Description

Technical Field

[0001] This utility model relates to the field of paint delivery technology, specifically to an anti-clogging pressure adaptive adjustment device for paint delivery pipelines. Background Technology

[0002] Traditional paint conveying systems typically use rigid pipes with fixed diameters and mechanical pressure valves for flow control. However, when conveying powder coatings, the powder is prone to moisture absorption and clumping, electrostatic adsorption, and interparticle friction, which often leads to blockages inside the pipes, causing a sudden increase in pressure and severely affecting production continuity. Existing pressure regulating devices mostly use passive mechanical structures or simple solenoid valves, which have problems such as response lag and insufficient regulation accuracy, and cannot adapt to the complex pressure changes required during powder coating conveying.

[0003] In existing technologies, most conveying devices adopt a fixed pipe diameter design, which cannot be dynamically adjusted according to the powder flow state, resulting in large pressure fluctuations and easy blockage. At the same time, powder is prone to agglomeration due to electrostatic adsorption or compression during the conveying process, which increases the pipeline resistance. Conventional vibrators can only provide mechanical vibration at a single frequency, which cannot effectively break up agglomerated powder. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an anti-clogging pressure adaptive adjustment device for paint delivery pipelines, which has the following beneficial effects:

[0017] By incorporating a dynamically adjustable pipe diameter mechanism, the pipe diameter can be adjusted in real time based on pressure sensor feedback, effectively mitigating pressure fluctuations caused by changes in powder flow and preventing localized blockages. Simultaneously, the multi-directional vibration generated by the material shaking mechanism and the differential shearing action of the stirring mechanism efficiently break up electrostatic adsorption and agglomeration of powder. The gear-ring drive structure ensures synchronous movement of multiple adjusting rods, maintaining pipe roundness. Two sets of first spring buffer designs generate a composite vibration frequency in the mounting frame driven by the first cam, significantly improving the dispersion of agglomerated powder. Furthermore, the counter-rotation of the first and second stirring frames through toothed engagement further enhances the uniformity of the shear force field. This device achieves synergistic optimization of adaptive pressure balance and material fluidization control, reducing the risk of blockage compared to a fixed pipe diameter design, and is suitable for the stable conveying of high-solids-content coatings.

Detailed Implementation

[0026] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

An adjustment pipe 3 is provided on the base 1, with both ends of the adjustment pipe 3 fixedly bonded to the two sets of mounting brackets 2. A mounting seat 4 is fixedly mounted on the left mounting bracket 2. A material shaking mechanism 5 is provided on the base 1. Adjustment mechanisms 7 for adjusting the diameter of the adjustment pipe 3 are provided on both sets of mounting brackets 2, and a stirring mechanism 6 is provided inside the mounting seat 4. A pressure sensor 8 is fixedly mounted inside the right mounting bracket 2. The adjustment mechanism 7 includes a mounting ring 701 rotatably mounted inside the mounting bracket 2, and multiple sets of adjustment brackets 702 annularly distributed inside the mounting bracket 2. All sets of adjustment brackets 702 are rotatably connected to the mounting bracket 2 via mounting shafts 703, and the multiple sets of mounting shafts 703 are annularly distributed around the mounting ring 701. All sets of adjustment brackets 702 are... An adjusting rod 704 is fixedly installed, and the inner wall of the adjusting pipe 3 is fixedly bonded to multiple sets of adjusting rods 704. By setting an adjusting mechanism 7 that can dynamically adjust the diameter of the pipe 3, the diameter of the adjusting pipe 3 can be adjusted in real time according to feedback from the pressure sensor 8, effectively alleviating pressure fluctuations caused by changes in powder flow state and preventing the formation of local blockages. Simultaneously, combined with the multi-directional vibration generated by the shaking mechanism 5 and the differential shearing action of the stirring mechanism 6, it can efficiently break up electrostatic adsorption and agglomeration of powder. The gear 706 and gear ring 705 transmission structure ensures synchronous movement of multiple sets of adjusting rods 704, maintaining pipe roundness. The buffer design of two sets of first springs 502 causes the mounting frame 2 to generate a composite vibration frequency under the drive of the first cam 504, significantly improving the dispersion effect of agglomerated powder. Furthermore, the reverse rotation formed by the meshing of the first and second stirring frames 603 through the toothed column 605 further enhances the uniformity of the shear force field. This device achieves synergistic optimization of adaptive balance of conveying pressure and fluidization control of materials, reducing the risk of pipe blockage compared to a fixed pipe diameter design, and is suitable for the stable conveying of high-solids content coatings.

