Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, specifically to a film loading and unloading mechanism for a laminating machine. Background Technology

[0002] Laminating machines are core equipment in packaging printing, electronic material processing and other fields. Their core function is to laminate film materials such as PET optical film with paper, plastic sheets and metal foil through heating, pressing and bonding to form finished products with waterproof, scratch-proof, light-proof or decorative functions. They are widely used in the packaging production industry of food, pharmaceutical and electronics industries.

[0003] Existing film loading and unloading mechanisms in laminating machines are mostly used during the roll replacement stage after the film roll has been used up. They are involved in the feeding, roll changing, and initial positioning of the film material. However, existing film loading and unloading mechanisms in laminating machines mostly use bolt locking and knob adjustment, which significantly reduces efficiency when changing the film by adjusting each screw or knob individually. Moreover, the roll can only be manually changed after the machine is stopped, resulting in a roll change time of several minutes to tens of minutes, which greatly affects the production efficiency of the product. Therefore, we propose a film loading and unloading mechanism for laminating machines. Utility Model Content

[0004] The purpose of this utility model is to provide a film loading and unloading mechanism for a laminating machine, so as to solve the problem mentioned in the background art that the existing film loading and unloading mechanisms for laminating machines mostly use bolt locking and knob adjustment, which significantly reduces the efficiency when changing the film by adjusting each screw or knob one by one. Moreover, the machine must be stopped before the roll can be changed manually, which takes several minutes to tens of minutes to change the roll, greatly affecting the production efficiency of the product.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a film loading and unloading mechanism for a laminating machine, comprising: a laminating machine main frame, a parallel slide rail fixedly connected to the top of the laminating machine main frame, a slider slidably connected to the parallel slide rail, a quick-release assembly fixedly connected to the slider, a roll detachably connected to the quick-release assembly, a roll of film sleeved on the roll, the quick-release assembly for quick disassembly and replacement of the roll, and limiting components at both ends of the roll for axial limiting of the roll of film.

[0006] The quick-release assembly consists of two sets, each with a detachable roller connected to it, and each roller is fitted with a film.

[0007] The main frame of the film-coating machine is fixedly connected to a placement plate, a telescopic rod is fixedly connected to the placement plate, a connecting rod is fixedly connected to the output end of the telescopic rod, and the other side of the connecting rod is fixedly connected to a quick-release assembly.

[0008] The quick-release assembly includes a mounting base fixedly connected to the slider, with a placement groove on the mounting base. Both ends of the reel are placed in the placement groove. A fixing rod is fixedly connected to the top of the mounting base, and a locking block is rotatably connected to the fixing rod. The area formed by the locking block and the mounting base matches the ends of the reel. It also includes:

[0009] A strip groove is provided at the end of the locking block away from the fixed rotating rod. A rotating groove is provided on the mounting base. The opening of the rotating groove matches the size of the strip groove. A T-shaped locking shaft is rotatably engaged in the rotating groove. The T-shaped end of the T-shaped locking shaft matches the strip groove.

[0010] The limiting component includes a limiting ring that is slidably connected to the roll. A rubber pad is provided on the side of the limiting ring closest to the roll, and a fixing mechanism is fixedly connected to the side of the limiting ring away from the roll.

[0011] The fixing mechanism includes a fixed base fixedly connected to a limiting ring, a fixed rod fixedly connected to the fixed base, a rotating base rotatably connected to the fixed base, an arc-shaped groove on the rotating base, the fixed rod passing through the arc-shaped groove and slidingly engaging with the inner wall of the arc-shaped groove, a first rotating rod fixedly connected to the rotating base, a movable arm rotatably connected to the first rotating rod, a second rotating rod fixedly connected to the other end of the movable arm, and a pressing block rotatably connected to the second rotating rod; it also includes:

[0012] A fixed ring is attached to which rotating rods three are evenly fixed along the circumference. The rotating rods three are rotatably connected to the extrusion block. The side of the extrusion block facing the center of the fixed ring is used to fit against the outer wall of the roll. A rotating cover is fixedly connected to the outside of the rotating seat. The rotating cover drives the rotating seat to rotate.

[0013] Two quick-release components are fixed at both ends of the slider. When the slider slides, it can drive the two quick-release components to slide synchronously along the parallel slide rail. The rollers of the two quick-release components are alternately in the working position and the film-to-be-replaced position.

