Description

Technical Field

[0001] This invention relates to the field of blackening treatment technology, specifically a blackening treatment process for chain processing. Background Technology

[0002] As a crucial mechanical transmission component, the rust prevention treatment of chains is a key step in extending their service life, and blackening is a widely used surface treatment process. Currently, traditional chain blackening treatment often employs a batch immersion method, placing the chains in a blackening solution for a certain period before removing them. This method has significant drawbacks: First, chains tend to accumulate in the basket, preventing the blackening solution from fully and evenly contacting all chain links, especially overlapping and tightly adhering surfaces, easily creating processing dead zones and affecting the uniformity and density of the blackening film. Second, the entire process requires multiple manual lifting and transfers, resulting in low automation, low production efficiency, and high labor intensity. Furthermore, a large amount of blackening solution carried on the chain surface during discharge cannot be effectively recovered, not only wasting chemical raw materials but also increasing the burden on subsequent cleaning and wastewater treatment. Therefore, there is an urgent need for a new chain blackening treatment process and device that can achieve automated continuous production, ensure processing uniformity, and improve the utilization rate of the chemical solution. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a chain processing blackening process that solves the aforementioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a chain processing blackening process, comprising the following steps: S1: Loading: The chain to be processed is loaded into the basket of the blackening equipment at the loading station; S2: Immersion and dynamic treatment. By intermittently rotating the turntable, the basket containing the chain is immersed in the blackening treatment liquid in the blackening box. At the same time, the actuating mechanism is activated to turn the chain in the basket, and the liquid jetting system is activated to spray the blackening treatment liquid onto the chain. S3: Draining. The basket that has been soaked is lifted off the liquid surface by the turntable, allowing the excess blackening treatment liquid on the chain surface to drain naturally and flow back to the blackening box. S4: Automatic unloading. After being drained, the basket moves to the unloading station. Through the cooperation of the support mechanism and the bottom structure of the basket, the bottom plate of the basket is automatically opened, allowing the processed chain to fall into the discharge conveyor belt. S5: Discharge. The discharge conveyor belt receives the chain and transports it out of the black box, completing the final draining of the chain surface during the conveying process.

[0005] As a further aspect of the present invention: the actuating mechanism in step S2 is driven by a drive gear to drive a gear ring, which in turn drives the actuating rod fixed to the bottom of the gear ring to rotate in the inner cavity of the basket to achieve flipping.

[0006] As a further aspect of the present invention: the liquid jetting system in step S2 consists of a pump and a purging bucket. The inlet of the pump is connected to the inner cavity of the blackening box, and the outlet is connected to the purging bucket through a pipe. The outlet of the purging bucket is directly opposite the basket in the immersion position.

[0007] As a further aspect of the present invention: the automatic unloading in step S4 is specifically as follows: when the basket moves to the unloading position, the collar fixed to the bottom of the basket slides along the inclined support ring surface, causing the basket to tilt. At the same time, the hydraulic rod is activated, driving the bent section hinged to the support ring to rotate downwards. The collar then loses its support, and the bottom plate of the basket automatically opens under the action of gravity to complete the unloading.

[0008] As a further aspect of the present invention: the blackening equipment includes a blackening box and a support plate fixed to the side of the blackening box. A rotating shaft driven by a motor is rotatably connected to the bottom of the support plate. One end of the rotating shaft is fixedly connected to a turntable inclined at 45 degrees clockwise. Multiple connecting rods are fixedly connected to the bottom of the turntable. A hanging basket with perforated surface is fixedly connected to the bottom end of each connecting rod. A base plate is rotatably connected to the bottom right side of the hanging basket. The inner cavity of the blackening box is filled with blackening treatment liquid. When the turntable is in its initial position, the rightmost hanging basket is completely submerged in the blackening treatment liquid cavity, while the middle hanging basket is located... Above the blackening treatment liquid, a support mechanism is fixedly connected to the bottom of the inner cavity of the blackening box. The support mechanism includes a support ring fixed in the inner cavity of the blackening box and inclined upward on the left side. A collar that is slidably connected to the surface of the support ring is fixedly connected to the left side of the bottom plate. A bending section is rotatably connected to the left side of the support ring. A hydraulic rod is rotatably connected to the inner cavity of the blackening box. The output end of the hydraulic rod is hinged to the bottom of the bending section. The inner cavity of the blackening box is provided with a discharge conveyor belt located below the bending section and above the surface of the blackening treatment liquid. A discharge port adapted to the discharge conveyor belt is opened on the left side of the blackening box.

