Description

Technical Field

[0001] The present invention relates to the technical field of sol coating, and specifically to a cooling roll mechanism for double-end isothermal sol coating. Background Art

[0002] The sol coating process is a process technology for uniformly coating a sol material on the surface of a substrate. Based on the sol-to-gel conversion process, a coating on the surface of the substrate is prepared to achieve the purpose of surface modification of the substrate. Due to its unique material properties and processing advantages, the sol coating process is widely used in different fields; The cooling roll plays a crucial role in the sol coating process and is a core component for ensuring coating quality and improving coating efficiency. Through precise temperature management and physical structure design, the cooling roll uses water cooling or oil cooling methods to remove heat and reduce temperature, significantly reducing the shrinkage rate of the material after sol coating and preventing wrinkles caused by thermal stress.

[0003] After searching for the invention patent with the authorized announcement number CN105437433B, a dew-free cooling roll is disclosed. The cooling roll includes: a roll body, which includes: a roll wall that forms a cylindrical shape with a hollow cavity; a cooling device connected to the roll body for the circulation of a coolant; and a heat conduction layer provided in the roll wall or on the outer periphery of the roll wall to transfer heat to both ends of the roll wall.

[0004] Based on the above patent, combined with existing solutions and the actual use process, there are still some problems with the current cooling roll mechanism. For example: In the first solution of the above patent, the cooling device is two single-loop rotary joints, which are respectively connected to both ends of the roll body. The coolant enters the cavity of the roll body through one single-loop rotary joint and is discharged from the other single-loop rotary joint. In the second solution of the above patent, the cooling device is a double-loop rotary joint, which is connected to one end of the roll body. The coolant enters the cavity of the roll body through one port of the double-loop rotary joint and is discharged from the other port of the double-loop rotary joint. In the third solution of the above patent, the cooling device is a cooling pipe accommodated in the cavity of the roll body, and the coolant enters from one end of the cooling pipe and is discharged from the other end of the cooling pipe; In summary, for the three solutions in the above patent, the same as the existing cooling roll, in the existing cooling roll, the coolant flows in from one end of the roll body and flows out from the other end of the roll body, and all perform cooling treatment with the coolant flowing unidirectionally in a single flow path inside the cooling roll. However, when the coolant flows unidirectionally from one end to the other end of the roll body, it will cause the temperature of the coolant itself to gradually increase, resulting in a significant difference in temperature between the coolant inlet end and the coolant outlet end of the roll body, and making the temperature of the roll body uneven, reducing the heat dissipation efficiency of the coolant outlet end of the roll body. At the same time, the uneven temperature will also cause the problem of dew condensation on the roll body.

