Description

Technical Field

[0001] This utility model relates to the field of adhesive spraying valve technology, and in particular to a high-speed spraying valve structure assembly. Background Technology

[0002] The high-speed spray valve is a device specifically designed for efficient and precise adhesive spraying operations, suitable for automated production environments requiring high frequency, small dosage, and rapid response. It is widely used in various industries such as garment manufacturing, electronics assembly, packaging, and automotive manufacturing. Particularly in garment adhesive spraying, it is used for bonding fabrics and fixing decorative parts. This device can perform precise dispensing or linear spraying at a frequency of dozens of times per second, ensuring consistent adhesive volume and accurate positioning each time. It can adapt to different types of adhesive spraying needs, including but not limited to dot spraying, line spraying, and atomized spraying, meeting the requirements of diverse production processes.

[0003] The existing Chinese patent with publication number CN110496722B discloses a non-contact multi-channel high-speed jet valve, which can effectively solve the problem of the current screen printing production mode in the clothing fabric, shoe material, and bag fabric industries, which uses templates as references, is inefficient, and causes environmental pollution and energy waste due to manual hand-held drawing. The technical solution is as follows: This high-speed jet valve is composed of an actuator, a flow channel assembly, an ink and solvent container assembly, and a high-frequency solenoid valve drive mechanism. The side of the high-speed jet valve actuator is tightly connected to the high-frequency solenoid valve drive mechanism by a sealing pipe thread joint. Compressed air through the solenoid valve drive mechanism drives the piston rod inside the high-speed jet valve actuator to move upward. Under the reaction force of the double high-strength compression springs, the piston rod quickly resets and moves downward, impacting the ink in the lower nozzle and ejecting it from the small hole to achieve non-contact ink jetting.

[0004] Although this patent falls under the same field of garment adhesive spraying, it does not disclose the specific structure of the adhesive spraying channel. The nozzle plays a crucial role in adhesive spraying, and this prior art only explains the general principle. However, when applied to specific spraying environments, such as achieving adhesive-breaking effects, it fails to explain the adhesive-breaking effect and its underlying principles. Furthermore, the disclosed adhesive spraying method uses traditional compressed air without improving the compressed air temperature or adding any related structures to coordinate with air temperature improvement. Different gas temperatures during the spraying process can lead to different adhesive-breaking or anti-coagulation effects. Therefore, the inventor proposes a high-speed spray valve assembly that incorporates adhesive-breaking technology, improves the adhesive spraying channel within the valve body, and enhances the air temperature for the auxiliary spraying process to solve the aforementioned technical problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems. A high-speed spray valve assembly includes a mounting base, an air chamber, a fixing ring, a pipe structure, and a valve structure. The valve structure includes an inlet pipe, an inlet storage section, a drive motor, and a valve body. One end of the inlet pipe abuts against the inlet storage section, and one end of the inlet storage section abuts against the valve body. A protective shell is provided between the inlet storage section and the valve body. One end of the inlet storage section is connected to an adjusting handle for controlling the amount of adhesive dispensed. The adjusting handle functions as an adjusting valve for dispensing adhesive. One end of the valve body is a connector, and one end of the connector abuts against one end of the inlet storage section. The end of the valve body away from the connector is the valve port. The valve body has an internal flow channel structure for assisting in dispensing adhesive and air. This high-speed spray valve is used for adhesive spraying in clothing, and its internal flow channel structure differs from that used in the painting industry. The retaining ring is fixed to the surface of the mounting base. The retaining ring is used to limit the position of the air chamber. The pipeline structure includes a cold air heating pipe, a cold air section and a hot air passage. One end of the cold air heating pipe is connected to the air chamber. The cold air section is located at the end of the cold air heating pipe connected to the air chamber. The hot air passage is located at the end of the cold air heating pipe near the valve port. The cold air heating pipe is equipped with a heating component inside. The key design feature of this structure lies in the coordination between the overall structure and its components. The air chamber is installed using mounting bases and fixing rings, and the air chamber provides an air source that allows air to enter the piping structure. Then, depending on the usage scenario, cold or hot air can be selectively used in