Description

Technical Field

[0001] The present invention relates to the technical field related to sol coating, in particular to a double-end isothermal cooling roller mechanism for sol coating. Background Art

[0002] Sol-gel coating is a process that uniformly coats a sol material onto a substrate surface. This process uses a sol-to-gel conversion process to achieve surface modification. Sol-gel coating is widely used in various fields due to its unique material properties and processing advantages.

[0003] The cooling roller plays a vital role in the sol-gel coating process and is a core component to ensure coating quality and improve coating efficiency. Through precise temperature management and physical structure design, the cooling roller uses water cooling or oil cooling to remove heat and cool down the material, significantly reducing the shrinkage rate of the material after sol-gel coating and preventing wrinkles caused by thermal stress.

[0004] After searching the invention patent with the authorization announcement number CN105437433B, a condensation-free cooling roller is disclosed. The cooling roller includes: a roller body, which includes: a roller wall, which is formed into a cylindrical shape with a hollow cavity; a cooling device, which is connected to the roller body and provides cooling liquid for circulation; a heat-conducting layer, which is arranged in the roller wall or on the outer periphery of the roller wall to transfer heat to both ends of the roller wall.

[0005] Based on the above patents and combined with existing solutions and actual use processes, the current cooling roller mechanism still has some problems, such as:

[0006] The first cooling device in the above patent is composed of two single-circuit rotary joints, which are respectively connected to the two ends of the roller body. The coolant enters the cavity of the roller body through one single-circuit rotary joint and is discharged from the other single-circuit rotary joint. The second cooling device in the above patent is composed of a double-circuit rotary joint, which is connected to one end of the roller body. The coolant enters the cavity of the roller body through one opening of the double-circuit rotary joint and is discharged from the other opening of the double-circuit rotary joint. The third cooling device in the above patent is a cooling pipe accommodated in the cavity of the roller body. The coolant enters from one end of the cooling pipe and is discharged from the other end of the cooling pipe.

[0007] In summary, the three schemes in the above patents are the same as the existing cooling rollers. In the existing cooling rollers, the coolant flows in from one end of the roller body and flows out from the other end of the roller body. The cooling treatment is performed by the unidirectional flow of the coolant in a single flow channel in the cooling roller. However, the unidirectional flow of the coolant from one end of the roller body to the other end will cause the coolant's own temperature to gradually increase, resulting in a significant difference in temperature between the roller body coolant inlet end and the roller body coolant outlet end, and making the roller body temperature uneven, reducing the heat dissipation efficiency of the roller body coolant outlet end. At the same time, the uneven temperature will also cause condensation problems on the roller body.

[0008] Therefore, we propose a double-end isothermal sol coating cooling roller mechanism to solve the above-mentioned problems. Summary of the Invention

[0009] The purpose of the present invention is to provide a double-end isothermal cooling roller mechanism for sol coating, so as to solve the problem proposed in the above-mentioned background technology that the cooling liquid flows in a single direction through a single channel, resulting in a significant temperature difference between the roller cooling liquid inlet end and the roller cooling liquid outlet end, resulting in uneven roller temperature, and then causing condensation on the roller, which affects the use.

[0030] Compared with the prior art, the present invention has the following beneficial effects: the double-end isothermal sol coating cooling roller mechanism utilizes a bidirectional flow channel to transport the coolant in both directions, so that the overall temperature of the roller body is uniformly arranged, thereby ensuring that the temperatures at both ends of the cooling roller mechanism are set at the same temperature. In addition, the convenient disassembly structure allows for easy disassembly and cleaning of the components, thereby preventing the blockage of the scale layer from affecting the flow of the coolant.

[0031] 1. The first spiral channel and the second spiral channel are arranged on the roller inner shell in an offset state and are placed in the gap between the roller outer shell and the roller inner shell. 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, which is used for the cooling liquid to be directed from left to right on the roller inner shell in a spiral manner, and the second spiral channel forms a one-way flow channel from right to left, which is used for the cooling liquid to be directed from right to left on the roller inner shell in a spiral manner. Through the cooperation of the first spiral channel and the second spiral channel, the temperatures of the cooling liquids in the two are complementary, and the cooling liquid is bidirectionally transported by using a bidirectional flow channel, which is different from the unidirectional flow of the cooling liquid in the existing cooling roller. The temperature difference between the roller inlet and the roller outlet is avoided, and the overall temperature of the roller shell is evenly distributed, which ensures that the temperatures at both ends of the cooling roller mechanism are set at the same temperature and avoids condensation on the roller shell.

