Description

Technical Field

[0001] This utility model relates to the field of paper box packaging technology, and in particular to a cartoning machine with a paper box straightening mechanism. Background Technology

[0002] With the development of automated production lines and the modern packaging industry, high-speed automatic filling and packaging of cardboard boxes is necessary. Due to the thin and light nature of cardboard boxes, they are prone to tilting, misalignment, or deformation, which can even lead to product damage or packaging abnormalities. Therefore, cartoning machines with straightening mechanisms are required. These machines can automatically adjust the cardboard boxes to the correct direction and position through mechanical clamping, pneumatic control, or guiding devices, ensuring that each cardboard box is stable and accurate during filling. This achieves high efficiency, continuity, and reliability in the packaging process, meeting the stringent requirements of modern production for speed, precision, and quality.

[0003] Currently, there are various types of carton straightening and cartoning machines on the market, but these devices can usually only straighten the same type of carton. When it is necessary to straighten other types of cartons, operators often need to perform complex manual adjustments or replace relevant parts, which not only reduces production efficiency but also increases the downtime of the production line. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cartoning machine with a carton straightening mechanism.

[0005] This utility model is achieved by the following technical solution: a cartoning machine with a carton straightening mechanism, comprising a limiting mechanism, an adjusting mechanism and an auxiliary mechanism, wherein the limiting mechanism is located inside the auxiliary mechanism and the adjusting mechanism is located inside the auxiliary mechanism;

[0006] The limiting mechanism includes a housing, a limiting block slidably connected to the inner wall of the housing, a connecting plate fixedly connected to the surface of the limiting block, a limiting post slidably connected to the inner wall of the connecting plate, a spring sleeved on the surface of the limiting post, a limiting plate fixedly connected to the bottom of the limiting block, a baffle slidably connected to the surface of the limiting plate, a sliding plate fixedly connected to the bottom of the baffle, and a handle fixedly connected to the upper end of the limiting block.

[0007] Through the above technical solution, the slide can drive the baffle to slide synchronously, thereby achieving the limiting and fixing of the limiting plate, effectively preventing the limiting plate from being accidentally pulled out and reducing the risk of device failure.

[0008] As a further improvement to the above solution, the number of baffles is set to two, and the two baffles are symmetrically distributed on the left and right sides with the limiting block as the center.

[0009] Through the above technical solution, the symmetrically arranged baffles can further improve the stability of the limiting plate when it is limited, and avoid the impact caused by unnecessary shaking.

[0010] As a further improvement to the above solution, the connecting plate is located on both sides of the limiting block, the connecting plate is located inside the housing, and the spring is located at the upper end of the connecting plate.

[0011] As a further improvement to the above solution, the adjustment mechanism includes a cylinder, with a top plate fixedly connected to the upper end of the cylinder, a bottom plate fixedly connected to the lower end of the cylinder, and a push plate fixedly connected to the output end of the cylinder.

[0012] Through the above technical solution, the top plate and bottom plate can effectively fix the cylinder, ensuring the stability of the cylinder during the sliding process.

[0013] As a further improvement to the above solution, the front end of the cylinder is fixedly connected to the rear end of the housing.

[0014] As a further improvement to the above solution, the auxiliary mechanism includes a conveying component, with support frames fixedly connected to both the front and rear ends of the conveying component. A protective shell is fixedly connected to the upper end of the support frame, and a protective plate is installed at the bottom of the protective shell.

[0015] Through the above technical solution, the support frame can provide stable support for the protective shell, thereby further ensuring the stability of the cylinder inside the protective shell during operation.

[0016] As a further improvement to the above solution, the housing is located inside the protective shell, the surfaces of the top plate and the bottom plate are slidably connected to the inner wall of the protective shell, and the surface of the baffle is slidably connected to the inner wall of the protective shell.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes a limiting mechanism. Pulling the handle causes the limiting block and connecting plate to move upwards together, compressing the spring. As the limiting block moves upwards, the limiting plate also moves upwards, allowing it to slide out of the limiting groove of the protective shell and release the shell's restriction. At this point, the shell can slide freely, which in turn moves the cylinders, adjusting the distance between them. After releasing the handle, the spring causes the limiting plate on the limiting block to return to the limiting groove of the protective shell, thus fixing the shell in place. The entire device can adjust the cylinder spacing according to the needs of different types of cardboard boxes, ensuring that different cardboard boxes can be effectively uprighted, thus significantly improving the overall flexibility and stability of the device.

[0019] This utility model utilizes the cooperation of adjustment and auxiliary mechanisms. The conveying component is responsible for driving the overall transportation of the paper box, ensuring that the paper box is transferred to the target position in sequence. During the conveying process, the cylinder can push the push plate to straighten the paper box. The bottom plate and top plate can effectively limit the cylinder, thereby further ensuring the stability of the cylinder during movement. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 The cartoning machine with a carton straightening mechanism in this embodiment includes a limiting mechanism 1, an adjusting mechanism 2 and an auxiliary mechanism 3. The limiting mechanism 1 is located inside the auxiliary mechanism 3, and the adjusting mechanism 2 is located inside the auxiliary mechanism 3.

