Description

Technical Field

[0001] The utility model relates to the technical field of doubling twisting machines, in particular to a yarn guiding device for a borderless doubling twisting machine. Background Art

[0002] A doubling twisting machine is a kind of textile machinery, mainly used for twisting multiple yarns into one or more strands of yarn. It realizes the twisting process through a series of mechanical components and electronic control systems. Its product structure includes a main machine, a motor, a transmission system, a yarn guiding device, a doubling twisting bobbin, a tensioner, a heating system, etc.

[0003] However, when the existing yarn guiding device of the borderless doubling twisting machine is in use, the yarn guiding wheel for guiding yarn inside the borderless doubling twisting machine is usually fixed. When adjusting the yarn tension, it is necessary for the staff to manually adjust it, and the operation steps are cumbersome. At the same time, when the yarn is guided and conveyed inside the borderless doubling twisting machine, the yarn will rub against the accessories of the borderless doubling twisting machine, and the friction will cause the yarn to generate static electricity, making the waste silk adsorbed on the surface of the yarn, which has a certain impact on the stability and quality of yarn production. Therefore, a yarn guiding device for a borderless doubling twisting machine is provided. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a yarn guiding device for a borderless doubling twisting machine. By setting a fixed frame, a servo motor, a coupling, a lead screw, a support plate, an ion fan, a transmission sleeve and a fixing plate, the utility model solves the problems that when the existing yarn guiding device of the borderless doubling twisting machine is in use, it is inconvenient to adjust the tension of the yarn inside the frame of the borderless doubling twisting machine, and it is also inconvenient to remove static electricity from the yarn.

[0005] The technical solution adopted by the utility model to solve its technical problems is a yarn guiding device for a borderless doubling twisting machine, including a frame of the borderless doubling twisting machine. A driving frame is slidably connected to the inner side of the frame of the borderless doubling twisting machine, and a yarn guiding wheel A for guiding the yarn is rotatably connected to the inner side of the driving frame. A driving component for driving the driving frame to move is arranged at the bottom of the frame of the borderless doubling twisting machine. The driving component includes a fixed frame, a servo motor, a coupling, a lead screw, a transmission sleeve and a fixing plate. A fixed frame is welded below the frame of the borderless doubling twisting machine, and a servo motor providing power is bolted to the inner side of the fixed frame. The power output end of the servo motor is key-connected with a coupling, and a lead screw is key-connected to the inner side of the coupling. A transmission sleeve is threadedly connected to the outside of the lead screw, and a fixing plate connected to the driving frame is welded to the outside of the transmission sleeve. A support plate is welded to the outside of the driving frame, and an ion fan for eliminating static electricity of the yarn is screwed to one side of the support plate. A bearing seat for making the lead screw rotate stably is screwed to the bottom of the frame of the borderless doubling twisting machine.

[0006] By adopting the above technical solution, when the yarn on the frame of the endless twister is guided by the yarn guide wheel A in the drive frame, the external controller turns on the servo motor switch in the fixed frame. The servo motor converts the received electrical energy into mechanical energy. The coupling on the servo motor drives the lead screw to rotate. The lead screw rotates through the bearing block at the bottom of the endless twister frame. Subsequently, the transmission sleeve outside the lead screw drives the fixed plate to move, and the fixed plate drives the drive frame to move, so that the guide wheel A on the drive frame moves within the endless twister frame, thereby facilitating the adjustment of the tension of the yarn in the endless twister frame;

[0007] When the yarn guide wheel A guides the yarn, the external controller turns on the ion fan switch on the external support plate of the drive frame. The ion fan inhales air and ionizes the molecules or atoms in the air through the ionizer built in the ion fan to generate positive and negative ions. The generated positive and negative ions will react with the static charges on the yarn. The positive and negative ions will adhere to the static charges to neutralize their charging properties. At the same time, it speeds up the air flow speed on the surface of the yarn, thereby facilitating the anti-static operation of the yarn conveyed in the endless twister frame and facilitating the cleaning of the waste filaments adhered to the yarn.

[0008] Specifically, a chute is provided on one side of the endless twister frame, and a slider connected to the drive frame is slidably connected inside the chute.

