Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, specifically to an aluminum foil guiding mechanism for an aluminum-plastic packaging machine. Background Technology

[0002] In the current packaging process of pharmaceuticals, food, and some electronic products, aluminum-plastic packaging machines play a crucial role. With its advantages of good barrier properties, moisture resistance, and aesthetics, aluminum-plastic packaging has become the preferred packaging method for many products. As an important component of aluminum-plastic packaging, the precise guidance of aluminum foil in the packaging process is directly related to packaging quality and production efficiency. However, the existing aluminum foil guiding mechanism of aluminum-plastic packaging machines still has some problems in use: First, the existing guiding mechanism lacks a structure for adjusting the tension, which leads to unstable tension of the aluminum foil during the conveying process. It is easy for the aluminum foil to become loose or too tight. Looseness will cause the aluminum foil to wrinkle, while excessive tightness may cause the aluminum foil to break. Secondly, the existing guide shaft installation structure is designed to be too complex, resulting in cumbersome and time-consuming operation steps when disassembling and installing the guide rollers, which in turn reduces the convenience of overall maintenance of the guide mechanism. Utility Model Content

[0003] To address the issues of existing guiding mechanisms lacking tension adjustment functionality and having poor overall structural maintenance convenience, the purpose of this utility model is to provide an aluminum foil guiding mechanism for aluminum-plastic packaging machines.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: an aluminum foil guiding mechanism for an aluminum-plastic packaging machine, including a base, a first mounting seat symmetrically fixedly mounted on the upper surface of the base, a first guide roller provided on one side of the first mounting seat, a guide shell fixedly connected to one side of the base, an adjustment mechanism provided inside the guide shell, a second mounting seat provided on one side of the adjustment mechanism, a second guide roller provided on one side of the second mounting seat, quick-connect components provided between the second mounting seat and the second guide roller and between the first mounting seat and the first guide roller, the adjustment mechanism including a servo motor, the servo motor fixedly mounted inside the guide shell, a screw fixedly connected to the output end of the servo motor, the top end of the screw rotatably connected to the inner wall of the guide shell, a slider threaded on the outer surface of the screw, connecting rods symmetrically fixedly connected to both sides of the slider, limiting grooves symmetrically opened on both sides of the guide shell for use with the connecting rods, the connecting rods slidingly connected to the limiting grooves, and the second mounting seat fixedly mounted on one side of the connecting rods.

[0005] Preferably, the quick-installation assembly includes a bearing housing, which is rotatably disposed on one side of the second mounting base. A plate is movably inserted into one side of the bearing housing, and the plate is fixedly installed on one side of the second guide roller. A positioning plate is fixedly connected to the outer surface of the bearing housing. A limit pin is movably inserted into the plate and the bearing housing together. A bolt is threadedly connected between the limit pin and the positioning plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application, by setting an adjustment mechanism, can flexibly adjust the tension of the aluminum foil according to the actual conveying and guiding requirements. This can avoid the aluminum foil from becoming loose and wrinkled due to insufficient tension, and also prevent the aluminum foil from being stretched and broken due to excessive tension. This effectively ensures the stable guiding effect of the guiding mechanism on the aluminum foil, while reducing material consumption. 2. This application achieves the fixing and disassembly of the guide roller by setting up quick-installation components and adopting a simplified installation method of plug-in and bolt connection. This design greatly simplifies the disassembly and assembly steps of the guide roller during the maintenance of the guide mechanism, shortens the time spent on a single maintenance, significantly improves the overall maintenance convenience of the guide mechanism, and helps to improve the continuous operation efficiency of the equipment.

[0013] 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.

[0014] Example: Figure 1-4 As shown, this utility model provides an aluminum foil guiding mechanism for an aluminum-plastic packaging machine, including a base 1. Mounting plates 9 are symmetrically fixed to both sides of the base 1. The symmetrically fixed mounting plates 9, together with mounting components, facilitate the overall installation of the guiding mechanism onto the aluminum-plastic packaging machine, reducing the assembly difficulty of the mechanism and equipment and improving assembly efficiency. A first mounting seat 4 is symmetrically fixed to the upper surface of the base 1. A first guide roller 6 is provided on one side of the first mounting seat 4. The symmetrically fixed first mounting seat 4 provides a stable mounting foundation for the first guide roller 6. The first guide roller 6 can initially guide the aluminum foil direction, laying the foundation for subsequent aluminum foil conveying.

[0015] A guide shell 11 is fixedly connected to one side of the base 1. An adjustment mechanism 2 is provided inside the guide shell 11. The adjustment mechanism 2 can flexibly adjust the tension of the aluminum foil, solving the problem of unstable tension in traditional mechanisms. A second mounting seat 10 is provided on one side of the adjustment mechanism 2. A second guide roller 7 is provided on one side of the second mounting seat 10. The second mounting seat 10 serves as the connecting carrier between the adjustment mechanism 2 and the second guide roller 7. Through the cooperation of the second guide roller 7 and the first guide roller 6, the aluminum foil conveying path can be optimized. At the same time, combined with the adjustment of the adjustment mechanism 2, the aluminum foil tension can be precisely controlled, avoiding the aluminum foil from becoming loose and wrinkled or breaking due to excessive tightness.

[0016] The outer surfaces of the first guide roller 6 and the second guide roller 7 are both fixedly fitted with anti-slip sleeves 5. The anti-slip sleeves 5 increase the friction between the guide rollers and the aluminum foil, effectively preventing the aluminum foil from slipping during the conveying process, which can cause unstable conveying speed or path deviation. The second mounting base 10 and the second guide roller 7 and the first mounting base 4 and the first guide roller 6 are both provided with quick-installation components 3. There are three sets of quick-installation components 3, and the internal structures of the three sets of quick-installation components 3 are the same. The use of quick-installation components 3 and the identical structure of the three sets of quick-installation components 3 not only ensure the universality of the guide roller disassembly and assembly structure, but also greatly simplify the disassembly and assembly steps of the guide roller and shorten the maintenance time.

