Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate spray painting, and in particular to a surface spraying device for an imitation marble aluminum single plate. Background Art

[0002] Aluminum veneer refers to a building decoration material that is processed by chromization and other treatments and then processed by fluorocarbon spraying technology. Among them, imitation marble aluminum veneer is to spray real stone paint on the decorative surface of the aluminum veneer to achieve the visual effect of marble slab decoration, which improves the decorative effect and reduces the decoration cost. The commonly used real stone paint is water-in-water spray paint. During the spraying process, the aluminum veneer needs to be transported by a hanger, and then the surface of the aluminum veneer is sprayed with a spray gun.

[0003] For example, in the patent document entitled "A hanging device for aluminum veneer painting" with the authorization announcement number CN216573743U, the hanging block is connected to the hanging chain through two upper hooks. According to the structure of the product to be hung, the position of the adjustment mechanism is adjusted, and then the position of the adjustment hook is adjusted. Then the product is hung on the adjustment hook and the lower hook to improve the stability of the hanging. The adjustment hook and the lower hook can be replaced with different lengths at any time to meet the use requirements.

[0004] For the above related technologies, refer to Figure 1 , decorative surface two is facing people's sight as a decorative surface, and at the edge of the decoration, decorative surface one and decorative surface three are also seen as decorative surfaces and need to be painted. Decorative surface one and decorative surface three are both perpendicular to decorative surface two. The aluminum veneer is hung on a hook. When the spray gun is spraying decorative surface two, decorative surface one and decorative surface three are parallel to the spray gun. The moving trajectory of the real stone paint is parallel to decorative surface one and decorative surface three. The decorative surface parallel to the spray gun is difficult to fully contact with the real stone paint, resulting in different painting effects on different decorative surfaces of the aluminum veneer, which reduces the overall appearance of the aluminum veneer. Summary of the invention

[0005] In view of this, the present invention provides a marble-like aluminum veneer surface spraying device, which aims to solve the problem that the decorative surface parallel to the spray gun is difficult to fully contact with the real stone paint, thereby causing different spraying effects on different decorative surfaces of the aluminum veneer.

[0006] In order to solve the above technical problems, the present invention provides a marble-like aluminum veneer surface spraying device, comprising a bracket, a hanger and a transport mechanism for driving the hanger to move, the aluminum veneer comprising a decorative surface 1, a decorative surface 2 and a decorative surface 3; the bracket is horizontally provided with a spray gun 1 arranged opposite to the decorative surface 2, and a spray gun 2 and a spray gun 3 arranged obliquely; the bracket is fixedly connected with a guide rail 1 and a guide rail 2, the guide rail 1 is provided with a guide groove 1 at a position opposite to the spray gun 2, and the guide rail 2 is provided with a guide groove 2 at a position opposite to the spray gun 3; the hanger is fixedly connected with a connecting frame, the hanger is slidably connected with a connecting rod 1 and a connecting rod 2, and the upper end of the connecting rod 1 is rotatably connected with a connecting rod 1 arranged on the guide rail 1. Roller 1 of rail 1, the upper end of connecting rod 2 is rotatably connected with roller 2 set on guide rail 2, connecting rod 1 is provided with transmission mechanism 1, connecting rod 2 is provided with transmission mechanism 2, transmission mechanism 1 includes guide block 1 fixedly connected to one side wall of the connecting rod, a connecting frame is slidably connected with a transmission rod 1 that can abut against the guide block 1, and the connecting frame is hinged with a fastening mechanism for fastening the aluminum single plate. When roller 1 is located in guide groove 1, the fastening mechanism can be pushed and rotated by transmission rod 1 to make the decorative surface 1 perpendicular to spray gun 2; the transmission mechanism 2 has the same structure as the transmission mechanism 1. When roller 2 is located in guide groove 2, decorative surface 3 rotates to be perpendicular to spray gun 3.

