[0008] Optionally, a second roller is provided between the first roller and the tape mounting post, the second roller being used to contact the adhesive surface of the tape.

[0009] Optionally, an elastic buckle is provided on the first rotating wheel, which cooperates with the first rotating wheel to press the tape.

[0010] Optionally, the cutting blade on the base can rotate toward or away from the direction of the tape pulled from the first roller, and the cutting blade is also connected to an elastic element for driving the cutting blade to deflect toward the side away from the tape; it also includes: a first support column, which cooperates with the cutting blade, and through the relative movement of the first support column and the cutting blade, the first support column drives the cutting blade to overcome the elastic force of the elastic element and deflect toward the other side that can cut the tape.

[0011] Optionally, a pre-compression element is also included, disposed prior to the compaction roller, the pre-compression element having a pre-compression surface for contacting one side of the corner of the product to be corner-applied and an extension surface extending toward the other side of the corner of the product to be corner-applied.

[0012] Optionally, the compaction roller is connected to a front-to-back moving device and a vertical moving device, wherein the vertical moving device can drive the compaction roller to reciprocate along the direction parallel to the bisector of the angle of the product to be compacted.

[0013] Optionally, it further includes: a first edge pressing device, the first edge pressing device being connected to the base, the first edge pressing device being driven by a first driving device to press against one side of the corner of the product to be coated with corner tape.

[0014] Optionally, it further includes: a second edge pressing device, the second edge pressing device being connected to the crossbeam, the second edge pressing device being driven by a second driving device to press against the other side of the corner of the product to be coated with corner tape.

[0015] The present invention provides a packaging machine, including the corner sealing machine described in any one of the above embodiments.

[0016] The technical solution of this invention has the following advantages:

[0017] 1. The corner sealing machine provided by this invention, in use, fixes the tape roll to the tape mounting column, and pulls the tape out through the first rotating wheel. When the product moves to the tape sealing station, the side of the product contacts the first rotating wheel, and the tape is adhered to one side of the corner of the product. The compacting surface of the compacting roller behind the first rotating wheel contacts the corner of the product to be sealed with tape, and the compacting surface contacts both sides of the corner of the product to be sealed with tape. As the base slides forward on the crossbeam, the tape is continuously pulled out, and the compacting roller behind it compacts the tape. When it moves to the front of the product, the cutter head on the cutting blade cuts the tape, and the corner sealing machine resets. The corner sealing machine provided by this invention achieves continuous tape application to the corners of the product, and the tape is flat and compacted without wrinkles.

[0018] 2. The corner sealing machine provided by the present invention has a tape mounting column with a tape roller adapted to the tape roll. During use, the tape roll is rotated to facilitate tape pulling out.

[0019] 3. The corner sealing machine provided by the present invention has a second rotating wheel between the first rotating wheel and the tape mounting column. In use, the second rotating wheel is used to contact the adhesive surface of the tape and guide the tape to be pulled out.

[0020] 4. The corner sealing machine provided by the present invention has an elastic buckle on the first rotating wheel. The elastic buckle cooperates with the first rotating wheel to press the tape. In use, the tape passes through the gap between the first rotating wheel and the elastic buckle. The elastic force increases the friction between the tape and the first rotating wheel. When the tape is cut, it can prevent the tape from shrinking back or sticking to the base.

[0021] 5. In use, the corner sealing machine provided by the present invention allows the cutting blade on the base to rotate closer to or further away from the direction of the tape pulled from the first rotating wheel. The cutting blade is also connected to an elastic element, which drives the cutting blade to deflect away from the tape. The first support column cooperates with the cutting blade, and through the relative movement of the first support column and the cutting blade, the first support column drives the cutting blade to overcome the elastic force of the elastic element and deflect towards the other side that can cut the tape.

[0022] 6. The corner sealing machine provided by the present invention further includes a pre-pressing component, which has a flat surface that contacts one side of the corner of the product to be sealed with corner tape and an extension surface that extends toward the other side of the corner of the product to be sealed with corner tape. In use, as the base moves forward, the flat surface of the pre-pressing component pre-presses the tape adhered to the side of the product, and the protruding extension surface on the pre-pressing component presses against the unbonded part of the tape to prevent the tape from curling.

[0023] 7. In use, the corner sealing machine provided by the present invention uses a front and rear moving device to drive the compacting roller to move back and forth, and an up and down moving device to drive the compacting roller to move back and forth along the direction of the bisector of the angle of the product to be corner sealed, thereby completing the action of pressing and releasing the corner sealing tape.

