Description

Technical Field

[0001] This utility model belongs to the technical field of release film production equipment, specifically a high-speed dispersion device for release film production. Background Technology

[0002] High-speed dispersers play a crucial role in the production of release films, ensuring precise dispersion and functional synergy. Their function permeates core processes such as release agent formulation, coating liquid homogenization, and functional enhancement, directly affecting key performance indicators of release films, including peel stability, surface smoothness, and durability.

[0003] Traditional dispersers generally employ a single-shaft, single-layer stirring structure. This mechanical design, originating from the mid-20th century, has shown significant limitations when dealing with modern high-solids-content, high-viscosity material systems. Its core shortcomings are threefold: First, the single-axial laminar shear mode makes it difficult to construct an effective three-dimensional turbulent field, resulting in significant concentration gradients in both the radial and axial directions. Second, the linear shear rate of conventional impellers cannot adapt to the dynamic changes in the rheological properties of materials, especially in the processing of non-Newtonian fluids, easily leading to "shear dead zones." Third, the lack of an intelligent process control system makes it difficult to achieve precise control of key parameters such as dispersion and particle size distribution. Utility Model Content

[0004] Therefore, it is necessary to provide a high-speed dispersion device for release film production, which adopts a dual-shaft stirring design to fully stir and disperse the materials, and is more intelligent, allowing for more precise control of the material dispersion to ensure uniform material dispersion.

[0008] Optionally, in one embodiment of the present invention, the second stirring paddle includes a second rotating shaft and at least one serrated dispersion disk, wherein a plurality of the serrated dispersion disks are arranged vertically on the second rotating shaft.

[0009] Optionally, in one embodiment of the present invention, the walking mechanism is provided with an annular rack and a connecting arm. The upper end of the connecting arm is provided with a walking motor, the output end of the walking motor meshes with the annular rack, the lower end of the connecting arm is screwed to a second rotating shaft, and the connecting arm is also screwed to a first rotating shaft.

[0026] Example 1

[0027] To address the shortcomings of existing dispersers in achieving satisfactory material dispersion and precisely controlling material dispersion, a more intelligent and efficient high-speed dispersion device was designed. The specific solution is as follows:

[0028] like Figure 1-5 As shown, a high-speed dispersion device for release film production includes: a frame 1 and a stirring mechanism disposed on the upper part of the frame 1. The frame 1 is provided with a lifting mechanism. A stirring tank 2 is disposed below the stirring mechanism. The stirring mechanism is provided with two stirring blades driven by a motor. The stirring blades include a first stirring blade and a second stirring blade with different blade structures for different dispersion functions. The first stirring blade and the second stirring blade are connected by a transmission. The stirring mechanism is also provided with a lifting device, and the stirring mechanism also includes a tank cover 3 for covering the stirring tank 2 to prevent material from splashing outward. The tank cover 3 is provided with a traveling mechanism that can control the position of the second stirring blade.

[0029] like Figure 2 As shown, an industrial controller 105 is also provided on one side of the frame 1. The industrial controller 105 can be a common industrial computer, which can set and control the parameters of the whole machine. The industrial controller 105 is electrically connected to the moving parts of the device.

[0030] like Figure 1-2 As shown, multiple fixing rods 104 are connected around the barrel lid 3. The upper end of the fixing rods 104 is fixedly connected to the frame 1 to ensure that the barrel lid 3 is stable. The barrel lid 3 is also provided with a feed inlet 302. The bottom of the mixing barrel 2 is provided with a discharge outlet 201. In other schemes, multiple feed inlets 302 can be provided for the feeding of different materials or a multi-port connector can be provided.

[0031] like Figure 1 As shown, the first stirring paddle includes a first rotating shaft 4, a frame-type blade 403 and a cylindrical dispersion disk 404. The cylindrical dispersion disk 404 is located at the lower end of the first stirring paddle, and the connection between the lower end of the frame-type blade 403 and the first rotating shaft 4 is located at the bottom of the dispersion disk.

[0032] like Figure 1 , 4 As shown in Figure 5, a drive motor 401 is connected to the upper end of the first rotating shaft 4. The drive motor 401 is a variable frequency motor. A reducer is connected between the output end of the drive motor 401 and the first rotating shaft 4. Both the reducer and the drive motor 401 are located inside the frame 1 to maintain the overall aesthetics. The top of the frame 1 is provided with an openable cover plate for easy access to inspect and replace the drive motor 401. The frame-type paddle 403 includes an "L"-shaped structure on the periphery and an "U"-shaped structure near the center. The cylindrical dispersing disk 404 abuts against the lower end of the frame-type paddle 403. The cylindrical dispersing disk 404 has several annular dispersing teeth from the outside to the inside. The size of the dispersing teeth is arranged from large to small from the outside to the inside. The part of the frame-type paddle 403 located below the cylindrical dispersing disk 404 has a spiral blade structure and the pushing direction is upward. It can push the nearby material into the cylindrical dispersing disk 404, and then disperse it through the cylindrical dispersing disk 404 before flowing outwards, thus improving the dispersion effect.

[0033] like Figure 1 As shown, the second stirring paddle includes a second rotating shaft 5 and at least one serrated dispersion disk 502. Multiple serrated dispersion disks 502 are arranged vertically on the second rotating shaft 5. In this embodiment, the second stirring paddle is provided with three serrated dispersion disks 502. The edges of the serrated dispersion disks 502 are provided with several "V"-shaped dispersion teeth. The serrations of the three serrated dispersion disks 502 are different in size, arranged from top to bottom in ascending order. The larger serrated disk has a larger diameter, higher linear velocity, and stronger shearing force, which can apply higher intensity dispersion to the pre-treated material and reduce the bottom stirring dead zone. The second stirring paddle is located between the frame blade 403 and the first rotating shaft 4. Even if the second stirring paddle does not move, it will not interfere with the rotation of the first stirring paddle.

