Description

Technical Field

[0001] This utility model particularly relates to an automatic sealing device for a carton conveyor line. Background Technology

[0002] In the traditional carton sealing process, manual operation is usually relied upon to fold the carton lids. However, manual folding has many problems: First, manual operation is inefficient and cannot meet the needs of large-scale production; second, the force and angle of manual folding are difficult to maintain consistently, easily leading to loose, uneven, or even deformed or damaged lids. This not only affects the aesthetics of the packaging but may also cause the contents of the carton to fall out during transportation due to insecure sealing, resulting in unnecessary losses. Furthermore, manual folding is labor-intensive, and prolonged work can easily lead to worker fatigue, further reducing sealing quality and efficiency. Therefore, developing a device that can automatically, efficiently, and reliably complete carton sealing is particularly important. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an automatic sealing device for a carton conveyor line.

[0004] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0005] An automatic sealing device for a carton conveyor line includes: folding mechanisms symmetrically arranged above a conveying mechanism, wherein the conveying mechanism transports cartons and the two lids of the cartons are in an opening position facing each other; each folding mechanism includes:

[0006] A fixed bracket is located above the conveying mechanism;

[0007] The guide rod is inclined and set on the fixed bracket, forming an acute angle with the upper end face of the carton;

[0008] A drive unit, fixed on a fixed bracket, is used to drive the guide rod to move along its axial direction;

[0009] The pressure bar is connected to the end of the guide bar and is parallel to the conveying direction of the conveying mechanism;

[0010] The drive device drives the guide rod to move the pressure rod along a preset trajectory. The pushing action of the pressure rod causes the two opening lids to come into contact with each other and close.

[0011] Preferably, there are two guide rods, which are rigidly connected by a fixing plate; the pressure rod is fixedly installed on the fixing plate; the output end of the driving device is connected to the fixing plate, and the two guide rods move synchronously by driving the fixing plate.

[0012] Preferably, a bushing is installed on the fixed bracket, and the guide rod is slidably inserted inside the bushing, with the inner wall of the bushing and the guide rod forming a sliding fit.

[0013] Preferably, the pressure bar includes an inclined section and a horizontal section connected in sequence. The inclined section is located at the feed end near the carton conveying direction and is inclined upward. When the carton is conveyed to the folding station, the inclined section first contacts the carton cover and guides it to press down gradually, and the horizontal section then completes the final pressing of the carton cover.

[0014] Preferably, the driving device is a driving cylinder.

[0015] Preferably, the inclined segment and the horizontal segment are integrally formed.

[0016] The beneficial effects of this utility model are:

[0017] This invention features a folding mechanism above the conveying mechanism. A guide rod is installed at an angle using a fixed bracket, forming an acute angle with the upper surface of the carton. A drive device precisely drives the guide rod to move axially, along with the pushing action of the pressure rod. This technology ensures consistency in force and angle during the sealing process, avoiding problems such as loose lid closure and deformation caused by inconsistent manual operation. This significantly improves sealing quality and reliability, increases production efficiency, and allows for adjustment of the pressure rod height via the drive device to accommodate cartons of different sizes, thus broadening its applicability.

[0027] An automatic sealing device for a carton conveyor line includes: folding mechanisms symmetrically arranged above a conveying mechanism 10, wherein the conveying mechanism 10 conveys a carton 20 and the two lids of the carton are in an opening position facing each other; each folding mechanism includes:

[0028] The fixed bracket 31 is located above the conveying mechanism 10;

[0029] The guide rod 32 is inclinedly mounted on the fixed bracket 31 and forms an acute angle with the upper end face of the carton 20;

[0030] The drive device 33 is fixed on the fixed bracket 31 and is used to drive the guide rod 32 to move along its axial direction;

[0031] The pressure rod 34 is connected to the end of the guide rod 32 and is parallel to the conveying direction of the conveying mechanism 10;

[0032] The driving device 33 drives the guide rod 32 to move the pressure rod 34 along a preset trajectory. The pushing action of the pressure rod 34 causes the two opening boxes to come into contact with each other and close.

[0033] Furthermore, two guide rods 32 are provided, and the two guide rods 32 are rigidly connected by a fixing plate 36; the pressure rod 34 is fixedly installed on the fixing plate 36; the output end of the driving device 33 is connected to the fixing plate 36, and drives the two guide rods 32 to move synchronously by driving the fixing plate 36.

[0034] Furthermore, a bushing 35 is installed on the fixed bracket 31, and the guide rod 32 is slidably inserted inside the bushing 35, with the inner wall of the bushing 35 forming a sliding fit with the guide rod 32.

[0035] Furthermore, the pressure bar 34 includes an inclined section 341 and a horizontal section 342 connected in sequence. The inclined section 341 is located near the feeding end of the carton 20 in the conveying direction and is inclined upward. When the carton 20 is conveyed to the folding station, the inclined section 341 first contacts the carton cover and guides it to be pressed down gradually. The horizontal section 342 then completes the final pressing of the carton cover.

