A device for recycling waste material from hot melt rods used in voucher binding machines

Abstract

This utility model relates to the technical field of voucher binding machines, and in particular to a device for recycling and utilizing leftover hot melt rods in voucher binding machines. The device includes a binding machine body with a feeding chamber at one top end. When the connecting block is pressed, a return spring is compressed, and a slider slides within a movable frame, causing a pressing cone to move towards the hot melt rod in the feeding chamber and compress it. As the pressing cone compresses the hot melt rod, the sliding movable frame further moves the hot melt rod within the feeding chamber, facilitating the removal of leftover material and completing the recycling of the material. Rotating the adjusting block causes the threaded rod to rotate. As the threaded rod rotates, the pressing block moves axially along the threaded rod. The moving pressing block compresses the triangular blocks on both sides, and the triangular blocks simultaneously compress the compression spring, causing the positioning rod to move and engage with the limiting groove and the limiting block, thereby fixing the heating chamber between two fixed seats. This design is convenient for assembly and disassembly and offers better practicality.

Description

Technical Field

[0001] This utility model relates to the technical field of voucher binding machines, and in particular to a device for recycling and utilizing leftover hot melt rods used in voucher binding machines. Background Technology

[0002] A voucher binding machine is an office device specifically designed for organizing and binding financial vouchers. It uses mechanical or electric methods to fix and bind scattered accounting vouchers, invoices, documents, and other materials according to standardized requirements, aiming to improve the efficiency and standardization of financial file management. Its core function is to organize scattered voucher materials according to chronological order, business category, or numbering rules, and then firmly bind them into a booklet using processes such as punching, threading, heat sealing, or riveting. This facilitates long-term preservation and subsequent retrieval. Traditional manual binding methods require manual punching and threading, which is not only time-consuming and labor-intensive but also produces inconsistent binding results. The advent of voucher binding machines has greatly simplified the process through automated design. Users only need to place the organized vouchers into the designated position, and the machine will automatically complete the punching and binding steps. Some high-end models also support functions such as adjustable binding thickness, automatic tube cutting, and intelligent positioning, adapting to the binding needs of vouchers of different sizes and thicknesses.

[0003] Traditional voucher binding machines often have a section of glue stick left over after use, which is inconvenient to use and leads to waste. In addition, sometimes staff need to manually remove it with tools to replace the long glue stick, which is not very practical and has certain drawbacks. Utility Model Content

[0004] The purpose of this invention is to provide a device for recycling and utilizing leftover hot melt rods from a voucher binding machine, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for recycling waste material from hot melt rods used in a voucher binding machine, comprising a binding machine body, a feeding chamber at one top end of the binding machine body, a groove communicating with the feeding chamber on the outside of the binding machine body, a movable frame inside the groove, a slider inside the movable frame, an extrusion cone at one end of the slider near the feeding chamber, two fixed seats on the narrower side of the outer surface of the binding machine body, limit grooves on both sides of one outer end of the fixed seats, a heating chamber between the two fixed seats, limit blocks at both ends of the heating chamber and inside the corresponding limit grooves, and a heating cavity at the top of the heating chamber.

[0006] Preferably, a fixed frame is installed on the outside of the binding machine body and on the slide groove. Guide grooves are provided at both ends of the fixed frame. Guide posts are installed at both ends of the movable frame and inside the two guide grooves. When the movable frame slides outside the slide groove and the fixed frame, the guide posts slide synchronously inside the guide grooves.

[0007] Preferably, a connecting block is installed at one outer end of the slider, the outer ring surface of the slider is slidably connected to the inner sidewall of the movable frame, and a return spring is installed at both outer ends of the connecting block and between the two sides located at one end of the movable frame.

[0008] Preferably, the outer side dimensions of the limiting block are adapted to the inner side wall dimensions of the limiting groove, and when the heating chamber is located between two fixed seats, the limiting blocks on both sides are simultaneously connected to the inside of the limiting groove.

[0009] Preferably, the fixed seat has an installation groove inside and between the two limiting grooves. A threaded rod is installed between the inner walls of the installation groove. One end of the threaded rod passes through the outside of the fixed seat and is fitted with an adjusting block. An extrusion block is installed on the outer ring surface of the threaded rod and close to the inner wall of the installation groove.

[0010] Preferably, triangular blocks are provided inside the mounting groove and on both sides of the extrusion block, a compression spring is installed outside the triangular blocks and between the inner walls of the mounting groove, and a positioning rod is installed outside the triangular blocks and inside the compression spring. The end of the positioning rod away from the triangular blocks extends into the limiting groove and connects to the inside of the limiting block.

