Description

Technical Field

[0001] The present application relates to the technical field of screw production, and in particular to a screw screening machine. Background Art

[0002] A screw screening machine is a device used to screen and grade materials. Its working principle involves screw conveying and vibrating screening. The screws will pass through one or more vibrating screening sections. These screening sections contain a mesh with holes, in which particles smaller than the mesh holes pass through, while particles larger than the mesh holes are blocked. In this way, the material can be screened and graded.

[0003] After searching, the existing Chinese patent announcement number is: CN213855625U, a screening device during screw processing, including a screw screening body, the front end of the screw screening body is provided with a filtering mechanism and a vibration mechanism, and the vibration mechanism is located at the lower end of the filtering mechanism, and the filtering mechanism includes a chute, a vibration plate, a drop baffle, a screening plate and a screening net. The screening device during screw processing described in the utility model, by adding a filtering mechanism, can effectively screen the screws, and under the action of the chute and the vibration plate, qualified screws can be further screened out, ensuring that the probability of qualified screws appearing in defective products is reduced, and secondly, the classification plate can effectively classify the screws through the gears and the serrated blocks. The screws are on the shaking classification plate, and due to the different gravity of the production screws, they will be classified to a certain extent, further improving the efficiency of screening, and bringing better prospects for the use of screw processing screening.

[0004] In the specific implementation method of the above patent, "when it is necessary to screen the processed screws, the staff puts the screws into the screw screening body from the feed port, and the screws are transported from the conveyor to the inside of the filter mechanism. The first screening is completed under the action of the screening net. The screened screws will pass through the vibration mechanism and enter the classification plate, while the screws that have not passed will enter the screening plate. Under the action of the vibration plate, the screening plate will vibrate, so that the screws enter the chute, and the unqualified ones will roll into the vibration mechanism. The falling baffle will make the standing screws fall down, making it easier for the screws to enter the chute and then enter the vibration mechanism. The motor will drive the gear to rotate, and the gear will drive the sawtooth block to move back and forth, so that the classification plate When shaking occurs, the screws will be relatively classified due to their different weights, and the classification partitions can effectively discharge the classified screws. Finally, after the screw screening is completed, the staff stops the operation of the screw screening body and the motor, further improving the screening efficiency. In the above patent, classification plates are used to classify screws of different weights, and the classified screws are discharged through the classification partitions, which can screen the screws with high efficiency.
