Description

Technical Field

[0001] The invention belongs to the technical field of textile doffing positioning, and in particular relates to a positioning mechanism for an automatic doffing device. Background Art

[0002] The doffing work of fine yarn is an important part of the production in the fine yarn workshop. It mainly involves winding the yarn onto a sleeve to remove impurities. There are two sets of dragon tendons, bobbin seats and bobbins, which are used alternately. When the yarn is full, the bobbin with the working dragon tendon is dropped and replaced by the empty bobbin with the spare dragon tendon. The positioning mechanism of the doffing machine is a fixed rod for placing and positioning the sleeve.

[0003] The positioning mechanism of the current doffing machine is to install multiple fixing rods on a fixing plate. The sleeve is placed on the fixing rod before winding, and then the winding is carried out. The fixing plate and the fixing rod are directly fixed by screws. If the force is too great when manually unloading the sleeve on the fixing rod, it is easy to cause the fixing rod to bend. The fixing rod is fixed by screws, and there are two rows of fixing rods. When the fixing rod located on the inside of the machine needs to be disassembled and replaced, the screws need to be turned to disassemble and replace it, which is inconvenient to operate.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-8As shown, the embodiment of the present invention provides a positioning mechanism for an automatic doffing device, including a fixed plate 1, two groups of doffing mechanisms 2 are provided on the fixed plate 1, and the doffing mechanism 2 includes a placement hole 203, and two groups of placement holes 203 are staggered on the surface of the fixed plate 1, and fixed seats 205 are placed on the two groups of placement holes 203, and multiple fixing seats 205 are fixed with connecting columns 204, and multiple connecting columns 204 are fixedly connected to a base 201, and multiple bases 201 are welded with fixing rods 202. Multiple fixing mechanisms 3 are equidistantly provided on both sides of the fixed plate 1, and the fixing mechanism 3 includes a fixing frame 301, and multiple fixing frames 301 are equidistantly fixedly connected on both sides of the fixed plate 1. Two groups of card slots 305 are relatively provided on the inner sides of the multiple fixing frames 301. The cam 308 is fixed on the cam 309 to prevent the cam from sliding onto the cam 309, and the cam 309 is fixed on the cam 309 to prevent the cam 308 from sliding onto the cam 309.When the thread is pulled out of the fixing rod 202, the thread is automatically wound around the threaded sleeve on the fixing rod 202. If the thread is pulled out with too much force, the fixing rod 202 will be deformed, resulting in the sleeve being unable to be fully sleeved with the fixing rod 202. At this time, the pressure column 303 on the card plate 302 is pressed to realize the sliding of the pressure column 303 toward the inside of the bottom cylinder 304, and the first spring 306 contracts. The two pressure plates 307 on the pressure column 303 simultaneously contact the interference blocks 308 on the two limit plates 309, and are inclined to the interference blocks 308. When the pressure plate 307 contacts the interference blocks 308, the two interference blocks 308 are moved relative to each other, and the two limit plates 309 move relative to each other, and finally the two limit plates 309 are moved from the fixing rod 202. When the locking plate 305 is unlocked, the locking plate 307 is unlocked and the locking plate 308 is unlocked, and the two locking plates 309 are unlocked and the two locking plates 309 are unlocked, so that the two locking plates 309 are unlocked and the two locking plates 309 are unlocked.

[0028] See also Figure 1-8 As shown, the cross section of the interference block 308 is a right-angled trapezoidal structure, and the interference block 308 is perpendicular to the limiting plate 309, in order to facilitate the stability of the pressing plate 307 when it contacts the interference block 308. The cross section of the pressure column 303 is an inverted "I"-shaped structure, and the pressure column 303 is perpendicular to the pressing plate 307, so that pressing the pressure column 303 simultaneously pushes the two limiting plates 309.

[0029] See also Figure 1-8 As shown, the diameter of the fixing seat 205 is equal to the diameter of the placement hole 203, and the diameter of the base 201 is larger than the diameter of the placement hole 203, making the fixing seat 205 more stable and non-shaky when placed. The fixing seat 205, the connecting column 204, and the base 201 form an "I"-shaped structure, and the sum of the heights of the connecting column 204 and the fixing seat 205 is equal to the height of the placement hole 203. This allows the base 201 to contact the fixing plate 1, facilitating the base 201 to cooperate with the clamping plate 302 to secure the fixing seat 205.

