Automatic air-locking device for oven width and oven using same

Abstract

The invention discloses an automatic air-locking device for oven width and an oven using the same. The automatic air-locking device is arranged as a full automatic mechanical device; an edge detecting wheel is used for detecting the practical width of the product; the edge detecting wheel is connected with an extend range device; a dragging rack is driven to move by the extend range device, so that a sliding plate connected with a terminal executing mechanism is driven to move along a longitudinal direction; the position and stroke of the edge detecting wheel are equal to the position and stroke of the sliding plate; when a narrow product is detected by the edge detecting wheel, the spare air nozzles on an air spraying box are closed by the sliding plate; when a wide product is detected by the edge detecting wheel, the sliding plate is opened in the same position of the edge detecting wheel, so that the air nozzles on the air spraying box are opened till the width is as same as the width of the wide product and the automatic air-locking purpose is achieved. Thus, the automatic air-locking device provided by the invention has the advantages of automatic air-locking, energy-saving property and capabilities of increasing air pressure and increasing the heat use ratio.

Description

technical field [0001] The invention relates to the technical field of composite material ovens, in particular to an automatic air locking device for oven width and an oven using the same. Background technique [0002] At present, the existing designed non-woven and other composite material drying oven equipment uses air nozzles to blow hot air to the product to dry the product, and the width of the air-jet box in the oven is fixed, but in practice In the production process, the width of the product is determined according to user requirements or process requirements, so the actual product width varies. If the existing non-woven oven is used, when the actual width of the product is smaller than the air jet box in the oven When the width is wide, there will be no product on the air nozzles on both sides of the oven and the heat source will be lost, and it will also cause the hot air pressure to drop, which will affect the penetration of the hot air from the air nozzle to the ...

Problems solved by technology

[0002] At present, the existing design of oven equipment for composite materials such as non-woven fabrics uses air nozzles to blow hot air to the products to dry the products, and the width of the air jet box in the oven is fixed, but in practice In the production process, the width of the product is determined according to the requirements of the user or the process, so the width of the actual product changes. If the existing non-woven fabric oven is used, when the actual width of the product is smaller than the air jet box in the oven When the width is wide, there will be no products on the air nozzles on both sides of the oven and the heat source will be lost, and it will also lead to a drop in hot air pressure, which will affect the penetration of the hot air from the air nozzles to the product, thereby affecting the oven speed and product quality.
