Furthermore, the limiting structure comprises a gear, a one-way bearing and a rack, the gear is rotatably connected to the inner sliding plate, the one-way bearing is arranged at a rotating shaft of the gear and limits the gear to rotate in one direction, the rack is arranged on the inner wall of the shell, and the gear is meshed with the rack.

Furthermore, two guide rods are fixed on the outer sleeve plate, a sliding groove for the guide rods to slide is formed in the inner sliding plate, the inner sliding plate slides relative to the axis of the guide rods, the springs are respectively sleeved on the outer sides of the two guide rods, and two ends of each spring are respectively abutted against the outer sleeve plate and the inner sliding plate.

Further, the outer sleeve plate comprises a first outer plate and a second outer plate which are mutually spliced, a connecting piece is integrally arranged on the feeding shaft, a screw rod penetrates through the first outer plate and the second outer plate together, the screw rod penetrates through the connecting piece, a nut is in threaded connection with the screw rod, and the nut is abutted against the first outer plate or the second outer plate.

Furthermore, the longitudinal section of the inner sliding plate is in a T shape.

Has the advantages that: by the removal of spring drive inner slide, inner slide removes the back and the inner wall of laminating casing to because one-way bearing's the reason, inner slide can not reverse movement, so inner slide can laminate the inner wall of casing all the time, guarantees the leakproofness, can not putty and reduce blanking efficiency.

Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in figure 1, the sealed feeder of the preferred embodiment of the utility model comprises a shell 1, a feeding shaft 2 and a scraping assembly 3, wherein the scraping assembly 3 comprises an outer sleeve plate 4 and an inner sliding plate 5. Scrape material subassembly 3 and rotate along with feeding shaft 2, scrape the leakproofness that material subassembly 3 keeps and between 1 inner wall of casing, avoid the inside and 3 leakproofness of scraping material subassembly of casing 1 poor and cause the condition of putty.

As shown in FIG. 2, the outer sleeve plate 4 is fixed on the feeding shaft 2, the inner sliding plate 5 can slide relative to the outer sleeve plate 4, the sliding direction of the inner sliding plate 5 is along the direction far away from the feeding shaft 2, the sliding direction of the inner sliding plate 5 is unidirectional, and can be jointed with the inner wall of the shell 1.

The inner wall of the outer sleeve plate 4 and the inner sliding plate 5 are provided with a limiting structure for limiting the movement of the inner sliding plate 5. The limiting structure comprises a gear 6, a one-way bearing 7 and a rack 8.

The inner sliding plate 5 is arranged on the inner side of the outer sleeve plate 4 in a relatively sliding mode, one end of the inner sliding plate 5 protrudes out of the outer sleeve plate 4, the gear 6 is connected to the inner sliding plate 5 in a rotating mode, the one-way bearing 7 is arranged at the rotating shaft of the gear 6, the one-way bearing 7 limits the gear 6 to rotate in the one-way mode, the rack 8 is arranged on the inner wall of the shell 1, and the gear 6 is meshed with the rack 8.

The unidirectional rotation of the gear 6 is limited by the unidirectional bearing 7, and after the unidirectional rotation of the gear 6, the inner sliding plate 5 can only slide in a unidirectional way and gradually protrudes out of the surface of the outer sleeve plate 4. The inner part of the outer sleeve plate 4 is provided with a spring 10 for driving the inner sliding plate 5 to slide, and two ends of the spring 10 are respectively abutted against the inner wall of the outer sleeve plate 4 and the inner sliding plate 5.
