Description

Technical Field

[0001] The utility model relates to the technical field of paper shredding equipment, and particularly to an energy-efficient waste paper belt shredder. Background Art

[0002] In the production process of cardboard, steps such as pulping, papermaking, and processing are generally required. Among them, the processing step is further divided into processing techniques such as cutting, embossing, printing, and laminating to meet the needs of different customers. During the processing, it is necessary to determine appropriate processing methods and process parameters according to the requirements of customers to ensure that the quality and appearance of cardboard products meet the requirements. A large amount of waste paper belts will be generated during the cutting process. In order to make these waste paper belts reusable, the usual treatment method is to crush the waste paper belts and then pack them through a packing device. However, the existing paper shredding equipment has low efficiency and cannot meet the production capacity of the factory. The structure is relatively complex and the energy efficiency is high. When processing a large number of waste paper belts, it is easy to cause the phenomenon of the paper shredding equipment getting stuck.

[0003] For example, the Chinese patent of publication CN118179687A discloses a paper shredder with complete shredding, including a machine body. A cavity is opened in the machine body. Two first rotating shafts are horizontally and rotatably installed in the shredding cavity. Transverse shredding cutter rollers are fixedly sleeved on the first rotating shafts. A driving motor is fixedly installed on the surface of the machine body. The output shaft of the driving motor is fixedly connected to one of the first rotating shafts. First gears are fixedly sleeved on both the output shaft of the driving motor and one of the first rotating shafts. An installation plate is fixedly installed in the machine body. A plurality of second rotating shafts are vertically and rotatably installed on the installation plate. Vertical shredding cutter rollers are fixedly sleeved on the second rotating shafts. When the paper is shredded into thin strips by the transverse shredding cutter rollers, it will be shredded again by the vertical shredding cutter rollers, so that the thin strip-shaped paper can be shredded into paper scraps, and the shredding of the paper is more complete. The shredded paper cannot be restored, avoiding the leakage of confidential documents.

[0004] In the above solution, the waste paper needs to be shredded twice by using vertical shredding cutter rollers and transverse shredding cutter rollers to shred the paper. Its shredding efficiency is low. When a large amount of waste paper passes through the transverse shredding cutter rollers or the vertical shredding cutter rollers, it is easy to cause the corresponding shredding cutter rollers to get stuck.

[0005] For another example, a Chinese patent with the publication number CN220027261U discloses a paper shredder, which includes an upper cover and a lower box body. A first guide plate and a second guide plate are arranged in the lower box body. The first guide plate and the second guide plate are arranged opposite to each other to form a paper shredding channel. Multiple groups of paper shredding blades are arranged on both the first blade shaft and the second blade shaft. Two adjacent paper shredding blades on the two blade shafts are engaged with each other to form a cutting opening; on the side of the first guide plate close to the second guide plate, there are multiple first paper guiding ribs arched, and on the side of the second guide plate close to the first guide plate, there are multiple second paper guiding ribs arched. One first paper guiding rib and one second paper guiding rib are arranged on both sides of each cutting opening. The paper shredder provided by the present invention adopts the first paper guiding ribs and the second paper guiding ribs which are staggered on both sides of the paper shredding channel to stagger the strip-shaped shredded paper cut by the paper shredding blades, avoiding entanglement between shredded papers and causing paper jams; a first guiding channel and a second guiding channel are arranged on the paper shredder to guide the strip-shaped shredded paper to avoid the reinforcing plate, avoiding paper jams.

[0006] In the above solution, the phenomenon of paper jams is avoided by setting the first paper guiding ribs and the second paper guiding ribs. When facing a long waste paper tape, the long paper tape may pass through between the paper shredding blades of two adjacent pieces and cannot effectively cut the long paper tape or the cutting is not thorough.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0027] Please refer to Figure 1-6 As shown, the high-efficiency and energy-saving waste paper tape shredder of the present utility model includes a frame 01. A box body 02 is installed on the frame 01 by welding or fasteners. A paper feeding component 03 and a conveying component 04 are arranged on the box body 02. The paper feeding component 03 is located at the upper part on one side of the box body 02 and is connected to the box body 02 in a penetrating manner. The conveying component 04 is located at the bottom of the box body 02 and is connected to the box body 02 in a penetrating manner. A roller component 05 is rotatably installed in the box body 02. A plurality of receiving grooves 06 are evenly distributed on the surface of the roller component 05, and the receiving grooves 06 are connected to the paper feeding component 03 in a penetrating manner. A cutting component 07 for shredding the waste paper tape in the receiving groove 06 is arranged on the outer surface of the box body 02.

