Description

Technical Field

[0001] The utility model relates to the technical field of paper shredding equipment, in particular to an energy-saving and environment-friendly paper shredder. Background Technique

[0002] The main function of a paper shredding and pulverizing machine is to shred recycled paper products. There are also small paper shredders used in companies to prevent competitors from obtaining business information from documents, so some documents of the company are shredded. At present, some paper shredding and pulverizing machines mostly cut paper by the mutual shearing and rolling of two roller shafts. The shredded paper is discharged through the outlet at the bottom. However, during the use process, waste paper is shredded between the two roller shafts. In actual application, when a large amount of waste paper accumulates between the two roller shafts, the phenomenon of the two roller shafts being stuck easily occurs. Since the distance between the two roller shafts and the feeding port is relatively small, the dust generated during the paper shredding process of the two roller shafts directly diffuses into the air from the feeding port, causing air pollution. At the same time, using two roller shafts to shred paper easily produces long paper strips. To shred the long paper strips, two mutually perpendicular roller shafts need to be arranged below the two roller shafts. Such a structure further reduces the shredding efficiency and increases the production cost of the equipment. Content of the Utility Model

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Please refer to Figures 1-3 As shown, the energy-saving and environment-friendly paper shredder of the present invention includes a frame 01. A circular arc-shaped hollow housing 02 is installed on the frame 01 by welding or fasteners. A feed inlet 03 and a discharge outlet 04 are provided on the housing 02. The discharge outlet 04 is provided at the bottom of the housing 02 and is connected to the housing 02 in a through manner. A cutting component 05 is provided on the outer surface of the housing 02. A drum component 06 is provided inside the housing 02 for carrying the waste paper to be cut in a single batch towards the cutting component direction and carrying the cut waste paper towards the discharge outlet 04 direction. A dust suction component for discharging the dust generated during the feeding and cutting of the waste paper out of the housing 02 is provided on one side of the housing 02.

[0020] During the use process, the waste paper enters the housing 02 from the feed inlet 03. The drum component 06 of the housing 02 carries the waste paper to be cut towards the cutting component 05. When the waste paper rotates to the cutting component 05, the cutting component 05 cuts the waste paper to be cut carried by the drum component 06. After the cutting component finishes cutting, the drum component 06 carries the cut waste paper towards the discharge outlet 04 of the housing 02. When the cut waste paper moves above the storage port, the cut waste paper falls out of the discharge outlet 04 under the action of gravity and drops outside the housing 02. The waste paper is transferred through an external transportation device. The dust generated during the feeding and cutting of the waste paper is discharged outside the housing 02 through the dust suction component, and the dust is centrally processed through an external dust removal device. Thereby, it is avoided that a large amount of dust generated by the cutting component 05 during the cutting of the waste paper drifts in the air and pollutes the air.

[0021] Please refer to Figure 1As shown in the figure, the dust suction component includes a dust outlet 07 and a centrifugal fan 08. The dust outlet 07 is arranged on one side of the housing 02. The dust outlet 07 and the air inlet of the centrifugal fan 08 are connected through a duct 09. After the centrifugal fan 08 is started, the air in the housing 02 flows. The dust located in the housing 02 follows the direction of the air flow and enters the duct 09 from the dust outlet 07, and finally is discharged from the air outlet of the centrifugal fan 08. Thus, it is avoided that a large amount of dust generated by the cutting component 05 when cutting waste paper drifts in the air and pollutes the air. At the same time, an external dust removal device can be connected to the air outlet of the centrifugal fan 08 for treating the dust.

[0022] It should be noted that by selecting an appropriate power of the centrifugal fan 08 and controlling the rotation speed of the centrifugal fan 08 during operation, the air flow rate in the housing 02 can be controlled, and it is avoided that the waste paper in the housing 02 is discharged out of the housing 02 under the action of the centrifugal fan 08. In other words, the suction force generated by the centrifugal fan 08 can only take away the dust in the housing 02, but cannot take away the waste paper in the housing 02. How to select the power of the centrifugal fan 08 and control the rotation speed of the centrifugal fan 08 by those skilled in the art belongs to the prior art and will not be elaborated here.