[0030] The limiting mechanism 1 includes a housing 11. A limiting block 12 is slidably connected to the inner wall of the housing 11. A connecting plate 13 is fixedly connected to the surface of the limiting block 12. A limiting post 14 is slidably connected to the inner wall of the connecting plate 13. A spring 15 is sleeved on the surface of the limiting post 14. A limiting plate 16 is fixedly connected to the bottom of the limiting block 12. A baffle 17 is slidably connected to the surface of the limiting plate 16. A sliding plate 18 is fixedly connected to the bottom of the baffle 17. A handle 19 is fixedly connected to the upper end of the limiting block 12. The sliding plate 18 can drive the baffle 17 to slide synchronously, thereby limiting and fixing the limiting plate 16, effectively preventing the limiting plate 16 from being accidentally pulled out, reducing the risk of device failure. The limiting post 14 can effectively limit the spring 15, avoiding unnecessary displacement, and further ensuring the stability of the limiting block 12.

[0031] The number of baffles 17 is set to two. The two baffles 17 are symmetrically distributed on the left and right sides with the limiting block 12 as the center. The symmetrical baffles 17 can further improve the stability of the limiting plate 16 when it is limited, and avoid the impact caused by unnecessary shaking.

[0032] The connecting plate 13 is located on both sides of the limiting block 12, inside the housing 11, and the spring 15 is located at the upper end of the connecting plate 13.

[0033] The adjusting mechanism 2 includes a cylinder 21. A top plate 22 is fixedly connected to the upper end of the cylinder 21, and a bottom plate 23 is fixedly connected to the lower end of the cylinder 21. A push plate 24 is fixedly connected to the output end of the cylinder 21. The top plate 22 and the bottom plate 23 can effectively fix the cylinder 21 to ensure the stability of the cylinder 21 during the sliding process. The push plate 24 can contact the paper box to achieve the straightening of the paper box.

[0034] The front end of cylinder 21 is fixedly connected to the rear end of housing 11.

[0035] The auxiliary mechanism 3 includes a conveying component 31. The front and rear ends of the conveying component 31 are fixedly connected to a support frame 32. The upper end of the support frame 32 is fixedly connected to a protective shell 33. A protective plate 34 is installed at the bottom of the protective shell 33. The support frame 32 can provide stable support for the protective shell 33, thereby further ensuring the stability of the cylinder 21 inside the protective shell 33 during operation. The protective plate 34 can effectively protect the slide plate 18 and avoid damage caused by external interference.

[0036] The housing 11 is located inside the protective shell 33. The surfaces of the top plate 22 and the bottom plate 23 are slidably connected to the inner wall of the protective shell 33, and the surface of the baffle 17 is slidably connected to the inner wall of the protective shell 33.

[0037] The implementation principle of a cartoning machine with a carton straightening mechanism in this embodiment is as follows: The operator pulls the limiting block 12 upward by the handle 19. At this time, the limiting block 12 can drive the connecting plate 13 to move upward together. The upward moving connecting plate 13 can squeeze the spring 15, causing it to contract. Then, the upward moving limiting block 12 can drive the limiting plate 16 to move upward together. As the limiting block 12 inside the housing 11 continues to move upward, the limiting plate 16 can eventually slide out of the limiting groove inside the protective shell 33, thereby allowing the housing 11 to release its limitation on the protective shell 33. At this time, the operator can drag the housing 11 to move. The moving housing 11 can drive the cylinder 21 to move inside the protective shell 33. The protective shell 33 has multiple limiting grooves inside. At this time, the operator can drag the housing 11 above the appropriate limiting groove, and then release the handle 19. At this time, the spring 15 will push the connecting plate 13 again due to the loss of the squeezing force, thereby driving the limiting block 12 to re-enter the interior of the housing 11 and return to the initial position. When the position is adjusted, the limiting plate 16 will slide smoothly into the limiting groove, thereby limiting and fixing the protective shell 33 and ensuring the stability of the cylinder 21. Then, the operator slides the slide plate 18 inward, which drives the baffle 17 to move synchronously, thereby limiting the limiting plate 16 and preventing it from being pulled out, further ensuring the stability of the cylinder 21. After adjusting the positions of the two cylinders 21, the external power supply is connected to start the conveying component 31. The conveying component 31 can carry the paper box. When the paper box moves to the push plate 24, the two cylinders 21 will push the push plate 24 inward synchronously to help straighten the paper box on the conveying component 31. The protective plate 34 can effectively protect the slide plate 18, thereby further ensuring the overall stability of the device during operation. The entire device can effectively adjust the distance between the two cylinders 21 according to different types of paper boxes, thereby ensuring that different types of paper boxes can be effectively straightened, further improving the overall flexibility of the device.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
