Disclosed in the invention is a solid amalgam mercury-injection device for fluorescent tube production. The device comprises a fixed seat and a hopper; small holes in a loop mode are formed at the bottom of the hopper, wherein each of the small holes only can accommodate one solid amalgam; and the included angel between the hopper and the horizontal plane is an acute angle. A hopper installing seat is fixedly arranged at the fixed seat; a placing hole for hopper placing is formed at the hopper installing seat; a leakage hole matching the small holes is formed in the bottom of the placing hole of the hopper installing seat; and a sensor for sensing the number of particles is arranged in the leakage hole. Besides, a drive shaft is arranged at the fixed seat; and the end portion of the drive shaft presses on the end surface of the hopper to drive the hopper to rotate in the placing hole. According to the invention, the mercury injection precision is high; and the device can be operated conveniently. The provided device can be widely applied to the solid amalgam mercury-injection field of the fluorescent tube production.
Description
technical field [0001] The invention relates to a solid amalgam mercury injection device, in particular to a solid amalgam mercury injection device used in the production of fluorescent lamp tubes. Background technique [0002] Mercury guns are used to add mercury to the tube during the venting phase of the fluorescent tube production process. Because the solid amalgam particles are small, the amount of solid amalgam injected into the mercury gun is not easy to control, often resulting in the phenomenon of many or few particles. In order to solve the above problems, the structural control of hopper plus leak hole can be adopted. For example, Chinese Patent Application No. 200810059705.5 discloses a solid amalgam mercury injection device for fluorescent lamp tube production, which includes a base and a mercury storage hopper. The feature is that the base The upper part is fixed with a bottom plate and a hopper mounting plate, the hopper mounting plate is provided with a shaf...
