Description

Technical Field

[0001] The present invention relates to the technical field of paper book shredding, and in particular to a shredding device for paper voucher books. Background Art

[0002] Regarding the preservation of paper voucher books, especially accounting files, the retention period of accounting vouchers is usually 30 years. Some special accounting files, such as monthly / quarterly financial reports, are usually kept for ten years. These preserved accounting vouchers are generally paper voucher books. When the retention period expires, these paper voucher books need to be destroyed in a timely manner, such as by using a shredder. However, the destruction process usually has the following problems:

[0003] First, the paper voucher books that need to be shredded are usually multi-page books organized into volumes. These sheets are usually thick, and during the shredding process, they usually need to be manually separated and shredded multiple times. This shredding method often poses a risk of information leakage due to direct contact between personnel, and fails to achieve confidentiality. If the thick paper voucher books are not separated and are directly put into the shredder, the shredder will easily jam, resulting in incomplete shredding of the paper voucher books.

[0004] Secondly, for example, according to the Chinese patent publication number "CN202123002954.0", a patent document entitled "An Accounting Voucher Processing Device for Financial Sharing" is disclosed. The method adopted in the application document is to crush the paper first, and then use a water spray component to spray water to blur the handwriting. However, the conventional shredded paper is in strips. These shredded strips are in the shredded state, but this type of strip shreds can be easily spliced together by humans, and information leakage is very likely to occur. The ink spraying method can also remove the ink sprayed on the paper through some chemical agents, so the conventional method of crushing into strips is also very likely to cause file information leakage.

[0005] To this end, we designed a shredding device for paper voucher books. Summary of the Invention

[0047] Reference Figures 1-12 The shredder 5 is a paper shredder which is used to shred paper.

[0048] Reference Figure 2 In the exploded view of the state, the paper separation mechanism 6 is located above the paper shredder mechanism 5, so that a stack of paper vouchers to be shredded can be directly put into the paper shredder mechanism 5 for shredding after being paginated by the paper separation mechanism 6. The specific operation is as follows:

[0049] The crushing box body 1 is provided with a paper separation mechanism 6 for paging the stack of paper vouchers. The paper separation mechanism 6 is provided in multiple configurations. The paper separation mechanism 6 includes an isosceles triangle block 61. The stack of paper vouchers is separated and paginated to both sides through the top of the isosceles triangle block 61. Figure 11 As shown, when a stack of paper vouchers to be shredded touches the top of the isosceles triangle block 61 , the stack of paper vouchers to be shredded will be divided into two parts, and divided into two parts from both sides of the isosceles triangle block 61 .

[0050] Reference Figure 11 and Figure 12 In this state, the paper separation mechanism 6 also includes a conveyor belt portion 64. The conveyor belt portion 64 is set in two and is symmetrically arranged on both sides of the isosceles triangle block 61. The conveyor belt portion 64 is placed on both sides of the isosceles triangle block 61 through the installation groove. It should be noted that the conveying direction of the conveyor belt portion 64 is toward the paper guide arc plate 62 and the paper guide block 63, so that the paginated stacks of paper vouchers can be conveyed to the position between the paper guide arc plate 62 and the paper guide block 63 through the conveyor belt portion 64.

[0051] Among them, the paginated stacks of paper vouchers are conveyed on the conveyor belt portion 64. The expected effect cannot be achieved by relying solely on the conveyor belt portion 64. Therefore, another conveying method is required. Pressing rollers 65 are provided on both sides of the isosceles triangle block 61 to press toward the conveyor belt portion 64. The pressing rollers 65 are pressed toward the conveyor belt portion 64 by the return spring 69. Therefore, the pressing rollers 65 are ensured to push the paginated stacks of paper vouchers against the surface of the conveyor belt portion 64 under the action of the return spring 69, so that the paginated stacks of paper vouchers can be moved together.

