DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0024] The embodiments of the present application provide an aluminum profile vertical spraying production line and a use method, which can solve the problem that in the related art, after the aluminum profile completes single spraying, it needs to be returned to enter the feeding / discharging area again, which greatly increases the production cycle and reduces the overall production efficiency.

[0025] Please refer to Figures 1-3 An aluminum profile vertical spraying production line, comprising: oppositely arranged frame bodies 1, which have oval tracks 2 thereon; A suspended conveying unit 3 arranged on the oval track 2; A spraying bin 6 arranged below one side of the suspended conveying unit 3; A plurality of clamping units 4 arranged equidistantly on the suspended conveying unit 3, the clamping units 4 being used for clamping aluminum profiles; The suspended conveying unit 3 is used for driving the plurality of clamping units 4 to rotate along the oval track 2, so as to control the aluminum profiles to enter / leave the spraying bin 6 in turn; Two groups of spraying mechanisms 5 oppositely arranged in the spraying bin 6 and used for spraying the clamped aluminum profiles on the clamping units 4.

[0026] The aluminum profile to be sprayed is placed in the loading area near the production line.

[0027] The frame body 1 provides a stable support structure for the entire production line, and the elliptical track 2 is the running path of the hanging conveying unit 3. At this time, the hanging conveying unit 3 is in the initial position, and the aluminum profiles are clamped one by one on the multiple clamping units 4 arranged at equal intervals on the hanging conveying unit 3.

[0028] The hanging conveying unit 3 is started, and the hanging conveying unit 3 starts to rotate along the elliptical track 2. Since the multiple clamping units 4 are arranged at equal intervals on the hanging conveying unit 3, as the hanging conveying unit 3 moves, the clamping units 4 will drive the aluminum profiles to move along the elliptical track 2.

[0029] When the aluminum profiles move with the hanging conveying unit 3 to the side below the spraying cabin 6, the aluminum profiles will enter the spraying cabin 6 in turn. The spraying cabin 6 is arranged below the side of the hanging conveying unit 3, providing a relatively closed and controllable environment for the spraying operation.

[0030] After the aluminum profiles enter the spraying cabin 6, the two groups of spraying mechanisms 5 start to work, and the two groups of spraying mechanisms 5 work in turn in front of and behind the clamping units 4 to comprehensively spray the aluminum profiles clamped on the clamping units 4.

[0031] After the spraying operation is completed, the hanging conveying unit 3 continues to move along the elliptical track 2, driving the aluminum profiles to move away from the spraying cabin 6. When the aluminum profiles move to the appropriate unloading position, the operator takes the sprayed aluminum profiles off the clamping units 4, completing the entire spraying production process. After that, the hanging conveying unit 3 continues to circulate and operate, and the next batch of aluminum profiles is sprayed, realizing the continuity and efficiency of production.

[0032] By adopting the elliptical track 2, compared with the traditional straight line conveying track, the horizontal space occupied by the equipment in the factory is greatly reduced. The elliptical track can realize the circulation of the aluminum profiles in a relatively compact area, making the equipment layout more compact and reasonable, and improving the utilization rate of the factory space.

[0033] Through the continuous rotation of the hanging conveying unit 3 along the elliptical track 2, the aluminum profiles do not need to perform complex return operations after spraying, but can directly continue to move along the elliptical track, reducing the waiting time in the production cycle. At the same time, multiple clamping units 4 are arranged at equal intervals on the hanging conveying unit 3, realizing the continuous loading, spraying and unloading of the aluminum profiles, and further improving the overall production efficiency.

[0034] The spraying mechanism 5 can comprehensively spray the aluminum profile from different directions, ensuring that each surface of the aluminum profile can uniformly receive paint spraying, effectively avoiding the problems of dead angle and uneven spraying, improving the spraying quality of the aluminum profile, making it have better corrosion resistance and decorative properties, and enhancing the competitiveness of the product in the market.

[0035] As shown in Figure 1 and Figure 2 In one embodiment, the hanging conveying unit 3 includes a sprocket 31 rotatably arranged on the frame body 1, two sprockets 31 are drivingly connected with a conveying chain 32 located below the elliptical track 2, and a driving member 33 is arranged on one side of the frame body 1 and connected with one side of the sprocket 31 for driving the conveying chain 32 to rotate.

[0036] Among them, two bearing seats are oppositely arranged on the frame body 1, a rotating shaft is arranged between the two bearing seats on the same side, and the sprocket 31 is arranged on the rotating shaft, and the top end of the rotating shaft extends to the outside of the upper bearing seat.