[0024] 8. The corner sealing machine provided by the present invention further includes a first edge pressing device, which is connected to the base. In use, the first edge pressing device is driven by the first driving device to press against one side of the corner of the product to be sealed with corner tape, so as to prevent the product from spreading out during the tape application process.

[0025] 9. The corner sealing machine provided by the present invention further includes a second edge pressing device. The second edge pressing device is connected to the crossbeam. In use, the second edge pressing device is driven by the second driving device to press against the other side of the corner of the product to be sealed with corner tape, so as to prevent the product from spreading out during the tape application process.

[0026] 10. The packaging machine provided by the present invention has any of the above advantages because it adopts the corner sealing machine described above. Attached Figure Description

[0040] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0041] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] like Figure 1 , Figure 2As shown, this embodiment provides a corner sealing machine, including: a crossbeam 1, on which a base 2 is slidably connected; a tape mounting post 3 connected to the base 2, the tape mounting post 3 being adapted to mount a roll of tape; a first rotating wheel 4 connected to the base 2, the first rotating wheel 4 being located on the side of the tape mounting post 3 near the product 5 to be sealed with corner tape, the first rotating wheel 4 pulling out the tape on the tape mounting post 3 and adhering it to one side of the corner of the product 5 to be sealed with corner tape; and a cutting blade. The cutting blade 6 is movably connected to the base 2 and has a blade head for cutting the pulled-out tape. The compacting roller 7 is connected to the base 2 and is located behind the first rotating wheel 4. The compacting roller 7 is a flexible wheel, and the compacting surface 8 of the compacting roller 7 is opposite to the corner of the product 5 to be corner-cut. When the compacting surface 8 of the compacting roller 7 contacts the corner of the product 5 to be corner-cut, the compacting surface 8 contacts both sides of the corner of the product 5 to be corner-cut.

[0045] In use, the tape roll is fixed to the tape mounting post 3, and the tape is pulled out by the first rotating wheel 4. When the product moves to the tape sealing station, the side of the product contacts the first rotating wheel 4, and the tape is adhered to one side of the corner of the product. The compaction surface 8 of the compaction roller 7 behind the first rotating wheel 4 contacts the corner of the product 5 to be corner-sealed, and the compaction surface 8 contacts both sides of the corner of the product 5 to be corner-sealed. The base 2 is driven to move on the crossbeam 1 by the belt drive device. As the base 2 slides forward on the crossbeam 1, the tape is continuously pulled out, and the compaction roller 7 behind it compacts the tape. When it moves to the front end of the product, the blade on the cutting knife 6 cuts the tape, and the corner-sealing machine resets. The corner-sealing machine provided by this invention realizes continuous tape application to the corner of the product, and the tape is flat and compacted without wrinkles.

[0046] like Figure 2 As shown, in the corner sealing machine provided in this embodiment, the tape mounting column 3 is provided with a tape roller 9 that is adapted to the tape roll. When in use, it drives the tape roll to rotate, making it convenient to pull out the tape.

[0047] like Figure 3 As shown, in the corner sealing machine provided in this embodiment, a second roller 10 is provided between the first roller 4 and the tape mounting post 3. The second roller 10 is used to contact the adhesive surface of the tape, thereby guiding the tape out and tightening the tape to prevent the tape from springing back. Specifically, the second roller 10 can be made of metal to prevent the adhesive on the tape from adhering to the second roller 10.

[0048] like Figure 4As shown, in the corner sealing machine provided in this embodiment, an elastic buckle 11 is provided on the first rotating wheel 4. The elastic buckle 11 cooperates with the first rotating wheel 4 to press the tape. In use, the tape passes through the gap between the first rotating wheel 4 and the elastic buckle 11. The elastic force increases the friction between the tape and the first rotating wheel 4. When the tape is cut, it can prevent the tape from retracting or sticking to the base 2.

[0049] like Figure 3 , Figure 4 As shown, in the corner sealing machine provided in this embodiment, the tape mounting post 3 and the first rotating wheel 4 are connected to the first fixed plate 12. The first fixed plate 12 can be driven to move up and down by a moving device, so that the first rotating wheel 4 contacts one side of the product 5 to be corner sealed with tape. The cutting blade 6 is rotatably connected to the back of the first fixed plate 12. The cutting blade 6 cuts the tape adhered to the product 5 to be corner sealed by rotating. An elastic element is connected to the cutting blade 6, which is used to drive the cutting blade 6 to deflect away from the tape. Specifically, a torsion spring is connected to the rotating shaft of the cutting blade 6, which is used to drive the cutting blade 6 to rotate. In addition, as an alternative embodiment, the torsion spring can be replaced with other elastic devices, such as a tension spring connected to one side of the cutting blade 6.

