[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] Example 1

[0018] See Figures 1 to 4As shown, the screw processing feeding device involved in this embodiment includes a frame 1, on which a bar stock bin 2 is provided. The bar stock bin 2 has a bar stock inlet 201 at the top and a bar stock outlet 202 at the bottom. The bar stock outlet 202 extends horizontally back and forth. A take-up roller 3 located directly below the bar stock outlet is rotatably connected to the frame 1. One end of the take-up roller 3 is drivenly connected to a power assembly 4 for controlling its rotation. The power assembly 4 includes a geared motor fixedly connected to the frame 1. The roller surface of the take-up roller 3 has three take-up grooves 301 arranged in a circular array around an axis. The grooves of the take-up grooves 301 are adapted to the bar stock outlet 202. The feeding roller 3 has a feeding platform 5 located on its lower right side. The feeding platform 5 has a limiting hole 6 that extends horizontally back and forth. A limiting plate 7 is slidably connected inside the limiting hole 6. The feeding platform 5 has two baffles 8 located on the left and right sides of the limiting hole, respectively. The baffles 8 are angle steels that extend back and forth. A pusher 9 connected to the limiting plate is located between the two baffles 8. The pusher 9 is a cylindrical structure with its axis extending horizontally back and forth. A rodless cylinder 10 that extends back and forth is located below the feeding platform 5. The limiting plate 7 is fixedly connected to the slide of the rodless cylinder 10. The front end of the frame 1 has a feeding port 11 located directly in front of the pusher 9.

[0019] Furthermore, the included angle between two adjacent material-taking grooves 301 is equal.

[0020] In this embodiment, a batch of metal bars to be processed is placed in the bar stock bin 2. The metal bars move downwards with gravity, and the bottom metal bars are discharged from the bar outlet 202. During this period, the power assembly 4 controls the picking roller 3 to rotate at a constant speed. When rotating, the metal bars discharged from the bar outlet 202 will fall into a picking groove 301. When the picking roller 3 continues to rotate, it will discharge the metal bars in the groove and discharge them between the two baffles 8. During the time interval when the two adjacent picking grooves 301 switch positions, the rodless cylinder 10 completes one reciprocating motion, causing the pusher 9, which was originally located behind the workpiece, to move towards the discharge port 11, so as to push the metal bars discharged between the two baffles 8 out of the discharge port 11, thereby realizing the automatic feeding function.

[0021] Example 2

[0022] See Figures 1 to 4 As shown, the screw processing feeding device involved in this embodiment is further configured, based on embodiment 1, that the bottom of the bar stock bin 2 has a guide slope 203 that is inclined to the left and right, and the end of the guide slope 203 near the bar stock outlet is lower than the end away from the bar stock outlet.

[0023] In this embodiment, the material guide slope 203 makes the output of raw materials added to the bar stock hopper 2 smoother.

[0024] The screw processing feeding device involved in this utility model realizes intermittent material discharge from the bar stock bin through a rotating feeding roller. With the help of the linkage pusher, it can realize the function of automatic uniform material discharge from the discharge port. It is used for automatic bar stock feeding, with stable feeding, complete overall functions, and strong practicality.
