Description

Technical Field

[0001] The present invention relates to the technical field of paper shredders, and in particular to an intelligent confidentiality paper shredder. Background Art

[0002] A shredder is a device that breaks down confidential documents, bank cards, CDs, and other items into small pieces, such as granules, segments, foam, strips, or filaments. Existing shredders typically consist of a machine body, a shredder assembly and motor located in the upper portion of the machine body, and a scrap collection bucket located within the machine body below the shredder assembly. After being shredded by the shredder assembly, waste paper, confidential documents, bank cards, and CDs fall through the shredder discharge port into the scrap collection bucket. When the machine's full-scratch alarm sounds or the scrap collection bucket is found to be full through the inspection window, the scrap collection bucket is manually pulled out and the scraps inside are emptied.

[0003] Currently, all shredders on the market can shred private and confidential documents, achieving a certain degree of confidentiality, but they still have many drawbacks:

[0004] 1. The scraps in the scrap bin need to be cleaned manually, and the scraps flying around when dumping affect the surrounding environment.

[0005] 2. There is a large gap between the shredded paper discharge port and the shredded paper collection bucket, which makes it easy for shredded paper to splash or float between the outside of the shredded paper collection bucket and the interlayer of the machine body, causing the shredded paper to be messy and difficult to remove;

[0006] 3. Since the broken paper scraps contain static electricity, a large amount of paper scraps will be adsorbed on the wall of the plastic scrap collection bucket, making it difficult to remove;

[0007] 4. After dumping, the exposed scraps of paper are more likely to be discovered or recovered, leading to the theft of important information;

[0008] The above-mentioned drawbacks make many people less interested in paper shredders, preferring to use the original methods of tearing by hand, burning or throwing paper down the toilet. Therefore, the industry's research and development direction is also to solve the above-mentioned similar problems.

[0009] For example, the Chinese patent application number CN201921422009.6 is a paper shredder for audit confidentiality documents, whose structure includes rollers, a body, an electric control board, a cover, a paper feed, a shredder disc, and a chip remover. The top of the body is provided with a recessed cover, the bottom of the paper feed is provided with an integrated shredder disc, the bottom of the body is provided with a roller that can touch the ground and rotate, the body is provided with an embedded electric control board, the electric control board is electrically connected to the shredder disc through a wire, and a chip remover is provided in the empty slot of the body.

[0010] While the above solution pulls out the dust collection chamber via a baffle when cleaning waste paper, allowing the guide beads on the rear wall of the partition to move outward along the inner wall of the machine body due to friction, allowing internal dust removal and external operation to clean waste paper, significantly reducing air pollution from waste debris and improving the practicality of the machine, it still does not solve the problems of static electricity in the paper scraps, which makes them difficult to remove, and the risk of the paper scraps being recovered after being dumped. Summary of the Invention

[0011] In response to the problem in the prior art mentioned in the background technology that the need for flow measurement makes it difficult to ensure the stability and uniformity of the gas turbine test bench intake, the present invention provides an intelligent confidential shredder with automatic bag and sealing functions, which makes operation and cleaning simple and practical, and has stronger confidentiality, and is very suitable for user needs.

[0012] In order to achieve the above object, the present invention adopts the following technical solutions:

[0013] An intelligent confidentiality shredder includes a device body, characterized in that the device body includes a shredding module and a shredded paper bag arrangement module disposed below the shredding module. The shredded paper bag arrangement module includes a shredded paper bag storage bin, and an automatic sealing module is disposed on the side of the shredded paper bag storage bin. The shredded paper bag arrangement module releases and spreads shredded paper bags provided by the shredded paper bag storage bin and receives shredded paper processed by the shredding module. The automatic sealing module seals the shredded paper bags filled with shredded paper. The automatic sealing module packs the shredded paper bags filled with shredded paper, thereby preventing the problem of shredded paper being attracted by static electricity and difficult to clean inside the shredder. Furthermore, after packing, shredded paper can be centrally processed, eliminating the risk of shredded paper being lost and subsequently recovered. This achieves two goals at once and completely solves the technical problem raised by this application.

[0014] Furthermore, the shredding module includes a shredding blade assembly, a shredding guide slot extending into the shredded paper bag, and a full-chip detector located on the side of the shredding guide slot. The shredding guide slot is used to guide paper scraps, ensuring that they enter the shredded paper bag completely and do not stick to other areas inside or outside the shredded paper box, thereby achieving efficient storage of paper scraps.

