Description

Technical Field

[0001] This application relates to the field of office equipment technology, and more specifically to an automatic paper shredder. Background Technology

[0002] A paper shredder is a common office appliance whose main function is to cut paper or other documents into small pieces for the purpose of confidential and secure handling of sensitive information. A paper shredder typically consists of a set of rotating blades, a guide comb, and a drive motor. Paper is fed through the interlocking blades and shredded into many small pieces. Early paper shredders were relatively simple in design, primarily using manual paper feeding. Users had to put documents one sheet at a time into the feed slot, and the shredder would cut the paper into shreds using its built-in blades. While this met basic shredding needs, it was inefficient, especially when processing large volumes of documents, requiring significant time and manpower. Currently, most automatic paper shredders incorporate a paper storage compartment. This compartment, usually located at the top of the shredder, holds multiple sheets of paper. Users can place a stack of papers into the compartment, and the shredder automatically feeds the paper from the compartment one sheet at a time, greatly improving shredding efficiency and reducing manual intervention.

[0003] For example, Chinese utility model patent CN217140681U discloses a paper storage bin structure and an automatic paper shredder containing the structure. The structure includes a paper pressing mechanism located on the lower end face of the shredder end cover, which is used to press the paper together. The structure also includes a paper storage bin located below the shredder end cover. The paper storage bin includes a bin body for placing paper, and one end of the bin body is provided with a paper outlet. The paper outlet corresponds to a paper feed roller to drive the paper downward. A gap is provided between the paper outlet and the paper feed roller to form a channel for the paper to enter. The paper storage bin is also provided with a paper support structure at the paper outlet end, and the height of the paper support structure is higher than the height of the inner surface of the paper storage bin. This technical solution solves the drawbacks of manual paper feeding in traditional paper shredders by using a paper storage bin structure. However, such automatic paper shredders often handle complete sets of documents with staples or paper clips. Usually, the staples or paper clips need to be removed first, otherwise the paper shredder cannot automatically shred the entire set of documents. Some automatic paper shredders add a staple removal component to handle the staples or paper clips on the documents. However, during the staple removal process, the fallen paper scraps and staples will accumulate in the paper storage bin, requiring regular manual cleaning. This cleaning work is not only tedious, but may also increase maintenance costs and operational risks. Summary of the Invention

[0004] The technical problem this application aims to solve is to provide an automatic paper shredder that, by setting an outlet and a rotatable baffle in the paper storage bin, allows users to directly clean up the fallen materials in the paper storage bin, thereby improving cleaning efficiency and extending the service life of the equipment.

[0005] This application provides an automatic paper shredder, including a paper storage bin. The paper storage bin includes a cavity for placing paper, and a discharge port is provided in the cavity for discharging dropped material from the paper storage bin. A baffle is rotatably connected to the cavity, and the baffle is adapted to the discharge port for rotating to open or close the discharge port.

[0006] In this technical solution, the cavity design ensures that the paper to be shredded can be neatly placed inside, facilitating subsequent automatic paper feeding and shredding operations. The discharge port is an opening located within the cavity, used to discharge fallen items from the paper storage bin, such as shredded paper, staples, paper clips, etc. A baffle is installed at the discharge port to control its opening and closing. The baffle design ensures that the paper storage bin remains sealed during normal operation, preventing dust and other debris from entering. At the same time, the discharge port can be easily opened when cleaning is required. The baffle is connected to the cavity via a rotating connection, making the opening and closing operation of the baffle simple and convenient, improving cleaning efficiency. The rotating connection can be implemented in various ways, such as hinge connection, rotating shaft connection, etc. By setting up the discharge port and baffle, fallen items in the paper storage bin can be directly discharged, reducing the frequency and workload of manual cleaning, reducing the risk of paper jams or equipment failures caused by the accumulation of fallen items, thereby extending the service life of the equipment.

[0007] As an improvement, a reset elastic element is installed between the discharge port and the baffle. The baffle rotates to open the discharge port under the gravity of the fallen object, and closes the discharge port by rotating the reset elastic element. In this technical solution, the opening and closing of the baffle is achieved by its own rotation, which is simple to operate and highly automated. By adding a reset elastic element between the discharge port and the baffle, its main function is to provide an elastic force so that the baffle can automatically reset and close the discharge port after the fallen object is discharged. When fallen objects (such as staples, shredded paper, etc.) accumulate to a certain level in the paper storage compartment, the gravity of these fallen objects will act on the baffle, causing the baffle to overcome the elastic force of the reset elastic element and rotate, thereby opening the discharge port and allowing the fallen objects to be discharged. Once the fallen objects are discharged, the gravity on the baffle disappears, and the elastic force of the reset elastic element will push the baffle to reset, causing it to automatically close the discharge port and restore the sealing state of the paper storage compartment. The automatic opening and closing mechanism reduces the frequency and workload of manual cleaning. Users do not need to manually clean the debris in the paper storage compartment regularly, reducing maintenance costs and operational complexity.

