[0016] The working principle and beneficial effects of the present application are as follows: 1.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-9 As shown, this embodiment proposes a continuous punching device for processing file bags, including a frame 1. Both ends of the inner side of the frame 1 are rotatably connected to drive rollers 2. A conveyor belt 3 for placing file bags is arranged between the two drive rollers 2, and the two drive rollers 2 are connected by the conveyor belt 3. A drive mechanism 4 for intermittently rotating the drive rollers 2 is arranged on the outer side of the frame 1. A mounting frame 5 is fixedly connected to one end of the top of the frame 1. A punching mechanism 6 is arranged on the mounting frame 5. The punching mechanism 6 includes a first electric push rod 61 fixedly connected to the top of the mounting frame 5. A movable frame 62 is fixedly connected to the output end of the first electric push rod 61. The inner side of the movable frame 62... A slider 63 is slidably connected to the side and penetrates the bottom wall of the movable frame 62. A groove 65 is opened in the horizontal direction on the bottom wall of the movable frame 62. The slider 63 is clearance-fitted with the groove 65. A second electric push rod 64 is fixedly connected to one end of the inner side of the movable frame 62. The output end of the second electric push rod 64 is fixedly connected to the slider 63. A punching part 66 for punching holes in the file bag is provided at the bottom end of the slider 63. An operating table 7 is provided below the punching part 66. The operating table 7 is rotatably connected to the inner side of the frame 1 and is connected to the outlet end of the conveyor belt 3. A flipping mechanism 9 is provided on the outer side of the frame 1 to drive the operating table 7 to rotate by cooperating with the rotation of the transmission roller 2.

[0026] By placing file bags at equal intervals on the conveyor belt 3, and then starting the drive mechanism 4 to drive the transmission roller 2 to rotate intermittently, the conveyor belt 3 intermittently transports the file bags to the operating table 7. Then, the first electric push rod 61 is controlled to drive the movable frame 62 to move downward, so that the punching component 66 moves downward to contact the file bag and punch a hole in the file bag, thereby realizing the automatic transport and punching of the file bags. After punching is completed, the flipping mechanism 9 drives the operating table 7 to rotate and pour out the file bag. At the same time, the conveyor belt 3 transports the next file bag to the operating table 7 for punching, thus realizing the continuous automatic punching of different file bags without the need for frequent manual replacement of file bags, which greatly improves the punching efficiency of file bags. By controlling the second electric push rod 64 to drive the slider 63 to move along the slide groove 65, the movable frame 62 is moved, which can adjust the horizontal position of the punching part 66, thereby adjusting the punching position of the punching part 66 on the file bag, and thus meeting the requirements of different punching positions in actual needs.

[0027] Furthermore, the drilling component 66 includes a mounting plate 661 fixedly connected to the bottom of the slider 63. A drill bit 662 that slides with the relief groove 72 is fixedly connected to the bottom of the mounting plate 661. Sleeves 663 are fixedly connected to both ends of the bottom of the mounting plate 661. Sleeve rods 664 are slidably connected to the bottom ends of the two sleeves 663. Limit blocks 665 are fixedly connected to the bottom ends of the two sleeve rods 664. Springs 666 are sleeved on both sleeve rods 664. One end of the two springs 666 abuts against the corresponding sleeve 663, and the other end of the two springs 666 abuts against the corresponding limit block 665.

[0028] By controlling the first electric push rod 61 to drive the movable frame 62 downward, the mounting plate 661 drives the drill bit 662 downward, causing the drill bit 662 to come into contact with the file bag and drill a hole in the file bag. Before the drill bit 662 contacts the file bag, the limit block 665 will first come into contact with the operating table 7. The mounting plate 661 continues to move downward, causing the sleeve 663 and the sleeve rod 664 to slide relative to each other, which compresses the spring 666 and generates a reverse elastic force. This can slow down the moving speed of the mounting plate 661, thereby reducing the impact force of the drill bit 662 on the file bag and preventing the file bag from being damaged by the excessive impact speed of the drill bit 662.

[0029] Furthermore, a support plate 71 is fixedly connected to one end of the inner side of the frame 1, and one end of the bottom of the operating table 7 abuts against the support plate 71. A clearance groove 72 corresponding to the drilling component 66 is provided on the top of the operating table 7. The design of the clearance groove 72 allows the drill bit 662 to completely penetrate the file bag to make a hole, ensuring the integrity of the hole.

[0030] Furthermore, a file bag sensor is fixedly connected to the bottom of the mounting plate 661, a control box 10 is fixedly connected to the outside of the frame 1, a microcontroller connected to the file bag sensor signal is fixedly connected to the inside of the control box 10, and the first electric push rod 61 is electrically connected to the microcontroller.

[0031] The file bag sensor can detect file bags on the operating table 7. When there is a file bag on the operating table 7, the file bag sensor sends a signal to the microcontroller. Then, the microcontroller controls the first electric push rod 61 to drive the movable frame 62 to move downward, so that the mounting plate 661 drives the drill bit 662 to move downward, so that the drill bit 662 comes into contact with the file bag and punches a hole in the file bag. Then, the first electric push rod 61 drives the movable frame 62 to move upward to return to the initial position and wait for the next punching operation. In this way, continuous automatic punching of different file bags can be realized, effectively improving punching efficiency.

