Description

Technical Field

[0001] The utility model belongs to the technical field of cable inkjet coding equipment, and particularly relates to a rotary encoder bracket device for a cable laser inkjet printer. Background Technique

[0002] In the field of cable inkjet coding equipment, the working principle of a laser inkjet printer is to use a laser to burn the required marks on the surfaces of various wires and cables. Compared with traditional inkjet printers, laser inkjet printers not only save consumables, but also the burned characters are beautiful, clear and do not fade, and will not fall off even in harsh outdoor environments with wind and sun exposure. Therefore, laser inkjet printers are becoming more and more popular in the current production of wires and cables.

[0003] A rotary encoder, also known as an encoder or a synchronous pulley for short, is used in a cable laser inkjet printer to convert the measured rotation angle of a length measuring wheel into a pulse or digital electrical signal through photoelectric conversion, so as to burn the required marks on the cable surface. At present, most rotary encoders used in cable laser inkjet printers do not have a reasonable bracket device. Since mechanical vibration will occur when the rotary encoder measures the rotation angle of the length measuring wheel, the mechanical vibration will inevitably distort or even disappear the output signal of the rotary encoder, resulting in measurement errors. Eventually, the marks burned on the cable surface by the cable laser inkjet printer are not those required for actual production, or the cable laser inkjet printer cannot work properly, which undoubtedly increases the production cost of the cable.

[0004] Based on the problems in the above background technique, the R & D personnel have proposed a rotary encoder bracket device for a cable laser inkjet printer. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rotary encoder bracket device for a cable laser inkjet printer, so as to solve the problem that the output signal of the encoder is distorted due to the mechanical vibration of the equipment during the cable inkjet coding process, and finally the cable marks sprayed do not meet the actual production requirements.

[0006] To solve the above problems, the technical solution of the utility model is as follows:

[0012] Furthermore, the wire of the rotary encoder is connected to the cable laser marking machine to ensure that a reliable pulse feedback signal is provided for the cable laser marking machine.

[0013] Furthermore, the lower bottom surface of the bracket of the bracket device is connected to the bottom plate by electric welding.

[0014] Furthermore, the driving gear is fastened on the side of the length measuring wheel by a second hexagon socket head cap screw; the length measuring wheel is connected to the length measuring wheel shaft through a bearing; the length measuring wheel shaft has a clearance fit with the machined holes on two support seats of the same size, and is axially limited by the first hexagon socket head cap screw threadedly connected to the support seat; the support seat is fastened on the bottom plate, and by adjusting the positions of the guide rollers on the bottom plate, the cable can always be kept at the center position of the length measuring wheel.

[0015] Furthermore, the installation groove machined on the bottom plate shall not affect the installation and adjustment of the length measuring wheel.

[0016] Furthermore, the module of the driven gear and the meshing driving gear should be the same, and the tooth number ratio of the two is in a multiple relationship.

[0017] The beneficial effects of the present utility model are as follows:

[0018] (1) The present utility model adopts a stable bracket structure and a variety of firm connection methods, so that the rotary encoder will not generate mechanical vibration when measuring the rotation angle of the length measuring wheel, ensuring that the rotary encoder can output a normal feedback signal, and at the same time will not affect the normal operation of the rotary encoder, enabling the cable laser marking equipment to spray the required marks on the cable, avoiding secondary marking or mark modification, and effectively reducing the actual production cost of the cable.
