AI Technical Summary
When the amount of paint discharged from the existing coating equipment is large, the paint tends to overflow from the discharge part of the coating roller, resulting in uneven application of the fireproof coating and contamination of the equipment by the overflowing paint.
A coating device was designed, comprising components such as a housing, a coating roller, a motor, a deflecting roller, a scraper, and gears. By synchronously rotating the coating roller and the deflecting roller, and with the scraper removing excess coating, uniform coating is achieved. The distance between the scraper and the fire blanket is adjusted by adjusting the screw to ensure uniform coating thickness.
This method achieves uniform coating of the paint on the surface of the fire blanket, avoiding uneven coating that could affect the performance of the fire blanket, and recovers excess paint, thereby improving the practicality of the device and the uniformity of the fireproof coating.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Depend on Figure 1 , Figure 2 and Figure 3 This invention discloses a coating device for a fiberglass fire blanket. A liquid storage tank is provided at the top of the outer casing 100. A coating roller 101 is rotatably connected to the front and rear side walls of the inner cavity of the liquid storage tank, facilitating the application of coating material onto the fire blanket. A motor 102 is fixedly connected to the front side wall of the outer casing 100, driving the coating roller 101 to rotate. The output end of the motor 102 is connected to the front end of the coating roller 101. A support frame 103 is fixedly connected to the top of the outer casing 100, supporting a turning roller 104. Turning rollers 104 are rotatably connected to the front and rear side walls of the inner cavity of the support frame 103, facilitating turning and conveying. The fire blanket is conveyed with the coating roller facing upwards. The deflecting roller 104 is located to the upper right of the coating roller 101, allowing the fire blanket to adhere to the surface of the coating roller 101 for coating. A fixing frame 105 is fixedly connected to the top of the outer shell 100, which facilitates the support of the connecting frame 106. The connecting frame 106 is installed on the top of the fixing frame 105, which facilitates the support of the scraper 107. The scraper 107 is fixedly connected to the left end of the connecting frame 106, which facilitates the scraping of excess coating on the surface of the fire blanket. The left side wall of the scraper 107 is arc-shaped to facilitate the falling and recovery of coating. The scraper 107 is located to the right of the deflecting roller 104.
[0021] In this embodiment: the coating material is injected into the inner cavity of the storage tank, so that the lower side of the outer wall of the coating roller 101 is immersed in the outer wall of the coating material. The fire blanket is passed through the top wall of the coating roller 101, and then the fire blanket is folded back through the outer wall of the turning roller 104. The coating roller 101 is used to coat the surface of the conveyed fire blanket. The scraper 107 is used to scrape the surface of the fire blanket coated with the coating material, so that the coating thickness is evenly distributed on the surface of the fire blanket. The scraper 107 removes the excess coating material, which makes it easy for the device to evenly coat the coating material onto the surface of the fire blanket, so that the coating thickness is uniform and the uneven coating will affect the performance of the fire blanket.
[0022] The top wall of the fixed frame 105 is provided with a sliding groove, and the left and right side walls of the inner cavity of the sliding groove are screwed with adjusting screws 108. The adjusting screws 108 facilitate the movement of the connecting frame 106. The right end of the adjusting screws 108 passes through the right side wall of the fixed frame 105 and is equipped with a knob, thereby driving the scraper 107 to move and adjust. The connecting frame 106 is screwed to the outer wall of the adjusting screws 108.
[0023] In this embodiment: the connecting frame 106 is moved by rotating the adjusting screw 108, and the scraper 107 is moved by the connecting frame 106. The movement of the scraper 107 changes the distance between it and the fire blanket, which facilitates the application of coatings of different thicknesses and helps to scrape off excess material for recycling, thus improving the practicality of the device.
[0024] Gears 109 are fixedly connected to the rear ends of both the coating roller 101 and the turning roller 104. The coating roller 101 and the turning roller 104 rotate synchronously through the gears 109. The two sets of gears 109 mesh with each other. The coating roller 101 and the turning roller 104 have the same diameter, which makes the fire blanket conveying speed consistent.
[0025] In this embodiment: the coating roller 101 rotates to drive the lower gear 109 to rotate, the lower gear 109 drives the upper gear 109 to rotate, and the upper gear 109 drives the turning roller 104 to rotate, so that the rotation speed of the coating roller 101 and the turning roller 104 are kept consistent, which facilitates the conveying of the fire blanket, avoids slippage, and is conducive to coating the coating onto the fire blanket.
[0026] A support frame 110 is fixedly connected to the left side of the top wall of the outer casing 100. The support frame 110 facilitates the support of the feed roller 111 and the discharge roller 112. The feed roller 111 is provided on the lower side of the front and rear side walls of the inner cavity of the support frame 110, and the discharge roller 112 is provided on the upper side of the front and rear side walls of the inner cavity of the support frame 110.
[0027] In this embodiment: the support frame 110 is provided to support the feed roller 111 and the discharge roller 112. The feed roller 111 and the discharge roller 112 are used to support and guide the conveyed fire extinguishing blanket, so that the fire extinguishing blanket can be smoothly conveyed and moved in the coating mechanism, and the coating operation can be carried out.
[0028] The inner cavity of the liquid storage tank is funnel-shaped, and an observation port is provided on the front side wall of its outer shell 100. An observation plate 113 is fixedly connected to the inner wall of the observation port. The observation plate 113 is made of transparent material to facilitate the viewing of the paint level.
[0029] In this embodiment, the funnel-shaped design facilitates the collection of paint into the concave area, making it easier for the coating roller 101 to pick up the paint for coating. The observation plate 113 makes it easy to monitor the amount of paint and add paint in a timely manner, which is beneficial for the coating operation.
