[0030] The lower forming group 2 includes a lower mounting seat 21, and two groups of lower fixtures 22 and lower fixtures 23 are symmetrically arranged on the top of the lower mounting seat 21. A conveyor belt 28 is arranged on the top of the lower forming group 2. The two sides of the conveyor belt 28 are respectively connected to the two lower fixtures 23 for transmission. A servo motor 214 for driving the conveyor belt 28 is arranged inside the lower forming group 2.

[0031] The inner liner 3 is formed with a plurality of protrusions 31 and positioning portions 32 by bending through the lower forming group 2 and the upper forming group 1 .

[0032] Specifically, upper support arms 121 are provided at both ends of the top of the upper fixture 12, upper connecting rods 131 are provided at the top of the upper fixture 2 13, upper connecting rods 141 are provided at the top of the upper fixture 2 13, and a horizontal sliding shaft 15 and a stabilizing sliding shaft 16 located on both sides of the horizontal sliding shaft 15 are provided inside the upper mounting seat 11, two sliding bearings 151 are symmetrically sleeved on the surface of the horizontal sliding shaft 15, and a sliding bearing 2 161 is sleeved on the surface of the stabilizing sliding shaft 16, and an upper support arm 2 132 and an upper support arm 3 133 are sleeved on the surface of the upper connecting rod 131, and the two upper support arms 11 are sleeved on the surface of the upper connecting rod 131. 21 and the upper support arm 2 132 are respectively rotatably connected to the two sides of the two sliding bearings 2 161, the surface of the upper connecting rod 2 141 is sleeved with an upper support arm 4 142, the two upper support arms 3 133 and the upper support arm 4 142 are respectively rotatably connected to the two sides of the two sliding bearings 1 151, the interior of the upper mounting seat 11 is symmetrically provided with two upper shaft seats 19, the horizontal sliding shaft 15 and the stabilizing sliding shaft 16 are arranged between the two upper shaft seats 19, and the interior of the upper mounting seat 11 is also provided with a plurality of lifting sliding shafts 111 respectively sleeved with the interior of the two upper shaft seats 19, the setting of the lifting sliding shaft 111 ensures The stability of the lifting process of the upper shaft seat 19 is ensured. When the conveyor belt 17 drives the two upper fixtures 3 14 to move away from each other, the upper fixture 3 14 pulls the sliding bearing 151 located below it through the upper connecting rod 2 141 and the upper support arm 4 142. The upper support arm 3 133 on the other side of the sliding bearing 151 pulls the upper connecting rod 131. Since the angle changes when the upper support arm 4 142 pulls the upper support arm 3 133, the sliding bearing 151 is lifted up. The sliding bearing 151 lifts the upper shaft seat 19 through the horizontal sliding shaft 15. The cooperation of the sliding bearing 151 and the horizontal sliding shaft 15 ensures that the upper support arm 4 14 2 and the stability of the upper support arm three 133 during movement. When the upper connecting rod one 131 is pulled, the upper jig two 13 also moves with the upper connecting rod one 131, so that the distance between the upper jig three 14, the upper jig two 13 and the upper jig one 12 increases. When the two upper jigs 12 approach each other, the distance between the upper jig three 14, the upper jig two 13 and the upper jig one 12 shortens. Since there are upper jigs three 14 and upper jigs two 13 on both sides of the upper jig one 12, the upper jig three 14 and upper jigs two 13 on both sides of the upper jig one 12 will not drive the upper jig one 12 to move when they move away from each other or push each other.

[0033] Specifically, a slide plate 171 is provided on one side of the upper jig 3 14 away from the upper jig 2 13, and the two slide plates 171 are respectively connected to the two sides of the conveyor belt 17 for transmission.

The servo motor 18 is started to drive the conveyor belt 17 to rotate. Since the two slide plates 171 are connected to the two sides of the conveyor belt 17, the conveyor belt 17 drives the two upper fixtures 3 14 to move away from or approach each other when rotating.

[0034] Specifically, a lower connecting rod 1 221 is provided at the bottom of the lower fixture 1 22, a lower connecting rod 231 is provided at the bottom of the lower fixture 23, two lower shaft seats 27 are symmetrically provided inside the lower mounting seat 21, a screw rod 24 and a stabilizing shaft 25 located on both sides of the screw rod 24 are provided between the two lower shaft seats 27, two nut seats 241 are sleeved on the surface of the screw rod 24, one end of the nut seat 241 is hinged with an adjusting arm 242, the top ends of the two adjusting arms 242 are movably sleeved with the two lower connecting rods 1 221 respectively, and two sliding bearings 3 251 are sleeved on the surface of the stabilizing shaft 25, and the sliding bearings 3 251 are sleeved on the surface of the stabilizing shaft 25.

The servo motor 214 is started to rotate. The servo motor 214 drives the two lower fixtures 23 to move away from each other through the two slide plates 281. When the lower fixture 23 moves, the sliding bearing 3 251 is pulled by the lower connecting rod 1 221 and the lower support arm 26 thereon. The lower support arm 26 on the other side of the sliding bearing 3 251 pulls the lower connecting rod 231. The lower connecting rod 231 drives the lower fixture 23 to move. At the same time, the lower connecting rod 231 pulls one of the nut seats 241 through the adjusting support arm 242. The two lower connecting rods 231 pull the lower nut seats 241 respectively. The two nut seats 241 are moved, so that the two nut seats 241 lift the screw rod 24 up. When the screw rod 24 rises, it drives the lower shaft seat 27 to slide on the lifting slide shaft 211, thereby ensuring the stability of the screw rod 24. The servo motor 3 29 is started to drive the screw rod 24 to rotate, and the initial positions of the two nut seats 241 can be adjusted, so that the initial position between the two lower fixtures 1 22 and the lower fixture 2 23 can be adjusted to adapt to the processing of linings 3 of different specifications. The servo motor 2 214 is started to reverse, so that the two lower fixtures 23 can be driven to push the two lower fixtures 1 22, so that the distance between the lower fixture 1 22 and the lower fixture 23 becomes smaller.

[0035] When in use, the upper forming group 1 is connected to the mechanical arm of the folding machine, and the cylinder is installed at the bottom of the lower forming group 2 to drive the lower forming group 2 to rise. When the lining 3 enters between the upper forming group 1 and the lower forming group 2, the servo motor 214 is started to drive the lower jig 22 and the lower jig 23 to adjust the spacing suitable for the lining 3, and then the cylinder is started to drive the lower forming group 2 to rise, so that the lower jig 22 and the lower jig 23 press the lining 3 to between the upper jig 12, the upper jig 13 and the upper jig 3 14, and at the same time, the servo motor 118 is started to shorten the distance between the upper jig 12, the upper jig 213 and the upper jig 3 14, and cooperate with the lower jig 22 and the lower jig 23 to clamp the lining 3, so as to bend out the protrusion 31 and the positioning portion 32 on the lining 3.

[0036] In summary, the lining folding box mechanism can automatically fold the lining 3 through the upper forming group 1 and the lower forming group 2. When used in conjunction with a folding box machine, it greatly improves the paper box processing efficiency and reduces manpower expenditure. The shape of the lining 3 after folding is also more standardized, which is in line with economic benefits and has broad application prospects.
