[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0019] like Figures 1 to 6As shown, the packaging box sealing device of the present invention includes two oppositely arranged side panels 10, one of which is provided with a bearing assembly 11 for installing a tape, and a blade 12 and a contact roller 13 are provided between the two side panels 10; a pressure rod 21 is slidably provided on each side panel 10, and the end of the pressure rod 21 passes through the side panel 10 and is rotatably connected to a pressure block 22, so that the pressure block 22 can rotate horizontally; the pressure block 22 can abut against the side panel 10, and an auxiliary roller 23 is rotatably connected to the pressure block 22, and the axes of the auxiliary roller 23 and the contact roller 13 are parallel to each other.

[0020] When the tape needs to be installed, the pressure rod 21 is pressed to make it slide along the side plate 10, so that the pressure block 22 stops contacting the side plate 10, and then the auxiliary roller 23 and the pressure block 22 are rotated relative to the pressure rod 21, so that the auxiliary roller 23 is adjusted to be perpendicular to the axis of the contact roller 13. At this time, the auxiliary roller 23 avoids the conveying range of the tape, and the end of the tape is pulled out and directly bypasses the contact roller 13. The reverse operation is then performed to adjust the auxiliary roller 23 to be parallel to the axis of the contact roller 13, so that the tape is in a state of passing through between the contact roller 13 and the auxiliary roller 23. It is easy to use and simple to operate.

[0021] The contact roller 13 and the auxiliary roller 23 are preferably made of rubber. Contact rollers 13 are provided at both ends of the side panel 10 to facilitate contact with the carton. The front contact roller 13 is also used to convey the tape. The outer circumferential surface of the contact roller 13 is preferably frosted or provided with an anti-slip layer to increase the friction between the outer circumferential surface of the contact roller 13 and the carton or tape, thereby preventing the contact roller 13 from jamming during rotation. The auxiliary roller 23 is used to prevent the tape from retreating, and anti-sticking grooves are spaced apart on its outer circumference to facilitate tape removal. The specific configuration of the contact roller 13 and the auxiliary roller 23 is conventional and will not be described in detail here.

[0022] Preferably, see Figures 1 to 3 The side plate 10 is provided with a pressing groove 24 corresponding to the pressing block 22 and a receiving groove 25 corresponding to the auxiliary roller 23. The pressing groove 24 is connected to the receiving groove 25, and the side and end faces of the pressing block 22 can abut against the side of the pressing groove 24 away from the auxiliary roller 23.

[0023] When the side surface of the pressing block 22 abuts against the side of the pressing groove 24 away from the auxiliary roller 23, the auxiliary roller 23 is perpendicular to the axis of the contact roller 13. At this time, the auxiliary roller 23 is in the accommodating groove 25 to avoid the conveying range of the tape and prepare for the tape to pass through between the contact roller 13 and the auxiliary roller 23; when the end face of the pressing block 22 abuts against the side of the pressing groove 24 away from the auxiliary roller 23, the auxiliary roller 23 is parallel to the axis of the contact roller 13. At this time, the tape is in a state of passing through between the contact roller 13 and the auxiliary roller 23.

[0024] The distance between the inner sides of the two side panels 10 is greater than the length of the contact roller 13 and the width of the tape, meaning there is a certain distance between the edge of the tape and the side panels 10. The horizontal width and vertical height of the accommodating groove 25 are both greater than the diameter of the auxiliary roller 23. The length of the accommodating groove 25 is greater than the length of the auxiliary roller 23. When the auxiliary roller 23 is within the accommodating groove 25, it can avoid the conveying range of the tape.

[0025] Preferably, the end of the pressure block 22 close to the auxiliary roller 23 is rotatably connected to the auxiliary roller 23 through a bearing 26, and a through groove 27 is provided at the end of the pressure block 22 away from the auxiliary roller 23, and the end of the pressure rod 21 close to the auxiliary roller 23 is rotatably set in the through groove 27.

[0026] When the pressing block 22 is rotatably connected to the pressing rod 21 , the pressing block 22 can abut against the side plate 10 , and the parts are arranged more compactly, thereby avoiding movement interference.

[0027] The pressing block 22 is formed into a U-shaped block by providing a through slot 27, and the pressing rod 21 is rotatably inserted into the opening of the U-shaped block. The facing surface of the U-shaped block opening is the end face of the pressing block 22, and the side surface of the U-shaped block opening is the side surface of the pressing block 22.

