Description

Technical Field

[0001] This invention relates to the field of tape packaging equipment technology, specifically to a high-temperature resistant tape automatic box sealing and packaging machine. Background Technology

[0002] In the field of tape packaging equipment technology, with the continuous improvement of packaging protection requirements in industries such as electronics, automobiles, and chemicals, high-temperature resistant tape has become the core consumable for box sealing in high-temperature operation scenarios (such as engine component packaging and high-temperature storage of electronic components) due to its ability to maintain good adhesion and structural stability in high-temperature environments. Its application demand is showing a year-on-year growth trend. However, most automatic carton sealing equipment currently on the market is designed based on the physical properties of ordinary tape. When adapting to high-temperature resistant tape for carton sealing, it is difficult to meet the needs of industrial production: First, the carton positioning and flipping mechanism has limitations, and it cannot automatically wrap the packaging along the seal, nor can it flexibly adjust the centering positioning parameters according to different carton sizes. Second, due to the special material of high-temperature resistant tape, such as Teflon tape, it is relatively difficult to cut compared to ordinary tape. Third, the poor coordination of the various functional components of the equipment leads to interruptions in the operation process, significantly reducing the overall carton sealing efficiency. Summary of the Invention

The second guide roller is movably mounted on the other end of the second roller frame and movably passes through the right end of the groove. The upper wall of the second guide roller is located above the packaging table. One end of a pair of flipping seats is movably mounted on the middle of the bearings of the mounting rod and the second roller frame, and the flipping seats can rotate. One end of the telescopic rod is fixedly mounted on one of the flipping seats, and the other end of the telescopic rod movably passes through the other end of the other flipping seat.

[0008] Preferably, the telescopic rod cannot detach from the flip seat, and the telescopic rod can extend and retract within another flip seat.

[0009] Preferably, the cutting structure includes a cylinder frame, a second hydraulic cylinder, a rotating frame, a rotating arm, a gear, an electric push rod, a rack, and a cutter; one end of the cylinder frame is fixedly mounted on the lower rear wall of the packaging table, the second hydraulic cylinder is fixedly mounted on the cylinder frame and located on the rear side of the packaging table, the rotating frame is fixedly mounted on the telescopic end of the second hydraulic cylinder, the rotating frame is concave, the rotating arm is L-shaped, one end of the rotating arm is movably mounted inside the rotating frame via a pin, and the pin movably passes through the rotating frame, the gear is fixedly mounted on the pin of the rotating arm, the electric push rod is fixedly mounted on the left side of one end of the rotating frame, the rack is fixedly mounted on the telescopic end of the electric push rod and meshes with the gear, and one end of the cutter is fixedly mounted on the other end of the rotating arm.

[0010] Preferably, the cutter is positioned vertically behind the packaging table and is in parallel contact with the packaging table.

[0011] Preferably, the cutter is located between the groove and the lifting groove.

[0012] Preferably, the second guide roller is able to flip downwards under force, and the flipping seat on the second roller frame can move on the telescopic rod, causing the telescopic rod to flip at a certain angle, while compressing the spring.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The guide structure, through the combination of a "sleeve shaft and a detachable top plate," enables rapid disassembly, assembly, and positioning of high-temperature resistant tape. It is easy to operate and adaptable to tape rolls of different specifications, solving the problem of cumbersome tape installation in traditional equipment. Simultaneously, the second guide roller, combined with a telescopic rod and spring, forms an elastic adaptation structure. When in contact with the box, it can be flipped downwards and the spring compressed. The spring's rebound maintains consistent pressure on the box, ensuring a tight fit between the tape and the center of the box. This avoids insufficient sealing due to gaps in the fit, and the tape always maintains a preset posture with the adhesive side facing upwards, eliminating the need for manual adjustment and further improving bonding accuracy.

[0014] 2. The flip structure relies on the multi-dimensional adjustment capabilities of the translation slide rail, lifting slide rail, and feed slide rail to precisely adjust the position and height of the gripper, achieving centering positioning of boxes of different sizes, with strong adaptability. At the same time, the flip structure can drive the box to move horizontally to complete single-sided sealing, and after the conveyor unit descends and opens the lifting port, it can drive the box to flip to achieve winding sealing, meeting different sealing requirements such as single-sided and multi-sided sealing, without the need to change equipment or adjust the core structure, greatly improving the equipment's compatibility with diverse sealing scenarios.