[0037] The driving member 33 includes a driving motor and a speed reducer arranged on one side of the frame body 1, the output shaft of the driving motor is connected with the input shaft of the speed reducer, and the input shaft of the speed reducer is connected with the top end of one side of the rotating shaft.

[0038] The driving member 33 is installed on one side of the frame body 1 and is composed of a driving motor and a speed reducer, the output shaft of the driving motor is tightly connected with the input shaft of the speed reducer, and the output shaft of the speed reducer is connected with the top end of one side of the rotating shaft. When the power is turned on, the driving motor starts to operate, and the rotating power generated by the driving motor is transmitted to the speed reducer through the output shaft.

[0039] The speed reducer reduces the high-speed rotation of the driving motor and increases the torque, and then transmits the processed power to the rotating shaft connected thereto through the output shaft. Since the sprocket 31 is arranged on the rotating shaft, the rotation of the rotating shaft will drive the sprocket 31 to rotate synchronously.

[0040] When one sprocket 31 starts to rotate under the action of the driving member 33, it will drive the other sprocket 31 to rotate through the meshing transmission of the chain, so as to make the whole conveying chain 32 make a circular rotating motion along the track of the elliptical track 2.

[0041] The bottom of the conveying chain 32 is equidistantly provided with a plurality of fixed rods 34, the fixed rods 34 provide stable connection points for the clamping units 4, the clamping units 4 are connected with the corresponding fixed rods 34, and with the rotation of the conveying chain 32, the fixed rods 34 will drive the clamping units 4 to move along the elliptical track 2.

[0042] The driving member 33 uniformly distributes power to the two sprockets 31 through the reducer, so that the conveying chain 32 is uniformly stressed during operation. This uniform power distribution avoids problems such as stretching and wear of the chain due to excessive local stress, prolongs the service life of the chain and sprocket, and reduces the maintenance cost of the equipment.

[0043] The driving motor in the driving member 33 achieves stepless speed regulation through a frequency converter or other control equipment. The operator can flexibly adjust the rotation speed of the conveying chain 32 according to different production requirements, such as the specifications of aluminum profiles, spraying process requirements, etc., thereby controlling the conveying speed of the aluminum profiles. This adjustability enables the production line to adapt to various production scenarios, improving the versatility and flexibility of the production line.

[0044] As shown in Figure 3 and Figure 9 , in one embodiment, the conveying chain 32 is adapted to the oval track 2 and is also oval-shaped. The conveying chain 32 is formed by a plurality of articulated units, and each articulated unit includes a pin shaft with two chain plates rotatably arranged on the pin shaft, and a through hole provided at the other end of the chain plate.

[0045] The conveying chain 32 is composed of a plurality of articulated units. The two chain plates in each articulated unit are connected by a pin shaft for relative rotation, so that adjacent articulated units can flexibly rotate relative to each other, thereby giving the conveying chain 32 good flexibility and bendability.

[0046] The through hole provided at the other end of the chain plate facilitates the connection of the pin shaft, ensuring that the chain can be stably constructed into a complete oval structure and adapted to the oval track 2.

[0047] As shown in Figure 1 , Figure 2 and Figure 3 , the hanging conveying unit 3 in the present embodiment further includes a guide end 35 connected to the top end of the fixed rod 34; a slide 21 is formed above the oval track 2, and a through hole 22 is provided at the bottom of the slide 21; the guide end 35 includes a fixed plate 351 arranged in the slide 21, and a pulley 352 rotatably arranged on both sides of the fixed plate 351, the pulley 352 being in sliding cooperation with the slide 21, and the top end of the fixed rod 34 penetrating through the through hole 22 and being connected to the corresponding fixed plate 351.

[0048] During assembly of the hanging conveying unit 3, the fixed plate 351 of the guide end 35 is arranged in the slide 21 formed above the oval track 2, and the top end of the fixed rod 34 is inserted through the through hole 22 provided at the bottom of the slide 21 and connected to the fixed plate 351, thereby completing the preliminary assembly of the guide end 35, the fixed rod 34, and the oval track 2.

[0049] When the driving member 33 is started, the driving motor transmits power to the chain wheel 31 through the speed reducer, the chain wheel 31 is engaged with the conveying chain 32 to drive the conveying chain 32 to make a circulating rotary motion along the elliptical track 2. Since the fixed rod 34 is connected with the bottom of the conveying chain 32, and the guide end 35 is connected with the fixed rod 34 through the fixed plate 351, the movement of the conveying chain 32 will drive the fixed rod 34 and the guide end 35 to move together.

