Description

Technical Field

[0001] This utility model relates to the field of packaging box folding technology, specifically a packaging box folding mechanism. Background Technology

[0002] Existing packaging box folding equipment often suffers from inaccurate positioning, which can easily lead to deviations in the folding position. Furthermore, it relies heavily on manual intervention to control the folding process, resulting in low operational efficiency. In addition, some equipment lacks sufficient support stability or has an unreasonable design of the pressure rollers, which may cause the packaging boxes to shift during transport or be damaged during folding, ultimately affecting the folding quality and overall production results.

[0003] To address this issue, we propose a packaging box folding mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging box folding mechanism, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging box folding mechanism, comprising: The mounting brackets are arranged horizontally, with two mounting brackets arranged in pairs and parallel to each other. The mounting bracket has a mounting plate fixedly mounted on its top surface, and the top surface of the mounting bracket located at the rear has a mounting opening. A conveying mechanism is installed between the two mounting brackets; A roll forming hem assembly is installed between the mounting plate and the conveying mechanism, and the roll forming hem assembly can move vertically relative to the belt in the conveying mechanism; A positioning component, installed between two mounting plates, is movable vertically along the belt and is used to position and clamp the packaging box that needs to be folded.

[0006] Preferably, two symmetrically arranged brackets are fixedly installed on the bottom surface of the mounting frame. The brackets are H-shaped. The two symmetrical H-shaped brackets on the bottom surface of the mounting frame can enhance the overall support stability of the mechanism and avoid the impact of shaking on the conveying accuracy and folding quality during operation.

[0007] Preferably, the roll-pressed hemming assembly includes: The pressure roller is positioned parallel to the belt at the mounting opening. The T-shaped column is rotatably configured with an inner rotating groove at its end that is opened on the end face of the pressure roller, and the T-shaped column can rotate relative to the pressure roller; A columnar rod is fixedly installed at the end of the T-shaped column away from the pressure roller, and a U-shaped block is rotatably fitted into the annular groove on the outer wall of the columnar rod; The lower end of the first movable rod is movably connected to the U-shaped block by a pin, and the upper end of the first movable rod is movably connected to the second movable rod by a pin. The end of the second movable rod is fixedly installed with a fixing rod, and the surface of the fixing rod is fixedly installed with a first cylinder that is fixedly installed with the mounting plate. Two guide rail rods are fixedly installed on the inner wall of the mounting port by fixing blocks. The inner wall of the guide rail rod is slidably set with the end of the column rod away from the T-shaped column.

[0008] Preferably, the upper surface of the pressure roller is at the same horizontal level as the upper surface of the belt. The pressure roller is made of rubber, and its upper surface is flush with the belt surface, ensuring that the packaging box can be smoothly transferred to the pressure roller without jamming or shifting. The rubber material has both elasticity and friction, which not only prevents damage to the packaging box, but also ensures a tight fit when folding the edges, improving the neatness of the folds.

[0009] Preferably, the track opening on the inner wall of the guide rail is provided by a combination of inclined surface, arc surface and plane. The track opening composed of inclined surface, arc surface and plane can guide the column rod to move smoothly - the inclined surface makes it easy for the column rod to enter, the arc surface reduces movement friction and avoids jamming, and the plane ensures movement stability. Ultimately, this makes the vertical movement of the roll forming edge assembly more precise and the edge folding consistency stronger.

[0010] Preferably, a position sensor is installed between the two guide rails on the surface of the mounting plate above the pressure roller. The position sensor is connected to the first cylinder signal, and the position sensor above the pressure roller is also connected to the first cylinder signal. This allows for real-time detection of the packaging box position and synchronous triggering of the first cylinder to control the pressure roller action, achieving automated and precise control of the folding edge, reducing manual intervention, improving efficiency, and lowering the error rate.

[0011] Preferably, the positioning component includes: The second cylinder is vertically fixedly mounted on the surface of the mounting plate, and the piston rod of the second cylinder is fixedly mounted with a clamping plate. The guide rail post is fixedly installed at its end to the surface of the mounting plate, and the guide rail post is slidably disposed with the clamping plate; The positioning plate is fixedly installed on the top surface of the mounting bracket with the mounting opening. The second cylinder drives the clamping plate to move, which, together with the positioning plate on the top surface of the mounting bracket, can clamp the packaging box and prevent it from shifting during folding. The guide rail column restricts the movement direction of the clamping plate to avoid the clamping plate from tilting, ultimately ensuring that the packaging box is accurately positioned and the folding position is without deviation.

[0012] This utility model provides a packaging box folding mechanism. This packaging box folding mechanism has the following advantages: This packaging box folding mechanism offers precise positioning and high efficiency: the positioning component clamps the packaging box to prevent displacement during folding and ensures accurate folding position; the position sensor is linked with the cylinder to achieve automated folding control, reducing manual intervention and improving work efficiency.

