Description

Technical Field

[0001] The present invention belongs to the technical field of paint filling, and specifically relates to a paint bucket for paint production and filling. Background Art

[0002] During the production process of paint, filling operations are required. In the past, multiple filling buckets of the same model were evenly distributed and intermittently moved through a distribution plate, and then filled one by one. When filling different models of filling buckets, separate operations were needed, and even two different production lines were required, resulting in high equipment investment and low production efficiency.

[0003] A patent with the publication number CN118004598A discloses a paint bucket for paint production and filling, including a paint bucket lid assembly. A sealing limit wheel assembly and a lifting sealing piston assembly are provided at the top of the paint bucket lid assembly. In the present invention, the sealing limit wheel assembly forms a driving wheel structure for synchronously clamping and sealing the periphery of the barrel body and the barrel lid on the paint bucket lid assembly. The lifting sealing piston assembly forms a lifting arm structure for driving the sealing limit wheel assembly to act on the paint bucket lid assembly. Moreover, when the lifting sealing piston assembly lifts and drives the sealing limit wheel assembly, the lifting sealing piston assembly causes a vacuum pumping structure synchronized with the sealing to be formed inside the paint bucket lid assembly and the paint bucket assembly. During the actual sealing of the paint bucket in the present invention, through the lifting action, rapid sealing of the paint bucket and vacuum pumping treatment inside the paint bucket can be achieved. This kind of sealing is reversible, realizing the recyclable use of the paint bucket.

[0004] Currently, in the existing technology, the filling buckets are docked in a snap-fit manner. However, the existing filling barrels are all open for filling the coating liquid. As a result, when filling the coating liquid, external air will enter the filling barrel together with the coating liquid. The moisture in the air will cause the performance of the coating liquid to decline, and the oxygen and carbon dioxide in the air will also cause chemical reactions in the chemical substances inside the coating liquid, resulting in problems such as color change and performance decline of the coating liquid.

[0005] Therefore, the present invention provides a paint bucket for paint production and filling. Summary of the Invention

The output end of the first motor is fixedly connected to a second sealing cover that is movably lapped on the top surface of the paint can. The position of the material conveying pipe is on the outer surface of the second sealing cover.

[0014] Preferably, an inward recessed groove two that is movably sleeved on the outer surface of the one-way feed port is formed on the bottom surface of the material conveying pipe.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For the paint bucket used for paint production and filling in the present invention, before filling the paint, the first sealing cover is sleeved on the top surface of the paint can, so that the second docking protrusion is docked on the inner wall surface of the docking groove, and the position of the first sealing cover can be limited. Through the docking and fitting between the first semi-circular protrusion and the second semi-circular protrusion, the first sealing cover is firmly positioned and clamped on the top surface of the paint can by the extrusion clamping force generated by the staggered docking between the first semi-circular protrusion and the second semi-circular protrusion. After the first semi-circular protrusion and the second semi-circular protrusion are docked, the sealing soft strip is used to seal the fitting between the first semi-circular protrusion and the second semi-circular protrusion, greatly reducing the effect that the air inside the paint can leaks out.

[0019] 2. A paint bucket for paint production and filling according to the present invention. After the paint can and the sealing cover one are clamped, the paint can is transported by the conveying track bar. When the paint can moves to the bottom of the sealing cover two, the swing arm swings, and the arc-shaped fitting plate on the output end of the swing arm is attached to the outer surface of the paint can, and the position of the paint can is limited. At this time, the hydraulic contraction rod is used to lower the sealing cover two, so that the sealing cover two wraps around the top surface of the sealing cover one, and the output end of the material conveying pipe penetrates into the internal of the one-way feeding port. If the output end of the material conveying pipe cannot be aligned with the one-way feeding port, the motor is used to rotate the sealing cover two, and the output end of the material conveying pipe is aligned with the one-way feeding port, and the angle of the sealing cover two is adjusted by rotation to facilitate the effective insertion and docking between the sealing cover two and the one-way feeding port;

[0020] 3. A paint bucket for paint production and filling according to the present invention. When the paint in the paint can accumulates continuously, the excess air will be discharged into the internal of the exhaust pipe along the ventilation holes. When the paint can is filled to a certain amount, the material conveying pipe and the exhaust pipe are withdrawn from the internal of the one-way feeding port. At this time, the elastic flap will reset due to its own elasticity, so that the discharge holes on the outer surface of the elastic flap are reattached to the bottom surface of the one-way feeding port. At this time, there is still paint liquid inside the elastic flap. At this time, the paint liquid will form a sealing layer between the one-way feeding port and the elastic flap, and the paint liquid in the conical cavity will also slowly fill to the top surface of the raised hard plate, so that the inside of the paint can is completely sealed, greatly isolating the outside air from entering the paint can, and greatly reducing the effect that the harmful substances in the interior decoration paint will overflow;

