Description

Technical Field

[0001] This utility model relates to a tooling for disassembling a melt filter nut. Background Technology

[0002] During the melt conveying process in a polyester unit, a melt filter is used to filter agglomerated particles in the melt. The melt filter includes a housing and a filter element. The filter element is located inside the housing and is cylindrical. An opening is provided on the upper side of the housing, and a sealing cover is provided at the opening. The sealing cover is fixed at the opening by a bolt and nut assembly. By removing the bolt and nut assembly and opening the sealing cover, the melt filter inside the housing can be removed. After closing the sealing cover and installing the bolt and nut assembly, the housing is sealed. The bolt and nut assembly includes a nut and a bolt, with the nut located outside the housing.

[0003] During production, depending on the product, filter elements need to be replaced. For example, some filter elements need to be replaced about twice a month. The problems with replacing filter elements are: multiple bolt and nut assemblies are arranged around the circumference of the sealing cover, the distance between two adjacent nuts is small, the space is narrow, the individual nuts are large, and the nut thread spacing is small. After manually loosening the nuts, it takes about 5 minutes to unscrew them in the narrow space. Because the distance between two adjacent nuts is small, it is not possible to rotate the nuts continuously for many turns when loosening them manually. Each rotation is only about half a turn, which is time-consuming, labor-intensive, and inefficient. Moreover, the nut temperature reaches about 100℃. When operating manually, wearing gloves is necessary, the disassembly speed is slow, and burns are easy to occur. Utility Model Content

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] See Figures 1 to 6 The melt filter nut disassembly fixture shown includes a housing 11 and a filter element. The filter element is located inside the housing 11 and is cylindrical. An opening is provided on the upper side of the housing 11, and a sealing cover (not shown in the figure) is provided at the opening. The sealing cover is fixedly installed at the opening by a bolt and nut assembly. The bolt and nut assembly includes a nut 8 and a bolt 9, which are threadedly connected. The nut 8 is located outside the housing 11.

[0031] The disassembly fixture includes a fixing part 1, a connecting part 7, and an operating part for driving the fixing part 1 to rotate relative to the bolt, wherein:

[0032] The fixing part 1 is provided at the lower part of the connecting part 7. There is a gap between the fixing part 1 and the operating part. The fixing part 1 includes a receiving cavity. The lower side of the receiving cavity is open (an opening is made, and the opening communicates with the receiving cavity). The receiving cavity is configured to receive the nut 8 to be disassembled. The inner contour of the receiving cavity is configured to fit the nut 8 to be disassembled. During operation, the lower side of the receiving cavity faces downward so that the nut 8 to be disassembled can be quickly received in the receiving cavity.

[0033] The tooling also includes a baffle 2, which is located on the upper side of the receiving cavity. The baffle 2 is configured to abut against the nut 8 to be disassembled located in the receiving cavity (the baffle 2 abuts against the upper side of the nut 8). When the nut 8 to be disassembled is located in the receiving cavity of the fixing part 1, the baffle 2 provides support to prevent the tooling from falling, which is safe and makes the operation more stable.

[0034] See Figure 1-5 The baffle 2 is a horizontal plate. The baffle 2 has an opening that is connected to the receiving cavity, so that the bolt passes through and the nut 8 to be removed is received in the receiving cavity. The opening is circular and the diameter of the opening is smaller than the diameter of the nut to be removed. It is possible to observe whether the nut 8 to be removed is covered through the opening, which is convenient for operation.

[0035] In some embodiments, the outer contour of the fixing part 1 is adapted to the outer contour of the nut 8 to be removed, that is, the nut 8 to be removed is polygonal, and the fixing part 1 is also polygonal.

[0036] In this example, the operating part is located on the upper part of the connecting part 7. Operating the operating part causes the fixing part 1 and the connecting part 7 to rotate relative to the bolt 9.

[0037] The tooling has a nut disassembly working state. When it is in the nut disassembly working state, the receiving cavity of the fixing part 1 covers the nut 8, the operating part is located above the bolt 9 and the nut 8, and a gap is maintained between the operating part and the bolt 9. There are no obstacles when operating the operating part, and the driving fixing part 1 rotates relative to the bolt 9 at a fast speed. Compared with manually rotating the nut, the nut disassembly speed is faster.

