Technical Field

[0001] This utility model relates to the field of sound-absorbing cotton production technology, and in particular to a slitting device for sound-absorbing cotton production. Background Technology

[0002] Sound-absorbing cotton is a type of man-made inorganic fiber. It is generally made from natural minerals such as quartz sand, limestone, and dolomite as the main raw materials, combined with some chemical raw materials such as soda ash and borax to melt into glass. In the molten state, it is blown into flocculent fine fibers by external force. The fibers are three-dimensionally intertwined and entangled with each other, presenting many tiny gaps. It is mainly used as a material for sound insulation and heat insulation.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 The present invention will be described in further detail below.

[0025] This utility model discloses a slitting device for producing sound-absorbing cotton. (Refer to...) Figures 1-6 The system includes a base plate 1, a main plate 2 fixedly connected to the top of the base plate 1, a cutting mechanism 3 on the main plate 2, a mounting roller 31, the mounting roller 31 being disposed inside the main plate 2, a first lifting block 32 slidably connected to one side wall of the main plate 2, a second lifting block 33 slidably connected to the other side wall of the main plate 2, the two ends of the mounting roller 31 being rotatably connected to the first lifting block 32 and the second lifting block 33 respectively, a placement seat 34 being disposed inside the mounting roller 31, the placement seat 34 extending out of the mounting roller 31, a cutter 35 being disposed on the outside of the mounting roller 31, and a mounting plate 36 being fixedly connected to the cutter 35. The mounting plate 36 is placed inside the placement seat 34 and matches the placement seat 34. The mounting roller 31 has a horizontal plate 37 inside, and a first cylinder 38 is fixedly connected to the bottom of the horizontal plate 37. A rectangular plate 39 is fixedly connected to the inner wall of the mounting roller 31, and a spring 391 is fixedly connected to the rectangular plate 39. One end of the spring 391 is fixedly connected to the placement seat 34. The sound-absorbing cotton to be cut is placed on the top of the base plate 1. According to the set requirements, the mounting roller 31 is controlled to rotate to select the matching cutter 35 facing directly downward. After selection, the first cylinder 38 is controlled to extend to push the cutter 35 outward from the mounting roller 31 for use. This operation can quickly switch between different cutters 35, and the whole process does not require much manual intervention, which saves manpower. It can adapt to the cutting requirements of different shapes and improves the cutting efficiency.

[0026] The placement seats 34 are evenly spaced around the inside of the mounting roller 31. The two ends of the horizontal plate 37 are fixedly connected to the first lifting block 32 and the second lifting block 33, respectively. One end of the first cylinder 38 is fixedly connected to a touch plate 392, which contacts the placement seat 34. A motor 393 is fixedly connected to one side of the first lifting block 32. The motor 393 is fixedly connected to a first gear 394 through an output shaft. A second gear 395 is fixedly connected to the outside of the mounting roller 31. After the motor 393 works, it drives the first gear 394 to rotate.

[0027] The second gear 395 is located behind the first gear 394 and meshes with the first gear 394. When the first gear 394 rotates, it drives the second gear 395 to rotate. A U-shaped plate 396 is provided on the top of the main body plate 2. The U-shaped plate 396 penetrates the top wall of the main body plate 2. Both ends of the U-shaped plate 396 are fixedly connected to the top of the first lifting block 32 and the second lifting block 33, respectively. A second cylinder 397 is fixedly connected to the top wall of the U-shaped plate 396. One end of the second cylinder 397 is fixedly connected to the top of the main body plate 2. After the second cylinder 397 works, it pushes and pulls the U-shaped plate 396 up and down.

[0028] Positioning plates 398 are fixedly connected to both ends of the placement base 34. The positioning plates 398 extend out of the outside of the mounting roller 31. A locking block 399 is slidably connected to the inside of the positioning plates 398. The locking block 399 extends into the inside of the placement base 34. The mounting plate 36 has a locking groove 381 at both ends. The locking block 399 extends into the locking groove 381 and matches the locking groove 381. A threaded rod 382 is rotatably connected to one side of the locking block 399. The threaded rod 382 extends out of the outside of the positioning plate 398 and is threadedly connected to the positioning plate 398. After the threaded rod 382 rotates, it drives the locking block 399 to move.

[0029] A positioning component 4 is fixedly connected to the top of the base plate 1. The positioning component 4 includes two support plates 41 and two fixing plates 42. The two support plates 41 are respectively set on the front and rear sides of the mounting roller 31. The support plates 41 are fixedly connected to the top of the base plate 1 and penetrate through the top wall of the fixing plate 42. A third cylinder 43 is fixedly connected to the top of the inner side of the support plate 41. One end of the third cylinder 43 is fixedly connected to the top of the fixing plate 42. After the third cylinder 43 works, it pushes and pulls the fixing plate 42 up and down.

[0030] In actual operation, first connect the power supply to the device. Different cutter bodies can be selected and installed on different placement seats 34 for flexible switching during subsequent processing. Specifically, during installation, insert the mounting plate 36 on the selected cutter body into the corresponding placement seat 34. After insertion, rotate the threaded rod 382. The threaded rod 382 drives the locking block 399 to move, causing the locking block 399 to enter the slot 381 of the mounting plate 36. Then the mounting plate 36 can be fixed, and the installation and fixing of the cutter body is completed. The corresponding cutter body loading and unloading process is simple and convenient, which is conducive to users quickly getting started with the operation. During the specific cutting process, after the sound-absorbing cotton to be cut is placed on the top of the base plate 1, the third cylinder 43 pushes the fixing plate 42 after it is activated, causing the fixing plate 42 to move downward and press the sound-absorbing cotton in place, thereby maintaining the stability of the sound-absorbing cotton during cutting. After the sound-absorbing cotton is fixed, the motor 393 drives the first gear 394 to rotate, the first gear 394 drives the second gear 395 to rotate, and the second gear 395 drives the mounting roller 31 to rotate. Through the above connection relationship, it can be seen that during the rotation of the mounting roller 31, different blades can be switched to vertically downward. When the corresponding blade is facing directly downward, the first... After the cylinder 38 extends, it pushes the touch plate 392, causing the touch plate 392 to touch the placement seat 34. As the first cylinder 38 continues to extend, the placement seat 34 is pushed outward of the mounting roller 31. Correspondingly, the selected blade is also pushed out, thus completing the selection of the blade. During this process, the spring 391 maintains the tension on the placement seat 34. When the first cylinder 38 retracts, the spring 391 pulls the placement seat 34 back into the mounting roller 31, thus completing a certain degree of blade storage function and preventing the blade from extending too far outside the mounting roller 31 and interfering with the subsequent slitting work. After the second cylinder 397 is working, it pushes the U-shaped plate 396. The U-shaped plate 396 drives the first lifting block 32 and the second lifting block 33 to move synchronously. The first lifting block 32 and the second lifting block 33 drive the installation roller 31 to move up and down. According to the above connection relationship, when the installation roller 31 descends, the cutting operation of the knife body on the sound-absorbing cotton is completed.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
