Description

Technical Field

[0001] The utility model relates to the technical field of cable marking machines, in particular to a laser printing auxiliary structure and a cable laser marking machine. Background Art

[0002] Laser marking is a non-contact processing method that does not cause mechanical extrusion or mechanical stress to the material, does not pollute the workpiece, and produces delicate and high-precision products. It is widely used in cable marking. For example, patent CN 204712659U discloses a cable and tube laser marking machine, which connects the encoder (sensing guide wheel) with the lifting and clamping device (meter guide wheel). When the lifting and clamping device rotates to transmit the wire, it can synchronously drive the encoder to rotate. When the encoder rotates, it detects the flow distance of the cable or tube in real time and transmits it to the laser flight marking card to achieve real-time marking.

[0003] Since the sensor guide wheel is the sensing device of the laser printer and is connected to the laser printer host, after setting the words to be laser printed on the laser printer and clicking the laser machine operation screen to start printing, the laser machine equipment will start printing only when the sensor guide wheel rotates. If the sensor guide wheel does not rotate, the laser machine will not work even if you click the start printing button on the laser machine operation screen.

[0004] However, due to the friction between the sensor guide wheel and the meter guide wheel, the outer wall of the sensor guide wheel is easily worn and damaged after long-term use, resulting in the meter guide wheel being unable to continuously drive the sensor guide wheel to rotate and often stopping, causing the printer to sometimes work and sometimes not work, and the printed content to be discontinuous and complete.

[0035] In the laser printing auxiliary structure 100 provided by the present invention, when the outer wall surface of the sensor guide wheel 4 is worn and missing, the limiting structure 5 can be removed from between the platform 1 and the seat body 3, and then the seat body 3 is moved in the direction close to the meter position 11 until the outer wall surface of the sensor guide wheel 4 can be pressed against the outer wall surface of the meter guide wheel 2 again; then the limiting structure 5 is re-placed between the platform 1 and the seat body 3 to limit the movement of the seat body 3 relative to the platform 1, to ensure that the sensor guide wheel 4 is stably pressed against the meter guide wheel 2, so that the meter guide wheel 2 can continuously drive the sensor guide wheel 4 to rotate, thereby improving the laser marking accuracy; and the structure is simple, the operation is easy, and the cost is low.
