Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a paper dispensing device for printing. Background Art

[0002] The printing press transfers the printed plate with patterns, text and other information onto paper or other media through a series of processes such as paper cutting, oiling and embossing, forming a finished product with functions such as information transmission and decoration. Different types of printing presses, such as letterpress printing presses, gravure printing presses, lithography printing presses and digital printing presses, have different printing methods, and when the printing press is in use, there is usually a paper loading device on one side.

[0003] When using a rolled paper roll, the traditional paper dispensing device pulls the paper roll to rotate through the machine operation, so that the paper is rolled out for printing. However, when the printing press stops, the paper roll will continue to rotate due to inertia, causing the paper to be excessively rolled out, causing the paper to drag on the ground and cause waste.

The outer wall of the support rod 14 fits with one side of the two friction plates 501, and the two ends of the spring 504 are respectively connected to one side of the sliding sleeve seat 502 and one side of the built-in groove 506, and the embedding box 505 is embedded in the bottom of the placement groove 11, the outer wall of the sliding sleeve seat 502 is slidably connected with the inner wall of the built-in groove 506, and the two sides of the toggle rod 508 are slidably connected with the inner wall of the toggle groove 507, and a rotating groove 10 is provided on one side of the placement groove 11, and the inner wall of the rotating groove 10 is rotatably connected with the outer wall of the support rod 14.

[0028] The utility model can, by setting the friction device 5, use the elastic force of the spring 504 to make the spring 504 drive the two sliding seats 502 to move toward each other, and then make the two sliding seats 502 drive the top friction plates 501 to approach each other, so that the two friction plates 501 contact and squeeze the outer wall of the support rod 14, and then generate a certain resistance to the support rod 14, so as to avoid the waste caused by the paper continuing to roll out due to inertia when the machine stops, and by setting the short sliding rod 503, the spring 504 is prevented from bending when being subjected to force, which affects the elastic force of the spring 504.

[0029] A second movable groove 8 is provided on one side of the top of the bottom plate 2, a bearing is embedded on one side of the second movable groove 8, and a rotating shaft is rotatably connected in the bearing, and a double-grooved rod 9 is connected to one end of the rotating shaft, a motor 6 is fixedly installed on one side of the bottom plate 2, the output shaft of the motor 6 extends into the second movable groove 8 and is connected to one end of the double-grooved rod 9, the outer wall of the double-grooved rod 9 is threadedly connected to a threaded seat 12, the top of the threaded seat 12 is connected to the bottom of the vertical plate 1, and two sliders 13 are connected to the bottom of the vertical plate 1, two slide grooves 7 are provided on one side of the top of the bottom plate 2 close to the second movable groove 8, and the inner wall of the slide groove 7 is slidably connected to the outer wall of the slider 13, and the top of the bottom plate 2 is away from the second movable groove 8. A first moving groove 3 is opened on one side of the second moving groove 8, and a correcting device 4 is arranged in the first moving groove 3. The correcting device 4 includes two moving blocks 403. A sliding sleeve is embedded in the moving block 403, and a long sliding rod 404 is slidably connected in the sliding sleeve. Two ends of the long sliding rod 404 are respectively connected to two sides of the inner wall of the first moving groove 3, and the outer wall of the moving block 403 is slidably connected to the inner wall of the first moving groove 3. A correcting plate 401 is connected to the top of the moving block 403, and nuts are embedded in the tops of the two moving blocks 403, and bolts 402 are connected to the inner threads of the nuts, and one end of the bolt 402 is in contact with the outer wall of the long sliding rod 404.

[0030] The utility model can, by setting a deviation correction device 4, screw the bolt 402 so that one end of the bolt 402 is separated from the outer wall of the long sliding rod 404, and then move the moving block 403 left and right, so that the moving block 403 drives the top deviation correction plate 401 to move, thereby making the distance between the two deviation correction plates 401 adjustable.

[0031] Working principle: The double-threaded rod 9 is driven to rotate by the rotation of the motor 6. Two opposite threads are arranged on the outer wall of the double-threaded rod 9, so that the two threaded seats 12 drive the top vertical plate 1 to move to both sides, and then the paper roll is put in. The motor 6 is reversed to make the threaded seat 12 drive the vertical plate 1 to move in the opposite direction, and make the two ends of the support rod 14 pass through the rotating groove 10, and then start printing. By moving the moving block 403, the moving block 403 drives the top correcting plate 401 to move, so that the two correcting plates 401 guide and correct the paper to prevent the offset paper from affecting the subsequent printing. When the machine stops, the elastic force of the spring 504 makes the two sliding sleeve seats 502 drive the friction plate 501 to squeeze the support rod 14, thereby generating resistance to the rotation of the support rod 14, thereby preventing the paper roll from being wasted due to inertia mechanical rolling out when the machine stops.
