Description

Technical Field

[0001] This application relates to the field of sock knitting machine technology, and in particular to a double-layer support terry loop shock-absorbing sock and its manufacturing equipment. Background Technology

[0002] As a core knitted product for daily wear and sports protection, socks have seen increasing market demands for functionality, comfort, and durability as fitness and daily sports activities become more widespread. In particular, shock absorption, support, anti-collapse, and breathability in sports scenarios have become core performance indicators. Currently, most shock-absorbing terry socks on the market are made using conventional knitting equipment in a single knitting process. The production equipment has a simple structure and poor functional adjustment capabilities, resulting in many industry pain points.

[0003] Existing hosiery manufacturing equipment often uses fixed yarn tension parameters, making it impossible to adjust the yarn tension according to the different functional needs of different areas of the hosiery. This results in a uniform knitting density throughout the hosiery, making it difficult to achieve functional structural designs for different areas of the foot. The sinker mechanism of traditional equipment is mostly a fixed structure, which cannot achieve the linkage adjustment of circumferential expansion and contraction. The terry loop forming height is fixed, resulting in uniform fluffiness and tightness of the knitted terry loop structure, which cannot adapt to the force requirements of different foot areas such as the heel, forefoot, and arch.

[0004] Meanwhile, traditional terry loop molding structures lack a follow-up limiting and shaping mechanism, which can easily lead to uneven height and skewed molding during the terry loop weaving process. The finished terry loops are soft but lack stiffness, and after long-term wear and stepping, they are prone to collapse, hardening, and deformation. The shock absorption and rebound performance decays rapidly, and it is impossible to achieve a long-term cushioning effect.

It includes a positioning gear ring and several adjustment components. Each set of adjustment components includes an adjustment gear, a lead screw, and an adjustment nut. A driving block is fixed on the positioning toothed ring, and a driving inclined surface is provided on the driving block; The loop retaining ring is located above the sinker plate and is used to limit the forming height of the loop yarn in conjunction with the sinker plate mechanism. It includes a retaining ring and a spring. One end of the retaining ring extends into a horizontal plate, and the bottom of the horizontal plate is provided with a mating surface that mates with the driving inclined surface. The spring is used to provide an elastic force to the horizontal plate so that the mating surface on the horizontal plate keeps in contact with the driving inclined surface on the driving block.

[0008] In some embodiments, the drive gear is driven by a drive motor; The pinion and the driven gear are coaxially fixedly arranged; The outer wall of the drive ring is fixedly provided with a first tooth, and its inner wall is fixedly provided with a second tooth. The first tooth meshes with the drive gear, and the second tooth meshes with the driven gear. The rack meshes with the pinion, and a support frame is fixed to one end of the rack. The wire pull roller is rotatably disposed within the support frame.

[0009] In some embodiments, the tension adjustment unit further includes a support ring frame fixed to the frame, and the top of the support ring frame is provided with an annular groove; A ring block is formed at the bottom of the drive ring, and the ring block is rotatably disposed in the ring groove.

[0010] In some embodiments, the frame is provided with a groove, and a guide rod is fixed in the groove.

[0011] In some embodiments, the horizontal plate is slidably disposed in the groove, and the horizontal plate is provided with a connecting hole that is slidably engaged with the guide rod; The spring is sleeved on the outside of the guide rod, with one end in contact with the inner wall of the groove and the other end in contact with the top of the horizontal plate.

[0012] In some embodiments, the settling plate mechanism includes an annular support, which is mounted on a frame. The annular support has a plurality of grooves evenly distributed along the circumference of the annular support, and a settling plate is slidably disposed in each groove. A limiting ring and a vertical plate are fixed on the annular bracket; The end of the settling plate is fixed with a tail plate.

[0013] In some embodiments, the positioning toothed ring is rotatably disposed on the limiting ring, and the outer wall of the positioning toothed ring is fixed with a third tooth; The adjusting nut is rotatably mounted on the upright plate; The lead screw is threadedly connected to the adjusting nut, and one end of the lead screw is rotatably connected to the tail plate. The adjusting gear meshes with the positioning gear ring, and the adjusting gear is fixedly connected to the adjusting nut. The adjusting gear has a through hole for the lead screw to pass through.

