Description

Technical Field

[0001] The utility model relates to the technical field of powder spraying devices, in particular to a powder spraying device for a new energy battery box. Background Art

[0002] A lithium battery is a battery with a lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. When installing lithium batteries, generally multiple lithium batteries are embedded inside a lithium battery box. When the lithium battery box is processed, powder needs to be sprayed on some of its parts. For the parts that do not need powder spraying, a shielding plate is generally used for shielding, and the area of the existing shielding plate is fixed.

[0003] The patent with the application number 202222437406.9 discloses a shielding device for powder spraying of a new energy vehicle lithium battery box, which includes a bottom plate. The top of the bottom plate is fixedly connected with three partition plates. The top of the partition plate is fixedly connected with a top plate, and a spraying port is opened on the top plate; on the left and right sides of the top of the top plate are respectively fixedly connected with strip-shaped baffles, and a shielding plate is slidably connected between the two strip-shaped baffles. The shielding plate is in contact with the top of the top plate. There are two shielding plates, and the tops of the two shielding plates are respectively fixedly connected with limit plate strips. A sliding plate is slidably connected between the limit plate strips, and the sliding plate is in contact with the top of the shielding plate.

[0004] The above technical solution uses a slidably arranged baffle to shield the powder spraying of battery boxes with different positions and sizes. However, since the heights of battery boxes with different sizes are different, when the distance between the baffle and the battery box is too large, the powder will float to the battery box along the bottom of the baffle during powder spraying processing, resulting in poor shielding effect for powder spraying processing of battery boxes with different sizes. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a powder spraying device for a new energy battery box aiming at the deficiencies of the prior art. Through the cooperation of the lead screw and the sliding part structure in the chute with the gear and the toothed belt structure, the function of driving the lead screw to rotate by a knob to lift the fixed plate is realized, and the problem of being unable to shield the powder spraying of battery boxes with different heights is solved.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A powder spraying device for a new energy battery box, which includes a powder spraying box and a powder spraying machine fixed on the top end of the powder spraying box. Both sides of the inner wall of the powder spraying box are provided with chutes, and discharge slots are opened at both ends of the powder spraying box. A fixed plate is installed between the two chutes on the same side, and a lead screw for driving the fixed plate to lift is embedded in the chute. The two ends of the fixed plate close to each other are damping inserted with sliding plates, and a plurality of baffles are detachably installed in the discharge slots.

[0007] Preferably, a conveyor belt is embedded at the bottom end of the powder spraying box, and a motor for driving the conveyor belt is fixed to the outer wall of the powder spraying box.

[0008] Furthermore, sliding parts that fit and plug into the sliding grooves are fixed at both ends of the fixing plate, and the lead screw is threadedly plugged into the sliding parts.

[0009] Still further, the top end of the lead screw passes through the powder spraying box and is fixedly sleeved with a gear, and a toothed belt is meshingly sleeved between two adjacent gears.

[0010] Still further, knobs are fixedly installed at the top ends of two lead screws on the same side, and a battery box body is arranged at the top end of the conveyor belt.

[0011] Still further, the sliding plate has a T-shaped structure and is clamped in the fixing plate, and a convex part is installed at the top end of the sliding plate.

[0012] Still further, card slots larger than a semi-circle are opened at the top wall of the discharge chute and the bottom ends of a plurality of baffle plates, and clamping parts that fit and plug into the card slots are fixed at the top ends of the plurality of baffle plates.

[0013] The beneficial effects of the present utility model are as follows:
