Description

Technical Field

[0001] This utility model belongs to the technical field, and in particular relates to a corrugated cardboard box processing creasing and folding device. Background Technology

[0002] Corrugated cardboard boxes are formed by folding corrugated paper to create a box structure. After folding, the boxes have good support and stability, making them suitable for use in the transportation of various goods. However, corrugated paper cannot be folded directly; it usually requires creasing to facilitate folding.

[0003] Patent application CN202420460656.0 discloses a corrugated carton processing creasing and folding device, including a base plate, connecting plates, and a distance control structure. A horizontal frame plate is mounted on top of the base plate. Two sets of support frames, arranged horizontally, are fixedly installed between the base plate and the horizontal frame plate. Two sets of connecting plates, also arranged horizontally, are located at the bottom of the horizontal frame plate. A connecting plate is located at the bottom of the connecting plate. Electric push rods are installed on both the connecting plate and the connecting plate. A liquid storage box is located at the bottom of the connecting plate, and an arc-shaped pressure strip is located at the bottom of the liquid storage box. The distance control structure is located on the horizontal frame plate and the connecting plate. This corrugated carton processing creasing and folding device can precisely wet specific areas of the carton during the creasing process and facilitates adjustment of the distance between the two sets of liquid storage boxes. It can be adapted to the size of the carton, enhancing the device's applicability and practicality.

[0004] Existing technologies use components such as liquid storage boxes and absorbent sponges to moisten the creases, but there are still shortcomings: First, existing creasing and folding devices can only wet the creasing area when creasing corrugated boxes. However, when corrugated cardboard is creasing, the indentation at the creasing area will create a stretching effect on both sides of the creasing. Wetting only the area cannot effectively prevent damage to the carton caused by creasing. Secondly, the existing corrugated carton creasing and folding devices lack the ability to secure the carton during creasing, which can cause the carton to shift during the creasing process and thus affect the overall quality of the carton processing. Finally, different molds are used for creasing different cartons. Existing creasing and folding devices can only creasing a single type of carton and cannot be adapted to different styles of cartons, which is not conducive to the diversified processing of cartons. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this invention provides a corrugated cardboard box crease-pressing and folding device. Through the arrangement of components such as a pressure folding plate, this invention can pre-press and fix the cardboard box, and simultaneously perform atomized moistening treatment on the area around the creases of the cardboard box during the pressing and fixing process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard box processing creasing and folding device, comprising a worktable, a plurality of sliding plates slidably disposed above the worktable, a creasing mold slidably engaged below each sliding plate, side plates fixedly disposed on both sides of each sliding plate, a water tank elastically slidably disposed below each side plate, a folding airbag connected between every two adjacent side plates and the water tank, a downward pressing folding plate fixedly disposed on the outer side wall of each water tank, a plurality of atomizing nozzles communicating with the water tank being disposed above the lower end face of each downward pressing folding plate, a plurality of air inlets being disposed on the upper end face of each water tank, and a one-way air valve being disposed above the upper end face of each air inlet on the upper end face of the side plate.

Each of the downward pressing folding plates is provided with a plurality of connecting through holes that connect the first U-shaped plate and the second U-shaped plate, and each second U-shaped plate is provided with an absorbent sponge inside.

[0008] Optionally, a sliding rod is provided on the upper surface of the water storage tank between every two adjacent air inlets, each sliding rod is slidably connected to its adjacent side plate, and a second spring is provided on the outside of each sliding rod between the sliding rod and the side plate.

[0009] Optionally, each of the indentation molds is provided with an installation groove on the lower end face of the installation groove, and a snap-fit ​​strip is slidably provided inside each of the installation grooves. Each snap-fit ​​strip is fixedly connected to the upper end face of its adjacent indentation mold, and a limit plate can be detachably provided on one side of each installation groove on the side wall of the sliding plate.

[0010] Optionally, each of the mounting slides has multiple limiting slides on its inner top surface, and each limiting slide has a trapezoidal limiting block slidably engaged inside it.

[0012] Optionally, each of the lower pressure plates is provided with multiple anti-slip strips on its lower end surface.

