Description

Technical Field

[0001] This invention belongs to the technical field of ring spinning machines, specifically relating to a ring spinning machine unit equipped with a bidirectional lifting transmission device. Background Technology

[0002] Regarding the lifting and lowering movement of the guide plate and the ring rail in a ring spinning frame, traditional ring spinning frames adopt a unidirectional power drive structure design. The drive structure and transmission device can only be set independently at the rear of the equipment and can be operated in coordination with other execution equipment through electrical control. However, as the market demand for output and production efficiency has become increasingly significant, the number of single ring spinning frames has also increased, leading to the emergence of combined machines and other equipment occupying the market.

[0003] A combined spinning machine refers to the synchronous operation of two or more spinning frames under electrical control to achieve higher production efficiency and lower costs. In a combined spinning machine, the independent power system of each spinning frame can perform its own task. Improving its structure may lead to increased costs. However, the lifting transmission device for the raising and lowering of the guide plate and ring rail is relatively simple in structure. To reduce costs, if the lifting transmission devices of the ring rail and guide plate of the two spinning frames that are set up opposite each other in the combined spinning machine can be integrated, it will save the cost of unified control of two independent lifting transmission devices in electrical control, and also reduce the space and cost occupied by configuring two lifting transmission devices in mechanical structure. Therefore, how to achieve stable and synchronous lifting and transmission of the ring rail and guide plate of two spinning frames in a combined spinning machine, while also taking into account the overall cost reduction of the equipment, is the main direction that those skilled in the art need to tackle. Summary of the Invention

[0004] In view of this, the present invention provides a ring spinning machine with a bidirectional lifting transmission device. The aim is to achieve synchronous and stable transmission of the ring rail and yarn guide plate in the two spinning machines by placing the bidirectional lifting transmission device between the two spinning machines through a special design, while also reducing the overall operating cost of the spinning machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A ring spinning frame with a bidirectional lifting drive includes:

[0007] A spinning frame unit includes two spinning frames with identical structures and models. Each spinning frame includes an execution unit and a drive unit.

The drive unit is used to provide driving force for the spinning action of the execution unit. The execution unit is equipped with a sling-type lifting transmission assembly for the ring rail and the yarn guide plate. The sling-type lifting transmission assembly includes a first hanging chain and a second hanging chain that are respectively connected to the ring rail and the yarn guide plate.

[0008] A bidirectional lifting transmission device is installed between the two spinning machines. The bidirectional lifting transmission device includes a support box, with a support wall plate in the middle of the support box. Furthermore, the support box also includes a drive assembly, a connecting assembly, a ring rail transmission assembly, and a yarn guide plate transmission assembly.

[0009] A drive assembly is installed at the bottom of the support housing. The drive assembly includes a motor and a dual-output shaft reducer. The dual-output shaft reducer transmits power to both sides of the power output shaft.

[0010] The connecting assembly includes two brackets symmetrically arranged on both sides of the drive assembly and two first distribution shafts arranged on both sides of the support wall plate. Each bracket is provided with a winding sprocket, and the two winding sprockets are respectively fixed on the output ends of the power output shaft. In addition, each first distribution shaft is provided with a transmission sprocket, and the two transmission sprockets are connected to the two winding sprockets one-to-one through a first chain.

[0011] The ring rail drive assembly includes two sets, which are respectively mounted on two first distribution shafts. Each set of the ring rail drive assembly includes two ring rail lifting sprockets mounted on the first distribution shaft. Each ring rail lifting sprocket is connected to the first lifting chain in the sling-type lifting drive assembly. The two sets of ring rail drive assemblies are used to draft the ring rails in two spinning machines respectively.

[0012] The yarn guide plate transmission assembly includes two sets, which are respectively mounted on two first distribution shafts. Each set of yarn guide plate transmission assemblies includes a second distribution shaft sleeved on the first distribution shaft and a transmission shaft mounted on a support wall plate. The second distribution shaft is rotatably sleeved on the middle of the first distribution shaft via bearings. The two ends of the transmission shaft are respectively provided with a first yarn guide plate transmission sprocket and a second yarn guide plate transmission sprocket. In addition, the yarn guide plate transmission assembly also includes a third yarn guide plate transmission sprocket mounted on the first distribution shaft and a fourth yarn guide plate transmission sprocket mounted on the second distribution shaft. The first yarn guide plate transmission sprocket and the third yarn guide plate transmission sprocket are connected by a second chain, and the second yarn guide plate transmission sprocket and the fourth yarn guide plate transmission sprocket are connected by a third chain.

