[0004] Therefore, in view of the above problems, the present invention proposes a V-shaped powder coating booth device for producing aluminum alloy profiles, which solves the technical problem that existing painting devices cannot recycle the paint that has not been sprayed onto the aluminum surface and is suspended in the air after painting.

[0011] Furthermore, the knob head is provided with a Y-shaped hole for insertion into the Y-shaped head.

[0014] Furthermore, the included angle between the card blocks is 90 degrees, and there is a notch between the card blocks.

[0015] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0016] This V-shaped powder coating booth for producing aluminum alloy profiles utilizes a negative pressure pipe system. A conveyor rail transports the V-shaped steel sections. As the V-shaped steel passes a baffle, a lifting platform, via a mounting plate, moves multiple spray heads up and down to paint the sections. After painting, any unpainted paint settles under its own weight and is absorbed through the negative pressure pipe. An external recovery system then recycles the paint absorbed by the negative pressure pipe, making it more environmentally friendly. This system solves the technical problem of existing painting equipment that cannot recover paint that did not reach the aluminum surface and remained suspended in the air after painting. The conveyor rail system... The guide rail assembly is easy to install, and its load-bearing capacity can be increased according to actual usage, making it suitable for long-distance conveying applications. With four pulleys, the guide rail can be moved by the pulleys when turning. The connecting rods, if all connected to the guide seats, would result in high conveying rail costs. Using a single connecting rod, which is movable to the guide seat, reduces mass production costs. Because the connecting rod is movable to the guide seat, it reduces interference when the guide seat turns. The lightweight connecting rod also reduces the overall weight of the conveying rail.

[0017] Furthermore, through the frame plate arrangement, the spraying device completely sprays the V-shaped steel from top to bottom. After completion, it rotates 120° via a third rack to return to its initial position and is then transported to the next spraying device for uniform spraying again. During this spraying process, the V-shaped steel rotates, resulting in a more uniform coating thickness. The rack-driven gear plate rotation facilitates control of the rotation angle and eliminates the need for a first motor or other drive device to rotate the gear plate. Utilizing the movement of the gear plate to rotate the V-shaped steel is highly effective. The frame plate also restricts the movement of the V-shaped steel, preventing uneven spraying caused by wobbling during painting and maintaining the stability of the V-shaped steel.

[0018] Furthermore, the clamping device is designed such that each clamp is connected by a chain passing through the ring, the top of each V-shaped steel is connected by a support plate, and the bottom of each V-shaped steel is fixed by the clamps connected by the chains. This design can limit the violent rotation and shaking of each V-shaped steel during the air-drying process, thus preventing collisions and scratches. At the same time, the V-shaped steel has a certain weight, which can also limit the swaying of each row of V-shaped steel due to wind.

[0019] Furthermore, regarding the conveyor belt setup, when clamping V-shaped steel, each clamp is first placed on the support member on the conveyor belt. The conveyor belt then moves the support member to the top, avoiding the laborious problem of manually lifting it to the bottom of the V-shaped steel. Preferably, the conveyor guide rail above the support member is in a "U"-shaped descending and ascending state, and the front-to-back spacing of the support member is the distance the V-shaped steel passes through. When the conveyor belt quickly moves the support member to the top, the V-shaped steel slides down the conveyor guide rail to the top of the clamp. Then, when the conveyor belt moves the support member to the top, the V-shaped steel will be locked between the clamp and the locking block. After clamping, it is lifted by the conveyor guide rail and moved through the front-to-back spacing of the support member. This avoids the disadvantage of needing one person to lift the clamp and place it at the bottom of the V-shaped steel, and then another person to tighten the knob head. The clamping speed can also be increased.

[0020] The positioning column is designed so that when the clamp is placed on the positioning column, the clamp can be limited by the positioning column, avoiding the disadvantage that the clamp is easy to fall off the support when it moves upward. After clamping, when the V-shaped steel is lifted, it directly drives the clamp to detach from the support, without interfering with the lifting of the V-shaped steel.

