[0002] In the production of agricultural films, the adjustment of the thickness uniformity of the films is usually achieved by manual adjustment or automatic air ring adjustment.
[0003] Through manual sampling and micrometer measurement, the thickness is detected. According to the detection results, the operator adjusts the die gap of the die through the adjustment bolts of the adjustment ring or adjusts the temperature of each zone by dividing the zones of the adjustment ring heater to achieve the purpose of thickness adjustment.
[0004] The working principle of the automatic air temperature or air volume type segmented air ring for agricultural films is to detect the distribution state of the current thickness deviation of the film products in real time through a transverse thickness detection system with a rotating scanning frame installed between the bubble stabilizer and the splint. The detection signal is fed to a computer, and after data processing, adjustment instructions are sent to the respective independent control areas arranged inside the automatic air ring, and different heating or air volume instructions are sent to different areas, so as to achieve the purpose of adjusting the thickness of the film products.
[0005] However, manual adjustment has poor accuracy and low cost. The thickness uniformity of the automatic air temperature or air volume type segmented air ring can be improved by 50% compared with manual adjustment, but due to the too high cost, it cannot be popularized and used on agricultural film equipment.

[0011] As a further improvement of the present utility model, a manual adjustment bolt for adjusting the adjustment ring heater is installed on the mold body.
[0012] As a further improvement of the present utility model, a plurality of the adjustment ring heaters are annularly distributed on the outer side of the mold body.
[0013] Advantages of the present utility model:
