Description

Technical Field

[0001] The utility model relates to the technical field of stacking devices, and more specifically, to a stacking device for metal nut blanking. Background Technique

[0002] During the nut processing, in order to facilitate the management of a large number of nuts by personnel, it is necessary to align and stack the nuts after blanking. For example, a finished product collection and stacking device with the patent publication number CN211056211U includes: a conveyor belt; a baffle, which is arranged downstream of the conveyor belt; a chute, which is connected to the baffle and located between the baffle and the conveyor belt; a collection box, which is arranged between the baffle and the conveyor belt and below the chute to receive the finished products falling from the chute. According to the finished product collection and stacking device of this utility model, the finished products can be better collected and stacked.

[0003] Although the existing stacking devices can perform stacking operations on materials, when facing nut-like materials, due to the small size of the nuts, it is impossible to ensure that the nuts can be accurately placed flat when falling, and thus some nuts will be vertically stuck in the materials during continuous blanking, affecting the stacking work. Therefore, we make improvements and propose a stacking device for metal nut blanking to ensure that the nuts can be uniformly placed flat together for easy handling and transfer by personnel. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a stacking device for metal nut blanking, which can effectively solve the problem that some nuts will fall vertically during nut stacking, thereby reducing the stacking effect.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A stacking device for metal nut blanking includes a platform, a bracket is fixedly installed on the lower side of the platform, an auxiliary component for guiding nut stacking is arranged in the center of the platform, a positioning column for aligning nuts is fixedly installed in the middle of the auxiliary component, an adjusting component for adapting to the size of the nuts is arranged on the surface of the platform, and a stacking limit column for limiting the nuts is arranged above the adjusting component.

[0007] Preferably, arc-shaped clamping plates and flat clamping plates are respectively fixedly installed on both sides of the column body of the stacking limit column, and a guide plate for guiding the falling position of the nuts is rotatably installed at the upper end of the stacking limit column.

[0008] Preferably, a guiding rod for facilitating the insertion of the nuts is arranged at the upper end of the positioning column, and a connecting rod for connection is arranged at the lower end of the positioning column.

[0009] Preferably, the auxiliary component includes a through hole which is opened at the center of the platform. A limiting ring is fixedly installed inside the through hole, and the inside of the limiting ring is connected to a connecting rod.

[0010] Preferably, a bottom plate is fixedly installed at the bottom of the connecting rod. A first motor is fixedly installed on one side of the lower surface of the platform. An eccentric wheel is fixedly installed at the output end of the first motor. A transmission connecting rod is movably connected between one side of the eccentric wheel and one side of the bottom plate, and the transmission connecting rod and the bottom plate are connected by a ball hinge.

[0011] Preferably, the adjusting component includes a plurality of adjusting grooves. Adjusting rods are slidably installed inside the adjusting grooves, and a stacking limiting post is installed on the upper surface of each adjusting rod.

[0012] Preferably, a rotating groove is opened in the middle of the lower surface of the platform. A rotating sleeve is rotatably installed inside the rotating groove. A driving plate is fixedly installed on the lower surface of the rotating sleeve. A plurality of limiting grooves are opened on the surface of the driving plate, and the limiting grooves are in limiting cooperation with the adjusting rods.

[0013] Preferably, a second motor is fixedly installed on one side of the lower surface of the platform. A gear is fixedly installed at the output end of the second motor. Teeth are fixedly installed on the outside of the driving plate, and the teeth are meshed with the gear.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) By starting the first motor to drive the eccentric wheel to rotate, the bottom plate is driven to swing under the connection of the transmission connecting rod, and then the connecting rod swings inside the limiting ring, so that the whole positioning column is adjusted by a certain amplitude, avoiding that some nuts are stuck on the positioning column when falling, resulting in the nuts being unable to fall normally, thereby improving the efficiency of nut stacking and avoiding the situation that subsequent normal stacking cannot be carried out due to material jamming.

[0016] (2) By starting the second motor to drive the gear to rotate, using the rotational cooperation between the rotating sleeve and the rotating groove, the teeth are meshed with the gear, and then the driving plate rotates. During the rotation of the driving plate, the position of the limiting groove changes, and through the shape setting of the limiting groove, the adjusting rod moves along the position of the limiting groove and is limited by the rotating groove to adjust the positions of multiple stacking limiting posts, so that the application can be adjusted to the limit of the required nut size as needed, further strengthening the accuracy of nut stacking and avoiding poor stacking effect caused by chaotic nut sorting.

Specific embodiments

[0024] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 to 6 shown, a metal nut blanking and stacking device includes a platform 1, a bracket 2 is fixedly installed on the lower side of the platform 1, an auxiliary component 5 for guiding nut stacking is arranged at the center of the platform 1, a positioning post 4 for aligning nuts is fixedly installed in the middle of the auxiliary component 5, an adjustment component 3 for adapting to the size of the nuts is arranged on the surface of the platform 1, and a stacking limit post 6 for limiting the nuts is arranged above the adjustment component 3.

