[0002] Packaging cartons are widely used for packaging of various products, especially for packaging of various medical devices, such as various syringes, etc. The paper blank material warehouse is used before the paper blanks of the packaging equipment are formed, and is used to store the paper blanks before the packaging cartons are formed, waiting for the subsequent equipment to take the materials. The working principle is: the paper blank material warehouse arranges the paper blanks neatly through limiting, and at the same time, it can realize the automatic forward replenishment of the paper blanks when they are continuously taken away, waiting for the subsequent material to be taken.

[0003] At present, most of the existing paper blank warehouses are single-group warehouses for storage and transportation. Materials can only be taken one by one, which affects the speed of forming and boxing. At the same time, the paper blank warehouse is generally connected to the equipment by bolts, and it is difficult to replace the tooling and fixtures for paper blanks of different specifications, which delays time when changing products.

DETAILED DESCRIPTION

[0024] like Figure 1-Figure 6 As shown, the utility model relates to a multi-station paper blank material warehouse that can be controlled individually, including a support frame 1, a mounting plate 2 is fixed on the support frame 1, and a plurality of L-shaped brackets 9 are evenly fixed on the mounting plate 2 by screws. This embodiment takes four brackets as an example, and a fixing plate 11 is connected to the top plate of each bracket 9 through a thumb-type locker 10. The fixing plate 11 and the top plate are plugged into each other through mutually matching bosses and grooves, and a paper blank conveying mechanism is fixed on the fixing plate 11 for placing and conveying paper blanks. A guide plate 7 is fixed on the support frame 1 above the mounting plate 2.

[0025] The support frame 1 includes a movable base 101, and walking wheels 105 are respectively provided at the four corners of the bottom surface of the base 101. Two vertical plates 103 are symmetrically fixed on the base 101 by screws. The two vertical plates 103 are trapezoidal and are connected to each other by three connecting rods 102 and three connecting strips 104 arranged up and down. The three connecting strips 104 are arranged in sequence up and down in parallel along the hypotenuse of the two vertical plates 103. The fixed plate 11 is fixed between the connecting strips 104 located in the middle and the lower end by screws, and the guide plate 7 is fixed between the connecting strips 104 located in the upper end and the middle by a spring plunger 14 and a thumb-type locker 13. Specifically, the lower end of the guide plate 7 is plugged with the connecting strip 104 located in the middle by two spring plungers 14, and the upper end of the guide plate 7 is locked with the connecting strip 104 located at the upper end by two thumb-type lockers 13. Two U-shaped blocks 8 are symmetrically fixed on the connecting strips 104 at the upper end and the middle part, respectively, so as to facilitate the connection between the spring plunger and the thumb-type locker.

[0026] The paper blank conveying mechanism comprises two support plates 17 fixed in parallel on both sides of the fixed plate 11 by screws, the support plates 17 are inverted V-shaped with unequal sides and the long sides are arranged horizontally, two synchronous belt mechanisms 3 are arranged between the two support plates 17 and connected with a support plate 16, the synchronous belts of the two synchronous belt mechanisms 3 are bypassed by rectangular grooves arranged on the support plate 16, and are used to support and convey the paper blanks 19 to be used; the two synchronous belt mechanisms 3 share a driving shaft 301, a driven shaft 302 and an intermediate shaft 303, wherein the intermediate shaft 303 is located at the corner of the support plate 17, and both ends of the driving shaft 301 are installed at the front end of the support plate 17 through bearings;

[0027] A swing arm 22 is installed in the middle of the driving shaft 301 through a one-way bearing, a connecting plate 24 is fixed between the bottoms of the two support plates 17, a cylinder 23 is hinged on the connecting plate 24, and the output end of the cylinder 23 is hinged to the lower end of the swing arm 22, which is used to drive the two synchronous belt mechanisms 3 to step and operate;

[0028] The outer sides of the two support plates 17 are fixedly connected with the limit plates 15 by two connecting columns 18 respectively. The spacing between the two limit plates 15 matches the length of the paper blank 19 to be conveyed, so as to realize the limitation during the conveyance of the paper blank. A support block 12 is placed between the two limit plates 15 on the two synchronous belt mechanisms 3 through the gap. The support block 12 follows the synchronous belt mechanisms 3 to step, so as to block the paper blank to be conveyed from the back.

[0029] A plurality of special-shaped guide holes 701 are evenly distributed on the guide plate 7, and the guide holes 701 correspond to the paper blank conveying mechanism one by one, and the front of the paper blank conveying mechanism is respectively passed through the corresponding guide holes 701; two guide bars 5 are respectively fixed on the left and right sides and the upper side of each guide hole 701 on the guide plate 7 through L-shaped brackets 4, which are used to guide the paper blank during conveying. A screw hole is respectively provided at the front end of each guide bar 5, and a ball screw 6 is screwed in to prevent the paper blank from falling.

[0030] Two photoelectric sensors 21 are fixed via sensor brackets 20 at the front side of the connecting strip 104 at the upper end in the middle of each guide hole 701 for detecting whether there is a shortage of paper on each paper blank conveying mechanism.

[0031] like Figure 7 As shown, a connecting component is fixed on the base 101 at the lower end of the support frame 1, and the connecting component includes a fixed block 25 and a connecting block 26. The fixed block 25 is fixed on the base 101, and the connecting block 26 is used to be fixed on the frame of the entire packaging equipment. A connecting shaft 28 is fixed on the fixed block 25, and one end of the connecting shaft 28 is provided with an annular groove and inserted into the connecting block 26. A spring plunger 27 is screwed into the connecting block 26, and the positioning column at the lower end of the spring plunger 27 is inserted into the annular groove for fixing and connecting the frame of the entire packaging equipment.

[0032] When in use, multiple groups of paper blanks are placed on the synchronous belt of each paper blank conveying mechanism, and the movable support block blocks the paper blanks to be conveyed from behind. The cylinder 23 is controlled to reciprocate. When the cylinder 23 is extended, the swing arm 22 idles on the driving shaft of the synchronous belt mechanism 3 through the one-way bearing. When the cylinder 23 is retracted, the swing arm 22 drives the driving shaft of the synchronous belt mechanism 3 to rotate through the one-way bearing, thereby driving the synchronous belt mechanism 3 to step and drive the paper blanks forward.

[0033] During operation, the paper blank conveying mechanism can be controlled to operate individually or simultaneously by controlling the cylinder 23 to act individually or simultaneously. When changing the specification, unlock the spring plunger 27 to pull the connecting shaft 28 out of the connecting block 26, so that the multi-station paper blank material library can be separated from the packaging equipment. Then, just release the thumb-type locker 10, 13 and the spring plunger 14 to remove and replace the paper blank conveying mechanism and the guide plate 7 of the corresponding paper blank, and then connect it to the packaging equipment through the connecting assembly.

[0034] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
