Through above-mentioned design, can guarantee that the upper surface of blowcase 2 can provide the support for the ventilated membrane down, also form the hot air cushion in space on the upper surface of blowcase 2 down simultaneously, all have positive effects to reducing friction and even heating.
Preferably, the extending direction of the wave form surface 22 is consistent with the air intake direction; the cross section areas of the air inlets of the lower blowcase 2 and the upper blowcase 3 are both larger than the cross section area of the air outlet; the diameter of the air blowing hole 17 at the bottom of the upper air blowing box 3 is 1.5 mm-2 mm. The cross section areas of the air inlets of the lower blow box 2 and the upper blow box 3 are larger than the cross section area of the air outlet, and the main purpose is to ensure that after hot air flows into the inner cavity of the blow box, partial hot air is forced to overflow from the air blowing hole 17 and the air exhaust hole 21 by utilizing the flow difference of the hot air, so that the breathable film is uniformly heated.
Preferably, the two cylinders 5 move synchronously. The purpose of the synchronous motion of the air cylinder 5 is to ensure that the upper air blow box 3 and the lower air blow box 2 keep horizontal synchronous motion and stable lifting at any time, and the whole height position of the air blow box can be conveniently adjusted.
Due to the adoption of the technical scheme, the invention has the beneficial effects that:
on the one hand, be provided with lower blowcase 2 and the last blowcase 3 of adjustable height and interval through the inboard at frame 1, be convenient for let hot-blast even blow spill on the ventilated membrane, realize evenly drying, but adopt 5 supports lower blowcase 2 of air cylinder, be convenient for adjust the height of two blowcases, utilize threaded rod 6, spring 8 and nut 7 combination will go up blowcase 3 and fix the top of blowcase 2 under, be convenient for adjust the interval between two blowcases, adjust the interval between ventilated membrane two sides and the blowcase promptly, the whole structure is simple, easy operation, possess stronger adaptability and adjustability, can satisfy the production demand.
On the other hand, through the internal structural design of the air blow box, hot air flowing into the inner cavity of the air blow box can be effectively discharged, and the breathable film is uniformly heated and dried; through the design of post 18 and the smooth spherical head 20 of blowing, not only can reduce the ventilated membrane and blow the case 2 between the friction down, discharge steam to the side through exhaust hole 21 moreover, form the heat air cushion between the clearance of post 18 of blowing, so can be when the ventilated membrane is dried in the heating, can also form the air cushion to the ventilated membrane and support, can avoid blowing up the ventilated membrane that causes perpendicularly and rock and turn over phenomenons such as book even, do benefit to the steady conveying of ventilated membrane and evenly dry.
On the other hand, the temperature sensor 9 is arranged on one of the side boxes 4 and used for detecting the drying temperature in real time, the temperature and humidity sensor is connected with the display 16, the heating temperature can be adjusted by controlling the heating grade of the electric heating pipe 11, the numerical control function is realized, the drying temperature can be adjusted in time, convenience and rapidness in adjustment are realized, the production efficiency can be effectively improved, and the device has good practical value and popularization value.
Specific example 2, as shown in fig. 1-6:
in this embodiment, the operation steps of the assembly line for processing the breathable film by numerical control are as follows:
the method comprises the following steps: firstly, erect frame 1 on the ventilated membrane transfer line, let the ventilated membrane pass between lower blowcase 2 and the last blowcase 3, be convenient for dry the both sides of ventilated membrane, then open electric heating pipe 11, let it generate heat, then open air-blower 15, send into the air in the air guide pipe 12, the heat that this moment electric heating pipe 11 sent can heat the air in the air guide pipe 12, the hot-air is through tee bend 13 again, hose 14 and side case 4 enter into in lower blowcase 2 and the last blowcase 3, the hot-air is blown out by blow hole 17 and the exhaust hole 21 on the blowcase at last, thereby last, even blowing is on the both sides of ventilated membrane.
Step two: observe the temperature value that shows on the display 16, but because the temperature in the real-time detection frame 1 of temperature sensor 9, will detect numerical value again and transmit for display 16, therefore, only need can know the stoving temperature through observing display 16, when the stoving temperature is too high, can reduce electric heating pipe 11's heating grade, when the stoving temperature is crossed lowly, can increase electric heating pipe 11's heating grade, so that the constant temperature is dried, adopt the numerical control to control, be favorable to in time adjusting the stoving temperature, and adjust convenient and fast, can effectively improve production efficiency.
Step three: the conveying equipment of the breathable film is started, the breathable film is conveyed between the lower blowcase 2 and the upper blowcase 3 by the breathable film, hot air can be uniform, and the breathable film is continuously blown on two sides of the breathable film, so that drying operation is carried out.
Step four: when the height of the air outlet box needs to be adjusted, the air cylinder 5 can be opened to drive the two air blowing boxes to lift, thereby the height can be adjusted quickly, when the distance between the lower air blowing box 2 and the upper air blowing box 3 needs to be reduced, the nut 7 is rotated downwards, the compression spring 8 is used, the nut 7 is used for pressing the upper air blowing box 3 to descend, thereby the distance between the lower air blowing box 2 and the upper air blowing box 3 is reduced, when the distance between the lower air blowing box 2 and the upper air blowing box 3 needs to be increased, the nut 7 is rotated upwards, the spring 8 is used for pushing the upper air blowing box 3 upwards, thereby the distance between the lower air blowing box 2 and the upper air blowing box 3 is increased, the distances between the lower air blowing box 2 and the upper air blowing box 3 and the breathable film can be adjusted conveniently according to requirements, the drying speed can be adjusted conveniently, the whole structure is simple, the operation is easy, strong adaptability and adjustability are achieved, and the production requirements can be met.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and shall cover the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
