Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1 and 4. This utility model provides a technical solution: a color printing packaging sealing mechanism, including a base 1, a motor 2 is provided on one side of the front end of the base 1, a conveyor belt 3 is provided on the output shaft of the motor 2, a mounting frame 4 is fixedly connected to the middle of the upper end of the base 1, sliding grooves 5 are opened on both sides of the inner wall of the mounting frame 4, a lifting mechanism 6 is bolted to the upper end of the mounting frame 4, a limit mechanism 7 is fixedly connected to the lower end of the lifting mechanism 6, a controller 8 is fixedly connected to the front end of the mounting frame 4, a guide plate 9 is fixedly connected to one side of the base 1, the lifting mechanism 6 includes a cylinder 61, the lower end of the cylinder 61 is connected to the mounting frame 4... The upper end of the frame 4 is bolted to the cylinder 61, which is equipped with a lifting plate 62. A scale line 63 is provided on one side of the lifting plate 62. Slider 64 is fixedly connected to both the front and rear ends of the lifting plate 62. A spring 65 is fixedly connected to the lower end of the lifting plate 62. A fixing frame 66 is fixedly connected to the lower end of the spring 65. A pressing roller 67 is rotatably connected to the inner wall of the fixing frame 66. A cutting blade 68 is fixedly connected to the lower end of the lifting plate 62. A sealing belt 69 is rotatably connected to one side of the lifting plate 62. One end of the motor 2 is detachably connected to one end of the base 1. The output shaft of the motor 2 is connected to one side of the conveyor belt 3.

[0025] One side of the conveyor belt 3 is connected to the output shaft of motor 2 via a transmission device to ensure that the conveyor belt 3 can smoothly transport the carton. The slide 5 in the mounting frame 4 cooperates with the slider 64 to allow the lifting plate 62 to move smoothly in the vertical direction. The controller 8 is used to receive external signals and control the actions of cylinder 61, motor 2 and motor 71 to realize the automatic lifting of the lifting plate 62. The guide plate 9 guides the carton away from the conveyor belt 3 and ensures that the carton can be used later. The pressing roller 67 and the cutting knife 68 work together to press and cut the sealing strip 69 during the sealing process to achieve a seal at the carton opening. During the operation, the carton is first placed on the conveyor belt 3. As the conveyor belt 3 moves, the carton is sent to the bottom of the mounting frame 4. After receiving the signal, the controller 8 commands the cylinder 61 to act, and the lifting plate 62 moves up and down accordingly to achieve precise sealing of the carton. The sealing tape 69 is cut by the cutting blade 68, completing the sealing process. The sealing process is highly automated, easy to operate, and the sealing quality is stable and reliable. In order to ensure the accuracy and stability of the sealing process, the front and rear ends of the lifting plate 62 are equipped with sliders 64. Multiple sliders 64 are precision machined to ensure a tight fit with the inner wall of the slide groove 5, thereby realizing the smooth sliding of the lifting plate 62.

[0026] Please refer to Figure 2. In order to quickly seal the cartons of different sizes in the mounting frame 4, the telescopic end of the cylinder 61 is fixedly connected to the upper end of the lifting plate 62, one side of the lifting plate 62 is fixedly connected to one side of the scale line 63, and the outer wall of the slider 64 is adapted to and slidably connected to the inner wall of the slide groove 5.

[0027] Meanwhile, the spring 65 at the lower end of the lifting plate 62 is designed to provide a certain pressure to ensure that the lifting plate 62 maintains stable contact with the mounting frame 4 during the lifting process, reducing vibration and noise. In addition, a pressing roller 67 is rotatably connected to the inner wall of the fixed frame 66 fixed to the lower end of the lifting plate 62. The pressing roller 67 is used to apply pressure to the sealing strip 69 during the sealing process to ensure that the sealing strip 69 fits tightly against the surface of the carton, thereby improving the sealing quality. The cutting blade 68 is set on one side of the lifting plate 62 to cut off the excess sealing strip 69 after sealing, ensuring a neat and beautiful seal. The output shaft of motor 2 is connected to one side of conveyor belt 3 to ensure that conveyor belt 3 can transport cartons from one end of base 1 to the other. At the same time, it works in conjunction with lifting mechanism 6 to realize automatic sealing of cartons of different heights. Controller 8 is used to control the operation of the whole device, including the lifting action of lifting mechanism 6, the extension and retraction action of cylinder 61 and cutting action of cutting blade 68, to ensure the automation and intelligence of the sealing process. It can quickly and accurately seal cartons of different sizes, improve production efficiency, reduce labor costs, and ensure sealing quality.

[0028] Please refer to Figure 3. In order to quickly fix the carton in the mounting frame 4, the limiting mechanism 7 includes a second motor 71. The lower end of the second motor 71 is detachably connected to the upper end of the lifting plate 62. The output shaft of the second motor 71 is provided with a drive wheel 72. The outer wall of the drive wheel 72 is provided with a belt 73. The lower end of the belt 73 is connected to a driven wheel 74. The inner wall of the driven wheel 74 is inserted with a double screw 75. The outer wall of the double screw 75 is threaded with a movable block 76. The lower end of the movable block 76 is welded with a limiting plate 77. A ball bearing 78 is embedded in one side of the limiting plate 77. The output shaft of the second motor 71 is connected to one side of the drive wheel 72. The outer wall of the drive wheel 72 is sleeved with the inner wall of the belt 73. The threaded sections at both ends of the double screw 75 are arranged oppositely or in reverse.