[0021] 4. A paint bucket for paint production and filling according to the present invention. When the exhaust pipe penetrates into the internal of the one-way feeding port, the inner recessed groove two on the bottom surface of the material conveying pipe is docked into the internal of the docking convex bar one, so that the one-way feeding port and the material conveying pipe are in a relatively closed environment, and the material conveying pipe can be effectively positioned and clamped in the one-way feeding port. When the material conveying pipe is clamped on the top surface of the one-way feeding port, the docking convex bar three at the bottom end of the exhaust pipe is docked and limited with the docking convex bar one on the top surface of the raised hard plate, and then the raised hard plate is pressed down by the length of the exhaust pipe, so that the elastic flap on the outer surface of the raised hard plate is separated from the bottom surface of the one-way feeding port, forming a concave conical cavity between the elastic flap and the one-way feeding port. At this time, the paint is filled into the material conveying pipe and the conical cavity by the feeding pipe two. The paint will accumulate in the conical cavity, and the accumulated paint will be squeezed and discharged into the paint can along the discharge holes on the outer surface of the elastic flap. Since the bottom of the raised hard plate is in an upward recessed groove at this time, the paint liquid will not block the surface of the ventilation hole before the paint in the paint can is completely filled.

Detailed Embodiments

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0034] AsFigures 1 to 4 and Figure 8 - Figure 9 As shown in Figure 9 , a paint bucket for paint production and filling according to an embodiment of the present invention includes a paint tank 12. A sealing cover 121 is movably sleeved on the top surface of the paint tank 12. A one-way feeding port 122 is provided on the top surface of the sealing cover 121 and at a side edge position. A resilient flap a2 is fixedly connected to the bottom surface of the one-way feeding port 122. A discharge hole a3 is formed on the outer surface of the resilient flap a2. A raised hard plate a4 is fixedly connected to the top surface of the discharge hole a3 and at a middle position. A ventilation hole a5 is provided on the top surface of the raised hard plate a4 and at a middle position. A docking rib a6 is fixedly connected to the top surface of the raised hard plate a4 and at the peripheral edge position of the ventilation hole a5. An indented groove a1 is formed on the top surface of the one-way feeding port 122.

[0035] When the exhaust pipe 144 is inserted into the one-way feeding port 122, it is docked with the docking rib a6 inside the indented groove 141 on the bottom surface of the conveying pipe 14, so that a relatively closed environment is formed between the one-way feeding port 122 and the conveying pipe 14, and the conveying pipe 14 can be effectively positioned and clamped inside the one-way feeding port 122. When the conveying pipe 14 is clamped on the top surface of the one-way feeding port 122, the docking rib 145 at the bottom end of the exhaust pipe 144 is docked and limited with the docking rib a6 on the top surface of the raised hard plate a4. Then, due to the length of the exhaust pipe 144, the raised hard plate a4 is pressed down, so that the resilient flap a2 on the outer surface of the raised hard plate a4 is separated from the bottom surface of the one-way feeding port 122, forming a concave conical cavity between the resilient flap a2 and the one-way feeding port 122. At this time, the paint is filled into the conveying pipe 14 and the conical cavity through the feeding pipe 142. The paint will accumulate inside the conical cavity and then be squeezed and discharged into the paint tank 12 along the discharge hole a3 on the outer surface of the resilient flap a2. Since the bottom of the raised hard plate a4 is in an upwardly recessed groove at this time, the paint liquid will not block the surface of the ventilation hole a5 before the paint in the paint tank 12 is completely filled.

[0036] As the paint in the paint can 12 continuously accumulates, the excess air will be discharged into the interior of the exhaust pipe 144 along the ventilation hole a5. When the paint can 12 is filled to a certain amount, it is withdrawn from the interior of the one-way feed port 122 in cooperation with the feed pipe 14 and the exhaust pipe 144. At this time, the elastic flap a2 will reset due to its own elasticity, causing the discharge hole a3 on the outer surface of the elastic flap a2 to fit again on the bottom surface of the one-way feed port 122. At this time, there is still paint liquid left inside the elastic flap a2, and this paint liquid will form a sealed partition layer between the one-way feed port 122 and the elastic flap a2. The paint liquid inside the conical cavity will also slowly fill to the top surface of the raised hard plate a4, making the interior of the paint can 12 completely sealed, greatly isolating the outside air from entering the paint can 12, and greatly reducing the effect of harmful substances inside the interior decoration paint from spilling out.