conjunction with the valve structure for the glue spraying process. While improving the valve structure, the operating principle between the overall structure and the valve structure is also provided. On this basis, a piping structure and heating components are added, allowing operators to selectively use different types of cold or hot air for the glue spraying process. Cold air can increase the glue's solidification speed, suitable for small-volume or short-duration glue spraying, facilitating the subsequent cleaning process. Hot air can slow down the glue's solidification speed, suitable for long-duration glue spraying and batch production. The combination of the two allows switching between long and short-duration glue spraying processes, further increasing the versatility and flexibility of operation. Furthermore, the flow channel structure includes an adhesive flow channel, an air flow channel, and an adhesive outlet. The adhesive flow channel is in communication with the interior of the adhesive storage section, and the opening at one end of the adhesive flow channel is in communication with the interior of the adhesive outlet. The adhesive flow channel is directly connected to the adhesive storage section and leads to the adhesive outlet, forming a continuous, dead-angle-free, low-resistance adhesive delivery channel. This structure helps reduce the flow path of the adhesive from the storage section to the outlet, while also reducing shear resistance and pressure loss during the flow process. This facilitates rapid response, allowing the adhesive to be sprayed out the instant the valve is opened, meeting the needs of high-speed spraying. At the same time, it avoids the accumulation of adhesive in the adhesive flow channel, which would otherwise cause the adhesive to solidify into lumps within the channel. Furthermore, both the airflow channel and the adhesive flow channel are inclined, and a baffle ring area is provided on the surface of the valve body to reduce gas leakage. The baffle ring area is located in the annular area between the adhesive outlet and the valve body. The opening at one end of the airflow channel penetrates the surface of the valve body and communicates with the baffle ring area. By adopting an inclined design for both the airflow channel and the adhesive channel, the fluid dynamics performance is optimized, flow interference is reduced, and the formation of head-on collisions or vortices between the gas and adhesive phases in the intersection area is avoided. The airflow is introduced along the inclined direction, which can more smoothly wrap or push the adhesive, achieving efficient air-assisted adhesive dispensing, reducing turbulence and pressure fluctuations, improving spraying stability, preventing adhesive spraying vibration or deviation, and preventing stringing. When the inclined airflow impacts the root of the flowing adhesive column from the side or above, the inclined airflow can generate shear force to quickly cut the adhesive line, reducing obvious stringing and achieving an effective adhesive breaking effect, thus avoiding adhesive string contamination of the fabric. The retaining ring area is a ring-shaped groove structure around the glue outlet, forming a physical barrier. When compressed air enters the retaining ring area from the airflow channel, it is confined within the ring space and cannot diffuse freely in all directions. The gas can only act in the direction of the glue outlet, significantly reducing gas waste and leakage noise, improving air energy utilization efficiency, and causing the airflow to converge here to form a "ring-shaped air curtain". When the glue spraying is finished, the compressed air forms a ring-shaped airflow in the retaining ring area, blowing out the trace amount of glue residue left at the edge of the glue outlet, preventing glue accumulation and hardening, and keeping the nozzle clean. Furthermore, the flow channel structure includes hot air jet holes and glue outlet holes. The hot air jet holes are distributed in a ring at one end of the valve body and penetrate the surface of the valve body. The spacing between two adjacent air jet holes is equidistant. The air jet holes have an inclined structure, and the inclined direction of the air jet holes is towards the glue outlet holes. The glue outlet holes are respectively connected to the interior of the glue storage part and the valve port. Hot air nozzles are arranged in a ring at one end of the valve body and tilted towards the glue outlet. This allows the hot air to directly act on the sprayed glue during the spraying process. The hot air rapidly heats and solidifies the glue, enhancing its coagulation properties and improving the spraying effect. It also improves the glue's diffusion and adhesion, ensuring a more uniform and refined spraying result. Because the hot air accelerates the drying speed of the glue surface, it reduces waiting time in subsequent processes and improves overall production efficiency. The air nozzles are equidistant and tilted, with the tilt direction all converging towards the glue outlet, ensuring that the hot air evenly surrounds the glue outlet. When the tilted airflow impacts the root of the flowing glue column from the side or above, the tilted airflow can generate shear force, quickly cutting the glue line and reducing obvious