[0005] Therefore, we propose a cooling roller mechanism for double-end isothermal sol coating to facilitate the solution of the problems mentioned above. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: For this double-end isothermal sol coating cooling roller mechanism, the two-way flow channel is used for the two-way transportation of the coolant, so that the overall temperature of the roller body is evenly arranged, ensuring that the temperatures at both ends of the cooling roller mechanism are set in an isothermal state. In addition, through the convenient detachable structure, it is easy to carry out the convenient disassembly and cleaning of each component, avoiding the influence of scale blockage on the flow of the coolant; 1. The first spiral channel and the second spiral channel are arranged in a staggered state on the inner shell of the roller, located at the gap between the outer shell of the roller and the inner shell of the roller. The first spiral channel and the second spiral channel are sealed and separated by a spiral sealing strip, so that the first spiral channel forms a one-way flow channel from left to right, for the coolant to be conveyed directionally from left to right in a spiral manner on the inner shell of the roller, and the second spiral channel forms a one-way flow channel from right to left, for the coolant to be conveyed directionally from right to left in a spiral manner on the inner shell of the roller. Through the cooperation of the first spiral channel and the second spiral channel, the temperature of the coolant in the two is complementary, and the two-way flow channel is used for the two-way conveyance of the coolant, which is different from the one-way flow of the coolant in the existing cooling roller, avoiding temperature differences at the inlet end and the outlet end of the roller body, and making the overall temperature on the outer shell of the roller evenly arranged, ensuring that the temperatures at both ends of the cooling roller mechanism are set at the same temperature, and avoiding condensation on the outer shell of the roller; Further, the sealing methods at the connection between the main liquid inlet channel and the liquid inlet ring groove, the connection between the main liquid outlet channel and the liquid outlet ring groove, the connection between the auxiliary liquid inlet channel and the liquid inlet ring groove, and the connection between the auxiliary liquid outlet channel and the liquid outlet ring groove are the same. A primary seal is carried out through an "O" - ring, and a secondary seal is carried out through a sealing component. Through the double - seal setting, the leakage - proof supply of the coolant is ensured, avoiding the difference in the overall temperature on the outer shell of the roller caused by the leakage of the coolant, and further affecting the cooling effect of the sol coating material; Further, regarding the sealing method at the connection between the main liquid inlet channel and the liquid inlet ring groove, the elastic deformation of the first spring is used to push the moving ring part to slide, so that the moving ring part drives the pressure - resistant sealing ring to press - seal at the connection between the pipe shell frame and the main end seat, and the tapered ring end at the inner circle of the pressure - resistant sealing ring is inserted into the hydraulic ring cavity. The coolant leaking from the sealing part of the "O" - ring fills the hydraulic ring cavity, and after forming pressure, it pushes the tapered ring end at the inner circle of the pressure - resistant sealing ring, so that the inner - circle wall of the pressure - resistant sealing ring is tightly sealed against the main end seat, ensuring the sealing reliability at the rotating connection between the pipe shell frame and the main end seat; 2. Loosen the threaded connection between the fixing cap and the bolt rod, release the assembly fixation between the main end seat and the sub - end seat, disassemble the main end seat and the sub - end seat on the outer shell of the roller respectively, and release the clamping fixation of the main end seat and the sub - end seat on the inner shell of the roller, and then disassemble the inner shell of the roller on the outer shell of the roller. Through the convenient disassembly structure setting, it is easy to carry out the convenient disassembly and cleaning of each component, avoiding the influence of scale blockage on the flow of the coolant; Further, after the main end shaft seat is assembled, the inward limiting ring therein is clamped and pressed against the left barrel opening of the roller shell, and is sealed by a sealing ring gasket. And the inward end thereof is inserted and pressed against the left barrel opening of the roller inner shell, and is sealed by a pressing and sealing mechanism. When the pressing and sealing mechanism seals, the square plug column in the main end shaft seat pushes and extrudes the inward frame body in the linkage frame. After the linkage frame flips, the outer frame body therein toggles the moving pipe seat, so that the moving pipe seat drives the sealing ring sleeve to be pressed against the connection between the roller inner shell and the main end shaft seat. The sealing method after the auxiliary end shaft seat is assembled is the same as that after the main end shaft seat is assembled, and synchronous sealing treatment is realized during assembly, ensuring the operation convenience.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0020] Embodiment 1: The present invention provides a technical solution: A cooling roller mechanism for double - end isothermal sol coating. In response to the problem that in the existing cooling roller, the coolant flows unidirectionally from one end of the roller body to the other end, and through the unidirectional cooling method of the single - flow channel of the coolant, it is easy to cause a temperature difference between the coolant inlet end of the roller body and the coolant outlet end of the roller body, resulting in uneven temperature of the roller body, and then easily causing condensation on the roller body, affecting the cooling effect of the sol coating material. The first spiral channel 4 and the second spiral channel 5 are arranged in a staggered state on the inner roller shell 2. The first spiral channel 4 is used for the coolant to be directionally transported in a spiral manner from left to right on the inner roller shell 2, and the second spiral channel 5 is used for the coolant to be directionally transported in a spiral manner from right to left on the inner roller shell 2. Through the cooperation of the first spiral channel 4 and the second spiral channel 5 for the two - way flow channel transportation of the coolant, the coolant in the first spiral channel 4 and the coolant in the second spiral channel 5 are temperature - complementary, so that the overall temperature on the barrel of the roller shell 1 is evenly arranged.

[0021] This technical solution: Please refer to Figures 1 - 9 , A cooling roller mechanism for double - end isothermal sol coating, including a roller shell 1. The left and right side openings of the roller shell 1 are both set in an open state. The inner roller shell 2 is hermetically inserted into the barrel cavity of the roller shell 1. The left and right side openings of the inner roller shell 2 are both set in an open state; It also includes a main end shaft seat 3 and a secondary end shaft seat 6. The main end shaft seat 3 is hermetically arranged at the left side opening of the inner shell 2 of the roller, and the main end shaft seat 3 is used for the inflow of the coolant into the first spiral channel 4 and for the outflow of the coolant out of the second spiral channel 5. The first spiral channel 4 is used for the directional conveyance of the coolant on the inner shell 2 of the roller from left to right, and the second spiral channel 5 is used for the directional conveyance of the coolant on the inner shell 2 of the roller from right to left. Through the two-way flow channel conveyance of the coolant, the overall temperature on the outer shell 1 of the roller is evenly complemented. The secondary end shaft seat 6 is hermetically arranged at the right side opening of the inner shell 2 of the roller, and the secondary end shaft seat 6 is used for the outflow of the coolant out of the first spiral channel 4 and for the inflow of the coolant into the second spiral channel 5. Liquid supply mechanisms 7 for preventing leakage of the coolant are arranged outside both the secondary end shaft seat 6 and the main end shaft seat 3.

