Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging paper box production technology, specifically to an embossing device for producing environmentally friendly packaging paper boxes. Background Technology
[0002] Eco-friendly packaging boxes are packaging boxes made from environmentally friendly materials. Their main characteristics are the use of recyclable and biodegradable paper materials, making them environmentally friendly and sustainable. During the production of eco-friendly packaging boxes, the sheet paper needs to be creasing to facilitate later shaping.
[0003] As described in Chinese patent application CN202321694037.X, a creasing device for processing packaging paper boxes includes: "A moving component, wherein fixed plates are fixedly connected to both the front and rear sides of the moving component, and electric push rods are fixedly connected to the opposite surfaces of the two fixed plates. Mounting plates are fixedly connected to the output ends of the two electric push rods on the front side and the two electric push rods on the rear side. Rotating shafts are fixedly connected to the lower surfaces of the two mounting plates, and rollers are rotatably connected to the surfaces of the rotating shafts. A fixed frame is fixedly connected to the surface of the moving component, and a creasing component is rotatably connected to the inner wall of the fixed frame. This invention, by setting rollers, places the packaging paper box between the two mounting plates and limits the position of the packaging paper box by the rollers, preventing the packaging paper box from shifting position when the moving component moves, thus avoiding inaccurate creasing positions and affecting creasing precision."
[0004] When we simulated the use of the published patents retrieved above, we found that the technology still has certain shortcomings:
[0005] During creasing, the sides of the cardboard are limited by structures such as electric push rods, mounting plates, rotating shafts, and rollers to ensure accurate creasing positions. However, the limiting of the front end of the cardboard material is neglected. In other words, the front end of the cardboard material cannot be positioned, making it difficult to position the cardboard material when it enters the fixed frame and is below the creasing block. This means that the stationary position of the cardboard material is difficult to control, which can lead to errors in the creasing position when creasing the same batch of cardboard material. This affects the shape of the final product and makes it difficult to form packaging boxes due to incorrect creasing positions. Utility Model Content
[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a creasing device for producing environmentally friendly packaging paper boxes, comprising a workbench, a conveyor belt installed on the inner side of the workbench, and a limit frame and a support frame fixed sequentially from front to back on the top of the workbench. A support plate fixed to the workbench is provided on the inner side of the conveyor belt. Two width limit plates driven by a servo motor are installed on the inner side of the limit frame, and the two width limit plates are located above the conveyor belt. A cylinder is installed on the top of the support frame, and the power output shaft of the cylinder moves through the support frame and is fixed to a creasing plate, which is located above the conveyor belt.

[0009] As a further embodiment of this utility model: displacement sliders are fixed at the bottom of both the left and right sides of the limiting frame 2. The two displacement sliders are slidably connected in the two displacement grooves respectively, and one displacement slider is slidably sleeved with the fixed rod, while the other displacement slider is threadedly sleeved with the lead screw.
[0010] As a further embodiment of this utility model: both sides of the top of the length limiting plate are fixed with limiting slide rods, and the top of the limiting slide rods can be moved through the top of the limiting frame two.
[0011] As a further embodiment of this utility model: the two ends of the support plate are respectively fixed to the two sides of the inner wall of the workbench, the top of the support plate is slidably attached to the conveyor belt, and the support plate is located directly below the indentation plate.
[0012] As a further embodiment of this utility model: the servo motor three is installed on the top of one side of the limiting frame one, the power output shaft of the servo motor three movably passes through the limiting frame one and is connected to a double threaded rod, the double threaded rod has two opposite threads on its body, and each thread is threaded with a guide slider, the guide slider is placed in the guide groove opened in the inner top wall of the limiting frame one, and two width limiting plates are respectively fixed to the bottom of the two guide sliders.
[0013] As a further embodiment of this utility model: a servo motor is also installed on one side of the workbench. The power output shaft of the servo motor passes through the workbench and is connected to a transmission roller. A transmission roller is rotatably connected to the workbench at a position away from the transmission roller.

