Description

Technical Field

[0001] This utility model relates to the field of label production technology, specifically to a backing paper label laminating machine. Background Technology

[0002] Backing-free labels, also known as self-adhesive labels without a backing paper, are a new type of low-carbon and environmentally friendly label. Compared to traditional self-adhesive labels, backing-free labels eliminate the backing paper, retaining only the face material and adhesive. Traditional self-adhesive labels consist of three parts: the surface substrate, the adhesive, and the backing paper. Backing-free labels, however, remove the backing paper, applying the adhesive directly to the face material, and using a special process to separate and adhere the label when needed.

[0003] When laminating backless labels with various materials (such as film, paper, etc.), it may be necessary to laminate multiple layers of different materials. Traditional backless label laminating machines cannot laminate multiple layers of materials with backless labels at the same time. To improve lamination efficiency and the practicality of the device, we propose a backless label laminating machine. Utility Model Content

[0031] 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.

[0032] Please see Figure 1-9 This utility model provides a technical solution: a backing paper label laminating machine, including a shell 1, inside which a plurality of unwinding mechanisms 2, a plurality of tensioning mechanisms 3, a plurality of first laminating mechanisms 4, a plurality of second laminating mechanisms 5, and a winding mechanism 6 are fixedly installed from left to right; inside the shell 1, a glue coating mechanism 38 is fixedly installed; on the right side of the shell 1, a plurality of dryers 37 are fixedly installed; inside the shell 1, a plurality of limiting rollers 21 and a plurality of anti-deviation rollers 16 are rotatably installed; inside the shell 1, a composite material 42 is placed; and the shell 1 has a plurality of mounting holes and a plurality of mating grooves.

[0033] In use, the bonding pressure of the second bonding mechanism 5 is first adjusted according to the thickness and properties of the material to be bonded. Then, the tensioning mechanism 3 slowly pulls the material out from the unwinding mechanism 2 while providing tension. The material then moves forward under the drive of the winding mechanism 6. After reaching the first bonding mechanism 4, the material is bonded for the first time. Under the pull of the winding mechanism 6, the material reaches the second bonding mechanism 5, where the material is bonded for the second time. After drying by the dryer 37, the bonding mechanism 6 finally winds up the bonded material for subsequent use. The limiting roller 21 can limit the position of the material, facilitating processing operations, while the anti-deviation roller 16 can prevent the material from shifting left or right, reducing the failure rate and improving the stability of the device.

[0034] The unwinding mechanism 2 includes an unwinding roller 7, which is rotatably mounted inside the housing 1. A limiting arm 15 is rotatably mounted inside the housing 1. The bottom end of the limiting arm 15 is in close contact with the unwinding roller 7, and a spring is fixedly mounted above the limiting arm 15. The other end of the spring is fixedly mounted on a fixed wall inside the housing 1. The limiting arm 15 can restrict the material inside the unwinding roller 7, preventing the material from scattering outside the unwinding roller 7 when it is pulled, thus preventing malfunctions.

[0035] The tensioning mechanism 3 includes a tensioning motor 8, which is fixedly mounted on the outer casing 1. A first drive pulley 9 is tensioned and sleeved at both ends of the output shaft of the tensioning motor 8. Several first upper pressure rollers 12 are rotatably mounted on the outer casing 1. First driven pulleys 10 are fixedly sleeved at both ends of the left-side first upper pressure roller 12. A belt is tensioned and sleeved between the first drive pulley 9 and the first driven pulley 10. The tensioning mechanism 3 also includes a protective cover 39, which is fixedly mounted inside the outer casing 1. Several first pressure rods 11 are slidably mounted on the outer casing 1. A first lower pressure roller 13 is rotatably sleeved on each first pressure rod 11. First spring frames 14 are fixedly connected to both ends of each first pressure rod 11, and the other end of each first spring frame 14 is fixedly connected to the outer casing 1.

[0036] During operation, the output shaft of the tensioning motor 8 drives the first driving pulley 9 to rotate. Under the action of the belt, the first driven pulley 10 also starts to rotate. Then, the first upper pressure roller 12 on the left side starts to rotate, thereby driving the material forward. The first lower pressure roller 13, under the action of the first spring frame 14, squeezes the material against the first upper pressure roller 12, thereby pulling the material into the tensioning mechanism 3 and providing tension force to the material. The protective cover 39 can prevent the material entering the tensioning mechanism 3 from getting stuck in the components inside the device.