[0022] Specifically, in this technical solution, the directional conveyance operation of the coolant on the inner shell 2 of the roller from left to right is carried out through the first spiral channel 4. According to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 shown, a liquid supply mechanism 7 for preventing leakage of the coolant is arranged outside the main end shaft seat 3. The liquid supply mechanism 7 includes a pipe shell frame 9, an inlet liquid ring groove 10 and an outlet liquid ring groove 11. One section of the pipe shell frame 9 facing away from the outer shell 1 of the roller is the outward section, and the inlet liquid ring groove 10 is opened on the wall of the outer cavity of the outward section of the pipe shell frame 9. One section of the pipe shell frame 9 facing the outer shell 1 of the roller is the inward section, and the outlet liquid ring groove 11 is opened on the wall of the inner cavity of the inward section of the pipe shell frame 9. Since a connecting pipe part communicated with it is arranged on the lower side of the inlet liquid ring groove 10, wherein the connecting pipe part is integrally arranged on the outer pipe body of the outward section of the pipe shell frame 9, and since a connecting pipe part communicated with it is arranged on the lower side of the outlet liquid ring groove 11, wherein the connecting pipe part is integrally arranged on the inner pipe body of the inward section of the pipe shell frame 9. The connecting pipe part in the inlet liquid ring groove 10 is externally connected to the liquid supply pipeline in the coolant preparation device, and the connecting pipe part in the outlet liquid ring groove 11 is externally connected to the liquid return pipeline in the coolant preparation device (the above-mentioned coolant preparation device is a prior art and is not described in the attached drawings of the specification); Since the main liquid inlet channel 301 is opened at the lower part of the main end shaft seat 3, and fluid ports in an open state are provided at both ends thereof, the fluid port at one end of the main liquid inlet channel 301 facing the inner shell 2 of the roller is an inward fluid port, and the fluid port at the other end of the main liquid inlet channel 301 away from the inner shell 2 of the roller is an outward fluid port. The liquid inlet ring groove 10 is correspondingly communicated with the outward fluid port in the main liquid inlet channel 301. Also, since the two "O" - rings 12 at the outward fluid port in the main liquid inlet channel 301 are symmetrically arranged about the center of the outward fluid port in the main liquid inlet channel 301 and are respectively placed on both sides of the outward fluid port in the main liquid inlet channel 301. Moreover, since the two sealing assemblies 13 at the liquid inlet ring groove 10 are symmetrically arranged about the center of the liquid inlet ring groove 10 and are relatively oriented and respectively placed on both sides of the liquid inlet ring groove 10. The two "O" - rings 12 at the outward fluid port in the main liquid inlet channel 301 are respectively used for the primary sealing treatment on both sides of the connection between the liquid inlet ring groove 10 and the main liquid inlet channel 301, and the two sealing assemblies 13 at the liquid inlet ring groove 10 are respectively used for the secondary sealing treatment on both sides of the connection between the liquid inlet ring groove 10 and the main liquid inlet channel 301. After the sealing treatment of the connection between the liquid inlet ring groove 10 and the main liquid inlet channel 301 is completed, the main end shaft seat 3 is used for the inlet of the coolant into the first spiral channel 4. The coolant is transported into the liquid inlet ring groove 10 through the liquid supply pipeline in the coolant preparation device. After the coolant fills the liquid inlet ring groove 10, it is transported into the main liquid inlet channel 301 through the outward fluid port in the main liquid inlet channel 301; Since the inner shell 2 of the roller is sealingly inserted into the barrel cavity of the outer shell 1 of the roller, the left - hand barrel opening of the inner shell 2 of the roller is flush with the left - hand barrel opening of the outer shell 1 of the roller. Also, since the main end shaft seat 3 is sealingly arranged at the left - hand barrel opening of the inner shell 2 of the roller, and the main end shaft seat 3 is simultaneously sealingly arranged at the connection between the left - hand barrel opening in the inner shell 2 of the roller and the left - hand barrel opening in the outer shell 1 of the roller. Moreover, since both ends of the first spiral channel 4 are in a closed state, and a first liquid inlet 401 communicated therewith is opened at its left end. The first liquid inlet 401 is located on the lower side wall at the left end of the inner shell 2 of the roller and is correspondingly communicated with the inward fluid port in the main liquid inlet channel 301. After the first liquid inlet 401 and the inward fluid port in the main liquid inlet channel 301 are sealingly communicated, the coolant in the main liquid inlet channel 301 is transported into the first spiral channel 4 through the first liquid inlet 401; Since the first spiral channel 4 is a one - way flow channel and is recessedly opened on the inner shell 2 of the roller, after the coolant enters the first spiral channel 4, it flows along the first spiral channel 4, so that the coolant is directionally transported in a spiral manner from left to right on the inner shell 2 of the roller; Since the inner shell 2 of the roller is hermetically inserted into the barrel cavity of the outer shell 1 of the roller, the right barrel opening of the inner shell 2 of the roller is flush with the right barrel opening of the outer shell 1 of the roller. The auxiliary end shaft seat 6 is hermetically arranged at the right barrel opening of the inner shell 2 of the roller, and the auxiliary end shaft seat 6 is also hermetically arranged at the connection between the right barrel opening in the inner shell 2 of the roller and the right barrel opening in the outer shell 1 of the roller. Also, since the auxiliary liquid outlet channel 602 is opened at the upper part of the auxiliary end shaft seat 6, and flow ports in an open state are arranged at both ends thereof. The flow port of the auxiliary liquid outlet channel 602 facing the inner shell 2 of the roller is the inward flow port, and the flow port of the auxiliary liquid outlet channel 602 facing away from the inner shell 2 of the roller is the outward flow port. Further, since the right end of the first spiral channel 4 is provided with a first liquid outlet 402 communicating therewith, the first liquid outlet 402 is placed on the upper side wall at the right end of the inner shell 2 of the roller, and it is correspondingly and communicatively arranged with the inward flow port in the auxiliary liquid outlet channel 602. After the first liquid outlet 402 and the inward flow port in the auxiliary liquid outlet channel 602 are hermetically communicated, the coolant flowing in the first spiral channel 4 flows out of the first spiral channel 4 through the first liquid outlet 402 and flows into the auxiliary liquid outlet channel 602 through the inward flow port in the auxiliary liquid outlet channel 602; Since a liquid supply mechanism 7 for preventing leakage of the coolant is also arranged outside the auxiliary end shaft seat 6, the arrangement manner between the auxiliary end shaft seat 6 and the liquid supply mechanism 7 is the same as the arrangement manner between the main end shaft seat 3 and the liquid supply mechanism 7, and the sealing manner between the auxiliary end shaft seat 6 and the liquid supply mechanism 7 is the same as the sealing manner between the main end shaft seat 3 and the liquid supply mechanism 7. Also, since the two "O" - rings 12 at the outward flow port in the auxiliary liquid outlet channel 602 are symmetrically arranged about the center of the outward flow port in the auxiliary liquid outlet channel 602 and are respectively placed on both sides of the outward flow port in the auxiliary liquid outlet channel 602. Further, since the two sealing components 13 at the liquid outlet ring groove 11 are symmetrically arranged about the center of the liquid outlet ring groove 11 and are oppositely oriented and respectively placed on both sides of the liquid outlet ring groove 11. The two "O" - rings 12 at the outward flow port in the auxiliary liquid outlet channel 602 are respectively used for the primary sealing treatment on both sides of the connection between the liquid outlet ring groove 11 and the auxiliary liquid outlet channel 602, and the two sealing components 13 at the liquid outlet ring groove 11 are respectively used for the secondary sealing treatment on both sides of the connection between the liquid outlet ring groove 11 and the auxiliary liquid outlet channel 602. After the sealing treatment of the connection between the liquid outlet ring groove 11 and the auxiliary liquid outlet channel 602 is completed, the auxiliary end shaft seat 6 is used for the liquid outlet of the coolant to the outside of the first spiral channel 4. The liquid outlet ring groove 11 is correspondingly and communicatively arranged with the outward flow port in the auxiliary liquid outlet channel 602. The coolant in the auxiliary liquid outlet channel 602 flows into the liquid outlet ring groove 11 through the outward flow port in the auxiliary liquid outlet channel 602, and the coolant fills the liquid outlet ring groove 11. The coolant in the liquid outlet ring groove 11 flows into the return pipeline in the coolant preparation device, realizing the left - to - right circular flow of the coolant in the first spiral channel 4.

