Description

Technical Field

[0001] This invention relates to the field of carton sealing machine technology, specifically to a carton sealing machine that assists in applying adhesive tape. Background Technology

[0002] Carton sealing machines are often used when sealing cartons. The carton sealing machine applies tape to the area of ​​the carton to be sealed. Corner sealing machines are specifically designed for sealing cartons with the sealing position on the side. When the sealing position is on the side of the carton, the tape needs to be bent into a right angle after being applied.

[0003] Existing corner sealing machines require precise control of the tape cutting length when sealing the sides of cartons. This length needs to match the side length of the carton, which places high demands on the precision of the sealing machine. If the tape is too long, its ends will exceed the length of the carton, resulting in insufficient tape flatness, affecting the appearance, and making the carton easy to be pulled open during subsequent transportation. If the tape is too short, it cannot completely cover the seal, resulting in part of the seal being exposed, thus affecting the sealing effect.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a carton sealing machine that assists in applying adhesive tape. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a carton sealing machine that assists in applying adhesive tape, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a carton sealing machine for assisting in the flattening of adhesive tape, comprising a conveyor belt, a tape dispensing assembly, and a tape flattening assembly. Support plates are provided on both sides of the conveyor belt, and the tape dispensing assembly and the tape flattening assembly are sequentially fixed to the sides of the support plates. The tape flattening assembly includes a support frame, an electric push rod, a torsion spring shaft, a spring box, a connecting rod, a pasting roller, and a cutting blade. The electric push rod is fixed to the top of the support frame, and a torsion spring shaft is connected to the bottom of the electric push rod. A spring box is connected to the end of the torsion spring shaft, and a connecting rod is slidably connected inside the spring box. A pasting roller is rotatably connected to the bottom of the connecting rod near the tape dispensing assembly. A cutting blade is fixed to the bottom surface of the connecting rod.

[0007] Furthermore, the surface of the conveyor belt is equidistantly distributed with partitions, and cardboard boxes are placed between the partitions.

[0008] Furthermore, the tape dispensing assembly includes a side mounting plate, a pre-pressure roller, a tape box, and a flat pressure roller. The side of the side mounting plate is rotatably connected to the pre-pressure roller, and a tape box is provided on one side of the pre-pressure roller. A flat pressure roller is provided on one side of the tape box.

[0009] Furthermore, the tape box is provided with a tape assembly inside, the tape assembly includes a non-stick layer, a cardboard layer and an adhesive layer, the non-stick layer is provided in two layers, with a cardboard layer between the non-stick layers, and an adhesive layer is provided on the bottom surface of the lower non-stick layer.

[0010] Furthermore, the cutting blade has a T-shaped structure, and the height of the cutting blade is lower than the bottom height of the bonding roller.

[0011] Furthermore, the tape flattening assembly also includes a side panel and a semi-circular protrusion. The side panel is fixed to the top surface of the support plate, and a semi-circular protrusion is provided on the upper part of the outer side surface of the side panel.

[0012] Furthermore, the tape-applying assembly also includes horizontal telescopic plates, which are fixed to the side of the connecting rod, and the spacing between the horizontal telescopic plates is adapted to the length of the carton body.

[0013] Furthermore, the tape-applying assembly also includes a straight cutter, which is positioned above the horizontal telescopic applicator.

[0014] Furthermore, the straight cutting blade and the trimming blade are staggered vertically, and the straight cutting blade is fixedly connected to the connecting rod.

[0015] Furthermore, the tape flattening assembly also includes a vertical lifting plate, which is provided on one side of the straight cutter and is located directly above the horizontal telescopic plate.

[0016] This invention provides a carton sealing machine that assists in applying adhesive tape, and has the following beneficial effects:

[0017] This carton sealing machine with auxiliary tape application can perform T-shaped cuts, right-angle bends, and horizontal bends at both ends of the tape assembly to flatten it against the sides of the carton body as the tape roller descends and rolls on two adjacent vertical surfaces of the carton body. It also performs secondary straight cuts on the horizontal portion of the tape assembly at the gap between carton bodies and flattening of the cut ends. This results in a smooth and appropriately sized tape application at the carton sealing position after sealing. Furthermore, compared to existing carton sealing machines that require precise calculations of bonding timing and tape cutting length, this auxiliary tape application sealing machine has a simpler and more effective structure.

[0024] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0025] like Figures 1-5As shown, the present invention provides a technical solution: a carton sealing machine for assisting in applying adhesive tape, comprising a conveyor belt 1, a tape dispensing assembly 3, and a tape applying assembly 4. Support plates 2 are provided on both sides of the conveyor belt 1. The tape dispensing assembly 3 and the tape applying assembly 4 are sequentially fixed to the sides of the support plates 2. The tape applying assembly 4 includes a support frame 401, an electric push rod 402, a torsion spring shaft 403, a spring box 404, a connecting rod 405, a pasting roller 406, and a cutting blade 407. The electric push rod 402 is fixed to the top of the support frame 401, and the torsion spring shaft 403 is connected to the bottom of the electric push rod 402. The spring box 404 is connected to the end of the torsion spring shaft 403. The connecting rod 405 is slidably connected inside the spring box 404, and the pasting roller 406 is rotatably connected to the bottom of the connecting rod 405. The cutting blade 407 is fixed to the bottom surface of the connecting rod 405 near the tape dispensing assembly 3. The tape applying assembly 4 also includes a side pasting plate 408 and... A semi-circular protrusion 409 is provided. A side panel 408 is fixed to the top surface of the support plate 2, and a semi-circular protrusion 409 is provided on the upper outer side surface of the side panel 408. The tape-applying assembly 4 also includes a horizontal telescopic panel 410. A horizontal telescopic panel 410 is fixed to the side of the connecting rod 405, and the spacing between the horizontal telescopic panels 410 is adapted to the length of the carton body 6. The tape-applying assembly 4 also includes a straight cutter 411. A horizontal telescopic panel 410 is provided above the horizontal telescopic panel 410. A straight cutter 411 is provided, which is staggered with the cutting blade 407. The straight cutter 411 is fixedly connected to the connecting rod 405. The tape flattening assembly 4 also includes a vertical lifting plate 412. The vertical lifting plate 412 is provided on one side of the straight cutter 411 and is located directly above the horizontal telescopic plate 410. The cutting blade 407 has a T-shaped structure and the height of the cutting blade 407 is lower than the bottom height of the tape roller 406.

[0026] The specific operation is as follows: the tape assembly 7 is applied in a straight line without interruption to the corner sealing position of the carton body 6. When the carton body 6 reaches the side panel 408, the conveying is paused. At this time, the electric push rod 402 extends, causing the bonding roller 406 to descend. The bonding roller 406 first applies to the upper surface of the carton body 6 and rotates under pressure via the torsion spring shaft 403, rolling towards the tape assembly 7 until the bonding roller 406 exceeds the side of the carton body 6. At this time, the bonding roller 406 resets via the torsion spring shaft 403 and continues to apply to the carton body via the electric push rod 402. As the carton body 6 rolls downwards from the side, the pasting roller 406 is attached to the upper surface of the carton body 6 while the cutting blade 407 has already cut the tape assembly 7 at the gap between the carton bodies 6. The cutting blade 407 has a T-shaped structure and cuts a T-shaped cut in the middle of the tape assembly 7 at the gap. Thus, the tape assembly 7 that is flatly attached to the upper surface of the carton body 6 remains unchanged. When the pasting roller 406 is attached to the side of the carton body 6 and rolls downwards, only the tape assembly 7 on the surface of the carton body 6 at the position of the side pasting plate 408 is bent and attached to the side of the carton body 6.

[0027] Next, the laminating roller 406 continues to descend, and during the descent, it extends and retracts horizontally along the semi-circular protrusion 409 on the outer side of the side panel 408. The end of the connecting rod 405 is slidably connected to the inside of the spring box 404 and is elastic through the spring inside the spring box 404. The connecting rod 405 causes the laminating roller 406 to roll along the semi-circular protrusion 409 and extend and retract horizontally. This causes the horizontal extension panel 410 to extend and retract horizontally, thus passing over the tape assembly 7 at the gap between the upper surfaces of the carton bodies 6 and smoothing the already bent end of the tape assembly 7 so that it is flat against the side of the carton body 6.

[0028] Then the laminating roller 406 continues to descend. During the descent, the straight cutter 411 cuts the part of the tape assembly 7 that is still connected at the gap between the carton bodies 6. The vertical lifting laminating plate 412 follows closely and smooths the cut end of the tape assembly 7 downward so that it is attached to the side of the carton body 6.

[0029] Based on the above description, when the bonding roller 406 rolls downwards on two adjacent vertical surfaces of the carton body 6, it can sequentially perform T-shaped cuts on the tape assembly 7; right-angle bends on the tape assembly 7; horizontal bends at both ends of the bent portion of the tape assembly 7 to flatly adhere to both sides of the carton body 6; secondary straight cuts on the horizontal portion of the tape assembly 7 at the gap between the carton bodies 6; and flat application of the cut end face of the tape assembly 7. As a result, after sealing, the tape assembly 7 at the sealing position of the carton body 6 is flat and of appropriate length. At the same time, compared with existing carton sealing machines that require precise calculation of bonding timing and tape cutting length, this auxiliary tape-applying sealing machine has a simpler and more effective structure.

[0030] like Figures 1-5 As shown, partitions 5 are evenly distributed on the surface of the conveyor belt 1, and cardboard box bodies 6 are placed between the partitions 5.

[0031] The carton body 6 is placed between the partitions 5 and transported by the conveyor belt 1 to achieve a streamlined sealing operation, wherein the corner sealing positions of the carton body 6 are all on the same side.

