DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0031] Embodiment: A rigid packaging box foaming and punching integrated machine, such as Figure 1-Figure 5 As shown, including:

[0032] Base 1 is the main installation carrier;

[0033] The frame 2 is fixedly arranged on the top of the base 1. A placement table 21 for placing the packaging box 100 and a positioning block 22 located on the right side of the placement table 21 are arranged on the top of the frame 2. An engaging groove 221 for embedding the punched side of the packaging box 100 is opened in the middle of the positioning block 22, so that the position of the packaging box 100 is fixed during operation, and the engaging groove 221 is an up-and-down groove. The positioning block 22 is divided into left and right parts, and a through groove 222 is opened on the left and right sides of the positioning block 22, respectively. A set of through grooves 222 are also rotatably arranged inside the two sides of the positioning block 22. The drive shafts 24 are arranged at intervals in front and back, and the end of one of the drive shafts 24 on each side is connected to a small motor 23 for driving the rotation. A frosting belt 25 for removing punching burrs is also arranged between the two drive shafts 24 in the same group. The side edges of the frosting belts 25 on both sides are passed through the inner wall of the fitting groove 221, which can be used to trim the packaging box 100 after the subsequent punching is completed, so that the edge burrs of the punching part are removed by the frosting belt 25, ensuring the smoothness of the edge, thereby optimizing the display effect of the packaging box 100, thereby improving the overall production quality;

[0034] The bracket 3 is arranged at the top rear side of the base 1. The top of the bracket 3 extends forward and is placed directly above the placement table 21, so as to facilitate the subsequent processing of the packaging box 100. The top of the bracket 3 is provided with a cylinder 31 with a telescopic end facing downward. A bubble pressing plate 32 is connected to the telescopic end of the cylinder 31. A heating wire 33 for ironing out wrinkles is also arranged inside the bubble pressing plate 32. The cylinder 31 is used to drive the connected bubble pressing plate 32 to move up and down, so as to accurately control the downward pressure of the bubble pressing plate 32 on the packaging box 100, and effectively discharge the air in the packaging box 100. On this basis, the bubble pressing plate 32 is heated by the heating wire 33, and while performing the bubble pressing operation, the wrinkles that may exist in the packaging box 100 can also be ironed out, 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 can meet consistent and excellent processing standards;

[0035] The cylinder 2 4 is arranged on the right side of the frame 2 , and a punching plate 41 capable of sliding through the through slot 222 is arranged on the telescopic end of the cylinder 2 4 for punching the packaging box 100 .

[0036] Specifically, in combination with the above, the device innovatively adopts an integrated design of punching and bubble pressing operations, integrating the processes that traditionally require two independent devices to complete onto one operating platform, so as to simplify the operation process, ensure the accuracy and consistency of the processing steps, and significantly reduce the workload of operators, which can not only improve the quality of the final product, but also improve the overall work efficiency. In addition, the device also uses the electric heating wire 33 and the frosting belt 25 to cooperate with each other to optimize the bubble pressing and punching process, enhance the versatility and flexibility of the device, and ensure the high quality standards of the overall production.

[0037] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a load-bearing frame 5. The load-bearing frame 5 is arranged on the left side of the machine base 1. The load-bearing frame 5 is symmetrically arranged with a belt transmission group 51 driven by a motor 52 on the same side. The belt transmission group 51 is composed of a driving roller and a conveying belt. The motor 52 is respectively connected to the driving roller on the same side, and the motors 52 on both sides are respectively fixedly installed on the left and right side walls of the load-bearing frame 5 to assist in the conveying of the packaging box 100 to be processed, and a limiting ring 53 for limiting the conveying position of the packaging box 100 is arranged on the belt of the belt transmission group 51. From now on, combined with the above, through the coordinated work of various components, the automation of the conveying of the packaging box 100 is realized, and the originally independent operations are integrated into a coherent process. This improvement not only makes the transmission of the packaging box 100 more efficient and orderly, but also enhances the continuity of the operation of the entire device, thereby greatly improving the production efficiency and quality control level.

[0038] like Figure 6 and Figure 7 As shown, it also includes an extension frame 54. The left side of the frame 2 is provided with an extension frame 54 connected with the placement table 21, and the left end of the extension frame 54 extends and is embedded between the belt conveyor groups 51 on both sides. An electric push rod 55 with a telescopic end facing right is also installed on the extended part of the extension frame 54, which is used to push the dropped packaging box 100. When the packaging box 100 completes the current transportation, the extension frame 54 and the electric push rod 55 are connected and cooperated to ensure that the packaging box 100 can smoothly and uninterruptedly enter the next processing stage, thereby improving the speed and efficiency of the entire production line.

