Description

Technical Field

[0001] This utility model relates to the field of lamination and pressing technology, specifically a pressing mechanism for a lamination device for raw paper in gift bag production. Background Technology

[0002] A laminating machine is a specialized printing equipment used for paper, board, and film lamination. It is an important product for achieving paper-plastic integration. After the paper and plastic parts are pressed together by the heating roller and pressing roller of the laminating machine, the paper and plastic film are bonded together.

[0003] A search revealed a patent numbered CN209478949U, which describes a flat, glossy paper-plastic pressing device for a laminating machine. This device facilitates the transport of paper and plastic parts within the machine casing by opening an inlet and outlet connected by guide rail grooves. A pressure roller is elastically installed at the upper end of the casing, using spring force and the weight of the suspension rod and the pressure roller itself to elastically press the paper and plastic together. A connecting rod with symmetrical pins ensures the stability of the suspension rod and pressure roller's vertical movement, guaranteeing a uniform and balanced force application and distribution on the pressure roller.

[0004] However, the existing upper and lower pressure rollers generally adopt a fixed installation structure, which can only squeeze paper and plastic parts of a certain thickness, and wrinkles will appear during the film pressing process of the upper and lower pressure rollers. However, the above-mentioned patent does not solve the problem of ironing the wrinkles in the pressure roller pressing, thereby improving the quality of paper production.

[0005] Therefore, we need a pressing mechanism for the paper lamination device in gift bag production, which solves the existing pressing problem of paper lamination in gift bag production and can also realize the pressing, wrinkling and ironing of paper lamination in gift bag production.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pressing mechanism for a paper laminating device for gift bag production, comprising a housing, a hydraulic cylinder fixedly connected to the inner surface of the housing, a lifting frame and a fixed frame fixedly connected to the output shaft end of the hydraulic cylinder, an upper hot press roller and a lower hot press roller rotatably connected between the two side plates of the lifting frame and the fixed frame, a movable frame provided on the side surface of the lifting frame, an ironing plate provided at the bottom of the movable frame, and an electric heating plate provided at the top of the ironing plate.

[0008] Preferably, the cross-sections of the lifting frame and the fixed frame body are arranged in a "C" shape, and the width dimensions of the lifting frame and the fixed frame body are the same.

[0009] Preferably, the radius dimensions of the upper hot pressing roller and the lower hot pressing roller are the same, and the center points of the upper hot pressing roller and the lower hot pressing roller are arranged on the same hammer surface.

[0010] Preferably, a guide groove is formed on the surface of the lifting frame, and an installation block is movably connected to the surface of the guide groove. The surface of the installation block is movably connected to the surface of a guide rod, and the end of the guide rod is fixedly connected to the surface of the guide groove. A spring is sleeved on the surface of the guide rod. The end of the installation block is fixedly connected to the end face of a moving frame. The inclined surface of the moving frame faces downward, and the cross-section of the moving frame is arranged in a "C" shape.

[0011] Preferably, the surface of the guide groove is closely attached to the surface of the installation block. The cross-section of the installation block is arranged in a "convex" shape. There are two groups of installation blocks, and the two groups of installation blocks are symmetrically arranged along the center point of the lifting frame.

[0012] Preferably, a fixing rod is fixedly connected between the two side plates of the moving frame. The surface of the fixing rod is rotatably connected to the inside of a hinge block. The bottom surface of the hinge block is fixedly connected to the top surface of an ironing board. There are two groups of hinge blocks, and the two groups of hinge blocks are symmetrically arranged along the central axis of the ironing board.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: By starting the hydraulic cylinder, the lifting frame can be adjusted in position inside the machine case. The raw material paper can be subjected to film covering and compression by the upper hot pressing roller and the lower hot pressing roller. By turning on the electric heating plate, the ironing board can be heated. Therefore, the ironing board can iron the wrinkles that appear on the raw material paper covered and pressed by the upper hot pressing roller and the lower hot pressing roller. When the paper is being wound up, the upper hot pressing roller and the lower hot pressing roller perform film covering and pressing on it. Due to the elastic force of the spring, the moving frame can adjust its position so that the ironing board can perform ironing and pressing on the paper. By rotatably connecting the inside of the hinge block to the surface of the fixing rod and fixedly connecting the bottom surface of the hinge block to the top surface of the ironing board, when the lifting frame moves downward, the bottom surface of the ironing board can perform pressing and ironing on the covered paper raw material, thereby preventing wrinkles from appearing after the paper raw material is covered with a film; further solving the problem of film covering and pressing of the existing raw material paper for producing gift bags, and also realizing the film covering and pressing and wrinkle ironing of the raw material paper for producing gift bags.

