Description

Technical Field

[0001] This utility model relates to the field of automatic nut feeding at multiple workstations, and in particular to an automatic nut feeding mechanism at multiple workstations based on material channel switching. Background Technology

[0002] The multi-station automatic nut feeding equipment uses a vibratory feeder as the core feeding component. Through vibration sorting, it organizes disordered nuts into a directional output state. The nuts are then stably transported to the distribution mechanism via the feeding track. The distribution component accurately distributes the nuts according to the needs of each station. Some mechanisms adopt a modular material channel design, combined with sensor detection and pneumatic pushing devices, to complete synchronous or sequential feeding of multiple stations, realizing the automated flow of nuts from feeding to the station.

[0003] A typical multi-station automatic nut feeding mechanism consists of a vibrating feeder, multi-station feed channels, a switching component, and a pushing device. The vibrating feeder sorts and feeds the nuts to the main feed channel, and the distribution mechanism distributes the nuts to the feed channels of each station. The feed channel switching component uses a cylinder to drive the slide rail to achieve the alignment and switching of the feed channels, adapting to nuts of different specifications. The pushing device is driven by a servo motor to push the push rod, accurately pushing the nuts in the corresponding feed channel to the assembly station. Sensors monitor the status of the feed channels in real time to ensure continuous automatic feeding.

[0004] In some existing devices, there is a problem of intermittent conveying when the material in the hopper decreases. When the remaining nut in the hopper is insufficient, the stability of the material supply in the channel decreases, which can easily lead to the pusher plate waiting for material and the material supply interruption caused by the lack of material in a single hopper when the material channel is switched. The pusher plate relies on the continuous material supply of the material channel. The decrease in material reduces the material channel filling rate, and the pusher plate is prone to empty push or half push when pushing, which causes uneven feeding intervals of subsequent stations, affects the continuity of the production line and processing efficiency, and increases the idle time of the equipment. To solve the above problems, a multi-station automatic nut feeding mechanism based on material channel switching is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-station automatic nut feeding mechanism based on material channel switching, which aims to improve the problem of material supply interruption in some existing devices.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when the light hopper is being filled, the storage plate slides down along the sliding groove, causing the connecting rod to swing forward around the connecting block 2 as the center. This pushes the connecting rod 2 forward through the hollow sliding groove 2 on the rotating column of the support frame, pulling the push plate back to its original position. When the material decreases, the spring pushes the storage plate upward, pulling the connecting rod 1 and connecting rod 2 upward. The connecting rod 2 then slides backward, pushing the push plate along the guide rail and the housing, ultimately moving the push plate close to the push block to complete the material conveying. This achieves automated control of the material conveying, automatically completing the push plate reset and pushing action according to the material weight change, ensuring that the material can be pushed more stably towards the push block when it decreases to the bottom, without any intermittent or uneven feeding, thus improving the continuity, reliability, and stability of the equipment operation.

[0025] 2. In this utility model, when the cover is opened for feeding, the handle drives the cover plate two to slide left and fold through the right-side track sliding roller. The bottom return rod swings down, causing the spring inside the torsion shaft to store energy. The locking hook is embedded in the housing locking structure to complete the opening. When closing, push the locking structure and pull the handle. The spring releases energy to assist in closing, thus realizing the smooth opening and closing of the cover plate two structure through the sliding roller. With the help of the return rod and the spring of the torsion shaft to store energy, the spring releases energy when closing, saving effort and requiring no additional power. It automatically completes energy storage and assistance with operation, improving the opening and closing efficiency and convenience of the feeding process, and enhancing the stability of the structure and the comfort of use.

[0042] Working principle: When the light hopper is filled, as the material increases, the storage plate 26 is pressed down. The front half of the storage plate 26 slides down along the sliding groove 28, pressing the connecting rod 256. The connecting block 255 swings forward from the center. The connecting rod 256 rotates and connects to the connecting rod 257, which slides forward. The hollow sliding groove 2510 inside the connecting rod 257 allows it to reciprocate on the central rotating column of the support frame 259 as the connecting rod 256 moves. At this time, the connecting rod 257 slides along the support frame 259 to the rear end of the sliding groove 2510, and at the same time pulls the push plate 27 forward to slide to the rear of the storage plate 26 and fit against it, completing the reset and fit of the push plate 27. When the equipment is in use, the material changes from heavy to light. As the downward pressure of the storage plate 26 gradually weakens, the bottom spring 251 pushes the storage plate 26 upward. 6. Then, connecting rod 1 256 and connecting rod 257 are pulled upward. Due to the rotational connection between connecting rod 1 256 and connecting rod 257, the hollow design of connecting rod 257 simultaneously pushes the push plate 27 backward on the support frame 259. When connecting rod 257 is pulled to the horizontal, the push plate 27 slides along the storage plate 26 and the housing 1 because the top of the front side is slidably connected to the guide rail of the storage plate 26 and the bottom side is slidably connected to the inside of the housing 1. At this time, the angle between the push plate 27 and the machine body 21 becomes smaller. Connecting rod 1 256 continues to be pulled diagonally upward and drives the horizontal connecting rod 257 upward. Connecting rod 257 slides on the central rotating column and continues to slide backward on its hollow bottom side until the storage plate 26 is pushed to the top of the sliding groove 28 by the spring 251 and stops. At this time, the push plate 27 and the push block 23 are close to the front, completing the continuous and stable conveying of materials.

[0043] During the loading process, cover plate 2 31 needs to be opened. At this time, pull handle 33 to the left. Cover plate 2 31 slides and folds to the left through the sliding roller 346 in the right track. The bottom drive return rod 342 swings downward and drives the spring 344 inside the compression torsion shaft 343 to store energy. When cover plate 2 31 slides to the left side of housing 1 and fits, the locking hook 32 is embedded in the inside of housing 1 and engages with its internal locking structure to complete the loading and opening of the compartment. When cover plate 2 31 is closed, push the push block of the locking structure to open the limit. Gently pull handle 33 and spring 344 to release the stored energy to help cover plate 2 31 close, so that cover plate 2 31 can be closed quickly and effortlessly.
