DETAILED DESCRIPTION
[0025] The present invention is further described below through specific implementation methods. The following description is only for exemplary explanation. Those skilled in the art can make further structural improvements based on the following explanation. The scope of protection of this patent shall be based on the scope recorded in the claims.
[0026] Embodiment 1:
[0027] A mobile modular printing machine, as shown in the attached drawings, comprises a longitudinal track 1, on which a machine table 2 is arranged, and at the bottom of which a longitudinal wheel 25 is arranged, and the machine table 2 moves longitudinally by cooperating with the longitudinal track 1 through the longitudinal wheel 25.
[0028] The machine 2 is provided with a negative pressure bin 22 and a negative pressure synchronous suction fan 3, and the negative pressure bin 22 is provided with a lift 21, and the driving end of the lift 21 is connected to an external lift drive motor 24. The negative pressure bin 22 can be driven by the lift drive motor 24 to move up and down and squeeze the printing unit 6. The top surface of the negative pressure bin 22 is provided with a plurality of negative pressure holes and pulleys, and negative pressure suction is achieved through the negative pressure holes, and the pulleys can promote the smooth movement of the straight plate.
[0029] A top frame 5 is provided on the top of the machine 2, and a top transverse track 52 is provided on the top frame 5; a transverse track 11 is provided on the side of the machine 2, and the transverse track 11 and the top transverse track 52 jointly support a plurality of printing units 6; a pulley block 62 is provided at the bottom end of the right side plate 61 of the printing unit 6 to cooperate with the transverse track 11, and an extension support portion 53 is provided on the top of the left side plate 69 of the printing unit 6, and the extension frame 54 is fixed by the extension support portion 53, as shown in FIG. Figure 2 As shown, the extension frame 54 is a T-shaped structure, with sliders 55 on both sides. In conjunction with the sliders 55 on the left and right sides, each printing unit 6 is provided with two top transverse rails 52. This structure can improve the stability of the printing unit 6 during transverse movement.
[0030] When the device is in operation, a positioning device or a locking device is provided at the bottom of the right side plate 61 of the printing unit 6, and the locking of the printing unit 6 in a fixed state is realized by the positioning device or the locking device. A person skilled in the art can select a vertically arranged positioning cylinder 63, set a positioning hole on the transverse track 11, and realize positioning by driving the positioning rod to be plugged into the positioning hole on the transverse track 11 through the positioning cylinder 63. When the printing unit 6 is in normal operation, the positioning cylinder 63 is used for positioning, so that the printing unit 6 can be prevented from moving disorderly in the printing state.
[0031] Furthermore, a support wheel 70 is provided at the bottom of the left side plate of the printing unit 6, and a positioning track 23 is provided on the machine 1. The positioning track 23 cooperates with the support wheel 70 to realize the support and fixation of the printing unit 6 after positioning when working inside the machine 1. This design can avoid the left end of the printing unit 6 from hanging and prevent it from falling during normal use.
[0032] Furthermore, a transverse drive device is provided between the printing unit 6 and the machine 1, and the transverse drive between the printing unit 6 and the machine 1 is realized by the transverse drive device. In this embodiment, the transverse drive is realized by providing a transverse drive motor driving gear on the machine 1, and a toothed belt is provided on the printing unit 6 to mesh with the gear. When changing the printing plate, replacing the anilox roller, rubber roller, scraper, and overhauling the color group, the transverse drive motor can be used to drive the toothed belt to realize the transverse disengagement of the two. With the same design principle, those skilled in the art can also provide a transverse drive cylinder between the printing unit 6 and the machine 1, and realize the transverse disengagement between the two by the transverse drive cylinder. After disengagement, the operator can change the printing plate, replace the anilox roller, rubber roller, scraper, and overhaul the color group externally, and the operation space is large and the operation is more convenient.
[0033] When the negative pressure bin 22 is sucked by the synchronous suction fan 3, the debris and paper scraps generated during the suction process pass through the synchronous suction fan 3 and enter the negative pressure treatment bin 4 for secondary treatment. Figure 1 , 2 As shown in 3, a negative pressure treatment chamber 4 is arranged above the machine 1 and is connected to the synchronous suction fan 3. A filtering device is arranged inside the negative pressure treatment chamber 4 to uniformly process the carton debris sucked from the negative pressure chamber 22.
[0034] Embodiment 2:
[0035] On the basis of Example 1, when the printing plate is replaced by the present technical solution, the original equipment mostly adopts manual replacement. Because the degree of automation of the equipment is getting higher and higher, this manual replacement method is gradually replaced by automation. However, during automatic operation, when the printing plate is replaced by automation, the driving mechanism will pull the printing plate to rotate on the printing roller. When the rotation amplitude exceeds the rotation amplitude of the roller shaft, there is a risk of damaging the printing plate. To prevent this problem from occurring, the present invention is provided with a printing roller 66, an anilox roller 67 and a glue ink roller 68 inside the printing unit 6. A printing roller drive motor 64 is provided at the end of the printing roller 66 to provide power for it, and an anilox roller drive motor 60 is provided at the end of the glue ink roller 68 to provide power for it. A synchronous drive group 65 is provided at the other end of the anilox roller 67 and the glue ink roller 68, and the synchronous linkage of the anilox roller 67 and the glue ink roller 68 is achieved through the synchronous drive group 65.
[0036] like Figure 6As shown, the printing roller 66 is provided with an automatic plate locking mechanism 7, which includes an electromagnetic brake 71, and a brake gear 72 is provided on the electromagnetic brake 71 to mesh with the outer gear 73 on the roller shaft; the roller shaft is also provided with an inner gear 74 to mesh with the transition planetary gear 75, and the transition planetary gear 75 is meshed with the roller shaft gear 76, and the roller shaft gear 76 is fixed to the roller shaft. Further, a limiter 77 is provided on the transition planetary gear 75, and the limiter 77 is used to limit the disorderly rotation of the roller. The working principle is that when the external pulling machine drives the printing plate to rotate, when the pulling resistance is large, the limiter 77 is triggered, and the roller shaft gear 76 drives the printing plate to use the transition planetary gear 75 as the transition wheel, which rotates around the outer gear 73 and the inner gear 74. In this way, the printing plate is prevented from being damaged when the external pulling force is too large.
[0037] In summary, the mobile modular printing press breaks the characteristics of traditional printing presses. Without stopping the machine, the printing unit is moved out and in to replace the printing plate, replace the anilox roller, rubber roller, and scraper, and to overhaul the color group. The present invention is equipped with a synchronous suction fan to make the cardboard conveying more accurate, stable, and efficient, saving 20% to 30% of energy consumption, and is equipped with a dust collection system. Each axis is independently driven by a servo, making printing more accurate and overprinting more precise.
