DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figures 1 to 4 As shown, the utility model provides a corner cutting device for corrugated paper production, which specifically includes a base 1, a centrifugal rotating rod 2, a first motor 3, a first pulley group 4, a first connecting rod 5, a corner cutting knife 6, a stopper 7 and a feeding mechanism;

[0024] Among them, a centrifugal rotating rod 2 is rotatably provided on the upper rear side of the base 1, a first motor 3 is fixedly provided on the left end of the rear side of the base 1, and a first pulley group 4 is connected to the first motor 3 and the centrifugal rotating rod 2. A certain number of first connecting rods 5 are rotatably provided on the centrifugal rotating rod 2, a corner cutting knife 6 is rotatably provided on the base 1, and the front end of the corner cutting knife 6 is rotatably matched with the first connecting rod 5, and a stopper 7 is fixedly provided on the rear side of the base 1 for quickly cutting corrugated paper;

[0025] The feeding assembly is arranged on the front side of the base 1 for fast loading and unloading of materials.

[0026] The feeding assembly includes a second connecting rod 8, an arc-shaped toothed disc 9, a wheel rod 11, a second pulley set 12 and a gear 13;

[0027] Among them, the first pulley group 4 is rotatably provided with a second connecting rod 8 away from the pulley where the motor is located, and an arc-shaped toothed disc 9 is rotatably provided at the lower end of the left side of the base 1. The arc-shaped toothed disc 9 is rotatably matched with the second connecting rod 8. Grooves 10 are equidistantly opened on the base 1 in the direction of the centrifugal rotating rod 2, and wheel rods 11 are rotatably provided in the grooves 10. Wheels are fixedly provided with equal intervals on the wheel rods 11. The top of the wheels is slightly higher than the upper surface of the base 1. A second pulley group 12 is connected between the wheel rods 11 in sequence, and a gear 13 is fixedly provided at one end of the wheel rod 11 located in the middle of all the wheel rods 11 near the arc-shaped toothed disc 9. The gear 13 cooperates with the teeth of the arc-shaped toothed disc 9 to realize the rapid loading and unloading of corrugated cardboard during operation.

[0028] In the present invention, the first pulley group 4 is driven by the rotation of the first motor 3, and the centrifugal rotating rod 2 connected to the pulley group rotates. Since the rear end of the corner cutting knife 6 is rotatably arranged on the rear side of the base 1, and the front end of the corner cutting knife 6 is rotatably connected to the lower end of the first connecting rod 5, and the upper end of the first connecting rod 5 is rotatably connected to the centrifugal rotating rod 2, when the centrifugal rotating rod 2 rotates, the middle rod position of the centrifugal rotating rod 2 changes in height regularly, so that the height of the end of the first connecting rod 5 connected to the centrifugal rotating rod 2 also changes regularly, so that the corner cutting knife 6 connected to the other end of the centrifugal rotating rod 2 The corner knife 6 has the action of cutting up and down, and can cut the corners of the corrugated paper. In addition, the block 7 can control the longitudinal position of the corrugated paper to keep the length of all the cutting angles consistent. One end of the second connecting rod 8 is connected to the larger rotating wheel of the first pulley group 4 away from the motor, and the other end is connected to the arc gear plate 9. When the radius of the arc gear plate 9 is much larger than the larger rotating wheel away from the motor, it will be found that when the rotating wheel rotates one circle, the arc gear 13 rotates forward by a certain angle, and it will be found that when the rotating wheel rotates another circle, the arc gear 13 will reverse by a certain angle. In this way, the forward and reverse rotation of the arc gear plate 9 at a certain angle can be achieved through the connecting rod mechanism. Then the gear 13 matched with the teeth can rotate forward and reverse, and the gear 13 can rotate forward and reverse with the wheel rod 11 fixed with the gear 13, so that the wheel rod 11 rotates forward when the rotating wheel rotates one circle, the centrifugal rotating disk rotates one circle, and the first connecting rod 5 drives the angle cutting knife 6 to lift upward, and the wheel rod 11 rotates reversely when the rotating wheel rotates one circle, the centrifugal rotating disk rotates one circle, and the first connecting rod 5 drives the angle cutting knife 6 to press downward. In addition, since the second pulley group 12 is connected to the wheel rods 11 in sequence, the rotation direction and speed of all the wheel rods 11 are the same. In addition, the outer surface of the wheel of the wheel rod 11 is slightly higher than the upper surface of the base 1. In summary, when the corrugated paper is placed on the upper surface of the workbench, the corrugated paper will contact the wheel of the wheel rod 11. Due to the friction between them, when the wheel reverses, it drives the corrugated paper closer to the corner cutting knife 6 until it is blocked at a suitable position by the block 7. At the same time, after the corner cutting knife 6 is pressed down to a suitable position, it contacts the corrugated paper, so that the corner cutting knife 6 can cut out angles and grooves of suitable depth. When the wheel rotates forward, it drives the corrugated paper away from the corner cutting knife 6 and leaves the surface of the workbench. At the same time, the corner cutting knife 6 is lifted up, and this reciprocating process is repeated to achieve rapid loading and unloading of corrugated paper when cutting corners.