[0017] The adjustment mechanism 2 includes a servo motor 22, which is fixedly installed inside the guide shell 11. The servo motor 22 serves as the power source for the adjustment mechanism 2. A screw 25 is fixedly connected to the output end of the servo motor 22. The fixed connection between the output end of the servo motor 22 and the screw 25 can convert the rotational motion of the servo motor 22 into the synchronous rotation of the screw 25. The top end of the screw 25 is rotatably connected to the inner wall of the guide shell 11, ensuring the coaxiality of the screw 25 during rotation.

[0018] The outer surface of the screw 25 is threaded with a slider 24, which is slidably connected to the inner wall of the guide shell 11. When the screw 25 rotates, the threaded engagement can drive the slider 24 to move along the axis of the screw 25. Connecting rods 23 are symmetrically fixed to both sides of the slider 24. The connecting rods 23 symmetrically fixed to both sides of the slider 24 can synchronously transmit the displacement of the slider 24 to the second mounting base 10, realizing the stable transmission of force and displacement. The guide shell 11 has symmetrically opened limiting grooves 26 for use with the connecting rods 23. The connecting rods 23 are slidably connected to the limiting grooves 26. The limiting grooves 26 opened on both sides of the guide shell 11 are slidably engaged with the connecting rods 23, which not only limits the movement direction of the connecting rods 23, but also prevents the connecting rods 23 from shaking when moving.

[0019] The second mounting base 10 is fixedly installed on one side of the connecting rod 23. Fixing the second mounting base 10 to one side of the connecting rod 23 allows the displacement of the connecting rod 23 to be directly transmitted to the second mounting base 10, thereby driving the second guide roller 7 to adjust its position synchronously, ensuring the accuracy of aluminum foil tension adjustment.

[0020] The quick-assembly assembly 3 includes a bearing seat 33, which is rotatably mounted on one side of the second mounting base 10. This rotatable mounting allows the bearing seat 33 to rotate synchronously with the second guide roller 7, reducing frictional resistance during rotation. A magnetic plate 34 is movably inserted into one side of the bearing seat 33, and the bearing seat 33 is a magnetic base. The insert plate 34 and bearing seat 33 are magnetically connected, and the insert plate 34 is fixedly mounted on one side of the second guide roller 7. This magnetic connection allows for rapid initial positioning and connection between the second guide roller 7 and the bearing seat 33, reducing assembly difficulty. Furthermore, the magnetic structure provides initial pre-fixing force, preventing misalignment between the insert plate 34 and bearing seat 33 during subsequent bolt installation, thus improving assembly efficiency.

[0021] A positioning plate 32 is fixedly connected to the outer surface of the bearing housing 33. The positioning plate 32 fixed to the outer surface of the bearing housing 33 provides an installation base for the bolt 35. The insert plate 34 and the bearing housing 33 are movably inserted into the limiting pin 31. The insert plate 34 and the bearing housing 33 are positioned by the insertion of the limiting pin 31, which can further ensure the coaxiality and positional accuracy of the two and avoid the offset after the second guide roller 7 is installed. The limiting pin 31 and the positioning plate 32 are threadedly connected by a bolt 35. The limiting pin 31 and the positioning plate 32 are threadedly connected by the bolt 35, which can realize the firm fixation of the insert plate 34 and the bearing housing 33. At the same time, the detachable design of the bolt 35 facilitates the subsequent disassembly and maintenance of the guide roller, taking into account both connection stability and maintenance convenience.

[0022] Working principle: The guide mechanism is installed at the preset station of the packaging machine by the mounting plates 9 on both sides of the base 1 in conjunction with the mounting components. The base 1 provides stable support.

[0023] The first guide roller 6 is mounted on the first mounting seat 4 of the base 1 via the quick-mount assembly 3, and the second guide roller 7 is mounted on the second mounting seat 10 via the quick-mount assembly 3. The three quick-mount assemblies 3 are magnetically positioned by the bearing seat 33 and the insert plate 34, the limit pin 31 is inserted, and the bolt 35 is locked to the positioning plate 32 to fix the initial position of the guide roller.

[0024] After the packaging machine starts running, the aluminum foil is output from the unwinding mechanism and first contacts the first guide roller 6. The anti-slip sleeve 5 on its outer surface increases the friction to prevent slippage. The bearing seat 33 in the quick-assembly assembly 3 rotates flexibly with the guide roller to reduce friction and make the aluminum foil smoothly conveyed to the second guide roller 7.

[0025] If the aluminum foil is too loose or too tight during transport, the adjustment mechanism 2 will be activated, and the external system will drive the servo motor 22 inside the guide shell 11 to rotate the screw 25.

[0026] The slider 24 moves along the screw 25 under the limit of the inner wall of the guide shell 11, and drives the second mounting seat 10 and the second guide roller 7 to move through the connecting rod 23 along the limiting groove 26, thereby realizing tension adjustment.

[0027] After tension adjustment, the second guide roller 7 enhances the fit through the anti-slip sleeve 5, and the bearing seat 33 rotates in coordination with it, working together with the first guide roller 6 to guide the aluminum foil to the subsequent process, ensuring that the aluminum foil is free from deviation, wrinkles or breakage.

[0028] When maintaining the guide roller, unscrew the bolt 35, pull out the limit pin 31, and overcome the magnetic attraction between the bearing seat 33 and the insert plate 34 to disassemble it.

[0029] When installing a new device, the process is reversed. Three sets of quick-installation components simplify the operation and reduce the time required.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
