Description

Technical Field

[0001] The invention relates to the technical field of insulating powder production, in particular to an insulating powder dipping production line. Background Art

[0002] Insulating powder usually refers to some fine powder materials with good insulating properties, which are mainly used for the insulation of electrical and electronic equipment. In recent years, the coating technology of electrical epoxy insulating powder has been widely used in busbars, copper bars, switch cabinets, insulators, bus ducts and other electrical components that need to withstand high voltage. In the process of insulating powder production, an insulating powder dipping production line is required.

[0003] For example, the patent with publication number CN215464916U discloses an insulating powder dipping production line. This patent solves the problem of poor discharging effect of common insulating powder dipping production lines through the cooperation of a crushing motor, a crushing shaft, a crushing blade, a screen, a discharging port, a movable slot, a telescopic rod, a discharging plate, a reset spring, an electric push rod, a push plate and a feed hopper. When discharging, the insulating powder can be quickly discharged through the discharging port, thereby avoiding the blockage of the discharging port, thereby greatly improving the production efficiency of the insulating powder dipping production line. However, in the actual use of such equipment, some oversized particles will be blocked by the screen, and in the process of continuous feeding, the blocked particles will increase, and there is a gap between the crushing blade and the screen, which affects the crushing effect of these powder particles, resulting in the accumulation of too much material on the screen, which affects the efficiency of other powder particles passing through.

The scraper is spiral-shaped and is slidably connected to the shell, and a reinforcing rod is arranged between the scrapers.

[0016] The present invention provides an insulating powder dipping production line, which has the following beneficial effects:

[0017] 1. The pulverizing motor of the present invention drives the pulverizing roller to rotate, and after the material particles are pulverized, the material particles will slide down the guide flow of the guide plate and the guide frame to one end inside the sieve tube. At this time, the pulverizing roller will also drive the sieve tube to rotate through the synchronous gear, the transmission gear and the gear ring, and the spiral blades inside the sieve tube will gradually push the material particles to the other end. In this process, the powder particles that meet the requirements will be discharged from the discharge port through the sieve holes, and some of the powder particles that are too large will be moved out of the shell by the spiral blades, thereby avoiding the continuous accumulation of material particles inside the sieve tube and preventing the subsequent discharge effect from being affected. At the same time, during the rotation of the sieve tube, the bottom of the guide plate will be squeezed by the top block to make it rotate, and the guide plate will be reset under the action of automatic gravity during separation, so that the guide plate can vibrate to prevent the powder particles from continuously adhering to the guide plate.

[0018] 2. In the present invention, while the gear ring drives the screening tube to rotate, the driven gear will also rotate, and in the process of the driven gear rotating one circle, the lifting plate will be pulled down or pushed up by the sliding column to slide up and down along the limit rod, thereby pushing and pulling the connecting plate reciprocatingly through the connecting rod, driving the feeding plate to slide reciprocatingly in the collecting box. Therefore, after the screening tube transports the oversized powder particles into the collecting box, the powder particles will accumulate above the feeding plate, and when the feeding plate moves to the left, the powder particles will fall to the right end of the feeding plate, and when the feeding plate moves to the right, the larger powder particles can be pushed back to the bottom of the feeding tube, so that the spiral rod can re-feed the material, thereby the material particles can be re-crushed without adding an additional power source, with a high degree of automation and labor-saving and convenient operation.

[0019] 3. In the present invention, after the spiral rod conveys the material particles inside the feeding tube to the upper end, the material particles will be discharged from the discharge tube. At this time, the material dividing cover will guide the material particles so that their falling position is just distributed along the length direction between the two crushing rollers, avoiding the accumulation of materials at a certain place on the crushing roller, which is beneficial to improving the efficiency of material particle crushing. When the spiral rod rotates, it will also drive the limit plate to rotate synchronously. At this time, the protrusion will intermittently squeeze the pulley, so that the lifting frame drives the material dividing cover to move downward, and when the protrusion is separated from the pulley, the spring seat will drive the material dividing cover to reset, so that the material dividing cover can continue to vibrate, making the material more even when it is scattered, and can also reduce the jamming of material particles inside the material dividing cover when they fall.

[0020] 4. When the screening tube rotates, the present invention also drives the rotating seat to rotate through the first bevel gear ring and the second bevel gear ring, so that the scraper at the bottom can scrape and clean the inner wall of the lower end of the shell to reduce the adhesion of powder particles. At the same time, since the scraper is spiral, there will be a downward component of force when pushing the material, so that the discharge process is more thorough. At the same time, the reinforcing rod can reinforce the two scrapers, reduce the deformation of the scrapers, and improve the fit between the scrapers and the shell. The retaining ring can also be used to block the second bevel gear ring to prevent powder particles from falling on the second bevel gear ring and affecting the normal operation of the scraper assembly.

[0033] The specific operation is as follows: the screening tube 702 will transport the oversized powder particles to the collecting box 801, and the powder particles will accumulate on the top of the feeding plate 802.

At this time, the material distribution cover 208 will guide the material particles to prevent the materials from being concentrated and accumulated at a certain place on the crushing roller 4, and while the screw rod 203 rotates, it will also drive the limit plate 204 to rotate synchronously. At this time, the protrusion 205 will intermittently squeeze the pulley 206, so that the lifting frame 207 drives the material distribution cover 208 to move downward, and when the protrusion 205 is separated from the pulley 206, the spring seat 209 will drive the material distribution cover 20 8 is reset, so that the material distribution cover 208 can continue to vibrate, making the material more evenly scattered. Secondly, the crushing motor 3 will drive the crushing roller 4 to rotate to crush the material particles.

At the same time, during the rotation of the screening tube 702 , the spiral blade 703 inside it will gradually push the material particles to the other end. In this process, the powder particles that meet the requirements will be discharged from the discharge port 10 through the sieve hole 704, and some of the powder particles that are too large will be transported to the collection box 801 by the spiral blade 703. Then, the oversized powder particles will accumulate on the top of the feeding plate 802.

Finally, in the process of discharging, some powder particles will adhere to the inner side of the lower end of the shell 1. At this time, the screening tube 702 will also drive the rotating seat 903 to rotate through the first bevel gear ring 901 and the second bevel gear ring 902, so that the scraper 905 at the bottom can scrape and clean the inner wall of the lower end of the shell 1. At the same time, the reinforcing rod 906 can reinforce the two scrapers 905, and the top of the retaining ring 904 fits with the inner sides of the shell 1, so as to shield and protect the second bevel gear ring 902, and then the material will be discharged from the discharge port 10.
