Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to a dynamically controlled spraying device. Background Art

[0002] Traditional spraying devices often use fixed spraying parameters during operation, such as spraying speed, spraying flow rate and spraying angle, etc. However, different surfaces of sprayed objects have different shapes, materials and spraying requirements. For objects with complex shapes, spraying with fixed parameters may cause paint to accumulate in recessed areas, while the convex parts are not covered with enough paint. It is difficult to ensure uniform spraying quality on the entire surface, which will affect the protective performance and appearance of the coating.

[0003] A patent application with publication number CN118341590A discloses a paint spraying device, including a base frame, a lifting frame, a material storage barrel and a spray head. The lifting frame is arranged on the upper side of the base frame and is connected to the base frame in a liftable manner. The material storage barrel is placed on the upper side of the base frame. The spray head is connected to the lifting frame. The spray head has a connecting end and a spraying end. The connecting end is connected to the material storage barrel through a pump body. When spraying the paint, the height and angle of the spray head and the surface to be sprayed can be kept stable, thereby improving the uniformity of the paint spraying and improving the construction quality.

[0004] However, this application still has some problems: the nozzle is connected to the lifting frame, and the whole nozzle rises and falls together when encountering unevenness. However, when the protrusion of the spraying surface is on one side of the base frame, the nozzle will spray unevenly as the lifting frame rises, and the paint will be thick on one side and thin on the other side of the spraying surface. The uneven spraying will not only affect the appearance quality of the coating, making its surface flatness and glossiness fail to meet the ideal requirements, but also affect the functionality of the coating. Summary of the invention

[0005] In view of the above problems in the prior art, the present invention is proposed.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: a dynamically controlled spraying device, comprising a coating assembly, including a vehicle body, a control box disposed at the end of the vehicle body, and a material barrel;

When the guide rods on both sides are lifted upward at the same time, the mounting plate and the spray head on the surface of the mounting plate are driven to lift upward together through the guide rods to control the distance from the spraying surface.

[0009] When there is a height difference between the guide rods on both sides, the guide rod at the higher position drives the adjusting component to adjust the angle of the spray head, and deflects the spray head to the opposite side of the guide rod at the higher position to control the angle between the spray head and the spraying surface.

[0013] As a preferred solution of the dynamically controlled spraying device described in the present invention, when the pushing block is squeezed and moved, the oil inside the oil cylinder enters the inside of the connecting head through the conduit, and the connecting rod moves inside the connecting head and drives the gear ring to separate from the locking ring.

[0014] As a preferred solution of the dynamically controlled spraying device described in the present invention, wherein: the outer wall of the guide rod is provided with a lifting ring and the outer wall of the lifting ring is provided with a lifting column, the adjusting component includes a fixed shell, the inner wall of the fixed shell is provided with a first rotating ring and the outer wall of the first rotating ring is provided with a first lifting rod, a first sliding groove is opened at the end of the first lifting rod and the first sliding groove is slidably matched with the lifting column, when the guide rod is lifted upward, the lifting column slides on the inner wall of the first sliding groove and drives the first rotating ring to rotate on the inner wall of the fixed shell.

[0015] As a preferred solution of the dynamically controlled spraying device described in the present invention, wherein: a placement groove is arranged inside the fixed shell for installing the first rotating ring, a limit plate is also arranged on the inner wall of the fixed shell and a transmission gear is installed in the limit plate, the transmission gear is meshed with the gear on the inner wall of the first rotating ring, and a second rotating ring is also arranged inside the fixed shell. When the first rotating ring rotates, the second rotating ring is driven by the transmission gear to rotate synchronously inside the fixed shell and in the opposite direction.

[0016] As a preferred solution of a dynamically controlled spraying device described in the present invention, a second lifting rod is arranged on the outer wall of the second rotating ring, a sliding column is arranged on the end of the second lifting rod, and the end of the sliding column extends to the inner wall of the second sliding groove opened on the end face of the vertical rod arranged on the outer wall of the connecting head and slides with it.

