By integrating transmission, cutting, and positioning mechanisms, continuous conveying and precise cutting of film materials are achieved. However, existing new corrugated carton film cutting machines generally lack a coordinated control mechanism for film cutting and conveying actions, making it difficult to accurately match the cutting timing with the film material conveying position, which easily leads to cutting misalignment or repeated cutting.

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Further explanation, the air cylinder 3 in film cutting mechanism and shaping film cutter 5 can be cut to the corrugated box packaging film on conveying table 1.
[0026] As Figure 1 And Figure 4 Indicated, lifting plate 4 and shaping film cutter 5 are detachably connected between multiple bolts 17.
[0027] Further explanation, when shaping film cutter 5 appears abrasion or needs to replace different specifications of cutter, it can be conveniently and quickly disassembled and installed, reduces equipment downtime.
[0028] As Figure 1 And Figure 2 Indicated, conveying table 1 top is provided with conveying mechanism, conveying mechanism includes the fixed groove 6 of being opened in the top of conveying table 1, multiple conveying rollers 7 are rotatably connected on the inner side wall of fixed groove 6, conveying sleeve 8 is fixedly sleeved on the outer side wall of conveying roller 7, and adjacent two conveying rollers 7 are drivenly connected by belt 9.
[0029] Further, the conveying mechanism can convey the corrugated carton packaging film placed on the conveying sleeve 8, facilitating cutting.
[0030] As shown in Figure 1 and Figure 2 , the distance between the two adjacent conveying rollers 7 is the same.
[0031] Further, this design makes the conveying of the corrugated carton film by the conveying sleeve 8 more uniform, avoiding problems such as uneven film conveying and wrinkles caused by inconsistent spacing between the conveying rollers 7, and improving film cutting quality.
[0032] As shown in Figure 1 and Figure 2 , the film cutting mechanism and the conveying mechanism are connected through a linkage mechanism, which includes a vertical plate 10 fixedly installed on the top of the lifting plate 4, a rack 11 fixedly installed on the outer side wall of the vertical plate 10, a support plate 12 fixedly installed on the top of the gantry 2, a rotating shaft 13 rotatably connected to the outer side wall of the support plate 12, a chain 14 drivingly connected between the rotating shaft 13 and one of the conveying rollers 7, a gear 15 fixedly sleeved on the outer side wall of the rotating shaft 13, and the gear 15 and the rack 11 are meshingly connected.
[0033] Further, the film cutting mechanism and the conveying mechanism are connected through the linkage mechanism, realizing the coordinated cooperation of the film cutting action and the conveying action. When the film cutting mechanism performs the film cutting operation, the conveying mechanism will make corresponding actions synchronously, improving the production efficiency and the precision of the film cutting. The film cutting mechanism, the conveying mechanism and the linkage mechanism each have independent functions and structures, facilitating installation, debugging and maintenance.
[0034] As shown in Figure 2 , the outer side wall of the conveying roller 7 is sleeved with a pulley matched with the belt 9, and the outer side wall of the rotating shaft 13 and one of the conveying rollers 7 is sleeved with a chain disc matched with the chain 14.
[0035] Further, this design can ensure that the belt 9 and the chain 14 run stably during transmission, reduce the phenomenon of slipping, and improve the transmission efficiency.
[0036] As shown in Figure 1 , the top of the gantry 2 is provided with a sliding opening 16, and the outer side wall of the vertical plate 10 and the inner side wall of the sliding opening 16 are slidingly connected.
[0037] Further, this design provides accurate guidance for the up-and-down movement of the vertical plate 10, ensures the meshing accuracy of the rack 11 and the gear 15, and further improves the transmission stability of the linkage mechanism.
[0038] As shown in Figure 1 and Figure 3As shown, the top of the lifting plate 4 is provided with a limiting mechanism, which comprises a plurality of limiting holes 18 opened in the top of the lifting plate 4, and a T-shaped rod 19 is slidably connected to the inner side wall of the limiting hole 18, and a limit plate 20 is fixedly installed at the end of the T-shaped rod 19, and a reset spring 21 is slidably sleeved on the outer side wall of the T-shaped rod 19.
