It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a paper core cutting device for cutting paper cores, including a machine frame 1. A movable frame 2 is slidably arranged on the top of the machine frame 1. A support platform 4 is arranged on the inner side of the movable frame 2. A cutting component 6 is fixedly installed at one end of the support platform 4. A paper core fixing mechanism 7 is slidably connected to the support platform of the machine frame 1. The paper core fixing mechanism 7 includes a base 71 and a bottom plate 72. A partition plate 73 is fixedly installed at the bottom of the base 71 and is inserted into the interior of the bottom plate 72. A turntable 74 is arranged on one side of the base 71. Two turntables 74 are symmetrically arranged. A clamping rod 75 is slidably connected inside the turntable 74. An arc-shaped slot 76 is provided at the junction of the turntable 74 and the clamping rod 75. A worm gear 77 is fixedly connected to one side of the turntable 74. The worm gear 77 is located on the outside of the base 71. A worm 78 is rotatably installed on the outer wall of the base 71. The worm 78 is meshed with the worm gear 77. A connecting rod 3 is detachably connected to the inside of the movable frame 2. One end of the connecting rod 3 is fixedly connected to the support platform 4. A motor and belt drive assembly 5 is fixedly installed on the upper surface of the support platform 4. The output end of the motor and belt drive assembly 5 is fixedly connected to the blade of the cutting assembly 6.
[0023] The specific settings and functions of this embodiment are described in detail below. The movable frame 2 sliding on the top of the equipment frame 1 can drive the inner support platform 4 to move. The support platform 4 is connected to the movable frame 2 through a detachable connecting rod 3. The motor and belt drive assembly 5 on the support platform 4 drive the blade of the cutting assembly 6 to rotate. At the same time, the paper core fixing mechanism 7 sliding on the support platform of the equipment frame 1 can be adjusted to cooperate with the cutting. In the paper core fixing mechanism 7, the base 71 is inserted into the top of the bottom plate 72. The clamping rod 75 sliding in the turntable 74 symmetrically arranged inside it can be adjusted in position through the arc-shaped slot 76. The worm gear 77 on the outer side of the turntable 74 meshes with the worm 78 rotatably installed on the outer wall of the base 71. Rotating the worm 78 can drive the worm gear 77 and the turntable 74 to rotate, so that the clamping rod 75 clamps the paper core under the constraint of the arc-shaped slot 76. After being fixed, the paper core moves to the cutting assembly 6 along with the paper core fixing mechanism 7. The movable frame 2 drives the support platform 4 and the cutting assembly 6 to move, and the cutting is completed by the rotating blade. The sliding design of the movable frame 2 and the paper core fixing mechanism 7 can flexibly adjust the cutting position. The connecting rod 3 is detachable for easy maintenance of the support platform 4. The motor and belt drive assembly 5 provide stable power to the cutting assembly 6 to ensure cutting efficiency. In the paper core fixing mechanism 7, the meshing transmission of the worm 78 and the worm wheel 77 can accurately control the rotation of the turntable 74. The clamping rod 75 is guided by the arc-shaped strip hole 76 to stably clamp the paper core. The symmetrically arranged turntable 74 ensures the fixed balance. The plug-in structure of the base 71 and the bottom plate 72 facilitates disassembly and assembly. The whole device achieves accurate fixing and efficient cutting of the paper core. The coordinated work of each component improves the adaptability and ease of operation of the device.
[0024] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a lead screw drive assembly 711 is threadedly connected to the bottom of the base plate 72. One end of the lead screw drive assembly 711 is rotatably connected to the equipment frame 1. A limit rod 710 is inserted inside the base plate 72. The limit rod 710 passes through the partition plate 73. One end of the clamping rod 75 is fixedly connected to a rotating rod 79. The rotating rod 79 is rotatably installed on one side of the base 71.
[0025] The overall effect of this embodiment is that one end of the screw drive assembly 711, which is threaded to the bottom of the base plate 72, is rotatably connected to the equipment frame 1. Rotating the screw drive assembly 711 can drive the base plate 72 and the base 71 above it to move along the equipment frame 1. The limiting rod 710 inserted inside the base plate 72 passes through the partition plate 73. The partition plate 73 is slidably connected to the equipment frame 1 and plays a guiding and limiting role in the movement of the base 71. The rotating rod 79, which is fixed at one end of the clamping rod 75, is rotatably installed on one side of the base 71. The clamping rod 75 swings stably around the rotating rod 79 as it rotates with the turntable 74, ensuring the accuracy of the clamping action. The threaded connection between the lead screw drive assembly 711 and the base plate 72 enables the smooth movement of the paper core fixing mechanism 7. The limit rod 710 improves the movement accuracy, and the rotating rod 79 enhances the stability of the clamping rod 75's movement, preventing clamping deviation. The coordinated operation of these components improves the adjustment accuracy and operational stability of the device, facilitating precise control of the position of the paper core fixing mechanism 7 and the movement of the clamping rod 75, thus optimizing the cutting effect.
[0026] The method of use and working principle of this device: Place the paper core between the two symmetrical turntables 74 of the paper core fixing mechanism 7, rotate the worm 78 on the outer wall of the base 71 so that it meshes with the worm wheel 77 to drive the turntable 74 to rotate. The clamping rod 75 swings stably and clamps the paper core under the constraint of the arc-shaped slot 76 and the rotation support of the rotating rod 79 at one end. Rotate the screw transmission assembly 711 connected to the equipment frame 1 so that the base plate 72 drives the base 71 and the fixed paper core to move along the equipment frame 1 to a suitable cutting position. The movable frame 2 slides on the top of the equipment frame 1, driving the support platform 4 connected by the connecting rod 3 to move. At the same time, start the motor and belt transmission assembly 5 on the support platform 4 to drive the blade of the cutting assembly 6 to rotate. The movable frame 2 continues to drive the cutting assembly 6 to move so that the rotating blade cuts the paper core. After completion, turn off the motor and belt transmission assembly 5, rotate the worm 78 in the opposite direction to release the clamping rod 75, and remove the cut paper core.
