[0017] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0018] like Figure 1 to Figure 2 As shown, in this embodiment, a high-efficiency feeding mechanism includes a base plate 1, a feeding cylinder 2, a positioning cylinder 3 and a conveying track. The conveying track is located in the middle of the rear end of the base plate 1, and the feeding cylinder 2 is horizontally installed on one side of the base plate 1. A moving frame 4 is connected to the driving end of the feeding cylinder 2, and a feeding slider 5 is fixed to the lower end of the moving frame 4. A feeding slide rail 6 is arranged on one side of the conveying track. The feeding slide rail 6 is fixed on the base plate 1, and the feeding slider 5 is slidably connected to the feeding slide rail 6. The positioning cylinder 3 is fixed on the moving frame 4, and a positioning pin 7 is vertically downwardly connected to the driving end of the positioning cylinder 3. A slide groove 8 is arranged on the inner side of the conveying track, and the positioning pin 7 points to the slide groove 8.

[0019] The efficient feeding mechanism can be installed at any position where the material belt needs to be moved. The material belt is fed into the conveying track from the front, and the positioning cylinder 3 controls the positioning pin 7 to move downward, and the positioning pin 7 is inserted into the material hole on the front side of the material belt. Then, when the positioning cylinder 3 does not move, the feeding cylinder 2 controls the moving frame 4 to move backward, driving the positioning cylinder 3 to move to the rear end of the conveying track. At the same time, the positioning pin 7 pulls the material belt to move one station in the conveying track. During the movement of the moving frame 4, the feeding slide rail 6 and the feeding slider 5 are used to guide and reduce friction, thereby improving the accuracy of the material belt being pulled. In addition, the positioning pin 7 needs to pass through the belt hole on the material belt. In order to avoid relative collision with the fixed conveying track, a slide groove 8 is added so that the lower end of the positioning pin 7 can move in the slide groove 8.

[0020] A stopper 9 is fixed to the rear end of the bottom plate 1 to block the forward movement of the movable frame 4. In order to prevent the movable frame 4 from moving beyond the expected distance, an additional stopper 9 is provided to block the movable frame 4 at the feasible limit position to meet the accuracy of pulling the material belt.

[0021] A loading track is arranged at the front end of the conveying track, and the middle part of the loading track is in the same straight line as the middle part of the conveying track. The loading track and the conveying track are correspondingly combined to ensure that the material belt can smoothly enter the conveying track.

[0022] The conveying track includes a fixed conveying track 10 and a movable conveying track 11, and the loading track includes a fixed loading track 12 and a movable loading track 13. The fixed conveying track 10 and the fixed loading track 12 are both fixed on the bottom plate 1, and the movable conveying track 11 and the movable loading track 13 are both installed with a width adjustment slider 14. A width adjustment slide rail 15 is fixed on the bottom plate 1, and the width adjustment slider 14 slides on the width adjustment slide rail 15. Moreover, the lower end of the movable conveying track 11 and the lower end of the movable loading track 13 are both fixed with an adjustment block 16, and the adjustment block 16 is provided with an adjustment slot 17 and a lock The fixing screw and the locking screw are threadedly connected to the base plate 1 after passing through the adjusting groove 17. In order to meet the needs of material belts of different widths and improve the applicability of the mechanism, the conveying movable rail 11 and the loading movable rail 13 can be moved together along the width-adjusting slide rail 15 to adjust the interval between the conveying movable rail 11 and the conveying fixed rail 10. At the same time, the interval between the loading movable rail 13 and the loading fixed rail 12 is also adjusted accordingly. After the adjustment is completed, tighten the locking screw at the current position of the adjusting groove 17 to fix the conveying movable rail 11 and the loading movable rail 13.

[0023] An anti-retreat cylinder 18 is installed at the rear end of the conveyor track. When the material belt moves to the rear end of the conveyor track, the anti-retreat cylinder 18 presses down on the material belt, and the positioning cylinder 3 rises and returns to its original position. The anti-retreat cylinder 18 can effectively prevent the material belt from being brought back.

[0024] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