[0032] Furthermore, the sealing method of the connection between the main liquid inlet channel and the liquid inlet annular groove, the sealing method of the connection between the main liquid outlet channel and the liquid outlet annular groove, the sealing method of the connection between the auxiliary liquid inlet channel and the liquid inlet annular groove, and the sealing method of the connection between the auxiliary liquid outlet channel and the liquid outlet annular groove are all arranged in the same manner, with a primary seal performed by an "O" ring and a secondary seal performed by a sealing assembly. The double sealing arrangement ensures the leak-proof supply of the coolant, avoids the difference in the overall temperature of the roller shell caused by coolant leakage, and thus avoids affecting the cooling effect of the sol coating material;

[0033] Furthermore, as for 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 pushes the dynamic ring to slide, so that the dynamic ring and the pressure sealing ring are pressed and sealed at the connection between the tube shell frame and the main end shaft seat, and the conical ring end at the inner ring of the pressure sealing ring is inserted into the hydraulic ring cavity. The coolant leaked from the sealing part of the "O" ring is filled into the hydraulic ring cavity. After the pressure is generated, the conical ring end at the inner ring of the pressure sealing ring is pushed, so that the inner ring wall of the pressure sealing ring is sealed and fitted on the main end shaft seat, thereby ensuring the sealing reliability of the rotating connection between the tube shell frame and the main end shaft seat.

[0034] 2. Loosen the threaded connection between the fixing cap and the bolt rod, release the assembly fixation between the main end shaft seat and the auxiliary end shaft seat, and remove the main end shaft seat and the auxiliary end shaft seat from the roller shell respectively. Release the clamping fixation of the main end shaft seat and the auxiliary end shaft seat on the roller inner shell, and remove the roller inner shell from the roller shell. The convenient disassembly structure makes it easy to disassemble and clean each component, avoiding the blockage of the scale layer affecting the flow of the coolant;

[0035] Furthermore, after the main end shaft seat is assembled, the inward limit ring is stuck and pressed against the left side of the roller shell, and is sealed by a sealing ring gasket, and the inward end is plugged and pressed against the left side of the roller inner shell, and is sealed by a pressure sealing mechanism. When the pressure sealing mechanism is sealed, the square plug in the main end shaft seat pushes the inward frame of the linkage frame, and after the linkage frame is flipped, the movable tube seat is moved through the outward frame, so that the movable tube seat drives the sealing ring sleeve to press against the connection between the roller inner shell and the main end shaft seat. The sealing method after the secondary end shaft seat is assembled is the same as that after the main end shaft seat is assembled, and synchronous sealing is achieved during assembly, ensuring convenient operation.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] Embodiment 1: The present invention provides a technical solution: a double-end isothermal cooling roller mechanism for sol coating, which is designed to address the problem that the cooling liquid in the existing cooling roller flows unidirectionally from one end of the roller body to the other end, and the unidirectional cooling method of the single flow channel of the cooling liquid easily leads to a temperature difference between the roller body cooling liquid inlet end and the roller body cooling liquid outlet end, resulting in uneven roller body temperature, which in turn easily causes 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 an offset state on the roller inner shell 2, and the first spiral channel 4 is used for directional transportation of the cooling liquid in a spiral manner from left to right on the roller inner shell 2, and the second spiral channel 5 is used for directional transportation of the cooling liquid in a spiral manner from right to left on the roller inner shell 2. The first spiral channel 4 and the second spiral channel 5 are coordinated to perform bidirectional flow transportation of the cooling liquid, so that the cooling liquid in the first spiral channel 4 and the cooling liquid in the second spiral channel 5 complement each other in temperature, even if the overall temperature of the roller outer shell 1 is arranged uniformly.

[0052] This technical solution: please refer to Figures 1-9 A double-end isothermal sol coating cooling roller mechanism comprises a roller shell 1, the left and right sides of the roller shell 1 are both open, a roller inner shell 2 is sealedly inserted into the cylinder cavity of the roller shell 1, and the left and right sides of the roller inner shell 2 are both open;

The main end shaft seat 3 is sealed at the left side of the roller inner shell 2, and the main end shaft seat 3 is used for the inlet of cooling liquid into the first spiral channel 4 and for the outlet of cooling liquid to the outside of the second spiral channel 5. The first spiral channel 4 is used for the directional transportation of cooling liquid from left to right on the roller inner shell 2, and the second spiral channel 5 is used for the directional transportation of cooling liquid from right to left on the roller inner shell 2. By transporting the cooling liquid in two-way channels, the overall temperature of the roller outer shell 1 is uniformly complemented. The secondary end shaft seat 6 is sealed at the right side of the roller inner shell 2, and the secondary end shaft seat 6 is used for the outlet of cooling liquid to the outside of the first spiral channel 4 and for the inlet of cooling liquid to the second spiral channel 5. The outside of the secondary end shaft seat 6 and the main end shaft seat 3 are both provided with a liquid supply mechanism 7 for leak-proof supply of cooling liquid.

