Description

Wire winding drum cutter Technical Field The invention relates to the technical field of plastic braiding processing, in particular to a wire winding drum cutter. Background Currently, manual wire cutters perform a cutting process by guiding a cutter to move in a straight line by a slide shaft. However, the wire cutter has the defects that on one hand, the starting of a cutter and the clamping of a wire winding barrel are mutually independent, cutting can be started even if the wire winding barrel is not clamped in place, and a large potential safety hazard exists, on the other hand, one end of the wire winding barrel needs to be manually fixed in the cutting process, the hand is easy to approach to a cutter area to increase scratch risk, the manual fixation is difficult to ensure stability, and the cutter is easy to shake or deviate during cutting, so that the accuracy and the integrity of primary cutting are affected. Disclosure of Invention Aiming at the defects existing in the prior art, the invention aims to provide a wire winding drum cutter so as to solve the technical problems of dispersed operation steps and unstable wire winding drum fixation and insufficient safety. In order to achieve the above purpose, the present invention adopts the following technical scheme: In one aspect, a wire reel cutter is provided, comprising: A first mounting area; A pushrod having a first support surface and configured to be controlled to move relative to the first mounting area; the second installation area is provided with a second supporting surface which is arranged opposite to the first supporting surface and is used for supporting the opposite end surfaces of the wire winding drum; the switching structure comprises a locking component and a cutting component, wherein the locking component is movably arranged in the second installation area and used for limiting or allowing the cutting component to move relative to the second installation area, and the locking component is configured to be triggered by the movement of the push rod into the second installation area and releases the limitation of the cutting component. In one embodiment, the locking assembly includes: the first sliding block is arranged in the second installation area in a sliding mode, and the sliding direction of the first sliding block is the same as that of the push rod and is driven by the push rod; The return piece is arranged between the second installation area and the first sliding block, and when the first sliding block slides, the return piece deforms to accumulate a resilience force for driving the first sliding block to return and move; the second sliding block is arranged in the second installation area in a sliding way, is connected with the first sliding block through a connecting rod, and is used for linking the second sliding block to slide when the first sliding block slides and limiting or allowing the cutting assembly to move.
