Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and in particular to a cardboard box flattening device. Background Technology

[0002] In the carton production process, flattening is a crucial step, directly impacting the quality of subsequent processes such as die-cutting, printing, and gluing. For example, during die-cutting, an uneven surface can lead to decreased precision and even problems like burst lines or unclear creases. Simultaneously, flattened cartons are more stable during printing and gluing, improving production efficiency and product quality. Furthermore, flattening eliminates waviness or creases on the carton surface, enhancing its overall structural strength. For instance, flattened corrugated cardboard bonds better with adhesives, improving the overall pressure resistance of the carton.

[0003] In existing technologies, during the movement or pressing process of traditional equipment, cartons are prone to shifting or tipping over, especially when the cartons are stacked high. The lack of an effective lateral restraint structure results in poor flattening effect and may even damage the cartons. Moreover, the lack of a buffer mechanism during the pressing of cartons makes them prone to deformation or breakage due to excessive instantaneous pressure. Therefore, we propose a carton flattening device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a carton flattening device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A carton flattening device includes two frames and a carton placement plate. The top of the two frames is fixedly connected to the same top plate. Two cylinders are fixedly connected to the top of the top plate. The bottom of the output ends of the two cylinders is fixedly connected to the same mounting plate. The outer wall of the mounting plate has multiple through holes. T-shaped rods are slidably connected to the inner walls of the multiple through holes. The bottom of the multiple T-shaped rods is fixedly connected to the same lower pressure plate. The outer walls of the multiple T-shaped rods are fitted with first springs. The top of the lower pressure plate is fixedly connected to multiple sliding rods. The bottom of the carton placement plate is fixedly connected to a guide plate. A U-shaped guide rail is slidably fitted to the outer wall of the guide plate. The top of the carton placement plate is provided with a limiting component.

[0007] Preferably, the limiting component includes two rectangular plates. The top of the carton placement plate is slidably connected to the bottom of the two rectangular plates. Hollow vertical plates are fixedly connected to the top of both rectangular plates and the carton placement plate. Multiple second springs are fixedly connected inside the three vertical plates. The outer wall of the carton placement plate has four strip grooves. Threaded rods are slidably connected to the inner walls of the four strip grooves. Nuts are threaded onto the outer walls of the four threaded rods. The four threaded rods are fixedly connected to the bottom of the two rectangular plates in pairs. Side plates are slidably connected to the inside of the three vertical plates. The bottom of the three side plates is fixedly connected to the top of the multiple second springs. The limiting component limits the carton.

[0008] Preferably, the top plate has two sliding holes at its top, and the inner walls of the two sliding holes are slidably connected to the outer walls of the output ends of the two cylinders respectively. The two cylinders are connected by using a Y-shaped connector so that they bear the same pressure and thus achieve synchronization.

[0009] Preferably, the bottom of each of the multiple first springs is fixedly connected to the top of the mounting plate, and the top of each of the multiple first springs is fixedly connected to the outer wall of each of the multiple T-shaped rods. The multiple first springs play a buffering role when the lower pressure plate is pressed down.

[0010] Preferably, the outer wall of the mounting plate has multiple circular holes, and the inner walls of the multiple circular holes are slidably connected to the outer walls of multiple sliding rods, so that the lower pressure plate can move up and down by setting multiple sliding rods.

[0011] Preferably, the bottom of the carton placement plate is fixedly connected with multiple self-locking wheels, and the carton placement plate moves through the multiple self-locking wheels.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] In this solution, cardboard boxes are stacked on a movable cardboard box placement board, and stable positioning and support are achieved through the cooperation of self-locking wheels and U-shaped guide rails. Three vertical plates and adjustable side plates limit the cardboard boxes on three sides.

[0014] The adjustment mechanism using threaded rods and rectangular plates allows for flexible adaptation to cartons of varying widths. During the pressing process, a buffer mechanism consisting of a T-shaped rod and a first spring effectively reduces the initial impact, while the side plate supported by the second spring elastically descends during the pressing process, ensuring smooth flattening and preventing damage to the cartons.

