Description

Technical Field

[0001] This utility model relates to the field of packaging machinery and equipment technology, specifically to a high-speed four-sided heat-sealing packaging equipment. Background Technology

[0002] In the field of packaging machinery and equipment, four-side heat sealing technology is widely used in the production of composite packaging of paper and plastic film. It seals the edges of the material through a hot-pressing mold to form a packaging product with moisture-proof and sealing functions. Existing heat sealing equipment with structures that drive the pressure plate to raise and lower the mold mainly falls into two categories: one uses direct cam drive, where the cam is in rigid contact with the pressure plate, and the pressure plate is pushed downwards by changes in the cam profile; the other relies on linear drive using a pneumatic or hydraulic cylinder, utilizing air or hydraulic pressure to provide heat sealing pressure.

[0003] However, these traditional structures have obvious defects: when using cam direct drive, the rigid contact between the cam and the pressure plate is prone to generating large impacts, which not only aggravates component wear and shortens the service life of the equipment, but also causes instantaneous gaps between the pressure plate and the placement platform due to the impact force, reducing the fitting accuracy; if there are slight unevenness on the surface of the placement platform or fluctuations in material thickness, the rigid contact cam structure cannot make adaptive compensation, which can easily cause insufficient local heat sealing pressure, resulting in poor sealing or leakage.

[0004] While pressure regulation can mitigate impact when using pneumatic or hydraulic cylinders for heat sealing, the stability of pneumatic or hydraulic pressure is significantly affected by pipeline resistance and flow fluctuations. During heat sealing, pressure is prone to momentary attenuation or fluctuations, causing instability in the fit between the pressure plate and the placement platform. This problem is amplified, especially in high-speed, continuous operations, affecting not only the consistency of the sealed product's quality but also reducing production efficiency due to frequent equipment maintenance. Therefore, improving the fit between the pressure plate and the placement platform during heat sealing and reducing impact wear to ensure stable heat sealing quality has become a pressing technical challenge for existing four-sided heat sealing equipment. Utility Model Content

[0005] To overcome the above-mentioned defects, the present invention provides a high-speed four-sided heat-sealing packaging equipment, which solves the technical problem in the prior art where the poor fit between the pressure plate and the placement table during heat sealing affects the heat sealing quality.

[0006] According to one aspect, at least one embodiment of the present invention provides a high-speed four-side heat-sealing packaging device, comprising:

[0007] frame,

[0008] A placement table, which is horizontally arranged on the frame, is used to place paper and plastic film.

[0009] A pressure plate is raised and lowered on the frame and located above the placement table. A mold is provided at the lower end of the pressure plate. The pressure plate can move downward to allow the mold to heat-press the paper and plastic film on the placement table.

[0010] A rotating shaft is rotatably mounted on the frame and located above the pressure plate. An eccentric bearing is connected to the rotating shaft, and the eccentric bearing can rotate coaxially with the rotating shaft.

[0011] The first telescopic component is disposed on the pressure plate, and the extended end of the first telescopic component abuts against the outer wall of the eccentric bearing. The eccentric bearing can rotate to cause the first telescopic component to be subjected to pressure and press against the pressure plate.

[0012] For example, at least one embodiment of the present invention provides a high-speed four-sided heat-sealing packaging device that also includes a heating plate. The heating plate is disposed on the upper end of the mold and can heat the mold so that the mold can heat-seal paper and plastic film after being heated.

[0013] For example, at least one embodiment of the present invention provides a high-speed four-sided heat-sealing packaging device that also includes a heat insulation plate, which is disposed between the heating plate and the pressure plate, and is used to insulate the heat of the heating plate.

[0014] For example, at least one embodiment of the present invention provides a high-speed four-sided heat-sealing packaging device that also includes a second telescopic component. The second telescopic component is disposed on the frame, and the end of the second telescopic component is connected to the pressure plate. The second telescopic component enables the pressure plate to rise and move away from the placement platform.

[0015] For example, at least one embodiment of the present invention provides a high-speed four-side heat-sealing packaging device, which also includes a moving platform, with two ends of the moving platform being a loading position and a unloading position, and the frame being movably disposed between the loading position and the unloading position.

[0016] For example, in at least one embodiment of the present invention, a high-speed four-sided heat-sealing packaging device is provided with a pusher on the moving platform, which is used to push the frame to slide.

[0017] For example, in a high-speed four-sided heat-sealing packaging device provided in at least one embodiment of the present invention, the rotating shaft is provided in multiple ways, evenly spaced above the pressure plate; a set of telescopic members is provided below each rotating shaft, and a set of telescopic members is provided with at least two telescopic members spaced apart.

