Description

Technical Field

[0001] This invention relates to the field of cardboard box stamping technology, and in particular to a high-efficiency stamping mold for corrugated cardboard boxes and its stamping method. Background Technology

[0002] Corrugated cardboard boxes are widely used in various industries such as food, electronics, home appliances, and logistics due to their advantages such as lightweight, high strength, excellent cushioning performance, and recyclability. As a packaging and protective carrier for products, their market demand continues to rise. In the production and processing of corrugated cardboard boxes, stamping is one of the core processes. This process directly determines the dimensional accuracy, forming quality, and production efficiency of the cardboard box. As a key piece of equipment for realizing this process, the structural rationality and functional applicability of the stamping mold have an important impact on the entire cardboard box production chain. Currently, most corrugated cardboard box stamping molds on the market have a fixed structure design, which can only be used to stamp and form corrugated cardboard boxes of a single size. With the diversification of market demand, downstream industries have increasingly diverse requirements for the size and specifications of corrugated cardboard boxes. To meet the production needs of different sized cardboard boxes, corresponding stamping molds need to be changed. This not only leads to a significant increase in production costs, but also increases the workload of workers, which is time-consuming and labor-intensive. It is impossible to quickly respond to the flexible order demands of the market, which seriously restricts the improvement of production efficiency.

[0003] Therefore, it is necessary to provide a new high-efficiency stamping die for corrugated cardboard boxes to solve the above-mentioned technical problems. Summary of the Invention

Finally, cylinder two is started, which drives the top plate to move and push the end bottom plate of the cardboard to fit with the end side plate. S5: The hydraulic mechanism resets, causing the L-shaped pressure plate to move upward, the spring releases its elastic force, and pushes the support plate and the formed carton to the initial position.

[0015] Compared with related technologies, the high-efficiency stamping die for corrugated cardboard boxes provided by this invention has the following advantages: The design of the drive and adjustment components enables flexible adaptation to cardboard boxes of different sizes.

The adjustment component is linked with the rack and pinion transmission mechanism to simultaneously calibrate the positions of the side baffles, push plates, and top plates, adapting to the width and length of the cardboard box. This eliminates the need for separate design and customization of molds for different cardboard box sizes, effectively reducing mold design, manufacturing, and storage costs. It also avoids the tedious operation of frequent mold changes, lowering equipment investment and production maintenance costs. During the size adjustment stage, the screw driven by the motor and the gear rack transmission eliminate the need for manual adjustment of each positioning component, ensuring precise and rapid adjustment and significantly shortening production preparation time. In the stamping stage, the hydraulic mechanism drives the L-shaped pressure plate for efficient stamping, while the spring buffer structure ensures stamping stability. In the auxiliary forming stage, the cylinder drives the push plate and top plate in conjunction with the gluing mechanism to complete the side panel folding, gluing, and bonding processes in one integrated manner, eliminating the need for subsequent manual secondary processing. The entire operation process is seamless, and the automated operation not only reduces manual intervention and the labor intensity of workers but also significantly increases the production capacity per unit time, enabling efficient and continuous production of multi-specification cartons.

[0029] A stamping method for a high-efficiency stamping die for corrugated cardboard boxes, the stamping method comprising the following steps: S1: Adjust the position of the L-shaped pressure plate 6 according to the size of the carton board to be punched. Specifically, drive the bidirectional screw 9 through motor 12 to move the corresponding L-shaped pressure plate 6 laterally, and then drive the bidirectional screw 16 through motor 21 to move the corresponding L-shaped pressure plate 6 longitudinally. When the adjustment is suitable for the size of the carton board to be punched, turn off motor 12 and motor 21. S2: Adjust the position of the side baffle 8. Specifically, the side baffle 8 is moved by the double screw 24 driven by the motor 3 23, which in turn moves the corresponding push plate 29 to adapt to the width of the carton to be punched. S3: The electric push rod 32 drives the rack 31 to move, which in turn drives the top plate 34 to move, and at the same time drives the push plate 29 to move, adapting to the length of the cardboard to be punched. S4: Place the cardboard to be stamped on the support plate 7, start the hydraulic mechanism 3, and drive the L-shaped pressure plate 6 to move downward through the connecting seat 4 to stamp the cardboard. At the same time, drive the support plate 7 to move downward and compress the spring 38. Then, cylinder 28 is started, which drives the push plate 29 to move and fold the end side plate of the cardboard. Then, the glue dispensing mechanism 36 is started to apply glue to the end bottom plate of the cardboard. Finally, cylinder 33 is started, which drives the top plate 34 to move and push the end bottom plate of the cardboard to fit with the end side plate. S5: The hydraulic mechanism 3 resets, causing the L-shaped pressure plate 6 to move upward, and the spring 38 releases its elastic force, pushing the support plate 7 and the formed carton to the initial position.

