Description

Technical Field

[0001] The utility model relates to the technical field of knitting, in particular to a yarn tension control device for double-layer seamless knitted fabrics. Background Technique

[0002] Knitting refers to the process of using knitting needles to form coils of various raw materials and varieties of yarns, and then connecting them into knitted fabrics through stringing. Knitted fabrics are soft in texture, have good wrinkle resistance and air permeability, and have relatively large extensibility and elasticity, making them comfortable to wear. In addition to being used for clothing and decoration, knitted products can also be used in industries, agriculture, medical and health, national defense and other fields.

[0003] Double-layer seamless knitted fabric is a high-quality fabric that combines the advantages of double-layer knitted fabric and seamless knitting technology. During the production and processing of double-layer seamless knitted fabric, a tension control device will be installed on the yarn movement and conveying line to control the tension of the yarn.

[0004] Patent Publication No. CN219906531U discloses a yarn tension control device for winding yarn and controlling the tension of the yarn, including a bottom plate and an oil tank. The bottom plate is divided into a first working surface and a second working surface. The first working surface is provided with a driving wheel, a plurality of driven wheels and a plurality of tension wheels fixed on the first working surface by shafts and bearings. The driving wheel is installed at one end of the driving wheel shaft. The second working surface is provided with a hydraulic pump, and the hydraulic pump is connected to the other end of the driving wheel shaft by a coupling. The oil tank is respectively connected to the oil inlet and oil outlet of the hydraulic pump through an oil inlet pipe and an oil outlet pipe. This utility model uses a hydraulic pump to adjust the torque of the driving wheel, thereby realizing the adjustment of the yarn tension control device. It can not only achieve precise tension adjustment through a pressure gauge and a pressure regulating valve, but also save costs and energy.

[0005] The deficiencies of the existing yarn tension control device are as follows: By adjusting the torque of the driving wheel through a hydraulic pump to realize the adjustment of the yarn tension control device, the yarn will rotate outside the driving wheel, and it is impossible to ensure that the torque of the driving wheel can adjust the yarn tension. Therefore, a yarn tension control device for double-layer seamless knitted fabric is proposed. By driving a lead screw to rotate through a servo motor, the internal thread slider and the tension sensor are pushed upward, thereby pulling the yarn, and its tension can be adjusted. Content of the Utility Model

[0006] Aiming at the problems in the prior art, the utility model provides a yarn tension control device for double-layer seamless knitted fabric. By driving a lead screw to rotate through a servo motor, the internal thread slider and the tension sensor are pushed upward, thereby pulling the yarn, and its tension can be adjusted.

[0007] The technical solution adopted by the present utility model to solve its technical problems is a yarn tension control device for double-layer seamless knitted fabrics, including a main board and a tension controller. A control component is fixed on one side of the main board. The control component includes a box body fixed to one side of the main board by bolts. A servo motor is installed at the bottom of the box body through a mounting bracket. A lead screw is rotatably connected inside the box body through a bearing. An internally threaded slider is sleeved outside the lead screw. Both ends of the top of the internally threaded slider are connected with connecting rods through threaded grooves. The top ends of the connecting rods are installed with tension sensors through mounting brackets.

[0008] Moving components are arranged at both ends of the main board. The moving components include board sleeves sleeved on both ends of the main board. A connecting plate is welded on one side of the board sleeve. An auxiliary wheel is rotatably connected to one side of the connecting plate through a shaft rod.

[0009] By adopting the above technical solution, the servo motor drives the control component to rotate, pushes the internally threaded slider to move up and down. The movement of the internally threaded slider drives the tension sensor to move up and down through the connecting rod, pulling the yarn to adjust its tension.

[0010] Specifically, limiting slide bars are welded at both ends inside the box body. Limiting grooves are opened at both ends of the internally threaded slider. The limiting grooves are sleeved outside the limiting slide bars.

[0011] Specifically, the output shaft at the top of the servo motor is fixedly connected to the bottom end of the lead screw through a connecting sleeve.

[0012] Specifically, clamping grooves are opened at both ends on one side of the main board. A fixing bolt corresponding to the clamping groove is connected to one side of the board sleeve through a threaded groove.

[0013] Specifically, the current output end of the tension controller is electrically connected to the current input end of the tension sensor through a power cord.

[0014] Specifically, limiting blocks are welded at both ends of the main board.

