Description

Technical Field

[0001] The invention relates to the technical field of pipeline cutting, in particular to an annular automatic cutting device for pipelines. Background Art

[0002] Plastic pipes are referred to as PVC pipes. The main component of PVC pipes is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a synthetic material that is well-loved, popular, and widely used in the world today. As one of the products of scientific and technological development, PVC pipes are visible in daily life. When processing PVC pipes, they generally need to be cut. Due to the characteristics of PVC pipes, they have a certain degree of softness, and general cutting equipment uses single-piece cutting blades. When a single-piece cutting blade cuts it, it is easy for the pipe to deform, which in turn affects the cutting accuracy. In addition, PVC pipes are prone to burrs during the cutting process. After the pipe is cut, it must be manually removed, which affects the processing efficiency of the equipment, and further reduces the use effect of the equipment.

Even if the shape of the pipe changes during the cutting process, the cutting quality of the pipe can still be maintained due to the ring-shaped shape of the multiple cutting blades, and the material is prevented from changing, which affects the cutting accuracy, further improving the cutting accuracy of the equipment. When the cutting mechanism rotates, the grinding blade fits at the cutting port, and cooperates with the elastic force of the first spring to make it fit at the cutting port, and fully grinds the cutting port after cutting, and then further avoids burrs on the material after cutting, thereby requiring manual secondary cleaning, and the dust after grinding by the grinding blade can be sucked out by the pump, thereby effectively avoiding dust generated during cutting and grinding, further improving the practicality and ease of use of the equipment.

[0035] Working principle:

[0036] During operation, the material to be cut is first passed through the cutting mechanism 3, and the material is placed in the supporting mechanism 23. When the material passes through the cutting mechanism 3, the material is located between the multiple cutting blades 8, and at this time, the grinding mechanism 13 is attached to the pipe. Then, the telescopic rod 34 and the bidirectional screw 25 in the driving mechanism 30 are controlled to be engaged, and then the second driving motor 33 is controlled to work. At this time, the second driving motor 33 drives the bidirectional screw 25 to rotate, and then the two moving frames 26 approach each other. When the two moving frames 26 approach each other, the clamping mechanism on the moving frame 26 clamps the material, and the clamping mechanism The cooperation between the clamping piece 29 and the second spring 27 can effectively maintain the stability of the pipe during cutting. At the same time, the cooperation between the second spring 27 and the clamping piece 29 can be changed according to the size of the pipe, so that it can adapt to the fixing of pipes of different diameters, further improving the stability of the equipment during use. When the material is fixed, the telescopic rod 34 and the rotating column 32 are controlled to be engaged. At this time, the second drive motor 33 controls the speed regulating box 31 to work through the rotating column 32, and the speed regulating box 31 can effectively control the transmission rod 21 to work. When the transmission rod 21 rotates, the transmission rod 21 can control the second gear 22 to rotate. When the second gear 22 rotates, the second gear 22 drives the cutting mechanism 3 to work through the second gear ring 12, and then the cutting mechanism 3 performs annular cutting, and when the cutting mechanism 3 rotates, the first drive motor 10 controls the first gear 11 to rotate, and the first gear 11 controls the first gear ring 7 to rotate, and when the first gear ring 7 rotates, the pull rod 9 controls the multiple cutting blades 8 to approach, and then the cutting blades 8 fit the pipe and rotate with it, so that the pipe can be effectively cut, and even if the shape of the pipe changes during the cutting process, the pipe can still be kept because the multiple cutting blades 8 are annular. The cutting quality is improved to prevent the material from changing and affecting the cutting accuracy, thereby further improving the cutting accuracy of the equipment. When the cutting mechanism 3 rotates, the grinding sheet 18 is attached to the cutting port, and the elastic force of the first spring 15 is used to make it fit to the cutting port, and the cutting port after cutting is fully polished, thereby further avoiding burrs on the material after cutting, which requires manual secondary cleaning, and the dust after grinding by the grinding sheet 18 can be sucked out by the pump 19, thereby effectively avoiding the generation of dust when the material is cut and polished, further improving the practicability and ease of use of the equipment.