[0030] The working principle of the high-efficiency stamping mold for corrugated cardboard boxes provided by this invention is as follows: As the core execution component of the stamping process, the L-shaped pressure plate 6 achieves horizontal and vertical position adjustment through two sets of mutually perpendicular drive mechanisms to adapt to the stamping requirements of different sized carton boards. During horizontal adjustment, the motor 12 is started, and its output end drives the drive gear 15 to rotate. Since the drive gear 15 meshes with the driven gear 14 in the middle of the bidirectional screw 9, it drives the bidirectional screw 9 to rotate on the top of the connecting seat 4. The slider 10, which is symmetrically threaded on the outer wall of the bidirectional screw 9, moves in opposite directions along the bidirectional screw 9 due to the opposite direction of the thread rotation. The slider 10 drives the slide rod 11 to move synchronously through the connecting rod 13 fixed at the bottom. The two ends of the slide rod 11 are embedded in the groove at one end of the L-shaped pressure plate 6 and slide in cooperation with the groove wall. Finally, it pushes the two sets of diagonally arranged L-shaped pressure plates 6 to increase the horizontal spacing and complete the adaptation of the carton's horizontal size. During longitudinal adjustment, motor 21 is started, and its output drives the active bevel gear 22 to rotate. The active bevel gear 22 meshes with the driven bevel gear 20 in the middle of the bidirectional screw 16, driving the bidirectional screw 16 to rotate. The slider 17 on the bidirectional screw 16 rotates accordingly and moves in opposite directions. Through the connecting rod 18, it drives the sliding rod 19 to move. The sliding rod 19 is embedded in the groove at the other end of the L-shaped pressure plate 6, driving the L-shaped pressure plate 6 to adjust the longitudinal spacing. Through independent adjustment of the transverse and longitudinal directions, the size of the stamping area enclosed by the L-shaped pressure plate 6 can be flexibly adjusted to adapt to cardboard boards of different lengths and widths. Side baffles 8 are used to limit the width of the carton board, and their position adjustment is driven by the adjustment component. The motor 23 is started, and its output end drives the bidirectional screw 24 to rotate at the bottom of the base 1. The slider 25 connected to the symmetrical thread on the outer wall of the bidirectional screw 24 rotates and moves in opposite directions. The mating rod at the top of the slider 25 passes through the mating groove inside the base 1 and is fixedly connected to the side baffles 8, thereby driving the side baffles 8 on both sides to move along both sides of the bearing plate 7, realizing the adjustment of the spacing between the side baffles 8 to match the width of the carton board. At the same time, the support rod 26 fixed at the top of the mating rod moves synchronously with the side baffles 8. The mounting block 27 slidably connected to the outer wall of the support rod 26 and the cylinder 28 and push plate 29 on the mounting block 27 also adjust their positions synchronously in the width direction with the side baffles 8 to ensure that the push plate 29 corresponds to the end position of the carton board. To accommodate the length of the cardboard box, the position of the top plate 34 is adjusted via a rack and pinion gear transmission mechanism 31, simultaneously coordinating with the push plate 29 to achieve length-direction positioning. The electric push rod 32 is activated, its output end pushing a connected rack 31 to move along the top of the mounting plate 5. This rack 31 meshes with a rotating gear 30 at the center of the mounting plate 5, driving the rotating gear 30 to rotate. Simultaneously, the rotating gear 30 meshes with another symmetrically arranged rack 31, causing the two racks 31 to move in opposite directions. The end of the rack 31 furthest from the rotating gear 30 is fixedly connected to a... The placement plate moves with the rack 31, which drives the top cylinder 33 and the top plate 34 connected to the output end of