DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0032] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] See also Figure 1 and Figure 2 The embodiment of the present application provides a spraying device, including a base 11, a material storage assembly and a spraying assembly. The base 11 includes a first side 15 arranged at the top and a second side 16 arranged at the bottom.

[0034] The material storage assembly includes a material chamber 21, a control ring 22 and a plurality of plunger components 23. The material chamber 21 is arranged on the first side 15. A discharge channel 29 is arranged at the bottom of the material chamber 21. The control ring 22 is rotatably connected to the base 11. The rotation axis of the control ring 22 extends in the vertical direction. The plunger component 23 is movably connected to the control ring 22 in the vertical direction. The material chamber 21 is provided with a supporting portion 24. A first supporting slope is arranged at the bottom of the supporting portion 24. The first supporting slope is configured so that the plunger component 23 passes through the supporting portion 24 when rotating with the control ring 22, and the plunger component 23 abuts against the first supporting slope to make the plunger component 23 move toward the second side 16.

[0035] The vertical direction can be Figure 1 The direction shown by the Z axis.

[0036] The material chamber 21 is used to contain the mixed material to be sprayed.

[0037] The specific structure of the rotational connection between the control ring 22 and the base 11 and the driving structure of the control ring 22 can be selected from existing structures and will not be described in detail here.

[0038] The control ring 22 may be provided with a sliding hole, and the plunger component 23 is inserted into the sliding hole, so that the plunger component 23 can be movably connected to the control ring 22 .

[0039] A spring may be provided between the plunger component 23 and the control ring 22 , and the spring is used to provide an elastic force for moving the plunger component 23 in a direction away from the second side 16 .

[0040] The projection of the first abutment slope on the horizontal plane can be an arcuate surface 221, and the projection of the first abutment slope on the vertical plane can be an inclined surface gradually approaching the first side 15. This arrangement increases the contact time between the plunger component 23 and the first abutment slope, and enables the plunger component 23 to move toward the second side 16 under the action of the first abutment slope.

[0041] The spray assembly includes a discharge barrel 31, a blocking portion 33 and a spray component. The discharge barrel 31 is rotatably connected to the second side 16. The rotation axis of the discharge barrel 31 extends in the vertical direction. Around the circumference of the discharge barrel 31, the discharge barrel 31 is provided with a plurality of discharge through holes 32. The base 11 is provided with a first through hole 12 and a second through hole 14 connected to the first side 15 and the second side 16. The discharge channel 29 is connected to the first through hole 12. The first abutting inclined surface is provided corresponding to the second through hole 14. The blocking portion 33 is provided at a position away from the second through hole 14 at the discharge barrel 31. One side of the two sides 16 is used to block the port at the bottom of the multiple discharge through holes 32. The blocking portion 33 is provided with a notch 34. The second through hole 14 is provided corresponding to the notch 34. The inlet of the spraying component is provided below the second through hole 14. The discharge barrel 31 includes a first state and a second state. In the first state, one of the multiple discharge through holes 32 is opposite to the first through hole 12. In the second state, one of the multiple discharge through holes 32 is opposite to the second through hole 14. The plunger component 23 is inserted into the discharge through hole 32 via the second through hole 14.

[0042] The specific rotational connection structure between the discharge barrel 31 and the second side 16 of the base 11 and the driving structure of the discharge barrel 31 can be selected from existing structures and will not be described in detail here.

[0043] The plurality of discharge holes 32 are used to accommodate the mixed material.

[0044] The side of the discharge barrel 31 close to the second side 16 can be against the base 11, so that the base 11 can close the end of the discharge through hole 32 close to the base 11, that is, when the discharge through hole 32 is misaligned with the first through hole 12 and the second through hole 14, the end of the discharge through hole 32 close to the base 11 is covered by the base 11. Of course, other components can also be provided on the base 11 to achieve the purpose of covering the end of the discharge through hole 32.

