Therefore, this type of drop-type packing machine needs to strictly control the speed at which the materials are transported to the flap structure. Once the conveying speed is too fast, too much material may accumulate on the flap structure, affecting the normal packaging of the materials, such as causing errors in the number of materials to be packed.

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figure 1-3 As shown, this embodiment provides a drop-type boxing buffer mechanism, including three layers of telescopic buffer platforms distributed up and down, each layer of the telescopic buffer platform includes two sets of telescopic support components arranged oppositely, the telescopic support components include a telescopic drive device 3, a support plate 1 arranged at the output end of the telescopic drive device, and the buffer platform on the top layer is provided with a counting sensor 2 on its feeding side. The telescopic drive device can generally use a cylinder, and since this mechanism generally needs to be used in conjunction with a conveying mechanism, the counting sensor 2 can be arranged on the conveying mechanism, and the counting sensor 2 is aligned between the conveying mechanism and this mechanism. The working principle of this embodiment is as follows: the material is transported from the conveying mechanism to the buffer mechanism in sequence. When the material passes between the two mechanisms, it is identified and counted by the counting sensor 2 until the required amount of material enters the first buffer platform (the highest layer). At this time, the first buffer platform is opened, and all the materials fall to the second buffer platform. The first buffer platform is closed, and the first buffer platform can continue to receive materials; then the second buffer platform is opened, and the material falls to the third buffer platform. After the second buffer platform is closed, the material can be received again; finally, the third buffer platform is opened, and the material falls into the packaging box below, and the third buffer platform is closed. In this way, compared with the conventional drop-type cartoning machine, in addition to the third buffer platform that directly cooperates with the packaging box, this embodiment also adds the upper two buffer platforms, so that when the material interval on the conveying mechanism changes, that is, when the speed at which the material reaches this mechanism changes, the material can be temporarily stored through the upper two buffer platforms to ensure the stable cooperation between the third buffer platform and the packaging box below, and avoid the situation where the packaging box is too late to receive the material.

[0031] like Figure 4 As shown, the telescopic driving device 3 includes a device body 31, a cylinder 32 disposed in the middle of the device body, two guide rods 33 disposed on both sides of the cylinder 32, and a connecting plate 34 disposed at the ends of the cylinder 32 and the two guide rods 33, and the connecting plate 34 is connected to the support plate 1. Of course, the two guide rods 33 are telescopically connected to the device body 31, and the two guide rods 33 not only play a guiding role on the support plate 1, but also reduce the supporting pressure of the cylinder 32, thereby ensuring the service life of the cylinder.

[0032] In order to ensure that the material can fall down stably and accurately, a falling channel is provided between the two sets of telescopic support components, and the falling channel is surrounded by two left and right vertical plates 41 and two front and rear baffles 42. The vertical plates 41 are arranged in the telescopic direction of the support plate 1. Correspondingly, Figure 6 As shown, the vertical plate 41 is provided with a telescopic slot 411 for the support plate 1 to be telescopic. In order to further improve the stability of the support plate telescopic, two guide blocks 412 are provided in the telescopic slot 411, and the support plate 1 is provided with two guide slots 11 that match the guide blocks 412 to guide the support plate. However, directly opening such a small telescopic slot on the vertical plate has high processing requirements, so in order to simplify the processing technology, such as Figure 5 As shown, the vertical plate 41 includes three unit plates 4101 which are spliced ​​in sequence from top to bottom, and a bottom plate 43 is also provided under the entire vertical plate. The expansion groove 411 is formed between adjacent unit plates 4101 and between the lowest unit plate and the bottom plate 43, and the three unit plates can maintain a gap between each other, i.e., the expansion groove, by fixed connection with the front and rear baffles 42 or other structures. In order to improve the accuracy of the splicing relationship between the unit plates 4101 and between the unit plates and the base plate 43, mutually matching positioning grooves 401 and guide blocks 412 are provided between adjacent unit plates 4101 and between the unit plates and the base plate 43; specifically, two positioning grooves 401 are provided on the base plate 43, and two guide blocks 412 are provided at the lower end of each unit plate 4101, and two positioning grooves 401 are provided at the upper ends of the two unit plates below, and the accuracy of the splicing position is ensured by inserting the guide blocks 412 into the positioning grooves 401. At the same time, since the unit plates are fixed by front and rear baffles or other structures, the guide blocks 412 do not need to be fully inserted into the positioning grooves 401 to obtain support.

[0033] In order to obtain the material information in the second and third buffer platforms, material sensors 5 are provided at both buffer platforms. Since the materials on the upper layer are all dropped at once and the counting of the materials has been completed on the first layer, the material sensors 5 on the second and third layers do not need to count, but only need to sense whether there is material, and when sensing that there is material on the upper layer but not on the lower layer, the support plate on the upper layer is opened. The material sensor 5 is specifically installed on the baffle 42 close to the side of the conveying mechanism, and a sensing port is provided on the baffle 42 on this side, so that the material sensor can obtain the internal material information without being affected by the material.

[0034] like Figure 7 and 8 As shown, the utility model also provides a drop-type packing machine, including a frame 6, a conveying mechanism 7, and a drop-type packing buffer mechanism as described above, wherein the conveying mechanism 7 is arranged on the frame 6, and the drop-type packing buffer mechanism is arranged at the discharge end of the conveying mechanism 7. Specifically, the conveying mechanism 7 is a belt conveyor, and a support frame 61 is arranged on the discharge side of the frame 6 for installing the buffer mechanism. In order to allow the material to be transported in a straight line so as to accurately pass through the detection position of the counting sensor 2, the conveying mechanism 7 is inclined to one side, and a limit plate 8 is arranged on the lower side, so that the material can be transported in a straight line close to the limit plate 8 under the action of gravity, and the counting sensor can be arranged on the limit plate 8 through a bracket.

[0035] The above is only a preferred specific implementation of the utility model, which is a realization method based on the overall concept of the utility model, and the protection scope of the utility model is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
