Description of the embodiments

The following description of the embodiments of the present utility model will be given with reference to the accompanying drawings and examples.

The EVA film slitting device comprises a frame 1, one end of the frame 1 is provided with a roller 2 capable of holding an EVA film to be slit, the other end of the frame is provided with a fixing component 3, the fixing component 3 comprises an opening 31 and a pressing block 32 arranged in the opening 31, the opening 31 is provided with a mounting groove 33 corresponding to the pressing block 32, a first air cylinder 34 connected with the pressing block 32 is arranged in the mounting groove 33, a discharge hole 4 is formed in the frame between the roller 2 and the fixing component 3, one side of the discharge hole 4 is provided with a slitting component 5, the slitting component 5 comprises a cutter frame 51, two slitting rollers 52 arranged on the cutter frame 51 in parallel and annular blades 53 sleeved on the slitting rollers 52, the slitting rollers 52 are rotatably arranged and are connected with servo motors, knife tips of the two opposite annular blades 53 on the slitting rollers 52 are in contact with each other, the frame 1 is provided with a supporting plate 6 corresponding to the cutter frame 51, the supporting plate 6 is connected with a second air cylinder 7, and the second air cylinder 7 is connected with the cutter frame 51. During the use, can pull out the EVA film that waits to cut from roller 2, make it get into opening 31, at this moment first cylinder 34 promotes briquetting 32, make it fix EVA film in opening 31 department with opening 31 cooperation, open servo motor, drive and cut roller bearing 52 and rotate, thereby make annular blade 53 rotate, then second cylinder 7 promotes knife rest 51 and makes pivoted cut roller bearing 52 and annular blade 53 remove, cut the EVA film, the EVA film that finishes cutting can leave from discharge gate 4 at last, wherein, the knife tip of two annular blades 53 that cut opposite on roller bearing 52 is inconsistent, cut the film through the cooperation of knife tip, and the annular blade 53 rotation of counterbalance, just like scissors shearing, the condition that the cutting is continuous when having solved the EVA film and cutting, and cutting efficiency is high moreover.

It should be noted that the two slitting rollers 52 are turned in unison and face the direction of pushing by the second cylinder, so as to facilitate slitting of the EVA film.

In addition, the slitting assembly 5 can be arranged in parallel with the axial direction of the roller 2, can also be arranged perpendicular to the axial direction of the roller 2, or two groups of slitting assemblies 5 are arranged, one group is arranged parallel with the axial direction of the roller 2, and the other group is arranged perpendicular to the axial direction of the roller 2, so that the slitting assembly can be used for transversely or longitudinally slitting the EVA film. The slitting assembly 5 of this embodiment and the accompanying drawings can be arranged perpendicularly to the axial direction of the roll 2

The annular blade 53 is detachably provided on the slitting roller 52 and is movable on the slitting roller 52. The number of the annular blades 53 on the slitting roller 52 can be increased or decreased, the positions of the annular blades 53 can be adjusted according to the size of the EVA film to be slit, and the processing efficiency is improved.

As shown in fig. 3, a connecting hole 8 is provided in the middle of the annular blade 53, a rubber fixing sleeve 9 is fixedly provided in the connecting hole 8, and the annular blade 53 is sleeved on the slitting roller 52 through the rubber fixing sleeve 9. This arrangement allows the annular blade 53 to be secured to the slitting roller 52 by the rubber fixing sleeve 9, while the rubber fixing sleeve 9 has a certain elasticity that allows it and the annular blade 53 to move on the slitting roller 52.

It should be noted that, the size of the rubber fixing sleeve is slightly smaller than the diameter of the slitting roller 52, and the rubber fixing sleeve is arranged on the slitting roller 52 to generate elastic deformation, so that the rubber fixing sleeve is more tightly connected with the slitting roller 52.

The slitting roller 52 is marked with a scale of length units. This arrangement allows the distance between the annular blades 53 to be adjusted according to the marked scale, so that the cut EVA film is more accurate in size.

And a collecting table 10 capable of collecting the cut EVA films is arranged below the discharge hole 4. The EVA film that sets up like this can make to leave from discharge gate 4 falls on the platform 10 that gathers materials, conveniently collects the EVA film that the cutting finishes.
