Description

Technical Field

[0001] This utility model relates to a printing laminating machine, and more particularly to a film feeding structure for a printing laminating machine, belonging to the technical field of printing laminating machines. Background Technology

[0002] Printed materials are prone to surface wear during daily use and storage. Laminating the surface of printed materials can effectively resist these damages. Large processing plants usually use printing laminating machines to laminate printed materials. However, large laminating machines are complex in structure and expensive, especially the film feeding structure, which usually includes many parts. Small processing plants usually use simple laminating machines with manual film feeding. During the lamination process, the film is easily stretched unevenly, which leads to inconsistent lamination effects between different printed materials, or even film damage and lamination failure.

[0003] Therefore, it is urgent to improve the film feeding structure of the printing laminating machine to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a film feeding structure for a printing laminating machine. The automatic feeding of the film is achieved through a tension component, a clamping component, and a telescopic rod. At the same time, the roller and the counterweight ensure that the film is under stable force during laying. When not laying, the film is not under continuous force, which avoids uneven stretching of the film and ensures that the lamination effect between printed materials is consistent, thus avoiding lamination failure caused by lamination damage.

[0005] To achieve the above objectives, the main technical solution adopted by this utility model includes: a housing, two mounting plates, and a placement plate. The two sides of the placement plate are fixedly connected to the inner side of the housing. The bottoms of the two mounting plates are fixedly connected to the housing.

[0009] Preferably, the mounting plate has a second roller on the side near the placement plate. The two ends of the second roller are rotatably connected to the mounting plate. The upper surface of the second roller is flush with the upper surface of the placement plate. Both ends of the guide groove are inclined downwards and are lower than the upper surface of the placement plate.

[0010] Preferably, the clamping plate assembly includes a second telescopic rod, an upper clamping plate, and a lower clamping plate. The lower clamping plate is fixedly connected to the fixed plate, one end of the second telescopic rod is fixedly connected to the fixed plate, and the other end of the second telescopic rod is fixedly connected to the upper clamping plate.

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-6As shown, the film feeding structure of the printing laminating machine provided in this embodiment includes a housing 1, two mounting plates 2, and a placement plate 3. The two sides of the placement plate 3 are fixedly connected to the inner side of the housing 1. The bottoms of the two mounting plates 2 are fixedly connected to the housing 1. A feeding shaft 4 is fixedly installed between the two mounting plates 2. A film roll 5 is sleeved on the feeding shaft 4. Guide grooves 6 are opened on both sides inside the housing 1. Fixed plates 7 are slidably connected in the guide grooves 6. A clamping plate assembly 8 is provided between the fixed plates 7. A first telescopic rod 10 is connected to the outer side of the mounting plate 2. The other end of the first telescopic rod 10 is connected to the fixed plate 7. A clamping plate assembly 8 is provided between the two mounting plates 2. There is a tension assembly 9. A drive motor 11 for driving the feed shaft 4 is fixedly installed on the outer side of the mounting plate 2. The tension assembly 9 includes a roller 901, a counterweight 902, and a sensor 903. The two ends of the roller 901 are slidably connected to the mounting plate 2. The counterweight 902 is sleeved on both ends of the roller 901. The sensor 903 is fixed on the inner surface of the housing 1. The upper surface of the counterweight 902 is provided with a counterweight adjustment column 12. Multiple counterweight rings 13 are sleeved on the surface of the counterweight adjustment column 12. The sensor 903 is an electromagnetic sensor. A sensing plate 14 is fixedly connected to the outer side of the counterweight 902. The film of the film roll 5 is clamped by the clamping assembly. The film passes under the roller 901 of the tension assembly 9, driven by the first telescopic rod 10. As the clamping assembly moves forward, it moves the film forward, causing the roller 901 to move upward. The film always bears the weight of the counterweight 902 and the roller 901, ensuring stability during application. The counterweight can be adjusted by changing the number of counterweight rings 13, allowing for different weight adjustments for different films. After lamination, the material is removed, and the first telescopic rod 10 retracts, driving the clamping assembly backward to re-clamp the film. At this point, the drive... Motor 11 starts to release the film from film roll 5. When the film is released, roller 901 moves downward. After the sensing plate 14 on the outside of counterweight 902 contacts sensor 903, the motor stops. At this time, telescopic rod 10 moves to the bottom of the chute. Automatic film feeding is achieved through tension component 9, clamping component and telescopic rod 10. At the same time, roller 901 and counterweight 902 make the film stable under force when it is laid. At the same time, when it is not laid, the film is not continuously stressed, avoiding uneven stretching of the film, so that the lamination effect between printed materials is consistent and lamination failure caused by film damage is avoided.

[0024] Among them, such as Figure 1 as well as Figure 2As shown, a roller 15 is provided on the side of the mounting plate 2 near the placement plate 3. The two ends of the roller 15 are rotatably connected to the mounting plate 2. The upper surface of the roller 15 is flush with the upper surface of the placement plate 3. Both ends of the guide groove 6 are inclined downwards and are lower than the upper surface of the placement plate 3. The film of the film roll 5 passes under the roller 901 and is inserted into the clamping plate assembly 8 through the roller 15. When the first telescopic rod 10 extends, it drives the clamping plate assembly 8 to slide along the guide groove 6. The clamping plate assembly 8 drives the film to move upwards first. After the clamping plate assembly 8 passes the placement plate 3, it moves downwards along the guide groove 6 so that the film covers the placement plate 3. The roller 15 reduces the resistance when the film moves.

[0025] Among them, such as Figure 1 as well as Figure 3 As shown, the clamping assembly 8 includes a second telescopic rod 801, an upper clamping plate 802, and a lower clamping plate 803. The lower clamping plate 803 is fixedly connected to the fixed plate 7. One end of the second telescopic rod 801 is fixedly connected to the fixed plate 7, and the other end of the second telescopic rod 801 is fixedly connected to the upper clamping plate 802. When the second telescopic rod 801 extends, it causes the upper clamping plate 802 to move downward. The film is located between the upper clamping plate 802 and the lower clamping plate 803. When the second telescopic rod 801 extends, the upper clamping plate 802 and the lower clamping plate 803 clamp the film. The upper surface of the lower clamping plate 803 is rotatably connected. There is a third roller 16, which is embedded in the lower clamping plate 803. The upper surface of the third roller 16 is higher than the upper surface of the lower clamping plate 803. When the first telescopic rod 10 is shortened, the clamping plate assembly 8 moves backward. At this time, the second telescopic rod 801 of the clamping plate assembly 8 is in a shortened state. The clamping plate assembly 8 does not clamp the film. Then, one end of the waste film is fixed by other mechanisms (waste recycling mechanism). The third roller 16 contacts the waste film when the clamping plate assembly 8 retracts. The third roller 16 reduces the friction between the clamping plate assembly 8 and the waste film.
