Description

Technical Field

[0001] The utility model relates to the technical field of corrugated carton printing, and particularly relates to a feeding mechanism for corrugated carton printing. Background Technique

[0002] The forming process of corrugated cartons mainly includes: corrugating the corrugated base paper, laminating, printing the corrugated board in a predetermined shape, grooving and corner cutting, creasing, and bonding the corrugated board by a folding and gluing machine and a binding machine. Corrugated board has a significant increase in its application because of its light weight, low price, wide use, simple production, and the ability to be recycled or even reused. The printing process of cartons is relatively important in the production and forming process of corrugated cartons.

[0003] At present, when printing cartons, manual control is required for feeding. The whole process is complex for workers. They need to place the cartons one by one, and in addition, they also need to take into account the transportation of the cartons to the next process. The labor intensity of workers is high, which is not conducive to the mechanized and automatic production of cartons;

[0004] The existing patent (publication number: CN220548758U) discloses a feeding mechanism for corrugated carton printing. In this feeding mechanism for corrugated carton printing, the telescopic rod is controlled to expand and contract by controlling the motor. At the same time, the suction cups under the control motor, the telescopic structure and the square plate suck the cartons in the feeding box. Then, the motor controls the telescopic rod to extend and push the suction cup to drive the cartons to slide on the upper surface of the chute, so that the suction cups drive the cartons to be transported to the conveying device for a series of operations, reducing the labor burden of workers and improving the production efficiency.

[0005] In view of the above problems, the existing patent gives a solution, but it still requires workers to place the cartons to be printed into the feeding box, rather than automatically making the cartons enter the feeding box for feeding. Moreover, after a batch of cartons is used up, it cannot be automatically replenished, thus affecting the mechanized and automatic production efficiency of cartons.

[0006] Therefore, a feeding mechanism for corrugated carton printing is proposed. Utility Model Content

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0028] A corrugated cardboard box printing feeding mechanism includes a feeding frame 1. An electric conveyor belt 2 is arranged on the front side of the feeding frame 1. A controller 3 is bolted to the right side of the feeding frame 1. The controller 3 is electrically connected to the electric conveyor belt 2. A weighing assembly 4 is arranged inside the feeding frame 1. A lifting assembly 5 is arranged inside the bottom side of the feeding frame 1. The lifting assembly 5 is electrically connected to the controller 3. The lifting assembly 5 includes a bottom plate 501. The bottom plate 501 is fixedly connected to the inner side of the bottom of the feeding frame 1. An electric suction cup 6 is arranged on the top of the feeding frame 1. A second electric telescopic rod 7 is arranged on the top of the electric suction cup 6. The telescopic end of the second electric telescopic rod 7 is bolted to the top of the electric suction cup 6. A first electric telescopic rod 8 is arranged on the top of the second electric telescopic rod 7. The telescopic end of the first electric telescopic rod 8 is bolted to the top of the second electric telescopic rod 7;

[0029] The weighing assembly 4 includes a fixing plate 401, a weighing module 402 and a bearing plate 403. The fixing plate 401 is arranged inside the feeding frame 1. The weighing modules 402 are respectively bolted to the four corners of the top of the fixing plate 401. The weighing modules 402 are electrically connected to the controller 3. The bearing plate 403 is bolted to the top of the weighing modules 402.

[0030] In this embodiment: By providing a feeding frame 1, an electric conveyor belt 2, a controller 3, a weighing assembly 4, a lifting assembly 5, an electric suction cup 6, a second electric telescopic rod 7, and a first electric telescopic rod 8, the corrugated cardboard box to be printed is directly placed on the surface of the electric conveyor belt 2 by a forklift. Then, the operating electric conveyor belt 2 automatically conveys the corrugated cardboard box into the feeding frame 1. At this time, the controller 3 controls the electric conveyor belt 2 to stop running. The corrugated cardboard box that enters the feeding frame 1 falls on the bearing plate 403 of the weighing assembly 4. At this time, the weighing modules 402 at the four corners start to work, weigh the corrugated cardboard box on the bearing plate 403, and transmit the weight data to the controller 3 in real time. Then, the first electric telescopic rod 8 pushes the second electric telescopic rod 7 and makes the second electric telescopic rod 7 descend so that the electric suction cup 6 contacts the topmost corrugated cardboard box. The electric suction cup 6 is activated to adsorb the corrugated cardboard box and push the adsorbed corrugated cardboard box out of the feeding frame 1 to enter the subsequent printing process flow. When the corrugated cardboard box on the bearing plate 403 reaches a certain weight, the controller 3 issues an instruction to activate the lifting assembly 5. The lifting assembly 5 moves upward in the feeding frame 1 to lift the weighing assembly 4 upward, so that the electric suction cup 6 can absorb the corrugated cardboard box faster. Moreover, when the corrugated cardboard boxes are all taken, the weighing module 402 feeds back to the controller 3, and the lifting assembly 5 returns to its initial position. Then, the controller 3 controls the activation of the electric conveyor belt 2 to automatically convey the corrugated cardboard box into the feeding frame 1 again to continuously supply materials for subsequent printing, thus realizing the automation of cardboard box feeding and improving production efficiency.

