Description

Technical Field

[0001] This application relates to the field of sock knitting technology, and in particular to a segmented micro-support calf muscle sock and its manufacturing equipment. Background Technology

[0002] Calf muscle stockings are functional knitted garments designed specifically for the calf muscles. They are widely used in sports protection, shaping for prolonged sitting or standing at work, and lower limb vein care. Their core function is to provide appropriate pressure to the calf muscles, relieving muscle fatigue, preventing muscle relaxation, and addressing poor blood circulation in the lower limbs. Currently, most conventional calf muscle stockings on the market have a simple design, using a uniform knitted structure with consistent pressure parameters throughout. This makes them unsuitable for adapting to the muscle distribution, stress characteristics, and physiological structure of different parts of the calf.

[0003] The human calf is composed of multiple muscle groups, including the gastrocnemius and soleus muscles. The thickness, tension, and daily stress levels of different muscle groups vary significantly. The physiological pressure requirements of the upper, middle, lower calf and the ankle joint are different. Muscle stockings with uniform pressure either have insufficient overall pressure, failing to achieve effective muscle micro-lifting, shaping, and protection, or have excessive overall pressure, compressing blood vessels and nerves. Wearing them for a long time can easily lead to discomfort such as soreness, numbness, and stuffiness, resulting in extremely poor fit and comfort.

[0004] Meanwhile, existing muscle sock production equipment has a rigid structure and mostly adopts a single-needle fixed knitting mode, which can only produce socks with a single density and a single pressure, and cannot achieve segmented and differentiated knitting processing of socks.

[0013] In some embodiments, the needle mechanism includes: A carrier plate has at least three grooves and one slot. A lead screw is rotatably installed in each groove. A second nut slider is threaded onto the lead screw. A syringe is fixed on the second nut slider. A drive motor is mounted on a support plate. A first bevel gear is fixed to the output end of the drive motor. At least three second bevel gears mesh on the first bevel gear.

[0016] A segmented micro-lifting calf sock, the calf muscle sock is knitted by the aforementioned manufacturing equipment. The calf muscle sock is divided into three segmented knitted areas along its length: an upper gastrocnemius muscle support area, a middle muscle-contact area, and a lower ankle buffer area. These three segments are knitted using three different sets of needle mechanisms. The yarn density in the upper gastrocnemius muscle support area is greater than that in the middle muscle-contact area, and the elasticity of the knitted loops in the lower ankle buffer area is greater than that in the upper and middle sections, forming a segmented micro-lifting pressure structure that is tighter at the top, softer in the middle, and elastic at the bottom. The transitions between the segments are smooth, without raised pressure lines, and the pressure value of each segment is precisely controlled synchronously by the equipment's tension adjustment component and sinker adjustment component to adapt to the physiological pressure requirements of different calf muscle groups. The beneficial effects of this application are as follows: It features three sets of switchable knitting mechanisms, coupled with synchronously linked tension adjustment components and sinker adjustment components, allowing for differentiated knitting processing of the upper, middle, and lower sections of the calf muscle stockings. The resulting stockings possess a segmented micro-support structure that is tight at the top, soft in the middle, and elastic at the bottom. The high-density knitting structure in the upper section precisely supports the relaxed gastrocnemius muscle, effectively alleviating muscle sagging and soreness caused by exercise, prolonged sitting, or standing. The moderate pressure structure in the middle section conforms to the main calf muscle groups, achieving even fit and protection, avoiding excessive compression. The high-elasticity knitting structure in the lower section adapts to the needs of ankle movement, balancing coverage and flexibility. The smooth transition between each segment without pressure seams or protrusions solves the problems of poor pressure fit and localized discomfort associated with traditional uniform-pressure muscle stockings, precisely matching the stress and physiological needs of different calf muscle groups. Abandoning the traditional model of independent tension and sinker adjustment, this system achieves synchronous drive adjustment of the tension and sinker adjustment components through a linkage transmission mechanism. When switching between different needle mechanisms for segmented knitting, precise adjustments to yarn tension and sinker working position can be made simultaneously, accurately controlling yarn density, loop size, and forming tightness in each segment. Furthermore, the structural design of the beveled tensioner and adjusting ring, along with the double-beveled, graded drive of the sinker on the driving ring, significantly improves fine-tuning accuracy. This solves the problems of large adjustment errors, inconsistent segmented forming parameters, and uneven product quality inherent in traditional equipment, effectively ensuring uniform segmented pressure parameters and stable forming quality in mass-produced muscle socks.

