Dust-free powder filling equipment for tubular object in single protection

Abstract

The invention discloses dust-free powder filling equipment for a tubular object in single protection. The equipment comprises a cylindrical rack, a powder box, an upper mold, a fixing device, a transition table, a vibration device and a control device, the powder box is used for placing powder for filling the tubular object, the upper mold is provided with a powder guide channel communicated witha discharge port; the fixing device supports the bottom of the tubular object, the transition table is used for limiting the middle of the tubular object, and the powder guide channel is provided witha switch valve. The bottom of a tubular object is placed on the fixing device, then the upper end of the tubular object is positioned through the upper mold, the upper end of the tubular object is connected with the powder guide channel, and the transition table is arranged between the upper mold and the fixing device, so that secondary positioning of the tubular object is facilitated; the amountof powder in the tubular object is controlled by controlling opening and closing of the switch valve through the control device, the volume of the powder in the tubular object can be obtained in timethrough the position sensor, the situation that the powder in the tubular object exceeds the preset filling amount is avoided, and dust pollution is reduced.

Description

technical field [0001] The invention relates to the field of powder filling equipment, in particular to a dust-free powder filling equipment for single-guaranteed tubular objects. Background technique [0002] Tubular objects are generally cylinders with accommodating space in the middle, such as electric heating tubes, lamp tubes, etc. During the processing of electric heating tubes and lamp tubes, plugs are generally installed on one end of the tubular object, and the other end is placed in the powder filling equipment. Corresponding powder (such as magnesium powder) is added into the containing space, so as to realize the effect of heat generation or light emission. [0003] However, the existing powder filling equipment has the following problems in the powder filling process: [0004] 1. When the powder filling equipment is adding powder to the metal tube, the powder leakage is serious, causing pollution to the working environment and waste of materials; [0005] 2. A...

AI Technical Summary

Problems solved by technology

Moreover, the poured powder is easily contaminated when it is recycled;

[0006] 3. Because the tube body is placed in the powder filling equipment, there is a certain gap between the powder layers during the adding process, and the density is poor;

[0007] 4. The existing powder filling equipment can only be used for single-length tubular objects, which has poor applicability;

[0008] 5. The existing powder filling equipment is generally large in size, and the dust in it is easy to pollute the machinery in it, resulting in accuracy errors
