Description

Technical Field

[0001] The invention belongs to the technical field of energy-saving motors, and in particular relates to an energy-saving grinder for release film structure analysis. Background Art

[0002] Release films are mostly multi-layer composite structures, and the layer thickness and glue resistance performance need to be studied. They are thin in texture and have fuzzy boundaries between layers, making it difficult to discern details through direct observation. Grinding them with a grinder can clearly expose the structure of each layer and the glue penetration boundary, providing effective support for detecting the release film's glue resistance and layer thickness.

[0003] Currently, when using traditional grinders to grind release films, since the release film itself is thin and has a certain degree of softness, in order to obtain better research results, it is necessary to continuously adjust the grinding pressure on the release film. Therefore, the load variation on the grinder is large. When the grinding pressure is too high, if the motor output power is insufficient, it will affect the grinding quality and efficiency of the release film. When the grinding pressure is too low, if the motor output power is too high, the grinding disc speed will be too fast, which not only affects the grinding quality of the release film, but also causes unnecessary energy consumption. This "pressure and power" mismatch problem has become a key contradiction restricting the grinding effect and energy consumption control. Summary of the Invention

[0024] The outer side of the grinding disc 32 is provided with a water-repellent rubber ring 13 installed inside the mounting hole, and the bottom of the water-repellent rubber ring 13 extends to the inside of the mounting cover 31. The two mounting covers 31 are fixedly connected with a three-way drainage pipe 14, and the water outlet end of the three-way drainage pipe 14 is set on the outside of the outer shell 1. Through the three-way drainage pipe 14, the water entering the inside of the mounting cover 31 can be conveniently discharged.

[0025] The operating principle of the present invention is now explained as follows: the release film to be processed is placed on the corresponding grinding disc 32 through a special fixture (the number of grinding units 3 is 2, and grinding sand discs of different fineness can be installed on the two grinding discs 32, which can be selected according to actual needs). Then, the control board 2 is started through the control panel at the shell 1. The control board 2 will control the frequency conversion motor 34 to work at a preset power. The frequency conversion motor 34 drives the grinding disc 32 to rotate through the rotating shaft 33, so that the release film can be ground. When the rotating shaft 33 rotates, it will drive the rotating ring 5 to rotate synchronously through the mounting plate 4. At this time, the light-transmitting hole 7 on the side wall of the rotating ring 5 will pass through the light source 81 and the photoelectric switch 82. When the light-transmitting hole 7 passes, the light emitted by the light source 81 will pass through the light-transmitting hole 7 and irradiate the photosensitive surface of the photoelectric switch 82. At this time, the photoelectric switch 82 will The optical signal is converted into an electrical signal and fed back to the photoelectric signal counter 83, and the photoelectric signal counter 83 feeds back the measured number of electrical signals to the control mainboard 2 every 3 seconds. When the friction between the grinding disc 32 and the release film is too large, under the same preset power, the rotation speed of the grinding disc 32 is less than the preset speed corresponding to the preset power. Therefore, within 3 seconds, the number of electrical signals fed back by the photoelectric switch 82 is lower than the number of electrical signals corresponding to the preset speed. At this time, the control mainboard 2 will control the corresponding frequency conversion motor 34 to increase the output power through the frequency conversion module, so that the speed of driving the grinding disc 32 is increased, ensuring that the number of electrical signals fed back by the photoelectric switch 82 within 3 seconds is within the range of the number of electrical signals corresponding to the preset speed. The control mainboard 2 controls the frequency conversion motor 34 to continue working at the current power, thereby ensuring the efficiency and quality of grinding the release film; Similarly, when the friction between the release film and the grinding disc 32 is relatively small, within 3 seconds, the number of electrical signals fed back by the photoelectric switch 82 is higher than the number of electrical signals corresponding to the preset speed. At this time, the control motherboard 2 will reduce the output power of the variable frequency motor 34 through the frequency conversion module. When the number of electrical signals fed back by the photoelectric switch 82 within 3 seconds is within the range of the number of electrical signals corresponding to the preset speed, the control motherboard 2 controls the variable frequency motor 34 to continue operating at the current power. This can prevent the grinding disc 32 from rotating too fast and affecting the grinding quality, and can effectively reduce unnecessary energy consumption. The photoelectric signal counter 83 resets the time every 3 seconds, and at the same time, the photoelectric signal counter 83 accumulates and measures the electrical signal. As the shaft 33 rotates, the lubricating oil at the bearing of the shaft 33 gradually evaporates and ages under high temperature, affecting the smoothness of the rotation of the shaft 33. Therefore, it is necessary to regularly add lubricating oil to the bearing of the shaft 33. The photoelectric switch 82 cooperates with the light source 81 and the light-transmitting hole 7 of the rotating ring 5 to accumulate and measure the number of rotations of the shaft 33. When the accumulated number of rotations of the shaft 33 reaches a preset value (the preset value can be pre-set through the control panel of the housing 1 according to parameters such as the type of lubricating oil and the temperature of the site), the control mainboard 2 will automatically start the lubricating oil addition process to ensure that the bearing of the shaft 33 is sufficiently lubricated, effectively avoiding the phenomenon that the variable frequency motor 34 needs to consume more energy to drive the shaft 33 to rotate due to insufficient lubrication, thereby indirectly reducing energy consumption. At the same time, during the grinding process, if the lubrication of the bearing of the rotating shaft 33 is insufficient, the rotation resistance of the rotating shaft 33 becomes larger, which will cause the friction between the balls inside the bearing and the inner and outer rings to intensify and become uneven, resulting in intermittent jamming. The fluctuation of this friction resistance will be transmitted to the grinding disc 32 through the rotating shaft 33, causing the grinding disc 32 to vibrate periodically. At the same time, the bearing wear caused by insufficient lubrication will destroy the rotation coaxiality, causing the rotation center of the grinding disc 32 to shift, further amplifying the vibration amplitude, and the rotating shaft 33 will also transmit the vibration to the rotating ring 5 through the mounting plate 4, rotating The rotating ring 5 squeezes the ball bearing on the top block 96, causing the support rod 92 to move downward, which in turn squeezes the contact end of the pressure switch 94 on the same side. At this time, the pressure switch 94 will feedback an electrical signal to the pressure signal counter 95. If the number of electrical signals measured by the pressure signal counter 95 exceeds 5 within 30 seconds, the control board 2 will also start the lubricating oil addition process (the pressure signal counter 95 accumulates the measurement within 30 seconds to avoid accidental contact caused by occasional vibration of the grinding disc 32 due to uneven grinding pressure); When the control main board 2 starts a lubricating oil adding operation, the control main board 2 will control the electric push rod 103 to work regularly for 2 seconds, and control the corresponding electric control valve 115 to be energized and open for 5 seconds. When the electric push rod 103 pushes the pushing piston 102 to move upward, the lubricating oil inside the oil cylinder 101 will be pushed upward and discharged into the oil supply pipe 111 through the circular tube 114 opened by the electric control valve 115, and finally discharged into the bearing of the rotating shaft 33 through the oil discharge hole 113 at the hollow ring 112, so that the lubricating oil can be automatically added to the bearing of the rotating shaft 33 to ensure smooth rotation of the rotating shaft 33.
