[0002] When sorting bills, documents, account books, etc., a binding machine is required for binding operations. Commonly used binding machines usually press and fix the bills first, then punch holes on the sides, insert rivet tubes, and then press and fix the two ends of the rivet tubes by heating the rivet tubes to achieve the binding of the documents. However, in the prior art, the pressing and fixing operation of the bills is usually continuous, and the paper pressing mechanism does not stop working until the punching is completed. This method may cause creases, bends or tears on the tickets, affecting their appearance and readability; and the paper pressing board is also easily damaged after being subjected to a large pressing force. In addition, the paper scrap collection device for the binding machine in the prior art is not reasonably designed in structure, has a small capacity, needs to be dumped multiple times, and is more likely to cause paper scraps to splash, all of which will lead to poor binding effects of the binding machine.

DETAILED DESCRIPTION

[0034] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0035] See also Figures 1 to 13 As shown, the utility model is a structurally improved multi-hole wire binding machine, comprising a workbench 1 for carrying external binding pieces, a punching mechanism 2 movably mounted on the workbench 1; and a paper pressing mechanism 3 arranged in cooperation with the punching mechanism 2. The punching mechanism 2 comprises a drill 21 movably arranged on the workbench 1, and a first driving assembly 22 for driving the drill 21 to reciprocate to punch holes in the binding pieces.

[0036] The paper pressing mechanism 3 includes a paper pressing plate 31 movably arranged relative to the workbench 1, and a second driving component 32 for driving the paper pressing plate 31 to move back and forth to limit the workpiece to be bound on the workbench 1. The paper pressing mechanism 3 also includes a sensing switch 33 arranged on the paper pressing plate 31 and used in conjunction with the second driving component 32. The sensing switch 33 is provided with a sensing sheet 331 protruding from the paper pressing plate 31. When the paper pressing plate 31 presses the workpiece to be bound on the workbench 1, the sensing sheet 331 touches the workpiece to be bound or the workbench 1 and cooperates with the second driving component 32 to stop running.

[0037] In this embodiment, the workbench 1 is roughly "L"-shaped, with a carrier plate 12 in the middle of the workbench 1 for carrying the pieces to be bound, a punching mechanism 2 arranged above the pieces to be bound, and a paper pressing mechanism 3 located on one side of the carrier plate 12; there are three drills 21, three drills 21 arranged in parallel, and each drill 21 is equipped with a rotating motor to drive its rotation, and the three motors (first motor 221) are connected to a lifting motor (second motor 222) through a gear rack set. The collecting assembly 23 is arranged on one side of the drill 21 for collecting paper scraps generated by the drill 21, and an avoidance groove is provided on the paper pressing paper 31 to facilitate the drill 21 to perform punching.

[0038] Specifically, an arcuate portion 3311 is provided at one end of the sensing sheet 331 away from the sensing switch 33, and the arcuate portion 3311 is used to contact the workpiece to be bound on the workbench 1, and an avoidance hole 34 is provided on the paper pressing plate 31; when the paper pressing plate 31 does not press the workpiece to be bound, the arcuate portion 3311 protrudes out of the avoidance hole 34, and the sensing switch 33 is in a normally closed state, so that the second drive component 32 is powered on; when the paper pressing plate 31 presses the workpiece to be bound, the arcuate portion 3311 is completely located in the avoidance hole 34, and the sensing switch 33 is in a normally open state, so that the second drive component 32 is powered off and brakes the paper pressing plate 31.

[0039] In this embodiment, a central controller (not shown in the figure) is provided on the workbench, and the sensing switch 33 is connected to the second driving component through the central controller. In actual use, when the paper pressing plate 31 presses the workpiece to be bound on the workbench 1, the sensing sheet 331 contacts the sensing switch 33 under the reaction force of the workpiece to be bound, and the sensing switch 33 receives the pressing signal and transmits it to the central controller. Thereafter, the central controller controls the second driving component 32 to stop working to brake the paper pressing plate 31.

