[0002] A document is a written proof obtained or filled out when an economic transaction occurs, which records the actual situation of the transaction or matter. It is the original data and important basis for accounting. When accountants are working, they sometimes print accounting documents on paper for filing. However, sometimes multiple documents are printed on one piece of paper or there is a lot of blank paper around the document. At this time, a document cutting device is needed to cut the document.

[0003] In the existing accounting document cutting device, when cutting accounting documents, the operator generally arranges and aligns the documents and stacks them into several piles, then places the stacked documents on the base of the cutting device, manually adjusts the position of the documents, and finally rotates the cutter to cut the accounting documents through the mutual interference among the documents, the cutter and the base. The operation is troublesome, and the movement of the stacked accounting documents and the mutual interference between the accounting documents and the cutter may cause the stacked documents to tilt and misalign, affecting the cutting of the documents. At the same time, since the cutting device is limited in the number of documents that can be cut at one time, the documents need to be divided into multiple parts for cutting, which reduces the operator's work efficiency.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The utility model provides a technical solution: Figure 1-5The utility model discloses an accounting document cutting device, comprising a storage box 1 for storing accounting documents, a feeding mechanism 2 is arranged in the storage box 1, a cutting mechanism 3 is arranged at the bottom end of the storage box 1, and the cutting mechanism 3 comprises two support plates 31 arranged in an L-shape, the two support plates 31 are relatively fixedly mounted at the bottom end of the storage box 1, a rotating shaft 32 and a round rod 33 are arranged between the two support plates 31 from top to bottom, and the rotating shaft 32 and the round rod 33 are located outside the storage box 1, the two ends of the rotating shaft 32 and the round rod 33 respectively penetrate the two support plates 31 and are rotatably connected to the two support plates 31 through bearings, a cutting knife 34 arranged in an annular shape is sleeved on the outer peripheral side of the rotating shaft 32, and the cutting knife 34 is connected to the rotating shaft 32 through a connecting piece 36.

[0023] In this embodiment, when the improved cutting device is cutting accounting documents, the operator can stack all the accounting documents together and stuff the stacked accounting documents into the storage box 1, and then the feeding mechanism 2 pushes the accounting documents at the bottom into the gap between the round rod 33 and the rotating shaft 32 in turn, and at the same time, the accounting documents are rolled and cut by the cooperation of the cutter 34 and the roller to divide the cutter 34 into two parts, and the operator does not need to perform other operations. At the same time, in the process of cutting the accounting documents, the accounting documents can be constrained and limited synchronously, so that in the process of cutting the accounting documents, there is almost no situation where the accounting documents are tilted or misaligned to affect the cutting of the accounting documents.

[0024] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the feeding mechanism 2 includes a rectangular hole 21, a clearance fit between the rotating shaft 32 and the round rod 33, and the rectangular hole 21 is opened at the bottom end of the storage box 1 at a position corresponding to the gap between the rotating shaft 32 and the round rod 33;

[0025] In this embodiment, the above-mentioned feeding mechanism 2 pushes the accounting documents at the bottom to move out of the storage box 1 through the rectangular hole 21, and the remaining accounting documents will not move with the bottom accounting documents due to the interception of the inner wall of the storage box 1, so that the feeding mechanism 2 can push the stacked accounting documents out of the storage box 1 one by one.

[0026] In a further preferred embodiment of the present invention, Figure 1 and Figure 4 As shown, the blade of the cutter 34 is connected to the outer peripheral wall of the round rod 33, and the outer peripheral sides of both ends of the rotating shaft 32 are fixedly sleeved with soft sleeves 35, and each soft sleeve 35 is located between the cutter 34 and the corresponding support plate 31, and the outer peripheral wall of the soft sleeve 35 is connected to the outer peripheral wall of the round rod 33;

[0027] In this embodiment, during the process of inserting the above-mentioned accounting document into the gap between the rotating shaft 32 and the round rod 33, due to the mutual interference between the soft sleeve 35 and the accounting document, the sleeve wall of the soft sleeve 35 shrinks and deforms, so that the accounting document can be inserted between the soft sleeve 35 and the round rod 33. After the accounting document is inserted between the round rod 33 and the soft sleeve 35, due to the reset deformation of the soft sleeve 35, the soft sleeve 35 and the round rod 33 clamp and limit the accounting document from both sides of the accounting document, so that the accounting document will not be offset when the cutter 34 is rolling and cutting the accounting document.

