Description

Technical Field

[0001] The invention belongs to the technical field of laminating machines, and in particular relates to a full-automatic laminating machine and a working method for controlling the gap between rollers by rotation. Background Art

[0002] The fully automatic laminating machine is a highly efficient and continuously operating mechanical equipment, which is mainly used to evenly coat a layer of molten plastic film (such as polyethylene, polypropylene, etc.) on the surface of various substrates (such as paper, plastic film, cloth, etc.) to enhance the waterproof, moisture-proof, oil-proof, airtight and mechanical strength properties of the substrate. The equipment is usually composed of core parts such as unwinding device, laminating device, winding device and control system. Among them, the laminating roller in the laminating device is the key component, which is responsible for evenly coating the molten plastic on the surface of the substrate. By accurately controlling the rotation speed, temperature and contact pressure between the laminating roller and the substrate, the initial regulation of the coating thickness and uniformity can be achieved.

[0003] At present, the existing laminating machines still have the following problems during use: the gap between the laminating rollers is often difficult to flexibly adjust according to different usage requirements. This limitation makes it difficult to accurately control the coating thickness in the actual production process, which in turn affects the coating uniformity and product quality. In addition, since it is impossible to dynamically adjust the laminating roller gap according to the substrate type, coating material characteristics and final product performance requirements, it is easy to cause unnecessary material loss and increase in production costs. What is more serious is that the lack of coating thickness and uniformity may also cause quality problems in subsequent processing. At the same time, it is difficult for existing laminating machines to provide targeted wind drying according to the coating thickness, thereby limiting the application and development of fully automatic laminating machines in a wider range of fields; therefore, there are deficiencies and cannot meet the production and use needs of manufacturers. Therefore, it is necessary to further improve.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fully automatic laminating machine and a working method for rotating and controlling the gap between rollers are provided, in order to achieve a more practical purpose. Summary of the invention

[0039] See also Figures 7 to 9 The guide assembly 33 includes a guide frame 331 with an open groove. The left and right sides of the guide frame 331 are fixedly connected to the lower coating seat 31 through a mounting frame 332. One side of the guide frame 331 is rotatably connected to the adjusting roller 321 through a rotating shaft 333; a guide slide bar 334 is fixedly installed in the open groove of the guide frame 331, and a guide slider 335 is slidably installed on the guide slide bar 334.

Adjust the current in the drying fan 241. When the coating is thicker, increase the current to improve the drying effect. When the coating is thinner, reduce the current to avoid energy waste. Since the coating on the substrate surface is thin, if the drying fan 241 is continuously driven to output a large current, it will not only cause energy waste, but may also cause unnecessary damage to the coating on the substrate surface. Therefore, this setting can reduce the current output of the drying fan 241, so that it can achieve effective control of electric energy while ensuring the drying effect of the coating on the substrate surface.

[0041] The working method of the fully automatic laminating machine for controlling the gap between rollers by rotation comprises the following steps: S1: The substrate is smoothly unwound through the unwinding device 11 and guided through the lower laminating seat 31 in the laminating machine body 10; S2: The coating liquid in the spray box 221 is uniformly sprayed on the surface of the substrate through the spray head 222, and a uniform and dense coating layer is initially formed on the substrate; S3: The coating roller 322 can be used to support and guide the substrate, and the coating on the surface of the substrate can be further uniformly treated by its rotation; S4: The drying fan 241 drives the drying airflow to pass through the vents on the flexible ventilation coil 244, and blows the drying airflow to the surface of the substrate to achieve efficient drying of the coating; S5: Finally, the treated substrate is rolled up by the rolling device 12 to complete the entire coating process.

