Description

Technical Field

[0001] This utility model relates to the field of shear dispersion technology, specifically to a shear dispersion machine for premixing toughening agent and epoxy resin. Background Technology

[0002] Epoxy resin, as one of the most widely used thermosetting materials, possesses excellent mechanical strength, chemical stability, and electrical insulation due to its highly cross-linked three-dimensional network structure, and is widely used in composite materials, structural adhesives, and protective coatings.

[0003] The existing patent, CN120718278A, entitled "An Epoxy Resin Toughening Agent and Its Preparation Method and Application," describes a silicon-containing block copolymer toughening agent that needs to form a nanoscale dispersed phase and a microphase separation structure in the epoxy resin matrix to significantly improve toughness. Although this patent is innovative in the design of the toughening agent's molecular structure, it only uses conventional mechanical stirring methods to achieve its ideal nanoscale dispersion through mechanical dispersion equipment, lacking a targeted and efficient dispersion device.

[0004] The existing patent, CN120484239A, entitled "Toughening Agent, Toughened Epoxy Resin Adhesive, Preparation Method and Application Thereof," develops a highly efficient toughening agent based on bio-based molecules, emphasizing that the toughening agent can effectively improve the impact strength and bond strength of epoxy resin adhesives even at low addition levels. However, this patent also fails to solve the process problem of easy agglomeration and uneven dispersion of the toughening agent in high-viscosity epoxy resin matrices. The traditional stirring equipment it relies on cannot provide sufficient and precise shear force, resulting in the toughening agent not being able to fully exert its toughening efficiency.

[0005] Existing shear dispersers are mostly single-function and have the following main drawbacks: First, the stirring components can usually only rotate along a fixed trajectory, lacking the ability to circulate and adjust vertically within the mixing container. This results in mixing dead zones at different heights of the material, preventing the toughening agent and resin from achieving uniform mixing throughout the entire process. Second, the traditional dispersion disc structure is fixed and cannot adjust the shear intensity and flow field morphology in real time according to changes in material viscosity or the dispersion process. This makes them particularly unsuitable for handling conditions requiring multi-stage shearing (such as first breaking up agglomerated particles and then finely dispersing them). Utility Model Content

[0011] In a preferred embodiment of this utility model, the connecting shearing assembly consists of a rotary motor and several long rods. The long rods are evenly distributed circumferentially and fixedly connected to the bottom of the fixed disc. The long rods are connected to the shearing dispersion disc. The rotary motor is installed at the bottom of the fixed disc, and a shearing shaft is installed at the output end of the rotary motor. A connecting frame is fixedly connected to the bottom of the shearing shaft. By driving the shearing shaft and the connecting frame to rotate at high speed through the rotary motor, the basic shearing action on the material is realized.

[0012] In a preferred embodiment of this utility model, a bearing is provided on the outer circumferential surface of the shearing shaft, and the shearing dispersion disk is movably sleeved on the outer circumferential surface of the bearing. The relative rotation of the shearing dispersion disk is realized through the bearing connection, generating an additional shearing layer and further improving the dispersion efficiency.

A telescopic rod is movably hinged between the shearing blades and the sliding disks on the same side.

[0014] In a preferred embodiment of this utility model, the outer arc guide frame and the inner arc guide frame have the same curvature, the outer arc guide frame and the inner arc guide frame are arranged in a cross configuration, and a gap is provided between the inner arc guide frame and the outer arc guide frame. Through the cross-arranged flow guide frames, a high shear region is formed at the gap, generating a strong turbulence effect, which is beneficial to the breaking of clumps.

[0015] As a preferred embodiment of this utility model, a number of evenly distributed circular shafts are fixedly connected inside the outer arc guide frame. The limiting shafts pass through the interior of the two sliding discs. Through the guiding effect of the limiting shafts, the movement accuracy of the sliding discs is ensured, and the stability and reliability of the entire adjustment mechanism are improved.

