Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of carton processing, and particularly relates to a rapid flattening mechanism. Background Art
[0002] Flattening cartons can reduce their volume, thereby making more efficient use of storage and transportation space. During transportation and warehousing, more flattened cartons can be stacked, improving space utilization and reducing costs. However, current cartons are usually flattened simply by using a flattening plate. However, the flattening plate may not be able to apply uniform pressure to all parts of the carton, resulting in poor flattening effects in some areas, with wrinkles or unevenness still existing. In addition, the strength and stability of the carton during the flattening process are not good, and the cardboard of the carton cannot be tightly combined together, resulting in larger gaps between the cardboards. If there are large gaps between the cardboards, the stability of the carton will also be affected. When stacking or storing cartons, the gaps may cause the carton to tilt, slide or become unstable, increasing collapse or other safety risks. In order to solve this problem, it is now necessary to develop a rapid flattening mechanism. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figures 1 to 5 The utility model provides a technical solution: a fast flattening mechanism, comprising: a flattening work box 100 and a bottom box 400, the bottom of the flattening work box 100 is connected to the bottom box 400, a hydraulic cylinder 900 is installed on the upper left side of the flattening work box 100, and a flattening plate 700 is connected to the bottom of the hydraulic cylinder 900 through a lifting top plate 800;
[0027] The left side of the flattening working box 100 is concave downward to form a carton flattening groove 240. A linear guide groove 150 is respectively opened on the front and rear sides of the carton flattening groove 240. A push plate 230 is arranged on the left side of the carton flattening groove 240. The front and rear sides of the push plate 230 are respectively slidably connected with the two linear guide grooves 150 through sliders 160. A push rod 140 is installed in the middle of the left side of the push plate 230.
[0028] A lower rotating roller 110 is installed at the lower right side of the flattening work box 100, an upper rotating roller 130 is installed above the lower rotating roller 110, two motors are installed at the lower right side of the back of the flattening work box 100, a side fixing plate 170 is installed on the front and back sides of the lower right side of the flattening work box 100, and a plurality of sliding rollers 180 are installed between the two side fixing plates 170.
[0029] A carton entrance 300 is provided in the middle of the left side of the flattening work box 100, a carton exit 200 is provided in the middle of the right side, and a process observation window 600 is installed in the middle of the front side of the flattening work box 100. During the flattening process, the staff can observe the flattening process through the process observation window 600.
[0030] The process observation window 600 is made of a highly transparent tempered glass, and the position of the carton flattening groove 240 is symmetrical to the position of the gap between the upper rotating roller 130 and the lower rotating roller 110 .
[0031] A rotating shaft is installed in the middle of the front and rear sides of the upper rotating roller 130 and the lower rotating roller 110 respectively, and two motors are connected to the rotating shafts at the rear sides of the upper rotating roller 130 and the lower rotating roller 110 respectively, and the two motors rotate in opposite directions.
[0032] A bearing seat 120 is installed in front of the upper rotating roller 130 and the lower rotating roller 110 respectively. The two bearing seats 120 are respectively fixed to the inside of the flattening work box 100 and the process observation window 600, and a bearing is installed in the middle position. The front sides of the upper rotating roller 130 and the lower rotating roller 110 are connected to the inner side of the bearing through a rotating shaft.
[0033] Example 1: Please refer to Figures 1 to 5 In actual use, the carton to be flattened is placed into the carton flattening slot 240 through the carton entrance 300. Next, the hydraulic cylinder 900 is started, so that the hydraulic cylinder 900 drives the flattening plate 700 to descend through the lifting top plate 800 to press the carton into the carton flattening slot 240 for preliminary flattening, so that the gap between the cardboards is reduced. After flattening, the hydraulic cylinder 900 drives the flattening plate 700 to rise. The two motors can be started in advance, and the output shafts of the two motors can respectively drive the upper rotating roller 130 and the lower rotating roller 110 to rotate in opposite directions through the rear rotating shaft. When the upper rotating roller 130 and the lower rotating roller 110 rotate, the bearings on the inner sides of the two bearing seats 120 can be driven to rotate through the two front rotating shafts;
[0034] Next, the staff holds the pushing rod 140 and pushes the pushing plate 230 to the right. The pushing plate 230 can drive the two sliders 160 to move along the two linear guide grooves 150. At the same time, the pushing plate 230 can push the flattened carton in the carton flattening groove 240 to between the upper roller 130 and the lower roller 110 in the rotating process. The upper roller 130 and the lower roller 110 can further flatten the carton quickly while rotating, further promoting the cardboards to fit closely together, which helps to improve the structural strength and stability of the carton. The gaps between the closely fitted cardboards are reduced, which can reduce the occupied space and facilitate stacking.
[0035] The position of the carton flattening groove 240 is symmetrical to that of the flattening plate 700. A connecting shaft is installed on the front and rear sides of each sliding roller 180, and a plurality of connecting bearings are installed on the upper front sides of the two side fixing plates 170. The front and rear sides of each sliding roller 180 are connected to the inner sides of the connecting bearings on the front and rear sides through the connecting shafts.
[0036] The side fixing plate 170 is higher on the left and lower on the right, and the installation heights of the plurality of sliding rollers 180 are equidistantly decreased from left to right, and a conveyor 190 is disposed below the plurality of sliding rollers 180 .
[0037] A temporary storage chamber 210 is opened on the left side inside the bottom box 400, and two box doors are hingedly installed on the left side of the front of the bottom box 400. A central partition 220 is installed in the middle of the temporary storage chamber 210. Cartons damaged during the flattening process or cartons that need other reprocessing can be temporarily stored above and below the central partition 220 in the temporary storage chamber 210 by opening the box door. Damaged cartons or cartons that need to be reprocessed are temporarily stored above and below the central partition 220, which can facilitate staff to quickly find and process these cartons without having to search for or move these cartons in the entire working area, thereby improving work efficiency.
[0038] Example 2: Please refer to Figure 1 and Figure 2 According to the further elaboration of the first embodiment, when the upper roller 130 and the lower roller 110 rotate in opposite directions, a conveying force to the right can be generated. When the carton enters between the upper roller 130 and the lower roller 110, the rotation in the opposite direction can push the carton to move to the right to the carton outlet 200. This process does not require manual intervention, which improves production efficiency and automation. Then the flattened carton can pass through the carton outlet 200 and fall to the multiple sliding rollers 180. Then the carton can slide to the lower right through the multiple sliding rollers 180 and fall above the conveyor 190. Then the flattened carton can be transported to the stacking point through the conveyor 190 for stacking. While the carton slides, it can drive the multiple sliding rollers 180 to rotate. At the same time, the multiple sliding rollers 180 drive the inner sides of the multiple connecting bearings to rotate respectively through the connecting shafts. The rotation of the sliding rollers 180 can reduce the friction between the carton and the sliding rollers 180, which can reduce the wear and resistance of the carton during transportation, make the carton easier to slide, and reduce the jamming phenomenon during transportation.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
