Description

Technical Field

[0001] The invention relates to the technical field of logistics transportation, in particular to a continuous packaging machine for logistics. Background Art

[0002] Logistics refers to the entire process of planning, implementing and managing the transportation, storage and distribution of raw materials, semi-finished products, finished products or related information from the place of production to the place of consumption in order to meet customer needs.

[0003] With the improvement of living standards and the development of the Internet, people's demand for online shopping has increased, and at the same time, the quality requirements for online shopping products are higher. For this reason, it is necessary to seal and package the goods during transportation. Online shopping products are generally packaged in cartons, which is convenient for the recycling of cartons in the later stage and reduces pollution. Among them, the packaging process involves product transfer, positioning of multiple groups of product combinations, folding of cartons, placing combined products into cartons, sealing, etc. The packaging and boxing of products will waste a lot of manpower in circulation and transportation and personnel work, and the efficiency cannot be guaranteed. Conventional corrugated cartons are generally used for packaging and boxing. Conventional corrugated cartons have two inner covers and two outer covers. When sealing the box, it is necessary to fold the two inner covers first and then fold the two outer covers, and finally seal the connection of the two outer covers with tape, thereby realizing the sealing operation of the carton. In the process of packing some special items with heavy weight and spikes, in order to avoid the loss of items caused by the rupture of the carton during transportation, it is usually necessary to add a buffer layer in the carton to increase the wear resistance, anti-rupture and other properties of the carton.

[0004] The existing baling machine has low packing efficiency and cannot adjust the packing speed in real time according to the moving speed of the packaging box. It also requires manual operation when gluing and sealing the packaging box or turning the packaging box. The workload of the workers is large, which wastes manpower and is costly. Therefore, a continuous baling machine for logistics is proposed. Summary of the invention

After being bent, the packaging box enters the sealing chamber and continues to move to the right. At this time, the head end of the tape wheel passes through the reversing roller and hangs down to the left side of the rolling wheel, with its adhesive surface facing the packaging box. When the packaging box moves to contact the tape, the tape is adhered to the surface of the packaging box to seal it. The rolling wheel is thrust to the right and rotates to the right, causing the movable rod to rotate to the right around the reversing roller. At this time, the telescopic rod is shortened, and the first return spring is compressed, which produces an elastic force in the opposite direction on the movable rod.

[0031] The flip frame 51 is disposed at a right angle, the bottom edge of the flip frame 51 is disposed flush with the top of the transmission chain 6 , and the flip frame 51 is disposed between a pair of the transmission chains 6 .

[0032] A second return spring 57 is connected between the right slider 54 and the right side plate 50, and the second return spring 57 is arranged around the outside of the slide bar 55. When the flip rod 56 rotates, it generates a rightward thrust on the right slider 54, pushing the right slider 54 to slide toward the right end of the slide bar 55. At this time, the second return spring 57 is compressed to generate an elastic force in the opposite direction. When the flip is completed, the right slider 54 is reset under the action of the elastic force, driving the flip rod 56 and the flip frame 51 to reset accordingly, so that the flip frame 51 can be automatically reset. Working principle: when in use, the driving motor 5 is started, so that the driving roller 4 starts to rotate. When the driving roller 4 rotates, it drives the transmission chain 6 meshing therewith to start rotating, so that the driven roller 7 connected to the other end of the transmission chain 6 starts to rotate. When the transmission chain 6 rotates, it drives the push block 9 outside it to start moving, pushing the packaging box 10 to enter the packaging bin 15, the sealing bin 16 and the flip bin 17 in sequence. When the packaging box 10 moves, the transmission roller 19 can assist the packaging box 10 to move. When the driven roller 7 rotates, it drives the rotating shaft 8 to rotate accordingly, so that the driving wheel 11 at the front end of the rotating shaft 8 starts to rotate. When the driving wheel 11 rotates, it drives the driven wheel 13 to start rotating through the transmission belt 12 meshing therewith, so that the transmission shaft 14 starts to rotate. When the transmission shaft 14 rotates, it drives the rotating disk 20 to start rotating. When the rotating disk 20 rotates, it drives the rotating rod 21 to start rotating. When the rotating rod 21 rotates, it drives the vertical rod 22 at the bottom to move up and down periodically, wherein the movement cycle of the vertical rod 22 matches the movement speed of the packaging box 10. When the packaging box 10 moves to the bottom of the vertical rod 22, the vertical rod 22 moves to When the connecting rod 25 moves downward, it drives the bottom mounting plate 24 to move downward, so that the connecting rod 25 at the bottom of the side of the mounting plate 24 moves downward. When the connecting rod 25 moves downward, it drives the bottom cross bar 26 to move downward. When the cross bar 26 moves downward, it drives the gear 29 to move downward. When the gear 29 moves downward, it generates relative movement with the rack 28, so that the gear 29 starts to rotate, driving the lever 30 on the other side of the gear 29 to rotate downward, and bending the bending part at the top of the packaging box 10, wherein the height of a pair of levers 30 perpendicular to the movement direction of the packaging box 10 is higher than that of the other pair of levers 30, so that the bending parts on both sides of the movement direction of the packaging box 10 can be bent at the end to avoid interference and facilitate subsequent sealing; after bending, the packaging box 10 continues to move, and when passing the bottom of the first wedge block 32, the bottom end of the first wedge block 32 can apply downward pressure to the bending line to avoid rebound of the bending part. Through the above steps, automatic packaging and bending of the packaging box 10 can be realized, and the packaging speed and the movement speed of the packaging box 10 can be adaptively adjusted.

