[0002] In financial work, financial vouchers, as written proofs for recording economic transactions, clarifying economic responsibilities, and serving as the basis for registering accounting books, play an important role. Since financial vouchers need to be preserved for a certain period and often need to be destroyed after the expiration date, shredding is a commonly used method. Traditional shredding methods include manual tearing and shredding with a paper shredder, etc.

[0003] Currently, existing technology financial voucher shredders are all relatively small in size. With the development of the company, the quantity of voucher documents has increased significantly. The efficiency of ordinary paper shredders for continuous shredding operations is not high, and generally, the shredded debris is temporarily stored inside the machine body and cannot be taken out immediately. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a financial voucher shredding device capable of recycling debris, which solves the problems of low efficiency in shredding financial vouchers and the inability to immediately take out shredded paper scraps.

The other end of the second toothed plate is fixedly connected to the outer wall of the pushing plate. A number of impact balls are arranged on the side of the pushing plate close to the crushing roller. The top ends of the impact balls are fixedly connected with first springs. The top ends of the first springs are fixedly connected to the inner wall of the crushing box.

[0009] Preferably, a filter screen is arranged on the left side of the impact ball. The filter screen is located on the right side of the crushing roller. A dust extraction pipe is arranged at the top end of the pushing plate. The other end of the dust extraction pipe penetrates through the outer wall of the outer box and is fixedly connected with a dust extractor. The bottom end of the dust extractor is fixedly connected to the outer wall of the outer box.

[0010] Preferably, the pushing component includes a transmission rod fixedly connected to the middle of the outer wall of the second drive shaft. The other end of the transmission rod is rotatably connected to a pull rod. The other end of the pull rod is rotatably connected to the top end of the pushing plate. The two sides of the outer wall of the pushing plate are slidably connected to the inner wall of the outer box.

[0011] Preferably, a third spring is fixedly connected to the bottom end of the guide block. The other end of the third spring is fixedly connected to the inner wall of the telescopic plate. The highest point of the guide block is lower than the horizontal position of the highest point of the outer wall of the arc-shaped guide rail.

[0012] Preferably, a plurality of second springs are fixedly connected to the top end of the telescopic plate, and the other ends of the second springs are fixedly connected to the inner wall of the pushing plate.

[0013] Preferably, a guiding inclined plate is arranged on one side of the inner wall of the outer box body where the input conveyor belt is located. The bottom end of the guiding inclined plate is fixedly connected to the inner wall of the outer box body, and both sides of the outer walls of the input conveyor belt and the output conveyor belt are fixedly installed on the inner wall of the outer box body.

[0014] Working principle: First, place the financial vouchers to be shredded on the top of the input conveyor belt on the right side. Then, start the double-headed motor through the external controller, drive the first drive shafts and the second drive shafts on both sides to rotate, so that the shredding rollers on both sides rotate. At the same time, drive the output conveyor belts and the input conveyor belts on both sides to start synchronously through the coupling drive belt 1 and the coupling drive belt 2. A large number of financial vouchers will enter the interior of the outer box along the surface of the input conveyor belt, and then fall onto the inclined platform on the inner wall of the shredding box, and then slide into the shredding cavity to receive the shredding effect of the shredding rollers. The shredding rollers on both sides rotate in reverse under the meshing action of gear 1 and gear 2 to shred the vouchers. At the same time, gear 1 and gear 2 on both sides will drive the drive sleeve to slide reciprocally on both sides of the outer wall of the shredding box through the eccentric rod, and drive the opening and closing plates 1 and the opening and closing plates 2 on both sides to open intermittently through the connecting rod, so as to ensure that the financial vouchers can fully receive the shredding of the shredding rollers in the shredding cavity and can be shredded into finer debris. And during the movement of the opening and closing plate 1, it will pull the toothed plate 1 to slide reciprocally on the outer wall of the shredding box, so as to pull the push plate to move reciprocally in the dust collection cavity under the action of gear 3, and then can collide with the impact ball during each reciprocating movement, so that it impacts the filter screen under the action of spring 1, thus preventing the shredded paper from adhering to the outer wall of the filter screen and affecting the dust extraction efficiency. And during the shredding process, the dust extractor on the top of the outer box will be started to make the interior of the dust collection cavity form a negative pressure through the dust extraction pipe, so that the dust during the shredding process can enter the dust collection cavity through the filter screen and be drawn out of the shredding box along the dust extraction pipe. During the shredding, the second drive shaft on the other side will drive the rotation, and then pull the pull rod to drive the pushing plate to slide on the inner wall of the shredding box, and then push the shredded debris to the position of the guide inclined plate, and be pushed along the inclined surface onto the input conveyor belt, and then be output to the inner wall of the outer box, thus completing the recovery of the debris. And during the pushing process of the pushing plate, the guiding block will be squeezed downward under the action of the lower side of the outer walls of the arc-shaped guide rails on both sides, and the spring 3 will slide in the inner wall of the telescopic pushing plate, so that the bottom end of the telescopic pushing plate always adheres to the bottom of the inner wall of the outer box to push out the paper scraps. And during the return process of the pushing plate, under the elastic reset action of the spring 3, it will be squeezed upward along the upper side of the outer wall of the arc-shaped guide rail to lift the telescopic pushing plate. The telescopic pushing plate will slide and contract into the inner wall of the pushing plate under the compression of the spring 2, and after leaving the upper side of the outer wall of the arc-shaped guide rail, it will pop out to the lowest position again under the action of the spring 2 to keep close to the bottom of the inner wall of the outer box, so as to ensure that the un-pushed debris will not be pushed to the other side of the outer box during the return path of the pushing plate, thus causing the situation that the debris stays inside the outer box. The device has a high degree of integration and automation.

