[0030] Example 1

[0031] Reference Figure 1-5 The present embodiment provides a rotating mechanism, including a cutting assembly 100, including a mounting shell 101, the mounting shell 101 is used to fix and protect the remaining parts of the cutting assembly 100, a motor 102 is fixedly mounted on the top of the mounting shell 101, the motor 102 is fixed on the axis of the mounting shell 101, the output end of the motor 102 is connected to an output shaft 102a, which can provide power for the output shaft 102a, and the rotation of the output shaft 102a can drive the rotating member 103 to rotate in a circle around the output shaft 102a. Since the tool 104 is fixed on the eccentric position of the rotating member 103, the tool 104 will also perform a circular motion around the axis of the mounting shell 101; a driving assembly 200, the driving assembly 200 is a device for driving various movements, including The first driving part 201, as a fixed part of the entire driving assembly 200, can be regarded as the base of the entire device, which can be used to fix the carton and can drive the carton to move longitudinally. The second driving part 202 is fixedly installed on the first driving part 201, and the third driving part 203 is installed on the second driving part 202, which can drive the third driving part 203 to move horizontally. The third driving part 203 is connected to the mounting frame 204, and the mounting frame 204 can be driven to move in the vertical direction through the third driving part 203. The mounting frame 204 is used to fix the cutting assembly 100. Through a series of movements realized by the driving assembly 200, the tool 104 can be driven to complete any cutting trajectory, and then various cutting surfaces can be cut on the carton.

[0032] In this embodiment, the carton needs to be fixed on the first driving unit 201 first, and then the cutting assembly 100 is fixed in the mounting frame 204. The height of the cutting assembly 100 is adjusted by the third driving unit 203 to ensure that the cutter 104 is in contact with the carton and the cutter 104 can accurately cut the carton.

[0034] Example 2

[0035] Reference Figure 2-4 , which is the second embodiment of the utility model, is based on the previous embodiment, and is different from the previous embodiment in that: a housing 101 is provided with a housing space 101a, a T-shaped groove 101b is provided on the top of the housing space 101a, and an annular tooth 101c is provided on the inner wall of the housing 101; a motor 102 is fixedly arranged on the top of the housing 101, the motor 102 is connected to an output shaft 102a, the output shaft 102a extends into the housing space 101a, and a driving gear 102c is provided on the output shaft 102a; a rotating member 103 is provided at one end There is a driven gear 103a, a T-shaped protrusion 103b is provided on the top of the driven gear 103a, a mounting hole 103c is provided at the bottom of the rotating member 103, a spring 103c-1 is provided at the bottom of the mounting hole 103c, and limiting grooves 103d are symmetrically provided on the inner wall of the mounting hole 103c. The limiting grooves 103d include a first vertical section 103d-1, a first horizontal section 103d-2, a second vertical section 103d-3 and a second horizontal section 103d-4; a limiting block 104a is provided at one end of the tool 104, and the other end of the tool 104 is a blade 104b.

[0036] Specifically, the driving gear 102c is meshed with the driven gear 103a. When the driving gear 103a rotates, it will drive the driven gear 103a to rotate. The driven gear 103a is meshed with the annular gear 101c in the mounting housing 101. Since the driven gear 103a is eccentrically arranged, the driven gear 103a can always mesh with the annular gear 101c during the rotation process, so that the driven gear 103a can rotate along the annular gear 101c, and finally the driven gear 103a can achieve circular motion around the driving gear 102c.

[0037] Preferably, the diameter of the accommodating space 101a is consistent with the diameter of the rotating member 103. When the rotating member 103 is placed in the accommodating space 101a, it can ensure that the rotating member 103 is always in a vertical state during rotation and will not tilt. In addition, the T-slot 101b is circumferentially arranged at the top of the accommodating space 101a, and the T-slot 101b is matched with the T-shaped protrusion 103b in shape. When the T-shaped protrusion 103b is embedded in the T-slot 101b, in addition to achieving the purpose of fixing the rotating member 103, it can also constrain the running path of the driven gear 103a to prevent the driven gear 103a from disengaging and the moving state of the rotating member 103.

[0038] Furthermore, the mounting hole 103c is eccentrically arranged, the diameter of the mounting hole 103c is consistent with the diameter of the tool 104, the width of the limiting groove 103d is consistent with the width of the limiting block 104a, and the tool 104 can be fixed by aligning the limiting block 104a with the limiting groove 103d and inserting it.

[0039] In this embodiment, the output shaft 102a is driven to rotate by the motor 102, and when the output shaft 102a drives the driving gear 102c to rotate synchronously, the driven gear 103a meshing with it is rotated, and the driven gear 103a can achieve a circular motion around the driving gear 102c by meshing with the annular gear 101c, thereby causing the tool 104 to perform a circular motion; after the tool 104 is inserted into the mounting hole 103c, the limit block 104a first enters the first vertical section 103d -1, as the tool 104 is continuously pressed, the spring 103c-1 is compressed until the limit block 104a moves to the top of the first vertical section 103d-1. At this time, the tool 104 is rotated clockwise, and the limit block 104a enters the first horizontal section 103d-2. After the tool 104 is rotated 90 degrees, the limit block 104a moves to the end of the first horizontal section 103d-2. Under the push of the compressed spring 103c-1, the tool 104 moves downward, and the limit block 104a enters the The tool 104 is then rotated counterclockwise, and the limit block 104a finally enters the second horizontal section 103d-4. Since the spring 103c-1 is always in a compressed state, the tool 104 can be fixed by the pressure of the spring 103c-1 on the tool 104 and the restriction of the second horizontal section 103d-4. When the tool is worn out after long-term use, it is necessary to replace the tool regularly. At this time, the limit block 104a is rotated clockwise to make the tool 104 fixed. 04a enters the second vertical section 103d-3, then presses the tool 104 and rotates it counterclockwise, the limit block 104a will enter the first horizontal section 103d-2 along the second vertical section 103d-3, until it rotates 90 degrees counterclockwise, the limit block 104a moves to the connection between the first horizontal section 103d-2 and the first vertical section 103d-1, at this time, the tool 104 is pushed by the spring 103c-1 and pops out from the mounting hole 103c, completing the removal of the old tool 104.

[0040] By providing the cutting assembly 100 , not only can the tool 104 be rotated to enrich the moving path of the tool, but also the tool 104 can be quickly disassembled and assembled by providing the mounting hole 103 c .

[0044] Preferably, the fixing plate 202a is fixed on the outside of the base 201a, and a second limiting rod 202c and a second driving rod 202b are connected between the two fixing plates 202a. The second driving rod 202b is also a screw rod, which can be driven to rotate by a second driving motor 202b-1.

[0046] In this embodiment, when the forward and reverse rotation of the first drive motor 201c-1 drives the first drive rod 201c to rotate forward and reverse synchronously, the first drive seat 201b-1 mounted on the first drive rod 201c will reciprocate back and forth, thereby realizing the longitudinal reciprocating motion of the movable plate 201b. Similarly, the forward and reverse rotation of the second drive motor 202b-1 will also cause the second drive rod 202b to rotate forward and reverse, thereby realizing the lateral reciprocating motion of the third drive unit 203.
