[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5As shown, this utility model proposes a width-adjustable packaging machine sealing device, including a bag clamping mechanism 3. The bag clamping mechanism 3 includes a mounting base 35, on which at least one sealing block 2 is slidably disposed. The sealing block 2 has a mounting groove 21 that slidably engages with the mounting base 35. A clamping block 24 is disposed on one side of the mounting groove 21, which is used to limit the position of the sealing block 2 on the mounting base 35. The bag clamping mechanism 3 can adapt to packaging bags of different widths. Specifically, the sealing block 2 in the bag clamping mechanism 3 is slidably disposed on the mounting base 35 through the mounting groove 21, and the user can adjust the position of the sealing block 2 according to the actual width of the packaging bag. When the sealing block 2 moves to the appropriate position, the clamping block 24 fixes the sealing block 2 on the mounting base 35, ensuring its stability during the sealing process. This adjustment process is simple and intuitive, and can quickly match packaging bags of different specifications, thereby completing an effective sealing operation.

[0028] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the mounting base 35 is provided with fifth inclined portions 351 on both sides, the mounting base 35 has an inverted trapezoidal cross-section, one side of the mounting groove 21 is provided with a first inclined portion 22 that slides with the fifth inclined portion 351, and one side of the clamping block 24 is provided with a third inclined portion 25 that slides with the fifth inclined portion 351. When the sealing block 2 slides along the mounting base 35 to adjust its position, the first inclined portion 22 and the fifth inclined portion 351 maintain a close sliding contact. Similarly, the third inclined portion 25 on the clamping block 24 also slides with the fifth inclined portion 351. This inclined structure design ensures that the sealing block 2 has good guidance and stability during sliding, while the clamping block 24 can more firmly lock the sealing block 2 in the desired position.

[0029] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a fourth inclined portion 26 is provided on one side of the clamping block 24, and a second inclined portion 23 is provided on one side of the mounting groove 21 to slide in cooperation with the fourth inclined portion 26. The inclination direction of the third inclined portion 25 is opposite to the inclination direction of the fourth inclined portion 26. The clamping block 24 has a strip-shaped through groove 27, and the sealing block 2 has a threaded hole 28. The strip-shaped through groove 27 is used to accommodate fasteners, the fasteners being bolts, which pass through the strip-shaped through groove 27 and are threadedly connected to the threaded hole 28. The clamping block 24 can achieve self-locking and guiding functions when moving up and down. When the clamping block 24 moves upward, it is guided by the second inclined portion 23, forcing the clamping block 24 to move towards the mounting base 35, so that it fits tightly against the surface of the mounting base. Furthermore, the slot 27 on the clamping block 24 engages with the threaded hole 28 on the sealing block 2, and is connected and fixed in position by fasteners. This allows the clamping block 24 to gradually press against the mounting base 35 during its ascent, achieving a secure lock on the sealing block 2. This enhances the tightness of contact between the clamping block 24 and the mounting base 35, preventing loosening or displacement, and improving the stability and reliability of the sealing process.

[0030] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the bag clamping mechanism 3 includes a horizontal plate 31, on which a guide rail 32 is mounted. At least one slide block 33 is slidably engaged with the guide rail 32, and a sliding plate 34 is mounted on the slide block 33. The sliding plate 34 is fixedly connected to the mounting base 35. The bag clamping mechanism 3 further optimizes the adjustment method of the sealing block 2. Through the sliding engagement of the slide block 33 on the guide rail 32, the user can flexibly adjust the position of the mounting base 35, thereby adjusting the relative position of the sealing block 2 and the packaging bag, ensuring the accuracy and adaptability of the sealing operation.

[0031] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a support rod is installed at the bottom of the horizontal plate 31. One end of the support rod is connected to a drive mechanism 1. The drive mechanism 1 includes a base plate 11, a transmission shaft 12 is rotatably connected to the base plate 11, a swing arm 13 is mounted on the transmission shaft 12, and transmission rods 15 are hinged to both ends of the swing arm 13. One end of the transmission rod 15 is hinged to the support rod, and the support rod is slidably connected to the base plate 11. Two bag clamping mechanisms 3 are slidably connected to the base plate 11, and the two bag clamping mechanisms 3 are respectively hinged to the transmission rods 15 at both ends of the swing arm 13. The drive mechanism 1 can drive the two bag clamping mechanisms 3 to move synchronously, realizing automated bag sealing operation. When the transmission shaft 12 rotates, the swing arm 13 swings accordingly, pushing the support rod to slide on the base plate 11 through the transmission rods 15, thereby driving the bag clamping mechanism 3 to reciprocate along the guide rail direction. Since the two bag clamping mechanisms 3 are respectively connected to the two ends of the swing arm 13, they can move synchronously in opposite directions or in opposite directions to complete actions such as clamping and sealing bags.