[0015] 3. The conveying unit drives the conveyor belt to lift and lower via the first hydraulic cylinder. When the box is flipped and sealed, the conveyor belt lowers and opens the lifting port to avoid interference with the flipping action. After sealing, the conveyor belt immediately rises to be level with the packaging table and automatically conveys the finished box, achieving a seamless connection between the "sealing and conveying" process and reducing manual transfer links. In addition, the tape is fed and pulled synchronously during the movement of the box, eliminating the need for additional power to drive the tape conveyor. This reduces energy consumption and avoids the problem of "tape feeding and box movement not being synchronized", thus improving the overall sealing efficiency.

[0016] 4. The cutting structure supports two states for the cutter: "vertically positioned behind the packaging table (standby)" and "parallel contact with the packaging table (cutting)". Combined with the design of an electric push rod driving a rack and pinion to rotate the cutter and a second hydraulic cylinder adjusting the cutter height, it can select the appropriate cutting method for the tough characteristics of high-temperature resistant tape, ensuring a flat, burr-free, and tensile-deformed cut surface. This solves the problem of incomplete breakage when cutting high-temperature resistant tape in traditional equipment. At the same time, the tape remains on the second guide roller after cutting, eliminating the need for re-threading before entering the next packaging process, reducing preparation time and improving the continuous operation capability of the equipment.

[0017] 5. In the overall structural design, all core components (such as the roller frame of the guide structure and the rotating frame of the cutting structure) adopt a modular fixing method, which facilitates later maintenance and component replacement; and the entire packaging process (positioning, bonding, flipping, cutting and conveying) does not require manual intervention, which reduces labor costs and avoids human operation errors, thereby improving the consistency and stability of packaging quality.

[0020] The following will refer to the appendices in the embodiments of the present invention. Figures 1-7 For further details: like Figure 1 As shown, the present invention provides a technical solution: an automatic high-temperature resistant tape sealing and packaging machine, comprising a packaging platform 1, a pair of support legs 2, a pair of flipping structures 3, a conveying unit 4, a guiding structure 5, and a cutting structure 6; the packaging platform 1 is rectangular, and a groove 7 is provided near the center of the packaging platform 1, with a lifting port 8 on the right side of the groove 7; both support legs 2 are concave, and the support legs 2 are symmetrically arranged on the lower wall of the packaging platform 1, and the support legs 2 are symmetrically arranged near the left and right ends; a pair of flipping structures 3 are symmetrically arranged between the support legs 2, and are located symmetrically on the front and rear sides of the packaging platform 1; the conveying unit 4 is fixedly arranged on one of the support legs 2. The packaging platform 1 is constructed with the following components: the conveying unit 4 is located at the lifting port 8; the guiding structure 5 is fixedly installed on the lower wall of the packaging platform 1 and located at the groove 7; the pressing and cutting structure 6 is fixedly installed on the lower rear wall of the packaging platform 1 and located between the groove 7 and the lifting port 8; the support leg 2 supports the packaging platform 1 at a certain height; the packaging platform 1 carries the guiding structure 5 and the pressing and cutting structure 6; the guiding structure 5 is used to guide the tape; the flipping structure 3 is used to drive the box to be centered, positioned, moved, and flipped; the conveying unit 4 is used to fit the box to flip and open the lifting port 8 and to convey the packaged product; and the pressing and cutting structure 6 is used to cut the high-temperature resistant tape after packaging.

