Technical field

The present invention relates to the technical field of strip processing, and in particular to a roll changing mechanism used in the strip surface pretreatment process.

Background technique

In the process of strip steel production or post-surface treatment, the surface needs to be polished to ensure its smoothness. The surface of the grinding roller used to polish the strip steel surface on the existing grinding machine will become smooth after long-term use. , which is not conducive to subsequent grinding operations. If the existing roller changing mechanism adopts a fully automated design, it will have high requirements on process and precision, which will greatly increase the cost; and if it relies entirely on manual labor, replacing the grinding roller will be time-consuming and laborious. Therefore, A roll changing mechanism for strip surface treatment is proposed. This roll changing mechanism can assist operators in changing rolls, which not only reduces processing costs, but also simplifies the roll changing operation.

An arc-shaped block is movably installed on the second arc-shaped block. 1. The arc-shaped block one and the output end of the hydraulic rod are fixedly connected together, and the grinding roller is rotatably installed between the arc-shaped block one and the arc-shaped block two.

The rod seat of the hydraulic rod is fixed on the side wall of the support shaft seat through screws or welding. The fixed sleeve is divided into a fixed part and a movable part, making the separation and closing operations simple and can be completed by telescopically extending the hydraulic rod.

During grinding, the strip steel moves along the guide rollers. Multiple sets of grinding components polish the surface of the strip steel. When the grinding roller is seriously worn and needs to be replaced, the support shaft seat rotates to the roller replacement position. , the grinding roller is removed from the support shaft seat to the old roller bearing seat, and the new grinding roller on the new roller bearing seat is transferred to the support bearing seat.

Different from the traditional roller-changing structure for surface polishing of strip steel, this invention can semi-automatically replace seriously worn grinding rollers, reducing the time for workers to install and disassemble the grinding rollers, and ensuring that the grinding rollers in contact with the strip steel always have excellent polishing effects. It saves time and effort while also improving production efficiency.

The distance between the second rotating column 42 and the third rotating column 43 is greater than the diameter of the grinding roller 37. The bottom end of the second mounting frame 41 is fixedly installed with Two vertical poles 46 are fixedly connected to the frame 50; a plurality of supporting plates 44 arranged perpendicularly to the rotating column 42 are fixedly installed, and the rotating column 42 and the supporting plate 44 form a new structure. The roller bearing seat; a plurality of supporting plates 45 perpendicular to the rotating column 3 43 are fixedly installed, and the rotating pillar 43 and the supporting plate 2 45 together form the old roller bearing seat; the supporting plate 1 44 and the supporting plate 2 Limiting plates that prevent the grinding roller 37 from rolling off are fixedly installed on both sides of the top of the 45.

To further explain, as shown in Figure 2, the grinding assembly 3 includes a pair of support shaft seats 33 movably connected with the frame 50. The support shaft seats 33 are provided with mounting grooves 34, and the grinding roller 37 is placed in the mounting grooves. 34, a hydraulic rod 35 and a fixed sleeve 36 are also fixedly installed on the support shaft seat 33. As shown in Figure 5, the fixed sleeve 36 includes a second arc block 362, a first arc block 361, a second arc block 362 and a support shaft seat. 33 is fixedly connected, the arc block one 361 is fixedly connected to the output end of the hydraulic rod 35, the arc block one 361 is symmetrically provided with two guide holes 363, the side of the arc block two 362 close to the arc block one 361 is fixed correspondingly Two guide rods 364 are installed, the arc block two 362 and the arc block one 361 are axially connected through the guide hole 363 and the guide rod 364, and the grinding roller 37 is rotatably installed between the arc block one 361 and the arc block two 362. inside the circular hole.

To further explain, as shown in Figure 2, the grinding assembly 3 also includes two mounting brackets 31 fixedly connected to the frame 50.

To further explain, during the implementation of the grinding work, the strip steel enters the grinding chamber 1 downward along the upper surface of the frame and is pressed tightly by the grinding roller 37 to form tension and deformation. At this time, the tension and deformation on the strip 6 The rust and oxide scale on the surface of the strip 6 are caused to fall off or loosen due to fission, and then the grinding roller 37 further polishes the surface of the strip 6 . For the processed debris, a blower can be installed next to the grinding roller 37 to blow it off.

To further explain, when the grinding roller 37 deteriorates in grinding quality due to wear and needs to be replaced, the main machine is shut down to stop the movement of the strip; first, the second motor 410 drives the hinge block 48 to rotate counterclockwise, limited by the waist-shaped hole in the hinge block 48 length, the hinge block 48 can only rotate at a certain angle. The hinge rod 47 connected to the hinge block 48 drives the rotating column 2 42 and the rotating column 3 43 to rotate counterclockwise at a certain angle at the same time. The supporting plate 1 44 and the supporting plate 2 45 also follow. Tilt counterclockwise, the new grinding roller 37 to be replaced is stored on the supporting plate 44, and the limiting plate restricts the grinding roller 37 on the supporting plate 1 44 and the supporting plate 2 45 from falling into the grinding chamber 1; and then through the motor 1 38. Rotate the rotating column 32 clockwise to the top of the supporting plate 2 45 and then retract the hydraulic rod 35. The grinding roller 37 will fall onto the supporting plate 2 45 along the gap of the installation groove due to its own gravity; at this time, the worker can use the new grinding roller to 37 in size, place the new grinding roller 37 in the installation groove by driving or manpower. After the hydraulic rod 35 extends forward to compress the shaft of the grinding roller 37, the motor 38 rotates to rotate the rotating column 32 counterclockwise to the grinding position, and starts the main machine. The strip movement begins the grinding work.