[0036] Furthermore, the driving device 33 is a driving cylinder.

[0037] Furthermore, the inclined section 341 and the horizontal section 342 are integrally formed.

[0038] The working principle of this utility model is as follows:

[0039] Preparation of conveyor mechanism 10: Prepare the conveyor mechanism 10 for conveying cartons. The conveyor mechanism 10 can adopt common structures such as belt conveyors or roller conveyors. Leave enough space above the conveyor mechanism 10 to install the folding mechanism.

[0040] Fixed bracket installation: A mounting bracket can be installed on the conveying mechanism 10, and the fixed bracket can be fixed above the conveying mechanism 10 through the mounting bracket, or fixed brackets can be installed on both sides of the conveying mechanism 10, as long as the folding mechanism can cover the upper area of ​​the carton on the conveying mechanism 10.

[0041] Installation of the guide rod: The guide rod 32 is installed at an angle on the fixed bracket 31, ensuring that it forms an acute angle with the upper surface of the carton 20. An acute angle means that the angle between the guide rod 32 and the upper surface of the carton 20 is less than 90°. The main purpose of this design is to better guide the downward and closing action of the carton lid, ensuring a smooth sealing process.

[0042] Installation of drive unit 33: A drive cylinder can be selected to achieve this. The drive cylinder 33 is fixed on the fixed bracket 31 to ensure that its output end can be effectively connected to the fixed plate 36.

[0043] Installation of pressure bar 34: Connect pressure bar 34 to the end of guide bar 32 and adjust its position to be parallel to the conveying direction of conveying mechanism 10. The length and shape of pressure bar 34 can be selected according to the size of the carton to ensure effective contact and push of the carton lid.

[0044] The mounting of the fixing plate is optional: If a design with two guide rods 32 is adopted, the two guide rods 32 are rigidly connected by the fixing plate 36, and the pressure rod 34 is fixedly mounted on the fixing plate 36. At the same time, the output end of the drive cylinder 33 is connected to the fixing plate 36 to ensure that the two guide rods 32 can move synchronously.

[0045] The bushing can be installed as follows: the bushing 35 is installed on the fixed bracket 31, and the guide rod 32 is slidably inserted into the bushing 35 to ensure that the inner wall of the bushing 35 and the guide rod 32 form a good sliding fit.

[0046] The pressure bar can be designed in sections: If a sectioned pressure bar is used, the pressure bar 34 is divided into an inclined section 341 and a horizontal section 342, and connected and installed according to design requirements. Ensure that the inclined section 341 is located near the feed end of the carton 20 in the conveying direction and is inclined upwards. Preferably, the inclined section 341 and the horizontal section 342 are integrally formed.

[0047] Carton sealing process

[0048] like Figure 2 As shown, the carton is placed on the conveyor mechanism 10, with the two lids of the carton in an open, facing-to-facing state. When the carton reaches the lid-folding station, the drive cylinder 33 pushes the guide rod 32 to move axially. The guide rod 32 drives the pressure rod 34 to move downward. If a segmented pressure rod 34 is used, the inclined section 341 first contacts the lid. As the carton continues to be conveyed, the inclined section 341 gradually presses the lid down. Subsequently, the horizontal section 342 continues to act on the lid, completing the final pressing action of the lid. Driven by the guide rod 32, the pressure rod 34 pushes the two open, facing-to-facing lids to contact each other and close, as shown. Figure 3 As shown. Closure refers to the contact state where the two lids of the box reach a point where they prevent items inside the box from falling out, including but not limited to completely parallel contact, partial overlapping contact, or forming an angled contact. In the above technical solution, when the guide rod 32 drives the pressure rod 34 to a position where it can contact the lid, the guide rod stops moving, the pressure rod remains stationary, and the lid of the box achieves a closed state by passing the pressure rod during the conveying process.

[0049] Once the lid is closed, the carton is conveyed away from the folding station by the conveying mechanism 10, waiting for the next carton to enter the folding station (i.e., below the folding mechanism).

[0050] Traditional carton sealing technology suffers from low efficiency due to manual operation, while complex automated equipment is costly and lacks adaptability. This invention addresses this issue by incorporating a folding mechanism above the conveyor, using a fixed bracket to tilt the guide rod and create an acute angle with the top surface of the carton. A drive unit precisely moves the guide rod axially, and a pressure bar advances. This technology ensures consistent force and angle during sealing, preventing issues like loose closure and deformation caused by inconsistent manual operation. This significantly improves sealing quality and reliability, increases production efficiency, and allows for adjustment of the pressure bar height via the drive unit, accommodating cartons of different sizes and broadening its applicability.

[0051] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
