[0002] The ring spinning frame is an important machine in the textile industry, and is an important process for realizing the conversion from roving to yarn. In the yarn spinning process, the drafting transmission system is an important link for realizing the conversion from roving to yarn, and is realized by differentiating the rotation speeds of front, middle and rear rollers and clamping fibers by corresponding rollers.

[0003] As a main component in the textile equipment, the roller driving assembly is generally driven to rotate by the synchronous shaft of the roller gear box. In the prior art, one driving motor drives multiple rollers to rotate by cooperating with multiple gear sets.

[0030] Referring to Figure 1 , Figure 2 The roller drive mechanism 2 mainly comprises a motor for driving the front roller rod 4, the middle roller rod 5 and the rear roller rod 6 to rotate, and a synchronous shaft 23 for linkage transmission, wherein the front roller rod 4, the middle roller rod 5 and the rear roller rod 6 are distributed and installed on the first mounting plate 101 and the second mounting plate 102, one end of the front roller rod 4 and the rear roller rod 6 is rotationally connected with the second mounting plate 102, the other end extends away from the second mounting plate 102, one end of the middle roller rod 5 penetrates through the second mounting plate 102 and is rotationally connected with the first mounting plate 101, the other end extends away from the second mounting plate 102, the motor can drive the front roller rod 4 and the middle roller rod 5 to rotate synchronously, and the rear roller rod 6 rotates alone, and the rotating speed of the rear roller rod 6 is faster than that of the front roller rod 4 and the middle roller rod 5.

[0031] Referring to Figure 1 , Figure 2 and Figure 3 In the embodiment, the motor mainly comprises a main transmission motor 21 and a secondary transmission motor 22, wherein the main transmission motor 21 is installed on one side of the second mounting plate 102, the secondary transmission motor 22 is installed on one side of the first mounting plate 101, the synchronous shaft 23 is arranged between the first mounting plate 101 and the second mounting plate 102, one end of the synchronous shaft 23 is rotationally connected with the first mounting plate 101 and is drivingly connected with the middle roller rod 5 through a synchronous belt, the other end is close to the second mounting plate 102 and is drivingly connected with the front roller rod 4 through a synchronous belt, the output end of the secondary transmission motor 22 is drivingly connected with one end of the synchronous shaft 23 through a synchronous belt, the secondary transmission motor 22 drives the synchronous shaft 23 to rotate, and the synchronous shaft 23 drives the front roller rod 4 and the middle roller rod 5 to rotate synchronously.

[0032] Since the rotating speed of the front roller rod 4 and the middle roller rod 5 is slow, in order to ensure that the front roller rod 4 and the middle roller rod 5 can rotate at a low speed, a speed reducer 14 is further arranged on the first mounting plate 101 and the second mounting plate 102, one end of the front roller rod 4 and the middle roller rod 5 is connected with the output end of the speed reducer 14, and the input end of the two speed reducers 14 is connected with the two ends of the synchronous shaft 23 through a synchronous belt, the power output by the secondary transmission motor 22 drives the synchronous shaft 23 to rotate at a high speed, and the power output by the synchronous shaft 23 is transmitted to the two speed reducers 14, and the front roller rod 4 and the middle roller rod 5 are driven to rotate at a low speed after being reduced by the speed reducer 14.

[0033] A gear box 13 is further arranged on the side of the second mounting plate 102, the output end of the main transmission motor 21 is connected with the gear box 13, and the gear box 13 is further connected with the rear roller rod 6 through a synchronous belt, thereby driving the rear roller rod 6 to rotate.

[0034] As shown in Figure 1 and Figure 2 , the first mounting plate 101 and the second mounting plate 102 are slidably arranged on the two fixed bottom rods 31, in order to fix the mounting plates, a plurality of positioning holes 311 are arranged on each fixed bottom rod 31 at equal intervals, and when the first mounting plate 101 and the second mounting plate 102 are adjusted to the right position, the fasteners are selectively connected with the corresponding positioning holes 311 on the fixed bottom rod 31, so that a stable supporting and mounting structure is formed.

[0035] It should be noted that the positioning hole 311 is a threaded hole (which can also be a smooth hole), the bottom of the mounting plate is threadedly connected with the corresponding positioning hole 311 through a bolt, the connection is more compact, and of course, a threaded hole can not be used here, and the connection is not affected.

