Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention provides a slitting device for producing a release film, such as Figure 1 The figure shows a slitting device for producing a release film. Figure 1 , Figure 3 and Figure 4As shown, it comprises a workbench 1 and a slitting blade 12, the top of the workbench 1 is symmetrically connected to two groups of second vertical plates 29, the two groups of second vertical plates 29 are rotatably connected to the first rotating shaft 5 and the second rotating shaft 8, the top of the workbench 1 is connected to the first vertical plate 11, and the first vertical plate 11 is installed with a motor 3 on the side close to the second vertical plate 29; A first cleaning structure for cleaning the slitting blade 12 is provided above the workbench 1; A transmission mechanism for driving the second rotating shaft 8 to rotate is disposed on the side of the first vertical plate 11 close to the second vertical plate 29; The first cleaning mechanism comprises a cleaning member 20, the outer surface of the first rotating shaft 5 is slidably connected to a plurality of groups of moving seats 4, the outer surface of the moving seats 4 is mounted with slitting blades 12, the bottom of the moving seats 4 is symmetrically connected to four groups of vertical rods 18, the other ends of the four groups of vertical rods 18 are connected to sliding rails 19, the cleaning member 20 is provided with a cleaning surface 21 that fits the slitting blades 12 on one side close to the slitting blades 12, the other side of the cleaning member 20 is connected to an inclined block 13, the inclined block 13 is arranged between two groups of sliding rails 19, and the inclined block 13 is slidably connected to the two groups of sliding rails 19; The cleaning member 20 is provided with a second cleaning mechanism for cleaning the cleaning member 20 on the side close to the slitting blade 12. The present invention can drive the moving seat 4 to move under the action of the motor 3 by providing the first cleaning mechanism and the transmission mechanism, so that the cleaning surface 21 is close to the slitting blade 12 once in a short period of time to clean the outer surface of the slitting blade 12, thereby solving the problem that the outer surface of the slitting blade 12 may be attached with impurities due to the slitting of the release film. If the impurities are not cleaned in time, the release film cut by the slitting blade 12 may be affected by the impurities, resulting in poor quality of the cut release film.

[0021] In certain embodiments, such as Figure 2 As shown, the first cleaning mechanism further includes a horizontal plate 15, the bottoms of the four groups of sliding rails 19 are connected to one end of the first telescopic damping rod 16, the other ends of the four groups of the first telescopic damping rod 16 are all connected to the horizontal plate 15, and the outer surfaces of the four groups of the first telescopic damping rod 16 are all sleeved with a first spring 17. The present invention enables the horizontal plate 15 to move up and down by arranging the first telescopic damping rod 16 to cooperate with the first spring 17.

[0022] In certain embodiments, such as Figure 3 As shown, a corner of the inclined block 13 away from the cleaning member 20 is chamfered, and a movable plate 14 is arranged below the chamfer, and the bottom of the movable plate 14 is connected to the top of the transverse plate 15. The present invention drives the movable plate 14 to move upward by moving the transverse plate 15, and drives the inclined block 13 to move toward the direction close to the slitting blade 12, so that the cleaning surface 21 is closely attached to the outer surface of the slitting blade 12, and the outer surface of the slitting blade 12 is cleaned.

[0023] In certain embodiments, such as Figure 6 As shown, the transmission mechanism includes a first sprocket 26, the output shaft of the motor 3 is connected to the first sprocket 26, the other side of the first sprocket 26 is connected to the first rotating shaft 5, the end of the second rotating shaft 8 close to the second vertical plate 29 is connected to the second sprocket 28, and the outer surfaces of the first sprocket 26 and the second sprocket 28 are provided with a chain 27. The present invention drives the first sprocket 26 to rotate by controlling the motor 3, and drives the first rotating shaft 5 to rotate, drives the slitting blade 12 to rotate, and slits the release film, and drives the second rotating shaft 8 to rotate by setting the chain 27.

[0024] In certain embodiments, such as Figure 6 As shown, the number of gears of the second sprocket 28 is three times the number of gears of the first sprocket 26. The present invention reduces the rotation speed of the second rotating shaft 8 by providing two sets of sprockets with different numbers of gears, and the second rotating shaft 8 does not need to rotate too fast.

[0025] In certain embodiments, such as Figure 1 As shown, the outer surface of the second shaft 8 is slidably connected to multiple groups of convex members 10, and the number of the convex members 10 is the same as the number of the moving base 4. The present invention rotates the second shaft 8 to drive the convex members 10 to rotate, so that the horizontal plate 15 rises and falls once every period of time.

[0026] In certain embodiments, such as Figure 3 and Figure 5 As shown, the second cleaning mechanism includes a scraper 25, the top of the scraper 25 is connected to one end of the second telescopic damping rod 22, the other end of the second telescopic damping rod 22 is connected to the moving seat 4, the outer surface of the second telescopic damping rod 22 is sleeved with a second spring 23, and the scraper 25 is provided with a groove 24 that can fit with the cleaning surface 21 on the side close to the cleaning member 20. The present invention drives the inclined block 13 to move toward the direction close to the slitting blade 12 by the rise of the cross plate 15, so that the second telescopic damping rod 22 shrinks and the second spring 23 is compressed. When the cross plate 15 falls, the inclined block 13 moves away from the slitting blade 12, and the second spring 23 cooperates with the second telescopic damping rod 22 to release elastic potential energy, driving the scraper 25 to move downward, so that the groove 24 is always close to the cleaning surface 21, and the impurities attached to the outer surface of the cleaning surface 21 are removed.

[0027] In certain embodiments, such as Figure 1 As shown, a discharge roller 2 for discharging the release film is arranged on the top of the workbench 1. The discharge roller 2 is a prior art and will not be described in detail here.

[0028] In certain embodiments, such as Figure 1 As shown, a winding roller 9 for winding the release film is arranged on the top of the workbench 1. The winding roller 9 is a prior art and will not be described in detail here.

[0029] In certain embodiments, such as Figure 1 As shown, both sides of the two groups of the first vertical plates 11 are symmetrically connected to the mounting plates 6, and a leveling roller 7 for leveling the release film is arranged between the two corresponding mounting plates 6. The leveling roller 7 is a prior art and will not be described in detail here.

[0030] Working principle: When the present invention is in use, the positions of the movable seat 4 and the convex member 10 are adjusted according to the required width of the release film, and then the release film is stretched straight through the top of the leveling roller 7 by the unwinding roller 2 and the winding roller 9, and then the first rotating shaft 5 is driven to rotate by the control motor 3, and the slitting blade 12 is driven to rotate to cut the release film. While the first rotating shaft 5 rotates, the second rotating shaft 8 is driven to rotate by setting a chain 27, and the convex member 10 is driven to rotate, so that the cross plate 15 rises and falls once every period of time, and the rotation speed of the second rotating shaft 8 is reduced by setting two sets of sprockets with different gear numbers, and the second rotating shaft 8 does not need to rotate. When the cross plate 15 moves too fast, the moving plate 14 moves upward when the cross plate 15 moves upward, and the inclined block 13 moves toward the direction close to the slitting blade 12, so that the cleaning surface 21 is close to the outer surface of the slitting blade 12, and the outer surface of the slitting blade 12 is cleaned. At the same time, the second telescopic damping rod 22 is contracted and the second spring 23 is compressed. When the cross plate 15 descends, the inclined block 13 moves away from the slitting blade 12, and the second spring 23 cooperates with the second telescopic damping rod 22 to release elastic potential energy, driving the scraper 25 to move downward, so that the groove 24 is always close to the cleaning surface 21, and the impurities attached to the outer surface of the cleaning surface 21 are removed.
