Description

Technical Field

[0001] The invention relates to the technical field of electrophoretic coating blowing and drying mechanisms, and in particular to a blowing and drying mechanism for a fully automatic electrophoretic coating production line for manufacturing excavators. Background Art

[0002] Electrophoretic coating is a coating method that uses an external electric field to direct the migration of pigments, resins and other particles suspended in the electrophoretic liquid and deposit them on the surface of the substrate of one of the electrodes. The resin contained in the cathode electrophoretic coating has alkaline groups, which are soluble in water after acid neutralization and salt formation. After direct current is passed, the acid radical negative ions move toward the anode, and the resin ions and the pigment particles wrapped in them move toward the cathode with positive charge and are deposited on the cathode. This is the basic principle of electrophoretic coating, which is the most cost-effective construction process for water-based coatings. It has the characteristics of water solubility, non-toxicity, and easy automation control. It has been widely used in the automotive, building materials, hardware, home appliances and other industries.

[0003] The electrophoretic coating process generally consists of four main processes: pretreatment before coating, electrophoretic coating, post-electrophoretic cleaning, and drying of the electrophoretic coating film. Before drying the coating film, the cleaning water on the surface of the coated part needs to be thoroughly blown dry, otherwise it will cause bulging on the surface of the coated part or leave permanent water stains on the surface, affecting the life and appearance quality of the coated part.

[0004] After the existing excavator parts are electrophoretically coated, most of the drying mechanisms dry their surfaces manually. While drying the surfaces manually, due to the irregular structure of some parts of the excavator, some hidden parts are not dried, resulting in omissions. In addition, since the excavator parts are large, water droplets are widely distributed on the surface, which makes it difficult to quickly dry some surfaces. Sometimes, the next step is performed directly. At the same time, when there is a lot of moisture left on the surface of the excavator parts, it takes a long time to dry them, which affects the working efficiency and leads to a decline in production capacity.

[0005] Therefore, the present application provides a blowing mechanism for a fully automatic electrophoretic coating production line for excavator manufacturing to meet the needs. Summary of the invention

[0006] The technical problem to be solved by the present invention is: after the existing excavator parts are electrophoretically coated, most of the drying mechanisms dry their surfaces manually. While the surfaces are being dried manually, due to the irregular structure of some parts of the excavator, more concealed parts are not dried, resulting in omissions. In addition, since the excavator parts are large, water droplets are widely distributed on the surface, which makes it difficult to quickly dry some surfaces. Sometimes, the next step is performed directly. At the same time, when there is a lot of moisture left on the surface of the excavator parts, it takes a long time to dry them, which affects the working efficiency and leads to a decline in production capacity.

[0008] Optionally, a threaded column is installed at the output end of the servo motor, and the threaded column is rotatably connected to the inner wall of one side of the body. There are two groups of threaded columns, and the two groups of threaded columns are symmetrically distributed on both sides of the inner wall of the body.

[0009] Optionally, the jet assembly includes an integrated frame, which is installed at the bottom of the machine body. The integrated frame is arranged to form multiple groups of cavities of the same size. An air duct is installed inside the integrated frame. The outer surface of the air duct is fitted with the internal cavity of the integrated frame to form a closed space. The air duct is provided in multiple groups and is arranged at equal intervals inside the integrated frame.

[0010] Optionally, a nozzle is provided at the output end of the air duct, and the nozzle heads are provided in multiple groups. The multiple groups of nozzle heads are equidistantly installed at the output end of the air duct, and the output ends of the multiple rows of nozzle heads all produce an inclined effect on the surface of the excavating arm, and an air discharge duct is provided at the lower end of the air duct.

[0011] Optionally, the suction and drainage assembly includes a water suction roller, which is installed at the bottom of the inner wall of the ventilation duct, and the interior of the water suction roller is provided with multiple groups of inclined water diversion channels, and the surface of the water suction roller is provided with a water guide groove, and the bottom of the water guide groove is connected to the water diversion channel.

[0012] Optionally, a collodion bag is installed on one side of the water-absorbing roller, the interior of the collodion bag is a cavity, and a water-absorbing strip is arranged on one side edge of the collodion bag.

[0013] Optionally, a pressure rod is arranged above the water-absorbing roller, a limiting seat is arranged at one end of the pressure rod, and the top of the limiting seat is in contact with the inner wall of the ventilation duct.

[0014] Optionally, a spring is installed on the top surface of one end of the pressure rod, and the top end of the spring is connected to the inner wall of the ventilation duct, and the position of the spring is set on the inner side of the limit seat.

[0015] Optionally, the wheelbase adjustment assembly includes a step wheel, which is installed at one end of the water suction roller, the position of the step wheel is consistent with the movement trajectory of the rack ruler, the internal thread of the step wheel is connected to a reciprocating screw, and one side of the reciprocating screw is installed on the inner wall of the slide slot strip.

