Description

Technical Field

[0001] The utility model belongs to the technical field of glass fiber reinforced plastic plates, and in particular relates to a rapid cooling device for glass fiber reinforced plastic plates. Background Art

[0002] On the production line, after the FRP sheet comes out of the oven, it will enter the roller glue machine for surface roller glue treatment. However, the temperature of the FRP sheet just out of the oven is relatively high, and the high temperature at this time will affect the curing effect of the glue on the FRP sheet. Therefore, the FRP sheet needs to be cooled down.

[0003] In the original production line, the distance between the oven outlet and the roller glue equipment is lengthened to allow the FRP sheet to cool naturally to a temperature suitable for roller glue during the conveying process. However, this cooling method has many disadvantages. For example, too long a conveying distance will reduce production efficiency and it is difficult to control the FRP sheet to reach a suitable cooling temperature. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a FRP plate rapid cooling device for solving the technical problems in the prior art that the FRP plate adopts natural cooling, which affects the production efficiency and the cooling temperature is difficult to accurately control.

[0005] The utility model solves the above technical problems with the following technical solutions: A glass fiber reinforced plastic plate rapid cooling device, comprising:

[0006] A fixed frame, the fixed frame is arranged between the oven and the rubber roller device, and the glass fiber reinforced plastic plate passes through the middle of the fixed frame;

[0007] A plurality of air curtain machines, wherein the plurality of air curtain machines are arranged above and below the fixed frame, and the upper air curtain machines and the lower air curtain machines are arranged in a staggered manner, and the air outlets of the air curtain machines face the glass fiber reinforced plastic plate;

[0008] A tray is also provided at the air inlet of the air curtain machine above, and the tray is used to hold cold water or ice cubes.

[0009] The utility model utilizes an air curtain machine to increase the air flow rate on the surface of the glass fiber reinforced plastic plate to achieve the purpose of cooling. However, in order to improve the cooling efficiency, a tray with cold water or ice cubes is arranged at the air inlet of the air curtain machine to achieve the purpose of lowering the air temperature at the air inlet of the air curtain machine, thereby increasing the temperature difference between the air and the glass fiber reinforced plastic plate to improve the cooling efficiency.

[0010] Furthermore: a plurality of sequentially arranged conveying rollers are also provided on the fixed frame, and the conveying rollers are located below the glass fiber reinforced plastic plate. Tensioning rollers are also provided on both sides of the fixed frame, and the tensioning rollers are used to clamp the gel coat of the glass fiber reinforced plastic plate.

[0011] The beneficial effect of this step is that the conveying roller is used to support the FRP plate to prevent the FRP plate from being deformed under the wind force of the air curtain machine, while the tensioning roller is used to limit the inward retraction of the gel coat.

[0012] Furthermore: the distance between the air outlet of the air curtain machine and the glass fiber reinforced plastic plate is 250±10mm.

[0013] The beneficial effect of adopting this step: the appropriate distance is obtained by combining the air outlet speed and air outlet pressure of the air curtain machine.

[0014] Furthermore, when the number of the air curtain machines above is even, every two of the air curtain machines form a group, the air inlets of each group of the air curtain machines are arranged opposite to each other, and the tray is located between each group of the air curtain machines.

[0015] The beneficial effect of adopting this step is that the number of pallets can be saved.

[0016] Furthermore: a cover plate is provided on the top surface of each group of the air curtain machines.

[0017] The beneficial effect of adopting this step is: the cover plate can block the air from entering from the top of the air curtain machine, so that the air can only enter from the side of the air curtain machine. The air entering from the side will drive the cold water to oscillate violently, thereby increasing the heat exchange rate between the air and the cold water.

[0018] Furthermore: the outer side of the tray is also wrapped with heat insulating material.

[0019] The beneficial effect of adopting this step is that the insulation material can prevent condensation from forming on the outside of the tray, thereby preventing the condensation from falling on the FRP plate and affecting the subsequent roller glue.

[0020] Furthermore: wind shields are arranged around the fixed frame.

[0021] The beneficial effect of adopting this step is: the wind shield can slow down the escape speed of the cold air blown out by the air curtain machine, allowing the cold air to contact the fiberglass plate for a longer time, thereby improving the cooling effect.

[0022] Furthermore: a control cabinet is also provided outside the fixed frame, and the control cabinet is provided with a plurality of control circuits electrically connected one by one with a plurality of the air curtain machines.

[0023] The beneficial effect of adopting this step is: the total cooling capacity of the air curtain machine can be selected according to the ambient temperature of the production site and the temperature of the glass fiber reinforced plastic plate when it leaves the oven, and the size of the total cooling capacity can be controlled by the control circuit to control any number of air curtain machines to achieve the purpose of energy saving and temperature control.

[0024] The beneficial effects of the utility model are:

[0025] The present application utilizes multiple air curtain machines mounted above and below a fixed frame to achieve the effect of blowing air on the front and back sides of the FRP plate, and uses air cooling to control the temperature of the FRP plate. The air output of the air curtain machine is controlled in multiple gears, and combined with the form in which multiple air curtain machines can be controlled individually, a temperature control mode with adjustable cooling capacity is formed. The FRP plates with different production environment temperatures and different plate temperatures can be quickly cooled, so that they can enter the rolling process at a temperature that meets the requirements of the rolling process through a short transportation distance, thereby achieving the effect of improving production efficiency and improving temperature control accuracy.

