Description

Technical Field

[0001] The utility model relates to the technical field of silicone heating rollers, in particular to an embedded silicone heating roller. Background Art

[0002] The embedded silicone heating roller is an industrial heating equipment, usually used in various production processes that require heating, drying or curing. The characteristic of this heating roller is that the heating wire element (usually a resistance wire or other electric heating material) is embedded in the silicone roller body to achieve uniform heat distribution. In addition, silicone has the advantages of small compression permanent deformation, wear resistance, and not easy to age. In addition, the surface energy of silicone is lower than that of most organic materials, so it has low hygroscopicity and can be used in the processing of some wet objects. Silicone does not adhere to many materials and can play an isolation role.

[0003] The interior of the embedded silicone heating roller is a metal roller, and the exterior of the metal roller is a silicone roller. When the silicone roller is worn, damaged, etc. and needs to be replaced, it is not easy to achieve because the silicone roller adheres to the outside of the metal roller. Secondly, the internal heating wire of the silicone roller is embedded in the silicone roller and is in direct contact with the silicone roller. When the heating wire emits an extremely high temperature, it will cause local damage to the silicone roller. Finally, the fixing layer of the silicone roller is not easy to remove and is relatively laborious during disassembly and installation. Therefore, an embedded silicone heating roller is proposed to address the above problems. Summary of the invention

[0004] The purpose of the utility model is to provide an embedded silicone heating roller to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An embedded silicone heating roller comprises a metal roller, a heating layer and a fixed layer, wherein both ends of the metal roller are fixedly connected with a connecting shaft, a heating layer is provided on the outer side of the metal roller, a column is fixedly connected inside the heating layer, a receiving hole is provided inside the column, a silicone tube is rotatably connected inside the accommodating hole, a fixing ring is fixedly connected to the outer side of the silicone tube, a heating wire passes through the silicone tube, a fixing rod is fixedly connected to one end of the outer side of the fixed layer, a fixing groove is provided at the bottom end of the fixing rod, a straight rod is fixedly connected inside the fixing groove, a rotating rod is rotatably connected to the outer side of the straight rod, a locking block is fixedly connected to the other end of the rotating rod, a limiting rod is fixedly connected to the outer side of the rotating rod, a spring is provided on the outer side of the limiting rod, a fixing hole is provided at the other end of the outer side of the fixed layer, a groove is provided on the inner side of the fixed layer, and a protrusion is fixedly connected to the outer side of the heating layer.

[0007] Preferably, the diameter of the heating layer is larger than the diameter of the metal roller, and the heating layer is tightly attached to the outer side of the metal roller.

[0008] Preferably, the fixing layer is in a semicircular ring shape, and the two fixing layers are centrally symmetrically arranged on the outer side of the metal roller.

[0009] Preferably, the size of the fixing rod is smaller than the size of the fixing hole, and the fixing rod can fit inside the fixing hole.

[0010] Preferably, there are a plurality of protrusions, which are arranged at equal intervals on the outside of the heating layer.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by providing the metal roller and the heating layer, the heating layer can be directly sleeved on the outside of the metal roller. When the heating layer needs to be replaced, the fixed layer on the outside of the heating layer is removed, and the heating layer can be directly pulled out from the outside of the metal roller, thereby reducing the difficulty of replacing the heating layer;

[0013] 2. In the utility model, the heating layer, the column, the receiving hole, the silicone tube, the fixing ring and the heating wire are arranged, and the heating wire is fixed in the hollow heating layer through the column, so that the heating wire and the heating layer are not in direct contact, the column provides support and fixing for the heating wire, and the silicone tube is between the heating wire and the column to protect the heating wire;

[0014] 3. In the utility model, the heating layer can be fixed in a limited position by means of the semicircular ring-shaped fixed layer, fixed rod, fixed groove, straight rod, rotating rod, locking block, limiting rod and spring. Moreover, the semicircular ring setting can reduce the difficulty of disassembling the fixed layer. The connection between the fixed layers can be achieved by inserting the rotating rod and the locking block in the fixing rod into the fixing hole, and disassembly does not require the aid of external tools.

A silicone tube 6 rotates in the receiving hole 5. A fixing ring 7 is arranged on the outside of the silicone tube 6. The fixing ring 7 can limit the silicone tube 6 to prevent the silicone tube 6 from escaping from the receiving hole 5. The heating wire 8 passes through the silicone tube 6, and a fixing layer 9 is provided on the outside of the heating layer 3.