[0054] Specifically, in this technical solution, the cooling liquid is transported from left to right on the roller inner shell 2 through the first spiral channel 4. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the outside of the main end shaft seat 3 is provided with a liquid supply mechanism 7 for leak-proof supply of coolant, and the liquid supply mechanism 7 includes a tube shell frame 9, a liquid inlet annular groove 10 and a liquid outlet annular groove 11. The section of the tube shell frame 9 away from the roller shell 1 is the outward section, and the liquid inlet annular groove 10 is provided on the outward section of the tube cavity wall of the tube shell frame 9. The section of the tube shell frame 9 toward the roller shell 1 is the inward section, and the liquid outlet annular groove 11 is provided on the inward section of the tube cavity wall of the tube shell frame 9. Since the lower side of the liquid inlet annular groove 10 is provided with a pipe connected thereto, The connecting portion is provided on the outer tube section of the shell frame 9 in an integrated structure. Since a connecting portion communicating with the liquid outlet annular groove 11 is provided on the lower side thereof, the connecting portion is provided on the inner tube section of the shell frame 9 in an integrated structure. The connecting portion is connected to the liquid supply pipeline of the coolant preparation device through the connecting portion in the liquid inlet annular groove 10, and is connected to the liquid return pipeline of the coolant preparation device through the connecting portion in the liquid outlet annular groove 11 (the above-mentioned coolant preparation device is prior art and is not described in the drawings of the specification);

[0055] Since the main liquid inlet channel 301 is opened at the lower part of the main end shaft seat 3, open flow channel openings are provided at both ends thereof, the flow channel opening in the main liquid inlet channel 301 facing one end of the roller inner shell 2 is the inward flow channel opening, and the flow channel opening in the main liquid inlet channel 301 facing away from one end of the roller inner shell 2 is the outward flow channel opening, the liquid inlet ring groove 10 is connected to the outward flow channel opening in the main liquid inlet channel 301 correspondingly, and since the two "O" rings 12 at the outward flow channel opening in the main liquid inlet channel 301 are symmetrically arranged about the center of the outward flow channel opening in the main liquid inlet channel 301, respectively, they are placed on both sides of the outward flow channel opening in the main liquid inlet channel 301, and since the two sealing components 13 at the liquid inlet ring groove 10 are symmetrically arranged about the center of the liquid inlet ring groove 10, and the two are relatively oriented. They are respectively placed on both sides of the liquid inlet ring groove 10, and are 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 through the two "O" rings 12 at the outward flow channel opening in the main liquid inlet channel 301, and are 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 through the two sealing components 13 at the liquid inlet ring groove 10. 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 to feed 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 is filled in the liquid inlet ring groove 10, it is transported into the main liquid inlet channel 301 through the outward flow channel opening in the main liquid inlet channel 301;

[0056] Since the roller inner shell 2 is sealed and inserted into the cylinder cavity of the roller outer shell 1, the left cylinder opening of the roller inner shell 2 is flush with the left cylinder opening of the roller outer shell 1, and since the main end shaft seat 3 is sealed at the left cylinder opening of the roller inner shell 2, and the main end shaft seat 3 is also sealed at the connection between the left cylinder opening in the roller inner shell 2 and the left cylinder opening in the roller outer shell 1, and since both ends of the first spiral channel 4 are in a closed state, a first liquid inlet 401 connected thereto is opened at its left end, and the first liquid inlet 401 is arranged on the lower cylinder wall of the left end of the roller inner shell 2, and is connected to the inward flow channel opening in the main liquid inlet channel 301 accordingly. After the first liquid inlet 401 is sealed and connected to the inward flow channel opening in the main liquid inlet channel 301, the coolant in the main liquid inlet channel 301 is transported into the first spiral channel 4 through the first liquid inlet 401;

[0057] Since the first spiral channel 4 is a one-way flow channel, it is recessed and opened on the roller inner shell 2. After the coolant enters the first spiral channel 4, it flows along the first spiral channel 4, so that the coolant is directed from left to right on the roller inner shell 2 in a spiral manner.

