[0022] The quantitative loading device 2 includes a quantitative material frame 11, a sealing plate 12, an adjusting side plate 13, a push-pull rod 14, a slot 15, a hole slot 16, a spring 17 and a clamping ball 18. The sealing plate 12 is fixedly connected to the quantitative material frame 11, the adjusting side plates 13 are symmetrically arranged on both sides of the quantitative material frame 11, the push-pull rod 14 is threadedly connected to the end of the adjusting side plate 13 away from the quantitative material frame 11, the slot 15 is evenly arranged at both ends of the top plate and the bottom plate of the adjusting side plate 13, eight hole slots 16 are arranged on the inner sides of both ends of the quantitative material frame 11, the spring 17 is embedded in the hole slot 16, and the clamping ball 18 is fixedly connected to the end of the spring 17 close to the adjusting side plate 13.

[0023] The top end of the quantitative material frame 11 is slidably connected to the bottom end of the material buffer bin 8, and the bottom end of the quantitative material frame 11 is slidably connected to the limiting slide groove 6, the top end of the sealing plate 12 is slidably connected to the bottom end of the material buffer bin 8, and the bottom end of the sealing plate 12 is slidably connected to the limiting slide groove 6, and the telescopic end of the electric push rod 7 is fixedly connected to one end of the quantitative material frame 11 close to the sealing plate 12.

[0024] The electric push rod 7 is connected to a controller via a wire, and the controller is fixedly connected to the bottom end of the limit plate 5. The controller is used to control the contraction of the electric push rod 7 to convey materials.

[0025] A leakage groove is formed at one end of the limiting plate 5 away from the electric push rod 7, and the top of the discharge barrel 10 is located directly below the leakage groove. When the quantitative material frame 11 moves to the top of the leakage groove, the material inside the quantitative material frame 11 falls into the discharge barrel 10 through the leakage groove.

[0026] The top end of the push-pull rod 14 is movably inserted into the bottom end of the top of the adjusting side plate 13, and the bottom threaded end of the push-pull rod 14 is threadedly connected to the bottom end of the adjusting side plate 13, so that the user can adjust the size of the internal space of the quantitative material frame 11 by pushing and pulling the adjusting side plate 13 through the push-pull rod 14, thereby adjusting the quantitative size of the material.

[0027] The clamping slot 15 and the clamping ball 18 match each other, and the clamping ball 18 is engaged in the clamping slot 15 at different positions, so as to adjust the internal space of the quantitative material frame 11.

[0028] Working principle: During use, first adjust the space inside the quantitative material frame 11 as needed, and pull the push-pull rod 14 through external force. The movement of the push-pull rod 14 drives the adjustment side plate 13 to move, and the movement of the adjustment side plate 13 drives the card slot 15 to move, thereby squeezing the card ball 18 to slide into the inside of the hole slot 16, and at the same time, the card ball 18 squeezes the spring 17 to contract. When the adjustment side plate 13 moves to the required position, the spring 17 rebounds and squeezes the card ball 18 into the inside of the card slot 15, so as to fix the adjustment side plate 13, and pour the material into the material buffer bin 8 through external force. At this time, the quantitative material frame 11 is located directly below the bottom end of the material buffer bin 8. The material in the material buffer bin 8 falls into the inside of the quantitative material frame 11 under the action of gravity, and then the controller controls the electric push rod 7 to extend, and the telescopic end of the electric push rod 7 pushes the quantitative material frame 11 to slide on the limit plate 5. The movement of 11 drives the sealing plate 12 to move. When the top of the quantitative material frame 11 is away from the bottom of the material buffer bin 8, the bottom of the material buffer bin 8 scrapes off the excess material at the top of the quantitative material frame 11, and the top of the sealing plate 12 is close to the bottom of the material buffer bin 8. When the quantitative material frame 11 is completely separated from the bottom of the material buffer bin 8, the top of the sealing plate 12 completely closes the bottom of the material buffer bin 8. At this time, the bottom end of the quantitative material frame 11 moves to the top of the discharge barrel 10, and the material inside the quantitative material frame 11 loses support and falls downward into the discharge barrel 10 under the action of gravity. When the bottom end of the quantitative material frame 11 is completely moved to the top of the discharge barrel 10, all the material inside the quantitative material frame 11 falls out. At this time, the electric push rod 7 begins to contract, and the telescopic end of the electric push rod 7 drives the quantitative material frame 11 to move to the bottom end of the material buffer bin 8 to continue loading, thereby realizing quantitative conveying of materials.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
