Description

Technical Field

[0001] This invention relates to the technical field of corrugated paper production, and in particular to a non-stop, rapid switching and maintenance structure for the upper corrugated roll. Background Technology

[0002] Corrugated cardboard is made by bonding together linerboard, core paper, and corrugated paper that has been processed into a wave shape. Depending on the packaging requirements, corrugated cardboard can be processed into single-faced corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer, and other types of corrugated cardboard.

[0003] Existing corrugated machines require roller replacement and maintenance during use. However, due to the large size of the corrugated rollers, replacement is inconvenient and requires machine shutdown, which seriously affects production efficiency. Summary of the Invention

[0012] Furthermore, both the first motor and the third motor are servo stepper motors.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: When corrugated roll maintenance is required, the roll changing device is started, which drives the mounting plate and the upper corrugated roll to rise, so that the bottom upper corrugated roll is away from the lower pressure roll. At the same time, the roll changing device drives the mounting plate and the upper corrugated roll connection to rotate, so that the upper corrugated roll that needs maintenance is rotated to the bottom. Then, the roll changing device drives the mounting plate and the upper corrugated roll connection to fall down until the upper corrugated roll that needs maintenance is pressed on the lower pressure roll. At this time, the upper corrugated roll that needs maintenance is located above, which facilitates the non-stop switching maintenance of the upper corrugated roll. Attached Figure Description

A second mounting groove 4 is provided through the first vertical plate 1, and a first mounting groove 3 is provided through the second vertical plate 2. First mounting shafts 7 are provided on both sides of the three sets of upper corrugated rollers 6, and the three sets of upper corrugated rollers 6 are rotatably mounted between the two sets of mounting plates 5 by means of the first mounting shafts 7, with the axes of the three sets of upper corrugated rollers 6 being parallel.

The power device 9 is mounted on the left mounting plate 5 and is used to drive the three sets of upper corrugated rollers 6 to rotate along their own axes.

[0024] In this embodiment, when corrugated roll maintenance is required, the roll changing device 8 is activated, causing the mounting plate 5 and the upper corrugated roll 6 to rise, so that the bottom upper corrugated roll 6 is away from the lower pressure roll.
