[0035] An embodiment of the present application discloses an automatic printing machine for packaging.

[0036] Referring to Figure 1 , an automatic printing machine for packaging includes a frame 1, on which a feeding mechanism 2, a printing device 3, a dryer 4, a conveyor belt 5, and a receiving mechanism 6 are provided. Moreover, the feeding mechanism 2, the printing device 3, the dryer 4, the conveyor belt 5, and the receiving mechanism 6 can all be routinely disassembled on the frame 1, which is convenient for equipment maintenance and upgrade, and improves flexibility and scalability.

[0037] The conveyor belt 5 is rotatably arranged on the frame 1. The feeding mechanism 2 is arranged at the feeding end of the conveyor belt 5, and the material receiving mechanism 6 is arranged at the discharging end of the conveyor belt 5. The printing device 3 and the dryer 4 are respectively arranged along the conveying direction of the conveyor belt 5 and are located directly above the conveyor belt 5.

[0038] The packaging material is conveyed to the conveyor belt 5 through the feeding mechanism 2. The conveyor belt 5 conveys the packaging material to pass through the printing device 3 for printing and through the dryer 4 for drying. Finally, the packaging material is collected by the material receiving mechanism 6, and the whole process is mechanized.

[0039] During use, after the packaging material is fed from the feeding mechanism 2 and placed on the conveyor belt 5, the conveyor belt 5 conveys the packaging material into the printing device 3 for printing. Then, the printed packaging material is conveyed by the conveyor belt 5 into the dryer 4 for drying the dye. Then, it is discharged from the discharging end of the conveyor belt 5 to the material receiving mechanism 6 for collecting the packaging material. By arranging the feeding mechanism 2, the printing device 3, the dryer 4, the conveyor belt 5 and the material receiving mechanism 6 on the frame 1, integrating multiple links such as feeding, printing, drying and discharging into one, the overall production efficiency and automation level are improved. At the same time, the intervention of manual labor in the middle is reduced, the loading and unloading process of articles is optimized, the production quality is improved, and the labor cost is saved.

[0040] In this embodiment, the printing device 3 uses an existing multi-color rotary printing machine to print the packaging material. At the same time, the rotary printing device uses an environmentally friendly ink jet printing method and environmentally friendly ink to reduce pollution and ensure food safety and environmental protection. The dryer 4 uses an industrial dryer to dry the dye printed on the surface of the packaging material. The industrial dryer may adopt various drying technologies such as hot air circulation, far-infrared radiation, and microwave to improve the drying efficiency and quality. The conveyor belt 5 uses a flat conveyor belt made of heat-resistant material.

[0041] Refer to Figures 1-3 As shown in the figure, the feeding mechanism 2 includes a feeding lifting table 21 and a feeding component 22. The feeding lifting table 21 is located at the bottom of the frame 1, and the feeding component 22 is arranged between the feeding lifting table 21 and the conveyor belt 5. The feeding mechanism 22 includes a feeding lifting table 21 and a feeding component 22. The feeding lifting table 21 is located at the bottom of the frame 11, and the feeding component 22 is located at the top of the frame 11 and is close to the feeding end of the conveyor belt 5.

[0042] More specifically, the feeding component 22 includes a mounting frame 221, a plurality of lifting cylinders 222, a plurality of suction cups 223, a plurality of rolling wheels 224 and a conveying table 225.

[0043] The mounting frame 221 is fixed to the frame 1, and the conveying platform 225 is arranged on the feeding lifting platform 21 and the conveying platform 225 is close to one end of the conveyor belt 5, and the conveying platform 225 is arranged opposite to the mounting frame 221;

[0044] A plurality of lifting cylinders 222 are fixedly arranged on the mounting frame 221, and a suction cup 223 is fixedly arranged at the output end of the lifting cylinder 222;

[0045] A plurality of rolling wheels 224 are rotatably disposed between the mounting frame 221 and the conveying platform 225, and the plurality of rolling wheels 224 and the plurality of suction cups 223 are spaced apart from each other;

[0046] When in use, the packaging material is placed on the feeding lifting platform 21, and the lifting cylinder 222 drives the suction cup 223 to descend, so that the suction cup 223 absorbs the packaging material, and then drives the lifting cylinder 222 to drive the suction cup 223 to move upward until the packaging material contacts the rolling wheel 224, and the lifting cylinder 222 stops moving, and the rolling wheel 224 on the mounting frame rotates. After the rolling wheel 224 contacts the packaging material, the packaging material is brought to the rolling wheel 225 on the conveying platform 225, and at the same time transported to the conveyor belt 5 for transportation. At the same time, when the packaging material is continuously loaded, the feeding lifting platform 21 continuously rises, which effectively optimizes the loading of items, reduces manual intervention, improves production quality, and saves labor costs.