[0045] The blocking portion 33 enables the bottom port of the discharge through hole 32 to be closed, thereby preventing the mixed material entering the discharge through hole 32 from leaking out from the bottom port of the discharge through hole 32 .

[0046] The notch 34 of the blocking portion 33 ensures that when the discharge barrel 31 rotates to a certain angle, the discharge hole 32 facing the notch 34 is no longer blocked by the blocking portion 33 , and the mixed material in the discharge hole 32 can leak out.

[0047] The switching between the first state and the second state of the discharge barrel 31 is achieved by driving the discharge barrel 31 to rotate. Specifically, when the discharge barrel 31 rotates to a certain angle, a certain discharge through hole 32 corresponds to the first through hole 12 of the base 11. At this time, the mixed material in the material cavity 21 can enter the discharge through hole 32 through the first through hole 12. Then the discharge barrel 31 continues to rotate until the discharge barrel 31 switches to the second state. At this time, the discharge through hole 32 containing the mixed material rotates to the notch 34 of the sealing portion 33, so that the mixed material can be discharged.

[0048] Furthermore, by properly controlling the rotation of the discharge barrel 31 and the control ring 22, when in the second state, the plunger component 23 synchronously enters the discharge through hole 32 from the second through hole 14, so that the mixed material can be pushed out through the plunger component 23 and then enter the spraying component.

[0049] The spraying components are used to achieve the purpose of spraying the mixture.

[0050] In the embodiment of the present application, since the volume of the discharge hole 32 is constant, the volume of the mixed material entering the discharge hole 32 is also constant. By controlling the rotation of the discharge cylinder 31 and the control ring 22, the discharge amount of the mixed material per unit time can be controlled, thereby achieving the purpose of quantitative supply of the mixed material. Figure 2 and Fig. 9 In some embodiments, the spraying component includes a discharge portion 41 , which is disposed at the notch 34 , and a discharge channel 42 is disposed at the discharge portion 41 , and an inlet of the discharge channel 42 is disposed below the second through hole 14 .

[0051] The inlet of the discharge channel 42 is arranged below the second through hole 14 . When the discharge barrel 31 rotates until the discharge through hole 32 containing the mixed material moves to the notch 34 , the mixed material in the discharge through hole 32 is discharged into the discharge channel 42 .

[0052] See also Figure 2 In some embodiments, the spraying component further includes a spraying channel 51 and an air source channel 52. The spraying channel 51 is communicated with the exhaust channel 42, and the air source channel 52 is communicated with the spraying channel 51.

[0053] The spraying channel 51 is used for performing the spraying operation.

[0054] The spraying channel 51 is connected to the discharge channel 42 , so that the mixed material in the discharge channel 42 can enter the spraying channel 51 .

[0055] The gas source channel 52 is used to input gas into the spraying channel 51, so that the mixed material has a certain initial velocity when discharged, thereby achieving the purpose of spraying.

[0056] See also Figure 2 In some embodiments, the material chamber 21 is movably connected to the base 11 along the vertical direction, the base 11 is provided with a connecting channel 13, the connecting channel 13 is connected to the first through hole 12, the discharge channel 29 is movably connected to the connecting channel 13, and an elastic member 210 is provided between the material chamber 21 and the base 11.

[0057] The elastic member 210 may be a spring, and the elastic member 210 is used to provide an elastic force to move the material cavity 21 away from the first side 15 , ie, to make the material cavity 21 rise.

[0058] The specific manner in which the material chamber 21 and the base 11 are movably connected can be selected from the existing structures and will not be described in detail here.

[0059] The discharge channel 29 is connected to the first through hole 12 through the connecting channel 13 . Compared with directly connecting the discharge channel 29 to the first through hole 12 , the contact area is larger and the installation is more convenient.

