[0066] The inclined double-component double-piezoelectric ceramic dispensing valve device 1000 of the present application is described in detail below with reference to the accompanying drawings.

[0067] Referring to Figures 1 to 5 As shown in the drawings, according to the inclined double-component double-piezoelectric ceramic dispensing valve device 1000 provided by the embodiment of the present application, it comprises a hollow dispensing head with a stretching inlet 101 opened downward at the top and a glue outlet hole 102 opened at the bottom, a glue closing punch pin 20, a valve body 30 for driving the glue closing punch pin 20 to move up and down to correspondingly open / close the glue outlet hole 102, a connecting frame 40 and an inclined double-component glue liquid storage and mixing device 50.

[0068] The hollow glue dispensing head is fixed at the bottom of the valve body 30; the glue closing punch pin 20 is arranged between the hollow glue dispensing head and the valve body 30, the lower end of the glue closing punch pin 20 is inserted into the hollow glue dispensing head from the extension port 101, the outer diameter of the glue closing punch pin 20 is smaller than the inner diameter of the hollow glue dispensing head and larger than the inner diameter of the glue outlet hole 102; the glue inlet hole 103 is obliquely arranged on the top of the hollow glue dispensing head and penetrates to the middle part of the hollow glue dispensing head, and the glue inlet hole 103 is adjacent to the outer side wall of the valve body 30.

[0069] The connecting frame 40 is fixed on the upper part of the valve body 30; the obliquely arranged dual-component glue storage and mixing device 50 is fixed on the connecting frame 40 and is located beside the valve body 30, and the lower end of the obliquely arranged dual-component glue storage and mixing device 50 is directly connected to the glue inlet hole 103.

[0070] Based on the above, it can be clearly seen that the application is mainly used as an obliquely arranged dual-component dual-piezoelectric ceramic glue dispensing valve device 1000 in specific implementation.

[0071] Specifically, when the application is applied, the application is assembled according to the structure described above, a certain proportion of two different glue liquids are pre-installed in the obliquely arranged dual-component glue storage and mixing device 50, and then the two different glue liquids of the corresponding certain proportion are mixed, then the valve body 30 is started, the valve body 30 drives the glue closing punch pin 20 to move up and down to correspondingly open / close the glue outlet hole 102, so that the mixed glue liquid can be discharged from the glue outlet hole 102 to realize dispensing on the surface of the product that needs to be dispensed.

[0072] Obviously, for the use of the above application, it has the following technical effects:

[0073] Because the glue inlet hole 103 is obliquely arranged on the top of the hollow glue dispensing head and penetrates to the middle part of the hollow glue dispensing head, the glue inlet hole 103 is adjacent to the outer side wall of the valve body 30, the obliquely arranged dual-component glue storage and mixing device 50 is fixed on the connecting frame 40 and is located beside the valve body 30, and the lower end of the obliquely arranged dual-component glue storage and mixing device 50 is directly connected to the glue inlet hole 103, so that the travel of the glue guide flow channel formed between the glue inlet hole 103 and the middle part of the hollow glue dispensing head is very short and can be ignored, so that the mixed glue liquid flowing therein can be quickly used up each time, so that it is not easy to solidify and block, the replacement frequency of the hollow glue dispensing head is low, and the use reliability and service life of the application are good.

[0074] Furthermore, the above optimization design makes the whole application have strong practicability and good use effect.

[0075] Further, in specific implementation, according to the above Figure 2 andFigure 4 As shown, according to one embodiment of the utility model, the oblique double-component glue solution storage and mixing device 50 includes a first glue barrel 501, a second glue barrel 502, and an oblique glue solution mixing pipe 503.

[0076] The first glue barrel 501 and the second glue barrel 502 are arranged side by side and fixed on the connecting frame 40. The upper end of the oblique glue solution mixing pipe 503 is connected to the lower ends of the first glue barrel 501 and the second glue barrel 502, and the lower end of the oblique glue solution mixing pipe 503 is directly inserted into the glue inlet hole 103.

