DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0027] As Figures 1 to 3 shown, an automatic feeding assembly, comprising a conveying frame 1, further comprising: a conveying belt assembly 2, the conveying belt assembly 2 is arranged on the conveying frame 1 and is used to convey dough; a material box 3, the material box 3 is arranged on the upper side of the conveying belt assembly 2 and is used to store flour, a plurality of uniformly distributed powder scattering holes 301 are formed in the bottom of the material box 3; and an auxiliary unloading mechanism, the auxiliary unloading mechanism is arranged in the material box 3, the auxiliary unloading mechanism comprises an ejector rod 401 used to block the powder scattering hole 301, a movable plate 4 fixedly arranged on the upper side of the ejector rod 401 and a driving part 5 used to drive the movable plate 4 to move, the driving part 5 is connected with the conveying belt assembly 2;

[0028] The conveying belt assembly 2 comprises a first conveying roller 201, a second conveying roller 202 rotatably connected to the conveying frame 1 and a conveying belt 203 arranged between the first conveying roller 201 and the second conveying roller 202, the first conveying roller 201 and the second conveying roller 202 are rotatably connected to the two ends of the conveying frame 1 respectively, the conveying frame 1 is provided with a conveying motor 204 used to drive the second conveying roller 202 to rotate, and the conveying motor 204 is provided with a zero reset program.

[0029] A bread forming machine comprises an automatic feeding assembly, and further comprises a forming device 12, and the end of the conveying frame 1 is arranged in the forming device 12 and connected with the forming device 12.

[0030] When the dough needs to be conveyed into the forming device 12, firstly, the conveying belt assembly 2 is controlled to operate, the conveying motor 204 drives the conveying roller to work with the conveying belt 203, so that the conveying belt assembly 2 works and drives the auxiliary discharging mechanism to act, the movable plate 4 drives the top rod 401 to move up and down frequently, the top rod 401 pushes the flour at the flour scattering hole 301, so that the flour scattering hole 301 is not blocked, the flour falls on the conveying belt 203, the dough is arranged on the flour, so that the dough is not adhered to the conveying belt 203, and the dough adhered with the flour enters the forming device 12 to be processed and formed, and when the equipment is stopped, namely when the conveying motor 204 stops working, the zero reset program is arranged in the conveying motor 204, the zero reset program is prior art, so that the output shaft of the conveying motor 204 drives the conveying roller to rotate by an initial angle, the top rod 401 reseals the flour scattering hole 301, so that the sealing property of the material box 3 is ensured, and the probability that the flour in the material box 3 is dampened is reduced.

[0031] As shown in Figure 3 , Figure 4 and Figure 5 , the driving member 5 comprises a rotating rod 501 rotatably connected to the conveying frame 1 and connected with the first conveying roller 201, a main bevel gear 502 arranged at the end of the rotating rod 501, a transmission rod 503 rotatably connected in the material box 3, and a secondary bevel gear 504 arranged at the lower side of the transmission rod 503 and engaged with the main bevel gear 502, the arc-shaped track strip 5031 is fixedly arranged on the transmission rod 503, the positioning rod 402 matched with the arc-shaped track strip 5031 is fixedly arranged on the movable plate 4, and the arc-shaped track strip 5031 is arranged between the two positioning rods 402.

[0032] When the first conveying roller 201 rotates, the rotating rod 501 is driven to rotate, the main bevel gear 502 at the end of the rotating rod 501 is engaged with the secondary bevel gear 504 for transmission, the secondary bevel gear 504 drives the transmission rod 503 to rotate, when the transmission rod 503 rotates, the arc-shaped track strip 5031 drives the movable plate 4 to move up and down reciprocatingly through the positioning rod 402, when the movable plate 4 drives the top rod 401 to move up, the top rod 401 no longer seals the flour scattering hole 301, the flour moves into the flour scattering hole 301 and falls on the conveying belt 203, and when the movable plate 4 drives the top rod 401 to move down, the top rod 401 pushes the flour arranged in the flour scattering hole 301, so that the flour falls on the conveying belt 203 smoothly.

[0033] As shown in Figure 3 and Figure 4As shown, the conveying frame 1 is fixed with an elastic expansion plate 6, the transmission rod 503 is rotatably connected with the movable end of the elastic expansion plate 6, the rotating rod 501 is provided as an expansion rod, the L-shaped plate 7 is rotatably connected with the transmission rod 503 at the end away from the rotating rod 501, and the cam 8 is fixed on the transmission rod 503 and movably abuts against the conveying frame 1;

[0034] When the transmission rod 503 rotates, the cam 8 abuts against the outer side wall of the conveying frame 1, cooperates with the elastic expansion plate 6, and makes the transmission rod 503 reciprocate left and right relative to the conveying frame 1, so that the flour falling at the flour scattering hole 301 is uniformly scattered on the conveying belt 203, avoiding that the flour is only concentratedly scattered on the lower side of the flour scattering hole 301, thereby ensuring the effect of the dough adhering to the flour and further ensuring the anti-sticking effect of the dough, and the expansion rod of the rotating rod 501 is composed of two rod bodies in key groove sliding, which facilitates the overall rotation of the rotating rod 501 with the conveying roller.

[0035] It should be noted that the cam 8 includes a protrusion 801 fixedly connected with the transmission rod 503 and a roller 802 rotatably connected with the protrusion 801 through a pin shaft; the cam 8 abuts against the side wall of the conveying frame 1 through the roller 802, which facilitates reducing the wear degree when the cam 8 abuts against the conveying frame 1 and ensures the service life.

[0036] As shown in Figure 1 and Figure 2 , the conveying frame 1 is provided with side baffles 9 on both sides of the conveying belt 203, and a scraping plate 901 is fixed between the two side baffles 9. Since the flour scattered by the material box 3 has a tendency to the left or right when it reciprocates, the side baffles 9 are arranged on both sides of the conveying belt 203 to block the flour scattered on the side edges of the conveying belt 203, avoiding the flour from being scattered in the area outside the conveying belt 203, which not only causes waste of flour but also makes it difficult to collect the flour; and the scraping plate 901 is arranged on the side baffle 9, which can uniformly scrape the flour scattered on the conveying belt 203, so that the flour is uniformly spread on the conveying belt 203, avoiding the situation of too much or too little flour, and ensuring the subsequent adhesion effect of the dough.

[0038] The scraper 10 arranged at the end of the conveying direction of the conveying belt 203 can scrape the flour on the conveying belt 203, so that the flour adhered to the dough by the subsequent conveying belt 203 moving to the lower side of the flour tank 3 again is not mixed with the newly falling flour, and the adhesion effect of the flour on the dough is not affected. The receiving plates 11 at both ends of the conveying frame 1 receive the flour scraped off by the scraping plate 901 and the flour scraped off by the scraper 10 respectively, and the flour is recycled and utilized.
