Description

Technical Field

[0001] This utility model relates to the field of metal cutting equipment technology, and specifically to a high-efficiency dust removal and diversion device for metal cutting equipment. Background Technology

[0002] Metal cutting machines, also known as metal laser cutting machines, use the energy released when a laser beam is irradiated onto the surface of a metal workpiece to melt and evaporate the metal, thereby achieving the purpose of cutting or engraving. They are characterized by high precision, fast cutting speed, no limitation on cutting patterns, automatic layout to save materials, smooth cuts, and low processing costs.

[0003] Application number CN202120495122.8 discloses a high-efficiency dust removal device for cutting machines, which includes a cleaning component to promptly clean metal shavings and larger dust particles that have accumulated to a certain level at the bottom of the dust collector. This prevents them from affecting the internal environment of the dust collection chamber and thus its reusability, ensuring high-efficiency dust removal. However, the above design has shortcomings. The air inlet pipe has a simple structure and cannot pre-treat the dust generated during the operation of the metal cutting machine. Larger impurities in the dust directly enter the dust collection chamber, easily clogging the filter cartridge and affecting the working efficiency of the device.

[0004] Therefore, we propose a high-efficiency dust removal and diversion device for metal cutting equipment. Utility Model Content

[0005] The main purpose of this utility model is to provide a high-efficiency dust removal and diversion device for metal cutting equipment. Through the cooperation of adapter pipe, clamp, stud, and nut, a pretreatment hood can be easily installed at the end of the air inlet pipe away from the device body. The pretreatment hood is equipped with a first filter screen and a second filter screen. The first filter screen and the second filter screen can perform graded filtration of the smoke and dust generated by the metal cutting machine when it enters the pretreatment hood, filtering out large particulate impurities in the smoke and dust, which can improve the practicality of the device body and effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-efficiency dust removal and diversion device for metal cutting equipment includes a device body and an air inlet pipe. The air inlet pipe is fixedly connected to the upper part of one end of the device body. The end of the air inlet pipe away from the device body is connected to a pretreatment cover through a transfer pipe. A folded tube is sleeved on the end of the pretreatment cover away from the transfer pipe. A filter chamber is provided inside the pretreatment cover. The inner wall of the filter chamber is provided with a first assembly groove and a second assembly groove for installing a first filter screen and a second filter screen, respectively. A filter assembly is provided inside the filter chamber. The filter assembly includes a mounting base, a second filter screen, and a sealing gasket.

[0008] The adapter pipe is a horizontally arranged rectangular hollow structure. One end of the adapter pipe is fixedly connected to one end of the pretreatment cover. The end of the adapter pipe away from the pretreatment cover is sleeved on one end of the air inlet pipe. Both sides of the air inlet pipe are inserted with studs for limiting the position of the pretreatment cover. The end of the pretreatment cover near the studs is provided with a matching clip.

[0009] By adopting the above technical solution, and through the coordinated use of adapter pipes, clamps, studs, and nuts, it is easy to install a pretreatment hood at the end of the air inlet pipe away from the main body of the device. The pretreatment hood is equipped with a first filter screen and a second filter screen. The first filter screen and the second filter screen can perform graded filtration on the smoke and dust generated by the metal cutting machine when it enters the pretreatment hood, filtering out large particulate impurities in the smoke and dust, thereby achieving the purpose of pretreatment of the smoke and dust generated by the metal cutting machine when it is working.

[0010] Specifically, the stud and the clamp are provided in multiple sets. The end of the clamp away from the adapter tube is provided with a groove for the stud to pass through. One end of the stud passes through the clamp and is threadedly connected to the nut.

[0011] Specifically, the mounting base has a circular structure, is assembled in the second assembly groove, is snapped into the pretreatment cover, and has a second filter screen fixedly connected to the inner wall of the mounting base.

[0012] Specifically, the second filter screen is arranged parallel to the first filter screen, the first filter screen is fixedly connected to the pretreatment cover by a first stud, and the mounting base is fixedly connected to the pretreatment cover by a second stud.