[0032] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a gear 14 is fixedly connected to one end of the transmission rod 15. The transmission rod 15 is driven to rotate by the gear 14. The gear 14 meshes with a gear set or rack output from an external power source. When the power source is started, the gear 14 is driven to rotate, and drives the transmission rod 15 to rotate synchronously. Through the cooperation of the gear 14 and the transmission system, precise control of the direction, speed and stroke of the bag clamping mechanism can be achieved, thereby completing automated operations such as bag clamping and sealing.

[0033] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the base plate 11 is equipped with a slide rail, and one end of the support rod is slidably engaged with the slide rail. When the drive mechanism is working, the gear 14 drives the transmission rod 15 to rotate, and the rotational motion is converted into linear reciprocating motion through the swing arm 13, pushing the support rod to slide along the slide rail. The slide rail ensures that the support rod and its connected bag clamping mechanism maintain stable directionality and parallelism during movement, avoiding deviation or swaying, thereby ensuring the accurate execution of the bag sealing action.

[0034] Example 1:

[0035] This invention proposes a width-adjustable bag-sealing device for a packaging machine, including a bag-clamping mechanism 3. The bag-clamping mechanism 3 includes a mounting base 35, on which at least one bag-sealing block 2 is slidably disposed. The bag-sealing block 2 has a mounting groove 21 that slidably engages with the mounting base 35. A clamping block 24 is disposed on one side of the mounting groove 21, which is used to limit the position of the bag-sealing block 2 on the mounting base 35. The bag-clamping mechanism 3 can adapt to packaging bags of different widths. Specifically, the bag-sealing block 2 in the bag-clamping mechanism 3 is slidably disposed on the mounting base 35 through the mounting groove 21, and the user can adjust the position of the bag-sealing block 2 according to the actual width of the packaging bag. When the bag-sealing block 2 moves to the appropriate position, the clamping block 24 fixes the bag-sealing block 2 on the mounting base 35, ensuring its stability during the sealing process. This adjustment process is simple and intuitive, and can quickly match packaging bags of different specifications, thereby completing an effective bag-sealing operation.

[0036] The mounting base 35 has a fifth inclined portion 351 on both sides. The cross-section of the mounting base 35 is an inverted trapezoidal structure. One side of the mounting groove 21 has a first inclined portion 22 that slides with the fifth inclined portion 351, and one side of the clamping block 24 has a third inclined portion 25 that slides with the fifth inclined portion 351. When the sealing block 2 slides along the mounting base 35 to adjust its position, the first inclined portion 22 and the fifth inclined portion 351 maintain a tight sliding contact. Similarly, the third inclined portion 25 on the clamping block 24 also slides with the fifth inclined portion 351. This inclined structure design ensures that the sealing block 2 has good guidance and stability during sliding, while the clamping block 24 can more firmly lock the sealing block 2 in the desired position. One side of the clamping block 24 has a fourth inclined portion 26, and one side of the mounting groove 21 has a second inclined portion 23 that slides with the fourth inclined portion 26. The inclination direction of the third inclined portion 25 is opposite to that of the fourth inclined portion 26. The clamping block 24 has a slotted groove 27, and the sealing block 2 has a threaded hole 28. The slotted groove 27 is used to accommodate fasteners, which are bolts. The fasteners pass through the slotted groove 27 and are threadedly connected to the threaded hole 28. The clamping block 24 can achieve self-locking and guiding functions when moving up and down. When the clamping block 24 moves upward, it is guided by the second inclined part 23, forcing the clamping block 24 to move towards the mounting base 35, making it tightly fit against the surface of the mounting base. Furthermore, the slotted groove 27 on the clamping block 24 cooperates with the threaded hole 28 on the sealing block 2, and the clamping block 24 is connected and fixed in position by fasteners. This allows the clamping block 24 to gradually press against the mounting base 35 during its ascent, achieving a secure lock on the sealing block 2. This enhances the tightness of contact between the clamping block 24 and the mounting base 35, preventing loosening or displacement, and improving the stability and reliability of the sealing process.

[0037] The bag clamping mechanism 3 includes a horizontal plate 31, on which a guide rail 32 is mounted. At least one slide block 33 is slidably fitted onto the guide rail 32. A sliding plate 34 is mounted on the slide block 33, and the sliding plate 34 is fixedly connected to a mounting base 35. The bag clamping mechanism 3 further optimizes the adjustment method of the sealing block 2. Through the sliding engagement of the slide block 33 on the guide rail 32, the user can flexibly adjust the position of the mounting base 35, thereby adjusting the relative position of the sealing block 2 and the packaging bag, ensuring the accuracy and adaptability of the sealing operation.