[0017] As a preferred solution of a dynamically controlled spraying device described in the present invention, the end face of the guide rod is provided with an oblique groove, the inner wall of the mounting plate is movably provided with a moving rod and the end of the moving rod is engaged with the oblique groove, the moving rod moves inside the moving groove provided on the inner wall of the mounting plate and a limiting ring is provided at the end of the moving rod, and the outer wall of the moving rod is also sleeved with a second elastic member.

[0019] Beneficial effects of the present invention: the present invention can automatically adjust the height and angle of the spray head when facing spraying surfaces of various complex shapes and height changes. The guide rods on both sides can quickly respond according to the ups and downs of the spraying surface. When encountering a bulge, the guide rod drives the mounting plate to rise or deflects the spray head to ensure that the spray head and the spraying surface always maintain a suitable relative position and angle, effectively avoiding the uneven spraying phenomenon caused by height and angle deviation, so that the paint can be evenly attached to areas of different heights and angles, and achieve high-quality spraying effects. The material barrel is installed above the vehicle body and is equipped with a heating component controlled by a control box and a rotating shaft and a stirring rod driven by a top motor to efficiently heat the paint, so that it melts quickly, and continues to stir during the melting process, avoiding the problem of local overheating causing the paint to deteriorate in performance or even burn.

[0020] The spray head is installed in the groove on the end face of the mounting plate, and the gear ring, fixed ring and other structures in the outer wall cavity cooperate with each other. Under normal conditions, the first elastic member pushes the gear ring to engage with the snap ring, so that the spray head maintains a stable initial angle, preventing the spray head angle from being offset due to factors such as accidental collisions during non-spraying operations or transportation. When the angle needs to be adjusted due to concave and convex surfaces during spraying operations, the guide rod and the cylinder and other components work together to accurately control the separation of the gear ring and the snap ring, realizing flexible adjustment of the spray head angle. After the adjustment is completed, it can quickly return to the locked state, ensuring the accuracy, reliability and stability of the spray head angle control. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] This is the first embodiment of the present invention, which provides a dynamically controlled spraying device.

[0039] Specifically, refer to Figure 1~Figure 4 as well as Fig. 9 , a dynamically controlled spraying device, comprising: a coating assembly 100, including a vehicle body 101, a control box 102 disposed at the end of the vehicle body 101, and a material barrel 103;

[0040] The spraying assembly 200 disposed at the end of the vehicle body 101 includes a mounting plate 201, a guide rod 202 movably disposed on the inner wall of the mounting plate 201, and an adjustment component is also disposed on the end surface of the mounting plate 201. The adjustment component is connected to the guide rod 202 and is used to control a spraying head 205 located at the end of the mounting plate 201;

[0041] The guide rods 202 are symmetrically arranged on the inner wall of the mounting plate 201. When the guide rods 202 on both sides are lifted upward at the same time, the guide rods 202 drive the mounting plate 201 and the spray head 205 on the surface of the mounting plate 201 to be lifted upward together to control the distance from the spraying surface.

[0042] When there is a height difference between the guide rods 202 on both sides, the guide rod 202 at the higher position drives the adjusting component to adjust the angle of the spray head 205, and deflects the spray head 205 to the opposite side of the guide rod 202 at the higher position to control the angle between the spray head 205 and the spraying surface.

[0043] Among them, the material barrel 103 is installed above the vehicle body 101, and the heating component inside the material barrel 103 is driven by the control box 102 on the outside to heat the paint to melt it. Then the motor on the top drives the rotating shaft 1031 inside the material barrel 103 to rotate, and the melted paint is continuously stirred inside the material barrel 103 through the stirring rod 1032 on the outer wall of the rotating shaft 1031, so that the paint can be fully mixed during the heating process to ensure uniform temperature distribution, avoid uneven heating, local overheating of the paint, resulting in reduced paint performance or even burning, and some parts may not have been completely melted, affecting the fluidity and construction quality of the paint.

