Description

Technical Field

[0001] The present application relates to the field of water-based paint processing technology, and in particular to a water-based paint quantitative filling system. Background Art

[0002] Water-based paint is an environmentally friendly paint widely used in building decoration. It is harmless to the human body and does not pollute the environment. It has good flexibility and is water-resistant, wear-resistant, and aging-resistant. Water-based paint uses water as a solvent, which saves a lot of resources, eliminates the risk of fire during construction, and reduces air pollution. It only uses a small amount of low-toxic alcohol ether organic solvents, which improves the working environment conditions and has a significant effect on reducing pollution and saving resources. Generally, most of them are stored in barrels during production for easy packaging, storage, and transportation.

[0003] In the prior art, a common water-based paint filling system is mainly composed of a conveying mechanism, a raw material tank and a filling mechanism, etc. The conveying mechanism conveys the paint bucket to the bottom of the filling mechanism, and the filling mechanism is connected to the raw material tank. The filling mechanism is mainly composed of a paint filling pipe, a flow meter, a valve, etc. The conveying mechanism conveys the paint bucket to the bottom of the paint filling pipe in sequence according to a set frequency. When the valve is opened, the water-based paint flows into the paint bucket through the paint filling pipe. During this process, the flow meter detects the amount of water-based paint flowing out through the paint filling pipe. When the amount of water-based paint reaches the set amount, the valve is closed, and the conveying mechanism conveys the next empty paint bucket to the bottom of the paint filling pipe.

[0004] However, when the valve is closed, the residual water-based paint in the paint injection tube is likely to drip onto the conveying mechanism, causing inconvenience in subsequent cleaning work, and there is room for improvement. Utility Model Content

[0005] In order to reduce the residual water-based paint dripping and polluting the equipment, causing inconvenience in cleaning work, the present application provides a water-based paint quantitative filling system.

[0006] The water-based paint quantitative filling system provided in this application adopts the following technical solution:

[0007] A quantitative filling system for water-based paint comprises a frame, a filling mechanism is fixedly mounted on the frame, a paint injection pipe of the filling mechanism is mounted above a conveying mechanism, a liquid collecting tank is slidably connected to the frame, a liquid infusion pipe is connected to the bottom of the liquid collecting tank, a liquid collecting box is fixedly mounted on the frame, and a liquid outlet end of the liquid infusion pipe is connected to the liquid collecting box; and:

[0008] A flow meter is installed on the paint injection pipe to detect the amount of water-based paint flowing out of the paint injection pipe and output a paint injection amount signal;

[0009] A signal processing unit, connected to the signal output terminal of the flow meter, for receiving and comparing the paint injection amount signal, and outputting a first control signal when the paint injection amount reaches a set value or an integer multiple of the set value;

[0010] A driving unit, fixedly mounted on the frame, with a driving end fixedly connected to the outer wall of the liquid collecting tank and connected to the signal output end of the signal processing unit, for receiving the first control signal and driving the liquid collecting tank to slide to the bottom of the paint injection pipe;

[0011] An empty barrel sensing unit is fixedly mounted at the bottom of the liquid collecting tank and is signal-connected to the signal output end of the signal processing unit, and is used to receive the first control signal and sense the empty barrel delivered to the bottom of the paint injection pipe, and output a second control signal;

[0012] The signal input end of the driving unit is signal-connected to the signal output end of the empty barrel sensing unit. The driving unit receives the second control signal and drives the liquid collecting tank to move in a direction away from the paint injection pipe.

[0013] By adopting the above technical solution, during the actual production and processing, the conveying mechanism conveys the paint bucket to the bottom of the paint injection tube at a set frequency. When the paint injection tube is filled with paint and the valve is closed, the signal processing unit controls the driving unit to drive the liquid collecting tank to slide to the bottom of the paint injection tube, receiving the residual and dripping water-based paint from the paint injection tube, and conveying the water-based paint in the liquid collecting tank to the liquid collecting box through the liquid infusion tube, so as to prevent the water-based paint from dripping on the conveying mechanism and contaminating the conveying mechanism, causing inconvenience in subsequent cleaning work. In addition, since an empty barrel sensing unit is installed at the bottom of the liquid collecting tank, when the empty barrel sensing unit senses that the empty barrel is conveyed to the bottom of the paint injection tube, the empty barrel sensing unit can control the driving unit to drive the liquid collecting tank to move in the direction away from the paint injection tube, so that the paint injection tube is directly above the empty barrel, which is convenient for the paint injection tube to pour water-based paint into the empty barrel, and the technical effect of automatically sensing the empty barrel and automatically removing the liquid collecting tank can be achieved.