stringing. This effectively breaks the glue and prevents glue strands from contaminating the fabric. In garment spraying, this glue-breaking effect increases the aesthetics of the fabric during bonding and avoids glue solidification lumps caused by ineffective glue breaking, which can lead to localized protrusions during fabric bonding. Furthermore, the drive motor is mounted on the surface of the protective housing, the output end of the drive motor is connected to the flow channel structure, and one end of the drive motor is electrically connected to a power connection line for connecting to an external power source. The drive motor is positioned externally on the protective housing surface, rather than embedded within it, allowing for easy installation and independent structure. Disassembly and assembly do not require disassembly of the valve body or the entire structure, making maintenance and replacement more convenient, facilitating rapid on-site repairs, reducing equipment downtime, and improving production continuity. Furthermore, the drive motor is in contact with external air but is isolated from the adhesive circuit or hot air passage, preventing heat buildup inside the valve body and extending its lifespan. The drive motor is an air pump motor; when connected to an external power source via a power cable, it generates driving force to propel the gas into the outlet flow channel, facilitating the spraying and cutting of the adhesive. Furthermore, the surface of the connector is provided with mounting holes and connection holes for assisting in the installation of the connector. Both mounting holes and connection holes are used to connect external screws. By passing the external screws through the mounting holes and connection holes and locking them, the valve can be quickly installed in the designated position, which is suitable for batch assembly and equipment integration. The symmetrically arranged mounting holes and connection holes in this structure can ensure that the spatial position and angle of the valve in the equipment are accurately fixed, avoiding glue spraying deviation and ensuring the consistency of the glue spraying trajectory. In high-speed automated production lines, there may be vibration. The mounting holes and connection holes, together with the screws, can effectively prevent the valve from loosening or shifting, improving operational stability. The standardized layout facilitates the quick replacement and universal adaptation of the valve, and is suitable for different models of glue spraying equipment. Furthermore, the valve body and valve port are detachable; the detachable design allows technicians to easily remove the valve port for internal cleaning or replacement. Replacement can remove residual glue or other impurities from the valve port, preventing blockage caused by long-term accumulation. When the valve port component is worn, damaged, or needs upgrading, this component can be replaced individually without replacing the entire valve body, reducing maintenance costs. Furthermore, the heating assembly includes one of a heating wire, an electric heating block, or an electric heating base; The heating component is located inside the cold air heating pipe. Its core function is to heat the cold air from the air chamber, which helps to slow down the curing of the adhesive. At the same time, the heated gas is affected by the pressure, which can also increase the jet speed of the airflow and play a role in cutting off the adhesive. The heating wire is lightweight and has a small heat capacity, allowing it to heat up rapidly after being energized, achieving instant heating and meeting the rapid response requirements of high-speed spraying for airflow temperature. The electric heating block is large in size, has a high heat capacity, and exhibits small temperature fluctuations, providing an extremely stable heat source, which is beneficial for maintaining the consistency of the adhesive spraying process. The heating function of the electric heating base is integrated into the fixed base of the valve or pipeline, simplifying the overall structure and reducing the installation of independent heating components. This structure can be installed according to actual needs. Furthermore, an insulation block is provided between the mounting base and the cold air heating pipe to slow down the air cooling, a hot air diversion port is provided in the hot air channel to assist the flow channel structure in air diversion, and a glue switch control rod for adjusting the glue dispensing amount is provided inside the valve body. The insulation block is made of ceramic, high-temperature resistant plastic, and aluminum silicate fiber, ensuring the stability of hot air temperature. This ensures that the temperature of the airflow entering the hot air channel and the airflow used for final adhesive spraying is high and stable enough, avoiding the decrease in airflow energy due to mid-process cooling, which would affect the adhesive spraying speed and atomization effect. It also reduces the additional heating power required to compensate for heat loss, thus reducing energy consumption. The hot air diversion port is used to cooperate with the hot air spray hole to allow hot air to be sprayed out of the designated channel, thereby assisting in the completion of the process. The air