Description

Technical Field

[0001] This utility model relates to the field of carton sealing machine technology, and in particular to a dual-axis independent glue spraying carton sealing machine. Background Technology

[0002] A carton sealing machine is a type of packaging equipment mainly used for automating the carton sealing process. It securely seals the top and bottom of a carton by spraying glue, and is commonly used for sealing cartons in production lines. The carton is conveyed to the glue spraying position via a conveyor belt, and the glue spraying structure evenly sprays glue onto the edges of the carton to ensure a secure seal.

[0003] Most existing glue spraying and sealing machines are single-axis glue spraying machines, meaning they only have one glue spraying structure. When spraying glue on multiple boxes, they need to wait for the previous box to finish spraying, which greatly affects the glue spraying efficiency. Moreover, after the box is finished spraying glue, the top flap needs to be pressed tightly using a compaction structure. However, the existing compaction structure is a flat plate, which has high friction with the box and can easily affect the box conveying. Therefore, those skilled in the art have provided a dual-axis independent glue spraying and sealing machine to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual-axis independent glue spraying and sealing machine. The two glue spraying heads can improve the sealing efficiency, and the smoothing mechanism can enhance the adhesion of the glue.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-axis independent glue spraying and sealing machine, comprising a conveyor belt, slide bars, four electric telescopic rods and glue spraying heads. A smoothing mechanism is fixedly installed at the rear position between the two end faces of the conveyor belt. Slide cylinders are slidably sleeved at the front position of the outer end faces of the two slide bars. Vertical blocks are fixedly installed on the upper end faces of the two slide cylinders. Lead screws are rotatably installed between the front inner walls and the rear inner walls of the two slide bars. Threaded blocks are threadedly sleeved at the front position of the outer end faces of the two lead screws. Adjustment blocks are fixedly installed on the lower end faces of the two glue spraying heads.

[0006] The smoothing mechanism includes a smoothing plate, a housing, and a push spring. A main plate is fixedly installed at the middle position of the upper end face of the smoothing plate. Multiple rollers are rotatably installed inside the smoothing plate. Side plates are fixedly installed on both sides of the upper end face of the smoothing plate.

[0007] Furthermore, vertical rods are fixedly installed on the front and rear sides of both ends of the conveyor belt, and the two sliding cylinders are respectively fixedly connected to the two threaded blocks.

[0008] Furthermore, support rods are fixedly installed at the front and rear positions of the middle of both ends of the conveyor belt, and the four electric telescopic rods are respectively fixedly installed on the upper end face of the four support rods.

[0009] Furthermore, the two slide rods are respectively fixedly installed at the output ends of the four electric telescopic rods, and the two adjusting blocks are respectively hinged to the inner walls of the two vertical blocks.

[0010] Furthermore, a micro motor is fixedly installed on the upper side of the front end face of each vertical block, and the output end of the micro motor is fixedly installed on the front end face of the two adjustment blocks respectively.

[0011] Furthermore, a small motor is fixedly installed on the front end face of each of the two slide rods, and the output ends of the two small motors are respectively fixedly installed on the front end face of the two lead screws.

[0012] Furthermore, side grooves are provided on both sides of the top surface of the box, and the two side plates are slidably disposed on the inner walls of the two side grooves respectively.

[0013] Furthermore, a buffer groove is provided in the middle of the top surface of the box, the main board is slidably disposed on the inner wall of the buffer groove, and the push spring is fixedly disposed between the main board and the buffer groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a dual-axis independent glue spraying and sealing machine. The conveyor belt is equipped with slide bars on both sides. The box moves backward continuously on the conveyor belt. The rotating screw drives the glue spraying head to move along with the slide bar and slide cylinder, making the glue spraying of the box more distinct. The glue spraying head can swing inside the vertical block to facilitate spraying at different angles. The height of the glue spraying head can be adjusted by the electric telescopic rod. Moreover, the glue spraying head on both sides can improve the sealing efficiency.

[0016] 2. The present invention proposes a dual-axis independent glue spraying and sealing machine. After the glue spraying is completed, the box will enter the box body. The flip-top on the box is pressed down by the flat plate. Rollers are set below the flat plate to reduce the friction between the box and the flat plate and prevent the box from getting stuck inside the box body. A main plate is set above the flat plate. The main plate is pushed by a push spring to press the box tightly, so that the glue on the box has a better adhesion effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 2 , Figure 3 An embodiment of this utility model is provided: a dual-axis independent glue spraying and sealing machine, including a conveyor belt 7, slide rods 12, four electric telescopic rods 6 and glue spraying heads 4. A smoothing mechanism 1 is fixedly installed at the rear position between the two end faces of the conveyor belt 7. Slide cylinders 10 are slidably sleeved at the front position of the outer end face of the two slide rods 12. Vertical blocks 13 are fixedly installed on the upper end face of the two slide cylinders 10. Screws 3 are rotatably installed between the front inner wall and the rear inner wall of the two slide rods 12. Threaded blocks 14 are threadedly sleeved at the front position of the outer end face of the two screws 3. Adjusting blocks 11 are fixedly installed on the lower end face of the two glue spraying heads 4.