[0039] like Figure 8 As shown, it also includes a cylinder three 6. A cylinder three 6 with a telescopic end facing upward is installed inside the machine base 1. The telescopic end of the cylinder three 6 passes through the top surface of the machine base 1, and a top plate 61 for pushing materials is also connected to the telescopic end of the cylinder three 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 can completely cover and push the packaging box 100 to move. A cylinder four 62 for pushing materials forward is installed on the front side of the bracket 3. Through the coordinated cooperation of the above-mentioned components, through a push-up and push-forward action, the packaging box 100 can be quickly discharged after processing, so that the operation is more consistent, thereby improving the overall operating efficiency.

[0040] like Fig. 9As shown, it also includes a motor 2 7. The motor 2 7 with the output end facing forward is symmetrically installed on the top of the base 1. A bidirectional screw rod 71 is respectively connected to the output end of the motor 2 7. A limit plate 72 is respectively threadedly arranged on the threads on both sides of the bidirectional screw rod 71. The bottom ends of the limit plates 72 are slidably matched with the frame 2 to limit the position where the packaging box 100 is placed. The limit plates 72 are inclined from the bottom to the top and are composed of a straight section and a bent section. The straight section can provide a stable supporting surface for the packaging box 100 to be embedded and placed, and the bent section reserves necessary moving space for the unloading operation of the packaging box 100, thereby avoiding possible obstacles in the subsequent unloading process and ensuring the smooth progress of subsequent operations.

[0041] like Fig. 9 As shown, it also includes a connecting rod 73. The two limit plates 72 close to the extension frame 54 are connected with a connecting rod 73 extending to the left. Displacement plates 74 connected to the connecting rod 73 on the same side are also slidably arranged on the front and rear sides of the extension frame 54, so that the limit plates 72 and the displacement plates 74 can be coordinated to adjust their positions, thereby adjusting the distance between the front and rear sides of the extension frame 54, thereby realizing the controllability of the space for placing the packaging box 100. According to the needs of different packaging boxes 100, the distance between the front and rear sides of the extension frame 54 can be quickly adjusted to adapt to various production tasks, thereby effectively improving the overall adaptability and flexibility of the device.

[0042] When in use, firstly, the device is adjusted according to the specifications of the batch of packaging boxes 100, and the motor 2 7 is started, thereby driving the corresponding bidirectional screw rod 71 to rotate, so that its upper limit plate 72 is moved and adjusted along the thread trend, and then the spacing between each group of limit plates 72 changes, ensuring that the front and rear spacing of the limit plates 72 can adapt to the placement of the packaging box 100. At the same time, as the limit plates 72 move, the connected connecting rods 73 and displacement plates 74 are synchronously driven to move, and 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, and then the production operation process of the packaging box 100 can be started;

[0043] The motor 1 52 is started to drive the corresponding belt conveyor group 51 to operate, and then the operator places the packaging box 100 to be processed on the belt conveyor groups 51 on both sides. The packaging box 100 is restricted by the limiting ring 53 and conveyed from left to right between the belt conveyor groups 51. When the packaging box 100 moves to the end, it falls to the extension frame 54 under the action of gravity, and then the electric push rod 55 is started to extend its telescopic end and push the packaging box 100 to move to the right. Then the packaging box 100 moves to the placement table 21, and the operator places the right side of the packaging box 100. The packaging box 100 is embedded in the fitting groove 221 of the positioning block 22, so that the packaging box 100 is placed on the placement table 21, and the bottom end is placed between the limiting plates 72. After the position of the packaging box 100 is confirmed, the cylinder 1 31 and the cylinder 2 4 can be started synchronously. The telescopic end of the cylinder 1 31 gradually extends and drives the bubble pressing plate 32 connected thereto 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 electric heating wire 33 in 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 air can be removed by force and the existing wrinkles can be ironed out by heat to ensure the flatness of the surface of the packaging box 100. In this process, the telescopic end of the cylinder 2 4 is also driven to extend and drive the connected punching plate 41 to move left, so that the punching plate 41 passes through the through slot 222 of the positioning block 22, thereby punching the side of the packaging box 100. After the packaging box 100 is bubbled and punched, the cylinder 3 6 can be started to push up the connected top plate 61, thereby lifting the packaging box 100 placed thereon, and in the process of the packaging box 100 moving up, the small motor 23 The connected driving shaft 24 is synchronously driven to rotate, thereby driving the corresponding frosting belt 25 to operate, so as to smooth out the burrs on the punching holes of the packaging box 100, ensure the smoothness of the edges of the punching holes, make the punching holes smoother and present a better display effect. When the packaging box 100 leaves the placement table 21, that is, when the packaging box 100 moves up to a certain height, the cylinder four 62 is synchronously started and pushes the moving packaging box 100 forward, so that the distance between the packaging box 100 and the operator is shortened to facilitate taking, and then the processed packaging boxes 100 are placed together.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