[0013] The yarn guide plate transmission assembly also includes two yarn guide plate lifting sprockets located on the second distribution shaft. Each yarn guide plate lifting sprocket is connected to the second suspension chain in the sling-type lifting transmission assembly. The two sets of yarn guide plate transmission assemblies are used to draft the yarn guide plates in the two spinning machines respectively.

[0014] Preferably, in the drive assembly, the dual-output-shaft reducer includes a housing and a reduction system, wherein the housing is used to support the reduction system, wherein:

[0015] The shell is generally rectangular. The shell has a partition plate inside, which divides the internal space of the shell into a worm gear transmission cavity and a gear transmission cavity. The worm gear transmission cavity also has a fixing block with a fixing hole.

[0016] The reduction system includes a shaft system assembly and a gear transmission assembly, wherein:

[0017] The shaft system assembly includes a power input shaft located within the worm gear transmission cavity. The power input shaft extends into the worm gear transmission cavity through a bearing mounting hole pre-set on the housing and engages with a fixing hole. Furthermore, the shaft system assembly includes a first intermediate shaft and a second intermediate shaft. The first intermediate shaft passes through a partition plate, which divides the first intermediate shaft into two parts located within the worm gear transmission cavity and the gear transmission cavity, respectively. The first intermediate shaft and the power input shaft are arranged perpendicularly to each other. The second intermediate shaft is located within the gear transmission cavity and is positioned above the first intermediate shaft. The second intermediate shaft and the power input shaft are on the same horizontal plane. The shaft system assembly also includes a power output shaft. The power output shaft passes through the partition plate, the worm gear transmission cavity, and the gear transmission cavity simultaneously, with its two output ends extending to both sides of the housing.

[0018] The gear transmission assembly includes a worm gear portion on the power input shaft, a worm wheel portion and a first gear on the first intermediate shaft, a second gear on the second intermediate shaft, and a third gear on the power output shaft. Based on the meshing of the worm wheel portion and the worm gear portion, the meshing of the first gear and the second gear, and the meshing of the second gear and the third gear, the operating power transmitted by the dual-output shaft reducer to the reduction system through the power input shaft is transmitted bidirectionally from the two output ends of the power output shaft.

[0019] Preferably, on the housing, the bearing mounting hole is engaged with the power input shaft through a first rolling bearing, and a first through cover is provided on one side of the first rolling bearing. The power input shaft passes through the first through cover, and an oil seal is also provided on the first through cover to seal the gap between the first through cover and the power input shaft.

[0020] Inside the worm gear transmission cavity inside the housing, a second rolling bearing is provided inside the fixing hole. With one end of the power input shaft cooperating with the fixing hole through the second rolling bearing and the other end of the power input shaft cooperating with the bearing mounting hole through the first rolling bearing, the rotation of the power input shaft in the worm gear transmission cavity is realized. In addition, the end of the power input shaft located outside the housing is connected to the motor.

[0021] Preferably, both ends of the first intermediate shaft are engaged with the side wall of the housing via third rolling bearings, and the partition plate is also engaged with the first intermediate shaft via third rolling bearings. Based on the engagement of the three third rolling bearings with the first intermediate shaft, the rotation of the first intermediate shaft within the housing is achieved. In addition, the outer wall of the housing is provided with second caps at positions corresponding to the two ends of the first intermediate shaft, and the gap between the first intermediate shaft and the housing is sealed by the second caps.

[0022] One end of the second intermediate shaft is engaged with the side wall of the housing via a fourth rolling bearing, and the other end of the second intermediate shaft is also engaged with the partition plate via a fourth rolling bearing; in addition, the outer wall of the housing is provided with a third cover at a position corresponding to the end of the second intermediate shaft, and the gap between the second intermediate shaft and the housing is sealed by the third cover.

[0023] Both output ends of the power output shaft are engaged with the side wall of the housing via fifth rolling bearings, and the partition plate is also engaged with the power output shaft via fifth rolling bearings. Based on the engagement of the three fifth rolling bearings with the power output shaft, the rotation of the power output shaft within the housing is achieved. In addition, on the outer wall of the housing, each of the fifth rolling bearings has a second cover on one side, and the two output ends of the power output shaft pass through two second covers respectively. Each second cover is also equipped with an oil seal to seal the gap between the power output shaft and the second cover.

