Description

Technical Field

[0001] The utility model relates to the technical field of polymer material processing, in particular to a vibrating screen used for processing plastic materials. Background Art

[0002] As one of the world's five major general-purpose engineering plastics, polyphenylene ether material is non-toxic, transparent, has a low relative density, has excellent mechanical strength, is heat-resistant, flame-retardant, has good dimensional stability, and has outstanding electrical insulation properties.

[0003] During the production process, vibrating screens are required to screen out qualified plastic particles. Qualified particles enter the finished product area and debris is removed. The vibrating screen can also screen out plastic particles of different sizes, thereby improving screening efficiency. However, conventional screening screens are integrated with the entire frame. Replacing the screen requires replacing the entire screen frame as well, resulting in a waste of screen frame resources. Utility Model Content

The eccentric wheel 5 is driven by the vibration motor 4 to rotate, thereby generating a vibration force, thereby realizing the screening of plastic particles. This technology is a well-known technology and will not be described in detail in this application.

[0031] See also Figure 1-3 The top of the motor support 3 is detachably mounted with a lower material tray 6 through a hoop assembly, the top of the lower material tray 6 is detachably mounted with a middle material tray 7 through a hoop assembly, the top of the middle material tray 7 is detachably mounted with a loading tray 8 through a hoop assembly, the top of the loading tray 8 is detachably mounted with a feed nozzle 9 through a hoop assembly, a conical tray 10 is fixedly mounted inside the lower material tray 6, and a discharge nozzle is fixedly mounted on one side of the lower material tray 6, the middle material tray 7 and the loading tray 8. When the entire vibrating screen is shaken, the plastic particles will be screened twice, and three plastic particles of different specifications will be screened out.

[0032] See also Figure 4-6 The inner walls of the middle material tray 7 and the upper material tray 8 are fixedly installed with a fixing ring 11, and a screen plate 12 is provided on the top of the fixing ring 11. Screen plates with different eyelets can be selected according to the situation, but the eyelets of the two screen plates 12 decrease from top to bottom; a C-type pressure ring 13 is provided on the top of the screen plate 12, which is used to press and fix the screen plate 12; the notch of the C-type pressure ring 13 is set toward the side of the discharge nozzle and will not block the discharge of plastic particles; the outer walls of the screen plate 12 and the C-type pressure ring 13 are provided with a slide groove 15, and the inner walls of the middle material tray 7 and the upper material tray 8 are fixedly installed with a slide bar 14 corresponding to the slide groove 15, which is used to ensure that the screen plate 12 and the C-type pressure ring 13 will not deflect due to vibration.

[0033] See also Figure 4-6A plug plate 16 is fixedly installed inside the C-shaped pressure ring 13, and a clamping head 17 is fixedly installed at the bottom of the plug plate 16. The plug plate 16 and the clamping head 17 are integrally formed and J-shaped. The screen plate 12 and the discharge tray 6 are both provided with slots 18 corresponding to the plug plate 16. The plug plate 16 is inserted into the slot 18, and the clamping head 17 at the bottom is just pressed against the bottom of the fixed ring 11. The C-shaped pressure ring 13 is clamped with the fixed ring 11 through the plug plate 16 and the clamping head 17.

[0034] See also Figure 7-9 The hoop assembly includes two symmetrically arranged hoop rings 19, the cross section of which is U-shaped. The hoop rings 19 are mounted on the outer flanges of the lower material tray 6, the middle material tray 7, the upper material tray 8 and the feed nozzle 9. One end of each of the two hoop rings 19 is fixedly mounted with a connecting block 1 20, the other end of the connecting block 1 20 is hinged to a connecting block 21, the other end of the connecting block 21 is hinged to a hinge seat 22, and the two hinge seats 22 are cross-hinged and movable. The two hoop rings 19 are hinged to each other through the connecting block 1 20, the connecting block 21 and the hinge seat 22. Here, because of the connecting block 1 20 and the connecting block 21, the movable space between the two hoop rings 19 is increased.

[0035] See also Figure 7-9 The other end of one of the hoop rings 19 is fixedly mounted with a curved bar 23, the outer wall of which is provided with a ratchet groove 24. The other end of the other hoop ring 19 is fixedly mounted with a mounting seat 25. A ratchet plate 27 is movably mounted inside the mounting seat 25 via a shaft 26. A torsion spring 28 is sleeved on the outer side of the shaft 26. The ratchet plate 27 is twisted by the torsion spring 28 and inserted into the ratchet groove 24. A handle 29 is fixedly mounted on the surface of the ratchet plate 27. When the curved bar 23 is pulled by a tool, the ratchet plate 27 slides while the ratchet groove 24 squeezes and tilts the ratchet plate 27. As the curved bar 23 is continuously pulled, the space between the two hoop rings 19 becomes tighter and tighter, thereby locking the upper and lower flanges. Conversely, the ratchet plate 27 can be pulled out by the handle 29. The ratchet plate 27 no longer restricts the ratchet groove 24, and the curved bar 23 can be pulled out, thereby removing the upper and lower flanges.

[0036] Working principle: When in use, the handle 29 is used to pull the ratchet plate 27 outward and rotate it, and the ratchet plate 27 is separated from the ratchet groove 24 on the surface of the curved bar 23, and then the curved bar 23 can be pulled out, thereby realizing the rotation and opening of the two hoop rings 19, so that the feed nozzle 9, the upper material tray 8 and the middle material tray 7 can be opened from top to bottom; then use a tool to press the clamping head 17 and tilt the insert plate 16, and then pull up the C-shaped pressure ring 13 to release the pressure on the screen plate 12, thereby achieving the purpose of convenient disassembly of the screen plate 12.

[0037] The screen plate 12 is movably installed on the surface of the fixed ring 11 through the slide bar 14, and the C-type pressure ring 13 is pressed on the surface of the screen plate 12 through the slide bar 14. At the same time, the plug 16 at the bottom of the C-type pressure ring 13 is inserted into the corresponding slot 18, and the clamp 17 is just pressed against the bottom of the fixed ring 11, so that the new screen plate 12 can be quickly installed; then the middle material tray 7, the upper material tray 8 and the feed nozzle 9 are stacked in this way, and then the hoop assembly is used to fix the three together, so as to achieve the purpose of convenient installation.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