[0008] As an improvement, a pin is provided between the outlet and the baffle, and the outlet and the baffle are rotatably connected by the pin. The reset elastic element is fitted onto the pin. In this technical solution, the outlet and the baffle are rotatably connected by a pin. The pin connection is a simple and reliable mechanical connection method, which can ensure that the baffle can rotate smoothly when needed, thereby realizing the opening and closing of the outlet. Fitting the reset elastic element onto the pin further simplifies the structure, improves installation efficiency, and reduces manufacturing costs and maintenance difficulty.

[0009] As an improvement, the outlet is provided with a first connecting seat adapted to the pin, and the baffle is provided with a second connecting seat adapted to the pin. Both the first and second connecting seats are connected to the pin. In this technical solution, the design of the first and second connecting seats provides a stable connection point. The baffle can rotate smoothly around the pin, reducing jamming caused by mechanical friction. The connection between the first and second connecting seats and the pin ensures a more reliable connection between the baffle and the outlet, preventing the pin from loosening or shifting during operation. The cooperation between the connecting seats and the pin simplifies the assembly process, reducing assembly time and costs.

[0010] As an improvement, the discharge outlet is provided with a limiting step adapted to the baffle, which limits the rotation range of the baffle. In this technical solution, the limiting step is located at the discharge outlet and adapted to the baffle. The limiting step abuts against the edge of the baffle, ensuring that the baffle can be accurately positioned when closing the discharge outlet, preventing incomplete closure of the discharge outlet due to excessive rotation of the baffle, and improving reliability.

[0011] As an improvement, the reset elastic element is a torsion spring. In this technical solution, the torsion spring can provide a stable torsional force, ensuring that the baffle can be reset smoothly and reliably after the dropped object is discharged. The torsion spring has high durability and can maintain good elastic performance after multiple uses, reducing mechanical failures caused by long-term use. The torsion spring is small in size, saving installation space. Users do not need to manually open and close the discharge port, reducing operation steps and improving the user experience.

[0012] As an improvement, a paper outlet is provided at one end of the cavity, and a discharge outlet is provided at the other end of the cavity. In this technical solution, the paper outlet at one end of the cavity serves as the channel for paper to enter the subsequent shredding unit from the paper storage bin. The design of the paper outlet ensures that the paper can be smoothly driven by the paper feed rollers into the subsequent shredding unit. The discharge outlet is located at the other end of the cavity, opposite to the paper outlet, so that paper processing and waste discharge do not interfere with each other, making the space utilization in the paper storage bin more reasonable. The arrangement of the paper outlet and discharge outlet makes the flow path of paper and waste smoother, reducing the risk of paper jams or equipment failures caused by the mixing of paper and waste, and improving the reliability and stability of the equipment.

[0013] As an improvement, a receiving groove is provided within the cavity to accommodate fallen objects, and the discharge outlet is located at the bottom of the receiving groove. In this technical solution, the receiving groove provides a centralized space for collecting and temporarily storing fallen objects, preventing them from scattering randomly within the cavity and affecting the normal operation of the equipment. The discharge outlet, located at the bottom of the receiving groove, utilizes gravity to allow fallen objects to naturally gather at the bottom of the receiving groove and be smoothly discharged through the outlet, reducing the risk of blockage and extending the service life of the equipment.

[0014] As an improvement, the receiving groove is provided with a guide ramp, which is used to guide the fallen object to the discharge outlet. In this technical solution, the guide ramp is designed to slope downwards from the top or side of the receiving groove, pointing towards the discharge outlet. Its main function is to guide the fallen object to the discharge outlet. The design of the guide ramp utilizes gravity, allowing the fallen object to slide naturally to the discharge outlet under its own weight and finally be discharged from the cavity, reducing the residence time of the fallen object in the receiving groove and improving the discharge efficiency.