[0040] Specifically, the structure-improved multi-hole wire-binding machine further includes a collection assembly 23 for collecting paper scraps generated by drilling holes with the drill 21. The collection assembly 23 includes a paper scrap box 231 that is pulled out and set on the workbench 1. The paper scrap box 231 is located on one side of the top of the drill 21 or at the bottom of the drill 21. In this embodiment, since the drill 21 is hollow inside, the paper scrap box 231 is set on one side of the top of the drill 21. In actual production, the drill 21 can be set to a solid shape, and the paper scrap box 231 is set at the bottom of the drill 21 to collect the fallen paper scraps.

[0041] Specifically, the drill 21 is in the form of a hollow cylinder, 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 drill 21 away from the workpiece to be bound. The guide plate 212 extends from the outer wall of the drill 21 toward the direction of the drill 21 approaching the workpiece to be bound and is inclined toward the central axis of the drill 21. The inclined design of the guide plate 212 makes it easier for the paper scraps in the drill 21 to be guided to the guide pipe 233 during the gradual upward movement.

[0042] Specifically, in this embodiment, the collecting assembly 23 includes a paper scrap box 231 disposed on the workbench 1 and connected to the chip discharge port 211, and a guide pipe 233 connected to the chip discharge port 211 and inclined toward the paper scrap box 231, and the chip discharge port 211 is connected to the paper scrap box 231 via the guide pipe 233. A protective cover 24 is provided on the outside of the handle 2101, the chip discharge port 211 is connected to the inner cavity of the protective cover 24, and the guide pipe 233 is connected to the protective cover 24 and is detachably connected. The closed structure of the guide pipe 233 prevents paper scraps from splashing in the process of entering the paper scrap box 231, and the setting of the protective cover 24 further prevents paper scraps from splashing on the basis of the handle 2101.

[0043] In this embodiment, an observation window 242 and a connection hole 241 for connecting to the material guide pipe 233 are provided above the protective cover 24. The observation window 242 can be used to observe the amount of paper scraps in the protective cover 24, which is convenient for the operator to perform maintenance and cleaning.

[0044] Specifically, the end of the guide tube 233 close to the scrap box 231 is provided with a scrap chute 232, the workbench 1 is provided with a first connecting member 11, and the end of the scrap chute 232 away from the scrap box 231 is rotatably arranged on the first connecting member 11. In actual use, one end of the scrap chute 232 can be rotatably arranged on the guide tube 233; or the scrap chute 232 can be omitted, and the guide tube 233 can be directly used to connect the scrap box 231. However, considering that it will be difficult to clean if the guide tube 233 is used in its entirety, the length of the guide tube 233 is shortened and the scrap chute 232 is installed at its end, so as to further reduce the occurrence of clogging and enable real-time observation of the scrap discharge state.

[0045] The paper scrap chute 232 in this embodiment is an integrated structure, and three slides 2321 are set on the paper scrap chute 232 corresponding to the number of chip discharge ports 211. The design of the three slides 2321 allows the paper scraps to be diverted during the process of being discharged into the paper scrap box 231. Compared with the design of one slide 2321, this structure avoids overflow caused by excessive accumulation of paper scraps in a certain place in the paper scrap box 231 during long-term operations, which can effectively reduce cleaning costs.

[0046] The setting of the shavings chute 232 rotating also provides the chute with an angle adjustment within a certain range. When too much shavings are accumulated at a certain place in the shavings box 231, the operator can manually adjust the angle of the shavings chute 232 to prevent the shavings from overflowing. In actual use, a sensor that can detect the height of the shavings accumulation can be set in the shavings chute 232, and the shavings chute 232 is driven by an electric control device. When the sensor detects that the accumulation height is too high, it transmits a signal to the electric control device, and the electric control device drives the shavings chute 232 to automatically adjust the tilt angle to adapt to the long-term working environment.

[0047] Specifically, the drill 21 has a drill head 210 and a shank 2101. The drill head 210 is used for drilling holes in the workpiece to be bound. The diameter of the shank 2101 is larger than the diameter of the drill head 210. The chip removal port 211 is arranged on the shank 2101. The shank 2101 is provided with a protective cover 24 on the outer sleeve and is rotatably connected to the protective cover 24 through a bearing 243. The chip removal port 211 is connected to the inner cavity of the protective cover 24, and the material guide tube 233 is connected to the chip removal port 211 via the connecting hole 241 on the protective cover 24. In this embodiment, the material guide tube 233 is a two-petal structure. In actual use, if maintenance and cleaning are required, the material guide tube 233 can be disassembled; the chip discharge port 211 penetrates the shank portion 2101 along the radial direction of the shank portion 2101, and the guide plate 212 is arranged at one end of the shank portion 2101 away from the drill bit 21. The arrangement of the shank portion 2101 expands the capacity of the drill bit 21 to accommodate paper scraps to a certain extent, thereby preventing the drill bit 21 from being blocked when working for a long time.

