Description

Technical Field

[0001] This application relates to a disassembly and assembly tool for an adapter of an extruder probe, and also relates to a tool assembly for an extruder probe. Background Art

[0002] In the body of an extruder for polymers, various probes are usually installed. These probes are used to detect the temperature or pressure of the polymers being processed in the extruder. The probes generally have a substantially cylindrical shape and are screwed into the body of the extruder by means of threaded holes in the extruder. According to the requirements of production operation and maintenance, the probes need to be periodically removed from the body of the extruder for calibration. During the process of removing the probes, generally, the operator needs to temporarily empty the polymers in the extruder first and then perform the removal operation to prevent the polymers from leaking out through the threaded holes for the probes.

[0003] After emptying the polymers, there may still be a small amount of polymers remaining in the extruder. Therefore, during the entire process of removal, the temperature of the extruder and the probe itself needs to be maintained above a certain temperature. Otherwise, when the remaining polymers come into contact with the cold probe or the body of the extruder, they will cool and solidify, thus jamming the probe in the threaded hole of the extruder. However, since the extruder is maintained at a high temperature state, there is a risk that, in the case where the probe has been removed by the operator, a part of the remaining polymers from the upstream of the extruder may enter the threaded hole of the extruder in a molten state and solidify in the threaded hole. When the above situation occurs, it will be difficult for the operator to reinstall the probe into the threaded hole.

[0004] In addition, since the extruder and the probe respectively adopt different industry standards and specifications, the aperture diameter or thread form of the threaded hole for the probe in the extruder usually cannot match the outer diameter or thread of the commercially available conventional probes on the market. Therefore, in order to use the conventional probes, generally, a special adapter needs to be arranged between the probe and the threaded hole of the extruder to compensate for the aperture difference between the two or to adapt to the thread form of the threaded hole of the extruder, so that the conventional probe can be correctly fitted to the extruder.

[0005] However, since threaded connections are used both between the probe and the adapter and between the adapter and the threaded hole of the extruder, and it is difficult to ensure that the frictional force of the former threaded connection is always greater than that of the latter threaded connection, sometimes after the probe is removed, it will be found that the adapter remains in its original position in the threaded hole or has only shifted to a certain extent through the threaded connection. At this time, it is difficult to disassemble the adapter alone. Because the adapter is usually designed to be first installed on the probe and then the combined assembly of the two is installed in the threaded hole, there is often no conventional mating part for individual screwing on the adapter. Moreover, after the probe is removed, even if the adapter remains in the threaded hole, since the adapter itself is a hollow tube, there is still a risk that the polymer enters the threaded hole and solidifies in the threaded hole.

[0006] Due to the above problems, it is often necessary to send the entire extruder to the supplier and disassemble the extruder and the related probe at the supplier. Such an operation is very costly and delays the normal production process.

[0007] Therefore, it is desirable to propose a disassembly and assembly tool for the adapter of the extruder probe and a corresponding tool assembly to solve the technical problems of disassembling and assembling a special adapter and plugging the threaded hole of the extruder when the probe is removed. Summary of the Utility Model

[0034] To understand the present disclosure more clearly, first refer to Figures 4 to 6 , which shows an adapter 20 for an extruder probe engaged with a disassembly and assembly tool 10 according to the present disclosure.

[0035] As Figure 4 and Figure 5 shown, the adapter 20 is in the form of a generally hollow tube. The adapter 20 has an external thread 21 at the outer surface of the hollow tube for engaging with a threaded hole for an extruder probe on the extruder. Through this external thread 21, the adapter 20 can be screwed and fitted into the threaded hole for the extruder probe. The adapter 20 has an internal thread 22 at the inner surface of the hollow tube for engaging with the extruder probe. Through this internal thread 22, the extruder probe can be screwed and fitted into the adapter 20. Thus, it is allowed that the extruder probe can be mounted in the threaded hole for the extruder probe of the extruder by means of the adapter 20.

[0036] The hollow tube form of the adapter 20 defines a first outer diameter w1 and a first inner diameter n1. The first outer diameter w1 is equal to the inner diameter of the threaded hole for the extruder probe in the extruder. The first inner diameter n1 is equal to the outer diameter of the mating extruder probe.