[0028] In this embodiment, reference Figure 5 , Figure 6 As shown, gears 706 are sleeved on multiple sets of mounting shafts 703, and gear rings 705 are sleeved on mounting rings 701. Multiple sets of gears 706 are meshed with gear rings 705. When paint or powder materials flow through regulating pipe 3, pressure sensor 8 monitors the pressure change in the pipe in real time. If an abnormal increase in pressure is detected, it may be due to material accumulation or reduced flowability. The regulating mechanism 7 is then activated. The motor on mounting frame 2 drives the mounting shafts 703 to rotate. In conjunction with multiple sets of annularly distributed gears 706 and gear rings 705 on mounting ring 701, multiple sets of gears 706 are driven to rotate synchronously, causing the regulating rods 704 on multiple sets of regulating frames 702 to move synchronously inward or outward, thereby dynamically adjusting the diameter of regulating pipe 3 and optimizing the material flow state.

[0029] In this embodiment, reference Figure 2 , Figure 3 and Figure 4 As shown, the shaking mechanism 5 includes a first slide rod 501 fixedly installed in the base 1. The mounting bracket 2 is slidably sleeved with the first slide rod 501. A stop block 503 is fixedly installed at the bottom of the mounting bracket 2, and a first cam 504 is rotatably installed on the base 1. The first cam 504 is fitted with the stop block 503. Two sets of symmetrically distributed first springs 502 are sleeved on the first slide rod 501. The two ends of the two sets of first springs 502 are fixedly connected to the mounting bracket 2 and the base 1, respectively. The stirring mechanism 6 includes a first slide rod 501 rotatably installed in the mounting base 4. A stirring frame 601 and a second stirring frame 603 are provided, with the second stirring frame 603 penetrating through the first stirring frame 601 and rotatably connected to it. A first toothed disc 602 is fixedly mounted on the first stirring frame 601, and a second toothed disc 604 is fixedly mounted inside the second stirring frame 603. A toothed column 605 is rotatably mounted inside the mounting base 4, located between the first toothed disc 602 and the second toothed disc 604, and meshing with both the first toothed disc 602 and the second toothed disc 604. The second stirring frame 603... A sliding frame 606 is slidably installed, and a second sliding rod 607 is fixedly installed inside the second stirring frame 603. The sliding frame 606 and the second sliding rod 607 are slidably sleeved together, and two sets of symmetrically distributed second springs 608 are sleeved on the second sliding rod 607. The two ends of the two sets of second springs 608 are fixedly connected to the sliding frame 606 and the second stirring frame 603, respectively. A second cam 609 is rotatably installed inside the second stirring frame 603, and the second cam 609 is fitted against the sliding frame 606. At the same time, the first cam 50 of the shaking mechanism 5... 4. The periodic push of the mounting frame 2 along the first slide bar 501 creates high-frequency reciprocating vibration under the action of two sets of first springs 502, effectively preventing powder deposition. Meanwhile, the stirring mechanism 6 drives the first and second stirring frames 603 to rotate in opposite directions through the meshing of the toothed column 605, generating strong shearing force to break up agglomerated materials. The second cam 609 drives the sliding frame 606 to reciprocate, further enhancing the stirring effect. This device achieves pipeline anti-blocking and adaptive adjustment of conveying pressure through the synergistic effect of pressure feedback closed-loop control, mechanical vibration and shearing stirring.

[0030] In this embodiment, when the coating or powder material flows through the regulating pipe 3, the pressure sensor 8 monitors the pressure change inside the pipe in real time. If an abnormal increase in pressure is detected, possibly due to material accumulation or reduced flowability, the regulating mechanism 7 is immediately activated. The motor on the mounting frame 2 drives the mounting shaft 703 to rotate, cooperating with multiple sets of annularly distributed gears 706 and the gear ring 705 on the mounting ring 701. This drives the multiple sets of gears 706 to rotate synchronously, causing the regulating rods 704 on the multiple sets of regulating frames 702 to move synchronously inward or outward, thereby dynamically adjusting the diameter of the regulating pipe 3 and optimizing the material flow state. At the same time, the first cam 504 of the shaking mechanism 5 periodically pushes the mounting frame 2 to slide along the first slide rod 501, forming a high-frequency reciprocating vibration under the action of the two sets of first springs 502, effectively preventing powder deposition; while the stirring mechanism 6 drives the first and second stirring frames 603 to rotate in opposite directions through the meshing of the toothed column 605, generating a strong shearing force to break up the clumps of material, and the second cam 609 drives the sliding frame 606 to reciprocate to further enhance the stirring effect. This device achieves pipeline anti-blocking and adaptive adjustment of conveying pressure through the synergistic effect of pressure feedback closed-loop control, mechanical vibration and shearing stirring.
