Technical Field

[0001] This utility model relates to the field of product sealing technology, and in particular to a one-line sealing machine for hygiene products. Background Technology

[0002] Against the backdrop of the booming development of the health industry, the hygiene product market is experiencing rapid growth, with demand for disposable hygiene products such as diapers, sanitary napkins, and medical masks continuing to rise. As a crucial link in the production and distribution of hygiene products, the sealing process directly affects product quality protection, transportation safety, and end-delivery efficiency. Proper sealing not only effectively isolates external contamination and ensures product hygiene and safety, but it is also a vital guarantee for the rapid flow of products from the production workshop to the consumer end. Its efficiency and quality have a profound impact on a company's market competitiveness.

[0003] However, some hygiene product manufacturers still use the traditional manual sealing method. This method relies mainly on manual labor for tasks such as folding carton lids, applying tape, and smoothing. In practice, this method has revealed numerous drawbacks: Firstly, manual sealing is inefficient and cannot meet the high-efficiency demands of modern large-scale production, especially during peak order seasons, easily leading to delivery delays and impacting the company's reputation and market share. Secondly, manual sealing is highly dependent on the number of workers; with the continuous rise in labor costs in recent years, companies' labor expenditures in the sealing process have been increasing, significantly compressing profit margins. Furthermore, manual operation lacks stability and consistency, resulting in inconsistent sealing quality. Problems such as loose tape or improper lid folding can lead to product damage and contamination risks during transportation. Under the trend of intelligent and automated upgrading in the hygiene product industry, the traditional manual sealing method has become a bottleneck restricting companies from reducing costs, increasing efficiency, and improving quality. There is an urgent need to develop new, efficient, and stable sealing technologies and equipment to meet the industry's high-quality development needs. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1 to 9 As shown;

[0029] A one-line box sealing machine for hygiene products includes a base plate 1. A U-shaped bracket 2 is fixedly connected to the upper surface of the base plate 1. A box sealing assembly 3 is arranged inside the U-shaped bracket 2. The box sealing assembly 3 includes a connecting plate 32 arranged above the base plate 1 and two rotating shafts 33 fixedly connected to one side of the connecting plate 32. Each rotating shaft 33 has an inclined plate 34 fitted on its surface. A connecting shaft 311 is inserted into a circular hole on the surface of the inclined plate 34. A second disc 38 and a first disc 35 are fixedly connected to both ends of the connecting shaft 311, respectively. A triangular rod 36 is fixedly connected to the side of the first disc 35 away from the arc-shaped through groove 39. Two guide rods 313 arranged symmetrically are fixedly connected inside the U-shaped bracket 2.

[0030] In this implementation plan: the basic framework of the one-line carton sealing machine for hygiene products is constructed. The base plate 1 provides stable support for the entire carton sealing machine. The U-shaped bracket 2 is fixed on the base plate 1, providing installation space and support structure for the carton sealing component 3, so that the carton sealing machine is structurally stable and can maintain a fixed position during operation.

[0031] The connecting plate 32, rotating shaft 33, inclined plate 34, connecting shaft 311, disc 2 38, disc 1 35 and triangular rod 36 of the sealing assembly 3 cooperate with each other to form a movable structure, laying the foundation for the subsequent carton sealing operation. The guide rod 313 provides guidance for the movement of the sealing assembly 3.

[0032] Furthermore:

[0033] In an optional embodiment, a counterweight 37 is fixedly connected to the side of disk 35 away from disk 38, and a counterweight 314 is fixedly connected to the bottom end of inclined plate 34.

[0034] In this implementation scheme: counterweight 37 and counterweight 314 are fixed on disc 35 and inclined plate 34 respectively. The gravity of the counterweights helps to keep disc 35 and inclined plate 34 balanced and stable during movement. This helps to ensure that the movement trajectory and angle of each component of the sealing assembly 3 are more accurate when working, and improves the accuracy and stability of the sealing operation.