[0021] The engagement device is designed so that when the conveyor belt moves the support to the top, the V-shaped steel will be locked between the clamping block and the locking block. The moving shaft seat will allow the rotating shaft to slide on the slide rail via the moving block. The rotating shaft will be guided through the engagement seat by the sliding block and locked into the knob head. Then, the rotating device drives the rotating shaft to rotate, which in turn drives the knob head to rotate. The screw drives the locking block to move, so that the clamping block and the locking block lock the V-shaped steel, avoiding the disadvantage of manual screw rotation which is laborious.

[0022] The circular block is designed so that when the conveyor belt quickly moves the support to the top, the second motor will rotate the circular block 90 degrees, maximizing the distance between the contact block and the engagement seat. This will cause the rotating shaft to move to the right via the inner and outer rods, avoiding the rising clamp and allowing it to rise to the top of the conveyor frame. As the conveyor belt moves the support to the top, the V-shaped steel will engage between the clamp and the locking block, causing the circular block to rotate 45 degrees. The distance between the contact block and the engagement seat will then be appropriate. Under the action of the spring, the rotating shaft will press against the knob head. The first motor will drive the drive gear to rotate, which in turn drives the driven gear, thus rotating the rotating shaft. During rotation, the Y-shaped head of the rotating shaft will engage with the Y-shaped head of the knob head. Inside the hole, the rotating shaft is displaced, and the shaft seat moves to the left. During the leftward movement of the shaft seat, the top blocking block obstructs the sensor. After completion, the circular block will continue to rotate 45 degrees, and the blocking block and the engagement seat will be closer together. The first motor will drive the drive gear to rotate at high speed. The drive gear drives the external gear to rotate, and the external gear rotates rapidly, driving the screw to rotate. The screw drives the clamping block to move, so that the clamping block and the locking block clamp the V-shaped steel. After completion, the circular block rotates 90 degrees in the opposite direction, and the distance between the mating block and the engagement seat is maximized, allowing the clamping seat to move through the V-shaped steel. At the same time, it avoids the bottom clamping seat from rising. There is no need to manually move the engagement device to tighten the knob head, which improves the clamping speed and makes it simple and quick to use. Attached Figure Description

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0041] refer to Figures 1 to 16This embodiment provides a V-shaped powder coating booth device for producing aluminum alloy profiles, including a conveying guide rail 1 for conveying V-shaped steel, a painting device 2 for painting V-shaped steel, a baffle 3 spaced apart from the painting device, a negative pressure pipe 4 located at the bottom of the baffle for recycling paint, and a drying device 5 for heating and drying the painted V-shaped steel. The device has V-shaped steel.

[0042] The painting device includes a mounting plate 21 spaced apart from the baffle, a lifting platform 22 for raising and lowering the mounting plate, and multiple paint spray heads 23 located on one end of the mounting plate near the baffle. The negative pressure pipe is connected to the bottom of the baffle. The aforementioned air spray heads, lifting platform, and drying device are all existing conventional technologies and will not be described in detail here. Through the setting of the painting device, the V-shaped steel is transported by the conveying guide rail. When the V-shaped steel passes the baffle during the transport process, the lifting platform drives the mounting plate to move the multiple paint spray heads up and down to paint the V-shaped steel. After completion, some paint is not sprayed on the V-shaped steel. Under the influence of its own weight, the paint sinks and is absorbed through the negative pressure pipe. The paint adsorbed by the negative pressure pipe is recovered by an external recovery system, which is more environmentally friendly. The painted V-shaped steel is then dried and cured by the drying device.

[0043] The conveying guide rail includes four spaced guide rail frames 101, multiple guide seats 102 located in the middle of the guide rail frames and spaced back and forth, first pulleys 103 located at the four corners of the guide seats, second pulleys 104 located at both ends of the guide seats in the lateral direction, protrusions 105 fixed at both ends of the guide seats in the lateral direction, connecting rods 106 rotatably connected to the protrusions on the two guide seats respectively, a first connecting mechanism 107 detachably located at the bottom of the guide seats, a second connecting mechanism 108 detachably located at the bottom of the connecting rod, a rotating rod 109 rotatably located at the bottom of the first and second connecting mechanisms, a gear plate 110 located at the bottom of the rotating rod, and a support plate 111 located at the bottom of the gear plate. The first pulleys are in contact with the longitudinally spaced guide rail frames, the second pulleys are located at the top and bottom of the guide seats respectively, and the second pulleys are in contact with the spaced guide rail frames in the lateral direction. The bottom outer diameter of the protrusion is larger than the top outer diameter of the protrusion. The second pulley is located at the top of the protrusion, and the connecting rod is located at the bottom of the protrusion.

