Description

Technical Field

[0001] The utility model relates to the technical field of dispensing equipment, in particular to a spray valve device with a refrigeration function. Background Art

[0002] A dispensing valve is an essential dispensing accessory in dispensing equipment for product dispensing, glue coating, potting, encapsulation, etc. Its main functions are to transport the encapsulated glue medium and quickly suck back and stop the glue flow in case of dripping of the colloid or fluid during the encapsulation process to ensure the encapsulation quality.

[0003] Briefly speaking, a dispensing valve is a special switch that can achieve instant glue stop and is often used together with a dispenser and a potting machine. Commonly used ones include a volume valve, a back suction type dispensing valve, a thimble type dispensing valve, a plunger type dispensing valve, a jet type dispensing valve, etc.

[0004] For the common jet type dispensing valve in the prior art, especially the spray valve used, it can spray the glue liquid downward onto the product surface in an atomized state to achieve spray type dispensing. However, for most glue liquids, there are certain requirements for their usage states. For example, the ambient temperature is required to be maintained at about 15 degrees to reduce its activity, thereby reducing its curing speed and preventing wire drawing during the dispensing process. But especially in summer when the ambient temperature is required to be maintained at about 15 degrees, air conditioning needs to be turned on for cooling. When the air conditioner breaks down or does not refrigerate, etc., it cannot continue to be used in a low-temperature environment of about 15 degrees. In this way, its use has certain limitations and poor adaptability.

[0005] In response to this, the inventor of this patent, combining work experience, through in-depth thinking about the problems encountered in work, consulting a large number of scientific research materials and literature, and through retrieval and novelty search, gradually conceived and designed this application to solve the related technical problems.

[0030] The beneficial effects of the utility model are:

[0067] The spray valve device 1000 with a refrigeration function according to an embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

[0068] Refer to Figures 1 to 5As shown in the figure, the spray valve device 1000 with a refrigeration function provided by an embodiment of the present utility model includes a glue bucket 10 for containing glue, a glue shut-off plunger 20, and a piezoelectric valve 30 for driving the glue shut-off plunger 20 to move up and down; the improvement of the present utility model lies in that it further includes a glue guiding plate 40, a glue atomizing nozzle 50, and a glue cooling member A 60;

[0069] Wherein, the glue guiding plate 40 has a through groove 401 opened in the up and down direction through its upper and lower end faces, and has a glue guiding flow channel 402 opened in the horizontal or oblique direction inside and communicating with the through groove 401. The upper end face of the glue guiding plate 40 is provided with a glue inlet 403 communicating with the glue inlet end of the glue guiding flow channel 402, and the glue inlet 403 is communicated with the bottom of the glue bucket 10;

[0070] And, the glue atomizing nozzle 50 is arranged below the glue guiding plate 40, and its upper end is communicated with the bottom of the through groove 401; the upper end of the glue shut-off plunger 20 is connected to the piezoelectric valve 30, and the lower end passes through the through groove 401 and is inserted into the glue atomizing nozzle 50 to move up and down under the control of the piezoelectric valve 30 to correspondingly open / close the glue atomizing nozzle 50;

[0071] And the glue cooling member A 60 is sleeved and fixed outside the lower end of the glue bucket 10 to cool the fluid glue contained in the glue bucket 10.

[0072] Based on the above, it can be clear that when the present application is specifically implemented, it is mainly used as a spray valve device 1000 with a refrigeration function.

[0073] Specifically, when applying the present application, the glue to be used is installed in the glue bucket 10, and the installed glue can enter the glue guiding flow channel 402. When the piezoelectric valve 30 drives the glue shut-off plunger 20 to move upward to open the glue atomizing nozzle 50, the glue can enter the glue atomizing nozzle 50 through the glue guiding flow channel 402 and exit the glue in an atomized manner from the lower end of the glue atomizing nozzle 50.

[0074] On the contrary, when the piezoelectric valve 30 drives the glue shut-off plunger 20 to move downward to close the glue atomizing nozzle 50, the glue can be blocked so that it does not enter the glue atomizing nozzle 50. At this time, the use of the present application can be stopped.

