Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hot pressing wheels, in particular to a novel hot pressing wheel for a high-uniformity film laminating machine. Background Art
[0002] The main function of the hot pressing wheel of the laminating machine in the laminating machine equipment is to provide the necessary pressure and heat during the laminating process to achieve precise forming and processing of thin film materials. When the current passes through the coil of the inductive hot pressing wheel during use, a magnetic field will be generated. This magnetic field will interact with the metal conductor inside the pressing wheel, causing eddy currents to be generated in the conductor. Eddy currents will generate heat inside the conductor, thereby heating the pressing wheel. When the pressing wheel contacts the object to be heated, the heat will be transferred to the surface of the object to achieve the purpose of heating. Therefore, the pressing wheel needs to have a strong heat conduction effect. Most traditional pressing wheels use a pressing wheel that is heated by a resistance heating tube. When this type of pressing wheel is used, there is no heat insulation structure on the outside. When the pressing wheel cooperates with the heat transfer of the pressing film, there are problems of uneven heat transfer and fast heat dissipation on the surface of the pressing wheel, which makes the laminating process not uniformly heat-conducting.
[0003] Therefore, the utility model provides a novel high-uniformity hot pressing wheel for a laminating machine which does not require heat conduction through a heating tube. Utility Model Content

[0006] A novel high uniformity film laminating machine hot pressing wheel comprises a pressing wheel main shaft, two connecting sections respectively arranged at both ends of the pressing wheel main shaft and two connecting flanges respectively matched with the connecting sections to connect with the pressing wheel main shaft, inner sides of both ends of the pressing wheel main shaft are provided with inner embedding openings with a diameter corresponding to the diameter of the plug-in section on the connecting section, and the two connecting sections are plugged into the inner embedding openings through the plug-in section;
[0007] The outer sleeve of the pressure wheel main shaft is provided with an aluminum alloy heat-conducting layer, and the connecting flange is sleeved with the outer wall of the connecting section, and the docking plate on the connecting flange fits with the end of the pressure wheel main shaft to limit the aluminum alloy heat-conducting layer, and the connecting flange is provided with a plug welding hole for welding with the connecting section, and the connecting flange and the connecting section are welded into one through the plug welding hole.
[0008] Furthermore, eight pin holes are correspondingly provided on the outside of the aluminum alloy thermal conductive layer and the pressure wheel main shaft, and positioning pins are respectively inserted in the pin holes. The top ends of the positioning pins are on the same plane as the surface of the aluminum alloy thermal conductive layer. The aluminum alloy thermal conductive layer and the pressure wheel main shaft are defined as a whole by the positioning pins, thereby avoiding problems such as shaking of the aluminum alloy thermal conductive layer when cooperating with the pressure wheel main shaft for film pressing.
[0009] Furthermore, the outer edge of the butt joint plate on the connecting flange is on the same plane as the aluminum alloy heat conducting layer, so as to maintain the neat effect of the aluminum alloy heat conducting layer and the membrane cooperation processing.
[0010] Furthermore, the end of the connecting flange is chamfered at the connection with the connecting section, and the connecting flange is welded and fixed to the connecting section by matching at the chamfer. By welding at the chamfer, the connecting flange and the connecting section are welded into a whole, thereby maintaining the firmness of the connecting flange and the connecting section to fix the aluminum alloy thermal conductive layer.
[0011] Furthermore, the two ends of the pressure wheel main shaft are chamfered at the connection points corresponding to the plug-in section, and the pressure wheel main shaft is fixed to the connection section by welding at the chamfered parts, thereby improving the firmness of the connection between the pressure wheel main shaft and the plug-in section.
[0012] Furthermore, the pressure wheel main shaft, the connecting section, the connecting flange, and the aluminum alloy heat-conducting layer are fixed coaxially.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The new high-uniformity laminating machine hot pressing wheel fixes the aluminum alloy heat-conducting layer through the pressing wheel main shaft, the connecting section and the connecting flange. When the hot pressing wheel is used with the laminating machine, heat conduction does not need to pass through the heating pipe, and has the effect of fast heating speed. When the hot pressing wheel stops heating, the aluminum alloy heat-conducting layer has a high heat conduction effect, and has the advantages of less residual temperature of the heating body and not easy to overheat.
[0015] When the connecting section is energized, electromagnetic induction generates eddy currents inside the pressure wheel main shaft, causing heat to be generated. The heating method can generate heat more evenly on the entire pressure wheel main shaft, and evenly conduct heat to the aluminum alloy heat conductive layer through the pressure wheel main shaft, avoiding local overheating or overcooling of the hot pressure wheel. The precise control system can accurately adjust the power and frequency of the induction heating, thereby achieving a stable and uniform heating effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A novel high uniformity laminator hot pressing wheel comprises a pressing wheel main shaft 1, two connecting sections 2 respectively arranged at both ends of the pressing wheel main shaft 1, and two connecting flanges 3 respectively matched with the connecting sections 2 to connect with the pressing wheel main shaft 1, the inner sides of both ends of the pressing wheel main shaft 1 are provided with inner embedding openings 5 whose diameters correspond to the diameters of the plug-in sections 4 on the connecting sections 2, and the two connecting sections 2 are plugged into the inner embedding openings 5 through the plug-in sections 4;