[0015] The present invention provides a financial voucher shredding device capable of recycling debris. It has the following beneficial effects:

[0016] 1. The present invention realizes the rapid shredding of financial vouchers through an integrated structure, facilitating continuous shredding operations for a large number of vouchers. The shredded debris can be immediately removed, and the shredding efficiency is high.

[0017] 2. The present invention utilizes the opening and closing plate linkage to drive the pushing component. The movement of the opening and closing plate drives the toothed plate and gear to make the pushing plate reciprocate. The impact ball impacts the filter screen to prevent debris adhesion. At the same time, the dust extractor forms negative pressure dust suction through the dust extraction pipe, effectively avoiding dust flying and filter screen blockage.

[0018] 3. The present invention drives the pushing plate by means of the second drive shaft, transmission rod and pull rod, and cooperates with the guide block, arc-shaped guide rail, telescopic plate and spring. When the pushing plate pushes the debris, the telescopic plate adheres tightly to the bottom of the box, and automatically contracts when returning, avoiding debris residue and realizing efficient recovery of debris.

[0019] 4. The present invention sets a double-headed motor, shredding roller and gear transmission structure. The first drive shaft drives the shredding roller to flip and shred the vouchers. The first and second gears drive the eccentric rod to intermittently open the opening and closing plate, ensuring that the vouchers are fully shredded into fine debris and improving the shredding effect.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment:

[0033] As Figures 1 - 3 shown, the embodiment of the present invention provides a financial voucher crushing device capable of recycling debris, including an outer box body 1. A crushing box 7 is fixedly connected to the top of the inner wall of the outer box body 1. A double-headed motor 9 is arranged on one side of the outer wall of the crushing box 7. The top of the double-headed motor 9 is fixedly connected to the inner wall of the outer box body 1. A crushing cavity is opened in the inner wall of the crushing box 7. Two first drive shafts 23 are rotatably connected to the inner wall of the crushing cavity of the crushing box 7. A crushing roller 8 is fixedly connected to the outer wall of the first drive shaft 23. One end of the first drive shaft 23 on one side penetrates through the outer wall of the crushing box 7 and is fixedly connected to the drive end of the double-headed motor 9, and the other end penetrates through the outer wall of the crushing box 7 and is fixedly connected to a second gear 14. The outer wall of the second gear 14 is meshed with a first gear 12, and the inner wall of the first gear 12 is fixedly connected to the outer wall of the first drive shaft 23 on the other side. Among them, as Figure 8 shown, an input conveyor belt 6 is connected to the outer wall of the first drive shaft 23 near the crushing box 7 through a second coupling drive belt 10. The input conveyor belt 6 is located at the top of the outer wall of the outer box body 1. The other drive end of the double-headed motor 9 is fixedly connected to a second drive shaft 29. An output conveyor belt 4 is connected to the outer wall of the second drive shaft 29 through a first coupling drive belt 5. The output conveyor belt 4 is located at the bottom of the other side of the outer wall of the outer box body 1. A feeding inclined plate 15 is arranged on one side of the inner wall of the outer box body 1 where the input conveyor belt 6 is located. The bottom end of the feeding inclined plate 15 is fixedly connected to the inner wall of the outer box body 1. Both sides of the outer walls of the input conveyor belt 6 and the output conveyor belt 4 are fixedly installed on the inner wall of the outer box body 1.