[0037] The adapter 20 has a first notch 23 and a second notch 24 recessed from the end face of one end (shown as the left side in this embodiment). Referring to Figure 4 Figure, the first notch 23 and the second notch 24 are both located at the outer peripheral edge of the adapter 20 in the radial direction and are arranged opposite to each other along the direction of the first outer diameter of the hollow tube. Figure 5 Figure

[0038] The first notch 23 and the second notch 24 can be configured such that the outer surface and the inner surface of the hollow tube of the adapter 20 communicate radially. That is to say, the first notch 23 and the second notch 24 can be configured to penetrate the tube wall of the hollow tube of the adapter 20.

[0039] In the embodiment, it is also shown that the adapter 20 may have a guiding portion 25, but it can be understood that the guiding portion 25 is not necessary. The guiding portion 25 is used to guide the adapter 20 to smoothly enter the threaded hole when the adapter 20 is inserted into the threaded hole of the extruder and is conducive to centering the adapter 20 in the threaded hole. The guiding portion 25 extends outward from the other end opposite to the end of the adapter 20 provided with the notches 23, 24. The guiding portion 25 is also in the form of a hollow tube. The guiding portion 25 has an inner diameter the same as the first inner diameter n1 and has an outer diameter generally slightly smaller than the first outer diameter w1.

[0040] Next, referring to Figures 1 to 2 Figure, which shows an embodiment of a disassembly and assembly tool 10 for an adapter for an extruder probe according to the present disclosure. As Figure 1 shown, the disassembly and assembly tool 10 includes a main body 1, an operating portion 2 and an engaging portion 3.

[0041] The main body 1 extends along the longitudinal axis and has a cylindrical shape. The main body 1, as the main part of the disassembly and assembly tool, is used to carry and connect the operating part 2 and the engaging part 3. The main body 1 has a first end 4 and an opposite second end 5 along the longitudinal axis.

[0042] The main body 1 has a first diameter d1. The first diameter d1 is smaller than the first outer diameter w1 of the adapter 20 and larger than the first inner diameter n1. Thus, the disassembly and assembly tool 10 can be inserted into the threaded hole of the extruder, and at the same time, it allows the disassembly and assembly tool 10 to engage with the adapter and be able to rotate after engagement.

[0043] The main body 1 can be configured to have different lengths according to the depth of the threaded hole for the extruder probe.

[0044] The operating part 2 extends from the first end 4 along the longitudinal axis. The operating part 2 can cooperate with another tool so that the disassembly and assembly tool 10 can be rotated by the other tool. Therefore, the operating part 2 is configured to rotate the disassembly and assembly tool by applying a torque to the operating part 2.

[0045] Figure 1 The operating part 2 shown in is configured to have an external hexagonal shape, but it can be understood that other shapes of the operating part 2 are also feasible.

[0046] The outer diameter of the operating part 2 is less than or equal to the first diameter d1 of the main body 1. Preferably, the outer diameter of the operating part 2 is equal to the first diameter d1.

[0047] The engaging part 3 is used to cooperate with the first notch 23 and the second notch 24 of the adapter 20 to transmit the rotational movement of the disassembly and assembly tool 10 to the adapter, so that the adapter can be rotated to achieve the disassembly and assembly operation.

[0048] The engaging part 3 protrudes from the end face of the second end 5 along the longitudinal axis. The external shape of the engaging part 3 is designed such that the engaging part 3 can engage with the first notch 23 and the second notch 24 of the adapter 20

[0049] The engaging part 3 extends perpendicular to the end face of the second end 5 of the main body 1 by a certain distance. In some embodiments, the distance can be equal to or less than the recessed depth of the first notch 23 and the second notch 24 of the adapter 20.

[0050] In one embodiment, when the first notch 23 and the second notch 24 of the adapter 20 are configured such that the outer surface and the inner surface of the hollow tube of the adapter 20 are radially connected, the engaging part 3 can be an integrally formed elongated strip, and the elongated strip extends from the outer peripheral edge of the main body 1 of the disassembly and assembly tool 10 along the direction of the first diameter d1 to the opposite outer peripheral edge, as shown by the dashed line in Figure 2 and Figure 3Aas shown by reference numeral 3 in the drawings. In this embodiment, the first engaging portion 31 and the second engaging portion 32 may be portions located at both ends of the engaging portion 3 respectively. The integrally formed engaging portion 3 is not only beneficial to improving the strength of the engaging portion 3, but also easier to manufacture.

