Aviation-sealing-based hollow sealing ball defective gas screening device

Abstract

The invention provides an aviation-sealing-based hollow sealing ball defective gas screening device, relates to the technical field of defective screening devices, and solves the problems that a defective product is prone to being clamped in screen holes during screening, so that a next ball cannot be screened through the screen holes, and feeding, screening, separation of the defective product from the screen holes and pneumatic discharging of the defective product cannot be achieved through structural improvement and driving of one electric element. The aviation-sealing-based hollow sealingball defective gas screening device comprises a screening barrel and a plate body, wherein a feeding pipe is connected to the screening barrel, and a screening structure is connected to the screeningbarrel in a sliding mode. Due to the fact that the left end face of the plate body is subjected to oblique angle treatment, switching between a sealing state and an opening state of the three screen holes can be achieved through left-right movement of the plate body, the defective product can be ejected out of the screen holes through the plate body with the left end face subjected to the obliqueangle treatment, and then follow-up clearing of the defective product is facilitated.

Description

technical field [0001] The invention belongs to the technical field of screening devices for defective products, and more specifically relates to a gas screening device for defective products based on hollow sealing balls for aviation sealing. Background technique [0002] Hollow sealed spheres are one of the tiny aerospace parts, and the sealed spheres need to be strictly screened after production to prevent safety accidents caused by assembling defective products. [0003] For example, the application number: CN201910813556.5, the invention discloses a screening device for defective products of traditional Chinese medicine capsules, including a feeding conveyor belt, a push rod, a screening slideway and a collection tank, and the screening slideway is set on the raised part in the middle of the frame , the inner end of the push rod is movably inserted into the left end of the screening chute, the outer end is hinged to one end of the connecting rod, the other end of the co...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a gas screening device for defective products based on hollow sealing balls for aviation sealing, to solve the existing problem that the defective products are easily stuck in the sieve holes during screening of the existing device, resulting in the next The spheres cannot be screened through the sieve holes, which affects the screening efficiency; moreover, most of the existing devices are screened through multiple electrical components, resulting in an increase in the cost of the screening equipment, and it is impossible to use a single screen through structural improvements. Electric components drive to realize the problem of feeding, screening, defective products leaving the screen hole and pneumatic unloading of defective products