[0021] Such as 2 and Figure 7As shown, in a preferred embodiment, the flipping structure 3 includes a translation slide rail 31, a lifting slide rail 32, a feed slide rail 33, a top arm 34, a damping motor body 35, and a gripper 36. The translation slide rail 31 is fixedly mounted at both ends on the front side of the support leg 2 and is parallel to the packaging table 1. The lifting slide rail 32 is fixedly mounted on the translation slide rail 31 and moves left and right via the translation slide rail 31. The feed slide rail 33 is fixedly mounted on the lifting slide rail 32 and moves up and down via the lifting slide rail 32. The feed slide rail 33 is located above the packaging table 1. The top arm 34 is L-shaped. One end of the top arm 34 is fixedly mounted on the feed slide rail 33, and the top arm 34 moves back and forth through the feed slide rail 33. The damping motor body 35 is fixedly mounted inside the other end of the top arm 34, and the drive end of the damping motor body 35 moves through the side wall of the other end of the top arm 34. The gripper 36 is L-shaped, and one end of the gripper 36 is fixedly mounted on the drive end of the damping motor body 35. The lifting slide rail 32 is moved left and right by the translation slide rail 31, and the feed slide rail 33 is moved up and down by the lifting slide rail 32, thereby adjusting the left and right position and height of the gripper 36. The gripper 36 is rotated by the damping motor body 35.

[0022] Left and right position adjustment: After the box to be packaged is transported to the preset initial position of the packaging table 1, according to the length of the box, the drive component of the translation slide rail 31 is activated to drive the lifting slide rail 32 to move left and right along the translation slide rail 31, and then through the feed slide rail 33 and the top arm 34 to the gripper 36, so that the gripper 36 moves to a clamping position that matches the left and right direction of the box, ensuring that the box can be clamped in the center; Height adjustment: According to the height of the box to be packaged, start the drive component of the lifting slide rail 32, drive the feed slide rail 33 to rise and fall vertically along the lifting slide rail 32, and drive the gripper 36 to rise and fall synchronously through the top arm 34 so that the clamping surface of the gripper 36 matches the height of the side wall of the box, so as to avoid the box tilting due to the clamping position being too high or too low. Front and rear position adjustment: Start the drive component of the feed slide rail 33, drive the top arm 34 to move back and forth along the feed slide rail 33 so that the gripper 36 gradually approaches the box to be packaged, until the two L-shaped clamping surfaces of the gripper 36 are tightly attached to the side wall and end face of the box respectively, completing the centering and stable clamping of the box.

[0023] After the box is positioned and clamped, if single-sided sealing is required, the drive components of the translation slide rail 31 and the feed slide rail 33 can be coordinated to drive the gripper 36 to move smoothly along the upper surface of the packaging table 1. During the movement, the relative position of the box and the packaging table 1 is kept stable to ensure that the tape can accurately adhere to the sealing surface of the box. When multi-sided wrapping sealing of the box is required, after the box is sealed on one side and moved to the preset flipping position, the damping motor body 35 is started. Its drive end drives the gripper 36 to rotate slowly, thereby driving the clamped box to flip synchronously. The damping characteristics of the damping motor body 35 can ensure that the flipping process is smooth and slow, avoiding the shaking of the internal items or the tape falling off due to the box flipping speed being too fast. According to the sealing requirements, the damping motor body 35 can be controlled to achieve different angles such as 90° and 180°, so that the unsealed side of the box faces the tape feeding direction, so as to carry out subsequent sealing operations.

[0024] Reset and continuous operation: After a single box completes all the packaging processes, the damping motor body 35 is controlled to drive the gripper 36 to rotate in the opposite direction to reset. Then, the drive components of the feed slide rail 33, lifting slide rail 32, and translation slide rail 31 are started in sequence to drive the gripper 36 back to the initial standby position, waiting for the next box to be packaged to be transported to the packaging table 1. The above positioning, moving, and flipping process is repeated to realize continuous automated packaging operation.

[0025] As shown in Figure 2, as a preferred embodiment, the conveying unit 4 includes a pair of first hydraulic cylinders 41 and a conveyor belt body 42; the pair of first hydraulic cylinders 41 are symmetrically arranged on the upper wall of one of the support legs 2 and located below the lifting port 8; the conveyor belt body 42 is fixedly arranged between the telescopic ends of the pair of first hydraulic cylinders 41 and is movably embedded in the lifting port 8.