[0052] The side of the conveyor belt portion 64 facing the pressing roller 65 is flush with the side of the isosceles triangle block 61, that is, the conveyor belt portion 64 and the side of the isosceles triangle block 61 are located in the same plane, thereby ensuring that the stacks of paper vouchers after paging are always in a stable state during the sliding process.

[0053] The transmission belt portion 64 includes a transmission belt and two belt rollers. The belt rollers are arranged at both ends of the transmission belt. The belt rollers rotate in the mounting groove. A first motor is arranged in the mounting groove. One of the belt rollers is connected to the output end of the first motor. Therefore, the first motor provides rotational force for the belt roller, thereby driving the transmission belt portion 64 to transmit.

[0054] A fixing plate 67 is provided at the end of the isosceles triangle block 61 , so the isosceles triangle block 61 is fixedly mounted on the inner wall of the crushing box body 1 through the fixing plate 67 .

[0055] The fixed plate 67 is parallel to the side of the isosceles triangle block 61, and a telescopic rod 68 is vertically slidable through the fixed plate 67. The pressing roller 65 rotates at the end of the telescopic rod 68 through the pillow block 66. Therefore, the pressing roller 65 rotates through the pillow block 66 and is squeezed toward the conveyor belt part 64 under the action of the telescopic rod 68. An external drive motor is provided on the pillow block 66, and the output end of the external drive motor is coaxially connected to the pressing roller 65 to provide driving force for the rotation of the pressing roller 65. The transmission of the pressing roller 65 and the conveyor belt part 64 both drives the paginated stacks of paper vouchers to be squeezed and conveyed together, so that the paginated stacks of paper vouchers move toward the paper guide arc plate 62 and the paper guide block 63.

[0056] Among them, the paper separation mechanism 6 also includes a paper guide arc plate 62 and a paper guide block 63. The paper guide arc plate 62 and the paper guide block 63 are both set in two, and are symmetrically arranged on both sides of the isosceles triangle block 61. The paper guide block 63 is fixed on both sides of the bottom of the isosceles triangle block 61. The paper guide arc plate 62 and the paper guide block 63 are respectively arranged on both sides of the bottom of the conveyor belt part 64, and the bottoms of the paper guide arc plate 62 and the paper guide block 63 are in an arc-shaped vertical downward state. Therefore, this setting makes it easy to separate the originally stacked paper vouchers to both sides through the top of the isosceles triangle block 61 and page them into multiple stacks of paper vouchers that have been paged. Then, under the action of the paper guide arc plate 62 and the paper guide block 63, when the multiple stacks of paper vouchers that have been paged fall to the top of the isosceles triangle block 61 of the next layer, the multiple stacks of paper vouchers facing the isosceles triangle block 61 of the next layer are in a vertical state.

[0057] Reference Figure 12 In this state, the top of the next layer of isosceles triangle blocks 61 is located directly below the paper guide arc plate 62 and the paper guide block 63. The paginated stacks of paper vouchers pass through the next layer of isosceles triangle blocks 61 and are paginated again. When the paper vouchers originally in a stack pass through multiple isosceles triangle blocks 61, they are divided into multiple thinner stacks of paper vouchers that are easy to crush.

[0058] Reference Figure 3-Figure 5 In this state, the shredding mechanism 5 includes two side brackets 51, which are symmetrically arranged on the inner wall of the shredding box body 1. A plurality of shredding parts are provided on the side brackets 51, and the shredding parts are arranged directly below the two sides of the isosceles triangle block 61. Therefore, the multiple stacks of paper vouchers that are paged into thinner sheets by the paper separation mechanism 6 will be cut into strip-shaped shredded paper by the shredding parts.

[0059] A shredder mechanism 5 is provided below the paper separation mechanism 6 for longitudinally shredding the paginated paper vouchers into paper strips, wherein multiple groups of thinner stacks of paper vouchers will be conveyed between the paper cutting edge block 52 and the shredder blade 53, thereby achieving cutting the thinner stacks of paper vouchers into strips of shredded paper.