[0077] Preferably, in the technical solution, continue to refer to Figure 2 and Figure 4 As shown, according to one embodiment of the utility model, the lower end of the first glue barrel 501 is provided with a first glue discharge head 5011, and the lower end of the second glue barrel 502 is provided with a second glue discharge head 5021. The upper end of the oblique glue solution mixing pipe 503 is provided with a funnel-shaped connecting seat 5031 which is adaptively fixed outside the first glue discharge head 5011 and the second glue discharge head 5021.

[0078] It should be noted that the first glue barrel 501 and the second glue barrel 502 are used to correspondingly install two different glue solutions, such as A glue and B glue. The mixing ratio can be controlled by designing the first glue barrel 501 and the second glue barrel 502 to be different sizes, and setting the inner diameters of the first glue discharge head 5011 and the second glue discharge head 5021 at the bottom to be different sizes, so as to control the amount of glue discharged downward per unit time, so as to finally realize the mixing according to the preset ratio and flow downward from the oblique glue solution mixing pipe 503.

[0079] As for the oblique glue solution mixing pipe 503 mentioned above, its internal structure can be the same as the glue solution mixing pipe internal structure provided in the utility model patent "Double-component glue dispensing device" with the patent number "202322981574.9" of the prior application of the present patent applicant. It is a common prior art, so its details are not described in detail here.

[0080] Further, in specific implementation, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the utility model, the application further includes a glue solution cooling member A60.

[0081] The glue solution cooling member A60 can be wrapped around the oblique glue solution mixing pipe 503 and fixed on the valve body 30.

[0082] Further, in specific implementation, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , according to one embodiment of the utility model, the application further includes glue solution cooling component B70;

[0083] Among them, the glue solution cooling component B70 can be opened and covered outside the lower part of the hollow point glue head, and the glue solution cooling component B70 is provided with a through hole 701 that is adapted to the downward penetration of the lower end of the hollow point glue head.

[0084] Therefore, it can be clearly seen that:

[0085] On the one hand, by setting the glue solution cooling component A60, it is convenient to cool the mixed glue flowing into the inclined glue mixing pipe 503, and a low-temperature environment is created to avoid solidification due to high temperature, and since the glue solution cooling component A60 is openable and covered outside the inclined glue mixing pipe 503, when it is opened, it is convenient to quickly disassemble, replace or maintain the inclined glue mixing pipe 503 and other structural parts, so that the application is very convenient to use.

[0086] On the other hand, by setting the glue solution cooling component B70, it is convenient to cool the mixed glue flowing into the hollow point glue head pipe, and a low-temperature environment is created to avoid solidification due to high temperature, and since the glue solution cooling component B70 is openable and covered outside the lower part of the hollow point glue head, when it is opened, it is convenient to quickly disassemble, replace or maintain the hollow point glue head and other structural parts, so that the application is further very convenient to use.

[0087] It should be noted here that the glue solution cooling component A60 and the glue solution cooling component B70 correspond to the structure of the glue solution cooling component A60 and the glue solution cooling component B70 set in the utility model patent "Double-component point glue device" with the patent number "202322981574.9" of the prior application of the present patent applicant, and they are common in the prior art, so their details are not described in detail here.

[0088] In addition, in specific implementation, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , according to one embodiment of the utility model, the upper part of the connecting frame 40 is movably provided with a openable clamping part 401, and the upper end of the first glue barrel 501 and the upper end of the second glue barrel 502 are detachably clamped in the openable clamping part 401.

[0089] Therefore, when the openable fastener 401 is opened, the upper ends of the first glue tank 501 and the second glue tank 502 are detached; conversely, when the openable fastener 401 is closed, the upper ends of the first glue tank 501 and the second glue tank 502 are fixed. The structure of the openable fastener 401 is basically the same as that of the hollow fastener in the utility model patent "Two-component dispensing device" with patent number "202322981574.9" filed by the patent applicant in the prior art. Since it is common in the prior art, its details will not be described in detail here.

[0090] Furthermore, in this technical solution, compared with... Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the present utility model, the valve body 30 has a valve port 301 at the bottom, the top of the sealing pin 20 extends upward into the valve port 301, and the bottom of the valve body 30 is rotatably connected to a valve head seat 303 that fits against its lower bottom surface through a rotating shaft 302. The valve head seat 303 has a groove 3031 facing the valve port 301 on its upper top surface, and an opening 30311 is opened downward in the middle of the bottom of the groove 3031.

