DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The present application embodiment discloses a leather six-diameter needle punching device. Figure 1-3 A six-aperture punching device for leather comprises a frame 1, a cylinder 3 is fixedly mounted on the top outer wall of the frame 1, an output end of the cylinder 3 passes through the frame 1 downward and is fixedly connected to a fixing plate 4, a mounting plate 5 is fixedly connected to the bottom outer wall of the fixing plate 4, a plurality of punching needles 6 with different apertures are mounted below the mounting plate 5, and an adjustment mechanism is mounted on the outer walls of the fixing plate 4 and the mounting plate 5 for adjusting the punching needle 6 with a suitable aperture for punching;

[0019] The adjusting mechanism includes a worm gear 7 rotatably connected to the bottom outer wall of the fixed plate 4 and a plurality of slide rods 12 slidably connected to the outer wall of the mounting plate 5. The bottom outer wall of the worm gear 7 is fixedly connected with a right-angled trapezoidal block 11, and the top ends of the plurality of slide rods 12 are fixedly connected with round balls 13. The right-angled trapezoidal block 11 is in contact with the plurality of round balls 13. A spring 14 is installed on the outer wall of the slide rod 12, and the spring 14 is located between the round balls 13 and the mounting plate 5. The bottom ends of the plurality of slide rods 12 are fixedly connected with a limiting plate 15, and the punch 6 is fixedly installed on the bottom outer wall of the limiting plate 15.

[0020] The adjustment mechanism also includes a worm 9 rotatably connected to the bottom outer wall of the fixed plate 4 through two shaft seats 8, the worm 9 is meshed with the worm wheel 7, and a servo motor 10 is fixedly installed on the bottom outer wall of the fixed plate 4, and the end of the output shaft of the servo motor 10 is fixedly connected to one end of the worm 9.

[0021] The bottom outer wall of the frame 1 is embedded with a base 2 , and the outer wall of the base 2 is provided with a plurality of through-type punching holes 16 , and the plurality of punching holes 16 correspond to and fit with the plurality of punching needles 6 .

[0022] A plurality of slide bars 12 are evenly distributed on the outer wall of the mounting plate 5 in a circular array with equal spacing.

[0023] The implementation principle of the six-aperture punching device for leather in the embodiment of the present application is as follows: when in use, the leather is laid on the base 2, and then the servo motor 10 is started through the adjustment mechanism, and the output shaft of the servo motor 10 drives the worm 9 to rotate. When the worm 9 rotates, it drives the worm wheel 7 meshing with it to rotate, and then drives the right-angled trapezoidal block 11 to rotate around the axis of the worm wheel 7 through the worm wheel 7. When the right-angled trapezoidal block 11 rotates, its inclined surface will abut against a round ball 13. When the right-angled trapezoidal block 11 continues to rotate, a round ball 13 will be squeezed downward through the inclined surface, and the round ball 13 will drive the slide bar 12 to slide down. At this time, the slide bar 12 drives the punch 6 to move downward until one punch 6 is lower than the bottom ends of the other punches 6, and the servo motor 10 is turned off to stop the worm 9 from rotating. Since the meshing of the worm 9 and the worm wheel 7 is self-locking, the right-angled trapezoidal block 11 can be locked, and the height of the bottom end of one punch 6 is fixed. Then the cylinder 3 is started, and the output end of the cylinder 3 is extended to drive the fixed plate 4 to press down, thereby driving the multiple punches 6 to press down. The punch 6 protruding downward will contact the leather before the other punches 6, and then cooperate with the punching hole 16 on the base 2 to punch the leather.

[0024] When it is necessary to switch the punching needles 6 with different apertures for punching, the servo motor 10 can be started again, and the worm gear 7 can be driven to rotate in the same way. When the right-angled trapezoidal block 11 continues to rotate, its inclined surface will separate from a ball 13 in contact with it. Since the ball 13 will cooperate with the mounting plate 5 to squeeze the spring 14 during the downward pressing process, the spring 14 will generate elastic force. When the inclined surface of the right-angled trapezoidal block 11 separates from the contact with the ball 13, the ball 13 is no longer subjected to the squeezing force, and it is reset under the elastic force of the spring 14. A punching needle 6 for punching is reset through the sliding rod 12, and when the right-angled trapezoidal block 11 continues to rotate around the axis of the worm gear 7, the next round ball 13 is squeezed, and the next punching needle 6 with a different aperture is squeezed downward so that it protrudes from the bottom ends of the other multiple punching needles 6, thereby completing the switching operation. Compared with the prior art, the equipment has multiple punching needles 6 with different apertures, which can be used for multiple purposes to meet the punching needs of different apertures. There is no need for frequent disassembly and assembly when replacing the punching needle 6, thereby improving the processing efficiency.
