[0045] In one embodiment, the material unloading mechanism 80 further includes an elastic element 89, which is disposed between the material unloading push plate 86 and the third telescopic drive assembly 82. By providing the elastic element 89, a certain buffer exists when the material unloading push plate 86 and the first sliding sleeve 88 contact, thereby avoiding rigid contact between the material unloading push plate 86 and the first sliding sleeve 88, and avoiding damage to the material unloading push plate 86 and the first sliding sleeve 88. The elastic element 89 may be a spring.

[0046] Please refer to Figure 5 and Figure 6 In one embodiment, the fixing mechanism 20 includes a second rotation drive component 21, a main shaft 22, a mounting plate 23, a fifth telescopic drive component 24, a second sleeve 25 and at least two clamping components 26; the mounting plate 23 is arranged on the main shaft 22, the clamping component 26 is slidably arranged on the mounting plate 23, and the second sleeve 25 is slidably arranged on the main shaft 22; the second rotation drive component 21 is connected to the main shaft 22 by transmission to drive the main shaft 22 to rotate; the fifth telescopic drive component 24 is connected to each of the clamping components 26 by transmission through the second sleeve 25 to drive each of the clamping components 26 to move closer to or away from each other.

[0047] By driving the fifth telescopic driving component 24, each clamping component 26 can clamp and fix the paper tube 101. By driving the second rotating driving component 21, the main shaft 22 can drive the mounting plate 23, the clamping component 26 and the paper tube 101 to rotate. In this way, the cutting operation of the paper tube 101 can be realized, and the phenomenon of paper tube 101 shifting or falling off during the cutting operation can be avoided.

[0048] In one embodiment, a strip hole 252 is formed on the second sleeve 25, and the strip hole 252 and the main shaft 22 form a preset angle, that is, one end of the strip hole 252 extends in a direction close to the main shaft 22, and the other end of the strip hole 252 extends in a direction away from the main shaft 22, and the central axis of the main shaft 22 and the hole center line of the strip hole 252 are in the same plane; each of the clamping components 26 includes a first slider 262, a clamping head 264, a connecting block 266 and a transmission shaft 268; the first slider 262 The fifth telescopic drive assembly 24 is sequentially connected to each of the clamping heads 264 through the second sleeve 25, the transmission shaft 268, the connection block 266, the first slider 262 and the clamping heads 264 to drive each of the clamping heads 264 closer to or farther from each other. Specifically, there are three clamping assemblies 26, and the clamping heads 264 can be made of rubber or other materials. The transmission shaft 268 is inserted into the strip hole 252, and the transmission shaft 268 can move relatively along the length direction of the strip hole 252. When the fifth telescopic driving assembly 24 drives the second sliding sleeve 25 to slide axially along the main shaft 22, due to the cooperation between the strip hole 252 and the transmission shaft 268, the second sliding sleeve 25 can drive each clamping head 264 to move closer to or away from each other through the connecting block 266, so that the paper tube 101 can be clamped.

[0049] In one embodiment, the mounting plate 23 is provided with a strip-shaped through hole 232, and the strip-shaped through hole 232 is distributed along the radial direction of the mounting plate 23. The first slider 262 and the clamping head 264 are arranged on one side of the mounting plate 23, and the connecting block 266 passes through the strip-shaped through hole 232. The second sliding sleeve 25 and the transmission shaft 268 are located on the side of the mounting plate 23 away from the first slider 262 and the clamping head 264. When the clamping heads 264 approach or move away from each other, the connecting block 266 moves along the length direction of the strip-shaped through hole 232, that is, moves along the radial direction of the mounting plate 23, so that each clamping head 264 can be driven to approach or move away from each other. The mounting plate 23 can be a disk, and each clamping assembly 26 is arranged around the center of the disk. If the mounting plate 23 is not a disk, the projection of the main shaft 22 on the mounting plate 23 is the center of the circle, and each clamping assembly 26 is arranged around the center of the circle.

[0050] In one embodiment, each of the clamping assemblies 26 further includes a first slide rail 269, which is disposed on the mounting plate 23, and the first slider 262 is disposed on the corresponding first slide rail 269.

Since the middle of the paper tube 101 is a hollow structure, when the paper tube 101 is close to the mounting plate 23, the positioning block 27 extends into the middle of the paper tube 101, so that the positioning block 27 can position and limit the paper tube 101 from the inside of the paper tube 101.

The telescopic driving element 242 can be a cylinder, which drives the second slider 244, and the second slider 244 drives the pulley 248. Due to the setting of the limit groove 254, the second sleeve 25 and the pulley 248 cannot be separated from each other, but can rotate relative to each other. The telescopic driving element 242 can drive each clamping head 264 to approach or move away from each other through the second slider 244, the pulley 248, the second sleeve 25, the transmission shaft 268, and the connecting block 266 in sequence, and when the second rotating drive component 21 drives the main shaft 22 to rotate, the main shaft 22 drives the second sleeve 25 and the mounting plate 23 to rotate synchronously. Since the clamping head 264 and the like are arranged on the mounting plate 23, the paper tube 101 can be driven to rotate.

[0054] In one embodiment, one end of the second slider 244 is slidably disposed on the second slide rail 246, and the other end of the second slider 244 is hingedly connected to the pulley 248. Since the second slider 244 and the pulley 248 are hingedly connected, a certain tilt angle between the second slider 244 and the pulley 248 can be accommodated without affecting the axial movement of the pulley 248 along the main shaft 22.

[0055] In one embodiment, a cylinder assembly 12 is further provided on the base 10, and a fixing mechanism 20 is arranged on 12, or the cylinder assembly 12 and the fixing mechanism 20 are transmission-connected to drive the fixing mechanism 20 to approach or move away from the first installation axis 34 / the second installation axis 36 / the third installation axis 38.

By providing the positioning rod 28, when the first mounting shaft 34 / the second mounting shaft 36 / the third mounting shaft 38 and the mounting plate 23 are close to each other, the other end of the positioning rod 28 can support the center of the first mounting shaft 34 / the second mounting shaft 36 / the third mounting shaft 38, which is also conducive to fixing the paper tube 101.

[0057] In one embodiment, the second rotation drive assembly 21 includes a rotation drive element 212 and a pulley transmission mechanism 214. The rotation drive element 212 is disposed on the base 10. The rotation drive element 212 is connected to the main shaft 22 through the pulley transmission mechanism 214 to drive the main shaft 22 to rotate.
