Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to an adaptive screw processing feeding device. Background Technology

[0002] A screw is a common mechanical fastener, usually made of metal, with a threaded structure. It typically has a head and a threaded shank. Screws are usually used in conjunction with nuts to fasten two or more objects together by rotating them. Screws have a wide range of applications, from home renovation to mechanical engineering.

[0003] In existing technologies, vibratory feeders are mainly used to screen and feed screws. Two round rods are placed between the vibratory feeder and the processing device, and the gap between the rods is controlled to screen out unqualified screws. However, this method has certain drawbacks in actual use. For example, when the screws pass through the two round rods, they may get stuck between the rods due to size deviation, incorrect orientation, or excessive friction. This jamming will cause the feeding to be interrupted. Therefore, an adaptive screw processing feeding device is needed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adaptive screw processing feeding device.

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

[0006] An adaptive screw processing feeding device includes a vibratory feeder and a support. The discharge end of the vibratory feeder is connected to a guide rail, which is mounted on the upper end of the support. Two sets of air pipes are rotatably connected to the outer wall of the support and are connected to the ends of the guide rail. An electric telescopic rod is fixedly connected to the upper end of the support. A stop block is fixedly connected to the telescopic end of the electric telescopic rod, which extends into the interior of the two sets of air pipes. One set of air pipes has multiple through holes evenly spaced on its outer wall. A device cylinder is fixedly connected to the upper end of the support. An air guide pipe is installed on the outer wall of the device cylinder, and its other end is connected to the air pipe with through holes. A piston is slidably connected inside the device cylinder. A drive mechanism for driving the piston to slide is installed on the outer wall of the electric telescopic rod. A connecting pipe is fixedly connected to the outer wall of the device cylinder. One-way valves are installed in both the connecting pipe and the air guide pipe.

[0007] Preferably, the drive mechanism includes a connecting rod fixedly connected to the telescopic end of the electric telescopic rod, the other end of the connecting rod extending into the inside of the device cylinder and fixedly connected to the piston end face.

[0008] Preferably, the inner wall of the bracket is fixedly connected to two sets of side plates, and a double-threaded rod is rotatably connected between the two sets of side plates, and two sets of sliders are threadedly connected to the threaded section.

[0009] Preferably, both sets of sliders are rotatably connected to a connecting plate on their outer walls, and the connecting plate is rotatably connected to the adjacent air pipe.

[0010] Preferably, a limiting rod is fixedly connected between the two sets of side plates, and both sets of sliders are slidably connected to the outer wall of the limiting rod.

[0011] Preferably, a servo motor is fixedly connected to the outer wall of one of the side plates, and the end of the output shaft of the servo motor is coaxially fixedly connected to the double-threaded rod.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model precisely controls the screw feeding speed through the periodic extension and retraction of an electric telescopic rod, avoiding problems such as jamming or discontinuous feeding caused by feeding too fast or too slow. Simultaneously, the electric telescopic rod synchronously drives the piston to slide back and forth within the device cylinder via a connecting rod, compressing gas and injecting it into the air pipe through the air guide pipe. This creates a uniform airflow to assist screw sliding, thereby reducing friction between the screw and the air pipe. It also ensures that the screw can smoothly and continuously enter the processing position, effectively solving the jamming problem caused by excessive friction or insufficient airflow in traditional round rod screening methods.

[0014] 2. This utility model uses a servo motor to drive the double-headed threaded rod to rotate, which in turn drives two sets of sliders to move synchronously along the limit rod, precisely adjusting the tilt angle of the air tube, and can quickly adapt to the screening task of screws of different specifications.

[0020] 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.

