Description

Technical Field

[0001] This invention relates to the field of adhesive coating technology, and in particular to a coating valve. Background Technology

[0002] The valve body of a coating valve typically contains a valve stem, which opens or closes the spray nozzle by moving the stem. The opening of the nozzle is controlled by the travel of the valve stem. A stroke adjustment mechanism is usually located at the end of the valve stem opposite the spray nozzle. This mechanism includes an adjusting motor and an adjusting bolt threaded to the valve body. The motor drives the adjusting bolt to rotate, thus adjusting the travel of the valve stem. To reduce dead zones, the valve body is often mounted on a rotatable frame, allowing adjustment of the spray nozzle angle and improving versatility. However, the presence of the stroke adjustment mechanism on the valve body results in a larger operating space during rotation, making the valve more susceptible to collisions and interference with other objects during operation. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a coating valve that can not only adjust the spray angle, but also effectively improve the problem of collision and interference with other objects.

[0004] The coating valve of this invention includes an adjusting motor assembly, an adjusting bolt, a movable trowel, a valve body, and a telescopic drive structure. The adjusting motor assembly is provided with an output shaft. One end of the valve body is provided with a spray nozzle, and a valve stem for controlling the opening and closing of the spray nozzle is provided inside. The valve body is rotatably mounted, and the orientation of the spray nozzle can be adjusted by rotating the valve body. One end of the movable trowel is driven and connected to the output shaft, and it is slidably mounted on one side of the valve body along its own axis. The adjusting bolt is threaded to the valve body, and the movement stroke of the valve stem can be adjusted by rotating the adjusting bolt. The telescopic drive structure drives and connects to the movable trowel, and when the valve body is rotated so that the adjusting bolt faces the movable trowel, the telescopic drive structure can drive the movable trowel to slide, so that the movable trowel drives and connects to the adjusting bolt or separates from the adjusting bolt.

[0005] The coating valve according to embodiments of the present invention has at least the following beneficial effects:

[0006] In this embodiment, because the valve body is rotatable and the orientation of the spray nozzle can be adjusted by rotating the valve body, the glue spray angle can be adjusted by rotating the valve body, thereby improving the versatility of the coating valve. Simultaneously, due to the separable design between the movable trowel and the adjusting bolt, when the opening of the spray nozzle needs to be adjusted, simply rotate the valve body so that the adjusting bolt on the valve body faces the movable trowel. Then, using a telescopic drive structure, drive the movable trowel to approach and connect to the adjusting bolt. The adjusting motor assembly then drives the movable trowel to rotate the adjusting bolt, thereby adjusting the travel of the valve stem and thus changing the opening of the spray nozzle when the coating valve is working. During spraying, simply use the telescopic drive structure to disengage the movable trowel from the adjusting bolt, and the valve body can rotate normally to adjust the glue spray angle at any time. Furthermore, because the adjusting motor assembly and the movable trowel are separated from the rotating valve body at this time, the required space for valve body rotation is relatively smaller, thus effectively improving the problem of collision and interference with other objects.

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, left, right, front, back, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0037] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0038] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0039] The following is for reference only. Figure 1 To be continued Figure 15 This describes the coating valve according to an embodiment of the present invention.

[0040] Reference Figures 1 to 4 According to some embodiments of the present invention, the coating valve includes a valve body 1000, an adjusting bolt 1700, an adjusting motor assembly 5000, a movable trowel 3000, and a telescopic drive structure.

[0041] Among them, reference Figure 2 , Figure 3 , Figure 10 and Figure 11 The valve body 1000 is rotatable and has a spray nozzle 1310 at one end. The spray nozzle 1310 is used to spray glue to achieve glue coating. Therefore, by rotating the valve body 1000, the orientation of the spray nozzle 1310 can be adjusted, thereby changing the spray angle of the glue. In addition, the valve body 1000 also has a sliding valve stem 1400 inside. One end of the valve stem 1400 extends to the vicinity of the spray nozzle 1310. By driving the valve stem 1400 to slide, the spray nozzle 1310 can be closed or opened. At the same time, the opening degree of the spray nozzle 1310 is determined by the distance between the valve stem 1400 and the spray nozzle 1310 when the valve stem 1400 opens the spray nozzle 1310. If the distance between the valve stem 1400 and the spray nozzle 1310 is larger, the opening degree of the spray nozzle 1310 is larger. Therefore, the opening degree of the spray nozzle 1310 can be adjusted by adjusting the sliding stroke of the valve stem 1400.

