[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 4 A quantitative feeding device comprises a feeding tank 1, an opening and closing component 2 is arranged below the feeding tank 1, and the opening and closing component 2 is used to control the opening and closing of the feeding tank 1. The opening and closing component 2 comprises an air bag 201 arranged below the feeding tank 1, and the outer wall of the air bag 201 is connected to a connecting plate 202, and a quantitative barrel 203 is arranged directly below the feeding tank 1, and one end of the connecting plate 202 extends to the interior of the quantitative barrel 203, and the connecting plate 202 is rotatably connected to the quantitative barrel 203, and the inner wall of the connecting plate 202 is rotatably connected to a fixing rod 204, and a sealing cover 205 is fixedly installed on the top of the fixing rod 204, and the sealing cover 205 is located inside the feeding tank 1 and is slidably connected to the inner wall of the feeding tank 1.

[0025] The airbag 201 is expanded or contracted by retracting and releasing the gas in the airbag 201. First, due to the sliding connection between the sealing cover 205 and the discharge tank 1, the connecting plate 202 is in a parallel state. When the airbag 201 expands, it squeezes one end of the connecting plate 202, so that the end of the connecting plate 202 located outside the quantitative barrel 203 moves downward, and then the end of the connecting plate 202 located inside the quantitative barrel 203 drives the fixing rod 204 and the sealing cover 205 to move upward;

[0026] When the sealing cover 205 moves upward away from the relatively narrow passage at the bottom of the material tank 1, the sealing cover 205 will enter the relatively spacious area in the material tank 1, and then the outer wall of the sealing cover 205 will no longer contact the inner wall of the material tank 1. At this time, the material in the material tank 1 will flow into the quantitative barrel 203 along the gap between the sealing cover 205 and the material tank 1. The capacity of the quantitative barrel 203 is set in advance according to a specific capacity;

[0027] When the material fills the quantitative barrel 203, the material is in a measured amount. At this time, the gas in the airbag 201 is extracted, and the airbag 201 will pull the connecting plate 202 to a parallel state, so that the sealing cover 205 returns to the narrower area at the bottom of the discharge tank 1, and then a specific amount of material in the quantitative barrel 203 can be released.

[0028] See also Figure 1-Figure 3 A discharge box 3 is arranged below the discharge tank 1, the bottom end of the discharge tank 1 is located inside the metering barrel 203, the outer wall of the discharge tank 1 is fixedly connected to the top of the discharge box 3, the opening and closing assembly 2 is located inside the discharge box 3, the metering barrel 203 is fixedly installed on the inner wall of the discharge box 3, the outer wall of the airbag 201 is fixedly connected to the inner top wall of the discharge box 3, the discharge tank 1 is communicated with the metering barrel 203, and a cone 4 is fixedly installed on the top of the sealing cover 205.

[0029] The discharge box 3 is used to support the opening and closing component 2. At the same time, the discharge box 3 also fixes and supports the discharge tank 1, so that the opening and closing component 2 is connected with the discharge tank 1, which is convenient for the opening and closing component 2 to control the opening and closing of the discharge tank 1. The discharge tank 1 is connected with the metering barrel 203, which is convenient for the material in the discharge tank 1 to enter the metering barrel 203. The cone 4 can reduce the resistance of the sealing cover 205 to move upward, so that the sealing cover 205 can be moved upward more easily.

[0030] See also Figure 2 A fixed block 7 is fixedly installed on the top of the unloading box 3, an air pump 5 is fixedly installed on the top of the fixed block 7, an air pipe 6 is connected between the air pump 5 and the air bag 201, and the air pipe 6 is plugged into the unloading box 3.

[0031] The fixing block 7 fixes the air pump 5 on the top of the unloading box 3. The air pump 5 is used to evacuate and inflate the airbag 201 so that the airbag 201 can expand or contract freely. The air pipe 6 is used to connect the airbag 201 and the air pump 5 together.

[0032] See also Figure 4 The metering barrel 203 is provided with a through slot 8, a rotating rod 9 is fixedly installed on the inner wall of the through slot 8, the connecting plate 202 is rotatably connected to the outer wall of the rotating rod 9, a part of the connecting plate 202 is located inside the through slot 8, and the inner bottom wall and the inner top wall of the through slot 8 are both installed with elastic cloth 10, and the end of the elastic cloth 10 away from the through slot 8 is connected to the outer wall of the connecting plate 202.

[0033] The through groove 8 provides a swinging space for the connecting plate 202. Since the through groove 8 is left between the connecting plate 202 and the quantitative barrel 203, in order to prevent the material in the quantitative barrel 203 from flowing out of the through groove 8, the through groove 8 is blocked by the elastic cloth 10. The elastic cloth 10 can not only prevent the material from flowing out of the through groove 8, but also the connecting plate 202 can squeeze the elastic cloth 10 when the connecting plate 202 swings. The elastic cloth 10 itself is elastic, so the elastic cloth 10 will not affect the swinging of the connecting plate 202. The rotating rod 9 supports the connecting plate 202 so that the connecting plate 202 can rotate along the outer wall of the rotating rod 9 when it swings.

[0034] Embodiment 2:

[0035] See also Figure 1 and Figure 3 The metering barrel 203 is provided with a discharge port 15, a mounting rod 11 is fixedly installed at the bottom of the connecting plate 202, a trapezoidal extrusion block 12 is fixedly installed at the bottom of the mounting rod 11, a baffle 14 is arranged below the discharge port 15, the discharge port 15 is fixedly connected between the baffle 14 and the inner wall of the discharge box 3, a trapezoidal resistance block 13 is fixedly installed on the outer wall of the baffle 14, and the inclined surface of the trapezoidal extrusion block 12 is against the inclined surface of the trapezoidal resistance block 13.