[0023] Depend on Figures 1-5As shown, a carton flattening device is disclosed, comprising two frames 1 and a carton placement plate 9. The top of the two frames 1 is fixedly connected to the same top plate 2, and the top of the top plate 2 is fixedly connected to two cylinders 3. The top plate 2 supports the two cylinders 3. The top of the top plate 2 has two sliding holes, and the inner walls of the two sliding holes are slidably connected to the outer walls of the output ends of the two cylinders 3 respectively. The bottom of the output ends of the two cylinders 3 is fixedly connected to the same mounting plate 4, and the two cylinders 3 drive the mounting plate 4 to move up and down.

[0024] The outer wall of the mounting plate 4 has multiple through holes, and the inner walls of the multiple through holes are slidably connected to T-shaped rods 5. The bottom of the multiple T-shaped rods 5 is fixedly connected to the same lower pressure plate 7. The outer walls of the multiple T-shaped rods 5 are fitted with first springs 6. The first springs 6 work with the T-shaped rods 5 to provide elastic support for the lower pressure plate 7. The bottom of the multiple first springs 6 is fixedly connected to the top of the mounting plate 4. The top of the multiple first springs 6 is fixedly connected to the outer walls of the multiple T-shaped rods 5 respectively. The top of the lower pressure plate 7 is fixedly connected to multiple sliding rods 8. The outer wall of the mounting plate 4 has multiple round holes, and the inner walls of the multiple round holes are slidably connected to the outer walls of the multiple sliding rods 8 respectively. The lower pressure plate 7 is moved with the assistance of the multiple sliding rods 8.

[0025] A guide plate 10 is fixedly connected to the bottom of the carton placement plate 9. A U-shaped guide rail 11 is slidably fitted on the outer wall of the guide plate 10. Multiple self-locking wheels 13 are fixedly connected to the bottom of the carton placement plate 9. The bottom of the carton placement plate 9 is supported by the guide plate 10 and the U-shaped guide rail 11. The auxiliary carton placement plate 9 is located below the lower pressure plate 7. The two frames 1 and the U-shaped guide rail 11 are fixed to the ground by existing expansion bolts.

[0026] The top of the carton placement plate 9 is provided with a limiting component, which includes two rectangular plates 15. The top of the carton placement plate 9 is slidably connected to the bottom of the two rectangular plates 15. Hollow vertical plates 14 are fixedly connected to the top of the two rectangular plates 15 and the carton placement plate 9. Multiple second springs 17 are fixedly connected inside the three vertical plates 14. The three vertical plates 14 are elastically supported by the multiple second springs 17 and can move downward after being compressed.

[0027] The outer wall of the carton placement plate 9 has four strip grooves 12. The inner wall of each of the four strip grooves 12 is slidably connected to a threaded rod 16. The outer wall of each of the four threaded rods 16 is threaded with a nut. The four threaded rods 16 are fixedly connected to the bottom of two rectangular plates 15 in pairs. The top of the threaded rods 16 is fixedly connected to the bottom of the rectangular plates 15. The rectangular plates 15 can move left and right through the two threaded rods 16 at the bottom.

The bottom of each of the three side plates 18 is fixedly connected to the top of a plurality of second springs 17.

[0028] Working principle: During use, cartons are stacked on the carton placement plate 9, which is moved by four self-locking wheels 13 at the bottom until it reaches the position of the U-shaped guide rail 11. This allows the guide plate 10 to slide into the U-shaped guide rail 11, increasing the stability of the carton placement plate 9. The cartons are blocked by three vertical plates 14 and three side plates 18, limiting the three sides of the cartons and preventing them from sliding to the sides or back during subsequent flattening. Furthermore, depending on the width of the cartons, multiple nuts can be rotated to release the position of the four threaded rods 16 and move the two rectangular plates. 15 drives the two side plates 18 to move, adjusting the distance between the two side plates 18 to meet the side limit of cartons of different widths. The two cylinders 3 operate to drive the mounting plate 4 and the lower pressure plate 7 to move downward. The lower pressure plate 7 moves downward and squeezes the top of the stacked cartons. At the initial contact, the lower pressure plate 7 is buffered by multiple T-shaped rods 5 and multiple first springs 6 to avoid excessive impact. At the same time, the three side plates 18 contact the lower pressure plate 7 and move downward. The three side plates 18 are elastically supported by multiple second springs 17 and move downward under the force of the second springs 17.
