Abstract
Description
Technical Field
[0001] This utility model relates to the field of square bottom valve bag technology, specifically a valve bag packing and collecting device. Background Technology
[0002] The valve bag packing and collecting device is an important device used in the valve bag manufacturing and assembly process. It is mainly used to pack several assembled valve bags into bags. Through its automated, efficient and multifunctional design, it meets the strict requirements of modern industrial production for packaging efficiency and quality.
[0003] Chinese patent CN220663139U discloses a device for packaging and collecting valve bags, including a main frame with a first electro-hydraulic rod fixedly connected to the lower surface of the upper end of the main frame. The beneficial effect of this invention is that the square-bottomed valve bag is conveyed by a first conveyor belt, allowing the front half of the bag to enter a receiving plate. The movement of the sliding end of the screw slide causes a folding tube to descend between the first conveyor belt and the receiving plate. This descent folds the middle of the square-bottomed valve bag between the first conveyor belt and the receiving plate. The extension of the telescopic end of the second electro-hydraulic rod causes a second flattening device to roll the folded square-bottomed valve bag on the second conveyor belt, compacting the folded area and preventing the bag from unfolding. The folded square-bottomed valve bag is then transferred via the second conveyor belt, eliminating the need for manual folding and improving processing efficiency.
[0004] The above-mentioned device has an automatic folding effect, but when the existing device packs the valve bags, there will be problems such as several valve bags not being stacked neatly, making it difficult to pack after compression and damaging the product. At the same time, a valve bag packing and collecting device is needed during the packing process. Utility Model Content
[0005] The purpose of this invention is to provide a valve bag packing and collecting device to solve the problem that when existing devices pack valve bags, several valve bags may not be stacked neatly, making them difficult to pack after compression and causing product damage.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve bag packing and collecting device, comprising a workbench, a hydraulic cylinder fixedly mounted on the workbench, a pressure plate fixedly mounted on the output end of the hydraulic cylinder, and a flattening mechanism provided on one side of the workbench; the flattening mechanism includes a pressure seat, the pressure seat fixedly mounted on the lower side of the workbench, a rotating seat fixedly mounted on the upper part of the pressure seat, a baffle rotatably mounted on the rotating seat, two buffer springs fixedly mounted side-by-side between the baffle and the workbench, two sliding blocks slidably mounted side-by-side inside the pressure seat, a protective plate fixedly mounted on each of the two sliding blocks, and an adjusting bolt threaded onto the pressure seat through the protective plates on both sides.
[0007] Preferably, both the pressure plate and the pressure seat have two square grooves arranged side by side, and the guard plate is adapted to the square grooves.
[0008] Preferably, the adjusting bolt has an annular groove in the middle, and a block is fixedly installed on the lower part of the pressure seat, with the block fitting onto the annular groove.
[0009] Preferably, a bag-collecting mechanism is provided on the workbench. The bag-collecting mechanism includes an electric telescopic rod, which is fixedly installed on the workbench. A fixed seat is fixedly installed on the output end of the electric telescopic rod. Three upper roller shafts are rotatably installed on the fixed seat. A first gear is fixedly installed at both ends of the three upper roller shafts. A second gear is meshed between two of the first gears. A drive motor is installed on one of the second gears. Several lower roller shafts are rotatably installed on the lower part of the workbench. A first support plate is fixedly installed at the lower part of one side of the workbench. A second support plate is slidably installed at the middle part of one side of the workbench. Two support springs are fixedly installed side by side between the second support plate and the workbench.
[0010] Preferably, three strip-shaped grooves are provided side by side on both sides of the worktable, and the three upper roller shafts are all embedded and slidably installed in the strip-shaped grooves.
[0011] Preferably, the second support plate is slidably connected to the worktable via two rectangular sliders, and an arc plate is installed on one side of both the first and second support plates.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1) This device for packing and collecting valve bags uses adjusting bolts to move the two side guards along the pressure seat under the action of the slide, thereby changing the distance between the two side guards. In use, the distance between the two guards is changed according to the size of the valve bag, and several valve bags are placed between the two guards to align the valve bags with the guards and baffles. The hydraulic cylinder is then controlled to compress the valve bags, achieving the effect of valve bag alignment and compression, which is beneficial for further packing and collecting the valve bags.
[0014] 2) This valve bag packing and collecting device uses an electric telescopic rod to make the upper roller shaft contact the compressed valve bag, and further controls the drive motor to rotate the upper roller shaft. In conjunction with the lower roller shaft, several valve bags will be conveyed to the second support plate. Before use, by pressing the second support plate and putting the packaging bag on the outside of the first and second support plates, the valve bags can be put into the packaging bag after being conveyed out of the worktable, thus completing the packing and collecting of valve bags, making the packing and collecting of valve bags more convenient and simple.
