[0031] Embodiment 1:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a fixed-point slitting device for processing an optical film of the present invention comprises a supporting platform 1, on which a conveying roller 2 for conveying an optical film is arranged, on which a supporting assembly 3 is arranged, on which a toggle assembly 4 is arranged, on which a sliding assembly 5 is arranged, on which a slitting assembly 6 is arranged, and the toggle assembly 4 is used to toggle the slitting assembly 6 to adjust the width of the slitting assembly 6, on which an adjusting assembly 7 is arranged, and on which an output end of the adjusting assembly 7 is arranged a connecting assembly 8 connected to the slitting assembly 6, between which a clamping assembly 9 is arranged, and on which an inflatable assembly 10 connected to the supporting assembly 3 and the adjusting assembly 7 is arranged; wherein, when the clamping assembly 9 is separated from the connecting assembly 8, the toggle assembly 4 drives the slitting assembly 6 to move to a reasonable position, and the slitting assembly 6 forms a primary width adjustment; when the clamping assembly 9 is clamped with the connecting assembly 8, one or more slitting assemblies 6 retreat, so that the slitting assembly 6 forms a secondary width adjustment, thereby realizing arbitrary width adjustment.

[0033] Working principle: When the present invention is slitting an optical film, the optical film is wound on a conveying roller 2 for transmission, and the optical film is slid by a slitting component 6 to form an optical film of a certain width, and the adjusting component 7 is connected to the slitting component 6 by a connecting component 8, and the clamping component 9 is separated from the connecting component 8, and the adjusting component 7 is adjusted to a reasonable position by an inflatable component 10, so as to force the connecting component 8 and the slitting component 6 to move to a reasonable position. When adjusting the slitting width of the slitting component 6, the supporting component 3 is adjusted to a reasonable position by an inflatable component 10, so that the supporting component 3 moves up and down, so that the supporting component 3 forces the toggle component 4 to move, so that the toggle component 4 toggle the slitting component 6, and when sliding Under the action of the component 5, the slitting component 6 is forced to move to a reasonable position until the slitting component 6 moves to the required width, thereby forming a first-level width adjustment. During slitting, the conveying roller 2 conveys the optical film, forcing the slitting component 6 to slit the optical film, completing the first-level slitting action; when the slitting component 6 needs to be replaced, the inflatable component 10 forces the adjusting component 7 to move to the maximum position, so that the adjusting component 7 drives the connecting component 8 and the slitting component 6 to move to the replacement position, so that the slitting component 6 is exposed, and the staff replaces the corresponding slitting component 6; on the basis of the first-level width adjustment, under the action of the inflatable component 10, the supporting component 3 is forced to move upward to a reasonable height, at which time the toggle component 4 will drive the slitting component The slitting assembly 6 moves to a reasonable position, so that the slitting assembly 6 moves to the required width position, and the spaced slitting assembly 6 is used to determine the larger width requirement. Before the slitting assembly 6 moves to the reasonable width position, one or more connecting assemblies 8 are forced to separate, so that the adjusting assembly 7 is separated from the slitting assembly 6, and the connecting assembly 8 is connected to the snap-on assembly 9 to form a whole. The supporting assembly 3 continues to move upward. When the other slitting assemblies 6 move to the reasonable width position, the toggle assembly 4 drives the snap-on assembly 9 to move upward. Since the connecting assembly 8 is separated, the snap-on assembly 9 drives the connecting assembly 8 to move upward, forcing one or more slitting assemblies 6 to move upward, forcing one or more slitting assemblies 6 to be connected to the optical thin film. The film is detached and the optical film cannot be cut, while the other cutting components 6 move to the required width position, thereby forming a two-level width adjustment, and the adjustment between the cutting components 6 can achieve an arbitrary width adjustment effect; in summary, the present application is a fixed-point cutting device for optical film processing, which can use its own components to realize automatic adjustment of the width of the cutting component 6, without the need to frequently replace the cutting component 6, which is conducive to the cutting of optical films, can meet the different width requirements of optical films, can achieve arbitrary width adjustment requirements, and achieve multi-level adjustment effects during the width adjustment process, thereby improving the device's own adjustment function, and can realize the maintenance and replacement of the cutting component 6, thereby improving the adaptability of the device and improving the market competitiveness of the enterprise.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a fixed-point slitting device for optical film processing of the present invention, the inflation component 10 includes an inflation pump 1001 installed on a support frame 501, an inflation tube 1002 is provided at the output end of the inflation pump 1001, an air distribution tube 1003 connected to the regulating cylinder 701 is provided on the inflation tube 1002, a connecting tube 1004 connected to the supporting cylinder 301 is provided on the inflation tube 1002, and an electromagnetic valve 1005 is installed on both the air distribution tube 1003 and the connecting tube 1004.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a fixed-point slitting device for optical film processing of the present invention is provided, a support frame 501 is provided with a detection component 11 adapted to the connecting rod 902, the detection component 11 includes an outer rod 1101 arranged on the support frame 501, an inner rod 1102 adapted to the outer rod 1101 is inserted into the outer rod 1101, a detection rod 1103 adapted to the connecting rod 902 is provided on the inner rod 1102, and a detection spring 1104 sleeved on the outer ring of the inner rod 1102 is provided between the outer rod 1101 and the detection rod 1103.

