Description

Technical Field

[0001] This utility model relates to the field of binding equipment, and in particular to a portable hot melt riveting and sealing device. Background Technology

[0002] After the vouchers are sorted out, they are usually bound by punching holes, sewing, and corner binding. Since this process is cumbersome and labor-intensive, a hot-melt riveting binding machine has emerged in the existing technology. This machine punches holes in the vouchers, inserts them into riveting tubes, and heats them until both ends of the riveting tubes melt to bind the vouchers.

[0003] However, existing riveting and sealing equipment is generally expensive, typically integrating a drilling machine with heat sealing functionality. In such cases, traditional drilling equipment becomes completely obsolete, and its high purchase cost limits its application. This is especially problematic for companies using outsourced accounting models, where such equipment is bulky and inconvenient to carry. Currently, there is no corresponding solution to this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a portable hot melt riveting tube packaging device that can be used in conjunction with existing drilling equipment to directly bind vouchers using riveting tubes.

A switch is also provided on the outside of the power supply assembly box, and the switch is electrically connected to the power supply module.

[0006] The effect achieved is that when the switch is turned on, the power supply module and the electric heating element form a circuit; the pressure plate is pushed to move towards the power assembly box, so that the two electric heating elements respectively attach to the exposed end face of the rivet tube until the rivet tube melts and forms a seal.

[0007] The beneficial effects of this utility model are: This utility model solves the drawbacks of high manufacturing cost and inconvenience of carrying out hot melt riveting packaging equipment in the prior art. It realizes hot melt packaging of riveting tubes with a simple structure. In particular, the equipment has a simple structure, low cost, and is easy to carry. It can be used with hand-cut riveting tubes to achieve the packaging of vouchers at a very low cost. Attached Figure Description

Detailed Implementation

[0009] Reference Figure 1 , Figure 2 and Figure 3 The portable hot melt riveting and packaging device of this utility model includes a power assembly box 6, which is the basic assembly component of this device. A telescopic link 3 is provided on the top of the power assembly box 6, and a pressure plate 1 is provided at the end of the telescopic link 3; The pressure plate 1 is provided with an electric heating element B8 and an electric heating element A7 on its lower side and opposite to the upper side of the power assembly box 6. The electric heating element A7 and the electric heating element B8 are electrically connected to the power supply module, and the power supply module is integrated into the inner cavity of the power assembly box 6. A switch 5 is also provided on the outside of the power assembly box 6, and the switch 5 is electrically connected to the power supply module.

[0010] The effect achieved is that switch 5 opens the power supply module and forms a circuit with the electric heating element; the device is placed flat, that is, the certificate is placed vertically to ensure that the length of the exposed rivet tubes on both sides of the encapsulation hole is basically the same; the pressure plate 1 is pushed to move towards the power assembly box 6, so that the two electric heating elements respectively attach to the exposed end face of the rivet tube until the rivet tube melts to form an encapsulation.

[0011] In Example 1, the power supply module is a rechargeable battery, and a charging interface 4 is also provided on the power assembly box 6.

[0012] The effect achieved is to further improve the ease of use and portability of the device.

[0013] In Example 2, the telescopic connecting rod 3 is a tubular structure, including an inner tube and an outer tube, and both the inner tube and the outer tube are square tubes. The outer surface of the inner tube and the inner surface of the outer tube are tightly fitted together, and limit rings are respectively provided on the inner and outer tubes.

[0014] The effect achieved is that the square tube telescopic linkage 3 can prevent the pressure plate 1 from rotating with the power assembly box 6; the limiting ring can prevent the inner and outer tubes from separating.

[0015] In embodiment 3, a spring 2 is also sleeved on the outside of the telescopic connecting rod 3, and the two ends of the spring 2 are respectively attached to the bottom of the pressure plate 1 and the top of the power supply assembly box 6.

[0016] This achieves the effect of the equipment automatically returning to its original position.

[0017] Example 4, refer to the accompanying drawings in the specification. Figure 2 A heat insulation sheet 10 is fixedly installed on the top of the power supply assembly box 6, and a guide rod 9 is fixedly installed in the center of the heat insulation sheet 10. The electric heating element A7 is sleeved on the guide rod 9, and the inner hole of the electric heating element A7 is tightly fitted with the guide rod 9. The electric heating element A7 is disposed on the heat insulation sheet 10. A heat insulation sheet 10 is provided under the pressure plate 1, and the electric heating element B8 is fixedly provided under the heat insulation sheet 10; and the heat insulation sheet 10 and the electric heating element B8 are provided with through holes that fit tightly against the outer wall of the guide rod 9.

[0018] Preferably, the guide rod 9 is disposed in contact with the inner surface of the rivet tube.

[0019] Furthermore, both the heat insulation sheet 10 and the guide rod 9 are made of quartz.

[0020] The effect achieved is that the guide rod 9 is inserted into the rivet tube during use, and is set to fit the guide rod 9 based on the inner hole on the electric heating plate. During the pressing process, the molten part of the rivet tube overflows to the outside of the guide rod 9, forming an encapsulation.

[0021] Example 5, refer to the accompanying drawings in the specification. Figure 2 The power supply module is connected to the electric heating element A7 and the electric heating element B8 by wires, and a wire fixing clip 12 is provided on the wires near the power supply module and the electric heating element A7 and the electric heating element B8. A cable reel 11 is integrated within the pressure plate 1. The cable reel 11 mentioned here is the automatic rewinding cable reel 11 in the prior art that uses a spring 2 or a clockwork as a power element.

[0022] The effect achieved by this is that the cable reel 11 and the cable clip 12 can adapt to the extension and retraction of the telescopic link 3, and avoid pulling on the cable connection point, which would affect the service life of the equipment.

[0023] Preferably, the telescopic connecting rod 3 is a hollow sleeve structure, and a winding pulley is provided on the bottom surface of the inner cavity of the power assembly box 6 corresponding to the position of the telescopic connecting rod 3; the wire between the power supply module and the electric heating element B8 passes through the winding pulley and the winding device 11 in sequence, and is electrically connected to the electric heating element B.

[0024] This achieves the effect of preventing wires from wearing out.

[0025] Preferably, the winding pulley can be replaced by the wire clip 12.
