By installing the limiting plate 10 on the fixed rod 9, the limiting plate 10 can adjust the moving distance of the movable plate 5, so that the conveying distance of the conveyor belt 2 can be conveniently adjusted as needed.

[0021] In this embodiment, the top of the fixing rod 9 is provided with grooves at equal intervals, the bottom end of the limiting plate 10 is provided with an arc-shaped groove, the top of the inner wall of the arc-shaped groove is fixedly provided with a protrusion, the fixing rod 9 is snap-fitted and installed inside the arc-shaped groove, the protrusion is installed inside the groove, and the limiting plate 10 is arranged on one side of the movable plate 5. The limiting plate 10 can be limited by the action of the protrusion and the groove, thereby improving the stability of the limiting plate 10.

[0022] In this embodiment, the shape of the movable plate 5 is "L"-shaped, and a slider 15 is fixedly provided on one side of the top of the movable plate 5. A limiting groove is provided on the front wall of the frame 1 below the fixed rod 9, and the slider 15 is slidably installed inside the limiting groove. A buffer plate 3 is obliquely provided at one end of the frame 1. The movable plate 5 can be limited by the limiting groove and the slider 15, thereby improving the stability of the movable plate 5 and facilitating the subsequent lateral adjustment of the movable plate 5.

[0023] In this embodiment, a rack 11 is fixedly provided on the top of the bottom end of the movable plate 5, a cylinder 6 is fixedly installed on one side of the movable plate 5 corresponding to the frame 1, the output rod of the cylinder 6 is fixedly connected to the movable plate 5, the transmission mechanism 4 includes a ratchet 13, the ratchet 13 is fixedly installed on one end of the rotating roller on the left, a toothed ring 12 is rotatably provided on the outer side of the ratchet 13, a pawl 14 is movably installed on the inner wall of the toothed ring 12 through a torsion spring rotating shaft, one end of the pawl 14 is clamped in the inside of the card slot on the ratchet 13, and the meshing device of the rack 11 It is placed at the bottom of the toothed ring 12. Through the action of the ratchet 13 and the pawl 14, when the movable plate 5 drives the toothed ring 12 to rotate clockwise through the rack 11, the toothed ring 12 drives the rotating roller to rotate through the action of the pawl 14 and the ratchet 13, which is convenient for driving the corrugated cardboard to the right side through the conveyor belt 2. When the movable plate 5 moves in the opposite direction, it is driven to rotate in the opposite direction through the meshing action of the rack 11 and the toothed ring 12. The pawl 14 rotates under the squeezing of the ratchet 13 to avoid driving the ratchet 13 to rotate, thereby stopping the conveyor belt 2 from conveying, which is convenient for processing the corrugated cardboard.

[0024] When using the pneumatic fixed-distance conveying device, according to the required distance for moving the corrugated cardboard at one time, the limit plate 10 is installed on the top of the fixed rod 9 through the arc groove, and the protrusion is stuck in the corresponding groove. The corrugated cardboard to be conveyed is placed on the top of the conveyor belt 2 from the left end of the frame 1. The cylinder 6 is connected to the air supply equipment through the air pipe. When the cylinder 6 is started, its conveying rod pushes the movable plate 5 to move to the left, and the movable plate 5 slides on the fixed rod 9 through the sliding hole, and at the same time drives the slider 15 to slide inside the limiting groove. The stability of the movable plate 5 is improved by the fixed rod 9, the slider 15 and the limiting groove. The movable plate 5 drives the rack 11 to move to the left, and the gear ring 12 is driven to rotate clockwise through the meshing action of the rack 11 and the gear ring 12. At the same time, the gear ring 12 drives the ratchet 14, and the ratchet 14 drives the ratchet 13 to rotate clockwise through the interaction with the card slot, which is convenient for passage. The conveyor belt 2 is driven by the ratchet 13 and the rotating roller to move the corrugated cardboard at a fixed distance through the conveyor belt 2. When the movable plate 5 moves in the opposite direction driven by the cylinder 6, the movable plate 5 drives the gear ring 12 and the pawl 14 to rotate in the opposite direction through the action of the rack 11 and the gear ring 12, and the pawl 14 rotates through the torsion spring shaft under the extrusion of the ratchet 13, so it cannot drive the ratchet 13 to rotate in the opposite direction. At this time, the conveyor belt 2 is in a stopped state, which is convenient for gluing the corrugated cardboard and the facial paper. Through the reciprocating motion of the cylinder 6, the rotating roller can be driven to rotate intermittently through the movable plate 5, the rack 11, the gear ring 12, the pawl 14, and the ratchet 13, which is convenient for intermittent operation and suspension of the conveyor belt 2, avoiding damage and reduced life caused by the use of ordinary motors, and has high practicality; the buffer plate 3 is arranged on the right side of the conveyor belt 2, and the buffer plate 3 is convenient for the downward discharge of the processed corrugated cardboard.