[0014] As a further embodiment of this utility model: guide blocks are fixed on both sides of the indentation plate, and the guide blocks are slidably connected in the guide groove opened on the inner wall of the support frame.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] I. In this application, by designing a limiting frame one and a width limiting plate, the left and right positions of the cardboard material of the packaging box can be limited, preventing the cardboard material from shifting and causing the indentation to tilt. In conjunction with a limiting frame two and a length limiting plate, a limiting structure can be formed at the front end of the cardboard material, which can position the stationary point of the cardboard material to ensure that the indentations of multiple cardboard materials are in the same position, which facilitates subsequent forming and ensures that the quality of the packaging boxes formed from the same batch of cardboard material is consistent.
[0017] Second, in this application, the position of the limiting frame 2 can also be changed by activating the servo motor 2, so that it moves away from or closer to the support frame, thereby changing the positioning position of the front end of the cardboard material, so as to change the requirements of different indentation points for different batches of cardboard material, thereby effectively improving the applicability of the device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-6 A creasing device for producing environmentally friendly packaging paper boxes includes a workbench 1, a conveyor belt 3 installed on the inner side of the workbench 1, and a limit frame 4 and a support frame 5 fixed sequentially from front to back on the top of the workbench 1. A support plate 12 fixed on the workbench 1 is provided on the inner side of the conveyor belt 3. Two width limit plates 14 driven by servo motors 8 are installed on the inner side of the limit frame 4, and the two width limit plates 14 are located above the conveyor belt 3. A cylinder 10 is installed on the top of the support frame 5, and the power output shaft of the cylinder 10 moves through the support frame 5 and is fixed with a creasing plate 11, which is located above the conveyor belt 3. A limit frame 6 driven by servo motors 7 and sliding on the workbench 1 is provided on the top of the workbench 1 and behind the support frame 5. An electric push rod 9 is installed on the top of the limit frame 6, and the power output shaft of the electric push rod 9 moves through the limit frame 6 and is fixed with a length limit plate 15.
[0028] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, the top of the workbench 1 is provided with two displacement grooves 101. A fixed rod 17 is fixed in one displacement groove 101, and a lead screw 701 is rotatably connected in the other displacement groove 101. A servo motor 7 is installed on one side of the workbench 1, and the power output shaft of the servo motor 7 moves through the workbench 1 and is connected to the lead screw 701 for transmission. Displacement sliders 601 are fixed at the bottom of both sides of the limit frame 6. The two displacement sliders 601 are slidably connected in the two displacement grooves 101 respectively, and one displacement slider 601 is slidably sleeved with the fixed rod 17, and the other displacement slider 601 is threadedly sleeved with the lead screw 701.
[0029] Specifically, after the servo motor 7 is started, the rotation of the lead screw 701 drives the displacement slider 601, which is threaded onto it, to move in the corresponding displacement groove 101, thereby driving the limit frame 6 to move on the worktable 1. Meanwhile, another displacement slider 601 on the top of the limit frame 6 moves in another displacement groove 101 and is limited and supported by the fixing rod 17, which can ensure the stability of the limit frame 6 during movement.
[0030] Please see Figure 3 In this embodiment, limiting slide rods 16 are fixed on both sides of the top of the length limiting plate 15, and the top of the limiting slide rod 16 moves through the top of the limiting frame 2 6.
[0031] Specifically, by setting two limiting slide rods 16 on the length limiting plate 15, the length limiting plate 15 can be guaranteed to have good stability and orientation when it moves up and down, and the straightness of the indentation can be guaranteed.
[0032] Please see Figure 5 and Figure 6 In this embodiment, the two ends of the support plate 12 are respectively fixed to the two sides of the inner wall of the workbench 1, the top of the support plate 12 is slidably attached to the conveyor belt 3, and the support plate 12 is located directly below the indentation plate 11.
[0033] Specifically, the support plate 12 can provide support at the indentation position, preventing the bottom of the indentation plate 11 from becoming soft due to the conveyor belt 3 during indentation, thereby ensuring the depth and quality of the indentation.
