Description

Technical Field

[0001] This invention patent relates to the technical field of foam box packaging, and more specifically, to a method for longitudinally wrapping foam boxes with tape. Background Technology

[0002] Foam boxes are box-shaped packaging containers made of foam plastic, which is a type of plastic with many tiny air pores inside. Foam boxes are often used for transporting fruits and fresh food or for packaging items.

[0003] Foam boxes generally consist of a box body and a lid. The box body has a cavity with an opening at the top, where items can be placed. The lid is then used to close the opening at the top of the cavity.

[0004] After the lid is closed over the top opening of the box cavity, it needs to be fixed relative to the box body so that the lid can be firmly sealed on the box body, thus keeping the box cavity in a sealed state.

[0005] In existing technology, when the lid is placed over the top opening of the box, a circumferential seam is formed between the lid and the box. Typically, this is done manually, by wrapping tape longitudinally around the lid and the box, covering the seam. The tape is used to fix the lid and box in place. This manual sealing method suffers from low sealing efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a method for longitudinally wrapping foam boxes with tape, which aims to solve the problem of low sealing efficiency of foam boxes in the prior art.

[0007] This invention is implemented as follows: a method for longitudinally wrapping foam boxes with adhesive tape, comprising the following wrapping steps:

[0008] 1) The foam box includes a box body and a box lid. The box body has a box cavity with a top opening for storing items. The lid covers the top opening of the box body. A circumferential butt joint is formed between the box lid and the box body.

[0009] The foam box is placed on the conveying structure, the box lid is placed on the top opening of the box body, and the foam box is moved from back to front by the conveying structure.

[0010] 2) The middle part of the transmission structure is provided with a winding station. The winding station has a placement structure for placing the tape roll and is arranged on the outside of the transmission structure. The tape roll is formed by winding tape into a roll. The tape roll has an initial section that can be freely unfolded.

[0011] The winding station has a cutting structure for cutting tape, and the initial segment is adhered to the cutting structure; the winding station is provided with a driving structure that drives the placement structure to move along the circumference of the winding station; the winding station has a pressing structure that attaches the initial segment to the box.

[0012] After the box is transported to the winding station by the conveying structure, the pressing structure will press against the initial segment and attach the initial segment to the box. Then, the driving structure will drive the placement structure to move around the longitudinal outer circumference of the foam box. The tape roll will be pulled out and longitudinally wrapped around the foam box, covering the joint seam and fixing the box and the lid relatively.

[0013] 3) After the placement structure rotates a set number of times around the longitudinal outer periphery of the foam box, the cutting structure cuts the tape.

[0014] Furthermore, in the packaging step 3), during the process of the placement structure rotating around the longitudinal outer periphery of the foam box, the transmission structure drives the foam box to be transmitted forward at a set speed. After the placement structure rotates around the longitudinal outer periphery of the foam box a set number of times, the foam box stops moving, and the cutting structure cuts the tape.

[0015] Furthermore, the driving structure includes a ring-shaped rotating ring that surrounds and forms an annular channel, the transmission structure passes through the annular channel, and the placement structure is connected to the rotating ring;

[0016] In the encapsulation step 2), after the box is transported to the winding station by the transmission structure, the foam box is placed in the annular channel. After the initial segment is attached to the box, the rotating ring rotates circumferentially, causing the placement structure to rotate circumferentially around the longitudinal outer periphery of the foam box.

[0017] Furthermore, the placement structure includes a placement box and a guide roller arranged outside the placement box, the placement box being connected to a rotating ring; the tape roll is rotatably placed in the placement box, the initial segment extends out of the placement box, passes around the guide roller, extends to the cutting structure, and is attached to the cutting structure.

[0018] Furthermore, the cutting structure is arranged below the transmission structure, including a connecting plate and cutting scissors that swing up and down relative to the connecting plate. The side of the connecting plate has a cutting edge, and the cutting scissors and the cutting edge are arranged vertically at intervals to form a cutting interval.

[0019] In the encapsulation step 3), after the placement structure rotates a set number of times around the longitudinal outer periphery of the foam box, the connecting plate moves towards the tape with the cutting scissors so that the tape is placed in the cutting interval. Then, the cutting scissors swing towards the cutting edge and use the cutting scissors and the cutting edge to cut the tape. The tape roll forms the initial segment, which is connected to the bottom of the connecting plate.

