Description

Technical Field

[0001] This utility model relates to the field of binding and punching equipment technology, and in particular to a ticket binding and punching device. Background Technology

[0002] Binding and punching documents is a routine operation in financial and accounting offices. It involves precise punching and binding to achieve standardized archiving and management of documents (such as vouchers, reports, contracts, etc.).

[0003] Traditional equipment uses a single-drill clamp design, which can only drill one hole at a time. Double-hole binding requires manual repositioning and secondary drilling. The processing time for a single document is ≥30 seconds, and batch processing (such as 500 documents) takes more than 4 hours. The efficiency is difficult to meet the high-frequency demand. In addition, the document specifications are becoming increasingly diverse (from the standard A4 size to A3 reports, narrow-width stubs, etc.), which puts forward higher requirements for drilling efficiency, hole position accuracy and equipment compatibility. Summary of the Invention

[0004] This utility model provides a document binding and punching device. The extended drill chuck and the main drill chuck rotate synchronously to punch holes in the document, and can complete the opening of two holes at once. Compared with the traditional single-hole equipment's "single hole per operation" mode, the punching efficiency is increased by more than 100%, further shortening the document binding and punching time. By moving the extended drill chuck away from the main drill chuck with the side extension bracket, and adjusting the angle of the extended drill chuck with the side extension bracket, the distance and tilt angle between the extended drill chuck and the main drill chuck can be adjusted, adapting to various document binding standards.

[0005] This utility model provides a document binding and punching device, specifically including: a main frame, a punching module, and a side expansion bracket. The punching module is vertically slidably connected to the upper part of the main frame, and a side expansion bracket is provided at the lower part of the punching module. A front expansion plate is horizontally slidably connected to the front side of the main frame. The plane and worktable of the main frame are used to place documents. The front expansion plate is horizontally slidably adjustable to extend the length of the worktable, adapting to the placement and positioning of extra-long documents (such as A3 reports), and avoiding punching offset caused by the documents being suspended. A plastic binding module is vertically slidably connected to the left side of the main frame. The plastic binding module includes a heating plate and a pressing component. The heating temperature is 150-200℃. The plastic binding module is used to heat-press and fix the binding tube. Pressure rods are rotatably connected to both the left and right sides of the main frame. The middle groove of the pressure rod on the left side of the main frame is slidably connected to the side protrusion of the plastic binding module, and the middle groove of the pressure rod on the right side of the main frame is slidably connected to the side protrusion of the punching module. Pressing down the pressure rods on both sides can drive the plastic binding module and the punching module to descend vertically.

[0006] Furthermore, the bottom of the hole-opening module is vertically slidably connected to a lower positioning frame, and an upper support spring is fixedly connected between the lower positioning frame and the hole-opening module. The bottom of the hole-opening module is rotatably connected to a main drill chuck driven by a motor. The main drill chuck is compatible with 3-8mm drill bits. The bottom of the hole-opening module is fixedly connected to a lower sliding groove frame. The side of the hole-opening module is rotatably connected to a side threaded rod, and the side of the hole-opening module is horizontally slidably connected to a side sliding groove extension slide.

[0007] Furthermore, the middle part of the side expansion bracket is rotatably connected to an expansion threaded rod, the front end of the side expansion bracket is slidably connected to a front connecting frame, the lower part of the side expansion bracket is rotatably connected to an expansion drill chuck, the expansion drill chuck is adapted to 3-8mm drill bits, the front end of the side expansion bracket is fixedly connected to a sliding groove connecting frame, the middle part of the sliding groove connecting frame is slidably connected to a central rotating shaft frame, and the lower end of the central rotating shaft frame is circumferentially rotatably connected to an inter-gear.

[0008] Furthermore, the side threaded rod and the first end of the side slide groove extension carriage are threadedly connected, the top of the side extension bracket and the side slide groove extension carriage are slidably connected, and rotating the side threaded rod can drive the side slide groove extension carriage to slide horizontally, thereby adjusting the angle between the extension drill chuck and the main drill chuck to meet the binding requirements of multiple specifications of documents.

[0009] Furthermore, the first end of the first connecting frame is rotatably connected to the bottom of the opening module, the first connecting frame is threadedly connected to the extension threaded rod, the extension threaded rod moves axially along the threaded hole of the first connecting frame, the first connecting frame and the side extension bracket move away from the main drill chuck synchronously, and the extension drill chuck moves away from the main drill chuck along with the side extension bracket, thereby realizing the adjustment of the distance between the extension drill chuck and the main drill chuck.

