Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paint spraying equipment, in particular to a high-efficiency paint spraying method and equipment. BACKGROUND

[0002] Generally, workpieces need to be painted during processing. The paint spraying function is first protective to prolong the service life of the workpiece, secondly decorative to achieve beauty, and thirdly special to achieve special performance such as sound insulation, heat insulation, and fireproofing.

[0003] Currently, there are two main paint spraying methods. One is manual paint spraying, which is harmful to the health of workers and labor-intensive. Therefore, paint spraying is generally replaced by mechanical equipment.

[0004] During the paint spraying process of the mechanical equipment, the spraying amount and spraying range of the spray head are generally limited. The uniform paint spraying of the workpiece surface is achieved by moving the workpiece and the spray head. If the same machine is used to spray large and small workpieces, the paint spraying of different workpieces can only be achieved by adjusting the paint spraying path. Thus, the paint spraying efficiency of large workpieces cannot be guaranteed. SUMMARY

[0005] The present application discloses a high-efficiency paint spraying method and equipment, which aims to solve the technical problem that if the same machine is used to spray large and small workpieces, the paint spraying of different workpieces can only be achieved by adjusting the paint spraying path, and thus the paint spraying efficiency of large workpieces cannot be guaranteed.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0007] A high-efficiency paint spraying equipment includes a paint spraying warehouse, a conveying belt, and a paint spraying mechanism. The paint spraying mechanism is located on one side of the conveying belt. One side of the paint spraying warehouse is provided with a drying mechanism and a heat conduction adjusting mechanism.

[0008] The paint spraying mechanism includes a sliding rail, a bottom frame movably connected to the sliding rail through a sliding block, a base fixedly connected to the top end of the bottom frame, and three spray guns provided on the top end of the base. The bottom end of the middle spray gun is fixed to the outer wall of the top end of the base through a fixing frame. The other two spray guns are symmetrically arranged on both sides of the middle spray gun.

[0009] The bottom end of each of the other two spray guns is fixedly connected to a support rod, and the support rod is movably arranged on the base. The outer walls of the two support rods are respectively fixedly connected to half gears, and the two half gears are meshed with each other. The bottom end of one of the support rods is fixedly connected to a motor, and the motor is connected to the bottom end of the base.

[0010] The input ends of the three spray guns are tightly connected to liquid-filling hoses, and each liquid-filling hose is equipped with a flow regulating valve. Multiple liquid-filling hoses are simultaneously connected to a four-way pipe, and the input end of the four-way pipe is tightly connected to a main liquid-filling pipe. One end of the main liquid-filling pipe is connected to a paint storage tank.

[0011] By incorporating a painting mechanism that drives two spray guns to move synchronously outwards or inwards to change the spray range, and by using multiple flow control valves to differentiate and adjust the paint flow of each spray gun to change its spray range, this structure, while ensuring that the spray gun in the middle can spray normally, can meet the single spray range of workpieces of different volumes by selecting the use of the other two spray guns, adjusting their spray angles, and adjusting the spray range. Furthermore, by changing the spray angles to make the spray points of the three spray guns be in the same position, the spray thickness can be increased, thereby effectively improving the painting efficiency.

[0012] In a preferred embodiment, the drying mechanism includes a mounting plate on which multiple guide fans are mounted simultaneously. An activated carbon filling plate is located on the opposite side of the guide fans inside the paint spray chamber. A thermometer is located at the bottom of the mounting plate. A support plate is tightly fastened to the inner wall of the paint spray chamber on the opposite side of the activated carbon filling plate. Multiple suction pipes are fixedly connected to the support plate, with the suction ends of the suction pipes facing downwards. The output ends of the multiple suction pipes are simultaneously connected to filters. The output ends of the filters are connected to a high-temperature incinerator. One outer wall of the high-temperature incinerator is heat-conducting, and its heat-conducting side is connected to a heat conduction adjustment mechanism. The other side of the heat conduction adjustment mechanism is connected to a radiator, the radiator being positioned corresponding to the air inlet of the multiple guide fans.

