Description

Technical Field

[0001] This invention relates to the field of membrane material production technology, specifically a cooling and shaping mechanism for heat insulation film production. Background Technology

[0002] In the continuous production process of heat insulation film, the high-temperature formed film material needs to be cooled quickly to achieve morphological solidification, suppress 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, reduce the surface smoothness and leave thermal stress residue. Therefore, the cooling roller has become the core equipment of the production line. It directly contacts the roller surface through the internal circulating cooling medium to efficiently remove the heat conducted by the film material.

[0003] Traditional cooling rollers typically employ a hollow roller body structure. Cooling water is injected into the roller cavity through an axial inlet pipe and flows unidirectionally along the axial flow channel inside the roller body. During the axial migration, the water is thrown onto the roller wall by the centrifugal force of the rotating cooling roller to absorb heat, and the roller surface is cooled through thermal convection.

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

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a cooling and shaping mechanism for producing heat insulation film, including two supports arranged symmetrically on the left and right, a cooling roller is rotatably arranged between the two supports, an isolation cylinder arranged coaxially with the cooling roller is fixedly installed on the inner side of the cooling roller, and a water inlet pipe inserted into the coaxial interior of the isolation cylinder is fixedly installed on the left support. The mechanism also includes a water inlet unit for forced impact water inlet and a water outlet unit for active turbulent drainage.

[0006] The water inlet unit includes several groups of guide sleeves that are fixedly installed at equal intervals along the axial direction of the isolation cylinder. Each group consists of several guide sleeves that are arranged at equal intervals along the circumference of the isolation cylinder. The guide sleeves are arranged radially along the isolation cylinder. A piston column is slidably installed on the inner side of the guide sleeve along its axial direction. A one-way valve is fixedly installed on the piston column at the same axial position.

[0007] The water outlet unit includes several drive rods that are rotatably connected to the isolation cylinder and are evenly distributed along its circumference. Several helical blades are fixedly installed at equal intervals along the axial direction on the outside of the drive rods, and a vortex plate is fixedly installed on the outside of the helical blades.

[0008] The piston rod pushes the water flow to impact the inner surface of the cooling roller through reciprocating radial movement. The drive rod drives the spiral blades and vortex plates to rotate and radially separate the heated water flowing through the inner surface of the cooling roller.

[0009] Preferably, a water outlet pipe is fixedly installed on the inner side of the cooling roller, which is arranged in a one-to-one correspondence with the drive rod. The left end of the water outlet pipe is closed and the right end extends to the outside of the cooling roller. Several T-pipes are fixedly connected and connected to the water outlet pipe. The T-pipes are rotatably connected and connected to the vortex plate at the corresponding position.

[0010] Preferably, the left and right ends of the vortex plate are plate-shaped structures with through holes in the middle. The vortex plate is rotatably connected and communicated with the corresponding three-way pipes through the through holes in its plate-shaped structure. The left side of the leftmost three-way pipe and the right side of the rightmost three-way pipe are both closed by abutting against the isolation cylinder.

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

[0012] Preferably, a transmission gear is fixedly installed on the left end of the drive rod, and a fixed gear ring that meshes with all the transmission gears is fixedly installed on the support on the left.

[0013] Preferably, the water inlet pipe is provided with several sets of water holes at equal intervals along its axial direction. Each set consists of several water holes arranged at equal intervals along the circumference of the water inlet pipe. A water pusher is fixedly installed on the inner side wall of the isolation cylinder at the position corresponding to each set of water holes. The two adjacent blades of the water pusher are tilted at opposite angles.

[0014] Preferably, a number of track sleeves are fixedly installed at equal intervals along the axial direction on the outer side of the water inlet pipe. The track sleeves are provided with flower-shaped grooves. The end of the piston rod near 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 has a conical structure, and a number of spiral grooves are equally spaced along the circumference on the inner side of the conical structure of the guide sleeve.

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

[0017] Preferably, the guide groove is composed of several wedge-shaped grooves arranged at equal intervals along the circumference of the fixed sleeve, and a helical spring is provided between the striking rod and the isolation cylinder.

