[0050] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0051] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0052] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0053] The present disclosure provides a sealing device, which is combined with Figures 1 to 8 The sealing device according to the embodiment of the present disclosure is described.

[0054] In the embodiments of the present disclosure, Figures 1 to 4 As shown, the sealing device includes a conveying mechanism 10 , an attaching mechanism 20 and a driving mechanism 30 .

[0055] The conveying mechanism 10 has a bearing surface for bearing and conveying materials, and the materials include a target box 70 and a sealing sticker 80 attached to the target box 70. The attaching mechanism 20 is arranged above the conveying mechanism 10, and the attaching mechanism 20 has a first roller 210 and a second roller 220 arranged at an angle, the first roller 210 is used to contact the first surface 71 of the target box 70 so that the sealing sticker 80 is attached to the first surface 71, and the second roller 220 is used to contact the second surface 72 of the target box 70 so that the sealing sticker 80 is attached to the second surface 72. The driving mechanism 30 is connected to the attaching mechanism 20, and the attaching mechanism 20 is operated by the driving mechanism 30 to make the sealing sticker 80 fit with the target box 70, and the first surface 71 and the second surface 72 of the target box 70 are not coplanar.

[0056] The conveying mechanism 10 includes a belt conveyor, a roller conveyor, etc. For example, the conveying mechanism 10 is a belt conveyor, which includes a conveyor belt having a bearing surface, and the conveyor belt is used to carry and convey materials. The materials include a target box 70 and a sealing sticker 80 attached to the target box 70. The sealing sticker 80 seals and decorates the target box 70. The conveying mechanism 10 is used to convey the target box 70 with the sealing sticker 80 attached to the target position, and the conveyor belt stops rotating at the target position.

[0057] The shape of the target box 70 can be a rectangle, a square, a polygon, etc. The target box 70 can be a packaging box, a color box, a drawer box, a top and bottom cover box, or a polygonal box. Taking the target box 70 as a color box as an example, the target box 70 has multiple surfaces, and the top surface of the target box 70 is defined as the first surface 71, and the four sides intersecting the first surface 71 are respectively the second surface 72, the third surface 73, the fourth surface and the fifth surface. The second surface 72 is opposite to the third surface 73, and the fourth surface is opposite to the fifth surface. In the case of sealing the target box 70 by a sealing sticker 80, a part of the sealing sticker 80 is pre-attached to the first surface 71, and another part of the sealing sticker 80 is pre-attached to the second surface 72. It can be understood that the first surface 71 and the second surface 72 are separable before they are not sealed.

[0058] The attaching mechanism 20 is disposed above the conveyor belt, and includes a first roller 210 and a second roller 220 for rolling the sealing sticker 80, and the first roller 210 and the second roller 220 are arranged at an angle. For example, the axis direction of the first roller 210 is perpendicular to the axis direction of the second roller 220. The first roller 210 can move in the vertical direction to approach or move away from the first surface 71 of the target box 70, and the second roller 220 can move in the horizontal direction to approach or move away from the second surface 72 of the target box 70. Optionally, the second roller 220 can also move in the vertical direction to adjust the height range of the contact area between the second roller 220 and the second surface 72.

[0059] The driving mechanism 30 is connected to the attaching mechanism 20, and is used to drive the attaching mechanism 20 to move in the rolling direction, so that when the first roller 210 moves in the rolling direction, the first part of the sealing sticker 80 is compacted and pressed against the first surface 71, so that the first part of the sealing sticker 80 is firmly attached to the first surface 71; when the second roller 220 moves in the rolling direction, the second part of the sealing sticker 80 is compacted and pressed against the second surface 72, so that the second part of the sealing sticker 80 is firmly attached to the second surface 72. The sealing sticker 80 consists of a first part and a second part.

[0060] Compared with rolling the sealing sticker 80 manually, rolling the first surface 71 and the second surface 72 simultaneously by the first roller 210 and the second roller 220 can effectively ensure the firmness of the sealing sticker 80 in contact with the first surface 71 and the second surface 72, and effectively avoid the problem of warping in the edge area of ​​the sealing sticker 80; in addition, the sealing efficiency can be effectively improved.

[0061] The rolling direction is defined as the first direction, and the driving mechanism 30 can move along the first direction to drive the first roller 210 and the second roller 220 to synchronously roll the first surface 71 and the second surface 72, so that the sealing label 80 can be firmly attached to the first surface 71 and the second surface 72. The conveying direction of the conveying mechanism 10 is defined as the second direction, and the vertical direction is defined as the third direction. The first direction, the second direction and the third direction intersect each other.

[0062] The working process of the sealing device is described below.

[0063] The conveying mechanism 10 conveys the material along the conveying direction, and the target box 70 to be rolled is conveyed to the target position. The target position refers to the position where the target box 70 stops moving before rolling. At the target position, the target box 70 is located directly below or in the vicinity of the first roller 210 and the second roller 220, and the first roller 210 and the second roller 220 can move or move to contact with the target box 70. In addition, the target position corresponds to the position of the clamping mechanism 40 described below, and at the target position, the clamping mechanism 40 can clamp the target box 70. At the target position, the first roller 210 moves along the third direction to contact with the first surface 71, and the first roller 210 can contact with the sealing sticker 80 at the first surface 71; the second roller 220 moves along the second direction to contact with the second surface 72, and the second roller 220 can contact with the sealing sticker 80 at the second surface 72.

[0064] After the first roller 210 contacts the first surface 71 and the second roller 220 contacts the second surface 72, the driving mechanism 30 drives the attaching mechanism 20 to move along the first direction. During the movement of the first roller 210 along the first direction, the first part of the sealing sticker 80 is closely attached to the first surface 71 with the rotational movement and linear movement of the first roller 210; during the movement of the second roller 220 along the first direction, the second part of the sealing sticker 80 is closely attached to the second surface 72 with the rotational movement and linear movement of the second roller 220. There is no specific limitation on the movement stroke of the driving mechanism 30 along the first direction, and it is sufficient to ensure that the first part and the second part of the sealing sticker 80 can be completely rolled.

[0065] After rolling is completed, the first roller 210 moves along the third direction to separate from the first surface 71, and the second roller 220 moves along the second direction to separate from the second surface 72. Afterwards, the conveying mechanism 10 conveys the rolled material to the tail end of the conveyor belt. According to the above operation steps, the sealing operation of multiple target boxes 70 is realized in sequence, which not only ensures the sealing quality, but also helps to improve the sealing efficiency.