[0060] The material chamber 21 is movably connected to the base 11. As the material chamber 21 continuously discharges material, under the action of the elastic restoring force of the elastic member 210, the material chamber 21 gradually moves away from the first side 15, and then the abutting portion 24 also gradually moves away from the first side 15. On the one hand, by observing the position of the material chamber 21, it can play a prompting role, and can timely remind the operator to replenish material. On the other hand, when the abutting portion 24 moves away from the first side 15, the length of the plunger component 23 inserted into the discharge through hole is reduced, which can reduce the wear of the plunger component 23 and increase the service life of the plunger component 23.

[0061] See also Figure 2 In some embodiments, the discharge channel 29 is inserted into the connecting channel 13 .

[0062] The discharge channel 29 is inserted into the connecting channel 13 so that the discharge channel 29 can be connected to the connecting channel 13 and move relative to the connecting channel 13, thereby reducing the risk of disconnection between the discharge channel 29 and the connecting channel 13 when the material cavity 21 moves.

[0063] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 In some embodiments, the plunger component 23 includes a main body 26, a rotating portion 27 and a moving portion 28. The main body 26 is movably connected to the control ring 22 in the vertical direction. The rotating portion 27 is rotatably connected to the main body 26, and the rotation axis of the rotating portion 27 extends in the vertical direction. The rotating portion 27 is provided with a toggle portion 213, and the base 11 is provided with a second abutting inclined surface 215. The second abutting inclined surface 215 is configured so that when the discharge barrel 31 is in the second state, the toggle portion 213 abuts against the second abutting inclined surface 215 to rotate the rotating portion 27.

[0064] The specific structure of the rotational connection between the rotating part 27 and the main body 26 can be selected from existing structures and will not be described in detail here.

[0065] Along the rotation direction of the control ring 22 , the second abutting inclined surface 215 may gradually approach the control ring 22 .

[0066] When the control ring 22 rotates and the plunger component 23 passes the second abutting inclined surface 215 , the toggle portion 213 can abut against the second abutting inclined surface 215 , so that the rotating portion 27 can rotate under the action of the second abutting inclined surface 215 .

[0067] In the vertical direction, the movable part 28 is movably connected to the main body 26, and the movable part 28 is arranged on the side of the rotating part 27 close to the first side 15. A plurality of convex teeth 211 are respectively arranged on the opposite sides of the movable part 28 and the rotating part 27. The plurality of convex teeth 211 are arranged around the circumference of the rotation axis of the rotating part 27, and the convex teeth 211 of the movable part 28 are meshed with the convex teeth 211 of the rotating part 27.

[0068] The specific structure of the movable connection between the moving part 28 and the main body 26 can be selected from existing structures, which will not be repeated here. It should be noted that the moving part 28 can only move along the rotation axis of the rotating part 27, but cannot rotate relative to the main body 26.

[0069] A spring may be provided between the moving part 28 and the main body 26 to provide an elastic force for moving the moving part 28 toward the rotating part 27 . A spring may also be provided between the rotating part 27 and the main body 26 to reset the rotating part 27 .

[0070] The contact surface between the protruding teeth 211 of the movable part 28 and the protruding teeth 211 of the rotating part 27 can be an inclined surface, so that when the rotating part 27 rotates, the protruding teeth 211 of the movable part 28 and the rotating part 27 can be misaligned, thereby allowing the movable part 28 to move away from the rotating part 27 under the action of the protruding teeth 211.

[0071] When the rotating part 27 rotates, under the action of the convex teeth 211, the moving part 28 moves away from the rotating part 27, that is, the moving part 28 plays a compensating role. Specifically, when discharging materials, only the abutment part 24 drives the main body 26 to push the mixed material, and the discharge effect on the mixed material is limited. Therefore, after the main body 26 is inserted into the discharge through hole 32, the rotating part 27 drives the moving part 28 to further push the material, thereby increasing the discharge effect on the mixed material.