[0042] Reference Figure 2 and Figure 10 and Figure 11The adjusting bolt 1700 is threaded onto the valve body 1000 and faces the end of the valve stem 1400 away from the glue spray nozzle 1310. The adjusting bolt 1700 can prevent the valve stem 1400 from moving away from the glue spray nozzle 1310. By rotating the adjusting bolt 1700, the depth of the adjusting bolt 1700 entering the valve body 1000 can be adjusted, thereby changing the distance between the adjusting bolt 1700 and the valve stem 1400, and thus realizing the adjustment of the movement stroke of the valve stem 1400.

[0043] Reference Figures 4 to 6 The movable screwdriver 3000 is slidably disposed on one side of the valve body 1000 along its own axis. By rotating the valve body 1000, the adjusting bolt 1700 can be directed toward the movable screwdriver 3000. Sliding the movable screwdriver 3000 can drive one end of the movable screwdriver 3000 to connect to the adjusting bolt 1700, or cause the movable screwdriver 3000 to separate from the adjusting bolt 1700.

[0044] Reference Figures 2 to 4 The adjusting motor assembly 5000 is located on one side of the movable screwdriver 3000, and the adjusting motor assembly 5000 is provided with an output shaft. The output shaft is driven to the end of the movable screwdriver 3000 away from the valve body 1000. The output shaft is used to output torque so that when the movable screwdriver 3000 and the adjusting bolt 1700 are in the drive connection state, the movable screwdriver 3000 can drive the adjusting bolt 1700 to rotate.

[0045] The telescopic drive structure drives the movable screwdriver 3000 and drives the movable screwdriver 3000 to slide along its own axis. When the valve body 1000 rotates to the state where the adjusting bolt 1700 faces the movable screwdriver 3000, the telescopic drive structure can drive the movable screwdriver 3000 to slide, thereby causing the movable screwdriver 3000 to drive the adjusting bolt 1700 or separate from the adjusting bolt 1700.

[0046] It should be understood that, in the coating valve of this embodiment of the invention, since the valve body 1000 is rotatably configured, and the orientation of the spray nozzle 1310 can be adjusted by rotating the valve body 1000, the glue spray angle can be adjusted by rotating the valve body 1000, thereby improving the versatility of the coating valve. Simultaneously, due to the separable design between the movable trowel 3000 and the adjusting bolt 1700, when it is necessary to adjust the opening of the spray nozzle 1310, simply rotate the valve body 1000 so that the adjusting bolt 1700 on the valve body 1000 faces the movable trowel 3000. Then, by means of a telescopic drive structure, the movable trowel 3000 is driven to approach and connect to the adjusting bolt 1700, thus achieving the desired glue spray angle adjustment. The adjusting motor assembly 5000 drives the movable trowel 3000 to rotate the adjusting bolt 1700, thereby adjusting the travel of the valve stem 1400 and changing the opening of the adhesive nozzle 1310 when the coating valve is working. During the spraying operation, the movable trowel 3000 can be disengaged from the adjusting bolt 1700 by means of the telescopic drive structure, and the valve body 1000 can rotate normally to adjust the adhesive spraying angle at any time. Since the adjusting motor assembly 5000 and the movable trowel 3000 are separated from the rotating valve body 1000 at this time, the space required for the valve body 1000 to rotate is relatively smaller, thus effectively improving the problem of collision and interference with other objects.

