Description

Technical Field

[0001] This invention relates to the field of plastic sealing equipment technology, and more particularly to an intelligent TSM ultrasonic sealing device for plastic packaging. Background Technology

[0002] The intelligent TSM ultrasonic sealing equipment for plastic packaging is a key precision piece of equipment in modern packaging production lines. Its core function is to achieve efficient, clean, and high-strength sealing of plastic packaging materials. This equipment utilizes an ultrasonic generator to produce high-frequency electrical energy, which is converted into mechanical vibration of the same frequency by a transducer and transmitted to the welding head. When the welding head applies specific pressure to the sealing area of ​​the plastic packaging, the molecules generate instantaneous high temperatures due to intense friction, causing the contact surfaces of the two plastic layers to rapidly melt and fuse together. After the pressure is removed, the seal cools and solidifies, forming a strong, aesthetically pleasing, and highly airtight seal. Compared to traditional heat sealing methods, its biggest advantage lies in its highly concentrated energy, with heating time in the millisecond range. The heat only acts on an extremely thin area of ​​the seal, without damaging the contents of the packaging, making it particularly suitable for heat-sensitive products. Its intelligence is reflected in the integration of advanced sensors and a control system, which can monitor and precisely control key parameters such as vibration frequency, amplitude, and time in real time, ensuring the consistency and reliability of each seal's quality, and automatically adjusting to adapt to films of different thicknesses and materials. This equipment not only significantly improves production efficiency and reduces energy consumption, but also eliminates the risk of product leakage and contamination caused by poor sealing, providing reliable quality assurance for industries with high cleanliness requirements such as food, pharmaceuticals, and electronics.

[0003] Traditional ultrasonic sealing equipment is widely used in the plastic sealing industry, but due to limitations in its structure and working principle, it often suffers from some unavoidable problems. Existing ultrasonic sealing equipment for plastic packaging exhibits two major limitations in application. First, it has poor adaptability to variations in plastic bag thickness. When the bag's thickness varies due to wrinkles, overlapping sealing areas, or uneven material composition, thinner or single-area areas may bear excessive pressure, easily causing material damage or melting through, severely affecting packaging sealing performance and yield. Second, pressure regulation and uniformity control are another major challenge. Traditional equipment often uses integral mechanical pressure application, which is cumbersome to adjust and cannot guarantee uniform pressure distribution between the welding head and the bag body. This often results in insufficient pressure at the edges and excessive pressure in the center, leading to inconsistent sealing strength. These problems not only increase production losses but also limit the equipment's responsiveness to diverse and high-precision packaging needs. Summary of the Invention

[0004] In view of the problems of existing technology, such as the inability of sealing equipment to adapt to the thickness of different parts of plastic bags and the inconvenience of adjusting the sealing pressure, an intelligent TSM ultrasonic sealing device for plastic packaging is proposed.

[0007] Furthermore, the telescopic unit includes a push rod disposed at the top of the outer shell near the toothed ring, and a rack disposed at the bottom of the push rod, the rack being engaged with the toothed ring;

[0008] The rotating block drives the sleeve to rotate while rotating, the sleeve drives the damping strip to rotate, the damping strip drives the toothed ring to rotate through friction, and the toothed ring drives the top rod to move horizontally through the rack. Different toothed rings remain coaxial under the action of corresponding limiting rings and limiting grooves, and adjacent toothed rings can rotate relative to each other while remaining coaxial.

[0009] Furthermore, a through hole is provided at one end of the toothed ring near the limiting ring, and an arc plate is provided on the side of the damping strip away from the sleeve, the curvature of the arc plate matching the curvature of the inner wall of the through hole.

[0010] Furthermore, the inner wall of the outer shell on the side closer to the rotating block is adaptively rotatably connected to the nearest limiting groove, and the inner wall of the outer shell on the side farther from the rotating block is adaptively rotatably connected to the nearest limiting ring.

[0011] Furthermore, the sleeve has a cylindrical cavity inside, and an expansion hole extends from the outer wall of the sleeve into the cavity.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Example 1, referring to Figures 1-13This invention provides a first embodiment of an intelligent TSM (Total Shock Muting) ultrasonic sealing device for plastic packaging, comprising a sealing machine body 1, a welding head 2 fixedly connected to the bottom of the sealing machine body 1, a pressure head 3 fixedly connected to one end of the sealing machine body 1 near the welding head 2, and an adjustment mechanism 4 installed on the bottom side of the pressure head 3 near the welding head 2. The adjustment mechanism 4 includes a housing 41 fixedly connected to the bottom side of the pressure head 3 near the welding head 2, a sleeve 42 rotatably connected inside the housing 41, both ends of the sleeve 42 rotatably connected to the inner wall of the housing 41, several expansion holes 43 arranged in a ring array on the outer wall of the sleeve 42, and damping strips 44 slidably connected to the inner wall of the expansion holes 43. A rotating block 45 is attached to the end of the sleeve 42 away from the expansion hole 43. Several toothed rings 46 are linearly arrayed and sleeved on the outside of the damping strip 44. A limiting ring 47 is fixedly connected to the toothed ring 46 on the side away from the rotating block 45. A limiting groove 48 is opened on the side of the toothed ring 46 away from the limiting ring 47. The limiting ring 47 corresponding to the toothed ring 46 is rotatably connected to the adjacent limiting groove 48. A telescopic unit is assembled on the outer shell 41 near the top of the toothed ring 46. The telescopic unit is used to apply pressure to the plastic bag. An expansion unit is assembled inside the sleeve 42. The expansion unit is used to drive the toothed ring 46 to rotate. A locking unit is assembled on the bottom of the inner wall of the outer shell 41. The locking unit is used to lock the telescopic unit.

