Description

Technical Field

[0001] This invention relates to the field of spinning machine technology, specifically an automatic vertical spindle spinning machine. Background Technology

[0002] A spinning machine is a machine that takes semi-finished roving and winds it into fine yarn during the spinning process. Spinning machines can be divided into spinning machines with moving spindles and spinning machines with moving frames according to their working principle. In a spinning machine with moving frames, the spindle end is stationary while the roving end moves back and forth to stretch the roving and at the same time twists and winds it into fine yarn.

[0003] In order to ensure processing efficiency, existing spinning machines spin multiple sets of yarn simultaneously during the spinning process. The spinning process of existing spinning machines has a high degree of automation and can basically complete the spinning process automatically. However, after the spinning process is completed, the wound yarn needs to be removed from the spindle and replaced with a new roll for rewinding. In addition, one end of the spun yarn needs to be fixed on the new roll for rewinding. The manual roll changing method is inefficient and greatly affects the spinning efficiency.

[0004] Based on this, the present invention designs an automatic vertical spindle spinning machine to solve the problem that the need to manually change the spool during the spinning process affects the processing efficiency. Summary of the Invention

[0008] As a further embodiment of the present invention, the adjusting assembly includes a second fixing plate, which is slidably disposed on a threaded rod and rotatably disposed inside a support base. Top blocks are fixedly connected to both sides of the top of the second fixing plate. A first fixing plate is slidably connected to the threaded rod, and a pad for limiting the downward movement of the first fixing plate is fixedly connected to the top of the threaded rod. Clamping blocks that engage with the bottom of the drum are slidably connected to both sides of the first fixing plate. A connecting spring for resetting the clamping blocks is fixedly connected to the first fixing plate. A docking block is fixedly connected to the top of the threaded rod. Several equidistant rotating blocks are disposed inside the docking block, and a torsion spring for resetting the rotating blocks is disposed on the rotating blocks. A slot for docking with the rotating blocks is formed on the top of the first fixing plate.

[0009] As a further embodiment of the present invention, a lever is rotatably mounted on the track frame, and the bottom of the threaded rod passes through the track frame and is mounted at the bottom of the support base.

[0010] As a further embodiment of the present invention, a fixed frame is provided on one side of the support base, a transmission frame is fixedly connected to the fixed frame, a first rotating shaft is provided on the transmission frame, a first connecting rod is fixedly connected to the first rotating shaft, the lifting rod is fixedly provided at one end of the first connecting rod, a second rotating shaft is provided on the transmission frame, a second connecting rod is fixedly connected to the second rotating shaft, one end of the pressing rod and the second connecting rod are fixedly connected, a first motor is fixedly connected to the fixed frame, and the output shaft of the first motor is fixedly connected to the transmission frame.

[0017] This invention employs an automatic roll-changing mechanism. During the spinning process, once a sufficient amount of yarn has been wound onto the roll, the rolled roll is removed and replaced with a new roll without affecting the spinning machine's continued spinning. During roll replacement, the wound yarn can be wound onto the outward-extending sliding plate, and the rollers compress the yarn to wrap around the sliding plate. After the roll replacement is completed, the new roll can compress the sliding plate, causing the wound yarn to be reattached onto the roll. The roll then works with the rollers to wind and wind the yarn, effectively improving the processing efficiency during spinning. Attached Figure Description

[0028] Please see Figure 1-8 The present invention provides a technical solution: an automatic vertical spindle spinning machine, including a slide rail 4, a slide block 3 slidably connected on the slide rail 4, a roving roll 1 rotatably mounted on the top of the slide block 3, a yarn guide roller 2 rotatably connected inside the slide block 3, a support base 14 on one side of the slide rail 4, a plurality of equally spaced track frames 21 fixedly connected to the top of the support base 14, a lifting rod 5 on one side of the support base 14, a pressing rod 13 at the bottom of the lifting rod 5, and an automatic roll changing mechanism on the support base 14. The automatic roll changing mechanism is used to spin the roving into fine yarn and can change the roll after winding up to a certain extent.

[0029] When the above scheme is put into practical use, the roving roll 1 to be spun is placed on the upper end of the slide block 3. The end thread on the roving roll 1 is taken out and passed through the thread guide roller 2. It is pulled out from the top of the lifting rod 5 and the bottom of the pressing rod 13 and wound onto the automatic winding mechanism. The coarse yarn on the roving roll 1 is finally spun into fine yarn and wound onto the automatic winding mechanism after several steps of stretching, twisting and winding. After a certain amount of fine yarn is wound, the automatic winding mechanism can automatically change the roll, thereby improving the spinning efficiency.

