Description

Technical Field

[0001] This invention relates to a technical field, and more particularly to a servo-driven ring-wrap box sealing machine. Background Technology

[0002] With the rapid development of e-commerce logistics and industrial packaging, corrugated cardboard boxes, as the mainstream packaging form for bulk goods, have placed higher demands on the efficiency, quality, and automation of sealing and reinforcement. Circumferential wrapping sealing machines use tape to wrap around the entire circumference of the cardboard box, effectively improving the sealing strength and providing dustproof, moisture-proof, and anti-fragmentation functions. They are widely used in bulk cardboard box packaging processes in the food, electronics, home appliance, and logistics warehousing industries.

[0003] The shortcomings of the existing technology are that, due to factors such as conveyor vibration and loading misalignment, the cartons fed by the upstream conveyor line or by manual loading often become skewed or twisted. After entering the ring winding station in an inclined posture, the tape winding path is misaligned with the edge of the carton, which easily leads to defects such as tape wrinkles, poor edge and corner adhesion, and uneven overlap, thus reducing the actual effect of winding and reinforcement. Summary of the Invention

[0004] The purpose of this invention is to provide a servo-driven ring-wrap carton sealing machine. The pusher unit has a movable structure that abuts against one side of the carton. The pusher unit is driven by a drive seat to straighten the carton, which is tilted at an angle to the direction of movement, and abut against the limit frame. This allows the carton to correct its posture on the conveyor platform, ensuring that the tape wrapped by the carton sealing machine adheres to the carton smoothly without wrinkles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a servo-driven circular wrapping carton sealing machine, used for conveying cartons horizontally to the sealing machine, wherein one end of the sealing machine is provided with a feeding end for carton feeding, and the other end of the sealing machine is provided with a discharging end, and an interval is reserved between the feeding end and the discharging end for the sealing machine tape to wrap and seal the carton; the feeding end includes: a conveying platform; a limiting frame, installed on the conveying platform, the limiting frame being used to limit the movement direction of the carton; a pushing mechanism, including a drive seat and a pushing unit, the drive seat being installed on the conveying platform, the pushing unit being installed on the drive seat, and the pushing unit being located on the opposite side of the limiting frame; the pushing unit is configured such that: when the carton moves along the conveying platform to the limiting frame, the pushing unit can adjust the carton posture before the carton enters the sealing machine, and align the carton with the limiting frame horizontally until one end of the carton enters the sealing machine.

[0006] As a further description of the above technical solution:

[0007] The pushing unit includes a pushing plate, which is rotatably connected to the drive seat. The axis of the pushing plate is horizontally set and is horizontally aligned with the top surface of the conveying platform.

[0008] As a further description of the above technical solution:

[0009] The pusher plate is symmetrically rotatably connected to two connecting rods at both ends. The ends of the two connecting rods away from the pusher plate are movably connected to the drive seat. The two connecting rods and the pusher plate form a triangular structure.

[0010] As a further description of the above technical solution:

[0011] One end of the connecting rod is provided with a return spring, which is installed on the drive seat. The return spring is configured to adjust the push plate and the limiting frame from horizontal alignment to an open and tilted state when the carton is separated from the push plate.

[0012] As a further description of the above technical solution:

[0013] The drive base includes a positioning frame and a movable frame; the movable frame is slidably disposed on the positioning frame, and the movable frame is rotatably connected to the pusher plate. The pusher plate moves along the positioning frame through the movable frame to push the carton to fit against the limiting frame.

[0014] As a further description of the above technical solution:

[0015] The positioning frame has a sliding groove, and two sliding grooves are slidably connected to a movable block, which is rotatably connected to the connecting rod.

[0016] As a further description of the above technical solution:

[0017] One end of the movable frame is fixedly connected to a tension spring, which is installed on the positioning frame. The tension spring elastically drives the movable frame to move in a directional manner along the positioning frame.

[0018] As a further description of the above technical solution:

[0019] The positioning frame is provided with a drive rod, which drives the movable frame to move along the orientation frame and drives the movable block to move along the orientation groove.

[0020] As a further description of the above technical solution:

[0021] One end of the positioning frame is provided with a locking member, which is configured to lock the movable frame to the positioning frame when the connecting rod drives the push plate to align the carton.

