Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] An existing high-efficiency lithium battery crushing mechanism requires two motors to drive it during actual use. Since two motors need to work at the same time, the total energy consumption is usually twice that of a single motor drive. This means that the energy cost of the dual-motor drive mechanism will be higher when running for a long time. Therefore, the above problem is solved by using a device that can drive the crushing mechanism with a single motor.

[0022] like Figures 1 to 3 It is given that the utility model provides a high-efficiency lithium battery crushing mechanism.

[0023] Specifically, by Figure 1-2 A high-efficiency lithium battery crushing mechanism is provided, comprising an outer box 1, a discharge port 10 and a crushing assembly 2, wherein the discharge port 10 is located inside the outer box 1 and is used to discharge the crushed lithium battery, the crushing assembly 2 is located inside the outer box 1 and crushes the lithium battery, the crushing assembly 2 comprises two fixed rods 201 rotatably connected to the inner wall of the outer box 1, a crushing roller 202 is installed on the outer wall of the fixed rod 201, a servo motor 203 is installed on the inner wall of the outer box 1, a driving end of the servo motor 203 is connected to one end of one of the fixed rods 201, and the two fixed rods 201 are cross-connected. The fork is connected to a belt 204 for transmission, and a connecting rod 205 is rotatably connected to the inner wall of the outer box 1, a first transmission belt 206 is transmitted between one of the fixed rods 201 and the connecting rod 205, a plurality of support rods 207 are rotatably connected to the inner wall of the outer box 1, a second transmission belt 208 is transmitted between the connecting rod 205 and one of the support rods 207, a gear 209 is installed on the outer wall of the support rod 207, and the plurality of gears 209 are meshed and connected, a plurality of blades 210 are integrally formed on the outer wall of the support rod 207, and the fixed rod 201 is located directly below the crushing roller 202.

[0024] In the utility model, the lithium battery to be crushed is poured from the top of the outer box 1 between the two crushing rollers 202, and one of the fixed rods 201 is driven to rotate by the servo motor 203. The rotating fixed rod 201 drives the other fixed rod 201 to rotate through the belt 204, and the rotating fixed rod 201 drives the crushing roller 202 to rotate. The two crushing rollers 202 rotate to perform preliminary crushing on the lithium battery between the two crushing rollers 202. The lithium battery squeezed by the two rotating crushing rollers 202 will become a number of small-volume fragments, and these fragments will fall between the multiple blades 210 below the crushing roller 202;

[0025] One of the rotating fixed rods 201 drives the connecting rod 205 to rotate synchronously through the first transmission belt 206, and the rotating connecting rod 205 drives one of the support rods 207 through the second transmission belt 208. When one of the support rods 207 rotates, it will drive one of the gears 209 to rotate, and then the rotating gear 209 will drive the gear 209 in the middle part and the support rod 207 in the middle part to rotate, and the gear 209 in the middle part will drive another gear 209 and the support rod 207 to rotate together. When multiple support rods 207 rotate, they will drive multiple blades 210 to rotate together, and the lithium battery fragments are crushed by the rotation of multiple blades 210. The overall operation process can be realized by only a single servo motor 203, reducing the energy cost of operating the drive structure of more than one servo motor 203.

[0026] As a specific implementation of the utility model, the utility model provides a high-efficiency lithium battery crushing mechanism.

[0027] Specifically, Figure 1 It is shown that the outer walls of the connecting rod 205 and one of the supporting rods 207 are both installed with a limiting ring 7 , and the limiting ring 7 is located on one side of the second transmission belt 208 and the outer wall of the limiting ring 7 is close to one side of the second transmission belt 208 .

[0028] In the utility model, the limiting ring 7 is used to limit the second transmission belt 208 to prevent the second transmission belt 208 from being offset and affecting the rotation of the support rod 207 when rotating around the connecting rod 205 and the support rod 207. The limiting ring 7 makes the transmission of the second transmission belt 208 more stable and prevents the second transmission belt 208 from rubbing against the inner wall of the outer box 1 when rotating, thereby reducing the wear caused by friction between the second transmission belt 208 and the outer box 1.

[0029] As another specific implementation of the utility model, the utility model provides a high-efficiency lithium battery crushing mechanism.

[0030] Specifically, Figure 1-2It is shown that two partitions 3 are installed on the inner wall of the outer box 1 , the crushing roller 202 and the blade 210 are located between the two partitions 3 , and an arc bottom plate 6 is connected between the two partitions 3 , and the arc bottom plate 6 is located at the bottom of the partition 3 .

