Description

Technical Field

[0001] The present invention relates to the technical field of flexible printing plate manufacturing, and more specifically, to a cleaning and sealing integrated device for a material discharging port of an alignment film printing plate manufacturing device. Background Art

[0002] Alignment film printing is a type of relief printing process that uses a flexible photosensitive resin plate and transfers ink through an anilox roller. The printing part of the alignment film printing plate is raised. During printing, the anilox roller evenly applies a certain thickness of ink layer to the part to be printed on the plate. Then, under the pressure of the embossing roller, the ink layer of the part to be printed is transferred to the surface of the substrate to form a layer of alignment film. The flexible photosensitive resin plate involved in this application is mainly used in the liquid crystal panel display industry. The alignment film here refers to the PI alignment film that provides a pre-tilt angle for the liquid crystal.

[0003] At present, the main raw material of the equipment for producing printing plates is photosensitive resin. The liquid resin is evenly coated on the platform through a pressure vessel. After solidification, the original plate material of the printing plate is obtained. After each resin coating, two operators are required to clean the discharge port with solvent and then seal the discharge port with tape. The discharge port is a 0.7mm*2.5m blade. If the discharge port is not sealed with tape in time after cleaning, new resin will overflow. At the same time, it is necessary to ensure that the discharge port is clean and no air can enter, otherwise it will affect the next production.

[0021] like Figures 1 to 3 As shown, the present invention provides an integrated cleaning and sealing device for a discharging port of an alignment film printing plate manufacturing device, comprising a box body 2 slidably arranged along the length direction of a discharging blade 1, a sealing tape 3 is arranged in the box body 2, and a central axis thereof is perpendicular to the length direction of the discharging blade 1 so that the tape extends along the length direction of the discharging blade 1 and seals the discharging blade 1, an upper platform 4 is arranged in parallel directly above the box body 2, a rubber wheel 5, a placement groove 6 and a scraper 7 are arranged on the upper platform 4 in sequence along the moving direction of the box body 2, the top surfaces of the rubber wheel 5, the placement groove 6 and the scraper 7 all have concave grooves to match the discharging blade 1, the rubber wheel 5 is located behind the movement of the sealing tape 3, the tape of the sealing tape 3 is wound around the rubber wheel 5 and extends horizontally to the rear of the moving direction of the box body 2, the adhesive surface of the tape faces the discharging blade 1, a non-woven fabric is arranged in the placement groove 6 for cleaning the discharging blade 1, and the scraper 7 is also used to clean the discharging blade 1.

[0022] The present application manufactures a box body 2, inside which a sealing tape 3 can be placed. At the same time, an upper platform 4 is manufactured, on which a Teflon scraper 7 with a groove, a dust-free cloth placement groove 6 with a groove, and a rubber wheel 5 with a groove are sequentially arranged. The upper platform 4 is connected to the box body 2 below by maintaining the slide groove 8 and the telescopic cylinder 9, and the box body 2 can slide smoothly in the slideway 17, and a laser generator 15 is arranged at both ends of the slideway 17. When in use, the sealing box body 2 is aligned with the material discharging blade 1 through the laser generator 15, the dust-free cloth is placed in the middle placement groove 6, one end of the tape is fixed to one end of the material discharging blade 1, the cylinder 9 is raised to lift the upper platform 4 to contact the material discharging blade 1, and the main body of the device is slid to the right at a uniform speed, so that the sealing tape 3 can be used to timely and accurately seal the material discharging blade 1 while cleaning the material discharging blade 1. Through the above device, it can be operated by one person and the operation time can be reduced, the success rate of sealing can be improved, and the production capacity can be increased.

[0023] In another technical solution, the upper platform 4 is supported by a pair of retaining grooves 8 on the top of the box body 2, and the upper platform 4 is vertically slidably connected to the pair of retaining grooves 8. The pair of retaining grooves 8 are symmetrically arranged on both sides of the box body 2. A pair of cylinders 9 are also symmetrically arranged on both sides of the box body 2. A buffer spring 10 is fixedly arranged on the top of the telescopic rod. The buffer spring 10 extends out of the box body 2 and is tightly supported on the bottom surface of the upper platform 4.

[0024] The upper platform 4 is used to install various structures for cleaning and sealing. In the initial state, i.e. when the device is installed, the cylinder 9 is retracted, and there is a certain space between the upper platform 4 and the material discharging blade 1, which is convenient for the installation and position adjustment of the device. After the installation is completed, the cylinder 9 is extended to drive the upper platform 4 to work closely against the material discharging blade 1. The upper platform 4 realizes vertical sliding through a pair of retaining slide grooves 8 during the up and down movement. A buffer spring 10 is arranged on the top of the cylinder 9. On the one hand, it allows each cleaning and sealing structure on the upper platform 4 to have a certain buffer space and method with the material discharging blade 1. On the other hand, the buffer spring 10 can also be used to make each cleaning and sealing structure on the upper platform 4 closely contact with the material discharging blade 1 and have a certain pressure, thereby ensuring the cleaning effect and at the same time ensuring the tight sealing of the material discharging blade 1 by the adhesive tape, and no separate clamping mechanism is required after sealing.

