Description

Technical Field

[0001] This utility model relates to the technical field of silicone protective film coating machines, and in particular to a silicone protective film coating machine. Background Technology

[0002] Silicone screen protectors are primarily used to protect electronic products. The mainstream silicone screen protector is the PET silicone screen protector, which is suitable for protecting the surfaces of mobile phones, computers, various screen displays, mirrors, glass, and other surfaces, providing protection against scratches, dust, and radiation.

[0003] A search revealed Chinese Patent Publication No. CN223027566U, which discloses a silicone protective film coating machine, comprising a coating machine upright plate, a lower coating cover, a lower drying oven, an upper drying oven, and an upper coating cover. The lower and upper coating covers are respectively fixed to the outer wall of one side of the coating machine upright plate. In use, this technical solution sprays the coating onto the silicone protective film through a spray pipe and then spreads the coating evenly through coating rollers. However, the coating rollers on the upper and lower sides of the silicone protective film cannot be adjusted during use, making it impossible to adjust the coating gap according to the thickness and other specifications of the silicone protective film in actual production. This results in the equipment being difficult to adapt to the production needs of different types of silicone protective films, thus limiting its applicability. Therefore, a silicone protective film coating machine is proposed to solve the above-mentioned problems. Utility Model Content

[0029] Example

[0030] like Figures 1-6 As shown, this utility model provides a technical solution: a silicone protective film coating machine, including a base 1 and a lifting frame 2. The base 1 serves as the basic load-bearing structure of the equipment, and the lifting frame 2 is located above the base 1. The lifting frame 2 has a U-shaped structure design, and two support frames 3 are fixedly installed on the top of the base 1 as the support structure of the equipment.

[0031] An adjustment mechanism 4, extending outward and fixedly connected to the lifting frame 2, is movably installed inside the rear support frame 3. The adjustment mechanism 4 includes a lifting block 41, which is fixedly installed on the rear side of the bottom of the lifting frame 2 and extends into the interior of the rear support frame 3. A groove 411 adapted to the lifting block 41 is provided inside the rear support frame 3. An adjustment screw 42 rotatably connected to the interior of the support frame 3 is rotatably installed on the bottom of the lifting block 41. An adjustment screw 42 located on both sides of the adjustment screw 42 and extending into the support frame 3 is fixedly installed on the bottom of the lifting block 41. The guide column 43 inside the frame 3 restricts the lifting block 41 to move only in the vertical direction, avoiding deviation caused by the rotation of the lead screw and ensuring the stability of the lifting trajectory. A control motor 44 is fixedly installed on the rear side of the rear support frame 3. The output shaft of the control motor 44 and the outer side of the adjusting lead screw 42 are both fixedly installed with bevel gears 45. The two bevel gears 45 mesh with each other, and the rotational motion of the output shaft of the control motor 44 is converted into linear motion, driving the lifting block 41 and the lifting frame 2 to lift and lower, so as to achieve precise adjustment of the gap between the coating roller 54 and the film material.

[0032] A drying and coating assembly 5 is fixedly installed between the lifting frame 2 and the two support frames 3 on opposite sides. The drying and coating assembly 5 includes a drying chamber 51 and a coating chamber 52. There are two drying chambers 51 and two coating chambers 52, which are respectively fixedly installed on the inner side of the lifting frame 2 and between the opposite sides of the two support frames 3. A heating rod 53 is fixedly installed on the inner side of the drying chamber 51. A coating roller 54 is rotatably installed inside the coating chamber 52. A spray pipe 55 is fixedly installed inside the coating chamber 52. A connecting pipe 551 that extends through to the outside of the coating chamber 52 is connected to the outside of the spray pipe 55. The drying chamber 51 and coating chamber 52, as well as their internal structures, all adopt existing technologies. This silicone protective film coating machine, through the coordinated action of the control motor 44, bevel gear 45, adjusting screw 42, and guide column 43 in the adjustment mechanism 4, allows the lifting frame 2 to be precisely raised and lowered. Combined with the synchronous movement of the coating chamber 52 and drying chamber 51 in the drying and coating assembly 5, the gap between the coating rollers 54 on the upper and lower sides and the film material can be flexibly adjusted, effectively adapting to the production needs of silicone protective films of different thicknesses and solving the problem of poor applicability caused by the fixed coating rollers in traditional equipment.

