Description

Technical Field

[0001] This utility model relates to the field of fastener processing equipment technology, and in particular to a feeding device for a pre-coated thread coating equipment. Background Technology

[0002] The chemical adhesives used on fasteners and screws are usually called fastening adhesives or anaerobic sealants. These adhesives are primarily used to ensure that screws do not loosen during operation.

[0003] After fasteners and screws are manufactured, they need to be coated with adhesive. This coating process requires adhesive application equipment and a feeding device to transfer the parts to the adhesive application equipment for high-temperature and high-pressure coating. The feeding device usually consists of a feeding device and a feeding guide rail. The feeding device uses a lifting feeding device for auxiliary feeding. In order to prevent parts from accidentally falling into or getting stuck in the gaps of the device during the feeding and lifting process, the existing lifting feeding device has movable baffles at the inlet and outlet. However, due to the presence of the movable baffles and the angle limitation between the movable baffles and the lifting device, the number of parts that can be lifted at the same time is limited, resulting in low lifting efficiency. Therefore, a feeding device that can simultaneously take into account both safety and lifting efficiency is needed to solve this problem. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a feeding device for a pre-coated thread coating equipment, comprising an elevator and a feeding hopper. The feeding hopper is fixedly located at the bottom of the elevator. The elevator contains a lifting conveyor belt with several transfer plates. A movable baffle is located inside the feeding hopper and is rotatably connected to the hopper body. An arc-shaped plate is fixedly connected to the end of the movable baffle, and an auxiliary pushing mechanism is provided on the arc-shaped plate. The end face of the arc-shaped plate is parallel to the movable baffle. A pair of sliding grooves are symmetrically opened on both sides of the plate. The auxiliary pushing mechanism includes a pair of extension plates that match the shape of the arc plate, a connecting shaft, a torsion spring, a pair of compression springs, and an auxiliary push plate. Each of the pair of extension plates is provided with a mounting slider that matches the sliding groove. The pair of extension plates are connected to the sliding groove through the mounting slider. The two ends of the connecting shaft are respectively connected to the pair of extension plates. The auxiliary push plate is set on the connecting shaft through the torsion spring and is rotatably connected to the connecting shaft. The pair of compression springs are both set in the pair of sliding grooves and their two ends are respectively connected to the sliding groove and the mounting slider.

[0005] The above technical solution involves installing a movable baffle inside the feeding hopper, with an arc-shaped plate at one end of the movable baffle. An auxiliary pushing mechanism, including a pair of extension plates, a connecting shaft, a torsion spring, a pair of compression springs, and an auxiliary pusher plate, is installed on the arc-shaped plate. When parts are poured into the feeding hopper, they naturally concentrate on the movable baffle, with a large portion concentrating on the arc-shaped plate. As the lifting conveyor belt drives the transfer plate upwards, when the transfer plate is not in contact with the movable baffle, the end of the movable baffle, i.e., the end of the arc-shaped plate, is in contact with the end face of the lifting conveyor belt, preventing parts from falling into gaps. When the transfer plate pushes the movable baffle upwards... When the machine is in operation, a gap is created between the arc plate and the lifting conveyor belt. The parts fall into the gap and then onto the transfer plate below. As the transfer plate continues to push the movable baffle open, the parts continue to fall into the transfer plate until the transfer plate rises to a sufficient height and leaves the arc plate. At this point, the movable baffle resets under the action of gravity. During this process, when the movable baffle is pushed open, a pair of extension plates on the arc plate are ejected under the action of compression springs, which in turn ejects the auxiliary push plate. At this point, the auxiliary push plate can push the parts located in the arc plate to fall quickly into the transfer plate. When the movable baffle resets, the extension plates reset synchronously.

[0006] A further feature of this invention is that the ends of the pair of extension plates are both arc-shaped.

[0007] By adopting the above technical solution, since the ends of the pair of extension plates are both arc-shaped, the ends of the extension plates make it smoother when they come into contact with the lifting conveyor belt, further improving the flexibility of the extension plates.

[0008] A further feature of this invention is that a short baffle is fixedly provided at the end of each of the plurality of transfer plates.

[0009] By adopting the above technical solution, since each of the several transfer plates is fixedly provided with a short baffle, the parts can be prevented from falling accidentally during the lifting and transfer process.

[0010] A further feature of this invention is that a rubber shock-absorbing pad is provided at the bottom of the arc plate.

[0011] By adopting the above technical solution, since the bottom of the arc plate is provided with a rubber shock-absorbing pad, the vibration when the movable baffle collides with the next transfer plate during reset can be reduced, thus providing a certain degree of protection for the auxiliary pushing mechanism.

