Description

Technical Field

[0001] The invention relates to the technical field of waste recycling, and in particular to a device for recycling plastic edge materials of a battery cover of a new energy electric vehicle. Background Art

[0002] The battery cover of new energy electric vehicles is usually obtained through a stretching process. After stretching, irregular edges will be left at the mouth of the battery cover, which usually need to be sheared and trimmed. The sheared edges have recycling value. The existing battery cover edge cutting and recycling devices can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] Patent document CN114453494A, published on May 10, 2022, discloses a trimming system and trimming process for battery shells. Its technical solution includes: a frame, a first trimming device, a second trimming device and two sets of trimming vertical pressing devices. The first trimming device includes a first movable knife, a first fixed knife, a first lifting assembly and a first driving assembly. The first movable knife is provided with a first limit through cavity, and the first movable knife cooperates with the first fixed knife to form a shear cut; the second trimming device includes a second movable knife, a second fixed knife and a second driving assembly, and the second movable knife is perpendicular to the moving direction of the first movable knife; the trimming vertical pressing device includes a pressure assembly and a vertical driving mechanism, and the pressure assembly includes a pressure substrate, a pressure member and an elastic recovery member; the sliding direction of the pressure member above the first trimming device is parallel to the moving direction of the first movable knife, and the sliding direction of the pressure member above the second trimming device is parallel to the moving direction of the second movable knife. Its beneficial effect is that it can maintain the good molding quality of the final battery shell.

[0004] The battery covers on the market are usually in the shape of rectangular shells, which results in the edge material produced by the previous stretching process making the overall plane size of the battery cover larger. In the existing actual shearing step, the cutter usually has to be lowered to the actual size of the battery cover for shearing. As a result, there is a possibility of interference between the cutter and the battery cover to be processed during the shearing step. Therefore, a new energy electric vehicle battery cover plastic edge material recycling device is urgently needed to solve the above problem. Summary of the invention

In actual use of the present technical solution, the battery cover to be processed is lowered onto the bracket 4 for positioning, and then the first drive assembly first drives the first cutter 5, so that the first cutter 5 first tilts down and approaches the bracket 4 and then independently descends for cutting, and then the second drive assembly drives the second cutter 6, so that the second cutter 6 first independently moves close to the bracket 4, and at the same time the linkage assembly links the first cutter 5 away from the bracket 4 to avoid the subsequent descending range of the second cutter 6, so that the second cutter 6 can independently descend for cutting without interference, and the above process not only ensures that the battery cover edge material is fully cut, but also coordinates the cutting movements of the two cutters.

[0040] Compared with the prior art, an embodiment of the present invention proposes a method of setting a first drive component and a second drive component, so that the first cutter 5 and the second cutter 6 can first approach the bracket 4 and then descend to cut the battery cover edge material, thereby avoiding interference between the first cutter 5 and the second cutter 6 and the process of lowering the battery cover to be processed onto the bracket 4 before the cutting action; and by setting a linkage component, after the first cutter 5 descends for cutting, when the second cutter 6 independently approaches the bracket 4, the first cutter 5 is linked to move away from the bracket 4 to avoid the subsequent descending range of the second cutter 6, and then the second cutter 6 continues to descend for cutting, thereby ensuring that the battery cover edge material is fully cut and coordinating the cutting movements of the two cutters.

Specifically, the first driving assembly includes a plurality of groups of first supporting frames 9 and structures thereon, and they are evenly arranged along the length direction of the first flat plate 7, and they synchronously apply force to the first cutter 5 to ensure steady and smooth cutting; the opening direction of the first set 11 is perpendicular to its relative On the side of the bracket 4 near the first sliding groove 14, the first telescopic member 12 is movably extended and retracted in the first kit 11, which drives the first cutter 5 to approach or move away from the bracket 4; the first sliding rod 13 is fixedly connected to the first telescopic member 12, and the first sliding rod 13 also movably passes through the side wall of the first kit 11; the first sliding groove 14 includes an upper inclined section and a lower vertical section, and the upper end of the inclined section of the first sliding groove 14 is arranged away from the bracket 4. When the first sliding rod 13 slides downward in the inclined section of the first sliding groove 14, the first telescopic member 12 is linked to extend outside the first kit 11 to drive the first cutter 5 to approach the bracket 4, thereby completing the preparation process for cutting close to the bracket 4; when the first sliding rod 13 slides downward in the vertical section of the first sliding groove 14, the first cutter 5 is linked to descend independently to cut the battery cover edge material.

