Connecting rods are rotatably installed on one side of the slide plate and the entrance end of the side frame through a rotating shaft, and the other ends of the two connecting rods are rotatably installed with a rotating shaft seat.

[0009] Furthermore, the steering assembly also includes a sliding sleeve, a plug rod is slidably inserted at the center of the rotating shaft seat, and a sliding sleeve is fixed on the top of the plug rod, and the sliding sleeve is slidably connected to both sides of the upper plate.

[0015] Beneficial effects of the present invention:

[0016] 1. The side tapes of the tape assembly of the present invention can be used according to the size of the packaging box. For example, for a packaging box with a smaller width, the spacing between the two upper movable plates and the lower movable plate can only meet the leakage of the middle tape. The stability can be maintained by sticking the middle tape along the top, bottom and both sides. When the packaging box rotates, the width will increase. At this time, the spacing between the upper movable plate and the lower movable plate changes. When it exceeds the maximum distance between the side tapes and the middle tape, the side tapes will be pulled out of the storage groove. At this time, the distance between the two side tapes and the middle tape is the same. By sticking the three tape positions to the longer packaging box surface, the firmness of the sticking can be increased.

[0017] 2. According to the present invention, after the four corners of the packaging box are respectively connected with the upper movable plate, the upper plug plate, the lower movable plate and the lower fixed plate, one end of the tape is pasted on the surface of the packaging box, and then the packaging box is pushed forward to move, the limiting assembly moves along the side frame and the guide plate, the tape assembly moves synchronously, and continuously unwinds to paste the tape on the top and bottom of the packaging box. After the packaging box is completely sent into the limiting assembly, the third electric push rod and the fourth electric push rod respectively drive the upper movable plate to move downward and the lower movable plate to move upward, and the two groups of tapes are gathered on the front end surface of the packaging box for bonding and fixing. At this time, after the method is completed, the upper movable plate and the lower movable plate are reset, and the packaging box is rotated through the steering assembly and then the packaging box is cross-pasted in different directions in the same way.

[0018] 3. In the present invention, the upper movable plate is squeezed by the packaging box to slide along the side frame, and the sliding plate compresses the second spring. Because the sliding plate and the inner wall of the side frame are connected to the rotating shaft seat by a connecting rod, the rotating shaft seat is equivalent to the middle position of the upper movable plate and the upper plug plate. The upper plate is connected to the rotating shaft seat by the plug rod. When the rotating shaft seat produces a lateral translation, it represents that the midpoint position of the upper movable plate and the upper plug plate changes. At this time, the vertical plate drives the upper plate and the lower plate to slide along the side of the base together, keeping the upper pressure plate and the lower pressure plate always corresponding to the center position of the packaging box. In this way, when the motor drives the upper pressure plate to rotate, the rotation path of the packaging box will be the center of the circle at the center point position and will not be offset. In addition, during the pasting process, the second electric push rods outside and inside the vertical plate push the upper plate and the lower plate away from the packaging box, thereby facilitating the movement of the tape assembly and avoiding movement interference.

[0019] 4. The side frame of the present invention slides up and down and left and right along the base through the sliding rod and the sliding groove, and the guide plate is slidably inserted on the inner surface of the base and can slide left and right along the base. In order to carry the packaging box, the lower end of the limit assembly does not need to change its position, and the upper end is adjusted according to the height of the packaging box. The sliding rod and the first spring are slidably sleeved to make the upper movable plate and the upper plug-in plate slide and buckle at the four corners of the top of the packaging box, and the left and right movement of the side frame and the guide plate drives the movement of the connecting frame and the sliding rod through the first electric push rod, which can be adjusted according to the width of the packaging box to meet the placement of packaging boxes of different widths. This process can also adjust the pasting range of the tape assembly, and the distance between the upper and lower limit assemblies can automatically adjust the positions of the upper and lower groups of the tape assembly to keep them parallel to the top and bottom of the packaging box for bonding.

[0020] 5. Compared with the prior art, the present invention places the packaging box inside the limiting component, adjusts the position of each structural member according to the length, width and height of the packaging box, and keeps the steering component corresponding to the center point of the packaging box. While pushing the packaging box, the tape component sticks and seals the packaging box, and automatically adjusts the sticking position according to the width of the packaging box to keep the spacing uniform, thereby improving the packaging efficiency.

The extended ends of the second electric push rod 37 are respectively fixedly connected to the upper plate 33 and the lower plate 34. A motor 35 is fixed at the position of the top of the upper plate 33 corresponding to the upper pressure plate 31, and the output end of the motor 35 is fixedly connected to the upper pressure plate 31 , the upper movable plate 29 is squeezed by the packaging box 4 and slides along the side frame 21, and the slide plate 28 compresses the second spring 210. Because the slide plate 28 and the inner wall of the side frame 21 are connected to the shaft seat 216 through the connecting rod 217, the shaft seat 216 is equivalent to the middle position of the upper movable plate 29 and the upper plug plate 27. The upper plate 33 is connected to the shaft seat 216 through the plug rod 215. When the shaft seat 216 produces a lateral translation, it represents that the midpoint position of the upper movable plate 29 and the upper plug plate 27 changes. At this time, the vertical plate 36 The upper plate 33 and the lower plate 34 are driven to slide along the side of the base 1, and the upper pressure plate 31 and the lower pressure plate 32 are kept corresponding to the center position of the packaging box 4 at all times.

