Description

Technical Field

[0001] This utility model relates to the field of voucher pressing machine technology, specifically a voucher pressing machine that prevents offset. Background Technology

[0002] Financial vouchers are essential documents in financial work and need to be properly preserved for future inspection. To make the vouchers flatter and improve their preservation convenience, a financial voucher pressing machine is usually used. A voucher pressing machine is a device used for printing and pressing vouchers in financial management. After pressing, the vouchers are sealed, which allows for longer preservation and prevents them from falling apart.

[0003] However, since the voucher pressing machine exerts considerable pressure on the voucher when pressing it, and the existing voucher pressing machine does not have a structure to limit the outer edge of the voucher, the voucher paper on the top layer is prone to shifting, which reduces the working quality of the voucher pressing machine. Therefore, the current voucher pressing machine needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a voucher pressing machine that prevents offset, in order to solve the problem mentioned in the background art that the voucher pressing machines on the market do not have a structure to limit the outer side of the voucher, so the voucher paper on the top layer is prone to offset, which reduces the working quality of the voucher pressing machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a voucher pressing machine for preventing offset, comprising a base and a limiting mechanism. A support frame is fixed above the base, a pressure rod is threadedly connected to the middle of the support frame, and a pressure plate is connected to the lower part of the pressure rod via a bearing. A guide rod is fixed between the base and the top of the support frame, and the guide rod is slidably connected to the four corners of the pressure plate. The limiting mechanism is installed at the bottom of the base and includes a first bidirectional lead screw and a second bidirectional lead screw. The first and second bidirectional lead screws are rotatably installed in the inner cavity of the base via bearings. The first and second bidirectional lead screws are arranged in a cross pattern, with the first bidirectional lead screw located above the second bidirectional lead screw. An adjusting handle is fixedly connected to one end of each of the first and second bidirectional lead screws. A slider is threadedly connected to the outer side of each of the first and second bidirectional lead screws, and a limiting plate is connected to the upper part of the slider via a support mechanism.

[0006] Preferably, the support mechanism includes a fixed rod, which is installed above the slider, and a telescopic rod is slidably sleeved inside the fixed rod. A support spring is installed between the lower end of the telescopic rod and the bottom of the fixed rod.

[0007] Preferably, the base is also provided with an adjustment groove for the fixed rod to slide, and each adjustment groove on the base is provided with several docking holes on its outer side. A pad is also provided on the top of the base, and docking blocks that are connected to the docking holes are connected to the four corners of the pad.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. Equipped with a support mechanism and a limiting mechanism, when the pressure plate presses down, the pressure plate squeezes the limiting plate, which in turn squeezes the telescopic rod, causing the telescopic rod to press down on the support spring. This causes the support spring to contract, which in turn moves the limiting plate downwards. This not only limits the movement of the document but also does not affect the pressing process, effectively preventing the top layer of the document from shifting and improving the working quality of the document pressing machine. By rotating the adjustment handle, the adjustment handle drives the first and second double-acting screws to rotate. Subsequently, the slider engages with the first and second double-acting screws, causing the slider to move closer to or further away from each other on the first and second double-acting screws. At the same time, the slider drives the limiting plate to move closer to or further away from each other. The limiting plate abuts against the four corners of the document, which can limit and clamp the document. This allows for the straightening of the document before pressing and facilitates the limiting and pressing of documents of different sizes.

[0010] 2. A pad is provided. After adjusting the position of the limit plate, the pad is placed on the base surface and the mating block is inserted into the mating hole. This prevents the pad from sliding. Furthermore, the pad size can be customized according to different sizes of vouchers through several mating holes, making it convenient to place the pad on the base and improving the practicality of the voucher pressing machine.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: a voucher pressing machine for preventing deviation, including a base 1 and a limiting mechanism 6. A stand 2 is fixed above the base 1, and a pressure rod 5 is threadedly connected to the middle of the stand 2. A pressure plate 3 is connected to the lower part of the pressure rod 5 through a bearing. A guide rod 4 is fixed between the top of the base 1 and the stand 2, and the guide rod 4 is slidably connected to the four corners of the pressure plate 3.

