Description

Technical Field

[0001] This utility model relates to the field of spraying, and in particular to an environmentally friendly paint recycling spraying equipment. Background Technology

[0002] With increasing automation, spray coating production lines are being used more and more widely, penetrating into many sectors of the national economy. Currently, spray coating equipment on the market can be categorized into three types based on its level of automation: manual spray coating equipment, semi-automatic spray coating equipment, and fully automatic spray coating equipment. Spray coating equipment is also known as coating equipment. Specifically, it refers to specialized tools used to cover metal and non-metal surfaces with protective or decorative layers. Based on the material being coated, it can be divided into four types: hardware spray coating equipment, plastic spray coating equipment, wood spray coating equipment, and ceramic spray coating equipment. Coating equipment uses a large amount of paint; any unused paint can be recycled and reused.

[0003] In existing technologies, workpieces made of materials such as plastics are relatively lightweight. When using recycled paint for spraying, they cannot achieve stability due to their own weight. Magnetic or hydraulic clamps are usually used to fix the workpiece in position. However, this method can easily leave indentations or deformation on the workpiece surface. Furthermore, the parts of the workpiece held by the hydraulic clamp need to be sprayed a second time. Repeated spraying operations can easily lead to secondary coating around the covered areas of the workpiece, resulting in uneven paint film thickness. If the paint is colored, color differences are likely to occur. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide an environmentally friendly paint recycling and spraying equipment to address the issue that, in the prior art, workpieces made of materials such as plastics are relatively light in weight, and when using recycled paint for spraying, they cannot achieve stability due to their own weight. Typically, magnetic or hydraulic clamps are used to fix the workpiece in position, but this method easily leads to indentations or deformation on the workpiece surface. Furthermore, the areas where the workpiece is held by the hydraulic clamp require secondary spraying, and repeated spraying operations easily result in secondary overlapping spraying around the covered areas of the workpiece, leading to uneven paint film thickness. If the paint is colored, color differences are likely to occur.

[0005] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0006] An environmentally friendly paint recycling spraying device includes: a base, a first support frame welded and fixed to one side of the upper end of the base, and a worktable provided on the upper end of the first support frame. An installation slot is opened on one side of the upper end of the worktable, and a limit frame is installed inside the installation slot. A reserved slot is opened inside the limit frame. A bearing is installed through the worktable corresponding to the lower side of the middle end of the limit frame, and a rotating shaft is installed through the bearing. A motor is installed at the lower end of the rotating shaft, and a rotating plate is installed at the upper end of the rotating shaft. A workpiece is placed on the upper end of the rotating plate.

[0007] A blower is provided on the side of the lower end of the workbench away from the motor, and a guide pipe is connected to one side of the blower. Diverter pipes are connected to both sides of the upper end of the guide pipe, and an air diffuser is provided at the end of the diverter pipe.

[0008] In one embodiment, a side mounting plate is welded and fixed to one side of the limiting frame, and the lower end of the side mounting plate contacts the upper end of the worktable.

[0009] In one embodiment, a mounting screw is provided through the inside of the side mounting plate, and the mounting screw extends into the worktable. The limiting frame and the side mounting plate form a detachable structure with the worktable through the mounting screw.

[0010] In one embodiment, two reserved slots are provided, and the inner shape of the two reserved slots matches the shape of the outer side of the workpiece.

[0011] In one embodiment, the upper end of the rotating shaft is welded and fixed to the lower end of the rotating plate, and the rotating plate forms a rotating structure with the motor through the rotating shaft.

[0012] In one embodiment, a first fixing frame is welded and fixed to the lower end of the motor, and one end of the first fixing frame is welded and fixed to the lower end of the worktable.

[0013] In one embodiment, an arc-shaped groove is provided on the upper end of the worktable along the rotation trajectory of the rotating plate, and a slide rail is provided inside the arc-shaped groove, with ball bearings inside the slide rail.

[0014] In one embodiment, inner limiting plates are provided on both sides of the upper end of the ball. The upper end of the inner limiting plate is welded and fixed to the bottom of the rotating plate. At least three sets of inner limiting plates are provided at equal intervals at the bottom of the rotating plate corresponding to the position of the slide rail. The inner limiting plates are used to limit the position of the ball at the bottom of the rotating plate when it rolls.