[0030] As a further embodiment of the present invention, the automatic roll changing mechanism includes a threaded rod 29, which is slidably disposed inside the support base 14. A transmission gear 18 is fixedly connected to the bottom of the threaded rod 29. A second motor 19 is fixedly connected to the bottom of the support base 14. A fixed gear 17 that meshes with the transmission gear 18 is fixedly connected to the output shaft of the second motor 19. A limit shaft 20 is fixedly connected to the bottom of the support base 14. A limit groove that slidably connects to the limit shaft 20 is provided on one side of the threaded rod 29. A connecting plate 15 is fixedly connected to the top of the support base 14. A twisting rod 35 is rotatably connected to the top of the connecting plate 15. The bottom of the twisting rod 35 is fixedly connected to... A fixed column 24 is provided, on which a plurality of equally spaced sliding grooves 26 are provided. Connecting pieces 22 are slidably connected to the upper and lower sides of each sliding groove 26. Two connecting pieces 22 rotate together to form a sliding piece 23. A first spring 25 is fixedly connected inside the sliding groove 26 to push the sliding piece 23 outward from the sliding groove 26. A sliding plate 37 is slidably connected to the connecting plate 15. A roller 39 is rotatably connected to the sliding plate 37. A second spring 38 is fixedly connected to the sliding plate 37 for its reset. An adjustment component is provided on the threaded rod 29. The adjustment component is used to switch the clamping and releasing state of the drum, thereby realizing the replacement of the drum.

[0031] The adjustment assembly includes a second fixing plate 30, which is slidably disposed on the threaded rod 29 and rotatably disposed inside the support base 14. Top blocks 31 are fixedly connected to both sides of the top of the second fixing plate 30. A first fixing plate 28 is slidably connected to the threaded rod 29. A pad for limiting the downward movement of the first fixing plate 28 is fixedly connected to the top of the threaded rod 29. Clamping blocks 27 that engage with the bottom of the drum are slidably connected to both sides of the first fixing plate 28. A connecting spring for resetting the clamping blocks 27 is fixedly connected to the first fixing plate 28. A docking block 33 is fixedly connected to the top of the threaded rod 29. Several rotating blocks 32 are equidistantly distributed inside the docking block 33. Torsion springs for resetting the rotating blocks 32 are provided on the rotating blocks 32. A slot 34 for engaging with the rotating blocks 32 is opened on the top of the first fixing plate 28. A lever 36 is rotatably disposed on the track frame 21. The bottom of the threaded rod 29 passes through the track frame 21 and is disposed at the bottom of the support base 14.

[0032] When the above solution is put into practical use, such as Figure 2-8As shown, when the drum needs to be replaced, the second motor 19 drives the fixed gear 17 to rotate, which in turn drives the transmission gear 18 to rotate. The rotation of the transmission gear 18 allows the threaded rod 29 to slide vertically inside the support base 14 under the limiting action of the limiting shaft 20. The drum, together with the first fixing plate 28, will slide down with the threaded rod 29 under the action of gravity until the drum is completely detached from the fixing post 24. At this time, the top of the docking block 33 is still docked with the bottom of the fixing post 24, while the sliding plate 23 on the fixing post 24 will be squeezed outward under the elastic force of the first spring 25, that is, the connecting plate 22 will... As the sliding plate 23 rotates, it shifts outward from the groove 26. At this point, the connecting block 33 continues to rotate the fixing column 24 to wind up the yarn. The wound yarn can directly wrap around the outside of the sliding plate 23. After the yarn has wound a certain number of turns, manually cut the connection between the yarn on the drum and the sliding plate 23. Then, continue rotating the threaded rod 29 to make the first fixing plate 28 slide down. The threaded rod 29 continues to slide down until the rotating block 32 on the connecting block 33, which rotates outward under the action of the torsion spring, contacts the inner wall of the groove 34, causing the first fixing plate 28 to press down until the clamping block 27 contacts the top block 31 and, along with the squeezing... The clamping block 27 is pushed outward. To ensure that the clamping block 27 can fully contact the top block 31, the top block 31 can be semi-circular. After the clamping block 27 is pushed outward, it disengages from the drum. At this time, the lever 36 is activated, which moves the drum of the wound yarn on the first fixing plate 28 to slide along the track frame 21, and moves the unwound drum on the other side of the track frame 21 to the top of the first fixing plate 28. Then, the second motor 19 rotates in the opposite direction, driving the threaded rod 29 to rise through the transmission. When the clamping block 27 disengages from the top block 31, the spring force of the return spring on the clamping block 27 pushes the clamping block 27 back to its original position. Holding the drum, the first fixing plate 28 is pushed up by the washer on the threaded rod 29. During the upward process, the top of the drum will first contact the inclined connecting plate 22. As the threaded rod 29 rises, the drum will push the connecting plate 22 to rotate and reset. The sliding plate 23 will be gradually compressed and the first spring 25 will return to the inside of the slide groove 26. The yarn wound on the sliding plate 23 will fall back onto the drum. The roller 39 pushed by the second spring 38 will contact the side wall of the drum, fixing the yarn on the drum and preventing the yarn from rotating relative to the drum when it rotates, until the threaded rod 29 reconnects with the fixing post 24.

