[0014] In a further technical solution, the swing mechanism includes a slider, a rotating seat, a rotating sleeve, a connecting rod, and an abutment assembly;
[0015] The slider is slidably connected to the guide rail, the rotating seat is rotatably connected to the slider, the rotating sleeve is rotatably connected to the bracket, one end of the connecting rod is rotatably connected to the rotating seat, and the connecting rod is rotatably connected to the rotating sleeve.

[0018] In a further technical solution, the drive component includes a motor and a cam, the motor is fixedly connected to the bracket, the cam is fixedly connected to the output shaft of the motor, and the cam abuts against the disc.
[0019] A further technical solution is that the feeding mechanism includes a material box, a threaded rod, a one-way air inlet valve, and a rubber sleeve;
[0020] The material box is slidably connected to the bracket, the bracket is fixedly connected to an end seat, the threaded rod is threadedly connected to the end seat, and the threaded rod is rotatably connected to the material box. The one-way air inlet valve is installed on the material box, the rubber sleeve is sealed to the material box, and the rubber sleeve can abut against the abutting component.
[0021] In a further technical solution, the stamping assembly includes a fixing rod and a stamp.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0026] The present invention provides a quick stamping device for financial accounting. In use, the document is placed under the stamping component. The motor drives the cam to rotate, the cam pushes the disc, the disc drives the connecting rod to swing, the connecting rod drives the slider to slide in the guide rail, and at the same time the guide rail drives the stamp to move vertically through the fixed rod to stamp.
[0027] The present invention provides a quick stamping device for financial accounting. When the fixed rod moves vertically, the horizontal rod pushes the elastic telescopic rod to rotate, and the elastic telescopic rod drives the pressure roller to roll and flatten the document.
[0028] The present invention provides a quick stamping device for financial accounting. When the cam rotates, it intermittently squeezes the rubber sleeve, which increases the air pressure in the material box. As a result, the pigment in the material box is replenished to the stamp through the hose, thereby ensuring that the stamping components have sufficient pigment and ensuring the clarity of the stamp.
[0029] This invention provides a quick stamping device for financial accounting. After stamping, a spring pushes a guide rail, which in turn drives the stamp to reset via a fixed rod. By manually rotating a limiting cylinder, the limiting cylinder pushes a spring to extend or retract, thereby changing the elastic thrust of the spring on the guide rail and thus changing the vertical impact force when the fixed rod moves downward, thereby adjusting the clarity of the stamp when stamping documents.
[0030] The present invention provides a quick stamping device for financial accounting. A rotating connecting rod is threadedly driven to a fixed block. The fixed block drives a disc to move along the connecting rod, thereby changing the relative distance between the disc and the drive component, thus changing the swing amplitude of the connecting rod, thereby changing the descent height of the stamping component, and thus changing the stamping force of the stamping component on the document.
[0031] This invention provides a quick stamping device for financial accounting. When the horizontal bar moves vertically downward with the fixed bar, the horizontal bar drives the fan blades to rotate through the rotating shaft. The fan blades blow away dust and impurities from the document, ensuring the cleanliness of the document during stamping. After stamping, the horizontal bar drives the fan blades to rotate in the opposite direction through the rotating shaft, thereby drying the stamp. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0039] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0040] like Figures 1-5 As shown, a quick stamping device for financial accounting provided by the present invention includes a housing 1, and further includes:
[0041] Stamping component 2 is disposed in the outer casing 1, and stamping component 2 performs stamping by vertical movement;
[0042] An elastic support mechanism 8 is connected between the outer shell 1 and the stamping assembly 2. The elastic support mechanism 8 can provide elastic support to the stamping assembly 2, and the elastic support mechanism 8 can change its own elastic thrust.
[0043] The outer casing 1 is fixedly connected to a bracket 3, and the bracket 3 is connected to a thrust mechanism 4, the thrust mechanism 4 comprising:
[0044] The oscillating mechanism 41 is fixedly connected to the guide rail 5 of the stamping component 2. The oscillating mechanism 41 is slidably connected to the guide rail 5. While the oscillating mechanism 41 oscillates back and forth, it slides relative to the guide rail 5. At the same time, the oscillating mechanism 41 pushes the stamping component 2 to move back and forth vertically.
[0045] The drive component 42 is connected to the swing mechanism 41 by transmission, and the drive component 42 drives the swing mechanism 41 to swing back and forth by continuous rotation;
[0046] The feeding mechanism 6 is connected to the stamping component 2 by a hose 7. Under the push of the drive component 42, the feeding mechanism 6 intermittently feeds material to the stamping component 2 through the hose 7.