[0043] As a preferred technical solution of this embodiment, the second driving component includes a second support frame 15 fixedly arranged on the second flat plate 8, a second hydraulic cylinder 16 is fixedly installed on the second support frame 15, the output end of the second hydraulic cylinder 16 faces downward and is connected to a linkage frame 17, a second set 18 which can be elastically lifted and lowered in the second support frame 15 is arranged on the inner side of the linkage frame 17, one end of the second set 18 faces the bracket 4 and is telescopically connected to a second telescopic member 19, the second telescopic member 19 is fixedly connected to the second cutter 6, a second sliding rod 20 is penetrated by the side wall of the second telescopic member 19, and a second sliding groove 21 matching the second sliding rod 20 is arranged on the linkage frame 17. Specifically, the second driving component includes It contains multiple sets of second support frames 15 and structures thereon, and is evenly arranged along the length direction of the second flat plate 8, which synchronously applies force to the second cutter 6 to ensure stable and smooth cutting; the linkage frame 17 is sleeved on the outside of the second set 18, and the inner height is greater than the upper and lower height dimensions of the second set 18; the opening direction of the second set 18 is perpendicular to the side of the bracket 4 adjacent to it, and the movable extension and retraction of the second telescopic member 19 in the second set 18 drives the second cutter 6 to approach or move away from the bracket 4; the elastic lifting function of the second set 18 keeps it in the highest position without being subjected to external force; the second sliding rod 20 is fixedly connected to the second telescopic member 19, and the second sliding groove 21 is inclined, and the upper end is arranged closer to the bracket 4. In actual use of the present technical solution, when the output end of the second hydraulic cylinder 16 extends downward, the linkage frame 17 is pushed down. At this time, the second set 18 is first kept at the highest position under the elastic lifting function, so that the second sliding groove 21 on the linkage frame 17 and the second sliding rod 20 are squeezed and slid, so that the second sliding rod 20 moves toward the upper end of the second sliding groove 21, that is, the second sliding rod 20 links the second telescopic member 19 to extend toward the bracket 4, that is, drives the second cutter 6 to maintain a height and approach the bracket 4; when the second sliding rod 2 After the second hydraulic cylinder 16 moves relatively to the uppermost end of the second sliding groove 21, the linkage frame 17 which is continuously subjected to the downward force can directly push the second sliding rod 20 downward with the help of the second sliding groove 21, and then starts to drive the second telescopic member 19 to descend, and the second set 18 is also subjected to the force to resist the elastic force from descending. At this time, the second cutter 6 is kept close to the side wall of the battery cover on the bracket 4 and descends to realize the cutting of the edge material; on the contrary, when the output end of the second hydraulic cylinder 16 contracts, the second cutter 6 first rises, and after rising to the highest position, it moves away from the bracket 4 and resets.

[0044] As a preferred technical solution of this embodiment, a lifting bin 22 is provided on the inner side of the second support frame 15, and a first elastic member 23 is provided in the lifting bin 22. A lifting block 24 movably connected to the lifting bin 22 is provided on the upper end of the first elastic member 23, and the lifting block 24 is fixedly connected to the second kit 18. Specifically, the lifting and lowering of the lifting block 24 in the lifting bin 22 corresponds to the lifting and lowering stroke of the second cutter 6, and the first elastic member 23 hinders the descent of the second kit 18, so that the second kit 18 is maintained at the highest position without being affected by external forces.

[0045] As the preferred technical scheme of this embodiment, the linkage assembly includes a linkage shaft 25 rotatably arranged on the frame 1, and the rotation of the linkage shaft 25 is linked with the lifting and lowering of the linkage frame 17. A circular plate 26 is rotatably arranged on the inner bottom surface of the first support frame 9, and the circular plate 26 is transmission-connected to the linkage shaft 25. An eccentric rod 27 is arranged on the upper end of the circular plate 26, and a push plate 28 that movably extends out of the bottom surface of the first set 11 is arranged on the lower end of the first telescopic member 12. After the first cutter 5 performs independent descending cutting, the push plate 28 is arranged close to the side of the eccentric rod 27 away from the bracket 4. Specifically, a linkage rod 29 that slides through the second support frame 15 is fixedly arranged on the linkage frame 17, and a rack 30 is fixedly arranged on the linkage rod 29. A gear 31 that meshes with the rack 30 is arranged at the end of the linkage shaft 25; the linkage rod 29 connects the linkage frames 17 in each group of second support frames 15 to each other. When the linkage frame 17 is lifted or lowered, the rack 30 is lifted or lowered by the linkage rod 29, and the rack 30 is meshed with the gear 31 to drive the linkage shaft 25 to rotate; the linkage shaft 25 is arranged on the lower side of the first plate 7, and its axial direction is parallel to the length direction of the first plate 7; a first bevel gear is coaxially fixedly connected to the linkage shaft 25, and a second bevel gear meshing with the first bevel gear is coaxially connected to the lower end of the circular plate 26 through a transmission shaft; during the entire stroke of the linkage frame 17 descending, the linkage circular plate 26 rotates half a circle; when the linkage frame 17 is at the highest position of the lifting stroke, the eccentric rod 27 on the corresponding circular plate 26 is at the position closest to the bracket 4; the push plate 28 is arranged parallel to the side of the bracket 4 close to it, and the length of the push plate 28 is not less than the rotation diameter of the eccentric rod 27, thereby ensuring that the mutual pushing effect between the eccentric rod 27 and the push plate 28 is realized.

