[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. When producing cartons, a glue coating device is required for glue coating. During the production process of cartons, glue is applied to the cardboard and then assembled.

[0003] Some devices on the market generally include a glue storage tank, a glue outlet, a sliding rod, and a glue wiping board. That is, the cardboard to be glued is placed on the conveyor belt, and the cardboard slowly moves forward with the conveyor belt. At the same time, the glue in the glue storage tank is controlled to drip evenly from the glue outlet. When the cardboard is completely dripped with glue, the conveyor belt is controlled to stop. Then, the sliding rod is slid, and the glue wiping board is controlled to slide evenly in the chute. After the glue on the cardboard is evenly applied by the glue wiping board, the sliding rod is then controlled to slide backward along the direction of the chute.

[0004] However, in the actual use process of the above-mentioned device, the water glue smeared on the outer surface of the cardboard may adhere to the glue wiping board, resulting in the cardboard being difficult to separate from the glue wiping board due to adhesion, and the cardboard is easily damaged. In view of this, we have proposed a glue coating device that can prevent adhesion. Content of the Utility Model

The number of the installation parts is two, and the two installation parts are symmetrically arranged with respect to the center of the collection groove, so that the limiting rollers arranged on the side of the installation part can well limit the cardboard.

[0010] Preferably, the position of the electric push rod corresponds to the position of the mounting member, and the end of the electric push rod penetrates through the side of the machine body and is fixedly connected to the mounting member, so that the electric push rod can well control the movement of the mounting member.

[0011] Preferably, the size of the limiting roller is adapted to the size inside the mounting member. The number of the limiting rollers is set to three groups, and the three groups of limiting rollers are evenly distributed in a linear array inside the mounting member, so that the limiting rollers can well limit and transmit the cardboard.

[0012] Preferably, a placement groove is formed in the side of the mounting member. A large spring is fixedly connected to the top of the inner wall of the placement groove.

Specific embodiments

[0024] As Figures 1-6 shown, the present utility model provides a technical solution: a glue coating device that can prevent adhesion, including a machine body 1, a transmission roller 2 is rotatably connected to the inner wall of the machine body 1, a collection tank 5 is opened at the bottom of the inner wall of the machine body 1, an electric telescopic rod 3 is fixedly connected to the top of the machine body 1, a glue coating device 4 is fixedly connected to the end of the electric telescopic rod 3, and the glue coating transmission pipe arranged on the upper surface of the glue coating device 4 passes through the side of the machine body 1, so that the glue coating device 4 can coat the cardboard for a long time. A limiting component is arranged on the side of the machine body 1, and the limiting component includes an electric push rod 6, a mounting part 7, a mounting groove 8, a small spring 9, a mounting block 10 and a limiting roller 11.

[0025] In an embodiment of the present utility model, an electric push rod 6 is fixedly connected to the side of the machine body 1. The position of the electric push rod 6 corresponds to the position of the mounting member 7. The end of the electric push rod 6 penetrates through the side of the machine body 1 and is fixedly connected to the mounting member 7. In this way, the electric push rod 6 can well control the movement of the mounting member 7. The end of the electric push rod 6 is fixedly connected to the mounting member 7. The mounting member 7 is arranged in a U shape. The mounting member 7 is arranged inside the collection groove 5. The number of the mounting members 7 is two, and the two mounting members 7 are symmetrically arranged with respect to the center of the collection groove 5. In this way, the limiting rollers 11 arranged on the side of the mounting member 7 can well limit the cardboard. An installation groove 8 is opened at the bottom of the inner wall of the mounting member 7. A small spring 9 is fixedly connected to the installation groove 8. The end of the small spring 9 is fixedly connected to an installation block 10. The top of the installation block 10 is rotatably connected to a limiting roller 11. The outer surface of the limiting roller 11 is arranged in an arc shape. The size of the limiting roller 11 is adapted to the size inside the mounting member 7. The number of the limiting rollers 11 is set to three groups, and the three groups of limiting rollers 11 are evenly distributed in the mounting member 7 in a linear array. The limiting rollers 11 are evenly distributed in the mounting member 7 in a linear array. In this way, the limiting rollers 11 can well limit and convey the cardboard.

[0026] Furthermore, a placement groove 12 is opened on the side of the mounting member 7. A large spring 13 is fixedly connected to the top of the inner wall of the placement groove 12. The end of the large spring 13 is fixedly connected to a placement block 14. A scraping plate 15 is slidably connected to the side of the placement block 14. A scraping strip 16 is fixedly connected to the bottom of the scraping plate 15. The scraping strip 16 is arranged in a right trapezoid shape. The side of the scraping plate 15 is arranged in an arc shape. A chute is opened on the side of the scraping plate 15, and the placement block 14 is clamped inside the chute. In this way, when the mounting member 7 is moved by the electric push rod 6, the placement block 14 moves inside the chute opened on the side of the scraping plate 15. In this way, the elastic force of the large spring 13 can push the placement block 14 to move downward, so that the scraping plate 15 presses downward, and the right trapezoid scraping strip 16 arranged at the bottom of the scraping plate 15 can well contact the upper surface of the cardboard. This can enable the scraping plate 15 to well scrape off the excess glue on the upper surface of the cardboard and drop it into the collection groove 5, so that the cardboard can be evenly coated with glue.

[0027] In the present utility model, during use, the cardboard is placed on the outer surface of the transmission roller 2, and the transmission roller 2 conveys the cardboard to the lower part of the gluing device 4. At this time, the electric telescopic rod 3 extends to enable the gluing device 4 to apply glue to the cardboard. Moreover, the glue transmission pipe arranged on the upper surface of the gluing device 4 passes through the side of the machine body 1. In this way, the gluing device 4 can apply glue to the cardboard for a long time. After the cardboard is coated with glue, the electric push rod 6 extends to make the mounting member 7 approach the side of the cardboard, so that the outer surface of the limiting roller 11 contacts the side of the cardboard. The elastic force of the small spring 9 enables the limiting roller 11 to better contact the cardboard and can effectively prevent the cardboard from being damaged due to excessive pressure. At the same time, the limiting of the cardboard by the limiting roller 11 can effectively separate the cardboard from the gluing device 4.

[0028] Furthermore, when the installation part 7 is moved by the electric push rod 6, the placement block 14 moves inside the chute opened on the side of the scraping plate 15. In this way, the elastic force of the large spring 13 can push the placement block 14 downward, so that the scraping plate 15 is pressed downward, enabling the right trapezoidal scraping strip 16 provided at the bottom of the scraping plate 15 to come into good contact with the upper surface of the cardboard. This allows the scraping plate 15 to well scrape off the excess glue on the upper surface of the cardboard and drop it into the collection tank 5, making the cardboard evenly coated with glue.

[0029] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
