Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of corrugated paperboard feeding, and more particularly to a corrugated paperboard feeding device based on a controllable ring belt mechanism. BACKGROUND

[0002] In the process of corrugated paper printing or die cutting, it is necessary to send the corrugated paper into the printing machine or die cutting machine one by one. The traditional corrugated paper printing or die cutting feeding is manually operated, which is labor-intensive and low in efficiency. Therefore, it has been gradually replaced by a corresponding paperboard feeding machine. However, due to the design defects of the existing paperboard feeding machine, it is prone to fail to feed or feed multiple layers of paperboard at the same time, which causes problems in the subsequent printing or die cutting process. However, the existing corrugated paperboard feeding has the following defects:

[0003] 1. In the existing technology, the corrugated paperboard feeding device is prone to drag the lower corrugated paperboard out during the feeding process of the uppermost corrugated paperboard due to the friction between the corrugated paperboards. The multiple layers of corrugated paperboard fed at the same time are prone to be scrapped during the subsequent printing or die cutting process, thereby affecting the processing of the corrugated paperboard.

[0004] 2. In the existing technology, the grabbing mechanism in the corrugated paperboard feeding device usually uses a suction disc to feed the uppermost corrugated paperboard. However, it is difficult to quickly feed the uppermost corrugated paperboard by using only the suction disc for grabbing, thereby affecting the efficiency of the corrugated paperboard feeding.

[0005] Therefore, in view of the above problems, the existing structure and defects are improved, and a corrugated paperboard feeding device based on a controllable ring belt mechanism is provided to achieve a more practical and valuable purpose. SUMMARY

[0049] The specific use method of the present application is as follows:

[0050] The staff places a large amount of corrugated paper on the first ring belt mechanism 14, the control system controls the extension and contraction of the plurality of electric telescopic rods 25 in the first ring belt mechanism 14, the electric telescopic rods 25 are driven to rotate the rotating plate 22, the rotating plate 22 is driven to move one second movable plate 23 and two rollers 24, and the outer sides of the two rollers 24 are in contact with the inner side of the conveying belt 18, so as to adjust the tension degree of the conveying belt 18, so as to realize the adjustment of the tension degree of the first ring belt mechanism 14, and the efficiency of the corrugated paper feeding is improved.

[0051] Firstly, the control system controls the third stepping motor 19 in the first ring belt mechanism 14 to start, the third stepping motor 19 is driven to rotate one of the rotating shafts 17, the rotating shaft 17 is driven to move the conveying belt 18, the conveying belt 18 is driven to rotate the two rotating shafts 17 synchronously, so as to make the conveying belt 18 stably drive the corrugated paper to pass through the feeding port 11 and enter the box body 10. The side slope of the two guide blocks 13 guides and aligns the corrugated paper, so as to make a large amount of corrugated paper move to the upper side of the lifting plate 53 in the middle. And a large amount of corrugated paper enters between the two first limiting plates 52, so as to limit the large amount of corrugated paper between the two first limiting plates 52, so as to align the opposite sides of the large amount of corrugated paper on the upper side of the lifting plate 53.

[0052] Secondly, the control system controls the lifting assembly to start, the two second stepper motors 55 drive the two second lead screws 56 to rotate, and the outer sides of the two second lead screws 56 are in threaded contact with the two second sliding blocks 57 respectively, so that the two second sliding blocks 57 slide upwards in the two second sliding grooves 54 respectively. The two second sliding blocks 57 move upwards to drive the lifting plate 53 and the corrugated paperboard to move upwards, and the infrared emitter 61 and the infrared receiver 62 are used to control the two second stepper motors 55, so as to ensure that the uppermost corrugated paperboard is always at a set height. The uppermost corrugated paperboard is aligned with the upper end of the second limiting plate 58 and the upper side of the second ring belt mechanism 15. The control system controls the telescopic rod 64 to extend and retract, and the telescopic rod 64 drives the pressing plate 63 to move back and forth, and the pressing plate 63 moves back and forth to cooperate with the second limiting plate 58 to fix the other two opposite sides of the corrugated paperboard, so as to align the corrugated paperboard on the upper side of the lifting plate 53.

