Description

Technical Field

[0001] The present invention relates to the technical field of paper recycling devices, and in particular to an Internet of Things-based paper recycling device. Background Art

[0002] A paper shredder consists of a set of rotating blades, a paper comb, and a driving motor. Paper is fed into the middle of the interlocking blades and is cut into many small pieces of paper to achieve the purpose of confidentiality. The shredding method refers to the shape of the paper after it is shredded by the shredder blades when the paper passes through the paper recycling device. According to the composition of the shredder blades, the existing shredding methods are: shredded, granular, segmented, foamed, strip-shaped, filamentous, etc.

[0003] Common paper recycling devices in the prior art do not have the function of the Internet of Things and are only used as an office equipment, with low equipment utilization rate and low recycling rate of shredded waste paper.

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0040] A waste paper recycling system for an Internet - of - Things paper recycling device, as Figure 1 shown, includes a cloud server and multiple paper recycling devices communicatively connected to the cloud server. The connection between the paper recycling device and the cloud server is as Figure 2As shown, a control unit is provided inside the paper recycling device. The control unit is used to control the operation of the weighing unit, the paper shredding unit, and the pressing unit, and receive the weight data obtained by the weighing unit and the volume data obtained by the pressing unit. The control unit controls the user information collection unit to generate corresponding two-dimensional codes and collect user image data. The control unit sends the weight data, volume data, and user image data to the cloud server through the communication unit. The cloud server receives the corresponding data, communicates with the user's mobile terminal, collects the user's personal information data, and merges the user's personal information data and user image data to establish a user profile through the user management unit. The cloud server receives the volume data and sends a prompt message to the administrator through the paper shredding management unit. The cloud server receives the weight data of the waste paper, generates settlement information through the settlement unit, and then binds the settlement information to the user profile. The settlement information can be either an amount or points.

[0041] The user information collection unit is respectively connected to the control unit and the human-computer interaction unit. The human-computer interaction unit collects user image information through the image collection unit and generates two-dimensional codes through the two-dimensional code generator. After the user scans the two-dimensional code, the cloud server establishes a connection with the mobile terminal to collect the user's personal information. The user information collection unit mainly transmits the user image information to the control unit.

[0042] After the user enters personal information, the paper recycling device will open the recycling port. After the user delivers waste paper into the recycling port, the waste paper enters the weighing unit through the conveyor belt for weighing, then is shredded by the paper shredding unit, and finally is pressed by the pressing unit in the recycling bin. The weighing unit records the weight data, and the pressing unit records the volume data in the recycling bin, and transmits them to the cloud server through the control unit and the communication unit.

[0043] The human-computer interaction unit is mainly used for the user to query points or amounts on the paper recycling device and provide goods for point redemption. The cloud server is used to store the user's personal information, monitor the relevant information of all paper recycling devices in real time, and prompt the administrator to recycle the shredded paper in time. The drive system of the paper recycling device can be selected from an electric system, a mechanical system, or a hydraulic system. Considering the noise limit in the community, the hydraulic system is preferably used for driving.

[0044] The cloud server sends a prompt message to the management according to the volume data in the recycling bin. After receiving the prompt message, the administrator will recycle the pressed paper scraps in the recycling bin. However, there may be other substances in the waste paper delivered by users, such as moisture. To avoid other substances remaining in the paper recycling device for a long time, a detection unit, such as a moisture detector, is also set in the paper recycling device. The control unit receives the detection information of the detector and sends it to the cloud server. The cloud server sends a maintenance message to the corresponding administrator to ensure the subsequent maintenance of the paper recycling device. At the same time, the cloud server can trace back the user information related to sundries in reverse to prompt the user to ensure that the waste paper put in does not contain other substances.

[0045] The paper recycling device in the present invention is mainly used for waste paper recycling in communities. A single administrator is responsible for the paper recycling devices in all communities in the area. To prevent the loss of the paper recycling device or facilitate the management of the administrator, a positioning unit, such as a GPS locator, is also set in the paper recycling device. At the same time, considering that the paper recycling device may be in an outdoor environment, to increase its service life, corresponding moisture-proof, electricity-proof and anti-theft settings can be considered for the paper recycling device.

