Description

Technical Field

[0001] This utility model relates to the field of sheet metal spraying technology, and more specifically, to a sheet metal spraying device. Background Technology

[0002] In existing technologies, panel spraying, as a common surface treatment process in industrial production, is widely used in furniture manufacturing, building decoration, automotive parts, and other fields. Spraying paint onto panel surfaces can improve the product's aesthetics, corrosion resistance, and service life. Existing panel spraying equipment typically includes components such as paint storage tanks, delivery pipelines, and spray nozzles. Paint is transported from the storage tank to the spray nozzles via the delivery pipelines for spraying. However, in existing technologies, paint delivery is usually at a fixed flow rate, and the delivery pipelines are set with constant operating parameters. This makes it impossible to flexibly adjust the paint delivery flow rate according to the material characteristics, specifications, or spraying process requirements of different panels. As a result, when spraying thin panels, the paint flow rate may be too fast, leading to an excessively thick coating and sagging. When spraying thick panels or large-area panels, the paint flow rate may be too slow, resulting in low spraying efficiency or uneven coating thickness, affecting spraying quality and production efficiency.

[0003] Secondly, although some existing spraying equipment achieves flexible adjustment of paint delivery speed by setting up some components in the delivery pipeline, and operators can manually adjust parameters to change the paint flow rate according to actual spraying needs, the adjustment structure of these devices is relatively simple and usually lacks stability. During the spraying operation, external forces such as vibration of the delivery pipeline, paint pressure impact, or external collisions can easily cause the adjusted structure and components to loosen or shift, resulting in fluctuations or deviations of the adjusted delivery speed from the preset value. This leads to unstable coating thickness, affecting product quality, and requires operators to frequently readjust, increasing workload and reducing production efficiency. Utility Model Content

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides a sheet metal spraying device to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a sheet metal spraying device, comprising a lifting assembly and an atomizing nozzle, wherein the atomizing nozzle is movably mounted on one side of the lifting assembly, and a flow tube is detachably connected to the top of the atomizing nozzle; a regulating sleeve and a conveying pipe are provided on one side of the flow tube; the two ends of the regulating sleeve are rotatably connected to the flow tube and the conveying pipe, respectively; multiple motion slots are provided on one side of the regulating sleeve; an adjusting plate is movably provided inside the regulating sleeve; an adjusting shaft and a connecting shaft are rotatably mounted on the adjusting plate; a mating plate is rotatably provided outside the conveying pipe; a mating hole is provided on the mating plate; multiple motion frames are fixedly provided outside the conveying pipe; a motion rod is rotatably provided inside the motion frame; one end of the motion rod is inserted into a motion slot; a motion sleeve is provided outside the conveying pipe; a push rod is connected to one side of the motion sleeve; and a guide slot is provided on one side of the flow tube.

[0006] The present invention is further configured such that a frame is provided on the outside of the lifting assembly, and a placement platform is detachably provided on the inside of the frame.

[0007] The present invention is further configured such that a longitudinal moving component is detachably provided at the top of the frame, a transverse moving component is movably provided above the longitudinal moving component, and a lifting component is movably installed on one side of the transverse moving component.

[0008] The present invention is further configured such that one end of the adjusting shaft slides in the guide groove, and one end of the connecting shaft is rotatably connected to the inner wall of the adjusting sleeve.

[0009] The present invention is further configured such that one end of the sports sleeve adopts a chamfered structure design.

[0010] The present invention is further configured such that the adjusting plate has multiple flow holes.

[0011] The present invention is further configured such that a push spring is connected to one side of the moving sleeve, the other end of the push spring abuts against one side of the mating plate, and the push spring is movably sleeved on the outside of the push rod.