[0014] Preferably, two guide rods are fixedly connected to the frame, and the two guide rods are located on both sides of the paint injection pipe;

[0015] The bottom of the liquid collecting tank is fixedly connected with two sleeves, and the two sleeves are coaxially sleeved on the two guide rods respectively.

[0016] By adopting the above technical solution, the sleeve fixed at the bottom of the liquid collecting tank is arranged on the guide rod. When the driving unit drives the liquid collecting tank to slide, it can ensure that the liquid collecting tank slides in a straight line along the axial direction of the guide rod, thereby improving the stability of the sliding action of the liquid collecting tank and reducing the occurrence of position deviation of the liquid collecting tank during the sliding process.

[0017] Preferably, limiting grooves are respectively provided on both sides of the guide rod along the axial direction, and limiting sliders are respectively integrally formed on the two opposite inner side walls of the sleeve, and the two limiting sliders are respectively embedded and slidably arranged in the two limiting grooves.

[0018] By adopting the above technical solution, the limiting slider is embedded and slidably arranged in the limiting groove, which can further improve the sliding stability of the liquid collecting trough and reduce the occurrence of the liquid collecting trough deviation.

[0019] Preferably, the signal processing unit includes a single chip microcomputer, the signal input end of the single chip microcomputer is signal-connected to the signal output end of the flow meter, and the signal output end of the single chip microcomputer is signal-connected to the signal input ends of the drive unit and the empty barrel sensing unit.

[0020] By adopting the above technical solution, the single chip microcomputer can determine whether the valve is closed according to the actual amount of paint injected, and automatically control the drive unit to slide to the bottom of the paint injection pipe when the valve is closed and the paint bucket after injection is sent out.

[0021] Preferably, the driving unit comprises a cylinder, a cylinder body of the cylinder is fixedly connected to the frame, and a cylinder shaft of the cylinder is fixedly connected to an outer side wall of the liquid collecting tank.

[0022] By adopting the above technical solution, the cylinder can extend or retract the cylinder axis to drive the liquid collecting tank to move towards or away from the paint injection pipe.

[0023] Preferably, the empty barrel sensing unit comprises:

[0024] An ultrasonic distance measuring sensor is fixedly mounted on the outer bottom of the liquid collecting tank, with its sensing end facing the conveying mechanism, and is connected to the signal output end of the single chip microcomputer, for receiving the first control signal and outputting a sensing distance signal;

[0025] The comparator chip is connected to the signal output terminal of the ultrasonic distance measuring sensor, and is used to receive and compare the sensing distance signal, and output the second control signal when the sensing distance is within a set range.

[0026] By adopting the above technical solution, since the bottom of the paint bucket has a certain thickness, when the empty paint bucket is transported to the bottom of the liquid collecting tank, the sensing distance measured by the ultrasonic ranging sensor is within the set range. After comparison, the comparator chip can determine that the empty paint bucket is transported to the bottom of the paint injection pipe and the liquid collecting tank, and judge that the next round of paint injection operation will be carried out, and control the telescopic cylinder to retract the cylinder shaft to drive the liquid collecting tank to move in the direction away from the paint injection pipe, thereby achieving the technical effect of automatically sensing the empty bucket and automatically recycling the liquid collecting tank.

[0027] Preferably, the infusion tube is a telescopic tube.

[0028] By adopting the above technical solution, the telescopic tube can ensure the normal sliding of the liquid collecting tank while shortening the space occupied by the tube body on the rack.

[0029] In summary, the quantitative filling system of water-based paint in the present application includes at least one of the following beneficial technical effects:

[0030] 1. Through the coordination and use of the flow meter, single-chip microcomputer, cylinder and liquid collecting tank, the cylinder can be automatically controlled to drive the liquid collecting tank to slide to the bottom of the paint injection pipe after the paint injection is completed, and the residual and dripping water-based paint in the paint injection pipe is received, and the water-based paint is transported to the liquid collecting box through the infusion pipe connected to the liquid collecting tank, which can reduce the residual and dripping water-based paint in the paint injection pipe from dripping onto the equipment, and reduce the difficulty and intensity of subsequent cleaning work;

[0031] 2. By matching and using the guide rod, sleeve and limit slider, the sliding track of the liquid collecting tank can be restricted, the position deviation of the liquid collecting tank during the sliding process can be reduced, and the stability of the liquid collecting tank can be improved;

[0032] 3. Through the mutual coordination and use of the single-chip microcomputer, ultrasonic distance measuring sensor, comparator chip and liquid collecting tank, the empty paint bucket under the liquid collecting tank can be sensed and transmitted, and the cylinder can be automatically controlled to return to the liquid collecting tank, so as to facilitate the paint injection operation of the paint injection pipe.

