Description

Technical Field

[0001] This utility model relates to the field of adhesive spraying equipment technology, and in particular to an integrated adhesive spraying atomizing valve. Background Technology

[0002] A spray adhesive atomizing valve is a device that converts glue or other adhesives into tiny droplets and discharges them in the form of a spray. Compared to other glue application methods such as dip coating or spin coating, atomized spray adhesive technology can not only improve the uniformity of glue application, but also greatly reduce the amount of glue used, thereby reducing the emission of harmful VOCs, which is in line with the trend of green manufacturing. Therefore, in recent years, more and more glue spraying atomizing valves have appeared on the market. For example, Chinese utility model patent CN221086018U discloses a multi-mode atomizing component and its atomizing valve. The atomizing valve includes a multi-mode atomizing component, a valve body, a cylinder assembly, a glue delivery solenoid valve, an air delivery solenoid valve, and a valve stem. The multi-mode atomizing component includes a nut sleeve, an atomizing sleeve, an atomizing nozzle, a glue delivery sleeve, and a glue spraying nozzle. The valve body is connected to the atomizing sleeve and the glue delivery sleeve through the nut sleeve. The valve body is provided with an air inlet communicating with the atomizing hole, a second valve hole communicating with the glue delivery sleeve, and a glue inlet communicating with the second valve hole. The valve stem is movably disposed on the glue delivery sleeve, the second valve hole, and the glue spraying hole, and is connected to the piston of the cylinder assembly. The glue delivery solenoid valve is connected to the glue inlet hole. The air delivery solenoid valve is connected to the air inlet hole.

[0003] However, the aforementioned atomizing valve, with its glue delivery solenoid valve connected to the cylinder assembly via connectors and air pipes, and its air delivery solenoid valve also connected to the air inlet via connectors and air pipes, not only results in numerous assembly steps for the atomizing valve, consuming significant manpower and time, but also leads to instability in the gas pressure entering the atomizing valve due to expansion or contraction of the air pipes as atmospheric temperature changes. Furthermore, when the air pipe routing is complex, the travel distance of the compressed gas from the air source to the atomizing valve increases, resulting in slower cylinder assembly operation and atomizing air intake response, thus affecting the atomization effect. In addition, the aforementioned atomizing valve does not allow for adjustment of the glue dispensing rate, failing to meet the needs of applications requiring different glue dispensing volumes.

[0004] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated glue spraying atomizing valve, which can solve the technical problems in existing atomizing valves, such as the need for the solenoid valve to be connected to the air inlet through an air pipe, resulting in inconvenient assembly and connection, unstable gas pressure entering the atomizing valve, slow response speed of the atomizing valve, and the inability to meet the technical requirements of different glue dispensing volumes.

The air inlet end of the first solenoid valve is connected to the first air inlet through the first air passage, and the air outlet end is connected to the valve stem cylinder through the first air passage. The air inlet end of the second solenoid valve is connected to the second air inlet through the second air passage, and the air outlet end is connected to the atomizing gas channel through the second air passage.

[0012] Furthermore, the valve body assembly also includes a second connecting block, which is installed on the outer side wall of the main valve body; the glue inlet is disposed on the second connecting block, and the second connecting block is provided with a connecting channel, one end of which is connected to the glue inlet and the other end of which is connected to the glue outlet channel.

[0013] Furthermore, the integrated glue spraying atomizing valve also includes an adjustment mechanism, which is located on the top of the main valve body and is used to control the glue dispensing volume at the glue outlet.

[0019] (2) The integrated glue spraying atomizing valve of this utility model adjusts the stroke of the valve rod moving upward by setting an adjustment mechanism, so as to change the size of the glue discharge gap between the valve rod and the glue outlet, thereby facilitating the control of the glue discharge amount and meeting different usage needs.

[0020] (3) By setting a locking tooth and an elastic locking rod assembly that cooperate with each other in the adjustment mechanism, the user can hear a "click" and feel a slight vibration every time the screw sleeve turns through one tooth in the locking tooth. Since the number of teeth set on the outer wall of the locking tooth is fixed, the angle value corresponding to each tooth turned by the screw sleeve can be known. Therefore, the user can directly perceive the angle turned by the screw sleeve through the "click" sound and vibration during the adjustment process, resulting in a better user experience.