[0032] Furthermore, the drive mechanism 4 includes a rotating seat 41 coaxially fixedly connected to one of the transmission rollers 2. The outer edge of the rotating seat 41 is provided with a plurality of docking grooves 42 distributed at equal angles around the rotating seat 41. A motor 44 is fixedly connected to the outer side of the frame 1. The output shaft of the motor 44 is fixedly connected to a rotating wheel 45 tangent to the rotating seat 41. A connecting plate 46 is fixedly connected to one side of the rotating wheel 45. A drive block 47 is fixedly connected to one end of the connecting plate 46. The drive block 47 intermittently engages with any one of the docking grooves 42 by cooperating with the rotation of the connecting plate 46.

[0033] By starting the motor 44, the rotating wheel 45 is driven to rotate, causing the connecting plate 46 to drive the drive block 47 to rotate circumferentially. When the drive block 47 engages with one of the docking slots 42, the drive block 47 applies a rotational force to the rotating seat 41, causing the rotating seat 41 to rotate. When the drive block 47 disengages from the docking slot 42, the rotating seat 41 stops rotating. When the drive block 47 engages with the next docking slot 42, the rotating seat 41 rotates again until the drive block 47 disengages from the docking slot 42. This cycle repeats, allowing the rotating seat 41 to rotate intermittently, thus synchronizing the movement of the transmission roller 2. The conveyor belt 3 rotates intermittently, causing it to transport the file bags to the operating table 7 intermittently. During the intervals, the first electric push rod 61 drives the movable frame 62 to move downwards, causing the mounting plate 661 to drive the drill bit 662 downwards. This causes the drill bit 662 to come into contact with the file bag and punch a hole in it. After punching, the flipping mechanism 9 drives the operating table 7 to rotate and empty the file bag. At the same time, the conveyor belt 3 transports the next file bag to the operating table 7 for punching. This allows for automatic transport and continuous punching of file bags, eliminating the need for frequent manual replacement of file bags and reducing manual labor.

[0034] Furthermore, a guide plate 8 for exporting file bags is fixedly connected to one end of the inner side of the frame 1. The guide plate 8 is inclined, and its top end connects to one end of the operating table 7. The guide plate 8 is designed to export the file bags after punching for easy collection and organization.

[0035] Furthermore, the flipping mechanism 9 includes a gear 91 coaxially fixedly connected to the operating table 7. A torsion spring 92 is sleeved on the shaft of the gear 91. One end of the torsion spring 92 is welded to the outer wall of the frame 1, and the other end of the torsion spring 92 is welded to the gear 91. A linkage component is provided on the outer side of the frame 1, which drives the gear 91 to reciprocate intermittently by cooperating with the rotation of the transmission roller 2. The linkage component includes a mounting base 93 fixedly connected to the outer wall of the frame 1. A slide rod 94 passing through the mounting base 93 is slidably connected to one end of the mounting base 93. A toothed plate 95 is fixedly connected to one end of the slide rod 94, and the toothed plate 95 meshes with the gear 91. A pressure roller 96 is rotatably connected to the other end of the slide rod 94. A cam 97 is coaxially fixedly connected to one of the transmission rollers 2. The cam 97 intermittently abuts against the pressure roller 96 by cooperating with the rotation of the transmission roller 2.

[0036] Working principle: First, file folders are placed at equal intervals on conveyor belt 3. Then, motor 44 is started to drive wheel 45 to rotate, causing connecting plate 46 to drive drive block 47 to rotate circumferentially. When drive block 47 engages with one of the docking slots 42, drive block 47 applies rotational force to rotating seat 41, causing rotating seat 41 to rotate. When drive block 47 disengages from docking slot 42, rotating seat 41 stops rotating. When drive block 47 engages with the next docking slot 42, rotating seat 41 rotates again until drive block 45... 7 disengages from the docking groove 42, and repeats this cycle. The rotating seat 41 can rotate intermittently, causing the transmission roller 2 to rotate intermittently in sync, so that the conveyor belt 3 intermittently transports the file bag to the operating table 7. During the interval, the first electric push rod 61 drives the movable frame 62 to move downward, so that the mounting plate 661 drives the drill bit 662 to move downward, so that the drill bit 662 contacts the file bag and punches a hole in the file bag. Then the first electric push rod 61 drives the movable frame 62 to move upward and return to the initial position to wait for the next punching operation. When the drive roller 2 rotates again, the cam 97 rotates synchronously and abuts against the pressure roller 96, causing the pressure roller 96 to slide under the pressure of the cam 97. This causes the slide rod 94 to drive the toothed plate 95 to move, which in turn causes the gear 91 to rotate. At this time, the torsion spring 92 coils up and accumulates potential energy, causing the operating table 7 to flip and pour the punched file bag onto the guide plate 8. The punched file bag is then discharged and collected through the guide plate 8. When the pressure roller 96 disengages from the pressure roller 96, the torsion spring 92 releases potential energy, causing the operating table 7 to rotate in the opposite direction to the initial position. At the same time, the conveyor belt 3 transports the next file bag onto the operating table 7. This cycle can realize automatic replacement and unloading of file bags, eliminating the need for frequent machine stops for manual replacement of file bags and greatly improving the punching efficiency of file bags. When there is a file bag on the operating table 7, the file bag sensor sends a signal to the microcontroller. The microcontroller then controls the first electric push rod 61 to drive the movable frame 62 downward, causing the mounting plate 661 to drive the drill bit 662 downward, so that the drill bit 662 comes into contact with the file bag and punches a hole in the file bag. Then the first electric push rod 61 drives the movable frame 62 upward to return to the initial position to wait for the next punching operation. This can realize continuous automatic punching of different file bags, further improving punching efficiency.