[0029] When the carton moves on the workbench, motor 71 is started according to the size of the carton. The output of motor 71, through the combined action of drive wheel 72, belt 73, and driven wheel 74, drives the bidirectional screw 75 to rotate. The bidirectional screw 75 can move the two limit plates 77 closer or further away. The ball bearings 78 can limit the sides of the carton. At the same time, the cylinder 61 can control the lifting plate 62 to descend, working with the sealing tape 69 and the cutting knife 68 to perform packaging sealing. When the carton moves, the ball bearings 78... The sealing tape 69 also rolls, thus limiting the movement of the carton without affecting its movement. The operation is simple and convenient. After the sealing tape 69 is cut, the other side of the carton comes into contact with the pressing roller 67. The pressing roller 67 is lower than the sealing tape 69 and is lifted by the carton. Under the action of the spring 65, it rises together with the fixing frame 66. Then the pressing roller 67 rolls to flatten the applied tape. After the carton is removed, the pressing roller 67 returns to its original position. In addition, in order to improve the efficiency and quality of sealing, the sealing tape 69 is made of a heatable material and its surface is coated with hot melt adhesive. When the carton is fixed in the mounting frame 4, the sealing tape 69 is moved to the sealing position of the carton by the lifting plate 62. Then, the sealing tape 69 is heated to melt the hot melt adhesive and adhere it to the sealing position of the carton to achieve sealing. After sealing is completed, the lifting mechanism 6 removes the sealing tape 69, and the carton can continue to move from the mounting frame 4.

[0030] Working principle: First, the conveyor belt 3 is connected to the output shaft of motor 2 via a transmission device to ensure that the conveyor belt 3 can smoothly transport the carton. The slide 5 in the mounting frame 4 cooperates with the slider 64 to allow the lifting plate 62 to move smoothly in the vertical direction. The controller 8 is used to receive external signals and control the actions of cylinder 61, motor 2 and motor 71 to realize the automatic lifting of the lifting plate 62. The guide plate 9 guides the carton away from the conveyor belt 3 and ensures that the carton can be used later. The pressing roller 67 and the cutting knife 68 work together to press and cut the sealing strip 69 during the sealing process to achieve a seal at the carton opening. During the operation, the carton is first placed on the conveyor belt 3. As the conveyor belt 3 moves, the carton is sent to the bottom of the mounting frame 4. After receiving the signal, the controller 8 commands the cylinder 61 to act, and the lifting plate 62 moves up and down accordingly to achieve precise sealing of the carton. The sealing tape 69 is cut by the cutting blade 68, completing the sealing process. The sealing process is highly automated, easy to operate, and the sealing quality is stable and reliable. To ensure the accuracy and stability of the sealing process, sliders 64 are provided at both the front and rear ends of the lifting plate 62. Multiple sets of sliders 64 are precision-machined to ensure a tight fit with the inner wall of the slide groove 5, thereby achieving smooth sliding of the lifting plate 62. At the same time, the spring 65 at the lower end of the lifting plate 62 is provided to provide a certain pressure to ensure that the lifting plate 62 maintains stable contact with the mounting frame 4 during the lifting process, reducing vibration and noise. In addition, the inner wall of the fixed frame 66 fixed to the lower end of the lifting plate 62 is rotatably connected to a pressing roller 67. The pressing roller 67 is used to apply pressure to the sealing tape 69 during the sealing process to ensure that the sealing tape 69 fits snugly against the inner wall of the mounting frame 5. The carton surface is tightly fitted, thereby improving the sealing quality. The cutting blade 68 is set on one side of the lifting plate 62 to cut off the excess sealing tape 69 after sealing, ensuring a neat and beautiful seal. The output shaft of motor 2 is connected to one side of the conveyor belt 3 to ensure that the conveyor belt 3 can transport the carton from one end of the base 1 to the other end. At the same time, it works in conjunction with the lifting mechanism 6 to realize automatic sealing of cartons of different heights. The controller 8 is used to control the overall operation of the device, including the lifting action of the lifting mechanism 6, the extension and retraction action of the cylinder 61, and the cutting action of the cutting blade 68, ensuring the automation and intelligence of the sealing process. It can quickly and accurately seal cartons of different sizes, improve production efficiency, reduce labor costs, and ensure sealing quality.

[0031] Then, as the carton moves on the worktable, motor 71 is started according to the size of the carton. The output of motor 71, through the combined action of drive wheel 72, belt 73, and driven wheel 74, drives the bidirectional screw 75 to rotate. The bidirectional screw 75 can move the two limit plates 77 closer or further away. The ball bearings 78 can limit the two sides of the carton. At the same time, the cylinder 61 can control the lifting plate 62 to descend, working with the sealing tape 69 and the cutting knife 68 to perform packaging sealing. When the carton moves, the ball bearings 78 also roll, thus limiting the carton without affecting its movement. The operation is simple and convenient. After the sealing tape 69 is cut, the other side of the carton abuts against the pressing roller 67. The pressing roller 67 is lower than the sealing tape 69 and is lifted by the carton. Under the action of spring 65, it rises together with the fixing frame 66. Then, the pressure roller 67 rolls to flatten the applied tape. After the carton is removed, the pressure roller 67 returns to its original position. In addition, in order to improve the efficiency and quality of sealing, the sealing tape 69 is made of a heatable material and its surface is coated with hot melt adhesive. After the carton is fixed in the mounting frame 4, the sealing tape 69 is moved to the sealing position of the carton by the lifting plate 62. Then, the sealing tape 69 is heated so that the hot melt adhesive melts and adheres to the sealing position of the carton, thus achieving sealing. After sealing is completed, the lifting mechanism 6 removes the sealing tape 69, and the carton can continue to move from the mounting frame 4. The above is the working process of the entire device.
