Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, specifically to an embossing machine for packaging box production. Background Technology

[0002] In modern life, food, electrical appliances and other items are mostly packaged in boxes during transportation. These boxes are generally made of white cardboard, kraft paper or corrugated paper. In the production and processing of cardboard boxes, in order to make them fold into boxes more quickly, creasing machines are usually used to press creases on the cardboard, and then the cardboard is folded into a box through the creases, thus completing the processing of the cardboard box.

[0003] Most current creasing machines have a traditional structural design. A conveyor transports the cardboard into the creasing machine, where pressure rollers crease the cardboard. However, since the creasing process is dynamic, the cardboard may float to varying degrees when entering or leaving the creasing box, affecting the creasing accuracy. If the floating of the cardboard is not stabilized after creasing and when it is transferred out of the creasing box, it may cause abnormal cardboard transmission, affecting the automated creasing operation and consequently impacting the production efficiency and pass rate of packaging boxes. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an embossing machine for packaging box production.

[0005] This utility model discloses a creasing machine for packaging box production, including a creasing box and a conveyor. The creasing box is equipped with an upper pressure roller and a lower pressure roller, and the lower pressure roller is driven by a motor. The upper pressure roller and the lower pressure roller are spaced apart to form a creasing station. The creasing box has material inlets on both sides, and the two material inlets are respectively located on both sides of the creasing station. There are two conveyors, which are respectively located on the side of the two material inlets that are far apart from each other. The creasing box has cantilever arms installed on both sides, and the cantilever arms are located above the adjacent material inlets. The bottom of the cantilever arms is equipped with a pressure stabilizing component to prevent the cardboard from floating, and the distance between the pressure stabilizing component and the conveyor section of the conveyor is adjustable.

[0006] As a further optimization of this utility model, the number of voltage stabilizing components is multiple, and the multiple voltage stabilizing components are evenly distributed along the length direction of the cantilever, and the connection of the multiple voltage stabilizing components is consistent with the conveying direction of the conveyor.

[0007] As a further optimization of this utility model, two cantilever arms are installed on both sides of the indentation box, and the two cantilever arms are symmetrically distributed above the adjacent material inlets.

[0008] As a further optimization of this utility model, the distance between the two cantilever arms located on the same side of the indentation box is adjustable.

[0009] As a further optimization of this utility model, the front and back of the indentation box are provided with vertically distributed movable grooves. An adjusting bolt is installed at the upper end of the movable groove. Bearing seats are provided at both ends of the upper pressure roller. The bearing seats are slidably disposed inside the adjacent movable grooves, and the height of the bearing seats can be adjusted by adjusting the adjusting bolt.

[0010] As a further optimization of this utility model, the conveyor is a belt conveyor, and the conveyor roller shaft end of the conveyor is connected to the shaft end of the lower pressure roller through a belt and a pulley.

[0011] As a further optimization of this utility model, the voltage stabilizing component includes a fixed plate, a voltage stabilizing roller, and a slider. There are two fixed plates installed at the bottom of the cantilever. A slider is installed on each of the two fixed plates. The two sliders are arranged opposite each other and their height is adjustable. The voltage stabilizing roller is disposed between the two sliders. The two ends of the roller shaft of the voltage stabilizing roller are rotatably connected to the adjacent sliders respectively, and the roller shaft axis of the voltage stabilizing roller is perpendicular to the transmission direction of the conveyor.

[0012] As a further optimization of this utility model, the two fixed plates are provided with grooves on their opposite sides that are adapted to the slider. Vertically distributed fixed rods are installed in the grooves. The slider is slidably mounted on the fixed rods, and the two sides of the slider are slidably connected to the inner walls of the two sides of the groove. A spring is mounted on the fixed rod, and the two ends of the spring are fixedly connected to the upper surface of the slider and the lower surface of the groove, respectively.

