Description

Technical Field

[0001] The present application relates to the technical field of paint spraying, and in particular to a paint supply device with a liftable barrel cover. Background Art

[0002] Paint spraying on the surface of the product can protect and beautify it. With the application of automated spraying technology in production and manufacturing, the paint supply system is a key component of the spraying unit.

[0003] Because traditional paint supply systems primarily supply single-color paint and require a large installation footprint, adding another paint supply system increases space if additional colors need to be added during production. Therefore, a temporary solution is often found by installing a diaphragm pump and a stirring device on the paint bucket. The diaphragm pump is connected to the paint bucket via a siphon, and the pump and stirring device extends into the paint bucket. Alternatively, a separate bracket is constructed next to the paint bucket, on which the diaphragm pump is mounted, and the stirring device is attached to the paint bucket. During use, the stirring device mixes and stirs the paint for a uniform consistency. The diaphragm pump then pumps the paint out of the paint bucket and sprays it out through the spray gun. When the paint is used up, the worker lifts the bucket lid and places it on a new paint bucket. This integrated installation of the paint bucket, pump, and stirring device allows for short-distance paint supply, minimizing space and enabling quick transitions.

[0004] Regarding the above-mentioned related technologies, there are the following defects: the stirring device or pump installed on the barrel cover has a certain weight. When manually lifting the barrel cover when changing materials, there may be a risk of slipping out of the hand and causing injury, which needs further improvement. Utility Model Content

[0005] In order to improve the risk of manual lifting of the bucket cover, which may cause the bucket cover to slip out of the hand and cause injury, the present application provides a paint supply device with a liftable bucket cover.

[0006] The present application provides a paint supply device with a liftable barrel cover, which adopts the following technical solution:

[0007] A paint supply device with a liftable bucket cover includes a fixed bracket, a paint diaphragm pump arranged on the top of the fixed bracket, a bucket cover slidably connected to the fixed bracket, and a stirring device provided on the bucket cover. The bucket cover is also connected to a siphon tube for communicating with the paint bucket. The feed port of the paint diaphragm pump is connected to the siphon tube, and the siphon tube passes through the bottom of the bucket cover. The discharge port of the paint diaphragm pump is connected to a discharge hose. The fixed bracket is also provided with a drive assembly for driving the bucket cover to slide in the height direction of the fixed bracket.

[0008] By adopting the above technical solution, the paint diaphragm pump is installed on the fixed bracket, and a siphon tube is connected between the paint diaphragm pump and the bucket cover. Then the paint bucket can be directly placed on the bottom of the bucket cover. The paint in the paint bucket can be extracted using the paint diaphragm pump, and the stirring device is directly installed on the bucket cover to stir the paint. Under the action of the driving component, the bucket cover can be raised and lowered along the fixed bracket. After the paint is used up, the bucket cover can be quickly opened and replaced with a new paint bucket. The overall operation does not require the participation of workers, and is highly safe and easy to use.

[0009] Optionally, the driving assembly includes a lifting guide rail, a lifting cylinder, a connecting slider and a mounting bracket. The lifting guide rail is arranged on the fixed bracket, and the axis of the lifting guide rail is consistent with the height direction of the fixed bracket. The mounting bracket is fixedly connected to the barrel cover, one side of the connecting slider is fixedly connected to the mounting bracket, and the other side is slidably engaged on the lifting guide rail, and the output end of the lifting cylinder is fixedly connected to the mounting bracket.

[0010] By adopting the above technical solution, the connecting slider connects the mounting bracket to the lifting guide rail, and the bucket cover is fixedly connected to the mounting bracket. When the lifting cylinder pushes the mounting bracket, the connecting slider effectively slides along the lifting guide rail, thereby enabling the bucket cover to be effectively moved up and down, thereby being lifted from the paint bucket. The operation is convenient and the structure is reliable.

[0011] Optionally, a limit block is provided on the top of the lifting guide rail, and the limit block is made of non-metallic material.

