[0030] In addition, the technical features involved in different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0031] Please refer to Figure 1 , an embodiment of the present disclosure provides a fixing device 100 for pipe processing, including a rotary driving mechanism 10, a main shaft 20, a mounting plate 30, a telescopic driving mechanism 40, a sliding sleeve 50 and at least two clamping mechanisms 60; the mounting plate 30 is arranged on the main shaft 20, the clamping mechanisms 60 are slidably arranged on the mounting plate 30, and the sliding sleeve 50 is slidably sleeved on the main shaft 20; the rotary driving mechanism 10 is in transmission connection with the main shaft 20 to drive the main shaft 20 to rotate; the telescopic driving mechanism 40 is in transmission connection with each of the clamping mechanisms 60 through the sliding sleeve 50 to drive each of the clamping mechanisms 60 to approach or move away from each other.

[0032] In the fixing device 100 for pipe processing of this embodiment, the workpiece in the pipe processing operation can be a paper tube. Through the drive of the telescopic driving mechanism 40, each clamping mechanism 60 can clamp and fix the paper tube, and through the drive of the rotary driving mechanism 10, the main shaft 20 can drive the mounting plate 30, the clamping mechanisms 60 and the paper tube to rotate. In this way, the cutting operation of the paper tube can be realized, and phenomena such as displacement or falling off of the paper tube during the paper tube cutting operation can be avoided.

[0033] Please refer to together Figure 2 and Figure 3In one embodiment, a strip hole 52 is provided on the sliding sleeve 50, and the strip hole 52 and the main shaft 20 form a preset angle, that is, one end of the strip hole 52 extends in a direction close to the main shaft 20, and the other end of the strip hole 52 extends in a direction away from the main shaft 20, and the central axis of the main shaft 20 and the hole center line of the strip hole 52 are in the same plane; each of the clamping mechanisms 60 includes a first slider 62, a clamping head 64, a connecting block 66 and a transmission shaft 68; the first slider 62 is slidably arranged on the mounting plate 30, the clamping head 64 is arranged on the first slider 62, the transmission shaft 68 is movably inserted in the strip hole 52, and the transmission shaft 68 is connected to the first slider 62 through the connecting block 66; the telescopic driving mechanism 40 is connected to each other through the sliding sleeve 50, the transmission shaft 68, the connecting block 66, the first slider 62 and each of the clamping heads 64 to drive each of the clamping heads 64 to move closer to or away from each other. Specifically, there are three clamping mechanisms 60, and the clamping heads 64 can be made of rubber or other materials. The transmission shaft 68 is inserted into the strip hole 52, and the transmission shaft 68 can move relatively along the length direction of the strip hole 52. When the telescopic driving mechanism 40 drives the sliding sleeve 50 to slide along the axial direction of the main shaft 20, due to the cooperation between the strip hole 52 and the transmission shaft 68, the sliding sleeve 50 can drive the clamping heads 64 to move closer to or away from each other through the connecting block 66, so that the paper tube can be clamped.

[0034] In one embodiment, the mounting plate 30 is provided with a strip through hole 32, the strip through hole 32 is distributed along the radial direction of the mounting plate 30, the first slider 62 and the clamping head 64 are arranged on one side of the mounting plate 30, the connecting block 66 passes through the strip through hole 32, and the sliding sleeve 50 and the transmission shaft 68 are located on the side of the mounting plate 30 away from the first slider 62 and the clamping head 64. When the clamping heads 64 approach or move away from each other, the connecting block 66 moves along the length direction of the strip through hole 32, that is, moves along the radial direction of the mounting plate 30, so that each clamping head 64 can be driven to approach or move away from each other. The mounting plate 30 can be a disk, and each clamping mechanism 60 is arranged around the center of the disk. If the mounting plate 30 is not a disk, the projection of the spindle 20 on the mounting plate 30 is the center of the circle, and each clamping mechanism 60 is arranged around the center of the circle.

