Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-4 As shown, the present invention proposes an aluminum rod spraying and curing device, which includes a drying box 1 and a door 2 hinged to the front side of the drying box 1. The inner side of the drying box 1 is provided with a placement component 3 for placing aluminum rods.

[0022] In this invention, the placement component 3 can hang the aluminum rods in a conical shape, and at the same time, it can separate and protect the two aluminum rods hanging together to prevent them from colliding.

[0023] It should be noted that the upper surface of the drying chamber 1 is connected to two sets of exhaust vents 6, and each exhaust vent 6 is equipped with a one-way valve. The inner wall of the drying chamber 1 and the side of the door 2 near the drying chamber 1 are lined with aluminum silicate fiber. The hot air overflowing from the drying chamber 1 is discharged through the exhaust vents 6 in conjunction with the one-way valve, and the supply of hot air is stopped. The one-way valve is in the closed state, which can prevent heat diffusion and keep the drying chamber 1 warm.

[0024] In an optional embodiment, the placement component 3 includes a support plate 31 slidably connected to the bottom wall of the drying oven 1. Two support frames 32 are fixedly connected to the lower surface of the support plate 31 and penetrate the bottom wall of the drying oven 1. The inner side of each support frame 32 is rotatably connected to a rotating shaft 33 that penetrates the support plate 31. One end of each rotating shaft 33 that penetrates the support plate 31 is fixedly connected to a support column 37. A motor 34 is fixedly installed on the lower surface of the left support frame 32, and the output shaft of the motor 34 is fixed to the lower end of the left rotating shaft 33. Several sets of support rods 38 are fixedly connected to the outer side of the support column 37, and a hook 39 is installed on the end of each support rod 38 away from the support column 37. Several annularly distributed protective blocks 310 are fixedly connected to the outer side of the support column 37, and each protective block 310 is located between two support rods 38. A fixing plate 313 is fixedly connected to the middle of the upper surface of the support plate 31, and a hydraulic rod 314 is fixedly connected to the back of the drying box 1. The output end of the hydraulic rod 314 passes through the drying box 1 and is fixed to the fixing plate 313. Transmission components 35 for transmission are provided on the two rotating shafts 33.

[0025] It should be noted that the support column 37 is a cone shape that is wider at the top and narrower at the bottom. Several sets of support rods 38 are distributed at equal intervals from top to bottom on the support column 37, and each set of support rods 38 is distributed in a ring at equal intervals. The length of each set of support rods 38 decreases from top to bottom, so that each set of aluminum rods can be staggered and distributed in a staggered manner, thereby avoiding collisions between the upper and lower sets of aluminum rods during the curing process. Ventilation chambers 4 are fixedly connected to the left and right side walls of the inner cavity of the drying oven 1, and air outlets 5 are provided on the ventilation chambers 4. A heating element 7 is provided on the back of the drying oven 1 to deliver hot air into the ventilation chambers 4.

[0026] In this embodiment, the conical support column 37, together with the support rods 38 whose length decreases from top to bottom, allows each set of aluminum rods to be staggered. The protective block 310 located between the two support rods 38 can flexibly block the two adjacent aluminum rods, thereby preventing the aluminum rods from colliding and scratching the surface coating during the rotation, drying and curing process, thus improving the curing effect of the aluminum rods.

[0027] The protective block 310 is long and narrow, and is made of high-temperature resistant silicone. The surface of the hook 39 is covered with a high-temperature resistant rubber sleeve, so that when the aluminum rod stops and shakes, it can touch the protective block 310 to protect the outer surface of the aluminum rod and prevent it from colliding with each other. This improves the damping of the aluminum rod when it is hung on the hook 39, thereby reducing the shaking amplitude of the aluminum rod after the hook 39 stops.