[0015] In one embodiment, the guide pipe extends through the interior of the workbench, and a second fixing frame is provided at the lower end of the blower, with one end of the second fixing frame welded and fixed to the lower end of the workbench.

[0016] In one embodiment, a second support frame is welded and fixed to the upper end of the base away from the first support frame, and a spraying machine is provided on the upper end of the second support frame. A connecting pipe is connected to the outside of the spraying machine, and a material storage tank is provided at the other end of the connecting pipe. A spiral guide pipe is connected to the side of the outside of the spraying machine corresponding to the connecting pipe, and a spray gun is provided at the other end of the spiral guide pipe.

[0017] This invention provides an environmentally friendly paint recycling spraying device. Compared with the prior art, it has the following advantages:

[0018] The workpiece is placed on the upper part of the rotating plate, with one side of the workpiece embedded in the reserved slot on one side of the limiting frame. At this point, one side of the workpiece can be sprayed with a spray gun. Because the workpiece is positioned by the limiting frame and the reserved slot, the workpiece will not shift due to the impact force during spraying, resulting in better spraying effect and more convenient operation. The combination of the limiting frame and the reserved slot achieves physical positioning, ensuring that the workpiece completely counteracts the reverse impact force or vibration interference generated by the high-pressure spray gun during spraying, avoiding displacement deviation. This rigid positioning method ensures that the spraying trajectory closely matches the preset path, making it particularly suitable for coating processes with complex surfaces or high precision requirements. The workpiece can be quickly aligned to the same position each time it is clamped. The motor on the upper part of the first fixed frame is started, driving the rotating shaft. The rotating shaft rotates inside the bearing, causing the rotating plate to rotate. The rotating plate rotates until the painted side of the workpiece is embedded in the reserved slot on the other side of the limiting frame. At this time, the motor stops running, and the spray gun is used again to spray the unpainted side of the workpiece. After one side of the workpiece is painted, the rotating shaft achieves high-precision axial movement with the support of the bearing, ensuring the smooth deflection of the rotating plate, so that the other side of the workpiece falls precisely into the reserved slot on the symmetrical side of the limiting frame, achieving seamless switching between the front and back sides. The other side of the workpiece can be fully painted without the need for tools such as clamps or manual fixation of the workpiece position. In traditional processes, magnetic or hydraulic clamps may leave indentations or deformations on the workpiece surface, and there is no need to separately paint small areas of the workpiece that are covered, avoiding color differences in areas with repeated painting.

[0029] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] Reference Figures 1-8An environmentally friendly paint recycling spraying device includes: a base 1, a first support frame 2 welded and fixed to one side of the upper end of the base 1, and a workbench 3 provided on the upper end of the first support frame 2. An installation slot 4 is opened on one side of the upper end of the workbench 3, and a limit frame 5 is installed inside the installation slot 4. A reserved slot 8 is opened inside the limit frame 5. A bearing 9 is installed through the workbench 3 corresponding to the lower middle position of the limit frame 5, and a rotating shaft 10 is installed through the bearing 9. A motor 11 is installed at the lower end of the rotating shaft 10, and a rotating plate 13 is installed at the upper end of the rotating shaft 10. A workpiece 14 is placed on the upper end of the rotating plate 13.

[0032] A blower 20 is provided on the side of the workbench 3 away from the motor 11, and a guide pipe 19 is connected to one side of the blower 20. A diversion pipe 22 is connected to both sides of the upper end of the guide pipe 19, and an air diffuser 23 is provided at the end of the diversion pipe 22.

[0033] A side mounting plate 6 is welded and fixed to one side of the limiting frame 5, and the lower end of the side mounting plate 6 contacts the upper end of the worktable 3.

[0034] A mounting screw 7 is installed through the inside of the side mounting plate 6, and the mounting screw 7 extends into the worktable 3. The limit frame 5 and the side mounting plate 6 form a disassembly structure with the worktable 3 through the mounting screw 7.

