Description

Technical Field

[0001] This utility model relates to the field of office equipment technology, and more specifically, to a punching device for accounting vouchers. Background Technology

[0002] Accounting vouchers are written documents that record the occurrence or completion of economic transactions. They serve as the basis for bookkeeping. Every enterprise must prepare and verify accounting vouchers according to certain procedures, and make book entries based on the verified accounting vouchers to accurately reflect the enterprise's economic transactions. Classified by preparation procedure and purpose, accounting vouchers are divided into original vouchers and journal vouchers. The former, also known as documents, are original written documents prepared at the initial occurrence of an economic transaction, such as sales invoices and receipts. The latter, also known as journal vouchers, are accounting vouchers prepared based on verified original vouchers, categorized according to the content of the economic transaction, and used to determine the accounting entries. They are the direct basis for bookkeeping. Commonly used journal vouchers include receipts, payment vouchers, and transfer vouchers. Regardless of the type, accounting vouchers need to be properly preserved. To ensure the integrity of the preserved accounting vouchers, they are generally punched and bound.

[0003] For example, Chinese utility model patent CN210189999U discloses a rotary manual punching machine, including a punching plate, a support base, a push groove, a spiral groove, a gear groove, a rack, a top ball, a punching device, a gear, and a handle. An L-shaped support base is vertically fixed to the top surface of the punching plate. A vertical push groove is formed on the front side of the top of the support base. A spiral groove is provided at the bottom of the push groove. A gear groove is connected to the right side of the push groove. The rack slides up and down within the push groove. A top ball is integrally formed at the bottom of the rack. A punching device is located below the rack within the push groove. The gear is located within the gear groove and meshes with the rack. The handle is connected to the center key of the gear. The machine uses manual rotation of the handle to move the punching needle up and down and rotate to punch holes in paper. However, during the punching process, the paper is prone to displacement, leading to deviations in the drilling position and ultimately affecting the binding operation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a punching device for accounting vouchers.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0029] See attached document Figures 1 to 7 This utility model provides a more detailed description of a punching device for accounting vouchers.

[0030] A punching device for accounting vouchers includes a base 1, on which a clamping mechanism 2 for clamping accounting vouchers and a punching mechanism 3 for punching holes in accounting vouchers are provided, with the punching mechanism 3 positioned above the clamping mechanism 2.

[0031] The clamping mechanism 2 includes a base plate 21. A backing plate 22 is vertically arranged at one end of the base plate 21, and a clamping assembly 23 is arranged at the other end. The clamping assembly 23 includes a clamping plate 231 slidably arranged on the base plate 21 and a clamping spring 232. One end of the clamping spring 232 abuts against the base plate 21, and the other end abuts against the clamping plate 231. The clamping spring 232 causes the clamping plate 231 to cooperate with the backing plate 22 to clamp the accounting documents on the base plate 21.

[0032] The drilling mechanism 3 includes a support frame 31 fixed on the base 1, a clamping cylinder 32 installed on the support frame 31, a clamping plate 34 placed below the support frame 31, and a drilling assembly 33.

[0033] The punching assembly 33 includes a punching motor 331 equipped with a punching needle 3311 and a mounting assembly 332. The mounting assembly 332 includes a mounting plate 3321, a sliding rod 3322 fixed above a pressure plate 34, and a compression spring 3323 sleeved on the sliding rod 3322. The mounting plate 3321 is vertically slidably disposed on the upper end of the sliding rod 3322. The lower end of the compression spring 3323 abuts against the pressure plate 34, and its upper end abuts against the mounting plate 3321.

[0034] The telescopic rod of the clamping cylinder passes through the support frame 31 and is connected to the mounting plate 3321. The clamping cylinder drives the clamping plate 34 to move downward with the punching assembly 33 by pressing down the mounting plate 3321. The clamping plate 34 presses down on the accounting voucher on the base plate 21. The punching needle 3311 passes through the perforation 342 on the clamping plate 34 and punches the accounting voucher under the drive of the punching motor 331.

[0035] When punching accounting vouchers, the accounting voucher to be punched is placed on the base plate 21. The clamping plate 231 at one end of the base plate 21 moves toward the abutment plate 22 under the action of the clamping spring 232 and cooperates with the abutment plate 22 to clamp the accounting voucher on the base plate 21 and position the accounting voucher.

[0036] The clamping cylinder 32 drives the mounting plate 3321 to move downwards. The mounting plate 3321 compresses the compression spring 3323 and drives the clamping plate 34 to move downwards, so that the clamping plate 34 presses the accounting voucher downwards. The clamping cylinder 32 continues to press down the mounting plate 3321 and continues to compress the compression spring 3323, so that the punching needle 3311 passes through the through hole 342. The punching needle 3311 then punches a hole in the accounting voucher under the drive of the punching motor 331. The clamping mechanism 2 clamps and positions the accounting voucher on the base plate 21. Before the punching needle 3311 punches the accounting voucher, the clamping plate 34 first presses down on the punching end of the accounting voucher. This avoids displacement of stacked accounting vouchers during the punching process, ensures the accuracy of the drilling position of the accounting voucher, and enables the accounting voucher to be better bound.

[0037] The base plate 21 is provided with a sliding groove 211, and the clamping plate 231 is provided with a slider 2311 adapted to the sliding groove 211; the slider 2311 slides along the sliding groove 211, driving the clamping plate 231 to slide at both ends of the base plate 21; to prevent the clamping plate 231 from shifting during the back-and-forth sliding process, so that the clamping plate 231 can better cooperate with the abutment plate 22 to clamp and position the accounting documents.

[0038] The clamping plate 231 is connected to a mounting rod 233 for mounting a clamping spring 232. The front end of the base plate 21 is provided with a mounting groove 212 that matches the mounting rod 233. The rear end of the clamping spring 232 abuts against the mounting rod 233, and the front end abuts against the groove wall of the mounting groove 212. The clamping plate 231 and the mounting rod 233 are connected by a connecting plate 234. The front end of the connecting plate 234 is provided with a handle 2341. When placing the accounting voucher to be punched, pull the handle 2341 outward to make the clamping plate 231 slide forward and compress the clamping spring 232. After releasing the handle 2341, the clamping spring 232 pushes the clamping plate 231 backward through the mounting rod 233, so that the clamping plate 231 cooperates with the base plate to clamp the accounting voucher; thus positioning the accounting voucher.

[0039] The clamping plate 34 is connected to two guide rods 341 at both ends. The support frame 31 is provided with two guide holes 311 that are adapted to the guide rods 341. The upper end of the guide rod 341 passes through the guide hole 311. The clamping plate 34 moves up and down under the guidance of the guide rods 341, so that the clamping plate 34 can move more smoothly and avoid tilting, thereby enabling the clamping plate 34 to better press the accounting voucher downward.

[0040] The number of punching motors 331 is two, and the two punching motors 331 are respectively installed on the two ends of the mounting plate 3321; so that the two punching motors 331 can perform punching operations on accounting documents simultaneously, thereby improving punching efficiency.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
