Description

Technical Field

[0001] This utility model mainly relates to the field of vibratory feeder technology, specifically to a vibratory feeder for screw conveying. Background Technology

[0002] Vibratory feeders are commonly used for conveying small parts such as screws. Their working principle involves generating vibrations through components such as frequency converters and motors. Specifically, there is a pulse electromagnet under the hopper of the vibratory feeder, which can make the hopper vibrate vertically. At the same time, the inclined spring plates drive the hopper to oscillate around its vertical axis. Due to this vibration, the parts inside the hopper rise along the spiral track. During the rise, they undergo a series of track screenings or posture changes, and finally, they can automatically enter the assembly or processing position in a uniform state according to the assembly or processing requirements.

[0003] Existing vibratory feeders are fixed, so their feeding height, angle, and distance are also fixed. They can only feed materials to fixed positions and cannot be flexibly applied to different production stations. On the other hand, vibratory feeders vibrate slightly during use, which can resonate with the ground and generate noise pollution. Utility Model Content

[0031] See attached document Figure 1-6 A vibratory feeder for screw feeding, comprising:

[0032] Vibratory feeder body 1, the discharge end of the vibratory feeder body 1 is provided with multiple discharge plates 2 that can be detachably connected end to end;

[0033] The base plate 4 has a self-locking shaft 5 rotatably mounted on it. One end of the shaft 5 extends to the top of the base plate 4 and is fixedly connected to the bottom center of the vibratory feeder body 1.

[0034] The top of the connecting plate 6 is connected to the bottom of the base plate 4 through a rectangular array of buffer mechanisms 7;

[0035] The base 8 is equipped with a lifting mechanism 9, which is used to drive the connecting plate 6 to rise and fall.

[0036] In this embodiment, the feeding distance of the vibratory feeder body 1 can be changed by changing the number of detachable discharge plates 2 at both ends.

[0037] The shaft 5 can be self-locked after being driven to rotate, and the vibratory feeder body 1 can keep rotating synchronously, thus changing the feeding angle of the vibratory feeder body 1.

[0038] The buffer mechanism 7 of the rectangular array can reduce the vibration amplitude transmitted from the vibrating plate body 1 to the bottom surface, thereby reducing the noise pollution caused by resonance.

[0039] The lifting mechanism 9 can drive the connecting plate 6 to rise and fall, and the vibratory plate body 1 will rise and fall synchronously, thus changing the feeding height of the vibratory plate body 1.

[0040] The bottom of the base plate 4 is provided with a rotating frame 10, on which a worm gear 11 is rotatably mounted. One end of the worm gear 11 is equipped with a second handle 12 and is engaged with a worm wheel 13. The worm wheel 13 is fixedly mounted on the shaft 5.

[0041] In this embodiment, after the second grip 12 is held and rotated, the worm gear 11 rotates synchronously on the rotating frame 10, and drives the worm wheel 13 to rotate through meshing transmission. The shaft 5 rotates synchronously and can achieve self-locking.

[0042] The lifting mechanism 9 includes a lead screw 901, the bottom end of which is fitted with a first handle 902 and threadedly connected to a threaded groove 601 opened at the center of the surface of the connecting plate 6. The surface of the connecting plate 6 is also provided with a rectangular array of sliding grooves 602, and a movable rod 903 is slidably installed in the sliding grooves 602. The end of the movable rod 903 is fixedly installed on the top of the base 8.

[0043] In this embodiment, after the first handle 902 is gripped and rotated, the lead screw 901 rotates synchronously in the threaded groove 601, which drives the movable rod 903 to slide in the slide groove 602, thereby realizing the lifting and lowering of the connecting plate 6.

[0044] The buffer mechanism 7 includes a damping cylinder 701 and a piston rod 702 that are matched and connected. The damping cylinder 701 is fixedly installed on the bottom of the base plate 4, and the piston rod 702 is fixedly installed on the top of the connecting plate 6. A spring 703 is sleeved on the damping cylinder 701 and the piston rod 702. The two ends of the spring 703 are respectively connected to the limiting plates 704 provided on the damping cylinder 701 and the piston rod 702.

[0045] In this embodiment, when the vibratory plate body 1 vibrates, the piston rod 702 will slide slowly in the damping cylinder 701 and slowly return to its original position in conjunction with the spring 703, thereby achieving the effect of vibration reduction.

[0046] One end of the discharge plate 2 is fixedly installed with a locking block 3, and the other end is provided with a locking groove 201 that matches the locking block 3. A first threaded hole 202 is provided through the locking block 3. The first threaded hole 202 and the second threaded hole 301 that communicates with the inner wall of the locking groove 201 match each other and can be fitted together with the positioning bolt 14.

[0047] In this embodiment, after the first discharge plate 2 is fixed to the discharge end of the vibratory feeder body 1, the locking block 3 on the second discharge plate 2 is inserted into the locking groove 201 on the first discharge plate 2. At this time, the first threaded hole 202 will be aligned with the second threaded hole 301. Then, the positioning bolt 14 is installed into the aligned first threaded hole 202 and second threaded hole 301 to complete the connection between the first discharge plate 2 and the second discharge plate 2. Similarly, disassembly can be performed, or subsequent discharge plates 2 can be processed.

[0048] The base 8 is equipped with a rectangular array of self-locking casters 15 at its bottom to facilitate the movement of the device.
