Description

Technical Field

[0001] The invention relates to the technical field of film material production, in particular to a cooling and shaping mechanism for producing a heat-insulating film. Background Art

[0002] During the continuous production of thermal insulation film, the film material formed at high temperature needs to be cooled quickly to achieve morphological solidification, inhibit changes in crystallinity and improve dimensional stability. If the cooling rate is insufficient or the temperature distribution is uneven, it is easy to cause the film material to shrink and deform, the surface finish to deteriorate, and thermal stress to remain. For this reason, the cooling roller becomes the core equipment of the production line. It directly contacts the roller surface through the internal circulating cooling medium, and efficiently conducts away the heat conducted by the film material.

[0003] Traditional cooling rollers usually adopt a hollow roller structure. Cooling water is injected into the roller cavity through the axial water inlet pipe and flows unidirectionally along the axial flow channel inside the roller body. During the axial migration process, the water flow is thrown onto the roller wall by the centrifugal force when the cooling roller rotates, absorbing heat and achieving roller surface cooling through thermal convection.

[0004] However, when the cooling water flows axially, the flow section that first contacts the high-temperature area of ​​the film material continues to absorb heat and heat up, causing the subsequent flow sections of the cooling water to form an axial temperature gradient due to heat accumulation, resulting in differences in the heat dissipation capacity of different flow sections of the cooling roller, and thus causing uneven cooling of the thermal insulation film. In addition, the cooling water only relies on its own flow and the turbulence formed by the rotation of the cooling roller to exchange heat with the roller wall, resulting in weak disturbance of the cooling water flow and poor convection efficiency, resulting in low heat transfer efficiency.

[0008] The piston rod pushes the water flow to the inner side of the cooling roller through reciprocating radial movement, and the driving rod drives the spiral blades and the vortex plate to rotate to radially separate the heated water flowing through the inner side of the cooling roller.

[0009] Preferably, a water outlet pipe is fixedly installed on the inner side of the cooling roller and is arranged one-to-one with the driving rod. The left end of the water outlet pipe is closed and the right end extends to the outside of the cooling roller. Several three-way pipes are fixedly connected and connected to the water outlet pipe. The three-way pipes are rotatably connected and connected with the vortex plates at the corresponding positions.

[0010] Preferably, the left and right ends of the vortex plate are plate-shaped structures with a through hole in the middle. The vortex plate is rotatably connected and communicated with the tee pipe at the corresponding position through the through hole on its plate-shaped structure. The left side of the leftmost tee pipe and the right side of the rightmost tee pipe are both closed by resting on the isolation tube.

[0011] Preferably, a plurality of water-deflecting plates are fixedly installed at equal intervals on the outer side of the vortex plate along the circumference of the corresponding driving rod, and the spiral blades are in a symmetrical structure with opposite left and right spiral directions.

[0012] Preferably, a transmission gear is fixedly mounted on the left end of the driving rod, and a fixed gear ring that meshes with all the transmission gears at the same time is fixedly mounted on the left support.

[0013] Preferably, the water inlet pipe is provided with several groups of water holes at equal intervals along its axial direction, and each group is composed of several water holes arranged at equal intervals along the circumference of the water inlet pipe. A water pusher fan is fixedly installed on the inner wall of the isolation cylinder at the position corresponding to each group of water holes, and the deflection angles of two adjacent blades of the water pusher fan are opposite.

[0014] Preferably, a plurality of track sleeves are fixedly installed on the outer side of the water inlet pipe at equal intervals along its axial direction, and a flower-shaped groove is provided on the track sleeve. The end of the piston column close to the axis of the cooling roller is slidably connected to the flower-shaped groove through a T-shaped rod.

[0015] Preferably, the portion of the guide sleeve away from the axis of the cooling roller is in a conical structure, and a plurality of spiral grooves are provided on the inner side surface of the conical structure of the guide sleeve at equal intervals along the circumference thereof.