[0018] The beneficial effects of this invention are as follows: First, this invention uses a piston rod that moves radially back and forth along the isolation cylinder in conjunction with a guide sleeve to actively impact the cooling water inside the isolation cylinder onto the inner wall of the cooling roller, so that the cooling water directly contacts the high-temperature roller surface in the radial direction for efficient heat absorption. At the same time, the drive rod drives the vortex plate to rotate, separating and discharging the heated cooling water radially inward along the cooling roller. This breaks the traditional axial unidirectional flow mode, effectively eliminates the temperature gradient formed by the cooling water in the axial direction of the cooling roller, and ensures that the heat dissipation capacity of each section of the roller surface is uniform.

[0019] Second, the present invention uses 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 strong turbulent disturbance to the stagnant water layer near the roller wall. Combined with the multi-directional stirring effect of the water flow by the water deflector on the outside of the vortex plate, it significantly improves the convective heat transfer intensity between the cooling water and the inner wall of the cooling roller, and greatly improves the heat transfer efficiency.

[0020] Third, the present invention adopts a water-pushing fan that rotates synchronously with the isolation cylinder. Through the unique design of the opposite tilt angle of its adjacent fan blades, the cooling water flowing out of the water inlet pipe hole is rapidly diffused in both directions to the entire circumference of the inner cavity of the isolation cylinder, realizing the uniform distribution of cooling water inside the isolation cylinder. This provides a basis for the piston column to uniformly deliver cooling water to the inner wall of the cooling roller, and fundamentally and effectively ensures the consistency of the inner wall temperature of the cooling roller.

[0021] Fourth, the present invention uses a striking rod that cooperates with the guide groove on the fixed sleeve. When the isolation cylinder rotates, the striking rod is driven to periodically and radially strike the inner wall of the cooling roller. The mechanical vibration is used to peel off the scale adhering to the inner wall of the cooling roller, effectively maintaining the cleanliness of the cooling roller wall and avoiding the scale layer from reducing the heat transfer efficiency.

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

[0035] See Figure 1 and Figure 2 A cooling and shaping mechanism for producing heat insulation film includes two supports 1 arranged symmetrically on the left and right, a cooling roller 2 rotatably mounted between the two supports 1, an isolation cylinder 3 coaxially mounted 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 fixedly mounted on the left support 1. The mechanism also includes a water inlet unit 5 for forced impact water inlet and a water outlet unit 6 for active turbulent 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 that are fixedly installed on the isolation cylinder 3 at equal intervals along the axial direction. Each group consists of several guide sleeves 51 that are arranged at equal intervals along the circumference of the isolation cylinder 3. The guide sleeves 51 are arranged radially along the isolation cylinder 3. A piston column 52 is slidably provided on the inner side of the guide sleeve 51 along its axial direction. A one-way valve 53 is fixedly installed on the piston column 52 at the same axial position.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The water outlet unit 6 includes several drive rods 61 that are rotatably connected to the isolation cylinder 3 and are equally spaced along its circumference. Several spiral blades 62 are fixedly installed at equal intervals along the axial direction on the outer side of the drive rods 61, and vortex plates 63 are fixedly installed on the outer side of the spiral blades 62.

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

[0039] When the cooling roller 2 rotates, its outer wall is in continuous contact with the heat insulation film. At the same time, the piston column 52 and the guide sleeve 51 rotate with the cooling roller 2. 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, allowing the cooling water in the inner cavity of the isolation cylinder 3 to flow 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, causing the piston column 52 to push the cooling water in the guide sleeve 51 to impact the inner roller wall of the cooling roller 2 radially. This allows the heat on the heat insulation film to be quickly conducted through the roller wall of the cooling roller 2 to the cooling water at the inner roller wall of the cooling roller 2, causing the cooling water at the inner roller wall of the cooling roller 2 to heat up.