[0024] Preferably, the top of the housing is also provided with a top cover, and the top cover is also provided with a lifting ring and a vent plug, which are used to lift the dual-output shaft reducer and vent the air inside the dual-output shaft reducer, respectively. The bottom of the housing is also provided with a mounting plate, and the mounting plate is provided with a plurality of first mounting holes, and the housing is installed in the support box through the cooperation of the first mounting holes and fixing bolts.

[0025] The housing is also provided with an oil hole, which is located below the bearing mounting hole, and a first cap is also provided on the oil hole to seal the oil hole;

[0026] The housing is also provided with a vernier mounting hole on its side wall, and the vernier mounting hole is located on one side of the power output shaft. The vernier mounting hole is used to install a vernier.

[0027] Preferably, in the bidirectional lifting transmission device, two sets of guide wheel couplings are symmetrically arranged on both sides of the top of the support wall plate. The two sets of guide wheel couplings located on both sides of the support wall plate are used to support the first and second suspension chains of the sling-type lifting transmission components in the two spinning machines.

[0028] Preferably, the first yarn guide plate drive sprocket and the second yarn guide plate drive sprocket on the drive shaft have different diameters.

[0029] The beneficial effects of this invention are as follows:

[0030] In general, the core structure of the bidirectional lifting transmission device of this invention lies in the design of the reducer, the connecting components, the steel collar transmission components, and the yarn guide plate transmission components.

[0031] In this application, the reducer is configured as a dual-output shaft reducer. Specifically, a partition plate is set in the housing to divide the internal space of the housing. Based on the arrangement of the power input shaft, the first intermediate shaft, the second intermediate shaft, and the power output shaft in the housing, the reducer body is designed to be miniaturized. In addition, the present invention also configures the two output ends of the power output shaft to extend to the outside of the housing and be located on both sides of the housing for transmitting power to both sides of the dual-output shaft reducer. This allows the reducer to drive two sets of lifting transmission mechanisms for the steel ring plate and the yarn guide plate in both directions at the same time. This avoids the potential problem of inconsistent lifting actions that may occur when two sets of unidirectional reducers transmit power to two sets of lifting transmission mechanisms separately, and also reduces costs.

[0032] In the connecting assembly, the ring rail transmission assembly, and the yarn guide plate transmission assembly, this application transmits the power of the drive assembly to the two first distribution shafts through the connecting assembly, thereby controlling the synchronicity of the ring rail lifting and lowering movements in the two spinning machines. Simultaneously, both first distribution shafts transmit rotational power to the two transmission shafts via the third yarn guide plate transmission sprocket, the second chain, and the first yarn guide plate transmission sprocket. Both transmission shafts transmit power to the two second distribution shafts via the second yarn guide plate transmission sprocket, the third chain, and the fourth yarn guide plate transmission sprocket, thereby controlling the synchronicity of the yarn guide plate lifting and lowering movements in the two spinning machines. Furthermore, by adjusting the diameters of the first and second yarn guide plate transmission sprockets on the transmission shafts, the difference in lifting speed and height between the two ring rails and the two yarn guide plates in the two spinning machines is adjusted.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] It should be noted in this application that the ring bar and guide plate are the moving mechanisms in the ring spinning machine, which mainly rely on a separate power system to provide the power for their lifting and lowering movements. Considering that the lifting systems of the guide plate and ring bar of a single ring spinning machine are all powered by an independent power system, and that the development trend of ring spinning machines is towards miniaturization of components and cost reduction, this application sets up a bidirectional lifting transmission device for the lifting and lowering movements of the ring bar and guide plate in two ring spinning machines. Relying on this device, the lifting and lowering movements of the ring bar and guide plate in two ring spinning machines are controlled synchronously, achieving synchronous operation and reducing production costs.

[0046] Specifically in this technical solution, such as Figure 1-2 , Figure 6 As shown, a ring spinning machine with a bidirectional lifting transmission device includes: a spinning machine 1 and a bidirectional lifting transmission device 2.

