Description

Technical Field

[0001] This utility model relates to the field of empty shaft technology for granulators, specifically a disassembly device for empty shafts of granulators. Background Technology

[0002] As core equipment in industries such as pharmaceuticals, chemicals, and food, granulators rely heavily on their hollow shafts as crucial fundamental components, playing an irreplaceable role in equipment operation. On one hand, the hollow shaft provides stable support for transmission components (such as pressure rollers and drums), ensuring precise axial positioning and stable operation during high-speed rotation. On the other hand, through coordinated operation with the tensioning mechanism, it precisely adjusts the tension of the transmission belt and chain, guaranteeing efficient and stable power transmission—a vital guarantee for maintaining continuous and reliable equipment operation.

[0003] As the pellet mill operates under high load for extended periods, the empty shaft is prone to wear, deformation, or bearing damage due to factors such as mechanical friction, material corrosion, and fatigue stress. To ensure pelleting accuracy and equipment stability, the empty shaft needs to be replaced and maintained regularly. Utility Model Content

[0004] The purpose of this invention is to provide a disassembly device for the empty shaft of a pellet mill, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disassembly device for a hollow shaft of a pellet mill, comprising a hollow shaft, a long rod, and a protective shell, wherein there are two protective shells, an assembly mechanism is provided on the hollow shaft and the long rod, and a protective mechanism is provided on the hollow shaft and the long rod, wherein the protective mechanism is located outside the assembly mechanism;

[0006] The assembly mechanism includes a plug-in component and a fixing component, wherein the fixing component is disposed on the plug-in component;

[0007] The plug-in assembly includes a circular slot, which is formed at the top of the hollow shaft. The top of the circular slot is set as an opening. The surface of the long rod is inserted into the inside of the circular slot. Slide plates are fixedly connected to the lower surface of the long rod around its perimeter. A sliding groove is formed around the inner wall of the circular slot. A connecting ring is fixedly connected to the upper surface of the hollow shaft. Long plates are fixedly connected to the top perimeter of the connecting ring. Inclined plates are fixedly connected to both sides of the long plates and the top of the connecting ring. Fixing seats are fixedly connected to the perimeter of the long rod. The fixing seats are located at the top of the slide plates. A rectangular slot is formed inside the fixing seats.

A square plate is inserted into the square groove. Fixing rods are fixedly connected to both sides of the long plate. A rotating plate is rotatably connected to the surface of the fixing rods. A square groove is formed inside the square plate on the side away from the long rod. Nuts are fixedly connected to both sides of the square plate. A screw is threadedly connected to the nuts and the rotating plate.

[0011] Preferably, the square plate has a through hole inside, and the screw is inserted through the through hole inside the square plate.

[0012] Preferably, the square groove is open on the side away from the long rod, at the top and bottom. The surface of the rotating plate is inserted into the inside of the square groove. When the square plate is inserted into the square groove, the rotating plate is inserted into the square groove, which can assemble and fix the hollow shaft and the long rod. Conversely, it is also convenient to disassemble, maintain and replace the hollow shaft regularly.

[0013] Preferably, the protective mechanism includes a T-slot, which is formed at the top and bottom of the protective shell. Limiting plates are fixedly connected to both ends of the outer surfaces of the two protective shells.

[0014] Compared with the prior art, this utility model provides a disassembly device for the hollow shaft of a pellet mill, which has the following beneficial effects:

[0015] 1. This disassembly device for the empty shaft of a pellet mill, through an assembly mechanism, allows the long rod to be inserted into the round hole groove, while simultaneously driving the sliding plate to slide into the groove. At the same time, the long plate can also be inserted into the rectangular groove. When the square plate is inserted into the square groove again, the rotating plate is rotated on the surface of the fixed rod, so that the rotating plate is inserted into the square groove. The screw thread is inserted into the nut, which can assemble and fix the empty shaft and the long rod. Conversely, the empty shaft can also be disassembled, maintained and replaced regularly.

[0016] 2. This disassembly device for the empty shaft of the pellet mill uses a protective mechanism. The electric push rod moves the clamping ring, and the clamping ring moves the T-shaped block in the T-slot until the upper and lower clamping rings clamp and fix the surface of the empty shaft and the long rod respectively. This makes it easy to set up the assembly mechanism in the space formed by the two protective shells. It can protect the assembly mechanism and prevent the screw from being arbitrarily removed from the nut. Attached Figure Description

[0031] Example 1

[0032] Combination Figures 1 to 7 A disassembly device for a hollow shaft of a pellet mill includes a hollow shaft 1, a long rod 3 and a protective shell 5. There are two protective shells 5. An assembly mechanism 4 is provided on the hollow shaft 1 and the long rod 3. A protective mechanism 2 is provided on the hollow shaft 1 and the long rod 3. The protective mechanism 2 is located outside the assembly mechanism 4.

