Description

TECHNICAL FIELD

[0001] The present application relates to a fine spinning machine that is not prone to breaking, and belongs to the technical field of textile machinery equipment. BACKGROUND

[0002] The existing fine spinning machine, as shown in Chinese patent application "Application Publication No. CN113279094A; Application Publication Date: August 20, 2021; Name: Fine Spinning Machine Safety Protection System", includes a roving frame, a drafting mechanism, a ring rail, a fine spinning frame, and a collective doffing device arranged in sequence from top to bottom. A plurality of roving bobbins are hung on the roving frame. A fine spinning bobbin is detachably arranged on the insertion rod of the fine spinning frame. The ring rail is arranged above the fine spinning frame by a vertical moving device. The ring rail is provided with a through hole for the fine spinning bobbin. The collective doffing device is used to replace the fine spinning bobbin on the fine spinning frame with an empty fine spinning bobbin on the bottom horizontal moving device. The collective doffing device is composed of two or more than two herringbone-shaped pushing mechanisms arranged side by side. When the vertical pushing belt gripping part is pushed, the cross beam moves horizontally, making it difficult for the gripping part to be connected with the fine spinning bobbin. In addition, the yarn from the roving bobbin directly enters the drafting device for processing, which is prone to breaking due to insufficient yarn tension. SUMMARY

[0003] The purpose of the present application is to overcome the above technical defects of the existing fine spinning machine, and provide a new fine spinning machine. The yarn tension of the fine spinning machine is increased by fumigation in a high-temperature steam cover, which can effectively prevent yarn breakage, reduce material loss, and improve production efficiency. In addition, the arrangement and structure of the herringbone-shaped pushing mechanism are also optimized and designed, which realizes stable pushing of the cross beam in the vertical direction, realizes rapid and accurate connection of the gripping part and the fine spinning bobbin, and improves the production efficiency.

[0004] The above technical purpose of the present application is achieved by the following technical scheme:

[0005] A fine spinning machine that is not prone to breaking, including a roving frame, a drafting mechanism, a ring rail, a fine spinning frame, and a collective doffing device arranged in sequence from top to bottom. A plurality of roving bobbins are hung on the roving frame. A fine spinning bobbin is detachably arranged on the insertion rod of the fine spinning frame. The ring rail is arranged above the fine spinning frame by a vertical moving device. The ring rail is provided with a through hole for the fine spinning bobbin. The collective doffing device is used to replace the fine spinning bobbin on the fine spinning frame with an empty fine spinning bobbin on the bottom horizontal moving device. A steam cover is arranged between the roving frame and the drafting mechanism. A through hole for vertically penetrating the roving yarn is arranged in the steam cover. A protruding annular table is arranged on the inner side of the lower opening of the through hole. Hot water is filled in the upper surface of the steam cover bottom plate around the annular table. An electric heating element is embedded in the steam cover bottom plate around the annular table.

[0006] By adopting the technical scheme, a new spinning frame is provided.

[0007] Further, the surface of the annular table is smooth, and the upper opening of the through hole is provided with an inner ring smooth annular structure.

[0008] By adopting the technical scheme, the upper and lower openings of the through hole are provided with smooth structures, so that the breakage of the silk thread can be effectively avoided.

[0009] Further, the collective doffing device comprises parallel beams, a rotating rod and a pushing assembly arranged between the beams and the rotating rod, the rotating rod is rotatably arranged on the ground through a bearing seat, the beams are provided with gripping components for the spinning bobbin, the pushing assembly comprises two symmetrically arranged pushing mechanisms, the pushing mechanism comprises a long rod and a short rod, the lower end of the short rod is hingedly connected to a fixed block of the rotating rod, the upper end of the short rod is hingedly connected to the middle of the long rod, the lower end of the long rod is hingedly connected to a lower sliding sleeve slidingly arranged on the rotating rod, the upper end of the long rod is hingedly connected to an upper sliding sleeve slidingly arranged on the beam, the two pushing mechanisms are symmetrically arranged in a form of facing the lower sliding sleeves, an extension push rod is arranged between the lower sliding sleeves of the two pushing mechanisms, and the extension push rod is fixed to the rotating rod.

[0010] By adopting the technical scheme, the two pushing mechanisms are symmetrically arranged, and the extension push rod fixedly arranged between the two pushing mechanisms is used for pushing, so that the horizontal movement of the beam can be avoided when the pushing mechanism pushes the beam vertically, the gripping component and the spinning bobbin can be quickly and accurately connected, and the production efficiency is improved.

