Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum hot stamping, and in particular to a powder blowing device for electroplated aluminum hot stamping. Background Technology

[0002] Electroplated aluminum hot stamping is a surface finishing process widely used in printing, packaging, bookbinding, and decorative materials. It uses a material called "electroplated aluminum foil" (also known as hot stamping foil) to precisely transfer decorative materials from the electroplated aluminum layer to the surface of the substrate through a heat-pressing transfer method.

[0003] Chinese Patent No.: CN202422398136.4 A blowing device for electroplated aluminum powder on a hot stamping machine. The blowing device is installed at the paper output of the hot stamping unit of the hot stamping machine. During the production process, pressurized air is blown out from the air nozzle to blow away the electroplated aluminum powder adhering to the printing paper.

[0004] However, the nozzles in this device cannot be replaced, and different models or specifications of nozzles can produce different airflow patterns (such as concentrated jets, fan-shaped airflows, etc.). For example, for fine particle residues, a high-concentration airflow is suitable; while for large areas with slight adhesion, a wide fan-shaped airflow is more suitable. The inability to quickly replace the appropriate nozzle will make it difficult to achieve the best cleaning effect.

[0005] Therefore, how to make the air nozzles on the extension tube replaceable has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a powder blowing device for electroplated aluminum hot stamping that can meet different usage requirements by selecting to install a first air nozzle or a second air nozzle to change the shape and size of the air outlet.

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a mounting base and a purger. The purger includes an air collection pipe and an air inlet pipe. The air collection pipe has several extension pipes spaced apart along the axial direction, and each extension pipe is provided with a first air nozzle. It also includes a second air nozzle of the same number as the first air nozzles. The mounting base has detachable fittings on both its left and right sides. The left and right sides of the air collection pipe are rotatably mounted in their respective fittings. Each first air nozzle and each second air nozzle is detachably connected to its corresponding extension pipe. Each first air nozzle has a flared opening, while each second air nozzle has a flat opening.

[0008] The present invention is further configured to include nuts in the same number as each of the first air nozzles. Each first air nozzle includes a mating section for sleeved air manifold and an air outlet section located below the mating section. The outer periphery of the mating section is provided with an external thread, which is threadedly engaged with the nut. The second air nozzle includes a connecting section with the same shape and size as the mating section.

[0009] The present invention is further configured such that: each of the extension tubes includes an installation section into which a corresponding mating section or connecting section is inserted; the installation section is a hollow frustum and is tapered from top to bottom; the mating section includes an installation groove for the installation section to be inserted; the shape and size of the installation groove are adapted to the installation section.

[0010] The present invention is further configured such that: each of the mating bodies is provided with a mounting position for the mounting base to be inserted, each mating body includes mating plates located on the left and right sides of the mounting position, each of the mating plates is provided with a socket, and the mounting base is provided with screw holes corresponding to each socket.

[0011] The present invention is further configured such that the mounting base is integrally formed with limiting components on both the front and rear sides of each mating plate.

[0012] The present invention is further configured such that: the left and right sides of the gas collection pipe are respectively rotatably installed with corresponding mating bodies, and the left and right sides of the gas collection pipe are fixedly installed with first gears. Each mating body is rotatably installed with a second gear that meshes with the corresponding first gear. One end of each second gear protrudes from the corresponding mating body. Each mating body can be detachably installed with a cover. The upward projection of each second gear falls on the corresponding cover.

[0013] The present invention is further configured such that: each cover includes mounting plates on the left and right sides, and each mounting plate is threadedly engaged with the corresponding mating body.

[0014] By adopting the above technical solution, the flared first nozzle is suitable for blowing away large areas of light dust, while the flat second nozzle has concentrated airflow and strong impact force, making it suitable for cleaning stubborn residues or narrow gaps. Users can flexibly change the nozzle type according to actual working conditions to improve cleaning adaptability and efficiency. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-9As shown, this utility model discloses a powder blowing device for hot stamping of electroplated aluminum foil, including a mounting base 1 and a blower 2. The blower 2 includes an air manifold 21 and an air inlet pipe 22. The air inlet pipe 22 is connected to an air compressor or a central air supply system (this is prior art and will not be described in detail here). During hot stamping, the aluminum plating layer and color layer on the electroplated aluminum foil will be partially transferred to the substrate (such as paper, plastic, leather, etc.), while its base film (usually PET film) will be peeled off. During this peeling process, due to pressure, temperature, and the characteristics of the material itself, tiny aluminum layer or coating debris may fall off, forming fine powder. Furthermore, tiny burrs or debris may be generated at the edges during the cutting process. If the surface of the substrate itself has dust or paper dust, the high temperature and pressure during hot stamping may cause these substances to be squeezed, carbonized, or mixed with the fallen aluminum layer, forming visible powder or spots. Therefore, it is necessary to use the blower 2 to blow away these powders and debris. The mounting base 1 is then inserted into the substrate. On the electroplating aluminum hot stamping equipment, the blower 2 is aligned with the position where the powder to be blown away, and the air compressor and other input equipment are started to achieve the powder blowing. The air collection pipe 21 is provided with a number of extension pipes 213 at intervals along the axial direction, and each extension pipe 213 is detachably installed with a first air nozzle 3 by means of threads, etc. It also includes a number of second air nozzles 4 equal to the number of first air nozzles 3. The left and right sides of the mounting base 1 are detachably installed with mating bodies 11 by means of bolts, etc. The left and right sides of the air collection pipe 21 are respectively rotatably installed in the corresponding mating bodies 11. Each first air nozzle 3 and second air nozzle 4 is detachably connected to the corresponding extension pipe 213 by means of threads, etc. Each first air nozzle 3 is flared and each second air nozzle 4 is flat. The flared first air nozzle 3 is suitable for blowing away light dust over a large area, while the flat second air nozzle 4 has concentrated airflow and strong impact force, which is suitable for cleaning stubborn residues or narrow gaps. Users can flexibly change the type of air nozzle according to the actual working conditions to improve cleaning adaptability and efficiency.

