Description

Technical Field

[0001] This application relates to the technical field of corrugated paper production, and in particular to a corrugated roll guide structure. Background Technology

[0002] Currently, in the corrugated paper forming process, steam-heated rollers (specifically including heated cylinders and corrugated rollers on the corrugating line) need to reach a certain temperature in order for the base paper to be preheated by the steam-heated rollers and pressed into corrugated shape, thus producing corrugated cardboard.

[0003] Steam heating is the primary method used for heating the steam-heated rollers. Steam is introduced into the inner cavity of the rollers to raise the temperature of the cylinder and heat the base paper. After heat exchange, the steam condenses into water, which is then discharged from the steam-heated rollers through a siphon to ensure efficient heat exchange.

[0004] However, the following problems exist: 1) Because condensate exists throughout the entire cylinder cavity, and the condensate film is very thin, the siphon tube is a certain distance from the inner cavity surface, making it impossible to draw out the condensate. The condensate film covers the inner surface of the cylinder, forming thermal resistance, reducing the heat exchange between steam and the steam-heated roller, causing the outer surface temperature of the steam-heated roller to drop, resulting in problems such as corrugated cardboard not forming properly and affecting machine speed; 2) When the steam-heated roller stops operating, because there is a certain distance between the siphon tube and the inner surface of the steam-heated roller cavity, the condensate cannot be drawn out and accumulates at the bottom of the steam-heated roller. This causes the steam-heated roller to deform and bend due to the temperature difference between the upper and lower parts, resulting in uneven heating of the base paper; for the corrugated roller in the steam-heated roller, this will lead to the generation of some waste single-wall corrugated paper when restarting. Therefore, to solve the above problems, this application provides a corrugated roller guiding structure. Utility Model Content

[0006] This application provides a corrugated roller guide structure, including a corrugated roller, a bearing sleeved on the shaft tube of the corrugated roller, and an air guide cover installed at its end.

Each branch flow chamber is provided with a branch flow tube, and the branch flow tubes provided in the branch flow chambers corresponding to each main flow chamber are all connected to the same air pipe. The air pipes of each main flow chamber form an air pipe bundle and are connected to an external air extraction structure.

[0007] By setting a guide pipe on the inner side of the corrugated roll and dividing the guide pipe into several main flow chambers for draining condensate, and the branch flow chambers in the main flow chambers can be used for small water flow, the effect of draining condensate inside the corrugated roll can be further improved.

[0008] Preferably, a spacer is provided between adjacent main cavities.

[0020] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0021] Example 1:

[0022] A corrugated roller guide structure, as shown in the reference Figure 1 - Figure 5A bearing 2 is fitted onto the shaft tube 11 of the corrugated roller 1, and an air guide cover 3 is installed at its end. A guide tube 4 is set inside the corrugated roller 1. The interior of the guide tube 4 is divided into several main flow chambers 41, and each main flow chamber 41 is further divided into several branch flow chambers 42. Each branch flow chamber 42 is equipped with a branch flow pipe 61. The branch flow pipes 61 set in the branch flow chambers 42 corresponding to each main flow chamber 41 are all connected to the same air pipe. The air pipes of each main flow chamber 41 form an air pipe bundle 6 and are connected to the external air extraction structure. The air pipes in the main flow chamber 41 are arranged symmetrically along the center line of the guide tube 4. The two air pipe bundles 6 pass out from the fixed pipes 5 at both ends and are connected to the external air extraction structure. Each air pipe is independent of the others to ensure a good water pumping effect.

[0023] By setting a guide pipe 4 on the inner side of the corrugated roller 1 and dividing the guide pipe 4 into several main flow chambers 41 for draining condensate, and the branch chambers 42 in the main flow chambers 41 can be used for small water flow, the effect of draining condensate inside the corrugated roller 1 can be further improved.

[0024] A spacer 7 is provided between adjacent main flow cavities 41.

[0025] A partition 7 is also provided between adjacent diversion chambers 42. The partition 7 is made of rubber and its bottom contacts the inner wall of the corrugated roller 1. The function of the partition 7 is to divide the entire corrugated roller 1 into segments, and further subdivide them. Small streams of water can directly seal the diversion chamber 42, so that when the external air extraction structure is performing air extraction, the water inside the diversion chamber 42 can be smoothly extracted.

[0026] Both ends of the guide tube 4 are provided with fixed tubes 5 that are connected to the outside. The fixed tubes 5 and the two ends of the guide tube 4 are connected by connecting tubes 8. The fixed tubes 5 are used to ensure the overall position of the guide tube 4 is stable, while the connecting tubes 8 provide a channel for the tracheal bundle 6.

[0027] The guide pipe 4 is located at the bottom inner side of the corrugated roller 1. The position of the guide pipe 4 is kept stationary by the fixing pipe 5, and the condensate will eventually collect at the bottom of the corrugated roller 1. Therefore, setting the guide pipe 4 at this position can effectively complete the guiding operation.

[0028] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of a corrugated roller guide structure provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
