Description

Technical Field

[0001] The utility model relates to the field of glove knitting, in particular to a triangular device used for bidirectional elastic knitting of a glove machine. Background Art

[0002] There are two types of glove knitting machines on the market, which are suitable for unidirectional knitting and bidirectional knitting of gloves. The basic working principle of unidirectional knitting is:

[0003] When knitting the main body of the cylindrical part of the glove, when the needle guide head moves from left to right, the needle guide triangle device on the rear needle guide head pushes up the knitting needle on the rear needle bed and eats the yarn in a yarn mouth to complete a knitting action; correspondingly, when the needle guide head moves from right to left, the needle guide triangle device in the front needle guide head pushes up the knitting needle on the front needle bed and relays the yarn in the same yarn mouth to complete another knitting action. Therefore, the needle guide head completes a reciprocating action from left to right and then back to left, which is called completing a knitting row. In this way, the yarn is knitted in a single spiral manner.

[0004] On this basis, in order to increase work efficiency, the inventor has previously applied for a Chinese invention patent with patent number CN202210035315.4, disclosing "a knitting glove machine front and rear heads synchronous yarn feeding and knitting mechanism and knitting method thereof". In this application, it is explained that the front and rear needle guide heads can respectively feed two yarns at the same time during the working process. In the same knitting horizontal row, by arranging the two needle guide heads in a staggered or side-by-side manner and reasonably adjusting the amplitude of the knitting needle descent, positive and reverse needle raising can be achieved (positive needle raising generally refers to that when the rear needle guide head moves from left to right, only the needle guide triangle device on the rear needle guide head pushes up the knitting needles on the rear needle bed, and the needle guide triangle device on the right needle guide head pushes up the knitting needles on the rear needle bed). When moving to the left, only the needle guide triangle device on the front needle guide head pushes up the knitting needles on the front needle bed, and the reverse needle raising means that when the rear needle guide head moves from left to right, the needle guide triangle device on the front needle guide head can also push up the knitting needles on the front needle bed, and when moving from right to left, the needle guide triangle device on the rear needle guide head can also push up the knitting needles on the rear needle bed). This can not only meet the requirements of sewing the fingertips and finger seams of the knitted gloves together, but also meet the requirements of not sewing together when knitting all other knitting horizontal rows, thereby achieving the knitting speed being nearly doubled without increasing the movement speed of the needle guide head, and greatly improving the production capacity. The two yarns in this equipment are woven together in a cross double helix manner.

[0005] When knitting the cuff of a glove (also known as elastic knitting in the industry), in order to solve the problem that ordinary knitting gloves or flat knitting machines cannot normally achieve both reverse knitting and elastic knitting in the same knitting row, in CN114908468A (reference document 1), a needle guide triangle device suitable for bidirectional knitting of the rib part of a glove is applied to solve the problem existing in the prior art. However, the technical solution of reference document 1, as shown in its Figures 5 and 6, during the back-and-forth movement of the machine head, elastic knitting is only achieved in the state of Figure 5, while in the state of Figure 6, the elastic triangle does not participate in the knitting, and the efficiency of elastic knitting is low.

[0006] Therefore, the inventor conducted further research and developed a cam device for bidirectional elastic band knitting of a glove machine, which resulted in the present invention. Utility Model Content

[0007] The utility model aims to provide a cam device for bidirectional elastic band knitting of a glove machine. After adopting the above scheme, the efficiency of elastic band knitting can be improved in the bidirectional knitting mode of the glove machine.

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

[0009] A cam device for bidirectional elastic band knitting of a glove machine comprises a first bottom plate and a second bottom plate, wherein:

[0010] The first upper Zhongshan cam and the first lower Zhongshan cam are arranged in the middle of the first bottom plate, a first density cam is arranged on each side of the first upper Zhongshan cam, a first left needle raising cam and a first right needle raising cam are arranged on both sides of the first lower Zhongshan cam, a first left elastic cam with a needle raising direction opposite to that of the first left needle raising cam is arranged on the left side of the first left needle raising cam, and a first right elastic cam with a needle raising direction opposite to that of the first right needle raising cam is arranged on the right side of the first right needle raising cam; the first left elastic cam and the first right elastic cam have the ability to expand and contract relative to the first cam bottom plate;

[0011] The triangles on the second bottom plate are arranged in a mirror image with the triangles on the first bottom plate.

[0012] The needle casting direction here refers to the direction in which the butt of the knitting needle moves from bottom to top along the hypotenuse of the needle casting triangle or the elastic triangle and participates in weaving; referring to the principle explanation of comparative document 1, by arranging retractable left and right elastic triangles on the left and right sides of the triangle bottom plate, the machine head can carry out elastic weaving during the back and forth movement, that is, when the left elastic triangle is working, the right elastic triangle is retracted and does not work, and when the right elastic triangle is working, the left elastic triangle is retracted and does not work, thereby improving the efficiency of elastic weaving.

