Description

Technical Field

[0001] This utility model belongs to the field of textile machinery and equipment, and specifically relates to a transmission tube drive device for a ring spinning machine. Background Technology

[0002] Ring spinning machines are the most widely used mechanical equipment in the textile industry. In order to reduce labor costs, ring spinning machines are equipped with an automatic collective doffing system, which specifically involves the inward and outward swinging motion and the up and down lifting motion of the tube gripper. The lifting motion of the tube gripper is achieved by the translational movement of the long arm end of the herringbone arm along the length of the spinning machine following the transmission tube. The inward and outward swinging motion of the tube gripper is achieved by the translational device set on the air frame.

[0003] In existing ring spinning machine systems, two drive tubes are connected to two screw boxes, and a single motor drives both screw boxes simultaneously via two coaxially mounted toothed pulleys and two toothed belts, thereby controlling the operation of both drive tubes. However, this driving method is prone to damage to the toothed belt on one side. This results in a situation where one side of the air frame is running while the other side has stopped its vertical movement, but the inward and outward swinging motion of both air frames continues, easily causing damage to components. Furthermore, using two sets of screw boxes to simultaneously drive two drive tubes can lead to asynchronous operation of the two drive tubes if one side experiences tooth skipping, causing further damage to components. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a drive device for the transmission tubes of a ring spinning machine, which abandons the design of using two sets of screw boxes to drive two transmission tubes separately, and uses one set of screw drive device to drive two transmission tubes simultaneously, ensuring that the transmission tubes on both sides of the ring spinning machine operate synchronously and reducing the later maintenance costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A drive tube device for a ring spinning frame, applied in the ring spinning frame's loading system, includes drive tubes disposed on both sides of the ring spinning frame body. The ring spinning frame body also includes a frame base plate. The drive tube device includes:

[0007] The power assembly is mounted on the base plate of the frame via an L-shaped mounting plate. The power assembly includes a motor, the output end of which is connected to a gearbox. The output end of the gearbox is provided with a first transmission pulley. The gearbox reduces the power provided by the motor and transmits it to the first transmission pulley.

[0008] A transmission assembly includes a screw box that is generally rectangular in shape. A screw is rotatably mounted inside the screw box. The screw includes a transmission section and a working section. The transmission section passes through the screw box and extends to the outside of the screw box. A second transmission pulley is provided at the end of the transmission section. The first transmission pulley and the second transmission pulley are connected by a transmission belt for transmitting the power provided by the power assembly to the screw.

[0009] Furthermore, the working section of the lead screw is located inside the lead screw box, and two transmission nuts are threadedly connected to the outer wall of the working section. The two transmission nuts are connected to a connecting pipe, which is sleeved on the outer wall of the working section without interfering with it. A set of guide rods are arranged parallel to each other on both sides of the connecting pipe, and the two ends of the set of guide rods are fixedly connected to the inner wall of the lead screw box. Both transmission nuts are slidably sleeved on the outer wall of the set of guide rods. At the same time, one end of the connecting pipe extends from the side of the lead screw box away from the second transmission pulley to the outside of the lead screw box.

[0010] A push plate is disposed between the two transmission tubes and is fixedly connected to the two transmission tubes. In addition, the push plate is also connected to the end of the connecting tube located outside the screw box via a connecting assembly.

[0011] The reinforcing assembly includes a set of symmetrically arranged reinforcing plates, wherein one end of each reinforcing plate is connected to the top of the push plate, and the other end is connected to two transmission pipes respectively.

[0012] Preferably, in the transmission assembly, the working section of the lead screw has a length of 1450 mm, and the distance between the two transmission nuts is 700 mm.

[0013] Furthermore, in the transmission assembly, the lead screw box is also connected to a bracket on the outer wall at the end away from the second transmission pulley, and the bracket is supported on the ground.

[0014] Furthermore, a folding section is provided below the push plate, and the push plate and the folding section are integrally formed.

[0015] Preferably, the connecting assembly includes a mounting tube located at the center of the push plate, the diameter of which is larger than the diameter of the connecting tube. In addition, the connecting assembly also includes a first mounting hole on the mounting tube, a second mounting hole on the connecting tube, and a fixing bolt that corresponds to and engages with the first and second mounting holes. When the mounting tube is sleeved on the outside of the connecting tube and the first and second mounting holes correspond to each other, the connection between the push plate and the connecting tube is achieved by using the fixing bolt to engage with the first and second mounting holes.