[0051] In another embodiment, as Figure 3B shown, the engaging portion 3 may include a first engaging portion 31 and a second engaging portion 32. The first engaging portion 31 and the second engaging portion 32 may be configured as two independent engaging portions. The first engaging portion 31 and the second engaging portion 32 may both be located along the radial direction at the outer peripheral edge of the main body 1 and be arranged opposite to each other along the direction of the first diameter d1 to correspond to Figure 5 the first notch 23 and the second notch 24 of the adapter 20 shown in. The outer shapes of the first engaging portion 31 and the second engaging portion 32 are set such that the first engaging portion 31 and the second engaging portion 32 can be engaged with the first notch 23 and the second notch 24 respectively.

[0052] In some embodiments, the first notch 23 and the second notch 24 of the adapter 20 may have a hollow portion with a rectangular cross-section, and the first engaging portion 31 and the second engaging portion 32 of the disassembly and assembly tool 10 may have extending portions with a corresponding rectangular cross-section, so that the extending portions of the first engaging portion 31 and the second engaging portion 32 of the disassembly and assembly tool 10 can be inserted into the hollow portions of the first notch 23 and the second notch 24 of the adapter 20.

[0053] In other embodiments, the extending portions of the first engaging portion 31 and the second engaging portion 32 of the disassembly and assembly tool 10 may have a shape that tapers from its root to its end to facilitate the easier insertion of the extending portions of the first engaging portion 31 and the second engaging portion 32 of the disassembly and assembly tool 10 into the hollow portions of the first notch 23 and the second notch 24 of the adapter 20.

[0054] The operating portion 2 and the engaging portion 3 of the disassembly and assembly tool 10 may be connected to the main body 1 of the disassembly and assembly tool 10 by means such as welding. Alternatively, the operating portion 2 and the engaging portion 3 may be integrally formed with the main body 1.

[0055] Next, with the aid of Figure 9 describe the operation of using the disassembly and assembly tool 10 to disassemble the adapter 20. Figure 9 FIG. shows a schematic diagram of the mutual positional relationship of the disassembly and assembly tool 10, the adapter 20 of the extruder probe, and the threaded hole 50 of the extruder 100 along the axial direction shown by the arrow A when operating.

[0056] When the adapter 20 remains in the threaded hole 50 of the extruder 100, the disassembly and assembly tool 10 is operated to be inserted into the threaded hole from the outside of the threaded hole 50 and approach the adapter 20 until it contacts the adapter 20. Then, the disassembly and assembly tool 10 is rotated so that its engaging portions 3 (specifically, the first engaging portion 31 and the second engaging portion 32) are correctly fitted with the first notch 23 and the second notch 24 of the adapter 20. After feeling that the disassembly and assembly tool 10 has been properly fitted with the adapter 20, another tool (for example, when the operating portion 2 has an external hexagonal shape, the other tool is an external hexagonal wrench) can be used to engage with the operating portion 2 of the disassembly and assembly tool 10 that extends out of the threaded hole 50 at this time, and the other tool is rotated. The rotation of the other tool causes the adapter in the threaded hole 50 to rotate until the adapter 20 is screwed out of the threaded hole 50, thereby realizing the disassembly of the adapter 20 from the threaded hole 50.

[0057] After the adapter 20 has been removed from the threaded hole 50 of the extruder 100, the threaded hole 50 needs to be blocked to prevent the polymer from further flowing into the threaded hole 50, thereby avoiding damage to the threaded hole 50. For this purpose, in combination with the above-mentioned disassembly and assembly tool 10 for the adapter of the extruder probe, the present disclosure also proposes a tool assembly for the extruder probe.

[0058] As described above, the extruder probe is installed in the threaded hole for the extruder probe in the extruder 100 by means of the adapter 20.

[0059] The tool assembly includes the aforementioned disassembly and assembly tool 10 and a plugging tool 40.

