Description

Technical Field

[0001] This utility model relates to the field of jacquard machine technology, and specifically to a multi-functional jacquard machine with a raised foot. Background Technology

[0002] Existing jacquard machines achieve the jacquard effect by controlling the lower jacquard pieces through a lower needle cylinder and a lower needle selector. However, this type of jacquard machine cannot adjust the density of the woven fabric, resulting in a limited variety of fabrics that cannot meet consumer needs.

[0003] Therefore, based on the aforementioned shortcomings of existing jacquard machines, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-functional jacquard machine that addresses the shortcomings of existing technologies. This multi-functional jacquard machine solves the defects of existing jacquard machines, such as the inability to adjust the density of the fabric.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] This multi-functional jacquard knitting machine includes an upper needle plate, a lower needle cylinder, a rotating frame, and a lower needle track seat. The lower needle cylinder is equipped with multiple lower needles, which are fitted with a lower needle track. The lower needle track is mounted on the lower needle track seat. The lower end of each lower needle is fitted with a lower center needle, and the lower end of the lower center needle is fitted with a lower jacquard piece. A lower needle selector is fitted to the side of the lower jacquard piece. The lower needle track is equipped with a lower needle density motor, which is mounted on the lower needle track seat and drives the lower needle track to rise and fall.

[0007] Furthermore, multiple upper knitting needles are mounted on the upper surface of the needle plate, and these needles cooperate with the upper needle track. An upper needle selector is mounted above the needle plate, and multiple upper jacquard pieces are mounted on the upper end of the needle plate, each cooperating with the upper needle selector. The front end of each upper jacquard piece is engaged with an upper knitting needle. This enables a double-sided jacquard effect.

[0008] Furthermore, the rotating frame is equipped with an upper needle fixing seat, and the upper needle selector is fixed on the upper needle fixing seat, making installation very convenient.

[0009] Furthermore, the bottom of the upper needle holder is equipped with an upper needle track, making installation very convenient.

[0010] Furthermore, each of the upper jacquard pieces is fitted with an upper center needle at its front end. The front end of the upper center needle engages with the upper knitting needle. The upper jacquard piece controls the upper center needle, thereby controlling the upper knitting needle.

[0011] Furthermore, the upper needle track is equipped with an upper needle density motor, which is mounted on the upper needle fixing seat. The upper needle density motor drives the upper needle track to move laterally, which can control the length of the yarn hooked by the upper needle.

[0012] Furthermore, the lower needle density motor drives the screw to rotate and the lower needle track moves up and down along the screw, or the lower needle density motor drives the gear to rotate and the lower needle track meshes with the gear through a rack and pinion, both of which can achieve the lower needle density motor driving the lower needle track to move up and down, thereby changing the length of the yarn hooked by the lower needle.

[0013] Furthermore, the rotating frame is equipped with a color-changing head, which can achieve a color-changing effect.

[0014] Furthermore, the upper needle density motor drives the screw to rotate and the upper needle track moves along the screw, or the upper needle density motor drives the gear to rotate and the upper needle track moves through a structure of rack and pinion meshing, thereby changing the length of the yarn hooked by the upper needle.

[0015] The beneficial effects of this utility model are as follows: by controlling the rotation angle of the rotor of the lower needle density motor through program control, the lower needle density motor can control the movement of the lower needle track to rise or fall, thereby changing the length of the yarn pulled by the lower needle and achieving the adjustment of the fabric density.