[0013] The embossing machine for packaging box production proposed in this utility model has the following beneficial effects:

[0014] This invention utilizes a pressure-stabilizing assembly installed above the material inlets on both sides of the creasing box. The rotating design of the pressure-stabilizing rollers, combined with their pressure-pressing effect on the upper surface of the cardboard during transport, prevents cardboard floating without affecting normal transport. Through a combination of slider, fixed rod, and spring, the pressure-stabilizing rollers drive the slider to move up and down along the fixed rod when pressing cardboard of different thicknesses. The springs undergo elastic deformation, allowing the pressure-stabilizing rollers to adaptively adjust their height according to the cardboard thickness, thereby regulating the pressure applied to the cardboard. This achieves stable pressure during both pre- and post-crimping transport, preventing cardboard floating and ensuring creasing accuracy. This facilitates normal cardboard transport and automated creasing, ultimately improving the production efficiency and yield rate of packaging boxes.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] Please see Figure 1 and Figure 2 A creasing machine for packaging box production includes a creasing box 1 and a conveyor 2. The creasing box 1 is equipped with an upper pressure roller 3 and a lower pressure roller 4. The lower pressure roller 4 is driven by a motor 5. The upper pressure roller 3 and the lower pressure roller 4 are spaced apart to form a creasing station. The creasing box 1 has a material port 12 on both sides, and the two material ports 12 are respectively set on both sides of the creasing station. There are two conveyors 2, which are respectively set on the side of the two material ports 12 that are far apart from each other. The output shaft of the motor 5 is connected to the shaft end of the lower pressure roller 4 through a transmission structure, thereby driving the lower pressure roller 4 to rotate. The conveyor 2 transports the cardboard through the material port 12 on one side to the creasing station. The cardboard enters between the upper pressure roller 3 and the lower pressure roller 4. The creasing on the outer periphery of the upper pressure roller 3 and the lower pressure roller 4 is used to squeeze the surface of the cardboard, thereby completing the creasing treatment of the cardboard surface.

[0027] like Figure 2 As shown, cantilever arms 6 are installed on both sides of the creasing box 1. The cantilever arms 6 are positioned above the adjacent feed inlets 12. A pressure stabilizing component 7 is installed at the bottom of the cantilever arms 6 to prevent the cardboard from floating. The distance between the pressure stabilizing component 7 and the transmission part of the conveyor 2 is adjustable. The height of the pressure stabilizing component 7 can be adjusted by an automatic adjustment structure such as a cylinder or a hydraulic cylinder or by a manual adjustment structure, so as to stabilize cardboard of different thicknesses. This prevents the cardboard from floating when entering and leaving the creasing box 1, which helps to improve the accuracy of the actual creasing operation and thus improve the production quality and pass rate of the packaging box.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, there are multiple pressure stabilizing components 7, which are evenly distributed along the length of the cantilever 6. The connection line of the multiple pressure stabilizing components 7 is consistent with the conveying direction of the conveyor 2. When the conveyor 2 conveys the cardboard to the area below the pressure stabilizing components 7, the multiple pressure stabilizing components 7 press and cover the upper surface of the cardboard. At the same time, the rotation of the multiple pressure stabilizing components 7 can assist the cardboard in its transmission, further improve the stability of the cardboard transmission, and prevent floating during the creasing operation.

[0029] Furthermore, such as Figure 4 As shown, the pressure stabilizing assembly 7 includes a fixed plate 71, a pressure stabilizing roller 72, and a slider 73. There are two fixed plates 71 installed at the bottom of the cantilever 6. Each of the two fixed plates 71 is equipped with a slider 73. The two sliders 73 are arranged opposite each other and their height is adjustable. The pressure stabilizing roller 72 is located between the two sliders 73. The two ends of the roller shaft of the pressure stabilizing roller 72 are rotatably connected to the adjacent sliders 73 respectively. The axis of the roller shaft of the pressure stabilizing roller 72 is perpendicular to the transmission direction of the conveyor 2. The height of the slider 73 can be adjusted manually or automatically to adjust the distance between the pressure stabilizing roller 72 and the transmission surface of the conveyor 2, so as to facilitate the pressing of cardboard of different thicknesses. The two ends of the roller shaft of the pressure stabilizing roller 72 are rotatably connected to the adjacent sliders 73 through bearings, which can ensure the smooth rotation of the pressure stabilizing roller 72 and facilitate the pressure stabilizing transmission of cardboard.

