Description

Technical Field

[0001] This utility model relates to a mechanism, and more particularly to a mechanism for stabilizing the needle groove of a flat knitting machine, which belongs to the field of flat knitting machine technology. Background Technology

[0002] The needle assembly is driven by the base plate, which is in the form of a flat cam. When it moves along the Y direction, it drives the needle assembly to move along the X direction in the needle groove. At this time, the needle assembly will also bear the Y-direction force brought by the base plate.

[0003] When making fine needles in a flat knitting machine (the needle inserts and needle assembly are thinner due to the large number of needle grooves per inch in the fine needle pointer plate), the needle assembly is subjected to the Y-axis force from the base plate. The thin inserts have poor rigidity and are deformed or the needle groove spacing becomes smaller due to the Y-axis force of the needle assembly. This affects the normal needle output of the needle assembly, increases the risk of missing needles, and affects the overall fabric quality.

[0004] Therefore, it is particularly necessary to provide a stable needle groove spacer mechanism for flat knitting machines with a reasonable structural design, long insert life, normal needle output, and reduced risk of needle leakage. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and provide a knitting flat knitting machine stabilizing needle groove partition mechanism with simple and reasonable structural design, safety and reliability, increased stability of the needle exit section, reduced risk of needle leakage, and improved overall fabric quality.

[0006] The technical solution adopted by this utility model to solve the above problems is as follows: the knitting flat knitting machine has a stabilizing needle groove spacer mechanism, including a needle plate, inserts and a needle assembly. The needle plate has evenly distributed grooves, and multiple inserts are installed in the grooves. The distance between two adjacent inserts forms a needle groove. The needle assembly is placed in the needle groove. The needle assembly consists of a knitting needle, a long needle, a spring needle and a selector needle from front to back. The feature is that it also includes a spacer 1, a spacer 2, a dovetail groove 1 and an insert strip 1. The front section of the insert has a dovetail groove 1, and a spacer 1 is provided at one point of the dovetail groove. A spacer 2 is provided in the groove between the back needle of the long needle and the front end of the spring needle. A trapezoidal insert strip 1 is provided above the spacer 1 and fits against the dovetail groove 1 of the insert to limit the spacer 1 in the vertical direction.

[0007] Preferably, the present invention further includes a filling part and a concave part. The partition is provided with a plurality of evenly distributed filling parts, and the partition without filling parts is provided with a concave part at one end.

[0008] Preferably, the spacer 1 of this invention can be divided into two separate parts, with a gap between the two spacers 1. Preferably, the present invention also includes a steel wire, which is disposed at the upper limit of the tail of the limiting needle.

[0009] Preferably, the present invention also includes a second filling part, wherein a plurality of evenly distributed second filling parts are provided on the second partition, and the plurality of second filling parts cooperate with the needle groove. The second partition is located above the steel wire, and its upper edge does not exceed the upper edge of the insert.

[0010] Preferably, the groove described in this utility model is either a U-shaped groove or a dovetail groove.

[0011] Preferably, the present invention also includes a second insert, wherein a trapezoidal insert is provided above the second partition, and the trapezoidal insert fits into the second dovetail groove so that the second partition is limited in the vertical direction.

[0012] Preferably, both the first and second partitions of this invention are in the form of comb-shaped flat plates.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] Example

[0022] See Figures 1 to 5 In this embodiment, the stabilizing needle groove spacer mechanism of the flat knitting machine includes a needle plate 1, inserts 2, needle group 3, spacer 4, spacer 5, and insert strip 6. The needle plate 1 has evenly distributed grooves, and multiple inserts 2 are installed in the grooves. The distance between two adjacent inserts 2 forms a needle groove. The needle group 3 is placed in the needle groove. The needle group 3 consists of needle 31, long needle 32, spring needle 33, and selector needle 34 from front to back.

[0023] See Figure 2 As shown, the needle assembly is driven by a base plate, which is a planar cam. When the base plate moves along the Y-axis, it drives the needle assembly to move along the X-axis within the needle grooves. At this time, the needle assembly also bears the Y-axis force from the base plate. When making fine needles in a flat knitting machine (fine needles refer to the needle plate with a large number of one-inch needle grooves, resulting in thinner inserts and needle assembly thickness), due to the large number of needle grooves and thin inserts, the needle assembly, when bearing the Y-axis force from the base plate, suffers from poor rigidity due to the thin inserts. This can cause deformation or abnormal conditions such as a smaller needle groove spacing caused by the Y-axis force of the needle assembly, affecting the normal needle output, increasing the risk of missed needles, and affecting the overall fabric quality.

[0024] See Figure 3 To solve this problem, this example adds a spacer 4 at the dovetail groove 21 at the front of the insert 2, and adds a spacer 5 in the groove between the rear needle of the long needle 32 and the front end of the spring needle 33.

[0025] See Figure 4 As shown, the spacer 4 has evenly distributed filling portions 41 on its surface. The width of the filling portions 41 is close to and slightly smaller than the width of the needle groove. The filling portions 41 are evenly fitted into each needle groove, increasing the rigidity of the front part of the insert, making it less prone to deformation, and improving the stability of the knitting needles during various knitting actions. To increase ease of assembly and disassembly, the spacer 4 can be divided into two separate parts with a gap between them. The end of the spacer 4 without the filling portion 41 has a concave portion 42 for inserting disassembly tools. To increase the overall stability of the spacer 4, the spacer 4 can be a single piece, i.e., the spacer 4 has filling portions 41 at both ends. A trapezoidal insert 6 is provided above the spacer 4, which fits against the dovetail groove 21 of the insert, thus limiting the spacer 4 in the vertical direction.

[0026] See Figure 4As shown, the second spacer 5 has evenly distributed filling portions 51, which are tightly fitted to the needle groove. The second spacer 5 is located above the steel wire 23, and its upper edge does not exceed the upper edge of the insert. During installation, a tool is needed to squeeze it into the needle groove to prevent it from shifting up and down. The second spacer 5 increases the rigidity of the middle section of the insert, making it less prone to deformation. The positions of the first spacer 4 and the second spacer 5 are important needle exit sections. Adding spacers at these two positions effectively increases the stability of the needle exit section.

[0027] In this embodiment, the groove can be either a U-shaped groove or a dovetail groove 22-1, depending on the actual situation.

[0028] See Figure 5 As shown, in order to solve Figure 3 The partition 2 5 shown is set in the U-shaped groove. The partition 2 5 is tightly fitted with the needle groove. There is no upper limit to the position, but there is a loosening problem due to uncertain factors. The U-shaped groove is replaced with a dovetail groove 22-1. The steel wire 23 that limits the upper limit of the tail of the long needle 32 is removed. The partition 2 5 is moved down to replace the function of the steel wire 23. A trapezoidal insert 2 7 is set above the partition 2 5. It fits with the dovetail groove 22-1 so that the partition 2 5 is limited in the vertical direction.

[0029] In this embodiment, both the first partition 4 and the second partition 5 are in the form of comb-shaped flat plates.