[0009] As a further aspect of the present invention: a toothed ring is rotatably connected to the surface of the connecting rod, and a toggle rod located in the inner cavity of the basket is fixedly connected to the bottom of the toothed ring. A drive gear driven by a motor is rotatably connected to the inner cavity of the blackening box. When the basket moves to the lowest position, its corresponding toothed ring meshes with the drive gear.

[0010] As a further aspect of the present invention: a pump is fixedly connected to the inner cavity of the blackening box, the inlet of the pump is connected to the inner cavity of the blackening box, and its outlet is connected to a purging bucket, with the outlet of the purging bucket facing the lowest position of the basket.

[0011] Compared with the prior art, the present invention has the following advantages: The automated continuous production of chain blackening treatment has been realized. The rotating shaft driven by the motor drives the turntable to rotate intermittently, so that multiple baskets go through the loading, soaking, draining and unloading processes in sequence, which greatly improves production efficiency and reduces labor costs and labor intensity.

[0012] This effectively ensures the uniformity of the blackening process. On one hand, the chain is turned over by a lever installed inside the basket, driven by the drive gear, breaking up the chain's accumulation and ensuring that all surfaces can fully contact the blackening solution. On the other hand, the pump and sling spray the blackening solution onto the immersed chain, creating impact and turbulence, further preventing the formation of dead zones in the process.

[0013] This design significantly improves the utilization rate of the blackening solution and enhances the working environment. The basket features a draining process after leaving the liquid surface, allowing excess solution to drip back into the blackening box. Simultaneously, the cooperation between the support mechanism and the collar enables controllable opening of the basket's bottom plate, allowing the chain to fall cleanly onto the discharge conveyor belt, reducing solution carry-over loss. The discharge conveyor belt also effectively drains any residual solution droplets from the chain before discharging, saving raw materials and reducing pollution. Attached Figure Description

[0017] Please see Figure 1-4 This invention provides a technical solution: a chain processing blackening process, comprising the following steps: S1: Loading: The chain to be processed is loaded into the basket 7 of the blackening equipment at the loading station. S2: Immersion and dynamic treatment: By intermittently rotating the turntable 5, the basket 7 containing the chain is immersed in the blackening treatment liquid of the blackening box 1. At the same time, the actuation mechanism is activated to turn the chain in the basket 7, and the liquid jetting system is activated to spray the blackening treatment liquid onto the chain. S3: Draining, the basket 7 that has completed the soaking is lifted by the turntable 5 and leaves the liquid surface, allowing the excess blackening treatment liquid on the chain surface to drain naturally and flow back to the blackening box 1. S4: Automatic unloading. After being drained, the basket 7 moves to the unloading station. Through the cooperation of the support mechanism and the bottom structure of the basket 7, the bottom plate 8 of the basket 7 is automatically opened, allowing the processed chain to fall into the discharge conveyor belt 2. S5: Discharge. The discharge conveyor belt 2 receives the chain and transports it out of the black box 1, completing the final drying of the chain surface during the conveying process.

[0018] In step S2, the actuating mechanism is driven by the drive gear 12 to drive the gear ring 11, which in turn drives the actuating rod 18 fixed at the bottom of the gear ring 11 to rotate in the inner cavity of the basket 7 to achieve flipping.

[0019] The liquid jetting system in step S2 consists of a pump 13 and a purge bucket 14.

The outlet of the purge bucket 14 is directly opposite the basket 7 in the immersion position.

[0020] The automatic unloading in step S4 is as follows: when the basket 7 moves to the unloading position, the collar 9 fixed to the bottom of the basket 7 slides along the surface of the inclined support ring 15, causing the basket 7 to tilt. At the same time, the hydraulic rod 17 is activated, driving the bent section 16 hinged to the support ring 15 to rotate downward.

