Description

Technical Field

[0001] This application relates to the technical field of waste cardboard recycling, and in particular to a waste cardboard crushing and recycling device. Background Art

[0002] At present, with the increasing awareness of environmental protection, the recycling of waste paper resources has received more and more attention. As a recyclable green papermaking raw material, waste paper fibers play an important role in the papermaking industry due to their simpler pulping process, water conservation and energy saving, less resource consumption and pollutant emissions.

[0003] Existing waste cardboard recycling devices generally include main components such as crushers, recycling bins, and water inlets. In the actual operation process, first, the waste cardboard is put into the crusher, and the cardboard is crushed into shredded paper by the operation of the crusher. This step aims to reduce the volume of the cardboard for subsequent processing. Then, the shredded paper after crushing is conveyed into the recycling bin, and then water is injected into the recycling bin from the water inlet. At this time, the mixer starts to work, and its stirring rod rotates at a high speed driven by the motor to stir the shredded paper and water in the bin. The purpose is to make the shredded paper and water fully mixed, wet the shredded paper and gradually transform it into a pulp state. After the stirring is completed, the uniformly mixed pulp is poured out of the recycling bin for further processing.

[0004] However, there are still some defects in the existing technology in actual application. For example, the stirring rod of the mixer is prone to winding pulp fibers during the stirring process. Due to the continuous high-speed rotation of the stirring rod, once the pulp fibers adhere, it is very difficult to fall off by itself during the stirring process. As the stirring continues, more and more winding pulp fibers will accumulate. If not cleaned in time, it will increase the operating resistance of the stirring rod, resulting in an increase in the motor load and energy consumption. Therefore, it is necessary to manually stop the machine for cleaning regularly, which not only consumes a lot of time and manpower, but also affects the overall processing efficiency.

Detailed implementation mode

[0025] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, but should not be construed as a limitation of the present application.

[0026] The waste cardboard crushing and recycling device according to the embodiment of the present application will be described below with reference to the drawings.

[0027] As Figures 1 - 5 shown, the waste cardboard crushing and recycling device according to the embodiment of the present application may include a support platform 10, a recycling bin 20, a crusher 30, a stirring assembly 40 and a driving assembly 50.

[0028] Among them, the recycling bin 20 is arranged on the support platform 10, and a discharge pipe 21 with a valve is arranged at the bottom of the recycling bin 20. This design facilitates discharging the made pulp from the recycling bin 20 by opening the valve after stirring, so as to facilitate subsequent processing. The crusher 30 is arranged on the recycling bin 20, and the discharge port of the crusher 30 is communicated with the recycling bin 20.

[0029] The stirring assembly 40 is rotatably arranged in the recycling bin 20. The stirring assembly 40 may include a cylinder body 41, a plurality of stirring mechanisms 42, multiple groups of cleaning mechanisms 43 and a power source 44. Among them, the cylinder body 41 is vertically and rotatably arranged in the middle of the inner cavity of the recycling bin 20, and the bottom end of the cylinder body 41 penetrates through the bottom wall of the recycling bin 20.

[0030] Furthermore, a plurality of grooves 401 distributed in a circumferential array are formed on the cylinder body 41, and an installation channel 402 is formed at one end of the cylinder body 41 close to the groove 401. The installation channel 402 is communicated with the groove 401.

[0031] A plurality of stirring mechanisms 42 are arranged in a circumferential array and rotatably arranged on the cylinder body 41. For example, the plurality of stirring mechanisms 42 can be 3, 4, 5, 6 stirring mechanisms 42, etc. The specific number used can be selected according to the actual situation (such as 4 stirring mechanisms 42), which is not limited herein. A plurality of cleaning mechanisms 43 are respectively arranged on the cylinder body 41, and the plurality of cleaning mechanisms 43 are respectively distributed in one-to-one correspondence with the plurality of stirring mechanisms 42. Among them, the cleaning mechanism 43 is used to clean the pulp fibers wound around the stirring mechanism 42.

[0032] The power source 44 is rotatably arranged in the cylinder body 41, and the power source 44 is respectively connected to the plurality of stirring mechanisms 42. Among them, the power source 44 is used to drive the plurality of stirring mechanisms 42 to perform synchronous flipping. The driving assembly 50 is arranged on the support platform 10, and the driving assembly 50 is connected to the cylinder body 41. Among them, the driving assembly 50 is used to drive the cylinder body 41 to rotate.

[0033] It can be understood that when it is necessary to crush and recycle waste cartons, the relevant staff can convey the waste cartons to the crusher 3 for crushing. The crushed cartons enter the cylinder body 41, and then the staff inject water into the cylinder body 41 through the discharge pipe 21 and make the water level submerge the stirring mechanism 42.

[0034] At this time, control the driving assembly 50 to drive the cylinder body 41 to drive the stirring mechanism 42 and the power source 44 to rotate, and stir the paper scraps and water in the recycling box 20 through the plurality of circumferentially rotating stirring mechanisms 42.