[0060] Reference Figure 7 , in which the plugging tool 40 is shown.

[0061] The plugging tool 40 includes a main body 41, an operating portion 42, and a plugging portion 43.

[0062] The main body 41 of the plugging tool 40 extends along a longitudinal axis and has a cylindrical shape. The main body 41 is used as the main part of the plugging tool 40 to carry and connect the operating portion 42 and the plugging portion 43. The main body 41 has a second diameter d2. The second diameter d2 is smaller than the first outer diameter w1 of the adapter 20.

[0063] The main body 41 can be configured to have different lengths according to the depth of the threaded hole of the extruder.

[0064] The operating portion 42 of the plugging tool 40 extends from the end face of one end of the main body 41 along the longitudinal axis. The operating portion 42 is used to cooperate with another tool so that the plugging tool 40 can be rotated by the other tool. Therefore, the operating portion 42 is configured to rotate the plugging tool by applying a torque to the operating portion 42.

[0065] Figure 7 The operating part 42 shown is configured to have an external hexagonal shape, but it is understood that other shapes of the operating part 2 are also feasible.

[0066] The outer diameter of the operating part 42 is less than or equal to the second diameter d2 of the main body 41. Preferably, the outer diameter of the operating part 42 is less than the second diameter d2.

[0067] The plugging part 43 of the plugging tool 40 is coaxial with the main body 41 and also has a cylindrical shape. The plugging part 43 is configured to extend outward from the outer surface of the main body 41 around the main body 41. The plugging part 43 has a second outer diameter w2, where the second outer diameter w2 is equal to the first outer diameter w1 of the adapter 20.

[0068] Preferably, the plugging part 43 is arranged closer to the end of the plugging tool 40 opposite to the end where the operating part 42 is located, so as to facilitate pre-placing the plugging tool 40 in the threaded hole of the extruder.

[0069] The plugging part 43 is provided with a thread 45 on the outer surface of its cylindrical shape. The thread 45 of the plugging part 43 is configured to engage with the internal thread of the threaded hole 50 of the aforementioned extruder 100 for the extruder probe so as to seal the threaded hole 50, thereby achieving the effect of preventing the polymer in the extruder from entering the threaded hole 50.

[0070] The operation of the plugging tool 40 is very convenient. After the extruder probe and the adapter 20 have been removed from the extruder 100, the plugging tool 40 is inserted into the threaded hole 50 of the extruder 100. Then, another tool is used to engage with the operating part 42 of the plugging tool 40 and the other tool is rotated. The rotation of the other tool causes the plugging tool 40 to rotate until the plugging tool 40 is screwed to a suitable position in the threaded hole 50, thereby achieving the sealing of the threaded hole 50.

[0071] Reference Figure 8 shows another embodiment of the plugging tool.

[0072] The plugging tool 400 of this embodiment is similar to the aforementioned plugging tool 40. The difference is that the plugging tool 400 only has the main body 41 and the plugging part 430, but does not have an operating part. In addition, the plugging part 430 is arranged along the longitudinal axis such that one end face of the plugging part 430 is flush with one end face of the main body 41. At the same time, the plugging part 430 has a notch 431 recessed from the end face at the end face. The internal shape of the notch 431 is designed such that the notch 431 can engage with the engaging part 3 of the disassembly and assembly tool 10.

[0073] The notch 431 can be in an elongated strip shape, and the elongated strip shape extends from the outer peripheral edge of the plugging portion 430 in the direction of the second outer diameter w2 to the opposite outer peripheral edge.

[0074] In yet another embodiment, similar to Figure 5 the first notch 23 and the second notch 24 of the adapter 20 shown, the notch 431 of the plugging portion 430 can include a third notch and a fourth notch. The third notch and the fourth notch are configured as two independent notches. Both the third notch and the fourth notch are located at the outer peripheral edge of the plugging portion 430 in the radial direction and are arranged opposite to each other in the direction of the second outer diameter w2.

[0075] The plugging tool 400 of this embodiment enables the plugging tool to be screwed into the threaded hole 50 of the extruder 100 by means of the disassembly and assembly tool 10 without using additional tools.