the cylinder 33 to move synchronously, thereby adjusting the spacing of the top plate 34 to match the length of the carton board. At the same time, the connecting rod 35 fixed to the side wall of the placement plate is embedded in the mounting block 27 and slides with the mounting block 27, which drives the mounting block 27 to slide along the support rod 26. The cylinder 28 fixed inside the mounting block 27 moves accordingly, completing the position calibration of the push plate 29 in the length direction, ensuring that the push plate 29 and the end side plate of the carton board are accurately aligned. After all dimensional adjustments are completed, the corrugated cardboard box to be stamped is placed stably on the support plate 7. Then, the hydraulic mechanism 3 is started to carry out the stamping operation. After the hydraulic mechanism 3 is started, its output end pushes the connecting seat 4 and the adjusted L-shaped pressure plate 6 to move downward. The L-shaped pressure plate 6 contacts the surface of the cardboard box and applies downward stamping force, causing the cardboard box and the support plate 7 to move downward synchronously. The bottom of the support plate 7 is slidably connected to the base 1 through the guide rod 37. The spring 38 sleeved on the outer wall of the guide rod 37 is compressed as the support plate 7 moves downward. The elastic reaction force generated by the spring 38 can buffer the stamping impact force, avoid damage to the cardboard box due to uneven stamping force, and ensure the stability of the stamping process. Under the continuous stamping action of the L-shaped pressure plate 6, after the bottom of the cardboard box contacts the side baffle 8, it is initially formed along the preset folds, forming the basic outline of the cardboard box. After stamping, the push plate 29 and top plate 34 are driven by a cylinder to cooperate with the glue dispensing mechanism 36 to complete the folding of the carton side panels, glue dispensing, and bonding of the bottom plate with the side panels, achieving integrated molding of the carton without the need for subsequent manual processing. Specifically, the cylinder 28 is activated, and its output end pushes the push plate 29 to move towards the end of the carton board, folding the side panels at both ends of the carton board inward along the creases, so that the side panels are perpendicular to the bottom plate. Subsequently, the glue dispensing mechanism 36, which is symmetrically arranged on the top of the base 1, is activated, and the glue dispensing mechanism 36 dispenses glue towards the end of the carton board. Precise glue is applied to the preset bonding position of the bottom plate to ensure adhesion between the bottom plate and the side plate. After glue application, cylinder 2 33 is activated, and its output end pushes the top plate 34 to move towards the end of the carton board. The top plate 34 applies a thrust to push the bottom plate at the end of the carton board towards the side plate, so that the bottom plate and the side plate are precisely bonded. At the same time, cylinder 1 28 retracts, driving the push plate 29 to reset. The adhesiveness of the glue is used to fix the bottom plate and the side plate, completing the overall forming of the carton. Then cylinder 2 33 resets, driving the top plate 34 to reset. After the carton is formed, the hydraulic mechanism 3 stops outputting power and resets upward, driving the connecting seat 4 and the L-shaped pressure plate 6 to move upward synchronously, relieving the pressure on the formed carton. At this time, the compressed spring 38 releases its elastic potential energy, pushing the support plate 7 upward along the guide rod 37 until the support plate 7 returns to its initial position, while simultaneously lifting the formed carton to a height that is easy to pick up. The operator can directly remove the formed carton from the support plate 7 to complete a single stamping operation. If continuous production is required, the above process of size adjustment, positioning, stamping, forming, and reset can be repeated to achieve efficient continuous production of cartons of various specifications.
