Description

Technical Field

[0001] The invention belongs to the technical field of operating cleaning devices, and in particular relates to an online cleaning structure for the surface of a calendering roller. Background Art

[0002] Ultra-thin microcrystalline glass is usually formed by calendering. Calendering is to introduce molten glass liquid into the calendering machine, so that the glass liquid passes through the roller gap between two parallel calendering rollers, and is squeezed, stretched, and cooled by the calendering rollers to obtain a ribbon of glass of the required thickness. During the calendering process, the calendering roller is continuously subjected to high temperature and high-strength extrusion force. Not only are foreign objects such as dust and glass debris easily attached to the roller surface, but also when the high-temperature glass liquid passes through the calendering roller, some oxides in the glass liquid are easily attached to the roller surface after volatilization. These attachments will increase the roughness of the roller surface, resulting in uneven cooling effect of the roller surface and uneven distribution of glass liquid on the roller surface. If the calendering roller is not cleaned in time, the formed glass will have excessive thickness difference, warping, cold cracking and surface color difference. If the roller surface coating and oxide fall off, it is also easy to cause roller damage and poor finish on the glass plate surface, and even the risk of sticking to the roller, which will not only affect the quality of the formed glass, but also reduce the service life of the calendering roller.

[0003] In order to address the above problems and improve the qualified rate of formed glass, currently, the calendering rollers are replaced regularly for cleaning or the roller surface is cleaned manually with a grinding brush, such as a calendering roller grinding brush disclosed in Chinese patent CN206184805U and an easy-to-clean calendering roller grinding brush disclosed in CN217572356U. However, regular replacement of calendering rollers is troublesome and time-consuming, and manual cleaning of the roller surface needs to be done close to the calendering roller. In order to ensure safe operation, the machine needs to be stopped for cleaning, which not only affects the production progress but also has high labor intensity. Therefore, it is necessary to design a cleaning structure that can clean the calendering roller online and has a good cleaning effect, so as to improve the quality of calendered glass and ensure the production efficiency of glass calendering.

DETAILED DESCRIPTION

[0026] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Example:

[0029] The online cleaning structure of the surface of the calendering roller 4 of the present invention is provided with a support frame 1 connected to a cleaning scraper 3 as a roller surface cleaning tool, which replaces a manually held cleaning tool to reduce the labor intensity of manual labor and improve the safety of roller surface cleaning; the support frame 1 is driven and connected to the cleaning scraper 3 through an adjustment mechanism 2. When the roller surface is cleaned regularly, the adjustment mechanism 2 is used to drive the cleaning scraper 3 to move close to the roller surface so that the cleaning scraper 3 is kept in contact with the roller surface. As the calendering roller 4 rotates, the cleaning scraper 3 scrapes off the attachments on the roller surface, and then the cleaning scraper 3 is separated from the roller surface to complete the cleaning. At the same time, it can also prevent the cleaning scraper 3 from being in contact with the roller surface for a long time. The roller surfaces abut against each other, causing roller surface wear and affecting calendering production; the length direction of the cleaning scraper 3 is set to correspond to the axial direction of the calendering roller 4 and the length is matched to ensure that as the calendering roller 4 rotates, the cleaning scraper 3 can complete the cleaning of the entire roller surface; the online cleaning structure of the calendering roller 4 surface of the present invention can not only clean the calendering roller 4 online without affecting the production progress, but also effectively remove the attachments on the roller surface through the rotation of the cleaning scraper 3 and the calendering roller 4, and has a good cleaning effect, which can effectively solve the current time-consuming and laborious problem of cleaning the calendering roller 4, and achieve the effect of improving the calendering quality and production efficiency.

[0030] See also Figure 1 and Figure 2 A plurality of nozzles 6 are provided on the support frame 1 at intervals along the axial direction of the calendering roller 4. The nozzles 6 are located on the side of the calendering roller 4 away from the roller gap 5. The water outlet of the nozzles 6 faces the calendering roller 4, and the water outlet of the nozzles 6 is higher than the cleaning scraper 3.

