Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving electrical appliances, and more specifically, to a file processing device for archive management of industrial and commercial enterprises. Background Art

[0002] In various industrial and commercial enterprises, a large number of paper archives and other paper documents are used, such as customer information, human resources documents, contracts and agreements, market research reports, financial records and other paper documents. These paper documents need to be destroyed after they expire. At this time, in order to ensure the security of information and prevent it from being leaked, shredders will be used to shred the above-mentioned industrial and commercial enterprise archives.

[0003] The shredder is mainly composed of a shredding knife group, which includes at least two sets of knife shafts, on which are distributed a number of cutting blades. The working principle of the shredder is mainly to use a plurality of cutting blades with spacer rings to penetrate two parallel and relatively rotating knife shafts, and to use a motor and a gear device to drive the two rotating knife shafts to rotate relative to each other, so that the passing paper is shredded and cut with the help of the relative shearing cooperation of the blades on the two sets of knife shafts.

[0004] In order to ensure smooth cutting and sufficient crushing and cutting of hard paper, it is necessary to ensure close contact between the two sets of relative blades to form an effective shearing effect to ensure the crushing speed and avoid paper jams.

[0005] However, for some industrial and commercial enterprises, a large number of paper files will appear in the process of corporate activities. Therefore, a large number of documents need to be processed by shredders. Shredders are in continuous operation most of the time, and in order to increase the processing speed, the rotation speed of each knife shaft will be increased accordingly. Therefore, in this state, the relative friction between the blades forms friction heat, which causes the heat of the blades to rise. Although the rising heat will not damage the blades immediately, the blades and the corresponding structures will expand after being heated (the blades in the existing equipment are fixedly installed, so the extrusion stress generated when the metal expands is relatively large), thereby increasing the pressure between the two sets of blades that are adapted to each other, forming corresponding friction losses. After long-term use, the blades are worn, and the worn parts are mainly the blade edges. Therefore, in the later use process, if the use is interrupted (the temperature of the equipment is reduced to the initial temperature, and a small gap is formed between the worn blades), the gap formed by the wear of the blades will affect the cutting and shredding effect of the paper when it is used again, especially when a large number of waste receipts, invoices and other documents need to be processed suddenly. The paper is thinner and has better toughness, and it is more difficult to form slitting, which affects the shredding effect and even causes paper jams, resulting in shredding interruptions, affecting processing efficiency, and reducing the service life of the equipment. Summary of the invention

[0006] The present invention provides a document processing device for archive management of industrial and commercial enterprises, and aims to solve the problem that the existing paper shredder runs for a long time, causing the heat of the blade to rise and expand, increasing friction loss, affecting the shredding effect, and reducing the service life of the equipment.

Under the strong squeezing of the extrusion pieces at both ends, each group of first elastic sheets will also be relatively close, thereby ensuring that no gap is formed between the two corresponding groups of blade structures, ensuring the cutting and crushing effect, and avoiding paper jams or insufficient cutting.

[0020] 2. In the present invention, since the first elastic sheet can be squeezed, the reverse elastic force it forms on the single blade is much smaller than the strong squeezing force generated by the thermal expansion of the metal blade in the transmission scheme. Therefore, during the long-term use of the equipment, even if the blade structure heats up, the friction between the two sets of blade structures in relative contact will not be too large, and the consumption of motor drive energy will not be greatly increased, thereby achieving a certain energy-saving effect.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Refer to the instruction manual Figures 1 to 10 A document processing device for archive management of industrial and commercial enterprises includes a shredder 1, a paper feeding port 11 is arranged on the top of the shredder 1, a removable waste box 12 is arranged inside the shredder 1, a shredder mechanism is arranged below the paper feeding port 11, and the shredder mechanism includes at least two groups of shredder blade groups 2, the shredder blade group 2 includes a knife shaft 21, and multiple groups of blade structures 22 are installed on the knife shaft 21. A pad structure 23 is arranged between two adjacent groups of blade structures 22, wherein the blade structures 22 on the two groups of knife shafts 21 are arranged alternately, that is, wherein The blade edges of the blade structures 22 on one set of blade shafts 21 correspond to the blade edges of two adjacent sets of blade structures 22 on another set of blade shafts 21, so that the fitting surfaces of the two corresponding blade structures 22 form a shearing surface, thereby forming a plurality of shearing spaces, and the two sets of blade shafts 21 are driven to rotate by a driving device, and the rotation directions of the two sets of blade shafts 21 are opposite. Specifically, a driving motor is also provided in the crusher 1, and a transmission is formed between the driving motor and the two sets of blade shafts 21 through a gear set or a belt set, thereby forming a rotation drive for the blade shafts 21.

