The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0024] Example 1:
[0025] A preferred embodiment of the milk powder raw material screening equipment provided by this utility model is, for example... Figure 1-5 As shown: A milk powder raw material screening device includes a base 1, pads 2 are fixedly installed at equal intervals on both sides of the bottom of the base 1, a collection box 3 is set on the top of the base 1, a screening angle adjustment component 4 is set on one side of the top of the base 1, and a swing adjustment component 5 is set on the other side of the top of the base 1.
[0026] The screening angle adjustment component 4 specifically includes: a side plate 411, which is fixedly installed at equal intervals on the top of the base 1; a cross groove 412, which is formed on the surface of the side plate 411; and a clamping slider 413, which is slidably connected to the inner wall of the cross groove 412.
[0027] A pulley 414 is movably installed between the inner walls of the clamping slider 413. The surface of the pulley 414 is slidably connected to the inner wall of the cross groove 412. L-shaped side plates 415 are fixedly installed on both sides of the clamping slider 413. A spring 416 is fixedly installed between one side of the L-shaped side plate 415 and the inner wall of the cross groove 412. A connecting rod 417 is fixedly installed on the surface of the clamping slider 413.
[0028] A screening frame 418 is fixedly installed between the inner sides of the connecting rod 417. Adjustment grooves 419 are provided at equal intervals on both sides of the screening frame 418. Rotating rods 4111 are fixedly installed at equal intervals on both sides of the inner wall of the screening frame 418. A concave frame 4112 is rotatably connected to the other end of the rotating rod 4111.
[0029] A threaded rod 4113 is slidably connected to the inner wall of the adjusting chute 419. One end of the threaded rod 4113 extends into the interior of the screening frame 418 and is fixedly connected to the surface of the concave frame 4112. The other end of the threaded rod 4113 extends out of the screening frame 418. A fastening sleeve 4114 is threadedly connected to the outer wall of the threaded rod 4113. The surface of the fastening sleeve 4114 is in contact with the surface of the screening frame 418. A screen 4115 is fixedly installed between the inner walls of the concave frame 4112. A discharge plate 4116 is fixedly installed between the inner walls of the concave frame 4112. The surface of the discharge plate 4116 is in contact with the surface of the concave frame 4112.
[0030] In this example, the screening angle can be adjusted by setting the screening angle adjustment component 4. First, rotate the fastening sleeve 4114 to loosen the fastening of the threaded rod 4113 and the screening frame 418. Then, push the concave frame 4112 upward and rotate the threaded rod 4113 along the adjustment groove 419. After adjusting to the desired position, rotate the fastening sleeve 4114 to tighten it against the screening frame 418 to ensure the stability of the threaded rod 4113, thereby achieving the adjustment of the screening angle.
[0031] Example 2:
[0032] Based on Example 1, a preferred embodiment of the milk powder raw material screening equipment provided by this utility model is as follows: Figure 1-5 As shown: The swing adjustment assembly 5 specifically includes: a fixed block 511, which is equidistantly fixedly installed on the bottom of the inner wall of the screening frame 418; an L-shaped support 512, which is fixedly installed on the top side of the base 1; and a push rod 5112, which is movably connected between the fixed blocks 511.
[0033] A servo motor 513 is fixedly mounted on the surface of the L-shaped support 512. A rotating shaft is fixedly mounted on the output end of the servo motor 513. The other end of the rotating shaft movably passes through the surface of the L-shaped support 512 and extends to one side of the L-shaped support 512. A turntable 514 is fixedly connected to the other end of the rotating shaft. A groove 515 is opened on the surface of the turntable 514. A perforated plate 516 is fixedly installed between the inner walls of the groove 515.
[0034] An adjusting screw 517 is rotatably connected between the inner walls of the perforated plate 516. One end of the adjusting screw 517 extends to the top of the turntable 514, and a knob 518 is fixedly connected to one end of the adjusting screw 517. The other end of the adjusting screw 517 extends to the bottom of the inner wall of the slide groove 515. A T-shaped threaded block 519 is threadedly connected to the outer wall of the adjusting screw 517. A connecting plate 5111 is fixedly installed on the surface of the T-shaped threaded block 519. The surface of the connecting plate 5111 is movably connected to the other end of the push rod 5112.
[0035] In this example, the swing amplitude can be adjusted by setting the swing adjustment component 5. When it is necessary to increase the swing amplitude, the operator rotates the knob 518 to drive the adjusting screw 517 to rotate. The rotation of the adjusting screw 517 causes the T-shaped threaded block 519 to move upward. The T-shaped threaded block 519 finally drives the connecting plate 5111 to move together. The rising of the connecting plate 5111 drives one end of the push rod 5112 to be raised in height. During the rotation of the turntable 514, the diameter of the circumference of one end of the push rod 5112 will increase, thereby increasing the swing amplitude and achieving the swing adjustment effect.
[0036] Working principle: First, the swing amplitude can be adjusted by setting the swing adjustment component 5. Raw materials are placed on the screen 4115, and the servo motor 513 is started to drive the turntable 514 and connecting plate 5111 to rotate. The connecting plate 5111 rotates in a circular motion, and through the push rod 5112 and the fixed block 511, it drives the screening frame 418 to swing back and forth. The two-layer screen 4115 can screen raw materials of different sizes. The top screen 4115 is a coarse screen, while the bottom screen is a fine screen. Materials that do not meet the aperture of the screen 4115 are discharged directly through the discharge plate 4116. Following the discharge, the raw material falling through the screen 4115 can be collected through the collection box 3, achieving multi-layer screening. The screening frame 418 slides within the cross groove 412 via the connecting rod 417, clamping slider 413, and pulley 414. During the sliding process, the spring 416 can increase the shaking frequency of the screening frame 418, thereby improving screening efficiency. For larger and harder raw materials, the shaking force can be appropriately increased to allow larger particles to pass through the screen 4115 more quickly, avoiding clogging of the screen holes and improving screening efficiency. For smaller, lighter, or easily agglomerated particles... Reducing the swaying force of the raw materials can prevent small particles from being excessively scattered and difficult to pass through the screen 4115, while avoiding losses and pollution caused by flying light particles, ensuring the accuracy of screening. When it is necessary to increase the swaying amplitude, the operator rotates the knob 518 to drive the adjusting screw 517 to rotate. The rotation of the adjusting screw 517 causes the T-shaped threaded block 519 to move upward. The T-shaped threaded block 519 finally drives the connecting plate 5111 to move. The rising of the connecting plate 5111 drives one end of the push rod 5112 to be raised to a higher height. During the rotation of the turntable 514, the push rod 5112 is pushed upward. The diameter of the circumferential rotation at one end of rod 5112 will increase, increasing the swing amplitude. When it is necessary to adjust the screening angle, first rotate the fastening sleeve 4114 to loosen the fastening of the threaded rod 4113 and the screening frame 418. Then push the concave frame 4112 upward and rotate it along the adjusting groove 419 through the threaded rod 4113. After adjusting to the desired position, rotate the fastening sleeve 4114 to tighten it against the screening frame 418 to ensure the stability of the threaded rod 4113, thereby achieving the functions of screening angle adjustment and swing adjustment.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