[0016] The beneficial effects of this utility model are as follows:

[0017] In general, this utility model simplifies the design of the transmission components based on the original transmission tube drive device. It uses a lead screw, a transmission nut, and a connecting pipe to transmit the power provided by the power component. On this basis, the two transmission tubes are connected by a push plate. With the connecting component connecting the push plate and the connecting pipe, the power of the connecting pipe is simultaneously transmitted to the two transmission tubes by the push plate. This achieves the effect of providing running power to the two transmission tubes simultaneously with a single transmission component based on the lead screw. This avoids the problem that if the toothed belt on one side is damaged, the two transmission tubes will run asynchronously when two sets of transmission components drive the two transmission tubes separately.

[0018] Specifically, this utility model also provides a reinforcing component between the transmission tube and the push plate. Based on the interconnection between the transmission tube and the push plate, the two ends of the reinforcing plate are connected to the transmission tube and the push plate respectively, further forming a reinforced and stable structure to prevent the two transmission tubes from deviating in the direction of operation when driven. In addition, in the transmission component provided by this utility model, the connecting tube sleeved on the lead screw is connected to two transmission nuts to achieve stability when the connecting tube is driven by the lead screw.

[0025] This utility model provides a drive device for the transmission tubes of a ring spinning frame, applied to the yarn collection system of the ring spinning frame. The yarn collection system described in this utility model is well-known to those skilled in the art; it generally includes a yarn tube conveying mechanism, an air frame lifting mechanism, an air frame inward and outward swing mechanism, a yarn tube gripping mechanism, and a guide plate flipping mechanism. Through a control system and various sensors, these mechanisms work together to produce the final finished yarn. This utility model, considering the operating conditions of the yarn collection system in a ring spinning frame, addresses the problem of asynchronous operation of the two transmission tubes on both sides of the ring spinning frame due to damage to the toothed belt. It proposes a drive device for the transmission tubes in the yarn collection system of a ring spinning frame to solve the problem of asynchronous operation of the two transmission tubes, which can easily lead to damage to various components of the ring spinning frame.

[0026] The solution provided by this utility model will now be described in detail with reference to the accompanying drawings.

[0027] In this technical solution, such as Figure 1 As shown, a drive tube device for a ring spinning machine is applied to the collection system of the ring spinning machine. It includes drive tubes 1 located on both sides of the ring spinning machine body. The ring spinning machine body also includes a frame base plate. The drive tube device includes a power component 2, a transmission component 3, a push plate 4, and a reinforcing component 8.

[0028] Among them, such as Figures 1-2As shown, the power assembly 2 is mounted on the frame base plate via an L-shaped mounting plate 201. The power assembly 2 includes a motor, and the output end of the motor is connected to a reduction gearbox 202. The output end of the reduction gearbox 202 is provided with a first transmission pulley 203. The reduction gearbox 202 reduces the power provided by the motor and transmits it to the first transmission pulley 203. It should be noted that the frame base plate and the motor are commonly used equipment in the collection system of ring spinning machines and are existing technologies. Therefore, they will not be described in detail here and are not shown in the figure.

[0029] In this technical solution, such as Figure 2 As shown, the transmission assembly 3 includes a screw box 301 that is generally rectangular, and a screw 5 is rotatably provided inside the screw box 301. The screw 5 includes a transmission section 501 and a working section 502.

[0030] The transmission section 502 passes through the lead screw box 301 and extends to the outside of the lead screw box 301. The end of the transmission section 501 is provided with a second transmission pulley 302. The first transmission pulley 203 and the second transmission pulley 302 are connected by a transmission belt to transmit the power provided by the power assembly 2 to the lead screw 5.

[0031] In addition, such as Figure 2 As shown, the working section 502 of the lead screw 5 is located inside the lead screw box 301, and two transmission nuts 303 are threadedly connected to the outer wall of the working section 502. The two transmission nuts 303 are connected to a connecting pipe 6. The connecting pipe 6 is sleeved on the outer wall of the working section 502 and does not interfere with the working section 502. One end of the connecting pipe 6 extends from the side of the lead screw box 301 away from the second transmission pulley 302 to the outside of the lead screw box 301.