[0015] Preferably, the shredded paper packing bag storage compartment includes a storage box positioned below the shredding module. The storage box comprises an inner box and an outer box that are fastened together, forming an annular cavity between the inner and outer boxes for accommodating the shredded paper packing bags. A connecting seam is provided on the side of the annular cavity adjacent to the interior of the device body. The automatic sealing module is positioned outside the storage box and comprises a dual-beam closing mechanism and a sealer positioned at the working end of the dual-beam closing mechanism. Unused shredded paper packing bags stored in the storage box are released outward through the connecting seam, and the sealer seals the opening of the shredded paper packing bag once the dual-beam closing mechanism has closed it, thereby achieving automatic packaging of the shredded paper packing bags and facilitating direct removal and disposal by the user.

[0016] Preferably, the double-beam closing mechanism includes a transverse closing beam and a longitudinal closing beam that are vertically cross-distributed. A transverse motor is provided at the end of the transverse closing beam, and a longitudinal motor is provided at the end of the longitudinal closing beam. The sealing device is an electric heating head. The longitudinal motor and the transverse motor respectively drive the transverse closing beam and the longitudinal closing beam to move toward the electric heating head to perform sealing movement. The transverse motor and the longitudinal motor are respectively connected to the transverse closing beam and the longitudinal closing beam by a transmission belt to ensure synchronous operation under the command of the control module, so that the transverse closing beam and the longitudinal closing beam both move toward the electric heating head, and finally complete the closing of the shredded paper packaging bag in front of the electric heating head.

[0017] Preferably, the device body further comprises a storage box and a drawer mechanism inserted into the storage box, the drawer mechanism comprising a front panel with a mounting bracket provided on the front panel, the shredded paper packing bag placement module comprising a shredded paper box disposed between the mounting bracket and the front panel, and the front panel with a handle provided on the front panel. The drawer mechanism is used to accommodate the shredded paper box, and when the shredded paper packing bag is full, the drawer mechanism and the shredded paper box can be pulled out of the device body by pulling the handle, thereby facilitating the user to remove the full shredded paper packing bag.

[0018] Preferably, the fixing frame is provided with a lifting mechanism, comprising a main board located away from the front panel and side panels disposed on either side of the main board. The lifting mechanism comprises a first electromagnet mounted on the main board, a pull rod disposed on the top of the first electromagnet, and two seesaws parallel to the side panels disposed on either side of the pull rod. The middle portion of the seesaw is hinged to the side panels, and a push rod is disposed on the end of the seesaw away from the pull rod, the top of the push rod being connected to the shredded paper box. The lifting mechanism utilizes the principle of leverage to lift the shredded paper box, facilitating the rapid formation of negative pressure during intelligent packaging operations.

[0019] Preferably, a negative pressure device is provided at the bottom of the shredder box. The negative pressure device includes an impeller and a motor for driving the impeller, which is mounted on the shredder box. A shredded paper packing bag sensor is provided below the impeller. The negative pressure device applies negative pressure to the shredder box, allowing the shredded paper packing bags to be fully spread out and arranged, ensuring that the space within the shredded paper packing bags is effectively utilized. The shredded paper packing bag sensor works in conjunction with the impeller and stops applying negative pressure upon sensing that the shredded paper packing bags are blocking the shredded paper packing bags, indicating that the work is complete.

[0020] Preferably, the fixing frame is provided with a release mechanism, which includes a second electromagnet and a top seat provided on the main board; the second electromagnet includes a pull rod, on which a lock hook is hingedly provided; a top block is movably provided in the top seat, and a lock shaft is provided on the side of the top block close to the second electromagnet; a top spring is provided on the top block, and a top plate is provided on the side plate corresponding to the top block, and the top block abuts against the top plate; the lock hook is connected to the lock shaft hanging card, and when the second electromagnet controls the lock hook to disengage from the lock shaft, the top block collides with the fuselage. The release mechanism is used to eject the pull-out mechanism from the fuselage after the shredded paper packing bag is filled and sealed, realizing intelligent use. The user does not need to frequently check whether the shredded paper packing bag needs to be replaced. When it is full, it will automatically pop up to remind the user to replace it, thereby improving the user experience.

[0021] The lock hook is equipped with a tension spring at its tail end, with the end of the tension spring away from the lock hook connected to the top seat. The tension spring is used to assist in resetting the lock hook, ensuring that after the release mechanism operates once to push out the drawer mechanism and the shredded paper box, it can automatically reset after the user removes the shredded paper bag and pushes it back into the drawer mechanism.