[0011] In summary, this utility model has the following beneficial technical effects:

[0012] This device for recycling leftover hot melt rods in a voucher binding machine involves pressing a connecting block, compressing a return spring, and sliding a slider within a movable frame to move an extrusion cone towards the hot melt rod in the feeding chamber. As the extrusion cone extrudes the hot melt rod, the sliding movable frame further moves the hot melt rod within the feeding chamber, facilitating the removal of leftover material and completing its recycling. Rotating an adjusting block rotates a threaded rod, causing the extrusion block to move axially along the threaded rod. As the extrusion block moves, it extrudes the triangular blocks on both sides. The movement of the triangular blocks simultaneously extrudes and compresses the spring, and also moves a positioning rod to engage with the inside of a limiting groove and then with the inside of a limiting block, thereby fixing the heating chamber between two fixed seats. This design is convenient for assembly and disassembly and offers superior practicality. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 - Figure 6 The present invention will be described in further detail below.

[0021] A device for recycling waste material from hot melt rods used in voucher binding machines, referring to Figure 1 - Figure 6 The binding machine includes a binding machine body 1. A feeding chamber 2 is provided at one top end of the binding machine body 1. A sliding groove 101 is provided on the outside of the binding machine body 1, communicating with the feeding chamber 2. A movable frame 3 is provided inside the sliding groove 101. A slider 4 is installed inside the movable frame 3. An extrusion cone 5 is installed at one end of the slider 4, near the feeding chamber 2. Two fixed seats 6 are installed on the narrower side of the outer surface of the binding machine body 1. Limiting grooves 601 are provided on both sides of one outer end of the fixed seat 6. A heating chamber 7 is installed between the two fixed seats 6. Limiting blocks 8 are installed at both ends of the heating chamber 7, inside the corresponding limiting grooves 601. A heating chamber 9 is provided at the top of the heating chamber 7. The feeding chamber 2 is used to hold hot melt rods for use. The heating chamber 9 can heat and melt the recycled hot melt rod residue, facilitating subsequent reshaping and reuse, thus realizing the recycling of the residue.

[0022] Reference Figure 1 - Figure 5A fixed frame 10 is installed on the outside of the binding machine body 1 and on the slide groove 101. Guide grooves 1001 are provided at both ends of the fixed frame 10. Guide posts 11 are installed at both ends of the movable frame 3 and inside the two guide grooves 1001. When the movable frame 3 slides outside the slide groove 101 and the fixed frame 10, the guide posts 11 slide synchronously inside the guide grooves 1001. When the movable frame 3 slides along the slide groove 101, the guide posts 11 move synchronously within the guide grooves 1001 of the fixed frame 10. The cooperation between the guide posts 11 and the guide grooves 1001 restricts the movement direction of the movable frame 3, preventing it from deviating from or detaching from the slide groove 101, ensuring that the movable frame 3 drives the slider 4 and the extrusion cone 5 to stably and accurately approach the hot material in the feeding chamber 2. The hot melt rod improves the accuracy of the residual material ejection operation. A connecting block 12 is installed on one end of the slider 4. The outer ring surface of the slider 4 is slidably connected to the inner side wall of the movable frame 3. A return spring 13 is installed between the two outer ends of the connecting block 12 and the two sides located at one end of the movable frame 3. When the connecting block 12 is pressed, the return spring 13 is compressed. The slider 4 slides in the movable frame 3, driving the extrusion cone 5 to move towards the hot melt rod in the feeding chamber 2 to extrude the hot melt rod. After the connecting block 12 is released, the return spring 13 returns to its deformation, pushing the slider 4 and the extrusion cone 5 to reset and prepare for the next operation. When the extrusion cone 5 extrudes the hot melt rod, the sliding movable frame 3 can further drive the hot melt rod to move in the feeding chamber 2, which facilitates the sliding of residual material out of the feeding chamber 2 and completes the recycling of residual material.