[0015] As an improvement, the receiving groove protrudes outward relative to the bottom of the cavity. In this technical solution, the receiving groove forms a distinct recessed area at the bottom of the cavity, specifically for collecting and temporarily storing dropped items. This allows dropped items to be collected more concentratedly within the receiving groove, preventing them from scattering within the cavity and reducing interference with other components inside the cavity. The outward protrusion of the receiving groove creates an independent collection area, making more rational use of space within the cavity and reducing space waste.

[0016] As an improvement, the receiving groove and the cavity are integrally formed. In this technical solution, the integral forming design reduces structural problems caused by loose or damaged connection points, improves overall stability and reliability, extends the service life of the equipment, reduces assembly steps in the manufacturing process, simplifies the production process, and lowers manufacturing costs.

[0026] like Figures 1 to 4 As shown, this application discloses an automatic paper shredder, including a paper storage bin 1. The paper storage bin 1 includes a cavity 11 for placing paper, and a discharge port 12 is provided inside the cavity 11 for discharging debris from the paper storage bin 1. A baffle 2 is rotatably connected to the cavity 11, and the baffle 2 is adapted to the discharge port 12. The baffle 2 is used to rotate open or close the discharge port 12. The design of the cavity 11 ensures that the paper to be shredded can be neatly placed inside, facilitating subsequent automatic paper feeding and shredding operations. The discharge port 12 is an opening provided inside the cavity 11 for discharging debris from the paper storage bin 1, such as shredded paper, staples, paper clips, etc. By providing the baffle 2 at the discharge port 12, the baffle 2... The baffle 2 is designed to control the opening and closing of the discharge port 12. During normal operation, the paper storage bin 1 remains sealed to prevent dust and other debris from entering. At the same time, the discharge port 12 can be easily opened when cleaning is required. The baffle 2 is connected to the cavity 11 by a rotating connection, which makes the opening and closing of the baffle 2 simple and convenient, improving cleaning efficiency. The rotating connection can be achieved in various ways, such as hinge connection, rotating shaft connection, etc. By setting the discharge port 12 and the baffle 2, the fallen materials in the paper storage bin 1 can be directly discharged, reducing the frequency and workload of manual cleaning, reducing the risk of paper jams or equipment failures caused by the accumulation of fallen materials, thereby extending the service life of the equipment.

[0027] More specifically, such as Figure 3As shown, a reset elastic element 3 is installed between the discharge port 12 and the baffle 2. The baffle 2 rotates to open the discharge port 12 under the gravity of the falling object, and closes the discharge port 12 by rotating the reset elastic element 3. The opening and closing of the baffle 2 is achieved by its own rotation, which is simple to operate and highly automated. By adding a reset elastic element 3 between the discharge port 12 and the baffle 2, its main function is to provide an elastic force so that the baffle 2 can automatically reset and close the discharge port 12 after the falling object is discharged. When there are falling objects (such as staples, shredded paper) in the paper storage compartment 1, When debris (such as dust) accumulates to a certain extent, the weight of these fallen objects will act on the baffle 2, causing the baffle 2 to rotate against the elastic force of the reset elastic element 3, thereby opening the discharge port 12 and allowing the fallen objects to be discharged. Once the fallen objects are discharged, the weight on the baffle 2 disappears, and the elastic force of the reset elastic element 3 will push the baffle 2 to reset, causing it to automatically close the discharge port 12 and restore the sealed state of the paper storage compartment 1. The automatic opening and closing mechanism reduces the frequency and workload of manual cleaning. Users do not need to manually clean the debris in the paper storage compartment 1 regularly, reducing maintenance costs and operational complexity.

[0028] More specifically, such as Figure 3 As shown, a pin 4 is provided between the outlet 12 and the baffle 2. The outlet 12 and the baffle 2 are rotatably connected by the pin 4. The reset elastic element 3 is fitted onto the pin 4. The outlet 12 and the baffle 2 are rotatably connected by the pin 4. The pin 4 connection is a simple and reliable mechanical connection method, which can ensure that the baffle 2 can rotate smoothly when needed, thereby realizing the opening and closing of the outlet 12. Fitting the reset elastic element 3 onto the pin 4 further simplifies the structure, improves installation efficiency, and reduces manufacturing costs and maintenance difficulty.

