Technical Field

[0001] The utility model relates to the field of granulator maintenance equipment, in particular to a device for disassembling a pressure roller and a spacer ring of a granulator in a feed factory. Background Art

[0002] The pressing roller is a component of the granulator. The granulator makes granules by squeezing the pressing roller and the ring film in the granulator against each other to complete the granulation.

[0003] The pressure roller is a key force-bearing component and bears enormous pressure during operation. Therefore, a roller spacer is installed on the inner wall of the pressure roller, and the roller spacer is installed with an interference fit with the pressure roller. Since the roller sleeve is in contact with hard materials and wears for a long time, it needs to be replaced and repaired regularly to ensure the grinding efficiency of the high-pressure roller mill. When replacing and repairing, the spacer ring on the inner side of the roller sleeve of the pressure roller needs to be removed, and then the spacer ring and the new roller sleeve are reassembled by interference fit. At the same time, it is necessary to ensure that the spacer ring is not damaged during the disassembly process.

[0004] In the past, the spacer rings were removed manually, that is, a hammer was used to knock the spacer rings out from the inner wall of the pressure roller, which easily damaged the pressure roller and the spacer rings and made removal difficult. When removing the pressure roller spacer rings, the manual method was time-consuming and labor-intensive, requiring multiple workers to work together, and the operators were easily injured.

[0005] In view of the above, it is necessary to propose a feed mill pellet mill roller spacer ring disassembly device to solve the above problems. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a feed factory pelletizing machine pressure roller spacer ring disassembly device, comprising a frame, a bottom plate, an upper plate, and a lower plate, wherein the bottom plate is arranged at the lower end of the frame, the lower plate is arranged in the middle of the frame, the upper plate is arranged on the upper side of the lower plate, a jack is arranged on the bottom plate, a top plate is arranged on the jack, the diameter of the top plate matches the inner diameter of the pressure roller of the spacer ring, there is an accommodating space between the lower plate and the upper plate, and U-shaped openings are arranged on the lower plate and the upper plate, and when the top plate is lifted by the jack, it passes through the U-shaped opening of the lower plate, and the spacer ring is ejected through the U-shaped opening of the upper plate.

[0008] Furthermore, the U-shaped opening of the lower plate is coaxially arranged with the arc inner bottom of the U-shaped opening of the long plate, and is coaxially arranged with the lifting axis of the jack.

[0009] Furthermore, a loading platform is laterally extended on one side of the U-shaped opening of the lower plate, guide rails are provided on both sides of the U-shaped opening of the lower plate, a translation plate is slidably connected to the guide rails, and a through hole is provided on the translation plate.

[0010] Furthermore, a step edge is formed on the inner wall of the through hole, and an annular plate is built in the step edge. The inner diameter of the annular plate is larger than the inner diameter of the pressure roller and smaller than the outer diameter of the pressure roller.

[0011] Furthermore, a stopper is provided on the lower plate, and the stopper is located outside the bottom side of the arc of the U-shaped opening. The stopper limits the translation plate so that the through hole is coaxial with the jack.

[0012] Furthermore, the top plate is disc-shaped, and a positioning groove is provided on the lower end surface of the top plate. The positioning groove is located at the center of the top plate, and the shape of the positioning groove matches the upper top rod end of the jack.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] A device for disassembling the roller spacer ring of a pellet mill in a feed factory, such as Figure 1-3 As shown, it comprises a frame 1, a bottom plate 2, an upper plate 3, and a lower plate 4. The bottom plate 2 is arranged at the lower end of the frame 1. As shown in the figure, the enclosure can be formed by using the columns shown in the figure. The four corners of the bottom plate 2 are provided with columns to form the frame 1. The middle part of the frame 1 is provided with a lower plate 4, and the upper side of the lower plate 4 is provided with an upper plate 3. A jack 5 is arranged on the bottom plate 2, and a top plate 6 is arranged on the jack 5. The jack 5 is used as a pushing power to push the spacer ring 20 on the inner wall of the pressure roller 19 upward. The diameter of the top plate 6 matches the inner diameter of the pressure roller 19 of the spacer ring 20. The lower plate 4, There is an accommodating space 7 between the upper plates 3. When in use, the pressure roller 19 to be disassembled is placed in the accommodating space 7 and placed in a vertical direction along its axis. The lower plate 4 and the upper plate 3 are both provided with a U-shaped opening 8, and the opening side can be used for the pressure roller 19 to be easily placed in or taken out. During actual use, the top rod end of the upper part of the jack 5 is controlled to move upward to push the top plate 6 to rise. When the top plate 6 is lifted by the jack 5, it passes through the U-shaped opening 8 of the lower plate 4, and then the spacer ring 20 is ejected through the U-shaped opening 8 of the upper plate 3. After being ejected, it can be moved out from the side through the U-shaped opening 8.