[0034] Specifically, a controller is provided on the outer wall of the outer box body 1 to facilitate the control of the start of the internal dual-head motor 9. The two driving ends on both sides of the dual-head motor 1 are driven simultaneously, and the selected dual-head motor 9 is the SycoTec50100AC-duo. The motor can output a maximum power of 7.5 kW and can continuously provide a torque of 1 Nm at 50,000 revolutions per minute. The powerful power output requires the internal structure of the motor to withstand greater forces, and this model of motor can stably output high power and torque. The power supply line will be hidden in the outer shell of the outer box body 1 during actual design and can carry sufficient load. The two ends of the first drive shaft 23 on the other side are rotatably connected to the inner wall of the crushing box 7. The first coupling belt 5 and the second coupling belt 10 are both composed of a high-strength belt and two synchronous pulleys, and will drive the input conveyor belts 6 and the output conveyor belt 4 on both sides for belt drive under the drive of the second drive shaft 29. During actual design, the two coupling belts can also be replaced with a sprocket and chain structure for more stable transmission. The guiding inclined plate 15 does not contact the surface of the output conveyor belt 4, but only the uppermost end is above the surface of the conveyor belt. During actual design, corresponding frames will be installed on both sides of the input conveyor belt 6 and the output conveyor belt 4 to fixedly install them on the inner wall of the outer box body 1.

[0035] As Figure 4 , Figure 6 and Figure 7 As shown, eccentric rods 17 are fixedly connected to the outer walls of the first gear 12 and the second gear 14. Transmission sleeves 13 are sleeved on the outer walls of the eccentric rods 17. The top ends of the transmission sleeves 13 are fixedly connected to connecting rods 18. The outer walls of the connecting rods 18 are slidably connected to the outer wall of the crushing box 7. The bottom end of one connecting rod 18 is fixedly connected to a first opening and closing plate 21. The two sides of the outer wall of the first opening and closing plate 21 are slidably connected to the inner wall of the crushing box 7. The first opening and closing plate 21 is located at the bottom of the crushing roller 8. The bottom end of the other connecting rod 18 is fixedly connected to a second opening and closing plate 24. The two sides of the outer wall of the second opening and closing plate 24 are slidably connected to the inner wall of the crushing box 7. The opposite ends of the second opening and closing plate 24 and the first opening and closing plate 21 are in a shape that fits each other.

[0036] Specifically, during actual design, the bottom of the crushing chamber will be designed with a downward funnel-shaped inclination to ensure that the maximum opening degrees of the first opening and closing plates 21 and the second opening and closing plates 24 on both sides do not block the falling of the crushed debris. The transmission sleeve 13 is snap-fitted and sleeved on the outer wall of the eccentric rod 17, and under the action of the connecting rod 18, it can stably pull the first opening and closing plate 21 and the second opening and closing plate 24 to expand to both sides. The splicing distance at the middle connection of the first opening and closing plate 21 and the second opening and closing plate 24 can be designed according to actual conditions to ensure the residence time of the vouchers in the crushing chamber and improve the crushing effect.

