Technical Field
[0001] The utility model relates to the technical field of knitting flat knitting machines, in particular to a yarn guiding device for a knitting flat knitting machine. Background Art
[0002] A knitting flat knitting machine is a mechanical device for producing knitted products. It weaves yarn into fabric through a series of complex mechanical actions. The needle beds of the flat knitting machine are usually arranged horizontally and there are two needle beds, located at the front and rear of the machine respectively. Tongue needles are installed on the needle beds. This design allows the flat knitting machine to form a continuous knitted structure during the knitting process and can knit flat or three-dimensional garment pieces and other products, such as clothes, scarves, hats, etc. The yarn guiding device is a key component in the knitting flat knitting machine, responsible for guiding the yarn from the yarn bobbin to the knitting needles to ensure that the yarn is correctly wound around the knitting needles, thus realizing the knitting process.
[0003] However, the functionality of the existing yarn guiding devices of knitting flat knitting machines is relatively single. During the use process, the operator needs to often pause the machine to adjust the yarn because the tension of the yarn changes with the reciprocating movement of the machine head, resulting in the tension being sometimes large and sometimes small. It is very difficult for the yarn guiding device to accurately control the tightness of the yarn, causing the yarn to easily slip or be overstretched. The yarn is prone to deviate from the correct position during the transmission process, resulting in inaccurate yarn guiding, increasing the complexity of the operation, and reducing the stability of the knitting process and the product quality. Therefore, a new type of yarn guiding device for a knitting flat knitting machine needs to be proposed. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems that the tension of the yarn changes with the reciprocating movement of the machine head, resulting in the tension being sometimes large and sometimes small, causing the yarn to easily slip or be overstretched, and the yarn is prone to deviate from the correct position during the transmission process, resulting in inaccurate yarn guiding, and to propose a yarn guiding device for a knitting flat knitting machine.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A yarn guiding device for a knitting flat knitting machine, including an operation table. One side of the top wall of the operation table is provided with a knitting machine body. One side of the surface of the knitting machine body is fixedly connected with a bearing. One side of the top wall of the operation table is fixedly connected with a working box. One side of the inner wall of the working box is provided with a first motor. One side of the surface of the first motor is provided with an adjusting plate. Two rotating shafts are fixedly connected to the surface of the adjusting plate. One of the rotating shafts is rotatably connected with the bearing, and the other rotating shaft is connected with the first motor. One side of the surface of the adjusting plate is hinged with a clamping plate. One side of the surface of the clamping plate is fixedly connected with a protective pad. One side of the top wall of the working box is provided with a tension sensor.
[0006] Preferably, one side of the top wall of the operation table is fixedly connected with a bracket, and two support plates are fixedly connected to one side of the top wall of the bracket.
[0007] Preferably, a lead screw is rotatably connected to one side of the outer walls of the two support plates, and a second motor is installed on one side of the outer wall of the lead screw.
[0008] Preferably, two first sliding grooves are formed in one side of the top wall of the bracket, a slider is threadedly connected to one side of the outer wall of the lead screw, and the slider is slidably connected to the two first sliding grooves.
[0009] Preferably, a machine head is fixedly connected to one side of the bottom wall of the slider, and a second sliding groove is formed in one side of the top wall of the machine head.
[0010] Preferably, a wire threading plate is slidably connected to one side of the top wall of the second sliding groove, and a connecting plate is fixedly connected to one side of the outer wall of the wire threading plate.
[0011] Preferably, an electric push rod is installed on one side of the outer wall of the connecting plate, and a deviation rectifying sensor is installed on one side of the bottom wall of the machine head.
[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.
[0013] 1. In the present utility model, under the action of the tension sensor, it is detected that the tension of the yarn changes. The first motor is started through the control system. The output end of the first motor rotates to drive the clamping plate to rotate, and then drives the yarn to move around the adjusting plate, thereby reasonably adjusting the tension of the yarn, improving the working efficiency of the thread picking device, reducing the working intensity of the user, and enhancing the stability of the knitting process and the product quality.
[0014] 2. In the present utility model, under the action of the deviation rectifying sensor, it is detected that the yarn deviates. The electric push rod is started through the control system. Under the action of the electric push rod, the wire threading plate is driven to move.