[0018] For example, in at least one embodiment of the present invention, a high-speed four-sided heat-sealing packaging device is provided with a flexible pad on the placement table, and paper and plastic film are placed on the flexible pad;

[0019] The mold is provided with multiple sets of protrusions, each of which is a hollow ring and is used to heat-seal paper and plastic film after being heated.

[0020] For example, in at least one embodiment of the present invention, a high-speed four-sided heat-sealing packaging device is provided with an adjustment hole at the lower end of the frame. The placement platform is connected to the adjustment hole by a fastener. The adjustment hole is configured to adjust the angle of the placement platform by adjusting the amount of screwing of the fastener into the adjustment hole.

[0021] For example, at least one embodiment of the present invention provides a high-speed four-sided heat-sealing packaging device that further includes a rotation drive component, which is used to drive the rotation shaft to rotate.

[0022] The beneficial effects of this utility model are as follows:

[0023] In this invention, when the rotating shaft drives the eccentric bearing to rotate, the contact between the eccentric bearing and the first telescopic component allows pressure to be transmitted to the pressure plate through the first telescopic component. The elastic characteristics of the first telescopic component can buffer pressure fluctuations during the transmission process and simultaneously achieve elastic compensation. When there are slight unevennesses on the surface of the placement table or differences in the thickness of the material to be heat-sealed, the first telescopic component can adjust the stress state of the pressure plate by its own extension and retraction, ensuring that the mold always maintains a tight fit with the paper and plastic film on the placement table. This ensures uniform pressure distribution in the heat-sealing area, avoids quality problems such as insecure local heat sealing or missed sealing due to insufficient fit, significantly improves the stability of heat sealing quality, reduces the impact when the pressure plate contacts the placement table, reduces wear on equipment components caused by rigid collisions, extends the service life of the equipment, and ensures operational stability during high-speed continuous operation, further improving the overall working efficiency of the equipment.

[0037] like Figures 1-4 As shown, this invention illustrates a high-speed four-sided heat-sealing packaging device according to one embodiment. The frame 1 serves as the basic support structure of the device. The placement platform 2 is bolted to the horizontal platform surface of the frame 1, forming a bearing plane. The pressure plate 3 is connected to the frame 1 via a guide rail assembly. The guide rail extends vertically, allowing the pressure plate 3 to slide back and forth along the guide rail. The mold 4 is mounted on the lower end face of the pressure plate 3. The rotating shaft 5 is mounted on the top of the frame 1 via a bearing seat. The axis of the rotating shaft 5 is parallel to the upper surface of the placement platform 2. The inner ring of the eccentric bearing 51 is interference-fitted with the rotating shaft 5, and the outer circumferential surface of the outer ring contacts the telescopic end of the telescopic component 6. The telescopic component 6 is connected to the upper surface of the pressure plate 3, and the axis of the telescopic component 6 is perpendicular to the upper surface of the pressure plate 3.

[0038] During operation, an external power source drives the rotating shaft 5 to rotate, and the eccentric bearing 51 rotates synchronously with the rotating shaft 5. When the farthest point of the outer ring of the eccentric bearing 51 turns towards the telescopic component 6, the telescopic component 6 is subjected to axial pressure and undergoes compression deformation. The pressure is transmitted to the pressure plate 3 through the telescopic component 6, causing the pressure plate 3 to move downward along the guide rail. The mold 4 gradually approaches the paper and plastic film on the placement table 2 and finally completes the hot pressing. When the closest point of the outer ring of the eccentric bearing 51 turns towards the telescopic component 6, the pressure of the telescopic component 6 is released, and under the action of the external reset structure, the pressure plate 3 moves upward and resets.

[0039] In this structure, the combination of the rotating shaft 5 and the eccentric bearing 51 converts the rotational motion into the linear motion of the pressure plate 3, and the downward distance of the pressure plate 3 is controlled by the eccentricity. The telescopic component 6 provides elastic buffering during pressure transmission. When there are micro-unevennesses or uneven material thicknesses on the surface of the placement platform 2, the deformation of the telescopic component 6 can be adaptively adjusted to ensure that the contact pressure between each part of the mold 4 and the material is consistent.

[0040] The heating plate 7 is connected to the upper surface of the mold 4, and its terminals are connected to an external temperature control system via wires. During operation, the heating plate 7 generates heat when energized, which, through heat conduction, raises the temperature of the mold 4 to the preset heat-sealing temperature. When the mold 4 comes into contact with the material, heat is transferred to the contact edges of the paper and plastic film, causing the plastic film to melt and bond with the paper. The heating plate 7 allows for controllable temperature control of the mold 4, solving the problem of uneven heating caused by traditional molds relying on external heat sources, ensuring stable heat-sealing temperature, and improving the consistency of heat-sealing strength.