The tension adjustment component 6 and the settling plate adjustment component 7 are synchronously driven by a transmission component 8, which is driven by the switching mechanism 3. The tension adjustment assembly 6 includes an adjustment ring 61, an adjustment rod 62, a pull rope 63, a bottom ring 64, and a return spring 65. One end of the pull rope 63 is fixedly connected to the bottom ring 64, and the other end is fixedly connected to the pull wire frame 42. The adjustment ring 61 is fixed to the frame 1, and the adjustment rod 62 is rotatable and passes through the frame 1. The adjusting ring 61 has a chamfer that abuts against the inclined surface of the wire puller 42; the chamfer makes the cross-section of the adjusting ring 61 form another inclined surface that matches the inclined surface of the wire puller 42. One end of the return spring 65 is fixedly connected to the support ring 41, and the other end is fixedly connected to the bottom ring 64.

[0033] Furthermore, the top of the adjusting rod 62 is provided with a threaded end, and a first nut slider is threaded on the threaded section, which is fixedly connected to the adjusting ring 61; A guide block is fixedly provided on the adjusting ring 61.

[0034] The threaded end of the adjusting rod 62 drives the first nut slider to move, which in turn drives the adjusting ring 61 to move. The chamfer inside the adjusting ring 61 cooperates with the inclined surface on the pull wire frame 42 to drive the pull wire frame 42 to move, thereby adjusting the tension. The tension adjustment is to tighten or loosen. When used to tighten the tension, the adjusting ring 61 moves downward, driving the pull wire frame 42 to drive the pull rope 63 to move, and also simultaneously driving the bottom ring 64 to move, overcoming the force of the return spring 65. When used to loosen the tension, the adjusting ring 61 moves upward, the return spring 65 is no longer under force, and the bottom ring 64 is driven to move under the force of the tension return spring, driving the pull rope 63 and the pull wire frame 42.

[0035] Furthermore, the support ring 41 is provided with a pulley 43, which is used to support and guide the pull rope 63; the pulley 43 is provided to support and guide the pull rope 63, and can also effectively prevent the pull rope 63 from wearing. A guide rod is fixed to the bottom of the support ring 41, and the guide rod is slidably connected to the bottom ring 64.

[0036] Furthermore, the frame 1 is provided with a guide rail, and the guide block is slidably connected to the guide rail; the cooperation between the guide rail and the guide block is used to support the adjusting ring 61 and limit the movement trajectory of the adjusting ring 61.

[0037] Furthermore, the settling plate mechanism 5 includes a positioning ring 51, on which a plurality of connecting grooves are provided, and a settling plate 52 is slidably disposed in each of the connecting grooves; A vertical plate 53 and a vertical rod 54 are fixed on the settling plate 52. The vertical plate 53 is slidably provided with a connecting groove. The positioning ring 51 is fixed to the frame 1 by a concave plate.

[0038] Furthermore, the settling plate adjustment assembly 7 includes: The drive ring 71 has a primary drive ramp 72 and a secondary drive ramp 73 that cooperate with the upright 54; the drive ring 71 is rotatably mounted on a support block on the positioning ring 51.

When the rotating rod 76 rotates, the transmission gear 77 drives the gear ring 75 to rotate, which in turn drives the drive ring 71 to move. The drive ring 71 then drives the upright rod 54 via a primary drive inclined surface 72 or a secondary drive inclined surface 73, thereby driving the settling plate 52 to overcome the torsion spring movement and achieve matching between the settling plate 52 and the tension.

