Among them, the four-roller plate rolling machine is suitable for bending and forming metal sheets. It has the function of pre-bending the ends of the plates, with small remaining straight edges and high work efficiency. The metal sheets can also be roughly leveled on this machine. Its working principle is that the upper roller is fixed in position, the lower roller moves upward in a straight line to clamp the steel plate, and the rollers on both sides move in a straight line or arc toward the upper roller to adjust the curvature radius of the roller.
[0003] During the use of the existing four-roller plate rolling machine, the rollers will wear out due to the long-term interaction with the metal plates. The two ends of the rollers are usually connected to the machine base with bearings. Therefore, the entire structure needs to be removed during disassembly before the rollers can be replaced and maintained. The operation is cumbersome and inconvenient, which greatly affects work efficiency. In addition, generally speaking, the rollers are heavy, and sometimes the rollers need to be moved during disassembly, which makes the disassembly work more troublesome. For this reason, we propose a four-roller plate rolling machine that is easy to replace the rollers to solve the above problems. Utility Model Content

[0021] See also Figure 1-4 The utility model provides an embodiment of a four-roller plate rolling machine which is convenient for replacing the rolling rollers, comprising a four-roller plate rolling machine body 1, a mounting round block 2 is installed on the four-roller plate rolling machine body 1, a rolling roller body 3 is provided on the mounting round block 2, a square block 4 is fixedly installed on the mounting round block 2, a square groove 5 is opened at one end of the rolling roller body 3, the square block 4 is inserted in the square groove 5, a limiting rod 8 is movably provided in the square block 4, a limiting hole 9 is opened on the rolling roller body 3, the limiting rod 8 is inserted in the limiting hole 9, and a limiting mechanism is provided on the square block 4. This equipment realizes the mutual assembly between the mounting round block 2 and the rolling roller body 3 by means of shape engagement. Such an installation method is more stable and more convenient to disassemble.
[0022] Furthermore, the limiting mechanism includes a first movable groove 6, a first movable groove 6 is opened in the square block 4, and a second movable groove 7 is opened in the mounting circular block 2. The first movable groove 6 is connected to the second movable groove 7, and the limiting rod 8 moves in the first movable groove 6. The lower end of the limiting rod 8 is fixedly installed with a movable plate 10, and two groups of screws 11 are provided on the movable plate 10. Two groups of screw sleeves 12 are provided at the second movable groove 7. The screw 11 is fixedly installed in the screw sleeve 12. This structure enables, on the basis of the square block 4 being inserted into the square groove 5, the limiting rod 8 is inserted into the limiting hole 9, thereby realizing complete locking between the roller body 3 and the mounting circular block 2, increasing the stability of the equipment during use, and the screw 11 is not directly connected to the mounting circular block 2 and the roller body 3, so the force applied to the screw 11 during operation will be smaller than the force applied by the direct fixing force, thereby making the equipment more stable when in use.
[0023] Furthermore, a limiting groove 13 is provided on one side of the second movable groove 7. The shape and size of the limiting groove 13 are adapted to the shape and size of the movable plate 10. A finger groove 14 is provided on the lower side of the movable plate 10. This structure allows the movable plate 10 to be engaged in the limiting groove 13, and there will be no misalignment when the screw 11 needs to be installed. At the same time, it also reduces the lateral force on the screw 11, because the lateral force will be borne by the mutual compression between the movable plate 10 and the limiting groove 13.
[0024] Furthermore, a guide rod 15 is fixedly installed in the first movable groove 6, and a guide groove 16 is provided on the limit rod 8. The guide rod 15 slides in the guide groove 16. The length of the guide rod 15 is greater than the width of the second movable groove 7. This structure makes the limit rod 8 more stable when subjected to force, thereby increasing the stability of the equipment when in use.
[0025] Furthermore, the right side of the mounting round block 2 and the left end of the roller body 3 can form a circle, and the width of the limiting rod 8 is smaller than the width of the square block 4. This structure allows the roller body 3 to fall naturally when it is disassembled, increasing the convenience of disassembling the equipment.
[0026] Furthermore, the upper sides of the three groups of roller bodies 3 on the lower side are all provided with a card slot 17, and a circular hole 18 is opened in the card slot 17. A receiving plate 19 is placed on the card slot 17, and a limiting circular block 20 is fixedly installed in the lower array of the receiving plate 19. The limiting circular block 20 is placed in the circular hole 18. This structure allows the receiving plate 19 to assist in the disassembly of the roller body 3 on the lower side, and the receiving plate 19 can play the role of supporting the roller body 3, thereby increasing the convenience of using the equipment.
[0027] Furthermore, the size of the square block 4 is adapted to that of the square groove 5, and limiting holes 9 are provided at the left end of the roller body 3 and the left end of the mounting circular block 2. This structure makes the connection between the roller body 3 and the mounting circular block 2 more stable.
[0028] Furthermore, the width of the second movable groove 7 is greater than the length of the screw 11, and the lower side of the movable plate 10 is adapted to the shape of the lower side of the mounting block 2. This structure ensures that the disassembly of the screw 11 will not be blocked by the second movable groove 7, while making the device more beautiful.
[0029] Working principle: When disassembling the roller body 3, rotate the left end of the roller body 3 to the lower side, then unscrew the screw 11, and move the movable plate 10 through the finger groove 14. At this time, the limit rod 8 disengages from the limit hole 9, so that the installation round block 2 and the roller body 3 are not locked by the vertical force, thereby realizing the disassembly of the roller body 3. At this time, the square block 4 automatically falls off from the square groove 5. When the lower three groups of roller bodies 3 are disassembled, they can be assisted by the receiving plate 19 for receiving and moving. The receiving plate 19 is engaged in the card groove 17, and the limiting round block 20 is inserted in the round hole 18. The roller body 3 can be dragged at the same time. The installation is similar. When the equipment is working, the motor used to install the round block 2 is connected to the inside of the four-roller plate rolling machine body 1, so it can drive the roller body 3 to rotate. The above is the entire working principle of the present utility model.
[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
