In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] Please also read Figure 1 and Figure 2 Now, a single servo driven cutting device provided in an embodiment of the present application is described. The single servo driven cutting device includes a feeding component, a slitting component and a driving mechanism. Among them:

[0029] The feeding assembly includes a traction roller 101 and a first one-way bearing 102 connected to the traction roller 101, and the slitting assembly includes a moving knife 103, a rotating shaft 104 connected to the moving knife 103, and a second one-way bearing 105 connected to the rotating shaft 104, the rotating shaft 104 is parallel to the traction roller 101, and the locking direction of the second one-way bearing 105 is opposite to the locking direction of the first one-way bearing 102. The driving mechanism includes a servo motor 106 capable of forward and reverse rotation and a first synchronous pulley 107 connected to the output end of the servo motor 106, and also includes a second synchronous pulley 108 coaxially mounted on the first one-way bearing 102 and a third synchronous pulley 109 coaxially mounted on the second one-way bearing 105, and the first synchronous pulley 107, the second synchronous pulley 108 and the third synchronous pulley 109 are connected through the same synchronous belt transmission.

[0030] According to the above structure provided in the present embodiment, only a single servo motor 106 is provided in the single servo driven cutting device provided in the present embodiment, and the servo motor 106 can respectively drive the traction roller 101 and the rotating shaft 104 for driving the movable knife 103 to rotate through the first synchronous belt pulley 107, the second synchronous belt pulley 108 and the third synchronous belt pulley 109 which are synchronously connected. Since the second synchronous belt pulley 108 is connected to the traction roller 101 through the first one-way bearing 102, and the third synchronous belt pulley 109 is connected to the traction roller 101 through the second one-way bearing 105, Connected to the rotating shaft 104, the locking directions of the first one-way bearing 102 and the second one-way bearing 105 are opposite, so that the traction roller 101 used for feeding and the movable knife 103 used for slitting can be alternately driven by the servo motor 106 when the servo motor 106 rotates forward and reversely. In this way, not only can the technical effect of a single motor driving the traction roller 101 and the movable knife 103 be achieved, which greatly simplifies the mechanical structure and control system of the cutting device, but also the traction roller 101 and the movable knife 103 can form a more stable fit and achieve a better cutting effect, which is far superior to the existing technology.

[0031] In order to facilitate the explanation of the operating principle of the single servo-driven cutting device provided in this embodiment, this embodiment is explained by taking the example that the servo motor 106 drives the traction roller 101 when rotating forward and drives the rotating shaft 104 when rotating reversely. It can be understood that the servo motor 106 drives the rotating shaft 104 when rotating forward and drives the traction roller 101 when rotating reversely has the same principle, which will not be repeated in this embodiment.

[0032] When the servo motor 106 rotates forward and drives the traction roller 101 to operate, the first one-way bearing 102 connected between the second synchronous pulley 108 and the traction roller 101 is in a locked state. Since the locking direction of the second one-way bearing 105 is opposite to the locking direction of the first one-way bearing 102, the second one-way bearing 105 is in a free rotation state at this time. In this way, the second one-way bearing 105 connected between the third synchronous pulley 109 and the rotating shaft 104 cannot transmit power, and the servo motor 106 cannot drive the moving knife 103 to perform slitting operations, while the traction roller 101 can be used for continuous feeding under the drive of the servo motor 106.

[0033] When the servo motor 106 reverses, the first one-way bearing 102 switches to a free-rotating state and the second one-way bearing 105 switches to a locked state, so that the first one-way bearing 102 connected between the second synchronous pulley 108 and the traction roller 101 cannot transmit power, while the second one-way bearing 105 in a locked state can transmit the power of the servo motor 106 to the movable knife 103 through the rotating shaft 104 and perform a slitting operation. Usually, the servo motor 106 drives the rotating shaft 104 to rotate one circle, and the movable knife 103 completes a cutting and rises to the reset position. At this time, the movable knife 103 is away from the fixed knife 115 and has a distance for the material to pass. At the same time, the traction roller 101 that stops rotating during cutting can also keep the traction material in place and facilitate the smooth slitting operation. It can be understood that in the actual cutting process, the servo motor 106 can flexibly set the forward and reverse time of the servo motor 106 according to the specifications and dimensions of the slitting and the actual time required for the movable knife 103 to slitting the material, which has a flexible adjustment effect and can adapt to more cutting scenes.

