[0032] Left and right position adjustment: when the box to be packaged is conveyed to the preset initial position of packing table 1, according to the length size of the box, the driving part of translation slide rail 31 is started to drive lifting slide rail 32 to move left and right along translation slide rail 31, and then through feed slide rail 33, top arm 34 to clamping jaw 36, so that clamping jaw 36 moves to the clamping position matched with the left and right directions of the box, to ensure that the box can be clamped centrally.

[0039] More specifically, the guide structure 5 realizes stable guiding and self-adaptive fitting of the high-temperature-resistant adhesive tape, effectively avoids problems such as jamming, deviation, or not tight fitting of the adhesive tape, and provides reliable adhesive tape guiding protection for efficient operation of the entire automatic carton sealing and packaging machine.

[0040] The tape roll is installed: the operator first unscrews the screw cap 52 from the threaded end of the sleeve shaft 51, aligns the inner hole of the high-temperature-resistant tape roll (such as a Teflon tape roll) with the outer sidewall of the sleeve shaft 51, and sleeves the tape roll on the outer sidewall of the sleeve shaft 51; after the tape roll is sleeved in place, the screw cap 52 is re-screwed on the threaded end of the sleeve shaft 51, and the screw cap 52 is rotated clockwise until it tightly fits the end face of the tape roll, realizing axial positioning of the tape roll and preventing the tape roll from moving left and right during the discharging process.

[0041] The tape guide path is debugged: the tape discharge end is led out from the tape roll on the sleeve shaft 51, first passes around the upper wall of the first guide roller 53, changes the conveying direction of the tape (from "horizontal left discharging" to "right upward inclined conveying") through the first guide roller 53; then continues to pull the tape discharge end, passes around the upper wall of the second guide roller 56, and in this process, ensures that the back adhesive surface of the tape faces upward, and the whole tape is attached to the outer circumferential wall of the first guide roller 53 and the second guide roller 56, completing the construction of the tape guide path, at this time the tape is in a state of being ready to be attached.

[0042] When the turnover structure 3 drives the box to be packaged to move along the upper surface of the packaging table 1 from left to right and enter the area with the slot 7, the guide structure 5 starts the attachment action, and the specific process is as follows:

[0043] Initial contact and stress: the lower wall of the box first contacts the back adhesive surface of the tape on the upper wall of the second guide roller 56, and as the box continues to move to the right, the box exerts downward pressure on the second guide roller 56, forcing the second guide roller 56 to drive the second roller frame 54 to turn downward around the hinge point of the second roller frame 54 and the first roller frame 50;

[0044] Elastic structure linkage: when the second roller frame 54 turns downward, the middle bearing 9 drives the corresponding turnover seat 57 to rotate synchronously, which generates an axial thrust on the telescopic rod 58, causing the telescopic rod 58 to shrink in the axial direction in the turnover seat 57 on the side of the second roller frame 54, and at the same time compressing the spring 59 sleeved on the outside of the telescopic rod 58; in this process, the turnover seat 57 on the side of the mounting rod 55 remains fixed with the mounting rod 55, and the bearing 9 adapts to the angle change of the telescopic rod 58, ensuring smooth linkage of the whole elastic structure without jamming;

[0045] Tight attachment guarantee: the spring 59 generates a reverse elastic force during compression, which is transmitted to the second guide roller 56 through the turnover seat 57 and the second roller frame 54, so that the second guide roller 56 is always tightly attached to the lower wall of the box. Even if there is a small protrusion or unevenness on the surface of the box, the second guide roller 56 can also adaptively adjust the height under the action of the spring 59, ensuring that the tape is tightly attached to the lower wall of the box without gaps, and avoiding the problems of air bubbles or poor attachment;

[0046] The adhesive tape continuously discharges: as the box moves, the adhesive tape continuously discharges from the sleeve shaft 51 under the traction of the second guide roller 56, is guided by the first guide roller 53, and continuously adheres to the lower wall of the box through the second guide roller 56, realizing continuous adhesive tape adhesion of the box packaging surface.

