Description

Technical Field

[0001] The utility model relates to the technical field of jacquard machines, in particular to a high-yield single-color transfer rib jacquard machine. Background Art

[0002] The transfer rib jacquard knitting machine is a common type of circular knitting machine. The core component of the circular knitting machine is the weaving unit composed of triangles. In existing transfer rib jacquard knitting machines, the upper triangle assembly includes two sets of upper weaving tracks and a set of connecting loops, while the lower triangle assembly includes two sets of lower weaving tracks and a set of transfer loop tracks. The number of weaving units that can be arranged in a circular knitting machine is positively correlated with the equipment's output. In the traditional layout, the circular path occupied by each weaving unit is long, which restricts the equipment's output. Therefore, how to optimize and shorten the weaving unit path length to increase output became the problem to be solved in this case. Utility Model Content

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a high-yield single-color transfer rib jacquard machine which increases production by shortening the path length of a weaving unit.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows: a high-yield single-color transfer rib jacquard machine, comprising a plurality of arranged weaving units, wherein the weaving units include an upper cam assembly and a lower cam assembly;

[0005] The upper cam assembly includes a single-side knitting track, an upper knitting track, and a loop connection track arranged in sequence; the lower cam assembly includes a flat needle track, a lower knitting track, and a loop transfer track arranged in sequence; the loop transfer track includes a loop transfer ascending section, a lateral shifting section, a first descending section, and a last descending section arranged in sequence;

[0006] The upper weaving track and the lower weaving track are positioned correspondingly and form a jacquard weaving path;

[0007] The ring connection track corresponds to the ring transfer ascending section, the lateral transfer section, and the first descending section in the ring transfer track to form a ring transfer connection path;

[0008] The single-side knitting track corresponds to the last descending section of the transfer track in the previous knitting unit and the flat needle track position of the current knitting unit to form an upper single-side knitting path.

[0009] Furthermore, the ratio of the trajectory lengths of the first descending section and the last descending section is 1:(0.5-2).

[0010] Furthermore, the single-side weaving track is provided with a first yarn feeding point, and the upper weaving track is provided with a second yarn feeding point.

[0011] Furthermore, it also includes a first needle selector and a second needle selector, the first needle selector corresponds to a first needle selection point, and the second needle selector corresponds to a second needle selection point. The lower weaving trajectory includes a first rising section and a second rising section. The starting end of the first rising section corresponds to the first needle selection point, and the starting end of the second rising section corresponds to the second needle selection point.

[0012] Furthermore, it also includes a third needle selector, and the third needle selector is correspondingly formed with a third needle selection point, and the starting end of the transfer rising section corresponds to the third needle selection point.

[0013] Furthermore, it also includes a needle gate unit, which is inserted between two adjacent groups of weaving units.

[0014] From the above description of the present invention, it can be seen that compared with the prior art, the high-yield single-color transfer rib jacquard machine provided by the present invention has the following advantages: by redesigning and arranging the upper triangle component and the lower triangle component in the weaving unit, the head and tail positions of the two adjacent groups of weaving units form a stacked design, thereby realizing the arrangement of more groups of weaving units on the circular machine of the same size, thereby improving the output of the equipment.

[0017] The present invention is further described below through specific implementation methods.

[0018] Reference Figure 1 As shown, a high-yield single-color transfer rib jacquard machine includes several groups of arranged weaving units.

[0019] The knitting unit includes an upper cam assembly 1 and a lower cam assembly 2. The upper cam assembly 1 includes a single-side knitting track 11, an upper knitting track 12, and a stitch connection track 13, which are arranged in sequence. The lower cam assembly 2 includes a flat stitch track 21, a lower knitting track 22, and a stitch transfer track 23, which are arranged in sequence. The stitch transfer track 23 includes a stitch transfer ascending section 231, a transverse section 232, a first descending section 233, and a last descending section 234, which are arranged in sequence. The length ratio of the first descending section 233 to the last descending section 234 is 1:(0.5-2), preferably 1:1.

[0020] The upper weaving track 12 corresponds to the lower weaving track 22 and forms a jacquard weaving path; the connecting track 13 corresponds to the transfer ascending section 231, the lateral section 232, and the first descending section 233 in the transfer track 23 to form a transfer connecting track; the unilateral weaving track 11 corresponds to the last descending section 234 of the transfer track 23 in the previous weaving unit and the flat needle track 21 of the current weaving unit to form an upper unilateral weaving path.

[0021] The single-side braiding track 11 is provided with a first yarn feeding point 111 , and the upper braiding track 12 is provided with a second yarn feeding point 121 .

[0022] The lower knitting track 22 further includes a first needle selector 3, a second needle selector 4, and a third needle selector 5. The first needle selector 3 is formed with a first needle selection point 31, the second needle selector 4 is formed with a second needle selection point 41, and the third needle selector 5 is formed with a third needle selection point 51. The lower knitting track 22 includes a first ascending section 221 and a second ascending section 222. The starting end of the first ascending section 221 corresponds to the first needle selection point 31, the starting end of the second ascending section 222 corresponds to the second needle selection point 41, and the starting end of the transfer ascending section 231 corresponds to the third needle selection point 51.

[0023] The first and second needle selectors 3 and 4 coordinate to select jacquard knitting patterns in plain, half, and full stitches. The third needle selector 5 controls whether to perform stitch transfer and stitch joining. This equipment is suitable for the production of single-color transfer rib products.

[0024] The machine also includes a needle door unit 6, which is inserted between two adjacent weaving units. The needle door unit 6 is used for convenient maintenance.

[0025] The design principle of this high-yield single-color transfer rib jacquard machine is as follows:

[0026] In the present application, a group of weaving units has two weaving paths and one transfer and connection path, wherein the two weaving paths include a first upper unilateral weaving path and a second jacquard weaving path. The upper unilateral weaving path only requires the upper needle to pass through the upper weaving track 12 to perform the yarn-eating action, so the lower triangle component 2 corresponding to the upper unilateral weaving path only needs to set the flat needle track 21 to keep the lower needle at a height position that does not affect the knitting of the upper needle. At the same time, due to the last section in the transfer and connection path, the lower knitting needle has been lowered to a height position that does not affect the knitting of the upper needle at the last section descending section 234, so in this weaving unit, the last section descending section 234 is correspondingly set below the upper weaving track 12 in the next weaving unit. Based on this setting method, the track length of the flat needle track 21 will be shortened. That is, the head and tail positions of the adjacent front and rear groups of weaving units form a stacked design, so that more groups of weaving units can be set on the same size circular machine, thereby increasing the output of the equipment.

[0027] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