[0046] A waste paper recycling method based on an Internet of Things paper recycling device, as Figure 3 shown, includes the following steps:

[0047] S01, the cloud server obtains the user's personal information and sends a control instruction to open the recycling port to the paper recycling device; the paper recycling device receives the control instruction and opens the recycling port;

[0048] S02, the user puts waste paper into the recycling port. The waste paper is weighed by the weighing unit. During the weighing process, the paper recycling device obtains the waste paper weight data and transmits the data to the cloud server; the weighed waste paper is shredded by the shredding unit, and after shredding, it enters the recycling bin and is pressed by the pressing unit;

[0049] S03, the induction unit senses the shredded paper volume in the recycling bin. When it reaches a preset value, the paper recycling device sends a message to the cloud server, and the cloud server sends a paper recycling message to the administrator after receiving the message.

[0050] In use, a human-machine interaction interface is provided on each paper recycling device, and a QR code is carried on the human-machine interaction interface. When a user uses the paper recycling device, they need to use a mobile phone or other terminal to scan the code. After scanning the code, a communication connection is established between the terminal and the cloud server. After scanning the code, the user needs to enter personal identity information. After entering the personal identity information, the cloud server sends a control instruction to the corresponding paper recycling device to control the paper recycling device to open the recycling port. The user feeds the waste paper into the paper recycling device along the recycling port. The waste paper is first transported by a conveyor belt to a weighing unit for weighing. After weighing, the weighing data is transmitted by the communication unit of the paper recycling device to the cloud server. The user can know the weight of the waste paper fed into the paper recycling device this time through the mobile terminal. The cloud server can give cash back or accumulate points according to the weight of the waste paper. After being weighed, the waste paper enters a shredding unit for shredding, and the shredded paper pieces enter a recycling bin and are pressed by a pressing unit. When the volume of the pressed waste paper in the recycling bin reaches the preset volume, the cloud server sends a recycling message to the administrator. The administrator opens the recycling bin of the paper recycling device by scanning the code and takes out the corresponding shredded paper. The cloud server stores the weight of the shredded paper taken out by the corresponding administrator this time. It can be seen that in the present invention, when the user inputs waste paper, it will be weighed. The cloud server will store the weight of the shredded paper input during each use of each paper recycling device, and then store the weight of the shredded paper taken out by the administrator each time. The user can monitor the paper weight on the mobile terminal.

[0051] A paper recycling device has a structure as Figure 4 shown, including a hollow housing 10, a human-machine interaction panel 11 located on the housing 10, and a recycling port 12 provided on the housing 10. The housing 10 is used to contact the ground and provide an installation space for internal components. The recycling port 12 is a through hole penetrating the housing 10. The internal structure of the paper recycling device is as Figure 5 shown, including a weighing unit 20, a shredding unit 30, a pressing unit 40, and a recycling bin 50 for storing shredded paper, which are fixed to the inner side surface of the housing 10.

[0052] The structure of the weighing unit 20 is as Figure 6 and Figure 7As shown in the figure, it includes a first motor 21, a conveyor belt 22, a weighing device 23, and a moisture detection device 24. The left and right sides of the conveyor belt 22 are respectively covered with rotating rollers. When the first motor 21 rotates, it drives the rotating roller on the left side to rotate through a rack or a zipper, thereby driving the conveyor belt 22 at the top to move from left to right. The rotating roller on the right side rotates passively, and the conveyor belt 22 at the bottom moves from right to left. The weighing device 23 is a rectangular electronic weighing plate located below the conveyor belt 22, and the moisture detection device is located on both sides of the conveyor belt 22. The user puts the paper into the recycling port 12. Then, the put paper is conveyed by the conveyor belt 22. When the paper completely enters the recycling port 12 and is on the conveyor belt 22, the first motor 21 stops working, and the weighing device 23 weighs the paper, and the moisture detection device 24 detects the moisture of the put paper. After weighing, the first motor 21 moves, and the paper is sent into the crushing unit through the conveyor belt 22. It should be noted that after receiving the instruction from the cloud server, the paper recycling device opens the recycling port 12 and controls the first motor 21 to rotate. When it detects that the paper has completely fallen onto the conveyor belt 22, it stops the rotation of the first motor 21 and starts weighing. The detection of the paper completely falling onto the conveyor belt 22 can be determined by image acquisition by the image acquisition unit or by setting sensors on the weighing unit.