[0020] Please see Figure 1 , Figure 2 and Figures 4-6 The limiting mechanism 6 is mounted on the base 1, and the limiting mechanism 6 includes a first bidirectional lead screw 604 and a second bidirectional lead screw 605. The first bidirectional lead screw 604 and the second bidirectional lead screw 605 are rotatably mounted in the inner cavity of the base 1 through bearings. The first bidirectional lead screw 604 and the second bidirectional lead screw 605 are arranged in a cross pattern, and the first bidirectional lead screw 604 is located above the second bidirectional lead screw 605. One end of the first bidirectional lead screw 604 and the second bidirectional lead screw 605 is fixedly connected to an adjusting handle 601. Both ends of the first bidirectional lead screw 604 and the second bidirectional lead screw 605 are threaded with sliders 602. The upper part of the sliders 602 is connected to a limiting plate 603 through a support mechanism 8, and the limiting plate 603 is designed with an L-shaped structure.

[0021] In practice, existing voucher pressing machines exert significant pressure on vouchers during pressing. Since they lack a structure to limit the outer edge of the voucher, the top layer of paper is prone to shifting, reducing the machine's performance. In this invention, before pressing, the position of the limiting plates 603 can be adjusted according to the voucher's size. Rotating the two adjusting handles 601 causes the first and second bidirectional lead screws 604 and 605 to rotate. Through the threaded engagement between the sliders 602 and the first and second bidirectional lead screws 604 and 605, the sliders 602 at both ends of the first and second bidirectional lead screws 604 and 605 move closer or further apart. Simultaneously, the sliders 602 move the limiting plates 603 closer or further apart, thus placing the four limiting plates 603 against the four corners of the voucher. This provides clamping and limiting of the voucher, allowing for pre-pressing alignment and facilitating the pressing of vouchers of different sizes.

[0022] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 The support mechanism 8 includes a fixed rod 803, which is installed above the slider 602. A telescopic rod 801 is slidably sleeved inside the fixed rod 803. A support spring 802 is installed between the lower end of the telescopic rod 801 and the bottom inside the fixed rod 803, and the top end of the telescopic rod 801 is connected to the limiting plate 603.

[0023] In practice, since the pressure plate 3 needs to apply downward pressure, the bottom surface of the pressure plate 3 will contact the limiting plate 603. When the pressure plate 3 presses, the pressure plate 3 squeezes the limiting plate 603, and the limiting plate 603 then squeezes the telescopic rod 801, causing the telescopic rod 801 to squeeze the support spring 802 downward, causing the support spring 802 to contract, thereby driving the limiting plate 603 to move downward. This can limit the document without affecting the pressing work, effectively preventing the top layer of the document from shifting and improving the working quality of the document pressing machine.

[0024] Please see Figures 1-3 The base 1 is also provided with an adjustment groove 10 for the fixed rod 803 to slide. Each adjustment groove 10 on the base 1 has several docking holes 9 on its outer side. The base 1 is also provided with a pad 7. The four corners of the pad 7 are connected with docking blocks 11 that are inserted and matched with the docking holes 9.

[0025] In practical implementation, to prevent the adjusting groove 10 from causing indentations at the bottom of the voucher, the pad 7 can be placed on the surface of the base 1 after adjusting the position of the limiting plate 603, and the mating block 11 can be inserted into the corresponding mating hole 9 to prevent the pad 7 from sliding. By setting several mating holes 9, the size of the pad 7 can be customized according to vouchers of different sizes, making it convenient to place the pad 7 on the base 1 and improving the practicality of the voucher pressing machine.

[0026] Working principle: When using this anti-offset voucher pressing machine, firstly, the size of the pad 7 is customized according to the size of the voucher. Through the cooperation of the docking hole 9 and the docking block 11, the pad 7 is placed on the surface of the base 1. Then, the voucher is placed on the pad 7. The four corners of the voucher are limited and clamped by the limiting mechanism 6. Then, the pressure rod 5 is rotated, causing the pressure rod 5 to push the pressure plate 3 downward. At the same time, the four corners of the pressure plate 3 slide downward on the outside of the guide rod 4. The pressure plate 3 squeezes the voucher and presses it. The support mechanism 8 can prevent the top layer of the voucher from shifting without hindering the pressing, thus improving the working quality and practicality of the voucher pressing machine.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