[0016] Preferably, a plurality of fixed sleeves are fixedly installed at equal intervals along the axial direction on the outer side of the water inlet pipe, a guide groove is provided on the fixed sleeve, and a plurality of knocking rods corresponding to the guide sleeves are provided on the isolation cylinder along its radial sliding direction, and the part of the knocking rod close to the axis of the cooling roller is slidably connected to the guide groove.

[0017] Preferably, the guide groove is composed of a plurality of wedge-shaped grooves arranged at equal intervals along the circumference of the fixing sleeve, and a coil spring is provided between the knocking rod and the isolation cylinder.

[0018] The beneficial effects of the present invention are: 1. The present invention adopts a piston column that moves back and forth radially along the isolation cylinder in conjunction with a guide sleeve to actively impact the cooling water on the inside of the isolation cylinder onto the inner wall of the cooling roller, so that the cooling water directly contacts the high-temperature roller surface radially for efficient heat absorption. At the same time, the vortex plate is driven to rotate by the driving rod to separate and discharge the heated cooling water radially inward along the cooling roller, breaking the traditional axial unidirectional flow mode, effectively eliminating the temperature gradient of the cooling water formed in the axial direction of the cooling roller, and ensuring that the heat dissipation capacity of each section of the roller surface is uniform.

[0019] 2. The present invention adopts the conical structure of the guide sleeve to gather and accelerate the water flow to impact the inner wall of the cooling roller. While enhancing the contact efficiency between the low-temperature cooling water and the roller surface, it forms a stagnant water layer near the roller wall with strong turbulence disturbance. Combined with the multi-directional stirring effect of the water flow by the water deflector plate outside the vortex plate, the convective heat exchange intensity between the cooling water and the inner wall of the cooling roller is significantly improved, greatly improving the heat transfer efficiency.

[0020] 3. The present invention adopts a water pusher fan that rotates synchronously with the isolation cylinder. Through the unique design of the opposite deflection angles of its adjacent fan blades, the cooling water flowing out of the water hole of the water inlet pipe is quickly diffused in two directions to the entire circumference of the inner cavity of the isolation cylinder, thereby achieving uniform distribution of cooling water inside the isolation cylinder, providing a basis for the piston column to evenly transport cooling water to the inner wall of the cooling roller, and fundamentally and effectively ensuring the consistency of the temperature of the inner wall of the cooling roller.

[0021] 4. The present invention uses a knocking rod to cooperate with the guide groove on the fixed sleeve. When the isolation cylinder rotates, the knocking rod is driven to periodically knock on the inner wall of the cooling roller in the radial direction. Mechanical vibration is used to peel off the scale adhering to the inner wall of the cooling roller, effectively maintaining the cleanliness of the roller wall of the cooling roller and preventing the scale layer from reducing the heat conduction efficiency.

[0034] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0035] See Figure 1 and Figure 2 A cooling and shaping mechanism for producing thermal insulation film comprises two supports 1 arranged symmetrically on the left and right, a cooling roller 2 is arranged to rotate together between the two supports 1, an isolation cylinder 3 coaxially arranged with the cooling roller 2 is fixedly installed on the inner side of the cooling roller 2, and a water inlet pipe 4 inserted into the coaxial interior of the isolation cylinder 3 is fixedly installed on the left support 1. The mechanism also comprises a water inlet unit 5 for forced impact water inlet and a water outlet unit 6 for active turbulent flow and drainage.

[0036] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7The water inlet unit 5 includes several groups of guide sleeves 51 fixedly installed on the isolation cylinder 3 at equal intervals along the axial direction. Each group is composed of several guide sleeves 51 arranged at equal intervals along the circumference of the isolation cylinder 3. The guide sleeves 51 are arranged along the radial direction of the isolation cylinder 3. A piston column 52 is provided on the inner side of the guide sleeve 51 for sliding along its axial direction. A one-way valve 53 is fixedly installed on the coaxial position of the piston column 52.

