Description

Technical Field

Traditional screening devices have some shortcomings that may limit production efficiency and product quality.

[0003] Difficulty in grading different particle sizes: Traditional glass powder screening devices often have certain difficulties in grading different particle sizes. Since the aperture of the screening disc is difficult to design fine enough and cross-mixing is prone to occur during the screening process, the particle size distribution is not uniform, which affects the quality of the final product.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0053] See also Figure 1-6 , a multi-stage screening device for glass powder:

[0054] It includes a screening machine chamber 1 and a bottom chassis 2, and a multi-stage screening mechanism 3 is arranged inside the screening machine chamber 1;

[0055] The multi-stage screening mechanism 3 includes:

[0056] Five screening discs 31 are distributed in an equidistant order from top to bottom;

[0057] 5 pairs of side positioning frames 32 are arranged in order and parallel from top to bottom, and 5 screening discs 31 are correspondingly overlapped between the 5 pairs of side positioning frames 32, which can be pulled out one by one after the classification and screening operation is completed, which is more convenient for the subsequent classification and collection operation;

[0058] A swing screening transmission mechanism 33 distributed on the outside of five side positioning frames 32 on both sides;

[0059] A drive assembly 34 distributed inside the bottom chassis 2 and with its output end connected to the bottom of the left swing screening transmission mechanism 33;

[0060] The swing screening transmission mechanism 33 specifically includes:

[0061] Rotate the rotary seats 331 respectively installed on the upper and lower walls of the screening machine bin 1;

[0062] A driving column 332 mounted at the edge between the upper and lower rotating seats 331;

[0063] A transmission column 333 connected to the outer sides of five side positioning frames 32 on the same side;

[0064] Five hinged transmission members 334 connected between the driving column 332 and the transmission column 333;

[0065] A linear guide assembly 335 mounted on the upper and lower walls of the screening machine chamber 1 and connected to the upper and lower ends of the transmission column 333;

[0066] Among them, the rotating seat 331 can drive the driving column 332 to make uniform circular motion around its center as a whole, and then drive the driving column 333 to move through 5 articulated transmission parts 334. During this period, the linear guide assembly 335 can limit the driving column 333 to only make left and right linear motion, thereby driving the side positioning frames 32 on both sides to make rapid left and right swinging motion, thereby realizing the synchronous swinging screening drive operation of the 5 screening discs 31.

[0067] The articulated transmission member 334 comprises:

[0068] Rotate the sleeve 3341 sleeved on the driving column 332;

[0069] An articulated seat 3342 mounted on the transmission column 333;

[0070] A connecting rod 3343 connected to the sleeve tube 3341 and the hinged end of the hinge seat 3342;

[0071] The linear guide assembly 335 includes:

[0072] a horizontally distributed guide column 3351;

[0073] A guide sleeve 3352 slidably sleeved on the guide column 3351, and the guide sleeve 3352 is fixedly connected to one end on the same side of the transmission column 333;

[0074] When the driving column 332 performs circular rotational motion, the articulated transmission member 334 cooperates with the linear guide assembly 335 to convert its circular motion into a motion that drives the driving columns 333 on both sides to swing back and forth, thereby realizing the swing screening operation of the screening disc 31.

[0075] The drive assembly 34 includes:

[0076] A drive shaft 341 connected to the bottom center of the rotating seat 331 in the left swing screening transmission mechanism 33;

[0077] A transmission gear 342 connected to the bottom end of the driving shaft 341;

[0078] A driving gear 343 meshed with the right side of the transmission gear 342;

[0079] A driving motor 344 drives the driving gear 343 to rotate.

[0080] The transmission ratio between the driving gear 343 and the transmission gear 342 is set to 1:1;

[0081] The driving motor 344 drives the driving gear 343 to rotate, and then drives the transmission gear 342 meshing with it to rotate synchronously, and finally drives the side rotating seat 331 to rotate quickly through the driving shaft 341, so as to start the operation of the side swing screening transmission mechanism 33, and the swing screening transmission mechanism 33 on the other side will start accordingly.

[0082] The sieve apertures of the five sieve discs 31 decrease in order from top to bottom, thereby enabling graded and continuous sieving operations.

[0083] A closed door 12 is provided on the front of the screening machine chamber 1 .

[0084] A control panel 11 is provided on the right side of the front of the screening machine chamber 1 .

[0085] A feed hopper 4 is provided on the top of the screening machine chamber 1 .

[0086] The working process of the device is as follows:

[0087] Device preparation: Put the glass powder to be screened evenly into the screening machine chamber 1 through the top feeding hopper 4.

[0088] Start operation: The operator controls the drive motor 344 to start through the control panel 11. The rotation of the motor causes the synchronous rotation of the drive shaft 341, the transmission gear 342, and the drive gear 343, and finally causes the rotating seat 331 of the left swing screening transmission mechanism 33 to rotate rapidly.

[0089] Swing screening action: The rotation of the left rotating seat 331 drives the driving column 332 to perform circular motion. The combination of the articulated transmission member 334 and the linear guide assembly 335 converts the circular motion into the left and right reciprocating swinging motion of the transmission columns 333 on both sides. Such swinging motion acts on the side positioning frame 32, thereby driving the five screening discs 31 to perform synchronous left and right rapid swinging screening operations.

[0090] Screening process: The glass powder is screened from top to bottom in order, and glass powders of different particle sizes are classified and retained in different screening plates 31 .

[0091] Grading collection: After the grading and screening operation is completed, the operator turns off the drive motor 344 through the control panel 11, then opens the closed door 12 on the front side, and then pulls out the screening plates 31 placed between the side positioning frames 32 one by one to perform the classification and mobile phone operation.

[0092] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
