Description

Technical Field

[0001] The utility model relates to the technical field of screw feeders, in particular to a stepped feeder. Background Art

[0002] The stepped feeder is a device that can transport and feed screws one by one. When the screws are transported, a nail blowing component is installed at the discharge position. When the screws are moved to the conveying pipe, the screws are blown into the conveying pipe to achieve accurate feeding of the screws.

[0003] When conveying screws, the existing step feeder generally conveys a single screw to the conveying pipe through an intermittent component, and then conveys the single screw to the installation position through the conveying pipe. For some workpieces that need to install multiple screws, multiple groups of step feeders are required to feed materials to achieve the installation of screws at multiple positions of the workpiece, resulting in a larger overall processing device and a more complicated working process. At the same time, when the existing step feeder is in use, the screws are pushed by a movable push plate. The size of the push plate limits the number of screws that can be pushed, and limits the number of screws conveyed. Utility Model Content

[0023] like Figures 1 to 5 As shown, a receiving groove 9 for slidingly receiving the extension plate 4 is provided at the top of the push plate 3, and a positioning hole 10 is symmetrically provided on one side of the receiving groove 9. A positioning rod 11 is fixedly installed at the top of the push plate 3 corresponding to the position of the positioning hole 10, and the positioning rod 11 is slidably connected to the positioning hole 10. A return spring 12 is sleeved on the outer side of the positioning rod 11, and one end of the return spring 12 is fixedly connected to one side of the extension plate 4, and the other end of the return spring 12 is fixedly connected to the push plate 3. An extrusion slope 13 is provided at the bottom of the extension plate 4.

[0024] The operation of the stepped feeder body 2 drives the push plate 3 to push the screws inside the stepped feeder body 2. When the extension plate 4 on the push plate 3 exceeds the stepped plate at the fixed position in the stepped feeder body 2, the extension plate 4 is driven to slide out of the storage groove 9 by the push of the return spring 12. At this time, the extension plate 4 can transport more screws to a higher level until they are transported to the conveyor belt of the stepped feeder body 2.

[0025] like Figures 1 to 5 As shown, a servo motor 14 is fixedly mounted on the bottom of the first fixed plate 5 , and an output end of the servo motor 14 passes through the first fixed plate 5 and is fixedly connected to the turntable 6 , and the servo motor 14 controls the turntable 6 to rotate intermittently.

[0026] like Figures 1 to 5 As shown, a second fixed plate 15 is fixedly installed inside the work station 1, a sliding plate 16 is slidably installed at one end of the second fixed plate 15, a fixed rod 17 is fixedly installed at one end of the sliding plate 16, a mounting ring 18 is fixedly installed at the bottom of the fixed rod 17, and the push rod 8 is fixedly installed on one side of the mounting ring 18.

[0027] By controlling the movement of the sliding plate 16, the push rod 8 on the mounting ring 18 can be driven to push the three screws, so that the screws slide out of the receiving hole 7 and fall into the guide tube 27, thereby realizing the simultaneous conveyance of the three screws.

[0028] like Figures 1 to 5 As shown, the top of the turntable 6 is provided with a V-groove 19 in a ring array with the central axis of the turntable 6 as the axis, there are six V-grooves 19, and several V-grooves 19 are arranged in a continuous manner.

[0029] As the turntable 6 rotates, the screws will be driven to the guide tube 27. When the fixed rod 17 moves to the top of the V-groove 19, the push rod 8 will not push the three screws. As the servo motor 14 drives the turntable 6 to rotate intermittently, the sliding plate 16 is pulled by the pulling spring 20. When the fixed rod 17 moves to the bottom groove of the V-groove 19, the push rod 8 on the mounting ring 18 installed on the fixed rod 17 will push the three screws.

[0033] The utility model provides a stepped feeder, and the specific working principle is as follows:

[0034] When the device is in use, the operation of the stepped feeder body 2 drives the push plate 3 to push the screws inside the stepped feeder body 2. When the extension plate 4 on the push plate 3 exceeds the stepped plate at a fixed position in the stepped feeder body 2, the push of the return spring 12 will drive the extension plate 4 to slide out of the storage groove 9. At this time, the extension plate 4 can transport more screws to a higher level until they are transported to the conveyor belt of the stepped feeder body 2. When the push plate 3 falls, the extrusion slope 13 under the extension plate 4 will squeeze the stepped plate at a fixed position in the stepped feeder body 2, so that the extension plate 4 can be stored in the push plate 3. The servo motor 14 The turntable 6 is driven to rotate intermittently, so that the screws can be intermittently stored inside the storage hole 7. As the turntable 6 rotates, the screws are driven to be transported to the guide tube 27. When the fixed rod 17 moves to the top of the V-shaped groove 19, the push rod 8 will not push the three screws. As the servo motor 14 drives the turntable 6 to rotate intermittently, the sliding plate 16 is pulled by the pulling spring 20. When the fixed rod 17 moves to the bottom groove of the V-shaped groove 19, the push rod 8 on the mounting ring 18 installed on the fixed rod 17 will push the three screws, causing the screws to slide out of the storage hole 7 and fall into the guide tube 27, thereby realizing the simultaneous transportation of the three screws.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