[0044] The mounting plate 201 is below the front end of the vehicle body 101, guide rods 202 are provided on both sides of the mounting plate 201 and guide wheels are provided at the bottom of the guide rods 202, and the mounting plate 201 is driven by the guide wheels to move below the vehicle body 101 and pass over the spray surface to be sprayed.

[0045] The guide rods 202 on both sides move in coordination. When the height of the spraying surface changes, the guide rods 202 on both sides move as a whole, driving the mounting plate 201 to move under the vehicle body 101 to keep a distance from the spraying surface. When the spraying surface becomes uneven, a height difference appears on the guide rods 202 on both sides. The guide wheels at the protrusions cause the guide rods 202 to move upward. At the same time, the upwardly moving guide rods 202 drive the adjusting components on the surface of the mounting plate 201 to adjust the angle of the spray head 205, so that the spray head 205 is angularly offset in the direction opposite to the raised guide rods 202, so that the spray head 205 adjusts the angle with the surface to be sprayed, and the connecting pipe 2051 is fixed to the outer wall of the material barrel 103 and is connected to the spray head 205. The heated and stirred paint inside the material barrel 103 enters the spray head 205 through the connecting pipe 2051, and the paint is evenly distributed in the marked area through the spray head 205 to avoid the situation where the paint is thick on one side and thin on the other side in the lateral direction.

[0046] Specifically, refer to Figure 3 , Fig. 9 and Fig.10 The spray head 205 is arranged in a groove 2012 opened on the end surface of the mounting plate 201 and a cavity 2053 is opened on the outer wall of the spray head 205. A rotating member is arranged on the inner wall of the cavity 2053. The rotating member is connected to the adjusting member for adjusting the angle between the spray head 205 and the spraying surface.

[0047] The spray head 205 is installed inside the groove 2012 and can rotate slightly inside the groove 2012. Fig.10 As shown, the cavities 2053 are arranged on both sides of the outer wall of the spray head 205 for installing other components.

[0048] Preferably, a gear ring 2054 is provided on the inner wall of the cavity 2053, a concave surface 2055 is provided on the end face of the gear ring 2054 and a connecting rod 2056 is provided on the end facing away from the concave surface 2055, a fixing ring 2057 is installed on the outer wall of the cavity 2053 and a snap ring 2058 is provided on the inner wall of the fixing ring 2057, the end of the connecting rod 2056 extends to the outer wall of the fixing ring 2057, and a first elastic member 2059 is provided on the outer wall of the concave surface 2055 for pushing the gear ring 2054 to engage with the snap ring 2058.

[0049] Among them, the fixed ring 2057 is fixed on the outside of the cavity 2053, and the gear ring 2054 inside the cavity 2053 cooperates with the fixed ring 2057. The gear ring 2054 is pushed by the first elastic member 2059 to move outward inside the cavity 2053, and the gear ring 2054 is pushed toward the fixed ring 2057 and meshed with the locking ring 2058 on the surface of the fixed ring 2057. When not affected by external force factors, the gear ring 2054 is always locked with the fixed ring 2057. At the same time, because the fixed ring 2057 is fixed on the outer wall of the spray head 205, after the gear ring 2054 is engaged with the fixed ring 2057, the gear ring 2054 does not move inside the cavity 2053.

[0050] Better, refer to Figure 3 , Figure 4 , Fig. 9 and Fig.10 The end of the connecting rod 2056 extends to the outer wall of the fixing ring 2057 and the end is sleeved with a connecting head 206. The outer wall of the connecting head 206 is connected to a conduit 207. One end of the conduit 207 is connected to a cylinder 2071 and the cylinder 2071 is installed inside the vehicle body 101. The end of the guide rod 202 is located inside the vehicle body 101 and the end of the guide rod 202 is in contact with a pushing block 2072 located at the axis of the cylinder 2071. When the guide rod 202 is lifted upward, the end of the guide rod 202 squeezes the pushing block 2072 to move the pushing block 2072 inside the vehicle body 101. When the pushing block 2072 is squeezed and moved, the oil inside the cylinder 2071 enters the inside of the connecting head 206 through the conduit 207, and the connecting rod 2056 moves inside the connecting head 206 and drives the gear ring 2054 to separate from the locking ring 2058.