[0050] During the movement of the guide end 35, the pulley 352 is in sliding fit with the slide 21, and the pulley 352 rolls in the slide 21 to convert the sliding friction between the guide end 35 and the slide 21 into rolling friction, so that the guide end 35 can move more smoothly in the slide 21, thereby driving the fixed rod 34 and the clamping unit 4 to operate stably, and ensuring that the aluminum profile clamped on the clamping unit 4 can accurately and stably enter and leave the spraying cabin 6 according to the predetermined track, and complete the spraying work.

[0051] The guide end 35 is connected with the fixed rod 34 through the fixed plate 351, and slides in the slide 21 by using the pulley 352, which can better disperse the load borne by the fixed rod 34. Even if the clamping unit 4 clamps a relatively heavy aluminum profile, the guide end 35 can also uniformly transmit the load to the elliptical track 2 through the pulley 352, so as to avoid local stress concentration, thereby improving the carrying capacity of the entire suspension conveying unit 3, and making it adapt to the spraying production requirements of aluminum profiles of different specifications and weights.

[0052] The slide 21 guides the movement of the guide end 35, so that the guide end 35 can strictly operate according to the predetermined elliptical track.

[0053] As shown in Figure 3 , Figure 4 and Figure 5 , in one embodiment, the clamping unit 4 comprises: a rotating member 41 connected with the fixed rod 34; and a clamping jaw 42 connected with the rotating member 41, the clamping jaw 42 being used for clamping the aluminum profile, and the rotating member 41 being used for driving the clamping jaw 42 to rotate.

[0054] The clamping jaw 42 firmly clamps the aluminum profile, the conveying chain 32 operates to drive the clamping jaw 42 clamping the aluminum profile to move along the elliptical track 2 towards the spraying cabin 6.

[0055] After entering the spraying cabin 6, according to the preset spraying process requirements, the rotating member 41 starts to work, and the driving clamping jaw 42 in the rotating member 41 drives the aluminum profile to rotate.

[0056] During the rotation of the aluminum profile, the surfaces of the aluminum profile are uniformly sprayed. After the spraying work is completed, the conveying chain 32 drives the clamping unit 4 out of the spraying cabin 6 and to a designated unloading position.

[0057] As Figure 4 and Figure 5 Specifically, the clamping jaw 42 includes an electric push rod 42.1 arranged at the bottom of the rotating part 41, a mounting plate 42.2 arranged on the electric push rod 42.1, and a lifting disc 342.3 arranged at the bottom end of the piston rod of the electric push rod 42.1. First connecting rods 42.4 are hingedly arranged at the two sides of the mounting plate 42.2, and the first connecting rods 42.4 are V-shaped. Clamping pieces 42.5 are arranged at the bottom ends of the first connecting rods 42.4. Second connecting rods 42.6 are rotatably arranged at the two sides of the lifting disc 342.3. Pin shafts 42.7 are rotatably connected to the middle parts of the first connecting rods 42.4. The other two ends of the two second connecting rods 42.6 on the same side are respectively connected to the two ends of the corresponding pin shafts 42.7.

[0058] When the clamping operation is not started, the electric push rod 42.1 is in a retracted state. The piston rod pulls the lifting disc 342.3 to a higher position. The second connecting rods 42.6 exert an inward force on the pin shafts 42.7. The clamping pieces 42.5 at the bottom ends of the two first connecting rods 42.4 are close to each other, forming a closed state.

[0059] When it is necessary to clamp the aluminum profile, the control system issues an instruction, and the electric push rod 42.1 starts to extend. The piston rod pushes the lifting disc 342.3 to move downward. With the downward movement of the lifting disc 342.3, the second connecting rods 42.6 exert an outward force on the pin shafts 42.7 in the middle parts of the first connecting rods 42.4, driven by the lifting disc 342.3. The first connecting rods 42.4 are hingedly connected to the mounting plate 42.2. This force makes the first connecting rods 42.4 rotate around the hinge points. The clamping pieces 42.5 at the bottom ends of the two first connecting rods 42.4 gradually move away from each other, thereby leaving enough space for placing the aluminum profile.

