The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a vacuum coating apparatus for plastic caps, such as... Figure 1-4As shown, the vacuum coating apparatus for plastic caps includes: a vacuum coating machine body 1, which includes a coating chamber 101, a vacuum pumping device 102, and a plating solution spraying device 103, both of which are mounted on the vacuum coating machine body 1; two placement shaft tubes 2 symmetrically and rotatably mounted on the coating chamber 101; multiple support plates 3 fixedly mounted on the placement shaft tubes 2; multiple placement racks 4 respectively mounted on the multiple support plates 3, which are used to place plastic bottle caps; and a rotation mechanism mounted on the coating chamber 101 and the two placement shaft tubes 2, which drives the plastic caps placed on the placement racks 4 to rotate.

[0022] In this embodiment, when vacuum coating the plastic cap, the plastic cap is placed on the placement rack 4, and then the placement rack 4 is placed on the support plate 3. The protective door on the vacuum coating machine body 1 is closed. The vacuum coating machine body 1 can perform vacuum coating on the plastic cap. The vacuum pumping device 102 evacuates the coating tank 101, and the plating solution spraying device 103 sprays the plating solution into the coating tank 101, thus smoothly coating the plastic cap. The working principle of the vacuum coating machine body 1 is existing technology and will not be described in detail here. When coating the plastic cap, the controller starts the rotating mechanism to drive the placement shaft tube 2 to rotate slowly, thereby driving the plastic cap on the placement rack 4 to rotate slowly. During rotation, because the speed is slow enough, the plastic cap will not shift randomly on the placement rack 4. The rotation speed can be adjusted according to actual needs, thereby adjusting the position of the plastic cap so that the plastic cap is evenly covered by the plating solution, improving the uniformity of the plastic cap coating, and thus improving the effect of vacuum coating on the plastic cap.

[0023] In a further preferred embodiment of the present invention, a plurality of positioning blocks 401 are provided on the placement rack 4, and a plastic cover is placed on the positioning block 401. The positioning block 401 is used to limit the placement of the plastic cover.

[0024] In this embodiment, when placing the plastic cap, the plastic cap is placed on the positioning block 401. The positioning block 401 can limit the placement of the plastic cap and facilitate the placement of the plastic cap by the staff, while avoiding contact between different plastic caps.

[0025] In a further preferred embodiment of the present invention, the rotating mechanism includes: a motor 5 fixedly installed at the bottom of the coating box 101; a plurality of pulleys 6 respectively fixedly sleeved on the output shaft of the motor 5 and the two placement shaft tubes 2; and two belts 7 sleeved on the plurality of pulleys 6.

[0026] In this embodiment, when using the rotating mechanism, the motor 5 is started by the controller. Under the interaction of the pulley 6 and the belt 7, the two placement shaft tubes 2 are driven to rotate slowly, which in turn drives the plastic cover on the placement rack 4 to rotate slowly. This allows the position of the plastic cover to be adjusted so that the plastic cover is evenly covered by the plating solution, improving the uniformity of the plastic cover coating and thus improving the effect of vacuum coating on the plastic cover.

[0027] In a further preferred embodiment of the present invention, a positioning connection mechanism is provided on the support plate 3 and the placement rack 4. The positioning connection mechanism is used to position the placement rack 4 on the support plate 3. The positioning connection mechanism includes: a positioning strip 8 fixedly installed on the top of the support plate 3; and a positioning frame 9 fixedly installed on the bottom of the placement rack 4. The positioning frame 9 and the positioning strip 8 are adapted to each other.

[0028] In this embodiment, when the placement rack 4 is placed on the support plate 3, the positioning rack 9 and the positioning strip 8 are connected and positioned so that the placement rack 4 can be positioned on the support plate 3, which facilitates the placement and removal of the placement rack 4 and makes it easier to load and unload the plastic cover.

[0029] In a further preferred embodiment of this utility model, a drying mechanism is provided on the coating box 101. The drying mechanism is used to dry the plastic cover after coating. The drying mechanism includes: a hot air blower 10 disposed below the coating box 101, with a horizontal pipe 11 fixedly installed on the air outlet end of the hot air blower 10; and two connecting pipes 12 fixedly installed at the bottom of the coating box 101. Both connecting pipes 12 are connected to the horizontal pipe 11, and the two horizontal pipes 11 are respectively sealed and rotatably connected to the two placement shaft pipes 2.

[0030] In this embodiment, when water stains adhere to the surface of the plastic cap after vacuum coating, the control valve on the connecting pipe 12 is opened, and the hot air blower 10 is started by the controller. Hot air enters the connecting pipe 12 through the horizontal pipe 11, then enters the placement shaft pipe 2, and finally blows onto the surface of the plastic cap through the air outlet 14 on the drying pipe 13, thereby drying the plastic cap and facilitating subsequent operations for the staff, providing convenience for the staff.

[0031] In a further preferred embodiment of the present invention, a filter box 15 is provided at the air inlet end of the hot air blower 10. The filter box 15 is provided with a filter plate 1501 and a drying plate 1502. The filter plate 1501 is used to filter impurities in the air drawn in by the hot air blower 10, and the drying plate 1502 is used to dry the moisture in the air drawn in by the hot air blower 10.

[0032] In this embodiment, the filter plate 1501 is used to filter impurities in the air drawn by the hot air blower 10, and the drying plate 1502 is used to dry the moisture in the air drawn by the hot air blower 10.

[0033] In a further preferred embodiment of this utility model, each of the two connecting pipes 12 is provided with a control valve, which is used for control operation.

[0034] In this embodiment, the control valve facilitates the control operation of the connecting pipe 12. When the plastic cap is dried, the control valve on the connecting pipe 12 is opened, and when the plastic cap is vacuum coated, the control valve on the connecting pipe 12 is closed.

[0035] In summary, compared with related technologies, this device can perform vacuum coating on plastic caps, and the placement of the plastic caps can be adjusted during the coating process to ensure that the plastic caps are evenly covered by the coating solution, thereby improving the uniformity of the coating and thus enhancing the vacuum coating effect on the plastic caps.
