Description

Technical Field

[0001] This utility model relates to the field of used battery recycling and processing technology, specifically to a lead-acid battery cutting device. Background Technology

[0002] Lead-acid batteries are widely used in automobiles, electric vehicles, and backup power supplies. As they reach the end of their lifespan, a large number of used lead-acid batteries are generated. These used batteries contain lead, sulfuric acid electrolyte, and other substances. Improper disposal not only wastes resources but also causes serious environmental pollution. Therefore, the standardized recycling and disposal of used lead-acid batteries is crucial.

[0003] Currently, the first step in the recycling and processing of waste lead-acid batteries is to cut open the casing to drain the internal sulfuric acid electrolyte, followed by the recycling of internal components such as plates and separators. Existing equipment for cutting waste lead-acid battery casings has several shortcomings: First, the cutting precision is low, easily damaging the internal plates and affecting the quality of subsequent lead resource recycling; second, during cutting, the internal liquid draining rate is slow, and liquid splashing is likely to occur, polluting the equipment and operating environment, and potentially posing safety hazards to operators; third, the equipment has a low degree of automation, requiring significant manual intervention, resulting in low processing efficiency and making it difficult to meet the needs of large-scale waste lead-acid battery recycling and processing; fourth, existing equipment has poor versatility, unable to adapt to the cutting needs of different specifications and models of waste lead-acid batteries, resulting in a narrow range of applications.

[0004] Therefore, developing a cutting device for waste lead-acid batteries with high cutting precision, fast liquid discharge speed, high degree of automation, and strong versatility has become an urgent problem to be solved in the field of waste battery recycling and processing. Summary of the Invention

[0005] This invention addresses the problems of low precision and safety hazards caused by liquid splashing during the cutting process in existing battery casing cutting devices by providing a lead-acid battery cutting device that can cut open the battery, drain the internal electrolyte, and is safer and more reliable in operation, with high cutting precision and efficiency.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A lead-acid battery cutting device is disclosed for cutting lead-acid batteries. One side of the battery has a cover plate with terminals. The cutting device cuts open the cover plate to release the electrolyte from the battery. The device includes a frame with a conveyor belt for transporting the battery. The frame also includes a positioning mechanism, a clamping mechanism, and a cutting mechanism. The positioning mechanism defines the position of the battery on the conveyor belt, the clamping mechanism presses the battery firmly onto the conveyor belt, and the cutting mechanism cuts the surface of the battery. A housing covers the cutting and clamping mechanisms, and a fan is connected to the housing. This device achieves high efficiency, safety, and environmental friendliness in the lead-acid battery cutting process, effectively preventing electrolyte leakage and acid mist emission.

[0007] Furthermore, a pallet is provided on one side of the conveyor belt, the upper surface of which is flush with the conveying surface of the conveyor belt. The positioning mechanism includes a first positioning plate suspended above the conveyor belt and a second positioning plate fixedly mounted on the pallet. The length directions of the first and second positioning plates are parallel to the conveying direction of the conveyor belt. When conveying the battery, the battery cover faces the second positioning plate, and the opposite side of the cover faces the first positioning plate. The first and second positioning plates provide bidirectional positioning for the battery, preventing it from tilting or twisting during the cutting process.

[0008] Furthermore, a hinged door is provided on the front side of the housing, and a battery inlet and a battery outlet are respectively provided on both sides of the housing. A conveyor belt passes between the inlet and the outlet. A pressing mechanism and a cutting mechanism are provided on the inner wall of the housing opposite to the hinged door. The hinged door facilitates operation and maintenance.

[0009] Furthermore, the cutting mechanism includes an upper saw blade and a lower saw blade rotatably mounted on the inner wall of the housing. The upper and lower saw blades are driven by a motor, and their cutting directions are perpendicular to the conveying direction of the conveyor belt. The upper saw blade cuts the upper surface of the battery, and the lower saw blade cuts the lower surface of the battery. The upper and lower saw blades cut synchronously, causing the electrolyte inside the battery to flow out rapidly.

