Description

Technical Field

[0001] The invention relates to the technical field of laser card paper production, in particular to a gluing device and a gluing method for an environmentally friendly laser card paper. Background Art

[0002] Environmentally friendly water-based laser cardboard is widely used for cigarette hard packs, alcohol, medicine, cosmetics, food and other product packaging boxes. Existing environmentally friendly water-based laser cardboard is usually an integrated structure. In order to appropriately increase its strength, the bottom of the environmentally friendly water-based laser cardboard can be reinforced by gluing. It can be seen that the connection between the environmentally friendly water-based laser cardboard and the reinforcement layer requires a transition process of gluing.

[0003] The existing patent announcement number is CN220697254U, which is an environmentally friendly water-based laser cardboard gluing device, aiming to solve the current technical problem of inconvenient cleaning and recycling of excess glue on the surface of laser cardboard. It includes a scraper, and a guide groove is opened through the upper surface of the scraper, and the guide groove is V-shaped. A scraping groove is opened at the lower end of the inner wall of the guide groove, and a collecting port is opened below the inner wall of the scraping groove. A glue feed groove is opened inside the scraper, and the glue feed groove is V-shaped.

[0004] The above existing patents and traditional gluing devices have the following problems:

[0005] The existing gluing device uses a scraper to evenly scrape the glue on the surface of the laser cardboard during gluing. However, the existing device drives the scraper to move back and forth. When scraping the glue, the accumulated glue will be evenly scraped along the moving path of the scraper and then the excess glue will be scraped off, while the position without glue cannot be scraped with glue. The glue in the forward and backward moving direction of the scraper will be repeatedly smeared, so that the glue on the laser cardboard will be unevenly smeared. In addition, the laser cardboard cannot be quickly replaced before and after gluing, and manual pushing and other operations are required, resulting in low gluing efficiency.

DETAILED DESCRIPTION

[0033] In order to further explain the technical solution of the present invention, it is described in detail below through specific embodiments.

[0034] Please refer to Figures 1 to 3. The present invention provides an environmentally friendly laser paper gluing device and a gluing method thereof, comprising a gluing platform 1, a supporting base frame 2, a gluing lower plate 3, a gluing upper plate 4, a glue injection pipe 5, a glue outlet 6, a smoothing device 7 and a circulating pushing mechanism 8. The supporting base frame 2 is installed at the bottom of the gluing platform 1, and the gluing lower plate 3 is slidably connected to the gluing platform 1. The upper part of the gluing lower plate 3 is provided with a gluing upper plate 4, and one end of one side of the gluing upper plate 4 is respectively provided with a glue injection pipe 5, and the glue injection pipe 5 extends to the inside of the gluing upper plate 4 and is connected with two glue outlets 6 arranged on the bottom surface of the gluing upper plate 4; the gluing upper plate 4 is connected with a smoothing device 7, and the smoothing device 7 is installed on both ends of the gluing platform 1, and the bottom of the gluing platform 1 is provided with a circulating pushing mechanism 8, and the circulating pushing mechanism 8 is installed on the horizontal plate in the middle of the supporting base frame 2, and the upper end of the circulating pushing mechanism 8 is connected to the gluing lower plate 3.

[0035] Among them, protruding plates are provided on both sides of the gluing lower plate 3 and are slidably connected with the grooves on both sides of the gluing platform 1, so that the gluing lower plate 3 can move back and forth on the gluing platform 1 driven by the circulating pushing mechanism 8.

[0036] Specifically, before gluing, the circulating pushing mechanism 8 pushes the gluing lower plate 3 out of the bottom of the smoothing device 7 after working, then takes out the glued laser cardboard, puts in the laser cardboard to be glued, and then the circulating pushing mechanism 8 continues to work to push the gluing lower plate 3 back into the bottom of the smoothing device 7, and then connects the external glue injection equipment through the external interface of the glue injection tube 5, injects glue into the glue injection tube 5, and then discharges it from the two glue discharge ports 6 at the bottom of the gluing upper plate 4 to the laser cardboard placed on the gluing lower plate 3, and then the smoothing device 7 performs the smoothing work.

[0037] Please refer to Figures 2 and 3. The smoothing device 7 of the present invention includes a circular pushing mechanism 71, a supporting column 72, a fixed top plate 73 and a first motor 74. The circular pushing mechanism 71 is installed on the gluing platform 1 through the supporting column 72, the fixed top plate 73 is arranged on the top of the circular pushing mechanism 71 and is connected to the supporting column 72, and the first motor 74 is installed on one side of the fixed top plate 73.

[0038] Among them, four supporting columns 72 are provided, which are respectively connected to the four corners of the supporting frame 711, and the top is connected to the four corners of the fixed top plate 73, which can provide stable support.

[0039] Specifically, the four corners of the fixed top plate 73 are supported on the gluing platform 1 by four supporting columns 72. After the first motor 74 installed on one side of the fixed top plate 73 works, it drives the circular pushing mechanism 71 to work, and then the circular pushing mechanism 71 drives the gluing upper plate 4 to move in a circular shape, and the gluing upper plate 4 performs the smoothing work.

