Description

Technical Field

[0001] This utility model relates to the field of cashmere sweater knitting, and in particular to a cashmere sweater knitting device with switchable knitting density. Background Technology

[0002] Cashmere sweater knitting is a process that uses animal hair such as wool or cashmere as raw materials to form loops of yarn through knitting technology and interlock them to form a fabric. Its core lies in the precise control of knitting density through the coordinated adjustment of equipment parameters, yarn characteristics, and structure, which in turn affects the appearance, feel, and performance of the fabric.

[0003] A search revealed a tension adjustment device for a cashmere sweater knitting machine with switchable knitting density, disclosed in Chinese Patent No. CN 215560964 U. This device includes a worktable, a support plate fixedly mounted on one side of the worktable surface, a material roll on one side of the support plate, an adjustment mechanism on the right side of the support plate, a support column on the side of the adjustment mechanism away from the support plate, a twisting block fixedly connected to the top of the support column, and a winding roller on the right side of the worktable. In this invention, the tension adjustment device for a cashmere sweater knitting machine with switchable knitting density uses a third motor to move a threaded rod that drives a guide plate, thereby changing the knitting angle of the yarn on the guide plate. A smaller knitting angle results in a denser knitting density, while a larger angle results in a looser knitting density. During the process of the guide plate moving and changing the knitting angle of the yarn, the tension of the yarn is also adjusted simultaneously.

[0004] However, the aforementioned tension adjustment device for cashmere sweater knitting machines with switchable knitting density can adjust the tension and angle of multiple cashmere yarns simultaneously when adjusting the knitting density of cashmere sweaters, but it cannot adjust the tension and angle of each cashmere yarn individually, thus having certain limitations.

[0005] Therefore, it is essential to invent a cashmere sweater knitting device with switchable knitting density. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides a cashmere sweater knitting device with switchable knitting density. The technical solution adopted is as follows: a cashmere sweater knitting device with switchable knitting density includes a main motor and a rotating disk, wherein: the main motor is fixedly installed on a support, the output end of the main motor is detachably connected to the rotating disk coaxially, and a plurality of yarn tension adjusters for adjusting yarn are uniformly fixedly installed on the other side of the rotating disk.

[0007] The support includes a fixed plate, and the surface of the fixed plate is uniformly provided with a plurality of yarn routing cavities corresponding to the yarn tension regulators.

[0008] The outer circumferential surface of the fixed plate is provided with at least one fixing lug.

[0009] A spindle hole with a keyway is provided through the center of the surface of the rotating disk. The spindle hole is fixedly connected to the output end of the main motor with a flat key.

[0010] The yarn tension regulator includes an auxiliary motor and a tension arm. The auxiliary motor is fixedly mounted on a rotating disk. The output end of the auxiliary motor is fixedly connected to one end of the tension arm, and the other end of the tension arm has a yarn limiting hole.

[0011] The tension arm has a keyed secondary shaft hole at one end connected to the secondary motor. The secondary shaft hole is fixedly connected to the output end of the secondary motor with a flat key.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] The overall design of this utility model not only allows for simultaneous adjustment of the tension and weaving angle of multiple yarns, but also enables individual adjustment of the tension and weaving angle of each yarn, making the whole system more convenient and flexible in use.

[0022] Example

[0023] Reference Figure 1-3 A cashmere sweater knitting device with switchable knitting density includes a main motor 2 and a rotating disk 3. The main motor 2 is fixedly mounted on a support, and the output end of the main motor 2 is coaxially and detachably connected to the rotating disk 3 so that the main motor 2 drives the rotating disk 3 to simultaneously adjust the tension and knitting angle of multiple yarns 11 by each yarn tension regulator. Several yarn tension regulators for adjusting yarns 11 are evenly fixedly mounted on the other side of the rotating disk 3 so that the tension and knitting angle of each yarn 11 can be adjusted individually by the yarn tension regulators.

[0024] Specifically, the support includes a fixed plate 1, and the surface of the fixed plate 1 is evenly provided with a plurality of yarn feeding cavities 6 corresponding to the yarn tension regulator, so that the yarn 11 can pass through the fixed plate 1 through the yarn feeding cavities 6.

[0025] Specifically, the outer circumferential surface of the fixed plate 1 is provided with at least one fixing lug 7 so that the fixed plate 1 can be installed in the required position by the fixing lug 7 and the bolts.

[0026] Specifically, a spindle hole 9 with a keyway is provided through the center of the surface of the rotating disk 3. The spindle hole 9 is fixedly connected to the output end of the main motor 2 with a flat key so that the rotating disk 3 and the main motor 2 can be disassembled and assembled later.

[0027] Specifically, the yarn tension regulator includes an auxiliary motor 4 and a tension arm 5. The auxiliary motor 4 is fixedly mounted on the rotating disk 3. The output end of the auxiliary motor 4 is fixedly connected to one end of the tension arm 5 so that the auxiliary motor 4 drives the tension arm 5 to rotate, thereby applying pressure to the yarn 11 and adjusting the weaving angle of the yarn 11. The other end of the tension arm 5 is provided with a yarn limiting hole 8 so as to limit the yarn 11 through the yarn limiting hole 8 and ensure the stability between the yarn 11 and the tension arm 5.

[0028] Specifically, the end of the tension arm 5 connected to the auxiliary motor 4 is provided with a keyway secondary shaft hole 10. The secondary shaft hole 10 is fixedly connected to the output end of the auxiliary motor 4 with a flat key, so that the tension arm 5 and the auxiliary motor 4 can be disassembled and assembled separately.

[0029] Tension arm 5 is made of polytetrafluoroethylene (PTFE, Teflon).

[0030] The coefficient of friction is extremely low (0.04 in static mode and 0.01 in dynamic mode), and the yarn sliding resistance is close to zero.

[0031] It is chemically inert, resistant to acids, alkalis, and solvents, and is suitable for processing special yarns (such as flame-retardant yarns and conductive yarns).

[0032] It has excellent self-lubricating properties, reducing wear without the need for additional lubricant.

[0033] In this embodiment, both the main motor 2 and the auxiliary motor 4 are controlled by external controllers, such as external microcontrollers, PLCs, etc.

[0034] like Figure 1 As shown, allow yarn 11 to pass through yarn routing cavity 6 and yarn limiting hole 8;

[0035] When it is necessary to keep all yarns 11 at the same tension, the main motor 2 can drive the rotating disk 3 to rotate each yarn tension regulator, so that the tension and weaving angle of multiple yarns 11 can be adjusted synchronously.

[0036] When it is necessary to adjust the weaving angle and tension of each yarn 11 individually, simply drive the tension arm 5 to rotate via the auxiliary motor 4, thereby applying pressure to the yarn 11 and adjusting the weaving angle of the yarn 11.

[0037] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