[0010] Furthermore, the clamping mechanism includes at least two sets of clamping rollers rotatably mounted above the conveyor belt. The rims of the clamping rollers are provided with rectangular teeth. The clamping rollers are driven by a motor, and their lower edges press against the upper surface of the battery. During conveying, the battery is continuously clamped and pulled, effectively preventing battery displacement or vibration during cutting and ensuring smooth and precise cutting.

[0011] Furthermore, the clamping mechanism also includes an arc-shaped track, a driven shaft, and a driving shaft. An arc-shaped slider is slidably disposed within the track, and the clamping wheel is rotatably mounted on the arc-shaped slider via the driven shaft. The driving shaft is rotatably disposed on the housing at the center of the arc-shaped track, and the driving shaft and the driven shaft are connected by a transmission mechanism. When the battery passes by, the clamping wheel is driven to rotate and can swing along the arc-shaped track to adapt to the height of the battery. Furthermore, the transmission mechanism is a chain drive, with one end of the driven shaft fixed to the pressure wheel and the other end fixed to a driven sprocket, and a driving sprocket fixed on the driving shaft; a linkage mechanism is also provided between the driven shaft and the driving shaft, with one end of the linkage mechanism rotatably connected to the driven shaft and the other end rotatably connected to the driving shaft. The linkage mechanism is used to support the driven shaft and enhance structural stability.

[0012] Furthermore, the conveyor belt is a chain conveyor belt. This prevents electrolyte from accumulating on the conveying surface and ensures stable support for the battery.

[0013] Furthermore, a belt conveyor is connected to the end of the conveyor belt, and the conveying surface of the belt conveyor is inclined upwards. The belt conveyor lifts and transports the cut and drained batteries to the next workstation.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: This invention offers high cutting precision and improved efficiency: through the coordinated action of the positioning and clamping mechanisms, the battery maintains a stable position and accurate posture during transport and cutting; the design of simultaneous cutting by the upper and lower saw blades ensures a smooth cut and rapid liquid drainage, significantly improving cutting quality and efficiency.

[0015] This utility model is safe and environmentally friendly: by covering the cutting mechanism and the clamping mechanism with a shell, the cutting process is carried out inside the shell, and a fan is connected to the shell, which can effectively collect the acid mist and splashed electrolyte generated during cutting, thus avoiding environmental pollution and health hazards to operators.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-4 As shown, this embodiment provides a lead-acid battery cutting device for cutting open the surface of the lead-acid battery 1 to drain the electrolyte from the battery 1, thereby facilitating the subsequent recycling of battery plates, separators, and other components. It should be noted that in this embodiment, the cutting mechanism 6 only cuts the connection between the battery 1 and the cover plate 11, and does not directly separate the cover plate 11 from the battery 1. In the next step of cutting and draining the electrolyte, the plastic casing and internal materials of the battery 1 are then separated.

[0018] In this embodiment, the battery 1 is a lead-acid battery. A cover plate 11 is provided on one side of the battery 1, and a terminal 12 is provided on the cover plate 11. The cutting position of the lead-acid battery cutting device is the connection point between the battery 1 and the cover plate 11.

[0019] like Figure 1 As shown, the lead-acid battery cutting device includes a frame 2 and a conveyor belt 3, a positioning mechanism 4, a pressing mechanism 5, a cutting mechanism 6, and a housing 7 mounted on the frame 2; a demisting fan 71 is connected to the housing 7; a belt conveyor is connected to the end of the conveyor belt 3, and the conveying surface of the belt conveyor is inclined upwards at a 20° angle. After cutting, the waste lead-acid batteries 1 are directly loaded onto the vehicle. The bottom of the belt conveyor is equipped with tires to facilitate equipment movement and adapt to use in multiple directions.

[0020] The frame 2 is used to support the conveyor belt 3 and the housing 7. The frame 2 is equipped with a conveyor belt 3 for conveying the battery 1. The conveyor belt 3 is a stainless steel chain plate conveyor belt, which avoids the accumulation of electrolyte on the conveying surface and ensures stable support for the battery.