[0031] Specifically, as Figure 5 shown, electric push rods 502 are bolted to the front side and the rear side of the top of the bottom plate 501. The electric push rods 502 are electrically connected to the controller 3.

[0032] Specifically, as Figure 5 shown, a lifting plate 503 is bolted to the telescopic end of the electric push rod 502. The top of the lifting plate 503 penetrates through the inside of the feeding frame 1. The top of the lifting plate 503 is bolted to the bottom of the fixing plate 401.

[0033] Specifically, as Figure 5 shown, buffer blocks 504 are bolted to the front side and the rear side of the bottom of the lifting plate 503. The buffer blocks 504 are made of hard rubber material.

[0034] In this embodiment: By setting the electric push rod 502, the lifting plate 503 and the buffer block 504, when the corrugated cardboard box on the bearing plate 403 reaches a certain weight, the controller 3 issues an instruction to start the electric push rod 502. The electric push rod 502 cooperates with the lifting plate 503 to lift the fixed plate 401 upward, so that the electric suction cup 6 can suck the corrugated cardboard box on the top of the bearing plate 403 faster. When the corrugated cardboard box is taken out, the weighing module 402 feeds back to the controller 3, and the electric push rod 502 carries the lifting plate 503 back to the initial position. During this process, the buffer block 504 at the bottom of the lifting plate 503 provides buffer support. Then, the controller 3 controls the start of the electric conveyor belt 2 to automatically convey the corrugated cardboard box into the feeding frame 1 again for continuous feeding for subsequent printing, thus realizing the automation of cardboard box feeding and improving production efficiency.

[0035] Specifically, as Figure 2 , Figure 3 shown, a sliding pad 9 is adhesively bonded to the top of the bearing plate 403. The sliding pad 9 is made of a metal material, and the top of the sliding pad 9 is in a smooth state.

[0036] Specifically, as Figure 2 shown, a protective pad 10 is adhesively bonded to the inner wall of the feeding frame 1. The protective pad 10 is made of elastic cotton material.

[0037] In this embodiment: By setting the sliding pad 9, the sliding performance of the surface of the bearing plate 403 can be increased, which is beneficial for the corrugated cardboard box to slide onto the surface of the bearing plate 403. By setting the protective pad 10, the corrugated cardboard box sliding into the feeding frame 1 can be protected to avoid damage caused by collision.

[0038] Specifically, as Figure 1 shown, the surface of the electric conveyor belt 2 is provided with anti-slip lines, and the anti-slip lines are in a grid shape.

[0039] Specifically, as Figure 2 shown, support blocks 11 are bolted to the four corners of the bottom side inside the feeding frame 1. The support blocks 11 are located at the bottom of the fixed plate 401, and the support blocks 11 are made of hard rubber material.

[0040] In this embodiment: By providing anti-slip lines in a grid shape on the surface of the electric conveyor belt 2, the stability of placing the corrugated cardboard box on the surface of the electric conveyor belt 2 can be increased. By setting the support blocks 11, the fixed plate 401 can be supported and buffered.

[0041] Working principle: When feeding a corrugated cardboard box for printing, the corrugated cardboard box to be printed is directly placed on the surface of the electric conveyor belt 2 by a forklift. Then, the operating electric conveyor belt 2 automatically conveys the corrugated cardboard box into the feeding frame 1. At this time, the controller 3 controls the electric conveyor belt 2 to stop running. The corrugated cardboard box that enters the feeding frame 1 falls on the bearing plate 403 of the weighing assembly 4. At this time, the weighing modules 402 at the four corners start to work, weigh the corrugated cardboard box on the bearing plate 403, and transmit the weight data to the controller 3 in real time. Then, the first electric telescopic rod 8 pushes the second electric telescopic rod 7 and makes the second electric telescopic rod 7 lower until the electric suction cup 6 contacts the topmost corrugated cardboard box. The electric suction cup 6 is activated to adsorb the corrugated cardboard box and push the adsorbed corrugated cardboard box out of the feeding frame 1, enabling it to enter the subsequent printing process flow. When the corrugated cardboard box on the bearing plate 403 reaches a certain weight, the controller 3 issues an instruction to activate the electric push rod 502. The electric push rod 502 cooperates with the lifting plate 503 to lift the fixing plate 401 upward, so that the electric suction cup 6 can more quickly suck the corrugated cardboard box on the top of the bearing plate 403. When the corrugated cardboard box is taken out, the weighing module 402 feeds back to the controller 3, and the electric push rod 502 carries the lifting plate 503 back to the initial position. During this process, the buffer block 504 at the bottom of the lifting plate 503 provides buffer support. Then, the controller 3 controls the activation of the electric conveyor belt 2 to automatically convey the corrugated cardboard box into the feeding frame 1 again to continuously supply materials for subsequent printing, thus realizing the automation of cardboard box feeding and ensuring the continuity and high efficiency of printing feeding, thereby greatly improving the mechanical automatic production efficiency of cardboard boxes.

[0042] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