[0047] Reference Figures 2-3 A receiving plate 211 for contacting with the packaging material is provided on the feeding lifting platform 21, and a yielding portion 212 for avoiding the forklift is provided at the receiving end of the receiving plate 211, which effectively facilitates the placement of the fork arm of the forklift during the forklift loading process of the packaging material and reduces the wear of the fork arm on the feeding lifting platform 21.

[0048] Reference Figures 3-4 The receiving mechanism 6 includes two sets of correction components 61 and a receiving lifting platform 62. The two sets of correction components 61 are respectively arranged on the side walls of the frame 1, and the correction components 61 are located above the receiving lifting platform 62. The receiving lifting platform 62 is arranged at one end of the frame 1 and is adjacent to the discharge end of the conveyor belt 5.

[0049] More specifically, the correction component 61 includes a hydraulic cylinder 611 and a correction plate 612, the hydraulic cylinder 611 is fixedly arranged on the outer wall of the frame 1, and the hydraulic cylinder 611 drives the correction plate 612 to move above the receiving lifting platform 62. The correction component 61 includes a hydraulic cylinder 611 and a correction plate 612, the hydraulic cylinder 611 is fixedly arranged on the outer wall of the frame 11, and the hydraulic cylinder 611 drives the correction plate 612 to move;

[0050] More specifically, a channel area 613 for the packaging material to fall is formed between the two correction plates 612. The upper ends of the correction plates 612 are inclined downward toward the channel area 613 for guiding the packaging material to fall onto the receiving lifting table 62. The upper ends of the correction plates 612 are inclined, effectively reducing the wear between the correction plates 612 and the packaging material.

[0051] During use, the printed and dried packaging material is conveyed to the receiving mechanism 6 through the conveyor belt 5, and is guided by the correction assembly 61 to be neatly stacked on the receiving lifting table 62. At the same time, as the packaging material is continuously stacked, the receiving lifting table 62 continuously moves downward, effectively storing the packaging material completely on the receiving lifting table 62, preventing the stored packaging material from colliding with the just-transported packaging material. At the same time, the setting of the receiving mechanism 6 effectively optimizes the unloading process of the article, reduces manual intervention, improves the production quality, and saves labor costs.

[0052] In the above feeding mechanism 2 and receiving mechanism 6 embodiments, the feeding lifting table 21 and the receiving lifting table 62 both adopt electric lifting tables. The rolling wheels 224 are made of a static-eliminating rubber material on the surface, and the rolling wheels 224 adopt an electric rolling wheel 224.

[0053] Refer to Figures 3-4 , a material blocking assembly 7 is further provided at the discharging end of the frame 1. The material blocking assembly 7 includes two automatic side-pushing doors and a track 72. The two automatic side-pushing doors are mirror-symmetrically slidably arranged at both ends of the track 72. The track 72 is fixedly arranged at the bottom of the frame 1. A material blocking assembly 77 is further provided at the discharging end of the frame 11 of the frame 1. The material blocking assembly 77 includes an automatic side-pushing door 71 and a track 72. The automatic side-pushing door is slidably arranged on the track 72. The track 72 is fixedly arranged at the bottom of the frame 11.

[0054] During use, by setting the two automatic side-pushing doors 71 to move and open from the middle of the guide rail 72 to both sides, it can effectively prevent the finished product from being conveyed outside the frame 1 as the conveying part rotates, enabling the finished product to gather on the receiving lifting table 62, facilitating the collection of the finished product. At the same time, the middle opening setting optimizes the loading and unloading processes of the article, improves the production efficiency, and reduces manual intervention.

[0055] Refer to Figure 1 , heat dissipation ports 8 are provided on the outer walls of the printing device 3 and the dryer 4, which helps to dissipate heat and cool the printing device 3 and the dryer 4 through air intake.

[0056] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