[0035] In one embodiment, each of the clamping mechanisms 60 further includes a first slide rail 69, which is disposed on the mounting plate 30, and the first slider 62 is disposed on the corresponding first slide rail 69. The cooperation between the first slide rail 69 and the first slider 62 makes the sliding of the clamping head 64 smoother.

[0036] In one embodiment, the fixing device 100 for pipe processing further includes a positioning block 70. The positioning block 70 is provided on the mounting plate 30, and the positioning block 70 and each clamping mechanism 60 are located on the same surface of the mounting plate 30. Since the middle part of the paper tube is a hollow structure, when the paper tube approaches the mounting plate 30, the positioning block 70 extends into the middle part of the paper tube, so that the positioning block 70 can position and limit the paper tube from the inside of the paper tube.

[0037] In one embodiment, the fixing device 100 for pipe processing further includes a base 80. The rotation driving mechanism 10, the telescopic driving mechanism 40 and the main shaft 20 are provided on the base 80, and the main shaft 20 is rotatably arranged. By providing the base 80, the integrity of the fixing device 100 for pipe processing is better, which is convenient for handling.

[0038] In one embodiment, the telescopic driving mechanism 40 includes a telescopic driving element 42, a second slider 44, a second slide rail 46 and a pulley 48. The telescopic driving element 42 and the second slide rail 46 are provided on the base 80. The second slider 44 is slidably arranged on the second slide rail 46. The pulley 48 is sleeved on the second slider 44. The sliding sleeve 50 is further provided with a limiting groove 54 along its circumferential direction, and the pulley 48 is clamped in the limiting groove 54. The telescopic driving element 42 can be a cylinder. The telescopic driving element 42 drives the second slider 44, and the second slider 44 drives the pulley 48. Due to the provision of the limiting groove 54, the sliding sleeve 50 and the pulley 48 cannot be separated from each other, but can rotate relative to each other. The telescopic driving element 42 can drive the clamping heads 64 to approach or move away from each other in sequence through the second slider 44, the pulley 48, the sliding sleeve 50, the transmission shaft 68 and the connecting block 66. When the rotation driving mechanism 10 drives the main shaft 20 to rotate, the main shaft 20 drives the sliding sleeve 50 and the mounting plate 30 to rotate synchronously. Since the clamping heads 64 and the like are provided on the mounting plate 30, the paper tube can be driven to rotate.

[0039] In one embodiment, one end of the second slider 44 is slidably arranged on the second slide rail 46, and the other end of the second slider 44 is hinged to the pulley 48. Since the second slider 44 and the pulley 48 are hinged to each other, a certain inclination angle between the second slider 44 and the pulley 48 can be adapted, which does not affect the axial movement of the pulley 48 along the main shaft 20.

[0040] When cutting a paper tube, the paper tube is generally first sleeved on the mounting shaft to achieve preliminary fixation of the paper tube. In one embodiment, the fixing device 100 for tube processing further includes a positioning rod 90, a first mounting hole 22 is provided in the spindle 20, the first mounting hole 22 is arranged along the axial direction of the spindle 20, a second mounting hole 34 is further provided in the middle of the mounting plate 30, and the second mounting hole 34 is connected to the first mounting hole 22; one end of the positioning rod 90 is fixedly connected to the base 80, and the other end of the positioning rod 90 passes through the first mounting hole 22 and the second mounting hole 34 in sequence and extends to the mounting plate 30. By providing the positioning rod 90, when the mounting shaft and the mounting plate 30 are close to each other, the other end of the positioning rod 90 can support the center of the mounting shaft, which is also conducive to fixing the paper tube.

[0041] In one embodiment, the rotary drive mechanism 10 includes a rotary drive element 12 and a pulley transmission assembly 14, wherein the rotary drive element 12 is disposed on the base 80, and the rotary drive element 12 is connected to the main shaft 20 through the pulley transmission assembly 14 to drive the main shaft 20 to rotate. The rotary drive element 12 may be a motor, and the pulley transmission assembly 14 may be a belt transmission mechanism including two pulleys and a belt, and the main shaft 20 and the motor are respectively provided with a pulley, and the belt is sleeved on the two pulleys, so that the motor can drive the main shaft 20 to rotate.
