Description

Technical Field

[0001] This utility model relates to the technical field of metal processing, and in particular to a metal spraying device. Background Technology

[0002] Metals come in many forms, such as metal pipes and metal plates. When processing metal pipes, in order to improve their corrosion resistance, aesthetics, or to meet specific functional requirements, a spraying device is needed to spray the outer wall of the metal pipe.

[0003] When spraying metal pipes, clamps are used to hold and fix the outer walls of both ends of the pipe. However, while this method ensures the stability of the pipe during spraying, the areas obscured by the clamps cannot be effectively sprayed. This necessitates additional time and procedures to treat these unsprayed areas after the initial spraying, thus increasing the workload. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to provide a metal spraying device that can support and fix the metal tube from the inside, ensuring that the spraying operation is not obstructed, so that the outer wall of the metal tube can be fully sprayed, thereby effectively reducing the workload.

[0006] To achieve the above objectives, this utility model proposes a metal spraying device, comprising a base, an electric slide rail, a spraying mechanism, a supporting mechanism, and two arc-shaped support plates. The electric slide rail is disposed on the top surface of the base and connected to an electric push rod. The spraying mechanism is connected to the piston end of the electric push rod. A rotary driver is provided on the top surface of the base, and the output end of the rotary driver is connected to a turntable. A cylindrical body is disposed at the center of the upper surface of the turntable, located on one side of the spraying mechanism. The supporting mechanism is disposed inside and on the upper surface of the cylindrical body, with both ends passing through the side walls of the cylindrical body and connected to the two arc-shaped support plates.

[0007] The metal spraying device of this invention can support and fix the metal tube from the inside, ensuring that the spraying operation is not obstructed, so that the outer wall of the metal tube can be fully sprayed, thereby effectively reducing the workload.

[0008] In addition, the metal spraying apparatus proposed in the application may also have the following additional technical features:

[0009] Specifically, the spraying mechanism includes an arc-shaped housing, multiple nozzles, and a delivery hose. The arc-shaped housing is connected to the piston end of the electric push rod, the multiple nozzles are respectively connected to the inner wall of the arc-shaped housing, and the delivery hose is connected to the arc-shaped housing.

[0010] Specifically, the supporting mechanism includes a bidirectional screw, two sliders, a guide rod, four connecting rods, two movable columns, and a driving component. The bidirectional screw is rotatably disposed within the cylinder. The two sliders are threadedly connected to the center sides of the bidirectional screw, respectively. The guide rod is disposed between the top and bottom walls of the cylinder. The two sliders are slidably connected to the guide rod, respectively. The connecting rods are hinged between the sliders and the movable columns. The two movable columns pass through the side walls of the cylinder and are connected to the two arc-shaped support plates. The driving component is disposed on the upper surface of the cylinder, and its output end is connected to the bidirectional screw.

[0011] Specifically, the upper surface of the turntable is provided with an annular groove, and an annular collection groove is provided in the annular groove, the annular collection groove extending above the annular groove.

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The metal spraying apparatus of this utility model embodiment will now be described with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the metal spraying device of this utility model embodiment may include a base 10, an electric slide rail 20, a spraying mechanism 40, a supporting mechanism 60, and two arc-shaped support plates 70. The electric slide rail 20 is disposed on the top surface of the base 10 and is connected to an electric push rod 30. The spraying mechanism 40 is connected to the piston end of the electric push rod 30. A rotary driver 51 is disposed on the top surface of the base 10. The output end of the rotary driver 51 is connected to a turntable 52. A cylinder 53 is disposed at the center of the upper surface of the turntable 52. The cylinder 53 is located on one side of the spraying mechanism 40. The supporting mechanism 60 is disposed inside the cylinder 53 and on its upper surface. The two ends of the supporting mechanism 60 pass through the side wall of the cylinder 53 and are connected to the two arc-shaped support plates 70.

[0023] Specifically, the staff first moves the metal tube to be sprayed from above the cylinder 53 downwards until it is close to the turntable 52. During this process, the metal tube is located on the outside of the cylinder. Then, the support mechanism 60 is activated, which drives the two arc-shaped support plates 70 to move, so that the two arc-shaped support plates 70 fit against the inner wall of the metal tube respectively, clamping and fixing the metal tube.

