A raw material recycling device for lithium battery production includes a bottom plate 1, a body 2 is installed on the surface of the bottom plate 1, a baffle 3 is installed inside the body 2, a separation mechanism 4 is arranged inside the body 2, the separation mechanism 4 includes a first motor 41 installed on one side of the body 2, a cam 42 is key-connected to the output shaft of the first motor 41, a connecting rod 43 is rotatably installed on the surface of the cam 42, one end of the connecting rod 43 is rotatably installed with a sieve plate 44, sieve holes 45 are opened on the surface of the sieve plate 44, and a slide bar 46 is installed inside the body 2.

[0021] Two groups of slide bars 46 are installed inside the body 2, and the sieve plate 44 forms a sliding structure with the body 2 through the slide bars 46. When the crushed battery falls on the sieve plate 44, in order to separate the raw material from the shell and facilitate the recycling of the raw material, the first motor 41 can be started. The first motor 41 drives the cam 42 to rotate. While the cam 42 rotates, it pulls the connecting rod 43. While the connecting rod 43 is being pulled, it pulls the sieve plate 44 at one end. The sieve plate 44 slides inside the body 2 through the slide bars 46, and the raw material falls through the sieve holes 45 opened on the surface, and the battery shell remains on the surface. In this way, the raw material and the shell are separated, which facilitates the recycling of the raw material and improves the use effect of the equipment.

[0022] Inside the machine body 2, a crushing mechanism 5 is provided. The crushing mechanism 5 includes a second motor 51 installed on one side of the machine body 2. The output shaft of the second motor 51 is keyway-connected with a first driving gear 52. A second driving gear 53 is meshed on the surface of the first driving gear 52. A crushing roller 54 is connected to the center of the second driving gear 53. Crushing teeth 55 are installed on the surface of the crushing roller 54. Pour the battery to be recycled into the machine body 2, and then start the second motor 51. The second motor 51 drives the first driving gear 52 and the second driving gear 53 to make the crushing roller 54 rotate. The two groups of crushing rollers 54 rotate and contact the battery through the crushing teeth 55 on the surface to crush it, and then it falls for the next operation.

[0023] Both ends of the crushing roller 54 are connected to the machine body 2 through bearings, and two groups of the crushing mechanism 5 are provided inside the machine body 2.

[0024] A pulling mechanism 6 is provided at the bottom of the machine body 2. The pulling mechanism 6 includes a sliding plate 61 installed at the bottom of the machine body 2. A driving motor 62 is installed on the surface of the sliding plate 61. A first parallel gear 63 is installed on the output shaft of the driving motor 62.

A rope 66 is provided on the surface of the winding roller 65. One end of the rope 66 pulls a collection box 67. A placement hole 68 is opened at the bottom of the machine body 2. When the raw materials fall into the collection box 67, then start the driving motor 62 to drive the first parallel gear 63 and the second parallel gear 64 to make the winding roller 65 rotate. The winding roller 65 rotates to wind the rope 66, and the collection box 67 is pulled through the rope 66, and the collection box 67 is pulled out from the placement hole 68, which is convenient for collecting the raw materials.

[0025] The collection box 67 forms a sliding structure with the machine body 2 through the sliding plate 61, and the size of the collection box 67 is adapted to the size of the placement hole 68.

[0026] The working principle of a raw material recycling device for lithium battery production provided by the present utility model is as follows:

[0027] The first step: First, pour the battery to be recycled into the machine body 2, and then start the second motor 51. The second motor 51 drives the first driving gear 52 and the second driving gear 53 to make the crushing roller 54 rotate. The two groups of crushing rollers 54 rotate and contact the battery through the crushing teeth 55 on the surface to crush it, and then it falls for the next operation.

[0028] Step 2: Then the crushed battery falls onto the sieve plate 44. In order to separate the raw material from the outer shell and facilitate the recovery of the raw material, the first motor 41 can be started. The first motor 41 drives the cam 42 to rotate. While the cam 42 rotates, it pulls the connecting rod 43. While the connecting rod 43 is being pulled, it pulls one end of the sieve plate 44. The sieve plate 44 slides in the machine body 2 through the slide bar 46. The raw material falls through the sieve holes 45 opened on the surface, and the battery outer shell remains on the surface. In this way, the raw material and the outer shell are separated, facilitating the recovery of the raw material and improving the use effect of the equipment.

[0029] Step 3: When the raw material falls into the collection box 67, then start the drive motor 62 to drive the first parallel gear 63 and the second parallel gear 64 to rotate the winding roller 65. The winding roller 65 winds the rope 66. The collection box 67 is pulled by the rope 66, and the collection box 67 is pulled out from the placement hole 68. In this way, it is convenient to collect the raw material.

[0030] Compared with the related technology, a raw material recovery device for lithium battery production provided by the present utility model has the following beneficial effects:

[0031] The device is designed with a separation mechanism. When the device is in use, in order to separate the raw material from the outer shell and facilitate the recovery of the raw material, the first motor can be started. The first motor drives the cam to rotate. While the cam rotates, it pulls the connecting rod. While the connecting rod is being pulled, it pulls one end of the sieve plate. The sieve plate slides in the machine body through the slide bar. The raw material falls through the sieve holes opened on the surface, and the battery outer shell remains on the surface. In this way, the raw material and the outer shell are separated, facilitating the recovery of the raw material and improving the use effect of the equipment.

[0032] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