[0034] All kinds of archival documents that need to be processed in the process of archive management of industrial and commercial enterprises can be put into the paper feeding port 11, and then through the rotation of the two sets of knife shafts 21, the paper archival documents are cut into strips while moving downward. According to actual needs, a plurality of convex teeth can be set on the knife shaft 21, and the tip of the convex teeth is also set to be blade-shaped, so that while the archival documents are cut into strips, the paper strips can also be shredded with the help of the convex teeth to improve the shredding effect.

[0035] It should be noted that the above solutions are the basic structures and principles of the shredder. The start-up control of shredding and the specific shape of the blade structure 22 are all commonly used solutions in the field of shredders, and will not be explained in detail in this embodiment.

[0036] In this embodiment, each blade structure 22 and pad structure 23 are slidably mounted on the cutter shaft 21, and both ends of the cutter shaft 21 are provided with end extrusion pieces 3 for forming extrusion restrictions on all blade structures 22 and pad structures 23. A torque transmission structure is provided between the cutter shaft 21 and the pad structure 23 to facilitate driving the blade structure 22 to rotate. The torque transmission structure can use a key structure, or the cutter shaft 21 can be set to a polygonal shape to achieve torque transmission. This technology is also a commonly used installation scheme for blades in the field of paper shredders. The difference is that the end extrusion piece 3 used in this embodiment is not a fixed restriction in the traditional technology. For details, refer to the attached manual. Figures 3 to 7 The blade structure 22 includes two groups of single blades 221, and a first elastic sheet 222 (such as a rubber pad structure) is arranged between the two groups of single blades 221. The pad structure 23 includes two groups of single pads 231, and a second elastic sheet 232 (such as a rubber pad structure) is arranged between the two groups of single pads 231. The single blades 221, the first elastic sheet 222, the single pads 231 and the second elastic sheet 232 are all sleeved and installed on the blade shaft 21, and can form relative sliding with the blade shaft 21. The two groups of end extrusion pieces 3 on each blade shaft 21 are respectively arranged corresponding to the blade shaft 21 at the two ends, and the end extrusion piece 3 includes a fixed The extrusion ring 32 is slidably mounted on the cutter shaft 21, the fixing ring 31 is fixedly mounted on the cutter shaft 21 (for example, it is mounted on the cutter shaft 21 by threaded sleeve, or fixedly mounted on the cutter shaft 21 by bolts or other structures, and in order to facilitate the installation of each component, the cutter shaft 21 can be set as a multi-section docking structure for easy separate installation), the extrusion ring 32 is fitted with the blade structure 22 located at the end, and an elastic extrusion member 33 (for example, a spring) is arranged between the fixing ring 31 and the extrusion ring 32, and the elastic extrusion member 33 is used to provide an elastic force for the extrusion ring 32 to form an extrusion on the blade structure 22.

[0037] During actual use, each group of blade structures 22 and the pad structure 23 has a certain width deformation elastic force in the thickness direction due to the presence of the first elastic sheet 222 and the second elastic sheet 232. Under the action of this elastic force, the blade edges of the corresponding blade structures 22 on the two groups of blade shafts 21 can form a relatively close fit, and under the action of the elastic extrusion member 33 and the extrusion ring 32, all the blade structures 22 tend to move inward. When the equipment is used for a long time, when the single blade 221 as a metal structure forms thermal expansion, the first elastic sheet 222 can be squeezed first, thereby reducing the deformation extrusion force caused by thermal expansion between the two groups of blade structures 22 in contact with each other, reducing the wear on the blade edge of the blade structure 22, and increasing the service life of the equipment.