[0023] Reference Figure 1 - Figure 3 The outer side dimensions of the limiting block 8 are adapted to the inner side wall dimensions of the limiting groove 601. When the heating chamber 7 is located between the two fixed seats 6, the limiting blocks 8 on both sides are simultaneously connected to the inside of the limiting groove 601. When installing the heating chamber 7, the limiting blocks 8 at both ends of the heating chamber 7 are aligned with the limiting groove 601 of the fixed seat 6. Since the outer side dimensions of the limiting block 8 are adapted to the inner side wall dimensions of the limiting groove 601, the limiting block 8 can be smoothly connected to the limiting groove 601, realizing the initial positioning of the heating chamber 7 between the fixed seats 6, preventing the heating chamber 7 from moving horizontally, and ensuring that the heating chamber 7 is accurately installed on the binding machine body 1.

[0024] Reference Figure 1 - Figure 6An installation groove 602 is provided inside the fixed base 6 and between the two limiting grooves 601. A threaded rod 14 is installed between the inner walls of the installation groove 602. One end of the threaded rod 14 passes through the outside of the fixed base 6 and is fitted with an adjusting block 15. An extrusion block 16 is installed on the outer ring surface of the threaded rod 14 and close to the inner wall of the installation groove 602. Rotating the adjusting block 15 causes the threaded rod 14 to rotate. Since the threaded rod 14 and the extrusion block 16 are threadedly connected, the extrusion block 16 moves axially along the threaded rod 14 when the threaded rod 14 rotates. Triangular... A compression spring 18 is installed on the outside of the triangular block 17 and between the inner walls of the mounting groove 602. A positioning rod 19 is installed on the outside of the triangular block 17 and inside the compression spring 18. The end of the positioning rod 19 away from the triangular block 17 extends into the interior of the limiting groove 601 and connects into the interior of the limiting block 8. When the pressing block 16 moves, it will press the triangular blocks 17 on both sides. The movement of the triangular blocks 17 will simultaneously press the compression spring 18 and drive the positioning rod 19 to move and connect into the interior of the limiting groove 601 and connect into the interior of the limiting block 8, thereby fixing the heating chamber 7 between the two fixed seats 6, which is convenient for disassembly and assembly.

[0025] The implementation principle of the hot melt rod waste recycling device for a voucher binding machine according to this utility model embodiment is as follows: When using the device, the feeding chamber 2 is used to place the hot melt rod for use. When the connecting block 12 is pressed, the return spring 13 is compressed, and the slider 4 slides in the movable frame 3, driving the extrusion cone 5 to move towards the hot melt rod in the feeding chamber 2 to extrude the hot melt rod. After releasing the connecting block 12, the return spring 13 returns to its deformation, pushing the slider 4 and the extrusion cone 5 back to their original positions to prepare for the next operation. When the extrusion cone 5 extrudes the hot melt rod, it moves through the slider... The movable frame 3 can further drive the hot melt rod to move within the feeding chamber 2, facilitating the sliding out of the feeding chamber 2 of the residual material and completing the recycling of the residual material. When the movable frame 3 slides along the slide groove 101, the guide column 11 moves synchronously within the guide groove 1001 of the fixed frame 10. The cooperation between the guide column 11 and the guide groove 1001 restricts the movement direction of the movable frame 3, preventing it from deviating or detaching from the slide groove 101. This ensures that the movable frame 3 drives the slider 4 and the extrusion cone 5 to stably and accurately approach the hot melt rod within the feeding chamber 2, thereby lifting and ejecting the residual material. For accurate operation, the heating chamber 9 can heat and melt the recycled hot melt rod residue, facilitating subsequent reshaping and reuse, thus achieving the recycling of residue. When installing the heating chamber 7, align the limiting blocks 8 at both ends of the heating chamber 7 with the limiting grooves 601 of the fixed base 6. Since the outer dimensions of the limiting block 8 are compatible with the inner wall dimensions of the limiting groove 601, the limiting block 8 can smoothly enter the limiting groove 601, achieving the initial positioning of the heating chamber 7 between the fixed bases 6, preventing the heating chamber 7 from moving horizontally, and ensuring that the heating chamber 7 is accurately installed on the binding machine. On the main body 1, rotating the adjusting block 15 drives the threaded rod 14 to rotate. Since the threaded rod 14 is threadedly connected to the extrusion block 16, the extrusion block 16 moves along the axial direction of the threaded rod 14 when the threaded rod 14 rotates. When the extrusion block 16 moves, it will extrude the triangular blocks 17 on both sides. The movement of the triangular blocks 17 synchronously extrudes the compression spring 18 and drives the positioning rod 19 to move and enter the interior of the limiting groove 601 and the interior of the limiting block 8, thereby fixing the heating chamber 7 between the two fixed seats 6. It is convenient to disassemble and assemble and has better practicality.