[0023] A pumping pump 13 is fixedly connected to the inner cavity of the blackening box 1. The inlet of the pumping pump 13 is connected to the inner cavity of the blackening box 1, and its outlet is connected to a purging bucket 14. The outlet of the purging bucket 14 faces the basket 7 at the lowest position.

[0024] The blackening equipment includes a blackening box 1 and a support plate 3 fixed to the side of the blackening box 1. A rotating shaft 4 driven by a motor is rotatably connected to the bottom of the support plate 3. A turntable 5 is fixedly connected to one end of the rotating shaft 4. The turntable 5 is tilted clockwise at 45 degrees. Multiple connecting rods 6 are fixedly connected to the bottom of the turntable 5. A hanging basket 7 is fixedly connected to the bottom end of each connecting rod 6. The surface of the hanging basket 7 has mesh openings. A base plate 8 is rotatably connected to the bottom right side of the hanging basket 7. The inner cavity of the blackening box 1 is filled with blackening treatment liquid. When the turntable 5 is in its initial position, the rightmost hanging basket 7 is completely submerged in the blackening treatment liquid cavity, and the middle hanging basket 7 is located above the blackening treatment liquid. A support mechanism is fixedly connected to the bottom of the inner cavity of the blackening box 1. The support mechanism includes a support ring 15 fixed to the inner cavity of the blackening box 1. The support ring 15 is tilted upwards on the left side of the inner cavity of the blackening box 1. The left side of the base plate 8 is fixedly connected to... A collar 9 is slidably connected to the surface of a support ring 15. A bent section 16 is rotatably connected to the left side of the support ring 15. A hydraulic rod 17 is rotatably connected to the inner cavity of the blackening box 1. The output end of the hydraulic rod 17 is hinged to the bottom of the bent section 16. A discharge conveyor belt 2 is provided in the inner cavity of the blackening box 1, located below the bent section 16 and above the surface of the blackening treatment liquid. A discharge port adapted to the discharge conveyor belt 2 is opened on the left side of the blackening box 1. A toothed ring 11 is rotatably connected to the surface of a connecting rod 6. A toggle rod 18 located in the inner cavity of the basket 7 is fixedly connected to the bottom of the toothed ring 11. A drive gear 12 driven by a motor is rotatably connected to the inner cavity of the blackening box 1. When the basket 7 moves to the lowest position, it meshes with the drive gear 12. A pumping pump 13 connected to the blackening liquid source is fixedly connected to the inner cavity of the blackening box 1. The discharge port of the pumping pump 13 is connected to a blower hopper 14 with its outlet facing the lowest position basket 7.

[0025] In use, the operator loads the chains to be treated into the uppermost basket 7. After starting the equipment, the motor drives the rotating shaft 4 to rotate intermittently, causing the turntable 5 and multiple connecting rods 6 fixed thereon and the baskets 7 to move forward sequentially. When a basket 7 moves to its lowest position, it is completely immersed in the blackening treatment liquid in the blackening box 1. At this time, the toothed ring 11 corresponding to the basket 7 meshes with the drive gear 12 inside the blackening box 1. The motor drives the drive gear 12 to rotate, which in turn drives the toothed ring 11 and the actuating rod 18 fixed at its bottom to rotate inside the basket 7. The actuating rod 18 agitates and stirs the accumulated chains, ensuring that all surfaces of the chains are in full contact with the blackening liquid. At the same time, the pump 13 draws the blackening liquid from the box and sprays it into the basket 7 through the blower 14, forming a dynamic liquid flow and enhancing the treatment effect. After impregnation, turntable 5 rotates, and the basket 7 rises and leaves the liquid surface. Excess liquid carried by the chain drains back into the box through the mesh of the basket 7. When the basket 7 rotates to the discharge position, the collar 9 at the bottom of the basket 7 slides along the surface of the upwardly inclined support ring 15, forcing the basket 7 to tilt to the left. At this time, the hydraulic rod 17 retracts, pulling the bent section 16 downward to rotate. The unsupported collar 9 causes the bottom plate 8 of the basket 7 to open around the axis under the action of gravity, and the chain that has completed the blackening treatment falls onto the discharge conveyor belt 2 below. The discharge conveyor belt 2 transports the chain to the discharge port on the left side of the blackening box 1. During this process, the residual droplets on the chain surface are further drained, finally completing the entire blackening treatment process.