[0066] In this embodiment, the conveying mechanism 10 is used to convey the target box 70 with the sealing sticker 80 attached thereto, the target box 70 having a first surface 71 and a second surface 72 intersecting each other, the attaching mechanism 20 is used to make the first roller 210 contact the sealing sticker 80 at the first surface 71, and the second roller 220 contact the sealing sticker 80 at the second surface 72, the driving mechanism 30 drives the first roller 210 and the second roller 220 to move along the rolling direction, so that the sealing sticker 80 is closely attached to the first surface 71 and the second surface 72, and the first surface 71 and the second surface 72 are closely connected through the sealing sticker 80, which is beneficial to improving the sealing quality and the sealing efficiency. In addition, the consistency and stability of the pressing are ensured by the attaching mechanism 20, and the close attachment of the first surface 71 and the second surface 72 after rolling is ensured, which can effectively prevent the sealing sticker 80 from warping and ensure the firmness of the connection between the first surface 71 and the second surface 72.

[0067] In the embodiments of the present disclosure, Figures 5 to 7 As shown, the attachment mechanism 20 also includes a first moving component 21, a second moving component 22, a third moving component 23, a first connecting seat 24 and a second connecting seat 25. The fixed end of the first moving component 21 is connected to the driving mechanism 30; the first connecting seat 24 is connected to the movable end of the first moving component 21, and the first roller 210 is rotatably connected to the first connecting seat 24. The second moving component 22 is movably connected to the first moving component 21 and can move synchronously with the movable end of the first moving component 21. The fixed end of the third moving component 23 is connected to the movable end of the second moving component 22; the second connecting seat 25 is connected to the movable end of the third moving component 23, and the second roller 220 is rotatably connected to the second connecting seat 25.

[0068] The first moving part 21, the second moving part 22 and the third moving part 23 are moving parts capable of linear reciprocating motion. The structures of the three moving parts can be the same, and the moving parts include moving parts capable of linear reciprocating motion such as air cylinders, oil cylinders, electric push rods, synchronous belt transmission mechanisms, screw transmission mechanisms, etc. The structures of the three moving parts can also be different, for example, the three moving parts are composed of two or more moving parts selected from air cylinders, oil cylinders, electric push rods, synchronous belt transmission mechanisms, screw transmission mechanisms, etc.

[0069] The first moving component 21 can reciprocate along the third direction. The first moving component 21 can be a cylinder, which is placed in the vertical direction, that is, the third direction, and the cylinder can drive the piston rod to reciprocate along the third direction. The first moving component 21 can be an oil cylinder, which is placed in the vertical direction, and the oil cylinder can drive the piston rod to reciprocate along the third direction. The first moving component 21 can be a screw transmission mechanism, which is placed in the vertical direction, and the motor can drive the nut on the screw to reciprocate along the third direction. The fixed end of the first moving component 21 can be connected to the driving mechanism 30 by screwing, and the first connecting seat 24 can be connected to the movable end of the first moving component 21 by screwing. The first moving component 21 is used to drive the first connecting seat 24 to reciprocate along the third direction. The first moving component 21 moves downward along the third direction so that the first roller 210 can contact the first surface 71; the first moving component 21 moves upward along the third direction to form a suitable distance between the first surface 71 of the target box 70 and the first roller 210, so that the rolled target box 70 can continue to be conveyed forward, and the next target box 70 to be rolled can be conveyed to the target position.

[0070] In some embodiments, the first connection seat 24 includes a frame 241 and a first connection plate 242. The frame 241 may be a square frame structure. Two first connection plates 242 are connected to the bottom of the frame 241. The two first connection plates 242 are arranged at intervals. The interval between the two first connection plates 242 is adapted to the length of the first roller 210. The first roller 210 is rotatably connected to the two first connection plates 242. For example, a bearing is installed on the first connection plate 242, and the mandrel of the first roller 210 is rotatably connected to the bearing, so that the first roller 210 and the first connection plate 242 are rotatably connected.

[0071] The second moving component 22 can reciprocate along the third direction. The second moving component 22 can be a cylinder, which is placed in the vertical direction, and the cylinder can drive the piston rod to reciprocate along the third direction. The second moving component 22 can be an oil cylinder, which is placed in the vertical direction, and the oil cylinder can drive the piston rod to reciprocate along the third direction. The second moving component 22 can be a screw transmission mechanism, which is placed in the vertical direction, and the motor can drive the nut on the screw to reciprocate along the third direction. The second moving component 22 is used to drive the third moving component 23 to move along the third direction. The second moving component 22 can move synchronously with the movable end of the first moving component 21. The second moving component 22 moves downward along the third direction to adjust the vertical spacing between the bottom surface of the second roller 220 and the first surface 71, that is, the height range of the second roller 220 contacting the second surface 72; the second moving component 22 moves upward along the third direction, and the second roller 220 can move to a suitable position above the target box 70, so that the next target box 70 to be rolled can be transported to the target position.

[0072] In some embodiments, the second moving component 22 is connected to the first moving component 21 through a first transition plate 26. The first transition plate 26 includes a first connecting block and a second connecting block that are perpendicular to each other, and the first connecting block can be connected to the movable end of the first moving component 21 by screw connection, and the second connecting block can be connected to the fixed end of the second moving component 22 by screw connection. As a result, the movable end of the first moving component 21 moves along the third direction, so that the second moving component 22 moves synchronously with the movable end of the first moving component 21 along the third direction.

[0073] In some embodiments, the third moving component 23 is connected to the second moving component 22 through the second transition plate 27. For example, the third moving component 23 is located below the second moving component 22, and the movable end of the second moving component 22 and the fixed end of the third moving component 23 are arranged perpendicular to each other. The top of the second transition plate 27 can be connected to the movable end of the second moving component 22 by screwing, and the bottom of the second transition plate 27 can be connected to the fixed end of the third moving component 23 by screwing.

[0074] The third moving part 23 can make linear reciprocating motion along the second direction. The second connecting seat 25 can be connected to the movable end of the third moving part 23 by screw connection. The third moving part 23 can be a cylinder, which is placed along the conveying direction, that is, the second direction, and the cylinder can drive the piston rod to reciprocate along the second direction. The third moving part 23 can be an oil cylinder, which is placed along the conveying direction, and the oil cylinder can drive the piston rod to reciprocate along the second direction. The third moving part 23 can be a screw transmission mechanism, which is placed along the conveying direction, and the motor can drive the nut on the screw to reciprocate along the second direction. The third moving part 23 is used to drive the second connecting seat 25 to reciprocate along the second direction, and the third moving part 23 moves along the second direction toward the direction close to the target box 70, so that the second roller 220 can contact the second surface 72; the third moving part 23 moves along the second direction toward the direction away from the target box 70, and forms a suitable distance between the second surface 72 of the target box 70 and the second roller 220, so that the rolled target box 70 can continue to be conveyed forward.

