Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, and more specifically, relates to an automated box sealing device. Background Technology

[0002] Chip packaging typically refers to packing chips according to certain specifications, quantities, or methods to facilitate subsequent transportation, storage, and sales. After the chips are placed in the packaging box, the box needs to be sealed and labeled. Currently, sealing and labeling are mostly done manually, which is inefficient and results in low quality.

[0003] To address the aforementioned issues, corresponding improvements have been made. For example, Chinese patent application number CN202410678960.7, published on August 2, 2024, discloses a cigarette box flipping, sealing, labeling, palletizing, and transferring device. It includes a flipping mechanism, a pushing mechanism, a conveyor, and an adhesive mechanism. The flipping mechanism is used to lay the cigarette box down so that the opening requiring tape faces to the side. The pushing mechanism is located on one side of the flipping mechanism and is used to push the fallen cigarette box out in a direction perpendicular to the opening. The conveyor is used to receive the cigarette box pushed out by the pushing mechanism and continue to transport it forward. The adhesive mechanism is symmetrically installed on both sides of the conveyor and is used to apply tape to the upper and lower openings of the cigarette box. The drawback of this patent is that although it achieves automated operation of the entire process, the sealing effect is poor.

[0004] For example, Chinese patent application number CN202123239440.7, published on June 7, 2022, discloses a carton sealing and labeling integrated machine, including a frame, a conveyor roller group, and support legs connected to the bottom of the frame. A sealing mechanism and a labeling mechanism are connected to the top of the frame. A pressing mechanism is located on the side of the sealing mechanism away from the labeling mechanism, and an adjustment mechanism for controlling the height of the pressing mechanism is connected to the frame. The pressing mechanism includes a fixed base, with an inclined roller installed between two sets of fixed bases. A pressing roller is located on the side of the inclined roller closer to the sealing mechanism, and a cleaning mechanism for cleaning the top of the carton is located on the side of the pressing roller away from the inclined roller. The drawback of this patent is its complex structure and high cost. Utility Model Content

The sealing unit includes two opposing limiting plates forming a clamping space between them. A frame is arranged above the clamping space, and opposing folding arms are arranged on the frame. The folding arms are used to fold two opposing side walls of the top of the carton inward by 90 degrees. The frame is also equipped with a push plate and a baffle, which are arranged opposite each other and are used to fold the other two opposing side walls of the top of the carton inward by 90 degrees.

[0010] Furthermore, the frame includes a fixed block and a crossbeam. One end of the crossbeam is connected to the fixed block, and the other end is rotatably equipped with a push plate. A baffle is provided on the crossbeam at a position opposite to the push plate. The height of the baffle is less than the height of the housing, and the baffle is arc-shaped. A folding arm is provided on the lower part of the pressure block.

[0011] Furthermore, a pressure plate is also provided on the frame, with one end of the pressure plate connected to a baffle.

[0012] Furthermore, a glue-applying mechanism for applying adhesive tape to the top of the box is provided between the frame and the rotating device. The glue-applying mechanism includes a glue-dispensing wheel and a rolling wheel. Adhesive tape is provided on the glue-dispensing wheel and the adhesive tape on the glue-dispensing wheel is connected to the rolling wheel. The rolling wheel abuts against the box to perform the glue-applying action on the top of the box. A cutting blade is provided on one side of the rolling wheel.

[0013] Furthermore, the adhesive device includes four adhesive units arranged in a rectangular frame; the four adhesive units are used to adhesively adhere the four sides of the packaging box.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) This utility model automates the sealing process of the top of the box, which greatly improves the sealing efficiency and reduces the labor cost. At the same time, the sealing device can fold the four side walls of the top surface of the box through the push plate, baffle and two folding arms. There is no need to use complex mechanical parts or expensive automated parts to achieve folding, which ensures good folding effect and saves costs. The entire equipment has a simple structure and each device is independent and does not interfere with each other, which effectively ensures the stability and efficiency of the entire sealing process.

[0020] (2) In this utility model, the frame serves as the basic framework of the entire packaging device, possessing a certain stability and strength; the push plate, baffle, and folding arm are all integrated on the frame, making reasonable use of the equipment space, resulting in a small area occupied by the entire packaging device, easy installation, and less susceptible to the influence of limited space factors; and the setting of the pressure plate enables the box to be pressed during the folding process, making it easy to fold.

