Description

Technical Field

[0001] The invention relates to a high-temperature hot molding roller technology, in particular to a high-temperature hot molding roller. Background Art

[0002] Today, the demand for robots, clean rooms and 5G equipment is gradually increasing in many aspects such as industrial manufacturing capacity upgrades, industry upgrades, and Industry 4.0. Among them, electricity and communications are the blood of industrial manufacturing, and wires and cables are its blood vessels and nerves. How to make wires and cables work smoothly in various harsh environments has always been a problem that plagued the traditional drag chain and traditional cable sheathing industry. The emergence of new dust-free drag chain technology has solved this problem, such as Figure 4The dust-free cable (Pod) assembly shown in the figure adopts a flat structure, which greatly reduces the installation height of the drag chain and increases the service life of the cables and other components inside the drag chain. The Pod is made of a composite of high molecular PU (polyurethane) and e-PTFE (microporous polytetrafluoroethylene formed by stretching), and has the characteristics of high cleanliness, self-cleaning, resistance to tortuosity, and fatigue resistance. Its support chain adopts modified PA, with precise angles and a firm structure. Its built-in filling components include highly flexible cables and air pipes. The highly flexible cables are wound in a combination of e-PTFE and shielded wire to improve the stability of signal transmission. The key to making such a dust-free drag chain or cable sheath is to compound the two layers of PU / e-PTFE again. At this time, a special high-temperature hot molding roller is required for hot pressing and molding. However, due to the material properties of PTFE and PU, this pressing must be done at a high temperature of about 250°C. The heating methods in the prior art have more or less problems: (1) Electric heating (1) The electromagnetic heating roller has the advantages of simple structure, and the cable can be quickly disconnected through the collector ring, but its service life is unstable, power consumption is high, and temperature control is difficult; (2) Oil heating has the advantages of good temperature uniformity, but it is not conducive to frequent disassembly, high energy consumption, inconvenient maintenance, and the risk of oil leakage, which causes oil pollution on site. In addition, the equipment structure is complex, and the external mold temperature controller causes equipment delays and is not friendly to site cleanliness; (3) Although the electromagnetic heating roller has precise temperature control and convenient roller power and signal disconnection, it is very suitable for the required roller requirements, but its own weight is too large, it is difficult for a single person to operate and replace, and the unit price is high. Later maintenance is difficult, and maintenance requires special equipment and personnel. The cost is too high, which is not conducive to large-scale application; (4) Infrared heating has the advantages of simple structure, high heating efficiency, energy saving, and rapid temperature response, but its heating method is mostly an external heating lampshade, which has relative requirements for equipment space, and it is difficult to adjust the temperature uniformity. Due to the external structure, its protection requirements are high, which is not conducive to frequent disassembly and replacement of rollers. Therefore, which heating mode to use has always been a problem that troubles the industry. In addition, there are many types of cable sheaths or dust-free drag chains, and the combination of various power cables, communication wires, and pneumatic air pipes, resulting in a wide variety of product specifications. If one device produces a product of one specification, the number of heat pressing devices required will be difficult to count, and it will be extremely unfriendly to energy consumption and production costs. In addition, new dust-free drag chains or cable sheaths have strict requirements on the production site and require a factory with a certain degree of cleanliness. Therefore, if one device is used for one specification, it is extremely unfavorable for large-scale production.

[0003] Adopting a quick-replacement pressure roller is one way to solve the above problems. However, on the one hand, it is still difficult to quickly disassemble and assemble the pressure roller in the heating mode. On the other hand, in terms of mechanical structure, the roller is traditionally fixed with bearings on both sides, which ensures the installation accuracy of the roller, but also makes it difficult to disassemble and replace the roller. It takes multiple people 2 to 3 hours for one disassembly and assembly, which is extremely inconvenient. In addition, each disassembly and replacement of the roller involves roller positioning and calibration, as well as the connection of the power and temperature measurement signal lines of the heating module and many other inconveniences.

[0004] In view of the above situation, the industry is in urgent need of developing a high-temperature hot film pressing roller that can be quickly replaced, capable of rapid disassembly and assembly, while taking into account the line connection of the heating module's power and temperature measurement signals as well as the positioning and calibration of the roller.
