Description

Technical Field

[0001] The utility model relates to the technical field of paper product processing equipment, in particular to a punching device for paper product manufacturing. Background Art

[0002] There are various paper processing equipment. In the processing of some papers, punching is an important processing link. Usually, in order to improve efficiency, the operator will stack the papers and then punch holes through the punching device. However, because the size of the receiving slot is exactly the same as the size of the paper, when the paper is placed in the receiving slot, it is impossible to directly stuff the four sides of the whole stack of paper into the receiving slot at the same time. The operator will first put a stack of paper into the receiving slot in an inclined posture so that one side is aligned with the edge of the receiving slot, and then put the other symmetrical side into the receiving slot. At this time, the end of the paper placed later will be tilted upward, resulting in uneven stacking of the papers. After the punching device finishes punching, the hole positions on the paper do not correspond, affecting subsequent operations. In the prior art, after the cylindrical hole cutter on the paper product punching device cuts the paper at the hole position, the paper will remain inside the cylindrical hole cutter, reducing the cutting depth of the cylindrical hole cutter, affecting the subsequent punching of the paper by the cylindrical hole cutter.

In this way, under the reciprocating pulling of the second L-shaped plate, the second airbag continuously inhales and blows out air to blow the paper, causing the paper to vibrate under the blowing of the air until all the paper is leveled, thereby avoiding the problem that when the top block pushes the second L-shaped plate to move forward through the protrusion, the distance between the first L-shaped plate and the second L-shaped plate is greater than the length of the paper, causing the end of the paper to sag, and when the spring telescopic rod one in the stretched state contracts through its own elastic force and pulls the second L-shaped plate to move backward and reset, there is a problem that the drooping end of the paper is clamped between the first L-shaped plate and the second L-shaped plate.

[0012] The utility model pushes the connecting plate 2 and the cutter to continue to move downward by the push rod 2, so that the connecting plate 2 squeezes the air bag 1, and the air in the air bag 1 is sprayed into the cutter through the connected pipe, and the paper cut in the cutter is blown out into the collection frame by the sprayed air, thereby avoiding the problem that because the cutter is a cylindrical hole cutter, when the cutter cuts the corresponding position on the paper, the cut paper will be stuck in the cutter, thereby reducing the cutting depth of the cutter and affecting the subsequent punching operation of the paper.

[0027] The clamping unit includes a push rod 3 20 and a long plate 21; the push rod 3 20 is bolted to the workbench 1; and the telescopic part of the push rod 3 20 is fixedly connected to the long plate 21.

[0028] It also includes a blowing unit; the blowing unit includes an airbag 17 and a U-shaped tube 18; an airbag 17 is fixedly connected to the bottom of the front side of the L-shaped plate 2, all the airbags 17 are self-priming airbags, and the air intake and air outlet are both one-way valve structures; the airbag 17 is fixedly connected to and connected to a plurality of U-shaped tubes 18, and the air outlets of all the U-shaped tubes 18 are facing rearward.

[0029] Here is how the above example works:

[0030] First, the push rod 1 5 and the push rod 2 13 are connected to an external power supply; then, the operator puts the stack of paper to be punched on the L-shaped plate 1 2, but because the size of the receiving slot is the same as the size of the paper, when the paper is put into the receiving slot, the end of the paper will be tilted upward, resulting in uneven stacking of the paper. After the punching device finishes punching, the positions of the holes on the paper do not correspond, affecting subsequent operations;

[0031] When the operator puts the stacked paper into the L-shaped plate 2, the connecting plate 6 and the pressure plate 7 which are initially located on the right side of the collecting frame 4 are pushed to the left by controlling the push rod 5, so that the pressure plate 7 drives the top block 9 to enter the slide groove 2 3a synchronously, so that the top block 9 will contact the protrusion 10. As the push rod 15 continues to push the pressure plate 7 and the top block 9 to move to the left in the slide groove 2 3a, the top block 9 will support the end of the protrusion 10, so that the protrusion 10 will be pushed out to the front side by the top block 9, so that the top block 9 drives the L-shaped plate 23 to move forward along the slide groove 1a, so that the spring telescopic rod 19 between the L-shaped plate 23 and the L-shaped plate 2 is stretched. When the end of the top block 9 contacts the end of the protrusion 10, it is the maximum movement distance of the L-shaped plate 23. At this time, the distance between the L-shaped plate 2 and the L-shaped plate 23 is greater than the length of the paper, so that the end of the paper is tilted upward When the push rod 15 continues to push the pressure plate 7 and the top block 9 to move to the left, when the end of the top block 9 is separated from the end of the protrusion 10, the spring telescopic rod 19 in the stretched state contracts by its own elastic force, pulling the L-shaped plate 23 to move backward and reset, so that the L-shaped plate 23 pushes the uneven paper to move backward, and so on, so that the L-shaped plate 23 reciprocates to push the front end of the stacked paper, so that the stacked paper is pushed backward by the L-shaped plate 23 all the time, and all the stacked paper is pushed to be flush, until the left side of the pressure plate 7 is aligned with the left side of the L-shaped plate 12 and the L-shaped plate 23, and stops, avoiding the problem that the end of the paper will be tilted upward when the paper is put into the receiving slot because the size of the receiving slot is the same as the size of the paper, resulting in uneven paper stacking, and after the punching device finishes punching, the hole positions on the paper do not correspond, affecting subsequent operations;