[0021] (3) After the packaging device folds the top of the box, the glue applicator will apply glue to the folded surface for the first time, which reduces the workload of the subsequent glue applicator and improves the glue applicator efficiency; it also makes the folded surface have a certain degree of sealing after the first glue application, so that the folded surface is not easy to spread out when it passes through the subsequent rotating device, thus ensuring stability.

[0022] (4) The adhesive device of this utility model sets four adhesive units to simultaneously perform adhesive operations on the four sides of the box, thereby improving work efficiency; the adhesive device places the tape roll on the unwinding mechanism, stretches the tape to the adhesive mechanism, the adhesive mechanism adheres the tape to the side of the box, and after the adhesive is completed, the cutting mechanism cuts the tape. The whole process is highly automated, has high adhesive efficiency and standardization, and improves the aesthetics of the adhesive.

[0023] (5) The rotating device of this utility model has a simple structure. The rotating table is connected to the driving component so that the rotating table can realize the corresponding movement or rotation function, and the integration is high. Furthermore, the mechanical claw is used to transport the box, ensuring the stability of the transport process. The setting of the stop plate effectively prevents the box from falling off the rotating table during rotation, ensuring the safety and stability of the rotation process. Attached Figure Description

[0035] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, an automated carton sealing device includes a sealing device 1, a rotating device 2, and an adhesive device 3 arranged sequentially. Since the carton is open at the top before entering the sealing device 1, the sealing device 1 needs to fold and seal the carton. The rotating device 2 is used to rotate the carton after passing through the sealing device 1, aligning the area to be adhesiveped with the adhesive device 3. The adhesive device 3 applies tape to the folded carton, further sealing it. The carton is then sealed by the adhesive device 3, completing the entire sealing process.

[0037] Specifically, in this embodiment, the packaging device 1 includes two opposing limiting plates 15, forming a clamping space between the two limiting plates 15. The clamping space is used to accommodate a box with a top opening and serves as a worktable for folding the top of the box. A frame is provided above the clamping space, and folding arms 14 are provided on the frame, which are arranged opposite to each other. The folding arms 14 are used to fold the two opposite side walls of the top of the box inward by 90 degrees. A push plate 11 and a baffle 12 are also provided on the frame, which are arranged opposite to each other and are used to fold the other two opposite side walls of the top of the box inward by 90 degrees. In this embodiment, the two limiting plates 15 are arranged horizontally. The two sides of the top of the box that are parallel to the two limiting plates 15 within the clamping space are called the long sides, and the other two sides are called the short sides. The push plate 11 and the baffle 12 are used to fold the two short sides of the top of the box inward by 90 degrees, and the two folding arms are used to fold the two long sides of the top of the box inward by 90 degrees. The specific folding process is as follows: When the box with the top open (initial state) enters the clamping space and moves to the operating position within the clamping space, one of the short sides of the box contacts the baffle 12, and during the movement, the baffle 12 folds the short side inward by 90 degrees. When the operating position is reached, the push plate 11 folds the other short side inward by 90 degrees. Subsequently, the two folding arms 14 fold the two long sides of the box inward by 90 degrees, completing the inward folding of the four sides of the top of the box. The initial state is: the long side of the top is parallel to the limiting plate 15; and it is worth noting that the push plate 11 and the two folding arms 14 move under the drive of the driving component to complete the inward folding of 90 degrees. How to complete the folding of 90 degrees is a relatively mature technology in the prior art, and the existing technology can be used. Therefore, this application will not elaborate on its implementation principle and structure.

[0038] This invention automates the sealing process at the top of the box, greatly improving sealing efficiency and reducing labor costs. Simultaneously, the sealing device 1 folds the four sides of the box top surface using a push plate 11, a baffle 12, and two folding arms 14, eliminating the need for complex mechanical or expensive automated components, ensuring good folding results while saving costs. The entire device has a simple structure, with each component independent and non-interfering with the others, effectively ensuring the stability and efficiency of the entire sealing process.

