Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, specifically a feeding device for a high-speed box opening machine for packaging boxes. Background Technology

[0002] In modern, high-efficiency packaging production lines, automated equipment plays a crucial role in the conveying, gripping, unfolding, forming, filling, and sealing of packaging boxes. Traditional packaging box equipment typically requires manual placement of large numbers of stacked boxes onto the feeding track. Due to the lack of stable clamping on the sides and bottom support, the stability between multiple stacked boxes is poor when conveying begins, easily leading to tipping or scattering. This not only interrupts the feeding process and affects production efficiency but can also damage the boxes, preventing subsequent processes from proceeding normally. For these reasons, workers cannot place large quantities of stacked boxes directly at once, limiting the amount of material that can be fed and hindering continuous, efficient, and continuous production. Utility Model Content

[0004] The purpose of this utility model is achieved by the following method: A feeding device for a high-speed box opening machine for packaging boxes, comprising a conveying mechanism and an unfolding mechanism mounted on a main frame. The conveying mechanism is used for the packaging box to enter the working range of the unfolding mechanism. The conveying mechanism includes conveyor belts symmetrically arranged on the main frame. Several guide platforms are installed on the outer circumference of the conveyor belts. The guide platforms on opposite sides form an installation groove for clamping the packaging box to be opened. The conveying mechanism also includes a bottom support belt installed between two conveyor belts and a push plate installed on the bottom support belt through a clamping structure. A drive motor drives the bottom support belt to drive the push plate to adhere to the packaging box and push the packaging box into the working range of the unfolding mechanism.

Spring columns installed on both sides of the pressure plate pass through the movable plate and are connected to the fixed plate. By controlling the drive handle, the movable plate is driven to press down toward the fixed plate end, clamping the bottom support belt in the clamping groove.

[0008] The spring column is fitted with a spring. One end of the spring presses against the lower end of the movable plate, and the other end presses against the upper end of the fixed plate.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings. A feeding device for a high-speed box opening machine for packaging boxes includes a conveying mechanism and an unfolding mechanism 2 mounted on a main frame 1. The conveying mechanism is used for the packaging box to enter the working range of the unfolding mechanism 2. The conveying mechanism includes conveyor belts 3 symmetrically arranged on the main frame 1. A plurality of guides 31 are installed on the outer circumference of the conveyor belts 3. The guides 31 arranged on opposite sides form an installation groove for clamping the packaging box to be opened. The conveying mechanism also includes a bottom support belt 4 installed between two conveyor belts 3, and a push plate 41 installed on the bottom support belt 4 through a clamping structure. A drive motor drives the bottom support belt 4 to drive the push plate 41 to fit against the packaging box and push the packaging box into the working range of the unfolding mechanism 2. Conveying sliders 51 are installed on both sides of the bottom support belt 4. A conveying slide rail 52 is connected to the lower end of the clamping structure. The conveying slide rail 52 is slidably connected to the conveying sliders 51.

[0020] The operator first stacks a large number of flattened packaging boxes in the conveyor mechanism. The conveyor mechanism includes a conveyor belt symmetrically arranged on the main frame, with guide rails on the outer circumference of the conveyor belt forming a mounting groove. The feeding packaging boxes are stacked in this groove, accommodating packaging boxes of different sizes and sizes for clamping and positioning. This provides stable constraint on both sides of the stack, effectively preventing the boxes from tipping over or scattering forward. This allows users to load large quantities of packaging boxes at once, significantly reducing the frequency of manual loading and improving the overall efficiency of the production line. At this point, the drive motor starts, driving the bottom support belt to rotate. The bottom support belt, through its clamping structure, pushes the push plate forward, adhering to the outer wall of the packaging box, thus propelling the box forward. Since the movement of the packaging box also synchronously drives the conveyor belt to rotate, it ensures that the packaging box is continuously clamped and constrained by the mounting groove during movement, while the bottom is actively pushed by the push plate. Under the dual action of clamping on both sides and pushing from the bottom, the entire stack of packaging boxes is stably conveyed into the working range of the unfolding mechanism, awaiting subsequent processes.

[0021] The conveyor belt 3 is a synchronous belt. Using synchronous belts as the conveyor belt, and symmetrically arranged on both sides of the main frame, ensures that the linear speed and position of the synchronous belts on both sides remain consistent, guaranteeing the stability and positional consistency of the packaging box during transport. This provides reliable positioning assurance for subsequent precise gripping and opening processes by the unfolding mechanism.

