Specific embodiments

[0025] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail through specific embodiments.

[0026] As Figure 1 shown, the present utility model provides a precise food weighing and packing machine, including a chassis 1, a belt conveyor 2 arranged on the inner top of the chassis 1, a controller 3 locked and fixed on the side surface of the chassis 1. A support frame 4 is installed at the edge of the top surface of the chassis 1, and a hopper 5 located above the belt conveyor 2 is installed at the top of the support frame 4. The hopper 5 is used for pre - storing the food to be weighed and packed;

[0027] As Figures 2 to 4 shown, in this embodiment, it further includes a transfer mechanism 6 arranged at the bottom of the hopper 5. The transfer mechanism 6 includes a connecting pipe 61 arranged at the bottom of the hopper 5;

[0028] At the front and rear ends of the inner top of the connecting pipe 61, a guiding block 62 is installed at each end. The guiding block 62 is used to guide and convey the food into the feeding trough 65. Between the front and rear opposite surfaces of the two guiding blocks 62, a feeding roller 63 is arranged. The front and rear ends of the feeding roller 63 are respectively in contact with the two guiding blocks 62, and the feeding roller 63 is rotationally connected to the inside of the connecting pipe 61 through a rotating shaft 64;

[0029] A plurality of feeding troughs 65 for transferring the food are evenly arranged in the circumferential direction on the outer wall of the feeding roller 63. A weighing mechanism is arranged below the feeding roller 63 for weighing the packed food;

[0030] The rotating shaft 64 is connected to the output shaft of a motor 66 installed on the connecting pipe 61. The motor 66 provides driving force for the rotating shaft 64 to drive the feeding roller 63 to rotate synchronously to convey the food;

[0031] The motor 66 is electrically connected to the controller 3;

[0032] Wherein, there is a spacing between the connecting pipe 61 and the top surface of the belt conveyor 2 to facilitate the movement of the packaging box between the connecting pipe 61 and the belt conveyor 2;

[0033] In this embodiment, an arc-shaped groove is formed at one end of the guide block 62 close to the feeding roller 63, and the inner side of the arc-shaped groove is in contact with the side surface of the feeding roller 63. The feeding roller 63 is limited through the arc-shaped groove to prevent the food in the feeding groove 65 from falling off;

[0034] In this embodiment, the top surface of the guide block 62 extends obliquely downward in the direction towards one end of the feeding roller 63, facilitating the sliding of the food on the guide block 62 into the feeding groove 65;

[0035] In this embodiment, a number of adjusting plates 67 are installed inside the feeding groove 65, and the adjusting plates 67 are flush with the side surface of the feeding groove 65, facilitating the adjustment of the actual food accommodation space in the feeding groove 65 by installing adjusting plates 67 of different thicknesses, so as to adjust the amount of food conveyed each time;

[0036] In this embodiment, the weighing mechanism includes a movable frame 68 rotatably installed in the connecting pipe 61 and located below the feeding roller 63, a driving cylinder 611 rotatably installed in the connecting pipe 61, a support plate 69 movably installed inside the movable frame 68, the support plate 69 can move up and down along the inner side of the movable frame 68, a weighing sensor 610 locked and fixed at the bottom inside the movable frame 68 and connected to the support plate 69. The weighing sensor 610 is used to weigh the food on the support plate 69 to more accurately control the amount of food falling into the packaging box;

[0037] The top piston rod of the driving cylinder 611 is rotatably connected to the bottom of the movable frame 68, and when the piston rod of the driving cylinder 611 is fully extended, the movable frame 68 rotates to a horizontal state. The weighing sensor 610 is electrically connected to the controller 3;

[0038] Wherein, the support plate 69 is flush with the top surface of the movable frame 68, facilitating the sliding discharge of the food on the support plate 69 and the top of the movable frame 68;

[0039] Wherein, one weighing sensor 610 is installed at each of the left and right ends of the bottom inside the movable frame 68, and the two weighing sensors 610 are respectively connected to the left and right ends of the bottom of the support plate 69, facilitating the more accurate weighing of the food on the support plate 69 through the two weighing sensors 610;

[0040] Specifically, during use, starting the motor 66 drives the rotating shaft 64 and the feeding roller 63 to rotate. The feeding roller 63 drives the feeding chute 65 to rotate. The food in the hopper 5 slides into the inner side of the feeding chute 65 with the opening facing upward. As the feeding roller 63 rotates, when the feeding chute 65 with the opening facing upward rotates to have the opening facing downward, the food inside it drops onto the support plate 69. The food on the support plate 69 is weighed by the weighing sensor 610. When the weight of the food reaches the preset value, the controller 3 controls the motor 66 to stop working. At this time, the feeding chute 65 no longer conveys food, making the amount of food on the support plate 69 more accurate. Then, the driving cylinder 611 is controlled to drive the movable frame 68 to rotate downward. The movable frame 68 drives the support plate 69 to rotate to an inclined state and form a gap with the inner wall of the connecting pipe 61. The food drops downward through the gap onto the belt conveyor 2, and then the belt conveyor 2 transports the food into the packaging box at the preset value at the end of the belt conveyor 2 to complete the weighing and packaging work of the food.
