Description

Technical Field

[0001] This application relates to the field of liquid material mixing technology, and in particular to a static mixing tube device. Background Technology

[0002] A static mixing tube, also known as a glue mixing tube, is used for the automatic mixing of two-component adhesive materials. It is mainly used at the front end of a glue gun or at the dispensing nozzle of a dispensing device. Currently, most static mixing tubes adopt a straight-pipe series structure, in which the mixing tube is directly connected in series with the main delivery pipeline as an independent pipe section. This structure usually requires additional accessories such as check valves or ball valves to be installed on the pipelines before and after the mixing tube to achieve functions such as fluid control, backflow prevention, and system connection.

[0003] One of the core components of a static mixing pipe is the mixing core. As a critical component that directly contacts the fluid and withstands shear forces, it is a consumable part and needs to be replaced periodically according to actual operating conditions. In the current straight-pipe series structure, replacing the mixing core requires completely disconnecting the connections at both ends of the mixing pipe and removing the entire mixing pipe from the delivery pipeline before the old mixing core can be removed and the new one installed. This operation is cumbersome and time-consuming. Moreover, during the replacement process, the mixing pipe is completely separated from the pipes connected before and after it. At this time, the inlet and outlet parts of the pipes are in a separated state, causing the separated pipe ends to be suspended in the air. There is a risk that the pipes may loosen or fall due to gravity or external forces, posing a safety hazard to maintenance personnel. Utility Model Content

[0010] According to some embodiments of this application, the mixing channel includes a first mixing channel and a second mixing channel connected in series therewith. The fluid medium flows in from the input channel and passes sequentially through the first mixing channel, the second mixing channel, the output channel, and the discharge channel. The first mixing channel is provided with a first mixing core for initial mixing of the fluid medium flowing in from the input channel. The outlet of the first mixing channel is connected to the inlet of the second mixing channel, so that the fluid medium after initial mixing enters the second mixing channel.

[0011] According to some embodiments of this application, the first and second mixing cores are screw cores, and the surfaces of the first and second mixing cores have two sets of spiral protrusions with opposite directions of rotation.

[0012] According to some embodiments of this application, one end of the mixing tube carrier is detachably connected to the valve body, and the other end is connected to an end cap. The end cap is provided with a guide groove, which connects the outlet of the first mixing channel and the inlet of the second mixing channel.

[0013] According to some embodiments of this application, the mixing tube carrier is provided with a cooling water channel, which is used to cool the mixed fluid medium.

[0014] According to some embodiments of this application, the cooling water channel is disposed between the first mixing channel and the second mixing channel, and is not connected to either of them, and the cooling water channel is arranged in a spiral or serpentine shape.

[0029] Reference Figures 1 to 6 The following are preferred embodiments of this application.

[0030] A static mixing tube device, comprising: The valve body 100 has an independent input channel 110 and an output channel 120 inside.

[0031] The valve body 100 is provided with two one-way valve modules 200. The surface of the one-way valve module 200 is provided with an inlet 210 for the fluid medium to flow in. The two one-way valve modules 200 are respectively provided with a first one-way valve 220 and a second one-way valve (not shown). The first one-way valve 220 and the second one-way valve are respectively connected to the input channel 110. The first one-way valve 220 and the second one-way valve have the same structure. The first one-way valve 220 and the second one-way valve are both provided with one-way valve cores. The fluid medium is only allowed to enter the input channel 110 from the inlet 210 through the first one-way valve 220 and the second one-way valve respectively, and the fluid medium is not allowed to flow out from the input channel 110.

[0032] A mixing tube carrier 400 is connected to the valve body 100. The mixing tube carrier 400 has a mixing channel inside. The inlet of the mixing channel is connected to the input channel 110, and the outlet of the mixing channel is connected to the output channel 120. The inlet and outlet of the mixing channel are located on the same side of the mixing tube carrier 400. At least one mixing core for mixing fluid media is provided in the mixing channel.

[0033] The output component 500 is connected to the bottom of the valve body 100. The output component 500 has an internal discharge channel 510, which is connected to the output channel 120 for discharging the mixed fluid medium. A third check valve 300 is provided at the connection between the output channel 120 and the discharge channel 510 to prevent the mixed fluid medium from flowing back into the valve body or the mixing tube carrier. The outlet of the discharge channel 510 is provided with an output port 520. The output component 500 is connected to the bottom of the valve body 100 through an output connector 530, which is a clamp.

[0034] Furthermore, the first check valve 220 and the second check valve are symmetrically arranged on both sides of the valve body 100, which can achieve a balanced distribution of the feed flow channel and facilitate the installation and connection of external pipelines.

[0035] A rotary valve assembly is provided between the inlet of the output channel 120 and the third one-way valve 300. The rotary valve assembly is used to control the opening and closing of the fluid medium flow path between the output channel 120 and the discharge channel 510. Specifically, the rotary valve assembly includes a valve 800 and a rotary drive 900. The valve 800 is located in the output channel 120, and the output end of the rotary drive 900 is connected to the valve 800 and can drive the valve core 810 in the valve 800 to rotate by an angle, thereby controlling the outflow of the fluid medium in the output channel 120.