[0035] When spraying workpieces 14 with different shapes and structures is required, the mounting screws 7 in the side mounting plate 6 can be rotated and removed, and the limiting bracket 5 that matches the external shape of the workpiece 14 in the mounting slot 4 can be installed. The new limiting bracket 5 is placed in the mounting slot 4 of the worktable 3. Both the side mounting plate 6 and the worktable 3 are provided with threaded holes corresponding to the mounting screws 7. Then, the mounting screws 7 are rotated and fixed into the threaded holes of the side mounting plate 6 and the worktable 3 to complete the installation of the new limiting bracket 5. This structure can realize the auxiliary spraying processing of workpieces 14 with different shapes and structures on the worktable 3. The limiting bracket 5 can be customized and replaced according to the shape of the workpiece 14 (such as irregular parts with different cross-sectional contours). Only the size of the slot needs to be adjusted to adapt to new products.

[0036] There are two reserved slots 8, and the inner shape of the two reserved slots 8 matches the shape of the outer side of the workpiece 14.

[0037] The workpiece 14 is placed on the upper end of the rotating plate 13, and one side of the workpiece 14 is embedded in the reserved slot 8 on one side of the limiting frame 5. At this time, one side of the workpiece 14 can be sprayed with a spray gun 29. The storage tank 27 contains recycled paint, which is introduced into the spraying machine 25 through the connecting pipe 26, and then discharged through the spiral guide pipe 28. The workpiece 14 is then sprayed with the spray gun 29. At this time, when spraying the workpiece 14, the limiting frame 5 and the reserved slot 8 on one side of the workpiece 14 ensure that the workpiece 14 is properly positioned. The position is limited so that the workpiece 14 will not shift due to the impact force during spraying, resulting in better spraying effect and more convenient spraying operation. Physical limitation is achieved by the combination of the limiting frame 5 and the reserved slot 8, ensuring that the workpiece 14 completely offsets the reverse impact force or vibration interference generated by the high-pressure spray gun 29 during the spraying process, avoiding displacement deviation. This rigid positioning method makes the spraying trajectory highly consistent with the preset path, which is especially suitable for coating processes with complex surfaces or high precision requirements. The workpiece 14 can be quickly aligned to the same position each time it is clamped.

[0038] The upper end of the rotating shaft 10 is welded and fixed to the lower end of the rotating plate 13. The rotating plate 13 and the motor 11 form a rotating structure through the rotating shaft 10.

[0039] A first fixing frame 12 is welded and fixed to the lower end of the motor 11, and one end of the first fixing frame 12 is welded and fixed to the lower end of the worktable 3.

[0040] The motor 11 at the upper end of the first fixed frame 12 is started. The motor 11 drives the rotating shaft 10 to rotate inside the bearing 9. The rotation of the rotating shaft 10 drives the rotating plate 13 to rotate. The rotating plate 13 rotates until the painted side of the workpiece 14 is embedded in the reserved slot 8 on the other side of the limiting frame 5. At this time, the motor 11 stops running. The spray gun 29 is used again to spray the unpainted side of the workpiece 14. After the painting of one side of the workpiece 14 is completed, the rotating shaft 10 achieves high-precision axial movement with the support of the bearing 9, ensuring the smooth deflection of the rotating plate 13. This allows the other side of the workpiece 14 to fall precisely into the reserved slot 8 on the symmetrical side of the limiting frame 5, achieving seamless switching between the front and back sides. The other side of the workpiece 14 can be fully painted without the need for clamps or other tools or manual fixation of the workpiece 14. In traditional processes, magnetic or hydraulic clamps may leave indentations or deformation on the surface of the workpiece 14. Furthermore, it eliminates the need for separate painting of small covered areas of the workpiece 14, avoiding color differences in areas with repeated painting.

[0041] An arc-shaped groove 18 is provided on the upper end of the worktable 3 along the rotation trajectory of the rotating plate 13, and a slide rail 17 is provided on the inner side of the arc-shaped groove 18, with ball bearings 16 inside the slide rail 17.

[0042] Inner limit plates 15 are provided on both sides of the upper end of the ball 16. The upper end of the inner limit plate 15 is welded and fixed to the bottom of the rotating plate 13. At least three sets of inner limit plates 15 are provided at equal intervals at the bottom of the rotating plate 13 corresponding to the position of the slide rail 17. The inner limit plates 15 are used to limit the position of the ball 16 at the bottom of the rotating plate 13 when it rolls.

