Description

Technical Field

[0001] This utility model relates to the field of bolt screening technology, specifically to a fast bolt screening device with automatic loading and unloading. Background Technology

[0002] Bolts, as key components for connection and fixation, directly impact the safety and stability of products. Screening can eliminate defects caused by raw material issues, improper manufacturing processes, or external environmental factors, such as cracks, porosity, and impurities. Regular bolt inspection and maintenance can promptly identify and repair potential problems, preventing production stoppages and increased maintenance costs due to bolt failures. This not only improves production efficiency but also reduces production costs, enhancing the company's economic benefits.

[0003] Chinese Patent Announcement No. CN218840836U discloses a bolt sorting and screening device. This device uses an inclined turntable, which, in conjunction with a baffle, forms a cavity to accommodate bolts. Under the action of a drive component, the turntable rotates, causing the bolts on the turntable to tumble and their shanks to randomly fall into guide grooves on the turntable. A clearance groove is provided at the center of the turntable, connecting to the guide groove. A blocking component is provided within the clearance groove to seal the connection between the guide groove and the clearance groove. Above the blocking component is a notch for accommodating one end of a slide rail. Due to the blocking component, bolts in guide grooves that do not align with the notch will not detach from the guide groove. During operation, bolts in the guide groove directly above the turntable slide down onto the slide rail that aligns with the guide groove under the influence of gravity, achieving automatic bolt sorting. This device generates relatively low noise during operation, improving the worker's experience.

[0004] However, the following defects still exist in the actual implementation process: the loading and unloading of bolts is relatively troublesome during the screening process of the device, which affects the screening efficiency of the device.

[0005] Based on this, this utility model designs an automatic bolt rapid screening device for loading and unloading to solve the above problems. Utility Model Content

[0029] The present invention will be further described below with reference to the embodiments.

A feeding track 322 is fixedly connected to the outer surface of the vibratory plate 321. A support frame 323 is fixedly connected to the lower end of the feeding track 322. The lower end of the support frame 323 is fixedly connected to the upper end of the connecting plate 31. Several bolt bodies 324 are slidably connected to the inner cavity of the feeding track 322.

[0034] The rotating assembly 33 includes a pad 331, the lower end of which is fixedly connected to the upper end of the connecting plate 31. A motor 332 is fixedly connected to the upper end of the pad 331. The output end of the motor 332 is fixedly connected to a worm gear 333 via a coupling. A worm wheel 334 is meshed with the outer surface of the worm gear 333. A drive shaft 335 is fixedly connected to the inner surface of the worm wheel 334. The lower end of the drive shaft 335 is rotatably connected to the upper end of the connecting plate 31. A reinforcing frame 336 is rotatably connected to the outer surface of the drive shaft 335. A rotating disk 337 is fixedly connected to the upper end of the reinforcing frame 336.

[0035] The screening component 34 includes a circular plate 341, an L-shaped plate 342 fixedly connected to the outer surface of the circular plate 341, the lower end of the L-shaped plate 342 fixedly connected to the upper end of the connecting plate 31, a mounting plate 343 fixedly connected to the outer surface of the circular plate 341, the lower end of the mounting plate 343 fixedly connected to the upper end of the connecting plate 31, and two positioning frames 344 fixedly connected to the front wall of the inner cavity of the mounting plate 343, with screening probes 345 fixedly connected to the inner surfaces of both positioning frames 344.

[0036] The feeding assembly 35 includes an air pump 351. The lower end of the air pump 351 is fixedly connected to the upper end of the circular plate 341. The output end of the air pump 351 is fixedly connected to a diverter pipe 352. Two connecting pipes 353 are fixedly connected to the inner surface of the diverter pipe 352. High-pressure air heads 354 are fixedly connected to the outer surfaces of the two connecting pipes 353. Positioning plates 355 are fixedly connected to the outer surfaces of the two high-pressure air heads 354. The upper ends of the two positioning plates 355 are fixedly connected to the lower end of the circular plate 341.

