Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of calendering rolls of calendering machines, in particular to a tension regulation device and method for nanocrystalline glass calendering production. BACKGROUND

[0002] In marine environmental monitoring, the physical and chemical properties and biological components of water bodies show significant differences with depth. Obtaining water samples at multiple depths is the core basis for pollution tracing and ecological assessment. Currently, a ship-mounted hydrological investigation winch is used to drive a sampling assembly to sample seawater.

[0003] There are many existing technologies for sampling assemblies, such as: Chinese patent CN120192076A discloses a calendering device and a glass production line, relating to the technical field of glass production. The calendering device includes a rack, a calendering pair of rollers, a first cooling roller, a first deflection roller, and a transition roller set. The calendering pair of rollers and the transition roller set are both installed on the rack, and the calendering pair of rollers are provided with a pair of roller gaps. The first cooling roller, the first deflection roller, and the transition roller set are arranged in sequence and parallel to each other. The first cooling roller and the transition roller set are both arranged on the lower side of the glass ribbon, and the first deflection roller is arranged on the upper side of the glass ribbon. The glass ribbon passing through the first cooling roller travels to the first deflection roller at a first preset angle, which is the included angle between the glass ribbon and the horizontal plane, and the range of the first preset angle is 95 to 105 degrees. The calendering device provided by the application can prevent the edge of the glass ribbon from bending and deforming, avoid the formation of wavy edges on both sides of the glass ribbon, improve the flatness of the glass ribbon, and ensure the quality of glass forming.

[0004] However, there are still some problems in actual use: 1. During the nanocrystalline glass calendering production process, if the roller body is overheated, thermal deformation of "middle drum, both ends thin" may occur, resulting in uneven gap between the upper and lower rollers, and the calendered glass ribbon cannot meet the high-precision requirements. 2. During the nanocrystalline glass calendering process, the nanocrystalline glass is extremely sensitive to tension fluctuations due to its nanocrystalline phase structure. During the calendering process, the glass ribbon tension needs to be quickly and accurately compensated according to dynamic conditions such as material viscosity changes, calendering speed adjustments, and cooling rate fluctuations. However, existing devices rely on manual adjustment of tension parameters (such as roller spacing, edge tension, and speed difference), which is not only tedious to operate and has a lagging response, but also affects production efficiency.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0023] The tension control device and method for nanocrystalline glass calendering production are based on Figures 1-8As shown, including the frame 100, the frame 100 surface is provided with the fixed roller 11, the fixed roller 11 is provided with the tension control assembly, the tension control assembly includes the cylinder 13 arranged at the top of the frame 100, the end of the cylinder 13 is provided with the moving seat plate 14, the moving seat plate 14 is provided with the dynamic roller 12, the fixed roller 11 and the dynamic roller 12 are driven by the motor, the distance between the fixed roller 11 and the dynamic roller 12 is controlled to accurately adjust the tension of the pressure melt, the frame 100 is provided with the cooling pool 200 below, the cooling pool 200 is filled with cooling liquid, the fixed roller 11 and the dynamic roller 12 are respectively provided with the cooling assembly 300 at the bottom and the top, the cooling assembly 300 is used for cooling the surface of the fixed roller 11 and the dynamic roller 12, the cooling assembly 300 is provided with the fitting assembly 400 at the bottom, the fitting assembly 400 maintains the fitting of the cooling assembly 300 with the surface of the fixed roller 11 and the dynamic roller 12 during the calendering operation, the cooling pool 200 is provided with the cooling assembly 500, the cooling assembly 500 is used for rapidly cooling the cooling liquid flowing through the cooling assembly 300 to recycle.

[0024] In the process of calendering nanocrystalline glass, if the roller body is overheated, thermal deformation of "middle drum, both ends thin" will occur, which will cause uneven gap between the upper and lower rollers, and the calendered glass ribbon cannot meet the high precision requirement. Therefore, the cooling assembly 300 includes the cooling roller 31 arranged at the bottom of the fixed roller 11 and the top of the dynamic roller 12, the cooling roller 31 is provided with the water groove 32 inside, the water groove 32 is provided with the water inlet 33 and the water outlet on both sides, the water inlet 33 is screw-shaped, and the cooling liquid increases the contact area when passing through the water inlet 33. In the production process, when the nanocrystalline glass melt is calendered by the fixed roller 11 and the dynamic roller 12, the fixed roller 11 and the dynamic roller 12 rotate relatively, because the surface temperature of the nanocrystalline glass melt is high, the fixed roller 11 and the dynamic roller 12 are fitted at the bottom of the fixed roller 11 and the top of the dynamic roller 12 through the water inlet 33, the temperature is conducted to the surface of the cooling roller 31, the cooling liquid is injected into the water inlet 33, the cooling liquid moves through the water groove 32 arranged inside the cooling roller 31, the water groove 32 is screw-shaped, so that more cooling liquid flows through the inside of the cooling roller 31, which can quickly take away the heat, thereby ensuring the production precision of nanocrystalline glass.

