[0038] The multifunctional base 30 is provided at the bottom of the machine 10. One side of the base is provided with a plurality of negative pressure connection sleeves 40 corresponding to the blanking seats 11. The side wall of the negative pressure connection sleeve 40 is provided with a negative pressure input port 41 connected to the inside thereof.

[0039] The suction hose 20 is passed through the upper and lower parts of the machine platform 10 , with one end thereof communicating with the suction port 12 , and the end of the negative pressure connecting sleeve 40 is connected to the other end of the suction hose 20 .

[0040] The waste collection container 50 is provided on a side of the multifunctional base 30 away from the negative pressure connection sleeve 40 and has an accommodating space (not shown) in communication with the negative pressure connection sleeve 40;

[0041] The external negative pressure generating device has a negative pressure output end and is connected to the negative pressure input port 41, and is used to generate negative pressure in the suction hose 20 through the negative pressure connecting sleeve 40. In this embodiment, the external negative pressure generating device is a micro vacuum pump or a negative pressure fan.

[0042] Specifically, in this embodiment, the unloading seat 11 is generally arranged on the edge of the edge sealing mechanism 14 and the edge trimming mechanism 15 on the machine 10. The edge sealing mechanism 14 is used to perform hot-melt edge sealing and waste edge cutting on the four corners of the packaging box, and the edge trimming mechanism 15 is used to perform hot-melt edge sealing and waste edge cutting on the opening side of the packaging box after the packaging box is pushed into the laminating bag. The waste edges generated at the two positions are absorbed by the negative pressure generated by the suction port 12 of the unloading seat 11, so that they fall smoothly into the waste collection container 50.

[0043] Preferably, Figure 1 、 2 As shown in FIG. 3 , a connector 13 communicating with the suction port 12 is provided on the side of the discharge seat 11 away from the suction port 12 , thereby facilitating the plug-in connection between the suction hose 20 and the discharge seat 11 .

[0044] Preferably, Figure 2 、 3As shown, the suction hose 20 is a retractable plastic bellows, and both ends of the plastic bellows are respectively formed with plug interfaces for connection (not marked in the figure). Thus, through the plastic bellows, a flexible connection between the interface and the negative pressure connecting sleeve 40 can be achieved, and the action of the edge sealing mechanism 14 can be coordinated to achieve convenient absorption of waste cut from the edge sealing structure.

[0045] Preferably, Figure 4 、 5 As shown, the multifunctional base 30 includes a main frame 31, which is enclosed by a square bottom plate 32 and four vertically arranged side plates 33 to form a square box body with an open side. The bottoms of the four negative pressure connecting sleeves 40 are fixed on the bottom plate 32. The negative pressure connecting sleeve 40 includes a barrel 42 and a fixed end 43. A transmission channel 44 is formed inside the barrel 42 and the fixed end 43. The fixed end 43 penetrates from one side of the bottom plate 32 to the other side and is locked and fixed by an annular clamping member 45. The negative pressure input port 41 is provided on the side wall of the barrel 42, and the end of the barrel 42 away from the fixed end 43 forms a plug-in portion 46 connected to the end of the suction hose 20. In this embodiment, the clamping member 45 is an annular member with a notch, and the notch position is tightened by a locking bolt to achieve locking and fixation of the fixed end 43, thereby achieving convenient fixation of the negative pressure connecting sleeve 40 to the bottom plate 32.

[0046] Preferably, Figure 4 、 5 As shown, the four side panels 33 extend vertically toward the squares away from each other on one side away from the bottom plate 32 to form overlapping edges 34. The four overlapping edges 34 are provided with columnar hooks 35 on the side away from the opening of the main frame 31. The ends of the columnar hooks 35 gradually narrow to form sharp ends (not marked in the figure). Therefore, the waste collection container 50 can be easily fixed and replaced through the overlapping edges 34 and the columnar hooks 35.

[0047] Preferably, Figure 4 、 5 As shown, an L-shaped connecting plate 36 is provided at the bottom of the bottom plate 32 away from the side plate 33, and the main frame 31 is vertically locked and fixed to the bottom of the machine 10 through the connecting plate 36. In this embodiment, the main frame 31 is vertically fixed to the bottom of the machine 10, and its opening square is horizontally facing relative to the bottom surface of the machine 10, thereby facilitating the fixing of the main frame 31 to the bottom of the machine 10.

[0048] Preferably, Figure 3 As shown, the waste collection container 50 is a flexible bag, which is a canvas bag or a plastic bag. In this embodiment, the flexible bag is a canvas bag, so that it is convenient to connect with the columnar hook 35 on the main frame 31 through the flexible bag, and it is convenient to disassemble and replace, so as to facilitate the centralized and unified treatment of the collected waste.

[0049] Preferably, Figure 2 , 3 As shown in FIG. 6, a guide plate 60 is provided at the upper end of the machine table 10 and on one side of the blanking seat 11. A guide port 16 communicating with its interior is provided through the upper end surface of the machine table 10. A guide channel 61 with openings on both sides and communicating with the guide port 16 is provided inside the guide plate 60. In this embodiment, the cross-section of the guide plate 60 is in a U shape, and its bottom extends horizontally outward to form a connecting edge 62. A connecting hole 63 is provided through the connecting edge 62. A locking hole (not marked in the figure) opposite to the position of the connecting hole 63 is provided on the upper end surface of the machine table 10 and around the guide port 16. Thus, through the guide plate 60, the suction hose 20 can smoothly transition to the inside of the machine table 10 through the guide channel 61 inside it, providing certain constraints to prevent the suction hose 20 from hitting other positions of the equipment during the movement following the edge sealing mechanism 14.

[0050] In addition, as Figure 7 shown, another auxiliary waste collection box 70 is provided at the position of the trimming mechanism 15. A waste collection channel 71 that is vertically connected is formed inside the auxiliary waste collection box 70. A linear waste collection port 72 is formed on its upper side, and a tubular insertion end 73 that is convenient for docking with the suction hose 20 is formed at the lower end. The insertion end 73, the waste collection channel 71, and the waste collection port 72 are sequentially connected. Since the opening of the packaging box wrapping film is closed by linear hot melt cutting, the linear waste collection port 72 on the upper side is convenient for cooperating with the above-mentioned hot melt cutting process. Moreover, the upper side of the auxiliary waste collection box 70 can be narrowed to form a fitting surface 74, and locking edges 75 for locking are provided on both sides of the fitting surface 74, so that it can be directly installed and fixed at the hot melt cutting position of the packaging box wrapping film, and thus the waste edges can be directly sucked away after hot melt cutting.

[0051] The working process and beneficial effects of the present utility model are as follows:

[0052] First, the overall film wrapping machine wraps and seals the packaging box, and performs hot melt edge trimming at the positions of the edge sealing mechanism 14 and the trimming mechanism 15. The cut waste is sucked in along the suction port 12 of the blanking seat 11 under the negative pressure suction generated by an external negative pressure generating device, and finally enters the waste collection container 50 through the transmission of the suction hose 20, realizing a single waste collection. Thus, it circulates repeatedly to automatically collect the waste cut during each hot melt edge sealing.

[0053] The present utility model is provided with suction ports 12 and connectors 13 on both sides of the edge sealing mechanism 14, and connects an external negative pressure generating device and the waste collection container 50 through the suction hose 20, so as to conveniently suck the waste edges generated by the hot melt edge trimming of the edge sealing mechanism 14 directly into the suction hose 20, and finally collect them into the waste collection container 50, realizing the automatic collection and treatment of waste.

[0054] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
