Description

Technical Field

[0001] This invention relates to the field of automotive window film processing equipment, and more particularly to a liquid crystal film processing equipment. Background Technology

[0002] Liquid crystal film is a type of film used in car windows. During production, in order to apply the liquid crystal layer to the base layer of the window film, a coating machine is used to apply adhesive, and then hot air is generated in the inner oven to cure and dry it. After drying, the base layer and the functional layer are stacked and then heated and laminated to obtain the liquid crystal film.

[0003] An existing patent application (CN215754581U) describes a raw material conveying device for automotive window film production. This device uses a heater to dry and heat the inside of a power box, the inner cavity of a processing machine on one side of a drive fan, and the surface of the automotive window film on top of the conveyor belt. However, for single-sided drying, the drying temperatures on both sides of the film are different, which can easily lead to incomplete curing of the inner layer adhesive material away from the heat source. Therefore, we propose a liquid crystal film processing equipment to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of incomplete curing of films by heating on one side in the prior art, and to propose a liquid crystal film processing equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liquid crystal film processing device includes a housing, a hot drying assembly, a coating assembly, a laminating assembly, and a re-drying assembly. The housing houses the hot drying assembly and the re-drying assembly, which are arranged in a stacked manner. A coating assembly is located at the inlet of the hot drying assembly, and a laminating assembly is located at the inlet of the re-drying assembly. Each hot drying assembly includes a hot drying chamber, with an upper spray pipe horizontally arranged along the front-to-back direction on the lower inner side of the chamber. A side frame is installed on the front and rear inner walls of the hot drying chamber, and a reversing wheel is installed between the two side frames. A flow guide shell is installed through the top of the hot drying chamber. A drainage sub-pipe is installed at the top of the shell, and a nozzle sub-pipe is installed at the rear end of the upper nozzle; the re-drying assembly includes: a square chamber, a reversing wheel is rotatably installed inside the square chamber, the square chamber is divided into a first chamber and a second chamber by a liquid crystal film coiled on the reversing wheel, a horizontal nozzle is arranged below the first chamber and the second chamber respectively, a suction pipe is arranged above the first chamber and the second chamber, a suction sub-pipe and a horizontal nozzle sub-pipe are arranged at the rear ends of the suction pipe and the horizontal nozzle, respectively, the drainage sub-pipe and the suction sub-pipe are connected in series, and the nozzle sub-pipe and the horizontal nozzle sub-pipe are connected in series;

[0007] To dry the liquid crystal film after coating the substrate with adhesive and stacking functional layers, adhesive is applied to the substrate at the coating assembly location, and then dried with hot air through a hot air drying chamber. Hot air is blown vertically onto the substrate through an upper nozzle to heat the lower layer. The hot air is also drawn in by a guide shell, expelling waste gas while simultaneously causing the hot air to flow upwards over the upper side of the substrate, ensuring uniform drying from both sides. After drying, functional layers are stacked on top of the substrate, and the resulting liquid crystal film enters a square cavity. The liquid crystal film divides the square cavity into the first... The first and second chambers are connected by a horizontal spray pipe that supplies hot air to the lower part of both chambers. As the hot air rises, the suction pipe draws out the exhaust gas and directs the hot air upwards, allowing the liquid crystal film to be dried on both sides by the flowing hot air, ensuring uniform drying. The flow pipe and suction pipe are connected in series, as are the spray pipe and horizontal spray pipe, enabling synchronization of hot air supply and exhaust gas discharge. This ensures a simple pipeline and requires only one heat source and one exhaust gas treatment device, resulting in a compact structure.

[0008] Preferably, multiple nozzle sub-pipes are provided, all of which are arranged in a single row in parallel, and multiple openings are provided at the top of each nozzle sub-pipe;

[0009] The nozzle sub-pipes are arranged in a single row, which can supply hot air to the lower part of the base layer from multiple positions, so that the adhesive layer is evenly dried from the bottom. The nozzle sub-pipes are also equipped with multiple openings at the top to ensure that the air is evenly distributed from front to back.

[0010] Preferably, the diameter of the commutator wheel is greater than the height of the side frame, and a narrow slit for air passage is left between the top of the side frame and the front and rear sidewalls of the liquid crystal film;

[0011] The hot air blown to the lower side of the base layer will rise through the air slits to thoroughly dry the edges of the adhesive layer at both ends of the base layer. The hot air will also flow over the upper side of the base layer so that the upper adhesive layer can also be dried by the hot air, ensuring uniform heating and drying of both layers.

