Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a broken wire remover. Background Technology

[0002] In the tobacco industry, numerous pipelines exist for transporting materials such as tobacco shreds and flavorings. These pipelines form a complex material transport system and are crucial infrastructure for ensuring the smooth operation of the production process. However, over long-term use, due to aging of pipeline connecting components and vibration and wear during equipment operation, broken fibers frequently become lodged inside the pipelines. These broken fibers may originate from damaged seals at pipeline joints, metal wires produced by the peeling off of the anti-corrosion layer on the inner wall of the pipeline, or fine filaments broken off from worn parts in the conveying equipment. Once these broken fibers become lodged in the pipeline, they not only hinder the normal transport of materials, leading to a decrease in production efficiency, but may also cause partial blockages in the pipeline and even damage equipment in subsequent production stages, affecting the continuity and stability of the entire tobacco production process.

[0003] Currently, the industry's existing technical means for removing broken tobacco fibers from pipes are relatively limited. Traditional methods typically involve manual processing by operators using simple tools such as chisels and pliers. First, operators need to tap the outside of the pipe to determine the approximate location of the broken fiber, then use chisels or other tools to tap the pipe in an attempt to loosen it, and finally use pliers or other tools to remove it from the pipe. This method has many drawbacks. On the one hand, the pipe space is confined, and the removal process is complex and cumbersome, requiring operators with extensive experience for precise positioning and operation, consuming a significant amount of time and effort, resulting in low efficiency and failing to meet the demands of high-efficiency production in the modern tobacco industry. On the other hand, during the chiseling process, the force and angle are difficult to precisely control, easily causing scratches, dents, and other damage to the inner wall of the pipe, compromising its integrity and shortening its lifespan. More seriously, the chisels and other metal tools may generate iron filings or other metal fragments during the striking process. These fragments remain inside the pipe and may mix into the tobacco material during subsequent material transportation, posing a potential threat to the quality and safety of tobacco products and creating significant production hazards. Utility Model Content

[0004] The purpose of this invention is to provide a broken filament extractor to solve the problems of the existing technology, which involves manually removing broken filaments using simple tools such as chisels and pliers, which is complicated, cumbersome, and inefficient; the use of chisels to strike pipes can easily cause scratches, dents, and other damage to the inner wall of the pipes, shortening their service life; and the use of chisels and other metal tools may produce iron filings or other metal fragments during the striking process. These fragments may remain in the pipes and may mix into the tobacco materials during subsequent material transportation, posing a potential threat to the quality and safety of tobacco products.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A broken wire extractor is provided, comprising:

[0007] The abutting assembly includes a first abutting member and a second abutting member, which can be inserted into the pipe and move in a direction that approaches or moves away from each other to release or abut against the broken wire.

[0008] A handle assembly is detachably connected to the first abutment and the second abutment, and the handle assembly can rotate the first abutment and the second abutment to remove the broken wire.

[0012] As an optional technical solution for the broken wire extractor, the curved walls of the first abutting part and the second abutting part are provided with concave and convex textures, and the concave and convex textures form a friction contact surface with the broken wire.

[0013] As an optional technical solution for the broken wire extractor, the broken wire extractor further includes a first fastener, and the first abutment further includes a first mounting portion. The first mounting portion has a first threaded hole, and the first fastener is screwed into the first threaded hole and abuts against the second abutment. Changing the screwing position of the first fastener and the first threaded hole changes the distance between the first abutment and the second abutment.

[0014] As an optional technical solution for the broken wire extractor, the broken wire extractor further includes a second fastener. The first mounting part has a first through hole, and the second abutment also includes a second mounting part with a second threaded hole.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0032] Current technology relies on simple tools like chisels and pliers for manual removal of broken tobacco fibers. This method has several drawbacks. First, the confined space of the pipes and the complex, tedious removal process require highly experienced operators for precise positioning and manipulation, consuming significant time and effort and resulting in low efficiency, failing to meet the demands of high-efficiency production in the modern tobacco industry. Second, the difficulty in precisely controlling the force and angle when using chisels to strike the pipes easily leads to scratches, dents, and other damage to the inner walls, compromising the pipe's integrity and shortening its lifespan. More seriously, the striking process with chisels and other metal tools may generate iron filings or other metal fragments. These fragments, remaining inside the pipes, may mix with the tobacco material during subsequent material transport, posing a potential threat to the quality and safety of tobacco products and creating significant production hazards.

[0033] To address the above problems, this embodiment provides a broken wire extractor, see reference. Figure 1 and Figure 2The broken filament extractor includes an abutment assembly 10 and a handle assembly 20. The abutment assembly 10 includes a first abutment member 11 and a second abutment member 12. The first abutment member 11 and the second abutment member 12 can be inserted into the pipe and move in a direction that approaches or moves away from each other to release or abut the broken filament. The handle assembly 20 can be detachably connected to the first abutment member 11 and the second abutment member 12. The handle assembly 20 can drive the first abutment member 11 and the second abutment member 12 to rotate, thereby removing the broken filament. The tight abutment between the first abutment member 11 and the second abutment member 12 and the broken filament has a large frictional force. By rotating the first abutment member 11 and the second abutment member 12 through the handle assembly 20, the broken filament is removed, improving the efficiency of broken filament removal; avoiding damage to other parts of the pipe, thus extending the pipe's lifespan; and avoiding the generation of impurities such as iron filings, thus improving the quality of tobacco products.

