Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a novel cooling and cleaning device for grinding rollers. Background Art

[0002] With the development of technology, the operation speed of aluminum foil rolling mills is getting faster and faster, and the efficiency of aluminum foil production is getting higher and higher, so the surface quality requirements of aluminum foil are also getting higher and higher. Aluminum shavings will be generated during the rolling process of aluminum foil, and the aluminum shavings will cause bright lines to appear on the roller surface of the support roller. In order to deal with the problem of aluminum powder and bright lines in a short time, the factory will pull the support rollers out of the rolling mill arch and use the support roller grinding device to grind the upper and lower support rollers. In the process of grinding the support rollers with sandpaper, heat and iron shavings will be generated. At this time, rolling oil is needed to cool and clean the support rollers being ground.

[0003] The current method is usually to cool and clean the rollers manually with a rolling oil spray gun. Since the grinding device reciprocates between the operating side and the driving side of the support roller, the efficiency of cooling and cleaning the rollers manually with a rolling oil spray gun is low, and the grinding process lasts a long time and consumes a lot of energy. Utility Model Content

[0004] The purpose of the utility model is to provide a novel cooling and cleaning device for grinding rolling rollers, which can automatically cool and clean the support rollers when the support rollers are ground, does not require manual intervention, saves manpower and improves the efficiency of cooling and cleaning.

[0005] To achieve the above-mentioned purpose, the solution of the utility model is: a new cooling and cleaning device for grinding rolling mill rolls, comprising a support frame, on which are provided at least two spray beams extending along the length direction of the support roll, wherein the spray beam has a cavity, and an oil inlet pipe connecting the rolling oil pipe and the cavity is provided at the end of the spray beam, and a plurality of nozzles connected to the cavity are distributed on the side of the spray beam facing the support roll, and the rolling oil enters the cavity through the oil inlet pipe and is then sprayed onto the roll surface of the support roll by the nozzle.

[0006] Furthermore, the nozzle has an oil inlet and an oil outlet which are interconnected. The oil inlet is connected to the cavity of the injection beam, and the oil outlet faces the roller surface of the support roller. The rolling oil enters the cavity through the oil inlet pipe on the injection beam, and then enters the oil inlet of the nozzle, and then passes through the pressurizing mechanism inside the nozzle and is sprayed out from the oil outlet onto the roller surface of the support roller.

[0007] Furthermore, the pressurizing mechanism inside the nozzle is a small pump or a pressure regulating valve.

[0008] Furthermore, the support frame is provided with two upper and lower platforms, and a spray beam is fixed on each platform, wherein the spray beam on the upper platform cools and cleans the upper support roller, and the spray beam on the lower platform cools and cleans the lower support roller.

[0009] Furthermore, universal wheels are provided at the bottom of the support frame.

[0010] Furthermore, the nozzles on the spray beam are distributed in an array, with three rows.

[0011] Furthermore, among the nozzles distributed in the array, the nozzles near the two ends of the spray beam are closely arranged, and the nozzles near the middle of the spray beam are arranged at intervals.

[0012] After adopting the above scheme, the beneficial effects of the utility model are:

[0013] Automation and high efficiency: The utility model specially designs a spray beam, which replaces manual flushing, and can more effectively cool and clean the support rollers during grinding. The operator does not need to hold the rolling oil pipe in real time to cool and flush the support rollers. This not only greatly improves the work efficiency, solves the problem of low efficiency of manual cooling and cleaning with a rolling oil spray gun, but also reduces the labor intensity and fatigue of the operator.

[0014] Uniform cooling and cleaning: The nozzle design distributed on the spray beam allows the rolling oil to be evenly sprayed on the roller surface of the support roller. This not only ensures the comprehensive cooling of the support roller, but also effectively removes aluminum chips and other impurities, improving the cleanliness of the support roller.

[0015] The utility model also has universal wheels at the bottom of the support frame. This design allows the operator to easily move the device to the desired position by simply pushing or pulling without the need for additional equipment. It can easily meet the cooling and cleaning needs of the support rollers of the rolling mill at different positions, further improving work efficiency and adaptability.

[0027] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] The utility model provides a new cooling and cleaning device for roller grinding, such as Figures 1 to 8 As shown, it includes a support frame 1, and at least two spray beams 2 are arranged on the support frame 1, corresponding to the upper support roller 6 and the lower support roller 6 respectively. The support frame 1 serves as the basis of the entire device, firmly supporting the spray beam 2, and the design of the spray beam 2 can extend along the length direction of the support roller 6, ensuring that the entire support roller 6 can be effectively cooled and cleaned during the grinding process. The spray beam 2 has a cavity 21, and this cavity 21 is connected to the external rolling oil pipe through an oil inlet pipe 22, so as to ensure that the rolling oil can flow in smoothly. A plurality of nozzles 3 connected to the cavity 21 are distributed on the side of the spray beam 2 facing the support roller 6, and the nozzle 3 is fixed on the spray beam 2 by bolts 4 and a mounting plate 5. When the rolling oil enters the cavity 21 from the oil inlet pipe 22, it will be evenly sprayed from the nozzle 3 to the roller surface of the support roller 6. The design of the entire device enables the automatic cooling and cleaning of the support roller 6 to be achieved without manual intervention when the support roller 6 is ground.