[0038] In one embodiment, the operating unit includes a first operating element that is easy to hold and / or a second operating element 6 that cooperates with a power tool.

[0039] In some embodiments, the first operating element includes a column 3, which is easy to hold, and is disposed on the upper part of the connecting part 7, and extends in a vertical direction.

[0040] In some other embodiments, the first operating component includes a column 3 and a sleeve 4. The column 3 is disposed on the upper part of the connecting part 7 and extends in a vertical direction. The sleeve 4 is sleeved on the outside of the column 3. The inner diameter of the sleeve 4 is larger than the outer diameter of the column 3. The sleeve 4 rotates relative to the column 3. During operation, the sleeve 4 is held by hand, which drives the column 3 and the fixing part 1 to rotate relative to the bolt 9. During rotation, at least part of the inner circumference of the sleeve 4 maintains a gap with the outer circumference of the column 3.

[0041] Preferably, a limiting part 5 is provided at the upper end of the column 3. The limiting part 5 is configured to prevent the sleeve 4 from disengaging from the column 3, ensuring operational stability. See also Figure 1-5 The limiting part 5 is spherical, and the diameter of the limiting part 5 is larger than the diameter of the column 3.

[0042] In some embodiments, the second operating member 6 extends vertically and includes a mating section 61 and a connecting section 62. The mating section 61 is configured to mate with a power tool and is located at the upper end of the connecting section 62. The opposite ends of the connecting section 62 are connected to the mating section 61 and the connecting portion 7, respectively. See also Figure 1-5 The mating section 61 is cuboid in shape, and the connecting section 62 is cylindrical. The width of the mating section 61 is greater than the diameter of the connecting section 62. The column 3 is parallel to the mating section 61. The power tool is an electric wrench. Using the power tool in conjunction with the second operating part 6 saves time and effort.

[0043] In this example, the tooling also includes a connecting column, which connects the first operating member and the second operating member 6. See [link to tooling description]. Figure 2-5 The two ends of the connecting column 10 are respectively connected to the lower end of the column 3 and the connecting section 62. The connecting column 10 is perpendicular to the column 3 and the connecting section 62.

[0044] In some embodiments, the connecting part 7 includes a first segment 71 and a second segment 72. One end of the first segment 71 is connected to one end of the second segment 72. The operating part is disposed on the upper side of the first segment 71. The other end of the second segment 72 is connected to the fixing part 1. The second segment 72 extends in a vertical direction. The first segment 71 extends upward from its lower part to its upper part in a direction away from the second segment 72, that is, the first segment 71 and the second segment 72 form an obtuse angle.

[0045] In a preferred embodiment, the first segment 71 is located directly above the fixing part 1, that is, the first segment 71 of the connecting part 7 and the fixing part 1 are both located on the same side of the tooling.

[0046] Preferably, the operating part is located directly above the fixing part 1, and the center of the second operating member 6 can be coaxial with the center of the fixing part 1; the operating part is provided at one end of the upper side of the first section 71 of the connecting part 7, which is away from the second section 72, and the fixing part 1 is provided at the lower end of the second section 72 of the connecting part 7.

[0047] In this example, the connecting part 7 is plate-shaped, and both the first segment 71 and the second segment 72 of the connecting part 7 are plate-shaped.

[0048] The specific implementation method for disassembling the nut using the melt filter nut disassembly tool in this example is as follows:

[0049] The first implementation method is as follows: the tooling moves downward toward the nut to be removed, so that the nut 8 to be removed is accommodated in the receiving cavity of the fixing part. The first operating member is operated to drive the fixing part 1 to rotate relative to the bolt, so as to remove the nut from the bolt, and then the sealing cover is removed.

[0050] The second implementation method is to use an electric wrench. The operating end of the electric wrench is engaged with the mating section 61 of the second operating member 6, which can quickly remove the nut from the bolt and then remove the sealing cap. This method is faster than the first one.

[0051] The advantages of the melt filter nut removal fixture in this example are:

[0052] By using the fixing part to hold the bolt to be removed, and then operating the operating part to drive the fixing part to rotate relative to the bolt, the nut is moved along the bolt, causing the nut to detach from the bolt. This allows for quick disassembly of the nut of the melt filter, improving work efficiency, and is simple and labor-saving; it saves manpower; and personnel do not need to directly contact the nut, ensuring high safety.

[0053] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
