DETAILED DESCRIPTION

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figure 1 The structure of automatic opening and closing cover of an electroplating drum shown in the figure comprises a lifting mechanism 1, an opening and closing mechanism 2 and a drum 3. The lifting mechanism 1 is installed on the side of the drum 3 offset at a certain angle, and the opening and closing mechanism 2 is installed at the lower end of the lifting mechanism 1. The lifting mechanism 1 drives the opening and closing mechanism 2 to rise or fall, so that it approaches or moves away from the drum 3, thereby realizing the opening or closing operation of the drum 3.

[0029] like Figure 1 , Figure 4As shown, the lifting mechanism 1 includes a fixed platform 11, which is installed above the roller 3 through a bracket (not shown). The fixed platform 11 is a rectangular hollow shell, and a lifting drive member 12 is installed at the center of the bottom plate of the fixed platform 11. The lifting drive member 12 is a cylinder, and the telescopic end of the cylinder is vertically downward. Four lifting guide rods 13 are symmetrically installed around the lifting drive member 12, and the lifting guide rods 13 are installed on the fixed platform 11 through linear bearings.

[0030] like Figure 1 , Figure 4-Figure 6 As shown, the opening and closing mechanism 2 includes a mounting platform 21, which is a rectangular plate. A connecting bracket 211 is fixed at the center of the mounting platform 21, and the connecting bracket 211 is connected to the telescopic end of the lifting drive member 12. The four corners of the mounting platform 21 are respectively connected to the lower end of the lifting guide rod 13 to improve the stability of the opening and closing mechanism 2 when lifting.

[0031] like Figure 1 , Figure 4 , Figure 5 As shown, three connecting holes are opened on the mounting platform 21, and the connecting holes are evenly distributed along the length direction of the mounting platform 21. A rotating shaft 23 is rotatably installed at each connecting hole through a bearing seat 22. An Ω-shaped rotating claw 27 is fixed to the lower end of each rotating shaft 23, and a crank 24 is fixed to the upper end of each rotating shaft 23. A connecting rod 25 is connected between the three cranks 24, and the connecting rod 25 can drive the three rotating shafts 23 to rotate synchronously through the crank 24.

[0032] like Figure 1 , Figure 4 , Figure 6 As shown, a switch driver 26 is installed on the lower side of the mounting platform 21. The switch driver 26 is a cylinder, and the fixed end of the cylinder is hinged to the mounting platform. A crank 24 is fixed to the side of the leftmost rotating shaft 23, and the telescopic end of the switch driver 26 is hinged to the free end of the crank 24. The switch driver 26 telescopes to drive the crank 24 to rotate, and then drives the rotating claw 27 to rotate 90° through the rotating shaft 23.

[0033] like Figure 2 As shown, a cavity 231 is formed at the lower end of the rotating shaft 23 along the axis of the rotating shaft 23, and an elastic ejector pin 28 is slidably installed in the cavity 231. A compression spring 29 is installed between the upper end of the elastic ejector pin 28 and the top of the cavity 231, thereby applying downward pressure on the elastic ejector pin 28; the lower end of the elastic ejector pin 28 extends out of the top of the rotating claw 27.

[0034] like Figure 3As shown, the drum 3 is a hexagonal hollow shell, one side of the hexagonal prism is provided with an opening, a door cover 32 is installed at the opening of the drum 3, three rotating bolts 34 are installed on the door cover 32, and the rotating bolts 34 are rotatably installed on the door cover 32 through locking bolts 35. First ribs 31 are fixed on both sides of the long side of the opening of the drum 3, and three horizontal first slots 311 are respectively provided on the first ribs 31 on both sides, and the first slots 311 are located on both sides of the rotating bolt 34. Second ribs 33 are fixed on both sides of the long side of the door cover 32, and second slots 331 cooperating with the first slots are respectively provided on the second ribs 33 on both sides. The end of the rotating bolt 34 passes through the second slot 331 and is engaged with the first slot 311, so as to realize the locking of the door cover 32 and the drum 3.

[0035] The number of the rotating bolts 34 can be selected according to the length of the drum 3 . The longer the length of the drum 3 is, the greater the number of the rotating bolts 34 is. The number and position of the rotating claws 27 are determined according to the position of the rotating bolts 34 .

[0036] The working principle of the embodiment of the present application is as follows:

[0037] like Figure 1-Figure 8 As shown, when the door cover 32 is opened, the lifting mechanism 1 drives the opening and closing mechanism 2 to descend, so that the rotating claw 27 is perpendicular to the rotating bolt 34 and is clamped on the upper side of the rotating bolt 34, and the elastic top pin 28 is pressed against the locking bolt 35. The switch driving member 26 drives the rotating bolt 34 to rotate 90° counterclockwise, so that the rotating bolt 34 is separated from the first retaining edge 31, and the two ends of the rotating claw 27 are clamped into the second clamping groove 331. The lifting mechanism 1 drives the opening and closing mechanism 2 to lift and remove the door cover 32 from the drum 3. At this time, the cooperation between the elastic top pin 28 and the rotating claw 27 keeps the cover plate 32 fixed and does not deviate.

[0038] When closing the cover door 32, the lifting mechanism 1 drives the opening and closing mechanism 2 to descend, so that the door cover 32 covers the opening of the drum 3. The switch driving member 26 drives the rotating bolt 34 to rotate 90° clockwise, so that the rotating claw 27 is separated from the second retaining edge 33, and the two ends of the rotating bolt 34 are re-engaged in the first clamping groove 311. The lifting mechanism 1 drives the opening and closing mechanism 2 to lift up, and the door cover 32 is closed.

[0039] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0040] 1. By setting an elastic ejector pin at the center of each rotating claw, the force on the door cover is more stable and balanced when opening and closing, thus avoiding deformation of the door cover and improving the accuracy of door cover positioning;

[0041] 2. By combining the elastic ejector pin with the rotating claw, there is no need to set a positioning rod separately. The position of the multi-head rotating bolt can be reasonably set according to the length of the roller to meet customer needs;

[0042] 3. The connecting rod drives multiple rotating bolts to realize the opening and closing of the bolts, which reduces the use of cylinders and saves costs.

[0043] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