[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 blade 62 on it rotate synchronously, so that the rotating vortex plate 63 radially entrains the cooling water heated at the inner roller wall of the cooling roller 2. Then the heated cooling water is actively discharged away from the inner roller wall of the cooling roller 2 through the rotating spiral blade 62.

[0041] By actively inleting and draining water, the axial flow of cooling water on the inner wall of the cooling roller 2 is effectively reduced, ensuring the temperature consistency of each section on the cooling roller 2, thereby improving the cooling effect on the heat insulation film. Furthermore, the active inlet and outlet water flow efficiently improves the fluidity of the cooling water, prevents the cooling water from stagnating, and ensures that the temperature change of the cooling roller 2 wall is small.

[0042] To quickly expand the cooling water flowing from the 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 column 52 is consistent, the present invention makes the following design: (See reference) Figure 2 , Figure 3 , Figure 4 , Figure 9 and Figure 10 The water inlet pipe 4 is provided with several sets of water holes at equal intervals along its axial direction. Each set consists of several water holes arranged at equal intervals along the circumference of the water inlet pipe 4. A water pusher 54 is fixedly installed on the inner wall of the isolation cylinder 3 at the position corresponding to each set of water holes. The two adjacent blades of the water pusher 54 have opposite deflection angles.

[0043] When the cooling water inside the inlet pipe 4 is discharged from the water hole on it, the isolation cylinder 3 drives the water pusher 54 on it to rotate synchronously. The water pusher 54 pushes the cooling water bidirectionally along the axis of the isolation cylinder 3 through its blades with opposite deflection angles. This allows the cooling water to quickly spread 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. This ensures that the temperature of the cooling water delivered by each piston column 52 is consistent, thus guaranteeing the uniformity of the temperature of the cooling roller 2 wall.

[0044] See Figure 2 , Figure 4 and Figure 7 Several track sleeves 55 are fixedly installed at equal intervals along the axial direction on the outer side of the water inlet pipe 4. The track sleeves 55 are provided with flower-shaped grooves. The end of the piston column 52 near the axis of the cooling roller 2 is slidably connected to the flower-shaped groove through a T-shaped rod 551.

[0045] When the isolation cylinder 3 starts to rotate, the isolation cylinder 3 drives the piston rod 52 to move synchronously through the guide sleeve 51. The piston rod 52 drives the T-shaped rod 551 to move along the flower groove of the track sleeve 55, so that the T-shaped rod 551 drives the piston rod 52 to reciprocate radially along the isolation cylinder 3.

[0046] To prevent scale buildup from the cooling water from adhering to the inner wall of the cooling roller 2, which would thicken the roller wall and reduce heat transfer efficiency, the present invention incorporates the following design: (See attached diagram) Figure 2 , Figure 3 , Figure 4 and Figure 8Several fixed sleeves 56 are fixedly installed at equal intervals along the axial direction on the outer side of the water inlet pipe 4. Guide grooves are provided on the fixed sleeves 56. Several striking rods 561 corresponding to the guide sleeves 51 are slidably arranged on the isolation cylinder 3 along its radial direction. The part of the striking rod 561 near the axis of the cooling roller 2 is slidably connected in the guide groove. The guide groove is composed of several wedge-shaped grooves arranged at equal intervals along the circumference of the fixed sleeves 56. A helical spring is provided between the striking rod 561 and the isolation cylinder 3.

[0047] When the isolation cylinder 3 starts to rotate, it drives the striking rod 561 to move synchronously, causing the striking rod 561 to move along the trajectory of the guide groove. When the end of the striking rod 561 near the axis of the isolation cylinder 3 contacts the wedge-shaped surface of the wedge groove, the striking rod 561 moves along the wedge-shaped surface of the wedge groove towards the axis of the isolation cylinder 3 and compresses the helical spring. When the striking rod 561 moves to a section of the wedge groove arranged radially along the isolation cylinder 3, the helical spring pushes the striking rod 561 away from the axis of the isolation cylinder 3 through its own elasticity, so that the striking rod 561 periodically strikes the inner wall of the cooling roller 2 radially, using mechanical vibration to peel off the scale adhering to the inner wall of the cooling roller 2, effectively maintaining the cleanliness of the roller wall of the cooling roller 2 and avoiding the scale layer from reducing the heat transfer efficiency.