[0035] During this process, the power source 44 can also be controlled to drive the plurality of stirring mechanisms 42 to perform radial (the direction of the center line of the cylinder body 41) reciprocating swing to expand the stirring range and enhance the stirring effect.

[0036] When it is necessary to clean the pulp fibers wound around the stirring mechanism 42, the power source 44 can be controlled to drive the plurality of stirring mechanisms 42 to respectively flip into the corresponding grooves 401, and the cleaning mechanism 43 is used to scrape off the pulp fibers wound around the stirring mechanism 42. Furthermore, it can effectively remove the wound pulp fibers attached to the stirring rod, avoid the accumulation of wound pulp fibers increasing the stirring resistance, reduce the motor load and energy consumption, and there is no need for manual shutdown cleaning throughout the process, effectively improving the waste paper recycling and processing efficiency.

[0037] For the sake of clearly illustrating the previous embodiment, in an embodiment of the present application, as Figure 3 and Figure 4 shown, the stirring mechanism 42 can include a worm gear 421 and a stirring rod 422. Among them, the worm gear 421 is rotatably arranged in the installation channel 402. One end of the stirring rod 422 is fixedly connected to the worm gear 421, and the other end of the stirring rod 422 extends out of the installation channel 402. Among them, the stirring rod 422 is in a triangular prism shape.

[0038] It is understandable that the special shape of the triangular prism-shaped stirring rod 422 can disperse materials better, improve the stirring efficiency, and promote the uniform mixing of paper scraps and water compared with the ordinary cylindrical stirring rod. At the same time, when the triangular prism-shaped stirring rod 422 passes between the two elastic scraping plates 431, the pulp fibers attached to the triangular prism-shaped stirring rod 422 can be effectively removed. That is, the two elastic scraping plates 431 scrape the pulp fibers wound around the stirring rod 422 along the two surfaces of the triangular prism-shaped stirring rod 422.

[0039] Furthermore, in an embodiment of the present application, as Figure 4 shown, the power source 44 may include a worm 441 and a first driving mechanism 442. Among them, the worm 441 is rotatably arranged in the cylinder body 41, and the worm 441 meshes with the worm gear 421.

[0040] The first driving mechanism 442 is arranged at the bottom end of the cylinder body 41, and the output end of the first driving mechanism 442 is connected to the worm 441. It should be noted that the first driving mechanism 442 described in this embodiment may be a bidirectional stepping motor, that is, the output shaft of the stepping motor can realize forward and reverse rotation switching.

[0041] After the first driving mechanism 442 is started, its output end drives the worm 441 to rotate. The rotation of the worm 441 drives the worm gear 421 to rotate through the meshing action, and then drives the stirring rod 422 to swing back and forth to expand the stirring range and improve the stirring effect.

[0042] Furthermore, in an embodiment of the present application, as Figure 5 shown, each set of cleaning mechanisms 43 may include two cleaning mechanisms 43 symmetrically arranged in the groove 401, and the opposite faces of the two cleaning mechanisms 43 are in contact. Each cleaning mechanism 43 may include an elastic scraping plate 431 and a rubber sleeve 432. Among them, the elastic scraping plate 431 is obliquely and fixedly arranged on the inner side wall of the groove 401. That is, the height of the relative ends of the two elastic scraping plates 431 is lower than the height of the other ends. The rubber sleeve 432 is integrally formed and sleeved on the elastic scraping plate 431, and the length of the stirring rod 422 does not exceed the length of the elastic scraping plate 431. It is understandable that through the cooperation of the elastic scraping plate 431 and the rubber sleeve 432, the pulp fibers on the stirring rod 422 can be effectively cleaned. The elastic scraping plate 431 provides a scraping force, and the rubber sleeve 432 can not only enhance the scraping effect but also protect the surface of the stirring rod 422 from damage, ensuring that the stirring rod 422 always maintains good stirring performance during long-term operation and avoiding the influence of pulp fiber accumulation on the stirring efficiency.

[0043] In the embodiment of the present application, in order to prevent liquid from entering the cylinder body 41 through the installation channel 402 and affecting the rotation of the worm 441 driving the worm wheel 421, an elastically deformable sealing rubber ring (not shown in the figure) can also be sleeved at the connection between the stirring rod 422 and the worm wheel 421, and the sealing rubber ring is hermetically connected to the inner wall of the installation channel 402 for sealing the installation channel 402.

[0044] Specifically, when the stirring rod 422 rotates close to the two symmetrically distributed elastic scraping plates 431 arranged in the corresponding groove 401, the elastic scraping plates 431 and the rubber sleeve 432 utilize their own elastic deformation to closely fit the surface (both sides) of the stirring rod 422, scraping off the pulp fibers attached to the stirring rod 422 to prevent the pulp fibers from accumulating.