[0047] It is understood that, in some of these embodiments, reference is made to... Figure 7 The regulating motor assembly 5000 includes a servo motor 5100 and a reducer 5200. The motor shaft of the servo motor 5100 is connected to the input end of the reducer 5200, and the output end of the reducer 5200 forms an output shaft for outputting torque. It should be understood that in some other embodiments, the regulating motor assembly 5000 includes a servo motor 5100, and the motor shaft of the servo motor 5100 extends to the outside of the stator of the servo motor 5100 and directly constitutes the output shaft.

[0048] It is understandable that, in order to achieve the drive connection between the output shaft and the movable screwdriver 3000, and to avoid affecting the normal sliding of the movable screwdriver 3000, in some embodiments, reference is made to... Figure 7 and Figure 8 The coating valve also includes a sliding coupling 5300, which is connected to the output shaft. The sliding coupling 5300 has a protruding non-cylindrical connecting post 5310 on the side facing the movable bit 3000. The movable bit 3000 has a connecting groove 3100 that matches the connecting post 5310 at the end facing the sliding coupling 5300, and is slidably fitted onto the connecting post 5310 through the connecting groove 3100. It can be understood that the depth of the connecting groove 3100 and the length of the connecting post 5310 are set to be greater than the maximum travel distance that the movable bit 3000 needs to slide, thereby preventing the connecting post 5310 from disengaging from the connecting groove 3100.

[0049] It is understandable that, in order to enable the movable lever 3000 to both drive and disengage from the adjusting bolt 1700, in some embodiments, reference is made to... Figure 6 The movable screwdriver 3000 has a non-circular socket groove 3200 at one end facing the valve body 1000, and the adjusting bolt 1700 has a protrusion 1710 that matches the socket groove 3200. Thus, when the valve body 1000 rotates to the position where the adjusting bolt 1700 faces the movable screwdriver 3000, the telescopic drive structure drives the movable screwdriver 3000 to slide closer to the valve body 1000, allowing the movable screwdriver 3000 to be sleeved onto the protrusion 1710 through the socket groove 3200. Because the protrusion 1710 is not circular, when the movable wrench 3000 rotates under the drive of the adjusting motor assembly 5000, it will drive the adjusting bolt 1700 to rotate. After the stroke of the valve stem 1400 is adjusted, the telescopic drive structure drives the movable wrench 3000 to slide away from the valve body 1000, which will separate the sleeve groove 3200 from the protrusion 1710, thus separating the movable wrench 3000 from the adjusting bolt 1700. For example, in one embodiment, referring to... Figure 9 and Figure 10 The center of the end face of the movable lever 3000 facing the valve body 1000 is provided with a regular hexagonal socket groove 3200, while the end of the adjusting bolt 1700 facing away from the valve stem 1400 is provided with a regular hexagonal protrusion 1710 that matches the socket groove 3200.

[0050] It is understandable that, to facilitate the rapid driving of the movable bit 3000, the movable bit 3000 is pneumatically driven, and to reduce the overall size of the coating valve in the axial direction of the movable bit 3000, in some embodiments, reference is made to... Figures 4 to 6 The telescopic drive structure includes a drive sleeve 4100 and a first piston 4200. The movable screwdriver 3000 passes through the drive sleeve 4100, and the first piston 4200 is sleeved on the movable screwdriver 3000. A variable air chamber 4300 is formed between the first piston 4200, the drive sleeve 4100, and the movable screwdriver 3000. By passing air into the variable air chamber 4300 or venting air from the variable air chamber 4300, the first piston 4200 can be subjected to force, thereby driving the movable screwdriver 3000 to slide.

[0051] Furthermore, it should be understood that, in order to ensure that the movable bit 3000 can remain in a position relatively far from the valve body 1000 under normal conditions, thereby avoiding affecting the normal rotation of the valve body 1000, in some embodiments, the telescopic drive structure further includes an elastic element. The elastic element connects the drive sleeve 4100 and the movable bit 3000, and the elastic restoring force of the elastic element can drive the movable bit 3000 to move and reset to the side away from the valve body 1000.

