A through groove is formed in the top wall of the sliding groove, and the upper side of the through groove extends into the interior of the mounting plate. The lower surface of the moving plate extends into the sliding groove through the through groove formed in the top wall of the sliding groove. Springs are respectively fixedly connected to the opposite side surfaces of the two moving plates, and the opposite ends of the two springs are respectively fixedly connected to the two clamping blocks. The lower surfaces of the two clamping blocks are both inclined.

[0007] Preferably, a first fitting groove is formed in the upper surface of the needle plate, a second fitting groove is formed in the bottom wall of the first fitting groove, and clamping grooves adapted to the clamping blocks are respectively formed in the left and right inner walls of the second fitting groove.

The function of the accompanying drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0026] Please refer to Figure 1-7 , the present utility model provides a technical solution: a main shaft box type needle punching machine that is convenient for replacing the needle. It includes a support frame 1. An assembly plate 2 is arranged inside the support frame 1. An installation groove 3 is opened on the lower surface of the assembly plate 2. The top wall of the installation groove 3 is fixedly connected with an installation plate 4. The lower surface of the installation plate 4 is fixedly connected with an installation block 5. Slide grooves 6 are respectively opened on the left and right side surfaces of the installation block 5. Clamping blocks 7 are respectively slidably connected to the interiors of the two slide grooves 6. The left and right inner walls of the support frame 1 are respectively rotatably connected with threaded rods 8. The two threaded rods 8 are arranged in a mirror image. The closer ends of the two threaded rods 8 respectively rotatably penetrate into the interior of the installation block 5. The right end of the right threaded rod 8 rotatably penetrates out of the right side surface of the assembly plate 2. The closer ends of the two threaded rods 8 are fixedly connected with a bidirectional threaded rod 9. A needle plate 11 is arranged inside the installation groove 3. A locking assembly is arranged on the bidirectional threaded rod 9. When it is necessary to replace the needle, by rotating the right threaded rod 8, the two threaded rods 8 and the bidirectional threaded rod 9 will rotate synchronously. When the bidirectional threaded rod 9 rotates, it will synchronously cooperate with the locking assembly to drive the clamping blocks 7 to slide inside the slide grooves 6, thereby cooperating with subsequent components to unlock the needle plate 11. When fixing, just rotate the threaded rod 8 in the reverse direction to drive the bidirectional threaded rod 9 to rotate in the reverse direction, thereby completing the installation of the clamping blocks 7. Through the above structure, when replacing a large number of needles, the needle plate 11 can be removed more conveniently, so as to facilitate the disassembly of the needles in a special environment, avoiding the problems of narrow space during disassembly, repeated operations resulting in staff injuries and slow replacement progress.

[0027] Further, the locking assembly includes two moving plates 10, which are respectively threadedly sleeved on two opposite threaded portions of the bidirectional threaded rod 9. A through groove is formed in the top wall of the sliding groove 6, and the upper side of the through groove extends into the interior of the mounting plate 4. The lower surface of the moving plate 10 extends into the interior of the sliding groove 6 through the through groove. Springs 12 are respectively fixedly connected to the opposite side surfaces of the two moving plates 10, and the opposite ends of the two springs 12 are respectively fixedly connected to the two clamping blocks 7. The lower surfaces of the two clamping blocks 7 are both inclined. A first fitting groove 13 is formed in the upper surface of the needle plate 11, a second fitting groove 14 is formed in the bottom wall of the first fitting groove 13, and clamping grooves 15 adapted to the clamping blocks 7 are respectively formed in the left and right inner side walls of the second fitting groove 14. The first fitting groove 13 and the second fitting groove 14 are respectively adapted to the mounting plate 4 and the mounting block 5. Receiving grooves are formed in the left and right inner side walls of the mounting groove 3, and clamping plates 16 are respectively arranged in the two receiving grooves. The two clamping plates 16 are respectively threadedly sleeved on the outer surfaces of the two threaded rods 8. Grooves 17 adapted to the clamping plates 16 are respectively formed in the left and right side surfaces of the needle plate 11. A hook-shaped groove 18 is formed in the lower surface of the needle plate 11. A moving groove 19 is formed in the interior of the needle plate 11. A second threaded rod 20 is rotatably connected to the inner wall of the moving groove 19. The right end of the second threaded rod 20 rotatably penetrates through the right side surface of the needle plate 11. A pressing block 22 is threadedly sleeved on the outer surface of the second threaded rod 20. The pressing block 22 is slidably connected to the inner wall of the moving groove 19. The moving groove 19 communicates with the interior of the hook-shaped groove 18. A needle head 23 is arranged on the lower side of the needle plate 11. A fixing hook 21 is fixedly connected to the upper end of the needle head 23. During installation, the mounting plate 4 and the mounting block 5 are inserted into the interior of the first fitting groove 13 and the second fitting groove 14, so as to drive the two clamping blocks 7 into the interior of the clamping grooves 15 by means of the bidirectional threaded rod 9. At the same time, when the bidirectional threaded rod 8 rotates, the clamping plates 16 will be driven to move synchronously. After the clamping plates 16 move, they enter the interior of the grooves 17, so as to further fix the needle plate 11 by means of the clamping plates 16. When the needle head 23 needs to be disassembled, by rotating the second threaded rod 20, since the movement track of the pressing block 22 is restricted when the second threaded rod 20 rotates, the pressing block 22 will be driven to move synchronously when the second threaded rod 20 rotates. After the pressing block 22 moves horizontally and stops contacting the upper surface of the fixing hook 21, the fixing hook 21 can move freely. At this time, the needle head 23 to be replaced can be directly taken out. Through the above structure, it can be made more convenient to separately disassemble and install the needle head 23. Only one control component is needed to unlock all the needle heads 23, and the needle heads 23 will not automatically fall off by means of the fixing hook 21 after unlocking, effectively improving the efficiency during batch disassembly and installation.

[0028] Working principle: When it is necessary to replace the lancet, rotate the right threaded rod 8, so that the two threaded rods 8 and the bidirectional threaded rod 9 rotate synchronously. When the bidirectional threaded rod 9 rotates, it will cooperate with the locking component to drive the block 7 to slide inside the sliding groove 6, and then cooperate with the subsequent components to complete the unlocking of the needle plate 11. When fixing, just rotate the threaded rod 8 in the reverse direction to drive the bidirectional threaded rod 9 to rotate in the reverse direction, and then complete the installation of the block 7. When installing, insert the mounting plate 4 and the mounting block 5 into the first fitting groove 13 and the second fitting groove 14, so that the bidirectional threaded rod 9 drives the two blocks 7 into the clamping groove 15. At the same time, when the threaded rod 8 rotates, it will synchronously drive the clamping plate 16 to move. After the clamping plate 16 moves, it enters the groove 17, so as to further fix the needle plate 11 by using the clamping plate 16. When it is necessary to disassemble the needle tip 23, rotate the second threaded rod 20. When the second threaded rod 20 rotates, since the movement track of the pressing block 22 is restricted, the pressing block 22 will be driven to move synchronously when the second threaded rod 20 rotates. After the pressing block 22 moves horizontally, it stops contacting the upper surface of the fixing hook 21, so that the fixing hook 21 can move freely. At this time, just take out the needle tip 23 to be replaced.

[0029] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