[0041] The heat insulation plate 8 is fixed between the heating plate 7 and the pressure plate 3. The heat insulation plate 8 can block the heat transfer from the heating plate 7 to the pressure plate 3, and prevent the pressure plate 3 from deforming due to long-term heating.

[0042] In this example, the telescopic component 9 can be a cylinder or a helical spring. When the telescopic component 9 is a cylinder, the cylinder body is mounted on the side support of the frame 1, and the piston rod end is connected to the side of the pressure plate 3 via a connecting bracket. The axis of the telescopic component 9 is parallel to the guide rail. When the pressure plate 3 needs to be reset, the piston rod of the telescopic component 9 retracts, causing the pressure plate 3 to move upward; when the pressure plate 3 moves downward, the piston rod of the telescopic component 9 extends synchronously. The telescopic component 9 provides a stable reset force for the pressure plate 3, matching the motion cycle of the pressure plate 3 with the rotation cycle of the shaft, thus improving the coordination of equipment operation.

[0043] When the telescopic component 9 uses an elastic element (such as a coil spring), one end of the spring is hooked to the crossbeam of the frame 1, and the other end is hooked to the upper surface of the pressure plate 3, with the spring in a pre-stretched state. When the pressure plate 3 moves downward, the spring is further stretched, storing elastic potential energy; when the heat sealing is completed and the pressure of the telescopic component 6 is released, the elastic potential energy of the spring is converted into tension, pulling the pressure plate 3 upward to reset. The elastic element does not require an external power source, has a simple structure, and low maintenance costs. By selecting springs with different stiffness coefficients, it can adapt to pressure plates 3 of different weights. Its reset force increases linearly with the amount of stretching, avoiding rigid impact on the pressure plate 3 during reset. It is suitable for scenarios where the reset speed requirement is not high but the structure needs to be simplified.

[0044] The upper surface of the moving table 10 is equipped with a slide rail extending along its length. The slider at the bottom of the frame 1 cooperates with the slide rail to form a sliding pair. The loading and unloading positions are respectively located at both ends of the moving table 10. The loading position is equipped with a material positioning mechanism, and the unloading position is equipped with a finished product conveying mechanism. The frame 1 can move between the two positions along the slide rail. When the frame 1 is at the loading position, the placement table 2 receives the material to be heat-sealed; when the frame 1 moves to the unloading position, the heat-sealed product is transferred to the conveying mechanism. This structure enables parallel operation of heat sealing and loading / unloading, reducing equipment downtime and increasing output per unit time.

[0045] The pusher 11 can be a hydraulic cylinder. The cylinder body of the pusher 11 is fixed to the end of the moving table 10. The piston rod is connected to the side of the frame 1 through a connecting seat. The axis of the pusher 11 is parallel to the slide rail. When the pusher 11 extends or retracts, the frame 1 slides along the slide rail by pushing and pulling the piston rod. Its stroke is controlled by a limit switch to ensure that the frame 1 stops accurately at the loading or unloading position.

[0046] Multiple rotating shafts 5 are evenly distributed along the length of the pressure plate 3, with equal axial spacing between adjacent rotating shafts 5. The number of eccentric bearings 51 on each rotating shaft 5 is the same as the number of corresponding telescopic components 6, and the eccentric bearings 51 on the same rotating shaft 5 are in phase. When multiple rotating shafts 5 rotate synchronously, each set of telescopic components 6 simultaneously applies pressure to the pressure plate 3, ensuring that the force points on the pressure plate 3 are evenly distributed. Compared with single rotating shaft 5 driving, this avoids bending deformation of the pressure plate 3 caused by concentrated force, ensures that the lower surface of the mold 4 remains parallel to the placement table 2, and improves the flatness of the heat sealing.

[0047] A flexible pad 12 is laid on the upper surface of the placement table 2. The flexible pad 12 can be made of silicone, and its edges are aligned with the edges of the placement table 2. The protrusions 41 on the lower end face of the mold 4 correspond to the four-sided contours of the product to be heat-sealed. The cross-section of the protrusions 41 is a continuous arrangement of rectangles, and the hollow area corresponds to the internal area of ​​the product. Each rectangle corresponds to the edge contour of a heat-sealed product. Its main functions are as follows: when the pressure plate 3 drives the mold 4 downward to contact the material on the placement table 2, multiple protrusions 41 can simultaneously contact the paper and plastic film at the corresponding positions. Through the heat transferred by the heating plate 7 and the pressure applied by the pressure plate 3, multiple products are heat-sealed synchronously. This structure eliminates the need for repositioning after each heat-sealing, reduces the idle travel time of the equipment, and significantly increases the product processing capacity per unit time, making it particularly suitable for mass production scenarios.

