Description

Technical Field

[0001] The invention relates to the technical field of knitting machines, in particular to a control system for a multi-axial socks knitting machine. Background Art

[0002] With the continuous development of textile technology, multi-axial hosiery knitting machines are favored because they can produce socks with high strength, high elasticity and complex patterns. However, when dealing with multi-axial knitting, traditional hosiery knitting machine control systems often have problems such as inflexible adjustment of yarn input angles, easy friction with wires, resulting in yarn breakage or wire thinning. These problems not only affect the quality and production efficiency of socks, but also increase production costs.

[0003] For example, a Chinese patent discloses "A single-needle sewing mechanism and sewing process for the toe of an automatic hosiery machine" (publication number: CN110284268B), which discloses a single-needle sewing mechanism and sewing process for the toe of an automatic hosiery machine, including a single-needle sewing control system, a sewing starting position reset system and a single-needle sewing system. The single-needle sewing mechanism and sewing technology for the toe of an automatic hosiery machine involved in the present invention are simpler in structure and more stable in operation than the original traditional double-needle sewing technology. The sewing seams are flat and have good extensibility. The texture is far superior to the double-needle sewing seams. It is the best choice for an intelligent one-piece fully automatic hosiery machine.

[0004] However, the control system of the above patented hosiery machine can usually only input yarn at a fixed angle and cannot make real-time adjustments according to changes in the knitting direction. This results in the yarn easily rubbing against the wire during the multi-axial knitting process, especially when the knitting direction changes frequently, the friction problem is particularly prominent.

[0005] Secondly, the control system of traditional hosiery knitting machines lacks intelligent adjustment functions and cannot automatically adjust the yarn input angle according to the requirements of knitting patterns and density. This results in the yarn being easily damaged when producing complex patterns or high-density socks, which in turn affects the overall quality and appearance of the socks. Summary of the invention

[0033] The embodiment of the present invention provides a multi-axial hosiery knitting machine control system, such as Figure 1-8 As shown, it includes a hosiery machine base 101, a product guiding platform 102, a weaving box 103, a support inner ring 110, a support outer ring 111 and a support splint 113. The product guiding platform 102 is fixedly arranged at the front end of the hosiery machine base 101. The top of the product guiding platform 102 is provided with an inclined surface for guiding the product to slide and move. The weaving box 103 is arranged at the top of the hosiery machine base 101. The front end of the hosiery machine base 101 is provided with a weaving cavity 116 opening outward, and the weaving cavity 116 opens toward the product guiding platform 102. Four pillars 104 are fixedly set at the four corners of the top of the hosiery machine base 101. Two support splints 113 are cross-framed on the top of the pillars 104. Four connecting pillars 112 are set on the tops of the supporting splints 113 on both sides. The connecting pillars 112 are symmetrically arranged. The inner support ring 110 is fixedly connected to the tops of the four inner connecting pillars 112, and the outer support ring 111 is fixedly connected to the four outer connecting pillars 112.

[0034] It should be further explained that the inner support ring 110 and the outer support ring 111 are respectively in a circular ring shape, and the inner support ring 110 and the outer support ring 111 are arranged in a coaxial position.

[0035] Furthermore, an equal number of adjustment sliders 108 are respectively provided at the top of the support inner ring 110 and the support outer ring 111, and the adjustment sliders 108 are arranged in a circular array. A circular adjustment rotating ring 109 is rotatably provided at the top of the support inner ring 110 and the support outer ring 111, and the adjustment rotating ring 109 is installed and connected to the adjustment sliders 108 on each side.

[0036] It should be further explained that the adjusting slider 108 and the adjusting rotating ring 109 are connected by studs.

[0037] Furthermore, a rotation adjuster 105 is fixedly provided on one side of the outer end surface of the supporting outer ring 111 . The rotation adjuster 105 is connected to the adjusting rotating ring 109 . A tooth groove is provided at the connection position between the adjusting rotating ring 109 and the rotation adjuster 105 .

[0038] It should be noted that a rotating gear is provided inside the rotating adjuster 105 and meshes with the teeth on the surface of the adjusting rotating ring 109. A rotating motor is fixed inside the rotating adjuster 105. The rotating motor drives the gear to rotate and drives the adjusting rotating ring 109 to rotate and adjust the direction on the surface of the supporting outer ring 111 through meshing.

