Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and more specifically, to an environmentally friendly printing laminating machine. Background Technology

[0002] Lamination is a surface finishing process after printing, also known as post-printing lamination, post-printing gluing, or post-printing film application. It refers to the process of using a laminating machine to cover the surface of printed materials with a transparent plastic film, forming a paper-plastic composite product. It is widely used in the printing industry. However, existing printing laminating machines cannot smooth the edges of the laminated product, resulting in poor flatness of the film edges. This requires manual repair, which is time-consuming and labor-intensive. Furthermore, it is not easy to cut the product into sections. Therefore, a laminating machine is provided. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides an environmentally friendly printing and laminating machine, which aims to solve the problems mentioned in the background art.

[0004] This utility model provides the following technical solution: an environmentally friendly printing and laminating machine, including a support frame, on which a laminating component is provided;

[0005] The film coating assembly includes a connecting seat disposed on the top of the support frame, a film roll disposed on the connecting seat, a feeding plate disposed in the middle of the support frame, and material support plates disposed on both sides of the feeding plate.

[0006] Two tensioning rollers for tensioning the film roll are provided at one end of the feeding plate, and each tensioning roller is threadedly connected to a vertical rod. The top ends of the vertical rods extend to the support frame and are slidably connected to the support frame. A first spring is sleeved on the outer side of each vertical rod.

[0007] Optionally, in one possible implementation, a vertical plate is bolted to the top of the inner cavity of the support frame. Two pulleys are rotatably connected to one side of the bottom of the vertical plate. The two pulleys are connected by a conveyor belt. A motor for driving the pulleys to rotate is provided on the side of the vertical plate away from the pulleys. A slider is bolted to the bottom outer side of the conveyor belt. A cutting blade for cutting is provided at the bottom of the slider. The top of the slider extends to the bottom of the vertical plate and is slidably connected to the vertical plate. Two inclined rods are provided at both ends of the vertical plate. The top of each inclined rod extends to the support frame and is slidably connected to the support frame. A second spring is sleeved on the outer side of the inclined rod, and the top of the second spring abuts against the support frame. A pressure roller is rotatably connected to the bottom end of the inclined rod, and the pressure roller extends to the top of the material support plate.

[0008] The technical effects and advantages of this utility model are as follows:

[0009] By tilting the inclined extension rod and cooperating with the elastic tension of the second spring, the pressure roller can adaptively conform to the laminated product on the support plate, and the pressure can be adjusted according to the thickness of the printed material. The pressure roller rotates synchronously with the product, squeezing and smoothing the edge of the film material, effectively expelling air between the film material and the printed material, avoiding problems such as bubbles and curling edges, and greatly improving edge flatness. No subsequent manual edge repair is required, reducing labor costs and avoiding secondary damage caused by manual operation.

[0010] The vertical rod is slidably connected to the support frame. The elastic force of the first spring always pushes the tension wheel downward to squeeze the film material. Even if the diameter of the film roll gradually decreases during use, the tension wheel can move down synchronously to maintain the stability of the film tension. The tension wheel is made of rubber and has anti-slip texture on its surface, which can not only avoid scratching the film material, but also enhance the friction with the film material, further preventing the film material from slipping and wrinkling, ensuring that the film material and the printed material are evenly bonded during the lamination process, and improving the overall lamination quality.

[0017] 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.

[0018] The environmentally friendly printing and laminating machine disclosed in this embodiment aims to solve the technical pain points of existing laminating machines, such as poor edge smoothness of the laminated product, the need for manual repair, and difficulty in segmented cutting. Its core structure includes a support frame 1 and a laminating component, a smoothing component, and a cutting component integrated on the support frame 1.

[0019] As attached Figure 1 and attached Figure 2 As shown, the support frame 1 is a rectangular frame made of stainless steel. The top of the support frame 1 has a threaded hole for installing the film coating component. A horizontally set feeding plate 7 is welded in the middle. The top of the inner cavity is fixed with a vertical plate 9 for installing the cutting component and the smoothing component. The overall structure has high strength and good stability.

[0020] The laminating assembly is the core component of the equipment, used to stably cover the surface of the printed material with the transparent plastic film of the film roll 3. Its structure includes a connecting seat 2, film roll 3, tension wheel 4, vertical rod 5, first spring 6, feeding plate 7, and material support plate 8, as detailed below:

[0021] As attached Figure 1 As shown, the connecting seat 2 consists of two symmetrically arranged steel plates, which are fixed to the two ends of the top of the support frame 1 by bolts. The two connecting seats 2 are rotatably connected to a metal shaft on opposite sides. The film roll 3 is a PET environmentally friendly film and is sleeved on the outside of the metal shaft. The film roll 3 can rotate freely around the metal shaft to ensure that the film material can be released at a uniform speed during the film coating process.

[0022] As attached Figure 1 As shown, the feeding plate 7 is an acrylic plate with a smooth surface to avoid scratching the printed matter. It is horizontally welded to the middle of the support frame 1. The material support plate 8 consists of two plates of the same material as the feeding plate 7, which are fixed to both sides of the feeding plate 7 by angle bracket bolts. The material support plate 8 is flush with the upper surface of the feeding plate 7, forming a structure of feeding in the middle and supporting on both sides, ensuring that the printed matter remains horizontal during the lamination process.

