Cooling is one of the important processes in the production of coated glass. However, existing cooling devices used in coated glass production lack dust prevention measures during operation. When dust falls on the cooling device, it may adhere to the coated glass with the cooling airflow, requiring further processing steps. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cooling device for the production of coated glass, which solves the problem that without relevant dust prevention measures, dust may adhere to the coated glass with the cooling airflow.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for producing coated glass, comprising a production base, the production base having a cooling inner cavity for conveying and cooling the coated glass, a conveying roller being provided in the cooling inner cavity, a refrigerator being installed on the production base, the refrigerator delivering cooling airflow to the cooling inner cavity, and a dust removal component being provided at the bottom of the cooling inner cavity for removing impurities mixed in the airflow.

[0005] The top and bottom of the cooling cavity are provided with several air nozzles for connecting to the refrigeration unit, and the dust removal component is provided on the air nozzle located at the lower end.

[0006] The dust removal component includes a dust removal layer installed on the cooling inner cavity. The dust removal layer has several filter openings adapted to the diameter of the jet nozzle. Several filter holes for filtering the cooling airflow are opened in the filter openings. Dust removal ports with the same diameter and structure as the filter openings are opened between adjacent filter openings. A compensation column group adapted to the dust removal port is provided on the cooling inner cavity bottom plate at the lower end of the dust removal port.

[0007] In one embodiment, the left and right ports of the cooling cavity are equipped with rollers for winding the dust removal layer to switch between the dust removal port and the filter port. A removal plate for removing dust from the dust removal port is installed on the bottom surface of the cooling cavity. The removal plate has a gap groove with a diameter adapted to the nozzle at the installation position. A telescopic rod is installed between the removal plate and the side wall of the cooling cavity. The telescopic rod pushes the removal plate to reciprocate on the dust removal layer.

[0008] In one embodiment, the compensation column assembly includes an embedded groove formed in the bottom plate of the cooling cavity, a chassis is installed in the embedded groove, and a plurality of straight rods adapted to the filter port are installed on the chassis. The extension length of the straight rods on the chassis is equal to the opening thickness of the filter port, and the diameter of the straight rods is smaller than the diameter of the filter port, but the difference between them is compensated by a rubber layer sleeved on the straight rods.

[0009] In one embodiment, a through groove adapted to the structure of the rejection plate is provided on the side wall of the cooling cavity opposite to the mounting surface of the rejection plate, and the through groove establishes a communication channel between the cooling cavity and the outside.

[0010] In one embodiment, the height of the reel is less than the installation height of the conveyor roller.

[0011] In one embodiment, a groove is provided at the bottom of the cooling cavity, and the air nozzle is embedded in the groove.

[0012] Compared with the prior art, the present invention provides a cooling device for the production of coated glass, which has the following advantages:

[0013] In the technical solution disclosed in this utility model, a dust removal layer is provided at the upper end of the air nozzle. On the one hand, it can effectively isolate dust on the dust removal layer and reduce the probability of it entering the air nozzle. On the other hand, it can transfer the cleaning operation of the air nozzle to the dust removal layer, which is easier to clean, thus reducing the difficulty of cleaning and increasing the cleaning efficiency.

[0014] By setting a compensation column group at the installation position of the dust removal layer, this utility model can compensate and fill the filter port, increasing the probability that dust is carried away from the interior of the dust removal layer. On the other hand, the reciprocating motion and the removal plate at the top of the dust removal layer can be used to clean the dust covering the dust removal layer, reducing the probability that dust is carried to the coated glass by the airflow.

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Figures 1-3 This is an embodiment of the present invention, and the specific problem addressed by this embodiment is that: after the glass reaches the tempering temperature in the heating chamber, it needs to be transferred to the cooling section for tempering treatment. Cooling is one of the important processes in the production of coated glass. However, existing cooling devices used in coated glass production lack relevant dust prevention measures during operation. When dust falls on the cooling device, it may adhere to the coated glass with the cooling airflow, requiring further processing steps. Based on an existing cooling device for coated glass production with application number 202023128018.X, a workbench and a support frame are disclosed. The support frame is fixedly connected above the workbench, and a control panel is set on the side of the support frame. A refrigeration unit 4 is installed on the top of the support frame. The air outlet of the refrigeration unit 4 is connected to the air inlet of an air guide coil. The upper end of the air guide coil is fixedly connected to the support frame through a connecting rod, and the bottom of the air guide coil is connected to an air outlet. A telescopic rod 58 is installed on one side of the air guide coil, and a metal mesh plate is detachably connected to the bottom of the telescopic rod 58. The surface rotation connection rotating seat provides a solution for cooling coated glass, but it lacks a corresponding structure or solution for dust prevention of the air outlet. Therefore, this solution provides a cooling device for coated glass production based on existing technology. By setting a dust removal layer 51 on the upper end of the air nozzle 6, dust can be effectively isolated on the dust removal layer 51, reducing the probability of it entering the air nozzle 6. On the other hand, the cleaning operation of the air nozzle 6 can be transferred to the easier-to-clean dust removal layer 51, reducing the cleaning difficulty and increasing the cleaning efficiency.

