[0045] (4) After the plastic spraying operation is completed, the first lifting mechanism 5, the first transverse moving mechanism 6, the second lifting mechanism 9, the second transverse moving mechanism 8 and the angle adjusting mechanism 10 are reset to the initial positions, the door of the plastic spraying chamber 2 is opened, the longitudinal conveying mechanism 3 moves the machine tool body 4 subjected to the plastic spraying out of the plastic spraying chamber 2, and the machine tool body 4 subjected to the plastic spraying is lifted to the storage area of the factory building by using the overhead crane.

[0046] Through the above use method of the embodiment 2, it can be known that the machine tool body plastic spraying device has the following advantages: Firstly, the first plastic spraying mechanism 7 can perform the plastic spraying operation on the top surface of the machine tool body 4. The second plastic spraying mechanism 20 can perform the plastic spraying operation on the transverse outer side surface, the longitudinal outer side surface, the transverse inner side surface, the longitudinal inner side surface and the inner top surface of the machine tool body 4.

Therefore, the use flexibility of the device is improved.

[0048] Thirdly, by using the angle adjusting mechanism 10 to adjust the plastic spraying direction of the second plastic spraying mechanism 20, the plastic spraying range of the second plastic spraying mechanism 20 can be expanded, and the use flexibility of the second plastic spraying mechanism 20 is improved.

[0049] Embodiment 3: This embodiment 3 is further improved on the basis of embodiment 2: Referring to Figure 4 The spraying chamber 2 is also provided with a covering mechanism 30, which comprises a cover plate 301 and an extension piece 302. The cover plate 301 is horizontally slidably connected with the ground 1. The extension piece 302 can be an oil cylinder, an air cylinder or an electric cylinder. The top end of the extension piece 302 is rotatably connected with the bottom of the cover plate 301, and the bottom end of the extension piece 302 is rotatably connected with the bottom of the foundation pit 11.

[0050] In the use method of embodiment 2, in step (1), the covering mechanism 30 is also needed to open the foundation pit 11. In step (4), the covering mechanism 30 is also needed to cover the foundation pit 11 again. Specifically, when the extension piece 302 is extended, the extension piece 302 pushes the cover plate 301 to horizontally slide and cover the foundation pit 11; when the extension piece 302 is shortened, the extension piece 302 pulls the cover plate 301 to reversely horizontally slide and open the foundation pit 11. Figure 5 The state of the extension piece 302 being shortened, Figure 4 The state of the extension piece 302 being shortened and the cover plate 301 opening the foundation pit 11.

[0051] The setting of the covering mechanism 30 can cover the foundation pit 11 and protect the second lifting mechanism 9, the second transverse moving mechanism 8 and the second spraying mechanism 20 in the foundation pit 11, which is beneficial to improve the safety.

[0052] Because the extension piece 302 in the covering mechanism 30 is located inside the foundation pit 11, it does not need to occupy the space above the ground 1, which is beneficial to improve the space utilization rate; and it can also avoid the collision of the ground 1 equipment with the extension piece 302, which can improve the protection effect of the extension piece 302 and improve the use safety.

[0053] Further, referring to Figure 5 The cover plate groove 12 is provided on the ground 1, the groove bottom of the cover plate groove 12 is provided with the foundation pit 11, the transverse groove walls (including the left groove wall and the right groove wall) of the cover plate groove 12 are both provided with sliding grooves 13, referring to Figure 5 The transverse two ends of the cover plate 301 are both inserted into the sliding grooves 13, the cover plate 301 is horizontally slidably matched with the sliding grooves 13 along the longitudinal direction, and the top surface of the cover plate 301 is flush with the ground 1.

[0054] By setting the cover plate groove 12, the cover plate 301 can be hidden in the cover plate groove 12, avoiding the cover plate 301 protruding from the ground 1, which is beneficial to further improve the space utilization rate.