[0044] Working principle: When the optical film is cut, the optical film is wound on the conveying roller 2 for conveying, and the optical film is cut by the slitting knife 604 to form an optical film of a certain width, and the cut optical film is rolled up by the rolling device;

[0045] During cutting, the first electromagnet ring 802 is energized to force the first electromagnet ring 802 to generate magnetism to generate attraction to the magnet rod 803, thereby forming a connection with the magnet rod 803, and the second electromagnet ring 903 is not energized to prevent the second electromagnet ring 903 from acting on the magnet rod 803. At this time, the adjusting rod 703, the connecting plate 801, the first electromagnet ring 802, the magnet rod 803 and the sliding plate 602 are integrated. Since the second electromagnet ring 903 does not act on the magnet rod 803, the magnet rod 803 can slide in the second electromagnet ring 903.

[0046] Start the air pump 1001 and the corresponding solenoid valve 1005. The air pump 1001 inflates the regulating cylinder 701 through the air pipe 1002 and the air distribution pipe 1003, forcing the regulating piston 702 to move to a reasonable position, so that the regulating piston 702 drives the regulating rod 703 to move to a reasonable position, the regulating rod 703 drives the connecting plate 801 to move to a reasonable position, the connecting plate 801 drives the electromagnet ring 802 and the magnet rod 803 to move, the magnet rod 803 drives the sliding plate 602 and the mounting plate 603 to move to a reasonable position in the sleeve 601, and the mounting plate 603 drives the slitting knife 604 to move to a reasonable height until all the slitting knives 604 can slit the optical film;

[0047] When adjusting the slitting width of the slitting knife 604, start the air pump 1001 and the corresponding electromagnetic valve 1005, and the air pump 1001 inflates the support cylinder 301 through the air pipe 1002 and the connecting pipe 1004. Under the action of the support spring 304, the support piston 302 moves to drive the support rod 303 to move. When the support rod 303 moves up and down, the support rod 303 is forced to drive the toggle plate 403 to move. Under the action of the guide groove 404, the toggle plate 403 is forced to drive the toggle wheel 402 and the toggle rod 401 to move, so that the toggle rod 401 drives the sleeve 601 and the sliding block 503 to move horizontally along the guide rod 502. The movement causes the slitting knife 604 to move synchronously to a reasonable position until the slitting knife 604 moves to the required width, thereby forming a first-level width adjustment and completing the width adjustment of the slitting knife 604. During slitting, the conveying roller 2 conveys the optical film, forcing the slitting knife 604 to slit the optical film, completing a first-level slitting action; wherein, during the horizontal movement of the sliding block 503 and the sleeve 601, the sliding block 503 drives the adjusting component 7 and the connecting component 8 to move horizontally, and the sleeve 601 drives the slitting component 6 to move horizontally, at which time the second electromagnet ring 903 slides on the magnet rod 803, and at the same time, the T-shaped slider 901 slides on the toggle plate 403;

