Description

Technical Field

[0001] The invention relates to the technical field of baking equipment, and in particular to a heating and cooling integrated device for baking equipment. Background Art

[0002] Glass substrate is an important component of liquid crystal display (LCD) devices, and has relatively strict requirements on glass surface defects. The performance and quality of the glass substrate itself are closely related to basic indicators such as resolution, imaging effect, thickness, and weight of the flat panel display. During the production and processing of LCD glass substrates, the glass substrates need to be baked to remove surface organic solvents or water stains.

[0003] Existing baking equipment needs to be cooled down during maintenance after use, and most of them adopt the method of opening the upper cover to cool down naturally. The cooling efficiency is relatively slow, which greatly reduces the maintenance efficiency.

[0004] For example, the invention patent with application publication number CN113600451A discloses a contact-type hot baking device, which is not equipped with a cooling device and can cool down naturally, but the cooling time is long and the efficiency is slow. Therefore, a device to speed up the cooling time is urgently needed. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an integrated heating and cooling device, which can heat the baking oven to improve the baking efficiency of the equipment. When maintenance is required, the inside of the baking oven can be cooled to reduce the cooling time. The integrated setting can reduce the number of holes in the baking oven.

[0006] Specifically, the present invention discloses a heating and cooling integrated device for baking equipment, which is arranged on a baking box and includes: a heating component and a cooling component;

[0007] A heating assembly, comprising a heater and a heating pipe, wherein one end of the heating pipe is connected to the heater and the other end extends into the baking oven;

[0008] The cooling component comprises a cooling pipe and a cooling valve. The cooling pipe is connected to the heating pipe, and the cooling valve is arranged on the cooling pipe.

[0009] The benefit of adopting the above technical solution is that the heating component and the cooling component are arranged in one piece, which reduces the occupied space and equipment opening, improves the working efficiency of the equipment, and reduces the cooling time of the equipment.

[0010] Furthermore, the heating pipe is connected to a plurality of branch pipes, and the branch pipes extend into the side of the baking oven.

[0011] The benefit of adopting the above technical solution is that by setting up multiple branch pipes, the incoming cold air or hot air can be better dispersed into the baking oven, making the heating or cooling more uniform and improving the heating and cooling efficiency.

[0012] Furthermore, an air inlet chamber is provided on the side of the baking oven, the branch pipe extends into the air inlet chamber, and the side of the air inlet chamber is connected to the baking oven.

[0013] The benefit of adopting the above technical solution is that the setting of the air inlet chamber helps to buffer the incoming gas, preventing the gas in the pipeline from directly blowing the product to cause the product to shift and affect the product removal.

[0014] Furthermore, a baffle is provided on the side of the air inlet chamber, and an adjustable gap is provided above the baffle and between the top of the baking oven.

[0015] The benefit of adopting the above technical solution is that the baffle is set to block the gas and the gap is set to adjust the size and position of the air intake, which is suitable for different production needs.

[0016] Furthermore, the cooling pipeline is connected to a refrigeration device.

[0017] The benefit of adopting the above technical solution is that the refrigeration device is used to generate cold air. When cooling is required, the valve of the cooling pipe is opened to quickly cool the baking oven, thereby reducing the maintenance time of the baking oven and improving processing efficiency.

[0018] Furthermore, the baking oven is provided with a waste gas collection pipe.

[0019] The benefit of adopting the above technical solution is that the waste gas collection pipe can collect the waste gas generated during the drying process inside the equipment, which is then discharged after being discharged after treatment, thus avoiding waste gas pollution to the environment.

[0020] Furthermore, the heating pipe is connected to a cleaning pipe, and a cleaning valve is provided on the cleaning pipe.

[0021] The benefit of adopting the above technical solution is that during use, dust will accumulate in the heater. If it is not cleaned in time, it will enter the baking box and contaminate the products being baked, affecting the product quality. The heater needs to be cleaned. When the heater needs to be cleaned, open the cleaning valve and the cleaned gas is discharged from the cleaning pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-3 As shown, the present invention discloses a heating and cooling integrated device for baking equipment, which is arranged on a baking box 3 and includes: a heating component and a cooling component;

[0030] A heating assembly, comprising a heater 1 and a heating pipe 2, wherein one end of the heating pipe 2 is connected to the heater 1, and the other end extends into the baking oven 3;

[0031] The cooling component includes a cooling pipe 4 and a cooling valve 5 . The cooling pipe 4 is connected to the heating pipe 2 , and the cooling valve 5 is arranged on the cooling pipe 4 .