[0013] Furthermore, a first left rubber auxiliary triangle and a first right rubber auxiliary triangle are respectively arranged above the first left rubber triangle and the first right rubber triangle;

[0014] The rib auxiliary triangle on the second bottom plate is arranged in a mirror image with the rib auxiliary triangle on the first bottom plate.

[0015] An elastic braided channel is formed between the elastic triangle and the elastic auxiliary triangle.

[0016] Further, the first density triangle is located between the first elastic auxiliary triangle and the first upper middle mountain triangle.

[0017] The first rubber auxiliary cam here includes a first left rubber auxiliary cam and a first right rubber auxiliary cam.

[0018] Furthermore, a first pressing needle cam is arranged on the right side of the first right elastic auxiliary cam, and the first pressing needle cam can move up and down relative to the first bottom plate.

[0019] Furthermore, the first left needle-casting triangle and the first right needle-casting triangle both include a needle-casting bevel and an avoidance bevel, and the needle-casting bevel and the avoidance bevel are arranged on both sides.

[0020] Furthermore, both sides of the first left elastic triangle and the first right elastic triangle are provided with a needle raising bevel and an avoidance bevel.

[0021] The side where the bevel of the needle is located is the aforementioned needle direction.

[0022] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0023] During the double-sided knitting process of the gloves, the elastic band can be knitted when the machine head moves back and forth, thus improving the knitting efficiency compared to the previous process that could only knit elastic bands in a single stroke.

[0034] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] When the glove machine is knitting, the triangular base plate (machine head) moves back and forth and left and right relative to the fixed needle bed. Therefore, in the diagram, the left row of the machine head is equivalent to the right row of knitting needles, and the right row of the machine head is equivalent to the left row of knitting needles.

[0036] In this embodiment, the triangles on the first triangular base plate 1 and the second triangular base plate are arranged in a mirror image (refer to Figure 1 , Figure 3 ), so the movement of the first triangular base plate 1 is described as the main object.

[0037] like Figure 1 As shown, when the first triangle bottom plate 1 moves to the left, the needle trajectory (dashed part) is to the right, and the butt of the knitting needle first passes under the first left elastic auxiliary triangle 161, passes through the surface of the avoidance slope of the first left elastic triangle 151 (not involved in the work), and reaches the starting point of the needle bevel of the first left needle raising triangle 141 under the first density triangle 13 on the left, and rises and falls along the needle running channel between the first upper Zhongshan triangle 11 and the first lower Zhongshan triangle 12, and drops to the starting point of the needle bevel at the first right elastic triangle 152 due to the restriction of the first density triangle on the right. At this time, the first right elastic triangle 152 is in working state, so the needle butt can move along the needle running channel between the first right elastic triangle 152 and the first right elastic auxiliary triangle 162 to perform elastic weaving.

[0038] like Figure 2 As shown, when the first triangle bottom plate 1 moves to the right, the needle trajectory is to the left, that is, the needle butt first passes under the first right elastic auxiliary triangle 162, passes through the surface of the avoidance slope of the first right elastic triangle 152, and reaches the starting point of the needle bevel of the first right needle raising triangle 142 under the first density triangle 13 on the right side, and then rises and falls along the needle movement channel between the first upper Zhongshan triangle 11 and the first lower Zhongshan triangle 12, and then drops to the starting point of the needle bevel of the first left elastic triangle 151 to the limit of the first density triangle on the left side. At this time, the first left elastic triangle 151 is in working state, so the needle butt moves along the needle movement channel between the first left elastic triangle 151 and the first left elastic auxiliary triangle 161 to perform elastic weaving.

[0039] A first needle pressing cam 17 is also provided on the right side of the first right elastic auxiliary cam 162, which is used to assist the needle pressing when knitting the fingers of the gloves. It is a commonly used cam when knitting gloves and will not be described in detail here.

[0040] The structure and needle movement process of each cam on the second cam base plate 2 are consistent with those of the first cam base plate 1. The two cam base plates are arranged opposite to each other on the needle bed of the glove machine. Therefore, their structure, working principle and process are the same as those of the first cam base plate 1, which will not be elaborated here.

[0041] The cast-on cam, elastic cam, density cam and presser cam are commonly used cams when knitting a glove machine. Their functions and structures are basically the same. Their coordination and relative position relationship are the key to distinguishing the functions of each glove machine.

[0042] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
