Detailed Implementation

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] Reference Figures 1-5 As shown, a carton sealing machine includes: a support frame 100 and a conveyor roller 101 fixedly mounted on the support frame 100 for conveying cartons. The conveyor roller 101 is fixedly provided with a positioning mechanism 200 for limiting the position of the cartons and a pressing mechanism 300 for pressing the top of the folded cartons. The pressing mechanism 300 includes left and right pressing components fixedly mounted on the conveyor roller 101 and front and rear pressing components 400 mounted on the pressing components. The left and right pressing components include a movable plate 303 and a pressure rod 304 fixedly mounted on the bottom surface of the movable plate 303.

[0031] During use, the carton is placed on the conveyor roller 101 of the carton sealing machine. The conveyor roller 101 starts to rotate, conveying the carton forward along a predetermined path. During the conveying process, the positioning mechanism 200 limits the carton to ensure that it does not shift or tilt during the conveying process and maintains the correct position. When the carton is conveyed to the pressing mechanism 300, the left and right pressing components start to work. The movable plate 303 moves downward, driving the pressure rod 304 on its bottom surface to press the left and right sides of the carton, ensuring that the top of the folded carton is flat and tightly sealed. When the left and right pressing components complete the pressing, the front and rear pressing components 4... The mechanism 300 starts working, causing the movable plate 303 and the pressure bar 304 to work together to press the front and back sides of the carton, further enhancing the sealing effect of the top of the carton. After pressing from the left and right and front and back, the top of the carton is firmly sealed. The automated pressing mechanism 300 can quickly complete the sealing of the top of the carton, greatly improving the sealing efficiency. The coordinated work of the left and right pressing components and the front and back pressing components 400 can ensure that the top of the carton is pressed evenly in all directions, thereby ensuring the quality of the sealing.

[0032] Reference Figures 2-4 As shown, the left and right pressing components also include: a first bracket 301 and an electric telescopic rod 302; the first bracket 301 is fixedly provided on the conveying roller 101 behind the positioning mechanism 200, the top of the first bracket 301 is fixedly provided with an electric telescopic rod 302, the output end of the electric telescopic rod 302 is vertically downward and fixedly provided with a movable plate 303, and the bottom surface of the movable plate 303 is fixedly provided with multiple sets of pressure rods 304 at fixed intervals.

[0033] When the carton is conveyed below the movable plate 303, the electric telescopic rod 302 on the first bracket 301 located behind the positioning mechanism 200 on the conveyor roller 101 starts. The output end of the electric telescopic rod 302 extends vertically downward, driving the movable plate 303, which is fixed at its output end, to move downward together. Multiple sets of pressure rods 304 are fixedly spaced on the bottom surface of the movable plate 303. As the movable plate 303 moves downward, these pressure rods 304 gradually approach the left and right sides of the carton. When the pressure rods 304 contact the left and right sides of the carton, they apply uniform pressure to the top of the carton, ensuring that the top of the folded carton is flat and tightly sealed. At this time, the electric telescopic rod 302 continues to maintain a certain downward pressure to maintain the sealing effect.

[0034] Reference Figures 4-5As shown, the front and rear pressing assembly 400 includes: a rotating plate 402, a pressure plate 403, and a driving component; wherein, a fixed frame 401 is fixedly provided on the upper end of the movable plate 303, the rotating plate 402 is hinged on the fixed frame 401, the edge of the rotating plate 402 is hinged to the pressure plate 403 for pressing the carton, and a driving component is also fixedly provided on the movable plate 303 for driving the rotating plate 402 to rotate so that the pressure plate 403 presses the top of the carton.

[0035] In the above scheme, when the output end of the electric telescopic rod 302 extends vertically downward, driving the movable plate 303 fixed at its output end to move downward together, the driving component fixed on the movable plate 303 is activated. With the driving component, the rotating plate 402 begins to rotate. Since the edge of the rotating plate 402 is hinged with a pressure plate 403, when the rotating plate 402 rotates, the pressure plate 403 will also move accordingly, gradually approaching the top of the carton. When the pressure plate 403 contacts the top of the carton, it will press the front and rear sides of the carton to ensure that the top of the folded carton is flat and tightly sealed in the front and rear directions. The front and rear pressing assembly 400, through the design of the hinge and the driving component, realizes the pressing and sealing of the top of the carton in the front and rear directions, which is compact and efficient.

[0036] Reference Figure 5 As shown, the driving component includes a hydraulic rod 404 and a slider 405; the top end of the movable plate 303 is fixedly provided with a hydraulic rod 404, the output end of the hydraulic rod 404 is horizontally arranged and fixedly provided with a slider 405, and the back of the rotating plate 402 is provided with a groove 406 for the slider 405 to slide.

[0037] When the carton is conveyed below the movable plate 303, the hydraulic rod 404 on the movable plate 303 is activated, and its output end extends. This extension causes the slider 405 to move horizontally, interacting with the rotating plate 402. The slider 405 is designed to match the groove 406 on the back of the rotating plate 402. As the slider 405 moves, it slides along the path of the groove 406, thereby pushing the rotating plate 402 to rotate around its hinge point. As the rotating plate 402 rotates, the pressure plate 403 hinged to its edge gradually approaches the top of the carton. When the pressure plate 403 contacts the carton, it begins to press evenly on the front and back sides of the carton, ensuring that the top of the carton is flat and tightly fitted in the front-back direction.