[0048] Specifically, the workbench 1 is provided with a drawer shell 234 covering the scrap box 231, and the drawer shell 234 is provided with a feed port 2341 connecting the scrap chute 232 and the scrap box 231, and the scrap box 231 is slidably installed in the drawer shell 234. In this embodiment, the scrap box 231 is in a rectangular parallelepiped shape, and the three slideways 2321 on the scrap chute 232 pass into the interior of the scrap box 231 through the feed port 2341; the sliding installation of the scrap box 231 makes it detachable from the binding machine, which is convenient for the operator to pull out the scrap box 231 for cleaning and replacement. This design simplifies the maintenance and cleaning process and saves the operator's time and energy.

[0049] Specifically, the first driving assembly 22 includes a first motor 221, the output shaft of which is connected to one end of the drill 21 and is used to drive the drill 21 to rotate; the first driving assembly 22 also includes a second motor 222, a first gear rack module 223 connected to the second motor 222, and a first lifting plate 224 connected between the first gear rack module 223 and the first driving assembly 22, and the second motor 222 drives the first driving assembly 22 to move up and down in conjunction with the drill 21 via the first gear rack module 223. In this embodiment, a sliding hole 2241 is provided on the first lifting plate 224, and a limiting rod 13 is provided on the workbench 1 and is penetrated in the sliding hole 2241. The cooperation between the limiting rod 13 and the sliding hole 2241 is used to limit the displacement distance of the lifting plate, thereby limiting the displacement of the drill 21.

[0050] Specifically, there are multiple drills 21, the first motor 221 is consistent with the number of motors, and one first motor 221 controls the rotation of one drill 21. Multiple drills 21 can further improve the working efficiency of the wire binding machine and reduce labor costs. Independently controlling the rotation of a single 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. The independent control of a single drill 21 can prevent a failure of a drill 21 from affecting the overall working efficiency of the wire binding machine. In actual production, each drill 21 can also be independently raised and lowered through structural design.

[0051] Specifically, the second driving assembly 32 includes a third motor 321, a second gear rack module 322 connected to the output shaft of the third motor 321, and a second lifting plate 323 connected between the second gear rack module 322 and the paper pressing board 31. The third motor 321 drives the second lifting plate 323 via the second gear rack module 322 to link the paper pressing board 31 to move up and down to press or release the workpiece to be bound on the workbench 1.

[0052] Specifically, a carrier plate 12 for carrying the workpiece to be bound is provided in the middle of the workbench 1, and a clearance hole 121 for accommodating a drill 21 and a clearance gap (not shown in the figure) are provided on the carrier plate 12, and a slide plate assembly 4 for cooperating with the carrier plate 12 is provided on one side of the clearance hole 121; the slide plate assembly 4 includes a fourth motor 41, a third gear rack module 42 and a transverse plate 43, the fourth motor 41 is connected to the transverse plate 43 via the third gear rack module 42 and drives the transverse plate 43 to reciprocate relative to the carrier plate 12, and a receiving groove 430 is provided on the transverse plate 43, and a silicone pad 431 is detachably installed in the receiving groove 430, and the silicone pad 431 is used to increase the friction between the workpiece to be bound and the carrier plate 12 during the online assembly process to prevent the workpiece to be bound from being offset.

[0053] Both ends of the accommodating groove 430 are provided with gripping positions 4301, which are convenient for the operator to replace the silicone pad 431 according to the situation. In this embodiment, two micro switches are provided at the bottom of the transverse plate 43, and a contact plate is provided on the rack in the third gear rack set. The contact plate is located between the driving rods of the two micro switches, which restricts the transverse plate 43 to reciprocate between the two micro switches, preventing the transverse plate 43 from being excessively displaced or not displaced in place to affect the binding quality of the wire binding machine.

