This technology protects the base material from the erosion of the external environment by covering a layer of cadmium on the steel surface.

[0003] Bolts are common fasteners. The main purpose of cadmium plating bolts is to enhance their rust prevention performance. When plating a large number of bolts with cadmium, a feeding mechanism is required to transport the bolts. In the prior art, most feeding mechanisms lack components for positioning the bolts during the transportation and feeding process of the bolts, resulting in the problem of bolts falling during the transportation and feeding process, thus affecting the efficiency of cadmium plating of bolts through automatic feeding and having insufficient practicability. Therefore, it is necessary to redesign the automatic feeding mechanism of the cadmium plating production line for the above problems. Summary of the Utility Model

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-5 , the automatic feeding mechanism of the cadmium plating production line, including a transportation frame 1. Two transportation rollers 2 are rotatably installed inside the transportation frame 1. A transportation belt 3 is installed on the outer walls of the two transportation rollers 2. A plurality of placement grooves are provided on the outer wall of the transportation belt 3. A feeding hopper 5 is fixedly installed on the upper end surface of the transportation frame 1 through a fixing mechanism. The fixing mechanism includes two fixed rods 4 fixedly installed on the upper end surface of the transportation frame 1. The ends of the two fixed rods 4 are fixedly connected to the outer wall of the feeding hopper 5. A first support plate 6 is fixedly installed on the upper end surface of the transportation frame 1. A connecting frame 8 is fixedly installed on the bottom wall of the first support plate 6 through a lifting mechanism. The lifting mechanism includes a cylinder 7 fixedly installed on the bottom wall of the first support plate 6. The telescopic end of the cylinder 7 is fixedly connected to the upper end surface of the connecting frame 8. A retaining roller 9 is rotatably installed inside the connecting frame 8. Two stabilizing rods 10 are slidably installed through the upper end surface of the first support plate 6. The ends of the two stabilizing rods 10 are fixedly connected to the upper end surface of the connecting frame 8.

[0023] A double-headed screw 11 is rotatably installed inside the transportation frame 1. A motor 12 connected to the double-headed screw 11 is fixedly installed on the outer wall of the transportation frame 1. Two moving sleeves 14 are threadedly rotated on the outer wall of the double-headed screw 11. A limiting rod 13 is fixedly installed inside the transportation frame 1. The limiting rod 13 slidably penetrates through the two moving sleeves 14. The limiting rod 13 can limit the two moving sleeves 14, so that the two moving sleeves 14 can only axially move along the outer wall of the double-headed screw 11. The upper end surfaces of the two moving sleeves 14 are fixedly connected to a positioning plate 16 through a connecting mechanism. The connecting mechanism includes a connecting rod 15 fixedly installed on the upper end surface of the moving sleeve 14. The end of the connecting rod 15 is fixedly connected to the outer wall of the positioning plate 16. A drying blower 18 is fixedly installed on the upper end surface of the transportation frame 1 through a second support plate 17.

[0024] When the utility model is in use, the bolt after flushing and cleaning can be placed inside the feeding hopper 5. At this time, the bolt can fall inside the feeding hopper 5 above the conveying belt 3. Subsequently, the two conveying rollers 2 can drive the conveying belt 3 to rotate, so that the conveying belt 3 can drive multiple bolts to move. During this process, the cylinder 7 can drive the blocking roller 9 to move downward through the connecting frame 8. The connecting frame 8 can drive the two stabilizing rods 10 to slide on the bottom wall of the first support plate 6. Through the blocking of the blocking roller 9, multiple stacked bolts can be respectively moved into multiple placing grooves on the outer wall of the conveying belt 3, so that the conveying belt 3 can transport and feed the bolts through the placing grooves;

[0025] Meanwhile, the motor 12 can drive the double-headed screw rod 11 to rotate. When the double-headed screw rod 11 rotates, it can drive the two moving sleeves 14 to move through the cooperation with the limiting rod 13. The two moving sleeves 14 respectively drive the two positioning plates 16 to move through the cooperation with the connecting rods 15, so that the two positioning plates 16 can approach each other to clamp and position multiple bolts, avoiding the bolts from falling out of the placing grooves during the transportation and feeding process. And during transportation, the drying fan 18 can blow and dry the bolts through the cooperation of the air blowing pipe 19 and the air blowing opening, so as to avoid the influence of the moisture of the bolts after flushing and cleaning on their subsequent cadmium plating effect.

Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
