In practical work process, after packing box overlay film after lower shovel smooths component 30 and heat-sealing component 50, complete to cover Connection after film is packed and is entered and close lightly in angular component 60, complete end face then during packing box is constantly pushed It closes lightly angle and closes lightly the end face seal movement behind angle, enter finally into end face flattener module 80, the pressing heat for completing section up and down is covered, Finally discharging enters next process, promotes the quality and qualification rate of overlay film, total in production line setting, from overlay film to Integrated setting is sealed, a feeding saves packing box intermediate transition and secondary resetting, improves work effect Rate saves manpower.

The course of work that lower shovel smooths component 30 is as follows: the second sprocket wheel of motor driven 312 rotates, under the action of chain, First sprocket wheel 311 and the second sprocket wheel 312 rotate synchronously, and during the first sprocket wheel 311 rotates, lower shovel cam 31 are driven to rotate, Lower shovel cam 31 is equipped with driving bearing 32, and in the low spot of lower shovel cam 31, driving bearing 32 is located at bottom, in lower shovel The high point of cam 31, driving bearing 32 are located at the top, and driving bearing 32 moves up and down, drives on the hoisting frame 33 hinged with it Lower movement during hoisting frame 33 moves up and down, drives lower shovel board 36 to move up and down, completion smooths box body two external films With cover, since lower shovel board 36 is equipped with bending section 363 and towards feed inlet, during charging constantly conveying, bending section The lower end of 363 pairs of box bodys smooths, and is sealed after smoothing, and improves the efficiency of film packaging, while improving heat-sealing Efficiency and quality, so that overlay film effect is more preferable, product is more attractive.

Close lightly that angular component 60 is completed for longitudinal four sides by film packaging and rear end is closed lightly the case where angle is completed and is configured, That is the state of Figure 11 closes lightly angle followed by the folding for completing end face, and packing box 601 coated with film is constantly pushed to bottom plate 65 On, under continuous push, packing box 601 constantly advances, and the distance between symmetrically arranged first frid 611 is equal to packing box 601 length, during continuous delivering, the front end of 601 end face of packing box is depressed, i.e., shown in Figure 12, packaging and entrance To after bottom plate 65, the upper end of film, which enters, closes lightly angle bit-avoiding slot 64, and the lower end of film enters the during continuous push One closes lightly chamfered groove 61, and with packing and being constantly pushed, the film of lower end is folded up under the action of first closes lightly chamfered groove 61, that is, is schemed Shown in 13, enter second close lightly chamfered groove 62 after, the upper end of film is in horizontality, does not have between third frid 631 and pressing plate 66 After having gap, packing box 601 to continue push, the upper end of film enters third and closes lightly chamfered groove 63, with being constantly pushed, film Upper end be folded down complete, i.e., shown in Figure 14, enter conveyer belt 67, conveyer belt 67 effect under, packing box 601 continues Push forward, side seal board 68 is heating plate, and side seal board 68 is mobile to packing box 601 under the action of cylinder 681, complete packaging and The heat-sealing movement behind angle is closed lightly in side, enters a process, and total is simple, closes lightly angular motion and makees to be not provided with power source by push, close lightly Angular accuracy is stablized, at low cost, closes lightly directly heat-sealing molding behind angle, good airproof performance.

The course of work of end face flattener module 80 is as follows: packing box is constantly pushed to the upper end of lower sealing plate 81, packing box After in place, the force-output shaft of lifting cylinder 85 stretches out, and lifter plate 83 is driven to move downward, and lifter plate 83 drives upper sealing plate 82 to transport downwards Dynamic, the upper end face contact with packing box, upper sealing plate 82 and lower sealing plate 81 realize the high temperature to packing box under the action of heating rod It flattens, if the driving force of lifting cylinder 85 is excessive, the upward pressure spring 86 of the meeting of upper sealing plate 82 avoids causing brokenly packing box It is bad, by the way that the specification of pressure spring 86 is arranged, upper sealing plate 82 can be limited to the pressure limit of packing box, guarantee that constant pressure heat-sealing covers, heat It is good to seal effect, and survivable packing box, promotes the qualification rate and packaging quality of product, in the process of running, guide rod 821 and the setting of guide post 851 can promote upper sealing plate 82 and move up and down precision, guarantee the precision and stabilization of total movement Property.

One embodiment of the present invention has been described in detail above, but content is only presently preferred embodiments of the present invention, It should not be considered as limiting the scope of the invention.Any changes and modifications in accordance with the scope of the present application, It should still be within the scope of the patent of the present invention.