[0035] Furthermore:

[0036] In an optional embodiment, a positioning shaft 310 is inserted into an arc-shaped through groove 39 inside the second disk 38. The positioning shaft 310 is rotatably connected to the second disk 38, and one end of the positioning shaft 310 is fixedly connected to the inclined plate 34.

[0037] In this implementation scheme: the positioning shaft 310 is inserted into the arc-shaped through groove 39 of the second disc 38 and is rotatably connected to the second disc 38. At the same time, one end is fixedly connected to the inclined plate 34. This structure restricts the range of motion of the second disc 38, so that it can only rotate around the positioning shaft 310 within the range allowed by the arc-shaped through groove 39, which plays a guiding and positioning role and ensures that the movement of the second disc 38 meets the requirements of the sealing operation.

[0038] Furthermore:

[0039] In an optional embodiment, an electric push rod 31 is installed in the mounting groove on the upper surface of the U-shaped bracket 2, and the end of the telescopic rod of the electric push rod 31 is fixedly connected to the connecting plate 32.

[0040] In this implementation scheme: the electric push rod 31 on the U-shaped bracket 2 provides power to the sealing assembly 3. Through the extension and retraction of the electric push rod 31, the connecting plate 32 is driven to move up and down, thereby driving the entire sealing assembly 3 to work and realize the sealing operation of the carton, thus automating the sealing process.

[0041] Furthermore:

[0042] In an optional embodiment, the rotating shaft 33 and the inclined plate 34 are rotatably connected, the connecting shaft 311 and the inclined plate 34 are rotatably connected, and the second disk 38 and the first disk 35 are both in contact with the inclined plate 34.

[0043] In this implementation scheme: the rotatable connection between the rotating shaft 33 and the inclined plate 34, and the connecting shaft 311 and the inclined plate 34, allows the inclined plate 34 to rotate flexibly around the rotating shaft 33 and the connecting shaft 311, increasing the mobility of the sealing assembly 3. The two discs 38 and the one disc 35 are in close contact with the inclined plate 34, ensuring a tight fit between the components, enabling the force to be effectively transmitted, and improving the efficiency and accuracy of the sealing operation.

[0044] Furthermore:

[0045] In an optional embodiment, a roller 312 is mounted on the bottom end of the inclined plate 34, and the roller 312 is in contact with the surface of the base plate 1.

[0046] In this embodiment: the roller 312 at the bottom end of the inclined plate 34 is in contact with the surface of the base plate 1. When the inclined plate 34 moves, the roller 312 rolls on the base plate 1, which reduces the friction between the inclined plate 34 and the base plate 1, making the movement of the inclined plate 34 smoother. At the same time, the roller 312 can also assist the inclined plate 34 in rotating, further improving the movement flexibility of the sealing assembly 3.

[0047] Furthermore:

[0048] In an optional embodiment, the bottom ends of the two guide rods 313 are respectively provided with inclined cut surfaces on opposite sides, and one side of the guide rods 313 and the inclined plate 34 are in contact with each other.

[0049] In this embodiment: the guide rod 313 is attached to the inclined plate 34. When the guide rod 313 is attached to the disc 38, the triangular rod 36 rotates to fold the paper wings of the carton. The inclined cut surface can guide the disc 38 and the guide rod 313 to attach, ensuring that the sealing assembly 3 can accurately seal the carton.

[0050] Furthermore:

[0051] In an optional embodiment, a conveying assembly 4 is provided on the surface of the base plate 1. The conveying assembly 4 includes an electric push rod 41, a crossbar 42, a motor 44, a turntable 45, and a conveyor belt 47. The conveyor belt 47 is installed in two square slots opened on the upper surface of the base plate 1, and the electric push rod 41 is installed in a receiving slot 46 opened inside the base plate 1. The end of the telescopic rod of the electric push rod 41 is fixedly connected to the crossbar 42. The motor 44 is installed on the upper surface of the crossbar 42. The end of the output shaft of the motor 44 is fixedly connected to the turntable 45. The crossbar 42 is inserted into a slot 43 opened inside the base plate 1, and the crossbar 42 and the base plate 1 are slidably connected.

