Description

Technical Field

[0001] The utility model relates to the technical field of binding machines, in particular to a three-hole wire binding machine with a simplified chip removal structure. Background Art

[0002] A binding machine is used to drill holes in documents and bind them using rivet tubes or wire ropes. When drilling, paper scraps will enter the drill bit and be discharged from bottom to top. In order to prevent the discharged paper scraps from splashing, a chip box is often required to accommodate the paper scraps. Traditional binding machines movably install the chip box at the bottom of the binding machine. However, for wire binding machines, in addition to setting a drilling device on the upper part of the frame, a threading device is also required to be set at the lower part. If the chip box is set below the threading device, the height of the entire machine will be too high. In addition, for three-hole wire binding machines, the paper scraps discharged by the three drills need to be retained in the drilling device for convergence first, and then discharged through the chip discharge channel. The chip discharge structure is complex, and one chip discharge channel discharges the paper scraps generated by the three drills at the same time. The chip discharge speed is slow, the efficiency is low, and it is easy to cause the chip discharge channel to be blocked.

[0003] To solve this problem, for example, Chinese utility model patent: CN201920577767.9, a multi-hole wire binding machine with an improved drilling mechanism, the drilling mechanism includes a drilling guide seat and a paper scrap box, the drilling guide seat is slidably mounted on the drilling guide rod, the interior of the drilling guide seat is hollowed out to form a mounting cavity, the mounting cavity is equipped with at least one drilling device with at least one chip removal opening, the mounting cavity is provided with at least one paper scrap outlet running through the inside and outside; the paper scrap box is movably mounted on the bottom of the drilling guide seat, and the paper scrap box is connected to the paper scrap outlet. This patent movably mounts the paper scrap box on the drilling guide seat, thereby reducing the vertical height occupied, but due to the limited size of the drilling guide seat, the paper scrap box of this patent is small in size, resulting in a small capacity, requiring frequent cleaning of the paper scrap box, and inconvenient to use. Moreover, when drilling, the paper scrap box will move up and down with the drilling guide seat, which will cause additional load on the drive device, resulting in serious heating of the drive device, high energy consumption, poor reliability and stability, so it is necessary to improve it.

[0034] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0035] A three-hole wire-mounted machine with a simplified chip removal structure, such as Figures 1 to 6 As shown, it includes a frame, a drilling device and a threading device. A binding platform 141 is provided in the middle of the frame. The drilling device is provided at the upper part of the frame, and the threading device is provided at the lower part of the frame. The drilling device is provided with a drilling slide 2 and at least one drilling component 3. The drilling component 3 is installed on the drilling slide 2. The drilling slide 2 is installed on the upper part of the frame for sliding up and down. The threading device is provided with a threading slide 51 and at least one threading needle 52. The threading slide 51 is installed on the lower part of the frame for sliding up and down. The threading needle 52 is fixedly installed on the threading slide 51. A chip box 6 is movably installed at the lower part of the frame. The chip box 6 Arranged on the rear side of the threading device, the interior of the drilling slide 2 is provided with at least one chip removal chamber 21, the lower part of the drilling slide 2 is provided with at least one chip guide port 22, the drilling assembly 3 is provided with an upper chip removal port 321, the upper chip removal port 321 and the chip guide port 22 are respectively connected with the chip removal chamber 21, at least one chip removal tube 7 is provided between the drilling slide 2 and the chip box 6, the binding platform 141 is provided with at least one through-tube hole 142 passing through the binding platform 141, the upper end of the chip removal tube 7 is connected with the chip guide port 22, and the lower end of the chip removal tube 7 passes through the through-tube hole 142 and extends to directly above the chip box 6.

