DETAILED DESCRIPTION

[0032] ​The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1-5 As shown, a strip splicing device includes: a frame 1; a dual-station rotating mechanism 2, located at the bottom of the frame 1, including two strip fixing units 201 for fixing new and old strips respectively; an old paper traction mechanism 7, located at the top of the frame 1 for traction of old paper; a new paper laying mechanism, including a lifting clamping device 3 for vertical movement and clamping the starting end of the new paper strip; a pressing platform 4; a pressing execution mechanism, located on one side of the pressing platform 4 for pressing the new paper and old paper onto the pressing platform 4; and a splicing mechanism, including a cutting execution unit 5 and an adhesive execution unit 6, connected to the pressing execution mechanism, wherein the cutting execution unit 5 is used to cut the paper of the new strip, and the adhesive execution unit 6 is used to adhesive the ends of the new paper and the old paper.

[0035] Specifically, the two strip fixing units 201 of the dual-station rotating mechanism 2 are two strip fixing seats, which respectively fix the new strip and the old strip. After the new strip is fixed on the strip fixing seat, the dual-station rotating mechanism 2 can rotate 180° to rotate the new strip to the working position for convenient subsequent work. The old paper traction mechanism 7 is located above the dual-station rotating mechanism 2. When the old paper traction mechanism 7 tractions the old paper, the old paper adheres to the surface of the pressing platform 4. The lifting clamping device 3 consists of a drive mechanism and a mechanical clamp. The mechanical clamp is located on the drive mechanism. Driven by the mechanism, the paper moves downwards to the new strip. At this point, the strip holder, which holds the new strip, rotates, allowing the mechanical clamp to locate and clamp the starting end of the new paper. Driven by the drive mechanism, the mechanical clamp moves upwards, holding the starting end of the new paper. The pressing mechanism presses the new and old paper together onto the pressing platform 4, with the pressing mechanism adhering to the new paper and the pressing platform 4 adhering to the old paper. The cutting unit 5 is a cutter that cuts the new paper. The old paper traction mechanism 7 rotates continuously, causing the old paper to completely detach from the old strip. Finally, the bonding unit 6 bonds the new paper to the end of the old paper. This dual-station design enables seamless switching between new and old strips, significantly improving production continuity and reducing downtime. The traction, laying, pressing, cutting, and bonding processes are fully automated, reducing manual intervention and improving splicing accuracy and efficiency.

[0036] Example 2

[0037] like Figures 1-5As shown, a strip splicing device comprises a rack 1, a double-station rotating mechanism 2 arranged at the bottom of the rack 1 and comprising two strip fixing units 201 for respectively fixing new and old strips, an old paper traction mechanism 7 arranged at the top of the rack 1 for traction of old paper, a new paper laying mechanism comprising a lifting type clamping device 3 for vertical movement and clamping of the starting end of new paper of the new strip, a pressing platform 4, a pressing execution mechanism arranged at one side of the pressing platform 4 for pressing the new paper and the old paper on the pressing platform 4, and a splicing mechanism comprising a cutting execution unit 5 and an adhesive execution unit 6 connected with the pressing execution mechanism, the cutting execution unit 5 being used for cutting the paper of the new strip, and the adhesive execution unit 6 being used for adhering the end of the new paper to the old paper.

[0038] Specifically, the two strip fixing units 201 of the double-station rotating mechanism 2 are two strip fixing seats, which respectively fix the new strip and the old strip. After the new strip is fixed on the strip fixing seat, the double-station rotating mechanism 2 can rotate by 180° to rotate the new strip to the working station, facilitating subsequent work. The old paper traction mechanism 7 is above the double-station rotating mechanism 2. When the old paper traction mechanism 7 tractions the old paper, the old paper is attached to the surface of the pressing platform 4. The lifting type clamping device 3 is a driving mechanism and a mechanical clamp. The mechanical clamp moves downward to the new strip under the driving of the driving mechanism. At this time, the strip fixing seat on which the new strip is fixed rotates by itself, facilitating the mechanical clamp to find the starting end of the new paper and clamp it. Under the driving of the driving mechanism, the mechanical clamp clamping the starting end of the new paper moves upward. The pressing execution mechanism presses the new paper and the old paper on the pressing platform 4. The pressing execution mechanism is attached to the new paper, and the pressing platform 4 is attached to the old paper. The cutting execution unit 5 is a cutter, which cuts the new paper. The old paper traction mechanism 7 continuously rotates to make the old paper completely separate from the old strip. Then, the adhesive execution unit 6 adheres the end of the new paper to the old paper. The double-station design realizes seamless switching of the new and old strips, significantly improves the production continuity, and reduces the downtime. The traction, laying, pressing, cutting and adhering are fully automated, reducing manual intervention, and improving the splicing accuracy and efficiency.

[0039] Further, the old paper traction mechanism 7 comprises a rotating traction unit 701, which rotates to make the paper of the old strip continuously separate and keep in a tensioned state. Specifically, the rotating traction unit 701 is a traction roller group, which uses friction or roller transmission to make the old paper continuously separate from the strip and keep in a tensioned state through rotation tension, avoiding paper relaxation or stacking.