[0007] By adopting the above technical solution, the transport mechanism drives the aluminum veneer to move through the hanger, and the aluminum veneer passes through spray gun 1, spray gun 2 and spray gun 3 in sequence. The hanger drives roller 1 to rotate through connecting rod 1, and the hanger drives roller 2 to rotate through connecting rod 2. The aluminum veneer moves synchronously with the hanger to spray gun 1, and spray gun 1 sprays the real stone paint to decorative surface 2. When the transport mechanism transports the aluminum veneer to spray gun 2 through the hanger, roller 1 moves to guide groove 1, roller 1 moves downward, roller 1 drives guide block 1 to move downward through connecting rod 1, and guide slope 2 moves downward to push the support ball and transmission rod 1 to move close to the fastening mechanism, and the support ball reduces the sliding friction between guide slope 2 and transmission rod. Transmission rod 1 pushes the fastening mechanism to rotate around the pin shaft, and the fastening mechanism drives the aluminum veneer to rotate synchronously. The decorative surface 1 rotates synchronously with the aluminum veneer to face spray gun 2 which is tilted downward, so that spray gun 2 sprays real stone paint on decorative surface 1. Similarly, spray gun 3 sprays real stone paint on decorative surface 3.

[0008] While the transport mechanism drives the aluminum veneer to move through the hanger, it uses guide groove one and guide groove two to drive the aluminum veneer to rotate. Guide groove one and guide groove two rotate synchronously with the aluminum veneer. Because spray gun two and spray gun three are arranged at an angle, spray gun two sprays real stone paint on decorative surface one, and spray gun three sprays real stone paint on decorative surface three, which is beneficial to full contact between different decorative surfaces of the aluminum veneer and the real stone paint, thereby improving the painting effect of the aluminum veneer.

[0038] Reference Figure 2 , Figure 3 and Figure 4 The bracket 1 is horizontally fixedly connected with a guide rail 1 5 and a guide rail 2 54. A slide groove 1 51 is provided inside the guide rail 1 5, and a slide groove 2 55 is provided inside the guide rail 2 54. The slide groove 1 51 and the slide groove 2 55 are arranged opposite and parallel to each other, wherein the middle part of the guide rail 1 5 is arranged as a guide groove 1 52, which is arranged opposite to the spray gun 2 42, and the guide groove 1 52 is lower than the slide groove 1 51. One end of the guide rail 2 54 is arranged as a guide groove 2 56, which is arranged opposite to the spray gun 3 43, and the guide groove 2 56 is lower than the slide groove 2 55.

[0039] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The hanger 2 is vertically slidably connected with a connecting rod 1 21 and a connecting rod 2 9, and the upper end of the connecting rod 1 21 is rotatably connected with a roller 1 22, which is rotatably arranged on a guide rail 1 5. The upper end of the connecting rod 2 9 is rotatably connected with a roller 2 91, which is rotatably arranged on a guide rail 2 54. The side walls of the connecting rods 1 21 and 2 9 are fixedly connected with a connecting frame 24, and the end of the connecting frame 24 away from the connecting rod 1 21 is hinged with a fastening mechanism 6 through a pin 29. The fastening mechanism 6 is used to fix the aluminum single plate 8 so that the aluminum single plate 8 moves synchronously with the hanger 2, and a reset torsion spring 28 is fixedly connected between the connecting frame 24 and the fastening mechanism 6.

[0040] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6The connecting frame 24 is horizontally slidably connected with a transmission rod 1 25 and a transmission rod 2 93. The transmission rod 1 25 is arranged opposite to the connecting rod 1 21, and the transmission rod 2 93 is arranged opposite to the connecting rod 2 9. The transmission rod 1 25 is located above the pin 29, and the transmission rod 2 93 is located below the pin 29. The side wall of the connecting rod 1 21 is fixedly connected with a guide block 1 23, and the bottom wall of the guide block 1 23 is provided with a guide slope 2 231. The side wall of the connecting rod 2 9 is fixedly connected with a guide block 3 92, and the bottom wall of the guide block 3 92 is provided with a guide slope 3 921. The transmission rod 1 25 and the transmission rod 2 93 are both rotatably connected with a support ball 252, and the support ball 252 can abut against the guide slope 2 231 and the guide slope 3 921. The outer side surfaces of the transmission rod 1 25 and the transmission rod 2 93 are sleeved with a return spring 251, and the return spring 251 is used to drive the transmission rod 1 25 and the transmission rod 2 93 away from the fastening mechanism 6.