[0012] By adopting the above technical solution, the limit block is set to limit the extreme position of the lifting guide rail, preventing the connecting slider from slipping off the lifting guide rail, and the non-metal limit block can prevent the connecting slider from colliding with the limit block, causing damage to the connecting slider, and is reliable to use.

[0013] Optionally, a manual lifting switch is also provided on the fixing bracket.

[0014] By adopting the above technical solution, a manual lifting switch is set to control the opening and closing of the lifting cylinder, which is easy to operate. Through manual control, the lifting cylinder can be closed at any time according to different situations during use, which is very practical.

[0015] Optionally, the paint diaphragm pump is connected to a paint pressure regulator, and the paint pressure regulator is located between the discharge port of the paint diaphragm pump and the discharge hose.

[0016] By adopting the above technical solution, the paint pressure regulator provided can control the spraying pressure of the paint, so that the paint coating accuracy is high and it is more suitable for coating different products.

[0017] Optionally, the outlet of the paint pressure regulator is set as a tee, the first end of the paint pressure regulator is connected to the discharge port of the paint diaphragm pump, the second end of the paint pressure regulator is connected to a return hose, the end of the return hose away from the paint pressure regulator passes through the bottom of the barrel cover, and the third end of the paint pressure regulator is connected to the discharge hose.

[0018] By adopting the above technical solution, the paint pressure regulator is set to a three-way valve, so that the pressure of the paint can be adjusted through the paint pressure regulator after the paint is extracted. After the paint spraying is completed, the connected return pipe can be used to replace the paint barrel with a solvent barrel, and then the solvent is extracted. The paint diaphragm pump paint pressure regulator is cleaned with the solvent. During the cleaning process, the solvent can be returned from the return pipe to the solvent barrel for recycling, which effectively saves solvent and has a good cleaning effect.

[0019] Optionally, a paint filter is connected between the discharge port of the paint diaphragm pump and the paint pressure regulator, and a waste valve is provided at the bottom of the paint filter.

[0020] By adopting the above technical solution, the paint filter can filter the paint, thereby improving the paint spraying effect, and the filtered particulate impurities can be discharged from the waste valve, which is easy to operate.

[0021] Optionally, a large mounting plate is provided at the bottom of the fixing bracket.

[0022] By adopting the above technical solution, installing the large plate effectively increases the connection area between the fixed bracket and the ground, thereby improving the stability of the fixed bracket, and the structure is simple and reliable.

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] The present application discloses a paint supply device with a liftable barrel cover. Figure 1 and Figure 2 , including a fixed bracket 1, a paint diaphragm pump 2 installed on the top of the fixed bracket 1, a bucket cover 3 slidably connected to the fixed bracket 1, and a stirring device 4 provided on the bucket cover 3. In this embodiment, the fixed bracket 1 is composed of two vertical rods 10 and a horizontal rod 11 welded together. The horizontal rod 11 is connected between the two vertical rods 10, and then a right-angle rod 12 is welded to the top of the two vertical rods 10. A connecting plate 13 is connected between the two right-angle rods 12. The connecting plate 13 is composed of a vertical plate 130 and a horizontal plate 131. A reinforcement rod 132 is also connected between the vertical plate 130 and the horizontal plate 131. At this time, the paint diaphragm pump 2 is connected to the connecting plate 530 by bolts, so that the paint diaphragm pump 2 is effectively connected to the fixed bracket 1;

[0031] A siphon tube 30 connected to the paint bucket is then connected to the bucket cover 3. The feed port of the paint diaphragm pump 2 is connected to the siphon tube 30 via a paint hose 20. The paint hose 20 is directly mounted on the paint diaphragm pump 2 and is made of a stainless steel mesh lined with Teflon tubing, making it easy to clean, non-damaging, and long-lasting. A connector 31 is then used to connect the paint hose 20 to the siphon tube 30, which then passes through the bottom of the bucket cover 3. During use, the paint hose 20 and connector 31 allow the paint diaphragm pump 2 to be directly connected to the barrel cover, without the need for additional structural modifications to the bucket cover 3 or the paint diaphragm pump 2. A discharge hose 21 is then connected to the discharge port of the paint diaphragm pump 2. The fixed bracket 1 is also provided with a drive assembly 5 for driving the bucket cover 3 to slide in the height direction of the fixed bracket 1.

