Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0025] Embodiment 1

[0026] Referring to Figures 1 - 3 , a glue - applying device for corrugated cardboard production, including a bottom chassis 5 and a corrugated cardboard conveyor 7. The corrugated cardboard conveyor 7 is installed and connected to the middle of the inner side of the upper end of the bottom chassis 5. The corrugated cardboard can be conveyed through the corrugated cardboard conveyor 7. A hollow housing 4 is fixed on the bottom chassis 5 above the corrugated cardboard conveyor 7. The glue - applying smoothing mechanism 8 is fixedly connected to the rear end of the hollow housing 4, so that the glue evenly dripped and distributed on the corrugated cardboard can be smoothed, enabling the corrugated cardboard to be evenly coated with glue. A corrugated conveying pipe 11 is installed in the middle of the hollow housing 4. Due to the telescopic property of the corrugated conveying pipe 11, there will be no obstruction during adjustment. The pump conveying pipe 21 is installed at the upper end of the corrugated conveying pipe 11, and the glue - applying conveying pump 2 is installed at the outer end of the pump conveying pipe 21. Thus, the glue conveyed by the glue - applying conveying pump 2 can be conveyed into the corrugated conveying pipe 11 through the pump conveying pipe 21. The glue - applying conveying tank body 1 is installed on the outer side of the upper end of the glue - applying conveying pump 2, so that the glue inside the glue - applying conveying tank body 1 can be extracted for glue - applying. The adjustable auxiliary conveying roller body 6 is installed on the bottom chassis 5 in front of the hollow housing 4. When the corrugated cardboard is located below the adjustable auxiliary conveying roller body 6, it plays a blocking role, so that the corrugated cardboard can be stably conveyed and used;

[0027] On both sides of the corrugated conveying pipe 11, lifting telescopic cylinders 10 are installed at the inner top end of the hollow housing 4. At the lower ends of the corrugated conveying pipe 11 and the lifting telescopic cylinders 10, there is a hollow glue - applying plate 9. Thus, the telescopic rod of the lifting telescopic cylinder 10 can drive the hollow glue - applying plate 9 to lift and lower during telescoping, so that it can be adjusted according to the thickness of the corrugated cardboard. The corrugated conveying pipe 11 is telescopic, so there will be no obstruction during telescoping. An array of glue - applying drip holes 3 is opened on the inner side of the lower end of the hollow glue - applying plate 9. Thus, the glue conveyed by the corrugated conveying pipe 11 can be transported into the hollow glue - applying plate 9, and then the glue can be dripped and applied through the glue - applying drip holes 3 at the lower end of the hollow glue - applying plate 9. A drip - hole plug 12 is sleeved and installed inside the glue - applying drip hole 3. In this way, personnel can adjust the glue - dripping range of the hollow glue - applying plate 9 according to the plugging of the drip - hole plug 12;

[0028] The number of drip - hole plugs 12 corresponds to the number of holes of the glue - applying drip holes 3, so that it can be adjusted, disassembled and used according to needs.

[0029] In the present utility model, the hollow housing 4 and the bottom chassis 5 are connected by welding, and the connection parts are aligned, so that they can be installed and fixed. And the alignment of the connection parts will not cause obstruction during use.

[0030] In the present utility model, two lifting telescopic cylinders 10 are provided, and the lifting telescopic cylinders 10 are symmetrically installed on the inner top end of the hollow housing 4. Thus, the lifting telescopic cylinders 10 can stably lift and lower in the hollow housing 4.

[0031] Embodiment Two

[0032] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in, the glue - applying and leveling mechanism 8 includes a leveling scraper 81, a welding convex plate 82, a leveling smooth plate 83, an assembly bolt 84, a bottom sleeve 85 and an electric telescopic cylinder 86. The welding convex plate 82 is installed and connected to the hollow housing 4, so that it can be stably placed. The lower end of the welding convex plate 82 is fixed with a bottom sleeve 85. The inner side of the lower end of the bottom sleeve 85 is sleeved with an electric telescopic cylinder 86. The bottom sleeve 85 and the electric telescopic cylinder 86 are installed and connected by an assembly bolt 84. Thus, by tightening and loosening the assembly bolt 84, the electric telescopic cylinder 86 can be installed and disassembled. The lower end of the telescopic rod of the electric telescopic cylinder 86 is installed with a leveling scraper 81, and the lower end of the leveling scraper 81 is fixed with a leveling smooth plate 83. Thus, when the telescopic rod of the electric telescopic cylinder 86 telescopes, it can change the position height of the leveling scraper 81 and the leveling smooth plate 83, so that it can be adjusted according to the thickness of the corrugated cardboard, making the lower end of the leveling smooth plate 83 align with the top end of the corrugated cardboard. Thus, the glue on the corrugated cardboard can be leveled during glue - dripping and conveying.

[0033] In the present utility model, the glue - applying and conveying tank body 1 includes a box cover 101, an extraction and conveying pipe 102, a tank body outer shell 103, and a welding vertical plate 104. The welding vertical plate 104 is fixedly connected to the bottom chassis 5, so that it can be stably placed. The upper end of the welding vertical plate 104 is provided with the tank body outer shell 103. The extraction and conveying pipe 102 is fixed inside the tank body outer shell 103. The extraction and conveying pipe 102 is connected to the glue - applying and conveying pump 2. Thus, the glue - applying and conveying pump 2 can extract the glue inside the tank body outer shell 103 through the extraction and conveying pipe 102 for conveying. The box cover 101 is rotatably installed at the upper - end feed hole of the tank body outer shell 103. In this way, personnel can add glue by disassembling the box cover 101.

[0034] Embodiment Three

[0035] Referring to Figure 1 and Figure 5 The adjustable auxiliary conveying roller body 6 includes a rotating roller body 61, a positioning bearing block 62, a mounting panel 63, and a lifting bolt 64. The mounting panel 63 is rotatably threaded around the circumferential side of the lifting bolt 64 and is installed and connected to the bottom chassis 5 by screws. Thus, the lifting bolt 64 can rotate and lift in the mounting panel 63. The upper end of the positioning bearing block 62 is rotatably installed with the lifting bolt 64. Thus, when the lifting bolt 64 rotates and lifts, it can drive the positioning bearing block 62 to lift. The two ends of the rotating roller body 61 are installed with the positioning bearing blocks 62. Thus, the positioning bearing blocks 62 can drive the rotating roller body 61 to lift. In this way, the auxiliary height position of the rotating roller body 61 can be effectively changed, so that it can be adjusted according to the thickness of the corrugated cardboard for use.

[0036] Working principle: During use, personnel place the corrugated cardboard on the corrugated cardboard conveyor 7 above the bottom chassis 5 and convey it under the adjustable auxiliary conveying roller body 6. When the corrugated cardboard is conveyed under the hollow cover 4 and below the hollow glue - applying plate 9, the glue - applying and conveying pump 2 extracts the glue inside the glue - applying and conveying tank body 1 and conveys it through the pump pipe 21 to the corrugated conveying pipe 11. Thus, the glue conveyed by the corrugated conveying pipe 11 can be conveyed into the hollow glue - applying plate 9. Then, through the glue - dripping holes 3 at the lower end of the hollow glue - applying plate 9, glue can be dripped for glue - applying, so that it can be evenly distributed on the surface of the corrugated cardboard. After that, the corrugated cardboard is conveyed. When it is conveyed under the glue - applying and leveling mechanism 8, it can be evenly smeared with glue through the glue - applying and leveling mechanism 8, thus completing the glue - applying.
