Description

Technical Field

[0001] This invention relates to the field of packaging box production technology, and in particular to an integrated machine for pressing and punching rigid packaging boxes. Background Technology

[0002] In the production of rigid packaging boxes, the combined application of punching and blister packaging technologies significantly enhances the functionality and aesthetics of the product. Punching creates necessary openings for ventilation, display, or carrying; while blister packaging adds cushioning and provides a unique tactile feel, ensuring structural strength while enabling customized patterns and functions, improving production efficiency, reducing costs, and meeting market demands for diverse and high-value-added packaging.

[0003] A search revealed a multi-axis linkage paper box bubble depressing machine according to patent authorization announcement number CN109551819B. The machine includes a bubble depressing box with conveyor supports on both sides, a conveyor belt between the top of the conveyor supports, a bubble depressing platform at the bottom inner side of the bubble depressing box, clamping heads at the four corners of the top of the bubble depressing platform, screws at each corner of the bubble depressing box, support sleeves on the upper part of the screws, and a lifting platform fixed at the four corners of the lifting platform. A hydraulic pump is located at the top of the lifting platform, and two sliding grooves are located at the bottom of the lifting platform. Support pulleys are fitted into the sliding grooves and fixed to the top of the slide block. Racks are fixed to the front and rear sides of the bottom of the lifting platform, and stroke gears are located below the racks. The stroke gears are fixed to the ends of the drive shaft and the follower shaft, respectively. A bubble depressing rod is also fixed to the bottom of the slide block, and a bubble depressing roller is rotatably connected to the bottom of the bubble depressing rod. This device achieves vertical downward and horizontal pushing through a specific structure to remove air bubbles and packing between the paper box and the protective film. However, although the bubble-pressing roller can squeeze and expel air, the raised portions of the protective film formed after the air bubbles are squeezed are prone to wrinkling during processing, affecting the appearance quality of the final product. Furthermore, for cardboard boxes requiring punching, this device cannot complete the punching operation simultaneously, necessitating additional punching equipment for subsequent processing. This not only increases the complexity of the production process but also raises the overall production cost. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides an integrated machine for pressing and punching rigid packaging boxes with good production effect.

[0005] The technical implementation scheme of the present invention is: a rigid packaging box foam pressing and punching integrated machine, comprising:

[0006] Base;

[0007] The frame is set on the top of the base. The top of the frame is equipped with a platform for placing packaging boxes and a positioning block located on the right side of the platform. A fitting groove for embedding the side of the packaging box is opened in the middle of the positioning block. A through groove is also opened on both sides of the positioning block. A set of drive shafts with a front-to-back spacing are rotatably arranged inside the positioning block on both sides. The end of one drive shaft on each side is connected to a small motor for driving the rotation. A sanding belt for removing punching burrs is also provided between the two drive shafts in the same group. The sides of the sanding belts on both sides extend through the inner wall of the fitting groove.

[0008] The bracket is set on the top rear side of the machine base. The top of the bracket is equipped with a cylinder with its telescopic end facing down. A pressure plate is connected to the telescopic end of the cylinder. An electric heating wire for ironing out wrinkles is also installed inside the pressure plate.

[0009] Cylinder 2 is located on the right side of the frame. The telescopic end of cylinder 2 is equipped with a perforated plate that can slide through the through slot for punching packaging boxes.

[0010] Optionally, it also includes a support frame. The support frame is provided on the left side of the machine base. A belt conveyor group driven by a motor on the same side is symmetrically arranged on the support frame. The motors on both sides are respectively installed on the side wall of the support frame to assist in the conveying of the packaging boxes to be processed. Limiting rings for limiting are provided on the belts of the belt conveyor group.

[0011] Optionally, it also includes an extension frame, which is provided on the left side of the frame and connected to the placement platform. The left end of the extension frame extends and is embedded between the two belt conveyor groups. An electric push rod with its telescopic end facing right is also installed on the extended part of the extension frame for pushing the dropped packaging box.

[0012] Optionally, it also includes a cylinder three, which is installed inside the machine base with its telescopic end facing upward. The telescopic end of the cylinder three passes through the top surface of the machine base, and a top plate for pushing material is connected to the telescopic end of the cylinder three. A cylinder four for pushing material forward is installed on the front side of the bracket.

[0013] Optionally, it also includes a second motor. The second motor with its output end facing forward is symmetrically mounted on the top of the base. A bidirectional lead screw is connected to the output end of the second motor. A limiting plate is threaded on the threads on both sides of the bidirectional lead screw. The bottom end of the limiting plate slides with the frame to limit the position of the packaging box.

[0014] Optionally, it also includes connecting rods, with connecting rods extending to the left connected to the limiting plates near the extension frame, and displacement plates connected to the connecting rods on the same side are slidably provided on both sides of the extension frame, so that the limiting plates and displacement plates can be adjusted in a coordinated manner.

[0015] Optionally, the limiting plate is inclined from bottom to top, consisting of a straight section and a bent section. The straight section provides a support surface for the packaging box to be inserted, while the bent section provides the necessary movement space for the packaging box to be unloaded.

