Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, and in particular to a paper punch for printing. Background Technology

[0002] Paper is one of the four essential elements of printing. It can be divided into letterpress printing paper, newsprint, offset printing paper, coated paper, book cover paper, dictionary paper, tracing paper, and cardboard, etc. Sometimes, it is necessary to punch holes in the paper when storing it.

[0003] Existing paper punching equipment typically has a fixed distance between the two holes. When the distance between the two holes changes, the equipment needs to be replaced, resulting in low equipment flexibility and increased production costs.

[0004] Therefore, we developed a paper punch for printing that can change the punch spacing. Utility Model Content

[0005] In order to overcome the shortcomings of existing paper punching equipment, which generally has a fixed distance between the two holes, resulting in low equipment flexibility and increased production costs, this utility model provides a paper punching device for printing that can change the punching distance.

[0006] A paper punch for printing includes a support shell, a fixed plate, a cylinder, a lower pressure block, a movable part, and a punching mold. The fixed plate is connected to the front side of the middle part of the support shell, and the cylinder is connected to the upper rear side of the support shell. The lower part of the telescopic part of the cylinder is connected to the lower pressure block. The movable part is slidably connected to the left and right sides of the lower part of the lower pressure block. The upper front and rear sides of the movable part are serrated, and the lower part of the movable part is connected to the punching mold.

[0007] In one embodiment, the device further includes a first screw, a first guide rod, and a lower pressure plate. The first screw is threadedly connected to the upper right side of the lower pressure block, and the lower pressure plate is rotatably connected to the lower side of the first screw. The first guide rod is slidably connected to the upper left side of the lower pressure block, and the lower part of the first guide rod is connected to the lower pressure plate. The lower part of the lower pressure plate has serrated front and rear sides, and the serrations on the lower part of the lower pressure plate mesh with the serrations on the upper part of the moving part.

[0008] In one embodiment, a transmission mechanism for conveying paper from a fixed plate is also included. The transmission mechanism includes a motor, a bevel gear set, a second guide rod, a second screw, a third guide rod, and a sliding plate.

Detailed Implementation

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0023] Example 1: A paper punch for printing, such as Figures 1-6 As shown, the device includes a support shell 1, a fixed plate 2, a cylinder 3, a lower pressure block 4, a moving part 8, and a punching mold 9. The fixed plate 2 is connected to the front side of the middle part of the support shell 1, and a feeding port is opened on the rear side of the fixed plate 2. The lower part of the support shell 1 is inclined. The punched paper falls from the feeding port onto the inclined surface and then falls out of the device. The cylinder 3 is fixedly connected to the upper rear side of the support shell 1. The lower part of the telescopic part of the cylinder 3 is connected to the lower pressure block 4. The moving part 8 is slidably connected to the left and right sides of the lower part of the lower pressure block 4. The upper front and rear sides of the moving part 8 are serrated. The lower part of the moving part 8 is connected to the punching mold 9. The spacing of the punching mold 9 can be adjusted by adjusting the position of the moving part 8, thereby adjusting the punching spacing of the paper.

[0024] like Figure 4 and Figure 5 As shown, it also includes a first screw 5, a first guide rod 6, and a lower pressure plate 7. The first screw 5 is threadedly connected to the upper right side of the lower pressure block 4. A handle is connected to the upper part of the first screw 5 for easy rotation. The lower pressure plate 7 is rotatably connected to the lower side of the first screw 5. The first guide rod 6 is slidably connected to the upper left side of the lower pressure block 4. The lower part of the first guide rod 6 is fixedly connected to the lower pressure plate 7. The lower part of the lower pressure plate 7 has serrated front and rear sides. The serrations on the lower part of the lower pressure plate 7 mesh with the serrations on the upper part of the moving part 8 to fix the position of the moving part 8 and prevent the moving part 8 from sliding and affecting the paper punching.

