Description

Technical Field

[0001] This application relates to the field of anti-oxidation spraying technology for cold-rolled thin plates, specifically an anti-oxidation spraying device for cold-rolled thin plates. Background Technology

[0002] Cold-rolled sheet metal is widely used in the automotive, home appliance, and construction industries due to its high strength and good surface quality. However, during production, storage, and subsequent processing, the surface of cold-rolled sheet metal is prone to oxidation with oxygen in the air, forming an oxide layer. This not only reduces the sheet's corrosion resistance and mechanical properties but also affects the quality of subsequent coating and welding processes. Therefore, applying an anti-oxidation spray coating to cold-rolled sheet metal is a crucial step in ensuring its performance and service life.

[0003] Workers often operate by hand with spray guns. For large-sized cold-rolled thin plates (such as plates with a length exceeding 2m and a width exceeding 50cm), it is difficult to accurately control the range and speed of manually moving the spray gun. The labor intensity is extremely high, and it is easy to cause uneven spraying or even missed spraying due to physical exhaustion or operator fatigue, which seriously affects the anti-oxidation effect. At the same time, paint splashing is difficult to control, which not only pollutes the working environment and increases cleaning costs, but may also threaten the health of workers.

[0004] Therefore, this application provides an anti-oxidation spraying device for cold-rolled thin plates to solve the above problems. Utility Model Content

[0005] This application provides a cold-rolled thin plate anti-oxidation spraying device, which aims to solve the problems mentioned in the background art, such as the difficulty in accurately controlling the range and speed of manually moving the spray gun, the extreme labor intensity, and the easy occurrence of uneven spraying due to physical exhaustion or operator fatigue.

[0006] To achieve the above objectives, this application provides the following technical solution: a cold-rolled sheet anti-oxidation spraying device, comprising a support frame and a plurality of legs equidistantly installed at the bottom of the support frame, wherein a spraying assembly is provided at the upper end of the support frame and a cold-rolled sheet body is provided at the upper end of the support frame;

[0007] The spraying assembly includes a material tank mounted on a support plate, a pump body connected to the material tank at the lower end of the support plate, a guide pipe mounted on the back of the material tank, and a discharge pipe mounted on the side of the pump body via a clamp seat. The discharge port of the guide pipe is connected to the inlet of the discharge pipe.

[0008] The support frame is equipped with an adjustment mechanism;

[0009] The adjustment mechanism includes fixed seats symmetrically mounted on a support frame. A guide rod is fixedly mounted on a fixed seat on one side of the support frame, and a threaded rod is rotatably connected to a fixed seat on the other side of the support frame. Fixed frames are symmetrically mounted on the support plate, and reinforcing frames are fixedly mounted on each fixed frame. Connecting seats for sleeved with the threaded rod and the guide rod are fixedly mounted on the reinforcing frames respectively.

[0010] Preferably, a material distribution plate is fixedly installed at the outlet of the discharge pipe, and a number of nozzles are evenly distributed at the lower end of the material distribution plate, so that wide and uniform spraying can be achieved through the material distribution plate and multiple nozzles.

[0011] Preferably, the connecting seat at the end away from the guide rod is threadedly fitted to the threaded rod, and a servo motor is installed on the fixed seat near the threaded rod, with the output end of the servo motor fixedly connected to one end of the threaded rod.

[0012] Preferably, the upper end of the support frame is symmetrically provided with anti-splash plates for clamping the cold-rolled sheet body. The anti-splash plates are composed of vertical plates and inclined plates, which also help to fix the cold-rolled sheet and prevent the sheet from shifting during spraying.

[0013] Preferably, both ends of the support frame are provided with positioning seats, and a bidirectional lead screw is rotatably connected to the positioning seats distributed opposite each other at one end of the support frame. The end of the splash guard near the bidirectional lead screw is threaded onto it, and one end of the bidirectional lead screw passes through the positioning seat, with a torsion wheel fixedly installed at the passage.