[0060] After the aluminum profile is placed in the space between the two clamping pieces 42.5, the control system issues an instruction again. The piston rod of the electric push rod 42.1 pushes the lifting disc 342.3 to retract upward. With the upward movement of the lifting disc 342.3, the second connecting rods 42.6 pull the pin shafts 42.7 to move inward, thereby making the first connecting rods 42.4 reversely rotate around the hinge points. The clamping pieces 42.5 at the bottom ends of the two first connecting rods 42.4 gradually move close to each other, finally clamping the aluminum profile, thereby providing stable clamping for subsequent rotation and spraying operations.

[0061] The position of the lifting disc 342.3 is controlled by the electric push rod 42.1, thereby accurately adjusting the opening and closing degree of the clamping pieces 42.5 and the clamping force. This can ensure that the clamping pieces 42.5 always exert a stable and appropriate clamping force on the aluminum profile during the rotation and spraying of the aluminum profile, effectively preventing the aluminum profile from loosening or falling off, thereby guaranteeing the spraying quality and production safety. Meanwhile, the V-shaped first connecting rods 42.4 increase the stability of clamping.

[0062] As shown in Figure 4 and Figure 5 The rotating part 41 in the embodiment includes a mounting disc arranged at the bottom of the fixed rod 34, the bottom of the mounting disc is provided with a housing, the housing is provided with a speed reducer and a driving motor, the output shaft of the driving motor is connected with the input shaft of the speed reducer, and the output shaft of the speed reducer is connected with the electric push rod 42.1.

[0063] When the whole clamping unit 4 is driven to the designated working position by the conveying chain 32, ready for the rotating spraying operation on the aluminum profile, the control system sends a starting instruction to the driving motor in the rotating part 41, and the driving motor starts to operate, and the output shaft rotates in the set direction and speed.

[0064] The output shaft of the driving motor is connected with the input shaft of the speed reducer, the power generated by the motor rotation is transmitted to the speed reducer, and the speed reducer converts the input high-speed low-torque power through the internal gear transmission mechanism to output low-speed high-torque power.

[0065] The output shaft of the speed reducer is connected with the electric push rod 42.1, and the low-speed high-torque power processed by the speed reducer is transmitted to the electric push rod 42.1, and then drives the whole clamping jaw 42 to rotate, since the clamping jaw 42 has clamped the aluminum profile, the aluminum profile will also rotate with the clamping jaw 42, realizing all-around spraying.

[0066] The rotating part 41 drives the clamping jaw 42 and the aluminum profile to rotate, so that the aluminum profile can receive paint spraying in all directions and uniformly in the spraying process, effectively avoiding the problems of spraying dead angle and uneven coating thickness. Compared with static spraying, the spraying quality of the aluminum profile is greatly improved, the coating is more flat, smooth and uniform, the corrosion resistance and aesthetic degree of the aluminum profile are enhanced, and the market demand for high-quality aluminum profile products is met.

[0067] As shown in Figure 1 and Figure 6 In one embodiment, the spraying cabin 6 has a processing chamber 61 inside for spraying the aluminum profile, and the spraying cabin 6 is provided with a running channel 62 for the aluminum profile to enter and exit the processing chamber 61, and the running channel 62 is in the shape of n.

[0068] The processing chamber 61 is a region defined for the spraying operation of the aluminum profile inside the spraying cabin 6, and the region has a relatively independent space, which can provide a relatively stable and controlled environment for the spraying process, reducing the interference of external factors on the spraying effect.

[0069] The running channel 62 is a channel for the aluminum profile to enter and exit the processing chamber 61, so that the hanging conveying unit 3 can control the clamping unit 4 to freely enter and exit the processing chamber 61.

[0070] As shown in Figure 6 andFigure 7 As shown in one embodiment, two groups of the spraying mechanism 5 are arranged along the length of the spraying chamber 6; the spraying mechanism 5 includes: a lifting member 51 arranged in the processing chamber 61; a spraying part 52 provided on the lifting member 51; a feeding part 53 arranged outside the spraying chamber 6 for supplying liquid to the spraying part 52; a baffle 54 arranged opposite to the spraying part 52, the baffle 54 and the spraying part 52 are located on both sides of the travel channel 62; the lifting member 51 is used to drive the spraying part 52 to ascend and descend.

[0071] When the aluminum profile passes through the travel channel 62 into the processing chamber 61, the lifting member 51 drives the spraying part 52 to ascend to the appropriate position according to the preset program and the height, shape, etc. of the aluminum profile, the feeding part 53 delivers the paint to the spraying part 52, and the spraying part 52 starts to spray paint on the surface of the aluminum profile.