Detailed Implementation

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0029] Example 1

[0030] like Figures 1 to 5 As shown, this utility model provides an integrated glue atomizing valve, including a valve body assembly 1, a first solenoid valve 2, and a second solenoid valve 3. The valve body assembly 1 internally houses a valve stem cylinder 4, a glue outlet channel 5, an atomizing gas channel 6, and a valve stem 7. The output end of the valve stem cylinder 4 is connected to the valve stem 7, and the valve stem 7 is movably inserted into the glue outlet channel 5. A glue outlet 51 is provided at the end of the glue outlet channel 5 away from the valve stem cylinder 4. The valve stem 7 controls the opening and closing of the glue outlet 51. A glue inlet 81 is connected to the valve body assembly 1. The valve body assembly 1 includes a first air inlet 82 and a second air inlet 83. The glue inlet 81 is connected to the glue outlet channel 5. The valve body assembly 1 also includes several air passages. The first solenoid valve 2 and the second solenoid valve 3 are mounted on the valve body assembly 1. The air inlet of the first solenoid valve 2 is connected to the first air inlet 82 via the air passages, and its outlet is connected to the valve stem cylinder 4 via the air passages. The air inlet of the second solenoid valve 3 is connected to the second air inlet 83 via the air passages, and its outlet is connected to the atomizing gas channel 6 via the air passages. Specifically, the glue outlet 51 and the end of the valve stem 7 near the glue outlet 51 are both conical. When the valve stem 7 moves downwards, it blocks the glue outlet 51, thus closing it. When the valve stem 7 moves upwards, there is a gap between the valve stem 7 and the glue outlet 51, thus opening the glue outlet 51.

[0031] When the first solenoid valve 2 and the second solenoid valve are installed on the valve body assembly 1, the air inlet and outlet of the first solenoid valve 2 and the air inlet and outlet of the second solenoid valve 3 are connected to the air passage in the valve body assembly 1. Therefore, the air inlet and outlet of the first solenoid valve 2 can be directly connected to the first air inlet 82 and the valve stem cylinder 4 through the air passage, respectively. The air inlet and outlet of the second solenoid valve 3 can be directly connected to the second air inlet 83 and the atomizing gas passage 6 through the air passage, respectively. In actual use, the first air inlet 82 and the second air inlet 83 are connected to the air source. The gas in the air source enters the first solenoid valve 2 through the first air inlet 82 and the air passage. After passing through the first solenoid valve 2, the gas enters the valve stem cylinder 4 through the air passage. The movement direction of the valve stem cylinder 4 and the valve stem 7 is controlled by opening and closing the first solenoid valve 2. When the output end of the valve stem cylinder 4 extends, thereby driving the valve stem 7 to move downward, the glue outlet 51 is closed and glue dispensing stops. When the output end of the valve stem cylinder 4 retracts, thereby driving the valve stem 7 to move upward, the glue outlet 51 is opened and glue dispensing begins. Therefore, the glue dispensing frequency of the glue outlet 51 is controlled by the first solenoid valve 2. In addition, the gas in the gas source enters the second solenoid valve 3 through the second air inlet 83 and the air passage. After passing through the second solenoid valve 3, the gas enters the atomizing gas channel 6 through the air passage. The opening and closing of the second solenoid valve 3 controls whether the gas enters the atomizing gas channel 6, that is, the second solenoid valve 3 controls the air intake frequency in the atomizing gas channel 6.

[0032] In this embodiment, the first solenoid valve 2 and the first air inlet 82, as well as the second solenoid valve 3 and the second air inlet 83, can be directly connected through the air passage in the valve body assembly, without the need for additional interfaces and air pipes. This design makes the overall assembly and connection of the integrated adhesive spraying atomizing valve simple and convenient, saving assembly time and manpower. On the other hand, since the valve body is made of metal, the air passage is not easily expanded or contracted when the atmospheric temperature changes, thus keeping the gas pressure entering the valve stem cylinder and the atomizing gas channel stable and ensuring the atomization effect. Furthermore, the connection through the air passage helps to greatly shorten the stroke of compressed gas from the air source to the atomizing valve, thereby ensuring the actuation speed of the valve stem cylinder and the response speed of the atomizing air intake, enabling the integrated adhesive spraying atomizing valve to achieve high-frequency and high-speed response.