[0047] Reset and continuous operation: when a single box completes packaging and leaves the area of the second guide roller 56, the downward pressure on the second guide roller 56 disappears, the spring 59 in the compressed state releases the elastic force to push the reverse seat 57 on the side of the second roller frame 54 to move reversely, so that the telescopic rod 58 extends to reset, and at the same time drives the second roller frame 54 and the second guide roller 56 to flip upward around the hinge point to restore to the initial height (the upper wall of the second guide roller 58 is higher than the packaging table 1); the adhesive tape roll on the sleeve shaft 51 stops discharging under the action of inertia, waits for the next box to enter the packaging area, and repeats the above adhesion process to realize continuous automatic packaging operation of the equipment.

[0048] As shown in FIGS. 4, Figure 5 and Figure 6 As a preferred solution, the cutting structure 6 includes a cylinder frame 61, a second hydraulic cylinder 62, a rotating frame 63, a rotating arm 64, a gear 65, an electric push rod 66, a rack 67, and a cutter 68; one end of the cylinder frame 61 is fixedly arranged on the lower wall of the rear end of the packaging table 1, the second hydraulic cylinder 62 is fixedly arranged on the cylinder frame 61, and the second hydraulic cylinder 62 is located on the rear side of the packaging table 1, the rotating frame 63 is fixedly arranged on the telescopic end of the second hydraulic cylinder 62, the rotating frame 63 is concave, the rotating arm 64 is L-shaped, one end of the rotating arm 64 is movably arranged in the rotating frame 63 through a pin shaft, the pin shaft movably penetrates the rotating frame 63, the gear 65 is fixedly arranged on the pin shaft of the rotating arm 64, the electric push rod 66 is fixedly arranged on one end of the rotating frame 63 on the left side, the rack 67 is fixedly arranged on the telescopic end of the electric push rod 66, and the rack 67 is engaged with the gear 65, and one end of the cutter 68 is fixedly arranged on the other end of the rotating arm 64; the cylinder frame 61 supports the second hydraulic cylinder 62, the second hydraulic cylinder 62 drives the rotating frame 63 to rise or fall, that is, the cutter 68 flips up or falls to cut, the electric push rod 66 drives the rack 67 to move up and down through telescopic movement, so as to drive the cutter 68 to flip by force, the cutter 68 can be vertically located on the rear side of the packaging table 1, and the cutter 68 can be in parallel contact with the packaging table 1, which is used for cutting mode adjustment, the cutter 68 is located between the belt groove 7 and the lifting groove, which is used for cutting position design requirement, realizes that the adhesive tape remains on the second guide roller 56, and is conducive to continuous packaging.

[0049] Initial standby state: when the device does not start the packaging operation or the box does not complete the current face packaging, the cutting structure 6 is in standby state: at this time, the extension end of the second hydraulic cylinder 62 is in the retracted state, driving the whole rotating frame 63 and associated components to drop to the low position, avoiding interference with the box movement; the extension end of the electric push rod 66 is in the extended state, driving the rack 67 to rise, the rack 67 drives the gear 65 to rotate clockwise, and then drives the rotating arm 64 to rotate around the pin shaft, so that the cutter 68 is vertically located at the rear side of the packaging table 1, the cutting edge does not contact the adhesive tape and the box, ensuring that the box can be smoothly moved along the packaging table 1 to the packaging position.

[0050] When the box completes the packaging of the preset face and the length of the adhesive tape reaches the requirement (such as the box packaging face completely covers the adhesive tape), the cutting structure 6 starts the cutting preparation action:

[0051] Height adjustment: according to the height of the box and the position of the adhesive tape in the tape groove 7, the extension end of the second hydraulic cylinder 62 is controlled to extend, driving the rotating frame 63, the rotating arm 64, the cutter 68 and other components to rise synchronously, until the height of the cutting edge of the cutter 68 is adapted to the bonding height of the adhesive tape (the cutting edge is slightly higher than the surface of the adhesive tape by 1-2 mm, to avoid early contact with the adhesive tape causing deviation), completing the height positioning;

