Description

Technical Field

[0001] This invention relates to the field of quantitative feeding devices, specifically a quantitative feeding device for chromium-free passivating agent processing. Background Technology

[0002] With the continuous development of the metal surface treatment industry, chromium-free passivating agents have been widely used due to their advantages such as being environmentally friendly, pollution-free, and having excellent passivation effects. In the large-scale production and processing of chromium-free passivating agents, the quantitative feeding process is a key link in controlling the raw material ratio and ensuring the quality of the finished product. Therefore, a special feeding device is needed to complete the automated and precise feeding operation.

[0003] However, in actual use, most of the existing quantitative feeding devices are equipped with cleaning structures that can only perform single-direction rotation cleaning, making it difficult to achieve a combined cleaning action that combines revolution and rotation. This is not conducive to removing stubborn dried raw materials and various adhesive stains from the surface of the equipment, resulting in low cleaning efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a quantitative feeding device for chromium-free passivating agent processing. By setting up a rotating cleaning section, it solves the problem that in the actual use of existing quantitative feeding devices, the matching cleaning structure can only perform single-direction rotation cleaning, making it difficult to achieve a composite cleaning action that combines revolution and rotation, which is not conducive to removing stubborn dried raw materials and various adhesive stains attached to the surface of the equipment, resulting in low cleaning efficiency.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a quantitative feeding device for chromium-free passivating agent processing, comprising a chassis, and further comprising: a feeding section disposed on the chassis; a rotating cleaning section disposed above the chassis; two quick-change sections, the two quick-change sections being mirror-mounted above the chassis; the rotating cleaning section comprising a rotating assembly disposed above the chassis; and a driving assembly disposed above the chassis; the rotating assembly comprising a circular box disposed above the chassis, the inner wall of the circular box being fixedly connected to a gear ring, a rotating shaft being disposed on the circular box, the outer wall of the rotating shaft being fixedly connected to a gear, the gear meshing with the gear ring, and a rotating connection being fixedly connected to the rotating shaft. The rod has an mounting block fixedly connected to the outer wall of the rotating shaft, and a disc is rotatably connected to the inner wall of the circular box. The rotating shaft rotates through the disc. The rotating component is the core motion execution structure for the equipment cleaning operation. Relying on the meshing of the circular box, gear ring, and gear, and in conjunction with the linkage structure of the disc, rotating shaft, and connecting rod, it cleverly realizes the composite motion mode of the cleaning block's revolution and rotation. Unlike a single rotation cleaning structure, this composite motion mode can reduce the cleaning dead corners of the feeding area and equipment surface, and can efficiently clean the residual agent residue, dust, and accumulated material after the chromium-free passivating agent feeding operation. It avoids the residual passivating agent from solidifying and agglomerating, affecting the subsequent quantitative feeding accuracy, while ensuring the cleanliness of the equipment feeding area, and effectively improving the stability of passivating agent processing and production and product quality.

[0006] Furthermore, the drive assembly includes a motor fixedly connected to the top of the circular box. The output shaft of the motor is fixedly connected to a second rotating shaft via a coupling. The bottom of the second rotating shaft extends rotatably into the circular box. A connecting rod is passed through the second rotating shaft and fixedly connected thereto. The second rotating shaft and the circular box are coaxially arranged. The drive assembly provides stable and continuous power output for all cleaning movements of the rotating assembly. It is the core power source for achieving automated rotating cleaning. Through the fixed connection structure of the motor, the second rotating shaft, and the connecting rod, the rotating assembly can be driven to operate smoothly as a whole, providing sufficient power for the combined revolution and rotation of the cleaning block, ensuring efficient cleaning operations, replacing traditional manual cleaning methods, significantly improving the automation level of equipment cleaning, reducing manual maintenance costs, and adapting to the production operation requirements of continuous quantitative feeding of equipment.

[0007] Furthermore, the feeding unit includes a feeding bin installed on the inner wall of the machine casing, a discharge pipe connected to the bottom of the feeding bin, an electric valve installed on the outer wall of the discharge pipe, and an observation window provided on the front side of the machine casing; the discharge pipe extends to the outside of the machine casing and is fixedly connected to the machine casing, and scale lines are provided on the outer wall of the feeding bin.