[0036] As shown in Figure 1 , in order to prevent the mounting plate from tilting left and right on the fixed bottom rod 31, a semi-annular supporting plate 7 is arranged at the bottom of the first mounting plate 101 and the second mounting plate 102, which plays a limiting and supporting role, and a shape matching the fixed bottom rod 31 is formed at the bottom of the first mounting plate 101 and the second mounting plate 102, the supporting plate 7 can be stacked with the bottom of the mounting plate and then fixedly connected with the fixed bottom rod 31 through a bolt, or the supporting plate 7 can be integrally connected with the side of the mounting plate, and then the bottom of the mounting plate and the supporting plate 7 are fixedly connected with the fixed bottom rod 31 through a bolt, the supporting plate 7 can pass through one side of the mounting plate or both sides of the mounting plate, and can play a supporting role, prevent the mounting plate from tilting left and right on the fixed bottom rod 31, and improve the stability of the whole structure.

[0037] As shown in Figure 4 and Figure 5As shown in the drawings, a plurality of gear mounting positions and at least one motor mounting position are arranged on each mounting plate, the motor mounting position on the second mounting plate 102 is used for mounting the main transmission motor 21, and the motor mounting position on the first mounting plate 101 is used for mounting the fixed secondary transmission motor 22. Two motor mounting positions can be arranged, that is, two secondary transmission motors 22 can be mounted, so that two groups of roller rods are arranged on the mounting plate in a symmetrical manner, and each group of roller rods includes a front roller rod 4, a middle roller rod 5 and a rear roller rod 6. The two secondary transmission motors 22 can respectively drive the front roller rod 4 and the middle roller rod 5 of the two groups of roller rods to rotate, and the gear box 13 has two output ends, so that one main transmission motor 21 can drive the two rear roller rods 6 to rotate. In this way, the driving of the two groups of roller rods is realized without changing the simplicity of the overall structure, and the gear mounting positions are used for mounting the gears used by the roller driving mechanism 2 in the transmission process.

[0038] As shown in the drawings, Figure 4 and Figure 5 A plurality of long circular holes 12 of different sizes are arranged on the first mounting plate 101 and the second mounting plate 102, the spacing between the secondary transmission motor 22 and the synchronous shaft 23 in the middle roller driving mechanism 2 can be adjusted through the long circular holes 12, and the long circular holes 12 are also used to connect the reduction box 14 and the first mounting plate 101 and the second mounting plate 102. However, the long circular hole 12 used for mounting and fixing the reduction box 14 is arranged in an inclined manner, and the inclination angle is consistent with the inclination angle between the front roller rod 4, the middle roller rod 5 and the rear roller rod 6. In this way, the spacing between the front roller rod 4, the middle roller rod 5 and the rear roller rod 6 can be adjusted.

[0039] As shown in the drawings, Figure 1 and Figure 2 In order to fix the main transmission motor 21, a fixing seat 10 is arranged at the bottom of the main transmission motor 21, and the fixing seat 10 is fixed on the two fixed bottom rods 31. The fixing seat 10 is made of profile steel, which is convenient for processing.

[0040] As shown in the drawings, Figure 1 A tensioning wheel 11 is arranged on one side of the first mounting plate 101 and the second mounting plate 102, which is used to adjust the tension of the synchronous belt in the roller driving mechanism 2, so as to prevent the front roller rod 4 and the middle roller rod 5 from rotating synchronously due to insufficient tension of the synchronous belt.

[0041] As shown in the drawings, Figure 1 and Figure 2Two connecting strips 9 are arranged between the two mounting plates, and the connecting strips 9 can be arranged on one side of the two mounting plates, or on both sides, or on three sides. In the figure, the two connecting strips 9 are arranged on both sides of the mounting plate, so that the two mounting plates and the two fixed bottom bars 31 form a fixed support together, and the overall stability is higher. In order to strengthen the structural strength of the edge of the mounting plate, the top and the two side edges of the mounting plate are bent to one side perpendicular to the mounting surface (i.e. three sides except the bottom) to improve the structural strength. In this way, one side of the mounting plate forms a large groove, which can reduce the overall structural weight and save material cost. It should be noted that the middle position of the structure formed by bending the top of the mounting plate to one side perpendicular to the mounting surface is thicker than other positions, which can improve the structural strength of the position and prevent the top of the mounting plate from being crushed.

[0042] As shown in Figure 1 , a pillow block 8 is arranged at the bottom of the two fixed bottom bars 31, and the pillow block 8 is formed with a shape matching the fixed bottom bar 31, which serves as a limiting support.

[0043] In general, the overall structure of the roller driving mechanism 2 is much more optimized than the prior art, and the overall structure is more simple and compact, easy to disassemble and maintain, and without complex gear transmission structure, the transmission effect is good, and the gear transmission process is not prone to shaking and abnormal noise, and the transmission stability is high.

[0044] The above technical solution only embodies the preferred technical solution of the technical solution of the present application, and some changes made by the person skilled in the art to some parts thereof also embody the principle of the present application and are within the protection scope of the present application.