[0075] In some embodiments, the second connection seat 25 includes a second connection plate 251 and a third connection plate 252. The second connection plate 251 can be connected to the movable end of the third moving component 23 by screw connection. Two third connection plates 252 are arranged at one side of the second connection plate 251 at intervals. The interval between the two third connection plates 252 is adapted to the length of the second roller 220. The second roller 220 is rotatably connected to the two third connection plates 252. For example, a bearing is installed on the third connection plate 252, and the mandrel of the second roller 220 is rotatably connected to the bearing, so that the second roller 220 is rotatably connected to the third connection plate 252.

[0076] The three moving parts can move synchronously or asynchronously. Take the movement in the direction close to the first surface 71 and the second surface 72 as an example for explanation. The first moving part 21 and the second moving part 22 can move synchronously along the third direction until the first roller 210 contacts the first surface 71, and then the second moving part 22 moves a distance along the third direction; or the first moving part 21 can move along the third direction until the first roller 210 contacts the first surface 71, and then the second moving part 22 starts to move downward along the third direction. The third moving part 23 can move synchronously with the first moving part 21 and the second moving part 22, or the third moving part 23 can start to move along the second direction after the first moving part 21 and the second moving part 22 move into place. By reasonably setting the movement sequence of the three moving parts, the time taken for the first roller 210 and the second roller 220 to contact the first surface 71 and the second surface 72 is minimized.

[0077] The movement process of the three moving parts is described in detail below. The three moving parts are described by taking the cylinder as an example. The first moving part 21 includes a first cylinder, which includes a first cylinder body 211 and a first piston rod 212; the second moving part 22 includes a second cylinder, which includes a second cylinder body 221 and a second piston rod 222; the third moving part 23 includes a third cylinder, which includes a third cylinder body 231 and a third piston rod 232.

[0078] The first cylinder drives the first piston rod 212 to move downward along the third direction, and the first piston rod 212 drives the first connecting seat 24 and the second cylinder to move downward along the third direction until the first roller 210 contacts the first surface 71 or contacts both the first surface 71 and the sealing sticker 80, and the displacement of the first piston rod 212 is defined as the first displacement. After the first piston rod 212 extends by the first displacement, the first roller 210 contacts the first surface 71 or contacts both the first surface 71 and the sealing sticker 80, and the first piston rod 212 stops moving. Then the second cylinder drives the second piston rod 222 to move downward along the third direction, and the second piston rod 222 drives the third cylinder and the second connecting seat 25 to move downward along the third direction, and the displacement of the second piston rod 222 is defined as the second displacement. After the second piston rod 222 extends by the second displacement, the vertical distance between the bottom surface of the second roller 220 and the first surface 71 is the set target distance. That is, the second cylinder is used to drive the second roller 220 to move to a preset position away from the first surface 71. At the preset position, the vertical distance between the bottom surface of the second roller 220 and the first surface 71 is the target distance. The target distance is set according to actual needs. For example, the target distance is 30 mm, that is, the height dimension of the second roller 220 in contact with the second surface 72 is 30 mm, so as to avoid excessive contact area between the second roller 220 and the second surface 72, thereby crushing the target box 70.

[0079] When the size of the target box 70 changes, for example, the height of the target box 70 increases, after the first roller 210 contacts the first surface 71, the second cylinder drives the third cylinder and the second connecting seat 25 to continue to move downward along the third direction for a certain distance and then stop, so that the vertical distance between the bottom surface of the second roller 220 and the first surface 71 is the target distance, thereby being able to adapt to target boxes 70 of different heights, ensuring that the vertical distance between the bottom surface of the second roller 220 and the first surface 71 is always maintained at the target distance.

[0080] After the second cylinder drives the second piston rod 222 to move downwardly along the third direction into position, the third cylinder drives the third piston rod 232 to move along the second direction toward the second surface 72 until the second roller 220 contacts the second surface 72. The displacement of the third piston rod 232 is defined as the third displacement. After the third piston rod 232 is extended by the third displacement, the second roller 220 contacts the second surface 72, and the third piston rod 232 stops moving.

[0081] After the first roller 210 contacts the first surface 71 and the second roller 220 contacts the second surface 72 , the driving mechanism 30 drives the first roller 210 and the second roller 220 to move along the first direction, so that the sealing label 80 is firmly attached to the first surface 71 and the second surface 72 .

[0082] After rolling is completed, the third cylinder drives the third piston rod 232 to move in the second direction away from the second surface 72, and the displacement of the third piston rod 232 retracts is the third displacement; then the second cylinder drives the second piston rod 222 to move in the third direction away from the first surface 71, and the displacement of the second piston rod 222 retracts is the second displacement; then the first cylinder drives the first piston rod 212 to move in the third direction away from the first surface 71, and the displacement of the first piston rod 212 retracts is the first displacement. The first roller 210 and the second roller 220 return to the initial position, and the conveying mechanism 10 restarts to convey the rolled target box 70 to the tail end of the conveyor belt, and at the same time conveys the next target box 70 to be rolled to the target position.

[0083] In this embodiment, the first moving component 21 is used to drive the first connecting seat 24 and the second moving component 22 to move along the third direction, so that the first roller 210 can contact or separate from the first surface 71; the second moving component 22 is used to drive the third moving component 23 and the second connecting seat 25 to move along the third direction, so that the vertical distance between the bottom surface of the second roller 220 and the first surface 71 is the target distance, which can adapt to target boxes 70 of different heights; the third moving component 23 is used to drive the second connecting seat 25 to move along the second direction, so that the second roller 220 can contact or separate from the second surface 72. Through the coordinated cooperation of the three moving components, the first roller 210 can contact or separate from the first surface 71, and the second roller 220 can contact or separate from the second surface 72, which can adapt to target boxes 70 of different heights, and at the same time, it can avoid the second roller 220 from contacting the second surface 72 too much and crushing the target box 70, which is beneficial to improving the versatility of the sealing device and the reliability of the use of the sealing device.

[0084] In the embodiment of the present disclosure, the first moving component 21 includes a first driving member and a first regulating valve, and the first regulating valve is used to adjust the driving force of the first driving member so that the first roller 210 contacts the first surface 71 at a first preset pressure. The third moving component 23 includes a second driving member and a second regulating valve, and the second regulating valve is used to adjust the driving force of the second driving member so that the second roller 220 contacts the second surface 72 at a second preset pressure.

[0085] The first moving part 21 can make the first roller 210 contact the first surface 71 at a first preset pressure, and the third moving part 23 can make the second roller 220 contact the second surface 72 at a second preset pressure. The contact pressure between the first roller 210 and the first surface 71 is the first preset pressure, and the contact pressure between the second roller 220 and the second surface 72 is the second preset pressure. The pressure values ​​of the first preset pressure and the second preset pressure are not specifically limited, ensuring that the sealing sticker 80 can be closely attached to the first surface 71 and the second surface 72 without crushing the target box 70.