[0030] Furthermore, such as Figure 4 As shown, the opposing surfaces of the two fixed plates 71 are provided with grooves 74 that are adapted to the slider 73. Vertically distributed fixed rods 75 are installed in the grooves 74. The slider 73 is slidably mounted on the fixed rods 75, and the two sides of the slider 73 are slidably connected to the inner walls of the two sides of the groove 74. A spring 76 is mounted on the fixed rod 75, and the two ends of the spring 76 are fixedly connected to the upper surface of the slider 73 and the lower surface of the groove 74, respectively. When the cardboard is transferred to the pressure stabilizing roller 72, under the action of the arc surface of the outer circumference of the pressure stabilizing roller 72, the cardboard will push the pressure stabilizing roller 72 upward and transfer it to the lower part of the pressure stabilizing roller 72. The pressure stabilizing roller 72 then drives the slider 73 to move upward along the groove 74. At the same time, the slider 73 moves upward along the fixed rod 75 and squeezes the spring 76. By utilizing the elastic deformation of the spring 76, the pressure stabilizing roller 72 can achieve adaptive pressure stabilization for cardboard of different thicknesses.

[0031] Specifically, such as Figure 3 As shown, since the edges of the cardboard are more likely to float up and down or curl up during the cardboard transfer process, two cantilever arms 6 are installed on both sides of the creasing box 1, and the two cantilever arms 6 are symmetrically distributed above the adjacent feed inlets 12, which facilitates the creasing of the cardboard on both sides and helps to improve the stability of the cardboard transfer.

[0032] Furthermore, the distance between the two cantilever arms 6 located on the same side of the creasing box 1 is adjustable and can be adjusted by various horizontal displacement adjustment structures. For example, a slide rail is installed on the side of the creasing box 1, and the slide rail is horizontally set above the feed inlet 12. A movable block is installed at the tail end of the cantilever arm 6, and the movable block is slidably connected to the slide rail. The movable block is driven by the cantilever arm 6 to slide along the slide rail so as to adjust the distance between the two cantilever arms 6, thereby facilitating edge creasing of cardboard of different widths and improving practicality.

[0033] Specifically, such as Figure 1 As shown, the front and back of the indentation box 1 are provided with vertically distributed movable grooves 8. An adjusting bolt 10 is installed at the upper end of the movable groove 8. Bearing seats 9 are provided at both ends of the upper pressure roller 3. The bearing seats 9 are slidably disposed inside the adjacent movable grooves 8. The height of the bearing seats 9 can be adjusted by adjusting the adjusting bolt 10. The adjusting bolt 10 is threaded onto the top of the indentation box 1. The handle end of the adjusting bolt 10 faces upward, and the screw end of the adjusting bolt 10 extends downward into the movable groove 8 and is rotatably connected to the upper end face of the bearing seat 9. By rotating the adjusting bolt 10, the height of the bearing seat 9 can be adjusted, thereby adjusting the distance between the upper pressure roller 3 and the lower pressure roller 4, and thus adjusting the indentation pressure.

[0034] Specifically, the conveyor 2 is a belt conveyor, and the conveyor roller shaft end of the conveyor 2 is connected to the shaft end of the lower pressure roller 4 through the belt and pulley 11. While the motor 5 drives the lower pressure roller 4 to rotate, it can also drive the conveyor 2 to run at the same time, so as to realize the automated creasing operation of the paperboard.

[0035] It should be noted that the rotation direction of the lower pressure roller 4 is the same as that of the conveyor roller of the conveyor 2. This design is conducive to the fast and stable transmission of paperboard and is suitable for the processing of paperboard with shallow indentations.

[0036] In summary, the creasing machine for packaging box production proposed in this utility model, by installing pressure stabilizing components 7 above the material inlets 12 on both sides of the creasing box 1, utilizes the rotational design of the pressure stabilizing roller 72, combined with the pressure stabilizing roller 72 pressing on the upper surface of the cardboard during transmission, to prevent the cardboard from floating without affecting the normal transmission of the cardboard. Through the combined design of slider 73, fixed rod 75, and spring 76, when the pressure stabilizing roller 72 presses on cardboard of different thicknesses, the pressure stabilizing roller 72 can drive the slider 73 to move up and down along the fixed rod 75, while the spring 76 undergoes elastic deformation, thereby allowing the pressure stabilizing roller 72 to adaptively adjust its height according to the cardboard thickness, and thus adjust the pressure of the pressure stabilizing roller 72 on the cardboard. This achieves pressure stabilization for the transmission of cardboard before and after creasing, preventing cardboard floating from affecting the creasing accuracy, which is beneficial for the normal transmission of cardboard and automated creasing, thereby improving the production efficiency and pass rate of packaging boxes.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