[0039] Furthermore, a support tube 107 is installed between the adjusting sliders 108 on the inner and outer sides. The support tube 107 is U-shaped. A bobbin 106 is rotatably provided at the bottom of the support tube 107 , and a spinning thread 123 is wound around the outer end surface of the bobbin 106 .

[0040] Furthermore, four reversing adjustment shafts 124 are rotatably provided at the top of the two supporting splints 113. The positions of the reversing adjustment shafts 124 are distributed in a matrix. A pulley 121 is installed at the top of the reversing adjustment shaft 124. A welding plate 127 shorter than the supporting splint 113 is installed at the intersection of the two supporting splints 113. The top of the welding plate 127 is rotatably connected to a driving pulley 126. The same adjusting belt 122 is wound around the driving pulley 126 and the four pulleys 121.

[0041] It should be further explained that a rotating motor is provided at the bottom of the welding plate 127, and the rotating motor is power-connected to the driving pulley 126. When the rotating motor is started, it can drive the driving pulley 126 to rotate. At this time, the driving pulley 126 rotates and the winding adjustment belt 122 drives the pulleys 121 on each side to rotate.

[0042] Furthermore, an inclined angle adjustment base 120 is installed and connected to the top of the pulley 121 , and an integrated bobbin 125 is rotatably connected to the top of the angle adjustment base 120 .

[0043] It is worth mentioning that the yarn 123 wound around the outer end surfaces of several bobbins 106 can be wound onto the same integrated bobbin 125, achieving the effect of winding and combining, playing the role of mixed connection of the combined yarns, and forming a thicker braiding yarn, which is convenient for meeting the technological requirements of sock weaving and carrying out subsequent sock weaving work.

[0044] It should be further explained that a tension sensor is disposed in the angle adjustment base 120 for monitoring the tension of the spinning thread 123 input from the surface of the integrated bobbin 125 .

[0045] Furthermore, two adjusting grooves 117 that are connected to each other up and down are provided on both sides of the top of the weaving cavity 116. The adjusting grooves 117 on both sides are symmetrically arranged. A movable wire mold 129 is movably provided in the adjusting groove 117. Telescopic springs 130 are installed and connected between the two ends of the movable wire mold 129 and the two side walls of the adjusting groove 117. The movable wire mold 129 is provided with an integrated supporting wire hole 128 that is connected to each other up and down.

[0046] It should be further noted that after the yarn 123 is centrally integrated on the surface of the integrated yarn barrel 125 , the other end of the integrated yarn 123 extends and passes through the integrated support wire hole 128 and moves into the weaving cavity 116 .

[0047] Furthermore, two knitting machine bases 114 are fixedly installed in the knitting cavity 116 and at the top of the sock knitting machine base 101. The knitting machine bases 114 on both sides are symmetrically arranged. An adjustment chamber 133 opening outward is provided at the front end of the knitting machine base 114, and the adjustment chamber 133 is L-shaped.

[0048] Furthermore, a transmission shaft 131 is rotatably provided between the two walls of the regulating chamber 133 , a transmission plate 132 is fixedly connected to the outer end surface of the supporting clamping plate 113 , and an L-shaped axial adjuster 118 is installed on the top of the transmission plate 132 .

[0049] It should be noted that a vertical baffle is provided at the vertical position of the front end of the axial adjuster 118 to provide protection.

[0050] It is worth further explaining that, after one end of the yarn 123 extends into the braiding cavity 116, it is connected to the yarn interface at the rear end of the axial regulator 118 and serves as an input.

[0051] Furthermore, a knitting needle cylinder 119 is installed at the front end of the bottom of the axial adjuster 118 , and a textile needle 134 is installed at the bottom of the knitting needle cylinder 119 .

[0052] It should be further explained that the yarn 123 enters through the yarn connection port of the axial regulator 118 and moves to the head of the yarn needle 134, and the knitting work is realized through the cooperation of the yarn needles 134 on both sides.

[0053] It is worth further explaining that an adjusting motor is provided in the adjusting chamber 133, and the adjusting motor is power-connected to the transmission shaft 131. When the adjusting motor is started, it can drive the transmission shaft 131 to rotate, and then drive the axial adjuster 118 to rotate to achieve the effect of adjusting the weaving angle of the textile needle 134.

[0054] It should be noted that the sock knitting machine base 101 is provided with a touch screen display and an industrial computer control system, and is equipped with a human-machine interface device specifically used for industrial automation to display system status, receive user input and send control instructions.