[0086] In some embodiments, the first moving component 21 includes a first driving member and a first regulating valve, and the first driving member includes a cylinder, an oil cylinder, etc. For example, the first driving member includes a cylinder, and this cylinder is defined as a first cylinder. The first moving component 21 also includes a first gas circuit, and the first regulating valve is arranged on the first gas circuit. One end of the first gas circuit is connected to the gas source, and the other end is connected to the air inlet of the first cylinder. By adjusting the opening angle of the first regulating valve, the amount of gas entering the first cylinder is increased or decreased, thereby adjusting the output pressure of the first cylinder. By adjusting the opening angle of the first regulating valve, the output pressure of the first cylinder is made to be the first preset pressure, and then the pressure between the first roller 210 and the first surface 71 is made to be the first preset pressure.

[0087] The second moving part 22 includes a cylinder, which is defined as a second cylinder. The second moving part 22 also includes a second gas path, one end of which is connected to the gas source, and the other end is connected to the air inlet of the second cylinder. A regulating valve may be provided on the second gas path, or may not be provided, depending on actual needs.

[0088] The third moving part 23 includes a second driving part and a second regulating valve, and the second driving part includes a cylinder, an oil cylinder, etc. For example, the second driving part includes a cylinder, and this cylinder is defined as a third cylinder. The third moving part 23 also includes a third gas circuit, and the second regulating valve is arranged on the third gas circuit. One end of the third gas circuit is connected to the gas source, and the other end is connected to the air inlet of the third cylinder. By adjusting the opening angle of the second regulating valve, the amount of gas entering the third cylinder is increased or decreased, thereby adjusting the output pressure of the third cylinder. By adjusting the opening angle of the second regulating valve, the output pressure of the third cylinder is made to be the second preset pressure, and then the pressure between the second roller 220 and the second surface 72 is made to be the second preset pressure. The first preset pressure and the second preset pressure can be the same or different. The first roller 210 contacts the first surface 71, and the target box 70 is carried by the conveyor belt. The contact between the first roller 210 and the first surface 71 is relatively stable, and the first preset pressure can be less than the second preset pressure. The second preset pressure can be 10N, 15N, 20N, etc. The range of the second preset pressure is set according to actual needs, for example, greater than or equal to 10N and less than or equal to 20N. When the first preset pressure and the second preset pressure are the same, the first preset pressure and the second preset pressure can both be 10N, and the pressure value is not specifically limited. When the first preset pressure and the second preset pressure are different, the first preset pressure can be 10N, and the second preset pressure can be 15N, and the pressure value is not specifically limited.

[0089] During the process of the first roller 210 rolling the first surface 71 and the second roller 220 rolling the second surface 72, if the pressure is too small, the sealing sticker 80 may not be firmly attached to the first surface 71 and the second surface 72; if the pressure is too large, the target box 70 may be crushed or deformed.

[0090] In this embodiment, the output pressure of the first driving member is adjusted by the first regulating valve so that the contact pressure between the first roller 210 and the first surface 71 is the first preset pressure; the output pressure of the second driving member is adjusted by the second regulating valve so that the contact pressure between the second roller 220 and the second surface 72 is the second preset pressure. Thus, the first roller 210 rolls the first surface 71 and the second roller 220 rolls the second surface 72, which can ensure that the sealing sticker 80 is closely attached to the first surface 71 and the second surface 72, ensuring the sealing quality, and can effectively prevent the target box 70 from being crushed.

[0091] In the embodiments of the present disclosure, Figures 1 to 3As shown, the conveying mechanism 10 includes a first conveying component 11 and a second conveying component 12. The second conveying component 12 is disposed on one side of the first conveying component 11, and the bearing surface of the first conveying component 11 and the bearing surface of the second conveying component 12 are located in the same plane. The first conveying component 11 and the second conveying component 12 cooperate to transport the target box 70 to the target position; when the target box 70 is at the target position, the first surface 71 is disposed corresponding to the first roller 210, and the second surface 72 is disposed corresponding to the second roller 220.

[0092] The first conveying member 11 and the second conveying member 12 are sequentially arranged along the conveying direction, and the first conveying member 11 and the second conveying member 12 may both be belt conveyors.

[0093] In some embodiments, the first conveying component 11 includes a first motor and a first conveyor belt, and the first motor is used to drive the first conveyor belt to rotate; the second conveying component 12 includes a second motor and a second conveyor belt, and the second motor is used to drive the second conveyor belt to rotate. The bearing surface of the first conveyor belt and the bearing surface of the second conveyor belt are located in the same plane. There is a suitable gap between the tail end of the first conveyor belt and the head end of the second conveyor belt.

[0094] The target box 70 to be rolled is placed on the first conveyor belt, and as the first conveyor belt and the second conveyor belt rotate, the target box 70 to be rolled is conveyed to the target position on the second conveyor belt. At the target position, the first surface 71 corresponds to the first roller 210, and the second surface 72 corresponds to the second roller 220.

[0095] When the target box 70 reaches the target position, the second conveyor belt stops rotating, and the three moving parts start to move. First, the first moving part 21 moves downward along the third direction by a first displacement amount, and at the same time adjusts the opening angle of the first regulating valve so that the first roller 210 contacts the first surface 71 with a first preset pressure. Then, the second moving part 22 continues to move downward along the third direction by a second displacement amount, so that the vertical distance between the bottom surface of the second roller 220 and the first surface 71 is the target distance. Afterwards, the third moving part 23 moves along the second direction toward the direction close to the second surface 72 by a third displacement amount, and at the same time adjusts the opening angle of the second regulating valve so that the second roller 220 contacts the second surface 72 with a second preset pressure. Next, the driving mechanism 30 drives the first roller 210 and the second roller 220 to roll the first surface 71 and the second surface 72.

[0096] It is understandable that when the second conveyor belt stops rotating and the target box 70 at the target position is rolled, the first conveyor belt can still be in a rotating state until the first conveyor belt transports the next target box 70 to be rolled to a position close to the second conveyor belt, and the target box 70 at the target position on the second conveyor belt is still in a rolled state, at which time the first motor is turned off and the first conveyor belt stops rotating. In other words, the time when the first conveyor belt and the second conveyor belt stop rotating can be asynchronous. While rolling the target box 70 on the second conveyor belt, the first conveyor belt can continue to transport the target box 70 to be rolled, which is conducive to speeding up the production rhythm and improving work efficiency.

[0097] After the rolling operation is completed, the first roller 210 and the second roller 220 return to their initial positions, the first motor and the second motor restart, the first conveyor belt and the second conveyor belt continue to rotate, and the rolled target box 70 is conveyed to the tail end of the second conveyor belt, and the next target box 70 to be rolled is conveyed to the target position.

