Embodiment Construction
[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0024] Traditionally, since the process temperature of each oven unit usually has a difference of more than 5°C, the temperature of the fresh air introduced into the fresh air main pipe is usually heated to a preset temperature, which must form a temperature difference with the environment...

The invention relates to a film production line and a ventilating distributing oven. The ventilating distributing oven comprises an oven unit, a fresh air mother tube, fresh air branch tubes, a wastedischarging mother tube and waste discharging branch tubes, wherein the fresh air mother tube and the waste discharging mother tube are positioned outside the oven unit; the fresh air mother tube andthe waste discharging mother tube do not cause influences on an inner environment of the oven unit, so that temperature consistency and stability of a film area can be conveniently guaranteed, the temperature of the film area can be more precisely controlled, and film product quality is guaranteed. Besides, the waste discharging branch tubes sleeve outside the fresh air branch tubes, and the tubewall temperature of the waste discharging branch tubes is closer to a process temperature of the oven unit, so that on one hand, the waste discharging branch tubes can prevent the tube wall temperatures of the fresh air branch tubes from affecting interior environment of the oven unit, on the other hand, high-temperature waste gas in the waste discharging branch tubes exchanges heat with the freshair branch tubes, and therefore, the fresh air temperature of the fresh air branch tubes can be increased, and waste gas energy of the waste discharging branch tubes is sufficiently utilized.
Description
technical field [0001] The invention relates to the technical field of film stretching treatment, in particular to a film production line and a ventilation distribution oven. Background technique [0002] The ventilation distribution oven is used to provide suitable process conditions for the polymer film, so that it can complete stretching, heat setting, cooling and other processing processes in a high temperature environment. Among them, the polymer film material will release low-component volatiles to varying degrees when heated, and these volatiles will condense and adhere to the oven in a relatively low temperature environment, especially on the surface of the film, which seriously affects the film. product quality. For example, for the production of membrane materials used in special high-end fields, such as lithium batteries, electronics, medical treatment, and aerospace, there are extremely strict requirements on the uniformity of hot air temperature, wind speed, an...
