The first pipeline 32, the second pipeline 33 and the third pipeline 34 are arranged in parallel in the drag chain structure 70, and one end of the drag chain structure 70 is adjacent to the installation platform 50.

[0029] In this embodiment, the drag chain structure 70 facilitates the neat movement of the wire tubes during the forward and backward movement of the telescopic mechanism, and the setting of the drag chain structure 70 is beneficial to the arrangement and storage of the wire harness, and also facilitates maintenance of the equipment by technicians in this field.

[0030] In one specific embodiment, the ejector tube 31 is a straight tube structure, and guide rods 42 parallel to the ejector tube 31 are arranged on both sides of the ejector tube 31, and the guide rods 42 are suitable for being fixed to the feeding machine equipment, and guide pulleys 51 are arranged on both sides of the ejector tube 31 near its input end, and the guide pulleys 51 match the guide rods 42. The mounting platform 50 can drive the ejector tube 31, the first pipeline 32, the second pipeline 33 and the third pipeline 34 to move back and forth in the direction of the guide rod 42.

[0031] In one specific embodiment, the mounting platform 50 is a rectangular plate, and the length direction of the mounting platform 50 is arranged in the same direction as the ejector tube 31, and the mounting platform 50 is arranged horizontally.

Guide rods 42 are set on both sides of the main equipment to prevent the equipment from tilting and running off. The equipment adopts a manual control mode. After the drum is finished, the operator operates the equipment and clicks one button to clean it. The equipment can choose to use compressed air or steam as two media to inject tap water. The main purpose of the injection is to increase the pressure of the tap water. The cleaning time is centrally controlled by the PLC. When the one-button cleaning is clicked, the sealing door set at the feed end of the drum will automatically open, and the equipment will move forward at the set time. When it enters the inside of the drum, the cleaning work will start. The equipment can be set to a one-way cleaning mode: so it starts cleaning from the feed end, and after reaching the set position, the spray mode is turned on to blow away the remaining water stains in the cleaning pipeline. Then the equipment shrinks backward until it reaches the set position and stops. A reciprocating cleaning mode can also be set: so it automatically shrinks backward after the forward cleaning reaches the specified position. At this time, the control valve is not closed until the drum outlet position stops closing the water vapor and the compressed air is turned on to blow the remaining water stains in the pipeline. The equipment automatically withdraws from the drum and closes the sealing door to complete the entire cleaning process.