[0046] As a preferred technical solution of this embodiment, a retraction groove 32 is provided at the lower end of the first sliding groove 14, and a stop block 34 is connected to the retraction groove 32 through a second elastic member 33. Specifically, the retraction groove 32 is connected to the lower end of the vertical section of the first sliding groove 14, and the retraction groove 32 is horizontally arranged and extends in the direction away from the bracket 4; the second elastic member 33 keeps pushing the stop block 34 close to the bracket 4, that is, blocking the connection position between the first sliding groove 14 and the retraction groove 32. In actual use of the present technical solution, when the first cutter 5 completes the cutting action, the first sliding rod 13 is at the lower end of the vertical section of the first sliding groove 14, the first telescopic member 12 is stretched to the maximum toward the first set 11, and the first telescopic member 12 descends to make the lower push plate 28 close to the side of the eccentric rod 27 away from the bracket 4, and then the driving assembly starts to drive the second cutter 6 to move, the linkage frame 17 descends, and the second cutter 6 first moves horizontally toward the bracket 4, and at the same time, the linkage frame 17 drives the rack 30 to descend through the linkage rod 29 to drive the gear 31 to rotate the linkage shaft 25, and the linkage shaft 25 then drives the circular plate 26 to rotate, and the circular plate 26 drives the eccentric rod 27 to rotate to push the push plate 28 that is in contact with the eccentric rod 27, and the push plate 28 drives the first telescopic member 12 to retract into the first set 11, that is, the first telescopic member 12 drives the first sliding rod 13 to move into the retracting groove 32 to push the stopper 34, and compresses the second elastic member 33 and stores elastic potential energy; when the second cutter 6 is close to the side wall of the battery cover on the bracket 4, the linkage frame 17 starts to drive the second cutter 6 to descend. At this time, the retraction distance of the first cutter 5 is sufficient to avoid the descending range of the second cutter 6, but as the linkage frame 17 drives the second cutter 6 to descend, the circular plate 26 does not rotate half a circle but continues to rotate. On the contrary, when the second cutter 6 rises again after cutting, the first cutter 5 approaches the bracket 4, but when the second cutter 6 has not risen to the highest position, the process of the first cutter 5 approaching the bracket 4 does not interfere with the second cutter 6. When the second cutter 6 rises to the highest position and then moves away from the bracket 4 to reset, the first cutter 5 also gradually approaches the battery cover on the bracket 4.

[0047] In another embodiment of the present invention, a loading plate 35 is provided on the side of the bracket 4 facing the first flat plate 7, a support block 36 is provided on one end of the loading plate 35 close to the conveying end direction of the conveyor belt 2, a pillar 37 is provided at the end of the support block 36, and an arc ramp 38 with the pillar 37 as the center is provided below the other end of the loading plate 35. Specifically, under the condition that the conveying direction of the conveyor belt 2 is determined, when the battery shell is cut through the above process, its long side can fall directly in a direction parallel to the width of the conveyor belt 2 after cutting, and its short side can fall in a direction perpendicular to the width of the conveyor belt 2 after cutting. When the edge materials in both directions subsequently enter the receiving tray 3, they are relatively messy and cross-supported, so that the subsequent materials received by the receiving tray 3 are easy to run out, and the capacity of the receiving tray 3 cannot be fully utilized. The arrangement of the material-laying plate 35 ensures that the edge material cut off by the first cutter 5 will not fall immediately but stay on the material-laying plate 35; one end of the arc-shaped ramp 38 is opposite to the support block 36 in the length direction of the material-laying plate 35 and has the highest height, and the other end is arranged close to the center direction of the corresponding conveyor belt 2, and the curvature of the arc-shaped ramp 38 is preferably 45°~90°; the arc-shaped ramp 38 is fixedly arranged relative to the frame 1; in actual use of this technical solution, the edge material cut off by the first cutter 5 first lies flat on the material-laying plate 35, and then the second cutter 6 performs a cutting movement. When the first cutter 5 is retracted, the first cutter 5 drives the edge material cut off by it to move close to the support block 36. When the long strip of edge material approaches the support block 36, one end of it is supported on the support block 36. The first cutter 5 then moves back and forth along the curved ramp 38, and the other end of the edge material falls on the support block 36, while the other end sinks to the highest position of the curved ramp 38, and one end of the edge material supported on the support block 36 automatically tilts up and abuts against the support column 37. Then, as the first cutter 5 continues to retract, the first cutter 5 only pushes the tilted end of the edge material, so that the edge material rotates around the support column 37, and the end of the edge material resting on the curved ramp 38 slides along the curved ramp 38, thereby changing the direction of the edge material. Finally, when the edge material rotates until the end resting on the curved ramp 38 is separated from the curved ramp 38, the edge material is close to being parallel to the width direction of the conveyor belt 2, and slides down onto the conveyor belt 2, thereby making the edge material falling on the conveyor belt 2 neat, convenient for subsequent collection by the receiving tray 3, and making full use of the space.

[0048] As a preferred technical solution of this embodiment, a side plate 39 is provided on the side of the bracket 4 facing the second flat plate 8, and the side plate 39 and the second flat plate 8 are spaced apart. Specifically, the side plate 39 and the second flat plate 8 are spaced apart so that the edge material cut off by the second cutter 6 can fall directly from the gap onto the conveyor belt 2, and the edge material remains parallel to the width direction of the conveyor belt 2.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