[0058] Since the roller inner shell 2 is sealed and inserted into the cylinder cavity of the roller outer shell 1, the right cylinder mouth of the roller inner shell 2 is flush with the right cylinder mouth of the roller outer shell 1, the secondary end shaft seat 6 is sealed and set at the right cylinder mouth of the roller inner shell 2, and the secondary end shaft seat 6 is also sealed and set at the connection between the right cylinder mouth in the roller inner shell 2 and the right cylinder mouth in the roller outer shell 1. Since the secondary liquid outlet 602 is opened at the upper part of the secondary end shaft seat 6, both ends of it are provided with open flow channel openings. The flow channel opening in the secondary liquid outlet 602 facing one end of the roller inner shell 2 is an inward flow channel opening, and the back of the secondary liquid outlet 602 is open. The flow channel opening at one end of the roller inner shell 2 is an outward flow channel opening. Since the right end of the first spiral channel 4 is provided with a first liquid outlet 402 connected thereto, the first liquid outlet 402 is placed on the upper wall of the right end of the roller inner shell 2 and is connected to the inward flow channel opening of the auxiliary liquid outlet channel 602. After the first liquid outlet 402 and the inward flow channel opening of the auxiliary liquid outlet channel 602 are sealed and connected, 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 channel opening of the auxiliary liquid outlet channel 602.

[0059] Since the exterior of the secondary end shaft seat 6 is also provided with a liquid supply mechanism 7 for leak-proof supply of coolant, the arrangement between the secondary end shaft seat 6 and the liquid supply mechanism 7 is the same as that between the main end shaft seat 3 and the liquid supply mechanism 7, and the sealing method between the secondary end shaft seat 6 and the liquid supply mechanism 7 is the same as that between the main end shaft seat 3 and the liquid supply mechanism 7, and since the two "O" rings 12 at the outward flow channel opening in the secondary liquid outlet 602 are symmetrically arranged about the center of the outward flow channel opening in the secondary liquid outlet 602, respectively placed on both sides of the outward flow channel opening in the secondary liquid outlet 602, and since the two sealing components 13 at the liquid outlet annular groove 11 are symmetrically arranged about the center of the liquid outlet annular groove 11, and the two are placed on both sides of the liquid outlet annular groove 11 in relative directions, through the two "O" rings 12 at the outward flow channel opening in the secondary liquid outlet 602 The ring 12 is used for the primary sealing treatment on both sides of the connection point 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 used for the secondary sealing treatment on both sides of the connection point between the liquid outlet ring groove 11 and the auxiliary liquid outlet channel 602. After completing the sealing treatment of the connection point between the liquid outlet ring groove 11 and the auxiliary liquid outlet channel 602, the auxiliary end shaft seat 6 is used to discharge the coolant to the outside of the first spiral channel 4. The liquid outlet ring groove 11 is connected to the outward flow channel opening in the auxiliary liquid outlet channel 602 in correspondence with the connection point. The coolant in the auxiliary liquid outlet channel 602 flows into the liquid outlet ring groove 11 through the outward flow channel opening 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 liquid pipeline in the coolant preparation device, realizing the circulation of the coolant from left to right in the first spiral channel 4.

[0060] Specifically, in this technical solution, the cooling liquid is transported from right to left on the roller inner shell 2 through the second spiral channel 5. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, according to the above, in the method of directional delivery of coolant through the first spiral channel 4, 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 to the outside of the first spiral channel 4. The delivery method used by the first spiral channel 4 is the same as the delivery method used by 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. In the method of directional delivery of coolant through the second spiral channel 5, 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 to the outside of the second spiral channel 5.

[0061] Since the auxiliary liquid inlet channel 601 is opened at the lower part of the auxiliary end shaft seat 6, both ends of the auxiliary liquid inlet channel 601 are provided with open flow channel openings, the flow channel opening in the auxiliary liquid inlet channel 601 facing the roller inner shell 2 is the inward flow channel opening, and the flow channel opening in the auxiliary liquid inlet channel 601 facing away from the roller inner shell 2 is the outward flow channel opening. The liquid inlet ring groove 10 is connected to the outward flow channel opening in the auxiliary liquid inlet channel 601 in a corresponding manner. In addition, the two "O" rings 12 at the outward flow channel opening in the auxiliary liquid inlet channel 601 are respectively used for the liquid inlet ring groove 10 and the auxiliary liquid inlet channel 601 on both sides of the connection. A primary sealing process is performed, and two sealing components 13 at the liquid inlet annular groove 10 are used for secondary sealing processes on both sides of the connection between the liquid inlet annular groove 10 and the auxiliary liquid inlet channel 601.

