[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1 - Figure 6As shown in the figure, the utility model provides a drying and curing furnace for fiberglass felt forming, which includes a mesh belt transmission part 1. A baffle 2 is arranged on the surface of the mesh belt transmission part 1. A drying and dust-proof component 3 is connected to the inner side of the baffle 2. The drying and dust-proof component 3 includes a curing furnace main body 301. A hot air blower 302 is connected to the top of the curing furnace main body 301. Jacks 303 are opened on both inner walls of the curing furnace main body 301 close to the hot air blower 302. A dust-proof net 304 is connected to the top of the jack 303. Slot holes 305 are opened on both sides of the dust-proof net 304. A first spring 306 is connected to the inside of the slot hole 305. A handle 307 is connected to one side of the first spring 306. An insertion block 308 is connected to one side of the handle 307. Second springs 309 are connected to the four corners inside the dust-proof net 304. A top block 310 is connected to the bottom of the second spring 309. An inclined opening is arranged on one side of the insertion block 308. An elastic structure is formed between the handle 307 and the first spring 306. The position and size of the insertion block 308 match the position and size of the jack 303. A snap connection is formed between the insertion block 308 and the jack 303. The outer shape of the top block 310 is cylindrical. An elastic structure is formed between the top block 310 and the second spring 309.

[0025] The effect achieved by the entire embodiment 1 is that when the fiberglass felt is placed on the mesh belt transmission part 1 and the hot air blower 302 is turned on to dry and cure the fiberglass felt, the dust-proof net 304 can isolate external dust. When it is necessary to disassemble and clean the dust-proof net 304 after long-term use, two groups of handles 307 can be pushed inward simultaneously, so that the handles 307 can squeeze the first spring 306 and drive the insertion block 308 to be pulled out of the jack 303. Then the second spring 309 will push the top block 310 through its own elastic force, and push the dust-proof net 304 out of the top of the curing furnace main body 301, and then clean the dust-proof net 304. When it is necessary to install the dust-proof net 304 after cleaning the dust-proof net 304, the dust-proof net 304 can be directly pushed towards the top of the curing furnace main body 301. When the insertion block 308 is squeezed, it will automatically shrink towards the slot hole 305. When the dust-proof net 304 is completely pushed into the top of the curing furnace main body 301, the first spring 306 will push the handle 307 through its own elastic force to drive the insertion block 308 to insert into the jack 303 for quick fixation. In this way, the dust-proof net 304 can be used to avoid the problem that dust is adsorbed on the surface of the fiberglass felt during the drying and curing process, which affects subsequent processing.

[0026] Embodiment 2, such as Figure 1 、 Figure 2 and 3As shown, a control component 4 is connected to the front surface of the baffle 2. The control component 4 includes a PLC control panel 401. A temperature sensor 402 is connected to the bottom of one side of the curing furnace main body 301. Electrical connections are formed between the PLC control panel 401 and the temperature sensor 402 and the hot air blower 302 respectively.

[0027] The overall effect achieved by the entire Embodiment 2 is that the internal temperature of the curing furnace main body 301 can be monitored in real time through the PLC control panel 401 and the temperature sensor 402, and the air volume and temperature of the hot air blower 302 can also be controlled through the PLC control panel 401, and adjustments can be made according to the actual situation, improving the overall practicability.

[0028] Working principle: When the hot air blower 302 is turned on to dry and cure the glass fiber mat, external dust can be isolated through the dust-proof net 304. When used for a long time, the dust-proof net 304 can be quickly disassembled and cleaned. Through the dust-proof net 304, it can be avoided that dust is adsorbed on the surface of the glass fiber mat during the drying process, which affects subsequent processing. The internal temperature of the curing furnace main body 301 can be monitored in real time through the PLC control panel 401 and the temperature sensor 402, and the air volume and temperature of the hot air blower 302 can also be controlled through the PLC control panel 401, improving the overall practicability.

[0029] The above is only the preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