[0015] The beneficial effects of the present utility model:

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] By driving the lead screw to rotate through the servo motor, the internally threaded slider and the tension sensor are pushed to move upward, thereby pulling the yarn, and its tension can be adjusted. As Figures 1-3 shown, a yarn tension control device for a double-layer seamless knitted fabric described in the present utility model includes a main board 1 and a tension controller 3. A control component 2 is fixed on one side of the main board 1. The control component 2 includes a box body 201 fixed to one side of the main board 1 by bolts. A servo motor 204 is installed at the bottom of the box body 201 through a mounting bracket. A lead screw 202 is rotatably connected inside the box body 201 through a bearing. An internally threaded slider 203 is sleeved outside the lead screw 202. Both ends of the top of the internally threaded slider 203 are connected with a connecting rod 205 through a threaded groove. The top of the connecting rod 205 is installed with a tension sensor 4 through a mounting bracket;

[0026] Moving components 5 are arranged at both ends of the main board 1. The moving components 5 include plate sleeves 501 sleeved at both ends of the main board 1. A connecting plate 502 is welded on one side of the plate sleeve 501. An auxiliary wheel 7 is rotatably connected to one side of the connecting plate 502 through a shaft rod.

[0027] During use, the servo motor 204 drives the control assembly 2 to rotate, pushing the internally threaded slider 203 to move up and down. The movement of the internally threaded slider 203 drives the servo motor 204 to move up and down through the connecting rod 205, pulling the yarn to adjust its tension.

[0028] Exemplarily, as Figure 2 shown, the present invention further includes that both ends inside the box body 201 are welded with limit slide bars 206. Limit slots 207 are opened at both ends of the internally threaded slider 203, and the limit slots 207 are sleeved outside the limit slide bars 206.

[0029] During use, the limit slide bars 206 and the limit slots 207 can limit the internally threaded slider 203 while not affecting its up and down movement, preventing the internally threaded slider 203 from skewing.

[0030] Exemplarily, as Figure 2 shown, the present invention further includes that the top output shaft of the servo motor 204 is fixedly connected to the bottom end of the lead screw 202 through a connecting sleeve.

[0031] During use, the servo motor 204 is used to drive the lead screw 202 to rotate.

[0032] Exemplarily, as Figure 1 、 Figure 3 shown, the present invention further includes that both ends of one side of the main board 1 are provided with card slots 6, and one side of the board sleeve 501 is connected with fixing bolts 503 corresponding to the card slots 6 through threaded grooves.

[0033] During use, by tightening the fixing bolts 503 so that one end of each of them inserts into the corresponding card slot 6, the moved board sleeve 501 can be fixed.

[0034] Exemplarily, as Figure 1 shown, the present invention further includes that the current output end of the tension controller 3 is electrically connected to the current input end of the tension sensor 4 through a power line.

[0035] During use, the data detected by the tension sensor 4 is transmitted to the tension controller 3 for processing and display.

[0036] Exemplarily, as Figure 1 shown, the present invention further includes that both ends of the main board 1 are welded with limit blocks 8.

[0037] During use, the limit blocks 8 can prevent the board sleeve 501 from falling off the main board 1.

[0038] When the utility model is in use, a person installs the main board 1 on the yarn conveying line, connects the device to an external power supply using a power cord, winds the yarn around the detection wheel of the tension sensor 4, and places the two ends of the yarn at the bottom of the auxiliary wheel 7; when the yarn moves, it drives the auxiliary wheel 7 and the detection wheel of the tension sensor 4 to rotate, and the auxiliary wheel 7 is used to limit the position of the yarn;

[0039] When the yarn moves, the detection wheel of the tension sensor 4 rotates, which can detect the current tension of the yarn and transmit the data to the tension controller 3 for processing and display;

[0040] The servo motor 204 operates to drive the lead screw 202 to rotate, pushing the internally threaded slider 203 to move up and down. The up and down movement of the internally threaded slider 203 pushes the tension sensor 4 to move up and down through the connecting rod 205. When the tension sensor 4 moves up and down, the distance between its detection wheel and the auxiliary wheel 7 changes, thereby pulling the yarn to facilitate the adjustment of the yarn tension;

[0041] The moving plate sleeve 501 drives the auxiliary wheel 7 to move through the connecting plate 502, and the position of the auxiliary wheel 7 can be adjusted. Tighten the fixing bolt 503 so that one end of it inserts into the corresponding card slot 6 to fix the moved plate sleeve 501.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present utility model.
