Description

Technical Field

[0001] This utility model relates to a wire dust removal mechanism. Background Technology

[0002] In industrial control, automated measurement and other fields, draw-wire encoders are widely used as a common displacement detection device due to their advantages such as high measurement accuracy and convenient installation. Their core working principle is to acquire and convert displacement signals through the stretching and retraction of a draw wire, in conjunction with internal sensing components. However, as a key transmission component, the draw wire needs to be frequently extended and retracted during use, inevitably exposing it to complex working environments. However, in most application scenarios, the air is often mixed with fine particles such as dust. After long-term use, dust tends to continuously adhere to the surface of the draw wire and accumulate. Currently, traditional draw wire encoders are generally not equipped with dedicated dust removal devices for the draw wire, making it impossible to clean the draw wire in real time. When the draw wire is retracted, the dust adhering to its surface will enter the encoder's interior along with the wire. This not only accumulates on internal components, affecting the encoder's normal signal transmission and measurement accuracy, and shortening the equipment's lifespan, but more seriously, dust accumulation may increase the friction between the draw wire and the internal structure, causing the draw wire to jam and become unable to be retracted. Ultimately, this will cause the draw wire encoder to malfunction, adversely affecting the continuity and stability of industrial production. Utility Model Content

[0003] This utility model provides a wire-drawing dust removal mechanism, which aims to solve at least one of the technical problems existing in the prior art.

[0004] The technical solution of this utility model is a pull-cord dust removal mechanism, which includes a brush cleaning component, a filter cotton and a connecting joint. One end of the connecting joint is provided with a cavity for installing the filter cotton. The end of the connecting joint with the cavity is connected to the brush cleaning component, and the other end is connected to the pull-cord encoder. The pull cord passes through the brush cleaning component and the filter cotton in sequence, and then enters the pull-cord encoder through the connecting joint.

[0005] According to some embodiments of the present invention, the brush cleaning assembly includes a brush mounting sleeve and a brush. The brush mounting sleeve is connected to one end of the connecting joint that has the cavity, and the brush is mounted in the brush mounting sleeve.

[0006] According to some embodiments of the present invention, the brush cleaning assembly further includes a dustproof cover for pressing and fixing the brush in the brush mounting sleeve.

[0007] According to some embodiments of the present invention, the brush is an internally wound brush, comprising a spiral skeleton and brush bristles. The brush bristles are wound and distributed along the inner side of the spiral skeleton to form a central channel through which the pull wire passes. The spiral skeleton is used to install the brush bristles in the brush mounting sleeve.

[0008] According to some embodiments of this utility model, the brush bristles are made of nylon.

[0009] According to some embodiments of this utility model, the fine bristles of the brush are made of steel wire.

[0014] The beneficial effects of this utility model include: by setting up a dual cleaning structure of brush cleaning component and filter cotton, the draw wire first passes through the brush cleaning component during the recycling process, removing a large amount of dust adhering to the surface. Then, under the action of the filter cotton, the residual dust is further cleaned, minimizing the situation where dust is brought into the draw wire encoder. This avoids damage to the internal components of the draw wire encoder and a decrease in measurement accuracy due to dust accumulation, thus extending the service life of the equipment. It also prevents the draw wire from getting stuck due to dust adhesion, ensuring that the draw wire encoder can work continuously and stably, and improving its adaptability and reliability in complex dusty environments.

For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0024] Reference Figure 1 In some embodiments, the pull-cord dust removal mechanism according to the present invention includes a brush cleaning assembly 210, a filter cotton 220, and a connecting joint 230. One end of the connecting joint 230 is provided with a cavity for installing the filter cotton 220. The end of the connecting joint 230 with the cavity is connected to the brush cleaning assembly 210, and the other end is connected to the pull-cord encoder 300. The pull cord 100 passes through the brush cleaning assembly 210 and the filter cotton 220 in sequence, and then enters the pull-cord encoder 300 through the connecting joint 230.

[0025] It should be noted that, as Figure 2 As shown, the pull wire 100 passes through the pull wire dust removal mechanism 200 of this utility model before entering the wire encoder 300. Specifically, see... Figure 1 The dust removal mechanism 200 of this utility model consists of a brush cleaning component 210, a filter cotton 220, and a connecting joint 230. One end of the connecting joint 230 has a cavity for housing the filter cotton 220; this cavity end is connected to the brush cleaning component 210, and the other end is connected to the pull-wire encoder 300. In actual operation, the pull wire 100 first passes through the brush cleaning component 210, where the contact friction between the brush and the pull wire 100 initially removes the dust adhering to it. Then, the pull wire 100 passes through the filter cotton 220 placed in the cavity of the connecting joint 230 for secondary filtration and cleaning of any remaining dust. After these two cleaning processes, the pull wire 100 finally enters the pull-wire encoder 300 through the connecting joint 230. The dual cleaning action of the brush cleaning component 210 and the filter cotton 220 effectively removes dust adhering to the pull wire 100, preventing dust from entering the pull wire encoder 300 along with the pull wire 100. This ensures the normal operation of the pull wire encoder 300, prevents problems such as pull wire jamming and encoder malfunction caused by dust accumulation, helps extend the service life of the pull wire encoder 300, and improves its stability and reliability in dusty environments.