[0013] Equipped with a drying mechanism, the exhaust gas generated during painting is sequentially drawn into a filter and a high-temperature incinerator through the suction pipe for treatment. The gas is then heated on the heat-conducting side of the incinerator, and the temperature is regulated by a heat-conducting adjustment mechanism. The high temperature is then dissipated into the paint spraying chamber through a radiator, and the hot air is directed to the exterior of the workpiece by a guide fan. Simultaneously, the activated carbon filling plate reduces the humidity inside the paint spraying chamber and absorbs odors from the exhaust gas. This allows for efficient drying of the paint spraying process while simultaneously utilizing the heat energy generated during exhaust gas treatment, thus improving work efficiency.

[0014] In a preferred embodiment, the heat conduction adjustment mechanism includes a heat insulation cover, inside which multiple heat conduction plates are fixedly connected at equal density. Each heat conduction plate has a heat insulation plate fixedly connected to its top. A radiator is fixed to the outer wall of the outermost heat conduction plate. Heat conduction blocks are tightly and movably connected to the inner walls of adjacent heat conduction plates. Each heat conduction block has a telescopic rod connected to its top. Multiple telescopic rods are simultaneously fixed to the inner wall of the top of the heat insulation cover. Argon gas delivery pipes are tightly connected to the inner wall of one side of the heat insulation cover. Each argon gas delivery pipe corresponds to the gap between two adjacent heat conduction plates. Multiple argon gas delivery pipes are simultaneously connected to an argon gas conveyor.

[0015] A high-efficiency painting method, applied to the high-efficiency painting equipment described in the claims, includes the following specific steps:

[0016] S1: Equipment Adjustment: Adjust the values ​​of the painting mechanism and heat conduction adjustment mechanism according to processing requirements;

[0017] S2: Start Equipment: Start the overall painting equipment;

[0018] S3: Spray painting: The spray painting mechanism sprays paint on the exterior of the workpieces conveyed on the conveyor belt;

[0019] S4: Drying: Using a drying mechanism to dry the workpieces on the conveyor belt;

[0020] S5: Exhaust gas treatment: While the drying process is underway, the exhaust gas generated during the painting process is treated through a high-temperature incinerator and a filter.

[0021] The S1 debugging device includes the following specific steps:

[0022] S11: Input workpiece values: Scan the workpiece or directly input the workpiece specifications to obtain the workpiece's specification values;

[0023] S12: Adjusting the spray painting mechanism: Automatically adjusts the opening and closing angles of two spray guns in the spray painting mechanism according to the obtained workpiece specification values, and adjusts the spraying range of the spray guns by adjusting the flow regulating valve.

[0024] S13: Temperature measurement: Open the high-temperature incinerator and obtain the internal temperature of the paint spraying chamber using a thermometer;

[0025] S14: Adjust the heat conduction adjustment mechanism: Adjust the heat conduction efficiency of the heat conduction adjustment mechanism according to the obtained temperature value.

[0026] By incorporating a heat conduction adjustment mechanism, the heat conduction block can be lifted to the position of the heat insulation plate by controlling different numbers of telescopic rods. This eliminates the heat conduction path between two adjacent heat conduction plates, and the heat is then transported to the gap through an argon gas conveyor and argon gas delivery pipe. The argon gas filling the gap provides a certain degree of heat insulation, reduces heat conduction efficiency, and thus lowers the temperature of the heat dissipated by the radiator. This ensures efficient drying while preventing the paint surface from cracking due to excessively high temperatures inside the paint booth, thus guaranteeing the painting effect.

