Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pre-coating film production, in particular to a dust removal and smoke exhaust mechanism for a pre-coating film extrusion composite machine. Background Art
[0002] Pre-coating refers to the process of pre-gluing and rewinding plastic film before laminating it with paper printed products. The pre-coating factory first applies glue on the film according to the specifications and format, then rewinds it for the user to choose, and then laminates it with the printed product. Laminating, also known as film pasting, is a processing technology that coats plastic film with adhesive and bonds it to paper printed products after heating and pressurizing to form a paper-plastic integrated product. The printed product after lamination has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter, thereby improving the gloss and fastness of the printed product, making the color of the image and text more vivid and three-dimensional, and at the same time playing the role of waterproof, anti-fouling, wear-resistant, wrinkle-resistant, and chemical corrosion-resistant.
[0003] When feeding the existing composite machine for plastic pre-coated film processing, it is usually necessary to first stir the EVA powder by the screw to melt it and transport it to the die head, and then directly decompress it from the die head onto the plastic pre-coated film. After that, the glue stick and the pressing roller are pressed together to press the EVA hot melt adhesive onto the plastic pre-coated film. When the EVA raw material is hot-melted, a large amount of smoke and toxic gases such as carbon monoxide, carbon dioxide, benzene, etc. will be generated. When the composite machine is working, the smoke exhaust device above the composite machine feeding equipment is always working. For different situations of material smoke, this uncontrollable smoke exhaust method must have certain limitations and also increase the production cost of the enterprise. At the same time, the direct discharge of smoke will cause environmental pollution and is not environmentally friendly. In addition, in the existing smoke exhaust device, the raw materials for treating waste gas and particles are not easy to replace. Utility Model Content

DETAILED DESCRIPTION
[0019] Please refer to the attached Figure 1-Figure 2 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0020] The utility model proposes a dust removal and smoke exhaust mechanism for a pre-coated film extrusion composite machine. When using the device, align the lower ends of a pair of sliding rods 14 corresponding to a filter screen 12 with the corresponding straight groove plate 13, push the filter screen 12 downward, and slide the pair of sliding rods 14 downward along the corresponding straight groove plate 13. When the lower end of the filter screen 12 fits the bottom of the filter box 10, stop pushing the filter screen 12, and then slide another filter screen 12 into another pair of straight groove plates 13, align the pair of sliding grooves through which the activated carbon box 11 passes with the pair of sliding rods 14, push the activated carbon box 11 downward, and fit the lower end of the activated carbon box 11 with the bottom of the filter box 10. After the filter screen 12 and the activated carbon box 11 are installed, the cover plate is fastened to the filter box 10 by a set of bolts, and after a proper amount of solution is poured into the filter box 7 through the liquid inlet pipe, the upper end of the liquid inlet pipe is sealed by the sealing cover, and the end of the deodorizing net 5 installed with the card plate 16 is passed through the rectangular slide groove, and the deodorizing net 5 is pushed inward until the card plate 16 is inserted into the card groove. At this time, a pair of retaining springs 6 clamp the corresponding corner of the deodorizing net 5. When the compound machine is started, the solenoid valve 3 is opened, and the motor 9 is started. At this time, the feeding box 1 is connected with the filter box 10 through the connecting pipe. When the feeding box 1 is started, smoke is generated, and the high-temperature smoke passes through the exhaust hood 2 and the connecting pipe. The smoke passes through the filter box 10, and the smoke first passes through a pair of filter screens 12 and then through the activated carbon box 11. The pair of filter screens 12 filters large particles in the smoke, and the activated carbon box 11 filters small particles in the smoke. The filter box 10 filters solid particles in the smoke, and the filtered exhaust gas enters the filter box 7 through the connecting pipe 2. The motor 9 drives a group of stirring rods 8 to rotate through the stirring shaft. The group of stirring rods 8 continuously stirs the solution to make the harmful gas in the exhaust gas fully react with the solution, while avoiding the exhaust pipe part close to the connecting pipe 2 when the solution is in a static state. The solution is saturated first, which not only makes the harmful gas removal more thorough, but also makes the solution more fully utilized. When the gas after the secondary filtration passes through the deodorizing net 5, the odor in the gas is removed by the deodorizing net 5, and the purified gas is discharged through the exhaust pipe 4. The device removes particulate impurities in the smoke through the filter box 10, and then reacts and removes the harmful gas in the exhaust gas through the solution of the filter box 7, avoiding the direct discharge of smoke to pollute the environment, and the filter net 12, activated carbon box 11 and deodorizing net 5 in the device are all detachable, which is convenient for timely replacement of purification materials to avoid adsorption saturation affecting the filtration efficiency.
