Description

Technical Field

[0001] This utility model relates to the technical field of dual-track spraying production lines, and in particular to a dual-track spraying production line with a cleaning function. Background Technology

[0002] Spraying and coating refer to the application of protective or decorative layers to metal and non-metal surfaces. With the development of industrial technology, spraying and coating have evolved from manual processes to industrial automation, and the degree of automation is becoming increasingly higher. As a result, coating production lines are being used more and more widely.

[0003] Currently, when a dual-track spraying production line sprays workpieces, excess powder often remains on the edges and corners of the workpieces. In the subsequent conveying process, this powder adhering to the edges and corners is easily diffused into the air, thus polluting the internal environment of the production line. To effectively avoid such problems, cleaning devices such as brush blowing are usually used to clean the edges and corners of the workpieces after the spraying process is completed.

[0004] However, while traditional cleaning devices have a certain ability to clean edges and corners, they are prone to damaging the surface of workpieces during operation, which will undoubtedly have an adverse effect on the production quality of products. In addition, when the cleaning device cleans the edges and corners of workpieces, the conveying speed of the workpieces will be significantly reduced, thereby slowing down the overall production efficiency of products. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art where traditional cleaning devices reduce the conveying efficiency of workpieces and damage the workpiece surface when cleaning them. Therefore, this invention proposes a dual-track spraying production line with cleaning function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dual-track spraying production line with cleaning function includes a first conveying track and a second conveying track arranged in parallel and connected end to end. The first conveying track and the second conveying track are sequentially connected to the loading area, spraying area, drying area, spraying area, cleaning and recycling area, curing area and unloading area to form a production line.

[0008] It also includes: an isolation chamber, disposed on one side of the spraying area, wherein the first conveying track and the second conveying track pass through the isolation chamber and are disposed at the bottom of the isolation chamber;

[0009] A blower is installed in the isolation chamber at the lower end of the first and second conveying tracks. The isolation chamber is equipped with a dust suction unit, which works in conjunction with the blower to form a dust removal area inside the isolation chamber.

[0010] Furthermore, the dual-track spraying production line is alternately set with at least 4 spraying zones and 3 curing zones, and the dual-track spraying production line completes at least 4 spraying processes and 3 curing processes.

[0011] In order to remove powder that cannot adhere to the edges and surfaces of the workpiece without affecting the workpiece conveying efficiency, preferably, the blowing component includes a blower disposed on one side of the isolation chamber, the output end of the blower is fixedly connected to an air outlet pipe, wherein the end of the air outlet pipe away from the blower is connected to the inner cavity of the isolation chamber.

[0012] To further improve the cleaning quality of the workpiece, the air outlet end of the air duct is located at the lower end of the first and second conveying tracks.

[0013] For adsorbing and collecting powder inside the isolation chamber, preferably, the dust collection unit includes: an air inlet pipe fixedly connected to the top of the isolation chamber and communicating with the inner cavity of the isolation chamber, wherein the end of the air inlet pipe away from the isolation chamber is fixedly connected to a dust collection tank, and an exhaust fan is fixedly installed on the dust collection tank; a filter bag fixedly installed in the inner cavity of the dust collection tank, wherein the filter bag is located at the bottom of the exhaust fan, and the dust collection tank is provided with a back-blowing component for cleaning the filter bag.

[0014] In order to efficiently clean the filter bags and improve the dust removal effect, the back-blowing component further includes a compressed air tank fixedly installed on the dust collection tank, the output end of the compressed air tank is fixedly connected to the air blowing pipe, and a pulse valve is fixedly sleeved on the output end of the compressed air tank.

[0015] To further improve the cleaning effect of the back-blowing component, the end of the air blowing pipe away from the compressed air tank extends into the dust collection tank and is located between the filter bag and the exhaust fan.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] A dual-track spraying production line with a cleaning function is disclosed. All parts of the device not described herein are identical to or can be implemented using existing technologies. This utility model's dual-track spraying production line alternately sets at least four spraying zones and three curing zones, ensuring uniform and smooth spraying with no interference between the front and back spraying. Through the setting of an isolation chamber, after the workpiece is sprayed and enters the isolation chamber, an upward airflow is used to blow off loosely adhered powder from the edges and surfaces of the workpiece, preventing powder from flying and polluting the internal environment of the production line during transport. Furthermore, the dust removal unit extracts and stores the powder inside the isolation chamber, preventing powder leakage.

[0018] This dual-track spraying production line with cleaning function, through the setting of the blowing component, since the air outlet of the air pipe is located at the lower end of the first and second conveying tracks, makes the conveyed workpiece perpendicular to the airflow blown out by the air outlet. At this time, the airflow flows from bottom to top, which can blow off the powder that is not firmly adhered to the edges and surfaces of the workpiece, and avoid the powder splashing during the process of the workpiece entering the curing zone from the spraying zone, which would cause pollution to the internal environment of the production line.

[0019] This dual-track spraying production line with cleaning function, through the setting of the dust collection unit, when the blower cleans the powder, the dust collection unit draws air downward, so that a stable dust removal area is formed inside the isolation chamber. When the powder spreads inside the isolation chamber, the dust collection unit extracts the powder, which can prevent the powder from leaking out and causing pollution to the isolation chamber.

[0020] This dual-track spraying production line with cleaning function uses a back-flushing component to automatically open the pulse valve after the internal pressure of the compressed air tank reaches a preset value. The airflow impacts the filter bag, which can efficiently clean the filter bag and improve its filtration quality. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0028] Reference Figures 1-3A dual-track spraying production line with cleaning function includes a first conveying track 11 and a second conveying track 12 arranged in parallel and connected end to end. The first conveying track and the second conveying track are connected in sequence to the loading area 13, the spraying area 14, the spraying area 15, the drying area, the cleaning and recycling area, the curing area 16, and the unloading area 18 to form a production line.