[0034] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, the servo motor 38 is installed on the top of one side of the limiting frame 4. The power output shaft of the servo motor 38 moves through the limiting frame 4 and is connected to a double threaded rod 801. The double threaded rod 801 has two opposite threads on its body, and each thread is threaded with a guide slider 13. The guide slider 13 is placed in the guide groove opened in the inner top wall of the limiting frame 4. Two width limiting plates 14 are respectively fixed to the bottom of the two guide sliders 13.
[0035] Specifically, after the servo motor 38 starts, it can drive the double threaded rod 801 to rotate. When the double threaded rod 801 rotates, it can drive the two guide sliders 13 to move closer or further apart in the guide groove, thereby driving the two width limiting plates 14 to move closer or further apart to adapt to cardboard materials of different widths.
[0036] Please see Figure 1 and Figure 6 In this embodiment, a servo motor 1 2 is also installed on one side of the workbench 1. The power output shaft of the servo motor 1 2 passes through the workbench 1 and is connected to a transmission roller 201. A transmission roller 2 is rotatably connected on the workbench 1 at a position away from the transmission roller 201. A transmission belt 3 is connected between the transmission roller 1 201 and the transmission roller 2.
[0037] Specifically, after the servo motor 12 starts, it can drive the transmission roller 201 to rotate, thereby driving the transmission belt 3 to rotate and realizing the conveying of paperboard material, while the transmission roller 2 connects to the other side of the transmission belt 3.
[0038] Please see Figure 1 and Figure 5 In this embodiment, guide blocks are fixed on both sides of the indentation plate 11, and the guide blocks are slidably connected in the guide groove opened on the inner wall of the support frame 5.
[0039] Specifically, the two sides of the indentation plate 11 are slidably connected to the guide groove on the support frame 5 through guide blocks, which can ensure the stability of the indentation plate 11 during movement.
[0040] Environmentally friendly packaging boxes are made of cardboard before molding. The purpose of creasing is to facilitate subsequent bending and shaping along the creasing lines. When using them:
[0041] First, start the servo motor 2 7. The power output shaft of the servo motor 2 7 drives the lead screw 701 to rotate. The rotation of the lead screw 701 causes the entire limit frame 2 6 to slide on the top of the worktable 1, thereby causing the length limit plate 15 to change the distance between it and the creasing plate 11. The larger the distance, the farther the creasing is from the front end of the cardboard material. The smaller the distance, the closer the creasing is to the front end of the cardboard material. Then start the electric push rod 9. The power output shaft of the electric push rod 9 pushes the length limit plate 15 down and onto the conveyor belt 3.
[0042] Start the servo motor 38. The power output shaft of the servo motor 38 drives the double threaded rod 801 to rotate. When the double threaded rod 801 rotates, it drives the two width limiting plates 14 to move closer to each other or further away from each other. When they move closer to each other, they can limit the width of the cardboard material. When they move further away from each other, they can limit the width of the cardboard material.
[0043] By placing the cardboard material on the conveyor belt 3, the left and right sides of the cardboard material are attached to the inner sides of the two width limiting plates 14. The two width limiting plates 14 limit the cardboard material to prevent it from shifting. When the front end of the cardboard material is attached to the length limiting plate 15, the positioning of the indentation position of the cardboard material is achieved. Then, the servo motor 2 can be turned off to stop the transmission of the conveyor belt 3 and keep the cardboard material in a static and stable state. The cylinder 10 is started, and the power output shaft of the cylinder 10 pushes the indentation plate 11 to move down, so that the bottom protrusion of the indentation plate 11 can be used to indent the cardboard material.
[0044] After the creasing is completed, the length limit plate 15 is raised by the start of the electric push rod 9, the servo motor 2 is started, the transmission belt 3 is rotated again, and the creasing paperboard material is exported from the other side of the workbench 1. After that, the staff can continue to creasing the same batch of paperboard material according to the above operation.
[0045] When the width of different batches of cardboard material changes, the staff can adapt it by changing the position between the two width limiting plates 14. When the position requirements of the indentation points of different batches of cardboard material are different, the staff can adapt it by changing the position of the limiting frame 2 6.
[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
