[0044] The working principle of this utility model:

[0045] How to use the rectangular steel pipe needle marking production line:

[0046] The utility model discloses a rectangular steel pipe needle-punching marking production line suitable for marking rectangular steel pipes. During marking, the utility model is docked with the rectangular steel pipe production line.

[0047] During the production process, when the rectangular steel pipe production line conveyor roller 1 conveys the rectangular steel pipe 4 to the corresponding position of the pipe turning device of the utility model, the controller automatically starts the pipe turning device, and the pipe turning device turns the rectangular steel pipe from the rectangular steel pipe production line conveyor roller to the chain conveyor device 1. The chain conveyor device 1 drives the rectangular steel pipe to run in the direction of the needle-punch marking device. Driven by the conveyor chain 1, the rectangular steel pipe crosses the pipe blocking device and the pipe pushing device until it reaches the end of the chain conveyor device 1; when four rectangular steel pipes arrive at the end of the chain conveyor device 1, the pipe pushing device is started, and the pipe pushing device pushes the four rectangular steel pipes to the marking position on the bundling device, and the pipe pushing device Return; start the alignment device, which aligns the ends of the four rectangular steel tubes on the same plane; operate the marking part of the needle-punch marking device to mark. The specific operation is to manually hold the handrail and control the marking part to approach the rectangular steel tube. Move the marking part so that the positioning plate of the locator hooks the end face of the rectangular tube, so that the marking machine needle is in the predetermined position, and each electromagnet group is pressed against the upper surface of the rectangular tube; then, turn on the electromagnet group switch, the electromagnet group is energized to generate magnetic force, so that the marking machine is tightly fixed on the rectangular tube, and then turn on the marking switch. The controller will automatically control the marking machine to engrave the characters on the rectangular tube and engrave the identification symbols pre-set in the controller. After marking is completed, turn off the marking switch, and then turn off the electromagnet group switch. The electromagnet group loses power and loses magnetism, and the marking part is controlled to rise. At this time, the bundling device automatically lowers the four rectangular steel tubes that have been marked down a certain distance (the distance is the height of the rectangular steel tube), completing the marking and bundling of one layer of rectangular steel tubes, waiting for the subsequent rectangular steel tubes to be marked.

[0048] When the chain conveyor device 1 drives the rectangular steel pipes to cross the pipe blocking device, and four consecutive rectangular steel pipes cross the pipe blocking device, the pipe blocking device is activated, and the baffle of the pipe blocking device rises to block the rectangular steel pipes that are subsequently flipped over by the pipe turning device; when the pipe pushing device pushes the first four rectangular steel pipes to the marking position on the stacking device, the baffle of the pipe blocking device falls, and the chain conveyor device 1 continues to convey the rectangular steel pipes. The pipe pushing device, the alignment device, and the needle-piercing marking device repeat the aforementioned pipe feeding, alignment, and marking actions in a cycle. When the marking and bundling are completed layer by layer and the predetermined number of layers is reached, the stacking device automatically descends and flattens the baffle, and places the completed bundled rectangular steel pipes on the chain conveyor device 2. The chain conveyor device 2 then transports the rectangular steel pipe bundles to the packaging device, which then packages them and controls the water with the water control device. After the previous group of steel pipe bundles is removed, the stacking device rises to continue bundling the subsequent rectangular steel pipes.

[0049] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
