Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a thread feeding device for a sock-shaping machine. Background Technology

[0002] In the textile production process, testing the dyeing and printing performance of yarn is a key step in ensuring the quality of finished products. Currently, the industry generally uses a sock-making machine to weave yarn into sock bands, and then cuts the sock bands for dyeing and printing experiments to determine the dyeing and printing performance of products woven from the yarn.

[0003] In operation, existing sock-rolling machines place yarn spools on a simple support and feed yarn through a combination of a yarn feed wheel and a guide wheel. A pulley system is used to assist in the yarn feeding process. The rolling of the pulleys reduces the friction between the yarn and the device, thus meeting the basic requirements of yarn feeding in sock-rolling machines and providing support for sock production. Regarding the aforementioned technologies, when there is a lot of yarn on the yarn bobbin, the yarn bobbin can easily obstruct the yarn delivery, resulting in poor smoothness during the yarn feeding process. Furthermore, under the combined action of the yarn bobbin and the yarn feeding wheel, the yarn is easily torn apart. When there is less yarn on the yarn bobbin, when the yarn feeding wheel pulls the yarn, the yarn bobbin is easily tilted due to the yarn's movement, resulting in poor stability of the yarn feeding device. Utility Model Content

[0004] In order to improve the stability of the thread feeding device of the sock shaking machine, this application provides a thread feeding device for the sock shaking machine.

[0005] This application provides a thread feeding device for a sock-shaping machine, which adopts the following technical solution: A yarn feeding device for a sock-shaping machine includes a processing table. A connecting block is provided at the upper end of the processing table. The connecting block has a groove, and a yarn spool is placed in the groove and engaged with the inner wall of the groove. A sliding rod is provided on one side of the connecting block, slidingly connected to the connecting block laterally. The sliding rod passes through the yarn spool and engages with the inner wall of the connecting block. A motor is fixedly mounted at the upper end of the processing table, and the output shaft of the motor is coaxially fixed with the connecting block. A yarn feeding assembly is provided on one side of the connecting block, and a processing assembly is provided on one side of the yarn feeding assembly. The yarn feeding assembly smoothly feeds the yarn to the processing assembly, which then processes the yarn.

[0006] By adopting the above technical solution, the engagement between the inner wall of the groove and the outer wall of the yarn drum can limit the radial sway of the yarn drum. The slide rod passes through the yarn drum laterally and engages with the inner wall of the connecting block, further limiting the axial displacement of the yarn drum. The connecting block and the yarn drum are stably fixed. The motor can drive the yarn drum to rotate through the connecting block, so that the exit position and angle of the yarn are kept stable when it is released. The yarn tension conveyed by the yarn feeding component is stable, without interlacing or impurities. The processing component can continuously receive qualified yarn, improving the stability of the yarn feeding device.

[0007] Optionally, the yarn feeding assembly includes a second motor and a yarn feeding wheel. The second motor is fixed to the upper end of the processing table, the yarn feeding wheel is located on one side of the yarn bobbin, the yarn is wound on the yarn feeding wheel, and the output shaft of the second motor is coaxially fixed with the yarn bobbin.

[0008] By adopting the above technical solution, the output shaft of the second motor is fixed coaxially with the yarn bobbin, so that the rotation speed of the yarn bobbin and the driving speed of the feed wheel can be synchronously controlled. When the second motor drives the feed wheel to rotate and pull the yarn, the yarn bobbin will rotate synchronously with the second motor to release the yarn. This reduces the problems of yarn breakage due to excessively fast pulling of the feed wheel and loose and piled yarn due to excessively slow pulling of the feed wheel, and improves the stability of the device.

[0009] Optionally, a guide reel and an inlet tube are provided on one side of the feed wheel, and the yarn passes through the guide reel and the inlet tube at once and is wound around the surface of the feed wheel.

[0010] By adopting the above technical solution, the guide disc guides the yarn, ensuring that the yarn enters the subsequent inlet tube at a stable angle. After passing through the guide disc, the yarn enters the inlet tube. The tubular structure of the inlet tube constrains the yarn, reducing the axial swing of the yarn and allowing the yarn to wind around the surface of the feed wheel in a near-straight path.