[0053] The structure of the crushing unit 30 is similar to the prior art, such as Figure 6 and Figure 7 As shown in the figure, it mainly includes a second motor 31 and two mutually meshing blades 32 driven by the second motor 31. The output shaft of the second motor 31 is connected with a gear, and the same side of the blade 32 is connected with mutually meshing gears. The second motor 31 drives the blade 32 to rotate through the gears. The bottoms of the weighing unit 20 and the crushing unit 30 are fixedly connected through a mounting plate. The housing 10 is above the crushing unit 30. A rectangular connecting plate 33 is provided at the end of the weighing unit 20, and a discharge port 34 is provided below the blade 32 in the housing 10. After the paper is weighed by the weighing unit 20, it passes through the connecting plate 33 and enters the crushing unit 30 to be crushed by the blade 32. The crushed paper falls downward through the discharge port 34 into the recycling bin 50.

[0054] The internal layout diagram of the housing is as shown in Figure 8 As shown in the figure, the recycling bin 50 includes a horizontally arranged partition 51. The partition 51 and the bottom and side surfaces of the housing enclose a recycling bin 50 for recycling shredded paper. The recycling bin 50 is located below the weighing unit 20 and the crushing unit 30 and is a hollow cuboid structure.

[0055] The structure of the pressing unit 40 is as shown in Figure 9 As shown in the figure, it includes a hydraulic drive mechanism 41, a pressing die cylinder 42 vertically arranged and connected to the hydraulic drive mechanism 41, and a pushing cylinder 43 horizontally arranged and connected to the hydraulic drive mechanism 41. The structure of the hydraulic drive mechanism 41 is as shown in Figure 10As shown in the figure, it includes an electric motor hydraulic pump 411, a hydraulic oil tank 412, a hydraulic pipe 413, and a hydraulic valve 414. The electric motor hydraulic pump 411 is connected to the hydraulic oil tank 412 through the hydraulic pipe 413, and is respectively connected to the die pressing cylinder 42 and the pushing cylinder 43 through the hydraulic pipe 413 and the hydraulic valve 414. The hydraulic pump 411 transports the hydraulic oil in the hydraulic oil tank 412 to the die pressing cylinder 42 or the pushing cylinder 43 through the hydraulic pipe 413, and the die pressing cylinder 42 or the pushing cylinder 43 moves by changing the pressure of the hydraulic oil in the die pressing cylinder 42 or the pushing cylinder 43.

[0056] The structure of the die pressing cylinder 42 is as Figure 11 shown, including a die pressing cylinder body 421, a fixing plate 422 located at the top of the die pressing cylinder body 421 and fixedly connected to the housing 10, and a pressing plate 423 fixed to the bottom of the die pressing cylinder body 421. The die pressing cylinder 42 is located within a rectangular frame. The rectangular frame is used to wrap the die pressing cylinder 42 and separate the die pressing cylinder 42, the crushing unit 30, and the hydraulic oil tank 412. Vertical plates 424 are also provided on both sides of the rectangular frame. The outer side of the vertical plate 424 is fixed to the housing 10, and the inner side forms a pressing space for pressing shredded paper with the pressing plate 423. The shredded paper after crushing falls into the pressing space and is pressed by the pressing plate 423 to form a cuboid structure.

[0057] The structure of the pushing cylinder 43 is as Figure 12 shown, including a pushing cylinder body 431 and a pushing plate 432 located at one end of the pushing cylinder body 431. The structures and working principles of the pushing cylinder 43 and the die pressing cylinder 42 are roughly the same. Both use multi-stage cylinders, and hydraulic oil is transported in / retrieved by the hydraulic pipe 413 to change the pressure, thereby driving the pushing cylinder 43 or the die pressing cylinder 42 to extend or contract. The difference is that the die pressing cylinder 42 presses vertically. First, the shredded paper is vertically extruded. After the vertical extrusion is completed, the shredded paper is formed into a cuboid shape, and then the pushing cylinder 43 is controlled to perform horizontal extrusion, so that the cuboid-shaped shredded paper is located on one side of the recycling port. The control of the pushing cylinder 43 and the die pressing cylinder 42 is achieved by controlling the corresponding hydraulic valve and the electric motor hydraulic pump 411.

[0058] A sensor for detecting the volume of shredded paper (not shown in the attached drawings) is also provided on the partition 51 of the recycling box 50. When the shredded paper is full, the sensor sends a signal to the control unit, and the control unit sends the signal to the cloud server correspondingly, and the cloud server sends information about the recycled paper to the administrator.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