[0052] For example, in one embodiment, reference Figure 6 Specifically, the variable air chamber 4300 is formed on the side of the first piston 4200 near the valve body 1000, and the elastic element is a compression spring (not shown in the figure). The compression spring is disposed inside the variable air chamber 4300, and one end of the compression spring abuts against the part of the movable screwdriver 3000 connected to the first piston 4200, while the other end of the compression spring abuts against the inner wall of the drive sleeve 4100 near the valve body 1000. Thus, the elastic force of the compression spring can drive the first piston 4200 and the movable screwdriver 3000 to move away from the valve body 1000. When it is necessary to drive the movable screwdriver 3000 closer to the adjusting bolt 1700, air can be drawn from the variable air chamber 4300 to make the first piston 4200 and the movable screwdriver 3000 move towards the valve body 1000 under atmospheric pressure.

[0053] Alternatively, in another embodiment, the elastic element can also be a tension spring, and the variable air chamber 4300 is formed on the side of the first piston 4200 away from the valve body 1000. One end of the tension spring is connected to the movable screwdriver 3000, and the other end of the tension spring is connected to the inner wall of the drive sleeve 4100 on the side away from the valve body 1000. Thus, the elastic force of the tension spring can drive the first piston 4200 and the movable screwdriver 3000 to move away from the valve body 1000. When it is necessary to drive the movable screwdriver 3000 closer to the adjusting bolt 1700, it is only necessary to vent air into the variable air chamber 4300, so that the first piston 4200 and the movable screwdriver 3000 can move towards the side closer to the valve body 1000 under the air pressure of the compressed gas in the variable air chamber 4300.

[0054] It is understood that, in order to achieve the rotation of the valve body 1000, in some embodiments of the present invention, reference is made to... Figures 1 to 3The coating valve also includes a rotating frame 6000 and an electric slip ring 7000. The electric slip ring 7000 includes a stator 7100 and a rotor 7200. The stator 7100 is fixedly mounted, and the rotor 7200 is rotatably connected to the stator 7100. The rotating frame 6000 is connected to one end of the rotor 7200, and the valve body 1000 is rotatably connected to the rotating frame 6000. The rotation axis of the valve body 1000 about the rotating frame 6000 is perpendicular to the rotation axis of the rotor 7200 about the stator 7100. Thus, with the help of the electric slip ring 7000 and the rotating frame 6000, the valve body 1000 can rotate about two mutually perpendicular axes, thereby further improving the working space range and versatility of the coating valve.

[0055] It should be understood that, in one embodiment, reference is made to... Figure 3 , Figure 4 , Figure 6 and Figure 12 The rotor portion 7200, rotating around the stator portion 7100, has its rotation axis collinear with the rotation axis of the movable screwdriver 3000. The rotor portion 7200 is hollow and has a first central hole 7210. The rotating frame 6000 includes a flange portion 6300, which is connected to the rotor portion 7200. The flange portion 6300 has a second central hole 6310 at its center. The movable screwdriver 3000 and the drive sleeve 4100 pass through the first central hole 7210 and the second central hole 6310, thereby preventing the electric slip ring 7000 and the rotating frame 6000 from affecting the drive connection between the movable screwdriver 3000 and the adjusting bolt 1700 on the valve body 1000. Furthermore, to better limit the stroke of the valve stem 1400, refer to... Figure 6The central axis of the adjusting bolt 1700 is collinear with the central axis of the valve stem 1400. Simultaneously, the rotation axis of the valve body 1000 around the rotating frame 6000 is perpendicular to the extension direction of the valve stem 1400. Since the spray direction of the adhesive nozzle 1310 is the same as the extension direction of the valve stem 1400, the spray direction of the valve body 1000 will also be perpendicular to the rotation axis of the valve body 1000 around the rotating frame 6000. Because the central axis of the stator 7100 will be vertical when the coating valve is in use, the rotation axis of the rotor 7200 around the stator 7100 will also be vertical. Furthermore, the axis of rotation of the valve body 1000 around the rotating frame 6000 will be in the horizontal direction. Therefore, with the above structure, on the one hand, the valve body 1000 can adjust the spray angle on the vertical plane, and on the other hand, the nozzle 1310 can be tilted to point to any position on the horizontal plane. Regardless of the horizontal position of the nozzle 1310 of the tilted valve body 1000, the adjusting bolt 1700 can be directed toward the movable squeegee 3000 after the valve body 1000 is driven to rotate relative to the rotating frame 6000, thereby simplifying the steps of adjusting the stroke of the valve stem 1400.

