Description

Technical Field

[0001] The invention relates to the technical field of profile spraying, and in particular to a vertical spraying production line for the surface of an aluminum alloy profile. Background Art

[0002] Existing profile spraying lines can be divided into vertical (vertical) lines and horizontal (horizontal) lines according to the structure of the production line and the way the products are suspended. The vertical line mainly uses hooks to vertically suspend the profiles with holes at the ends, and various process treatments are carried out along the conveyor chain. According to the characteristics of profile suspension, the pre-spraying treatment process of the vertical line usually adopts the spraying treatment method, and after the treatment, it can directly carry out drying, spraying and other operations.

[0003] Patent CN114570560A discloses a profile dislocation device for a vertical spraying line, including a guide assembly, a swing assembly and a partition assembly, the pre-processing station is provided with a conveyor chain, the conveyor chain is hung with profiles, the guide assembly includes an inlet and a running channel arranged behind the inlet, the swing assembly includes a swing block and a rotating shaft, the swing block can swing back and forth around the rotating shaft, the swing block is provided with a first guide side and a second guide side arranged oppositely, the partition assembly includes a partition, the swing block can guide the adjacent profiles that hit the swing block to the opposite sides of the partition in sequence through the first guide side and the second guide side respectively when swinging back and forth. This patent can automatically separate the profiles from each other, effectively avoid collisions, sticking and other problems caused by the shaking of the tail of the profile, save manpower and material costs, and improve the quality of spraying.

[0004] When the profile dislocation device for the vertical spraying line in the above-mentioned patent is in use, in order to avoid problems such as collision and sticking caused by the shaking of the tail of the profile during spraying, a swing block is used to stagger the two adjacent profiles, and then the two staggered profiles are separated to both sides by a partition, so that the profile remains separated during operation. However, this causes the partition to block the profile during spraying, resulting in imperfect spraying of the profile. At the same time, since the partition will contact the surface of the profile during separation, it will inevitably cause friction and scratches of the paint near the contact surface, further reducing the spraying quality. In addition, the profile is hindered by the partition, making it difficult to implement rotational spraying. For the spraying of profiles of different shapes other than flat, the spraying effect will also be reduced. Therefore, it is not suitable for the spraying of profiles of different shapes.

[0031] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] Embodiment 1

[0033] like Figure 1-Figure 8As shown, a vertical spraying production line for the surface of aluminum alloy profiles comprises a horizontal conveying track 1, an inverted trapezoidal bar 11 is arranged on the upper wall of the inner cavity of the horizontal conveying track 1, tooth plates 13 are fixedly connected to the front and rear sides of the lower wall of the horizontal conveying track 1, a plurality of conveying blocks 2 movably connected head to tail for conveying profiles are arranged in the horizontal conveying track 1, a swing plate 21 is rotatably connected to the middle part of the conveying block 2, a card slot 22 is provided at the right end of the swing plate 21, an elastic card column 7 capable of docking with the card slot 22 is slidably connected to the cavity wall of the conveying block 2, a rotating tube 23 is rotatably connected to the bottom of the swing plate 21, an elastic top column 41 movably penetrating from the top of the swing plate 21 is arranged on the top of the inner cavity of the rotating tube 23, the elastic top column 41 can drive the rotating tube 23 to rotate, and the elastic top column 41 can be abutted and retracted with the inverted trapezoidal bar 11;

[0034] A mounting frame 25 is fixedly connected to the bottom of the rotating tube 23, and limit blocks 26 are fixedly connected to the left and right sides of the bottom of the mounting frame 25. Mounting plugs 3 are slidably inserted on the left and right sides of the mounting frame 25. A hook-shaped gear rod 3 is rotatably connected to the mounting plug 3. A fixed component for squeezing the top of the profile is provided at the bottom of the hook-shaped gear rod 33, and the hook-shaped gear rod 33 can be meshed and connected with the tooth plate 13.

[0035] During spraying production, the left end of the horizontal conveying track 1 can be connected to the input slope track, and the right end of the horizontal conveying track 1 can be connected to the output slope track, so as to control the low-position mounting and collection of the profiles. The horizontal conveying track 1 can be passed into the spraying room or other corresponding combinations of spraying and drying rooms as needed. When passing into the spraying room, the profiles mounted on the hook-shaped toothed rod 33 are conveyed by the conveying block 2. During conveying, the elastic clamping column 7 automatically docks with the clamping groove 22 at the right end of the swing plate 21, thereby limiting the swing plate 21 to prevent it from subsequently driving the profiles to spray. When the elastic top column 41 passes the left end of the inverted trapezoidal bar 11, the elastic top column 41 is passively squeezed by the inverted trapezoidal bar 11, and the rotating tube 23 can timely and automatically drive the mounting frame 25 to deflect, and automatically control the mounting plugs 3 on both sides to extend, so as to drive the two hook-shaped gear rods 33 to move away from each other, and the profiles originally transported in a single row are transported in a double row, and the mounting distance between the profiles is automatically increased, thereby effectively reducing the probability of collision between the profiles during spraying and improving the spraying quality. After the two hook-shaped gear rods 33 move away from each other, the hook The hook-shaped toothed rod 33 automatically meshes with the toothed plate 13. As the conveying block 2 continues to operate, the hook-shaped toothed rod 33 automatically meshes with the toothed plate 13 and rotates to implement dynamic spraying of the profile, which is suitable for spraying of profiles of different shapes. The spraying is not blocked or scratched, and the spraying effect is good. When the two hook-shaped toothed rods 33 move away from each other, the fixed component is driven outward with the hook-shaped toothed rod 33. The fixed component is automatically squeezed on the top of the profile by the extrusion of the limited position block 26, thereby limiting the profile and avoiding shaking when the profile is mounted. Since the swing plate 21 is limited When the conveying block 2 leaves the obstruction area of ​​the inverted trapezoidal bar 11, the swing plate 21 can swing clockwise and counterclockwise, so that the conveying block 2 and the mounting part below it can be automatically adjusted to be vertical for optimal force during rail transportation on the output slope.

