Description

Technical Field

[0001] This utility model relates to the field of glass fiber chopped strand mat drying technology, specifically a drying device for glass fiber chopped strand mat. Background Technology

[0002] After being treated with functional water-based additive solutions, chopped fiberglass mat can enhance its performance and extend its service life, such as improving its anti-aging ability, water resistance, weather resistance, flame retardancy, and UV resistance. However, to accelerate the evaporation of water in the water-based additive solution sprayed on the chopped fiberglass mat, existing drying equipment is commonly used. However, existing drying equipment can only dry chopped fiberglass mat. This means that before drying the mat rolls, the mat rolls that have been sprayed with the water-based additive solution elsewhere need to be transferred to the drying equipment. During this transfer, the water-based additive solution inside the mat rolls not only spills onto the ground, affecting hygiene, but also significantly increases the weight of the mat rolls after being sprayed with the water-based additive solution, making manual handling inconvenient and failing to meet usage requirements. Utility Model Content

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-5 As shown, a drying device for chopped fiberglass mat includes an operating table 1. The operating table 1 is equipped with a winding unit, an unwinding unit, a spraying unit, and a drying unit. The unwinding unit is used to place a roll 11 of chopped fiberglass mat wound with chopped fiberglass mat. The spraying unit is used to spray an aqueous additive solution onto the chopped fiberglass mat. The drying unit is used to dry the chopped fiberglass mat coated with the aqueous additive solution. The winding unit is used to pull out the chopped fiberglass mat from the roll 11 and pass it through the spraying unit and the drying unit in sequence. Finally, the dried chopped fiberglass mat is wound up.

[0018] The aqueous additive solution stored in the liquid storage chamber 21 can be a UV stabilizer solution, an antistatic agent solution, or a flame retardant solution, etc.

[0019] Furthermore, the winding unit includes a winding support frame 2 mounted on the operating table 1, a winding shaft 3 mounted on the winding support frame 2, a fixing plate 4 mounted on the winding shaft 3, a screw cap 5 threadedly connected to one end of the winding shaft 3, a drive shaft 6 mounted on the winding support frame 2, and a motor 7 mounted on the winding support frame 2 for driving the drive shaft 6 to rotate. The drive shaft 6 and the winding shaft 3 are connected by a transmission assembly 8.

[0020] The motor 7 is equipped with a reducer and can be controlled by a PLC system. After the motor 7 is started, it can drive the transmission shaft 6 to rotate. The transmission component 8 can be any of the following: belt drive, synchronous belt drive, gear drive, sprocket drive, etc. The transmission component 8 can drive the take-up shaft 3 to rotate. The take-up shaft 3 holds the core tube that can be wound with glass fiber chopped strand mat. After the core tube is placed on the take-up shaft 3, one end of the core tube abuts against the fixed plate 4. Then, the core tube is fixed between the fixed plate 4 and the fixed plate 4 and the fixed plate 4 and the fixed plate 4 and the fixed plate 4 and the fixed plate 5 by threaded connection between the nut 5 and one end of the take-up shaft 3.

[0021] Furthermore, the unwinding unit includes an unwinding support frame 9 mounted on the operating table 1, an unwinding shaft 10 mounted on the unwinding support frame 9, a fixing plate 2 mounted on the unwinding shaft 10, a screw cap 2 12 threadedly connected to one end of the unwinding shaft 10, and a counterweight plate 13 mounted at the ends of both the winding shaft 3 and the unwinding shaft 10.

[0022] The unwinding shaft 10 is used to place the felt roll 11 wound with glass fiber chopped strand mat. After the felt roll 11 is placed on the unwinding shaft 10, one end of the felt roll 11 needs to abut against the fixing plate 2. Then, the felt roll 11 is fixed on the unwinding shaft 10 by threaded connection between the screw cap 2 12 and the unwinding shaft 10.

[0023] The counterweight 13 can maintain the balance between the take-up shaft 3 and the unwind shaft 10, and improve the stability of the unwind shaft 10 and the take-up shaft 3 during rotation.

[0024] Furthermore, the drying unit includes an oven 14, with a feed port and a discharge port at both ends, both of which are inclined downwards. Roller 15 and roller 2 16 are installed inside the feed port of the oven 14, and roller 3 17 is installed inside the discharge port of the oven 14. The oven 14 has an opening at the top, and a top cover 18 is rotatably connected to the opening at the top of the oven 14. The top cover 18 is connected to the oven 14 by a locking fastener 19, and an electric heating module 20 is installed on the inner side of the top cover 18.

[0025] After the felt roll 11 is installed on the unwinding shaft 10, one end of the chopped fiberglass mat on the felt roll 11 is pulled out and passed under the first roller 15, then over the second roller 16, and then over the third roller 17. Finally, the chopped fiberglass mat is fixed to the core of the take-up shaft 3 with tape or glue.

[0026] When passing the chopped fiber mat through the oven 14, the locking fastener 19 needs to be opened first to flip the top cover 18 off the oven 14 to facilitate the passage of the chopped fiber mat through the oven 14. After the traction of the chopped fiber mat is completed, the top cover 18 is flipped back onto the oven 14, and then the top cover 18 is connected to the oven 14 by the locking fastener 19.

[0027] The electric heating module 20 is a resistance wire heater equipped with a temperature control system to monitor and adjust its temperature so that it is always within the target range for drying glass fiber chopped strand mat.

[0028] Furthermore, the spraying unit includes a liquid storage chamber 21 disposed on the operating table 1, an oven 14 disposed above the liquid storage chamber 21, a liquid pump 22 and an atomizing nozzle 23. The liquid pump 22 is disposed on the feed port of the oven 14, and the atomizing nozzle 23 is disposed inside the feed port of the oven 14. The liquid pump 22 is connected to the liquid storage chamber 21 through a pipe 24.

[0029] When spraying the aqueous additive solution onto the chopped fiberglass mat, the pump 22 needs to be started first. The pump 22 is controlled by a PLC system. The pump 22 draws away the aqueous additive solution from the storage chamber 21 and sprays it onto the surface of the chopped fiberglass mat through the atomizing nozzle 23. The pump 22 is not always in operation, that is, the atomizing nozzle 23 does not continuously spray the aqueous additive solution onto the chopped fiberglass mat. The pump 22 needs to be started and stopped according to the moving speed of the chopped fiberglass mat in the oven 14. That is, the pump 22 is started intermittently, so that the excess aqueous additive solution sprayed on the chopped fiberglass mat can have time to flow back into the storage chamber 21, avoiding a large amount of aqueous additive solution dripping into the oven 14 and saving aqueous additive solution.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
