The linkage unit comprises a transmission spline shaft 141, which is rotatably mounted on the positioning slide 123, a gear set 3 is arranged between the transmission spline shaft 141 and the corresponding transmission pulley 2 143 on the positioning slide 123, a gear set 4 is arranged between the transmission spline shaft 141 and the corresponding transmission pulley 2 143 on the pressing slide 146, and both the gear set 3 and the gear set 4 comprise a transmission bevel gear 1 144 and a transmission bevel gear 2 145, the transmission bevel gear 1 144 is respectively fixedly connected to the corresponding transmission pulley 2 143, the transmission bevel gear 2 145 is respectively rotatably mounted on the corresponding positioning slide 123 and the pressing slide 146, the transmission spline shaft 141 is fixedly connected to the corresponding transmission bevel gear 2 145 on the positioning slide 123, and the transmission spline shaft 141 and the corresponding transmission bevel gear 2 145 on the pressing slide 146 form a spline sliding fit.

[0049] When the pressing slide 146 slides relative to the adjusting slide 124, the transmission bevel gear 145 on the pressing slide 146 slides relative to the transmission spline shaft 141, driving the transmission spline shaft 141 to rotate, and under the action of the transmission bevel gear 144 and the transmission bevel gear 145, the transmission pulley 143 rotates synchronously, and the transmission pulley 143 on the adjusting slide 123 and the transmission pulley 143 on the pressing slide 146 rotate in the same direction.

[0050] A transmission group 2 is arranged between the traction group 122 on the positioning slide 123 and the transmission pulley 136 on the positioning slide 123 that is closest to the traction group 122, that is, a transmission group 2 is arranged between the two ends of the conveying roller 2 that is closest to the conveying group 102 in the traction group 122 on the positioning slide 123 and the transmission pulley 136 that is closest to the traction group 122, respectively. The transmission group 2 includes an auxiliary belt 137 and two pulleys, and the auxiliary belt 137 is arranged between the corresponding two pulleys. The two pulleys in the transmission group are fixedly mounted on the corresponding end of the conveying roller 2 and the corresponding transmission pulley 136, respectively.

[0051] The conveying roller in the driving traction group 122 rotates, and under the action of the transmission group 2, the transmission pulley 1 136 rotates synchronously.

[0052] A supporting center plate 131 is fixedly provided on the positioning slide 123, and the supporting center plate 131 is used for auxiliary support of the packaging film. Auxiliary rollers 129 are rotatably installed at the ends of the positioning slide 123 and the positioning slide 2 124 closest to the conveying group 102, and the auxiliary rollers 129 are used for adjusting the position of the packaging film. The upper end surface of the hot pressing wheel 132 on the positioning slide 123, the upper surface of the supporting side plate 130, the upper surface of the supporting center plate 131, the upper surface of the traction group 122, and the upper end surface of the auxiliary roller 129 are on the same plane.

[0053] A support plate 116 is also fixedly installed on the bottom plate 101. The support plate 116 is located between the conveying group 2 103 and the sealing assembly. A splitting electric cylinder 121 is fixedly installed on the lower surface of the support plate 116. A splitting slide 120 is fixedly installed on the piston rod end of the splitting electric cylinder 121. A hot pressing splitting knife 119 is fixedly installed on the splitting slide 120. The hot pressing splitting knife 119 is used to cut the packaging film by hot pressing.

[0054] Working principle: In the initial position, the positioning slide 123 and the positioning slide 2 124 are located at the farthest positions apart. At this time, the auxiliary slide 107 is located at the farthest position from the conveying group 102, that is, the two double-headed auxiliary screw rods 113 are located at the upper and lower sides of the conveying group 102. Then, the two packaging film reels to be used are placed on the two double-headed auxiliary screw rods 113 respectively, and the position of the reels on the double-headed auxiliary screw rod 113 is adjusted so that the reels are located at the center position of the double-headed auxiliary screw rod 113. Then, the two fixed circular plates 114 on the double-headed auxiliary screw rod 113 are used to fix the reels.