[0051] The top end of the guide rod 202 is in contact with the surface of the push block 2072. When the guide wheel below passes the protrusion, the guide rod 202 moves upward and squeezes the push block 2072, squeezing the push block 2072 backward. The oil in the oil cylinder 2071 is input into the connector 206 through the conduit 207 by squeezing the push block 2072. Fig.10 As shown, the conduit 207 and the connector 206 are connected, and the connecting rod 2056 on the surface of the gear ring 2054 passes through the fixed ring 2057 and is installed inside the connector 206. When the oil inside the oil cylinder 2071 enters the connector 206 through the conduit 207, the connecting rod 2056 will move inside the connector 206. At this time, the gear ring 2054 inside the cavity 2053 moves toward the direction of the first elastic member 2059 and squeezes the first elastic member 2059, and as the gear ring 2054 moves, it is separated from the locking ring 2058 on the surface of the fixed ring 2057. At this time, the gear ring 2054 loses the locking restriction, and the connector 206 connected to the connecting rod 2056 can move outside the spray head 205.

[0052] In summary, during use, when spraying on the spray surface, when encountering a protrusion, the guide wheel passes over the protrusion upward, driving the guide rod 202 above the guide wheel to move upward, and the top end of the guide rod 202 is located inside the vehicle body 101. When moving upward, the top inclined surface of the guide rod 202 contacts the inclined surface of the push block 2072 and squeezes the push block 2072, so that the push block 2072 moves toward the direction of the cylinder 2071. The cylinder 2071 is fixed inside the vehicle body 101 and cannot move. When the push block 2072 is squeezed and moved, the oil inside the cylinder 2071 is squeezed by the push block 2072 and enters the conduit 207, and then enters the inside of the connector 206.

[0053] The connector 206 is connected to the conduit 207 and is connected to the end of the connecting rod 2056. In the initial state, under the push of the first elastic member 2059, the gear ring 2054 is pushed toward the direction of the fixing ring 2057 and engages with the locking ring 2058. The gear ring 2054 is restricted by the fixing ring 2057 and cannot rotate inside the cavity 2053. At the same time, the connector 206 cannot rotate outside the fixing ring 2057.

[0054] When the oil is squeezed into the interior of the connecting head 206, the connecting rod 2056 is squeezed and moved inside the connecting head 206, and the gear ring 2054 inside the cavity 2053 is driven by the connecting rod 2056 to move backward and squeeze the first elastic member 2059. The gear ring 2054 moves backward and separates from the locking ring 2058. At this time, the gear ring 2054 loses the restriction of the fixing ring 2057, and the gear ring 2054 can rotate inside the cavity 2053, and the connecting head 206 can rotate outside the fixing ring 2057.

[0055] Specifically, refer to Figure 3~Figure 6 A lifting ring 2022 is sleeved on the outer wall of the guide rod 202 and a lifting column 2023 is arranged on the outer wall of the lifting ring 2022. The adjusting component includes a fixed shell 203. A first rotating ring 2034 is arranged on the inner wall of the fixed shell 203 and a first lifting rod 2036 is arranged on the outer wall of the first rotating ring 2034. A first sliding groove 2037 is opened at the end of the first lifting rod 2036 and the first sliding groove 2037 is slidably matched with the lifting column 2023. When the guide rod 202 is lifted upward, the lifting column 2023 slides on the inner wall of the first sliding groove 2037 and drives the first rotating ring 2034 to rotate on the inner wall of the fixed shell 203.