[0055] When using this solution, first install all the components and move the hosiery knitting machine base 101 as a whole to the hosiery knitting working position. At this time, the basic yarn 123 used for knitting is pre-installed on the surface of the bobbin 106, and the pre-installed bobbin 106 is installed in the support tubes 107 on each side. The yarn 123 used for knitting is integrated according to the hosiery knitting process, and is wound on the surface of the integrated bobbin 125 and wound a certain number of times. The other end after integration is passed through the integrated support wire hole 128, and is connected to the textile wire inlet of the axial adjuster 118, and is installed with the textile needle 134 at the front end to complete the preparation work for textile work.

[0056] At this time, according to the requirements of the sock knitting process, the production workers input the process requirements through the touch screen display, and use the set human-machine interface to display the system status, receive user input and send control instructions, thereby controlling each component to perform the sock knitting work.

[0057] When the system is started, the textile needles 134 on both sides cooperate to start the textile thread input and interweave to realize the sock knitting work, and then the completed socks slide down through the guidance of the product guide platform 102. In this process, the spinning thread 123 is continuously pulled through the textile process and drives the integrated bobbin 125 to rotate. At the same time, as the integrated bobbin 125 rotates, the connected fine threads are pulled to integrate, and the textile fine threads on the surface of the corresponding input bobbin 106 are driven to be output.

[0058] As the hosiery knitting work continues, the input angle of the bobbin 106 input to the surface of the integrated bobbin 125 will change with the change in the diameter of the fine wire wrapped on the surface of the bobbin 106, which will cause the traction angle of the yarn 123 to change, and then change the traction angle of the integrated bobbin 125. At this time, the tension of the integrated bobbin 125 is monitored by the tension detector inside the angle adjustment base 120. At this time, due to the change in the angle of the fine wire input on each side, the total tension angle of the integrated bobbin 125 will change due to the change, and the tension will change. At this time, the industrial computer in the hosiery knitting machine base 101 calculates and controls the rotation regulator 105 to start.

[0059] At this time, as the rotating regulator 105 is started, the rotating motor of the rotating regulator 105 drives the gear to rotate, and drives the adjusting rotating ring 109 to rotate and adjust the direction on the surface of the supporting outer ring 111 through meshing. At this time, the adjusting rotating ring 109 rotates and drives the connected adjusting slider 108 to adjust the position, and then by adjusting the position of the adjusting slider 108, the angle of the thin line input in the bobbin 106 is fine-tuned, and then through repeated debugging, the tension of the integrated bobbin 125 is adjusted to the most appropriate force, thereby reducing the friction between the thin line and the integrated bobbin 125, and further reducing the loss of the thin line caused by friction, thereby preventing the problem of breakage of the spinning line 123 caused by thinning.

[0060] At the same time, according to the textile process, if more integrated yarns 123 need to be input and the tension angles of multiple integrated yarns 123 need to be adjusted, the rotating motor provided at the bottom of the welding plate 127 is started, and the rotating motor is power-connected to the active pulley 126, which can drive the active pulley 126 to rotate. At this time, the active pulley 126 rotates and the adjustment belt 122 is wound around it to drive the pulleys 121 on each side to rotate, and the direction is adjusted uniformly, so that the tension of the integrated yarns 123 on each side reaches a balanced state, thereby reducing the problem of uneven input rate of the integrated yarns 123 caused by different tensions, and further improving the subsequent sock weaving work efficiency and the weaving quality of the socks.

[0061] When it is necessary to adjust the angle of the textile needle 134 according to a complex hosiery knitting process, the adjustment motor installed in the adjustment chamber 133 is started, which can drive the transmission shaft 131 to rotate, and then drive the axial adjuster 118 to rotate to adjust the weaving angle of the textile needle 134, thereby achieving a multi-axial weaving angle effect, and providing technical support for the complex hosiery knitting process.

[0062] During the axial adjustment process, as the angle of the axial adjuster 118 changes, the angle of the input yarn 123 changes. At this time, the movable wire mold 129 moves under the contact tension of the yarn 123, overcomes the elastic force of the telescopic spring 130, and fine-tunes the input tension support of the yarn 123, thereby reducing the contact friction between the yarn 123 and the movable wire mold 129. Further, through fine-tuning control, the loss of the yarn 123 can be controlled to a minimum when producing socks with complex patterns or high density, thereby improving the overall quality and appearance of the socks.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