[0029] It also includes: an isolation chamber 1, which is located on one side of the spraying area; a first conveying track 11 and a second conveying track 12 passing through the isolation chamber 1 and located at the bottom of the isolation chamber 1; a blower, which is located at the lower end of the first conveying track 11 and the second conveying track 12 in the isolation chamber 1; a dust collection part is provided on the isolation chamber 1, and the dust collection part and the blower work together to form a relatively stable dust removal area inside the isolation chamber 1.

[0030] Furthermore, the dual-track spraying production line alternately has at least 4 spraying zones and 3 curing zones, and completes at least 4 spraying processes and 3 curing processes. Specifically, the number of isolation chambers 1 can be set according to the number of spraying zones, and each isolation chamber 1 is located at the exit of the spraying zone.

[0031] The dual-track spraying production line of this utility model has at least 4 spraying zones and 3 curing zones alternately. The spraying is uniform and flat, and the spraying of the front and back sides does not interfere with each other. With the setting of the isolation chamber 1, after the workpiece is sprayed and enters the isolation chamber 1, the blower blows upward to blow off the powder that is not firmly attached to the edges and surface of the workpiece, so as to avoid the powder flying and polluting the internal environment of the production line during the conveying process. In addition, the dust removal unit extracts and stores the powder inside the isolation chamber 1 to prevent powder leakage.

[0032] In this preferred embodiment, the blowing device includes a blower 2 disposed on one side of the isolation chamber 1. The output end of the blower 2 is fixedly connected to an air outlet pipe 21. The end of the air outlet pipe 21 away from the blower 2 is connected to the inner cavity of the isolation chamber 1. The air outlet end of the air outlet pipe 21 is located at the lower end of the first conveying track and the second conveying track.

[0033] Specifically, by setting up the blower, since the air outlet of the air outlet pipe 21 is located at the lower end of the first and second conveying tracks, the conveyed workpiece is perpendicular to the airflow blown out by the air outlet pipe 21. At this time, the airflow flows from bottom to top, which can blow off the powder that is not firmly adhered to the edges and surfaces of the workpiece, and avoid the powder splashing during the process of the workpiece entering the curing zone from the spraying zone, which would cause pollution to the internal environment of the production line.

[0034] In this preferred embodiment, the dust collection unit includes: an air inlet pipe 3, which is fixedly connected to the top of the isolation chamber 1 and communicates with the inner cavity of the isolation chamber 1. The end of the air inlet pipe 3 away from the isolation chamber 1 is fixedly connected to a dust collection tank 31, and an exhaust fan 32 is fixedly installed on the dust collection tank 31; a filter bag 33 is fixedly installed in the inner cavity of the dust collection tank 31, the filter bag 33 is located at the bottom of the exhaust fan 32, and the dust collection tank 31 is provided with a back-blowing component for cleaning the filter bag 33.

[0035] Specifically, by setting up the dust collection unit, when the blower cleans the powder, the dust collection unit draws air downwards, so that a stable dust removal area is formed inside the isolation chamber 1. When the powder spreads inside the isolation chamber 1, the dust collection unit will extract the powder, which can prevent the powder from leaking out and causing pollution to the isolation chamber 1.

[0036] Furthermore, the back-blowing component includes a compressed air tank 4 fixedly installed on the dust collection tank 31. The output end of the compressed air tank 4 is fixedly connected to a blowing pipe 41. A pulse valve 42 is fixedly sleeved on the output end of the compressed air tank 4. The end of the blowing pipe 41 away from the compressed air tank 4 passes through the dust collection tank 31 and is located between the filter bag 33 and the exhaust fan 32.

[0037] Specifically, by setting up the backflush mechanism, after the internal pressure of the compressed air tank 4 reaches the preset value, the pulse valve 42 automatically opens, using airflow to impact the filter bag 33, which can efficiently clean the filter bag 33, thereby improving its filtration quality.

[0038] The working principle of this utility model:

[0039] During the spraying process, the workpiece is mounted on the first conveyor track 11 and the second conveyor track 12 in the loading area. Then, the workpiece is transported to the spraying area for alkaline washing, water washing, and draining. After the workpiece is processed, it is transported to the drying area for heating and drying. Then, it enters the spraying area for spraying. The sprayed workpiece leaves the spraying area and enters the isolation chamber 1. At this time, the blower 2 drives the air outlet pipe 21 to blow air upward, which can clean the edges and corners of the workpiece and the loosely attached powder. Then, the air inlet pipe 3 draws air into the isolation chamber 1, so that the isolation chamber 1 forms a stable dust removal area. After the powder enters the dust collection tank 31 through the air inlet pipe 3, the filter bag 33 can effectively isolate the powder.

[0040] During the processing, the workpiece needs to be sprayed repeatedly. An isolation chamber 1 is set at the exit of each spraying area to efficiently clean the workpiece and prevent powder from flying during the transportation process and polluting the internal environment of the production line.

[0041] During use, a large amount of powder will adhere to the surface of the filter bag 33 inside the vacuum unit, affecting the vacuuming effect. After the compressed air tank 4 compresses the gas to reach the specified pressure, the pulse valve 42 automatically opens and uses the airflow backflow to remove the powder from the surface of the filter bag 33, thereby improving the vacuuming quality and maintenance efficiency of the vacuum unit.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
