Description

Technical Field

[0001] The utility model relates to the technical field of infrared ovens, in particular to an adjustable infrared oven. Background Art

[0002] In recent years, with the rapid development of my country's general industry and automobile industry, various forms of spray drying furnaces have increased rapidly, and the application of drying furnace technology has become increasingly modernized. Since the sprayed workpiece needs to be baked at a certain temperature for a certain period of time to meet the requirements of paint, drying furnaces are widely used in modern coating production lines, and the demand is gradually increasing.

[0003] With the diversification of market demand, the size of products in the same production line varies greatly. In existing drying furnace equipment, the heat source is fixed, which cannot meet the drying needs of workpieces with large size changes, resulting in inconsistent workpiece drying effects. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an adjustable infrared baking oven to address the deficiencies of the prior art, which effectively solves the problem of poor baking caused by the distance between the radiation plate and the workpiece being too far or too close when baking workpieces of different sizes.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An adjustable infrared oven comprises a drying chamber and a gas valve group. A feed inlet and a discharge outlet are respectively provided at the front and rear of the drying chamber. Two movable brackets are symmetrically arranged in the drying chamber. A plurality of gas radiation heating plates are arranged on opposite sides of the two movable brackets. Each gas radiation heating plate is individually connected to the gas valve group.

[0007] Furthermore, the gas radiation heating panels are arranged in a rectangular array on opposite sides of the two movable brackets.

[0008] Furthermore, the opposite surfaces of the two movable brackets are covered with infrared reflection layers.

[0009] Furthermore, electric double doors are provided at the feed inlet and the discharge outlet.

[0010] Furthermore, a gas leak detector is provided in the drying chamber.

[0011] The beneficial effects of the utility model are:

[0012] The utility model installs the gas radiation heating plate on two relatively movable brackets, and adjusts the movable bracket carrying the gas radiation plate to a suitable position according to the size of the workpiece, thereby ensuring that the distance between the gas radiation plate and the workpiece remains unchanged, and effectively solves the problem of poor baking caused by the distance between the radiation plate and the workpiece being too far or too close when baking workpieces of different sizes.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] Reference Figure 1-Figure 3 The utility model provides an adjustable infrared oven, comprising a drying chamber 1 and a gas valve group 2. The drying chamber 1 is provided with a heat preservation layer on the outside, and the joints are sealed with sealing strips. Gas is provided to the oven through the gas valve group 2. A feed port 101 and a discharge port 102 are respectively provided at the front and rear of the drying chamber 1. The workpiece 11 enters the drying chamber 1 from the feed port 101 through a conveying mechanism, and then is sent out from the discharge port 102 to complete the drying process. Electric double-opening doors 6 are provided at the feed port 101 and the discharge port 102 to reduce heat loss in the oven.

[0019] Two movable brackets 3 are symmetrically arranged in the drying chamber 1, and a plurality of gas radiation heating plates 4 are arranged on the opposite sides of the two movable brackets 3. According to the size of the workpiece 11, the movable bracket 3 carrying the gas radiation plate 4 is adjusted to a suitable position to ensure that the distance between the gas radiation plate 4 and the workpiece remains unchanged, which effectively solves the problem of poor baking caused by the distance between the radiation plate and the workpiece being too far or too close when baking workpieces of different sizes. The gas radiation heating plate 4 provides heat for drying the workpiece 11, and each gas radiation heating plate 4 is individually connected to the gas valve group 2, and the gas is transported to each gas radiation heating plate 4 through the gas valve group 2.

[0020] The gas radiation heating plates 4 are arranged in a rectangular array on the opposite sides of the two movable brackets 3, which is convenient for adjusting the drying area. According to the size of the workpiece 11, only the gas radiation heating plates 4 close to the workpiece 11 are connected, and the redundant gas radiation heating plates 4 are turned off to reduce heat waste. The opposite sides of the two movable brackets 3 are covered with infrared reflection layers 5 to increase the infrared refractive index.

[0021] A gas leak detector 7 is provided in the drying chamber 1 to ensure the safety of gas use. A circulating air system can also be added to the drying chamber 1 to ensure uniform heat flow in the drying chamber 1 during the heating process of the workpiece 11, which is conducive to improving the appearance quality of the workpiece paint surface.

[0022] During operation, the conveyor chain 10 is used to convey the workpiece 11 to the feed port 101. According to the size of the workpiece 11, the movable bracket 3 carrying the gas radiation plate 4 is adjusted to a suitable position, and then the workpiece 11 is sent into the drying chamber 1 so that the workpiece 11 is located between the two movable brackets 3, so that the gas radiation heating plate 4 is continuously heated to dry the workpiece 11.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
