Cutting mechanism capable of being finely adjusted in vertical direction

Abstract

The invention discloses a cutting mechanism capable of being finely adjusted in a vertical direction. The cutting mechanism comprises a bracket as well as an upper driving device and a lower driving device which are arranged on the bracket; an upper cutting plate is arranged at the bottom end of the upper driving device; the upper driving device drives the upper cutting plate to move up and down;a lower cutting plate is arranged at the top end of the lower driving device; the lower driving device drives the lower cutting plate to move up and down; fine adjustment devices are arranged betweenthe driving devices and the corresponding cutting plates; each fine adjustment device comprises a fine adjustment power source and a plurality of screw rods; the two ends of each screw rod are in shaft connection with the corresponding driving device and in threaded connection with the corresponding cutting plate respectively, or the two ends of each screw rod are in shaft connection with the corresponding cutting plate and in threaded connection with the corresponding driving device respectively; and the fine adjustment power source drives all the screw rods to rotate synchronously through atransmission belt. According to the cutting mechanism of the invention, all the screw rods are driven by the fine adjustment power source to rotate synchronously, and so that the vertical fine adjustment of the corresponding cutting plate is achieved through the rotation of the screw rods.

Description

technical field [0001] The invention relates to a cutting mechanism that can be finely adjusted up and down, and belongs to the field of sheet material cutting devices. Background technique [0002] After the sheet is molded, it is necessary to cut the formed unit from the sheet through a cutting device. The cutting is mainly realized by the relative movement of the upper and lower cutting boards. After a long time of use, the upper and lower cutting boards cannot be completely closed. , There will be tiny gaps, which will affect the cutting effect. There is no fine-tuning device in the existing cutting device, and the fine-tuning of the upper and lower cutting boards cannot be realized. Contents of the invention [0003] The invention provides a cutting mechanism that can be finely adjusted up and down, which solves the problems disclosed in the background technology. [0004] In order to solve the problems of the technologies described above, the technical solution adop...
