Meanwhile, the top support roller b2 and the support surface b30 are arranged in a disconnected manner, and when the front end of the film sheet m is peeled, the rear end of the film sheet m is positioned behind the top support roller b 2. Thus, when the film enters the pre-peeling area, the film is kept in a stable state and keeps inertial motion, so that when the bottom film passes through the peeling roller, the film keeps translating and falls into the film receiving frame in front.
In this example, extension ears b33 are formed on both sides of the rear end of the peeling support platform b3, and both end portions of the knock-up roller b2 are rotatably connected to the two extension ears b33, respectively.
In addition, a positioning frame G is further arranged at the discharging end part, wherein the top supporting roller b2 is positioned on the positioning frame G, the top surface of the top supporting roller b2, the supporting surface b30 and the bottom surface of the protective film transmission channel are arranged in a flush mode, and the peeling roller is located below the front side of the top supporting roller. In this case, the alignment of the three surfaces results in a zero-damage peeling of the film at an optimum angle.
Meanwhile, in consideration of different working requirements, the discharging end part is correspondingly provided with a plurality of hook grooves E which are arranged side by side from top to bottom, the positioning frame G comprises a hanging rod G1 hung on one hook groove E and hanging arm rods G2 positioned at two ends of the hanging rod G1, and the upper end part and the lower end part of each hanging arm rod G2 are respectively connected with the end parts of the corresponding hanging rod G1 and the top support roller b2 at the same side. According to the selectable hook groove arrangement, the actual requirement is met.
In this example, the upper end of the arm hanging rod g2 is relatively fixedly connected with the end of the arm hanging rod g1 through a rod sleeve g3 and a locking bolt g4, and the arm hanging rods g2 on the two sides are arranged in parallel.
And the bottom film furling unit C is used for furling the bottom film d after stripping.
Specifically, the bottom film furling unit C includes a furling roller C1 and a tension guide roller C2 located at the lower portion.

2) The film and the bottom film are fed into the cutting system, the edge of the film is firstly subjected to roll cutting through a waste edge roll cutting unit, the roll cutting thickness is equal to the thickness of the film, then the film is conveyed out of the waste edge roll cutting unit, the film continues to move forward along with the bottom film after the roll cutting, and the cut waste edge is separated from the bottom film and is recovered under the winding of a waste edge collecting unit;
3) The film and the bottom film with the waste edges cut by the roller enter the middle excess part rolling cutting unit, the excess part rolling cutting is carried out, the rolling cutting thickness is the thickness of the film, then the film is spread out from the middle excess part rolling cutting unit, the film continues to move forwards along with the bottom film after the rolling cutting, meanwhile, the top support roller supports the cut part against the surface of the film, then the cut part is stuck out and wound by a sticky belt moving in the same direction, and the film and the bottom film which are cut by the roller are sent into a film receiving system;
4) The diaphragm and the basement membrane that get into the diaphragm and receive material system, basement membrane downstream behind the supporting surface of top supporting roller and peeling off supporting platform, the diaphragm gets into the district of peeling off in advance and with the peeling off of basement membrane small angle, the diaphragm keeps inertia linear motion level forward this moment, until basement membrane downstream to peel off the district after, diaphragm rear portion level support is on top supporting roller and supporting surface, the diaphragm continues to move ahead and with the basement membrane after progressively separating, fall into the diaphragm receipts material frame in the place ahead, and the basement membrane is by the roll-up.
In summary, the present embodiment has the following advantages:
1. the damage of the bottom film is avoided through quantitative roll cutting, and simultaneously, the waste edges and redundant waste materials can be effectively recycled on line, so that the continuous processing of the protective film is completed;
2. on the premise of realizing stable stripping, the contact between the basement membrane and the pre-stripping surface and the stripping surface is reduced, and the abrasion of the basement membrane is reduced;
3. the top surface of the top supporting roller, the supporting surface and the bottom surface of the protective film transmission channel are arranged in a flush manner, so that the zero-damage stripping of the membrane is realized at an optimal angle;
4. when the film enters the pre-peeling area, the film is kept in a stable state and keeps inertial motion, so that when the bottom film passes through the peeling roller, the film keeps translating and falls into the film receiving frame in front;
5. the membranes are aligned and stacked in the stacking area with respect to the front-back direction.
The present invention has been described in detail in order to enable those skilled in the art to understand the invention and to practice it, and it is not intended to limit the scope of the invention, and all equivalent changes and modifications made according to the spirit of the present invention should be covered by the present invention.
