[0044] Specifically, the hollow drill 21 has a drill head 210 and a shank 1201. The drill head 210 is used for drilling holes in the workpiece to be bound. The diameter of the shank 1201 is larger than the diameter of the drill head 210. The chip removal port 211 is arranged on the shank 1201. A protective cover 243 is provided on the outer cover of the shank 1201. The chip removal port 211 is connected to the inner cavity of the protective cover 243 to protect the hollow drill 21.

[0045] Specifically, the paper pressing mechanism 3 includes a paper pressing plate 12 movably arranged relative to the base frame 1, and a second driving component 19 for driving the paper pressing plate 12 to move back and forth to limit the workpiece to be bound on the base frame 1. The paper pressing mechanism 3 also includes an induction switch 336 arranged on the paper pressing plate 12 and used in conjunction with the second driving component 19. When the paper pressing plate 12 presses the workpiece to be bound on the base frame 1, the induction switch 336 touches the workpiece to be bound or the base frame 1 and cooperates with the second driving component 19 to stop running.

[0046] In this embodiment, a carrying plate 6 is provided in the middle of the base frame 1 for carrying the workpiece to be bound, and a wire groove 24 connected to the clearance hole 18 is provided on the carrying plate 6. A wire groove 24 connected to the clearance hole 18 is provided on the carrying plate 6. A release coil 26 and a slide plate assembly 5 for cooperating with the carrying plate 6 are provided on one side of the clearance hole 18.

[0047] Specifically, in a wire binding machine that is convenient for collecting paper scraps, the end of the oblique flow cover 113 in the paper scrap box 112 away from the chip discharge port 211 is lower than the end close to the chip discharge port 211. In this embodiment, the oblique flow cover 113 is at a 45° angle, and the end close to the chip discharge port 211 is parallel to the chip discharge port 211. The paper scraps generated by punching enter the bracket 221 through the chip discharge port 211 and enter the paper scrap box 112, where the oblique flow cover 113 flows to the end away from the chip discharge port 211 to collect the debris, and then enter the lower paper scrap box through the conduit. In this embodiment, since the hollow drill 21 is hollow inside, the paper scrap box 112 is arranged on one side of the top of the hollow drill 21. In actual production, the hollow drill 21 can be set to be solid, and the paper scrap box 112 can be set at the bottom of the hollow drill 21 to collect the fallen paper scraps.

[0048] Specifically, the hollow drill 21 is provided in a hollow cylindrical shape, and a chip discharge port 211 and a guide plate 212 located in the chip discharge port 211 are provided at one end of the hollow drill 21 away from the workpiece to be bound, and the guide plate 212 is extended from the outer wall of the hollow drill 21 in the direction of the hollow drill 21 close to the workpiece to be bound and is inclined toward the central axis of the hollow drill 21. The inclined design of the guide plate 212 makes it easier for the paper scraps in the hollow drill 21 to be guided to the guide bracket 221 during the gradual upward movement, and then to enter the upper paper scrap box 112 through the oblique flow cover 113, and then enter the lower paper scrap box 112 through the conduit to complete the paper scrap collection.

[0049] Specifically, in this embodiment, the conduit is a hose with a retractable length.

[0050] Specifically, in this embodiment, the collecting mechanism 29 includes a paper scrap box 112 disposed on the base frame 1 and connected to the chip discharge port 211, which is connected to the chip discharge port 211 and inclined toward the paper scrap box 112, and the chip discharge port 211 is connected to the paper scrap box 112 via the bracket 221. A protective cover 243 is provided on the outside of the handle 1201, and the inner cavity of the chip discharge port 211 connected to the protective cover 243 is connected to the protective cover 243 and is detachably connected. The closed structure prevents paper scraps from splashing in the process of entering the paper scrap box 112, and the setting of the protective cover 243 further prevents paper scraps from splashing on the basis of the handle 1201.

[0051] Specifically, the number of hollow drills 21 is multiple, and the number of hollow drills is equal to the number of driving members, and each driving member is used to control the rotation of the hollow drill 21 used in conjunction with it. Multiple hollow drills 21 can further improve the working efficiency of the wire binding machine and reduce labor costs, and the independent control of the rotation of a single hollow drill 21 allows the user to select the drilling position and number according to specific needs to a certain extent, which improves the flexibility of the binding process, and the independent control of a single hollow drill 21 can prevent the failure of a certain hollow drill 21 from affecting the overall working efficiency of the wire binding machine. In actual production, each hollow drill 21 can also be independently raised and lowered through structural design. The number of oblique flow covers 113 is two to avoid one oblique flow cover 113 from being blocked due to excessive waste. The two oblique flow covers 113 are respectively connected to the two ends of the bracket 221 that are far away from each other, which is more convenient for the circulation of paper scraps and prevents blockage.

[0052] Specifically, the second drive assembly 19 includes a sixth drive member 46, a second gear bar module 45 connected to the output shaft of the sixth drive member 46, and a second lifting plate 241 connected between the second gear bar module 45 and the paper pressing plate 12. The sixth drive member 46 drives the second lifting plate 241 via the second gear bar module 45 to link the paper pressing plate 12 to move up and down to press or release the work to be bound on the base frame 1. When completed, the seventh drive member 47 in the third drive assembly 30 cooperates with the fifth drive member 44 to enable the third gear bar module 245 to use the telescopic rod 25 to move the fixing assembly 242 closer to the hollow drill 21 so that the hollow drill 21 enters the protective cover 31 to avoid damage to the hollow drill 21 when idle, which is beneficial to extending the service life of the hollow drill 21.

[0053] Specifically, the paperboard 12 is provided with an avoidance hole for avoiding the hollow drill 21. The design of the avoidance hole can effectively increase the area of ​​the binding piece being limited at the drilling position required by the hollow drill 21, thereby improving the stability of the binding piece when being drilled.

[0054] Specifically, a side of the paper pressing plate 12 for pressing the pieces to be bound is provided with a frosted / anti-slip coating to further increase friction.

[0055] Specifically, in this embodiment, the paper pressing paper 12 is L-shaped.

[0056] The above contents are only preferred embodiments of the present invention.
