Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and in particular relates to a thread feeding device for a spinning machine. Background Art

[0002] The spinning machine twists many animal and plant fibers together to spin them into threads or yarns, which can be used to weave cloth. The earliest spinning machine was very simple and was used in the 14th century. After the 18th century, people invented better spinning machines, which made the textile industry the largest industry. All spinning machines only do two things: first, they aggregate a large number of short fibers into loose cotton threads, and then they pull out the cotton threads little by little and twist them into fine cotton threads. The cotton threads become longer after twisting.

[0003] Generally, a spinning machine may get tangled when feeding in too many threads, and the threads need to be sorted out one by one, which is rather cumbersome. Therefore, a thread feeding device is needed to adjust the threads. If the thread reel is directly placed in the thread feeding device for installation and use, and the thread reel is not limited, or the pressure is too high when limiting the thread reel, the output of the thread reel will be affected, and the efficiency of the device will be reduced, and the practicability will be poor.

[0008] Preferably, a wire roller is rotatably installed in the support frame, a wire opening is provided on one side of the support frame, and an opening is provided at the bottom of the support frame.

[0010] Preferably, a plurality of auxiliary rods are fixedly installed in the two positioning plates, and the plurality of auxiliary rods all slide through the two sliding blocks.

[0011] Preferably, two fixing plates are fixedly installed on the top of the base, each of the two fixing plates has a cavity, a support bar is slidably installed in the cavity, an adjustment plate is slidably installed on the top of the fixing plate, the top end of the adjustment plate is fixedly connected to the support frame, and the bottom end of the adjustment plate is fixedly connected to the support bar.

[0012] Compared with the related art, the spinning machine thread feeding device provided by the utility model has the following beneficial effects:

[0013] Compared with the prior art, the spinning machine feeder device provided by this solution realizes the improvement of the transmission efficiency and stability of the spinning machine feeder as a whole. By controlling the extension and retraction of the electric telescopic rod, the height of the lifting plate can be adjusted to facilitate the subsequent limiting of the bobbin. When the lifting plate is raised or lowered, the pressure plate will also move up and down accordingly, thereby achieving the compression or loosening of the bobbin. This design allows the limiting mechanism to flexibly adjust the pressure on the bobbin as needed. The existence of the buffer spring, on the one hand, provides an upward support force for the pressure plate, so that the pressure plate can maintain a certain position stability; on the other hand, when the rotating seat on the pressure plate presses the bobbin, the buffer spring can play a buffering role to prevent excessive pressure from causing damage to the bobbin. The use of the rotating seat makes the subsequent bobbin rotation adjustment process smoother when outputting the line. The main function of the wire groove is to guide and fix the line drawn from the bobbin to prevent the line from being entangled or misplaced during transmission. Such a design can ensure that the line can be smoothly transmitted along the predetermined path, and improve the stability and reliability of the spinning machine's line feeding device. After that, the line is limited by the sealing plate to prevent the line from escaping from the wire groove. When the sealing plate slides to the specified position, the limit bar will be inserted into the limit groove to fix the sealing plate to prevent it from accidentally sliding or falling off. The setting of the wire roller enables the line to be more effectively guided and supported during the transmission process. The wire roller can rotate flexibly with the movement of the line, reducing the friction between the line and the support frame, thereby avoiding the wear and breakage of the line. The rotating installation of the wire roller also ensures that the line can maintain a stable tension and direction during the transmission process, and improves the working stability of the spinning machine's line feeding device. By rotating the driving motor, the bidirectional screw can be accurately controlled. When the bidirectional screw rotates, the slider will move linearly along the top of the base. This linear motion mode enables the slider to be accurately displaced in the horizontal direction. When the slider moves linearly, the connecting rod will drive the support frame to perform corresponding lifting and lowering movements. This design not only makes the lifting and lowering of the support frame more stable and reliable, but also greatly improves the convenience and flexibility of the operation of the entire device. The adjustable height of the support frame also makes the device more practical. When the support frame begins to be raised and lowered, when the support bar slides in the cavity, the adjustment plate will also move up and down, thereby providing auxiliary support for the support frame and improving the stability of the support frame.