chamber contains dry ice, which is solid carbon dioxide. When it sublimates, it absorbs a large amount of heat. It can be selectively placed in the air chamber to rapidly and significantly reduce the temperature of the compressed air entering the chamber or the air inside the chamber. This provides a stable and sufficiently low initial temperature for the subsequent cold air section. When the heating components are not running, cold air is supplied through the air chamber and the cold air section. The cold air accelerates the complete curing of residual adhesive and makes it brittle. When the adhesive is sprayed again, the high-speed hot air or adhesive switch control lever can easily blow away or shake off these brittle adhesive residues, thereby effectively preventing blockage and facilitating the process. Compared with the prior art, the beneficial effects of this utility model are: 1. Optimize fluid dynamics performance and reduce flow interference. This can prevent the gas and adhesive phases from forming head-on collisions or vortices in the intersection area. The airflow is introduced along the inclined direction, which can more smoothly wrap or push the adhesive, achieve efficient gas-assisted dispensing, reduce turbulence and pressure fluctuations, improve spraying stability, prevent spraying vibration or deviation, and prevent stringing. 2. Using hot air allows it to act directly on the sprayed adhesive during the spraying process. Hot air can quickly heat and solidify the adhesive, enhancing its coagulation properties, thereby improving the spraying effect, increasing the adhesive's diffusion and adhesion, ensuring a more uniform and finer spraying effect, and because hot air accelerates the drying speed of the adhesive surface, it reduces the waiting time in subsequent processes and improves overall production efficiency. 3. The installation and fixation are carried out by coordinating the overall structure and components. An air source is provided through an air chamber to allow air to enter the pipeline structure. Then, depending on the usage scenario, cold air or hot air is selectively used in conjunction with the valve structure to carry out the glue spraying process. While improving the valve structure, a pipeline structure and heating components are added on this basis, so that operators can selectively use different cold air or hot air for the glue spraying process, further increasing the diversity and flexibility of operation. 4. Using dry ice or heating components further enhances the performance of cold or hot air, which can embrittle adhesive residue or accelerate the air to break the adhesive through the pressure generated by heat, while also preventing the adhesive from solidifying, thus enabling the continuous application of adhesive.

Detailed Implementation

[0007] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0008] Example 1: Please see Figures 1-9 , Figures 12-16 The present invention relates to a high-speed spray valve assembly, comprising a mounting base 17, an air chamber 18, a fixing ring 19, a piping structure, and a valve structure. The valve structure includes an inlet pipe 1, an inlet storage section 2, a drive motor 3, and a valve body 4. One end of the inlet pipe 1 abuts against the inlet storage section 2, and one end of the inlet storage section 2 abuts against the valve body 4. A protective outer shell 5 is provided between the inlet storage section 2 and the valve body 4. One end of the inlet storage section 2 is connected to an adjusting handle 26 for controlling the amount of adhesive dispensed. The adjusting handle 26 functions as an adjusting valve for dispensing adhesive. One end of the valve body 4 is a connector 6, one end of which abuts against one end of the inlet storage section 2. The end of the valve body 4 away from the connector 6 is a valve port 7. The valve body 4 has an internal flow channel structure for assisting in adhesive and air dispensing. This high-speed spray valve is used for adhesive spraying in clothing, and its internal flow channel structure differs from that used in the painting industry. By employing high-speed spray valve technology, fast and precise glue spraying can be achieved, accelerating the production line and reducing the time of each work cycle. The valve structure controls the amount of glue sprayed and the amount of air emitted, ensuring that the amount of glue used is appropriate, avoiding waste and ensuring the consistency of bonding quality. At the same time, under the blowing force of high-speed gas, the glue is sprayed out in a ring structure, increasing the bonding area. Meanwhile, the texture formed by the gas when the glue is sprayed out helps the fabric to bond, thus increasing the bonding strength. The retaining ring 19 is fixed to the surface of the mounting base 17. The retaining ring 19 is used to limit the position of the air chamber 18. The pipeline structure includes a cold air heating pipe 20, a cold air section 21 and a hot air channel 22. One end of the cold air heating pipe 20 is connected to the air chamber 18. The cold air section 21 is located at the end of the cold air heating pipe 20 connected to the air chamber 18. The hot air channel 22 is located at the end of the cold air heating pipe 20 near the valve port 7. The cold air heating pipe 20 is equipped with a heating