[0033] When the vertical rod 22 moves downward, it drives the connecting rod 31 to move downward, so that the movable end 37 at the other end of the connecting rod 31 moves downward, driving the knife seat 38 and the cutting knife at the bottom of the movable end 37 to move downward periodically. After being bent, the packaging box 10 enters the sealing chamber 16 and continues to move to the right. At this time, the head end of the tape wheel 43 passes through the reversing roller 44 and hangs on the left side of the rolling wheel 46, and its adhesive surface faces the packaging box 10. When the packaging box 10 moves to contact with the tape, the tape is adhered to the surface of the packaging box 10 to seal it. The rolling wheel 46 is pushed to the right and rotates to the right, so that the movable rod 45 rotates to the right around the reversing roller 44. At this time, the telescopic rod 4 8 is shortened, and the first return spring 49 is compressed, generating an elastic force in the opposite direction to the movable rod 45. Under the action of the elastic force, the rolling wheel 46 is tightly attached to the surface of the pasting portion of the packaging box 10, so that the tape fits tightly to the packaging box 10, thereby improving the sealing effect. When the sealing is completed, the cutting knife moves downward to cut the tape, and the packaging box 10 enters the sealing chamber 16 after being bent. When passing the bottom of the second wedge block 34, the bottom end of the second wedge block 34 can apply downward pressure to the bent portion, so that the bent portion remains flat during the sealing process to avoid inadequate sealing. Through the above steps, the tape can be cut synchronously while improving the sealing effect.

[0034] After the packaging box 10 is sealed, the transmission chain 6 drives the packaging box 10 to continue moving. When the packaging box 10 moves to contact the inner wall of the flip frame 51, the flip frame 51 is pushed to the right and rotates to the right around the connection between the back plate 52 and the left slider 53. At this time, the flip rod 56 connected to the other end of the back plate 52 rotates in the opposite direction around the right slider 54, thereby driving the flip frame 51 to start flipping, so that the packaging box 10 on the upper part of the flip frame 51 starts to flip. When the flip rod 56 rotates, it generates a rightward thrust on the right slider 54, pushing the right slider 54 to slide toward the right end of the slide rod 55. At this time, the second return spring 57 is compressed to generate an elastic force in the opposite direction. When the flip is completed, the right slider 54 is reset under the action of the elastic force, driving the flip rod 56 and the flip frame 51 to reset accordingly, thereby realizing the automatic reset of the flip frame 51. Through the above steps, the automatic flipping of the packaging box 10 is realized, which can effectively reduce the workload of workers and reduce manpower waste while improving efficiency.
