A device for recycling corrugated paperboard waste

Abstract

This utility model provides a device for recycling waste corrugated cardboard. It includes a processing bin and a feeding machine. The bottom of the processing bin is equipped with a waste compression mechanism, and the processing bin is connected to the waste compression mechanism via an auger feeding mechanism. A screen plate is installed inside the feeding machine, and a vibration pump is mounted on the feeding machine. In this utility model, waste cardboard fragments can be vibrated and screened before feeding, thereby removing impurities and nails from the inside of the waste paper. During the impurity removal process, a magnetic rod is used to collect the nails. The screened waste cardboard fragments undergo a "crushing and grinding" process inside the processing bin, resulting in a high degree of fineness. This not only reduces the impurity rate in the finished product but also produces fine paper scraps after processing, making it a higher-quality material for recycling. Furthermore, this crushing and grinding process only requires one power source, reducing maintenance workload and expenses.

Description

Technical Field

[0001] This utility model relates to a waste recycling device, and in particular to a waste cardboard recycling device, belonging to the field of waste recycling technology. Background Technology

[0002] A corrugated cardboard waste recycling plant is a device specifically designed for recycling and reusing waste corrugated cardboard. Through processing and refining, waste cardboard can be transformed into reusable raw materials.

[0003] CN222428177U discloses a corrugated cardboard waste cleaning device, relating to the field of waste cleaning technology. The device includes a cleaning box, inside which is a pulverizing tank. A grinding box is located at the lower end of the pulverizing tank, and a guiding device is provided between the pulverizing tank and the grinding box. A discharge pipe is located inside the lower end of the cleaning box. This device uses a feeding device to add cardboard waste into the pulverizing tank. A stirring motor inside the pulverizing tank drives multiple sets of pulverizing blades to cut and pulverize the cardboard waste. Two drive motors rotate a guide plate to facilitate the conveying of the pulverized cardboard waste into the grinding box. A grinding motor drives a main grinding roller to rotate. The mutual rotation between the main grinding roller and the auxiliary grinding roller grinds the cardboard waste. The discharge pipe facilitates the recycling of the ground cardboard waste.

[0004] However, during the cardboard feeding process, the device is expected to contain some impurities and iron objects such as nails. This not only results in a high impurity rate in the shredded paper scraps, but the presence of nails also wastes resources and affects subsequent paper scrap processing. Furthermore, the device requires one motor for shredding, two motors for driving the guide plate below, and two more motors for grinding. This significantly increases procurement costs and makes subsequent maintenance difficult and expensive, thus requiring improvement.

[0005] Therefore, a device for recycling waste corrugated cardboard is proposed. Summary of the Invention

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1-7 As shown in the figure, this utility model embodiment provides a waste corrugated cardboard recycling device, including a processing bin 1 and a feeding machine 2. The bottom of the processing bin 1 is provided with a waste compression mechanism, and the processing bin 1 is connected to the waste compression mechanism through an auger feeding mechanism. A screen plate 3 is installed inside the feeding machine 2, a vibration pump 4 is installed on the feeding machine 2, a chip plate 5 is installed inside the feeding machine 2, the chip plate 5 is located below the screen plate 3, and a groove plate 6 is installed inside the feeding machine 2, with a matching magnet installed in the groove plate 6. A connecting plate 8 is installed on one side of the magnetic rod 7. A servo motor A9 is installed above the processing chamber 1. A rotating shaft 10 is installed at the output end of the servo motor A9. A crushing blade 11 is installed on the rotating shaft 10. An intercepting plate 12 is installed inside the processing chamber 1. A vertical through groove is provided in the intercepting plate 12 to allow the rotating shaft 10 to pass through. An umbrella-shaped plate 13 is installed on the rotating shaft 10. A rotating grinding roller 14 is rotatably installed on the umbrella-shaped plate 13. An annular grinding disc 15 is installed on the inner wall of the processing chamber 1.

