A double-knitting machine feed ring adjusting device

Abstract

This utility model relates to a yarn feed adjustment device for a double-sided knitting machine, comprising a central core, a double-sided plate mounted on the outside of the central core, and a double-sided needle plate located below the double-sided plate. Multiple yarn feed support arms arranged in a circular array are fixedly mounted on the upper side of the central core. A yarn feed ring is tunably mounted on one side of each support arm. A stepped protrusion is machined at a specific inner position of the yarn feed ring to accommodate an alignment block. The alignment block has screw holes for mounting stop adjustment screws. Since the yarn feed support arms are fixed to the central core, the two stop adjustment screws are rotated to adjust their positions, thereby opposing and restraining the front and rear sides of the yarn feed support arms, thus limiting the position of the yarn feed ring and the yarn feed nozzle. Furthermore, adjusting the length of the two stop adjustment screws causes the yarn feed ring and the yarn feed nozzle to rotate circumferentially, thereby adjusting the position of the yarn feed ring. This method is simple, effective, and quick to use.

Description

Technical Field

[0001] This utility model relates to a yarn feeder adjustment device for a double-sided knitting machine, specifically within the field of circular knitting machine technology. Background Technology

[0002] During the circular knitting process, the position of the yarn feeder needs to be adjusted in order to make the fabric meet the requirements. Usually, the yarn feeder is locked at the bottom of the yarn feeder ring and needs to be aligned with the upper needle plate. However, most of the existing yarn feeder rings are fixed on the circular knitting machine, which makes it inconvenient to adjust the position of the yarn feeder during use. Therefore, our company has proposed an improved yarn feeder ring adjustment device for double-sided knitting machines. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a yarn feed adjustment device for a double-sided knitting machine to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a double-sided knitting machine yarn feed adjustment device, including a center core, a double-sided plate installed on the outside of the center core, and a double-sided needle plate located on the lower side of the double-sided plate. Multiple yarn feed support arms arranged in a circular array are fixedly installed on the upper side of the center core, and a yarn feed ring is adjusted and installed on one side of the yarn feed support arm. A yarn feed nozzle is installed on the lower side of the yarn feed ring, and the yarn feed nozzle corresponds to one side of the double-sided needle plate. The yarn feeding ring is provided with an arc-shaped groove, and a screw is screwed into the end of the yarn feeding ring support arm. The screw passes through the arc-shaped groove from top to bottom and is locked onto the yarn feeding ring support arm. Alignment blocks are installed on the corresponding yarn feeding rings on the front and rear sides of the end of the yarn feeding ring support arm. The two alignment blocks are longitudinally locked with anti-adjustment screws, and the ends of the two anti-adjustment screws abut against the front and rear sides of the yarn feeding ring support arm.

[0005] A further improvement is that a fixing screw is vertically installed through the first end of the yarn feeding ring support arm, and the yarn feeding ring support arm is locked to the core by the fixing screw.

[0006] A further improvement is that an L-shaped bottom rod is fixedly provided on the lower side of the yarn feeding ring support arm, and the end of the L-shaped bottom rod is fixedly connected to the lower side of the end of the yarn feeding ring support arm.

[0007] A further improvement is that a support screw is rotatably mounted at the end of the L-shaped base rod, and the bottom of the support screw is locked to the double-sided upper plate thread.

[0008] A further improvement is that the inner ring of the yarn feeding ring is provided with a stepped protrusion, and the arc-shaped groove and the alignment block are both provided on the stepped protrusion, with the arc-shaped groove located between the two alignment blocks.

[0009] Compared with the prior art, the present invention has the following advantages: This invention features a stepped protrusion on the inner side of the yarn feeding ring, allowing for the installation of an alignment block. The alignment block has screw holes for mounting stop adjustment screws. Since the yarn feeding ring support arm is fixed to the core, adjusting the position of the two stop adjustment screws by rotating them allows them to press against the front and rear sides of the yarn feeding ring support arm, thus limiting the position of the yarn feeding ring and the yarn feeding nozzle. Furthermore, adjusting the length of the two stop adjustment screws causes the yarn feeding ring and the yarn feeding nozzle to rotate circumferentially, thereby adjusting the position of the yarn feeding ring. This method is simple, effective, and quick to use. In addition, by fixing an L-shaped bottom rod to the underside of the yarn feeding ring support arm to form an integral structure, the overall structural strength is improved. One end of the L-shaped bottom rod is connected to the double-sided upper plate through a support screw, which can further support the yarn feeding ring support arm and improve the support force and stability of the yarn feeding ring support arm for the yarn feeding ring and the yarn feeding nozzle.