[0060] The shredding part includes two paper cutting edge blocks 52, each of which has a knife groove 54 at the opposite end. The paper cutting edge blocks 52 are fixed on the side bracket 51, and two drive shafts 56 with opposite rotation directions are arranged between the two paper cutting edge blocks 52. A plurality of paper shredding blades 53 adapted to the knife groove 54 are fixedly mounted along the drive shaft 56. The side bracket 51 is provided with a plurality of drive motors 55, and the output end of the drive motor 55 is connected to the drive shaft 56. Therefore, after the drive motor 55 is turned on, the drive motor 55 drives the drive shaft 56 and the plurality of paper shredding blades 53 to rotate together, and the two adjacent drive shafts 56 rotate in opposite directions, that is, they both rotate toward the paper cutting edge block 52, thereby being able to carry thinner multi-stack paper certificates and better cut them into strip-shaped shredded paper through the knife groove 54.

[0061] Reference Figure 7 When the shredder 5 is in the state, a stacking mechanism 7 for collecting the paper strips is provided below the shredder mechanism 5. The stacking mechanism 7 is tilted to ensure that the shredded paper into strips will slide into the stacking mechanism 7 during the vertical hanging process and be stacked into a plurality of shredded paper strips. The stacking mechanism 7 includes a tilting box 71, which is bolted to the inner wall of the shredder box body 1, and the bottom of the tilting box 71 is a through hole. The stacking mechanism 7 also includes a flip bottom plate 72, one side of the flip bottom plate 72 is rotatably connected to one side of the bottom of the tilting box 71 by a rotating hinge 73, and the other side of the flip bottom plate 72 is attracted to the bottom of the tilting box 71 by a magnetic attraction mechanism. A magnet is provided on the side of the flip bottom plate 72 facing the tilting box 71, so when the magnetic attraction mechanism is turned on, the flip bottom plate 72 will be attracted to the bottom of the tilting box 71. When a plurality of shredded paper strips are released, it is only necessary to close the magnetic attraction mechanism, and the flip bottom plate 72 will flip open under the action of gravity. At this time, a plurality of shredded paper strips will fall onto the opened plurality of side flip plates 82.

[0062] The magnetic attraction mechanism is an electromagnetic generator, which is installed on the tilt box 71. The electromagnetic generator is a prior art and will not be elaborated on here.

[0063] Reference Figures 8-10 State, a paper lifting mechanism 8 is provided under the paper stacking mechanism 7 to lift the paper strips to the paper shredding mechanism 5 for secondary shredding, and the paper lifting mechanism 8 includes a lifting base 81, and the lifting base 81 is lifted and slid on the vertical slide rail 9 by an electric telescopic device. A plurality of side grooves 83 are linearly and equidistantly provided on both sides of the lifting base 81, and a rotating shaft 84 that passes through the side groove 83 is symmetrically provided on the lifting base 81. The paper lifting mechanism 8 also includes a side flip plate 82, and the side flip plate 82 is provided in multiple settings. The side flip plate 82 is flipped in the side groove 83 by the rotating shaft 84, so that multiple strips of shredded paper that fall on the side flip plate 82 can be lifted up, and then the multiple strips of shredded paper can be clamped in the process of flipping the side flip plate 82.

[0064] A lifting double-sided rack 86 is provided on one side of the lifting base 81, and driving gears 85 meshing with the double-sided rack 86 are coaxially fixed on the two rotating shafts 84. The two driving gears 85 are symmetrically arranged on both sides of the double-sided rack 86. Under the action of the external driving mechanism, the double-sided rack 86 is lowered, and then the rotating shaft 84 is rotated through engagement, and then the side flip plate 82 is rotated.

[0065] A vertical slide rail 9 is provided on the side wall of the crushing box body 1, and the paper lifting mechanism 8 slides on the vertical slide rail 9 through an external driving mechanism, wherein the vertical slide rail 9 is located in the middle position of the two driving shafts 56, so that under the action of the external driving mechanism, the paper lifting mechanism 8 can slide and lift on the vertical slide rail 9.

