DETAILED DESCRIPTION

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] like Figure 1 - Figure 9 As shown, a glass rolling apparatus includes a support plate 1 and a heat exchange pump group 32. Side plates 1 and 2 and 3 are arranged symmetrically on the upper side of the support plate 1. Two rolling rollers 4 are arranged between side plates 1 and 2 and side plates 3. A cold flow channel 5 is arranged on the inner side of the rolling roller 4. The cold flow channel 5 has a spiral variable diameter flow channel structure. A metal-ceramic composite is sleeved on the outer side of the rolling roller 4. A cold flow injection hole 6 is arranged on one side of the rolling roller 4, and several drainage holes 7 are arranged on the other side. A drive assembly is arranged on side plate 1, a cold flow conveying section is arranged on side plate 2, and a heat flow conveying conversion section is arranged on side plate 4.

[0035] Among them, the spiral variable diameter flow channel structure refers to a channel structure in which the cross-sectional dimensions of the flow channel change regularly along the spiral axis, for example, by using a pipe diameter design that alternates between gradually narrowing and gradually expanding. This structure can break the laminar boundary layer, enhance the turbulence intensity of the coolant, and allow the fluid to fully contact the inner wall of the roller.

[0036] Metal-ceramic composites consist of a metal substrate and a ceramic coating. For example, tungsten carbide hard alloy can be used as the surface material. The composite structure is formed by thermal spraying, which improves the surface thermal conductivity while maintaining the mechanical strength of the roller.

[0037] The cold flow injection hole and the drain hole form a pressure difference drive system. For example, the drain hole can be set with a diameter of 0.5-3mm and distributed in a honeycomb array to ensure that the coolant is discharged evenly after flowing through the spiral channel.

[0038] The drive components and the cold flow delivery parts are arranged separately, for example, the motor drive system and the coolant circulation system are arranged on the two side plates respectively, to avoid vibration interfering with the stability of fluid delivery.

[0039] Specifically, when the coolant enters the spiral variable diameter flow channel through the cold flow injection hole 6, the Venturi effect generated by the variable diameter structure accelerates the fluid movement, while the periodic pipe diameter change induces the formation of vortices.

[0040] The high thermal conductivity of the metal-ceramic composite component allows heat from the roller surface to be quickly transferred to the flow channel wall. The spiral path extends the contact time between the coolant and the flow channel wall. After the coolant completes the heat exchange, it is discharged through the drain hole 7 and the waste heat is recovered through the heat flow transfer conversion unit, forming a closed-loop energy cycle.

[0041] The symmetrical arrangement of the two calendering rolls 4 forms a stable calendering working area, and the independent setting of the drive components avoids mutual interference between the cooling system and the power system.

[0042] Compared with the prior art, the cooling liquid in the conventional straight-through flow channel flows in a laminar state in one direction, resulting in a significant temperature gradient in the axial direction of the roller body. The spiral variable-diameter flow channel of the present application forces the fluid to change direction and flow rate, causing strong turbulence in the radial and axial directions of the cooling liquid. For example, the turbulence intensity can be increased by more than 40% under the same flow rate.

[0043] The thermal conductivity of the cermet composite structure is increased by about 30% compared with that of the conventional alloy roller body, and the surface hardness is increased by 2-3 times. The closed-loop cooling circulation system reduces the cooling liquid loss by about 25% compared with the conventional open system.

[0044] The driving assembly includes a mounting bracket 8 arranged on one side of the side plate 1, a motor 9 arranged on one side of the mounting bracket 8, a gear 1 0 arranged on the output shaft end of the motor 9, a gear 2 1 engaged with one side of the gear 1 0, and a gear 3 1 engaged with one side of the gear 2 1.

[0045] The mounting bracket 8 is a support structure for fixing the motor and can be realized by steel plate welding or casting integral molding to provide rigid support for the motor 9 and avoid gear meshing deviation caused by vibration during transmission.

[0046] The gear 1 0 and the gear 2 1 are engaged, which means that the power is transmitted through the tooth surface contact, for example, using helical gears or spur gears to form a one-stage speed reduction transmission, which reduces the speed while improving the torque output stability, thereby reducing the speed fluctuation of the calender roller.

[0047] The gear 2 1 is sleeved on one side of the calender roller 4, which means that the power is transmitted through key groove cooperation or interference assembly, for example, using flange connection or spline connection to directly convert the rotary motion of the gear 2 1 into uniform rotation of the calender roller 4, avoiding energy loss or transmission delay caused by intermediate transmission links.

