The controller 11 uses a PLC controller. The rotating shaft 6 on which the film roll 5 is placed; the rear end of the frame 3 is also rotatably provided with an active clamping and discharging roller 7 and a driven clamping and discharging roller 8. The active clamping and discharging roller 7 and the driven The clamping and discharging rollers 8 are connected by a transmission gear 10, and the output shaft of the servo motor 9 is connected with a gearbox 27, and the gearbox 27 and the active clamping and discharging rollers 7 are connected by a transmission belt power;

[0034] The frame 3 is provided with a plurality of photoelectric sensors 12 surrounding the drum 4, the photoelectric sensor 12 is connected to the signal output terminal of the controller 11, and the rear end of the frame 3 is provided with a plurality of photoelectric sensors 12 surrounding the active clamping and feeding roller 7 The photoelectric sensor 12 is connected to the signal input end of the controller 11, and the rotating shafts of the roller 4 and the active clamping and feeding roller 7 are both provided with a baffle 13 that cooperates with the photoelectric sensor 12.

[0035] Embodiment 2

[0036] As a preferred embodiment of the present invention, this embodiment discloses a concrete protective film laying device, the specific structure is as Figure 2 to Figure 5 As shown, it includes a paving trolley 1 and a fixed pile 2. The paving trolley 1 includes a frame 3, and two U-shaped support frames 19 that cooperate with each other are fixedly arranged on both sides of the tail of the frame 3, and the tail of the frame 3 is also fixed. A rotating shaft 6 is provided. A plurality of support frames 21 adapted to the packaging drum of the film roll 5 are evenly arranged in the middle of the rotating shaft 6, and both ends of the rotating shaft 6 are provided with rolling bearings 20 adapted to the U-shaped support frame 19. The open end bracket of the shaped support frame 19 is erected with a rotating shaft 6; at the same time, the tail of the frame 3 is also rotatably provided with an active clamping and discharging roller 7 and a driven clamping and discharging roller 8 that cooperate with each other, the active clamping and discharging roller 7 The clamping surface of the driven clamping and unwinding roller 8 is covered with only a sponge non-slip cover 18;

[0037] Further, a guide roller 22 is also rotatably arranged at the end of the frame 3. The guide roller 22 is located behind the active clamping and unwinding roller 7 and the driven clamping and unwinding roller 8, and the installation height of the guide roller 22 is lower than that of the active Clamp the discharge roller 7 to ensure that the film is guided to the concrete surface; at the same time, at the end of the frame 3 through the traction rod 33, a laminating roller 25 is pulled, and the laminating roller 25 rolls on the concrete surface to ensure the film and The concrete surface is laminated, and the surface of the film pressing roller 25 is evenly provided with a plurality of film piercing needles 26;

[0038] Further, a sliding rod 14 is also provided between the guide roller 22 and the active clamping and discharging roller 7, and a cutting knife seat 15 is slidably provided on the sliding rod 14, and a cutting knife 16 is hinged on the cutting knife seat 15 and The cutting blade 16 is fixed by the locking bolt 17.

[0039] Further, the upper part of the fixed pile 2 is provided with a compression groove 28 and a compression block 29 that cooperate with each other, and the fixed pile 2 is hinged with a locking hook 30 and a limiting pile 31 for fixing the compression block 29. A plurality of grouting nails 32 are evenly arranged at the bottom of the fixed pile 2.

[0040] When the present invention is used, the film roll is first placed on the support frame of the rotating shaft, then the rolling bearings at both ends of the rotating shaft are placed on the U-shaped support frame at the end of the frame, and one end of the film is pulled out and discharged from the active clamping The roller and the driven clamping and unwinding roller pass through, and then pass through the bottom of the guide roller and the film pressing wheel, and finally are fixedly installed and fixed on the fixed pile by the compression block, and the fixed pile is placed at one end of the concrete ground to be laid. Workers pull the paving trolley by pulling the handrails of the cart. During the movement of the paving trolley, the photoelectric sensor continuously monitors the movement speed of the paving trolley through the cooperation with the baffle. The moving speed of the laying trolley is adapted, and the film is finally released quickly; compared with the prior art, the present invention not only greatly improves the efficiency of film release, but also puts the film neatly, which not only reduces the secondary maintenance procedures, but also avoids The appearance of blank areas for laying has greatly improved the quality of laying.
