Description

Technical Field

[0001] This utility model relates to the field of polishing slurry drainage technology, specifically a polishing slurry drainage switching device. Background Technology

[0002] The polishing slurry is a water-soluble polishing agent that contains no sulfur, phosphorus, or chlorine additives. It possesses excellent degreasing, rust-preventing, cleaning, and brightening properties, enabling metal products to reveal a true metallic luster. It is stable, non-toxic, and environmentally friendly.

[0003] Polishing machines require continuous spraying of polishing slurry during the polishing process. After use, the slurry undergoes simple purification and is recycled back to a tank for reuse. However, simple purification cannot completely eliminate impurities in the slurry. With repeated use, impurities may clog the outlet pipes, requiring the polishing machine to be stopped during pipe repair, thus affecting the processing progress. Therefore, those skilled in the art have provided a polishing slurry drainage switching device to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a polishing fluid draining and switching device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A polishing slurry discharge switching device includes a polishing slurry tank, a cleaning mechanism, and a switching mechanism. The bottom end of the polishing slurry tank is connected to a pair of symmetrically arranged outlet pipes, each equipped with a solenoid valve at its upper end. A rotating rod is rotatably connected to the center of the bottom end of the polishing slurry tank, and a rocker wheel is fixedly connected to the end of the rotating rod. A fixed plate is fixedly connected to the outer wall of the rotating rod near the polishing slurry tank end. A switching mechanism is provided at the upper end of the fixed plate. A horizontal plate is fixedly connected to the outer wall of the rotating rod, and a cleaning mechanism is provided at the upper end of the horizontal plate.

[0007] As a further embodiment of this utility model: an external pipe is connected through and fixedly connected to one end of the horizontal plate, an inlet cover is fixedly connected to the end of the external pipe near the liquid outlet pipe, two sets of return springs are fixedly connected to the end of the horizontal plate away from the liquid outlet cover, a pipe plug is fixedly connected to the bottom end of the two sets of return springs, a limit slide rail is opened on the upper end surface of the pipe plug, a cleaning roller is slidably connected in the limit slide rail, and a servo motor is fixedly connected to the center of the bottom end inside the pipe plug.

[0008] As a further embodiment of this utility model: the power output end of the servo motor is fixedly connected to a first transmission rod, the upper end of which is fixedly connected to a drive gear; one end of the tube plug is rotatably connected to a second transmission rod; the end of the second transmission rod is fixedly connected to a driven gear; the driven gear abuts against and rotatably connects to the drive gear; a cleaning roller is fixedly connected to the upper end of the driven gear via a linkage rod; an internal gear is fixedly connected inside the tube plug; the internal gear abuts against and rotatably connects to the driven gear; and a limit plate is rotatably connected between the first transmission rod and the second transmission rod.

[0009] As a further embodiment of this utility model: a fixed rod is fixedly connected to the bottom end of the fixed plate, and a telescopic rod is slidably connected to the bottom end of the fixed rod. Multiple sets of through holes are opened in both the fixed rod and the telescopic rod. Insertion rods are connected inside and outside the through holes and are movably engaged with the through holes. Multiple sets of insertion slots are opened at the bottom end of the polishing liquid tank. The insertion slots are arranged at equal intervals with adjacent insertion slots, and the telescopic rods are movably engaged with the insertion slots.

[0010] As a further embodiment of this utility model: the driven gear meshes with the driving gear, and the driven gear meshes with the internal gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Because it is equipped with a cleaning mechanism, the liquid flow path can be switched by operating the rocker wheel. The horizontal plate rotates 180 degrees to align the liquid inlet hood and the outer pipe with the new liquid outlet pipe, which effectively ensures the rapid switching of the liquid flow direction. Through the effect of servo motor and gear transmission, the cleaning roller can be driven to move along the limit slide rail of the pipe plug to clean the inner wall of the liquid outlet pipe. The continuous movement of the cleaning roller effectively avoids the blockage of the inner wall of the liquid outlet pipe caused by impurities, deposits and other reasons.

[0013] 2. Because of the switching mechanism, the horizontal plate can be precisely fixed in the predetermined position after the switching is completed through the cooperation of the telescopic rod, the insertion slot and the insertion rod. After the horizontal plate is fixed, the position of the entire liquid switching will remain stable, reducing vibration or displacement during operation and preventing the horizontal plate from shifting due to shaking caused by external force or shaking caused by the servo motor, which could lead to leakage.

[0023] Example 2

This embodiment is based on the previous embodiment, but differs in that an outer pipe 6 is connected through and fixedly connected to one end of the horizontal plate 5. An inlet hood 7 is fixedly connected to the end of the outer pipe 6 near the outlet pipe 2. Two sets of return springs 8 are fixedly connected to the end of the horizontal plate 5 away from the inlet hood 7. A pipe plug 9 is fixedly connected to the bottom end of the two sets of return springs 8. A limit slide rail 10 is provided on the upper surface of the pipe plug 9.
