Description

Technical Field

[0001] The utility model relates to the technical field of powder coating production, in particular to a cooling device for powder coating production. Background Art

[0002] Powder coating is a solid coating in the form of fine powder. Powder coating is divided into two categories: thermoplastic powder coating and thermosetting powder coating. Powder coating is a new type of solvent-free 100% solid powder coating. It is a special type of coating that is transferred to the coated object in powder form, melted and solidified through baking to form a film. Powder coating needs to be melted and mixed before extrusion during production. The molten material from the extruder is squeezed into thin sheets through a pressure roller and then conveyed forward through a transmission device 1. During the conveying process, the thin sheet material is cooled and hardened by a cooling device, and then the thin sheet is crushed to form a powder coating.

[0003] Existing powder coating cooling devices usually use fans to blow air from above the flake molten material for cooling. This cooling method has low efficiency and poor cooling effect, thus affecting the quality of the produced powder coating products. Utility Model Content

[0017] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.

[0018] like Figure 1-4As shown, the utility model provides a cooling device for powder coating production, which is installed on a flaky powder coating transmission device 1, and includes a refrigeration compressor 2, an air pump 3, and an air pipeline 4. The refrigeration compressor 2 is provided in plurality and installed side by side on one side of the transmission device 1, and is arranged in sequence from the upstream of the powder coating transmission direction as a first refrigeration compressor 2, a second refrigeration compressor 2...; the air pump 3 is provided in plurality and installed side by side on the other side of the transmission device 1, and is arranged in sequence from the upstream of the powder coating transmission direction as a first air pump 3, a second air pump 3...; the air outlet of the refrigeration compressor 2 corresponds to the corresponding air inlet of the air pump 3; the air outlet of the nth air pump 3 is connected to the air inlet of the n+1th refrigeration compressor 2 through the air pipeline 4 arranged below the transmission device 1. Start the refrigeration compressor 2 and the air pump 3, and the cold air blown out from the first refrigeration compressor 2 blows over the surface of the powder coating being transmitted on the transmission device 1 to cool the powder coating, and then is absorbed by the first air pump 3 opposite, enters the second refrigeration compressor 2 through the air pipeline 4 under the transmission device 1 to be refrigerated again, and then is blown out to cool the powder coating, and then is attracted by the second air pump 3 and blown out from the third refrigeration compressor 2 to cool the powder coating; thereby forming a spiral cold air circulation, increasing the cooling effect on the powder coating, improving the cooling efficiency of the powder coating, allowing the cold air to be circulated and repeatedly refrigerated, thereby improving the cooling effect on the powder coating, and at the same time, the cooling of the cooled air again also reduces the power of the refrigeration compressor 2, thereby achieving an energy-saving effect.

[0019] The air outlet of the refrigeration compressor 2 is provided with a filter head 5 through a thread, and a filter screen 6 for filtering impurities is provided at the end of the filter head 5. After the cold air blown out from the refrigeration compressor 2 passes through the filter screen 6, dust impurities in the air can be filtered to prevent dust impurities from being blown onto the powder coating to pollute the powder coating and affect the quality of the powder coating. The filter head 5 can also be screwed off through the thread, so as to facilitate replacement.

[0020] The transmission device 1 is provided with a protective cover 7 having a U-shaped cross section, and baffles 8 are provided at the front and rear ends of the protective cover 7. A relatively closed cooling space is formed inside the protective cover 7 and the baffles 8, which reduces the outflow of cold air, thereby increasing the cooling effect on the powder coating.

[0021] The lower end of the baffle 8 is provided with a roller 9 for facilitating the movement of the flaky powder coating. The roller 9 can roll the powder coating when it moves, thereby preventing the powder coating from being scratched, increasing the airtightness in the protective cover 7, and thus increasing the cooling effect in the protective cover 7.

[0022] The baffle 8 is mounted on the protective cover 7 in a sliding manner. The protective cover 7 is provided with an adjusting device 10 for controlling the baffle 8 to slide up and down. The adjusting device 10 facilitates the baffle 8 to slide up and down, so as to check the cooling condition in the protective cover 7 and the cooling condition of the powder coating.

[0023] The adjusting device 10 includes a support plate 11, a screw rod 12, and a double-axis motor 13. The screw rod 12 is installed on the support plate 11 arranged on the top of the protective cover 7 through a bearing. The lower end of the screw rod 12 is threadedly installed in a threaded hole opened at the upper end of the baffle 8. The double-axis motor 13 is installed on the support plate 11, and two output shafts are respectively connected to the upper ends of the screw rod 12 at both ends through a worm gear transmission. The double-axis motor 13 drives the screw rod 12 to rotate in the threaded hole set on the baffle 8 so that the baffle 8 moves up and down along the screw rod 12, thereby opening or closing the baffle 8, which is convenient for checking the cooling condition of the powder coating in the protective cover 7.

[0024] Working process:

[0025] Start the refrigeration compressor 2 and the air pump 3, and the cold air blown out from the first refrigeration compressor 2 blows over the surface of the powder coating being transmitted on the transmission device 1 to cool the powder coating, and then is absorbed by the first air pump 3 opposite, enters the second refrigeration compressor 2 through the air pipeline 4 under the transmission device 1 to be refrigerated again, and then is blown out to cool the powder coating, and then is attracted by the second air pump 3 and blown out from the third refrigeration compressor 2 to cool the powder coating; thereby forming a spiral cold air circulation, increasing the cooling effect on the powder coating, improving the cooling efficiency of the powder coating, allowing the cold air to be circulated and repeatedly refrigerated, thereby improving the cooling effect on the powder coating, and at the same time, the cooling of the cooled air again also reduces the power of the refrigeration compressor 2, thereby achieving an energy-saving effect.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