[0052] Cutter posture flip: start the electric push rod 66, control its extension end to retract, driving the rack 67 to descend along the vertical direction; during the descending process of the rack 67, the rack 67 is engaged with the gear 65 to drive the gear 65 to rotate counterclockwise, and the gear 65 drives the rotating arm 64 to rotate synchronously through the pin shaft, so that the originally vertical cutter 68 gradually flips to the horizontal direction; continue to control the electric push rod 66 to retract, until the cutting edge of the cutter 68 is completely parallel to the surface of the adhesive tape on the packaging table 1, at this time the cutter 68 is in the cutting-off state.

[0053] After the cutter 68 completes the posture and height adjustment, the cutting-off action is started, according to the toughness characteristics of the high-temperature resistant adhesive tape, two cutting-off modes can be selected to ensure that the cutting-off is complete and the fracture surface is smooth:

[0054] Static cutting-off mode: if the adhesive tape is in a relatively static state after bonding (such as the box is temporarily stopped moving), the extension end of the second hydraulic cylinder 62 is controlled to continue to extend slightly, driving the cutter 68 to descend slightly along the vertical direction, the cutting edge applies vertical pressure to the adhesive tape, and the high-strength cutting edge of the cutter cuts off the high-temperature resistant adhesive tape with strong toughness, and during the cutting-off process, the gear 65 and the rack 67 remain in the engaged state to ensure the stability of the posture of the cutter 68.

[0055] Dynamic cutting mode: if the box needs to move continuously (such as continuous packaging), control the electric push rod 66 to keep the cutter 68 horizontal, and control the extension end of the second hydraulic cylinder 62 to extend slowly, so that the cutter 68 moves slightly in the direction of the box movement while being horizontally attached to the tape, and the blade cuts the tape by "continuous attachment and slow pressure", avoiding the stretching and deformation of the tape caused by the movement of the box or incomplete cutting.

[0056] After the tape is cut off, the pressure cutting structure 6 is immediately reset for the next cutting:

[0057] Cutter posture reset: control the extension end of the electric push rod 66 to extend, drive the rack 67 to rise, drive the gear 65 to rotate clockwise, and make the cutter 68 return to the standby posture of being vertically located at the rear side of the packaging table 1.

[0058] Height reset: control the extension end of the second hydraulic cylinder 62 to retract, drive the turret 63 and associated components to descend to the initial low position, avoiding interference with the movement and packaging of the next box;

[0059] Continuous operation guarantee: since the cutter 68 is located between the tape groove 7 and the lifting port 8, the remaining part of the tape after cutting is still attached to the second guide roller 56 of the guide structure 5, and there is no need to re-pull the tape to enter the next packaging process, effectively reducing the downtime of the equipment and improving the continuous packaging efficiency.

[0060] Working principle:

[0061] First, complete the installation and guide path debugging of the high-temperature resistant tape, and the operator rotates the top plate 52 from the sleeve shaft 51 of the guide structure 5, puts the high-temperature resistant tape roll (such as Teflon tape) on the sleeve shaft 51, and then rotates the top plate 52 back to the sleeve shaft 51 through the thread to limit the tape;

[0062] Then pull the tape feeding end, pass through the upper wall of the first guide roller 53 and the upper wall of the second guide roller 56 in sequence to ensure that the tape back is upward, and when passing through the tape groove 7, the tape guide path is completed, the tape on the upper wall of the first guide roller 53 is inclined to the right to the upper wall of the second guide roller 56, that is, the box can only contact the tape when it moves to the position of the second guide roller 56; the second guide roller 56 keeps the upper wall higher than the surface of the packaging table 1 due to the support of the spring 59, and waits for contact with the box;

[0063] The box is packaged, the opening side is contacted with the packaging table 1 or the box is firstly packaged by the common plastic; after the box is conveyed to the packaging table 1, a pair of overturning structures 3 are started to cooperate with positioning, the lifting slide rail 32 is driven by the translation slide rail 31 to move along the left-right direction to adjust the left-right position of the clamping jaw 36; the feeding slide rail 33 is driven by the lifting slide rail 32 to ascend along the vertical direction to adapt to the height of the box; the L-shaped top arm 34 is driven by the feeding slide rail 33 to move forward and backward, so that the clamping jaw 36 is respectively attached to the right end front side wall and the right side wall of the box to clamp; through the above multi-dimensional adjustment, the clamping jaw 36 completes the center clamping of the box, and it is ensured that the box is aligned with the packaging path in the subsequent movement.