Furthermore, due to the sealing treatment between the secondary end shaft seat 6, the roller inner shell 2, and the roller outer shell 1, after the second liquid inlet 501 is sealed and communicated with the inward flow channel opening of the secondary liquid inlet channel 601, the coolant in the secondary liquid inlet channel 601 is transported into the second spiral channel 5 through the second liquid inlet 501.

[0069] Since hydraulic ring cavities 14 are provided at both side groove walls of the liquid inlet ring groove 10 and at both side groove walls of the liquid outlet ring groove 11, the two hydraulic ring cavities 14 at the liquid inlet ring groove 10 are symmetrically arranged about the center of the liquid inlet ring groove 10, and the two hydraulic ring cavities 14 are oppositely oriented and correspond to the two sealing components 13 in the middle. The hydraulic ring cavity 14 at the liquid outlet ring groove 11 is opened in the same manner as the hydraulic ring cavity 14 at the liquid inlet ring groove 10. Since the side of the "O" ring 12 facing away from the liquid inlet ring groove 10 is facing outward, the two sealing components 13 are respectively placed on the outward sides of the two "O" rings 12, and the two sealing components 13 are respectively matched with the two hydraulic ring cavities 14. The two sealing components 13 are respectively used for secondary sealing treatment on both sides of the connection between the liquid inlet ring groove 10 and the main liquid inlet channel 301;

[0070] Since the dynamic ring member 16 is movably clamped in the tube cavity wall of the tube shell frame 9 after being placed, and is movably sleeved on the outer side of the main end shaft seat 3, and since the sliding sealing ring 18 located on the outside is fixedly clamped on the outer ring wall of the dynamic ring member 16, it is sealed and fitted with the tube cavity wall of the tube shell frame 9, and the sliding sealing ring 18 located on the inside is fixedly clamped on the inner ring wall of the dynamic ring member 16, and is sealed and fitted with the outer wall of the main end shaft seat 3, the sealing process between the dynamic ring member 16 and the tube shell frame 9 is performed by the sliding sealing ring 18 located on the outside, and the sealing process between the dynamic ring member 16 and the main end shaft seat 3 is performed by the sliding sealing ring 18 located on the inside;

The elastic deformation of the first spring 17 is used to push the dynamic ring member 16 to slide in the tube cavity of the tube shell frame 9, and the dynamic ring member 16 drives the pressure sealing ring 19 to slide and press against the connection between the tube shell frame 9 and the main end shaft seat 3, so as to perform a sealing process between the tube shell frame 9 and the main end shaft seat 3;

[0072] Since the inner ring of the pressure sealing ring 19 is arranged in a conical ring structure on the side facing the hydraulic ring cavity 14, and since the pressure sealing ring 19 is fixedly clamped on the end of the dynamic ring member 16 after being installed, and the inner ring wall thereof is fitted on the main end shaft seat 3, and the conical ring end at the inner ring thereof extends into the hydraulic ring cavity 14, the coolant leaked from the sealing part of the "O" ring 12 fills into the hydraulic ring cavity 14, pushing the conical ring end at the inner ring of the pressure sealing ring 19, so that the inner ring wall of the pressure sealing ring 19 is sealed and pressed against the main end shaft seat 3.

[0073] Specifically, in this technical solution, the cooling roller mechanism operates to cool the sol coating material. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, a spiral sealing strip 8 is provided between the first spiral channel 4 and the second spiral channel 5. Since the spiral sealing strip 8 is fixedly clamped on the roller inner shell 2 after installation, 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 channel 4 and the second spiral channel 5, so that the first spiral channel 4 and the second spiral channel 5 respectively form independent flow channels, assisting the two-way flow transportation of the coolant;

[0074] Since the specifications and dimensions of the first spiral channel 4 are the same as those of the second spiral channel 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 direction, and since the first spiral channel 4 and the second spiral channel 5 are arranged in a staggered state, the first spiral channel 4 is used for directional transportation of coolant in a spiral manner from left to right, and the second spiral channel 5 is used for directional transportation of coolant in a spiral manner from right to left, the coolant in the first spiral channel 4 and the coolant in the second spiral channel 5 are staggered to achieve uniform temperature complementation between the two, thereby achieving uniform temperature distribution on the entire cylinder of the roller outer shell 1 and ensuring that both ends of the roller outer shell 1 are set in a isothermal state;