[0016] Optionally, the front and rear side spacing of the top plate is wider than the width of the placement platform, so that the top plate completely covers and pushes the packaging box to move.

[0017] The present invention has the following advantages: 1. The present invention integrates the two major processes of blister pressing and punching into the same equipment through the combined design of the blister pressing plate and the punching plate. This not only simplifies the production process and reduces the number of required equipment, but also effectively reduces production costs and improves work efficiency.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0031] Example: A rigid packaging box foam pressing and punching integrated machine, such as... Figures 1-5 As shown, it includes:

[0032] Base 1 serves as the primary mounting platform;

[0033] The frame 2 is fixedly mounted on the top of the base 1. The top of the frame 2 has a placement platform 21 for placing the packaging box 100, and a positioning block 22 located on the right side of the placement platform 21. A fitting groove 221 is formed in the middle of the positioning block 22 to accommodate the punched side of the packaging box 100, thus fixing the position of the packaging box 100 during operation. The fitting groove 221 is a vertical groove. The positioning block 22 is divided into left and right parts, and a through groove 222 is formed on each of the left and right sides of the positioning block 22. A set of [unclear - possibly a type of slot] is also rotatably mounted inside each side of the positioning block 22. The drive shafts 24 are arranged in a front-to-back spacing. Each drive shaft 24 on one side is connected to a small motor 23 for driving rotation. A sanding belt 25 for removing punching burrs is also provided between the two drive shafts 24 in the same group. The sides of the sanding belts 25 on both sides pass through the inner wall of the fitting groove 221, which can be used to trim the edges of the packaging box 100 after punching. The burrs on the edge of the punched part are removed by the sanding belt 25, ensuring the smoothness of the edge, thereby optimizing the display effect of the packaging box 100 and improving the overall production quality.

[0034] A support 3 is located on the top rear side of the machine base 1. The top of the support 3 extends forward and is positioned directly above the placement table 21 for subsequent processing of the packaging box 100. A cylinder 31 with its telescopic end pointing downwards is installed on the top of the support 3. A bubble pressing plate 32 is connected to the telescopic end of the cylinder 31. Inside the bubble pressing plate 32, an electric heating wire 33 is installed to smooth out wrinkles. The cylinder 31 drives the connected bubble pressing plate 32 to move up and down, precisely controlling the downward pressure of the bubble pressing plate 32 on the packaging box 100 and effectively expelling air from inside the packaging box 100. Furthermore, by heating the bubble pressing plate 32 with the electric heating wire 33, wrinkles that may exist in the packaging box 100 can be smoothed out while performing the bubble pressing operation, thereby improving the overall quality and appearance of the product. This integrated processing method not only improves production efficiency but also ensures that the packaging box 100 achieves consistent and excellent processing standards.

[0035] Cylinder 2 4 is located on the right side of the frame 2. The telescopic end of cylinder 2 4 is provided with a perforated plate 41 that can slide through the through groove 222 for punching the packaging box 100.

[0036] Specifically, in conjunction with the above, this device innovatively adopts an integrated design for punching and bubbling operations, consolidating processes that traditionally required two separate machines into a single work platform. This simplifies the operation process, ensures the accuracy and consistency of processing steps, and significantly reduces the workload of operators. It not only improves the quality of the final product but also increases overall work efficiency. Furthermore, this device utilizes a heating wire 33 and a sanding belt 25 working in synergy to optimize the bubbling and punching processes, enhancing the device's versatility and flexibility, and ensuring high-quality standards in overall production.

[0037] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a support frame 5. The support frame 5 is located on the left side of the base 1. The support frame 5 is symmetrically arranged with belt conveyor groups 51 driven by motors 52 on the same side. The belt conveyor group 51 consists of drive rollers and conveyor belts. The motors 52 are connected to the drive rollers on the same side, and the motors 52 on both sides are fixedly installed on the left and right side walls of the support frame 5 to assist in the conveying of the packaging boxes 100 to be processed. Limiting rings 53 are provided on the belt of the belt conveyor group 51 to limit the conveying position of the packaging boxes 100. Thus, in combination with the above, the automation of the conveying of the packaging boxes 100 is realized through the coordinated work of the various components, integrating the originally independent operations into a continuous process. This improvement not only makes the conveying of the packaging boxes 100 more efficient and orderly, but also enhances the continuity of the operation of the entire device, thereby greatly improving production efficiency and quality control level.

[0038] like Figure 6 and Figure 7 As shown, it also includes an extension frame 54. An extension frame 54 is provided on the left side of the frame 2 and is connected to the placement table 21. The left end of the extension frame 54 extends and is embedded between the two belt conveyor groups 51. An electric push rod 55 with its telescopic end facing right is also installed on the extended part of the extension frame 54 for pushing the packaging box 100 to fall. When the packaging box 100 completes the current conveying, the extension frame 54 and the electric push rod 55 work together to ensure that the packaging box 100 can smoothly and continuously enter the next processing stage, thereby improving the speed and efficiency of the overall production line.