[0047] The spinning frame unit 1 includes two spinning frames 101 with identical structures and models. Each spinning frame 101 includes an execution unit 102 and a drive unit 103. The execution units 102 of the two spinning frames 101 are arranged opposite each other and in a straight line. The drive unit 103 is used to provide driving force for the spinning action of the execution unit 102. The execution unit 102 is equipped with a sling-type lifting transmission assembly for the ring rail and the yarn guide plate. The sling-type lifting transmission assembly includes a first hanging chain 3 and a second hanging chain 4 connected to the ring rail and the yarn guide plate respectively. The first hanging chain 3 and the second hanging chain 4 drive the ring rail and the yarn guide plate to move up and down respectively.

[0048] It should be noted that the technical solution of this application only improves the driving form of the lifting and lowering movement of the yarn guide plate and the ring rail in the spinning machine 101, and does not improve the other parts of the driving part 103 and the execution part 102 in the spinning machine 101, so they will not be described in detail here.

[0049] In this technical solution, such as Figure 1-2 As shown, the bidirectional lifting transmission device 2 is installed between two spinning machines 101. The bidirectional lifting transmission device 2 includes a support box 201, with a support wall plate 202 in the middle of the support box 201. In addition, the support box 201 is also equipped with a drive assembly 5, a connecting assembly 6, a ring rail transmission assembly 7, and a yarn guide plate transmission assembly 8, wherein:

[0050] like Figure 2-4 As shown, the drive assembly 5 is installed at the bottom of the support housing 201. The drive assembly 5 includes a motor and a dual-output shaft reducer 9. The dual-output shaft reducer 9 transmits power to both sides of it through the power output shaft 911.

[0051] Specifically, the dual-output shaft reducer 9 includes a housing 902 and a reduction system. The housing 902 is used to support the reduction system, wherein:

[0052] The housing 902 is generally rectangular. The interior of the housing 902 is provided with a partition plate 903, which divides the interior space of the housing 902 into a worm gear transmission cavity 904 and a gear transmission cavity 905. The worm gear transmission cavity 904 is also provided with a fixing block 906, and the fixing block 906 has a fixing hole 907.

[0053] like Figure 4-5 As shown, the reduction system includes a shaft assembly and a gear transmission assembly, wherein:

[0054] The shaft assembly includes a power input shaft 901 located within the worm gear transmission cavity 904. The power input shaft 901 extends into the worm gear transmission cavity 904 through a bearing mounting hole 908 pre-set on the housing 902 and engages with a fixing hole 907. More specifically, the bearing mounting hole 908 engages with the power input shaft 901 through a first rolling bearing. A second rolling bearing is provided inside the fixing hole 907. With one end of the power input shaft 901 engaging with the fixing hole 907 through the second rolling bearing and the other end of the power input shaft 901 engaging with the bearing mounting hole 908 through the first rolling bearing, the power input shaft 901 can rotate within the worm gear transmission cavity 904. In addition, the end of the power input shaft 901 located outside the housing 902 is connected to a motor to transmit the operating power provided by the motor to the reduction system.

[0055] like Figure 4-5As shown, the shaft system assembly also includes a first intermediate shaft 909 and a second intermediate shaft 910. The first intermediate shaft 909 passes through the partition plate 903 and is divided into two parts located in the worm gear transmission cavity 904 and the gear transmission cavity 905, respectively. The first intermediate shaft 909 and the power input shaft 901 are arranged perpendicular to each other. In addition, both ends of the first intermediate shaft 909 are engaged with the side wall of the housing 902 through third rolling bearings, and the partition plate 903 is also engaged with the first intermediate shaft 909 through third rolling bearings. Based on the engagement of the three third rolling bearings with the first intermediate shaft 909, the rotation of the first intermediate shaft 909 within the housing 902 is realized.

[0056] The second intermediate shaft 910 is located inside the gear transmission cavity 905 and is positioned above the first intermediate shaft 909. Furthermore, the second intermediate shaft 910 and the power input shaft 901 are on the same horizontal plane. One end of the second intermediate shaft 910 is engaged with the side wall of the housing 902 via a fourth rolling bearing, and the other end of the second intermediate shaft 910 is also engaged with the partition plate 903 via a fourth rolling bearing.

