Description

Technical Field

[0001] This utility model relates to the field of automatic box folding machine technology, specifically to a feeding component for an automatic box folding machine. Background Technology

[0002] In automated production within the packaging industry, automatic carton folding machines are key equipment for achieving mass production of cardboard boxes, widely used in food, pharmaceuticals, daily necessities, cosmetics, and other fields. The feeding assembly, as the core module of the folding machine, is responsible for sequentially and accurately conveying the paper sheets to be folded to the folding station; its performance directly determines folding efficiency and product quality.

[0003] However, existing automatic box folding machine feeding components have significant drawbacks: Poor size compatibility: Most feeding components only adapt to a single or a few fixed-size paper sheets. When production needs change (such as changing to different product packaging specifications), manual disassembly and adjustment of side baffles, positioning blocks, and other structures are required, which is cumbersome and time-consuming. For example, when a food company changed its box specifications, adjusting the feeding components alone required a shutdown of more than 30 minutes, severely restricting production continuity. Low precision of manual adjustment: Manual adjustment of the side baffle position is prone to deviation, causing the paper sheets to shift or skew during feeding, which in turn affects the subsequent box folding accuracy, with a defect rate of over 5%, increasing enterprise costs. High equipment investment costs: To adapt to multiple sizes, enterprises need to configure multiple sets of feeding equipment or frequently replace parts, increasing the burden of equipment purchase and inventory management.

[0004] In summary, the "non-adaptive" defects of existing feeding components can no longer meet the packaging industry's demand for efficient, flexible, and precise production, and there is an urgent need for a feeding solution that can automatically accommodate paper sheets of different sizes. Utility Model Content

[0005] The present invention aims to overcome at least one of the defects of the prior art and provide an automatic box folding machine feeding component to achieve adaptive adjustment for material size.

[0006] Specifically, the basic structure of the automatic box-folding machine feeding assembly protected by this utility model includes a base, a feeding and conveying mechanism, and an adjusting mechanism. The feeding and conveying mechanism, mounted on the base, can be composed of a conveyor belt and a drive device, and is responsible for material conveying. The adjusting mechanism includes a first drive assembly, a first side baffle assembly, a second drive assembly, and a second side baffle assembly. The two side baffle assemblies are respectively located on both sides of the feeding and conveying mechanism, and the two drive assemblies are located below the base. The width positioning of the material in the feeding direction is achieved by driving the side baffle assemblies to move horizontally. This structure, by placing the drive assemblies below the base, avoids interference with the upper feeding space, saving overall equipment space. The independent side baffle assemblies on both sides, in conjunction with the drive assemblies, can flexibly adjust the spacing to adapt to materials of different widths, solving the problem of poor adaptability of traditional feeding assemblies and improving the versatility of the equipment.

[0007] Furthermore, the first drive assembly sequentially drives the first driving gear, the first chain, the first driven gear, and the first lead screw assembly via the first motor, while simultaneously driving the second lead screw assembly via the second driven gear, the second chain, and the third driven gear, thus causing the two ends of the first side baffle assembly to move synchronously. The second drive assembly employs a similar transmission logic, driving the third and fourth lead screw assemblies via the second motor to achieve synchronous movement of the two ends of the second side baffle assembly. This multi-stage transmission structure of motor, gears, chain, and lead screw ensures uniform force and synchronous movement at both ends of the side baffle assembly, avoiding tilting of the side baffle caused by unilateral movement and improving the accuracy of width adjustment. Simultaneously, the chain drive features a stable transmission ratio and high load-bearing capacity, making it suitable for long-term, high-frequency adjustment operations and extending the equipment's service life.

[0008] Furthermore, both the first and second lead screw assemblies include a lead screw component, a fixing component, and bearings. The lead screw component is connected to the side baffle assembly via bearings and fixed to the base via fixing components, ensuring stable rotation and a fixed axial position of the lead screw component. The bearings reduce friction between the lead screw component and the side baffle assembly, making rotation smoother and reducing energy consumption during adjustment. The fixing components firmly mount the lead screw assembly to the base, preventing lead screw wobbling during adjustment, ensuring the straightness of the side baffle assembly's movement, and further improving the accuracy of width positioning. The fixed-end structure enhances the rigidity of the lead screw assembly, enabling it to withstand larger lateral forces and adapt to the blocking requirements of materials of different thicknesses.

[0009] Furthermore, the structures of the third and fourth lead screw assemblies are similar to those described above, both connecting to the second side baffle assembly and the base via lead screw components, fixing components, and bearings. In this structure, the lead screw component is connected to the second side baffle assembly via bearings, ensuring flexible rotation, while the fixing components stably mount the lead screw assembly on the base, preventing displacement. The beneficial effects are that the symmetrical lead screw assembly design allows for more synchronized movement at both ends of the second side baffle assembly, creating a uniform width gap when working with the first side baffle assembly, preventing material deviation during conveying due to uneven spacing on both sides. In addition, the combination of bearings and fixing components reduces component wear and extends the maintenance cycle of the lead screw assembly.