[0034] In this embodiment, the tape assembly 5 also includes a third electric push rod 53, the third electric push rod 53 is fixed on the surface of the slide plate 28, and the extended end of the third electric push rod 53 is fixedly connected to the upper movable plate 29, the upper movable plate 29 and the lower movable plate 213 are both provided with a storage groove 55 on the side facing the middle tape 51, and the side tape 52 is stored in the storage groove 55, the lower movable plate 213 is provided with a sliding frame 212 on the side facing the guide plate 211, and the sliding frame 212 is slidably sleeved on the guide plate 211, and a fourth electric push rod 54 is fixed on the surface of the sliding frame 212, and the extended end of the fourth electric push rod 54 is fixedly connected to the lower movable plate 2 13 is fixedly connected, and the two sides of the side tape 52 are fixedly connected with telescopic rods 56, and the other ends of the telescopic rods 56 slide along the inside of the storage groove 55 and are fixed to one end of the middle tape 51. The side tape 52 of the tape assembly 5 can be used according to the size of the packaging box 4. For example, for a packaging box 4 with a smaller width, the spacing between the two upper movable plates 29 and the lower movable plate 213 can only meet the leakage of the middle tape 51. It only needs to stick the middle tape 51 along the top and bottom and both sides to maintain stability. When the packaging box 4 rotates, the width will increase. At this time, the spacing between the upper movable plate 29 and the lower movable plate 213 changes, exceeding the side When the adhesive tape 52 is at the maximum distance from the middle adhesive tape 51, the side adhesive tape 52 will be pulled out from the storage groove 55. At this time, the distance between the two side adhesive tapes 52 and the middle adhesive tape 51 is the same. The longer surface of the packaging box 4 is pasted through the three adhesive tape positions. The telescopic rod 56 at the other end of the side adhesive tape 52 slides along the inside of the storage groove 55, which is a common structure in which a moving block slides along the groove. Whether the side adhesive tape 52 extends out is determined according to the width of the packaging box 4 when the packaging box 4 is placed at the beginning. After the four corners of the packaging box 4 are respectively connected with the upper moving plate 29, the upper plug plate 27, the lower moving plate 213 and the lower fixed plate, one end of the adhesive tape is pasted on the surface of the packaging box 4, and then After that, the packaging box 4 is pushed forward to move, the limiting component 2 moves along the side frame 21 and the guide plate 211, the tape component 5 moves synchronously, and continuously unwinds the tape to stick it on the top and bottom of the packaging box 4. After the packaging box 4 is completely sent into the limiting component 2, the third electric push rod 53 and the fourth electric push rod 54 respectively drive the upper movable plate 29 to move downward and the lower movable plate 213 to move upward, and the two groups of tapes are gathered on the front end surface of the packaging box 4 for bonding and fixing.

One end of the adhesive tape is pasted on the surface of the packaging box 4, and then the packaging box 4 is pushed forward to move. The limit assembly 2 moves along the side frame 21 and the guide plate 211, and the adhesive tape assembly 5 moves synchronously and continues to unwind to paste the adhesive tape on the top and bottom of the packaging box 4. After the packaging box 4 is completely sent into the limit assembly 2, the third electric push rod 53 and the fourth electric push rod 5 4 drives the upper movable plate 29 downward and the lower movable plate 213 upward respectively, and the two sets of adhesive tapes are gathered on the front end surface of the packaging box 4 for bonding and fixing. At this time, after the method is completed, the upper movable plate 29 and the lower movable plate 213 are reset, and the packaging box 4 is rotated by the steering assembly 3 and then the packaging box 4 is cross-pasted in different directions in the same way. The upper movable plate 29 is squeezed by the packaging box 4 and slides along the side frame 21. The slide plate 28 compresses the second spring 210. Because the slide plate 28 and the inner wall of the side frame 21 are connected to the shaft seat 216 through the connecting rod 217, the shaft seat 216 is equivalent to the middle position of the upper movable plate 29 and the upper plug plate 27. The upper plate 33 is inserted through the rod 215 is connected to the shaft seat 216. When the shaft seat 216 produces a lateral translation, it represents that the midpoint position of the upper movable plate 29 and the upper plug plate 27 changes. At this time, the vertical plate 36 drives the upper plate 33 and the lower plate 34 to slide along the side of the base 1, keeping the upper pressure plate 31 and the lower pressure plate 32 always corresponding to the center position of the packaging box 4. In this way, when the motor 35 drives the upper pressure plate 31 to rotate, the rotation path of the packaging box 4 will be the center point position of the circle, and will not be offset. In addition, during the pasting process, the second electric push rod 37 on the outside and inside of the vertical plate 36 pushes the upper plate 33 and the lower plate 34 away from the packaging box 4, thereby facilitating the movement of the tape assembly 5 and avoiding movement interference.
