[0030] like Figures 1 to 6 As shown, this utility model provides an automatic wrapping and sealing device for packaging boxes, including a conveyor belt 1. A cover 2 is installed above the frame of the conveyor belt 1. A wrapping mechanism 3 is installed in the middle of the bottom of the inner cavity of the cover 2. An electric push rod 4 is installed in the middle of the wrapping mechanism 3. A base plate 5 is installed at the bottom end of the output rod of the electric push rod 4. A pair of limiting plates 6 and a pressure rod 7 are installed below the base plate 5. A first pressure plate 8 is installed at the bottom end of the pressure rod 7. A second pressure plate 9 is provided below the base plate 5. Four guide rods 10 arranged in a rectangular array are installed on the top of the second pressure plate 9. The top end of each guide rod 10 penetrates the base plate 5 and is equipped with a stop block 11. A spring 12 is sleeved on the outside of each guide rod 10. The spring 12 is located between the base plate 5 and the second pressure plate 9 and is always in a compressed state.
[0031] The second pressure plate 9 has a rectangular through hole. A horizontal plate 13 is installed between the left and right inner walls of the rectangular through hole at a position towards the rear. A first guide roller 14 and a second guide roller 15 are also rotatably installed between the left and right inner walls of the rectangular through hole. The first guide roller 14 is located above the front of the horizontal plate 13, and the second guide roller 15 is located behind the horizontal plate 13. The first pressure plate 8 is located above the second pressure plate 9. The first pressure plate 8 can pass through the rectangular through hole on the second pressure plate 9 and pass in front of the horizontal plate 13. The distance from the bottom of the limiting plate 6 to the upper surface of the second pressure plate 9 is equal to the distance from the lower surface of the first pressure plate 8 to the lower surface of the second pressure plate 9. When the electric push rod 4 controls the bottom plate 5 to move down, the second pressure plate 9 will first contact the packaging box, and then the spring 12 will start to deform. The first pressure plate 8 will continue to move down and pass through the rectangular through hole on the second pressure plate 9 until it contacts the packaging box. At this time, the bottom of the limiting plate 6 will also contact the upper surface of the second pressure plate 9. The first pressure plate 8 and the second pressure plate 9 will press on the packaging box as a whole.
[0032] Two brackets 16 are mounted on the top of the second pressure plate 9. Both brackets 16 are located on the right rear side of the rectangular through hole and are arranged front to back. A motor 18 is mounted on each bracket 16. The motors 18 are servo motors. A drive roller 17 is mounted on the output shaft of each motor 18. A feed cylinder 19 and a winding cylinder 20 are respectively mounted on the front and rear drive rollers 17. A label roll 22 is wound on the feed cylinder 19. The outer end of the label roll 22 first passes under the first guide roller 14, then passes in front of the horizontal plate 13, and finally passes behind the second guide roller 15. After bypassing the label roll 22, the outer end is finally fixed to the roll 20 with glue. The motor 18 can drive the feed cylinder 19 on the two drive rollers 17 and the roll 20 to rotate synchronously. Then the feed cylinder 19 starts to release the label roll 22, and the roll 20 starts to wind up the label roll 22. The inner side of the label roll 22 is provided with multiple labels distributed at equal intervals. When the label roll 22 passes the front side of the horizontal plate 13, the labels on the label roll 22 will separate from it and come to the bottom of the first pressure plate 8. Then the first pressure plate 8 moves down to contact the packaging box, and the label can be affixed to the packaging box.
[0033] The drive roller 17 includes a first baffle 171, a roller shaft 172, a second baffle 173, and bolts 174. The roller shaft 172 is mounted on the output shaft of the motor 18. The first baffle 171 is fixedly mounted on one end of the roller shaft 172 near the motor 18. The second baffle 173 is mounted on the other end of the roller shaft 172 by bolts 174. An axial limiting groove 175 is opened on the outer side of the roller shaft 172.
[0034] The feeding cylinder 19 can be sleeved on the outside of the roller shaft 172. An axial strip-shaped limiting protrusion 21 is provided on the inner side of the feeding cylinder 19. The strip-shaped limiting protrusion 21 can be inserted into the limiting groove 175. When installing the feeding cylinder 19 on the drive roller 17, first remove the bolt 174 and the second baffle 173 from the roller shaft 172. Then, insert the feeding cylinder 19 onto the roller shaft 172 and insert the strip-shaped limiting protrusion 21 into the limiting groove 175. Then, the second baffle 173 and... Bolt 174 can be installed back onto roller shaft 172. After the feeding cylinder 19 is installed, the first baffle 171 and the second baffle 173 will block both ends of the feeding cylinder 19 to prevent it from falling off. When the strip-shaped limiting protrusion 21 is inserted into the limiting groove 175, the feeding cylinder 19 can rotate together with roller shaft 172. The shape and size of the feeding cylinder 19 are the same as those of the winding cylinder 20. The installation method of the winding cylinder 20 is the same as that of the feeding cylinder 19.
[0035] The cover 2 has an inspection port on its left side, and an inspection door 23 is rotatably installed at the inspection port. The inspection port makes it convenient for workers to inspect the inside of the device, and also makes it convenient for workers to replace the tape on the winding mechanism 3, as well as the label rolls 22 on the feed cylinder 19 and the roll cylinder 20.
[0036] Working principle and usage process of this utility model:
[0037] When using the automatic wrapping and sealing device for packaging boxes, the packaging box is first placed between the limiting tracks of the conveyor belt 1. The packaging box automatically stops when it reaches directly below the second pressure plate 9. Then, the two motors 18 start and control the label roll 22 to rotate, so that one of the labels on it comes to the bottom of the first pressure plate 8. Then, the electric push rod 4 starts and controls the bottom plate 5 to move down. The second pressure plate 9 first contacts the packaging box, and then the spring 12 begins to deform. The first pressure plate 8 continues to move down and passes through the rectangular through hole on the second pressure plate 9, affixing the label to the packaging box. At the same time, the first pressure plate 8 and the second pressure plate 9 cooperate to press the lid and body of the packaging box tightly together. Then, the wrapping mechanism 3 starts and wraps multiple turns of tape between the lid and the body. After the wrapping is completed, the electric push rod 4 controls the bottom plate 5 to return to its original position, and the conveyor belt 1 sends out the wrapped packaging box.
[0038] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