[0032] During use, the paint bucket is placed at the bottom of the fixed bracket 1, and the paint bucket and the bucket cover 3 are located on the same axis. Then the driving component 5 drives the bucket cover 3 to be placed on the paint bucket. At this time, the siphon tube 30 is immersed in the paint bucket, and then the siphon tube 30 is connected to the paint hose 20. The stirring device 4 is started to mix and stir the paint to ensure the fluidity of the paint. Then the paint diaphragm pump 2 is started. After that, the paint diaphragm pump 2 effectively extracts the paint and discharges it from the discharge hose 21. The discharge hose 21 can be connected to the terminal spraying robot or manual spray gun, thereby effectively completing the paint spraying. In addition, in order to make the paint diaphragm pump 2 adaptable to different paints, an air pressure regulator 22 is also provided on the paint diaphragm pump 2. The air pressure regulator 22 is used to control the air pressure inside the paint diaphragm pump 2, so that the paint diaphragm pump 2 has a wide range of adaptability.

[0033] Reference Figure 1 In this embodiment, a paint pressure regulator 23 is also connected to the paint diaphragm pump 2, and the paint pressure regulator 23 is located between the discharge port of the paint diaphragm pump 2 and the discharge hose 21. During use, the paint spraying pressure is controlled by the paint pressure regulator 23 so that the paint spraying meets the product spraying effect. The outlet of the paint pressure regulator 23 is set as a three-way, and the first end of the paint pressure regulator 23 is connected to the discharge port of the paint diaphragm pump 2. The second end of the paint pressure regulator 23 is connected to the return hose 6. The end of the return hose 6 away from the paint pressure regulator 23 is passed to the bottom of the bucket cover 3. At this time, the return hose 6 is extended into the paint bucket, and finally the third end of the paint pressure regulator 23 is connected to the discharge hose 21.

[0034] During use, after the paint diaphragm pump 2 extracts the paint from the paint bucket, it regulates the pressure of the paint spray through the paint pressure regulator 23. The paint pressure regulator 23 adopts a diaphragm structure, which can effectively reduce the shearing of the paint. The paint after pressure regulation is further sprayed out from the discharge hose 21. However, the paint diaphragm pump 2 and each pipeline need to be cleaned regularly after a period of use. At this time, the cleaned solvent can be returned to the solvent bucket using a return pipe. The specific operating steps are: replace the raw material paint bucket with a solvent bucket and place it at the bottom of the bucket cover 3. Then use the paint diaphragm pump 2 to extract the solvent, and clean the paint diaphragm pump 2 and the paint pressure regulator 23, the discharge hose 21 and the paint hose 20 in turn. During the cleaning process, the solvent can be recycled through the reflux of the return pipe, which effectively saves solvent. When cleaning the discharge hose 21, the paint diaphragm pump 2 has been cleaned. The segmented cleaning of the paint diaphragm pump 2 and the discharge hose 21 saves cleaning time and solvent.

[0035] Reference Figure 1In this embodiment, in order to further improve the paint spraying accuracy, a paint filter 24 is connected between the discharge port of the paint diaphragm pump 2 and the paint pressure regulator 23 through a joint. The paint filter 24 adopts a filter structure and can be disassembled and cleaned regularly. The filtered paint can filter out particulate impurities in the paint, making the product spraying more uniform. In addition, a waste valve 25 is provided at the bottom of the paint filter 24. After the waste valve 25 is opened, the waste can be discharged directly from the bottom of the paint filter 24, which is convenient to use.

[0036] Reference Figure 1 In this embodiment, since the fixing bracket 1 carries many structures, in order to improve the stability of the fixing bracket 1, a mounting plate 14 is provided at the bottom of the fixing bracket 1. The cross-section of the mounting plate 14 is rectangular, and the mounting plate 14 is in direct contact with the ground. During installation, it can be directly fixed to the ground with bolts, which is convenient for assembly and disassembly. In addition, the mounting plate 14 is made of stainless steel. If paint falls on the mounting plate 14, it is easy to scrub, and the mounting plate 14 can directly prevent the paint from falling directly on the ground, thereby ensuring the cleanliness of the production workshop.

