[0035] Please also read Figures 1 to 6 Now, a high-speed transverse sealing device for a packaging machine provided in an embodiment of the present application is described. The high-speed transverse sealing device for a packaging machine includes a wall panel 100, a heat sealing component and a driving component. Among them:

[0036] The heat sealing assembly is connected to the wall panel 100 and two groups are arranged at intervals. The heat sealing assembly includes an upper crossbeam 201 and an upper heat sealing mold 202 installed on the upper crossbeam 201, and also includes a lower crossbeam 203 spaced apart from the upper crossbeam 201 and a lower heat sealing mold 204 installed on the lower crossbeam 203; the driving assembly includes a toggle shaft 301 respectively connected to the upper crossbeam 201 and the lower crossbeam 203, and an archway 302 erected on both sides of the heat sealing assembly, a roller 303 is coaxially rotated on the toggle shaft 301, a cam groove 304 for providing a rolling guide for the roller 303 is arranged on the archway 302, and the roller 303 is used to roll synchronously in the cam groove 304 so that the upper heat sealing mold 202 and the lower heat sealing mold 204 in the two groups of heat sealing assemblies can be synchronously approached or synchronously moved away.

[0037] According to the above structure provided in the present embodiment, two groups of heat sealing components are arranged in the high-speed transverse sealing device of the packaging machine provided in the present embodiment. Since the driving component used to drive the upper heat sealing mold 202 and the lower heat sealing mold 204 in the heat sealing component to move closer or farther away adopts a structure in which the roller 303 and the cam groove 304 cooperate with each other, when the roller 303 connected to the two groups of heat sealing components rolls synchronously, the upper heat sealing mold 202 and the lower heat sealing mold 204 in the two groups of heat sealing components can be driven to move closer or farther synchronously, so that the two groups of heat sealing components in the high-speed transverse sealing device of the packaging machine in the present embodiment can perform the sealing operation synchronously, which greatly improves the heat sealing efficiency and is far superior to the prior art. In addition, since the roller 303 can move quickly in the cam groove 304, it can also play a technical effect of further improving the heat sealing efficiency.

[0038] In another embodiment of the present application, please refer to Figures 1 to 6 The driving assembly includes a driving shaft 305 that passes through the arch 302 from the center of the cam groove 304 and is parallel to the toggle shaft 301, a turntable 306 coaxially connected to the driving shaft 305 and blocks the roller 303 in the cam groove 304, and a slide plate 307 that is slidably connected to the turntable 306 and is used to move radially along the turntable 306; a notch 308 is provided on the turntable 306 for the toggle shaft 301 to pass through, and one end of the slide plate 307 close to the notch 308 is mounted on the toggle shaft 301.

[0039] According to the above structure provided in the present embodiment, when the driving shaft 305 rotates, the turntable 306 can be driven to rotate. Since the toggle shaft 301 passes through the notch 308 set on the turntable 306, the turntable 306 can drive the toggle shaft 301 to rotate around the axis of the turntable 306 through the sliding 307, thereby driving the roller 303 to roll in the cam groove 304. In this process, since the movement of the toggle shaft 301 is restricted by the slide plate 307 mounted on the toggle shaft 301 and the slide plate 307 is used to move along the radial direction of the turntable 306, the toggle shaft 301 and the upper heat sealing mold 202 and the lower heat sealing mold 204 connected to the toggle shaft 301 can only move along the radial direction of the turntable 306. In this way, the upper heat sealing mold 202 and the lower heat sealing mold 204 in the two groups of heat sealing components in the present embodiment can have better synchronization and faster moving speed, which is beneficial to further improve the heat sealing efficiency of the high-speed horizontal sealing device of the packaging machine in the present embodiment. It should be noted that the notch 308 provided on the rotating disk 306 in this embodiment is not only for the driving shaft 301 to pass through, but also needs to enable the driving shaft 301 to move within a certain range. Therefore, in the actual production process, the size of the notch 308 needs to be flexibly set according to the moving range of the driving shaft 301, which will not be repeated here.

