At least two head assembly modules 21 are detachably connected by fasteners to form an integral head assembly module assembly structure. The head assembly module assembly structure is located in front of the housing assembly 20, and a color changing guide rail assembly 23 is arranged between the head assembly module assembly structure and the housing assembly 20. When changing color, the head assembly module combined structure is driven by the color changing box and slides along the color changing guide rail assembly 23, and after the color changing is finished, one set head assembly module 21 is matched with the shell assembly to carry out the ironing piece corresponding to the color material belt (specification).
Refer to the chinese patent application No. 2020101521463, previously filed by the applicant. The machine head assembly module comprises a machine head shell and a sheet feeding roller wheel assembly 212 arranged on the machine head shell, the sheet feeding roller wheel assembly comprises a driving roller and a driven roller, the driving roller is arranged on a driving roller shaft, and the driving roller and the driven roller are matched to convey the material belt. The shell assembly comprises a shell and a sheet feeding motor arranged on the shell, and the sheet feeding motor drives the driving roller to rotate through a sheet feeding transmission mechanism. The film feeding transmission mechanism comprises a film feeding driving gear and a film feeding driven gear which are meshed with each other, the film feeding driven gear is connected with the driving roller, and the film feeding driven gear and the driving roller synchronously rotate.
The mode that send a driving gear and send a driven gear meshing is adopted to carry out the transmission, and the back is changed the look and is accomplished, and the piece driven gear that send that does not work is with sending a driving gear and not meshing, and these send a driven gear to can produce rotatoryly because of the vibrations of machine operation to lead to changing the look in-process, send a driving gear and send a driven gear dislocation, can not smoothly mesh, cause the damage of gear or other some aspects.
Therefore, in order to solve the problems, a sheet feeding driven gear self-locking mechanism for locking the sheet feeding driven gear which does not work after color changing can be further arranged, the sheet feeding driven gear self-locking mechanism comprises a self-locking ejector rod which can be clamped into a tooth groove of the sheet feeding driven gear, so that the sheet feeding driven gear cannot rotate due to vibration of machine operation, and the sheet feeding driving gear and the sheet feeding driven gear can be accurately meshed and driven in the color changing process.
The self-buckling ejector rod is a cylinder and cannot be well meshed with the tooth grooves of the driven gear for feeding the sheets, so that the end of the self-buckling ejector rod is provided with a trapezoidal head in order to adapt to the size and the shape of the tooth grooves of the driven gear for feeding the sheets, and the trapezoidal head is clamped into the tooth grooves of the driven gear for feeding the sheets.
In order to realize the purpose of automatic operation of the self-buckling ejector rod, namely, in the working process of the machine head assembly module before color changing, the self-buckling ejector rod is separated from the tooth groove of the driven piece feeding gear, the meshing transmission of the driven piece feeding gear and the driving piece feeding gear is ensured, after the color changing is finished, the machine head assembly module does not work, and the self-buckling ejector rod can be clamped into the tooth groove of the driven piece feeding gear. Send piece driven gear from knot mechanism still has following technical characteristic, further including the self-locking fixed block that has the activity hole promptly, from detaining ejector pin swing joint in the activity hole, from detaining the ejector pin and being connected with its card of drive and going into the self-locking reset spring who sends piece driven gear tooth's socket to and the drive is from detaining the drive assembly that the ejector pin deviates from sending piece driven gear tooth's socket when trading the look.