[0009] By adopting the above technical solution, when the fixed plate drives the drive frame to move, the slider outside the drive frame slides in the chute provided on the endless twister frame, improving the stability of the drive frame moving on the endless twister frame.

[0010] Specifically, a yarn guide wheel B and a yarn guide wheel C for guiding the yarn are rotatably connected inside the endless twister frame, and the yarn guide wheel B is located on the left side of the yarn guide wheel C.

[0011] By adopting the above technical solution, the yarn guide wheel B and the yarn guide wheel C in the endless twister frame perform yarn guiding treatment.

[0012] Specifically, a vertical rod is welded inside the fixed frame, and a support block connected to the transmission sleeve is slidably connected outside the vertical rod.

[0013] By adopting the above technical solution, when the lead screw drives the transmission sleeve to move, the support block outside the transmission sleeve slides outside the vertical rod, thereby facilitating the limiting treatment of the transmission sleeve.

[0014] Specifically, the input ends of the ion fan and the servo motor are electrically connected to the power supply end of the external power supply.

[0015] By adopting the above technical solution, by connecting to the external power supply, the electrical equipment works normally.

[0016] The beneficial effects of the present utility model:

[0017] (1) A yarn guiding device for a borderless doubling twisting machine according to the present utility model. When the yarn on the frame of the borderless doubling twisting machine is guided by the yarn guiding wheel A in the driving frame, the external controller turns on the servo motor switch in the fixing frame. The servo motor converts the received electrical energy into mechanical energy. The coupling on the servo motor drives the lead screw to rotate. The lead screw rotates through the bearing seat at the bottom of the frame of the borderless doubling twisting machine. Subsequently, the transmission sleeve outside the lead screw drives the fixing plate to move, and the fixing plate drives the driving frame to move, so that the guiding wheel A on the driving frame moves within the frame of the borderless doubling twisting machine, thereby facilitating the adjustment of the tension of the yarn within the frame of the borderless doubling twisting machine.

[0018] (2) A yarn guiding device for a borderless doubling twisting machine according to the present utility model. When the yarn guiding wheel A guides the yarn, the external controller turns on the ion fan switch on the external support plate of the driving frame. The ion fan inhales air and ionizes the molecules or atoms in the air through the ionizer built in the ion fan to generate positive and negative ions. The generated positive and negative ions will react with the static charges on the yarn. The positive and negative ions will adhere to the static charges to neutralize their charging properties.

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0024] In order to adjust the tension of the yarn within the frame 3 of the borderless doubling twisting machine, as an embodiment of the present utility model, such as Figure 1 、 Figure 2As shown, a yarn guiding device of an endless two-for-one twisting machine described in the utility model comprises an endless two-for-one twisting machine frame 3, a driving frame 8 is slidably connected to the inner side of the endless two-for-one twisting machine frame 3, and a yarn guide wheel A2 for guiding the yarn is rotatably connected to the inner side of the driving frame 8, a driving assembly 10 for driving the driving frame 8 to move is arranged at the bottom of the endless two-for-one twisting machine frame 3, and the driving assembly 10 comprises a fixed frame 18, a servo motor 12, a coupling 19, a screw rod 15, a transmission sleeve 14 and a fixed plate 11, and a fixed frame 18 is welded below the endless two-for-one twisting machine frame 3, and a fixed frame 18 is fixed to the bottom of the endless two-for-one twisting machine frame 3. A servo motor 12 for providing power is bolted to the inner side of the fixed frame 18, a coupling 19 is keyed to the power output end of the servo motor 12, and a lead screw 15 is keyed to the inner side of the coupling 19, a transmission sleeve 14 is threadedly connected to the outer side of the lead screw 15, and a fixing plate 11 connected to a driving frame 8 is welded to the outer side of the transmission sleeve 14, a support plate 6 is welded to the outer side of the driving frame 8, an ion fan 1 for eliminating static electricity on the yarn is screwed to one side of the support plate 6, and a bearing seat 13 for stably rotating the lead screw 15 is screwed to the bottom of the frame 3 of the endless two-for-one twisting machine.