[0033] As a further embodiment of the present invention, a fixed frame 6 is provided on one side of the support base 14, a transmission frame 8 is fixedly connected to the fixed frame 6, a first rotating shaft 9 is provided on the transmission frame 8, a first connecting rod 10 is fixedly connected to the first rotating shaft 9, the lifting rod 5 is fixedly provided at one end of the first connecting rod 10, a second rotating shaft 11 is provided on the transmission frame 8, a second connecting rod 12 is fixedly connected to the second rotating shaft 11, one end of the pressing rod 13 and the second connecting rod 12 are fixedly connected, a first motor 7 is fixedly connected to the fixed frame 6, the output shaft of the first motor 7 is fixedly connected to the transmission frame 8, and the first connecting rod 10 can drive the lifting rod 5 to move above the twisting rod 35;

[0034] When the above solution is put into practical use, such as Figure 2 As shown, when twisting the roving, the first motor 7 is started to drive the first shaft 9 to rotate, causing the first connecting rod 10 to rotate until the lifting rod 5 is at the top of the twisting rod 35. At this time, the roving passing through the lifting rod 5 will be lifted, and then the threaded rod 29 will drive the twisting rod 35 to rotate faster. Since one end of the roving is higher than the twisting rod 35, the roving cannot be wrapped around the twisting rod 35 when the twisting rod 35 rotates, but rotates with the twisting rod 35, that is, the twisting action of the roving is performed, twisting it into fine yarn. After the twisting action is completed, some fine yarn will be wrapped around the twisting rod 35. At this time, the second motor 19 rotates in the opposite direction to retract some of the fine yarn, so that... Once the yarn wound on the twisting rod 35 is completely detached, the first motor 7 rotates in the opposite direction, the first connecting rod 10 drives the lifting rod 5 to descend to a certain height, and the second connecting rod 12 drives the pressing rod 13 to descend to the same level as the drum. This allows the twisted yarn to be wound onto the drum as the threaded rod 29 rotates. During the winding process, the slide block 3 slides on the slide rail 4, and the roving roll 1 does not rotate. This ensures that only the twisted yarn is wound up. After winding, the slide block 3 slides in the opposite direction on the slide rail 4, while the roving roll 1 rotates to stretch the roving. The above actions are repeated to complete the twisting, traction, and winding actions to finish spinning.

[0035] As a further embodiment of the present invention, the bottom of the fixing post 24 is provided with a slot for engaging with the docking block 33, and the docking block 33 can be completely fitted with the bottom inner wall of the fixing post 24.

[0036] When the above solution is put into actual use, the two parts fit together perfectly, so that the docking block 33 can accurately drive the fixed column 24 to rotate together when it rotates, thus avoiding the problem of relative rotation.

[0037] As a further embodiment of the present invention, a hinge 16 is connected to the transmission gears 18 at the bottom of several threaded rods 29.

[0038] When the above scheme is put into practical use, the hinge 16 enables multiple sets of threaded rods 29 to rotate synchronously through the transmission gear 18 for spinning.

[0039] As a further embodiment of the present invention, the top of the docking block 33 is provided with a cone-shaped block for docking with the slot;

[0040] When the above solution is put into practical use, the conical block enables the threaded rod 29 to be more accurately inserted into the fixed post 24 when it rises and connects with the fixed post 24.

