Description

Technical Field

[0001] This utility model relates to the field of heating oil roller technology, specifically a heating oil roller for corrugated cardboard production. Background Technology

[0002] Corrugated cardboard is a type of board material consisting of a corrugated core layer and a cover layer formed between two or more layers of cardboard. It is commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", or "corrugated base paper".

[0003] Application number CN213223090U discloses a heating oil roller for corrugated cardboard production, including a roller shaft, bearings, an oil roller, and an air extraction mechanism. This utility model provides a heating oil roller for corrugated cardboard production. A temporary air passage is formed between the oil roller's outer surface grooves and the linerboard. Bernoulli's principle is used to achieve segmented tensioning of the linerboard attaching oil roller. Furthermore, the pipeline design ensures that the air is fully preheated before entering the grooves, guaranteeing the heating effect of the oil roller while significantly increasing the allowable throughput speed of the material during the heating process. However, in practical applications, this application suffers from uneven heating and low thermal efficiency, leading to unstable cardboard quality. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A heating oil roller for corrugated cardboard production includes a heating mechanism. The heating mechanism includes a rotating shaft, a partition cylinder and a heat-conducting roller sleeved on the outside of the rotating shaft, an oil cavity formed between the partition cylinder and the heat-conducting roller, six oil inlet pipes and two oil outlet pipes connected between the rotating shaft and the heat-conducting roller, and two oil grooves opened at both ends of the rotating shaft. The partition cylinder extends laterally through the heat-conducting roller. The multiple oil inlet pipes are all close to one end of the rotating shaft, and the two oil outlet pipes are all close to the other end of the rotating shaft. The bodies of the oil inlet pipes and the oil outlet pipes all extend through the partition cylinder, and the two ends of the oil inlet pipes and the two ends of the oil outlet pipes are respectively connected to the inside of the oil cavity and the inside of the two oil grooves.

[0007] By adopting the above technical solution, hot oil is injected from the right end of the rotating shaft, and then the hot oil is injected into the oil cavity through the oil inlet pipe. Since the number of oil inlet pipes is three times that of the oil outlet pipes, the oil cavity is quickly filled with hot oil. Then the hot oil evenly heats the heat-conducting roller in the oil cavity, achieving high thermal efficiency and ensuring the stability of the paperboard quality.

[0008] In a preferred embodiment, the present invention can be further configured such that: two sets of sealing mechanisms are provided between the partition cylinder and the heat-conducting roller, and each set of sealing mechanisms includes a fluororubber ring that is interference-fitted to the outside of the partition cylinder, a metal expansion ring that is fitted to the outside of the fluororubber ring, and a graphite packing that is fitted to the outside of the metal expansion ring, wherein the graphite packing is embedded at the outer end of the heat-conducting roller.

[0009] In a preferred embodiment, this utility model can be further configured as follows: multiple oil inlet pipes are spaced equally and arranged in a ring around the outside of the rotating shaft, wherein the diameter of the oil inlet pipes is equal to the diameter of the oil outlet pipes.

[0010] In a preferred embodiment, the present invention can be further configured such that flanges are welded to both ends of the rotating shaft.

[0011] In a preferred embodiment, the present invention can be further configured such that: an infrared thermal imager is provided on the top of the heat-conducting roller, and the infrared thermal imager is electrically connected to an external PLC.

[0012] In a preferred embodiment, the present invention can be further configured such that: a plurality of heat-conducting columns surround the outer side of the rotating shaft, the plurality of heat-conducting columns are all located inside the partition cylinder, and the outer ends of the heat-conducting columns pass through the outer wall of the partition cylinder and are in contact with the inner wall of the heat-conducting roller.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, hot oil is injected from the right end of the rotating shaft, and then the hot oil is injected into the oil cavity through the oil inlet pipe. Since the number of oil inlet pipes is three times that of oil outlet pipes, the oil cavity is quickly filled with hot oil. Then the hot oil evenly heats the heat-conducting roller in the oil cavity, achieving high thermal efficiency and ensuring the stability of the paperboard quality.