[0044] The conveyor rail setup involves first placing the guide seats inside the rail frame. Then, first pulleys are installed on the front and rear end faces of the guide seats. Next, the top protrusions of two spaced-apart guide seats are inserted into the connecting rod. Finally, second pulleys are installed on the top and bottom protrusions. After the entire conveyor rail is laid, one of the guide seats is connected to an external power assembly. The external power assembly will drive one of the guide seats to move. The bottom of the support plate is connected to the V-shaped steel via hooks, or other existing clamping mechanisms. Since the guide seats are connected by connecting rods, moving the entire set of guide seats and guide rods causes the first pulleys on the guide seats to move in contact with the upper and lower rail frames, and the second pulleys to guide the movement of the front and rear rail frames. This rail frame assembly is convenient for... The structure is easy to install, and its load-bearing capacity can be increased by modifying components according to actual usage, making it suitable for long-distance conveying applications. With four pulleys, the guide rail frame can be moved by the pulleys when turning. The connecting rods, instead of all being connected through the guide seats, would result in high conveyor rail costs. A single connecting rod, which is movable to the guide seat, reduces mass production costs. Because the connecting rod is movable to the guide seat, it reduces interference when the guide seat turns. The lightweight connecting rod also reduces the overall weight of the conveyor rail. The frame plate also restricts the movement of the V-shaped steel, preventing uneven painting caused by V-shaped steel swaying during spraying and maintaining V-shaped steel stability. External power components can be used as... Figure 16 As shown, the external power assembly includes a rotating block 10a spaced apart from the guide rail frame, a power motor 10b for driving the rotating block to rotate, and a clamping block 10c for clamping and moving the tops of each protrusion. The clamping block includes a left clamping block 10d and a right clamping block 10e. The length of the right clamping block is smaller than that of the left clamping block, and the distance between the left clamping block 10d and the right clamping block 10e is greater than the outer diameter of the top of the protrusion. The tops of the protrusions extend upward. The external power assembly can also be replaced with other existing drive mechanisms to achieve the movement of the guide seat.

[0045] During the rotation of the rotating block, the right clamping block avoids the protruding post, while the left clamping block engages with the protruding post during rotation and drives the protruding post to rotate to the right, thereby moving each guide seat. As the rotating block continues to rotate, the protruding post is engaged between the left clamping block 10d and the right clamping block 10e. The left clamping block 10d and the right clamping block 10e rotate to the right to hold the protruding post and slide it to the right end. The left clamping block 10d and the right clamping block 10e at the top of the rotating block will rotate to the left, which can continuously engage and convey the top of the input protruding post. Compared with a chain or a drive vehicle to drive the entire conveyor rail, this method is lower in cost and more stable in conveying.

[0046] A V-shaped guide plate 112 is provided between the toothed disc and the support plate. Two spaced support rods 113 are provided at the bottom end of the guide rail frame at the baffle. Two spaced frame plates 114 are provided at the bottom end of the support rods. A groove 115 for the toothed disc to pass through is provided in the middle of the two frame plates. At least two racks 116 that mesh with the toothed disc are provided on one of the frame plate grooves.

[0047] If the V-shaped steel does not rotate as it passes through the painting device for top and bottom spraying, it will result in excessively thick paint in some areas, leading to a rough, orange-peel-like surface after drying. To avoid this problem of excessively thick and uneven paint application, a frame plate is designed with guide seats and connecting rods to move the support plates. When the V-shaped steel reaches the painting device, it slides into the groove of the frame plate guided by the support rods. As it passes the rack, the rack drives the gear plate to rotate, which in turn drives the support plates and rotating rods to rotate, thus rotating the V-shaped steel. Preferably, three racks of equal length are provided, each rotating the V-shaped steel by 120 degrees. Before passing the first rack, the painting device sprays the inner V-shaped surface of the V-shaped steel from top to bottom. After completion, it passes through... As the V-shaped steel passes through one rack, it rotates 120 degrees. After this rotation, one V-face of the V-shaped steel faces the painting device, which then sprays the steel from bottom to top. Once finished, the V-shaped steel passes through a second rack and rotates 120 degrees again, with the other V-face facing the painting device. The painting device then sprays the V-shaped steel completely from top to bottom. After this, it rotates 120 degrees through a third rack to return to its initial position and is then transported to the next painting device for another uniform spraying. During this spraying process, the V-shaped steel rotates, resulting in a more uniform coating thickness. The rack-driven rotation of the gear disc facilitates control of the rotation angle and eliminates the need for a first motor or other drive devices to rotate the gear disc. Utilizing the movement of the gear disc to rotate the V-shaped steel provides excellent results.

