[0025] like Figure 2 This embodiment provides a long material lifting and conveying mechanism, which is correspondingly arranged at the lower part of the feeding mechanism 1. The feeding mechanism 1 includes a plurality of rollers 10 arranged in parallel and at intervals along a first direction A, and also includes a feeding rack 11. The rollers 10 are rotatably arranged on the feeding rack 11, and the direction in which the material is conveyed from the rollers 10 is defined as the first direction A.

[0026] Among them, Figure 3-Figure 5, is a lifting and conveying mechanism including a lifting module 2 and a conveying module 3. The lifting module 2 is arranged inside the feeding frame 11 and below the roller 10. The lifting module 2 and the conveying module 3 are connected by driving. Driven by the lifting module 2, the conveying module 3 is forced to extend from the area between adjacent rollers 10 to the top of the roller 10 in a lifting and lowering manner, and is used to receive materials conveyed from a first direction A and redirect the materials to be conveyed along a second direction B. The first direction A and the second direction B are perpendicular to each other on a horizontal plane. The lifting and conveying mechanism replaces the traditional single cylinder. The traditional single cylinder only has a single contact force on a long material, and the material may be pushed off-center. The conveying module 3 lifts the material, supports the whole material, and then conveys the whole material in the second direction B. Long materials or scattered materials can be conveyed reliably and stably.

[0027] In this embodiment, more specifically, the lifting and conveying mechanism also includes a support frame 4, the support frame 4 is fixed on the inner side of the feeding frame 11, the lifting module 2 is arranged on the support frame 4, and the conveying module 3 is arranged on the lifting module 2 and is driven by the lifting module 2 to rise and fall as a whole.

[0028] Secondly, the jacking module 2 includes a jacking cylinder 20, a jacking drive shaft 21, a crank 22 and a jacking frame 23;

[0029] The conveying module 3 is arranged on the jacking frame 23, and the jacking frame 23 is above the support frame 4. One end of the jacking cylinder 20 is hinged on the inner side of the support frame 4, and the other end output end is hingedly connected to the jacking drive shaft 21 through a crank 22. The two ends of the jacking drive shaft 21 are rotatably connected to the lower part of the support frame 4, and the jacking cylinder 20 is located on the center line of the support frame 4. At the same time, in order to keep the jacking frame 23 horizontal and lifted as a whole, a swing block 24 is further provided. Preferably, the cross-section of the swing block 24 is triangular, one swing block 24 is rotatably connected to the two ends of the jacking drive shaft 21, and the other swing block 24 is rotatably connected to the lower part of the jacking frame 23. The two adjacent swing blocks 24 are rotatably connected through a synchronization rod 25; when the jacking cylinder 20 works, the crank 22 pushes the jacking drive shaft 21 to move, and through the cooperation of the hinge and under the synchronous coordinated restriction of the two swing blocks 24, the jacking frame 23 as a whole can achieve horizontal and stable lifting.

[0030] In addition, more specifically, the conveying module 3 includes a conveying frame 30, a conveying belt 31, a motor 32, a motor mounting plate 33, a transmission shaft 34, a sprocket 35 and a pulley 36;

The transmission shaft 34 is rotatably connected to the lower part of the conveyor frame 30, the pulley 36 is fixed on the transmission shaft 34, and the sprocket 35 is fixed on one end of the transmission shaft 34. The conveyor belt 31 is driven and wound around the conveyor frame 30 and the pulley 36. The conveyor belt 31 located at the top of the conveyor frame 30 is arranged in a horizontal form. The conveyor frame 30 can be raised from the interval between the rollers 10. The motor 32 is arranged on the bottom surface of the motor 32 mounting frame. The output end of the motor 32 is connected to the transmission shaft 34 through the sprocket 35. Therefore, when the motor 32 works, the conveyor belt 31 is driven through the transmission shaft 34, and the conveyor frame 30 lifts the material as a whole. In this way, whether it is scattered materials or long materials, they can be supported on the conveyor belt 31 as a whole and transported by the conveyor belt 31 along the second direction B. There will be no pushing deviation, so as to achieve stable feeding.

[0032] As mentioned above, further, a tensioning wheel 37 is rotatably provided on the conveying frame 30, and the position of the tensioning wheel 37 on the conveying frame 30 is adjustable. The upper part of the tensioning wheel 37 rolls with the lower side of the conveyor belt 31. By adjusting the position of the tensioning wheel 37, the tension of the conveyor belt 31 is adjusted to prevent the conveyor belt 31 from slipping.