[0029] Example 2

[0030] like Figures 2 to 4As shown, on the basis of Example 1, it also includes a first slide groove 14, a transverse baffle 15, a bolt 16, a pull plate 17, a first U-shaped column 18, a longitudinal baffle 19, a screw 20 and a second U-shaped column 21. The base 1 is parallel to the groove 10 and is evenly spaced between the grooves 10. A transverse first slide groove 14 is symmetrically opened on the front end of the base 1 in the direction perpendicular to the groove 10. A long strip hole is opened in the middle of the first slide groove 14. A transverse baffle 15 is symmetrically slidably provided on the base 1 through the transverse first slide groove 14. A bolt 16 is connected between the transverse baffle 15 and the base 1. The two transverse baffles 15 is parallel to and slideably provided with a pull plate 17 on the top of the base 1, a first U-shaped column 18 is symmetrically provided on the left and right sides of the rear side of the wheel rod 11 on the front side of the corner cutting knife 6 on the base 1, a longitudinal baffle 19 is slidably provided between the two first U-shaped columns 18, a screw 20 is penetrated and connected to the outer side surface of the lower end of the first U-shaped column 18, and the bottom surface of the screw 20 contacts the longitudinal baffle 19, and a second U-shaped column 21 is symmetrically slidably provided on the front side of the top of the base 1 through the longitudinal first slide groove 14, a shorter longitudinal baffle 19 is slidably provided between the two second U-shaped columns 21, a screw 20 is penetrated and connected to the outer side surface of the lower end of the second U-shaped column 21, and the bottom surface of the screw 20 contacts the shorter longitudinal baffle 19.

[0031] The new device can not only limit the horizontal position of the corrugated paper, but also has a hopper to realize automatic loading. Corrugated paper can be stacked between the longitudinal baffle 19 and the transverse baffle 15. However, before using the new device, it is necessary to check the position of the transverse baffle 15, check whether the spacing between the transverse baffles 15 is equal to the width of the corrugated paper and the transverse distance between the transverse baffle 15 and the corner cutting knife 6. If there is an error, loosen the bolts 16 between the base 1 and the transverse baffle 15, slide the transverse baffle 15 position, adjust the position of the transverse baffle 15 according to the width of the corrugated paper and the required corner cutting position of the corrugated paper, tighten the bolts 16, and fix the transverse baffle 15 on the base 1. If the position of the transverse baffle 15 is correct, no adjustment is required. It is also necessary to check the distance between the longitudinal baffle 19 and the upper surface of the base 1, and the distance between the baffle and The distance between the upper surfaces of the base 1 is greater than the thickness of one corrugated paper and less than the thickness of two corrugated paper. If there is an error, loosen the screws 20 provided on the first U-shaped column 18 and the second U-shaped column 21 to allow the longitudinal baffle 19 to slide. After adjusting the distance between the longitudinal baffle 19 and the upper surface of the base 1 to be slightly larger than the corrugated paper, tighten the screws 20 to fix the longitudinal baffle 19. In this way, the baffle can prevent two corrugated papers from being cut at the same time to improve the cutting accuracy and prevent the unprocessed corrugated paper from being discharged when the corrugated paper is discharged. If there is no error, no change is required. In this way, the corrugated paper can be stacked between the transverse baffle 15 and the longitudinal baffle 19, and the transverse position is limited by the transverse baffle 15 to ensure the transverse cutting accuracy of the angle cutting machine, and the number of corrugated papers entering and exiting is limited to one piece by the longitudinal block 7.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, on the basis of Example 1, it specifically includes a rotating bucket 22; a first block 24, a second block 25, a movable pin 27 and a servo motor 28. The rotating bucket 22 is rotatably provided on the upper end of the front side surface of the base 1. The cross surface of the rotating bucket 22 is a comb shape with equidistant protrusions. The vertical surface of the rotating bucket 22 is equidistantly provided with wide grooves 23. The first block 24 is rotatably provided between two symmetrical grooves 10 on the rotating bucket 22. The outer end of the first group of blocks can be magnetically attracted to the rotating bucket 22. One end of the second block 25 is rotatably connected to the outer end of the first block 24. The lower surfaces of the first block 24 and the second block 25 are provided with a wavy surface 26, and the wavy surface is higher than the protrusion where the two blocks are connected. A movable pin 27 is slidably provided on the first block 24 near the rotating bucket 22, and the movable pin 27 contacts with the rotating bucket 22. A servo motor 28 is fixedly provided on the front end of the right side of the base 1, and the servo motor 28 is fixedly connected to the rotating bucket 22.