[0038] Reference Figures 2-3As shown, the positioning mechanism 200 includes: a limiting plate 207, a rotating roller 208, and an adjusting member; wherein, a second bracket 201 is fixedly provided on the conveying roller 101, and two sets of mounting frames 206 that can move closer or further apart are slidably provided on the second bracket 201 through the adjusting member, and a limiting plate 207 corresponding to each mounting frame 206 is fixedly provided on the bottom surface of the mounting frame 206, and multiple sets of rotating rollers 208 are rotatably provided at intervals within the limiting plate 207, and the rotating rollers 208 are in contact with the surface of the carton.

[0039] In the above scheme, based on the width of the carton, the operator adjusts the distance between the two sets of mounting frames 206 using the adjusting mechanism. The conveying roller 101 starts to operate, conveying the carton forward. When the carton enters the positioning mechanism 200 area, both sides of the carton are contacted by the limiting plate 207 and its rotating roller 208. The rotating roller 208 rotates as the carton moves, reducing friction between the carton and the limiting plate 207, while ensuring the stability of the carton during conveying. As the carton continues to be conveyed, the limiting plate 207 and its rotating roller 208 limit the sides of the carton, preventing the carton from shifting or tilting during conveying. The rolling action of the rotating roller 208 also allows the carton to pass through the positioning mechanism 200 more smoothly. By adjusting the distance between the mounting frames 206, the positioning mechanism 200 can adapt to cartons of different widths, improving the versatility and flexibility of the equipment.

[0040] Reference Figure 3 As shown, the adjusting component includes: a drive motor 203, a bidirectional screw 204, and a threaded block 205; wherein, the bidirectional screw 204 is rotatably mounted inside the second bracket 201, the bidirectional screw 204 has two sections of threads with opposite directions and threaded blocks 205 are threadedly fitted on the threads at both ends, the second bracket 201 has a limiting groove 202 for sliding the threaded blocks 205, the drive motor 203 is fixedly mounted on the second bracket 201, the output shaft of the drive motor 203 is horizontally set and its top end is fixedly connected to the bidirectional screw 204 through a coupling.

[0041] In use, the bidirectional screw 204 begins to rotate as the drive motor 203 starts, based on the width of the carton to be packaged. Since the bidirectional screw 204 has two sections of threads with opposite directions, when the screw rotates, the threaded blocks 205 on the two sections of threads move in opposite directions. The threaded blocks 205 are designed to slide within the limiting grooves 202 opened on the second bracket 201. Therefore, when the threaded blocks 205 move, they respectively drive the mounting brackets 206 fixedly connected to them to move, thereby changing the distance between the two sets of mounting brackets 206. The operator continues to adjust the operation of the drive motor 203 by observation or measurement until the distance between the two sets of mounting brackets 206 matches the width of the carton. At this point, the limiting plate 207 and its rotating roller 208 will be able to accurately limit the carton.

[0042] Reference Figure 2 As shown, the packaging machine also includes a packaging component 500 fixedly disposed on the conveying roller 101 and located behind the pressing mechanism 300 for packaging the pressed carton.

[0043] In the above scheme, the sealing component 500 may include a tape-applying mechanism, a hot melt adhesive spraying mechanism, or other forms of sealing mechanism, all of which are existing technologies. When the carton is conveyed to the sealing component 500, the sealing component 500 begins to seal the carton. For example, if the sealing component 500 is a tape-applying mechanism, it will apply tape to the opening of the carton to close it. If the sealing component 500 is a hot melt adhesive spraying mechanism, it will spray hot melt adhesive onto the opening of the carton and seal it by cooling and curing. After the carton is completely sealed, the conveying roller 101 continues to operate, conveying the sealed carton to the next process or collection area. At this point, the entire carton sealing process is complete.

[0044] In summary, the carton sealing machine provided by this utility model, during use, places the carton on the conveyor roller 101 of the carton sealing machine. The conveyor roller 101 starts to operate, conveying the carton forward along a predetermined path. When the carton enters the positioning mechanism 200 area, the two sides of the carton are contacted by the limiting plate 207 and the rotating roller 208 on it, limiting the two sides of the carton and preventing the carton from shifting or tilting during the conveying process. When the carton is conveyed to the pressing mechanism 300, the left and right pressing components start to work. The movable plate 303 moves downward, driving the pressure rod 304 on its bottom surface to press the left and right sides of the carton. The hydraulic rod 404 on the movable plate 303 is activated. As the hydraulic rod 404 is activated, when the slider 405 moves, it slides along the path of the slide groove 406, thereby pushing the rotating plate 402 to rotate around its hinge point. As the rotating plate 402 rotates, the pressure plate 403 hinged to its edge gradually approaches the top of the carton. When the pressure plate 403 comes into contact with the carton, it begins to press evenly on the front and back sides of the carton. When the carton is conveyed to the bottom of the sealing component 500, the sealing component 500 begins to seal the carton.
