Description

Technical Field

[0001] This utility model belongs to the field of cardboard box processing technology, specifically relating to a cardboard box processing feeding and conveying device. Background Technology

[0002] In critical links of the logistics supply chain, products are frequently exposed to risks that could lead to damage, external contamination, or quality deterioration. To effectively prevent these potential losses and ensure the safety and integrity of goods throughout their circulation, a common basic protective measure is to add a cardboard box as outer packaging in addition to the original product packaging. This cardboard box structure provides a crucial physical barrier for the contents, effectively cushioning vibrations, impacts, and compression during transportation, and blocking dust, moisture, and other contaminants, thereby preventing damage, contamination, or deterioration. At the same time, standardized cardboard box design makes warehouse stacking more stable and space-saving, facilitates loading and securing with various transport vehicles, and is compatible with forklifts and other conveyors. The operation of mechanized handling equipment such as conveyor belts involves the following steps in carton processing: First, large-sized raw cardboard is precisely cut into blanks of the required size according to preset specifications. Then, specific colors are printed on the surface of the blanks according to design requirements. Finally, the processed cardboard is shaped into the final carton structure through specific folding, gluing, or stapling processes. To improve the overall efficiency of the carton processing line, especially to solve the problem of continuous and stable supply of raw cardboard or semi-finished blanks to the processing equipment, modern production lines are generally equipped with specialized feeding and conveying devices to achieve efficient, precise, and automated feeding operations. This effectively reduces manual intervention and waiting time, and is a key link in ensuring efficient and continuous carton production.

[0003] Currently, the structural design of commonly used feeding and conveying devices lacks the ability to automatically adapt to width adjustment. This means that the device cannot autonomously and dynamically adjust the effective width of its transmission channel or load-bearing components according to the real-time changing processing requirements on the production line. This fixed width characteristic leads to significant inadequacy of adaptability in actual application scenarios. When encountering materials that exceed the preset width, it may not be able to effectively carry or smoothly transmit them. On the other hand, when facing materials with a width smaller than the device specifications, problems such as inaccurate positioning, offset, or even jamming often occur due to excessive gaps. Therefore, existing devices often cannot flexibly match diverse actual production needs, and their inherent rigid design limits the scope of application, becoming a key bottleneck restricting production efficiency and process adaptability.

[0004] Therefore, to address the problem that the existing feeding and conveying devices cannot automatically adjust their width according to the size of the cardboard, resulting in poor versatility, a cardboard box processing feeding and conveying device equipped with a movable limiting plate can be designed. Utility Model Content

[0005] To overcome the problem that existing feeding and conveying devices cannot automatically adjust different widths according to the size of the cardboard, resulting in poor versatility.

[0006] The technical solution of this utility model is as follows: a carton processing feeding and conveying device, including a support frame and an inclined plate; it also includes a movable limiting plate, the top of the support frame is fixedly connected to an inclined plate with a higher rear and lower front, the front end of the inclined plate is fixedly connected to a first fixed limiting plate, the first fixed limiting plate is fixedly connected to the inner wall of the support frame, the front side of the first fixed limiting plate is fixedly connected to two second fixed limiting plates with left and right opposite sides, the two second fixed limiting plates are slidably connected to two movable limiting plates with left and right opposite sides, the movable limiting plates are provided with grooves that match the first fixed limiting plate, and a movable component for adjusting the distance between the two movable limiting plates is fixedly connected between the two second fixed limiting plates.

[0007] Preferably, the two oppositely positioned movable limiting plates are synchronously driven by the moving component to move towards or away from each other. The two movable limiting plates can closely abut against the left and right edges of the cardboard blank placed on the inclined working plate. The first fixed limiting plate can limit the cardboard from the front to prevent the cardboard from shifting during subsequent transmission or processing.

[0008] Preferably, the moving component includes a driving component and a limiting component; the driving component provides power for the movement of the moving limiting plate, and the limiting component provides guidance for the movement of the moving limiting plate.

[0009] Preferably, the drive assembly includes a bidirectional threaded rod and a rotary motor; the bidirectional threaded rod is rotatably connected between the two second fixed limit plates, and the movable limit plate has a threaded hole that matches the bidirectional threaded rod. A rotary motor is installed on one of the second fixed limit plates, and the output end of the rotary motor is fixedly connected to the bidirectional threaded rod. The rotary motor is used to drive the bidirectional threaded rod to rotate.

[0010] Preferably, the limiting component includes a limiting post; the limiting post is fixedly connected between two second fixed limiting plates, and the movable limiting plate is movably sleeved on the outside of the limiting post.

[0011] Preferably, a support plate is provided above the inclined plate, a movable groove is provided inside the inclined plate, a movable block is slidably connected in the movable groove, and a connecting rod is fixedly connected to the rear side of the support plate, and the connecting rod is fixedly connected to the movable block.

[0013] Preferably, the support frame is fixedly connected to the mounting base on both the left and right sides, and the mounting base has two anchoring holes that are opposite to each other.

