[0021] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] See also Figure 1-4 The utility model provides a feeding device for pliers processing, comprising a shell 1 with an opening at the top, a discharge port 2 being provided on one side of the shell 1, two synchronous wheels 3 being symmetrical and rotatable are arranged in the shell 1, a synchronous belt 4 is wound between the two synchronous wheels 3 through tooth grooves, a plurality of placement blocks 5 which are evenly spaced and concave in structure are fixedly connected to the surface of the synchronous belt 4, and two limit rods 6 which are symmetrical in the left and right axial directions and can move in opposite directions are also provided in the shell 1. Through such a design, the workpieces which need to be transferred can be The pliers are inserted into the placement block 5 with the jaws facing upward, and the inner sides of the two handles of the pliers can be placed on the two limit rods 6 respectively to keep the pliers stable, and the synchronous wheel 3 can drive the synchronous belt 4 to rotate, so that the pliers on the placement block 5 can move toward the discharge port 2, and finally fall out of the housing 1 from the discharge port 2 to complete the quick transfer and feeding of the pliers, and the two limit rods 6 can adjust the spacing according to the different models and specifications of the pliers to adapt to different sizes of pliers handles for use, so that the device has high applicability.

[0023] Specifically, two left-right symmetrical mounting frames 7 are fixedly connected to the bottom of the inner wall of the shell 1, and two synchronous wheels 3 are rotatably mounted on the two mounting frames 7 respectively. A servo motor 8 for driving the corresponding synchronous wheel 3 to rotate is fixedly mounted on the surface of one of the mounting frames 7. When the synchronous wheel 3 rotates, the other synchronous wheel 3 can be driven to rotate synchronously through the synchronous belt 4, and the rotation of the synchronous belt 4 will move multiple placement blocks 5 on its surface to complete the transfer of the pliers position on the placement block 5.

[0024] See also Figure 3A mounting plate 9 is fixedly connected to one side of the inner wall of the shell 1 along its width direction, and a slide groove 10 is opened on the surface of the mounting plate 9. Two symmetrical sliders 11 are slidably inserted in the slide groove 10, and one end of the two limit rods 6 is respectively fixedly connected to the surfaces of the two sliders 11, so that the two limit rods 6 can form a snap-fit ​​sliding connection along the width direction of the shell 1 in the shell 1. Such a design will be more reasonable.

[0025] In order to enable the two limit rods 6 to move toward or oppositely, in some embodiments, it is proposed that a bidirectional threaded rod 12 is rotatably connected in the slide groove 10 through a bearing, and the two sides of the surface of the bidirectional threaded rod 12 are respectively inserted into the two sliders 11 through the cooperation of the forward thread and the reverse thread, and the housing 1 is provided with a rotating mechanism for rotating the bidirectional threaded rod 12. When the bidirectional threaded rod 12 rotates, the two sliders 11 slide toward or oppositely along the slide groove 10 through the cooperation of the forward thread and the reverse thread, so as to realize the adjustment of the distance between the two limit rods 6, which is convenient for adapting to the distance between the two handles of the corresponding pliers.

[0026] Furthermore, the rotating mechanism includes a rotating shaft 13 which is rotatably plugged into one side of the housing 1 through a bearing, one end of the rotating shaft 13 is fixedly connected to a driving bevel gear 14, one end of the bidirectional threaded rod 12 passes through the mounting plate 9 and is fixedly connected to a driven bevel gear 15 which meshes with the driving bevel gear 14, and a driving member for driving the rotating shaft 13 to rotate is provided on the housing 1. When the rotating shaft 13 rotates, it will drive the driving bevel gear 14 to rotate, so that the driving bevel gear 14 can drive the driven bevel gear 15 to rotate through tooth matching, and achieve the effect of rotating the bidirectional threaded rod 12.

[0027] Meanwhile, the driving member includes a servo motor 16 fixedly mounted on one side of the housing 1. The output shaft end of the servo motor 16 is fixed to one end of the rotating shaft 13. When the output shaft of the servo motor 16 rotates, the rotating shaft 13 can be driven to rotate.

[0028] On the other hand, if the pliers dropped from the discharge port 2 are not taken away for processing in time, accumulation may occur, thereby affecting the feeding of subsequent pliers. To avoid the above problem, a bottom plate 17 is fixedly connected to the bottom of the shell 1, and one side of the bottom plate 17 is fixedly connected to a receiving box 18 located below the discharge port 2 and used to receive the pliers dropped from the discharge port 2, and the bottom of the inner wall of the receiving box 18 is inclined, so that the pliers dropped from the discharge port 2 will fall into the receiving box 18 for collection, and can slide downward along the bottom of the receiving box 18 to avoid accumulation directly below the discharge port 2.

However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0030] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
