Description

TECHNICAL FIELD

[0001] The utility model relates to the field of glove knitting machine, especially to a glove knitting machine lifting needle guard triangle structure. BACKGROUND

[0002] The basic structure of the computer glove knitting machine is that front and rear needle beds are arranged between left and right bases, movable knitting needles are arranged in needle grooves of the needle beds, a triangle base plate is arranged on a split type front and rear machine head, and the triangle base plate moves horizontally with the machine head; various triangles are arranged on the triangle base plate, and the knitting needles (combination needles) are interacted through the needle butts of the triangles to perform needle selection, needle lifting and needle clearing actions to complete various knitting functions.

[0003] The existing computer glove knitting machine generally connects the front and rear machine heads through a machine head connecting device and is driven by a driving device to realize synchronous movement of the front and rear machine heads.

[0004] However, the front and rear machine heads of this type of glove knitting machine are in an idle state during half of the process in one round trip, and do not perform glove knitting, so more and more enterprises begin to develop glove knitting machines capable of simultaneously knitting the front and rear machine heads.

[0005] The applicant has applied for several patents for double-sided knitting, and in this process, the applicant finds that the knitting needle butts have a tendency to deviate from the upward knitting track because the knitting needle butts intervene shallowly between the triangles during the lifting needle knitting process, and simply arranging a guard triangle above the knitting needle butts will affect the needle track during full needle knitting (also known as normal knitting).

[0006] Therefore, the inventor further researches and develops a glove knitting machine lifting needle guard triangle structure, and the present case is generated. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims to provide a glove knitting machine lifting needle guard triangle structure, which can ensure good operation of the lifting needle and normal operation of the full needle knitting during the back-and-forth knitting process.

[0008] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0009] A glove knitting machine lifting needle guard triangle structure comprises

[0010] A triangle base plate, the middle part of the triangle base plate is an upper middle mountain triangle and a lower middle mountain triangle, the two sides of the upper middle mountain triangle are density triangles, and the two sides of the lower middle mountain triangle are needle lifting triangles; an active guard triangle capable of extending and retracting relative to the triangle base plate is arranged above the upper middle mountain triangle corresponding to the needle lifting triangle.

[0011] When normal (full eye) knitting, the lower needle butt of the knitting needle is lifted from the low position of the lifting triangle, and moves along the knitting channel between the upper and lower center mountain triangles, the movable guard triangle on the side of the lifting triangle does not affect the lifting of the knitting needle, and the movable guard triangle on the other side is pressed into the triangle base plate by the upper needle butt;

[0012] When eyelet knitting, the lower needle butt of the knitting needle is lifted from the low position of the lifting triangle, and moves along the knitting channel between the upper and lower center mountain triangles, the movable guard triangle on the side of the lifting triangle does not affect the lifting of the knitting needle, and the movable guard triangle on the other side is pressed into the triangle base plate by the upper needle butt;

[0013] Further, the movable guard triangle is a passive telescopic structure, which is retracted into the triangle base plate when subjected to the pressure of the knitting needle.

[0014] The pressure of the knitting needle here includes the force given by the needle butt.

[0015] Further, the movable guard triangle includes at least one slope.

[0016] When full eye knitting, the needle butt of the knitting needle slides over the slope and presses the movable guard triangle into the triangle base plate.

[0017] Further, the top of the lifting triangle corresponds to the starting point of the slope of the movable guard triangle.

[0018] Whether eyelet knitting or full eye knitting needs to pass through the top of the lifting triangle, and after that, full eye knitting passes through the knitting channel between the upper and lower center mountain triangles, and eyelet knitting slides over the surface of the lower center mountain triangle.

[0019] Further, the side of the movable guard triangle is also provided with a fixed guard triangle.

[0020] The fixed guard triangle is located on both sides of the triangle base plate, and also plays a role in protecting the needle from moving upward.

[0021] Further, the back of the movable guard triangle is provided with a reset spring.

[0022] The telescopic movement of the movable guard triangle is realized through the reset spring.

[0023] After the above scheme is adopted, the present application has the following advantages compared with the prior art:

[0024] Both the upward movement of the knitting needle during eyelet knitting and the influence of full eye knitting can be ensured. BRIEF DESCRIPTION OF DRAWINGS

[0031] The utility model will be further described below in combination with the drawings and specific embodiments.

[0032] As Figure 1 shown, a glove machine lifting needle guard cam structure, including cam plate 1, the middle part of cam plate 1 is upper and lower cam plate 3, 4, the two sides of upper and lower cam plate 3 are density cam, and the two sides of lower cam plate 4 are needle lifting cam 6;The above-mentioned cam is the basic structure of glove machine cam, that is, whether full-eye knitting or lifting-eye knitting, all needles are lifted from needle lifting cam, and the difference lies in that when full-eye knitting, the lower segment needle butt of needle moves from the knitting channel between upper and lower cam plate, and when lifting-eye knitting, the lower segment needle butt of needle 7 slides from the surface of lower cam plate (also the dotted line shown in Figure 1 ).

[0033] The main innovation point of the embodiment is that the movable needle guard cam 2 is arranged at the position corresponding to the upper segment needle butt of needle 7 on the two sides of needle lifting cam, and the movable needle guard cam 2 is arranged in a mode of being able to extend and retract relative to cam plate 1, and it is a passive structure, that is, the movable needle guard cam 2 enters cam plate 1 when being pressed, and restores the extended state when not being pressed.

[0034] Among them, considering the movement track of the upper segment needle butt of needle, the movable needle guard cam 2 is provided with slope 21 on the section facing the needle butt of needle, and the slope 21 can make the upper segment needle butt of needle moving from the side to slide on the movable needle guard cam 2 and press it into cam plate 1;That is, taking the angle in the drawing as a reference, the slopes are all located on the inner side of movable needle guard cam 2, and the outer side of movable needle guard cam 2 is provided with fixed needle guard cam 5, and the fixed needle guard cam 5 can also play the role of movable needle guard cam, but the position arranged by it will not interfere with the needle when full-eye knitting, so it is not necessary to be arranged in a movable mode.

[0035] The position of the slope in cam plate 1 is referenced to the vertex of needle lifting cam, as Figure 1 shown, the lower segment needle butt of needle on the left side is located at the vertex of the left needle lifting cam, and the upper segment needle butt of needle is at the starting point of movable needle guard cam 2.

[0036] Since the existing glove knitting machine has realized double-side simultaneous knitting, when the triangular bottom plate 1 of the embodiment is adopted, the relative positions of the two sides are staggered during the operation of the front and rear triangular bottom plates 1, and the structures are basically the same, as shown in Figure 2 . Figure 2 The arrow in the figure indicates the relative movement direction of the knitting needles, and the positions of the knitting needles in the figure are all the positions passed during full-gauge knitting, so the movable guard cam 2 can be pressed into the triangular bottom plate 1 in the movement direction.

[0037] The above is only a specific embodiment of the utility model, meanwhile, the words such as "upper, lower, left, right, middle" and the like involved in the utility model are only used for reference, not absolute limitation, and any non-substantial change made by using the utility model should belong to the behavior of infringing the protection range of the utility model.
