[0024] The right frame 12 is fixedly connected to the guide cylinder 22 , the guide cylinder 22 is threadedly connected to the adjusting screw 21 , the adjusting screw 21 is bearing-connected to the mounting seat of the gap adjusting roller 24 , and the mounting seat of the gap adjusting roller 24 is nested in the guide cylinder 22 .

[0025] The guide cylinder 22 is threadably connected to the top screw 23 corresponding to the adjusting screw 21 .

[0026] The connecting plate 18 is fixedly connected to the piston rod of the deviation-correcting hydraulic cylinder 17 , and the deviation-correcting hydraulic cylinder 17 is fixedly connected to the base 16 .

[0027] The connecting plate 18 is fixedly connected to the symmetrical U-plates 13 , the symmetrical U-plates 13 are respectively connected to the slide rails 14 , the base 16 is fixedly connected to the symmetrical rails 15 , and the symmetrical slide rails 14 are respectively nested in the corresponding rails 15 .

[0028] A short rod is arranged in the middle of the short rod of the turning frame 5 , and the ends of the short rod are fixedly connected to the guide rollers 3 .

[0029] The left frame 20 is fixedly connected to the alarm device 2 .

[0030] The right frame 12 is fixedly connected to the control panel 8 .

[0031] The left frame 20 is fixedly connected to the flip motor 19, and the output shaft of the flip motor 19 passes through the left frame 20. The output shaft of the flip motor 19 and the flip shaft 4 are driven by a synchronous belt mechanism (not shown in the figure), that is, the output shaft of the flip motor 19 and the flip shaft 4 are respectively fixedly connected to a synchronous wheel, and the synchronous belt is wrapped around the two synchronous wheels. The flip motor 19 rotates, and the flip shaft 4 is driven to rotate through the synchronous belt mechanism, so that the core chuck 1 is swung, which is convenient for replacing raw materials.

[0032] The alarm device 2 , the film pressing actuator cylinder 9 , the deviation correcting actuator hydraulic cylinder 17 , the flipping motor 19 and the regulating cylinder 26 are electrically connected to the control panel 8 respectively.

[0033] The working principle of the unwinding mechanism for polarizer processing provided by the utility model is as follows:

[0034] The winding core clamp 1 close to the alarm device 2 is recorded as station a, and the winding core clamp 1 far from the alarm device 2 is recorded as station b. Station a and station b are used interchangeably. In the initial state, Figure 1 shown.

[0035] When it is necessary to replace the raw materials, first place the raw materials to be connected on the core chuck 1 station a, so that the core chuck 1 fixes the raw material roll, control the flip motor 19 to start, and the flip motor 19 drives the flip shaft 4 to rotate through the synchronous belt mechanism. The flip shaft 4 drives the flip frame 5, the core chuck 1 and the guide roller 3 to rotate clockwise, so that the film material on the station b rotates to the 6 o'clock position, and the film material on the station a rotates to the 12 o'clock position.

[0036] The film material on station b now contacts the film splicing platform pressure roller 3 6. The control panel 8 controls the film splicing pressing execution cylinder 9 to extend, fix the film material on the film splicing platform 10, and make the film splicing platform pressure roller 2 25 press the film material and cut it. Pull the film material on station a and manually pull it onto the film splicing platform 10. The control panel 8 controls the adjustment cylinder 26 to contract, so that the film splicing platform film material fixing rod 11 presses the film material flatly onto the film splicing platform 10; then use tape to connect the two pieces of film material above the film splicing platform 10 together. Finally, the control panel 8 controls the film splicing pressing execution cylinder 9 to contract, so that the adjustment cylinder 26 extends, so that the film splicing platform pressure roller 2 25 and the film splicing platform film material fixing rod 11 are away from the film material, and the film material bypasses the gap adjustment roller 24, connects to the next process, and operates the machine.

[0037] After the machine runs stably, the flip motor 19 can be controlled to rotate clockwise to move the replaced film material (original station a) to the 3 o'clock direction and the used film material roll core (station b) to the 9 o'clock direction for easy disassembly and roll replacement. Due to the existence of the guide roller 3, the film material will not touch the equipment.

[0038] When the film material tension needs to be adjusted, loosen the top screw 23 and rotate the adjusting screw 21. The adjusting screw 21 drives the mounting seat of the gap adjustment roller 24 to move along the guide cylinder 22, so that the gap adjustment roller 24 drives the film material to move and the film material tension is adjusted.

[0039] Compared with the related art, the unwinding mechanism for processing polarizer provided by the utility model has the following beneficial effects:

[0040] The device is provided with an unwinding component to facilitate the replacement of raw materials without stopping the machine, and the guide roller 3 is provided to prevent the film material from hitting the equipment.

[0041] The device is provided with a film pressing execution cylinder 9, etc., so as to facilitate the connection of two film materials together.
