Description

Technical Field

[0001] This utility model relates to the field of screw feeding and sorting technology, specifically to a screw feeding and sorting device. Background Technology

[0002] Screws are common fasteners or connectors, usually made of metal, used to connect and fix two or more objects. Screws have a wide range of applications, including furniture manufacturing, construction engineering, machinery manufacturing, the automotive industry, and electronic equipment. In screw processing, screws need to be loaded onto the processing equipment. A search revealed an existing technology (publication number: CN202322649666.7) for a screw loading and sorting device. The description states that "screws requiring surface treatment are poured into the loading hopper, the loading rack is opened, and the screws in the loading hopper are transported in batches to the turntable. Adjusting the position of the two sliding blocks on the aluminum alloy profile changes the curvature of the first aluminum plate. Then, adjusting the position of the limiting shaft within the stroke hole and fixing the limiting shaft by hand-tightening the nut changes the screw discharge rate of the turntable." However, this existing technology faces the problem of difficulty in sorting out screws of different specifications mixed in with the screws loaded into the loading hopper. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a screw feeding and sorting device is provided to solve the problem that it is difficult to sort out screws of different specifications mixed in with the screws when feeding screws into the hopper in the existing technology.

[0004] To achieve the above objectives, a screw feeding and sorting device is provided, comprising: a screw feeding bin, wherein a feeding mechanism is distributed at the lower end of the screw feeding bin.

[0005] The screw feeding bin has a storage chamber and a sorting chamber inside. The sorting chamber wall is connected to a tilting plate via a bearing. A motor is connected to the left side shaft of the tilting plate. A first limiting plate and a second limiting plate are distributed at the lower end of the tilting plate. The left ends of the first limiting plate and the second limiting plate are connected to a driving block via a connecting block. A double-threaded screw is installed at the outer left side of the screw feeding bin. A driving block is connected to the surface of the double-threaded screw. A material holding frame is provided on the lower surface of the screw feeding bin.

[0006] Furthermore, the lower end of the screw feeding bin is supported by a feeding frame; and a feeding mechanism is installed inside the feeding frame, with a CNC panel and a central control cabinet fixed to the front end of the feeding frame.

[0007] Furthermore, a screw-specific vibratory feeder is provided on the right side of the feeding mechanism, a guide mechanism is installed on the upper surface of the screw-specific vibratory feeder, and a material conveying mechanism is provided on the right side of the screw-specific vibratory feeder.

[0008] Furthermore, a discharge baffle is sealed at the lower opening of the storage chamber; and the sorting chamber is located at the lower end of the storage chamber, with the rear end of the discharge baffle connected to the screw loading bin via an electric push rod.

[0009] Furthermore, a discharge port is provided on the lower end face of the screw feeding bin, and an electric push rod two is fixedly connected to the lower end of the screw feeding bin. The front side of the electric push rod two is inserted into the material holding frame through a fixing plate.

[0010] Furthermore, a distance sensor is embedded in the rear end face of the second limiting plate, and a motor is connected to the front end shaft of the double threaded screw.

[0011] Furthermore, the right side limiting sliding joints of the first limiting plate and the second limiting plate are located on the right side wall of the sorting cavity; and the second limiting plate and the first limiting plate are symmetrically distributed front and back.

[0012] The beneficial effects of this utility model are as follows: the screw feeding and sorting device of this utility model uses a double threaded screw to adjust the spacing between two sets of limiting plates in the screw feeding chamber to form a screw sorting slot, separating screws larger and smaller than the spacing value, so that the separated and falling screws fall to the holding frame or feeding mechanism. At the same time, the rotating plate rotates and pushes the batch of screws to move in the chamber, effectively avoiding the obstruction of feeding due to excessive screws, facilitating the quick sorting of screws of the required size and specifications from the batch of screws, simplifying the mechanical components of the screw feeding and sorting device, and improving the screw feeding and sorting efficiency.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4 As shown, this utility model provides a screw feeding and sorting device, including: a screw feeding bin 1, and a feeding mechanism 2 distributed at the lower end of the screw feeding bin 1.

[0020] The screw feeding bin 1 has a storage chamber 12 and a sorting chamber 14 inside. The sorting chamber 14 is connected to a rotating plate 4 via a bearing. A motor 41 is connected to the left side of the rotating plate 4. A first limiting plate 5 and a second limiting plate 55 are distributed at the lower end of the rotating plate 4. A drive block 51 is connected to the left end of both the first limiting plate 5 and the second limiting plate 55 via a connecting block 53. A double threaded screw 52 is installed at the outer left side of the screw feeding bin 1. The drive block 51 is connected to the surface of the double threaded screw 52. A material holding frame 6 is provided on the lower surface of the screw feeding bin 1.