[0025] When in use, when the yarn on the endless two-for-one twister frame 3 is guided in the yarn guide wheel A2 in the driving frame 8, the external controller turns on the switch of the servo motor 12 in the fixed frame 18, and the servo motor 12 converts the received electrical energy into mechanical energy. The coupling 19 on the servo motor 12 drives the screw rod 15 to rotate, and the screw rod 15 rotates through the bearing seat 13 at the bottom of the endless two-for-one twister frame 3. Then the transmission sleeve 14 outside the screw rod 15 drives the fixed plate 11 to move, and the fixed plate 11 drives the driving frame 8 to move, so that the guide wheel A on the driving frame 8 moves in the endless two-for-one twister frame 3, so as to facilitate the adjustment of the tension of the yarn in the endless two-for-one twister frame 3;

[0026] When the yarn guide wheel A2 guides the yarn, the external controller turns on the switch of the ion fan 1 on the external support plate 6 of the drive frame 8, and the ion fan 1 draws in air. The molecules or atoms in the air are ionized into positive and negative ions through the built-in ionizer of the ion fan 1. The generated positive and negative ions will react with the electrostatic charge on the yarn. The positive and negative ions will attach to the electrostatic charge to neutralize its charged properties and accelerate the air flow speed on the surface of the yarn, thereby facilitating the static electricity removal operation of the yarn transported in the endless two-for-one twisting machine frame 3 and cleaning the waste silk adhering to the yarn.

[0027] In order to improve the stability of the driving frame 8 moving on the endless two-for-one twisting machine frame 3, for example, Figure 1 As shown, the utility model also includes that a slide groove 5 is opened on one side of the frame 3 of the endless two-for-one twisting machine, and a slider 7 connected to a driving frame 8 is slidably connected inside the slide groove 5.

[0028] When in use, when the fixed plate 11 drives the driving frame 8 to move, the slider 7 outside the driving frame 8 slides in the slide groove 5 provided on the endless two-for-one twister frame 3, thereby improving the stability of the driving frame 8 moving on the endless two-for-one twister frame 3.

[0030] When in use, the yarn guide wheel B4 and the yarn guide wheel C9 in the frame 3 of the endless two-for-one twisting machine guide the yarn.

[0033] In order to use the electrical equipment to work normally, for example, Figure 1 , Figure 2 As shown, the utility model also includes that the input ends of the ion fan 1 and the servo motor 12 are both electrically connected to the power supply end of the external power supply.

[0034] When in use, by connecting to an external power source, the electrical equipment can work normally.

[0035] When the utility model is in use, when the yarn on the endless two-for-one twister frame 3 is guided in the yarn guide wheel A2 in the driving frame 8, the external controller turns on the switch of the servo motor 12 in the fixed frame 18, and the servo motor 12 converts the received electrical energy into mechanical energy. The coupling 19 on the servo motor 12 drives the screw rod 15 to rotate, and the screw rod 15 rotates through the bearing seat 13 at the bottom of the endless two-for-one twister frame 3. Then the transmission sleeve 14 outside the screw rod 15 drives the fixed plate 11 to move, and the fixed plate 11 drives the driving frame 8 to move, so that the guide wheel A on the driving frame 8 moves in the endless two-for-one twister frame 3, so as to facilitate the adjustment of the tension of the yarn in the endless two-for-one twister frame 3;

[0036] When the yarn guide wheel A2 guides the yarn, the external controller turns on the switch of the ion fan 1 on the outer support plate 6 of the driving frame 8. The ion fan 1 sucks in air, and through the ionizer built in the ion fan 1, the molecules or atoms in the air are ionized into positive and negative ions. The generated positive and negative ions will react with the static charges on the yarn. The positive and negative ions will attach to the static charges, neutralizing their charged properties. At the same time, the air flow speed on the surface of the yarn is increased, thus facilitating the anti-static operation of the yarn conveyed in the endless doubling frame 3 and facilitating the cleaning of the waste filaments adhered to the yarn.

[0037] When the fixed plate 11 drives the driving frame 8 to move, the slider 7 outside the driving frame 8 slides in the chute 5 opened on the endless doubling frame 3, improving the stability of the driving frame 8 moving on the endless doubling frame 3.

[0038] The yarn guide wheel B4 and the yarn guide wheel C9 in the endless doubling frame 3 conduct yarn guiding treatment.
