A feeding device for a carton opener Technical Field

[0001] This utility model relates to the field of case opener technology, specifically a feeding device for a case opener. Background Technology

[0002] In modern logistics and packaging industries, carton erectors are key equipment in automated packaging lines. Their function is to automatically complete a series of operations, including carton picking, forming, folding, and sealing, thereby greatly improving packaging efficiency and quality. The feeding device, as an important component of the carton erector, is responsible for transporting flattened cartons from the storage area to the opening work area. Its performance and stability directly affect the overall efficiency and reliability of the carton erector.

[0003] However, in practical applications, traditional carton openers use suction cups to pick up cartons from top to bottom and then place them one by one onto the conveyor belt. Due to imperfections in the suction cup design or control system, it is often difficult to ensure stable picking up and efficient conveying of cartons, thus affecting the continuous operation of the packaging line. To address these issues, the inventors have proposed a feeding device for carton openers. Summary of the Invention

[0004] In order to solve the problem of low efficiency in the case-opening machine's method of using suction cups to pick up materials, the purpose of this utility model is to provide a feeding device for the case-opening machine.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a feeding device for a carton opener, including a mounting frame, a conveyor belt inside the mounting frame, push plates fixedly connected to the outer side of the conveyor belt at equal intervals, a placement frame fixedly connected to one side of the top of the mounting frame, cardboard boxes stacked inside the placement frame, a through groove opened on one side of the back of the placement frame, the push plates moving through the through groove, two sets of symmetrically distributed partition components on both sides of the cardboard boxes, and the height of the top surface of the push plate being less than the height of the top surface of the bottommost cardboard box.

[0006] Preferably, the partition assembly includes two partition plates that movably pass through the side of the placement frame. A fixing block is fixedly connected to one side of each partition plate, and a limiting post is fixedly connected to one side of each fixing block. Two fixing plates are fixedly connected to both sides of the placement frame and between the corresponding two partition plates. A rotating rod is rotatably connected between the two fixing plates. Both ends of the rotating rod have movable grooves. The limiting post is movably engaged in the rotating rod. An electric push rod is rotatably installed on one side of one of the fixing plates, and the piston rod of the electric push rod is rotatably connected to the rotating rod.

[0007] Preferably, baffles are fixedly connected to both sides of the top of the mounting frame and to one side of the placement frame, and the cardboard board is located between the two baffles.

[0008] Preferably, two symmetrically distributed placement plates are fixedly connected to the inner side of the mounting frame and above the conveyor belt, and the cardboard board is placed between the tops of the two placement plates.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] The conveyor belt drives the pusher plate to move horizontally, pushing out the cardboard boxes inside the placement frame one by one. The extension and retraction of the pusher piston rod drives the rotating rod to rotate. The cooperation between the movable groove and the limiting column simultaneously drives the two partition plates to move alternately in opposite directions, realizing the quantitative feeding of cardboard boxes. This avoids the cardboard boxes from stacking together, which increases the pressure on the bottom cardboard box and increases the friction between the cardboard boxes, making it difficult to push out the bottom cardboard box. This further improves the stability of the equipment operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: As shown in Figures 1-6, this utility model provides a feeding device for a carton opener, including a mounting frame 1. A conveyor belt 2 is arranged inside the mounting frame 1. Push plates 3 are fixedly connected to the outside of the conveyor belt 2 at equal intervals. A placement frame 4 is fixedly connected to one side of the top of the mounting frame 1. Carton boards 5 are stacked inside the placement frame 4. A through groove 6 is opened on one side of the back of the placement frame 4. The push plates 3 move through the through groove 6. Two sets of symmetrically distributed partition components 7 are arranged on both sides of the carton boards 5.

[0021] The partition assembly 7 includes two partition plates 71, which movably pass through the side of the placement frame 4. A fixing block 72 is fixedly connected to one side of each partition plate 71, and a limiting post 73 is fixedly connected to one side of each fixing block 72. Two fixing plates 74 are fixedly connected to both sides of the placement frame 4 and between the corresponding two partition plates 71. A rotating rod 75 is rotatably connected between the two fixing plates 74. Both ends of the rotating rod 75 are provided with movable grooves 76, and the limiting post 73 is movably engaged in the rotating rod 75.

[0022] By adopting the above technical solution, when the rotating rod 75 rotates, the cooperation between the movable groove 76 and the limiting post 73 drives the two partition plates 71 to move alternately in opposite directions. When it is necessary for the carton board 5 to fall to the bottom of the placement frame 4, the lower partition plate 71 is pulled out from the inside of the placement frame 4, while the upper partition plate 71 extends into the inside of the placement frame 4, so that the carton board 5 located between the two partition plates 71 falls to the bottom of the placement frame 4. The upper partition plate 71 is used to separate the carton board 5. This alternating operation realizes the quantitative feeding operation of the carton board 5, avoids the carton boards 5 from being stacked together, which increases the pressure on the bottom carton board 5, thereby increasing the friction between the carton boards 5 and causing the bottom carton board 5 to be difficult to push out.

[0023] An electric push rod 77 is rotatably mounted on one side of one of the fixed plates 74, and the piston rod of the electric push rod 77 is rotatably connected to the rotating rod 75.

[0024] By adopting the above technical solution, the rotation of the rotating rod 75 is achieved by extending and retracting the piston rod of the electric push rod 77.

[0025] Both sides of the top of the mounting frame 1 and one side of the placement frame 4 are fixedly connected to baffles 9, and the carton board 5 is located between the two baffles 9.

[0026] By adopting the above technical solution and setting the baffle 9, it is convenient to limit the conveying of the carton board 5 and prevent the position of the carton board 5 from deviating.

[0027] Two symmetrically distributed placement plates 8 are fixedly connected to the inner side of the mounting frame 1 and above the conveyor belt 2, and the carton board 5 is placed between the tops of the two placement plates 8.

[0028] By adopting the above technical solution and setting up the placement plate 8, it is easier to support the cardboard board 5, thereby improving the stability of equipment operation.

[0029] The height of the top surface of the push plate 3 is less than the height of the top surface of the bottom cardboard board 5.

[0030] By adopting the above technical solution, by setting the height of the top surface of the push plate 3 to be less than the height of the top surface of the bottom carton board 5, it is convenient to discharge the carton boards 5 one by one.

[0031] Working principle: When feeding carton boards 5 using the carton erector, the carton boards 5 are stacked inside the placement frame 4 and placed between the two lower partition plates 71. The extension and retraction of the piston rod of the electric push rod 77 drives the rotating rod 75 to rotate. Utilizing the cooperation between the movable groove 76 and the limiting post 73, the two partition plates 71 are simultaneously driven to move alternately in opposite directions. When it is necessary for the carton board 5 to fall to the bottom of the placement frame 4, the lower partition plate 71 is pulled out from inside the placement frame 4, while the upper partition plate 71 extends into the placement frame 4, causing the carton board 5 located between the two partition plates 71 to fall to the bottom of the placement frame 4. The upper partition plate 71 then acts as a divider for the carton board 5. This alternating operation achieves quantitative feeding of the carton boards 5, preventing the carton boards 5 from stacking together, which would increase the pressure on the bottom layer of carton boards 5, thereby increasing the friction between the carton boards 5 and making it difficult to push out the bottom layer of carton boards 5.

[0032] Then, the pusher plate 3 is driven by the conveyor belt 2 to move horizontally. When the pusher plate 3 moves to contact the bottom carton board 5, it pushes the carton board 5 out of the placement frame 4 and uses the baffle 9 to limit the movement of the carton board 5, thereby realizing the one-to-one conveying operation of the carton board 5.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