[0045] Further, in an embodiment of the present application, as Figure 3 shown, the driving assembly 50 may include a second driving mechanism 51 and a belt transmission mechanism 52. Among them, the second driving mechanism 51 is arranged on the support table 10, and the output end of the second driving mechanism 51 is connected to the cylinder body 41 through the belt transmission mechanism 52. It should be noted that the second driving mechanism 51 described in this embodiment may be a servo motor.

[0046] It should be noted that the belt transmission mechanism 52 described in this embodiment may include two belt pulleys and a belt. One of the belt pulleys is connected to the output end of the second driving mechanism 51, and the other belt pulley is sleeved and fixed on the cylinder body 41, and the belt is sleeved on the two belt pulleys. The staff can drive the belt transmission mechanism 52 to drive the cylinder body 41 to rotate by starting the second driving mechanism 51.

[0047] Further, in an embodiment of the present application, as Figure 1 shown, the crusher 30 may include a crushing box 31, two crushing mechanisms 32, two gears 33 and a third driving mechanism 34. Among them, the crushing box 31 is arranged on the recycling box 20, and the crushing box 31 is communicated with the recycling box 20.

[0048] The two crushing mechanisms 32 are arranged side by side and rotatably in the crushing box 31. Each crushing mechanism 32 may include a support shaft 321 and a plurality of crushing knives 322. Among them, the support shaft 321 is rotatably arranged in the crushing box 31, and the plurality of crushing knives 322 are equidistantly arranged side by side and sleeved and fixed on the support shaft 321. For example, the plurality of crushing knives 322 may be 8, 9, 10, 11, 12 crushing knives 322, etc. The specific number used can be selected according to the actual situation and is not limited herein, and the crushing knives 322 in the two crushing mechanisms 32 are arranged in a staggered manner.

[0049] Two gears 33 are respectively connected to one end of the corresponding support shaft 321, and the two gears 33 are meshed with each other. The third driving mechanism 34 is arranged on the crushing box 31, and the output end of the third driving mechanism 34 is connected to the other end of one of the support shafts 321. It should be noted that the third driving mechanism 34 described in this embodiment can be a driving motor.

[0050] It can be understood that the waste cardboard box is put into the crushing box 31 of the crusher 30, and the third driving mechanism 34 is started. The output end of the third driving mechanism 34 drives one of the support shafts 321 to rotate. Since the gears 33 at one end of the two support shafts 321 are meshed with each other, the other support shaft 321 will also rotate accordingly. The rotation of the support shaft 321 drives the plurality of crushing knives 322 to rotate, and the staggered crushing knives 322 cut and crush the waste cardboard box, turning it into shredded paper. The shredded paper after crushing falls into the lower recycling box 20 through the discharge port of the crusher 30.

[0051] Specifically, in the actual implementation process, when waste cardboard boxes need to be crushed and recycled, the staff first put the waste cardboard boxes into the crusher 30 for cutting and crushing, turning them into shredded paper. The shredded paper after crushing falls into the lower recycling box 20 through the discharge port of the crusher 30.

[0052] Then, an appropriate amount of water is injected into the recycling box 20, and the first driving mechanism 442 and the second driving mechanism 51 are started. The first driving mechanism 442 drives the worm 441 to rotate forward and backward in a switching manner. The worm 441 is meshed with the worm wheel 421, so that the worm wheel 421 drives the stirring rod 422 to flip back and forth. At the same time, the second driving mechanism 51 drives the cylinder body 41 to rotate through the belt transmission mechanism 52, so that the whole stirring assembly 40 rotates, stirring the shredded paper and water in the recycling box 20, promoting the full mixing of the shredded paper and water, and accelerating the process of converting the shredded paper into pulp.

[0053] When it is necessary to clean the pulp fibers wound on the stirring rod 422, the staff can control the first driving mechanism 442 to drive the worm 441 to drive the worm wheel 421 to rotate in a single reverse direction towards the corresponding groove 401, and make the stirring rod 422 rotate into the groove 401. Since the length of the stirring rod 422 does not exceed the length of the elastic scraping plate 431, when the stirring rod 422 passes through the cleaning mechanism 43, the elastic scraping plate 431 and the rubber sleeve 432 can timely scrape off the pulp fibers attached to the stirring rod 422, preventing the accumulation of pulp fibers. These scraped pulp fibers fall back into the recycling box 20 to continue participating in the stirring. The whole process does not require manual shutdown for cleaning, ensuring the continuous and efficient progress of the stirring work.

[0054] When the stirring is completed and the shredded paper in the recycling box 20 is fully converted into pulp, the valve on the discharge pipe 21 at the bottom of the recycling box 20 is opened, and the pulp is discharged through the discharge pipe 21 for subsequent processing.

[0055] In summary, the waste carton crushing and recycling device according to the embodiments of the present application can effectively remove the pulp fibers attached to the stirring rod, avoid the accumulation of pulp fibers to increase the stirring resistance, reduce the motor load and energy consumption, and does not require manual shutdown and cleaning throughout the process, effectively improving the efficiency of waste paper recycling and processing.
