Description

Technical Field

[0001] This utility model relates to the field of ink processing technology, and in particular to an anti-settling device for a PCB ink mixer. Background Technology

[0002] An anti-settling device is a device that prevents solid particles from settling in a liquid through mechanical stirring, liquid circulation, or other means. It is used to maintain material uniformity, improve reaction efficiency, and enhance product quality. When applied to a PCB ink mixer, the anti-settling device is crucial for ensuring the quality of PCB ink and directly affects the precision and stability of subsequent printing.

[0003] Chinese utility model patent CN222039985U discloses a device for preventing the sedimentation of printing ink in plastic express bags, including a printing ink storage tank; a motor is installed on the side wall of the printing ink storage tank; a first gear is fixedly connected to the output end of the motor; a support frame is fixedly connected to the top of the inner side wall of the printing ink storage tank; a support shaft is rotatably connected to the middle of the support frame; a second gear is fixedly connected to the top of the support shaft, and the first gear and the second gear are connected by a synchronous belt; a stirring blade is fixedly connected to the middle of the support shaft; there are multiple stirring blades evenly distributed in the middle of the support shaft.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the ink used for printing may have a high viscosity, which easily forms sediment. Although multiple vertical stirring blades can stir the ink in the ink storage tank to a certain extent as the stirring blades rotate, if the stirring speed is too fast, ink vortexes are easily generated, and the ink level at the edge of the ink storage tank rises too high, posing a risk of splashing. If the stirring speed is too slow, it is difficult to mix the upper layer of ink with the lower layer of sediment evenly, affecting the ink's performance. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an anti-settling device for a PCB ink mixer.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a PCB ink mixer anti-settling device, comprising a storage tank, a rotating rod rotatably installed inside the storage tank, an upper auger blade and a lower auger blade fixedly sleeved on the rotating rod, the upper auger blade and the lower auger blade having opposite spiral directions, and a drive assembly for driving the rotating rod to rotate on the storage tank.

[0007] By adopting the above technical solution, during use, the operator needs to control the drive assembly to rotate the rotating rod. The rotating rod drives both the upper and lower auger blades to rotate, pushing the ink in opposite directions, ensuring thorough mixing of the upper and lower ink layers. This significantly reduces the probability of ink stratification and sedimentation due to gravity. This application changes the traditional design of using fixed stirring blades to agitate the ink, promoting uniform mixing of the upper ink layer and the lower sediment layer, reducing the probability of color differences during subsequent printing due to sedimentation, and ensuring the effectiveness of the ink.

[0008] Furthermore, the rotating rod passes through the bottom of the storage tank and is rotatably connected to the storage tank. The driving assembly includes a driven gear fixedly sleeved on the lower end of the rotating rod, a transmission rod rotatably mounted on the bottom of the storage tank, a driving gear fixedly sleeved on the transmission rod and meshing with the driven gear, a mounting bracket fixed to the bottom of the storage tank, and a drive motor fixed to the mounting bracket and driving the transmission rod to rotate.

[0009] By adopting the above technical solution, after the staff starts the drive motor, the drive motor works and drives the transmission rod fixed to it, the driving gear fixed to the transmission rod, the driven gear meshing with the driving gear, the rotating rod fixed to the driven gear, and the upper and lower auger blades fixed to the rotating rod to rotate, thereby making the upper and lower auger blades cooperate and making the ink in the storage tank fully mixed.

[0010] Furthermore, a sleeve is fixedly fitted on the rotating rod, and a crossbar is fixed to the outer wall of the sleeve. The bottom surface of the crossbar abuts against the inner bottom wall of the storage tank. Multiple crushed blocks are fixed on one side wall of the crossbar. The cross-section of the crushed blocks is a right-angled triangle. The distance between the side wall of the crushed block away from the crossbar and the crossbar decreases from top to bottom.

[0011] By adopting the above technical solution, the setting of the crushing block can break up a small amount of sediment, which is conducive to the rapid and uniform mixing of ink.

[0012] Furthermore, the crossbar has multiple through holes.

[0013] By adopting the above technical solution, the perforation reduces the resistance experienced by the crossbar during rotation with the rotating rod.

[0014] Furthermore, the rotating rod is provided with multiple sets of stirring components. Each set of stirring components includes a connecting rod fixed to the side wall of the rotating rod and a fixing rod fixed to the connecting rod, and each connecting rod has multiple fixing rods.

[0015] By adopting the above technical solution, the setting of the connecting rod and the fixed rod enhances the overall mixing uniformity of the ink. When the connecting rod and the fixed rod move in a circular motion along the axis of the rotating rod, they agitate the ink outside the convection circulation of the upper and lower auger blades, thereby enhancing the mixing uniformity inside the ink.

[0016] Furthermore, an upper rod is provided on the upper auger blade, and a lower rod is provided on the lower auger blade. A scraper is fixed to the end of the upper rod away from the rotating rod and the end of the lower rod away from the rotating rod. The side of the scraper away from the rotating rod abuts against the inner wall of the storage tank.

[0017] By adopting the above technical solution and designing the scraper, the probability of ink and other sediments adhering to the inner wall of the storage tank is reduced.

[0018] Furthermore, a rubber pad is attached and fixed to the side of the scraper away from the rotating rod, and the rubber pad abuts against the inner wall of the storage tank.

[0019] By adopting the above technical solution, the rubber pad is made of rubber and has a certain degree of flexibility and resilience. The rubber pad reduces the wear of the scraper on the inner wall of the storage tank.

[0020] Furthermore, a through groove is provided through the scraper.

[0021] By adopting the above technical solution, the design of the through groove reduces the resistance of the scraper as it moves with the upper and lower auger blades.

[0022] In summary, this utility model has the following beneficial effects: When in use, the operator needs to drive the rotating rod to rotate by controlling the drive component. The rotating rod drives both the upper and lower auger blades to rotate. The upper and lower auger blades push the ink in opposite directions, so that the upper and lower ink layers are fully mixed, which greatly reduces the probability of ink stratification due to gravity.

The upper auger blade 21 and lower auger blade 22 push the ink in opposite directions, so that the upper ink and the lower ink are fully mixed, which greatly reduces the probability of ink separation and sedimentation due to gravity.

[0028] In this embodiment, a sleeve 23 is fixedly fitted onto the rotating rod 2, and the axis of the rotating rod 2 coincides with the axis of the sleeve 23. A crossbar 4 is fixed to the outer wall of the sleeve 23, and the bottom surface of the crossbar 4 abuts against the inner bottom wall of the storage tank 1.