[0016] The working principle and beneficial effects of this utility model are as follows: 1. This utility model, through the setting of a circulating telescopic component and an eccentric meshing gear, etc., the circulating telescopic component is driven by a servo motor to drive the eccentric meshing gear, which transforms the uniform rotation into variable speed reciprocating motion, so that the shearing and dispersing disc makes variable speed reciprocating motion in the vertical direction, effectively breaking the stable flow field formed by the material during the mixing process, and significantly improving the overall mixing efficiency of the material.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Example like Figures 1-10 As shown, a shear dispersion machine for premixing toughening agent and epoxy resin includes a main body 100, which is composed of a placement base 101 and a support frame 103 fixedly connected to each other. An external controller 102 is installed on one side of the main body 100. The external controller 102 is used for power supply and control connection of the equipment. A circulating telescopic component 200 for repeatedly adjusting the material shearing and dispersion height is installed on one side of the main body 100. The bottom of the circulating telescopic assembly 200 is equipped with a shearing and dispersing assembly 300 for material shearing and dispersing. The shearing and dispersing assembly 300 consists of a shearing assembly 310 and a shearing and dispersing disk 320. The shearing assembly and the shearing and dispersing disk 320 are connected sequentially along the axis of the circulating telescopic assembly 200. The shearing assembly is used for the rotational shearing and dispersing of materials, and the shearing and dispersing disk 320 is used to assist in the shearing and dispersing of materials.

[0023] A shear dispersion machine for premixing toughening agent and epoxy resin has a main body 100 consisting of a base 101 and a support frame 103 connected by welding to form a stable frame. An external controller 102 is installed on one side of the main body 100. The external controller 102 contains a power module and control circuitry, and is connected to the various electrical components of the equipment via cables to supply power and set operating parameters. A circulating telescopic assembly 200 is installed on one side of the main body 100. The driving force of the circulating telescopic assembly 200 causes the shearing components to circulate reciprocally in the vertical direction during material mixing, thereby expanding the mixing range. A shear dispersion assembly 300 is installed at the bottom of the circulating telescopic assembly 200. The shear dispersion assembly 300 is composed of a connecting shearing assembly 310 and a shear dispersion disc 320 connected sequentially from top to bottom along the axis. The connecting shearing assembly 310 is driven by a motor to generate high-speed rotation, performing preliminary mechanical shearing on the toughening agent and epoxy resin mixture. The shear dispersion disc 320 below generates strong turbulence and shearing force during rotation, further refining the material particles and achieving thorough dispersion and mixing of the material.

[0024] An electric cylinder 104 is mounted on the top of the support frame 103. A telescopic shaft 105 is mounted on the output end of the electric cylinder 104. The electric cylinder 104 is used for height adjustment of the cyclic telescopic assembly 200 and the shearing dispersion assembly 300.

[0025] An electric cylinder 104 is installed at the top center of the support frame 103. When the external controller 102 issues a command, the electric cylinder 104 drives the telescopic shaft 105 to perform vertical telescopic movement. The bottom of the telescopic shaft 105 is fixedly connected to the guide frame 201 of the circulating telescopic assembly 200, thereby driving the entire circulating telescopic assembly 200 and its bottom shearing and dispersing assembly 300 to adjust their position in the vertical direction, so that the equipment can adapt to mixing containers of different depths.

[0026] The recirculating telescopic assembly 200 is composed of a guide frame 201, which is fixedly connected to the bottom of the telescopic shaft 105; A fixed guide frame 202 is fixedly connected inside the guide frame 201. A servo motor 203 is installed on one side of the fixed guide frame 202. A rotating shaft 204 is installed at the output end of the servo motor 203. A first meshing gear 205 is fixedly sleeved on the outer circumferential surface of the rotating shaft 204. A sliding frame 206 is slidably assembled inside the guide frame 201. A connecting rod 207 is fixedly connected to one end of the sliding frame 206. The connecting rod 207 is slidably assembled inside the guide frame 201. A fixed disc 210 is fixedly connected to the bottom of the connecting rod 207. A rotating shaft 208 is rotatably installed inside the sliding frame 206. A second meshing gear 209 is fixedly sleeved on the outer circumferential surface of the rotating shaft 208.

[0027] The revolving telescopic assembly 200 includes a cubic guide frame 201, which is fixedly connected to the bottom of the telescopic shaft 105 via a flange. A fixed guide frame 202 is fixedly installed inside the guide frame 201. A servo motor 203 is installed on one side of the fixed guide frame 202. The output end of the servo motor is connected to a rotating shaft 204 via a coupling. A first meshing gear 205 is fixedly fitted on the rotating shaft 204. A sliding frame 206 is also slidably assembled inside the guide frame 201, with one side of the sliding frame 206 extending... A connecting rod 207 is provided, which passes through a guide hole in the side wall of the guide frame 201 and can slide freely therein. The bottom of the connecting rod 207 is connected to a fixed disc 210. A rotating shaft 208 is rotatably mounted inside the sliding frame 206 via a bearing seat. A second meshing gear 209 is fixedly fitted on the rotating shaft 208. When the servo motor 203 drives the first meshing gear 205 to rotate, it drives the sliding frame 206 to reciprocate linearly within the guide frame 201 through meshing transmission with the second meshing gear 209.