[0008] Furthermore, the quick-change part includes a snap-fit ​​assembly disposed on the mounting block; and a sliding assembly mounted on the mounting block. The snap-fit ​​assembly includes a cylindrical groove formed on the mounting block, a cylindrical shell fixedly connected to the inner wall of the cylindrical groove, a locking rod slidably connected to the cylindrical shell, the locking rod slidably connected to the cylindrical shell, a circular block fixedly connected to the outer wall of the locking rod, the outer wall of the circular block slidably connected to the inner wall of the cylindrical shell, two spring dampers fixedly connected to the front side of the circular block, the front sides of the two spring dampers fixedly connected to the inner wall of the cylindrical shell, and a handle fixedly connected to the front side of the locking rod. The core locking structure of the hand-operated buckle assembly enables quick assembly and disassembly of the cleaning block. Relying on the elastic linkage structure of the cylindrical shell, spring damper, circular block, and locking rod, it constructs a limit fixing mechanism with elastic locking and manual unlocking. Under normal conditions, it can stably lock the sliding component in the slot, preventing the cleaning block from loosening, shifting, or falling off during high-speed rotation cleaning operations, ensuring the safety and stability of the cleaning operation. When it is necessary to replace the cleaning parts, simply pull the handle manually to quickly release the limit. The operation is convenient and the locking is firm, effectively solving the drawbacks of traditional equipment such as cumbersome assembly and disassembly of cleaning blocks, weak fixation, and time-consuming replacement, greatly improving the efficiency of equipment operation and maintenance.

[0009] Furthermore, the sliding assembly includes a groove formed on the mounting block, a sliding rod provided on the inner wall of the groove, the outer wall of the sliding rod slidingly contacting the inner wall of the groove, a slot formed on the sliding rod, and a cleaning block fixedly connected to the sliding rod; the rear side of the locking rod slides into the groove, the outer wall of the locking rod slidingly contacting the inner wall of the slot. The sliding assembly provides guidance and installation carrier for the disassembly and sliding of the cleaning block, and is a key load-bearing structure adapted to the quick replacement structure. Through the sliding cooperation of the groove and the sliding rod, the cleaning block can be disassembled and installed by pulling, the sliding process is smooth and the positioning is stable, and the alignment and installation of new and old cleaning blocks can be completed quickly; at the same time, with the slot limiting structure of the buckle assembly, the cleaning block is accurately fixed, ensuring that the cleaning block is installed in a precise position and the force is even, which not only meets the need for quick replacement of the cleaning block after wear and dirt, but also ensures the installation stability of the cleaning block during operation, ensuring the uniformity and effectiveness of the rotary cleaning operation, and adapting to the long-term high-frequency cleaning operation conditions of the equipment.

[0010] Furthermore, the lifting unit includes a support block fixedly connected to the rear side of the chassis. Two cylindrical slide rods are fixedly connected to the top of the support block, and sliders are slidably connected to the outer walls of the two cylindrical slide rods. A power component is provided on the support block. The front side of the slider is fixedly connected to the outer wall of the circular box. The power component includes an electric telescopic rod fixedly connected to the top of the support block, and the output shaft of the electric telescopic rod is fixedly connected to the bottom of the slider.

[0011] The present invention has the following beneficial effects: This invention features a rotating cleaning unit powered by a drive assembly. The combined rotation and revolution of the cleaning structure, achieved through gear and ring meshing, allows for comprehensive cleaning of the feeding equipment and surrounding areas without blind spots. It effectively removes residues and stains from chromium-free passivating agents. The combined motion increases the frequency of friction between the cleaning block and the contact surface. The rotation adjusts the contact angle of the cleaning surface, while the revolution extends the cleaning stroke. Stubbornly dried materials and adhered stains can be quickly removed, significantly improving cleaning efficiency and reducing the need for manual secondary cleaning. (2) By setting up a quick replacement part, the invention uses a spring damper in conjunction with a locking rod to achieve quick locking and loosening, and uses a sliding groove and sliding rod to complete the pulling and disassembly of the cleaning block. The cleaning block can be quickly disassembled and installed without the need for special tools, which greatly shortens the time spent on replacing cleaning parts, improves equipment operation and maintenance efficiency, and further improves cleaning efficiency. (3) By setting up a lifting part, the present invention uses an electric telescopic rod as a power source to drive the slider to slide smoothly vertically along the cylindrical slide rod, thereby driving the overall rotating cleaning structure to complete the height adjustment, which can adjust the vertical working range of the cleaning operation and adapt to the cleaning operation needs of different height feeding stations of the feeding container.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-8 As shown, the present invention is a quantitative feeding device for chromium-free passivating agent processing, including a housing 111, and further including: a feeding section 1, which is disposed on the housing 111; a rotating cleaning section 2, which is disposed above the housing 111; and two quick-change sections 3, which are mirror images of each other and mounted above the housing 111. The feeding section 1 includes a feeding bin 112 installed on the inner wall of the housing 111. The bottom of the feeding bin 112 is connected to a discharge pipe 113.

The rotating shaft 222 and the circular box 211 are coaxial. By setting the rotating cleaning part 2, the superimposed compound motion will increase the frequency of friction contact between the cleaning block 324 and the contact surface. The rotation can adjust the contact angle of the cleaning surface, and the revolution can expand the cleaning stroke. Stubborn dried materials and adhered stains can be quickly peeled off, greatly improving cleaning efficiency and reducing manual secondary cleaning.

