[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding (including folding).

[0003] After searching, it is found that a paper bag printing machine is disclosed in Chinese patent documents [Application number: 202320584084.2; Publication number: CN 219236563 U]. This paper bag printing machine includes: a mounting bracket for installing various components. The utility model realizes a paper bag printing machine through the mutual cooperation of the mounting bracket, the protective shell, the conveying mechanism, the adsorption mechanism, the adjustment mechanism, the inkjet printer, the drying mechanism and the legs. Through the oblique setting of the adjusting roller mechanism, two equal thrusts to both sides are provided to the paper bag placed on the surface of the conveyor belt, and the offset paper bag is adjusted until it reaches the center position of the conveyor belt to complete the deviation correction process. At the same time, it has the effect of flattening the paper bag, ensuring the subsequent printing effect and improving the qualified rate of the product. The electric push rod pushes the connecting block to move so as to adjust the inclination angle of the adjusting roller mechanism so as to adapt to paper bags of different materials and thicknesses, expand the scope of use of the device, and improve the practicality of the device.

[0004] Although the adjustment mechanism disclosed in the patent can be adapted to paper bags of different materials and thicknesses, thus expanding the application range of the device and improving the practicality of the device, when the printed paper tape is reeled up, the limit block on the reeling roller cannot adjust the distance according to the different widths of the paper tape, and its use is limited.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A printing machine for processing multi-layer paper tapes comprises a mounting plate, which is rotatably connected to two rotating shafts, on which conveyor belt wheels are fixed, and the two conveyor belt wheels are connected by a conveyor belt, a discharging roller is rotatably connected to the right end of the mounting plate, a winding roller is rotatably connected to the left end of the mounting plate, two limit plates are slidably connected to the winding roller, a fixing mechanism is arranged between the winding roller and the limit plates, and a printing machine is fixed to the mounting plate.

[0008] The working principle of the utility model is as follows: the distance between the two limit disks of the winding roller is adjusted according to the width of the paper tape, and then it is fixed by a fixing mechanism, the paper tape that has not been printed on the discharge roller is sent to the bottom of the printing machine through a conveyor belt for printing, the printed paper tape is wound onto the winding roller, and the limit disk limits the paper tape on the winding roller, so that the distance between the limit disks can be adjusted according to the width of different paper tapes.

[0017] Compared with the prior art, the printing machine for multi-layer paper tape processing has the following advantages:

[0018] 1. Adjust the distance between the two limit disks on the winding roller according to the width of the paper tape, and then fix them through a fixing mechanism. The unprinted paper tape on the discharge roller is sent to the bottom of the printing press through a conveyor belt for printing. The printed paper tape is wound onto the winding roller, and the limit disk limits the paper tape on the winding roller, so that the distance between the limit disks can be adjusted according to the width of different paper tapes.

[0019] 2. By opening a fixing opening, a limiting opening and installing a latch, when the limit disk is adjusted to a good distance, the fixing opening on the fixing ring corresponds to the limiting opening on the winding roller and then the latch is inserted into it, thereby fixing the limit disk after the distance is adjusted to prevent displacement.

[0020] 3. Install the hollow block and the telescopic block. After the two limit plates have adjusted the distance, pull the telescopic block out of the hollow block to the same length according to the length of the distance. Place the telescopic block in the installation slot of the second fixed block. Block the outlet above the installation slot by rotating the stopper. Fix the telescopic block in the installation slot.
