Description

inkjet printer for cable

technical field

The utility model relates to an ink-jet printer for an outer sheath of a cable or an optical cable.

technical background

In the actual cable manufacturing process, inkjet printing is often required on the surface of the outer sheath to mark the necessary information such as cable model, specification, manufacturer, etc. Existing printers generally include a printer body with an ink cartridge inside and a print head fixedly connected to the body. During printing, a cable passes under the print head, and the print head receives print execution information at regular intervals to perform inkjet printing.

When printing, the cable will jump up and down due to factors such as uneven force or its outer sheath is not round, and sometimes it will hit the print head, thereby damaging the print head. Sometimes in order to get a better quality of printed fonts, the staff often need to constantly adjust the position of the print head, but this is not only difficult to ensure the effect of the actual printed fonts, but also the cable is easy to hit the print head, causing the print head to fail, making it unable to continue working.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide an inkjet printer for cables, which can well protect the print head and reduce the failure of the print head.

The technical solution adopted by the utility model is: an inkjet printer for cables, which includes a printer body with an ink cartridge inside and a print head fixedly connected to the body, the bottom cover of the print head is provided with a shell, so The bottom of the shell is provided with an ink jet hole, and the shell is elastically connected to the print head through an elastic element.

There is a guiding piece extending along the axial direction of the printing head inside the housing, and the printing head is slidingly fitted with the guiding piece.

The printer also includes a pressure sensor and an alarm display device electrically connected to the pressure sensor, the pressure sensor is fixedly arranged on the casing, and one end of the elastic element is fixedly connected to the On the above print head, the other end of the elastic element is fixedly connected to the pressure sensor.

Part of the outer surface of the shell is inwardly recessed.

The utility model has the advantages compared with the prior art:

1. The shell is elastically set on the print head, so that when the cable jumps up and down, it can only touch the shell and not hit the print head, so it not only ensures the printing effect, but also greatly reduces the failure of the print head;

2. There is no need to adjust the position of the print head many times, so the work efficiency is improved, and the operation is more convenient and reliable;

3. The shell adopts a concave shape that is easy to hold, which is convenient for personnel to work when adjusting the height of the print head.

Detailed ways

Referring to accompanying drawing 1, a kind of inkjet printer for cable, it comprises: the printer body 9 that has ink cartridge 8 inside and the print head 3 that is fixedly connected with described body 9, it is characterized in that: the bottom of described print head 3 The cover is provided with a shell 4, and the bottom of the shell 4 has an ink jet hole 10, and the shell 4 is elastically connected to the print head 3 through the elastic element 2.

The printer also includes a pressure sensor 6 and an alarm display device 1 electrically connected to the pressure sensor 6, the pressure sensor 6 is fixedly arranged on the shell 4, and the elastic element 2 One end is fixedly connected to the printing head 3 , and the other end of the elastic element 2 is fixedly connected to the pressure sensor 6 . The elastic element 2 can be a compression spring or a tension spring.

During printing, the cable 7 passes under the print head 3 , ink is ejected from the print head 3 , and adheres to the cable 7 through the ink ejection hole 10 . When the cable 7 to be printed shakes and hits the print head 3, the movable casing 4 is first moved upwards by the impact force, and the spring element 2 connected with it will make the print head 3 move upwards by a large upward pulling force. Such a movement process keeps the surface of the cable 7 to be printed on and the print head 3 within a relatively stable distance range. In addition, when the vibration range of the cable 7 is too large, the pressure sensor 6 connected to the elastic element 2 sends a signal to the alarm display device 1 for alarm, thereby reminding the operator to readjust the print head 3 to a proper position.

The inside of the housing 4 has a guide 5 extending axially along the print head 3, and the print head 3 is slidably fitted with the guide 5 to ensure that the housing 4 receives the cable 7. During the impact, it can go up and down vertically to avoid deflection.

Part of the outer surface of the housing 4 is inwardly recessed, which is convenient for personnel to hold during adjustment.

The "up" and "down" positional relationship described in this specification corresponds to the upper and lower positional relationship shown in Figure 1 .
