Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal painting technology, specifically a sheet metal painting device with air purification. Background Technology
[0002] Sheet metal processing is a metalworking technique that uses metal sheets such as steel, aluminum, and copper plates to create parts or components of various shapes and sizes through cutting, bending, stamping, and welding. Sheet metal products typically possess high precision, high strength, and complex shapes. During sheet metal processing, after a series of processing steps such as cutting and shaping, the semi-finished material needs to be painted. The painted material can then be used as a finished product in various applications. Existing technologies use enclosed paint spray booths to control paint mist diffusion, and the booth uses an exhaust system on the top or side walls to force out pollutants for purification. However, this method, being in a closed environment, suffers from poor paint mist flow and ineffective exhaust. Therefore, this application proposes a sheet metal painting device with air purification to address these issues. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] like Figure 1-4As shown, this utility model provides a technical solution: a sheet metal spraying device with air purification, including an operating table 1. Clamping plates 2 are provided at both ends of the upper side of the operating table 1. Rear support plates 3 are connected to the rear sides of both clamping plates 2, and the two rear support plates 3 slide within a rear sliding groove 4 opened on the rear side of the operating table 1. A lead screw structure is provided at the bottom end of the two rear support plates 3. The lead screw structure includes a lead screw, two threaded sleeves, and a drive motor, and is installed on the bottom side of the operating table 1. The two threaded sleeves are connected to the threads at both ends of the lead screw, with the threads at both ends arranged in opposite directions. The two threaded sleeves are installed at the bottom ends of the two rear support plates 3, and under the drive of the drive motor, the two threaded sleeves move closer or further apart. The sheet metal part is placed between the two clamping plates 2 by the rear support plate 3 driving the two clamping plates 2 to move closer or further apart. Under the drive of the screw structure, the two clamping plates 2 move closer to clamp and fix the sheet metal part. Two spray boxes 5 are arranged on the right side of the operating table 1, facing each other. The two spray boxes 5 are located on the upper and lower sides of the two clamping plates 2. The front ends of the two spray boxes 5 are connected to the front support plate 6. The front support plate 6 is divided into an inner slide plate and an outer slide plate, with the inner slide plate sliding on the top of the outer slide plate. The inner slide plate and the outer slide plate are respectively connected to the upper spray box 5 and the lower spray box 5. The front support plate 6 slides in the front slide groove 7 opened on the front side of the operating table 1. The bottom end of the front support plate 6 is provided with a screw structure. The system includes a lead screw, a threaded sleeve, and a drive motor, all mounted on the bottom side of the operating platform 1. The threaded sleeve is connected to the thread of the lead screw and is installed at the bottom of the front support plate 6. Driven by the drive motor, the threaded sleeve moves, which in turn drives the spray box 5 to move for painting operations via the front support plate 6. Each of the two vertically opposite spray boxes 5 has several spray nozzles 8 on its facing surfaces. Corresponding front air boxes 9 and rear air boxes 10 are located on the front and rear sides of the operating platform 1. The air outlet of the front air box 9 faces rearward, and the air inlet of the rear air box 10 faces forward. The air outlet of the front air box 9 corresponds to the air inlet of the rear air box 10. A purification box 11 is installed at the bottom of the rear air box 10, and an air outlet is located on the bottom side of the purification box 11. The purification box 11 is equipped with purification material 12, which consists of primary cotton and paint mist felt. Driven by the screw structure, the two spray boxes 5 are moved by the front support plate 6. When they correspond to the sheet metal parts, paint is supplied to the spray boxes 5 and sprayed through the nozzle 8. After spraying, it can be left to stand for a certain period of time. Then, the front air box 9 and the rear air box 10 are started. The wind speed is less than 2m / s. The oversprayed paint mist is directed into the rear air box 10 by the directional airflow. After the two-stage filtration of the purification box 11 (primary cotton intercepts large particles → paint mist felt adsorbs fine paint mist), the paint mist can be cleaned and purified quickly. At the same time, the coordinated convection design of the front air box 9 and the rear air box 10 can accelerate the painting on the sheet metal parts.
[0022] Side plates 13 are provided at both ends of the upper side of the operating table 1, and a sealing cover 14 is installed on the upper side of the rear air box 10. The side plates 13 and the sealing cover 14 can form an openable and closable sealed space. During operation, the operating area is closed. Through the coordinated convection design of the front air box 9 and the rear air box 10, a horizontal directional airflow field can be formed on the operating table 1. The paint mist is forced to be drawn into the rear air box 10, which can avoid stagnation in the sealed box and greatly improve the paint mist capture efficiency.
[0023] The operational steps for this application are as follows:
[0024] The sheet metal part is placed between two clamping plates 2. Driven by the screw structure, the two clamping plates 2 move closer to clamp and fix the sheet metal part. Then, the sealing cover 14 is put on to seal it. Driven by another screw structure, the two spray boxes 5 are moved by the front support plate 6. When they correspond to the sheet metal part, paint is supplied to the spray box 5 and sprayed through the nozzle 8. After the spraying is completed, the front air box 9 and the rear air box 10 are started. The paint mist is directed by the airflow into the rear air box 10 and filtered through the two-stage filtration of the purification box 11 (the primary cotton intercepts large particles and the paint mist felt adsorbs fine paint mist), which can quickly complete the cleaning and purification of the paint mist.
