Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box processing, and more specifically, to a device for recycling waste materials from corrugated cardboard box cutting. Background Technology

[0002] Corrugated cardboard boxes are a type of packaging product. Corrugated cardboard is die-cut, creasing, and stapling or gluing to make corrugated cardboard boxes. Corrugated cardboard boxes are the most widely used packaging product, and their usage has always been the highest among all packaging products, including calcium-plastic corrugated cardboard boxes. In addition to protecting goods, facilitating warehousing and transportation, they also beautify and promote goods. Corrugated cardboard boxes are green and environmentally friendly products, which are beneficial to the environment and easy to load and unload. Cutting is required during the processing of corrugated cardboard boxes.

[0003] In the production and processing of corrugated cardboard boxes, the cutting process is an essential step. However, this process generates a large amount of waste. The large amount of corrugated cardboard box waste occupies valuable space and increases storage costs. On the other hand, if this waste is not recycled, it not only causes a huge waste of resources, but also the discarded corrugated cardboard boxes are difficult to degrade in the natural environment. According to the search, the existing patent (publication number: CN215611856U) discloses a corrugated cardboard box cutting waste recycling and crushing device, including a feeding hopper and a crushing roller. The crushing roller is equipped with a crushed material transport mechanism at the bottom. The coarse material box is equipped with a circulating conveying mechanism that transports large waste materials back to the feeding hopper. The circulating conveying mechanism includes a chain, sprockets, and a shovel. The shovel is fixedly installed on the chain and is evenly distributed on the chain. The chain is guided by multiple sprockets to form an ascending part, a detour part, and a descending part. The lower ends of the ascending part and the descending part are placed in the coarse material box, and the upper ends of the ascending part and the descending part are connected to the detour part, which extends to the upper side of the feeding hopper. In the process of realizing this utility model, the inventors discovered the following problems with the prior art:

[0004] The existing corrugated cardboard box cutting waste recycling device can only achieve simple crushing in the later use of the above-mentioned patent. Because the crushing unit generates a lot of dust and debris when processing waste, the debris and dust are scattered into the air, which is not only difficult to collect, but also harmful to the health of the workers when these fine particles are inhaled, making it difficult to meet the subsequent high-quality processing requirements.

[0005] Therefore, a corrugated cardboard box cutting waste recycling device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a corrugated cardboard box cutting waste recycling device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard box cutting waste recycling device, comprising a collection box, a circular crushing cylinder on the upper surface of the collection box, a crushing square box on the upper surface of the circular crushing cylinder, a dust collection square box fixedly connected to the upper surface of the collection box, a secondary dust collection hood and a suction cylinder fixedly connected to the outer surface of the dust collection square box respectively, the secondary dust collection hood being connected to the circular crushing cylinder, a main dust collection hood being fixedly connected to the top of the suction cylinder and connected to the crushing square box, a filter screen being provided inside the dust collection square box, a filter element being fixedly connected to the bottom surface of the filter screen, a negative pressure cylinder being provided on the bottom surface of the dust collection square box, and a negative pressure fan being fixedly connected to the inner wall of the negative pressure cylinder.

Crushing discs arranged at equal intervals are fixedly connected to the outer surface of each rotating rod. A fixed circular plate is fixedly connected to the inner wall of the circular crushing cylinder. A rotary motor is fixedly connected to the bottom surface of the fixed circular plate. A circular rotating shaft is fixedly connected to the output end of the rotary motor. Crushing teeth arranged at equal intervals are fixedly connected to the outer surface of the circular rotating shaft. A conveying auger is fixedly connected to the upper part of the outer surface of the circular rotating shaft.

[0009] Preferably, a sealing cover is installed on the back of the dust collection box by screws.

[0010] Preferably, a guide hopper is fixedly connected to the inner wall of the circular crushing cylinder, and a discharge port is opened inside the guide hopper, and the discharge port is adapted to the size of the conveying auger.

