Description

Technical Field

[0001] This invention belongs to the field of document binding technology, specifically relating to a punching and threading integrated machine. Background Technology

[0002] Three-hole binding is a common method for binding documents. In practice, you need to first use a three-hole punch to punch holes on the edge of the document, then use a threading needle to pass the two ends of the binding thread through the binding holes at both ends, then pass the middle part of the binding thread through the middle binding hole, and finally tie the two ends of the binding thread through the middle part to complete the binding.

[0003] The existing three-hole punching and threading machine (CN218702287U) is relatively complicated to operate. It requires separate operation of the punching mechanism and the threading mechanism. Furthermore, the drill bit and the threading needle are not on the same axis, and the file needs to be repositioned for both operations.

[0004] The prior art (CN111993808A) discloses an electric three-hole punching and threading binding machine, which sets the drill bit and threading needle coaxially, but still requires the operation of two separate mechanisms to complete the thread binding.

[0005] The existing punching and threading equipment has a relatively complex punching and threading mechanism structure, and the two mechanisms operate separately, which makes the operation more complicated. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a punching and threading machine to simplify the binding operation for users and improve binding efficiency.

[0007] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0008] A punching and threading integrated machine includes a threading mechanism, a punching mechanism, and a paper carrier, with the paper carrier located between the threading mechanism and the punching mechanism. The threading mechanism includes a pressure plate and a threading needle. The pressure plate can press down on the paper carrier and push it toward the punching mechanism to punch holes in the paper. The threading needle is coaxially opposite to the punching position, movably connected to the pressure plate, and equipped with a reset mechanism. It can abut against the paper surface and pass through the binding hole after punching.

[0009] Furthermore, the threading mechanism is movably connected to the paper carrier, and the punching mechanism is located on the underside of the paper carrier and fixed to the base.

[0010] Furthermore, the paper carrier includes a liftable board with four sliding columns erected on the base, and the four corners of the board are slidably connected to the sliding columns via sliding sleeves.

[0011] Furthermore, a lifting spring is fitted onto the sliding column to support the paper-carrying platform.

[0012] Furthermore, the threading needle is positioned vertically downwards, and a thread groove is provided at the lower end of the threading needle.

[0013] Furthermore, a pin spring is provided between the threading needle and the pressure plate to apply downward pressure to the threading needle as a reset mechanism.

[0014] Furthermore, a wing plate is connected to the threading needle, and a pin mechanism is provided on the base. The upper end of the pin mechanism is provided with a pin fork that cooperates with the wing plate. The pin fork is located on the moving path of the threading needle and is used to support the wing plate.

[0015] Furthermore, the ejector pin fork is movably connected to the adjustment bracket, and its height position is adjustable.

[0016] Furthermore, a handle for pressing is attached to the pressure plate.

[0017] Furthermore, the handle is mounted on the base via a bracket, and the handle can be pressed and swung relative to the bracket and is equipped with a return spring. The handle and the pressure plate are linked together via a connecting rod.

[0018] The beneficial effects of this invention are as follows:

[0019] (1) The present invention provides a punching and threading machine. When in use, only one operation is required to complete the entire punching and threading work, which greatly simplifies the operation process and improves the efficiency of binding work.

[0020] (2) In this invention, the threading needle and the brick of the drilling machine are coaxially arranged, which can maximize the alignment of the drilling and threading operations and ensure mechanical precision.

[0021] (3) In this invention, a pin mechanism is set to lift the threading needle off the paper when drilling, so that there is a safe distance between the threading needle and the drill bit, and to prevent accidental damage. Attached Figure Description

[0037] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein similar or identical reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figures 1 to 4 As shown, the punching and threading integrated machine of the present invention includes a pressing mechanism 1, a threading mechanism 2, a paper carrier 4, and a punching mechanism 5. The threading mechanism 2 is on top, the punching mechanism 5 is on the bottom, the paper carrier 4 is located between the threading mechanism 2 and the punching mechanism 5, and the pressing mechanism 1 is used to drive the threading mechanism 2 and the paper carrier 4 to press down.

[0039] The paper carrier 4 includes a worktable 401 for holding papers to be bound, and the worktable 401 is vertically and flexibly placed on a base 6. The base 6 includes a base plate 601 with four vertical sliding pillars 602. Sliding sleeves 402 are provided at the four corners of the worktable 401, and these sleeves are fitted onto the sliding pillars 602, allowing them to slide and rise along the pillars 602. A lifting spring 603 is also fitted onto each sliding pillar 602; the lifting spring 603 is located between the base plate 601 and the sliding sleeves 402, and provides support for the paper carrier 4.