[0072] It should be noted that when the material chamber 21 rises, the material in the material chamber 21 is insufficient, so the amount of mixed material that can enter the discharge hole 32 is small, and the fluidity of the mixed material is good. Therefore, although the length of the plunger component 23 inserted into the discharge hole 32 is reduced, the discharge effect can still be met. However, there is a risk of error in the discharge amount at this time. This problem can be solved by setting an error threshold, that is, when the error of the discharge amount is within the allowable range, the spraying can continue. If it exceeds the threshold, the material is replenished in time to eliminate the error.

[0073] See also Figure 2 and Figure 3 In some embodiments, the main body 26 is provided with a limiting cavity, and an opening is provided on the side of the limiting cavity close to the first side 15. The rotating part 27 and the moving part 28 are inserted into the limiting cavity through the opening of the limiting cavity. The main body 26 is provided with a limiting channel 222, and the toggle part 213 is connected to the rotating part 27 through the limiting channel 222.

[0074] The moving part 28 and the rotating part 27 are accommodated in the limiting cavity. On the one hand, the moving part 28 and the rotating part 27 can be protected by the main body 26. On the other hand, under the action of the limiting cavity, the moving part 28 can be moved relative to the main body 26.

[0075] See also Figure 3 , Figure 4 , Figure 7 and Figure 8In some embodiments, the rotating portion 27 is provided with an air inlet channel 212, the moving portion 28 is provided with an air outlet channel 219, the toggle portion 213 is provided with an air channel 214, the air channel 214 is communicated with the air inlet channel 212, the toggle portion 213 is movably connected to the rotating portion 27, the moving direction of the toggle portion 213 is perpendicular to the rotation axis of the rotating portion 27, the side of the toggle portion 213 away from the rotating portion 27 is a cylindrical structure 220 whose axis is parallel to the rotation axis of the rotating portion 27, the inlet of the air channel 214 is arranged on the side wall surface of the cylindrical structure 220, the base 11 is provided with an exhaust end 216, the exhaust end 216 is arranged above the second abutting inclined surface 215, the exhaust end 216 includes a curved surface 221, the exhaust end 216 is provided with an exhaust channel 217, and the outlet of the exhaust channel 217 is arranged on the curved surface 221.

[0076] The inlet of the outlet channel 219 of the moving part 28 can be arranged on the side of the moving part 28 facing the rotating part 27, and the outlet can be arranged on the side close to the discharge through hole 32. The outlet of the inlet channel 212 of the rotating part 27 can be arranged on the side of the rotating part 27 facing the moving part 28, so that the inlet channel 212 can be connected with the outlet channel 219. Under the action of the chamber surrounded by the limiting cavity, the gas in the inlet channel 212 can enter the outlet channel 219 and be discharged from the outlet of the outlet channel 219.

[0077] The toggle portion 213 is movably connected to the rotating portion 27. The advantage of such a configuration is that when the toggle portion 213 cooperates with the second abutting inclined surface 215, under the action of the friction force, the toggle portion 213 tends to move away from the rotating portion 27. At this time, the force arm of the toggle portion 213 applying torque to the rotating portion 27 increases, making it easier to drive the rotating portion 27 to rotate.

[0078] A spring may be provided between the toggle portion 213 and the rotating portion 27 so that the toggle portion 213 can be reset.

[0079] When the toggle portion 213 moves relative to the rotating portion 27, the airway 214 and the air inlet channel 212 remain connected. The connection method between the airway 214 and the air inlet channel 212 can be selected from the existing structure. For example, the two can be connected through a deformable soft channel.

[0080] When the material chamber 21 rises to a certain position, the toggle portion 213 is away from the second abutting slope 215 . At this time, when the control ring 22 rotates, the toggle portion 213 cannot contact the second abutting slope 215 , but contacts the exhaust end 216 above the second abutting slope 215 .

[0081] The exhaust channel 217 of the exhaust end 216 is used to exhaust gas. The exhaust channel 217 can be connected to an air source device 218 such as an air compressor, and the exhaust of the exhaust channel 217 can be controlled by the air source device 218.