[0012] Preferably, the reversing wheels inside the square cavity are arranged in three layers: upper, middle, and lower. The horizontal spray pipe is located between the middle and lower reversing wheels, and the side wall of the horizontal spray pipe has an air outlet facing the vertical liquid crystal film.

[0013] To ensure uniform drying of the liquid crystal film, the reversing wheels are arranged in three layers (top, middle, and bottom) to repeatedly reverse the liquid crystal film and form a three-layer liquid crystal film. The horizontal spray pipes exhaust air at the bottom vertical position to ensure a low air outlet position and simultaneously dry the left and right sides of the liquid crystal film while exhausting air, thus ensuring uniform drying.

[0014] Preferably, the adhesive application assembly includes an adhesive supply pipe, a dispersing pipe connected in series on the adhesive supply pipe, a manifold with equal spacing in a single row installed through the bottom end of the dispersing pipe, a cover installed at the bottom end of the dispersing pipe, a scraper inside the cover, an arc end provided at the right end of the scraper, an inclined guide surface provided at the top end of the scraper, and partitions with equal spacing installed at the top end of the inclined guide surface.

[0015] The glue supply tube disperses the glue into multiple streams that drip onto the scraper through the dispersion tube and multiple manifolds. The scraper's sloping guide surface, which is higher on the left and lower on the right, causes the glue to flow to the right. Furthermore, the partition can divide the top of the scraper into closely spaced independent channels, ensuring that the dispersed glue can correspond to different base layer positions, thus ensuring uniform material supply. The arc-shaped end can also flatten the glue to form a glue layer.

[0016] Preferably, a symmetrical bracket is installed at the top edge of the scraper, a bracket opening for cooperating with the bracket is opened on the upper left side of the cover, a protrusion is provided on the right side of the bracket, and the cover has slots for cooperating with the protrusion on both sides of the bracket opening, a screw is installed in the middle left side of the scraper, and a screw opening for cooperating with the screw is opened on the left side of the cover.

[0017] The scraper is connected to the cover through a T-shaped bracket, and its position is fixed by a protruding head and a slot. The scraper can be adjusted up and down. After adjustment, the protruding head is engaged in the corresponding slot. After adjustment, it can be locked by a screw and nut, which can realize individual position adjustment of the scraper. The scraper has multiple layers, and glue is supplied above the scrapers except for the top layer, so as to realize the multi-layer coating of glue and further ensure the uniformity of coating.

[0018] Preferably, an adjustment frame is installed on the left side of the cover. The adjustment frame includes support plates installed at the front and rear ends of the cover. A slide is installed on the left end of the support plate. A fixed frame is sleeved on the outside of the slide. An eccentric shaft is rotatably installed on the top of the fixed frame. A lever is installed on the top of the eccentric shaft. A pressure frame is rotatably installed on the right side of the eccentric shaft. The bottom end of the pressure frame overlaps and is disposed on the lower side of the adjustment frame.

[0019] To adjust the scrapers synchronously, the eccentric shaft can be rotated to the left, causing the lower end of the pressure frame to swing to the lower left, thus loosening the adjusting frame. The adjusting frame can then move to the left, causing all the scrapers to move synchronously left and right on the upper part of the fixed frame, improving the synchronization and efficiency of the adjustment.

[0020] Preferably, the overlay assembly includes a tripod, a fixed shaft is rotatably mounted on the lower left corner of the tripod, a connecting shaft is mounted on the lower part of the tripod, a rocker arm is rotatably mounted on the outer side of the connecting shaft, and a movable shaft is rotatably mounted on the bottom end of the rocker arm.

[0021] The tripod can be mounted on a fixed axis, and through a movable axis that can swing with the rocker arm, the functional layers of the base layer and the liquid crystal film can be pressed together for stacking.

[0022] Preferably, the rocker arm has a notch on the side near the tripod, and a spring is installed between the rocker arm and the tripod at the notch;

[0023] The upper part of the rocker arm has a notch, allowing the rocker arm to swing. The elasticity of the spring also helps to tighten the rocker arm and the tripod, making the pressure between the base layer and the functional layer of the liquid crystal film more stable.

[0024] Preferably, a top shaft is installed on the upper part of the tripod, the top shaft is rotatably connected to the outer shell, and a secondary shaft is rotatably installed on the lower right corner of the tripod;

[0025] The tripod swings around the top shaft, allowing it to oscillate. During material feeding, the weight of the tripod and the secondary shaft tightens the base layer and the functional layer of the liquid crystal film, ensuring flattening and smooth adhesion.

