Description

Technical Field

[0002] During the printing or die-cutting process of corrugated cardboard, it is necessary to feed the corrugated paper into the printing machine or die-cutting machine piece by piece. Traditionally, the printing or die-cutting feeding of corrugated cardboard is done manually. Due to the high labor intensity and low working efficiency of manual operation, it has been gradually replaced by corresponding cardboard feeding machines. However, due to design defects, the existing cardboard feeding machines are prone to failure to feed or feeding multiple layers of cardboard at the same time, resulting in problems in the subsequent printing or die-cutting process. However, the corrugated cardboard feeding in the prior art has the following defects: 1. In the prior art, when the corrugated cardboard feeding device is feeding out the top layer of corrugated cardboard, due to the certain friction between the corrugated cardboards, the top layer of corrugated cardboard is likely to drag the lower layer of corrugated cardboards during the feeding process, and the multi-layer corrugated cardboards fed out at the same time are likely to be scrapped in the subsequent printing or die-cutting process, thereby affecting the processing of the corrugated cardboard; 2. In the prior art, the gripping mechanism in the corrugated cardboard feeding device usually uses a suction plate to deliver the top layer of corrugated cardboard.

[0034] Preferably, see Attachment Figure 1 To Attachment Fig. 9 A guide block 13 is fixedly provided on both sides of the feed port 11, and one side of the two guide blocks 13 is an inclined structure. A third stepper motor 19 is installed on one side of one of the first fixed plates 16, and the output end of the third stepper motor 19 is connected to one end of one of the rotating shafts 17. The structure of the first belt mechanism 14 is the same as that of the second belt mechanism 15. The first belt mechanism 14 is located at the lower side of the feed port 11, and the second belt mechanism 15 is located at the lower side of the discharge port 12. The height of the first belt mechanism 14 is lower than the height of the second belt mechanism 15.

[0035] Specific use of the present invention: The staff places a large amount of corrugated cardboard on the first endless belt mechanism 14, and the control system controls the extension and retraction of several electric telescopic rods 25 in the first endless belt mechanism 14. The extension and retraction of the electric telescopic rods 25 drives the rotating plate 22 to rotate, and the rotation of the rotating plate 22 drives a second movable plate 23 and two rollers 24 to move, and the outer sides of the two rollers 24 are in contact with the inner sides of the conveyor belt 18, so as to adjust the tension of the conveyor belt 18, so as to realize the regulation of the tension of the first endless belt mechanism 14, thereby improving the efficiency of loading the corrugated cardboard.

[0036] First, the control system controls the third stepper motor 19 in the first endless belt mechanism 14 to start, and the third stepper motor 19 starts to drive one of the rotating shafts 17 to rotate, and the rotation of one of the rotating shafts 17 drives the conveyor belt 18 to move, and the movement of the conveyor belt 18 causes the two rotating shafts 17 to rotate synchronously, so that the conveyor belt 18 can smoothly drive the corrugated cardboard through the feed port 11 into the box body 10. The corrugated cardboard is guided and aligned by the inclined surface of one side of the two guide blocks 13, so that a large number of corrugated cardboards are moved to the upper side of the lifting plate 53 in the center. And a large number of corrugated cardboards enter between the two first limiting plates 52, so that a large number of corrugated cardboards are limited between the two first limiting plates 52, so that the opposite sides of a large number of corrugated cardboards are aligned on the upper side of the lifting plate 53.

[0037] Secondly, the control system controls the lifting assembly to start, and the two second stepper motors 55 start to drive the two second screw rods 56 to rotate, and the outer sides of the two second screw rods 56 are respectively in threaded contact with the two second sliders 57, so that the two second sliders 57 slide upward in the two second slide grooves 54. The two second sliders 57 move upward to drive the lifting plate 53 and a large number of corrugated cardboards to move upward, and at the same time, the two second stepper motors 55 are controlled by the infrared transmitter 61 and the infrared receiver 62 to ensure that the uppermost layer of corrugated cardboard is always at a set height. The uppermost layer of corrugated cardboard is aligned with the upper end of the second limit plate 58 and the upper side of the second endless belt mechanism 15. The control system controls the telescopic rod 64 to extend and retract, and the telescopic rod 64 extends and retracts to drive the pressing plate 63 to move back and forth. The pressing plate 63 moves back and forth to cooperate with the second limit plate 58 to fix and squeeze and align the other opposite sides of the large number of corrugated cardboards, so that the large number of corrugated cardboards are aligned on the upper side of the lifting plate 53.