[0041] As a further embodiment of the present invention, the outer walls of the twisting rod 35 are all smooth walls;

[0042] When the above solution is put into practical use, the smooth twisting rod 35 can avoid causing significant wear to the yarn during twisting rotation.

[0043] Working principle: When twisting the roving, the first motor 7 is started, driving the first rotating shaft 9 to rotate, causing the first connecting rod 10 to rotate until the lifting rod 5 is at the top of the twisting rod 35. At this time, the roving passing through the lifting rod 5 will be lifted, and then the threaded rod 29 will drive the twisting rod 35 to rotate faster. Since one end of the roving is higher than the twisting rod 35, the roving cannot be wrapped around the twisting rod 35 when it rotates, but rotates with the twisting rod 35, that is, the twisting action of the roving is performed, twisting it into fine yarn. After the twisting action is completed, some fine yarn will be wrapped around the twisting rod 35. At this time, the second motor 19 rotates in the opposite direction to retract some of the fine yarn. This causes the yarn wound on the twisting rod 35 to completely detach. Then, the first motor 7 rotates in the opposite direction, and the first connecting rod 10 drives the lifting rod 5 to descend to a certain height. The second connecting rod 12 drives the pressing rod 13 to descend to the same level as the drum. This allows the twisted yarn to be wound onto the drum as the threaded rod 29 rotates. During the winding process, the slide block 3 slides on the slide rail 4, and the roving roll 1 does not rotate. This ensures that only the twisted yarn is wound up. After winding, the slide block 3 slides in the opposite direction on the slide rail 4, while the roving roll 1 rotates to stretch the roving. The above actions are repeated to complete the twisting, traction, and winding actions to finish spinning.

[0044] When the drum needs to be replaced, the second motor 19 drives the fixed gear 17 to rotate, which in turn drives the transmission gear 18 to rotate. The rotation of the transmission gear 18 allows the threaded rod 29 to slide vertically inside the support base 14 under the limiting action of the limiting shaft 20. The drum, along with the first fixing plate 28, slides down with the threaded rod 29 under gravity until the drum is completely detached from the fixing post 24. At this point, the top of the mating block 33 is still mated to the bottom of the fixing post 24, while the sliding plate 23 on the fixing post 24 is pushed outwards by the elastic force of the first spring 25. When the connecting piece 22 slides and flips, the sliding piece 23 shifts outward from the groove 26. At this time, when the connecting block 33 continues to drive the fixed column 24 to rotate and wind up the yarn, the wound yarn can be directly wrapped around the outside of the sliding piece 23. After the yarn has wound a certain number of turns, manually cut the connection between the yarn on the drum and the sliding piece 23. Then, continue to rotate the threaded rod 29 to make the first fixed piece 28 slide down. The threaded rod 29 continues to slide down until the rotating block 32 on the connecting block 33, which rotates outward under the action of the torsion spring, contacts the inner wall of the slot 34, causing the first fixed piece 28 to press down until the clamping block 27 contacts the top block 31 and... As the clamping block 27 is pushed outward by the compression, to ensure that the clamping block 27 can fully contact the top block 31, the top block 31 can be semi-circular in shape. After the clamping block 27 is pushed outward, it disengages from the contact with the drum. At this time, the lever 36 is activated, which moves the drum of the wound yarn on the first fixing plate 28 to slide along the track frame 21, and moves the unwound drum on the other side of the track frame 21 to the top of the first fixing plate 28. Then, the second motor 19 rotates in the opposite direction, driving the threaded rod 29 to rise through the transmission. When the clamping block 27 disengages from the top block 31, the clamping block 27 is pushed back to its original position by the elastic force of the return spring on the clamping block 27. The drum is clamped and pushed upward by the shims on the threaded rod 29 to raise the first fixing plate 28. During the upward process, the top of the drum will first contact the inclined connecting plate 22. As the threaded rod 29 rises, the drum will push the connecting plate 22 to rotate and reset. The sliding plate 23 will be gradually compressed and the first spring 25 will return to the inside of the slide groove 26. The yarn wound on the sliding plate 23 will fall back onto the drum. The roller 39 pushed by the second spring 38 will contact the side wall of the drum to fix the yarn on the drum, avoiding the problem of relative rotation between the yarn and the drum when the drum rotates, until the threaded rod 29 reconnects with the fixing post 24.