[0041] The transport mechanism 3 drives the aluminum plate 8 to move through the hanger 2, and the aluminum plate 8 passes through the spray gun 1 41, the spray gun 2 42 and the spray gun 3 43 in sequence. The hanger 2 drives the roller 1 22 to rotate through the connecting rod 1 21, and the hanger 2 drives the roller 2 91 to rotate through the connecting rod 2 9. First, the aluminum plate 8 moves synchronously with the hanger 2 to the spray gun 1 41, and the spray gun 1 41 sprays the real stone paint to the decorative surface 2 82. When the transport mechanism 3 transports the aluminum plate 8 to the spray gun 2 42 through the hanger 2, the roller 1 22 moves to the guide groove 1 52, and the roller 1 22 moves downward. The roller 1 22 drives the guide block 1 23 to move downward through the connecting rod 1 21, and the guide slope 2 231 moves downward to push the support ball 252 and the transmission rod 1 25 to move close to the fastening mechanism 6, and the support ball 252 reduces the sliding friction between the guide slope 2 231 and the transmission rod 1 25. The transmission rod 25 pushes the fastening mechanism 6 to rotate counterclockwise around the pin 29 (refer to Figure 5 ), the fastening mechanism 6 drives the aluminum single plate 8 to rotate synchronously, and the decorative surface 81 rotates synchronously with the aluminum single plate 8 to face the spray gun 2 42 which is arranged tilted downward, so that the spray gun 2 42 sprays the real stone paint on the decorative surface 81.

[0042] Similarly, when the hanger 2 moves to the spray gun 3 43, the guide groove 3 pushes the roller 2 91 to move downward. Since the transmission rod 2 93 is located below the pin 29, the roller 2 91 sequentially passes through the connecting rod 2 9, the transmission rod 2 93 and the fastening mechanism 6 to push the aluminum plate 8 to rotate clockwise (refer to Figure 5 ), so that the decorative surface 3 83 faces the spray gun 3 43 which is tilted upward, and the spray gun 3 43 sprays the real stone paint on the decorative surface 3 83. When the roller 1 22 is separated from the guide groove 1 52 and the roller 2 91 is separated from the guide groove 2 56, the reset torsion spring 28 drives the fastening mechanism 6 to rotate to a vertical state.

[0043] While the transport mechanism 3 drives the aluminum veneer 8 to move through the hanger 2, the guide groove 1 52 and the guide groove 2 56 are used to drive the aluminum veneer 8 to rotate. The guide groove 1 52 and the guide groove 2 56 rotate synchronously with the aluminum veneer 8. Because the spray gun 2 42 and the spray gun 3 43 are arranged at an angle, the spray gun 2 42 sprays the real stone paint on the decorative surface 1 81, and the spray gun 3 43 sprays the real stone paint on the decorative surface 3 83, which is beneficial for the different decorative surfaces of the aluminum veneer 8 to fully contact with the real stone paint, thereby improving the painting effect of the aluminum veneer 8.

[0044] Reference Figure 2 and Figure 7 The transport mechanism 3 includes a rotating source 31, a driving wheel 38, a transmission wheel 32, a driven wheel 33, a conveyor belt 39, a friction belt 34 and a friction wheel 35. The rotating source 31 is fixedly connected to the top wall of the bracket 1, the driving wheel 38 is fixedly sleeved on the driving shaft of the rotating source 31, the transmission wheel 32 and the driven wheel 33 are both rotatably connected to the bracket 1, the conveyor belt 39 is sleeved on the outer side of the driving wheel 38 and the transmission wheel 32, and the friction belt 34 is sleeved on the outer side of the transmission wheel 32 and the driven wheel 33. The rotating source 31 drives the friction belt 34 to run through the driving wheel 38, the conveyor belt 39 and the transmission wheel 32 in sequence. There are multiple friction wheels 35, all of which are slidably arranged in the slide groove provided in the bracket 1, the outer side of the friction wheel 35 is in contact with the bottom surface of the friction belt 34, and the friction belt 34 drives the friction wheel 35 to move along the circumferential direction of the guide rail 5 by friction, and a connecting piece is hinged between two adjacent friction wheels 35, and the friction wheel 35 is fixedly connected to the hanger 2.