[0091] The hollow dispensing head is fitted into the slot 3031 at its upper part, and its lower half extends downward from the through-hole 30311. The valve head seat 303 is provided with an upwardly bent barb 3032 at its end, and the valve body 30 is provided with a movable latch 304 at its bottom to secure the barb 3032. When the movable latch 304 is pried open to move away from the barb 3032, the valve head seat 303 can rotate from the horizontal direction downward to the vertical direction.

[0092] Therefore, by setting the valve head seat 303, it is easy to fix the hollow dispensing head. When the movable latch 304 is pried to make it move away from the barb 3032, the valve head seat 303 can rotate from the horizontal direction downward to the vertical direction. In this way, it is also convenient for the hollow dispensing head to be taken out of the slot 3031.

[0093] Furthermore, in specific implementation, we will continue to refer to... Figure 4 , Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, the valve body 30 has a first cavity 305 arranged vertically inside, and a second cavity 306 connected to the bottom of the first cavity 305 to form an L-shaped structure; the end of the second cavity 306 is located directly above the valve port 301 and communicates with the valve port 301.

[0094] The first cavity 305 contains a first piezoelectric ceramic component 307 and a second piezoelectric ceramic component 308 arranged vertically side by side. The bottom of the first piezoelectric ceramic component 307 is cut upward to form a first arc-shaped groove 3071. The bottom of the second piezoelectric ceramic component 308 is cut upward to form a second arc-shaped groove 3081.

[0095] Therefore, in this application, the reference is still made. Figure 5 , Figure 2 and Figure 4 As shown, the bottom of the second cavity 306 has an upwardly protruding rotating shaft 309 located directly below the first arc-shaped groove 3071 and the second arc-shaped groove 3081, and a lever 310 is horizontally fixed on the rotating shaft 309; the upper part of the first end of the lever 310 is correspondingly provided with a first rotating protrusion 3101 that abuts against the first arc-shaped groove 3071 and a second rotating protrusion 3102 that abuts against the second arc-shaped groove 3081; the top of the sealing pin 20 protrudes outward to form an outer edge 201; the second end of the lever 310 is bent downward to form a downward pressing head 3103 that abuts against the top surface of the outer edge 201;

[0096] Based on this, in this application, a hollow fixing plug 80 is fitted into the upper part of the slot 3031. The upper part of the hollow fixing plug 80 is open and the bottom center is provided with a guide opening 801 facing the extension opening 101. The sealing pin 20 passes through the guide opening 801. A pressure relief spring 90 is provided between the lower bottom surface of the outer edge 201 and the inner bottom surface of the hollow fixing plug 80 and is sleeved on the upper part of the sealing pin 20.

[0097] Initially, the pressure relief spring 90 is in a compressed state, and the lower end of the glue-closing strike pin 20 is in the lowest position to close the glue outlet 102;

[0098] In this regard, it is clear that this application uses a dual piezoelectric ceramic valve to control the upward tilting of the first and second ends of the lever 310 back and forth, so as to drive the glue-closing striker 20 to move up and down to open / close the glue outlet 102 of the valve body 30. Using a dual piezoelectric ceramic valve to replace the traditional operation method of spring plus single piezoelectric ceramic valve can make the response speed fast and the accuracy high, because the elastic force of the spring is unstable and the reaction speed is slow when the spring is stretched and deformed.

[0099] Specifically, the working principle of the valve body 30 described in this application is as follows:

[0100] Firstly, at the initial time, the slow compression spring 90 is in the compressed state, the glue closing plunger 20 lower end is in the lowest position to close the glue outlet hole 102, at this time, the first piezoelectric ceramic piece 307 is preset stroke upward movement and the second piezoelectric ceramic piece 308 is preset stroke downward movement, so that the lever 310 first end is upturned and the second end is downturned, to press down the glue closing plunger 20 through the lower pressing head 3103, so that its lower end is in the lowest position to close the glue outlet hole 102.