[0050] like Figure 3 As shown, the corner sealing machine provided in this embodiment further includes: a second fixed plate 13, on which a first support column 14 is connected. The first fixed plate 12 is movably connected to the second fixed plate 13. When the first fixed plate 12 and the second fixed plate 13 move relative to each other, the first support column 14 cooperates with the cutting blade 6. Through the relative movement of the first support column 14 and the cutting blade 6, the first support column 14 drives the cutting blade 6 to overcome the elastic force of the elastic element and deflect towards the side capable of cutting the tape. Specifically, when the moving device drives the first fixed plate 12 to move downward, the cutting blade 6 is driven downward by the first fixed plate 12, and at the same time, the cutting blade 6 is driven upward by the elastic element, so that the upper edge of the cutting blade 6 always abuts against the first support column 14. When the moving device drives the first fixed plate 12 to move upward, the cutting blade 6 is driven upward by the first fixed plate 12. At this time, due to the obstruction of the first support column 14, the cutting blade 6 overcomes the elastic force of the elastic element and deflects downward, so that the cutting edge of the cutting blade 6 applies pressure to the tape and cuts the tape.

[0051] like Figure 5As shown, in the corner sealing machine provided in this embodiment, the compacting roller 7 is mounted on the second fixed plate 13. A front-to-back moving device 15 is mounted on the second fixed plate 13. The driving end of the front-to-back moving device 15 is connected to a connecting plate 16. The lower half of the connecting plate 16 has an inclined surface that leans towards the base 2. A vertical moving device 17 is mounted on the inclined surface, and the driving end of the vertical moving device 17 is connected to the compacting roller 7. The vertical moving device 17 drives the compacting roller 7 to reciprocate along the direction parallel to the bisector of the angle of the product 5 to be corner-sealed, thereby causing the compacting surface 8 of the compacting roller 7 to contact the corner of the product 5 to be corner-sealed. The front-to-back moving device 15 is used to adjust the distance between the compacting roller 7 and the pre-compression component 18.

[0052] like Figure 2 , Figure 6 and Figure 7 As shown, the corner sealing machine provided in this embodiment also includes a pre-compression component 18. The pre-compression component 18 is disposed before the compaction roller 7. The pre-compression component 18 can be driven to move up and down by a moving device, thereby approaching or moving away from the product 5 to be corner-sealed. The pre-compression component 18 has a pre-compression surface for contacting one side of the corner of the product 5 to be corner-sealed and an extension surface extending toward the other side of the corner of the product 5 to be corner-sealed. In use, as the base 2 moves forward, the flat surface of the pre-compression component 18 pre-compresses the tape adhered to the side of the product, and the protruding extension surface on the pre-compression component 18 presses against the unadheded portion of the tape to prevent the tape from curling.

[0053] like Figure 7As shown, the pre-compression component 18 includes a pre-compression roller 19 and a support frame 20. The pre-compression roller 19 is embedded in the support frame 20. The pre-compression roller 19 has a rolling surface 21 for contacting one side of the corner of the product 5 to be coated with corner tape, and the rolling surface 21 forms the pre-compression surface. The pre-compression roller 19 also has a flange 22 protruding toward the other side of the corner of the product 5 to be coated with corner tape, and the side of the flange 22 facing the product 5 to be coated with corner tape forms the extension surface. In use, the rolling surface 21 of the pre-compression roller 19 pre-compresses the tape adhered to the upper side of the product, and the protruding flange 22 on the pre-compression roller 19 presses against the unbonded part of the tape to prevent the tape from curling. The support frame 20 has a lower surface 23 for contacting one side of the corner of the product 5 to be coated with corner tape, and this lower surface 23 forms the pre-compression surface. The support frame 20 also has an extension plate 24 protruding toward the other side of the corner of the product 5 to be coated with corner tape, and the side of the extension plate 24 facing the product 5 to be coated with corner tape forms the extension surface. Alternatively, as an alternative embodiment, the pre-compression surface and the extension surface may be provided in only one set on the support frame 20 or the pre-compression roller 19, or one of them may be provided on the support frame 20 and the pre-compression roller 19 respectively.