[0037] Specifically, rotating the rotating block 45 causes the sleeve 42 to rotate as well. The sleeve 42, through the expansion hole 43, causes the damping strip 44 to rotate as well. Simultaneously, the rotation of the damping strip 44, through friction, causes all the toothed rings 46 to rotate. The rotation of the toothed rings 46, in turn, causes the corresponding toothed racks 410 to move. The toothed racks 410 then cause the corresponding push rods 49 to move. The different push rods 49 are mutually constrained, therefore they can only move horizontally towards or away from the welding head 2. When the push rod 49 is obstructed from moving towards the welding head 2, and the resistance is greater than the friction between the damping strip 44 and the toothed rings 46, slippage will occur between the toothed rings 46 and the damping strip 44. At this point, the rotation of the damping strip 44 will not cause the toothed rings to move. 46 rotates to move the plastic bag to the sealing station in the correct posture. Control the pressure head 3 to drive the adjustment mechanism 4 to move towards the welding head 2 to the maximum stroke. At this time, the push rod 49 on the adjustment mechanism 4 is not in contact with the plastic bag. By rotating the sleeve 42, the push rod 49 is driven to extend until the end of the push rod 49 close to the welding head 2 squeezes the plastic bag until the resistance of the push rod 49 is greater than the friction between the damping block and the toothed ring 46. When the sealing lines of the plastic bag are stacked with different numbers of layers, resulting in different thicknesses, the push rod 49 aligned with the thicker part moves a shorter distance and stops moving. The push rod 49 aligned with the thinner part needs to move a longer distance before stopping. However, the pressure applied to the plastic bag by the push rod 49 in different positions is the same.

[0038] Reference Figures 1-9The telescopic unit includes a push rod 49 slidably connected to the top of the outer shell 41 near the toothed ring 46, and a rack 410 fixedly connected to the bottom of the push rod 49. The rack 410 meshes with the toothed ring 46. The rotating block 45 rotates while driving the sleeve 42 to rotate. The sleeve 42 drives the damping strip 44 to rotate. The damping strip 44 drives the toothed ring 46 to rotate through friction. The toothed ring 46 drives the push rod 49 to move horizontally through the rack 410. Different toothed rings 46 maintain a coaxial state under the action of the corresponding limiting ring 47 and limiting groove 48. Adjacent toothed rings 46 can rotate relative to each other while maintaining coaxiality.

[0039] Specifically, the rotation of the gear ring 46 controls the extension and retraction of the rack 410, and the rack 410 drives the push rod 49 to move synchronously.

[0040] Reference Figures 4-8 The toothed ring 46 has a through hole at one end near the limiting ring 47, and the damping strip 44 has an arc plate on the side away from the sleeve 42, the curvature of the arc plate matching the curvature of the inner wall of the through hole.

[0041] Specifically, the top of the arc plate adapts to the inner wall of the toothed ring 46, thus enabling it to fit tightly against the inner wall of the arc plate.

[0042] Reference Figures 4-8 The inner wall of the outer shell 41 on the side closer to the rotating block 45 is adaptively rotatably connected to the nearest limiting groove 48, and the inner wall of the outer shell 41 on the side away from the rotating block 45 is adaptively rotatably connected to the nearest limiting ring 47.

[0043] Specifically, the outer shell 41 limits the toothed rings 46 closest to both ends of the sleeve 42 through the corresponding limiting rings 47 and limiting grooves 48, so that the whole composed of different toothed rings 46 is limited.

[0044] Reference Figures 5-7 The sleeve 42 has a cylindrical cavity inside, and the expansion hole 43 extends from the outer wall of the sleeve 42 into the cavity.

[0045] Specifically, the sleeve 42 accommodates the pull rod 411 through its internal cavity, allowing the pull rod 411 to rotate within itself.

[0046] Reference Figures 1-12 The expansion unit includes a pull rod 411 rotatably connected inside the sleeve 42, a screw hole 412 opened at the end of the rotating block 45 away from the sleeve 42, a number of short shafts 413 fixedly connected to the bottom of the damping strip 44 in a linear array, a number of truncated cones 414 fixedly connected to the outside of the pull rod 411 in a linear array, the number of truncated cones 414 being equal to the number of short shafts 413, the bottom end of the short shaft 413 abutting against the conical surface of the corresponding truncated cone 414, and a knob 415 fixedly connected to the end of the pull rod 411 near the rotating block 45.

