[0021] With reference to Figure 1 The utility model provides a membrane material roll curing chamber, including casing 100, support 200, centrifugal fan 300 and air scoop 400, the inside of casing 100 has the cavity 101 of accommodating membrane material 500.Support 200 is connected to casing 100 and is located in the cavity 101, and support 200 is used for supporting the membrane material 500 placed.Centrifugal fan 300 is connected to casing 100, and is located above support 200, and the lower side of centrifugal fan 300 is provided with electric heating plate 310, and electric heating plate 310 is connected to the top of support 200, and is used for heating the airflow of centrifugal fan 300 blowing.Air scoop 400 is connected to casing 100, and air scoop 400 is arranged around centrifugal fan 300, and air scoop 400 includes screen 410 and suction plate 420 connected to the lower side of screen 410, and suction plate 420 is inclinedly arranged from screen 410 to the outside downward to guide airflow to pass through screen 410, and the upper side of screen 410 is provided with air deflector 430, and air deflector 430 is inclinedly arranged from screen 410 to the outside upward to guide the airflow generated by centrifugal fan 300 to be quickly distributed in the cavity 101.

[0022] In a specific embodiment, the shell 100 serves as the main structure of the curing chamber, with a cavity 101 formed inside for accommodating the film material 500 to be cured. The support 200 is connected to the inside of the shell 100 and located within the cavity 101, for supporting and placing the film material 500. The centrifugal fan 300 is connected to the shell 100 and located above the support 200. The centrifugal fan 300 functions to blow heated air into every corner of the curing chamber, promoting uniform heat distribution. The electric heating plate 310 is connected to the top of the support 200, below the centrifugal fan 300. The electric heating plate 310 is used to heat the airflow blown by the centrifugal fan 300, and by adjusting the power of the electric heating plate 310, the temperature inside the curing chamber can be controlled. The air guide cover 400 is connected to the shell 100 and arranged around the centrifugal fan 300. The air guide cover 400 includes a screen 410 and an air suction plate 420 connected to the lower side of the screen 410. The air suction plate 420 is inclined downward and outward from the screen 410, which can effectively guide the airflow to pass through the screen 410 and avoid direct impact on the film material 500 causing local overheating. The upper side of the screen 410 is provided with an air guide plate 430, which is inclined upward and outward from the screen 410, which can guide the airflow generated by the centrifugal fan 300 to quickly cover the entire cavity 101, ensuring that each part of the film material 500 can be fully heated. Through the combined use of the centrifugal fan 300 and the electric heating plate 310, the heating and uniform distribution of airflow are achieved, effectively solving the problem of uneven heating of the film material 500 in traditional curing chambers. The inclined arrangement of the air suction plate 420 and the air guide plate 430 of the air guide cover 400 further optimizes the airflow path, improves the heat transfer efficiency, and at the same time avoids the occurrence of local overheating, which is suitable for the curing process of various film materials 500, and can significantly improve product quality and production efficiency.

[0023] Specifically, the support 200 is a key component for supporting the film material 500, and its structural stability directly affects the uniform heating of the film material 500 during the curing process. In this embodiment, the support 200 includes two vertical rods 210 arranged parallel to each other and opposite to each other, which are vertically installed on the bottom or side of the shell 100, ensuring the stability of the support 200. Connected to the top of the vertical rod 210 is a horizontal rod 220, which extends horizontally along the top of the vertical rod 210 to form a stable support platform. The electric heating plate 310 is connected to the top of the horizontal rod 220, and the heat is uniformly transmitted to the entire curing chamber through the horizontal rod 220.

[0024] In order to more conveniently support and fix the roll of film material 500, two vertical rods 210 are symmetrically arranged with bases 211 at opposite positions. A fixed shaft 212 is horizontally arranged between the two bases 211, and the fixed shaft 212 serves to support the roll of film material 500, so that the roll of film material 500 can be kept flat and stable during the curing process. Optionally, the fixed shaft 212 can be adjusted according to the width and weight of the film material 500, so as to ensure the best supporting effect.

[0025] The electric heating plate 310 serves as a heating element, and its performance directly affects the temperature distribution and heating efficiency in the curing chamber. In the embodiment, the electric heating plate 310 adopts a flat plate 110 type ceramic infrared radiation heating body. The heating body has the advantages of fast heating speed, high thermal efficiency and uniform radiation, and can rapidly transfer heat to the film material 500 while reducing energy loss.

[0026] It should be noted that the shell 100 serves as the main structure of the curing chamber, and the selection of the material and the design of the structure are crucial to the heat preservation performance and stability. In the embodiment, the shell 100 is composed of a rectangular shell 100 composed of a plurality of flat plates 110, and the flat plates 110 adopt polyurethane foam sandwich color steel plates. The polyurethane foam sandwich layer has good heat preservation performance and can effectively reduce heat loss, and the color steel plate provides sufficient strength and durability.

[0027] It should be noted that the bottom plate 120 of the shell 100 is connected to the flat plates 110 on the side of the shell 100 by a combined broken bridge lap joint. This connection mode effectively blocks the heat transfer path by arranging a broken bridge structure between the bottom plate 120 and the side plate, thereby reducing heat loss. At the same time, the combined design makes installation and disassembly more convenient, which is beneficial to the maintenance and upgrading of the equipment.

[0028] In order to further improve the heat preservation performance in the curing chamber, the bottom plate 120 of the shell 100 is provided with a heat insulation filling layer 130. The heat insulation filling layer 130 is located in the cavity 101 and can effectively block the heat transfer path from the bottom plate 120 to the ground. The heat insulation filling layer 130 can be made of various materials, such as rock wool, glass wool, etc., which all have good heat preservation performance.

[0029] The above describes the embodiments of the utility model in combination with the drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the utility model.
