Embodiment Construction
[0009] The rapid prototyping method of drip irrigation belt is as follows: figure 1 shown. The drip irrigation tape blank 1 in a high temperature state is sent to the roll forming die 2 continuously from top to bottom. The rolling forming die 2 rotates at a high speed, and with the cooperation of the roller 3, the drip irrigation tape blank 1 is continuously rolled out on the uncooled drip irrigation tape blank to form a drip irrigation tape 4. The roller 3 can be either an ultrasonic welding head or a thermocompression welding head. The formed drip irrigation belt 4 is pulled to the next process by a traction mechanism composed of guide rollers 5, 9, etc. The feature of the inventive method is that after the drip irrigation tape 4 is molded and before the drip irrigation tape leaves the rolling forming mold 2, the cooling liquid is used to cool the drip irrigation tape adsorbed on the rolling forming mold. figure 1 The figure shows that when the drip irrigation belt 4 runs...

A rapid forming method for drip irrigation tape, which continuously sends the drip irrigation tape blank in high temperature state to the rolling forming mold, and the rolling forming mold continuously rolls out the drip channel on the uncooled drip irrigation tape blank, and makes it The drip irrigation tape blank is formed into a tube-shaped drip irrigation tape. Its main feature is that after the drip irrigation tape is formed and before the drip irrigation tape leaves the rolling forming mold, the drip irrigation tape adsorbed on the rolling forming mold is started to be treated with cooling liquid. Allow to cool. The invention enables the drip irrigation belt to have a certain anti-deformation ability when it leaves the rolling forming mold, so that the traction speed of the drip irrigation belt can be accelerated, and the forming speed of the drip irrigation belt can be improved. In order to realize the above method, the present invention also provides a drip irrigation tape forming machine, its main feature is that a container with a built-in cooling liquid is arranged under the rolling forming mold, and the rolling forming mold part is immersed in the cooling liquid, so that the drip irrigation tape is The roll forming dies are immersed in cooling fluid prior to forming.
Description
technical field [0001] The invention relates to a forming method and forming equipment of a drip irrigation belt for agricultural irrigation. Background technique [0002] The surface of the drip irrigation belt has many tortuous drip channels arranged at intervals along the length direction. In order to form the drip flow channel on the drip irrigation belt blank, and make the drip irrigation belt blank into a drip irrigation belt, at present, the rolling method is used to allow the rolling forming mold to continuously roll and form on the drip irrigation belt blank. The forming speed of the drip irrigation belt is closely related to the running speed of the traction drip irrigation belt, and the running speed of the traction drip irrigation belt is closely related to the cooling speed after the drip irrigation belt is formed. In order to speed up the cooling rate of the drip irrigation belt, the measure taken in the prior art is to make the drip irrigation belt pass throu...