[0026] In this embodiment, arc-shaped clamping plates 7 and flat clamping plates 8 are respectively fixedly installed on both sides of the column body of the stacking limit post 6, and a material guiding plate 9 for guiding the falling position of the nuts is rotatably installed at the upper end of the stacking limit post 6.

[0027] During the stacking process, in order to adapt to different types of nuts due to their different outer shapes, the position between the arc-shaped clamping plate 7 and the flat clamping plate 8 can be adjusted by rotating the stacking limit post 6, realizing the switching and fixing of the straight surface and the arc surface, and improving the application range of this application.

[0028] In this embodiment, a guiding rod 401 convenient for the nut to be sleeved is arranged at the upper end of the positioning post 4, and a connecting rod 402 for connection is arranged at the lower end of the positioning post 4.

[0029] In this embodiment, the auxiliary component 5 includes a through hole 501. The through hole 501 is opened at the center of the platform 1. A limiting ring 502 is fixedly installed inside the through hole 501, and the inside of the limiting ring 502 is connected to the connecting rod 402.

[0030] In this embodiment, a bottom plate 503 is fixedly installed at the bottom of the connecting rod 402. A first motor 506 is fixedly installed on one side of the lower surface of the platform 1. An eccentric wheel 504 is fixedly installed at the output end of the first motor 506. A transmission connecting rod 505 is movably connected between one side of the eccentric wheel 504 and one side of the bottom plate 503, and the transmission connecting rod 505 is connected to the bottom plate 503 through a spherical hinge.

[0031] By starting the first motor 506 to drive the eccentric wheel 504 to rotate, the bottom plate 503 is driven to swing under the connection of the transmission connecting rod 505. Further, the connecting rod 402 swings inside the limiting ring 502, so that the overall positioning post 4 is adjusted by a certain amplitude, avoiding that some nuts are stuck on the positioning post 4 due to the material when falling, resulting in the nuts being unable to fall normally, and further improving the efficiency during the nut stacking process and avoiding the situation that subsequent normal stacking cannot be carried out due to material jamming.

[0032] In this embodiment, the adjusting component 3 includes a number of adjusting grooves 301. An adjusting rod 302 is slidably installed inside the adjusting grooves 301, and a stacking limit post 6 is installed on the upper surface of each adjusting rod 302.

[0033] In this embodiment, a rotating groove 303 is opened in the middle of the lower surface of the platform 1. A rotating sleeve 304 is rotatably installed inside the rotating groove 303. A driving plate 305 is fixedly installed on the lower surface of the rotating sleeve 304. A number of limiting grooves 309 are opened on the surface of the driving plate 305, and the limiting grooves 309 are in limiting cooperation with the adjusting rods 302.

[0034] In this embodiment, a second motor 307 is fixedly installed on one side of the lower surface of the platform 1. A gear 308 is fixedly installed at the output end of the second motor 307. A tooth 306 is fixedly installed on the outside of the driving plate 305, and the tooth 306 is meshed with the gear 308.

[0035] By starting the second motor 307 to drive the gear 308 to rotate, and using the rotational cooperation between the rotating sleeve 304 and the rotating groove 303, the teeth 306 are engaged with the gear 308, and then the driving plate 305 rotates. During the rotation of the driving plate 305, the position of the limiting groove 309 changes, and due to the shape of the limiting groove 309, the adjusting rod 302 moves along the position of the limiting groove 309, and under the limitation of the rotating groove 303, the positions of multiple stacking limiting posts 6 are adjusted, so that the present application can be adjusted to the required nut size limit as needed, further enhancing the accuracy during nut stacking and avoiding poor stacking effects caused by chaotic nut sorting.

[0036] The working principle of the metal nut blanking and stacking device:

[0037] During use, first place the bracket 2 at the nut blanking port. When the nuts are blanked, they will approach the positioning post 4 under the guidance of the material guiding plate 9. By starting the first motor 506 to drive the eccentric wheel 504 to rotate, the bottom plate 503 swings under the connection of the transmission connecting rod 505, and then the connecting rod 402 swings inside the limiting ring 502, causing the entire positioning post 4 to be adjusted by a certain amplitude, so as to ensure that the nuts can be sleeved on the body of the positioning post 4.

[0038] During stacking, to prevent excessive position deviation between the nuts and make them inconvenient to pick up, by starting the second motor 307 to drive the gear 308 to rotate, and using the rotational cooperation between the rotating sleeve 304 and the rotating groove 303, the teeth 306 are engaged with the gear 308, and then the driving plate 305 rotates. During the rotation of the driving plate 305, the position of the limiting groove 309 changes, and due to the shape of the limiting groove 309, the adjusting rod 302 moves along the position of the limiting groove 309, and under the limitation of the rotating groove 303, the positions of multiple stacking limiting posts 6 are adjusted, so that the moving distance between the nuts is limited, avoiding the situation of excessive position deviation.

[0039] Obviously, the above embodiments of the present utility are merely examples for clearly illustrating the present utility, rather than limiting the implementation manners of the present utility. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present utility still fall within the protection scope of the present utility.
