[0044] It can be known that on the basis of the above, in order to facilitate the material conveyed on the material conveying mechanism 6 to be conveyed to the fork 11 after being accelerated, as shown in FIG. Figure 10-12The feeding mechanism 7 provided by the present invention includes a mounting frame 70, a driving roller 72 and a driven roller 71 are respectively mounted at both ends of the mounting frame 70, a conveying motor 73 for driving the driving roller 72 to rotate is mounted at one end of the mounting frame 70, and a conveying belt 74 is sleeved between the driving roller 72 and the driven roller 71, and four baffles 741 are arranged at equal intervals on the conveying belt 74; two groups of baffle sensing mechanisms with the same structure are arranged in the lower direction of the conveying belt 74; a fixed rod 75 is fixed on both sides of the mounting frame 70, and the baffle sensing mechanism includes two vertical rods 751 fixed on the fixed rod 75, and a cross rod 781 is rotatably connected between the two vertical rods 751, and a sensing plate 78 cooperating with the baffle 741 is installed on the cross rod 781. In a non-stressed state, the sensing plate 78 is vertical. The induction plate 78 is in a straight shape, and a rectangular plate A76 is connected between the two fixing rods 75 below the induction plate 78. The upper surface of the rectangular plate A76 is connected to the rectangular plate B761 through an elastic telescopic member, and the opposite sides of the rectangular plate B761 and the rectangular plate A76 are provided with pressure sensors and elastic touch rods that cooperate with each other; when the induction plate 78 is in a vertical shape, one side of the induction plate 78 abuts against the upper surface of the rectangular plate A76, and the pressure sensor detects a pressure signal at this time; when the baffle 741 abuts against one side of the top of the induction plate 78 and drives the induction plate 78 to deflect, one side of the induction plate 78 is detached from the upper surface of the rectangular plate A76, and the pressure sensor detects that the pressure signal disappears. The two baffle sensing mechanisms are arranged to facilitate the detection of the position of the baffle 741, that is, Fig.12 As shown, when the baffle 741 controls the pressure signal detected by the right pressure sensor to change from presence to absence, it is determined that the baffle 741 falls between the two baffle sensing mechanisms; at this time, the material on the material conveying mechanism 6 can be transported to the loading mechanism 7, and at this time, a material originally on the loading mechanism 7 is transported to the fork 11.

[0045] At the same time, when in use, the feeding mechanism 7 is used to accelerate the material on the material conveying mechanism 6 and transport it to the fork 11. After the material enters the fork 11, it is affected by the friction generated by the contact between the bottom of the material and the fork 11. The material entering the fork 11 may continue to move along the supporting surface of the fork 11 and fall off the supporting surface of the fork 11. The material blocking mechanism 4 is installed on the panel 19 flush with the feeding mechanism 7.

A horizontal push plate 44 is connected to the electric slider D43. A vertical plate 45 extending downward is connected to the end of the horizontal push plate 44. A guide support block is provided on one side of the vertical plate 45. A rectangular slide groove cooperating with the guide support block is provided on one side of the mounting beam 40. When in use, the electric slider D43 is controlled to move. It moves along the guide rail C42, and then the material on the roller 41 can be pushed to the fork 11 for placement. At the same time, the existence of the horizontal push plate 44 makes it convenient to limit the movement of the material moved to the roller 41; and when in use, an infrared distance sensor is set on the side of the horizontal push plate 44 close to the feeding mechanism 7. In the initial state, the electric slider D43 is controlled to move to the end of the guide rail C42 away from the feeding mechanism 7. The distance of the material closest to the horizontal push plate 44 is detected by the infrared distance sensor, and then when the feeding mechanism 7 is used for feeding, it is determined whether there is material pushed onto the roller 41.