[0023] Specifically, in this technical solution, the coolant is directionally transported from right to left on the inner shell 2 of the roller through the second spiral channel 5, according to Figure 1 、Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, according to the above, the method of directional coolant delivery through the first spiral channel 4 is that the main end shaft seat 3 delivers the coolant into the first spiral channel 4, and after the coolant passes through the first spiral channel 4, the secondary end shaft seat 6 delivers the coolant out of the first spiral channel 4. The delivery method used in the first spiral channel 4 is the same as the delivery method used in the second spiral channel 5. The difference is that the delivery directions of the first spiral channel 4 and the second spiral channel 5 are opposite. The method of directional coolant delivery through the second spiral channel 5 is that the secondary end shaft seat 6 delivers the coolant into the second spiral channel 5, and after the coolant passes through the second spiral channel 5, the main end shaft seat 3 delivers the coolant out of the second spiral channel 5. Since the secondary liquid inlet channel 601 is provided at the lower part of the secondary end shaft seat 6, both ends thereof are provided with open flow channel openings, the flow channel opening in the secondary liquid inlet channel 601 facing one end of the roller inner shell 2 is the inward flow channel opening, and the flow channel opening in the secondary liquid inlet channel 601 facing away from one end of the roller inner shell 2 is the outward flow channel opening, and the liquid inlet annular groove 10 is connected to the outward flow channel opening in the secondary liquid inlet channel 601 in a corresponding manner, and because the two "O" rings 12 at the outward flow channel opening in the secondary liquid inlet channel 601 are respectively used for the liquid inlet annular groove 10 and the two sides of the connection between the secondary liquid inlet channel 601 A primary sealing treatment is performed, and two sealing components 13 at the liquid inlet annular groove 10 are used for secondary sealing treatment on both sides of the connection between the liquid inlet annular groove 10 and the secondary liquid inlet channel 601.