[0037] The following is combined with Figure 1-2 This application is described in further detail.

[0038] Example

[0039] The present application embodiment discloses a water-based paint quantitative filling system. Figure 1 and Figure 3, including a frame 1, a filling mechanism 2 fixedly installed on the frame 1, a paint injection pipe 21 of the filling mechanism 2 is mounted above the conveying mechanism, a liquid collecting tank 3 is slidably connected to the frame 1, a liquid infusion pipe 31 is installed at the bottom of the liquid collecting tank 3, a liquid collecting box 32 is fixedly installed on the frame 1, and the liquid outlet end of the liquid infusion pipe 31 is connected to the liquid collecting box 32.

[0040] And: a flow meter 22, installed on the paint injection pipe 21, for detecting the amount of water-based paint flowing out through the paint injection pipe 21 and outputting a paint injection amount signal; a signal processing unit, signal-connected to the signal output end of the flow meter 22, for receiving and comparing the paint injection amount signal, and outputting a first control signal when the paint injection amount reaches a set value or an integer multiple of the set value; a driving unit, fixedly installed on the frame 1, with the driving end fixedly connected to the outer wall of the liquid collecting tank 3, and signal-connected to the signal output end of the signal processing unit, for receiving the first control signal and driving the liquid collecting tank 3 to slide to the bottom of the paint injection pipe 21; an empty barrel sensing unit, fixedly installed at the bottom of the liquid collecting tank 3, and signal-connected to the signal output end of the signal processing unit, for receiving the first control signal and sensing the empty barrel transported to the bottom of the paint injection pipe 21, and outputting a second control signal.

[0041] The signal input end of the driving unit is signal-connected to the signal output end of the empty barrel sensing unit. The driving unit receives the second control signal and drives the liquid collecting tank 3 to move in a direction away from the paint injection tube 21 .

[0042] During the actual production and processing process, the conveying mechanism conveys the paint bucket 6 to the bottom of the paint injection tube 21 at a set frequency. When the paint injection tube 21 is filled with paint and the valve is closed, the signal processing unit controls the driving unit to drive the collecting tank 3 to slide to the bottom of the paint injection tube 21, to receive the residual and dripping water-based paint from the paint injection tube 21, and to convey the water-based paint in the collecting tank 3 to the collecting tank 32 through the infusion tube 31, so as to prevent the water-based paint from dripping onto the conveying mechanism and contaminating the conveying mechanism, causing inconvenience in subsequent cleaning work.

[0043] In addition, since an empty barrel sensing unit is installed at the bottom of the liquid collecting tank 3, when the empty barrel sensing unit senses that the empty barrel is transported to the bottom of the paint injection tube 21, the empty barrel sensing unit can control the driving unit to drive the liquid collecting tank 3 to move in a direction away from the paint injection tube 21, so that the paint injection tube 21 is directly above the empty barrel, which is convenient for the paint injection tube 21 to pour water-based paint into the empty barrel, thereby achieving the technical effect of automatically sensing the empty barrel and automatically removing the liquid collecting tank 3.

[0044] Reference Figure 1 and Figure 2 Two guide rods 11 are fixedly connected to the frame 1, and the two guide rods 11 are located on both sides of the paint injection pipe 21; two sleeves 33 are fixedly connected to the bottom of the liquid collecting tank 3, and the two sleeves 33 are coaxially sleeved on the two guide rods 11 respectively.

[0045] The sleeve 33 fixed at the bottom of the liquid collecting tank 3 is sleeved on the guide rod 11. When the driving unit drives the liquid collecting tank 3 to slide, it can ensure that the liquid collecting tank 3 slides in a straight line along the axial direction of the guide rod 11, thereby improving the stability of the sliding action of the liquid collecting tank 3 and reducing the occurrence of position deviation of the liquid collecting tank 3 during the sliding process.