The central position of the outward end of the main end shaft seat 3 is provided with an integrated structure shaft column part, wherein the horizontal central axis of the shaft column part coincides with the horizontal central axis of the main end shaft seat 3. Since the end of the secondary end shaft seat 6 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 secondary end shaft seat 6 is arranged in a parallel state on the right side of the roller shell 1 after being installed, and the two are on the same horizontal central axis. The central position of the outward end of the secondary end shaft seat 6 is provided with an integrated structure shaft column part, wherein the shaft The horizontal center axis of the column coincides with the horizontal center axis of the secondary end shaft seat 6. After the cooling roller mechanism is installed, the central axis column of the main end shaft seat 3 and the central axis column of the secondary end shaft seat 6 are respectively rotatably connected to the frames on both sides of the production line, and a driving device is installed on either the central axis column of the main end shaft seat 3 or the central axis column of the secondary end shaft seat 6 (the above-mentioned production line frames and driving devices are all prior art and are not described in the drawings of the specification). The sol coating material is overlapped on the roller shell 1, and the central axis column of the main end shaft seat 3 or the central axis column of the secondary end shaft seat 6 is driven by the driving device to make the main end shaft seat 3, the roller shell 1, the roller inner shell 2 and the secondary end shaft seat 6 rotate synchronously, that is, the cooling roller mechanism rotates to cool the sol coating material;

[0076] Since the tube openings on both sides of the shell and tube frame 9 are both set in an open state, and bearings are clamped at the tube openings on both sides, and since the inward end of the main end shaft seat 3 is provided with an inward limiting ring of an integrated structure, its outward end is clamped and fixedly connected with an outward limiting ring through bolts, and since the inward end of the secondary end shaft seat 6 is provided with an inward limiting ring of an integrated structure, its outward end is clamped and fixedly connected with an outward limiting ring through bolts, after the shell and tube frame 9 is placed in the main end shaft seat 3, the shell and tube frame 9 The movable sleeve is arranged on the main end shaft seat 3, and the two bearings in the shell frame 9 are respectively clamped at both ends of the main end shaft seat 3. The shell frame 9 is positioned on the main end shaft seat 3 in a movable state through the inward limiting ring and the outward limiting ring in the main end shaft seat 3. The placement method of the shell frame 9 in the secondary end shaft seat 6 is the same as that of the shell frame 9 in the main end shaft seat 3. The shell frame 9 is positioned on the secondary end shaft seat 6 in a movable state through the inward limiting ring and the outward limiting ring in the secondary end shaft seat 6.

[0077] Since the liquid supply mechanism 7 is sealed and rotatable on the main end shaft seat 3, the main end shaft seat 3 is connected to the middle tube shell frame 9 in a rotatable manner, and the liquid supply mechanism 7 is also sealed and rotatable on the secondary end shaft seat 6, so that the secondary end shaft seat 6 is connected to the middle tube shell frame 9 in a rotatable manner. In addition, since the front and rear sides of the tube shell frame 9 are vertically provided with an integrated structure connecting frame, after the cooling roller mechanism is installed, the connecting frame of the tube shell frame 9 on the main end shaft seat 3 and the connecting frame of the tube shell frame 9 on the secondary end shaft seat 6 are respectively fixedly connected to the two side frames of the production line. When the main end shaft seat 3, the roller outer shell 1, the roller inner shell 2 and the secondary end shaft seat 6 rotate synchronously, the tube shell frame 9 will not affect the rotation of the main end shaft seat 3 or the secondary end shaft seat 6, and at the same time, the tube shell frame 9 will not rotate with the main end shaft seat 3 or the secondary end shaft seat 6, that is, it will not affect the liquid supply pipeline and the return pipeline in the cooling liquid preparation device.

[0078] Example 2: This invention is based on Example 1. Figure 10-13 According to the technical solution shown, after the cooling roller is used for a long time, the coolant will easily cause impurities to be deposited in the flow channel of the cooling roller, resulting in the formation of a scale layer in the flow channel. If it is not cleaned in time, the scale layer will cause blockage, which will directly affect the flow of the coolant and thus affect the cooling effect. The existing cooling rollers are mostly integrated structures. To address the problem that the existing cooling rollers are not easy to disassemble and the scale layer in the flow channel is not easy to clean, the main end shaft seat 3 is docked and installed on the left side of the roller shell 1, and the secondary end shaft seat 6 is docked and installed on the right side of the roller shell 1. The main end shaft seat 3 and the secondary end shaft seat 6 are fixedly assembled through the threaded connection between the bolt rod 21 and the fixing cap 22. The roller inner shell 2 is clamped and fixed in the roller shell 1 through the main end shaft seat 3 and the secondary end shaft seat 6. Conversely, the main end shaft seat 3, the secondary end shaft seat 6 and the roller inner shell 2 can be conveniently disassembled on the roller shell 1, and are easy to clean after disassembly.

[0079] Specifically, in this technical solution, during the assembly operation of the cooling roller mechanism, according to Figure 10 、 Figure 11 and Figure 12 As shown, since the central position of the main end shaft seat 3 toward the inner end is horizontally provided with an integrated structure square plug 20, and the two are on the same horizontal central axis, and since the middle position of the square plug 20 in the main end shaft seat 3 is horizontally provided with an integrated structure bolt rod 21, the bolt rod 21 and the main end shaft seat 3 are on the same horizontal central axis, after the main end shaft seat 3 is placed, the inward limit ring thereof is stuck and pressed against the left tube opening of the roller outer shell 1, and the inward end plug thereof is pressed against the left tube opening of the roller inner shell 2, and the bolt rod 21 is inserted through the cylinder cavity of the roller inner shell 2 and the square plug 20 in the secondary end shaft seat 6 and inserted into the secondary end shaft seat 6;

[0080] Since the central position of the inner end of the secondary end shaft seat 6 is horizontally provided with an integrated square plug 20, the two are on the same horizontal central axis. After the secondary end shaft seat 6 is placed, the inward limiting ring thereof is plugged and pressed against the right side opening of the roller outer shell 1, and the inward end thereof is plugged and pressed against the right side opening of the roller inner shell 2. The end of the bolt rod 21 is threadedly fixed with a fixing cap 22. After the fixing cap 22 is screwed and rotated on the bolt rod 21, it presses on the secondary end shaft seat 6 for limiting locking of the secondary end shaft seat 6. By the connection between the fixing cap 22 and the bolt rod 21, the secondary end shaft seat 6 and the main end shaft seat 3 are relatively displaced, and the roller inner shell 2 is clamped and fixed in the roller outer shell 1.

[0081] According to the above, conversely, unscrew and loosen the threaded connection between the fixing cap 22 and the bolt rod 21, release the fixation between the main end shaft seat 3 and the secondary end shaft seat 6, and disassemble the main end shaft seat 3, the secondary end shaft seat 6 and the roller inner shell 2 on the roller outer shell 1, which is easy to clean after disassembly.

[0082] At the same time, in the above technical solution, according to Figure 11 、 Figure 12 and Figure 13 As shown, the joints between the main end shaft seat 3 and the roller shell 1 and the joints between the secondary end shaft seat 6 and the roller shell 1 are both provided with sealing ring gaskets 23 for sealing. The sealing method of the sealing ring gasket 23 at the joints between the main end shaft seat 3 and the roller shell 1 is the same as the sealing method of the sealing ring gasket 23 at the joints between the secondary end shaft seat 6 and the roller shell 1. As far as the sealing operation of the sealing ring gasket 23 at the joints between the main end shaft seat 3 and the roller shell 1 is concerned;

[0083] Since the sealing ring gasket 23 in the main end shaft seat 3 is fixedly clamped on the inward limiting ring in the main end shaft seat 3, after the main end shaft seat 3 is docked with the roller shell 1, the sealing ring gasket 23 is sealed and pressed against the connection position of the left side tube opening in the roller shell 1 and the left side tube opening in the roller inner shell 2 to perform sealing.

[0084] At the same time, in the above technical solution, according to Figure 11 、 Figure 12 and Figure 13 As shown, connecting rings of an integrated structure are provided on the left and right sections of the cylinder cavity wall of the roller inner shell 2, and pressure sealing mechanisms 24 for sealing are provided at the joints between the main end shaft seat 3 and the roller inner shell 2 and the joints between the secondary end shaft seat 6 and the roller inner shell 2. The two pressure sealing mechanisms 24 are respectively arranged at the left and right ends of the roller inner shell 2 in opposite directions, and the pressure sealing mechanism 24 on the left and the pressure sealing mechanism 24 on the right correspond to the main end shaft seat 3 and the secondary end shaft seat 6 respectively. The sealing method of the pressure sealing mechanism 24 at the joint of the main end shaft seat 3 and the roller inner shell 2 is the same as the sealing method of the pressure sealing mechanism 24 at the joint of the secondary end shaft seat 6 and the roller inner shell 2. As far as the sealing operation of the pressure sealing mechanism 24 at the joint of the main end shaft seat 3 and the roller inner shell 2 is concerned;

[0085] Since the two pressing seal mechanisms 24 are connected to the bolt rod 21 in a movable penetrating manner, when the main end shaft seat 3 and the secondary end shaft seat 6 are assembled, the insertion of the bolt rod 21 is not affected;

[0086] Since the end of the fixed tube seat 25 facing the roller inner shell 2 is the inward end, and the end of the fixed tube seat 25 facing away from the roller inner shell 2 is the outward end, a positioning square groove adapted to the square plug 20 is opened at the outward end of the fixed tube seat 25.