[0021] The positioning mechanism 4 defines the position of the battery 1 on the conveyor belt 3. The positioning mechanism 4 includes a first positioning plate 41 and a second positioning plate 42. Specifically, a support plate 31 is provided on one side of the conveyor belt 3. The support plate 31 is square and intermittently arranged on one side of the conveyor belt 3. The upper surface of the support plate 31 is flush with the conveying surface of the conveyor belt 3 or lower than the conveying surface of the conveyor belt 3. The support plate 31 is made of smooth metal to reduce the friction between the battery 1 and the support plate 31. The conveyor belt 3 transports the battery 1 and drives the battery 1 to slide along the support plate 31. In a specific embodiment, most of the battery body is located on the conveyor belt 3, and only the cover plate is located on the support plate 31, thus enabling the battery 1 to slide relative to the support plate 31.

[0022] The positioning mechanism 4 includes a first positioning plate 41 suspended above the conveyor belt 3 and a second positioning plate 42 fixedly mounted on the pallet 31. The first positioning plate 41 and the second positioning plate 42 are elongated strips. Figure 3 As shown, the first positioning plate 41 is fixed to the housing 7 by a connecting rod, and the second positioning plate 42 is welded to the edge of the pallet 31. The length direction of the first positioning plate 41 and the second positioning plate 42 is parallel to the conveying direction of the conveyor belt 3. The distance between the first positioning plate 41 and the second positioning plate 42 is slightly larger than the width of the battery 1. When conveying the battery 1, the cover plate 11 of the battery 1 with terminals 12 faces the second positioning plate 42, and the terminals 12 are located above the second positioning plate 42. The other side opposite to the cover plate 11 faces the first positioning plate 41. The first positioning plate 41 and the second positioning plate 42 restrict the position of the battery 1 on the conveyor belt 3 and prevent the battery 1 from twisting during transportation. To show the pallet 31, the second positioning plate 42 is not fully shown in the length direction in the figure.

[0023] The clamping mechanism 5 clamps the battery 1 onto the conveyor belt 3, such as Figure 4 As shown, the clamping mechanism 5 includes a clamping wheel 51, an arc-shaped slider 54, and a driven shaft 52. The clamping wheel 51 is rotatably mounted on the arc-shaped slider 54 via the driven shaft 52, and is matched with, as shown in the figure. Figure 3As shown, an arc-shaped track is provided on the inner wall of the housing 7. The arc-shaped slider 54 is slidably disposed in the arc-shaped track. The clamping wheel 51 is driven to rotate by a motor. When the battery 1 is transported to the clamping wheel 51, the clamping wheel 51 rotates around the axis of the driven shaft 52 under the drive of the motor. The lower edge of the clamping wheel 51 is pressed against the upper surface of the battery 1. The rim of the clamping wheel 51 is provided with rectangular teeth, which assists in transport through friction. At the same time, the height change of the battery 1 is transmitted to the arc-shaped slider 54 through the clamping wheel 51, forcing the arc-shaped slider 54 to slide along the arc-shaped track, thereby driving the entire driven shaft 52 and the clamping wheel 51 to revolve around the center of the arc-shaped track, realizing the lifting and lowering of the clamping wheel 51 to dynamically adapt to the shape of the battery 1 and maintain stable clamping.

[0024] The lower edge of the clamping roller 51 moves in the same direction as the conveying direction of the conveyor belt 3, and both operate at the same speed to achieve the effect of clamping and stabilizing the feeding. A groove is provided inside the arc-shaped track, and a protrusion matching the groove is provided outside the arc-shaped slider 54 to achieve sliding engagement between the arc-shaped slider 54 and the arc-shaped track, preventing the arc-shaped slider 54 from slipping off.

