Description

Technical Field

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

[0002] In related technologies, a coating valve includes a valve body, an adhesive inlet pipe, an air inlet pipe, a first rotary drive structure, and a second rotary drive structure. The valve body has an adhesive inlet, an air inlet, and a spray nozzle. The adhesive inlet pipe and the air inlet pipe are externally connected to the valve body and respectively connect to the adhesive inlet and the air inlet, thereby enabling pneumatic control of the valve body by supplying adhesive to the valve body through the adhesive inlet pipe and delivering compressed air to the valve body through the air inlet pipe. The spray nozzle is used to spray adhesive. Simultaneously, the valve body is rotatably connected to the second rotary drive structure and can rotate around the second rotary drive structure under its drive. The first rotary drive structure is connected to the first rotary drive structure and can drive the valve body to rotate around the first axis under the drive of the first rotary drive structure. Although this type of coating valve can change the orientation of the spray nozzle by means of the first rotary drive structure and the second rotary drive structure, thereby changing the spray direction to improve the versatility of the coating valve, during the rotation of the valve body, the glue inlet pipe and air inlet pipe connected to the valve body need to rotate with the valve body at all times. Therefore, problems such as pipe bending and winding are prone to occur, which will affect the normal operation of the coating valve. Its safety and reliability are low. Summary of the Invention

[0003] This invention aims to at least solve 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 direction of adhesive spraying, but also has higher safety and reliability.

[0004] The coating valve of this invention includes an electric slip ring, a rotating frame, and a valve body. The electric slip ring includes a stator and a rotor. The stator is fixedly disposed and has an internal glue supply path for connecting to a glue supply device and a gas supply path for connecting to a compressed gas supply device. The rotor is rotatably connected to the stator and has an internal glue inlet path for connecting to the glue supply path and a gas inlet path for connecting to the gas supply path. The rotating frame is connected to one end of the rotor and has a glue channel and a gas channel. The first end of the glue channel is connected to the glue inlet path, and the first end of the gas channel is connected to the gas inlet path. The valve body has a rotating connection and a glue nozzle and is rotatably connected to the rotating frame through the rotating connection. The rotation axis of the valve body about the rotating frame is perpendicular to the rotation axis of the rotor about the stator. The rotating connection has a glue inlet and a gas inlet. The glue inlet is connected to the second end of the glue channel, and the gas inlet is connected to the second end of the gas channel.

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

[0006] Because the valve body is rotatably connected to the rotating frame, which is connected to the rotor of the electric slip ring, and the rotor is rotatably connected to the stator, and the axis of rotation of the valve body about the rotating frame is perpendicular to the axis of rotation of the rotor about the stator, the valve body can rotate about two mutually perpendicular axes by means of the electric slip ring and the rotating frame to change the orientation of the glue nozzle and adjust the glue spraying angle. Simultaneously, because the stator has a glue supply path and a gas supply path, the rotor has a glue inlet path and a gas inlet path, and the rotating frame has a glue channel and a gas channel, the glue... Water can enter the valve body sequentially through the glue supply path, glue inlet path, glue channel, and glue inlet. Compressed gas that controls the valve body can enter the valve body sequentially through the air supply path, air inlet path, air channel, and air inlet. Therefore, there is no need to install external pipelines between the valve body, rotating frame, and electric slip ring to complete the glue or air intake. Thus, when the valve body is driven to rotate around the two mutually perpendicular axes, there will be no problem with normal glue spraying due to the bending or winding of external pipelines. This makes the coating valve safer and more reliable, and also cleaner and more aesthetically pleasing overall.

Detailed Implementation

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] The following is for reference only. Figure 1 To be continued Figure 9 This describes the coating valve according to an embodiment of the present invention.

[0034] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the coated valve includes an electric slip ring 7000, a rotating frame 6000, and a valve body 1000.

[0035] Among them, reference Figure 2 , Figure 3 The electrical slip ring 7000 includes a stator 7100 and a rotor 7200. The stator 7100 is fixedly installed, and the rotor 7200 is rotatably connected to the stator 7100. The rotating frame 6000 is connected to one end of the rotor 7200.