[0011] Preferably, mounting blocks are fixedly connected to both the front and back of the collection box, and the outer surface of the mounting blocks is provided with round holes.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] Compared with existing technologies, this corrugated cardboard box cutting waste recycling device uses a drive motor on the crushing box to drive a rotating rod and a crushing disc, which can initially crush corrugated cardboard box cutting waste, breaking larger waste blocks into smaller sizes. The crushed waste is then transported downwards by a conveying auger on a circular rotating shaft. A rotating motor inside the circular crushing cylinder drives the circular rotating shaft to drive the crushing teeth to further crush and refine the waste. Through two-stage crushing, the waste can be crushed into finer particles that are more suitable for recycling and reuse, improving the quality of waste recycling and the convenience of subsequent processing, and achieving effective recycling and utilization of resources.

[0018] Compared with existing technologies, this corrugated cardboard box cutting waste recycling device uses a dust collection box and main and auxiliary dust collection hoods to cover the crushing box and circular crushing cylinder respectively. It can collect paper scraps and dust generated during the crushing process. Under the action of the negative pressure fan inside the dust collection box, the dust-laden air is drawn into the dust collection box.

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. Example

[0027] As attached Figures 1-6 The device for recycling corrugated cardboard box cutting waste includes a collection box 1, a circular crushing cylinder 2 on the upper surface of the collection box 1, a crushing square box 3 on the upper surface of the circular crushing cylinder 2, a dust collection square box 7 fixedly connected to the upper surface of the collection box 1, a secondary dust collection hood 11 and a dust suction cylinder 9 fixedly connected to the outer surface of the dust collection square box 7 respectively, the secondary dust collection hood 11 being connected to the circular crushing cylinder 2, the top of the dust suction cylinder 9 being fixedly connected to the main dust collection hood 10, and the main dust collection hood 10 being connected to the crushing square box 3, a filter screen 14 being provided inside the dust collection square box 7, a filter element 15 being fixedly connected to the bottom surface of the filter screen 14, a negative pressure cylinder 12 being provided on the bottom surface of the dust collection square box 7, and a negative pressure fan 13 being fixedly connected to the inner wall of the negative pressure cylinder 12.

[0028] Two drive motors 17 are fixedly installed on the outer surface of the crushing box 3 via the frame 16. Each drive motor 17 has a rotating rod 18 fixedly connected to its output end. Each rotating rod 18 has a crushing disc 19 arranged at equal intervals fixedly connected to its outer surface. A fixed circular plate 22 is fixedly connected to the inner wall of the circular crushing cylinder 2. A rotary motor 23 is fixedly connected to the bottom surface of the fixed circular plate 22. A circular rotating shaft 25 is fixedly connected to the output end of the rotary motor 23. Crushing teeth 27 arranged at equal intervals are fixedly connected to the outer surface of the circular rotating shaft 25. A conveying auger 26 is fixedly connected to the upper part of the outer surface of the circular rotating shaft 25.

[0029] As can be seen from the above description, this utility model has the following beneficial effects: By setting the drive motor 17 on the crushing box 3 to drive the rotating rod 18 and the crushing disc 19, the corrugated cardboard box cutting waste can be initially crushed, breaking larger waste blocks into smaller sizes. The auger 26 on the circular rotating shaft 25 can transport the crushed waste to the lower part. The rotating motor 23 inside the circular crushing cylinder 2 drives the circular rotating shaft 25 to drive the crushing teeth 27 to further crush and refine the initially crushed waste. Through two-stage crushing, the waste can be crushed to a size more suitable for recycling. The fine particles improve the quality of waste recycling. The dust collection box 7, main dust collection hood 10, and auxiliary dust collection hood 11 cover the crushing box 3 and the circular crushing cylinder 2 respectively, which can collect the paper dust generated during the crushing process. Under the action of the negative pressure fan 13 inside the dust collection box 7, the dust-laden air is drawn into the dust collection box 7. The filter screen 14 and filter element 15 filter the dust-laden air, effectively preventing the dust from spreading to the surrounding environment, improving the air quality of the workplace, helping to achieve efficient recycling of corrugated cardboard box cutting waste, improving the production environment, and ensuring production safety and stable operation of equipment. Example

