Description

Technical Field

[0001] This utility model relates to the field of paper recycling technology, specifically a paper recycling compression system. Background Technology

[0002] A paper recycling compression system is a device used to compress waste paper into blocks for easier transportation and subsequent processing. This system plays a crucial role in the paper recycling process, significantly reducing waste paper volume, improving transportation efficiency, lowering transportation costs, and facilitating subsequent recycled paper production. The existing technology is authorized by publication number CN 108080395. Patent A discloses a cardboard box processing device, including a cardboard box compression device, a primary crushing device, a secondary crushing device, a storage bin shell, an inner box, a handle, and a support frame. The cardboard box compression device is fixedly installed at the top of the support frame, and the primary crushing device is located below the cardboard box compression device and is fixedly installed on the support frame. During the compression process, although the device can drive the lead screw to rotate through two sets of motors, and then the lead screw drives the sliding push plate to move through the threaded connection, the rotation amplitude of the two sets of lead screws is difficult to be completely uniform. The uneven rotation amplitude of the lead screws will cause uneven force on the sliding push plate. This uneven force may cause deformation or damage to the sliding push plate. Therefore, we propose a compression system for paper recycling. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a paper recycling compression system. By cooperating with the connecting seat and the bidirectional screw, the position of the pressure plate can be adjusted to compress the paper.

The pressure plate is driven by the drive assembly. Through the cooperation of the connecting seat and the bidirectional screw, the position of the pressure plate can be adjusted, thereby compressing the paper. The whole process can be completed by only one servo motor, which reduces the number of servo motors required and solves the problem of damage caused by uneven pressure on the pressure plate. The structure is simple and the service life of the pressure plate is improved.

[0008] Furthermore, the drive assembly includes a mounting base, a crossbar, an adjusting seat, a connecting seat, and a drive plate. The mounting base is located in the middle of the upper end of the mounting plate. A crossbar is slidably connected to a groove in the middle of the upper end of the mounting base.

[0010] Furthermore, a servo motor is provided on the upper right side of the housing. The left end of the servo motor output shaft is fixedly connected to the right end of the bidirectional screw.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a paper recycling compression system, including a box 1, a box door 3 hinged to the lower side of the front end of the box 1, a feed inlet 7 provided on the upper side of the front end of the box 1, and a compression mechanism 4.

[0021] Compression mechanism 4: It includes a mounting plate 43, fixing rods 44, a pressure plate 45, and a drive assembly 46. The pressure plate 45 is slidably connected to the inner wall of the housing 1. Fixing rods 44 are respectively provided on the left and right sides of the upper end of the pressure plate 45. The upper ends of the two fixing rods 44 are fixedly connected to the lower end of the mounting plate 43. The drive assembly 46 is located inside the housing 1, and the pressure plate 45 is driven by the drive assembly 46. The compression mechanism 4 also includes a fixing plate 41 and guide slides 42. The fixing plate 41 is respectively provided on the upper side of the left and right walls of the housing 1. Guide slides 42 are respectively provided between the upper end of the fixing plate 41 and the top wall of the housing 1. The four guide slides 42 are slidably connected to the corresponding sliding holes provided on the lower end of the mounting plate 43. The two fixing plates 41 are located on the upper side of the pressure plate 45. The drive assembly 46 is located inside the housing 1. Component 46 includes a mounting base 461, a crossbar 462, an adjusting seat 463, a connecting seat 464, and a drive plate 465. The mounting base 461 is located in the middle of the upper end of the mounting plate 43. The crossbar 462 is slidably connected to a groove in the middle of the upper end of the mounting base 461. The adjusting seats 463 are slidably connected to the left and right sides of the outer arc surface of the crossbar 462, respectively. Both adjusting seats 463 are slidably connected to the inner wall of the groove. The connecting seats 464 are slidably connected to the top wall of the housing 1. The lower ends of both connecting seats 464 are rotatably connected to the drive plate 465. The middle of the two drive plates 465 is rotatably connected by a pin. The lower end of the left drive plate 465 is rotatably connected to the right adjusting seat 463, and the lower end of the right drive plate 465 is rotatably connected to the left adjusting seat 463. The drive assembly 46 also includes a bidirectional screw 466, a first bellows 467, and a second bellows 468. The bidirectional screw 466 is rotatably connected to the upper side inside the housing 1. Connecting seats 464 are threaded to the left and right sides of the outer arc surface of the bidirectional screw 466 through threaded holes on their upper right ends. A first bellows 467 is positioned between the opposing inner surfaces of the two connecting seats 464. A second bellows 468 is positioned between the end of the connecting seat 464 furthest from the center of the housing 1 and the inner wall of the housing 1. Both the first bellows 467 and the second bellows 468 are sleeved on the outside of the bidirectional screw 466. During rotation, the bidirectional screw 466 drives the connecting seats 464 to move through the threaded connection. At this time, the first bellows 467 contracts, and the second bellows 468 contracts. The extension 68, with bellows 467 and 468 preventing direct contact between the bidirectional screw 466 and the external environment, and the gradually decreasing distance between the two connecting seats 464, thus reducing the distance between the two drive plates 465, causes the drive plates 465 to exert a downward thrust on the mounting seat 461 via the adjusting seat 463. The mounting seat 461 then moves the mounting plate 43 downward along the guide slide post 42, and the mounting plate 43, via the fixing rod 44, drives the pressure plate 45 downward, causing the lower end of the pressure plate 45 to contact the upper end of the paper, thereby compressing the paper. The entire process can be completed with only one drive device, reducing the number of drive devices required and solving the problem of damage caused by uneven force on the pressure plate 45.The simple structure also extends the service life of the pressure plate 45.