[0021] Reference Figure 1-4 An adaptive screw processing feeding device includes a vibratory plate 1 and a support 2. The discharge end of the vibratory plate 1 is connected to a guide rail 3. The guide rail 3 is installed on the upper end of the support 2. Two sets of air pipes 4 are rotatably connected to the outer wall of the support 2 and are connected to the end of the guide rail 3. An electric telescopic rod 7 is fixedly connected to the upper end of the support 2. A stop block 14 is fixedly connected to the telescopic end of the electric telescopic rod 7 and extends into the interior of the two sets of air pipes 4. Multiple sets of through holes are opened at equal intervals on the outer wall of one set of air pipes 4. A device cylinder 6 is fixedly connected to the upper end of the support 2. An air guide pipe 5 is installed on the outer wall of the device cylinder 6 and the other end is connected to the air pipe 4 with through holes. A piston 16 is slidably connected inside the device cylinder 6. A drive mechanism for driving the piston 16 to slide is installed on the outer wall of the electric telescopic rod 7. A connecting pipe is fixedly connected to the outer wall of the device cylinder 6. A one-way valve is installed in both the connecting pipe and the air guide pipe.

[0022] Specifically, by using the sliding of piston 16, gas inside device cylinder 6 can be injected into air guide pipe 5. Combined with the through hole and one-way valve design on air pipe 4, airflow can be used to assist screw sliding, improving screening efficiency. It should be noted that the ends of the two sets of air pipes 4 are connected to the feed port of the screw processing device, thereby achieving the purpose of feeding the screened screws.

[0023] The drive mechanism includes a connecting rod 15 fixedly connected to the telescopic end of the electric telescopic rod 7, and the other end of the connecting rod 15 extends into the device cylinder 6 and is fixedly connected to the end face of the piston 16.

[0024] Specifically, the electric telescopic rod 7 directly drives the piston 16 through the connecting rod 15 to achieve synchronous control of airflow.

[0025] The inner wall of the bracket 2 is fixedly connected to two sets of side plates 8. A double-headed threaded rod 10 is rotatably connected between the two sets of side plates 8, and two sets of sliders 12 are threadedly connected to the threaded section. The outer walls of the two sets of sliders 12 are rotatably connected to a connecting plate 13, and the connecting plate 13 is rotatably connected to its adjacent air tube 4.

[0026] Specifically, the double-ended threaded rod 10 can realize the synchronous reverse movement of the two sets of sliders 12, precisely adjust the spacing of the air tube 4, and adapt to screws of different specifications.

[0027] A limiting rod 11 is fixedly connected between the two sets of side plates 8, and the two sets of sliders 12 are slidably connected to the outer wall of the limiting rod 11.

[0028] Specifically, the limiting rod 11 provides a stable guiding function for the slider 12, ensuring that the slider 12 will not deviate or tilt during movement.

[0029] One of the side plates 8 has a servo motor 9 fixedly connected to its outer wall, and the end of the output shaft of the servo motor 9 is coaxially fixedly connected to the double-threaded rod 10.

[0030] In this invention, the device is used as follows: the vibrating plate 1 starts working, arranging the screws in an orderly manner and conveying them through the guide rail 3 to the space between the two sets of air pipes 4. After the screws enter the air pipes 4, the operator can start the servo motor 9 according to the screw specifications. The servo motor 9 drives the double-headed threaded rod 10 to rotate, causing the two sets of sliders 12 to move synchronously along the limiting rod 11, thereby adjusting the tilt angle of the air pipes 4 to adapt to the task of screening screws of different specifications.

[0031] During the screening process, the screw feeding speed is controlled by periodically extending and retracting the electric telescopic rod 7. During this process, the piston 16 is driven to slide back and forth in the device cylinder 6 by the connecting rod 15. When the screw passes through the air pipe 4, the gas in the device cylinder 6 is compressed and enters the air pipe 4 through the air guide pipe 5, forming an airflow to assist the screw sliding. If the screw size does not meet the requirements, it will fall directly to prevent unqualified screws from entering the processing stage.

[0032] Through the coordinated work of the screening and feeding mechanisms, screws can enter the processing position efficiently and accurately, ensuring the continuity and stability of the processing process. The adaptive design of the device effectively solves the problems of jamming, insufficient accuracy and poor adaptability in the round rod screening method.

[0033] 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.
