Description

Technical Field

[0001] This utility model relates to the field of louver processing technology, specifically to an automatic feeding device for aluminum cores of PVC louver blades. Background Technology

[0002] As the core support structure of the louver blades, the aluminum core keeps the blades flat and stable, ensuring that the louvers operate normally during opening and closing, preventing problems such as bending and deformation, and extending the service life of the louvers.

[0003] Traditional aluminum core feeding devices have significant drawbacks in practical applications: due to the lack of effective positioning and guiding structures, the aluminum core is prone to tilting during transport. When the tilted aluminum core enters the extruder die, it is difficult to accurately align with the die inlet, leading not only to obstructed transport but also potential bending and deformation due to pressure against the die wall. This problem directly affects the quality of subsequent PVC blade wrapping, resulting in defects such as blade bending and dimensional deviations. In severe cases, it can even reduce the overall structural strength and lifespan of the louvers, increasing scrap rates and rework costs during production. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for aluminum core blades of PVC louvers. The device stores the aluminum core blades in a storage frame, and the internal structure of the storage frame ensures that the aluminum cores are neatly stacked. Then, a flat pushing component pushes the aluminum core blades towards the conveying rollers. Subsequently, two sets of conveying rollers vertically convey the aluminum core blades to ensure that they are neatly inserted into the extruder mold, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for aluminum core blades in PVC louvers, comprising: device body; The device body includes a fixed frame fixed on the extruder, and a storage frame for storing aluminum blade cores for louvers is movably arranged in the inner cavity of the fixed frame. A pushing component for pushing the aluminum blade cores is arranged on one side of the storage frame. The fixed frame has a movable frame movably installed inside its cavity. Two sets of conveying rollers for translating the aluminum core of the blade are rotatably installed inside the movable frame. The movable frame is equipped with a drive assembly for driving the conveying rollers. The storage frame has a through groove on the side near the movable frame. The conveying roller passes through the through groove and extends into the cavity of the storage frame. Both the fixed frame and the storage frame have discharge ports on the same side.

[0006] Preferably, the push assembly is fixed to a mounting plate on the outside of the storage frame, and two sets of electric push rods are fixedly installed on the mounting plate. The movable end of the electric push rod extends through the inner cavity of the storage frame and is fixed with a push plate.

[0007] Preferably, the drive assembly includes a drive motor fixed to the top of the movable frame, the output shaft of the drive motor passing through the inner cavity of the movable frame and fixed with a drive pulley, a driven pulley fixed on the conveying roller, and a synchronous belt drivingly connecting the drive pulley and the outer side of the driven pulley.

[0008] Preferably, two sets of slide rails are fixed to the bottom of the inner cavity of the fixed frame, and a slide block is slidably disposed on the top of the slide rails, the slide block being fixed to the outside of the movable frame.

[0009] Preferably, a support spring is fixed inside the fixed frame, and the movable end of the support spring is fixed to the outside of the slide.

[0010] Preferably, a buckle plate is fixed to the outer side of the mounting plate, and fasteners that cooperate with the buckle plate are fixed to both sides of the fixing frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a flat-push assembly to apply pressure to the aluminum blade cores stored in the storage frame, ensuring that the aluminum blade cores are neatly arranged. Then, a drive assembly synchronously drives two sets of conveying rollers, facilitating the feeding of the aluminum blade cores one by one using the conveying rollers. At the same time, the aluminum blade cores are kept vertical during the conveying process to prevent them from tilting when entering the extruder, which would affect the subsequent processing quality.

[0012] This utility model uses a support spring to facilitate buffering of the movable frame. When the storage frame is installed in the fixed frame, the conveyor roller exerts a certain squeezing force on the aluminum core of the blade when it is used with the flat push assembly. This provides frictional power for the conveyor roller to drive the aluminum core of the blade. At the same time, it can also prevent the flat push plate from excessively squeezing the aluminum core of the blade by using the support spring to play a buffering and protective role.

[0015] 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.

