Description

Technical Field

[0001] The invention relates to the technical field of laminating equipment, and in particular to an anti-wrinkle laminating machine for producing food labels and a use method thereof. Background Art

[0002] Food labels refer to the words, graphics, symbols, and all explanatory materials on pre-packaged food containers. Pre-packaged food refers to food that is pre-packaged in a container for delivery to consumers. All content on a food label must not describe or introduce the food in a wrong, misleading, or deceptive manner, nor may it cause consumers to confuse a food or a certain property of a food with another product through direct or indirect suggestive language, graphics, or symbols. When producing food labels, it is necessary to laminate the surface of the label. Laminating refers to a product processing technology that covers the surface of a product with a layer of transparent plastic film to form a paper-plastic integrated product. The surface of the product is laminated to achieve the purpose of dustproofing and waterproofing the product surface. A laminating machine is a special equipment for laminating paper, plates, etc.

[0003] At present, when traditional food labels are produced and laminated, the lamination will wrinkle and curl, which affects the appearance after lamination.

[0025] 1. The anti-wrinkle laminating machine for producing food labels and the method of using the anti-wrinkle laminating machine utilizes the extended end of the cylinder to extend and, through the connection of the crossbeam, drives the frame to move downward, and drives the push plate and the bar teeth to move downward, and the film is pressed by the push plate and the bar teeth to fit with the label tape, and the film and the label tape are rolled up by external equipment, so that the arc surface at the bottom of the bar teeth contacts the film, thereby flattening the film, and utilizing the arc-shaped push plate to make the bottom of the push plate contact the film again, so that the film is subjected to pressure and is not prone to wrinkles.

[0026] 2. The anti-wrinkle laminating machine and use method for producing food labels: as the cross beam moves downward, the rolling assembly as a whole is driven to move downward, and under the support and connection of the connecting square rod, the pressing roller is used to contact the film.

10. A method for using an anti-wrinkle laminating machine for producing food labels, characterized in that: The following steps are involved: Step 1: Pass one end of the label tape on the label tape unwinding roller (3) through the bottom of the round roller (66) and the bottom of the wiping member (73), and through the bottom of the push plate (55) and the bottom of the pressing roller (562), and pass one end of the film on the film unwinding roller (2) through the bottom of the push plate (55) and the bottom of the pressing roller (562), so that the film is above the label tape; Step 2: The cylinder (52) is turned on to work, and the extended end of the cylinder (52) is extended to push the frame (54) downward, so that the push plate (55) and the strip teeth (57) can be driven to move downward, and the film is pressed by the push plate (55) and the strip teeth (57) to fit the label tape, and the film and the label tape are rolled up by an external device, so that the arc surface at the bottom of the strip teeth (57) contacts the film, so that the film is flattened, and the push plate (55) is arc-shaped, so that the bottom of the push plate (55) contacts the film again, so that the film is subjected to pressure; Step 3: The nip roller (562) contacts the film, and as the cross beam (53) continues to move downward, the connecting square rod (561) is pressed to expand to both sides, and the pressing elastic strip (563) is squeezed to elastically deform, and the connecting square rod (561) is subjected to the downward elastic pressing force of the pressing elastic strip (563) by combining the action force and the reaction force, so that the film is rolled and pressed by the rolling of the nip roller (562); Step 4: As the conical cap (58) moves downward, it is pressed downward, the guide rod (62) moves downward, the spring (65) is stretched, and under the connection of the strip hole (63), the right-angle rod (64) is pressed and rotated to adjust the angle, and the push roller (68) is lifted by the connection of the swing link (67). Through the interaction between the push roller (68) and the round roller (66), the label belt is tensioned; Step 5: Loosen the screws on the outer cylindrical surfaces of the sliding sleeves at both ends of the support strip beam (72), and adjust the height of the support strip beam (72) so that the bottom of the wiping member (73) is fully in contact with the label tape, and use the push roller (68) to move upward so that the push roller (68) is located between the round roller (66) and the support strip beam (72), so that the label tape is not easily disordered; Step 6: The film is fitted with the wiping piece (73), and under the elastic force provided by the elastic ring (74), the bottom of the wiping piece (73) is in elastic contact with the label tape, which is not easy to cause damage to the label tape. At the same time, as the label tape moves toward the side close to the pressing roller (562), the dust and debris attached to the surface of the label tape can be wiped off.
