Description

Technical Field

[0001] This utility model belongs to the field of heating roller technology, specifically relating to a roller pressing device for bonding sheet metal and skin. Background Technology

[0002] In fields such as furniture manufacturing, automotive interior processing, and home appliance casing production, the bonding process between sheet metal and skin widely adopts heated roller pressing technology. Its core is to transfer heat energy to the contact surface between the sheet metal and skin through heated rollers, while applying roller pressure to achieve a tight bond between the two.

[0003] However, most existing heated roller pressing devices are integral fixed structures, and the width of their heating zone cannot be adjusted according to the actual width of the sheet material and the skin to be bonded. For example, when processing narrow sheet materials with a width of 500mm, if the fixed heating zone width of the heated roller is 1000mm, the excess 500mm heating zone will continuously dissipate heat into the air. Actual measurements show a high rate of heat energy waste, and long-term use will significantly increase production energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a rolling device for bonding sheet metal and skin, which can match the width of the heating zone of the heating roller with the width of the sheet metal and skin, thereby reducing the waste of heat energy during the heating and rolling process of the heating roller on the sheet metal and skin.

[0007] Furthermore, the main heat medium flow zone includes multiple smaller flow zones, which are arranged along the axis of the roller body, and each of the smaller flow zones is connected to the heat medium input group and the heat medium output group.

[0008] Furthermore, the small flow region is a spiral groove.

[0009] Furthermore, a heat-conducting coil is fixedly connected to the outer side of the circular roller.

[0010] Furthermore, the heat-conducting ring is provided with multiple heating zones, each corresponding to a multiple small flow zone, and a heat-insulating ring is embedded and fixedly connected to the inner side of the heat-conducting ring.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-6As shown, a rolling device for bonding sheet metal and skin is essentially a heated roller that can heat and roll the sheet metal and skin. The width of the heating zone of the heated roller can be adjusted so that the width of the heating zone of the heated roller matches the width of the sheet metal and skin.

[0024] Specifically, the rolling device includes a rotating rod 1, with a circular roller 2 fixedly connected to the outer side of the rotating rod 1. A main heat medium flow zone is formed on the circumferential side of the circular roller 2. The main heat medium flow zone is connected to a heat medium input group and a heat medium output group. Heat medium such as heat transfer oil, hot water or steam is input into the main heat medium flow zone through the heat medium input group. After heat exchange on the side wall of the circular roller 2 in the main heat medium flow zone, the heat medium is discharged through the heat medium output group. Thus, the side of the circular roller 2 can be heated by the heat medium. The area on the side wall of the circular roller 2 that is effectively heated by the heat medium is the heating zone. When the circular roller 2 rolls the sheet metal and the skin, the sheet metal and the skin can be heated synchronously.

[0025] The main heat medium flow zone is equipped with an effective flow zone. Both the heat medium input group and the heat medium output group are connected to the effective flow zone. The size of the effective flow zone along the axis of the roller body 2 is adjustable. At this time, by adjusting the size of the effective flow zone along the axis of the roller body 2, the width of the heating zone on the side wall of the roller body 2 that is effectively heated by the heat medium can be adjusted.

[0026] In some embodiments, the main heat medium flow zone is an annular cavity, inside which two slidable annular baffles are installed. The effective flow zone is the space between the two annular baffles. The size of the effective flow zone can be adjusted by moving the annular baffles through a driving component.

[0027] In other implementations, such as Figures 1-3 As shown, the main heat medium flow zone includes multiple smaller flow zones, which are arranged along the axis of the roller body 2. Each of the smaller flow zones is connected to the heat medium input group and the heat medium output group. The heat medium is input into different numbers of smaller flow zones through the heat medium input group. The smaller flow zones with heat medium flowing in them are combined into an effective flow zone, and the width of the effective flow zone can be adjusted.

[0028] The small flow zone can be an annular groove or a spiral groove 7, and preferably a spiral groove 7. The two ends of the spiral groove 7 are connected to the heat medium input group and the heat medium output group respectively, so that the heat medium flows in through one end of the spiral groove 7 and flows out through the other end of the spiral groove 7. The spiral groove 7 guides the heat medium, which can heat the heating area on the side of the roller 2 more evenly.

[0029] like Figures 1-3As shown, a heat-conducting ring 3 is fixedly connected to the outer side of the cylindrical roller 2. The heat-conducting ring 3 is preferably made of copper, which has good thermal conductivity, so that more of the heat energy of the heat medium can be directed to the heat-conducting ring 3 to heat the plate and the skin.

[0030] like Figures 5-6 As shown, the heat-conducting ring 3 is provided with multiple heating zones, which correspond to multiple small flow zones respectively. A heat-insulating ring 11 is embedded and fixedly connected inside the heat-conducting ring 3. The heat-insulating ring 11 is made of heat-insulating material to reduce the heat energy flowing from the inside of the heating zone to the adjacent heating zone.

[0031] like Figures 2-4 As shown, both the heat medium input group and the heat medium output group include a connecting pipe 4. The connecting pipe 4 is connected to a connecting inner pipe 8 through a rotary joint. The connecting inner pipe 8 is fixedly connected inside the rotating rod 1. The connecting inner pipe 8 is connected to multiple connecting branch pipes 9. The multiple connecting branch pipes 9 are respectively connected to multiple small flow areas. A solenoid valve 10 is installed on the connecting branch pipe 9. The solenoid valve 10 is connected to an external control device through a conductive slip ring or other electrical connection equipment. By controlling the multiple solenoid valves 10, it is possible to control whether the multiple small flow areas are connected to the connecting inner pipe 8.

[0032] In some embodiments, the rotary joint includes an annular inner tube 6 fixedly connected to the outside of the rotating rod 1, an annular outer tube 5 rotatably connected to the outside of the annular inner tube 6, the annular outer tube 5 being connected to the connecting pipe 4, and one end of the connecting inner tube 8 being connected to the combination of the annular outer tube 5 and the annular inner tube 6.

[0033] In summary, this technical solution adjusts the width of the heating zone of the circular roller 2 according to the width of the sheet metal and skin, so that the width of the heating zone of the heating roller matches the width of the sheet metal and skin, thereby reducing the waste of heat energy during the heating and rolling process of the heating roller on the sheet metal and skin.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