[0057] Based on the above embodiments, with the power input shaft 901, the first intermediate shaft 909, and the second intermediate shaft 910 respectively installed inside the housing 902, the second intermediate shaft 910 is positioned above the first intermediate shaft 909, and the second intermediate shaft 910 and the power input shaft 901 are in the same horizontal plane. The first intermediate shaft 909 and the power input shaft 901 are arranged perpendicular to each other. This results in a compact arrangement structure between the power input shaft 901, the first intermediate shaft 909, and the second intermediate shaft 910, which helps to reduce the overall volume of the dual-output shaft reducer and make it miniaturized.

[0058] like Figure 4-5 As shown, the shaft system assembly also includes a power output shaft 911. The power output shaft 911 passes through the partition plate 903, the worm gear transmission cavity 904, and the gear transmission cavity 905. The two output ends of the power output shaft 911 extend to both sides of the housing 902. Both output ends of the power output shaft 911 are engaged with the side wall of the housing 902 through fifth rolling bearings. The partition plate 903 is also engaged with the power output shaft 911 through fifth rolling bearings. Based on the engagement of the three fifth rolling bearings with the power output shaft 911, the rotation of the power output shaft 911 within the housing 902 is realized.

[0059] This completes the arrangement of the shaft system components in the dual-output shaft reducer. Based on this, the power transmission in the dual-output shaft reducer also requires the arrangement of gears between each shaft. Specifically, a gear transmission component is also set up based on the shaft system components.

[0060] like Figure 5As shown, the gear transmission assembly includes a worm gear portion 912 on the power input shaft 901, a worm wheel portion 913 and a first gear 914 on the first intermediate shaft 909, a second gear 915 on the second intermediate shaft 910, and a third gear 916 on the power output shaft 911. Based on the meshing of the worm wheel portion 913 with the worm gear portion 912, the meshing of the first gear 914 with the second gear 915, and the meshing of the second gear 915 with the third gear 916, the operating power transmitted by the dual-output shaft reducer to the reduction system through the power input shaft 901 is transmitted bidirectionally from the two output ends of the power output shaft 911.

[0061] It should be noted here that the reduction ratio in the reducer is determined by factors such as the number of teeth between the gears. In this application, the reduction ratio of the dual-output shaft reducer can be obtained according to actual needs using conventional design methods in the prior art, and the number of teeth and other parameters of each gear can be calculated from there. This application only improves and explains the bidirectional transmission form of the lifting system in the spinning machine unit 1, and does not limit the specific reduction ratio and other parameters.

[0062] In addition, this application also considers the sealing performance of the dual-output shaft reducer during normal operation, specifically, as follows: Figure 3 As shown, this application also provides a first through cover 917 on one side of the first rolling bearing, through which the power input shaft 901 passes. An oil seal is also fitted on the first through cover 917 to seal the gap between the first through cover 917 and the power input shaft 901. The outer wall of the housing 902 also provides a second cover 918 at positions corresponding to the two ends of the first intermediate shaft 909, sealing the gap between the first intermediate shaft 909 and the housing 902. The outer wall of the housing 902 also provides a third cover 919 at positions corresponding to the ends of the second intermediate shaft 910, sealing the gap between the second intermediate shaft 910 and the housing 902. On the outer wall of the housing 902, a second through cover 920 is provided on one side of each fifth rolling bearing. The two output ends of the power output shaft 911 pass through two second through covers 920 respectively, and an oil seal is also fitted on each second through cover 920 to seal the gap between the power output shaft 911 and the second through cover 920.

[0063] In this technical solution, such as Figure 3As shown, the top of the housing 902 is also provided with a top cover 921, and the top cover 921 is also provided with a lifting ring 922 and a vent plug 923, which are used to lift the dual-output shaft reducer and to vent the air inside the dual-output shaft reducer, respectively. The bottom of the housing 902 is also provided with a mounting plate 924, which is provided with several first mounting holes 925. The housing 902 is installed in the support box 201 through the cooperation of the first mounting holes 925 and the fixing bolts. The housing 902 is also provided with an oil hole, which is located below the bearing mounting hole 908. The oil hole is also provided with a first cap 926 for sealing the oil hole. The side wall of the housing 902 is also provided with a vernier mounting hole, which is located on one side of the power output shaft 911. The vernier mounting hole is used to install a vernier 927.