[0038] Compared with the prior art, when the blades expand and the friction between them increases, the relative resistance between the two sets of blade shafts increases, the required motor power increases, and thus the energy consumption of the shredder increases. In the present invention, since the first elastic sheet 222 can be squeezed, the reverse elastic force it forms on the single blade 221 is much smaller than the strong squeezing force generated by the thermal expansion of the metal blade in the transmission scheme. Therefore, during the long-term use of the equipment, even if the blade structure 22 heats up, the friction between the two sets of blade structures 22 in relative contact will not be too large, and thus the consumption of motor drive energy will not be greatly increased, thereby achieving a certain energy-saving effect (in addition, the present embodiment can also set a corresponding sensor structure according to the energy-saving scheme in the prior art to sense the start and end of the delivery of archive documents, so as to stop the equipment in time after the paper shredding is completed, thereby further improving the energy-saving effect).

[0039] At the same time, even if a single blade 221 is worn out after long-term use, under the strong squeezing of the extrusion pieces 3 at both ends (the stiffness coefficient of the elastic extrusion piece 33 is higher than the stiffness coefficient of each first elastic piece 222 and the second elastic piece 232, that is, each first elastic piece 222 and the second elastic piece 232 is easier to deform than the elastic extrusion piece 33), each group of first elastic pieces 222 will also be relatively close to each other, thereby ensuring that no gap is formed between the two corresponding groups of blade structures 22, ensuring the cutting and crushing effect, and avoiding paper jams or insufficient cutting when suddenly crushing thinner and more tough paper files such as invoices.

[0040] It should be noted that, even if the blade of the processing equipment provided in this embodiment is worn, there is no need to manually replace the blade or scrap it, thereby increasing the service life of the equipment, reducing material waste, and further responding to the call for energy conservation. Moreover, in the processing equipment provided in this embodiment, when the blade is worn, the extrusion ring 32 squeezes each group of single blades 221, so that the thickness of each group of blade structures 22 is relatively thin, which can further reduce the crushing size and improve the crushing effect. Moreover, the processing equipment provided in this embodiment, in addition to being adaptable to industrial and commercial enterprise activities, can also be used as an energy-saving household appliance for use by families in need.

[0041] Furthermore, although the elastic extrusion member 33 can effectively extrude the single blade 221, since the elastic extrusion member 33 can be reversely compressed, when thick and strong paper files are crushed, the blade structure 22 may be reversely extruded outward. Therefore, in order to further avoid paper jams, the present embodiment also provides the following solutions. For details, refer to the attached manual. Figure 5 and Figure 6 A check assembly is provided between the extrusion ring 32 and the knife shaft 21, and the check assembly includes a check pressure block 34. A plurality of mounting grooves are provided at the position of the extrusion ring 32 corresponding to the knife shaft 21. The check pressure block 34 is movably installed in the mounting groove, and an oblique connecting rod 35 is rotatably connected to the check pressure block 34. An end of the oblique connecting rod 35 away from the check pressure block 34 is rotatably installed in the extrusion ring 32. An end of the oblique connecting rod 35 away from the axis of the knife shaft 21 is inclined in a direction close to the blade structure 22, and an elastic ball 36 is provided between the check pressure block 34 and the mounting groove of the knife shaft 21. The elastic ball 36 is used to provide an elastic force for the check pressure block 34 to approach the knife shaft 21.

[0042] In actual use, when the elastic extrusion member 33 pushes the extrusion ring 32 to move and extrude toward the blade structure 22, the oblique connecting rod 35 is affected by the structure of the oblique connecting rod 35 and forms a pulling force on the anti-return pressure block 34, so that it can move smoothly. If an unexpected situation causes the blade structure 22 to form a reverse extrusion on the extrusion ring 32, at this time, the oblique connecting rod 35 forms a pushing tendency on the anti-return pressure block 34. Since the oblique connecting rod 35 is inclined, when the oblique connecting rod 35 forms a pushing tendency on the anti-return pressure block 34, it will form an extrusion on the anti-return pressure block 34 toward the blade shaft 21, thereby increasing the friction resistance between the anti-return pressure block 34 and the blade shaft 21, thereby realizing the anti-return function.