[0048] Specifically, the mounting bracket 8 is fixed on one side of the side plate 1, the motor 9 is installed on the mounting bracket 8, the gear 1 0 on the output shaft end is engaged with the gear 2 1 to form a one-stage speed reduction transmission structure, and the gear 2 1 is sleeved on the end of the calender roller through a rigid connection mode, so that the power output by the motor is directly transmitted to the calender roller 4 to ensure uniform rotation.

[0049] Due to the high contact precision of gear engagement transmission and the stable support of the mounting bracket 8, the vibration and speed fluctuation during transmission are effectively suppressed, and the uniform rotation of the calender roller 4 further ensures the stable flow of the cooling medium in the cold flow channel 5, thereby avoiding uneven distribution of the roller surface temperature caused by sudden speed change.

[0050] Compared with the prior art, the traditional driving assembly usually adopts chain or belt transmission, which is prone to transmission slip due to insufficient tension or wear, thereby causing the calender roller speed to fluctuate. The scheme combines gear meshing transmission with rigid mounting structure, eliminates the inherent defects of flexible transmission members, and significantly improves the reliability and stability of power transmission.

[0051] The cold flow conveying part comprises a cold flow placing assembly, a cold flow sucking assembly and a cold flow guiding assembly. The cold flow placing assembly comprises a cooling liquid tank arranged between the side plate one 2 and the side plate two 3. The upper side of the cooling liquid tank 13 is reversely connected with a tank cover 14.

[0052] The cold flow placing assembly refers to a modular structure for storing and supplying cooling liquid, which can be specifically implemented by a metal tank body fixedly arranged between the side plates, so that the position layout shortens the cooling liquid supply path and reduces the flow resistance.

[0053] The cooling liquid tank 13 refers to a container with a sealing cover, which can be specifically implemented by a stainless steel tank body formed by welding. The inside is provided with a partition plate to separate different functional areas, facilitating cooling liquid circulation and impurity precipitation.

[0054] The tank cover 14 is reversely connected, which means that the opening and closing operation is realized through a hinge structure. Specifically, a rotating shaft can be used in cooperation with a sealing rubber strip to facilitate the addition of cooling liquid while maintaining the closed state of the tank body to prevent external pollutants from entering.

[0055] The cold flow guiding assembly comprises a cold flow suction pipe 15 arranged in the cooling liquid tank 13. The cold flow suction pipe 15 is inserted with a cold flow guide pipe 16 at one side. One end of the cold flow guide pipe 16 is inserted with a cold flow shunt pipe 17. The end of the cold flow shunt pipe 17 is provided with a sealing bearing one 18 connected in the cold flow injection hole 6. The inside middle part of the cold flow shunt pipe 17 is provided with a shunt block 24.

[0056] The cold flow suction pipe 15 refers to a tubular structure for sucking cooling liquid from the cooling liquid tank. It can be made of metal or corrosion-resistant plastic material. The inlet end can extend to the bottom of the cooling liquid tank 13 to fully suck the liquid.

[0057] The cold flow guide pipe 16 refers to a connecting pipe for conveying cooling liquid. It can be specifically implemented by a detachable threaded interface or a buckle structure to facilitate quick disassembly and assembly during maintenance.

[0058] The cold flow shunt pipe 17 refers to a transition structure for uniformly distributing cooling liquid to the internal flow passage of the calender roller. The internal cavity cross section can be designed as a symmetrically tapered shape to adapt to the inlet requirements of the spiral-shaped variable-diameter flow passage.

[0059] The sealing bearing 18 refers to the rotating connecting component for realizing the dynamic sealing between the cold flow shunt pipe 17 and the calendering roller 4, which can adopt a mechanical seal or a magnetic fluid seal structure to ensure that the cooling liquid does not leak when the calendering roller rotates.

[0060] The shunt block 24 refers to a flow guiding structure arranged inside the cold flow shunt pipe, which can specifically adopt a tapered or airfoil profile to change the flow direction and balance the flow rate by guiding the fluid, so that the cooling liquid forms a stable laminar flow state before entering the calendering roller.

[0061] Specifically, after the cooling liquid is extracted from the cooling liquid tank 13 through the cold flow suction pipe 15, it is transported to the cold flow shunt pipe 17 through the cold flow guide pipe 16. The cold flow shunt pipe 17 is rotationally sealed and connected with the cold flow injection hole 6 of the calendering roller 4 through the sealing bearing 18, so that the cooling liquid can still be stably injected during the continuous rotation of the calendering roller 4,

[0062] The shunt block 24 guides the fluid in the middle of the cold flow shunt pipe 17, and the flow rate of the cooling liquid is balanced before entering the spiral-shaped variable-diameter flow channel inside the calendering roller 4 by changing the cross-sectional area of the flow channel. The cooperation structure of the sealing bearing 18 and the calendering roller 4 allows the cold flow shunt pipe to remain stationary while the calendering roller 4 rotates independently, avoiding pipe winding or sealing failure caused by relative motion. The plug-in structure of the cold flow guide pipe 16 and the cold flow suction pipe 15 facilitates quick separation during maintenance, and the shunt design of the cold flow shunt pipe 17 ensures that the cooling liquid is evenly distributed in the spiral flow channel, avoiding temperature fluctuations in local areas due to flow rate differences.

