Description

Technical Field

[0001] This utility model relates to the field of building materials processing technology, and in particular to an automatic film coating machine for aluminum core blades of PVC louvers. Background Technology

[0002] As the core component of louvers, the quality of the surface coating of aluminum core blades directly affects the product's weather resistance, aesthetics, and service life.

[0003] Existing aluminum core blade laminating equipment typically includes an unwinding mechanism, a pressing mechanism, and a rewinding mechanism. The pressing mechanism often employs a fixed upper and lower roller structure, with a motor driving the rollers to rotate and bond the laminating material to the aluminum core blade under pressure. When dealing with aluminum core blades of varying thicknesses and different types of laminating materials, some equipment suffers from a relatively fixed distance between the upper and lower pressing rollers. This can lead to several issues during the actual laminating process. For thinner aluminum core blades and softer laminating materials, excessive pressure can cause deformation of the aluminum core blades and damage to the laminating material. Conversely, for thicker aluminum core blades and more resilient laminating materials, insufficient pressure may result in uneven and firm laminating, leading to problems such as air bubbles and loose adhesion, affecting product quality. Furthermore, after the laminating material is unwound, if the aluminum core blade is too short or the laminating process requires cutting, excess laminating material will scatter, affecting the cleanliness of the production environment, wasting resources, and increasing production costs. Therefore, an automatic laminating machine for aluminum core blades used in PVC blinds is proposed to address these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic laminating machine for aluminum core blades of PVC blinds, which aims to improve the problem that the pressure of the upper and lower pressing rollers cannot be adjusted in the existing technology, resulting in uneven and weak lamination.

[0007] The pressure regulating assembly includes a fixing block, which is fixedly connected to the inner side of the fixing frame.

A fixing bolt is provided in the middle of the clamping block, and an upper pressure roller is rotatably connected to the middle of the clamping block.

[0008] As a further description of the above technical solution:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of an automatic laminating machine for aluminum core blades of PVC blinds, including a mounting frame 1. A fixing frame 20 is fixedly connected to the top of the mounting frame 1, and a lower pressing roller 16 is rotatably connected to the middle of the mounting frame 1. A pressure regulating component is installed on the fixing frame 20, and a recycling component is installed in the middle of the mounting frame 1. The pressure regulating component includes a fixing block 18, which is fixedly connected to the inner side of the fixing frame 20. A handle 21 is threadedly connected to the middle of the fixing block 18, and a clamping block 17 is fixedly connected to the bottom of the handle 21. A fixing bolt 19 is provided in the middle of the clamping block 17, and an upper pressing roller 15 is rotatably connected to the middle of the clamping block 17. The upper pressing roller 15 is first placed in the middle of the clamping block 17, and then the clamping block 17 is fixed by the fixing bolt 19, so that the upper pressing roller 15 is firmly fixed inside the clamping block 17 to prevent it from falling off during operation and affecting the laminating efficiency. A drive shaft 4 is rotatably connected to the middle of the mounting frame 1. A limiting shaft 13 is fixedly connected to the outside of the drive shaft 4. A guide rail 2 is provided in the middle of the limiting shaft 13. The drive shaft 4 rotates to drive the guide rail to work, conveying the filter element blades to the pressing area for coating. An unwinding roller 3 is placed on the top of the fixing block 18. A fixing roller 5 is fixedly connected to the outside of the fixing block 18. The coating material is wound around the outside of the unwinding roller 3. In use, one end of the coating material is pulled out and passed through the fixing roller 5, and then attached to the outside of the aluminum core blades. Under the action of the upper and lower pressing rollers, the film is coated. An electric push rod 6 is fixedly connected to the outside of the fixing frame 20. A connecting shaft 12 is fixedly connected to the output end of the electric push rod 6. A cutting blade 14 is fixedly connected to the outside of the connecting shaft 12. The fixing frame 20 has a slot 22 in the middle. The connecting shaft 12 is slidably connected to the middle of the slot 22. The electric push rod 6 pushes the connecting shaft 12 and the cutting blade 14 to slide downward in the slot 22. After cutting, the electric push rod 6 retracts to drive the cutting blade 14 to slide upward, so that the cutting blade 14 is on the guide rail for easy replacement.

[0032] Reference Figure 1 and Figure 2 The recycling assembly includes a connecting plate 10, which is fixedly connected to the inner side of the mounting frame 1. A drive motor 7 is fixedly connected to the outside of the connecting plate 10. A pulley 8 is fixedly connected to the output end of the drive motor 7, and a recycling roller 11 is fixedly connected to the middle of the pulley 8. A belt 9 is fitted around the outside of the pulley 8. When the drive motor 7 is started, one of the pulleys 8 is driven to rotate. Under the transmission of the belt 9, the other pulley 8 is driven to rotate, causing the recycling roller 11 to rotate and recycle the cut film material, avoiding material discarding and waste, and saving resources.

[0033] Working principle: The coating material is placed outside the unwinding roller 3. The drive shaft 4 is activated to rotate the limiting shaft 13 and the guide rail 2, causing the aluminum core blade to enter the coating area along a predetermined path, ensuring the accuracy of the coating position. By rotating the handle 21, the clamping block 17 moves up and down, thereby adjusting the distance and pressure between the upper pressing roller 15 and the lower pressing roller 16. When the aluminum core blade passes between the upper and lower pressing rollers 16, the coating material is tightly adhered to the surface of the aluminum core blade under pressure.

[0034] When it is necessary to cut the excess coating material of the coated aluminum core blade, the electric push rod 6 pushes the connecting shaft 12 to slide in the slot 22. The connecting shaft 12 drives the cutting blade 14 to move downward to cut the coating material. At the same time, the drive motor 7 is started to drive one of the pulleys 8 to rotate. Under the transmission of the belt 9, the other pulley 8 is driven to rotate, so that the recycling roller 11 rotates to recycle and wind up the excess coating material after coating.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