[0056] Among them, refer to Figure 3 , Figure 5 , Figure 6The fixed shell 203 is fixed on the surface of the mounting plate 201, the first rotating ring 2034 is installed on the surface of the fixed shell 203, and the first sliding groove 2037 at the end of the first lifting rod 2036 cooperates with the lifting column 2023 outside the lifting ring 2022, such as Figure 5 As shown, when the guide rod 202 is lifted upward, the lifting ring 2022 drives the lifting column 2023 upward, and the lifting column 2023 slides to the left side on the right side of the first slide groove 2037. At the same time, when the first lifting rod 2036 is lifted upward, it drives the first rotating ring 2034 to rotate inside the fixed shell 203.

[0057] Preferably, refer to Figure 5 and Figure 6 A placement groove 2031 is provided inside the fixed shell 203 for installing the first rotating ring 2034. A limit plate 2032 is also provided on the inner wall of the fixed shell 203, and a transmission gear 2033 is installed in the limit plate 2032. The transmission gear 2033 is meshed with the gear on the inner wall of the first rotating ring 2034. A second rotating ring 2035 is also provided inside the fixed shell 203. When the first rotating ring 2034 rotates, the second rotating ring 2035 is driven by the transmission gear 2033 to rotate synchronously inside the fixed shell 203 in the opposite direction.

[0058] The fixed shell 203 has two placement grooves 2031 disposed inside, and a first rotating ring 2034 and a second rotating ring 2035 are installed in the placement grooves 2031. The fixed shell 203 has two limit plates 2032 disposed inside, and each limit plate 2032 is installed with a transmission gear 2033. Figure 6 As shown, the transmission gears 2033 are arranged relatively, the middle parts are meshed and the tail parts are meshed with the gears inside the first rotating ring 2034 and the second rotating ring 2035. When the first rotating ring 2034 rotates, the transmission gear 2033 drives the second rotating ring 2035 to rotate inside the fixed shell 203 and the rotation direction is opposite to that of the first rotating ring 2034.

[0059] A second lifting rod 2038 is disposed on the outer wall of the second rotating ring 2035, and a sliding column is disposed at the end of the second lifting rod 2038. The end of the sliding column extends to the inner wall of the second sliding groove 2062 opened on the end face of the vertical rod 2061 disposed on the outer wall of the connecting head 206 and slidably cooperates therewith.

[0060] The second lifting rod 2038 is fixed to the outer wall of the second rotating ring 2035 , the vertical rod 2061 on the surface of the connecting head 206 cooperates with the second lifting rod 2038 , and the sliding column on the surface of the second lifting rod 2038 slides on the inner wall of the second sliding groove 2062 .

[0061] like Figure 4 , Figure 6 , Fig. 9As shown, when the left guide rod 202 moves upward, the end of the first lifting rod 2036 connected to the left guide rod 202 is lifted upward, the first rotating ring 2034 rotates, and the first rotating ring 2034 drives the second rotating ring 2035 to rotate in the opposite direction to the first rotating ring 2034 through the transmission gear 2033. When the end of the first lifting rod 2036 is lifted upward, the end of the second lifting rod 2038 on the surface of the second rotating ring 2035 is also lifted upward. At the same time, the sliding column at the top of the second lifting rod 2038 slides from bottom to top on the inner wall of the second slide groove 2062, while driving the vertical rod 2061 to deflect toward the left guide rod 202, so that the nozzle 2052 below deflects toward the right guide rod 202.

[0062] like Figure 3 As shown, when the left guide rod 202 moves upward, it squeezes the push block 2072 above the left guide rod 202, so that the oil inside the left oil cylinder 2071 enters the conduit 207, and enters the inside of the connecting head 206 associated with the movement of the right guide rod 202 through the conduit 207, so that the gear ring 2054 and the snap ring 2058 inside the connecting head 206 associated with the right guide rod 202 are separated, thereby releasing the restriction on the spray head 205. When the left guide rod 202 moves, it can drive the spray head 205 to rotate on the surface of the mounting plate 201.