[0011] Optionally, the processing components include a processing box, a third motor, a disc, a winding frame, a syringe, and a thread hook. The processing box is fixed to the upper end of the processing platform, the third motor is fixed inside the processing box, the disc is coaxially fixed with the output shaft of the third motor, the winding frame is located at the upper end of the processing box, the belt is located between the disc and the winding frame, and the belt is tumblingly connected to the disc and the winding frame, the syringe is located inside the winding frame, and the thread hook is fixed to one side of the winding frame. During processing, the thread hook hooks the yarn.

[0012] By adopting the above technical solution, the motor drives the disc to rotate, the disc drives the winding frame to rotate via a belt, the hook catches the yarn, the rotation of the winding frame drives the hook to rotate, and the unloading component releases the yarn synchronously. The yarn caught by the hook can be accurately wound onto the knitting needles of the needle cylinder to form a stocking.

[0013] Optionally, the lower end of the winding frame is provided with two feeding rollers, which are arranged in a transverse direction. After the yarn is processed into socks, it passes between the two feeding rollers. One end of the feeding roller is provided with a gear, and the two gears mesh with each other. The processing box is provided with a motor four, and the output shaft of the motor four is coaxially fixed with any gear.

[0014] By adopting the above technical solution, when the motor drives the four-wheel drive, the two feeding rollers rotate in opposite directions and at the same speed through gear meshing. The socks pass between the two feeding rollers. The clamping force of the two feeding rollers can smooth out the slight wrinkles that may occur during the molding process, while keeping the socks flat during transportation, thus improving the convenience of using the device.

[0015] Optionally, the upper end of the connecting block is provided with a circular block, which is slidably connected to the machine body in a vertical direction. A limiting groove is opened in the circular block, and the yarn bobbin fits against the inner wall of the limiting groove.

[0016] By adopting the above technical solution, when installing the yarn spool, the vertical position of the ring block can be adjusted according to the height of the yarn spool, which can accommodate more sizes of yarn spools and improve the flexibility of the device. At the same time, the ring block cooperates with the connecting block to achieve vertical positioning of the yarn spool, reducing the probability of the yarn spool shaking during yarn release and improving the stability of the device.

[0017] Optionally, a yarn exit roller is provided on one side of the connecting block. The yarn passes through the yarn exit roller, and a tension sensor is provided inside the yarn exit roller. During the yarn conveying process, the tension sensor detects the change in the yarn tension. A clamping assembly is provided between the yarn bobbin and the yarn exit roller. When the tension detector detects that the yarn tension has disappeared, the clamping assembly clamps the yarn.

[0018] By adopting the above technical solution, the tension sensor inside the yarn output roller can detect the change in tension force during the yarn conveying process in real time and transmit the data to the control system. When the yarn breaks, the tension detection device detects the disappearance of tension force, and the control system starts to clamp and fix the broken yarn end, reducing the occurrence of yarn slippage and improving the stability of the device.

[0019] Optionally, the clamping assembly includes a cylinder, a push rod, two pressing rollers, and two connecting rods. The cylinder is fixed to the upper end of the frame, the push rod is fixed to the output end of the cylinder, the two pressing rollers are located at the upper end of the frame, and the two pressing rollers are slidably connected to the frame vertically. The yarn passes between the two pressing rollers. The connecting rods correspond one-to-one with the pressing rollers, and the connecting rods are fixed to one end of the corresponding pressing rollers. Both connecting rods are rotatably connected to the rotating rod.

[0020] By adopting the above technical solution, when the tension sensor detects that the yarn tension has disappeared, the cylinder can drive the push rod. When the push rod pushes the rotating rod to rotate, the two connecting rods will synchronously drive the corresponding pressing rollers to slide vertically, so that the two pressing rollers cooperate to clamp the yarn.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The engagement between the inner wall of the groove and the outer wall of the yarn drum restricts the radial sway of the yarn drum. The slide rod passes through the center hole of the yarn drum laterally and engages with the inner wall of the connecting block, further restricting the axial displacement of the yarn drum. The stable fixation of the connecting block and the yarn drum allows the motor to drive the yarn drum to rotate through the connecting block, keeping the yarn release position and angle stable and improving the stability of the yarn feeding device. 2. When installing the yarn bobbin, the vertical position of the ring block can be adjusted according to the height of the yarn bobbin to accommodate more sizes of yarn bobbins and improve the flexibility of the device. 3. When the motor is driven by four wheels, the two feeding rollers rotate in opposite directions and at the same speed through gear meshing. The garter belt passes between the two feeding rollers. The clamping force of the two feeding rollers can smooth out any slight wrinkles that may occur during the molding process, while keeping the garter belt flat during transport, thus improving the ease of use of the device.