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1 to 6This utility model provides a technical solution: a film loading and unloading mechanism for a laminating machine, comprising: a laminating machine main frame 1, a parallel slide rail 2 fixedly connected to the top of the laminating machine main frame 1, a slider 3 slidably connected to the parallel slide rail 2, a quick-release assembly 4 fixedly connected to the slider 3, a roller 5 detachably connected to the quick-release assembly 4, a roll of film 6 sleeved on the roller 5, the quick-release assembly 4 for quick disassembly and replacement of the roller 5, and limiting components 7 at both ends of the roller 5 for axial limiting of the roll of film 6. The laminating machine main frame 1 is made of welded steel pipe with a rust-proof paint coating to ensure the overall rigidity of the mechanism and prevent vibration during high-speed operation. The parallel slide rail 2 is made of 304 stainless steel with a dovetail-shaped cross-section. The slider 3 is made of aluminum alloy and hard anodized to reduce sliding resistance and extend the service life of the parallel slide rail 2. The spool 5 is an air-expanding shaft, adapted to the core diameter of the 3-8 inch roll film 6, providing clamping force to prevent the roll film 6 from sliding relative to the spool 5. The quick-release assembly 4 allows for quick disassembly and replacement of the spool 5 without the need for tools, reducing manual labor intensity. The limiting assembly 7 can slide and lock along the axial direction of the spool 5, preventing the roll film 6 from slipping and causing misalignment during lamination, thus improving lamination alignment accuracy.

[0026] The quick-release assembly 4 consists of two sets, each detachably connected to a roller 5. A roll of film 6 is fitted onto each roller 5. The two sets of quick-release assemblies 4 are symmetrically distributed along the length of the slider 3, with a center-to-center distance of 200-400mm. This adapts to the layout of the laminating machine's working positions and film-changing positions. The two sets of quick-release assemblies 4 are identical in structure and size and can be used interchangeably, reducing component replacement costs. Each set of quick-release assemblies 4 is connected to a roller 5 via the same detachable structure. The two sets of rollers 5 can accommodate the same or different specifications of film 6, meeting the needs of multi-variety, small-batch production. The installation and removal of the rollers 5 in the two sets of quick-release assemblies 4 do not interfere with each other. When one set is changing rolls, the other set can continue to work normally with the laminating machine, achieving a one-in-one-out alternating mode. This avoids traditional single-station downtime and increases the continuous production time of the laminating machine.

[0027] A placement plate 8 is fixedly connected to the top of the main frame 1 of the laminating machine. A telescopic rod 9 is fixedly connected to the placement plate 8. A connecting rod 10 is fixedly connected to the output end of the telescopic rod 9. The other side of the connecting rod 10 is fixedly connected to the quick-release assembly 4. The placement plate 8 is made of Q235 steel to ensure that the telescopic rod 9 is installed flat and subjected to stable force. The telescopic rod 9 is an electric push rod driven by a servo motor. The connecting rod 10 at its output end is rigidly fixed to the mounting base 41 of the quick-release assembly 4, which can drive the slider 3 to accurately and quickly switch positions. By extending and retracting the telescopic rod 9, the slider 3 can be pushed to slide along the parallel slide rail 2, thereby realizing the switching of the position of the film roll 6 and realizing the replacement of the film roll 6 without stopping the machine.

[0028] The quick-release assembly 4 includes a mounting base 41 fixedly connected to the slider 3, a placement groove 42 on the mounting base 41, both ends of the scroll 5 are placed in the placement groove 42, a fixed rotating rod 43 is fixedly connected to the top of the mounting base 41, a locking block 44 is rotatably connected to the fixed rotating rod 43, and the area formed by the locking block 44 and the mounting base 41 matches the end of the scroll 5; it also includes a strip groove 45, which is opened at the end of the locking block 44 away from the fixed rotating rod 43, a rotating groove 46 on the mounting base 41, the opening of the rotating groove 46 matches the size of the strip groove 45, and a T-shaped locking shaft 47 is rotatably engaged in the rotating groove 46, the T-shaped end of the T-shaped locking shaft 47 matches the strip groove 45. The mounting base 41 is made of 45# steel and is subjected to overall quenching treatment to effectively ensure wear resistance and dimensional stability, and extend the service life of the component. The placement groove 42 allows the end of the reel 5 to be placed stably without radial wobbling. The top of the mounting base 41 is fixedly connected to a 304 stainless steel fixing rod 43 by welding. The locking block 44 is an arc-shaped locking block 44. The inner wall of the locking block 44 is pasted with wear-resistant rubber, which not only enhances the fit with the reel 5, but also avoids direct metal-to-metal contact wear. The locking block 44 can rotate around the fixing rod 43. When closed, it can surround and fit the end of the reel 5 with the mounting base 41 to achieve radial positioning.

[0029] In use, place the roll 5 into the placement slot 42, rotate the top arc-shaped locking block 44 around the fixed rotating rod 43 to close it, forming a ring-like positioning with the placement slot 42. At this time, insert the T-shaped locking shaft 47 into the rotating slot 46 through the strip groove 45. Then rotate the T-shaped locking shaft 47 to make it lock into the rotating slot 46, locking the locking block 44 through axial locking force, thereby locking the roll 5. When it is necessary to disassemble the roll 5 to replace the film 6, the locking block 44 can be opened and the roll 5 can be removed by reversing the process.

