Description

Technical Field

[0001] This utility model relates to the field of prepreg production technology, specifically to a glue tank heating structure for a glass fiber cloth gluing device. Background Technology

[0002] Fiberglass cloth is one of the main materials for prepregs (PP sheets, adhesive sheets). After being soaked in resin in the glue tank of the gluing device, the fiberglass cloth undergoes drying, cutting and other processes to form a prepreg with a certain degree of flexibility that can be cured under heat and pressure.

[0003] In the resin impregnation process, the temperature of the resin solution is not constant due to seasonal and regional environmental factors. Summer temperatures are higher, while winter temperatures are lower, and the fluidity of the resin solution is affected by temperature, especially in northern regions. Fluidity affects the coating effect; poorer fluidity requires more impregnation time. Current coating equipment either does not consider heating the resin solution in low-temperature environments or places the equipment close to the oven in the prepreg production line. However, such placement leads to excessively high resin solution temperatures in summer, accelerating moisture evaporation and also affecting the coating effect. Therefore, it is necessary to design a heating structure for the resin tank to solve the resin fluidity problem in winter. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a glue tank heating structure for a glass fiber cloth gluing device, which can increase the temperature of the glue liquid in a low-temperature environment and ensure its fluidity.

[0005] The technical solution of this utility model is:

[0006] A glue tank heating structure for a fiberglass cloth gluing device includes:

[0007] The hot water transfer chamber is located at the bottom of the rubber tank and is connected to the water inlet pipe, the drain pipe, and the vent pipe.

[0008] The heating chamber is located at the bottom of the heat transfer chamber. One end is connected to the air inlet pipe and the other end is connected to the air outlet pipe. The air inlet pipe is connected to the exhaust port of the oven of the prepreg production line, and a control valve for controlling the flow rate is installed on the air inlet pipe.

[0009] A thermometer is installed on the side of the glue tank, with its sensing end extending into the glue liquid inside the tank.

[0010] In a further embodiment, valves are installed on both the inlet pipe and the outlet pipe.

[0011] In a further embodiment, the inner end of the exhaust pipe is connected to the top of the hot water transfer chamber, and the outer end is located outside the hot water transfer chamber and bent upwards at a certain height, so that the pipe opening at the outer end is higher than the top of the hot water transfer chamber.

[0012] In a further embodiment, a number of fins are fixed to the bottom surface of the base plate of the hot water transfer chamber. The fins are located inside the heating chamber and are used to absorb the heat from the high-temperature exhaust gas inside the heating chamber and conduct it to the base plate of the hot water transfer chamber, thereby heating the water stored inside the hot water transfer chamber.

[0013] Compared with the prior art, this utility model has the following advantages: This utility model uses the high-temperature exhaust gas from the oven of the prepreg production line to heat the water in the hot water transfer chamber, thereby heating the adhesive liquid to keep it within a suitable temperature range, ensuring its fluidity and adhesive application effect.

[0021] like Figure 1 As shown, this embodiment provides a glue tank heating structure for a glass fiber cloth gluing device, including:

[0022] A hot water transfer chamber 5 is located at the bottom of the glue tank 1. Its shape can be exactly the same as the bottom surface of the glue tank 1, completely covering it, or it can cover most of the bottom surface of the glue tank 1. One end of the hot water transfer chamber 5 is connected to a water inlet pipe 12, and the other end is connected to a drain pipe 13. Both the water inlet pipe 12 and the drain pipe 13 are equipped with manual valves 3. In order to facilitate venting during water filling so that the hot water transfer chamber 5 is completely filled with water, the hot water transfer chamber 5 is also connected to an exhaust pipe 7. The inner end of the exhaust pipe 7 is connected to the top of the hot water transfer chamber 5, and the outer end is located outside the hot water transfer chamber 5 and bends upward to a certain height so that the pipe opening at the outer end is higher than the top of the hot water transfer chamber 5.

[0023] Heating chamber 9; located at the bottom of heat transfer chamber 5, one end is connected to air inlet pipe 10 and the other end is connected to air outlet pipe 14. Air inlet pipe 10 is connected to the exhaust port of the oven of the prepreg production line, thereby introducing the high-temperature exhaust gas of the oven. A control valve 11 for controlling the flow rate is provided on air inlet pipe 10. Several fins 8 are fixed on the bottom surface of the bottom plate 6 of heat transfer chamber 5. The fins 8 are located in heating chamber 9 and are used to absorb the heat of the high-temperature exhaust gas in heating chamber 9 and conduct it to the bottom plate 6 of heat transfer chamber 5, thereby heating the water stored in heat transfer chamber 5.

[0024] The thermometer 4 is installed on the side of the glue tank 1, with its sensing end extending into the glue liquid 2 inside the glue tank 1.

[0025] The exhaust pipe 14 is connected to a waste gas treatment device, such as an incinerator, for combustion treatment. The drain pipe 13 can discharge directly or be introduced into the factory's water treatment system. To reduce moisture evaporation, a cap can be installed at the outer end of the exhaust pipe 7.

[0026] The working principle of this embodiment is as follows:

[0027] When filling with water, close valve 3 of drain pipe 13, open the cap at the outer end of vent pipe 7, and open valve 3 of inlet pipe 12 to fill the hot water chamber 5 with water until it overflows from vent pipe 7. Since the inner end of vent pipe 7 is connected to the top of hot water chamber 5, the overflow from vent pipe 7 indicates that hot water chamber 5 is full of water and can conduct heat smoothly. Then, close valve 3 of inlet pipe 12. When drainage is required, open valve 3 of drain pipe 13.

[0028] Open the control valve 11 to introduce the high-temperature exhaust gas from the oven. After the high-temperature exhaust gas enters the heating chamber 9, it exchanges heat with the fins 8 and the bottom plate 6 of the hot water transfer chamber 5 to heat the water in the hot water transfer chamber 5. The exhaust gas is then discharged from the exhaust pipe 14.

[0029] After the water in the hot water chamber 5 is heated, it is transferred to the bottom plate of the glue tank 1 to heat the glue liquid 2 inside the glue tank 1.

[0030] Workers can observe the temperature of the adhesive liquid 2 through thermometer 4, and adjust the opening of control valve 11 to control the flow rate of high-temperature exhaust gas entering heating chamber 9, thereby controlling the heat transfer process and ultimately keeping the temperature of the adhesive liquid 2 within a suitable range.

[0031] This embodiment is mainly used to heat the adhesive liquid 2 when the ambient temperature is low, such as in winter. When the ambient temperature is high in summer, if the adhesive liquid 2 can maintain a suitable temperature, the control valve 11 and the valve 3 of the water inlet pipe 12 can be closed to stop heating the adhesive liquid 2.

[0032] The above description is merely a preferred embodiment of this utility model. For those skilled in the art, various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
