[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] Reference Figures 1 to 4 The conveying and dispensing device of the utility model is implemented as follows:

[0030] A material conveying and discharging device comprises: a base frame 100 and a material discharging mechanism 200.

[0031] The base frame 100 has a material transfer plane for supporting or transferring foreign materials.

[0032] The material shifting mechanism 200 includes: a material shifting member 210, a transmission member 220 and a material shifting driving unit.

[0033] The transmission member 220 is arranged at the lower side of the material-digging conveying plane. The transmission member 220 includes: a transverse connecting rod 221 and two crank rods 222. The transverse connecting rod 221 and the two crank rods 222 form a parallelogram connecting rod mechanism with the base frame 100. The material-digging member 210 is connected to the transverse connecting rod 221, and the material-digging driving unit is used to drive the crank rod 222 to rotate.

[0034] In actual use, the material-dispensing driving unit drives one of the crank rods 222 to rotate, so that the transverse connecting rod 221 can translate relative to the base frame 100. The material-dispensing member 210 can extend from bottom to top to the upper side of the material-dispensing conveying plane as the transverse connecting rod 221 moves, pushing the material on the material-dispensing conveying plane forward, and finally retracting to the lower side of the material-dispensing conveying plane to realize the material-dispensing conveying. The material-dispensing member 210 of the translational material-dispensing has little effect on the subsequent docking of the material, and is driven by a parallelogram linkage mechanism, with a simple structure and high repeatability.

[0035] In this embodiment, the two crank rods 222 are arranged front and back. The two ends of the crank rod 222 have a hinge end 2221 and a swing end 2222. The hinge ends 2221 of the two crank rods 222 are both rotatably hinged to the base frame 100, and the swing ends 2222 of the two crank rods 222 are respectively rotatably hinged to the front and rear ends of the transverse connecting rod 221. The two crank rods 222 are parallel to each other, and the spacing between the two hinge ends 2221 is consistent with the spacing between the front and rear ends of the transverse connecting rod 221. When the crank rod 222 rotates around the hinge end 2221, the transverse connecting rod 221 can always be parallel to the front and rear direction and move parallel to the base frame 100.

[0036] In order to prevent the eccentric moment of inertia of the crank rod 222 from being too large and causing large fluctuations in the rotation speed, a counterweight portion 2223 is provided at the hinge end 2221 of the crank rod 222. The counterweight portion 2223 and the swing end 2222 are respectively arranged at two ends of the hinge end 2221 on opposite sides in the radial direction. The counterweight portion 2223 is in the shape of a fan-shaped disk. The counterweight portion 2223 can form a flywheel structure. When the crank rod 222 rotates around the hinge end 2221, the counterweight portion 2223 and the swing end 2222 arranged at both ends of the hinge end 2221 can balance each other, thereby preventing the crank rod 222 from causing vibration when rotating.

[0037] Referring to the accompanying drawings, in the present embodiment, the number of the material-diverting member 210 is one. The bottom of the material-diverting member 210 is connected to the upper end of the transverse connecting rod 221. In some other embodiments, the number of the material-diverting member 210 can be multiple. Multiple material-diverting members 210 are arranged at intervals along the front-to-back direction on the upper side of the transverse connecting rod 221. The distance between two adjacent material-diverting members 210 does not exceed the distance between the hinge end 2221 and the swing end 2222. The multiple material-diverting members 210 that act synchronously divert materials in sequence to achieve multi-stage material diverting and conveying.

[0038] The transverse connecting rod 221 is in the shape of a long strip and extends in the front-to-back direction. In order to facilitate the adjustment of the position of the material-diverting and conveying stroke of the material-diverting member 210, it is preferred that the relative position of the material-diverting member 210 and the transverse connecting rod 221 can be adjusted front-to-back. In the present embodiment, the transverse connecting rod 221 has a strip hole extending front-to-back. The lower end of the material-diverting member 210 has a connecting screw that penetrates the strip hole, and the material-diverting member 210 and the transverse connecting rod 221 are locked and fixedly connected by the connecting screw. When the connecting screw is loosened, the material-diverting member 210 can be adjusted front-to-back relative to the transverse connecting rod 221, so that the material-diverting path of the material-diverting member 210 can be adjusted front-to-back, and the material-diverting and conveying of materials of different sizes and specifications can be realized.