[0047] Specifically, as the knob 415 rotates, it moves along its own axis under the action of the screw hole 412. When the pull rod 411 moves towards the knob 415, it drives the cone 414 to move together. As the cone 414 moves, it squeezes the corresponding short shaft 413 through its own conical surface, causing the short shaft 413 to drive the corresponding damping strip 44 to expand away from the pull rod 411. After the damping strip 44 expands a certain distance, its arc plate will contact the inner wall of the toothed ring 46. The greater the static friction between the arc plate and the toothed ring 46, the greater the resistance that the push rod 49 can overcome when moving towards the welding head 2, and the greater the pressure applied to the plastic bag during sealing.

[0048] Reference Figure 6 and Figure 5 The outer wall of the pull rod 411 is provided with a threaded groove near the screw hole 412, and the threaded groove is threadedly connected to the screw hole 412.

[0049] Specifically, the threaded groove constrains the pull rod 411 through the thread on the pull rod 411, so that the pull rod 411 can only move along its own axis when it rotates.

[0050] Example 2, refer to Figures 1-13 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the locking unit includes a groove 416 formed at the bottom of the inner wall of the housing 41, a plurality of sliding pairs 417 linearly arrayed and slidably connected inside the groove 416, the number of sliding pairs 417 being the same as the number of push rods 49, pressure blocks 418 symmetrically fixedly connected to the top of the sliding pairs 417, pressure grooves 419 formed at the bottom of the push rods 49, the inner wall of the pressure grooves 419 cooperating with the pressure blocks 418, a drive rod 420 threadedly connected to the inner wall of the plurality of pressure blocks 418, a worm gear 421 fixedly connected to one end of the drive rod 420 near the rotating block 45, and a worm 422 meshing with the outside of the worm gear 421.

[0051] Specifically, rotating the worm gear 422 causes the worm wheel 421 to rotate. When the worm wheel 421 rotates, it drives the drive rod 420 to rotate. At the same time, the drive rod 420 drives the sliding pair 417 to move. The sliding pair 417 is constrained by the slide groove 416 and can only move along the slide groove 416. When the two sliders in the sliding pair 417 move away from each other, the sliders drive the corresponding two pressure blocks 418 to move away from each other. After the two pressure blocks 418 move away from each other to a certain distance, they contact the inner wall of the pressure groove 419, thereby locking the top rod 49 and preventing the top rod 49 from moving. When the drive rod 420 rotates in the opposite direction, the two pressure blocks 418 corresponding to the sliding pair 417 move closer to each other, releasing the lock on the top rod 49.

[0052] Reference Figures 10-12The sliding pair 417 consists of two sliders with the same shape, and the drive rod 420 consists of several bidirectional lead screws. The bottom of the slider is adapted to the corresponding bidirectional lead screw with a threaded connection.

[0053] Specifically, while the bidirectional lead screw rotates, it drives the two sliders corresponding to the sliding pair 417 to move in opposite directions. The rest of the structure is the same as that in Embodiment 1.

[0054] Based on embodiments 1-2, the working principle of this invention is as follows: When there is a thickness difference in the area where the plastic bag needs to be sealed, the plastic bag is placed against the working surface of the welding head 2. By rotating the sleeve 42, the damping strip 44 is driven to rotate. At the same time, the damping strip 44 rotates, and the corresponding rack 410 moves through the toothed ring 46. The rack 410 drives the connected push rod 49 to move together. The sleeve 42 controls all the push rods 49 to move towards the welding head 2. After a certain distance, the push rods 49 compress the plastic bag, and the compression force is... When the frictional force between the toothed ring 46 and the damping strip 44 exceeds the limit, the push rod 49 stops moving. Once all push rods 49 have stopped moving, the worm gear 422 is rotated to make the worm wheel 421 rotate. The worm wheel 421 drives the drive rod 420 to rotate synchronously. The drive rod 420 locks the corresponding push rod 49 through the sliding pair 417. At this time, the push rod 49 in contact with the thicker part of the plastic bag and the push rod 49 in contact with the thinner part of the plastic bag extend at different angles, adapting to the thickness differences of the plastic bag during sealing. This allows for processing of different specifications of plastic bags. At this time, the locking of the push rod 49 is released by reversing the drive rod 420. Then, by rotating the drive rod 420, the push rod 49 is moved away from the pressure head 3, so that all the push rods 49 are reset. Then, plastic bags of different specifications are placed against the working surface of the welding head 2. The push rod 49 is then controlled to move towards the welding head 2 until it fits the thickness of the plastic bag. When it is necessary to adjust the sealing, the pressure applied by the push rod 49 to the plastic bag is adjusted by rotating the knob 415, which moves the pull rod 411 towards the rotating block 45. The pull rod 411 passes through the cone. 414 squeezes the short shaft 413, causing the short shaft 413 to drive the damping strip 44 to move away from the pull rod 411, thereby increasing the static friction between the damping strip 44 and the toothed ring 46. In this state, when adjusting the top rod 49 to adapt to the thickness of the plastic bag, the top rod 49 needs to apply greater pressure to the plastic bag in order to obtain sufficient reaction force to make the damping strip 44 and the toothed ring 46 slide. When the control pull rod 411 moves away from the rotating block 45, the pressure applied by the top rod 49 to the plastic bag during sealing is reduced.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