[0039] like Figure 8 As shown, it also includes cylinder 3 6. Cylinder 3 6 with its telescopic end facing upward is installed inside the base 1. The telescopic end of cylinder 3 6 passes through the top surface of the base 1, and a top plate 61 for pushing material is connected to the telescopic end of cylinder 3 6. The distance between the front and rear sides of the top plate 61 is wider than the width of the placement table 21, so that the top plate 61 completely covers and pushes the packaging box 100 to move. Cylinder 4 62 for pushing material forward is installed on the front side of the bracket 3. Through the coordinated cooperation of the above components, the packaging box 100 is quickly discharged after processing through an upward and forward pushing action, making the operation more continuous and thus improving the overall work efficiency.

[0040] like Figure 9As shown, it also includes a second motor 7. The second motor 7 with its output end facing forward is symmetrically installed on the top of the base 1. A double-acting lead screw 71 is connected to the output end of the second motor 7. A limiting plate 72 is threaded on the threads on both sides of the double-acting lead screw 71. The bottom end of the limiting plate 72 is slidably engaged with the frame 2 to limit the placement position of the packaging box 100. The limiting plate 72 is inclined from bottom to top, consisting of a straight section and a bent section. The straight section can provide a stable support surface for the packaging box 100 to be embedded and placed, while the bent section reserves the necessary movement space for the packaging box 100 to be discharged, avoiding possible obstruction during the subsequent discharge process and ensuring the smooth progress of subsequent operations.

[0041] like Figure 9 As shown, it also includes a connecting rod 73. The two limiting plates 72 near the extension frame 54 are each connected to a connecting rod 73 extending to the left. On the front and rear sides of the extension frame 54, displacement plates 74 connected to the connecting rods 73 on the same side are also slidably provided, so that the limiting plates 72 and displacement plates 74 can be adjusted in coordination to adjust the distance between the front and rear sides of the extension frame 54. This allows for controllable placement space of the packaging box 100. The distance between the front and rear sides of the extension frame 54 can be quickly adjusted according to the needs of different packaging boxes 100, adapting to various production tasks and effectively improving the overall adaptability and flexibility of the device.

[0042] In use, the device is first adjusted according to the specifications of the packaging box 100 of this batch. The motor 7 is started, which drives the corresponding bidirectional lead screw 71 to rotate, so that its upper limit plate 72 moves and adjusts along the thread trend. Then the distance between each set of limit plates 72 changes, ensuring that the front and rear distance of the limit plate 72 can be adapted to the placement of the packaging box 100. At the same time, as the limit plate 72 moves, it will drive the connected connecting rod 73 and displacement plate 74 to move synchronously. Then the displacement plates 74 on both sides slide on both sides of the extension frame 54, thereby synchronously adjusting the feeding width of the extension frame 54. Then the production operation process of the packaging box 100 can be started.

[0043] The operator starts motor 52, driving the corresponding belt conveyor group 51 to operate. The operator then places the packaging box 100 to be processed onto the two belt conveyor groups 51. The packaging box 100 is restrained by the retaining ring 53 and transported from left to right between the belt conveyor groups 51. When the packaging box 100 reaches its end, it falls onto the extension frame 54 under gravity. Then, the electric push rod 55 is activated, extending its telescopic end and pushing the packaging box 100 to the right. The packaging box 100 then moves onto the placement table 21. The operator then places the right side of the packaging box 100... The packaging box 100 is placed on the placement platform 21 by fitting into the groove 221 of the positioning block 22, with its bottom end positioned between the limiting plates 72. After the position of the packaging box 100 is confirmed, cylinders 31 and 4 are activated simultaneously. The telescopic end of cylinder 31 gradually extends and drives the bubble pressing plate 32 connected to it to move downward. The bubble pressing plate 32 performs bubble pressing on the packaging box 100. When the bubble pressing plate 32 contacts the packaging box 100, the heating wire 33 inside the bubble pressing plate 32 is energized and heated, so that when the bubble pressing plate 32 contacts the surface of the packaging box 100, it can not only apply pressure but also... The force removes air and also helps to smooth out wrinkles through heat, ensuring the flatness of the packaging box 100 surface. During this process, the telescopic end of cylinder two 4 also extends and drives the connected perforated plate 41 to move to the left, so that the perforated plate 41 passes through the through groove 222 of the positioning block 22, thereby punching the side of the packaging box 100. After the packaging box 100 is compressed and punched, cylinder three 6 can be activated to push the connected top plate 61 upward, thereby lifting the packaging box 100 placed on it. During the upward movement of the packaging box 100, the small motor 23... The synchronous drive drives the connected drive shaft 24 to rotate, thereby driving the corresponding abrasive belt 25 to smooth the burrs at the punched area of ​​the packaging box 100, ensuring the smoothness of the edges at the punched area, making the punched area flatter and presenting a better display effect. When the packaging box 100 is removed from the placement table 21, that is, when the packaging box 100 is moved to a certain height, the cylinder 62 starts synchronously and pushes the moved packaging box 100 forward, so that the distance between the packaging box 100 and the operator is closer, so as to pick it up. Then the processed packaging boxes 100 can be placed together.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
