[0023] See also Figure 1 - Figure 5As shown, a printing device for producing plastic packaging bags comprises a device body 1 and a conveying device 20; a guide mechanism is arranged on the device body 1, and the guide mechanism comprises a holder 21, the bottom end of the holder 21 is welded and fixed on the device body 1, a rotating rod 22 is rotatably connected inside the holder 21, the right side of the rotating rod 22 is fixed to the output shaft of a motor 24, the motor 24 is welded and fixed on the holder 21, the left and right sides of the rotating rod 22 are provided with threads with opposite rotation directions, two groups of moving blocks 23 are threadedly connected on the rotating rod 22, the bottom end of the moving block 23 is fixed to a connecting block 25 by welding, the connecting block 25 slides on a through slot 27, the through slot 27 is arranged at the bottom end of the holder 21, the bottom end of the connecting block 25 is fixed to a guide plate 26 by welding, and the bottom end of the guide plate 26 is close to the conveying device 20;

[0024] When working, a printing device for producing plastic packaging bags in the above-mentioned technology is not provided with a corresponding guide structure when the plastic packaging bags move on the conveyor. When the position of the plastic packaging bags placed on the conveyor is not aligned with the printing plate, the printing position of the pattern on the plastic packaging bags will change, affecting the printing quality. Through the structural design of the guide mechanism, the function of guiding the plastic packaging bags when they are conveyed on the conveying device 20 is realized. When the plastic packaging bags are conveyed on the conveying device 20, by placing the plastic packaging bags between the two sets of guide plates 26, the position of the plastic packaging bags can be adjusted by the two sets of guide plates 26. The guide plate 26 is provided to guide the conveying device 20 to avoid deviation during movement, thereby ensuring normal printing of subsequent patterns, and when the motor 24 rotates to drive the rotating rod 22 to rotate, the two groups of moving blocks 23 threadedly connected on the rotating rod 22 will move away from or approach each other, thereby achieving the purpose of adjusting the distance between the two groups of guide plates 26, so as to adapt to plastic packaging bags of different sizes and widths, wherein the bottom end of the guide plate 26 is close to the conveying device 20 but does not contact the conveying device 20, and the opening of the through groove 27 not only ensures the normal movement of the connecting block 25, but also limits the maximum moving distance of the moving block 23 to both sides on the rotating rod 22.

[0025] Furthermore, a cleaning mechanism is provided at the rear end of the guide plate 26, and the cleaning mechanism includes two sets of fixed shells 28, the fixed shells 28 are welded and fixed to the rear end of the guide plate 26, and the fixed shells 28 are rotatably connected to the first rotating rod 31 and the second rotating rod 32, and the first rotating rod 31 is welded and fixed with a moving wheel 30, and the bottom end of the moving wheel 30 is in contact with the conveying device 20, and the first rotating rod 31 and the second rotating rod 32 are both welded and fixed with two sets of clamping rings 33 on the side away from the moving wheel 30, and the first rotating rod 31 and the second rotating rod 32 are sleeved with a belt 34, and the side of the second rotating rod 32 away from the moving wheel 30 is fixed to the brush cylinder 35 by welding;

[0026] When working, the structural design of the cleaning mechanism can facilitate the cleaning of dust and debris on the surface of the plastic packaging bag, so as to ensure the cleanliness of the surface of the plastic packaging bag and avoid affecting the printing quality of the pattern during the printing process. Since the conveying device 20 is in contact with the moving wheel 30, the right conveying device 20 can drive the moving wheel 30 and make it rotate inside the fixed shell 28. The moving wheel 30 is fixed on the first rotating rod 31. When the first rotating rod 31 rotates, the rotation of the first rotating rod 31 is transmitted to the second rotating rod 32 through the belt 34 sleeved on the first rotating rod 31, and the second rotating rod 32 drives the brush cylinder 35 to rotate. At this time, the surface of the plastic packaging bag can be cleaned by the brush cylinder 35, wherein two sets of clamping rings 33 are fixed on the first rotating rod 31 and the second rotating rod 32. The clamping ring 33 is used to limit the position of the belt 34 to ensure that the belt 34 will not deviate on the first rotating rod 31 and the second rotating rod 32.

[0027] Furthermore, the middle portion of the rotating rod 22 is rotatably connected to the hanging ring 36, and the top end of the hanging ring 36 is welded and fixed inside the retaining frame 21;

[0028] During operation, the hanging ring 36 is designed to assist in supporting and fixing the rotating rod 22, so that the rotating rod 22 can be driven by the motor 24 to rotate more stably inside the retaining frame 21, and reduce the shaking of the rotating rod 22 during the rotation process.

[0029] Furthermore, the moving block 23 is penetrated by a guide rod 37, and both left and right sides of the guide rod 37 are welded and fixed inside the retaining frame 21, and the guide rod 37 penetrates the hanging ring 36;

[0030] During operation, the guide rod 37 is designed to guide the moving block 23 when it moves on the rotating rod 22, ensuring that the moving block 23 can move stably on the rotating rod 22. The guide rod 37 also passes through the hanging ring 36 to avoid contact with the hanging ring 36.

[0031] Furthermore, two groups of pads 38 are glued and fixed on the inner wall of the through groove 27, and the pads 38 are made of rubber material;

[0032] During operation, the cushion block 38 is made of rubber material and is used for buffering between the connecting block 25 and the inner wall of the through groove 27 .

[0033] Furthermore, the guide plate 26 is designed in a trapezoidal shape, and the bottom end of the guide plate 26 is hollowed out;

[0034] When working, the guide plate 26 is trapezoidal in design and the bottom end is hollowed out to reduce the weight of the guide plate 26 so that when the connecting block 25 drives the guide plate 26 to move, the moving block 23 will not be subjected to too much pulling force.

[0035] Working principle: In the prior art, a printing device for producing plastic packaging bags is not provided with a corresponding guide structure when the plastic packaging bags are moved on the conveyor. When the position of the plastic packaging bags placed on the conveyor is not aligned with the printing plate, the printing position of the pattern on the plastic packaging bags will change, affecting the printing quality. In this case, a printing device for producing plastic packaging bags realizes the function of guiding the plastic packaging bags when they are conveyed on the conveyor 20 through the structural design of the guide mechanism. When the plastic packaging bags are conveyed on the conveyor 20, the plastic packaging bags can be placed between the two sets of guide plates 26 to pass through the two sets of guide plates 26. To guide the position of the plastic packaging bag to avoid deviation during movement, thereby ensuring normal printing of subsequent patterns, and when the motor 24 rotates to drive the rotating rod 22 to rotate, the two groups of moving blocks 23 threadedly connected on the rotating rod 22 will move away from or approach each other, thereby achieving the purpose of adjusting the distance between the two groups of guide plates 26, so as to adapt to plastic packaging bags of different sizes and widths, wherein the bottom end of the guide plate 26 is close to the conveying device 20 but does not contact the conveying device 20, and the opening of the through groove 27 not only ensures the normal movement of the connecting block 25, but also limits the maximum moving distance of the moving block 23 to both sides on the rotating rod 22.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
