Description

Technical Field

[0001] This utility model relates to the field of surface spraying equipment technology, specifically to a vertical radiant heating oven for baking aluminum profiles. Background Technology

[0002] The aluminum profile spraying production line includes an oven for drying and curing the powder coating on the aluminum profile surface. The conventional design for this oven uses hot air circulation for heating. While this method might be suitable for products in other hardware industries, its application in the powder curing process of an aluminum profile spraying production line presents the following problems:

[0003] 1. Aluminum profiles are long and narrow, and are usually vertically suspended on the hangers of the conveyor line and passed through the curing oven. Therefore, the curing oven is usually as high as 10 meters. In such a tall oven, the heat source is sent in from the bottom and circulates, making it difficult to achieve a uniform temperature at the top, middle and bottom. As a result, aluminum profiles that require a high gloss surface will show obvious color differences in the oven with uneven temperature, which leads to serious quality problems on the surface of the aluminum profiles.

[0004] 2. There are many types of long and narrow aluminum profiles. When encountering aluminum profiles for building materials such as doors and windows, which are thin and lightweight, the circulating air from the heat source rushes into the oven from the bottom when passing through the curing oven. This causes the aluminum profiles passing through the oven to surge and shake. At best, it will damage the surface of the aluminum profiles. At worst, the aluminum profiles will fall and block the conveyor channel, resulting in machine shutdown and production stoppage.

[0005] Therefore, it is necessary to propose a vertical radiant heating oven for aluminum profiles that can bake evenly without causing the aluminum profiles to sway or shake during baking. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and propose a vertical radiant heating oven for aluminum profiles that can bake evenly without causing the aluminum profiles to sway or shake during baking.

[0007] The purpose of this utility model is achieved through the following technical solution: a vertical radiant heating oven for aluminum profiles, comprising an oven body, wherein a U-shaped conveyor chain is provided inside the oven body and communicates with the outside world, wherein multiple workpieces are detachably mounted on the conveyor chain, and wherein multiple baking components are provided inside the oven body located on both sides of the conveyor chain and distributed along the extension direction of the conveyor chain.

[0008] The baking assembly includes a radiant tube, the bottom of which is connected to a burner.

[0009] A reflector is installed on the side of the radiant tube away from the conveyor chain.

[0010] The conveyor chain is equipped with connectors that match the number of workpieces. The connectors have cross grooves, and the cross grooves are detachably connected to a lifting device that is connected to the workpiece.

[0011] The oven body has an inlet and an outlet at one end. The workpiece enters the oven body through the inlet and leaves the oven body through the outlet.

[0012] The oven body includes an outer frame, the inner wall of which is provided with a heat insulation layer, and the heat insulation layer is filled with heat insulation cotton.

[0013] The beneficial effects of this utility model are as follows: Based on the characteristics of aluminum profile products and similar elongated products, an infrared radiation oven is designed. The burner is located at the bottom of the oven body, and the radiation tubes are vertically arranged inside the oven body. The burner burns directly inside the radiation tubes, and the flame directly heats the radiation tubes to 450-550℃. The emitted infrared radiation waves can be absorbed by the powder coating, allowing the workpiece to continuously receive infrared heat energy radiated from all sides. The coating on the workpiece surface can quickly complete the melting, leveling, and curing process. Compared to traditional hot air ovens, this oven has no internal circulating air ducts and no external heating chamber. Ovens using this heating method are smaller, resulting in faster heating, a smaller heat dissipation area, and greater energy efficiency. Inside the oven, apart from the workpiece moving along the conveyor line, there is no circulating air interference. Therefore, the workpiece will not shake due to the circulating air, eliminating quality problems caused by workpiece collisions and shutdowns caused by workpieces falling and jamming the conveyor line. This ensures safety, stability, and reliability. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0020] A vertical radiant heating oven for aluminum profiles, reference Figures 1-3 The oven body 1 includes an inlet 13 and an outlet 14 at its right end, and openings are also present on the top and bottom sides. The oven body 1 includes an outer frame 11, and an insulation layer 12 is provided on the inner wall of the outer frame 11. The insulation layer 12 is filled with insulation cotton.

[0021] The oven body 1 is equipped with a conveyor chain 2 extending to the outside at both ends. The conveyor chain 2 is U-shaped inside the oven body 1, with its two ends extending to the outside at the inlet 13 and outlet 14, respectively. The conveyor chain 2 is moved by a motor connected to the outside. Multiple connectors 21 are evenly arranged on the conveyor chain 2, and each connector 21 has a cross groove 22. The upper side of the lifting device 23 is installed at the cross groove 22 by detachable bolts, and the lower side lifts the aluminum profile workpiece 5.

[0022] Multiple baking components 3 are evenly arranged on both sides of the oven body 1 via the conveyor chain 2. Each baking component 3 includes a radiant tube 31, with a burner 4 located at the lower end of the radiant tube 31. A reflector 32 is located on the side of the radiant tube 31 away from the conveyor chain 2. The radiant tube 31 is arranged vertically.

[0023] After natural gas is introduced into the burner 4, it burns inside the radiant tube 31. The flame and heat released by the combustion are transferred to the radiant tube 31, and then the radiant tube 31 radiates infrared radiation in all directions. The infrared rays radiated toward the workpiece 5 are absorbed by the coating on the surface of the workpiece 5, while the infrared rays radiated toward the reflector 32 are reflected by the reflector 32 and reversed, radiating toward the workpiece 5 again, and are absorbed by the workpiece 5, thereby improving the radiation effect.
