Description

Technical Field

[0001] The present invention relates to the field of battery shell material production, in particular to a granulation device for battery shell material. Background Art

[0002] A storage battery is a device that converts chemical energy directly into electrical energy. It is designed to be rechargeable and is recharged through a reversible chemical reaction. It typically refers to a lead-acid battery, a type of secondary battery. Its working principle is that during charging, it uses external electrical energy to regenerate the internal active substances, storing the electrical energy as chemical energy. When it needs to be discharged, the chemical energy is converted back into electrical energy for output. An example of this is the battery commonly used in mobile phones.

[0003] The battery casing, which holds the electrolyte and plate assembly, should be acid-, heat-, and shock-resistant. It's typically made of hard rubber or polypropylene plastic and is a monolithic structure with raised ribs on the bottom to support the plate assembly. Polypropylene plastic casings are acid-, heat-, and shock-resistant, as well as strong. They have thin walls (typically 3.5mm, compared to 10mm for hard rubber), are lightweight, aesthetically pleasing, and transparent.

[0004] Currently, to facilitate the use of battery case materials, the produced battery case materials are generally first made into granules for easy transportation and use. The specific steps are to first heat the battery case material, then extrude the heated battery case material into strips, then place the strips into water to cool them, and then cut the cooled battery case material into granules. However, most existing extrusion devices extrude the battery case material from the side, and the strips of battery case material have some distance to go before entering the water pool. The strips of battery case material are easily entangled, which leads to uneven size when subsequently cut. Summary of the Invention

[0005] In order to overcome the disadvantage that strip-shaped battery shell materials in existing extrusion devices are easily entangled before entering the water pool, affecting subsequent cutting, the present invention provides a granulation device for battery shell materials that can prevent strip-shaped battery shell materials from entanglement and ensure uniform cutting volume.

The collecting box is fixedly connected to the base, the collecting frame is slidably connected to the collecting box, the cutting box is fixedly connected to the collecting box, the cutting box is communicated with the collecting box, the observation window is arranged on the left and right sides of the cutting box, the extrusion box is connected and communicated with the cutting box, the feeding pipe is connected to the left and right sides of the extrusion box, the feeding pipe is connected and communicated with the extrusion box, the cylinder is installed on the extrusion box, the telescopic rod of the cylinder is connected to the extrusion plate, the extrusion plate is located in the extrusion box, and the device also includes a cooling mechanism and a cutting mechanism.

[0008] Preferably, the cutting mechanism includes a mounting frame, a motor, a mounting block, a connecting rod, a push block, a slide rail, a fixed plate, a cutting block, a connecting plate and a return spring. The mounting frame is fixed to the front side of the collection box, and motors are installed at both ends of the mounting frame. The mounting block is fixed to the left and right sides of the collection box. The connecting rod is rotatably connected to the mounting block. The output shaft of the motor is connected to the front end of the connecting rod through a coupling. The push block is fixed to the middle of the connecting rod. A slide rail is fixed to the rear of the collection box. The fixed plate is fixed to the front and rear walls of the collection box. The cutting block is slidably connected to the slide rail and the fixed plate. A return spring is connected between the cutting block and the fixed plate. The connecting plate is fixed to the outside of the cutting block.

[0009] Preferably, a cleaning mechanism is also included, which includes gears, scrapers and racks. Gears are fixed to the front and rear ends of the cooling tube. The scrapers are symmetrically fixed to the inner wall of the cutting box. The racks are fixed to the front and rear walls of the cutting box, and the gears and racks are meshed.

[0010] Preferably, a sorting mechanism is also included, which includes a rotating shaft, a dispersion roller and a pulley group. The two rotating shafts are rotatably connected to the collection box, the dispersion roller is fixed to the rotating shaft, and the rotating shaft is driven by the pulley group and the connecting rod.

