[0014] 1. The utility model conveys the plastic bags to be printed to the bottom of the printing machine through the conveyor table, and automatically completes the surface printing process. When the plastic bag is printed, the third cylinder drives the suction plate to descend, and cooperates with the negative pressure provided by the air pump to firmly absorb the plastic bag. This process greatly improves production efficiency, reduces manual operations, and ensures product consistency and quality.

[0015] 2. The utility model is started by the second cylinder, and the piston rod pushes the sliding plate to move horizontally along the limit frame, and the plastic bag adsorbed on the suction plate is accurately moved to the collection table.

[0023] See also Figure 1-5 , an embodiment provided by the utility model:

[0024] A surface printing machine for plastic bag production, comprising a conveyor 1, a printing machine 2 is installed on the top of the conveyor 1, and one end of the conveyor 1 is a discharging end, and the other end of the conveyor 1 is a feeding end, a limit frame 9 is fixedly installed on the top of the discharging end of the conveyor 1, and both ends of the limit frame 9 are fixedly installed with a cross bar 911, both sides of the limit frame 9 are provided with a slide groove, and a sliding plate 914 is movably installed in the slide groove, and a plurality of groups of connecting rods 917 are fixedly installed on the top of the plurality of groups of connecting rods 917, and a top plate 915 is fixedly installed on the outer surface of the top plate 915 The third cylinder 916 is connected to an air suction plate 918 at its end, and a plurality of air suction holes are provided on the outer surface of the air suction plate 918. A rubber tube 812 is connected to one side of the air suction plate 918, and an air pump 811 is connected to one end of the rubber tube 812, and the air pump 811 is fixedly mounted on the outer surface of the top end of the connecting rod 917. The second cylinder 912 is fixedly mounted on the outer surfaces of both sides of one side of the limiting frame 9, and a piston rod 111 is connected to one end of the second cylinder 912, and a sliding plate 914 is connected to one end of the piston rod 111. A collecting platform 711 is connected to one side of the conveying platform 1.

[0025] Furthermore, an air valve 813 is provided on the outer surface of one end of the rubber tube 812, and the provision of the air valve 813 allows the operator to more accurately control the air flow between the air pump 811 and the air suction plate 918. When necessary, the air valve 813 can be quickly closed to stop the air suction or opened to start the air suction, thereby improving the flexibility and accuracy of the operation.

[0026] Furthermore, a second fixing plate 919 is fixedly installed at the bottom end of the second cylinder 912, and one side of the second fixing plate 919 is fixedly installed to one side of the bottom end of the limiting frame 9, and multiple groups of reinforcement rods 913 are fixedly installed between the second cylinders 912. The design of the second fixing plate 919 enhances the stability between the second cylinder 912 and the limiting frame 9, and helps to ensure the smoothness and accuracy of the sliding plate 914 during the movement, thereby improving the reliability and durability of the entire system. The multiple groups of reinforcement rods 913 increase the stability between the second cylinders 912.

[0027] Furthermore, mounting plates 3 are fixedly mounted on both sides of the top of the feed end of the conveyor platform 1, and multiple groups of first cylinders 4 are fixedly mounted on the outer surface of the mounting plates 3, and one end of the multiple groups of first cylinders 4 is connected to an adjustment plate 5. Through the combination of the first cylinders 4 and the adjustment plate 5, the width of the feed end of the conveyor platform 1 can be adjusted as needed to accommodate plastic bags of different sizes. This flexibility improves the versatility and adaptability of the equipment.

[0028] Furthermore, a first fixing plate 8 is fixedly mounted on the bottom end of the plurality of first cylinders 4, and one side of the first fixing plate 8 is fixedly connected to the outer side of the conveying platform 1. The first fixing plate 8 ensures the stable installation of the first cylinder 4 and prevents it from shaking or shifting during operation. This helps to maintain the precise position of the adjustment plate 5, thereby ensuring that the plastic bag can be accurately placed on the conveying platform 1.

[0029] Furthermore, support rods 6 are fixedly installed on both sides of the top of the feeding end of the conveyor table 1, and a laser scanner 7 is fixedly installed on the top of the support rods 6. The laser scanner 7 can automatically detect the size, position and shape of the plastic bag and provide accurate adjustment data for the printer 2. This automatic detection function improves the accuracy and efficiency of printing and reduces the errors and costs of manual operation.

[0030] Furthermore, the outer surface of the adjustment plate 5 is wrapped with rubber. Rubber is a soft material. Wrapping the outer surface of the adjustment plate 5 can reduce scratches and damages to the surface of the plastic bag.

[0031] Working principle: First, the plastic bag to be printed is placed on the feeding end of the conveyor table 1. As the conveyor table 1 continues to operate, the plastic bag is conveyed to the bottom of the printing machine 2 and is processed by the printing machine 2 for surface printing.

[0032] Once the plastic bag is printed and reaches the discharge end through the conveyor 1, the third air cylinder 916 starts to work, driving the suction plate 918 to descend to a position close to the surface of the plastic bag. Then, the air pump 811 starts to provide negative pressure to the inside of the suction plate 918 through the rubber tube 812, so that the bottom surface of the suction plate 918 generates a strong suction force, thereby firmly adsorbing the printed plastic bag.

[0033] Subsequently, the second cylinder 912 is started, and the sliding plate 914 connected thereto is pushed by the piston rod 111 to move horizontally along the slide groove of the limiting frame 9. This action causes the plastic bags adsorbed on the suction plate 918 to be driven together and move from the discharge end of the conveying table 1 to above the adjacent collecting table 711.

[0034] When the sliding plate 914 and the adsorbed plastic bag reach the predetermined position of the collecting table 711, the air pump 811 stops working, releasing the negative pressure inside the suction plate 918, thereby canceling the adsorption of the plastic bag. At this time, the plastic bag naturally falls due to the effect of gravity and is stably placed on the top surface of the collecting table 711, completing the entire printing and collecting process.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