[0027] As can be seen from the above, an efficient painting method and equipment includes a paint spraying chamber, in which a conveyor belt and a painting mechanism are simultaneously arranged. The painting mechanism is located on one side of the conveyor belt, and a drying mechanism and a heat conduction adjustment mechanism are simultaneously arranged on one side of the paint spraying chamber. The painting mechanism includes a slide rail, on which a base frame is movably connected via a slider. A base is fixedly connected to the top of the base frame, and three spray guns are simultaneously arranged on the top of the base frame. The bottom end of the spray gun located in the middle is fixed to the outer wall of the top of the base frame via a fixing bracket, and the other two spray guns are symmetrically arranged on both sides of the spray gun. Two other spray guns are fixedly connected to their bottom ends with support rods, which are movably mounted on the base. Half-gears are fixedly connected to the outer walls of each support rod, and these half-gears mesh with each other. A motor is fixedly connected to the bottom end of one of the support rods, and the motor is also connected to the bottom end of the base. The input ends of the three spray guns are tightly connected to flexible fluid hoses, each hose equipped with a flow regulating valve. Multiple flexible fluid hoses are simultaneously connected to a four-way connector, the input end of which is tightly connected to a main fluid pipe. One end of the main fluid pipe is connected to a paint storage tank. The efficient painting method and equipment provided by this invention can meet the single-spray range requirements of workpieces of different volumes and increase the spray thickness, thereby effectively improving painting efficiency.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] The efficient painting method and equipment disclosed in this invention are mainly applied to workpiece painting scenarios.

[0036] Reference Figure 1 , Figure 2 and Figure 4 A high-efficiency painting equipment includes a paint spraying chamber 3, a conveyor belt 5 and a painting mechanism 4 are installed in the paint spraying chamber 3, the painting mechanism 4 is located on one side of the conveyor belt 5, and a drying mechanism 1 and a heat conduction adjustment mechanism 2 are installed on one side of the paint spraying chamber 3.

[0037] The painting mechanism 4 includes a slide rail 401, a base frame 404 is movably connected to the slide rail 401 via a slider 405, a base 412 is fixedly connected to the top of the base frame 404, and three spray guns 406 are simultaneously arranged on the top of the base 412. The bottom end of the spray gun 406 located in the middle is fixed to the outer wall of the top of the base 412 via a fixing bracket 411, and the other two spray guns 406 are symmetrically arranged on both sides of the spray gun 406.

[0038] The bottom ends of the other two spray guns 406 are fixedly connected to support rods 407, and the support rods 407 are movably mounted on the base 412. The outer walls of the two support rods 407 are respectively fixedly connected to half gears 413, and the two half gears 413 mesh with each other. The bottom end of one of the support rods 407 is fixedly connected to a motor 414, and the motor 414 is also connected to the bottom end of the base 412.

[0039] The input ends of the three spray guns 406 are respectively tightly connected to liquid-filling hoses 409, and each liquid-filling hose 409 is equipped with a flow regulating valve 408. Multiple liquid-filling hoses 409 are simultaneously connected to a four-way pipe 410, and the input end of the four-way pipe 410 is tightly connected to a main liquid-filling pipe 403. One end of the main liquid-filling pipe 403 is connected to a paint storage tank 402. In the painting mechanism 4, a motor 414 can drive one of the support rods 407 to rotate, and through the meshing of two half-gears 413, it can drive two symmetrically arranged spray guns 406 to synchronously spray outwards or inwards. By changing the spray range and adjusting the paint flow rate of each spray gun 406 through multiple flow regulating valves 408 to change the spray range of the spray gun 406, the spraying efficiency of the spray gun 406 can be effectively improved while ensuring that the spray gun 406 in the middle can spray normally. In this structure, the spray range of workpieces of different volumes can be met by selecting the use of two other spray guns 406, adjusting their spray angle and adjusting the spray range, and increasing the spray thickness by changing the spray angle so that the spray points of the three spray guns 406 are in the same position.

[0040] Reference Figure 2 In a preferred embodiment, the drying mechanism 1 includes a mounting plate 102, on which multiple guide fans 103 are mounted simultaneously. A movable carbon filling plate 6 is provided in the paint spraying chamber 3 on the opposite side of the guide fans 103, and a thermometer 7 is provided at the bottom of the mounting plate 102.

