Description

Technical Field

[0001] The utility model relates to the field of glove knitting machines, in particular to a bidirectional asynchronous knitting cam device. Background Art

[0002] There are basically only two types of conventional glove knitting machines on the market. The first type only has the forward needle raising function, and its reverse needle raising is only used for sealing. In the forward needle raising process, the running track of the needle pin is: first rise and fall along the track surface of the elastic needle raising triangle, then rise to the highest point along the track surface of the forward needle raising triangle, and then fall along the track to the bottom of the forward density triangle to complete a unidirectional knitting that first weaves the elastic and then the yarn.

[0003] The second type: It has both forward and reverse needle casting functions. This type of knitting glove machine is called jacquard glove machine or computer flat knitting machine in the industry. If reverse needle casting is performed after forward needle casting in the same knitting row, the running trajectory of the needle pin is: after passing through the bottom of the elastic density triangle, it also moves through the bottom of the reverse density triangle. This method can achieve reverse needle casting, but it causes serious interference to the entry of the elastic thread, increasing the difficulty of controlling the forward and reverse density triangles.

[0004] In the prior application "CN116623353A" (reference document 1), a cam device capable of switching between single-sided knitting, tuck knitting and bidirectional synchronous knitting was designed. However, since the cam device is only provided with an elastic cam on one side (its Figure 1 , 4 Therefore, when the rubber band is knitted, the knitting efficiency is low, and the rubber band needle channel uses the density triangle on the right side, so it is necessary to adopt the control of the linkage between the right density triangle and the rubber band triangle, and its control structure is relatively complicated.

[0005] Therefore, the inventor conducted further research on this and developed a bidirectional asynchronous weaving triangle device, which resulted in the present invention. Utility Model Content

[0006] The utility model aims to provide a bidirectional asynchronous knitting cam device, which can improve the knitting efficiency of rubber bands and simplify the transmission structure.

[0007] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A bidirectional asynchronous knitting triangle device, comprising:

[0009] A triangular base plate, an upper Zhongshan triangle and a lower Zhongshan triangle are arranged on one side of the triangular base plate, density triangles are arranged on both sides of the upper Zhongshan triangle, elastic auxiliary triangles are arranged on the sides of the density triangles, and elastic triangles are arranged below the elastic auxiliary triangles; wherein the position of the elastic auxiliary triangles relative to the triangular base plate is fixed, the elastic triangles can be extended and retracted relative to the triangular base plate, and an elastic needle passage is formed by the elastic auxiliary triangles and the elastic triangles.

[0010] Since the needle trajectory is different during normal knitting and rubber band knitting, if the design method as in Comparative Document 1 is adopted, the density triangle and the rubber band guide triangle on the right side need to form a rubber band needle path, and the position of the density triangle is different during normal knitting and rubber band knitting, so the active position of the density triangle needs to be strictly controlled; and the technical scheme of the utility model, the needle path for rubber band knitting is formed by the rubber band auxiliary triangle, and rubber band triangles are provided on both sides, so that the rubber band can be started in the back and forth process; the above-mentioned structure on the front and rear triangle bottom plates is consistent.

[0011] Furthermore, the density triangle can move up and down relative to the elastic auxiliary triangle.

[0012] The up and down here can also be understood as "high and low positions" relative to the rubber auxiliary triangle. Generally, during normal weaving, the bottom of the density triangle is lower than the rubber auxiliary triangle. When rubber weaving is performed, the density triangle retreats upward.

[0013] Furthermore, a needle passage is provided on the top of the elastic auxiliary triangle.

[0014] Furthermore, the top of the rubber band auxiliary triangle is a limiting protrusion, and a groove is arranged below the limiting protrusion, and the groove is the needle moving channel.

[0015] The limiting protrusion can stabilize and limit the needle movement of the upper needle heel.

[0016] Furthermore, a pressing triangle is also provided on the side of the elastic auxiliary triangle.

