Description

Technical Field

[0001] This utility model relates to the field of drying equipment, specifically an acrylic multilayer coating drying device. Background Technology

[0002] Acrylic coatings are single-component, self-drying, weather-resistant, and anti-corrosion coatings made by adding internationally recognized long-life chlorosulfonated polyethylene rubber, weather-resistant pigments and fillers, and weather-resistant additives to traditional acrylic resins using advanced processes.

[0003] For example, patent CN214701675U discloses a water-based paint drying device that can dry paint evenly and comprehensively. The device includes a box body with a slot on the front end. A first fixing block and a second fixing block are fixedly connected to the inner wall of the box body. A first housing is located between the first and second fixing blocks and at the upper end. A second housing is located below the first housing. Heating plates are fixedly connected to both the first and second housings. An anti-blocking frame is provided between the heating plates. A connecting block is provided at the left end of the limiting plate. A nut is fixedly connected to the connecting block. A lead screw is provided inside the nut. A motor is provided at the upper end of the lead screw.

[0004] The aforementioned patent features a heating plate inside the box, and the height of the support frame can be changed by a motor drive. By changing the height of the support frame, the heating plate can dry the top and bottom of the material, resulting in high drying quality, which is worth promoting. However, the disadvantage of the aforementioned patent is that water-based coatings are usually sprayed in multiple layers, requiring multiple drying processes. When using the aforementioned patent, the feeding and unloading of the board material is very inconvenient.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] Please see Figure 1-10 An acrylic multilayer coating drying device includes a drying box 1; the drying box 1 is provided with a plurality of drying racks 2, which are evenly spaced from top to bottom; a hot air assembly 3 is also provided at the bottom of the drying box 1.

[0032] The drying oven 1 has a maintenance window 101 on the rear side, and a maintenance door 102 is installed at the maintenance window 101. The maintenance door 102 is rotatably connected to the side of the maintenance window 101 by a hinge, and a maintenance door handle 103 is installed on the maintenance door 102. The front end of the drying oven 1 also has several inlet and outlet ports 104.

[0033] In this solution, since the hot air assembly 3 needs to draw air from the bottom of the drying box 1, support feet 105 are also vertically fixed at the four corners of the bottom of the drying box 1. The support feet 105 are used to suspend the bottom of the drying box 1, so as to facilitate air intake from the bottom of the drying box 1.

[0034] The top of the drying chamber 1 is also connected to an exhaust branch pipe 106, and at least two exhaust branch pipes 106 are provided. The tops of the two exhaust branch pipes 106 are connected to the exhaust main pipe 107; the exhaust main pipe 107 is connected to the waste gas treatment equipment in the prior art.

[0035] like Figure 6-7 As shown, the hot air assembly 3 includes an electric heating element 301, a fan 302, and a guide shroud 303. The guide shroud 303 is fixedly installed at the bottom of the drying chamber 1, wherein the fan 302 is fixedly installed at the center of the bottom of the guide shroud 303, and the electric heating element 301 is fixedly installed at the top of the guide shroud 303. An air inlet channel 304 is provided at the bottom of the guide shroud 303, and the bottom of the air inlet channel 304 extends to the bottom of the drying chamber 1.

[0036] like Figure 8-9As shown, the drying rack 2 includes a shelf 201, which is used to place the boards to be dried.

[0037] In this solution, the shelf 201 is provided with several rectangular slots for hot air to pass through evenly spaced apart. At the same time, the shelf 201 is also provided with bosses 202 in a rectangular array. The top of the bosses 202 is hemispherical, which is used to reduce the contact area between the shelf and the board when the board is placed on the bosses 202.

[0038] The shelf 201 is provided with a front panel 203 and a rear panel 204 at the front and rear respectively, and the front panel 203 is also provided with a front door handle 205 at the front end.

[0039] The front panel 203 is used to block the inlet and outlet 104 when the drying rack 2 is pushed into the drying box 1; the rear panel 204 is used to block the inlet and outlet 104 when the drying rack 2 is pulled out of the drying box 1.

[0040] In this design, optical axes 206 are symmetrically arranged on the left and right sides of the bottom of the shelf 201.

[0041] Specifically, the optical axis 206 is fixedly installed on the bottom of the shelf 201 via the shaft support 207; an open-type linear bearing slider 211 is slidably connected on the optical axis 206, wherein the linear bearing slider 207 is fixedly installed on the side wall of the drying oven 1 via the mounting base 208.

[0042] In this design, extension plates 209 are provided on the left and right rear sides of the rear end of the shelf 201, and an optical axis is also provided below the extension plates 209; a guide plate 210 is also provided between the two extension plates 209; the guide plate 210 is arc-shaped, and the shelf 201, the guide plate 210 and the extension plates 209 are integrally formed, and the tail of the guide plate 210 is bent downward; the guide plate 210 is used to guide the hot air from the bottom of the drying oven 1 to the shelf 201.

[0043] In this design, the lengths of the guide plates 210 on each drying rack 2 are not equal. Specifically, the lengths of the guide plates 210 on each drying rack 2 gradually increase from bottom to top. This arrangement is used to prevent the guide plates 210 on the bottommost layer from directing most of the hot air to the shelf 201 on the bottommost drying rack 2. This is beneficial for each drying rack to receive the hot air output from the hot air assembly 3 evenly.

[0044] When this solution is put into use, the coated and dried board will be prevented on the shelf 201; the hot air assembly 3 will work, the fan 302 will draw in the external airflow, and this airflow will be heated by the electric heating tube 301 and move upward; at this time, the airflow at the front end of the drying chamber 1 will move upward; the airflow at the rear end of the drying chamber 1 will be guided forward and blown onto the board on the shelf 201 when it passes the guide plate 210.

[0045] When the drying oven is closed, the front panel 203 blocks the inlet and outlet 104 to prevent hot air from escaping from the outlet. When it is necessary to remove the board to continue spraying, the shelf 201 of the drying rack 2 can be removed separately. At this time, the rear panel 204 blocks the inlet and outlet 104 to prevent hot air from escaping.
