Problems solved by technology
[0003] When the mold is heated by rotating in the oven, heat will be continuously generated in the oven, so that the air pressure in the oven will continue to rise. If the internal air pressure is too high and the external environment of the oven will form a large air pressure difference, the walls around the oven will be greatly affected by The gas pressure generated by the air pressure difference, and at the same time, the high air pressure will cause most of the heat to be discharged from the box wall, which will cause damage to the box wall
In order to solve the above problems, in the prior art, there is an air outlet on the upper surface of the oven, but there are still some problems: the air outlet cannot adjust the exhaust air volume, and the air pressure in the oven cannot be adjusted in a timely and reasonable manner, resulting in air pressure in the oven will be uneven

Embodiment Construction
[0024] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0025] Such as figure 1 , 2 , 3 and 6, the regulating device used to adjust the air pressure in the rotomolding oven includes an oven 1, a fan, an air guide pipe 4 and an exhaust hood 5, and the upper end of the oven 1 is provided with an exhaust port 1a, and the exhaust The opening 1a is square, and the air outlet frame 1b is installed at the air outlet 1a. The air outlet frame 1b is square and has convex edges extending outward from the upper and lower ports. The convex edges of the upper and lower ports are respectively fixed and installed on the oven at the air outlet 1a. 1 On the upper and lower sides of the upper end wall, the air outlet frame 1b is designed to protect and strengthen the air outlet 1a. The upper en...

The invention provides an adjusting device for adjusting air pressure in a rotational moulding oven, and belongs to the technical field of rotational moulding. The adjusting device solves the problem that the wind exhausting quantity of wind exhausting openings in existing ovens is not adjustable. The adjusting device for adjusting the air pressure in the rotational moulding oven comprises an oven, a wind exhausting opening formed in the upper end part of the oven, a fan and a wind exhausting cover. The fan comprises a motor, a fan cover, an inner cavity formed in the fan cover and a blade installed in the inner cavity. The fan cover is provided with a wind inlet and a wind outlet. The wind exhausting cover is provided with a ventilation pipeline. One end of the ventilation pipeline communicates with the wind exhausting opening, and the other end of the ventilation pipeline communicates with the wind inlet. An adjusting structure which can adjust the ventilation quantity of the ventilation pipeline is arranged on a ventilation cover. The adjusting device for adjusting the air pressure in the rotational moulding oven has the advantages that the wind exhausting quantity of the adjusting device is adjustable, and the uniform and stable air pressure in the oven is ensured.
Description
technical field [0001] The invention belongs to the technical field of rotational molding, and relates to an adjusting device for adjusting the air pressure in a rotational molding oven. Background technique [0002] Rotational molding, also known as rotational molding, rotary molding, rotary molding, etc., is a hollow molding method for thermoplastics. The method is to add plastic raw materials into the mold first, and then put the mold in an oven to continuously rotate along two vertical axes and heat it. Attached to the entire surface of the mold cavity, shaped into the desired shape, and then cooled and shaped to form a product. [0003] When the mold is heated by rotating in the oven, heat will be continuously generated in the oven, so that the air pressure in the oven will continue to rise. If the internal air pressure is too high and the external environment of the oven will form a large air pressure difference, the walls around the oven will be greatly affected by ...