[0014] In some embodiments, the transmission assembly includes a transmission rod and a positioning rod, wherein the transmission rod is coaxially fixed to one of the driven gears, and a first transmission gear is fixed on the transmission rod; The positioning rod is rotatably mounted on the support ring frame. The positioning rod body is provided with a second transmission gear and a third transmission gear from top to bottom. The second transmission gear meshes with the first transmission gear, and the third transmission gear meshes with the third tooth.

[0015] A double-layer support terry loop shock-absorbing sock, comprising a sock body base and a double-layer support terry loop layer on the sole; The sock body is woven from yarn under constant tension, resulting in a smooth and fitted fabric surface; the double-layer support terry layer on the sole is woven from double-layer curled anti-slip yarn and yarn simultaneously. The sole features a zoned structure, with the heel and forefoot areas having a high-loft, shock-absorbing micro-loop structure, and the arch and sides of the sock having a high-tightness, supportive micro-loop structure. The double-layer support terry cloth is shaped by the linkage and follow-up structure, making it upright and sturdy with uniform rebound. It is not easy to collapse or harden under pressure, and can absorb the impact of landing step by step and block the upward transmission of vibration. There is no obvious vibration in the back of the head when wearing it for exercise.

[0016] In some embodiments, the double-layered curled anti-slip yarn and the sock body yarn participate in the terry knitting process synchronously. The root of the terry adopts a cross-locking structure to be integrally formed without loose interlayers. After long-term repeated stepping, it can still maintain a three-dimensional vertical support shape and has long-term anti-collapse and fatigue resistance characteristics. The high-loft, shock-absorbing micro-loop loops form a uniform, three-dimensional, breathable cavity inside, balancing cushioning and shock absorption with breathability and heat dissipation; the densely packed, high-support micro-loop loops provide strong support, effectively locking the foot's posture and preventing fatigue from prolonged standing or exercise.

[0017] The beneficial effects of this application are as follows: It incorporates a tension adjustment section, a sinker adjustment mechanism, and a terry loop retainer, creating a linkage structure that overcomes the drawbacks of traditional equipment with fixed parameters and the inability to adjust in different zones. The tension adjustment section precisely adjusts the yarn knitting tension through a drive ring, gear set, and pull-out assembly, allowing for targeted formation of different functional areas within the sock. Simultaneously, the sinker adjustment mechanism, linked to the tension adjustment section through a transmission assembly, synchronously drives the sinker to expand or contract circumferentially. Combined with the follow-up limiting and shaping of the terry loop retainer, it precisely controls the forming height and density of the terry yarn, achieving integrated synchronous knitting of high-loft terry loops at the heel and forefoot with high-density terry loops at the arch and sides. This results in strong process synchronization, high forming precision, and significantly improved product qualification rate and production efficiency. The loop retainer is designed with a spring to continuously provide elastic preload, ensuring that the mating surface of the horizontal plate is always in contact with the driving inclined surface of the drive block. This achieves follow-up positioning and shaping, ensuring that the woven double-layer support loops are upright, neatly arranged, and have uniform rebound. Structurally, this solves the defects of traditional loops that are prone to collapse and clumping. Attached Figure Description

In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0031] This embodiment focuses on the same sock manufacturing equipment. In the first aspect, it provides a double-layer support terry loop shock-absorbing sock manufacturing equipment, and in the second aspect, it provides a double-layer support terry loop shock-absorbing sock.

