[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during production and distribution. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to landfills for disposal like ordinary garbage, and only 7% of plastics are recycled. The surface of packaging bags is often printed using printing devices.

[0003] Application number CN202221018502.3 specifically describes a printing device for plastic packaging bags, which includes a base plate and other structures. This invention can not only stir the pigments required for printing to prevent them from solidifying, but also quickly dry the printed plastic packaging bags. However, in practical use, there is a problem: the printing operation will fail when encountering plastic packaging bags with wrinkled surfaces. Utility Model Content

Then, the bearing seat moves the rubber plate outward. The two rubber plates cooperate to flatten the packaging bag. Then, the cylinder is started, the printing machine descends, and prints on the packaging bag, resulting in a good printing effect.

[0008] In a preferred embodiment, this invention can be further configured as follows: two electric push rods are connected in series, and the electric push rods are electrically connected to an external power source.

[0009] In a preferred embodiment, the present invention can be further configured such that the cylinder, printing machine, electric push rod, and motor are all electrically connected to an external PLC.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of a plastic packaging bag printing device provided by this utility model.

[0027] Example 1:

[0028] Combination Figure 1-5 As shown, the present invention provides a plastic packaging bag printing device, including a printing mechanism 100, a pressing mechanism 200 and a flattening mechanism 300. The printing mechanism 100 includes an embossing table 110, a support plate 120 connected to the embossing table 110, a cylinder 130 passing through the top of the support plate 120, and a printing machine 140 connected to the movable end of the cylinder 130.

[0029] The pressing mechanism 200 includes an L-shaped pressure plate 210 that is movably attached to the top of the embossing table 110, and two electric push rods 220 connected between the embossing table 110 and the L-shaped pressure plate 210.

[0030] The leveling mechanism 300 includes two reciprocating screws 310 movably installed inside the L-shaped pressure plate 210, a bevel gear 320 sleeved on the outer end of the reciprocating screws 310, a motor 330 connected between one of the reciprocating screws 310 and the L-shaped pressure plate 210, a bearing seat 340 movably sleeved on the outside of the reciprocating screws 310, a rubber plate 350 connected to the bearing seat 340, and a plurality of memory metal rods 360 installed inside the rubber plate 350. The two bevel gears 320 mesh with each other.

[0031] Furthermore, the top of the L-shaped pressure plate 210 has two grooves suitable for the sliding of the bearing seat 340. The bearing seat 340 is T-shaped and the grooves provide conditions for the bearing seat 340 to slide.

[0032] Furthermore, the two rubber sheets 350 are attached to each other, with the bottom of the rubber sheet 350 attached to the top of the embossing table 110. The layout design of the two rubber sheets 350 ensures that the two rubber sheets 350 can flatten the packaging bag from two directions.

[0033] Furthermore, the multiple memory metal rods 360 inside the rubber sheet 350 are equally spaced and arranged in a row. This structural design allows the two rubber sheets 350 to fit tightly together, ensuring that the packaging bag can be flattened when they work together.

[0035] Combination Figure 1 and Figure 3 As shown, based on Embodiment 1, two electric push rods 220 are connected in series. The electric push rods 220 are electrically connected to an external power supply. The connection method of the two electric push rods 220 is completed by the electrician during assembly. This connection method facilitates the use of this device.

[0036] Example 3:

[0037] Combination Figure 1-5 As shown, in the above embodiment, the cylinder 130, printing machine 140, electric push rod 220, and motor 330 are all electrically connected to an external PLC. The control method of this utility model is to achieve automatic control through an external PLC. The control circuit of the external PLC can be implemented by those skilled in the art through simple programming.

[0038] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the packaging bag is placed on the top of the embossing table 110. Then, the external PLC controls the two electric push rods 220 to retract their movable ends. Then, the L-shaped pressure plate 210 presses the edge of the packaging bag. Then, the motor 330 is started. Then, the two bevel gears 320 mesh, and the two reciprocating screws 310 rotate simultaneously. Then, the bearing seat 340 moves the rubber plate 350 outward. The two rubber plates 350 cooperate to flatten the packaging bag. Then, the cylinder 130 is started, the printing machine 140 descends, and prints on the packaging bag. The printing effect is good.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