[0037] As Figures 1 to 2 shown, a docking rib two 124 is provided at the top edge position of the paint can 12, and a semi-circular rib one 123 is provided on the outer surface of the paint can 12 and at the top edge position. A docking groove 125 is opened on the bottom inner wall surface of the first sealing cover 121 and at the top edge position of the docking rib two 124. A semi-circular rib two 127 is fixedly connected to the four peripheral edge positions of the first sealing cover 121 and is movably lapped on the bottom outer surface of the semi-circular rib one 123. A sealing soft strip 126 is fixedly connected to the inner wall surface of the first sealing cover 121 and is movably lapped on the top outer surface of the semi-circular rib one 123.

[0038] Before filling the paint, the first sealing cover 121 is sleeved on the top surface of the paint can 12, so that the docking rib two 124 is docked to the inner wall surface of the docking groove 125, which can limit the position of the first sealing cover 121. Through the docking and fitting between the semi-circular rib one 123 and the semi-circular rib two 127, the first sealing cover 121 is firmly positioned and clamped on the top surface of the paint can 12 by the extrusion clamping force generated by the staggered docking between the semi-circular rib one 123 and the semi-circular rib two 127. After the semi-circular rib one 123 and the semi-circular rib two 127 are docked, the sealing soft strip 126 is used to seal the fit between the semi-circular rib one 123 and the semi-circular rib two 127, greatly reducing the effect of air leakage from the interior of the paint can 12.

[0039] As Figures 1 to 9As shown in the figure, an inward recessed groove two 141 is provided on the bottom surface of the material delivery pipe 14 and is movably sleeved on the outer surface of the one-way feeding port 122. The bottom surface of the material delivery pipe 14 is movably sleeved on the inner wall surface of the inward recessed groove one a1. A exhaust pipe 144 is fixedly connected to the inner wall surface of the material delivery pipe 14. A cavity 143 is provided between the outer surface of the exhaust pipe 144 and the inner wall surface of the material delivery pipe 14. A feeding pipe two 142 is fixedly connected to the outer surface of the material delivery pipe 14 and is arranged at one end of the discharge pipe 139. A docking rib three 145 is provided at the bottom end of the exhaust pipe 144 and is movably sleeved on the outer surface of the docking rib one a6. A swing arm 111 is swingably connected to the top surface of the conveying track bar 11 and at the side edge position of the support frame 13. An arc-shaped fitting plate 112 is fixedly connected to the output end of the swing arm 111 and is movably lapped on the outer surface of the paint can 12;

[0040] A conveying track bar 11 is provided on the bottom surface of the paint can 12. A support frame 13 is fixedly installed on the back surface of the conveying track bar 11. A material delivery pipe 14 is provided on the outer surface of the output end of the support frame 13. A filling box 131 is provided on the outer surface of the support frame 13. A feeding pipe one 138 is fixedly connected to the input end of the filling box 131. A discharge pipe 139 is fixedly connected to the output end of the filling box 131. A motor two 136 is provided on the back surface of the filling box 131. A limiting block is provided on the inner wall surface of the filling box 131 and at the middle position. Two groups of stirring rollers 135 are movably sleeved on the inner wall surface of the filling box 131 and at the upper and lower side edge positions of the limiting block. Limiting rods are fixedly connected to the outer surfaces of the two groups of stirring rollers 135. One end of the limiting rod extends to the outer surface of the filling box 131. The output end of the motor two 136 is fixedly installed on the surface of the limiting rod on the outer side of one group of stirring rollers 135. A transmission track 137 is movably sleeved on the outer surface of the motor two 136. The other inner wall surface of the transmission track 137 is movably sleeved on the surface of the limiting rod on the outer side of the other group of stirring rollers 135. A hydraulic contraction rod 132 is fixedly installed on the outer surface of the support frame 13. A motor one 133 is fixedly connected to the output end of the hydraulic contraction rod 132. A sealing cover two 134 is fixedly connected to the output end of the motor one 133 and is movably lapped on the top surface of the paint can 12. The position of the material delivery pipe 14 is on the outer surface of the sealing cover two 134.

[0041] Cooperate with the feeding pipe one 138 to divert the coating liquid into the interior of the filling box 131. At this time, drive the transmission track 137 and the two groups of stirring rollers 135 to rotate inside the filling box 131 through the motor two 136, perform extrusion and differentiation treatment on some relatively viscous substances inside the coating liquid, and make the discharge pipe 139 divert the coating liquid into the interior of the paint can 12;

[0042] After the paint can 12 and the first sealing cover 121 are snap - connected, the conveyor track bar 11 is used to transport the paint can 12. When the paint can 12 moves to the bottom of the second sealing cover 134, the swing arm 111 swings, and the arc - shaped fitting plate 112 at the output end of the swing arm 111 is fitted to the outer surface of the paint can 12 to limit the position of the paint can 12. At this time, the hydraulic contraction rod 132 is used to lower the second sealing cover 134, so that the second sealing cover 134 wraps around the top surface of the first sealing cover 121, and the output end of the material delivery pipe 14 penetrates into the internal of the one - way feeding port 122. If the output end of the material delivery pipe 14 and the one - way feeding port 122 are not aligned, the first motor 133 is used to rotate the second sealing cover 134, and the output end of the material delivery pipe 14 is aligned with the one - way feeding port 122. The angle of the second sealing cover 134 is adjusted by rotation to facilitate the effective insertion and docking between the second sealing cover 134 and the one - way feeding port 122.

