Description

Technical Field

[0001] This utility model belongs to the field of adhesive roller technology, and specifically relates to an adjustable length adhesive roller. Background Technology

[0002] Sticky rollers are a widely used cleaning tool in many fields. They typically consist of a cylindrical wheel and an adhesive surface. The adhesive surface of the sticky roller can effectively adsorb tiny particles such as dust, hair, and fibers. In industries such as electronics manufacturing, printing, and optics, sticky rollers are often used to clean product surfaces and remove impurities generated during the production process to ensure product quality. Their working principle is that when the sticky roller comes into contact with the surface of the object to be cleaned, the adhesive surface firmly adheres to the dust and other particles. Sticky rollers have advantages such as ease of use, good cleaning effect, and reusability. Depending on the application scenario, sticky rollers are available in different sizes and adhesive strengths. Some sticky rollers also allow for the replacement of the adhesive surface to extend their service life. In short, sticky rollers play an important role in keeping object surfaces clean and improving production quality.

[0003] Chinese patent CN219401468U discloses an adjustable dust roller, comprising: a long rod with a ring rotatably mounted on its outer surface and a mounting plate fixedly mounted on the outer surface of the ring; two extension tubes slidably mounted on both ends of the long rod, with a dust-adhesive sleeve covering the outer surface of each extension tube, one end of which is placed inside the extension tube; and a fixing member mounted on the outer surface of the long rod for detachably fixing the dust-adhesive sleeve. This invention achieves adjustable length of the dust roller through the cooperation of the extension tubes, dust-adhesive sleeve, fixing member, tape, and limiting member, avoiding the inconvenience of moving the dust roller or the position of the product being cleaned due to insufficient length, thus greatly reducing the labor intensity of workers and improving the efficiency of cleaning impurities, dust, and other dirt.

[0004] During the use of the aforementioned device, although it employs the method of attaching extension cylinders to both ends of a long rod and adjusting the distance between the two extension cylinders by sliding them on the long rod to achieve the function of length adjustment, there are still obvious defects and shortcomings in its overall use. First, its length adjustment relies entirely on manual operation. When the dust-adhesive wheel is extended to a high position for dust-adhesive work, if the length needs to be adjusted, the entire device must be moved to the bottom to make the adjustment. This method greatly limits its flexibility and convenience. In practical application scenarios, especially in situations where frequent length adjustments are needed to adapt to different dust-adhesive heights, this adjustment method is extremely inconvenient. For example, in some large workshops or warehouses, dust at high positions may require constant adjustments to the position and length of the dust-adhesive wheel for effective cleaning, and the existing device cannot quickly and flexibly meet this need. It is evident that it does have certain defects in its use and urgently needs improvement and optimization. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an adjustable length dust-sticking wheel to solve the problem that existing equipment requires manual adjustment during use, which is obviously inconvenient to adjust when it is in a high position for dust sticking.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An adjustable-length dust-sticking wheel includes a telescopic rod, an installation plate fixedly mounted at the end of the telescopic rod, an adjustment mechanism fixedly mounted at the bottom of the installation plate, and dust-sticking wheel assemblies fixedly mounted at both ends of the bottom of the adjustment mechanism.

[0008] The dust-adhesive wheel assembly includes a vertical plate, which is fixedly installed on both sides of the bottom of the adjustment mechanism. A support shaft is fixedly installed on the lower inner side of the vertical plate. A dust-adhesive wheel is fitted on the outer surface of the support shaft. An external thread is formed on the outer surface of the inner end of the support shaft. A limit sleeve is threaded to the inner end of the support shaft through the external thread. The inner side of the limit sleeve and the inner side of the dust-adhesive wheel are fitted together. A dust-adhesive sticker is provided on the outer surface of the dust-adhesive wheel.

[0009] As a preferred technical solution, the inner side of the limiting sleeve is provided with an annular groove, and anti-slip protrusions are fixedly connected at equal intervals inside the annular groove.

[0010] As a preferred technical solution, the adjustment mechanism includes a fixed frame, which is fixedly installed on the bottom of the mounting plate. A dual-axis motor is fixedly installed on the inner side of the fixed frame. Guide rails are fixedly connected to both sides of the fixed frame. A lead screw is rotatably connected inside the guide rail. The threads of the lead screws on both sides of the fixed frame are opposite. A slide is threadedly connected to the outer surface of the lead screw. The slide is slidably connected to the inside of the vertical rail. The bottom of the slide is fixedly connected to the top of the vertical plate.