[0020] Furthermore, the bottom of the connecting plate forms an attachment surface, and the attachment surface is provided with a plurality of raised strips. The plurality of raised strips are arranged at intervals along the attachment direction of the initial segment on the attachment surface, and recessed strips are formed between adjacent raised strips. In the encapsulation step 3), after the cutting scissors and the cutting edge cut the tape, the initial segment is attached to the plurality of raised strips on the attachment surface.

[0021] Furthermore, the cutting edge is provided with a rolling cutting roller. In the packaging step 3), the cutting blade swings toward the cutting edge and cuts the tape placed in the cutting interval. During this process, the cutting roller is squeezed and rolled at a set angle by the cutting blade.

[0022] Furthermore, the winding station has a rolling pressure roller. In the packaging step 2), when the foam box moves to the winding station with the conveying structure, the pressure roller is located above the foam box and presses downward against the lid of the foam box.

[0023] Furthermore, in the packaging step 3), after the cutting structure cuts the tape wrapped around the foam box, the tape wrapped around the foam box has an end segment;

[0024] The pressing structure includes a laterally movable head made of elastic material, the movable head being sheet-shaped; in the encapsulation step 2), after the foam box moves to the winding station, the movable head abuts against the initial segment from bottom to top and moves laterally to attach the initial segment to the foam box; in the encapsulation step 3), after the cutting structure cuts the tape wrapped around the foam box, the movable head abuts against the final segment from bottom to top and moves laterally to attach the final segment to the foam box.

[0025] Furthermore, the moving head includes a protruding piece and a recessed piece, which are arranged at intervals to form an abutting gap; the center of the protruding piece protrudes upward to form a central protruding portion, and the two sides of the protruding piece are recessed downward to form a side recessed portion; the center of the recessed piece is recessed downward to form a central recessed portion, and the two sides of the recessed piece protrude upward to form a side protruding portion.

[0026] The central protrusion and the central depression are arranged in a front-to-back alignment, and the external depression and the side protrusion are arranged in a front-to-back alignment.

[0027] In the encapsulation step 2), the middle protrusion and the side protrusion abut against the initial segment from bottom to top, and the side recess and the middle recess are arranged at intervals with the initial segment; in the encapsulation step 3), the middle protrusion and the side protrusion abut against the end segment from bottom to top, and the side recess and the middle recess are arranged at intervals with the end segment.

[0028] Compared with existing technologies ， The foam box longitudinal winding and sealing method provided by the present invention involves the following steps: after the foam box moves to the winding station with the conveying structure, the driving structure drives the placement structure to rotate circumferentially relative to the longitudinal outer periphery of the foam box. The tape on the tape roll can then be wound along the longitudinal outer periphery of the foam box, thereby fixing the box body and the box cover relatively, thus achieving the sealing of the foam box with high sealing efficiency.

[0037] Reference Figure 1-5 The image shows a preferred embodiment of the present invention.

[0038] The method for sealing foam boxes by longitudinally wrapping tape includes the following sealing steps:

[0039] 1) The foam box includes a box body 200 and a box lid 201. The box body 200 has a box cavity with a top opening for storing items. The lid covers the top opening of the box body 200. A circumferentially arranged butt joint 202 is formed between the box lid 201 and the box body 200. The foam box is placed on the conveying structure 100, and the box lid 201 is placed on the top opening of the box body 200. The foam box is driven by the conveying structure 100 to be conveyed from back to front.

[0040] At this time, there are items inside the box 200, and the lid 201 is not sealed to the box 200, so the two can be directly separated.

[0041] 2) A winding station is provided in the middle of the transmission structure 100. The winding station has a placement structure for placing the tape roll and is arranged on the outside of the transmission structure 100. The tape roll is made by winding tape into a roll. The tape roll has an initial section that can be freely unfolded. The tape can be conventional transparent tape or other types of tape, etc.