[0011] Further, the outer side wall of the beam is provided with an axial straight groove, the upper side wall or the lower side wall of the axial straight groove is provided with a rack, and the inner side of the upper sliding sleeve is rotatably arranged with a gear through a side pin shaft.

[0012] By adopting the technical scheme, the gear and the rack are arranged between the upper sliding sleeve of the pushing mechanism and the beam, so that the horizontal movement distance of the upper sliding sleeve of the pushing mechanism on the beam can be further ensured to be consistent, and the horizontal movement of the beam can be further ensured not to occur when the beam moves vertically.

[0013] A further feature of the present invention is that when a rack is provided on the upper sidewall of the axial straight groove, the middle pin of the long rod at the upper end is rotatably mounted on the transverse slider in the transverse straight hole of the upper sleeve. Vertical sliders are respectively installed in the vertical straight holes on the outer sides of both ends of the transverse straight hole. Gears are rotatably mounted on the inner side of the vertical slider using side pins. Wedge-shaped push blocks are provided on both sides of the transverse slider for the two side pins. When the wedge-shaped push blocks on both sides of the middle pin push one side pin pushes up and makes the gear on it mesh with the rack on the upper sidewall of the axial straight groove, the other side pin and its gear disengage from the rack on the upper sidewall of the axial straight groove under the action of gravity. The two side pins and their gears are unidirectional rotating gears. The gear on the left side can only rotate clockwise, and the gear on the right side can only rotate counterclockwise.

[0014] By adopting the above technical solution, the unidirectional movement of the upper sliding sleeve during the pushing process is realized, which can effectively avoid the situation where the two upper sliding sleeves move inconsistently due to slippage or other issues during the pushing process, and further ensure that the crossbeam does not move laterally during vertical pushing.

[0015] A further feature of the present invention is that the rotation of the rotating rod is driven by a servo motor at the end, the lower sleeve and the rotating rod cannot rotate, and the lower sleeve can only move axially on the rotating rod.

[0016] By adopting the above technical solution, the driving method of the rotating rod is limited.

[0017] A further configuration of the present invention is that the roving frame, steam hood, drafting mechanism, ring rail, and spinning frame are arranged between the head and tail of the machine.

[0018] By adopting the above technical solution, the specific placement methods of the roving frame, steam hood, drafting mechanism, ring rail, and spinning frame are defined.

[0019] The main beneficial effects of this invention are:

[0020] 1. The yarn of the spinning machine of the present invention is steamed in a high-temperature steam hood, which increases the tension of the yarn, effectively prevents yarn breakage, reduces raw material loss, and improves production efficiency.

[0021] 2. The spinning machine of the present invention has two symmetrically arranged herringbone arm pushing mechanisms and uses telescopic push rods fixedly placed between the two herringbone arm pushing mechanisms for pushing. This can realize that when the herringbone arm pushing mechanism pushes the crossbeam vertically, the crossbeam does not move laterally. This realizes the quick and accurate docking of the gripping component and the spinning drum, and improves production efficiency.

[0022] 3. The spinning machine of the present invention realizes the unidirectional movement of the upper sliding sleeve during the pushing process, which can effectively avoid the situation where the two upper sliding sleeves move inconsistently due to slippage or other issues during the pushing process, and can further ensure that the crossbeam does not move laterally during vertical pushing.

[0031] Example 1:

[0032] like Figures 1 to 5As shown, a fine spinning machine not easy to break line, including from top to bottom in turn arranged roving frame 2, drafting mechanism 5, ring rail plate 6, spinning frame 8 and collective doffing device, roving frame 2 on the hoisting several roving 3, spinning frame 8 on the insertion rod detachable spinning bobbin, ring rail plate 6 is arranged in the upper part of the spinning frame 8 using vertical movement device, ring rail plate 6 is provided with the through hole for spinning bobbin, collective doffing device for spinning frame 8 on the spinning bobbin and the bottom transverse movement device on the empty spinning bobbin replacement, roving frame 2 and drafting mechanism 5 between the installation of steam cover 4, roving frame 2, steam cover 4, drafting mechanism 5, ring rail plate 6 and spinning frame 8 are arranged between the head 1 and tail 7.

[0033] Steam cover 4 is arranged in the through hole of the vertical through roving line, the inner side of the lower opening along the through hole is provided with a convex annular table 26, the outer periphery of the annular table 26 is filled with hot water 27 on the bottom plate of the steam cover 4, and the bottom plate of the steam cover 4 is embedded with an electric heating element. The surface of the annular table 26 is smooth and round, and the upper opening of the through hole is provided with an inner ring smooth and round annular structure 31.