[0028] During use, under the action of the paper feeding component 03, the waste paper tape is conveyed into the receiving groove 06 of the drum component 05. When the drum component 05 rotates, the waste paper in the receiving groove 06 is rotated towards the cutting component 07. After the cutting component 07 cuts the waste paper in the receiving groove 06, the drum component 05 continues to rotate, and the cut waste paper is rotated towards the conveying component 04 of the box body 02. When the cut waste paper is directly above the conveying component 04, the waste paper falls into the conveying component 04. Under the action of the conveying component 04, the cut waste paper is conveyed out of the box body 02.

[0029] Please refer to Figure 2 As shown, the paper feeding component 03 includes a feeding port 08 provided on one side of the box body 02 and a paper feeding fan. The paper feeding fan is preferably a centrifugal fan, and the installation position of the paper feeding fan is determined according to the actual situation. The installation position of the paper feeding fan is not limited here. The feeding port 08 is connected to the receiving groove 06 in a through manner and is on the same horizontal plane. A feeding pipe 09 is fixedly installed at the feeding port 08, and the inlet of the feeding pipe 09 is connected to the outlet of the paper feeding fan through an air duct. The positive pressure air flow generated when the paper feeding fan works is discharged from the outlet. Under the action of the positive pressure air flow, the waste paper tape enters the box body 02 from the feeding pipe 09.

[0030] One end of the feeding pipe 09 is provided with a plurality of feeding pipes 10, and a paper feeding fan is installed on each feeding pipe 10 through an air duct. Therefore, multiple waste paper tape sources can simultaneously convey waste paper tapes into the box body.

[0031] Please refer to Figure 2 As shown, the conveying component 04 includes a discharge port provided at the bottom of the box body 02 and a paper suction fan 12. The paper suction fan 12 is preferably a centrifugal fan, and the installation position of the paper suction fan 12 is determined according to the actual situation. The installation position of the paper suction fan 12 is not limited here. The discharge port is connected to the box body 02 in a through manner. A discharge pipe 11 is fixedly installed at the discharge port, and the outlet of the discharge pipe 11 is connected to the suction port of the paper suction fan 12 in a through manner. The negative pressure air flow generated when the paper suction fan 12 works discharges the cut waste paper tape in the discharge pipe 11 out of the box body 02. It should be noted that after the waste paper in the discharge pipe 11 is discharged out of the box body 02 under the action of the paper suction fan 12, the cut waste paper can be processed by external dust removal equipment and packaging equipment, and the dust can also be processed.

[0032] When the paper feeding component 03 is working, the positive pressure airflow generated will transport the waste paper belt into the box 02. In the process of transporting the waste paper belt, the positive pressure airflow generated by the paper feeding component 03 will also enter the box 02. Similarly, when the conveying component 04 is working, the negative pressure airflow generated will discharge the waste paper at the bottom of the box 02 to the outside of the box 02. In the process of discharging the waste paper, the negative pressure airflow generated by the conveying component 04 will discharge the air in the box 02. Therefore, when the paper feeding component 03 and the conveying component 04 work synchronously, the air in the box 02 is in a flowing state, although the receiving groove 06 is provided on the surface of the roller component 05, so that the air flows in the receiving groove 06.

[0033] An air passage 13 is provided between the roller component 05 and the side wall of the box body 02, and is connected to the conveying component 04. The air passage 13 and the paper feeding component 03 are located on both sides of the roller component 05. One end of the receiving slot 06 is connected to the air passage 13, and the other end of the receiving slot 06 is connected to the paper feeding component 03. When the conveying component 04 and the paper feeding component 03 are working, air enters the box body 02 from the paper feeding component 03, and then passes through the receiving slot 06 and the air passage 13 in sequence and is discharged from the conveying component 04 to the outside of the box body 02 (as shown in 2); the air in the box body 02 is in a flowing state.

[0034] Therefore, during use, when the waste paper tape enters the receiving groove 06 on the roller component 05, the roller component 05 rotates synchronously in the box body 02, and the paper feeding component 03 and the conveying component 04 work synchronously, so that the air in the box body 02 flows in the receiving groove 06 and the air channel 13. When the air in the receiving groove 06 flows, the state of the waste paper tape in the receiving groove 06 is changed into a "V" shape or a "W" shape.