[0052] In this implementation scheme: the conveying assembly 4 realizes the conveying and rotation functions of the carton, the conveyor belt 47 is used to convey the carton to the sealing position, the electric push rod 41 drives the motor 44 and the turntable 45 to move up and down through the crossbar 42, the motor 44 drives the turntable 45 to rotate, when the carton is conveyed above the turntable 45, the electric push rod 41 lifts the carton, the motor 44 makes the turntable 45 drive the carton to rotate, and cooperates with the sealing assembly 3 to complete the sealing operation on different sides of the carton, thereby improving the working efficiency and applicability of the sealing machine.

[0053] Working principle: Place the carton on the two conveyor belts 47 on the surface of the base plate 1, start the conveyor belts 47, and the carton will start to be conveyed forward until it moves directly above the turntable 45. At this time, the carton is in the initial position to be sealed.

[0054] When the electric push rod 31 in the mounting groove on the upper surface of the U-shaped bracket 2 is activated, the telescopic rod of the electric push rod 31 retracts upward, causing the connecting plate 32 to move upward. Since a rotating shaft 33 is fixedly connected to one side of the connecting plate 32, and an inclined plate 34 is sleeved on the surface of the rotating shaft 33, the upward movement of the connecting plate 32 causes the inclined plate 34 to rotate on the surface of the rotating shaft 33. The included angle between the inclined plate 34 and the connecting plate 32 gradually decreases. During this process, the roller 312 installed at the bottom end of the inclined plate 34 is attached to the surface of the base plate 1 and rotates, which plays a role in assisting the rotation of the inclined plate 34.

[0055] Because a counterweight 37 is fixedly connected to the side of disc 35 away from disc 38, and a counterweight 314 is fixedly connected to the bottom end of inclined plate 34, under the gravity of counterweight 37, the positioning shaft 310 fits against one end wall of the arc-shaped through groove 39 inside disc 38, so that disc 35 does not rotate in the initial stage. When the triangular rod 36 fits against the carton, the connecting plate 32 continues to move upward, driving the inclined plate 34 to move upward synchronously. The triangular rod 36 slides upward along the surface of the carton. When disc 38 and U-shaped bracket... When the guide rod 313 of the internal fixed connection is in contact, the guide rod 313 exerts a force on the second disk 38, causing the second disk 38 to rotate. Since the second disk 38 is connected to the first disk 35 through the connecting shaft 311, the rotation of the second disk 38 drives the first disk 35 and the triangular rod 36 to rotate synchronously, thereby folding the paper wings on both sides of the carton onto the top of the carton. After the paper wings on both sides are folded, the telescopic rod of the electric push rod 31 extends, driving the inclined plate 34 and the triangular rod 36 to reset, ready to fold the other two paper wings.

[0056] After the paper wings on both sides of the carton are folded, the electric push rod 41 in the receiving groove 46 inside the base plate 1 is activated. The telescopic rod of the electric push rod 41 moves upward, driving the crossbar 42, motor 44 and turntable 45 to move upward together, lifting the carton. At this time, the motor 44 is activated, and the output shaft of the motor 44 drives the turntable 45 to rotate 90 degrees, thereby causing the carton to rotate 90 degrees as well, exposing the unfolded paper wings of the carton, which is convenient for the sealing assembly 3 to perform subsequent operations.

[0057] Repeat the operation of the electric push rod 31, and the sealing assembly 3 folds the other two paper wings exposed after the carton is rotated, and finally completes the folding of the four paper wings of the carton, realizing the complete sealing process of the carton. Under the action of the two conveyor belts 47, the sealed carton is conveyed out.

[0058] Through the coordinated operation of the sealing assembly 3 and the conveying assembly 4, this linear carton sealing machine can efficiently and conveniently complete the sealing of cartons for hygiene products, greatly improving sealing efficiency and quality.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
