DETAILED DESCRIPTION

[0022] Since the sealing effect of film cutting after film coating on the surface of square boxes is not good and the manual operation efficiency is relatively low, we have designed a film cutting mechanism based on the defects of the existing technology, which can fully perform hot cutting on the square boxes, has low manual participation, good film cutting effect, and is easy for people to use.

[0023] In order to make the technical solution more clear to those skilled in the art, Figure 1-2The technical scheme of the present invention is described in detail: the present invention first comprises a fixed bottom plate 1 which plays a supporting role. The fixed bottom plate 1 is placed horizontally, and a bottom cutting knife mechanism and a side cutting knife mechanism are arranged on the fixed bottom plate 1 for hot cutting the film on the outer packaging of the square box. The process is automated, and there is no need to manually hold the square box to hot cut the film on it; two bottom cutting knife mechanisms are provided and symmetrically arranged on both sides above the fixed bottom plate 1, wherein two side cutting knife mechanisms are respectively provided on the bottom cutting knife mechanisms on both sides and the two are distributed front and back, that is, a total of four side cutting knife mechanisms are provided and arranged in a square shape, with a length of square. The side cutter mechanisms on the same horizontal line work simultaneously, and then the side cutter mechanisms on another horizontal line start working simultaneously, the heat cutting and sealing effect is good, and it is convenient for people to use; based on the fact that the size of the square box is not fixed, we also design a bottom cutter length adjustment mechanism and a side cutter width adjustment mechanism on this basis to adjust the distance between the bottom cutter 25 and the side cutter 46 set in pairs, so as to facilitate better packaging of the square box. The bottom cutter mechanism, the bottom cutter length adjustment mechanism, the side cutter mechanism, and the side cutter width adjustment mechanism are described in detail below:

[0024] The bottom cutter mechanism includes a vertical plate 21 arranged above the fixed bottom plate 1, a first cylinder fixing seat 22 arranged on the vertical plate 21, a first cylinder 23 arranged on the first cylinder fixing seat 22, a first push rod connected to the first cylinder 23, a lower cutter fixing plate 24 fixedly connected to the first push rod, and a lower cutter 25 arranged on the lower cutter fixing plate 24; the first cylinder fixing seat 22 is fixedly connected to the vertical plate 21, the first cylinder 23 is fixedly installed on the first cylinder fixing seat 22, the lower cutter 25 is fixedly connected to the lower cutter fixing plate 24, and the blade of the lower cutter 25 is aligned with the bottom of the square box; the first cylinder 23 can drive the first push rod to move up and down, and when the first push rod moves, it can drive the lower cutter fixing plate 24 to move, and then the lower cutter 25 moves accordingly, so as to perform hot cutting on the film below the square box.

[0025] The bottom cutter length adjustment mechanism includes a first linear module 31, a first slider fixing plate 32 symmetrically arranged on both sides above the first linear module 31, a first slider 33 arranged on both sides below the first slider fixing plate 32, a movable base plate 34 arranged below the first linear module 31, and slide rails 35 arranged on both sides above the movable base plate 34 for facilitating the stable movement of the first slider 33 on the movable base plate 34; the upper surface of the first slider 33 is fixedly connected to the lower surface of the first slider fixing plate 32, and the first slider 33 is slidably connected to the slide rail 35. The first linear module 31 can control the bottom cutter mechanism to move laterally thereon according to the length of the square box, so that the bottom cutters on both sides can perform hot cutting of the film below the square box well; wherein the movement of the first slider 33 on the slide rail 35 can make the bottom cutter mechanism move stably under the drive of the first linear module 31, thereby reducing the deviation; further, for some square boxes with relatively high heights, The bottom cutting knife mechanism is more laborious to use, so we set a lifting mechanism under the movable bottom plate 34, which includes a second cylinder 36 and a second push rod connected to the second cylinder 36; the second cylinder 36 is fixedly installed on the fixed bottom plate 1, and the upper end of the second push rod is fixedly connected to the lower surface of the movable bottom plate 34; guide columns 37 are symmetrically arranged around the lower side of the movable bottom plate 34, and a linear bearing 38 is sleeved on the guide column 37, and the linear bearing 38 is fixedly installed on the fixed bottom plate 1, and the upper end of the guide column 37 is fixedly connected to the lower surface of the movable bottom plate 34, and a limit block 39 is provided between adjacent guide columns 37, and the lower end of the guide column 37 is fixedly installed on the upper surface of the limit block 39; the second cylinder 36 can drive the second push rod to move up and down, and the up and down movement of the second push rod can drive the movable bottom plate 34 to move up and down, and then can drive the bottom cutting knife mechanism to move up and down, so that the bottom cutting knife thereon can better perform hot cutting on the bottom of the square box.

