Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically to a surface cleaning device for sheet metal processing. Background Technology

[0002] Sheet metal parts undergo drilling and grinding processes during processing. During these processes, debris and exhaust fumes are easily generated. Some of these debris can affect the workshop environment, and in severe cases, they can even affect the health of the workers in the workshop. Most workshops use a unified exhaust system for ventilation, but this method is costly and complex to install. Therefore, it is necessary to develop a cleaning mechanism specifically designed for use on a single system. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a surface cleaning device for sheet metal processing, including a workbench for sheet metal processing. Several through holes are provided in the middle of the workbench. A cleaning mechanism is provided on the bottom surface of the workbench below the through holes. The cleaning mechanism includes a vacuum box, a filter box, a connecting box, and a baffle. The vacuum box is connected to the workbench, and one opening of the vacuum box covers the area where the through holes are located. The filter box and the connecting box are arranged in sequence and connected to each other below the vacuum box. The baffle is provided on the side of the workbench, and the area where the through holes are located is in the groove enclosed by the baffle. The chamber inside the baffle is connected to the vacuum box, and an inlet communicating with the chamber is provided on the end face of the baffle facing the through holes.

[0005] In this solution, a connecting box is used to connect to an external vacuum pumping mechanism, creating negative pressure inside the vacuum chamber. This negative pressure then suctions the processing area where the through-hole is located. Simultaneously, baffles around the processing area of ​​the through-hole also perform suction. This combined action significantly reduces the spread of debris, helps improve the quality of the workshop environment, and reduces harm to operators.

[0006] Furthermore, the chamber inside the baffle is connected to the opening formed on the side of the vacuum chamber through a pipe, and the opening on the top surface of the vacuum chamber covers the area where the through hole is located. The pipe connection helps to reduce costs and facilitates installation and assembly.

[0007] Furthermore, a first connection hole is provided on the top surface of the filter box, and it is threadedly connected to a first connection part at the bottom of the vacuum box through the first connection hole. A second connection hole is provided on the top surface of the connecting box, and it is threadedly connected to a second connection part at the bottom of the filter box through the second connection hole. The threaded connection structure facilitates quick assembly.

[0008] Furthermore, the filter box includes a box body and a filter screen. Insertion holes are arranged longitudinally at intervals on the side of the box body, and the filter screen is installed in the insertion holes in a pluggable manner. The pluggable installation of the filter screen facilitates cleaning.

[0009] Furthermore, a handle is provided at the end of the filter screen, and the handle is inserted into the corresponding hole to facilitate force application.

[0010] Furthermore, a fixing plate is provided on the baffle, and the fixing plate is connected to the operating table for easy assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model adds a cleaning mechanism to the bottom of the operating table to extract debris and exhaust gas generated during sheet metal processing, which helps improve the quality of the workshop environment, reduce injury to operators, and has a low cost.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 As shown, the surface cleaning device for sheet metal processing in this example includes a workbench 1 for sheet metal processing. Several through holes 3 are formed in the middle of the workbench 1. The area covered by the through holes is the processing area, where sheet metal parts are drilled, ground, and processed.

[0020] A cleaning mechanism 2 is installed on the bottom surface of the operating table 1 below the through hole 3. The cleaning mechanism 2 includes a vacuum box 21, a filter box 22, a connecting box 23, and a baffle 29. Figure 1As shown, the vacuum chamber 21 is cone-shaped, with a box opening formed at the top. The top box opening is fixed to the periphery of the plate processing area in the operating table 1 by bolts or the like. The top box opening of the vacuum chamber 21 is in contact with the bottom surface of the plate around the processing area, and the top box opening covers the processing area.

[0021] Below the vacuum chamber 21, a filter box 22 and a connecting box 23 are installed sequentially and connected in sequence. Figure 1 As shown, a filter box 22 is installed at the bottom of the vacuum box 21. A circular hole-shaped connecting hole 26 is formed on the top surface of the filter box 22, and a cylindrical connecting part 27 is formed on the bottom of the vacuum box 21. The filter box is fixed to the vacuum box by threaded connection between the connecting hole 26 and the connecting part 27.

[0022] Install the connecting box 23 at the bottom of the filter box 22, such as... Figure 1 As shown, a second connecting hole 32 is formed on the top surface of the connecting box 23, and a cylindrical connecting part 33 protrudes outward at the bottom of the filter box 22. The connecting hole 32 and the connecting part 33 at the bottom of the filter box 22 are threaded together to fix them as one unit. A third connecting hole 25 is formed at the bottom of the connecting box 23 to connect with external air extraction mechanisms, etc.

[0023] The operating table is rectangular in shape, with four baffles 29 fixed to the sides of the operating table 1. A fixing plate protrudes from one side of each baffle 29, and is secured to the operating table using bolts. The through-hole 3 is located within a groove formed by the four baffles 29. The upper part of the baffles 29 is higher than the operating table. The chambers within the baffles 29 are connected to the vacuum chamber 21 via pipes 28. Several inlets 30 communicating with the chamber are formed on the end face of the baffles 29 facing the through-hole 3. In this example, openings are formed on the four sides of the vacuum chamber 21 to connect with the pipes.

[0024] When in use, if the connecting hole three at the bottom of the connecting box is connected to an external air extraction mechanism, the debris and exhaust gas generated during the sheet metal processing are drawn in through the top opening of the vacuum box and the baffle inlet, filtered, and then extracted for direct discharge or further processing.

[0025] For a filter box, such as filter box 22, there are box body and filter screen 24. The side of the box body has longitudinally spaced insertion holes that communicate with the box body chamber. The filter screen 24 is inserted into the insertion holes to filter the airflow passing through the box body chamber. The plug-in structure makes it easy to replace the filter screen later.

[0026] A handle 31 can also be fixed at the end of the filter screen 24 to enlarge the opening of the insertion hole. The enlarged opening allows the handle to be inserted. When cleaning is required, force is applied to pull the handle out to remove the filter screen.

[0027] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