[0031] In this way, when cleaning the roller surface, cleaning water is introduced into the nozzle 6 and sprayed toward the calendering roller 4 through the water outlet to achieve flushing. Multiple nozzles 6 are arranged at intervals along the axial direction of the calendering roller 4 so as to flush various axial positions of the calendering roller 4; the cleaning scraper 3 is arranged on the side of the calendering roller 4 away from the roller gap 5 to avoid interference with the calendering production, and the nozzle 6 is arranged on the side of the calendering roller 4 away from the roller gap 5, and the nozzle 6 is arranged on the side of the cleaning scraper 3 away from the roller gap 5 to avoid direct contact of the cleaning water with the glass liquid passing through the roller gap 5, thereby affecting the calendering molding; the water outlet of the nozzle 6 is higher than the cleaning scraper 3, and the water sprayed is The position on the roller surface is higher than the position of the cleaning scraper 3 on the roller surface, which not only allows the attachments scraped off by the cleaning scraper 3 to be separated from the calendering roller 4 with the water flow to avoid the attachments from splashing everywhere, but also due to the difference in the thermal expansion and contraction characteristics of the roller surface and the attachments thereon, before the roller surface reaches the cleaning scraper 3, the roller surface and the attachments thereon are washed and cooled, which can loosen the attachments on the roller surface so as to cooperate with the cleaning scraper 3 to scrape off the attachments. The roller surface is washed and cooled, which can also avoid the temperature of the calendering roller 4 due to friction during cleaning. It prevents the calendering roller 4 from sticking to the roller after a long time, which is beneficial to glass calendering molding.

[0032] See also Figure 1 and Figure 2 The support frame 1 includes a support seat 7 and a mounting plate 8. The support seat 7 is fixedly set on the ground or calendering equipment and is provided with a lifting mechanism 9. The support seat 7 is connected to the mounting plate 8 through the lifting mechanism 9. The adjustment mechanism 2 and the nozzle 6 are arranged on the mounting plate 8. The lifting mechanism 9 is used to drive the mounting plate 8 to move vertically to adjust the position of the cleaning scraper 3 and the nozzle 6 acting on the roller surface.

[0033] In this way, the adjustment mechanism 2 and the nozzle 6 are set on the mounting plate 8, and the lifting mechanism 9 drives the mounting plate 8 to move vertically, so that the positions of the cleaning scraper 3 and the nozzle 6 acting on the roller surface can be adjusted by the lifting mechanism 9, so that the online cleaning structure of the surface of the calendering roller 4 can be used more flexibly and can better adapt to the cleaning needs of the calendering roller 4 under various working conditions.

[0034] See also Figure 2 and Figure 3 The length direction of the mounting plate 8 corresponds to the axial direction of the calendering roller 4. The mounting plate 8 is located on the side of the calendering roller 4 away from the roller gap 5. The mounting plate 8 has a clearance opening 16 on the side facing the calendering roller 4, and the cleaning scraper 3 is located in the clearance opening 16; the adjustment mechanism 2 includes a slide groove 17, a protrusion 18 and a locking piece 19. The slide groove 17 is arranged at the two end surfaces of the clearance opening 16, and the protrusion 18 is arranged at both ends of the cleaning scraper 3. The protrusion 18 is located in the slide groove 17 at the corresponding end and can move along the slide groove 17 to adjust the distance between the cleaning scraper 3 and the roller surface. The locking piece 19 is arranged on the cleaning scraper 3 or the mounting plate 8, and can lock and release the movement of the protrusion 18.

[0035] In this way, when the lock is released by the locking piece 19, the cleaning scraper 3 can move in its own width direction in the clearance opening 16 through the cooperation of the protrusion 18 and the slide groove 17, and adjust the distance between the cleaning scraper 3 and the roller surface. After the movement is completed, the locking piece 19 locks the movement of the protrusion 18 to fix the position of the cleaning scraper 3; when cleaning the roller surface regularly, not only can the cleaning scraper 3 be kept in contact with the roller surface to cooperate with the rotation of the calender roller 4 to scrape off the attachments on the roller surface, but the abutment force can also be flexibly adjusted to meet different cleaning needs.

[0036] See also Figure 2 and Figure 3 The slide groove 17 penetrates the mounting plate 8 axially along the calendering roller 4 , the raised portion 18 is in the shape of a round rod and extends axially along the calendering roller 4 , the slider extends to the outside of the mounting plate 8 through the slide groove 17 and is threadedly connected with a locking nut 20 , and the locking nut 20 serves as the locking member 19 .

