In order to facilitate the display of the relevant structure of the anti-blocking blanking valve, a cross-sectional treatment is performed in a partial area of fig. 1 and 2. As shown in fig. 1 to 5, the anti-blocking blanking valve provided in the first embodiment of the present utility model includes a housing 10, a valve core 20 and a scraping rod 30, a feed inlet 11 and a discharge outlet 12 are respectively provided at an upper portion and a lower portion of the housing 10, the valve core 20 is rotatably provided in the housing 10, a plurality of feed grooves 21 and a plurality of scraping grooves 22 are formed on a surface of the valve core 20, each feed groove 21 extends along an axial direction of the valve core 20, the plurality of feed grooves 21 are arranged at intervals along a circumferential direction of the valve core 20, each scraping groove 22 extends along a circumferential direction of the valve core 20 and is annularly arranged on the valve core 20, and the plurality of scraping grooves 22 are arranged at intervals along an axial direction of the valve core 20. A scraping rod 30 is further arranged on the shell 10, and one end, away from the shell 10, of the scraping rod 30 extends into the scraping groove 22.
In this embodiment, when the material is fed, the material may be first fed into the housing 10 from the feed inlet 11, the material entering the housing 10 falls into the material conveying groove 21 of the valve core 20, and the material in the material conveying groove 21 is rotated to the discharge outlet 12 and flows out from the discharge outlet 12 along with the rotation of the valve core 20. Due to the arrangement of the scraper bar 30 and the scraper groove 22, the scraper bar 30 moves relative to the scraper groove 22 along with the rotation of the valve core 20. Since the scraping groove 22 is annularly arranged on the surface of the valve core 20, an intersecting area is formed between the scraping groove 22 and the material conveying groove 21, and when the scraping rod 30 moves in the scraping groove 22, a acting force can be provided for materials piled in the scraping groove 22. Because the humidity of the material entering the material conveying groove 21 is high and the viscosity is high, the acting force can drive the material accumulated in the material conveying groove 21 bonded with the material in the material scraping groove 22, so that the accumulated material in the material conveying groove 21 is separated from the material conveying groove 21, and then the accumulated material in the material conveying groove 21 can be cleaned in the process of rotating the valve core 20, the blanking valve is prevented from being blocked, and the production efficiency is improved.

In other words, the scraper groove 22 has a deeper depth than the delivery groove 21. This causes the scraper trough 22 to actually be formed by the bottom of the conveyor trough 21 continuing to be recessed downwardly at the portion where the conveyor trough 21 intersects the scraper trough 22, so as to prevent the scraper trough 22 itself from affecting the transport of the entire material.
Further, in the present embodiment, a gap is formed between the end of the scraper bar 30 facing one end of the valve core 20 and the bottom of the scraper groove 22, so as to prevent the scraper bar 30 from wearing the surface of the valve core 20.
In the present embodiment, the valve core 20 includes a rotating shaft 23 and a body portion 24 sleeved on the rotating shaft 23, the rotating shaft 23 is made of a stainless steel material, and the body portion 24 is made of a PTFE (Polytetrafluoroethylene) material. By making the body portion 24 entirely of PTFE material, the molding of the feed chute 21 and the scraper chute 22 is more easily achieved, and accumulation of material on the spool 20 is prevented.
In the present embodiment, as shown in fig. 1, the scraping bar 30 is disposed at the lower portion of the housing 10, so that the scraping bar 30 is closer to the discharge port 12, and the accumulation of materials in the housing 10 is prevented.
Further, along the rotation direction of the valve core 20, the valve core 20 is divided into a discharge side in the direction from the feed port 11 to the discharge port 12, and the valve core 20 is rotated from the reset side of the discharge port 12 to the feed port 11, and the scraper 30 is located at the reset side of the discharge port 12. As shown in fig. 1, the valve core 20 rotates in a counterclockwise direction, materials enter from the feed inlet 11, the left side of a parting line A-A in fig. 1 is a discharge side of the discharge port 12, and on the left side, a material conveying groove 21 receives the materials from the feed inlet 11 and conveys the materials to the discharge port 12, and most of the materials are discharged from the left side of the discharge port 12 under the action of a scraping rod 30; the right side of the dividing line A-A is the reset side of the discharge port, and a small part of materials are discharged on the reset side, and the material conveying groove 21 rotates from the position of the discharge port 12 to the position of the feed port 11 again. The scraper bar 30 is arranged on the side, so that the scraper bar 30 is prevented from influencing the transportation of materials.
Further, in the present embodiment, the housing 10 is formed with a through hole 13 into which the scraper bar 30 is inserted, and the scraper bar 30 is fixed to the housing 10 by a fixing member such as a nut.
Fig. 6 is a schematic side view of an anti-blocking blanking valve according to a second embodiment of the present utility model, and fig. 7 is a schematic structural diagram of a position adjusting plate in fig. 6. As shown in fig. 6 to 7, the anti-blocking blanking valve provided in the second embodiment of the present utility model is substantially the same as the first embodiment in that in this embodiment, a bar-shaped hole 14 connecting the inner and outer surfaces of the housing 10 is formed in the housing 10, the anti-blocking blanking valve further includes a position adjusting plate 15, a fixing hole 151 into which the scraper bar 30 is inserted is formed in the position adjusting plate 15, and a connecting hole 152 for connecting with the housing 10, and when the position adjusting plate 15 is fixed to the housing 10, the position adjusting plate 15 is blocked on the bar-shaped hole 14, and the position of the fixing hole 151 is different in a plurality of position adjusting plates 15. When the different position adjusting pieces 15 are fixed to the housing 10, the relative positions of the fixing holes 151 and the housing 10 are different. Fig. 7 shows two different position adjustment tabs 15 with different positions of the fixing hole 151.
In this embodiment, the position of the scraping bar 30 on the housing 10 can be adjusted by selecting different position adjusting pieces 15, so as to better enable the scraping bar 30 to scrape the valve core 20.
In summary, in the present utility model, when blanking is performed, the material may be first put into the housing 10 from the feed port 11, the material entering the housing 10 falls into the material conveying groove 21 of the valve core 20, and the material in the material conveying groove 21 is rotated to the discharge port 12 and flows out from the discharge port 12 along with the rotation of the valve core 20. Due to the arrangement of the scraper bar 30 and the scraper groove 22, the scraper bar 30 moves relative to the scraper groove 22 along with the rotation of the valve core 20. Since the scraping groove 22 is annularly arranged on the surface of the valve core 20, an intersecting area is formed between the scraping groove 22 and the material conveying groove 21, and when the scraping rod 30 moves in the scraping groove 22, a acting force can be provided for materials piled in the scraping groove 22. Because the humidity of the material entering the material conveying groove 21 is high and the viscosity is high, the actuator can drive the material accumulated in the material conveying groove 21 bonded with the material in the scraping groove 22, so that the accumulated material in the material conveying groove 21 is separated from the material conveying groove 21, and then the accumulated material in the material conveying groove 21 can be cleaned in the process of rotating the valve core 20, the blanking valve is prevented from being blocked, and the production efficiency is improved.
