Description

Technical Field

[0001] This application relates to the field of automatic feeding technology, specifically to a rotary vibratory feeder for pipe fittings. Background Technology

[0002] A vibratory feeder is an automatic orientation and sorting feeding device that uses vibration to automatically and orderly arrange disordered workpieces and accurately transport them to the next process. The vibratory feeder mainly consists of a hopper, a vibrating chassis equipped with a pulse electromagnet, a vibration controller, and a spirally expanding feeding track. To ensure the orderly orientation of components and parts with special geometric shapes, a selective passage device can be installed in the spiral feeding track to correct the positioning posture of the selected parts or to prevent incorrectly positioned parts from falling off the spiral track for reselection. This achieves the goal of automatically and orderly arranging the selected parts according to a certain set posture and transporting them to the next process stage. The pulse electromagnet causes the hopper to vibrate vertically, and because the vibrating chassis also has inclined spring plates, the hopper can torsionally vibrate around its vertical axis. The components and parts in the hopper, due to this vibration, will climb along the spiral feeding track until they are delivered to the high-level discharge port.

[0003] In existing automated packaging lines, the adjustment of the tube orientation mainly relies on vibratory feeders; however, the vibratory feeders are fixed in design, and they need to be disassembled and replaced every time the product specifications are changed, which seriously affects the flexibility of the production line; therefore, the above problems urgently need to be solved. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a tube-shaped rotary vibratory feeder.

[0005] This application provides a pipe-mounted rotary vibratory feeder, including

[0006] The hopper has a variable diameter structure, with a relatively large top diameter, an inclined bottom plate, and a circumferentially extending support edge in the middle.

[0007] The base plate is spherical, with a relatively high height in the middle and a relatively high outer edge that is on the same plane as the support edge, forming the feeding end;

[0008] A guiding mechanism, located above the support edge, includes a first baffle located at the outer ring of the support edge and a second baffle located at the inner ring of the support edge;

[0009] The first baffle extends circumferentially and is movably connected to the hopper via a connecting rod assembly, used to adjust the support width of the support edge;

[0010] The second baffle extends in a straight line and is fixedly installed on the support edge, forming a discharge end between it and the first baffle;

[0012] Furthermore,

[0013] The starting end of the first baffle is located at the feeding end and extends to the inner ring of the support edge;

[0014] The terminating end of the first baffle extends along the tangential direction of the support.

[0015] The length of the first baffle is not less than three-quarters of the perimeter of the support.

[0016] Furthermore,

[0017] The connecting rod assembly includes a fixed screw fixedly mounted on the hopper and a movable screw movably mounted on the first baffle.

[0018] The fixed screw and the movable screw are connected by a rotating sleeve, and are respectively threaded to the rotating sleeve;

[0019] The two ends of the rotating sleeve are respectively provided with reverse threads, which are used to drive the fixed screw and the movable screw to move closer or further apart.

[0020] Furthermore,

[0021] The first baffle plate is provided with a first strip-shaped hole corresponding to the movable screw;

[0022] The extension direction of the first strip hole is the same as the extension direction of the first baffle.

[0023] The movable screw is T-shaped, including a large diameter located on the side of the first baffle away from the rotating sleeve and a small diameter passing through the first strip hole.

[0024] Furthermore,

[0025] The smaller diameter has a square-shaped joint at one end near the larger diameter;

[0026] The distance between the two sides of the docking part is matched with the width of the first strip hole, which is used to restrict the rotation of the movable screw;

[0027] The distance between the two ends of the docking portion is relatively smaller than the thickness of the first baffle.

[0028] Furthermore,

[0029] A matching locking nut is also fitted onto the small diameter;

[0030] The locking nut is threaded to the minor diameter and is used to lock the movable screw onto the first baffle.

[0031] Furthermore,

[0032] One end of the second baffle is fixedly installed on the support edge, and the other end extends to the outside of the hopper;

[0033] The end of the first baffle is parallel to the second baffle and extends to the outside of the hopper, forming a discharge port between the first baffle and the second baffle;

[0034] The hopper is provided with a corresponding clearance opening for the discharge port.