[0034] In another embodiment of the present application, please refer to Figure 1 and Figure 2The slitting assembly also includes an eccentric wheel 110 mounted on the rotating shaft 104 and a pull rod 111 connected to the eccentric wheel 110. The end of the pull rod 111 away from the eccentric wheel 110 is connected to a joint bearing 112. The servo motor 106 is sequentially connected to the movable knife 103 through the rotating shaft 104, the eccentric wheel 110, the pull rod 111 and the joint bearing 112 and is used to drive the movable knife 103 to move back and forth. According to the above structure provided in this embodiment, when the rotating shaft 104 rotates under the drive of the servo motor 106, the eccentric wheel 110 connected to the rotating shaft 104 can be driven to rotate, thereby driving the movable knife 103 connected to the pull rod 111 to move back and forth through the pull rod 111 and complete the slitting operation, which has a stable driving effect. In addition, the joint bearing 112 connected to the pull rod 111 can also well avoid the mechanical interference between the pull rod 111 and the movable knife 103, which is conducive to the single servo drive cutting device provided in this embodiment to operate stably for a long time.

[0035] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The slitting assembly further includes a wall panel 113 for mounting the rotating shaft 104, a vertical panel 114 connected to the wall panel 113, a fixed knife 115 connected to the vertical panel 114, and a moving knife seat 116 for mounting the moving knife 103. The moving knife seat 116 is slidably connected to the wall panel 113 and is used to drive the moving knife 103 to approach or move away from the fixed knife 115. According to the above structure provided in this embodiment, the moving knife 103 is mounted on the moving knife seat 116 to have a better stable mounting effect. By setting the moving knife seat 116 to be slidably connected to the vertical panel 114, the moving process of the moving knife 103 relative to the fixed knife 115 can be made more stable, which is conducive to achieving a better cutting effect of the single servo-driven cutting device provided in this embodiment.

[0036] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The slitting assembly further includes a linear rail 117 connected to the vertical plate 114 and extending toward the fixed knife 115, and the movable knife seat 116 is slidably connected to the linear rail 117 and provided with a sliding guide by the linear rail 117. According to the above structure provided in this embodiment, the linear rail 117 connected to the vertical plate 114 can provide a more stable sliding guide for the movable knife seat 116, which is conducive to further improving the cutting effect of the single servo driven cutting device in this embodiment.

[0037] In another embodiment of the present application, please refer to Figure 1 and Figure 2, the vertical plate 114 is arranged between the traction roller 101 and the moving knife 103 and has a perforation 118 for the material to pass through, and the slitting assembly also includes a guide roller mounting plate 119 arranged side by side with the vertical plate 114 and a guide roller 120 rotatably connected to the guide roller mounting plate 119, and the installation position of the guide roller 120 corresponds to the perforation 118 and is used to carry the material. According to the above structure provided in this embodiment, the guide roller 120 arranged on the guide roller mounting plate 119 can send the material from the traction roller 101 to the position where the moving knife 103 is located in a posture that is more suitable for the moving knife 103, which is conducive to further improving the cutting effect of the single servo-driven cutting device in this embodiment.

According to the above structure provided in this embodiment, the guide roller 120 mounting seat movably connected to the archway 121 can drive the guide roller 120 connected to the guide roller 120 mounting seat to move relative to the perforation 118 provided on the vertical plate 114 during the adjustment process relative to the archway 121, so that the position of the guide roller 120 can be more adapted to the position of the perforation 118 and achieve a better feeding effect, which is conducive to further improving the cutting effect of the single servo-driven cutting device in this embodiment.

[0039] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The feeding assembly further includes a pressure roller 122 rotatably mounted on the arch 121 and parallel to the traction roller 101. According to the above structure provided in this embodiment, the pressure roller 122 mounted on the arch 121 can cooperate with the traction roller 101 to form a better feeding effect, which is conducive to further improving the cutting effect of the single servo driven cutting device in this embodiment.
