Description

Technical Field

[0001] This utility model belongs to the field of metal surface treatment technology, specifically a blackening treatment device for metal surface protection. Background Technology

[0002] Blackening is a common method of chemical surface treatment. The principle is to create an oxide film on the metal surface to isolate it from the air and achieve rust prevention. In related technologies, when blackening metal parts, the metal parts are placed in a box containing a blackening agent. By immersing the metal parts in the blackening agent, the blackening process is achieved through the contact between the outer surface of the metal parts and the blackening agent.

[0003] However, due to temperature changes and prolonged use and storage, substances inside the blackening agent may deposit, thus affecting the subsequent blackening effect on metal surfaces. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a blackening treatment device for metal surface protection, which solves the problem that the blackening agent will deposit substances inside the blackening agent due to temperature changes and after long-term use and storage, thereby affecting the subsequent blackening effect of metal surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blackening treatment device for metal surface protection, comprising a box, support blocks connected to the four corners of the box, a drain pipe connected to one side of the box, a thermometer installed on the box, a heating tube installed inside the box, a fixed base connected to one side of the box, a fixed block connected to the other side of the box, and a fixed cylinder connected to the fixed block;

[0006] The fixed cylinder has a first material inlet, a rotating rod is installed through one side of the fixed cylinder, a first bevel gear is connected to the rotating rod, a secondary synchronous wheel is connected to one end of the rotating rod, a connecting sleeve is rotatably connected to the rotating rod, a rolling cylinder is connected to the other end of the rotating rod, a second bevel gear is connected to the connecting sleeve, and stirring plates are connected to both sides of the connecting sleeve.

[0007] As a further embodiment of this utility model: the rolling cylinder is provided with a second material inlet, and the second material inlet is provided with inclined surfaces on both sides. The rolling cylinder is rotatably disposed inside the fixed cylinder and is in close contact with the inner wall of the fixed cylinder. The opening height of the second material inlet is lower than that of the first material inlet. Both the fixed cylinder and the rolling cylinder are provided with multiple holes.

[0008] As a further embodiment of this utility model: a gear box is fixedly connected to one side of the housing, and a third bevel gear is rotatably connected inside the gear box. The first bevel gear and the second bevel gear are arranged on both sides of the third bevel gear, and both the first bevel gear and the second bevel gear mesh with the third bevel gear.

[0009] As a further embodiment of this utility model: a motor is fixedly installed on the fixed base, a main synchronous pulley is connected to the output shaft of the motor, a toothed synchronous belt is installed on the main synchronous pulley, and the main synchronous pulley is connected to the auxiliary synchronous pulley through the toothed synchronous belt.

[0010] As a further embodiment of this utility model: the connecting sleeve is rotatably connected to one side of the box body, the two stirring plates on the connecting sleeve are U-shaped in shape, and the fixing cylinder is disposed between the two stirring plates.

[0011] As a further embodiment of this utility model: one end of the rotating rod passes through the connecting sleeve, the second bevel gear, and the housing, and an anti-slip rubber pad is provided below the support block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This blackening treatment device for metal surface protection, by setting up a heating tube, a thermometer, a first bevel gear, a second bevel gear, a third bevel gear, a connecting sleeve, and a stirring plate, when the motor drives the rotating rod to rotate, the rotating rod will drive the connecting sleeve to rotate through the meshing of the first bevel gear, the second bevel gear, and the third bevel gear, thereby causing the stirring plate to stir the blackening agent in the box, preventing the blackening agent from settling due to prolonged static storage, while the thermometer can detect the temperature of the blackening agent in real time. When the temperature drops, the heating tube can heat the blackening agent to prevent crystal precipitation caused by temperature drop, thereby ensuring uniform concentration of the treatment agent and ensuring normal blackening treatment effect.

[0014] 2. This blackening treatment device for metal surface protection consists of a motor, a main synchronous pulley, a secondary synchronous pulley, a toothed synchronous belt, a rotating rod, a fixed cylinder, and a rolling drum. The operator starts the motor to rotate the main synchronous pulley. The main synchronous pulley, toothed synchronous belt, and secondary synchronous pulley work together to drive the rotating rod, causing the rolling drum to rotate within the fixed cylinder. This causes the metal parts to roll within the rolling drum. As the rolling drum rolls, the metal parts fall from the second feed port into the fixed cylinder. The rotating rolling drum then uses the inclined surface of the second feed port to scoop up the metal parts again, ensuring continuous rolling and uniform contact between the metal parts and the blackening agent, thus improving the treatment effect.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a blackening treatment device for metal surface protection, including a box 1, support blocks 2 connected to the four corners of the box 1, a drain pipe 3 connected to one side of the box 1, a thermometer 4 installed on the box 1, a heating tube 5 installed inside the box 1, a fixed base 6 connected to one side of the box 1, a motor 20 fixedly installed on the fixed base 6, a main synchronous pulley 21 connected to the output shaft of the motor 20, a toothed synchronous belt 22 installed on the main synchronous pulley 21, the main synchronous pulley 21 being connected to the auxiliary synchronous pulley 12 via the toothed synchronous belt 22, and through the cooperation between the main synchronous pulley 21, the toothed synchronous belt 22 and the auxiliary synchronous pulley 12, the motor 20 can drive the rolling drum 14 to rotate, thereby causing the metal parts to roll continuously, promoting uniform contact between all surfaces of the metal parts and the blackening treatment agent.