[0039] like Figure 3As shown, in one embodiment, the frame includes a fixed block and a crossbeam. One end of the crossbeam is connected to the fixed block, and the other end is rotatably equipped with a push plate 11. That is, the push plate 11 is set at the end of the crossbeam by a driving component. The push plate 11 can apply an external force to the short side of the box under the action of the driving component, thereby completing the folding of the short side of the box inward by 90 degrees. A baffle 12 is provided on the crossbeam opposite to the push plate 11. The height of the baffle 12 is less than the height of the box, and the baffle 12 is arc-shaped. Because the height of the baffle 12 is less than the height of the box, when the box contacts the baffle 12 and continues to move forward, the baffle 12 provides an obstruction force to the short side of the box, causing the short side to fold inward by 90 degrees. The arc shape serves as a guide to ensure the folding effect. A folding arm 14 is provided opposite to the lower part of the pressure block. In this embodiment, the frame serves as the basic framework of the entire packaging device 1, providing a certain degree of stability and strength. The push plate 11, baffle 12, and folding arm 14 are all integrated on the frame, making reasonable use of the equipment space. This results in a small area occupied by the entire packaging device, making it easy to install and less susceptible to the influence of limited space factors.

[0040] In one embodiment, the frame is further provided with a pressure plate 13, one end of which is connected to the baffle 12. The pressure plate 13 serves two purposes: first, it allows the box to be pressed during the folding process, facilitating folding; second, it prevents the short side folded by the baffle 12 from returning to its original state, thus resisting the folding of the short side and ensuring the folding effect.

[0041] In one embodiment, a glue-applying mechanism for applying adhesive tape to the top of the box is further provided between the frame and the rotating device 2. The glue-applying mechanism includes a glue-dispensing wheel and a rolling wheel. Adhesive tape is disposed on the glue-dispensing wheel and connected to the rolling wheel. The rolling wheel abuts against the box to apply adhesive to the top of the box. A cutting blade is provided on one side of the rolling wheel. In this embodiment, it should be noted that this glue-applying mechanism is different from the subsequent adhesive device 3 because the adhesive application locations are different. This glue-applying mechanism folds the two long sides of the box inward at a 90-degree angle to form a crease and applies adhesive tape to this crease. The subsequent adhesive device 3 applies adhesive tape to the creases formed by folding the two short sides of the box inward at a 90-degree angle. This glue-applying mechanism reduces the workload of the subsequent adhesive device 3, improving glue-applying efficiency. It also ensures that the folded surface has a certain degree of sealing after one application of adhesive, preventing it from unraveling when passing through the rotating device 2, thus ensuring stability.

[0042] Specifically, because the limiting plate 15 has a certain length, the glue applicator is set above the limiting plate 15. After all four sides of the top of the box are folded, it moves to the position of the glue applicator within the clamping space, making reasonable use of the equipment space and minimizing the space occupied by the entire equipment. When it moves to the position of the glue applicator, the glue-dispensing roller and the rolling roller start working. The glue-dispensing roller continuously feeds the tape onto the rolling roller. The tape on the rolling roller is adhered to the crease of the box by the rolling roller. After the crease is completely glued, the tape is cut by the cutting blade to complete the full gluing operation of the crease.

[0043] like Figure 5 As shown, in one embodiment, the adhesive device 3 includes four adhesive units arranged in a rectangular frame. The four adhesive units are used to adhesively adhere to the four sides of the box (here, the four sides refer to the two short sides at the top and the two short sides at the bottom opposite the top), simultaneously performing adhesive operations on the four sides of the box to improve work efficiency. It is worth noting that since the adhesive device 3 folds the short sides of the box, the box after passing through the sealing device 1 needs to be rotated before entering the adhesive device 3. Initially, the long side of the top of the box is parallel to the limiting plate 15; it needs to be rotated until the long side of the top of the box is perpendicular to the limiting plate 15, so that the short side of the top of the box faces the adhesive unit, facilitating the application of adhesive tape to the short side.

