Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, specifically a corrugated cardboard rolling mill. Background Technology

[0002] The corrugated board rolling mill is one of the key pieces of equipment in the corrugated board production line. Its main function is to roll the pressed corrugated board to improve its flatness and quality. During the rolling process, the corrugated board will pass through one or more pairs of rotating center rollers and pressure rollers. The rolling process removes air bubbles from the corrugated board and makes its surface smoother.

[0003] To improve the quality of corrugated cardboard after being crushed by a rolling mill, existing technologies have made many improvements to the corrugated cardboard rolling mill. For example, patent publication number CN220390496U discloses a corrugated cardboard rolling mill, which includes a processing box. The processing box has a feed inlet on one side and a discharge outlet on the other side. A support plate is fixedly connected to the lower end of the processing box near the discharge outlet. The upper end of the support plate is fixedly connected to the front and rear sides of the support plate, respectively. The telescopic ends of the two first electric telescopic rods are fixedly connected to the same shovel plate. This utility model, by setting up a support plate, first electric telescopic rods, and shovel plate, facilitates the removal of corrugated cardboard from the circulating conveyor belt after crushing. This avoids the phenomenon that the corrugated cardboard sticks to the circulating conveyor belt due to excessive pressure during the crushing process, making it difficult to remove later.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes how a pressure cylinder presses several layers of corrugated cardboard coated with glue to achieve the effect of bonding multiple layers of corrugated cardboard. However, in actual operation, the bonding process with glue requires a certain amount of time. In the aforementioned comparative document, the contact area between the pressure cylinder and the corrugated cardboard is limited. When the corrugated cardboard slides past the pressure cylinder, the glue may not have set yet, causing the corrugated cardboard to detach from the bond after the pressure cylinder has pressed it over. This reduces the effectiveness of the pressing and bonding process. Therefore, there is an urgent need in the art to improve the corrugated cardboard pressing machine to overcome the shortcomings of the existing technology. Utility Model Content

A second drive unit 10 for driving the two pressing and crushing belts 5 to move towards or away from each other is provided on the upper part of the housing 1.

[0032] Specifically, when corrugated cardboard needs to be pressed and bonded, two layers of corrugated cardboard panels are guided by guide rollers 2 to the space between two heating rollers 4. At the same time, a layer of corrugated core board is passed between two corrugated rollers 3 and guided to the space between two heating rollers 4. The two corrugated rollers 3 corrugate the corrugated core board. The heating rollers 4 are existing technologies that can heat the corrugated cardboard. The three layers of corrugated cardboard are coated with glue and heated by the heating rollers 4. The heated corrugated cardboard moves between two pressing and rolling belts 5. The first driving unit 9 drives two symmetrical driving rollers 8 to rotate in opposite directions. The driving rollers 8 drive the two pressing and rolling belts 5 to drive and press the bonded corrugated cardboard. The corrugated cardboard is kept in a pressed state for a period of time so that the glue can fully play its bonding role and improve the quality of the corrugated cardboard after bonding and pressing.

[0033] As a technical optimization of this utility model, the first drive unit 9 includes a first drive motor 11 disposed on one side of the housing 1. A second moving groove 12 adapted to the drive roller 8 is opened on one side of the housing 1. A first limiting block 17 adapted to the second moving groove 12 is rotatably connected to the side of the drive roller 8. A first mounting plate 13 for mounting the first drive motor 11 is fixedly connected to the side of one of the first limiting blocks 17.

A first transmission belt 16 for transmission is sleeved between the sides of the two first transmission wheels 15.

[0034] Specifically, when it is necessary to drive the two drive rollers 8, the first drive motor 11 is started. The output end of the first drive motor 11 drives one of the first gears 14 and one of the first transmission wheels 15 to rotate. The first gear 14 drives the other first gear 14 to rotate. The first gear 14 drives the upper drive roller 8 to rotate. The first transmission wheel 15 drives the other first transmission wheel 15 to rotate through the first transmission belt 16. The first transmission wheel 15 drives the lower drive roller 8 to rotate. The two drive rollers 8 rotate in opposite directions, thereby enabling the two pressing and rolling belts 5 to be driven simultaneously and synchronously, so as to press and roll the corrugated cardboard at the same time.

[0035] As a technical optimization of this utility model, the first limiting block 17 is fixedly connected to the abutting side of the second limiting block 18, and the opposite side walls of the second moving groove 12 are provided with the third moving groove 19 adapted to the second limiting block 18. The first mounting plate 13 is fixedly connected to the second mounting plate 20, and the second mounting plate 20 is threaded through and connected with the adjusting bolt 21.

