Description

Technical Field

[0001] The utility model belongs to the technical field of ink material production, and particularly relates to a microcapsule preparation device for ink material production. Background Art

[0002] In the preparation of microcapsules for ink, the purpose of adding the oil phase to the water phase for emulsification is to evenly disperse the ink raw materials in water to form a stable emulsion, thereby facilitating the subsequent microencapsulation process.

[0003] In the preparation of microcapsules for inks, the water phase and the oil phase are often directly mixed. Direct mixing may cause the oil phase to quickly aggregate to form larger oil droplets, which is not conducive to forming a uniform and stable emulsion, affecting the final quality of the microcapsules. It may not be possible to well control the uniform distribution of the wall material, making it impossible for the wall material to effectively cover the oil droplets and form a uniform microcapsule structure.

[0004] Therefore, in order to ensure the quality and performance of microcapsules and form a uniform and stable emulsion in the preparation of microcapsules for ink, we propose a microcapsule preparation device for ink material production. Utility Model Content

[0005] The present invention aims to solve the technical problem that in the prior art, the water phase and the oil phase are directly mixed without an appropriate emulsification step, and the oil phase quickly aggregates to form larger oil droplets, which is not conducive to forming a uniform and stable emulsion.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A microcapsule preparation device for ink material production includes an emulsification tank and a constant-flow dripping mechanism. The tank cover on the top of the emulsification tank is provided with an opening for inserting an oil phase dripping tube into the emulsification tank. The constant-flow dripping mechanism is used to push the oil phase into the oil phase dripping tube and slowly drip the oil phase toward the water phase in the emulsification tank through the oil phase dripping tube.

[0008] The constant flow dripping mechanism includes two sleeves for containing the oil phase, a piston rod used in conjunction with the sleeve to draw the oil phase into or out of the sleeve, and two lead screw linear modules that drive the piston rod to reciprocate in the sleeve to push the oil phase in the sleeve out or draw the oil phase into the sleeve.

[0009] The two screw linear modules drive the piston rod to rise or fall steadily, thereby drawing the oil phase into or out of the casing. After the oil phase is pushed out of the casing, it is slowly dripped into the water phase in the tank through the oil phase dripping tube at a constant flow rate.

[0010] Preferably, a steel frame is fixed to the tank lid, and an agitator is fixed to the steel frame and extends into the emulsification tank. The steel frame provides additional structural stability, and the presence of the agitator can effectively mix the oil phase and the water phase, promoting the emulsification process, thereby improving the quality and efficiency of the microcapsules.

[0011] As a preferred embodiment, the emulsification tank is fixedly embedded on an operating platform on the top of the frame, and a ladder is connected between the operating platform and the frame to facilitate operators to go up and down the operating platform. The operating platform provides a fixed position for the emulsification tank.

[0012] Preferably, a protective fence is provided on the top outer edge of the operating platform to avoid the risk of operators falling when operating at height.

[0013] Preferably, the constant flow dripping mechanism further comprises an I-shaped support fixed to the top of the steel frame, a vertical mounting frame fixed to the I-shaped support, a T-shaped rod fixed to the top of the vertical mounting frame and used to fix the three-way valve A and the three-way valve B, and a three-way valve C fixed to the vertical mounting frame;

[0014] Two screw linear modules are respectively installed on both sides of the vertical mounting frame. The lifting seats on the two screw linear modules are fixedly connected to the bottom of the piston rod. The feed port A on the three-way valve A and the three-way valve B is connected to the oil phase storage box through the pipeline A. The discharge port A on the three-way valve A and the three-way valve B is respectively connected to the two feed ports B of the three-way valve C through the pipeline B. The inlet and outlet nozzles on the three-way valve A and the three-way valve B are connected to the sleeve, and the oil phase dripping tube is connected to the discharge port B of the three-way valve C.

[0015] Preferably, the motor on the screw linear module is driven to move the piston rod on the lifting seat up or down, thereby drawing the oil phase in the oil phase storage box into the casing or passing the oil phase in the casing through the pipeline B into the three-way valve C, the discharge port B and the oil phase dripping tube.

[0016] Preferably, the two sleeves are respectively fixed on both sides of the top of the vertical mounting frame and are located above the lead screw linear module.

[0017] Precise motor control enables minute piston rod movements, precisely controlling the speed and quantity of oil phase addition. The three-way valve allows for flexible adjustment of the oil phase flow to meet diverse production needs. The overall mechanism design ensures stable oil phase extraction and addition, helping to achieve a uniform and stable emulsion. The motor-driven mechanical movement replaces manual operation, improving operational safety.

[0018] Compared with the prior art, the technical effects and advantages of the utility model are:

[0019] This microcapsule preparation device for ink material production uses two linear actuators to precisely control the piston rod's speed and force, ensuring that the oil phase is added to the water phase at a constant rate. This design avoids problems such as emulsion instability or excess or insufficient oil phase caused by varying addition speeds, helping to form a uniform and stable emulsion and improving the quality and efficiency of microcapsules.