[0040] Further, the new paper laying mechanism further comprises a horizontal guide plate 8, a horizontal pushing member 9, a pressing mechanism 10, a first linear driving mechanism 11, a second linear driving mechanism 12, and a first driving device 13, the horizontal pushing member 9 is fixed on the first linear driving mechanism 11, the pressing mechanism 10 is fixed on the second linear driving mechanism 12, and the horizontal guide plate 8 is connected to the first driving device 13; the first linear driving mechanism 11 drives the horizontal pushing member 9 to guide the new paper to the surface of the horizontal guide plate 8, and the second linear driving mechanism 12 drives the pressing mechanism 10 to fix the new paper on the horizontal guide plate 8. Specifically, the first linear driving mechanism 11 is a gas cylinder or a lead screw, which drives the horizontal pushing member 9 to guide the new paper out of the strip and push it to the surface of the horizontal guide plate 8; the second linear driving mechanism 12 drives the pressing mechanism 10 to press down, and the pressing mechanism 10 is a pressing plate that fixes the new paper on the guide plate; and the first driving device 13 is a motor that drives the guide plate to rotate, for conveying the waste paper cut off by the cutting execution unit 5 to outside of the equipment.

[0041] Further, the bottom of the pressing mechanism 10 is provided with a rolling member 1001, so that the paper being pressed can move along the guide surface during the movement of the horizontal guide plate 8 driven by the first driving device 13. The rolling member 1001 at the bottom of the pressing mechanism 10 is a ball or a roller, which contacts the surface of the paper when the guide plate rotates, allowing the paper to slide along the guide surface while keeping the paper from separating from the guide plate by the pressing force. The low-friction movement reduces the friction between the paper and the guide plate.

[0042] Further, the pressing execution mechanism comprises a second driving device 14, a transmission assembly 15, a support frame 16, and a pressing execution unit 17, the pressing execution unit 17 is connected to the support frame 16, one end of the transmission assembly 15 is connected to the support frame 16, and the other end is connected to the second driving device 14, and the second driving device 14 drives the pressing execution unit 17 to press the new paper and the old paper through the transmission assembly 15. The second driving device 14 is a motor or a hydraulic cylinder, which drives the support frame 16 through the transmission assembly 15, drives the pressing execution unit 17 to move downward, and the pressing execution unit 17 is a pressing roller or a pressing plate that tightly presses the new and old papers on the platform.

[0043] Further, the splicing mechanism further comprises a third driving device 18 and a cam mechanism 19, the cam mechanism 19 is arranged in the support frame 16, the third driving device 18 is connected with the cam mechanism 19, and the cutting execution unit 5 and the bonding execution unit 6 are linked through the cam mechanism 19. The third driving device 18 is a motor, which synchronously drives the cutting execution unit 5 and the bonding execution unit 6 through the cam mechanism 19 to cut the new paper first and then bond the new paper with the old paper. The linkage control realizes the time sequence synchronization of cutting and bonding through a single driving source, reduces the complexity of the mechanism, improves the action coordination, and avoids the action delay caused by manual intervention in high-precision time sequence, so as to ensure the cutting and bonding positions and improve the splicing quality.

[0044] Further, the strip splicing device further comprises an adhesive tape supply mechanism 20 arranged at the side of the bonding execution unit 6, which provides adhesive tape to the bonding execution unit 6 to complete the joint of the new and old papers. The adhesive tape supply mechanism 20 is a reel and a guide roller, which continuously supplies adhesive tape to the bonding execution unit 6. The adhesive tape is a tape or a hot melt adhesive strip. The bonding execution unit 6 obtains the adhesive tape by grabbing or smearing and pastes it at the joint of the new and old papers. The automatic tape supply eliminates the need for manual replacement of adhesive materials, improves the splicing efficiency, and reduces labor costs. The standardized connection of the adhesive tape provides stable connection strength, avoids the randomness of traditional manual bonding, and ensures the splicing reliability.

[0045] Further, the bonding execution unit 6 comprises a bonding execution member 601 and a linkage mechanism 602, which drives the bonding execution member 601 to obtain the adhesive tape at the adhesive tape supply mechanism 20 and joint the new paper and the old paper separated from the old strip. The linkage mechanism 602 drives the bonding execution member 601 to reciprocate: first, it grabs the adhesive tape from the adhesive tape supply mechanism 20, and then it presses the adhesive tape to the joint of the new and old papers, so that the adhesive tape is firmly combined with the papers through pressure. The linkage mechanism 602 has an accurate movement trajectory, which ensures accurate positioning of the adhesive tape and avoids deviation or skew. One action completes the tape taking and bonding, reduces the process time, and adapts to high-speed production scenarios.

[0046] Further, the strip splicing device further comprises a strip conveying mechanism 21 arranged at the front end of the double-station rotating mechanism 2 for conveying new strips. The strip conveying mechanism 21 is a conveyor belt or a roller bed, which automatically conveys the new strips from the storage area to the front end of the double-station rotating mechanism 2 and lifts the new strips. Automatic feeding reduces the time for manual handling and installation of the strips, improves the continuous operation capability of the equipment, and directional conveying ensures that the new strips arrive at the specified position in the correct posture, which provides convenience for subsequent positioning and fixing.

[0047] Further, the strip splicing device further comprises a strip positioning mechanism 22, including a linear drive and a push plate, which positions the new strip conveyed by the strip conveying mechanism 21 to the strip fixing unit 201 of the double-station rotating mechanism 2. The linear drive is a pneumatic cylinder, which drives the push plate to push the new strip conveyed by the strip conveying mechanism 21 to the fixing unit of the double-station rotating mechanism 2, and realizes accurate positioning through a limiting device, so as to ensure that the strip axis is aligned with the fixing unit. The manual adjustment time is reduced, and the material replacement efficiency is improved.