[0012] A further feature of this invention is that a movable baffle is also provided at the outlet of the elevator.

[0013] By adopting the above technical solution, since the outlet of the hoist is also equipped with a movable baffle, it can further prevent parts from accidentally falling into the gap of the hoisting equipment when they are transported out from the outlet. Attached Figure Description

Detailed Implementation

[0018] like Figure 1-3 As shown, a feeding device for a pre-coated thread coating equipment includes an elevator 1 and a feeding bin 2. The feeding bin is fixedly installed at the bottom of the elevator 1. The elevator is equipped with a lifting conveyor belt 3, on which several transfer plates 4 are installed. A movable baffle 5 is installed inside the feeding bin, and the movable baffle is rotatably connected to the bin body of the feeding bin 2. An arc plate 6 is fixedly connected to the end of the movable baffle, and an auxiliary pushing mechanism 7 is provided on the arc plate. The end face of the arc plate is parallel to the movable baffle 5, and a pair of sliding plates are symmetrically opened on both sides of the arc plate. The auxiliary pushing mechanism includes a pair of extension plates 9 that match the shape of the arc plate 6, a connecting shaft 10, a torsion spring, a pair of compression springs 11, and an auxiliary push plate 12. Each of the pair of extension plates is provided with a mounting slider 13 that matches the sliding groove 8. The pair of extension plates are connected to the sliding groove 8 through the mounting slider. The two ends of the connecting shaft are respectively connected to the pair of extension plates 9. The auxiliary push plate is mounted on the connecting shaft 10 through the torsion spring and is rotatably connected to the connecting shaft 10. The pair of compression springs are both located in the pair of sliding grooves 8 and their two ends are respectively connected to the sliding groove 8 and the mounting slider.

[0019] By setting a movable baffle 5 inside the feeding hopper 2, and an arc plate 6 at one end of the movable baffle 5, and an auxiliary pushing mechanism 7 including a pair of extension plates 9, a connecting shaft 10, a torsion spring, a pair of compression springs 11, and an auxiliary push plate 12 on the arc plate 6, when the parts are poured into the feeding hopper 2, they will naturally concentrate on the movable baffle 5, and a large portion of them will concentrate on the arc plate 6. As the lifting conveyor belt 3 drives the transfer plate 4 to rise, when the transfer plate 4 is not in contact with the movable baffle 5, the end of the movable baffle 5, which is also the end of the arc plate 6, is in contact with the end face of the lifting conveyor belt 3, which can prevent the parts from falling into the gap. When the transfer plate 4 pushes the movable baffle 5 upward, At this time, a gap is created between the arc plate 6 and the lifting conveyor belt 3. The part falls into the gap and then falls onto the transfer plate 4 below. As the transfer plate 4 continues to push the movable baffle 5 open, the part continues to fall into the transfer plate 4 until the transfer plate 4 rises to a sufficient height and leaves the arc plate 6. At this time, the movable baffle 5 resets under the action of gravity. During this process, when the movable baffle 5 is pushed open, a pair of extension plates 9 located on the arc plate 6 are ejected under the action of the compression spring, and the auxiliary push plate 12 is ejected together. At this time, the auxiliary push plate 12 can push the part located in the arc plate 6 to fall quickly into the transfer plate 4. When the movable baffle 5 resets, the extension plates 9 reset synchronously.

[0020] The ends of the pair of extension plates are both arc-shaped.

[0021] Since the ends of the pair of extension plates are both arc-shaped, the ends of the extension plates 9 make it smoother when they come into contact with the lifting conveyor belt 3, further improving the flexibility of the extension plates 9 in terms of extension and retraction.

[0022] Each of the several transfer plates is fixedly provided with a short baffle 14 at its end.

[0023] Since each of the aforementioned transfer plates is fixedly provided with a short baffle 14 at its end, it can prevent parts from accidentally falling during the lifting and transfer process.

[0024] A rubber shock-absorbing pad 15 is provided at the bottom of the arc plate.

[0025] Because the bottom of the arc plate is provided with a rubber shock-absorbing pad 15, it can reduce the vibration when the movable baffle 5 collides with the next transfer plate 4 when it is reset, thus providing a certain degree of protection for the auxiliary pushing mechanism 7.

[0026] The outlet of the elevator is also equipped with a movable baffle 5.

[0027] Since the outlet of the hoist is also equipped with a movable baffle 5, it can further prevent parts from accidentally falling into the gap of the hoisting equipment when they are transported out of the outlet.