[0048] Preferably, the included angle of the inner side of the V-shaped steel is 90 degrees. The rack includes a first rack 11a for rotating the V-shaped steel by 135 degrees, a second rack 11b for rotating the V-shaped steel by 90 degrees, and a third rack 11c for rotating the V-shaped steel by 135 degrees. Two guide plates 114a with a certain included angle are provided at the frame plate entrance. The guide plates can guide the rack disc into the space between the two frame plates. When the V-shaped steel is at 90 degrees and has not passed the first rack, the inner V-shaped surface a of the V-shaped steel will face the spray nozzle of the painting device. The painting device sprays twice from top to bottom and then from bottom to top onto the inner V-shaped surface a of the V-shaped steel. The inner groove of the inner V-shaped surface a allows for more uniform and better results with two consecutive sprays. Compared to the outer V-shaped surface b, which has a certain slope, the outer V-shaped surface diverts the paint to both sides laterally, requiring more spraying... Multiple coats are required for complete painting, and the edge coating effect is unsatisfactory and uneven after spraying. When it is necessary to spray the outer V-shaped surface, the outer V-shaped surface is divided into two sprayings. After the first rotation of 135 degrees, one of the outer V-shaped surfaces will be parallel to the spraying device. During the second rotation, rotate 90 degrees, and the other outer V-shaped surface will remain parallel to the spraying device. The outer V-shaped surface after the two rotations is parallel to the spraying device. The V-shaped surface parallel to the spraying device has a better edge coating effect and more uniform paint. At the same time, it reduces the number of times the spraying device sprays up and down, resulting in fewer sprayings on the V-shaped steel and a faster spraying speed. Preferably, the included angle between the locking blocks 62 is 90 degrees, and there is a notch between the locking blocks 62 to facilitate the V-shaped steel to be inserted into the locking blocks and fit tightly with the locking blocks. The notch between the locking blocks also facilitates the exposure of the outer surface of the V-shaped steel.

[0049] The damping of the rotating rod with the first and second connecting mechanisms is 2 to 15 n. The rotating rod can be connected to the first and second connecting mechanisms through a damper, which is a conventional technology and will not be described in detail here. When the rotating rod is connected to the first and second connecting mechanisms, if the connection between the rotating rod and the first and second connecting mechanisms is smooth and without resistance, the rotating rod will deviate at a certain angle during the sliding process of the conveying guide rail. When passing through the painting device, this will result in a uniform painted surface. With a certain damping, unless interfered by external forces, the rotating rod will not rotate during the conveying process of the conveying guide rail, which can make the V-shaped steel below the rotating rod enter the painting device at the same angle.

[0050] The drying device has an inlet, and the inlet is provided with multiple clamping devices 6 for clamping each V-shaped steel. The inlet is also provided with a lifting device 7 for lifting the clamping devices. The clamping device includes a clamping seat 61 on the lifting device, a locking block 62 on the clamping seat, a fixing block 63 on the clamping seat away from the locking block, a screw 64 threadedly connected to the fixing block, a clamping block 65 on the screw near the locking block, and a knob head 66 on the screw away from the fixing block. One of the outer surfaces of the clamping seat is provided with a ring portion 6a, and the ring portions on each clamping seat are connected by a chain.