[0047] The leveling mechanism 9 is rotatably connected to the inner end face of the outer shell 1. When the stamping assembly 2 moves vertically, the leveling mechanism 9 can roll and level the paper surface.
[0048] When in use, the document is placed under the stamping component 2, and the drive component 42 pushes the swing mechanism 41 to swing downward by continuously rotating. The swing mechanism 41 pushes the stamping component 2 to move vertically downward. At this time, the flattening mechanism 9 rolls and flattens the paper surface, and then the stamping component 2 presses and stamps the document.
[0049] Driven by the drive component 42, the feeding mechanism 6 intermittently feeds material to the stamping component 2 through the hose 7, thereby ensuring that the stamping component 2 has sufficient ink and ensuring the clarity of the stamp.
[0050] After the stamping is completed, the stamping component 2 is reset under the elastic force of the elastic support mechanism 8, and the stamped document is taken out. Then, a new document is placed on the underside of the stamping component 2, and the drive component 4 is driven to rotate continuously to repeat the above steps.
[0051] In embodiments of the present invention, such as Figure 3 As shown, in a preferred embodiment of the present invention, the swing mechanism 41 includes a slider 411, a rotating seat 412, a rotating sleeve 413, a connecting rod 414, and an abutment assembly 415.
[0052] The slider 411 is slidably connected to the guide rail 5, the rotating seat 412 is rotatably connected to the slider 411, the rotating sleeve 413 is rotatably connected to the bracket 3, one end of the connecting rod 414 is rotatably connected to the rotating seat 412, and the connecting rod 414 is rotatably connected to the rotating sleeve 413.
[0053] The connecting rod 414 is threadedly connected to the abutment component 415, and the abutment component 415 abuts against the drive component 42;
[0054] The drive component 42 drives the connecting rod 414 to swing through the abutment component 415. The connecting rod 414 drives the slider 411 to slide in the guide rail 5. At the same time, the guide rail 5 drives the stamping component 2 to move vertically downward.
[0055] In embodiments of the present invention, such as Figure 3 As shown, in a preferred embodiment of the present invention, the abutting component 415 includes a fixing block 416 and a disc 417. The fixing block 416 is threadedly connected to the connecting rod 414, and the fixing block 416 is fixedly connected to the disc 417. The disc 417 abuts against the driving component 42.
[0056] Rotating the connecting rod 414 causes the connecting rod 414 to be threadedly driven by the fixed block 416. The fixed block 416 drives the disc 417 to move along the connecting rod 414, thereby changing the relative distance between the disc 417 and the drive assembly 42, thus changing the swing amplitude of the connecting rod 414, thereby changing the descent height of the stamping assembly 2, and thus changing the stamping force of the stamping assembly 2 on the document.
[0057] In embodiments of the present invention, such as Figure 1 As shown, in a preferred embodiment of the present invention, the drive assembly 42 includes a motor 421 and a cam 422. The motor 421 is fixedly connected to the bracket 3, and the cam 422 is fixedly connected to the output shaft of the motor 421. The cam 422 abuts against the disk 417. The motor 421 drives the cam 422 to rotate, the cam 422 pushes the disk 417, and the disk 417 drives the connecting rod 414 to swing.
[0058] In embodiments of the present invention, such as Figure 1 As shown, in a preferred embodiment of the present invention, the feeding mechanism 6 includes a material box 61, a threaded rod 62, a one-way air inlet valve 63, and a rubber sleeve 64.
[0059] The material box 61 is slidably connected to the bracket 3, the bracket 3 is fixedly connected to the end seat 10, the threaded rod 62 is threadedly connected to the end seat 10, and the threaded rod 62 is rotatably connected to the material box 61. The one-way air inlet valve 63 is provided on the material box 61, the rubber sleeve 64 is sealed to the material box 61, and the rubber sleeve 64 can abut against the abutting component 415.
[0060] When the cam 422 rotates, it intermittently squeezes the rubber sleeve 64, increasing the air pressure in the material box 61. As a result, the pigment in the material box 61 is replenished onto the stamp 22 through the hose 7. After that, the air pressure in the material box 61 decreases, and external air enters the material box 61 through the one-way air inlet valve 63.
[0061] In embodiments of the present invention, such as Figure 2 and Figure 4As shown, in a preferred embodiment of the present invention, the stamping assembly 2 includes a fixing rod 21 and a stamp 22. One end of the fixing rod 21 is fixedly connected to the stamp 22, and the other end of the fixing rod 21 is fixedly connected to the guide rail 5. The fixing rod 21 is slidably connected to the elastic support mechanism 8. The fixing rod 21 is hollow inside, and the material box 61 is connected to the fixing rod 21 through a flexible hose 7. The fixing rod 21 drives the stamp 22 to move vertically to stamp.