[0033] Furthermore, such as Figure 1-5 As shown, the valve body assembly 1 includes a main valve body 11, the valve stem cylinder 4 includes a cylinder cavity 41 and a piston 42, the cylinder cavity 41 is opened inside the main valve body 11, the piston 42 is movably disposed in the cylinder cavity 41, and the valve stem 7 is connected to the piston 42.

[0034] Furthermore, such as Figure 1-5As shown, the valve body assembly 1 further includes an atomizing nozzle 10, which is disposed at the bottom end of the main valve body 11. The bottom end of the atomizing nozzle 10 has an outlet 101. One end of the adhesive dispensing channel 5, away from the outlet 51, is disposed in the main valve body 11, and the other end, closer to the outlet 51, extends into the atomizing nozzle 10. One end of the atomizing gas channel 6 is disposed in the main valve body 11, and the other end extends into the atomizing nozzle 10. Both the adhesive dispensing channel 5 and the atomizing gas channel 6 are connected to the outlet 101. Specifically, the atomizing gas channel 6 is disposed around the outside of the adhesive dispensing channel 5.

[0035] Furthermore, the valve body assembly 1 also includes a first connecting block 12, which is mounted on the outer wall of the main valve body 11; the first air inlet 82 and the first solenoid valve 2 are disposed on the main valve body 11, and the second air inlet 83 and the second solenoid valve 3 are disposed on the first connecting block 12. Preferably, the plurality of air passages include a first air passage 16 and a second air passage. The first air passage 16 is disposed in the main valve body 11, and the second air passage is disposed in the first connecting block 12. The air inlet end of the first solenoid valve 2 is connected to the first air inlet 82 through the first air passage 16, and the air outlet end is connected to the valve stem cylinder 4 through the first air passage 16; the air inlet end of the second solenoid valve 3 is connected to the second air inlet 83 through the second air passage, and the air outlet end is connected to the atomizing gas channel 6 through the second air passage. The specific arrangement of the first air passage 16 and the second air passage is determined according to the actual communication requirements and will not be described in detail here. In addition, a fixing rod 15 is connected to the side of the first connecting block 12 away from the main valve body 11. The fixing rod 15 is used to connect to external automation equipment.

[0036] Furthermore, the valve body assembly 1 also includes a second connecting block 13, which is installed on the outer side wall of the main valve body 11; the glue inlet 81 is disposed on the second connecting block 13, and the second connecting block 13 is provided with a connecting channel, one end of which is connected to the glue inlet 81 and the other end of which is connected to the glue outlet channel 5.

[0037] Example 2

[0038] like Figure 1-5As shown, based on Embodiment 1, the integrated glue atomizing valve in Embodiment 2 further includes an adjusting mechanism 9. The adjusting mechanism 9 is located at the top of the main valve body 11 and is used to control the glue dispensing volume of the glue outlet 51. Specifically, the adjusting mechanism 9 includes a screwing assembly, which includes a screwing sleeve 911 and a limiting rod 912 disposed within the screwing sleeve 911. The screwing sleeve 911 is located on the upper side of the main valve body 11. One end of the limiting rod 912, away from the screwing sleeve 911, is inserted into the main valve body 11 and extends into the interior of the cylinder cavity 41. The limiting rod 912 is threadedly connected to the main valve body 11. A scale 913 is provided on the upper end face of the screwing sleeve 911. Specifically, the limiting rod 912 is connected to the screwing sleeve 911 via a connecting rod 914, and the scale 913 is in Arabic numerals.