[0038] When the corrugated cardboard 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 downward, so that the plurality of suction cups 32 contact the uppermost corrugated cardboard. The air pump 33 starts to evacuate the gas in the movable frame 28, so that negative pressure is formed inside the movable frame 28, and the inside of the movable frame 28 is connected to the suction cup 32 through the telescopic connecting pipe 60. At this time, the negative pressure in the telescopic connecting pipe 60 and the suction cup 32 can absorb and grab the corrugated cardboard.

[0039] Next, the two hydraulic telescopic rods 30 contract and drive the first movable plate 31 and the plurality of suction cups 32 to move upward, and the plurality of suction cups 32 move upward and drive the uppermost layer of corrugated cardboard to move upward, thereby separating the uppermost layer of corrugated cardboard from the lower layer of corrugated cardboard. The two ends of the bidirectional hydraulic telescopic rod 34 contract and drive the two first slide plates 35 to approach each other, and the two first slide plates 35 approach each other and drive the two pairs of L-shaped rods 36 and clamping blocks 37 to approach each other. Each pair of clamping blocks 37 approach each other, so that the two sides of the corrugated cardboard enter the two V-shaped grooves 38 respectively, so that the two pairs of clamping blocks 37 and the V-shaped grooves 38 clamp and fix the two sides of the corrugated cardboard and limit the upper and lower positions, so as to smoothly move the uppermost layer of corrugated cardboard to the upper side of the second endless belt mechanism 15 for feeding and conveying.

[0040] Then, the two sides of the corrugated board are respectively in contact with the two pairs of rubber plates 40, and the two pairs of clamping blocks 37 continue to approach each other, thereby pushing the push rod 44 and the piston plate 45 to move. The piston plate 45 moves to allow the solution in the hydraulic chamber 59 to enter the two hollow elastic members 41 through the two connecting channels 43. The two hollow elastic members 41 expand and push the two clamping plates 39 to rotate. The rotation of the two clamping plates 39 drives the two ends of the rubber plate 40 to move and the middle of the rubber plate 40 to contact one side of the corrugated board, so that the two ends of the rubber plate 40 are bent and wrapped on one side of the corrugated board, so as to further clamp and fix the corrugated board and limit the upper and lower positions. The rotation of the two clamping plates 39 drives the two first rubber blocks 42 to approach each other, thereby clamping and fixing the upper and lower sides of the corrugated board. The piston plate 45 moves to compress the first spring 46 to generate elastic force, so that the piston plate 45 moves and resets under the elastic force of the first spring 46; and the piston plate 45 moves and resets to draw back the solution in the two hollow elastic parts 41 through the two connecting channels 43, so that the two hollow elastic parts 41 restore their shapes, so as to facilitate the rotation and reset of the two clamping plates 39, so as to continue to quickly clamp and fix the corrugated cardboard.

[0041] At the same time, the two clamping plates 39 rotate and approach each other, and the two second springs 49 drive the two movable blocks 50 to approach each other. The two movable blocks 50 approach each other and drive the two second rubber blocks 51 to approach each other. The two second rubber blocks 51 approach each other to further clamp and fix the upper and lower sides of the corrugated cardboard, so as to smoothly move the uppermost layer of corrugated cardboard to the upper side of the second endless belt mechanism 15 for feeding and transmission, and the feeding effect of the corrugated cardboard is excellent. Among them, the first slider 47 slides in the first slide groove 48, so that the movable block 50 moves smoothly. The movement of the first slider 47 compresses the second spring 49 to generate elastic force, so that under the elastic force of the second spring 49, the first slider 47 can be moved and reset, so that the corrugated cardboard can continue to be quickly clamped and fixed.

