[0002] A pattern machine, also known as a computer pattern machine or computer embroidery machine, is a highly automated sewing device specially used for embroidering complex and delicate patterns and texts on textiles. The reel-and-roll structure of the pattern machine is a mechanical device for automatically feeding and collecting embroidery fabrics.

[0003] However, the prior art has the following disadvantages when used: the reeling and unreeling structure of the existing pattern machine generally drives the round rod to rotate forward and reversely through a motor to reel in or unreel the fabric, but when the round rod is disassembled and assembled with the reeling and unreeling structure, multiple bolts and nuts need to be repeatedly rotated, which is not conducive to simplifying the work process of the staff and improving work efficiency. In addition, when different sizes of fabrics are required, corresponding round rods are required to cooperate with the reeling and unreeling, but the existing reeling and unreeling structure has a low applicability to round rods of different sizes. Therefore, a reeling and unreeling structure of a pattern machine is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of the existing winding and unwinding structure of the existing pattern machine in the prior art, which generally drives the round rod to rotate forward and reversely through a motor to wind or unwind the cloth, but when the round rod is disassembled and assembled with the winding and unwinding structure, multiple bolts and nuts need to be repeatedly rotated, which is not conducive to simplifying the work process of the staff and improving the work efficiency. In addition, when different sizes of cloth are required, corresponding round rods are required to cooperate with the winding and unwinding, but the existing winding and unwinding structure has a low applicability to round rods of different sizes.