[0056] It is understood that, in one embodiment, the stator portion 7100 is internally provided with a device for connecting an adhesive supply (e.g., Figure 1 The rotor 7200 is provided with a glue supply path (not shown in the figure) for the glue storage cylinder 2200 and a gas supply path (not shown in the figure) for connecting to a compressed gas supply device (e.g., a gas pipeline connected to an air compressor). The rotor 7200 is provided with a glue inlet path (not shown in the figure) connecting to the glue supply path and a gas inlet path (not shown in the figure) connecting to the gas supply path. (Refer to...) Figure 6 and Figure 12The rotating frame 6000 is provided with a glue flow channel 6100 with one end connected to the glue inlet flow path and an air passage 6200 with one end connected to the air inlet flow path; the valve body 1000 is provided with a rotating connecting part, a glue inlet 1114 and an air inlet, and is rotatably connected to the rotating frame 6000 through the rotating connecting part, while the glue inlet 1114 and the air inlet are provided in the rotating connecting part and are respectively connected to the second end of the glue flow channel 6100 and the second end of the air passage 6200. With the above structure, there is no need to install external pipelines between the valve body 1000, the rotating frame 6000, and the electric slip ring 7000 to complete the glue or air intake. The glue can enter the valve body 1000 in sequence through the glue supply path, the glue intake path, the glue channel 6100, and the glue inlet 1114. The compressed gas that controls the operation of the valve body 1000 can enter the valve body 1000 in sequence through the air supply path, the air intake path, the air channel 6200, and the air inlet. Therefore, when driving the valve body 1000 to rotate around the rotating frame 6000, there will be no problem of external pipelines being bent, blocked, broken, or tangled together, thus affecting the normal glue spraying. At the same time, the coating valve is also cleaner and more aesthetically pleasing overall.

[0057] It is understood that, in order to facilitate the connection of the valve body 1000 and improve the stability of the valve body 1000 installation, in some embodiments, reference is made to the figure. Figures 12 to 14 The rotating frame 6000 includes a first connecting arm 6400 and a second connecting arm 6500. The first connecting arm 6400 and the second connecting arm 6500 are located on both sides of the valve body 1000, and one end of each is connected to the flange portion 6300. The rotating connection portion includes a first connecting portion 1110 and a second connecting portion 1120 respectively disposed on opposite sides of the valve body 1000. The first connecting portion 1110 and the second connecting portion 1120 are rotatably connected to the first connecting arm 6400 and the second connecting arm 6500, respectively. Thus, the first connecting arm 6400 and the second connecting arm 6500 can support the valve body 1000 on both sides, thereby improving the valve's stability. The valve body 1000 is installed stably; and, in order to allow the adhesive and compressed air to enter the valve body 1000 from both sides respectively; wherein, the second end of the adhesive flow channel 6100 is provided at the first connecting arm 6400, and the adhesive inlet 1114 is correspondingly provided at the first connecting part 1110, so that the adhesive will enter the valve body 1000 from one side after passing through the first connecting arm 6400 and the first connecting part 1110; the second end of the air channel 6200 is provided at the second connecting arm 6500, and the air inlet is correspondingly provided at the second connecting part 1120, so that the compressed air enters the valve body 1000 from the opposite side after passing through the second connecting arm 6500 and the second connecting part 1120.