[0098] In this embodiment, the target box 70 to be rolled is conveyed to the target position through the coordinated cooperation of the first conveying component 11 and the second conveying component 12, and the rolled target box 70 is conveyed to the tail end of the second conveying component 12. During the rolling process of the target box 70 at the target position, the first conveying component 11 can continue to convey the target box 70, which is conducive to speeding up the production cycle and improving work efficiency.

[0099] In the embodiments of the present disclosure, Figure 8 As shown, the conveying mechanism 10 is provided with a sensing component, which includes a first sensing unit 13 and a second sensing unit 14 arranged along the conveying direction. The first sensing unit 13 is used to detect the target box 70 so that only one target box 70 can be conveyed to the target position, and the second sensing unit 14 can cause the second conveying component 12 to suspend conveying when the target box 70 is transported to the target position.

[0100] In some embodiments, the first conveying component 11 further includes a first support frame, a first active roller, and a first driven roller. The first active roller and the first driven roller are rotatably mounted on the first support frame, and the first conveyor belt is sleeved on the first active roller and the first driven roller. The sensing component includes a first sensing unit 13 and a second sensing unit 14. The first sensing unit 13 is mounted at the end of the first support frame. The position of the first sensing unit 13 is defined as the first position. The first sensing unit 13 includes a transmitter and a receiver. The transmitter and the receiver are mounted on opposite sides of the first support frame to sense whether there is a target box 70 to be rolled at the first position. The second sensing unit 14 is mounted on the second support frame, close to the head end of the second support frame. The position of the second sensing unit 14 is defined as the second position, and the second position corresponds to the target position. The second sensing unit 14 includes a transmitter and a receiver. The transmitter and the receiver are mounted on opposite sides of the second support frame to sense whether there is a target box 70 to be rolled at the target position.

[0101] The sealing device also includes a controller, and the conveying mechanism 10, the attaching mechanism 20 and the driving mechanism 30 are all connected to the controller. The second sensing unit 14 detects that the target box 70 to be rolled moves to the target position, and sends a second sensing signal to the controller. The controller controls the second motor to turn off, and the second conveyor belt stops rotating. Then, the controller sends a motion signal to the attaching mechanism 20, and the attaching mechanism 20 drives the first roller 210 to contact the first surface 71, and the second roller 220 to contact the second surface 72. After that, the controller sends a rolling signal to the driving mechanism 30, and the driving mechanism 30 drives the first roller 210 and the second roller 220 to roll the target box 70.

[0102] The first sensing unit 13 detects that there is a target box 70 to be rolled at the first position, and the second sensing unit 14 detects that there is a target box 70 to be rolled at the second position, and the first sensing unit 13 sends a first sensing signal to the controller, and the second sensing unit 14 sends a second sensing signal to the controller. The controller controls the first motor to turn off according to the first sensing signal and the second sensing signal, and the first conveyor belt stops rotating, so as to prevent the target box 70 to be rolled on the first conveyor belt from continuing to move and colliding with the target box 70 in a rolling state on the second conveyor belt.

[0103] After completing the rolling of the target box 70 at the target position, the first roller 210 and the second roller 220 return to the initial position, and the controller receives a rolling completion signal, and the controller controls the first motor and the second motor to restart to transport the next target box 70 to be rolled to the target position.

[0104] Optionally, the sensing component further includes a third sensing unit 15 and a fourth sensing unit 16, and the third sensing unit 15 and the fourth sensing unit 16 are located on opposite sides of the second sensing unit 14, and the third sensing unit 15 and the fourth sensing unit 16 are both arranged close to the second sensing unit 14. The position where the third sensing unit 15 is located is defined as the third position. The second sensing unit 14 senses that there is a target box 70 at the second position, and the third sensing unit 15 senses that there is no target box 70 at the third position, and the controller sends a motion signal to the attachment mechanism 20, and the three moving components drive the first roller 210 and the second roller 220 to move, which can prevent the two rollers from crushing the target box 70 at the third position during movement when the two target boxes 70 to be rolled are conveyed to the second conveyor belt at the same time.

[0105] When the number of the first roller 210 and the number of the second roller 220 are both two, the two first rollers 210 are spaced apart along the second direction, and the two second rollers 220 are spaced apart along the second direction. One group of rollers rolls the sealing stickers 80 at the first surface 71 and the second surface 72, and the other group of rollers rolls the sealing stickers 80 at the first surface 71 and the third surface 73. The position where the fourth sensing unit 16 is located is defined as the fourth position. The second sensing unit 14 senses that there is a target box 70 at the second position, and the fourth sensing unit 16 senses that there is no target box 70 at the fourth position. The controller sends a motion signal to the attachment mechanism 20, and the three moving parts drive the first roller 210 and the second roller 220 to move, which can prevent the target box 70 located behind the target position from being removed after rolling, and the two rollers from crushing the target box 70 located at the fourth position during movement.

[0106] The third sensing unit 15 and the fourth sensing unit 16 are used to sense whether there are target boxes 70 on both sides of the target position, so as to prevent the first roller 210 and the second roller 220 from crushing the target box 70 located in front of or behind the target position when the first roller 210 and the second roller 220 move toward the target box 70 near the target position.

[0107] Optionally, the sensing component also includes a fifth sensing unit 17, and the fifth sensing unit 17 is installed at the tail end of the second support frame, and the position where the fifth sensing unit 17 is located is defined as the fifth position. The fifth sensing unit 17 is used to sense whether there is a rolled target box 70 at the fifth position. The rolled target box 70 moves toward the tail end of the second conveyor belt as the second conveyor belt rotates, and moves to a position close to the tail end to be transferred to other equipment. If the fifth sensing unit 17 senses that there is a target box 70 at the fifth position, it indicates that the rolled target box 70 has not been transferred away in time, and material stacking occurs at the tail end of the second conveyor belt. The sealing device also includes an alarm, and the controller receives the fifth sensing signal of the fifth sensing unit 17, controls the alarm to send an alarm signal, and prompts the staff or the transfer equipment to transfer the target box 70 at the tail end of the second conveyor belt in time.

[0108] In this embodiment, the controller controls the working state of the first conveying component 11 according to the first sensing signal and the second sensing signal to ensure that when the target box 70 at the target position is rolled, the target box 70 to be rolled does not collide with the target box 70 at the target position. The controller controls the working state of the first conveying component 11 and the second conveying component 12 according to the second sensing signal to convey the target box 70 to be rolled to the target position, and ensures the safety and reliability of the use of the sealing device through the first sensing unit 13 and the second sensing unit 14.

[0109] In the embodiments of the present disclosure, Figures 1 to 4 As shown, the sealing device further includes a clamping mechanism 40 and / or a limiting mechanism 50, and the clamping mechanism 40 is in communication connection with the conveying mechanism 10 and the attaching mechanism 20. The clamping mechanism 40 includes a first clamping component and a second clamping component, and the first clamping component and the second clamping component are arranged on opposite sides of the conveying mechanism 10, and the first clamping component and the second clamping component can move toward or away from each other to clamp or release the target box 70 at the target position. The limiting mechanism 50 includes a first limiting component and a second limiting component, and the first limiting component and the second limiting component are arranged on opposite sides of the conveying mechanism 10, and a limiting area is formed between the first limiting component and the second limiting component.