[0063] Compared with the prior art, when the traditional technology adopts a straight-through type cooling flow channel, the cooling liquid only flows along a fixed path, which is difficult to adapt to the rotating working condition of the calendering roller, and the uneven distribution caused by the lack of flow rate control. The present scheme realizes stable injection of the cooling liquid while maintaining rotational sealing through the cooperation of the cold flow shunt pipe 17 and the sealing bearing 18. The introduction of the shunt block 24 further optimizes the initial flow state of the fluid, so that the cooling liquid forms uniform coverage in the spiral-shaped variable-diameter flow channel, overcoming the low cooling efficiency problem caused by the single flow path in the traditional technology.

[0064] The cold flow suction assembly includes a connecting rod 12 arranged on one side of the gear 10. One end of the connecting rod 12 is provided with a gear 19. One side of the gear 19 is engaged with a gear 20. One side of the gear 20 is engaged with a gear 21. One side of the gear 21 is provided with a connecting rod 22. One end of the connecting rod 22 is provided with an impeller 23. The impeller 23 is arranged in the cold flow suction pipe 15.

[0065] The connecting rod 12 is a rod-shaped component for transmitting the rotating power of the gear 10. It can be connected to the shaft end of the gear by a steel shaft coupling to transmit the output power of the motor 9 to the cold flow suction assembly.

[0066] Among them, gear three 19, gear four 20 and gear five 21 refer to the meshing gear set forming a three-stage transmission relationship, which can be realized by adopting helical gears or spur gears to adjust the reduction ratio, and the rotation speed is reduced and the torque is increased through multi-stage meshing, so as to adapt to the working requirements of the impeller 23.

[0067] Among them, the impeller 23 refers to a centrifugal fluid driving part that generates negative pressure by rotating, which can be realized by adopting a stainless steel blade and shaft body integrated structure, which can suck and push the cooling liquid when placed inside the cold flow liquid suction pipe 15.

[0068] Specifically, the connecting rod one 12 obtains the rotating power output by the motor 9 through the gear one 10, drives the gear three 19 to rotate, the meshing of the gear three 19 and the gear four 20 completes the first-stage reduction, and the meshing of the gear four 20 and the gear five 21 realizes the second-stage reduction, and finally the adjusted rotation speed is transmitted to the impeller 23 through the connecting rod two 12. When the impeller 23 rotates in the cold flow liquid suction pipe 15, the negative pressure generated by the blade of the impeller 23 sucks the cooling liquid from the liquid suction pipe inlet and transports it to the cold flow injection hole 6 along the pipeline. Through the design of the reduction ratio of the three-stage gear transmission, the rotation speed of the impeller can be controlled within the range of the rotation speed of the calender roll, so as to avoid the sudden change of the cooling liquid flow caused by the too high rotation speed, and ensure the stability of the circulation process.

[0069] Compared with the prior art, the traditional cooling liquid circulation system needs to additionally configure an independent motor to drive the external pump body, which not only occupies space but also has high energy consumption. The present scheme directly utilizes the remaining power of the calender roll driving motor through the gear set, without the need to add an external power source. At the same time, the multi-stage reduction structure makes the rotation speed of the impeller and the rotation speed of the calender roll form a fixed proportional relationship, and the cooling liquid flow is automatically adjusted with the rotation speed of the calender roll, solving the flow matching problem caused by external independent driving.

[0070] The hot flow conveying and converting part includes a plug-in hole 27 arranged on one side of the side plate one 2, the calender roll 4 is plugged into the plug-in hole 27, one side of the plug-in hole 27 is provided with a liquid collecting groove 28, the liquid discharge hole 7 is arranged in a communicating state with the liquid collecting groove 28, two sealed bearings two 29 are arranged in the liquid collecting groove 28, the sealed bearings two 29 are connected with one end of the calender roll 4, an arc-shaped flow guide plate 30 is arranged in the liquid collecting groove 28, the arc-shaped flow guide plate 30 is located between the two sealed bearings two 29, a hot flow guide pipe 31 is arranged on one side of the liquid collecting groove 28, a heat pump group 32 is arranged outside the hot flow guide pipe 31, a partition plate 33 is arranged in the cooling liquid tank 13, an overflow hole 34 is arranged on the partition plate 33, a transfer groove 35 is arranged on one side of the partition plate 33, and one end of the hot flow guide pipe 31 is connected to one side of the transfer groove 35.