[0012] The present invention is further configured such that the inner wall of the motion groove and both ends of the motion rod are designed with rounded corners.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a sheet metal spraying device, which has the following beneficial effects: 1. By installing a regulating sleeve on one side of the flow tube and a movable regulating plate inside the regulating sleeve, and simultaneously mounting an regulating shaft and a connecting shaft on the regulating plate so that one end of the regulating shaft slides in the guide groove and the other end of the connecting shaft is rotatably connected to the inner wall of the regulating sleeve, and multiple flow holes are opened on the regulating plate, a flexible and adjustable paint flow rate adjustment mechanism is formed. During the spraying operation, the operator rotates the regulating sleeve forward according to the material of the board and the process requirements. The regulating sleeve drives the regulating plate to move through the connecting shaft, causing the regulating plate to drive the regulating shaft to spread outward along the guide groove. The outward movement of the regulating plate drives the flow holes to move. By adjusting the diffusion motion of the regulating plate to change the flow area inside the flow tube, the coating speed can be changed, enabling flexible adjustment of the coating delivery rate. Compared with traditional equipment with a fixed flow rate, operators can reduce the flow area and lower the flow rate according to actual application needs to avoid excessive coating thickness and sagging, or increase the flow area and increase the flow rate to improve spraying efficiency for thick and large-area plates. This effectively solves the problem of the fixed flow rate of coating delivery in existing technologies, which cannot be flexibly adjusted according to different material characteristics, specifications or process requirements of different plates, resulting in a decrease in spraying quality and efficiency. It improves the range of coating flow rate adjustment and ensures production efficiency.

[0014] 2. By fixing multiple moving frames on the outside of the conveying pipe and rotating moving rods on the inside of the moving frames, one end of the moving rods is engaged in a moving groove on one side of the regulating sleeve. Simultaneously, a moving sleeve is set on the outside of the conveying pipe, and a push rod is connected to one side of the moving sleeve. A mating plate is rotated on the outside of the conveying pipe, with mating holes on the mating plate. A push spring connected to one side of the mating sleeve abuts against the mating plate, and the push spring is movably sleeved on the outside of the push rod, forming a multi-locking adjustment and stabilization mechanism. After the operator adjusts the paint conveying flow rate, the push rod supports the moving sleeve to one side of the mating plate, preventing the moving sleeve from easily sliding. Together with the motion rod, motion frame, and motion groove, it forms a rotation limit for the control sleeve to prevent accidental rotation of the control sleeve. Compared with traditional adjustment devices with simple structure and lack of stability, this invention effectively resists external forces such as vibration of the conveying pipeline, pressure impact of the coating, or external collisions during the spraying operation through multiple locking mechanisms. It effectively solves the problem that the existing technology has a simple adjustment structure that is prone to loosening or displacement due to external forces, causing the conveying flow rate to fluctuate from the preset value, resulting in unstable coating thickness, affecting quality, and requiring frequent readjustment. It reduces the flow rate fluctuation rate, ensures the continuous stability of the spraying operation, reduces the frequency of operator adjustments, and improves production efficiency.

[0020] Please see Figures 1-5A sheet metal spraying device includes a lifting assembly 1 and an atomizing nozzle 2. The atomizing nozzle 2 is movably installed on one side of the lifting assembly 1. A flow tube 3 is detachably connected to the top of the atomizing nozzle 2. A control sleeve 4 and a conveying pipe 5 are provided on one side of the flow tube 3. The two ends of the control sleeve 4 are rotatably connected to the flow tube 3 and the conveying pipe 5, respectively. Multiple motion grooves 6 are opened on one side of the control sleeve 4. An adjustment plate 7 is movably provided inside the control sleeve 4. An adjustment shaft 8 and a connecting shaft 9 are rotatably installed on the adjustment plate 7. A mating plate 10 is rotatably provided outside the conveying pipe 5. A mating hole 11 is opened on the mating plate 10. Multiple motion frames 12 are fixedly provided outside the conveying pipe 5. A motion rod 13 is rotatably provided inside the motion frame 12. One end of the motion rod 13 is inserted into the motion groove 6. A motion sleeve 14 is provided outside the conveying pipe 5. A push rod 15 is connected to one side of the motion sleeve 14. A guide groove 16 is opened on one side of the flow tube 3.

[0021] The lifting assembly 1 has a frame 17 on the outside and a detachable placement platform 18 on the inside of the frame 17.

[0022] The top of the frame 17 is detachably provided with a longitudinal moving component 19, and a transverse moving component 20 is movably provided above the longitudinal moving component 19. The lifting component 1 is movably installed on one side of the transverse moving component 20.