[0013] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) By setting up components such as a water storage tank, a pressure plate and an atomizing nozzle, this utility model can pre-press and fix the corrugated cardboard box when it is being crimped. At the same time as pressing and fixing, it can atomize and moisten the area around the crimping line of the cardboard box, effectively avoiding the problem of damage to the corrugated cardboard box during the crimping process. (2) By setting up the first U-shaped plate, connecting through hole and water-absorbing sponge, this utility model can collect and store the excess water sprayed from the atomizing nozzle when atomizing the corrugated cardboard box, effectively avoiding damage to the cardboard box caused by excess water when atomizing and wetting the cardboard box. (3) By installing components such as sliding grooves, snap-fit ​​strips and trapezoidal limit blocks, this utility model enables the easy replacement of different creasing molds when creasing different styles of cartons, so as to adapt to the production and processing of different styles of cartons.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a corrugated cardboard box processing creasing and folding device includes a workbench 10. Multiple sliding plates 13 are slidably arranged above the workbench 10. A first sliding square rod 12 is slidably arranged above each sliding plate 13. Support frames 11 are provided on the upper surface of the multiple first sliding square rods 12. Air inlets 34 are provided on both sides of each first sliding square rod 12 on the side wall of the support frame 11. Both ends of each first sliding square rod 12 are slidably connected to their adjacent air inlets 34. An anti-slip strip 35 is rotatably arranged inside one side of the air inlet 34 of each first sliding square rod 12. A servo motor for driving the anti-slip strip 35 to rotate is provided on one side of each anti-slip strip 35 on the side wall of the support frame 11. The upper end of the first sliding square rod 12... An electric push cylinder is provided on the surface. The output end of the electric push cylinder passes through the first sliding square rod 12 and is fixedly connected to the upper end surface of the sliding plate 13. Guide rods are provided on both sides of the output end of the electric push cylinder on the upper end surface of the sliding plate 13. Each guide rod is slidably connected to its adjacent first sliding square rod 12. The arrangement of multiple guide rods forms a guiding effect on the vertical sliding of the sliding plate 13. When performing corrugated carton creasing, the carton is first placed on the upper end surface of the workbench 10. Then, multiple servo motors are started. The multiple servo motors drive the anti-slip strips 35 connected to them to rotate, thereby driving the first sliding square rod 12 to slide horizontally inside the support frame 11. The horizontal position of the creasing mold 14 set below the multiple first sliding square rods 12 is adjusted to facilitate the subsequent creasing of the carton.

[0018] Furthermore, such as Figure 3 and Figure 4As shown, each sliding plate 13 is slidably engaged with an indentation mold 14 below it. Side plates 20 are fixedly mounted on both sides of each sliding plate 13. A water tank 21 is elastically slidably mounted below each side plate 20. A folding airbag 22 connects every two adjacent side plates 20 and water tanks 21. A downward-pressing folding plate 23 is fixedly mounted on the outer wall of each water tank 21. Multiple atomizing nozzles 24, communicating with the water tank 21, are mounted above each downward-pressing folding plate 23 on the lower end face of the water tank 21. Each atomizing nozzle... The output ends of the cylinders 24 all face the creasing mold 14. Each water tank 21 has multiple air inlets 34 on its upper surface. Above each air inlet 34, on the upper surface of the side plate 20, is a one-way air valve 25. The one-way air valve 25 supplies air to the cavity formed by the side plate 20, the water tank 21, and the side plate 20. During creasing of the carton, the output ends of the multiple electric push cylinders drive the sliding plate 13 to move vertically downwards. The multiple sliding plates 13 then drive the side plates 20 on both sides to move horizontally downwards, thereby driving the creasing mold 14 to move the cylinders below each side plate 20. The components, including the water tank 21, the pressure folding plate 23, and the atomizing nozzle 24, move downwards. The pressure folding plate 23 first contacts the upper surface of the cardboard box, forming a downward pressure to fix the cardboard box. As the sliding plate 13 continues to press down, the pressure folding plate 23 will drive the water tank 21 to form a compression between the water tank 21 and the side plate 20, thereby compressing the folding airbag 22. This causes the air inside the folding airbag 22 to enter the interior of the water tank 21 through multiple air inlets 34. The increased air pressure inside the water tank 21 will cause the water inside the water tank 21 to flow through... Water is sprayed from multiple atomizing nozzles 24, which then fall onto the upper surface of the carton between the two lower pressing folds 23, wetting the upper surface near the creasing area. Some of the water is sprayed onto the side wall of the creasing mold 14, and then slides down the side wall to the edge of the creasing mold 14. This further increases the wetness of the creasing area when the creasing mold 14 creasing the carton, thus effectively preventing damage to the carton during creasing.

[0019] Furthermore, such as Figure 4 As shown, each pressure plate 23 has multiple anti-slip strips 35 on its lower end surface. The multiple anti-slip strips 35 increase the friction between the lower end surface of the pressure plate 23 and the carton, thereby further forming a stable downward pressure and fixation of the carton.

