Description

Technical Field

[0001] The utility model relates to the technical field of pulverizing fans, in particular to a novel aluminum foil trimming and pulverizing fan. Background Art

[0002] In order to facilitate the recycling of battery aluminum foil trimming waste, the battery aluminum foil trimmings need to be cut off. However, the existing crushing blower is only equipped with blades on the impeller blades, so it can only trim the double-zero foil. Double-zero foil is an aluminum foil material with a thickness of less than 0.01 mm, and the thickness of battery aluminum foil is greater than double-zero foil, so the existing crusher is often unable to completely cut the battery aluminum foil. Since the battery aluminum foil cannot be completely cut off, it cannot be discharged from the bellows outlet, the crushing effect is not good, and the battery aluminum foil trimmings are easily blocked in the bellows, resulting in this case. Utility Model Content

[0003] The utility model aims to provide a novel aluminum foil trimming and crushing fan, which has better crushing effect and is not easy to cause blockage to the bellows.

Each blade is connected to the rotating shaft and extends radially along the rotating shaft. The inner side of the blade is connected to the base. A blade wind knife is fixed on the outer side of the blade. The blade wind knife forms a wind knife edge facing the rotation direction of the impeller.

[0006] The bellows is provided with a feed inlet and a discharge outlet, the impeller is rotatably arranged in the bellows, the central axis of the feed inlet coincides with the axis of the rotating shaft and is located on one side of the blade wind knife, and the discharge outlet is arranged on the side wall of the bellows;

[0007] The annular wind knife is arranged at the feed inlet and has an annular structure. An annular cutting edge is formed on the inner ring along the circumference and is spaced apart from the blade wind knife.

[0008] Furthermore, the middle portion of the impeller base extends and bulges toward the feed inlet to form a first cone.

[0009] Furthermore, it also includes a guide cover, which is installed on the feed port. A feed channel is provided on the guide cover. The inner end of the feed channel is connected to the feed port, and the outer end protrudes outward to form a suction port. An annular air knife is arranged on the inner end of the feed channel.

[0010] Furthermore, the feed channel is contracted inwardly toward the feed port to form a second cone.

[0011] Furthermore, the interval between the annular wind knife and the blade wind knife is 5 mm.

[0012] Furthermore, the wind knife edge is inclined 30 degrees toward one side of the blade.

[0013] Furthermore, the annular cutting edge is inclined at 30 degrees toward one side of the feed channel.

[0014] Furthermore, the wind knife edge is a tooth-shaped structure.

[0030] like Figures 1 to 7 As shown, a novel aluminum foil trimming and crushing fan is used to crush the trimming of battery aluminum foil, including an impeller 1, a bellows 2 and an annular wind knife 3; the impeller 1 includes a base 4 and a rotating shaft 5 standing in the center of the base 4, and a plurality of blades 6 are arranged in an annular array around the rotating shaft 5 on the base 4, each blade 6 is connected to the rotating shaft 5 and extends radially along the rotating shaft 5, the inner side of the blade 6 is connected to the base 4, and a blade wind knife 7 is fixed to the outer side of the blade 6, and the blade wind knife 7 is formed with a wind knife edge 71 facing the rotation direction of the impeller 1; specifically, a receiving groove 17 is formed between two adjacent blades 6 and the base 4, and a plurality of blades 6 and the base 4 form a plurality of receiving grooves 17, which can facilitate the partitioning and transmission of the crushed battery aluminum foil without piling up together, and in addition, a card slot is formed on the outer side of the blade 6, and a card convex cooperating with the card slot is formed on the blade wind knife 7, and the card convex is inserted into the card slot to prevent the blade wind knife 7 from shaking, and the blade wind knife 7 and the blade 6 are fixed together by bolts.

[0031] The bellows 2 is provided with a feed port 8 and a discharge port 9. The feed port 8 is used for feeding the trimmed battery aluminum foil, and the discharge port 9 is used for conveying the crushed battery aluminum foil to an external recycling device (not shown in the drawings); the impeller 1 is rotatably arranged in the bellows 2, the central axis of the feed port 8 coincides with the axis of the rotating shaft 5 and is located on one side of the blade wind knife 7, and the discharge port 9 is arranged on the side wall of the bellows 2; combined with Figure 2 The bellows 2 is a cylindrical structure, and its side wall is an annular structure. The annular side wall and the annular surface formed by the rotation of the impeller 1 are concentrically arranged.

[0032] The annular wind knife 3 is arranged at the feed port 8 and has an annular structure. An annular cutting edge 31 is formed on its inner ring along the circumferential direction and is spaced apart from the blade wind knife 7. When the impeller 1 rotates at high speed, the blade wind knife 7 installed on the blade 6 also rotates at high speed and rotates relative to the annular wind knife 3, forming relative shearing with the annular wind knife 3, which can facilitate cutting the edges of the battery aluminum foil and crushing it to avoid blockage caused by the aluminum foil not being cut.

[0033] Furthermore, the number of blades 6 is six, and correspondingly, the number of blade wind knives 7 is also six, thereby forming six receiving grooves 17, which can disperse the crushed aluminum foil in the six receiving grooves 17, and transfer it to the discharge port 9 in sections after the impeller 1 rotates. It is not easy to pile up together, which is convenient for transportation.

[0034] It also includes a rotary drive mechanism 15 and a frame 16 . The rotary drive mechanism 15 and the bellows 2 are fixed on the frame 16 . The rotary drive mechanism 15 is connected to the impeller 1 shaft 5 to drive the impeller 1 to rotate around the shaft 5 .