[0035] Furthermore,

[0036] The first baffle and the second baffle are connected by a lead screw;

[0037] The lead screw is located outside the hopper, with its two ends passing through the first baffle and the second baffle, respectively.

[0038] The lead screw is provided with lock nuts on both sides of the first baffle and the second baffle, which are used to adjust the distance between the first baffle and the second baffle.

[0039] The advantages and positive effects of this application are:

[0040] This technical solution uses an inclined, spherical arc-shaped bottom plate at the bottom of the hopper to allow materials inside the hopper to spread rapidly in all directions and enter the screening plane formed by the support edge and guide mechanism through the junction of the bottom plate and the support edge. Materials that meet the specified placement pattern can pass through, while those that do not fall directly back into the hopper. When changing product specifications, the support width of the support edge can be adjusted by adjusting the distance between the first baffle and the side wall of the hopper through the linkage assembly, thereby meeting the screening requirements of different product specifications.

The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0046] Please refer to Figure 1-3 This embodiment provides a pipe fitting rotary vibratory feeder, including a hopper 100, which has a variable diameter structure with a relatively large top diameter and an inclined bottom plate 110. A circumferentially extending support edge 120 is formed in the middle. The bottom plate 110 is spherical with a relatively high middle height, and the relatively high end of the outer edge is located on the same plane as the support edge 120, forming a feeding end. A guiding mechanism is located above the support edge 120 and includes a first baffle 13 located at the outer circumference of the support edge 120. 0 and a second baffle 140 located on the inner ring of the support edge 120; the first baffle 130 extends circumferentially and is movably connected to the hopper 100 via a connecting rod assembly, for adjusting the support width of the support edge 120; the second baffle 140 extends linearly and is fixedly installed on the support edge 120, forming a discharge end between it and the first baffle 130; a base 200 is installed below the hopper 100 and has a vibration mechanism inside for driving the hopper 100 to vibrate.

[0047] In this embodiment, the top of the hopper 100 is an open structure, allowing direct feeding. The inner cavity has a variable diameter structure, with a ring-shaped support edge 120 in the middle. The bottom is provided with an inclined, spherical arc-shaped base plate 110. When material is fed into the hopper 100, the spherical arc-shaped structure of the base plate 110 allows the material to spread outwards at an accelerated rate. Combined with the inclined mounting structure of the base plate 110, the material can continuously enter the support edge 120 under continuous vibration and move forward along the support edge 120 in a specified direction.

[0048] In this embodiment, the first baffle 130 is movably mounted on the side wall of the hopper 100 via a connecting rod assembly and is located above the support edge 120. The distance between the first baffle 130 and the side wall assembly of the hopper 100 can be effectively adjusted by driving the connecting rod assembly, thereby adjusting the support width of the other side support edge 120 to meet the needs of materials of different specifications.

[0049] In a preferred embodiment, the starting end of the first baffle 130 is located at the feeding end and extends to the inner circle of the support edge 120; the ending end of the first baffle 130 extends along the tangent direction of the support edge 120; and the length of the first baffle 130 is not less than three-quarters of the circumference of the support edge 120.

[0050] In this embodiment, the starting end of the first baffle 130 extends to the inner ring of the support edge 120, forming an arc-shaped limit at the junction of the bottom plate 110 and the support edge 120, which is used to restrict the material to move only in a specified direction after entering the support edge 120.

[0051] In this embodiment, the terminating end of the first baffle 130 extends along the tangent direction of the support line 120, and together with the second baffle 140, they can form an output channel, allowing materials to be discharged sequentially.

[0052] In a preferred embodiment, the connecting rod assembly includes a fixed screw 300 fixedly mounted on the hopper 100 and a movable screw 310 movably mounted on the first baffle 130; the fixed screw 300 and the movable screw 310 are connected by a rotating sleeve 320 and are respectively threaded to the rotating sleeve 320; both ends of the rotating sleeve 320 are respectively provided with reverse threads for driving the fixed screw 300 and the movable screw 310 to move closer or further apart.

