Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

as shown in the figure, the invention comprises a roller slideway conveying part, an output guide plate, a packaging mechanism, a clamping mechanism, a bracket and a universal wheel, wherein the roller slideway conveying part comprises a desktop clamping device B, a roller slideway I1, a roller slideway II 2 and a roller slideway III 3. The packaging mechanism comprises a sliding guide rail 42, a packaging mechanism bracket 32, a retractable rod 35, a swing rod 39, a roller 38, a cover closing device 40, a shaft 31, a blade box 33, a spring 34, a blade 36, a small roller 37, a sensor 41, a bolt 30, an O-shaped rubber ring 22 and a nut 29. The clamping mechanism comprises a clamping device 19, a conveyor belt 6, a polished rod 13, a ball screw 15, a ball bearing 16, a support 8, a stepping motor 17, a first gear 11, a second gear 12, a support 40, a sliding barrel 20, a control electric box 14 and a support 10. The packaging mechanism support 32, the support 10, the roller slideway three 3, the output guide plate 7, the sensor 24 and the universal wheel 5 are arranged on the support 4. The first roller slideway 1 is connected with the second roller slideway 2 through a fixing stud 25. The second roller slideway 2 is connected with the third roller slideway 3 through a fixing stud 26. The roller slideway three 3 is connected with the output guide plate 7 through a bolt 18. The bracket 8 and the bracket 9 are arranged on a clamping device 19. In the above-mentioned scheme, packing personnel only need pack the goods into the carton and then put the carton on the inclined plane by the inclined plane gliding to the encapsulation part just can, need not to carry out more other operations. The automation degree of the whole process is improved, the efficiency is improved, and the workload of workers is greatly reduced.

The desktop fastener B comprises a slide block 28, a guide groove 27, a bolt 21 and a nut 23, and the tightness of the bolt and the nut can be adjusted to clamp the desktop

The packaging part in the embodiment of the invention comprises a sliding guide rail 42, a packaging mechanism bracket 32 rigidly connected with the sliding guide rail 42, a retractable rod 35 connected with a swing rod 39 through a pin, the swing rod 39 connected with the packaging mechanism bracket 32 through a pin, a roller 38, a cover closing device 40, a shaft 31, a blade box 33, a spring 34, a blade 36, a small roller 37, a sensor 41, a bolt 30, an O-shaped rubber ring 22 and a nut 29. Because the middle of the retractable rod is provided with a moving distance, the moving stroke of the whole device is partially shortened, the whole packaging time is shortened, and the efficiency is improved. The whole blade box presses the rear half part of the traditional packaging part and the adhesive tape cutting blade are combined together, the swing of the swing rod is changed into vertical movement, and the size of the whole mechanism and the movement distance of a package are reduced.

The clamping mechanism in the embodiment of the invention comprises a clamping device 19, a conveyor belt 6 fixed on the clamping device 19, a polished rod 13, a ball screw 15, a ball bearing 16, a bracket 8, a stepping motor 17 connected with the bracket through bolts, a first gear 11, a second gear 12, a bracket 9, a sliding cylinder 20, a control electric box 14 and a bracket 10. And the plc controls the clamping device to clamp according to the result measured by the sensor during working, so that the cartons with different widths are packaged.

When the wrapping device is used, the fixing studs 25 between the first roller slideway 1 and the second roller slideway 2 and the fixing studs 26 between the second roller slideway 2 and the third roller slideway 3 can be loosened, so that the first roller slideway 1 and the second roller slideway 2 can rotate up and down, and the rotation angle can reach 180 degrees. When folding is desired. The roller slideway 2 can be rotated upwards to be in a 90-degree state with the roller slideway 3, and the roller slideway 1 is rotated upwards to be in a parallel state with the roller slideway 3. At this time, the fixing stud 25 is screwed and the fixing stud 26 is fixed, thereby achieving the purpose of folding. Fixing studs 25 and 26 between the first roller slideway 1, the third roller slideway 3 and the second roller slideway 2 are connected by equal-length studs. Its advantages are easy replacement, easy folding and high pretightening force. When the output guide plate 7 is folded, the output guide plate 7 can rotate up and down by unscrewing the bolts 18 according to the same principle as the roller slideway. And when the output guide plate 7 is rotated upwards to form an angle of 90 degrees with the roller slideway three 3, the bolt 18 is screwed down, and finally, the support connected with the universal wheel 5 is rotated upwards by 90 degrees, so that the whole folding process is finished.

When the automatic express packaging device is used, firstly, the roller slideway I1 is fixed on a desktop through the desktop clamping device B, then a carton filled with goods is pushed into the roller slideway with the inclination angle of 45 degrees, and the carton slowly slides to the bottom end of the roller slideway II 2 under the action of gravity. At this time, the sensors 24 and 41 sense the approach of the carton and measure the height and width of the carton, and the width of the clamping portion and the height of the enclosing portion are adjusted to match the introduced carton. The conveyor 6 in the gripper 19 is then activated and operates in conjunction with the roller slide three 3 to bring the cartons into the enclosure. During the carrying process, the position of the carton is aligned by the front end inclined plane of the clamping device 19, the two hinges of the carton are bent and pressed by the cover closing device 40, then the front end of the carton touches the roller 38 with the adhesive tape hung at the front end of the packaging part to enable the adhesive tape to be attached to one end of the carton, and then the roller 38 is lifted upwards along with the advance of the carton, and simultaneously the retractable rod 35 drives the blade 36 to retract into the blade box 33 and enables the spring 34 to be in a stretching state. When the carton is to be transferred out of the enclosure, the roller 38 is first separated from the carton and the blade 36 is slid downwardly under the tension of its internal spring and against the carton by the small roller 37. As the carton is pushed further out, the small roller 27 and carton separating blade 36 fall completely to cut and compact the tape. Finally the carton is pushed further out by the conveyor 6 through the output guide 7 out of the packaging machine.
