[0053] The present invention is a fully automatic printing device, in particular a fully automatic printing device for rubber gloves, which can fully automatically and accurately print on rubber gloves, reduce labor, improve work efficiency, reduce waste of raw materials, and reduce production and processing costs.

[0054] Embodiment 1:

[0057] The printing device also includes a control system for controlling the operation of the mimeograph system and the displacement adjustment system. The control system controls the operation of the mimeograph system and the displacement adjustment system, adjusts the position of the mimeograph system according to the position of the workpiece to be printed, and then transfers the words on the template device to the workpiece (product) through the pad printing head system. The accuracy of the pad printing position and the clarity of the handwriting are guaranteed, the work efficiency is improved, and the waste of raw materials is avoided.

[0058] As attached Figure 1 , 2As shown in FIG. 4 , the displacement adjustment system includes a lateral displacement adjustment device 3 for adjusting the lateral displacement of the mimeograph system and a longitudinal displacement adjustment device 2 for adjusting the longitudinal displacement of the mimeograph system; the longitudinal displacement adjustment device 2 is arranged on the frame 1, the lateral displacement adjustment device 3 is arranged on the longitudinal displacement adjustment device 2, and the mimeograph system is arranged on the lateral displacement adjustment device 3;

[0059] The longitudinal displacement adjustment device 2 includes a crossbeam 21, a crossbeam longitudinal guide rail 23, and a crossbeam driving device 24 connected to the crossbeam. The crossbeam 21 is arranged horizontally in the middle of the frame 1, and the crossbeam longitudinal guide rail 23 is arranged at both ends of the crossbeam 21. The crossbeam longitudinal guide rail 23 is fixed to both sides of the frame 21 through a crossbeam longitudinal guide rail fixing seat 28. The crossbeam sliding member 22 is arranged at both ends of the crossbeam 21. The crossbeam sliding member 22 is arranged corresponding to the crossbeam longitudinal guide rail 23. The crossbeam 21 moves up and down along the crossbeam longitudinal guide rail 23 relative to the vertical direction of the frame 1; the crossbeam sliding member 22 is fixed to the frame 1 through a crossbeam linear bearing seat 25; the longitudinal displacement adjustment device also includes a crossbeam counterweight shaft 26, which is arranged at the top of the frame 1, and the two ends of the crossbeam counterweight shaft 26 are connected to the two ends of the crossbeam 21 through a counterweight 27. The counterweight is a counterweight block or a counterweight tension spring. Since the total weight of the crossbeam 21, the trolley 31 on the crossbeam and the various structures arranged on the trolley 31 is relatively large, when the crossbeam 21 moves up and down relative to the frame 1, the entire printing device is prone to unbalance. After being equipped with a counterweight piece equivalent to the overall weight of the crossbeam 21, when the crossbeam 21 moves upward, the counterweight piece moves downward, thereby making the overall equipment run smoothly.

[0060] In order to improve the accuracy and clarity of printing, the hydraulic cylinder 241 is connected to a cylinder adjusting screw.

[0061] The asynchronous operation of the two ends of the beam 21 will not only affect the clarity and accuracy of the printing, but also easily cause overall failure of the equipment and increase the operating cost. Therefore, the beam drive device 24 includes a beam synchronization shaft 243, a beam synchronization gear 242, and a hydraulic cylinder 241. The end of the beam 21 is connected to the output end of the hydraulic cylinder 241, and the top of the hydraulic cylinder 241 is fixedly installed on the frame 1. The two ends of the beam synchronization shaft 243 are installed with beam synchronization gears 242, and the beam synchronization shaft 243 is connected to the beam 21. The beam synchronization shaft 243 cooperates with the beam synchronization gear 242 to achieve precise synchronization of the two ends of the beam 21, thereby avoiding equipment loss caused by asynchrony.

[0062] The lateral displacement adjustment device 3 includes a trolley 31, a trolley linear guide 32 and a trolley driving device 34 connected to the trolley. The trolley linear guide 32 is transversely fixed on the crossbeam 21. A trolley sliding member 33 is provided at the bottom of the trolley 31. The trolley sliding member 33 is provided corresponding to the trolley linear guide 32. The trolley 31 is displaced left and right along the trolley linear guide 32 relative to the horizontal direction of the frame 1. The trolley sliding member 33 here can be a slider, a sliding bearing, etc., in order to achieve the left and right displacement of the trolley along the trolley linear guide.

[0064] The template device includes a printing template 51, a template fixing frame 52 for fixing the printing template, a template guide rail 54, and a template driving device 56 connected to the template fixing frame 52. The template fixing frame 52 is horizontally arranged below the oil cup 41, and a template 51 is arranged below each oil cup 41. In actual use, the template 51 can be a steel plate, which is engraved with corresponding text or patterns according to actual needs, and the template 51 can be replaced at any time. The number of pad printing heads, oil cups and steel plates is set correspondingly and can be 2-10, which is set according to actual needs. It can be consistent with the number of each row of hand molds in the workpiece transmission system to be printed, or it can be half of the number of hand molds. For example, the number of hand molds in each row is 8, and the number of pad printing heads can be 4. Through the setting of the horizontal and vertical displacement adjustment devices, the flexibility of the displacement adjustment of the printing device is increased; each printing action only completes the printing of gloves on 4 hand molds, that is, the printing device completes the printing action of a row of 8 gloves in two printing action cycles.

[0065] A fixed side panel 53 is respectively provided at both ends of the template fixing frame 52, and the fixed side panel 53 is vertically welded to the upper surface of the trolley 31.

[0066] In actual operation, the template can be set to be stationary while the oil cup can slide relatively. As long as the two can be displaced back and forth to facilitate the pad printing head and the template, it can be done.

The material of the pad printing head is preferably silicone; the pad printing effect is clearer.

[0068] A pad guide rail 65 is fixed on the inner wall of the front end of the sliding plate 61, and pad slides 64 are provided at both ends of the pad fixing plate 62. The pad slides 64 are slidably arranged on the pad guide rail 65, so as to realize the vertical displacement of the pad 63, thereby completing the ink dipping and printing actions.

The number of the brackets is 2, and the two conveyor belts 72 surround the two brackets 71, and each conveyor belt 72 is circulated around the outer periphery of the same side wall of the two brackets 71. The vertical surface of the outer side of the conveyor belt where the workpiece to be printed runs from top to bottom is the first vertical surface I, and the printing device is correspondingly arranged at the first vertical surface, i.e., A; the vertical surface of the inner side of the conveyor belt where the workpiece to be printed runs from top to bottom is the second vertical surface II, which is the finished product unloading area, i.e., B; the vertical surface of the outer side of the conveyor belt where the workpiece to be printed runs from bottom to top is the third vertical surface III, which is the loading area for the workpiece to be printed, i.e., C. Among them, the crossbeam 21 is relatively inclined to the horizontal surface of the frame 1, the workpiece carrier 74 is relatively inclined to the horizontal surface of the bracket 71, and the inclination angle of the crossbeam 21 is the same as the inclination angle of the workpiece carrier 74 (workpiece support frame 73). In actual production, the inclination angle of the hand mold is different for different hand mold manufacturers, and setting the inclination angle of the crossbeam 21 to be consistent with the inclination angle of the hand mold is conducive to achieving parallel movement of the two, thereby making the printing action more accurate.
