At present, the capping of the coating bath in the electroplating production line is overall design, and the structure is heavy, can only wholly open and shut, leads to opening and shutting inefficiency, and assembly and later maintenance in earlier stage are comparatively difficult. Meanwhile, the existing tank cover is not enough in automation degree, needs manual intervention to open and close mechanically, and is not beneficial to improving the overall efficiency of the electroplating production line.

In order to solve the above problems, as shown in fig. 1 to 4, the present embodiment further discloses a cover of a plating tank, which includes a first support plate 11, a second support plate 12, a main shaft 2, an auxiliary shaft 3, a driving member 4, and a rolling shutter 5. The first support plate 11 and the second support plate 12 are oppositely disposed at both sides of the open end of the plating tank 10 in the length direction thereof. Both ends of the main shaft 2 are rotatably provided on first and second support plates 11 and 12, respectively, on first sides in the width direction of the plating tank 10. Both ends of the auxiliary shaft 3 are rotatably provided on second sides of the first support plate 11 and the second support plate 12 in the width direction of the plating tank 10, respectively. The main shaft 2 is in transmission connection with the auxiliary shaft 3, and the rotation directions of the main shaft and the auxiliary shaft are opposite. The driving member 4 is in transmission connection with the main shaft 2 to drive the main shaft 2 to rotate forwards or backwards. The fixed ends of the two roller shutters 5 are respectively wound on the main shaft 2 and the auxiliary shaft 3.

When the capping of closed coating bath is required, when main shaft 2 and auxiliary shaft 3 rotate synchronously, main shaft 2 rotates in the forward direction and auxiliary shaft 3 rotates in the reverse direction, two roller shutters 5 unreel simultaneously until the free ends of two roller shutters 5 abut against each other, so that the two roller shutters 5 are spliced together to form the capping of closed coating bath, thereby blocking the open end of coating bath 10. When the cover of the coating bath needs to be opened, the main shaft 2 and the auxiliary shaft 3 synchronously rotate, the main shaft 2 rotates reversely and the auxiliary shaft 3 rotates forwards, the two roller shutters 5 are wound simultaneously, the free ends of the two roller shutters 5 are far away from each other until the two roller shutters 5 are wound, and the cover of the coating bath is completely opened.

In this embodiment, the split design of the cover of the plating tank is realized by the two rolling shutters 5, the structure is simple, and the installation and the maintenance are convenient. Because two roller shutters 5 are synchronously unreeled or reeled, the opening and the closing are flexible, the opening and closing time is shortened, the opening and closing efficiency is improved, and the electroplating efficiency of the plating tank 10 is favorably improved.

It should be noted that the rolling shutter 5 is assembled by plastic or metal shutter sheets, and has low cost and good corrosion resistance.

Specifically, the first support plate 11 and the second support plate 12 are mounted on two sides of the opening end of the coating bath 10 by bolts or welding, and the main shaft 2 and the auxiliary shaft 3 are respectively winding and unwinding shafts of the two roller blinds 5. When the main shaft 2 and the auxiliary shaft 3 are unreeled, the two roller shutters 5 are gradually unfolded and flatly laid to the open end of the plating tank 10. When the free ends of the two rolling curtains 5 are abutted, the open end of the plating tank 10 can be completely sealed, and the tank cover of the plating tank is closed. When the main shaft 2 and the auxiliary shaft 3 are wound, the two roller shutters 5 are gradually wound and wound on the corresponding main shaft 2 or auxiliary shaft 3. When the free ends of the two rolling shutters 5 are respectively moved to the first side and the second side of the plating tank 10 in the width direction thereof, the opening of the tank cover of the plating tank is realized.

The cover of the plating tank of the embodiment also comprises a middle rotating shaft 6, the main shaft 2 is in transmission connection with the auxiliary shaft 3 through the middle rotating shaft 6, and the rotating directions of the main shaft 2 and the auxiliary shaft 3 are opposite.

As shown in fig. 2 and 4, the intermediate shaft 6 is disposed on the second support plate 12, and the intermediate shaft 6 is provided with a driven gear 61 and a driving pulley 62 along an axial direction thereof. The end of the main shaft 2 extending out of the second support plate 12 is provided with a driving gear 21, and the driving gear 21 is engaged with the driven gear 61. The shaft end of the auxiliary shaft 3 extending out of the second support plate 12 is provided with a driven pulley 31, and a driving pulley 62 is connected with the driven pulley 31 through a transmission belt 60.

Specifically, the intermediate shaft 6 is located on the second support plate 12 on the side close to the main shaft 2. The driven gear 61 on the intermediate rotating shaft 6 is connected with the driving pulley 62 as a whole and can rotate synchronously. The rotation directions of the main shaft 2 and the middle rotating shaft 6 are opposite through the meshed connection of the driving gear 21 and the driven gear 61. The intermediate rotating shaft 6 is connected with the auxiliary shaft 3 through the conveyor belt 60, so that the rotating directions of the intermediate rotating shaft 6 and the auxiliary shaft 3 are the same, and the rotating directions of the main shaft 2 and the auxiliary shaft 3 are opposite. The power transmission with a large center distance between the main shaft 2 and the auxiliary shaft 3 can be realized in a belt transmission mode, so that the transmission of the main shaft 2 and the auxiliary shaft 3 is more stable. Moreover, the belt transmission mode has the advantages of simple structure, convenient use and maintenance and the like.

