Description

Technical Field

[0001] This utility model relates to the field of equipment feeding technology, and in particular to a vibratory feeder for feeding. Background Technology

[0002] Vibratory feeders, as core feeding equipment in automated production lines, are widely used in industries such as electronics, machinery, and food. Their core function is to use directional composite vibration generated by a vibratory motor to gradually lift disordered materials in the hopper along a spiral track. Through the constraint of the track structure, the materials are neatly sorted and directionally output, ultimately providing a continuous and stable material supply for subsequent processes such as gripping, assembly, and testing. It is one of the key pieces of equipment for achieving production automation and improving efficiency.

[0003] Existing vibratory feeders require track widths that need to be adapted to different materials. When conveying materials of different sizes or shapes, the entire track must be disassembled and replaced, resulting in lengthy changeover times and reliance on professional personnel, which affects production continuity. Furthermore, the discharge port and track ends are prone to blockage due to material stacking, incorrect posture, or dimensional deviations, typically requiring manual shutdown for cleaning, increasing operational risks and labor costs, and reducing feeding efficiency. Therefore, this application proposes a vibratory feeder for material feeding. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as cumbersome track replacement for conveying different materials and inconvenient cleaning when materials become blocked, by proposing a vibratory feeder for material feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vibratory feeder for feeding includes a body, a base is fixedly connected to the bottom of the body, a plurality of feet for fixing are arranged circumferentially at the lower end of the base, a hopper is provided at the upper end of the body, and a track is provided on the inner wall of the hopper, with a plurality of extension plates embedded in the track.

[0007] The top of the hopper is provided with a groove, and a feeding plate is provided in the groove. One end of the feeding plate is provided with a flipping mechanism between it and the track, and the other end of the feeding plate extends out of the hopper.

[0008] As a further preferred embodiment of this technical solution, the track is spirally arranged, and one side wall of the track is fixedly connected to the inner wall of the hopper. A positioning groove is provided on the other side wall of the track, and multiple extension plates are arranged in the positioning groove, with the height of the multiple extension plates being equal to the height of the positioning groove.

[0009] As a further preferred embodiment of this technical solution, the extension plate extends into the positioning groove and has multiple matching grooves on one side wall, and all of the multiple matching grooves are configured as trapezoidal grooves.

[0010] All of the extension plates are configured as semicircles, and adjacent extension plates are connected to an adjustment mechanism.

[0011] As a further preferred embodiment of this technical solution, the adjustment mechanism includes a connecting block, the connecting block having an internal threaded hole, a threaded rod being disposed in the internal threaded hole, the threaded rod passing through the connecting block and being rotatably connected to the inner wall of the positioning groove, and a knob being fixedly connected to one end of the threaded rod extending outside the connecting block.

[0012] As a further preferred embodiment of this technical solution, the connecting block is disposed in the positioning groove, and the sidewalls of the connecting block are fixedly connected to two adjacent extension plates corresponding to the position.

[0013] As a further preferred embodiment of this technical solution, the tipping mechanism includes a support plate disposed on the top of the hopper, and a baffle is fixedly connected to the upper end of the support plate;

[0014] A rotary cylinder is installed below the pallet, and the rotary cylinder is detachably connected to the inner wall of the hopper by multiple sets of bolts. A support rod is keyed to the output end of the rotary cylinder, and the top of the support rod is fixedly connected to the lower surface of the pallet.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a connecting block and a threaded rod. Turning the knob drives the threaded rod to rotate synchronously. Under the limit of the internal threaded hole on the connecting block, the connecting block will move along the direction set by the threaded rod, and finally drive the end of the extension plate to adjust its position. Adjusting the length of the extension plate extending out of the positioning groove increases the width of the conveying track during the material conveying process, and prevents the material from falling off the track due to collision or shaking during the spiral ascent. It is suitable for materials of different sizes, does not require disassembly and replacement of the track, greatly reduces time and labor costs, and improves feeding efficiency.

[0017] 2. This utility model, through the setting of a rotary cylinder and support rod, allows the material to first enter the pallet and then be conveyed to the feeding plate during the material conveying process. When the material becomes blocked at the discharge port, the rotary cylinder can drive the entire pallet to flip over, sending the material gathered on the pallet back to the bottom of the hopper for reordering. At the same time, some material on the track falls downwards. The blockage at the discharge port can be handled without manual contact with the material, reducing operational risks and labor costs, and improving the feeding smoothness of the vibratory feeder and the operating efficiency of the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown, a vibratory feeder for feeding includes a body 1, a base 11 fixedly connected to the bottom of the body 1, a plurality of feet for fixing are arranged circumferentially at the lower end of the base 11, a hopper 2 is provided at the upper end of the body 1, and a track 3 is provided on the inner wall of the hopper 2. A plurality of extension plates 4 are embedded in the track 3. The track 3 is spirally arranged, and one side wall of the track 3 is fixedly connected to the inner wall of the hopper 2. A positioning groove 31 is opened on the other side wall of the track 3. The plurality of extension plates 4 are all arranged in the positioning groove 31, and the height of the plurality of extension plates 4 is equal to the height of the positioning groove 31.