[0032] The system also includes nuts 5 in the same number as each of the first air nozzles 3. Each first air nozzle 3 includes a mating section 31 that fits onto the manifold 21 and an outlet section 32 located below the mating section 31. The mating section 31 has an external thread 311 on its outer periphery, which is threaded into the nut 5. The second air nozzle 4 includes a connecting section 41 that is the same shape and size as the mating section 31. The mating section 31 of the first air nozzle 3 and the connecting section 41 of the second air nozzle 4 have the same shape and size, indicating that they can be used interchangeably in the same position. This allows for easy replacement of air nozzles of different shapes without changing the pipes or structures. After the mating section 31 or the connecting section 41 is fitted onto the manifold 21, the nut 5 is screwed in, and the external thread 311 engages with the nut 5 to lock it in place, preventing the first air nozzle 3 or the second air nozzle 4 from loosening or falling off under high-pressure airflow and improving sealing and safety. The connection and separation of the first air nozzle 3 or the second air nozzle 4 from the manifold 21 can be completed by rotating the nut 5, thus improving operational convenience.

[0033] Each of the extension tubes 213 includes an installation section 2131 into which a corresponding mating section 31 or connecting section 41 is inserted. The installation section 2131 is a hollow frustum and is tapered from top to bottom. The mating section 31 includes an installation groove 312 for the installation section 2131 to be inserted. The shape and size of the installation groove 312 are adapted to the installation section 2131. Since the installation section 2131 is frustum, its bottom, i.e., the side with the smallest diameter, will enter the installation groove 312 first during the process of inserting the installation section 2131 into the installation groove 312, thus facilitating the alignment of the two. At the same time, since the installation groove 312 and the installation section 2131 are adapted to each other, after the position of the installation section 2131 in the installation groove 312 is determined, the circumferential direction of the installation section 2131 will fit against the inner wall of the installation groove 312 to form a surface seal, thereby reducing the risk of gas leakage.

[0034] Each of the mating bodies 11 is provided with a mounting position 111 for the mounting base 1 to be inserted. Each mating body 11 includes mating plates 112 located on the left and right sides of the mounting position 111. Each mating plate 112 is provided with a socket 1121, and the mounting base 1 is provided with screw holes 12 corresponding to each socket 1121. After the mating body 11 is inserted into the left and right sides of the mounting base 1, bolts that are adapted to the shape of the screw holes 12 are inserted, so that each mating plate 112 can be stably connected to the mounting base 1, thereby making the air manifold 21 stably located on the mounting base 1, and thus fixing the mounting base 1 above the dust blowing position of the electroplated aluminum hot stamping equipment.

[0035] The mounting base 1 is integrally formed with limiting members 13 on both the front and rear sides of each mating plate 112. Each mating plate 112 is placed between the limiting members 13 on the corresponding side of the mounting base 1. At this time, the two ends of the limiting members 13 will abut against the mating plate 112, thereby realizing the positioning of the mating body 11 on the mounting base 1 and facilitating the insertion of bolts into the insertion hole 1121 and the thread engagement with the screw hole 12.

[0036] The gas collection pipe 21 has corresponding mating bodies 11 rotatably mounted on its left and right sides. First gears 211 are fixedly mounted on both sides of the gas collection pipe 21 via key connections, welding, or other methods. Each mating body 11 has a second gear 113 rotatably mounted to mesh with the corresponding first gear 211. One end of each second gear 113 protrudes from its corresponding mating body 11. Each mating body 11 has a cover 114 detachably mounted on its top via bolts or other methods. The upward projection of each second gear 113 falls onto its corresponding cover 114. Rotating the exposed second gear 113 causes it to turn. The movement causes the first gear 211 to rotate. As the first gears 211 on both sides of the air collection pipe 21 rotate, the air collection pipe 21 will rotate, which can change the blowing angle of the first air nozzle 3 or the second air nozzle 4 located on the air collection pipe 21. The meshing transmission is stable and not easy to slip, so that the air collection pipe 21 will not rotate arbitrarily without the action of external force. When no adjustment is needed, the cover 114 is installed above each of the second gears 113 to complete the connection with the mounting base 1, so that external dust is difficult to reach the second gears 113 and cannot contact the second gears 113 and the first gear 211 when no adjustment is needed.

[0037] Each cover 114 includes mounting plates 1141 on the left and right sides. Each mounting plate 1141 is threadedly engaged with the corresponding mating body 11. The threaded mounting plate 1141 allows the cover 114 to be easily unscrewed, thereby turning the second gear 113 to rotate the air manifold 21. When the mounting plate 1141 is connected to the mating body 11, it cannot contact the second gear 113.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
