Description

Technical Field

[0001] The utility model relates to the technical field of steel rollers, in particular to a stainless steel cold water steel roller. Background Art

[0002] The cooling roller is a roller that has cooling water flowing through it. When calendering a film or coating an adhesive tape, in order to reduce the deformation caused by the shrinkage of the hot material when it is cooled when the finished product is rolled, the material is passed through the cooling roller to cool it down before rolling to reduce the deformation of the material. The traditional cooling roller is hollow inside, so when the cooling water is passed through, the cooling water fills the entire cooling roller, resulting in a large weight of the cooling roller, which leads to a large load on the bracket used to support the cooling roller and the motor that drives it to rotate. At the same time, since the cooling water flows in the cooling roller for a long time, it is easy to cause scale to form on the inner wall of the cooling roller. The cleaning of the traditional cooling roller is particularly inconvenient, and the accumulated scale will reduce the cooling effect of the cooling roller. Utility Model Content

[0003] The utility model aims to provide a stainless steel cold water steel roller, which is used to overcome the above-mentioned defects in the prior art.

[0004] According to the utility model, a stainless steel cold water steel roller comprises a roller body, an inner tube is arranged in the roller body, a cleaning seat is fixed to the left end of the inner tube, a roller cover is fixed to the right end of the inner tube, two left-right symmetrical water-passing plates are fixed in the inner tube, support tubes are fixed in the left end surface of the roller body and in the right end surface of the roller cover, a connecting tube is fixed to the end surface of one side of the support tube close to the corresponding side of each water-passing plate, and a circumferentially distributed water-passing cavity is provided in each water-passing plate.

[0005] Furthermore, a cavity opening to the right is provided in the roller body, and the outer periphery of the cleaning seat abuts against the inner wall of the cavity. The cleaning seat moves along the inner wall of the cavity, so that scale on the inner wall of the cavity can be scraped off.

[0006] Furthermore, a cylindrical space is formed between the outer periphery of the inner tube and the inner wall of the cavity, and cooling water is poured into the cylindrical space to achieve cooling.

[0007] Furthermore, a fixing ring is fixed inside the cleaning seat, a connecting ring is fixed at the left end of the fixing ring, and the connecting ring can be inserted into the right end of the supporting tube on the left side.

[0008] Furthermore, the left end of the connecting tube on the left side is fixedly connected to the right end of the fixing ring, and the right end of the connecting tube on the right side is fixedly connected to the left end of the supporting tube on the right side.

[0009] Furthermore, one end of the outer side of each water passage cavity is communicated with the cylindrical space outside the inner tube.

[0010] Furthermore, a transition ring is fixed to the left end face of the roller cover, and the outer periphery of the transition ring can abut against the inner wall of the cavity. A sealing ring is fixed on the outer periphery of the transition ring, and the right end face of the sealing ring is fixed to the left end face of the roller cover, and the sealing ring can abut against the right end face of the roller body. The sealing ring and the transition ring can ensure the sealing between the roller cover and the roller body.

[0011] Furthermore, the roller cover is fixed to the right end of the roller body by bolts, and the bolts pass through the sealing ring.

[0012] The beneficial effect of the utility model is that the utility model introduces cooling water into the roller body through the support tube on the left side, the cooling water is injected into the cylindrical space outside the cavity, and the cooling water is discharged from the support tube on the right side. Since the cooling water is reduced to fill the entire cavity, the overall weight of the utility model is reduced compared with the traditional cooling roller, and the load on the support frame and the motor is reduced. At the same time, when it is necessary to clean the scale on the inner wall of the cavity, the inner tube is pulled out of the cavity, and the cleaning seat moves along the inner wall of the cavity, so as to scrape off the scale on the inner wall of the cavity, thereby improving the convenience of cleaning the scale on the inner wall of the cavity.