[0022] Among them, a microcontroller 2 is installed on the right end of the housing 1. The input terminal of the microcontroller 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0023] The upper right side of the housing 1 is equipped with a servo motor 5. The left end of the output shaft of the servo motor 5 is fixedly connected to the right end of the bidirectional screw 466. The input end of the servo motor 5 is electrically connected to the output end of the microcontroller 2. The servo motor 5 starts to run through the control of the microcontroller 2. The output shaft of the servo motor 5 drives the bidirectional screw 466 to rotate. During the rotation, the bidirectional screw 466 will drive the connecting seat 464 to move through the threaded connection.

[0024] Specifically: A laser rangefinder 6 is installed on the front side of the top wall of the housing 1. The laser rangefinder 6 is positioned vertically relative to the pressure plate 45. The laser rangefinder 6 is bidirectionally electrically connected to the microcontroller 2. During the operation of the laser rangefinder 6, the built-in light source of the laser rangefinder 6 emits a laser beam to the upper end of the pressure plate 45. After the laser beam comes into contact with the upper end of the pressure plate 45, it is reflected. Then the laser rangefinder 6 receives the reflected light. The laser rangefinder 6 calculates the distance between the lower end of the laser rangefinder 6 and the upper end of the pressure plate 45 by measuring the round-trip time (TOF) or phase difference of the laser beam.

[0025] The working principle of the paper recycling compression system provided by this utility model is as follows: Before use, the user first puts the paper to be compressed into the box 1 through the gap between the lower end of the pressure plate 45 and the feed port 7. Then, the operator measures the height inside the box 1, the thickness of the pressure plate 45, and the height of the laser rangefinder 6 (e.g., a, b, and c). Then, the height of the compressed paper block is set as d. Subsequently, the distance between the lower end of the laser rangefinder 6 and the upper end of the pressure plate 45 is measured. During the operation of the laser rangefinder 6, the built-in light source of the laser rangefinder 6 emits a laser beam to the upper end of the pressure plate 45. After the laser beam comes into contact with the upper end of the pressure plate 45, it is reflected. Then, the laser rangefinder 6 receives the reflected light. The laser rangefinder 6 measures the distance from the laser beam to the upper end of the pressure plate 45. The time of return (TOF) or phase difference is used to calculate the distance between the lower end of the laser rangefinder 6 and the upper end of the pressure plate 45 (e.g., let's call it e). Subsequently, the laser rangefinder 6 transmits the detected information to the microcontroller 2 via its built-in data transmission module. The microcontroller 2 receives the detected data through its built-in serial communication port. Subtracting the thickness of the pressure plate 45, the height of the laser rangefinder 6, the height of the paper block, and the distance between the lower end of the laser rangefinder 6 and the upper end of the pressure plate 45 from the height inside the housing 1 gives the distance between the lower end of the pressure plate 45 and the paper block (e.g., let's call it f, where f = abcde). Then, adding the distance between the lower end of the laser rangefinder 6 and the upper end of the pressure plate 45 to the distance between the lower end of the pressure plate 45 and the paper block gives the distance between the lower end of the pressure plate 45 and the paper block. After the paper is compressed, the distance between the lower end of the laser rangefinder 6 and the upper end of the pressure plate 45 (e.g., g, where g = e + f) is controlled by the microcontroller 2. Then, the servo motor 5 starts running, and the output shaft of the servo motor 5 drives the bidirectional screw 466 to rotate. During rotation, the bidirectional screw 466 moves the connecting seat 464 via a threaded connection. At this time, the first bellows 467 contracts, and the second bellows 468 extends. The first bellows 467 and the second bellows 468 prevent the bidirectional screw 466 from directly contacting the external environment. The distance between the two connecting seats 464 gradually decreases, thereby reducing the distance between the two drive plates 465. Because the distance is reduced, the drive plate 465 adjusts the mounting seat 461 via the adjusting seat 463. The downward thrust causes the mounting base 461 to move the mounting plate 43 downwards along the guide slide post 42. The mounting plate 43 then moves the pressure plate 45 downwards via the fixing rod 44, causing the lower end of the pressure plate 45 to contact the upper end of the paper, thereby compressing the paper. When the distance between the lower end of the laser rangefinder 6 and the upper end of the pressure plate 45 equals g, it indicates that the pressure plate 45 has compressed the paper into a block. Then, under the control of the microcontroller 2, the servo motor 5 reverses, and the output shaft of the servo motor 5 drives the bidirectional screw 466 to rotate. During the rotation, the bidirectional screw 466 moves the connecting seat 464 through the threaded connection. At this time, the distance between the two connecting seats 464 gradually increases, thereby increasing the distance between the two drive plates 465.The increased spacing of the drive plate 465, through the adjusting seat 463, provides an upward pull to the mounting seat 461. The mounting seat 461, carrying the mounting plate 43, moves upward along the guide slide post 42. The mounting plate 43, through the fixing rod 44, drives the pressure plate 45 upward, thus separating the lower end of the pressure plate 45 from the upper end of the paper block. When the distance between the lower end of the laser rangefinder 6 and the upper end of the pressure plate 45 equals e again, the servo motor 5 stops running under the control of the microcontroller 2. Then, the box door 3 is opened, and the operator can remove the compressed paper block.

[0026] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an ATmega328P, the servo motor 5 can be an ECMA-C20604RS, and the laser rangefinder 6 can be an HMLDM-UD100A. The microcontroller 2 controls the operation of the servo motor 5 and the laser rangefinder 6 using methods commonly used in the prior art.
