Description

Technical Field

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

[0002] A feeder, also known as a material feeder, is a machine that, in the production process, uniformly, regularly, and continuously feeds lumpy or granular materials from a storage bin to a receiving device. Feeders are also used in screw production, simultaneously delivering screws to automatic screw fastening machines or assembly platforms through multiple independent channels, achieving efficient and precise material supply. It supports multi-axis synchronous operation, significantly improving production efficiency.

[0003] A search revealed Chinese Patent Publication No. CN214652109U, which discloses a multi-channel screw feeding device. The device includes a body and a feeding main body mounted on one end of a base. The upper end of the feeding main body has a feeding channel. A support base is installed at the lower end of the base and the feeding main body. A buffer spring is fixedly connected to the lower end of a buffer main body, with one end fixedly connected to the bottom plate of the base cavity. A through hole is opened at the upper end of the buffer plate, leading to a sound-absorbing plate fixedly connected to the lower end of the buffer plate. When the feeding machine operates, causing the feeding plate to vibrate, the buffer plate, being made of rubber, can alleviate the vibration to a certain extent. The elasticity of the buffer spring provides a reaction force to the feeding plate, offsetting most of the vibration, thus reducing the vibration of the feeding plate. This reduces the collision between the screws on the feeding plate and the plate, achieving noise reduction. The combined use of the through hole and the sound-absorbing plate further reduces noise.

[0004] In the aforementioned utility model, screw debris or dust easily accumulates in the gaps between the through holes, buffer plate, and sound-absorbing plate, making cleaning difficult. This may block the channels or interfere with the normal falling of screws, reducing feeding efficiency. Therefore, it is necessary to provide a direct multi-channel screw feeding device to improve feeding efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-channel screw feeding device to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a multi-channel screw feeding device, comprising:

[0007] A base and a feeding frame, wherein the feeding frame is fixed to one side of the upper surface of the base;

[0008] The feeding assembly includes an inclined chute, a feeding port, a circular groove, and an electric push rod. The inclined chute is opened on the inner bottom surface of the feeding frame. There are five feeding ports, which are equally spaced on one side of the feeding frame. The circular groove is opened on the bottom surface of the feeding frame, and the electric push rod is fixed in the corresponding circular groove.

[0009] Furthermore, a lifting frame is fixed to the top of the electric push rod, and an arc-shaped groove is provided on the inner wall of the lifting frame.

[0010] Furthermore, the base is provided with five feeding pipes, and an installation groove is provided on one side of each feeding pipe.

[0011] Furthermore, a spring is fixed inside the mounting groove, and a connecting pipe is fixed to one end of the spring.

[0012] Furthermore, one side of the connecting pipe contacts the outer surface of the feeding frame, and the connecting pipe corresponds to the feeding port.

[0013] Furthermore, it also includes a support assembly, which includes a fixed frame, a connecting shaft, and a connecting frame. There are five fixed frames, which are fixed to the upper surface of the base. The connecting shaft passes through the outer surface of the fixed frame and is rotatably connected to the outer surface of the feed pipe. There are five connecting frames, which are fixed inside the corresponding fixed frames.

[0014] Furthermore, a rotating shaft runs through the interior of the connecting frame, and a rotating rod rotates through the outer surface of the rotating shaft.

[0015] Furthermore, a locking block is fixed to the lower surface of the feeding tube, and the end of the rotating rod is locked into the corresponding locking block.

[0016] This utility model has the following beneficial effects:

[0017] This utility model's base, feeding frame, and feeding assembly, when feeding screws, activate an electric push rod via an external controller. The electric push rod drives the lifting frame to move up and down. When the lifting frame moves downward, the screw falls into the lifting frame. When the lifting frame moves upward to the feeding port, guided by the arc-shaped groove, the screw slides into the feeding port through the arc-shaped groove. Then, connected by the connecting pipe, the screw slides out of the feeding pipe. By combining the controllability of the electric push rod with the stability of the mechanical guide, the problem of jamming in traditional vibrating feeders is solved. The lifting frame and arc-shaped groove have an open structure, making it easy to observe whether there is screw debris accumulation inside, and cleaning does not require disassembling complex components.

[0027] 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.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this utility model is a multi-channel screw feeding device, comprising:

[0030] The base 11 and the feeding frame 12 are fixed to one side of the upper surface of the base 11;

[0031] The base 11 is used to support all components and provide a stable installation platform. The feed frame 12 provides a temporary storage area for screws and guides the screws to move along a predetermined path through its own structure.

[0032] The feeding assembly includes a chute 21, a feeding port 22, a circular groove 23, and an electric push rod 24. The chute 21 is opened on the inner bottom surface of the feeding frame 12. There are five feeding ports 22, which are equally spaced on one side of the feeding frame 12. The circular groove 23 is opened on the bottom surface of the feeding frame 12. The electric push rod 24 is fixed in the corresponding circular groove 23.

