Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder screening devices, in particular to a screen fixing structure for a metal powder screening device. Background Art
[0002] Screening device is a mechanical equipment that uses rotation, vibration, reciprocation, shaking and other actions to screen various raw materials and primary products into several grades according to the particle size of the materials, or remove large particles of impurities, and then carry out the next step of processing and improve product quality. Screening machine is a kind of equipment widely used to separate bulk materials into two or more particle size grades.
[0003] At present, common screening machines usually adopt a design in which a screen is installed on the upper end, and the screen is used to screen materials of different particle sizes. The screen is directly fixed to the screening machine by springs. Although this structure has high powder screening efficiency, the screen and the screening machine body are an integrated structure and cannot be disassembled. When raw materials of different particle sizes need to be screened, the specifications of the screen cannot be replaced or adjusted, which cannot meet the needs of the staff. Utility Model Content
[0004] The utility model aims to solve the above problem and provides a screen fixing structure for a metal powder screening device.
[0005] The utility model is realized through the following technical scheme: a screen fixing structure for a metal powder screening device, characterized in that it includes a fixed base, a group of springs are provided on the top of the fixed base, a connecting plate is provided on the top of the spring, support bases are provided on both sides of the connecting plate, a rotating shaft is provided between the two supporting bases, a hook is provided on the rotating shaft, and the hook is sleeved on the rotating shaft.
[0006] Furthermore, a fixing hole is provided on the fixing seat, and the fixing seat is installed on the powder screening device by means of bolts passing through the fixing hole.
[0007] Furthermore, the hook is hung on the outer wall of the screen.
[0008] Furthermore, there are two springs, and the upper and lower ends of each spring are respectively welded to a fixed base and a connecting plate.
[0009] The beneficial effects of the utility model are as follows: the utility model can better fix the screen by adopting a hook design, that is, one end of the utility model is fixed on the screening machine body, and the other end is hung on the screen by a hook; the utility model is adopted to connect the screening machine and the screen, so that the later staff can quickly replace the screen when they need to screen raw materials of different particle sizes, which is convenient to operate and has strong practicality.

[0014] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with embodiments.
[0015] like Figures 1 to 3 As shown, a screen fixing structure for a metal powder screening device includes a fixing base 1, a fixing hole 2 is provided on the fixing base, and the fixing base is installed on the powder screening device by bolts passing through the fixing hole 2. A group of springs 3 are provided on the top of the fixing base 1, and there are two springs 3. The upper and lower ends of each spring 3 are respectively welded to the fixing base 1 and the connecting plate 4.
[0016] A connecting plate 4 is provided on the top of the spring 3, and supporting bases 5 are provided on both sides of the connecting plate 4. A rotating shaft 6 is provided between the two supporting bases 5, and a hook 7 is provided on the rotating shaft 6. The hook 7 is sleeved on the rotating shaft 6, and the hook 7 is hung on the outer wall of the screen.
[0017] When in use, the device is fixed to the screening machine body by means of bolts passing through the fixing holes 2, and then the screen is installed above the screening machine body. The device is pulled to pull the rotating shaft 6 to hang the hook 7 on the outer wall of the screen, and the screen is fixed by means of the elastic force of the spring 3. When the screen needs to be replaced, the hook 7 is pulled again to remove the fixation of the hook 7 to the screen, and then the screen can be replaced.
[0018] Except for the technical features described in the specification, the other technical features are known to those skilled in the art.