[0015] 2. In this utility model, while the hot oil heats the heat-conducting roller, it also heats the inside of the partition cylinder through multiple heat-conducting columns. By collecting the residual heat of the hot oil, a heat-insulating layer is formed inside the partition cylinder, reducing energy consumption and achieving environmental protection.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a heating oil roller for corrugated cardboard production.

[0029] Example 1:

[0030] Combination Figure 1-4 As shown, the present invention provides a heating oil roller for corrugated cardboard production, comprising a heating mechanism 100. The heating mechanism 100 includes a rotating shaft 110, a partition cylinder 120 and a heat-conducting roller 130 sleeved on the outside of the rotating shaft 110, an oil cavity 140 formed between the partition cylinder 120 and the heat-conducting roller 130, six oil inlet pipes 150 and two oil outlet pipes 160 connected between the rotating shaft 110 and the heat-conducting roller 130, and two oil grooves 170 opened at both ends of the rotating shaft 110. The partition cylinder 120 extends laterally through the heat-conducting roller 130. The multiple oil inlet pipes 150 are all close to one end of the rotating shaft 110, and the two oil outlet pipes 160 are all close to the other end of the rotating shaft 110. The bodies of the oil inlet pipes 150 and the oil outlet pipes 160 both extend through the partition cylinder 120, and the two ends of the oil inlet pipes 150 and the two ends of the oil outlet pipes 160 are respectively connected to the inside of the oil cavity 140 and the inside of the two oil grooves 170.

[0031] Furthermore, multiple oil inlet pipes 150 are spaced at equal intervals and arranged in a ring around the outside of the rotating shaft 110. The diameter of the oil inlet pipe 150 is equal to the diameter of the oil outlet pipe 160. The layout design of multiple oil inlet pipes 150 can quickly fill the oil cavity 140.

[0032] Furthermore, an infrared thermal imager 400 is provided on the top of the heat-conducting roller 130. The infrared thermal imager 400 is electrically connected to an external PLC. By scanning the surface of the heat-conducting roller 130, the infrared thermal imager 400 can clearly detect the temperature of every inch of the heat-conducting roller 130. The detection information is then transmitted to the external PLC to help technicians understand the temperature rise of the heat-conducting roller 130.

[0033] Furthermore, the outer side of the rotating shaft 110 is surrounded by multiple heat-conducting columns 500, all of which are located inside the partition cylinder 120. The outer ends of the heat-conducting columns 500 pass through the outer wall of the partition cylinder 120 and are attached to the inner wall of the heat-conducting roller 130. The heat-conducting columns 500 are provided to facilitate the collection of residual heat from hot oil.

[0034] Example 2:

[0035] Combination Figure 1-4 As shown, based on Embodiment 1, two sets of sealing mechanisms 200 are provided between the partition cylinder 120 and the heat-conducting roller 130. Both sets of sealing mechanisms 200 include a fluororubber ring 210 that is interference-fitted to the outside of the partition cylinder 120, a metal expansion ring 220 that is fitted to the outside of the fluororubber ring 210, and a graphite packing 230 that is fitted to the outside of the metal expansion ring 220. The graphite packing 230 is embedded at the outer end of the heat-conducting roller 130. The three-layer combined sealing structure greatly improves the sealing performance between the heat-conducting roller 130 and the partition cylinder 120, preventing hot oil leakage.

[0036] Example 3:

[0037] Combination Figure 1-2 As shown, in the above embodiment, flanges 300 are welded to both ends of the rotating shaft 110. The flanges 300 can be used to tightly connect the rotating shaft 110 to external equipment.

[0038] The working principle and usage process of this utility model are as follows: When this device is put into actual use, hot oil is injected from the right end of the rotating shaft 110. Then, the hot oil is injected into the oil chamber 140 through the oil inlet pipe 150. Since the number of oil inlet pipes 150 is three times that of the oil outlet pipes 160, the oil chamber 140 is quickly filled with hot oil. The hot oil then evenly heats the heat-conducting roller 130 in the oil chamber 140, achieving high thermal efficiency and ensuring the stability of the cardboard quality. While the hot oil heats the heat-conducting roller 130, it also heats the inside of the partition cylinder 120 through multiple heat-conducting columns 500. By collecting the residual heat of the hot oil, an insulation layer is formed inside the partition cylinder 120, reducing energy consumption and achieving environmental protection.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
