The output end of the third cylinder is fixedly connected to the electric hot press seat 601, and the third cylinder and the electric hot press seat 601 are respectively connected to the control system signal. The control system controls the output of the third cylinder so that the third cylinder drives the electric hot press seat 601 to move vertically downward and perform printing. The control system controls the electric hot press seat 601 to heat and print the pattern on the transfer film 5 onto the shoe upper.

[0061] In this embodiment, if Figure 6 As shown, the transmission assembly 1 includes a conveyor belt 102, an active roller 103, a driven roller 104 and a fifth driving structure 105, the fifth driving structure 105 is connected to the control system signal, the fifth driving structure 105 is connected to the active roller 103, the active roller 103 and the driven roller 104 are respectively arranged at both ends of the conveyor belt 102, the fifth driving structure 105 controls the active roller 103 to rotate so that the conveyor belt 102 operates, and the conveyor belt 102 operates to drive the driven roller 104 to rotate, and the fifth driving structure 105 is a motor. A plurality of upper placement positions 101 are arranged on the conveyor belt 102, and the upper placement positions 101 are used to place uppers to be printed or uppers that have been printed.

[0062] Specifically, Figure 1As shown, the control system drives the active roller 103 to rotate by controlling the fifth driving structure 105 to make the conveyor belt 102 run, and after the upper placement position 101 carrying the shoe upper to be printed moves to the right side of the third fixed plate 402, the control system drives the active roller 103 to stop rotating by controlling the fifth driving structure 105, and then the control system controls a negative pressure suction nozzle 301 to execute the first motion state and the second motion state, sucks the shoe upper to be printed from the upper placement position 101, and places the shoe upper to be printed on the printing table 401 located at the loading position, and the printing table 401 carrying the shoe upper to be printed moves to the printing position for printing, and at the same time, the control system drives the active roller 103 to rotate by controlling the fifth driving structure 105 to make the upper placement position 101 on the conveyor belt 102 where the shoe upper to be printed is sucked away moves, and moves to below the negative pressure suction nozzle 301 executing the third motion state, and after the upper placement position 101 carrying the shoe upper to be printed moves to the right side of the third fixed plate 402, the control system drives the active roller 103 to stop rotating by controlling the fifth driving structure 105. The active roller 103 stops rotating, and the printing table 401 carrying the printed upper moves from the embossing position to the loading position. The control system controls one negative pressure suction nozzle 301 to execute the first motion state and the second motion state, and at the same time controls another negative pressure suction nozzle 301 to execute the third motion state. One negative pressure suction nozzle 301 first moves to the upper placement position 101 carrying the upper to be printed, sucks the upper to be printed, and then moves to the upper loading position to put the upper to be printed into the printing table 401. The other negative pressure suction nozzle 301 moves to the upper placement position 101 carrying the upper to be printed, sucks the upper to be printed, and then moves to the upper loading position to put the upper to be printed into the printing table 401. 01 first moves to the top of the printing table 401, sucks the printed shoe upper in the printing table 401, and then moves to the top of the shoe upper placement position 101 without the shoe upper, and places the printed shoe upper on the shoe upper placement position 101. When the two negative pressure suction nozzles 301 have completed the movement state, the control system controls the printing table 401 carrying the shoe upper to be printed to move to the imprinting position for printing, and drives the active roller 103 to rotate by controlling the fifth driving structure 105, so that the conveyor belt 102 runs and performs reciprocating motion.

[0063] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
