[0002] Corrugated cardboard originated in the late 18th century. In the early 19th century, its application increased significantly due to its light weight, low price, wide range of uses, simple production, and ability to be recycled and even reused. By the early 20th century, it had been widely popularized, promoted and applied for packaging of various commodities. Since packaging containers made of corrugated cardboard have unique properties and advantages in beautifying and protecting the goods inside, they have achieved great success in the competition with various packaging materials. It has become one of the main materials for making packaging containers that has been used for a long time and has shown rapid development.
[0003] The processing of corrugated cardboard is diverse. It is cut into appropriate lengths according to customer needs. Corrugated paper strip cutting machines are usually used to cut corrugated paper. Conveyor rollers are usually used to continuously feed corrugated cardboard feed, and a cutter is used to quickly cut the strips. However, this method will cause burrs on the edges of the cut cardboard, and the cutting effect is not good. In order to overcome this problem, the prior art uses a servo system to control the conveying frequency of the conveyor roller, so that when the cutter falls, the conveyor roller no longer conveys the corrugated cardboard, which effectively avoids the appearance of burrs on the corrugated cardboard after cutting. However, the servo motor is expensive, and its supporting driver and controller are expensive, and the maintenance cost is high, which makes the corrugated paper cutting cost too high, and the factory's income is also reduced.

[0022] Please refer to 1-4, a corrugated paper edge banding and cutting device, including: a mounting frame 1, on which a driving shaft 2, a first driven shaft 31, and a roller 4 are rotatably arranged, two ends of the driving shaft 2 are respectively fixedly sleeved with a toggle plate 21, and the toggle plate 21 has three toggle rods 22 in a circular array, a fixed block 8 is fixedly connected to the mounting frame 1, a paper feed roller 3 is fixedly sleeved on the outside of the first driven shaft 31, and an abutment rod 32 is movably sleeved on the outer sides of the two ends of the first driven shaft 31, one end of the abutment rod 32 is connected to the fixed block 8 through a tension spring 33, and six abutment blocks 34 are arranged in a circular array on both sides of the paper feed roller 3, a second round rod 322 is fixedly connected to the abutment rod 32, and the outside of the second round rod 322 is connected to an abutment sleeve 323 through a torsion spring 7, when the driving shaft 2 rotates, the toggle rod 22 pushes the abutment rod 32 to make the paper feed roller 3 rotate intermittently.
[0023] Specifically, a motor 6 is installed on the mounting frame 1, and the output shaft of the motor 6 is fixedly connected to the driving shaft 2 through a reducer. The paper feed roller 3 is a hollow cylinder in the middle, and the paper feed roller 3 is fixedly sleeved on the first driven shaft 31. Both ends of the first driven shaft 31 are connected to the mounting frame 1 through bearings. The purpose of setting the bearings is undoubtedly to reduce friction. The installation method and working principle of the bearings are common knowledge known to the staff in this field, and no further explanation is given here. The toggle rod 22 is locked on the toggle plate 21 by a screw, and the abutment sleeve 323 is rotatably sleeved on the second round rod 322, and The abutment sleeve 323 is connected by the torsion spring 7 so that the abutment sleeve 323 has a reset function. The utility model drives the paper feed roller 3 to do intermittent motion by rotating the driving shaft 2, so that the corrugated board clamped between the paper feed roller 3 and the roller 4 is intermittently output, and sufficient time is reserved for cutting the corrugated board, so that the port of the corrugated board after cutting is free of burrs, and the cutting effect of the corrugated board is improved. Compared with the prior art that uses a servo control system to control the cutting of corrugated paper, the equipment cost is saved, and the device has a simple structure, is more stable for long-term driving, and has low later maintenance costs, which greatly reduces the cost of corrugated board cutting.
[0024] Furthermore, a first round rod 321 is fixedly connected to one side of the abutting rod 32 , one end of the tension spring 33 is fixedly connected to the first round rod 321 , and the other end of the tension spring 33 is fixedly connected to the fixing block 8 .
[0025] Specifically, refer to Figure 3 The first round rod 321 is connected to the fixed block 8 so that the tension spring 33 does not hinder the contact between the toggle rod 22 and the abutment rod 32, thereby ensuring that when the toggle rod 22 pushes the abutment rod 32, the paper feed roller 3 can rotate.
[0026] Furthermore, a straight slot 11 is provided on the mounting frame 1, a slider 5 is slidably provided in the straight slot 11, and the end of the drum 4 is connected to the slider 5 via a bearing.
[0027] Specifically, refer to Figures 1 to 3 A straight slot 11 is provided on both sides of the mounting frame 1, and the drum 4 is a drum with a hollow center. The drum 4 is fixedly sleeved on the second driven shaft 41, and the two ends of the second driven shaft 41 are respectively connected to the two sliders 5 through bearings. Here, the two ends of the drum 4 can also be directly connected to the two sliders 5 through bearings.
[0028] Furthermore, a fixing seat 52 is provided on the side of the mounting frame 1 , a screw rod 51 is spirally connected inside the slider 5 , both ends of the screw rod 51 are connected to the fixing seat 52 through bearings, and an anti-slip sleeve 53 is fixedly sleeved outside one end of the screw rod 51 .
[0029] Specifically, two fixed seats 52 are provided on both sides of the mounting frame 1, and the two ends of the screw rod 51 are rotatably set in the fixed seats 52. By twisting the anti-skid sleeve 53, the screw rod 51 is rotated in place, and the slider 5 moves on the screw rod 51 to achieve the sliding of the slider 5 in the up and down directions in the straight groove 11 to adjust the height of the roller 4, so that the gap between the paper feeding roller 3 and the roller 4 is changed to adapt to corrugated cardboards of different thicknesses. The anti-skid sleeve 53 is set to increase friction to facilitate the staff to rotate the screw rod 51.
[0030] In this utility model, reference is made to Figures 1 to 4 First, the anti-slip sleeve 53 is rotated to make the slider 5 slide in the straight slot 11 to adjust the gap between the paper feed roller 3 and the roller 4, and then the specified corrugated paper is inserted between the paper feed roller 3 and the roller 4, and the motor 6 is started. As the motor 6 drives the drive shaft 2 to rotate, the three toggle rods 22 abut against the abutment rod 32 in sequence. When the toggle rod 22 abuts against the abutment rod 32 and rotates, the tension spring 33 is stretched, and the abutment sleeve 323 abuts against the abutment block 34. At this time, the toggle rod 22 can drive the paper feed. The roller 3 rotates, and when the toggle rod 22 is disengaged from the abutment rod 32, under the action of the elastic pulling force of the fixed block 8, the abutment rod 32 rotates in the opposite direction, and the abutment sleeve 323 abuts against another abutment block 34, overcomes the torsion of the torsion spring 7 and then rotates, so that the abutment sleeve 323 and the abutment block 34 are no longer abutted, and the abutment rod 32 returns to its original position. At this time, there is still a certain time before the next toggle rod 22 pushes the abutment rod 32. At this time, the cutting machine cuts the corrugated cardboard, so that the cut of the corrugated cardboard is smooth and free of burrs.
[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