[0075] It should be noted here that the principle of the above-mentioned piezoelectric valve 30 driving the glue needle 20 to move up and down to open / close the glue atomizing nozzle 50 is exactly the same as the principle of the utility model patent "Atomizing Glue Dispensing Equipment" with patent number "202123387351.7" previously applied by the applicant of this patent, which drives the glue needle 20 to move up and down through the upper and lower driving components to open / close the glue dispensing valve. Therefore, the specific operating details will not be described in detail here.

[0076] The use of this application will obviously have the following technical effects:

[0077] On the one hand, since the present application is provided with the glue cooling component A60, which is fixedly sleeved on the outside of the lower end of the glue barrel 10, the fluid glue installed in the glue barrel 10 can be cooled, so that the fluid glue installed in the glue barrel 10 can be kept at a low temperature as much as possible, thereby reducing its curing speed and preventing wire drawing during the dispensing process. Especially in summer when the ambient temperature is required to be maintained at around 15 degrees, the present application comes with the glue cooling component A60 for cooling, so that there is no need to rely on air conditioning. In this way, the present application is not limited to high temperature environments and has strong adaptability.

[0078] On the other hand, the fluid glue installed in the glue barrel 10 can be kept at a low temperature as much as possible, so that it is not easy to solidify and deposit. When it flows into the glue atomizing nozzle 50, it is not easy to block the glue atomizing nozzle 50 due to solidification and deposition, so that the service life of the glue atomizing nozzle 50 is long, and the frequency of replacement and maintenance can be greatly reduced, thereby greatly reducing the replacement cost and manual disassembly and assembly cost of the glue atomizing nozzle 50.

[0079] Therefore, through the above-mentioned optimized design, the whole formed by the present application is highly practical and has good use effect.

[0080] On this basis, in this technical solution, Figure 5 As shown, according to one embodiment of the utility model, it also includes a sealing ring A70;

[0081] The rubber guide plate 40 is provided with a clamping groove at the upper end of the through groove 401 , and the sealing ring A70 is clamped in the clamping groove and is fixedly sleeved outside the rubber closing striker 20 and does not move up and down with the rubber closing striker 20 .

[0082] Therefore, by setting the sealing ring A70, the upper part of the through groove 401 can be better sealed, so that when the glue-closing striker 20 moves up and down along the through groove 401, it is not easy to bring the glue liquid upward to the outside of the upper part of the through groove 401, making the application reliable to use.

[0083] And on this basis, in the present technical solution, in comparison Figure 2 and Figure 4 As shown, according to an embodiment of the present utility model, the glue liquid cooling member A60 includes a heat-conducting sleeve A601, a refrigeration sheet A602, and a cooling water tank A603;

[0084] Among them, the heat-conducting sleeve A601 is fixedly sleeved outside the lower end of the glue bucket 10, and a fitting surface A6011 is formed by cutting on its outer wall; the refrigeration sheet A602 is clamped between the fitting surface A6011 and the outer wall of the cooling water tank A603; the cooling water tank A603 is provided with a liquid inlet hole A6031 and a liquid discharge hole A6032.

[0085] In this regard, it can be clearly understood that the main working principle of the glue liquid cooling member A60 described in the present application is generally as follows:

[0086] First, install the present application according to the above-described structure. Subsequently, when using the present application, the refrigeration sheet A602 is powered on. The heat of the fluid glue installed in the glue bucket 10 will be conducted outward by the heat-conducting sleeve A601, and the conducted heat will be absorbed by the inner end surface of the powered-on refrigeration sheet A602. The outer end surface of the refrigeration sheet A602 will synchronously dissipate heat and conduct the heat to the cooling water tank A603. When the cooling water in the cooling water tank A603 circulates in and out through the liquid inlet hole A6031 and the liquid discharge hole A6032, it can further conduct the heat outward, so that the heat of the fluid glue installed in the glue bucket 10 will be almost completely absorbed, so that it will flow out downward in a low-temperature state.

[0087] In this way, it is ensured that the glue liquid cooling member A60 described in the present application indeed has a good function of cooling the fluid glue installed in the glue bucket 10.

[0088] Furthermore, in specific implementation, continue to compare Figure 2 and Figure 4 As shown, according to an embodiment of the present utility model, the glue liquid cooling member A60 further includes a heat-insulating sleeve A604 and an anti-condensation blowing valve A605 adapted to be externally connected to a blowing device;

[0089] Among them, the heat-insulating sleeve A604 is fixedly sleeved outside the heat-conducting sleeve A601; an air duct A is opened inside the heat-conducting sleeve A601, a blowing hole A communicating with the air duct A is opened on the fitting surface A6011, and the anti-condensation blowing valve A605 is arranged outside the heat-insulating sleeve A604 and is connected to the blowing hole A through the heat-insulating sleeve A604.

