[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] Example 1: A user-friendly powder sieving machine, see [link to example]. Figures 1 to 4 The system includes a frame 1, a gantry frame 2, a feeding channel 3, a screening structure 5, a discharge channel 6, and a collection box 7. The gantry frame 2 is fixed to one end of the top of the frame 1. The feeding channel 3 is fixed to the gantry frame 2. The screening structure 5 is arranged on the frame 1. The discharge channel 6 is fixed inside the frame 1. The collection box 7 is arranged at the discharge end of the discharge channel 6.

[0037] The screening structure 5 includes a frame 501, an outer frame 507, and a screen frame 508.

[0038] Frame 501 is fixed to the machine frame 1; outer frame 507 is movably disposed within frame 501; screen frame 508 is arranged within outer frame 507; the mesh size of screen frame 508 is selected and used by the technical personnel of this profession according to the actual situation; wherein, connecting rods B5010 are fixedly provided at one end of each side of outer frame 507, and sliders 506 are slidably disposed in sliding holes 5011 opened on both sides of frame 501, and sliders 506 are connected to the outer ends of connecting rods B5010. A connecting rod A505 is fixedly provided at the outer end of the frame 501; a pulley 502 is rotatably provided at one end of the frame 501. The pulley 502 is connected to the drive wheel of the motor body 4 fixed in the frame 1 via belt drive. A cam arm 503 is fixedly provided on the outer side of the pulley 502. The cam arm 503 is connected to the outer end of the connecting rod A505 via a connecting arm 504. The two ends of the connecting arm 504 are rotatably connected to the outer ends of the cam arm 503 and the connecting rod A505 via rotating shafts, respectively.

[0039] This utility model, by setting up a frame 501, an outer frame 507, a screen frame 508, a connecting rod B5010, a sliding hole 5011, a slider 506, a connecting rod A505, a cam arm 503, and a connecting arm 504, has the advantage of laterally moving the screen frame 508, so that the powder on the screen frame 508 moves laterally for screening, reducing splashing. It solves the problem that when the vibrating motor drives the screen to vibrate, the screen will vibrate and fluctuate, which will easily cause the powder to splash out.

[0040] Specifically, the screen frame 508 always corresponds to the discharge end of the feed channel 3 and the feed end of the discharge channel 6; the screen frame 508 can always receive and discharge materials.

[0041] Furthermore, the screen frame 508 is inserted inside the outer frame 507; wherein, a limiting frame strip 509 is fixedly provided at the bottom end of the outer frame 507, and the limiting frame strip 509 is supported and engaged with the bottom end of the screen frame 508. The screen frame 508 is detachable, which facilitates the cleaning of residual particles on the screen frame 508.

[0042] Furthermore, grooves 5071 are respectively provided on both sides of the inner wall of the outer frame 507, and abutment springs 5072 are arranged in the grooves 5071. Slots 5081 are respectively provided on both sides of the screen frame 508, and the abutment springs 5072 abut against the slots 5081. The abutment springs 5072 have an arc-shaped structure, and the arched end of the abutment springs 5072 is adapted to the slots 5081.

[0043] This utility model, by setting a groove 5071, an abutment spring 5072, and a slot 5081, has the advantage that after the screen frame 508 is embedded in the outer frame 507, the abutment spring 5072 and the slot 5081 further position the screen frame 508.

[0044] Working principle: Using the device of this utility model, the drive wheel of the motor body 4 rotates, driving the pulley 502 to rotate. The cam arm 503 performs circular motion. Under the drive of the connecting arm 504, the connecting rod A505 moves laterally, driving the slider 506 to reciprocate along the sliding hole 5011, thereby driving the outer frame 507 and the screen frame 508 to reciprocate. Rice flour enters through the feed channel 3 and falls onto the reciprocating screen frame 508 for screening. The screened rice flour is discharged from the discharge channel 6 into the collection box 7. The screen frame 508 can be lifted upwards, and the arched end of the contact spring 5072 leaves the slot 5081. The screen frame 508 can be removed to clean the residual particles, and then the screen frame 508 can be inserted into the outer frame 507.
