[0022] The utility model is further described below in conjunction with embodiments.

[0023] See also Figure 1-5 The utility model provides a screw feeding mechanism, including a mounting cylinder 1 and a discharging cylinder 2, the discharging cylinder 2 is arranged at the bottom of the mounting cylinder 1, a feeding bin 101 is penetrated through the mounting cylinder 1 and the discharging cylinder 2, an adjusting mechanism 3 is arranged on the outside of the mounting cylinder 1 and the discharging cylinder 2, and a positioning mechanism 4 is arranged on the inside of the adjusting mechanism 3 between the mounting cylinder 1 and the discharging cylinder 2.

[0024] The adjustment mechanism 3 cooperates with the positioning mechanism 4 to facilitate adjustment according to screws of different specifications so as to carry out feeding work without replacing the device, thereby greatly improving the practicability of the device.

[0025] Further Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the adjustment mechanism 3 includes a rotating sleeve 301, which is movably mounted on the outside of the mounting cylinder 1 and the discharging cylinder 2. The inner side of the rotating sleeve 301 is fixedly connected to a limiting ring 302 near the upper part, and the limiting ring 302 is provided with a limiting groove 303 corresponding to the outer side of the mounting cylinder 1. A movable cavity 304 is provided between the inner side of the rotating sleeve 301 and the outer wall of the discharging cylinder 2. A thread 305 is provided on the inner surface of the rotating sleeve 301. An adjusting sleeve 306 is threadedly connected to the inner side of the rotating sleeve 301 through the thread 305. The size of the movable cavity 304 is matched with that of the adjusting sleeve 306. A tapered opening 3061 is opened through the adjusting sleeve 306, and an extrusion groove 3062 is opened on the tapered opening 3061 on the adjusting sleeve 306. The tapered opening 3061 is small at the top and large at the bottom.

[0026] By rotating the rotating sleeve 301, it is limited and rotated on the outside of the installation cylinder 1 and the discharge cylinder 2 through the limiting ring 302. Since the adjusting sleeve 306 is limited between the extrusion groove 3062 and the connecting frame 401, and the adjusting sleeve 306 is threadedly connected to the thread 305, the adjusting sleeve 306 slides in the movable cavity 304, and then the interval between the positioning mechanisms 4 is adjusted to adapt to the feeding of screws of different specifications.

[0027] According to the above working process, it can be known that: through the setting of the adjustment mechanism 3, when feeding screws of different specifications, the positioning mechanism 4 can be adaptively adjusted according to their specifications to facilitate the feeding work, thereby improving the practicability of the device.

[0028] Further Figure 2 , Figure 3 and Figure 5 As shown, it is worth explaining in detail that the positioning mechanism 4 includes three connecting frames 401, and the three connecting frames 401 are evenly arranged between the mounting cylinder 1 and the discharging cylinder 2 and are connected to each other. The connecting frame 401 matches the extrusion groove 3062, and an adjusting block 402 is arranged in the connecting frame 401. The upper part of the adjusting block 402 is fixedly connected to a reset shaft 403 and is arranged in the connecting frame 401. The adjusting block 402 is provided with a movable groove 404 near the bottom, and a positioning block 405 is slidably arranged in the movable groove 404. The positioning block 405 is installed with a spring 406 in the movable groove 404. The side of the adjusting block 402 close to the adjusting sleeve 306 is inclined and matches the tapered mouth 3061. The height of the adjusting block 402 is set greater than the distance that the adjusting sleeve 306 moves on the thread 305.

[0029] The adjusting block 402 is squeezed through the tapered mouth 3061 to move to the center of the feeding bin 101, thereby reducing the gap of the feeding bin 101 so as to feed screws of different specifications. Furthermore, through the setting of the reset shaft 403, when recovery is required, the rotating sleeve 301 is rotated in the reverse direction to facilitate the recovery of the adjusting block 402, thereby improving the practicability of the device.

[0030] This scheme has the following working process: when this device is used, the device is matched and installed with the electric screwdriver and the screw conveying device through the installation cylinder 1. At this time, the screw falls into the device through the feeding bin 101, and is limited in the vertical direction by the spring 406, and is pushed out by the electric screwdriver. When the specifications of the conveyed screws change, there is no need to replace the device at this time. By rotating the rotating sleeve 301, it is limited and rotated outside the installation cylinder 1 and the discharge cylinder 2 through the limiting ring 302. Since the adjusting sleeve 306 is connected to the connecting sleeve 306 through the extrusion groove 3062 The frame 401 is limited, and the adjusting sleeve 306 is threadedly connected with the thread 305, so that the adjusting sleeve 306 slides in the movable cavity 304, and then the adjusting block 402 is squeezed through the tapered mouth 3061 to move it in the center of the feeding bin 101, thereby reducing the gap of the feeding bin 101 to feed screws of different specifications, and through the setting of the reset shaft 403, when recovery is needed, the rotating sleeve 301 is rotated in the opposite direction to facilitate the recovery of the adjusting block 402, thereby improving the practicability of the device.

[0031] In summary: by setting up the adjusting mechanism 3, when feeding screws of different specifications, the positioning mechanism 4 can be adaptively adjusted according to their specifications to facilitate the feeding work, thereby improving the practicality of the device; by cooperating with the adjusting mechanism 3, the positioning mechanism 4 can be adjusted quickly and conveniently, thereby improving the working efficiency of the device.
