Description

Technical Field

[0001] This utility model relates to the technical field of packaging carton production equipment, specifically a flattening device for packaging carton production. Background Technology

[0002] Cardboard boxes are packaging containers made primarily of cardboard (such as corrugated paper, kraft paper, etc.). They are widely used in commodity transportation, warehousing, and display, and have the characteristics of protecting goods, facilitating handling, and being environmentally friendly and recyclable. Cardboard boxes are mainly made of cardboard spliced ​​or folded. Since cardboard often bends due to various factors during the production process, flattening equipment is needed to flatten the cardboard.

[0003] A search revealed that patent application CN202421849159.6 discloses a flattening device for producing packaging cartons, including a feeding device with a supporting device in the middle and a pressing device on top of the supporting device. The supporting device includes a support platform with two blocking cylinders symmetrically installed on its top. Blocks are provided inside the blocking cylinders. A support rod is fixedly installed on one side of the support platform, and a rack is fixedly installed on one side of the support rod. This flattening device for producing packaging cartons, through the design of a pressing box on top of the pressing plate, simultaneously heats the cardboard during the pressing process, improving the dryness of the cardboard and preventing it from bending again, thus enhancing the flattening effect. The design of blocking cylinders to prevent cardboard movement ensures precise cardboard positioning, preventing inertial displacement when the conveyor belt stops, which would affect flattening accuracy and further improve processing precision.

[0004] However, this patent has its shortcomings. The cardboard flattening device lacks a mechanism to flatten the warped edges of the cardboard. When there are warped edges on the cardboard, the flattening process will cause some parts of the cardboard to overlap with the flattened parts, affecting the flattening quality and subsequent use. In addition, the device can only heat and dry the top of the cardboard, resulting in low efficiency in drying the cardboard.

[0005] To address this, we propose a flattening device for the production of packaging cartons. Utility Model Content

[0023] A cylinder 12 is fixedly mounted on the top of the second mounting frame 3. The output end of the cylinder 12 extends into the second mounting frame 3 and is fixedly mounted on a pressure seat 11. The second cylinder 12 drives the pressure seat 11 to descend, facilitating the flattening of the cardboard.

[0024] Working principle: In use, place the cardboard to be flattened on the conveyor belt 7, turn on the motor 5, and the output end of the motor 5 drives the toothed roller 8 to rotate, so that the conveyor belt 7 is driven along the outer side of the two toothed rollers 8, thus conveying the cardboard from right to left on the conveyor belt 7. When the cardboard is conveyed into the first mounting frame 2, the motor 5 stops working. At this time, the output end of the first electric push rod 16 drives the connecting frame 20 to descend to a suitable height, so that multiple rollers 19 press against the center of the cardboard. Then, the output ends of multiple second electric push rods 21 drive multiple U-shaped frames 18. Extending away from the fixing frame 17, multiple rollers 19 roll the cardboard, flattening the four sides of the warped cardboard. Then, the first electric actuator 16 raises the connecting frame 20, and the second electric actuator 21 resets the U-shaped frame 18. At this time, the motor 22 drives the threaded rod 23 to rotate, causing the rack 26 to slide backward. Since the rack 26 is engaged with the gear plate 15, the gear plate 15 drives the rotating shaft 14 and the fixing frame 17 to deflect by 45 degrees. Then, the first electric actuator 16 again drives the multiple rollers 19 to press down onto the cardboard, and the second... The electric actuator 21 drives multiple rollers 19 to extend and roll away from the fixed frame 17, thus flattening the four corners of the cardboard. After flattening, the first electric actuator 16 and the second electric actuator 21 return to their original positions. The motor 22 drives the threaded rod 23 to reverse, causing the rack 26 to return to its original position. The motor 5 continues to work, conveying the cardboard to the heat-conducting plate 10. At this time, multiple heating tubes 13 heat the cardboard, transferring heat to the heat-conducting plate 10. Simultaneously, the cylinder 12 works, driving the pressure seat 11 to press down on the cardboard and flatten it. During the flattening process, the two heat-conducting plates 10 can simultaneously... The top and bottom of the cardboard are heated and dried simultaneously. Circuit connections, mechanical structures, and connection relationships not mentioned in this specification are all conventional technical means in this field, and therefore will not be described in detail. This type of flattening device for packaging carton production is easy to use. The above-mentioned components can flatten the sides and four corners of the cardboard before flattening, avoiding warping of the cardboard and affecting the quality of subsequent flattening. It can also heat the top and bottom of the cardboard simultaneously during the flattening process, thereby further improving the efficiency of cardboard drying.