[0071] The plug-in hole 27 refers to the hole structure opened on the side of the side plate 1, which is used to accommodate the end of the calender roller 4 and form a rotating sealing connection. Specifically, a shaft sleeve and sealing ring combination structure can be used to achieve this, preventing the leakage of cooling liquid when the calender roller rotates.

[0072] The liquid collecting groove 28 refers to the groove structure provided on the side of the plug-in hole 27, which is in communication with the liquid discharge hole. Specifically, it can be formed by casting or welding, and is used to collect the heat flow discharged from the calender roller 4.

[0073] The sealing bearing 2 29 refers to a rolling bearing installed in the liquid collecting groove 28. Specifically, a double-row angular contact ball bearing can be used and filled with high-temperature resistant sealing grease to support the rotation of the calender roller while preventing the entry of heat flow into the bearing gap.

[0074] The arc-shaped flow guide plate 30 refers to a metal plate with a curved profile, which can be stamped from stainless steel plate to guide the heat flow along the preset path to the inlet of the heat flow conduit 31.

[0075] The partition plate 33 refers to a plate-shaped structure vertically arranged inside the cooling liquid tank 13, which can be cut from a polytetrafluoroethylene plate. The overflow hole 34 controls the layered height of the cold and hot fluids.

[0076] Specifically, the heat flow discharged from the calender roller 4 enters the liquid collecting groove 28 through the liquid discharge hole 7, and is directed by the arc-shaped flow guide plate 30 to flow towards the inlet of the heat flow conduit 31. The heat exchanger pump set 32 drives the heat flow to exchange heat through the heat flow conduit 31 and enter the transfer tank 35. Then, the cold flow enters the other side of the cooling liquid tank 13 through the overflow hole 34 under the blockage of the partition plate 33.

[0077] One side of the side plate 2 is provided with a receiving groove 25, and part of the cold flow conduit 16 is arranged in the receiving groove 25. A limiting block 26 is arranged in the receiving groove 25, and one side of the limiting block 26 abuts against one side of the cold flow conduit 16.

[0078] The receiving groove 25 refers to a groove structure formed on the surface of the side plate 2. It can be formed by milling or casting process, and its depth can be one-third to one-half of the thickness of the side plate 2, which is used to accommodate the partial structure of the cold flow conduit 16. The groove fixes the conduit inside the side plate 2 through physical limiting action.

[0079] The limiting block 26 refers to a rigid fixing piece embedded in the receiving groove 25. It can be a metal block or an engineering plastic block, and its height matches the depth of the receiving groove 25. It is fixed to the bottom of the receiving groove 25 by bolts or welding, and forms a surface contact with the side of the cold flow conduit 16. This structure limits the axial and radial displacement of the conduit through mechanical abutment.

[0080] Specifically, when the cold flow conduit is embedded in the receiving groove, the outer wall of the conduit and the inner wall of the receiving groove form a clearance fit, so that the axis of the conduit and the axis of the cold flow injection hole remain coaxial. When the cooling liquid flows through the conduit to generate pressure fluctuations or the equipment vibrates during operation, the limiting block counteracts the sliding tendency of the conduit along the length direction of the receiving groove by continuous contact with the side surface of the conduit. At the same time, the wrapping constraint of the side wall of the receiving groove on the conduit can inhibit the swing amplitude of the conduit in the direction perpendicular to the axis, avoiding the sealing failure of the connection between the cold flow injection hole and the sealed bearing one due to the displacement of the conduit.

[0081] Compared with the prior art, in the conventional cooling system, the conduit is usually directly exposed to the outside of the equipment and is simply fixed by relying on pipe clamps or straps, which cannot effectively inhibit the connection loosening caused by high-frequency vibration. However, the present scheme forms a double-rigid fixing mechanism by embedding the conduit inside the side plate two and setting the limiting block, so that the displacement of the conduit under mechanical vibration working condition is reduced by about 60%-80%, and the sealing reliability is significantly improved.

[0082] The side plate one 2 and the side plate two 3 on one side are provided with a protective shell 36, and the protective shell 36 on one side is reversely connected with a shell cover 37.

[0083] Among them, the protective shell 36 refers to the shell structure covering the outside of the side plate, which can be realized by metal stamping forming parts or injection molding parts. The inner cavity space completely wraps the connection area of the driving assembly and the cold and hot flow conveying part. This structure forms a physical isolation layer through closed design to block the intrusion path of external dust and debris.

[0084] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