[0038] A support rod is installed at the bottom of the horizontal plate 31. One end of the support rod is connected to a drive mechanism 1. The drive mechanism 1 includes a base plate 11, a transmission shaft 12 rotatably connected to the base plate 11, and a swing arm 13 mounted on the transmission shaft 12. Transmission rods 15 are hinged to both ends of the swing arm 13, with one end of the transmission rod 15 hinged to the support rod. The support rod is slidably connected to the base plate 11. Two bag-clamping mechanisms 3 are slidably connected to the base plate 11, and each of the two bag-clamping mechanisms 3 is hinged to the transmission rods 15 at both ends of the swing arm 13. The drive mechanism 1 can drive the two bag-clamping mechanisms 3 to move synchronously, achieving automated bag sealing. When the transmission shaft 12 rotates, the swing arm 13 swings accordingly, pushing the support rod to slide on the base plate 11 via the transmission rods 15, thereby driving the bag-clamping mechanisms 3 to reciprocate along the guide rail. Since the two bag-clamping mechanisms 3 are respectively connected to both ends of the swing arm 13, they can move synchronously in opposite directions or in opposite directions to complete bag clamping and sealing actions. A gear 14 is fixedly connected to one end of the transmission rod 15. The transmission rod 15 is driven to rotate by gear 14. Gear 14 meshes with a gear set or rack output from an external power source. When the power source is started, gear 14 is driven to rotate, which in turn drives the transmission rod 15 to rotate synchronously. Through the cooperation of gear 14 and the transmission system, precise control of the direction, speed, and stroke of the bag clamping mechanism can be achieved, thereby completing automated operations such as bag clamping and sealing. A slide rail is installed on the base plate 11, and one end of the support rod slides in cooperation with the slide rail. When the drive mechanism is working, gear 14 drives the transmission rod 15 to rotate, and the rotational motion is converted into linear reciprocating motion through the swing arm 13, pushing the support rod to slide along the slide rail. The slide rail ensures that the support rod and its connected bag clamping mechanism maintain stable directionality and parallelism during movement, avoiding deviation or swaying, thereby ensuring the accurate execution of the sealing action.

[0039] Specifically, the working principle of this invention is as follows:

[0040] The bag clamping mechanism 3 can adapt to packaging bags of different widths. Specifically, the sealing block 2 in the bag clamping mechanism 3 is slidably mounted on the mounting base 35 through the mounting groove 21, and the user can adjust the position of the sealing block 2 according to the actual width of the packaging bag. The mounting base 35 has a fifth inclined part 351 on both sides, which cooperates with the first inclined part 22 on the sealing block 2 and the third inclined part 25 on the clamping block 24 to ensure the guidance and stability of the sliding process. The clamping block 24 cooperates with the second inclined part 23 through the fourth inclined part 26 to achieve a self-locking function when moving up and down. When the clamping block 24 is pressed by the fastener, it can automatically fit into the mounting base 35 and firmly lock the position of the sealing block 2.

[0041] The bag clamping mechanism 3 further enhances its adjustment flexibility through a sliding structure consisting of a horizontal plate 31, a guide rail 32, a slide block 33, and a sliding plate 34. The slide block 33 can slide on the guide rail 32, driving the sliding plate 34 and the mounting base 35 to move together, thereby adjusting the relative position of the entire bag sealing assembly and the packaging bag to ensure the accuracy of the sealing operation. The bottom of the horizontal plate 31 is connected to a support rod and is driven by a drive mechanism 1. The drive mechanism 1 includes a base plate 11, a transmission shaft 12, a swing arm 13, and a transmission rod 15. It receives power through a gear 14 and drives the transmission rod 15 to rotate, which in turn drives the swing arm 13 to swing, converting the rotational motion into linear reciprocating motion.

[0042] Under the action of the drive mechanism 1, the transmission rod 15 pushes the support rod to slide along the slide rail on the base plate 11, driving the bag clamping mechanism 3 to move synchronously along the guide rail. The two bag clamping mechanisms 3 are respectively hinged to both ends of the swing arm 13 to achieve opposite or back-to-back movement, completing the bag clamping and sealing actions. The design of the slide rail ensures the directional stability and repeatability of the movement process, avoids deviation or shaking, and improves the equipment operating efficiency and the consistency of sealing quality.

[0043] In summary, this utility model solves the problem that traditional packaging machines cannot seal packaging bags of different widths.
