[0031] In addition, the clamping block 206 has a "soil" - shaped structure. A sealing block 209 is slidably connected to the bottom end of the clamping block 206, and the sealing block 209 is fixedly connected inside the clamping seat 205. The clamping block 206 can cooperate with the sealing block 209 through the cylindrical through - hole on the inner side to realize the switching between the closed and open states of the clamping block 206.

[0033] Embodiment 2

[0034] As Figure 2 、 Figure 3 shown, on the basis of Embodiment 1, a spraying mechanism 6 is provided above the clamping mechanism 2, and the spraying mechanism 6 can perform spraying operations on the capacitor shell.

[0035] In this embodiment, the spraying mechanism 6 includes a sealing cover 601. The sealing cover 601 is connected to the top end inside the frame 1. A spray head 602 is fixedly connected inside the sealing cover 601. The spray head 602 is externally connected to a spraying device through a spraying pipeline. The structure of the sealing cover 601 can shield the capacitor shell to prevent paint from splashing during spraying. At the same time, the sealing cover 601 can drive the clamping block 206 through the bottom, so that the top end of the clamping seat 205 is opened and the dripping paint is collected.

[0036] It is worth mentioning that the discharge port 3 is arranged on the side of the rack 1, and the discharge plate 4 is fixedly connected to the rack 1, so that the capacitor shell can be conveniently discharged, the movement of the capacitor shell can be guided, and the completed capacitor shell can be collected through the collection structure arranged at the end of the discharge plate 4.

[0037] The spraying device for the film capacitor production is used, the capacitor shell is placed in the feeding frame 5 first, then the motor 214 is started, the motor 214 drives the driving gear 212 to rotate and drives the meshing gear ring 213 to rotate.

[0038] The end of the clamping block 206 below contacts the inner side of the capacitor shell.

At the same time, the air pump 211 continuously operates and exhausts the air in the support frame 201, and when the end of the clamping block 206 contacts the inner side of the capacitor shell, the clamping block 206 is adsorbed and clamped by the negative pressure in the support frame 201. Then the continuously rotating driving disc 203 drives the clamping seat 205 to move inward along the sliding groove 202 again.

[0039] After the clamping seat 205 above moves, the capacitor shell corresponds to the position of the sealing cover 601, and after the clamping seat 205 drives the capacitor shell to move outward, the capacitor shell moves into the sealing cover 601. At the same time, the sealing cover 601 pushes the clamping block 206 into the clamping seat 205, and the clamping block 206 approaches the sealing block 209 and seals the clamping block 206. At the same time, the clamping block 206 loses the limitation of the clamping block 206 at the top of the clamping seat 205 after moving, and the collection hole 210 is opened, so that the falling paint can be collected through the collection hole 210 during spraying.

[0040] After the clamping seat 205 on the side moves to the end, the clamping block 206 moves inward under the limitation of the discharge plate 4, and after the sealing block 209 seals the clamping block 206, the capacitor shell loses the adsorption of the negative pressure of the clamping block 206 and slides outward, so that the completed capacitor shell can be conveniently collected.
