Description

Technical Field

[0001] The utility model relates to the technical field of quantitative feeding, in particular to a quantitative feeding device for lubricating powder. Background Art

[0002] Lubricating powder is a white powder made from natural minerals such as talc or synthetic ingredients, which has good lubricity and moisture resistance. It is usually used in moisture-proofing, dust removal, waterproofing and lubrication. In industry, lubricating powder is widely used to reduce friction and lubricate.

[0003] At present, when lubricating powder is fed into packaging machinery, it is usually fed by weighing with an auger-type quantitative feeding after weighing with the help of a quantitative feeder composed of a weighing hopper and an auger conveying pipe. However, when this quantitative feeder, as a quantitative feeding device, quantitatively discharges lubricating powder downward at the vertical pipe of the feeding pipe, the auger feeding discharge speed is prone to be too fast at the inner cavity mouth of the vertical pipe of the feeding pipe, resulting in excessive discharge of lubricating powder. For this reason, we propose a lubricating powder quantitative feeding device. Utility Model Content

[0004] The main purpose of the utility model is to provide a quantitative feeding device for lubricating powder, in which a control and discharge mechanism is arranged at the vertical row pipe of the quantitative feeder, and the control and discharge mechanism forms a controllable opening structure in the vertical row pipe. As the cross-cut groove on the surface of the rubber disk of the control and discharge mechanism is pressed down to open and expose the feeding opening, the lubricating powder can normally fall through the feeding opening opened at the cross-cut groove at the vertical row pipe to feed the lubricating powder packaging machine. When the quantitatively discharged material of the quantitative feeder is about to be discharged, the cylinder can pull the double-mouth cone bucket up, so that the feeding opening is gradually closed, so that the lubricating powder discharged excessively in the auger pipe is caught by the rubber disk, so as to realize the precise quantitative feeding of the lubricating powder at the packaging machine, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Furthermore, an inner tube wall of the vertical tube is provided with an internal thread wall for screwing the top cover and the inner rotating ring;

[0008] By adopting the above technical solution, the inner tube wall of the vertical tube can be screwed and installed with the top cover and the inner rotating ring by means of the inner threaded wall.

[0009] Furthermore, the cover body of the top cover is a cylindrical cover body, and an external threaded wall is arranged outside the vertical cylinder wall of the top cover;

[0010] By adopting the above technical solution, the top cover of the cylindrical cover body can be screwed and installed in the upper pipe opening of the vertical pipe row with the external threaded wall outside the vertical cylinder wall.

[0011] Furthermore, the diameter of the hole of the connecting hole is larger than the diameter of the tube of the internal threaded tube;

[0015] Furthermore, the plate body of the connecting plate is a long plate body with an inclined surface structure;

[0016] By adopting the above technical solution, the inclined surface of the connecting plate allows the lubricating powder that falls on its own plate surface to slide downward under the action of gravity.

[0018] The utility model provides a control and discharge mechanism at the vertical row pipe of the quantitative feeder, and the control and discharge mechanism forms a controllable opening structure in the vertical row pipe. As the cross-cut groove on the surface of the rubber disk of the control and discharge mechanism is pressed down to open and expose the drop opening, the lubricating powder can normally fall through the drop opening opened at the cross-cut groove at the vertical row pipe to be fed to the lubricating powder packaging machine for feeding. When the quantitatively discharged material of the quantitative feeder is about to be discharged, the cylinder can pull the double-mouth cone bucket up to make the drop opening gradually closed, so that the rubber disk can catch the lubricating powder discharged excessively in the auger pipe, thereby realizing accurate quantitative feeding of the lubricating powder at the packaging machine.

[0025] The inner tube wall of the vertical tube 2 is provided with an internal thread wall for screwing the top cover 10 and the inner rotating ring 4;

[0026] By adopting the above technical solution, the inner tube wall of the vertical tube 2 can be screwed and installed with the top cover 10 and the inner rotating ring 4 by means of the inner threaded wall.

[0027] The cover body of the top cover 10 is a cylindrical cover body, and an external threaded wall is arranged outside the vertical cylinder wall of the top cover 10;

[0028] By adopting the above technical solution, the top cover 10 of the cylindrical cover body can be screwed and installed in the upper pipe opening of the vertical pipe 2 with the external threaded wall outside the vertical cylinder wall.

[0029] The diameter of the middle connecting hole 11 is larger than the diameter of the internal threaded tube 12.

[0030] By adopting the above technical solution, the internal threaded pipe 12 can be inserted into the hole body of the middle connecting hole 11.

[0031] The small opening of the double-mouth cone bucket 7 faces the lower opening of the vertical pipe 2, and the connecting plate 8 is welded in the middle of the large opening of the double-mouth cone bucket 7, and the bottom rod body of the connecting rod 9 is welded in the middle of the upper plate surface of the connecting plate 8;