[0032] Firstly, a device for manufacturing double-layered support terry loop shock-absorbing socks is provided. For example... Figure 1-9 As shown, this embodiment includes a frame 1, a yarn feeding section 2, and a sinker mechanism 3. The frame 1 is further provided with a tension adjustment section 4, a sinker adjustment mechanism 5, and a loop retainer 6. The yarn feeding section 2 is a mechanism for supporting yarn. It is located at the top of the frame 1 and only serves to support the yarn coils and allow the yarn coils to move on it. This is conventional technology and this application does not make any improvements to it, so it is not described in detail. The tension adjustment unit 4 is used to adjust the tension of the yarn during the knitting process to form different functional areas of the sock body, including a drive ring 41, a drive gear 42 and several sets of yarn pulling assemblies 43; The single-unit wire drawing assembly 43 includes a driven gear 4301, a pinion 4302, a rack 4303, and a wire drawing roller 4304; The settling plate adjustment mechanism 5 is linked to the tension adjustment part 4 through a transmission component 7, and is used to drive the settling plate mechanism 3 to expand or contract circumferentially. It includes a positioning toothed ring 51 and several adjustment components 52. Each set of adjustment components 52 includes an adjustment gear 5201, a lead screw 5202 and an adjustment nut 5203. A driving block 53 is fixed on the positioning toothed ring 51, and a driving inclined surface is provided on the driving block 53; The loop retaining ring 6 is located above the sinker 32 and is used to cooperate with the sinker mechanism 3 to limit the forming height of the loop yarn. It includes a retaining ring 61 and a spring 62. One end of the retaining ring 61 extends a horizontal plate 63, and the bottom of the horizontal plate 63 is provided with a mating surface that cooperates with the driving inclined surface. The spring 62 is used to provide an elastic force to the horizontal plate 63 so that the mating surface on the horizontal plate 63 keeps in contact with the driving inclined surface on the driving block 53.

[0033] The drive gear 42 is driven by a drive motor; the drive motor and the drive gear 42 are connected by a transmission shaft. The pinion 4302 and the driven gear 4301 are coaxially fixedly arranged; The outer wall of the drive ring 41 is fixedly provided with a first tooth, and the inner wall is fixedly provided with a second tooth. The first tooth meshes with the drive gear 42, and the second tooth meshes with the driven gear 4301. The rack 4303 meshes with the pinion 4302. One end of the rack 4303 is fixed to a support frame 4305, and the pull roller 4304 is rotatably disposed within the support frame 4305. At least two pull rollers 4304 are provided in a single support frame 4305 to match the adjustment of tension and relaxation.

[0034] The tension adjustment unit 4 also includes a support ring frame 44, which is fixed on the frame 1. The top of the support ring frame 44 is provided with an annular groove. The drive motor for providing driving force to the drive gear 42 is installed at the bottom of the support ring frame 44. The rack 4303 is slidably engaged with the guide block on the support ring frame 44. While providing support for the rack 4303, the movement trajectory of the rack 4303 is limited. Furthermore, it provides movement space for the rack 4303 and the drive ring 41, so that the two do not interfere with each other and ensure the normal operation of the device. A ring-shaped block is formed at the bottom of the drive ring 41, and the ring-shaped block is rotatably disposed within the ring groove. The arrangement of the ring-shaped block and the ring groove limits the movement trajectory of the drive ring 41.

[0035] The drive motor drives the drive gear 42 to rotate, which in turn causes the drive ring 41 to rotate, driving the driven gear 4301 and the pinion 4302 to rotate. The pinion 4302 drives the rack 4303 to move, which in turn drives the support frame 4305 and the tension roller 4304 to move, thereby adjusting the tension of the yarn passing through the tension roller 4304.

[0036] The frame 1 is provided with a groove, and a guide rod is fixed in the groove.

[0037] The horizontal plate 63 is slidably disposed in the groove, and the horizontal plate 63 is provided with a connecting hole that is slidably engaged with the guide rod; The spring 62 is sleeved on the outside of the guide rod, with one end in contact with the inner wall of the groove and the other end in contact with the top of the horizontal plate 63.

