The motor 35 is used for driving the rotating shaft 31 to rotate, so that the feeding plate 22 or the measuring plate 21 is not required to be manually moved to move in the feeding process towards the feeder, and the feeding process is easier.

As shown in FIG. 2, since the feeder is high, the feeding plate 22 may be lifted up to feed the material into the feeder, which increases the difficulty of feeding the material into the feeding device. Therefore, a limiting plate 15 is arranged between the feeding plate 22 and the measuring plate 21, and the limiting plate 15 is welded with the mounting rod 23. The lateral wall that benefit groove 11 was kept away from to limiting plate 15 and the lateral wall butt that measures board 21 and be close to benefit groove 11, and the lateral wall butt that benefit groove 11 was kept away from to limiting block 15 near benefit groove 11 and last flitch 22, and when measuring board 21 lower extreme when the bottom, the 15 lower extremes of limiting block is less than and measures board 21 upper end, and the 15 upper ends of limiting block are higher than and measure board 21 upper end.

The gap between the measuring plate 22 and the feeding plate 21 is filled by arranging the limiting block 15, and the ascending height of the feeding plate 21 can be increased, so that the feeding device can be fed into the feeder without lifting the feeding device.

As shown in fig. 4, since the capacities of different feeders are different, and the amount of material to be supplemented into the feeder is also different, in order to enable the supplementing device to supplement materials to feeders with different capacities, the upper end of the measuring plate 21 is detachably connected with a plurality of adjusting blocks 24 for adjusting the groove space between the second wedge-shaped surface 211 and the upper material plate 22, the lower ends of the adjusting blocks 24 are attached to the upper end of the upper material plate 22, and two side walls of the adjusting blocks 24 are respectively located on the same plane with two side walls of the measuring plate 21 close to and far from the supplementing trough 11. Fourth wedge face 241 has all been seted up to regulating block 24 upper end, and the one end downward sloping that supplementary groove 11 was kept away from to fourth wedge face 241, and the butt between the adjacent regulating block 24. Through setting up detachable regulating block 24 to the volume of the recess that forms between second wedge 211 and the material loading board 22 is adjusted, and then the quantity of the screw that gets into in the feeder is adjustable, makes the feed supplement device can feed the feeder of different capacity.

As shown in fig. 4, a plurality of rectangular mounting grooves 213 are formed in the upper end of the side wall of the measuring plate 21 close to the feeding plate 22, the mounting grooves 213 penetrate through the upper end surface of the measuring plate 21, the limiting rods 26 are welded on the side wall of the mounting groove 213 facing the feeding groove 11, and the bottom surface of the mounting groove 213 is horizontally arranged. The lower end of the adjusting block 24 is welded with a rectangular mounting block 25, the mounting block 25 is inserted into the mounting groove 213, and the outer wall of the mounting block 25 is attached to the inner wall of the mounting groove 213. The mounting block 25 all runs through towards the terminal surface of moisturizing groove 11 has with gag lever post 26 complex spacing groove 251, when the mounting block 25 is inserted in mounting groove 213, gag lever post 26 is inserted in the gag lever post 251. When the adjusting block 24 is installed, the installing block 25 is only required to be inserted into the installing groove 213 along the axis of the limiting rod 26, so that the limiting rod 26 is inserted into the limiting groove 251, and the adjusting block 24 is more convenient to install and detach.

As shown in fig. 4, when the screw is driven by the measuring plate 21 after the adjusting block 24 is separated from the measuring plate 21, the screw is caught in the mounting groove 213, thereby affecting the feeding of the screw. Therefore, the stopper 27 for filling the mounting groove 213 can be detachably connected in the mounting groove 213, the upper end surface of the stopper 27 is located on the same plane as the second wedge-shaped surface 211, the connecting hole 271 penetrates through the end surface of the stopper 27 facing the material supplementing groove 11, and when the stopper 27 is arranged in the mounting groove 213, the limiting rod 26 is inserted into the connecting hole 271. The mounting groove 213 is filled with the stopper 27, so that the mounting groove 213 does not affect the movement of the screw.

As shown in fig. 2, since the screw cannot automatically move toward the phase measuring plate 21 when the screw is placed on the guide plate 12, the screw still needs to be manually pushed. Therefore, the guide plate 12 is inclined, one end of the guide plate, which is close to the feeding groove 11, is inclined downwards, and when a screw placed on the guide plate 12 receives a downward force applied by gravity, the screw can move towards the measuring plate 21 along the guide plate 12 which is inclined, so that the screw does not need to be manually pushed to move towards the measuring plate 21.

As shown in fig. 2, since the measurement plate 21 cannot accurately grasp the position at which it stops during the downward movement, the upper end of the measurement plate 21 is lower than the end of the guide plate 12 inclined downward, causing the screw to fall from the gap between the guide plate 12 and the measurement plate 21. Therefore, the one end of the guide plate 12 inclined downwards is connected with an extension plate 13 which is vertically arranged by using a bolt, and the extension plate 13 is attached to the side wall of the measurement plate 21 far away from the material supplementing groove 11. The gap between the guide plate 12 and the measuring plate 21 is closed by the extension plate 13, so that screws are not easy to fall from the gap between the guide plate 12 and the measuring plate 21, and the use of the material supplementing device is more stable.

As shown in fig. 1, since there is a gap between the box 1 and the feeder, the screw may fall to the bottom surface after passing through the replenishing groove 11. Therefore, the side wall of the box body 1, which is provided with the material supplementing groove 11, is connected with a U-shaped blanking hopper 14 by using bolts, and the notch of the blanking hopper 14 is communicated with the material supplementing groove 11. The lower end of the inner wall of the blanking hopper 14 intersects with the lower end of the feed trough 11, and two side walls in the vertical direction of the blanking hopper are in the same plane with the side walls in the vertical direction of the feed trough 11. The movement of the screws is guided by the blanking hopper 14, so that the screws are not easy to drop to the ground in the process of entering the feeder from the feeding tank 11.

The working principle is as follows:

when the feeder is supplemented with materials, the motor 35 is started, the motor 35 drives the rotating shaft 31 to rotate, so that the measuring plate 21 moves upwards, the feeding plate 22 moves downwards, in the upward movement process of the measuring plate 21, screws in a groove formed between the second wedge-shaped surface 211 and the feeding plate 22 move to the upper end of the limiting plate and then move to the upper end of the feeding plate 22, the motor 35 is controlled to rotate reversely, the feeding plate 22 rises to enable the measuring plate 21 to descend, and at the moment, screws between the first wedge-shaped surface 221 and the inner wall of the box body 1 move towards the material supplementing groove 11 under the guide of the first wedge-shaped surface 221, so that the screws enter the feeder through the blanking hopper 14.

The specific embodiments are only for explaining the present invention, and the present invention is not limited thereto, and those skilled in the art can make modifications without inventive contribution to the present embodiments as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