[0016] Optionally, a gear is meshedly connected to the surface of the step wheel, a rotating shaft is installed on one side of the gear, and one end of the rotating shaft slides with the inner limit of the slide slot clamping strip.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up the jet assembly and utilizing the cooperation between the integrated frame, the air duct, the jet head and the ventilation duct, when the excavating arm or other parts pass through the conveyor through the hanging rail and the crawler track, the fixed air duct on the integrated frame will guide the wind blown out by the blower to the jet head through the closed space formed by the fit between the air duct output end and the tail of the air duct, and then the gas is compressed into a wind column by the jet head to continuously blow air on the surface of the excavator, and the blower is controlled by the servo motor to raise and lower the threaded rod, and the air ducts are matched one by one with air ducts of different heights, and the wind is sprayed onto the surface of the excavator through multiple groups of jet heads with different inclination angles, so that the moisture on the surface is gradually blown downwards, and due to the change of the angle of the jet head and the change of wind direction, the moisture in the more hidden parts of the excavator parts is also blown out to the surface, and the parts with more moisture will gradually blow the moisture to the bottom until they are separated from the surface, thereby achieving the effect of air drying.

[0018] By setting a rack ruler, the gear is driven to expand and contract the rubber-cotton bag. Under the influence of the wind output by the downwind duct, the rubber-cotton bag continues to fan toward the surface of the excavator parts and contact each other in a large range, absorbing the moisture it contacts. When the rack ruler rises, it drives the gear to shrink and roll up the rubber-cotton bag, which is rolled on the water-absorbing roller and continuously squeezed by the pressure rod. The absorbed moisture flows into the water guide trough and is discharged from the inclined water diversion channel through one side of the water-absorbing roller. The moisture is absorbed to avoid the accumulation of moisture on the surface, speed up the air drying, improve the efficiency of blowing, and speed up the output of production capacity.

[0019] By setting the wheelbase adjustment component, using the step wheel, reciprocating screw, gear, rotating shaft and slide strip, the water suction and drainage component can be operated. Different excavator parts are of different sizes. The fixed length of the water absorption strip can easily make it difficult to absorb the moisture on some surfaces. The step wheel is driven to rotate on the reciprocating screw by the movement of the rack ruler. Due to the different size and diameter of the step wheel, the output end of the gear box on the water absorption roller will move, thereby increasing the moving distance of the cotton bag and the moving distance of the water absorption strip. Therefore, the moisture in some farther parts can be quickly absorbed, and the speed of drying can be accelerated at the same time. It is suitable for drying parts of different models and sizes, thereby improving work efficiency and avoiding long-term contact of workers, thus ensuring the health of workers.

[0029] like Figures 1 to 13 As shown, an embodiment of the present invention provides a drying mechanism for a fully automatic electrophoretic coating production line for manufacturing excavators, comprising a base 1, a bracket 2 is installed on the top of the base 1, a crawler 3 is arranged on the surface of the bracket 2, a motor 4 is installed on the lower right side of the bracket 2, a body 5 is installed on the top of the bracket 2, a slide rail 9 is installed on the top inner wall of the body 5, a lifting claw 10 is slidably connected inside the slide rail 9, an excavating arm 11 is installed at the bottom of the lifting claw 10, a servo motor 12 is installed on the top of the body 5, a threaded column 16 is arranged on the inner wall of one side of the body 5, a threaded sleeve 15 is threadedly connected to the surface of the threaded column 16, and the threaded sleeve An air duct 14 is provided on one side of 15, a blower 13 is installed at one end of the air duct 14, and rack rulers 17 are provided on both sides of the end of the air duct 14; a jet assembly 6 is provided at the bottom of the body 5, and the jet assembly 6 is used to dry the moisture on the surface of the excavating arm 11 at different angles; a suction and drainage assembly 7 is installed under the jet assembly 6, and the suction and drainage assembly 7 is used to actively absorb the moisture of the excavating arm 11; a wheelbase adjustment assembly 8, a wheelbase adjustment assembly 8 is provided at one end of the jet assembly 6, and the wheelbase adjustment assembly 8 is used to extend and scale the suction and drainage assembly 7 to different positions.

[0030] As an implementation method in this embodiment, Figures 4 to 9As shown, a threaded column 16 is installed at the output end of the servo motor 12, and the threaded column 16 is rotatably connected on the inner wall of one side of the body 5, and there are two groups of threaded columns 16, and the two groups of threaded columns 16 are symmetrically distributed on both sides of the inner wall of the body 5. The jet assembly 6 includes an integrated frame 61, which is installed at the bottom of the body 5. The integrated frame 61 is arranged as multiple groups of cavities of the same size, and an air duct 62 is installed inside the integrated frame 61. The outer surface of the air duct 62 fits with the internal cavity of the integrated frame 61 to form a closed space. There are multiple groups of air ducts 62, which are arranged and installed inside the integrated frame 61 at equal intervals. A jet head 63 is provided at the output end of the air duct 62, and there are multiple groups of jet heads 63. Multiple groups of jet heads 63 are equidistantly installed at the output end of the air duct 62, and the output ends of the multiple rows of jet heads 63 all produce an inclined effect on the surface of the excavating arm 11, and a ventilation duct 64 is provided at the lower end of the air duct 62.

