Technical Field

[0001] The invention relates to the technical field of feeding devices, in particular to a push-pull type feeding device. Background Art

[0002] Feeding systems are commonly found in automated product assembly lines. Their main function is to arrange small parts (such as screws and nuts) that are randomly piled together in an orderly manner according to a certain rule, and to transport the parts one by one to the designated location. The common feeding device in the prior art is the vibration plate feeding, but the vibration plate feeding is not very effective for long rod materials. For this reason, a push-pull feeding device has appeared on the market. This device is suitable for feeding rod parts; however, this device has the following disadvantages: during the push-pull process, the material rubs against the push plate, which can easily damage the surface coating of the rod parts, especially the screw parts.

[0018] The bottom of the first slide plate 21 and the third slide plate 23 are fixedly connected by a connecting plate 24; a driving device for driving the connecting plate 24 to slide is provided on the third fixed plate 13; the driving device is a cylinder 10, and the push rod of the cylinder 10 is fixedly connected to the bottom center of the connecting plate 24; the second slide plate 22 is provided with a first rack 6 on both sides; the third slide plate 23 is provided with a second rack 4 on both sides; the vertical plate 2 is provided with a first slide groove 7 and a second slide groove 3 respectively cooperating with the first rack 6 and the second rack 4; the first rack 6 and the second rack 4 extend out of the surface of the vertical plate 2 from the first slide groove 7 and the second slide groove 3 respectively, and can slide along the length direction of the slide groove. A gear 5 meshing with the first rack 6 and the second rack 4 is also rotatably provided on the outer side of the vertical plate 2; the top of the first slide plate 21, the second slide plate 22, and the third slide plate 23 are all provided with a top plate 8, and a baffle plate 81 is hingedly provided on the side of the top plate 8 close to the third fixed plate 13;

[0019] When the first slide 21 and the third slide 23 are raised to the highest point, the lower end of the baffle plate 81 on the first slide 21 and the third slide 23 is higher than the first fixed plate 11 and the third fixed plate 13, and the baffle plate 81 loses support and expands at least 90 degrees in the discharge direction; it overlaps the upper end of the first fixed plate 11 and the third fixed plate 13. It should be understood that at this time, the baffle plate 81 cooperates with the upper end of the next ejector plate 8 to move the material to the next ejector plate. At the same time, the second slide 22 drops to the lowest point, and the ejector plate 8 on the second slide 22 is lower than the height of the first fixed plate 11 to withstand the moving material.

[0020] When the second slide plate 22 rises to the highest point, the lower end of the material baffle plate on the second slide plate 22 is higher than the second fixed plate 12, and the material baffle plate 81 of the second slide plate 22 loses support and expands at least 90 degrees in the discharge direction; it is overlapped to the upper end of the second fixed plate 12; at the same time, the first slide plate 21 and the third slide plate 23 drop to the lowest point, and the top plate 8 on the first slide plate 21 and the third slide plate 23 are respectively lower than the bottom of the material box 9 and the height of the second fixed plate 12.

[0021] In another embodiment, the top of the ejector plate 8 is an inclined surface or a curved surface inclined toward the third fixed plate (discharging direction).

[0022] In another embodiment, grooves 82 are provided at both ends of the ejector plate 8 , and a hinge shaft 83 is provided in the groove 82 ; shaft sleeves 84 are extended from the bottom of both ends of the baffle plate 81 , and the shaft sleeves 84 are adapted to the hinge shaft 83 .

[0023] In another embodiment, the shaft sleeve 84 is tangent to the baffle plate 81; a stopper groove 85 for accommodating the baffle plate 81 is provided on the side of the ejector plate 8 close to the baffle plate 81. This arrangement can make the side of the baffle plate 81 close to the discharge direction flush with the side of the ejector plate 8 close to the discharge direction, making it convenient for the baffle plate 81 to be retracted toward the ejector plate 8.

[0024] The working process is as follows:

[0025] Pour the rod-shaped material into the material box 9;

[0026] The cylinder lifts up the first slide plate 21 and the third slide plate 23 to the highest point. At the same time, the second slide plate 22 is lowered to the lowest point under the action of the gear 5. The first slide plate 21 lifts the material to the highest point. Under the action of the gravity of the material, the baffle plate 81 of the first slide plate 21 is forced to unfold from the top plate 8 to the first fixed plate 11, and the material rolls down from the top plate 8 and the baffle plate 81; to the upper end of the top plate 8 of the second slide plate 22, and abuts against the baffle plate 81.

[0027] The cylinder descends, pulling the first slide plate 21 and the third slide plate 23 to the lowest point. At the same time, the second slide plate 22 rises to the highest point under the action of the gear 5. The second slide plate 22 lifts the material to the highest point. Under the action of the gravity of the material, the baffle plate 81 of the second slide plate 22 is forced to unfold from the top plate 8, and the material rolls down from the top plate 8 and the baffle plate 81 to the upper end of the top plate 8 of the third slide plate 23, and abuts against the baffle plate 81.

[0028] The cylinder lifts the first slide 21 and the third slide 23 to the highest point. At the same time, the second slide 22 is lowered to the lowest point under the action of the gear 5. The first slide 21 lifts the material to the highest point. Under the action of the gravity of the material, the baffle plate 81 of the first slide 21 is forced to unfold from the top plate 8 to the first fixed plate 11, and the material rolls down from the top plate 8 and the baffle plate 81; to the upper end of the top plate 8 of the second slide 22, and abuts against the baffle plate 81; at the same time, the third slide 23 lifts the material to the highest point. Under the action of the gravity of the material, the baffle plate 81 of the third slide 23 is forced to unfold from the top plate 8 to the third fixed plate 13, and the material rolls down from the top plate 8 and the baffle plate 81 to the discharge port.

[0029] The above steps are repeated to gradually convey the material in the material box 9 to the discharge port; during the process, due to the effect of the baffle plate 81, the material can avoid friction with the fixed plate.

[0030] The above descriptions are only preferred embodiments of the present invention, not all embodiments. Anyone should be aware that any structural changes made under the inspiration of the present invention, and any technical solutions that are the same or similar to the present invention, belong to the protection scope of the present invention.
