Description

Technical Field

[0001] This utility model belongs to the field of dust prevention technology in coated paper production, and in particular relates to a dust prevention device for coated paper production. Background Technology

[0002] Laminated paper, also known as coated paper, is a type of processed paper product in which a plastic film is laminated onto the base paper. This process typically uses polyethylene or polypropylene as the coating material, which is heated and melted and then evenly coated onto the paper surface before being cooled and cured. Laminated paper combines the flexibility and printability of paper materials with the waterproof, oil-proof, and tear-resistant properties of plastic film, and is widely used in many fields.

[0003] Currently, during the lamination process of paper, the high temperature generated during lamination and the resulting fine particles, along with dust from the equipment, can easily fall onto the film due to vibration. These falling particles and dust can cause uneven coating and defects, thus affecting the final quality of the product.

[0004] Therefore, we propose a dust prevention device for coated paper production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that, during the lamination process of paper, fine particles formed by the high temperature and cooling of the equipment, as well as dust on the equipment, easily fall onto the film due to vibration. These falling fine particles and dust can cause uneven coating and defects, thus affecting the final quality of the product. Therefore, this invention proposes a dustproof device for lamination paper production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dustproof device for coated paper production includes a fixed box. A limit frame is fixedly installed on the upper surface of the fixed box, and a first suction hood is fixedly installed on the bottom surface of the limit frame. An air pump is fixedly installed on the back of the fixed box. A first heat-conducting pipe is fixedly connected to the outer surface of the input end of the air pump. The end of the first heat-conducting pipe away from the air pump passes through the fixed box and is fixedly connected to a gas delivery pipe. The end of the gas delivery pipe away from the first heat-conducting pipe passes through the fixed box and the limit frame in sequence and extends into the interior of the limit frame. The outer surface of the gas delivery pipe is flush with the inner wall of the limit frame. The gas supply pipe is fixedly connected to the upper surface of the first suction hood at one end away from the first heat-conducting pipe. A collection box is fixedly installed on the back of the fixed box. A filter screen is slidably connected to the inner wall of the collection box. The input end of the air pump passes through the collection box and extends into the interior of the collection box. A delivery pipe is fixedly connected to the upper surface of the collection box. Second suction hoods arranged at equal intervals are fixedly installed on the outer surface of the delivery pipe. A protective frame is fixedly installed on the bottom surface of the first suction hood. The outer surface of the delivery pipe is fixedly connected to the outer surface of the protective frame.

[0008] Preferably, six first connecting blocks are fixedly installed on the upper surface of the limiting frame, and each first connecting block has a first connecting hole on its upper surface.

[0009] Preferably, a feed pipe is fixedly connected to the upper surface of the fixed box, and a sealing cap is fitted onto the top end of the feed pipe.

[0010] Preferably, two second connecting blocks are fixedly installed on both sides of the fixed box, and each second connecting block has a second connecting hole on its front side.

[0011] Preferably, the back of the collection box is hinged to a switch door, and a pull block is fixedly installed on the back of the switch door.

[0012] Preferably, a limiting block is fixedly installed on the inner bottom wall of the fixed box, a second heat-conducting pipe is fixedly installed on the upper surface of the limiting block, the outer surface of the second heat-conducting pipe is fixedly connected to the inner wall of the fixed box, and the upper surface of the limiting block is fixedly connected to the outer surface of the first heat-conducting pipe.

[0013] Preferably, two flanges are fixedly installed on the outer surface of the second heat pipe, and each flange has mounting holes arranged at equal intervals on its right side.

[0014] Preferably, the back of the air pump is provided with four limiting bolts, one end of each limiting bolt passing through the air pump and extending into the interior of the fixed box, and each limiting bolt being threadedly connected to the fixed box.

[0015] In summary, the technical effects and advantages of this utility model are as follows: The suction force provided by the air pump draws air out of the first heat-conducting pipe, creating a negative pressure inside the pipe. This allows the first suction hood to absorb the high temperature generated during the paper coating process. The high-temperature gas is then directly transported to the first heat-conducting pipe via the gas delivery pipe, allowing the heat from the gas to be transferred to the heat storage salt in the fixed box, thus storing the high-temperature energy. The suction force provided by the air pump also draws air out of the collection box, creating a negative pressure inside. This allows the second suction hood to absorb dust that falls from the equipment due to vibration. The dust is then directly transported to the collection box via the delivery pipe, and the filter screen blocks the incoming dust, preventing it from scattering. This ensures that during the paper coating process, small particles formed by the high temperature of the coating process and dust on the equipment do not easily fall onto the film due to vibration, guaranteeing the final product quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4This embodiment provides a dustproof device for coated paper production. The dustproof device includes a fixed box 1. A limiting frame 2 is fixedly installed on the upper surface of the fixed box 1. A first suction hood 3 is fixedly installed on the bottom surface of the limiting frame 2. An air pump 4 is fixedly installed on the back of the fixed box 1. A first heat conduction pipe 5 is fixedly connected to the outer surface of the input end of the air pump 4. Six first connecting blocks 12 are fixedly installed on the upper surface of the limiting frame 2. Each first connecting block 12 has a first connecting hole 13 on its upper surface. The limiting frame 2 can be easily installed through the first connecting blocks 12, thereby preventing the limiting frame 2 from falling or shifting, and increasing the stability of the device.