[0040] The punching mechanism 5 is specifically an electric drill 501, which is fixed to the base plate 601 via a connecting bracket 502 and located below the workbench 401. A notch (or three holes) is provided on one side surface of the workbench 401; the electric drill 501 includes three drill bits (or the number of drill bits may be set according to actual binding needs), arranged side-by-side vertically upwards and directly opposite the notch (or holes); thus, when the workbench 401 moves downwards, the drill bits can punch holes in the paper through the notch (or holes).

[0041] Of course, in addition to electric drills, the punching mechanism 5 can also use other forms such as punching needles to pierce the paper by applying downward mechanical pressure, thereby completing the punching operation.

[0042] Combination Figure 5 As shown, the threading mechanism 2 includes a pressure plate 201, which is vertically connected to the worktable 401 and can press down the paper located on the worktable 401. Three threading needles 203 are provided on one side of the pressure plate 201, and are vertically downwards, each coaxially opposite to a drill bit. The lower end of each threading needle 203 has a thread groove 2031 for carrying the binding thread through the pre-drilled binding holes in the paper.

[0043] The threading needle 203 is movably connected to the pressure plate 201, allowing it to move up and down relative to the pressure plate 201. A push-pin spring 204 is provided on the pressure plate 201 to continuously apply downward pressure to the threading needle 203. For each threading needle 203, a corresponding spring top plate 202 is provided on the pressure plate 201, and a wing plate 2032 is located in the middle of the threading needle 203. The push-pin spring 204 is sleeved on the threading needle 203 and acts between the wing plate 2032 and the spring top plate 202. Furthermore, the wing plate 2032 also serves as a limiting structure to prevent the threading needle 203 from moving excessively downward. Normally, without external force, the threading needle 203 is in the lower position under the action of the push-pin spring 204, at which time the thread groove 2031 is below the pressure plate 201. When subjected to external force, the threading needle 203 moves upward against the push-pin spring 204, and the thread groove 2031 can also move to a position above the pressure plate 201.

[0044] like Figures 1 to 3 As shown, a pin mechanism 3, which cooperates with the threading needle 203, is provided on the base 6, including an adjusting frame 301 and a pin fork 302. The adjusting frame 301 is fixed to the base plate 601; the pin fork 302 is movably connected to the adjusting frame 301 and can be adjusted in height according to usage needs. The upper end of the pin fork 302 has a forked structure; the forked structure is opposite to the wing plate 2032, and when the pressure plate 201 carries the threading needle 203 downward, it can support the wing plate 2032, thereby restricting the threading needle 203 to a certain fixed height position.

[0045] like Figure 1As shown, the pressing mechanism 1 includes a handle 102 and a bracket 101. The bracket 101 is fixed to the base plate 601. The handle 102 is movably connected to the bracket 101 and is connected to the pressure plate 201 via a connecting rod 103; when the handle 102 is pressed, the pressure plate 201 is driven to press down via the connecting rod 103. A return spring 104 is also provided between the handle 102 and the bracket 101 to drive the handle 102 to move upward and return to its original position.

[0046] When using the above-mentioned punching and threading machine, first place the paper to be bound on the worktable 401, with the part to be punched and threaded positioned at the notch in the worktable 401. Then press down the handle 102. During this process:

[0047] 1) The handle 102 drives the pressure plate 201 to press down toward the workbench 401, and the threading needle 203 first contacts the paper; as the pressure plate 201 presses down further, the threading needle 203 is pushed up relative to the pressure plate 201 by the resistance of the paper until the body of the pressure plate 201 begins to contact the paper, and the ejector spring 204 completes the first stage of compression.

[0048] 2) Press the paper down with the pressure plate 201 and press down together with the cutting board 401. At this time, the threading needle 203 continues to move down synchronously with the pressure plate 201 until the wing plate 2032 contacts the pin fork 302.

[0049] 3) As the pressure plate 201 continues to press down, the threading needle 203 is further lifted upward relative to the pressure plate 201 under the support of the pin fork 302, thus gradually moving away from the paper surface, and the pin spring 204 begins the second stage of compression; under this condition, the pressure plate 201 and the cutting board 401 firmly clamp the paper and move it down until it comes into contact with the punching mechanism 5 below, and the drill bit is used to drill a binding hole on the paper surface.

[0050] 4) After punching, release handle 102 upwards, and the pressure plate 201, paper, and cutting board 401 move upwards simultaneously. First, the paper separates from the punching mechanism 5. Then, the lower end of the threading needle 203 begins to contact the paper and carries the binding thread out through the binding hole. After the cutting board 401 rises to its maximum height, the cutting board 401 and the paper on it stop moving, while the pressure plate 201 continues to move upwards. Until the ejector spring 204 is fully reset, the pressure plate 201 drives the threading needle 203 to disengage from the ejector fork 302 and move upwards together. Finally, the threading needle 203 moves upwards away from the binding hole, while the binding thread remains in the paper binding hole due to the friction of the hole wall.

[0051] The above steps complete the entire drilling and threading process; during this process, the operator only needs to press the handle 102 once.
