Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper processing, in particular to a dual-servo dual-axis corrugated paper high-speed slotting machine. Background Art

[0002] There are two main types of corrugated paper slotting machines currently used in the market, one is a flat knife machine and the other is a high-speed circular knife machine.

[0003] The flat knife machine is composed of a paper feeding mechanism, a slotting mechanism, a pressing mechanism, etc. The paper feeding mechanism stops after sending the cardboard to the specified position, and the upper cutter cuts into the cardboard to complete one or part of the slotting. If the slot length is not enough, the paper feeding mechanism sends the cardboard forward for a distance, and the upper cutter presses down again to increase the slot length until the demand is met. After completing the first half of the slotting, the cardboard continues to move forward to the specified position, and then repeats the previous action to open the next slot to complete the work. The advantage of this design is that it has good versatility for the length, width and height of the cardboard. Within the rated length and width of the cardboard, any length and width of the cardboard can be completed by one machine. The disadvantage is that the production speed is slow.

[0004] The circular knife machine is mainly composed of a paper feeding structure, a wire pressing structure, and a slotting structure. The slotting structure is composed of an upper knife shaft and a lower knife shaft. The upper and lower knife shafts have 4 knife discs mounted on one shaft and rotate synchronously. The upper knife disc is equipped with 2 arc upper blades and the position can be relatively adjusted to adjust the distance between the front and rear two slots, that is, the box height. The machine uses gear transmission to synchronize the linear speed of the feeding, upper and lower wire pressing shafts, upper and lower knife disc shafts, etc. to achieve slotting. The advantage of this slotting machine is high efficiency, and the maximum linear speed can reach about 2.5m / s, but the working characteristic is that one circle of the knife shaft is to open a cardboard. When the machine opens a small cardboard, it runs empty most of the time. The gap between the front and rear two cardboards is large. At the same time, the size of the knife disc limits the distance between the two slots, that is, the box height. Therefore, when it is necessary to open cardboard with a large difference in box height, multiple machines of different models are required, which is not very versatile and increases the company's costs.

[0005] For flat knife machines, the production speed is too slow and cannot meet the production requirements of large-volume orders, while circular knife machines are not very versatile and different models of machines are required for large and small cardboards, which increases the company's costs and machine idleness. Therefore, it is necessary to design a highly versatile and efficient slotting machine. Summary of the invention

[0028] In this embodiment, the through-beam sensor is used to sense the paper head of the corrugated paper from the upper feeding roller 2 and the lower feeding roller 3, and calculate the paper tail position according to the set paperboard length.

[0029] The working principle and use process of the present invention are as follows: when in use, a plurality of corrugated paperboards are stacked on the feeding mechanism 1, waiting for the control console 22 to issue a feeding instruction. After receiving the feeding instruction, the AC motor 103 of the feeding mechanism 1 starts to feed a paperboard, and the paper head is clamped and positioned at the upper feeding roller 2 and the lower feeding roller 3. The paperboard is then synchronized with the speed of the upper feeding roller 2 and the lower feeding roller 3. After the paper head passes the upper feeding roller 2 and the lower feeding roller 3, it will be detected and positioned at the paper head position by the corresponding sensor. The position of the paper tail is calculated by the set length of the paperboard, and then enters between the rear upper knife shaft 4 and the rear lower knife shaft 5. At this time, the rear upper knife shaft 4 maintains an empty knife position and does not groove the paperboard. The paperboard continues to move forward to the middle of the pre-pressing line roller 6 and the pre-pressing line roller 7. The pre-pressing line wheel 1505 is The cardboard is pre-pressed, and the pre-pressing line roller 6 and the pre-pressing line lower roller 7 also play the role of clamping and providing power. The cardboard continues to move forward to between the front upper knife shaft 8 and the front lower knife shaft 9. The control center calculates the cardboard position, and the servo motor 16 accelerates in advance to synchronize with the speed of the front lower knife shaft 9. When the paper head reaches this position, the paper head is slotted. The cardboard continues to move forward to between the main pressing line roller 10 and the main pressing line roller 11 for pressing. The main pressing line roller 10 is a rubber roller. When the slotting position of the paper tail reaches the middle of the rear upper knife shaft 4 and the rear lower knife shaft 5, the rear upper knife shaft 4 is accelerated in advance by the servo motor 16 to synchronize with the rear lower knife shaft 5, and the knife head is aligned with the starting position to be slotted to complete the slotting. At the same time, the feeding mechanism 1 starts to feed the second cardboard and repeats the above actions.

[0030] In summary, the dual-servo dual-axis corrugated paper high-speed slotting machine has a fast slotting speed, the maximum slotting speed is 2.5m / s, the production is fast, the two slotting positions are not restricted, there is no limit on the upper limit of the cardboard length, the shortest is 450mm, and the longest is unlimited, and it also meets the requirements of high production efficiency, simple operation, saving manpower and effort, and the first fixed bearing 1402 and the second fixed bearing 1502 avoid the equipment to replace the copper block, simplify maintenance, and two independent servo motors 16 control, can hover, can be accelerated to the synchronous main axis, so that the cardboard width, that is, the length between the front and rear slots is not limited, and it has good versatility.
