Embodiment Construction

[0009] The invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0010] As shown in the figure, the automatic width controller for agricultural film production of the invention mainly includes a switch box 1, a test board 2, and a controller 3. It is characterized in that there are symmetrical rails 4 on the upper and lower walls of the switch box 1, and there are additional valve scales at both ends of the rails. Control the conductive contact block 11, lower the valve scale to control the conductive contact block 12, and there is a conductive slider 5 in the middle; the conductive slider 5 is connected by a conductor 6, and an insulator 7 is arranged outside the conductor 6; the middle of the insulator 7 and the test The plate 2 is connected with the connecting rod 9, and a spring 8 is arranged between the insulator 7 and the right wall of the switch; the valve scale control contact block 11 is increased, and the ...

Abstract

The invention relates to an automatic breadth controller for agricultural film production. The automatic breadth controller mainly comprises a switch box, a test board and a controller body. By means of the automatic breadth controller, the problems that in the existing thin film production process, the breadth of a thin film can not be measured dynamically and automatically and controlled in real time, the product quality can not be ensured, too much manpower is used for finished product measurement, the one-by-one measurement process is tedious, and the measurement accuracy is low are solved.

Description

technical field [0001] The invention is an automatic controller, specifically a device for automatically controlling width in the production of agricultural film. Background technique [0002] Agricultural film is an important means of production in my country's modern agricultural production. It is the fourth largest agricultural production material after seeds, chemical fertilizers and pesticides. It has become an indispensable condition for agricultural production. The demand for agricultural film is increasing year by year, and the production technology of agricultural film is also improving. Soon, great progress has been made in raw materials, additives, equipment, processing technology, testing technology, etc. However, there is no systematic automatic control system in the production process of agricultural film. It is basically a combination of traditional and modern production methods. It is decided to reduce or increase the valve opening parameter to control the wi...
