Description

Technical Field

[0001] This utility model relates to the field of automotive parts coating technology, and in particular to a sealing structure for a large cross-section air outlet. Background Technology

[0002] In the automotive parts coating industry, improvements have been made to the coating process. The industry has promoted the use of dry-type cardboard box technology in spray booths, which prevents the paint mist generated during spraying from mixing with water. The paint mist is forced to pass through a dry filter box by a centrifugal fan, and the paint mist is intercepted and captured in multiple stages. The cardboard boxes containing paint mist that are replaced are directly sent to a micro-waste disposal site for incineration, thus achieving the goal of not generating paint mist-containing wastewater during the spraying process.

[0003] Currently, the air inlets and outlets of dry cardboard box paint mist capture processes are all large-sized cross-sections. The industry's sealing method is to clamp and seal on all four sides. Because the cardboard box material is corrugated paper, clamping on all four sides will cause the cardboard to deform and easily leak air. The four-sided cross-section structure creates four turning points, which are very likely to become sealing dead angles and air leakage points, posing a great hidden danger. As a result, the air balance of the project cannot be adjusted, which in turn leads to a decrease in the paint spraying yield. Therefore, we propose a sealing structure for a large-section air outlet. Utility Model Content

[0004] The main objective of this invention is to provide a sealing structure for a large cross-section air outlet. It replaces the existing four-sided clamping sealing method for dry cardboard boxes in the automotive parts coating industry with a cylinder-controlled pressing module that presses the dry cardboard box from top to bottom for compression sealing. This eliminates dead corners after the dry cardboard box is sealed under pressure, effectively solving the air leakage problem when using dry cardboard boxes in automotive parts coating. Furthermore, after installing a rubber sealing ring at the bottom frame of the pressing module, the cylinder's extension and retraction presses the rubber sealing ring tightly onto the air outlet cross-section of the large dry cardboard box, ensuring effective sealing of the working section. Because the compression sealing is achieved through a cylinder, when the cylinder retracts, the cross-section retracts upwards, making it easier to create space for replacing the cardboard box. This significantly simplifies the replacement of the cardboard box and effectively solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A sealing structure for a large cross-section air outlet includes a coating treatment box frame, a tray trolley, and a large dry cardboard box. The tray trolley is inserted into the bottom of the coating treatment box frame, and the large dry cardboard box inserted into the coating treatment box frame rests on the surface of the tray trolley. The structure also includes a connecting box, a horn cover, a spray head, an angle bracket, a cylinder, a side connecting plate, a lower pressure module, an upper sealing module, a rubber sealing ring, and a bottom frame. The connecting box is installed on the top of the coating treatment box frame, and a horn cover is installed at the upper opening of the connecting box. A spray head is installed inside the horn cover. A cylinder is installed on the inner wall of the connecting box via an angle bracket, and a side connecting plate is installed at the telescopic rod head of the cylinder. The side connecting plate is fixed to the outside of the lower pressure module. The upper sealing module is interconnected between the lower pressure module and the bottom opening of the horn cover. A bottom frame is fixed below the lower pressure module, and a rubber sealing ring is fitted onto the frame of the bottom frame.

[0007] Furthermore, the body of the connecting box is fixed at the top opening of the coating treatment box frame, and a bottom cover with a horn cover is inserted into the upper opening of the connecting box.

[0008] By adopting the above technical solution, after the speaker cover is installed in the connecting box, the speaker cover can communicate with the connecting box, thereby enabling the speaker cover to communicate with the chamber of the coating treatment box frame through the connecting box.

[0009] Furthermore, the frame of the corner bracket is bolted to the inner wall of the connecting box, and a cylinder is bolted to the frame of the corner bracket.

[0010] By adopting the above technical solution, the angle bracket can be used for cylinder mounting support after being installed in the connecting box.

[0011] Furthermore, the telescopic rod of the cylinder extends out of the corner seat bracket, and after the telescopic rod of the cylinder is screwed with a nut, it passes through the plate hole opened on the surface of the side connecting plate, and the nut is screwed at the head of the telescopic rod of the cylinder that passes through the side connecting plate.

[0012] By adopting the above technical solution, the cylinder's telescopic rod is locked in place with two sets of nuts at the side connecting plate, thus facilitating the cylinder to drive the pressing module through the side connecting plate.

[0013] Furthermore, a groove is provided at the body of the rubber sealing ring, and a bottom frame is clamped in the groove of the rubber sealing ring.

[0014] By adopting the above technical solution, the rubber sealing ring can be snapped onto the outside of the bottom frame with a groove.

[0015] Furthermore, the surface of the lower pressure module between the cylinders has a raised frame for engaging with the upper sealing module, and the upper opening of the upper sealing module away from the lower pressure module is fitted outside the bottom cover opening of the horn cover.

[0016] By adopting the above technical solution, the sleeve of the upper sealing module can be fitted onto the convex frame of the lower pressing module and the bottom cover opening of the horn cover to connect them.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model changes the existing method of four-sided clamping and sealing of dry large cardboard boxes in the auto parts coating industry to a contact method of pressing down from top to bottom using a cylinder-controlled pressing module to press and seal the dry large cardboard box. This ensures that no dead corners are generated after the dry large cardboard box is sealed under pressure, effectively solving the air leakage problem when dry large cardboard boxes are used in auto parts coating.

[0019] Furthermore, after installing a rubber sealing ring at the bottom frame of the pressing module, the rubber sealing ring is pressed against the air outlet section of the large dry carton by the extension and retraction of the cylinder, ensuring effective sealing of the working section. Since the pressing and sealing is achieved by the cylinder, when the cylinder retracts, the section retracts upward, making it easier to make room to replace the carton, thus making it very easy to replace the new carton.
