Description

Technical Field

[0002] During the production process of ultra-clear glass, when the glass moves slowly during the forming stage, the traction wheel of the edge drawing machine clamps the glass to prevent it from shrinking and deforming inward.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0050] During the production process of ultra-clear glass, when the glass moves slowly during the forming stage, the traction wheel of the edge drawing machine clamps the glass to prevent it from shrinking and deforming inward. In addition, the inner rod of the edge drawing machine is used to assist in supporting the side of the glass to ensure that the shape of the glass meets the requirements, thus laying the foundation for subsequent processing.

[0051] During operation, cooling liquid is introduced into the inner rod of the edge drawing machine to dissipate heat generated by the rod and prevent deformation due to overheating, which could affect the quality of the glass sheet. However, over time, impurities in the cooling liquid tend to settle on the inner wall of the inner rod, gradually forming blockages. These blockages affect the cooling efficiency of the inner rod, reducing its service life and increasing production costs.

[0052] In the prior art, blockages are generally cleared directly with a brush. However, when the brush penetrates the inner wall of the inner rod for cleaning, the brush may scratch the inner wall of the inner rod during the cleaning process, thereby causing wear and tear on the inner wall of the inner rod and reducing the service life of the inner rod.

[0053] The present invention proposes a cleaning device 100 , which aims to clean the inner wall of the inner rod 200 while reducing the wear on the inner rod 200 and increasing the service life of the inner rod 200 .

[0054] See also Figure 1In one embodiment of the present invention, the cleaning device 100 is used to clean the inner rod 200 of a glass edge drawing machine. The inner rod 200 has a flow channel 203 and an inlet 201 and an outlet 202 respectively connected to the two ends of the flow channel 203. The cleaning device 100 includes a fixing mechanism 1, a knocking mechanism 2, and a cleaning mechanism 3. The fixing mechanism 1 is used to fix the inner rod 200. The knocking mechanism 2 includes a driving assembly 21 and a knocking assembly 22 connected to each other. The driving assembly 21 drives the knocking assembly 22 to move along the extension direction of the inner rod 200. The knocking assembly 22 is used to knock the outer wall of the inner rod 200 to dislodge obstructions in the flow channel 203. The cleaning mechanism 3 includes a pipeline 31 and a cleaning medium. The two ends of the pipeline 31 are connected to the inlet 201 and the outlet 202 respectively. The pipeline 31 and the flow channel 203 form a circulation loop 6, and the cleaning medium is filled in the circulation loop 6. The cleaning mechanism 3 drives the cleaning medium to flow along the circulation loop 6, so that obstructions are discharged from the inner rod 200 along the flow channel 203.

[0055] In the present embodiment, a flow channel 203 is provided inside the inner rod 200, and an inlet 201 and an outlet 202 are respectively provided at both ends for introducing and discharging a cleaning medium. The cleaning device 100 is composed of three parts: a fixing mechanism 1, a knocking mechanism 2 and a cleaning mechanism 3. The fixing mechanism 1 is responsible for stably fixing the inner rod 200 to ensure stability during the cleaning process. The knocking mechanism 2 is composed of a driving assembly 21 and a knocking assembly 22. The driving assembly 21 drives the knocking assembly 22 to move along the extension direction of the inner rod 200, and generates vibration by knocking the outer wall of the inner rod 200, so that the blockage falls off from the inner wall of the flow channel 203. The cleaning mechanism 3 comprises a pipeline 31 and a cleaning medium. The pipeline 31 connects the inlet 201 and the outlet 202 to form a closed circulation loop 6. The cleaning medium flows in the circulation loop 6 and carries the fallen blockage to be discharged from the flow channel 203.

[0056] Optionally, the cleaning medium may be deionized water, compressed air, or a dedicated cleaning solution, the specific choice depending on the nature of the blockage and the material of the inner rod 200. When compressed air is used for cleaning, it cannot remove the blockage well, so a liquid cleaning medium is generally selected for cleaning.

[0057] It is understood that the frequency and force of the knocking assembly 22 can be optimized by adjusting the parameters of the drive assembly 21 to adapt to different degrees of blockage. For example, for mild blockage, a lower frequency and force of knocking can be used; while for severe blockage, the frequency and force of knocking can be increased to enhance the vibration effect.

[0058] The technical solution of the present invention supports the inner rod 200 through a fixing mechanism 1, and the driving assembly 21 drives the knocking assembly 22 to move along the extension direction of the inner rod 200 and knock the inner rod 200. The knocking vibration causes the blockage to be detached from the inner wall of the flow channel 203. The cleaning mechanism 3 drives the cleaning medium to flow within the circulation loop 6 formed by the pipeline 31 and the flow channel 203, thereby driving the detached blockage to be discharged from the flow channel 203 of the inner rod 200. In this way, the blockage in the inner rod 200 can be removed without contacting the inner wall of the inner rod 200, thereby reducing wear on the inner rod 200 and extending the service life of the inner rod 200.

