Abstract
Description
Technical Field
[0001] This utility model relates to the field of garment machines, and in particular to a needle plate assembly for stable needle output with multiple needle pitches. Background Technology
[0002] In the garment weaving industry, most garment knitting machines (22 needles or more) have a one-alternate-one-needle structure. This means that even-numbered needles on the front needle bed work to knit the front piece, while odd-numbered needles on the back needle bed work to knit the back piece. The remaining empty needles are used for transferring stitches. During a transfer, the loops taken in on the front (or back) needle bed are turned onto the corresponding empty needles on the back (or front) needle bed. After the transfer, the loops are turned back onto the corresponding needles on the front (or back) needle bed.
[0003] In the above-mentioned garment machine, the conventional arrangement of the needles on the needle plate group is still mainly based on equal spacing, that is, the needle spacing between each adjacent needle is the same, while the toothed plate and sinker plate are arranged between the needles in an intermittent manner.
[0004] However, as the needle density on garment machines increases, the width of the toothed plate and sinker plate becomes increasingly limited, leading to their thinning. If the original arrangement of one toothed plate or sinker plate in each needle slot is maintained, the existing thickness of these plates is insufficient to maintain stable needle movement during needle exit, resulting in reduced stability of the garment machine. Utility Model Content
[0005] The purpose of this invention is to provide a needle plate assembly with stable needle output for multiple needle pitches, thereby improving the needle plate assembly of garment machines and enhancing the stability of needle operation in garment machines, especially high-density garment machines.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A needle plate assembly with stable needle delivery across multiple needle spacings, comprising:
[0008] Needle plate;
[0009] Insert A is inserted into the needle plate at equal intervals;
[0010] Insert B is inserted into the needle plate at equal intervals and is staggered with insert A to form needle grooves. The thickness of insert B is greater than that of insert A so that the needle spacing of adjacent needle grooves is inconsistent.
[0011] The knitting needle is slidably positioned in the needle groove;
[0012] A settling plate is installed at the front end of the needle plate and is located within the extended plane of the insert B;
[0013] The toothed plate is installed at the front end of the needle plate and is located in the extension plane of the insert B. The toothed plate and the settling plate are smoothly stacked together, and the inner side of the toothed plate is flush with the inner side of the insert B.
[0014] Preferably, the front end of the toothed plate has a guide portion, the guide portion includes a support plate, the support plate is arranged across two adjacent needle grooves and is flush with the bottom of the protruding needle, and the side end of the support plate is provided with an upwardly extending guide plate, the side of the needle is in contact with the guide plate when it protrudes from the needle groove.
[0015] Preferably, it also includes a needle guard, the lower edge of which extends into the space between two adjacent needle grooves, so that when the needle extends out of the needle groove, the side of the guide plate smoothly presses against the side of the needle.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This solution makes space for the thickening of insert B by making a thin insert A, and then sets the toothed plate and sinker plate in the extension plane of insert B in a stacked form, thereby increasing the stacked thickness of the toothed plate / sinker plate. After the knitting needle extends out of the needle groove, the stacked toothed plate / sinker plate assembly is sufficient to stably guide the knitting needle, which greatly improves the operating stability of the garment machine.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] like Figures 1-7 The illustrated needle plate assembly for stable needle delivery with multiple needle spacing includes a needle plate 6 with several slots. It also includes several inserts A1 and several inserts B2. Inserts A1 are inserted into the slots on the needle plate 6 at equal intervals, while inserts B2 are similarly inserted into the remaining slots on the needle plate at equal intervals. This creates a staggered arrangement of inserts A and B, forming needle grooves for the sliding insertion of knitting needles. It should be noted that the grooves formed by inserts A and B have the same width to allow the use of knitting needles of the same specification and to ensure that the needles are clamped and constrained by inserts A and B when sliding within them.
[0029] It should also be noted that in this design, the thickness of insert B is greater than that of insert A, so that the pin spacing between adjacent pin grooves formed by inserts A and B is inconsistent. Specifically, as follows... Figure 7As shown, starting from the first insert at one end of the needle plate, the needle grooves formed have the same stitch spacing for odd-numbered grooves, while the stitch spacing for even-numbered grooves is also the same, and the stitch spacing between adjacent grooves differs. It should be noted that in this design, the thickness of insert B is greater than that of inserts in conventional high-density garment machines, while the thickness of insert A is less than that of inserts in conventional high-density garment machines, to allow space for insert B. The purpose of making insert B thicker in this design is to ensure sufficient width within the extension plane of insert B for accommodating the overlapping assembly of the toothed plate 3 and the sinker plate 5, and to ensure that the overlapping assembly of the toothed plate and the sinker plate does not interfere with the extension and retraction of the knitting needles. It should be noted that in this design, by stacking the toothed plate and the sinker plate together to increase the thickness of the needle guide component, the combination of the sinker plate and the toothed plate can remain stable when guiding and supporting the side of the needle after the needle extends out of the needle groove. This prevents the needle from twisting and deforming due to its own softness, which would affect the stable operation of the needle. It should also be noted that in this design, in the stacked toothed plate / sinker plate assembly, the toothed plate is located on the inner side, that is, on the side that contacts the needle, to better control and guide the needle.
[0030] Furthermore, as a further improvement to the above embodiment, a U-shaped guide portion is provided at the front end of the toothed plate 3. This guide portion specifically includes a support plate 31 spanning two adjacent needle slots. The support plate is connected to the toothed plate, and its upper surface is flush with the bottom surface of the needle extending out of the needle slot, ensuring that the needle can smoothly slide through the support plate 31. Simultaneously, a vertically raised guide plate 32 is provided at the side end of the support plate. This guide plate forms a channel with the body of the toothed plate to constrain the extending needle. Specifically, when a needle extends from the two needle slots spanned by the support plate, whether it is a left or right needle, its outer surface will be constrained by the toothed plate body or the guide plate, preventing it from sliding out of the support plate 31. It should be noted that this solution replaces the traditional steel wire with a support plate, thus eliminating the need for steel wire holes in the toothed plate and further improving the strength of the toothed plate.
[0031] It should also be noted that, based on the above scheme, a needle guard plate 4 can be added to guide and constrain the inner surface of the protruding needle in conjunction with the toothed plate. Specifically, as shown... Figures 3-5 As shown, the needle guard 4 has a smooth side plate that extends into the space between the two needle grooves spanned by the support plate and aligns with the insert A located between the two needle grooves. This ensures that when the knitting needle extends out of the needle groove, its outer surface smoothly contacts the toothed plate or guide plate, while its inner surface smoothly contacts the needle guard. Specifically, as... Figure 3 , Figure 4As shown, when the needle on the left side of insert A extends, the side of the needle smoothly adheres to surface a of the needle guard, while when the needle on the right side of insert A extends, the side of the needle smoothly adheres to surface b of the needle guard.
[0032] Working principle: This solution provides sufficient space for insert B to be made thicker by making thin insert A, ensuring that the thickness of insert B is greater than the combined thickness of the toothed plate and the sinker plate. Then, the combined toothed plate and sinker plate are placed in the extension plane of insert B. When the needle extends, the combined component of the toothed plate and sinker plate has sufficient thickness to ensure the stability of the needle during movement.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