[0011] As a preferred technical solution, the side of the carriage is cross-shaped, and the internal cross-sectional shape of the guide rail is also cross-shaped.

[0012] As a preferred technical solution, the telescopic rod includes a sleeve, a sliding tube is slidably connected to the inner side of the sleeve, a connecting arm is fixedly installed at the end of the sliding tube, the outer end of the connecting arm is fixedly connected to the mounting plate, a handrail tube is fixedly installed at the end of the sleeve away from the connecting arm, limit holes are equally spaced on one side of the sliding tube, and a hand-tightening screw is threaded to one end of the sleeve near the connecting arm, the end of the hand-tightening screw being inserted into the inner side of the limit hole.

[0013] As a preferred technical solution, a battery is fixedly connected to the inside of the handrail tube, and the battery is electrically connected to the dual-axis motor through wires. A control button is provided on the top of the handrail tube, and the wires of the battery inside the handrail tube are hidden inside the slide tube and the sleeve.

[0014] As a preferred technical solution, the overall cross-sectional shape of the sliding tube and the internal cross-sectional shape of the sleeve are both set to regular hexagons, and a bridge-type handrail is fixedly connected to the top of the sleeve near the side of the handrail tube.

[0015] In summary, the present invention has the following main advantages:

[0016] First, this device is equipped with a telescopic rod, whose length can be flexibly adjusted by adjusting the sliding tube inside the sleeve to adapt to high-position dust-sticking operations. After length adjustment, the hand-tightened screw is inserted into the limiting hole for fixation to ensure stability. It adopts an adjustment mechanism powered by a battery inside the handrail tube. Pressing the control button controls the operation of the dual-axis motor, which can be adjusted even in high-position dust-sticking conditions without removing the dust-sticking wheel assembly. The handrail tube and bridge handrail work together to facilitate two-hand operation, improving ease of use. The combination of manual adjustment and automatic control makes adjustment efficient and convenient, bringing a comfortable experience to users.

[0017] Secondly, the dust-adhesive wheel assembly of this device works in conjunction with the adjustment mechanism. The dual-axis motor is driven by the control button, causing the two screws with opposite threads to rotate, which in turn drives the slide and dust-adhesive wheel to move, thus achieving automatic adjustment of the spacing. The two screws run synchronously, and the adjustment accuracy is higher than that of manual adjustment. When it is necessary to disassemble and replace the dust-adhesive wheel, you can put your hand into the annular groove and twist the limit sleeve to disengage it from the external thread by using the anti-slip protrusion. The whole device is easy to adjust and disassemble and replace quickly, with strong adaptability and convenient use, and is worth promoting and applying. Attached Figure Description

[0023] refer to Figures 1 to 4 An adjustable-length dust-sticking wheel according to this embodiment includes a telescopic rod 1, an installation plate 4 is fixedly installed at the end of the telescopic rod 1, an adjustment mechanism 3 is fixedly installed at the bottom of the installation plate 4, and dust-sticking wheel assemblies 2 are fixedly installed at both ends of the bottom of the adjustment mechanism 3.

[0024] The dust-adhesive wheel assembly 2 includes a vertical plate 21, which is fixedly installed on both sides of the bottom of the adjustment mechanism 3. A support shaft 22 is fixedly installed on the lower inner side of the vertical plate 21. A dust-adhesive wheel 23 is fitted onto the outer surface of the support shaft 22. An external thread 24 is formed on the outer surface of the inner end of the support shaft 22. A limit sleeve 25 is threadedly connected to the inner end of the support shaft 22 through the external thread 24. The inner side of the limit sleeve 25 and the inner side of the dust-adhesive wheel 23 are fitted together. A dust-adhesive sticker is provided on the outer surface of the dust-adhesive wheel 23. The telescopic rod 1 allows the device to flexibly adjust its length according to actual usage needs, thereby adapting to dust-adhesive operations at different heights and greatly improving the applicability of the device. The mounting plate 4 provides a stable mounting base for the adjustment mechanism 3. The presence of this allows for more precise position adjustment of the sticky roller assemblies 2 at both ends of the bottom. The upright plate 21 in the sticky roller assembly 2 provides stable support for the support shaft 22 and the sticky roller 23. The sticky roller 23, fitted on the outer surface of the support shaft 22, works in conjunction with the sticky adhesive to effectively adsorb dust and other impurities, ensuring a cleaning effect. The external thread 24 at the inner end of the support shaft 22 engages with the limiting sleeve 25, facilitating the installation and removal of the sticky roller 23. When it is necessary to replace the sticky adhesive or the sticky roller 23, the operation is simple and quick. Overall, this adjustable-length sticky roller is reasonably designed, powerful in function, and has the advantages of adjustable length, good cleaning effect, and easy disassembly and replacement, providing an efficient and convenient solution for various dust-adhesive scenarios.