[0028] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the connecting member 36 includes a plurality of knobs 362, a sleeve 361 is fixedly provided in the cutter 34, and the inner peripheral wall of the sleeve 361 contacts the outer peripheral wall of the rotating shaft 32, and the plurality of knobs 362 are arranged on both sides of the cutter 34, and each knob 362 is threadedly passed through the wall of the sleeve 361 and contacts the outer peripheral wall of the rotating shaft 32;

[0029] In this embodiment, the operator turns the knob 362 to separate the knob 362 from the rotating shaft 32, thereby releasing the locked state between the cutter 34 and the rotating shaft 32. The operator then pushes the cutter 34. Due to the mutual interference between the sleeve 361 and the rotating shaft 32, the cutter 34 moves along a linear trajectory along the rotating shaft 32, so that the position of the cutter 34 can be adjusted according to the cutting position of the accounting document. After the position adjustment of the cutter 34 is completed, the operator turns the knob 362 to cause the knob 362 to interfere with the outer peripheral wall of the rotating shaft 32. At this time, due to the mutual interference between the knob 362 and the sleeve 361, a restraining force can be applied to the cutter 34 through the friction between the knob 362 and the rotating shaft 32, thereby locking the position between the cutter 34 and the rotating shaft 32.

[0030] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a belt 22 is provided in the bottom opening of the storage box 1, one end of the belt 22 and the two side walls of the belt 22 are in contact with the inner wall of the storage box 1, and the other end of the belt 22 passes through the rectangular hole 21, the top side of the belt 22 is gap-matched with the inner top wall of the rectangular hole 21, and the outer peripheral wall of the round rod 33 is connected with the outer peripheral wall of the belt 22, two driving rollers 23 are oppositely provided in the belt 22, and the outer peripheral wall of the driving roller 23 is interference-fitted with the inner ring wall of the belt 22, both ends of the driving roller 23 pass through the corresponding support plate 31 and are rotatably connected to the corresponding support plate 31, a driver 4 is fixedly installed on the side of the support plate 31 away from the storage box 1, and a plurality of driving ends of the driver 4 are respectively fixedly connected to the rotating shaft 32, the round rod 33 and the two driving rollers 23;

[0031] In this embodiment, the driver 4 is started, driving the rotating shaft 32, the round rod 33 and the driving roller 23 to rotate synchronously, and the rotating driving roller 23 drives the belt 22 to move along a fixed track, and due to the friction between the belt 22 and the bottom accounting document, the bottom accounting document moves toward the rectangular hole 21, while the remaining accounting documents will not move with the bottom accounting document due to the interception of the inner wall of the storage box 1. The moving accounting documents gradually pass through the rectangular hole 21 and move into the gap between the rotating shaft 32 and the round rod 33. After the first accounting document is pushed out of the rectangular hole 21, the accounting document moves downward due to its own gravity, so that the bottom accounting document is re-fitted with the belt 22.

[0032] In a further preferred embodiment of the present invention, Figure 3 As shown, a limit plate 24 is provided between the belt 22 and the rotating shaft 32, and both ends of the limit plate 24 are fixedly connected to the two support plates 31 respectively, the top side of the limit plate 24 is coplanar with the top side of the belt 22 and the top side of the round rod 33, one side of the limit plate 24 is in contact with the outer peripheral wall of the belt 22, and the other side of the limit plate 24 is inserted between the rotating shaft 32 and the round rod 33 and contacts with the outer peripheral wall of the round rod 33;

[0033] In this embodiment, when the accounting document is removed from the belt 22, it will move directly to the top of the limit plate 24, and the accounting document will not be bent or deformed due to its own gravity, thereby affecting the insertion of the accounting document into the round rod 33 and the rotation of the shaft 32.

