[0001] The present application relates to the technical field of paint transfer equipment, and in particular to a pneumatic paint replenishing device. Background Art
[0002] When painting, the used paint is added to the corresponding paint tank, and after the paint is used up, new paint needs to be added to the paint tank.
[0003] At present, common paint buckets are all over 200KG, which makes it inconvenient to move the paint bucket to the vicinity of the paint tank to load the paint tank.
[0004] In order to facilitate adding paint to the corresponding paint tank, it is often necessary to add a special paint extraction device, and then use the paint extraction device to divide the paint in the paint bucket into several small buckets, and finally add the paint to the corresponding paint tank through the small buckets.
[0005] Regarding the above-mentioned related technologies, when painting, sometimes multiple paints need to be mixed. If the method of packaging in small buckets is adopted, more small buckets need to be prepared, and they need to be cleaned after use, which requires high labor costs. Utility Model Content
[0006] The present application provides a pneumatic paint replenishing device, the purpose of which is to directly press out the paint in the paint bucket by air pressure, avoiding the use of small buckets for packaging, and reducing labor costs.

[0011] By adopting the above technical solution, first, an air inlet is opened on the paint bucket and is connected to a discharge pipe, so high-pressure gas is filled through the air inlet, and then the high-pressure gas can press the paint in the paint bucket out of the paint bucket through the discharge pipe, and then the paint in the paint bucket can be directly loaded into the corresponding paint tank.
[0012] Secondly, the paint bucket is placed on the transfer cart so that the heavier paint bucket can move freely, thereby ensuring that the paint bucket can be moved to the corresponding position, thereby achieving the replenishment of paint.
[0013] In addition, the setting of several reinforcing columns on the transfer cart can, on the one hand, fix the paint bucket to prevent it from tipping over during the transfer process; on the other hand, due to the high-pressure gas pressed inside the paint bucket, the paint bucket is easy to deform, so the deformation of the paint bucket can be reduced by using several reinforcing columns.

[0020] However, no connecting bent rod is arranged between the first column and the second column, so a loading and unloading port is formed between the first column and the second column, through which the paint bucket can be easily loaded and unloaded.

[0022] A vertical adjusting member for driving the vertical pressing plate to move axially along the first column is arranged between the vertical pressing plate and the first column.
[0023] By adopting the above technical solution, since the paint bucket is located between the vertical pressing plate and the transfer cart, and the vertical pressing plate abuts against the paint bucket, the vertical pressing plate can fix the paint bucket on the transfer cart.
[0024] The setting of the vertical adjusting member can adjust the position of the vertical pressing plate to facilitate the replacement of the paint bucket.

[0027] The fixing nut is sleeved on the outside of the vertical screw rod, and the fixing nut is located on the side of the vertical pressure plate away from the transfer trolley, and the fixing nut is connected to the vertical screw rod through threads.
[0028] By adopting the above technical solution, the cooperation between the vertical screw rod and the through hole enables the vertical pressure plate to slide on the vertical screw rod along the axial direction of the vertical screw rod, and a fixing nut is sleeved on the outer side of the vertical screw rod, so the position of the fixing nut is adjusted so that the vertical pressure plate is located between the paint bucket and the fixing nut, thereby fixing the vertical pressure plate and adjusting the vertical pressure plate to abut the paint bucket.
[0029] Optionally, a disassembly handle is provided on a side of the vertical pressing plate away from the paint bucket.
[0030] By adopting the above technical solution and disassembling the handle, the installation and disassembly of the vertical pressing plate is facilitated.

When high-pressure gas is injected into the paint bucket 2 through the air inlet 21, the paint in the paint bucket 2 will be automatically discharged from the discharge pipe 22, so that the paint can be automatically replenished. In order to reduce the amount of residual paint in the paint bucket 2, the part of the discharge pipe 22 located in the paint bucket 2 should be extended to the bottom of the paint bucket 2 as much as possible.
[0054] Reference Figure 1 An anti-deformation component 3 is provided on the transfer cart 1, and the anti-deformation component 3 includes a plurality of reinforcing columns 31. The axial direction of the reinforcing column 31 is arranged along the vertical direction, and the lower end of the reinforcing column 31 is fixedly connected to the transfer cart 1. The plurality of reinforcing columns 31 are arranged around the paint bucket 2 along the circumference of the paint bucket 2, and a plurality of connecting bent rods 32 are arranged between two adjacent reinforcing columns 31 along the circumference of the paint bucket 2. The plurality of connecting bent rods 32 are arranged in sequence at intervals along the axial direction of the reinforcing columns 31, and the two ends of the connecting bent rods 32 are respectively fixedly connected to the corresponding reinforcing columns 31.
[0055] By cooperating with a plurality of reinforcing columns 31 and a plurality of connecting bent rods 32, a protective layer can be formed on the outside of the paint bucket 2, so that when the paint bucket 2 is deformed due to the introduction of high-pressure gas into the paint bucket 2, the deformation of the paint bucket 2 can be limited to prevent the paint bucket 2 from being damaged.
[0056] Reference Figure 1 and Figure 2 Moreover, there is no connecting bent rod 32 between two adjacent reinforcing columns 31, so that a loading and unloading port 33 is formed between the two reinforcing columns 31.

The fixing nut 352 is located on the upper side of the vertical pressure plate 34 in the vertical direction. Therefore, by removing the fixing nut 352, the position of the vertical pressure plate 34 can be adjusted in the vertical direction, so the vertical pressure plate 34 can be locked to the paint bucket 2.
[0062] In addition, the vertical adjustment member 35 can also adopt a cylinder, a hydraulic cylinder or a linear push rod, and the upper end of the vertical adjustment member 35 is detachably connected to the vertical pressure plate 34 to ensure that the vertical pressure plate 34 can be disassembled.