[0036] The chip box 6 of the traditional three-hole thread-binding machine is either installed on the drilling slide 2 or under the threading device. When it is installed on the drilling slide 2, the chip box 6 has a small capacity and needs to be cleaned frequently. The load of the drilling drive mechanism is large. When it is installed under the threading device, it occupies vertical space, resulting in a large volume of the whole machine. In addition, the paper scraps generated by the three drilling assemblies 3 are often first gathered in the same chamber and then discharged into the chip box 6 through a single channel. The chip removal structure is complicated, the chip removal efficiency is low, and it is easy to get blocked. The utility model installs the chip box 6 on the rear side of the threading device. It does not occupy vertical space, reduces the size of the entire machine, increases the volume of the chip box 6, reduces the number of cleaning times, and improves ease of use; paper scraps are guided to the chip box 6 through the chip discharge pipe 7 to prevent them from splashing when they fall, which is clean and hygienic; each drilling component 3 corresponds to a chip discharge chamber 21, and paper scraps enter the chip discharge chamber 21 from the upper chip discharge port 321, and then enter the chip discharge pipe 7 from the chip guide port 22, and enter the chip box 6 through the chip discharge pipe 7. The paper scraps generated by each drilling component 3 are discharged into the chip box 6 independently without the need for convergence, which simplifies the chip discharge structure, improves the chip discharge efficiency, and prevents blockage.

[0037] Specifically, if Figure 3 As shown, the chip guide opening 22 is arranged in front of the tube hole 142 along the longitudinal direction. The chip guide opening 22 and the tube hole 142 are staggered front and back. The chip removal tube 7 is provided with an upper chip removal segment 71 and a lower chip removal segment 72 from top to bottom. The upper chip removal segment 71 is located between the chip guide opening 22 and the tube hole 142. The lower end of the lower chip removal segment 72 extends to directly above the chip receiving box 6. The upper chip removal segment 71 is arranged at an angle, and the clamping foot α between the upper chip removal segment 71 and the axis of the drilling assembly 3 is 10 to 30 degrees. The chip guide opening 22 and the tube hole 142 are staggered front and back to tilt the upper chip removal segment 71, forming a buffer for paper scraps, preventing paper scraps from falling directly vertically, and reducing noise. Preferably, the clamping foot α between the upper chip removal segment 71 and the axis of the drilling assembly 3 is 15 to 25 degrees.

[0038] Specifically, if Figure 3 As shown, the through-hole 142 is provided between the chip guide opening 22 and the chip box 6 along the longitudinal direction, and the angle β between the lower chip removal section 72 and the axis of the drilling assembly 3 is 15 to 90 degrees. In order to fully utilize the installation space, the through-hole 142 is provided on the front side of the chip box 6 to avoid excessively large angle α between the upper chip removal section 71 and the axis of the drilling assembly 3, which may lead to accumulation of paper scraps. Preferably, the angle β between the lower chip removal section 72 and the axis of the drilling assembly 3 is 20 to 60 degrees.

[0039] Specifically, if Figures 2 to 4As shown, at least one fixing member 18 is provided above the chip box 6. The upper portion of the fixing member 18 is fixedly connected to the bottom surface of the binding platform 141, and the lower portion of the fixing member 18 is fixedly connected to the lower chip discharge segment 72. The upper chip discharge segment 71 is fixed by the chip guide port 22 and the through-tube hole 142, while the upper portion of the lower chip discharge segment 72 is fixed by the through-tube hole 142, and the lower portion of the lower chip discharge segment 72 is fixed by the fixing member 18. This prevents the lower chip discharge segment 72 from shaking and being unable to align with the chip box 6, preventing paper scraps from splashing outside the chip box 6, and improving reliability and stability.

[0040] Specifically, the fixing member 18 is a cable tie, and the chip removal pipe 7 is a spring tube. The fixing member 18 is directly fixed with a cable tie, and the angle of the clamping foot β is controlled by adjusting the length of the cable tie, resulting in a simple structure and low cost. The chip removal pipe 7 is a spring tube, which can maintain its connection with the drilling slide 2 during the raising and lowering of the drilling slide 2, avoiding bending and blocking.

[0041] Specifically, the drilling assembly 3 includes a drilling motor 31, a drill sleeve 32 and a drill 33. The drilling motor 31 is fixedly mounted on the top of the drilling slide 2. The upper part of the drill sleeve 32 is fixedly mounted on the output shaft of the drilling motor 31. The upper chip removal port 321 is provided on the side of the drill sleeve 32 and penetrates the drill sleeve 32 inside and outside. The upper chip removal port 321 is located in the chip removal chamber 21. The upper end of the drill 33 is connected to the lower part of the drill sleeve 32. The interior of the drill 33 is provided with a chip removal channel 331 vertically penetrating the drill 33 along the axial direction. The upper end of the chip removal channel 331 is connected to the inner cavity of the drill sleeve 32. When drilling, paper scraps enter the chip removal channel 331. As the number of drilling times increases, the paper scraps in the chip removal channel 331 gradually move upward into the inner cavity of the drill sleeve 32, and then enter the chip removal chamber 21 through the upper chip removal port 321. As the drilling slide 2 rises and falls and vibrates, the paper scraps enter the chip removal tube 7 through the chip guide port 22, and are then discharged into the chip box 6.