[0031] In this embodiment, when the servo motor 12 is started, the threaded column 16 is controlled to rotate while the air duct 14 is moved. At the same time, the tail of the air duct 62 on the integrated frame 61 intersects with the output end of the air duct 14 to form a closed space. At the same time, the air duct 62 guides the wind to the nozzle 63, and then the wind is sprayed to the surface of the excavation arm 11 through the nozzle 63. The multiple rows of nozzles 63 blow the moisture on the surface of the excavation arm 11 to the bottom layer by layer, expanding the contact area between the moisture and the air while increasing the speed of surface drying. The moisture on the surface will be continuously blown to the bottom through the wind force of different layers of the nozzles 63. The air duct 14 continues to move downward, and when it moves to the tail of the ventilation duct 64, it forms a semi-enclosed space with it, driving the suction and drainage assembly 7 to operate. At the same time, the powerful blowing force of the nozzle 63 blows the moisture in the more hidden parts of the excavator parts out through strong wind, and the hidden parts are dried quickly.

[0032] As an implementation method in this embodiment, Figures 8 to 11 As shown, the suction and drainage assembly 7 includes a water suction roller 71, which is installed at the bottom of the inner wall of the ventilation duct 64. A plurality of inclined water diversion channels 78 are arranged inside the water suction roller 71. A water guide groove 72 is arranged on the surface of the water suction roller 71. The bottom of the water guide groove 72 is connected to the water diversion channel 78. A cotton bag 73 is installed on one side of the water suction roller 71. The interior of the cotton bag 73 is a cavity. A water absorption strip 74 is arranged on one side edge of the cotton bag 73. A pressure rod 75 is arranged above the water suction roller 71. A limiting seat 76 is arranged at one end of the pressure rod 75. The top of the limiting seat 76 is in contact with the inner wall of the ventilation duct 64. A spring 77 is installed on the top surface of one end of the pressure rod 75. The top of the spring 77 is connected to the inner wall of the ventilation duct 64. The position of the spring 77 is arranged on the inner side of the limiting seat 76.

[0033] In this embodiment, when the air duct 14 and the ventilation duct 64 form a semi-enclosed space, the water absorption roller 71 is driven by the rack ruler 17 to rotate the power generated by the step wheel 81, so that the cotton bag 73 extends outward, and the water absorption strip 74 moves outward synchronously. When the output end of the air duct 14 moves to the tail of the ventilation duct 64 and intersects, the wind force is directly output to the inside of the ventilation duct 64, so that the internal cavity of the cotton bag 73 is bulged and fanned. When the cotton bag 73 is fanned, the water absorption strip 74 is fanned to remove the moisture on the surface of the excavating arm 11. Absorption, at the same time, when the rack ruler 17 moves from bottom to top, the water-absorbing roller 71 rotates counterclockwise to wind and recycle the cotton bag 73. When the water-absorbing roller 71 is wrapped, the pressure rod 75 squeezes it, causing the water to be diverted to the water guide trough 72 and flow out through the inclined water diversion channel 78. The use of the spring 77 and the limit seat 76 alleviates the hard damage of the cotton bag 73 to the structure. The use of suction and drainage improves its drying efficiency. At the same time, the reciprocating cotton bag 73 improves the efficiency of absorbing and drying on the assembly line to cope with different excavator parts.

[0034] As an implementation method in this embodiment, Figure 8 and Figures 10 to 13 As shown, the wheelbase adjustment assembly 8 includes a step wheel 81, which is installed at one end of the water-absorbing roller 71. The position of the step wheel 81 is consistent with the movement trajectory of the rack ruler 17. The internal thread of the step wheel 81 is connected to a reciprocating screw 82, and one side of the reciprocating screw 82 is installed on the inner wall of the slide slot strip 85. The surface of the step wheel 81 is meshed with a gear 83, and a rotating shaft 84 is installed on one side of the gear 83. One end of the rotating shaft 84 slides with the internal limit position of the slide slot strip 85.