[0036] Reference Figures 3 to 5 The valve body 1000 is provided with a glue spray nozzle 1310 for spraying glue and 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, by means of the electric slip ring 7000 and the rotating frame 6000, the valve body 1000 can be rotated about two mutually perpendicular axes to adjust the orientation of the glue spray nozzle 1310 and change the glue spraying angle, thereby expanding the working space range of the coating valve and improving the versatility of the coating valve.

[0037] The stator section 7100 also has an internal connection for connecting the glue supply device (e.g. Figure 1 The glue storage cylinder 2200 has a glue supply path (not shown in the figure) 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; meanwhile, referring to Figure 3 , Figure 6 and Figure 8 The rotating frame 6000 is connected to one end of the rotor 7200, and the rotating frame 6000 is provided with an adhesive flow channel 6100 and an air channel 6200, wherein the first end of the adhesive flow channel 6100 is connected to the adhesive inlet path, and the first end of the air channel 6200 is connected to the air inlet path; and refer to Figures 4 to 8The valve body 1000 is also provided with a rotating connection part, which can be rotatably connected to the rotating frame 6000. The rotating connection part is provided with a glue inlet 1114 and an air inlet. The glue inlet 1114 is connected to the second end of the glue flow channel 6100, and the air inlet is connected to the second end of the air channel 6200.

[0038] Understandably, 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 sequentially 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 sequentially 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. The safety and reliability are higher, and the coating valve is also cleaner and more aesthetically pleasing overall.

[0039] It is understandable 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... Figures 4 to 8 The rotating frame 6000 includes a first connecting arm 6400 and a second connecting arm 6500, which are located on both sides of the valve body 1000. The rotating connection includes a first connecting portion 1110 and a second connecting portion 1120 respectively located 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 installation stability of the valve body 1000. For stability; and to allow the glue and compressed air to enter the valve body 1000 from both sides respectively; wherein, the second end of the glue flow channel 6100 is provided at the first connecting arm 6400, and the glue inlet 1114 is correspondingly provided at the first connecting part 1110, so that the glue 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.

[0040] It is understandable that, in order to achieve glue injection while avoiding affecting the rotation of the first connecting portion 1110 relative to the first connecting arm 6400, in some embodiments, reference is made to... Figures 4 to 8A 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 8 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.

[0041] 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.

[0042] It should be understood that, in some of these embodiments, reference is made to... Figure 4 and Figure 5The 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 spray nozzle 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. The valve housing 1100 has a spray nozzle positioned corresponding to the nozzle 1300. Air inlet 1130 connects to annular air passage 1180 and the outside atmosphere, allowing glue to be sprayed out through spray nozzle 1310 and air inlet 1130; valve stem 1400 is also disposed inside valve housing 1100 and slidably passes through glue reservoir 1200, with one end extending into nozzle 1300, so that spray nozzle 1310 can be opened or closed by driving valve stem 1400 to slide; valve housing 1100 has a control air chamber 1140 formed at the end opposite to air inlet 1130, and the end of valve stem 1400 opposite to spray nozzle 1310 extends into control air chamber 1140, second live The stopper 1500 is disposed within the control air chamber 1140 and connected to the valve stem 1400. Simultaneously, 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. 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 nozzle. At position 1310; the first connecting part 1110 and the second connecting part 1120 are respectively disposed on opposite sides of the valve housing 1100, that is, the air inlet and the glue inlet 1114 are both disposed 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.

[0043] 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 5 to 8 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. The first air inlet 1122 and the second air inlet 1123 are both provided on the second half-shaft body 1121. The second end of the first air passage 6210 and the first air inlet 6512 are both connected to the first annular cavity 6511, and the second end of the second air passage 6220 and the first air inlet 6512 are both connected to the first annular cavity 6511. Both air inlets 1123 are 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.

[0044] 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 7 and Figure 9The 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.

[0045] 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 9 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. 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.

[0046] 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 9 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 9The 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.
