A drive plate is slidably arranged in the groove of the sliding groove plate, and an upward-facing rack a is fixed at the center of the drive plate.

[0007] Two sliding plates are fixed with support blocks on their outer sides, and the top of the support blocks is provided with a top plate corresponding to the bottom sliding plate. A downward-facing rack b is fixed on the top plate.

[0008] Gears a and b are respectively provided between rack a and rack b. Gears a and b mesh with the upper and lower racks a and rack b, and the two are rotatably connected by a connecting rod a on the side. A fixed shaft is provided at the center of the connecting rod a.

[0009] A servo motor is installed behind the slide plate. A drive handle is fixedly connected to the output shaft of the servo motor. The drive handle and the fixed shaft at the center of the connecting rod a are rotatably connected by a connecting rod b.

[0010] Furthermore, neither gear a nor gear b will disengage from rack a and rack b when rotating synchronously. Rack a will move back and forth as gears a and b rotate, and during the displacement process, the length of the drive plate that extends beyond the slide plate is less than one-third of its total length.

[0011] Furthermore, the drive plate is a horizontal L-shaped plate, with its corner located at the front end of the slide plate.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] As shown in Figures 1 to 6, this utility model includes two sliding plates 2 fixed on the base plate 1 and standing opposite each other, which serve as the displacement medium of the pushing assembly. A driving plate 3 is slidably arranged in the sliding groove of the sliding plate 2, and an upward-facing rack a4 is fixed at the center of the driving plate 3.

[0033] Support blocks 101 are fixed to the outer sides of the two slide plates 2, and a top plate 6 corresponding to the bottom slide plate 2 is provided on the top of the support block 101. A downward rack b7 is fixed on the top plate 6. Gears a5 and b501 are respectively provided between the racks a4 and b7. Gears a5 and b501 mesh with the upper and lower racks a4 and b7, and the two are rotatably connected by a connecting rod a8 on the side. A fixed shaft is provided at the center of the connecting rod a8.

[0034] A servo motor 11 is provided behind the slide plate 2. A drive handle 10 is fixedly connected to the output shaft of the servo motor 11. The drive handle 10 and the fixed shaft at the center of the connecting rod a8 are rotatably connected by a connecting rod b9 to form a crank-connecting rod mechanism, which serves as a pushing component for pushing materials.

[0035] When gears a5 and b501 rotate synchronously, they will not disengage from racks a4 and b7. Rack a4 will move back and forth as gears a5 and b501 rotate, and during the displacement, the length of the drive plate 3 that extends beyond the slide plate 2 is less than one-third of its total length.

[0036] The drive plate 3 is a horizontal L-shaped plate, with its corner located at the front end of the slide plate 2. A pusher plate 305 is fixed at the front end of the drive plate 3. The pusher plate 305 is provided with two U-shaped limiting grooves 301 and a through groove a3011 at the bottom of the groove.

[0037] Each limiting groove 301 is equipped with a push block 302, and the push block 302 is provided with a through groove b3021 that runs vertically through the groove and corresponds to the position of the through groove a3011.

[0038] The push block 302 can be adjusted in the front and back position in the limiting groove 301, and can also be fixed by bolts through the through groove a3011 and the through groove b3021.

[0039] Each pusher 302 has a rubber block 303 fixedly connected to its front end.

[0040] A distance sensor 12 is installed on the front end face of the drive board 3 to detect the distance of the material. The distance sensor 12 is higher than the pusher plate 305.

[0041] The drive plate 3 has several slots 304 on both sides of the rack a4. The slots 304 are perpendicular to the rack a4. Each slot 304 is equipped with a locking block 13 that is fixedly connected to the rack a4 for further fastening the rack a4.

[0042] Referring to Figure 6, this utility model is installed on the side of the conveyor track directly opposite the pharmaceutical materials and packaging boxes. The conveyor belt and the arrangement of materials are existing technologies and will not be described in detail.

[0043] The principle of this utility model is as follows:

[0044] (1) The servo motor 11 drives the drive handle 10 to rotate, and then the connecting rod b9 causes the connecting rod a8 to reciprocate back and forth. The stroke of the connecting rod a8 is the rotation diameter of the (protruding pin) on the drive handle 10.

[0045] Since gears a5 and b501 are also being driven to move and are rotating during the movement, the rack a4 that it works with moves not only the distance of the rotation diameter of the drive handle 10 (protruding pin) but also the distance of the gear rolling. This results in the phenomenon that the overall movement distance of the drive plate 3 is magnified, thus solving the problem of the drive mechanism reciprocating in a narrow space.

[0046] (2) The distance sensor 12 is connected to the host computer (e.g., PLC) to detect the distance between itself and the pharmaceutical material at all times. After the pusher plate 305 pushes the packaging box, it is subjected to reciprocating motion and then withdraws. The distance sensor 12 ensures that the material is pushed into place and prevents the phenomenon of jamming (when the material is jammed, the distance parameter of the distance sensor 12 changes inconsistently with the normal state). At the same time, the two front pushers 302 can also adjust the final push position of the pusher.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
