[0005] In order to solve the technical problem of low cleaning efficiency of the dynamic mixing valve in the above prior art, the utility model provides a dynamic mixing valve with an on-line cleaning function, which can be cleaned on-line without disassembly.

[0006] The technical solution adopted by the present utility model to solve the above technical problems is as follows: A dynamic mixing valve with an online cleaning function, including a valve body.

[0007] By providing the cleaning channel one and the cleaning channel two, the present utility model can realize the online cleaning of the diversion channel one, the diversion channel two, and the mixing cylinder without disassembling parts, with high cleaning efficiency.

The control channel one is respectively communicated with the adhesive inlet channel one and the diversion channel one, the control channel two is respectively communicated with the adhesive inlet channel two and the diversion channel two. Sealing members are axially movably arranged inside both the control channel one and the control channel two.

[0009] By providing the control channel one, the control channel two, and the sealing members, the present utility model can reliably control the corresponding glue to enter the mixing cylinder, avoiding the corresponding glue being sucked back into the mixing cylinder under the pressure difference fluctuation, which affects the bonding strength.

[0010] Furthermore, a cylinder one and a cylinder two are provided on the valve body. The piston rods of the cylinder one and the cylinder two are respectively connected to the corresponding sealing members.

The control channel one and the control channel two are symmetrically arranged inside the valve body. The included angles between the control channel one and the adhesive inlet channel one and between the control channel two and the adhesive inlet channel two are both a, and 40° ≤ a ≤ 50°.

[0017] Furthermore, the mixing cylinder is made of a transparent material. A cylinder sleeve is arranged outside the mixing cylinder. Detection grooves are arranged on the circumferential surface of the cylinder sleeve. A sensor is arranged on the cylinder sleeve. The sensor is an electromagnetic induction type sensor. The sensor is arranged opposite to the detection grooves. Detection protons are arranged at positions on the stirring blades opposite to the detection grooves. The detection protons are made of magnetic metal, and the sensor can detect the detection protons.

[0018] By arranging the sensor and the detection protons, the utility model can monitor the rotation of the stirring blades, timely detect the situation of the change in the rotation speed of the stirring blades or even jamming, and avoid outputting unqualified mixed glue.

[0019] Furthermore, a mounting ring is sleeved on the cylinder sleeve. Mounting holes are arranged along the radial direction of the mounting ring. Set screws are arranged in the mounting holes.

By setting a first cleaning flow channel and a second cleaning flow channel, it is possible to clean the first diversion channel, the second diversion channel, and the mixing cylinder online without disassembling parts, with high cleaning efficiency. Moreover, by setting the first cleaning flow channel and the second cleaning flow channel, the first diversion channel and the second diversion channel can be cleaned separately, avoiding the situation where glue remains in another glue channel when only one cleaning flow channel is set, resulting in incomplete cleaning. By setting a first control flow channel, a second control flow channel, and a seal, it is possible to reliably control the corresponding glue from entering the mixing cylinder, preventing the corresponding glue from being sucked back into the mixing cylinder under pressure difference fluctuations and affecting the bonding strength. By arranging the first control flow channel and the second control flow channel obliquely, the space occupied by the first cylinder and the second cylinder in the horizontal direction can be reduced, avoiding interference with other components. By setting a gasket to enhance the sealing effect of the seal, glue leakage can be prevented. By adopting a stirring blade with a multi-segment staggered structure, the mixing and conveying of glue can be achieved, enhancing the conveying capacity of the stirring blade for glue. By setting a sensor and a detection proton, the rotation of the stirring blade can be monitored, and the situation of the rotation speed change or even jamming of the stirring blade can be detected in a timely manner, avoiding the output of unqualified mixed glue.

