Description

Technical Field

[0001] This utility model relates to the technical field of automatic packaging production line equipment, and in particular to a multi-specification cardboard conveying device. Background Technology

[0002] In the logistics sector, especially e-commerce logistics, the demand for product packaging has increased dramatically due to the massive volume of goods. Cardboard packaging plays a crucial role in logistics transportation and product protection due to its advantages such as ease of processing and customization, environmental friendliness and recyclability, lightweight design, and low cost. Automated packaging lines typically include devices for cardboard feeding, cardboard conveying, cardboard creasing and cutting, and cardboard folding. Given the diverse range of goods, different cardboard specifications are often required to produce different types of cartons; therefore, multi-channel conveying systems are needed for cardboard delivery.

[0003] Utility model patent CN213947560U discloses a feeding device for packaging cardboard, including a feeding platform and feeding rollers. The feeding rollers drive the packaging cardboard forward on the feeding platform through rotational friction. This solution achieves multi-specification cardboard feeding in two ways: first, multiple sets of feeding rollers are horizontally arranged on a single feeding platform; second, multiple feeding platforms are arranged vertically, sharing a single discharge end. Both methods are complex in construction and occupy a large space. Furthermore, in the second method, because multiple platforms share a single discharge end, a height difference occurs between some feeding platforms and the discharge end, causing the cardboard to move at an angle along the conveying path, potentially leading to paper jams or unnecessary creases at the discharge end. Utility Model Content

[0004] Technical objective: In order to overcome the shortcomings of the existing technology, this utility model provides a multi-specification cardboard conveying device to realize the smooth horizontal conveying of cardboard of different specifications.

[0005] Technical solution: To achieve the above objectives, this utility model discloses a multi-specification cardboard conveying device, including a moving mechanism and several sets of paper feeding mechanisms disposed on the moving mechanism. The moving mechanism includes a moving frame, which drives the paper feeding mechanisms to move along the slide rail under the drive of the moving drive component.

[0006] Furthermore, several slide rails are provided, all of which are mounted on the frame.

[0007] Furthermore, the mobile drive assembly includes a mobile drive motor, the output end of which drives a mobile synchronous belt to reciprocate in a circular motion via a transmission wheel, and the mobile frame is connected to the mobile synchronous belt.

[0008] Furthermore, the paper feeding mechanism includes a paperboard platform and a roller assembly. The input end of the paperboard platform is equipped with a detection component for real-time detection of paperboard tension and automatic triggering of the paperboard feeding signal.

[0009] Furthermore, the roller assembly includes a roller drive motor, a driving roller, a driven roller, and a roller timing belt disposed on the driving roller and the driven roller.

[0010] Furthermore, the roller assembly also includes a plurality of support rollers, from which the cardboard is conveyed between the roller timing belt and the support rollers.

[0011] Furthermore, the edge of the cardboard platform is provided with a bent edge along the cardboard feeding direction to limit the cardboard conveying.

[0012] Furthermore, the detection component includes a slide bar and a photoelectric detector capable of detecting the movement of the slide bar. An inclined slot is provided on the bent edge, and both ends of the slide bar pass through the slot and can move therein.

[0013] Furthermore, the paper feeding mechanism is provided in two sets arranged vertically.

[0014] Furthermore, the active roller, driven roller, roller timing belt, and support roller are symmetrically arranged in two sets, and the two active rollers rotate synchronously through a connecting shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model relates to a multi-specification cardboard conveying device. By arranging several sets of paper feeding mechanisms on a vertically movable mechanism, the height of the cardboard platforms of different sets of paper feeding mechanisms is always consistent with the height of the subsequent cardboard creasing and cutting device during cardboard conveying, achieving smooth horizontal conveying of cardboard of different specifications. Furthermore, by installing a detection component on the paper feeding mechanism, the cardboard tension can be detected in real time, and a cardboard feeding signal can be automatically triggered when a specific type of cardboard needs to be fed. This cardboard conveying device has a simple structure and achieves automated and smooth conveying of cardboard of different specifications. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0025] like Figure 1 and Figure 4 As shown, a multi-specification cardboard conveying device is used in a packaging box packing production line and is installed between the cardboard feeding device 1 and the cutting and creasing device 2. It includes a moving mechanism, several sets of paper feeding mechanisms mounted on the moving mechanism, and a frame 3. Slide rails 5 are installed on the columns of the frame 3, and the moving mechanism is located inside the frame 3. The moving mechanism includes a moving frame 4, which, driven by a moving drive assembly, moves the paper feeding mechanisms along the slide rails 5. Specifically, the frame 3 is a cuboid frame structure with four columns. Several slide rails 5, preferably four, are vertically mounted on the four columns. The moving frame 4 is also a cuboid frame structure, with sliders 20 fixedly connected to the four corners of its top. The four sliders 20 move along the four slide rails 5, causing the moving frame 4 to rise and fall, thereby achieving the lifting and lowering of the paper feeding mechanisms.

