[0002] A bank card refers to a credit payment tool approved by a commercial bank for issuance to the society, which has all or part of the functions such as consumer credit, transfer settlement, cash deposit and withdrawal, etc. Bank cards have reduced the circulation of cash and checks, enabling banking services to break through the limitations of time and space and undergoing fundamental changes. A cancelled bank card refers to a card that a customer cancels at a bank branch by carrying an identity card and the bank card. The cancelled bank cards need to be centralized for destruction. When destroying, the cards are generally directly shredded, which places a large load on the machine and is not easy to handle.

[0003] It should be noted that the information disclosed in the background art part of the present invention is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of implication that this information constitutes the prior art known to those skilled in the art. Summary of the Invention

[0004] To solve the problems existing in the prior art, the present invention provides a shredding device for cancelled bank cards. When preprocessing the card surface, a grinding disc loaded with blades is used to rub the card surface, and the colors and raised numbers on the card surface can be rubbed into powder, effectively reducing the thickness of the card and reducing the load for the next step of cutting. Further, a cutting roller driven by a worm and worm gear can cut the card with reduced thickness into strips, and the worm and worm gear drive effectively reduces the occurrence of gear jamming during rotation. With the action of the air extraction module and the cooling fan, a negative pressure area can be formed at the bottom of the machine, enabling all internal substances to settle down, and the debris can also be centrally processed after opening the closed cover after long-term operation.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0009] Based on the above technical solution, the fine shearing mechanism includes a fine shearing box and a crushing roller. The fine shearing box is connected to the outlet position of the initial shearing box. A pair of crushing rollers are connected to the interior of the fine shearing box through bearings. Short saw blades that intersect with each other are evenly installed on the surface of the crushing roller and are driven to rotate by a built-in motor. The crushing roller and the splitting roller are arranged in a cross shape.

[0010] Based on the above technical solution, the height of the splitting plate is lower than the height of the loading bottom box. The detachable connection method between the air extraction module and the closed cover can be a snap connection or a sliding connection.

[0011] On the basis of the above technical solution, the first grinding disc is a solid metal block, and friction particles are made on the surface. The second grinding disc is hollow inside and short blades with a peeling card surface coating are made on the surface. An electric drive module and a jet module equipped with a time sensor are integrated on the anti-blocking module.

[0012] On the basis of the above technical solution, the highest points of the splitting rollers are all annular cutting blades, and smooth rounding is done in the annular grooves. The initial cutting box is made by welding a square hopper at the upper part and a trapezoidal hopper at the lower part.

[0013] On the basis of the above technical solution, the distance between the blades on the second grinding disc and the first grinding disc is less than the thickness of two cards, and all are rounded.

[0029] With such a setting, the cancelled bank cards to be shredded can be put in from both sides simultaneously. When entering the treatment box 201, the first grinding disc 203 and the second grinding disc 205 clamp the card in the middle and grind it thin, erasing the raised characters and colors on the card into powder. And under the protection of the movable cover 202, frictional flying chips can be prevented from popping out. The detachable first grinding disc 203 can be removed for treatment after long-term use. The second grinding disc 205 can avoid blockage and smooth operation under the action of the anti-blocking module 206;

[0030] Embodiment 2, please refer to Figure 5 , on the basis of Embodiment 1, the foam discharging mechanism 1 includes a loading bottom box 101, a splitting plate 102, an air extraction module 103, and a sealing cover 104.

The splitting plate 102 is vertically installed at the middle position inside the loading bottom box 101, which can process the shredded powder from both sides. The air extraction modules 103 are bolted to both sides inside the loading bottom box 101, and the sealing cover 104 for preventing leakage is detachably connected to the outlet position of the air extraction module 103;

[0031] With such a setting, under the action of the air extraction module 103 and the cooling fan 302, a negative pressure area can be formed at the bottom of the machine, so that all internal substances can settle down. Also, the sealing cover 104 can be opened for centralized treatment of debris after long-term operation;

[0032] Embodiment 3, please refer to Figure 2, on the basis of the first embodiment, the primary shearing mechanism 3 includes a primary shearing box 301, a cooling fan 302, a driving assembly 303, a vertical worm 304, a driving worm gear 305, a splitting roller 306, an attachment plate 307, and a transmission gear 308. Three cooling fans 302 are transversely arranged and installed on the front surface of the primary shearing box 301. A driving assembly 303 is connected by bolts at a position near the rear end on one side of the outside of the primary shearing box 301. The output end of the driving assembly 303 is key-connected to a vertical worm 304. A driving worm gear 305 for driving a splitting roller 306 to rotate actively is engaged with the front part of the vertical worm 304. One end of the splitting roller 306 is key-connected to a single transmission gear 308.

The other end of the splitting roller 306 is connected to the surface of the attachment plate 307 through a bearing;

[0033] With such a setting, the worm and worm gear transmission is adopted to drive the splitting roller 306 to rotate and split the thinned cards, which can effectively reduce the occurrence of tooth beating;

[0034] Embodiment Four, please refer to Figure 1 and Figure 2 , on the basis of the first embodiment, the fine shearing mechanism 4 includes a fine shearing box 401 and a crushing roller 402. The fine shearing box 401 is connected to the outlet position of the primary shearing box 301. A pair of crushing rollers 402 are connected to the inside of the fine shearing box 401 through bearings. Short saw blades that cross each other are evenly installed on the surface of the crushing roller 402 and are driven to rotate by a built-in motor. The crushing roller 402 and the splitting roller 306 are arranged in a cross shape;

[0035] With such a setting, the card strips after splitting can be refined into foam by the short saw blades between the crushing rollers 402;

[0036] According to needs, the height of the splitting plate 102 is lower than the height of the loading bottom box 101. The detachable connection method between the air extraction module 103 and the closed cover 104 can be snap connection or sliding connection;

[0037] With such a setting, after the fine sheared powder is roughly divided into two sides for output, the closed cover 104 can be directly removed when centralized output is required for unified processing;

The second grinding disc 205 is hollow inside and has short blades for peeling the card surface coating on its surface. The anti-blocking module 206 integrates an electric drive module for driving the second grinding disc 205 and a jet module equipped with a time sensor;

[0039] With such a setting, the colored coating on the card can be directly shaved off, and the thickness of the card can be reduced. Moreover, after a specified time, air can be jetted to clean the blockage;

[0040] As required, the highest points of the splitting rollers 306 are all annular cutting blades, and the annular grooves are all processed with smooth rounding. The primary splitting box 301 is made by welding a square hopper at the upper part and a trapezoidal hopper at the lower part;

[0041] With such a setting, the cutting blades can cut the thinned cards into strips. The annular grooves can prevent the cards from getting stuck in the gaps after cutting. The trapezoidal hopper can effectively concentrate the split strips in a certain area to enter the next process;

[0042] As required, the distance between the blades on the second grinding disc 205 and the first grinding disc 203 is less than the thickness of two cards, and all are processed with rounding;

[0043] With such a setting, when multiple cards are inserted, it can be ensured that they will not be stuck in the gaps under the action of rounding. Moreover, the distance less than the thickness of two cards can ensure that both sides of the cards can be processed and the cards will not be left unprocessed due to stacking.

[0044] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
