Abstract

The utility model relates to a punching mechanism of a drop irrigation tape punching machine, comprising a servo motor, a driving synchronous pulley, a first eccentric wheel fixed on the driving synchronous pulley, a driven synchronous pulley, a second eccentric wheel fixed on the driven synchronous pulley, a synchronous belt and a punching tool bar. The driving synchronous pulley is installed on the output shaft of the servo motor; the punching tool bar is respectively connected with the two eccentric wheels through two bearings positioned on eccentric positions, i.e. a first bearing and a second bearing are respectively embedded on up-down corresponding eccentric positions of the two eccentric wheels; and the punching tool bar is fixed on a transmission shaft arranged in two bearing inner sleeves. The utility model has the advantages that because the punching tool bar not only makes up-down longitudinal motion, but also makes circumference motion so as to enable a punching cutter and a drop head on a punched drop irrigation tape to keep synchronous motion and enable the punching mechanism to easily punch on the tape wall of the drop irrigation tape splicing with the drop head.

Description

The perforating mechanism of drip irrigation zone puncher

Technical field

The utility model relates to the perforating mechanism of a kind of drip irrigation zone puncher.

Background technology

At present, the perforating mechanism of Chang Yong drip irrigation zone puncher is made up of motor and the runner that cutter is installed.Its course of work is as follows: when motor rotates, when being installed in water dropper on touching the drip irrigation zone of cutter on the runner, utilize extruding to mark micropore, cutter only moves in a circle, and does not have the punching press effect, and the punching effect is bad.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of perforating mechanism of the drip irrigation zone puncher that can accurately punch at a high speed.

The utility model adopts following technical scheme:

The utility model by servomotor, main frame synchronous pulley, be fixed on first eccentric wheel, driven synchronous pulley on the active synchronization belt wheel, be fixed on second eccentric wheel on the driven synchronous pulley, band, punching knife bar are formed synchronously; The active synchronization belt wheel is installed on the output shaft of servomotor, the punching knife bar is connected with two eccentric wheels respectively by two bearings that are positioned on the eccentric position, be that clutch shaft bearing and clutch shaft bearing are embedded in respectively on two eccentric corresponding up and down eccentric positions, the punching knife bar is fixed on and is contained on two power transmission shafts in the bearing inner sleeve.

The utility model beneficial effect is because the punching knife bar time has upper and lower lengthwise movement, again circular motion arranged in work, thereby the water dropper on the drip irrigation zone that makes perforating cutting tool and be perforated keeps being synchronized with the movement, and can portal in the drip irrigation zone band wall upper punch that is bonded with the water dropper place easily.

Description of drawings

Fig. 1 is the utility model structural representation.

In Fig. 1: 1 active synchronization belt wheel, 2 first eccentric wheels, 3 are with synchronously, 4 second eccentric wheels, 5 driven synchronous pulleys, 6 punching knife bars, 7 drip irrigation zones, 8 water droppers, 9 second bearings, 10 clutch shaft bearings.

The specific embodiment

By shown in Figure 1, embodiment as can be known, it by servomotor, main frame synchronous pulley 1, be fixed on first eccentric wheel 2, driven synchronous pulley 5 on the active synchronization belt wheel 1, be fixed on second eccentric wheel 4 on the driven synchronous pulley 5, be with 3 synchronously, punching knife bar 6 forms; Active synchronization belt wheel 1 is installed on the output shaft of servomotor, punching knife bar 6 is connected with two eccentric wheels respectively by two bearings that are positioned on the eccentric position, be that clutch shaft bearing 10 and clutch shaft bearing 9 are embedded in respectively on two eccentric corresponding up and down eccentric positions, punching knife bar 6 is fixed on and is contained on two power transmission shafts in the bearing inner sleeve.
