Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper sizing equipment, and more specifically, to a tipping device for a sizing machine. Background Technology

[0002] During the production of corrugated paper, the paperboard is usually conveyed to a sizing machine, where it is glued by the corrugating rollers and gluing rollers. For example, Chinese patent document CN214717895U discloses a high-precision sizing gap adjustment device for a corrugated machine, which includes a frame, corrugating rollers, and a sizing assembly. The corrugating rollers are mounted on the frame, and the sizing assembly is oscillatingly connected to the frame via a fulcrum. A sizing roller is located next to the corrugating roller on the sizing assembly. An inclined surface adjustment mechanism is provided between the frame and the sizing assembly. The inclined surface adjustment mechanism includes an inclined block mounted on the frame and moving up and down, and a slider mounted on the sizing assembly via a fixed base assembly. The slider engages with the inclined surface of the inclined block.

[0003] Although the existing sizing machine can adjust the gap between the sizing roller and the corrugated roller through the inclined plane adjustment mechanism, the structure of the inclined plane adjustment mechanism is relatively complex, the equipment cost is high, and the maintenance difficulty is relatively high. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a tipping device for a sizing machine to solve the problems in the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a tipping device for a sizing machine, including two sizing side plates and a machine body, a corrugated roller is installed on the machine body, the sizing side plates are swayably installed on the machine body, a sizing roller is provided on the sizing side plates, and an eccentric shaft adjustment part is provided between the sizing side plates and the machine body. When the sizing roller is close to the corrugated roller, the eccentric shaft adjustment part is used to limit the downward swing stroke of the sizing side plates.

[0006] In the aforementioned tipping device of a sizing machine, the eccentric shaft adjustment part includes a positioning wheel and an eccentric shaft. The positioning wheel is mounted on the sizing side plate, and the eccentric shaft is rotatably mounted on the machine body. The sizing side plate swings downward so that the positioning wheel contacts the eccentric shaft.

[0007] In the aforementioned tipping device of a sizing machine, the lower ends of the two sizing side plates are rotatably mounted on the lower end of the machine body via hinge shafts.

[0008] In the aforementioned tipping device of a sizing machine, a hydraulic cylinder is connected to the upper end of the sizing side plate, the cylinder body of the hydraulic cylinder is hinged to the machine body, and the output shaft of the hydraulic cylinder is hinged to the sizing side plate.

[0009] In the tipping device of the aforementioned sizing machine, guide wheels are installed on the lower end of the two sizing side plates away from the hinge axis.

[0010] The beneficial effects of this utility model are that, during the gluing process, the sizing roller can swing downwards by being driven by the sizing side plate, and the downward swing stroke of the sizing side plate can be adjusted by the eccentric shaft adjustment part, thereby adjusting the gap between the sizing roller and the corrugated roller. The entire structure is simpler than the prior art, the equipment cost is relatively lower, and the maintenance difficulty is lower. Attached Figure Description

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0015] Combination Figure 1 and Figure 2 The tipping device of the sizing machine shown includes two sizing side plates 1 and a machine body 8. A corrugated roller 9 is installed on the machine body 8. The sizing side plates 1 are swayably installed on the machine body 8. A sizing roller 5 is provided on the sizing side plates 1. An eccentric shaft adjustment part is provided between the sizing side plates 1 and the machine body 8. When the sizing roller 5 is close to the corrugated roller 9, the eccentric shaft adjustment part is used to limit the downward swing stroke of the sizing side plates 1. In this embodiment, when applying glue, the sizing roller 5 can swing downward by being driven by the sizing side plates 1. At the same time, the downward swing stroke of the sizing side plates 1 is adjusted by the eccentric shaft adjustment part, thereby adjusting the gap between the sizing roller 5 and the corrugated roller 9. The entire structure is simpler than the prior art, the equipment cost is relatively lower, and the maintenance difficulty is lower.

[0016] Specifically, the eccentric shaft adjustment unit in this embodiment includes a positioning wheel 6 and an eccentric shaft 7. The positioning wheel 6 is mounted on the sizing side plate 1, and the eccentric shaft 7 is rotatably mounted on the machine body 8. The sizing side plate 1 swings downward, causing the positioning wheel 6 to contact the eccentric shaft 7. By rotating the eccentric shaft 7, the sizing side plate 1 swings downward, thereby adjusting the swing amplitude of the sizing side plate 1, thereby changing the gap between the sizing roller 5 and the corrugated roller 9. Even after the positioning wheel 6 contacts and presses against the eccentric shaft 7, the gap between the sizing roller 5 and the corrugated roller 9 can be adjusted in real time by rotating the eccentric shaft 7. This makes it more convenient to use, has a simpler structure, and higher adjustment accuracy.

[0017] In some embodiments, a servo motor mounted on the body 8 is provided at one end of the eccentric shaft 7. The servo motor drives the eccentric shaft 7 to rotate, so as to adjust the rotation angle of the eccentric shaft 7. In other embodiments, the eccentric shaft 7 can also be rotated manually, for example, by using a handwheel. By installing a handwheel at one end of the eccentric shaft 7, the angle of the eccentric shaft 7 can be adjusted by rotating the handwheel. The driving components and connection structures of these eccentric shaft 7 are all prior art, and those skilled in the art should understand them, so they will not be described in detail here.

[0018] It is worth noting that, in this embodiment, the lower end of the sizing side plate 1 on both sides is rotatably mounted on the lower end of the machine body 8 via the hinge shaft 2; so that the sizing side plate 1 can move by flipping and swinging, so that the sizing roller 5 approaches the corrugated roller 9 for gluing. During the gluing process, under the gravity of the hinge point and the sizing side plate 1, the entire sizing side plate 1 will not shift, so that the gap between the sizing roller 5 and the corrugated roller 9 remains unchanged, making the gluing process more stable.

[0019] In order to facilitate the swinging of the sizing side plate 1, a hydraulic cylinder 4 is connected to the upper end of the sizing side plate 1. The cylinder body of the hydraulic cylinder 4 is hinged to the machine body 8, and the output shaft of the hydraulic cylinder 4 is hinged to the sizing side plate 1. The output shaft of the hydraulic cylinder is hinged to the sizing side plate 1 diagonally opposite the hinge shaft 2. By pulling the sizing side plate 1 with the hydraulic cylinder 4, the sizing side plate 1 can be driven to swing around the hinge shaft 2.

[0020] In this embodiment, guide wheels 3 are installed on the lower end of the two sizing side plates 1 away from the hinge shaft 2. Under the action of the guide wheels 3, the sizing side plates 1 can be easily dragged when disassembling for maintenance, reducing labor intensity.

[0021] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