[0040] In another embodiment of the present application, please refer to Figures 1 to 6 , the driving assembly also includes a first linear rail 309 and a first slider 310 slidably connected to the first linear rail 309; the first linear rail 309 is fixedly connected to the lower crossbeam 203 in one group of heat sealing assemblies and is slidably connected to the lower crossbeam 203 in another group of heat sealing assemblies through the first slider 310. According to the above structure provided in this embodiment, the lower crossbeams 203 in the two groups of heat sealing assemblies can be connected through the first linear rail 309 to maintain better synchronization, and at the same time, mechanical interference can be avoided, which is conducive to further improving the heat sealing efficiency of the high-speed horizontal sealing device of the packaging machine in this embodiment. The significance of setting the lower crossbeam 203 in one group of heat sealing assemblies to be connected to the first linear rail 309 through the first slider 310 is that it can better adapt to the movement of the toggle shaft 301 to avoid motion interference.

[0041] In another embodiment of the present application, please refer to Figures 1 to 6The driving assembly also includes a second linear rail 311 perpendicular to the first linear rail 309 and a second slider 312 slidably connected to the second linear rail 311. The second linear rail 311 is fixedly connected to the lower crossbeam 203 and slidably connected to the upper crossbeam 201 through the second slider 312. The second linear rail 311 is parallel to the direction in which the upper heat-sealing mold 202 and the lower heat-sealing mold 204 approach or move away from each other. According to the above structure provided in this embodiment, the process in which the upper heat-sealing mold 202 and the lower heat-sealing mold 204 approach or move away from each other can be guided by the second linear rail 311, so that the speed of the upper heat-sealing mold 202 and the lower heat-sealing mold 204 approaching or moving away from each other can be faster and more stable, which is conducive to further improving the heat sealing efficiency of the high-speed horizontal sealing device of the packaging machine in this embodiment.

[0042] In another embodiment of the present application, please refer to Figures 1 to 6 The drive assembly also includes a third linear rail 313 connected to the arch 302 and a third slider 314 slidably connected to the third linear rail 313; the third linear rail 313 is parallel to the first linear rail 309, and the second linear rail 311 is connected to the third slider 314 via a fourth slider 321 slidably fitted to itself. According to the above structure provided in this embodiment, the third linear rail 313 can cooperate with the first linear rail 309 to increase the stability of the second linear rail 311, which is beneficial to further improve the heat sealing efficiency of the high-speed horizontal sealing device of the packaging machine in this embodiment. Similarly, it can be understood that the second linear rail 311 is slidably connected to the third linear rail 313 through the fourth slider 321 and the third slider 314 to avoid motion interference between the second linear rail 311 and the movement of the toggle shaft 301. Please refer to the following for details. Figure 6 Here, a connecting seat or a connecting block is usually provided between the fourth slider 321 and the third slider 314 to complete the connection between the two.

[0044] In another embodiment of the present application, please refer to Figures 1 to 6 Guide blocks 316 are connected to both sides of the slide plate 307, and the slide plate 307 is slidably connected to the turntable 306 through the guide blocks 316.

According to the above structure provided in this embodiment, the straight section 317 is provided on the side where the cam grooves 304 are close to each other, which is conducive to the roller 303 to keep moving in a straight line on the straight section 317, so that the upper heat sealing mold 202 and the lower heat sealing mold 204 can always keep in contact during the straight movement of the roller 303, prolonging the heat sealing time of the packaging bag body, which is conducive to the high-speed horizontal sealing device of the packaging machine in the embodiment to form a better heat sealing effect.

[0046] In another embodiment of the present application, please refer to Figures 1 to 6 The driving assembly also includes a driving gear 318 rotatably mounted on the arch 302 and a passive gear 319 sleeved on the driving shaft 305.
