Description

Technical Field

[0001] This utility model relates to the field of knitting sweater machine technology, and in particular to an interchangeable high-efficiency knitting sweater machine. Background Technology

[0002] With the development of new varieties of chemical fibers and finishing processes, the crispness, wrinkle-free properties, and abrasion resistance of knitted fabrics have been improved. The application of finishing techniques such as napping, brushing, shearing, embossing, and pleating has enriched the variety of knitted products. A knitting machine uses needles to form loops from various raw materials and yarns, which are then interlocked to form knitted fabrics. Knitted fabrics are soft, have good wrinkle resistance and breathability, and possess significant stretch and elasticity, making them comfortable to wear.

[0003] A circular knitting machine is equipped with two sets of yarns: one set is laid down using a warp knitting method, and the other set is laid down using a weft knitting method. The knitting needles combine the two sets of yarns to form loops, creating a knitted fabric. A circular knitting machine is a type of weft knitting equipment used in the textile industry. It achieves high-speed knitting through the cooperation of the cylinder and a cam system, and is suitable for the production of clothing, home textiles, and industrial fabrics. Its core indicators include precision parameters such as needle plate flatness and cylinder roundness.

[0004] A search of existing technology revealed a device called "A High-Precision Sweatshirt Knitting Machine" (publication number CN221940761U). This device uses a sliding rod to move a support plate driven by a threaded block, thereby using a support rod to move a support ring. This allows for adjustment of the support ring's height, facilitating replacement by workers. However, this control method requires worker cooperation and necessitates climbing a ladder for replacement, which still reduces work efficiency. Utility Model Content

[0005] Therefore, it is necessary to address the issue that the control method requires staff to operate and climb ladders for replacement, which still reduces work efficiency. To address this, an interchangeable high-efficiency knitting sweater machine is provided, comprising: a knitting machine body, with multiple support legs fixedly connected to its surface, and a ring frame fixedly connected between adjacent support legs; an interchangeable mechanism, installed on the upper end of the support legs, with its surface extending into the interior of the knitting machine body; wherein the interchangeable mechanism includes a control component installed inside the knitting machine body, the upper end of which is connected to a staggered lifting component, which is installed inside the support legs, with its upper end extending above the support legs.

[0006] In one embodiment, the staggered lifting assembly includes an outer support ring and an inner support ring disposed above the knitting machine body. The inner support ring is located inside the outer support ring. A plurality of first sealing telescopic cylinders are fixedly connected to the lower end of the outer support ring, and a plurality of second sealing telescopic cylinders are fixedly connected to the lower end of the inner support ring. The lower ends of the first sealing telescopic cylinders are embedded in the interior of the support legs, and the second sealing telescopic cylinders are fixedly connected to the inner wall of the ring frame.

[0007] In one embodiment, the control assembly includes two sealed cylinders fixedly connected to the bottom wall of the knitting machine body. A movable rod is provided inside the two sealed cylinders. Both ends of the movable rod penetrate into the interior of the sealed cylinder and are fixedly connected to a piston. The piston is slidably connected to the inner wall of the adjacent sealed cylinder. A connecting sleeve is provided between the two sealed cylinders and is fixedly connected to the surface of the movable rod.

[0008] In one embodiment, the lower end of the second sealing telescopic cylinder is fixedly connected to an inner tube, and multiple inner tubes are arranged in a ring along the central axis of the knitting machine body. The lower end of each inner tube is fixedly connected to a flow equalization chamber. The position of the flow equalization chamber can be appropriately adjusted according to the internal space of the knitting machine body to ensure the normal use of the knitting machine body and to synchronously and matchingly extend and adapt the inner tubes.

[0009] In one embodiment, the lower end of the first sealing telescopic cylinder is fixedly connected to the lower end of an outer connecting pipe, and the lower ends of the plurality of outer connecting pipes are fixedly connected to an annular pipe, the longitudinal section of which is annular.