[0022] As a further description of the above technical solution:

[0023] The locking component includes a locking bar, the end of which is provided with a protrusion, which engages with a locking groove in the movable frame.

[0024] This invention provides a servo-driven ring-wrap box sealing machine, which has the following advantages:

[0025] 1. In this invention, the pushing unit itself is set up to abut against one side of the box body, and the pushing unit is driven by the drive seat to straighten the carton that is tilted at an angle to the direction of movement and abut against the limit frame. This allows the carton to correct its own posture on the conveying platform, ensuring that the tape wrapped around the sealing machine ring is flat and wrinkle-free at the adhesion point to the carton.

[0026] 2. In this invention, a flexible alignment and pushing structure is used to complete the posture correction by gradually aligning the boxes through surface contact. This allows the system to adapt to corrugated boxes and cardboard boxes of different materials and specifications without damaging the box body. This solves the problems of existing correction mechanisms where rigid clamping easily damages the boxes and hard guides easily scratch the box body. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figure 1-7 A servo-driven circular wrapping carton sealing machine is used to horizontally convey cartons 5 into a sealing machine 1. The sealing machine 1 has a feeding end for feeding the cartons 5 at one end and a discharging end at the other end. An interval is reserved between the feeding end and the discharging end for the sealing machine 1 to wrap and seal the cartons 5 with tape. The feeding end includes:

[0037] Conveying platform 2;

[0038] Limit frame 3 is installed on conveyor platform 2 and is used to limit the movement direction of carton 5;

[0039] The pushing mechanism 4 includes a drive base 42 and a pushing unit 41. The drive base 42 is installed on the conveying platform 2, and the pushing unit 41 is installed on the drive base 42. The pushing unit 41 is located on the opposite side of the limit frame 3.

[0040] The pushing unit 41 is configured such that when the carton 5 moves along the conveyor platform 2 to the limit frame 3, the pushing unit 41 can adjust the posture of the carton 5 before the carton 5 enters the sealing machine 1, and then align the carton 5 with the limit frame 3 in a horizontal position until one end of the carton 5 enters the sealing machine 1.

[0041] In this embodiment, the carton 5 is a rectangular corrugated carton 5. The carton 5 is placed on the feeding end connected to the sealing machine 1. After the sealing machine 1 wraps and seals the carton 5, it is moved out from the discharge end. The feeding end and the discharge end are horizontally aligned. The conveying platform 2 is composed of a support frame 21 and rollers 2. The rollers 2 are divided into an electric roller 2 for driving the carton 5 to move laterally and a conveying roller 2 for supporting the carton 5. The limiting frame 3 fixed to the conveyor consists of a fixed seat 31 and a guard 32. The guard 32 has inclined surfaces at both ends to facilitate the guidance of the carton 5. The limiting frame 3 with a fixed structure is symmetrically arranged on the conveying platform 2 at the discharge end. The conveying platform 2 at the feeding end is on one side. A limiting frame 3 is provided, and a pusher mechanism 4 with a movable structure is provided at the other end of the limiting frame 3. In the pusher mechanism, the drive seat 42 is fixedly connected to the conveying platform 2. The pusher unit 41 connected to one end of the drive seat 42 first pushes the carton 5 on the conveying platform 2 to one side of the carton through its own movable setting structure during the movement. The pusher unit 41 is driven by the drive seat 42 to straighten the carton 5, which is tilted at an angle with the direction of movement, and push it against the limiting frame 3. This achieves the carton 5 on the conveying platform 2 by correcting its own posture, ensuring that the tape wrapped around the sealing machine 1 is flat and wrinkle-free at the adhesion point to the carton 5.

[0042] The pushing unit 41 includes a pushing plate 401, which is rotatably connected to the drive seat 42. The axis of the pushing plate 401 is horizontally set and is horizontally aligned with the top surface of the conveying platform 2.

[0043] In this embodiment, the pusher plate 401 in the pusher unit 41 has a rectangular strip structure. Inclined surfaces are provided at both ends of the pusher plate 401 to guide the carton 5. The pusher plate 401 is arranged parallel to the conveying platform 2, and one end of the pusher plate 401 is attached to one side of the carton 5.