[0048] During heat sealing, the protrusion 41 contacts the flexible pad 12. The flexible pad 12 undergoes localized deformation under pressure, making the contact between the protrusion 41 and the material tighter, while preventing damage caused by excessive compression of the material. The hollow annular structure reduces the area of ​​the heat-sealing region, reducing energy consumption and avoiding thermal damage to unnecessary areas.

[0049] The adjustment hole 13 is a threaded hole distributed along the edge of the horizontal platform surface of the frame 1, and the fastener is a combination of bolts and nuts. The bottom of the placement platform 2 has a through hole corresponding to the adjustment hole 13. The bolt passes through the through hole and the adjustment hole 13 and is then locked by the nut. When the nut is loosened, the angle of the placement platform 2 in the horizontal direction can be adjusted to make the upper surface of the placement platform 2 parallel to the lower surface of the mold 4. After adjustment, the nut is tightened again. This structure solves the problem of the placement platform 2 and the mold 4 not being parallel due to installation errors of the frame 1, ensuring that the heat sealing pressure is evenly distributed in all areas.

[0050] A bevel gear, coaxial with the output shaft of the rotary drive 14, is connected to it. A bevel gear is also mounted on the rotating shaft 5. The two bevel gears mesh. When the rotary drive 14 starts, the bevel gear on the output shaft rotates coaxially with the output shaft. During meshing, torque is transmitted through the friction between the tooth surfaces, causing the power of the rotary drive 14 to be transmitted to the rotating shaft 5 via the bevel gear pair. This bevel gear transmission structure can change the direction of power transmission, making the installation position of the rotary drive 14 more flexible. It does not need to be coaxially arranged with the rotating shaft 5, saving installation space at the top of the frame 1. Simultaneously, the meshing transmission of bevel gears features precise transmission ratio and high efficiency. Compared to belt or chain drives, it reduces slippage or lag during power transmission, ensuring a strict proportional relationship between the rotational speed of the rotating shaft 5 and the output speed of the rotary drive 14, further guaranteeing the stability of the lifting frequency of the pressure plate 3. Furthermore, both bevel gears are treated with hardened tooth surfaces, and the meshing points are lubricated with lubricating oil, reducing tooth surface wear, extending the service life of transmission components, and ensuring long-term stable operation of the equipment.

[0051] In the initial state, the pressure plate 3 is in the upper position, maintaining the maximum distance from the placement table 2, and the frame 1 is stopped at the loading position of the moving table 10. The operator or the automatic feeding mechanism places the paper and plastic film to be heat-sealed on the flexible pad 12 of the placement table 2, ensuring that the edges of the material are aligned with the positioning marks on the placement table 2. Subsequently, the pusher 11 is activated, and the piston rod extends to drive the frame 1 to move along the slide rail of the moving table 10 towards the heat-sealing station. When the frame 1 reaches the preset position, the limit switch triggers a signal, the pusher 11 stops moving, and the frame 1 completes the positioning.

[0052] Next, the drive unit 14 is activated, and its output shaft drives the rotating shaft 5 to rotate via a coupling. The eccentric bearing 51 rotates synchronously with the rotating shaft 5. When the farthest point of the outer ring of the eccentric bearing 51 turns towards the telescopic member 6, the telescopic member 6 is compressed under pressure, pushing the pressure plate 3 downward along the guide rail of the frame 1. At the same time, the piston rod of the telescopic member 9 retracts synchronously. During this process, the heating plate 7 is energized and heats up. The heat is transferred to the protrusion 41 through the mold 4, raising the temperature of the protrusion 41 to the preset heat-sealing temperature. As the pressure plate 3 continues to descend, the protrusion 41 of the mold 4 gradually approaches the material on the placement table 2, eventually contacting the flexible pad 12 and applying pressure. The flexible pad 12 is compressed and undergoes local deformation, ensuring that the protrusion 41 fits tightly against the edge of the material, completing the four-sided heat sealing.

[0053] After heat sealing is completed, the rotating shaft 5 continues to rotate. The outer ring of the eccentric bearing 51, closest to the telescopic component 6, is turned towards the telescopic component 6. The pressure of the telescopic component 6 is released, and the piston rod of the telescopic component 9 retracts, causing the pressure plate 3 to move upward and reset, separating the mold 4 from the material. At this time, the pushing component 11 moves in the opposite direction, moving the frame 1 to the unloading position. The operator or the automatic unloading mechanism removes the heat-sealed product from the placement table 2, and the frame 1 returns to the loading position to enter the next work cycle.

[0054] Throughout the process, the heat insulation plate 8 blocks the heat transfer from the heating plate 7 to the pressure plate 3, multiple rotating shafts 5 apply pressure evenly through the telescopic component 6, the adjustment hole 13 ensures that the placement platform 2 is parallel to the mold 4, and the sensor monitors the operating status of each component in real time to ensure stable and efficient operation of the equipment.
