Description

Technical Field

[0001] This utility model relates to the field of waste cardboard box processing technology, and more specifically, it relates to a recycling device for waste cardboard boxes. Background Technology

[0002] With the growing awareness of environmental protection and the urgent need for resource recycling, the development of efficient recycling technologies for waste cardboard boxes, as an important renewable resource, is crucial. Currently, various waste cardboard box recycling devices exist on the market, mainly using methods such as compaction and cutting to reduce the volume and break down waste cardboard boxes, facilitating subsequent resource recycling.

[0003] For example, Chinese patent CN222136040U discloses a recycling device for waste cardboard boxes. This device, through the cooperation of a fixed column, a processing box, and a cylinder, achieves the pressing and shaping of waste cardboard boxes, followed by crushing using a shredder, thus improving the recycling efficiency to some extent. However, such recycling devices still have many problems that urgently need to be solved. On the one hand, in the compaction stage, the cylinder compaction method used in the aforementioned patent has limited compaction speed due to its mechanical motion characteristics, making it difficult to meet the needs of large-scale, high-efficiency recycling. On the other hand, the entire recycling process, from placing the waste cardboard boxes into the processing box, pushing the pusher to send the flattened boxes into the feed inlet, controlling the opening and closing of the baffle to allow the boxes to enter the shredder, and removing the processed waste cardboard boxes, all rely on manual labor. This not only increases labor costs but also severely restricts the improvement of recycling efficiency, failing to meet the requirements of modern industrialized large-scale waste cardboard box recycling.

[0020] 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.

[0021] Please see Figure 1-2 As shown, an embodiment of the present invention provides a recycling device for waste paper boxes, including a recycling box 1 and a compaction box 2 located at the bottom of the recycling box 1. The recycling box 1 is formed with a first cavity 10 and a hopper 11 connected to the first cavity 10 is formed at the top. The first cavity 10 is provided with a first guiding mechanism, a cutting mechanism, a second guiding mechanism and a crushing mechanism arranged sequentially from top to bottom. The compaction box 2 is formed with a second cavity 20 and a discharge channel 21 is formed between the second cavity 20 and the bottom of the first cavity 10. The second cavity 20 is provided with a compaction mechanism for compacting shredded paper into blocks. The right end of the compaction box 2 is provided with a discharge port 22 and a door 23 is hinged to the discharge port 22.

[0022] In use, waste paper boxes are fed from hopper 11 into the first cavity 10 of recycling box 1. They are first guided by the first guiding mechanism to the cutting mechanism, which performs preliminary cutting and crushing of the paperboard. Then, the second guiding mechanism guides the preliminarily crushed paper to the crushing mechanism, which further crushes the paper. The crushed paper then enters the second cavity 20 of compaction box 2 through discharge channel 21. The second cavity 20 contains a compaction mechanism for compacting the paper into blocks.

[0023] The first guiding mechanism and the second guiding mechanism have the same structure. The first guiding mechanism or the second guiding mechanism includes two guide plates 3 arranged symmetrically on the left and right. The upper ends of the two guide plates 3 extend outward and upward in an inclined manner, and a funnel-shaped structure with a wider upper part and a narrower lower part is formed between the two guide plates 3. At least two crossbars 30 are provided on the opposite side of the two guide plates 3. The two crossbars 30 are arranged in parallel and their other ends are fixedly connected to the inner wall of the first cavity 10.

[0024] In use, the funnel-shaped structure formed by the two guide plates 3 of the first guide mechanism guides the waste paper downward to the cutting mechanism; similarly, the two guide plates 3 of the second guide mechanism guide the shredded paper to the crushing mechanism; the lateral stiffness of the first guide plate 3 or the second guide plate 3 is increased by setting a crossbar 30.

[0025] Among them, the guide plate 3 of the first guide mechanism and the second guide mechanism can be made of steel plate of appropriate thickness, and the crossbar 30 can be made of round steel. The crossbar 30 is fixedly connected to the guide plate 3 and the inner wall of the first cavity 10 by welding or other means.

[0026] The cutting mechanism includes two symmetrically and rotatably arranged conveyor rollers 4, and two symmetrically and rotatably arranged cutting rollers 40 below the two conveyor rollers 40. The outer surface of the cutting rollers 40 has a number of cutting rings 41 that are equidistantly and spaced apart.

[0027] In use, the two conveying rollers 4 rotate in opposite directions to transport the waste paper box to the two cutting rollers 40. The cutting rollers 40 rotate in opposite directions to cut the waste paper box, and the cut paper continues to move downward.

[0028] Specifically, the outer surface of the cutting roller 40 has several cutting rings 41 that are equidistant and spaced apart. Each piece of cardboard is cut into strips after passing through two cutting rollers 40, and then guided into the crushing mechanism in strip form by the second guiding mechanism.

[0029] The conveying roller 4 and the cutting roller 40 are configured using conventional techniques in the field. They are mounted on the side wall of the first cavity 10 via bearing seats, achieving a rotatable connection. The driving method of the conveying roller 4 and the cutting roller 40 is also a conventional design in the field. They are connected to an external motor or drive device, and the motor outputs power, which is transmitted to the conveying roller 4 and the cutting roller 40 through common transmission methods such as transmission belt, gear transmission or chain transmission, driving them to rotate at a predetermined speed and direction. In practical applications, a motor with appropriate power and a suitable transmission ratio can be selected according to the waste paper box processing requirements to ensure that the conveying roller 4 can stably convey waste paper boxes and the cutting roller 40 can efficiently complete the cutting operation.