[0048] To enable the piston rod 52 to push the cooling water inside the guide sleeve 51 to quickly contact the inner roller wall of the cooling roller 2, thus ensuring efficient cooling of the cooling roller 2, and to 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: (See reference) Figure 4 and Figure 7 The portion of the guide sleeve 51 away from the axis of the cooling roller 2 has a conical structure, and several spiral grooves are equally spaced along the circumference on the inner side of the conical structure of the guide sleeve 51.

[0049] When the piston rod 52 pushes the cooling water inside the guide sleeve 51 outward, the cooling water moves to the conical structure of the guide sleeve 51. As the diameter of the guide sleeve 51 decreases, the water flow speed increases, allowing the cooling water inside the guide sleeve 51 to quickly impact the inner roller wall of the cooling roller 2. This maximizes the use of low-temperature cooling water to cool the heat 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, causing the cooling water to rotate and flow 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 drive rod 61, and a fixed toothed ring 612 that meshes with all the transmission gears 611 is fixedly installed on the support 1 on the left.

[0051] See Figure 5Several water-dispensing plates 631 are fixedly installed at equal intervals along the circumference of the corresponding drive rod 61 on the outer side of the vortex plate 63, and the spiral blades 62 have a symmetrical structure 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, which is arranged in a one-to-one correspondence with the drive 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 pipes 641 are rotatably connected and connected to 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 through holes in the middle. The vortex plate 63 is rotatably connected and communicated with the corresponding three-way pipe 641 through the through holes on its plate-shaped structure. The left side of the leftmost three-way pipe 641 and the right side of the rightmost three-way pipe 641 are both closed by abutting against the isolation cylinder 3.

[0054] When the cooling roller 2 and the isolation cylinder 3 start to rotate, the isolation cylinder 3 drives the drive rod 61 on it to rotate synchronously, so that the drive rod 61 drives the transmission gear 611 to rotate circumferentially along the fixed gear ring 612, so that the transmission gear 611 rotates by meshing with the fixed gear ring 612, and then the drive rod 61 drives the corresponding spiral blade 62 and vortex plate 63 to rotate. The vortex plate 63 rolls the heated cooling water along the radial direction of the cooling roller 2 to its center position, and then the spiral blade 62 pushes it to both ends of the vortex plate 63, so that the cooling water actively flows through the three-way pipe 641 into the water outlet pipe 64, thereby realizing the active discharge of heated cooling water from the water outlet pipe 64.

[0055] By using the above-mentioned active radial drainage method, the cooling water after heating is prevented from remaining on the inner wall of the cooling roller 2, which would affect the heat conduction of the cooling roller 2 to the heat insulation film. When the vortex plate 63 rotates, it drives the water-dispelling plate 631 on its outer side to further agitate the water flow, significantly improving the convective heat transfer 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 flow guide sleeve 51, piston column 52, vortex plate 63 and other structures in this invention are all made from basic industrial components. The flow guide sleeve 51, vortex plate 63 and other components are made using conventional casting or sheet metal processes (such as stainless steel milling, aluminum bending). The moving parts such as piston column 52, T-shaped rod 551 and other components are medium carbon steel machined parts. The tee pipe 641 is based on the modification of standard pipe fittings. All parts are processed using general-purpose machine tools (such as milling machines, wire cutting machines), with no precision tolerance requirements. The whole machine is achieved through modular assembly, which greatly reduces the assembly complexity.

[0057] Furthermore, the cost of the new components is extremely low, far lower than the waste film loss caused by uneven cooling. The entire machine is designed with mechanical transmission, eliminating the need for an additional power source and avoiding excessive energy consumption. At the same time, the improved cooling uniformity and reduced scaling rate brought about by this invention make the overall benefits far exceed the cost of structural increments, fully meeting the practical requirements for industrial mass production and long-term use.