[0058] It is understandable that, in order to achieve glue injection while avoiding affecting the rotation of the first connecting part 1110 relative to the first connecting arm 6400, in some embodiments, refer to Figures 10 to 14A first half-shaft 6410 is provided on the side of the first connecting arm 6400 facing the first connecting portion 1110, and the second end of the glue channel 6100 is provided through the center of the first half-shaft 6410. The first connecting portion 1110 is provided with a first rotating groove 1111 that mates with the first half-shaft 6410. The first half-shaft 6410 is inserted into the first rotating groove 1111, and the glue inlet 1114 is provided on the bottom or wall of the first rotating groove 1111. Furthermore, to better ensure the communication between the glue inlet 1114 and the second end of the glue channel 6100, in some embodiments, refer to... Figure 14 The first half-shaft 6410 and the bottom and wall of the first rotating groove 1111 form a communicating cavity 1112. The glue inlet 1114 and the second end of the glue channel 6100 are both connected to the communicating cavity 1112. Since the second end of the glue channel 6100 passes through the center of the first half-shaft 6410, the second end of the glue channel 6100 will always be connected to the communicating cavity 1112 during the rotation of the first connecting part 1110 relative to the first half-shaft 6410. Moreover, since the glue inlet 1114 is located at the bottom or wall of the first rotating groove 1111 that participates in forming the communicating cavity 1112, the glue inlet 1114 will also always be connected to the second end of the glue channel 6100.

[0059] It should be understood that, in order to ensure that the second end of the glue flow channel 6100 is always connected to the glue inlet 1114, in some other examples, the first half-shaft 6410 may be abutted against the bottom of the first rotating groove 1111, and the glue inlet 1114 may be located at the center of the bottom of the first rotating groove 1111.

[0060] It should be understood that, in some of these embodiments, reference is made to... Figure 10 and Figure 11The valve body 1000 includes a valve housing 1100, a glue reservoir 1200, a nozzle 1300, a valve stem 1400, a second piston 1500, and a return spring 1600. The nozzle 1300 is connected to one end of the glue reservoir 1200, and the glue outlet 1310 is located at the end of the nozzle 1300 opposite to the glue reservoir 1200. Both the glue reservoir 1200 and the nozzle 1300 are disposed inside the valve housing 1100, and an annular air passage 1180 is formed between the valve housing 1100 and the outer walls of the glue reservoir 1200 and the nozzle 1300. An air outlet 1 is provided on the valve housing 1100 corresponding to the position of the nozzle 1300. 130, the jet nozzle 1130 connects to the annular air passage 1180 and the outside atmosphere, and allows glue to be sprayed out through the glue spray nozzle 1310 and the jet nozzle 1130; the valve stem 1400 is also disposed inside the valve housing 1100, and slidably passes through the glue reservoir tube 1200, with one end extending into the nozzle 1300, so that the glue spray nozzle 1310 can be opened or closed by driving the valve stem 1400 to slide; the valve housing 1100 has a control air chamber 1140 formed at the end opposite to the jet nozzle 1130, and the end of the valve stem 1400 opposite to the glue spray nozzle 1310 extends into the control air chamber 1140, and the second piston 1500... The control air chamber 1140 is disposed within the control air chamber 1140 and connected to the valve stem 1400. The second piston 1500 divides the control air chamber 1140 into a first variable air chamber 1441 and a second variable air chamber 1142. One end of the return spring 1600 abuts against the side of the second piston 1500 away from the nozzle 1310, and the other end abuts against the inner wall of the second variable air chamber 1142 (formed by adjusting bolts). It provides an elastic restoring force to move the second piston 1500 and the valve stem 1400 towards the nozzle 1310; that is, the return spring 1600 keeps the valve stem 1400 closed. At the position of the glue spray nozzle 1310; the first connecting part 1110 and the second connecting part 1120 are respectively provided on opposite sides of the valve housing 1100, that is, the air inlet and the glue inlet 1114 are both provided on the valve housing 1100, and the air inlet includes the first air inlet 1122 and the second air inlet 1123. The valve housing 1100 has a glue channel 1150 connecting the glue storage tube 1200 and the glue inlet 1114, a first airflow channel 1160 connecting the first air inlet 1122 and the first variable air chamber 1441, and a second airflow channel 1170 connecting the second air inlet 1123 and the annular air passage 1180.When the valve body 1000 is in operation, glue is injected into the glue storage tube 1200 and nozzle 1300 through the glue inlet 1114 and glue channel 1150. Compressed air is introduced into the first variable air chamber 1441 through the first air inlet 1122 and first airflow channel 1160, which drives the piston to move the valve stem 1400 away from the glue spray nozzle 1310, thereby opening the glue spray nozzle 1310 to spray glue. At the same time, compressed air is introduced into the annular air passage 1180 through the second air inlet 1123 and second airflow channel 1170, and the air is sprayed out through the jet nozzle 1130 surrounding the glue spray nozzle 1310, so that the sprayed glue is atomized and diffused by the high-speed sprayed airflow, thereby achieving glue coating.