[0020] Two sets of screw linear modules, two sleeves and piston rods are set. When one screw linear module pushes the piston rod to withdraw the oil phase in the sleeve at a constant flow, the other screw linear module pushes the piston rod to move the oil phase in the oil phase storage box into the sleeve. Thus, the reciprocating alternating operation can achieve uninterrupted constant flow dripping of the oil phase. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0026] The following is combined with Figure 1-3 To further explain this application,

[0027] The present embodiment discloses a microcapsule preparation device for ink material production, comprising an emulsification tank 1 and a constant-flow dripping mechanism 5. The lid 2 on top of the emulsification tank 1 is provided with an opening 4 for inserting an oil phase dripping tube 3 into the emulsification tank 1. A steel frame 6 is fixed to the lid 2, and an agitator 7 is fixed to the steel frame 6, extending into the emulsification tank 1. The steel frame 6 provides additional structural stability, ensuring the robustness of the entire device during operation. The presence of the agitator 7 effectively mixes the oil phase and the aqueous phase, promoting the emulsification process, thereby improving the quality and efficiency of the microcapsules. The emulsification tank 1 is fixedly embedded in an operating platform 9 on the top of a frame 8. A ladder 10 is connected to the operating platform 9 and the frame 8 to facilitate operators to ascend and descend the operating platform 9. The operating platform 9 provides a fixed position for the emulsification tank 1, allowing operators to safely approach and operate the equipment. The provision of the operating platform 9 makes the entire device more compact, reduces workspace requirements, and improves work efficiency. A protective fence 11 is provided on the top outer edge of the operating platform 9. The protective fence 11 can prevent operators from mistakenly entering dangerous areas and avoid the risk of falling when operating at heights.

[0028] The constant flow dripping mechanism 5 is used to push the oil phase into the oil phase dripping tube 3 and slowly drip the oil phase toward the water phase in the tank through the oil phase dripping tube 3;

[0029] The constant flow dripping mechanism 5 includes two sleeves 51 for containing the oil phase, a piston rod 52 used in conjunction with the sleeve 51 to draw the oil phase into or out of the sleeve 51, and two screw linear modules 53 that drive the piston rod 52 to reciprocate in the sleeve 51 to push the oil phase in the sleeve 51 out or draw the oil phase into the sleeve 51.

[0030] The two screw linear modules 53 drive the piston rod 52 to rise or fall steadily, thereby drawing the oil phase into or out of the sleeve 51. After the oil phase is pushed out of the sleeve 51, it is slowly dripped into the water phase in the tank through the oil phase dripping pipe 3 at a constant flow rate.

[0031] The constant flow dripping mechanism 5 further includes an I-shaped support 54 fixed to the top of the steel frame 6, a vertical mounting frame 55 fixed to the I-shaped support 54, a T-shaped rod 58 fixed to the top of the vertical mounting frame 55 and used to fix the three-way valve A56 and the three-way valve B57, and a three-way valve C59 fixed to the vertical mounting frame 55;

[0032] The two screw linear modules 53 are respectively installed on both sides of the vertical mounting frame 55. The lifting seats 510 on the two screw linear modules 53 are fixedly connected to the bottom of the piston rod 52. The feed port A511 on the three-way valve A56 and the three-way valve B57 is connected to the oil phase storage box through the pipeline A515. The discharge port A512 on the three-way valve A56 and the three-way valve B57 is respectively connected to the two feed ports B513 of the three-way valve C59 through the pipeline B516. The inlet and outlet nozzles 514 on the three-way valve A56 and the three-way valve B57 are connected to the sleeve 51, and the oil phase drip tube 3 is connected to the discharge port B of the three-way valve C59.

[0033] The motor on the lead screw linear module 53 moves the piston rod 52 on the lifting base 510 upward or downward, thereby pumping the oil phase from the oil phase storage tank into the sleeve 51 or directing the oil phase from the sleeve 51 through the pipe B516 to the three-way valve C59, the discharge port B, and the oil phase dripping pipe 3. The two sleeves 51 are fixed to the top of the vertical mounting frame 55 on both sides and are located above the lead screw linear module 53.

[0034] Three-way valve A56, three-way valve B57 and three-way valve C59 are used to control the flow direction of the oil phase. By opening and closing different valves, the oil phase can be guided to the sleeve 51, three-way valve C59 or directly added to the water phase. The oil phase storage tank is used to store the oil phase and is connected to the three-way valve A56 and three-way valve B57 through pipeline A515 to ensure the source of the oil phase.

[0035] Two sets of screw linear modules 53 and two sleeves 51 and piston rod 52 are set. When one screw linear module 53 pushes the piston rod 52 to withdraw the oil phase constant flow in the sleeve 51, the other screw linear module 53 pushes the piston rod 52 to move and draw the oil phase in the oil phase storage box into the sleeve 51. Thus, the reciprocating alternating operation can realize uninterrupted constant flow dripping of the oil phase.

[0036] Precise control of the motor enables minute movements of the piston rod 52, precisely controlling the rate and amount of oil phase addition. The three-way valve allows flexible adjustment of the oil phase flow to meet diverse production needs. The overall mechanism design ensures stable extraction and addition of the oil phase, helping to produce a uniform and stable emulsion. The motor-driven mechanical movement replaces manual operation, improving operational safety.

[0037] In this microcapsule preparation device for ink material production, the two linear guide screw modules 53 in the constant-flow dripping mechanism 5 precisely control the speed and force of the piston rod 52, ensuring that the oil phase is dripped into the water phase at a constant rate. This control method avoids problems such as emulsion instability or excessive or insufficient oil phase caused by changes in dripping speed.

[0038] The reciprocating motion of the piston rod 52 in the sleeve 51 can accurately control the volume of the oil phase, so that the oil phase can be added to the water phase in the emulsification tank 1 through the oil phase dropper 3 at a stable flow rate. Since the oil phase is added at a constant rate, it helps to form a uniform oil-water mixture during the emulsification process, thereby improving the stability of the emulsion and the final quality of the microcapsules.

[0039] Constant flow addition can ensure that the oil phase is evenly distributed in the water phase, avoids the oil phase from agglomerating into large oil droplets, and helps to form a stable emulsion. By precisely controlling the droplet addition speed and amount of the oil phase, the microencapsulation process can be better controlled to obtain the expected microencapsulation product.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
