[0035] The following is combined with Figure 1-3 This application is described in further detail.

[0036] The embodiment of the present application discloses an adjustable sealing packaging device.

[0037] Reference Figure 1 and Figure 2 An adjustable sealing packaging device comprises a frame 1, a bag-making device 6 mounted on the frame 1, and a sealing packaging device 3. The bag-making device 6 is used to fold a single-layer packaging film (i.e., the raw material of the wet wipes packaging bag) to form a packaging tube with a cylindrical structure. The sealing packaging device 3 is used to seal the opening of the paper towel package after the wet wipes are packaged. During the packaging process of paper towels or wet wipes, the packaging tube (i.e., the raw material of the packaging bag) moves horizontally relative to the frame 1. The bag-making device 6 and the sealing packaging device 3 are sequentially arranged along the moving direction of the packaging tube to complete the automatic packaging of paper towels or wet wipes.

[0038] Reference Figure 2 and Figure 3The sealing and packaging device 3 includes two heat sealing knives 31 arranged in a vertical direction, and the two heat sealing knives 31 can move closer to or farther from each other. The sealing and packaging device 3 also includes a driving mechanism 32 for driving the two heat sealing knives 31 to move, and the driving mechanism 32 includes a driving disk 321, and the driving disk 321 is arranged on one side of the heat sealing knife 31 in a direction horizontally and perpendicular to the moving direction of the packaging tube. The driving disk 321 is rotatably connected to the mounting frame 2, and the rotation direction of the driving disk 321 is horizontal and perpendicular to the moving direction of the packaging tube. The heat sealing knife 31 is rotatably connected to the driving disk 321, and the rotation of the driving disk 321 can drive the heat sealing knife 31 to move along a circular trajectory, and then can drive the heat sealing knife 31 to produce displacement in the vertical and horizontal directions. The position of the heat sealing knife 31 in the vertical direction can make the two heat sealing knives 31 move closer to or farther from each other. The horizontal displacement of the heat sealing knife 31 enables the heat sealing knife 31 to move with the packaging tube, thereby increasing the contact time between the heat sealing knife 31 and the packaging tube and improving the heat sealing effect of the heat sealing knife 31 on the end of the packaging tube.

[0039] Reference Figure 2 and Figure 3 The driving mechanism further includes a gear set 322, which includes two gears meshing with each other, and the two gears are respectively connected to the driving disk 321, so as to drive the two driving disks 321 to rotate synchronously, so as to facilitate synchronous control of the movement of the two heat sealing knives 31.

[0040] Reference Figure 2 and Figure 3 One of the heat sealing knives 31 is equipped with a cutter 33, which is located in the middle of the heat sealing knives 31 in a direction parallel to the moving direction of the packaging tube. A cutting groove 34 is provided on the other heat sealing knives 31 corresponding to the cutter 33, and the cutter 33 can be inserted into the cutting groove 34. When the two heat sealing knives 31 seal the packaging bags, two adjacent packaging bags can be divided, thereby improving production efficiency.

[0041] Reference Figure 2 and Figure 4 A mounting frame 2 is provided between the sealing and packaging device 3 and the frame 1, and the mounting frame 2 is slidably connected to the frame 1 in the vertical direction. The sliding mounting frame 2 can adjust the vertical position of the sealing and packaging device 3, so that when the sides of the two heat-sealing knives of the sealing and packaging device 3 are close to each other, they are located in the middle position of the packaging bag in the vertical direction, thereby ensuring the sealing and packaging equipment to seal packaging bags of different specifications and improving the application range of the sealing and packaging equipment.

[0044] Reference Figure 2 and Figure 4 The sliding member 4 includes a connecting portion 41 and an abutting portion 42. The abutting portion 42 is plate-shaped, and is located on the side of the first connecting plate 21 away from the support plate 11, and abuts against the first connecting plate 21. The connecting portion 41 is integrally formed and arranged on the side of the abutting portion 42 close to the support plate 11. The first connecting plate 21 is provided with a waist-shaped hole 12 disposed on the ground in the length direction. The connecting portion 41 is inserted into the waist-shaped hole 12 and can slide relative to the first connecting plate 21 along the length direction of the waist-shaped hole 12. The side of the connecting portion 41 away from the abutting portion 42 is fixedly connected to the support plate 11 to realize the sliding connection between the mounting frame 2 and the frame 1.