[0090] In this regard, it can be understood that:

[0091] On the one hand, when the glue liquid cooling member A60 further includes the heat insulation sleeve A604, it can better enclose the heat conduction sleeve A601, so that the heat conduction sleeve A601 is isolated from the external air, enabling it to conduct heat to the fluid glue installed in the glue bucket 10 as much as possible, making the cooling effect of the glue liquid cooling member A60 on the fluid glue installed in the glue bucket 10 better.

[0092] On the other hand, when an external blowing device is connected to the anti-condensation blowing valve A605, external gas can be blown into the air duct A (not shown) through the blowing holes A, so as to prevent water vapor in the air from pre-cooling and condensing into water droplets on the surface of the heat conduction sleeve A601 and dripping onto the surface of the product to be dispensed, which may damage the product to be dispensed.

[0093] Furthermore, through the above optimization design, the overall use effect of the present application can be effectively improved.

[0094] Preferably, in the present technical solution, according to an embodiment of the present invention, the anti-condensation blowing valve A605 and the air outlet A connected thereto are both located below the joint surface A6011, and an exhaust hole A6012 communicating with the air duct A inside is opened at the top of the heat conduction sleeve A601.

[0095] In this way, even when a small amount of water droplets are condensed on the surface of the heat conduction sleeve A601, the generated water droplets will be blown upward and dried, and the blown gas will also be discharged upward through the exhaust hole A6012 instead of being blown onto the surface of the product to be dispensed, which may damage the product to be dispensed, making the use reliability of the present application good.

[0096] Furthermore, during specific implementation, still referring to Figure 2 and Figure 4 shown, according to an embodiment of the present invention, it further includes a glue liquid cooling member B80;

[0097] Among them, the glue liquid cooling member B80 is laminated and fixed on the lower bottom surface of the glue guiding plate 40 and encloses the upper part of the glue liquid atomizing nozzle 50.

[0098] Thus, by setting the glue liquid cooling member B80 and enclosing and fixing it on the upper part of the glue liquid atomizing nozzle 50, it can cool the fluid glue flowing or remaining in the glue liquid atomizing nozzle 50, so that its temperature is also lower than normal temperature, making it difficult for the fluid glue flowing or remaining in the glue liquid atomizing nozzle 50 to solidify and deposit, and it is not easy for the inside of the glue liquid atomizing nozzle 50 to be blocked by the solidified glue liquid, making the overall structure of the present application have a longer service life and better use reliability.

[0099] Preferably, in the present technical solution, it is still in comparison with Figure 2 and Figure 4 As shown, according to an embodiment of the present invention, the glue liquid cooling member B80 includes a heat conducting plate B801, a refrigeration sheet B802 and a cooling water tank B803;

[0100] Wherein, the heat conducting plate B801 is laminated and fixed on the lower bottom surface of the glue guiding plate 40, and a fitting surface B8011 is formed by cutting at the bottom thereof; the refrigeration sheet B802 is clamped between the fitting surface B8011 and the upper end surface of the cooling water tank B803; the cooling water tank B803 is provided with a liquid inlet hole B8031 and a liquid discharge hole B8032;

[0101] In this regard, it can be clearly understood that the main working principle of the glue liquid cooling member B80 described in the present application is generally as follows:

[0102] First of all, install the present application according to the above structure. Subsequently, when using the present application, the refrigeration sheet B802 is powered on. The heat of the fluid glue flowing or remaining in the glue liquid atomizing nozzle 50 will be absorbed by the heat conducting plate B801 and conducted downward. The conducted heat will be absorbed by the upper end surface of the powered-on refrigeration sheet B802. The lower bottom surface of the refrigeration sheet B802 will synchronously dissipate heat and conduct the heat to the cooling water tank B803. When the cooling water in the cooling water tank B803 circulates in and out through the liquid inlet hole B8031 and the liquid discharge hole B8032, the heat can be further conducted outward, so that the heat of the fluid glue flowing or remaining in the glue liquid atomizing nozzle 50 will be almost completely absorbed, so that it will flow out downward in a low temperature state.