[0019] The quick-change unit 3 includes a snap-fit ​​assembly 31, which is mounted on the mounting block 216; and a sliding assembly 32, which is also mounted on the mounting block 216. The snap-fit ​​assembly 31 includes a cylindrical groove 311 formed in the mounting block 216. A cylindrical shell 312 is fixedly connected to the inner wall of the cylindrical groove 311. A locking rod 313 is slidably connected to the cylindrical shell 312. A circular block 314 is fixedly connected to the outer wall of the locking rod 313. The outer wall of the circular block 314 is slidably connected to the inner wall of the cylindrical shell 312. Two spring dampers 315 are fixedly connected to the front side of the circular block 314. The front sides of the two spring dampers 315 are fixed to the inner wall of the cylindrical shell 312. The connection includes a handle 316 fixedly connected to the front side of the lever 313, and a sliding assembly 32 including a groove 321 formed on the mounting block 216. A sliding rod 322 is provided on the inner wall of the groove 321, and the outer wall of the sliding rod 322 slides in contact with the inner wall of the groove 321. A slot 323 is formed on the sliding rod 322, and a cleaning block 324 is fixedly connected to the sliding rod 322. The rear side of the lever 313 slides into the groove 321, and the outer wall of the lever 313 slides in contact with the inner wall of the slot 323. By setting up a quick replacement part 3, the cleaning block 324 can be quickly disassembled and installed without the need for special tools, which greatly shortens the time for replacing cleaning parts, improves equipment operation and maintenance efficiency, and further enhances the cleaning effect.

[0020] The lifting unit 4 includes a support block 411 fixedly connected to the rear side of the housing 111. Two cylindrical slide rods 412 are fixedly connected to the top of the support block 411. A slider 413 is slidably connected to the outer wall of the two cylindrical slide rods 412. A power component is provided on the support block 411. The front side of the slider 413 is fixedly connected to the outer wall of the circular box 211. The power component includes an electric telescopic rod 414 fixedly connected to the top of the support block 411. The output shaft of the electric telescopic rod 414 is fixedly connected to the bottom of the slider 413. By setting the lifting unit 4, the vertical working range of the cleaning operation can be adjusted, which can adapt to the cleaning operation needs of different height feeding positions of the feeding container.

[0021] During use, a quantitative amount of chromium-free passivating agent processing raw material is added into the feeding bin 112 by observing the scale on the outer wall of the feeding bin 112, and the electric valve 114 on the discharge pipe 113 is controlled to open and close the electric valve 114 on the discharge pipe 113 to realize the quantitative discharge of passivating agent raw material and complete the quantitative feeding operation. The support block 411 of the lifting part 4 is fixed to the rear side of the housing 111 as the base of the lifting structure. The output shaft of the electric telescopic rod 414 extends and retracts, driving the slider 413 to slide vertically up and down along the two cylindrical slide rods 412. The slider 413 simultaneously drives the circular box 211 to lift and lower as a whole, thereby adjusting the working height of the rotating cleaning part 2 to adapt to different material feeding conditions and cleaning needs. During cleaning, the motor 221 of the drive assembly 22 starts, driving the connecting rod 215 to rotate synchronously through the second rotating shaft 222. The second rotating shaft 222 drives the first rotating shaft 213 to rotate through the disc 217, causing the gear 214 to mesh and rotate along the gear ring 212 on the inner wall of the circular box 211. The first rotating shaft 213 synchronously drives the mounting block 216 and the gear 214 to make circumferential motion. Since the gear 214 meshes with the gear ring 212, the gear 214 will drive the first rotating shaft 213 to rotate, thereby causing the mounting block 216 to rotate while making circumferential motion. The cleaning block 324 mounted on the mounting block 216 moves with it, rotating and cleaning the equipment and the feeding area. When the cleaning block 324 needs to be replaced, the lifting unit 4 is controlled to raise the rotating cleaning unit 2 to its highest point. The handle 316 is pulled to move the locking rod 313, causing the circular block 314 to press against the spring damper 315 inside the cylindrical shell 312. The locking rod 313 then exits from the slot 323 of the slide rod 322, releasing the limit. The slide rod 322 is then slid down along the slide groove 321 of the mounting block 216 and pulled out, allowing the old cleaning block 324 to be removed. After inserting the slide rod 322 corresponding to the new cleaning block 324, the handle 316 is released, and the spring damper 315 springs back to its original position, pushing the circular block 314 and the locking rod 313 into the slot 323, completing the quick and easy replacement of the cleaning block 324. The quick replacement units 3, which are mirrored on both sides, can complete the replacement operation simultaneously or independently.

[0022] It should be noted that the control of the electric valve 114, motor 221 and electric telescopic rod 414 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be set using existing technologies, such as PLC.