component inside. The top of the air chamber 18 is equipped with a pipeline connection port 27 that is matched and installed with the pipeline structure. The key design feature of this structure lies in the coordination between the overall structure and its components. The air chamber 18 is installed via the mounting base 17 and the fixing ring 19. The air chamber 18 provides an air source, allowing air to enter the pipeline structure. Then, depending on the application scenario, cold or hot air can be selectively used in conjunction with the valve structure for the glue spraying process. While improving the valve structure, the operating principle between the overall structure and the valve structure is also provided. On this basis, a pipeline structure and heating components are added, allowing operators to selectively use different types of cold or hot air for the glue spraying process. Cold air can increase the curing speed of the glue, which is suitable for small-volume or short-duration glue spraying, facilitating the subsequent cleaning process. Hot air can slow down the curing speed of the glue, which is suitable for long-duration glue spraying and batch production. The combination of the two can switch between long and short-duration glue spraying processes, further increasing the versatility and flexibility of operation. The flow channel structure includes an adhesive flow channel 8, an air flow channel 9, and an adhesive outlet 10. The adhesive flow channel 8 is connected to the interior of the adhesive storage section 2, and the opening at one end of the adhesive flow channel 8 is connected to the interior of the adhesive outlet 10. The glue flow channel 8 is directly connected to the glue storage section 2 and leads to the glue outlet 10, forming a continuous, dead-angle-free, low-resistance glue delivery channel. This structure helps to reduce the flow path of glue from the glue storage section 2 to the glue outlet 10, while reducing shear resistance and pressure loss during the flow process. It is conducive to achieving rapid response, and the glue can be sprayed out the instant the valve is opened, meeting the needs of high-speed spraying. At the same time, it avoids the accumulation of glue in the glue flow channel 8, which would cause the glue to solidify into lumps in the glue flow channel 8. Both the airflow channel 9 and the glue flow channel 8 are inclined. The surface of the valve body 4 is provided with a baffle ring area 11 to reduce gas leakage. The baffle ring area 11 is located in the annular area between the glue outlet 10 and the valve body 4. The opening at one end of the airflow channel 9 penetrates the surface of the valve body 4 and communicates with the baffle ring area 11. The use of inclined airflow channel 9 and adhesive flow channel 8 optimizes fluid dynamics performance, reduces flow interference, and avoids the formation of head-on collisions or vortices between the gas and adhesive phases in the intersection area. The airflow is introduced along the inclined direction, which can more smoothly wrap or push the adhesive, achieving efficient air-assisted adhesive dispensing, reducing turbulence and pressure fluctuations, improving spraying stability, preventing adhesive spraying vibration or deviation, and preventing stringing. When the inclined airflow impacts the root of the flowing adhesive column from the side or above, the inclined airflow can generate shear force to quickly cut the adhesive line, reduce obvious stringing, and achieve an effective adhesive breaking effect, avoiding adhesive string contamination of the fabric. The baffle ring area 11 is a ring-shaped groove structure around the glue outlet 10, forming a physical barrier. When compressed air enters the baffle ring area 11 from the airflow channel 9, it is confined within the ring space and cannot diffuse freely in all directions. The gas can only concentrate and act towards the glue outlet 10, significantly reducing gas waste and leakage noise, improving air energy utilization efficiency, and causing the airflow to converge here to form a "ring-shaped air curtain". When the glue spraying is finished, the compressed air forms a ring-shaped airflow in the baffle ring area, blowing out the trace amount of glue residue left at the edge of the glue outlet, preventing glue accumulation and hardening, and keeping the nozzle clean. The drive motor 3 is mounted on the surface of the protective housing 5. The output end of the drive motor 3 is connected to the flow channel structure. One end of the drive motor 3 is electrically connected to a power connection line 14 for connecting to an external power source. The drive motor 3 is externally mounted on the surface of the protective housing 5, rather than embedded inside, which facilitates easy replacement of its installation position and makes its structure independent. When disassembling and assembling, there is no need to disassemble the valve body 4 or the entire structure, making maintenance and replacement more convenient, facilitating rapid on-site repair, reducing equipment downtime, and improving production continuity. In addition, the drive motor 3 is in contact with the outside air but is isolated from the glue circuit or hot air channel, which prevents heat accumulation inside the valve body 4 from causing the drive motor 3 to overheat