[0061] It should be understood that, since the valve body 1000 requires two compressed air paths to open the glue nozzle 1310 and diffuse the glue atomization, in some embodiments, correspondingly, the supply air path, the intake air path, and the air passage 6200 are all provided with two paths, and for ease of explanation, the two air passages 6200 are respectively named the first air passage 6210 and the second air passage 6220; at the same time, in order to achieve the rotation of the second connecting part 1120 relative to the second connecting arm 6500 while avoiding affecting the intake of the two compressed air paths, in some embodiments, refer to Figures 10 to 14 The second connecting arm 6500 is provided with an adapter hole 6510, and the second connecting part 1120 is provided with a second half-shaft body 1121 that is inserted into the adapter hole 6510. A first annular cavity 6511 and a second annular cavity 6512 are formed between the second half-shaft body 1121 and the hole wall of the adapter hole 6510, and a first air inlet 1122 and a second air inlet 1123 are both provided on the second half-shaft body 1121; wherein, the second end of the first air passage 6210 and the first air inlet 1122 are both connected to the first annular cavity 6511, and the second end of the second air passage 6220 and the second... The air inlets 1123 are all connected to the second annular cavity 6512. Since the second end of the first air passage 6210 is connected to the first air inlet 1122 through the first annular cavity 6511, and the second end of the second air passage 6220 is connected to the second air inlet 1123 through the second annular cavity 6512, during the rotation of the second half-shaft 1121 in the transition hole 6510, the second end of the first air passage 6210 will always be connected to the first air inlet 1122, and the second end of the second air passage 6220 will always be connected to the second air inlet 1123.

[0062] It is understood that, in order to drive the valve body 1000 to rotate about the rotating frame 6000, in some embodiments, reference is made to... Figure 13 and 15The coating valve also includes a tilting drive mechanism 8000. One end of the second half-shaft 1121 extends to the side of the second connecting arm 6500 opposite to the first connecting arm 6400 and is connected to the tilting drive mechanism 8000. The tilting drive mechanism 8000 is disposed on the rotating frame 6000 and is used to drive the valve body 1000 to rotate relative to the rotating frame 6000.

[0063] It should be understood that the tilting drive mechanism 8000 can be selected in various different forms. For example, the tilting drive mechanism 8000 can be selected by using a drive motor with a coupling directly connected to the second half-shaft 1121, or it can be selected by using a gear mechanism driven by a drive motor with the output gear connected to the second half-shaft 1121, or it can be selected by using a slider linkage mechanism driven by a linear actuator, etc.; for example, referring to Figure 15 In one embodiment, the tilting drive mechanism 8000 includes a first connecting rod 8100, a second connecting rod 8200, a sliding pin 8300, and a linear actuator (not shown in the figures). The first connecting rod 8100 is connected to the second half-shaft 1121. One end of the second connecting rod 8200 is hinged to the first connecting rod 8100. The sliding pin 8300 is rotatably inserted through the other end of the second connecting rod 8200. A sliding groove 6530 is provided on the second connecting arm 6500. The sliding pin 8300 is partially slidably disposed in the sliding groove 6530. The linear actuator is disposed on the second connecting arm 6500, and the driving part of the linear actuator is connected to the sliding pin 8300 and is used to drive the sliding pin 8300 to slide in the sliding groove 6530. In turn, the second half-shaft 1121 is rotated through the second connecting rod 8200 and the first connecting rod 8100 to realize the rotation of the valve body 1000. It should be understood that the linear actuator can be any form of linear drive device, such as a pneumatic actuator, an electromagnetic actuator, or a linear motor, without any specific restrictions.