[0040] Please refer to Figures 3 to 6. The circular push mechanism 71 of the present invention includes a support frame 711, a first slide rail 712, a slideway 713, a movable plate 714, a second slide rail 715, a connecting frame 716, a sliding sleeve 717, a sliding column 718, a connecting rod 719, a center block 7110, a center column 7111, a first pulley 7112, a belt 7113 and a second pulley 7114. The corners of the support frame 711 are connected to the support column 72, and the first slide rail 712 is horizontally provided at the bottom of the support frame, and the slideway 713 is provided at the upper end. The bottom of the support frame 711 is provided with a movable plate 714, and the upper end of the movable plate 714 is slidably connected to the first slide rail 712 by a horizontal groove, and the bottom of the movable plate 714 is longitudinally provided with a second The slide rail 715 and the upper glue plate 4 are arranged at the bottom of the movable plate 714, and the longitudinal groove at the upper end of the upper glue plate 4 is slidably connected to the second slide rail 715. The upper glue plate 4 is connected with connecting frames 716 on both sides, and the middle part of the connecting frame 716 is rotatably connected to the sliding sleeve 717. The sliding sleeve 717 is slidably connected to the connecting rod 719 on one side of the center block 7110. The bottom of the center block 7110 is rotatably connected to the middle part of the support frame 711 through the center column 7111. Both sides of the center block 7110 are connected to the inner side of the first pulley 7112 through the connecting rod 719. The outer side of the first pulley 7112 is connected to the second pulley 7114 through the belt 7113. The middle part of the second pulley 7114 is connected to the output end of the first motor 74.

[0041] The slideway 713 is configured to be circular, so that the sliding column 718 can make a circular motion in the slideway 713, thereby driving the gluing upper plate 4 to move in a circular motion.

[0042] Specifically, after the first motor 74 works, it drives the second pulley 7114 to rotate, and through the transmission of the belt 7113, drives the first pulley 7112 to rotate synchronously. After the first pulley 7112 rotates, it drives the two groups of connecting rods 719 on the inner side to rotate around the central block 7110 as the center, and the bottom of the central block 7110 is rotatably connected to the support frame 711 through the central column 7111, and then the sliding sleeve 717 slides on the connecting rod 719 on one side of the central block 7110, and at the same time, the sliding column 718 at the bottom of the sliding sleeve 717 moves in the circular slideway 713, thereby driving the connecting frame 716 to rotate. The connecting frame 716 then drives the bottom gluing upper plate 4 to move in a circular shape, and the slide groove at the upper end of the gluing upper plate 4 is slidably connected to the second slide rail 715, and the slide groove at the upper end of the moving plate 714 is slidably connected to the first slide rail 712. Therefore, when the sliding column 718 moves in a circular shape in the circular slideway 713, the moving plate 714 will move horizontally and the gluing upper plate 4 will move vertically. After the gluing upper plate 4 moves horizontally under the horizontal movement of the moving plate 714, it moves vertically, then moves horizontally, and finally moves vertically again to realize the circular movement and evenly spread the laser cardboard on the gluing upper plate 3.

[0043] Please refer to Figures 7 to 9. The circulating pushing mechanism 8 of the present invention includes a first slide groove 81, a second slide groove 82, a second motor 83, a rotating arm 84, a rotating shaft 85, a swing arm 86, a connecting piece 87 and a slide plate 88. The first slide groove 81 is horizontally provided on the gluing platform 1, and the second slide groove 82 is longitudinally provided in the middle of both sides. The second motor 83 is installed on the horizontal plate in the middle of the supporting base frame 2, and the upper output end of the second motor 83 is connected to one end of the rotating arm 84, and the other end of the rotating arm 84 is rotatably connected to the middle of the swing arm 86 through the rotating shaft 85. Connecting pieces 87 and slide plates 88 are respectively provided at both ends of the swing arm 86, and the connecting piece 87 and slide plates 88 slide on the inner sides of the first slide groove 81 and the second slide groove 82 respectively. The upper end of the connecting piece 87 is rotatably connected to the middle of the bottom of the gluing lower plate 3.

[0044] Among them, the first slide groove 81 and the second slide groove 82 are interconnected, so that the connecting piece 87 can pass through the first slide groove 81 for horizontal movement, and the slide plate 88 can pass through the second slide groove 82 for longitudinal movement, and the width of the first slide groove 81 is smaller than that of the second slide groove 82, and the slide plate 88 will not enter the first slide groove 81.

[0045] Specifically, when the circulating pushing mechanism 8 is working, the second motor 83 drives the rotating arm 84 to rotate, and then the rotating arm 84 drives the swing arm 86 to rotate, so that the slide plate 88 at one end of the swing arm 86 slides in the second slide groove 82, and the connecting piece 87 at the other end of the swing arm 86 slides in the first slide groove 81. The connecting piece 87 is connected to the bottom middle part of the upper gluing lower plate 3, so that the upper gluing lower plate 3 moves in the gluing platform 1, and drives the laser cardboard to move, which is convenient for replacement.

[0046] The present invention provides an environment-friendly laser paper gluing device and a gluing method thereof. A smoothing device 7 is provided. Driven by a first motor 74, a circular pushing mechanism 71 can drive a bottom gluing upper plate 4 to move in a circular shape. After the glue is discharged from a glue outlet 6, the glue is evenly spread after the circular movement of the gluing upper plate 4. This prevents the glue on the surface of the laser paper from being accumulated after gluing. The gluing is more evenly applied, thereby improving the gluing quality and efficiency.

[0047] The present invention is provided with a circulating pushing mechanism 8. Driven by the second motor 83, the rotating arm 84 drives the swinging arm 86 to move circumferentially and rotate at the same time, so that one end of the rotating arm 84 moves in the first slide groove 81, and the other end moves in the second slide groove 82, synchronously driving the gluing lower plate 3 to move in the gluing platform 1. After the gluing lower plate 3 is moved out of the bottom of the smearing device 7, it is convenient to replace the laser cardboard before and after gluing without manual pushing, which is convenient, fast and more efficient.

Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