[0027] Furthermore, eight pin holes 9 are correspondingly provided on the outside of the aluminum alloy thermal conductive layer 6 and the pressure wheel main shaft 1, and positioning pins 10 are respectively inserted in the pin holes 9. The top of the positioning pins 10 is on the same plane as the surface of the aluminum alloy thermal conductive layer 6. The aluminum alloy thermal conductive layer 6 and the pressure wheel main shaft 1 are defined as a whole by the positioning pins 10, thereby avoiding problems such as shaking of the aluminum alloy thermal conductive layer 6 when cooperating with the pressure wheel main shaft 1 to press the film.
[0028] Furthermore, the outer edge of the docking plate 7 on the connecting flange 3 is on the same plane as the aluminum alloy heat-conducting layer 6, so as to maintain the neat effect of the aluminum alloy heat-conducting layer 6 on the film matching processing.
[0029] Furthermore, the end of the connecting flange 3 is chamfered at the connection with the connecting section 2, and the connecting flange 3 is welded and fixed to the connecting section 2 through the chamfer. Through the welding at the chamfer, the connecting flange 3 and the connecting section 2 are welded into a whole, thereby maintaining the firmness of the connecting flange 3 and the connecting section 2 to fix the aluminum alloy thermal conductive layer 6.
[0030] Furthermore, the connection parts of the two ends of the pressure wheel main shaft 1 corresponding to the plug-in section 4 are chamfered, and the pressure wheel main shaft 1 is welded and fixed to the connecting section 2 by welding at the chamfered parts, thereby improving the firmness of the connection between the pressure wheel main shaft 1 and the plug-in section 4.
[0031] Furthermore, the pressure wheel main shaft 1, the connecting section 2, the connecting flange 3, and the aluminum alloy heat-conducting layer 6 are fixed coaxially.
[0032] Compared with the prior art, the beneficial effects of the utility model are:
[0033] The novel high uniformity laminating machine hot pressing wheel fixes the aluminum alloy heat conducting layer 6 by means of the pressing wheel main shaft 1, the connection section 2 and the connection flange 3. When the hot pressing wheel is used with the laminating machine, heat conduction does not need to be conducted through the heating pipe, and has the effect of fast heating speed. When the hot pressing wheel stops heating, the aluminum alloy heat conducting layer 6 has a high heat conduction effect, and has the advantages of less residual temperature of the heating body and not easy to overheat.

[0035] In actual use: when current passes through the inductive hot pressing wheel coil connected to the pressing wheel main shaft 1 and the connecting section 2, a magnetic field will be generated. This magnetic field will interact with the metal conductor inside the pressing wheel, causing eddy currents to be generated in the conductor. The eddy currents will generate heat inside the conductor, thereby heating the pressing wheel. When the pressing wheel contacts the object to be heated, the heat will be transferred to the surface of the object to achieve the purpose of heating.
[0036] The new high uniformity laminating machine hot pressing wheel uses an aluminum alloy heat conductive layer 6 for heat conduction. The thermal conductivity of aluminum in the aluminum alloy heat conductive layer 6 is about 237W / (m·K), while the thermal conductivity of iron is about 80W / (m·K), which means that under the same conditions, heat transfer in aluminum is much faster than in iron.
