[0004] To address the problem of existing structures being unable to dry printed packaging bags, current technologies employ a combination of components such as drying chambers. However, this approach still fails to prevent ink sedimentation. The ink remains essentially stagnant within the ink tank of the existing structure, and after a period of operation, ink sedimentation easily occurs, resulting in poor printing quality on the packaging bags. Utility Model Content

[0005] The purpose of this invention is to provide a surface printing device for packaging bag production, which solves the problem in the prior art that ink tends to settle after a period of time, resulting in a deterioration in printing effect.

[0007] The anti-settling mechanism includes an extension seat, which is fixedly installed on the left side of the support frame. An elastic element is fixedly installed on the top of the extension seat, and a positioning plate is fixedly installed on the top of the elastic element. An extension base is fixedly installed on the front of the extension seat, and a motor is fixedly installed on the top of the extension base. A cam is fixedly connected to the output shaft of the motor. A roller is rotatably connected to the front of the positioning plate, and the outer surface of the cam is movably connected to the outer surface of the roller.

[0008] As a preferred embodiment of the above technical solution, the top of the positioning plate is provided with an embedding groove, an ink cartridge is movably inserted into the inner cavity of the embedding groove, and a locking bolt is threaded onto the outer wall of the positioning plate, the end of the locking bolt being movably connected to the outer wall of the ink cartridge.

[0009] As a preferred embodiment of the above technical solution, a sealing cap is movably inserted into the top of the ink cartridge, and a venting bend is fixedly connected to the top of the sealing cap.

[0010] As a preferred embodiment of the above technical solution, a valve is fixedly connected to the bottom of the ink cartridge, and a suction hose is fixedly connected to the bottom of the valve. The end of the suction hose away from the valve is fixedly connected to the ink input end of the printing equipment body.

[0011] As a preferred embodiment of the above technical solution, the progressive drying assembly includes a support plate, which is fixedly installed on the top of the working frame. From left to right, square tubes No. 1, No. 2, No. 3, and No. 4 are fixedly installed on the front of the support plate.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1-3 As shown, this utility model provides a technical solution: a surface printing device for packaging bag production, including a working frame 1, a conveyor belt 2 disposed on the inner wall of the working frame 1, a support frame 11 welded to the outer wall of the working frame 1, a printing device body 12 fixedly installed on the top of the support frame 11, an anti-settling mechanism 3 disposed on the left side of the support frame 11, and a progressive drying assembly disposed on the top of the working frame 1. The anti-settling mechanism 3 includes an extension seat 31, which is fixedly installed on the left side of the support frame 11. An elastic element 32 is fixedly installed on the top of the extension seat 31, and a positioning plate 33 is fixedly installed on the top of the elastic element 32. An extension seat 34 is fixedly installed on the front of the device, and a motor is fixedly installed on the top of the extension seat 34. A cam 35 is fixedly connected to the output shaft of the motor. A roller 36 is rotatably connected to the front of the positioning plate 33. The outer surface of the cam 35 is movably connected to the outer surface of the roller 36. The operation of the motor is controlled to drive the cam 35 to rotate. The rotating cam 35 can continuously impact the roller 36, causing the ink in the inner cavity of the ink cartridge 39 to vibrate, thus avoiding the problem of ink sedimentation. The packaging bag can be transported by the operation of the conveyor belt 2. The operation of the main body 12 of the printing equipment can be controlled to extract the ink inside the ink cartridge 39 for printing.

[0023] As one implementation method in this embodiment, such as Figures 1-3 As shown, the top of the positioning plate 33 has an embedded groove 37, and an ink cartridge 39 is movably inserted into the inner cavity of the embedded groove 37. A locking bolt 38 is threaded onto the outer wall of the positioning plate 33, and the end of the locking bolt 38 is movably connected to the outer wall of the ink cartridge 39. A sealing cover 391 is movably inserted into the top of the ink cartridge 39, and a venting bend 392 is fixedly connected to the top of the sealing cover 391. A valve 393 is fixedly connected to the bottom of the ink cartridge 39, and a suction hose 394 is fixedly connected to the bottom of the valve 393. The suction hose 394 is located away from the valve 393. One end of 93 is fixedly connected to the ink input end of the main body 12 of the printing equipment. The sealing cover 391 is pulled out from the top of the ink box 39, and ink can be added to the inner cavity of the ink box 39. The design of the ventilation bend 392 allows the ink box 39 to be ventilated to the outside, which facilitates the extraction work and also makes it easy for the user to move the sealing cover 391. The actual length of the extraction hose 394 is designed according to the usage environment. When the main body 12 of the printing equipment is working, the ink inside the ink box 39 can be extracted by extracting the hose 394.

[0024] As one implementation method in this embodiment, such as Figure 1 , Figure 4 As shown, the progressive drying assembly includes a support plate 14, which is fixedly installed on the top of the working frame 1. From left to right, square tubes 16, 17, 18, and 19 are fixedly installed on the front of the support plate 14. Air jet pipes 191 are fixedly connected to the sides of square tubes 16, 17, 18, and 19. A hollow plate 13 is fixedly connected to the front of square tubes 16, 17, 18, and 19, and is fixedly installed on the top of the working frame 1. A hot air blower 15 is fixedly installed on the front of the hollow plate 13, and the output end of the hot air blower 15 is connected to the hollow plate 19. The front of the 3 is fixedly connected to control the operation of the hot air blower 15, which can absorb and heat the outside air, and then deliver it into the hollow plate 13. The air then passes through the first square tube 16, the second square tube 17, the third square tube 18 and the fourth square tube 19 and is ejected from the jet pipe 191 to complete the drying process of the printed packaging bag, thereby improving the printing quality. The first square tube 16, the second square tube 17 and the third square tube 18 are all designed with an inclined angle, which is set to 30 degrees, 45 degrees and 60 degrees respectively. This allows hot air to be delivered to the left, realizing the function of gradually drying the printed packaging bag, avoiding the problem of insufficient drying caused by directly delivering hot air from the vertical direction.

[0025] Working principle: Controlling the operation of conveyor belt 2 can transport packaging bags; controlling the operation of printing equipment body 12 can extract ink from ink box 39 for printing; controlling the operation of motor can drive cam 35 to rotate, and the rotating cam 35 can continuously impact roller 36, causing the ink in the inner cavity of ink box 39 to vibrate, achieving the function of preventing sedimentation; controlling the operation of hot air blower 15 can output hot air from air jet pipe 191 to achieve the function of drying the printed packaging bags.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