[0044] The pusher plate 401 is symmetrically rotatably connected to two connecting rods 402 at both ends. The ends of the two connecting rods 402 away from the pusher plate 401 are movably connected to the drive seat 42. The two connecting rods 402 and the pusher plate 401 form a triangular structure.

[0045] In this embodiment, the pusher plate 401 has symmetrically provided grooves 4011 at both ends. A rotating shaft is fixedly connected in the groove 4011. The rotating shaft is rotatably connected to the connecting rod 402. The end of the connecting rod 402 away from the pusher plate 401 is slidably connected to the movable seat. The two connecting rods 402 and the pusher plate 401 form a triangular structure. When the two connecting rods 402 are symmetrically arranged on both sides of the movable seat, the pusher plate 401 connected to the two connecting rods 402 is aligned parallel to the guard edge 32 in the limit frame 3 under the drive of the drive seat 42. This realizes that the pusher plate 401 and the guard edge 32 are adjusted from tilted and crossed to horizontal alignment, which makes it easier for the carton 5 at one end of the pusher plate 401 to change from tilted angle to parallel with the guard edge 32, which facilitates further adjustment of the carton 5.

[0046] One end of the connecting rod 402 is provided with a return spring 43, which is installed on the drive seat 42. The return spring 43 is configured to adjust the pusher plate 401 and the limit frame 3 from horizontal alignment to an open and tilted state when the carton 5 is separated from the pusher plate 401.

[0047] In this embodiment, the return spring 43 at one end of the connecting rod 402 is fixed by the fixing block 431. The fixing block 431 is respectively provided on the movable seat and the connecting rod 402. When the connecting rod 402 is not under force (the driving seat 42 applies a thrust), the return spring 43 elastically drives the connecting rod 402 to move in a direction along the driving seat 42. The pusher plate 401 connected to the connecting rod 402 rotates along its connection with the movable frame 422, so that the pusher plate 401 changes from a parallel structure to an inclined structure. The open structure formed by the inclination is used for guiding the carton 5.

[0048] The drive base 42 includes a positioning frame 421 and a movable frame 422; the movable frame 422 is slidably disposed on the positioning frame 421, and the movable frame 422 is rotatably connected to the pusher plate 401. The pusher plate 401 moves along the positioning frame 421 through the movable frame 422 to push the carton 5 to fit against the limit frame 3.

[0049] In this embodiment, the positioning frame 421 in the drive base 42 is fixed on the support frame 21 of the conveying platform 2. The positioning frame 421 is movably connected to the movable frame 422. One end of the movable frame 422 is rotatably connected to the middle of the push plate 401. When the push plate 401 is driven by the elasticity of the return spring 43, the push plate 401 rotates along the connection of the movable plate. When the movable frame 422 moves along the orientation frame, the push plate 401 connected to the movable frame 422 abuts against one end of the carton 5 and drives the carton 5 to abut against the guard edge 32 at the other end of the conveying platform 2, so that the carton 5 can complete the correction of its own posture through the push plate 401.

[0050] The positioning frame 421 has a sliding groove 4201, and two sliding grooves 4201 are slidably connected to a movable block 403, and the movable block 403 is rotatably connected to the connecting rod 402;

[0051] In this embodiment, the positioning frame 421 has a cavity, and a sliding groove 4201 is provided on the inner wall of the cavity. The grooves are symmetrically distributed on both sides of the positioning frame. The movable block 403, which is slidably connected in the sliding groove 4201, is rotatably connected to the connecting rod 402. When the return spring 43 elastically drives the pusher plate 401, the two movable blocks 403 move along the sliding groove 4201 to both ends through the connecting rod 402. When the two movable blocks 403 retract and overlap, the pusher plate 401 moves through the connecting rod 402 connected to the movable block 403. When the two connecting rods 402 are symmetrically distributed at both ends of the positioning frame 421, the pusher plate 401 is horizontally aligned with the guard edge 32.

[0052] One end of the movable frame 422 is fixedly connected to a tension spring 423, which is installed on the positioning frame 421. The tension spring 423 elastically drives the movable frame 422 to move in a directional manner along the positioning frame 421.