[0028] In addition, several annularly distributed ball bearings 311 are rotatably connected to the surfaces of both the upper and lower ends of the support column 37 to improve the stability of the axial rotation and horizontal forward and backward movement of the support column 37. A receiving tray 312 located at the lower end of the support column 37 is placed on the support plate 31. Each receiving tray 312 consists of two semi-circular discs, and the upper surface of each pair of semi-circular discs is fixed to the outer surface of the lower end of the support column 37 by bolts. The receiving tray 312 is used to collect dripping paint, such as aluminum rods treated by electrophoresis and anodizing.

[0029] Secondly, a set of sliders 36 are fixedly connected to the lower surface of the support plate 31, and a sliding groove is provided on the inner bottom wall of the drying box 1 for the sliders 36 to slide. By the sliding limit of the sliders 36 in conjunction with the sliding groove, the support plate 31 can slide stably and horizontally on the inner bottom wall of the drying box 1. A rectangular hole is provided on the inner bottom wall of the drying box 1 for the support frame 32 to slide, so that the support frame 32 that penetrates the inner bottom wall of the drying box 1 has a diameter for moving back and forth.

[0030] Furthermore, the transmission assembly 35 consists of two pulleys and a transmission belt. The two pulleys are symmetrically fixedly connected to the two rotating shafts 33, and the transmission belt is sleeved on the two pulleys, so that the left rotating shaft 33 driven by the motor 34 can drive the right rotating shaft 33 to rotate synchronously through the transmission pulley and the transmission belt, thereby driving the two support columns 37 to rotate synchronously.

[0031] In an optional embodiment, the heating element 7 includes a mounting chamber 71 fixedly connected to the back of the drying chamber 1 and located above the hydraulic rod 314. A plurality of heating tubes 74 are installed on the inner wall of the mounting chamber 71. A mounting cylinder 72 is fixedly connected to the back of the drying chamber 1, and a fan 73 is fixedly installed on the inner side of the mounting cylinder 72. An air supply pipe 75 with one end penetrating through the inner wall of the drying chamber 1 is connected to both the left and right sides of the mounting chamber 71. One end of the air supply pipe 75 penetrating through the drying chamber 1 is connected to the ventilation chamber 4.

[0032] In this embodiment, the fan 73, when activated, heats the blown air in conjunction with the heating tube 74. The hot air is then delivered to the ventilation chamber 4 through two air supply pipes 75 and blown out through the air outlet 5 on the ventilation chamber 4 to heat and solidify the aluminum rods in the drying oven 1.

[0033] It should be noted that there are several air outlets 5, and the upper part of the ventilation chamber 4 is inclined. Several air outlets 5 are equidistantly distributed on the side of the ventilation chamber 4 away from the inner wall of the drying box 1 and on its upper part, so that the hot air delivered into the ventilation chamber 4 can be blown horizontally and obliquely through the air outlets 5 on the ventilation chamber 4 to the aluminum rods hanging on the support column 37 for uniform heating and curing.

[0034] The working principle in the above embodiments is as follows: Because the support column 37 is conical and the lengths of the several sets of support rods 38 fixed on the support column 37 decrease sequentially from top to bottom, when the aluminum rod is placed on the hook 39 through the hanging hole at its end, the two aluminum rods can be staggered in front and behind. Therefore, after the fan 73 is started and the heating tube 74 is turned on to heat the blown air, the hot air is delivered to the ventilation chamber 4 through the two air supply pipes 75 and then blown out through the air outlet 5 on the ventilation chamber 4. The motor 34 then starts to drive the left rotating shaft 33 to rotate, and then drives the right rotating shaft 33 to rotate synchronously through the transmission component 35. After the two support columns 37 rotate synchronously, hot air can be blown to heat and cure the aluminum rods hanging in the drying box 1. The protective block 310 located between the two support rods 38 can flexibly block the two adjacent aluminum rods, thereby preventing the aluminum rods from colliding and scratching the surface coating during the rotation drying and curing process, which is beneficial to the curing effect of the aluminum rod surface coating. Because the upper and lower aluminum rods are staggered, during the rotation, drying and curing process, the coating on the upper aluminum rod is prevented from dripping onto the lower aluminum rod. At the same time, the dripping coating can be collected by the receiving tray 312.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