[0042] Finally, the control system controls the two first stepper motors 26 to start, and the two first stepper motors 26 start to drive the two first screw rods 27 to rotate, and the outer sides of the two first screw rods 27 are respectively in threaded contact with the two second slide plates 29, so that the two second slide plates 29 move horizontally. The horizontal movement of the two second slide plates 29 drives the movable frame 28 and the corrugated cardboard to move horizontally to the upper side of the second endless belt mechanism 15. The grabbing assembly releases the corrugated cardboard, so that the corrugated cardboard falls onto the second endless belt mechanism 15, and the second endless belt mechanism 15 starts to send the corrugated cardboard to the printing press or die-cutting machine for processing.

[0043] The present invention discloses a corrugated cardboard feeding device based on an adjustable endless belt mechanism. Through the setting of the guide block 13, the first endless belt mechanism 14 drives a large number of corrugated cardboards to enter the box body 10 through the feed port 11, and guides and aligns the corrugated cardboards through the inclined surfaces of one side of the two guide blocks 13, so that a large number of corrugated cardboards are centrally moved to the upper side of the lifting plate 53. Then, through the setting of the first limiting plate 52, a large number of corrugated cardboards enter between the two first limiting plates 52, so that a large number of corrugated cardboards are limited between the two first limiting plates 52, so that the opposite sides of a large number of corrugated cardboards are aligned on the upper side of the lifting plate 53. Finally, through the setting of the second limiting plate 58 and the pressing plate 63, the telescopic rod 64 is extended and retracted to drive 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 and squeeze and align the other opposite sides of a large number of corrugated cardboards, so that a large number of corrugated cardboards are aligned on the upper side of the lifting plate 53.

[0044] The present invention is a corrugated cardboard feeding device based on an adjustable endless belt mechanism. By setting clamping blocks 37 and V-shaped grooves 38, each pair of clamping blocks 37 are close to each other, so that the two sides of the corrugated cardboard enter the two V-shaped grooves 38 respectively, so that the two pairs of clamping blocks 37 and V-shaped grooves 38 are used to clamp and fix the two sides of the corrugated cardboard and limit the upper and lower positions, so as to smoothly move the uppermost layer of corrugated cardboard to the upper side of the second endless belt mechanism 15 for feeding and transmission. Then, through the arrangement of the clamping plates 39, the first rubber blocks 42, and the rubber sheets 40, the two sides of the corrugated paperboard are respectively in contact with the two pairs of rubber sheets 40 and the two pairs of clamping blocks 37 continue to approach each other, thereby pushing the push rod 44 and the piston plate 45 to move, and the solution in the hydraulic chamber 59 enters the two hollow elastic members 41 through the two connecting channels 43; the two hollow elastic members 41 expand and push the two clamping plates 39 to rotate, and the rotation of the two clamping plates 39 drives the two ends of the rubber sheet 40 to move and cooperate with the middle of the rubber sheet 40 to contact one side of the corrugated paperboard, so that the rubber sheet 40 is 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; and the rotation of the two clamping plates 39 drives the two first rubber blocks 42 to approach each other, thereby clamping and fixing the upper and lower sides of the corrugated paperboard. Finally, through the arrangement of the movable block 50 and the second rubber block 51, the two clamping plates 39 rotate to approach each other, and the two second springs 49 drive the two movable blocks 50 to approach each other. The two movable blocks 50 approach each other and drive the two second rubber blocks 51 to approach each other. The two second rubber blocks 51 approach each other to further clamp and fix the upper and lower sides of the corrugated cardboard, so as to smoothly move the uppermost layer of the corrugated cardboard to the upper side of the second endless belt mechanism 15 for feeding and conveying, and the feeding effect of the corrugated board is excellent.
