Description

Technical Field

[0001] The invention relates to the technical field of spray nozzles, and in particular to a ceramic glue coating spray nozzle and a spray gun. Background Art

[0003] The glue spray gun is a device used to spray or inject adhesive onto the surface of the object to be adhered. Existing glue spray guns all control the outflow and stop of the adhesive by cooperating with the valve needle and the copper head glue inlet and other structures inside the glue spray gun under the action of pressure. In the actual operation process, when compressed air or mechanical pressure acts on the spray gun, the valve needle will open, allowing the adhesive to flow out of the glue storage container and be sprayed on the surface of the object to be adhered in the form of mist or line through the nozzle. When the pressure is released, the valve needle is closed to stop the outflow of the adhesive; The spray cores used in existing glue spray nozzles are mostly made of metal. When spraying glue mixed with abrasives, since the abrasives are mixed in the glue, if the viscosity of the glue is low, the abrasives will sink to the bottom, and the glue sprayed up will not meet the required amount of abrasives. Therefore, the viscosity of the glue mixed with abrasives is relatively high, and the existing metal spray cores are severely worn when spraying glue with high viscosity and mixed with abrasives, resulting in the need to frequently replace the spray core during actual use, which not only increases the cost of use but also affects the actual processing efficiency.

[0027] See also Figure 1 The present invention provides a ceramic glue spray nozzle, including a spray core body 101 and a card table 102. The above-mentioned solution solves the problem that the spray cores used in the existing glue spray nozzles are mostly made of metal materials. When spraying glue mixed with abrasives, since the abrasives are mixed in the glue, if the viscosity of the glue is low, the abrasives will sink to the bottom, and the glue sprayed up will not meet the abrasive quantity requirement. Therefore, the viscosity of the glue mixed with abrasives is relatively large, and the existing metal spray cores are severely worn when spraying the glue with high viscosity and mixed with abrasives, resulting in the need to frequently replace the spray cores during actual use, which not only increases the use cost but also affects the actual processing efficiency.

[0028] Furthermore, the clamping platform 102 is fixedly sleeved on the riser body 101, the riser body 101 has a wedge-shaped groove 1011, and the riser body is made of ceramic material.

[0029] Specifically, the riser body 101 is made of ceramic material, which has excellent hardness and corrosion resistance, can withstand long-term wear and chemical erosion, and ensures the long life and stable operation of the equipment; By providing the wedge-shaped groove 1011 inside the nozzle body 101, the design of the glue flow channel is changed, so that the sprayed glue forms a wider and smoother spray pattern, which not only increases the coverage area of ​​the spraying, but also enhances the consistency of the coating thickness, thereby improving the quality of the final product. The ceramic nozzle improved by this solution can be used for one day under normal circumstances, while the existing metal nozzle can only be used for one to two hours.

[0030] Preferably, see Figures 2 to 7 A spray gun adopts the ceramic glue coating nozzle, including a spray gun body 201 and a connecting component, wherein the connecting component includes an access head 202, a mounting frame 203, a conversion bracket 204 and an inserting component, and the inserting component includes an external threaded hole sleeve 205 and an internal threaded sleeve 206.

[0031] Furthermore, the access head 202 is fixedly mounted on the spray gun body 201, the mounting frame 203 is mounted on the access head 202 by bolts, the conversion bracket 204 is connected to the mounting frame 203, and three groups of the inserting components are provided on the conversion bracket 204. The installation between the ceramic glue coating nozzle and the conversion bracket 204 can be completed by the provided inserting components.

[0032] Furthermore, the three externally threaded hole sleeves 205 are fixedly mounted on the conversion bracket 204, and each of the externally threaded hole sleeves 205 is provided with a ceramic glue coating nozzle; the internally threaded sleeves 206 are arranged in a one-to-one correspondence with the externally threaded hole sleeves 205, and the internally threaded sleeves 206 are threadedly connected with the externally threaded hole sleeves 205.

[0033] When the present embodiment is in use, the access head 202 is fixedly arranged at the outer end of the nozzle of the spray gun body 201, and a threaded hole for cooperating with a corresponding bolt and screw is arranged at the bottom of the access head 202, and a slot for cooperating with the access head 202 is arranged at the bottom of the mounting frame 203, and a through hole for cooperating with a corresponding bolt and screw is also arranged at the bottom of the mounting frame 203, so that the user can directly install the mounting frame 203 on the access head 202 by bolts; The adapter bracket is installed on the mounting frame 203, and the connecting cylinder arranged on the back side of the adapter bracket matches the through hole arranged on the mounting frame 203, so that the adapter bracket can be rotated on the corresponding side of the mounting frame 203 and moved a small distance in the corresponding direction. The end of the connecting cylinder of the adapter bracket is provided with a bracket table for installing three ceramic glue coating nozzles, and the three bracket tables are provided with corresponding snap-in ring tables on the back side of the position for installing the ceramic glue coating nozzles, and the bottom of the mounting frame 203 is provided with a corresponding slot for cooperating with the snap-in ring table arranged on the back side of the bracket table; When the ceramic glue spray nozzle cooperates with the insertion through hole inside the external threaded hole sleeve 205, the position can be limited by the set clamping table 102, and then the user can quickly install the ceramic glue spray nozzle by sleeve-installing the internal threaded sleeve 206. By adopting the setting of the adapter bracket, three ceramic glue spray nozzles can be installed at the same time. When one of the ceramic glue spray nozzles is excessively worn due to continuous use, the user can directly replace it with a new ceramic glue spray nozzle by operating the adapter bracket, avoiding the need to spend more time on disassembly and assembly when the ceramic glue spray nozzle needs to be replaced during the processing; The installation between the existing nozzles and the spray guns mostly requires first finding a suitable nozzle, then removing the old nozzle installed on the spray gun, and then installing the new nozzle. The entire replacement process is very inconvenient, especially when long-term continuous processing is required. When a problem suddenly occurs with the nozzle, the time spent on the entire replacement process will directly affect the continuous processing quality of the entire spraying. The conversion bracket 204 set up can prepare two new nozzles in advance. When the corresponding nozzle needs to be replaced, the nozzle can be quickly replaced by operating the conversion bracket 204 to ensure the continuous spraying processing quality.