[0023] Please refer to Figure 2 As shown in the figure, the drum component 06 includes two relatively arranged bearing seats 10 fixedly installed on the frame 01. A roller shaft 11 is arranged between the two bearing seats 10. A first motor 12 is arranged on the frame 01. The first motor 12 and the roller shaft 11 are connected by a chain drive, so that the roller shaft 11 rotates in the housing 02. A number of baffles 13 are fixedly installed on the outer surface of the roller shaft 11 by welding. The a number of baffles 13 are evenly distributed on the outer surface of the roller shaft 11 and are arranged parallel to the axis of the roller shaft 11. A receiving groove 14 is formed between two adjacent baffles 13. Waste paper enters the receiving groove 14 from the feeding port 03. When the roller shaft 11 rotates, the waste paper located in the receiving groove 14 is rotated towards the cutting component 05, and the cutting component 05 cuts the waste paper in the receiving groove 14 during operation. Since the receiving volume of the receiving groove 14 is fixed, it is equivalent to that the drum assembly moves the waste paper to be cut towards the cutting assembly in a single batch, and the cutting group 05 also cuts in a single batch during operation. Compared with the traditional crushing equipment, the load of the cutting component 05 during each cutting is relatively balanced, thus avoiding the phenomenon that the cutting component 05 is overloaded and jammed due to too much waste paper.

[0024] Between two adjacent baffles 13, an arc plate 15 coaxial with the roller shaft 11 is fixedly connected by welding. A plurality of cutting grooves 16 are provided on both the arc plate 15 and the baffle 13. The cutting grooves 16 are arranged radially along the roller shaft 11 and extend between the outer surfaces of the arc plate 15 and the roller shaft 11. The distance between two adjacent cutting grooves 16 is the length after the waste paper 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 16 extend between the outer surfaces of the arc plate 15 and the roller shaft 11.

[0025] Please refer to Figure 3 As shown in the figure, the cutting component 05 includes two bearing seats 10 arranged on the housing 02. A cutting shaft 17 is provided between the two bearing seats 10. The frame 01 is fixedly installed with a second motor 18. The second motor 18 and the cutting shaft 17 are driven by a chain to make the cutting shaft 17 rotate on the bearing seats 10. The cutting shaft 17 is arranged parallel to the roller shaft 11. The same number of cutting blades 19 as the cutting grooves 16 are fixedly installed on the cutting shaft 17. A slot 20 adapted to the cutting blade 19 is provided on the housing 02. The cutting blade 19 passes through the slot 20 and is located in the cutting groove 16, and the outer edge of the cutting blade 19 is located between the outer surfaces of the arc plate 15 and the roller shaft 11. When the cutting blade 19 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 11.

[0026] A protective cover 21 is also provided on the outer surface of the housing 02. The protective cover 21 is fixedly installed on the outer surface of the housing 02 through fasteners and covers the cutting component 05. It can prevent dust from diffusing into the air from the slot 20 when the cutting blade 19 is working. While playing a sealing role, it can also prevent external objects from contacting the cutting blade 19. It improves the stability of the whole equipment.

[0027] The feeding port 03 is arranged on the side of the housing 02 and is opposite to the dust outlet 07. The feeding port 03 is connected to the receiving groove 14 in a through manner and is on the same horizontal plane. A feeding pipe is fixedly installed at the feeding port 03. In the actual use process, the waste paper is conveyed into the feeding pipe by a paper feeding fan. Since the waste paper has an initial velocity when entering the feeding pipe, and the paper feeding fan also provides a certain thrust, the waste paper can smoothly enter the receiving groove 14. It should be noted that the thrust provided by the paper feeding fan for the waste paper in the feeding pipe and the receiving groove 14 is adjusted according to the actual situation on site.

[0028] Another setting method of the feeding port 03 is that the feeding port 03 is arranged on the arc surface of the housing 02 and is perpendicular to the receiving groove 14. A feeding pipe is provided on the feeding port 03. When the waste paper is in the feeding pipe, the waste paper automatically falls into the receiving groove 14 by gravity.

[0029] When the utility model is in use, waste paper enters the receiving groove 14 on the roller 11 from the feed pipe. The first motor 12, the second motor 18 and the centrifugal fan 08 are started simultaneously. The first motor 12 drives the roller 11 to rotate in the housing 02, so that the waste paper in the receiving groove 14 rotates towards the cutting member 05. The second motor 18 drives the cutting blade 19 on the cutting shaft 17 to rotate in the cutting groove 16. When the waste paper in the receiving groove 14 contacts the cutting blade 19, the cutting blade 19 cuts up the waste paper. The shredded waste paper still remains in the receiving groove 14. The roller 11 continues to rotate, and the shredded waste paper in the receiving groove 14 is rotated towards the discharge port 04. The shredded waste paper is discharged out of the housing 02 from the discharge port 04 under the action of gravity. During the operation of the cutting member 05 and the drum member 06, the centrifugal fan 08 is started, and the dust floating in the housing 02 is discharged out of the housing 02 under the action of the centrifugal fan 08. Thus, it is avoided that the dust generated when the cutting member 05 works floats in the air and pollutes the air.

If the specific posture changes, the directional indications will also change accordingly.

[0031] 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 engineering and technical personnel in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