[0035] When the waste paper tape enters the receiving slot 06 under the action of the paper feeding component 03, the paper feeding component 03 uses the positive pressure airflow to provide thrust for the waste paper tape in the process of conveying the waste paper tape. The airflow generates thrust acting on the edge of the waste paper tape, while the center of the waste paper tape is relatively fixed. This thrust causes the edge of the paper tape to bend forward, forming a shape similar to a V or W shape. However, while the paper feeding component 03 is working, the conveying component 04 is also working synchronously, so that the air in the receiving slot 06 is in a flowing state, and the air in the receiving slot 06 flows. However, while the roller component 05 is rotating, the airflow in the receiving slot 06 is in an unstable state. As a result, the paper tape is subjected to irregular forces in the receiving slot 06, so that the waste paper tape is bent or twisted in the receiving slot 06. As a result, the waste paper tape is formed into a shape similar to a V or W shape. However, by making the air in the receiving slot 06 flow, in addition to making the waste paper tape in the receiving slot 06 V-shaped or W-shaped. (As shown in 3) At the same time, the waste paper belt can be spread horizontally over the entire receiving slot 06 under the action of air flow.

[0036] It should be noted that by selecting different models of the paper feeding fan and the paper sucking fan 12, and at the same time by controlling the rotational speeds of the paper feeding fan and the paper sucking fan 12 during operation, the flow rate of the air inside the box body 02 can be controlled, so as to prevent the waste paper belt in the receiving groove 06 from entering the air passage 13 under the action of the air. For those skilled in the art, how to select the power of the paper feeding fan and the paper sucking fan 12 and control the rotational speeds of the paper feeding fan and the paper sucking fan 12 belongs to the prior art and will not be elaborated here.

[0037] Please refer to Figure 4 As shown in the figure, an air inlet 14 is provided on one side of the box body 02. The air inlet 14 is located below the feed pipe 09 and is connected to the discharge pipe 11 in a through manner. A wind door 15 is provided at the air inlet 14. A fixing rod 16 is provided on the outer surface of the box body 02. The fixing rod 16 is preferably a screw rod. A strip-shaped hole 17 adapted to the fixing rod 16 is provided on the wind door 15. So that the wind door 15 can move along the fixing rod 16, thereby enabling the wind door 15 to change the area of the air inlet 14, and thus controlling the air flow rate entering the box body 02 from the air inlet 14.

[0038] During actual use, the negative pressure air flow generated during the operation of the conveying component 04 discharges the waste paper in the discharge pipe 11 outside the box body 02. However, when the paper feeding component 03, the conveying component 04, and the cutting component 07 are installed on the box body 02, the inside of the box body 02 is in a sealed state. The negative pressure air flow generated during the operation of the conveying component 04 causes the air inside the box body 02 to enter together. However, the air entering the box body 02 is only provided by the paper feeding component 03. But the amount of air conveyed into the box body 02 by the paper feeding component 03 is less than or equal to the discharge amount of the air discharged from the box body 02 by the conveying component 04 during operation. When the amount of air entering the box body 02 is less than the amount of air discharged from the box body 02, the wind door 15 is opened, and the air in the atmosphere enters the box body 02 through the air inlet 14 to make up for the air amount inside the box body 02.

[0039] Therefore, during use, control the opening and closing degree of the wind door 15 according to the actual situation, so as to control the opening area of the air inlet 14. While ensuring the air pressure balance inside the box body 02, it can also make the air in the box body 02 in the receiving groove 06 and the air passage 13 in a flowing state. At the same time, it can also control the flow rate of the air in the receiving groove 06 and the air passage 13. So that the waste paper belt can horizontally cover the entire receiving groove 06.

[0040] Please refer to Figure 5 As shown in the figure, the roller component 05 includes two relatively arranged bearing seats one 18 fixedly installed on the frame 01. A roller shaft 19 is arranged between the two bearing seats one 18. A motor one 20 is arranged on the frame 01. The motor one 20 and the roller shaft 19 are connected by a chain drive, so that the roller shaft 19 rotates inside the box body 02.

[0041] On the outer surface of the roller shaft 19, a number of baffles 21 are fixedly installed by welding. The baffles 21 are evenly distributed on the outer surface of the roller shaft 19 and are arranged parallel to the axis of the roller shaft 19. The above-mentioned receiving groove 06 is formed between two adjacent baffles 21. The waste paper belt enters the receiving groove 06 from the feed port 08. When the roller shaft 19 rotates, the waste paper belt located in the receiving groove 06 is rotated towards the cutting member 07, and when the cutting member 07 works, it cuts the waste paper belt in the receiving groove 06. Since the receiving volume of the receiving groove 06 is fixed. It is equivalent to the roller component 05 moving the waste paper belt to be cut towards the cutting assembly in a single batch, and the cutting member 07 also cuts in a single batch when working. Compared with traditional crushing equipment, the load of the cutting member 07 is relatively balanced each time it cuts, thus avoiding the phenomenon that excessive waste paper causes too large a load on the cutting member 07 and the cutting member 07 being stuck.

