Description

Technical Field

[0001] The utility model relates to the technical field of corrugated rollers, in particular to a peripherally heated corrugated roller. Background Art

[0002] Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. The corrugating roller is the most important component of corrugated board production equipment and can heat the paper.

[0003] The existing peripheral heating corrugated roller usually adopts the method of arranging steam channels at equal intervals around the outer ring of the roller. With the help of these equally spaced steam channels, the paperboard in contact with the roller is heated. However, it should be clear that the area occupied by the steam channel is relatively small compared with the entire roller. During the preheating stage, while the steam channel heats the roller surface, a considerable amount of heat will be transferred to the center of the roller shaft by heat conduction. This situation causes the preheating of the roller surface to take a long time. Therefore, it is necessary to design a peripheral heating corrugated roller to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a peripheral heating corrugated roller.

[0012] The utility model has the following beneficial effects:

[0013] 1. The device is equipped with a heating mechanism. When the steam heats the roller near the roller surface, the roller can be heated from the middle of the roller through the electric heating wire, so that the roller as a whole quickly reaches the predetermined temperature. When the equipment is stopped, the power supply can be connected through the electric heating wire, so that the middle of the roller can be kept warm at low temperature, further reducing the subsequent preheating time. At the same time, no large or small steam equipment is required for heat preservation, thereby improving the practicality of the device;

[0014] 2. The device is provided with a fixing mechanism, and by starting the external suction device, the suction force generated at the suction hole enables the paper to be adsorbed on the roller, which is convenient for the subsequent clamping of the paper, thereby improving the practicality of the device.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The side wall of the roller 3 is provided with two fixing mechanisms for fixing the product, the fixing mechanisms include a plurality of suction channels 16 opened on the side wall of the roller 3, a plurality of suction holes 15 connected to the suction channels 16 are opened on the side wall of the roller 3, a plurality of suction pipes 12 are opened on the side wall of the roller 3, and a joint 13 is provided on the suction pipe 12.

[0023] In the utility model, two mounting plates 11 are fixedly connected to the side wall of the roller 3, and two binding ropes 14 are provided on the side wall of the mounting plate 11, so that the suction pipe 12 can be a metal bellows, which is convenient for pulling out the joint 13 and connecting it to the suction equipment pipeline.

[0024] In the present invention, sealing covers 8 are provided at both ends of the installation tube 7, and the sealing covers 8 are threadedly connected to the installation tube 7, so that the electric heating wire 10 can be replaced separately.

[0025] In the utility model, a filter is provided in the air intake hole 15, as shown in the filter diagram, which can prevent dust and paper scraps from clogging the air intake hole 15. The filter is threadedly connected to the air intake hole 15, making it easy to disassemble the filter.

[0026] In the present invention, the binding rope 14 is woven from high temperature resistant fibers, so that the binding rope 14 can be more resistant to high temperatures, and the connector 13 is a quick connector, which facilitates the connection of the connector 13 with the external air suction equipment pipeline.

[0027] In the initial state, the installation pipe 7 is filled with heating oil, and the joint 13 is connected to the external air intake equipment pipeline.