Specific embodiments

[0030] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments of the present utility model. Obviously, the embodiments described below are only some of the embodiments of the present utility model, rather than all of them. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0031] As Figures 1 to 3 shown, this specific embodiment provides a dynamic mixing valve with an online cleaning function, including a valve body 8 and a mixing cylinder 10. The mixing cylinder 10 is arranged below the valve body 8, and a glue outlet nozzle is arranged below the mixing cylinder 10. A first glue inlet channel 7, a second glue inlet channel 3, a second diversion channel 20, and a first diversion channel 19 are arranged in the valve body 8. The first glue inlet channel 7 is communicated with the second diversion channel 20, and the first glue inlet channel 7 is communicated with the supply pump of glue A. The first glue inlet channel 7 and the second diversion channel 20 are communicated to form a channel for glue A. The second glue inlet channel 3 is communicated with the first diversion channel 19, and the second glue inlet channel 3 and the first diversion channel 19 are communicated to form a channel for glue B. The second glue inlet channel 3 is communicated with the supply pump of glue B. Both the second diversion channel 20 and the first diversion channel 19 are communicated with the mixing cylinder 10. A first cleaning flow channel 22 is communicated at a position where the second diversion channel 20 is close to the first glue inlet channel 7. The first cleaning flow channel 22 is communicated with a first one-way valve. A second cleaning flow channel 21 is communicated at a position where the first diversion channel 19 is close to the second glue inlet channel 3. The second cleaning flow channel 21 is communicated with a second one-way valve. Both the first one-way valve and the second one-way valve are communicated with the supply pump of the cleaning liquid. The supply pump of the cleaning liquid can pump cleaning liquid with a certain pressure into the first cleaning flow channel 22 and the second cleaning flow channel 21. The first one-way valve and the second one-way valve are used to supply the cleaning liquid.

[0032] In this specific embodiment, by providing the first cleaning channel 22 and the second cleaning channel 21, it is possible to clean the second diversion channel 20, the first diversion channel 19, and the mixing cylinder 10 online without disassembling the components, with high cleaning efficiency. Moreover, by providing the first cleaning channel 22 and the second cleaning channel 21, the second diversion channel 20 and the first diversion channel 19 can be cleaned separately, avoiding the situation where glue remains in one of the glue channels due to the setting of only one cleaning channel, resulting in incomplete cleaning.

[0033] As Figures 1 to 3 shown, since the mixing valve needs to output a single type of glue and mixed glue according to the working requirements, to prevent the glue from being sucked back due to pressure fluctuations inside the valve body 8 and affecting the bonding degree, in this specific embodiment, a first control channel 16 and a second control channel 18 are further provided inside the valve body 8. The first control channel 16 is respectively connected to the first glue inlet channel 7 and the second diversion channel 20, and the first glue inlet channel 7 and the second diversion channel 20 are located on both sides of the first control channel 16. The second control channel 18 is respectively connected to the second glue inlet channel 3 and the first diversion channel 19, and the second glue inlet channel 3 and the first diversion channel 19 are located on both sides of the second control channel 18. Seals 15 are axially movably provided inside the first control channel 16 and the second control channel 18. After such a setting, after the corresponding amount of glue is output, the seal 15 moves to block the corresponding channel, preventing the glue remaining in the first glue inlet channel 7 or the second glue inlet channel 3 from entering the mixing cylinder 10 and affecting the glue bonding strength. Specifically, a first cylinder 6 and a second cylinder 4 are provided on the valve body 8, and the piston rods of the first cylinder 6 and the second cylinder 4 are respectively connected to the corresponding seals 15. To further improve the sealing performance, sealing gaskets 17 are provided inside the first control channel 16 and the second control channel 18. To avoid blocking the first glue inlet channel 7 and the second glue inlet channel 3, the two sealing gaskets 17 are respectively located in the mid-front part (along the glue flow direction) of the connection between the first glue inlet channel 7 and the first control channel 16 and the connection between the second glue inlet channel 3 and the second control channel 18. After such a setting, the sealing gasket 17 will not block the corresponding glue channels. The inner hole of the sealing gasket 17 is a tapered hole, the seal 15 is of a tapered structure, and the seal 15 is in shape fit with the sealing gasket 17.

[0034] As Figure 1 and Figure 3 shown, to reduce the space occupied by this mixing valve and facilitate installation and use, in this specific embodiment, the first glue inlet channel 7 and the second glue inlet channel 3 are respectively horizontally arranged on both sides of the valve body 8, the first control channel 16 and the second control channel 18 are symmetrically arranged inside the valve body 8, the included angle between the first control channel 16 and the first glue inlet channel 7 and the included angle between the second control channel 18 and the second glue inlet channel 3 are both a, where 40° ≤ a ≤ 50°. In this specific embodiment, a is 45°.

[0035] In the prior art, the glue discharging power of the mixing valve comes from the pushing of the supply pump. However, when the viscosity of some glues is relatively high, the pushing resistance is large and the glue discharging speed is low. Therefore, as Figure 4 and Figure 6 shown, in this specific embodiment, a stirring blade 23 is arranged in the mixing cylinder 10. The stirring blade 23 includes multiple spiral blade units 24, and every two adjacent blade units 24 are distributed in a staggered manner at 90°. After such arrangement, the shearing effect on the glue is enhanced, the stirring, mixing and conveying effects of the stirring blade 23 on the mixed glue are enhanced, the conveying effect on the glue is enhanced, and the glue discharging speed is increased. The driving shaft 13 of the stirring blade 23 penetrates upward through the valve body 8 and extends out. The upper shaft end of the driving shaft 13 is connected with a driving motor 1 through a coupling 5. The coupling 5 is arranged in a protective cover 2 on the upper part of the valve body 8, and the driving motor 1 is arranged on the upper part of the protective cover 2. The driving motor 1 can adjust the rotation speed through an electronic control module to be applicable to glues with different viscosities.