[0063] Better, refer to Figure 3~Figure 8 A bevel groove 2021 is provided on the end face of the guide rod 202, a moving rod 204 is movably provided on the inner wall of the mounting plate 201 and the end of the moving rod 204 is engaged with the bevel groove 2021, the moving rod 204 moves inside the moving groove 2013 provided on the inner wall of the mounting plate 201 and a limiting ring 2041 is provided on the end of the moving rod 204, a second elastic member 2042 is also sleeved on the outer wall of the moving rod 204, a mounting ring 2024 is fixed to the end of the guide rod 202 and a third elastic member 2025 is provided on the end of the mounting ring 2024, and a fourth elastic member 2011 is also provided on the end of the mounting plate 201.

[0064] Among them, the moving rod 204 is movably arranged on the inner wall of the mounting plate 201, and the second elastic member 2042 is symmetrically installed on both sides of the middle limit ring 2041 of the moving rod 204. When not affected by external force, the moving rod 204 is located in the middle position of the mounting plate 201. At this time, the end positions on both sides of the moving rod 204 are located inside the inclined groove 2021 on the surface of the guide rod 202. When the guide rods 202 on both sides encounter the protrusion at the same time and move upward synchronously, the moving rod 204 drives the mounting plate 201 to move upward together with the guide rod 202 to maintain the distance between the spray head 205 and the spraying surface below. When the guide rod 202 on one side moves upward alone, the end of the moving rod 204 is squeezed, so that the moving rod 204 moves toward the guide rod 202 on the side that is not lifted, and at the same time, the nozzle 2052 will also deflect toward the guide rod 202 on the side that is not lifted.

[0065] like Figure 3 As shown, the fourth elastic member 2011 and the guide wheel located between the mounting plate 201 and the vehicle body 101 and the fifth elastic member provided in the middle of the mounting plate 201 are used to control the position of the mounting plate 201 below the vehicle body 101. At the same time, when the guide rod 202 moves upward, the third elastic member 2025 at the end of the guide rod 202 is used to push the guide rod 202 to reset.

[0066] In summary, when in use, when the guide wheels under the guide rods 202 on both sides pass through the protrusions on the spraying surface at the same time, the guide rods 202 on both sides are lifted up synchronously, and the moving rod 204 in the middle of the mounting plate 201 cooperates with the inclined grooves 2021 on the surfaces of the guide rods 202 on both sides, driving the mounting plate 201 and the guide rods 202 to move up synchronously by the same distance to ensure the distance from the spraying surface below. When the guide wheel on the left side passes through the protrusion, it drives the upper guide rod 202 upward, and the guide rod 202 on the right side does not move. At this time, the left guide rod 202 squeezes the moving rod 204 through the inclined surface of the inclined groove 2021, so that the moving rod 204 moves in the direction of the right guide rod 202. When the left guide rod 202 moves upward, it will first squeeze the upper push block 2072, so that the push block 2072 moves in the direction of the oil cylinder 2071 and squeezes the oil inside the oil cylinder 2071 to enter the inside of the guide tube 207, and then enter the inside of the connector 206 associated with the movement of the right guide rod 202 through the guide tube 207. When the left guide rod 202 moves upward, the first lifting rod 2036 drives the first rotating ring 2034 to rotate inside the fixed housing 203, and the second rotating ring 2035 is synchronously rotated and rotated through the transmission gear 2033. And the rotation direction is opposite to that of the first rotating ring 2034. The second lifting rod 2038 rotates with the second rotating ring 2035 outside the second rotating ring 2035. The top position of the second lifting rod 2038 is lifted upward and drives the vertical rod 2061 to deflect toward the left guide rod 202. At this time, the nozzle 2052 located under the spray head 205 is deflected to the right to adjust the angle with the surface to be sprayed, so as to avoid the nozzle 2052 being close to the protrusion and to avoid the situation where the paint is thick on one side and thin on the other side in the horizontal direction.
