Embodiment 1

[0029] refer to Figure 1-4, a punching machine for document binding, comprising an installation box 1 and a heating jacket 106, the heating jacket 106 is fixedly connected to the installation box 1, and is characterized in that an installation cavity 101 is provided in the installation box 1, and the bottom wall of the installation cavity 101 is formed by From left to right, guide sleeves 105 and rotating seats 104 are fixedly connected in sequence. The number of guide sleeves 105 is specifically divided into two groups. The two sets of guide sleeves 105 are respectively slidingly connected with perforating nails 401 and melting nails 1061. The melting nails 1061 run through the heating sleeve 106. , the punching nail 401 and the melting nail 1061 are fixedly connected to the first positioning shaft 4011, the rotating base 104 is connected to the first rotating shaft 2 and the second rotating shaft 3, and the first rotating shaft 2 and the second rotating shaft 3 are fixedly c...

Embodiment 2

[0031] refer to figure 1 and Figure 5 , is basically the same as in Embodiment 1, furthermore, the flattening mechanism includes a base plate 403 and a telescopic plate 404, the base plate 403 is fixedly connected to the punching nail 401, and the telescopic plate 404 is fixedly connected to a telescopic column 4041, and the telescopic column 4041 slides Connected to the base plate 403, the telescopic column 4041 is sleeved with a spring 405, and the two ends of the spring 405 are respectively against the base plate 403 and the telescopic plate 404, and the end of the telescopic column 4041 away from the telescopic plate 404 is fixedly connected to the limit ring 4042, the limit ring 4042 is attached to the top of the base plate 403. During the pressing process of the perforated nail 401, the telescopic plate 404 first contacts the surface of the file, thereby flattening the surface of the file. During the continuous pressing of the perforated nail 401, the telescopic column ...

Embodiment 3

[0033] refer to Figure 1-2 , is basically the same as Embodiment 1, furthermore, the base 102 can be fixedly connected to the bottom of the installation box 1, and the base 102 and the installation box 1 are integrally formed, and the base 102 is provided with a through hole 1021, and the installation box 1 There is a first guide groove 103 on the top, and the pressure handle 4 is slidably connected in the first guide groove 103. The rubber sleeve 4013 is arranged on the pressure handle 4, and the second guide groove 1051 is opened on the guide sleeve 105, and the first positioning shaft 4011 slides Connected in the second guide groove 1051, the through hole 1021 on the abutment 102 can make the punctured archival scraps fall directly on the bottom of the abutment 102 for easy collection, and the two groups correspond to the punching nails 401 and the melting nails 1061 The through hole 1021 can make the perforated nail 401 and the fusion nail 1061 go deeper, guarantee to pun...

Abstract

The invention discloses a punching machine for file binding, and belongs to the technical field of accounting tools. The punching machine for file binding comprises a mounting box and a heating sleeve, a guide sleeve and a rotating seat are connected in a mounting cavity, a punching nail and a melting nail are glidingly connected in the guide sleeve, first positioning shafts are connected to the punching nail and the melting nail, a second positioning shaft is connected to a pressing handle, the first positioning shaft is rotationally connected with the second positioning shaft, and a flattening mechanism is arranged on the punching nail; the first rotating shaft and the second rotating shaft are connected with a first rotating ring and a second rotating ring correspondingly, a first rotating sleeve and a second rotating sleeve are connected through a torsional spring, first ratchets are arranged in the first rotating sleeve and the second rotating sleeve, a first pawl and a second pawl mesh with the first ratchets, the second pawl is connected with an arc-shaped gear, an opening and closing shaft is connected with an opening and closing gear, the opening and closing gear meshes with the arc-shaped gear, and a one-way mechanism is arranged on the rotating seat. After paper is flattened, the stability during melting is ensured by the aid of the energy storage characteristic of the torsion spring.

Description

[0001] This application is a divisional application, the original patent number is: 202010499170.4, the application date is June 4, 2020, and the title of the invention is: an accounting voucher punching device. technical field [0002] The invention relates to the technical field of accounting tools, in particular to a punching machine for document binding. Background technique [0003] Accounting file punching device refers to cutting paper to a specified shape through pins, round tube cutters and other tools under the action of local pressure. The main purpose is to better bind accounting files and text paper into books for organizing files. . [0004] In the prior art, because some accounting file punching devices cannot fix and flatten the paper when punching holes, the paper is dented under the action of pressure, causing the hole surface in the paper to bend and deform, and it cannot be bound well. After punching, you need to use a rubber sleeve to heat-melt the hole...