[0037] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The water outlet unit 6 includes a plurality of drive rods 61 rotatably connected to the isolation cylinder 3 and distributed at equal intervals along the circumference thereof. A plurality of spiral blades 62 are fixedly installed at equal intervals along the axial direction of the drive rod 61 , and a vortex plate 63 is fixedly installed on the outer side of the spiral blade 62 .

[0038] When the insulation film needs to be cooled and shaped, the two supports 1 are first fixedly installed on the insulation film production line, so that the insulation film that needs to be cooled is wrapped around the outer roller wall of the cooling roller 2, and then the left end of the water inlet pipe 4 is connected to the cooling water supply device. The cooling water is passed through the water inlet pipe 4 through the water supply device to fill the inner cavity of the isolation cylinder 3, and then the cooling roller 2 is driven to rotate by the existing driving device, so that the linear speed of the cooling roller 2 is consistent with the moving speed of the insulation film.

[0039] When the cooling roller 2 rotates, its outer wall is in continuous contact with the thermal insulation film, and the piston column 52 and the guide sleeve 51 rotate simultaneously with the cooling roller 2, and the piston column 52 moves back and forth along the axial direction of the guide sleeve 51. When the piston column 52 is close to the axis of the cooling roller 2, the one-way valve 53 opens, so that the cooling water in the inner cavity of the isolation cylinder 3 flows into the guide sleeve 51 through the one-way valve 53. When the piston column 52 is away from the axis of the cooling roller 2, the one-way valve 53 closes, so that the piston column 52 pushes the cooling water in the guide sleeve 51 to radially impact the inner roller wall of the cooling roller 2, so that the heat on the thermal insulation film is quickly transferred to the cooling water at the inner roller wall of the cooling roller 2 through the roller wall of the cooling roller 2, so that the cooling water at the inner roller wall of the cooling roller 2 is heated.

[0040] As the isolation cylinder 3 rotates with the cooling roller 2, the isolation cylinder 3 drives the vortex plate 63 on it to revolve synchronously. During this process, the vortex plate 63 and the spiral blades 62 on it rotate synchronously, so that the rotating vortex plate 63 radially winds up the heated cooling water at the inner roller wall of the cooling roller 2, and then the heated cooling water is actively discharged from the inner roller wall of the cooling roller 2 through the rotating spiral blades 62.

[0041] Through active radial water inlet and active radial drainage, the axial flow of cooling water at the inner roller wall of the cooling roller 2 is effectively reduced, ensuring the temperature consistency of each section on the cooling roller 2, thereby improving the effect of cooling the thermal insulation film. The active water inlet and outlet effectively improves the fluidity of the cooling water, prevents cooling water from stagnation, and ensures that the temperature change of the roller wall of the cooling roller 2 is small.

[0042] In order to quickly expand the cooling water flowing out of the water inlet pipe 4 to the entire inner cavity of the isolation cylinder 3 and ensure that the temperature of the cooling water delivered by each piston rod 52 is consistent, the present invention makes the following design: Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 and Figure 10 Several groups of water holes are arranged at equal intervals along the axial direction of the water inlet pipe 4, and each group is composed of several water holes arranged at equal intervals along the circumference of the water inlet pipe 4. A water pusher fan 54 is fixedly installed on the inner wall of the isolation cylinder 3 at the position corresponding to each group of water holes, and the deflection angles of the two adjacent blades of the water pusher fan 54 are opposite.

[0043] When the cooling water inside the water inlet pipe 4 is discharged from the water hole on it, the isolation cylinder 3 drives the water-pushing fan 54 on it to rotate synchronously, so that the water-pushing fan 54 pushes the cooling water in both directions along the axial direction of the isolation cylinder 3 through the fan blades with opposite deflection angles on it, thereby allowing the cooling water to quickly diffuse to the entire circumference of the inner cavity of the isolation cylinder 3, achieving uniform distribution of the cooling water inside the isolation cylinder 3, and then achieving consistency in the temperature of the cooling water delivered by each piston column 52, thereby ensuring the consistency of the roller wall temperature of the cooling roller 2.