In the present embodiment, both the roller blinds 5 slide on the top surfaces of the first support plate 11 and the second support plate 12 to complete the winding and unwinding of the roller blinds 5. In order to improve the efficiency of winding and unwinding the roller shutter 5, the tank cover of the coating tank further comprises a first belt pulley component and a sliding rod 7.

As shown in fig. 2 and 4, the first pulley assembly includes a first driving roller 22, a first driven roller 32, and a first connecting belt 20.

The first drive roller 22 is connected to the corresponding first driven roller 32 by the first connecting belt 20. The two sides of the free end of the rolling curtain 5 along the length direction of the plating tank 10 are connected with one end of the sliding rod 7, and the other ends of the two sliding rods 7 on the same side of the two rolling curtains 5 along the length direction of the plating tank 10 are respectively connected with the upper section and the lower section of the corresponding first connecting belt 20.

It should be noted that the first driving roller 22 is sleeved on the main shaft 2 and rotates synchronously with the main shaft 2. The first driven roller assembly further comprises a bearing, and the first driven roller 32 is sleeved on the auxiliary shaft 3 through the corresponding bearing, so that the auxiliary shaft 3 only supports the first driven roller 32 and cannot influence the rotation direction of the first driven roller 32. The first driving roller 22 rotates the first driven roller 32 via the first connecting belt 20. Therefore, the first drive roller 22 and the first driven roller 32 have the same rotational direction.

One end of the second horizontal section is connected to the upper or lower section of the first connecting band 20, and the other end of the second horizontal section is connected to the bottom of the vertical section.

When the first connecting belt 20 is wound between the first driving roller 22 and the first driven roller 32, the first connecting belt 20 may be divided into an upper section and a lower section. When the first driving roller 22 rotates, the upper and lower sections of the first belt 20 move in opposite directions, so that the two slide bars 7 connected to the upper and lower sections of the first belt 20 move in opposite directions, thereby moving the free ends of the two roller blinds 5 toward and away from each other.

In this embodiment, the fixed end of the roller shutter 5 can be wound and unwound by the synchronous rotation of the main shaft 2 and the auxiliary shaft 3. Meanwhile, when the main shaft 2 rotates, the sliding rod 7 can generate traction force on the free end of the roller shutter 5 through the first belt pulley component, and the winding and unwinding efficiency and stability of the roller shutter 5 are further improved.

Specifically, as shown in fig. 2 and 4, the first pulley assemblies of the present embodiment have two and are respectively disposed on both sides of the plating tank 10 in the longitudinal direction. The number of the sliding rods 7 is four correspondingly, and one sliding rod 7 is installed on each free end of each roller shutter 5 along two sides of the length direction of the plating tank 10 respectively, so that the free ends of the roller shutters 5 are stressed more evenly, and position deflection is avoided when the roller shutters 5 are wound and unwound along the length direction of the plating tank 10.

As shown in fig. 5 and 6, the tank cover of the plating tank further includes a second pulley assembly including a second driving roller 23, a second driven roller 33, and a second connecting belt 30. The two ends of the main shaft 2 and the auxiliary shaft 3 are respectively provided with a second driving roller 23, the two sides of the first supporting plate 11 and the second supporting plate 12 along the width direction of the coating bath 10 are respectively provided with a second driven roller 33 in a rotating mode, the second driving rollers 23 are in one-to-one correspondence with the second driven rollers 33, one end of a second connecting belt 30 is sequentially wound on the corresponding second driving rollers 23 and the corresponding second driven rollers 33, and the other end of the second connecting belt 30 is connected with the corresponding roller shutters 5.

Specifically, the second connecting belt 30 is a synchronous belt, the second driving roller 23 and the second driven roller 33 are synchronous belt wheels, and one end of the second connecting belt 30 is fixedly wound on the second driving roller 23. A plurality of fixing blocks are mounted on the outer surface of the second connecting belt 30 at intervals along the extending direction thereof, and each fixing block is connected with a corresponding curtain sheet on the roll screen 5. So that the main shaft 2 and the auxiliary shaft 3 can complete the winding and unwinding of the roller shutter 5 through the second belt wheel assembly.

After the first supporting plate 11, the second supporting plate 12 and the rolling curtain 5 are installed at the opening end of the plating tank 10, there are large gaps between the rolling curtain 5 and the opening end of the plating tank 10 at the first side and the second side of the plating tank 10 in the width direction, and in order to prevent the plating solution in the plating tank 10 from overflowing or the volatilized plating solution from escaping, the tank cover of the plating tank of this embodiment further includes a sealing plate 8 and a ventilation pipeline 9.