[0013] By adopting the above scheme, the beneficial effects achieved by the present invention are as follows:

[0014] 1. The present invention is provided with a cooling pipe, and cold water is injected into the cooling pipe through the external water pipe of the connecting pipe. Then the connecting pipe and the cooling pipe are moved up and down to cool the strip battery shell material. After cooling, the strip battery shell material is directly cut into blocks, so that the strip battery shell material is not easy to be entangled.

[0015] 2. In the present invention, the motor drives the connecting rod and the push block to rotate, so that the push block pushes the connecting plate and the cutting block to move inward, so that the cutting block intermittently cuts the cooled strip-shaped battery casing material, which can prevent the strip-shaped battery casing material from being entangled and help maintain consistent cutting length.

[0016] 3. In the present invention, when the sliding frame moves upward, it drives the cooling pipe and the gear to move upward. The gear and the rack are in contact and meshing, causing the gear and the cooling pipe to rotate, so that impurities on the cooling pipe are scraped off by the scraper, thereby removing impurities on the cooling pipe and preventing the presence of impurities on the cooling pipe from affecting the cooling of the battery housing.

[0017] 4. The rotating shaft of the present invention rotates together with the connecting rod through the pulley set, and the dispersion roller rotates along with the rotating shaft. The dispersion roller separates the cooled and divided battery shells to prevent the battery shells from sticking together. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and examples.

[0033] Example 1

[0034] A granulating device for battery shell material, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a base 1, a collecting box 2, a collecting frame 3, a cutting box 4, an observation window 5, an extrusion box 6, a feeding pipe 7, a cylinder 8 and an extrusion plate 9. The collecting box 2 is welded on the base 1, the collecting frame 3 is slidingly connected to the collecting box 2, the cutting box 4 is fixed to the collecting box 2, the cutting box 4 is communicated with the collecting box 2, the observation window 5 is arranged on the left and right sides of the cutting box 4, the extrusion box 6 is connected and communicated with the cutting box 4, the feeding pipe 7 is connected on the left and right sides of the extrusion box 6, the feeding pipe 7 is connected and communicated with the extrusion box 6, the cylinder 8 is installed on the extrusion box 6, the telescopic rod of the cylinder 8 is connected to the extrusion plate 9, the extrusion plate 9 is located in the extrusion box 6, and also includes a cooling mechanism 10 and a cutting mechanism 11.

[0035] like Figure 4 and Figure 5As shown, the cooling mechanism 10 includes a fixed rod 1001, a sliding frame 1002, a connecting pipe 1003 and a cooling pipe 1004. The fixed rod 1001 is fixedly connected to the collecting box 2, the sliding frame 1002 is slidingly connected to the fixed rod 1001, the connecting pipe 1003 is fixedly connected to the sliding frame 1002, the connecting pipe 1003 is slidingly connected to the cutting box 4, and the cooling pipe 1004 is rotatably connected to the connecting pipe 1003.

[0036] like Figure 6 and Figure 7 As shown, the cutting mechanism 11 includes a mounting frame 1101, a motor 1102, a mounting block 1103, a connecting rod 1104, a push block 1105, a slide rail 1106, a fixing plate 1107, a cutting block 1108, a connecting plate 1109 and a return spring 1110. The mounting frame 1101 is connected to the front side of the collection box 2 by bolts, and motors 1102 are installed at both ends of the mounting frame 1101. The mounting block 1103 is connected to the left and right sides of the collection box 2 by bolts. The connecting rod 1104 is connected to the mounting block 1103 for rotation. Then, the output shaft of the motor 1102 is connected to the front end of the connecting rod 1104 through a coupling, the push block 1105 is fixedly connected to the middle part of the connecting rod 1104, and the rear part of the collection box 2 is connected to a slide rail 1106 by bolts. The fixed plate 1107 is fixed to the front wall and the rear wall of the collection box 2. The cutting block 1108 is slidably connected to the slide rail 1106 and the fixed plate 1107. A reset spring 1110 is connected between the cutting block 1108 and the fixed plate 1107, and the connecting plate 1109 is connected to the outside of the cutting block 1108 by bolts.

