Description

Technical Field

[0001] This utility model relates to the field of storage battery processing technology, and more specifically, to an automatic plastic casing wrapping device for storage batteries. Background Technology

[0002] A storage battery is a device that directly converts chemical energy into electrical energy. It is designed to be rechargeable, and recharging is achieved through a reversible chemical reaction. It usually refers to lead-acid batteries. After the storage battery is manufactured, a thin film needs to be wrapped around the surface of the battery's plastic casing to prevent scratches during transportation. Nowadays, automatic wrapping devices are often used to complete the wrapping of the battery's plastic casing. In practice, it has the advantages of simple operation, stable structure and good wrapping effect.

[0003] Existing automatic film wrapping devices have cutters exposed to the air. If the cutter is accidentally touched by an operator or an object, it can cause scratches. Furthermore, the cut film cannot be held in place, requiring the operator to locate the cut end of the film before each wrapping operation. Additionally, there is only one film roll structure. Once the film on this roll is used up, the wrapping operation must be stopped before the roll structure can be replaced, which affects work efficiency. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides an automatic plastic casing wrapping device for storage batteries, which has the following advantages:

[0015] (1) This utility model is equipped with a cutting blade and a protective tube. When using the automatic wrapping device for the plastic casing of the storage battery, the plastic casing of the storage battery is first placed on the rotating table, and then the film wound by a set of unwinding rollers is pulled so that one end of the film is attached to the side wall of the plastic casing of the storage battery through two sets of guide rollers. Then, the control panel is used to make the geared motor and the electric heater work. The output end of the geared motor can make the plastic casing of the storage battery rotate through the rotating table. At this time, the film can be wrapped around the side wall of the plastic casing of the storage battery. During this process, the electric heater can heat up the heat-shrink film so that the film is stably wrapped around the side wall of the plastic casing of the storage battery. Then, the control panel is used to extend the two sets of second electric telescopic rods. The opposing ends of the two sets of protective square tubes contact the film first. Afterwards, the two sets of cutting blades continue to move towards each other. During this process, the four sets of mounting plates and the two sets of protective square tubes can compress the eight sets of telescopic springs. When the two sets of cutting blades cut the film, the two sets of second electric telescopic rods are shortened using the control panel. At this time, the eight sets of telescopic springs, under their own elastic force, can continue to push the two sets of protective square tubes to hold one end of the film. Then, the two sets of second electric telescopic rods stop extending and retracting using the control panel. At this time, the operator can easily find the cut end of the film, which is convenient for the subsequent wrapping work of the next battery plastic shell. The cutting blades and protective tubes can prevent the operator or foreign objects from accidentally touching the cutting structure and can hold the cut end of the film, thus improving the practicality of the automatic wrapping device for battery plastic shells.

[0016] (2) This utility model is equipped with a rotating plate. According to the above operation, when wrapping the plastic shell of the battery, it is necessary to pull the film wound by a set of unwinding rollers so that one end of the film is attached to the side wall of the plastic shell of the battery through two sets of guide rollers. In this process, multiple sets of threaded blind holes and multiple sets of connecting screw threads are used to cooperate with each other. The operator can remove a set of unwinding rollers by hand counterclockwise and replace them. When the film wound on the side wall of the previous set of unwinding rollers is used up, the self-locking forward and reverse motor is started using the control panel. The output end of the self-locking forward and reverse motor can rotate multiple sets of unwinding rollers through the rotating plate. When the next set of unwinding rollers moves to the position of the previous set of unwinding rollers, the self-locking forward and reverse motor is stopped using the control panel. Multiple sets of connecting shafts make it possible to rotate multiple sets of unwinding rollers. The rotating plate can save the disassembly and assembly time of the roll structure and improve the working efficiency of the automatic wrapping device for the plastic shell of the battery.

[0030] In one embodiment, both sets of cutting blades 11 are located on the same horizontal line, ensuring that the two sets of cutting blades 11 can move towards each other to cut the film.

[0031] In one embodiment, a right-angle bracket 18 is installed on one side of the housing 1, and a self-locking forward and reverse motor 19 is installed on one side of the right-angle bracket 18. The output end of the self-locking forward and reverse motor 19 is fixedly connected to the rotating plate 13.

By using the rotating plate 13, the disassembly and assembly time of the roll structure can be saved, and the working efficiency of the automatic plastic coating device for the battery casing can be improved.

[0032] In one embodiment, multiple sets of threaded blind holes and multiple sets of connecting screws 21 are threaded together to facilitate adjustment of the usage position of the multiple sets of connecting screws 21.

[0033] In one embodiment, the control panel is electrically connected to the first electric telescopic rod 2, the geared motor 4, the electric heater 6, and the two sets of second electric telescopic rods 9 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the art. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0034] In one embodiment, four sets of support legs are installed on the lower part of the housing 1.

[0035] Working principle:

[0036] In actual use of the automatic battery plastic casing wrapping device, the battery plastic casing is first placed on the rotary table 5. Then, a set of unwinding rollers 22 pulls the film wound around the casing, causing one end of the film to adhere to the side wall of the battery plastic casing via two sets of guide rollers 8. Next, using the control panel, the geared motor 4 and electric heater 6 are activated. The output of the geared motor 4 can rotate the battery plastic casing via the rotary table 5, allowing the film to wrap around the side wall of the battery plastic casing. During this process, the electric heater 6 heats and shrinks the film, ensuring it is stably wrapped around the side wall of the battery plastic casing. Finally, using the control panel, the two sets of second... As the electric telescopic rod 9 extends, the opposing ends of the two sets of protective square tubes 12 first contact the film. Then, the two sets of cutting blades 11 continue to move towards each other. During this process, the four sets of mounting plates 14 and the two sets of protective square tubes 12 can compress the eight sets of telescopic springs 17. When the two sets of cutting blades 11 cut the film, the two sets of second electric telescopic rods 9 are shortened using the control panel. At this time, the eight sets of telescopic springs 17, under their own elastic force, can continue to push the two sets of protective square tubes 12 to clamp one end of the film. Then, the two sets of second electric telescopic rods 9 stop extending and retracting using the control panel. At this point, the operator can easily find the cut end of the film, facilitating the next step. The wrapping of the battery plastic casing utilizes a cutting blade 11 and a protective tube to prevent accidental contact with the cutting structure by operators or foreign objects. The cut end of the film is also held, improving the practicality of the automatic wrapping device. Furthermore, as described above, wrapping the battery plastic casing requires pulling a set of unwinding rollers 22 to wind the film, causing one end of the film to adhere to the side wall of the battery plastic casing via two sets of guide rollers 8. During this process, multiple sets of threaded blind holes and multiple sets of connecting screws 21 are used in conjunction, allowing the operator to manually unwind a set of unwinding rollers 22 counterclockwise. When the film wrapped around the side wall of the pre-set unwinding roller 22 is used up, the self-locking forward and reverse motor 19 is activated using the control panel. The output end of the self-locking forward and reverse motor 19 can rotate multiple sets of unwinding rollers 22 via the rotating plate 13. When the next set of unwinding rollers 22 moves to the position of the pre-set unwinding rollers 22, the self-locking forward and reverse motor 19 is stopped using the control panel. Multiple connecting shafts 20 enable the rotation of multiple sets of unwinding rollers 22. The rotating plate 13 can save the disassembly and assembly time of the roll structure and improve the working efficiency of the automatic wrapping device for battery plastic casing.
