Description

Technical Field

[0001] The invention belongs to the field of textiles, in particular to a composite four-needle bed upper plate. Background Art

[0002] The mountain plate is a component on the head of a computer flat knitting machine. Currently, the computer flat knitting machines on the market are double-needle bed weft knitting machines. A pair of mountain plates are provided at the lower end of the flat knitting machine head. The two mountain plates have the same structure and are composed of a motherboard, an aluminum cover, a mountain corner assembly, a needle cleaning mountain corner, a needle lifting mountain corner, and a drive assembly. The motherboard has two mounting surfaces. The mountain corner assembly and the drive assembly are respectively mounted on the two surfaces of the motherboard. The drive assembly can drive the mountain corner assembly to move. The aluminum cover is mounted on the drive assembly to reinforce the drive assembly. Each of the above mountain corner assemblies consists of a limiting mountain corner I, two limiting mountain corners II, two degree mountain corners, and a needle turning mountain corner. The limiting mountain corner I and the limiting mountain corner II are both V-shaped, and the opening installation directions are opposite. The limiting mountain corner I There is a gap between the two limiting mountain corners II, and the motherboard at the gap is used to install the degree mountain corner. The bevels on both sides of the degree mountain corner are respectively fitted with the bevels of the limiting mountain corner I and the limiting mountain corner II. The degree mountain corner moves up and down along the bevels under the drive of the driving assembly. The above-mentioned turning needle mountain corner is located below the limiting mountain corner I, and the gap between the turning needle mountain corner and the limiting mountain corner forms a stitch track. At the same time, a separate stitch track is also provided on the turning needle mountain corner, and a needle cleaning mountain corner and a needle lifting mountain corner are provided on the motherboard below each limiting mountain corner II. The above-mentioned mountain plate is installed at the lower part of the machine head. When the machine head moves back and forth on the needle bed, the pins of the knitting needles will first contact the front end of the moving direction of the needle cleaning corner and then contact other corners. The front end of the needle cleaning corner and the needle lifting corner can control the spacing between the pins of the knitting needles and the mountain plate, thereby controlling the pins to move along different tracks on the corner assembly after entering the corner assembly. The back end of the needle movement direction can reset the pins to the position when entering the corner assembly, so that the pins contact the rear end of the needle cleaning corner again, so that the pins enter the next action arrangement under the control of the rear end of the needle cleaning corner and the needle lifting corner. The pins move along different tracks on the corner assembly, which can force the knitting needles to move up and down regularly in the needle groove of the needle bed. The two mountain plates cooperate with each other to complete the turning and connecting of the corresponding knitting needles on the front and rear needle beds, so as to achieve the purpose of knitting. However, the knitting efficiency of this double needle bed knitting structure is low, the compactness of the knitting is not high, and the turning needle corner structure in the mountain plate is not reasonable enough, which cannot meet the growing needs in the flat knitting machine industry. Summary of the invention

[0005] Furthermore, a slope sloping outward and downward is provided at the needle insertion opening. The above design facilitates needle insertion.

[0006] Furthermore, the stitch track I is M-shaped, the stitch track II is a horizontal track, and a triangular protrusion flush with the pin-turning corner is provided on the stitch track II, and the sharp corner of the triangular protrusion is opposite to the center of the stitch track I and a gap is left to form a connecting end. The above design structure is the most reasonable.

[0007] Furthermore, the mountain corner components are multiple groups, and one of the limiting mountain corners II of two adjacent mountain corner components is shared. The above design can realize the purpose of needle turning and needle connection of single system and double system according to the needs.

[0008] Furthermore, the composite four-needle bed upper plate also includes a horizontal stitch track III, which is located at the turning corner of the stitch track II, and both ends of the stitch track III are provided with an upward slope I, and the stitch track III and the stitch track I are respectively arranged at the two ends of the stitch track II. The above design not only provides more needle movement methods, but also makes it difficult to derail when flat stitching.

[0009] Compared with the prior art, the advantages of the present invention are: after the upper mountain plate is installed on the machine head and is at the upper end of the existing mountain plate, the flat knitting machine can achieve the purpose of having no empty needle positions when knitting with full needles, and can realize the purpose of needle transfer and needle connection of single system and double system according to needs, thereby improving knitting efficiency and enhancing the compactness of knitting.
