In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The embodiment of the utility model provides a slitting device, including a mounting seat 10, a first knife group 20, a second knife group 30, a driving mechanism 40 and a buffer assembly 50; the first knife group 20 is assembled on the mounting seat 10, and the first knife group 20 and the second knife group 30 are spaced apart along a first direction to form an accommodating space for accommodating materials; one end of the driving mechanism 40 is connected to the second knife group 30 through the buffer assembly 50, and is used to drive the second knife group 30 to move along the first direction, so that the second knife group 30 cooperates with the first knife group 20 to cut or not cut the material.

[0036] As an example, the slitting device includes a mounting seat 10, a first knife group 20, a second knife group 30, a driving mechanism 40 and a buffer assembly 50. The first knife group 20 is fixedly mounted on the mounting seat 10 and can be an ultrasonic knife group. The first knife group 20 and the second knife group 30 can be arranged at intervals in a first direction, such as a vertical direction or a horizontal direction, to form a storage space for accommodating materials. One end of the driving mechanism 40 is connected to the second knife group 30 in a transmission manner. When the slitting device is working, the driving mechanism 40 controls the second knife group 30 to move in the first direction toward the first knife group 20 until the two sides of the material are respectively in contact with the first knife group 20 and the second knife group 30, so that the first knife group 20 and the second knife group 30 cut the material. After that, the driving mechanism 40 controls the second knife group 30 to move in the first direction away from the first knife group 20, so that the cut material can move smoothly in the storage space to prepare for the next slitting. In this example, the driving mechanism 40 only needs to control the movement of the second knife group 30 to complete the cutting action of the material, and the control scheme is simple. A buffer assembly 50 is also provided between the second knife group 30 and the driving mechanism 40, for alleviating the impact of the slitting operation on the second knife group 30 and the first knife group 20. The buffer assembly 50 between the second knife group 30 and the driving mechanism 40 can buffer and absorb the collision force between the first knife group 20 and the second knife group 30 when the first knife group 20 and the second knife group 30 abut and cut the material between the first knife group 20 and the second knife group 30, so as to alleviate the impact of the slitting operation on the second knife group 30 and the first knife group 20, and prevent the knife groups from being damaged and aging too quickly.

[0037] In this example, by providing a buffer assembly 50 between the second knife assembly 30 and the driving mechanism 40, the impact of the slitting operation on the second knife assembly 30 and the first knife assembly 20 can be alleviated, thereby preventing the knife assembly from being damaged and aging too quickly.

[0038] In one embodiment, the buffer assembly 50 includes a support seat 51 and a spring 52 assembled on the support seat 51 ; the support seat 51 is connected to the driving mechanism 40 , and the spring 52 is connected to the second knife assembly 30 .

[0039] As an example, the buffer assembly 50 includes a support seat 51 and a spring 52 mounted on the support seat 51. The support seat 51 is connected to the driving mechanism 40, and is used to move along the first direction away from or close to the first knife group 20 under the drive of the driving mechanism 40. The spring 52 is connected to the second knife group 30. When the first knife group 20 and the second knife group 30 abut and cut the material between the first knife group 20 and the second knife group 30, the collision force between the first knife group 20 and the second knife group 30 can be converted into a compression force on the spring 52, and the collision force is absorbed and resolved, thereby alleviating the impact of the cutting operation on the second knife group 30 and the first knife group 20, and preventing the knife groups from being damaged and aging too quickly.

[0040] In one embodiment, the slitting device further includes a guide rail 60 disposed on the mounting seat 10 along the first direction; the buffer assembly 50 and the second knife assembly 30 are both slidably connected to the guide rail 60 .

[0041] As an example, the slitting device also includes a guide rail 60 fixedly installed on the mounting seat 10 along a first direction, such as a vertical direction. The second knife group 30 and the support seat 51 in the buffer assembly 50 are both slidably connected to the guide rail 60. The guide rail 60 plays a guiding role, so that the second knife group 30 can be driven by the driving mechanism 40 along the guiding direction of the guide rail 60 to approach the first knife group 20 and complete the slitting of the material.

[0042] In one embodiment, the driving mechanism 40 includes an eccentric wheel driving assembly 41 and a rocker arm 42; the eccentric wheel driving assembly 41 is assembled on the mounting base 10; one end of the rocker arm 42 is transmission-connected to the eccentric wheel driving assembly 41, and the other end of the rocker arm 42 is connected to the second knife group 30 through the buffer assembly 50; the eccentric wheel driving assembly 41 is used to drive the rocker arm 42 to swing so that the second knife group 30 moves along the first direction.

[0043] As an example, the driving mechanism 40 includes an eccentric wheel driving assembly 41 and a swing rod 42. The eccentric wheel driving assembly 41 is assembled on the mounting seat 10. In the eccentric wheel driving assembly 41, the outer edge of the eccentric wheel 412 connected to the driving motor 411 is connected to one end of the swing rod 42 by a rotating pair, and the other end of the swing rod 42 is connected to the second knife group 30 through the buffer assembly 50.

[0044] During the operation of the driving mechanism 40, the eccentric wheel 412 in the eccentric wheel driving assembly 41 rotates, driving the swing rod 42 connected to the eccentric wheel 412 to swing. During the swinging process, the swing rod 42 pushes the second knife group 30 to reciprocate along the first direction on the guide rail 60 to complete the cutting operation.

[0045] In one embodiment, the eccentric wheel driving assembly 41 includes a driving motor 411 and an eccentric wheel 412 ; the output shaft of the driving motor 411 is connected to the inner hole of the eccentric wheel 412 , and the eccentric wheel 412 is drivingly connected to the rocker rod 42 .