[0014] Preferably, a limiting rod is fixedly connected to a positioning seat distributed opposite to the other end of the support frame, and the end of the splash guard near the limiting rod is movably sleeved with it.

[0015] When the cold-rolled sheet body is placed on the support frame, the rotating torsion wheel drives the bidirectional lead screw to rotate on the positioning seat. The threaded part of the splash guard drives the two splash guards on both sides to move in opposite directions along the limiting rod, adjusting the clamping distance of the cold-rolled sheet body. The guide rod and threaded rod are installed through the fixed seat. The fixed frame and reinforcing frame of the support plate cooperate with the guide rod and threaded rod through the connecting seat. When the threaded rod rotates, it drives the support plate to move axially along the guide rod, realizing the horizontal movement of the spraying component for spraying. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This embodiment provides a cold-rolled thin sheet anti-oxidation spraying device, such as... Figure 1-3 As shown, the spraying device includes a support frame 1 and several legs 2 equidistantly installed at the bottom of the support frame 1. A spraying assembly is provided at the upper end of the support frame 1, and a cold-rolled sheet body 3 is provided at the upper end of the support frame 1.

[0023] The spraying assembly includes a material tank 4 mounted on a support plate 5. A pump body 6 connected to the material tank 4 is mounted on the lower end of the support plate 5. A guide pipe 41 is mounted on the back of the material tank 4. A discharge pipe 61 is mounted on the side of the pump body 6 via a clamp seat. The outlet of the guide pipe 41 is connected to the inlet of the discharge pipe 61.

[0024] An adjustment mechanism is provided on the support frame 1;

[0025] The adjustment mechanism includes fixed seats 11 symmetrically mounted on the support frame 1. A guide rod 67 is fixedly mounted on the fixed seat 11 on one side of the support frame 1, and a threaded rod 68 is rotatably connected to the fixed seat 11 on the other side of the support frame 1. Fixed frames 64 are symmetrically mounted on the support plate 5. Each fixed frame 64 is fixedly mounted with a reinforcing frame 65. A connecting seat 66 for fitting with the threaded rod 68 and the guide rod 67 is fixedly mounted on the reinforcing frame 65.

[0026] Specifically, the support frame 1 provides stable support through the legs 2, and the cold-rolled sheet body 3 is placed on the upper end of the support frame to be sprayed; in the spraying assembly, the material tank 4 stores the anti-oxidation coating, and the pump body 6 pumps the coating through the guide pipe 41 to the discharge pipe 61. The adjustment mechanism is equipped with the guide rod 67 and the threaded rod 68 through the fixed seat 11. The fixed frame 64 and the reinforcing frame 65 of the support plate 5 cooperate with the guide rod 67 and the threaded rod 68 through the connecting seat 66. When the threaded rod 68 rotates, it drives the support plate 5 to move axially along the guide rod 67. The horizontal movement of the spraying assembly enables spraying. The fixed base 11 is made of cast iron and welded to the support frame 1 to ensure the stable installation of the guide rod 67 and threaded rod 68. The reinforcing frame 65 is a triangular rib plate structure, which improves the connection strength between the fixed frame 64 and the connecting base 66, ensuring that the spraying assembly moves without shaking. The gap between the connecting base 66 and the guide rod 67 is ≤0.1mm, allowing for smooth sliding. There are 4 support legs 2 with a height of 80cm. The material tank 4 has a volume of 50L, which can meet the single spraying volume of cold-rolled thin plates with a length of 2-3m.

[0027] A material distribution plate 62 is fixedly installed at the outlet of the discharge pipe 61, and several nozzles 63 are evenly distributed at the lower end of the material distribution plate 62.