[0039] In this embodiment, the material-digging member 210 is in the shape of a right-angled triangular plate, and one end of the material-digging member 210 along the conveying direction has a material-digging portion 211 extending up and down. The material-digging portion 211 is perpendicular to the bottom end of the material-digging member 210. The triangular plate-shaped material-digging member 210 has high strength, and is narrow at the top and wide at the bottom, so that it can be easily inserted between two adjacent materials, thereby realizing material-digging and conveying of materials one by one.

[0040] In this embodiment, the conveying and material-digging device further comprises a conveying mechanism 300. The conveying mechanism 300 comprises two conveying members. The two conveying members are arranged symmetrically. The upper ends of the two conveying members form the material-digging conveying plane, and there is a material-digging gap between the two conveying members, and the material-digging member 210 is aligned with the material-digging gap up and down.

[0041] In actual use, the two conveying components can respectively support the left and right sides of the bottom of the packaging material. Under the action of the transmission component 220, the material-discharging member 210 extends upward from the material-discharging gap to the upper side of the material-discharging conveying plane for material-discharging and conveying.

[0042] In this embodiment, the conveying member is a belt conveyor. The conveying member includes: a conveying drive unit 310, a conveying pulley 320 and a conveying belt 330. At least two of the conveying pulleys 320 are arranged front and back. The conveying pulleys 320 are rotatably connected to the base frame 100. The conveying belt 330 is driven and wound around the conveying pulleys 320, and the upper end of the conveying belt 330 extends forward and backward, so that the upper end belt surface of the conveying belt 330 can form the material-selecting conveying plane. The conveying drive unit 310 is used to drive one of the conveying pulleys 320 to rotate.

[0043] Considering the convenience of controlling the speed and accuracy of conveying and material selection, the conveying drive unit 310 and the material selection drive unit in this embodiment both adopt servo motors. In other embodiments, the conveying drive unit 310 and the material selection drive unit can be rotation drive elements such as stepping motors or pneumatic motors.

[0044] In some other embodiments, the conveying drive unit 310 and the material removal drive unit are the same drive motor, and one of the crank rods 222 and one of the drive pulleys can be synchronously connected through various transmission methods such as belt drive, chain drive, gear drive or worm gear drive.

[0045] In order to avoid affecting the material conveying, the width of the material-diverting gap is small, so the material-diverting member 210 is small in thickness. In this embodiment, two material guide plates 110 are vertically arranged on the left and right sides of the upper end of the base frame 100. The two material guide plates 110 are arranged opposite to each other on the left and right sides. The two material guide plates 110 can limit and guide the left and right sides of the material respectively, forming a conveying channel extending forward and backward, so as to avoid the material from swinging or even turning over during the material-diverting conveying process.

[0046] To accommodate packaging materials of different sizes, the guide plate 110 is adjustably connected to the base frame 100. In this embodiment, the base frame 100 is adjustable left and right with a connecting rod 120, and the end of the connecting rod 120 is adjustably connected to the guide plate 110 front and back.

[0047] Specifically, the base frame 100 has a connecting hole extending from left to right. The connecting rod 120 is inserted into the connecting hole. The base frame 100 is threadedly provided with a tightening screw that abuts against the connecting rod 120. The connecting rod 120 is locked and fixed in the connecting hole by the tightening screw.

[0048] The connecting rods 120 are arranged in pairs on the left and right sides of the base frame 100. The ends of the connecting rods 120 facing each other are respectively connected to the two guide plates 110 in a front-to-back adjustable manner. The two guide plates 110 have connecting grooves extending front-to-back on the opposite sides, and the ends of the connecting rods 120 are embedded in the connecting grooves.
