Description

Technical Field

[0001] This utility model relates to the technical field of bolt cutting tools, and in particular to a bolt cutting mechanism. Background Technology

[0002] In the semi-finished bolt processing, bolts need to be arranged in advance to ensure their rapid use in subsequent processing. However, due to the large volume of bolts, it is inconvenient for workers to arrange them one by one. In the operation of an existing automatic bolt feeding machine, bolts often stack up, causing blockage of the conveying channel of the conveying device. Secondly, because the arranged bolts are close together, when the first bolt is removed in the next processing step, the next bolt quickly follows, causing material removal blockage. Since the arranged bolts are in the discharge trough, the bolts inside the discharge trough usually need to be pushed forward by the bolts on the rear conveying device to move forward, which can easily cause bolts to block the discharge trough. Therefore, the above technical problems need to be solved. Utility Model Content

The upper layer is a feeding chamber, with three sets of inclined abutments of different heights arranged horizontally in the middle of the feeding chamber, and three sets of sliding grooves arranged vertically at the rear ends on both sides. The lower layer of the feeding hopper 1 is an installation chamber, with a push plate 2 horizontally installed in the middle of the inner side of the installation chamber. The upper end of the push plate 2 has three branch plates of different heights, and the lower end has a semi-circular boss arranged vertically in the middle. The top surface of the branch plates is inclined, and a motor 3 is arranged vertically at the lower end of the push plate 2. The motor 3 is fixedly connected to the floor of the installation chamber, and a cam 8 is installed at the front end of the drive shaft of the motor 3, which abuts against the semi-circular boss. A transmission device 4 is horizontally installed at the upper rear end of the feeding hopper 1. The conveyor belt of the transmission device 4 is flush with the top surface of the feeding hopper 1, and a transmission device 4 is installed at the rear end on one side. The device is equipped with a second motor 7, whose drive shaft is connected to the internal rollers of the transmission device 4 via a coupling. A limit plate 5 is longitudinally installed in the middle of the baffle on the other side of the transmission device 4. A collection trough 6 is longitudinally inclined on the other side of the feed hopper 1. The inlet end of the collection trough 6 is located at the lower end of the limit plate 5 and is flush with the top surface of the baffle on the other side of the transmission device 4. The outlet end of the collection trough 6 is connected to the outer wall of one side of the feed hopper 1 and passes through the outlet. The push plate 2 can move up and down by the mutual rotation of the first motor 3 and the cam 8. The push plate 2 and the abutment plate can push the bolts in the feed hopper upwards step by step onto the conveyor belt. The second motor 7 can provide power to the transmission device 4. The limit plate 5 can push out the bolts stacked on the conveyor belt. The collection trough 6 can make the pushed bolts flow back into the feed hopper.

[0021] In this utility model, a discharge trough 10 is horizontally installed on the other side of the transmission device 4. The discharge trough 10 is movably hinged to the other side of the transmission device 4. A vibrating motor 9 is horizontally installed in the middle of the front end face of the discharge trough 10, and a telescopic rod 13 is movably hinged to one side of the bottom surface of the discharge trough 10. A support plate is fixed to the bottom end of the telescopic rod 13. Support platforms are provided at both ends of one side of the discharge trough 10. A through mounting hole is vertically opened at the bottom of the two support platforms. A rotating shaft is vertically installed in the middle of the mounting hole and passes through the bottom surface of the discharge trough 10. A rotating blade 12 is horizontally installed in the middle of the rotating shaft. Two gears 14 are horizontally installed at the other end of the two rotating shafts. The two gears 14 mesh with each other. A motor 11 is vertically mounted on the lower end of wheel 14. The drive shaft of motor 11 is connected to gear 14. A protective cover is provided horizontally on one side of the discharge chute 10. Motor 11 is fixed to the inner wall of the protective cover. The discharge chute 10 facilitates the sorting of bolts that have fallen on the conveyor belt. The vibrating motor 9 facilitates the movement of bolts on the support platform. The telescopic rod 13 facilitates the control of the tilt angle of the discharge chute 10. The rotating blade 12 facilitates the adjustment of the gap between bolts. The cooperation between motor 11 and gear 14 facilitates the meshing and rotation of the two rotating blades 12. The protective cover facilitates the covering of the rotating blades 12 and motor 11.

[0022] Working Principle: In use, the semi-finished bolts are first poured into the feeding hopper. Motor 3 rotates, causing cam 8 to rotate and push pusher 2 upwards and downwards. This moves the branch plate at the upper end of pusher 2, pushing the bolts in the feeding hopper upwards step by step until they fall onto the conveyor belt. Motor 7 drives the transmission device 4 to transport the bolts forward on the conveyor belt. When the bolts reach the lower end of limit plate 5, limit plate 5 pushes out the stacked bolts, causing them to fall into collection trough 6. The collected bolts then re-enter the collection trough. The bolts are reloaded into the feeding hopper. The other bolts that have passed through the limit plate 5 enter the discharge trough 10 for arrangement, with the bolt shanks pointing downwards and the bolt heads pointing upwards. By vibrating the vibrating motor 9 and adjusting the extension length of the telescopic rod 13, the tilt angle of the discharge trough 10 is increased, causing the bolts in the middle of the discharge trough 10 to move forward. When they reach the rotating blade 12, the motor 11 rotates, causing the two gears 14 to mesh and rotate, which in turn drives the rotating shaft and the rotating blade 12 to rotate, thus isolating the bolts about to be discharged from the bolts at the rear end, facilitating subsequent processing of the bolts.
