The utility model discloses simple structure, the simple operation is transformed into hole and interval for 1 cm's wind gap with slit type wind gap, and the effectual heating efficiency that has improved and the face is heated more evenly, has effectually improved the tensile inhomogeneous condition of polyester film, has guaranteed polyester film's production quality, is favorable to guaranteeing polyester film's production efficiency and benefit, is favorable to the long-term development of enterprise.
Description
Technical Field
The utility model belongs to the technical field of the polyester film production, concretely relates to high-efficient heating wind gap device of production polyester film.
Background
In the production process of the polyester film, transverse stretching is the second-step stretching in the biaxial stretching process, transverse stretching equipment is a set of oven heating stretching equipment, and after the polyester film is heated by blowing air up and down, the polyester film is tightly clamped by metal clips on two sides to be stretched towards two sides. The inside of the oven is divided into 4 areas, namely a preheating area, a stretching area, a heat setting area and a cooling area, wherein the heat setting area has the function that the film is processed or applied at a higher temperature and has better dimensional stability, and the heat setting effect is characterized by the heat resistance index-high temperature heat shrinkage rate of the film: heating at 150 ℃ for 30min, wherein the shrinkage percentage of the brightened polyester film is generally controlled below 1.0%, a slit-type air port is adopted as an air port of a heat setting area, a stainless steel plate is adopted on the surface of the air port to cover a reserved hole, the hole is 9CM, the space between the holes is 9CM, the air port device is not uniformly heated, the heating efficiency is poor, the condition that the polyester film is not uniformly stretched is directly caused, the quality of the polyester film is directly influenced, and the production efficiency and the benefit are reduced.
Disclosure of Invention
The utility model aims at solving the above defects and providing a high-efficiency heating tuyere device for producing polyester film.
In order to overcome the defect that exists among the background art, the utility model provides a technical scheme that its technical problem adopted is: the utility model provides a production polyester film's high-efficient heating wind gap device, includes wind gap baffle and wind gap, the wind gap sets up in the front side of wind gap baffle, and divide into two-layer about.
In a preferred embodiment of the present invention, the size of the tuyere is a square of 1cm, and the number of the tuyere is 15 to 25. The air outlet of the air port is more uniform, and the heating effect is better.
In a preferred embodiment of the present invention, the gap between adjacent tuyeres is 1 cm. The air outlet quantity of the adjacent air ports is ensured to be the same.
The utility model has the advantages that: simple structure, the simple operation is transformed into the wind gap that hole and interval are 1cm with slit type wind gap, and effectual heating efficiency that has improved and the face is heated more evenly, has effectually improved the tensile inhomogeneous condition of polyester film, has guaranteed polyester film's production quality, is favorable to guaranteeing polyester film's production efficiency and benefit, is favorable to the long-term development of enterprise.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
As shown in figure 1, the high-efficiency heating tuyere device for producing the polyester film comprises a tuyere baffle 1 and a tuyere 2, wherein the tuyere 2 is arranged at the front side of the tuyere baffle 1 and is divided into an upper layer and a lower layer.
In a preferred embodiment of the present invention, the tuyere 2 has a size of 1cm square, and the number is 15 to 25. The air outlet of the air port 2 is more uniform, and the heating effect is better.
In a preferred embodiment of the present invention, the gap between adjacent tuyeres 2 is 1 cm. The air outlet quantity of the adjacent air ports is ensured to be the same.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
