Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of adhesive film manufacturing, and more particularly to an adhesive film extruder. BACKGROUND

[0002] With the rapid development of material processing technology, the bubble problem in adhesive film production has become a key factor restricting the development of the industry. At present, although the traditional adhesive film extruder can produce in a high-temperature environment to a certain extent to reduce the moisture in the raw materials, the raw materials are still prone to moisture, resulting in many bubbles in the produced adhesive film products. For example, in the plum rain season in the south, the walls and floors can sweep out water, and even after high-temperature treatment, the raw materials still carry a large amount of moisture, resulting in frequent bubbles in the produced adhesive film products, and the yield is obviously decreased. This not only affects the quality of the products and the economic benefits of the enterprise, but also limits the wide application of the adhesive film extruder in humid environments. Therefore, it is necessary to develop an adhesive film extruder that can adapt to humid environments and effectively reduce the moisture of raw materials. CONTENT OF THE UTILITY MODEL

The material receiving hopper comprises an inner wall and an outer wall, and a gap is formed between the inner wall and the outer wall. An air inlet and an air outlet are provided on the material receiving hopper and communicate with the gap. The air guide device is installed on the air inlet and / or the air outlet, and the air guide device is used to guide the outside air into / out of the gap.

This kind of combination can also achieve similar effects, and the present application will not be described here.

[0027] In one example, the outer wall 22 is provided with a transparent observation window 226 for observing the internal condition of the material receiving hopper 20. Specifically, the outer wall 22 is provided with an observation port penetrating the inner wall 21, and the observation port is mounted with a transparent material (such as glass, high-temperature-resistant transparent plastic plate), and the amount of raw materials in the inner cavity can be observed through the transparent observation window 226.

[0028] The wind guide device 30 comprises a wind guide fan 31, an air purifier 32 and a connecting pipe 33, the wind guide fan 31 and the air purifier 32 are respectively mounted at two ends of the connecting pipe 33, one end of the connecting pipe 33 is mounted on the air inlet 222 or the air outlet 223, and the rotation direction of the wind guide fan 31 is changed to change the wind guide device 30 for air intake or air outlet.

The air outlet 223 at the upper end of the receiving hopper 20 guides the steam in the inner cavity to the outside under the action of the air guide device 30, and also guides the gas in the gap 23 between the inner wall 21 and the outer wall 22 to the outside, so that the gas in the gap 23 flows, which is convenient for continuously heating the inner wall 21.