[0020] Furthermore, such as Figure 3 and Figure 4As shown, each downward folding plate 23 has a first U-shaped plate 28 on its inclined sidewall. Each first U-shaped plate 28 has a second U-shaped plate 29 on one side of its inner end face. Each downward folding plate 23 has multiple connecting holes 30 on its inclined sidewall, connecting the first U-shaped plate 28 and the second U-shaped plate 29. Each second U-shaped plate 29 has an absorbent sponge 31 inside. When the creasing and folding device creasing the carton, some of the water mist sprayed from the multiple atomizing nozzles 24 falls onto the inclined end face of the downward folding plate 23. To prevent this water from sliding down to the lower end face of the downward folding plate 23... To prevent further wetting and damage to the cardboard box, the first U-shaped plate 28 collects and stores the water droplets falling onto the inclined end face of the lower pressure folding plate 23. To avoid excessive water splashing outwards when the cardboard box is crimped multiple times, the second U-shaped plate 29, connecting holes 30, and absorbent sponge 31 are used. When the water level inside the first U-shaped plate 28 is too high, the water flows into the second U-shaped plate 29 through the multiple connecting holes 30, while the absorbent sponge 31 absorbs and stores the water. Workers only need to periodically squeeze the water out of the absorbent sponge 31.

[0021] Furthermore, such as Figure 3 and Figure 4 As shown, a sliding rod 26 is provided on the upper surface of the water tank 21 between every two adjacent air inlets 34. Each sliding rod 26 is slidably connected to its adjacent side plate 20. A second spring 27 is provided on the outside of each sliding rod 26 between the sliding rod 26 and the side plate 20. The arrangement of multiple sliding rods 26 forms a guiding effect on the relative sliding between the water tank 21 and the side plate 20. The arrangement of multiple second springs 27 can form a spring through their own elastic tension after the creasing die 14 and the lower folding plate 23 and other components have completed the creasing process of the carton. The stretching of the tops of the multiple sliding rods 26 increases the distance between the side plate 20 and the water tank 21. At this time, under the stretching action of the side plate 20 and the water tank 21, the volume of the cavity formed by the side plate 20, the water tank 21 and the folded airbag 22 increases, the internal air pressure decreases, and external air enters through the one-way air valve 25. When the side plate 20 and the water tank 21 compress the folded airbag 22, the multiple one-way air valves 25 can ensure that the air inside the folded airbag 22 does not leak out, thereby ensuring that the pressure inside the water tank 21 continues to increase.

[0022] Furthermore, such as Figure 5 and Figure 6As shown, each creasing mold 14 has a mounting groove 15 on its lower end face above the mounting groove 15. Each mounting groove 15 has a snap-fit ​​strip 16 slidably installed inside it. Each snap-fit ​​strip 16 is fixedly connected to the upper end face of its adjacent creasing mold 14. A limit plate 33 can be detachably installed on one side of each mounting groove 15 on the side wall of the sliding plate 13. When creasing different styles of cartons, the creasing mold 14 can be disassembled by removing the bolts connecting the sliding plate 13 and the limit plate 33, and then a suitable creasing mold 14 can be replaced to ensure creasing treatment for different styles of cartons.

[0023] Furthermore, such as Figure 5 As shown, each mounting groove 15 has multiple limiting grooves 17 on its inner top surface. Each limiting groove 17 has a trapezoidal limiting block 18 slidably engaged inside it. A first spring 19 is provided between the limiting groove 17 and the trapezoidal limiting block 18 inside each limiting groove 17. The trapezoidal limiting blocks 18 are inclined on one side wall near the limiting plate 33, facilitating the horizontal insertion of the engaging strip 16 into the mounting groove 15 when the indentation mold 14 is replaced. One end of the engaging strip 16 can be horizontally supported by the inclined surface of each trapezoidal limiting block 18, allowing the trapezoidal limiting block 18 to slide upwards into the limiting groove 17. Inside 7, when creasing the carton, the bottoms of multiple creasing molds 14 first contact the upper surface of the carton. Then, as the sliding plate 13 continues to move downward, it will create pressure between multiple trapezoidal limiting blocks 18 and the snap-fit ​​strip 16. Under the elastic tension of multiple first springs 19, the trapezoidal limiting blocks 18 will be driven to form multiple points of elastic downward pressure on the upper surface of the snap-fit ​​strip 16. This allows the creasing molds 14 to act as a buffer between the sliding plate 13 and the creasing molds 14 when creasing the carton, so that the downward pressure of the creasing molds 14 increases slowly when creasing the carton, effectively preventing the creasing molds 14 from crushing the carton.

[0024] The aforementioned servo motors and electric push cylinders are all existing technologies, and this solution will not elaborate on them. In actual production, damping pads are provided at both ends of the first and second springs to absorb the vibrations that may be generated during the operation of the springs.

[0025] Finally, it should be noted that the corrugated cardboard box processing creasing and folding device of this utility model needs to protect the various mechanical structures and related motion logic in this solution. Therefore, it does not elaborate on the various sensors, detectors and driving components required for the actual operation of the various mechanical structures. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can be completed using conventional technical means. As long as the beneficial effects or the specific actions during the above work can be achieved, they can be implemented. This solution does not impose too many restrictions.

[0026] Furthermore, the electric push cylinder, servo motor, and spring in the corrugated cardboard box processing creasing and folding device of this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