[0034] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, a pressing plate 25 is provided in the storage box 1, and the outer peripheral wall of the pressing plate 25 contacts the inner wall of the storage box 1, and a plurality of guide grooves 26 are relatively opened on the inner wall of the storage box 1 at positions corresponding to the pressing plate 25, and a limit block 27 is slidably installed in the guide groove 26, and a part of the limit block 27 extends to the outside of the corresponding guide groove 26 and is fixedly connected to the pressing plate 25;

[0035] In this embodiment, after the stacked documents are inserted into the storage box 1, the stacked documents are stacked together in a specific state due to the mutual interference between the stacked documents and the inner wall of the storage box 1. Then the pressure plate 25 is released and moves downward due to the action of its own gravity to press on the stacked documents, so that the accounting documents are in a flat state and fit together tightly, preventing the accounting documents from tilting up and being unable to slide out of the rectangular hole 21.

[0036] Working principle: When cutting accounting documents, the operator arranges and stacks all accounting documents together, then holds the stacked documents in one hand and pulls up the pressing plate 25 with the other hand, and inserts the stacked documents into the storage box 1. Due to the mutual interference between the stacked documents and the inner wall of the storage box 1, the stacked documents are stacked together in a specific state, and then the pressing plate 25 is released. Due to the effect of its own gravity, the pressing plate 25 moves downward and presses on the stacked documents, so that the accounting documents are in a flat state and fit together tightly;

[0037] It should be noted that, during the movement of the pressing plate 25 in the storage box 1, due to the mutual interference between the stop block 27 and the inner wall of the guide groove 26, the pressing plate 25 moves in a linear track in the up-and-down direction in the storage box 1;

[0038] After the accounting document is loaded, the operator turns the knob 362 to separate the knob 362 from the rotating shaft 32, thereby releasing the limit state of the cutter 34, and then the operator pushes the cutter 34. Due to the mutual interference between the sleeve 361 and the rotating shaft 32, the cutter 34 moves along the rotating shaft 32 in a linear trajectory, so that the position of the cutter 34 can be adjusted according to the cutting position of the accounting document. After the position adjustment of the cutter 34 is completed, the operator turns the knob 362 to make the knob 362 and the outer peripheral wall of the rotating shaft 32 conflict with each other. At this time, due to the mutual interference between the knob 362 and the sleeve 361, a restraining force can be applied to the cutter 34 through the friction between the knob 362 and the rotating shaft 32, thereby locking the position between the cutter 34 and the rotating shaft 32;

[0039] Then the driver 4 starts, driving the rotating shaft 32, the round rod 33 and the driving roller 23 to rotate synchronously, and the rotating driving roller 23 drives the belt 22 to move along a fixed track, and due to the friction between the belt 22 and the bottom accounting document, the bottom accounting document moves toward the rectangular hole 21, while the remaining accounting documents will not move with the bottom accounting document due to the interception of the inner wall of the storage box 1, and the moving accounting documents gradually pass through the rectangular hole 21 and move into the gap between the rotating shaft 32 and the round rod 33;

[0040] It should be noted that when the accounting document is removed from the belt 22, it will directly move to the top of the limit plate 24, and the accounting document will not be bent and deformed due to its own gravity, which will affect the insertion of the accounting document into the round rod 33 and the rotation of the shaft 32;

[0041] After the accounting document is removed from the limiting plate 24, it is directly inserted between the soft sleeve 35 and the round rod 33. At this time, due to the mutual interference between the soft sleeve 35 and the accounting document, the soft sleeve 35 shrinks and deforms to leave space between the soft sleeve 35 and the round rod 33 for the accounting document to be inserted, and finally the accounting document is directly inserted between the soft sleeve 35 and the round rod 33. With the rotation of the shaft 32 and the round rod 33, the accounting document gradually passes through the gap between the shaft 32 and the round rod 33.

[0042] It should be noted that after the accounting document is inserted between the soft sleeve 35 and the round rod 33, the soft sleeve 35 is deformed and reset, and the soft sleeve 35 and the round rod 33 clamp the accounting document from both sides of the accounting document, so that a great friction force is generated between the accounting document and the outer peripheral wall of the soft sleeve 35 and the outer peripheral wall of the round rod 33;

[0043] When the accounting document passes through the gap between the round rod 33 and the soft sleeve 35, the cutter 34 cooperates with the round rod 33 to roll and cut the accounting document, thereby cutting the accounting document into two parts. According to the above-mentioned belt 22, the accounting document is pushed between the rotating shaft 32 and the round rod 33 at one time, and the cutter 34 gradually completes the cutting process of the accounting document.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