[0023] In this embodiment, when the device is needed, the board is first placed on the placement platform 18, and the board can be properly clamped and fixed using the external fixing components. Then, the external paint delivery component is opened to deliver the paint to the delivery pipe 5, and then through the delivery pipe 5, flow pipe, and other components, it is delivered to the atomizing nozzle 2, so that the paint is atomized and sprayed out through the atomizing nozzle 2. Then, the longitudinal movement component 19 can be opened to drive the atomizing nozzle 2 and other components to move longitudinally, and then the transverse movement component 20 can be opened to drive the atomizing nozzle 2 and other components to move laterally, so as to achieve full spraying of one side of the board. Then, the height of the atomizing nozzle 2 can be appropriately adjusted by the lifting component 1. The delivery pipe 5 is connected to the external paint delivery component through the external corrugated hose to adapt to the movement of the atomizing nozzle 2. When it is necessary to control the paint delivery flow rate, first, the mating plate 10 is rotated forward, so that the mating plate 10 drives the mating hole 11 to rotate to the concentric position with the push rod 15. Then, the moving sleeve 14 is pushed, so that the moving sleeve 14 drives the push rod 15 on one side to gradually move. The sliding sleeve 14 gradually slides into the mating hole 11, and the moving sleeve 14 cooperates with the mating plate 10 to gradually compress the push spring 22. At the same time, the moving sleeve 14 gradually stops limiting one end of the moving rod 13. Then, the regulating sleeve 4 is rotated in the forward direction, which drives the multiple moving grooves 6 opened on one side to rotate. Then, the inner wall of the moving groove 6 compresses one end of the moving rod 13. Due to the rounded corner design of the inner wall of the moving groove 6 and the end of the moving rod 13, as well as the rotational connection between the moving rod 13 and the moving frame 12, the moving groove 6 will then compress one end of the moving rod 13. The extrusion at one end causes the moving rod 13 to rotate within the moving frame 12, and the other end of the moving rod 13 to rotate inward. Simultaneously, the regulating sleeve 4 drives the inner adjusting plate 7 to move via the connecting shaft 9. This causes the adjusting plate 7 to drive the adjusting shaft 8 on the other side to spread outward along the guide groove 16, causing the adjusting plate 7 to move outward and drive the flow hole 21 to move. The movement of the flow hole 21, in conjunction with the diffusion movement of the adjusting plate 7, changes the internal flow area of ​​the flow tube 3, thereby changing the flow rate of the coating.

[0024] Please see Figures 3-5 As a further implementation of the overall equipment: one end of the adjusting shaft 8 is slidably placed in the guide groove 16, and one end of the connecting shaft 9 is rotatably connected to the inner wall of the regulating sleeve 4.

[0025] The sports sleeve 14 features a chamfered design at one end.

[0026] The regulating plate 7 has multiple flow holes 21.

[0027] A push spring 22 is connected to one side of the moving sleeve 14, and the other end of the push spring 22 abuts against one side of the mating plate 10. The push spring 22 is movably sleeved on the outside of the push rod 15.

[0028] The inner wall of the motion groove 6 and both ends of the motion rod 13 are designed with rounded corners.

[0029] More specifically, once the paint flow rate is adjusted to a suitable level, the control sleeve 4 is stopped from rotating, causing it to rotate the corresponding motion groove 6 to the position corresponding to the motion rod 13. At this point, the motion sleeve 14 is released, and the push spring 22 resets, pushing the motion sleeve 14. This causes the motion sleeve 14 to slide and reset one side of the push rod 15. Simultaneously, due to the chamfered design at one end of the motion sleeve 14 and the rounded corner design at the end of the motion rod 13, the motion sleeve 14 gradually pushes the corresponding end of the motion rod 13 outward. Then, the motion rod 13 rotates in the opposite direction within the motion frame 12, re-engaging the other end of the motion rod 13 into the original motion groove 6. The moving sleeve 14 drives the push rod 15 to fully reset, so that the push rod 15 no longer passes into the mating hole 11. Then, the mating plate 10 is rotated in the opposite direction, so that the mating plate 10 drives the mating hole 11 to rotate in the opposite direction and reset to a position that does not correspond to the push rod 15. Then, the push rod 15 supports the moving sleeve 14 to one side of the mating plate 10, so that the moving sleeve 14 cannot slide easily. At this time, the moving sleeve 14, the moving rod 13, the moving frame 12 and the moving groove 6 work together to form a rotation limit on the regulating sleeve 4, preventing the regulating sleeve 4 from rotating accidentally, thereby ensuring the structural stability after the paint conveying flow rate is regulated, ensuring the stable delivery of paint, and thus ensuring the stable operation of the spraying work.