[0022] A fixing block 7 is connected to the other side of the housing 1. A fixing cylinder 8 is connected to the fixing block 7. A first material inlet 9 is opened on the fixing cylinder 8. A rotating rod 10 is installed through one side of the fixing cylinder 8. One end of the rotating rod 10 passes through the connecting sleeve 13, the second bevel gear 15 and the housing 1. An anti-slip rubber pad is installed below the support block 2. The rotating rod 10 passes through the connecting sleeve 13 and the second bevel gear 15. With the cooperation between the first bevel gear 11, the second bevel gear 15 and the third bevel gear 19, the connecting sleeve 13 and the second bevel gear 15 can rotate on the rotating rod 10. The anti-slip rubber pad below the support block 2 can increase friction, thereby preventing the housing 1 from sliding accidentally.

[0023] A first bevel gear 11 is connected to the rotating rod 10. A gear box 18 is fixedly connected to one side of the housing 1. A third bevel gear 19 is rotatably connected inside the gear box 18. The first bevel gear 11 and the second bevel gear 15 are located on both sides of the third bevel gear 19, and both the first bevel gear 11 and the second bevel gear 15 mesh with the third bevel gear 19. The gear box 18 protects the first bevel gear 11, the second bevel gear 15 and the third bevel gear 19, thereby reducing the corrosion and impact damage to the first bevel gear 11, the second bevel gear 15 and the third bevel gear 19.

[0024] One end of the rotating rod 10 is connected to a secondary synchronous wheel 12, and a connecting sleeve 13 is rotatably connected to the rotating rod 10. The other end of the rotating rod 10 is connected to a rolling cylinder 14. A second material port 17 is opened on the rolling cylinder 14, and inclined surfaces are provided on both sides of the second material port 17. The rolling cylinder 14 is rotatably set inside the fixed cylinder 8 and is in close contact with the inner wall of the fixed cylinder 8. The opening height of the second material port 17 is lower than that of the first material port 9. Multiple holes are opened on both the fixed cylinder 8 and the rolling cylinder 14. Through the inclined surfaces on both sides of the second material port 17, the metal parts that fall out can slide back into the rolling cylinder 14 when the rolling cylinder 14 rotates, so that the metal parts can continuously roll inside the rolling cylinder 14.

[0025] A second bevel gear 15 is connected to the connecting sleeve 13, and stirring plates 16 are connected to both sides of the connecting sleeve 13. The connecting sleeve 13 is rotatably connected to one side of the box body 1. The two stirring plates 16 on the connecting sleeve 13 are U-shaped in design. The fixed cylinder 8 is set between the two stirring plates 16. The blackening agent is stirred by the stirring plates 16 to ensure the flow of the blackening agent and avoid sedimentation caused by long-term standing.

[0026] The working principle of this utility model is as follows:

[0027] The operator starts the motor 20 to rotate the main synchronous pulley 21. The main synchronous pulley 21, toothed synchronous belt 22 and auxiliary synchronous pulley 12 drive the rotating rod 10 to rotate, which causes the rolling drum 14 to rotate in the fixed cylinder 8. This causes the metal parts to roll in the rolling drum 14. As the rolling drum 14 rolls, the metal parts fall from the second feed port 17 into the fixed cylinder 8. The rotating drum 14 then picks up the metal parts again through the inclined surface of the second feed port 17, thus causing the metal parts to continuously roll in the rolling drum 14 and make uniform contact with the blackening agent. When the rotating rod 10 rotates, the rotating rod 10 drives the connecting sleeve 13 to rotate through the meshing of the first bevel gear 11, the second bevel gear 15 and the third bevel gear 19. This causes the stirring plate 16 to stir the blackening agent in the box 1. The thermometer 4 can detect the temperature of the blackening agent in real time. When the temperature drops, the heating tube 5 can heat the blackening agent to prevent crystal precipitation caused by the temperature drop and ensure the uniform concentration of the blackening agent.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
