Description

A food screening machine capable of screening seasoning particles of different particle sizes

Technical Field

The invention relates to the technical field of screening machines, in particular to a food screening machine capable of screening seasoning particles of different particle sizes.

Background technique

Condiments mainly refer to herbs and spices. Herbs are leaves of various plants, which can be fresh, air-dried or ground; spices are seeds, buds, fruits, flowers, bark and roots of plants. Condiments refer to supplementary foods that can increase the color, aroma and taste of dishes, promote appetite and are beneficial to human health; among them, Sichuan peppercorns are condiments. Before packaging, in order to make Sichuan peppercorns obtain higher profits, they need to be screened according to the diameter of the particles, so a screening machine is needed;

However, the existing screening machines cannot effectively screen the peppercorns according to the diameter of the particles, thereby reducing the quality of the peppercorns and further reducing the benefits of the peppercorns. At the same time, when screening, the existing screening machines will easily cause the mesh holes of the screening plates in the screening machines to be clogged by the peppercorn particles, thereby affecting the screening of the peppercorn particles and further reducing the working efficiency of the screening of the peppercorn particles.

Working principle: When the present invention is working, it includes the following steps:

Step 1: first place the peppercorns in the feed hopper 5, then start the servo motor 2, first control the output shaft of the servo motor 2 to rotate forward, and drive the connecting shaft 35 to rotate through the rotation of the output shaft of the servo motor 2, thereby driving the eccentric wheel 12 to rotate, and when the eccentric wheel 12 contacts the connecting block B21, the connecting block B21 will move downward, thereby driving the rectangular frame 42 to move downward, thereby driving the screening element A10 and the screening element B11 to move downward, and when the eccentric wheel 12 is separated from the connecting block B21, the connecting block B21 is reset under the spring rod 22, and then the eccentric wheel 12 contacts the connecting block B21 again, and then separates, thereby causing the screening element A10 and the screening element B11 to reciprocate up and down, avoiding the peppercorns and the mesh holes of the screening mesh plate A of the screening element A10 and the screening mesh plate B of the screening element B11 to be blocked, so as to facilitate the screening of the peppercorns;

Step 2: When the connecting block B21 reciprocates up and down, the bar-shaped tooth plate 401 will reciprocate up and down, thereby rotating the connecting gear 402, thereby rotating the driving shaft 403, further driving the bevel gear A407 to rotate, and the rotation of the bevel gear A407 drives the bevel gear B408 to rotate, and then drives the rotating shaft 406 to rotate, thereby driving the driving gear 405 to rotate, and the rotation of the driving gear 405 drives the driven gear 14 to rotate. When the discharge hole 40 on the driven gear 14 is aligned with the limit When the wide-mouth holes 27 on the plate 28 overlap, the peppercorns fall onto the spreading plate 31 through the feed pipe B. When the driven gear 14 rotates, the short shaft A29 is driven to rotate, thereby driving the cleaning rod 30 and the spreading plate 31 to rotate. The rotation of the cleaning rod 30 facilitates the peppercorns on the limit plate 28 to be pushed into the wide-mouth holes 27, thereby facilitating the falling of the peppercorns. The spreading plate 31 causes the peppercorns to fly out along the discharge trough 36, thereby facilitating the dispersion of the peppercorns on the surface of the screening member A10, thereby facilitating the screening of the peppercorns.

Step 3: After the peppercorns fall on the screening element A10, the peppercorns with large diameters remain on the screening element A10, while the peppercorns with medium diameters and small diameters pass through the mesh holes of the screening plate A of the screening element A10 and fall on the screening element B11, and then the peppercorns with medium diameters fall on the screening element B11, and then the peppercorns with small diameters pass through the mesh holes of the screening mesh plate B of the screening element B11 and fall on the bottom of the screening box 1, and then flow out through the discharge pipe at the bottom of the screening box 1;

Step 4: When the connecting shaft 35 rotates, the rotating disk 9 is driven to rotate, and then the short rod 8 is driven to rotate, thereby driving the connecting rod 19 to move up and down, and further driving the piston 18 to move up and down, and the gas in the collecting box 6 is pumped into the sealing cylinder, and then the gas enters the screening box 1 through the short tube B, so that the pepper shells and other impurities in the pepper are separated from the pepper. Since the gas in the collecting box 6 is pumped out, the pressure in the collecting box 6 is lower than the external pressure, so that suction is formed at the air inlet head, so that the pepper shells and other impurities are collected in the collecting box 6, and the quality of the pepper is further improved;

Step 5: When the screening is completed, the output shaft of the servo motor 2 is controlled to reverse, thereby driving the connecting shaft 35 to rotate in the opposite direction. Under the action of the reset spring 41, the arc-shaped movable block 38 and the arc-shaped fixed block 39 are engaged, thereby driving the disc 32 to rotate in the opposite direction, thereby driving the telescopic rod 33 to extend. When the telescopic rod 33 is extended, the disc 32 continues to rotate, which will drive the middle part of the screening element A10 and the screening element B11 to move upward, thereby tilting one end of the screening element A10 and the screening element B11; when the output shaft of the servo motor 2 is reversed by 140°, the controller 3 will control the servo motor 2 to stop working. At this time, the screening element A10 and the screening element B11 are in an inverted V shape, and then Finally, the peppers on the screening components A10 and B11 move along the guide plate 26 to the movable plate 25, and then flow into the discharge hopper 24 through the discharge opening, and finally flow out of the screening box 1 through the discharge hopper 24; when all the peppers have flowed out, the servo motor 2 is controlled to rotate forward, and the screening components A10 and B11 will be reset, so as to facilitate the screening of the peppers again; wherein, when the servo motor 2 rotates, the arc-shaped movable block 38 and the arc-shaped fixed block 39 will be in contact, and when the arc-shaped movable block 38 and the arc-shaped fixed block 39 are in contact, the arc-shaped movable block 38 will slide into the rectangular cavity, so that the ring 34 will not rotate with the connecting shaft 35, so as to facilitate the screening of the peppers.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