[0026] As shown in Figure 3, in a preferred embodiment, the guiding structure 5 includes a first roller frame 50, a sleeve shaft 51, a top plate 52, a first guide roller 53, a second roller frame 54, a mounting rod 55, a second guide roller 56, a pair of flip seats 57, a telescopic rod 58, and a spring 59. The first roller frame 50 is concave, with one end fixedly mounted on the lower wall of the packaging table 1 and located on the left side of the groove 7. One end of the sleeve shaft 51 movably passes through one end of the first roller frame 50, and the outer side wall of the other end of the sleeve shaft 51 is threaded. The top plate 52 is detachably screwed onto the sleeve shaft 51. The sleeve shaft 51 is used to mount the tape. A guide roller 53 is movably mounted on the other end of the first roller frame 50, and the first guide roller 53 is located below the left end of the groove 7. One end of a second roller frame 54 is movably mounted on the other end of the first roller frame 50, and the other end of the second roller frame 54 is located inside the right end of the groove 7. One end of a mounting rod 55 is fixedly connected to the first roller frame 50 and located below the second roller frame 54. Bearings 9 are provided at the other end of the mounting rod 55 and in the middle of the second roller frame 54. A second guide roller 56 is movably mounted on the other end of the second roller frame 54, and the second guide roller 56 movably passes through the right end of the groove 7. The upper wall of the second guide roller 56 is located... Above the packaging platform 1, a pair of flip seats 57 are respectively movably mounted at one end on the mounting rod 55 and the middle of the bearing 9 of the second roller frame 54, and the flip seats 57 can rotate. One end of the telescopic rod 58 is fixedly mounted on one of the flip seats 57, and the other end of the telescopic rod 58 movably passes through the other end of the other flip seat 57. The telescopic rod 58 cannot detach from the flip seat 57, and the telescopic rod 58 can extend and retract within the other flip seat 57. A spring 59 is movably fitted onto the telescopic rod 58, and both ends of the spring 59 are respectively blocked and limited by the flip seat 57; through the first roller frame 50 The sleeve 51 is fitted with Teflon tape. The top plate 52 is screwed on and tightens the limiting tape. The tape feeding end is pulled and passed through the upper wall of the first guide roller 53 with the adhesive side facing up. Then the tape is passed through the upper wall of the second guide roller 56. When the box moves from the packaging table 1, it comes into contact with the tape. At the same time, the second guide roller 56 is forced to drop and compress the spring 59. The second guide roller 56 can flip downward under force, and the flipping seat 57 on the second roller frame 54 can move on the telescopic rod 58 and drive the telescopic rod 58 to flip at a certain angle. At the same time, the spring 59 is compressed, which is used for the design linkage requirements.

[0027] More specifically, the guide structure 5 enables stable guiding and adaptive bonding of high-temperature resistant tape, effectively avoiding problems such as tape jamming, offset, or loose bonding, and providing reliable tape guiding guarantee for the efficient operation of the entire automatic sealing and packaging machine.

[0028] Tape roll installation: The operator first unscrews the top plate 52 from the threaded end of the sleeve shaft 51, aligns the inner hole of the high-temperature resistant tape roll (such as Teflon tape roll) with the sleeve shaft 51, and fits it onto the outer wall of the sleeve shaft 51; after the tape roll is in place, the top plate 52 is screwed back onto the threaded end of the sleeve shaft 51, and the top plate 52 is rotated clockwise until it fits tightly against the end face of the tape roll, thereby axially limiting the tape roll and preventing the tape roll from moving left and right during the feeding process.

[0029] Belt feeding path debugging: Lead the belt feed end out from the belt roll on the sleeve 51. First, let the belt feed end go around the upper wall of the first guide roller 53. Change the conveying direction of the belt through the first guide roller 53 (so that the belt changes from "horizontal feed to the left" to "slanted conveying to the upper right"). Then continue to pull the belt feed end around the upper wall of the second guide roller 56. During this process, it is necessary to ensure that the adhesive side of the belt is facing up and that the belt is fully attached to the outer circumferential wall of the first guide roller 53 and the second guide roller 56 to complete the belt feeding path construction. At this time, the belt is in the state of waiting to be attached.