[0032] Based on the above embodiments, when the operating power provided by the power assembly 2 is transmitted to the lead screw 5 through the first transmission pulley 203, the transmission belt, and the second transmission pulley 302, the rotational motion of the lead screw 5 will be converted into linear motion of the two transmission nuts 303 and the connecting pipe 6 along the extension direction of the lead screw 5. The linear motion of the two transmission nuts 303 and the connecting pipe 6 requires not only a power source but also a corresponding limiting and guiding structure. Therefore, as... Figure 2 As shown, a set of guide rods 7 are arranged parallel to each other on both sides of the connecting pipe 6, and the two ends of the set of guide rods 7 are fixedly connected to the inner wall of the screw box 301. The two transmission nuts 303 are slidably sleeved on the outer wall of the set of guide rods 7, so as to realize the limiting and guiding function of the two transmission nuts 303 during operation.

[0033] Based on the above structure, the length of the working section 502 of the lead screw 5 is 1450mm, and the distance between the two transmission nuts 303 is 700mm. The difference between the length of the working section 502 and the distance between the two transmission nuts 303 is the distance traveled by the connecting pipe 6 in a single operation. To ensure the stability of the connecting pipe 6 during operation, in addition to connecting the connecting pipe 6 to both transmission nuts 303 simultaneously, this invention also connects a bracket 304 to the outer wall of the lead screw box 301 at the end away from the second transmission pulley 302. The bracket 304 is supported on the ground to prevent the lead screw box 301 from shaking during operation. The specific structure is as follows: Figure 1 As shown.

[0034] In this technical solution, such as Figure 1 , Figure 3 As shown, the push plate 4 is disposed between the two transmission pipes 1 and is fixedly connected to the two transmission pipes 1. In addition, the push plate 4 is also connected to the end of the connecting pipe 6 located outside the screw box 301 through the connecting assembly 9. Specifically, the connecting assembly 9 includes a mounting pipe 901 located at the middle position of the push plate 4. The diameter of the mounting pipe 901 is larger than the diameter of the connecting pipe 6. In addition, the connecting assembly 9 also includes a first mounting hole 902 on the mounting pipe 901, a second mounting hole 903 on the connecting pipe 6, and a fixing bolt 904 that corresponds to and is connected to the first mounting hole 902 and the second mounting hole 903.

[0035] In this embodiment, when the mounting tube 901 is sleeved on the outside of the connecting tube 6, and the first mounting hole 902 and the second mounting hole 903 correspond to each other, the push plate 4 is connected to the connecting tube 6 by using the cooperation of the fixing bolt 904 with the first mounting hole 902 and the second mounting hole 903. Thus, the two transmission tubes 1 can follow the movement of the connecting tube 6 with the help of the push plate 4.

[0036] Based on this, considering that the stability of the connection structure between the push plate 4 and the two transmission pipes 1 directly affects the operating efficiency and accuracy of the transmission pipes 1, this utility model also provides a reinforcing component 8 and improves the structure of the push plate 4, such as... Figure 1 , Figure 3 As shown, the reinforcing component 8 includes a set of symmetrically arranged reinforcing plates 801, wherein one end of each reinforcing plate 801 is connected to the top of the push plate 4, and the other end is connected to the two transmission pipes 1 respectively; in addition, a folding part 401 is provided below the push plate 4, and the push plate 4 and the folding part 401 are integrally formed to enhance the stability of the structure.

[0037] Specifically, this invention simplifies the design of the transmission assembly 3 based on the original transmission tube drive device. It uses a lead screw 5, a transmission nut 303, and a connecting pipe 6 to transmit the power provided by the power assembly 2. When the motor is running, the power is transmitted from the reduction gearbox 202 to the lead screw 5 through the first transmission pulley 203, the transmission belt, and the second transmission pulley 302. The rotational motion of the lead screw 5 is converted into linear motion of the two transmission nuts 303 and the connecting pipe 6 along the extension direction of the lead screw 5. Based on the connection of the push plate 4 and the connecting pipe 6 by the connecting assembly 9, the power of the connecting pipe 6 is transmitted from the push plate 4 to the two transmission tubes 1 simultaneously. This achieves the effect of providing running power to the two transmission tubes 1 simultaneously with a transmission assembly 3 based on the lead screw 5. This avoids the problem that if the toothed belt on one side is damaged, the two transmission tubes will run asynchronously when two sets of transmission assemblies drive the two transmission tubes separately.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