[0025] In order to reduce water waste when the cooling liquid cools the surface of the fixed roller 11 and the movable roller 12 through the cooling roller 31, the cooling liquid in the cooling pool 200 is recycled. When impurity particles are adsorbed in the circulating liquid during use, the impurity accumulation will reduce the flow passage cross-sectional area, resulting in reduced cooling liquid flow, slow flow rate, and reduced heat dissipation capacity. The accumulation will form a "heat insulation layer" to hinder the transfer of heat from the roller body to the cooling liquid, causing the roller surface temperature to rise and be unevenly distributed, affecting heat dissipation. Therefore, the water inlet 33 is a three-way pipe, and the filter plate 34 is arranged inside the water inlet 33. The filter plate 34 is used to block impurities in the cooling liquid, and the impurities are filtered through the filter plate 34, so that the impurities cannot enter the inside of the cooling roller 31, thereby avoiding the accumulation of impurities affecting the heat exchange between the cooling liquid and the cooling roller 31, and improving the heat dissipation effect of the cooling roller 31.

[0026] When there is too much impurity in the cooling liquid, the surface of the filter plate 34 is easily blocked, which needs to be replaced, affecting production efficiency. When the water flow rate is high, the water flow impacts the inner wall of the water tank 32, which easily causes the cooling roller 31 to vibrate, affecting the precision of the nanocrystalline glass calendering production. Therefore, the support frame is arranged on the back of the filter plate 34, and the fan blade 35 is rotatably arranged on the surface of the support frame. The cooling liquid impacts the fan blade 35 when passing through the water inlet 33 to make it rotate. The end of the fan blade 35 is provided with a connecting shaft, and the connecting shaft penetrates the filter plate 34 and is provided with a scraper 36 at the end. The scraper 36 is attached to the outer surface of the filter plate 34. Since the fan blade 35 is rotatably arranged on the surface of the support frame, when the water flow impacts the fan blade 35 through the water inlet 33, the fan blade 35 rotates under the impact force, reducing the kinetic energy of the water flow, avoiding the vibration of the cooling roller 31 caused by too strong water flow kinetic energy, and ensuring the stability during production. At the same time, the scraper 36 is scraped on the surface of the filter plate 34 during the rotation of the fan blade 35, so that the impurities adhering to the surface of the filter plate 34 fall into the three-way pipe, and the scraper 36 is automatically cleaned, thereby improving the production efficiency.

[0027] During the nanocrystalline glass calendering process, the tension needs to be quickly adjusted. The cooling pool 200 is provided with a water pump 37 on one side. The output end of the water pump 37 is provided with a tapping pipe 38 connected to the end of the water inlet 33. The tapping pipe 38 and the water inlet 33 are connected through a rubber connecting sleeve 39. By controlling the piston rod at the end of the air cylinder 13 to drive the moving seat plate 14 to move downward in the vertical direction, the moving seat plate 14 drives the fixed roller 11 and the cooling roller 31 to move downward. During the downward movement of the cooling roller 31, the position between the water inlet 33 provided at the end of the cooling roller 31 and the tapping pipe 38 is offset, and the displacement is compensated by the rubber connecting sleeve 39, thereby facilitating the quick adjustment of the tension.

[0028] In the production process, in order to ensure that the cooling roller 31 is always in contact with the fixed roller 11, the bonding assembly 400 includes a column barrel 41 located on one side of the frame 100. A slide rod 42 is slidably provided on the inner wall of the column barrel 41. A compression spring 43 is provided between the column barrel 41 and the slide rod 42. An extension block 44 is provided at the top of the slide rod 42. The extension block 44 is fixed on both sides of the bottom of the cooling roller 31. The extension block 44 at the top of the slide rod 42 is fixed on the bottom side of the cooling roller 31. The support force of the compression spring 43 makes the slide rod 42 receive a vertical upward support force, so that the surface of the water inlet 33 is in contact with the bottom of the fixed roller 11. During the flow of coolant inside the cooling roller 31, it is kept in contact with the fixed roller 11, thereby improving the heat dissipation effect.

