Problems solved by technology
However, the extrusion rate of the current sprinkler belt production line can reach 50-100 m / min. Due to the mismatch of the speed of the pneumatic punching, it not only leads to low production capacity of the sprinkler belt, but also unstable operation during the production process.
The main manifestations are: first, the electromagnetic valve controlling the cylinder is easy to age, causing the speed of punching to be fast and slow, or even stop, and it is out of sync with the running hose, and the hose often breaks the punching needle; The stroke control accuracy of the cylinder is low, and the depth of the punching needle is different when punching, and it is easy to break the needle if it is deep; the third is that the air pressure of the compressed air cannot be controlled absolutely uniformly, resulting in the frequency of punching. Frequent downtime, high scrap rate, generally only about 90% genuine product rate
[0003] In order to solve the above problems, some people have developed online laser drilling. Although the problem of breaking the punching needle has been solved, the current speed of online laser drilling is only about 20 meters per minute, with low output and high cost.
There is also a cam structure used to drive the slide bar on the needle plate to move up and down to punch holes. Although the theoretical punching speed can reach 100 meters per minute, because the motion pressure of the cam is not a linear motion, there is a pressure of about 30° Angle, the pressure of the pressure angle causes the needle plate slider to swing when it moves up and down. The higher the punching speed, the greater the jump of the needle plate. In actual work, it can only be controlled at about 40 times per minute to maintain production, and the needle is often broken. The scrap rate is high, and the depth of punching is difficult to control

The invention relates to a rocker arm type perforating machine for a water-saving irrigation water sprinkler tube and belongs to the technical field of agricultural water-saving irrigation production. The rocker arm type perforating machine is composed of a rack, a dragging bracket, a conveying bracket, a perforating platform, a rocker arm ejection rod, a rocker arm bracket, a rocker arm, a slide rod, a slide plate, a needle plate, a servo motor and the like, wherein the conveying bracket and the dragging bracket are mounted on the rack respectively; a conveying roller is arranged on the conveying bracket and a dragging roller is arranged on the dragging bracket; the perforating platform is arranged in the middle part of the upper face of the rack and is provided with the rocker arm ejection rod, the rocker arm bracket, the rocker arm, the slide rod, the slide plate and the needle plate; a rocker arm ejection rod seat and the rocker arm ejection rod are connected by a concave-convex spherical surface. The rocker arm ejection rod seat and the ejection rod are combined by the concave-convex surface so that the ejection force is transmitted, and the ejection rod is provided with a straightening guide pipe capable of resolving mechanical vibration caused by cam transmission; the problems in the prior art that the swinging is great, the speed is slow, a needle is usually broken, the rejection rate is high and the perforating depth is difficult to control when a cam structure is used for driving the slide rod on the needle plate to move up and down to perforate are solved completely.
Description
Technical field [0001] The invention relates to a rocker type punching machine for a water-saving irrigation water spray belt, belonging to the technical field of agricultural water-saving irrigation production. Background technique [0002] At present, the punching machine for producing irrigation sprinkler belts generally adopts pneumatic punching method. Because pneumatic punching uses compressed air to drive the cylinder to reciprocate, the punching volume per minute does not exceed 80 times. The production is N45 The water spray belt with five oblique holes and 200 mm spacing has a linear speed of only about 21 meters per minute. However, the current water spray belt production line can match the main machine with an extrusion capacity of 50-100 m / min. Due to the mismatch of the pneumatic drilling speed, it not only causes the production of the water spray belt to be low, but also unstable operation during the production process. The main manifestations are: First, the sole...