[0025] Vertical rods 8 are fixedly installed on the front and rear sides of both ends of the conveyor belt 7. Two sliding cylinders 10 are fixedly connected to two threaded blocks 14 respectively. Support rods 9 are fixedly installed on the front and rear sides of the middle of both ends of the conveyor belt 7. Four electric telescopic rods 6 are fixedly installed on the upper end face of the four support rods 9 respectively. Two sliding rods 12 are fixedly installed on the output end of the four electric telescopic rods 6 respectively. Two adjusting blocks 11 are hinged to the inner wall of the two vertical blocks 13 respectively. Micro motors 2 are fixedly installed on the upper side of the front end face of the vertical blocks 13 respectively. The output end of the micro motors 2 is fixedly installed on the front end face of the two adjusting blocks 11 respectively. Small motors 5 are fixedly installed on the front end face of the two sliding rods 12 respectively. The output end of the two small motors 5 is fixedly installed on the front end face of the two lead screws 3 respectively.

[0026] Specifically, when sealing the box, the box is placed on the conveyor belt 7. The activated conveyor belt 7 will drive the box backward. The activated small motor 5 will drive the lead screw 3 to rotate. The rotating lead screw 3 will drive the slide cylinder 10 to slide on the slide rod 12 through the threaded block 14, thereby driving the glue spray head 4 to move back and forth, so as to facilitate glue spraying on the box at different positions. The box is continuously driven backward by the conveyor belt 7, and the glue spray head 4 moves along with it. The activated micro motor 2 drives the adjusting block 11 to rotate on the inner wall of the vertical block 13, thereby adjusting the angle of the glue spray head 4, so that different angles can be sprayed. The glue spray head 4 sprays glue onto the box. Moreover, glue spray heads 4 are set on both sides of the conveyor belt 7. The two glue spray heads 4 can spray separately, making the glue spraying efficiency of the box higher. The box is continuously conveyed by the conveyor belt 7 to the smoothing mechanism 1, and the activated electric telescopic rod 6 can pull the slide rod 12 to adjust the glue spraying height.

[0027] Reference Figure 3 , Figure 4 The smoothing mechanism 1 includes a smoothing plate 103, a housing 101, and a push spring 105. A main plate 108 is fixedly installed at the middle position of the upper end face of the smoothing plate 103. Multiple rollers 102 are rotatably installed inside the smoothing plate 103. Side plates 107 are fixedly installed on both sides of the upper end face of the smoothing plate 103. Side grooves 104 are opened on both sides of the inner top surface of the housing 101. The two side plates 107 are slidably installed on the inner walls of the two side grooves 104 respectively. A buffer groove 106 is opened at the middle position of the inner top surface of the housing 101. The main plate 108 is slidably installed on the inner wall of the buffer groove 106. The push spring 105 is fixedly installed between the main plate 108 and the buffer groove 106.

[0028] Specifically, after the glue is applied to the box, it enters the box body 101. The flip-top on the box is pressed down by the flat plate 103. The front of the flat plate 103 is raised, and the pull of the flat plate 103 flattens the flip-top on the box. Rollers 102 are set below the flat plate 103. When the box comes into contact with the rollers 102, the rollers 102 will rotate. The rollers 102 can reduce the friction between the box and the flat plate 103 and prevent the box from getting stuck inside the box body 101. A main plate 108 is set above the flat plate 103. The main plate 108 is pushed by the push spring 105 to press the box, so that the glue on the box adheres better. The compression of the push spring 105 can press boxes of different heights. In addition, side blocks are set on both sides of the flat plate 103 to make the flat plate 103 more stable when moving.

[0029] Working principle: When sealing the box, the box is placed on the conveyor belt 7. The started conveyor belt 7 will drive the box backward. The started small motor 5 will drive the lead screw 3 to rotate. The rotating lead screw 3 will drive the slide cylinder 10 to slide on the slide rod 12 through the threaded block 14, thereby driving the glue spray head 4 to move back and forth. The started micro motor 2 drives the adjusting block 11 to rotate on the inner wall of the vertical block 13, thereby adjusting the angle of the glue spray head 4. The glue spray head 4 sprays glue onto the box. Moreover, there are glue spray heads 4 on both sides of the conveyor belt 7. The two glue spray heads 4 can spray separately. The box is continuously conveyed by the conveyor belt 7 to the smoothing mechanism 1.

[0030] Secondly, a buffer spring is installed inside the smoothing mechanism 1. When the box enters the box body 101, the smoothing plate 103 will press on the box. Rollers 102 are installed inside the smoothing mechanism. The smoothing plate 103 is pushed and pressed on the box by the push spring 105, so that the adhesive sprayed on the box has a better adhesion effect.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
