Description

Technical Field

[0001] This utility model relates to the field of padding equipment technology, and in particular to a padding sleeve for a three-roll mill and its mounting device. Background Technology

[0002] Three-roll mills, also known as three-roll grinding mills, are mainly used in the manufacture of various paints, inks, pigments, and other pastes. They thoroughly mix solid and liquid materials in raw materials and are particularly suitable for grinding and dispersing products with high viscosity and fine particle size requirements. The grinding effect is achieved through the mutual extrusion and friction at different speeds of the surfaces of three horizontal rollers.

[0003] After installation, the traditional roller is in a fixed position. After long-term use, the two ends of the roller will wear out severely, causing axial movement and impact on the edge when the roller rotates. This increases the noise of the device and affects the rolling effect. The traditional method is to remove the roller and then install a shim on the roller's rotating shaft to fix the roller's position.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a three-roll mill pad and its mounting device. This device can install pads on both ends of the roller without disassembling the roller, ensuring that the roller is protected by the installed pads, reducing wear and noise caused by roller impact, and reducing the workload caused by disassembling the roller.

[0006] To achieve the above objectives, this utility model provides a three-roll mill pad and its mounting device, comprising: two opposing mounting heads, a pressing member slidably provided on the outer side wall of the mounting head, the pressing member including a pressing part penetrating the side wall of the mounting head and an arc-shaped part fixed to one end of the pressing part located inside the mounting head, the pad abutting against the inner wall of the arc-shaped part and being fastened to the rotating shaft of the transmission device under the action of the mounting head.

[0007] In one embodiment, the transmission device includes three grinding rollers, which are rotatably connected to the main frame. The grinding rollers are rotatably connected to the main frame via a rotating sleeve.

[0008] In one embodiment, the end of the grinding roller is provided with a limiting protrusion corresponding to the rotating sleeve, and the pad abuts between the rotating sleeve and the grinding roller.

[0009] In one embodiment, a drive motor is fixedly mounted on one side of the main frame, and the drive motor drives the three grinding rollers to rotate. The grinding rollers are provided with rotating shafts at both ends, and the rotating shafts are inserted into the rotating sleeve.

[0010] This utility model also provides a pad sleeve, including two opposing semicircular pads, each of the two semicircular pads including two symmetrically arranged semicircular rings, a thrust spring between the two semicircular rings of the same semicircular pad, and the outer walls of the two semicircular rings closely abutting the limiting protrusion and the inner wall of the rotating sleeve.

[0011] In one embodiment, the end of the semicircular ring is provided with a snap-fit ​​protrusion and a snap-fit ​​groove. During installation, the snap-fit ​​protrusions of the two semicircular pads engaging with each other are snapped into the corresponding snap-fit ​​grooves. The edge of the snap-fit ​​portion is provided with a guide bevel.

[0012] In summary, the technical effects achieved by this utility model are:

[0013] 1. A cushioning pad structure is set at both ends of the grinding roller to ensure that the impact force at both ends of the grinding roller can be buffered during use, thereby reducing the impact of the grinding roller on the main frame during use, reducing the noise generated by the impact, and reducing the wear of the grinding roller during the impact.

[0014] 2. By setting up an assembly-type pad structure and an installation head for assembling the pad, it is possible to assemble the two semi-circular pads. This allows for the addition of a pad without disassembling the grinding roller, thereby reducing the disassembly and maintenance costs of the grinding roller. Attached Figure Description

[0026] See Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7This utility model provides a pad for a three-roll mill and its mounting device, including: two opposing mounting heads 6, which ensure that the pad 3 can be mounted opposite each other on the rotating shaft. The outer side wall of the mounting head 6 is slidably provided with a pressing member 7, which presses two semi-circular pads inside onto the rotating shaft. At the same time, the two semi-circular pads are interlocked, thereby assembling the semi-circular pads to form the pad 3, which is then installed onto the transmission device to complete the installation and fixation of the pad 3. The pressing member 7 includes a pressing part 71 that penetrates the side wall of the mounting head 6 and an arc-shaped part 72 fixed to one end of the pressing part 71 inside the mounting head 6. The pad 3 abuts against the inner wall of the arc-shaped part 72 and, under the action of the mounting head 6, fastens the pad 3 onto the rotating shaft of the transmission device, thereby realizing the assembly and installation of the pad 3 itself.