[0059] In one embodiment, see Figure 1 The cleaning mechanism 3 further includes a booster pump 32 and a filter 33. The pipeline 31 sequentially connects the inlet 201, the booster pump 32, the filter 33 and the outlet 202. Among them, the booster pump 32 is used to drive the cleaning medium to flow along the circulation loop 6, and the filter 33 is used to filter the blockage in the cleaning medium.

[0060] In this embodiment, a booster pump 32 is installed on the pipeline 31 near the inlet 201 to provide power for the cleaning medium and ensure that it maintains a stable flow rate in the circulation loop 6. A filter 33 is installed at the outlet 202 to intercept blockages suspended in the cleaning medium and prevent it from re-entering the flow channel 203 of the inner rod 200 and causing secondary blockage.

[0061] Optionally, filter 33 can employ a multi-stage filtration design, first removing large impurities and then adsorbing fine particles to ensure the purity of the cleaning medium. Alternatively, filter 33 can be equipped with an automatic backwash function. When filter 33 detects an excessively high pressure differential, it automatically initiates a backwash process to clear blockages from the filter element, reducing manual maintenance workload and improving the automation level of the equipment.

[0062] It can be understood that the booster pump 32 and the filter 33 can ensure efficient flow and reuse of the cleaning medium, reduce operating costs, and improve the automation level and reliability of the cleaning process.

[0063] In one embodiment, see Figure 1 The cleaning device 100 further includes a pressure detection mechanism 4 , which is disposed at the outlet 202 and electrically connected to the knocking mechanism 2 . The pressure detection mechanism 4 is used to detect the pressure generated by the cleaning medium at the outlet 202 .

[0064] In this embodiment, the cleaning device 100 implements real-time monitoring and intelligent control of the cleaning process by adding a pressure detection mechanism 4. Pressure detection mechanism 4 is installed at outlet 202 and monitors the pressure of the cleaning medium as it is discharged. This pressure value reflects the degree of blockage within flow channel 203 and the effectiveness of the knocking assembly 22. Pressure detection mechanism 4 is electrically connected to knocking mechanism 2 and provides real-time feedback of the pressure signal to the knocking mechanism 2's control system for automatic regulation.

[0065] Optionally, the pressure detection mechanism 4 may use a high-precision pressure sensor, and its measuring range should be reasonably selected according to the working pressure of the cleaning medium to ensure measurement accuracy and reliability.

[0066] In one embodiment, see Figure 1 The cleaning device 100 further includes a control mechanism 5, which is electrically connected to the knocking assembly 22, the pressure detection mechanism 4, and the driving assembly 21. The control mechanism 5 adjusts the knocking frequency of the knocking assembly 22 and the movement state of the driving assembly 21 according to the pressure detected by the pressure detection mechanism 4.

[0067] In this embodiment, the pressure detection mechanism 4 monitors the pressure of the outlet 202 in real time and feeds it back to the control mechanism 5. The control mechanism 5 can judge the degree of blockage according to the pressure, calculate the optimal knocking frequency according to the preset algorithm, and adjust the working parameters of the knocking component 22 accordingly. For example, after knocking, the pressure decreases, indicating that the knocking causes the blockage to fall off. The control mechanism 5 can increase the knocking frequency and enhance the vibration intensity to ensure that the blockage here can fall off completely. On the contrary, if there is no obvious change in pressure, it means that there is no blockage here, then the knocking frequency is reduced to save energy. Among them, the control mechanism 5 can also control the drive component 21 to knock back and forth along the extension direction of the inner rod 200, thereby improving the cleaning effect, and when the pressure does not change significantly, the moving speed can also be appropriately accelerated, otherwise the moving speed can be slowed down.

[0068] Optionally, the control mechanism 5 can integrate an intelligent control unit such as a PLC or a single-chip microcomputer, and write a customized control program to achieve precise control under complex and changeable working conditions.

[0069] Optionally, the control mechanism 5 may also be connected to the booster pump 32 to facilitate adjustment of the pressure of the cleaning medium when it flows into the flow channel 203, thereby improving the control accuracy.

[0070] In one embodiment, see Figure 2 and Figure 3The driving assembly 21 includes a movable base 211 and a support structure 212. The support structure 212 is disposed on the movable base 211 and has a movable cavity 2121 for the inner rod 200 to pass through. The striking assembly 22 is disposed on the support structure 212 and adjacent to the movable cavity 2121. The movable base 211 drives the support structure 212 to move along the extension direction of the inner rod 200.