[0023] The end of the first heat-conducting pipe 5 away from the air pump 4 passes through the fixed box 1 and is fixedly connected to the gas supply pipe 6. The end of the gas supply pipe 6 away from the first heat-conducting pipe 5 passes through the fixed box 1 and the limiting frame 2 in sequence and extends into the interior of the limiting frame 2. The outer surface of the gas supply pipe 6 is fixedly connected to the inner wall of the limiting frame 2. The upper surface of the fixed box 1 is fixedly connected to the feed pipe 14. The top end of the feed pipe 14 is fitted with a sealing cap 15. The heat storage salt can be easily put into the fixed box 1 through the feed pipe 14. The sealing cap 15 can seal the feed pipe 14, thereby preventing external impurities from entering the fixed box 1.

[0024] The end of the gas supply pipe 6 away from the first heat conduction pipe 5 is fixedly connected to the upper surface of the first suction hood 3. A collection box 7 is fixedly installed on the back of the fixed box 1. A filter screen 8 is slidably connected to the inner wall of the collection box 7. The input end of the air pump 4 passes through the collection box 7 and extends into the interior of the collection box 7. Two second connecting blocks 16 are fixedly installed on both sides of the fixed box 1. Each second connecting block 16 has a second connecting hole 17 on its front. The second connecting blocks 16 can be used to limit the fixed box 1, making it easy to install the fixed box 1 and increasing the convenience of the device.

[0025] The upper surface of the collection box 7 is fixedly connected to a conveying pipe 9. The outer surface of the conveying pipe 9 is fixedly installed with second suction hoods 10 arranged at equal intervals. The bottom surface of the first suction hood 3 is fixedly installed with a protective frame 11. The outer surface of the conveying pipe 9 is fixedly connected to the outer surface of the protective frame 11. The back of the collection box 7 is movably hinged with a switch door 18. The back of the switch door 18 is fixedly installed with a pull block 19. The switch door 18 can be manually opened by pulling the pull block 19, which facilitates the centralized treatment of the collected dust and increases the convenience of dust treatment.

[0026] A limiting block 20 is fixedly installed on the inner bottom wall of the fixed box 1. A second heat conduction pipe 21 is fixedly installed on the upper surface of the limiting block 20. The outer surface of the second heat conduction pipe 21 is fixedly connected to the inner wall of the fixed box 1. The upper surface of the limiting block 20 is fixedly connected to the outer surface of the first heat conduction pipe 5. The limiting block 20 can limit the first heat conduction pipe 5 and the second heat conduction pipe 21. The second heat conduction pipe 21 can conveniently utilize the heat stored in the deheating salt, which increases the practicality of the device.

[0027] Two flanges 22 are fixedly installed on the outer surface of the second heat pipe 21. Each flange 22 has mounting holes 23 arranged at equal intervals on its right side. The flanges 22 facilitate the connection between the second heat pipe 21 and the external conduit, thereby making it easier to utilize the heat in the deheating salt and further increasing the practicality of the device.

[0028] Four limiting bolts 24 are provided on the back of the air pump 4. The end of each limiting bolt 24 near the air pump 4 passes through the air pump 4 and extends into the interior of the fixed box 1. Each limiting bolt 24 is threadedly connected to the fixed box 1. The limiting bolts 24 can increase the stability of the air pump 4, thereby preventing the air pump 4 from shaking or shifting during operation and increasing the stability of the air pump 4.

[0029] The working principle of this utility model is as follows: In use, the air pump 4 is first connected to the power supply. The first connecting block 12 and the second connecting block 16 facilitate the installation of the limiting frame 2 and the fixed box 1, allowing the first suction hood 3 to be placed above the coated paper production device. The suction force provided by the air pump 4 draws air out of the first heat-conducting pipe 5, creating a negative pressure inside the first heat-conducting pipe 5. This allows the first suction hood 3 to absorb the high temperature generated during the paper coating process. The high-temperature gas is directly transported to the first heat-conducting pipe 5 through the gas delivery pipe 6, allowing the heat in the high-temperature gas to be transferred to the heat storage salt in the fixed box 1, thus storing the high-temperature energy. The flange 22 facilitates the connection between the second heat-conducting pipe 21 and the external conduit, allowing external liquid energy to be stored. The air can enter the second heat pipe 21, thereby utilizing the heat in the heat storage salt. The suction force provided by the air pump 4 can draw the air out of the collection box 7, making the inside of the collection box 7 negative pressure. Thus, the second suction hood 10 can absorb the dust that falls off the equipment due to vibration. The dust is then guided by the conveying pipe 9 and directly transported to the collection box 7. The filter screen 8 can block the incoming dust, thus preventing the dust from flying around. This prevents the fine particles formed by the high temperature of the equipment during the coating process of paper from falling onto the film due to vibration, and ensures the final quality of the product. The manual opening and closing door 18 can be opened by holding the pull block 19, which facilitates the centralized treatment of the collected dust, making the dust prevention device for coated paper production more practical.
