Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Referring to Figures 1-8 , the glue automatic coating device of the carton - sticking machine includes a transportation equipment 1. The outer bottom wall of the transportation equipment 1 is rotatably installed with a double - headed screw 3 through a moving frame 2. The outer wall of the moving frame 2 is fixedly installed with a motor 4 connected to the double - headed screw 3. The outer wall of the double - headed screw 3 is threadedly installed with two moving sleeves 6 through a limiting mechanism. The limiting mechanism includes a limiting rod 5 fixedly installed inside the moving frame 2. The limiting rod 5 slidably penetrates through the two moving sleeves 6. The limiting rod 5 can play a limiting role on the two moving sleeves 6, so that the two moving sleeves 6 can only axially move along the outer wall of the double - headed screw 3. The upper end surfaces of the two moving sleeves 6 are fixedly connected with a connecting plate 8 through a connecting mechanism. The connecting mechanism includes a connecting rod 7 fixedly installed on the upper end surface of the moving sleeve 6. The end of the connecting rod 7 is fixedly connected to the outer wall of the connecting plate 8. The upper end surface of the moving frame 2 is provided with a first moving opening for cooperating with the connecting rod 7.

[0028] On the inner walls of both of the two connecting plates 8, a positioning frame 10 is fixedly connected through an elastic mechanism. The elastic mechanism includes two spring telescopic rods 9 fixedly installed on the inner wall of the connecting plate 8. The telescopic ends of the two spring telescopic rods 9 are fixedly connected to the outer wall of the positioning frame 10. A plurality of positioning rollers 11 are rotatably installed inside each of the two positioning frames 10. On the upper end surface of the transportation device 1, a support frame 12 is fixedly installed. A second moving opening for cooperating with the connecting rod 7 is formed on the outer wall of the support frame 12. The bottom wall of the support frame 12 is fixedly connected to a connecting plate 14 through a lifting mechanism. The lifting mechanism includes a cylinder 13 fixedly installed on the bottom wall of the support frame 12. The telescopic end of the cylinder 13 is fixedly connected to the upper end surface of the connecting plate 14.

[0029] On the upper end surface of the connecting plate 14, two stabilizing rods 15 are fixedly installed. Both of the two stabilizing rods 15 slidably penetrate through the support frame 12. On the bottom wall of the connecting plate 14, a glue coating device 16 is fixedly installed. On the bottom wall of the connecting plate 14, a pressing frame 18 is fixedly installed through a fixing mechanism. The fixing mechanism includes two fixing rods 17 fixedly installed on the bottom wall of the connecting plate 14. The ends of the two fixing rods 17 are fixedly connected to the upper end surface of the pressing frame 18. A pressing roller 19 is rotatably installed inside the pressing frame 18. On the upper end surface of the connecting plate 14, a blower 20 is fixedly installed. On the outer wall of the outlet pipe of the blower 20, a blowing pipe 21 is fixedly installed. Blowing openings communicating with the inside are formed on the outer wall of the blowing pipe 21.

[0030] When the utility model is in use, the transportation device 1 can transport the carton. During the transportation process, the motor 4 can drive the double-headed screw rod 3 to rotate. The double-headed screw rod 3 can drive the two moving sleeves 6 to move through the cooperation with the limiting rod 5. The two moving sleeves 6 then drive the connecting rods 7 on the same side to move respectively. Thus, the two positioning frames 10 can approach each other, and the carton can be clamped and positioned by a plurality of positioning rollers 11 rotatably installed on both sides. Thus, the carton can be prevented from shifting during transportation. And when clamping and positioning the carton, through the elastic cooperation of the spring telescopic rods 9, the clamping force can be elastically adjusted to avoid damaging the carton due to excessive clamping force.

[0031] At the same time, the cylinder 13 can drive the connecting plate 14 to move downward. The connecting plate 14 then drives the two stabilizing rods 15 to slide on the bottom wall of the support frame 12. Thus, the stability of the connecting plate 14 during movement can be increased. At this time, the connecting plate 14 can drive the pressing frame 18 to move through the cooperation of the fixing rods 17. The pressing frame 18 then drives the pressing roller 19 to move into contact with the upper end surface of the carton. Thus, the upper end surface of the carton can be flattened during transportation to avoid the phenomenon of warping edges affecting the glue coating effect. When the carton moves below the glue coating device 16, the glue coating device 16 can coat the carton with glue. After the glue coating is completed, then with the continuous transportation of the transportation device 1, at the same time, the blower 20 can blow cold air into the blowing pipe 21. The cold air then blows out from the inside of the blowing pipe 21 through the blowing openings. Thus, the solidification speed of the glue can be increased, and thus the glue coating efficiency of the carton can be improved.

[0032] As described above, it is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