[0033] The inclined groove 21 uses gravity to make the screws slide naturally downwards and gather near the feeding port 22, avoiding the accumulation of screws in the frame. Each feeding port 22 corresponds to a feeding channel, realizing multi-channel parallel feeding and improving efficiency. The circular groove 23 provides installation space for the electric push rod 24, which is vertically fixed to the bottom surface of the feeding frame 12, ensuring the stability of the extension and retraction direction of the electric push rod 24. The electric push rod 24 is driven by an external controller and drives the lifting frame 25 to move up and down through the extension and retraction movement. The model of the electric push rod is LA12.

[0034] The top of the electric push rod 24 is fixed with a lifting frame 25, and the inner wall of the lifting frame 25 is provided with an arc groove 26. The base 11 is provided with five feeding pipes 27. One side of the feeding pipe 27 is provided with an installation groove 28. A spring 29 is fixed inside the installation groove 28. One end of the spring 29 is fixed with a connecting pipe 291. One side of the connecting pipe 291 is in contact with the outer surface of the feeding frame 12, and the connecting pipe 291 corresponds to the feeding port 22.

[0035] When the lifting frame 25 descends, it sinks into the pile of screws in the feeding frame 12 to accommodate a certain number of screws. When the lifting frame 25 rises to the height of the feeding port 22, the arc-shaped groove 26 guides the screws with its arc-shaped surface. The feeding pipe 27 guides the screws sent from the feeding port 22 to the downstream equipment. The mounting groove 28 is used to accommodate the spring 29 and the connecting pipe 291, providing expansion space for the connecting pipe 291. The spring 29 presses the connecting pipe 291 tightly against the outer surface of the feeding frame 12 through its own elasticity.

[0036] Working principle:

[0037] When feeding screws, the electric push rod 24 is activated by the external controller. The electric push rod 24 drives the lifting frame 25 to move up and down. When the lifting frame 25 moves down, the screw falls into the lifting frame 25. When the lifting frame 25 moves up to the feeding port 22, the screw slides into the feeding port 22 under the guidance of the arc groove 26. Then, with the connection of the connecting pipe 291, the screw slides out from the feeding pipe 27.

[0038] This step, by combining the controllability of the electric push rod 24 with the stability of the mechanical guide, not only solves the problem of material jamming in traditional vibratory feeders, but also makes it easy to observe whether there is screw debris accumulation inside by using the open structure of the lifting frame 25 and the arc groove 26, and does not require disassembly of complex components during cleaning.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The support assembly includes a fixed frame 31, a connecting shaft 32, and a connecting frame 33. There are five fixed frames 31, which are fixed to the upper surface of the base 11. The connecting shaft 32 passes through the outer surface of the fixed frame 31 and is rotatably connected to the outer surface of the feed pipe 27. There are five connecting frames 33, which are fixed inside the corresponding fixed frame 31.

[0041] The fixed frame 31 serves as the mounting base for the support components and provides lateral restraint to the feed tube 27, preventing it from shifting laterally when conveying screws or adjusting angles, thus ensuring the overall structural stability. The connecting shaft 32 allows the feed tube 27 to rotate up and down around the connecting shaft 32, thereby adjusting the tilt angle. The connecting frame 33 restricts the range of motion of the rotating rod 35, ensuring that it can only rotate within a preset trajectory, thus ensuring the accuracy of angle adjustment.

[0042] A rotating shaft 34 passes through the inside of the connecting frame 33, and a rotating rod 35 passes through the outer surface of the rotating shaft 34. A locking block 36 is fixed on the lower surface of the feeding pipe 27, and the end of the rotating rod 35 is locked into the corresponding locking block 36.

[0043] The rotating rod 35 swings freely around the rotating shaft 34, providing a movement path for its end to engage with different locking blocks 36. When the rotating rod 35 is manually rotated, its end can engage with locking blocks 36 at different positions on the lower surface of the feeding tube 27, and the feeding tube is fixed at the corresponding angle by leverage. The locking blocks 36 at different positions correspond to different tilt angles of the feeding tube 27.

[0044] Working principle:

[0045] When feeding screws, the feed tube 27 can be adjusted according to the synchronous processing line to adjust the feeding speed of the screws. Rotating the feed tube 27 and then rotating the rotating rod 35 will cause the end of the rotating rod 35 to be locked into different locking blocks 36 to adjust the inclination of the feed tube 27.

[0046] This step achieves stepless control of the feeding speed through mechanical adjustment, which not only meets the collaborative needs of different processing rhythms, but also accommodates the conveying characteristics of screws of various specifications. At the same time, it maintains the advantages of simple structure and convenient operation, making it particularly suitable for flexible production lines and effectively improving the overall utilization rate and production stability of the equipment.

[0047] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