[0042] Between two adjacent baffles 21, an arc plate 22 coaxial with the roller shaft 19 is fixedly connected by welding. A number of cutting grooves 23 are provided on both the arc plate 22 and the baffle 21. The cutting grooves 23 are arranged along the radial direction of the roller shaft 19, and the cutting grooves 23 extend between the outer surface of the arc plate 22 and the roller shaft 19. The distance between two adjacent cutting grooves 23 is the length after the waste paper belt is cut. That is, any waste paper can be cut once, which is simpler in structure and higher in efficiency compared with traditional shredders. At the same time, the cutting grooves 23 extend between the outer surface of the arc plate 22 and the roller shaft 19.

[0043] Please refer to Figure 6 As shown in the figure, the cutting member 07 includes two bearing seats two 24 provided on the box body 02. A cutting shaft 25 is provided between the two bearing seats two 24. The frame 01 is fixedly installed with a motor two 26. The motor two 26 and the cutting shaft 25 are driven by a chain to make the cutting shaft 25 rotate on the bearing seats two 24. The cutting shaft 25 is arranged parallel to the roller shaft 19. The same number of cutting blades 27 as the cutting grooves 23 are fixedly installed on the cutting shaft 25. A slot 28 adapted to the cutting blade 27 is provided on the box body 02. The cutting blade 27 passes through the slot 28 and is located in the cutting groove 23, and the outer edge of the cutting blade 27 is located between the outer surface of the arc plate 22 and the roller shaft 19. When the cutting blade 27 cuts the waste paper, it can ensure that each piece of waste paper can be completely cut off and will not damage the roller shaft 19.

[0044] A protective cover 29 is also provided on the outer surface of the box body 02. The protective cover 29 is fixedly installed on the outer surface of the box body 02 through fasteners and covers the cutting member 07. It avoids the dust diffusing into the air from the slot 28 when the cutting blade 27 works. It not only plays a sealing role but also prevents external objects from contacting the cutting blade 27. It improves the stability of the whole equipment.

[0045] When the utility model is in use, the conveying component 04, the paper feeding component 03, the roller component 05 and the cutting component 07 operate simultaneously. When the conveying component 04 and the paper feeding component 03 work simultaneously, the air in the box body 02 flows away from the paper feeding component 03. When the waste paper tape enters the receiving groove 06 of the roller component 05 in the box body 02 under the action of the paper feeding component 03, the waste paper tape in the receiving groove 06 moves away from the feeding component under the action of the air and forms a "V" shape or a "W" shape in the receiving groove 06 during the movement. The roller component 05 transfers the waste paper tape in the receiving groove 06 towards the cutting component 07, and the cutting component 07 cuts the waste paper tape in each receiving groove 06. Since the waste paper tape forms a "V" shape or a "W" shape in the receiving groove 06, the cutting component 07 cuts the waste paper tape into waste paper segments each time it cuts. The waste paper tape after cutting still remains in the receiving groove 06, the rolling component continues to rotate, transfers the waste paper segments above the conveying component 04, and the waste paper segments fall into the conveying component 04 under the action of gravity and are discharged out of the box body 02 by the conveying component 04, realizing the crushing of the waste paper tape. Since the utility model transfers the waste paper tape in the box body 02 to the cutting component 07 for cutting through the roller component 05, and at the same time, the roller component 05 and the frame 01 are connected by the bearing seat 18, a relatively small power motor 20 can drive the roller component 05 to rotate around the bearing seat. At the same time, when the cutting component 07 cuts the waste paper tape, it only cuts the waste paper tape in the receiving groove 06 on the roller component 05, and the number of waste paper tapes carried by the receiving groove 06 is limited. Therefore, a relatively small power motor 26 can also realize the cutting of the waste paper tape in the receiving groove 06. However, for traditional paper shredders, a large amount of waste paper tapes are piled up above the shredding rollers. When the shredding rollers rotate, they not only drive the waste paper tapes to move but also shred the waste paper tapes, and the motors used have higher power. At the same time, there will also be paper jamming phenomena.

[0046] If there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0047] The above embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model should fall within the protection scope determined by the claims of the present utility model.