[0037] The first composite mechanism 4 includes a first composite rod 18, which is slidably mounted on the outer casing 1. A first upper composite roller 19 is rotatably mounted on the first composite rod 18. Second spring frames 20 are fixedly mounted at both ends of the first composite rod 18, and the other end of the second spring frames 20 is fixedly connected to the outer casing 1. A first lower composite roller 17 is rotatably mounted inside the outer casing 1. Under the action of the second spring frames 20, the first lower composite roller 17 squeezes the material towards the first upper composite roller 19, enhancing the composite effect.

[0038] The second composite mechanism 5 includes a second composite rod 26, which is slidably mounted on the outer casing 1. A second upper composite roller 27 is rotatably mounted on the second composite rod 26. Third spring frames 40 are fixedly mounted at both ends of the second composite rod 26. A threaded plate 28 is fixedly connected to the outer casing 1, and a nut 29 is threaded onto the threaded plate 28. The bottom end of the nut 29 is in close contact with the upper end of the third spring frame 40. A second lower composite roller 25 is rotatably mounted inside the outer casing 1. In use, the elasticity of the third spring frame 40 is adjusted according to the thickness and properties of the composite material. The elasticity is adjusted by rotating the nut 29 to press the third spring frame 40 downwards. Under the action of the third spring frame 40, the second lower composite roller 17 presses the material against the second upper composite roller 27, which not only enhances the composite effect but also improves the practicality of the device.

[0039] The winding mechanism 6 includes a winding roller 30, which is rotatably mounted on the outer casing 1. The front and rear ends of the winding roller 30 are fixedly fitted with second driven pulleys 32. A winding motor 31 is fixedly mounted on the outer casing 1. The output shaft of the winding motor 31 is fixedly fitted with second driving pulleys 33 at both ends. A belt is tensioned between the second driving pulleys 33 and the second driven pulleys 32. A second pressing rod 35 is slidably mounted on the outer casing 1. A second upper pressing roller 36 is rotatably mounted on the second pressing rod 35. A fourth spring frame 41 is fixedly mounted at both ends of the second pressing rod 35. The other end of the fourth spring frame 41 is fixedly connected to the outer casing 1. A second lower pressing roller 34 is rotatably mounted inside the outer casing 1. In use, the output shaft of the winding motor 31 drives the second drive pulley 33 to rotate. Under the action of the belt, the second driven pulley 32 also starts to rotate. Then the winding roller 30 starts to rotate, thereby driving the entire material to move forward. Under the action of the fourth spring frame 42, the second upper pressure roller 36 squeezes the material against the second lower pressure roller 34, providing tension to the material and improving the winding effect.

[0040] The glue application mechanism 38 includes a glue storage tank 22, which is fixedly installed on the outer shell 1. The glue storage tank 22 is fixedly connected to a glue application pipe 23, and the glue application pipe 23 is fixedly connected to a plurality of glue application nozzles 24.

[0041] Several springs are installed inside the first spring frame 14, the second spring frame 20, the third spring frame 40, and the fourth spring frame 41.

[0042] Several heat sinks are fixedly installed on the outer surface of the winding motor 31, which can improve the heat dissipation performance of the winding motor 31.

[0043] Working principle: In use, the composite pressure of the second composite mechanism 5 is first adjusted according to the thickness and properties of the material to be composited. This function is achieved by rotating the nut 29 to compress the third spring frame 40. Then, the tensioning motor 8 is turned on, and the output shaft of the tensioning motor 8 drives the first driving pulley 9 to rotate. Under the action of the belt, the first driven pulley 10 also starts to rotate. Then, the first upper pressure roller 12 on the left side starts to rotate, thereby pulling the material from the unwinding mechanism 2 into the interior of the tensioning mechanism 3. The first lower pressure roller 13, under the action of the first spring frame 14, squeezes the material against the first upper pressure roller 12 to provide tension for the material. The protective cover 39 can prevent the material entering the tensioning mechanism 3 from getting stuck in the components inside the device.

[0044] Then, the take-up motor 31 is turned on. The output shaft of the take-up motor 31 drives the second drive pulley 33 to rotate. Under the action of the belt, the second driven pulley 32 also starts to rotate. Then the take-up roller 30 starts to rotate, thereby driving the entire material to move forward. Under the action of the fourth spring frame 42, the second upper pressure roller 36 squeezes the material against the second lower pressure roller 34, providing tension to the material and improving the winding effect.

[0045] Driven by the winding motor 31, the material moves forward to the first composite mechanism 4, where it begins to be composited for the first time. The first lower composite roller 17, under the action of the second spring frame 20, squeezes the material against the first upper composite roller 19, enhancing the composite effect. Then, the material moves to the second composite mechanism 5, where it begins to be composited for the second time. After drying by the dryer 37, the composited material is finally wound up by the winding mechanism 6 for subsequent use.