[0036] Embodiment 2, based on the above embodiment, provides a driving mechanism for the elastic clamping column 7:

[0037] like Figure 4-Figure 5 As shown, a hollow T-shaped swing rod 71 is rotatably connected to the bottom of the cavity wall of the conveying block 2, and a hinge rod 72 is movably connected between the T-shaped swing rod 71 and the elastic clamping column 7;

[0038] A slot is provided at the bottom of the horizontal conveying track 1 , the slot width is greater than the outer diameter of the rotating tube 23 , and blocking bars 12 are provided on both the front and rear sides of the slot, which can squeeze the two ends of the bottom of the T-shaped swing rod 71 .

[0039] When the conveying block 2 drives the T-shaped rocker arm 71 to pass the left end of the baffle bar 12, the baffle bar 12 passively squeezes the T-shaped rocker arm 71 to deflect until the T-shaped rocker arm 71 deflects to the upper end of the baffle bar 12, and the corresponding T-shaped rocker arm 71 drives the hinge rod 72 to push the elastic clamping column 7 to move left and dock with the clamping slot 22, thereby limiting the swing plate 21 to prevent it from swinging during the subsequent driving of the profile spraying. Since the swing plate 21 can drive the corresponding hook-shaped tooth rod 33 to be vertical when limited, the fixed component squeezes the top of the profile so that the mounted profile is also vertical. The profile has a smaller force on its mounting part, and the profile mounting and spraying is stable, which further reduces the probability of collision between profiles during spraying and improves the spraying quality.

[0040] Furthermore, the left end of the elastic clamping column 7 is conical, and the edge of the right port of the clamping slot 22 is rounded.

[0041] When the conveying block 2 enters the horizontal conveying track 1 from the external input slope track, and when the swing plate 21 is accidentally stuck and fails to drive the corresponding mounting part to be completely vertical, the slot 22 is inclined relative to the elastic clamping column 7, but the tapered part at the left end of the elastic clamping column 7 and the rounded corners of the edge of the right port of the slot 22 cooperate with each other, and the elastic clamping column 7 can still be inserted and clamped into the slot 22, stably driving the swing plate 21 and its corresponding mounting part to be vertical, avoiding collisions caused by crooked profile mounting during spraying.

[0042] Embodiment 3, based on the above embodiment:

[0043] like Figure 3 As shown, the length of the blocking bar 12 is equal to the length of the toothed plate 13 , and two ends of the blocking bar 12 extend beyond two ends of the inverted trapezoidal bar 11 .

[0044] By designing that the two ends of the blocking bar 12 exceed the two ends of the inverted trapezoidal bar 11, before the inverted trapezoidal bar 11 is used to passively extrude the elastic top column 41 to control the automatic increase of the mounting distance between the profiles, the elastic clamping column 7 can be controlled to move leftward and dock with the clamping slot 22, and the swing plate 21 is first limited to prevent it from swinging, so that the elastic top column 41 can subsequently be in stable contact with the inverted trapezoidal bar 11 in a vertical state, and the mounting distance between the control profiles can be automatically increased in time. Correspondingly, before the elastic top column 41 is separated from the inverted trapezoidal bar 11, the elastic clamping column 7 is still docked with the clamping slot 22 to control the limitation of the swing plate 21, thereby ensuring that the mounting distance between the profiles can be stably maintained after the increase. In addition, since the two ends of the tooth plate 13 also exceed the two ends of the inverted trapezoidal bar 11, after the mounting distance between the profiles is automatically increased, it can ensure that the hook-type tooth rod 33 can also be timely Mesh with the tooth plate 13 for rotary spraying.

