DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0021] Please refer to Figs. 1 to 4 An embodiment provided by the utility model: a convenient-to-clean overlock machine cutter head structure, including stepper motor 1, the output end of stepper motor 1 is connected with eccentric wheel 2 through shaft coupling, the front side surface of eccentric wheel 2 is fixedly installed with connecting rod 4, the end of connecting rod 4 is movably installed with moving cutter 5 on the surface of rear side, the rear side surface of moving cutter 5 is movably installed with fixed plate 8, the front side of fixed plate 8 is movably installed with mounting plate 6, the top end surface of mounting plate 6 is fixedly installed with two baffles 12 near the position of moving cutter 5, and moving cutter 5 is movably clamped into the inside of baffle 12.

[0022] The position of connecting rod 4 near moving cutter 5 is fixedly installed with first fixed block 10, the inside of first fixed block 10 is provided with telescopic slot 16, the front side surface of moving cutter 5 is fixedly installed with telescopic rod 18, telescopic rod 18 is slidably inserted into the inside of telescopic slot 16, and extrusion spring 17 is movably installed between the outer surface of telescopic rod 18 and the inside of telescopic slot 16.

[0023] Through the cooperation of first fixed block 10 and baffle 12, when the overlock machine needs to be cut, moving cutter 5 can be rotated to the position between the two baffles 12 first, at this time, baffle 12 will be popped out by the elastic potential of extrusion spring 17 and clamped into the inside of baffle 12, at this time, moving cutter 5 will be attached to the surface of static cutter 7, so that shearing force is formed between moving cutter 5 and static cutter 7 when moving cutter 5 moves, so that cutting operation is carried out, when the lines remaining on the surface of moving cutter 5 need to be cleaned, moving cutter 5 can be pushed out to the rear side, at this time, moving cutter 5 is moved out from between the two baffles 12, then moving cutter 5 is rotated, so that the surface of moving cutter 5 is attached to the surface of baffle 12, so that moving cutter 5 and static cutter 7 are separated, so that moving cutter 5 is conveniently cleaned, and at the same time, the situation that shearing force between moving cutter 5 and static cutter 7 harms personnel when moving cutter 5 is moved during cleaning moving cutter 5 can be avoided.

[0024] The rear surface of the mounting plate 6 is movably mounted with a static cutter 7 near the position between the two baffles 12, and the surfaces of the moving cutter 5 and the static cutter 7 are in close contact with each other.

[0025] The front side of the mounting plate 6 is fixedly mounted with a second fixed block 11, and the front side of the fixed plate 8 is fixedly mounted with a movable rod 15.

[0026] Through the cooperation of the compression spring 14 and the movable rod 15, when the device pushes out the moving cutter 5 backward, the fixed plate 8 can move backward with the moving cutter 5, avoiding the situation that the moving cutter 5 is stuck, and the elastic force of the compression spring 14 on the movable rod 15 can make the stress on both ends of the moving cutter 5 uniform, avoiding the situation that the moving cutter 5 is skewed on the surface of the connecting rod 4.

[0027] The surface of the moving cutter 5 is provided with a mounting hole 9, and the mounting hole 9 is rotationally connected between the fixed plate 8.

[0028] The outer end of the eccentric wheel 2 is movably mounted with an adjusting eccentric block 3, the inside of the adjusting eccentric block 3 is provided with an adjusting groove, one end of the connecting rod 4 is movably mounted with a rotating shaft, and the rotating shaft is slidably clamped into the inside of the adjusting groove. When the overlock machine needs to cut, the moving cutter 5 can be rotated to the position between the two baffles 12 first, at this time, the baffles 12 will be extruded and popped out by the elastic potential energy of the extrusion spring 17 and clamped into the inside of the baffles 12, at this time, the moving cutter 5 will be in close contact with the surface of the static cutter 7, so that the shearing force is formed between the moving cutter 5 and the static cutter 7 when the moving cutter 5 moves, thereby cutting operation is performed;

[0029] When the line on the surface of the moving cutter 5 needs to be cleaned, the moving cutter 5 can be pushed out to the rear side, at this time, the moving cutter 5 is moved out from between the two baffles 12, and then the moving cutter 5 is rotated, so that the surface of the moving cutter 5 is in close contact with the surface of the baffle 12, thereby the moving cutter 5 and the static cutter 7 are separated, and the moving cutter 5 is conveniently cleaned, and at the same time, the situation that the shearing force between the moving cutter 5 and the static cutter 7 harms the personnel when the moving cutter 5 is cleaned can be avoided;

[0030] When the device pushes out the moving cutter 5 backward, the fixed plate 8 can move backward with the moving cutter 5, avoiding the situation that the moving cutter 5 is stuck, and the elastic force of the compression spring 14 on the movable rod 15 can make the stress on both ends of the moving cutter 5 uniform, avoiding the situation that the moving cutter 5 is skewed on the surface of the connecting rod 4.

[0031] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