[0026] It should also be noted that this wire-based dust and powder removal mechanism is not limited to use with wire encoders; its application scenarios are more widely applicable. For various products that rely on wires for transmission, displacement detection, or other related operations, such as displacement sensors with wire-based structures, some wire-controlled automated actuators, and even some devices that use wires to transmit mechanical motion, wherever the wires are exposed to working environments containing dust and other impurities, and where cleaning of the wires is necessary to ensure normal equipment operation, this mechanism can provide reliable wire cleaning protection for these products with its effective dust and powder removal function. This helps various wire-related products maintain stable working performance under complex operating conditions, expanding its application scope and practical value.

[0027] According to some embodiments of this utility model, such as Figure 1 As shown, the brush cleaning assembly 210 includes a brush mounting sleeve 211 and a brush 212. The brush mounting sleeve 211 is connected to one end of the connecting joint 230 that has the cavity, and the brush 212 is installed in the brush mounting sleeve 211.

[0028] In some embodiments, such as Figure 1As shown, the brush cleaning assembly 210 includes a brush mounting sleeve 211 and a brush 212. The brush mounting sleeve 211 plays a key role in structural support and component assembly. One end of the sleeve is connected to the end of the connector 230 with a cavity to form a complete cleaning channel structure. The brush 212, as a cleaning component that directly acts on the pull cord 100, is fixedly installed inside the brush mounting sleeve 211. The installation position and posture of the brush 212 are adapted to ensure that the pull cord 100 can form sufficient and stable contact with the bristles of the brush 212 when passing through the brush mounting sleeve 211, laying a structural foundation for subsequent dust scraping and cleaning. The precise connection between the brush mounting sleeve 211 and the connecting joint 230 not only achieves a stable assembly of the brush cleaning component 210 and the overall mechanism, ensuring the stability of the structure during the cleaning process and preventing the cleaning position from shifting due to loose parts; at the same time, the built-in installation of the brush 212 inside the brush mounting sleeve 211 can effectively protect the brush 212, reduce the direct wear of the brush 212 by the external environment, and extend the service life of the brush 212.

[0029] According to some embodiments of this utility model, such as Figure 1 As shown, the brush cleaning assembly 210 also includes a dustproof cover 213 for pressing and fixing the brush 212 into the brush mounting sleeve 211.

[0030] It should be noted that, as Figure 1As shown, the brush cleaning assembly 210 adds a dustproof cap 213 to the brush mounting sleeve 211 and the brush. The core function of the dustproof cap 213 is to press and fix the brush 212 installed in the brush mounting sleeve 211. Through the adaptive connection with the brush mounting sleeve 211, the brush 212 can be stably limited to the preset installation position inside the sleeve, preventing the brush 212 from shifting or loosening due to the friction force generated when the pull cable 100 passes through the brush 212, and ensuring that the contact state between the brush 212 and the pull cable 100 is always stable. Meanwhile, when the dust accumulates between the fine bristles of the brush and on the filter cotton 220 after long-term use, affecting the cleaning effect, there is no need to disassemble the entire mechanism. Simply loosen and remove the dust cover 213 from the brush mounting sleeve 211, and you can directly take out the brush 212 inside the sleeve and the filter cotton 220 inside the connecting joint cavity. Then, you can clean the dust by blowing it with an air gun. After cleaning, reinstall the parts and tighten the dust cover 213, and the mechanism can be restored to normal use. The dust cover 213 serves two main purposes. First, by reliably clamping and securing the brush 212, it ensures the structural stability of the brush 212 during the cleaning process, preventing issues such as cleaning position deviation and incomplete dust removal due to brush 212 displacement. This ensures the continuity and reliability of the primary dust removal effect. Second, its detachable design greatly simplifies the maintenance process. The brush 212 and filter cotton 220 can be quickly disassembled, cleaned, and repositioned without the need for complex tools or specialized techniques, significantly reducing maintenance difficulty and time costs, and improving the ease of use of the mechanism. Furthermore, the dust cover 213 also provides a sealed protection to the open end of the brush mounting sleeve 211 during daily use, reducing the direct entry of dust from the external environment into the sleeve and its adhesion to the brush 212. This reduces the rate of dust accumulation on the brush 212 from the source, indirectly extending the cleaning cycle and service life of the brush 212, further ensuring the overall dust removal efficiency of the mechanism.