[0041] Reference Figure 2 In a preferred embodiment, a support plate 105 is tightly fastened to the inner wall of the paint spraying chamber 3 on the opposite side of the activated carbon filling plate 6. A plurality of suction pipes 104 are fixedly connected to the support plate 105, with the suction end of the suction pipes 104 facing downward. The output ends of the plurality of suction pipes 104 are simultaneously connected to a filter 106, and the output end of the filter 106 is connected to a high-temperature incinerator 101.

[0042] Reference Figure 2In a preferred embodiment, one outer wall of the high-temperature incinerator 101 is heat-conducting, and this heat-conducting side is connected to the heat conduction adjustment mechanism 2. The other side of the heat conduction adjustment mechanism 2 is connected to a radiator 107, whose position corresponds to the air inlet of multiple guide fans 103. When the workpiece is conveyed by the painting mechanism 4 to the mounting plate 102 via the conveyor belt 5, the exhaust gas generated during painting is sequentially drawn into the filter 106 and the high-temperature incinerator 101 through the suction pipe 104 for exhaust gas treatment. At this time, the exhaust gas inside the high-temperature incinerator 101... The temperature is maintained within 250℃-300℃. Heat is conducted through the heat-conducting side of the high-temperature incinerator 101, and the temperature is regulated by the heat conduction regulating mechanism 2. The high temperature is dissipated into the paint spraying chamber 3 through the radiator 107, and the hot air is driven by the guide fan 103 to act on the outside of the workpiece. At the same time, the activated carbon filling plate 6 reduces the humidity of the air inside the paint spraying chamber 3 and absorbs the odor in the exhaust gas. This allows for efficient drying of the paint spraying while treating the exhaust gas, thus improving work efficiency.

[0043] Reference Figure 3 In a preferred embodiment, the heat conduction adjustment mechanism 2 includes a heat insulation cover 207, and a plurality of heat conduction plates 206 are fixedly connected at equal density inside the heat insulation cover 207. A heat insulation plate 204 is fixedly connected to the top of each heat conduction plate 206, and the radiator 107 is fixed to the outer wall of the outermost heat conduction plate 206.

[0044] Reference Figure 3 In a preferred embodiment, heat-conducting blocks 205 are tightly and movably connected within adjacent heat-conducting plates 206, and each heat-conducting block 205 is connected to a telescopic rod 203 at its top end. Multiple telescopic rods 203 are simultaneously fixed to the inner top wall of the heat insulation cover 207.

[0045] Reference Figure 3 In a preferred embodiment, one inner wall of the heat insulation cover 207 is tightly connected with an argon gas delivery pipe 202, and each argon gas delivery pipe 202 corresponds to the gap position between two adjacent heat conduction plates 206. Multiple argon gas delivery pipes 202 are simultaneously connected to an argon gas delivery machine 201.

[0046] Reference Figure 5 A highly efficient painting method includes the following specific steps:

[0047] S1: Equipment debugging: Adjust the values ​​of the painting mechanism 4 and the heat conduction adjustment mechanism 2 according to the processing requirements;

[0048] S2: Start Equipment: Start the overall painting equipment;

[0049] S3: Spray painting: The spray painting mechanism 4 sprays paint on the exterior of the workpieces conveyed on the conveyor belt 5;

[0050] S4: Drying: The workpieces on the conveyor belt 5 are dried using the drying mechanism 1;

[0051] S5: Waste gas treatment: While the drying process is underway, the waste gas generated during the painting process is treated by a high-temperature incinerator 101 and a filter 106.