[0028] The present application will be further described in detail below with reference to all the accompanying drawings.

[0029] This application discloses a thread feeding device for a sock-shaking machine. Example

[0030] Reference Figure 1 and Figure 2A yarn feeding device for a sock-shaking machine includes a processing table 1. A connecting block 11 is provided at the upper end of the processing table 1. The connecting block 11 has a groove. A yarn bobbin 111 is inserted into the groove and engaged with the inner wall of the groove. A sliding rod 112 is provided on one side of the connecting block 11. The sliding rod 112 is slidably connected to the connecting block 11 in the transverse direction. After the yarn bobbin 111 is placed in the groove, the sliding rod 112 is slid to pass through the yarn bobbin 111 and engage with the inner wall of the connecting block 11, thereby positioning the yarn bobbin 111 in the transverse direction and reducing the probability of the yarn bobbin 111 tipping over when pulling the yarn laterally. Reference Figure 1 and Figure 2 When the yarn spool 111 needs to be replaced, the operator pulls the slide bar 112 in the opposite direction to remove it from the inner hole of the yarn spool 111 and the through hole of the connecting block 11. At this time, the yarn spool 111 is only initially limited by the groove, and the operator can directly remove the empty yarn spool 111 from the groove, insert the new yarn spool 111 into the groove, and repeat the above steps of fixing the slide bar 112. The entire replacement process does not require any tools, making it easy to replace the yarn spool 111 and improving the convenience of using the device. The inner wall of the groove is equipped with a silicone pad to cushion the impact force when the yarn spool 111 is inserted.

[0031] Reference Figure 1 and Figure 2 The upper end of the connecting block 11 is provided with a circular ring block 15, which is slidably connected to the machine body vertically. When installing the yarn bobbin 111, the circular ring block 15 can be slid according to the height of the yarn bobbin 111 to adjust the position of the circular ring block 15, so as to adapt to more sizes of yarn bobbins 111 and improve the flexibility of the device. A limiting groove 151 is opened in the circular ring block 15. The yarn bobbin 111 fits against the inner wall of the limiting groove 151, reducing the probability of deviation during the subsequent yarn rotation of the yarn bobbin 111 and improving the stability of the device.

[0032] Reference Figure 1 A yarn exit roller 16 is provided on one side of the connecting block 11. The yarn passes through the yarn exit roller 16. A tension sensor 161 is provided inside the yarn exit roller 16. A clamping assembly 17 is provided between the connecting block 11 and the yarn exit roller 16. The tension sensor monitors the change in tension of the yarn on the yarn exit roller 16 in real time and transmits the data to the control system. When the yarn breaks, the tension detection device detects the disappearance of tension, and the control system starts to clamp and fix the broken yarn end.

[0033] Reference Figure 1 and Figure 3The clamping assembly 17 includes a cylinder 171, a push rod 172, two pressing rollers 174, and two connecting rods 173. The cylinder 171 is fixed to the upper end of the frame, and the push rod 172 is fixed to the output end of the cylinder 171. When the tension sensor 161 detects that the yarn tension has disappeared, the control system controls the cylinder 171 to start and drive the push rod 172 to move. The two pressing rollers are located at the upper end of the frame, and the two pressing rollers 174 are slidably connected to the frame vertically. The yarn passes between the two pressing rollers 174. The connecting rods 173 correspond one-to-one with the pressing rollers 174. The connecting rods 173 are fixed to one end of the corresponding pressing rollers 174, and both connecting rods 173 are rotatably connected to the rotating rod. When the push rod 172 moves and drives the rotating rod to rotate, the two connecting rods 173 will synchronously drive the corresponding pressing rollers 174 to slide vertically, so that the two pressing rollers 174 cooperate to clamp the yarn.