[0028] The connection point between the first meshing gear 205 and the rotating shaft 204 is located on one side of the first meshing gear 205, and the connection point between the second meshing gear 209 and the rotating shaft 208 is located on one side of the second meshing gear 209.

[0029] The connection point between the first meshing gear 205 and the rotating shaft 204 is located at the radial eccentric position of the gear. Similarly, the connection point between the second meshing gear 209 and the rotating shaft 208 is also located at the radial eccentric position of the gear. The eccentric setting causes the first meshing gear 205 and the second meshing gear 209 to generate non-uniform speed ratio motion characteristics during meshing transmission. When the servo motor 203 rotates at a constant speed, the uniform input can be converted into an output with periodically changing speed through the transmission of this pair of eccentric gears, thereby driving the sliding frame 206 to generate a reciprocating linear motion with variable speed. This motion characteristic helps to break the stable flow field formed by the material during the mixing process, generate a more complex flow pattern, and enhance the mixing effect.

[0030] The connecting shearing assembly 310 consists of a rotary motor 312 and several long rods 311. The several long rods 311 are evenly distributed in a circle and fixedly connected to the bottom of the fixed disk 210. The long rods 311 are connected to the shearing dispersion disk 320. The rotary motor 312 is installed at the bottom of the fixed disk 210. The output end of the rotary motor 312 is equipped with a shearing shaft 313. The bottom of the shearing shaft 313 is fixedly connected to a connecting frame 315.

[0031] The specific structure of the connecting shearing assembly 310 includes several long rods 311 welded evenly around the bottom of the fixed disc 210. The long rods 311 extend downward and are fixedly connected to the shearing dispersion disc 320. A rotary motor 312 is installed at the center of the bottom of the fixed disc 210. The output end of the rotary motor 312 drives the shearing shaft 313 to rotate at high speed via a key connection. The bottom of the shearing shaft 313 is connected to a connecting frame 315 via a flange. When the rotary motor 312 starts, it drives the shearing shaft 313 and the connecting frame 315 to rotate together. Due to the fixed connection between the long rods 311 and the shearing dispersion disc 320, the entire shearing dispersion disc 320 also rotates, realizing the basic shearing effect on the material.

[0032] A bearing 314 is provided on the outer circumferential surface of the shearing shaft 313, and the shearing dispersion disk 320 is movably sleeved on the outer circumferential surface of the bearing 314.

[0033] A bearing 314 is installed on the outer circumferential surface of the shearing shaft 313. The bearing 314 adopts a deep groove ball bearing structure, which consists of an inner ring, an outer ring, rolling elements, and a cage. The shearing dispersion disc 320 is movably sleeved on the outer ring of the bearing 314 through its central hole, so that the shearing dispersion disc 320 can rotate freely relative to the shearing shaft 313. The rotary motor 312 drives the shearing shaft 313 and the connecting frame 315 to rotate at high speed to perform the main shearing operation.

[0034] The shearing dispersion disk 320 is composed of an impact frame 321, which is fixedly connected to the bottom of several long rods 311. Two inner arc guide frames 322 are fixedly connected to the inner wall of the impact frame 321 along the axial axis of the impact frame 321. An outer arc guide frame 323 is rotatably installed inside the impact frame 321. The outer arc guide frame 323 is fixedly connected to the connecting frame 315. An adjusting motor 324 is installed on the top of the outer arc guide frame 323. A connecting shaft 325 is installed at the output end of the adjusting motor 324. A two-way lead screw 326 is fixedly connected to one end of the connecting shaft 325. Two symmetrically arranged sliding discs 327 are slidably assembled inside the outer arc guide frame 323. Several circumferentially distributed shearing blades 329 are movably hinged on both the upper and lower sides of the outer arc guide frame 323. A telescopic rod 330 is movably hinged between the shearing blades 329 and the sliding discs 327 on the same side.