[0036] When the end of the connecting plate 202 located outside the quantitative barrel 203 moves downward, it will drive the mounting rod 11 to move downward, and when the mounting rod 11 moves downward, it will drive the discharge port 15 to move downward together, and when the discharge port 15 moves downward, it will squeeze the trapezoidal resistance block 13, so that the trapezoidal resistance block 13 moves toward the quantitative barrel 203;

[0037] The trapezoidal abutment block 13 will drive the baffle plate 14 to move closer to the discharge port 15 when it moves horizontally, and the discharge port 15 will be blocked by the discharge port 15 to prevent the material in the quantitative barrel 203 from flowing out of the discharge port 15 before it is full. At the same time, the narrower area at the bottom of the discharge tank 1 is longer, so when the sealing cover 205 completely enters the wider area in the discharge tank 1, the baffle plate 14 has already blocked the discharge port 15;

[0038] When the sealing cover 205 blocks the discharge tank 1, the baffle 14 will slowly leave the discharge port 15, facilitating the outflow of the material in the metering barrel 203. The discharge port 15 can pull the baffle 14 back to its original position after the trapezoidal extrusion block 12 rises. Since the distance between the sealing cover 205 and the narrow area of ​​the discharge tank 1 is shorter, the baffle 14 will slowly expose a small part of the discharge port 15 after the sealing cover 205 blocks the discharge tank 1. Moreover, the area of ​​the baffle 14 is larger than the discharge port 15. Therefore, the discharge port 15 will not be exposed immediately when the baffle 14 moves a short distance, so as to prevent the material in the metering barrel 203 from starting to flow out of the discharge port 15 before the sealing cover 205 blocks the discharge tank 1.

[0039] See also Figure 1 and Figure 3 Two guide rods 16 are fixedly installed on the inner wall of the unloading box 3, the baffle 14 is slidably connected to the outer wall of the guide rod 16, and the baffle 14 is in close contact with the discharge port 15.

[0040] The guide rod 16 supports the baffle 14 so that the baffle 14 can slide along the outer wall of the guide rod 16 when moving. The guide rod 16 makes the baffle 14 more load-bearing so that the material in the metering barrel 203 will not be pressed to fall or loosen after falling to the top of the baffle 14.

[0041] Working principle:

[0042] The airbag 201 is expanded or contracted by retracting and releasing the gas in the airbag 201. First, due to the sliding connection between the sealing cover 205 and the discharge tank 1, the connecting plate 202 is in a parallel state. When the airbag 201 expands, it squeezes one end of the connecting plate 202, so that the end of the connecting plate 202 located outside the quantitative barrel 203 moves downward, and then the end of the connecting plate 202 located inside the quantitative barrel 203 drives the fixing rod 204 and the sealing cover 205 to move upward;

[0043] When the sealing cover 205 moves upward away from the relatively narrow passage at the bottom of the material tank 1, the sealing cover 205 will enter the relatively spacious area in the material tank 1, and then the outer wall of the sealing cover 205 will no longer contact the inner wall of the material tank 1. At this time, the material in the material tank 1 will flow into the quantitative barrel 203 along the gap between the sealing cover 205 and the material tank 1. The capacity of the quantitative barrel 203 is set in advance according to a specific capacity;

[0044] When the material fills the quantitative barrel 203, the material is in a measured amount. At this time, the gas in the airbag 201 is extracted, and the airbag 201 will pull the connecting plate 202 to a parallel state, so that the sealing cover 205 returns to the narrower area at the bottom of the discharge tank 1, and then a specific amount of material in the quantitative barrel 203 can be released.

[0045] When the end of the connecting plate 202 located outside the quantitative barrel 203 moves downward, it will drive the mounting rod 11 to move downward, and when the mounting rod 11 moves downward, it will drive the discharge port 15 to move downward together, and when the discharge port 15 moves downward, it will squeeze the trapezoidal resistance block 13, so that the trapezoidal resistance block 13 moves toward the quantitative barrel 203;

[0046] The trapezoidal abutment block 13 will drive the baffle plate 14 to move closer to the discharge port 15 when it moves horizontally, and the discharge port 15 will be blocked by the discharge port 15 to prevent the material in the quantitative barrel 203 from flowing out of the discharge port 15 before it is full. At the same time, the narrower area at the bottom of the discharge tank 1 is longer, so when the sealing cover 205 completely enters the wider area in the discharge tank 1, the baffle plate 14 has already blocked the discharge port 15;

[0047] When the sealing cover 205 blocks the discharge tank 1, the baffle 14 will slowly leave the discharge port 15, facilitating the outflow of the material in the metering barrel 203. The discharge port 15 can pull the baffle 14 back to its original position after the trapezoidal extrusion block 12 rises. Since the distance between the sealing cover 205 and the narrow area of ​​the discharge tank 1 is shorter, the baffle 14 will slowly expose a small part of the discharge port 15 after the sealing cover 205 blocks the discharge tank 1. Moreover, the area of ​​the baffle 14 is larger than the discharge port 15. Therefore, the discharge port 15 will not be exposed immediately when the baffle 14 moves a short distance, so as to prevent the material in the metering barrel 203 from starting to flow out of the discharge port 15 before the sealing cover 205 blocks the discharge tank 1.
