A separation platform, a separation component, a first guiding roller group, and a second guiding roller group are arranged on the mounting base plate. The separation component is erected above the separation platform. The first guiding roller group and the second guiding roller group are respectively located on both sides of the separation platform. The separation component includes a first side frame, a second side frame, and a screw rod. Multiple groups of cutter head components are arranged on the screw rod. Sliding frames and electric cylinders are respectively arranged on both sides of the upper end of the mounting base plate. The push rod of the electric cylinder is connected to the second side frame, and the first side frame is slidably connected with the sliding frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a PE film separating mechanism, which includes a mounting base plate 1. A separating platform 2, a separating component 3, a first guide roller group 4, and a second guide roller group 5 are arranged on the mounting base plate 1. The separating component 3 is erected above the separating platform 2. The first guide roller group 4 and the second guide roller group 5 are respectively located on both sides of the separating platform 2. The separating component 3 includes a first side frame 31, a second side frame 32, and a screw 33. Multiple cutter head assemblies 34 are arranged on the screw 33. Slide frames 11 and electric cylinders 12 are respectively arranged on both sides of the upper end of the mounting base plate 1. The push rod of the electric cylinder 12 is connected to the second side frame 32. The first side frame 31 is slidably connected to the slide frame 11. When the electric cylinder 12 works, it can drive the second side frame 32 to axially drive, and synchronously drive the first side frame 31 to slide relative to the slide frame 11, so as to flexibly adjust the height position of the separating component 3.

[0024] A separating mechanism is arranged in the previous step of the PE film cutting mechanism. The PE film passes through the gap between the separating platform 2 and the separating component 3. The electric cylinder 12 works to drive the separating component 3 to move downward. Multiple cutter head assemblies 34 of the separating component 3 move downward synchronously and contact and press down on the PE film. At this time, there is a certain frictional force between the PE film and the multiple cutter head assemblies 34. The separating cutter head 343 is rotatably connected to the sliding sleeve 341. When the PE film moves under the drive of an external force, the separating cutter head 343 is driven to rotate by relying on this frictional force, and a cutting indentation is pressed on the surface of the film body, realizing the separation of the PE film, which is beneficial to the subsequent cutting of the PE film.

[0025] The distance between the multiple cutter head assemblies 34 and the separating platform 2 is controlled and driven by the electric cylinder 12, so that the separating mechanism is applicable to PE films of different thicknesses. It can adjust the distance between the cutter head assembly 34 and the separating platform 2 according to the thickness of the PE film, and can also control the separating pressure and adjust the separating force by controlling the height position of the cutter head assembly 34 to meet different use requirements.

[0026] Among them, the cutter head assembly 34 includes a sliding sleeve 341. A through hole 342 is opened on the sliding sleeve 341. The sliding sleeve 341 of the cutter head assembly 34 is slidably sleeved on the screw 33.

[0027] Among them, the cutter head assembly 34 and the screw 33 are fixed by a locking nut 35.

[0028] One set of cutter head assemblies 34 corresponds to two sets of locking nuts 35. The two sets of locking nuts 35 are respectively located at both ends of the sliding sleeve 341 of the cutter head assembly 34. The cutter head assembly 34 is fixed on the screw 33 by the two sets of locking nuts 35 to maintain stability.

[0029] Loosen the locking nut 35 to release the fastening force between the cutter head assembly 34 and the screw 33. At this time, the position of the cutter head assembly 34 can be adjusted. After the adjustment is completed, tighten the locking nut 35 again to maintain stability.

[0030] The positions of multiple sets of cutter head assemblies 34 are adjustable. By adjusting the spacing between adjacent cutter head assemblies 34, the splitting spacing can be adjusted accordingly. The structure between the cutter head assembly 34 and the screw 33 is detachable, which is convenient for maintaining the cutter head assembly 34.

[0031] Among them, the cutter head assembly 34 includes a splitting cutter head 343. The splitting cutter head 343 is rotatably connected to the sliding sleeve 341. When the PE film moves under the drive of an external force, the splitting cutter head 343 is driven to rotate by relying on the release of the frictional force. The splitting cutter head 343 rolls on the surface of the film body to press out cutting indentations, realizing splitting.

[0032] Among them, both ends of the screw 33 respectively penetrate through the first side frame 31 and the second side frame 32. The screw 33 is fixed to the first side frame 31 through a locking bolt 36, and the screw 33 is fixed to the second side frame 32 through a locking bolt 36. The connection between the screw 33 and the first side frame 31 and the second side frame 32 is detachable, which is convenient for installing and disassembling the screw 33.

[0033] Among them, the first guide roller group 4 includes a first roller frame 41 and a first rotating roller 42. The first roller frame 41 is rotatably connected to the first rotating roller 42, and the PE film is guided by the first rotating roller 42.

[0034] Among them, the second guide roller group 5 includes a second roller frame 51 and a second rotating roller 52. The second roller frame 51 is rotatably connected to the second rotating roller 52, and the PE film is guided by the second rotating roller 52.

[0035] Among them, legs 21 are welded and fixed to both sides of the lower end of the splitting platform 2. The splitting platform 2 is fixed to the mounting base plate 1 through the legs 21.

[0036] Among them, a splitting processing position is formed between the splitting platform 2 and the splitting assembly 3. When the film body passes through the splitting processing position, the splitting cutter head 343 rolls on the surface of the film body to press out cutting indentations.

[0037] Working principle: During use, according to the usage requirements, the positions of the cutter head assemblies 34 are adjusted. The PE film passes through the gap between the separating platform 2 and the separating assembly 3. The first guide roller group 4 and the second guide roller group 5 guide the PE film. The electric cylinder 12 works to drive the separating assembly 3 to move downward. Multiple cutter head assemblies 34 of the separating assembly 3 move downward synchronously and contact and press down on the PE film. At this time, there is a certain frictional force between the PE film and the multiple cutter head assemblies 34. The separating cutter head 343 is rotatably connected to the sliding sleeve 341. When the PE film moves under the drive of an external force, the separating cutter head 343 is driven to rotate by the action of this frictional force. Multiple separating cutter heads 343 press cutting indentations on the surface of the film body, realizing the separation of the PE film.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
