Description

Technical Field

[0001] The utility model relates to the technical field of production and processing equipment, in particular to a screening machine for starch production. Background Art

[0002] Screening machines are key to the starch production chain, playing a decisive role in improving the quality of raw materials to final products, production efficiency, cost control, and food safety.

[0003] In the prior art, for example, Chinese patent number CN219482869U, “Screening machine for starch production”, comprises a screening box, a feed hopper is fixedly mounted above the screening box, a conveying box is fixedly mounted inside the feed hopper, a front end, a rear end and both sides of the conveying box are provided with feed ports, a conveying rod is rotatably mounted inside the conveying box, and the conveying rod passes into the interior of the screening box, a material guide pipe is fixedly mounted inside the screening box along the outer side of the conveying rod, a spiral blade is fixedly mounted on the outer side of the conveying rod, and a crushing piece is fixedly mounted on the outer side of the conveying rod below the spiral blade.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that the starch is screened by a sieve plate. However, the moisture of the newly produced starch is very high, and such starch can easily clog the sieve plate, reducing the efficiency of the sieve plate. At the same time, because the vibration motor cannot contact the blocked part of the sieve plate, the vibration motor cannot clean the sieve plate in time and effectively, which aggravates the blockage of the sieve plate and further reduces the work efficiency.

[0026] like Figure 1 -5, the inner surface of the shell 1 is provided with two limit grooves 21, the inner surfaces of the two limit grooves 21 are movably embedded with limit columns 20, the outer surfaces of the two limit columns 20 are fixedly connected with fixed plates 15, and the outer surfaces of the opposite sides of the two fixed plates 15 are fixedly connected with a plurality of bristles 16, the bristles 16 can contact with the rotating screening drum 10 in time and clean the blocked holes, thereby further preventing the screening drum 10 from being blocked and improving the working efficiency.

[0027] like Figure 1 -5, the buffer mechanism includes a plurality of springs 17, and the plurality of springs 17 are evenly divided into two groups. The outer surfaces of the two groups of springs 17 are fixedly connected with support plates 19, and the two support plates 19 are fixedly connected to the outer surface of the shell 1. The two groups of springs 17 are fixedly connected to the outer surfaces of the two limit blocks 11, and the two limit blocks 11 are movably embedded in the inner surfaces of the two support plates 19. The springs 17 can buffer the longitudinal vibration of the rotating shaft 8.

[0028] like Figure 1-5, the outer surface of the rotating shaft 4 is movably sleeved with two fixed blocks 18, and the two fixed blocks 18 are fixedly connected to the outer surface of the shell 1. The telescopic mechanism includes a plurality of telescopic rods 23, and the outer surfaces of the plurality of telescopic rods 23 are movably sleeved with springs 24, and the tops of the plurality of telescopic rods 23 are fixedly connected with arc blocks 25, and the outer surfaces of the two pulleys 27 are provided with a plurality of working grooves 22, and the plurality of springs 24 are fixedly connected to the inner surfaces of the plurality of arc blocks 25, and the plurality of springs 24 are fixedly connected to the inner walls of the plurality of working grooves 22, and the plurality of telescopic rods 23 are movably embedded in the inner surfaces of the plurality of working grooves 22.

[0029] like Figure 1 -5, the feeding mechanism includes two slide bars 13, the two slide bars 13 are movably embedded in the inner surfaces of the two slide grooves 12, and the outer surfaces of the two slide bars 13 are fixedly connected with the hopper 14. The cooperation between the slide grooves 12 and the slide bars 13 can prevent the hopper 14 from rotating when the screening drum 10 rotates, thereby providing a good working environment for the hopper 14.

[0030] like Figure 1 -5, two fixing plates 15 are fixedly connected to the outer surface of the hopper 14, and the fixing plates 15 can provide a good working environment for the bristles 16, so that the bristles 16 can clean the screening drum 10 in time.

[0031] Working principle: This equipment is a screening machine for starch production. When in use, starch is introduced into the hopper 14, and then the motor 3 on the support plate 2 is started. The motor 3 drives the rotating shaft 4 on the two fixed blocks 18 to rotate through the output shaft. The rotating shaft 4 drives the two transmission belts 6 to rotate through the two pulleys 5. The two transmission belts 6 drive the two rotating shafts 8 to rotate through the two pulleys 27. The two rotating shafts 28 drive the two eccentric wheels 9 to rotate and also drive the screening drum 10 to rotate. Because of the action of the two eccentric wheels 9, the screening drum 10 vibrates. Because the limit blocks 11 on the two rotating shafts 28 are embedded in the two supporting plates 219, the two rotating shafts 28 drive the screening drum 10 to generate longitudinal vibrations, and the longitudinal vibrations are shortened by the action of the multiple springs 17, so that the screening drum 10 will only continuously perform small-amplitude high-frequency vibrations. When the two pulleys 27 vibrate up and down with the rotating shafts 28, the forces of the two transmission belts 6 on the multiple arc blocks 25 change, causing the deformation of the springs 24 in the multiple working slots 22 to change. , and the telescopic amount of the multiple telescopic rods 23 also changes. Under the action of the multiple springs 24, the multiple arc blocks 25 are always in contact with the two transmission belts 6 to avoid the derailment of the transmission belts 6 due to vibration, which affects the use of the equipment. Because the slide bar 13 and the slide slot 12 cooperate, the hopper 14 will also vibrate, ensuring the contact between the hopper 14 and the screening drum 10, and will not cause the hopper 14 to rotate. Because the screening drum 10 is constantly shaking and rotating, it avoids excessive stacking and adhesion of starch on the screen, and plays a certain degree of self-cleaning. The purpose is to reduce the probability of blockage. At the same time, because the multiple bristles 16 on the two fixed plates 15 fit with the holes on the screening drum 10, the holes on the screening drum 10 can be cleaned when the screening drum 10 rotates. The cooperation between the limiting column 20 and the two limiting grooves 21 on the outer shell 1 can avoid misalignment when the fixed plate 15 moves up and down. The method of direct contact between the multiple bristles 16 and the screening drum 10 can timely clean the blocked holes on the screening drum 10, further preventing the blocking of the screening drum 10 and improving the work efficiency.