[0030] The crushing mechanism includes two crushing rollers 5 symmetrically installed above the discharge channel 21, and scraper plates 50 are provided on the inner wall of the recycling box 1 on the opposite side of the two crushing rollers 5.

[0031] When in use, the crushing roller 5 and scraper 50 of the crushing mechanism work together to fully crush the cut paper shreds, achieving ideal processing results and making the shredded paper more suitable for subsequent recycling.

[0032] The crushing rollers are set up using conventional techniques in the field. During operation, the two crushing rollers rotate towards each other. Scraper plates 50 are provided on the inner wall of the recycling box 1 on the opposite sides of the two crushing rollers 5. The scraper plates 50 are fixed to the inner wall of the box using conventional installation methods in the field. Their positions are adapted to the crushing rollers 5 and are used to scrape off the shredded paper attached to the surface of the crushing rollers 5 in a timely manner, ensuring the continuous and efficient crushing operation.

[0033] The compaction mechanism includes a first power source 24 fixedly mounted on the left side of the compaction box 2. The output shaft of the first power source 24 extends through into the compaction box 2 and is connected to an extrusion block 25. A blocking block 26 that cooperates with the extrusion block 25 is also movably arranged inside the compaction box 2. A baffle 27 is provided on the top left side of the extrusion block 25. The baffle 27 is used to block the discharge channel 21 when the extrusion block 25 is extruding. A stand 6 is provided on the top of the compaction box 2, and a second power source 60 is fixedly mounted on the top of the stand 6. An opening 61 is opened on the top of the compaction box 2 at the corresponding position of the stand 6. The output shaft of the second power source 60 extends through the opening 61 into the compaction box 2 and is drivenly connected to the blocking block 26.

[0034] In use, initially, the extrusion block 25 blocks the inside of the door 23 of the compaction box 2. The first power source 24 drives the extrusion block 25 to move toward the blocking block 26 to perform the extrusion action. The extrusion block 25 and the blocking block 26 work together to compress the shredded paper into blocks. Then, the second power source 60 drives the blocking block 26 to exit the compaction box 2. At this time, the first power source 24 drives the compaction block to push the material block out from the discharge port 22, so that the material block can be stored and transported later.

[0035] When the extrusion block 25 is pressing, the baffle 27 blocks the discharge channel 21, which ensures that the material is confined to a specific area for extrusion and prevents the material from flowing out of the discharge channel 21 during the extrusion process, thus ensuring the extrusion effect and the accuracy of material processing. When the extrusion block 25 is reset, the raw material can fall into the second cavity 20 according to the design path under the obstruction of the box body, preventing the material from flowing randomly during the extrusion process and avoiding the material from affecting the operation of other components.

[0036] The first power source 24 and the second power source 60 can be hydraulic motors or electric push rods, etc. The appropriate power source can be selected according to actual needs to ensure that sufficient power can be provided to compact the shredded paper into blocks.

[0037] The recycling bin 1 and the compaction bin 2 can be made of metal to ensure the strength and durability of the device. The opening size of the hopper 11 can be designed according to actual needs to facilitate the disposal of waste paper boxes. During actual use, the device can be maintained and serviced regularly, the operation of each component can be checked, and residual paper scraps inside the device can be cleaned in a timely manner to ensure the normal operation of the device.

[0038] The first and second guiding mechanisms can also be implemented in the following ways:

[0039] See the attached instruction manual. Figure 2 In the second embodiment of the first or second guiding mechanism, two slide rods 7 are provided on the opposite sides of the two guide plates 3, and the slide rods 7 are slidably connected to the recycling bin 1; a threaded sleeve 70 is formed between the two slide rods 7 on the guide plate 3, and a screw 71 that cooperates with the threaded sleeve 70 is rotatably provided between the two guide plates 3. An adjustment knob 72 is formed on the outer end of the screw 71; by rotating the adjustment knob 72, the screw 71 is driven to rotate, and the threaded connection between the screw 71 and the threaded sleeve 70, as well as the sliding guidance effect between the slide rods 7 and the bin, is used to adjust the distance between the two guide plates 3.

[0040] In practical applications, when processing waste paper boxes of different sizes, operators can rotate the adjustment knob 72 to make the screw 71 rotate and advance or retract within the threaded sleeve 70. Since the slide bar 7 is slidably connected to the recycling bin 1, it can limit the movement direction of the guide plate 3, ensuring that the guide plate 3 moves smoothly only in the horizontal direction, avoiding unnecessary shaking caused by the rotation of the screw 71. When processing larger waste paper boxes, the distance between the two guide plates 3 can be increased to facilitate the smooth passage of the waste paper boxes. When processing smaller waste paper boxes or shredded paper, the distance between the guide plates 3 can be reduced to enhance the guiding and gathering effect on the materials. This allows the recycling device to flexibly adapt to the processing needs of waste paper boxes of different sizes, significantly improving the versatility and practicality of the device.

[0041] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