[0031] In the utility model, two partitions 3 separate the crushing roller 202 and the blade 210 to prevent the debris generated by the crushing roller 202 and the blade 210 when crushing the lithium battery from splashing onto the gear 209 and the second transmission belt 208, so as to prevent the debris from affecting the transmission of the second transmission belt 208 and the rotation function of the gear 209, and at the same time effectively prevent the problem of debris splashing. The arc bottom plate 6 is used to receive the fragments of the lithium battery to prevent the fragments from scattering into the interior of the outer box 1.

[0032] As another specific implementation of the utility model, the utility model provides a high-efficiency lithium battery crushing mechanism.

[0033] Specifically, Figure 1-3 It is shown that the arc bottom plate 6 is provided with a material guide port 12 , which is located above the material discharge port 10 . The material guide port 12 corresponds to one end of the material discharge port 10 , and two second inclined blocks 11 are installed inside the material guide port 12 .

[0034] In the utility model, when the lithium battery fragments crushed by the blade 210 fall onto the inner wall of the arc-shaped bottom plate 6, the curvature of the arc-shaped bottom plate 6 can be used to make the fragments slide directly into the position of the guide port 12, and the fragments can be discharged from between the arc-shaped bottom plate 6 and the partition 3 through the guide port 12. The guide port 12 is located above the discharge port 10, which is convenient for the lithium battery fragments to fall directly from the guide port 12 into the inside of the discharge port 10, and then the discharge port 10 discharges these fragments into the interior of the outer box 1. The second inclined block 11 has a guiding function, making it easier for the fragments to slide downward from the position of the guide port 12.

[0035] As another specific implementation of the utility model, the utility model provides a high-efficiency lithium battery crushing mechanism.

[0036] Specifically, Figure 1-3 It is given that the inner bottom wall of the outer box 1 is installed with an inclined plate 8, and the inclined plate 8 is located between the material guide port 12 and the material discharge port 10. The inner bottom wall of the outer box 1 is installed with a baffle 9, and the baffle 9 is located between the arc bottom plate 6 and the outer box 1. The material guide port 12 and one end of the material discharge port 10 are both located between the inclined plate 8 and the baffle 9.

[0037] In the utility model, the inclined plate 8 and the baffle plate 9 have the functions of guiding and blocking, which can not only guide the fragments falling from the guide port 12 to the inside of the discharge port 10, but also prevent the fragments from splashing onto the inner bottom wall of the outer box 1 after falling from the guide port 12, thereby avoiding the accumulation of fragments inside the outer box 1.

[0038] As another specific implementation of the utility model, the utility model provides a high-efficiency lithium battery crushing mechanism.

[0039] Specifically, Figure 1-2 It is given that a fixing plate 5 is installed on the inner wall of the outer box 1, the servo motor 203 is installed on the top of the fixing plate 5, the fixing plate 5 is located between the outer box 1 and the partition 3, two first tilting blocks 4 are installed on the inner wall of the outer box 1, the first tilting blocks 4 are located on the top of the partition 3, and the fixing rod 201 and the servo motor 203 are both located below the first tilting blocks 4.

[0040] In the utility model, the servo motor 203 is unstable during operation. The servo motor 203 is fixed by the fixing plate 5, so that the servo motor 203 is more secure during operation. At the same time, the fixing plate 5 and the servo motor 203 are both located below one of the first inclined blocks 4, which can effectively prevent the lithium battery from hitting the servo motor 203 and affecting the operation of the servo motor 203. The first inclined block 4 also has a guiding function, so that the lithium battery can slide directly between the two crushing rollers 202, so that the crushing roller 202 can directly crush the lithium battery.

[0041] Working principle: Pour the lithium battery to be crushed from the top of the outer box 1 between the two crushing rollers 202, and drive one of the fixed rods 201 to rotate through the servo motor 203. The rotating fixed rod 201 drives the other fixed rod 201 to rotate through the belt 204, and the rotating fixed rod 201 drives the crushing roller 202 to rotate. The two crushing rollers 202 rotate to perform preliminary crushing on the lithium battery between the two crushing rollers 202. The lithium battery squeezed by the two rotating crushing rollers 202 will become a number of small fragments, and these fragments will fall between the multiple blades 210 below the crushing roller 202;

[0042] One of the rotating fixed rods 201 drives the connecting rod 205 to rotate synchronously through the first transmission belt 206, and the rotating connecting rod 205 drives one of the support rods 207 through the second transmission belt 208. When one of the support rods 207 rotates, it will drive one of the gears 209 to rotate, and then the rotating gear 209 will drive the gear 209 in the middle part and the support rod 207 in the middle part to rotate, and the gear 209 in the middle part will drive another gear 209 and the support rod 207 to rotate together. When multiple support rods 207 rotate, they will drive multiple blades 210 to rotate together, and the lithium battery fragments are crushed by the rotation of multiple blades 210. The overall operation process can be realized by only a single servo motor 203, reducing the energy cost of operating the drive structure of more than one servo motor 203.