[0022] Please see Figures 1-5 This utility model provides a pressing mechanism for a coating device for raw material paper in gift bag production. It includes a housing 1, with a hydraulic cylinder 2 fixedly connected to the inner surface of the housing 1. A lifting frame 3 and a fixed frame 6 are fixedly connected to the output shaft end of the hydraulic cylinder 2. An upper hot press roller 4 and a lower hot press roller 5 are rotatably connected between the two side plates of the lifting frame 3 and the fixed frame 6. A movable frame 7 is provided on the side surface of the lifting frame 3, and an ironing plate 11 is provided at the bottom of the movable frame 7. An electric heating plate 10 is provided at the top of the ironing plate 11. By activating the hydraulic cylinder 2, the lifting frame 3 can be adjusted within the housing 1. By rotatably connecting the upper hot press roller 4 and the lower hot press roller 5 within the lifting frame 3 and the fixed frame 6, the raw material paper can be coated and compressed using the upper and lower hot press rollers 4 and 5. By opening the electric heating plate 10, the ironing plate 11 can be heated, thus ironing the wrinkles appearing on the coated raw material paper pressed by the upper and lower hot press rollers 4 and 5.

[0023] In order to adjust the position so that the ironing board 11 can iron and press the paper, a guide groove 12 is provided on the surface of the lifting frame 3. A mounting block 14 is movably connected to the surface of the guide groove 12. The surface of a guide rod 13 is movably connected inside the mounting block 14. The end of the guide rod 13 is fixedly connected to the surface of the guide groove 12. A spring 15 is sleeved on the surface of the guide rod 13. The end of the mounting block 14 is fixedly connected to the end face of the moving frame 7. The inclined surface of the moving frame 7 faces downward, and the cross section of the moving frame 7 is arranged in a "C" shape.

[0024] By movably connecting the surface of the guide rod 13 inside the mounting block 14 and then fixedly connecting the surface of the mounting block 14 to the end face of the moving frame 7, the position of the moving frame 7 can be adjusted on the surface of the lifting frame 3 by the elastic force of the spring 15. When the upper hot pressing roller 4 and the lower hot pressing roller 5 perform film laminating and pressing on the paper during the winding process, the elastic force of the spring 15 enables the moving frame 7 to adjust its position so that the ironing board 11 can iron and press the paper. <{

[0025] To prevent wrinkles from appearing on the paper raw material after film lamination, a fixing rod 8 is fixedly connected between the two side plates of the moving frame 7. The surface of the fixing rod 8 is rotatably connected inside a hinge block 9. The bottom surface of the hinge block 9 is fixedly connected to the top surface of the ironing board 11. The hinge blocks 9 are provided in two groups, and the two groups of hinge blocks 9 are symmetrically arranged about the center axis of the ironing board 11.

[0026] By rotatably connecting the surface of the fixing rod 8 inside the hinge block 9 and fixedly connecting the bottom surface of the hinge block 9 to the top surface of the ironing board 11, the downward movement of the lifting frame 3 enables the bottom surface of the ironing board 11 to press and iron the paper raw material after film lamination, thereby preventing wrinkles from appearing on the paper raw material after film lamination.

[0027] In actual use, the lifting frame 3 is adjustable inside the machine housing 1 by activating the hydraulic cylinder 2. The upper and lower hot press rollers 4 and 5 are rotatably connected to the lifting frame 3 and the fixed frame 6, thus the raw material paper can be laminated and compressed by the upper and lower hot press rollers 4 and 5. The ironing plate 11 is heated by turning on the electric heating plate 10, thus ironing the wrinkles of the raw material paper laminated by the upper and lower hot press rollers 4 and 5. The surface of the guide rod 13 is movably connected inside the mounting block 14, and then the surface of the mounting block 14 is fixedly connected to the moving frame. The end face of 7, therefore, the position of the moving frame 7 can be adjusted on the surface of the lifting frame 3 by the elastic force of the spring 15. When the paper is rolled up, the upper hot pressure roller 4 and the lower hot pressure roller 5 apply a film to it. The position of the moving frame 7 can be adjusted by the elastic force of the spring 15 so that the ironing plate 11 irons and presses the paper. By rotating the internal surface of the hinge block 9 to connect the fixed rod 8, the bottom surface of the hinge block 9 is fixedly connected to the top surface of the ironing plate 11. Therefore, the downward movement of the lifting frame 3 allows the bottom surface of the ironing plate 11 to press and iron the paper material after film application, thereby preventing wrinkles from appearing on the paper material after film application.