[0042] Specifically, the chip guide opening 22 is disposed at the rear side of the bottom surface of the chip discharge chamber 21. The vertical height of the chip guide opening 22 is lower than the vertical height of the upper chip discharge opening 321. The bottom surface of the chip discharge chamber 21 is provided with a guide slope 211 that is inclined toward the chip guide opening 22. Since the chip guide opening 22 is lower than the upper chip discharge opening 321, paper scraps can enter the chip guide opening 22 from top to bottom and be discharged from the chip discharge chamber 21 through gravity and vibration. At the same time, the inclined guide slope 211 can guide paper scraps at the bottom of the chip discharge chamber 21 to prevent paper scraps from accumulating in the chip discharge chamber 21.

[0043] Specifically, the frame includes a door frame 11, a support box 14, a driving vertical plate 12, a driving bottom plate 15, at least two drilling guide columns 13 and at least two threading guide columns 16, a binding platform 141 is provided on the upper end surface of the support box 14, the door frame 11 is fixedly mounted on the binding platform 141, the upper part of the driving vertical plate 12 is fixedly connected to the door frame 11, the lower part of the driving vertical plate 12 is fixedly connected to the binding platform 141, the driving bottom plate 15 is fixedly mounted on the lower part of the support box 14, the upper part of the threading guide column 16 is fixedly connected to the door frame 11, and the threading guide column 16 is fixedly mounted on the bottom plate 15 of the support box 14. The lower portion of the column 16 is fixedly connected to the binding platform 141. The threading guide column 16 is vertically arranged in the support box 14. The drilling slide 2 is slidably mounted on the drilling guide column 13. The threading slide 51 is slidably mounted on the threading guide column 16. The drilling device is also provided with a drilling drive mechanism. The threading device is also provided with a threading drive mechanism 53. The drilling drive mechanism is provided on the driving vertical plate 12 and is transmission-connected to the drilling slide 2. The threading drive mechanism 53 is provided on the driving bottom plate 15 and is located inside the support box 14. The threading drive mechanism 53 is transmission-connected to the threading slide 51. The frame is made of bent plate parts, replacing the traditional bracket structure, simplifying the structure, reducing costs, and simplifying the processing technology.

[0044] Specifically, a pull-out channel 17 is provided at the bottom of the support box 14, and a pull-out opening that passes through the support box 14 inside and outside is provided on one side of the pull-out channel 17. The pull-out channel 17 extends in the horizontal direction and is located at the rear side of the threading device. The chip box 6 includes a box body 61 with an upward opening, a limit seal 62 and a pull-out handle 63. The limit seal 62 is fixedly installed at one end of the box body 61, and the pull-out handle 63 is fixedly installed on the outer side of the limit seal 62. The box body 61 passes through the pull-out opening and is slidably installed in the pull-out channel 17. The limit seal 62 is limited and matched with the outer side of the support box 14. The lower end of the chip discharge pipe 7 extends to just above the box body 61. The chip box 6 is installed on the support box 14 in a drawer-like manner. When cleaning, grab the pull-out handle 63 to pull out the box body 61. When reinstalling, insert the box body 61 into the pull-out channel 17 from the pull-out opening until the limit seal 62 hits the outer side of the support box 14, thereby completing the installation. The cleaning steps are simple and easy to use.

[0045] Specifically, the drilling slide 2 is provided with three drilling assemblies 3 at intervals along the transverse direction, and three chip removal chambers 21 are provided inside the drilling slide 2 at intervals along the transverse direction.

The threading slide 51 is provided with three threading needles 52 along the transverse direction, and each threading needle 52 is aligned with the corresponding drilling cutter 33 in the vertical direction; the drilling drive mechanism includes a drilling lifting motor 41, a drilling drive gear 42 and a drilling drive rack 43.