[0046] As an example, the eccentric wheel driving assembly 41 includes a driving motor 411 and an eccentric wheel 412. The driving motor 411 is mounted on the mounting seat 10. The output shaft of the driving motor 411 is connected to the inner hole of the eccentric wheel 412 to drive the eccentric wheel 412 to rotate. The outer edge of the eccentric wheel 412 is connected to one end of the swing rod 42 by a rotating pair. When the eccentric wheel 412 rotates, the swing rod 42 also swings accordingly.

[0047] In one embodiment, the driving mechanism 40 further includes a position sensor 43 ; the position sensor 43 is mounted on the driving motor 411 and is used to detect the position of the eccentric wheel 412 , so that the driving mechanism 40 adjusts the rotational motion according to the position.

[0048] As an example, the driving mechanism 40 further includes a position sensor 43, which may be a photoelectric sensor, etc. The position sensor 43 is mounted on the driving motor 411 and is used to detect the rotation position of the eccentric wheel 412 to determine whether the swing arm 42 pushes the second knife group 30 to the highest point. Specifically, the position sensor 43 can transmit the detected position information to the control unit of the device where the driving motor 40 is located. The control unit combines the position information and the information detected by other devices in the device to control and adjust the rotation action of the driving mechanism 40, so that when the driving mechanism 40 drives the swing arm 42 to push the second knife group 30 to the highest point, the preset cutting position of the material can be cut.

[0049] In one embodiment, the driving mechanism 40 also includes a worm wheel 44, a worm 45 and an adjustment handle; the rocker arm 42 is connected to the buffer assembly 50 through a camshaft 46, the worm wheel 44 is assembled on the camshaft 46, the worm 45 is assembled on the mounting seat 10, and is connected to the worm wheel 44 in transmission; the adjustment handle is assembled on the worm 45, and is used to drive the worm 45 to rotate so that the worm wheel 44 rotates, so as to change the assembly position of the buffer assembly 50 and the second knife group 30 on the rocker arm 42.

[0050] As an example, the driving mechanism 40 further includes a worm wheel 44, a worm 45 and an adjustment handle. The swing rod 42 is connected to the cam segment of the cam shaft 46 by a rotating pair, and both ends of the cam shaft 46 are inserted into the buffer assembly 50 to form a transmission connection structure between the swing rod 42 and the buffer assembly 50. The worm wheel 44 is assembled on the cam shaft 46, and the worm 45 is assembled on the mounting seat 10 and is transmission-connected with the worm wheel 44. The adjustment handle is assembled on the worm 45, which can drive the worm 45 to rotate, thereby driving the worm wheel 44 to rotate, so as to change the direction of the cam of the cam shaft 46, thereby changing the assembly position of the buffer assembly 50 and the second knife group 30 on the swing rod 42. In this example, by setting the worm wheel 44 and the worm 45, it is convenient to adjust the cam direction of the cam shaft 46, change the effective length of the swing rod 42, and adjust the assembly position of the buffer assembly 50 and the second knife group 30 on the swing rod 42 to adapt to different cutting conditions. At the same time, the structure in which the worm wheel 44 and the worm 45 cooperate with each other is self-locking. After the worm 45 is rotated for adjustment, the worm wheel 44 will no longer rotate. Therefore, unless adjusted by the second adjustment handle, the direction of the cam on the camshaft 46 will no longer change. The structure in which the worm wheel 44 and the worm 45 cooperate with each other also has the characteristic of relatively large transmission, which is more labor-saving during adjustment. The worm 45 is small in size and can save installation space.

[0051] In one embodiment, the first knife group 20 includes an ultrasonic component 21 and a first knife head 22; the ultrasonic component 21 is assembled on the mounting base 10, and the first knife head 22 is assembled on the ultrasonic component 21 along the first direction, and is spaced apart from the second knife group 30 in the first direction, forming a accommodating space for accommodating materials with the second knife group 30.

[0052] As an example, the first knife group 20 includes an ultrasonic component 21 and a first knife head 22. The ultrasonic component 21 is mounted on the mounting seat 10, and the first knife head 22 is mounted on the ultrasonic component 21 along a first direction, such as a vertical direction, and is spaced apart from the second knife group 30 in the first direction, and forms a storage space for accommodating materials with the second knife group 30. The ultrasonic component 21 can generate high-frequency vibration, thereby driving the first knife head 22 to vibrate at a high frequency. When the second knife group 30 approaches the first knife group 20, the first knife head 22 and the second knife group 30 abut, and the high-frequency vibration of the first knife head 22 can cut the material between the first knife group 20 and the second knife group 30. By setting the ultrasonic component 21 to generate high-frequency vibration at the first knife head 22, a better cutting effect can be achieved for some special materials, especially for materials with relatively soft materials, so that the incision is smooth and will not cause deformation, warping, fluffing, or threading.

[0053] In one embodiment, the second knife group 30 includes a second knife head 31; the second knife head 31 is assembled on the buffer assembly 50 along the first direction and is arranged opposite to the first knife group 20 in the first direction to form a containing space for accommodating materials with the first knife group 20.

[0054] As an example, the second knife group 30 includes a second knife head 31, which is assembled on the buffer assembly 50 along a first direction, such as a vertical direction, and is spaced apart from the first knife group 20 in the first direction to form an accommodating space for accommodating materials.

[0055] The embodiment of the utility model further provides a label making device, comprising a machine platform and a slitting device in any of the above embodiments arranged on the machine platform, wherein the slitting device is used for cutting or not cutting materials.

[0056] As an example, the label making device includes a machine and the slitting device in the above example, and the slitting device is used to cut the material transmitted in the label making device. In this example, by providing a buffer component 50 between the second knife group 30 and the driving mechanism 40 in the slitting device, the impact of the slitting operation on the second knife group 30 and the first knife group 20 can be alleviated, preventing the knife groups from being damaged and aging too quickly.