[0025] refer to Figure 4 The inner side of the limiting sleeve 25 is provided with an annular groove 26, and anti-slip protrusions 27 are fixedly connected at equal intervals inside the annular groove 26. In this adjustable-length sticky roller, the annular groove 26 and the anti-slip protrusions 27 fixedly connected at equal intervals inside the limiting sleeve 25 have significant advantages. The annular groove 26 provides a convenient force application point for operation. When it is necessary to remove or install the limiting sleeve 25, people can insert their fingers into the annular groove 26 to easily twist the limiting sleeve 25. The anti-slip protrusions 27 further enhance the stability and reliability of the operation. When twisting, the anti-slip protrusions 27 can effectively increase the friction between the fingers and the limiting sleeve 25, preventing the fingers from slipping, making the operation smoother and more efficient. Such design details not only improve the convenience of using the sticky roller, but also ensure that the installation and removal of the sticky roller 23 can be carried out quickly and accurately, bringing a better user experience. At the same time, it is also conducive to improving the maintenance efficiency and service life of the sticky roller.

[0026] refer to Figures 1-3The adjustment mechanism 3 includes a fixed frame 31, which is fixedly installed on the bottom of the mounting plate 4. A dual-axis motor 32 is fixedly installed on the inner side of the fixed frame 31. Guide rails 33 are fixedly connected to both sides of the fixed frame 31. Lead screws 34 are rotatably connected inside the guide rails 33. The threads of the lead screws 34 on both sides of the fixed frame 31 have opposite directions. A slide 35 is threadedly connected to the outer surface of the lead screws 34. The slide 35 is slidably connected to the inside of the vertical rail. The bottom of the slide 35 is fixedly connected to the top of the vertical plate 21. The side of the slide 35 is cross-shaped. The internal cross-section of the guide rail 33 is also cross-shaped. The fixed frame 31 provides a stable installation position for the dual-axis motor 32, ensuring that the motor will not shake during operation. The dual-axis motor 32 allows the lead screws 34 on both sides to rotate simultaneously, improving the adjustment efficiency. In terms of synchronization, the guide rails 33 on both sides of the fixed frame 31 provide a precise track for the movement of the lead screw 34 and the slide 35, ensuring that the slide 35 can slide stably within the guide rail 33. Since the threads of the lead screw 34 on both sides of the fixed frame 31 are opposite, when the lead screw 34 rotates, it can drive the two slides 35 to move in opposite directions within the guide rail 33, thereby enabling the dust-adhesive wheel assembly 2 to flexibly adjust the spacing to meet different dust-adhesive needs. The side shape of the slide 35 and the internal cross-sectional shape of the guide rail 33 are both arranged in a cross shape. This design can effectively prevent the slide 35 from rotating or detaching from the guide rail 33 during movement, ensuring the stability and accuracy of the movement. Overall, the design of the adjustment mechanism 3 makes the dust-adhesive wheel more flexible, efficient, and stable during use, providing users with a better dust-adhesive experience.