[0110] The clamping mechanism 40 includes a first clamping member and a second clamping member, which are mounted on opposite sides of the second support frame, and the first clamping member and the second clamping member are opposite to the target box 70 at the target position. Both clamping members can be motion mechanisms such as air cylinders and oil cylinders that can perform telescopic motion.

[0111] In some embodiments, the first clamping component includes a piston rod and a first pressure plate connected to the piston rod, and the first pressure plate can move toward or away from the fourth surface; the second clamping component includes a piston rod and a second pressure plate connected to the piston rod, and the second pressure plate can move toward or away from the fifth surface.

[0112] After the first roller 210 contacts the first surface 71 and the second roller 220 contacts the second surface 72, the controller sends a clamping signal to the clamping mechanism 40, the first clamping component and the second clamping component move toward each other, the first clamping component drives the first pressing plate to move toward the direction close to the fourth surface, and the second clamping component drives the second pressing plate to move toward the direction close to the fifth surface, until the first pressing plate contacts the fourth surface and the second pressing plate contacts the fifth surface, so as to clamp the target box 70. Afterwards, the controller sends a rolling signal to the driving mechanism 30, and the driving mechanism 30 drives the first roller 210 and the second roller 220 to move in the rolling direction. During the movement of the first roller 210 and the second roller 220 in the first direction, since the first pressing plate and the second pressing plate clamp the target box 70 in the first direction, the deviation of the target box 70 can be effectively avoided, thereby ensuring that the sealing sticker 80 can be completely in contact with the first roller 210 and the second roller 220 during the rolling process, thereby ensuring the sealing quality.

[0113] After rolling is completed, the first clamping member and the second clamping member move in opposite directions, the first clamping member drives the first pressing plate to move in a direction away from the fourth surface, and the second clamping member drives the second pressing plate to move in a direction away from the fifth surface. Afterwards, the rolled target box 70 is conveyed to the tail end of the second conveyor belt.

[0114] The limiting mechanism 50 includes a first limiting component and a second limiting component, and the first limiting component and the second limiting component are installed on opposite sides of the first support frame. Figure 2 As shown, the first limiting component includes a first limiting rod 51, the length direction of the first limiting rod 51 is consistent with the conveying direction, and the length of the first limiting rod 51 is adapted to the length of the first conveyor belt. The second limiting component includes a second limiting rod, the length direction of the second limiting rod is consistent with the conveying direction, and the length of the second limiting rod is adapted to the length of the first conveyor belt.

[0115] The distance between the first limiting rod 51 and the second limiting rod is slightly larger than the distance between the fourth surface and the fifth surface of the target box 70. A limiting area is formed between the first limiting rod 51 and the second limiting rod. The target box 70 to be rolled moves from the first conveyor belt toward the second conveyor belt in the limiting area, and the limiting area can prevent the target box 70 from deviating during the movement of the first conveyor belt. In addition, the target box 70 to be rolled is placed at the head end of the first conveyor belt. If the target box 70 is not placed correctly, when the target box 70 moves with the first conveyor belt, the first limiting rod 51 and the second limiting rod play a role of correcting the deviation, so that the target box 70 can move from the first conveyor belt to the second conveyor belt in a target posture.

[0116] In this embodiment, before rolling, the target box 70 to be rolled is clamped by the clamping mechanism 40, which can effectively prevent the target box 70 from shifting during the rolling process and ensure the sealing quality; the target box 70 to be rolled moves from the first conveyor belt to the second conveyor belt in the limiting area, ensuring that the target box 70 can move to the target position of the second conveying component 12 in a target posture, thereby ensuring that it can fully contact with the sealing sticker 80 during the rolling process and ensure the sealing quality.

[0117] In the embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the driving mechanism 30 includes a first driving assembly 31 and a second driving assembly 32. The second driving assembly 32 is movably connected to the first driving assembly 31, and the attaching mechanism 20 is connected to the second driving assembly 32. The first driving assembly 31 is used to drive the first roller 210 and the second roller 220 to move synchronously along the first direction. The second driving assembly 32 is used to drive the attaching mechanism 20 to move along the second direction to adjust the contact area between the first roller 210 and the first surface 71, and the second direction intersects with the first direction.

[0118] The driving mechanism 30 is located above the attaching mechanism 20 and includes a first driving component 31 and a second driving component 32. The first driving component 31 can move along a first direction and the second driving component 32 can move along a second direction. The first direction may be perpendicular to the second direction.

[0119] In some embodiments, the first drive assembly 31 and the second drive assembly 32 can both be linear modules. The first drive assembly 31 includes a motor, a first slide rail and a first slider in sliding connection; the second drive assembly 32 includes a motor, a second slide rail and a second slider in sliding connection. The first slider can slide in a first direction, and the second slider can slide in a second direction. The fixed end of the second slide rail is connected to the first slider, and the fixed end of the attachment mechanism 20 is connected to the second slider, for example, the cylinder body of the first cylinder is connected to the second slider.

[0120] The second driving assembly 32 drives the second slider to slide along the second slide rail, driving the first roller 210 and the second roller 220 to move along the second direction. The target box 70 to be rolled moves to the target position. If the width of the target box 70 changes, the second driving assembly 32 drives the second slider to slide along the second slide rail, so that the first roller 210 moves along the second direction to a position relative to the first part of the sealing sticker 80, and adjusts the contact area between the first roller 210 and the first surface 71 to ensure that the first part of the sealing sticker 80 can be fully contacted during the rolling process.

[0121] After the contact area between the first roller 210 and the first surface 71 is adjusted by the second driving component 32, the first driving component 31 drives the first slider to slide along the first slide rail, driving the second driving component 32 to move along the first direction, and the first roller 210 and the second roller 220 move synchronously with the first slider to achieve rolling of the sealing label 80.

[0122] In this embodiment, the second driving assembly 32 drives the attaching mechanism 20 to move along the second direction, so that the first roller 210 can be in full contact with the sealing sticker 80 at the first surface 71, and can adapt to target boxes 70 of different sizes, which is conducive to improving the versatility of the sealing device. For example, it can adapt to color boxes with a length dimension of 160-200mm, a width dimension of 80-100mm, and a height dimension of 28-65mm. Through the same sealing device, color boxes of multiple specifications and sizes can be rolled and sealed, which effectively improves the versatility of the sealing device. For example, the size of the color box can be 160*80*28mm, and the size of the color box can be 200*100*65mm. The sealing device can roll and seal color boxes of multiple specifications and sizes between 160*80*28mm and 200*100*65mm.