[0010] In one embodiment, the ends of the two sealing cylinders furthest from the moving rod are respectively fixedly connected to an inner connecting pipe and an outer connecting pipe. The inner connecting pipe is fixedly connected to the lower end of the flow equalization chamber, and the upper end of the outer connecting pipe is fixedly connected to the lower end of the annular pipe. The inner connecting pipe can be arc-shaped to ensure normal movement within the knitting machine. The outer connecting pipe and the sealing cylinders are located below the internal equipment of the knitting machine. Specifically, a partition or embedded mounting bracket can be installed to ensure normal operation of the internal machinery and avoid affecting the knitting machine. Specific adjustments can be made based on actual conditions.

[0011] In one embodiment, an electro-hydraulic actuator is fixedly connected to the bottom wall of the knitting machine body on one side of the movable rod. A connecting plate is fixedly connected to the telescopic end of the electro-hydraulic actuator, and the connecting plate is fixedly connected to the surface of the connecting sleeve.

[0012] Beneficial effects

[0013] The aforementioned interchangeable high-efficiency knitting sweater machine, through its interchangeable mechanism, allows multiple second-sealed telescopic cylinders to lift the internal support ring upwards when liquid is injected into the flow equalization chamber through the connecting inner tube. Liquid inside the annular tube is then input into the other end of the sealed cylinder, causing the first-sealed telescopic cylinder to drive the outer support ring downwards. The outer support ring and the inner support ring are arranged in a concentric circle, achieving synchronous staggered lifting and lowering of the outer and inner support rings. This simplifies the operation steps, reduces the workload of workers, and minimizes the impact on work efficiency.

[0014] The device, through its control components, allows the pistons inside the two sealed cylinders to move synchronously in one direction via a moving rod. This enables the liquid inside the connecting inner tube to be absorbed through the connecting outer tube when the pressure inside the inner tube increases. This allows for a synchronous, staggered lifting and lowering operation of the outer and inner support rings, reducing the workload for workers and minimizing the impact on work efficiency.

[0027] The following is combined Figures 1-4This invention describes an interchangeable, high-efficiency knitting sweater machine.

[0028] In one embodiment, an interchangeable high-efficiency knitting sweater machine includes: a knitting machine body 1, with a plurality of support legs 2 fixedly connected to the surface of the knitting machine body 1, and a ring frame 21 fixedly connected between adjacent support legs 2; an interchangeable mechanism 3, which is installed on the upper end of the support legs 2, and the surface of the interchangeable mechanism 3 extends into the interior of the knitting machine body 1; wherein, the interchangeable mechanism 3 includes an adjustment component 32 installed inside the knitting machine body 1, the upper end of the adjustment component 32 is connected to an interlaced lifting component 31, the interlaced lifting component 31 is installed inside the support legs 2, and the upper end of the interlaced lifting component 31 extends through to the top of the support legs 2;

[0029] It should be noted that the knitting machine body 1 is a circular weft knitting device used in the textile field. It achieves high-speed knitting through the cooperation of the cylinder and the cam system. It is suitable for the production of clothing, home textiles and industrial fabrics. Its core indicators include precision parameters such as the flatness of the needle plate and the roundness of the needle cylinder.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the staggered lifting assembly 31 includes an outer support ring 312 and an inner support ring 316 disposed above the knitting machine body 1. The inner support ring 316 is located inside the outer support ring 312. The lower end of the outer support ring 312 is fixedly connected to a plurality of first sealing telescopic cylinders 311, and the lower end of the inner support ring 316 is fixedly connected to a plurality of second sealing telescopic cylinders 315. The lower end of the first sealing telescopic cylinders 311 is embedded in the interior of the support leg 2, and the second sealing telescopic cylinders 315 are fixedly connected to the inner wall of the ring frame 21.

[0031] The lower end of the second sealing telescopic cylinder 315 is fixedly connected to an inner tube 317. Multiple inner tubes 317 are arranged in a ring along the central axis of the knitting machine body 1. The lower end of the inner tube 317 is fixedly connected to a flow equalization chamber 318. The lower end of the first sealing telescopic cylinder 311 is fixedly connected to the lower end of an outer connecting tube 313. Multiple outer connecting tubes 313 are fixedly connected to an annular tube 314. The longitudinal section of the annular tube 314 is annular.