[0028] More specifically, the coating conveyed by the discharge pipe 61 enters the distribution plate 62, and after being distributed by the internal equal resistance flow channel, it is evenly sprayed out from the equally spaced nozzles 63 to cover the surface of the cold-rolled sheet body 3. The equal resistance design of the internal flow channel of the distribution plate 62 ensures that the coating flow deviation of each nozzle 63 is ≤5%. There are 4 nozzles 63, which are adapted to the width of common cold-rolled sheets. The nozzles 63 are fan-shaped atomizing nozzles 63.

[0029] The connecting seat 66 at the end away from the guide rod 67 is threadedly fitted with the threaded rod 68. The fixed seat 11 on the side close to the threaded rod 68 is equipped with a servo motor 69, and the output end of the servo motor 69 is fixedly connected to one end of the threaded rod 68.

[0030] Furthermore, the servo motor 69 starts to drive the threaded rod 68 to rotate, and the connecting seat 66, which is threadedly sleeved with the threaded rod 68, drives the support plate 5 to move axially along the guide rod 67, so as to realize the horizontal reciprocating or unidirectional moving spraying of the spraying assembly.

[0031] The upper end of the support frame 1 is symmetrically provided with anti-splash plates 74 for clamping the cold-rolled sheet body 3. The anti-splash plates 74 are composed of vertical plates and inclined plates.

[0032] It should be noted that the splash guard 74 is composed of a vertical plate and an inclined plate, symmetrically arranged on the upper end of the support frame 1, forming a clamp on both sides of the cold-rolled sheet body 3, while blocking paint splashes during spraying and keeping the working environment clean. The vertical plate of the splash guard 74 is 5cm high and the inclined plate is at a 45° angle to the horizontal, effectively blocking more than 90% of splashed paint. It is made of stainless steel, which is resistant to paint corrosion. When clamped, the gap between it and the side of the cold-rolled sheet is ≤2mm, which neither damages the sheet nor restricts its displacement.

[0033] Both ends of the support frame 1 are provided with positioning seats 7. A bidirectional screw 71 is rotatably connected to the positioning seats 7 distributed opposite to each other at one end of the support frame 1. The splash plate 74 is threaded onto the end of the bidirectional screw 71 near it. One end of the bidirectional screw 71 passes through the positioning seat 7, and a torsion wheel 72 is fixedly installed at the passage.

[0034] It is worth mentioning that rotating the torsion wheel 72 drives the bidirectional lead screw 71 to rotate on the positioning seat 7. Since the threads at both ends of the bidirectional lead screw 71 rotate in opposite directions, the part that is threaded onto the splash guard 74 drives the two splash guards 74 to move in opposite directions along the limiting rod 73, adjusting the clamping distance on the cold-rolled sheet body 3 to adapt to sheets of different widths.

[0035] A limiting rod 73 is fixedly connected to a positioning seat 7 at the other end of the support frame 1, and a splash guard 74 is movably sleeved on the end of the limiting rod 73 near the limiting rod 73.

[0036] The limiting rod 73 is fixed to the positioning seat 7 to provide guidance for the movement of the splash guard 74. One end of the splash guard 74 is threadedly engaged with the bidirectional lead screw 71, and the other end is movably sleeved with the limiting rod 73 to ensure that the splash guard 74 moves in a straight line and avoids deviation.

[0037] In use, when the cold-rolled sheet body 3 is placed on the support frame 1, the rotating torsion wheel 72 drives the bidirectional lead screw 71 to rotate on the positioning seat 7. The threaded part of the splash guard 74 drives the two splash guards 74 to move in opposite directions along the limiting rod 73, adjusting the clamping distance of the cold-rolled sheet body 3. The guide rod 67 and the threaded rod 68 are installed through the fixing seat 11. The fixing frame 64 and the reinforcing frame 65 of the support plate 5 cooperate with the guide rod 67 and the threaded rod 68 through the connecting seat 66. When the threaded rod 68 rotates, it drives the support plate 5 to move axially along the guide rod 67, realizing the horizontal movement of the spraying assembly for spraying.

[0038] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
