The grinding, chamfering, and polishing structures are sequentially installed on the installation structure from the infeed side to the outfeed side. The chamfering structures include an upper chamfering structure and a lower chamfering structure. The chamfering structure is located on the side closest to the outfeed conveyor belt. This device can perform grinding, chamfering, polishing, and chamfering processes on opposite sides of ultra-thin glass, increasing production capacity.

[0004] The existing technology has the following technical defects:

[0005] Although the aforementioned patent can achieve grinding and polishing of ultra-thin glass, the ultra-thin glass is easily damaged due to excessive polishing pressure during the grinding process, resulting in waste of raw materials and affecting the production efficiency of ultra-thin glass. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a new type of hand-expanding shaft for a soft bag filling machine.

[0007] The precision grinding and polishing equipment for ultra-thin glass of this utility model includes an operating table, a polishing base fixedly connected to the top of the operating table, a lifting frame fixedly connected to the top of the operating table away from the polishing base, a lifting motor bolted to the top of the lifting frame, a lifting threaded rod fixedly connected to the output end of the lifting motor, the lifting threaded rod passing through the lifting frame and rotatably connected to the lifting frame, a lifting plate threadedly connected to the outer wall of the lifting threaded rod, a polishing mechanism provided inside the lifting plate, and an adjustment mechanism provided at the bottom of the lifting plate.

[0008] The polishing mechanism includes a polishing motor bolted to it, and a drive rod fixedly connected to the output end of the polishing motor. The drive rod passes through the lifting plate and is rotatably connected to the lifting plate. A rotating disk is fixedly connected to the bottom end of the drive rod.

[0009] The polishing mechanism also includes three spring-loaded threaded rods that pass through the rotating disk and are slidably connected to the spring-loaded threaded rods. The outer wall of the threaded portion at the top of the spring-loaded threaded rod is threadedly connected to the inner wall of the adjusting knob. The bottom of the adjusting knob is rotatably connected to the top of the rotating disk. The bottom of the spring-loaded threaded rod passes through the polishing disk and is slidably connected to the polishing disk. A pressure plate is fixedly connected to the bottom end of the spring-loaded threaded rod. A spring-loaded spring is provided on the outer wall of the spring-loaded threaded rod located between the rotating disk and the polishing disk.

[0010] The polishing disc has a polishing chamber inside, and the inner wall of the polishing chamber is slidably connected to the outer wall of the pressure plate.

[0011] The adjustment mechanism includes multiple feeding slots located at the bottom of the polishing chamber, and a feeding plate is slidably connected to the inner wall of the feeding slot. A feeding spring is provided between the bottom of the feeding plate and the bottom of the feeding slot.

[0012] The adjustment mechanism also includes four connection ports on the inner wall of the feeding trough, and a discharge port is provided on one side of the connection port, the bottom of which penetrates the bottom of the polishing disc.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, the lifting motor is first started, which drives the lifting threaded rod to rotate. The rotating threaded rod, through its thread, drives the lifting plate to move vertically. Then, the polishing motor is started, which drives the drive rod to rotate. The drive rod, in turn, drives the rotating disk to rotate. The rotating disk, through its return threaded rod, drives the polishing disk to rotate. The rotating polishing disk, via the vertically moving lifting plate, can move downwards while rotating, polishing the ultra-thin glass mounted on the top of the polishing base. Rotating the adjustment knob, through its thread, drives the return threaded rod to move vertically. This vertically moving return threaded rod adjusts the distance between the rotating disk and the polishing disk, thereby adjusting the spring force applied to the polishing disk. This allows for precise adjustment of the polishing pressure applied to glass of different thicknesses, avoiding damage due to excessive polishing pressure and thus reducing production costs.

[0015] In this invention, when the polishing disc is pressed against the top of the ultra-thin glass, the pressure of the ultra-thin glass and the elasticity of the rebound spring drive the pressure plate to move vertically inside the polishing chamber. The vertically moving pressure plate can squeeze the polishing paste inside the polishing chamber. The squeezed polishing paste applies pressure to the feeding plate, thereby driving the feeding plate to slide inside the feeding groove. After the feeding plate slides to the bottom of the connection port, the polishing paste enters the discharge port through the connection port, and is then squeezed to the top of the ultra-thin glass through the discharge port. This allows for continuous addition of polishing paste during the polishing process, reducing the step of manually adding polishing paste and improving the efficiency of polishing.