[0034] Reference Figure 1 A yarn feeder 122 is provided on one side of the yarn output roller 16. The yarn is wound on the yarn feeder 122. A second motor 121 is provided on one side of the yarn feeder 122. The output shaft of the second motor 121 is fixed coaxially with the yarn. The second motor 121 controls the rotation speed of the yarn bobbin 111. The yarn bobbin 111 releases the yarn as the second motor 121 rotates. A first motor 113 is fixed at the lower end of the connecting block 11. The output shaft of the first motor 113 is fixed coaxially with the connecting block 11. The first motor 113 drives the yarn bobbin 111 to rotate. It can cooperate with the yarn bobbin 111 to adjust the yarn tension and improve the flexibility of the device.

[0035] Reference Figure 1 The yarn feeder 122 has a guide roller 123 and a yarn inlet tube 124 on one side. The guide roller 123 guides the yarn to ensure that the yarn enters the subsequent yarn inlet tube 124 at a stable angle. After passing through the guide roller 123, the yarn enters the yarn inlet tube 124. The tubular structure of the yarn inlet tube 124 will constrain the yarn, reduce the axial swing of the yarn, and allow the yarn to be wound on the surface of the yarn feeder 122 in a near-straight path.

[0036] Reference Figure 4 and Figure 5A wire feed roller 122 is provided with a wire guide frame 137 on the side away from the wire guide reel 123. A processing assembly 13 is provided at the upper end of the frame. The yarn wound on the wire feed roller 122 is guided through the wire guide frame 137 and then reaches the processing assembly 13. The processing assembly 13 includes a processing box 131, a motor 132, a disc 133, a winding frame 134, a syringe 135, and a wire hook 136. The processing box 131 is fixed to the upper end of the processing platform. The motor 132 is fixed inside the processing box 131. The disc 133 is coaxially fixed with the output shaft of the motor 132. The winding frame 134 is located in the processing box 131. At the upper end, the belt is located between the disc 133 and the winding frame 134, and the belt is tumblingly connected to both the disc 133 and the winding frame 134. The motor 132 drives the disc 133 to rotate, and the disc 133 drives the winding frame 134 to rotate via the belt. The cylinder 135 is located inside the winding frame 134, and the thread hook 136 is fixed to one side of the winding frame 134. During processing, the thread hook 136 hooks the yarn, and the rotation of the winding frame 134 drives the thread hook 136 to rotate. The thread feed wheel 122 releases the yarn synchronously, and the yarn hooked by the thread hook 136 can be accurately wound onto the knitting needles of the cylinder 135 to form a stocking.

[0037] Reference Figure 4 and Figure 5 The processing box 131 is equipped with a motor 142. The lower end of the winding frame 134 is equipped with two feeding rollers 14. The feeding rollers 14 are arranged horizontally, and one end of the feeding rollers 14 is equipped with a gear 141. The two gears 141 mesh with each other. The output shaft of the motor 142 is coaxially fixed with the gear 141. When the motor 142 starts, it drives the two meshing gears 141 to rotate synchronously. The rotation of the gears 141 drives the two feeding rollers 14 to rotate in opposite directions at the same speed. The garter belt passes between the two feeding rollers 14. The clamping force of the two feeding rollers 14 can smooth out the slight wrinkles that may occur during the molding process, while keeping the garter belt flat during transportation, thus improving the convenience of using the device.

[0038] The implementation principle of the yarn feeding device of the sock shaking machine according to the present application embodiment is as follows: When installing the yarn spool 111, the yarn spool 111 is placed in the groove, the sliding rod 112 is slid to pass through the yarn spool 111 and position the yarn spool 111 in the horizontal direction, the sliding ring block 15 is slid to make the ring block 15 fit tightly against the yarn spool 111, and the ring block 15 cooperates with the connecting block 11 to realize the vertical positioning of the yarn spool 111, reducing the probability of the yarn spool 111 tipping over during processing and improving the stability of the device.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
