[0024] This specific embodiment is a voice coil reinforcing paper cutting device, the structural schematic diagram of which is shown below. Figures 1-6 As shown, the machine includes a frame 1. A mounting plate 102 is fixedly installed on the left side of the frame 1 via a connecting column 101. A top plate 103 is bolted to the top of the rear end of the frame 1. A cutting mechanism is installed inside the rear end of the frame 1. A length-fixing mechanism for ensuring consistent cutting length is installed inside the frame 1 and in front of the cutting mechanism. An adjustment mechanism is installed at the upper inside of the frame 1 and in front of the length-fixing mechanism.
[0025] In practice, one end of the reinforcing paper is sequentially passed through an adjustment mechanism and a length-fixing mechanism. The adjustment mechanism can be adjusted according to the width of the reinforcing paper and guide its movement to prevent displacement and inaccurate cutting. The length-fixing mechanism can both transport the reinforcing paper and set the time span between its operation and pause according to the designed length of the reinforcing paper, i.e., the distance the reinforcing paper moves within a set time. This not only improves cutting efficiency but also ensures the consistency of the length of the cut reinforcing paper and reduces the defect rate.
[0026] The adjustment mechanism includes a support plate 5, which is bolted to the top of the frame 1. The support plate 5 has two symmetrically arranged rectangular holes 501 along its length in the middle. Two U-shaped blocks 6 are slidably connected between the tops of the two rectangular holes 501. A stop plate is bolted to the open end of the bottom of the U-shaped block 6, and the stop plate is in contact with the lower surface of the support plate 5. The rear end of the U-shaped block 6 is integrally formed with an inclined block, and the lower surface of the inclined block is in contact with the upper surface of the support plate 5. In this way, when dealing with reinforcing paper of different widths, it is only necessary to loosen the bolt at the bottom to disengage the stop plate from the U-shaped block 6, so that the distance between the two U-shaped blocks 6 can be adjusted. Finally, by tightening the bolt, the two U-shaped blocks 6 can guide the reinforcing paper.
[0027] In addition, the adjustment mechanism also includes two L-shaped plates 7, which are respectively bolted to the upper ends of the front sides of the frame 1. Three round rods 701 are fixedly installed between the two L-shaped plates 7. The left projection of the three round rods 701 is triangular. Two adjustment plates 8 are slidably connected to the three round rods 701, and the two adjustment plates 8 are opposite to the two U-shaped blocks 6. The distance between the two adjustment plates 8 is equal to the distance between the two U-shaped blocks 6. The lower end of the front of the adjustment plate 8 is provided with an adjustable bolt. By adjusting the distance between the two adjustment plates 8 and cooperating with the two U-shaped blocks 6, the reinforcing paper can be guided.
[0028] In addition, the two upper round rods 701 are located above the support plate 5, and the top of the lower round rod 701 is flush with the upper surface of the support plate 5; while the two adjusting plates 8 guide the reinforcing paper, the lower round rod 701 and the two upper round rods 701 can smooth the reinforcing paper.
[0029] In addition, the length-fixing mechanism includes a drive motor 2 bolted to the left side of the mounting plate 102 and a drive roller 201 located inside the frame 1. Both ends of the drive roller 201 are rotatably connected to the inner wall of the frame 1 via bearings. The output end of the drive motor 2 passes through the mounting plate 102 and is connected to one end of the drive roller 201 via a coupling. Support plates 104 are fixedly installed on both sides of the rear end of the frame 1. A rotating rod 202 is installed between the rear ends of the two support plates 104 at a position corresponding to the drive roller 201. A driven roller 203 is sleeved in the middle of the rotating rod 202 via a bearing. The inside of the frame 1 and located between the drive roller 201 and the driven roller 203 are connected to the drive roller 201. Furthermore, a transition plate 4 is bolted between each mechanism, and the upper surface of the transition plate 4 is flush with the top of the active roller 201. The drive motor 2 drives the active roller 201 to rotate counterclockwise through the coupling. The active roller 201 drives the driven roller 203 to rotate clockwise through the reinforcing paper, so that the reinforcing paper can be stably output to the rear cutting mechanism. By setting the running time of the drive motor 2, the active roller 201 can intermittently convey the reinforcing paper. That is, the length of the reinforcing paper conveyed is calculated by the number of rotations of the active roller 201. When the set number of rotations is reached, the drive motor 2 stops rotating, and the cutting mechanism runs to cut the reinforcing paper.