[0016] This utility model provides, for example Figures 1-4 The automatic feeding device for aluminum core blades of PVC venetian blinds shown includes: device body; The device body includes a fixed frame 1 fixed on the extruder, and a storage frame 2 for storing the aluminum core of the louver blade is movably arranged in the inner cavity of the fixed frame 1. A pushing component 3 for pushing the aluminum core of the blade is arranged on one side of the storage frame 2. The inner cavity of the fixed frame 1 is movably provided with a movable frame 4. The inner cavity of the movable frame 4 is rotatably equipped with two sets of conveying rollers 5 for translating the aluminum core of the blade. The movable frame 4 is provided with a drive assembly 6 for driving the conveying rollers 5. The storage frame 2 is provided with a through groove 7 on the side near the movable frame 4. The conveying rollers 5 pass through the through groove 7 and extend into the inner cavity of the storage frame 2. Both the fixed frame 1 and the storage frame 2 have discharge ports 8 on the same side, and the device body is also equipped with a control system. The flat push assembly 3 applies pressure to the aluminum blade cores stored in the storage frame 2 to ensure that the aluminum blade cores are neatly arranged. Then, the drive assembly 6 drives the two sets of conveying rollers 5 synchronously, so that the aluminum blade cores can be fed one by one by the conveying rollers 5. At the same time, the aluminum blade cores are kept vertical during the conveying process to prevent them from tilting when entering the extruder, which would affect the subsequent processing quality.

[0017] Among them, such as Figure 1-2 As shown: The flat push assembly 3 is fixed on the mounting plate 31 on the outside of the storage frame 2. Two sets of electric push rods 32 are fixedly installed on the mounting plate 31. The movable end of the electric push rod 32 passes through the inner cavity of the storage frame 2 and is fixed with the flat push plate 33. The flat push plate 33 is moved by the electric push rod 32, and the flat push plate 33 is used to squeeze and limit the aluminum core of the blade to ensure that the aluminum core of the blade is squeezed and moved towards the discharge port 8.

[0018] Furthermore, such as Figure 4 As shown: The drive assembly 6 includes a drive motor 61 fixed to the top of the movable frame 4. The output shaft of the drive motor 61 passes through the inner cavity of the movable frame 4 and is fixed with a drive pulley 62. A driven pulley 63 is fixed on the conveying roller 5. A synchronous belt 64 is connected to the outer side of the drive pulley 62 and the driven pulley 63. The drive motor 61 drives the drive pulley 62 to rotate, and then the synchronous belt 64 makes the driven pulley 63 rotate synchronously with the conveying roller 5, so that the aluminum core of the blade can be conveyed by friction using the conveying roller 5.

[0019] Preferred, such as Figure 3-4 As shown: Two sets of slide rails 9 are fixed at the bottom of the inner cavity of the fixed frame 1. A slide block 10 is slidably provided on the top of the slide rail 9. The slide block 10 is fixed on the outside of the movable frame 4. By sliding the slide block 10 on the slide rail 9, it is convenient to maintain the stability of the movable frame 4 and ensure that the conveying roller 5 moves vertically to the storage frame 2.

[0020] It is worth noting that, such as Figure 4 As shown: A support spring 11 is fixed inside the fixed frame 1. The movable end of the support spring 11 is fixed to the outside of the slide block 10. With the cooperation of the support spring 11, the movable frame 4 can be buffered. When the storage frame 2 is installed in the fixed frame 1, the conveying roller 5 exerts a certain squeezing force on the aluminum core of the blade when it is in conjunction with the flat push assembly 3. This provides frictional power for the conveying roller 5 to drive the aluminum core of the blade. At the same time, it can also prevent the flat push plate 33 from excessively squeezing the aluminum core of the blade. The support spring 11 plays a buffering and protection role.

[0021] In a further preferred embodiment, such as Figure 1-2 As shown: A buckle plate 12 is fixed to the outside of the mounting plate 31, and buckles 13 that cooperate with the buckle plate 12 are fixed to both sides of the fixing frame 1. By cooperating with the buckle plate 12, the mounting plate 31 can be easily installed and fixed, thereby fixing the storage frame 2 and making it easy to disassemble and assemble the storage frame 2.

[0022] In practical use, the aluminum blade cores are placed in the storage frame 2, and then the storage frame 2 is inserted from one end of the fixed frame 1. At the same time, the mounting plate 31 and the storage frame 2 are fixed by the buckle 13 and the buckle plate 12. The electric push rod 32 drives the flat push plate 33 to move in the storage frame 2, so that the aluminum blade cores are closely arranged, while ensuring that each group of aluminum blade cores is in a vertical state. At this time, the movable frame 4, supported by the support spring 11, makes the conveying roller 5 pass through the through groove 7 and contact the aluminum blade cores. Then, the drive motor 61 drives the drive pulley 62 to rotate. The drive pulley 62 drives the driven pulley 63 to rotate through the synchronous belt 64, so that the two groups of conveying rollers 5 rotate synchronously. The conveying roller 5 drives the aluminum blade cores through the discharge port 8 by friction and is conveyed into the mold in the extruder.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