[0045] Reference Figure 6 , Figure 8 and Fig. 9 The fastening mechanism 6 includes a support plate 26 hinged to the connecting frame 24, a receiving cavity 261 is provided in the support plate 26, a driving rod 61 is horizontally slidably connected to the support plate 26, a tension spring 611 is sleeved on the outer side of the driving rod 61, and the tension spring 611 is used to push the driving rod 61 to move inside the support plate 26. A driving rack 62 is fixedly connected to the outer side of the driving rod 61, a transmission gear 63 that can mesh with the driving rack 62 is rotatably connected in the receiving cavity 261, and a cam 64 is coaxially fixedly connected to the transmission gear 63. There are two sliding plates 65 slidably connected in the accommodating cavity 261. The two sliding plates 65 are arranged on both sides of the transmission gear 63 in the vertical direction. The cam 64 can push the sliding plate 65 to move. The sliding plate 65 is fixedly connected with a fastening block 27. There are four fastening blocks 27 and they are evenly distributed on the upper and lower sides of the support plate 26. The fastening blocks 27 are pressed against the inner side surfaces of the decorative surface 2 82 and the decorative surface 3 83 to fasten the aluminum single plate 8. A return spring 1 66 is connected between the sliding plate 65 and the accommodating cavity 261, and the return spring 1 66 is in a compressed state.

[0046] When installing the aluminum panel 8, the operator pulls the drive rod 61 toward the outside of the support plate 26 to compress the tension spring 611. The drive rod 61 drives the cam 64 to rotate by driving the rack 62 and the transmission gear 63, so that the far resting point of the cam 64 rotates away from the sliding plate 65. The two sliding plates 65 move closer to each other under the action of the reset spring 66, and the fastening block 27 moves synchronously with the sliding plate 65. The operator places the aluminum panel 8 on the fastening block 27.

[0047] The operator releases the drive rod 61, and the compressed tension spring 611 pushes the drive rod 61 to move inside the support plate 26. The drive rod 61 drives the cam 64 to rotate by driving the rack 62 and the transmission gear 63, so that the cam 64 rotates to a vertical state. The cam 64 rotates and pushes the two sliding plates 65 away from each other. The fastening block 27 moves synchronously with the sliding plate 65 to press the inner side of the aluminum single plate 8. The cam 64 and the sliding plate 65 support the fastening block 27 with friction. When the cam 64 presses the sliding plate 65 and the cam 64 is in an inclined state, the tension spring 611 can push the drive rod 61 to move inside the support plate 26, which can increase the extrusion force between the cam 64 and the sliding plate 65, and then increase the friction between the cam 64 and the sliding plate 65. After the aluminum single plate 8 is painted, the operator pulls the drive rod 61 to the outside of the support plate 26, and the fastening block 27 moves synchronously with the sliding plate 65 to disengage from the aluminum single plate 8, thereby removing the aluminum single plate 8.

[0048] In addition, the fastening mechanism 6 can also be a cylinder that drives the fastening block 27 to move in the vertical direction, but the cylinder needs a ventilation pipe to connect to the external air source. Considering that the fastening mechanism 6 needs to drive the aluminum plate 8 to move, the flexibility of the fastening mechanism 6 of the present invention is better than that of the cylinder.

[0049] Reference Figure 3 and Figure 4 Both guide rail 1 5 and guide rail 2 54 are provided with adjustment grooves 53 , and the adjustment grooves 53 of guide rail 1 5 and guide rail 2 54 are arranged opposite to each other, and the adjustment grooves 53 are located on the side of spray gun 1 41 away from spray gun 2 42 , and the adjustment grooves 53 are arranged lower than the slide groove 1 51 .

