Examples

The utility model discloses a two-component dynamic stirring screw 122 valve, which is matched with figures 1 to 3, and is used for dynamically stirring and dispensing two glue solutions, wherein the stirring and dispensing are performed simultaneously.

The two-component dynamic stirring screw 122 valve comprises a main valve body 10 and a stirring seat 20, wherein an upper stirring channel and two first flow channels 41 respectively positioned on two sides of the stirring channel are arranged on the main valve body 10, a stirring shaft 30 is arranged in the stirring channel, a stator 11 and a rotor 12 rotating relative to the stator 11 are arranged in the first flow channels 41, and glue inlets are formed in the first flow channels 41. Glue solution enters the first flow channels 41 from a glue inlet (the glue inlet is positioned on the side wall of the top of the first flow channels 41 and is communicated with the external glue cylinder 50), the two first flow channels 41 are usually two different glue solutions, and the glue solution in the first flow channels 41 is conveyed to flow out of the first flow channels 41 under the rotation action of the rotor 12.

The stirring seat 20 is located at the lower end of the main valve body 10, the stirring seat 20 is provided with a stirring cavity 21, a lower stirring channel and two second flow channels 42 corresponding to the first flow channels 41 respectively, the stirring shaft 30 rotatably penetrates through the lower stirring channel and stretches into the stirring cavity 21, an inlet of the second flow channel 42 is communicated with the first flow channels 41, an outlet of the second flow channel 42 is communicated with the stirring cavity 21, the first flow channels 41 and the second flow channels 42 corresponding to the first flow channels are communicated form a glue inlet flow channel 40, the glue inlet flow channel 40 is a linear flow channel or is provided with at least one bending part, and the included angles of the bending parts are all larger than 120 degrees.

The glue solution flows from the first flow channel 41 into the second flow channel 42 under the conveying action of the rotor 12, and then flows into the stirring cavity 21, and the two glue solutions are combined in the stirring cavity 21. The stirring shaft 30 can rotate, the bottom end of the stirring shaft extends into the stirring cavity 21, and the stirring shaft 30 rotates to enable the two glues in the stirring cavity 21 to be mixed.

The glue solution enters the stirring cavity 21 through the first flow channel 41 and the second flow channel 42, and the first flow channel 41 and the second flow channel 42 which are communicated form a glue inlet flow channel 40, namely two sides of the stirring shaft 30 are respectively provided with the glue inlet flow channel 40. The glue inlet flow channel 40 is in a straight line or is provided with at least one bending part, and the included angles of the bending parts are all larger than 120 degrees, so that the glue inlet flow channel 40 cannot flow through right angles, the glue flow smoothness can be ensured, the glue pressure stability can be ensured, and the glue outlet quantity is more accurate.

The shape of the glue inlet channel 40 is the following: the glue inlet channel 40 is entirely straight or has a bend (non-straight). When the glue inlet flow channels 40 are straight, the two glue inlet flow channels 40 can be arranged vertically in parallel and also parallel to the stirring shaft 30, but because the glue inlet flow channels 40 are all required to be communicated with the stirring cavity 21, the stirring cavity 21 must be large enough (mainly the width in the horizontal direction) in this design, and thus insufficient glue mixing in the stirring cavity 21 may occur. When the glue inlet flow channels 40 are straight, the two glue inlet flow channels 40 can be inclined towards the direction of the stirring shaft 30 from top to bottom, i.e. the two glue inlet flow channels 40 are approximately V-shaped and are arranged at an included angle with the stirring shaft 30, so that glue solution can smoothly flow in the glue inlet flow channels 40, but the design is also applicable, but the design still has a problem that the size of the upper end of the whole valve body is larger (the distance between the upper ends of the two glue inlet flow channels 40 is larger), so that the volume of the whole valve body is larger. Preferably, the two glue inlet flow channels 40 are obliquely arranged from top to bottom in the direction of the stirring shaft 30, that is, the two glue inlet flow channels 40 are approximately V-shaped, and meanwhile, proper bending parts are designed, the included angle of the bending parts is as large as possible, so that the size of the upper end (the distance between the top ends of the main two glue inlet flow channels 40 is small) and the size of the lower end (the size of the stirring cavity 21 is small, and the size of the stirring shaft 30 is small, so that the glue in the stirring cavity 21 can be uniformly mixed) of the whole valve body is as small as possible.

In this embodiment, the glue inlet channel 40 is designed as follows: the two glue inlet flow channels 40 are symmetrically arranged (are symmetrically arranged about the stirring shaft 30), the first flow channel 41 is a straight flow channel with the lower end inclined towards the inner side of the stirring shaft 30, the second flow channel 42 comprises an upper bending flow channel 421 and a lower bending flow channel 422, the upper bending flow channel 421 is communicated with the first flow channel 41 and inclined towards the outer side of the stirring shaft 30 relative to the first flow channel 41, the upper bending flow channel 421 and the first flow channel 41 form a bending part, the lower bending flow channel 422 is communicated with the upper bending flow channel 421 and inclined towards the inner side of the stirring shaft 30 relative to the upper bending flow channel 421, and the lower bending flow channel 422 and the upper bending flow channel 421 form a bending part.

