Abstract
Description
Technical Field
[0001] This invention relates to packaging machinery, specifically to a material flattening device used in a cartoning machine. Background Technology
[0002] Currently, cartoning machines are used to integrate and package materials (such as blister packs), instructions (paper blister pack instructions), and cardboard boxes into small packaging boxes. These small packaging boxes are then integrated and packaged into medium-sized packaging boxes (i.e., boxes within boxes). This involves the primary and secondary packaging of various types of items such as food, medicine, and cosmetics, and has a large market demand.
[0003] These types of cardboard boxes are generally square and already opened. If the cardboard box is a novel flat sleeve box, it is a flat sleeve box with two-way openings (material usage instructions can be printed directly on its outer surface). The flat sleeve box needs to be expanded and opened first, the material edges flattened (any slight unevenness will prevent it from fitting), and then individual pieces of material can be placed inside. Multiple boxes can then be integrated into a medium-sized packaging box. This flat sleeve box does not require special instruction materials or a box-closing process, making it very convenient to use and destined for widespread application. Currently, the flat sleeve box is opened, pressed, and filled manually, resulting in low work efficiency and high labor intensity, which is not conducive to mass production applications. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a circulating lifting automatic material flattening device that automatically flattens the periphery of materials.
[0005] The objective of this invention is achieved through the following technical solution: a circulating lifting automatic material flattening device, comprising a pressing platform, on both sides of the pressing platform are respectively mounted a pressing main drive shaft and a pressing secondary drive shaft, on both sides of the pressing main drive shaft and the pressing secondary drive shaft are mounted a sprocket and chain assembly and a pressing track plate, on the pressing track plate are mounted a plurality of slide rail fixing blocks, and pressing blocks are mounted on the slide rail fixing blocks through pressing telescopic slide rods, and the pressing main drive shaft is connected to a pressing power source.
[0006] A material-pressing telescopic base plate is installed on the sprocket and chain assembly. The material-pressing telescopic slide rod passes through the material-pressing telescopic base plate, which is located between the material-pressing block and the slide rail fixing block. A telescopic linear bearing is installed on the material-pressing telescopic slide rod and at the material-pressing telescopic base plate. The material-pressing block has a "U" shaped structure.
[0007] With the structure of this invention, the sliding rail fixing block runs on the track groove of the pressing track plate, which drives the pressing block to descend and automatically and completely flatten the periphery of the material, making full preparation for the next step of pushing the material into the box. This improves production efficiency, reduces production and labor costs, and is conducive to large-scale production and wide application. It is especially suitable for the requirements of high-speed boxing and packaging. Attached Figure Description
[0008] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0009] Figure 1 This is a schematic diagram of the installation structure of the circulating lifting automatic material flattening device of the present invention.
[0010] Figure 2 This is a schematic diagram of a flat box and the material (single blister pack) being packaged together. Detailed Implementation
[0011] Reference Figure 1 As can be seen, the present invention applies to a circulating lifting automatic material flattening device for a cartoning machine, including a pressing platform 31 (one in front and one in back, one mounted on the main platform of the cartoning machine and the other on the outside). On both sides of the pressing platform 31, a pressing main drive shaft 34 (on the right side) and a pressing secondary drive shaft 36 (on the left side) are respectively mounted. On both sides of the pressing main drive shaft 34 and the pressing secondary drive shaft 36, there are two sprocket and chain assemblies 35 (circulating on the outside) and two pressing track plates 42 (on the inside). Several slide rail fixing blocks 40 are mounted on the pressing track plates 42. Pressing blocks 43 are mounted on the slide rail fixing blocks 40 through pressing telescopic slide rods 39 (two pieces). The pressing main drive shaft 34 is connected to the pressing power source 33 (a pressing drive motor mounted on a drive motor base 32).
[0012] A plurality of slide rail fixing blocks 40 are mounted on the pressing track plate 42 via cam bearings 41. The pressing track plate 42 has track grooves that allow the slide rail fixing blocks 40, pressing telescopic slide rods 39, and pressing blocks 43 to gradually rise or fall, and the cam bearings 41 slide on these track grooves. A pressing telescopic base plate 37 is mounted on the sprocket and chain assembly 35 (its chain). The pressing telescopic slide rod 39 passes through the pressing telescopic base plate 37, which is located between the pressing blocks 43 and the slide rail fixing blocks 40. Telescopic linear bearings 38 are mounted on the pressing telescopic slide rod 39 and at the pressing telescopic base plate, making the rising or falling process of the slide rail fixing blocks 40, pressing telescopic slide rods 39, and pressing blocks 43 smoother. The pressing blocks 43 have a "U"-shaped structure, which provides more comprehensive flattening of the material's perimeter. The pressing blocks 43 are located above the material compartment (used for placing materials) of the wraparound conveyor belt assembly of the material transport device. The slide rail fixing block 40, cam bearing 41, pressure material telescopic slide rod 39 (two pieces), pressure block 43, pressure material telescopic base plate 37, and telescopic linear bearing 38 (two pieces) are several sets of combinations.
[0013] The process of packaging the flat box 27 and the material 28 (single blister pack) involved in this invention is as follows: Figure 2 As shown in the attached diagram, this invention can be directly connected to an automatic cartoning machine (including a flat carton conveying device, a material conveying device, a flat carton transport device, and a material transport device). The working principle of this invention is as follows: the flat carton conveying device of the cartoning machine opens the flat carton bi-directionally, then conveys it and places it into the carton compartment of the rising circular conveyor belt assembly, while the flat carton remains open bi-directionally, and continues to be transported by the circular conveyor belt assembly; simultaneously, the material conveying device places the material into the material compartment of the rising circular conveyor belt assembly, and then continues to be transported by the circular conveyor belt assembly. At this time, the pressing power source 33 operates, driving the pressing main drive shaft 34 (on the right) and the pressing secondary drive shaft 36 (on the left) to rotate simultaneously. The sprocket and chain assembly 35 also rotates in a circular up-and-down cycle. Several slide rail fixing blocks 40 move simultaneously on the track groove of the pressing track plate 42 through cam bearings 41, and several pressing telescopic base plates 37 also move simultaneously with the sprocket and chain assembly 35. Thus, the pressing block 43 is gradually lowered by the up-and-down telescopic sliding rod 39. Finally, the "U"-shaped structure of the pressing block automatically and completely flattens the material around the material in the material compartment (and then gradually rises and rotates in a circular cycle), making full preparation for the next step of pushing the material into the box (completed by the material pushing device). The pressing block gradually descends from the leftmost position below the pressing arch, then flattens the material around the perimeter, and gradually rises from the rightmost position. When the pressing block is above the pressing arch, its height remains unchanged.