[0014] The beneficial effects of this utility model are:

[0015] By using a moving component as a power source, two oppositely positioned moving limit plates are precisely and synchronously driven to move towards or away from each other. Through this synchronous adjustment, the two moving limit plates can closely abut against the left and right edges of the cardboard blank placed on the inclined working plate, providing crucial lateral positioning and guidance for the cardboard. This prevents the cardboard from sliding laterally, deflecting at an angle, or shifting overall during subsequent transport or processing, reducing quality problems such as cutting errors and folding misalignment caused by inaccurate positioning, and effectively improving the yield rate of the final carton products.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of a cardboard box processing feeding and conveying device, including a support frame 1 and an inclined plate 2; it also includes a movable limiting plate 3. The top of the support frame 1 is fixedly connected to the inclined plate 2, which is higher at the back and lower at the front. The front end of the inclined plate 2 is fixedly connected to a first fixed limiting plate 4, which is fixedly connected to the inner wall of the support frame 1. The front side of the first fixed limiting plate 4 is fixedly connected to two second fixed limiting plates 5, which are opposite to each other. The two second fixed limiting plates 5 are slidably connected to each other, and the movable limiting plates 3 are provided with grooves 6 that match the first fixed limiting plate 4. The two second fixed limiting plates 5 are fixedly connected to a moving component for adjusting the distance between the two movable limiting plates 3. The moving component synchronously drives the two oppositely arranged movable limiting plates 3 to move towards or away from each other. The two movable limiting plates 3 can closely abut against the left and right edges of the cardboard blank placed on the inclined plate 2. The first fixed limiting plate 4 can limit the cardboard at the front to prevent the cardboard from shifting during subsequent transmission or processing.

[0025] Please see Figures 1-3 In this embodiment, the moving component includes a driving component and a limiting component. The driving component provides power for the movement of the moving limiting plate 3, and the limiting component provides guidance for the movement of the moving limiting plate 3. The driving component includes a bidirectional threaded rod 711 and a rotary motor 712. The bidirectional threaded rod 711 is rotatably connected between the two secondary fixed limiting plates 5. The moving limiting plate 3 has a threaded hole that matches the bidirectional threaded rod 711. A rotary motor 712 is installed on one side of the secondary fixed limiting plate 5. The output end of the rotary motor 712 is fixedly connected to the bidirectional threaded rod 711. The rotary motor 712 is used to drive the bidirectional threaded rod 711 to rotate. The fixed limiting plate 5 can restrict the movement of the movable limiting plate 3, preventing the movable limiting plate 3 from completely disengaging. The rotary motor 712 will drive the bidirectional threaded rod 711 to rotate. The threaded structures at both ends of the bidirectional threaded rod 711 have opposite thread directions. The two movable limiting plates 3 are threadedly connected to different threaded areas. The limiting component includes a limiting post 721. The limiting post 721 is fixedly connected between the two second fixed limiting plates 5. The movable limiting plate 3 is movably sleeved on the outside of the limiting post 721. Under the restriction of the limiting post 721, the movable limiting plate 3 threadedly connected to the outside of the bidirectional threaded rod 711 cannot rotate with the bidirectional threaded rod 711, but moves in the opposite direction.

[0026] Please see Figures 3-6In this embodiment, a support plate 8 is provided above the inclined plate 2, and a movable groove 9 is provided inside the inclined plate 2. A movable block 10 is slidably connected inside the movable groove 9. A connecting rod 11 is fixedly connected to the rear side of the support plate 8, and the connecting rod 11 is fixedly connected to the movable block 10. The support plate 8 can provide support to the rear side of the stacked cardboard. In conjunction with the first fixed limiting plate 4 and the movable limiting plate 3, it can restrict the cardboard. The movement of the movable block 10 will drive the support plate 8 to move back and forth, changing the position of the support plate 8 according to the thickness of the cardboard. A guide rod 12 is fixedly connected inside the movable groove 9, and the movable block 10... A sliding sleeve is attached to the outside of the guide rod 12, and a spring 13 is sleeved on the outside of the guide rod 12. One side of the spring 13 is fixedly connected to the moving groove 9, and the other side of the spring 13 is fixedly connected to the moving block 10. The guide rod 12 can guide the extension and retraction of the spring 13. The support plate 8 can automatically follow the weight of the cardboard itself through the spring 13. The support frame 1 has mounting bases 14 fixedly connected to both the left and right sides. The mounting bases 14 have two anchoring holes 15 that are opposite to each other. The feeding device is fixed on the plane by passing the anchor through the anchoring hole 15.

[0027] During installation, the worker first places the support frame 1 on a suitable plane, then passes the anchor through the anchor hole 15 and fixes the feeding device to the front of the processing equipment. One hand pushes the support plate 8 backward, and the other hand places the neatly stacked cardboard on the inclined plate 2. Then, the rotary motor 712 is started, which drives the bidirectional threaded rod 711 to rotate. Under the restriction of the limiting post 721, the two movable limiting plates 3, which are threadedly connected to different threaded areas, move towards the middle until they are close to both sides of the paperboard. The hand that is restricting the support plate 8 is released, and under the elastic force of the spring 13, the movable block 10 moves into the movable groove 9, causing the support plate 8 to be close to the back of the paperboard to form a limit. The robotic arm picks up the cardboard at the front. After losing the weight of the cardboard, the spring 13 will contract, causing the movable block 10 to move along the movable groove 9. The support plate 8 pushes the cardboard forward to be close to the first fixed limiting plate 4.

[0028] Through the above steps, the moving component acts as a power source, precisely and synchronously driving the two oppositely positioned moving limit plates 3 to move towards or away from each other. Through this synchronous adjustment, the two moving limit plates 3 can closely abut against the left and right edges of the cardboard blank placed on the inclined working plate 2, providing crucial lateral positioning and guidance for the cardboard. This prevents the cardboard from sliding laterally, deflecting at an angle, or shifting overall during subsequent transmission or processing, reducing quality problems such as cutting errors and folding misalignment caused by inaccurate positioning. It effectively improves the yield rate of the final carton product, thus solving the problem that existing feeding and conveying devices cannot automatically adjust different widths according to the size of the cardboard, resulting in poor versatility.