[0037] In this embodiment of the invention, the bolt body 324 to be screened is added to the vibratory feeder 321, allowing the bolt body 324 to be conveyed into the inner cavity of the feeding track 322 under the action of the vibratory feeder 321. With the continuous action of the vibratory feeder 321, the bolt body 324 will be squeezed forward in sequence until it slides to the leftmost end of the feeding track 322. The motor 332 is started, causing the worm gear 333 to rotate under the action of the motor 332. When the worm gear 333 rotates, it drives the worm wheel 334 meshing with it to rotate. When the worm wheel 334 rotates, it drives the transmission shaft 335 located on its inner surface to rotate. The rotation of the transmission shaft 335 drives the reinforcing frame 336 to rotate together, which eventually causes the rotating disk 337 to rotate. When the bolt body 324 is just squeezed out of the feeding track 322, it will be stuck on the inner surface of the rotating disk 337. As the rotating disk 337 rotates, the bolt body 324 will be rotated between the two screening probes 345. After passing through the two screening probes 345, the bolt body 324 continues to rotate with the rotating disk 337. When the two screening probes 345 detect that the bolt body 324 is a qualified good product, the air pump 351 will start the instant the bolt body 324 passes through the high-pressure air head 354 on the left. The air pump will transfer the gas from the diversion pipe 352 and the connecting pipe 353 to the high-pressure air head 354 on the left, blowing the bolt body 324 off the inner surface of the rotating disk 337 and into the collection box 4 on the left. When the two screening probes 345 detect that the bolt body 324 is a defective product, the air pump 351 will start the instant the bolt body 324 passes through the high-pressure air head 354 on the right. The air pump will transfer the gas from the diversion pipe 352 and the connecting pipe 353 to the high-pressure air head 354 on the right, blowing the bolt body 324 off the inner surface of the rotating disk 337 and into the collection box 4 on the right. This completes the screening of the bolt body 324.

[0038] It should be noted that the specific installation methods, circuit connection methods, and control methods of the vibratory feeder 321, motor 332, screening probe 345, air pump 351, and high-pressure air head 354 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0039] Working principle: During the bolt production process, when a device is needed to screen the bolts, the bolt bodies 324 to be screened are added to the vibratory feeder 321. Under the action of the vibratory feeder 321, the bolt bodies 324 are conveyed into the inner cavity of the feeding track 322. With the continuous action of the vibratory feeder 321, the bolt bodies 324 are pushed forward sequentially until they slide to the leftmost end of the feeding track 322, completing automatic feeding. At this time, the motor 332 is started, causing the worm gear 333 to rotate under the action of the motor 332. When the worm gear 333 rotates, it drives the meshing worm wheel 334 to rotate. When the worm wheel 334 rotates, it drives the transmission shaft 335 located on its inner surface to rotate. The rotation of the transmission shaft 335 drives the reinforcing frame 336 to rotate together, ultimately causing the rotating disk 337 to rotate. When the bolt body 324 is just squeezed out of the feeding track 322... At 22:00, the bolt body 324 will be stuck on the inner surface of the rotating disk 337. As the rotating disk 337 rotates, the bolt body 324 will be rotated between the two screening probes 345. After being detected by the two screening probes 345, it will continue to rotate with the rotating disk 337. When the two screening probes 345 detect that the bolt body 324 is a qualified good product, the air pump 351 will start the moment the bolt body 324 passes through the high-pressure air head 354 on the left. The air pump 351 will transfer the gas from the diverter pipe 352 and the connecting pipe 353 to the high-pressure air head 354 on the left, blowing the bolt body 324 off the inner surface of the rotating disk 337 and into the collection box 4 on the left. Conversely, when the bolt body 324 is a defective product, it will be blown into the collection box 4 on the right by the high-pressure air head 354 on the right, completing the automatic feeding. In this way, the screening of the bolt body 324 can be completed.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