[0035] In this embodiment, when the suction and drainage assembly 7 is in operation, the wheelbase adjustment assembly 8 rotates at the same time, and the step wheel 81 is divided into a plurality of intervals, each of which has a different diameter of the gear teeth and overlaps with each other, and can be gradually increased or decreased. At the same time, when the step wheel 81 is engaged with the rack ruler 17, the step wheel 81 rotates, and when the rack ruler 17 moves downward, the step wheel 81 reciprocates on the reciprocating screw rod 82. When the rack ruler 17 moves from bottom to top, the step wheel 81 rotates counterclockwise and moves in one direction, and then The gear 83 meshing with the heel step wheel 81 rotates. When the gear 83 rotates, it drives the water absorption roller 71 to rotate, and the rotating shaft 84 rotates at the same time. When the rotating shaft 84 rotates, it is driven by the rotation of the step wheel 81 to drive the gear 83 to move on the slide bar 85, and adjust its own wheelbase distance to extend the moving distance of the water absorption bar 74, so that it can absorb moisture on the surface of parts of different sizes through its own moving distance, speed up the drying speed, and improve production capacity.

[0036] The working principle provided by the present invention is to first check whether the base 1 is stable, start the crawler 3 on the top bracket 2 of the base 1 through the motor 4, and at the same time start the slide rail 9 on the top of the body 5, move the excavating arm 11 that has just been electrophoretically coated into the cavity of the body 5 through the lifting claw 10, and then start the blower 13. After the blower 13 is started, the output end transmits the wind through the air duct 14, and starts the servo motor 12. The servo motor 12 controls the threaded column 16 to rotate, and then the threaded sleeve 15 is moved by the rotation of the threaded column 16, and the screw When the sleeve 15 moves, it drives the air duct 14 to move. When the air duct 14 moves, the output end intersects with the jet assembly 6 first. At this time, the tail of the air duct 62 on the integrated frame 61 intersects with the output end of the air duct 14 to form a closed space. The air duct 62 guides the wind to the jet head 63, and then the wind is sprayed to the surface of the excavating arm 11 through the jet head 63 to dry the moisture on the surface of the excavating arm 11. The moisture on the surface will be blown downward by the wind force of the jet head 63, and the air duct 14 continues to move downward.

[0037] When it moves to the tail of the ventilation duct 64, it forms a semi-enclosed space with it. The powerful blowing force of the nozzle 63 blows the moisture in the more hidden parts of the excavator parts to the surface. The parts with less moisture can be quickly dried by the blowing of the nozzle 63, and the parts with more moisture on the surface will blow the moisture to the bottom layer by layer until it is separated from the surface, thereby achieving the effect of drying. Then, while the air duct 14 moves downward, the rack ruler 17 moves downward synchronously, and the step wheel 81 on its moving trajectory contacts the rack ruler 17 to rotate, starting the suction and drainage assembly 7, and then the water absorption roller 71 rotates, the cotton bag 73 unfolds outward, and the water absorption strip 74 moves outward synchronously. When the output end of the air duct 14 intersects with the tail of the ventilation duct 64, the wind force is directly output to the inside of the ventilation duct 64, causing the cotton bag 73 to blow.

[0038] When the cotton bag 73 is fanning, the water absorption strip 74 is fanning to absorb the water on the surface of the excavating arm 11, avoiding the accumulation of water on the surface, accelerating the air drying speed and improving the drying efficiency. When the rack ruler 17 continues to move, the wheelbase adjustment assembly 8 rotates, and the step ladder wheel 81 is meshed with the rack ruler 17, and the step ladder wheel 81 rotates. At the same time, the step ladder wheel 81 reciprocates on the reciprocating screw rod 82, and then the gear 83 meshed with the step ladder wheel 81 rotates. When the gear 83 rotates, the water absorption roller 71 is driven to rotate, and the rotating shaft 84 on the other side rotates. When the rotating shaft 84 rotates, the gear 83 is driven on the slide slot card strip 85 to move outward, the moving distance of the cotton bag 73 is lengthened, thereby lengthening the moving distance of the water absorption strip 74, and making different The moisture on the surface of the parts of the excavator can be quickly absorbed, the speed of moisture absorption is accelerated, and the speed of drying is accelerated, thereby improving the working efficiency. When the air duct 14 moves from the top to the bottom, and then moves from the bottom to the top, when the rack ruler 17 continues to contact the step wheel 81, it rotates inward to roll up and retract the rubber cotton bag 73 and the water-absorbing strip 74. When the rubber cotton bag 73 is wound on the water-absorbing roller 71, it is squeezed by the pressure rod 75 and acts on the spring 77 to move in the limit seat 76. The squeezed water will flow to the water diversion channel 78 through the water guide groove 72, and flow out of the water-absorbing roller 71 through the inclined water diversion channel 78. When the parts of the excavator are electrophoretically coated, the accumulation of moisture on the surface is avoided, and the speed of air drying is accelerated, the efficiency of drying is improved, and the output of production capacity is accelerated. At the same time, while accelerating the drying speed, the working efficiency is improved, and the workers' long-term contact is avoided, thereby ensuring the workers' physical health.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