[0030] When the flipping structure 3 moves the box to be packaged from left to right along the upper surface of the packaging platform 1 and enters the grooved area 7, the guiding structure 5 initiates the bonding action. The specific process is as follows: Initial contact and force: The lower wall of the box first contacts the adhesive backing of the tape on the upper wall of the second guide roller 56. As the box continues to move to the right, the box applies downward pressure to the second guide roller 56, forcing the second guide roller 56 to drive the second roller frame 54 to flip downward around its hinge point with the first roller frame 50. Elastic structure linkage: When the second roller frame 54 flips downward, the central bearing 9 drives the corresponding flipping seat 57 to rotate synchronously. The flipping seat 57 generates an axial thrust on the telescopic rod 58, causing the telescopic rod 58 to contract axially within the flipping seat 57 on the side of the second roller frame 54, while simultaneously compressing the spring 59 fitted on the outside of the telescopic rod 58. During this process, the flipping 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 entire elastic structure without any jamming. Tight fit guarantee: Spring 59 generates a reverse elastic force during compression. This elastic force is transmitted to the second guide roller 56 through the flip seat 57 and the second roller frame 54, ensuring that the second guide roller 56 is always tightly fitted to the lower wall of the box. Even if there are minor protrusions or unevenness on the surface of the box, the second guide roller 56 can adaptively adjust its height under the action of spring 59 to ensure that the tape is fitted to the lower wall of the box without gaps, avoiding problems such as air bubbles or poor adhesion. Continuous tape feeding: As the box moves, the tape is continuously fed from the sleeve shaft 51 under the traction of the second guide roller 56. After being guided by the first guide roller 53, it is continuously adhered to the lower wall of the box by the second guide roller 56, so as to achieve continuous tape adhesion on the box sealing surface.

[0031] Reset and continuous operation: After a single box is sealed and detached from the area of ​​the second guide roller 56, the downward pressure on the second guide roller 56 disappears. The compressed spring 59 releases its elastic force to push the flipping seat 57 on the side of the second roller frame 54 to move in the opposite direction, causing the telescopic rod 58 to extend and reset. At the same time, it drives the second roller frame 54 and the second guide roller 56 to flip upward around the hinge point and return to the initial height (the upper wall of the second guide roller 58 is higher than the packaging table 1). The tape roll on the sleeve shaft 51 stops feeding under inertia and waits for the next box to enter the sealing area. The above bonding process is repeated to realize the continuous automated sealing operation of the equipment.

[0032] For example, 4. Figure 5 and Figure 6 As shown, as a preferred embodiment, the pressure-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 mounted on the lower rear wall of the packaging table 1. The second hydraulic cylinder 62 is fixedly mounted on the cylinder frame 61 and is located on the rear side of the packaging table 1. The rotating frame 63 is fixedly mounted on the telescopic end of the second hydraulic cylinder 62. The rotating frame 63 is concave, and the rotating arm 64 is L-shaped. One end of the rotating arm 64 is movably mounted inside the rotating frame 63 via a pin, and the pin movably passes through the rotating frame 63. The gear 65 is fixedly mounted on the pin of the rotating arm 64. The electric push rod 66 is fixedly mounted on the left side of one end of the rotating frame 63. The rack 67 is fixedly mounted on the rotating arm 64. The rack 67 is fixedly mounted on the telescopic end of the electric push rod 66, and meshes with the gear 65. One end of the cutter 68 is fixedly mounted on the other end of the rotating arm 64. The second hydraulic cylinder 62 is supported by the cylinder frame 61. The second hydraulic cylinder 62 drives the rotating frame 63 to rise or fall, which matches the cutting blade 68 to flip up or fall to cut. The electric push rod 66 telescopically drives the rack 67 to rise and fall, causing the gear 65 to be forced to flip the cutting blade 68. The cutting blade 68 can be vertically positioned on the rear side of the packaging table 1 and can be parallel to the packaging table 1 for cutting mode adjustment. The cutting blade 68 is located between the groove 7 and the lifting groove to meet the cutting position design requirements, so that the tape is kept on the second guide roller 56, which is beneficial for continuous packaging.