[0064] It is understandable that, in order to avoid the first link 8100 and the second link 8200 protruding beyond the second connecting arm 6500 and affecting the neatness of the appearance, in some embodiments, reference is made to... Figure 15 The second connecting arm 6500 has a receiving groove 6520 on the side opposite to the first connecting arm 6400, and both the first connecting rod 8100 and the second connecting rod 8200 are received in the receiving groove 6520; at the same time, in order to avoid interference and collision between the valve body 1000 and the rotating frame 6000 or the electric slip ring 7000 during the rotation of the valve body 1000, in one embodiment, refer to Figure 15The groove wall of the receiving groove 6520 includes a first limiting wall 6521 and a second limiting wall 6522. The first limiting wall 6521 and the second limiting wall 6522 are both disposed on the rotation path of the first connecting rod 8100 and are used to limit the rotation angle of the first connecting rod 8100. Specifically, the first connecting rod 8100 includes a first part and a second part located on both sides of the second half-shaft 1121. The first limiting wall 6521 and the second limiting wall 6522 are disposed adjacent to each other and are respectively used to abut against the first part and the second part to limit the first connecting rod 8100 in two different directions of forward rotation and reverse rotation.

[0065] It should be understood that, in one embodiment, reference is made to... Figure 12 and Figure 14 Similarly, the rotating frame 6000 is also provided with a mounting cavity 6600 that communicates with the sliding groove 6530, and the linear actuator is installed in the mounting cavity 6600 to avoid the linear actuator being exposed on the rotating frame 6000 and affecting the neatness of the appearance; for example, specifically, the mounting cavity 6600 is formed on the flange 6300 and the second connecting arm 6500, and when the linear actuator is a pneumatic push rod, the pneumatic push rod may include a push rod and a third piston. The third piston divides the mounting cavity 6600 into a third variable air chamber and a third variable air chamber. One end of the push rod is connected to the third piston, and the sliding pin 8300 is rotatably connected to one end of the push rod. Thus, by breathing into or venting from the third variable air chamber, the sliding pin 8300 can be driven to slide.

[0066] It is understood that, in some embodiments, to facilitate connection between the glue supply device and the compressed gas supply device, the stator portion 7100 is sleeved on the outside of the rotor portion 7200; simultaneously, to facilitate driving the rotor portion 7200 to rotate relative to the stator portion 7100, refer to... Figure 2 and Figure 3 The coating valve also includes a rotor drive mechanism 9000, which includes a first gear 9100, a second gear 9200, and a rotary driver 9300. The first gear 9100 is disposed on the outer periphery of the rotor portion 7200, and the stator portion 7100 is provided with a clearance groove that allows the first gear 9100 to partially protrude. The second gear 9200 meshes with the first gear 9100. The rotary driver 9300 is connected to the second gear 9200 and is used to drive the second gear 9200 to rotate, thereby driving the first gear 9100 and the rotor portion 7200 to rotate through the second gear 9200.

[0067] It should be understood that, in one embodiment, reference is made to... Figure 1The coating valve also includes a protective cover 2100 covering the outside of the electric slip ring 7000, and the outside of the protective cover 2100 is also connected to a glue storage cylinder 2200 and an air inlet connector 2300. The bottom of the glue storage cylinder 2200 is connected to the glue supply flow path on the stator 7100 through a pipeline, and the air inlet connector 2300 is connected to the air supply flow path on the stator 7100 and is connected to an external compressed air supply device.