[0026] Specifically, a vibrating motor and an armature are installed inside the machine body 1. When the vibrating motor is energized, it generates a periodic alternating current, causing high-frequency attraction and release actions between the armature and the motor core. This is transmitted to the hopper 2 through the rigid structure of the machine body 1, causing the hopper 2 to experience a superposition of vertical up-and-down vibration and horizontal circular vibration. Ultimately, this causes the material in the hopper 2 to spiral upwards along the track 3 and be neatly arranged under vibration regulation. It should be noted that by setting an extension plate 4 on the track 3 and dynamically adjusting its width through an adjustment mechanism, the actual conveying width of the track 3 (…) The original track width (plus the extension length of the extension plate 4) can flexibly adapt to materials of different sizes. For example, when conveying small-diameter parts, the extension plate 4 retracts to keep the track width to a minimum. When conveying large-diameter parts, the extension plate 4 extends beyond the track width to increase, preventing materials from falling off the edge of the track 3 due to insufficient width. Furthermore, through the adjustment mechanism of the extension plate 4, it is not necessary to disassemble the track 3 when changing to materials of different sizes. The operator can complete the track width adaptation by simply adjusting the extension length of the extension plate 4 with the knob 44, which greatly shortens the changeover time and improves the versatility and production efficiency of the equipment.

[0027] like Figure 3 and Figure 4 As shown, multiple matching slots 41 are provided on one side wall of the extension plate 4 extending into the positioning groove 31, and all matching slots 41 are set as trapezoidal slots. All extension plates 4 are set as semi-circular, and two adjacent extension plates 4 are connected to an adjustment mechanism. The adjustment mechanism includes a connecting block 42, and an internal threaded hole is provided on the connecting block 42. A threaded rod 43 is provided in the internal threaded hole. The threaded rod 43 passes through the connecting block 42 and is rotatably connected to the inner wall of the positioning groove 31. A knob 44 is fixedly connected to one end of the threaded rod 43 extending outside the connecting block 42. The connecting block 42 is set in the positioning groove 31, and the side wall of the connecting block 42 is fixedly connected to two adjacent extension plates 4 with corresponding positions.

[0028] It should be noted that the extension plate 4 can be made of deformable materials such as rubber. When the material shifts to the side of the track 3 and contacts the extension plate 4 under vibration, the rubber material will undergo local deformation due to the impact of the material, transforming rigid collision into flexible contact. By absorbing collision energy through deformation, it avoids scratches or deformation caused by the material colliding with the edge of the track 3 during vibration conveying. Furthermore, when the knob 44 is turned to drive the threaded rod 43 fixedly connected to it to rotate, one end of the threaded rod 43 is rotatably connected to the inner wall of the positioning groove 31 on the track 3 through a bearing. The connecting block 42 will move horizontally in a straight line along the axial direction of the threaded rod 43 due to the limitation of the internal threaded hole. Since the two sides of the connecting block 42 are respectively connected to the side walls of the two adjacent semi-circular extension plates 4, the outer edge of the rubber extension plate 4 deforms, and the gap of the matching groove 41 changes accordingly. This allows the connecting block 42 to synchronously drive the extension plate 4 to move along the positioning groove 31, realizing the rapid adjustment of the width of the track 3 and improving the adaptability of the vibratory feeder to materials of various sizes and the reliability of conveying.

[0029] like Figure 1 and Figure 5 As shown, the top of the hopper 2 has a groove, and a feeding plate 6 is provided in the groove. A flipping mechanism 5 is provided between one end of the feeding plate 6 and the track 3. The other end of the feeding plate 6 extends to the outside of the hopper 2. The flipping mechanism 5 includes a support plate 51 provided on the top of the hopper 2. A baffle 52 is fixedly connected to the upper end of the support plate 51. A rotary cylinder 54 is provided below the support plate 51. The rotary cylinder 54 is detachably connected to the inner wall of the hopper 2 by multiple sets of bolts. A support rod 53 is keyed to the output end of the rotary cylinder 54. The top of the support rod 53 is fixedly connected to the lower surface of the support plate 51.

[0030] In this process, the material in hopper 2 rises along spiral track 3 under the drive of a vibrating motor. After being sorted and arranged at the end of track 3, it enters pallet 51 in a preset posture. At this time, rotary cylinder 54 is in the initial state and pallet 51 remains horizontal. The material slides along the surface of pallet 51 under the action of vibration inertia. Baffle 52 provides lateral constraint to the material. Finally, the material is transported to the outside of hopper 2 through the docking point between pallet 51 and feeding plate 6, providing a stable material supply for subsequent processes. It should be noted that the flipping mechanism 5, as a material transition bearing platform, is horizontally set in the groove at the top of hopper 2. The baffle 52 set at the upper end of pallet 51 has the same curvature as the outer edge of hopper 2, which can prevent the material from sliding off the edge of pallet 51 during vibration, ensuring that the material enters feeding plate 6 in a directional manner. The height of pallet 51 is flush with the end of track 3 and seamlessly docks with the inlet end of feeding plate 6, avoiding material jamming or posture deviation due to height difference during transition, laying the foundation for smooth subsequent conveying.

[0031] In addition, when material gets clogged at the inlet of the feeding plate 6 or at the pallet 51, the rotary cylinder 54 can be activated. The output end of the rotary cylinder 54 drives the support rod 53 to rotate, thereby flipping the pallet 51 from a horizontal state to an angle tilted downwards. The clogged material gathered on the surface of the pallet 51 slides down the inclined surface due to gravity and falls directly back to the bottom of the hopper 2 to participate in the sorting. At the same time, the material at the end of the track 3 that has not entered the pallet 51 will fall downwards due to the gap formed by the flipping of the pallet 51, preventing the subsequent material from continuing to accumulate and aggravating the blockage. After the clogged material is cleared, the rotary cylinder 54 rotates in the opposite direction, driving the pallet 51 back to a horizontal state. The vibratory feeder restarts the feeding process, eliminating the need for manual cleaning, greatly reducing downtime caused by blockage, and ensuring the continuous and smooth feeding process.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