[0030] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0031] like Figures 1-6 As shown, in a preferred embodiment, a sealing cover plate 8 is installed on the back of the dust collection box 7 by screws. A guide hopper 20 is fixedly connected to the inner wall of the circular crushing cylinder 2. The guide hopper 20 has a discharge port 21 inside, and the discharge port 21 is adapted to the size of the conveying auger 26. Mounting blocks 4 are fixedly connected to both the front and back of the collection box 1, and the outer surface of the mounting blocks 4 has round holes. Furthermore, by periodically opening the sealing cover plate 8, the dust collected in the dust collection box 7 can be cleaned, and the filter screen 14 and filter element 15 can be replaced or cleaned to ensure the normal operation of the dust collection system. This allows the conveying auger 26 to orderly transport the crushed waste material from the crushing area to the guide hopper 20, and then drop it into the lower circular crushing cylinder 2 through the discharge port 21 for further processing, ensuring the continuity of processing. The mounting blocks 4 facilitate the use of bolts and other connecting parts to install the entire device in a suitable location in the corrugated cardboard box production workshop.

[0032] like Figures 1-6As shown, in a preferred embodiment, an annular guide rail 28 is fixedly connected to the inner wall of the circular crushing cylinder 2. Two transmission rods 29 are slidably connected inside the annular guide rail 28. The end of each transmission rod 29 away from the annular guide rail 28 is fixedly connected to the outer surface of the circular rotating shaft 25. Two discharge ports 24 are opened on the upper surface of the fixed circular plate 22. A collection frame 5 is provided inside the collection box 1, and the collection frame 5 is located below the rotary motor 23. A feed hopper 6 is fixedly connected to the upper surface of the crushing box 3. The feed hopper 6 is inclined. Furthermore, through the stable operation of the circular rotating shaft 25 driven by the rotary motor 23, the transmission rods 29 rotate within the annular guide rail 28, reducing vibration and shaking, and ensuring the normal operation of the equipment. The discharge ports 24 facilitate the collection of crushed materials into the collection frame 5 for collection. Moreover, the feed hopper 6 makes it convenient for workers to pour corrugated cardboard box cutting waste into the device, improving the ease of operation.

[0033] The working process of this utility model is as follows:

[0034] When using this corrugated cardboard box cutting waste recycling device, first, the device is securely installed. The corrugated cardboard waste is then added to the crushing box 3 from the feed hopper 6. The two drive motors 17 are started, causing the two rotating rods 18 to rotate in opposite directions. The rotation of the crushing disc 19 then performs preliminary crushing of the added waste, breaking larger waste pieces into smaller sizes. Under the guiding action of the guide hopper 20, the rotary motor 23 is started, rotating the circular shaft 25. The conveying auger 26 rotates accordingly, which can orderly transport the waste crushed by the crushing disc 19 to the bottom of the guide hopper 20. The crushing teeth 27 can simultaneously crush the conveyed waste again as the circular shaft 25 rotates, achieving further crushing and refining of the waste after preliminary crushing. After two stages of crushing, the waste smoothly enters the collection frame 5 in the collection box 1 through the discharge port 21 and the discharge port 24.

[0035] During the crushing process, the negative pressure fan 13 is started to generate negative pressure. Under the action of the negative pressure fan 13, the dust in the crushing box 3 can be sucked out through the dust suction cylinder 9 and the main dust collection hood 10. The auxiliary dust collection hood 11 can also extract the dust in the circular crushing cylinder 2. The dust-laden air is sucked into the dust collection box 7 and filtered through the filter screen 14 and filter element 15. The clean air is discharged through the negative pressure cylinder 12, thus trapping the dust on the filter screen 14 and filter element 15 in the dust collection box 7. This effectively reduces the pollution of the workshop environment by dust and protects the health of the workers. This is the working process and working principle of the device.

[0036] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
