Description

Technical Field

[0001] The invention belongs to the field of flaking machines, and in particular relates to a flipping mechanism of a flaking machine. Background Art

[0002] In the metallurgical industry, the stripping unit is a cathode copper automatic stripping device. The flipping mechanism is an important part of the stripping unit of the stripping machine. Its operating principle is that the connecting arm connects the motor and the driving shaft of the flipping mechanism, and then the motor drives the driving shaft to rotate, so that the flipping mechanism completes the flipping action. Its function is to flip the cathode copper after stripping 90°, place it on the electro-copper conveyor chain, and send it to the next process. In the prior art, the driving shaft of the flipping mechanism of the stripping unit is made of 45# steel. During operation, the cathode copper after high-temperature washing enters the stripping unit, and inevitably brings in some acid. The driving shaft made of 45# steel is very easy to corrode in an acidic environment. After a long period of corrosion, the shaft diameter becomes smaller, corrosion fatigue occurs, and the driving shaft breaks, which seriously affects the operation of the stripping unit. Due to the small space inside the stripping unit, the maintenance space is insufficient, and the mass and volume of the entire flipping mechanism are too large, it is necessary to remove more other parts of the stripping unit before disassembly and replacement. The steps are cumbersome and inconvenient, and the maintenance time is as long as 10-15 hours. Summary of the invention

[0003] The purpose of the invention is to provide a peeling machine turning mechanism which has strong corrosion resistance and is easy to disassemble, assemble and overhaul.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: the splice slot frames are arranged at intervals on the rotating shaft, the splice slot frames include a splice slot bracket fixedly connected to the rotating shaft, the splice slots are arranged along the radial direction of the rotating shaft and the splice slot bracket, one end is fixed on the splice slot bracket, and the other end is free, the splice slots arranged on both sides have groove directions opposite to each other and the circumferential positions are in the same position, the rotating shaft includes a coaxially connected intermediate shaft and end shafts at both ends, the intermediate shaft and the end shafts are detachably fixedly connected, the length of the intermediate shaft matches the spacing between the splice slots of the same-positioned parts on the opposite side, the splice slot bracket on the opposite side is fixed on the end shaft at the corresponding end, the end shafts at both ends are rotatably arranged on the bearing seats at the ends and one of the end shafts is connected to the power shaft.

[0005] In the above scheme, the cathode copper after high-temperature washing will bring in some acid when it enters the flipping mechanism. The dripping area of ​​these acid liquids is the area between the joint grooves of the isotropic parts on the opposite sides. The acid liquid can only drip and corrode the intermediate shaft on the rotating shaft, and the detachable fixed intermediate shaft and the end shafts at both ends are convenient for disassembly and maintenance. The intermediate shaft can be disassembled and assembled separately. If there is interference between the connecting ends of the intermediate shaft and the end shafts, only one side of the end shaft and its bearing seat need to be removed to complete the disassembly and assembly of the intermediate shaft. Fewer other parts need to be removed during the disassembly and assembly process, which simplifies the maintenance process, reduces the difficulty of maintenance, and greatly shortens the maintenance time of the rotating shaft damaged by acid corrosion.

[0009] Combined with Figures 1 to 4 The present invention is further described as follows:

[0010] A flapper turning mechanism, characterized in that: a sheet-stripping machine flipping mechanism is provided with a sheet-stripping slot frame 20 at intervals on a rotating shaft 10, the sheet-stripping slot frame 20 comprises a sheet-stripping slot bracket 21 fixedly connected to the rotating shaft 10, the sheet-stripping slots 22 are arranged along the radial direction of the rotating shaft 10 and the sheet-stripping slot bracket 21, one end of the sheet-stripping slot bracket 21 is fixed to the sheet-stripping slot bracket 21, and the other end is free, the notch directions of the sheet-stripping slots 22 arranged on both sides are opposite to each other and the circumferential positions are in the same position, the rotating shaft 10 comprises a coaxially connected intermediate shaft 11 and end shafts 12 at both ends, the intermediate shaft 11 and the end shafts 12 are detachably fixedly connected, the length of the intermediate shaft 11 matches the spacing between the sheet-stripping slots 22 of the same position on the opposite side, the sheet-stripping slot bracket 21 on the opposite side is fixed to the end shaft 12 at the corresponding end, the end shafts 12 at both ends are rotatably provided on the bearing seats at the ends thereof and one of the end shafts 12 is connected to the power shaft.

