The transverse sealing device for a pillow packaging machine includes a wall panel 101, a heat sealing component and a material support member 104. Among them:

[0036] The heat sealing assembly is symmetrically arranged in two groups along the height direction of the wall panel 101. The heat sealing assembly includes a rotating shaft 102 rotatably mounted on the wall panel 101 and a heat sealing block 103 connected to the rotating shaft 102. Generally speaking, the two groups of heat sealing blocks 103 can face each other and complete the sealing work of the packaging bag during the process of following the rotating shaft 102. Figure 5 In this embodiment, four groups of heat sealing blocks 103 are provided, and the heat sealing assembly can complete four transverse seals in one rotation. The supporting member 104 is connected to the heat sealing block 103 in the lower heat sealing assembly and forms an arc-shaped supporting plate portion 105. The supporting plate portion 105 is coaxially arranged with the rotating shaft 102 and is located behind the heat sealing block 103 in the rotating direction of the rotating shaft 102.

[0037] According to the above structure provided in the present embodiment, when the transverse sealing device of the pillow packaging machine in the present embodiment is used for heat-sealing packaging bags, the supporting member 104 connected to the heat-sealing block 103 can support the packaging bags being heat-sealed. Since the supporting plate portion 105 of the supporting member 104 is in an arc shape coaxial with the rotating shaft 102, the packaging bags can be stably supported during the heat-sealing process, which significantly improves the sealing quality of the transverse sealing device of the pillow packaging machine in the present embodiment, which is far superior to the prior art.

[0038] In another embodiment of the present application, please refer to Figures 1 to 6 The support member 104 also includes a connecting plate portion 106 connected to the support plate portion 105, and a waist-shaped groove 107 extending radially along the rotating shaft 102 is provided on the connecting plate portion 106. The support member 104 is connected to the heat sealing block 103 through a fastener that can pass through the waist-shaped groove 107. According to the above structure provided in this embodiment, the support member 104 can adjust the distance relative to the rotating shaft 102 in the radial direction of the rotating shaft 102 through the waist-shaped groove 107 provided on the connecting plate portion 106. In this way, the support member 104 provided in this embodiment can be better adapted to packaging bags of different packaging thicknesses, so that the lifting height of the packaging bag by the support member 104 can be better adapted to the sealing height of the heat sealing block 103, which is conducive to further improving the sealing quality of the horizontal sealing device of the pillow packaging machine in this embodiment.

[0039] In another embodiment of the present application, please refer to Figures 1 to 6 At least two sets of supporting plate portions 105 arranged in parallel are connected to the connecting plate portion 106.

According to the above structure provided in this embodiment, the height of the wall panel 101 can be flexibly adjusted by rotating the screw 111 relative to the nut seat 110, so that the height of the heat sealing assembly installed on the wall panel 101 can be more flexibly adjusted, which is conducive to making the horizontal sealing device of the pillow packaging machine provided in this embodiment applicable to more working scenarios.

[0041] In another embodiment of the present application, please refer to Figures 1 to 6 The adjustment mechanism also includes a side plate 112 connected to the base 108 and parallel to the screw 111, and the side plate 112 is slidably connected to the wall plate 101.

According to the above structure provided in this embodiment, the slidably connected guide rod 114 and guide sleeve 113 are conducive to further improving the stability of the wall panel 101 in the height adjustment process of this embodiment.

[0043] In another embodiment of the present application, please refer to Figures 1 to 6 The adjustment mechanism also includes a worm 115 perpendicular to the screw 111 and a worm wheel 116 fixedly connected to the screw 111 and drivingly connected to the worm 115. According to the above structure provided in this embodiment, the worm 115 arranged perpendicular to the screw 111 and drivingly connected to the screw 111 through the worm wheel 116 can change the adjustment direction of the screw 111 by the operator, which is conducive to making the horizontal sealing device of the pillow packaging machine provided in this embodiment have a more flexible and convenient height adjustment effect.

[0044] In another embodiment of the present application, please refer to Figures 1 to 6One end of the worm 115 is connected to an adjusting hand wheel 117. According to the above structure provided in this embodiment, the adjusting hand wheel 117 connected to the worm 115 can significantly reduce the difficulty of rotating the worm 115, which is conducive to making the horizontal sealing device of the pillow packaging machine provided in this embodiment have a more flexible and convenient height adjustment effect.

[0045] In another embodiment of the present application, please refer to Figures 1 to 6 The transverse sealing device of the pillow packaging machine also includes a top plate 118 connected to the wall plate 101 and a sliding seat 119 slidably connected to the wall plate 101. The heat sealing component located above in the height direction of the wall plate 101 is connected to the sliding seat 119 and can be driven by the sliding seat 119 to approach the heat sealing component located below. A spring 120 is connected between the sliding seat 119 and the top plate 118, and the deformation direction is parallel to the relative movement direction of the two groups of heat sealing components. According to the above structure provided in this embodiment, the distance of the sliding seat 119 relative to the top plate 118 and the spacing between the two groups of heat sealing components can be elastically adjusted by the spring 120. In this way, when packaging bags of different packaging thicknesses pass through the interval between the two groups of heat sealing components, the spring 120 can be adaptively contracted so that the heat sealing blocks 103 in the two groups of heat sealing components can better heat seal the packaging bags, thereby facilitating the transverse sealing device of the pillow packaging machine provided in this embodiment to be applicable to more working scenarios.

[0046] In another embodiment of the present application, please refer to Figures 1 to 6 The heat sealing assembly also includes a rotating plate 121 coaxially connected to both ends of the rotating shaft 102 and a support beam 122 connected to the heat sealing block 103. The rotating plate 121 is provided with a slide groove 123 along the radial direction of the rotating shaft 102. Connecting shafts 127 are extended at both ends of the support beam 122. The support beam 122 is slidably connected to the rotating plate 121 through a slide seat 129 rotatably mounted on the connecting shaft 127 and cooperating with the slide groove 123. Usually, a guide groove 130 is provided on the slide seat 129 to cooperate with both sides of the slide groove 123 on the rotating plate 121 to limit the axial freedom of the support beam 122.

[0047] The outer ends of the connecting shaft 127 are connected to two rollers 124 through roller seats 128, and the center lines of the two rollers 124 are parallel to the working surface of the heat sealing block 103. Two groups of cam grooves 125 for the rollers 124 to roll are correspondingly formed on the sliding seat 119 and the wall panel 101, and the two groups of cam grooves 125 form parallel straight sections 126 on the side close to each other.

[0048] According to the above structure provided in this embodiment, when the rotating shaft 102 rotates, it can drive the roller 124 to roll in the cam groove 125 on the wall plate 101. When the roller 124 rolls to the straight section 126 of the cam groove 125, the heat sealing blocks 103 in the two groups of heat sealing components can maintain the same linear speed as the packaging bag within a certain time range and move along with the packaging bag, so that the heat sealing block 103 and the packaging bag can form a longer contact time and achieve better sealing quality of the horizontal sealing device of the pillow packaging machine in this embodiment. It can be understood that when the roller 124 runs to the straight section 126 of the cam groove 125, the support beam 122 can adaptably move in the slide groove 123 set on the rotating plate 121 and rotate with the connecting shaft 127 as the rotating shaft and make the working surfaces of the two paired heat sealing blocks 103 parallel to each other, so as to ensure the stable heat sealing.
