Since the mounting frame is in an "L" shape, the glue spraying head can move to the bottom of the gear box. Since the screw direction of the screw rod is the same, the mounting frames on both sides are avoided from colliding. The glue spraying head can spray glue on wider non-woven fabrics, which is suitable for promotion. However, the glue sprayed by the nozzle may sometimes not be sprayed evenly due to some problems, and the thickness of the glue spraying coating on the non-woven fabric cannot be controlled. If the glue spraying is uneven, the glue in some areas may be too little, resulting in weak bonding, which may reduce the durability and strength of the non-woven fabric.

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention; the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance; in addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-5 As shown, the utility model proposes a glue spraying device for non-woven fabric production, including a machine table 1 and a glue barrel 2, the glue barrel 2 is arranged above the machine table 1, and also includes two glue spraying heads 5, two scrapers 6 and two glue connecting boxes 7. A driving mechanism 3 is arranged in the machine table 1, and the driving mechanism 3 includes two brackets 31, the two brackets 31 are arranged in the machine table 1, the two glue spraying heads 5 and the two scrapers 6 are respectively arranged on the two brackets 31, and the two glue connecting boxes 7 are respectively connected to the bottom ends of the two scrapers 6. A heating frame 8 is arranged at the top of the machine table 1, and the glue barrel 2 is arranged in the heating frame 8. A placing table 9 is arranged on the bottom wall of the machine table 1, and a pressing roller 4 is arranged between the two brackets 31.

[0022] In the utility model, both the front and rear sides of the machine 1 are missing. The nonwoven fabric is put into the machine from the front side. During the transportation process, the nonwoven fabric is generally transported by conveying rollers. When transporting, it will pass through the placement table 9. When the nonwoven fabric is on the placement table 9, the pressure roller 4 is driven downward by the driving mechanism 3 to fit the nonwoven fabric and fix the nonwoven fabric. At the same time, the two glue spraying heads 5 are moved to spray glue on nonwoven fabrics of different widths. The glue spraying heads 5 are connected to the glue barrel 2 through a hose. No matter how the two glue spraying heads 5 are moved by the driving mechanism 3, the glue barrel 2 can transport the two glue spraying heads 5. Glue, because the scraper 6 is located at the rear side of the glue spraying head 5, after the glue is sprayed, the glue sprayed is uneven and the thickness is different. During the non-woven fabric conveying process, the scraper 6 is adjusted to a certain height to scrape off the uneven glue and scrape the glue into the same thickness. Since the glue box 7 is connected to the bottom end of the scraper 6, and the scraper 6 is in an "L" shape, it is convenient to scrape the excess glue into the glue box 7 to prevent the glue from being sprayed too much and flowing onto the machine 1 or sticking to other non-woven fabrics, which is difficult to handle. By using the heating frame 8 to heat the glue in the glue barrel, the heated glue can reduce its viscosity and make the glue easier to flow. In this way, when the glue passes through the nozzle, it can cover the target surface more evenly and form a thinner coating. Since the heated glue has better fluidity, it is less likely to be blocked at the nozzle, and the stirring effect in the glue barrel 2 is also better.

[0023] In an optional embodiment, the driving mechanism 3 also includes a hydraulic cylinder 32, a moving frame 33, a connecting frame 34 and a translation assembly 35. The hydraulic cylinder 32 is arranged at the top of the machine platform 1, and the telescopic rod is vertically downward. The moving frame 33 is connected to the bottom end of the telescopic rod of the hydraulic cylinder 32, the connecting frame 34 is connected to the bottom end of the moving frame 33, and the translation assembly 35 is arranged in the moving frame 33, and drives the two brackets 31 to move relative to or away from each other.

[0024] In an optional embodiment, the translation assembly 35 includes a motor 351 and a bidirectional threaded rod 352. The motor 351 is arranged on the right side of the moving frame 33. One end of the bidirectional threaded rod 352 is coaxially connected to the output shaft of the motor 351, and the other end is rotatably connected to the left side wall of the moving frame 33. The two connecting frames 34 are both threadedly connected to the bidirectional threaded rod 352.

[0025] It should be noted that the movable frame 33 is driven to move up and down by using a hydraulic cylinder 32. Sliding windows that are compatible with the size of the movable frame 33 are provided on the left and right sides of the machine 1 to limit the movable frame 33 to prevent it from shifting when moving up and down. The pressure roller 4 is connected to the bottom end of the movable frame 33 through two connecting frames 34. The pressure roller 4 is rotatably connected to the two connecting frames. When the movable frame 33 moves downward, the pressure roller 4 also moves downward. A translation component 35 is arranged inside the movable frame 33. By starting the motor 351 to drive the bidirectional threaded rod 352 to rotate, the two brackets 31 can be moved relative to or away from each other, thereby driving the glue spray head 5, the scraper 6 and the glue box 7 to move to cope with non-woven fabrics of different widths.

[0026] In an optional embodiment, a threaded sleeve 62 is provided on the connecting frame 34 , a threaded rod 61 is connected to the top end of the scraper 6 , and the threaded rod 61 is threadedly connected to the threaded sleeve 62 .

[0027] It should be noted that, by using the threaded sleeve 62 and the threaded rod 61 in cooperation, the scraper 6 can be further fine-tuned, and the scraper 6 and the glue receiving box 7 can be removed to pour out the received glue.

[0028] In an optional embodiment, the inner wall of the heating frame 8 is connected to a heating plate 81 , the glue barrel 2 is located on the inner side of the heating plate 81 , and the top of the heating frame 8 is connected to a water inlet pipe.

[0029] It should be noted that, by adding a heat-conducting medium into the water inlet phase heating frame 8 and heating it through the heating plate 81, the glue barrel 2 can be heated and the glue can be heated appropriately.

[0030] In an optional embodiment, a placement groove is provided on the placement table 9 , a widening plate 91 is provided in the placement groove, and the widening plate 91 and the placement table 9 are located in the same horizontal plane.

[0031] It should be noted that by increasing or decreasing the number of widening plates 91 , nonwoven fabrics of different widths can be accommodated.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
