[0002] Cartons are a widely used packaging product, usually made of multi-layer paper, and are mainly used for packaging and transporting items. There are various types of cartons, and cartons can also be designed into different box shapes according to specific needs. During the production process of cartons, the surface of the cartons needs to be laminated with a heated roller to improve the waterproof, moisture-proof and aesthetic properties of the cartons. Therefore, a heated roller device is used in a fully automatic vertical laminating machine for carton production.

[0003] To this end, patent publication number CN220883656U discloses an electromagnetic heating roller for a fully automatic laminating machine, comprising a connecting shaft and a heat-conducting tube. The connecting shaft extends through the heat-conducting tube, and a disassembly assembly is sheathed around the outer periphery of the connecting shaft for easy assembly and disassembly. The disassembly assembly includes the connecting shaft and an electromagnet core. The electromagnet core is provided with an electromagnetic coil that drives the electromagnet block to generate magnetic force, and the connecting shaft is provided with a heating module that heats the heat-conducting tube. The electromagnet core is connected to a fixed plate on its outer side, and the outer wall of the fixed plate is connected to the electromagnet block. The inner side wall of the heat-conducting tube is provided with a mounting groove, and a second magnet is connected to one side wall of the mounting groove. The electromagnet block and the second magnet cooperate with each other.

[0004] When the electromagnetic heating roller of the fully automatic laminating machine mentioned above is in use, the heat is transferred to the outer roller through the heat-conducting tube, thereby achieving the effect of heat transfer without direct contact between the heat conductor and the heating element. However, it is inconvenient to seal and prevent heat leakage during use, which makes it less suitable for use. Utility Model Content

[0005] The utility model aims to provide a heating roller device for a fully automatic vertical laminating machine for carton production, so as to solve the defect that the heating roller device of the existing fully automatic vertical laminating machine for carton production is inconvenient to seal.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a heating roller device of a fully automatic vertical laminating machine for carton production, comprising a roller body and an end cover;

[0007] End caps are fixed to both ends of the roller body, a connecting shaft is fixed to one side of the end cap, a flange is fixed to one end of the connecting shaft, and reinforcing ribs are evenly fixed on the outer wall of the other end of the connecting shaft;

[0008] A monitoring structure is installed on the inner side of the roller body, and a heating structure is provided inside the roller body;

[0009] The outer sides of the end covers are all provided with sealing structures.

[0010] When using the device, by providing a sealing structure, the device is easy to seal, thereby improving the applicability of the heating roller device of the fully automatic vertical laminating machine for carton production when in use; by providing a heating structure, the device is easy to heat evenly, thereby improving the work efficiency of the heating roller device of the fully automatic vertical laminating machine for carton production when in use; by providing a monitoring structure, the device is easy to monitor in real time, thereby improving the convenience of the heating roller device of the fully automatic vertical laminating machine for carton production when in use.

[0011] Preferably, one side of the reinforcing rib is fixedly connected to one side of the end cap, and the reinforcing ribs are symmetrically distributed at both ends of the roller body. Under the action of the reinforcing ribs, the connection between the connecting shaft and the end cap is prevented from breaking.

[0012] Preferably, the heating structure includes a heat transfer oil chamber, a first connecting hole, an oil inlet pipe, an oil drain pipe, and a second connecting hole. The heat transfer oil chamber is disposed within the roller body. The first connecting hole is disposed at the top of the roller body on one side of the heat transfer oil chamber, and the second connecting hole is disposed at the bottom of the roller body on the other side of the heat transfer oil chamber. The oil inlet pipe is fixed to the outer wall of the roller body at the end of the first connecting hole away from the heat transfer oil chamber, and the oil drain pipe is fixed to the outer wall of the roller body at the end of the second connecting hole away from the heat transfer oil chamber. An oil pump is connected to one end of the oil inlet pipe, and the oil inlet valve is opened to allow hot oil to enter the heat transfer oil chamber through the first connecting hole. The oil inlet valve is then closed. Under the action of the heat transfer oil chamber, efficient and uniform heating is ensured.

When the heating lamps are connected to a power source, they heat the inner side of the roller, allowing the heat to pass through the roller and heat the carton. The temperature sensor monitors the temperature inside the roller. When the temperature reaches a preset value, the temperature sensor controls the heating lamps via a single-chip microcomputer to stop heating, preventing damage to the carton caused by excessive temperature.

[0020] By providing a monitoring structure, the heating lamp is prevented from contacting the inner side of the roller body under the support of the fixed plate. When the heating lamp is connected to a power source, the heating lamp will heat the inner side of the roller body, and the heat will pass through the roller body to heat the carton. The temperature sensor will monitor the temperature of the inner side of the roller body. When the temperature reaches the preset value, the temperature sensor will control the heating lamp to stop heating through the single-chip microcomputer, so as to avoid damage to the carton caused by excessive temperature.