[0022] The outer box has an oblong through-hole on its side. A bag-empty detector is located within the oblong through-hole to detect when the shredded paper packing bags are depleted, allowing for timely replacement. The bag-empty detector detects the use of the shredded paper packing bags. When the shredded paper packing bags in the storage box are depleted, the shredded paper packing bag placement process automatically terminates and the process resumes after the storage box is replaced.

[0023] The rear of the automatic sealing module is provided with a rotating frame, which is fixed to the device body and hinged to the automatic sealing module via a damping shaft. The automatic sealing module is hinged to the body of the device through the rotating frame, and when tilted downward, it is convenient for the user to replace the storage box.

[0024] Therefore, the present invention has the following beneficial effects:

[0025] 1) A guide function has been added to the falling shredded paper, which can ensure that all shredded paper falls into the shredded paper packing bag at the bottom, leaving no shredded paper residue inside or outside the shredded paper box;

[0026] 2) The use of the shredded paper bag arrangement module makes the shredder more intelligent;

[0027] 3) The automatic sealing module automatically packs the shredded paper into bags, enhancing the confidentiality of private documents;

[0028] 4) The downward rotation and opening of the automatic sealing module and the cooperation of the pull-out mechanism make it easy to replace the shredded paper packaging bags after they are used up. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and are not to be construed as limiting the present invention.

[0054] Example 1

[0055] The present invention is an intelligent confidentiality shredder, see Figure 1 、 Figure 6 , including five parts: shredding module, shredded paper packaging bag arrangement module, automatic sealing module 3, release mechanism 4 and pulling mechanism 5.

[0056] The shredder module consists of an upper head and a lower body. The upper head houses the shredder blade assembly 1a, a drive assembly 1b, and a full-chip detector 1c. Confidential documents and materials are placed through the upper inlet 1d, where they are shredded by the shredder blade assembly 1a and then discharged through the chip discharge port below. A shredder guide slot 1e is located below the chip discharge port. Figure 1 、 Figure 2 The shredded paper guide trough 1e is a hollow square tube structure that expands at the top and contracts at the bottom. The upper opening extends into the interior of the chip discharge port, while the lower opening is contracted at the middle through-hole of the storage box of the shredded paper packing bag arrangement module. The shredded paper guide trough 1e guides the shredded paper discharged from the chip discharge port into the shredded paper packing bag below it for collection. Its connecting flange 1e1 fits under the shredded paper chip discharge port. A connecting seam 1e2 is left between the connecting flange 1e1 and the rear side panel. The fullness detector 1c, installed at a certain angle inside the shredder head, detects the accumulation of shredded paper in the shredded paper packing bag through this connecting seam 1e2 and promptly feeds back to the host for timely processing. The upper part of the machine body is connected to the lower part of the machine head, and the front is completely open. The shredded paper packing bag arrangement module, automatic sealing module 3, release mechanism 4 and pulling mechanism 5 are all located within its internal space.

[0057] The upper part of the automatic sealing module 3 is designed with a hollow groove, in which the accommodating box 2a of the shredded paper packing bag arrangement module is installed. Figure 3 、 Figure 4 Inside the housing 3a and bottom cover 3b of the automatic sealing module 3 are arranged a depth motor 3c, a transverse motor 3d, a longitudinal gathering beam 3e, a transverse gathering beam 3f, a rotating bracket 3g, an electric heating head 3h, an insulating pad 3i, a damping shaft 3j, four sets of in-position switches and four sets of detectors 3k. The depth motor 3c and the transverse motor 3d respectively drive the longitudinal gathering beam 3e and the transverse gathering beam 3f through a belt drive to perform longitudinal movement forward and backward and transverse movement left and right to gradually gather the shredded paper packing bag 2a3 from the opening to the sealing. The four sets of in-position switches respectively control the original position and sealing position of the longitudinal gathering beam 3e and the transverse gathering beam 3f. The electric heating head 3h arranged at the sealing position performs heat-melt sealing and melting on the plastic shredded paper packing bag 2c. The insulating pad 3i installed on the transverse gathering beam 3f at the corresponding position of the electric heating head 3h provides thermal insulation protection for the transverse gathering beam 3f to prevent deformation. Four sets of sensors 3k are positioned within the sidewalls of the container 2a, facing the four oblong through-holes 2a4. They detect the use of the shredded paper packaging bags 2a3 within the container 2a. A rotating frame 3g at the rear of the automatic sealing module 3 is fixed to the machine body and hinged to the automatic sealing module 3 via a damping shaft 3i. A steel buckle 3m is designed on the top front of the automatic sealing module 3 to fasten to the machine head.

[0058] The drawer mechanism 5 is composed of a front panel 5a, a fixing frame 5b and drawer rails on both sides. Figure 5 A spring handle 5c is installed on the upper portion of the front panel 5a to facilitate pulling out the drawer mechanism 5.