[0033] The corrugated paper flying out of the base 1 through the forward rotation of the wheel rod 11 will be blocked by an inner block and fall into the rotating bucket 22. When the corrugated paper above the base 1 is cut, the corrugated paper on the rotating bucket 22 is full, and the cut corners are all facing the corner cutting knife 6. The staff rotates the second blocking block 25. After the angle between the first blocking block 24 and the first blocking block 24 reaches 180°, they cannot be rotated due to the influence of the vertical surface at the connection between the two blocking blocks, so that the blocking blocks are formed into longer blocking blocks. The first blocking block 24 is rotated, and the two blocking blocks are in contact with the upper surface of the stacked corrugated paper, wherein the height of the wavy surface is equal to the connection protrusion of the two blocking blocks, thus avoiding the connection protrusion of the two blocking blocks from damaging the surface of the corrugated paper, and sliding The latch causes one end of the latch to be stuck between the first block 24 and the rotating bucket 22, limiting the rotation of the block, thereby clamping the corrugated paper. The staff starts the servo motor 28 to rotate the rotating bucket 22 180° counterclockwise, so that the rotating bucket 22 carries the corrugated paper to the base 1, and the corrugated paper flips 180° at the same time. The other side of the corrugated paper to be processed is close to the position of the corner cutting knife 6, and the pull plate 17 is inserted between the two horizontal baffles 15. After the staff pushes the corrugated paper onto the pull plate 17 through the wide slot 23, the first block 24 and the second block are retracted, and the servo motor 28 is started to rotate the rotating bucket 22 back to its original position. In addition, this design can also be applied to the feeding of unprocessed cardboard.

[0034] like Figure 4 As shown, based on the first embodiment, a scale 29 is further included. The lower end of the front side surface of the first U-shaped column 18 is provided with a scale 29 .

[0035] The lower ends of the first U-shaped column 18 and the second U-shaped column 21 can be scaled 29 to facilitate the staff to adjust the height of the longitudinal baffle 19 and conduct routine equipment inspections.

[0036] like Figure 4As shown, based on the first embodiment, the tool further includes an oblique chamfer 30 , and an oblique chamfer 30 is provided on the lower side of the longitudinal baffle 19 facing the wheel rod 11 .

[0037] The longitudinal baffle 19 has an oblique guide angle 30 on the side facing the corrugated paper, so that the corrugated paper can pass smoothly under the longitudinal baffle 19 and avoid being stuck in special circumstances.

[0038] like Figure 3 As shown, on the basis of embodiment 1, the tool further includes an inclined block 31. The inclined blocks 31 are fixedly provided at both ends of the front side of the rotating bucket 22, and the horizontal surface of the inclined block 31 faces upward.

[0039] The inclined block 31 is symmetrically arranged on the left and right sides of the front side of the rotating bucket 22. The upper surface of the inclined block 31 is parallel to the upper surface of the base 1. When the rotating bucket 22 flips to 180°, the upper surface of the inclined block 31 contacts the upper surface of the base 1 to prevent the rotating bucket 22 from continuing to rotate and causing unnecessary risks.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
