The two sliders 13 are respectively fixed to the bottom of the two spindle boxes 14. The motor 11 drives and drives the bidirectional lead screw 12 to rotate. The bidirectional lead screw 12 drives the two sliders 13 to move, thereby moving the two spindle boxes 14 so that the edge rolling mold can clamp the paper tube to facilitate the rotation of the paper tube. The inner sides of the two spindle boxes 14 are provided with forming molds 15 connected to the main shaft, and the tops of the two spindle boxes 14 are installed with edge rolling assemblies 16. By setting the edge rolling assembly 16, the edge rolling work at both ends of the paper tube can be completed at the same time.

[0029] Specifically, an arc groove is provided on the surface of the movable seat 7 to facilitate the paper roll to be stably placed on the movable seat 7 .

[0030] Furthermore, the edge grinding assembly 16 includes a mounting plate 161 installed on the top of the two spindle boxes 14, a cylinder 162 is fixed in the mounting plate 161, a movable plate 163 is fixed on the telescopic shaft of the cylinder 162, and a fixed block 164 is fixed at the bottom of the movable plate 163 near both ends, and a pressure wheel 165 is fixed at the bottom of the fixed block 164.

[0031] According to the embodiment, when the paper tube is on the movable seat 7, the hydraulic cylinder 3 is started to work and drive the lifting plate 4 to move upward, the lifting plate 4 drives the base 6 to move upward through the guide column 5, and the base 6 drives the movable seat 7 to move upward. When the paper tube is moved by the movable seat 7 to the position between the two forming dies 15, the motor 11 is started and drives the bidirectional lead screw 12 to rotate, and the bidirectional lead screw 12 drives the two sliders 13 to move, thereby moving the two spindle boxes 14 so that the edge rolling dies can clamp the paper tube.

Then, the cylinder 162 is started to drive the movable plate 163 to move downward, and the movable plate 163 drives the pressure wheel 165 to move downward. The pressure wheel 165 contacts the steel rings at both ends of the paper tube and continues to move, thereby rolling the steel rings to form an R-shaped groove, so as to complete the edge rolling work at both ends of the paper tube at the same time.

[0032] Embodiment 2:

[0033] Combination Figure 1 , Figure 2 and Figure 4 As shown, on the basis of embodiment 1, the unloading assembly 9 includes a bracket 91 fixedly connected to the surface of the workbench 2, the bracket 91 is "U"-shaped, and two fixed cylinders 92 are fixedly provided on the top of the bracket 91. A spring 93 is installed in the fixed cylinder 92, and one end of the spring 93 is fixedly connected to a movable block 94.

[0035] Furthermore, a slanted unloading guide plate 17 is fixedly provided on one side of the workbench 2 away from the loading conveyor belt 10, so as to facilitate unloading of the processed paper tubes.

[0036] According to the embodiment, when the paper tube is pushed upward by the base 6, the push rod 8 squeezes the inclined surface of the movable block 94 and forces it to move toward the inside of the fixed tube 92. When the push rod 8 exceeds the position of the movable block 94, the movable block 94 is reset under the elastic force of the spring 93. When the paper tube is edge-milled, the paper tube moves downward with the base 6. At this time, the push rod 8 does not push the movable block 94 to move when it contacts the surface of the movable block 94. Since the movable seat 7 is hinged on the base 6, the movable seat 7 is forced to flip to one side, thereby pouring the processed paper tube onto the unloading guide plate 17 to achieve automatic unloading.

When the push rod 8 exceeds the position of the movable block 94, the movable block 94 is reset under the elastic force of the spring 93. When the paper tube is moved to the position between the two forming dies 15 by the movable seat 7, the motor 11 is started and drives the bidirectional screw 12 to rotate, and the bidirectional screw 12 drives the two sliders 13 to move, from The two spindle boxes 14 are moved so that the edge rolling mold can clamp the paper tube. At this time, the spindle in the spindle box 14 drives the forming mold 15 to rotate at high speed, and the paper tube also rotates at high speed. Then the cylinder 162 is started to drive the movable plate 163 to move downward, and the movable plate 163 drives the pressure wheel 165 to move downward. The pressure wheel 165 contacts the steel rings at both ends of the paper tube and continues to move, and then grinds the steel rings to form an R-shaped groove to complete the edge rolling work at both ends of the paper tube at the same time. When the paper tube is edge rolled, the paper tube moves downward with the base 6. At this time, the push rod 8 does not push the movable block 94 to move when it contacts the surface of the movable block 94. Since the movable seat 7 is hinged on the base 6, the movable seat 7 is forced to flip to one side, so that the processed paper tube can be poured onto the unloading guide plate 17.