[0103] Therefore, the glue liquid cooling member B80 described in the present application does have a very good function of cooling the fluid glue flowing or remaining in the glue liquid atomizing nozzle 50.

[0104] Furthermore, in specific implementation, in comparison with Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, according to an embodiment of the present invention, the glue liquid atomizing nozzle 50 includes a glue guiding pipe 501 and an air sleeve 502 wrapped outside the glue guiding pipe 501;

[0105] Wherein, a hollow connector 404 communicating with the through groove 401 is provided downward on the lower bottom surface of the glue guiding plate 40 directly below the through groove 401; the upper end of the glue guiding pipe 501 and the upper end of the air sleeve 502 are both inserted and connected to the hollow connector 404; there is a certain gap A between the inner wall of the air sleeve 502 and the outer wall of the glue guiding pipe 501 to form an air flow channel A503;

[0106] Moreover, the lower end of the glue guiding tube 501 is formed into a reduced opening A5011 for downwardly discharging the glue liquid; the lower end of the air sleeve 502 is formed into a reduced opening B5021 for downwardly discharging the gas, and the reduced opening B5021 is located outside the reduced opening A5011 and is flush with the reduced opening A5011.

[0107] And the lower end of the glue closing plunger 20 is inserted into the glue guiding tube 501 through the hollow connector 404 and can move downward under the control of the piezoelectric valve 30 to block the reduced opening A5011.

[0108] Thus, it can be clearly understood that the working principle of the glue liquid atomizing nozzle 50 of the present application is generally as follows:

[0109] The fluid glue installed in the glue bucket 10 enters the glue guiding tube 501 through the glue guiding channel 402 in the glue guiding plate 40 and slowly flows downward from the reduced opening A5011. Synchronously, gas is squeezed into the air flow channel A503, and the squeezed gas flows downward and is squeezed out from the reduced opening B5021. At this time, the outflowing gas will be mixed with the outflowing fluid glue to finally form spray-shaped glue liquid particles and spray downward.

[0110] In this way, the atomized spraying of the glue liquid on the surface of the product to be glued is realized by using the present application for glue dispensing.

[0111] In addition, in this technical solution, according to an embodiment of the present invention, a through hole 8012 that penetrates the upper and lower end faces of the heat conducting plate B801 and fits and encloses the upper end of the air sleeve 502 is opened on the heat conducting plate B801, and a collar 8013 that fits and encloses the middle part of the air sleeve 502 extends downward at the lower part of the through hole 8012. There is a certain gap B between the inner wall of the collar 8013 and the outer wall of the air sleeve 502 to form an air flow channel B8014.

[0112] On this basis, continue to compare Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, a gas guiding channel 8015 communicating with the air flow channel B8014 is opened inside the heat conducting plate B801 of the present application; an air inlet connector 8016 communicating with the gas guiding channel 8015 is provided outside the heat conducting plate B801; a plurality of air guiding holes 5022 are uniformly opened in the middle and upper part of the outer wall of the air sleeve 502 to connect the lower part of the air flow channel B8014 with the upper part of the air flow channel A503.

[0113] Thus, by externally connecting a gas supply device through the intake connector 8016, the supplied gas will enter the air flow path B8014 through the air guide flow path 8015, and then enter the air guide flow path 8015A through a plurality of the air guide holes 5022, so as to finally flow out through the constriction B5021.

[0114] For the above application of the present application, through optimized design, when the gas entering the air flow path B8014 enters the air guide flow path 8015A through a plurality of the air guide holes 5022 provided in a ring shape, it can flow uniformly downward from the air guide flow path 8015A, and finally flow out uniformly from the inner periphery of the constriction B5021, so as to achieve uniform mixing with the fluid glue flowing out from the constriction A5011 in the circumferential direction, so that the finally formed spray-like glue particles can be uniformly sprayed downward to a preset glue application position on the surface of the product to be glue applied, so that the glue application uniformity of the preset glue application position on the surface of the product to be glue applied is good and the glue layer thickness at each position can be kept as consistent as possible.

[0115] Furthermore, in specific implementation, still referring to Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, according to an embodiment of the present invention, a seal ring B90 located above a plurality of the air guide holes 5022 is fixedly provided between the upper end of the outer wall of the air sleeve 502 and the inner wall of the through port 8012; a seal ring C100 located below a plurality of the air guide holes 5022 is fixedly provided between the middle of the outer wall of the air sleeve 502 and the lower part of the inner wall of the collar 8013.