[0043] The ball bearings 16 at the bottom of the rotating plate 13 roll along the slide rail 17 in the arc groove 18 of the worktable 3, converting sliding friction into rolling friction, which significantly reduces the driving force requirement and reduces mechanical wear; together with the limiting function of multiple sets of inner limit plates 15, it ensures that the ball bearings 16 always run stably within the track, eliminating the risk of derailment.

[0044] The guide pipe 19 passes through the interior of the workbench 3, and a second fixed frame 21 is provided at the lower end of the blower 20, and one end of the second fixed frame 21 is welded and fixed to the lower end of the workbench 3.

[0045] A second support frame 24 is welded and fixed to the upper end of the base 1 on the side away from the first support frame 2. A sprayer 25 is installed on the upper end of the second support frame 24. A connecting pipe 26 is connected to one side of the outside of the sprayer 25, and a material storage tank 27 is installed at the other end of the connecting pipe 26. A spiral guide pipe 28 is connected to the side of the outside of the sprayer 25 corresponding to the connecting pipe 26, and a spray gun 29 is installed at the other end of the spiral guide pipe 28.

[0046] During use, the workpiece 14 is first placed on the upper end of the rotating plate 13, with one side of the workpiece 14 embedded in the reserved slot 8 on one side of the limiting frame 5. At this point, one side of the workpiece 14 can be sprayed using the spray gun 29. Recycled paint is placed in the storage tank 27 and introduced into the spraying machine 25 (model W71-1S) through the connecting pipe 26. Then, it is discharged through the spiral guide pipe 28 and sprayed onto the workpiece 14 using the spray gun 29. During spraying, because the limiting frame 5 and the reserved slot 8 on one side of the workpiece 14 limit its position, the workpiece 14 will not shift due to the impact during spraying, resulting in a better spraying effect. The spraying operation is more convenient. After one side of the workpiece 14 is sprayed, the blower 20 at the upper end of the second fixed frame 21 is started. The blower 20 starts, and the airflow enters the diversion pipe 22 through the guide pipe 19, and finally is led out by the air diffuser 23 to blow air onto the outside of the workpiece 14, accelerating the drying of the coating on the outside of the workpiece 14. After the coating on the outside of the workpiece 14 is dried, the motor 11 at the upper end of the first fixed frame 12 is started. The motor 11 starts and drives the rotating shaft 10 to rotate inside the bearing 9. The rotation of the rotating shaft 10 drives the rotating plate 13 to rotate. The rotating plate 13 rotates until the side of the workpiece 14 that has been sprayed is embedded into the reserved slot 8 on the other side of the limiting frame 5. When the rotating plate 13 rotates, the bottom of the rotating plate 13... The ball bearing 16 can rotate along the slide rail 17, which is set in the arc groove 18 of the worktable 3. Multiple sets of inner limit plates 15 are provided at the bottom of the rotating plate 13 to limit the position of the ball bearing 16 during rotation, ensuring that the ball bearing 16 will not come off at the bottom of the rotating plate 13. Furthermore, the ball bearing 16 is designed to convert sliding friction into rolling friction, significantly reducing the driving force requirement and mechanical wear. At this time, the motor 11 stops running, and the spray gun 29 is used again to spray the uncoated side of the workpiece 14. The second fixed frame 21 at the bottom of the blower 20 is welded and fixed to the worktable 3, and the first fixed frame 12 at the lower end of the motor 11 is welded and fixed to the worktable 3. The first support frame 2 at the lower end of the worktable 3 is... The base 1 is welded and fixed. The second support frame 24 at the lower end of the spraying machine 25 is welded and fixed to the base 1. When it is necessary to spray the workpiece 14 with different shapes and structures, the mounting screw 7 in the side mounting plate 6 can be rotated and removed. The limit frame 5 that matches the external shape of the workpiece 14 can be replaced and installed. The new limit frame 5 is placed in the mounting slot 4 of the worktable 3. The side mounting plate 6 and the worktable 3 are provided with threaded holes corresponding to the mounting screw 7. Then, the mounting screw 7 is rotated and fixed into the threaded holes of the side mounting plate 6 and the worktable 3 to complete the installation of the new limit frame 5. This structure can realize the auxiliary spraying processing of workpieces 14 with different shapes and structures on the worktable 3.