[0082] By properly setting the position of the exhaust end 216 relative to the toggle portion 213, when the toggle portion 213 passes through the exhaust end 216, the cylindrical structure 220 of the toggle portion 213 can be against the arc surface 221 of the exhaust end 216, and the two are in full contact. At this time, the outlet of the exhaust channel 217 and the inlet of the air channel 214 are connected, and the gas in the exhaust channel 217 can enter the air channel 214 and then enter the air inlet channel 212 of the rotating portion 27. In addition, since the toggle portion 213 is movably connected to the rotating portion 27, when the plunger component 23 moves further, within a certain range, the cylindrical structure 220 rotates relative to the arc surface 221, that is, at this time, the exhaust channel 217 and the air channel 214 can remain connected, which increases the time that the exhaust channel 217 and the air channel 214 can be connected, thereby increasing the amount of gas that can be input into the air inlet channel 212. Afterwards, the plunger component 23 moves further along with the control ring 22 , at which time the cylindrical structure 220 and the arc-shaped surface 221 are separated, and the exhaust passage 217 can stop exhausting.

[0083] The gas in the air inlet channel 212 can enter the air outlet channel 219 of the movable part 28, and then enter the exhaust hole. Under the action of the gas, the mixed material in the discharge hole 32 can be discharged. On the one hand, the discharge hole 32 can be cleaned after the spraying is completed. On the other hand, when the length of the plunger component 23 inserted into the discharge hole 32 is reduced, gas can be input into the discharge hole 32 to assist the discharge.

[0084] Furthermore, when the toggle portion 213 passes through the exhaust end 216, the rotating portion 27 rotates under the action of the convex tooth 211, so that the movable portion 28 can move away from the rotating portion 27, so that a certain gap can exist between the rotating portion 27 and the movable portion 28, and the gap can store part of the gas, so that when the toggle portion 213 and the exhaust end 216 are separated, the gas outlet channel 219 can still maintain exhaust for a certain period of time, and the movable portion 28 can also be inserted into the exhaust through hole, thereby ensuring that the gas can be input into the discharge through hole 32.

[0085] It should be noted that, due to the cross-sectional viewing angle, the air inlet channel 212 and the air outlet channel 219 in the figure only show partial structures.

[0086] In some embodiments, the axis of the inlet section of the air inlet channel 212 is perpendicular to the rotation axis of the rotating portion 27 , and the shifting portion 213 is inserted into the inlet section of the air inlet channel 212 .

[0087] The toggle part 213 is inserted into the inlet section of the air inlet passage 212, so that the toggle part 213 can move relative to the rotating part 27 while the air passage 214 of the toggle part 213 can remain connected to the air inlet passage 212 of the rotating part 27. The sealing structure between the toggle part 213 and the rotating part 27 can be selected from existing structures.

[0088] See also Figure 7 In some embodiments, along the radial direction of the rotation circle of the control ring 22, ribs are provided on both sides of the first abutting inclined surface.

[0089] The retaining edge serves to limit the main body 26 .

[0090] The retaining edge can increase the matching accuracy between the main body 26 and the first abutting inclined surface, and reduce the risk of the main body 26 detaching from the first abutting inclined surface when the first abutting inclined surface applies force to the main body 26 .

[0091] The ribs can also increase the connection strength between the main body 26 and the control ring 22 . By limiting the main body 26 through the ribs, the risk of the main body 26 bending or displacing, which may damage the connection between the main body 26 and the control ring 22 , is reduced.

[0092] In the embodiment of the present application, a stirring blade 25 may be provided in the material cavity 21 according to the properties of the mixing material.

[0093] For example, for a mixture that may solidify after being stationary, a stirring blade may be provided in the material chamber 21. The stirring blade 25 is used to stir the mixture, thereby reducing the risk of the mixture solidifying.

[0094] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
