Description

Technical Field

[0001] This utility model relates to the technical field of box openers, and more particularly to a feeding mechanism for a box opener. Background Technology

[0002] In automated packaging production lines, case erectors are key pieces of equipment. Their main function is to unfold initially folded cardboard into cartons for subsequent packing and sealing processes. In traditional case erector systems, the cardboard feeding and conveying process often relies on motor-driven power transmission devices, using chains, rollers, or belts to transport stacked cardboard to predetermined positions. However, this power-driven conveying method is not only structurally complex and costly to manufacture, but also requires additional power during operation, resulting in frequent maintenance and hindering system simplification and energy consumption control.

[0003] Especially in applications requiring high equipment stability and reliability, power conveying systems are prone to downtime due to transmission errors, electrical control malfunctions, or paper jams, impacting overall production cycle time. Furthermore, traditional conveying structures are poorly adaptable and inconvenient to adjust when handling different sized cardboard pieces, failing to meet the demands of multi-specification product co-production. Therefore, there is an urgent need for a new type of feeding and conveying mechanism that is simple in structure, highly adaptable, and has low maintenance costs to improve the overall operating efficiency and stability of the case erector system.

[0004] While some non-powered conveying structures have been proposed in existing technologies, most rely on tilting gravity sliding or manual propulsion, which still suffer from problems such as unstable conveying, easy tipping of stacked cardboard, and inaccurate positioning. These issues fail to meet the demands of automated applications requiring high continuity and precision in conveying. Especially when dealing with large batches of stacked cardboard, how to stably and efficiently convey the cardboard to subsequent mechanisms has become a significant technical bottleneck for the industry.

[0005] In view of this, the inventor has designed a feeding mechanism for a box-opening machine, which leads to this invention. Utility Model Content

[0011] In a further embodiment, the hollow sleeve is fixedly equipped with a handle that facilitates movement and positioning by the operator.

[0012] In a further embodiment, baffles are symmetrically arranged on both sides of the synchronous belt conveyor to improve the stability of cardboard conveying.

Detailed Implementation

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] like Figure 1 , Figure 2 and Figure 5As shown, this utility model relates to a feeding and conveying mechanism suitable for a carton erector, mainly used to transport folded but not unfolded cardboard to subsequent processes in an orderly and stable manner, realizing automatic feeding of cardboard. This structure adopts a powerless conveying design concept, achieving the pushing and positioning of cardboard through the linkage and coordinated movement of mechanical structures without the need for a motor or external drive system. It features a simple structure, low energy consumption, stable operation, and strong adaptability.

[0022] As shown in one embodiment, the feeding and conveying mechanism mainly includes: a synchronous belt conveying assembly 1, a guide rail 2, a pushing device 3, a driving structure 33, and a blocking assembly 34.

[0023] The synchronous belt conveyor assembly 1 is used to carry stacked cardboard and provide a basic conveying path for the cardboard. The synchronous belt conveyor assembly 1 includes a support frame 11 and a synchronous belt conveyor line 12 mounted on the support frame 11. The conveyor line is arranged horizontally along a predetermined direction to vertically and closely support the cardboard. Adjustable feet 8 may be optionally provided below the support frame 11 to facilitate adjustment of the height and level of the conveyor line, adapting to the installation requirements of different workstations or subsequent mechanisms.

[0024] like Figure 1 and Figure 2 As shown, in order to improve the stability of the cardboard during the conveying process, symmetrically arranged baffles 7 are preferably provided on both sides of the synchronous belt conveyor 12. The baffles 7 can prevent the cardboard from tilting or shifting during the conveying process, and are particularly suitable for stable conveying of multiple cardboard sheets stacked together.

[0025] The guide rail 2 is a guide structure fixedly installed on one side of the synchronous belt conveyor assembly 1 and arranged along the length of the synchronous belt conveyor line 12. Its function is to restrict and guide the movement direction of the pusher device 3, and ensure that the pusher device 3 can accurately push the cardboard along the conveying path.

[0026] like Figure 3 and Figure 4 As shown, the feeding device 3 includes a fixed plate 31 and a moving component 32 disposed on the fixed plate 31. The moving component 32 preferably has a four-roller structure, with the rollers rolling in cooperation with the guide rail 2, allowing the fixed plate 31 to move smoothly along the guide rail 2. The feeding device 3 is mainly used to contact the tail end of the cardboard and, through the thrust provided by the drive structure 33, gradually feeds the cardboard to the next process.

[0027] like Figure 2 and Figure 3As shown, the drive structure 33 utilizes a spring-loaded mechanism to achieve its unpowered propulsion function. Specifically, one end of the structure is fixed to the fixed plate 31, and the other end is fixedly connected to the distal end of the fixed plate 31. The structure contains a spring-loaded mechanism, which uses the rewinding force of a measuring tape to achieve self-driven movement of the fixed plate 31. During use, the fixed plate 31 can be pulled to its initial position and then released, utilizing the elastic potential energy released by the spring-loaded mechanism to drive the fixed plate 31 forward slowly, achieving continuous and stable cardboard conveying and avoiding the vibration, noise, and energy consumption problems of traditional motor-driven systems.

[0028] To achieve precise positioning and blocking of the cardboard, a material-blocking assembly 34 is installed on the fixing plate 31. This assembly preferably includes a hollow sleeve 341, a vertical rod 342 rotatably disposed within the sleeve, and a baffle 343 fixed to the vertical rod 342. The baffle 343 is used to insert into the cardboard stack to form a stable position. A buffer pad 4 is preferably provided on the side of the baffle 343 facing the cardboard to buffer contact impact and protect the edges of the cardboard from scratches and deformation. A locking element 5 is installed on the outer surface of the hollow sleeve 341 to lock the angle of the vertical rod 342 after rotation, adapting to the shape and angle of the cardboard under different stacking conditions. For easy adjustment by the operator, a handle 6 is also provided on the sleeve to facilitate quick alignment of the baffle 343 with the cardboard stack.

[0029] Furthermore, in certain implementation scenarios, to further enhance the system's adaptability, guide rails 2 and pushing devices 3 can be symmetrically arranged on both sides of the synchronous belt conveyor 12, so that the pushing force is applied to the cardboard stack from both sides. This is particularly suitable for applications involving wide-width cardboard or cardboard with a large weight. Such structures can also be flexibly selected and configured according to process requirements.

[0030] By adopting the above-mentioned structural configuration, this utility model realizes the unpowered and automatic propulsion of cardboard. The overall structure is compact and reasonably arranged. In particular, with the coordinated cooperation of multiple mechanical modules, it not only ensures the stability and smoothness of the conveying process, but also improves the structure's adaptability to different cardboard sizes, thicknesses and stacking heights, effectively meeting the high-efficiency and high-stability feeding requirements of the case erector.

[0031] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