[0032] The benefit of adopting the above technical solution is that, in order to solve the problem of cooling the original baking oven, which requires a long time for natural cooling, without adding a separate air inlet, the air inlet of the baking box 3 is added to a pipeline and controlled by an automatic valve. The pipeline is closed during equipment maintenance, and the cooling valve 5 is opened. Cold air enters the baking box 3 from the heating pipe 2. When the upper cover is not opened or is rarely opened, the temperature inside the furnace body is cooled down. On the one hand, the cooling time can be accelerated. On the other hand, since the inside is in a state of slight positive pressure after the internal pressure is injected, the possibility of foreign matter falling into the oven during the cooling process is eliminated.

[0033] In some embodiments, the heating pipe 2 can adopt the following structural scheme, the heating pipe 2 is connected to a plurality of branch pipes 21, and the branch pipes 21 extend into the side of the baking oven 3. The heater 1 can be a pipeline heater with a simple structure and convenient control.

[0034] The benefit of adopting the above technical solution is that by providing a plurality of branch pipes 21, the incoming cold air or hot air can be better dispersed into the baking oven 3, so that the heating or cooling is more uniform, thereby improving the heating and cooling efficiency.

[0035] In some embodiments, the baking oven 3 can adopt the following structural scheme, wherein an air inlet chamber 31 is provided on the side of the baking oven 3, a cavity is provided inside the air inlet chamber 31, the branch pipe 21 extends into the air inlet chamber 31, and the side of the air inlet chamber 31 is connected to the interior of the baking oven 3.

[0036] The benefit of adopting the above technical solution is that the setting of the air inlet chamber 31 helps to buffer the incoming gas, avoiding the gas in the pipeline from directly blowing the product to cause the product to shift and affect the product removal.

[0037] In some embodiments, the baking oven 3 may adopt the following structural scheme: a baffle 32 is provided on the side of the air inlet chamber 31 , and an adjustable gap is provided above the baffle 32 and the top of the baking oven 3 .

[0038] The benefit of adopting the above technical solution is that the baffle 32 is set to block the gas and the gap set can adjust the size and position of the air intake, which is suitable for different production needs. The side of the baffle 32 is provided with vertically set strip holes, and the screws pass through the strip holes and are fixed to the side of the air intake chamber 31. When adjustment is needed, it is only necessary to adjust the position of the baffle 32 to change the size of the upper air intake gap, which is convenient for adjustment.

[0039] In some implementation schemes, the cooling pipe 4 may adopt the following structural scheme, wherein the cooling pipe 4 is connected to a refrigeration device, and the refrigeration device provides cold air.

[0040] The benefit of adopting the above technical solution is that the refrigeration device is used to generate cold air. When cooling is required, the valve of the cooling pipe 4 is opened to quickly cool the baking oven 3, thereby reducing the maintenance time of the baking oven 3 and improving the processing efficiency.

[0041] In some embodiments, the baking oven 3 may adopt the following structural scheme, and the baking oven 3 is provided with a waste gas collection pipe 33.

[0042] The benefit of adopting the above technical solution is that the waste gas collection pipe 33 can collect the waste gas generated during the drying process inside the equipment, which is led out through the waste gas collection pipe 33 for collection and then discharged after treatment, thereby avoiding waste gas pollution to the environment.

[0043] In some embodiments, the heating pipe 2 may adopt the following structural scheme: the heating pipe 2 is connected to a cleaning pipe 6, a cleaning valve 61 is provided on the cleaning pipe 6, and the heating pipe 2 and the cleaning pipe 6 are connected via a three-way connector.

[0044] The benefit of adopting the above technical solution is that during use, dust will accumulate in the heater. If it is not cleaned in time, it will enter the baking box and contaminate the products being baked, affecting the product quality. The heater needs to be cleaned. When the heater needs to be cleaned, open the cleaning valve and the cleaned gas is discharged from the cleaning pipe.

[0045] There are three working states in the working process. The first is the heating state. The heater 1 is started, the heating valve is opened, the cooling valve 5 and the cleaning valve 61 are closed, and the heated air enters the baking oven 3 from the branch pipe 21 to quickly dry the substrate and take away the residual organic matter on the substrate. The generated waste gas is collected from the waste gas collection pipe 33, and the waste gas collection pipe 33 is connected to the waste gas treatment device to treat the waste gas;

[0046] Then comes the cooling state. When maintenance is needed, the upper cover only needs to be opened slightly or not opened, the heating valve is closed, the cooling valve 5 is opened, and the cleaning valve 61 is closed. At this time, cold air enters the branch pipe 21 from the cooling pipe 4, and also enters the air inlet chamber 31 from the branch pipe 21 to quickly cool down the oven 3. At the same time, the air continues to enter to form a slightly positive state in the oven 3 to prevent foreign matter from entering the oven 3.

[0047] The last state is the cleaning state, in which the heating valve is closed, the cooling valve 5 is closed, the cleaning valve 61 is opened, and the clean air enters the cleaning pipe 6 through the heater, and the inside of the heater is cleaned.

[0048] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, all of which fall within the protection scope of the present invention.