[0036] More specifically, valve 800 is a butterfly check valve, and the rotary drive 900 is a motor, electromagnetic actuator, cylinder, or hydraulic cylinder, capable of driving the valve core inside the butterfly check valve to rotate 90 degrees to open and close the output channel 120. The butterfly check valve includes a valve body and a valve stem connected together. The valve body is located inside the output channel 120, and one end of the valve stem is connected to the output end of the rotary drive 900, while the other end protrudes outside the valve body 100 and is provided with a removable valve end cap 820, which is fixed to the surface of the valve body 100 by threads or flanges.

[0037] Under normal circumstances, when the valve core 810 is perpendicular to the output channel 120, that is, when the rotation angle is 0°, the valve 800 is in the closed state, preventing the fluid medium from passing through. When the valve core 810 rotates under the drive of the rotary drive 900, rotating from 0° to 90°, after the valve core 810 rotates 90°, it is parallel to the output channel 120, and the valve 800 is in the fully open state, allowing the fluid medium to pass through.

[0038] The mixing channel includes a first mixing channel 410 and a second mixing channel 420 connected in series therewith. The fluid medium flows in from the input channel 110, passes through the first mixing channel 410, the second mixing channel 420, the output channel 120, and the discharge channel 510 in sequence, and finally flows out from the output port 520. The first mixing channel 410 is provided with a first mixing core 411 for initial mixing of the fluid medium flowing in from the input channel 110. The outlet of the first mixing channel 410 is connected to the inlet of the second mixing channel 420, so that the fluid medium after initial mixing enters the second mixing channel 420. The second mixing channel 420 is provided with a second mixing core 421 for secondary mixing of the fluid medium that has initially mixed in the first mixing channel 410. The outlet of the second mixing channel 420 is connected to the inlet of the output channel 120, and the outlet of the output channel 120 is connected to the inlet of the discharge channel 510.

[0039] Furthermore, the first mixing core 411 and the second mixing core 421 are screw cores. The surfaces of the first mixing core 411 and the second mixing core 421 have two sets of spiral protrusions with opposite directions of rotation. When the fluid medium passes through the first mixing core 411 and the second mixing core 421, it will generate a rotational cutting effect on the fluid medium to achieve mixing of the fluid medium.

[0040] Furthermore, one end of the mixing tube carrier 400 is detachably connected to the valve body 100, and the other end is connected to an end cap 600. The end cap 600 is provided with a guide groove 610, which connects the outlet of the first mixing channel 410 and the inlet of the second mixing channel 420. The first mixing channel 410 and the second mixing channel 420 are connected.

[0041] The mixing tube carrier 400 is provided with a cooling water channel 700, which is located between the first mixing channel 410 and the second mixing channel 420 and is not connected to either of them. Specifically, the cooling water channel 700 is arranged in a spiral or serpentine shape inside the mixing tube carrier 400. The mixing tube carrier 400 is provided with a cooling water inlet 710 and a cooling water outlet 720, which are respectively connected to an external cooling system. This allows the cooling water to conduct heat through the inner wall of the mixing tube carrier 400 to the adjacent first mixing channel 410 and second mixing channel 420 during the flow process, thereby effectively removing the heat generated during the mixing of the fluid medium and cooling the mixed fluid medium.

[0042] Furthermore, the fluid medium flowing into the two one-way valve modules 200 is liquid silicone, which is a liquid material with two different components. The valve body 100 is connected to the one-way valve module 200, the mixing tube carrier 400 and the end cap 600 by threaded connection. Sealing mechanisms such as sealing rings can also be provided at the connection to further prevent fluid medium leakage.

[0043] The output port 520 of the output component 500 in this application is connected to the glue inlet of the injection molding machine barrel, thereby conveying the two mixed liquid materials into the barrel to complete the feeding process.

[0044] This application integrates a mixing tube carrier and an output component onto the valve body. The mixing tube carrier contains a mixing channel for mixing the input fluid medium. By integrating all devices onto the same valve body, the entire process of fluid medium control from input, mixing to output is achieved. When the mixing core in the mixing channel needs to be replaced, the connection between the mixing tube carrier and the valve body can be disassembled to remove the replacement mixing core. During the replacement process, the mixing tube carrier remains connected to the pipes before and after it, eliminating the need to disconnect the pipelines. This simplifies the replacement process, reduces the number of connection points between pipelines, and reduces the risk of leakage. A first, second, and third check valve are provided to ensure unidirectional flow of the fluid medium within the fluid medium channel, guaranteeing that the fluid medium can only flow into the valve body from the outside and preventing backflow or back-current during shutdown or pressure fluctuations. A rotary drive component rotates the valve core inside the valve to open and close the output channel, thereby controlling the outflow of the fluid medium. Finally, a cooling water structure is provided to cool the mixed fluid medium.