[0011] In the above scheme, if Figure 2As shown, the cathode copper after stripping falls into the splice grooves 22 arranged on both sides, and the power shaft drives the flipping mechanism to rotate to flip the cathode copper after stripping 90 degrees and place it on the electrolytic copper conveying chain to be sent to the next process. After high-temperature washing, the cathode copper enters the flipping mechanism, and inevitably brings in some acid liquid. The dripping area of ​​these acid liquids is the area between the splice grooves 22 of the corresponding parts on the opposite sides. Since the length of the intermediate shaft 11 matches the spacing between the splice grooves 22 of the corresponding parts on the opposite sides, the part of the rotating shaft 10 corresponding to the area between the splice grooves 22 of the corresponding parts on the opposite sides is the intermediate shaft 11. The acid liquid can only drip and corrode the intermediate shaft 11 on the rotating shaft 10, so as to ensure the corrosion of the intermediate shaft 11. The end shafts 12 at both ends are protected. The maintenance caused by acid corrosion only requires the replacement of the intermediate shaft 11, and the intermediate shaft 11 is detachably connected to the end shafts 12 at both ends. The sheet groove bracket 21 on the opposite side is fixed to the end shaft 12 at the corresponding end. No other components are provided on the intermediate shaft 11, and the intermediate shaft 11 can be disassembled and assembled separately. If there is interference between the connecting ends of the intermediate shaft 11 and the end shaft 12, only the end shaft 12 and its bearing seat on one side need to be removed to complete the disassembly and assembly of the intermediate shaft 11. Fewer other components need to be removed during the disassembly and assembly process, which simplifies the maintenance process, reduces the difficulty of maintenance, and greatly shortens the maintenance time of the shaft damage caused by acid corrosion.

[0012] The web slot bracket 21 includes an annular frame 213 and a sleeve 211, and the annular frame 213 and the sleeve 211 are connected as a whole by a radial spoke 212. The inner end of the web slot 22 is fixed on the annular frame 213, and the sleeve 211 is sleeved on the end shaft 12. In the axial length direction, the connecting part of the end shaft 12 and the intermediate shaft 11 is located between the annular frame 213 and the sleeve 211. The dripping area of ​​the acid is the area between the annular frames 213 arranged on both sides. Since the connecting part of the end shaft 12 and the intermediate shaft 11 is located between the annular frame 213 and the sleeve 211 in the axial length direction, the acid is prevented from dripping onto the end shaft 12 along the inner wall of the annular frame 213. The acid can only drip on the rotating shaft 10 to corrode the intermediate shaft 11, thereby protecting the end shafts 12 at both ends.

[0013] The radial spoke 212 is formed into an L-shaped rod by an axial section 212a and a radial section 212b. The axial section 212a is connected to the annular frame 213, and the radial section 212b is connected to the shaft sleeve 211. The above scheme meets the requirements of force strength and ensures that there is a certain distance between the annular frame 213 and the shaft sleeve 211 in the axial length direction.

[0014] There are four splice slots 22 arranged on the outer frame 213 of the splice slot bracket 21 and the gaps are 90°. The flipping mechanism of the stripping unit needs to flip the cathode copper after stripping by 90° and place it on the electrolytic copper conveyor chain to send it to the next process. Four splice slots 22 are arranged and the gaps are 90°, which ensures that when the cathode copper falls into the splice slot and flips 90°, there are still splice slots waiting for the cathode copper to fall in at the cathode copper falling position.

[0015] The intermediate shaft 11 and the end shafts 12 at both ends are connected in a detachable manner by a flange-type coupling 30, which is used to axially fix the various sections of the rotating shaft 10 and transmit torque. This connection form meets the requirements of shaft position accuracy and ensures that the force strength meets the requirements, while facilitating the disassembly, assembly and maintenance of the intermediate shaft 11.

[0016] The shaft ends of the intermediate shaft 11 and the end shafts 12 at both ends are arranged as plug-in holes and pin shafts that fit into each other. The hole core of the plug-in hole, the shaft core of the pin shaft and the hole core are coaxial with the intermediate shaft 11. The depth of the plug-in hole is greater than or equal to the length of the pin shaft. In the above scheme, the depth of the plug-in hole is greater than or equal to the length of the pin shaft to ensure that the pin shaft can be fully inserted into the plug-in hole. This connection form meets the requirements of shaft position accuracy and ensures the concentricity of the intermediate shaft 11 and the end shafts 12 at both ends, avoiding eccentricity, so that the rotating shaft 10 is not easily damaged after long-term operation.

[0017] The intermediate shaft 11 can be made of 06Cr19Ni10 material. 06Cr19Ni10 is a corrosion-resistant material. The intermediate shaft 11 made of 06Cr19Ni10 material can effectively slow down the corrosion of the intermediate shaft 11 in an acidic environment, thereby extending the service life of the intermediate shaft 11 .
