Please refer to fig. 1 to fig. 3. The invention provides an embroidery tufting machine which is used for processing yarns 11 and comprises a needle plate 16, a plurality of embroidery needle devices 18, a yarn feeding device 17, a hook knife 9 and a straight knife 10. The needle board 16 is movably disposed in both the first direction and the second direction. Each embroidery needle device 18 is movably arranged in a first direction, each embroidery needle device 18 comprises a needle bar 6 and an embroidery needle 8, and the embroidery needle 8 is detachably arranged in the needle bar 6. The yarn feeding device 17 is used to feed the yarn 11 to the embroidery needle 8. The hook knife 9 and the straight knife 10 are both arranged on one side of the needle plate 16, and the embroidery needle device 18 and the yarn feeding device 17 are both arranged on the other side of the needle plate 16. Wherein the first direction is perpendicular to the plane of the needle board 16 and the second direction is parallel to the plane of the needle board 16. The plane of the needle board 16 refers to the plane perpendicular to the plane of the needle board shown in fig. 1 and passing through the line a.

The first direction movement in this embodiment means an up-down movement, the needle plate 16 being movable in the first direction means that the needle plate 16 is movable up and down, the needle plate 16 being movable in the second direction means that the needle plate 16 is movable left and right, and each embroidery needle device 18 being movable in the first direction means that each embroidery needle device 18 is movable up and down.

The invention relates to a working method of an embroidery tufting machine, which comprises the following steps: the base fabric is placed on a needle plate 16, a yarn feeding device 17 feeds the yarn 11 into an embroidery needle 8, the embroidery needle 8 drives the yarn 11 to move downwards, the embroidery needle 8 descends to feed the yarn 11, the hook withdrawing knife 9 and the straight knife 10 retreat, the embroidery needle 8 descends to the lowest point, the hook withdrawing knife 9 and the straight knife 10 retreat, the embroidery needle 8 ascends, the hook withdrawing knife 9 advances to hook the yarn 11, and the yarn 11 is looped. When the yarn 11 makes one turn, the straight knife 10 cuts the yarn 11 on the hook knife 9. The base fabric can move left and right only by cutting one circle without leaving a loop, so that the needle can be controlled to be inserted at the position needing embroidery. Embroidery needle 8 is detachably arranged in needle bar 6, the up-and-down movement of embroidery needle 8 is controlled by needle bar 6, and embroidery needle 8 is convenient to replace when being broken due to detachable design.

The existing tufting machine uses row needles to mechanically plant the pile on the base fabric, thereby producing the loop pile or cut pile product, and the row needles move up and down simultaneously in the pile planting process, thereby being incapable of controlling each embroidery needle device, and having output but not delicate. The existing embroidery machine works for a single needle, and has low yield but is exquisite. The embroidery tufting machine of the invention is provided with a plurality of embroidery needle devices 18, each embroidery needle device 18 can be movably arranged in a first direction, free single needles of the embroidery machine are controlled to be arranged together, fixed needle arrangement of the tufting machine is changed into free up-and-down movement of each needle, and the advantages of the embroidery machine and the tufting machine are combined, thereby having both yield and exquisite patterns. And the base fabric moves left and right along with the needle plate 16 when the embroidery needle moves up and down and the needle plate 16 moves left and right, and the embroidery needle 8 can reach each position of the base fabric and carry out embroidery. At the same time, the needle board 16 can be moved up and down, so that the height of the tufts in the final product can be adjusted to suit different tufting requirements.

However, the tension of the yarn 11 in the embroidery tufting machine has a large influence on the quality of the product. Therefore, the embroidery tufting method often further includes a yarn 11 tension adjusting step, the yarn 11 tension adjusting step is located before the yarn feeding step, and the yarn 11 tension adjusting step is used for adjusting the tension of the fed yarn 11 so that the hook knife 9 avoids thread retention. When the tension of the yarn 11 fed is larger or smaller than the yarn clamping force of the base fabric, troubles such as yarn breakage occur.
