Description

Technical Field

[0001] The utility model relates to a special disassembly tool for a grinding machine clamping sleeve. Background Art

[0002] Titanium dioxide plays a very important role in polyester fiber. It can improve the breaking strength, wear resistance and UV resistance of polyester fiber materials. Titanium dioxide has high hiding and reflection properties. Some polyester products such as fibers, sheets, films, coatings, etc. require high surface brightness and whiteness. Adding an appropriate amount of titanium dioxide can effectively improve the gloss of the product surface. However, during the titanium dioxide feeding process, the titanium dioxide powder has a large particle size and is not easy to participate in the esterification reaction of polyester. The titanium dioxide powder needs to be ground to better participate in the esterification reaction of polyester. Ensuring the stable operation of the grinding machine equipment is crucial to the production of the device.

[0003] The titanium dioxide matting agent configuration system of the polyester device needs to be ground by a grinder (the grinder includes an outer cylinder and an inner cylinder arranged inside the outer cylinder) because the titanium dioxide powder is easily affected by moisture and forms lumps and the particle size of the titanium dioxide is relatively large. The qualified materials are transported to the reactor to participate in the reaction. Since the grinder is equipped with zirconium oxide balls with a diameter of 0.6 mm, the large particles of titanium dioxide are crushed under the impact and friction of a large number of high-hardness zirconium oxide balls until the production particle size is reached. Since zirconium oxide will rub the grinding cylinder surface while impacting the titanium dioxide particles, the inner cylinder of the grinder will be perforated after long-term use and needs to be inspected and replaced regularly. During the replacement process, the disassembly of the grinding cylinder is difficult and time-consuming. Utility Model Content

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0038] See also Figures 1 to 13 The special disassembly tool for the grinding machine sleeve shown in the figure, the sleeve comprises an outer cylinder 5 and an inner cylinder 8 arranged inside the outer cylinder 5, and the outer cylinder 5 and the inner cylinder 8 are arranged concentrically. The tool comprises a support member, a plug cover 7, a pull rod 9, and a driving member 2, the support member is used to support the grinding machine sleeve, the plug cover 7 is arranged at one end of the inner cylinder 8 and forms an integral body with the inner cylinder 8, and the plug cover 7 blocks one end of the inner cylinder 8; the pull rod 9 is connected to the plug cover 7, and the pull rod 9 is located inside the inner cylinder 8 and extends to the other end of the inner cylinder 8;

[0039] The tooling has a disassembled state. When in the disassembled state, the clamping sleeve is horizontally arranged, that is, the center lines of the outer cylinder 5 and the inner cylinder 8 are horizontally arranged; the driving member 2 is located outside one end of the outer cylinder 5, and the driving member 2 is used to drive the plug cover 7 to move away from the end of the outer cylinder 5. Under the pressure of the plug cover 7, the movement of the plug cover 7 drives the inner cylinder 8 to move. In addition, pulling the pull rod 9 to move away from the end of the outer cylinder 5 can further pull the inner cylinder 8. During operation, the position of the outer cylinder 5 is fixed. Through the driving member 2, the plug cover 7 and the pull rod 9, the inner cylinder 8 can be moved away from the end of the outer cylinder 5 until it is separated from the outer cylinder 5.

[0040] The inner cylinder 8 of this example includes a cylinder body 81, and the two opposite ends of the cylinder body 81 are provided with matching parts 82, and the outer diameter of the matching part 82 is smaller than the outer diameter of the cylinder body 81. The outer periphery of the matching part 82 forms a matching surface matching the inner wall of the outer cylinder 5.

[0041] See also Figure 6-7 The plug cover 7 includes a body 71 and a convex portion. The convex portion is arranged on a surface of the body 71. The convex portion has an annular side wall, that is, the convex portion is annular. The convex portion is connected to the body 71 and surrounds a storage space with an opening on one side. The pull rod 9 is connected to the side of the body 71 facing the convex portion. The cross section of the body 71 is circular. The outer diameter of the body 71 is smaller than the inner wall diameter of the outer cylinder 5. The outer diameter of the convex portion is smaller than the outer diameter of the body 71. The outer diameter of the convex portion is equal to the inner diameter of the inner cylinder 8, or the outer diameter of the convex portion is slightly smaller than the inner diameter of the inner cylinder 8. In this way, when the plug cover 7 is arranged on the inner cylinder 8, the convex portion enters the inner cylinder 8 (the outer periphery of the convex portion can abut against the inner wall of the inner cylinder 8), the body 71 is located outside the inner cylinder 8, and the body 71 can abut against the outer end surface of the matching portion 82 of the inner cylinder 8. At this time, the plug cover 7 and the inner cylinder 8 better form an integral body.

[0042] In a preferred embodiment, the outer diameter of the main body 71 is equal to the outer diameter of the matching portion 82 of the inner tube 8, so as to ensure that the plug cover 7 and the inner tube 8 can be smoothly withdrawn from the outer tube 5.

[0043] The specific implementation method of connecting the pull rod 9 to the side of the main body 71 facing the convex portion is as follows: a connecting portion 10 is provided on the side of the main body 71 facing the convex portion, a mounting hole is provided on the connecting portion 10, an internal thread (M30 threaded hole) is provided in the mounting hole, an external thread matching the internal thread is provided at one end of the pull rod 9, one end of the pull rod 9 is arranged in the mounting hole and threadedly connected to the connecting portion 10, so that the connection is firm and it is also convenient for the pull rod 9 to be separated from the plug cover 7.