[0023] As attached Figure 1 As shown, two symmetrical tensioning rollers 4 are provided above one end of the feeding plate 7 near the film roll 3. The tensioning rollers 4 are made of rubber and are connected to the vertical rod 5 by threads.

[0024] The top of the vertical rod 5 passes through the pre-drilled sliding hole at the top of the support frame 1 and extends above the support frame 1; a first spring 6 is sleeved on the outside of the vertical rod 5. The top of the first spring 6 abuts against the support frame 1 and the bottom abuts against the top of the tension wheel 4. Through the elastic tension of the first spring 6, it can be ensured that the membrane material is always kept taut during the lamination process. The first spring 6 pushes the tension wheel 4 down to maintain stable tension and avoid the membrane material wrinkles from affecting the lamination quality.

[0025] The smoothing assembly is used to press and smooth the edges of the coated product. Its structure includes a slanted extension bar 15, a second spring 16, and a pressure roller 17, as detailed below:

[0026] As attached Figure 2 and attached Figure 3 As shown, two inclined rods 15 are symmetrically arranged at each end of the upright plate 9, and their inclination direction is inclined towards the material support plate 8 to ensure that the pressure roller 17 can accurately press the edge of the film-coated product on the material support plate 8.

[0027] The top end of the inclined rod 15 passes through the support frame 1 and extends to the top of the support frame 1; a second spring 16 is sleeved on the outside of the inclined rod 15, and the top end of the second spring 16 abuts against the support frame 1. Through the elastic force of the second spring 16, the inclined rod 15 can always have downward pressure.

[0028] The bottom end of the inclined rod 15 is rotatably connected to the pressure roller 17 via a bearing. The pressure roller 17 is made of silicone, and its outer circular surface contacts the upper surface of the material support plate 8. The contact pressure can be controlled by adjusting the compression of the second spring 16. When the coated product moves with the feed, the pressure roller 17 will rotate synchronously with the product to squeeze and smooth the film material at the edge of the product, avoiding air bubbles or curling between the film material and the printed material, without the need for subsequent manual repair.

[0029] The cutting assembly is used to precisely cut the laminated product into segments according to requirements. Its structure includes a vertical plate 9, a pulley 10, a conveyor belt 11, a slider 12, a cutting blade 13, and a motor 14. Specific details are as follows:

[0030] As attached Figure 2 and attached Figure 4 As shown, the upright plate 9 is a steel plate, which is fixed to the center of the top of the inner cavity of the support frame 1 by bolts. Two pulleys 10 are rotatably connected to one side of its bottom by bearings and are connected by a conveyor belt 11.

[0031] A motor 14 is fixed to the side of the upright plate 9 away from the pulley 10 by a motor bracket. The output shaft of the motor 14 is connected to the central shaft of one of the pulleys 10 through a coupling. By controlling the forward and reverse rotation and speed of the motor 14, the conveyor belt 11 can be driven to reciprocate in the front-back direction.

[0032] A slider 12 is bolted to the bottom outer side of the conveyor belt 11. The top of the slider 12 is embedded in the slide rail reserved at the bottom of the vertical plate 9 and slides with the slide rail to ensure that the slider 12 can only move along the slide rail direction and avoid the cutting blade 13 from deviating during cutting. The bottom of the slider 12 is bolted to the cutting blade 13. The distance between the blade of the cutting blade 13 and the upper surface of the material support plate 8 is adjustable to ensure that the film material and printed materials can be cut without scratching the material support plate 8.

[0033] The specific working principle is as follows: the PET environmentally friendly film roll 3 is placed on the metal shaft of the connecting seat 2, the free end of the film is pulled out and passed under the two tensioning wheels 4, the compression of the first spring 6 is adjusted, and the height of the tensioning wheel 4 can be adjusted by rotating the vertical rod 5 to ensure that the film is taut and wrinkle-free.

[0034] Adjust the contact pressure between the pressure roller 17 and the material support plate 8 according to the thickness of the printed material; set the operating parameters of the motor 14 according to the required length of the product, control the motor speed and rotation angle, and determine the moving distance and cutting frequency of the cutting blade 13.

[0035] The operator places the printed material to be laminated, such as an A3-sized poster, flat on the feeding plate 7 and pushes the printed material toward the support plate 8. When the printed material passes under the tensioning roller 4, the film material will automatically cover the upper surface of the printed material, forming a preliminary lamination structure.

[0036] The laminated printed material continues to move onto the tray 8. When the edge of the product passes under the pressure roller 17, the pressure roller 17 squeezes the edge of the product under the action of the second spring 16, expelling the air between the film and the printed material, while smoothing the curled edge of the film to ensure that the edge is flat.

[0037] When the smoothed product moves under the cutting blade 13, the motor 14 starts according to the preset parameters, drives the pulley 10 to rotate, the conveyor belt 11 drives the slider 12 to move quickly along the slide rail, and the cutting blade 13 moves with the slider 12 to cut the product laterally; after the cutting is completed, the motor 14 reverses and drives the cutting blade 13 to reset, waiting for the next cutting.

[0038] The cut and laminated finished products are fed out from the end of the material tray 8, and the operators can collect the finished products.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