[0048] When the slitting knife 604 needs to be replaced and repaired, the air pump 1001 is started to force the adjusting piston 702 to move to the maximum position, so that the adjusting rod 703 drives the connecting plate 801, the electromagnet ring 802, the magnet rod 803, the sliding plate 602, the mounting plate 603 and the slitting knife 604 to move to the replacement position, forcing the slitting knife 604 to be exposed from the sleeve 601, and the staff uses tools to disassemble the screws and nuts and replace the corresponding slitting knife 604;

[0049] On the basis of the first-level width adjustment, the air pump 1001 and the corresponding electromagnetic valve 1005 are started, and the air pump 1001 inflates the support cylinder 301 through the air pipe 1002 and the connecting pipe 1004, forcing the support rod 303 to drive the toggle plate 403 to move to a reasonable position, forcing the toggle rod 401 to move and drive the sleeve 601 to move to a reasonable position, so that the slitting knife 604 moves to the required width position, and the spaced slitting knives 604 are used to determine the larger width requirement. For example: for example, during the first-level adjustment, the first, second and third slitting knives 604 are used, and during the second-level adjustment, the first and third slitting knives are used for slitting, thereby expanding the slitting width;

[0050] Before the slitting knife 604 moves to the required width position, the power supply of one or more electromagnet rings 802 is disconnected, forcing the electromagnet ring 802 to separate from the magnet rod 803. At this time, the connecting plate 801 is separated from the magnet rod 803, and the magnet rod 803 slides in the electromagnet ring 1 802. At the same time, the power supply of one or more electromagnet rings 903 is turned on, so that the magnet rod 803 and the electromagnet ring 903 are integrated, and the support rod 303 continues to move upward. When the other slitting knives 604 move to the reasonable width position, the toggle plate 403 drives the T-shaped slider 901, the connecting rod 902 and the electromagnet ring 903 to move upward, forcing the slitting knife 604 to move horizontally. During the movement, the second electromagnet ring 903 drives the magnet rod 803 to slide upward on the first electromagnet ring 802. Under the action of the mounting plate 603 and the sliding plate 602, one or more of the slitting knives 604 move upward, forcing one or more of the slitting knives 604 to separate from the optical film, so that the slitting knives 604 cannot slit the optical film. When the other slitting knives 604 move to the required width position, one or more of the slitting knives 604 separate from the optical film, and the other slitting knives 604 move to the required width position to slit the optical film, thereby forming a secondary width adjustment. By adjusting the multiple slitting knives 604, the adjustment effect of any width can be achieved.

[0051] During the retreat process of the slitting knife 604, that is, when the slitting knife 604 is forced to retreat to the original position at the same height, since one or more slitting knives 604 move upward for a certain distance, when retreating, when the other slitting knives 604 move to the original position, one or more slitting knives 604 have not yet moved to the original position, when the other connecting rods 902 move and contact with the detection rod 1103, the action of the support component 3 is stopped, the power supply of the electromagnet ring 2 903 is disconnected, and the power supply of the electromagnet ring 1 802 is turned on, forcing the electromagnet ring 1 802 to be connected to the magnet rod 803 again to form a whole, and the electromagnet is adjusted by the adjustment component 7. The positions of ring 1 802, magnet rod 803, sliding plate 602, mounting plate 603 and slitting knife 604 force the slitting knife 604 to move to the original position at the same height as other slitting knives 604 to complete the retraction action; when the toggle plate 403 drives the connecting rod 902 to move excessively, the connecting rod 902 will press the detection rod 1103. Under the action of the detection spring 1104, the inner rod 1102 slides in the outer rod 1101, thereby achieving a protective effect, preventing the electromagnet ring 2 903 from driving the magnet rod 803 to move excessively, preventing the slitting knife 604 from moving excessively, and improving the protective effect on the slitting knife 604.