[0034] like Figure 1 , 2As shown, the traveling mechanism includes a ring rack 602 and a connecting arm. A traveling motor 601 is located at the upper end of the connecting arm. The output end of the traveling motor 601 is connected to a traveling gear, which meshes with the ring rack 602. Rotation of the traveling motor 601 causes the connecting arm to rotate, thereby driving the second stirring paddle to rotate and displace. High-speed rotation is maintained during this displacement. The lower end of the connecting arm is screwed onto the second rotating shaft 5, and the connecting arm is also screwed onto the first rotating shaft 4. The connecting arm has a horizontally placed "U"-shaped structure. The middle part of the connecting arm is screwed onto the first rotating shaft 4, where a transmission gear 402 is located. The top of the second rotating shaft 5 is equipped with... There is a driven gear 501, and the transmission gear 402 is connected to the driven gear 501 by a transmission belt. In other solutions, a second drive motor 401 is installed on the bucket lid 3. The transmission gear 402 is an independent component. The speed or direction of rotation of the second rotating shaft 5 can be controlled by the second drive motor 401, so that the first rotating shaft 4 and the second rotating shaft 5 have completely different speeds or directions, providing reverse shearing force. In other solutions, the travel motor 601 is fixedly installed on the bucket lid 3, and the annular rack 602 is connected to the connecting arm. When the travel motor 601 is running, the entire annular rack 602 rotates and drives the connecting arm to rotate and move.

[0035] As shown in 1-2 and 4, the bottom of the frame 1 has a "U"-shaped structure, and a rotatable locking block 103 is provided on the inner side. The locking block 103 has a U-shaped limiting groove 1031. Correspondingly, the lower part of the mixing tank 2 has an outwardly protruding limiting block 202. The locking block 103 is connected to a telescopic rod or a small motor to control the rotation of the entire locking block 103. When the limiting block 202 is located behind the limiting groove 1031, the locking block 103 rotates so that the opening of the limiting groove 1031 faces upward, that is, the locking block 103 rotates 90° clockwise, which serves to limit the mixing tank 2.

[0036] like Figure 1-2 As shown, the bucket lid 3 is also equipped with an observation window 301 and a light, which makes it easy to observe the material dispersion through the observation window 301. The light is a ring-shaped light strip located inside the bucket lid 3. When observation is needed, the light can be turned on. The observation window 301 is a circular window with the center of the window facing the lower end of the main stirring shaft.

[0037] like Figure 1-2 As shown, the lifting mechanism is located on the column part of the frame 1. The lifting mechanism includes a hydraulic lifting rod 101 and guide rods 102 on both sides of the lifting rod 101.

[0038] like Figure 1 , 3 As shown, the annular rack 602 is provided with an annular cover plate on the outside. The annular cover plate is installed on the top of the barrel lid 3. The annular cover plate is provided to prevent dust from accumulating at the position of the annular rack 602.

[0039] like Figure 1 As shown, the lower end of the connecting arm is also connected to an installation rod 604. The lower end of the installation rod 604 is equipped with a viscosity sensor 603 to monitor the material dispersion in real time. The installation rod 604 can place the viscosity sensor 603 in the material to play a monitoring role. The viscosity sensor 603 can be displaced with the rotation of the connecting arm and can monitor the material dispersion at various positions.

[0040] Working principle:

[0041] When using the equipment, first place the mixing tank 2 into the frame 1 and limit the mixing tank 2 with the locking block 103. Then, control the tank lid 3 to fall down and cover the mixing tank 2. Then, feed the material into the tank through the feed port 302. After the material is fed in, start the mixing mechanism. The mixing mechanism starts to mix and disperse at a slow speed. After the initial dispersion, the speed is gradually increased to disperse the material at high speed. During dispersion, the traveling mechanism controls the second mixing paddle to revolve slowly. At the same time, the viscosity sensor 603 detects the material. When it detects that the material in a certain part is not dispersed enough, the traveling mechanism stops operating, and the second mixing paddle strengthens the dispersion at the current position. After completion, it resumes the revolve movement. This process is repeated until the material is dispersed to the preset dispersion degree, at which point the operation stops. During the dispersion process, the drive motor 401 can automatically change the frequency according to the signal of the viscosity sensor 603 to control the speed of the two mixing paddles. The tank lid 3 can be opened by the operator, or the entire process can be automated.

[0042] The high-speed dispersion device of this scheme adopts a dual-shaft structure design. In addition to the first stirring paddle in the center, there is a second stirring paddle that revolves around the first stirring paddle. The barrel cover 3 is equipped with a traveling mechanism, which can control the second rotating shaft 5 to move along the rotation trajectory to the required position. When the viscosity sensor 603 detects that the material dispersion in a certain part is insufficient, the second stirring paddle can be moved to that point to strengthen the shearing, which can ensure the uniformity of material dispersion. The two stirring paddles are controlled by the same drive source, reducing the number of drive sources required. The structure of the mixing barrel 2 cooperates with the limiting block 202 at the bottom of the frame 1 to limit the horizontal direction of the mixing barrel 2, ensuring stable dispersion.

[0043] Example 2

[0044] In this embodiment, the structure of the high-speed dispersion device is basically the same as that of Embodiment 1. The difference is that a scraper is also connected to the frame-type paddle 403 located on one side. The scraper abuts against the inner wall of the mixing tank 2 to scrape off the material remaining on the inner wall surface of the mixing tank 2.
