Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

As shown in Figures 1 and 2, a cutting machine for cutting plastic film includes a cam mechanism, a transmission mechanism and a cutting mechanism, the cam mechanism includes a grooved cam 1 and a camshaft 2, and the grooved cam 1 is installed On the camshaft 2, a rocker arm 3 is installed in the groove of the grooved cam 1, and the transmission mechanism includes a rocker arm 3, a rotating shaft 4, a transmission rod 5 and a pull rod 6, and the middle part of the rocker arm 3 is installed on the rotating shaft Above, the other end of the rocker arm 3 is connected to the transmission rod 5, the transmission rod 5 is connected to the pull rod 6, and the pull rod 6 is connected to the cutting mechanism, and the cutting mechanism includes a sliding column 7, a linear bearing 8, a front cutter body 9 and a rear The cutter body 10, the linear bearing 8 is fixed with the frame, the linear bearing 8 is equipped with a sliding column 7, one end of the sliding column 7 is connected with the pull rod 6, and the other end is equipped with a pair of front cutter body 9 and rear cutter body 10. The rear cutter body 10 is fixedly connected to the machine frame, and the front cutter body 9 is fixedly connected to the sliding column 7 .

The sliding column 7 is provided with at least 2 pairs of front cutter body 9 and rear cutter body 10 .

When actually cutting the plastic film, the cam shaft 2 rotates, the grooved cam 1 drives the rocker arm 3 to rotate, the rocker arm 3 drives the pull rod 6, the pull rod 6 drives the sliding column 7 to move on the linear bearing seat 8, and drives the front cutter body 10 to reciprocate and slide , Cut the plastic film when the front cutter body is in contact with the rear cutter body. According to the needs, the camshaft speed or the speed of the plastic film passing through the gap of the cutter body can be adjusted to obtain plastic films of different sizes.

It is not difficult to find that the utility model cleverly utilizes the characteristics of the cam mechanism to design a high-efficiency and high-standard cutting plastic film equipment. By adjusting the cam speed and the speed of plastic passing through the gap between the cutter body, it can achieve fast, high-efficiency and high-standard cutting plastic film. The utility model has the advantages of simple operation, obvious effect, manpower saving, simple and compact structure, easy portability and low cost.