[0039] In this embodiment, a limiting rod 912 is used to limit the upward stroke of the piston 42 and the valve stem 7. Since the limiting rod 912 is threadedly connected to the main valve body 11, rotating the screw sleeve 911 drives the limiting rod 912 to rotate synchronously, thereby adjusting the length of the limiting rod 912 extending into the cylinder cavity 41. When the length of the limiting rod 912 extending into the cylinder cavity 41 increases, the upward stroke of the piston 42 and the valve stem 7 becomes shorter, that is, the glue discharge gap between the valve stem 7 and the glue outlet 51 becomes smaller, and the glue discharge amount becomes less. When the length of the limiting rod 912 extending into the cylinder cavity 41 becomes shorter, the upward stroke of the piston 42 and the valve stem 7 becomes longer, that is, the glue discharge gap between the valve stem 7 and the glue outlet 51 becomes larger, and the glue discharge amount becomes more. Therefore, the glue discharge amount is controlled by the adjusting mechanism 9. Furthermore, by providing a scale 913 on the upper end face of the screw sleeve 911, users can easily adjust the screw sleeve 911 to the corresponding scale 913 position according to the required amount of adhesive dispensing.

[0040] Furthermore, the adjusting mechanism 9 also includes a locking tooth 92 and an elastic locking rod assembly. One end of the locking tooth 92 is positioned above the main valve body 11 and inside the screwing sleeve 911, while the other end is inserted into the main valve body 11 and extends into the cylinder cavity 41. The locking tooth 92 has a through channel 921 through which the limiting rod 912 passes. The through channel 921 is connected to the cylinder cavity 41. The outer peripheral sidewall of the limiting rod 912 is provided with external threads. The through channel 921 is provided with an internal thread that matches the external thread; the outer peripheral side of the locking tooth 92 is uniformly provided with a plurality of protruding teeth, and a tooth groove is formed between adjacent protruding teeth; the elastic locking rod assembly is disposed on the cylindrical wall of the screwing sleeve 911 and can contact the locking tooth 92; during the synchronous rotation of the screwing sleeve 911, the elastic locking rod assembly reciprocates along the radial direction of the screwing sleeve 911 under the action of the locking tooth 92. Preferably, the elastic locking rod assembly includes a locking rod 931 and a spring 932; the cylindrical wall of the screwing sleeve 911 is provided with a placement hole 933, wherein the placement hole 933 is disposed through the cylindrical wall; the locking rod 931 is movably disposed in the placement hole 933; the outer side wall of the screwing sleeve 911 is provided with an annular groove 934 corresponding to the position of the placement hole 933; and the spring 932 is sleeved in the annular groove 934. Specifically, the outer peripheral wall of the screw-on sleeve 911 is provided with anti-slip texture to prevent slippage when rotating the screw-on sleeve 911. It is understood that the spring 932 can also adopt other installation methods. For example, the end of the placement hole 933 away from the locking tooth 92 is closed, and the spring 932 is placed between the closed end of the placement hole 933 and the locking rod 931, as long as the reciprocating movement of the locking rod 931 can be realized.

[0041] In actual use, when it is necessary to adjust the dispensing amount, the user manually rotates the screw sleeve 911. The locking lever 931 rotates synchronously with the screw sleeve 911. When the locking lever 931 rotates to contact the protruding teeth in the locking tooth member 92, the locking lever 931 moves away from the locking tooth member 92 along the placement hole 933 (that is, along the radial direction of the screw sleeve 911) under the action of the protruding teeth. A small part of the locking lever 931 protrudes from the placement hole 933 and compresses the spring 932, causing the spring 932 to deform. When the locking lever 931 rotates to be aligned with the tooth groove in the locking tooth member 92, the spring 932 returns to its original position, which will drive the locking lever 931 to move away from the placement hole 933 (that is, along the radial direction of the screw sleeve 911) away from the locking tooth member 92. The sleeve 911 moves radially toward the toothed part 92 and collides with the toothed part at the toothed position. At this time, a "click" sound is made and the user can feel the slight vibration of the collision. This setting allows the user to hear a "click" sound and feel a slight vibration every time the sleeve 911 turns through a tooth. Since the number of teeth on the outer wall of the toothed part 92 is fixed, the angle value corresponding to each tooth that the sleeve 911 turns through can be known. Therefore, the user can directly perceive the angle that the sleeve 911 has turned through through the "click" sound and vibration during the adjustment process, resulting in a better user experience.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
