Description

Technical Field

[0001] The utility model belongs to the technical field of operation cleaning devices, and in particular relates to an online cleaning device for a calendering roller. Background Art

[0002] During the rolled glass production process, molten glass enters the calender and passes through the gap between two opposing calender rollers, where it is squeezed, stretched, and cooled to form a glass ribbon. However, during the production process, the calender rollers are prone to becoming clogged with foreign matter, such as dust and glass fragments. Especially when hot molten glass passes through the calender rollers, some oxides in the molten glass evaporate and easily adhere to the rollers. Failure to clean the calender rollers promptly can lead to color variations on the surface of the formed glass, surface damage, and excessive thickness variations, seriously affecting the quality of the formed glass.

[0003] To address the above-mentioned problems and improve the pass rate of formed glass, the surface of the calendering roller is currently mostly cleaned manually using a grinding brush. For example, Chinese patent CN206184805U discloses a calendering roller grinding brush, and CN217572356U discloses an easy-to-clean calendering roller grinding brush. Since cleaning needs to be performed close to the calendering roller, to ensure operational safety, the machine is generally stopped for cleaning, which not only affects production progress but also increases manual labor intensity. Some also use cleaning devices for cleaning. For example, Chinese patent CN117816603A discloses a calendering roller cleaning device for a solar glass calender. This device cleans the calendering roller with an electrically driven brush, and cleans and quickly dries the brush through a spray assembly and an air supply assembly. Although this device can replace manual online cleaning of the calendering roller without stopping the machine, the structure of the device is relatively complex, and the contact area between the mechanical brush and the calendering roller during rotation is small, resulting in poor cleaning effect on highly adherent oxides.

[0004] Therefore, it is necessary to design a cleaning device that can clean the calendering roller online with good cleaning effect, so as to improve the quality of the formed glass and ensure the production speed of glass calendering. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an online cleaning device for calendering rollers, so as to solve the technical problem that the current cleaning device for calendering rollers has a poor cleaning effect and to improve the quality of formed glass.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] Example:

[0025] See Figure 1 and Figure 2, an online cleaning device for a calendering roller, comprising a first guide rail 2 arranged on the side of the calendering roller 1 away from the roller gap, the length direction of the first guide rail 2 corresponds to the axial direction of the calendering roller 1, a first slide 3 is slidably connected to the first guide rail 2, and the first guide rail 2 is provided with a first driving member 4 for driving the first slide 3 to slide along the first guide rail 2; a second guide rail 5 perpendicular to the first guide rail 2 is provided on the first slide 3, a second slide 6 is slidably connected to the second guide rail 5, and the second guide rail 5 is provided with a second driving member 7 for driving the second slide 6 to slide along the second guide rail 5; a grinding sheet 8 is provided on the second slide 6, and the grinding surface of the grinding sheet 8 faces the calendering roller 1 and can move with the second slide 6 to abut against the calendering roller 1.

[0026] The online cleaning device for the calendering roller of the present invention, during cleaning, first drives the second slide 6 to move through the second driving member 7, so that the grinding disc 8 is close to the calendering roller 1, and the grinding surface abuts against the surface of the calendering roller 1. As the calendering roller 1 rotates, the grinding disc 8 grinds off foreign matter attached to the surface of the calendering roller 1 within a certain axial range. Then, the first driving member 4 drives the first slide 3 to move, so that the grinding disc 8 abuts against various axial positions of the calendering roller 1. As the calendering roller 1 rotates, the entire surface of the calendering roller 1 is cleaned. The online cleaning device for the calendering roller can clean the calendering roller 1 online. It not only has a simple structure, but also can effectively remove foreign matter attached to the surface of the calendering roller 1 by grinding. It has a good cleaning effect, which is beneficial to improving the quality of the glass formed by the calendering machine 19.

[0027] See Figure 2 Since the rotation speed of the calendering roller 1 is slow, the speed of the grinding plate 8 moving circumferentially relative to the calendering roller 1 is slow, and the grinding effect produced is weak. Therefore, the calendering roller online cleaning device is also provided with a second motor 9 on the second slide 6. The axial direction of the second motor 9 corresponds to the length direction of the second guide rail 5. The output shaft of the second motor 9 faces the calendering roller 1 and is vertically connected to the grinding plate 8, so that the grinding plate 8 rotates and grinds the surface of the calendering roller 1; in this embodiment, the first driving member 4 drives the first slide 3 to slide along the first guide rail 2 at a speed of 3-5 times the linear speed of the calendering roller 1, and the second motor 9 drives the grinding plate 8 to rotate at a speed of 9-11 times, preferably 10 times, the linear speed of the calendering roller 1; in this way, the second motor 9 drives the grinding plate 8 to rotate at a high speed, which can produce a better grinding effect, and cooperates with the first slide 3 to slide and move quickly along the first guide rail 2 to grind foreign matter on the surface of the calendering roller 1 faster and better.