[0030] In summary, when using or operating the equipment: First, place the sheet material on the placement platform 18, and use the external fixing components to clamp and fix the sheet material appropriately. Then, open the external paint delivery component to deliver the paint to the delivery pipe 5, and then deliver it to the atomizing nozzle 2 through the delivery pipe 5, flow pipe, and other components, so that the paint is atomized and sprayed out through the atomizing nozzle 2. Then, open the longitudinal movement component 19 to drive the atomizing nozzle 2 and other components to move longitudinally, and then open the transverse movement component 20 to drive the atomization... The nozzle 2 and other components move laterally to achieve full spraying of one side of the board. The height of the atomizing nozzle 2 can be adjusted appropriately by the lifting assembly 1. The delivery pipe 5 is connected to the external paint delivery assembly through an external corrugated hose to accommodate the movement of the atomizing nozzle 2. When it is necessary to control the paint delivery rate, firstly, the mating plate 10 is rotated forward, causing the mating hole 11 to rotate to a position concentric with the push rod 15. Then, the moving sleeve 14 is pushed, causing the moving sleeve 14 to drive one side of the push rod. As rod 15 gradually slides into mating hole 11, the moving sleeve 14, in conjunction with mating plate 10, gradually compresses the push spring 22. Simultaneously, the moving sleeve 14 gradually ceases to limit one end of moving rod 13. Then, the regulating sleeve 4 rotates forward, causing multiple moving grooves 6 on one side to rotate. The inner wall of the moving grooves 6 then compresses one end of moving rod 13. Due to the rounded corners of the inner wall of the moving grooves 6 and the end of moving rod 13, as well as the rotating connection between moving rod 13 and moving frame 12, the moving grooves 6 will then compress the moving rod 15. One end of the extrusion causes the moving rod 13 to rotate in the moving frame 12, and the other end of the moving rod 13 to rotate inward. At the same time, the regulating sleeve 4 drives the inner regulating plate 7 to move through the connecting shaft 9, so that the regulating plate 7 drives the regulating shaft 8 set on the other side to diffuse outward along the guide groove 16, so that the regulating plate 7 diffuses outward and drives the flow hole 21 to move. The movement of the flow hole 21, together with the diffusion movement of the regulating plate 7, changes the internal flow area of ​​the flow tube 3, thereby changing the flow speed of the coating.

[0031] Once the paint flow rate is adjusted to a suitable level, the control sleeve 4 is stopped from rotating, causing it to rotate the corresponding motion groove 6 to the position corresponding to the motion rod 13. At this point, the motion sleeve 14 is released, and the push spring 22 resets, pushing the motion sleeve 14. This causes the motion sleeve 14 to slide and reset one side of the push rod 15. Simultaneously, due to the chamfered design at one end of the motion sleeve 14 and the rounded corner design at the end of the motion rod 13, the motion sleeve 14 gradually pushes the corresponding end of the motion rod 13 outwards. The motion rod 13 then rotates in the opposite direction within the motion frame 12, re-engaging the other end of the motion rod 13 into the original motion groove 6. The sleeve 14 drives the push rod 15 to fully reset, so that the push rod 15 no longer passes into the mating hole 11. Then, the mating plate 10 is rotated in the opposite direction, so that the mating plate 10 drives the mating hole 11 to rotate in the opposite direction and reset to a position that does not correspond to the push rod 15. Then, the push rod 15 supports the moving sleeve 14 to one side of the mating plate 10, so that the moving sleeve 14 cannot slide easily. At this time, the moving sleeve 14, the moving rod 13, the moving frame 12 and the moving groove 6 work together to form a rotation limit on the regulating sleeve 4, preventing the regulating sleeve 4 from rotating accidentally, thereby ensuring the structural stability after the paint conveying flow rate is regulated, ensuring the stable delivery of paint, and thus ensuring the stable operation of the spraying work.