[0022] Example 1

[0023] like Figures 1-5As shown, this utility model provides a technical solution: a precision grinding and polishing device for ultra-thin glass, including an operating table 1, a polishing base 2 fixedly connected to the top of the operating table 1, a lifting frame 3 fixedly connected to the top of the operating table 1 away from the polishing base 2, a lifting motor 4 bolted to the top of the lifting frame 3, a lifting threaded rod 5 fixedly connected to the output end of the lifting motor 4, the lifting threaded rod 5 passing through the lifting frame 3 and rotatably connected to the lifting frame 3, a lifting plate 6 threadedly connected to the outer wall of the lifting threaded rod 5, a polishing mechanism disposed inside the lifting plate 6, and an adjustment mechanism disposed at the bottom of the lifting plate 6; the polishing mechanism includes a polishing motor 7 bolted to it, and a drive rotating rod 8 fixedly connected to the output end of the polishing motor 7. The drive rod 8 passes through the lifting plate 6 and is rotatably connected to it. A rotating disk 9 is fixedly connected to the bottom end of the drive rod 8. The polishing mechanism also includes three spring-loaded threaded rods 10 that pass through the rotating disk 9 and are slidably connected to each other. The outer wall of the threaded portion at the top of the spring-loaded threaded rod 10 is threadedly connected to the inner wall of the adjusting knob 11. The bottom of the adjusting knob 11 is rotatably connected to the top of the rotating disk 9. The bottom of the spring-loaded threaded rod 10 passes through the polishing disk 12 and is slidably connected to it. A pressure plate 20 is fixedly connected to the bottom end of the spring-loaded threaded rod 10. A spring-loaded spring 13 is provided on the outer wall of the spring-loaded threaded rod 10 located between the rotating disk 9 and the polishing disk 12. A polishing chamber 14 is provided inside the polishing disk 12. The inner wall of the polishing chamber 14 is slidably connected to the outer wall of the pressure plate 20. First, the lifting motor 4 is started, and the rotation of the lifting motor 4 drives the lifting threaded rod 5 to rotate. The rotating lifting threaded rod 5 drives the lifting plate 6 to move vertically through the thread action. Then, the polishing motor 7 is started, and the rotation of the polishing motor 7 drives the drive rod 8 to rotate. The drive rod 8 drives the rotating disk 9 to rotate. The rotating disk 9 drives the polishing disk 12 to rotate through the return threaded rod 10. The rotating polishing disk 12 can move downwards while rotating through the vertically moving lifting plate 6 to polish the ultra-thin glass installed on the top of the polishing base 2. The adjustment knob 11 is rotated, and the rotation of the adjustment knob 11 drives the return threaded rod 10 vertically through the thread action. The vertically moving spring-loaded threaded rod 10 can adjust the distance between the rotating disk 9 and the polishing disk 12, thereby adjusting the spring force applied by the spring 13 to the polishing disk 12. This facilitates precise adjustment of the polishing pressure applied to glass of different thicknesses, avoiding damage due to excessive polishing pressure and thus increasing production costs. The adjustment mechanism includes multiple feeding grooves 15 located at the bottom of the polishing chamber 14, and a feeding plate 16 is slidably connected to the inner wall of the feeding groove 15. A feeding spring 17 is provided between the bottom of the feeding plate 16 and the bottom of the feeding groove 15. The adjustment mechanism also includes four connecting ports 18 located on the inner wall of the feeding groove 15, and a discharge port 19 is provided on one side of the connecting port 18. The bottom of the discharge port 19 penetrates the bottom of the polishing disk 12.When the polishing disc 12 presses against the top of the ultra-thin glass, the pressure of the ultra-thin glass and the elasticity of the rebound spring 13 drive the pressure plate 20 to move vertically inside the polishing chamber 14. The vertically moving pressure plate 20 can squeeze the polishing paste inside the polishing chamber 14. The squeezed polishing paste applies pressure to the feeding plate 16, thereby driving the feeding plate 16 to slide inside the feeding groove 15. After the feeding plate 16 slides to the bottom of the connecting port 18, the polishing paste enters the discharge port 19 through the connecting port 18, and is then squeezed onto the top of the ultra-thin glass through the discharge port 19. This allows for continuous addition of polishing paste during the polishing process, reducing the step of manually adding polishing paste and improving the efficiency of polishing.

[0024] Working process or principle:

[0025] First, start the lifting motor 4. The rotation of the lifting motor 4 drives the lifting threaded rod 5 to rotate. The rotating lifting threaded rod 5 drives the lifting plate 6 to move vertically through the thread action. Then, start the polishing motor 7. The rotation of the polishing motor 7 drives the drive rod 8 to rotate. The drive rod 8 drives the rotating disk 9 to rotate. The rotating disk 9 drives the polishing disk 12 to rotate through the spring threaded rod 10. The rotating polishing disk 12 can move downwards while rotating through the vertically moving lifting plate 6 to polish the ultra-thin glass installed on the top of the polishing base 2. Rotate the adjustment knob 11. The rotation of the adjustment knob 11 drives the spring threaded rod 10 to move vertically through the thread action. The vertically moving spring threaded rod 10 can adjust the distance between the rotating disk 9 and the polishing disk 12, thereby adjusting the elastic force applied by the spring 13 to the polishing disk 12. This allows for precise adjustment of the polishing pressure applied to glass of different thicknesses, avoiding damage due to excessive polishing pressure and thus avoiding increased production costs.

[0026] When the polishing disc 12 is pressed on top of the ultra-thin glass, the pressure of the ultra-thin glass and the elasticity of the rebound spring 13 drive the pressure plate 20 to move vertically inside the polishing chamber 14. The vertically moving pressure plate 20 can squeeze the polishing paste inside the polishing chamber 14. The squeezed polishing paste applies pressure to the feeding plate 16, thereby driving the feeding plate 16 to slide inside the feeding groove 15. After the feeding plate 16 slides to the bottom of the connecting port 18, the polishing paste enters the discharge port 19 through the connecting port 18, and is then squeezed to the top of the ultra-thin glass through the discharge port 19. This allows for continuous addition of polishing paste during the polishing process, reducing the step of manually adding polishing paste and improving the efficiency of polishing.
