Description

Technical Field

[0001] This utility model relates to the field of renewable resource recycling technology, specifically a crushing device for renewable resource recycling. Background Technology

[0002] Paper is a common material with high recycling value. Its recycling process includes multiple steps such as sorting, crushing, and pulping. Crushing is a key preliminary step in paper recycling.

[0003] Currently, most paper shredding devices on the market adopt a general-purpose shredding structure, which randomly shreds paper using rotating blades or rollers. However, existing shredding devices can only shred paper once. When secondary shredding is required, workers need to remove the paper and put it back into the shredding device, which is not only inefficient and increases labor, but also cannot compress the shredded paper.

[0004] According to the description in the patent announcement (authorization announcement number: CN221453806U) of a crushing device for recycling renewable resources, the crushing device includes a "crushing chamber and a discharge chamber" to achieve the crushing work.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This recycling crushing device utilizes a crushing chamber and a discharge chamber to perform crushing operations. However, the crushing chamber only allows for one-time crushing, which cannot guarantee complete crushing and affects the quality. When secondary crushing is required, workers must remove the initially crushed material and re-input it, impacting crushing efficiency. Therefore, improvements to this device are necessary.

[0018] Compared with the prior art, the present invention provides a crushing device for recycling renewable resources, which has the following beneficial effects:

[0019] 1. This recycling crushing device, through its crushing mechanism, allows for the initial crushing of paper during the recycling process. A fixed amount of paper is first fed into the crusher body, where it is crushed. The baffle is positioned away from the guide plate, guiding the initially crushed material through the guide plate to the conveying pipe. The guide plate, with its concave top located at the bottom of the crusher body, effectively collects material and prevents spillage. Inside the conveying pipe, an auger, driven by a servo motor, further conveys the initially crushed paper through a connecting pipe back into the crusher body for secondary crushing. When the paper is fully crushed... When the material returns to the crusher body, the first hydraulic cylinder moves the baffle inside the guide plate to seal it. At the same time, the third hydraulic cylinder moves the conveying pipe, causing the connecting arm to slide inside the load-bearing frame. This moves the top left end of the conveying pipe away from the bottom of the guide plate. Once away, the first hydraulic cylinder moves the baffle away from the inside of the guide plate. After the crusher body performs secondary crushing on the paper, the crushed paper enters the bottom of the recycling bin. The second hydraulic cylinder pushes the extrusion plate to slide inside the recycling bin, which compresses the crushed material, further reducing its volume and improving the utilization rate of the recycling bin.

[0020] 2. This recycling crushing device, through its limiting mechanism, ensures that when the recycling bin is collecting crushed paper and the sealing door is sealed, the rectangular frame, adjusting shaft, knob, first limiting frame, and second limiting frame work together. By rotating the knob, the position of the first limiting frame within the rectangular frame is adjusted, thereby driving the second limiting frame to limit and fix the sealing door, ensuring that the sealing door is stable and reliable after closing, preventing accidental opening, and further improving the safety and convenience of the device.

[0040] Example 2

[0041] Please see Figure 1-7 Furthermore, based on Embodiment 1, the limiting mechanism 3 further includes a rectangular frame 31, which is fixedly connected to the right side of the recycling bin 21. An adjusting shaft 32 is rotatably connected inside the rectangular frame 31. A knob 33 is fixedly connected to the right side of the adjusting shaft 32.

A connecting frame 35 is fixedly connected to the bottom of the first limiting frame 34. A second limiting frame 36 is fixedly connected to the bottom of the connecting frame 35. The second limiting frame 36 is located in front of the sealing door 22.

[0042] The inner sides of the first limiting frame 34 and the second limiting frame 36 are in contact with the front side of the sealing door 22, and the first limiting frame 34 is slidably connected within the rectangular frame 31, so as to ensure the stability of the sealing door 22 through the first limiting frame 34 and the second limiting frame 36.

[0043] In actual operation, when this device is used, and paper needs to be recycled and crushed during the recycling process, a fixed amount of paper is first put into the crusher body 23 to avoid putting too much paper in at once and affecting the crushing effect. The crusher body 23 is powered by an external power supply to make it work. The crusher body 23 crushes the paper, and the baffle 292 is away from the inside of the guide plate 25, so that the material after the initial crushing is guided to the conveying pipe 293 through the guide plate 25. The top of the guide plate 25 is concave and located at the bottom of the crusher body 23, which can effectively collect the material and prevent spillage. The auger 298 in the conveying pipe 293, driven by the servo motor 295, can further convey a fixed amount of paper that has been crushed in the initial crushing to the crusher body 23 through the connecting pipe 299 for secondary crushing.

[0044] When all the paper returns to the shredder body 23, the first hydraulic cylinder 26 drives the baffle 292 to move into the guide plate 25. When the baffle 292 moves, it will drive the slide rod 291 to slide inside the recycling box 21, sealing the guide plate 25. At the same time, the third hydraulic cylinder 296 drives the conveying pipe 293 to move, so that the conveying pipe 293 drives the connecting arm 294 to slide inside the load-bearing frame 24. This will make the top left end of the conveying pipe 293 move away from the bottom of the guide plate 25. After it moves away, the baffle 292 will move away from the inside of the guide plate 25 again under the action of the first hydraulic cylinder 26. At this time, the shredder body 23 can perform secondary shredding on the paper. The shredded paper will enter the bottom of the recycling box 21 through the guide plate 25.

[0045] The second hydraulic cylinder 27 pushes the extrusion plate 28 to slide inside the recycling box 21, which can extrude the crushed material, further reduce the material volume, and improve the utilization rate of the recycling box 21. The structural design of the guide rod 29 inside the extrusion plate 28, the sliding rod 291 on the left side of the baffle 292, and the connecting arms 294 on the front and rear sides of the conveying pipe 293 ensures the stability and accuracy of each component during the movement. The bottom of the extrusion plate 28 contacts the bottom of the recycling box 21, and the front and rear sides contact the rear side of the sealing door 22 and the rear side of the recycling box 21, respectively. When extruding the material, it can form a closed space to prevent material leakage.

[0046] When the recycling bin 21 is collecting the shredded paper and the sealing door 22 is sealed, the position of the first limiting frame 34 within the rectangular frame 31 is adjusted by rotating the knob 33, thereby driving the second limiting frame 36 to limit and fix the sealing door 22, ensuring that the sealing door 22 is stable and reliable after closing, preventing accidental opening, and further improving the safety and convenience of the device. When it is necessary to centrally process the crushed paper, simply rotate the knob 33 to move the first limiting frame 34 and the second limiting frame 36 away from the front of the sealing door 22 to open the sealing door 22 and take out the paper for processing.

[0047] The crusher body 23 in this case is prior art. During use, the dust from the crushing can be adsorbed by an external dust adsorption device on the top of the crusher. The dust adsorption device is prior art, and those skilled in the art can select it according to requirements. This is common knowledge for those skilled in the art. Furthermore, the first hydraulic cylinder 26, the second hydraulic cylinder 27, the third hydraulic cylinder 296, the servo motor 295, and the crusher body 23 can be connected to the same PLC control system to ensure coordinated operation between the devices. PLC control is prior art, and those skilled in the art are well aware of the specific operating steps and methods of this system.