[0026] Compared with existing technologies, the advantages of this liquid crystal film processing equipment are:

[0027] 1. Through the setting of the hot drying component, the hot drying component dries the substrate with adhesive in the hot drying chamber. The built-in upward spray pipe dries the hot air from bottom to top. The hot air passes through the air passage slit and flows to the upper part of the substrate to dry the upper adhesive part. It can continuously dry the upper and lower sides. After the substrate and the liquid crystal film functional layer are stacked together, the stacked liquid crystal film will be reversed by the reversing wheel to divide the square chamber into the first chamber and the second chamber. The horizontal spray pipe enters from the bottom of the first chamber and the second chamber, and the suction pipe draws out the air above the first chamber and the second chamber, which will cause the hot air below to rise and simultaneously heat the two sides of the liquid crystal film, improving the drying uniformity and efficiency.

[0028] 2. Through the setting of the glue application assembly, the dispersing tube supplies glue to the base layer through multiple manifolds, guides the glue to the base layer position through the inclined guide surface of the scraper, and flattens it through the arc end. There are multiple dispersing tubes arranged at the top and bottom. The scraper and the cover are connected by a bracket, and the distance between the scraper and the base layer can be adjusted individually, so that the gap between multiple scrapers and the base layer gradually increases. This allows for multi-layer and multi-stage application of glue, improving the uniformity of the coating. The scraper can also be moved to the right and away from the base layer simultaneously for synchronous adjustment, improving the efficiency of adjustment. After adjustment, the eccentric shaft can be moved to the right, so that the right end of the adjustment frame is pushed to the upper right. The adjustment frame and the slide are fixed by the pressure frame to ensure the stability of the scraper position during operation.

[0029] 3. Through the setting of the stacking components, the base layer and functional layer after adhesive application are pressed and adhered at the fixed axis and moving axis positions to form an integral liquid crystal film. During the pressing process, a spring is used to tighten the film, ensuring its stability. Liquid crystal films of different thicknesses can be used to ensure the flexibility and adaptability of the pressing function. The tripod can swing with the top axis. During feeding, the functional layer is tensioned and flattened by the secondary axis, ensuring the flatness of the adhered liquid crystal film. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Example 1

The hot drying assembly 2 includes a hot drying chamber 21, an upper spray pipe 22 horizontally arranged along the front-back direction on the lower inner side of the hot drying chamber 21, a side frame 24 installed on the front and rear inner walls of the hot drying chamber 21 respectively, a reversing wheel 11 installed between the two side frames 24, and a flow guide shell 23 penetratingly installed at the top of the hot drying chamber 21. A flow guide secondary pipe is installed at the top of the flow guide shell 23. 231, a nozzle sub-pipe 221 is installed at the rear end of the upper nozzle 22; the re-drying assembly 5 includes: a square chamber, a reversing wheel 11 is rotatably installed inside the square chamber, the square chamber is divided into a first chamber 511 and a second chamber 512 by a liquid crystal film coiled on the reversing wheel 11, a horizontal nozzle 52 is arranged below the first chamber 511 and the second chamber 512 respectively, a suction pipe 54 is arranged above the first chamber 511 and the second chamber 512, a suction sub-pipe 541 and a horizontal nozzle sub-pipe 521 are arranged at the rear ends of the suction pipe 54 and the horizontal nozzle 52 respectively, the drainage sub-pipe 231 and the suction sub-pipe 541 are connected in series, and the nozzle sub-pipe 221 and the horizontal nozzle sub-pipe 521 are connected in series.

[0044] To dry the liquid crystal film after coating the substrate with adhesive and stacking the functional layers, adhesive is applied to the substrate at the coating assembly 3, and then dried with hot air through the hot drying chamber 21. The hot air is blown vertically onto the substrate through the upper spray pipe 22 to heat the lower layer. The hot air is also drawn in by the guide shell 23, which discharges the exhaust gas and causes the hot air to flow upward over the upper side of the substrate, ensuring that the substrate is dried evenly from both sides. After drying, the functional layers are stacked on the stacking assembly 4, and the resulting liquid crystal film enters the square cavity. The liquid crystal film divides the square cavity into a first cavity 511 and a second cavity. 512, the horizontal spray pipe 52 provides hot air to the lower part of the first chamber 511 and the second chamber 512. As the hot air rises, the suction pipe 54 draws the exhaust gas out and directs the hot air upward, so that the liquid crystal film is dried on both sides by the flowing hot air, ensuring uniform drying. The diversion sub-pipe 231 and the suction sub-pipe 541 are connected in series, and the spray pipe sub-pipe 221 and the horizontal spray sub-pipe 521 are connected in series, which can realize the synchronization of hot air supply and exhaust gas discharge, ensure the simplicity of the pipeline, and only require one heat source and one exhaust gas treatment device, making the structure compact.
