Description

Technical Field

[0001] This utility model relates to the technical field of filling equipment, and in particular to a horizontal bag feeding and packaging machine that can adapt to different bag widths. Background Technology

[0002] Horizontal bag packaging machines, as one of the core pieces of equipment in modern automated packaging production lines, are widely used in industries such as food, daily chemicals, pharmaceuticals, and chemicals. They are used to automatically open, fill, and seal pre-made bags. Their core workflow typically includes: bag picking, bag opening, material filling, sealing, and finished product output.

[0003] In existing technologies, horizontal bag-feeding packaging machines typically include a bag storage module (or bag warehouse, bag storage bin) for storing pre-made bags. The function of this module is to accommodate and orderly supply a certain number of pre-made bags. However, the commonly used bag storage modules have a significant technical drawback: their volume is usually fixed and cannot be adjusted. This means that the space inside the storage module to hold the bags is limited after design and manufacturing, and cannot be flexibly adjusted according to the actual dimensions of the pre-made bags used in production (especially the bag height and width). When packaging products of different sizes, it is often necessary to change to different bag sizes. At this time, the fixed-volume bag storage module cannot accommodate new bags that are too large or too small: if the bag is too large, it cannot be placed in the module or only a very small number can be placed, leading to frequent bag additions and reduced efficiency; if the bag is too small, it is too loose within the storage module, easily tipping over or misaligning, causing bag retrieval failure or bag jamming. Therefore, the fixed volume of existing bag storage modules severely limits the versatility and flexible production capabilities of the equipment, making it difficult for a single machine to efficiently adapt to the packaging needs of multiple varieties and small batches. Frequent replacement or adjustment of bag storage modules not only increases operational complexity but also brings additional downtime and costs.

[0004] On the other hand, another key problem commonly found in existing push rod mechanisms is the inability to adjust the spacing of existing push rod mechanisms, which is also a core bottleneck restricting the equipment from adapting to different bag sizes (especially bags of different widths). To adapt to different bag types, it is often necessary to replace the entire push rod mechanism or make cumbersome mechanical adjustments, which also leads to reduced equipment utilization, longer changeover times, and increased labor costs.

The bottom of the lower support plate 462 is slidably connected to the top of the bag clamping bottom plate 41, and the upper support plate 461 is slidably disposed on the top of the lower support plate 462. The adjustment drive source 463 is fixedly disposed on the bottom of the bag clamping bottom plate 41 and is used to drive the upper support plate 461 and the lower support plate 462 to perform translational movements in opposite directions.

[0058] In this embodiment, the clamp adjustment module 46 allows all first clamps 431 and second clamps 432 to be movable, thus adapting to bags without specific dimensions.

The opening and closing turntable 441-1 is fixedly installed at one end of the opening and closing linkage shaft 442-1, and the swing arm support 441-3 is fixedly installed on the working frame 1.

[0062] A pair of opening and closing swing arms 441-2 are respectively disposed below a pair of bag clamping bottom plates 41. The top of the opening and closing swing arms 441-2 is slidably connected to the bottom of the bag clamping bottom plate 41 via a guide rail and a slider. The guide rail is fixedly disposed at the bottom of the bag clamping bottom plate 41, and the slider is fixedly disposed at the top of the opening and closing swing arms 441-2 and slides along the guide rail.

The translation main gear 454 is fixedly mounted on the outer periphery of the translation shaft 452. The translation servo motor 451 drives the translation main gear 454 to rotate, thereby causing the translation shaft 452 to rotate. In this embodiment, the translation servo motor 451 is connected to the translation main gear 454 via gear transmission.

[0066] A pair of rotating arms 453 are respectively disposed below a pair of bag clamping bottom plates 41. Specifically, one end of the rotating arm 453 is fixedly connected to the outer periphery of the translation rotating shaft 452, and the other end of the rotating arm 453 is connected to the bottom of the bag clamping bottom plate 41 through a connecting arm.

[0067] In the initial state, the bag clamping plate 42 and the bag opening module 5 are vertically opposite each other.

[0068] During operation, the opening and closing servo motor 442-2 drives the opening and closing linkage shaft 442-1 to rotate, which in turn drives the opening and closing turntable 441-1 to rotate. The rotation of the opening and closing turntable 441-1 drives the swing arm to swing on the swing arm support 441-3, which in turn drives a pair of bag clamping bottom plates 41 to move closer or further away from each other.

[0069] The translation servo motor 451 drives the translation main gear 454 to rotate, which in turn drives the translation shaft 452 to rotate, which in turn drives the rotating arm 453 to rotate synchronously and, under the action of the connecting arm, drives the bag clamping bottom plate 41 to translate.

[0070] When taking out a bag: the pair of bag clamping bottom plates 41 open under the action of the opening and closing module 44. At this time, the pair of bag clamping plates 42 move away from each other. The pair of bag clamping bottom plates 41 move towards the bag storage module 2 under the action of the translation module 45 until the bag to be packaged is between the pair of bag clamping plates 42. Then the opening and closing module 44 drives the pair of bag clamping plates 42 to move closer to each other to clamp the bag. At the same time, the translation module 45 drives the pair of bag clamping plates 42 to return to the bottom of the bag opening module 5. The bag is clamped and opened by the bag opening module 5.

[0071] Bag movement: When a pair of bag clamping plates 42 are below the bag storage module 2, the first clamp 431 and the second clamp 432 clamp the bag located in the bag working channel 412, and sequentially move it to below the bag opening module 5, the filling module 6, and the sealing module 7 to complete the bag opening, filling, and sealing work. The sequential backward movement of the clamps in this embodiment is a well-known technology and will not be described here.

[0072] The translation and opening of the bag body in this device adopts a mechanical structure of gear-driven swing arm and rotating arm, which has the advantages of small space and stable and reliable effect.