[0038] The settling plate mechanism 3 includes an annular support 31, which is mounted on the frame 1. The annular support 31 has several grooves evenly distributed around its circumference, and a settling plate 32 is slidably disposed in each groove. A limiting ring and a vertical plate are fixed on the annular bracket 31; The end of the settling plate 32 is fixed with a tail plate 33.

[0039] The positioning toothed ring 51 is rotatably mounted on the limiting ring, and a third tooth is fixed to the outer wall of the positioning toothed ring 51; the third tooth is a partial tooth. The adjusting nut 5203 is rotatably mounted on the upright plate; The lead screw 5202 is threadedly connected to the adjusting nut 5203, and one end of the lead screw 5202 is rotatably connected to the tail plate 33. The adjusting gear 5201 meshes with the positioning gear ring 51, and the adjusting gear 5201 is fixedly connected to the adjusting nut 5203. The adjusting gear 5201 has a through hole for the lead screw 5202 to pass through.

[0040] The transmission assembly 7 includes a transmission rod 71 and a positioning rod 72. The transmission rod 71 is coaxially fixed with one of the driven gears 4301, and a first transmission gear 73 is fixed on the transmission rod 71. A protective cover is provided on the outside of the transmission assembly 7, and the protective cover is fixedly installed on the frame 1. The positioning rod 72 is rotatably mounted on the support ring frame 44. From top to bottom, the positioning rod 72 has a second transmission gear 74 and a third transmission gear 75. The second transmission gear 74 meshes with the first transmission gear 73, and the third transmission gear 75 meshes with the third tooth. The first transmission gear 73, the second transmission gear 74, and the third transmission gear 75 are transmission gears of different sizes, with their dimensions decreasing from largest to smallest as follows: third transmission gear 75, first transmission gear 73, and second transmission gear 74. This configuration forms a transmission differential, used to match the yarn tension adjustment range with the movement stroke of the sinker and retaining ring, achieving precise matching of motion parameters.

[0041] The driven gear 4301 rotates while driving the transmission rod 71 to rotate. Through the transmission of the first transmission gear 73, the second transmission gear 74 and the third transmission gear 75, the positioning rod 72 and the positioning gear ring 51 are driven to rotate. The rotation of the positioning gear ring 51 drives the driving block 53 and the adjusting gear 5201 on it. The adjusting gear 5201 drives the lead screw 5202 to adjust the settling plate. The driving block 53 drives the horizontal plate 63 to move, which in turn drives the retaining ring 61 to move.

[0042] Secondly, a double-layer support terry cloth shock-absorbing sock is provided.

[0043] like Figure 10 As shown in this embodiment, a double-layer support terry loop shock-absorbing sock manufacturing device applied to the first aspect above produces double-layer support terry loop shock-absorbing socks, which include a sock body base and a double-layer support terry loop layer on the sole. The sock body is woven from yarn under constant tension, resulting in a smooth and fitted fabric surface; the double-layer support terry layer on the sole is woven from double-layer curled anti-slip yarn and yarn simultaneously. The sole features a zoned structure, with the heel and forefoot areas having a high-loft, shock-absorbing micro-loop structure, and the arch and sides of the sock having a high-tightness, supportive micro-loop structure. The double-layer support terry cloth is shaped by the linkage and follow-up structure, making it upright and sturdy with uniform rebound. It is not easy to collapse or harden under pressure, and can absorb the impact of landing step by step and block the upward transmission of vibration. There is no obvious vibration in the back of the head when wearing it for exercise.

[0044] Double-layered curled anti-slip yarn and sock body yarn participate in the terry knitting process simultaneously. The root of the terry adopts a cross-locking structure and is formed in one piece without loose interlayers. Even after long-term repeated stepping, it can still maintain a three-dimensional vertical support shape and has long-term anti-collapse and fatigue resistance characteristics. The high-loft, shock-absorbing micro-loop loops form a uniform, three-dimensional, breathable cavity inside, balancing cushioning and shock absorption with breathability and heat dissipation; the densely packed, high-support micro-loop loops provide strong support, effectively locking the foot's posture and preventing fatigue from prolonged standing or exercise.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