[0030] In addition, the cutting mechanism includes a cylinder 3 bolted to the middle of the top of the top plate 103. The output end of the cylinder 3 passes through the top plate 103 and extends downward to be fixedly connected to a connector 301. The lower end of the connector 301 has a convex cross-section. An L-shaped block 302 is installed on the outer side of the lower end of the connector 301. The top center of the L-shaped block 302 is provided with a mounting hole that matches the lower end of the connector 301. A lifting plate 303 is bolted to the inner side of the L-shaped block 302. A U-shaped plate 305 is provided on the front side of the lifting plate 303 and bolted to the frame 1. A cutting blade 307 is bolted to the center of the front of the lifting plate 303. The cylinder 3 outputs downward and drives the L-shaped block 302 downward through the connector 301, so that the L-shaped block can drive the lifting plate 303 and the cutting blade 307 downward. The cutting blade 307 can cut the reinforcing paper that is not moving, thereby ensuring the consistency of the length of the reinforcing paper after cutting.
[0031] In addition, mounting slots 105 are provided at both ends of the rear side of the frame 1. Both ends of the lifting plate 303 and the U-shaped plate 305 are located inside the mounting slots 105. Slider 306 is provided at the rear side of both ends of the U-shaped plate 305. Slide grooves 304 are provided at the front side of both ends of the lifting plate 303. The slider 306 is slidably connected to the inside of the slide groove 304. Side plates 313 are slidably connected at the rear side of both ends of the lifting plate 303. The side plates 313 are bolted to the inner wall of the frame 1. When the lifting plate 303 moves up and down, the slide grooves 304 on its rear side and its front side slide with the side plates 313 and the slider 306 respectively to ensure the stability of the movement of the lifting plate 303.
[0032] In addition, the top of the lifting plate 303 and both sides of the L-shaped block 302 are provided with grooves. Mounting blocks 308 are bolted into the interior of each groove. The front end of the mounting block 308 extends forward to above the U-shaped plate 305. A guide rod 309 is slidably connected to the middle of the extended end of the mounting block 308. A pressure plate 311 is fixedly connected to the end of the guide rod 309 away from the mounting block 308. A spring 310 is sleeved on the outside of the guide rod 309, and both ends of the spring 310 are fixedly connected to the mounting block 308 and the pressure plate 311, respectively. A rubber pad 312 is fixedly connected to the side of the pressure plate 311 away from the guide rod 309. To prevent the reinforcing paper from shifting during the cutting process of the cutting blade 307, the... The downward movement of the lifting plate 303 drives the mounting block 308 downward. The mounting block 308 drives the guide rod 309, spring 310, and pressure plate 311 downward. When the rubber pad 312 under the pressure plate 311 presses against the reinforcing paper, it continues to press down, causing the mounting block 308 to squeeze the spring 310, which in turn squeezes the pressure plate 311. This causes the pressure plate 311 to press the reinforcing paper tightly through the rubber pad 312. At the same time, the upper end of the guide rod 309 can slide within the mounting block 308. While the rubber pad 312 is pressing the reinforcing paper, the cutting blade 307 cuts the reinforcing paper, which not only prevents the reinforcing paper from shifting during cutting but also ensures the accuracy of the cutting and the consistency of the reinforcing paper length.
[0033] All technical features in this embodiment can be freely combined according to actual needs.
[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