[0062] In embodiments of the present invention, such as Figure 4 As shown, in a preferred embodiment of the present invention, the elastic support mechanism 8 includes a sleeve 81, a limiting sleeve 82 and a spring 83. The sleeve 81 is fixedly connected to the outer shell 1, the limiting sleeve 82 is threadedly connected to the sleeve 81, and the spring 83 is sleeved on the outside of the fixed rod 21 and abuts against the limiting sleeve 82.
[0063] Spring 83 pushes guide rail 5, and guide rail 5 drives stamp 22 to reset via fixing rod 21; by manually rotating limiting cylinder 82, limiting cylinder 82 pushes spring 83 to extend and retract, thereby changing the elastic thrust of spring 83 on guide rail 5, thereby changing the vertical impact force of fixing rod 21 when it moves downward, thus adjusting the clarity of stamping when stamping documents.
[0064] In embodiments of the present invention, such as Figure 2 and Figure 5 As shown, in a preferred embodiment of the present invention, the leveling mechanism 9 includes an elastic telescopic rod 91, an elastic torsion spring 92, and a pressure roller 93. One end of the elastic telescopic rod 91 is rotatably connected to the inner end face of the outer shell 1 through the elastic torsion spring 92, and the pressure roller 93 is rotatably connected to one end of the elastic telescopic rod 91. The fixed rod 21 is fixedly connected to a crossbar 94, and the crossbar 94 abuts against the elastic telescopic rod 91.
[0065] When the fixed rod 21 moves vertically, the horizontal bar 94 pushes the elastic telescopic rod 91 to rotate, and the elastic telescopic rod 91 drives the pressure roller 93 to roll and flatten the document.
[0066] In embodiments of the present invention, such as Figure 2 As shown, in a preferred embodiment of the present invention, the inner end face of the outer shell 1 is rotatably connected to a rotating shaft 11, the rotating shaft 11 is fixedly connected to a fan blade 12, the outer side of the rotating shaft 11 is provided with a spiral track, the rotating shaft 11 is connected through the crossbar 94, and the spiral track on the rotating shaft 11 meshes with the spiral guide rail on the crossbar 94.
[0067] When the horizontal bar 94 moves vertically downward with the fixed bar 21, the horizontal bar 94 drives the fan blade 12 to rotate through the rotating shaft 11. The fan blade 12 blows away dust and impurities from the document, ensuring the cleanliness of the document during stamping. After stamping, the horizontal bar 94 drives the fan blade 12 to rotate in the opposite direction through the rotating shaft 11, thereby drying the stamp.
[0068] When in use, the document is placed under the stamping component 2. The motor 421 drives the cam 422 to rotate. The cam 422 pushes the disc 417. The disc 417 drives the connecting rod 414 to swing. The connecting rod 414 drives the slider 411 to slide in the guide rail 5. At the same time, the guide rail 5 drives the stamp 22 to move vertically through the fixed rod 21 to stamp.
[0069] At the same time, when the fixed rod 21 moves vertically, the horizontal bar 94 pushes the elastic telescopic rod 91 to rotate, and the elastic telescopic rod 91 drives the pressure roller 93 to roll and flatten the document;
[0070] When the cam 422 rotates, it intermittently squeezes the rubber sleeve 64, increasing the air pressure in the material box 61. This allows the pigment in the material box 61 to be replenished onto the stamp 22 through the hose 7, ensuring that the stamping components 2 have sufficient pigment and guaranteeing the clarity of the stamp. Afterward, the air pressure in the material box 61 decreases, and external air enters the material box 61 through the one-way air inlet valve 63 to maintain the air pressure balance inside the material box 61.
[0071] After the stamping is completed, the guide rail 5 is pushed by the spring 83, and the guide rail 5 drives the stamp 22 to reset through the fixing rod 21; the limiting cylinder 82 is rotated by hand, and the limiting cylinder 82 pushes the spring 83 to extend and retract, thereby changing the elastic thrust of the spring 83 on the guide rail 5, thereby changing the vertical impact force of the fixing rod 21 when it moves downward, thereby adjusting the clarity of the stamp when the document is stamped.
[0072] Afterwards, take out the stamped document, then place the new document under the stamping component 2, and drive component 4 to rotate continuously to repeat the above steps;
[0073] Rotating the connecting rod 414 causes the connecting rod 414 to be threadedly driven by the fixed block 416. The fixed block 416 drives the disc 417 to move along the connecting rod 414, thereby changing the relative distance between the disc 417 and the drive assembly 42, thus changing the swing amplitude of the connecting rod 414, thereby changing the descent height of the stamping assembly 2, and thus changing the stamping force of the stamping assembly 2 on the document.
[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