[0044] The adhesive bonding unit includes a fixing plate, on which an unwinding mechanism 31, a cutting mechanism 32, and an adhesive bonding mechanism 33 are mounted. The unwinding mechanism 31 is located on one side of the adhesive bonding mechanism 33, and the cutting mechanism 32 is located above or below the adhesive bonding mechanism 33. In this embodiment, the fixing plate serves as the main frame of the adhesive bonding unit, and all other components are integrated onto the fixing plate for easy installation and management. Adhesive tape wound into a roll is mounted on the unwinding mechanism 31. The tape stretched from the roll passes through the unwinding mechanism 31 and extends onto the adhesive bonding mechanism 33. The cutting mechanism 32 cuts the tape through extension and retraction. The entire process is highly automated, efficient, and standardized, improving the aesthetics of the adhesive bonding.

[0045] Preferably, in this embodiment, the adhesive unit further includes a tensioning mechanism, which is disposed on the fixed plate and located between the unwinding mechanism 31 and the adhesive mechanism 33. The tensioning mechanism is used to detect whether the pulled-out tape is under tension, thereby assisting in adjusting the tape unwinding speed and preventing the tape from becoming too long and sagging due to excessive unwinding, which would affect the adhesive effect. It is worth noting that the unwinding mechanism 31, the cutting mechanism 32, the adhesive mechanism 33, and the tensioning mechanism in this application can all be implemented using existing components; therefore, their implementation principles and structures will not be described in detail in this application.

[0046] In one embodiment, the rotating device 2 includes a rotating platform, which is connected to a driving component to enable the movement and rotation of the platform. Movement of the platform refers to its movement to the end of the limiting plate 12, allowing the box with its top folded into place, and then moving the box to the working position of the adhesive device 3. Rotation of the platform refers to rotating the short side of the box to be adhesiveped to align with the working position of the adhesive device 3, facilitating the adhesive application. The connection between components and the driving component to enable movement and rotation is common in the prior art; therefore, its implementation principle and structure will not be described in detail here. Furthermore, a mechanical gripper is provided above the rotating platform. This gripper feeds the box from the rotating platform into the adhesive device 3, completing the transfer of the box. The mechanical gripper can firmly grasp the box, preventing it from easily falling off during transport. Preferably, a stop plate is provided on the side of the rotating table parallel to the feeding direction of the mechanical claw. The stop plate effectively prevents the box from falling off the rotating table during rotation, ensuring the safety and stability of the rotation process.

[0047] In one implementation, such as Figure 4As shown, the automatic box sealing equipment also includes a marking device 5, which is located after the adhesive device 3. The marking device 5 and the adhesive device 3 are connected by a conveying device 4 to transport the box. The marking device 5 is used to affix labels to the box (referred to as packaging box 55) after the adhesive application is completed. Specifically, the marking device 5 includes a marking platform 51, which is used to mark the packaging box 5. Specifically, in this embodiment, the marking platform 51 has a certain length and is equipped with several rollers. The rotation of the rollers drives the packaging box 55 to move on the marking platform 51. A first marking device 52 and a second marking device 54 are sequentially arranged on one side of the marking platform 51, and a positioning device is provided between the first marking device 52 and the second marking device 54. Both the first marking device 52 and the second marking device 54 are used to mark the packaging box 55 on the marking platform 51. The positioning device allows for area positioning of the packaging box 55 to determine whether the marked area meets the requirements. Specifically, its working principle is as follows: When the packaging box 55 moves to the position of the positioning device on the marking platform 51, the positioning device positions the packaging box 55, determining its position and marking area. If the requirements are met, both marking devices operate; if the requirements are not met, the position of the packaging box 55 is adjusted to meet the marking requirements. It is worth noting that the first marking device 52 and the second marking device 54 can perform marking operations on the packaging box 55 simultaneously or sequentially, depending on the situation. In this embodiment, sequential marking is performed. After the first marking device 52 completes marking, the second marking device 54 then performs marking. This operation is easy to control, clear, and avoids confusion, ensuring work quality.

[0048] Preferably, a monitoring mechanism 53 is provided on the second marking device 54. The monitoring device 53 includes a camera, which is electrically connected to the controller. The camera faces the location where the labels are stored in the second marking device 54. The setting of the monitoring device 53 facilitates the verification of the labels, ensuring that the labels are correct and thus guaranteeing the accuracy of the labeling process. In addition, it can also monitor the remaining labels in real time. When the labels are about to run out, a signal is sent to the controller, which provides the staff with timely label replacement to complete the label replenishment.

[0049] The examples described herein are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the design concept of the present invention shall fall within the protection scope of the present invention.