[0037] In this way, when the locking nut 20 is pressed against the end surface of the mounting plate 8, the movement of the protrusion 18 is locked. After the locking nut 20 at either end is loosened, the movement lock of the protrusion 18 is released, and the cleaning scraper 3 can not only move in the width direction of itself through the cooperation of the protrusion 18 and the slide groove 17 in the clearance opening 16, but also the protrusion 18 is designed to be a round rod, so that the protrusion 18 can also be used as a rotating shaft for the cleaning scraper 3 to rotate; not only can the distance between the cleaning scraper 3 and the roller surface be adjusted, but also the angle of the cleaning scraper 3 can be adjusted, so that the adjustment of the cleaning scraper 3 is more flexible, and the cooperation of the two can change the position where the cleaning scraper 3 abuts against the roller surface, so as to meet various usage requirements, which is conducive to improving the practicality of the online cleaning structure of the surface of the calender roller 4; in this embodiment, in order to facilitate the movement and rotation of the cleaning scraper 3 through the protrusion 18 after loosening the locking nut 20, the end of the protrusion 18 is also coaxially connected with a bolt 21 as a handle 22.

[0038] See also Figure 2 and Figure 3 The length direction of the mounting plate 8 corresponds to the axial direction of the calendering roller 4. The mounting plate 8 has a water supply channel 10 extending along the axial direction of the calendering roller 4. The water inlet of the nozzle 6 is connected to the water supply channel 10. One end of the water supply channel 10 extends to the end face of the mounting plate 8 and is connected to a water pressure valve 11 for connecting a water supply pipe and adjusting the water pressure.

[0039] In this way, the mounting plate 8 is connected to each nozzle 6 through the water supply channel 10 therein, without the need for additional pipelines, making the structure simpler and more reliable. A water pressure valve 11 connected to the water supply channel 10 is provided on the end face of the mounting plate 8 and is used to connect to the water supply pipe so that the water pressure of the water spray can be adjusted through the water pressure valve 11 according to actual working conditions and cleaning requirements.

[0040] See also Figure 1 and Figure 2The length direction of the mounting plate 8 corresponds to the axial direction of the calendering roller 4. There are two support seats 7 and they are spaced apart along the axial direction of the calendering roller 4. The lifting mechanism 9 includes a screw rod 12 which is vertically arranged on the support seat 7 and can rotate. The screw rod 12 vertically penetrates the mounting plate 8 and is threadedly connected. One end of the screw rod 12 is connected to a driving member for synchronous rotation. In this embodiment, the driving member is a handle wheel 13.

[0041] In this way, the screw rod 12 rotatably connected to the support seat 7 and the mounting plate 8 threadedly connected to the screw rod 12 and penetrated by the two screw rods 12 to limit rotation constitute a screw drive. The rotation of the screw rods 12 on the two support seats 7 can move the mounting plate 8 in the vertical direction. A handle wheel 13 is provided to allow the screw rod 12 to be rotated by hand.

[0042] See also Figure 1 and Figure 2 The two support seats 7 are respectively close to the two ends of the mounting plate 8. The support seat 7 includes two support plates 14 that are vertically spaced and the spacing is greater than the thickness of the support plate 14. The end of the mounting plate 8 is located between the two support plates 14 of the support seat 7. The screw rod 12 vertically penetrates the support plate 14 and can rotate and vertically slide relative to the support plate 14. The driving member is located at the upper end of the screw rod 12 and abuts against the upper support plate 14.

[0043] In this way, the two support plates 14 of the support seat 7 are respectively located on the vertical sides of the mounting plate 8, which not only limits the range of vertical movement of the mounting plate 8, but also prevents the mounting plate 8 from falling; the screw rod 12 movably penetrates the two support plates 14 of the support seat 7, and abuts against the upper support plate 14 through the handle wheel 13 to maintain the vertical position. When the adjustment mechanism 2, nozzle 6 and cleaning scraper 3 on the mounting plate 8 need maintenance or replacement, they can be pressed to keep the vertical position of the mounting plate 8 unchanged, so that the rotating screw rod 12 moves upward and separates from the mounting plate 8, and finally the mounting plate 8 is removed from the support seat 7, so that the online cleaning structure on the surface of the calendering roller 4 is convenient for loading and unloading and maintenance, which is conducive to improving its practicality.