[0052] Reference Figure 5 S1, the debugging of the equipment includes the following specific steps:

[0053] S11: Input workpiece values: Scan the workpiece or directly input the workpiece specifications to obtain the workpiece's specification values;

[0054] S12: Adjusting the spraying mechanism: Automatically adjust the opening and closing angles of two spray guns 406 in the spraying mechanism 4 according to the obtained workpiece specification values, and adjust the spraying range of the spray guns 406 by adjusting the flow regulating valve 408.

[0055] S13: Temperature measurement: Open the high-temperature incinerator 101 and obtain the internal temperature of the paint spraying chamber 3 through the thermometer 7;

[0056] S14: Adjusting the heat conduction adjustment mechanism: Adjust the heat conduction efficiency of the heat conduction adjustment mechanism 2 according to the obtained temperature value. When the temperature inside the paint spraying chamber 3 is increased by heat conduction through the high-temperature incinerator 101, the internal temperature is measured by the thermometer 7. When the measured internal temperature is too high, the heat conduction block 205 can be lifted to the position of the heat insulation plate 204 by controlling different numbers of telescopic rods 203, canceling the heat conduction path between two adjacent heat conduction plates 206, and transporting it to the gap through the argon gas conveyor 201 and the argon gas conveying pipe 202. The filled argon gas plays a certain role in heat insulation, reducing the heat conduction efficiency, thereby reducing the temperature of the heat dissipated by the radiator 107. This ensures efficient drying while also preventing the paint surface from cracking due to excessive temperature inside the paint spraying chamber 3, thus ensuring the painting effect.

[0057] Working principle: During the processing, the painting mechanism 4 can drive one of the support rods 407 to rotate via the motor 414, and through the meshing of two half gears 413, drive the two symmetrically arranged spray guns 406 to synchronously change the spray range by moving outward or inward. Multiple flow regulating valves 408 are used to differentiate and adjust the paint flow rate of each spray gun 406 to change the spray range of the spray gun 406. Thus, while ensuring the normal painting of the spray gun 406 in the middle, this structure allows for the selection of the other two spray guns 406, adjustment of their spray angles, and adjustment of the spray pattern. The spraying range is designed to meet the single spraying range of workpieces of different volumes, and the spraying thickness is increased by changing the spraying angle so that the spraying points of the three spray guns 406 are in the same position, thereby effectively improving the painting efficiency. When the workpiece is conveyed by the painting mechanism 4 to the mounting plate 102 via the conveyor belt 5, the exhaust gas generated during painting is sequentially drawn into the filter 106 and the high-temperature incinerator 101 through the suction pipe 104 for exhaust gas treatment. At this time, the temperature inside the high-temperature incinerator 101 is maintained within 250℃-300℃. The heat-conducting gas inside the high-temperature incinerator 101... Heat is conducted through the side, and the temperature is regulated by the heat conduction regulating mechanism 2, allowing the high temperature to be dissipated into the paint spraying chamber 3 through the radiator 107. Under the action of the guide fan 103, the hot air is driven to act on the outside of the workpiece. At the same time, under the action of the activated carbon filling plate 6, the humidity inside the paint spraying chamber 3 is reduced, and odors in the exhaust gas are also absorbed. This achieves efficient drying of the paint spraying by making full use of the heat energy during exhaust gas treatment, thereby improving work efficiency. When the temperature inside the paint spraying chamber 3 is increased by heat conduction through the high-temperature incinerator 101, the internal temperature is monitored by the thermometer 7. The temperature is measured. When the internal temperature is too high, the heat-conducting block 205 can be lifted to the position of the heat insulation plate 204 by controlling different numbers of telescopic rods 203. This cancels the heat conduction path between two adjacent heat-conducting plates 206. The heat is then transported to the gap through the argon gas conveyor 201 and the argon gas conveying pipe 202. The argon gas filling provides a certain heat insulation effect, reduces the heat conduction efficiency, and thus reduces the temperature of the heat dissipated by the radiator 107. This ensures efficient drying while also preventing the paint surface from cracking due to excessively high temperature in the paint spraying chamber 3, thus ensuring the painting effect.