[0034] Specifically, the first abutting member 11 and the second abutting member 12 each include a first abutting portion 13, the cross-sectional shape of which is semi-circular. The two first abutting portions 13 can be combined into a cylinder and inserted into the pipe. Specifically, the first abutting member 11 and the second abutting member 12 also include a second abutting portion 14, the cross-sectional shape of which is semi-circular. The two second abutting portions 14 can be combined into a cylinder and inserted into the pipe. The radius of the second abutting portion 14 is different from the radius of the first abutting portion 13. In this embodiment, the end of the second abutting portion 14 abuts against the end of the first abutting portion 13, and the planar wall of the second abutting portion 14 is flush with the planar wall of the first abutting portion 13. The radius of the second abutting portion 14 is larger than the radius of the first abutting portion 13. That is, the two first abutting portions 13 and the two second abutting portions 14 combine to form a stepped cylinder to accommodate pipes of different diameters. In other embodiments, the first abutment portion 13 and the second abutment portion 14 may be disposed at both ends of the first abutment member 11 or at both ends of the second abutment member 12. In other embodiments, the first abutment portion 13 and the second abutment portion 14 may be configured as detachable structures to be interchangeable to accommodate pipes of different diameters. In other embodiments, the cross-sectional shape of the two first abutment portions 13 may be square or circular.

[0035] Furthermore, the curved walls of the first abutment portion 13 and the second abutment portion 14 are provided with concave and convex textures, which form a frictional contact surface with the broken wire. Specifically, the concave and convex textures can be set as a grid pattern, a dotted pattern, or a curved pattern, etc., to increase the friction between the first abutment portion 13 and the second abutment portion 14 and the broken wire, and reduce the probability of slippage between the first abutment portion 13 and the second abutment portion 14 and the broken wire.

[0036] Furthermore, the broken wire extractor also includes a first fastener 30, and the first abutment 11 includes a first mounting portion 15. The first mounting portion 15 has a first threaded hole 151. The first fastener 30 is screwed into the first threaded hole 151 and abuts against the second abutment 12. Changing the screwing position of the first fastener 30 and the first threaded hole 151 changes the distance between the first abutment 11 and the second abutment 12. Specifically, the first mounting portion 15 is configured as a block, the end face of the second abutment 14 is connected to the end face of the first mounting portion 15, and the first fastener 30 is configured as a bolt. Rotating the bolt changes the length extending out of the first threaded hole 151. The extended part is the gap between the first abutment 11 and the second abutment 12. By increasing the gap between the first abutment 11 and the second abutment 12, the first abutment 11 and the second abutment 12 are tightly abutted against the broken wire.

[0037] Furthermore, the broken wire extractor also includes a second fastener 40. The first mounting portion 15 has a first through hole 152, and the second abutment 12 also includes a second mounting portion 16 with a second threaded hole 161. The second fastener 40 passes through the first through hole 152 and is screwed into the second threaded hole 161 to connect the first abutment 11 and the second abutment 12. Specifically, the second mounting portion 16 is configured as a block, and the end face of the second abutment 14 is connected to the end face of the first mounting portion 15. In this embodiment, the planar wall of the first mounting portion 15 is flush with the planar wall of the second abutment 14, and the planar wall of the second mounting portion 16 is flush with the planar wall of the second abutment 14. The first abutment 11 and the second abutment 12 are both integrally formed, increasing the rigidity of the first abutment 11 and the second abutment 12.

[0038] Specifically, the second fastener 40 is a bolt that passes through the first through hole 152 and is screwed into the second threaded hole 161, thereby fixing the position between the first abutment 11 and the second abutment 12 and preventing the first abutment 11 and the second abutment 12 from separating from each other during rotation.

[0039] Furthermore, the first mounting part 15 has a second through hole 153, and the second mounting part 16 has a third through hole 162. The handle assembly 20 includes a handle rod 21, which passes through the second through hole 153 and the third through hole 162. Rotating the handle rod 21 causes the abutment assembly 10 to rotate. Specifically, the handle assembly 20 also includes a limiting rod 22 and an anti-detachment plug 23. The anti-detachment plug 23 has a third threaded hole, and the first end of the handle rod 21 is provided with an external thread. The anti-detachment plug 23 is screwed to the handle rod 21 to prevent the abutment assembly 10 from detaching from the first end of the handle rod 21. The limiting rod 22 is located at the second end of the handle rod 21 and is perpendicular to the handle rod 21 to prevent the abutment assembly 10 from detaching from the second end of the handle rod 21. In this embodiment, the anti-detachment plug 23 is spherical and its diameter is larger than the inner diameter of the second through hole 153 and the third through hole 162. In this embodiment, the end of the limiting rod 22 is provided with a hexagonal head to assist in fixing the first fastener 30 and the second fastener 40. In other embodiments, the end of the limiting rod 22 may also be configured in other shapes to engage with the first fastener 30 and the second fastener 40.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