[0044] See Figure 2 、 Figure 4 and Figure 7 A plurality of track sleeves 55 are fixedly installed on the outside of the water inlet pipe 4 at equal intervals along its axial direction. A flower groove is opened on the track sleeve 55. The end of the piston column 52 close to the axis of the cooling roller 2 is slidably connected to the flower groove through a T-shaped rod 551.

[0045] When the isolation cylinder 3 starts to rotate, the isolation cylinder 3 drives the piston column 52 to move synchronously through the guide sleeve 51, and the piston column 52 drives the T-shaped rod 551 to move along the flower-shaped groove of the track sleeve 55, so that the T-shaped rod 551 drives the piston column 52 to move back and forth along the radial direction of the isolation cylinder 3.

[0046] In order to prevent the scale of cooling water from adhering to the inner roller wall of the cooling roller 2, which causes the roller wall of the cooling roller 2 to become thicker and the heat conduction efficiency to decrease, the present invention makes the following design: Figure 2 、 Figure 3 、 Figure 4 and Figure 8A number of fixed sleeves 56 are fixedly installed on the outside of the water inlet pipe 4 along its axial direction at equal intervals. A guide groove is provided on the fixed sleeve 56. A number of knocking rods 561 corresponding to the guide sleeve 51 are slidingly provided on the isolation cylinder 3 along its radial direction. The part of the knocking rod 561 close to the axis of the cooling roller 2 is slidably connected in the guide groove. The guide groove is composed of a number of wedge-shaped grooves arranged at equal intervals along the circumference of the fixed sleeve 56. A coil spring is provided between the knocking rod 561 and the isolation cylinder 3.

[0047] When the isolation cylinder 3 starts to rotate, the isolation cylinder 3 drives the knocking rod 561 to move synchronously, so that the knocking rod 561 moves along the trajectory of the guide groove. When the end of the knocking rod 561 close to the axis of the isolation cylinder 3 contacts the wedge surface of the wedge groove, the knocking rod 561 moves along the wedge surface of the wedge groove toward the direction close to the axis of the isolation cylinder 3 and compresses the coil spring. When the knocking rod 561 moves to a section of the wedge groove radially arranged along the isolation cylinder 3, the coil spring pushes the knocking rod 561 to move away from the axis of the isolation cylinder 3 through its own elastic force, so that the knocking rod 561 periodically knocks the inner wall of the cooling roller 2 radially, and uses mechanical vibration to peel off the scale adhered to the inner wall of the cooling roller 2, effectively maintaining the cleanliness of the roller wall of the cooling roller 2, and preventing the scale layer from reducing the heat conduction efficiency.

[0048] In order to make the piston rod 52 push the cooling water inside the guide sleeve 51 to quickly contact the inner roller wall of the cooling roller 2, so as to ensure that the cooling water can effectively cool the cooling roller 2, and at the same time actively disturb the cooling water at the inner roller wall of the cooling roller 2 to enhance the convection effect of the cooling water, the present invention makes the following design: Figure 4 and Figure 7 The portion of the guide sleeve 51 away from the axis of the cooling roller 2 is in a conical structure, and a plurality of spiral grooves are provided on the inner side surface of the conical structure of the guide sleeve 51 at equal intervals along its circumference.

[0049] When the piston rod 52 pushes the cooling water inside the guide sleeve 51 outward, when the cooling water moves to the conical structure of the guide sleeve 51, the diameter of the guide sleeve 51 is reduced, which makes the water flow speed faster, so that the cooling water inside the guide sleeve 51 can quickly impact the inner roller wall of the cooling roller 2, and maximize the use of low-temperature cooling water to cool the thermal insulation film. At the same time, when the water flow is pushed out of the guide sleeve 51, the guide sleeve 51 guides the water flow through the spiral groove on its conical structure, so that the cooling water rotates and flows out, thereby disturbing the cooling water at the inner roller wall of the cooling roller 2, and enhancing the convection effect of the cooling water.