[0030] See also Figure 1-8 As shown, the pressure column 303 is provided with an oil filling mechanism 5, which includes an oil inlet 503. The oil inlet 503 is opened on multiple pressure columns 303, and the multiple pressure columns 303 are relatively opened with an oil channel 502 connected to the oil inlet 503. The oil channel 502 is arranged corresponding to the limit plate 309. Lubricating oil is dripped into the oil inlet 503, and the lubricating oil can be retained on the abutment block 308 to lubricate the limit plate 309 and the abutment block 308. The oil filling mechanism 5 also includes a guide groove 501. The guide groove 501 in the shape of an inverted "eight" is opened on the pressure plate 307 to facilitate the accurate dripping of lubricating oil onto the limit plate 309. The oil filling mechanism 5 further includes a filter 504 . The plurality of pressure columns 303 are each equipped with a filter 504 located at the oil inlet 503 to protect the oil inlet 503 and prevent debris from entering the oil passage 502 and causing blockage.

[0031] See also Figure 1-8 As shown, an anti-slip mechanism 4 is installed on the fixed rod 202, and the anti-slip mechanism 4 includes a rotating shaft 404, and multiple fixed rods 202 are fixed with rotating shafts 404, multiple rotating shafts 404 are rotatably connected with turntables 402, multiple turntables 402 are fixedly connected with protrusions 406, and multiple rotating shafts 404 and turntables 402 are clamped with torsion springs 405, and multiple fixed rods 202 are slidably connected with brake plates 403 that conflict with the textile sleeve rod, and the protrusions 406 and The brake plate 403 is in conflict, and the plurality of turntables 402 are rotatably connected with a pressure rod 401, and the pressure rod 401 passes through the outside of the fixed rod 202. When the sleeve is sleeved on the fixed rod 202, the bottom of the sleeve is in conflict with the pressure rod 401, thereby driving the pressure rod 401 to descend, and the turntable 402 rotates. Finally, the protrusion 406 pushes the brake plate 403 to the outside of the fixed rod 202, thereby achieving the braking of the sleeve to prevent the sleeve from rotating on the fixed rod 202 when winding.

[0032] In this embodiment, the pressure rod 401 is in an “L”-shaped structure, and the base 201 is provided with a groove at the bottom of the pressure rod 401 to facilitate the storage of the pressure rod 401 .

[0033] When the present invention is in use, first, when doffing, the fixing plate 1 is fixed to the doffing machine by bolts, and when doffing, the sleeve is sleeved on the fixing rod 202, and the yarn is automatically wound around the sleeve on the fixing rod 202. When unloading, if the fixing rod 202 is deformed due to excessive force, the sleeve cannot be fully sleeved with the fixing rod 202, and the pressure column 303 on the card plate 302 is pressed to realize the sliding of the pressure column 303 toward the inside of the bottom cylinder 304, and the first spring 306 contracts, and the two pressure plates 307 on the pressure column 303 simultaneously press the two limiting The retaining block 308 on the positioning plate 309 is in conflict with the retaining block 308, and is tilted to the retaining block 308. When the pressing plate 307 contacts the retaining block 308, the two retaining blocks 308 move relative to each other, and the two limiting plates 309 move relative to each other, and finally the two limiting plates 309 withdraw from the inside of the card slot 305 on the side wall of the fixed frame 301, and further pull the card plate 302 away from the direction of the fixed plate 1, and completely pull the card plate 302 out of the inside of the placement hole 203. At this time, the card plate 302 no longer limits the fixing seat 205, and the fixing rod 202 can be directly taken out, and the new fixing rod 202 can be replaced. When the locking cam 308 is unlocked, the locking cam 309 is unlocked, and the locking cam 309 is unlocked, so that the locking cam 309 is unlocked. When 07 is stuck, lubricating oil is injected into the oil inlet 503, and the lubricating oil flows from the oil channel 502 to the guide groove 501 on the pressure plate 307, and finally flows to the limit plate 309, lubricating the limit plate 309 and the resistance block 308. When the sleeve is mounted on the fixed rod 202, the bottom of the sleeve is in resistance with the pressure rod 401, and the pressure rod 401 drives the turntable 402 to rotate, and the protrusion 406 resists the brake plate 403 to the outside of the fixed rod 202, thereby squeezing the sleeve. The sleeve has a large friction force in the radial direction, which realizes the braking of the sleeve and avoids slipping during winding.