[0055] According to the width of the film on the reel, the shift motor 128 is started. Under the action of the shift motor 128, the distance between the two adjustment slides 142 and the distance between the two supporting side plates 130 are adjusted, that is, the distance between the two relatively arranged hot pressing wheels 132 is adjusted, and finally the distance between the farthest surfaces of the two relatively arranged hot pressing wheels 132 is made smaller than the width of the packaging film.

[0056] Then the packaging film on the reel below the conveying group 102 is manually pulled, and the packaging film can be unwound by the unwinding motor 115, first passing over the auxiliary roller 129 on the positioning slide 123, and then the upper surface of the supporting side plate 130 and the supporting center plate 131, and then passing through the traction group 122 on the positioning slide 123 to move to the top of the support plate 116, repeat the above steps, so that the end of the packaging film on the reel above the conveying group 102 is also moved to the top of the support plate 116, and then the splitting electric cylinder 121 is started to make the splitting slide 120 move downward, that is, the hot pressing splitting knife 119 presses and fixes the two packaging film ends on the support plate 116. At this time, the hot pressing splitting knife 119 is not started, so it will not cause the hot pressing of the packaging film on the support plate 116 to be disconnected.

[0057] Restarting the positioning motor 117 causes the positioning slide 123 and the positioning slide 124 to move towards each other, and finally causes the positioning slide 123 to contact the L-shaped limit plate 125 and cannot move further. Then starting the auxiliary motor 109 causes the auxiliary slide 107 to return to the initial position, that is, the two double-headed auxiliary screw rods 113 return to the upper and lower sides of the side sealing assembly, thereby preventing the film on the reel from contacting the conveyor belt in the conveying group 102, causing damage to the packaging film.

[0058] Continue to start the positioning motor 117 so that the positioning slide 124 continues to move downward, that is, adjust the distance between the two traction groups 122, and adjust the distance between the two traction groups 122 according to the thickness of the diapers to be packaged. At this time, the packaging film on the positioning slide 123 is located above the supporting side plate 130 and the supporting center plate 131, and then start the pressing motor 152 to adjust the position of the pressing slide 146 on the positioning slide 124, that is, make the hot pressing wheel 132 on the pressing slide 146 contact with the corresponding hot pressing wheel 132 on the positioning slide 123. At this time, the two packaging films are stacked between the two hot pressing wheels 132, and then start the traction motor 127 so that the traction group 122 pulls and conveys the packaging film, and the dividing slide 120 returns to the initial position. Under the action of the transmission group 2, the hot pressing wheels 132 rotate synchronously, and the displacement of the hot pressing wheels 132 and the traction group 122 are equal. At this time, start the hot pressing wheels 132 to heat seal the edges of both sides of the packaging film.

[0059] The diapers to be packaged are sequentially placed between the two limiting side plates 106 on the conveying group 102, and the diapers on the conveying group 102 can be stacked according to the needs, and the conveying motor 104 and the conveying motor 2 105 are started to make the conveying group 102 and the conveying group 2 103 convey the diapers, and the diapers on the conveying group 102 are conveyed to the position between the two packaging films on the side sealing assembly, and the movement of the diapers is assisted by the supporting side plates 130 and the supporting center plate 131, and then the diapers are moved to the area between the two traction groups 122, and the diapers continue to move to the support plate 116 following the packaging film, and then the diapers are moved to the area between the two traction groups 122. When the pants are about to approach the hot pressing and cutting knife 119, the cutting electric cylinder 121 is started to make the hot pressing and cutting knife 119 move downward, so that the hot pressing and cutting knife 119 cuts the end position of the packaging film by hot pressing. When the diaper moves to the outside of the hot pressing and cutting knife 119, the cutting electric cylinder 121 is started again to make the hot pressing and cutting knife 119 move downward, and the tail of the packaging film is cut by hot pressing again. Under the action of the hot pressing and cutting knife 119, the packaging films at both ends of the diaper are in a heat-sealed state, and the packaged diapers that are hot-pressed and cut by the hot pressing and cutting knife 119 fall to the conveying group 2 103, and the packaged diapers can be transported by the conveying group 2 103.

[0060] Repeat the above steps to achieve continuous packaging of diapers.

[0061] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