[0053] When the corrugated paperboard is lifted to the set height, the control system controls the grabbing assembly to start, and the two hydraulic telescopic rods 30 extend to drive the first movable plate 31 and the plurality of suction cups 32 to move downwards, so that the plurality of suction cups 32 contact the uppermost corrugated paperboard. The air pump 33 starts to evacuate the gas in the movable frame 28, so that a negative pressure is formed in the movable frame 28, and the inside of the movable frame 28 is communicated with the suction cups 32 through the telescopic connecting pipe 60. At this time, the negative pressure in the telescopic connecting pipe 60 and the suction cups 32 can adsorb and grab the corrugated paperboard.

[0054] Then, the two hydraulic telescopic rods 30 retract to drive the first movable plate 31 and the plurality of suction cups 32 to move upwards, and the plurality of suction cups 32 move upwards to drive the uppermost corrugated paperboard to move upwards, so as to separate the uppermost corrugated paperboard from the lower corrugated paperboard. The two ends of the bidirectional hydraulic telescopic rod 34 retract to drive the two first sliding plates 35 to move close to each other, and the two first sliding plates 35 move close to each other to drive the two pairs of L-shaped rods 36 and the clamping blocks 37 to move close to each other. Each pair of clamping blocks 37 moves close to each other to make the two sides of the corrugated paperboard enter the two V-shaped grooves 38 respectively, so as to use the two pairs of clamping blocks 37 and the V-shaped grooves 38 to clamp and fix the two sides of the corrugated paperboard and limit the up and down movement of the corrugated paperboard, so as to smoothly move the uppermost corrugated paperboard to the upper side of the second ring belt mechanism 15 for feeding and conveying.

[0055] Then, the two sides of the corrugated paperboard are respectively in contact with the two pairs of rubber plates 40 and the two pairs of clamping blocks 37 continue to move close to each other, thereby pushing the top rod 44 and the piston plate 45 to move, and the piston plate 45 moves to make the solution in the hydraulic cavity 59 enter the two hollow elastic members 41 through the two connecting channels 43 respectively. The two hollow elastic members 41 expand to push the two clamping plates 39 to rotate, and the rotation of the two clamping plates 39 drives the two ends of the rubber plate 40 to move and cooperate with the middle part of the rubber plate 40 to contact one side of the corrugated paperboard, so that the two ends of the rubber plate 40 are bent and wrapped on one side of the corrugated paperboard, so as to further clamp and fix the corrugated paperboard and limit the upper and lower positions of the corrugated paperboard, and the rotation of the two clamping plates 39 drives the two first rubber blocks 42 to move close to each other, thereby clamping and fixing the upper and lower sides of the corrugated paperboard. The movement of the piston plate 45 compresses the first spring 46 to generate elastic force, so that the piston plate 45 moves back to the original position under the action of the elastic force of the first spring 46; and the movement of the piston plate 45 back to the original position draws the solution in the two hollow elastic members 41 back through the two connecting channels 43, so that the two hollow elastic members 41 restore their shapes, so as to enable the two clamping plates 39 to rotate back to the original position, thereby enabling the corrugated paperboard to be clamped and fixed quickly.

[0056] Meanwhile, the rotation of the two clamping plates 39 moves close to each other drives the two movable blocks 50 to move close to each other through the two second springs 49, the two movable blocks 50 move close to each other drives the two second rubber blocks 51 to move close to each other, the two second rubber blocks 51 move close to each other further clamps and fixes the upper and lower sides of the corrugated paperboard, so as to move the uppermost corrugated paperboard stably to the upper side of the second ring belt mechanism 15 for feeding and conveying, and the feeding effect of the corrugated paperboard is excellent. Among them, the first sliding block 47 slides in the first sliding groove 48, so that the movable block 50 moves stably. The movement of the first sliding block 47 compresses the second spring 49 to generate elastic force, so that the first sliding block 47 moves back to the original position under the action of the elastic force of the second spring 49, thereby enabling the corrugated paperboard to be clamped and fixed quickly.

[0057] Finally, the control system controls the two first stepper motors 26 to start, the two first stepper motors 26 start to drive the two first lead screws 27 to rotate, and the outer sides of the two first lead screws 27 are respectively in threaded contact with the two second sliding plates 29, thereby enabling the two second sliding plates 29 to move horizontally. The two second sliding plates 29 move horizontally drive the movable frame 28 and the corrugated paperboard to move horizontally to the upper side of the second ring belt mechanism 15. The grabbing assembly releases the corrugated paperboard, and the corrugated paperboard falls onto the second ring belt mechanism 15.
