Description

Technical Field

[0001] This utility model relates to the field of printing and laminating machine technology, specifically a digital printing and laminating machine with adjustable roller position. Background Technology

[0002] Digital printing differs from traditional printing in that it allows for printing from a single sheet, variable data, and the dissemination of images and text across various media, significantly expanding the commercial applications of digital imaging. Digital printing is a new printing technology that utilizes a prepress system to directly transmit image and text information via a network to a digital printing press to produce color prints. After printing, many products require surface lamination. A laminating machine is a specialized device for paper and board materials, where rubber rollers and heated rollers press the materials together to form a paper-laminated product, thereby improving the paper's toughness and preventing ink from rubbing off the paper surface.

[0003] The reference patent (Publication No.: CN221161877U; Publication Date: 2024-06-18) relates to the field of printing equipment technology, including a printing body. The printing body has a printing paper feeding groove, and multiple motors are fixed on the inner wall of the printing body. A chain gear is fixed at one end of each motor, and multiple load-bearing rollers are rotatably connected between the motors. It adopts the method of installing an adsorption paper machine to solve the problem of two main types of laminating machines: coating laminating machines and pre-coating laminating machines. It increases the friction of the rollers to make the paper move back and forth in the paper feeding groove, and after multiple ink sprays, lamination is performed. However, in existing laminating machines, the upper and lower roller positions in the paper feeding groove are fixed, and it is impossible to adjust the lamination gap for products of different thicknesses. Or the roller positions can be adjusted, but each time it is used, the main structure of the digital printing laminating machine needs to be disassembled and the roller positions manually adjusted, which makes the process complicated, reduces the user experience, reduces production efficiency, and the accuracy of manual adjustment is not high, affecting the yield.

[0004] The conveyor rollers of digital printing laminators ensure that the paper is transported smoothly and accurately during the printing and lamination process. Then, the hot press rollers are heated by electric heating tubes or heat transfer oil, and in conjunction with the pressure adjustment mechanism, the hot press lamination process is realized. However, the adjustment of the roller and hot press roller positions of traditional laminators is cumbersome and requires manual operation, which is time-consuming and labor-intensive. Since the positions of the rollers and hot press rollers are fixed, they cannot adapt to paper of different specifications and thicknesses, which limits the versatility and flexibility of the equipment. Utility Model Content

This solves the problems of cumbersome roller and hot press roller shaft position adjustment methods in traditional laminating machines, which require manual operation, are time-consuming and labor-intensive, and cannot adapt to different paper specifications and thicknesses due to the fixed positions of the rollers and hot press roller shafts, thus limiting the versatility and flexibility of the equipment.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a digital printing and laminating machine with adjustable roller position, including a printing and laminating machine body, with openings and slots opened on the side walls at both ends of the printing and laminating machine body;

[0007] The printing and laminating machine body is equipped with a feeding mechanism for paper feeding, the feeding mechanism including:

[0008] An adjustment component for adjusting the spacing according to the paper thickness;

[0009] A guide assembly is mounted on the adjustment assembly and has a heat-pressing assembly for the laminating software inside.

[0018] Beneficial effects

[0019] This invention provides a digital printing and laminating machine with adjustable roller position. Compared with the prior art, it has the following advantages:

[0020] Firstly, the push block in this invention is telescopically operated by an electric push rod. A connecting rod is rotatably connected to the push block via a first rotating shaft, and the slider is rotatably connected to the connecting rod via a second rotating shaft. This allows the connecting rod to push the slider, ensuring the slider slides along the interior of the slide rail bracket with adjustable spacing. The conveying rollers then rotate on the slider via a motor, adjusting their position according to the thickness of the paper being conveyed. This adapts to different paper sizes and thicknesses, enhancing the machine's versatility and flexibility, meeting diverse production needs. Furthermore, the telescopic control of the electric push rod enables automated adjustment of the roller position, eliminating the need for manual adjustment and significantly improving production efficiency and ease of operation.

[0021] Secondly, the slider of this utility model is fixedly connected to the connecting block on one side wall inside the main body of the printing and laminating machine, and is fixedly connected to the second connecting bracket. When the slider drives the conveying roller to adjust the spacing, it drives the spacing between the second connecting bracket and the first connecting bracket to be controlled synchronously. The hot pressure roller shaft on the connecting bracket is adjusted according to the thickness of the paper, and the spacing between the hot pressure roller shaft and the paper is controlled to ensure that the pressure and temperature during the hot pressing process can be evenly distributed on the paper, thereby improving the quality and effect of lamination. This allows the laminating machine to handle paper of different specifications and thicknesses, enhances the versatility and flexibility of the machine, and reduces the time for manual intervention and adjustment.

A second rotating shaft 305 is provided on the side wall of the slider 202 extending to the outside of the opening slot 2. The push block 302 is telescopically connected to the electric push rod 301, and then the connecting rod 304 rotates with the push block 302 via the first rotating shaft 303. The sliding block 202 is rotatably connected to the connecting rod 304 via the second rotating shaft 305, allowing the connecting rod 304 to push the sliding block 202. This ensures that the sliding block 202 slides along the interior of the slide rail bracket 201 with adjustable spacing. Then, the conveying roller 203 rotates on the sliding block 202 via a motor, adjusting its position according to the thickness of the paper being conveyed.

Then, the slider 202 is fixedly located on one side wall inside the printing and laminating machine body 1. The fixed connecting block 4 is fixedly connected to the second connecting bracket 402. When the slider 202 drives the conveying roller 203 to adjust the spacing, it synchronously controls the spacing between the second connecting bracket 402 and the first connecting bracket 401. The hot press roller shaft 404 on the connecting bracket is adjusted according to the thickness of the paper. The spacing between the hot press roller shaft 404 and the paper is controlled to ensure that the pressure and temperature during the hot pressing process can be evenly distributed on the paper, thereby improving the quality and effect of lamination.

The bolt 703 is rotated to lock it, ensuring that the opening and closing plate 702 is open. After using the equipment, the bolt 703 is loosened, the opening and closing plate 702 is rotated downwards, and then the bolt 703 is used to lock the opening and closing plate 702. This is used to close the conveying and output housing, which can effectively protect the inside of the equipment from the intrusion of dust, dirt and other debris, and helps to extend the service life of the equipment and maintain the good condition of the equipment.