[0072] During the spraying process, the baffle 54 plays a role in blocking the paint, ensuring that the paint is accurately sprayed on the target area of the aluminum profile. As the aluminum profile moves in the travel channel 62, the spraying part 52 continues to perform the spraying operation, completing the spraying of the aluminum profile.

[0073] Since the spraying part 52 can be adjusted in height by the lifting member 51, the spraying mechanism 5 can adapt to aluminum profiles of different heights and shapes, improving the versatility and flexibility of the spraying equipment.

[0074] The arrangement of the baffle 54 helps to guide the spraying direction of the paint, allowing the paint to be more concentrated on the target area of the aluminum profile, reducing waste and splashing of the paint. At the same time, the baffle 54 can form a certain airflow guide, which helps to evenly distribute the paint on the surface of the aluminum profile, improving the uniformity and quality of the spraying.

[0075] As shown in one embodiment, the spraying part 52 includes a support arm 521 arranged on the lifting member 51, a mounting disc 522 connected to the support arm 521, a plurality of spraying pipes 523 arranged equidistantly on the mounting disc 522, a nozzle 524 arranged at one end of the spraying pipe, and a connector 525 arranged at the other end of the spraying pipe. Figure 6 Figure 7 The support arm 521 plays a role in supporting and transmitting force, transmitting power from the lifting member 51 to the mounting disc 522, so that the mounting disc and the spraying pipes 523 thereon can move up and down together with the lifting member, thereby adjusting the distance between the nozzle and the aluminum profile to ensure the spraying effect.

[0076] The support arm 521 plays a role in supporting and transmitting force, transmitting power from the lifting member 51 to the mounting disc 522, so that the mounting disc and the spraying pipes 523 thereon can move up and down together with the lifting member, thereby adjusting the distance between the nozzle and the aluminum profile to ensure the spraying effect.

[0077] ​The installation disc 522 serves as a fixed platform for the spray pipes 523, and the spray pipes 523 are installed through equidistantly arranged installation holes, so that the relative positions between the spray pipes are accurate and stable, and the plurality of nozzles can be uniformly distributed to achieve overall coverage of the surface of the aluminum profile.

[0078] The spray pipe 523 introduces the paint delivered from the feeding part 53 from the joint 525 and delivers the paint to the nozzles 524 to provide stable paint supply for the nozzles, and is a key channel for realizing paint spraying.

[0079] As shown in Figure 6 and Figure 7 , in one embodiment, the lifting member 51 is a vertically arranged electric slide rail, and the support arm 521 is arranged on the sliding seat of the electric slide rail The electric slide rail generally consists of a rail, a sliding seat, a driving motor, a transmission device such as a screw rod, a belt, etc., and a control system, etc. The rail is vertically arranged to provide guidance and support for the up-down movement of the sliding seat; the sliding seat is installed on the rail and can smoothly slide along the rail; the driving motor transmits power to the sliding seat through the transmission device to make it move according to the set speed and stroke; and the control system is used to control the start-stop, forward-reverse rotation and adjustment of the moving speed and other parameters of the motor, which is a prior art and will not be described here.

[0080] The support arm 521 is arranged on the sliding seat of the electric slide rail and is fixed by bolt connection or welding, etc., which can ensure that the support arm moves synchronously with the sliding seat and can adjust the installation position and angle of the support arm on the sliding seat according to actual needs.

[0081] The electric slide rail has high motion accuracy and can realize accurate position control of the sliding seat. During the spraying process, the height of the support arm and the spraying part can be accurately adjusted by the control system to keep the nozzles at a proper distance from the surface of the aluminum profile, thereby ensuring the uniformity and quality of the spraying.

[0082] As shown in Figure 7 and Figure 8 , in this embodiment, the feeding part 53 includes a tank body 531, a pump body 532 is arranged on the tank body 531, the inlet of the pump body 532 communicates with the tank body 531, the outlet of the pump body 532 communicates with a distribution pipe 533, a plurality of feeding pipes 534 are communicated on the distribution pipe 533, a joint two 535 is arranged at the other end of the feeding pipe 534, and the joint two 535 and the joint 525 are communicated through a hose 536.

[0083] The tank body 531 is a closed container, and auxiliary components such as an observation window, a liquid level meter and a feeding port are further arranged on the tank body to facilitate the operator to observe the remaining amount of paint in the tank.

[0084] The pump body 532 is the core power device of the feeding part, which can pump out the paint in the tank body at a certain pressure and flow rate and deliver it to the subsequent distribution pipe 533.