[0030] In one embodiment, the auger feeding mechanism includes a cylinder 16, a servo motor B17, and a reamer 18. The cylinder 16 is connected below the processing chamber 1, the servo motor B17 is installed at one end of the cylinder 16, and the reamer 18 is installed at the output end of the servo motor B17. When the servo motor B17 is started, it drives the reamer 18 to rotate, and the reamer 18 conveys the refined paper scraps inside the processing chamber 1.

[0031] In one embodiment, the waste compression mechanism includes a collection chamber 19, an opening and closing plate 20, a waste trough 21, a cylinder 22, and a pressing plate 23. The collection chamber 19 is connected to the side end of the cylinder body 16. The opening and closing plate 20 is rotatably mounted on the collection chamber 19. The cylinder 22 is mounted behind the collection chamber 19, and the pressing plate 23 is mounted at the output end of the cylinder 22. Activating the cylinder 22 causes the pressing plate 23 to slide along the collection chamber 19, pushing and compressing the paper scraps in the process, thereby compressing them into blocks and improving transportation efficiency.

[0032] In one embodiment, the feeder 2 has a through slot for mounting the magnet rod 7, and the connecting plate 8 and the feeder 2 are connected by bolts. The fixing between the connecting plate 8 and the feeder 2 can be released by rotating the bolts on the connecting plate 8, and then the magnet rod 7 can be pulled out along the slot plate 6, thereby collecting the iron nails on the magnet rod 7.

[0033] In one embodiment, the rotating shaft 10 rotates within the processing chamber 1 via bearings. During the rotation of the rotating shaft 10, it drives the crushing blade 11 and the umbrella-shaped plate 13 to rotate simultaneously.

[0034] In one embodiment, a feed hole is provided on the side of the collecting chamber 19, and the diameter of the feed hole is the same as the diameter of the cylinder body 16. This enables the rapid conveying of paper scraps from inside the processing chamber 1 to the inside of the collecting chamber 19.

[0035] In one embodiment, the waste material trough 21 is located at the bottom of the collection chamber 19, and the opening and closing plate 20 is closed to the collection chamber 19 by means of a pin. As the extrusion plate 23 slides back along the collection chamber 19, it can push some of the paper scraps falling from the cylinder 16 in the opposite direction and finally discharge them through the waste material trough 21, thus avoiding the accumulation of waste material.

[0036] In operation, this invention works as follows: First, waste cardboard is cut into pieces and fed into the feeder 2. Then, the vibration pump 4 is started, and under the action of vibration, the waste cardboard above moves along the screen plate 3. During this process, under the action of vibration, some impurities and nails inside the cardboard are screened off and fall through the holes of the screen plate 3. At this time, the impurities fall vertically onto the shredder plate 5 below. During the falling process, the nails are attracted by the magnet rod 7 and adsorbed on the surface of the magnet rod 7. At this time, the fixing between the magnet rod 7 and the feeder 2 can be released by rotating the bolt on the connecting plate 8. Then, the magnet rod 7 can be pulled out along the groove plate 6, and the nails on the magnet rod 7 can be collected. Under the action of the servo motor A9, the rotating shaft 10 can be rotated, so as to work with the crusher blade 11 to quickly shred the waste cardboard that has entered the processing chamber 1. When the shredded cardboard is of sufficient size... When passing through the interceptor plate 12, the rotating shaft 10 will drive the umbrella-shaped plate 13 to rotate, and the rotating grinding roller 14 will cooperate with the annular grinding disc 15 surrounding it to grind the paperboard. This successfully achieves the effect of first shredding and then grinding, further improving the processing fineness of the paperboard. The servo motor B17 is started and drives the scissor 18 to rotate. Under the action of the scissor 18, the finely ground paper scraps inside the processing chamber 1 will be conveyed and enter the collection chamber 19 through the cylinder 16. Then, the cylinder 22 is started and drives the extrusion plate 23 to slide along the collection chamber 19. During this process, the paper scraps are pushed and squeezed, which can compress them into blocks and improve the transportation efficiency. Then, the pin is pulled out and the opening and closing plate 20 is opened along the collection chamber 19. At this time, under the action of gravity, the "paper scrap blocks" inside the collection chamber 19 will fall out.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