[0021] First, adjust the distance between the first limiting plate 5 and the second limiting plate 55 so that screws smaller than the required size can pass through. A batch of screws is then poured into the screw loading hopper 1. As the unloading baffle 11 moves, some screws fall from the storage chamber 12 to the sorting chamber 14. The rotating plate 4 in the sorting chamber 14 rotates and flips the screws, moving multiple screws to the distance between the first limiting plate 5 and the second limiting plate 55. Screws passing through this distance fall into the holding frame 6. Then, adjust the distance between the first limiting plate 5 and the second limiting plate 55 so that screws of the required size can pass through. Move the holding frame 6 backward so that screws of this size can fall through the distance between the first limiting plate 5 and the second limiting plate 55 onto the loading mechanism 2. The loading mechanism 2 then transports the screws to the screw-specific vibrating plate 3. Finally, the vibration of the screw-specific vibrating plate 3 arranges the disordered screws neatly and transports them out in a specific direction.

[0022] In this embodiment, a feeding frame 23 is supported at the lower end of the screw feeding bin 1; a feeding mechanism 2 is installed inside the feeding frame 23, and a CNC panel 21 and a central control cabinet 22 are fixed on the front end face of the feeding frame 23. A screw-specific vibratory feeder 3 is provided on the right side of the feeding mechanism 2, a guide mechanism 31 is installed on the upper surface of the screw-specific vibratory feeder 3, and a conveying mechanism 32 is provided on the right side of the screw-specific vibratory feeder 3.

[0023] As a preferred implementation, the feeding mechanism 2 facilitates the conveying of screws of the required size into the screw-specific vibratory feeder 3. The screw-specific vibratory feeder 3 causes the screws to gradually rise along a spiral track through vibration. During this rise, the guide mechanism 31 adjusts the screws' posture, ultimately arranging them neatly and conveying them to the conveying mechanism 32 (the screw-specific vibratory feeder 3 is existing equipment; its specific working principle and structure will not be elaborated upon here). This facilitates the neat feeding, sorting, and conveying of screws to the processing equipment, thereby accelerating subsequent processing or assembly efficiency.

[0024] In this embodiment, a discharge baffle 11 is used to seal the lower opening of the storage chamber 12; and the sorting chamber 14 is located at the lower end of the storage chamber 12. The rear end of the discharge baffle 11 is connected to the screw loading bin 1 via an electric push rod 13.

[0025] As a preferred implementation, the electric push rod 13 drives the discharge baffle 11 to move back and forth, so that the discharge baffle 11 is in a blocked or removed state. The discharge baffle 11 makes it easy to control the number of screws in the sorting cavity 14, and avoids that too many screws in the sorting cavity 14 will affect the sorting effect.

[0026] In this embodiment, a discharge port 15 is provided on the lower end face of the screw feeding bin 1, and an electric push rod 62 is fixedly connected to the lower end of the screw feeding bin 1. The front side of the electric push rod 62 is inserted into the material holding frame 6 through a fixing plate 61.

[0027] In a preferred embodiment, the discharge port 15 facilitates the discharge of screws at the distance between the first limiting plate 5 and the second limiting plate 55, allowing the discharged screws to fall into the material holding frame 6 or the feeding mechanism 2. The electric push rod 62 drives the material holding frame 6 to move back and forth, causing the material holding frame 6 to move to the discharge port 15 or move away from the discharge port 15.

[0028] In this embodiment, a distance sensor 54 is embedded in the rear end face of the second limiting plate 55, and a motor 56 is shaft-connected to the front end of the double threaded screw 52. The right side limiting sliding joints of the first limiting plate 5 and the second limiting plate 55 are located at the right side wall of the sorting cavity 14; and the second limiting plate 55 and the first limiting plate 5 are symmetrically distributed front and back.

[0029] In a preferred embodiment, the distance sensor 54 detects the distance between the first limiting plate 5 and the second limiting plate 55, facilitating the passage of screws of different sizes. The motor 56 controls the rotation of the double-threaded lead screw 52, ​​causing the drive block 51 to convert the rotational motion into linear motion, thereby driving the second limiting plate 55 and the first limiting plate 5 to move synchronously in opposite directions, achieving the effect of adjusting the distance between the second limiting plate 55 and the first limiting plate 5.

[0030] The screw feeding and sorting device of this utility model can effectively solve the problem in the prior art that it is difficult to sort out screws of different specifications mixed in with the screws when feeding screws into the hopper. It can effectively avoid the obstruction of feeding due to excessive screws, facilitate the quick sorting of screws of the required size and specifications from a batch of screws, simplify the mechanical components of the screw feeding and sorting device, improve the screw feeding and sorting efficiency, and is applicable to screw feeding and sorting devices.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