[0033] Assembly mechanism 4 includes a plug-in component 41 and a fixing component 42, with the fixing component 42 disposed on the plug-in component 41;

[0034] The plug-in assembly 41 includes a circular slot 418, which is opened at the top of the hollow shaft 1. The top of the circular slot 418 is set as an opening. The surface of the long rod 3 is plugged into the inside of the circular slot 418. Slide plates 415 are fixedly connected to the lower surface of the long rod 3. Slide grooves 414 are opened around the inner wall of the circular slot 418. A connecting ring 411 is fixedly connected to the upper surface of the hollow shaft 1. Long plates 412 are fixedly connected to the top of the connecting ring 411. Inclined plates 413 are fixedly connected to both sides of the long plate 412 and the top of the connecting ring 411. Fixing seats 416 are fixedly connected to the surface of the long rod 3. The fixing seats 416 are set on the top of the slide plates 415. A rectangular slot 417 is opened inside the fixing seats 416.

[0035] There are four slides 414 and four slide plates 415. The surface of the slide plate 415 is slidably connected to the inside of the slide 414. The rectangular groove 417 is set to be open on the side away from the long rod 3, at the top and bottom. The surface of the long plate 412 is inserted into the inside of the rectangular groove 417.

[0036] The fixing component 42 includes a square groove 426, which is opened inside the long plate 412. The square groove 426 has openings on both sides. A square plate 427 is inserted into the square groove 426. Fixing rods 421 are fixedly connected to both sides of the long plate 412. A rotating plate 425 is rotatably connected to the surface of the fixing rods 421. A square groove 424 is opened inside the side of the square plate 427 away from the long rod 3. Nuts 423 are fixedly connected to both sides of the square plate 427. A screw 422 is threadedly connected inside the nuts 423 and the rotating plate 425.

[0037] The square plate 427 has a through hole inside, and the screw 422 is inserted through the through hole inside the square plate 427. The square groove 424 is set to be open on the side away from the long rod 3, at the top and bottom. The rotating plate 425 is inserted into the square groove 424.

[0038] Furthermore, when the long rod 3 is inserted into the round hole slot 418, the long rod 3 can also drive the slide plate 415 to slide into the slide groove 414. At the same time, the long plate 412 can also be inserted into the rectangular slot 417. When the square plate 427 is inserted into the square slot 426, the rotating plate 425 is rotated on the surface of the fixed rod 421, so that the rotating plate 425 is inserted into the square slot 424. The hollow shaft 1 and the long rod 3 can be assembled and fixed. Conversely, it is also convenient to disassemble, maintain and replace the hollow shaft 1 regularly.

[0039] Example 2

[0040] See Figure 1-9 Furthermore, based on Embodiment 1, the protective mechanism 2 further includes a T-slot 22, which is formed at the top and bottom of the protective housing 5. Limiting plates 23 are fixedly connected to both ends of the outer surfaces of the two protective housings 5 ​​respectively. Electric push rods 24 are fixedly connected to the inner sides of the left and right limiting plates 23. A clamping ring 25 is fixedly connected to the other side of the electric push rod 24. A T-block 21 is fixedly connected to the side of the clamping ring 25 near the protective housing 5. The surface of the T-block 21 and the inside of the T-slot 22 are slidably connected.

[0041] Furthermore, the electric push rod 24 drives the clamping ring 25 to move, and the clamping ring 25 drives the T-block 21 to slide in the T-slot 22 until the upper and lower clamping rings 25 clamp and fix the surfaces of the hollow shaft 1 and the long rod 3 respectively, so that the assembly mechanism 4 can be set up in the space formed by the two protective shells 5. This can protect the assembly mechanism 4 and prevent the screw 422 from being arbitrarily removed from the nut 423.

[0042] In actual operation, when this device is used, when the long rod 3 is inserted into the round hole slot 418, the long rod 3 can also drive the slide plate 415 to slide into the slide groove 414. At the same time, the long plate 412 can also be inserted into the rectangular slot 417. When the square plate 427 is inserted into the square slot 426, the rotating plate 425 is rotated on the surface of the fixed rod 421, so that the rotating plate 425 is inserted into the square slot 424. The screw 422 is threaded into the nut 423, and the empty shaft 1 and the long rod 3 can be assembled and fixed. Conversely, it is also convenient to disassemble, maintain and replace the empty shaft 1 regularly.

[0043] When the two protective shells 5 are placed on the surface of the assembly mechanism 4, the clamping ring 25 moves under the operation of the electric push rod 24. At the same time, the clamping ring 25 drives the T-block 21 to slide in the T-slot 22 until the upper and lower clamping rings 25 clamp and fix the surfaces of the hollow shaft 1 and the long rod 3 respectively. This makes it easy to place the assembly mechanism 4 in the space formed by the two protective shells 5. This can protect the assembly mechanism 4 and also prevent the screw 422 from being arbitrarily removed from the nut 423. In the composite transmission mechanism, the hollow shaft 1 is sleeved on the outside of the long rod 3 and passively follows the rotation of the long rod 3 through transmission elements such as gears and belts to realize the transmission and distribution of power.