[0029] Considering that the coolant flows from the outlet of the cooling roller 31 into the cooling pool 200, in order to quickly cool and recycle it, the cooling assembly 500 includes a servo motor 51 located on one side of the cooling pool 200. The output shaft of the servo motor 51 passes through the cooling pool 200 and has a lead screw 52 at its end. The surface of the lead screw 52 is provided with a ramp plate 53. When the lead screw 52 rotates, it drives the ramp plate 53 to move horizontally on its surface. The top of the lead screw 52 is higher than the plane of the coolant contained in the cooling pool 200. The bottom of the ramp plate 53 is provided with a connecting rod 54, and the bottom of the connecting rod 54 is provided with a roller frame 55. The cooling pool 200 is equipped with rollers inside the roller frame 55. When the rollers inside the roller frame 55 move, they are in close contact with the bottom of the cooling pool 200. Extension rods are provided on both sides of the rollers. Stirring fans 56 are provided at the ends of the extension rods. The output of the control servo motor 51 drives the lead screw 52 to rotate. When the lead screw 52 rotates, the ramp plate 53 moves horizontally. When the ramp plate 53 moves, it pushes the coolant over its surface and exchanges heat with the air. At the same time, during the movement of the ramp plate 53, it drives the rollers inside the roller frame 55 to move in contact with the bottom of the cooling pool 200, so that the stirring fans 56 provided on both sides of the rollers rotate, which accelerates the heat dissipation of the coolant and improves the heat dissipation efficiency.

[0030] In practical use, during the production process, when the molten microcrystalline glass is rolled through the fixed roller 11 and the moving roller 12, the fixed roller 11 and the moving roller 12 rotate relative to each other. Since the surface temperature of the molten microcrystalline glass is high, it adheres to the bottom of the fixed roller 11 and the top of the moving roller 12 through the water inlet 33, and the temperature is conducted to the surface of the cooling roller 31. By injecting coolant into the water inlet 33, the coolant passes through the water tank 32 opened inside the cooling roller 31. Since the water tank 32 is spiral, more coolant flows through the interior of the cooling roller 31, which can quickly remove the heat and thus ensure the production accuracy of microcrystalline glass rolling. Impurities are filtered by the filter plate 34, preventing them from entering the interior of the cooling roller 31. This avoids the accumulation of impurities, which would affect the heat exchange between the coolant and the cooling roller 31, thereby improving the heat dissipation effect of the cooling roller 31. When the water flow impacts the fan blade 35 through the water inlet 33, the fan blade 35 is impacted and rotated, the kinetic energy of the water flow is reduced, the vibration of the cooling roller 31 caused by the too strong kinetic energy of the water flow is avoided, the stability in the production process is ensured, meanwhile, the scraper 36 is scraped on the surface of the filter plate 34 in the rotating process of the fan blade 35, the impurities adhered to the surface of the filter plate 34 fall into the tee pipe, the scraper 36 is cleaned automatically, and the production efficiency is improved; By controlling the piston rod at the end of the air cylinder 13 to drive the moving seat plate 14 to move downward in the vertical direction, the moving seat plate 14 drives the fixed roller 11 and the cooling roller 31 to move downward when moving, the position offset between the water inlet 33 provided at the end of the cooling roller 31 and the tapping pipe 38 is compensated by the rubber connecting sleeve 39, so that the tension can be quickly adjusted. The servo motor 51 drives the screw rod 52 to rotate, the slope plate 53 moves horizontally when the screw rod 52 rotates, the cooling liquid is pushed to pass through the surface of the slope plate 53 and exchange heat with air when the slope plate 53 moves, meanwhile, the rollers inside the roller frame 55 move while adhering to the bottom of the cooling pool 200 in the moving process of the slope plate 53, the stirring fans 56 provided on the two sides of the rollers rotate, the heat dissipation of the cooling liquid is accelerated, and the heat dissipation efficiency is improved.

[0031] The second purpose of the application is to provide a nano microcrystalline glass calendering production tension control method, comprising the nano microcrystalline glass calendering production tension control device of any one of the above, comprising the following steps: S1, when the glass melt is calendered by the fixed roller 11 and the movable roller 12, the fixed roller 11 and the movable roller 12 rotate relative to each other, and since the surface temperature of the microcrystalline glass melt is high, the 3 is adhered to the bottom of the fixed roller 11 and the top of the movable roller 12, and the surface of the fixed roller 11 is cooled by the 3; S2, when the cooling assembly 300 adheres to the surface of the fixed roller 11, the adhering assembly 400 pushes the cooling assembly 300 to adhere to the surfaces of the fixed roller 11 and the movable roller 12, so as to avoid the cooling assembly 300 from moving away from the surface of the fixed roller 11; S3, when the cooling liquid flows into the cooling pool 200 through the cooling assembly 300, the cooling assembly 500 pushes the cooling liquid to accelerate the heat exchange between the cooling liquid and air.