[0017] According to the difference between the front and rear triangle bottom plates, the setting positions of the pressing cam are different, one is relatively on the left side and the other is relatively on the right side. However, during operation, the pressing cams are on the same side because the front and rear triangle bottom plates are arranged facing each other.

[0018] Furthermore, a needle triangle is set on each side of the lower Zhongshan triangle.

[0019] Furthermore, the rising action of the density triangle is achieved by pushing the pendulum rod upward, and the falling action is achieved by resetting the tension spring.

[0020] Furthermore, one end of the tension spring is connected to the density triangle seat of the density triangle, and the other end is connected to the triangle bottom plate.

[0021] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0022] The needle trajectory of the elastic knitting is determined by the elastic auxiliary triangle, and the control method is simpler. The elastic triangles on both sides control the starting needle of the elastic knitting, and the knitting efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] A bidirectional asynchronous knitting cam device, comprising a first cam base plate 1 ( Figure 1 , Figure 2 )、Second triangular base plate 2( Figure 3 , Figure 4), the two cam bottom plates are both provided with an upper Zhongshan cam (101, 201), a lower Zhongshan cam (102, 202), a left density cam (103, 203), a right density cam (104, 204), a left elastic auxiliary cam (105, 205), a right elastic auxiliary cam (106, 206), a left elastic cam (107, 207), a right elastic cam (108, 208), a left needle raising cam (109, 209), a right needle raising cam (110, 210), and a needle pressing cam (111, 211). Since the cam device moves back and forth relative to the needle bed during knitting, the distribution of the cams on the cam bottom plate is symmetrical, that is, the first cam bottom plate is symmetrical. The distribution of the plate 1 and the second triangular bottom plate 2 is that a left density triangle (103, 203) and a right density triangle (104, 204) are arranged on both sides of the upper Zhongshan triangle (101, 201), a left rubber auxiliary triangle (105, 205) is arranged on the side of the left density triangle, and a right rubber auxiliary triangle (106, 206) is arranged on the side of the right density triangle, and a left rubber triangle (107, 207) and a right rubber triangle (108, 208) are arranged below the corresponding rubber auxiliary triangle; wherein the position of the rubber auxiliary triangle relative to the triangular bottom plate is fixed and unchanged, the rubber triangle can be extended and retracted relative to the triangular bottom plate, and the rubber auxiliary triangle and the rubber triangle form a needle path when the rubber is knitted.

[0034] A lower Zhongshan triangle (102, 202) is arranged below the upper Zhongshan triangle (101, 201), a left needle triangle (109, 209) and a right needle triangle (110, 210) are arranged on both sides of the lower Zhongshan triangle, and a pressing triangle (111, 211) is arranged on the side of the elastic auxiliary triangle. Figure 3 ), one relatively on the right ( Figure 1 ), but during operation, since the front and rear triangular bottom plates are arranged facing each other, the pressing cams are on the same side.

[0035] In terms of the setting of the triangle structure, the difference between this embodiment and the comparative document 1 is that, in addition to the different settings of the above-mentioned rubber auxiliary triangle and the rubber triangle, the tops of the left rubber auxiliary triangle (105, 205) and the right rubber auxiliary triangle (106, 206) are also provided with respective left limiting protrusions (1051, 2051) and right limiting protrusions (1061, 2061), and below the limiting protrusions is a groove, which can be used to limit the needle movement channel of the upper needle heel.

[0036] As for the driving part of the triangle, the main difference from the comparative document 1 is that the right sliding seat and the rubber seat of the comparative document 1 are connected by a tension spring, and the rubber triangle is linked to the inclined surface of the pressing block of the density triangle. Figure 2 , Figure 4 As shown, one end of the density tension spring (112, 212) is connected to the density triangle seat (113, 213) of the density triangle, and the other end is connected to the triangle bottom plate, that is, the density triangle does not need to be linked with the rubber triangle. The rise of the density triangle on the two triangle bottom plates is driven by the swing rod with multiple legs, and the downward trend of the density triangle is provided by the tension spring, which is consistent with the comparative document 1.
