The coil assembly 20 is installed on the frame 10, and is used to roll up the material. The coil assembly 20 has two groups of detachable winding parts, and the winding parts are rotatably installed on the coil assembly 20; the auxiliary roller changing assembly 30 is slidably installed on the frame 10. After one group of winding parts completes winding, the auxiliary roller changing assembly 30 slides toward the direction close to the coil assembly 20 to abut against the material, thereby assisting the two groups of winding parts to work alternately; the cutting assembly 40 is installed on the frame 10, and the cutting assembly 40 has a cutting part, which cuts the material along a preset direction; the winding part of the transfer assembly 50 cancels the installation with the coil assembly 20, and transfers the material to the transfer assembly 50 along the rotation center of the winding part, and the transfer assembly 50 transports and stacks the material.

[0029] In this embodiment, if Figures 1 to 5 As shown, the frame 10 is a machining device in the sandpaper production process, including a variety of drive and control components.

The winding part that has completed the winding begins to be unloaded and rotates toward the direction close to the transfer assembly 50. At the same time, the other set of winding parts, under the operation of the auxiliary roller changing assembly 30, covers the material on the winding part and continues to wind it, thereby reducing the reduction in work efficiency caused by winding and unloading. And the frame 10 controls and drives each moving component.

[0031] In this embodiment, if Figures 1 to 5 As shown, the rotating frame 201 is composed of two disks on both sides connected by a rotating central axis 202 in the middle. The rotating central axis 202 is mounted on the frame 10 and is driven by a transmission structure on the frame 10, which can be specifically a belt drive, to drive the rotating frame 201 to rotate as a whole, and to perform alternating work of the first rotating roller 204 and the second rotating roller 2010; an elastic clamping block 207 is arranged on the first mounting seat 206, and the compression and rebound of the elastic clamping block 207 are controlled by an electromagnetic valve to clamp the clamping groove 205, and the ends of the first rotating roller 204 and the second rotating roller 2010 are provided with driving servo motors, and the servo motors are connected to the control center of the frame 10.

Pneumatic sliders are used to drive the mounting frame 301 on both sides to slide back and forth relative to the frame 10 to approach or move away from the coil assembly 20, and the clamping part of the clamping roller 303 is made of flexible material to prevent damage to the material surface during the process of abutting the material. After the auxiliary turntable 304 receives the first rotating roller 204 or the second rotating roller 2010 into the accommodating groove 305, the frame 10 cooperates to drive and rotate the auxiliary turntable 304 to control the turning roller 306 eccentrically installed on the auxiliary turntable 304, so that the material reserved for slitting is closely attached to the surface of the first rotating roller 204 or the second rotating roller 2010 to cover the material on the roller body, thereby performing continuous winding, and then the frame 10 controls the mounting frame 301 to slide out of the working range of the coil assembly 20.

[0034] Furthermore, in some implementations of this embodiment, the auxiliary turntable 304 is provided with transmission teeth, and the mounting frame 301 is provided with driving teeth meshing with the transmission teeth to drive the auxiliary turntable to rotate around its own central axis.

[0036] Furthermore, in some implementations of this embodiment, the cutting assembly 40 includes: a lifting mechanism 401, a slide rail 402, and a slitting knife 403. The lifting mechanism 401 is mounted on the frame 10; the slide rail 402 is mounted on the lifting mechanism 401; and the slitting knife 403 is slidably mounted on the slide rail 402.

[0037] In this embodiment, if Figure 2 As shown, the lifting mechanism 401 can adopt a lifting cylinder, the slide rail 402 is a linear sliding guide rail, and the slitting knife 403 is installed on the slider. The lifting mechanism 401 and the slider are controlled by the frame 10, so that the slitting knife 403 rises after the first rotating roller 204 or the second rotating roller 2010 completes the rolling of the material, and then the material is automatically cut on the slide rail 402.

[0038] Further, in some implementations of this embodiment, Figure 3 As shown, the transfer assembly 50 includes: a sliding base 501, a telescopic platform 502, a driving member 503, a stopper 504, a baffle 505, a push rod 506, and a storage bin 507.

The block 504 is a block having two oppositely arranged inclined blocks, and the baffles 505 are arranged at both ends of the block 504 to prevent the material from jumping and sliding. The push rod 506 moves in a horizontal direction to push the material away from the block 504 to form a platform. The storage bin 507 can specifically be a bin for stacking or a stacking trolley for transportation.

[0040] In summary, in the process of using a back-pile sandpaper processing equipment, the automation degree of winding and unloading is improved by automatically controlling the auxiliary roller changing component 30, the winding component 20 and the transfer component 50, thereby improving the production efficiency; and by setting two winding sections, the materials are alternately wound and output, thereby reducing the reduction in work efficiency caused by winding and unloading.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention.