[0046] Reference Figure 2 The two sides of the guide rod 11 are respectively provided with limit grooves 111 along the axial direction, and the two opposite inner side walls of the sleeve 33 are respectively integrally formed with limit sliders 331, and the two limit sliders 331 are respectively embedded and slidably set in the two limit grooves 111.

[0047] The limiting slider 331 is embedded and slidably disposed in the limiting groove 111 , which can further improve the sliding stability of the liquid collecting groove 3 and reduce the occurrence of the deviation of the liquid collecting groove 3 .

[0048] In the embodiment of the present application, the signal processing unit adopts a single-chip microcomputer, the signal input end of the single-chip microcomputer is connected to the signal output end of the flow meter 22, and the signal output end of the single-chip microcomputer is connected to the signal input end of the driving unit and the empty barrel sensing unit.

[0049] The single chip microcomputer can determine whether the valve is closed according to the actual amount of paint injected, and automatically control the driving unit to slide to the bottom of the paint injection pipe 21 when the valve is closed and the paint bucket 6 after injection is sent out.

[0050] Reference Figure 1 and Figure 3 In the embodiment of the present application, the driving unit is a cylinder 4, the cylinder body of the cylinder 4 is fixedly connected to the frame 1, and the cylinder 4 axis of the cylinder 4 is fixedly connected to the outer wall of the liquid collecting tank 3. The cylinder 4 extends or retracts the cylinder 4 axis, which can drive the liquid collecting tank 3 to move toward or away from the paint injection pipe 21.

[0051] Reference Figure 2 and Figure 3 The empty barrel sensing unit includes: an ultrasonic distance sensor 5, which is fixedly installed on the outer bottom of the liquid collecting tank 3, with the sensing end facing the conveying mechanism, and is connected to the signal output end of the single-chip computer for receiving a first control signal and outputting a sensing distance signal; a comparator chip, which is connected to the signal output end of the ultrasonic distance sensor 5 for receiving and comparing the sensing distance signal, and outputting a second control signal when the sensing distance is within a set range.

[0052] Since the bottom of the paint bucket 6 has a certain thickness, when the empty paint bucket 6 is transported to the bottom of the liquid collecting tank 3, the sensing distance measured by the ultrasonic ranging sensor 5 is within the set range. After comparison, the comparator chip can determine that the empty paint bucket 6 is transported to the bottom of the paint injection tube 21 and the liquid collecting tank 3, and judge that the next round of paint injection operation will be carried out, and control the telescopic cylinder 4 to retract the cylinder 4 axis to drive the liquid collecting tank 3 to move in the direction away from the paint injection tube 21, thereby achieving the technical effect of automatically sensing the empty bucket and automatically recycling the liquid collecting tank 3.

[0053] It should be noted that, in the embodiment of the present application, the infusion tube 31 is a telescopic tube, which can ensure the normal sliding of the liquid collecting tank 3 and shorten the space occupied by the tube body on the frame 1.

[0054] The implementation principle of the quantitative filling system of water-based paint in the embodiment of the present application is as follows: through the mutual coordination and use of the flow meter 22, the single-chip computer, the cylinder 4, and the liquid collecting tank 3, the cylinder 4 can be automatically controlled to drive the liquid collecting tank 3 to slide to the bottom of the paint injection tube 21 after the paint injection is completed, and the residual and dripping water-based paint in the paint injection tube 21 is received, and the water-based paint is transported to the liquid collecting box 32 through the infusion tube 31 connected to the liquid collecting tank 3, which can reduce the occurrence of the residual and dripping water-based paint in the paint injection tube 21 dripping onto the equipment, and reduce the subsequent cleaning work. The difficulty and strength of the operation are reduced; through the mutual coordination and use of the guide rod 11, the sleeve 33, and the limit slider 331, the sliding trajectory of the liquid collecting tank 3 can be restricted, the position deviation of the liquid collecting tank 3 during the sliding process can be reduced, and the stability of the liquid collecting tank 3 can be improved; through the mutual coordination and use of the single-chip microcomputer, the ultrasonic ranging sensor 5, the comparator chip and the liquid collecting tank 3, the empty paint bucket 6 under the liquid collecting tank 3 can be sensed and transmitted, and the cylinder 4 can be automatically controlled to return to the liquid collecting tank 3, so that the paint injection pipe 21 can perform the paint injection operation.