[0043] Working principle: Before filling the paint, the first sealing cover 121 is sleeved on the top surface of the paint can 12, so that the second docking convex strip 124 is docked on the inner wall surface of the docking groove 125, which can limit the position of the first sealing cover 121. And through the docking and fitting between the first semi - circular convex strip 123 and the second semi - circular convex strip 127, using the extrusion clamping force generated by the staggered docking between the first semi - circular convex strip 123 and the second semi - circular convex strip 127, the first sealing cover 121 is firmly positioned and snap - connected on the top surface of the paint can 12. After the first semi - circular convex strip 123 and the second semi - circular convex strip 127 are docked, the sealing soft strip 126 is used to seal the fitting between the first semi - circular convex strip 123 and the second semi - circular convex strip 127, greatly reducing the effect of air leakage inside the paint can 12.

[0044] After the paint can 12 and the first sealing cover 121 are snap - connected, the conveyor track bar 11 is used to transport the paint can 12. When the paint can 12 moves to the bottom of the second sealing cover 134, the swing arm 111 swings, and the arc - shaped fitting plate 112 at the output end of the swing arm 111 is fitted to the outer surface of the paint can 12 to limit the position of the paint can 12. At this time, the hydraulic contraction rod 132 is used to lower the second sealing cover 134, so that the second sealing cover 134 wraps around the top surface of the first sealing cover 121, and the output end of the material delivery pipe 14 penetrates into the internal of the one - way feeding port 122. If the output end of the material delivery pipe 14 and the one - way feeding port 122 are not aligned, the first motor 133 is used to rotate the second sealing cover 134, and the output end of the material delivery pipe 14 is aligned with the one - way feeding port 122. The angle of the second sealing cover 134 is adjusted by rotation to facilitate the effective insertion and docking between the second sealing cover 134 and the one - way feeding port 122.

[0045] When inserting the exhaust pipe 144 into the one-way feeding port 122, it is docked into the inner docking rib a6 inside the recessed groove two 141 on the bottom surface of the material conveying pipe 14, so that a relatively closed environment is formed between the one-way feeding port 122 and the material conveying pipe 14, and the material conveying pipe 14 can be effectively positioned and clamped inside the one-way feeding port 122. When the material conveying pipe 14 is clamped on the top surface of the one-way feeding port 122, the docking rib three 145 at the bottom end of the exhaust pipe 144 is docked and limited with the docking rib a6 on the top surface of the raised hard plate a4. Then, through the length of the exhaust pipe 144, the raised hard plate a4 is pressed down, so that the elastic flap a2 on the outer surface of the raised hard plate a4 is detached from the bottom surface of the one-way feeding port 122, forming a concave conical cavity between the elastic flap a2 and the one-way feeding port 122. At this time, the material conveying pipe 14 and the conical cavity are filled with coating through the feeding pipe two 142. The coating will accumulate inside the conical cavity, and after accumulation, the coating will be squeezed and discharged into the coating tank 12 along the discharge holes a3 on the outer surface of the elastic flap a2. Since the bottom of the raised hard plate a4 is in a sunken groove at this time, the coating liquid will not block the surface of the ventilation hole a5 before the coating in the coating tank 12 is completely filled;

[0046] When the coating in the coating tank 12 continuously accumulates, the excess air will be discharged into the exhaust pipe 144 along the ventilation hole a5. When the coating tank 12 is filled to a certain amount, the material conveying pipe 14 and the exhaust pipe 144 are pulled out from the one-way feeding port 122. At this time, the elastic flap a2 will reset due to its own elasticity, so that the discharge holes a3 on the outer surface of the elastic flap a2 are reattached to the bottom surface of the one-way feeding port 122. At this time, there is still coating liquid inside the elastic flap a2, and the coating liquid will form a sealing layer between the one-way feeding port 122 and the elastic flap a2. The coating liquid inside the conical cavity will also slowly fill to the top surface of the raised hard plate a4, making the inside of the coating tank 12 completely sealed, greatly isolating the outside air from entering the coating tank 12, and greatly reducing the effect of harmful substances in the interior decoration coating from spilling out.