[0044] See also Figure 7 The convex portion may include a first section 72 and a second section 73 connected to each other. The first section 72 is connected to both the main body 71 and the second section 73. The diameter of the first section 72 is consistent, and the diameter of the second section 73 gradually decreases from the main body 71 to the first section 72. This arrangement makes it easier for the plug cover 7 to be inserted into one end of the inner body, making the operation more convenient.

[0045] Furthermore, the tooling also includes a power piece. A pull ring 14 is provided at the other end of the pull rod 9. The power piece is connected to the pull ring 14 and is used to drive the pull rod 9 to move to the side away from the outer tube 5. The movement of the pull rod 9 drives the plug cover 7 and the inner tube 8 to move, which can drive the inner tube 8 to separate from the outer tube 5 more quickly. The power piece can be a hand winch.

[0046] The tooling also includes a fixing plate 1, which is used to be connected to the outer cylinder flange 4 and is located at one end of the outer cylinder 5. The plug cover 7 is opposite to the fixing plate 1. When in the disassembled state, one end of the driving member 2 passes through the fixing plate 1 and abuts against the plug cover 7. The fixing plate 1 is used to support the driving member 2, so that one end of the driving member 2 can pass through the fixing plate 1.

[0047] In this example, the fixing plate 1 is connected to the outer cylinder 5 by fixing bolts 3, and a plurality of fixing bolts 3 may be provided, such as Figure 1-4 The driving member 2 is a screw rod, the extension direction of the screw rod is parallel to the center line of the inner cylinder 8 (or the center line of the screw rod and the center line of the inner cylinder 8 are in the same straight line), and a threaded hole is opened on the fixing plate 1. The threaded hole passes through the opposite sides of the fixing plate 1. The screw rod is screwed and connected with the threaded hole. The screw rod can be manually tightened to make the screw rod move along its axial direction to push the plug cover 7 to move.

[0048] In some embodiments, a reinforcing rib 11 is disposed on a side of the fixing plate 1 away from the outer cylinder 5 to improve the strength of the fixing plate 1 and further provide stability for the fixing plate 1 to support the driving member 2 .

[0049] In this example, the support member includes a leg 6 and a fastener 12. The leg 6 extends in the vertical direction. A plurality of legs 6 and fasteners 12 are provided. The legs 6 and fasteners 12 correspond to each other one by one. An opening 61 is provided on the leg 6. One end of the fastener 12 passes through the opening 61 and abuts against the outer tube 5. Figure 1-4 Four legs 6 are provided, two legs 6 are located on one side of the outer tube 5, and the other two legs 6 are located on the other side of the outer tube 5, which can stably support the outer tube 5 and prevent the outer tube 5 from moving.

[0050] In some embodiments, the opening 61 is in the shape of a long strip, and the opening 61 extends in the vertical direction. The fastener can be fixed at a suitable position of the opening 61 according to the height and thickness of the outer cylinder 5, which is flexible to operate and has a strong universal shape. The lower end of the leg 6 can be provided with a moving wheel 13 to facilitate the movement of the grinding machine clamping sleeve, which saves effort and time in operation, and the moving wheel 13 can be a universal wheel.

[0051] The specific implementation method of the grinding machine sleeve special disassembly tool for disassembling the inner cylinder 8 in this example is as follows:

[0052] After the grinder sleeve is removed from the main engine, it is pushed to the maintenance area for disassembly. First, the grinder sleeve is fixed on the support, and then the plug cover 7 is installed at one end of the inner cylinder 8. The pull rod 9 is connected to the plug cover 7, and the fixing plate 1 is connected to the outer cylinder flange 4. The lifting ring of the pull rod 9 is connected to the 1-ton hand chain hoist. Then the drive member 2 is installed, and the drive member 2 moves toward the plug cover 7 until it contacts the plug cover 7. The drive member 2 continues to rotate. Under the pressure of the plug cover 7, the grinder inner cylinder 8 begins to move outward. After moving to 50mm, the matching surface of the grinder inner cylinder 8 and the external sleeve is completely disengaged. At this time, the hand chain hoist is used to pull the pull rod 9 (using the hand chain hoist at this time can prevent the inner cylinder 8 from being pulled off), and the inner cylinder 8 is slowly moved out. After the inner cylinder 8 is removed, it is cleaned, and then the new inner cylinder 8 is placed in the original outer cylinder 5. Finally, the grinder sleeve is installed on the main engine, and the grinder is restored and the test run begins.

[0053] The advantages of the special disassembly tool for the grinding machine sleeve in this example are:

[0054] 1. The inner cylinder can be taken out quickly and conveniently, saving time and effort without damaging the inner cylinder, solving the problem of high difficulty in replacing the inner cylinder of the titanium dioxide grinder of the polyester device;

[0055] 2. Effectively reduce the maintenance hours of the grinder, effectively improve the maintenance efficiency of the grinder, ensure the quality of equipment maintenance, and reduce the workload of maintenance personnel.

[0056] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