The first mounting plate 13 is provided with the limiting groove 25 adapted to the fixing frame 22, and the adjusting bolt 21 is threadedly connected to the side of the limiting nut 24.

[0036] Specifically, when it is necessary to crush corrugated cardboard of different thicknesses, the distance between the two pressing and crushing belts 5 is adjusted by the second drive unit 10. At this time, the fixed plate 7 slides in the first moving groove 6, the first limiting block 17 slides in the second moving groove 12, and the second limiting block 18 slides in the third moving groove 19 to limit the position of the fixed plate 7. After the distance between the two drive rollers 8 is adjusted, the first transmission belt 16 needs to be tensioned. By rotating the adjusting bolt 21, the adjusting bolt 21 drives the fixed frame 22 to slide in the limiting groove 25. The fixed frame 22 drives the tensioning wheel 23 to tension the first transmission belt 16. Then, the limiting nut 24 is tightened to limit and fix the position of the adjusting bolt 21, so that when crushing corrugated cardboard of different thicknesses, both pressing and crushing belts 5 can be driven synchronously.

[0037] As a technical optimization of this utility model, the second drive unit 10 includes a second drive motor 26 fixedly installed on the upper part of the housing 1, a third limiting block 27 fixedly installed on one side of the fixing plate 7, a fourth moving groove 28 adapted to the third limiting block 27 is opened on the inner side wall of the first moving groove 6, a lead screw 29 extending to the upper part of the housing 1 is rotatably connected in the fourth moving groove 28, the lead screw 29 passes through the third limiting block 27 and is threadedly connected to the third limiting block 27, the upper end of one lead screw 29 is fixedly connected to the output end of the second drive motor 26, a second transmission wheel 30 is fixedly installed on the upper side of the lead screw 29, and a second transmission belt 31 for transmission is sleeved between the sides of the two second transmission wheels 30.

[0038] Specifically, when it is necessary to adjust the distance between the two pressing and rolling belts 5, the second drive motor 26 is started. The output end of the second drive motor 26 drives one of the second transmission wheels 30 to rotate. This second transmission wheel 30 drives the other second transmission wheel 30 to rotate through the second transmission belt 31. The second transmission wheel 30 drives the lead screw 29 to rotate. When the lead screw 29 rotates, the third limiting block 27 slides in the fourth moving groove 28. The threads of the lead screw 29 are symmetrical and opposite in direction. Therefore, when the lead screw 29 rotates, it drives the two third limiting blocks 27 to move in opposite directions or towards each other, thereby achieving the effect of adjusting the distance between the two pressing and rolling belts 5 and improving the applicability of the overall cardboard rolling device.

[0039] As a technical optimization of this utility model, a number of glue frames 32 and collection frames 38 are fixedly installed between the inner side walls of the box 1. A number of glue-applying rollers 33 and glue-spreading rollers 34 adapted to the glue frames 32 are rotatably connected between the inner side walls of the box 1. A glue box 35 is provided on one side of the box 1. The glue box 35 is provided with a glue outlet pipe 36 and a collection pipe 37 adapted to the glue frames 32 and the collection frames 38, respectively.

[0040] Specifically, when applying glue to three-layer corrugated cardboard, the glue is pumped from the glue tank 35 to the glue frame 32 via the glue outlet pipe 36. The third drive motor 40 is started, and its output drives one of the third transmission wheels 41 to rotate. This third transmission wheel 41 drives the other third transmission wheel 41 to rotate via the third transmission belt 42. The two third transmission wheels 41 drive the glue application roller 33 and the even glue roller 34 to rotate respectively. The glue application roller 33 is in contact with one side of the cardboard. When the glue application roller 33 rotates, its surface is covered with glue, and the even glue roller 34 rotates to smooth the glue on the surface of the glue application roller 33. Then, the glue application roller 33 applies glue to the corrugated cardboard. After that, the glue application roller 33 passes the scraper 39, which scrapes off the impurities adhering to the glue application roller 33. The impurities fall into the collection frame 38 and are collected into the glue tank 35 through the collection pipe 37. After filtration, the glue can be reused, improving the glue application effect on the corrugated cardboard.

[0044] Specifically, the fifth drive motor 46 is started, and the output end of the fifth drive motor 46 drives one of the third gears 45 to rotate. This third gear 45 drives the other third gear 45 to rotate, and the two third gears 45 drive the two corrugated rollers 3 to rotate in opposite directions, which corrugates the cardboard and also conveys it.