[0053] In this embodiment, a tension spring 423 is fixedly connected to one end of the movable frame 422 away from the pusher plate 401, and the other end of the tension spring 423 is fixedly connected to the orientation frame. The tension spring 423 elastically resets the movable frame 422 driven by the drive seat 42. When the movable frame 422 drives the pusher plate 401 to reset, the carton 5 is located between the pusher plate 401 and the guard edge 32. Under the elastic drive of the reset spring 43, the pusher plate 401 is inclined and pressed against the carton 5 to avoid the carton 5 from shifting during the conveying process. On the other hand, it reduces the friction between the pusher plate 401 and the outer wall of the carton 5.

[0054] The positioning frame 421 is provided with a drive rod 44, which drives the movable frame 422 to move along the directional frame. The drive rod 44 drives the movable block 403 to move along the directional groove.

[0055] In this embodiment, the drive rod 44 passing through the positioning frame 421 is fixed to the drive pump 45, and the drive pump 45 is fixed to the orientation frame. The drive pump 45 drives the drive rod 44 to move along the orientation frame toward the pusher plate 401. The pusher block 441 fixed to the drive rod 44 retracts and overlaps the two movable blocks 403, so that the pusher plate 401 moves the carton 5 and the guard edge 32 in a parallel state. Under the further drive of the drive rod 44, the pusher plate 401 connected to the movable frame 422 is pushed toward one end of the guard edge 32, so that the carton 5 is pressed against the guard edge 32.

[0056] The positioning frame 421 is provided with a locking member 46 at one end. The locking member 46 is configured to lock the movable frame 422 and the positioning frame 421 when the connecting rod 402 drives the push plate 401 to straighten the carton 5.

[0057] The locking member 46 includes a locking strip 461, and a protrusion is provided at the end of the locking strip 461. The protrusion engages with the locking groove 462 opened in the movable frame 422.

[0058] In this embodiment, the locking strip 461 in the locking member 46 is movably connected to the directional frame. When the abutment 442 fixed to the end of the drive rod 44 abuts the trapezoidal block fixed in the locking block, the trapezoidal block drives the locking strip 461 to move down, thereby separating the locking strip 461 from the locking groove 462 at the bottom of the movable frame 422. This allows the movable frame 422 to remain locked when the connecting rod 402 drives the push plate 401 to move. When the movable frame 422 drives the push plate 401 to move, the locking groove 462 separates from the locking strip 461 and is reset by the first spring 463 located at both ends of the locking strip 461, so that the movable frame 422 can be locked again after reset.

[0059] Working principle: The entire feeding system works automatically according to the following sequence:

[0060] Initial standby state: The reset spring drives the connecting rod to move the movable block along the slide groove to both ends, the push plate is in an inclined state, and forms an open guide structure with the limit frame guard edge; the movable frame is in the retracted position under the action of the tension spring, and the locking strip is inserted into the locking groove of the movable frame to lock and fix the movable frame.

[0061] Carton feeding stage: The electric roller drives the carton to move forward along the conveyor platform, and enters the correction area through the open guide formed by the pusher plate and the limit frame. The side wall of the carton contacts the inclined pusher plate.

[0062] Pushing into the carton stage: The drive rod continues to extend forward, pushing the unlocked movable frame forward along the positioning frame, which in turn drives the parallel pusher plate to push the corrected carton horizontally until it is completely in contact with the edge of the limit frame, until the end of the carton enters the working area of ​​the carton sealing machine, completing the feeding.

[0063] Mechanism reset phase: After the carton enters the sealing machine, the drive rod retracts, the tension spring pulls the movable frame to reset, and the reset spring drives the connecting rod to return the pusher plate to the inclined open state; the locking strip, under the action of the spring, engages with the locking groove of the movable frame and locks again, and the system returns to the standby state, waiting for the next carton to be fed. In the reset state, the inclined pusher plate can gently abut against the side wall of the carton, which not only prevents the carton from shifting during conveying but also reduces frictional resistance and ensures smooth conveying.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and concept of the present invention, should be covered within the scope of protection of the present invention.
