[0031] Please combine Figures 1 to 3As shown, the utility model proposes a feeding device 100, which is used for transporting glass powder raw materials. The feeding device 100 includes a conveyor 1, a scraper assembly 2 and a pushing device 3. The conveyor 1 is provided with a conveyor belt 12, and the conveyor belt 12 forms a conveying channel 13. The conveying channel 13 has an outlet 131, and the conveying channel 13 is used to transport raw materials; the scraper assembly 2 is adjustably connected to the conveyor 1, and the scraper assembly 2 is provided with a scraper 23, and the scraper 23 is arranged corresponding to the outlet 131 and abuts against the conveyor belt 12; the pushing device 3 includes a pushing frame 31, The pushing drive member 32 and the pushing plate 33, the pushing frame 31 is connected to the conveying device 1, the pushing frame 31 is provided with a pushing groove 311 and a feed port 312 and a discharge port 313 connected to the pushing groove 311, the feed port 312 is arranged corresponding to the outlet 131, the discharge port 313 is used to deliver the raw materials, the pushing drive member 32 is connected to the pushing frame 31, and the pushing plate 33 is connected to the output end of the pushing drive member 32; wherein, the pushing drive member 32 drives the pushing plate 33 to move back and forth along the pushing groove 311 to push the raw materials in the pushing groove 311 out of the discharge port 313.

[0032] In this embodiment, the feeding device 100 is composed of a conveying device 1, a scraper assembly 2 and a pushing device 3. The conveying device 1 forms a conveying channel 13 to realize the transportation of glass raw materials. It can be understood that the two ends of the conveying channel 13 have an inlet and an outlet 131 respectively for the entry and exit of glass raw materials. The scraper 23 in the scraper assembly 2 is set corresponding to the outlet 131, and the feed port 312 of the pushing trough 311 is also set corresponding to the outlet 131. In this way, the raw materials in the conveying channel 13 can enter the pushing trough 311 from the outlet 131 through the feed port 312 or directly enter the mixing device. At the same time, the scraper 23 will scrape the residual raw materials on the conveyor belt 12, and the residual raw materials will also enter the pushing trough 311 from the feed port 312 of the pushing trough 311, thereby reducing the residual raw material powder during the conveying process. The scraper assembly 2 and the conveying device 1 are adjustable and connected. , to adjust the distance between the scraper 23 and the conveying channel 13, to ensure that the scraper 23 can scrape the powder in the conveying channel 13.

This effectively reduces the loss of raw materials during transportation, reduces the error between the weighed weight of the raw materials and the actual mass involved in glass production, improves the high-precision batching of float glass, and thus improves the production quality of glass.

[0033] In actual implementation, the pusher device 3 also includes a controller, which is connected to the signal of the conveyor device 1 and the pusher drive 32.

By adjusting the tensioning member 22, the distance between the fixed shaft 21 and the conveying device 1 can be adjusted, and then the degree of contact between the scraper 23 and the conveyor belt 12 can be adjusted to improve the scraping effect of the scraper 23.

[0036] It can be understood that the tensioner 22 and the scraper 23 can be set on the same side of the fixed shaft 21. At this time, the more the tensioner 22 contracts, the closer the scraper 23 is to the conveyor belt 12, and the more the tensioner 22 stretches, the less tightly the scraper 23 abuts against the conveyor belt 12. The tensioner 22 and the scraper 23 can also be set on different sides of the fixed shaft 21, which is not specifically limited here.

[0037] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the tensioning member 22 includes a mounting member, a screw rod 223, a nut 224 and an elastic member 225.

It can be understood that the conveying device 1 is provided with a mounting base, the mounting base is provided with an opening, one end of the screw 223 is inserted into the opening, the nut 224 is sleeved on the portion of the screw 223 passing through the opening, the elastic member 225 is sleeved on the portion of the screw 223 located between the opening and the mounting member, and the elastic member 225 is kept in a compressed state, so that the screw 223 is lifted and lowered in the opening by tightening or loosening the nut 224, and then the screw 223 drives the mounting member and the fixed shaft 21 to move, so that the close contact between the scraper 23 and the conveyor belt 12 is reduced or increased, and the two ends of the elastic member 225 abut against the mounting base and the mounting member, so that the mounting member and the fixed shaft 21 remain stable during the lifting process.

[0039] In one embodiment of the present invention, Figure 2 As shown, the mounting member includes a mounting seat 221 and a mounting plate 222, the mounting plate 222 and the mounting seat 221 are spaced apart on the fixed shaft 21, the mounting seat 221 is provided with a first mounting hole 2211, and the mounting plate 222 is provided with a second mounting hole 2221; the screw rod 223 includes a main body section 2231 and a connecting section 2232 connected at an angle, the main body section 2231 is passed through the first mounting hole 2211, the nut 224 and the elastic member 225 are sleeved on the main body section 2231, the connecting section 2232 is passed through the second mounting hole 2221 and is connected to the mounting plate 222, the plane where the first mounting hole 2211 is located is parallel to the axial direction of the fixed shaft 21, and the plane where the second mounting hole 2221 is located is perpendicular to the axial direction of the fixed shaft 21.

[0040] In this embodiment, the mounting member is composed of a mounting seat 221 and a mounting plate 222. The mounting plate 222 and the mounting seat 221 are respectively connected to the main section 2231 and the connecting section 2232 of the screw 223. The main section 2231 and the connecting section 2232 are connected at an angle, so as to achieve the limitation of the screw 223 in two directions and improve the stability of the lifting of the screw 223. It can be understood that the elastic member 225 is sleeved on the main section 2231 and abuts against the mounting seat 221, so as to ensure that the positions of the mounting seat 221 and the fixed shaft 21 remain unchanged when the nut 224 does not rotate. Optionally, the mounting plate 222 is fixedly connected to the fixed shaft 21, the mounting seat 221 is sleeved on the fixed shaft 21, and the second mounting hole 2221 can be set in multiple numbers along the circumferential direction of the fixed shaft 21, so that the screw 223 can be set on different sides of the fixed shaft 21 to adapt to different application scenarios.

Optionally, the connecting plate 211 is connected to the fixed shaft 21 by welding, and bolts pass through the connecting holes 212 of the connecting plate 211 and the through holes of the scraper 23, so that the scraper 23 and the connecting plate 211 are detachably connected, so as to facilitate the replacement of the scraper 23. The setting of the connecting plate 211 avoids the scraper 23 being directly connected to the fixed shaft 21, which increases the difficulty of installing the scraper 23. It can be understood that the connecting plate 211 and the scraper 23 can both be arranged in a plate shape, and the connecting hole 212 and the through hole are easy to align, so as to reduce the difficulty of installing the scraper 23.
