Description

Technical Field

[0001] The utility model relates to the technical field of flat knitting machine equipment, in particular to a spring needle locking assembly on a needle plate device. Background Art

[0002] The textile and garment industry is both a traditional industry in my country and an important industry in my country's economic development.

[0003] As an important part of textile products, textile products are deeply loved by consumers for their softness, breathability, and close-fitting wear. With the development of science and technology, computerized flat knitting machines have gradually replaced hand-cranked flat knitting machines with their advantages of fast speed and stable quality. The mountain plate on the head of the computerized flat knitting machine can enable the knitting needles to complete the five basic actions of knitting, tuck, transfer, stitching and non-knitting. Needles need to be selected before weaving to perform different weaving, tuck or non-weaving states. The usual needle selection and needle movement method is achieved through the movement of various triangles installed on the mountain plate. However, traditional computer flat knitting machines require knitting needles to complete tight knitting work. The spring needle is pressed into the needle groove by the pressure plate on the mountain plate, and the long needle is pressed into the needle groove by the spring needle, and the lower heel of the long needle is sunk into the needle groove. This method causes the spring needle to constantly rub against the pressure plate of the mountain plate, which accelerates the wear of the heel of the spring needle under long-term work, thereby greatly increasing production costs. When replacing worn spring needles, the machine needs to be stopped and the mountain plate removed, otherwise the worn spring needle cannot work normally, which is easy to affect the quality of textile products. In addition, since there are a large number of knitting needles in the computer flat knitting machine, workers are required to find worn spring needles with the naked eye, which not only increases the workload and maintenance costs, but also greatly reduces work efficiency.

[0005] To achieve the above-mentioned purpose, the utility model discloses a spring needle locking assembly on a needle plate device, comprising a needle plate and a spring needle, wherein the needle plate is provided with a plurality of insert plates at intervals along the length direction, and needle grooves are formed between the plurality of insert plates, so that the spring needles are slidably inserted in the needle grooves respectively, and a pressure needle opposite to the spring needle is slidably inserted in the lower part of the needle groove, and a pressure needle rear plate heel is provided at the upper end of the pressure needle relative to the spring needle, so that the pressure needle rises under the driving of a mountain plate and passes through the pressure needle rear plate heel to press the spring needle in a pressed state into the needle groove, and when the spring needle rises, the pressure needle is driven to descend by the mountain plate so that the pressure needle rear plate heel of the pressure needle is separated from the spring needle.

[0006] Furthermore, a first spring heel is arranged on the upper part of the spring needle, and a second spring heel is arranged on the upper part of the spring needle below the first spring heel, and the second spring heel has a concave position. When the pressing needle rises, the rear heel of the pressing needle buckles the concave position of the second spring heel and presses the first spring needle in the pressed state into the needle groove.

[0007] Furthermore, the lower part of the insert is provided with a first guide strip inserted into the needle groove, and the front lower part of the pressure needle contacts and cooperates with the first guide strip. The lower part of the insert is also provided with a second guide strip inserted into the needle groove, and the lower part of the pressure needle is provided with a guide groove, and the guide groove slides with the second guide strip.

[0008] Furthermore, the end surfaces of the plurality of inserts are provided with slots on the upper part of the pressure pins, and a limit plate is slidably inserted between the slots.

[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1-Figure 2 As shown, a spring needle locking assembly on a needle plate device includes a needle plate 1, a spring needle 2, a knitting needle 4, a long needle 5, and a needle selection foot 6. The needle plate 1 is provided with a plurality of inserts 11 at intervals along the length direction, and a needle groove 12 is formed between the plurality of inserts, so that the knitting needle 4, the long needle 5, the spring needle 2, and the needle selection foot 6 can be slidably inserted into the needle groove 12 from top to bottom, respectively. In this embodiment, a mountain plate is slidably provided on the needle plate 1, and the mountain plate slides horizontally along the needle plate 1 with a random head, so that the mountain plate is linked to the plurality of spring needles 2, knitting needles 4, long needles 5, and the needle selection foot 6 in the needle groove 12 to perform weaving work. In this embodiment, the connection relationship between the needle plate 1 and the mountain plate, and the linkage relationship between the mountain plate and the plurality of spring needles 2, knitting needles 4, long needles 5, and the needle selection foot 6 are all existing technologies, and will not be repeated here.

