Description

[0030] The following further describes the present utility model in detail with reference to the drawings:

[0031] See Figure 1 , the present utility model provides a forming edge pulling wheel cooling system for substrate glass production, including a cooling air duct 1, a cooling air duct fixing bracket 3, a pulling wheel fixing body 4, a return air noise reduction device 5, a bracket fixing screw 6, a locking nut 7, a front end gasket 8, a rear end gasket 9, a precision rotameter 10, a flow regulating valve 11, an air compressor 12, and an air filter triple unit 13.

[0032] One end of the cooling air duct 1 is inserted into the pulling wheel 2, and the end of the cooling air duct 1 inserted into the pulling wheel 2 is provided with a U-shaped opening, as Figure 3As shown, and at a certain distance from the bottom of the edge pulling wheel, to ensure good cooling effect of the edge pulling wheel. The other end of the cooling air duct 1 is connected to an air compressor 12 for providing air at a certain pressure. The edge pulling wheel 2 is installed in the edge pulling wheel fixing body 4, and the edge pulling wheel fixing body 4 is used to limit and fix the installation position of the edge pulling wheel. The cooling air duct 1 and the return air noise reduction device 5 are both fixedly installed on the cooling air duct fixing bracket 3 through lock nuts 7. The lock nuts 7 are installed on the cooling air duct fixing bracket 3, and the return air noise reduction device 5 is installed to reduce the noise of the cooling return air and change the flow direction of the return air. The cooling air duct fixing bracket 3 is fixedly installed on the edge pulling wheel fixing body 4 through bracket fixing screws 6.

[0033] As Figure 2 As shown, one end of the return air noise reduction device 5 is provided with an outer sealing groove, and the other end of the return air noise reduction device 5 is provided with an inner sealing groove. A front end sealing pad 8 is installed in the outer sealing groove, and a rear end sealing pad 9 is installed in the inner sealing groove. The front end sealing pad 8 is in close contact with one end face of the edge pulling wheel 2. The front end sealing pad 8 and the rear end sealing pad 9 are used to seal the cooling return air of the edge pulling wheel.

[0034] An air filter triple unit 13 is installed on the pipeline between the air compressor 12 and the cooling air duct 1. The air filter triple unit 13 includes an oil mist separator, a water droplet separator and a pressure reducing valve connected in sequence, and is used to filter the moisture and oil contained in the compressed air and adjust the pressure of the cooling air. A flow regulating valve 11 is installed on the pipeline between the air filter triple unit 13 and the cooling air duct 1, and a precision float flowmeter 10 is installed on the pipeline between the flow regulating valve 11 and the cooling air duct 1 for accurately controlling the flow rate of the cooling air. The pipeline between the air compressor 12 and the cooling air duct 1 is a stainless steel pipe to avoid damage to other equipment such as instruments and meters caused by rust inside the pipeline during long-term use. The outside of the stainless steel pipe is coated with rubber and plastic thermal insulation cotton to prevent excessive temperature fluctuations of the cooling air with seasonal changes from causing production instability.

[0035] Installation method of the forming edge pulling wheel cooling system for substrate glass production of the present utility model:

[0036] The air compressor 12 is fixed in the corresponding air compressor room. Because of the large noise and vibration, it is arranged in a room at a certain distance from the production site. During the process of transporting the cooling air, stainless steel pipes are used for connection to avoid damage to other equipment such as instruments and meters caused by rust inside the pipes after long-term use. And it is covered with rubber and plastic insulation cotton to prevent the cooling air temperature from fluctuating too much with the change of seasons, which may lead to unstable production. The cooling air is transported to the forming operation room by stainless steel pipes and then connected to the air filter triple unit 13, including an oil mist separator, a water droplet separator and a pressure reducing valve, to remove the oil, moisture and adjust the pressure of the cooling air. Then it is connected to the flow regulating valve 11 with stainless steel pipes to control the flow rate of the cooling air, and a precision rotameter 10 is connected to accurately adjust and control the flow rate of the cooling air. The pipe rack adopts a bypass standby design. In case the precision rotameter 10 is damaged, the standby pipeline can be switched in time, and it is convenient for replacement and maintenance without causing great impact on production. Then the cooling air is led to both ends of the upper rear part of the edge roller station with stainless steel pipes, and each part of the pipeline is firmly fixed with pipe clamps and brackets. A flow regulating valve and a special adapter for the conversion hose are installed at the air outlet, and then the connection of the peripheral cooling air is completed.

[0037] When installing the edge roller cooling component, first fix the edge roller 2 in the edge roller fixing body 4. Install the front end gasket 8 in the outer sealing groove on the air return noise reduction device 5, and install the rear end gasket 9 in the inner sealing groove on the air return noise reduction device 5, and the noise reduction component installation is completed. Insert the cooling air pipe 1 into the noise reduction component from one end of the air inlet, and it is required to be inserted from the position of the outer sealing groove at the front end of the noise reduction component. Then install the combination of the noise reduction component and the cooling air pipe 1 on the cooling air pipe fixing bracket 3, and tighten the locking nut 7 until the external hexagon processed on the cooling air pipe 1 is closely attached to the rear end gasket 9. Then check whether the mark on the cooling air pipe 1 is aligned with the rear end face of the edge roller 2 to ensure that the distance between the front inner section of the cooling air pipe 1 and the edge roller 2 is controllable. After confirmation of alignment, confirm that the front end gasket 8 is closely attached to the rear end face of the edge roller 2 to avoid air leakage. Then fix the cooling air pipe fixing bracket 3 on the edge roller fixing body 4 with the bracket fixing screw 6, and tighten the bracket fixing screw 6 to ensure that the cooling air pipe fixing bracket 3 is firmly fixed. Then connect the air inlet and the cooling air outlet of the cooling air pipe 1 with a hose, and the installation of the edge roller cooling system is completed.

[0038] The forming edge pulling wheel cooling system for the production of substrate glass of the present utility model connects high-pressure air into the cooling air duct 1 through a pipeline by an air compressor 12, and after filtration, the head cooling of the edge pulling wheel 2 is achieved by adjusting the intake air volume of the cooling air. The cooling air controls the temperature of the edge pulling wheel 2, further adjusts the thickness of the side plate of the glass plate in the forming furnace and the overall plate width, thereby controlling the shaping of the edge of the glass plate, enabling the glass plate to reach a certain width and achieving the purpose of shaping the glass plate. In addition, the cooling return air of the edge pulling wheel 2 enters the return air noise reduction device 5, reducing the noise, improving the comfort of the working environment, and changing the flow direction of the return air to avoid scalding the operators.
