Abstract
Description
Technical Field
[0001] This utility model belongs to the field of corrugated cardboard processing technology, specifically relating to a steam-heated roller for corrugated cardboard processing. Background Technology
[0002] Corrugated cardboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of linerboard bonded together. It has good elasticity and extensibility and is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. During the production of corrugated cardboard, the base paper needs to be heated by steam-heated rollers to remove moisture and dry the paper. However, in the use of existing steam-heated rollers, the condensate formed after the internal steam heat exchange mostly adheres directly to the inner surface of the roller body. This is inconvenient to drain and the condensate adhesion also causes temperature differences on the surface of the roller body, thus affecting the heating and drying effect on the base paper. Therefore, to solve the above problems, it is necessary to develop a steam-heated roller for corrugated cardboard processing with a reasonable structural design and good heating effect. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a steam heating roller for corrugated cardboard processing with a reasonable structural design and good heating effect.
[0004] The purpose of this utility model is achieved as follows: A steam-heated roller for corrugated cardboard processing includes an installation assembly, a heating roller, a reinforcing rod, and an air distribution pipe. There are two installation assemblies, symmetrically arranged, each including an installation block and a support rod. The installation block is cylindrical in shape, with an exhaust pipe horizontally fixedly inserted through the upper end of the left installation block, and a pressure valve connected to the exhaust pipe. The support rod is L-shaped, located outside the installation block, with one end concentrically fixed to the installation block and the other end fixedly connected to the corrugated cardboard production line support. The heating roller, made of a heat-conducting material, is located between the two installation assemblies, with its inner surface rotated between the two installation blocks via sealed bearings. The reinforcing rod is horizontally positioned between the two mounting blocks, and a scraper is provided at the lower end of the reinforcing rod. The scraper is inclined, with its upper end fixedly connected to the reinforcing rod and its lower end in close contact with the inner surface of the heating roller. A water collection trough is horizontally provided at one end of the scraper near the inner surface of the heating roller. A drain pipe is fixedly connected to the left end of the water collection trough, and the outer end of the drain pipe passes through the mounting block and is located outside the mounting assembly. The air distribution pipe is annular in shape and is fitted around the outside of the support rod in the right mounting assembly. A steam inlet is connected to the upper end of the air distribution pipe. Multiple air guide pipes are evenly arranged horizontally on one side near the right mounting block. One end of the air guide pipe is fixedly connected to the air distribution pipe, and the other end is located inside the heating roller through the mounting block.
[0005] Furthermore, the end of the scraper that contacts the inner surface of the heating roller is arc-shaped, and the center of the arc structure coincides with the center of the heating roller.
[0006] Furthermore, the bottom surface of the water collection tank has a semi-circular structure.
[0007] Furthermore, the reinforcing rod is a solid rod and is concentrically fixedly connected to the two mounting blocks.
[0008] The beneficial effects of this utility model are as follows: By setting up a reinforcing rod, a scraper, a water collection tank, and a drain pipe, this utility model can achieve a fixed connection between two mounting blocks using the reinforcing rod, thereby increasing the stability of the overall structure of this utility model. The inclined scraper can scrape off the condensate adhering to the inner surface of the heating roller during its rotation. The water collection tank can temporarily store the scraped condensate, and the drain pipe can discharge the condensate temporarily stored in the water collection tank. This utility model adopts this structure, which can solve the problem of temperature differences on the surface of the heating roller caused by the adhesion of condensate, while also increasing the convenience of condensate collection and drainage operations.
