[0001] This utility model belongs to the technical field of printing dust removal equipment, and relates to a bio-based coated dust collection device. Background Technology

[0002] The printing process of cigarette packaging boxes requires bio-based lamination. Bio-based lamination easily generates dust, which adheres to the rollers and affects the lamination effect. The inventor currently uses a scraper installed on one side of the bio-based lamination conveying roller for collection. After collection, the dust falls into the collection trough. However, the existing dust collection is located at the blade edge and is difficult to gather in the collection trough, causing the collected dust to be re-adsorbed onto the rollers, still affecting the lamination effect. Utility Model Content

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] Example 1: Refer to Figure 1-7 As shown, a bio-based coated dust collection device includes a roller frame 1, a dust scraper 2, a dust hood 3, and a negative pressure dust collection device 4, wherein the negative pressure dust collection device 4 is an industrial vacuum cleaner. The dust scraper 2 is fixedly connected to the roller frame 1 at both ends. The dust scraper 2 is located on one side of the bio-based film conveying roller 5 and can gather dust to the top surface of the blade after rotation. The blade of the dust scraper 2 abuts against the cylindrical length of the bio-based film conveying roller 5, and the blade length is greater than the length of the bio-based film conveying roller 5. The dust collection hood 3 is a strip structure. Both ends of the length direction are installed above the dust scraper 2 through two brackets 6, and the bottom opening can cover the entire dust scraper 2. The brackets 6 are fixedly connected to the roller frame 1. The dust collection hood 3 is provided with a receiving cavity with an opening at the bottom. The negative pressure dust collection device 4 is connected to the dust collection hood 3.

[0014] To achieve stable dust collection, such as Figure 7 As shown, the dust scraper 2 includes a blade 201, a blade plate 202, an elastic blade 203, a hard pressure plate 204, and a pressure plate 205. Two blades 201 are used, respectively fixedly connected to both sides of the roller frame 1. The blade plate 202 is fixedly connected to both ends of the two blades 201. The elastic blade 203 elastically abuts against the bio-based film-coated conveyor roller 5. The hard pressure plate 204 presses against the upper surface of the elastic blade 203 and is flush with the side of the blade plate 202 facing the bio-based film-coated conveyor roller 5. The pressure plate 205 presses against the hard pressure plate 204, and screws 206 are used to fix the pressure plate 205, hard pressure plate 204, and elastic blade 203 to the blade plate 202. The hard pressure plate, in conjunction with the pressure plate, ensures the rigidity and stability of the elastic blade's cutting edge, preventing excessive flexibility that would result in poor dust removal from the roller. After the elastic blade wears out, only the elastic blade needs to be replaced. This dust scraper structure is convenient and quick to install, remove, and maintain.

[0015] To facilitate adjustment of the elastic contact between the blade and the roller, the blade shank 201 is a cylindrical rod with an inlay groove 2011 at one end. One end of the blade plate 202 is inserted into the inlay groove 2011 and locked in place by a fastener 2012, which is a screw. The other end of the blade shank 201 is embedded in a locking member 207. The bottom of the locking member 207 is fixedly connected to the inner wall of the roller frame 1 via a support angle member 208, which is an angle iron. A notch 2072 is provided on one side of the connecting hole 2071 of the locking member 207, and a vertically arranged locking screw 2073 is used to lock it in place at the notch 2072. One of the blade shanks 201 is fixedly connected to... An adjusting sleeve 209 is attached, and the adjusting sleeve 209 has multiple threaded holes 2091 on its outer circumference. The threaded holes 2091 are detachably and fixedly connected to a rocker arm 210. After inserting the cutter bar into the connecting hole, the cutter bar is slightly tightened but the adjusting sleeve can still be rotated to drive the cutter bar to rotate. At this time, the rocker arm is controlled to drive the adjusting sleeve to rotate, which in turn drives the cutter bar to rotate. The rotation of the cutter bar drives the cutter plate to rotate. The rotation of the cutter handle causes the elastic blade, which is fixedly connected to it, to rotate and make elastic contact with the roller surface. When the best contact effect is achieved, the fasteners at both ends are tightened. If the elastic blade has been used for a long time, the fasteners are loosened again for adjustment, and then the blade is re-fixed after adjustment.

[0016] To improve the dust collection effect, the top of the dust collection hood 3 is equipped with multiple converging hoods 7, which are smaller at the top and larger at the bottom. The top of each converging hood 7 is connected to the main pipe 9 in parallel through branch pipes 8. The main pipe is connected to the negative pressure dust collection device 4. Through multiple converging hoods, the dust generated in each section can be collected and discharged separately, improving the dust collection effect and avoiding the impact of excessively long dust collection hoods on the discharge effect.

[0017] To ensure safe dust collection even in the event of a dust removal device malfunction, a dust collection trough 10 is installed on the other side of the dust scraper away from the bio-based film-coated conveyor roller 5. The dust collection trough 10 is supported at both ends by two cantilever support members 11, which are fixedly connected to the inner walls of both sides of the roller frame 1. The dust collection trough facilitates manual cleaning of accumulated dust. An inlay groove 1101 is provided on the side of the cantilever support member 11 facing the dust collection trough 10, which can be embedded into one end of the dust collection trough 10. The placement and installation of the inlay groove facilitates the loading and unloading of the dust collection trough. A slope 211 is provided on the side of the pressure plate 205 facing the elastic blade 203. The slope facilitates the collection of dust, which can then be manually cleaned by brushing it into the dust collection trough.

[0018] In order to reduce energy consumption, each collection hood is equipped with a dust sensor 12. The dust sensor detects the dust level and controls the duration of starting and stopping the negative pressure suction equipment, thereby reducing energy consumption and avoiding energy consumption when there is very little dust.

[0019] Example 2: The operation method of a bio-based film-coated dust collection device is as follows: When in use, if any dust sensor detects no dust for a first set time, the negative pressure suction device is stopped. After a second set time, the negative pressure suction device is restarted to perform suction, and the dust sensor is used for detection. The aforementioned detection and start / stop operation process of the negative pressure suction device is repeated to perform the dust collection operation.

[0020] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