[0025] This device can be used when people need to punch holes in paper. First, place the paper to be punched flat at the back of the fixed plate 2. Start the cylinder 3 and the punching mold 9. The telescopic part of the cylinder 3 extends, causing the lower pressure block 4 to move downward. The lower pressure block 4 causes the moving part 8 and the punching mold 9 to move downward. The punching mold 9 punches holes in the paper. The punched paper falls out from the inclined surface at the bottom of the support shell 1. After punching is finished, control the telescopic part of the cylinder 3 to retract. The retraction of the telescopic part of the cylinder 3 causes the lower pressure block 4 to move upward. The lower pressure block 4 causes the moving part 8 and the punching mold 9 to move upward. Close the cylinder 3. When you want to change the punching spacing, rotate the first screw 5. The rotation of the first screw 5 causes the lower pressure plate 7 to move upward, so that the gear at the bottom of the lower pressure plate 7 and the gear at the top of the moving part 8 no longer mesh. The moving part 8 adjusts the distance between the punching dies 9 to change the punching spacing. After the distance between the punching dies 9 is adjusted, the first screw 5 is rotated in the opposite direction. The rotation of the first screw 5 drives the lower pressure plate 7 to move downward, so that the gear at the lower part of the lower pressure plate 7 and the gear at the upper part of the moving part 8 re-engage, achieving the effect of fixing the punching die 9. In this utility model, the extension of the telescopic part of the drive cylinder 3 drives the lower pressure block 4 to move downward. The lower pressure block 4 drives the moving part 8 and the punching die 9 to move downward. The punching die 9 punches holes in the paper. By rotating the first screw 5, the rotation of the first screw 5 drives the lower pressure plate 7 to move upward, so that the gear at the lower part of the lower pressure plate 7 and the gear at the upper part of the moving part 8 no longer mesh. The distance between the punching dies 9 is adjusted by the moving part 8, thus changing the punching spacing.

[0026] Example 2: Based on Example 1, such as Figure 1 , Figure 2 and Figure 6 As shown, it also includes a transmission mechanism for conveying paper from the fixed plate 2. The transmission mechanism includes a motor 10, a bevel gear set 11, a second guide rod 12, a second screw 13, a third guide rod 14, and a sliding plate 15. The motor 10 is installed inside the right side of the middle part of the support shell 1. The second guide rod 12 is rotatably connected to the right side of the front part of the support shell 1. The bevel gear set 11 is connected between the output shaft of the motor 10 and the upper part of the second guide rod 12. The second screw 13 is rotatably connected to the middle and rear part of the right side of the fixed plate 2. The bevel gear set 11 is also connected between the lower part of the second guide rod 12 and the front side of the second screw 13. The sliding plate 15 is threadedly connected to the second screw 13. The third guide rod 14 is fixedly connected to the middle and rear part of the left side of the fixed plate 2. The sliding plate 15 is slidably connected to the third guide rod 14. The lower part of the sliding plate 15 contacts the upper part of the fixed plate 2. The sliding plate 15 pushes the paper placed on the fixed plate 2 out, making it easy for people to take out the perforated paper.

[0027] When the paper is punched and needs to be removed, the motor 10 is started. The output shaft of the motor 10 rotates, driving the upper bevel gear set 11 to rotate. The upper bevel gear set 11 drives the lower bevel gear set 11 to rotate via the second guide rod 12. The rotation of the lower bevel gear set 11 drives the second screw 13 to rotate. The rotation of the second screw 13 causes the sliding plate 15 to move forward, pushing out the punched paper for easy retrieval. After the paper is removed, the motor 10 is controlled to rotate in the reverse direction. The output shaft of the motor 10 rotates in the reverse direction, driving the upper bevel gear set 11 to rotate in the reverse direction. The upper bevel gear set 11 drives the lower bevel gear set 11 to rotate in the reverse direction via the second guide rod 12. The rotation of the lower bevel gear set 11 drives the second screw 13 to rotate in the reverse direction, causing the sliding plate 15 to move backward, achieving the effect of resetting the sliding plate 15. The second screw 13 is driven by the motor 10 to rotate, causing the sliding plate 15 to move forward, pushing out the punched paper for easy retrieval.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