[0031] According to some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the brush 212 is an internally wound brush, including a spiral skeleton and brush bristles. The brush bristles are wound and distributed along the inner side of the spiral skeleton to form a central channel through which the pull wire 100 passes. The spiral skeleton is used to install the brush bristles in the brush mounting sleeve 211.

[0032] It should be noted that, as Figure 1 and Figure 3As shown, the brush 212 adopts an internally wound structure design, mainly composed of a spiral skeleton and brush bristles. The spiral skeleton serves as the supporting foundation for the brush bristles, providing a stable mounting carrier and, through its structural adaptability, enabling the brush 212 to be positioned and installed within the brush mounting sleeve 211. The brush bristles are distributed in a wound pattern along the inner side of the spiral skeleton, forming a central channel through which the pull cord 100 passes. The diameter of this channel matches the diameter of the pull cord 100, ensuring that the pull cord 100 makes full contact with the inner surrounding brush bristles when passing through the channel, providing ample conditions for dust scraping. This internally wound structure causes the brush bristles to wrap around the pull cord 100, avoiding the existence of blind spots in cleaning.

[0033] According to some embodiments of this utility model, the brush bristles are made of nylon.

[0034] In some embodiments, the brush bristles are made of nylon. Nylon, as a common polymer synthetic material, possesses excellent physical properties and processing adaptability. It can be tightly attached to the inner side of the spiral skeleton through a specific winding process, forming a uniform and moderately dense layer of brush bristles. Furthermore, the length and hardness of the bristles can be precisely controlled during processing, ensuring effective contact with the pull cord surface without compromising cleaning performance due to excessive hardness or softness. This adapts to the dynamic friction cleaning requirements during pull cord retrieval. It is understood that the material of the brush bristles can be selected according to actual needs, and this invention does not limit the material of the brush bristles.

[0035] According to some embodiments of this utility model, the fine bristles of the brush are made of steel wire.

[0036] It should be noted that in some embodiments, for applications where stubborn dust, particulate impurities, or slight oil stains easily adhere to the surface of the pull wire, the brush bristles are made of steel wire. Due to its high strength, steel wire can be precisely wound into the inner side of a spiral frame, forming a bristle layer that combines hardness and toughness. The diameter and density of the steel wire bristles can be customized according to actual cleaning needs, ensuring sufficient scraping force when in contact with the pull wire. Simultaneously, the structural stability of the steel wire itself prevents deformation or breakage during long-term friction, making it suitable for high-load, high-cleaning conditions. Furthermore, steel wire has strong chemical stability, and in harsh environments containing corrosive dust or high humidity, it is not prone to corrosion or performance degradation, maintaining stable cleaning capabilities. This further expands the application range of this dust removal mechanism in complex conditions such as heavy industry and outdoor engineering, ensuring the long-term stable operation of the pull-wire encoder. It is understood that the material of the brush bristles can be selected according to actual needs, and this invention does not limit the material of the brush bristles.

[0037] According to some embodiments of this utility model, such as Figure 1 As shown, the filter cotton 220 is cylindrical, and the outer diameter of the filter cotton 220 is adapted to the inner diameter of the cavity.

[0038] It should be noted that, as Figure 1 As shown, the filter cotton 220 is cylindrical, and its outer diameter matches the inner diameter of the cavity, allowing the filter cotton 220 to fit tightly against the inner wall of the cavity. This tight packing prevents gaps from appearing due to the movement of the filter cotton 220 when the pull cord 100 passes through it. This prevents residual dust from bypassing the filter cotton 220 and entering the pull-cord drive device, ensuring the thoroughness of secondary dust removal. In addition, the tight packing keeps the filter cotton 220 stable within the cavity, preventing displacement due to the stretching and retraction of the pull cord 100. This ensures that the filter cotton 220 is always in the preset clean position, maintaining a stable filtration effect. The cylindrical structure not only facilitates the processing and manufacturing of the filter cotton 220 but also allows it to be evenly stressed within the cavity, reducing damage caused by uneven stress and extending the service life of the filter cotton 220.

[0039] According to some embodiments of this utility model, such as Figure 1 As shown, the connecting connector 230 is connected to the brush cleaning assembly 210 by a thread.

[0040] It should be noted that, for example Figure 1 As shown, the connecting joint 230 and the brush cleaning assembly 210 are connected by a threaded connection. Firstly, the self-locking characteristic of the threaded engagement ensures reliable fixation between the two, preventing loosening of the connection due to external forces such as vibration and cable pulling during long-term use, thus ensuring the stability of the overall structure and maintaining the continuous reliability of the cleaning function. Secondly, the threaded connection provides excellent ease of assembly and disassembly. If deep maintenance or replacement of the brush 212 inside the brush cleaning assembly 210 or the filter cotton 220 inside the connecting joint 230 is required, the two can be separated simply by rotating the brush mounting sleeve 211 in the reverse direction, without the need for complex tools, simplifying the maintenance process and reducing the difficulty of maintenance.