[0045] Embodiment 4, based on the above embodiment, provides a driving mechanism for the rotating tube 23:

[0046] like Figure 4 and Figure 6 As shown, a fixed cylinder 4 is fixedly connected to the bottom of the swing plate 21, and the fixed cylinder 4 is rotatably connected to the inner wall of the rotating tube 23. An elastic top column 41 is movably connected in the fixed cylinder 4. Two circumferentially distributed arc grooves 24 are provided on the inner wall of the rotating tube 23. Pins 42 movably engaged with the corresponding arc grooves 24 are provided on the left and right sides of the elastic top column 41, and sliding grooves adapted to the pins 42 are provided on the left and right sides of the fixed cylinder 4.

[0047] When the elastic top column 41 is squeezed and contracted by the inverted trapezoidal bar 11 and moves downward, the elastic top column 41 drives the pins 42 on both sides to move vertically downward along the slide groove, and the pins 42 squeeze and move the corresponding arc groove 24, thereby driving the rotating tube 23 to deflect the mounting frame 25, so that the subsequent mounting plug block 3 drives the hook-shaped gear rod 33 to allow the profile to have sufficient extension space.

[0048] Furthermore, the top of the elastic top column 41 is designed to be conical and is rotatably connected to a group of rollers 43 .

[0049] By the roller 43 contacting the surface of the inverted trapezoidal bar 11 , the transmission is smoother and more stable than direct contact with the elastic top column 41 . Combined with the conical design of the top of the elastic top column 41 , it helps to reduce the volume of the top of the elastic top column 41 and avoid direct contact with the inverted trapezoidal bar 11 .

[0050] Embodiment 5, based on the above embodiment, provides a driving mechanism for mounting plug block 3:

[0051] like Figure 4 and Figure 7 As shown, a fixed bevel gear rod 5 is rotatably inserted in the middle of the mounting frame 25, and the fixed bevel gear rod 5 is fixedly connected to the lower wall of the fixed cylinder 4. The left and right sides of the inner cavity of the mounting frame 25 are rotatably connected to bevel gear cylinders 51 meshing with the fixed bevel gear rod 5, and the inner wall of the bevel gear cylinder 51 is provided with a curved groove 52;

[0052] A guide rod 31 movably plugged into the bevel gear cylinder 51 is fixedly connected to the inner wall of the mounting plug block 3 , and a pin protrusion 32 movably engaged with the curved groove 52 is provided on the lower wall of the guide rod 31 .

[0053] When the mounting frame 25 is driven to deflect by the rotating tube 23, the bevel gear cylinder 51 engages with the fixed bevel gear rod 5 and is passively deflected, thereby driving the curved groove 52 to deflect. The curved groove 52 squeezes the pin protrusion 32 movably engaged with it, thereby driving the mounting block 3 to move outward. The mounting block 3 drives the hook gear rod 33 to move the mounted profile outward, and the mounting distance between the two profiles on the same mounting frame 25 increases.

[0054] Embodiment 6, based on the above embodiment, provides a fixing component structure:

[0055] like Figure 4 and Figure 8 As shown, the fixing assembly includes a fixing tube 6 which is slidably engaged on the hook-shaped tooth rod 33, an H-shaped fixing plate 61 is arranged at the bottom of the fixing tube 6, a plurality of wedge grooves 62 are linearly opened on the rear wall of the hook-shaped tooth rod 33 along the length direction, an elastic wedge block 63 which can be engaged with the wedge groove 62 is slidably engaged on the rear wall of the inner cavity of the fixing tube 6, a pressure frame 64 is fixedly connected to the rear end of the elastic wedge block 63, and the pressure frame 64 is slidably engaged on the outer wall of the fixing tube 6.

[0056] Furthermore, the bottom of the limit block 26 is in an inverted trapezoidal shape and movably abuts against the top of the fixed tube 6 . The outer edge of the top of the fixed tube 6 is rounded, and a movable groove corresponding to the hook-shaped tooth rod 33 is opened in the middle of the limit block 26 .

[0057] When the two hook-shaped toothed rods 33 on the same mounting frame 25 move away from each other, the fixing tube 6 on the hook-shaped toothed rod 33 is squeezed by the inverted trapezoidal part at the bottom of the limited block 26, and the fixing tube 6 thereby continuously drives the elastic wedge block 63 to be compressed and moved downward and is clamped into the next wedge groove 62. When the fixing tube 6 smoothly moves to the lowermost end of the limit block 26 by utilizing the rounded corner design of the top outer edge of the fixing tube 6, the fixing tube 6 drives the H-shaped fixing plate 61 to squeeze and fix the top end of the profile, and the elastic wedge block 63 and the wedge groove 62 are just clamped to prevent the H-shaped fixing plate 61 from moving up and being released from the fixation. Subsequently, when the hook-shaped toothed rod 33 is reset, the H-shaped fixing plate 61 is still stably abutted against the top end of the profile by the clamping restriction of the elastic wedge block 63 and the wedge groove 62, and the fixation is firm and reliable. When the profile is subsequently collected, the elastic wedge block 63 is driven to disengage from the wedge groove 62 by pressing the pressing frame 64 and controlling the fixing tube 6 to move up, so that the fixing tube 6 can be controlled to drive the H-shaped fixing plate 61 to reset, and the collection is convenient and quick.