[0032] However, when the top block 9 pushes the L-shaped plate 23 to move forward through the protrusion 10, the distance between the L-shaped plate 12 and the L-shaped plate 23 is greater than the length of the paper, causing the end of the paper to sag. When the spring telescopic rod 19 in the stretched state contracts through its own elastic force and pulls the L-shaped plate 23 to move backward and reset, there is a problem that the drooping end of the paper sags excessively and is then clamped between the L-shaped plate 12 and the L-shaped plate 23.

[0033] Therefore, when the top block 9 pushes the L-shaped plate 23 to the front side through the protrusion 10, the L-shaped plate 23 will pull the airbag 2 17 to move to the front side, so that the airbag 2 17 sucks air through the air inlet of the airbag 2 17 under the pulling of the L-shaped plate 23, and when the spring telescopic rod 19 in the stretched state contracts through its own elastic force and pulls the L-shaped plate 23 to move backward and reset, the L-shaped plate 23 will squeeze the airbag 2 17, so that the air in the airbag 2 17 is blown out from the U-shaped tube 18 to the front end of the paper, so that the paper moves in the direction away from the U-shaped tube 18 under the blowing of the air in the airbag 2 17. Under the reciprocating pulling of the L-shaped plate 23, the airbag 217 continuously inhales and blows out air to blow the paper until all the paper moves and briefly tilts upward when blowing air, thereby avoiding the problem that when the top block 9 pushes the L-shaped plate 23 to move forward through the protrusion 10, the distance between the L-shaped plate 12 and the L-shaped plate 23 is greater than the length of the paper, causing the end of the paper to sag, and when the spring telescopic rod 19 in the stretched state contracts by its own elastic force and pulls the L-shaped plate 23 to move backward and reset, there is a problem that the drooping end of the paper is clamped between the L-shaped plate 12 and the L-shaped plate 23;

[0034] When the left side of the pressing plate 7 is aligned with the left edges of the L-shaped plate 1 2 and the L-shaped plate 2 3, the L-shaped plate 3 11 is driven by the pressing plate 7 so that the front side of the L-shaped plate 3 11 fits with the rear side of the straight plate 12, and the L-shaped plate 1 2 and the L-shaped plate 2 3 are locked, so that the paper between the L-shaped plate 1 2 and the L-shaped plate 2 3 is more stable when punching. At this time, the round hole 2 7a is aligned with the round hole 1 2a, and the control push rod 3 20 pushes the long plate 21 to move downward, so that the long plate 21 presses the pressing plate 7 downward. The pressing plate 7 drives the top block 9 to move downward into the vertical groove 3b, limiting the slight movement of the L-shaped plate 2 3 in the left and right directions. At the same time, under the pressure of the long plate 21, the pressing plate 7 is attached to the uppermost layer of the paper, and the paper is pressed and fixed by the pressing plate 7. Then, the connecting plate 2 14 and the cutter 16 are pushed downward by controlling the push rod 2 13, so that the cutter 16 passes through the circular hole 2 7a, the circular hole 1 2a and the hole on the L-shaped plate 2 3, so that the cutter 16 opens the required hole at the corresponding position on the paper.

[0035] However, because the cutter 16 is a cylindrical hole cutter, after the cutter 16 cuts the corresponding position on the paper, the cut paper will be stuck in the cutter 16, thereby reducing the cutting depth of the cutter 16, affecting the subsequent punching operation on the paper;

[0036] The push rod 2 13 pushes the connecting plate 2 14 and the cutter 16 to continue to move downward, so that the connecting plate 2 14 squeezes the airbag 15, and the air in the airbag 15 is sprayed into the cutter 16 through the connected pipe, and the paper cut in the cutter 16 is blown into the collection frame 4 by the sprayed air, thereby avoiding the problem that the cutter 16 is a cylindrical hole cutter, and the cut paper will be stuck in the cutter 16 after the cutter 16 cuts the corresponding position on the paper, thereby reducing the cutting depth of the cutter 16 and affecting the subsequent punching operation of the paper. Subsequently, the push rod 2 13 and the push rod 3 20 pull the relevant parts to move upward and reset, and the push rod 1 5 pulls the relevant parts to move and reset, and then the operator replaces a batch of paper, and repeats the above operation to complete the punching operation of the paper.

[0037] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