[0010] Furthermore, this utility model defines the composition of the first side baffle assembly and the second side baffle assembly, both of which include a baffle, a fixing bolt, an adjusting rod, and a fixing plate. The baffle is connected to the adjusting rod via the fixing bolt, and the other end of the adjusting rod is connected to the fixing plate. The drive assembly is connected to the fixing plate. The baffle directly contacts the material and serves a positioning function; the adjusting rod can be finely adjusted in length via the fixing bolt to adapt to different installation requirements; the fixing plate, as a carrier connecting the drive assembly, transmits the driving force to the entire side baffle assembly. This modular structure facilitates the individual disassembly and replacement of each component, reducing maintenance costs; the fine-tuning function of the adjusting rod allows the position of the baffle to be precisely adjusted according to the actual material size, improving positioning flexibility; the fixing plate enhances the overall rigidity of the side baffle assembly, preventing baffle deformation during the driving process.

[0011] Furthermore, this utility model also includes a first support rod and a second support rod, which are arranged in parallel and rotatably connected at both ends to the first and second fixing plates, respectively. The first and second support rods connect the first side baffle assembly and the second side baffle assembly into a whole, forming a stable parallelogram structure. Its advantages lie in enhancing the structural stability between the two side baffle assemblies, preventing deformation caused by uneven force when adjusting the width or blocking materials; the parallel support rods ensure that the two side baffle assemblies always remain parallel, avoiding tilting during spacing adjustment, ensuring the symmetry of material positioning on both sides, and further improving feeding accuracy.

[0012] This invention further incorporates a chain support gear, located below and meshing with the second chain. The chain support gear supports the chain, preventing it from sagging due to its own weight or tension during transmission. This avoids interference with other components caused by chain sagging, ensuring smooth transmission. Simultaneously, it reduces misalignment during chain-gear meshing, lowers tooth surface wear, and extends the service life of both the chain and gear. Stable chain transmission ensures accurate power transmission in the first drive assembly, preventing the adjustment precision of the side baffle assembly from being affected by transmission deviations.

[0013] Furthermore, the feeding and conveying mechanism includes a third drive assembly, a drive roller, a conveyor belt, and a driven roller. The third drive assembly is fixed to one side of the base, while the drive roller and driven roller are respectively located at both ends of the base, connected by the conveyor belt. The drive roller rotates under the drive of the third drive assembly, driving the conveyor belt through friction. The driven roller rotates with the conveyor belt and provides support. This structural layout is reasonable, placing the drive assembly on one side of the base to avoid occupying feeding space; the cooperation between the drive roller and the driven roller ensures appropriate tension on the conveyor belt, ensuring smooth material conveying and reducing slippage or jamming; the continuous operation of the conveyor belt enables automated material feeding, improving production efficiency.

[0014] Furthermore, the third drive assembly includes a third motor, a third drive gear, a fifth chain, and a seventh driven gear, with the seventh driven gear connected to one end of the drive roller. The third motor drives the drive roller to rotate via gear and chain transmission, thereby driving the conveyor belt. The gear and chain transmission method has high transmission efficiency and stability, ensuring uniform rotational speed of the drive roller and stable conveyor belt speed, preventing material displacement due to speed fluctuations. Simultaneously, this transmission structure facilitates adjustment of the transmission ratio, allowing for adjustment of the conveyor belt speed according to the feeding requirements of different materials, thus improving the adaptability of the equipment.

[0015] Furthermore, the angle between the axis of the fifth chain and the horizontal plane in this invention is 30° to 60°. This angle setting allows the chain transmission path of the third drive component to better fit the overall structure of the equipment, avoiding interference with the adjustment mechanism below the base or the feeding space above. It makes efficient use of the internal space of the equipment, resulting in a more compact overall structure; simultaneously, the chain's stress state is optimized within this angle range, reducing chain slack or over-tension, ensuring transmission stability and reliability, and extending the chain's service life.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention achieves precise adjustment and stable conveying of material width through a rational layout of the base, feeding and conveying mechanism, and adjustment mechanism. It employs a multi-stage transmission drive assembly, a symmetrical lead screw structure, and modular side baffle assemblies. Its compact structure saves space; its stable transmission and high adjustment accuracy allow it to adapt to materials of different widths, improving the equipment's versatility. The design of each component enhances structural rigidity and wear resistance, extending service life and reducing maintenance costs. The automated feeding and adjustment process reduces manual intervention, improving production efficiency and feeding stability, making it suitable for various automatic folding box machine feeding scenarios.