[0010] Furthermore, the upper end of the central rotating shaft frame and the sliding groove of the lower sliding groove frame are slidably connected, and one side of the inter-gear is meshed with the upper gear of the expansion drill chuck. When the side expansion bracket moves to expand, the lower sliding groove frame guides the central rotating shaft frame to slide along the sliding groove connecting frame, so that the inter-gear is always close to the expansion drill chuck and the main drill chuck.

[0011] Furthermore, the other side of the intermediate gear is meshed with the upper gear of the main drill chuck, and the intermediate gear is always meshed with the main drill chuck and the extension drill chuck, and the extension drill chuck and the main drill chuck rotate synchronously.

[0012] This utility model provides a document binding and punching device, which has the following beneficial effects: The extended drill chuck and main drill chuck rotate synchronously to punch holes in documents, enabling the opening of two holes in one go. Compared with the traditional single-hole equipment's "single hole per operation" mode, the punching efficiency is increased by more than 100%, further shortening the document binding and punching time, significantly reducing manual operation time, adapting to high-frequency document processing scenarios, and avoiding hole misalignment caused by positioning deviation in traditional step-by-step punching, thus providing a basic guarantee for the neatness of subsequent binding.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Example 1: Please refer to Figures 1 to 6 : This utility model discloses a document binding and punching device, comprising: a main frame 1, a punching module 2, and a side expansion bracket 3. A front expansion plate 101 is horizontally slidably connected to the front side of the main frame 1. The plane of the main frame 1 and the worktable surface 104 are used to place documents. The front expansion plate 101 is horizontally slidably adjustable to extend the length of the worktable surface 104, adapting to the placement and positioning of extra-long documents and avoiding punching offset caused by the documents being suspended. A plastic sealing binding module 102 is vertically slidably connected to the left side of the main frame 1. The plastic sealing binding module 102 includes a heating element and a pressing assembly. The heating temperature is 150-200℃. The plastic sealing binding module 102 is used for heat-pressing and fixing the binding tube. Pressure rods 103 are rotatably connected to both the left and right sides of the main frame 1. The middle groove of the pressure rod 103 on the left side of the main frame 1 connects to the plastic sealing binding module 102. 02 Side protrusion sliding connection, the middle groove of the pressure rod 103 on the right side of the main frame 1 and the side protrusion of the opening module 2 are slidably connected. Pressing down the pressure rods 103 on both sides can drive the plastic sealing module 102 and the opening module 2 to descend vertically. The opening module 2 is vertically slidably connected to the upper part of the main frame 1. The bottom of the opening module 2 is vertically slidably connected to the lower positioning frame 201. The upper support spring 202 is fixedly connected between the lower positioning frame 201 and the opening module 2. The bottom of the opening module 2 is rotatably connected to the main drill chuck 203 driven by the motor. The main drill chuck 203 is adapted to 3-8mm drill bits. The bottom of the opening module 2 is fixedly connected to the lower groove frame 204. The side of the opening module 2 is rotatably connected to the side threaded rod 205. The side of the opening module 2 is horizontally slidably connected to the side groove extension slide 206. The lower part of the opening module 2 is provided with a side expansion bracket 3. An expansion threaded rod 301 is rotatably connected to the middle of the side expansion bracket 3. A first connecting rotating frame 302 is slidably connected to the first end of the side expansion bracket 3. An expansion drill chuck 303 is rotatably connected to the lower part of the side expansion bracket 3. The expansion drill chuck 303 is compatible with 3-8mm drill bits. A sliding groove connecting frame 304 is fixedly connected to the first end of the side expansion bracket 3. A central rotating shaft frame 305 is slidably connected to the middle of the sliding groove connecting frame 304. The lower end of the central rotating shaft frame 305 is rotatably connected to an intermediate gear 306. The first end of the first connecting rotating frame 302 is rotatably connected to the bottom of the opening module 2. The first connecting rotating frame 302 and the expansion threaded rod 301 are threaded together. The expansion threaded rod 301 moves along the first connecting rotating frame 302. As the threaded hole moves axially, the first connecting frame 302 and the side expansion bracket 3 move away from the main drill chuck 203 simultaneously. The expansion drill chuck 303 moves away from the main drill chuck 203 along with the side expansion bracket 3, thus adjusting the distance between the expansion drill chuck 303 and the main drill chuck 203. The upper end of the central rotating shaft frame 305 is slidably connected to the slide groove of the lower sliding groove frame 204. One side of the inter-gear 306 is meshed with the upper gear of the expansion drill chuck 303. When the side expansion bracket 3 moves to expand, the lower sliding groove frame 204 guides the central rotating shaft frame 305 to slide along the slide groove connecting frame 304, so that the inter-gear 306 is always close to the expansion drill chuck 303 and the main drill chuck 203, ensuring the meshing transmission between the inter-gear 306, the expansion drill chuck 303 and the main drill chuck 203.