[0041] According to some embodiments of this utility model, such as Figure 1 As shown, the connector 230 is connected to the wire encoder 300 by a thread.

[0042] It should be noted that, as Figure 1As shown, the connector 230 and the pull-coil encoder 300 are connected by a threaded connection. Specifically, the end of the connector 230 away from the brush cleaning component 210 is pre-threaded with an external or internal thread to match the structural specifications of the pull-coil encoder 300's outlet. The outlet end of the pull-coil encoder 300 is machined with a matching internal or external thread. During assembly, the connector 230 is rotated to precisely engage the threads of both, until a tight fit is achieved. This stably connects the dust removal and powder removal mechanism and the pull-coil encoder 300 into a single unit, ensuring that the double-cleaned pull-coil 100 can accurately enter the pull-coil encoder 300 through the connector 230, forming a complete pull-coil transmission and cleaning closed loop. This achieves a high-strength fixation between the two, effectively resisting the axial tension and vibration generated during the wire pull and recovery process, avoiding loosening of the connection during long-term use, ensuring the stability of the mechanism and encoder working together, and thus ensuring the accuracy of wire displacement detection; secondly, the threaded connection is simple and convenient to disassemble and assemble. If the dust removal and powder removal mechanism needs to be maintained or replaced, or the wire encoder 300 needs to be repaired, the connection joint 230 can be separated simply by rotating it in the opposite direction, without disassembling the complex structure, which greatly reduces the difficulty of operation and maintenance time costs.

[0043] According to some embodiments of this utility model, such as Figure 1 As shown, both the brush cleaning assembly 210 and the connecting joint 230 are provided with multiple pull tube plugs 240, and the center of each pull tube plug 240 has a through hole for the pull tube 100 to pass through.

[0044] It should be noted that, as Figure 1As shown, both the brush cleaning assembly 210 and the connector 230 are equipped with multiple cable guide caps 240, which are installed at key passage positions for the cable 100, such as the cable inlet of the brush cleaning assembly 210 and the cable outlet of the connector 230 near the filter cotton 220. Each cable guide cap 240 has a through hole machined in its center for the cable 100 to pass through. The diameter of the through hole is precisely designed to match the diameter of the cable 100, ensuring that the cable 100 can pass through smoothly, while avoiding the cable 100 from shifting due to an excessively large hole diameter or the cable 100 from increasing frictional wear due to an excessively small hole diameter. The multiple pull cord plugs 240 provide multi-node guidance and limitation for the movement trajectory of the pull cord 100 within the mechanism. This effectively prevents the pull cord 100 from deviating due to uneven force during stretching or retraction, avoids it scraping against the inner wall of the brush cleaning component, the edge of the connecting joint cavity, and other components, reduces frictional loss between the pull cord 100 and the mechanism, and protects the surface structural integrity of the pull cord 100. Simultaneously, the through-holes adapted to the diameter of the pull cord 100 ensure that it always moves along a preset path, allowing it to accurately pass through the central channel of the internally wound brush and the filter cotton 220. This ensures that the brush bristles and filter cotton 220 make full contact with the pull cord 100, preventing cleaning blind spots caused by pull cord deviation and improving the thoroughness of dust and powder removal. Furthermore, the pull cord plugs 240 also provide a certain degree of sealing protection for the internal channels of the mechanism, reducing the entry of external dust into the mechanism from the pull cord inlet or outlet gaps, further enhancing the dustproof effect and ensuring the long-term stable operation of the mechanism.

[0045] The beneficial effects of this utility model include: by setting up a dual cleaning structure of brush cleaning component and filter cotton, the draw wire first passes through the brush cleaning component during the recycling process, removing a large amount of dust adhering to the surface. Then, under the action of the filter cotton, the residual dust is further cleaned, minimizing the situation where dust is brought into the draw wire encoder. This avoids damage to the internal components of the draw wire encoder and a decrease in measurement accuracy due to dust accumulation, thus extending the service life of the equipment. It also prevents the draw wire from getting stuck due to dust adhesion, ensuring that the draw wire encoder can work continuously and stably, and improving its adaptability and reliability in complex dusty environments.

[0046] The above description is merely a preferred embodiment of this utility model. This utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effect, should be included within the scope of protection of this disclosure and fall under the protection scope of this utility model. Within the protection scope of this utility model, the technical solutions and / or implementation methods can have various modifications and variations.