[0050] Reference Figure 6 , Figure 8 and Fig. 9The fastening block 27 is rotatably connected to the side wall away from the support plate 26 with a support wheel 271, and there is friction damping between the fastening block 27 and the support plate 26 to limit the free rotation of the support wheel 271. The inner side surfaces of the decorative surface 1 81 and the decorative surface 3 83 are both in contact with the support wheel 271, so that the support wheel 271 supports the aluminum single plate 8. The specific support wheel 271 is a rubber wheel. When the fastening block 27 fastens the aluminum single plate 8, the support wheel 271 is squeezed and deformed. The support plate 26 is horizontally slidably connected with an adjustment rod 262 that can abut against the inner side surface of the aluminum single plate 8. Two adjustment rods 262 are provided and are arranged at both ends of the support plate 26 in the horizontal direction. The opposite inner sides of the two adjustment rods 262 are fixedly connected with guide blocks 263. Two guide blocks 263 are provided and are arranged at both ends of the support plate 26 in the horizontal direction. The two guide blocks 263 are respectively located between the support plate 26 and the transmission rod 1 25 and between the support plate 26 and the transmission rod 2 93.

[0051] Before the aluminum plate 8 is transported to the spray gun 41, the roller 22 moves to the adjustment slot 53. Since the adjustment slot 53 is lower than the slide slot 51, the roller 22 pushes the guide block 263 to move horizontally toward the outside of the support plate 26 through the connecting rod 21, the guide block 23 and the transmission rod 25 in sequence. The adjustment rod 262 moves synchronously with the guide block 263 to push the aluminum plate 8 to move horizontally, so that the adjustment rod 262 adjusts the position of the aluminum plate 8 relative to the support plate 26 in the horizontal direction, and the support wheel 271 rotates with the movement of the aluminum plate 8. When the spray gun body sprays the real stone paint on the aluminum plate 8, the aluminum plate 8 remains stationary, thereby adjusting the position of the aluminum plate 8 relative to the support plate 26, that is, adjusting the position of the aluminum plate 8 relative to the spray gun body. When the aluminum plate 8 is stationary, the aluminum plate 8 is directly opposite to the spray gun body, which is conducive to improving the painting effect of the aluminum plate 8.

[0052] Reference Figure 2 and Fig.10 The bracket 1 is provided with a plurality of support members 7, the top wall of the support member 7 is fixedly connected with a rotation source 2 71, the driving shaft of the rotation source 2 71 is fixedly connected with a transmission screw 72, the transmission screw 72 is threadedly connected with a slider 73, the slider 73 is slidably connected to the support member 7, and the spray gun 1 41, the spray gun 2 42 and the spray gun 3 43 are respectively fixedly connected with a slider 73.

[0053] When there are multiple aluminum panels 8 in the vertical direction, the rotation source 2 71, the transmission screw 72 and the slider 73 form a screw slider mechanism. The rotation of the rotation source 2 71 drives the slider 73 to reciprocate in the vertical direction through the transmission screw 72. The spray gun 1 41, the spray gun 2 42 and the spray gun 3 43 all move synchronously with the slider 73 to spray paint the multiple aluminum panels 8 in the vertical direction.

[0054] The implementation principle of the surface spraying device of an imitation marble aluminum veneer of the embodiment of the present invention is as follows: the transport mechanism 3 drives the aluminum veneer 8 to move through the hanger 2, and the aluminum veneer 8 passes through the spray gun 1 41, the spray gun 2 42 and the spray gun 3 43 in sequence. When the aluminum veneer 8 moves synchronously with the hanger 2 to the spray gun 1 41, the spray gun 1 41 sprays the real stone paint to the decorative surface 2 82. When the transport mechanism 3 transports the aluminum veneer 8 to the spray gun 2 42 through the hanger 2, the roller 1 22 moves to the guide groove 1 52, and the roller 1 22 moves downward through the connecting rod 1 21, the guide block 1 23, and the guide inclined surface 2 231 to push the transmission rod 1 25 to move close to the support plate 26. The transmission rod 1 25 pushes the support plate 26 to rotate around the pin 29, and the support plate 26 drives the aluminum veneer 8 to rotate synchronously through the fastening block 27, and the decorative surface 1 81 rotates synchronously with the aluminum veneer 8 to face the spray gun 2 42, so that the spray gun 2 42 sprays the real stone paint on the decorative surface 1 81. Similarly, when the hanger 2 moves to the spray gun three 43, the aluminum single plate 8 rotates so that the decorative surface three 83 faces the spray gun three 43 arranged obliquely upward, and the spray gun three 43 sprays the decorative surface three 83 with real stone paint.

[0055] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense.

[0056] The above are preferred embodiments of the present invention. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
