The mouth of the bag is opened, so that the small bag of food at the discharge mechanism 32 can drop into the packaging bag 200, and the quantity of the small bag of food that hangs each time corresponds to the quantity that needs to be packaged in the packaging bag 200, and the bagging mechanism 31 will also The packed packaging bag 200 is transferred to the heat-sealing mechanism 34, and the bag opening of the packaging bag 200 is heat-sealed by the heat-sealing mechanism 34 to seal, thereby completing the whole sub-packaging operation. For ease of understanding, the front-back direction, left-right direction, and up-down direction involved in the present invention correspond to the longitudinal direction, lateral width direction, and vertical height direction of the rack A00 respectively, but are not limited thereto.

1 to 3, specifically, the first frame A01 has an inclined installation surface A011 for the belt conveyor mechanism 11 to be installed, and the second frame A02 has a first horizontal installation surface A021 for the distribution device 20 to be installed. , so that it is convenient for the distributing device 20 to accept the small bags of food falling from the raised belt conveyor mechanism 11, the third frame A03 has a second horizontal installation surface A031 for the dispensing device 30 to be installed, and the first horizontal installation The height of the surface A021 is higher than that of the second horizontal installation surface A031, so that the subpackaging device 30 can receive the small bags of food dropped by the fourth conveyor belt 24 from the lower side.

Referring to Fig. 3 to Fig. 6, specifically, the belt conveying mechanism 11 is installed on the inclined installation surface A011 of the first frame A01 through the support frame 13 arranged obliquely, and the material bin 12 is installed on the belt conveying mechanism 11, and the material bin 12 is an open bin with a relatively small lower end and a relatively large upper end, the relative lower end of the conveyor belt 111 of the belt conveyor mechanism 11 is placed in the material bin 12 to form an input end, and its relatively upper end Passes obliquely upwards away from the material bin 12 and is suspended on the top side of the first conveyor belt 21 to form an output end. Correspondingly, the material bin 12 has a penetration groove 12a for the conveyor belt 111 to pass through, and the penetration groove 12a is arranged on the bottom plate and the side plate of the material bin 12 . Wherein, the conveyor belt 111 is sleeved on the driving shaft 15 and the driven shaft 16 which are rotatably installed at the two opposite ends of the support frame 13, and driven by the motor 14 connected to the driving shaft 15, the driving shaft 15 and driven shaft 16 rotate, constantly the pouch food in the material bin 12 is conveyed toward the direction of distribution device 20 batch by batch.

Specifically, in some embodiments, the conveyor belt 111 of the belt conveyor mechanism 11 is evenly distributed with shifting plates 1111, and at least a small bag of food can be accommodated between adjacent shifting plates 1111, each shifting plate 1111 The specific height, width and distance between each other can be determined according to the size of the small bags of food, so as to effectively control the quantity of small bags of food conveyed batch by batch and realize smooth conveying operations. Among them, the number of small bags of food transported batch by batch is generally 1 bag, and occasionally there will be 2 stacked bags squeezed together and transported in the same batch. The two bags of small bags of food placed together have basically been dispersed during the falling and collision process, and the situation of incomplete dispersion rarely occurs, so that it is convenient to transfer one by one on the material distributing device 20 .

3 to 7, specifically, in some embodiments, the feeding device 10 further includes two first side plates 17 and two second side plates 18, and the two first side plates 17 are symmetrically arranged on the conveyor belt 111 The left and right opposite sides of the material bin 12 are located between the open end of the material bin 12 and the output end of the conveyor belt 111, thereby forming a closed-mouthed guide structure, thereby guiding and limiting the conveying direction of the small bag of food, and preventing the small bag of food from being conveyed While falling during the process, each batch of small bags of food is transported in a row on the conveyor belt 111, which is convenient for subsequent material distribution and packaging operations. The opposite upper side ends of the two second side plates 18 are connected to the two first side plates 17 in one-to-one correspondence, and the opposite lower side ends of the two are symmetrically suspended on the top side end of the first conveyor belt 21, and correspondingly have a The inner buckle 181 formed by bending in the direction of the other side, that is, the second side plate 18 is roughly in the shape of an obtuse "L", so as not only to stop and limit the falling direction of the small bag of food detached from the conveyor belt 111, but also to limit the falling direction of the small bag of food on the conveyor belt 111. During the falling process, a small number of stacked small bags of food play the role of breaking up.

Referring to Fig. 3 to Fig. 8, specifically, the first conveyor belt 21, the second conveyor belt 22, the third conveyor belt 23 and the fourth conveyor belt 24 all adopt endless belts, all of which can be rotatably installed on the two side plates of the mounting base 25 251, and connected with the first conveying motor 211, the second conveying motor 221, the third conveying motor 231 and the fourth conveying motor 241 in one-to-one correspondence, so as to rotate under the driving of the corresponding conveying motor. Wherein, the first conveyor belt 21 and the fourth conveyor belt 24 are arranged horizontally, and the height of the conveyor surface of the first conveyor belt 21 is higher than the height of the conveyor surface of the fourth conveyor belt 24, which is convenient for the incoming and outgoing of small bags of food. The second conveyor belt 22 and the third conveyor belt 23 are arranged obliquely, and the inclination angle of the conveying surface of the second conveyor belt 22 is much larger than the inclination angle of the conveying surface of the third conveyor belt 23, thereby respectively promoting and The drop with a certain height difference further expands the distance between each small bag of food and effectively improves the material distribution effect. Especially for very individual small bags of food that have not been completely dispersed on the first conveyor belt 21, the second conveyor belt 22 is lifted and dropped again to achieve complete separation, and the third conveyor belt 23 is passed through the smaller range. Lifting and falling can effectively expand the distance between each small bag of food, thereby improving the effect of material distribution. Further, a filling plate 212 is arranged in the gap between the butt ends of the first conveyor belt 21 and the second conveyor belt 22 to prevent the small bag of food from slipping from the gap or being stuck in the gap, resulting in ineffective transmission.

Specifically, in some embodiments, the running speeds of the conveyor belt 111, the first conveyor belt 21, the second conveyor belt 22, the third conveyor belt 23, and the fourth conveyor belt 24 can be different, so that each small bag of food can be effectively enlarged through different running speeds. The distance between them can realize smooth and efficient distributing operation. Specifically, the running speeds of the first conveyor belt 21 , the second conveyor belt 22 , the third conveyor belt 23 and the fourth conveyor belt 24 can be sequentially increased to enhance the separation effect. In addition, with regard to the conveying length, the conveying length of the second conveyor belt 22 is greater than the conveying length of the first conveying belt 21, but less than the conveying length of the third conveying belt 23, and the conveying length of the fourth conveying belt 24 is greater than or equal to that of the third conveying belt 23. The conveying length not only can achieve thorough material distribution, but also convey small bags of food more smoothly and evenly. And the inclination angle of the conveyor belt 111 is greater than the inclination angle of the second conveyor belt 22, its conveying length is relatively longer, and the lifting range is correspondingly larger, so the effect of the initial drop and material separation is obvious.

The adjustment plate 263 is obliquely and positionally adjustable between one of the two bent plates 262 and the connecting plate 261, thereby forming a A limiting channel, so that the small bag of food dropped from the conveying belt 111 first falls on the adjustment plate 263, and rebounds into the limiting channel by colliding with the adjusting plate 263. The completely separated small bags of food are broken up, so that each small bag of food slides down into the limiting channel one by one, and under the guidance of the limiting channel, it slides into the first conveyor belt 21 accurately, thereby further realizing the packaging of each small bag of food. Separation.