[0037] First, the staff first injects the heated battery shell material into the extrusion box 6 from the feeding pipe 7, starts the cylinder 8, and the telescopic rod of the cylinder 8 drives the extrusion plate 9 downward to extrude the battery shell material. The battery shell extruded into a strip comes out from the bottom of the extrusion box 6, and then the connecting pipe 1003 is connected to the water pipe so that water is injected into the cooling pipe 1004. The cooling pipe 1004 cools the strip of battery shell material. The staff can drive the cooling pipe 1004 up and down by moving the sliding frame 1002 up and down, which helps to enhance the cooling effect. When the pushing block 1105 is separated from the cutting block 1108, the cutting block 1108 will automatically move to both sides and reset under the action of the reset spring 1110, and the cut battery shell particles will fall into the collection box 3 in the collection box 2. After it is full, the collection box 3 will be pulled out and collected.

[0038] Example 2

[0039] On the basis of Example 1, Figure 8 and Figure 9 As shown, a cleaning mechanism 12 is also included, and the cleaning mechanism 12 includes a gear 1201, a scraper 1202 and a rack 1203. The front and rear ends of the cooling tube 1004 are fixed with gears 1201, the scraper 1202 is fixed symmetrically to the inner wall of the cutting box 4, and the rack 1203 is connected to the front wall and the rear wall of the cutting box 4 by bolts, and the gear 1201 and the rack 1203 are engaged.

[0040] When the sliding frame 1002 moves up and down, it will drive the cooling pipe 1004 and the gear 1201 to move up and down. When the gear 1201 moves up and down, it engages with the rack 1203, so that the gear 1201 rotates with the cooling pipe 1004. The cooling pipe 1004 rotates and contacts the scraper 1202. The scraper 1202 cleans the impurities on the surface of the cooling pipe 1004 to prevent the surface of the cooling pipe 1004 from being contaminated with impurities and affecting the cooling effect.

[0041] like Figure 10 As shown, it also includes a sorting mechanism 13, which includes a rotating shaft 1301, a dispersion roller 1302 and a pulley group 1303. The two rotating shafts 1301 are rotatably connected to the collecting box 2, and the dispersion roller 1302 is fixed on the rotating shaft 1301. The rotating shaft 1301 is driven by the pulley group 1303 and the connecting rod 1104.

[0042] When the cut battery shells fall down from the cutting box 4, the rotating shaft 1301 and the dispersion roller 1302 rotate together with the connecting rod 1104 under the action of the pulley group 1303. The dispersion roller 1302 rotates to separate the cooled and divided battery shell particles to prevent the battery shell particles from sticking together.

[0043] like Figure 11 As shown, it also includes a moving mechanism 14, which includes a push plate 1401, a fixed block 1402 and a slider 1403. The push plate 1401 is fixed to the connecting rod 1104, the fixed block 1402 is fixed to the outer walls of the collection box 2 and the cutting box 4, the slider 1403 is fixed to the sliding frame 1002, and the slider 1403 is slidably connected to the fixed block 1402.

[0044] When the motor 1102 drives the connecting rod 1104 to rotate, the push plate 1401 rotates along with the connecting rod 1104, and the push plate 1401 continuously pushes the slider 1403 to move upward. The upward movement of the slider 1403 causes the sliding frame 1002 to drive the cooling pipe 1004 to move upward, and then the sliding frame 1002 will move downward under the action of gravity.

[0045] like Figure 12 and Figure 13As shown, a screening mechanism 15 is also included. The screening mechanism 15 includes a fixing frame 1501 and a screening plate 1502. The fixing frame 1501 is connected to the inner wall of the collecting box 2 by bolts, and the screening plate 1502 is connected to the fixing frame 1501 by bolts.

[0046] The cut and cooled battery shell particles fall onto the screening plate 1502 , which screens the relatively fine powder or battery shells into the collecting frame 3 to ensure that the battery shell particles have a uniform volume.

[0047] The above-described embodiments merely represent preferred embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications, improvements, and substitutions without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
