Description

Technical Field

[0001] The utility model relates to the technical field of vacuum coating machines, in particular to a vacuum coating machine for polymer plastic products. Background Art

[0002] Although plastic can replace metal in many occasions, it obviously lacks the texture of metal. Therefore, certain methods are needed to plate a layer of metal (aluminum, zinc, copper, silver, gold, chromium, etc.) on the plastic surface. One method is to use methods similar to chemical plating and electroplating. Another method is to vacuum spray metal on the plastic surface - that is, in a vacuum state, the metal is melted and deposited on the plastic surface in the form of molecules or atoms to form a 5-10um metal film. At this time, a vacuum coating machine will be used. Vacuum coating machine mainly refers to a type of coating that needs to be performed under a higher vacuum degree. There are many types, including vacuum resistance heating evaporation, electron gun heating evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition and ion beam sputtering. The main idea is to divide it into evaporation and sputtering. Evaporation coating generally heats the target material to evaporate the surface components in the form of atomic groups or ions.

The utility model utilizes the mutual cooperation of the universal wheel, the fixed plate, the connecting plate, the fixed shaft, the mounting column, the fixed block, the limiting rod, the spring and the pulling rope, the connecting plate drives the universal wheel to rotate in a circle with the fixed shaft as the center, the mounting column and the limiting rod limit the position of the connecting plate, which is conducive to storing the universal wheel and facilitating the increase of the stability of the coating machine body.

[0004] However, the above patent still has certain disadvantages when in use: when adjusting the support columns, personnel are required to rotate them one by one. At this time, after one group of support columns are rotated and stored, the other support columns are not processed, which will cause a certain height difference in the entire device, thereby causing the device to tilt, affecting the safety of the device. When multiple personnel are used to operate at the same time, the device may tilt due to poor synchronization of personnel operations. The overall adjustment stability and balance of use are not very good, resulting in the overall effect of the device when used is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0028] According to an embodiment of the utility model, a vacuum coating machine for polymer plastic products is provided.

[0029] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, a polymer plastic product vacuum coating machine according to an embodiment of the utility model includes a vacuum coating machine body 1 and a carrying plate 2, a mounting ring 13 is fixedly installed at the middle position of the bottom of the carrying plate 2, and a plurality of groups of driving screw barrels 10 are rotatably connected around the surface of the mounting ring 13. A transmission gear 14 is welded at the top of the driving screw barrel 10, and a driving gear 15 is meshed and connected between the transmission gears 14. The driving gear 15 and the transmission gear 14 are both located inside the carrying plate 2, one end of the driving gear 15 passes through one side of the carrying plate 2 and is connected to the motor 16, a driving screw 9 is rotatably connected to the bottom end of the driving screw barrel 10, a bottom plate 11 is welded at the bottom end of the driving screw 9, telescopic rods 12 are symmetrically installed on both sides of the bottom plate 11, and the top of the telescopic rod 12 is fixedly connected to the bottom of the carrying plate 2.

[0030] In one embodiment, receiving grooves 6 are symmetrically opened around the bottom of the supporting plate 2, guide grooves 5 are symmetrically opened on both sides of the receiving grooves 6, a movable plate 7 is slidably connected between the guide grooves 5, an adjusting screw 4 is rotatably connected to the bottom of the movable plate 7, and a lockable universal wheel 8 is installed at the bottom of the movable plate 7.

[0031] In one embodiment, a driving groove 3 is provided on one side of the carrying plate 2 above the accommodating groove 6 . The driving groove 3 is provided to facilitate personnel to rotate the adjusting screw 4 .

[0032] In one embodiment, the depth of the accommodating groove 6 is greater than the height of the movable plate 7 and the lockable universal wheel 8. The depth is set to ensure that when the movable plate 7 drives the lockable universal wheel 8 to be stored, the lockable universal wheel 8 will not protrude and affect the overall stability.

[0033] In one embodiment, a cavity for installing the power supply machine 16 is provided inside the bearing plate 2. The provision of the cavity facilitates the installation of the structure.

[0034] In one embodiment, a heat dissipation hole for dissipating heat from the power supply motor 16 is provided on the side of the support plate 2. The heat dissipation hole is provided to facilitate heat dissipation during operation of the motor 16 and to avoid damage to the motor 16 caused by excessive temperature.

[0035] In one embodiment, an anti-skid pad is provided at the bottom of the base plate 11. The anti-skid pad is provided to enhance the friction with the ground, thereby improving the stability during support.

[0036] Working principle: In actual use, the vacuum coating machine can normally process the polymer plastic material accordingly. When the vacuum coating machine moves, the movable plate 7 can be moved downward as a whole by rotating the adjusting screw 4, so that the lockable universal wheel 8 can smoothly protrude from the driving slot 3. Then, the driving gear 15 can be driven to rotate by the operation of the motor 16, and the driving gear 15 can drive the transmission gear 14 on its outer side to rotate. The rotation of the transmission gear 14 can drive the driving screw barrel 10 at the bottom to rotate. Since the transmission screw 9 inside the driving screw barrel 10 is restricted by the telescopic rod 12, the driving screw 9 can be moved downward. The rotational force transmitted by the cylinder 10 is converted into the power for up and down movement, thereby realizing the synchronous lifting operation of multiple sets of transmission screws 9, so that the base plate 11 is away from the ground and the lockable universal wheels 8 are in contact with the ground, which is convenient for subsequent moving operations. After the movement is completed, the above operation can be performed in reverse to synchronously make the multiple sets of base plates 11 contact the ground, thereby realizing the fixing operation of the device. The overall synchronous operation can effectively avoid the problem of device tilting caused by the difference in the movement of the base plate 11, ensure the stability during adjustment, and facilitate better use. The device as a whole has the advantages of synchronous adjustment of the legs, high adjustment stability, and good stability in use.