[0022] The utility model embodiment provides a spinning machine thread feeding device, such as Figure 1-5As shown, the spinning machine feed device includes: a base 1; a support frame 2, which is arranged above the base 1; a plurality of placement seats 3, which are rotatably installed on the bottom inner wall of the support frame 2 and are used to place the bobbin; a wire guide plate 4, which is fixedly installed in the support frame 2; a plurality of electric telescopic rods 5, which are respectively fixedly installed on the outer walls on both sides of the support frame 2; a lifting plate 6, which is arranged above the support frame 2, and the output shafts of the plurality of electric telescopic rods 5 are fixedly connected to the lifting plate 6; a plurality of limiting mechanisms, which are all arranged on the lifting plate 6 and are used to limit the bobbin.

[0023] In this embodiment, by controlling the extension and retraction of the electric telescopic rod 5, the height of the lifting plate 6 can be adjusted to facilitate the subsequent limiting of the wire reel.

[0024] In a further preferred embodiment of the utility model, the limiting mechanism includes a plurality of insert rods 7, a pressure plate 8, a plurality of buffer springs 9 and a rotating seat 10, the plurality of insert rods 7 are slidably mounted on the top of the lifting plate 6, the pressure plate 8 is arranged below the lifting plate 6, the bottom ends of the plurality of insert rods 7 are fixedly connected to the pressure plate 8, the plurality of buffer springs 9 are respectively sleeved on the plurality of insert rods 7, the two ends of the plurality of buffer springs 9 are respectively fixedly connected to the bottom of the lifting plate 6 and the top of the pressure plate 8, the rotating seat 10 is rotatably mounted on the bottom of the pressure plate 8, and the rotating seat 10 is arranged corresponding to the placement seat 3.

[0025] In this embodiment, when the lifting plate 6 is lifted or lowered, the pressing plate 8 will also move up and down accordingly, thereby achieving the compression or loosening of the wire reel. This design allows the limit mechanism to flexibly adjust the pressure on the wire reel as needed. The existence of the buffer spring 9, on the one hand, provides an upward support force for the pressing plate 8, so that the pressing plate 8 can maintain a certain position stability; on the other hand, when the rotating seat 10 on the pressing plate 8 presses the wire reel, the buffer spring 9 can play a buffering role to prevent excessive pressure from causing damage to the wire reel. The use of the rotating seat 10 makes the subsequent rotation adjustment process smoother when the wire reel is output.

[0026] In a further preferred embodiment of the utility model, a plurality of wire grooves 11 are provided on the wire plate 4, a sealing plate 12 is slidably installed on the top of the wire plate 4, two limit grooves 13 are provided on the top of the wire plate 4, and two limit strips 14 are fixedly installed on the bottom of the sealing plate 12, and the two limit strips 14 are respectively adapted to the two limit grooves 13.

Such a design can ensure that the wire can be smoothly transmitted along the predetermined path, improve the stability and reliability of the spinning machine's wire feeding device, and then the wire is limited by the sealing plate 12 to prevent the wire from escaping from the wire groove 11. When the sealing plate 12 slides to the specified position, the limiting strip 14 will be inserted into the limiting groove 13, thereby fixing the sealing plate 12 to prevent it from accidentally sliding or falling off.

[0029] In this embodiment, the arrangement of the wire roller 15 enables the wire to be more effectively guided and supported during the transmission process. The wire roller 15 can rotate flexibly with the movement of the wire, reducing the friction between the wire and the support frame 2, thereby avoiding the wear and breakage of the wire. At the same time, the rotating installation of the wire roller 15 also ensures that the wire can maintain a stable tension and direction during the transmission process, thereby improving the working stability of the spinning machine feed device.

[0030] In a further preferred embodiment of the utility model, two symmetrically arranged positioning plates are fixedly installed on the top of the base 1, and bidirectional screws 16 are rotatably installed in the two positioning plates. A driving motor 17 is fixedly installed on the top of the base 1, and the output shaft of the driving motor 17 is fixedly connected to one end of the bidirectional screw 16. Two sliders 18 are slidably installed on the top of the base 1, and both of the sliders 18 are threadedly connected to the bidirectional screw 16. Multiple connecting rods 19 are hingedly installed on the two sliders 18, and the top ends of the multiple connecting rods 19 are fixedly connected to the bottom of the support frame 2.

