Description

Technical Field

[0001] The present invention relates to the technical field of voucher punching, and in particular to a voucher punching device. Background Art

[0002] Accounting vouchers are written proofs that record economic activities and clarify economic responsibilities. They are an important basis for registering accounts and conducting accounting supervision. Accounting vouchers are filled out by accountants after classifying the original vouchers or summarized original vouchers that have been audited and found to be correct according to the content of their economic transactions and determining the accounting entries accordingly. Accounting vouchers that serve as the basis for registering accounts are also called entry vouchers or accounting vouchers. They are records that determine the account name, accounting direction and amount in accordance with the requirements of registering accounts. They are the basis for registering detailed ledgers and general ledgers. Accounting vouchers can be divided into receipt vouchers, payment vouchers and transfer vouchers according to the different contents of the economic transactions they reflect.

[0003] When storing the voucher, it is necessary to punch holes in the voucher through a punching device, and then pass a binding wire through the holes and tie them up. However, most of the current voucher punching devices directly punch holes without restricting the voucher.

[0004] 1) If the accounting voucher is not fixed during the punching process, it may be displaced under the pressure of the punching device, causing the punching position to deviate from the predetermined position, thereby affecting the binding effect of the voucher and making it inconvenient to file, review and use the voucher;

[0005] 2) Unfixed accounting vouchers are more susceptible to external impact when punching, which may cause tearing, wrinkling or damage to the edges of the vouchers, which may affect the integrity and readability of the vouchers, thereby reducing their use value;

[0006] 3) Since accounting documents may be displaced during the punching process, operators need to spend extra time and energy to readjust the position of the documents to ensure the accuracy of the punching, which will reduce the punching efficiency and increase the labor intensity of the operators. Summary of the invention

[0007] In view of the fact that the accounting voucher is not fixed during the punching operation in the above-mentioned existing device, it is easy to cause displacement under the pressure of the punching device, causing the punching position to deviate from the predetermined position, thereby affecting the binding effect of the voucher, and may also make the voucher inconvenient during filing, review and use, and may cause the edge of the voucher to tear, wrinkle or damage, which may easily affect the integrity and readability of the voucher, thereby reducing its use value, and also reduce the punching efficiency. It may also increase the labor intensity of the operator. The present invention is proposed.

[0008] Therefore, the purpose of the present invention is to provide a voucher punching device, the purpose of which is to: fix the voucher during the punching operation, improve the stability of the voucher during punching, and thereby improve the subsequent binding effect of the voucher.

The plurality of groups of guide grooves 48 and the plurality of groups of connecting holes 336 on the mounting cross plate 314 correspond to each other, and then the operator can be assisted to align the positioning socket 330 and the connecting hole 336 on the second limiting slide block 328 at the top of the main punching rod 316.

[0055] During use, after the voucher is fixed and restricted on the top of the placement table 1, the electric push rod 315 is started to drive the installation cross plate 314 to descend, which will drive the movable cross plate 43 on the L-shaped connecting rod 42 to move downward in advance, so that the pressing bottom plate 45 moves downward and contacts the top of the voucher first, and then as the installation cross plate 314 continues to move downward, the pressing bottom plate 45 will be close to the top of the voucher, and at the same time, the movable cross plate 43 slides on the surface of the movable slide rod 44 and approaches the pressing bottom plate 45, and then the second spring 46 can be compressed, and then the main punching rod 316 on the installation cross plate 314 continues to move downward to complete the punching of the voucher. After the punching is completed, the main punching rod 316 on the installation cross plate 314 first rises, and then the rebound force of the second spring 46 is used to drive the movable cross plate 43 to move up and reset, thereby driving the pressing bottom plate 45 to move up to cancel the fixation of the voucher.

[0056] The remaining structure is the same as that of Example 2.