[0054] like Figure 2 , Figure 8 As shown, the corner sealing machine provided in this embodiment further includes a first edge pressing device 25, which is connected to the base 2. The first edge pressing device 25 is driven by a first driving device 29 to press against one side of the corner of the product 5 to be sealed with corner tape. In use, the first edge pressing device 25 moves forward with the base 2 to press the side of the product firmly, preventing the product from spreading out during the tape application process.

[0055] like Figure 8As shown, in the corner sealing machine provided in this embodiment, the first edge pressing device 25 includes: a rotating plate 26, which is rotatably connected to the second fixed plate 13. One end of the rotating plate 26 is equipped with an edge pressing wheel 27, and an elastic element is also connected to the rotating plate 26. The elastic element has an elastic force that drives the rotating plate 26 to deflect away from the product 5 to be corner-sealed. A second support column 28 cooperating with the rotating plate 26 is installed on the base 2. The second fixed plate 13 moves relative to the base 2, thereby allowing the second support column 28 to move relative to the rotating plate 26. Specifically, a first driving device 29 is provided between the second fixed plate 13 and the base 2. Driven by the first driving device 29, the second fixed plate 13 can move up and down relative to the base 2. When the second fixed plate 13 moves upward, the rotating plate 26 deflects upward under the drive of the elastic element, thereby causing the pressing wheel 27 to disengage from the product 5 to be coated with corner tape, so as to press the edge of the next product 5 to be coated with corner tape. When the second fixed plate 13 moves downward, the rotating plate 26 moves downward simultaneously with the second fixed plate 13, while the second support column 28 does not move on the base 2. At this time, under the drive of the second support column 28, the rotating plate 26 deflects downward against the elastic force of the elastic element, thereby causing the pressing wheel 27 to contact the outer edge of the corner of the product 5 to be coated with corner tape.

[0056] like Figure 1 , Figure 9 As shown, the corner sealing machine provided in this embodiment further includes a second edge pressing device. The second edge pressing device is connected to the crossbeam 1 and is driven by a second driving device 33 to press against the other side of the corner of the product 5 to be sealed with corner tape. This prevents the product from spreading during tape application. Specifically, the second edge pressing device includes an edge pressing plate 30, which is mounted on an edge pressing bracket 31. Both ends of the edge pressing bracket 31 are mounted on the crossbeam 1 via vertical slides 32. The second driving device 33 is positioned between the plate support and the crossbeam 1. Driven by the second driving device 33, the edge pressing plate 30 is pressed downwards against the upper side of the product 5 to be sealed with corner tape.

[0057] How to use

[0058] When the corner sealing machine provided in this embodiment is in use, the tape roll is fixed on the tape mounting post 3, and the tape is pulled out by the first rotating wheel 4 and the second rotating wheel 10. The elastic fastener on the second rotating wheel 10 presses the tape tightly, exposing the end of the tape. When the product moves to the tape sealing station, the second fixing plate 13 is driven to move downward by the first driving device 29, and at the same time, the second pillar 28 drives the first edge pressing device 25 to press against one side of the corner of the product to be sealed. The second driving device 33 drives the second pressing device to press against the other side of the corner of the product 5 to be corner-applied with tape; the moving device drives the first fixing plate 12 to move downwards, and under the drive of the elastic element, the cutting blade 6 deflects away from the tape, the side of the product contacts the first rotating wheel 4, and the tape adheres to one side of the corner of the product. The belt drive device drives the base 2 to move on the crossbeam 1. As the base 2 slides forward on the crossbeam 1, the tape is continuously pulled out. The pre-pressing member 18 pre-presses the tape, and the compacting roller 7 compacts the tape. Figure 10 As shown, when the device moves to the very front of the product, the second fixing plate 13 is driven upward by the up-and-down moving device 17. The cutting head on the cutting blade 6 is deflected towards the side closer to the tape by the action of the first support column 14, cutting the tape, and the corner sealing machine resets. The corner sealing machine provided by this invention enables continuous application of tape to the corners of the product, and the tape is flat and compacted without wrinkles.

[0059] In addition, this embodiment also provides a packaging machine that uses the corner sealing machine described in the above embodiments. When in use, the corners of the product are continuously sealed with tape, and the tape is flat and compacted without wrinkles.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