[0032] In this embodiment, multiple second-sealed telescopic cylinders 315 and multiple first-sealed telescopic cylinders 311 are staggered. When the control component 32 injects liquid into the flow equalization chamber 318, multiple inner pipes 317 are connected to the flow equalization chamber 318, so that the telescopic ends of multiple second-sealed telescopic cylinders 315 simultaneously lift the inner support ring 316 upward. At the same time, the liquid inside the annular pipe 314 is input into the control component 32. Through multiple outer connecting pipes 313, the telescopic ends of multiple first-sealed telescopic cylinders 311 move downward synchronously, so that the outer support ring 312 moves downward accordingly. This makes the outer support ring 312 and the inner support ring 316 form an alternating lifting and lowering mode, thereby reducing the difficulty of changing parts during processing and simplifying processing efficiency.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the control component 32 includes two sealed cylinders 321 fixedly connected to the bottom wall of the knitting machine body 1. The two sealed cylinders 321 are provided with moving rods 323 inside. Both ends of the moving rods 323 pass through the inside of the sealed cylinders 321 and are fixedly connected to pistons 322. The pistons 322 are slidably connected to the inner walls of the adjacent sealed cylinders 321. A connecting sleeve 324 is provided between the two sealed cylinders 321. The connecting sleeve 324 is fixedly connected to the surface of the moving rods 323.

[0034] The ends of the two sealing cylinders 321 away from the moving rod 323 are respectively fixedly connected to the inner tube 328 and the outer tube 327. The inner tube 328 is fixedly connected to the lower end of the flow equalization chamber 318, and the upper end of the outer tube 327 is fixedly connected to the lower end of the annular tube 314. An electro-hydraulic push rod 326 is fixedly connected to the bottom wall of the knitting machine body 1 on one side of the moving rod 323. A connecting plate 325 is fixedly connected to the telescopic end of the electro-hydraulic push rod 326, and the connecting plate 325 is fixedly connected to the surface of the connecting sleeve 324.

[0035] In this embodiment, during use, the electro-hydraulic actuator 326 is driven to cause the connecting plate 325 to move synchronously with the telescopic end of the electro-hydraulic actuator 326. At this time, the connecting plate 325 retracts during movement, and the moving rod 323 moves synchronously inside the two sealing cylinders 321 through the connecting sleeve 324. The pistons 322 at both ends of the moving rod 323 move inside the adjacent sealing cylinders 321, so that the pressure inside one sealing cylinder 321 increases while the pressure inside the other sealing cylinder 321 decreases synchronously. This allows the outer support ring 312 and the inner support ring 316 in the staggered lifting assembly 31 to achieve synchronous control.

[0036] Working principle: The telescopic end of the drive electro-hydraulic actuator 326 drives the connecting plate 325 to move synchronously. When the connecting plate 325 moves, the connecting sleeve 324 drives the moving rod 323 to move synchronously inside the two sealing cylinders 321. The pistons 322 at both ends of the moving rod 323 move inside the adjacent sealing cylinders 321. The pressure inside one sealing cylinder 321 increases, so when the connecting inner tube 328 injects liquid into the flow equalization chamber 318, multiple inner tubes 317 are connected to the flow equalization chamber 318. The telescopic ends of multiple second sealing telescopic cylinders 315 lift the inner support ring 316 to move upward. The outer support ring 312 and the inner support ring 316 achieve synchronous control operation. The liquid inside the annular tube 314 is input into the other sealing cylinder 321. Through the outer connecting tube 313, the telescopic end of the first sealing telescopic cylinder 311 drives the outer support ring 312 to move downward. The outer support ring 312 and the inner support ring 316 form an alternating lifting and lowering mode, which simplifies the processing efficiency.

[0037] It should be noted that the electro-hydraulic actuator 326 and other components mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electro-hydraulic actuator 326 can be powered by an internal power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
