[0021] As Figure 1 The utility model discloses a kind of enamelled tank production spraying devices, including moving component, telescopic component being set on moving component and spraying assembly being set in one end of telescopic component.

[0022] In this embodiment, the moving assembly includes a trolley 1, a first telescopic rod 2 arranged at one end of the trolley 1, and a storage tank 6 mounted at the other end of the trolley 1 opposite the first telescopic rod 2. In this embodiment, the storage tank 6 not only provides the glaze, but also acts as a counterweight to maintain the balance of the entire device. The trolley 1 has a square bottom plate and four pulleys 11 arranged at the corners of the bottom surface of the bottom plate. The pulleys 11 are connected to the bottom plate through universal joints, allowing the trolley 1 to freely slide on the ground. Preferably, limiters are arranged at the four corners of the bottom of the trolley 1. The limiters are limit rods 12 rotatably mounted on the bottom of the trolley 1. The length of the limit rods 12 is greater than the height of the bottom of the trolley 1, so that the limit rods 12 can be rotated to the ground. The limit rods 12 are also provided with locks, which in this embodiment are ratchet structures. The limit rods 12 can keep the trolley 1 stable in the working state, avoiding the movement of the trolley 1 affecting the stability of the spraying process.

[0023] The telescopic assembly includes a horizontally arranged second telescopic rod 3 parallel to the front-to-back direction of the trolley 1. One end of the second telescopic rod 3 is mounted at the top end of the first telescopic rod 2, and the other end is movably connected to the spraying assembly. Further, the second telescopic rod 3 is a multi-section telescopic rod, with the thinnest section connected to the first telescopic rod 2.