[0051] With the clamping device in place, the lifting device will lift the clamping seat to the bottom of the V-shaped steel. After that, the V-shaped steel will be inserted between the clamping block and the fixing block. Then the screw will be tightened and will move towards the clamping block. At the same time, the screw will move the clamping block towards one end of the clamping block. After that, the fixing block and the clamping block will tightly clamp the bottom of the V-shaped steel. Since each clamping seat is connected by a chain passing through the ring, and the top of each V-shaped steel is connected by a support plate, and the bottom of each V-shaped steel is fixed by the clamping seats connected by the chains, the violent rotation and shaking of each V-shaped steel during the air drying process can be limited, which would lead to collision and scratching. At the same time, the V-shaped steel has a certain weight, which can also limit the swaying of each row of V-shaped steel due to wind.

[0052] The lifting device includes a vertically rotating conveyor belt 71, a conveyor frame 72 for supporting the conveyor belt, and multiple support members 73 disposed on the conveyor belt. The support members are provided in multiples and are spaced apart from each other.

[0053] When clamping V-shaped steel, the conveyor belt is set up so that each clamp is first placed on the support on the conveyor belt. The support is then moved to the top by the conveyor belt, avoiding the laborious problem of manually lifting the support to the bottom of the V-shaped steel. Preferably, the conveyor guide rail above the support is in a "U" shape, descending and ascending. The distance between the front and rear of the support is the distance the V-shaped steel passes through. When the conveyor belt quickly moves the support to the top, the V-shaped steel slides down the conveyor guide rail to the top of the clamp. Then, when the conveyor belt moves the support to the top, the V-shaped steel will be locked between the clamp and the clamping block. After clamping, it is lifted by the conveyor guide rail and moved through the spaced support to the bottom. This avoids the disadvantage of needing one person to lift the clamp and place it at the bottom of the V-shaped steel, and then another person to tighten the knob. The clamping speed can also be increased.

[0054] The clamp is provided with a positioning hole 67, and the support is provided with a positioning post 74 passing through the positioning hole. When the clamp is placed on the positioning post, the positioning post can limit the clamp, avoiding the disadvantage that the clamp is easy to fall off the support when it moves upward. After clamping, when the V-shaped steel is lifted, it directly drives the clamp block to detach from the support, without interfering with the lifting of the V-shaped steel.

[0055] The top of the conveyor frame is provided with a screw-on device 8 for rotating the knob head. The screw-on device includes a screw-on seat 801, a slide rail 802 provided on the bottom end face of the screw-on seat, a moving block 803 slidably provided on the slide rail, a shaft seat 804 provided on the top of the moving block, a rotating shaft 805 rotatably provided in the shaft seat, a sliding block 806 slidably provided at the end of the rotating shaft away from the shaft seat, a Y-shaped head 807 provided at the end of the rotating shaft away from the shaft seat, and a rotating device 808 for driving the rotating shaft to rotate. The Y-shaped head passes through the screw-on seat, and the sliding block is connected to the screw-on seat.

[0056] With the setting of the engagement device, when the conveyor belt moves the support to the top, the V-shaped steel will be locked between the clamping block and the clamping block. The moving shaft seat will allow the rotating shaft to slide on the slide rail via the moving block. The rotating shaft will be guided through the engagement seat by the sliding block and locked into the knob head. Then the rotating device drives the rotating shaft to rotate, which in turn drives the knob head to rotate. The screw drives the clamping block to move, so that the clamping block and the clamping block lock the V-shaped steel, avoiding the disadvantage of the laboriousness of manually rotating the screw.

[0057] The knob head is provided with a Y-shaped hole x that is inserted into the Y-shaped head, making it easy for the Y-shaped head to be inserted into the Y-shaped hole.

[0058] An external gear 809 is provided on the outer side of the rotating shaft. The rotating device includes a first motor 810 connected to the engagement seat. The output shaft of the first motor has a driving gear 811 that meshes with the external gear. The width of the driving gear is smaller than the width of the external gear. A spring 812 is provided at the end of the rotating shaft away from the Y-head, and the spring is located between the rotating shaft and the engagement seat. An outer rod 813 is provided at the end of the rotating shaft away from the Y-head, and an inner rod 814 is provided at the end of the rotating shaft near the Y-head, which is rotatably connected to the outer rod. The outer rod and the inner rod pass through the engagement seat.