A section of the linkage frame 28 facing the fixed tube seat 25 is an inward frame, and a section of the linkage frame 28 facing the fixed tube seat 25 is an outward frame. Since the middle part of the linkage frame 28 is rotatably connected with a shaft column, the linkage frame 2 After installation, the movable card is set in the empty groove of the fixed tube seat 25, wherein the inward frame body is inserted through the hollow groove of the fixed tube seat 25 and extends into the positioning square groove of the fixed tube seat 25, and the two ends of the shaft column are respectively plugged in and fixedly connected to the groove walls on both sides of the fixed tube seat 25 by bolts. The linkage frame 28 is assisted by the shaft column to form a rotating structure on the fixed tube seat 25. After the square plug 20 is inserted into the positioning square groove of the fixed tube seat 25, the square plug 20 is connected to the inward frame body of the linkage frame 28 by a pressing method, pushing the linkage frame 28 to move, so that the linkage frame 28 is turned over at the outward end of the fixed tube seat 25;

[0088] Since the end of the movable tube seat 26 facing the roller inner shell 2 is the inward end, and the end of the movable tube seat 26 facing away from the roller inner shell 2 is the outward end, the inward end of the movable tube seat 26 is provided with a through-state empty slot, wherein the empty slots are arranged in a circular array with the tube center of the movable tube seat 26 as the center, and pin rods are inserted into the empty slots and fixedly connected by bolts. Moreover, since the outward frame body of the linkage frame 28 is provided with a through-shaped slide slot, after the linkage frame 28 is placed, the outward frame body of the linkage frame 28 is movably inserted into the empty slot of the movable tube seat 26, and the pin rod in the movable tube seat 26 is movably inserted through the slide slot of the outward frame body of the linkage frame 28. After the linkage frame 28 is turned over, the outward frame body of the linkage frame 28 is connected to the pin rod in the movable tube seat 26 in a sliding manner. Through sliding cooperation, the movable tube seat 26 is moved.

[0089] Since the fixed pipe seat 25 is inserted into the cylinder cavity of the roller inner shell 2 after being placed, and it is fixedly connected to the connecting ring in the roller inner shell 2 by bolts, the middle part of the fixed pipe seat 25 is provided with a middle ring disc portion of an integrated structure, the inward end of the fixed pipe seat 25 is clamped and fixedly connected to the side ring disc portion by bolts, and since the inward end of the movable pipe seat 26 is clamped and fixedly connected to the side ring disc portion by bolts, after the movable pipe seat 26 is placed, the side ring disc portion is movably sleeved on the fixed pipe seat 25, and the middle ring disc portion of the fixed pipe seat 25 is movably clamped in the tube cavity of the movable pipe seat 26. Through the limitation of the side ring disc portion in the fixed pipe seat 25, the movable pipe seat 26 is positioned on the fixed pipe seat 25 in an active state. A second spring 27 is installed at the sliding connection between the fixed pipe seat 25 and the movable pipe seat 26. After being installed, the second spring 27 is movably sleeved on the fixed pipe seat 25 and placed in the tube cavity of the movable pipe seat 26. One end of the second spring 27 presses against the middle ring disk of the fixed pipe seat 25, and the other end presses against the side ring disk of the movable pipe seat 26. After being toggled, the movable pipe seat 26 slides on the fixed pipe seat 25, causing the second spring 27 to be squeezed and elastically deformed. In addition, the elastic deformation of the second spring 27 is reset, causing the movable pipe seat 26 to reset and slide on the fixed pipe seat 25.

[0090] Since the outward end of the movable pipe seat 26 is fixedly clamped with a sealing ring sleeve 29, the structural shape of the inward end of the main end shaft seat 3 is adapted to the sealing ring sleeve 29. After the movable pipe seat 26 slides, it drives the sealing ring sleeve 29 to move synchronously, so that the sealing ring sleeve 29 is pressed and sealed at the connection between the roller inner shell 2 and the main end shaft seat 3 to perform sealing treatment.