[0059] The shredded paper packing bag arrangement module is divided into two parts, the upper part is the receiving box 2a, which is arranged below the shredded paper guide groove 1e and installed in the upper groove of the automatic sealing module 3. Figure 1 、 Figure 3 The lower part is composed of shredded paper box 2b, lifting mechanism 2c, air suction device 2d and shredded paper packing bag sensor 2e, all of which are installed on the pulling mechanism 5 and then enter and exit the inner cavity of the machine body. Figure 6 .

[0060] The upper receiving box 2a of the shredded paper packing bag arrangement module is composed of an inner box 2a1, an outer box 2a2 and shredded paper packing bags 2a3. Figure 7 . The inner box 2a1 and the outer box 2a2 are connected by snap fastening to form one inside and one outside, one bottom and one top, with an annular cavity formed in the middle. After the inner box 2a1 and the outer box 2a2 are connected, the overall appearance is a rectangular ring, and the middle through hole is a falling channel for the shredded paper. The upper part of the inner ring of the annular cavity of the inner box 2a1 and the outer box 2a2 forms an annular connecting seam. The shredded paper packing bag 2a3 is a continuous cylindrical structure of a certain length, open at both ends, and made of plastic. It is continuous within the length range, has no breakpoints, and no seals. It is stacked into multiple layers and hollow rings and placed in the above-mentioned annular cavity. One end of the opening of the shredded paper packing bag 2a3 is placed inside the annular cavity, and the other end extends out of the annular connecting seam and is sealed to the middle through hole of the accommodating box 2a. The front and rear outer walls of the outer box 2a2 are respectively designed with two oblong through holes 2a4 that pass directly through the annular cavity.

[0061] The shredder box 2b is a barrel-shaped structure with an upward opening. Figure 8 , leaving a gap with the bottom of the automatic sealing module 3. Six ear supports are arranged on the side walls of the barrel mouth. Four of these ear supports rest on the upper flange of the fixed frame of the pull-out mechanism 5, and the two middle ear supports on the top rod flange of the lifting mechanism 2c. A grille hole is designed at a low position on the rear of the shredded paper box 2b, and a suction device 2d is installed on its exterior.

[0062] The lifting mechanism 2c is arranged on the left and right sides and the rear of the pulling mechanism 5, and is composed of a first electromagnet 2c1, a pull rod 2c2, two left and right rockers 2c3, two left and right push rods 2c4 and a transition piece 2c5. Figure 9The first electromagnet 2c1 is mounted to the rear of the drawer mechanism 5 via an electromagnet base 2c6. One end of the transition piece 2c5 is hinged to the iron core of the first electromagnet 2c1, and the other end is hinged to the middle of the pull rod 2c2. The two axial ends of the pull rod 2c2 are fixed to the tails of the left and right rockers 2c3. The support hole of each rocker 2c3 is hinged to the protruding columns on both sides of the drawer mechanism 5's fixed frame 5b. The other end hole is hinged to the lower axial sections of the left and right push rods 2c4. After the lower axial sections of the push rods 2c4 pass through the upper through-holes on both sides of the drawer mechanism 5's fixed frame 5b, their flange sections rest on the upper flange of the upper fixed frame 5b. The flanges of the push rods 2c4 support the left and right ear supports of the shredder box 2b, and the upper axial sections are positioned in the ear support holes. A tension spring is attached to each of the left and right rockers 2c3, hanging from the fixed frame 5b, which is a U-shaped plate.

[0063] like Figure 10 The suction device 2d is mounted outside the grille at the lower rear end of the shredder box 2b. It provides axial airflow and lateral airflow. It consists of a DC motor 2d1, a wheel base 2d2, an impeller 2d3, a cover 2d4, and fixing screws. The shredded paper bagging sensor 2e is located at the lower end of the shredder box 2b, below the suction device 2d. It determines whether the shredded paper bagging process is complete during automatic bagging.

