Description

Technical Field

[0001] The utility model relates to the technical field of airline ticket printers, in particular to a paper feeding roller assembly for an airline ticket printer. Background Art

[0002] The paper feed mechanism of a dot matrix printer is composed of main components such as the main drive shaft roller, paper feed motor, screw, paper guide, sensor (to detect the presence of paper), etc. The printing paper is pressed between the main drive shaft roller and the screw. The paper feed motor drives the print roller to rotate in the paper feed direction. Under the action of friction, the printing paper rotates along with the main drive shaft roller, thereby realizing the paper feeding action.

[0003] For traditional ticket printers, after the blank tickets on the paper feeding mechanism are used up, new blank tickets need to be reloaded. However, the existing paper feeding rollers are not easy to quickly install the empty ticket tubes on the paper feeding mechanism. In addition, during the paper feeding process, the current paper feeding mechanism may deviate during the transportation process, which may easily cause paper damage and affect the output of the ticket.

[0028] according to Figure 3-4 As shown, a card hole 8 is provided on both sides of the rotating shaft 4, and a fixing ring 9 is fixedly connected to the inner wall of the card hole 8, a spring 10 is fixedly connected to one side of the fixing ring 9, and a button 11 is fixedly connected to the other side of the spring 10. The button 11 includes three sections, namely an outer disk, an inner rod and a push rod. One side of the inner rod is fixedly connected to one side of the spring 10, and the outer disk is located on the outer side of the rotating shaft 4. One end of the push rod passes through the inner wall of the fixing ring 9 and extends to the other side of the fixing ring 9. A connecting column 12 is fixedly connected to one side of the adjusting plate 5, and a card rod 13 is movably connected to both sides of the connecting column 12. Sliding holes are provided on both sides of the connecting column 12, and a reset spring is arranged on the inner wall of the sliding hole. One end of the reset spring is fixedly connected to the card rod 13, and the outer wall of the card rod 13 is slidably connected to the inner wall of the sliding hole.

[0029] according to Figure 5-6 As shown, a slide rail 14 is provided on one side of the mounting frame 1, and the inner wall of the slide rail 14 is slidably connected to a limit assembly 15, and the limit assembly 15 includes a slider 151, one side of the slider 151 is fixedly connected to a connecting seat 152, the inner wall of the connecting seat 152 is fixedly connected to a connecting spring 153, both sides of the connecting seat 152 are provided with slide grooves 154, the other side of the connecting spring 153 is fixedly connected to a connecting plate 155, and the side wall of the connecting plate 155 is fixedly connected to a sliding block 156, the cross-sectional shape of the connecting seat 152 is a U-shaped opening shape, both sides of the connecting plate 155 are slidably connected to the inner wall of the slide groove 154 through the sliding block 156, one end of the connecting spring 153 is fixedly connected to the connecting plate 155, and the other side of the connecting plate 155 is fixedly connected to a limit plate 157.

[0030] When in use, by pressing the button 11, the button 11 drives the inner rod to move on the inner wall of the clamping hole 8 through the movement of the outer disk, and compresses the spring 10. At the same time, the push rod passes through the inner wall of the fixing ring 9 and extends to the other side of the fixing ring 9 to squeeze the clamping rod 13. At this time, the clamping rod 13 is pressed to squeeze the reset spring, and then the clamping rod 13 is away from the inner wall of the clamping hole 8. Therefore, the adjustment plate 5 can be pulled outward and taken out, and then a new paper roll can be placed on the outer wall of the paper feeding roller 3, so that the paper roll can be replaced. It is convenient and quick to use. The limit plate 157 is connected to the connecting plate 155, and The connecting plate 155 is slidably connected to the inner wall of the connecting seat 152 through the connecting spring 153, so the limiting plate 157 can move left and right, so as to push the paper on the surface of the paper tube and reduce the occurrence of paper deviation. Because the slider 151 is connected to one end of the inner wall of the slide rail 14 through the connecting spring, as the thickness of the paper on the surface of the paper tube increases, the limiting plate 157 drives the slider 151 to squeeze the connecting spring and move upward. This method ensures that the limiting plate 157 always covers the paper on the surface of the paper tube, avoiding the outermost paper of the paper tube from being too loose.

[0031] To sum up, the paper feed roller assembly for the airline ticket printer cooperates between structures such as the button 11 and the card rod 13. The card rod 13 uses the elasticity of the return spring to enable the adjustment plate 5 to be connected with the rotating shaft 4 through the card rod 13. By pressing the button 11, the card rod 13 can be squeezed to squeeze the return spring, thereby separating the adjustment plate 5 from the rotating shaft 4. Therefore, the paper tube on the outer wall of the paper feed roller 3 can be taken out and replaced with a new paper tube, which is convenient for the subsequent normal paper feeding of the airline ticket printer.

[0032] By setting the limit plate 157, the surface and side edges of the blank ticket can be abutted to prevent the blank ticket from deviating due to the large number and high stacking height during the paper feeding process. As the deviation angle increases, the blank ticket may be torn, affecting subsequent printing. The surface of the blank ticket can be squeezed to prevent the outermost layer of the blank ticket from being too loose, resulting in printing errors and other consequences.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
