Abstract
Description
Technical Field
[0001] The utility model relates to the field of glove knitting machines, in particular to a density triangle linkage regulating 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 summary, ordinary knitting glove machines or knitting flat knitting machines need to adjust or control multiple density triangles before or during knitting. The existing density triangle adjustment methods are mainly manual rotating cams and motor controlled cams, and each density triangle is controlled separately. The latest existing glove machines use bidirectional knitting. For example, a single knitting head can knit gloves on the left or right side of the head, so a head has two sets of mesh devices. If the previous adjustment method is still used, manual single adjustment is time-consuming and labor-intensive, and the consistency of density tightness is poor, which will also lead to different densities during the knitting process of the same glove.
[0005] In the prior patent 2023235369266, the applicant submitted a dual-density linkage adjustment device for a bidirectional knitting glove machine, which "adjusts the slider to push the action arm to swing, so that the left and right relatively symmetrically arranged action arms swing at the same time, thereby changing the position of the corresponding density triangle."
[0006] However, the above structure is still relatively complicated. Therefore, the inventor conducted further research and developed a density triangle linkage adjustment device, which resulted in the present case. Utility Model Content
[0007] The utility model aims to provide a density triangle linkage adjustment device, which can more conveniently adjust the left and right density triangles.
[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0009] A density triangle linkage adjustment device, comprising:
[0010] The first density connecting rod and the second density connecting rod, one end of the first density connecting rod and the second density connecting rod are connected to their respective density triangles, and the other ends are both arranged on the density adjusting rod, a slider is arranged in the middle of the density adjusting rod, and the bottom end of the slider is in contact with the side of the cam through a compression spring; an adjustment block is arranged on one side of the density adjusting rod, and the adjustment block can be adjusted up and down relative to the density adjusting rod, and the adjustment block acts on the first density connecting rod or the second density connecting rod.
[0011] Compared with the prior application, in the technical solution of the present application, the overall up and down movement of the density adjustment rod is adjusted by rotating the cam to determine the weaving density, and the height consistency between the two density triangles is achieved by fine-tuning the height of the adjustment block.
[0012] Furthermore, the slider is located in the fixing seat, and the density adjustment rod passes through the fixing seat.
[0013] Furthermore, the slide block is provided with a groove, and a compression spring is arranged in the groove. One end of the compression spring is acted upon by a positioning pin on the fixing seat, and the other end of the compression spring is acted upon by the slide block.
[0014] Furthermore, the outer contour of the cam is a comma structure, and the bottom of the slider protrudes downward to form an arc-shaped protrusion.
[0015] Reducing the contact area between the slider and the cam can reduce friction.
[0016] Furthermore, the first density connecting rod, the second density connecting rod and their corresponding density triangles are respectively located on two sides of the housing.
[0017] Furthermore, the adjusting block is fixed on the density adjusting rod through an eccentric shaft bolt.
[0018] After adopting the above scheme, the utility model has the following advantages compared with the prior art:
[0019] Compared with the density triangle synchronous adjustment mechanism in the existing design, its structure itself is simpler, the adjustment function can be achieved with fewer parts, and the structure is stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Description of symbols
[0024] The first density connecting rod 11, the second density connecting rod 12, the density adjusting rod 2,
[0025] Adjustment block 21, slider 22, cam 3, compression spring 4, fixing seat 5, positioning pin 51,
[0026] Housing 6. DETAILED DESCRIPTION
[0027] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0028] like Figure 1 , 2 As shown, a density triangle linkage adjustment device includes a first density connecting rod 11 and a second density connecting rod 12 arranged on the left and right sides of the casing 6. On the back side of the casing 6 shown in the figure, a first density triangle and a second density triangle are arranged, which correspond to their respective density connecting rods.
[0029] A density adjusting rod 2 is arranged below the first density connecting rod 11 and the second density connecting rod 12. As shown in the figure, an adjusting block 21 is arranged on the right side of the density adjusting rod 2. The adjusting block 21 is fixed by an eccentric shaft bolt and can move up and down relative to the density adjusting rod 2. That is, the density adjusting rod 2 is used to adjust the weaving density of the density triangle through the density connecting rod, and the adjusting block 21 is used to adjust the consistency of the density triangles on both sides.
[0030] The density adjustment rod 2 is adjusted up and down by the drive of the cam 3. Figure 2 As shown:
[0031] The middle of the density adjustment rod 2 is a slider 22 structure, the bottom of the slider 22 is an arc-shaped protrusion, and below the protrusion is a special-shaped cam 3. The rotation of the cam 3 can change the relative height of the slider 22. At the same time, a compression spring 4 is arranged in the slide groove of the slider 22, so that the slider 22 can contact the cam 3 in real time.
[0032] The upper end of the compression spring 4 is pressed by a positioning pin 51, and the positioning pin 51 is arranged on the fixing seat 5. Figure 1 As shown, the middle part can be used for the density connecting rod to pass through.
[0033] By turning the knob on the other side of the housing 6, the cam 3 is rotated, thereby changing the relative height of the slider 22, thereby changing the relative height of the density triangle, and thus changing the knitting density. The consistency of the density triangles on both sides is fine-tuned by the adjustment block 21. Compared with the existing design or the applicant's previous design, this structure has the advantage of being simpler in structure.
[0034] 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.