[0043] It should be noted that this embodiment is not limited to the above-mentioned check structure, and other structures that can achieve relative check function are also acceptable. In order to install and disassemble, the extrusion ring 32 can be set as two sets of half-ring structures for installation, or other compatible and easy-to-disassemble structures can be used.

[0044] Furthermore, since the actual shearing surface area of ​​each set of blade structures 22 is limited, even if wear occurs, it is only in the area near the edge. Therefore, in order to avoid irregular wear, refer to the attached manual. Figure 7 In this embodiment, a shearing surface of the single blade 221 for realizing the cutting function is provided with a material reduction groove 223, so as to avoid the formation of a stepped structure due to wear. Even if it is worn, the loss surface is relatively uniform, ensuring that the cutting edge of the single blade 221 is relatively sharp after wear.

[0045] In addition, since the original integrated blade structure 22 is divided into two, in order to improve the torque transmission effect of the blade shaft 21 on the single blade 221, this embodiment also provides the following technical solutions. Figure 7 and 8 A plurality of radial guide grooves 224 are arranged on one side of the first elastic sheet 222 corresponding to the single blade 221, and a radial ridge 225 is fixedly connected to the position of the single blade 221 corresponding to the radial guide groove 224. The radial ridge 225 is embedded in the radial guide groove 224, so that a certain torque can be transmitted between the two opposite single blades 221 through the first elastic sheet 222. At the same time, a similar structure can be arranged between the single pad 231 and the single blade 221 and between the single pad 231 and the second elastic sheet 232, so as to further improve the stability of the operation of the blade structure 22.

[0046] Among them, the thickness of the radial ridge 225 at one end away from the center of the single blade 221 gradually increases, thereby forming a slope structure, and the radial guide groove 224 and the slope structure of the radial ridge 225 are adapted to each other. At the same time, grease is arranged between the single blade 221 and the first elastic sheet 222. In particular, with the existence of the radial guide groove 224, relatively more grease can be stored inside. Therefore, in actual use, if the single blade 221 expands due to heat and forms a certain extrusion on the first elastic sheet 222, under the guidance of the radial ridge 225 and the lubrication of the lubricating oil, the first elastic sheet 222 preferentially produces an outward expansion deformation to reduce the reverse extrusion stress of the first elastic sheet 222 on the single blade 221.

[0047] In addition to the above-mentioned solution for protecting the blade structure 22, this embodiment also provides the following solution. Figures 3 to 5The blade shaft 21 is a hollow structure, and both ends of the blade shaft 21 extend out of the grinder 1. The inner cavity of the blade shaft 21 is arranged to penetrate horizontally. A plurality of sets of heat conductive sheets 211 are installed in the inner cavity of the blade shaft 21. The heat conductive sheets 211 are arranged in a fan-blade-shaped structure. Therefore, in actual use, when the blade shaft 21 rotates, an airflow can be formed inside the blade shaft 21. The airflow cooperates with the heat conduction of the single blade 221 to form a certain heat dissipation effect on the blade shaft 21 and the single blade 221, so as to reduce the temperature rise of the blade structure 22.

[0048] Furthermore, this embodiment also adopts the following technical solutions to improve the heat dissipation effect of the blade structure 22, refer to the attached manual Figures 9 and 10 Specifically, a flow guide 4 is arranged below the two groups of shredding knife groups 2. The flow guide 4 is a cover structure, which is fixedly installed in the pulverizer 1. A flow guide fan 41 is rotatably installed inside the flow guide 4. A filter baffle 42 is arranged on the top of the flow guide 4. The two sides of the filter baffle 42 are arranged to be tilted downward. The middle part of the filter baffle 42 corresponds to the area between the two groups of shredding knife groups 2. The flow guide fan 41 is driven to rotate by the automatic driving component and forms a downward airflow, so that in actual use, a downward airflow (through the paper feeding port 11, and from the outside to the inside) can be formed between the two groups of shredding knife groups 2. Firstly, the airflow can form a certain heat dissipation effect on the blade structure 22, secondly, the downward flow effect of the waste paper after shredding can be enhanced, and thirdly, a certain drying effect can be formed on the surface of the blade structure 22 to avoid rust and other damage to the surface of the blade structure 22 caused by the long-term presence of moisture when processing wet files.