[0028] Preferably, a spring 28 is mounted on the pressure rod 21, and the spring 28 is a compression spring, so that the pressure block 22 always has a tendency to abut against the side plate 10. A pressing head 29 is provided at one end of the pressure rod 21 away from the auxiliary roller 23, and one end of the spring 28 is connected to the pressing head 29, and the other end is connected to the side plate 10.

[0029] Among them, the part of the pressure rod 21 that slides along the side plate 10 is a square axis. Correspondingly, a square hole is opened on the side plate 10, and the square hole is correspondingly connected to the pressure groove 24, so that the pressure rod 21 can only slide along the side plate 10 and prevent the pressure rod 21 from rotating around its axis.

[0030] Preferably, see Figure 1 、 Figure 4 The blade 12 is rotatably connected to the side plate 10 through an adjusting shaft 31. A connecting block 32 is provided on the side plate 10. A threaded hole is provided on the connecting block 32. A threaded shaft 33 is connected to the threaded hole. One end of the threaded shaft 33 can abut against the outer circumferential surface of the adjusting shaft 31, and the other end is connected to an adjusting knob 34.

[0031] The blade 12 can rotate relative to the side panel 10 and be locked by abutment through the threaded shaft 33 to adjust the orientation angle of the blade 12 to adapt to the usage habits of different users, and the blade 12 can be rotated to retract into the inside of the side panel 10 to avoid causing harm to the user when not in use.

[0032] The ends of the adjustment shaft 31 pass through the side plate 10, and connecting blocks 32 are provided on the outside of the side plate 10 to lock both ends of the adjustment shaft 31, making the installation of the blade 12 more stable. The cross-sections of the ends of the adjustment shaft 31 are preferably polygonal, so that one end of the threaded shaft 33 can stably abut the side of the polygon, further improving the installation stability of the blade 12.

[0033] Preferably, the bearing assembly 11 includes a bearing plate 14 and a bearing tube 15 . The bearing plate 14 is provided on one of the side plates 10 . A through hole is provided on the bearing plate 14 . The bearing tube 15 is horizontally provided on the bearing plate 14 and corresponds to the through hole.

[0034] The carrier tube 15 is used to mount the tape, and a retaining ring is used to prevent the tape from slipping off the carrier tube 15. The retaining ring can be snap-fitted or threadedly connected to the carrier tube 15 for easy assembly and disassembly. The carrier tube 15 can be equipped with multiple bearings, and the tape can be mounted on the outer sides of the bearings to facilitate the rotation and delivery of the tape.

[0035] The working principle of this utility model is as follows:

[0036] When the tape needs to be installed, the pressure rod 21 is pressed to slide along the side plate 10, so that the pressure block 22 is separated from the side plate 10, and then the auxiliary roller 23 and the pressure block 22 are rotated relative to the pressure rod 21, so that the auxiliary roller 23 is adjusted to be perpendicular to the axis of the contact roller 13, and then the pressure rod 21 is released. Under the action of the spring 28, the side surface of the pressure block 22 abuts against the side of the pressure groove 24 away from the auxiliary roller 23. At this time, the auxiliary roller 23 is in the accommodating groove 25 and avoids the conveying range of the tape. Figure 6 As shown, the end of the tape is then pulled out and directly passed over the contact roller 13;

[0037] The above operation is then performed in reverse, that is, the pressure rod 21 is pressed again to slide along the side plate 10, so that the pressure block 22 is separated from the side plate 10, and the auxiliary roller 23 and the pressure block 22 are rotated in the opposite direction relative to the pressure rod 21, so that the axis of the auxiliary roller 23 is parallel to the axis of the contact roller 13, and then the pressure rod 21 is released. Under the action of the spring 28, the end face of the pressure block 22 abuts against the side of the pressure groove 24 away from the auxiliary roller 23. At this time, the adhesive tape is in a state of passing through between the contact roller 13 and the auxiliary roller 23, as shown in FIG. Figure 1 、 Figure 5 As shown, it is easy to use and simple to operate.

[0038] The blade 12 can rotate relative to the side panel 10 and be locked by abutment through the threaded shaft 33 to adjust the orientation angle of the blade 12 to adapt to the usage habits of different users, and the blade 12 can be rotated to retract into the inside of the side panel 10 to avoid causing harm to the user when not in use.
