Single-head plain embroidery machine of light structure

Abstract

The invention discloses a single-head plain embroidery machine of a light structure. The machine comprises a rack, a machine head, a color changing mechanism, a plain embroidery shuttle box provided with a thread cutting mechanism and an embroidery frame moving mechanism, the rack comprises two brackets opposite to each other, at least two beams and at least two bottom beams, and each bracket is composed of an upper cross arm, a column and a lower cross arm which are connected in sequence and form a C-shaped structure; the beams are arranged between the upper cross arms of the two brackets, the bottom beams are arranged between the lower cross arms of the two brackets, and the embroidery frame moving mechanism is hoisted below the beams; the shuttle box is arranged on one bottom beam, themachine head and the color changing mechanism are arranged on the beam above the shuttle box, a needle rod frame is arranged on the front portion of the machine head, and the color changing mechanismdrives the needle rod frame to move and switch different needle rods to the positions over the shuttle box, so that color changing is completed. The machine is convenient to move, reduces cost, improves the embroidery efficiency and is suitable for pattern plate making and personalized embroidery; the needle rod switching accuracy is high, the sound is low, the speed is high, the color changing noise is reduced, and the color changing failure rate is reduced.

Description

technical field [0001] The invention relates to the field of flat embroidery machines, in particular to a single-head flat embroidery machine with a portable structure. Background technique [0002] With the continuous development of society, people have higher and higher requirements for the appearance of clothing and fabrics. Flat embroidery machines can directly embroider various beautiful patterns on clothing and fabrics to increase the beauty of clothing and fabrics. Due to the high purchase cost and high operation and maintenance cost of large-scale embroidery machines, small and portable embroidery machines with low operation and maintenance costs can be developed; flat embroidery machines are mostly large-scale gantry-type structures, and miniaturization design is relatively inconvenient. Many technical difficulties need to be solved, so that the existing portable embroidery machine for flat embroidery is improved by expanding the flat embroidery function on the sing...

Problems solved by technology

Due to the high purchase cost and high operation and maintenance cost of large-scale embroidery machines, small and portable embroidery machines with low operation and maintenance costs can be developed; flat embroidery machines are mostly large-scale gantry-type structures, and miniaturization design is relatively inconvenient. Many technical difficulties need to be solved, so that the existing portable embroidery machine for flat embroidery is improved by expanding the flat embroidery function on the single-head cap embroidery machine. The structure is unreasonable and the operation is not stable enough. The operation of the line structure is unstable, and the maintenance failure rate is extremely high! Use a stepping open-loop motor to drive the cam to change the color, and detect the position through the potentiometer. The color changing accuracy is poor, the noise is large, the speed is slow, the potentiometer is easily damaged, it is inconvenient to use, and even often needs to be shut down for maintenance, which greatly increases the production cost.
