Abstract
Description
Technical Field
[0001] This utility model belongs to the field of printing and laminating technology, specifically referring to a printing and laminating anti-wrinkle device. Background Technology
[0002] Printing lamination is a process of covering the surface of printed materials with a layer of plastic film, mainly used to improve the texture, durability and water resistance of printed materials.
[0003] During printing, the printed material and film are usually moved synchronously by a drive roller, and then the film is pressed firmly onto the printed material by a pressure roller to complete the lamination. However, this method has some drawbacks: during lamination, the printed material or film is easily wrinkled due to tension, and there is a lack of measures to flatten the printed material and film. Therefore, improvements are needed. Utility Model Content
[0004] The technical problem this invention aims to solve is that in the prior art, when laminating printed materials, wrinkles easily appear on the film and the printed materials due to tension, and there is a lack of measures to flatten the printed materials and the film.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a printing and laminating anti-wrinkle device, including a base, a frame fixedly connected to the upper end of the base, slots symmetrically arranged in the frame, a bottom roller rotatably arranged on the frame via a connecting shaft, a pressure roller rotatably arranged above the bottom roller via a connecting shaft, a lifting device arranged in the slot and connected to the pressure roller, a flattening device two arranged on the base to flatten the printed matter, and a flattening device one arranged on the frame to flatten the film.
[0006] Furthermore, the flattening device includes an electric push rod, which is fixed to the top wall of the frame. The output end of the electric push rod is connected to a frame, and a flattening roller is rotatably arranged in the frame. The flattening roller is thick in the middle and thin at both ends.
[0007] Furthermore, the flattening device includes an electric push rod, which is fixed to the bottom of the frame. The output end of the electric push rod is connected to a frame, and a flattening roller is rotatably arranged in the frame. The flattening roller is thick in the middle and thin at both ends.
[0008] Furthermore, the lifting device includes a slider that slides in a slot. An embedded groove is provided on the inner wall of the slot. Limiting blocks are provided at both ends of the slider and slide in the groove. An electric push rod is provided in the slot and connected to the slider. The pressure roller rotates on the slider via a connecting shaft.
[0009] Furthermore, both frame one and frame two are equipped with vibration motors.
[0010] The beneficial effects achieved by adopting the above-described structure are as follows:
[0011] 1. This utility model sets up a flattening device, which pushes the frame through an electric push rod. The flattening roller pushes the film so that the film adheres to the flattening roller. The flattening roller is driven by a vibration motor to vibrate, thereby achieving the flattening effect of the film.
[0012] 2. By setting up a flattening device two, the flattening roller two is attached to the printed matter, which can flatten the printed matter and thus ensure the lamination effect of the printed matter. Attached Figure Description

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0020] like Figure 1-4 This utility model discloses a printing and laminating anti-wrinkle device, including a base 1, a frame 2 fixedly connected to the upper end of the base 1, slots 4 symmetrically arranged in the frame 2, a bottom roller 3 rotatably arranged on the frame 2 via a connecting shaft 5, a pressure roller 6 rotatably arranged above the bottom roller 3 via a connecting shaft 5, a lifting device 7 arranged in the slots 4 and connected to the pressure roller 6, a flattening device 2 8 arranged on the base 1 to flatten the printed matter, and a flattening device 1 9 arranged on the frame 2 to flatten the film.
[0021] like Figure 1-3 The flattening device 9 includes an electric push rod 10, which is fixed to the top wall of the frame 2. The output end of the electric push rod 10 is connected to a frame 11, in which a flattening roller 12 is rotatably mounted. The flattening roller 12 is shaped like a thicker middle section and thinner ends. The electric push rod 10 presses the flattening roller 12 onto the film, flattening it. The principle is that the diameter of the drum-shaped roller is larger in the middle than at both ends. When the roller rotates at a constant angular velocity, the linear velocity of the middle section is greater than that of the ends. When the film is wrapped around the drum-shaped roller, the middle section, due to its higher linear velocity, exerts a pulling force towards the center, while the ends, with their slower linear velocity, experience a stretching force towards both ends. This lateral tension distribution effectively counteracts the wrinkling or curling tendency of the film, "opening" the film and thus achieving flattening, avoiding wrinkles.
[0022] like Figure 1-3 The flattening device 28 includes an electric push rod 214, which is fixed to the bottom of the frame 2. The output end of the electric push rod 214 is connected to a frame 215. Both the frame 11 and the frame 215 are equipped with a vibration motor 22. A flattening roller 217 is rotatably arranged in the frame 215. The flattening roller 217 is thick in the middle and thin at both ends. The electric push rod 214 presses the flattening roller 217 onto the printed matter, and the printed matter is flattened by the flattening roller 217. Its principle is the same as that of the flattening device 19.
[0023] like Figure 1-4The lifting device 7 includes a slider 19, which slides in the slot 4. The inner wall of the slot 4 is provided with an embedded groove 20. Limiting blocks 21 are provided at both ends of the slider 19 and slide in the groove 20. An electric push rod 18 is provided in the slot 4 and connected to the slider 19. The pressure roller 6 rotates on the slider 19 through the connecting shaft 5. By sliding the slider 19, the pressure roller 6 can be lifted and lowered, thereby pressing the film onto the printed material.
[0024] In practical use, when laminating printed materials, the printed materials pass through the bottom roller 3, and the film passes under the pressure roller 6. The electric push rod 3 18 pushes the slider 19 to slide in the slot 4. The limiting block 21 slides in the slide groove 20, which can limit the slider 19 from sliding off course, so that the pressure roller 6 presses the film flat on the printed materials to complete the lamination.
[0025] During the lamination process, by activating the electric push rod 10, the guide rod 13 slides in the frame 2, and at the same time, the flattening roller 12 moves closer to the film until it presses against the film. Similarly, the electric push rod 214 pushes the frame 215, so that the flattening roller 217 adheres to the printed material. Both the flattening roller 12 and the flattening roller 217 are drum-shaped, and in the rotating state, they can flatten the film and the printed material to ensure the quality of lamination.
[0026] Vibration motors 22 are installed on both frame 11 and frame 2 15, which can further vibrate flattening roller 12 and flattening roller 2 17, resulting in a better flattening effect.
[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