[0064] Therefore, based on the above configuration of the drive component 5, this application will transmit the power of the drive component 5 to the sling-type lifting transmission components for the ring rail and the yarn guide plate in the two spinning machines 101 simultaneously through the cooperation of the connecting component 6, the ring rail transmission component 7 and the yarn guide plate transmission component 8, and ensure that all ring rails and all yarn guide plates in the two spinning machines 101 achieve synchronous lifting.

[0065] Specifically, such as Figure 6-7 As shown, the connecting component 6 includes two supports 601 symmetrically arranged on both sides of the drive component 5, and two first distribution shafts 602 arranged on both sides of the support wall plate 202. Each support 601 is provided with a winding sprocket 603. The two winding sprockets 603 are respectively fixed on the output ends of the power output shaft 911. In addition, each first distribution shaft 602 is provided with a transmission sprocket 604, and the two transmission sprockets 604 are connected to the two winding sprockets 603 one-to-one through the first chain 605.

[0066] Based on the above embodiments, the two output ends of the power output shaft 911 in the drive assembly 5 are supported and positioned by the support 601 and the winding sprocket 603; when the drive assembly 5 drives the power output shaft 911 to rotate, the power output shaft 911 drives the two winding sprockets 603 connected to it to rotate, and the two winding sprockets 603 drive the transmission sprocket 604 to rotate through the first chain 605 connected to them, thereby causing the first distribution shafts on both sides of the support wall plate 202 to rotate in opposite directions.

[0067] like Figure 2 , Figure 6-7As shown, the ring rail transmission assembly 7 includes two sets, which are respectively mounted on two first distribution shafts 602. Each set of ring rail transmission assemblies 7 includes two ring rail lifting sprockets 701 mounted on the first distribution shaft 602. Each ring rail lifting sprocket 701 is connected to the first lifting chain 3 in the sling-type lifting transmission assembly. The two sets of ring rail transmission assemblies 7 are used to draft the ring rails in the two spinning machines 101 respectively.

[0068] Based on the above embodiments, when the drive component 5 drives the first distribution shafts 602 on both sides of the support wall plate 202 to rotate towards or away from each other, each first distribution shaft 602 drives the two ring plate lifting sprockets 701 on it to rotate. When each ring plate lifting sprocket 701 rotates, it pulls the ring plate in the spinning machine 101 up or down through the first chain 3.

[0069] like Figure 2 , Figure 6-9 As shown, the yarn guide plate transmission assembly 8 includes two sets, which are respectively mounted on two first distribution shafts 602. Each set of yarn guide plate transmission assemblies 8 includes a second distribution shaft 801 sleeved on the first distribution shaft 602 and a transmission shaft 802 mounted on the support wall plate 202.

[0070] The second distribution shaft 801 is rotatably sleeved on the middle part of the first distribution shaft 602 via bearings. The two ends of the transmission shaft 802 are respectively provided with a first yarn guide plate transmission sprocket 803 and a second yarn guide plate transmission sprocket 804. In addition, the yarn guide plate transmission assembly 8 also includes a third yarn guide plate transmission sprocket 805 provided on the first distribution shaft 602 and a fourth yarn guide plate transmission sprocket 806 provided on the second distribution shaft 801. The first yarn guide plate transmission sprocket 803 and the third yarn guide plate transmission sprocket 805 are connected by a second chain 807, and the second yarn guide plate transmission sprocket 804 and the fourth yarn guide plate transmission sprocket 806 are connected by a third chain 808.

[0071] The yarn guide plate transmission assembly 8 also includes two yarn guide plate lifting sprockets 809 disposed on the second distribution shaft 801. Each yarn guide plate lifting sprocket 809 is connected to the second hanging chain 4 in the sling-type lifting transmission assembly. The two sets of yarn guide plate transmission assemblies 8 are used to draft the yarn guide plates in the two spinning machines 101 respectively.

[0072] Based on the above embodiments, while the first distribution shaft 602 rotates, the transmission shaft 802 is driven to rotate through the third guide plate transmission sprocket 805, the second chain 807, and the first guide plate transmission sprocket 803. The transmission shaft 802 drives the second distribution shaft 801 to rotate through the second guide plate transmission sprocket 804, the third chain 808, and the fourth guide plate transmission sprocket 806. While the second distribution shaft 801 rotates outside the first distribution shaft 602, the guide plate lifting sprocket 809 and the second hanging chain 4 drive the guide plate in the spinning frame 101 to rise or fall.