[0022] Reference Figure 1-Figure 3 As shown, the upper end of the long needle 5 is embedded in the lower end of the knitting needle 4, the upper part of the spring needle 2 is against the lower part of the long needle 5, the needle selection foot 6 is arranged opposite to the spring needle 2, and the upper part of the spring needle 2 is provided with a first spring heel 21. In this embodiment, the spring needle 2, the knitting needle 4, the long needle 5, and the needle selection foot 6 are the existing technologies. For specific working methods of the spring needle 2, the knitting needle 4, the long needle 5, and the needle selection foot 6, please refer to the Chinese utility model patent, which is a mountain plate with multiple needle channels with publication number CN215404837U, and no repetitive description will be made here.

[0023] Due to the knitting requirements, the first spring heel 21 of the spring needle 2 needs to be pressed into the needle groove 12. Currently, most conventional mountain plates use a retractable pressing plate to support the first spring heel 21 of the spring needle, so that the first spring heel 21 of the spring needle 2 is pressed into the needle groove 12 through the pressing plate, so that the spring needle 2 presses the lower part of the long needle 5 and then presses the lower heel 221 of the long needle 5 into the needle groove 12. However, the mountain plate inevitably generates friction with the first spring heel 21 of the spring needle 2 during movement. Under long-term friction, the first spring heel 21 will cause heat and wear, thereby accelerating the service life of the spring needle and greatly increasing the production cost and maintenance cost.

[0024] Reference Figure 4-Figure 6 As shown, in order to solve the above problems, in this embodiment, a pressing needle 3 opposite to the spring needle 2 is slidably inserted in the lower part of the needle groove 12, and a pressing needle rear butt 31 is arranged at the upper end of the pressing needle 3 relative to the spring needle 2, and a pressing needle lower butt 34 is arranged at the bottom of the pressing needle 3, and the pressing needle lower butt 34 is in triangular contact and cooperation with the bottom plate of the mountain plate, and a pressing needle front butt 35 is arranged on the pressing needle 3, and the pressing needle front butt 35 is in triangular contact and cooperation with the guide needle, and a second spring heel 22 is arranged below the first spring heel 21 at the upper part of the spring needle 2, and a recess 23 is provided on the second spring heel 22, so that the pressing needle rear butt 31 of the pressing needle 3 buckles the second spring heel 22 when it rises, and the spring needle 2 in the pressed state is pressed into the needle groove 12 by the pressing needle 3, so that the first spring heel 21 of the spring needle 2 does not expose the needle groove 12 and rubs against the pressure plate of the mountain plate.

[0025] Reference Figure 4 , Figure 5 As shown, further, the lower part of the insert 11 is provided with a first guide strip 13 and a second guide strip 14 inserted into the needle groove 12, the front lower part of the pressing needle 3 is in contact with the first guide strip 13, and the lower part of the pressing needle 3 is provided with a guide groove 33, the guide groove 33 is slidably matched with the second guide strip 14, and the end faces of several inserts 11 are provided with slots 111 at the upper part of the pressing needle 3, and a limiting plate 112 is slidably inserted between the slots 111, so that the upper and lower ends of the pressing needle 3 can slide up and down along the needle groove 12 under the action of the second guide strip 14 and the limiting plate 112. In this embodiment, the cross-section of the slot 111 is dovetail-shaped, so that the limiting plate 112 can be quickly connected to the needle plate 1, and at the same time, the limiting plate 112 can prevent the upper part of the pressing needle 3 from exposing the needle groove 12, thereby avoiding the pressing needle 3 from colliding with the mountain plate or failing to normally compress the spring needle 2.

[0026] During specific operation, when the spring needle is not involved in the work, the bottom plate triangle of the mountain plate extends out, so that when the bottom plate triangle of the mountain plate passes through the lower pressing needle plate 34 of the pressing needle 3, the pressing needle 3 is lifted up and rises along the needle groove 12 under the action of the bottom plate triangle, so that when the pressing needle 3 rises, the pressing needle rear plate heel 31 is used to buckle the concave position 23 of the second spring plate heel 22, so that the first spring plate heel 21 of the spring needle 2 in the pressed state is pressed into the needle groove 12 under the action of the pressing needle 3, so that the first spring plate heel 21 of the spring needle 2 sinks into the needle groove, so that the mountain plate will not rub against the first spring plate heel of the spring needle during operation.

[0027] When the spring needle is needed to participate in the work, the needle selecting pin is selected by the needle selector of the mountain plate to drive the spring needle to rise. At the same time, when the needle guide triangle of the mountain plate passes through the front needle butt 35 of the pressing needle 3, the pressing needle descends along the needle groove under the action of the needle guide triangle, so that the rear needle butt 31 of the pressing needle 3 is separated from the concave position 23 of the second spring butt 22, so that when the spring needle 2 is reset under the action of its own elasticity, the first spring butt 21 of the spring needle is exposed from the needle groove to participate in the work.

[0028] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical scheme of the utility model should be included in the protection scope of the utility model.