[0037] Reference Figure 1 In this embodiment, the stirring device 4 includes a stirring motor 40 and a stirring paddle 41. The stirring motor 40 is connected to the bucket cover 3. The stirring paddle 41 is fixedly connected to the stirring motor 40 and located at the bottom of the bucket cover 3. When the bucket cover 3 is placed on the paint bucket, the stirring paddle 41 extends into the mixing bucket to effectively stir the paint. The stirring motor 40 is pneumatically operated, and a precision throttle valve (not shown) is provided at the air inlet to effectively adjust the stirring speed.

[0038] Reference Figure 1 and Figure 2 In this embodiment, the driving assembly 5 includes a lifting guide rail 50, a lifting cylinder 51, a connecting slider 52, and a mounting bracket 53. The lifting guide rail 50 is arranged on the fixed bracket 1 and is located on the two vertical rods 10, and the axis of the lifting guide rail 50 is consistent with the height direction of the fixed bracket 1; then the mounting bracket 53 is fixedly connected to the barrel cover 3. The mounting bracket 53 consists of two connecting plates 530, two fixed rods 531, and a crossbeam 532. The two connecting plates 530 are respectively connected to the two sides of the barrel cover 3, and the two fixed rods 531 are respectively fixedly connected to the two connecting plates 530. The crossbeam 532 is connected between the two fixed rods 531. Then, one side of the connecting slider 52 is fixedly connected to the fixed rod 531 through the connecting shaft 533, and the other side is slidably connected to the lifting guide rail 50. The lifting cylinder 51 is arranged on the mounting plate 14, and the output end of the lifting cylinder 51 is fixedly connected to the crossbeam 532.

[0039] During use, the lifting cylinder 51 is activated to push the crossbeam 532, and then the connecting plate 530 is driven together to produce an upward displacement trend. At this time, the connecting slider 52 slides along the lifting guide rail 50, effectively realizing the drive of the barrel cover 3. The lifting guide rails 50 set on both sides improve the operational stability, and the lifting cylinder 51 is vertically extended and retracted upward, and the structure is stable. In addition, a lifting manual switch 7 is also provided on the connecting plate 13 on the fixed bracket 1. The lifting manual switch 7 can be used to control the opening and closing of the lifting cylinder 51. Manual control is convenient and emergency braking can be performed according to different usage conditions.

[0040] Reference Figure 1 and Figure 2 In this embodiment, in order to prevent the connection from falling off the lifting guide rail 50 during sliding operation, a limit block 8 is provided at the top of the lifting guide rail 50. The limit block 8 is used to limit the extreme position of the lifting guide rail. The limit block 8 is made of non-metallic material and can effectively buffer the collision between the connection slider 52 and the limit block 8, thereby protecting the connection slider 52 from damage.

[0041] The implementation principle of the paint supply device with a liftable bucket cover in the embodiment of the present application is as follows: a paint bucket is placed on the mounting plate 14, and then the bucket cover 3 is placed on the paint bucket using the lifting cylinder 51, and then the stirring device 4 is started to stir and mix the paint; the paint diaphragm pump 2 is then started to extract the paint, and the paint is connected to the spraying robot or the manual spray gun through the discharge hose 21, so that the paint is effectively applied to the product, and in the process of extracting the paint, the paint pressure regulator 23 and the paint filter 24 respectively regulate the pressure and filter the paint to improve the spraying effect; finally, by replacing the paint bucket with a solvent bucket and using a return pipe to reflux the solvent, the paint diaphragm pump 2, the discharge hose 21 and other structures can be effectively cleaned after the spraying is completed. The overall operation does not require workers to manually lift the bucket cover 3, which is very convenient, and the overall structure installation occupies a small area and can be quickly converted for use.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