[0071] In this embodiment, the support structure 212 is mounted on the movable base 211 and is provided with a movable cavity 2121 to accommodate the inner rod 200. The knocking assembly 22 is fixed on the support structure 212, adjacent to the movable cavity 2121, to ensure that the knocking force can be effectively transmitted to the inner rod 200. Under the action of the driving device, the movable base 211 drives the support structure 212 to move linearly along the extension direction of the inner rod 200, so that the knocking assembly 22 performs a comprehensive and uniform knocking coverage on the inner rod 200, ensuring that the blockage is completely loosened. Optionally, the driving device of the movable base 211 can be selected from a screw-nut mechanism, a synchronous belt drive, or a rack and pinion drive, etc., and is selected according to the required moving speed and accuracy requirements.

[0072] In one embodiment, see Figure 2 and Figure 3 The movable base 211 includes a base plate 2111, a plurality of driving members 2112, and a plurality of rollers 2113. The plurality of driving members 2112 are symmetrically arranged on opposite sides of the base plate 2111, and each roller 2113 is connected to the output end of a driving member 2112. The driving members 2112 drive the rollers 2113 to rotate, so that the base plate 2111 drives the movable base 211 to move along the extension direction of the inner rod 200.

[0073] In this embodiment, the movable base 211 is centered around a base plate 2111, with multiple driving members 2112 symmetrically arranged on either side. Each driving member 2112 is connected to a roller 2113. The rotation of the driving members 2112 drives the rollers 2113, which then contact the ground, pushing the movable base 2111 along the extension direction of the inner rod 200.

[0074] Alternatively, the drive member 2112 may be a brushless DC motor with a reduction gearbox to increase torque output. Alternatively, the surface of the roller 2113 may be coated with a high friction coefficient material such as rubber to enhance grip and reduce wear on the outer wall of the inner rod 200.

[0075] It can be understood that the symmetrically distributed driving members 2112 cooperate with the rollers 2113 to provide stable moving power, ensuring that the movable base 211 can move smoothly along the inner rod 200.

[0076] In one embodiment, see Figures 2 to 4The inner wall of the movable cavity 2121 is provided with a plurality of mounting holes 2122. The striking mechanism 2 further includes a plurality of limiting components 23. Each of the mounting holes 2122 is provided with a limiting component 23. Each limiting component 23 is provided with a movable running wheel 231 on a side away from the bottom wall of the mounting hole 2122. The inner rod 200 is inserted into the movable cavity 2121 so that the running wheel 231 is in movable contact with the side wall of the inner rod 200.

[0077] In this embodiment, the inner wall of the movable cavity 2121 is evenly distributed with multiple mounting holes 2122. Each mounting hole 2122 houses a retaining assembly 23 for controlling the position of the inner rod 200 within the movable cavity 2121. The running wheels 231 within the retaining assembly 23 are movable relative to the bottom wall of the mounting holes 2122. When the inner rod 200 passes through the movable cavity 2121, the running wheels 231 closely contact the sidewalls of the inner rod 200, achieving a retaining contact through rolling. This not only prevents radial displacement of the inner rod 200 during cleaning, but also allows the movable base 211 to drive the support structure 212 to slide smoothly along the axial direction of the inner rod 200.

[0078] It can be understood that such a limiting design provides stable support for the inner rod 200 through multi-point contact, preventing the inner rod 200 from vibrating and deviating during the knocking process, ensuring the uniform application of the knocking force, and thus improving the cleaning effect.

[0079] In one embodiment, see Figure 4 and Figure 5 The support structure 212 includes a coaxially arranged first cylinder 2123 and a second cylinder 2124. The first cylinder 2123 is connected to the movable base 211 and defines a first sub-cavity 2125. The second cylinder 2124 is detachably connected to the first cylinder 2123 and defines a second sub-cavity 2126. The first sub-cavity 2125 and the second sub-cavity 2126 cooperate to form the movable cavity 2121. Along the radial direction of the first cylinder 2123, two mounting holes 2122 arranged along a first direction are defined on opposite sides of the first cylinder 2123. Along the radial direction of the second cylinder 2124, two mounting holes 2122 arranged along a second direction are defined on opposite sides of the second cylinder 2124. A stopper assembly 23 is provided in each mounting hole 2122. The first direction and the second direction are arranged at an angle.

[0080] In this embodiment, the support structure 212 includes a coaxially arranged first cylindrical body 2123 and a second cylindrical body 2124. The first cylindrical body 2123 is connected to the movable base 211 and has a first sub-cavity 2125 defined therein. The second cylindrical body 2124 is detachably connected to the first cylindrical body 2123 and has a second sub-cavity 2126 defined therein. The first sub-cavity 2125 and the second sub-cavity 2126 cooperate to form the movable cavity 2121. The first cylindrical body 2123 has mounting holes 2122 arranged along a first direction on both radial sides, while the second cylindrical body 2124 has mounting holes 2122 arranged along a second direction. The two cylindrical bodies form an angled relationship, ensuring that the limiting assembly 23 can limit the inner rod 200 from different directions. Among them, the second cylinder 2124 is rotatably connected to the first cylinder 2123, and a rotation hole 2127 is provided on the second cylinder 2124. When the second cylinder 2124 rotates to the specified position, the second cylinder 2124 is locked on the first cylinder 2123 by using a locking piece, so that the inner rod 200 can be limited from different directions.