[0029] Key References Figures 4 to 6The nozzle 3 has an oil inlet 31 and an oil outlet 32 ​​which are connected to each other. The oil inlet 31 is connected to the cavity 21 of the spray beam 2, and the oil outlet 32 ​​faces the roller surface of the support roller 6. The purpose of this design is to spray the rolling oil directly and accurately to the part of the support roller 6 that needs to be cooled and cleaned. The rolling oil enters the cavity 21 through the oil inlet pipe 22 on the spray beam 2, and then enters the oil inlet 31 of the nozzle 3. A pressurizing mechanism 33, such as a small pump or a pressure regulating valve, may be provided inside the nozzle 3 to pressurize the rolling oil. The pressurized rolling oil is sprayed out through the oil outlet 32 ​​at a higher speed and a smaller spray angle, so that it can be sprayed on the roller surface of the support roller 6 more effectively. The pressurized sprayed rolling oil can better penetrate into the tiny gaps and grooves on the surface of the support roller 6, so as to more effectively remove aluminum chips and other impurities, and quickly reduce the temperature of the roller surface. In addition, the nozzle 3 has strong adaptability, and the design of the nozzle 3 can be adjusted according to the specific shape and size of the support roller 6 to adapt to support rollers 6 of different specifications and types.

[0030] In practical applications, the support rollers 6 of a rolling mill are usually composed of two rollers, an upper support roller 6 and a lower support roller 6. Both rollers may generate aluminum chips and accumulate heat during the rolling process, so they need to be cooled and cleaned. In order to improve the cleaning efficiency and ensure that both support rollers 6 can be processed in time, the present embodiment optimizes the cooling and cleaning device. Specifically, Figure 1 to Figure 2 As shown, two platforms 11 distributed up and down are provided on the support frame 1. The design of the two platforms 11 ensures a stable operating space, so that the spray beam 2 can be fixed thereon, and is easy to adjust and maintain. A spray beam 2 is fixed on each platform 11, so that the spray beam 2 on the upper platform 11 can focus on cooling and cleaning the upper support roller 6, while the spray beam 2 on the lower platform 11 is specifically responsible for performing the same operation on the lower support roller 6. Through this design, the device can cool and clean the upper and lower support rollers 6 at the same time when the support roller 6 is polished, which significantly improves the work efficiency. In addition, since the two spray beams 2 are operated independently, the spray angle, flow rate and pressure of each spray beam 2 can be adjusted separately according to actual conditions to meet the cooling and cleaning requirements of different support rollers 6. This design not only improves the efficiency of cooling and cleaning, but also enhances the adaptability and flexibility of the device, so that it can better adapt to different production environments and needs.

[0031] The nozzles 3 on the beam are distributed in an array, and the number of rows and columns of the nozzles 3 can be determined according to actual application requirements. Figure 2 The single-line setting shown can also be Figure 1As shown, the nozzles 3 on the spray beam 2 are arranged in a three-row array. This layout ensures that the rolling oil can evenly and comprehensively cover the entire roller surface of the support roller 6, thereby improving the cooling and cleaning effects. Each row of nozzles 3 is closely arranged to minimize the spray blind area and ensure that the rolling oil can be sprayed to every part of the support roller 6. The nozzles 3 near the two ends of the spray beam 2 are designed to be closely arranged, while the nozzles 3 in the middle are arranged at intervals. This design takes into account the characteristics of the roller surface of the support roller 6, that is, the two ends usually require more intensive cooling and cleaning to ensure that the aluminum chips and heat in the edge area are effectively treated. Therefore, the close arrangement of the nozzles 3 at both ends can provide a higher spray density to ensure that the edge area is fully cleaned. In contrast, the middle area is closer to the rolling center, so too much aluminum chips are usually not accumulated, and the temperature distribution is relatively uniform. Therefore, the nozzles 3 in the middle are arranged at intervals, which can reduce unnecessary rolling oil consumption and ensure that the middle area is properly cooled and cleaned.

[0032] When the support rollers 6 of different rolling mills need to be cooled and cleaned, the mobility of the cooling and cleaning device becomes particularly important. In order to ensure that the device can be quickly and conveniently transferred to the rolling mill that needs to be cleaned, it is usually transferred using external equipment such as a trailer. This transfer method also requires additional equipment and is very inconvenient. In this embodiment, a universal wheel 12 is provided at the bottom of the support frame 1, such as Figures 1 to 2 As shown, this design allows the operator to easily move the device to the desired position by simply pushing or pulling without the need for additional equipment, and can easily cope with the cooling and cleaning needs of the support rolls 6 of the rolling mill at different positions, greatly improving work efficiency and adaptability.

[0033] The working process of the new cooling and cleaning device for roller grinding is as follows:

[0034] Key References Figure 8 When the support roller 6 is to be polished, it is necessary to pull it out of the mill arch, install the polishing device on one side of it, and drive the support roller 6 to rotate for polishing through the hydraulic motor on the polishing device. When the support roller 6 needs to be cooled and cleaned, first pull the cooling and cleaning device to the specified position, and then connect the rolling oil pipe of the rolling mill with the oil inlet pipe 22 of the spray beam 2. The rolling oil enters the cavity 21 of the spray beam 2 through the oil inlet pipe 22, and then enters the oil inlet 31 of the nozzle 3. Then, the rolling oil is pressurized inside the nozzle 3, and the rolling oil is sprayed from the oil outlet 32 ​​onto the roller surface of the upper and lower support rollers 6 to cool and clean the support roller 6 being polished. After cleaning, the support frame 1 and the spray beam 2 thereon can be removed through the universal wheel 12, or moved to another rolling mill that needs to be cleaned.