[0022] The clamping structure includes a mounting base 61 and a movable plate 62 connected to one side of the mounting base 61, and the push plate 41 is installed on the other side of the mounting base 61; the clamping structure also includes a fixed plate 63 connected to the conveying slide rail 52, and a clamping groove 7 is formed between the fixed plate 63 and the movable plate 62, and the bottom support belt 4 is installed in the clamping groove 7.

[0023] The clamping structure also includes a pressure plate 64 installed above the movable plate 62 and a drive handle 65 above it. Spring columns 8 installed on both sides of the pressure plate 64 pass through the movable plate 62 and are connected to the fixed plate 63. By controlling the drive handle 65, the movable plate 62 is driven to press down toward the fixed plate 63, clamping the bottom support belt 4 in the clamping groove 7.

[0024] The clamping structure includes a mounting base and a movable plate and a fixed plate connected to one side thereon. A push plate is connected to the other side of the mounting base as the movable end, while the conveyor rail is connected to the fixed plate as the fixed end. The bottom support belt is clamped in the groove formed by the fixed plate and the movable plate. When loading packaging boxes, the operator applies an upward force through the drive handle. The drive handle transmits this force to the pressure plate below, releasing the spring compression force. At this time, the movable plate automatically resets under the spring force, and the bottom support belt is released from clamping force. The operator then retracts the push plate to the feed port of the conveyor belt. Sufficient loading space is reserved between the push plate and the unfolding mechanism, allowing the operator to perform the loading operation. After loading is complete, the user applies pressure to the drive handle, causing the pressure plate to push the movable plate downwards towards the fixed plate, thus firmly clamping the bottom support belt. At this time, the drive motor starts, and the conveyor mechanism begins loading. Using the bottom support belt as the drive provides efficient and stable force transmission, and the clamping structure ensures that the push plate can reliably receive the driving force, preventing loosening. Unlocking and clamping are done using a drive handle, making the operation simple and quick.

[0025] The spring column 8 is fitted with a spring 81. One end of the spring 81 presses against the lower end of the movable plate 62, and the other end presses against the upper end of the fixed plate 63. The spring 81 generates a thrust, which always pushes the movable plate 62 away from the fixed plate 63 to reset.

[0026] When the operator releases the drive handle, the spring on the outer ring of the spring column releases its compressed elastic potential energy. The release of elastic potential energy generates a thrust that automatically pushes the movable plate against the fixed plate, thereby releasing the clamping state of the bottom support belt. This achieves one-button release, simplifies the replacement and maintenance of the bottom support belt, improves the ease of use and maintenance efficiency of the equipment, and ensures that the movable plate is in a fully open state when the bottom support belt is not clamped, avoiding potential damage to the equipment due to misoperation and effectively preventing accidents.

[0027] In summary: Firstly, through the cooperation of the conveyor belt and the guide table, the packaging box is placed in the mounting groove formed by the guide table on one side of the two conveyor belts. This applies a stable constraint force to both sides of the stack of packaging boxes, effectively preventing the packaging boxes from tilting to the sides or scattering forward. This allows users to load a large number of packaging boxes at once, significantly reducing the frequency of manual loading and improving the overall efficiency of the production line.

[0028] Subsequently, the user applies pressure to the drive handle of the clamping structure, causing the pressure plate to push the movable plate downwards towards the fixed plate, thus firmly clamping the bottom support belt in the groove formed between the movable and fixed plates. At this point, the drive motor starts, and the conveyor mechanism begins feeding. After the packaging boxes are completely fed, the operator applies an upward force through the drive handle. The drive handle transmits this pulling force to the pressure plate below, releasing the spring compression force. At this time, the movable plate automatically resets under the spring force, and the bottom support belt is released from clamping force. The operator then retracts the push plate to the feed port of the conveyor belt. At this point, sufficient feeding space is reserved between the push plate and the unfolding mechanism, allowing the operator to perform the feeding operation again.

[0029] With the coordinated operation of the clamping structure and the conveyor belt, the packaging box can be stably, quickly and accurately transported to the subsequent unfolding mechanism for unfolding, which improves the overall production efficiency of automated production. The conveying process is stable and controllable, so it can be widely used.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