[0116] Thus, by providing the seal ring B90 and the seal ring C100, the upper and lower ends of the air flow path A503 can be better sealed, and the gas leakage prevention effect is good.

[0117] It should be added that in specific implementation, referring to Figure 1 and Figure 3 shown, according to the spray valve device 1000 with a refrigeration function provided by an embodiment of the present invention, the present application further includes a fixing bracket 110 for fixing the glue cooling member A60;

[0118] Wherein, the fixing bracket 110 is fixedly provided on the piezoelectric valve 30, and a fixing clamp 1101 for clamping the glue cooling member A60 is provided thereon.

[0119] In this regard, by providing the fixing bracket 110, the fixing of the glue cooling member A60 outside the glue bucket 10 is further strengthened, so that it is not easy to loosen and shift, and thus the stability in use is good.

[0120] At the same time, in the specific implementation, the glue guiding channel 402 opened in the glue guiding plate 40 is preferably arranged obliquely so that the height of the glue feeding end is higher than the height of the glue discharging end, and the glue discharging end is connected to the through groove 401. The glue feeding end is also provided with a maintenance port along its length direction, and a detachable sealing plug 405 is inserted in the maintenance port. In this way, when the sealing plug 405 is unscrewed, it is easy to discharge the fluid glue remaining in the glue guiding channel 402, or to insert a tool to scrape off the solidified glue remaining in the glue guiding channel 402, so that the maintenance of the present application is convenient, so as to extend the service life of the present application.

[0121] Other embodiments and the like are not described here by way of example.

[0122] In summary, the spray valve device 1000 with refrigeration function provided by the present application, during specific implementation, since the present application is provided with the glue cooling component A60, which is sleeved outside the lower end of the glue barrel 10, the fluid glue installed in the glue barrel 10 can be cooled, so that the fluid glue installed in the glue barrel 10 can be kept at a low temperature as much as possible, thereby reducing its curing speed and preventing wire drawing during the dispensing process. Especially in summer when the ambient temperature is required to be maintained at about 15 degrees, the present application comes with the glue cooling component A60 for cooling, so that there is no need to rely on air conditioning. In this way, the use of the present application is not limited to high temperature environments, and it has strong adaptability.

[0123] Furthermore, the fluid glue contained in the glue barrel 10 can be kept at a low temperature as much as possible, so that it is not easy to solidify and deposit. When it flows into the glue atomizing nozzle 50, it is not easy to clog the glue atomizing nozzle 50 due to solidification and deposition, so that the service life of the glue atomizing nozzle 50 is long, and the replacement and maintenance frequency can be greatly reduced, thereby greatly reducing the replacement cost and manual disassembly and assembly cost of the glue atomizing nozzle 50.

[0124] Furthermore, by providing the glue cooling component B80, when it is enclosed and fixed on the upper part of the glue atomizing nozzle 50, the fluid glue flowing or remaining in the glue atomizing nozzle 50 can be cooled so that its temperature is lower than normal temperature, so that the fluid glue flowing or remaining in the glue atomizing nozzle 50 is not easy to solidify and deposit, so that the inside of the glue atomizing nozzle 50 is not easy to be blocked by the solidified glue, so that the whole formed by the present application has a longer service life and better reliability in use.

[0125] In addition, when the gas entering the air flow channel B8014 enters the air guiding flow channel 8015A through the multiple air guiding holes 5022 arranged in a ring, it can flow uniformly downward from the air guiding flow channel 8015A and finally flow out uniformly from the inner periphery of the reduced diameter opening B5021, so as to achieve uniform mixing with the fluid glue flowing out from the reduced diameter opening A5011 in the circumferential direction, so that the finally formed spray-like glue particles can be uniformly sprayed downward to the preset glue dispensing position on the surface of the product to be glue dispensed, so that the glue dispensing uniformity of the preset glue dispensing position on the surface of the product to be glue dispensed is good and the glue layer thickness at each position can be kept as consistent as possible.

[0126] Furthermore, the spray valve device 1000 with a refrigeration function provided by the present application is indeed extremely practical and has excellent use effects, so that the present application will surely have good market promotion value, the present application will surely be very popular and will surely be effectively popularized.