[0044] See also Figure 1 and Figure 2 The calender roller surface online cleaning structure also includes two bearing seats 15 arranged at a transverse interval, the calender roller 4 is rotatably connected between the two bearing seats 15, and the support plate 14 is protruded and formed on the side of the bearing seat 15 away from the roller gap 5.

[0045] In this way, the support seat 7 of the support frame 1 is integrated into the bearing seat 15 of the calendering structure itself, and the support frame 1 does not need an additional support structure, which is beneficial to improving the practicality of the online cleaning structure of the surface of the calendering roller 4.

[0046] See also Figure 2 and Figure 3In the width direction of the cleaning blade 3 , the thickness of the cleaning blade 3 decreases from the side away from the calendering roller 4 to the side close to the calendering roller 4 and a cutting edge 23 is formed on the side close to the calendering roller 4 .

[0047] In this way, the cleaning scraper 3 is used to form a cutting edge 23 on the side that abuts against the roller surface, which can improve the ability of the cleaning scraper 3 to scrape off the attachments from the circular roller surface, reduce the possibility of friction between the cleaning scraper 3 and the roller surface and causing the attachments to be further compressed, which is beneficial to improving the cleaning effect of the online cleaning structure on the surface of the calender roller 4.

[0048] See also Figure 1 and Figure 2 A slag receiving groove 24 with its mouth facing upward is provided directly below the cleaning scraper 3. The slag receiving groove 24 is detachably connected to the support seat 7. The length direction of the slag receiving groove 24 corresponds to the axial direction of the calendering roller 4 and the length matches. The slag receiving groove 24 partially extends to the bottom of the calendering roller 4 in its own width direction.

[0049] In this way, a slag receiving groove 24 is set under the calendering roller 4 and the cleaning scraper 3 to facilitate the collection of scraped attachments. During implementation, the slag receiving groove 24 can be located between the two support seats 7, and a transversely extending slide groove 17 is opened on the opposite sides of the two support seats 7 so that the two ends of the slag receiving groove 24 can be slidably matched with the corresponding side slide grooves 17. The opposite side surfaces of the two support seats 7 can also be raised to form a supporting portion, and the slag receiving groove 24 can be directly placed on the supporting portion.

[0050] In this embodiment, D represents the diameter of the calendering roller and r represents the coating thickness of the roller surface. In the initial state, the cleaning scraper 3 and the axis of the calendering roller 4 are at the same height, the cleaning scraper 3 can be raised and lowered within a range of height H=D / 2, the width of the cleaning scraper 3 d1=D / 2, the adjustment mechanism 2 can adjust the moving distance of the cleaning scraper 3 d2≤D / 2+r, and the rotatable angle α≤90°; the position of the nozzle 6 on the mounting plate 8 should satisfy that when the nozzle 6 is in contact with the cleaning scraper 3 and the roller surface, the distance between the nozzle 6 and the roller surface d=D.

[0051] In order to verify the use effect of the online cleaning structure for the surface of the calender roller of the present invention, a comparative test was conducted between a calender mechanism equipped with the cleaning structure and a calender mechanism not equipped with the cleaning structure, and statistics were made on the life of the calender roller, the probability of abnormality of the calender roller, the use cost of the calender roller and the glass yield rate, and the results were analyzed. The statistical data are shown in the following table:

[0052]

[0053] Result analysis: According to the comparative analysis of the experimental data obtained before and after using the cleaning structure above, it can be seen that after using the cleaning structure, compared with not using the cleaning structure, 1) the online service life of the calendering roller is increased by about 3.5 times, which indirectly increases the output and reduces the frequency of roller replacement, 2) the yield rate of glass (i.e., glass quality) is increased by about 5%, 3) the probability (frequency) of abnormalities of the calendering roller (roller replacement, roller sticking, surface oxidation, chromium loss, etc.) is reduced by 2%-3%, 4) the cost of using the calendering roller is indirectly reduced due to the increase in the service life of the calendering roller and the reduction in the replacement frequency; in summary, through the above data analysis, the use of the cleaning structure of the present invention can effectively improve the stability and yield rate of microcrystalline ultra-thin glass production, and extend the service life and use cost of the calendering roller.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Those skilled in the art should understand that those modifications or equivalent substitutions of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution should be included in the scope of the claims of the present invention.