[0101] Then, the first piezoelectric ceramic piece 307 is preset stroke downward movement and the second piezoelectric ceramic piece 308 is preset stroke upward movement, so that the lever 310 first end is downturned and the second end is upturned, at this time, the lower pressing head 3103 will upwardly away from the glue closing plunger 20 upper top surface, that is, upwardly away from the glue closing plunger 20 outer edge 201 upper top surface, the slow compression spring 90 will be elastically reset to upwardly lift the glue closing plunger 20, at this time, the glue closing plunger 20 lower end is upwardly moved to open the glue outlet hole 102, so as to facilitate the glue liquid flowing into the hollow glue dispensing head to be downwardly discharged from the glue outlet hole 102.

[0102] The above-mentioned related steps are cyclically operated, that is, the glue closing plunger 20 can be frequently upwardly and downwardly moved to open / close the glue outlet hole 102 of the valve body 30 according to the preset frequency to realize intermittent dispensing operation on the product surface.

[0103] Obviously, for the above-mentioned valve body 30 of the present application, it will have the following effects when in use:

[0104] On the one hand, by setting the slow compression spring 90, when it is elastically reset, it can better assist the upward movement of the glue closing plunger 20 to open the glue outlet hole 102, and when it is compressed, it can provide slow compression force, so that the glue closing plunger 20 will not be instantaneously pushed downward, so that its lower end is not easily abraded by strong impact force when contacting the inner end of the glue outlet hole 102, so that the service life is long.

[0105] On the other hand, since the first piezoelectric ceramic piece 307 is formed with a first arc-shaped groove 3071 by upward cutting at the bottom, the second piezoelectric ceramic piece 308 is formed with a second arc-shaped groove 3081 by upward cutting at the bottom, the second cavity 306 is upwardly protruded with a rotating shaft 309 directly below the first arc-shaped groove 3071 and the second arc-shaped groove 3081, and a lever 310 is horizontally fixed on the rotating shaft 309, the first end of the lever 310 is correspondingly provided with a first rotating protrusion 3101 abutting against the first arc-shaped groove 3071 and a second rotating protrusion 3102 abutting against the second arc-shaped groove 3081, so that the first end and the second end of the lever 310 can swing stably, and the abutting stability between the first end and the second end and the bottom of the first piezoelectric ceramic piece 307 and the bottom of the second piezoelectric ceramic piece 308 is good and not prone to dislocation.

[0106] Furthermore, through the above-mentioned optimization design, the use effect of the whole application can be effectively improved.

[0107] Preferably, in the technical solution, according to the valve body 30, a first adjusting screw hole 311 and a second adjusting screw hole 312 are arranged on the top of the valve body 30, the first adjusting screw hole 311 is communicated with the first cavity 305 and faces the top of the first piezoelectric ceramic piece 307, and the second adjusting screw hole 312 faces the top of the second piezoelectric ceramic piece 308. Figure 5 Figure 2 Figure 4 Figure 5 Figure 5

[0108] The first adjusting screw hole 311 is screwed with a first adjusting screw 313 from top to bottom, the first adjusting screw 313 is used to adjust the pre-tightening force of the first piezoelectric ceramic piece 307, and the bottom of the first adjusting screw 313 abuts against the top of the first piezoelectric ceramic piece 307.

[0109] The second adjusting screw hole 312 is screwed with a second adjusting screw 314 from top to bottom, the second adjusting screw 314 is used to adjust the pre-tightening force of the second piezoelectric ceramic piece 308, and the bottom of the second adjusting screw 314 abuts against the top of the second piezoelectric ceramic piece 308.

[0110] Therefore, for the first piezoelectric ceramic piece 307 and the second piezoelectric ceramic piece 308, the pre-tightening force in the up-down direction can be adjusted to control the up-down movement stroke in the subsequent work, so as to adjust the frequency of the up-down movement of the glue injection needle 20, and the amount of mixed glue liquid discharged from the glue injection hole 102 can be flexibly controlled, and the application is more flexible to use.

[0111] ​Meanwhile, the first adjusting screw 313 and the second adjusting screw 314 are both moved in the up-down direction to realize corresponding adjustment of the pre-tightening force of the first piezoelectric ceramic piece 307 and the second piezoelectric ceramic piece 308, so that, compared with the traditional operation mode of pushing the top inclined surface of the piezoelectric ceramic valve laterally, the operation mode of the present application is not easy to wear the top of the first piezoelectric ceramic piece 307 and the top of the second piezoelectric ceramic piece 308, and also makes the first piezoelectric ceramic piece 307 and the second piezoelectric ceramic piece 308 have better holding force in the vertical direction and are not easy to be tilted laterally due to the top being pushed laterally, so that they both have good stability.