[0024] Then, the electric push rod 30 is activated, bringing the spraying mechanism 40 close to the metal tube. The rotary driver 51 is then activated, causing the turntable 52 and its cylinder 53 to rotate, thus rotating the metal tube. At the same time, the spraying mechanism 40 is activated to evenly spray the rotating metal tube. Then, the electric slide rail 20 is activated, causing the spraying mechanism 40 to move up and down to fully spray the metal tube.

[0025] Once the surface of the metal tube reaches the desired coating thickness, the operation of the rotary drive 51 and the spraying mechanism 40 is stopped. Then, the support mechanism 60 is activated, which drives the two arc-shaped support plates 70 to release the metal tube from its fixation. The worker then lifts the sprayed metal tube upwards.

[0026] The metal spraying device of this utility model can support and fix the metal tube from the inside, ensuring that the spraying operation is not obstructed, so that the outer wall of the metal tube can be fully sprayed, thereby effectively reducing the workload.

[0027] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the spraying mechanism 40 may include an arc-shaped housing 41, multiple nozzles 42 and a delivery hose 43. The arc-shaped housing 41 is connected to the piston end of the electric push rod 30, the multiple nozzles 42 are respectively connected to the inner wall of the arc-shaped housing 41, and the delivery hose 43 is connected to the arc-shaped housing 41.

[0028] It should be noted that the delivery hose 43 is connected to an external paint pump. The paint in the paint storage tank is delivered to the arc-shaped housing 41 through the delivery hose 43 by the paint pump. The arc-shaped housing 41 temporarily stores the paint, and then the arc-shaped housing 41 sprays the paint onto the surface of the metal pipe through multiple nozzles 42.

[0029] In one embodiment of this utility model, such as Figure 3 As shown, the supporting mechanism 60 includes a bidirectional screw 61, two sliders 62, a guide rod 63, four connecting rods 64, two movable columns 65, and a driving component 66. The bidirectional screw 61 is rotatably disposed inside the cylinder 53. The two sliders 62 are threadedly connected to the center sides of the bidirectional screw 61, respectively. The guide rod 63 is disposed between the top and bottom walls of the cylinder 53. The two sliders 62 are slidably connected to the guide rod 63, respectively. The connecting rods 64 are hinged between the sliders 62 and the movable columns 65. The two movable columns 65 pass through the side walls of the cylinder 53 and are connected to two arc-shaped support plates 70, respectively. The driving component 66 is disposed on the upper surface of the cylinder 53, and the output end of the driving component 66 is connected to the bidirectional screw 61.

[0030] It should be noted that the driving component 66 described in this embodiment can be a motor. The guide rod 63 passes through the slider 62, and the slider 62 is slidably connected to the guide rod 63. The driving component 66 can drive the bidirectional screw 61 to rotate, thereby driving the two sliders 62 to move towards each other. During this process, the guide rod 63 provides guidance for the sliders 62. The two sliders 62 drive the four connecting rods 64 to move, and the four connecting rods 64 drive the two moving columns 65 to move towards each other, thereby driving the two arc-shaped support plates 70 to fit against the inner wall of the metal tube and clamp and fix them.

[0031] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, an annular groove 81 is provided on the upper surface of the turntable 52, and an annular collection groove 82 is provided in the annular groove 81, which extends above the annular groove 81.

[0032] It is understandable that by setting up the annular collection tank 82, the paint spilled during the spraying process can be collected, making it easier to reuse the paint, avoiding material waste, and keeping the working environment clean. After the spraying is completed, the annular collection tank 82 is removed from the annular groove 81, and the paint inside is processed.

[0033] In one embodiment of this utility model, such as Figure 3 As shown, an anti-slip pad 71 is connected to the outer side of the arc-shaped support plate 70.

[0034] Understandably, by setting the anti-slip pad 71, the friction between the pad and the inner wall of the metal tube can be increased, resulting in a better fixing effect. Furthermore, the anti-slip pad 71 is made of soft material, which can prevent hard materials from scratching the inner wall of the metal tube.

[0035] In summary, the metal spraying device of this utility model embodiment can support and fix the metal tube from the inside, ensuring that the spraying operation is not obstructed, so that the outer wall of the metal tube can be fully sprayed, thereby effectively reducing the workload.
