Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to an oven, an oven component and a primer. Background Art

[0002] Coating machines are mainly used for surface coating of substrates such as electrodes, films, and paper. Specifically, a layer of glue, coating, or ink with specific functions is applied to the rolled substrate, and then the rolled substrate is dried and rolled up. Before coating, in order to ensure the surface quality of the film product, it needs to be pre-dried. Existing coating machines dry the substrate in an oven.

[0003] Existing oven 10 components such as Figure 1 As shown, it includes an oven 101, a main transmission, an exhaust duct 109, a fresh air duct 107, a return air duct 108, a circulating fan 106, a circulating air duct 103, a heating package 105, a filter 104, an air inlet duct 102, a damper and a mounting plate 110. The direction of the exhaust fluid is: circulating fan 106 → circulating air duct 103 → heating package 105 → filter 104 → air inlet duct 102 → oven 101 → return air duct 108 → circulating air duct 103 → (part of the air) exhaust duct 109. However, because all damper actuators are placed on the operating side, in order to avoid interference with the damper rod 111, the design height of the damper rod 111 needs to exceed the oven 10, so it is necessary to independently design the exhaust damper duct adapter to make the exhaust damper rod 111 higher than the oven 10. This will result in the overall height of the equipment being unable to be lowered, and therefore cannot meet the height limit requirements of the customer's factory building; and the maintenance space is small and can only be entered through the gap in the air duct to inspect and replace the belt, and it is not easy to find abnormal equipment operation problems during inspections.
