The back of the pushing plate 4 is connected to the piston rod 5 of the cylinder. The telescopic movement of the piston rod 5 of the cylinder drives the pushing plate 4 to move horizontally back and forth along the placement table 2, pushing the medicine collection package on the conveyor belt 1 to the grasping station of the placement table 2, waiting for the grasping device to grasp and pack. On the right side of the pushing plate 4, a fixed plate 6 is longitudinally provided. On the left side of the pushing plate 4, a flow bar 7 is provided. The front end of the flow bar 7 is inclined towards the fixed plate 6, and the inclination angle is 2 - 5°. Moreover, the distance between the front end of the flow bar 7 and the fixed plate 6 is equivalent to the width of the medicine collection package.

[0023] By respectively arranging the flow bar 7, the fixed plate 6 and the baffle 3 on the left and right sides and the front end of the placement table 2, and controlling the telescopic movement of the piston rod 5 of the cylinder to use the pushing plate 4 to push the medicine collection package to be packed onto the placement table 2, with the right end of the medicine collection package flush with the fixed plate 6. Among them, the flow bar 7 is inclined, realizing the stable stacking and caching of the medicine collection package, being reliable and durable, and solving the problems that the current use of the brush is deformed, resulting in uneven stacking, jamming of medicine, and the brush will shed hair, causing quality hazards.

[0024] Specifically, the above-mentioned flow bar 7 includes a mounting seat 701 and a number of rollers 702. The mounting seat 701 is in a U shape. The top plate of the mounting seat 701 is hinged to the side plate of the mounting seat 701. Along the length direction, a number of groups of round holes 7011 and grooves 7012 are evenly spaced on the top plate and the bottom plate of the mounting seat 701. The rotating shaft 703 is rotatably connected to the roller 702 and both ends penetrate through the roller 702. The bottom end of the rotating shaft 703 is embedded in the groove 7012, and the top end extends out of the top plate of the mounting seat 701 through the round hole 7011 and is fastened with a nut. The hinged connection between the top plate of the mounting seat 701 and the side plate of the mounting seat 701 is convenient for the installation of the roller 702; the detachable fixed connection between the roller 702 and the mounting seat 701 is convenient for maintenance and replacement of the roller 702, ensuring the quality of the stacking and caching of the medicine collection package. At the same time, the appropriate roller 702 can be selected according to the variety of the medicine collection package.

[0025] In order to further improve the versatility and practicality of the positioning and pushing mechanism of the packing machine, the side plate of the above-mentioned mounting seat 701 is fixedly connected to the L-shaped mounting plate 8 by bolts. Two strip-shaped mounting holes 201 are horizontally opened on the placement table 2. The bottom plate of the L-shaped mounting plate 8 is fixed on the placement table 2 by bolts through the strip-shaped mounting holes 201, realizing the adjustable inclination angle of the flow bar 7.

The front end of the smooth strip 7 is tilted toward the fixed plate 6, and the tilt angle is 2-5°. The distance between the front end of the smooth strip 7 and the fixed plate 6 is equivalent to the width of the medicine collection package. During production, the cylinder piston rod 5 is extended and retracted to drive the push plate 4 to move horizontally forward and backward along the placement table 2, and push the medicine collection package on the conveyor belt 1 to the grabbing station of the placement table 2, waiting for the grabbing device to grab and pack. Since the smooth strip 7, fixed plate 6 and baffle 3 are respectively set on the left and right sides and the front end of the placement table 2, the right end of the medicine collection package is flush with the fixed plate 6, and the smooth strip 7 is tilted to achieve stable stacking and caching of the medicine collection package.