[0037] As Figure 4 and Figure 5As shown in the figure, a dust collection chamber is provided near the left side of the crushing chamber in the crushing box 7. A first toothed plate 25 is fixedly connected to the outer wall of the first opening and closing plate 21. The bottom end of the first toothed plate 25 is slidably connected to the outer wall of the crushing box 7. The top end of the first toothed plate 25 is meshed with a third gear 26. The middle of the third gear 26 is rotatably connected to the outer wall of the crushing box 7. The upper side of the outer wall of the third gear 26 is meshed with a second toothed plate 27. The other end of the second toothed plate 27 is fixedly connected to a pushing plate 20. The pushing plate 20 is located on the inner wall of the dust collection chamber. A number of impact balls 19 are arranged on the side of the pushing plate 20 close to the crushing roller 8. The top end of the impact ball 19 is fixedly connected to a first spring 22. The top end of the first spring 22 is fixedly connected to the inner wall of the crushing box 7. A filter screen 16 is arranged on the left side of the impact ball 19. The filter screen 16 is located on the right side of the crushing roller 8. A dust extraction pipe 3 is arranged at the top end of the pushing plate 20. The other end of the dust extraction pipe 3 penetrates through the outer wall of the outer box body 1 and is fixedly connected to a dust extractor 2. The bottom end of the dust extractor 2 is fixedly connected to the outer wall of the outer box body 1.

[0038] Specifically, the gap size of the filter screen 16 only allows dust to pass through to prevent shredded paper from entering. During the reciprocating movement of the first opening and closing plate 21, it will drive the relative sliding of the first toothed plate 25 and the second toothed plate 27, thereby pushing the pushing plate 20 to move inside the dust collection chamber and contact the impact ball 19, so as to impact the filter screen 16 and prevent debris from adhering. The top end of the pushing plate 20 is at the same horizontal level as the middle of the impact ball 19. An outlet is provided on one side of the outer wall of the dust extractor 2 for facilitating the removal of dust. In actual use, the dust extractor 2 can also be arranged on the lower side of the outer wall of the outer box body 1. The start of the dust extractor 2 is also controlled by an external controller.

[0039] As Figures 8 - 10 As shown in the figure, the other end of the second drive shaft 29 is fixedly connected to a transmission rod 35. The other end of the transmission rod 35 is rotatably connected to a pull rod 28. The other end of the pull rod 28 is rotatably connected to a pushing plate 11. Both sides of the outer wall of the pushing plate 11 are slidably connected to the inner wall of the outer box body 1. A telescopic plate 32 is slidably connected to the inner wall of the pushing plate 11. Guide blocks 31 are slidably connected to both sides of the outer wall of the telescopic plate 32. Arc-shaped guide rails 30 are fixedly connected to both sides of the inner wall of the outer box body 1. The shape of the outer wall of the arc-shaped guide rail 30 fits the shape of the inner wall of the guide block 31. The bottom end of the guide block 31 is fixedly connected to a third spring 34. The other end of the third spring 34 is fixedly connected to the inner wall of the telescopic plate 32. The highest point of the guide block 31 is lower than the horizontal position of the highest point of the outer wall of the arc-shaped guide rail 30. A number of second springs 33 are fixedly connected to the top end of the telescopic plate 32. The other end of the second springs 33 is fixedly connected to the inner wall of the pushing plate 11.

[0040] Specifically, the lower side of the outer wall at the highest point of the arc-shaped guide rail 30 should be higher than the highest point where the guide block 31 can slide on the inner wall of the telescopic block 32. Therefore, when the telescopic plate 32 moves outward, the guide block 31 will gradually come into contact with and press against the outer wall of the arc-shaped guide rail 30 during the movement. As a result, the guide block 31 presses down the spring three 34 and slides, and then rebounds after leaving the lower side of the outer wall of the arc-shaped guide rail 30. Then, when the telescopic plate 32 returns to the deepest part of the inner wall of the outer box 1 along with the pushing plate 11, the lower side of the outer wall of the guide block 31 will gradually come into contact with and press against the upper side of the outer wall of the arc-shaped guide rail 30. Consequently, the telescopic block 32 compresses the spring two 33 and slides upward on the inner wall of the pushing plate 11, causing the bottom end of the telescopic plate 32 to move away from the bottom of the inner wall of the outer box 1, preventing the pushing plate 11 from pushing the subsequent falling paper scraps deeper into the inner wall of the outer box 1 during the return process. The side of the pushing plate 11 close to the double-headed motor 9 is made of heavier stainless steel material, and the other side is made of plastic material, which facilitates the sliding of the pushing plate 11 being pulled by the pulling plate 28.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