[0036] In order to be able to monitor the rotation speed of the stirring blade 23 and avoid the problems of reduction in the rotation speed of the stirring blade 23 and jamming, as Figure 4 and Figure 5 shown, in this specific embodiment, the mixing cylinder 10 is made of a transparent material. A cylinder sleeve 26 is arranged outside the mixing cylinder 10. A detection groove 12 is arranged on the circumferential surface of the cylinder sleeve 26. A sensor 11 is arranged on the cylinder sleeve 26. The sensor 11 adopts an electromagnetic induction type sensor. The sensor 11 is arranged opposite to the detection groove 12. A detection proton 27 is arranged at a position on the stirring blade 23 opposite to the detection groove 12. The detection proton 27 adopts a magnetic metal. The sensor 11 can detect the detection proton 27. The sensor 11 is electrically connected with the electronic control module. By the sensor 11 detecting the signal sent by the detection proton 27, the electronic control module can measure the rotation speed of the stirring blade 23, and then discover the problem of abnormal rotation speed of the stirring blade 23, reminding people to process it in time. In this specific embodiment, the sensor 11 adopts an inductive proximity sensor 11, and the detection proton 27 adopts an iron shaft. The iron shaft horizontally penetrates through the corresponding blade unit 24. To ensure the sensitivity, the iron shaft should not be too thick. In this specific embodiment, the diameter is 2 mm. Further, to prevent the sensor 11 from rotating, a mounting ring 9 is sleeved on the cylinder sleeve 26. Mounting holes are arranged along the radial direction of the mounting ring 9. Set screws are arranged in the mounting holes. The set screws are abutted against the circumferential surface of the cylinder sleeve 26. A mounting screw hole is arranged at a position on the mounting ring 9 opposite to the detection groove 12. The sensor 11 is threadedly connected with the mounting screw hole.

[0037] The online cleaning process of the dynamic mixing valve with the online cleaning function is as follows:

[0038] When cleaning is required, cylinder one 6 and cylinder two 4 extend, the seal 15 abuts against the gasket 17, blocking the first glue inlet channel 7 and the second glue inlet channel 3 to prevent the cleaning liquid from entering. Then, the cleaning liquid supply pump rotates, and the cleaning liquid enters the mixing cylinder 10 through the first one-way valve and the second one-way valve respectively from the first guiding channel and the second guiding channel, performs high-pressure cleaning on the corresponding glue channels, and flows out from the glue outlet nozzle of the mixing cylinder 10.

[0039] It can be seen from the above specific embodiments that the present utility model has the following beneficial effects:

[0040] 1. By providing the first cleaning flow channel 22 and the second cleaning flow channel 21, it is possible to clean the second guiding channel 20, the first guiding channel 19 and the mixing cylinder 10 online without disassembling the components, with high cleaning efficiency. Moreover, by providing the first cleaning flow channel 22 and the second cleaning flow channel 21, the second guiding channel 20 and the first guiding channel 19 can be cleaned respectively, avoiding the situation where a cleaning flow channel is provided and glue remains in the other glue channel, resulting in incomplete cleaning.

[0041] 2. By providing the first control flow channel, the second control flow channel and the seal 15, the corresponding glue can be reliably controlled to enter the mixing cylinder 10, avoiding the corresponding glue being sucked back into the mixing cylinder 10 under the pressure difference fluctuation, which affects the bonding strength.

[0042] 3. By obliquely arranging the first control flow channel 16 and the second control flow channel 18, the space occupied by cylinder one 6 and cylinder two 4 in the horizontal direction can be reduced, avoiding interference with other components.

[0043] 4. By providing the gasket 17, the sealing effect of the seal 15 is enhanced to prevent glue leakage.

[0044] 5. By adopting the stirring blades 23 with a multi-segment staggered structure, the mixing and conveying of the glue can be realized, enhancing the conveying ability of the stirring blades 23 for the glue.

[0045] 6. By providing the sensor 11 and the detection proton 27, the rotation condition of the stirring blades 23 can be monitored, and the situation of speed change or even jamming of the stirring blades 23 can be detected in time, avoiding the output of unqualified mixed glue.

[0046] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
