Description

Technical Field

[0001] This utility model relates to the technical field of silicon steel processing equipment, specifically a temperature control device for silicon steel coated plates. Background Technology

[0002] Temperature control is crucial in the production of silicon steel coated sheets. The coating and drying processes for silicon steel coated sheets have strict temperature requirements. If the temperature is too high, the coating may dry too quickly, leading to surface cracks and poor adhesion between the coating and the silicon steel substrate; conversely, if the temperature is too low, the coating will not dry completely, affecting subsequent processing performance and product quality. Therefore, temperature control of silicon steel coated sheets is necessary.

[0003] In the prior art, utility model patent CN202020999305.9 discloses a coating board curing oven, including: a curing oven and a power supply; the curing oven is provided with a curing channel, which is a channel for conveying the coating board; infrared curing devices are provided on the upper and lower sides of the curing channel, the infrared curing devices generate infrared rays, the infrared curing devices are connected to the power supply, and the power supply provides electrical energy to the infrared curing devices; and the distance between the infrared curing devices and the coating board is 30-40cm. The coating board curing oven cures the coating board by generating infrared rays from the infrared curing devices. The infrared rays generated by the infrared curing devices can continue to heat the coating, causing the resin molecules in the coating to react and release solvent, thereby curing the coating.

[0004] The aforementioned patent provides a device for curing a coated plate on a silicon steel plate. This device uses an infrared curing unit for heating, achieving rapid temperature rise in the curing oven and shortening the preheating time of the coated plate curing oven, thereby saving energy.

[0028] Example 1

[0029] like Figures 1-3 and Figure 6As shown, a temperature control device for silicon steel coated plates includes a drying chamber 1 and a silicon steel sample 4.

By setting the placement platform 102, the silicon steel plate placement rack 3 can be placed on the horizontal surface of the placement platform 102, which makes it convenient to suspend the silicon steel plate placement rack 3 in the drying cavity 101. A silicon steel sample 4 is placed on a silicon steel plate placement rack 3. The silicon steel plate placement rack 3 includes a rotating rod 301, a baffle 302, and a handle 303. Several rotating rods 301 are arranged parallel to each other along the length of the silicon steel plate placement rack 3. The silicon steel sample 4 is placed on the silicon steel plate placement rack 3 through the rotating rods 301. A baffle 302 is detachably inserted into one end of the silicon steel plate placement rack 3. A handle 303 is provided on the end face of the frame of the silicon steel plate placement rack 3 at the same end as the baffle 302. By rotating the rotating rods 301 in the silicon steel plate placement rack 3, it is convenient to slide and push the silicon steel sample 4 onto the silicon steel plate placement rack 3. At the same time, the baffle 302 can also block the placement opening of the silicon steel plate placement rack 3 to prevent the silicon steel sample 4 from falling off. Meanwhile, the baffle 302 is inserted into the frame of the silicon steel plate placement rack 3, which can facilitate installation and disassembly.

[0030] like Figures 2-7 and Figure 8As shown, the heating device 5 is equipped with a heating tube 501, and the air-cooling device 6 is equipped with an air outlet plate 604. The heating tube 501 and the air outlet plate 604 are both located inside the drying chamber 101 on the upper and lower sides of the silicon steel plate placement rack 3. By sequentially arranging the heating tube 501 and the air outlet plate 604 on the upper and lower sides of the silicon steel plate placement rack 3, when heating is required, both the upper and lower sides of the silicon steel sample 4 can be heated simultaneously, and when air cooling is required, both the upper and lower sides of the silicon steel sample 4 can be air-cooled. The heating device 5 includes a heating tube 501. The heating device 5 is provided on the side of the drying chamber 1, and several heating tubes 501 are provided on the heating device 5.

By arranging the heating tubes 501 parallel to each other along the length of the drying chamber 1, the heating tubes 501 cover the entire silicon steel plate placement rack 3, and the entire silicon steel sample can be heated. The air-cooling device 6 includes a cold air pump 601. The cold air pump 601 is installed on the outside of the drying chamber 1. A main air duct 602 is installed at the air outlet of the cold air pump 601. Branch air ducts 603 are connected to the main air duct 602.

The horizontal pipes 605 also cover the entire silicon steel plate placement rack 3. Each horizontal pipe 605 has several air outlets arranged along its length towards the silicon steel sample 4, so that each part of the silicon steel sample 4 can be cooled by air. The cold air pump 601 can deliver air to each horizontal pipe 605 through the main air duct 602 and the branch air ducts 603.

[0031] like Figures 1-4As shown, a heat dissipation device 8 is embedded in the side panel of the drying oven 1. The heat dissipation device 8 includes a mounting block 801 and a movable insert plate 804. A mounting block 801 is provided on the rear side of the drying oven 1.

The movable insert plate 804 includes a slide rod 805. Push plates 807 and limiting plates 808 are respectively located on both sides of the mounting block 801 at both ends of the movable insert plate 804.

A spring 809 is fitted onto the portion of the slide rod 805 located between the limiting plates 808 and the mounting block 801. Electric telescopic rods 803 are located on both sides of the mounting block 801. The telescopic ends of the electric telescopic rods 803 are fixedly abutted against the push plates 807. The electric telescopic rods 803 can push the push plates 807, which in turn causes the movable insert plate 804 to slide within the mounting block 801. This allows the solid portion of the movable insert plate 804 and the ventilation hole 806 to be aligned with the cooling fan 802 as needed. When the electric telescopic rods 803 retract, the spring 809 automatically returns the movable insert plate 804 to its original position. A temperature detector 7, a platinum resistance temperature sensor, is installed on the inner side of the cover 2. A controller 9 is installed on the outer side, electrically connected to the heating device 5, the air-cooling device 6, the temperature detector 7, and the heat dissipation device 8. A PLC receives temperature data from the temperature sensor unit. The controller 9 is a PLC controller with a built-in advanced temperature control algorithm. Based on preset temperature parameters, it precisely controls the heating device 5, the air-cooling device 6, and the heat dissipation device 8. When the temperature is higher than the set value, the control unit reduces the power of the heating device 5 and activates the air-cooling device 6 and the heat dissipation device 8. When the temperature is lower than the set value, it increases the power of the heating device 5 and shuts down the air-cooling device 6 and the heat dissipation device 8. The controller 9 also has a display screen and an operation panel. Operators can set temperature parameters through the operation panel and view real-time temperature data and device operating status on the display screen.