[0123] In the embodiments of the present disclosure, Figure 3 and Figure 4 As shown, the attaching mechanism 20 further includes a third roller 230, which is used to contact the third surface 73 of the target box 70 so that the sealing sticker 80 is attached to the third surface 73, and the third surface 73 intersects with the first surface 71. The driving mechanism 30 is also used to drive the first roller 210, the second roller 220 and the third roller 230 to move synchronously along the first direction.

[0124] In some embodiments, the third roller 230 is disposed opposite to the second roller 220 , and the sealing sticker 80 can be a long strip of sealing sticker 80 , which is attached to the first surface 71 , the second surface 72 and the third surface 73 , that is, the sealing sticker 80 after attachment is U-shaped.

[0125] The positions of the first roller 210, the second roller 220 and the third roller 230 are adjusted by the attaching mechanism 20, so that the first roller 210 contacts the middle area of ​​the first surface 71, the second roller 220 contacts the second surface 72, and the third roller 230 contacts the third surface 73. The first driving assembly 31 drives the first slider to slide along the first slide rail, driving the first roller 210, the second roller 220 and the third roller 230 to move synchronously along the first direction, so that the sealing sticker 80 is closely attached to the first surface 71, the second surface 72 and the third surface 73 of the target box 70.

[0126] In some embodiments, the integral component consisting of the first moving component 21, the second moving component 22 and the third moving component 23 is defined as a first moving assembly.

[0128] When the color box is sealed by two sealing stickers 80, one sealing sticker 80 is first attached to the first surface 71 and the second surface 72 of the target box 70, and the other sealing sticker 80 is attached to the first surface 71 and the third surface 73 of the target box 70. The target box 70 attached with two sealing stickers 80 moves to the target position.

[0129] The second driving assembly 32 drives the second slider to slide along the second slide rail, driving the first roller 210 and the second roller 220 to move along the second direction. At the same time, the fourth driving assembly 34 drives the fourth slider to slide along the fourth slide rail, driving the third roller 230 and the fourth roller 240 to move along the second direction, thereby adjusting the contact area between the first roller 210 and the first surface 71 and the contact area between the fourth roller 240 and the first surface 71, so that the first roller 210 is located directly above one sealing sticker 80, and the fourth roller 240 is located directly above another sealing sticker 80. Afterwards, the first moving assembly and the second moving assembly move downward along the third direction, so that the first roller 210 can fully contact one sealing sticker 80 on the first surface 71, and the fourth roller 240 can fully contact another sealing sticker 80 on the first surface 71. The target boxes 70 of different widths can be adapted, and two sealing stickers 80 can be rolled at the same time, which is conducive to improving the sealing efficiency.

[0130] In this embodiment, the attaching mechanism 20 also includes a third roller 230, and the driving mechanism 30 drives the first roller 210, the second roller 220 and the third roller 230 to move synchronously along the first direction, so that the U-shaped sealing sticker 80 can be attached to the target box 70; the attaching mechanism 20 also includes a fourth roller 240, and the driving mechanism 30 adjusts the distance between the first roller 210 and the fourth roller 240 to adapt to sealing stickers 80 of different widths, thereby improving the versatility of the sealing device, and at the same time rolling the two sealing stickers 80 on the target box 70 is beneficial to improving the sealing efficiency.

[0131] In the embodiments of the present disclosure, Figure 1 and Figure 3 As shown, the sealing device further includes a collecting device 60, which is disposed above the conveying mechanism 10 and is disposed corresponding to the target position. The collecting device 60 can collect the position of the sealing sticker 80 attached to the target box 70 to determine the rolling area of ​​the first roller 210 and the second roller 220 on the target box 70.

[0132] In some embodiments, the attaching mechanism 20 includes a first roller 210 and a second roller 220, and the collecting device 60 includes a collecting component, which includes a camera for collecting position information of the sealing sticker 80 on the target box 70 to determine a first rolling area of ​​the first roller 210 on the target box 70 and a second rolling area of ​​the second roller 220 on the target box 70. The first driving component 31 and the second driving component 32 drive the first roller 210 and the second roller 220 to move to a position close to the rolling area according to the position information collected by the collecting device 60, and then the first roller 210 and the second roller 220 can be accurately and completely contacted with the sealing sticker 80 through the movement of the first moving component. According to the position information collected by the collecting device 60, the positions of the first roller 210 and the second roller 220 are preliminarily adjusted by the second driving component 32, and then rolled along the first direction, which is conducive to shortening the rolling stroke of the first driving component 31, which is conducive to improving the sealing efficiency and ensuring the accuracy of the rolling position.

[0133] In some embodiments, the attaching mechanism 20 includes a first roller 210, a second roller 220, a third roller 230 and a fourth roller 240, and the collection device 60 includes a first collection component 61 and a second collection component 62, the first collection component 61 and the second collection component 62 are connected to the controller in communication, and four driving components are connected to the controller in communication. One sealing sticker 80 is attached to the first surface 71 and the second surface 72 of the target box 70, and another sealing sticker 80 is attached to the first surface 71 and the third surface 73 of the target box 70. The first collection component 61 is used to collect the first position information of one sealing sticker 80, and the second collection component 62 is used to collect the second position information of another sealing sticker 80.

[0134] The first driving assembly 31 and the second driving assembly 32 drive the first roller 210 and the second roller 220 to move to a first target rolling area corresponding to one sealing sticker 80 according to the first position information collected by the first collecting assembly 61. In the first target rolling area, the first roller 210 is located directly above one sealing sticker 80. The third driving assembly 33 and the fourth driving assembly 34 drive the third roller 230 and the fourth roller 240 to move to a second target rolling area corresponding to another sealing sticker 80 according to the second position information collected by the second collecting assembly 62. In the second target rolling area, the fourth roller 240 is located directly above another sealing sticker 80.

[0135] Then, the first roller 210 and the second roller 220 can be precisely and completely contacted with one sealing sticker 80 through the movement of the first moving component, and the third roller 230 and the fourth roller 240 can be precisely and completely contacted with another sealing sticker 80 through the movement of the second moving component. According to the first position information collected by the first acquisition component 61 and the second position information collected by the second acquisition component 62, the positions of the first roller 210, the second roller 220, the third roller 230 and the fourth roller 240 are preliminarily adjusted, and then rolled along the first direction, which is conducive to shortening the rolling stroke of the first driving component 31 and the third driving component 33, which is conducive to improving the sealing efficiency and ensuring the accuracy of the rolling position.