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0016] like Figure 1-6 As shown, this utility model provides a technical solution: a packaging box folding mechanism, comprising: Mounting frame 1 extends laterally, and two mounting frames 1 are arranged in pairs and parallel. Two symmetrically arranged brackets 2 are fixedly installed on the bottom surface of mounting frame 1. The brackets 2 are H-shaped. The two symmetrical H-shaped brackets 2 on the bottom surface of mounting frame 1 can enhance the overall support stability of the mechanism and avoid the impact of shaking on the conveying accuracy and folding quality during operation. The mounting bracket 1 has a mounting plate 4 fixedly mounted on its top surface, and the top surface of the mounting bracket 1 located at the rear has a mounting opening 7. A conveying mechanism 3 is installed between the two mounting brackets 1; The roller-type folding assembly 5 is installed between the mounting plate 4 and the conveying mechanism 3. The roller-type folding assembly 5 can move vertically relative to the belt in the conveying mechanism 3. The roll-pressed hemming assembly 5 includes: The pressure roller 51 is positioned parallel to the belt at the mounting opening 7; The T-shaped column 59 is rotatably configured with the inner rotating groove 8 opened at the end face of the pressure roller 51, and the T-shaped column 59 can rotate relative to the pressure roller 51. A columnar rod 52 is fixedly installed at the end of the T-shaped column 59 away from the pressure roller 51, and a U-shaped block 54 is rotatably sleeved in the annular groove opened on the outer wall of the columnar rod 52; The lower end of the first movable rod 55 is movably connected to the U-shaped block 54 by a pin, and the upper end of the first movable rod 55 is movably connected to the second movable rod 56 by a pin. The end of the second movable rod 56 is fixedly installed with a fixing rod 57, and the surface of the fixing rod 57 is fixedly installed with the first cylinder 58, which is fixedly installed with the mounting plate 4. There are two guide rail rods 53, which are fixedly installed on the inner wall of the mounting port 7 by fixing blocks. The inner wall of the guide rail rod 53 is slidably set with the end of the column rod 52 away from the T-shaped column 59. The track opening of the inner wall of the guide rail rod 53 is composed of inclined surface, arc surface and plane. The track opening composed of inclined surface, arc surface and plane can guide the column rod 52 to move smoothly - the inclined surface makes it easy for the column rod 52 to enter, the arc surface reduces the friction of movement and avoids jamming, and the plane ensures the stability of movement. Ultimately, it makes the vertical movement of the roll forming edge assembly more precise and the edge consistency stronger.

[0017] Here, the upper surface of the pressure roller 51 is at the same level as the upper surface of the belt. The pressure roller 51 is made of rubber, and its upper surface is flush with the belt surface, ensuring that the packaging box can smoothly transition to the pressure roller 51 without jamming or shifting. The rubber material has both elasticity and friction, which not only prevents damage to the packaging box, but also ensures a tight fit when folding the edge, improving the neatness of the fold.

[0018] A position sensor (not shown in the figure) is installed on the surface of the mounting plate 4 above the pressure roller 51 between the two guide rail rods 53. The position sensor is connected to the first cylinder 58. The position sensor above the pressure roller 51 is also connected to the first cylinder 58. This allows for real-time detection of the packaging box position and synchronous triggering of the first cylinder 58 to control the pressure roller's movement. This enables automated and precise control of the folding process, reduces manual intervention, improves efficiency, and lowers the error rate.

[0019] Positioning component 6 is installed between two mounting plates 4. Positioning component 6 can move vertically along the belt and is used to position and clamp the packaging box that needs to be folded.

[0020] Positioning component 6 includes: The second cylinder 61 is vertically fixedly installed on the surface of the mounting plate 4, and the piston rod of the second cylinder 61 is fixedly installed with a clamping plate 63. The guide rail post 62 is fixedly installed at its end to the surface of the mounting plate 4, and the guide rail post 62 is slidably disposed with the clamping plate 63. The positioning plate 64 is fixedly installed on the top surface of the mounting frame 1 with the mounting port 7. The second cylinder 61 drives the clamping plate 63 to move. The positioning plate 64 on the top surface of the mounting frame 1 can clamp the packaging box to prevent displacement during folding. The guide rail column 62 restricts the movement direction of the clamping plate 63 to prevent the clamping plate 63 from tilting, and ultimately ensures that the packaging box is accurately positioned and the folding position is without deviation.

[0021] When the packaging box folding mechanism is in use, the packaging box to be folded is first conveyed forward by the conveying mechanism 3 installed between two parallel mounting frames 1. When the packaging box moves to the corresponding position of the positioning component 6, the second cylinder 61, which is vertically fixed to the surface of the mounting plate 4, is activated. Its piston rod drives the clamping plate 63 to slide along the guide rail column 62, cooperating with the positioning plate 64 fixed to the top surface of the mounting frame 1 with the mounting opening 7, to clamp and position the packaging box to prevent displacement. Subsequently, after the position sensor on the surface of the mounting plate 4 above the pressure roller 51 detects the packaging box, it immediately sends a signal to the first cylinder 58 fixed to the mounting plate 4. The first cylinder 58 drives the second movable rod 56 to move through the fixed rod 57. The second movable rod 56 then... Pulling the first movable rod 55, which is hinged to it, causes the lower end of the first movable rod 55 to move the cylindrical rod 52 via the U-shaped block 54 connected by a pin. The end of the cylindrical rod 52 away from the T-shaped column 59 slides along the inclined surface, arc surface, and plane trajectory of the inner wall of the guide rail rod 53. At the same time, the T-shaped column 59 at the other end of the cylindrical rod 52 rotates in the inner rotating groove 8 on the end face of the pressure roller 51, thereby driving the pressure roller 51 to move vertically relative to the belt of the conveying mechanism 3, and performing roller pressing and folding on the positioned packaging box. After the folding is completed, the first cylinder 58 resets and drives the pressure roller 51 to rise, and the second cylinder 61 resets and drives the clamping plate 63 to move up and release the packaging box. Finally, the conveying mechanism 3 transports the folded packaging box to the next process, completing a single folding operation.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above.

Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