[0034] Preferably, the connecting assembly provided by the present invention also includes an embedded gasket 301, a snap-in plate 302, a limiting component and a manual control component, the limiting component includes a sliding block 401, a ramp plate 402 and a downward pressure spring 403, the manual control component includes a cone head sleeve 501, a handle 502 and a matching component, and the matching component includes a sliding bracket 503 and a compression spring 504.

[0035] Furthermore, the embedded gasket 301 is installed on the outside of the mounting frame 203; the three snap-in plates 302 are arranged on the side of the conversion bracket 204 close to the mounting frame 203; the limiting member is connected to the mounting frame 203 and is used to limit the conversion bracket 204; the manual control member is connected to the conversion bracket 204 and is used to control the conversion bracket 204 to complete the conversion between ceramic glue coating nozzles.

[0036] When the present embodiment is in use, the embedded gasket 301 is arranged at a position where the mounting frame 203 and the conversion bracket 204 are engaged with the ring stage. The embedded gasket 301 is made of rubber. When the engagement ring stage of the conversion bracket 204 is engaged with the card slot of the mounting frame 203, the surface of the conversion bracket 204 in contact with the outer layer of the mounting frame 203 will squeeze the embedded gasket 301 to deform, thereby ensuring the sealing effect of the connection between the conversion bracket 204 and the mounting frame 203. There are three snap-in plates 302, and the three snap-in plates 302 are installed at a position that matches the position of the conversion bracket 204 for installing three ceramic glue coating nozzles. The mounting frame 203 is provided with a positioning groove for cooperating with the snap-in plates 302, and the outer layer of the positioning groove has a guiding slope, so that when the user rotates the conversion bracket 204 to replace the ceramic glue coating nozzle, the installation position of the ceramic glue coating nozzle can be quickly positioned through the cooperation between the snap-in plate 302 and the positioning groove of the mounting frame 203.

[0037] Furthermore, the sliding block 401 is slidably installed in the mounting frame 203; the inclined platform 402 is slidably installed in the mounting frame 203 and is fixedly connected to the sliding block 401; the two sides of the downward pressure spring 403 are respectively connected to the inclined platform 402 and the mounting frame 203.

[0038] Furthermore, the cone head sleeve 501 is slidably connected to the mounting frame 203 and is located on a side of the mounting frame 203 close to the inclined platform 402; the holding handle 502 is fixedly connected to the cone head sleeve 501; and the mating component is connected to the conversion bracket 204, and is used to connect the conversion bracket 204 and the holding handle 502.

[0039] Furthermore, the sliding bracket 503 is fixedly connected to the holding handle 502 and is slidably mounted on one side of the conversion bracket 204; both sides of the extrusion spring 504 are respectively connected to the sliding bracket 503 and the mounting bracket 203.

[0040] When the present embodiment is in use, the sliding block 401 is used to cooperate with the limiting groove provided on the connecting cylinder on the back side of the conversion bracket 204. There are three limiting grooves, and the limiting angles corresponding to the three limiting grooves are respectively adapted to the matching positions of the three ceramic glue coating nozzles. The top of the sliding block 401 is fixed with the inclined platform 402, and the side of the inclined platform 402 is provided with a corresponding inclined platform. The inclined surface at the end of the cone head sleeve 501 cooperates with the inclined platform provided on the inclined platform 402. The end of the cone head sleeve 501 is fixed The holding handle 502 is provided, and a "U"-shaped platform is provided at the end of the holding handle 502. The user can operate the holding handle 502 to cooperate with the sliding bracket 503 to drive the conversion bracket 204 to rotate. The sliding bracket 503 is slidably connected with the connecting cylinder of the conversion bracket 204. The extrusion spring 504 is provided in the guide groove where the sliding bracket 503 cooperates with the connecting cylinder, and the corresponding downward pressing spring 403 is also provided in the sliding where the inclined platform 402 cooperates with the mounting bracket 203.

When the sliding block moves up to the limit position, the holding handle 502 will continue to slide under the push of the operator, and then squeeze the conversion bracket 204 to move on the mounting frame 203, thereby pulling the locking ring of the conversion bracket 204 out of the slot of the mounting frame 203. After that, the user can drive the entire conversion bracket 204 to rotate by turning the holding handle 502, and then drive the conversion bracket 204 to rotate. After the bracket 204 rotates about one hundred and twenty degrees, the user can pull the handle 502 to allow the rotating and repositioned snap-in ring on the conversion bracket 204 to cooperate with the slot of the mounting frame 203 to complete the replacement of the corresponding ceramic glue coating nozzle on the conversion bracket. When the handle 502 pulls the conversion bracket 204 to install the converted ceramic glue coating nozzle, since the inclined table 402 loses the support limit of the cone head sleeve 501, the inclined table 402 will drive the sliding block 401 to cooperate with the limit slot of the cylindrical connection on the back side of the conversion bracket 204 under the action of the downward pressure spring 403, thereby ensuring the stability of the cooperation position of the conversion bracket 204 and realizing the rapid replacement and installation of the ceramic glue coating nozzle.