[0019] In this embodiment, the first end of the side threaded rod 205 and the side slide groove extension slide 206 are threadedly connected, the top of the side extension bracket 3 and the side slide groove extension slide 206 are slidably connected, and rotating the side threaded rod 205 can drive the side slide groove extension slide 206 to slide horizontally, thereby realizing the adjustment of the angle between the extension drill chuck 303 and the main drill chuck 203, which can adapt to the binding needs of multiple specifications of documents.

[0020] In this embodiment, the other side of the intermediate gear 306 is meshed with the upper gear of the main drill chuck 203. The intermediate gear 306 is always meshed with the main drill chuck 203 and the extended drill chuck 303. The extended drill chuck 303 and the main drill chuck 203 rotate synchronously, completing the opening of two holes at once. Compared with the traditional single-hole equipment's "single hole per operation" mode, the drilling efficiency is increased by more than 1 times, further shortening the binding and drilling time of documents and improving work efficiency.

[0021] In this second embodiment, based on the first embodiment, the hole-opening module 2 uses a non-rotating drill bit. The hole-opening module 2 eliminates the need for a motor, and the intermediate gear 306, the central shaft bracket 305, and the slide groove connecting bracket 304 are all unnecessary, reducing the number of parts, lowering production costs, and reducing the failure rate.

[0022] The working principle of this embodiment is as follows: The plane of the main frame 1 and the worktable 104 are used to place the documents. Pressing down the pressure rods 103 on both sides can drive the plastic binding module 102 and the hole-opening module 2 to descend vertically. The lower positioning frame 201 first contacts the document below to realize the pre-positioning operation of the document. Then, the extended drill chuck 303 and the main drill chuck 203 simultaneously perform drilling operations. The extended drill chuck 303 and the main drill chuck 203 rotate synchronously to perform hole-punching operations on the document, which can complete the opening of double holes at one time. Compared with the "single hole" operation mode of traditional single hole equipment, the hole-punching efficiency is increased by more than 1 times, further shortening the binding and hole-punching time of the documents, greatly reducing the manual operation time, adapting to high-frequency document processing scenarios, and ensuring the consistency of the double hole depth. This avoids the hole misalignment caused by the positioning deviation in traditional step-by-step hole punching, and provides a basic guarantee for the neatness of subsequent binding. The extended threaded rod 301 rotates and moves axially along the threaded hole of the first connecting rotating frame 302. The first connecting rotating frame 302 and the side extension bracket 3 move away from the main drill chuck 203 simultaneously. The extension drill chuck 303 moves away from the main drill chuck 203 along with the side extension bracket 3. The thread of the side threaded rod 205 drives the side sliding groove extension slide 206 to move axially. The side sliding groove extension slide 206 drives the side extension bracket 3 and the first connecting rotating frame 302 to rotate around the rotating connection point of the first connecting rotating frame 302 and the opening module 2, thereby realizing the angle adjustment of the extension drill chuck 303 and the side extension bracket 3. The system allows for adjustment of the distance and tilt angle between the extended drill chuck 303 and the main drill chuck 203, meeting requirements such as two-point drilling in the upper left corner or straight-line drilling on the left side. It is compatible with various document binding standards, meeting the binding requirements of "double holes on the left side" and "hole spacing of 80mm" for regular A4 documents; it supports special positioning of extra-large documents such as "double holes in the upper left corner" and "hole spacing of 50mm" for A3 reports; it is compatible with narrow documents such as "double holes on one side near the edge" and "hole spacing of 30mm" for fine drilling, and angled double hole drilling such as 45° tilted holes in the upper left corner of documents, meeting the anti-theft binding requirements of special archives. When the side extension bracket 3 moves and extends, the lower slide bracket 204 guides the central shaft bracket 305 to slide along the slide connecting bracket 304, so that the intermediate gear 306 is always close to the extension drill chuck 303 and the main drill chuck 203, ensuring the meshing transmission between the intermediate gear 306, the extension drill chuck 303 and the main drill chuck 203. The extension drill chuck 303 is driven in a unified manner through the intermediate gear 306 and the main drill chuck 203, reducing the use of independent motors, reducing equipment energy consumption by 40% compared with dual-motor equipment, and simplifying the maintenance process, combining high efficiency and economy.