The opening method of the hydraulic ring cavity 14 at the liquid - outlet ring groove 11 is the same as the opening method of the hydraulic ring cavity 14 at the liquid - inlet ring groove 10. Also, since the side of the "O" - ring 12 facing away from the liquid - inlet ring groove 10 is the outer side, the two sealing assemblies 13 are respectively placed on the outer sides of the two "O" - rings 12.

Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a spiral sealing strip 8 is arranged between the first spiral track 4 and the second spiral track 5. Since the spiral sealing strip 8 is fixedly clamped on the roller inner shell 2 after being installed, and the spiral sealing strip 8 is sealed and fitted with the cylinder cavity wall of the roller outer shell 1, the spiral sealing strip 8 is used to separate the first spiral track 4 and the second spiral track 5, so that the first spiral track 4 and the second spiral track 5 form independent flow channels respectively, and assist the two-way flow channel transportation of the coolant; Since the specifications and dimensions of the first spiral track 4 are the same as those of the second spiral track 5, and the spiral centers of the two are on the same horizontal central axis as the cylinder center of the roller inner shell 2, and the spiral directions of the two are set in the same way, and since the first spiral track 4 and the second spiral track 5 are arranged in a staggered state, the first spiral track 4 is used for the directional transportation of the cooling liquid from left to right in a spiral manner, and the second spiral track 5 is used for the directional transportation of the cooling liquid from right to left in a spiral manner, the cooling liquid in the first spiral track 4 and the cooling liquid in the second spiral track 5 are staggered to make the temperature of the two be uniform and complementary, so as to achieve the overall uniform temperature arrangement on the cylinder body of the roller outer shell 1, and ensure that both ends of the roller outer shell 1 are set in a state of isotherm; Since the end of the main end shaft seat 3 facing the roller shell 1 is the inward end, and the end thereof facing away from the roller shell 1 is the outward end, the main end shaft seat 3 is arranged in a parallel state on the left side of the roller shell 1 after being installed, and the two are on the same horizontal central axis, and an integrated shaft column portion is arranged at the central position of the outward end of the main end shaft seat 3, wherein the horizontal central axis of the shaft column portion coincides with the horizontal central axis of the main end shaft seat 3.