and extends the service life of the drive motor 3. The drive motor 3 is an air pump motor. When the drive motor 3 is connected to an external power source through the power connection line 14, the drive motor 3 generates driving force to drive the gas, thereby allowing the gas to enter the air outlet flow channel structure, so that the gas can spray the glue and cut it off. The surface of the connector 6 is provided with mounting holes 15 and connecting holes 16 for assisting in the installation of the connector 6. Both mounting holes 15 and connecting holes 16 are used to connect external screws. By passing the external screws through the mounting holes 15 and connecting holes 16 and locking them, the valve can be quickly installed in the designated position, which is suitable for batch assembly and equipment integration. The symmetrically arranged mounting holes 15 and connecting holes 16 in this structure can ensure that the spatial position and angle of the valve in the equipment are accurately fixed, avoid glue spraying deviation, and ensure the consistency of the glue spraying trajectory. In high-speed automated production lines, there may be vibration. The mounting holes 15 and connecting holes 16, together with the screws, can effectively prevent the valve from loosening or shifting, improve the operational stability, and the standardized layout facilitates the quick replacement and universal adaptation of the valve, making it suitable for different models of glue spraying equipment. The valve body 4 and the valve port 7 are detachable. The detachable design allows technicians to easily remove the valve port for internal cleaning or replacement. Replacing the valve port removes residual glue or other impurities, preventing blockage caused by long-term accumulation. When the valve port component is worn, damaged, or needs upgrading, this component can be replaced separately without replacing the entire valve body, reducing maintenance costs. The heating assembly includes one of a heating wire, an electric heating block, or an electric heating base; The heating component (not shown) is located inside the cold air heating pipe 20. Its core function is to heat the cold air from the air chamber 18, which helps to slow down the curing of the adhesive. At the same time, the heated gas is affected by the pressure, which can also increase the jet speed of the airflow and play a role in cutting off the adhesive. The heating wire is lightweight and has a small heat capacity, allowing it to heat up rapidly after being energized, achieving instant heating and meeting the rapid response requirements of high-speed spraying for airflow temperature. The electric heating block is large in size, has a high heat capacity, and exhibits small temperature fluctuations, providing an extremely stable heat source, which is beneficial for maintaining the consistency of the adhesive spraying process. The heating function of the electric heating base is integrated into the fixed base of the valve or pipeline, simplifying the overall structure and reducing the installation of independent heating components. This structure can be installed according to actual needs. A heat-insulating block 23 is provided between the mounting base 17 and the cold air heating pipe 20 to slow down air cooling. A hot air diversion port 24 is provided in the hot air channel 22 to assist the flow channel structure in air diversion. A glue switch control rod 25 is provided inside the valve body 4 to adjust the glue dispensing amount. When the glue switch control rod 25 is lifted upwards, the gap of the glue outlet hole 13 or the glue outlet 10 increases, thereby increasing the glue dispensing amount. The heat-insulating block 23 is made of ceramic, high-temperature resistant plastic, and aluminum silicate fiber to ensure the stability of the hot air temperature. It ensures that the temperature of the airflow entering the hot air channel 22 and the airflow used for glue spraying is high and stable enough, avoiding the decrease of airflow kinetic energy due to mid-way cooling, which affects the glue spraying speed and atomization effect. It also reduces the additional heating power required to compensate for heat loss and reduces energy consumption. The hot air diversion port 24 is used to cooperate with the hot air spray hole 12 to make the hot air sprayed out towards the designated channel, thereby assisting in the completion of the process. The air chamber 18 contains dry ice for auxiliary air cooling. Dry ice is solid carbon dioxide, which absorbs a large amount of heat when it sublimates. It can be selectively placed in the air chamber 18, so that the dry ice can quickly and significantly reduce the temperature of the compressed air or air inside the air chamber entering the air chamber 18, providing a stable and sufficiently low initial temperature for the subsequent cold air section 21. When the heating components are not running, cold air is supplied through the air chamber 18 and the cold air section 21. The cold air can accelerate the complete curing of residual glue and make it brittle. When the glue is sprayed again, the high-speed hot air or glue switch control lever 25 is activated, which can easily blow away or shake off these brittle glue residues, thereby effectively preventing blockage and facilitating the process.