[0050] See Figure 1 and Figure 2 A transmission gear 611 is fixedly installed on the left end of the driving rod 61, and a fixed gear ring 612 that meshes with all the transmission gears 611 at the same time is fixedly installed on the left support 1.

[0051] See Figure 5A plurality of water-deflecting plates 631 are fixedly installed at equal intervals along the circumference of the corresponding driving rod 61 on the outer side of the vortex plate 63, and the spiral blades 62 are symmetrical structures with opposite left and right spiral directions.

[0052] See Figure 2 、 Figure 4 、 Figure 5 and Figure 6 A water outlet pipe 64 is fixedly installed on the inner side of the cooling roller 2 and is arranged one-to-one with the driving rod 61. The left end of the water outlet pipe 64 is closed and the right end extends to the outside of the cooling roller 2. Several three-way pipes 641 are fixedly connected and connected to the water outlet pipe 64. The three-way pipe 641 is rotatably connected and connected with the vortex plate 63 at the corresponding position.

[0053] Continue reading Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The left and right ends of the vortex plate 63 are plate-shaped structures with a through hole in the middle. The vortex plate 63 is rotatably connected and communicated with the three-way pipe 641 at the corresponding position through the through hole on its plate-shaped structure. The left side of the three-way pipe 641 at the leftmost part and the right side of the three-way pipe 641 at the rightmost part are both closed by resting on the isolation tube 3.

[0054] When the cooling roller 2 and the isolation cylinder 3 start to rotate, the isolation cylinder 3 drives the driving rod 61 thereon to rotate synchronously, so that the driving rod 61 drives the transmission gear 611 to rotate along the circumference of the fixed gear ring 612, thereby causing the transmission gear 611 to rotate through the engagement of the fixed gear ring 612, and then the driving rod 61 drives the spiral blades 62 and the vortex plate 63 at the corresponding positions to rotate. The vortex plate 63 reels the heated cooling water along the radial direction of the cooling roller 2 to its center position, and then the spiral blades 62 push it toward the two ends of the vortex plate 63, so that the cooling water actively flows through the tee pipe 641 to the water outlet pipe 64, thereby realizing the active discharge of the heated cooling water by the water outlet pipe 64.

[0055] The above-mentioned active radial drainage method is used to prevent the cooling water after heating from being retained on the inner roller wall of the cooling roller 2, thereby affecting the heat conduction of the cooling roller 2 to the insulation film. When the vortex plate 63 rotates, it drives the water deflector 631 on its outer side to further stir the water flow, significantly improving the convective heat exchange intensity between the cooling water and the inner wall of the cooling roller 2, and greatly improving the heat transfer efficiency.

[0056] It should be noted that the newly added structures of the present invention, such as the guide sleeve 51, piston column 52, and vortex plate 63, are all realized by basic industrial components. The guide sleeve 51, vortex plate 63, etc. are made by conventional casting or sheet metal processing (such as stainless steel milling, aluminum bending), the piston column 52, T-rod 551 and other moving parts are medium carbon steel turning parts, and the tee pipe 641 is modified based on standard pipe fittings. All parts processing relies on general machine tools (such as milling machines, wire cutting), and there are no precise tolerance requirements. The whole machine is realized through modular assembly, which greatly reduces the assembly complexity.

[0057] Moreover, the cost of newly added components accounts for an extremely low proportion, far lower than the waste film loss caused by uneven cooling. The entire machine is designed with mechanical transmission, and no additional power source is required, thus avoiding excessive increase in energy consumption. At the same time, the improvement in cooling uniformity and the reduction in scaling rate brought about by the present invention make the overall benefit far higher than the incremental cost of the structure, fully meeting the practical requirements of industrial mass production and long-term use.