[0027] refer to Figures 1-3The telescopic rod 1 includes a sleeve 11, a slide tube 12 slidably connected to the inner side of the sleeve 11, a connecting arm 13 fixedly installed at the end of the slide tube 12, and a fixed connection between the outer end of the connecting arm 13 and the mounting plate 4. A handrail tube 14 is fixedly installed at the end of the sleeve 11 away from the connecting arm 13. Limiting holes 15 are equally spaced on one side of the slide tube 12. A hand-tightening screw 16 is threadedly connected to one end of the sleeve 11 near the connecting arm 13. The end of the hand-tightening screw 16 is inserted into the inner side of the limiting hole 15. A battery is fixedly connected to the inner side of the handrail tube 14 and the battery is connected to the wall. Electrically connected to the dual-axis motor 32 via wires, the top of the handrail tube 14 is equipped with a control button 17. The battery wires inside the handrail tube 14 are hidden inside the slide tube 12 and the sleeve 11. The overall cross-sectional shape of the slide tube 12 and the internal cross-sectional shape of the sleeve 11 are both set as regular hexagons. A bridge-type handrail 18 is fixedly connected to the top of the sleeve 11 near the side of the handrail tube 14. The design of the sleeve 11 and the slide tube 12 allows the telescopic rod 1 to be flexibly adjusted in length by sliding the slide tube 12 inside the sleeve 11, meeting the dust collection needs at different heights. Arm 13 securely connects the slide tube 12 to the mounting plate 4, ensuring the stability of the entire structure. Handrail tube 14 provides a handhold for easy operation, and the internal battery powers the dual-axis motor 32 via wires, making energy supply more convenient. The extended length of the slide tube 12 can be easily fixed by inserting the hand-tightening screw 16 into the limiting holes 15 at different positions, ensuring the telescopic rod 1 does not extend or retract arbitrarily during use. The control button 17 allows users to easily operate the dual-axis motor 32, improving ease of operation. The battery wires inside the handrail tube 14 are hidden inside the slide tube 12 and sleeve 11, resulting in a cleaner appearance and avoiding the risk of damage from exposed wires. Both the slide tube 12 and sleeve 11 have a regular hexagonal cross-section, preventing the slide tube 12 from rotating inside the sleeve 11 and ensuring the stability of the telescopic rod 1 during use. The bridge-type handrail 18 at the top of the sleeve 11 further enhances operational convenience, allowing users to operate with both hands, improving the efficiency and stability of the dust-collecting wheel.

[0028] Operating principle and advantages: By setting up the telescopic rod 1, the length of the entire telescopic rod 1 can be flexibly adjusted and extended during use by sliding the slide tube 12 inside the sleeve 11. This allows for flexible adjustment of the length according to actual needs, making the device perfectly suited for high-position dust-collecting operations. Furthermore, after length adjustment, simply twisting the hand-operated screw 16 and inserting it into the corresponding limiting hole 15 provides auxiliary fixation, ensuring the stability of the telescopic rod 1 during use. In addition, the device also employs an adjustment mechanism 3 during use... The adjustment mechanism 3 can be powered by the battery inside the handrail tube 14. Simply press the control button 17 to operate the dual-axis motor 32. In this way, even when the device is extended to stick dust to a high place, it can still be adjusted without removing the dust sticking wheel assembly 2 for adjustment. The whole device adopts a combination of manual adjustment and automatic control, which makes the adjustment more efficient and convenient. Moreover, during use, the cooperation between the handrail tube 14 and the bridge handrail 18 makes it easy to operate the device with both hands, further improving the ease of use of the device and bringing a more comfortable user experience.

[0029] By setting the dust-adhesive wheel assembly 2 and the adjusting mechanism 3 to work together, the device can be driven by the dual-axis motor 32 via the control button 17 during use. When the dual-axis motor 32 rotates, it can simultaneously drive the two lead screws 34 to rotate inside the guide rail 33. Since the threads of the two lead screws 34 are opposite, the two lead screws 34 can drive the two slides 35 to move in opposite directions inside the guide rail 33, thereby driving the dust-adhesive rollers 23 to reciprocate and move, realizing flexible adjustment of the distance between the two dust-adhesive rollers 23. It can be seen that the entire device can achieve self-adjustment. The automated adjustment, with the two lead screws 34 operating synchronously, enables the two dust-adhesive wheel assemblies 2 to adjust synchronously. Compared to manual adjustment, the overall adjustment accuracy is higher. In addition, during use, when it is necessary to disassemble and replace the dust-adhesive sleeve wheel 23, simply put your hand into the annular groove 26. At this time, the anti-slip protrusion 27 can play a good anti-slip role. Then, twist the limiting sleeve 25 to disengage from the external thread 24, and the dust-adhesive sleeve wheel 23 can be disassembled. It can be seen that this device is easy to adjust and disassemble quickly, has stronger adaptability, and is more convenient to use. It is very worthy of promotion and application.