[0073] In addition, such as Figure 7 As shown, in the bidirectional lifting transmission device 2, two sets of guide wheel couplings 203 are symmetrically arranged on both sides of the top of the support wall plate 202. The two sets of guide wheel couplings 203 located on both sides of the support wall plate 202 are used to support the first hanging chain 3 and the second hanging chain 4 of the sling-type lifting transmission assembly in the two spinning machines 101. On the transmission shaft 802, the first guide plate transmission sprocket 803 and the second guide plate transmission sprocket 804 have different diameters.

[0074] Based on the above embodiments, since the first yarn guide plate drive sprocket 803 and the second yarn guide plate drive sprocket 804 have different diameters, the first yarn guide plate drive sprocket 803 and the second yarn guide plate drive sprocket 804 at both ends of the same drive shaft 802 have different linear velocities. The first yarn guide plate drive sprocket 803 is connected to the third yarn guide plate drive sprocket 805 through the second chain 807, so the first yarn guide plate drive sprocket 803 and the third yarn guide plate drive sprocket 805 have the same linear velocity. The third yarn guide plate drive sprocket 805 has the same angular velocity as the first distribution shaft 602 and the steel collar lifting sprocket 701. The second yarn guide plate drive sprocket 804 is connected to the fourth yarn guide plate drive sprocket 806 through the third chain 808, so the second yarn guide plate drive sprocket 804 and the fourth yarn guide plate drive sprocket 806 have the same linear velocity. The fourth yarn guide plate drive sprocket 806 has the same angular velocity as the second distribution shaft 801 and the yarn guide plate lifting sprocket 809.

[0075] Therefore, by adjusting the diameter of the first yarn guide plate drive sprocket 803 and the second yarn guide plate drive sprocket 804 at both ends of the drive shaft 802, the rotational speed of the second distribution shaft 801 and the yarn guide plate lifting sprocket 809 can be adjusted. By adjusting the rotational speed of the yarn guide plate lifting sprocket 809, the lifting speed and lifting height of the yarn guide plate in the spinning machine 101 can be adjusted.

[0076] In general, the core structure of the bidirectional lifting transmission device 2 in this invention lies in the design of the reducer, the connecting component 6, the steel collar plate transmission component 7, and the yarn guide plate transmission component 8.

[0077] In this application, the reducer is configured as a dual-output shaft reducer 9. Specifically, a partition plate 903 is provided in the housing 902. Based on the division of the internal space of the housing 902 by the partition plate 903, the arrangement of the power input shaft 901, the first intermediate shaft 909, the second intermediate shaft 910, and the power output shaft 911 in the housing 902 is designed to make the body of the dual-output shaft reducer 9 more compact. On this basis, the present invention also configures the two output ends of the power output shaft 911 to extend to the outside of the housing 902 and be located on both sides of the housing 902 for transmitting power to both sides of the dual-output shaft reducer 9. This enables the reducer to drive two sets of lifting transmission mechanisms for the steel collar plate and the yarn guide plate in both directions at the same time. This avoids the potential for inconsistent lifting actions of the two lifting transmission mechanisms when two sets of unidirectional reducers transmit power to the two sets of lifting transmission mechanisms separately, and also reduces costs.

[0078] In the connecting assembly 6, the ring rail transmission assembly 7, and the yarn guide plate transmission assembly 8, this application transmits the power of the drive assembly 5 to the two first distribution shafts 602 through the connecting assembly 6, thereby controlling the synchronicity of the ring rail lifting and lowering movements in the two spinning machines 101; at the same time, both first distribution shafts 602 transmit rotational power to the two transmission shafts 802 through the third yarn guide plate transmission sprocket 805, the second chain 807, and the first yarn guide plate transmission sprocket 803, and both transmission shafts 802... Power is transmitted to two second distribution shafts 801 via the second guide plate drive sprocket 804, the third chain 808, and the fourth guide plate drive sprocket 806, thereby controlling the synchronicity of the lifting and lowering movements of the guide plates in the two spinning machines 101. Based on this, the difference in lifting speed and height between the two ring rails and the two guide plates in the two spinning machines 101 is adjusted by adjusting the diameter of the first guide plate drive sprocket 803 and the second guide plate drive sprocket 804 on the drive shaft 802.

[0079] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
