Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of stepped feeder, more specifically, it relates to a stepped feeder for double-end stud. BACKGROUND

[0002] Double-end stud is a special bolt structure with a threaded head, a ring piece, and a spline head, with the center of gravity biased to the spline head side. The traditional stepped feeder faces many challenges in the screening and feeding process.

[0003] Currently, screening and feeding can be performed by a stepped feeder. However, ordinary stepped feeders rely on the weight and vibration of the stud to achieve directional arrangement and delivery. However, due to the irregularity of the geometric shape of the special-shaped double-end stud, it is easy to cause jamming, overlapping, or direction error during the feeding process, resulting in low screening efficiency and even failure to complete the feeding task. In addition, due to the special shape of the stud, additional flipping operations may be required during the feeding process to ensure the correct orientation, which further increases the complexity of feeding. Moreover, the flipping mechanism is prone to jamming during the flipping process, which requires maintenance of the flipping mechanism. However, since the flipping mechanism is usually located inside or at a critical position of the feeder, disassembly and repair require a lot of time and labor, which seriously affects production efficiency.

[0004] Therefore, a stepped feeder for double-end stud is proposed to solve the above problems. SUMMARY

[0034] Refer to Figs. 3-4 , conveying and screening assembly 5 includes linear vibration conveyor 51, linear vibration conveyor 51 top end is provided with recessed plate 52, recessed plate 52 is inclined to the vertical direction. Recessed plate 52 is opened with single-sided slot 521 near feed hopper 3 one side, recessed plate 52 is installed with sieve hopper 53 near single-sided slot 521 one side, sieve hopper 53 is arranged inside feed hopper 3. Recessed plate 52 is installed with guard plate 54 away from stepped feeding mechanism 4 one side, recessed plate 52 is installed with stud lying plate 55 away from sieve hopper 53 one side, stud lying plate 55 top is installed with screening block 56. Screening block 56 includes fixed block 561 and screening column 562, fixed block 561 is fixedly connected with stud lying plate 55, screening column 562 is arranged on fixed block 561 near sieve hopper 53 one side, screening column 562 penetrates stud lying plate 55 and is arranged.

[0035] Through the inclined recessed plate 52, the double-end stud can be hung on the end face of the lower side of the recessed plate 52 without falling, and the double-end stud is screened through the screening block 56 and the single-sided slot 521, the screening cost is reduced, the double-end stud screened through the screening block 56 can enter the side of the recessed plate 52 near the turnover assembly 6 to form a queue, thereby speeding up the production rhythm and improving the production efficiency.

[0036] Refer to Figs. 5-6 , turnover assembly 6 includes turnover housing 61, turnover housing 61 is opened with stud groove 611 near conveying and screening assembly 5 one side, stud groove 611 penetrates turnover housing 61 top end and is arranged. Turnover housing 61 is installed with rotary air cylinder 62 away from conveying and screening assembly 5 one side, the output end of rotary air cylinder 62 is arranged inside turnover housing 61, the output end of rotary air cylinder 62 is connected with turnover block 63, turnover block 63 is provided with stud turnover groove 631 near stud groove 611 one side, stud turnover groove 631 is matched with the shape of double-end stud, limit bolt 64 is arranged on one side of turnover housing 61, feed pipe 65 is arranged at the bottom end of turnover housing 61.

[0037] When the stud is stuck between the turnover block 63 and the turnover shell 61 and the rotary cylinder 62 has been started, the operator can manually release the rotary cylinder 62 and take out the stuck stud from the top end of the turnover shell 61 through the stud slot 611 provided through the top end of the turnover shell 61, thereby improving the troubleshooting efficiency.

[0038] In use, first, the operator opens the feeding port at the top end of the shell 2 to pour the studs into the feeding hopper 3. The studs move to the lower position of the feeding hopper 3, i.e. to the stepped feeding mechanism 4, through the vibrator at the bottom end of the feeding hopper 3. When the studs reach the lowest step of the stepped feeding mechanism 4, the stepped feeding mechanism 4 moves the step downward until it reaches the side of the studs through the cylinder control. The step of the stepped feeding mechanism 4 has a slope, and the lowest point of the slope is arranged away from the feeding hopper 3. At this time, the studs roll to the lowest point of the step of the stepped feeding mechanism 4. After the studs are in place, the stepped feeding mechanism 4 controls the cylinder to move the step upward so that it reaches the high position and is transported to the top end of the stepped feeding mechanism 4 through layer by layer.

[0039] Then, the studs roll to one end of the groove plate 52. The groove plate 52 is a U-shaped structure, and the blocking plate 54 blocks the rolling of the studs. The ring piece of the stud is clamped on the top end face of the groove plate 52. The studs on the groove plate 52 are moved to the side of the turnover assembly 6 through the driving of the linear vibration conveyor 51. Since the groove plate 52 is arranged obliquely, when the studs move to the position of the single-sided groove 521, the studs can be hung on the end face of the lower side of the groove plate 52 without falling. At this time, the studs have two situations. First, the threaded head of the stud faces upward, and the screening column 562 does not touch the stud. The stud smoothly passes through the single-sided groove 521 and continues to move to the turnover assembly 6. Second, the spline head of the stud faces upward, and the screening column 562 touches the stud. The stud is inclined and falls to the end face of the lower side of the groove plate 52. The studs are guided into the feeding hopper 3 through the screening hopper 53 to be re-queued.

[0040] Finally, the stud with the threaded head facing upward enters the inside of the turnover shell 61 until the stud is in contact with the stud turnover groove 631. When the downstream equipment sends a signal to the stud stepped feeder that it needs studs, the driving rotary cylinder 62 drives the turnover block 63 to rotate until the stud turnover groove 631 is on the same axis line as the feeding pipe 65. At this time, the limiting bolt 64 abuts against the turnover limiting surface 632, and the studs are pushed out of the feeding pipe 65 through the driving of the conveying gas path 66.

[0041] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.