[0033] A traction mechanism 6 is movably installed between the lifting frame 2 and the two support frames 3 on opposite sides, located outside the drying and coating assembly 5. The traction mechanism 6 includes guide rollers 61, idler rollers 62, and traction rollers 63, with two of each. These rollers are rotatably installed on the inner side of the lifting frame 2 and between the opposite sides of the two support frames 3, respectively. The guide rollers 61, idler rollers 62, and traction rollers 63 are located on the outer sides of the drying chamber 51 and the coating chamber 52. Protective covers 64 are fixedly installed on the front side of the front support frame 3 and the outer side of the lifting frame 2. One end of the guide roller 61, the idler roller 62, and the traction roller 63 all extend into the interior of the protective cover 64 and are connected by a transmission belt. A drive motor 65 is fixedly installed on the front side of the protective cover 64. The output shaft of the drive motor 65 is fixedly connected to the traction roller 63. Transmission belts and transmission wheels are installed between adjacent rollers, so that the output shaft of the drive motor 65 can drive the traction roller 63, the guide roller 61, and the idler roller 62. The synchronous transmission of power is achieved through the cooperation of the transmission belt and the transmission wheel, ensuring that each roller works in coordination and improving the stability and consistency of the film material conveying.

[0034] The drying and coating assembly 5 has a movably mounted scraper assembly 7 extending to its outer side. The scraper assembly 7 includes an insert block 71, which is embedded in the coating box 52 and extends to its front side. A magnetic block 711 is fixedly connected to one end of the insert block 71 on the outer side of the coating box 52 to enhance the positional stability of the insert block 71 and prevent it from loosening due to vibration. The magnetic block 711 is in contact with the lifting frame 2 and the support frame 3. A mounting block 72 extending to its top is movably mounted inside the insert block 71. A scraper 73 that is in contact with the coating roller 54 is fixedly mounted on one end of the mounting block 72 on the outer side of the insert block 71 for applying the coating. The coating on the surface of roller 54 is evenly scraped. The front side of the embedded block 71 is threaded with a limiting stud 74 extending into the mounting block 72. The front side of the limiting stud 74 is fixedly connected to a rotating knob 741. This silicone protective film coating machine, by setting the design of the embedded block 71 in the scraper assembly 7 to be embedded in the coating box 52, combined with the detachable structure of the mounting block 72 and the locking function of the limiting stud 74, can not only make the scraper 73 evenly scrape the coating on the outside of the coating roller 54, but also facilitate the cleaning of the scraper 73 or the replacement of worn parts when the machine is stopped. The setting of the magnetic block 711 enhances the positioning stability of the embedded block 71, further ensuring the continuity of coating accuracy.

[0035] The working process of this utility model:

[0036] Step 1: Based on the thickness of the silicone protective film or the coating process requirements, start the control motor 44 in the adjustment mechanism 4. Its output shaft drives the adjustment screw 42 to rotate through the meshing bevel gear 45. The lifting block 41 moves up and down along the guide column 43 with the spiral movement of the adjustment screw 42 (the guide column 43 ensures the stability of the lifting trajectory), thereby pushing the lifting frame 2 to lift up and down as a whole until the gap between the upper coating roller 54 and the support roller 62 and guide roller 61 of the traction mechanism 6 is adapted to the current film thickness, and the initial positioning of the equipment is completed.

[0037] Step 2: The drive motor 65 is started by controlling the output shaft to directly drive the traction roller 63 to rotate. The traction roller 63 drives the guide roller 61 through the transmission belt in the protective cover 64. The guide roller 61 drives the idler roller 62 through the transmission belt, forming a continuous traction force. After the silicone protective film enters from the feed end of the equipment, it is guided by the guide roller 61, lifted by the idler roller 62, and pulled by the traction roller 63 in sequence. It passes through the coating box 52 and the drying box 51 according to the set path and is finally output from the winding end.

[0038] Step 3: When the membrane material enters the two coating boxes 52 on opposite sides, the spray pipe 55 is connected to the glue supply device through the connecting pipe 551 to spray the coating evenly on the surface of the membrane material; and the coating roller 54 rotates to spread the coating evenly on the membrane material. The coated membrane material enters the drying box 51, where the heating rod 53 is energized and heats up. The membrane material is dried by heat radiation or hot air (the specific method depends on the structural design of the drying box 51, using known structural components in the prior art), so that the coating material is cured into a film.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