[0066] The width of the side flip plate 82 is smaller than the distance between two adjacent shredder blades 53. Therefore, when the side flip plate 82 is lifted, it will not be blocked by the shredder blades 53. Therefore, multiple strips of shredded paper are lifted by the side flip plate 82 and pass over the multiple shredder blades 53, thereby completing the secondary cutting of the horizontal strips of shredded paper, and crushing the horizontal strips of shredded paper into multiple small pieces, thereby crushing a stack of paper certificates to be shredded into shredded paper pieces that are difficult to splice, and completing the confidential shredding of the paper certificates to be shredded.

[0067] The working principle of the present invention is as follows:

[0068] The shredding box body 1 is provided with a top plate 4, and a paper feeding hole is opened on the top plate 4. Therefore, when shredding a stack of paper vouchers to be shredded, it is only necessary to directly put the stack of paper vouchers to be shredded into the shredding box body 1 through the paper feeding hole, and perform paging and multiple shredding in the shredding box body 1.

[0069] Then, since the shredding box body 1 is provided with a paper separation mechanism 6 for paging the stack of paper vouchers, when a stack of paper vouchers to be shredded touches the top of the isosceles triangle block 61, the stack of paper vouchers to be shredded will be divided into two parts, and divided into two parts from both sides of the isosceles triangle block 61. Both sides of the isosceles triangle block 61 are provided with pressing rollers 65 that press toward the conveyor belt portion 64. The pressing rollers 65 are pressed toward the conveyor belt portion 64 by the return spring 69, thereby ensuring that the pressing rollers 65 push the paged stacks of paper vouchers against the surface of the conveyor belt portion 64 under the action of the return spring 69, so that the paged stacks of paper vouchers can be moved together.

[0070] Then, under the action of the paper guide arc plate 62 and the paper guide block 63, when the paginated stacks of paper vouchers fall to the top of the isosceles triangle block 61 of the next layer, the paginated stacks of paper vouchers facing the isosceles triangle block 61 of the next layer are in a vertical state.

[0071] A shredder mechanism 5 is provided below the paper separation mechanism 6 for longitudinally shredding the paginated paper vouchers into paper strips, wherein multiple groups of thinner stacks of paper vouchers will be conveyed between the paper cutting edge block 52 and the shredder blade 53, thereby achieving cutting the thinner stacks of paper vouchers into strips of shredded paper.

[0072] After the drive motor 55 is turned on, the drive motor 55 rotates with the drive shaft 56 and the multiple shredder blades 53, and the two adjacent drive shafts 56 rotate in opposite directions, that is, they both rotate toward the paper cutting edge block 52, so that multiple thinner stacks of paper certificates can be better cut into strip-shaped shredded paper through the knife groove 54. A stacking mechanism 7 for collecting paper strips is provided below the shredder mechanism 5. The stacking mechanism 7 is tilted. When multiple strips of shredded paper are released, it is only necessary to close the magnetic attraction mechanism, and the flip bottom plate 72 flips open under the action of gravity. At this time, the multiple strips of shredded paper will fall onto the opened multiple side flip plates 82.

[0073] The side flip plates 82 are multiple settings, and the side flip plates 82 flip in the side grooves 83 through the rotating shafts 84, so that multiple strips of shredded paper that fall on the side flip plates 82 can be lifted up, and then the multiple strips of shredded paper can be clamped during the flipping of the side flip plates 82. The width of the side flip plates 82 is smaller than the distance between two adjacent shredder blades 53, so during the lifting process of the side flip plates 82, they will not be blocked by the shredder blades 53. Therefore, multiple strips of shredded paper are lifted by the side flip plates 82 and pass over the multiple shredder blades 53, thereby completing the secondary cutting of the horizontal strips of shredded paper, and crushing the horizontal strips of shredded paper into multiple small pieces, thereby achieving the crushing of a stack of paper certificates to be shredded into shredded paper blocks that are difficult to splice, and completing the confidential shredding of the paper certificates to be shredded.

[0074] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