[0034] The collective doffing device includes a transverse beam 9, a rotating rod 28 and a pushing assembly arranged between the transverse beam 9 and the rotating rod 28, the rotating rod 28 is rotatably arranged on the ground through a bearing seat 29, the transverse beam 9 is arranged with a gripping part 10 for the spinning bobbin, the pushing assembly includes two pushing mechanisms arranged symmetrically, the pushing mechanism includes a long rod 13 and a short rod 12, the lower end of the short rod 12 is hinged to the fixed block 11 of the rotating rod 2, the upper end of the short rod 12 is hinged to the middle of the long rod 13, the lower end of the long rod 13 is hinged to the lower sliding sleeve 14 slidingly arranged on the rotating rod 28, the upper end of the long rod 13 is hinged to the upper sliding sleeve 16 slidingly arranged on the transverse beam 9, the two pushing mechanisms are symmetrically arranged in the form of facing each other with the lower sliding sleeve 14, the lower sliding sleeve 14 between the two pushing mechanisms is provided with a telescopic push rod 15, and the telescopic push rod 15 is fixed on the rotating rod 28. The rotation of the rotating rod 28 is driven by the servo motor 30 at the end, the lower sliding sleeve 14 cannot rotate between the rotating rod 28, and the lower sliding sleeve 14 can only move axially on the rotating rod 28.

[0035] When the upper side wall of the axial straight slot 17 is provided with the rack 18, the middle pin shaft at the upper end of the long rod 13 is rotatably arranged on the horizontal slider 22 in the horizontal straight hole 21 in the upper sliding sleeve 16, the vertical straight holes 19 at the outer sides of both ends of the horizontal straight hole 21 are respectively arranged with vertical sliders 20, the inner sides of the vertical sliders 20 are rotatably arranged with the gear wheels 25 through the side pin shafts 23, and the two sides of the horizontal slider 22 are provided with wedge-shaped push blocks 24 corresponding to the two side pin shafts 23. When the wedge-shaped push blocks 24 on both sides of the middle pin shaft push the side pin shaft 23 on one side and make the gear wheel 25 thereon engage with the rack 18 on the upper side wall of the axial straight slot 17, the side pin shaft 23 on the other side and the gear wheel 25 thereon are disengaged from the rack 18 on the upper side wall of the axial straight slot 17 under the action of gravity. Both the side pin shafts 23 and the gear wheels 25 thereon are one-way rotating gear wheels, and the gear wheel 25 on the left side can only rotate clockwise, and the gear wheel 25 on the right side can only rotate counterclockwise.

[0036] Principle of use:

[0037] When the yarn unwound from the roving 3 passes through the vertical through hole of the air inlet cover, the fumigation of steam increases the tension and reduces the probability of breakage. As shown in the figure, the long rod 13 of the two-character arm pushing mechanism swings towards each other and is in the process of vertically pushing the cross beam 9. At this time, the gear wheels 25 on the sides of the two upper sliding sleeves 16 move upwards and engage with the rack 18, and the gear wheels 25 on the sides away from the two upper sliding sleeves 16 move downwards and disengage from the rack 18. Since the engaged gear wheels 25 can only rotate in one direction at this time, only the movement of the two upper sliding sleeves 16 towards each other can be achieved (the movement of the two upper sliding sleeves 16 away from each other cannot be achieved). When the cross beam 9 needs to be vertically moved downwards, the gear wheels 25 on the sides of the two upper sliding sleeves 16 move downwards and disengage from the rack 18, and the gear wheels 25 on the sides away from the two upper sliding sleeves 16 move upwards and engage with the rack 18. Since the gear wheels 25 away from each other can only rotate in one direction, only the movement of the two upper sliding sleeves 16 away from each other can be achieved. This scheme can effectively ensure that the two upper sliding sleeves 16 move towards or away from each other by the same distance, and can effectively ensure that the cross beam 9 does not move horizontally when the cross beam 9 is vertically pushed.

[0038] Example two:

[0039] The difference between example two and example one is that the outer side wall of the cross beam 9 is provided with an axial straight slot 17, the upper side wall or the lower side wall of the axial straight slot 17 is provided with a rack 18, and the inner side of the upper sliding sleeve 16 is rotatably arranged with a gear wheel 25 through a side pin shaft 23. The gear wheel 25 engages with the rack 18 in the axial straight slot 17. The cooperation of the gear wheel 25 and the rack 18 in this scheme can control the movement distance of the two upper sliding sleeves 16 to a certain extent, but because it does not have a reverse locking function, its ability to keep the cross beam 9 from moving horizontally when pushing the cross beam 9 is slightly weaker than that of example one.