[0036] Example

[0037] like Figure 1 As shown, the utility model provides a glass fiber reinforced plastic plate rapid cooling device, comprising:

[0038] A fixed frame 2, wherein the fixed frame 2 is disposed between the oven 1 and the rubber roller device 3, and the glass fiber reinforced plastic plate 4 passes through the middle of the fixed frame 2;

[0039] A plurality of air curtain machines 7, wherein the plurality of air curtain machines 7 are arranged above and below the fixed frame 2, and the upper air curtain machines 7 and the lower air curtain machines 7 are staggered, and the air outlets of the air curtain machines 7 face the glass fiber reinforced plastic plate 4;

[0040] A tray 9 is also provided at the air inlet of the air curtain machine 7 above, and the tray 9 is used to hold cold water or ice cubes.

[0041] The utility model utilizes the air curtain machine 7 to increase the air flow rate on the surface of the glass fiber reinforced plastic plate 4 to achieve the purpose of air cooling and temperature reduction. However, in order to improve the cooling efficiency, a tray 9 with cold water or ice cubes is also provided at the air inlet of the air curtain machine 7 to achieve the purpose of reducing the air temperature at the air inlet of the air curtain machine 7, thereby increasing the temperature difference between the air and the glass fiber reinforced plastic plate 4 to improve the cooling efficiency.

[0042] On the basis of the above technical solution, a plurality of conveying rollers 5 arranged in sequence are further provided on the fixed frame 2, and the conveying rollers 5 are located below the fiberglass plate 4. Tensioning rollers 6 are also provided on both sides of the fixed frame 2, and the tensioning rollers 6 are used to clamp the gel coat of the fiberglass plate 4.

[0043] The conveying roller 5 is used to support the FRP plate 4 to prevent the FRP plate 4 from being deformed under the wind force of the air curtain machine 7, while the tensioning roller 6 is used to limit the inward retraction of the gel coat, wherein the gel coat is the base material located under the FRP plate 4, and the width of the gel coat is generally greater than the width of the FRP plate 4.

[0044] On the basis of the above technical solution, the distance between the air outlet of the air curtain machine 7 and the glass fiber reinforced plastic plate 4 is 250±10 mm.

[0045] The appropriate distance obtained by combining the air outlet speed and air outlet pressure of the air curtain machine 7 can ensure that the wind blown by the air curtain machine 7 can reach the surface of the glass fiber reinforced plastic plate 4, while not causing a large wind pressure to avoid affecting the shape of the glass fiber reinforced plastic plate 4.

[0046] On the basis of the above technical solution, when the number of the air curtain machines 7 above is even, every two of the air curtain machines 7 form a group, the air inlets of each group of the air curtain machines 7 are arranged opposite to each other, and the tray 9 is located between each group of the air curtain machines 7 .

[0047] This can save the number of trays, and the air inlets of the two air curtain machines 7 relative to the tray 9 can increase the flow rate of the air above the tray 9, thereby driving more air to exchange heat with cold water, allowing more air to cool down, and achieving a good cooling effect.

[0048] On the basis of the above technical solution, a cover plate 8 is provided on the top surface of each group of the air curtain machines 7 .

[0049] The cover plate 8 can block the air from entering from the top of the air curtain machine 7, so that the air can only enter from the side of the air curtain machine 7. The air entering from the side will quickly pass over the tray 9, causing the cold water to oscillate violently, thereby increasing the heat exchange rate between the air and the cold water.

[0050] On the basis of the above technical solution, the outer side of the tray 8 is also wrapped with a heat insulating material.

[0051] The heat insulating material can prevent condensation water from being generated on the outer side of the tray 9, thereby preventing the condensation water from falling on the glass fiber reinforced plastic plate 4 and affecting the subsequent rolling glue.

[0052] On the basis of the above technical solution, wind shields 11 are provided around the fixed frame 2 .

[0053] The wind shield 11 can slow down the dissipation speed of the cold air blown out by the air curtain machine 7, so that the contact time between the cold air and the glass fiber reinforced plastic plate 4 is longer, thereby improving the cooling effect.

[0054] On the basis of the above technical solution, a control cabinet 10 is further provided outside the fixed frame 2 , and the control cabinet 10 is provided with a plurality of control circuits electrically connected one by one with a plurality of the air curtain machines 7 .

[0055] The air curtain machine 7 itself has a multi-speed adjustment function. The total cooling capacity of the air curtain machine 7 can be selected according to the ambient temperature of the production site and the temperature of the glass fiber reinforced plastic plate 4 when it comes out of the oven. The size of the total cooling capacity can be controlled by the control circuit to control any number of air curtain machines 7 to work in different gears to achieve the purpose of energy saving and temperature control.

[0056] In addition, the installation method and fixing structure of the air curtain machine belong to conventional technologies well known to those skilled in the art, and thus will not be described in detail.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