[0045] Reference Figure 2 and Figure 4 , the sliding member 4 on the support plate 11 or the support seat 13 can be set to multiple. The sliding of the mounting frame 2 is limited by multiple sliding members 4, thereby improving the stability of the mounting frame 2 during the sliding process. In this embodiment, four sliding members 4 are provided on the upper support plate 11, and two sliding members 4 are provided on the support seat 13. In this embodiment, the sliding of the mounting frame 2 is driven by a cylinder, and in other embodiments, it can also be driven by other mechanisms, such as a linear module.

Figure 5 The limiting assembly 5 includes a locking member 51, which is slidably connected to the support plate 11 in a direction perpendicular to the support plate 11. The locking member 51 includes a locking plate 511 and a pull rod 512. The locking plate 511 is located on the side of the first connecting plate 21 away from the support plate 11. One end of the pull rod 512 is locked on the locking member 511, and the other end passes through the waist-shaped hole 12 and is slidably connected to the support plate 11.

[0047] Reference Figure 2 and Figure 5 The limiting assembly 5 also includes a driving member 52 for driving the locking member 51 to move. The driving member 52 is installed on the support plate 11 to drive the pull rod 512 to slide. In this embodiment, the driving member 52 is a cylinder. The sliding direction of the cylinder piston rod is perpendicular to the sliding direction of the locking member 51 to facilitate the installation of the cylinder. A linkage assembly 8 is arranged between the piston rod of the cylinder and the locking member 51. The linkage assembly 8 includes a mounting seat 82 and an inclined block 81. The mounting seat 82 is fixedly connected to the frame 1, and the pull rod 512 is slidably connected to the mounting seat 82. The outer shell of the cylinder is fixedly connected to the mounting seat 82, and the piston rod of the cylinder is fixedly connected to the inclined block 81. A first inclined surface 83 is provided on the inclined block 81, and the first inclined surface 83 is inclined along the sliding direction of the piston rod of the cylinder from the side close to the cylinder to the side away from the cylinder towards the direction close to the locking member 51. A second inclined surface 84 is provided on the pull rod 512 to fit with the first inclined surface 83. When the piston rod drives the inclined block 81 to move in the direction away from the cylinder, the locking member 51 can be driven to approach and press against the mounting frame 2 under the action of the first inclined surface 83 and the second inclined surface 84, thereby realizing the locking of the sliding of the mounting frame 2.

[0048] Reference Figure 2 and Figure 5 The piston rod of the cylinder drives the pull rod 512 to slide, thereby driving the locking piece 511 to move closer to or away from the first connecting plate 21. After the locking piece 511 is pressed against the first connecting plate 21, the sliding of the mounting frame 2 is limited under the action of friction, thereby improving the stability of the mounting frame 2 during the sealing and packaging process.

[0049] Reference Figure 2 and Figure 4 The locking member 51 is located on one side of the sliding member 4. In this embodiment, the locking member 51 is arranged directly below the sliding member 4. A guide groove 43 is provided on the sliding member 4 at a position corresponding to the locking piece 511. The side wall of the locking piece 511 is fitted with the side wall of the guide groove 43. The guide groove 43 runs through the sliding direction of the locking member 51. The locking piece 511 can slide in accordance with the side wall of the guide groove 43. The sliding of the locking piece 511 is guided and limited by the guide groove 43, thereby improving the stability of the locking piece 511 during the sliding process.

[0050] Reference Figure 2 and Figure 4 The limiting components 5 are arranged in multiple groups corresponding to the sliding members 4 to improve the stability of limiting the sliding of the mounting frame 2.

[0051] Reference Figure 1 and Figure 6During the wet wipes packaging process, the wet wipes are arranged at intervals along the moving direction of the packaging tube before passing through the traction component 61. At the same time, the two edges of the packaging tube partially overlap, and the overlapping part is defined as the side seal. A conveying plate 65 is provided on the frame 1, and the conveying plate 65 is located above the bag making device 6. The conveying plate 65 is provided with an avoidance groove, and the side seal of the packaging tube extends through the avoidance hole toward the direction close to the bag making device 6. The bag making device 6 includes a traction component 61, a heating component 62, an extrusion component 63 and a shearing component 64. The traction component 61 is used to drive the packaging tube to move, and the heating component 62 is used to heat and connect the side seal. The extrusion component 63 is used to further extrude the side seal to improve the stability of the connection between the two sides of the packaging tube. The shearing component 64 is used to cut the excess part of the side seal to make the side seal more neat.

[0052] Reference Figure 6 The traction assembly 61 includes two clamping wheels 611, which are respectively arranged on both sides of the trajectory line of the moving direction of the packaging tube. The clamping wheels 611 are driven by a servo motor.