[0054] In this solution, the lifting and lowering of the drill 21, the paperboard 31, the push rod 55, and the lateral movement of the transverse plate 43 are all achieved by using a motor in combination with a gear rack; during the online installation process, the movement of the drill 21, the paperboard 31, etc. usually requires very precise control in order to ensure the accuracy and quality of the binding. Compared with transmission groups such as hydraulics and telescopic cylinders, the gear rack transmission group can achieve precise speed and force control by designing a suitable gear ratio. In addition, the gear rack transmission group is easier to maintain and has higher durability and reliability. In a high-frequency, high-load working environment such as online installation, the drill 21, the paperboard 31, the transverse plate 43, and the push rod 55 after using this mechanism can operate stably for a long time without easily failing, and only needs to be lubricated and cleaned regularly.

[0055] Specifically, an ejector assembly 5 used in conjunction with the drill 21 is provided below the workbench 1, and the ejector assembly 5 includes a fifth motor 51, a fourth gear rack module 52, a guide rod 53, an ejector seat 54, and an ejector rod 55 provided on the ejector seat 54; the guide rod 53 is fixedly mounted on the bottom of the workbench 1, and the ejector seat 54 is slidably provided on the guide rod 53 via the fourth gear rack module 52. The fifth motor 51 drives the ejector seat 54 to reciprocate the ejector via the fourth gear rack module 52, so that the ejector passes through the clearance hole 121 for auxiliary positioning and auxiliary chip removal of the drill 21. Before the binding is started, the ejector rod 55 is in a stationary state.

[0056] The central axes of the push rod 55, the clearance hole 121, and the drill 21 overlap with each other. When the binding is started, the push rod 55 not only plays the role of threading, but also can pass through the hollow part of the drill 21 when the push rod 55 and the drill 21 are close to each other, and further penetrate the ticket material below the drill 21 to prevent the drill 21 from deviating from the punching position. In the actual binding process, the push rod 55 passes through the hollow part of the drill 21 and can also push the paper scraps in the drill 21 upward to prevent the paper scraps from falling. In this embodiment, a micro switch that cooperates with the ejector assembly 5 is provided at the bottom of the carrier plate 12. When the ejector seat 54 moves up and contacts the driving rod of the micro switch, the fifth motor 51 of the ejector assembly 5 will automatically cut off the power to stop the displacement of the ejector seat 54 and the push rod 55.

[0057] Specifically, in this embodiment, a first mounting plate 14 is provided above the carrier plate 12, the first drive assembly 22 is arranged on the workbench 1 via the first mounting plate 14, a second mounting plate 15 is provided below the workbench 1, and the ejector assembly 5 and the slide assembly 4 are arranged on the workbench 1 via the second mounting plate 15. Two telescopic rods 16 are provided between the first mounting plate 14 and the carrier plate 12, and three first motors 221 are connected by a connecting plate 17, and then are slidably arranged on the first mounting plate 14 via the telescopic rods 16 and the first gear rack module 223, and a micro switch is provided between the connecting plate 17 and the first mounting plate 14, and the micro switch is used for power-off braking when the three first motors 221 return to the first mounting plate 14 (punching operation is completed). In this embodiment, the outer cover of the workbench 1 is provided with a shell 8 for maintenance of the internal mechanism.

[0058] Specifically, in this embodiment, the support plate 12 is provided with an avoidance groove 122 connected to the give way hole 121, and the support plate 12 is provided with a wire unwinding reel 7 and an automatic wire cutting assembly 6 used in conjunction with the wire unwinding reel 7 below the support plate 12. The automatic wire cutting assembly 6 includes a cutter mounting plate 61, a push-pull electromagnet 62 arranged on the cutter mounting plate 61, a blade 64 arranged in conjunction with the push-pull electromagnet 62, and a pad 65 arranged at the end of the moving stroke of the blade 64. The blade 64 is installed in conjunction with the push-pull electromagnet 62 through a blade connecting plate 63. In actual use, the blade on the blade connecting plate 63 is controlled by the thrust of the push-pull electromagnet 62 to cut off the wire in the wire slot 122 and then reset, so that the wire cutting is fast, the structure is simple and the stability is good.