[0053] In this embodiment, the fixing screw 300 is fixedly installed on the inner wall of the hopper 100, and the sliding screw 310 is installed through the first baffle 130 and can slide on the first mounting plate 130 along its extension direction. Thus, during the adjustment process, the length compensation of the first mounting plate 130 can be achieved by sliding.

[0054] In this embodiment, the movable screw 310 and the fixed screw 300 are connected by a rotating sleeve 320 and are threadedly connected to the rotating sleeve 320 respectively; at the same time, the two ends inside the rotating sleeve 320 are respectively provided with reverse threads, which can synchronously drive the movable screw 310 and the fixed screw 300 to move closer or further away from each other.

[0055] In a preferred embodiment, the first baffle 130 is provided with a first strip hole 131 corresponding to the movable screw 310; the extension direction of the first strip hole 131 is the same as the extension direction of the first baffle 130; the movable screw 310 is T-shaped and includes a large diameter located on the side of the first baffle 130 away from the rotating sleeve 320 and a small diameter passing through the first strip hole 131.

[0056] In this embodiment, the first baffle 130 is provided with a first strip hole 131 corresponding to the movable screw 310, so that the movable screw 310 can slide relative to the first baffle 130; at the same time, the movable screw 310 is T-shaped in general, which can pass through the first baffle 130 without detaching from the first baffle 130.

[0057] In a preferred embodiment, the end of the smaller diameter near the larger diameter is provided with a square-shaped mating portion; the distance between the two sides of the mating portion matches the width of the first strip hole 131, which is used to restrict the rotation of the movable screw 310; the distance between the two end faces of the mating portion is relatively smaller than the thickness of the first baffle 130.

[0058] In a preferred embodiment, a matching locking nut 311 is also fitted on the minor diameter; the locking nut 311 is threadedly connected to the minor diameter and is used to lock the movable screw 310 onto the first baffle 130.

[0059] In this embodiment, a square-shaped docking part is provided at the end of the smaller diameter near the larger diameter, and the thickness of the docking part is relatively smaller than that of the first baffle 130. This allows it to both engage with the first strip hole 131 to restrict rotation and not affect the stroke of the locking nut 311, so that the movable screw 310 can be locked and installed on the first baffle 130.

[0060] In a preferred embodiment, one end of the second baffle 140 is fixedly mounted on the support edge 120, and the other end extends to the outside of the hopper 100; the end of the first baffle 130 is parallel to the second baffle 140 and extends to the outside of the hopper 100, forming a discharge port between the first baffle 130 and the second baffle 140; the hopper 100 is provided with a corresponding clearance opening corresponding to the discharge port.

[0061] In this embodiment, the ends of the first baffle 130 and the second baffle 140 extend to the outside of the hopper 100, forming a discharge port of the hopper 100 to the outside; the hopper 100 is provided with a corresponding clearance opening for the discharge port.

[0062] In this embodiment, the external conveying mechanism extends to the opening below the discharge port, so that after the material is discharged through the hopper 100, it can still be discharged in the specified direction according to the specified placement method.

[0063] In a preferred embodiment, the first baffle 130 and the second baffle 140 are connected by a lead screw 400; the lead screw 400 is located outside the hopper 100, and its two ends pass through the first baffle 130 and the second baffle 140 respectively; lock nuts 410 are also provided on both sides of the lead screw 400 on the first baffle 130 and the second baffle 140 respectively, for adjusting the distance between the first baffle 130 and the second baffle 140.

[0064] In this embodiment, the portions of the first baffle 130 and the second baffle 140 extending outside the hopper 100 are connected by a lead screw 400, thereby ensuring the stability of the discharge port. The lead screw 400 passes through both the first baffle 130 and the second baffle 140. The lock nuts 410, which are fitted on the lead screw 400 and located on both sides of the first baffle 130 and the second baffle 140 respectively, can not only achieve the locking installation between the lead screw 400 and the first baffle 130 and the second baffle 140, but also allow for arbitrary adjustment of the distance between the first baffle 130 and the second baffle 140.
