Improved film cutter

Abstract

The invention discloses an improved film cutter which comprises a rectangular box, a sawtooth cutter, a press plate, a fixed support and a movable support. The sawtooth cutter is arranged on one side of the rectangular box, the press plate is installed at the bottom of the rectangular box and is installed at the bottom of the box through a screw and a spring washer, and the fixed support is fixedly installed at one end of the box. The improved film cutter is characterized in that the movable support is arranged on the other side of the box and is inserted between the bottom of the box, mandrels are installed on the movable support and the fixed support, alarming devices are installed on the mandrels, an infrared detection device is installed at the bottom of the rectangular box, a detecting lamp connected with the infrared detection device is arranged outside the rectangular box, and the rectangular box is provided with a movable upper cover. The improved film cutter has the advantages that the rectangular box is provided with the movable upper cover, and dust can be blocked; the alarming devices can remind people of timely replacing a roll type film when no film is available; and an ultraviolet detecting device is arranged in the rectangular box and can be used for detecting whether the film is damaged.

Description

technical field [0001] The present invention relates to cutters, and more particularly to an improved film cutter. Background technique [0002] The existing film cutting machine is a closed box with a film channel on one side. The roll film is placed in the box, pulled out from the channel, and then cut off by a sawtooth cutter at the channel opening. However, for some telescopic For permanent film, it is easy to be pulled and damaged. If it is damaged inside the box, it is not easy to be found, which will cause inconvenience in the next use, and the closed box is inconvenient to replace the roll film, and the open box is easy. The roll film is contaminated with dust, which makes it difficult to use. [0003] Therefore, there is an urgent need for an improved technology to solve this problem in the prior art. Contents of the invention [0004] It is an object of the present invention to provide an improved film cutter. [0005] The technical scheme adopted in the prese...