[0042] The winding station has a cutting structure for cutting tape, and the initial segment is adhered to the cutting structure; the winding station is provided with a drive structure that drives the placement structure to move along the circumference of the winding station; the winding station has a pressing structure that attaches the initial segment to the box 200.

[0043] After the box 200 is conveyed to the winding station by the conveying structure 100, the pressing structure will press the initial segment and attach the initial segment to the box 200. Then, the driving structure will drive the placement structure to move around the longitudinal outer periphery of the foam box. The tape roll is pulled out and longitudinally wound around the foam box, and longitudinally covers the butt joint 202, fixing the box 200 and the box cover 201 relative to each other.

[0044] The tape is attached to the foam box using the initial segment. At this time, the tape adheres to the foam box. When the drive structure drives the placement structure to rotate, the tape in the tape roll can be pulled out.

[0045] 3) After the placement structure rotates a set number of times around the longitudinal outer circumference of the foam box, the cutting structure will cut the tape.

[0046] The foam box longitudinal winding and sealing method provided above, when the foam box moves to the winding station with the transmission structure 100, the driving structure drives the placement structure to rotate circumferentially relative to the longitudinal outer periphery of the foam box, and the tape on the tape roll can be wound along the longitudinal outer periphery of the foam box, thereby fixing the box body 200 and the box cover 201 relatively, realizing the sealing of the foam box with high sealing efficiency.

[0047] The longitudinal outer perimeter here refers to the outer perimeter along the height direction of the foam box. In contrast, the transverse outer perimeter is the outer perimeter in the horizontal direction, that is, along the direction of the butt joint 202.

[0048] In this embodiment, during the packaging step 3), as the placement structure rotates around the longitudinal outer periphery of the foam box, the transmission structure 100 drives the foam box to move forward at a set speed. After the placement structure rotates around the longitudinal outer periphery of the foam box a set number of times, the foam box stops moving, and the cutting structure cuts the tape.

[0049] In this way, the tape can be wrapped around the foam box a set number of times along its length, and it does not necessarily have to be wrapped in the same position. The specific number of wraps can be determined according to the wrapping requirements.

[0050] The drive structure includes a ring-shaped rotating ring 300, which surrounds and forms an annular channel. The transmission structure 100 passes through the annular channel, and the placement structure is connected to the rotating ring 300.

[0051] In the packaging step 2), after the box 200 is transported to the winding station by the transmission structure 100, the foam box is placed in the annular channel. After the initial segment is attached to the box 200, the rotating ring 300 rotates circumferentially, causing the placement structure to rotate circumferentially around the longitudinal outer periphery of the foam box.

[0052] By rotating the rotating ring 300 in its original position, the placement structure rotates around the longitudinal outer circumference of the foam box as the rotating ring 300 rotates.

[0053] In this embodiment, the placement structure includes a placement box 302 and a guide roller 303 arranged outside the placement box 302. The placement box 302 is connected to the rotating ring 300. The tape roll is placed in the placement box 302 in a rotating manner. The initial section extends out of the placement box 302, passes around the guide roller 303, extends to the cutting structure, and is attached to the cutting structure.

[0054] When the tape in the tape roll is pulled out, the tape roll is placed in the placement box 302, and guided by the guide rollers 303, the tape roll is prevented from getting tangled during the pulling process.

[0055] In this embodiment, the cutting structure is arranged below the transmission structure 100, including a connecting plate 500 and a cutting blade 501 that swings up and down relative to the connecting plate 500. The side of the connecting plate 500 has a cutting edge, and the cutting blade 501 and the cutting edge are arranged vertically at intervals to form a cutting interval 503.

[0056] In the packaging step 3), after the placement structure rotates around the longitudinal outer periphery of the foam box a set number of times, the connecting plate 500 moves towards the tape with the cutting scissors 501 so that the tape is placed in the cutting interval 503. Then, the cutting scissors 501 swings towards the cutting edge and uses the cutting scissors 501 and the cutting edge to cut the tape. The tape roll forms the initial segment, which is connected to the bottom of the connecting plate 500.

[0057] As the tape rotates in a circular motion around the longitudinal outer periphery of the foam box to achieve the winding process, the connecting plate 500 retracts to avoid interference. After the winding is completed, the connecting plate 500 moves so that the tape is threaded through the cutting interval 503, so that the cutting scissors 501 and the cutting edge can cut the tape.