[0025] In one possible implementation, the motor drives the clamping wheel 51 to rotate via chain drive. The clamping mechanism 5 also includes a drive shaft 53, which is rotatably mounted on the housing 7 at the center of the arc-shaped track and rotatably connected to the housing 7 via bearings. (See [link]) Figure 3 The housing 7 includes a front side and a rear side. The pressure roller 51, conveyor belt 3, and cutting saw blade are located on the front side of the housing, while the drive shaft 53 and motor are located on the rear side of the housing. Figure 3 The middle section is not shown due to obstruction. The rear end of the driven shaft 52 extends from the front side of the housing to the rear side of the housing through the housing wall, and the driving shaft 53 is rotatably disposed on the rear side of the housing.

[0026] The drive shaft 53 and the driven shaft 52 are connected by a transmission mechanism. The transmission mechanism is a chain drive. One end of the driven shaft 52 is fixed to the pressure wheel 51, and the other end is fixed to a driven sprocket 55. A drive sprocket 56 is fixed to the drive shaft 53. To ensure structural stability, a linkage mechanism 57 is also provided between the driven shaft 52 and the drive shaft 53. One end of the linkage mechanism 57 is rotatably connected to the driven shaft 52, and the other end is rotatably connected to the drive shaft 53. The drive shaft 53 is rotatably mounted on the rear side of the housing by a bracket. The specific connection method is as follows: Figure 4 As shown.

[0027] To ensure a proper clamping effect, the clamping mechanism 5 includes at least two sets of clamping rollers 51 rotatably mounted above the conveyor belt 3. At least one set of clamping rollers 51 is positioned upstream of the cutting mechanism 6, and at least one set of clamping rollers 51 is positioned downstream of the cutting mechanism 6, enabling the cutting mechanism 6 to achieve stable clamping during the cutting process. Figure 3 The image shows three sets of clamping rollers.

[0028] The cutting mechanism 6 cuts the surface of the battery 1, such as... Figure 3 As shown, the cutting mechanism 6 includes an upper saw blade 61 and a lower saw blade 62 rotatably mounted on the inner wall of the housing 7. The upper saw blade 61 and the lower saw blade 62 are driven by separate motors located on the rear side of the housing. Both the upper saw blade 61 and the lower saw blade 62 are identical finished disc-type alloy saw blades, differing only in their position. The upper saw blade 61 is suspended above the conveyor belt 3, and the lower saw blade 62 is positioned between the conveyor belt 3 and the second positioning plate 42, with its upper edge higher than the conveying surface of the conveyor belt 3. The cutting direction of the upper saw blade 61 and the lower saw blade 62 is perpendicular to the conveying direction of the conveyor belt 3. The upper saw blade 61 cuts the upper surface of the battery 1, and the lower saw blade 62 cuts the lower surface of the battery 1.

[0029] The cutting mechanism 6 and the pressing mechanism 5 are covered by a housing 7. A movable door is hinged to the front of the housing 7. A battery inlet and a battery outlet are respectively provided on both sides of the housing 7. A conveyor belt 3 passes between the inlet and the outlet. The pressing mechanism 5 and the cutting mechanism 6 are provided on the inner wall of the housing 7 opposite to the movable door. A collection tank for receiving electrolyte is provided at the bottom of the housing 7.

[0030] In use, the battery 1 is placed on the conveyor belt 3 with the cover plate 11 facing the second positioning plate 42. The first positioning plate 41 and the second positioning plate 42 restrict the position of the battery 1 on the conveyor belt 3 to prevent the battery 1 from twisting and causing the cut to tilt. When the battery 1 moves to the upstream pressure roller 51, the pressure roller 51 and the conveyor belt 3 work together to stably transport it to the cutting station. The high-speed rotating upper saw blade 61 and lower saw blade 62 cut the upper and lower surfaces of the battery 1 to complete the kerf operation so that the electrolyte can be discharged.

[0031] During this process, the adaptive lifting function of the clamping mechanism 5 ensures the stability of the cutting process. After cutting and draining, the battery 1 is assisted by the downstream clamping roller 51 to be sent out of the housing 7, and finally lifted and transferred to the next separation station by the inclined belt conveyor. Throughout the process, the demisting fan 71 works continuously to exhaust harmful gases.

[0032] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