[0033] Initial standby state: When the equipment has not started the packaging operation or the box has not completed the current packaging, the pressure cutting structure 6 is in standby state: At this time, the telescopic end of the second hydraulic cylinder 62 is in the retracted state, which drives the rotating frame 63 and related components to descend to the low position to avoid interfering with the movement of the box; the telescopic end of the electric push rod 66 is in the extended state, which drives the rack 67 to rise. The rack 67 drives the gear 65 to rotate clockwise, which in turn drives the rotating arm 64 to rotate around the pin shaft, so that the cutter 68 is vertically located on the rear side of the packaging table 1, and the blade does not contact the tape or the box, ensuring that the box can move smoothly along the packaging table 1 to the packaging position.

[0034] When the flipping structure 3 completes the sealing of the preset surface of the enclosure and the tape adhesion length reaches the requirement (e.g., the enclosure sealing surface is completely covered by the tape), the cutting structure 6 initiates the cutting preparation action: Height adjustment: Based on the height of the box and the position of the tape in the groove 7, control the extension end of the second hydraulic cylinder 62 to extend, driving the rotating frame 63, rotating arm 64, cutter 68 and other components to rise synchronously until the blade height of the cutter 68 matches the adhesion height of the tape (the blade is slightly higher than the tape surface by 1-2mm to avoid premature contact with the tape and displacement), thus completing the height positioning; Cutter posture flipping: Activate electric push rod 66 to control its telescopic end to retract, driving rack 67 to descend vertically; during the descent of rack 67, it meshes with gear 65, driving gear 65 to rotate counterclockwise, and gear 65 drives rotating arm 64 to flip synchronously through pin shaft, so that the originally vertical cutter 68 gradually flips to the horizontal direction; continue to control electric push rod 66 to retract until the blade of cutter 68 is completely parallel to the tape surface on packaging table 1, at which point cutter 68 is in the ready-to-cut state.

[0035] After the cutter 68 completes its posture and height adjustment, the cutting action is initiated. Based on the toughness characteristics of the high-temperature resistant tape, two cutting modes can be selected to ensure a thorough cut and a smooth cut surface: Static cutting mode: If the tape is in a relatively static state after being applied (such as when the box is not moving), the extension end of the second hydraulic cylinder 62 is controlled to continue to extend slightly, causing the cutter 68 to descend slightly in the vertical direction. The blade applies vertical pressure to the tape, and the high-strength blade of the cutter cuts the tough, high-temperature resistant tape. During the cutting process, the gear 65 and the rack 67 remain engaged to ensure the stability of the cutter 68.

[0036] 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 in a horizontal position, and at the same time control the extension end of the second hydraulic cylinder 62 to extend slowly, so that the cutter 68 moves slightly in sync with the direction of the box movement while the tape is horizontally attached. The blade cuts the tape by "continuous attachment and slow pressure", avoiding tape stretching and deformation or incomplete cutting due to box movement.

[0037] After the tape is cut, the cutting structure 6 immediately resets to prepare for the next cut. Cutter posture reset: The extension end of the control electric push rod 66 extends, driving the rack 67 to rise, driving the gear 65 to rotate clockwise, and the rotating arm 64 flips with the pin shaft, so that the cutter 68 returns to the standby posture that is vertically located behind the packaging table 1. Height reset: Control the extension end of the second hydraulic cylinder 62 to retract, driving the rotating frame 63 and related components to descend to the initial low position, avoiding interference with the movement and sealing of the next housing; Continuous operation guarantee: Since the cutter 68 is located between the 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. The tape can enter the next packaging process without re-pulling, which effectively reduces equipment downtime and improves continuous packaging efficiency.