[0042] The specific usage and function of this embodiment are as follows: Working principle: When in use, the substrate is smoothly unwound through the unwinding device 11 and guided to pass through the lower laminating seat 31 in the laminating machine body 10. While the substrate passes through this process, the program controls the start of the spray assembly 22, and the laminating liquid in the spray box 221 is evenly sprayed on the surface of the substrate through the spray head 222, thereby initially forming a uniform and dense coating on the substrate. Subsequently, the coated substrate continues to move forward and passes through the laminating channel formed by the laminating roller 322. The laminating roller 322 can be used to support and guide the substrate, and can also rotate the substrate. The coating on the surface is further treated evenly to ensure that the coating liquid is evenly coated on the substrate, effectively avoiding the problem of uneven distribution of the coating liquid; after being evenly treated by the coating roller 322, the drying fan 241 is started through program control, and the drying fan 241 is used to drive the dry airflow to pass through the vents on the flexible ventilation roll plate 244, and blow the dry airflow to the surface of the substrate to achieve efficient drying of the coating, so that the coating can be quickly cured and firmly attached to the substrate. Finally, the treated substrate is rolled up by the winding device 12 to complete the entire coating process; When the coating thickness on the substrate surface needs to be adjusted, the spacing between the coating rollers 322 needs to be adjusted. The internal program controls the power on and off of the electromagnet block 342 to achieve precise adjustment of the spacing between the coating rollers 322. When the electromagnet block 342 is powered off, the fixed iron ring 324 and the adjustment gear ring 323 are unlocked. At the same time, the electric retractor 232 is driven to start running through the control of the program. The telescopic rod of the electric retractor 232 is used to push the fixing part 233 and the adjustment plate 231 to move, and the adjustment plate 231 is used to adjust the spacing between the coating rollers 322. The movement drives the adjusting tooth plate 234 to mesh with the adjusting tooth ring 323, thereby driving the adjusting roller 321 to rotate, and driving the mounting shaft 3221 to drive the coating roller 322 to move in the adjusting groove 3211 on the adjusting roller 321, so that the distance between the two coating rollers 322 can be adjusted. After the distance between the coating rollers 322 is adjusted, the electromagnetic block 342 is energized, and the magnetic force of the electromagnetic block 342 can be used to magnetically lock the fixed iron ring 324, so as to ensure the stability of the gap between the coating rollers 322. In addition, when the installation shaft 3221 moves in the adjustment groove 3211 on the adjustment roller 321, the installation shaft 3221 simultaneously drives the guide slider 335 to slide on the guide slide bar 334, and at the same time squeezes the support spring 336. This arrangement can effectively enhance the stability of the coating roller 322 when it moves, and at the same time ensure the uniform coating effect of the coating roller 322 on the surface of the substrate. When the guide slider 335 slides on the guide slide bar 334, the adjustment slider simultaneously drives the induction slider 352 to slide on the sliding rheostat 351 using the movable rod 353, and the sliding rheostat 351 and the drying The fan 241 is electrically connected, and the sliding distance of the inductive slider 352 is inversely proportional to the change in resistance value. When the inductive slider 352 slides on the sliding rheostat 351, as the sliding distance increases, the resistance value of the entire sliding rheostat 351 also decreases. When the power supply voltage remains constant, according to Ohm's law, the current in the circuit is inversely proportional to the resistance, so the reduction in resistance will lead to an increase in current. Therefore, by adjusting the sliding distance of the inductive slider 352, the resistance value of the sliding rheostat 351 can be accurately controlled, thereby realizing the adjustment of the current size in the drying fan 241; When a thicker coating is required on the surface of the substrate, the two coating rollers 322 are driven away from each other by adjusting the roller 321 to rotate counterclockwise, so that the distance between the two coating rollers 322 is increased, and at the same time, the installation shaft 3221 drives the guide slider 335 to slide farther on the guide slider 334, and the sliding stroke of the induction slider 352 on the sliding rheostat 351 is increased, and the resistance is reduced, resulting in an increase in current, thereby increasing the drying air volume of the drying fan 241. This setting can make the electric energy output reasonable, ensure that the drying airflow can be evenly and quickly transmitted to the surface of the substrate, and thus improve the drying efficiency of the substrate surface coating; conversely, when a thinner coating is required on the surface of the substrate, the roller 321 is adjusted to rotate clockwise and drive the two coating rollers 32 2 are brought closer to each other, driving the distance between the two coating rollers 322 to decrease, and at the same time, the installation shaft 3221 drives the guide slider 335 to slide on the guide slider 334 to be closer, and the sliding stroke of the induction slider 352 on the sliding rheostat 351 is reduced, the resistance is increased, resulting in a decrease in current, thereby achieving effective control of energy and avoiding waste of electric energy; and since the surface coating of the substrate is relatively thin, if the drying fan 241 is continuously driven to output with a large current, it will not only cause energy waste, but also may cause unnecessary damage to the surface coating of the substrate. Therefore, through this setting, the current output of the drying fan 241 can be reduced, so that it can achieve effective control of electric energy while ensuring the drying effect of the surface coating of the substrate; Furthermore, in the process of adjusting the distance between the adjusting roller 321 and the coating roller 322, when the coating on the substrate surface is thicker, when the adjusting plate 231 is driven to move to the left by the electric telescopic device 232, the adjusting roller 321 is driven to rotate counterclockwise and the distance between the coating rollers 322 is increased. In the process of the adjusting plate 231 moving to the left, the flexible ventilation coil 244 is pulled to move synchronously, thereby increasing the air outlet range of the dry airflow and effectively increasing the drying area of ​​the substrate, ensuring that the dry airflow can evenly and efficiently cover the entire substrate surface, thereby improving the drying effect of the substrate surface coating, and through this setting, the air volume can be automatically adjusted according to the thickness of the substrate surface coating, and the air outlet range of the dry airflow is automatically adjusted by the synchronous movement of the flexible ventilation coil 244, thereby realizing effective control of the substrate drying area, and the applicability of the coating machine is further improved through this setting, so that it can be flexibly adjusted according to the actual thickness of the substrate surface coating.