[0011] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0012] Please see Figures 1-3This utility model provides a technical solution for a double-sided knitting machine yarn feeder adjustment device: It includes a center core 1, a double-sided upper plate 101 installed on the outside of the center core 1, and a double-sided needle plate 2 located below the double-sided upper plate 101. Multiple yarn feeder arms 3 arranged in a circular array are fixedly installed on the upper side of the center core 1. A yarn feeder 4 is tunably installed on one side of each yarn feeder arm 3. A yarn feeder nozzle 5 is installed on the lower side of the yarn feeder 4, corresponding to one side of the double-sided needle plate 2. An arc-shaped groove 43 is provided on the yarn feeder 4, and a screw 30 is screwed onto the end of each yarn feeder arm 3. The screw 30 passes through the arc-shaped groove 43 from top to bottom and is locked onto the yarn feeder arm 3. Therefore, when the screw 30 is not tightened, the rotation of the yarn feeder 4 allows the screw 30 to be positioned within the arc-shaped groove 43. Within the range of 3, the corresponding yarn feeding rings 4 on the front and rear sides of the end of the yarn feeding ring support arm 3 are equipped with alignment blocks 41, and the two alignment blocks 41 are longitudinally locked with stop adjustment screws 42. The ends of the two stop adjustment screws 42 abut against the front and rear sides of the yarn feeding ring support arm 3, thereby limiting the position of the yarn feeding ring 4 and the yarn feeding nozzle 5. A fixing screw 6 is vertically installed at the left end of the yarn feeding ring support arm 3, and the yarn feeding ring support arm 3 is locked to the core 1 by the fixing screw 6. An L-shaped bottom rod 31 is fixedly installed on the lower side of the yarn feeding ring support arm 3. The end of the L-shaped bottom rod 31 is fixedly connected to the lower side of the end of the yarn feeding ring support arm 3, thereby improving the structural strength of the yarn feeding ring support arm 3 to support the weight of the yarn feeding ring support arm 3, the yarn feeding ring 4 and the yarn feeding nozzle 5. Furthermore, a support screw 32 is rotatably installed at the end of the L-shaped bottom rod 31. The bottom of the support screw 32 is threadedly locked to the double-sided upper plate 101. The support screw 32 can increase the support force at the end of the yarn feeding ring support arm 3, and prevent it from collapsing and deforming due to excessive gravity.

[0013] Preferably, the inner ring of the yarn feeding ring 4 is provided with a stepped protrusion 44, and the arc-shaped groove 43 and the alignment block 41 are both provided on the stepped protrusion 44. The arc-shaped groove 43 is located between the two alignment blocks 41. This can avoid affecting the installation of the yarn feeding ring 4 and the yarn feeding nozzle 5, and facilitates connection with the yarn feeding ring support arm 3.

[0014] When using, such as Figure 2As shown, by simply adjusting the screw-in distance of the two opposing anti-adjustment screws 42 on the alignment block 41, the front and rear sides of the yarn feeding ring support arm 3 can be held in place. At this time, the yarn feeding ring 4 and the yarn feeding nozzle 5 are both limited and fixed. When it is necessary to adjust the rotation of the yarn feeding ring 4 and the yarn feeding nozzle 5, the anti-adjustment screw 42 on one side is unscrewed so that the end of the anti-adjustment screw 42 is disengaged from the side of the yarn feeding ring support arm 3. Then, the screw 30 is loosened. At this time, the yarn feeding ring 4 and the yarn feeding nozzle 5 can rotate within the range of the side where the anti-adjustment screw 42 is disengaged from the side of the yarn feeding ring support arm 3. During rotation, the screw 30 can move along the arc-shaped groove 43. After rotation adjustment, the yarn feeding ring support arm 3 is tightened back to the arc-shaped groove 43 by screw 30. Then, the two anti-adjustment screws 42 are rotated to hold the yarn feeding ring support arm 3 in place. It is simple, convenient, quick and effective to use.