The overall trend of the glue inlet flow channel 40 is as follows: inclined toward the inside of the stirring shaft 30 from top to bottom. The lower bending flow passages 422 (straight flow passages) incline toward the inner side of the stirring shaft 30, so that the bottom ends (the bottom ends of the glue inlet flow passages 40) of the lower bending flow passages 422 are close to the stirring shaft 30 as much as possible, the stirring cavity 21 can be designed to be smaller corresponding to the stirring cavity 21 and the two lower bending flow passages 422, and the position size of the lower bending flow passages 422 can be designed to be smaller corresponding to the stirring seat 20. The first flow channel 41 is inclined toward the inner side of the stirring shaft 30 from top to bottom, and the upper end of the first flow channel 41 (linear flow channel) can be as close as possible under the condition that the upper end installation space is ensured (the installation space is needed for components such as a motor, etc.), the lower end of the first flow channel 41 (linear flow channel) is communicated with the lower bending flow channel 422 through the upper bending flow channel 421 (linear flow channel), and the upper bending flow channel 421 plays a role of angle compensation, so that the first flow channel 41 and the lower bending flow channel 422 are communicated.

Furthermore, the upper bending flow channel 421 and the first flow channel 41 form a bending part, the lower bending flow channel 422 and the upper bending flow channel 421 form a bending part, and the included angle (the included angle of the axes of the two flow channels is smaller than 180 degrees) of the bending part can reach more than 150 degrees through the design of the two bending parts while meeting the design space and the volume requirement. In this embodiment, the degrees of the included angles of the two bending portions are both about 160 degrees.

Because the stirring shaft 30 can rotate relative to the stirring shaft 30, there is a gap between the stirring shaft 30 and the stirring base 20, and in order to avoid leakage of the glue solution (with a certain pressure) in the stirring cavity 21 from the stirring channel, a seal between the stirring channel and the stirring shaft 30 needs to be made. The stirring seat 20 is spliced by the upper stirring block 22 and the lower stirring block 23, and the top end of the lower stirring block 23 is provided with the plug seal 231, so that the plug seal 231 is convenient to install due to the splicing design of the upper stirring block 22 and the lower stirring block 23. The upper stirring block 22 and the lower stirring block 23 are locked and fixed through bolts.

Further, the bottom of the lower stirring channel is V-shaped, and the sealing ring 232 is sleeved at the bottom of the stirring shaft 30 corresponding to the lower stirring channel. The V-shaped of the lower stirring channel corresponds to the V-shaped formed by the bottom ends of the two lower bending flow channels 422, the sealing ring 232 is sleeved at the bottom end (V-shaped part) of the stirring channel corresponding to the stirring shaft 30, the sealing ring 232 can be fixed without designing a groove for installing the sealing ring 232, and preferably, the sealing rings 232 are both V-shaped, two layers of sealing rings 232 are designed, and the sealing effect is improved. The design of the sealing ring 232 and the universal plug seal 231 further improves the sealing effect. When the stirring seat 20 is assembled, the sealing ring 232 and the universal plug seal 231 are firstly assembled to corresponding positions, and finally the upper stirring block 22 and the lower stirring block 23 are locked, so that the installation is convenient.

In this embodiment, the bending design of the glue inlet channel 40 and the splicing design of the stirring seat 20 are combined, the upper bending channel 421 is disposed on the upper stirring block 22, and the lower bending channel 422 is disposed on the lower stirring block 23, so that the production and processing of each individual stirring block (the upper stirring block 22 and the lower stirring block 23 are both straight channels) are facilitated. In addition, a sealing ring 232 (not shown in the figure) is disposed at the connection between the first flow channel 41 and the upper bending flow channel 421 and the connection between the upper bending flow channel 421 and the lower bending flow channel 422, and the sealing ring 232 is designed to ensure the tightness of the glue inlet flow channel 40.

Further, the first flow channel 41 extends to the upper stirring block 22, and thus the upper stirring block 22 is designed with the first flow channel 41 and the upper bending flow channel 421 at the same time, and correspondingly, for convenience in processing and assembly, the upper stirring block 22 is formed by splicing an upper part and a lower part.

A nozzle 61 which can be communicated with the stirring cavity 21 is arranged at the lower end of the stirring cavity and is used for spraying the finally stirred and mixed glue solution from the nozzle 61. Wherein, the stirring cavity 21 can be directly formed by the stirring seat 20, and the nozzle 61 is directly fixed on the stirring seat 20 and communicated with the stirring cavity 21; the stirring chamber 21 may be formed by the stirring base 20 and the nozzle 61.
