[0036] The material tray includes a feeding tray 4 and a loading tray 51 arranged coaxially. The feeding tray 4 is rotatably installed on the rotating bracket 3. The feeding tray 4 is a non-powered tray or a powered tray, that is, it can rotate by relying on the pulling force of the material pipe or can be driven by a motor; the loading tray 51 is rotatably installed at the upper end of the feeding tray 4 and is coaxial with the feeding tray 4. The loading tray 51 is also a non-powered tray, which is mainly used for the placement of the pipe material coil and the setting of the variable-diameter tensioning mechanism 6. Specifically, the variable-diameter tensioning mechanism 6 is installed on the feeding tray 4. At the same time, a strip-shaped groove 510 is opened on the loading tray 51. The strip-shaped groove 510 is used for the material rod 63 of the variable-diameter tensioning mechanism 6 to pass through and allow its radial movement, thereby realizing variable diameter and achieving the functions of tensioning or relaxing, and ensuring the stability of the pipe material during cutting.

[0037] In order to improve the overall structural compactness and aesthetics, a cylindrical material cylinder 52 is provided at the edge of the feeding tray 4. The material cylinder 52 is coaxial with the feeding tray 4. The loading tray 51 is located inside the material cylinder 52. A material placement area is formed between the upper surface of the loading tray 51 and the inner wall of the material cylinder 52 for placing the pipe material coil; a notch is opened on the side wall of the material cylinder to form a discharge port, which faces the guiding mechanism for discharging the pipe material.

[0038] Specifically, the variable-diameter tensioning mechanism 6 further includes a guide rail 61 fixed on the blanking disk 4. In this embodiment, the axis of the guide rail 61 is perpendicular to and intersects the axis of the blanking disk 4. There are at least three guide rails 61 and they are circumferentially evenly distributed. Preferably, there are three. A slider 62 is slidably arranged on the guide rail 61. The sliding direction of the slider 62 is perpendicular to and intersects the axis of the blanking disk 4. A material rod 63 is vertically fixed on the slider 62. The axis of the material rod is parallel to the axis of the blanking disk 4. A tensioning area is formed between the material rods 63 for contacting the central hole of the pipe material coil to achieve tensioning or relaxation. At the same time, a pushing device 64 is provided between the blanking disk 4 and the loading disk 51. The pushing device 64 can make the loading disk 51 and the blanking disk 4 rotate relative to each other. In this embodiment, the pushing device 64 is a cylinder or an electric push rod. Its length direction forms a certain angle with the radial direction of the blanking disk or the loading disk 51. One end of it is hinged to the blanking disk 4 and the other end is hinged to the loading disk 51. During adjustment, through the telescopic movement of the cylinder, the relative rotation of the loading disk 51 and the blanking disk 4 is realized. At the same time, the strip-shaped groove 510 is an inclined guide groove. Its length direction is inclined to the radial direction of the loading disk 51. In this application, the strip-shaped groove 510 is an arc-shaped groove. It can allow the material rod 63 to pass through and provide a movement space for the radial inward and outward movement of the material rod 63. At the same time, the strip-shaped groove forms a certain angle with the radial direction of the loading disk 51. When the loading disk 51 rotates relative to the blanking disk 4, the strip-shaped groove 510 has a guiding effect on the material rod 63. The side wall of the strip-shaped groove 510 contacts the side wall of the material rod 63. When the loading disk 51 rotates, the strip-shaped groove can drive each material rod 63 to move inward or outward synchronously to achieve variable diameter.

[0039] The braking mechanism 7 is installed on the rotating bracket 3 and is used to lock and fix the material disk. Specifically, the braking mechanism 7 includes a clamping cylinder 71. In this application, the clamping cylinder 71 has two output ends, and the two output ends can move closer to or away from each other. The direction of their approaching or separating is parallel to the rotation axis of the material disk. Braking blocks 72 are arranged on both output ends. Through the action of the clamping cylinder 71, the mutual approaching or separating of the two braking blocks 72 can be realized. A braking area is formed between the two braking blocks 72. The edge of the material disk is located in the braking area, or a braking piece is provided on the material disk and the braking piece is located in the braking area. The braking is achieved by the braking blocks 72 clamping the edge of the material disk or clamping the braking piece. In this embodiment, the edge of the blanking disk 4 is located in the braking area. During braking, the two braking blocks 72 clamp the edge part of the blanking disk 4 to achieve braking (braking) of the material disk.

[0040] To improve the supporting force of the loading tray 51 and prevent it from deforming, a first support base 41 is provided at the upper end of the unloading tray 4. There are multiple first support bases 41 which are circumferentially evenly distributed. They are arranged at the end far from the rotating shaft and are used to support the loading tray 51. At the top of the first support base 41, there are balls or bearings (rollers). The balls or bearings can contact the bottom surface of the loading tray 51. While achieving support, the friction between the loading tray 51 and the first support base 41 during rotation is reduced, the rotation smoothness of the loading tray 51 is improved, and the load on the pushing device 64 is reduced.

[0041] To improve the supporting force of the unloading tray 4 and prevent it from deforming, a second support base 8 is provided on the rotating bracket. There are also multiple second support bases 8 which are circumferentially evenly distributed. They are arranged at the end far from the rotating shaft. On the second support base 8, there are balls or bearings (rollers). The balls or bearings contact the lower bottom surface of the unloading tray 4 to support the unloading tray 4, improve its stability during rotation, and prevent it from deforming.

[0042] The material guiding mechanism 9 is arranged on the second support 12. A material guiding channel is provided on the material guiding mechanism 9. It can allow the pipe material to pass through and is used to guide the pipe material to smoothly enter the cutting area, ensuring the smoothness and accuracy of the pipe material during the cutting process. The axis of the material guiding channel is parallel to the rotation axis of the rotating bracket 3. In this embodiment, the axis of the material guiding channel and the axis of the rotating bracket 3 are in the same vertical plane.

[0043] Specifically, the material guiding mechanism 9 includes a lower guide roller 91 and an upper guide roller 92. There are two upper guide rollers 92 and two lower guide rollers 91, and they are arranged in parallel. In this embodiment, they are both horizontally arranged. Among them, the upper guide roller 92 is located directly above the lower guide roller 91 and can move up and down through a lifting cylinder 94. A material passing area is formed between the lower guide roller 91 and the upper guide roller 92 for the pipe material to be cut to pass through. At the same time, vertical guide rollers 93 are provided on both sides of the inlet end and the outlet end of the material passing area. The axis of the vertical guide roller 93 is perpendicular to the axis of the upper guide roller 92 or the lower guide roller 91. In this embodiment, they are all perpendicular to the horizontal plane. The above-mentioned lower guide roller 91, upper guide roller 92 and vertical guide roller 93 form a material guiding channel for guiding the pipe material to discharge. During guiding, the vertical guide rollers on both sides of the inlet end and the outlet end of the material passing area are used to limit the left and right positions and guide the material pipe during the conveying process. The upper guide roller 92 can move up and down, thereby controlling the height of the material passing area, adjusting the clamping force on the material pipe, and then achieving different frictional forces on the material pipe during the conveying process to realize the smooth conveying of the pipe material.
