[0015] Compared with the prior art, the present invention provides a copper tube cutting device with adjustable tube length, which has the following beneficial effects:

[0016] 1. The copper tube cutting equipment with adjustable tube length, the tube enters the equipment through the feed port and is fixed on the top of the support table by the fixing component to prevent the tube from moving during the cutting process. The fixing component ensures the stability during the cutting process and avoids the sliding and error of the tube. At the same time, the output end of the driving cylinder pushes the support seat to adjust the position to ensure that the position of the tube and the cutter are accurately aligned. Subsequently, the lifting cylinder drives the lifting plate to move up and down, thereby driving the cutter to cut the tube, which can realize automatic and precise cutting of copper tubes of different lengths, effectively improving the processing efficiency and product quality. After the cutting is completed, the adsorption component will lift the cut tube and transfer it to the collection area to realize automatic operation; the adsorption component quickly lifts and transfers the tube after cutting, which simplifies the operation process, reduces human intervention, and improves the overall work efficiency.

[0017] 2. The copper tube cutting equipment with adjustable tube length delivers the tube to the first contact plate through the feed port, and the deflection plate can be driven to deflect around the axis of the support seat under the action of the gravity of the tube. At the same time, the lifting plate is driven by the lifting cylinder to contact the tube to be cut, and the tube can be pressurized to avoid displacement of the tube during the cutting process, thereby improving the cutting accuracy. At the same time, the second contact plate can be in close contact with the tube under the elastic force of the reset spring to achieve the effect of stably pressing the tube. The lifting cylinder pushes the lifting plate to drive the cutter to move downward to cut the tube. After the cutting is completed, the tube slides to the discharge port through the supporting plate to realize automatic discharge. The inclined setting of the supporting plate and the discharge port facilitates the automatic sliding out of the cut tube, further improving the automation level and production efficiency of the equipment.

[0018] 3. The copper tube cutting equipment with adjustable tube length, when the lifting plate descends, the fixed suction cup contacts the surface of the tube and is fixed by vacuum adsorption, and the sliding rod in the hollow tube slides up and down under the action of external force. At the same time, the rotating rod in the mounting groove on one side of the hollow tube is rotatably connected with the sliding rod through the trigger rod. When the rotating rod rotates, the trigger rod pushes the sliding rod to move and adjusts the adsorption or release state of the suction cup, thereby realizing the grabbing and placing operation of the tube, and can realize stable and efficient tube adsorption and release functions. The fixed suction cup made of rubber ensures good sealing and adsorption effect on the surface of the tube, reduces the risk of tube sliding, improves the reliability of operation, and adapts to different tube specifications and positions, further improves the automation degree and operation efficiency of the equipment, helps to reduce manual intervention and improve production efficiency.

[0019] 4. The copper tube cutting equipment with adjustable tube length, when the driving plate rotates, drives the synchronous plate to move in the moving groove through the synchronous rod, so that one end of the synchronous plate is in contact with the tube at the feed port, and finally the accurate feeding and positioning of the tube is realized, while ensuring the continuity of the tube cutting. At the same time, a separation plate with a wavy structure is provided on one side of the lifting plate. When the separation plate contacts the tube on the feed port, the tube can be separated and neatly arranged, ensuring the smoothness and accurate positioning of the tube during the feeding process, ensuring that multiple tubes do not overlap or get stuck during the feeding process, and further improving the stability and work efficiency of the equipment.

[0020] 5. The copper tube cutting equipment with adjustable tube length, when the lifting plate moves up and down, the driving rod slides along the guide plate inclined on the support plate, and the driving rod contacts the first contact groove on the guide plate, thereby guiding the movement direction of the movable plate, and the movable plate rotates around the axis of the rotating shaft, so that the movable plate can assist in guiding the tube to be cut on the feed port, and guide the tube to the cutting position. At the same time, when the driving rod moves along the first contact groove, the guide slope contacts the trigger rod and controls its rotation, thereby realizing precise operation of the adsorption component, making the action of the adsorption component more flexible, and being able to quickly adapt to the position and angle changes of different tubes, further optimizing the operating efficiency and automation of the equipment, and being able to effectively reduce the occurrence rate of misoperation and failures, and improving the working efficiency and reliability of the equipment.