[0027] Among them, see Figure 6 and Figure 7 To ensure the proper assembly and use of the mounting head 6 and the pressing part 7, a sliding hole 61 is provided on the side wall of the mounting head 6. The pressing part 71 on the pressing part 7 is slidably connected to the inside of the sliding hole 61. At the same time, a return spring is provided between the sliding hole 61 and the pressing part 71. The pressing part 71 is moved to the outside of the mounting head 6 by the return spring, thereby ensuring the reset of the pressing part 7. Meanwhile, the arc-shaped part 72 acts on the pad 3, which facilitates the action of the arc-shaped part 72 on the pad 3, thereby facilitating the pressing action of the pad 3.

[0028] In the three-roll grinding machine of this utility model, a transmission device is provided on its main frame 1. In order to ensure the normal transmission of the three grinding rollers 4, the grinding rollers 4 are driven to rotate by the drive motor 5. At the same time, a transmission gear can be set on the rotating shaft of the grinding rollers 4 to ensure the normal rotation of the grinding rollers 4. In order to ensure the use of the grinding rollers 4, the transmission can be adapted to belt, chain or other transmission methods.

[0029] In one exemplary embodiment, the transmission device includes three grinding rollers 4, which are rotatably connected to the main frame 1. The grinding rollers 4 are rotatably connected to the main frame 1 via a rotating sleeve 2. The rotating sleeve 2 is provided with a socket 12, and the rotating shaft of the grinding roller 4 is inserted into the socket 12. To ensure that the rotating sleeve 2 and the grinding roller 4 rotate synchronously, the socket 12 and the rotating shaft can be connected by a spline, or the socket 12 and the rotating shaft can be directly set to an interference fit. Then, a transmission gear, belt, or chain transmission structure is provided on the rotating sleeve 2.

[0030] In one exemplary embodiment of this invention, the end of the grinding roller 4 is provided with a limiting protrusion corresponding to the rotating sleeve 2, the inner side of the rotating sleeve 2 is provided with a limiting ring 11, and the pad 3 abuts between the rotating sleeve 2 and the grinding roller 4. By inserting the pad 3 into the limiting ring 11 and the limiting protrusion, the wear resistance and internal impact strength of the rotating sleeve 2 and the grinding roller 4 are increased, preventing damage to the main body of the rotating sleeve 2 and the grinding roller 4 and affecting the use of the equipment.

[0031] In use, the two parts of the pad 3 are placed between the two abutment rings 62 of the mounting head 6, with the inner diameter of the abutment ring 62 corresponding to the diameter of the rotating shaft. Then, the two mounting heads 6 are directly connected to one end of the grinding roller 4 where the pad 3 needs to be installed. At this time, under the action of the abutment ring 62, the pad 3 abuts against the limiting protrusion and the outer wall of the limiting ring 11, and then the pad 3 is snapped and fixed.

[0032] Furthermore, in combination Figure 3 and Figure 4 The present invention also provides a pad sleeve 3, which includes two opposing semicircular pads. Each semicircular pad includes two symmetrically arranged semicircular rings 31. A thrust spring 34 is provided between the two semicircular rings 31 of the same semicircular pad. The outer walls of the two semicircular rings 31 are in close contact with the limiting protrusion and the inner wall of the rotating sleeve 2.

[0033] In one embodiment, the end of the semicircular ring 31 is provided with a snap-fit ​​protrusion 32 and a snap-fit ​​groove. During installation, the snap-fit ​​protrusion 32 of the mating part of the two semicircular pads snaps into the corresponding snap-fit ​​groove. The edge of the snap-fit ​​part is provided with a guide bevel 33. The guide bevel 33 facilitates the snap-fit ​​of the semicircular rings 31 to each other during the assembly of the pad sleeve 3, thereby assembling the two semicircular pads to form a circular pad sleeve 3. At the same time, under the thrust of the thrust spring 34, the semicircular ring 31 is self-locked, thereby fixing the pad sleeve 3 itself.

[0034] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