[0058] In this embodiment, the bottom of the connecting plate 500 forms an attachment surface, and the attachment surface is provided with a plurality of raised strips. The plurality of raised strips are arranged at intervals along the attachment direction of the initial segment on the attachment surface, and recessed strips are formed between adjacent raised strips. In the encapsulation step 3), after the cutting scissors 501 and the cutting edge cut the tape, the initial segment is attached to the plurality of raised strips on the attachment surface.

[0059] The initial segment is attached to the raised strip, which makes it easy for the initial segment to be unfolded and to be attached to the foam box when it is sealed next time. The raised strip and the concave strip make it easy for the initial segment to be separated from the attachment surface.

[0060] In this embodiment, a cutting roller 502 is provided on the cutting edge and is arranged in a rolling manner. In the packaging step 3), the cutting scissors 501 swing toward the cutting edge and cuts the tape placed in the cutting interval 503. During this process, the cutting roller 502 is squeezed and rolled at a set angle by the cutting scissors 501.

[0061] By setting a cutting roller 502 at the cutting edge, when the cutting blade 501 presses against the tape and swings toward the cutting roller 502, it is easy for the tape to rub, and at the same time the cutting roller 502 rotates, thus making it easy to cut the tape.

[0062] In this embodiment, the winding station has a rolling pressure roller 301. In the packaging step 2), when the foam box moves to the winding station with the transmission structure 100, the pressure roller 301 is located above the foam box and presses downward against the lid 201 of the foam box.

[0063] By setting the pressure roller 301, the seal between the box cover 201 and the box body 200 can be better. After the tape is wrapped, the box cover 201 is not easy to detach from the box body 200 or become misaligned.

[0064] In this embodiment, during the packaging step 3), after the cutting structure cuts the tape wrapped around the foam box, the tape wrapped around the foam box has an end segment. At this time, the end segment is in a free state and is not attached to the foam box.

[0065] The pressing structure includes a laterally movable head 400 made of elastic material, which is sheet-shaped; in the encapsulation step 2), after the foam box moves to the winding station, the movable head 400 abuts against the initial segment from bottom to top and moves laterally to attach the initial segment to the foam box; in the encapsulation step 3), after the cutting structure cuts the tape wrapped on the foam box, the movable head 400 abuts against the end segment from bottom to top and moves laterally to attach the end segment to the foam box.

[0066] By moving the moving head 400 laterally, the end segment can be attached to the foam box, and before winding begins, the lateral movement of the moving head 400 facilitates the attachment of the initial segment to the foam box.

[0067] The moving head 400 includes a protruding piece 401 and a recessed piece 402, which are spaced apart to form an abutting gap; the center of the protruding piece 401 protrudes upward to form a central protrusion 4010, and the two sides of the protruding piece 401 are recessed downward to form side recesses 4011; the center of the recessed piece 402 is recessed downward to form a central recess 4020, and the two sides of the recessed piece 402 protrude upward to form side protrusions 4021.

[0068] The central protrusion 4010 and the central recess 4020 are arranged in a front-to-back alignment, and the recess and the side protrusion 4021 are arranged in a front-to-back alignment.

[0069] In packaging step 2), the central protrusion and the side protrusion 4021 abut against the initial segment from bottom to top, and the side recess 4011 and the central recess are arranged at intervals with the initial segment respectively; in packaging step 3), the central protrusion and the side protrusion 4021 abut against the final segment from bottom to top, and the side recess 4011 and the central recess are arranged at intervals with the final segment respectively.

[0070] By arranging raised pieces 401 and recessed pieces 402, the central raised portion 4010 of the raised piece 401 abuts against the middle of the initial or final segment, while the two side raised portions 4021 of the recessed piece 402 abut against the sides of the initial or final segment. The raised pieces 401 and recessed pieces 402 are arranged at a back-to-back interval. Along the width direction of the tape, the initial or final segment can be abutted against in multiple positions with a back-to-back misalignment. During the process of attaching the initial or final segment to the foam box, wrinkles in the width direction of the initial or final segment are avoided, which would result in unstable attachment.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