[0023] In this embodiment, the user winds one end of the yarn around the knitting machine body 2, passes a part of the yarn through the adjusting plate 3, then rotates the clamping plate 4 to restrict the yarn, and protects the yarn under the action of the protection pad 5. Then, when the tension sensor 9 detects a problem with the tension of the yarn (the model of the tension sensor 9 is KOSD-0313-60KN), the first motor 10 installed inside the working box 8 is started through the control system. The first motor 10 is a belt motor. The output end of the first motor 10 rotates to drive the driving pulley to rotate. The driving pulley rotates to drive the belt to rotate. The belt rotates to drive the driven pulley to rotate. The driven pulley rotates to drive the rotating shaft 7 on one side to rotate. Under the action of the bearing 6, the two rotating shafts 7 rotate to drive the adjusting plate 3 to rotate, thereby driving the yarn to move around the adjusting plate 3, so as to reasonably adjust the tension of the yarn, improve the working efficiency of the thread picking device, reduce the working intensity of the user, and enhance the stability of the knitting process and the product quality. The operating table 1 plays a supporting role for the knitting machine body 2.
[0024] Embodiment 2: As Figures 1 - 4 shown, one side of the top wall of the operating table 1 is fixedly connected with a bracket 11. One side of the top wall of the bracket 11 is fixedly connected with two support plates 22. One side of the surface of the two support plates 22 is rotatably connected with a lead screw 14. One side of the surface of the lead screw 14 is provided with a second motor 15. Two first chutes 13 are opened on one side of the top wall of the bracket 11. One side of the surface of the lead screw 14 is threadedly connected with a slider 12. The slider 12 is slidably connected with the two first chutes 13. One side of the bottom wall of the slider 12 is fixedly connected with a machine head 16. A second chute 19 is opened on one side of the top wall of the machine head 16. One side of the top wall of the second chute 19 is slidably connected with a thread threading plate 18. One side of the surface of the thread threading plate 18 is fixedly connected with a connecting plate 21. One side of the surface of the connecting plate 21 is provided with an electric push rod 20. One side of the bottom wall of the machine head 16 is provided with a deviation correction sensor 17.
[0025] In this embodiment, the user starts the second motor 15 installed on the bracket 11. Under the action of the second motor 15, the output end of the second motor 15 rotates to drive the lead screw 14 to rotate. The lead screw 14 rotates to drive the slider 12 to move on the two first chutes 13. The two support plates 22 play a supporting role for the lead screw 14. The slider 12 moves to drive the machine head 16 to move, thereby improving the working efficiency of the thread picking device. Then, under the action of the deviation correction sensor 17 (the model of the deviation correction sensor 17 is SS-RP infrared sensor), it is detected that the yarn is deflected. The electric push rod 20 is started through the control system. The output end of the electric push rod 20 moves to drive the connecting plate 21 to move. The connecting plate 21 moves to drive the thread threading plate 18 to slide inside the second chute 19, thereby driving the yarn to move, avoiding the extra friction generated when the yarn goes off track, reducing the waste of raw materials, saving costs, ensuring that the yarn always stays in the correct position during the knitting process, and avoiding deviating from the track.
[0026] Working principle of this embodiment: When in use, first connect the power supply. The user winds one end of the yarn around the knitting machine body 2, passes a part of the yarn through the adjusting plate 3, then rotates the clamping plate 4 to restrict the yarn, and protects the yarn under the action of the protective pad 5. Then, when the tension sensor 9 detects a problem with the yarn tension, the first motor 10 is started through the control system. The first motor 10 is a belt motor. The output end of the first motor 10 rotates to drive the rotation of the rotating shaft 7 on one side. Under the action of the bearing 6, the two rotating shafts 7 rotate to drive the rotation of the adjusting plate 3, thereby driving the yarn to move around the adjusting plate 3, so as to reasonably adjust the tension of the yarn. Then, the user starts the second motor 15. The output end of the second motor 15 rotates to drive the rotation of the lead screw 14. The lead screw 14 rotates to drive the slider 12 to move on the two first chutes 13. The movement of the slider 12 drives the movement of the machine head 16, thereby improving the working efficiency of the thread picking device. Finally, under the action of the deviation correction sensor 17, when it detects that the yarn is deviated, the electric push rod 20 is started through the control system. The output end of the electric push rod 20 moves to drive the movement of the connecting plate 21. The movement of the connecting plate 21 drives the threading plate 18 to slide inside the second chute 19, thereby driving the movement of the yarn and avoiding the additional friction generated when the yarn goes off track.