[0112] It should be noted that, in specific implementation, according to the inclined double-component double-piezoelectric ceramic dispensing valve device 1000 provided by the embodiment of the present application, the model of the valve body 30 is PZ-J300, and the hollow dispensing head is preferably made of Teflon material, so that it has strong inertness and smooth inner wall and is not easy to stick glue, so that when the mixed glue flows out of the glue outlet hole 102, the inner wall is not easy to stick to the glue and is not easy to be blocked.

[0113] Other embodiments and the like are not exemplified here.

[0114] In summary, the inclined double-component double-piezoelectric ceramic dispensing valve device 1000 provided by the present application, in specific implementation, because the glue inlet hole 103 is obliquely provided in the hollow dispensing head top beside the extension inlet 101 and penetrates to the inner middle part, the glue inlet hole 103 is next to the outer wall of the valve body 30, the inclined double-component glue storage and mixing device 50 is fixedly arranged on the connecting frame 40 and is located beside the valve body 30, the lower end is directly connected to the glue inlet hole 103 in an inclined state, so that the glue flow channel formed between the glue inlet hole 103 and the inner middle part of the hollow dispensing head has a very short stroke, which can be almost ignored, so that the mixed glue flowing in it can be quickly used up each time, so that it is not easy to solidify and block, so that the hollow dispensing head has low replacement frequency, so that the present application has good reliability and long service life.

[0115] And, by setting the glue liquid cooling member A60, even the mixed glue liquid flowing into the inclined glue liquid mixing pipe 503 is cooled and refrigerated, and a low-temperature environment is created to avoid solidification due to high temperature, and since the glue liquid cooling member A60 is openable and wrapped outside the inclined glue liquid mixing pipe 503, when it is opened, the inclined glue liquid mixing pipe 503 and other structural members are easily disassembled, replaced or maintained, so that the application is very convenient to use; by setting the glue liquid cooling member B70, the mixed glue liquid flowing into the hollow glue head combined pipe is cooled and refrigerated, and a low-temperature environment is created to avoid solidification due to high temperature, and since the glue liquid cooling member B70 is openable and wrapped outside the lower part of the hollow glue head, when it is opened, the hollow glue head and other structural members are easily disassembled, replaced or maintained, so that the application is further very convenient to use.

[0116] And the application adopts a double piezoelectric ceramic valve to control the first end and the second end of the lever 310 to swing upward to drive the glue closing plunger 20 to move up and down to correspond to open / close the glue outlet hole 102 of the valve body 30. The double piezoelectric ceramic valve replaces the traditional spring plus single piezoelectric ceramic valve operation mode, which can make the response speed fast and the use precision high.

[0117] Furthermore, by adjusting the pre-tightening force of the first piezoelectric ceramic piece 307 and the second piezoelectric ceramic piece 308 in the up-down direction, the subsequent up-down movement stroke of the first piezoelectric ceramic piece 307 and the second piezoelectric ceramic piece 308 in operation can be controlled, so as to adjust the frequency of the glue closing plunger 20 driven to move up and down, so that the amount of mixed glue liquid discharged from the glue outlet hole 102 each time can be flexibly controlled, making the application more flexible to use.

[0118] Meanwhile, the first adjusting screw 313 and the second adjusting screw 314 are moved in the up-down direction to correspondingly adjust the pre-tightening force of the first piezoelectric ceramic piece 307 and the second piezoelectric ceramic piece 308, so that compared with the traditional horizontal pushing of the top inclined pushing surface of the piezoelectric ceramic valve, the related operation mode of the application is not easy to damage the top of the first piezoelectric ceramic piece 307 and the second piezoelectric ceramic piece 308, and also makes the first piezoelectric ceramic piece 307 and the second piezoelectric ceramic piece 308 have good retention in the vertical direction and are not easy to be tilted due to lateral pushing of the top, so that they have good stability.

[0119] Furthermore, the inclined double-component double-piezoelectric ceramic glue dispensing valve device 1000 provided by the application is extremely practical and has excellent use effect, so that the application will certainly have good market promotion value and will certainly be very popular and will be effectively popularized.