[0136] Optionally, the acquisition device 60 also includes a third acquisition component, which includes a camera for collecting image information of the sealing sticker 80 on the target box 70 after rolling, and detecting the state of the sealing, that is, whether the degree of fit between the sealing sticker 80 and the first surface 71 and the second surface 72 meets the requirements. If the sealing sticker 80 has problems such as warping, it can prompt the operator that the sealing quality of the target box 70 after the current rolling is unqualified, and the target box 70 needs to be reworked. The rework process includes rolling the target box 70 with unqualified sealing quality again, or removing the sealing sticker 80, re-attaching a new sealing sticker 80 and rolling again to ensure that the sealing quality meets the requirements.

[0137] In this embodiment, the position information of the sealing sticker 80 attached to the target box 70 is collected by the collection device 60, and the driving mechanism 30 drives the attaching mechanism 20 to move along the first direction and the second direction according to the position information, and preliminarily adjusts the positions of the first roller 210 and the second roller 220. Thereafter, the attaching mechanism 20 drives the first roller 210 and the second roller 220 to move to the first surface 71 and the second surface 72 to contact each other, and then rolls along the first direction, which is beneficial to shortening the rolling stroke of the driving mechanism 30 along the first direction, which is beneficial to improving the sealing efficiency and ensuring the accuracy of the rolling position.

[0138] like Fig. 9 As shown, the present disclosure also provides a sealing method of a sealing device, the sealing method comprising:

[0139] Step 110: transporting materials to a target location, the materials including a target box 70 and a sealing sticker 80 attached to the target box 70;

[0140] Step 120: Adjust the first roller 210 and the second roller 220 of the attaching mechanism 20 so that the first roller 210 contacts the first surface 71 of the target box 70 so that the sealing sticker 80 is attached to the first surface 71, and the second roller 220 contacts the second surface 72 of the target box 70 so that the sealing sticker 80 is attached to the second surface 72;

[0141] Step 130 : driving the first roller 210 and the second roller 220 to move so that the sealing label 80 and the target box 70 are attached to each other.

[0142] The structure of the sealing device is as described above and will not be described again here. The sealing device includes a conveying mechanism 10, an attaching mechanism 20 and a driving mechanism 30. The attaching mechanism 20 includes a first moving part 21, a second moving part 22, a third moving part 23, a first roller 210 and a second roller 220. The driving mechanism 30 includes a first driving assembly 31 and a second driving assembly 32.

[0143] First, the conveying mechanism 10 conveys the material to be rolled to a target position, wherein the material includes a target box 70 and a sealing sticker 80 attached to the target box 70 .

[0144] Then, the first moving component 21 of the attaching mechanism 20 moves downward along the third direction by a first displacement amount, so that the first roller 210 contacts the first surface 71; then, the second moving component 22 continues to move downward along the third direction by a second displacement amount, so that the distance between the bottom surface of the second roller 220 and the first surface 71 meets the target distance; then, the third moving component 23 moves along the second direction by a third displacement amount, so that the second roller 220 contacts the second surface 72.

[0145] Afterwards, the driving mechanism 30 drives the first roller 210 and the second roller 220 to move in the first direction. During the movement of the first roller 210 in the first direction, the first part of the sealing sticker 80 is tightly fitted with the first surface 71 due to the rotational movement and linear movement of the first roller 210; during the movement of the second roller 220 in the first direction, the second part of the sealing sticker 80 is tightly fitted with the second surface 72 due to the rotational movement and linear movement of the second roller 220, thereby achieving the fitting of the sealing sticker 80 with the target box 70, which is beneficial to improving the sealing quality and the sealing efficiency.

[0146] In some embodiments, the conveying mechanism 10 includes a first conveying component 11 and a second conveying component 12 which are arranged in sequence. The attaching mechanism 20 also includes a third roller 230 and a fourth roller 240, and one sealing sticker 80 is rolled by the first roller 210 and the second roller 220, and another sealing sticker 80 is rolled by the third roller 230 and the fourth roller 240. The driving mechanism 30 includes a first driving assembly 31, a second driving assembly 32, a third driving assembly 33 and a fourth driving assembly 34. The first clamping component and the second clamping component are arranged on opposite sides of the second conveying component 12.

[0147] The working process of the sealing device is described in detail below with a specific embodiment: The sealing device rolls two sealing stickers 80 simultaneously.

[0148] As the first and second conveyor belts rotate, the target box 70 to be rolled moves to the target position. The second sensing unit 14 detects the target box 70 to be rolled at the target position and sends a second sensing signal to the controller, which controls the second motor to turn off and the second conveyor belt stops rotating.

[0149] The first collecting component 61 collects the first position information of a sealing sticker 80 on the target box 70, and the second collecting component 62 collects the second position information of another sealing sticker 80 on the target box 70. The driving mechanism 30 drives the attaching mechanism 20 to move along the first direction and / or the second direction according to the first position information and the second position information, so that the first roller 210 and the second roller 220 move to the area just above one sealing sticker 80, and the third roller 230 and the fourth roller 240 move to the area just above another sealing sticker 80. Afterwards, the first moving component and the second moving component move along the third direction, so that the first roller 210 and the fourth roller 240 contact the first surface 71; the first moving component and the second moving component move along the second direction, so that the second roller 220 contacts the second surface 72, and the third roller 230 contacts the fourth surface. During the movement of the first moving component and the second moving component, the opening angles of the first regulating valve and the second regulating valve are adjusted so that the first roller 210 contacts the first surface 71 at a first preset pressure, the second roller 220 contacts the second surface 72 at a second preset pressure, the third roller 230 contacts the third surface 73 at a third preset pressure, and the fourth roller 240 contacts the first surface 71 at a fourth preset pressure.

[0150] Then, the first clamping member and the second clamping member move toward each other along the first direction, the first pressing plate contacts the fourth surface of the target box 70 , and the second pressing plate contacts the fifth surface of the target box 70 to clamp the target box 70 .

[0151] Afterwards, the first driving assembly 31 and the third driving assembly 33 move in the first direction, so that the first roller 210 and the second roller 220 roll one sealing sticker 80, and the third roller 230 and the fourth roller 240 roll the other sealing sticker 80. Synchronously rolling the two sealing stickers 80 is conducive to improving the sealing efficiency.

[0152] After the target box 70 is rolled, the four rollers return to the initial position, the controller controls the first motor and the second motor to restart, the rolled target box 70 is conveyed to the tail end of the second conveyor belt, and the next target box 70 to be rolled is conveyed to the target position. Referring to the above steps, the next target box 70 is rolled.

[0153] It is understandable that, when only one sealing label 80 is attached to the target box 70, the third roller 230 and the fourth roller 240 do not work; when two sealing labels 80 are attached to the target box 70, the four rollers work simultaneously.

[0154] The sealing device and sealing method provided by the present disclosure can adapt to target boxes 70 of different heights and widths, and have strong versatility; can roll two sealing stickers 80 synchronously, which is beneficial to improving the sealing efficiency; and can effectively improve the sealing quality.