[0064] Example 2

[0065] In this embodiment, a release mechanism is disclosed for automatically pushing out the shredded paper box after the shredded paper packing bag is full and packed to remind the user to remove it. The release mechanism 4 is located between the rear wall of the fixing frame 5b of the pulling mechanism 5 and the rear wall of the fuselage, and is installed at one end of the inner side of the rear wall of the fuselage. Figure 11 , including a second electromagnet 4a, a pull rod 4b, a lock hook 4c, an electromagnet seat 4d, a lock shaft 4e, a tension spring 4f, a top block 4g, a top seat 4h and a top spring 4i. The second electromagnet 4a is fixed to the inner side of the rear wall of the machine body through the flange of the electromagnet seat 4d. The iron core of the second electromagnet 4a is hinged to the pull rod 4b through an elastic pin and the travel is limited by the long hole on the electromagnet seat 4d. A sleeve and a pin are fixed on the lock hook 4c, which are respectively hinged to a fixed pin on the electromagnet seat 4d and the pull rod 4b. The tension spring 4f is respectively hung on a small hole in the lock hook 4c and another hanging pin on the electromagnet seat 4d. The lock shaft 4e is fixed to the rear wall of the fixed frame 5b in the pulling mechanism 5 through a U-shaped block. Under normal circumstances, it is hooked by the hook part of the lock hook 4c. The top seat 4h connected to the plane flange of the electromagnet seat 4d is equipped with a top block 4g. The head of the top block is pushed out of the middle hole of the top seat 4 by the top spring 4i for a certain length and is then limited by the top seat 4.

[0066] Example 3

[0067] In this embodiment, the structure in the above embodiment completes its actions and functions through intelligentization, wherein the execution process of bagging operation, paper shredding operation and sealing operation is as follows:

[0068] Bag operation execution process, see Figure 9 、 12 In the shredder, when the bagging command is issued, the first electromagnet 2c1 in the lifting mechanism 2c is energized and attracted, and the push rod 2c4 lifts the shredded paper box 2b and aligns it with the automated bag sealing module 3. The suction device 2d then activates, creating a large negative pressure in the inner cavity of the shredded paper box 2b, attracting the undeployed shredded paper packing bags 2a3 to the inner wall of the shredded paper box 2b. At this point, the shredded paper packing bags 2a3 take on the shape of a cavity with a hollow interior and an open top, and the shredded paper packing bag sensor 2e is blocked, indicating that the bagging is successful. After the bagging is successful, the first electromagnet 2c1 is de-energized, the shredded paper box 2b falls back, and the shredder can begin shredding. When the bag empty detector 3k detects that the shredded paper packing bags 2a3 are exhausted, the bagging process automatically terminates, and the storage box 2a is replaced and the bagging is resumed.

[0069] For the paper shredding process, see Figure 13 After paper A enters the shredder through the shredding port 1d, it is shredded into shredded paper scraps B by the shredding blade assembly 1a. The shredded paper scraps then flow through the shredding guide slots 1e and fall to the bottom of the shredded paper packing bag 2a3 filled with shredded paper boxes 2b. The shredded paper scraps are gradually stacked. When the stacked shredded paper scraps reach a certain height and are detected by the full-scrap detector 1c, the shredder will sound a full-scrap alarm and stop working.

[0070] The sealing process: After the shredder stops operating after the full-shred alarm sounds, the sealing command is initiated. The depth motor 3c of the automatic sealing module 3 first activates, driving the longitudinal retraction beam 3e to translate to more than half its depth toward the sealing side. Then, the transverse motor 3d activates, driving the transverse retraction beam 3f to translate to more than half its depth toward the sealing position. Finally, the depth motor 3c and transverse motor 3d simultaneously drive the longitudinal retraction beam 3e and transverse retraction beam 3f to translate to the electric heating head 3h to seal and fuse. After the fuse is blown, the depth motor 3c and transverse motor 3d simultaneously drive the longitudinal retraction beam 3e and transverse retraction beam 3f to return to their original positions. At this point, the shredded paper bag filled with shredded paper is separated from the upper portion free of shredded paper, and both are now sealed. As the longitudinal and transverse retraction beams 3e and 3f on the outer walls of the shredded paper bag 2a3 translate, the outer walls of the bag 2a3, now filled with shredded paper, move with them. This causes the opening of the bag 2a3 to close, ultimately sealing and fusing. After the longitudinal and transverse retraction beams 3e and 3f return to their original positions, the second electromagnet 4a of the release mechanism 4 engages, the locking hook 4c releases the locking shaft 4e, and the push block 4g, acting under the action of the push spring 4i, ejects the pull-out mechanism 5 a short distance out of the shredder's internal cavity 1. After the operator fully extends the pull-out mechanism 5, they remove the shredded paper bag 2a3 and push it back into the shredder's cavity.

[0071] In addition to the above-mentioned embodiments, within the scope disclosed in the claims and description of the present invention, the technical features of the present invention can be reselected and combined to form new embodiments. These can be achieved by those skilled in the art without creative work. Therefore, these embodiments that are not described in detail in the present invention should also be regarded as specific embodiments of the present invention and within the scope of protection of the present invention.
