this utility model, the electric push rod and the positioning block form a telescopic structure, and the positioning block is slidably connected to the linkage turntable.

[0010] In a preferred embodiment of the automatic doffing auxiliary device for a spinning machine according to this utility model, the winding motor and the drive gear form a rotating structure, and the drive gear is meshed with the driven gear.

[0011] As a preferred embodiment of the automatic doffing auxiliary device for a spinning machine according to this utility model, a telescopic rod is slidably installed on one side of the lifting plate, and a connecting rod is installed on the other side of the lifting plate. One end of the connecting rod is fixed with a connecting end, and a telescopic push rod is fixedly installed on one side above both the connecting rod and the telescopic rod.

[0012] In a preferred embodiment of the automatic doffing auxiliary device for a spinning machine according to this utility model, the telescopic push rod forms a telescopic structure with the connecting rod and the telescopic rod respectively, and the connecting rod engages with the telescopic push rod through the connecting end.

[0013] As a preferred embodiment of the automatic doffing auxiliary device for a spinning machine according to this utility model, a lifting push rod is connected below the push plate, and the lifting push rod forms a telescopic structure between the push plate and the lifting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this application, the electric push rod can drive the positioning block to move horizontally relative to each other, thereby adjusting the relative position of the positioning block according to the outer ring size of the yarn spindle. This makes it easier to support the yarn spindle from the inside and limit its movement, preventing the problem that the device lacks a limiting structure for the yarn spindle during the doffing process, which could easily lead to the yarn setting effect being affected by the detachment or instability of the yarn spindle.

[0024] Example 1

[0025] like Figures 1-6 As shown;

[0026] An automatic doffing auxiliary device for a spinning machine includes a worktable 1, a take-up motor 2 installed at the bottom of the worktable 1, a drive gear 3 fixed at the drive end of the take-up motor 2, driven gears 4 on both sides of the drive gear 3, and a linkage turntable 5 fixedly connected above the driven gears 4 and the drive gear 3.

[0027] A positioning block 6 is installed above the linkage turntable 5. Electric push rods 7 are fixedly connected to both sides below the positioning block 6 through the output end. A lifting plate 8 is sleeved on the outside of the positioning block 6. A push plate 10 is fixedly installed on the outside of the lifting plate 8.

[0028] In this implementation scheme: the electric push rod 7 can drive the positioning block 6 to move horizontally relative to each other, thereby adjusting the relative position of the positioning block 6 according to the outer ring size of the spindle, so that the positioning block 6 can support the spindle from the inside and limit its movement.

[0029] Furthermore:

[0030] In an optional embodiment, the electric push rod 7 and the positioning block 6 form a telescopic structure, and the positioning block 6 is slidably connected to the linkage turntable 5.

[0031] In this implementation scheme: the electric push rod 7 can drive the positioning block 6 to move horizontally relative to each other, thereby adjusting the relative position of the positioning block 6 according to the outer ring size of the spindle, so as to support the spindle from the inside and limit its movement through the positioning block 6.

[0032] Furthermore:

[0033] In an optional embodiment, the lifting plate 8 has an inner ring hole 15 inside, and the positioning block 6 passes through the inner ring hole 15 inside the lifting plate 8.

[0034] In this implementation plan: the lifting plate 8 can support the installed spindle.

[0035] Furthermore:

[0036] In an optional embodiment, the winding motor 2 and the drive gear 3 form a rotating structure, and the drive gear 3 is meshed with the driven gear 4.

[0037] In this implementation scheme: the winding motor 2 can drive the drive gear 3 to rotate, and the rotating drive gear 3 can drive the driven gear 4 to rotate synchronously, thereby driving the three linkage turntables 5, the positioning block 6 and the yarn spindle to rotate synchronously, which facilitates the winding and shaping of the yarn.

[0038] Furthermore:

[0039] In an optional embodiment, a telescopic rod 11 is slidably installed on one side of the lifting plate 8, and a docking rod 12 is installed on the other side of the lifting plate 8. One end of the docking rod 12 is fixed with a docking end 14. A telescopic push rod 13 is fixedly installed on one side above both the docking rod 12 and the telescopic rod 11. The telescopic push rod 13 forms a telescopic structure with the docking rod 12 and the telescopic rod 11 respectively. The docking rod 12 is engaged with the telescopic push rod 13 through the docking end 14.

[0040] In this embodiment, the telescopic push rod 13 can horizontally transmit the docking rod 12 and the telescopic rod 11 respectively, thereby enabling the docking end 14 of the docking rod 12 to dock and engage with the telescopic push rod 13.

[0041] Furthermore:

[0042] In an optional embodiment, a lifting push rod 9 is connected below the push plate 10, and the lifting push rod 9 forms a telescopic structure between the push plate 10 and the lifting plate 8.

[0043] In this implementation scheme: the lifting push rod 9 can drive the push plate 10 and the lifting plate 8 to move vertically, thereby sending the yarn spindle upwards, making it easier to remove the yarn spindle.

[0044] Working principle: First, the yarn spindles are fitted onto the positioning blocks 6 one by one. Then, the electric push rod 7 is activated, which drives the positioning blocks 6 to move horizontally relative to each other. This allows the relative position of the positioning blocks 6 to be adjusted according to the outer size of the yarn spindles, facilitating the internal support and limiting of the yarn spindles. Next, the take-up motor 2 is activated, which drives the drive gear 3 to rotate. The rotating drive gear 3 drives the driven gear 4 to rotate synchronously, thereby driving the three linked turntables 5, the positioning blocks 6, and the yarn spindles to rotate synchronously. This facilitates the winding and shaping of the yarn; after winding, the linkage turntable 5 is adjusted to the starting position, and the telescopic push rod 13 is activated. The telescopic push rod 13 horizontally conveys the docking rod 12 and the telescopic rod 11 respectively, so that the docking end 14 of the docking rod 12 and the telescopic push rod 13 can be docked and engaged with each other; finally, the two lifting push rods 9 are activated at the same time. The lifting push rods 9 are products of the same brand and size. The lifting push rods 9 drive the push plate 10 and the lifting plate 8 to move vertically at the same time, so that the yarn spindle can be sent upward, making it easy to remove the yarn spindle.
