[0032] The following is combined with Figures 1 to 5 The embodiments of this utility model are described below.

[0033] This utility model embodiment provides a glue spraying machine, including:

[0034] frame;

[0035] X-axis displacement mechanism 100 includes a first motor 101, a first guide rail 102, and a first slider 103. The first guide rail 102 is fixedly mounted on the frame and extends along the X-axis. The first slider 103 is movably mounted on the first guide rail 102 and is driven by the first motor 101, moving along the first guide rail 102 on the X-axis.

[0037] Z-axis displacement mechanism 300 includes cylinder 301, piston 302 and third slider 303. The cylinder body of cylinder 301 is fixedly mounted on second slider 203. Cylinder 301 extends along the Z-axis direction. Piston 302 is movably mounted inside cylinder 301. Third slider 303 is driven by piston 302 and moves along cylinder 301 on the Z-axis.

[0038] A glue spraying mechanism 400 is mounted on the third slider 303 and is used to spray glue onto the cardboard 600.

[0039] A pushing mechanism 500 is mounted on the frame and located below the active area of ​​the glue spraying mechanism 400. The pushing mechanism 500 pushes the cardboard 600 to be sprayed with glue along the X-axis.

[0040] In this embodiment, the first motor 101 drives the first slider 103 to move along the first guide rail 102 on the X-axis, realizing the precise positioning of the glue spraying mechanism 400 in the horizontal direction. The structure is simple and the control precision is high, which is suitable for the continuous operation requirements of glue spraying on cardboard 600. On this basis, the Y-axis displacement mechanism 200 and the X-axis displacement mechanism 100 form a two-dimensional linkage, which expands the planar movement range of the glue spraying mechanism 400 and can cover the glue spraying needs of different areas of cardboard 600. In the Z-axis displacement mechanism 300, the cylinder 301 drives the third slider 303 to rise and fall along the Z-axis. The structure is compact and the power is strong. The height of the glue spraying gun 401 can be quickly adjusted to adapt to cardboard 600 of different thicknesses.

[0041] In this embodiment, the three-dimensional spatial positioning of the glue spraying mechanism 400 is achieved through three-axis linkage, ensuring the flexibility of the glue spraying path and meeting the complex glue spraying process requirements in the production of the cardboard 600 book.

The positioning adjustment block 304 has a positioning adjustment groove 3041 extending along the Z-axis. The third slider 303 has a positioning hole 3031. The positioning adjustment pin passes through the positioning adjustment groove 3041 and is threadedly connected to the positioning hole 3031. The spray gun connecting block 402 is connected to the positioning adjustment block 304.

[0045] In this embodiment, the position of the glue gun 401 in the Z-axis direction can be finely adjusted according to the actual glue spraying requirements through the cooperation of the positioning adjustment block 304 and the positioning adjustment pin, thereby accurately controlling the distance between the glue gun 401 and the cardboard 600 and improving the glue spraying quality and effect.

[0046] Furthermore, the piston 302 extends along the Z-axis to divide the cylinder 301 into a first sealing cavity 3011 and a second sealing cavity 3012. The cylinder body of the cylinder 301 is provided with a first air hole 3013 and a second air hole 3014. The first air hole 3013 communicates with the first sealing cavity 3011, and the second air hole 3014 communicates with the second sealing cavity 3012.

[0047] In this embodiment, the cylinder 301 is divided into two sealed chambers and corresponding air holes are provided. By controlling the air intake and exhaust of different air chambers, the movement of the piston 302 can be precisely controlled, thereby achieving stable movement of the third slider 303 in the Z-axis direction.

[0048] Furthermore, the X-axis displacement mechanism 100 also includes a first lead screw (not shown in the figure) and a first nut (not shown in the figure).

The first lead screw and the first nut are threadedly engaged, driving the first slider 103 to move along the first guide rail 102 on the X-axis.

[0049] This embodiment utilizes the high precision, high stability, and high load-bearing capacity of the lead screw and nut transmission to accurately convert the rotational motion of the first motor 101 into the linear motion of the first slider 103, ensuring the accuracy and reliability of displacement in the X-axis direction and improving the working quality of the glue spraying machine.

[0050] Furthermore, the Y-axis displacement mechanism 200 also includes a second lead screw (not shown in the figure) and a second nut (not shown in the figure).

The second lead screw and the second nut are threadedly engaged, driving the second slider 203 to move along the second guide rail 202 on the Y-axis.

[0051] In this embodiment, the Y-axis displacement mechanism 200 is similar to the X-axis displacement mechanism 100, and adopts a lead screw and nut drive to ensure the precise movement of the second slider 203 in the Y-axis direction. In conjunction with the X-axis displacement mechanism 100, it realizes the precise positioning of the glue spraying mechanism 400 in the plane and meets the glue spraying requirements at different positions.

[0052] Furthermore, the X-axis displacement mechanism 100 also includes a first connecting block 104, a first guide block 105, and a third guide rail 106.

[0053] In this embodiment, the third guide rail 106 and the first guide block 105 provide additional guidance and support for the movement of the first slider 103 in the X-axis direction. The dual guide rails enhance the stability and straightness of the movement of the first slider 103, reduce the shaking and deviation during the movement, and improve the overall accuracy of the glue spraying machine.

[0054] Furthermore, the Y-axis displacement mechanism 200 also includes a second connecting block 204, a second guide block 205, and a fourth guide rail 206. The fourth guide rail 206 is fixedly mounted on the frame and extends along the Y-axis direction. The second guide block 205 is movably mounted on the fourth guide rail 206 and is connected to the second slider 203 through the second connecting block 204.

[0055] In this embodiment, the Y-axis displacement mechanism 200 is similar to the X-axis displacement mechanism 100. The double guide rail configuration provides stable guidance and support for the movement of the second slider 203 in the Y-axis direction, ensuring the smoothness and accuracy of the movement of the second slider 203, and further improving the positioning accuracy of the glue spraying machine in the plane.

The pushing chain 501 is located between the first pushing guide rail 502 and the second pushing guide rail 503. The pushing chain 501 is provided with a plurality of pushing flag fixing holes (not shown in the figure).

The pushing flag fixing pin 505 passes through the pushing flag positioning hole and connects to the pushing flag fixing hole. The third motor is installed on the frame, and the third motor drives the pushing chain 501 to perform cyclic movement along the X-axis direction.

[0057] In this implementation, the pushing mechanism 500 can stably push the cardboard 600 to be sprayed with glue. The pushing interval can be installed and adjusted according to the pushing rhythm, which improves the versatility and applicability of the equipment.