[0039] Further explanation, the T-shaped rod 19, the limit plate 20 and the reset spring 21 in the limiting mechanism can play a buffering role when the lifting plate 4 is lowered to cut the film, preventing the lifting plate 4 from descending too fast to damage the corrugated carton film and the shaped film cutting tool 5.
[0040] As shown in the figure, Figure 1 The two ends of the reset spring 21 are fixedly connected with the inner top of the T-shaped rod 19 and the top of the lifting plate 4, respectively.
[0041] Further explanation, when the lifting plate 4 rises, the reset spring 21 can make the limit plate 20 and the T-shaped rod 19 return to the initial position, ready for the next film cutting.
[0042] The function principle of the utility model can be described as follows:
[0043] Install the tool
[0044] According to the size and shape of the corrugated carton packaging film to be cut, select a suitable shaped film cutting tool 5, use a tool to unscrew the bolt 17 at the bottom of the lifting plate 4 for fixing the tool, install the selected tool at the bottom of the lifting plate 4, and then tighten the bolt 17 to ensure that the tool is firmly installed.
[0045] Place the packaging film
[0046] Place the corrugated carton packaging film on the conveying sleeve 8 of the conveying mechanism, so that the starting end of the packaging film is close to the lower position of the shaped film cutting tool 5.
[0047] Start the cutting operation
[0048] Start the cylinder 3, the piston end of the cylinder 3 starts to extend, pushes the lifting plate 4 to slide downward along the inner wall of the gantry 2, as the lifting plate 4 descends, the vertical plate 10 also moves downward, at this time, the rack 11 on the outer side wall of the vertical plate 10 starts to engage with the gear 15, driving the gear 15 to rotate.
[0049] The rotation of the gear 15 is transmitted to the chain 14 through the rotating shaft 13, and the chain 14 drives the conveying roller 7 connected thereto to rotate, since the adjacent conveying rollers 7 are drivingly connected through the belt 9, therefore all the conveying rollers 7 start to rotate synchronously, and the conveying sleeve 8 conveys the corrugated carton packaging film.
[0050] During the descending of the lifting plate 4, the T-shaped rod 19 slides in the limiting hole 18, and the reset spring 21 is compressed. When the limiting plate 20 contacts the corrugated box packaging film on the conveying roller 7, the gear 15 and the rack 11 are not engaged at this time, the conveying roller 7 stops rotating, the limiting plate 20 positions the corrugated box packaging film, prevents the packaging film from moving during cutting, and the lifting plate 4 continues to descend, and the shaped film cutting tool 5 cuts the positioned corrugated box packaging film.
[0051] cutting completion and reset
[0052] After the cutting is completed, the piston end of the control cylinder 3 is retracted to drive the lifting plate 4 to rise, and as the lifting plate 4 rises, the vertical plate 10 moves up, the rack 11 and the gear 15 are engaged again, the conveying roller 7 starts rotating again, and the packaging film continues to be conveyed to prepare for the next cutting.
[0053] During the rising of the lifting plate 4, the elastic force of the reset spring 21 gradually restores the limiting plate 20 and the T-shaped rod 19 to the initial position, waiting for the next cutting operation.
[0054] continuous operation and replacement of the tool
[0055] The above cutting steps are repeated to perform continuous film cutting operation. When the shaped film cutting tool 5 is worn or needs to be replaced with a tool of different specifications, stop the equipment operation, unscrew the bolt 17 according to the tool installation steps, replace the new tool, and then continue the operation.
[0056] shutdown of the equipment
[0057] When the film cutting operation is completed, the power of the equipment is turned off, the residual film scraps on the conveying table 1 are cleaned, and the equipment is necessary maintained and maintained.
[0058] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