[0038] Working principle: First, complete the installation and guide path debugging of the high-temperature resistant tape. The operator unscrews 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) onto the sleeve shaft 51, and then screws the top plate 52 back onto the sleeve shaft 51 through the thread to limit the tape position. Then, the tape feed end is pulled and passes through the upper wall of the first guide roller 53 and the upper wall of the second guide roller 56 in sequence, ensuring that the adhesive side of the tape is facing up. When it passes through the tape groove 7, the tape conveying path is completed. The tape located on the upper wall of the first guide roller 53 is tilted to the right and conveyed 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 upper wall of the second guide roller 56 is kept higher than the surface of the packaging table 1 due to the support of the spring 59, waiting to contact the box. The packaging box will have its opening side in contact with the packaging table 1, or the box will have been first packaged in ordinary plastic. After the box is transported to the packaging table 1, a pair of flipping structures 3 will activate to coordinate positioning. The translation slide rail 31 will drive the lifting slide rail 32 to move in the left and right directions to adjust the left and right positions of the gripper 36. The lifting slide rail 32 will drive the feed slide rail 33 to move in the vertical direction to adapt to the height of the box. The feed slide rail 33 will drive the L-shaped top arm 34 to move back and forth, so that the two ends of the gripper 36 will respectively fit against the front side wall and the right side wall of the box for clamping. Through the above multi-dimensional adjustment, the gripper 36 will complete the centering clamping of the box, ensuring that the subsequent movement of the box is aligned with the packaging path.

[0039] The flipping structure 3 drives the clamped box to move to the right along the surface of the packaging table 1. When the lower wall of the box contacts the adhesive backing of the tape on the second guide roller 56, the box continues to move and applies downward pressure to the second guide roller 56. After being subjected to force, the second guide roller 56 drives the second roller frame 54 to rotate downward around the connection point with the first roller frame 50. At the same time, the flipping seat 57 on the second roller frame 54 moves along the telescopic rod 58. The telescopic rod 58 is subjected to force and flips with the help of the flipping seats 57 at both ends and the bearing 9. During the flipping and moving process, the spring 59 is compressed. The reverse elastic force of the spring 59 keeps the second guide roller 56 in close contact with the lower wall of the box, ensuring that the tape is evenly pasted in the middle of the box. During this process, the movement of the box synchronously pulls the tape to be released from the sleeve shaft 51. After being guided by the first guide roller 53, it continues to adhere to the box, completing single-sided sealing. After packaging, the box moves to the right side of the second guide roller 56, and the pressure cutting structure 6 can be activated to cut it. After cutting, the box is conveyed to the right through the conveyor belt body 42 in the conveying unit 4.

[0040] If the box needs to be wrapped and sealed on multiple sides, and then the lower wall of the box is sealed, the box moves to the upper left end of the lifting groove. At this time, the pair of first hydraulic cylinders 41 of the control conveyor unit 4 start to retract and drive the conveyor belt body 42 to move downward along the lifting port 8, opening the lifting port 8 to avoid interfering with the box flipping. Then the damping motor body 35 of the flipping structure 3 drives the gripper 36 to rotate. The gripper 36 drives the box to flip synchronously to a preset angle (such as 90 degrees or 180 degrees), so that the unsealed side of the box faces the tape on the second guide roller 56. After the flipping is completed, the tape is wrapped and packaged with the flipping. The first hydraulic cylinder 41 extends and drives the conveyor belt body 42 to rise and reset. When the flipping structure 3 drives the box to move, the left end of the conveyor belt body 42 waits for the cutting structure 6 to cut the tape.

[0041] 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 vertically, adjusting it to a position that matches the height of the tape; the electric push rod 66 extends and retracts, driving the rack 67 to descend. The rack 67 meshes with the gear 65, causing the gear 65 to drive the rotating arm 64 to rotate around the pin shaft within the rotating frame 63. The cutter 68, along with the rotating arm 64, flips from the "vertically located behind the packaging table 1" standby posture to the "parallel contact with the packaging table 1" cutting posture. At this time, during the flipping process of the cutter 68, the second hydraulic cylinder 62 drives the matching lifting and lowering to complete the flipping and cutting action of the cutter 68. The blade acts on the high-temperature resistant tape to complete the cutting; after cutting, the cutter 68 is driven to reset and detach from the packaging table 1 area to prevent obstruction of the box. Alternatively, when the cutter 68 is flipped to a horizontal position with the packaging table 1 supported by the support leg 2, the cutter 68 can be moved directly downward from above the tape by the second hydraulic cylinder 62 to achieve a flat direct pressure cut.
