Description

Technical Field

[0001] The utility model belongs to the technical field of pipe cutting equipment, in particular to an automatic pipe cutting machine for acrylic PVC pipes. Background Art

[0002] Acrylic and PVC are two common plastic materials at present. Pipe cutting machines are needed in daily processing of acrylic and PVC pipes.

[0003] For example, patent CN218255431U discloses a PVC pipe cutting device, which includes a cutting table and a cutting machine body located above the cutting table and supported by a support plate; it also includes a clamping assembly symmetrically installed on the surface of the cutting table, the clamping assembly includes a clamping frame, a fixed arc plate, a movable arc plate, a screw and an adjusting part, and the fixed arc plate is fixedly installed inside the clamping frame.

[0004] When the above-mentioned cutting device is in use, the diameter of the pipe is generally required to be smaller than the diameter of the cutting blade to ensure that the pipe is cut in one go. When the pipe diameter is larger (at least larger than the diameter of the cutting blade), the cutting blade cannot form a one-time cutting shape. At this time, during the cutting process, personnel are required to intermittently switch and adjust the angle of the clamped pipe. This process is too complicated, and manual intervention may cause deviation in the cutting angle. For this reason, we propose an automatic acrylic PVC pipe cutting machine to solve the above problems. Utility Model Content

At this moment, the driven gear frame 61 engaged on one side of the driving gear 623 will rotate circumferentially in cooperation with the movable guide groove 622 through the rotating side sleeves 621 on both sides of itself. Since the inner side wall of the driven gear frame 61 is provided with an adjusting component 63 as a whole, the cutting assembly 636 in the adjusting component 63 will also perform corresponding circumferential cutting operations around the pipe to be cut along the above-mentioned transmission.