[0026] like Figure 1As shown, the moving drive assembly includes a moving drive motor 6, transmission wheels, and a moving synchronous belt 7. The transmission wheels include driving and driven transmission wheels located at both ends of the moving synchronous belt 7. The driving transmission wheel is located at the output end of the moving drive motor 6, and the output end of the moving drive motor 6 drives the moving synchronous belt 7 to reciprocate in a circular motion via the transmission wheel. Specifically, there are two driving and driven transmission wheels and two moving synchronous belts 7, symmetrically arranged at both ends of the frame 3. The two driving transmission wheels rotate synchronously via a transmission shaft 21. Specifically, a moving frame 4 is positioned between the two moving synchronous belts 7. Claws 22 are provided on the crossbeams at both ends of the moving frame 4, and the moving frame 4 is fixedly connected to the moving synchronous belt 7 using the claws 22. When the moving synchronous belt 7 reciprocates, it drives the moving frame 4 to rise and fall.

[0027] like Figure 2 and Figure 3 As shown, the paper feeding mechanism includes a cardboard platform 8 and a roller assembly. The cardboard fed by the cardboard feeding device 1 is conveyed along the cardboard platform 8 to the cutting and creasing device 2 under the drive of the roller assembly. Several sets of paper feeding mechanisms can be set on the movable frame 4, and the width of the cardboard platform 8 in each set of paper feeding mechanisms can be determined according to the different cardboard widths.

[0028] The input end of the cardboard platform 8 is equipped with a detection component for real-time detection of cardboard tension and automatic triggering of a cardboard feeding signal to notify the cardboard feeding device 1 to start feeding. The edge of the cardboard platform 8 is provided with a bending edge 14 along the cardboard feeding direction to limit the cardboard conveying. Specifically, the detection component includes a slide bar 15 and a photoelectric detector 16 capable of detecting the movement of the slide bar 15. The bending edge 14 is provided with an inclined slot 17, through which both ends of the slide bar 15 pass and can move. When paper needs to be fed, the roller assembly drives the cardboard to move along the cardboard platform 8. At this time, the cardboard tension increases, and during the straightening and tensioning process, the cardboard contacts the slide bar 15 and generates an upward thrust, pushing the slide bar 15 to move along the slot 17. After the photoelectric detector 16 detects the slide bar 15, it triggers the cardboard feeding signal to notify the cardboard feeding device 1 to start feeding.

[0029] The roller assembly includes a roller drive motor 9, a driving roller 10, a driven roller 11, a roller timing belt 12, and several support rollers 13. The output end of the roller drive motor 9 is connected to the driving roller 10 to drive its rotation. The driving roller 10 and the driven roller 11 are located at opposite ends of the roller timing belt 12. The roller timing belt 12 and the several support rollers 13 are all arranged along the paperboard feeding direction, and the paperboard is conveyed between the roller timing belt 12 and the support rollers 13. Specifically, two sets of driving rollers 10, driven rollers 11, roller timing belt 12, and support rollers 13 are symmetrically arranged, and the two driving rollers 10 are connected by a connecting shaft 18 to achieve synchronous rotation.

[0030] Appendix Figure 6The paper feeding mechanism is arranged in two vertically aligned sets. When a certain size of cardboard is needed, the movable frame 4 moves the paper feeding mechanism up and down, so that the paper feeding platform 8 containing the required cardboard size is horizontally aligned with the cutting and creasing platform 19 on the cutting and creasing device 2. The cardboard's transport path is on a horizontal plane, significantly improving the smoothness of cardboard transport. When the cardboard size needs to be changed, simply adjust the height of the movable frame 4 again to horizontally align the paper feeding platform 8 containing the corresponding cardboard size with the cutting and creasing platform 19.

[0031] In other operating conditions, if the moving frame 4 needs to be aligned with the paper feeding platform 8 and the cutting and creasing platform 19 by moving horizontally, then it is necessary to adjust the setting direction of the slide rail 5 and the driving direction of the moving drive component, arrange the paper feeding mechanism horizontally, and make adaptive adjustments to other components.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