[0031] In this embodiment, the bidirectional screw 16 can be precisely controlled by the rotation of the driving motor 17. When the bidirectional screw 16 rotates, the slider 18 will move linearly along the top of the base 1. This linear motion enables the slider 18 to move accurately in the horizontal direction. When the slider 18 moves linearly, the connecting rod 19 drives the support frame 2 to perform corresponding lifting and lowering movements. This design not only makes the lifting and lowering of the support frame 2 more stable and reliable, but also greatly improves the convenience and flexibility of the operation of the entire device. The adjustable height of the support frame 2 also makes the device more practical.

[0032] In a further preferred embodiment of the present invention, a plurality of auxiliary rods 20 are fixedly installed in the two positioning plates, and the plurality of auxiliary rods 20 all slide through the two sliding blocks 18 .

[0035] In this embodiment, when the support frame 2 begins to be raised and lowered, when the support bar 22 slides in the cavity, the adjustment plate 23 will also be raised and lowered, thereby providing auxiliary support to the support frame 2 and improving the stability of the support frame 2.

[0036] In summary, compared with the relevant technology, the present device has achieved the improvement of the transmission efficiency and stability of the incoming line of the spinning machine as a whole. By controlling the extension and retraction of the electric telescopic rod 5, the height of the lifting plate 6 can be adjusted to facilitate the subsequent limiting of the bobbin. When the lifting plate 6 is lifted or lowered, the pressing plate 8 will also move up and down accordingly, thereby achieving the compression or loosening of the bobbin. This design allows the limiting mechanism to flexibly adjust the pressure on the bobbin as needed. The existence of the buffer spring 9, on the one hand, provides an upward support force for the pressing plate 8, so that the pressing plate 8 can maintain a certain position stability; on the other hand, when the rotating seat 10 on the pressing plate 8 presses the bobbin, the buffer spring 9 can play a buffering role to prevent the bobbin from being damaged by excessive pressure. The use of the rotating seat 10 makes the subsequent bobbin rotate and adjust the process more smoothly when outputting the line. The main function of the wire groove 11 is to guide and fix the line drawn from the bobbin to prevent the line from being entangled or misplaced during transmission. Such a design can ensure that the wire can be smoothly transmitted along the predetermined path, thereby improving the stability and reliability of the spinning machine's wire feeding device. The wire is then limited by the sealing plate 12 to prevent the wire from escaping from the wire groove 11. When the sealing plate 12 slides to the specified position, the limiting strip 14 will be inserted into the limiting groove 13, thereby fixing the sealing plate 12 to prevent it from accidentally sliding or falling off. The setting of the wire roller 15 enables the wire to be more effectively guided and supported during the transmission process. The wire roller 15 can rotate flexibly with the movement of the wire, reducing the friction between the wire and the support frame 2, thereby avoiding the wear and breakage of the wire. The rotating installation of the wire roller 15 also ensures that the wire can maintain stable tension and direction during the transmission process, and improves the working stability of the spinning machine feeding device. Through the rotation of the driving motor 17, the precise control of the bidirectional screw 16 can be achieved. When the bidirectional screw 16 rotates, the slider 18 will move linearly along the top of the base 1. This linear motion mode enables the slider 18 to be accurately displaced in the horizontal direction. When the slider 18 moves linearly, the connecting rod 19 will drive the support frame 2 to perform corresponding lifting and lowering movements. This design not only makes the lifting and lowering of the support frame 2 more stable and reliable, but also greatly improves the convenience and flexibility of the operation of the entire device. The adjustable height of the support frame 2 also makes the device more practical. When the support frame 2 starts to be lifted and lowered, when the support bar 22 slides in the cavity, the adjustment plate 23 will move up and down accordingly, thereby providing auxiliary support to the support frame 2 and improving the stability of the support frame 2.
