The present application relates to the technical field of plastic extrusion molding, and discloses a drip irrigation belt anti-blocking performance strengthening production system and method, which comprises the following steps: providing a steady-state molten polymer base flow, and superimposing a periodic pulse flow on the base flow; and after the action of each cycle of the pulse flow, analyzing the real-time rheological properties of the molten polymer according to the pressure decay curve monitored by a pressure sensor, and then adjusting the control parameters of the subsequent pulse flow. The present application establishes a dynamic micro-forging molding mode, thereby avoiding the molding defects of the micro-channel of the drip head inside the drip irrigation belt. The process action and process sensing are integrated in the present application, so that the production system can actively adapt to the fluctuations in the physical properties of the raw materials, and finally the product obtains the anti-blocking property due to its internal structural integrity.

This utility model discloses a welding wire feeding device for a welding robot, relating to the field of welding robot technology. It includes a U-shaped base, a column fixedly mounted on one side of the upper part of the U-shaped base, a sliding sleeve slidably mounted on the column, and a U-shaped frame fixedly mounted on one side of the sliding sleeve. The two ends of the U-shaped frame can be detachably connected to a welding wire hopper. A pair of straight wheels are fixedly mounted below the two ends of the U-shaped base. A caster is fixedly mounted below the column on the U-shaped base. A welding wire driving assembly is located at the upper end of the column. This device can drive the U-shaped frame to rise or fall via the sliding sleeve. The welding wire hopper can be lifted by connecting the hook on the U-shaped frame to the welding wire hopper, allowing it to leave the ground. The straight wheels and caster can push the device to move, thereby moving the welding wire hopper. The welding wire is clamped by pressure rollers and support rollers. Power is transmitted to the support rollers via a worm gear mechanism. The self-locking function between the worm gear and worm prevents the welding wire from being pulled back into the welding wire hopper.