[0035] Specifically, the frame 16 includes a base 161 and a support frame 162. The support frame 162 is fixed on the base 161. A first mounting port 163 for inserting and fixing the air box 2 and a second mounting port 164 for exposing the discharge port 9 are formed on the support frame 161. The size of the first mounting port 163 is adapted to the size of the outer contour of the air box 2, and the size of the second mounting port 164 is adapted to the size of the discharge port 9. The air box 2 is inserted into the support frame 162 through the first mounting port 163, and the discharge port 9 extends from the second mounting port 164, so that the air box is fixed on the support frame 162.

[0036] like Figure 2 As shown, the rotary drive mechanism 15 includes a motor 151, a transmission belt 152 and a transmission shaft 153. The transmission belt 152 connects the output end of the motor 151 and the input end of the transmission shaft 153, so that the output end of the motor 151 rotates through the transmission of the transmission belt 152 to drive the transmission shaft 153 to rotate; the bellows 2 is also provided with a mounting hole 21 for the transmission shaft 153 to be inserted and fixed to the impeller 1 shaft 5, so that when the output end of the motor 151 rotates, the transmission shaft 153 drives the impeller 2 to rotate around the axis.

[0037] In this specific embodiment, Figure 3 As shown, the middle part of the base 4 of the impeller 1 extends toward the feed port 8 to form a first cone 10, which is sent into the accommodating groove 17. After being guided and diffused by the inclined surface of the first cone 10, it can be easily transferred out without accumulating in the corners of the accommodating cavity 17.

[0038] In this specific embodiment, Figure 2 As shown, it also includes a guide cover 11, which is installed on the feed port 8. A feed channel 12 is provided on the guide cover 11. The inner end of the feed channel 12 is connected to the feed port 8, and the outer end protrudes outward to form a suction port 13. The annular air knife 3 is arranged on the inner end of the feed channel 12. Specifically, a through hole is formed on the annular air knife 3, and a bolt hole is formed on the inner end of the feed channel 12. The annular air knife 3 passes through the through hole with a bolt and is screwed on the bolt hole, so that the annular air knife 3 is fixed on the guide cover 11.

[0039] Further, if Figure 3 As shown, there are two suction ports 13, and the sizes of the two suction ports 13 can be set to be different. The setting of the two suction ports 13 can facilitate batch feeding, and different specifications of aluminum foil cut edges can also be placed in different feed ports 13 for feeding.

[0040] like Figure 3 As shown, preferably, the feed channel 12 is contracted inwardly toward the feed port 8 to form a second cone 14, which is beneficial to reducing air resistance during the feeding process of the aluminum foil trimmings, and facilitates the gathering of the battery aluminum foil trimmings to the feed port 8 for feeding the aluminum foil trimmings.

[0041] In this specific embodiment, the interval between the annular wind knife 3 and the blade wind knife 7 is 5 mm, which has a good cutting effect on the battery aluminum foil and is more conducive to crushing the battery aluminum foil.

[0042] In this specific embodiment, Figure 6 As shown, the wind knife edge 71 is inclined 30 degrees toward one side of the blade 6. The inclined setting of the wind knife edge 71 is more conducive to the blade wind knife 7 cutting the battery aluminum foil. Of course, the inclination angle of the wind knife edge 71 can also be other angles, not limited to this.

[0043] In this specific embodiment, Figure 7 As shown, the annular cutting edge 31 is inclined 30 degrees toward one side of the feed channel 12. The inclined setting of the annular cutting edge 31 is conducive to the blade wind knife 7 cutting the battery aluminum foil. Of course, the inclination angle of the annular cutting edge 31 can also be other angles, not limited to this.

[0044] In this specific embodiment, the wind knife edge 71 is a tooth-shaped structure, which changes the original line distribution into a point distribution, and generates concentrated stress inside the aluminum foil to be cut. Under the action of concentrated stress, the aluminum foil is easier to cut, and the tooth-shaped structure has a better cutting effect. Of course, in other implementations, the wind knife edge 71 can also be a straight shape, a curved shape, a trapezoidal punch edge, etc., but is not limited to this.

[0045] In this specific embodiment, the annular cutting edge 31 is a tooth-shaped structure, which changes the original line distribution into a point distribution, thereby generating concentrated stress inside the aluminum foil to be cut. Under the action of the concentrated stress, the aluminum foil is more easily cut by the tooth-shaped structure cutting edge, and the cutting effect is better. Of course, in other implementations, the wind knife cutting edge 71 can also be a straight shape, a curved shape, a trapezoidal punch cutting edge, etc., but is not limited to this.

[0046] During specific use, the wind knife edge 71 can be an edge of other shapes, which can be used in conjunction with the toothed annular edge 31. The wind knife edge 71 can also be toothed and used in conjunction with annular edges 31 of other shapes. The toothed annular edge 31 can also be used in conjunction with the toothed wind knife edge 71. A variety of usage scenarios can be used, and the edge shape can be adjusted according to different usage scenarios.

[0047] During operation, the suction port 13 of the air guide hood 11 is externally connected to a suction pipe (not shown in the figure), and the discharge port 9 is externally connected to a recovery device. The cut edges of the aluminum foil enter the feed channel 12 through the suction port 13, converge into the feed port 8 of the wind box 2, and are cut off at the feed port 8 by the high-speed rotating blade wind knife 7 and the annular blade 3. After entering different accommodating grooves 17 in batches, they are guided by the first cone 10 and transported to the discharge port 9 by the high-speed rotating blades 6 to be recovered by the external recovery device.

[0048] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
