[0002] In the production of fiberglass products, chopped strand mat (CSM) is an important raw material. Its main function is to serve as a substrate, providing good support and bonding for the fiberglass products.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.
[0038] This application provides an oven device, including a chamber, a mesh belt device, a circulation device, and a heating device. The mesh belt device is located in the middle of the chamber and is used to carry materials. The circulation device includes a circulating air duct and a circulating fan. The air inlet of the circulating air duct is connected to the bottom of the chamber, and the air outlet of the circulating fan is connected to the top of the chamber. The air inlet of the heating device is connected to the air outlet of the circulating air duct, and the air outlet of the heating device is connected to the air inlet of the circulating fan. Through the cooperation of the circulating fan and the circulating air duct, air with a lower temperature at the bottom of the chamber can be drawn in. This air enters the heating device through the circulating air duct, and the heating device raises the temperature. Lower-temperature air is heated to a higher temperature; the heated air enters from the top of the chamber and passes through the material on the mesh belt to heat the material; after heat exchange with the material on the mesh belt, the heated air becomes lower-temperature air at the bottom of the chamber, which can be reheated by a circulation device. In this way, hot air circulation can be achieved inside the chamber, and because the heated air can pass through the material on the mesh belt, both the surface and the interior of the material are heated, which can improve the drying efficiency of the material and reduce the drying energy consumption.
[0039] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.
[0040] like Figures 1-3As shown, an exemplary embodiment of this application provides an oven device, including a chamber 1, a mesh belt device 2, a circulation device 3, and a heating device 4. The mesh belt device 2 is disposed in the middle of the chamber 1 and is used to carry materials. The circulation device 3 includes a circulation duct 31 and a circulation fan 32. The air inlet of the circulation duct 31 is connected to the bottom of the chamber 1, and the air outlet of the circulation fan 32 is connected to the top of the chamber 1. The air inlet of the heating device 4 is connected to the air outlet of the circulation duct 31, and the air outlet of the heating device 4 is connected to the air inlet of the circulation fan 32. The heating device 4 is used to heat the air drawn from the bottom of the chamber 1 by the circulation duct 31, and deliver the heated air to the chamber 1 through the circulation fan 32. The heated air passes through the materials located on the mesh belt device 2 to heat the materials.
[0041] In this embodiment, the circulation fan 32 and the circulation duct 31 work together to draw in cooler air from the bottom of the chamber 1. This air enters the heating device 4 through the circulation duct 31, where it is heated to a higher temperature. The heated air enters from the top of the chamber 1 and passes through the material on the mesh belt 21 to heat the material. After heat exchange with the material on the mesh belt 21, the heated air becomes cooler air again at the bottom of the chamber 1. This air can then be reheated by entering the heating device 4 through the circulation device 3. In this way, hot air circulation can be achieved inside the chamber 1. Since the heated air can pass through the material on the mesh belt 21, both the surface and the interior of the material are heated, which can improve the drying efficiency of the material and reduce drying energy consumption.

The dehumidifier duct 51 may include, for example... Figure 2 The vertical and horizontal air ducts shown are interconnected. The air inlet of the vertical air duct is connected to the top of the housing 1, and the air outlet of the horizontal air duct is connected to the dehumidifier 52.