[0064] The box is driven by the overturning structure 3 to move rightwards along the surface of the packaging table 1, when the lower wall of the box contacts the adhesive surface of the adhesive tape on the second guide roller 56, the box continues to move and applies downward pressure to the second guide roller 56; after the second guide roller 56 is stressed, the second roller frame 54 is driven to rotate downward around the connecting point with the first roller frame 50, at the same time, the overturning seat 57 on the second roller frame 54 moves along the telescopic rod 58, the telescopic rod 58 is stressed to overturn by means of the overturning seats 57 at both ends and the bearing 9, and the spring 59 is compressed in the overturning and moving process, the reverse elastic force of the spring 59 ensures that the second guide roller 56 is closely attached to the lower wall of the box, so that the adhesive tape is uniformly attached to the middle part of the box; in this process, the movement of the box synchronously draws the adhesive tape from the sleeve shaft 51, the adhesive tape continuously adheres to the box after being guided by the first guide roller 53, and single-side packaging is completed;

[0065] After packaging, the box moves to the right side of the second guide roller 56, then the cutting structure 6 can be started to cut, and after cutting, the box is conveyed rightwards by the conveying belt body 42 in the conveying unit 4.

[0066] If the box needs to be wrapped and packaged on multiple sides, after the lower wall of the box is packaged, the box moves to the left end above the lifting groove, at this time, a pair of first hydraulic cylinders 41 of the conveying unit 4 are started to drive the conveying belt body 42 to move downwards along the lifting opening 8, the lifting opening 8 is opened to avoid interference with the box overturning; then the damping motor body 35 of the overturning structure 3 drives the clamping jaw 36 to rotate, the clamping jaw 36 drives the box to overturn synchronously to a preset angle (such as 90 degrees or 180), so that the un-packaged side of the box faces the adhesive tape on the second guide roller 56; after overturning is completed, the adhesive tape is adhered and wrapped by overturning, the first hydraulic cylinder 41 is stretched to drive the conveying belt body 42 to rise and reset, the box is moved by the overturning structure 3, the left end of the conveying belt body 42 is on the left end, and the cutting structure 6 is waited to cut the adhesive tape.

[0067] The tape cutting: when the box packaging length reaches the preset value, the pressure cutting structure 6 starts the cutting action: the second hydraulic cylinder 62 drives the rotating frame 63 to rise and fall in the vertical direction, and adjusts to the position matched with the height of the tape; the electric push rod 66 extends and retracts to drive the rack 67 to descend, the rack 67 meshes with the gear 65 to drive the gear 65 to rotate the rotating arm 64 around the pin shaft in the rotating frame 63, the cutter 68 rotates with the rotating arm 64 from the standby posture of "vertically located behind the packaging table 1" to the cutting posture of "parallel to the packaging table 1", at this time, in the process of the cutter 68 rotating, the second hydraulic cylinder 62 is driven to complete the rotating and shearing action of the cutter 68, the cutting edge acts on the high-temperature-resistant tape to complete the cutting; after cutting, the cutter 68 is driven to reset and separate from the packaging table 1 area to prevent shielding the box;

[0068] When the cutter 68 is rotated to the horizontal state of the packaging table 1 supported by the supporting leg 2, the second hydraulic cylinder 62 can directly move the cutter 68 from above the tape to realize the flat direct pressure cutting.

[0069] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit it, and other modifications or functional replacements of the technical solutions of the present application made by those skilled in the art should be covered in the scope of the claims of the present application, as long as they do not deviate from the spirit and scope of the technical solutions of the present application.