[0049] For further information, please refer to the attached manual. Fig.10 The automatic drive component includes a transfer drive shaft 43, which is rotatably installed inside the drain device 4. The transfer drive shaft 43 is matched with the drainage fan 41 through a bevel gear assembly. The transfer drive shaft 43 is matched with the drive motor for driving the knife shaft 21 to rotate through a gear transmission assembly or a belt transmission assembly, thereby realizing synchronous driving of the drainage fan 41 without the need for an additional drive source to avoid energy waste.

[0050] A docking tube 44 is fixedly connected to the bottom of the drain device 4, and an air blowing pipe 121 is fixedly installed inside the waste box 12. When the waste box 12 is installed inside the crusher 1, the docking tube 44 is docked with the air blowing pipe 121. For example, the matching ends of the docking tube 44 and the air blowing pipe 121 are set to a cut shape, or other automatic docking structures are set, and a plurality of dispersion pipes 122 are fixedly installed on the bottom end of the air blowing pipe 121. The dispersion pipes 122 are set upward, and an air outlet window 13 is set on the side wall of the crusher 1.

[0051] It should be noted that although the rotation of the drainage fan 41 can form a downward airflow, due to the presence of the filter baffle 42, the crushed paper fragments will not directly enter the drain device 4, but will gradually fall from both sides into the waste bin 12. The downward airflow formed by the drainage fan 41 will be blown upward from the dispersion pipe 122, so that the paper fragments entering the waste bin 12 will fly in disorder, thereby achieving a dispersion effect on the paper fragments that enter within a certain period of time, increasing the difficulty of restoring the paper fragments, and thus improving the confidentiality effect.

[0052] In addition, in order to further improve the confidentiality of equipment processing, the present embodiment also provides the following technical solutions: a collecting box 14 is also provided inside the shredder 1, and the collecting box 14 is also a pull-out structure, so as to form a detachable installation; a collecting channel 15 is formed between the waste box 12 and the shredder 1, and the collecting channel 15 is provided corresponding to the collecting box 14, and the air outlet window 13 is provided above the collecting channel 15, and a filter 131 (such as a filter screen to prevent paper fragments from flying out) is provided in the air outlet window 13; a guide plate 16 is provided at a position corresponding to the air outlet window 13 in the shredder 1, and the guide plate 16 extends to the top of the inner cavity of the waste box 12, thereby forming an inverted U-shaped channel between the top of one side of the inner cavity of the waste box 12 and the collecting channel 15, and the air outlet window 13 is located at the top of the inverted U-shaped channel.

[0053] It should be noted that the above airflow does not need to be too strong to prevent the paper fragments from being adsorbed on the filter baffle 42 and not easily falling off. In actual design, the inclination angles of the filter baffle 42 and the filter 131 can be set according to needs to avoid blockage.

[0054] In actual use, since the paper fragments falling from both sides of the filter baffle 42 float in disorder and the dispersion pipe 122 forms an upward blowing effect, some paper fragments at the guide plate 16 will flow with the outlet air flow at the outlet window 13, and under the obstruction of the filter 131, they will eventually fall into the collection box 14 from the collection channel 15. Since the above phenomenon is uncertain, that is, the number and time of paper fragments entering the collection box 14 from the collection channel 15 are not fixed, after the same document is shredded, uncertain paper fragments will leave the waste bin 12. In other words, even if the shredded paper fragments are collected, there will be uncertain data missing, which further increases the difficulty of restoration and improves the confidentiality of the equipment.

[0055] It should be noted that the collection box 14 can be designed as a concealed structure that is not easily noticed, and the shredded paper pieces collected therein can be handled separately, or a soaking liquid can be provided in the collection box 14, and the soaking liquid is used to destroy the shredded paper pieces, such as water, alcohol, and corrosive chemical reagents, so that the shredded paper pieces falling into the collection box 14 will be destroyed immediately.