[0059] The inner rod is provided with a fitting block 815 at the end away from the outer rod. The screw seat is provided with an extension seat 816 near the fitting block. An elliptical block 817 is rotatably provided on the extension seat. A second motor 818 for driving the block to rotate is provided on the extension seat. A blocking block 819 is provided at the top of the shaft seat. A sensor 820 for sensing the movement of the Y-shaped head of the rotating shaft into the Y-shaped hole is provided on the screw seat. Specifically, when the Y-shaped head of the rotating shaft moves into the Y-shaped hole, it will cause the blocking block on the rotating shaft to move and block the sensor. Preferably, there are three sensors. The middle sensor is used to detect the movement of the Y-shaped head of the rotating shaft into the Y-shaped hole. The left sensor is used to detect the clamping block and the locking block clamping the V-shaped steel. The right sensor detects the movement of the rotating shaft to the right end.

[0060] When the conveyor belt quickly moves the support to the top, the second motor will rotate the round block 90 degrees, maximizing the distance between the contact block and the engagement seat. This will cause the rotating shaft to move to the right via the inner and outer rods, avoiding the rising clamp and allowing it to rise to the top of the conveyor frame. As the conveyor belt moves the support to the top, the V-shaped steel will engage between the clamp and the locking block, causing the round block to rotate 45 degrees. The distance between the contact block and the engagement seat will then be appropriate. Under the action of the spring, the rotating shaft will press against the knob head. The first motor will drive the drive gear to rotate, which in turn drives the driven gear, thus rotating the rotating shaft. During rotation, the Y-shaped head of the rotating shaft will engage with the Y-shaped hole in the knob head. The rotating shaft generates displacement, and the shaft seat moves to the left. During the leftward movement of the shaft seat, the top blocking block obstructs the sensor. After completion, the circular block will continue to rotate 45 degrees, and the distance between the blocking block and the engagement seat will approach. The first motor will drive the drive gear to rotate at high speed, which in turn drives the external gear to rotate. The rapid rotation of the external gear drives the screw to rotate, and the screw drives the clamping block to move, so that the clamping block and the locking block clamp the V-shaped steel. After completion, the circular block rotates 90 degrees in the opposite direction, and the distance between the mating block and the engagement seat is maximized, allowing the clamping seat to move through the V-shaped steel while avoiding the bottom clamping seat from rising. There is no need for manual movement of the engagement device to tighten the knob head, which improves the clamping speed and makes it simple and quick to use.

[0061] The specific principle is as follows: First, each clamp is placed on the support on the conveyor belt. When the clamp is placed on the positioning post, the clamp can be limited by the positioning post. When the conveyor belt quickly moves the support to the top, the second motor will drive the round block to rotate 90 degrees. The distance between the fitting block and the rotating seat is at its maximum. The inner and outer rods will drive the rotating shaft to move to the right to avoid the rising clamp and allow it to rise to the top of the conveyor frame. At the same time, when the conveyor belt quickly moves the support to the top, the V-shaped steel slides down to the top of the clamp through the conveyor guide rail. Then, when the conveyor belt moves the support to the top, the V-shaped steel will be inserted between the clamp and the clamping block. The round block will rotate 45 degrees. The distance between the fitting block and the rotating seat is moderate. The rotating shaft will press against the knob head under the action of the spring. The first motor drives the drive gear to rotate. The driven gear drives the driven gear to rotate, which in turn drives the rotating shaft to rotate. During the rotation, the Y-shaped head of the rotating shaft will engage with the Y-shaped hole of the knob head, causing the rotating shaft to shift. The shaft seat moves to the left, and during the leftward movement of the shaft seat, the top blocking block obstructs the sensor. After completion, the circular block will continue to rotate 45 degrees, and the distance between the blocking block and the engagement seat will be closer. The first motor will drive the driving gear to rotate at high speed, which in turn drives the external gear to rotate. The rapid rotation of the external gear drives the screw to rotate, and the screw drives the clamping block to move, so that the clamping block and the locking block clamp the V-shaped steel. After completion, the circular block rotates 90 degrees in the opposite direction, and the distance between the mating block and the engagement seat is maximized, allowing the clamping block to move through the V-shaped steel. After clamping, the clamping block is lifted by the conveyor guide rail and moves through the front and rear spaced support members, while avoiding the bottom clamping block from rising.