[0035] The shearing dispersion disc 320 includes an annular impact frame 321, which is fixedly connected to the bottom of a long rod 311 by bolts. The wall of the impact frame 321 has densely distributed mesh-like holes, forming a continuous hollow structure on the surface. Two inner arc guide frames 322, symmetrically arranged along the axis, are fixedly connected to the inner wall of the impact frame 321. These inner arc guide frames are shaped like arc-shaped guide plates. An outer arc guide frame 323 is rotatably installed inside the impact frame 321 and is fixedly connected to a connecting frame 315. An adjusting motor 324 is installed on the top of the outer arc guide frame 323. The output end of the adjusting motor 324 is connected to a connecting shaft 325 via a coupling. A bidirectional lead screw 326 is fixed to the end of the connecting shaft 325. Two symmetrically arranged sliding discs 327 are slidably assembled inside the outer arc guide frame 323. The two sliding discs 327 are respectively engaged with the upper and lower threaded sections of the bidirectional lead screw 326 through their internal nuts. Several circumferentially distributed shearing blades 329 are movably hinged on both sides. The shearing blades 329 are movably hinged to the sliding discs 327 via telescopic rods 330. When the equipment is working, the material undergoes preliminary screening and shearing when passing through the mesh holes of the impact frame 321. Larger particles are blocked and continue to be sheared, while the material that meets the requirements passes through the holes to enter the next stage. At the same time, the regulating motor 324 drives the bidirectional lead screw 326 to rotate, causing the two sliding discs 327 to move towards or away from each other. The telescopic rods 330 push the shearing blades 329 to change their inclination angle, thereby realizing secondary shearing adjustment of the material passing through the mesh holes. The mesh holes not only enhance the material's passability but also create an additional shearing interface, improving dispersion efficiency. The outer arc guide frame 323 and the inner arc guide frame 322 have the same curvature and are arranged in a cross pattern. There is a gap between the inner arc guide frame 322 and the outer arc guide frame 323.

[0036] The outer arc guide frame 323 and the inner arc guide frame 322 have the same radius of curvature and arc angle to ensure the consistency of the flow field. The outer arc guide frame 323 and the inner arc guide frame 322 are arranged in a cross pattern in space. The installation positions of the outer arc guide frame 323 and the inner arc guide frame 322 are offset by a certain angle in the circumferential direction. An appropriate gap is maintained between the inner arc guide frame 322 and the outer arc guide frame 323. The gap forms a channel for material flow. When the equipment is working, the fixed inner arc guide frame 322 and the rotating outer arc guide frame 323 generate relative motion, forming a high shear area at the gap. The cross arrangement makes the material subject to the constantly changing flow channel shape when passing through, generating strong turbulence and shearing effects, which is beneficial to the breaking and uniform dispersion of clumps.

[0037] The outer arc guide frame 323 has several evenly distributed circular shafts 328 fixedly connected inside, and the shafts 328 pass through the interior of the two sliding discs 327.

[0038] Several circumferentially distributed limiting shafts 328 are fixedly connected inside the outer arc guide frame 323. The limiting shafts 328 are arranged parallel to the axis of the bidirectional lead screw 326. Two sliding discs 327 have guide holes that match the limiting shafts 328, allowing the limiting shafts 328 to pass through the interior of the two discs. When the adjusting motor 324 drives the bidirectional lead screw 326 to rotate, the sliding discs 327 can only move linearly under the constraint of the limiting shafts 328 and cannot rotate with the lead screw. This ensures the motion accuracy of the sliding discs 327 and prevents them from deflecting during the movement. This ensures that all shear blades 329 can adjust their angle synchronously and smoothly, maintaining dynamic balance. The evenly distributed arrangement of the limiting shafts 328 provides stable multi-point support for the sliding discs 327, improving the rigidity and reliability of the entire adjusting mechanism.

[0039] Working principle: First, the device is started via the external controller 102. The electric cylinder 104 drives the telescopic shaft 105 to extend and retract vertically, causing the circulating telescopic component 200 and its bottom shearing and dispersing component 300 to rise and fall to the predetermined working height. Then, the servo motor 203 starts, driving the eccentrically set first meshing gear 205 to rotate via the rotating shaft 204. This gear meshes with the similarly eccentrically set second meshing gear 209, converting the uniform rotation into variable speed reciprocating motion, driving the sliding frame 206 to reciprocate along the guide frame 201. At the same time, the rotary motor 312 starts, driving the connecting frame 315 to rotate via the shearing shaft 313, while the long rod 311... The impact frame 321, which is fixedly connected to the shearing and dispersing disc 320, also rotates. During this process, the adjusting motor 324 drives the bidirectional lead screw 326 to rotate through the connecting shaft 325, causing the two sliding discs 327 to move towards or away from each other under the guidance of the limiting shaft 328. The shearing blades 329 are adjusted by the telescopic rod 330. When the equipment is working, the material is first sheared by the connecting frame 315, then preliminarily screened through the mesh holes of the impact frame 321, then sheared in the gap formed by the cross-arranged inner arc guide frame 322 and outer arc guide frame 323, and finally dispersed by the angle-adjustable shearing blades 329, thus achieving efficient and uniform mixing of toughening agent and epoxy resin.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