[0030] The limiting component 7 includes a limiting ring 71 that slides on the reel 5. A rubber pad 72 is provided on the side of the limiting ring 71 closest to the film roll 6, and a fixing mechanism 73 is fixedly connected to the side of the limiting ring 71 furthest from the film roll 6. The inner diameter of the limiting ring 71 is clearance-fitted with the outer diameter of the reel 5 to ensure smooth sliding without jamming. The limiting ring 71 has a thickness of 15-25mm to ensure its rigidity. The rubber pad 72 is made of nitrile rubber or silicone, which avoids scratching or indenting the surface of the film roll 6 caused by traditional rigid limiting mechanisms, making it particularly suitable for sensitive film materials such as optical films and food packaging films. The fixing mechanism 73 provides axial thrust resistance, fixing the limiting ring 71 to the reel 5 and ensuring that the film roll 6 does not move axially during high-speed unwinding or tension fluctuations, thus ensuring lamination alignment accuracy.

[0031] The fixing mechanism 73 includes a fixing seat 74 fixedly connected to the limiting ring 71, a fixing rod 75 fixedly connected to the fixing seat 74, a rotating seat 76 rotatably connected to the fixing seat 74, an arc-shaped groove 77 on the rotating seat 76, the fixing rod 75 passing through the arc-shaped groove 77 and slidingly engaging with the inner wall of the arc-shaped groove 77, a first rotating rod 78 fixedly connected to the rotating seat 76, a movable arm 79 rotatably connected to the first rotating rod 78, a second rotating rod 710 fixedly connected to the other end of the movable arm 79, and a pressing block 711 rotatably connected to the second rotating rod 710; it also includes a fixing ring 712, a third rotating rod 713 evenly fixedly connected to the fixing ring 712 along the circumference, the third rotating rod 713 rotatably connected to the pressing block 711, the side of the pressing block 711 facing the center of the fixing ring 712 is used to fit against the outer wall of the roll 5, and a rotating cover 714 fixedly connected to the outside of the rotating seat 76, the rotating cover 714 driving the rotating seat 76 to rotate.

[0032] In use, rotating the rotating cover 714 counterclockwise causes the rotating seat 76 to rotate counterclockwise under the limit of the fixed rod 75, thereby causing the movable arm 79 to move towards the fixed ring 712 with the rotating rod 78 as the fulcrum. Under the combined action of the rotating rod 710 and the rotating rod 713, the extrusion block 711 retracts inward with the rotating rod 713 as the fulcrum, realizing the tight fit or separation of the extrusion block 711 and the outer wall of the roll 5. This allows the fixing mechanism 73 to uniformly and stably extrude the roll 5 from multiple directions, thereby completing the locking and unlocking of the limit ring 71 on the roll 5, greatly improving the reliability and stability of the fixation. When it is necessary to change the position, the rotating cover 714 can be rotated clockwise to quickly loosen it. At this time, the limit ring 71 can be slid to accommodate the limiting fixation of different specifications of roll film 6.

[0033] Two sets of quick-release components 4 are fixed at both ends of the slider 3. When the slider 3 slides, it can drive the two sets of quick-release components 4 to slide synchronously along the parallel slide rail 2, and the rolls 5 of the two sets of quick-release components 4 alternately occupy the working position and the film-to-be-changed position. The rolls 5 of the two sets of quick-release components 4 correspond to the working position and the film-to-be-changed position respectively. The axis of the roll 5 in the working position can ensure smooth film material transportation, and the film-to-be-changed position is far away from the main machine's working area, allowing operators to safely change rolls. When the film roll 6 in the working position is used up, the telescopic rod 9 drives the slider 3 to move and complete the position switch. The new roll directly enters the working position without recalibration, realizing roll changing without stopping the laminating machine.

[0034] In overall use, first place both ends of the roll 5 with the film roll 6 into the placement slots 42 of the quick-release component 4 mounting base 41. After rotating the locking block 44, lock it by rotating the T-shaped locking shaft 47. Then slide the limit rings 71 at both ends of the roll 5 to fit the film roll 6. Rotate the rotating cover 714 to drive the extrusion block 711 to fit the roll 5, providing axial force to prevent the film roll 6 from shifting. During lamination, one set of components is in the working position, and the other set is in the film replacement position. After the film roll 6 in the working position is used up, the roll 5 with the new film roll 6 loaded in the film replacement position directly enters the working position. At the same time, the operator loads the new roll at the original working position, realizing continuous production without stopping the machine and improving production efficiency.
