Description

Technical Field

[0001] This utility model relates to the field of disc feeder technology, and in particular to a disc feeder with a feeding sealing structure. Background Technology

[0002] A disc feeder is a common feeding device used at the bottom of silos, and is widely used in metallurgy, coal, chemical, building materials, and grain industries. The disc feeder uses a motor to drive a disc to rotate at a constant speed. Material falls from the silo onto the disc through a discharge sleeve. As the disc rotates, the material is carried to a scraper plate, where it is scraped off and conveyed to the next piece of equipment. The following disadvantages exist in the actual use of this type of disc feeder: 1. Existing disc feeders can control the feeding amount by controlling the distance between the feeding sleeve and the disc. For highly viscous materials, there is a risk of blockage in the feeding sleeve. Furthermore, the material inside the feeding sleeve directly presses onto the disc, causing the disc to bear the additional weight of the material in the hopper, thereby aggravating the wear of transmission components such as bearings and shortening the service life of the equipment; 2. Existing disc feeders only support continuous discharge mode and cannot meet the needs of intermittent feeding, limiting their applicability in production scenarios with special requirements for feeding rhythm; 3. The feeding structure of existing disc feeders adopts an open design, which has the problems of easy material spillage, easy material contamination, and serious dust flying. Utility Model Content

One end of the first connecting rod 49 is fixedly connected to a second connecting rod 410. A slider 411 is connected to the second connecting rod 410 and is slidably connected to the scraper plate 412. A knob screw 41 is used to drive the mounting base 42 to slide up and down along the second guide rod 45. The first connecting rod 49 is used to drive the slider 411 via the second connecting rod 410. The slider 411 is used to drive one end of the scraper plate 412 to move towards the discharge pipe 21. The fixing rod 415 is used to install the top block 416, and the top block 416 is used to push the first connecting rod 49. A corresponding knob screw is installed on the mounting base 42.

The hinge 413 is used to achieve a hinged connection between the scraper 412 and the housing 2, and the elastic plate 414 is used to conform to the inner wall of the housing 2, preventing material from entering the gap between the scraper 412 and the housing 2. A discharge pipe 21 is fixedly connected to the lower surface of the housing 2, and the input end of the discharge pipe 21 is located on one side of the scraper 412. The discharge pipe 21 is used to discharge material from the housing 2.

[0021] Working principle: When using this utility model, the feed pipe 23 is connected to the output end of the hopper. The material in the hopper enters the feed pipe 23. If intermittent feeding is required, the knob screw 41 can be rotated. The knob screw 41 drives the mounting seat 42 through the threaded hole 43. The mounting seat 42 moves upward along the second guide rod 45 through the guide hole 44. The mounting seat 42 drives the connecting ring 46, and the first connecting rod 49 on the connecting ring 46 also moves accordingly. When the mounting seat 42 moves upward to the limit position, the first connecting rod 49... When the top block 416 is at the same height, the intermittent feeding mode is switched, and the motor 11 on the base 1 is started. The motor 11 drives the second gear 13 via the first gear 12. The second gear 13 drives the turntable 15 via the first rotating shaft 14. The turntable 15 drives the second rotating shaft 32 via the first guide rod 31. The spiral blades 35 on the second rotating shaft 32 rotate accordingly to assist in conveying the material in the feed pipe 23 and prevent the feed pipe 23 from being blocked. The turntable 15 drives the top block 416 via the fixing rod 415. During the movement of the top block 416, it pushes the first connecting rod 49. The connecting ring 46 at one end of the first connecting rod 49 deflects on the mounting base 42, causing the spring 48 to twist and deform. The other end of the first connecting rod 49 drives the slider 411 via the second connecting rod 410. The slider 411 drives the scraper 412, which deflects. The elastic plate 414 on the scraper contacts the inner wall of the housing 2, thereby preventing the material on the turntable 15 from entering the gap between the scraper 412 and the housing 2. When the top block 416 disengages... After the first connecting rod 49, the connecting ring 46 is reset under the action of the spring 48 until the limiting slot 47 is blocked by the second guide rod 45. At this time, the connecting ring 46 returns to its initial position. During the reset process of the connecting ring 46, the first connecting rod 49 drives the second connecting rod 410, the second connecting rod 410 drives the slider 411, and the slider 411 drives the scraper 412 to reset, so that the elastic plate 414 is separated from the inner wall of the housing 2, and the material can re-enter the gap between the scraper 412 and the housing 2.

[0022] To switch to continuous feeding mode, the knob screw 41 can be turned in the opposite direction, causing the mounting base 42 to move down to its limit position. At this time, the height of the first connecting rod 49 is lower than that of the top block 416, so the top block 416 cannot push the first connecting rod 49, so that the scraper 412 is in the normally open state, and the material can continuously enter the gap between the scraper 412 and the housing 2. The discharge pipe 21 is used to discharge the material from the housing 2, the cover plate 22 is used to close the top of the housing 2, and the hinge 413 is used to realize the hinge between the scraper 412 and the housing 2.