[0009] By setting up air distribution pipes and air guide pipes, the uniform distribution of steam inside the heating roller can be achieved through their cooperation, thus avoiding uneven heating of the heating roller. By setting up exhaust pipes and pressure valves, during use, as hot steam is continuously injected, when the air pressure inside the sealed heating chamber formed by the two mounting blocks and the heating roller is greater than the external air pressure, the pressure valve can be opened using the pressure difference, thereby achieving exhaust and pressure relief through the exhaust pipe, improving the safety of this utility model during use. In summary, this utility model has the advantages of reasonable structural design and good heating effect. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] Example: Figure 1 , Figure 2 , Figure 3 As shown, a steam-heated roller for corrugated cardboard processing includes an installation assembly 1, a heating sleeve roller 2, a reinforcing rod 3, and an air distribution pipe 4. There are two installation assemblies 1, symmetrically arranged, each including an installation block 11 and a support rod 12. The installation block 11 is cylindrical, with an exhaust pipe 13 horizontally fixedly inserted through the upper end of the left installation block 11, and a pressure valve 14 connected to the exhaust pipe 13. The support rod 12 is L-shaped, located outside the installation block 11, with one end concentrically fixed to the installation block 11 and the other end fixedly connected to the corrugated cardboard production line support. The heating sleeve roller 2, made of thermally conductive material, is located between the two installation assemblies 1, with its inner surface ends rotatably sleeved with the installation blocks 11 in the two installation assemblies 1 through sealed bearings. The reinforcing rod 3 horizontally... A scraper 5 is provided at the lower end of the reinforcing rod 3, which is located between two mounting blocks 11. The scraper 5 is inclined, with its upper end fixedly connected to the reinforcing rod 3 and its lower end in close contact with the inner surface of the heating roller 2. A water collection trough 51 is provided laterally at one end of the scraper 5 near the inner surface of the heating roller 2. A drain pipe 52 is fixedly connected to the left end of the water collection trough 51, and the outer end of the drain pipe 52 passes through the mounting block 11 and is located outside the mounting assembly 1. The air distribution pipe 4 is annular and is sleeved on the outside of the support rod 12 in the right mounting assembly 1. The upper end of the air distribution pipe 4 is connected to a steam inlet 41. Multiple air guide pipes 42 are evenly arranged laterally on one side near the right mounting block 11. One end of the air guide pipe 42 is fixedly connected to the air distribution pipe 4, and the other end is located inside the heating roller 2 through the mounting block 11.
[0016] The scraper 5 has an arc-shaped end that contacts the inner surface of the heating roller 2, and the center of the arc structure coincides with the center of the heating roller 2; the bottom surface of the water collection tank 51 has a semi-circular structure; the reinforcing rod 3 is a solid rod and is concentrically fixedly connected to the two mounting blocks 11.
[0017] In use, this invention first injects hot steam generated by the steam generator through the steam inlet 41 into the sealed heating chamber formed by the two mounting blocks 11 and the heating roller 2 via the air distribution pipe 4 and the air guide pipe 42. During this process, the air distribution pipe 4 and the air guide pipe 42 ensure uniform steam distribution inside the heating roller 2, preventing uneven heating. Then, the hot steam injected into the sealed heating chamber contacts the inner surface of the heating roller 2, causing heat exchange and condensation while simultaneously heating the roller 2. Next, the paper to be dried is wound around the outside of the heating roller 2, and a driving traction device moves the paper. The contact between the paper and the outer surface of the heating roller 2 allows for heating, drying, and dehumidification of the paper. Simultaneously, the friction between the paper and the heating roller 2 during movement, combined with the rotational connection between the heating roller 2 and the mounting blocks 11, ensures that the paper is heated while the roller is moving. The heating roller 2 is rotated, and during this rotation, the scraper 5, in close contact with its inner surface, scrapes away the condensate adhering to the inner surface of the heating roller 2, preventing temperature differences on the surface of the heating roller 2 due to the condensate. The condensate scraped away by the scraper 5 flows into the water collection tank 51 and is temporarily stored there. It is then discharged to the outside of the invention through the drain pipe 52, which is fixedly connected to the water collection tank 51. This structure increases the convenience of condensate collection and discharge. Furthermore, by setting up the exhaust pipe 13 and pressure valve 14, during use, as hot steam is continuously injected, when the air pressure inside the sealed heating chamber formed by the two mounting blocks 11 and the heating roller 2 is greater than the external air pressure, the pressure valve 14 can be opened using the pressure difference, thereby achieving venting and pressure relief through the exhaust pipe 13, improving the safety of the invention during use. In summary, this invention has the advantages of reasonable structural design and good heating effect.