[0029] More specifically, such as Figure 3 As shown, the outlet 12 is provided with a first connecting seat 13 adapted to the pin 4, and the baffle 2 is provided with a second connecting seat 21 adapted to the pin 4. Both the first connecting seat 13 and the second connecting seat 21 are connected to the pin 4. The design of the first connecting seat 13 and the second connecting seat 21 provides a stable connection point. The baffle 2 can rotate smoothly around the pin 4, reducing the jamming caused by mechanical friction. Through the connection of the first connecting seat 13 and the second connecting seat 21 with the pin 4, the connection between the baffle 2 and the outlet 12 is more reliable, preventing the pin 4 from loosening or shifting during operation. Through the cooperation between the connecting seat and the pin 4, the assembly process is simpler, reducing assembly time and cost.

[0030] More specifically, such as Figure 3As shown, the outlet 12 is provided with a limiting step 121 adapted to the baffle 2. The limiting step 121 is used to limit the rotation range of the baffle 2. The limiting step 121 is located at the outlet 12 and is adapted to the baffle 2. The limiting step 121 abuts against the edge of the baffle 2 to ensure that the baffle 2 can be accurately positioned when closing the outlet 12, preventing the outlet 12 from being incompletely closed due to excessive rotation of the baffle 2, and improving the reliability of use. More specifically, such as Figure 3 As shown, the reset elastic element 3 is a torsion spring. The torsion spring can provide a stable torsional force to ensure that the baffle 2 can be reset smoothly and reliably after the dropped object is discharged. The torsion spring has high durability and can maintain good elastic performance after multiple uses, reducing mechanical failures caused by long-term use. The torsion spring is small in size, saving installation space. Users do not need to manually open and close the discharge port 12, reducing operation steps and improving the user experience.

[0031] More specifically, such as Figure 1 and Figure 4 As shown, a paper outlet 14 is provided at one end of the cavity 11, and an outlet 12 is provided at the other end of the cavity 11. The paper outlet 14 at one end of the cavity 11 is the channel through which paper enters the subsequent shredding unit from the paper storage bin 1. The design of the paper outlet 14 ensures that the paper can be smoothly driven by the paper feed rollers and enter the subsequent shredding unit. The outlet 12 is located at the other end of the cavity 11, opposite to the paper outlet 14, so that the paper processing and the discharge of debris do not interfere with each other, making the space utilization in the paper storage bin 1 more reasonable. The arrangement of the positions of the paper outlet 14 and the outlet 12 makes the flow path of paper and debris smoother, reduces the risk of paper jams or equipment failures caused by the mixing of paper and debris, and improves the reliability and stability of the equipment.

[0032] More specifically, such as Figure 1 and Figure 4 As shown, a receiving groove 15 is provided inside the cavity 11. The receiving groove 15 is used to receive dropped objects. The discharge port 12 is located at the bottom of the receiving groove 15. The receiving groove 15 provides a centralized space for collecting and temporarily storing dropped objects, preventing these objects from scattering randomly inside the cavity 11 and affecting the normal operation of the equipment. The discharge port 12 is located at the bottom of the receiving groove 15. It utilizes gravity to allow dropped objects to naturally gather at the bottom of the receiving groove 15 and be smoothly discharged through the discharge port 12, reducing the risk of blockage and extending the service life of the equipment.

[0033] More specifically, such as Figure 1 and Figure 4As shown, the receiving trough 15 is provided with a guide ramp 151, which is used to guide the fallen object to the discharge outlet 12. The guide ramp 151 is designed to slope downward from the top or side of the receiving trough 15 and point towards the discharge outlet 12. Its main function is to guide the fallen object to the discharge outlet 12. The design of the guide ramp 151 utilizes the effect of gravity, so that the fallen object naturally slides down to the discharge outlet 12 under its own weight and is finally discharged from the cavity 11, reducing the residence time of the fallen object in the receiving trough 15 and improving the discharge efficiency.

[0034] More specifically, such as Figure 1 and Figure 4 As shown, the receiving groove 15 protrudes outward relative to the bottom of the cavity 11, forming a distinct recessed area at the bottom of the cavity 11. This recess is specifically designed to collect and temporarily store dropped items, allowing them to be collected more concentratedly within the receiving groove 15. This prevents the items from scattering within the cavity 11 and reduces interference with other components inside the cavity 11. The outward protrusion of the receiving groove 15 creates an independent collection area, making more rational use of the space within the cavity 11 and reducing wasted space.

[0035] More specifically, such as Figure 2 and Figure 4 As shown, the receiving groove 15 and the cavity 11 are integrally formed. The integral forming design reduces structural problems caused by loose or damaged connection points, improves the overall stability and reliability, and extends the service life of the equipment. The integral forming structure reduces the assembly steps in the manufacturing process, simplifies the production process, and reduces manufacturing costs.