[0022] Furthermore, the U-shaped opening 8 of the lower plate 4 is coaxially arranged with the arc inner bottom of the U-shaped opening 8 of the long plate, and is coaxially arranged with the lifting axis of the jack 5. In order to improve the accuracy of jacking, the coaxial arrangement is maintained in the vertical direction, which can improve the accuracy of jacking.

[0023] like Figure 1 , 2 As shown, a loading platform 9 is extended laterally on the side of the U-shaped opening 8 of the lower plate 4, and the length of the laterally extended side of the lower plate 4 is greater than that of the upper plate 3, so that the laterally extended part forms the loading platform 9, as shown in FIG. Figure 1 As shown, when the pressure roller 19 is placed, it can be placed on the loading platform 9 first, and then moved horizontally into the accommodating space 7. Conversely, when the removal is completed, it can be moved out horizontally, which is convenient to use. Specifically, as shown in FIG. Figure 2 As described, guide rails 10 are provided on both sides of the U-shaped opening 8 of the lower plate 4, and a translation plate 11 is slidably connected to the guide rails 10, and a through hole 12 is provided on the translation plate 11. It can be understood that when the jack 5 pushes, the lower plate 4 is not subjected to the thrust, but the thrust is applied to the upper plate 3, so the loading platform 9 does not bear the force when pushing, so the convenient movement mode of the track can be adopted.

[0024] Since the pressure roller 19 has various types and diameters, the through hole 12 on the translation plate 11 is designed to be adaptable to various types of structures, specifically, Figure 2 As shown, a step edge 13 is formed on the inner wall of the through hole 12, and an annular plate 14 is built in the step edge 13. The inner diameter of the annular plate 14 is larger than the inner diameter of the pressure roller 19 and smaller than the outer diameter of the pressure roller 19; the annular plate 14 is used to directly support the pressure roller 19, and the inner diameter of the annular plate 14 needs to allow the top plate 6 to pass through. The annular plate 14 is designed to be supported by the step edge 13 and can be disassembled and replaced, so that annular plates 14 of various inner diameter models can be prepared to accommodate the disassembly of various models of pressure rollers 19.

[0025] Furthermore, a stopper 15 is provided on the lower plate 4, and the stopper 15 is located outside the bottom side of the arc of the U-shaped opening 8. The stopper 15 limits the translation plate 11 so that the through hole 12 is coaxial with the jack 5. Since the translation plate 11 reciprocates on the wire track, the same axis position is required when the pressure roller 19 is sent into the accommodating space 7, so the stopper 15 is provided, that is, when the translation plate 11 moves inward and is stuck in the position of the stopper 15, the coaxiality can be ensured.

[0026] Furthermore, the top plate 6 is in a disc shape, and a positioning groove 16 is provided on the lower end surface of the top plate 6. The positioning groove 16 is located at the center of the top plate 6, and the shape of the positioning groove 16 matches the upper push rod end of the jack 5. Figure 3 As shown, the outer diameter of the top plate 6 can be replaced according to the inner diameter of the disassembled pressure roller 19, so that multiple diameter models can be processed and selected according to the inner diameter of the pressure roller 19. When installing, the positioning groove 16 is inserted into the end of the push rod to keep the center of the circle aligned. Further, the top plate 6 includes a reducing disk 17 and an expanding ring 18. The expanding ring 18 is provided on the outer edge of the upper end of the reducing disk 17. The outer diameter of the expanding ring 18 is greater than the outer diameter of the reducing disk 17, so that the top plate 6 forms a trumpet-shaped structure that opens upward. In order to reduce the friction resistance formed between the top plate 6 and the inner wall of the pressure roller 19 during the upward pushing process, a trumpet-shaped structure with a large upper opening and a small lower opening is provided. The expanding ring 18 can be used to contact the lower end of the spacer ring 20, while the narrowed side wall of the reducing disk 17 does not contact the inner wall of the pressure roller 19, thereby effectively reducing the friction resistance. Further, the height position of the upper plate 3 relative to the surrounding frame 1 is adjustable; its height adjustment is convenient for adapting to the processing of pressure rollers 19 of different lengths, thereby improving the scope of application of the device.
