Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0030] Reference Figure 1 and Figure 2The utility model provides an embodiment: a color printing packaging laminating device, including a frame 1, a driven roller 2 is rotatably connected to one side of the frame 1, a motor 3 is fixedly connected to the other side of the frame 1, an active roller 4 is fixedly connected to the output end of the motor 3, a tensioning roller 5 is arranged on the top of the frame 1, a frame 6 is fixedly connected to the top of the frame 1, a motor 2 7 is fixedly connected to one side of the frame 6, a rotating shaft 8 is fixedly connected to the output end of the motor 27, a bevel gear 19 is fixedly connected to the outer wall of the rotating shaft 8, a symmetrically arranged bidirectional threaded rod 10 is rotatably connected inside the frame 6, and a bevel gear 2 11 is fixedly connected to one end of the bidirectional threaded rod 10, The bevel gear 2 11 is meshed with the outer wall of the bevel gear 1 9, the outer wall of the bidirectional threaded rod 10 is threadedly connected with a slider 12, the slider 12 is internally slidably connected with a limit column 13, one end of the limit column 13 is fixedly connected with a connecting block 14, one side of the connecting block 14 is rotatably connected with a hot pressing roller 15, and the outer wall of the limit column 13 is provided with a reset component, the reset component is used to reset the connecting block 14 to the position of the original slider 12, and the reset component includes a first spring 16, the first spring 16 is internally sleeved on the outer wall of the limit column 13, one end of the first spring 16 is fixedly connected to the bottom of the connecting block 14, and the other end of the first spring 16 is fixedly connected to the top of the slider 12;

[0031] Specifically, first, the printing and packaging roller to be laminated needs to be installed on the driven roller 2. The printing and packaging roller is fixed to the equipment through the driven roller 2 to provide stable support for subsequent lamination operations. After the installation is completed, one end enters between the hot pressing rollers 15 through the tensioning roller 5. The function of the tensioning roller 5 is to provide appropriate tension so that the printing and packaging roller can pass through the hot pressing roller 15 smoothly and tightly to ensure the uniformity and effect of the lamination process. The position and pressure between the hot pressing rollers 15 directly affect the effect of the printing and packaging lamination. After lamination by the hot pressing roller 15, the printing and packaging roller continues to move forward, passes through the bottom of the limiting wheel 21, and is finally wrapped around the outer wall of the active roller 4 for collection. The active roller 4 is responsible for orderly winding the laminated printing and packaging rollers to ensure that the laminated materials can be neatly collected and stored for subsequent processing and use. When it is necessary to adjust the spacing between the hot pressing rollers 15 The operation is simple and effective. Start the motor 2 7. The output end of the motor 2 7 drives the rotating shaft 8 to start rotating. The rotating shaft 8 drives the bevel gear 2 11 to rotate through the bevel gear 1 9. The bevel gear 2 11 further drives the bidirectional threaded rod 10 to rotate. The rotation of the bidirectional threaded rod 10 enables the slider 12 to move in a specific direction inside the frame 1 6. The movement of the slider 12 is guided by the outer wall of the limit column 13 to ensure that the slider 12 slides smoothly along the predetermined track. During the movement, the slider 12 squeezes the limit column 13. This squeezing force directly acts on the hot pressing rollers 15 to change the spacing and pressure between the hot pressing rollers 15. By adjusting the squeezing force of the slider 12 on the limit column 13, the pressure between the hot pressing rollers 15 can be accurately controlled. At this time, the first spring 16 provides different reaction forces under different deformation degrees to further control the pressure between the hot pressing rollers 15.

[0032] Reference Figure 3 The top of the frame 1 is fixedly connected with a support column 28, the top of the support column 28 is fixedly connected with a frame 26, the inside of the frame 26 is fixedly connected with a motor 3 17, the output end of the motor 3 17 is fixedly connected with a wheel disc 18, the inside of the wheel disc 18 is rotatably connected with a connecting rod 19, one end of the connecting rod 19 is rotatably connected with a cross bar 27, the bottom of the cross bar 27 is fixedly connected with a connecting column 22, the outer wall of the connecting column 22 is slidably connected to the inside of the frame 26, the bottom of the frame 26 is fixedly connected with a blade 23, the outer wall of the connecting column 22 is fixedly connected to a limiting plate 24, the outer wall of the connecting column 22 is sleeved with a second spring 25, one end of the second spring 25 is fixedly connected to the bottom of the limiting plate 24, and the other end of the second spring 25 is fixedly connected to the inside of the frame 26, a bracket 20 is fixedly connected to one side of the support column 28, and the bracket 20 is rotatably connected to a limiting wheel 21;

[0033] Specifically, when it is necessary to cut the package, the motor 3 17 is started, and its output end drives the wheel disc 18 to start rotating. The rotational movement of the wheel disc 18 is transmitted to the cross bar 27 through the connecting rod 19, so that the cross bar 27 applies pressure downward. During the downward pressing process, the cross bar 27 is accurately limited by the connecting column 22 to ensure that it only moves up and down in a straight line. This limiting mechanism ensures that the movement trajectory of the cross bar 27 is vertical, thereby avoiding lateral deviation and improving the cutting accuracy. The connecting column 22 drives the blade 23 to move downward to cut the packaging paper. During the downward pressing process, the blade 23 The sharp blade can easily penetrate the packaging paper to achieve precise cutting. After the cutting is completed, the motor 17 continues to rotate until the wheel 18 completes a circle of rotation and resets the entire system. At the same time, the second spring 25 supports the limit plate 24 to move upward through tension, driving the connecting column 22 to lift, so that the blade 23 returns to the initial position. This design not only ensures that the blade 23 can be quickly reset, but also provides additional supporting force through the action of the second spring 25 to prevent the blade 23 from accidentally falling due to gravity when the power is not on, thereby protecting the safety of the operator.

[0034] Working principle: When the color printing and packaging laminating device is used, the printing and packaging roller to be pressed is first installed on the driven roller 2, and then one end passes through the tensioning roller 5 and enters between the hot pressing rollers 15, and then passes through the bottom of the limiting wheel 21 and is wrapped around the outer wall of the active roller 4 for collection. When the spacing between the hot pressing rollers 15 needs to be adjusted, the output end of the motor 27 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the bevel gear 2 11 to rotate through the bevel gear 1 9, and the bevel gear 2 11 drives the bidirectional threaded rod 10 to rotate. When the bidirectional threaded rod 10 rotates, it drives the slider 12 to move relatively inside the frame 1 6, so that the slider 12 slides on the outer wall of the limiting column 13, and at the same time, the limiting column 13 is squeezed by the slider 12, thereby generating pressure on the hot pressing roller 15, through The pressure between the hot pressing rollers 15 is controlled by controlling the different deformation degrees of the extruded first spring 16, thereby controlling the pressure on the printed packaging film. Subsequently, when the package needs to be cut, the output end of the motor three 17 drives the wheel disc 18 to rotate. When the wheel disc 18 rotates, the connecting rod 19 drives the cross bar 27 to be pressed down. The cross bar 27 is limited by the connecting column 22 to make up and down linear motion, and then the connecting column 22 drives the blade 23 to be pressed down to cut the packaging paper. Subsequently, the output end of the motor three 17 rotates one circle to reset, and the limit plate 24 is pushed by the tension support of the second spring 25, thereby driving the connecting column 22 to lift and reset the blade 23. It can also prevent the blade 23 from being limited when the motor three 17 is not powered on, thereby preventing the blade 23 from falling.