[0081] Optionally, the detachable connection between the first cylinder 2123 and the second cylinder 2124 may also be achieved by a threaded connection, a snap connection or a flange connection to facilitate installation and maintenance.

[0082] In one embodiment, see Figure 6 and Figure 7 The limiting assembly 23 further includes a bracket 232, a rotating shaft 233, and an elastic rod 234. The bracket 232 includes a base plate 2321 and side plates 2322 connected to opposite sides of the base plate 2321. The base plate 2321 and the two side plates 2322 enclose a receiving groove 2323. The base plate 2321 is disposed within the mounting hole 2122, and the two side plates 2322 are symmetrically provided with movable holes 2324. The ends of the rotating shaft 233 are movably disposed within the two movable holes 2324. The running wheel 231 is sleeved on the rotating shaft 233, and the running wheel 231 partially protrudes from the notch of the receiving groove 2323. The elastic rod 234 is located within the receiving groove 2323, and the ends of the elastic rod 234 respectively abut against the base plate 2321 and the rotating shaft 233, so that the running wheel 231 elastically abuts against the side wall of the inner rod 200. The inner rod 200 applies pressure to the traveling wheel 231 , and the traveling wheel 231 moves along the extending direction of the moving hole 2324 to compress the elastic rod 234 .

[0083] In this embodiment, the limiting assembly 23 includes a bracket 232, a rotating shaft 233, and an elastic rod 234. The bracket 232 is composed of a base plate 2321 and two side plates 2322, each of which is surrounded by a receiving groove 2323. The base plate 2321 is embedded in the mounting hole 2122. The side plates 2322 are symmetrically provided with movable holes 2324, in which the ends of the rotating shaft 233 are placed. The running wheel 231 is mounted on the rotating shaft 233, partially extending out of the receiving groove 2323 and contacting the outer wall of the inner rod 200. The elastic rod 234 is located in the receiving groove 2323, with its ends respectively abutting the base plate 2321 and the rotating shaft 233. When the inner rod 200 applies pressure to the running wheel 231, the running wheel 231 slides along the movable hole 2324, compressing the elastic rod 234. The reaction force of the elastic rod 234 causes the walking wheel 231 to fit closely with the inner rod 200 to ensure the limiting effect, while allowing the movable seat 211 to move axially along the inner rod 200.

[0084] Alternatively, the elastic rod 234 may be a disc spring or a scroll spring, the characteristic curve of which should match the pressure range of the inner rod 200 to ensure sufficient clamping force. Meanwhile, the material of the running wheel 231 may be polyurethane or nylon to balance wear resistance and shock absorption performance.

[0085] It can be understood that, through the automatic compensation function of the elastic rod 234, the surface profile change of the inner rod 200 is adapted and a stable clamping force is always maintained, so that the position of the inner rod 200 is stable during the movement of the movable seat 211.

[0086] In one embodiment, see Figure 8 The fixing mechanism 1 includes two, each fixing mechanism 1 includes a fixed base 11 and a pressed top seat 12, one end of the pressed top seat 12 is rotatably connected to the fixed base 11, and the other end of the pressed top seat 12 is detachably connected to the fixed base 11, and the fixed base 11 and the pressed top seat 12 are surrounded by a fixing hole 13, and the inner rod 200 is passed through the fixing hole 13.

[0087] In this embodiment, there are two fixing mechanisms 1, which respectively fix the two ends of the inner rod 200. Each fixing mechanism 1 includes a fixed base 11 and a press-fit top seat 12. One end of the press-fit top seat 12 is rotatably connected to the fixed base 11 in a hinged manner, and the other end is connected to the fixed base 11 in a detachable manner, such as a bolt connection or a snap connection. The fixed base 11 and the press-fit top seat 12 together form a fixing hole 13, through which the inner rod 200 passes. This makes it convenient to install and disassemble the inner rod 200. Simply loosen the detachable end of the press-fit top seat 12 to easily remove the inner rod 200, while ensuring the stability of the inner rod 200 during the cleaning process.

[0088] Optionally, a rubber gasket may be added to the contact surface of the fixed base 11 and the press-fit top base 12 to enhance the clamping force and prevent the surface of the inner rod 200 from being scratched. Optionally, the material of the fixing mechanism 1 may be cast iron or aluminum alloy to balance strength and weight.
