Description
Technical Field
[0001] The utility model relates to the technical field of pipeline cutting, and more specifically to a multi-station cutting pipe cutting machine. Background Art
[0002] Plastic tubing is a lightweight, flexible pipe that is widely used in many industries. With its unique physical and chemical properties, this pipe plays an important role in daily life and industrial applications.
[0003] Existing pipe cutting machines for cutting plastic pipes generally fix the position of the plastic pipe by clamping to keep the position of the plastic pipe stable during the cutting process. In order to improve the cutting efficiency, a multi-station one-time cutting structure is usually used. However, during the cutting process, multiple plastic pipes are generally placed side by side and close to each other. In this way, when cutting plastic pipes of different sizes, the thrust will cause the plastic pipe to deviate in the pushing direction, making it inconvenient for the subsequent plastic pipe to push out the cut plastic pipe, affecting the feeding. Therefore, a multi-station pipe cutting machine with adjustable limit size is needed. In view of this, we propose a multi-station pipe cutting machine. Utility Model Content

[0030] In an embodiment of the utility model, a plurality of limit blocks 402 are fixedly provided on the outer surface of the conveyor belt 401 of the material guiding component 4, and a limit gap is reserved between any two of the limit blocks 402, the connecting surfaces between the long sides on both sides of the limit blocks 402 are both inclined portions 403, and the inclination directions of the inclined portions 403 on both sides are opposite; the placement positions of a plurality of plastic pipes can be limited by the limit gap reserved between the limit blocks 402, and the setting of the inclined portions 403 on both sides of the limit blocks 402 facilitates the adjustment of the angle, so as to be suitable for limiting and guiding materials for pipes of different thicknesses.

After the placement is completed, the upper material guide component 4 is moved downward to fit the upper surface of the plastic pipe, and then the servo motor can be operated. The friction force can be used to withdraw the plastic pipe to the right, so that the side end of the plastic pipe enters the groove 502, and at the same time The equilateral trapezoidal strip 506 arranged in the through groove 502 can limit the plastic pipe. When the required length for cutting is reached, the material guide component 4 stops working, and the position of the plastic pipe is kept fixed. Then, several pipes can be cut under the operation of the cutting mechanism 6. In this way, the pipe can maintain a stable position during the cutting process. After the cutting is completed, the electric push rod 505 can be moved up, and then the cut pipe can be squeezed out under the continued operation of the material guide component 4, so that the cutting work can be repeated. Through such structural coordination, the plastic pipe feeding can be kept stable and not easily piled up, which effectively improves the effect of structural coordination.