[0028] See Figure 2The output shaft of the second motor 9 is vertically connected to the connecting plate 10, and the grinding disc 8 is detachably connected to the connecting plate 10; in this way, the output shaft of the second motor 9 is detachably connected to the grinding disc 8 through the connecting plate 10, so that the grinding disc 8 can be replaced regularly to ensure the cleaning effect of the calendering roller online cleaning device on foreign matter on the surface of the calendering roller 1; during implementation, the grinding disc 8 is provided with a circle of bolts near the center to be detachably connected to the connecting plate 10, and the center line of the grinding disc 8 should be higher or lower than the axis of the calendering roller 1 so that part of the grinding disc 8 abuts against the calendering roller 1 to exert a grinding effect.

[0029] See Figure 2 The output shaft of the second motor 9 is coaxially connected to the transmission shaft 12 through a coupling 11, and the grinding disc 8 is connected to the end of the transmission shaft 12 for synchronous rotation; in this way, the output shaft of the motor is extended by the transmission shaft 12, and the distance between the second motor 9 and the calendering roller 1 is increased, thereby reducing the influence of the heat radiation of the glass liquid on the second motor 9, which is conducive to improving the stability of the operation of the second motor 9.

[0030] See Figure 2 A transmission bracket 13 rotatably connected to the transmission shaft 12 is fixedly provided on the second slide 6; in this way, the second slide 6 supports the transmission shaft 12 through the transmission bracket 13 to improve the stability of the rotation of the transmission shaft 12, so that the grinding plate 8 produces a stable grinding effect on the calendering roller 1.

[0031] See Figure 2 Thus, during operation, circulating cooling water is introduced into the water-cooled motor casing 14 to further reduce the temperature of the second motor 9 to avoid overheating and shutdown of the second motor 9 or even burning.

[0032] See Figure 1 The first driving member 4 is a ball screw, the first slide 3 is connected to the nut of the ball screw, and a first motor 15 is provided at one end of the first guide rail 2, and the first motor 15 is connected to the screw transmission of the ball screw; in this way, during cleaning, the first motor 15 drives the first slide 3 to slide along the first guide rail 2 through the ball screw, so that the grinding plate 8 moves and abuts against various axial positions of the calendering roller 1 in turn, and the cleaning of the entire surface of the calendering roller 1 is completed as the calendering roller 1 rotates; compared with driving members such as cylinders and traction machines, the ball screw is used as the driving member and driven by a motor, which has more flexible and better stability in controlling the speed of the grinding plate 8, and has a certain self-locking ability, which is convenient for locking the position of the grinding plate 8 in conjunction with the motor self-locking.

[0033] See Figure 1A reducer 16 is connected to the first motor 15 and the screw of the ball screw; in this way, the first motor 15 is connected to the ball screw through the reducer 16, which improves the moving load capacity and moving stability of the first slide 3, so that the grinding plate 8 can overcome the friction and move axially along the calendering roller 1, thereby completing the cleaning of the entire surface of the calendering roller 1 as the calendering roller 1 rotates.

[0034] See Figure 2 The second driving member 7 is a ball screw, the second slide 6 is connected to the nut of the ball screw, and a hand wheel 17 is provided at the end of the second guide rail 5 away from the calendering roller 1, and the hand wheel 17 is connected to the screw transmission of the ball screw; in this way, when cleaning, the second slide 6 is first driven to move by the ball screw, so that the grinding sheet 8 is close to and abuts against the calendering roller 1. Compared with driving members such as cylinders and traction machines, the ball screw is used as the driving member, and the control of the moving distance of the grinding sheet 8 is more precise, so that the grinding surface and the surface of the calendering roller 1 are in an appropriate contact state through manual adjustment by the hand wheel 17, while ensuring the grinding and cleaning effect, the influence on the rotation and extrusion of the calendering roller 1 to form the glass liquid is reduced as much as possible.

[0035] See Figure 1 The first guide rail 2 is fixedly connected to the calender 19 through the support bracket 18; in this way, the calender roller online cleaning device is integratedly installed on the corresponding calender 19 through the support bracket 18, without occupying the ground to set up additional installation points and mounting frames, which is conducive to improving the practicality of the calender roller online cleaning device.

[0036] 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. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution of the present invention should be included in the scope of the claims of the present invention.