[0009] The emphasis of the airflow channel 9 and adhesive flow channel 8 used in this embodiment is to optimize fluid dynamics performance, reduce flow interference, avoid the formation of head-on collisions or vortices between the gas and adhesive phases in the junction area, and introduce the airflow in an inclined direction so as to more smoothly wrap or push the adhesive, achieve efficient air-assisted adhesive dispensing, reduce turbulence and pressure fluctuations, improve spraying stability, prevent adhesive spraying vibration or deviation, and prevent stringing. Example 2: Please see Figures 1-4 , Figures 10-16 The present invention relates to a high-speed spray valve assembly, comprising an inlet pipe 1, an inlet reservoir 2, a drive motor 3, and a valve body 4. One end of the inlet pipe 1 abuts against the inlet reservoir 2, and one end of the inlet reservoir 2 abuts against the valve body 4. A protective outer shell 5 is provided between the inlet reservoir 2 and the valve body 4. One end of the valve body 4 is a connector 6, one end of which abuts against the end of the inlet reservoir 2. The end of the valve body 4 away from the connector 6 is a valve port 7. The valve body 4 has an internal flow channel structure for assisting in glue and air dispensing. This high-speed spray valve is used for garment glue spraying, and its internal flow channel structure differs from that used in the painting industry. By employing high-speed spray valve technology, rapid and precise glue spraying can be achieved, accelerating the production line and reducing the time of each work cycle. The valve structure controls the amount of glue sprayed and the amount of air emitted, ensuring that the appropriate amount of glue is used, avoiding waste and guaranteeing consistent bonding quality. At the same time, under the blowing force of high-speed gas, the glue is sprayed out in a ring structure, increasing the bonding area. In addition, the texture formed by the gas when the glue is sprayed out helps to bond the fabrics together, thereby increasing the adhesive strength. The flow channel structure includes hot air jet holes 12 and glue outlet holes 13. The hot air jet holes 12 are distributed in a ring at one end of the valve body 4 and penetrate the surface of the valve body 4. The spacing between two adjacent air jet holes 12 is equidistant. The air jet holes 12 have an inclined structure, and the inclined direction of the air jet holes 12 is towards the glue outlet holes 13. The glue outlet holes 13 are respectively connected to the interior of the glue storage part 2 and the valve port 7. Hot air nozzles 12 are arranged in a ring at one end of the valve body 4 and are inclined toward the glue outlet 13, allowing hot air to directly act on the sprayed glue during the spraying process. The hot air can quickly heat and solidify the glue, enhancing its coagulation properties, thereby improving the spraying effect, increasing the glue's diffusion and adhesion, and ensuring a more uniform and finer spraying effect. Because the hot air accelerates the drying speed of the glue surface, it reduces the waiting time in subsequent processes and improves the overall production efficiency. The air nozzles 12 are equidistant and inclined, and the inclined direction is all towards the glue outlet 13, ensuring that the hot air evenly surrounds the glue outlet 13. When the inclined airflow impacts the root of the flowing glue column from the side or above, the inclined airflow can form a shearing force, quickly cutting the glue line, reducing obvious stringing, and achieving an effective glue-breaking effect, avoiding glue string contamination of the fabric. In clothing glue spraying, this glue-breaking effect can increase the aesthetics of the fabric during bonding and avoid glue solidification blocks caused by ineffective glue breaking, which can lead to local protrusions during fabric bonding.

[0010] The focus of this second embodiment is that by replacing the flow channel structure, the hot air nozzles 12 are distributed in a ring at one end of the valve body 4 and are inclined toward the glue outlet 13. This allows the hot air to act directly on the sprayed glue during the spraying process. The hot air can quickly heat and solidify the glue, enhancing its coagulation properties, thereby improving the glue spraying effect, increasing the glue's diffusion and adhesion, ensuring a more uniform and finer spraying effect, and reducing the waiting time in subsequent processes due to the accelerated drying speed of the glue surface, thus improving the overall production efficiency. The air jet holes 12 are equidistant and inclined, and the inclined direction is towards the glue outlet hole 13. This ensures that the hot air evenly surrounds the glue outlet hole 13. When the inclined airflow impacts the root of the flowing glue column from the side or above, the inclined airflow can form a shearing force to quickly cut the glue line, reduce obvious stringing, and achieve an effective glue-breaking effect. This avoids glue string contamination of the fabric and increases the aesthetics of the fabric during bonding.

[0011] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