[0039] Furthermore, the needle mechanism 2 includes: The carrier plate 21 has at least three grooves and one slot. Each groove is rotatably provided with a lead screw 22. The lead screw 22 is threaded with a second nut slider. The second nut slider is fixed with a needle cylinder 23. The needle cylinder 23 is equipped with knitting needles. The needle cylinder 23 also integrates a lifting module for driving the knitting needles to rise and fall. A drive motor 24 is mounted on a support plate 21. A first bevel gear is fixed to the output end of the drive motor 24. At least three second bevel gears mesh on the first bevel gear. One end of the lead screw 22 passes through the groove and is connected to the second bevel gear; the first bevel gear is driven to rotate by the drive motor 24, which in turn drives the second bevel gear to rotate, and the lead screw 22 is driven to rotate by the second bevel gear, and the position of the syringe 23 is adjusted by the second nut slider on the lead screw 22. The syringe changing mechanism 3 includes a syringe changing motor 31, which is fixed inside the frame 1. A drive rod 32 is fixed to the output end of the syringe changing motor 31. One end of the drive rod 32 passes through the frame 1 and is connected to the support plate 21. The syringe changing motor 31 drives the drive rod 32 to rotate, which in turn drives the support plate 21 to rotate, thereby enabling the changing of different syringes 23 for operation.

[0040] Furthermore, the transmission assembly 8 includes: At least three transmission rods 81, each with a third bevel gear fixed at both ends; the transmission rods 81 are rotatably mounted on the vertical plate 53 at the top of the frame 1; At least three fourth bevel gears mesh with three third bevel gears respectively. An output rod 82 is fixed on the fourth bevel gear. The output rod 82 is fixedly connected to the adjusting rod 62. The output rod 82 is rotatably mounted on the frame 1 and the protective cover 11, and one end of it passes through the protective cover 11. At least three drive discs 83, each of which is provided with partial teeth 84, are indexed in a manner such that the partial teeth 84 on the three drive discs 83 are spaced apart, and the drive discs 83 are fixed to the drive rod 32; when viewed from above, the three drive discs 83 overlap, and the partial teeth 84 on the three drive discs 83 are spaced apart.

A connecting shaft is fixed to each driven gear 85, and the connecting shaft is rotatably mounted on the protective cover 11. A fifth bevel gear is fixed to the connecting shaft, and the fifth bevel gear meshes with the third bevel gear. The three driven gears 85 are not coaxial.

[0041] Furthermore, the transmission assembly 8 also includes: An intermediate rod 86 is provided with a worm gear section, which meshes with a worm wheel 87. The worm wheel 87 is connected to a rotating rod 76 via a transmission. The intermediate rod 86 is rotatably mounted on the frame 1. The worm wheel 87 and the worm gear section are designed to achieve self-locking and prevent the settling plate from retracting during adjustment. The worm wheel 87 and the rotating rod 76 can be driven by a bevel gear or a universal joint. In this application, a bevel gear transmission is preferred. The system includes a large pulley, a small pulley, and a synchronous belt connecting the two pulleys. The small pulley is fixed to the intermediate rod 86, while the large pulley is fixed to the output rod 82. The large and small pulleys are configured to create a differential speed to match the adjustment of the settling plate 52.

[0042] The drive rod 32 is driven to rotate by the change group motor 31. The drive rod 32 drives the three drive discs 83 to rotate synchronously. Depending on the selected syringe 23, the partial teeth 84 on the different drive discs 83 drive the different driven gears 85 to rotate, thereby causing the output rod 82 to rotate a different number of revolutions. The output rod 82 synchronously drives the intermediate rod 86 and the adjusting rod 62 to rotate. The rotation of the adjusting rod 62 is used to adjust the yarn tension. The rotation of the intermediate rod 86 drives the rotating rod 76 to rotate, thereby adjusting the sinker 52.

[0043] A segmented micro-support calf muscle sock is knitted by the aforementioned manufacturing equipment. The sock is divided into three segmented knitted areas along its length: an upper gastrocnemius muscle support area, a middle muscle-contact area, and a lower ankle buffer area. These three areas are knitted using three different sets of needle mechanisms. The yarn density in the upper gastrocnemius muscle support area is greater than that in the middle muscle-contact area, while the elasticity of the knitted loops in the lower ankle buffer area is greater than that in the upper and middle sections, forming a segmented micro-support pressure structure that is tighter at the top, softer in the middle, and elastic at the bottom. The transitions between the segments are smooth, without raised pressure lines, and the pressure value of each segment is precisely controlled synchronously by the equipment's tension adjustment component and sinker adjustment component to adapt to the physiological pressure requirements of different calf muscle groups.