[0026] The side cutting knife mechanism includes a side cutting vertical plate 41 arranged on the vertical plate 21, a third cylinder mounting plate 42 arranged on the side cutting vertical plate 41, a third cylinder 43 arranged on the third cylinder mounting plate 42, a third push rod connected to the third cylinder 43, a side cutting fixing plate 44 fixedly connected to the third push rod, a side cutting heat insulation block 45 arranged on the side cutting fixing plate 44, and a side cutting knife 46 arranged on the side cutting heat insulation block 45; the third cylinder mounting plate 42 is fixedly mounted on the side cutting vertical plate 41, the third cylinder 43 is fixedly mounted on the third cylinder mounting plate 42, the side cutting heat insulation block 45 is fixedly mounted on the side cutting fixing plate 44, and the side cutting knife 46 is arranged on the side cutting heat insulation block 45. The knife 46 is fixedly mounted on the side-cutting heat-insulating block 45, and the blade of the side-cutting knife 46 faces the side of the packaging box; wherein, the third cylinder 43 can drive the third push rod to move, and the movement of the third push rod can drive the side-cutting fixing plate 44 to move, and when the side-cutting fixing plate 44 moves, it can drive the side-cutting heat-insulating block 45 to move, and then can drive the side-cutting knife 46 to move, so that the film on the side of the box can be hot-cut, wherein the side-cutting knife mechanisms on the same horizontal line on the bottom cutting knife mechanisms on both sides work at the same time, so that the side of the box can be hot-cut at the same time, and then the side of the box can be hot-cut again, so that the box can be better hot-cut and sealed.

[0027] The side cutter width adjustment mechanism is arranged on the vertical plate 21, and includes a second linear module 61 and side cutting sliding bases 62 arranged on both sides above the second linear module 61; the second linear module 61 is installed on the vertical plate 21, and the side cutting sliding bases 62 on both sides are respectively fixedly connected to the side cutting vertical plates 41 on the side cutting mechanism on both sides; the second linear module 61 can drive the side cutting sliding base 62 to move thereon, and when the side cutting sliding base 62 moves, it can drive the side cutting mechanism thereon to move, so as to adapt to the width of the square box and thus better perform heat cutting and sealing on it.

[0028] When the side cutting knife 46 mechanism is working, the film on the side of the square box may and can be completely attached to the side of the square box. At this time, if the packaging effect of the square box is not good when working directly, it needs to be re-packaged, which seriously affects the work efficiency. Therefore, we also set a side sorting mold mechanism on one side of the side cutting knife mechanism, which mainly includes a fourth cylinder 51, a fourth push rod connected to the fourth cylinder 51, a second slider 52 fixedly connected to the fourth push rod, and a side sorting module 53 connected to the second slider 52. The fourth cylinder 51 is fixedly installed on the side cutting vertical plate 41, and the side sorting module 53 is placed vertically with the side cutting knife 46. Among them, the fourth cylinder 51 can drive the fourth push rod to move, and the movement of the fourth push rod can drive the movement of the second slider 52, and the movement of the second slider 52 can drive the side sorting module 53 to move, so as to flatten the film on the side of the square box so that it can be completely attached to the side of the square box. Then the side cutting knife mechanism can be controlled to work and the film on the side of the square box can be hot-cut.

[0029] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
