Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0025] Combination Figure 1 This utility model discloses a rotary multi-station keyhole punching device for processing handbags, including a base 1 that supports and houses all the components of the device. A feeding base 2 is fixedly connected to the top center of the base 1, supporting and installing the components of the feeding mechanism. A rotating motor 3 is fixedly connected through and to the front side of the bottom of the feeding base 2, providing power to the feeding pulley group 5 and controlling the transmission direction of the feeding pulley group 5. A transmission pulley group 4 is provided at the output end of the rotating motor 3, transmitting the power of the rotating motor 3 to the feeding pulley group 5. A feeding platform 7 is provided on the top of the feeding base 2, carrying and transporting handbags 12 and clamping and flipping mechanisms. The handbags 12, the objects to be processed, are located on the top of the feeding platform 7. A column 15 is fixedly connected to the rear side of the top of the base 1, supporting the punching mechanism.
[0026] Combination Figure 2 and Figure 3 The driven pulley of the transmission pulley group 4 is fixedly connected to the feeding pulley group 5 via a connector, the transport feeding table 7 and its clamping and flipping device, and the feeding pulley group 5 is fixedly connected to the feeding base 2. The rear side of the rotating motor 3 is provided with a power supply 6 to provide power to the rotating motor 3. The top of the feeding table 7 is provided with a folding bracket 8 to support the handbag 12. The front side of the feeding table is fixedly connected with a rotating cylinder 9 to drive the clamping mechanism and the handbag 12 to flip. The rotating part of the rotating cylinder 9 is fixedly connected with a pneumatic gripper 10 via a connector to clamp the handbag 12. The bottom rear position of the feeding base 2 is provided with an induction switch 13. When the feeding table 7 is detected, the rear blocking cylinder 14 is activated, and the induction switch 13 is fixedly connected to the base 1 via a connector. The rear position of the feeding base 2 is provided with a blocking cylinder 14, which is activated to block the feeding table 7 from continuing to move forward and divide the work station. The cylinder body of the blocking cylinder 14 is fixedly connected to the base 1 via a connector.
[0027] Combination Figure 4A Y-axis push cylinder 17 is fixedly connected to the bottom of the mounting plate 16, which drives the punching mechanism to move in the Y direction to a suitable position. The cylinder body of a Z-axis push cylinder 18 is fixedly connected to the bottom of the output end of the Y-axis push cylinder 17, which drives the punching mechanism to move in the Z direction to perform downward punching. A punch turntable 19 is fixedly connected to the bottom of the output end of the Z-axis push cylinder 18, which is equipped with various sizes of keyhole punches 20. The outer part of the punch turntable 19 is fixedly connected with evenly distributed keyhole punches 20. After moving to a suitable position with the punching mechanism, they contact the handbag 12 and press down to perform punching.
[0028] Working principle: At the start of work, the worker installs the handbag 12 to be processed on the support plate 11, then activates the pneumatic gripper 10 to hold the handbag 12 in place. The handbag 12 is then clamped onto the feeding table 7, which is the loading station. The power supply 6 is then activated to drive the rotary motor 3. The power of the drive motor 3 is transmitted to the feeding pulley group 5 via the conveyor belt pulley group 4, thus moving the feeding table 7, the handbag 12, and the clamping mechanism. When the feeding table 7 reaches the induction switch 13, the induction switch 13 senses and activates the blocking cylinder 14, causing the blocking cylinder 14 to rise. The feeder 7 is stopped from moving further, thus defining the punching station. Then, the Y-axis push cylinder 17 moves the punching mechanism to the position where punching is needed. The Z-axis push cylinder 18 is activated, which pushes down the keyhole punch 20 to punch. Then, the rotary cylinder 9 rotates, which drives the pneumatic gripper 10 to flip the handbag 12. After that, the Z-axis push cylinder 18 pushes down again to complete the keyhole punching on the reverse side of the handbag 12. If the size of the keyhole punch 20 needs to be changed, the operator can rotate the punch turntable 19 to switch to a keyhole punch 20 of a different size. In this way, the keyhole punching work of the handbag 12 is completed.
