Description

Technical Field

[0001] The utility model relates to the technical field of medicine packaging, in particular to a feeding structure of a cartoning machine. Background Art

[0002] Capsule drugs are usually packed in boxes, and after the finished products are produced, they need to be packaged in boxes. In the prior art, drug cartoning machines generally have two conveyor lines, one for conveying drugs and the other for conveying boxes, and then cooperate with a pushing mechanism to allow the drugs to enter the corresponding boxes, thereby packaging the drugs. However, in actual applications, since the conveyor belt is fixed with a limit plate for limiting the boxes, the distance between adjacent limit plates is fixed, and the widths of various medicine boxes are different, so that the conveyor belt can only convey boxes of certain specific specifications, which is limited in actual application, not conducive to expanding the scope of application, and inconvenient to use. To this end, we propose a feeding structure for a cartoning machine. Utility Model Content

In practical applications, the limiting groove 5 of a specific model and the chain 2 can be directly regarded as a whole, and then the chain 2 suitable for different models of packaging boxes can be replaced by replacing the chain 2. Compared with the method of directly replacing the limiting groove 5, it is more labor-saving for a conveying mechanism with a longer conveying distance;

[0023] Specifically, by setting a chain plate 4, a sprocket, a chain 2, a positioning rod 6, a nut 7 and an assembly plate 3, the positioning rod 6 fixed at the bottom of the limiting groove 5 is passed through the chain plate, and then cooperated with the nut 7 to lock the positioning rod 6 and the chain plate 4, and then the limiting groove 5 and the chain plate 4 adapted to the packaging box are installed. Compared with the prior art, in actual applications, according to the width of the packaging box, the nut 7 can be removed to disengage the positioning rod 6 from the chain plate 4, so as to replace the limiting groove 5 adapted to the packaging box of different widths, thereby expanding the scope of application and improving the flexibility of use.

[0024] A conveyor belt 23 is provided above the conveying mechanism and moves in the opposite direction thereto, and a material pushing mechanism is provided between the conveyor belt 23 and the conveying mechanism; Figure 1As shown, the conveying mechanism moves from left to right, and the conveyor belt 23 moves from right to left. The conveyor belt 23 is used to convey the packaging box to the pushing mechanism, and then the pushing mechanism is used to send the packaging box into the limiting groove 5. In fact, the right end of the conveying mechanism continues to extend, and the length of the conveying mechanism is shortened due to the layout limitation. At the right end of the conveying mechanism, a drug conveying mechanism and a drug loading mechanism are provided, thereby completing the drug packaging;

[0025] Further, the push mechanism includes a frame 9 arranged on both sides of the base 1, and the two ends of the conveyor belt 23 are respectively connected to the frame 9 and the base 1 through support arms 24, and the support arms 24 are assembled with the frame 9 and the base 1 through fasteners. A fixed plate 10 is installed between the frames 9, and a support plate 16 is fixed to the side of the fixed plate 10 close to the conveyor belt 23, and a push plate 17 is movably provided above the support plate 16; a plurality of through grooves are evenly arranged on the support plate 16, and a sliding block that fits with the through grooves is fixed at the bottom of the push plate 17, so as to achieve the purpose of concave-convex matching between the support plate 16 and the push plate 17, thereby providing effective support for the push plate 17;

[0027] Furthermore, a baffle 18 is fixed on the frame 9 and abuts against the push plate 17. The baffle 18 is used to prevent the packaging box from falling into the gap between the frame and the support plate 16. A guide rod 22 that is slidably arranged on the guide arm 19 is fixed in the baffle 18. A guide groove 21 that cooperates with the guide arm 19 is opened on the baffle 18. The guide arm 19, the guide rod 22 and the guide groove 21 are used to guide the moving direction of the push plate 17 to prevent deviation.

[0028] A positioning plate 11 is movably provided on the top of the fixed plate 10;

[0029] Furthermore, a screw 13 is fixed at the bottom of the positioning plate 11, and a moving groove 14 matching the screw 13 is opened on the fixing plate 10, and the screw 13 is locked with the fixing plate 10 through a nut 15; by moving the screw 13 left and right along the moving groove 14, the positioning plate 11 is driven to move left and right, so that enough space is left at the left end of the positioning plate 11 for packaging boxes of different lengths to pass through, which is convenient for adjustment and improves the flexibility of use;

[0030] Furthermore, a docking plate 12 is provided on one side of the positioning plate 11, which is in contact with the surface of the fixing plate 10; the docking plate 12 is used to further limit the positioning plate 11 to prevent an angle from being formed between the positioning plate 11 and the fixing plate 10;

[0031] Specifically, by setting up a conveyor belt 23 and a pushing mechanism, the conveyor belt 23 is used to convey the packaging box forward, so that the packaging box falls on the support plate 16, and then by moving the pushing plate 17 forward, the packaging box is forced to move forward and then falls on the limiting groove 5, thereby completing the feeding of the packaging box. Compared with the prior art, the positioning plate 11 is moved left and right to limit the packaging box on the support plate 16, so that the falling point of the packaging box is located, thereby improving the accuracy of feeding.