[0023] A cooling device for producing coated glass includes a production base 1, a cooling cavity 2 for conveying and cooling the coated glass, a conveying roller 3 in the cooling cavity 2, a refrigerator 4 mounted on the production base 1, the refrigerator 4 supplying cooling airflow into the cooling cavity 2, a dust removal device 5 for removing impurities mixed in the airflow at the bottom of the cooling cavity 2, and a plurality of air nozzles 6 for connecting to the refrigerator 4 at the top and bottom of the cooling cavity 2, and a groove in the bottom of the cooling cavity 2 into which the air nozzles 6 are embedded. The dust removal component 5 is disposed on the lower end of the jet nozzle 6. The dust removal component 5 includes a dust removal layer 51 installed on the cooling inner cavity 2. The dust removal layer 51 has a plurality of filter ports 52 adapted to the diameter of the jet nozzle 6. The filter ports 52 have a plurality of filter holes 53 for filtering the cooling airflow. Between adjacent filter ports 52, there are dust removal ports 54 with the same diameter and structure as the filter ports 52. The bottom plate of the cooling inner cavity 2 at the lower end of the dust removal port 54 is provided with a compensation column group 55 adapted to the dust removal port 54. The compensation column group 55 can be used to compensate and fill the filter ports 52, increasing the probability that dust is carried away from the interior of the dust removal layer 51.

[0024] The left and right ports of the cooling cavity 2 are equipped with rollers 56 for winding the dust removal layer 51, which serves to switch between the dust removal port 54 and the filter port 52. The height of the rollers 56 is less than the installation height of the conveyor rollers 3. The two rollers 56 rotate in different directions, causing the dust removal layer 51 to move back and forth during winding. This results in a change in the position of the filter port 52 and the dust removal port 54, from the filter port 52 being in contact with the air nozzle 6 to the dust removal port 54 being in contact with the air nozzle 6. At this time, the filter port 52 is placed on the compensating column assembly 55, which causes the compensating column assembly 55 to remove dust from the inside of the filter port 52. The bottom surface of the cooling cavity 2 is equipped with a removal plate 57 for removing dust from the dust removal port 54. The removal plate 57 has a gap at the installation position of the air nozzle 6 that matches its diameter. A telescopic rod 58 is installed between the removal plate 57 and the side wall of the cooling cavity 2. The telescopic rod 58 pushes the removal plate 57 to reciprocate on the dust removal layer 51. A through groove adapted to the structure of the removal plate 57 is opened on the side wall of the cooling cavity 2 away from the mounting surface of the removal plate 57. The through groove establishes a communication channel between the cooling cavity 2 and the outside world, so as to push the dust out of the cooling cavity 2 from the through groove. The reciprocating motion and the removal plate 57 at the upper end of the dust removal layer 51 are used to clean the dust covering the dust removal layer 51, reducing the probability of dust being carried to the coated glass by the airflow.

[0025] The compensation column assembly 55 includes an embedded groove 551 formed in the bottom plate of the cooling inner cavity 2. A chassis is installed in the embedded groove 551. A telescopic rod 58 connected to the chassis is installed on the embedded groove 551. Several straight rods 552 adapted to the filter port 52 are installed on the chassis. The extension length of the straight rods 552 on the chassis is equal to the opening thickness of the filter port 52. The diameter of the straight rods 552 is smaller than the diameter of the filter port 52, but the difference between them is compensated by a rubber layer sleeved on the straight rods 552. In the initial state, the compensation column assembly 55 does not contact the dust removal port 54 and will not hinder the winding of the dust removal layer 51.

[0026] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0027] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