[0085] The distribution pipe 533 distributes the paint delivered by the pump body, so that the paint can be supplied to multiple feeding pipes 534 at the same time, thereby providing paint for multiple spray pipes and realizing simultaneous spraying of multiple nozzles to improve the spraying efficiency.

[0086] The joint two 535 and the joint 525 are usually quick joints or threaded joints, which have the characteristics of good sealing performance and convenient connection.

[0087] The hose 536 is made of rubber material and has certain elasticity and corrosion resistance. The hose 536 plays a buffering and compensating role, can adapt to the position change of the spraying part during lifting, and ensures that the connection between the feeding pipe 534 and the spraying pipe 523 is always stable and reliable.

[0088] As shown in Figure 6 and Figure 10 In another embodiment, two sets of oppositely arranged adsorption mechanisms are further included, which include a gas collecting hood arranged on the side of the baffle 54 away from the travel channel 62 and a fan arranged on the spraying cabin 6. The inlet of the fan is communicated with the gas collecting hood, and the outlet of the fan is communicated with an external pipeline.

[0089] The ground of the processing chamber 61 is provided with a plurality of grooves, and a grid is arranged above the grooves.

[0090] During spraying operation, the paint sprayed on the surface of the aluminum profile will volatilize to produce waste gas. Through the suction action of the fan, the waste gas is transported from the gas collecting hood to the external pipeline through the fan, and finally enters the external waste gas treatment system for purification treatment, thereby reducing the concentration of waste gas in the spraying cabin, improving the working environment, and protecting the health of the operators.

[0091] During spraying operation, part of the paint may drop or splash onto the ground of the processing chamber. These paints will fall into the grooves along the pores of the grid to avoid accumulation of the paints on the ground and maintain the cleanliness of the ground of the processing chamber.

[0092] The grooves can concentrate the collected impurities for regular cleaning. The grid can prevent people from accidentally stepping into the grooves to avoid safety accidents.

[0093] In addition, it should be noted that, in order to facilitate power supply to the equipment, two parallel conductive tracks of conductive alloy strips are arranged inside the elliptical track 2 in the embodiment, which are used as positive and negative electrodes, respectively. The conductive tracks are continuously arranged along the length direction of the track and connected with an external power supply. The conductive tracks and the metal structure of the elliptical track 2 are isolated by insulating materials such as ceramics and epoxy resin to prevent short circuit.

[0094] Two groups of carbon brushes are installed on the fixed plate 351 of the guide end 35, which are in contact with two conductive tracks respectively. The carbon brushes maintain close contact with the tracks through spring pressure to ensure the continuity of power supply. The carbon brushes are connected to the power input end of the rotating part 41 through wires to supply power to the driving motor.

[0095] A slip ring is integrated on the outer shell of the electric push rod 42.1, which consists of a stator fixed part and a rotor rotating part, and realizes continuous power supply during rotation through the brush. The slip ring output end is connected to the power supply interface of the electric push rod 42.1, and the slip ring output end is connected to the carbon brush through wires to supply power to the electric push rod 42.1, ensuring the rotation and opening and closing action of the clamping jaw 42. This is a prior art and will not be described in detail here.

[0096] A method for using an aluminum profile vertical spraying production line, comprising the following process steps: S1: control the clamping unit 4 to firmly clamp the aluminum profile on the clamping jaw 42.

[0097] S2: start the suspension conveying unit 3, drive the clamping unit 4 to rotate along the elliptical track 2, and make the clamping unit 4 clamping the aluminum profile move towards the spraying cabin 6.

[0098] S3: control the lifting part 51 to adjust the height of the spraying part 52, so that the spraying part 52 is in the appropriate spraying position, the feeding part 53 supplies liquid to the spraying part 52, the spraying part 52 sprays the aluminum profile, and the baffle 54 blocks the paint splashing.

[0099] S4: during the spraying process, the rotating part 41 drives the entire clamping jaw 42 to rotate, so that the clamped aluminum profile rotates around its own axis, ensuring that each surface of the aluminum profile can uniformly receive the spraying of the paint.

[0100] S5: when the aluminum profile completes the spraying work, the clamping unit 4 continues to move along the elliptical track 2, and the sprayed aluminum profile is moved out from the other end of the travel channel 62 of the spraying cabin 6, completing the entire spraying production process.

[0101] S6: the operator can take the sprayed aluminum profile from the clamping jaw 42 for subsequent inspection, packaging and other processes.