[0032] like Figures 1-5 As shown, the tape dispensing assembly 3 includes a side mounting plate 301, a pre-pressure roller 302, a tape box 303, and a flat pressure roller 304. The side of the side mounting plate 301 is rotatably connected to the pre-pressure roller 302, and a tape box 303 is provided on one side of the pre-pressure roller 302. A flat pressure roller 304 is provided on one side of the tape box 303.

[0033] The specific operation is as follows: When the carton body 6 is being transported, it is first pressed onto the top of the carton body 6 by the pre-pressure roller 302 to ensure that the lid is closed. Then, the carton body 6 passes through the tape box 303, which continuously releases tape components 7 to adhere to the sealing position at the corner of the carton body 6. Then, the flat pressure roller 304 applies pressure to the upper surface of the tape components 7 as they are being released, so that the tape components 7 can be tightly attached to the sealing position. After the tape components 7 are flat, some parts will extend beyond the side of the carton body 6, and the tape components 7 are released continuously. During the release process, there is no need to use a cutting device to cut the tape components 7 one-to-one with the carton body 6.

[0034] like Figures 1-5 As shown, the tape box 303 is provided with a tape assembly 7 inside. The tape assembly 7 includes a non-stick layer 701, a cardboard layer 702 and an adhesive layer 703. There are two non-stick layers 701, with a cardboard layer 702 between the non-stick layers 701. The bottom surface of the lower non-stick layer 701 is provided with an adhesive layer 703.

[0035] The non-adhesive layer 701 is the exposed surface of the existing tape that is not affected by adhesive. The hard paper layer 702 is a relatively stiff paper structure that, without affecting the roll formation of the tape assembly 7, prevents the tape assembly 7 from becoming too soft after it is released. It is used to support the part of the tape assembly 7 that extends beyond the side of the carton body 6 and prevent the extended part from collapsing.

[0036] In summary, when using this carton sealing machine with auxiliary tape application, the carton body 6 is first placed between the partitions 5 and transported by the conveyor belt 1 to achieve a streamlined sealing operation. The corner sealing positions of the carton body 6 are all on the same side. During transport, the carton body 6 is first pressed by the pre-pressure roller 302 to ensure that the lid is closed. Then, the carton body 6 passes through the tape box 303, which continuously releases tape components 7 to adhere to the sealing positions at the corners of the carton body 6. The flat pressure roller 304 then applies pressure to the upper surface of the tape components 7 as they are released, so that the tape components 7 can be tightly attached to the sealing position. After being flattened, some parts of the tape components 7 will extend beyond the side of the carton body 6, and the tape components 7 are released continuously.

[0037] The tape assembly 7 is applied in a straight line without interruption to the corner sealing position of the carton body 6. When the carton body 6 reaches the side panel 408, the conveying is paused. At this time, the electric push rod 402 extends, causing the pasting roller 406 to descend. The pasting roller 406 first applies to the upper surface of the carton body 6 and rotates under pressure via the torsion spring shaft 403, rolling towards the tape assembly 7 until the pasting roller 406 exceeds the side of the carton body 6. At this time, the pasting roller 406 returns to its original position via the torsion spring shaft 403 and continues to apply to the side of the carton body 6 via the electric push rod 402. As the tape rolls downwards, the laminating roller 406 adheres to the upper surface of the carton body 6 while the cutting blade 407 has already cut the tape assembly 7 at the gap between the carton bodies 6. The cutting blade 407 has a T-shaped structure and cuts a T-shaped slit in the middle of the tape assembly 7 at the gap. Thus, the tape assembly 7 that is flatly attached to the upper surface of the carton body 6 remains unchanged. However, when the laminating roller 406 is attached to the side of the carton body 6 and rolls downwards, only the tape assembly 7 on the surface of the carton body 6 at the location of the side panel 408 is bent and attached to the side of the carton body 6.

[0038] Next, the laminating roller 406 continues to descend, and during the descent, it extends and retracts horizontally along the semi-circular protrusion 409 on the outer side of the side panel 408. The end of the connecting rod 405 is slidably connected to the inside of the spring box 404 and is elastic through the spring inside the spring box 404. The connecting rod 405 causes the laminating roller 406 to roll along the semi-circular protrusion 409 and extend and retract horizontally. This causes the horizontal extension panel 410 to extend and retract horizontally, thus passing over the tape assembly 7 at the gap between the upper surfaces of the carton bodies 6 and smoothing the already bent end of the tape assembly 7 so that it is flat against the side of the carton body 6.

[0039] Then the laminating roller 406 continues to descend. During the descent, the straight cutter 411 cuts the part of the tape assembly 7 that is still connected in the gap between the carton bodies 6. The vertical lifting laminating plate 412 follows closely and smooths the cut end of the tape assembly 7 downward, so that it is attached to the side of the carton body 6.