[0025] In another technical solution, Figure 4 As shown, the top of the box body 2 is provided with a concave channel, which is arranged along a length direction perpendicular to the discharging blade 1, the bottom of the retaining slide groove 8 extends into the channel of the box body 2 and is slidably arranged along the channel, and the side of the box body 2 is provided with an internal threaded through hole along the channel direction, and the internal thread is matched with a screw 12, the inner end of the screw 12 extends to be rotatably connected to the bottom of the retaining slide groove 8 through a bearing, and the outer end of the screw 12 extends to the outside of the box body 2 and is provided with a rotating handle 11.

[0026] In order to ensure accurate cleaning and sealing of the material discharging blade 1, after the box body 2 is installed, it is necessary to align the positions of the structures on the upper platform 4 so that the positions of the rubber wheel 5, the placement groove 6 and the scraper 7 exactly correspond to the material discharging blade 1, which is achieved by setting structures such as channels. The screw 12 is driven to rotate by rotating the handle 11, and the screw 12 drives the slide 8 to move back and forth along the channel, thereby adjusting the upper platform 4 in the slide 8 to drive the rubber wheel 5, the placement groove 6 and the scraper 7 to a suitable position exactly corresponding to the material discharging blade 1.

[0027] In another technical solution, the internal threaded through hole extends outward and is fixedly connected with a sleeve 13, which is a transparent structure, and the sleeve 13 is marked with scales, and the screw 12 is marked with red marking lines 14. The positions of the red marking lines 14 on a pair of screws 12 corresponding to a pair of retaining grooves 8 are exactly the same, and the scale markings on a pair of sleeves 13 corresponding to a pair of screws 12 are also exactly the same.

[0028] In order to ensure that a pair of slide grooves 8 are adjusted to the same position of the upper platform 4, so that the upper platform 4 moves stably and smoothly, a transparent sleeve 13 with scale lines is provided, and a striking red marking line 14 is correspondingly provided on the screw 12. The requirement of synchronous adjustment can be met by only observing that the positions of the red marking lines 14 on the pair of screws 12 on the sleeve 13 are always consistent.

[0029] In another technical solution, laser generators 15 for alignment are provided on both outer sides of the box body 2 in the moving direction, which are used to monitor the position of the rubber wheel 5, the placement groove 6 and the scraper 7 on the box body 2 and align them with the position of the discharging blade 1.

[0030] In another technical solution, the box body 2 is arranged on an equipment platform 16, on which a slide 17 is arranged. The box body 2 is slidably arranged on the slide 17 and is moved by manual pushing or by setting a driving mechanism, such as a winch.

[0031] In another technical solution, Figure 5 As shown, the end of the slide 17 located at the initial end of the discharging blade 1 to be sealed is provided with a pair of supporting legs 18, which is a telescopic structure, and the tops of the pair of supporting legs 18 are provided with U-shaped openings, and a roller 19 is provided between the pair of supporting legs 18, and its two ends are respectively engaged in the pair of U-shaped openings, and the ends of the roller 19 are provided with through holes, and the pair of supporting legs 18 are also provided with a pair of through holes, which correspond exactly to the through holes on the roller 19 and are fixedly connected as a whole by inserting a plug rod 20, and a tape is wrapped around the roller 19 to fix the tape to the initial end of the discharging opening to be sealed.

[0032] If the end of the tape is directly attached to the material discharging blade 1, it may be detached, etc., and a pair of supporting legs 18 and a roller 19 are provided for fixing and positioning. The pair of supporting legs 18 can be retracted to achieve vertical position adjustment during and after installation, that is, position adjustment with respect to the material discharging blade 1. First, a portion of the tape is wound around the roller 19 to achieve connection with the tape, and then the roller 19 is placed in the U-shaped opening and the rod 20 is inserted into the fixed roller 19 to achieve the fixation of the position of the roller 19, that is, the fixation of the tape end.

[0033] In another technical solution, Figure 6 As shown, the sealing tape 3 is rotatably sleeved on the fixed shaft 21, or the sealing tape 3 is rotatably connected to the fixed shaft 21 by setting a bearing, and both ends of the fixed shaft 21 are connected to the side walls of the box body 2. The fixed shaft 21 and the winding ring of the sealing tape 3 are both provided with concave bayonet sockets, and the same L-shaped plug-in 22 is inserted into them for limiting.

[0034] The sealing tape 3 is set to rotate freely, which is not conducive to tightening and sealing the material discharging opening. During installation, after the end is wound by the roller 19, the position of the sealing tape 3 is fixed and it is not allowed to rotate. This is achieved through the plug-in 22. The plug-in 22 has a certain elasticity and can be inserted into the two L-shaped bayonet slots to fix the sealing tape 3. Then, other structures of the device are installed and the position is adjusted. After the adjustment is completed, the plug-in 22 is pulled out during the movement, and the sealing tape 3 can be rotated again. An opening is set on the front of the box body 2 to operate the plug-in 22.
