The principle and specific structure of the present embodiment are further detailed below:

as shown in fig. 12, the mattress 1 'is subjected to a wrapping and packaging process in a wrapping machine to form a compressed mattress 2', a wrapped mattress 3 ', and a packaged mattress 4', respectively.

First, the mattress is compressed and transported by the input assembly 1 of the wrapping machine. Referring to fig. 3, the upper input assembly 11 is hinged above the lower input assembly 12 and is connected with an opening and closing cylinder 13; the upper input assembly 11 and the lower input assembly 12 are both arranged on an input bracket 14, and the input bracket 14 can move back and forth; the upper input assembly 11 and the lower input assembly 12 are each provided with a conveyor belt 15. Specifically, the input fixing frame 16 is provided with a feeding motor 17, a screw rod 18, a feeding guide rod 19 and a movable beam 10; one end of the screw rod 18 is connected with the movable beam 10, and the other end of the screw rod is connected with the feeding motor 17; the feeding motor 17 can drive the screw rod 18 to rotate, so as to drive the movable beam 10 to be far away from or close to the input fixed frame 16; the movable beam 10 is provided with the input support 14, and the movable beam 10 drives the input support 14 to drive the upper input assembly 11 and the lower input assembly 12 to horizontally move.

When the mattress is fed to the feeding end of the upper input assembly 11 and the lower input assembly 12, the opening and closing cylinder 13 drives the upper input assembly 11 to turn downwards, and then the conveyer belts 15 on the upper input assembly 11 and the lower input assembly 12 drive the mattress to move, and the mattress is gradually compressed. When the mattress reaches the discharge end of the upper input assembly 11 and the lower input assembly 12, the upper input assembly 11 and the lower input assembly 12 move horizontally, feeding the compressed mattress into the wrapping assembly 2. Through setting up input support 14 that can remove, can directly send the entrance of mattress wraparound die cavity 24 with the mattress that the compression is good, place the mattress and take place to kick-back before the wraparound, influence the wraparound compactness.

Then, the wrapping unit 2 starts to operate to wrap the mattress. Referring to fig. 5 to 7, the turntable driving mechanism 21 includes a turntable motor 211, a transmission gear 212, a sliding plate 213, and a first linear guide 214; the sliding plate 213 is disposed on the first linear guide 214; a rack 215 is fixedly arranged on the sliding plate 213, and the transmission gear 212 is meshed with the rack 215; the sliding plate 213 is provided with a driving block 216.

The frame 6 is further provided with a fourth slot 62, and the electric roller connecting block 231 is disposed in the fourth slot 62 and can slide along the fourth slot 62.

In the initial state, the motorized roller assemblies 23 are in a state of being far away from each other, and the space of the mattress wrapping forming cavity 24 is large. When the rolling is started, the turntable motor 211 drives the sliding plate 213 to move through the transmission gear 212, and the sliding plate 213 translates to drive the turntable 22 to rotate; since the motorized roller connection block 231 is restricted by the fourth slot 62 and can only slide in the direction of the fourth slot 62, when the rotary plate 22 rotates, the motorized roller assembly 23 is driven to move toward the mattress wrapping cavity 24 through the third slot 223 thereof, so that the mattress wrapping cavity 24 is contracted to the minimum diameter. At the moment, the input assembly 1 sends the mattress into the mattress wrapping forming cavity 24, and the electric roller 232 is internally provided with a motor and can actively rotate; the feed force of the mattress is provided by the rotation of motorized pulley 232. In the wrapping process, the turntable motor 211 drives the sliding plate 213 to move through the transmission gear 212, and the sliding plate 213 translates to drive the turntable 22 to rotate, so that the mattress wrapping forming cavity 24 becomes larger according to the gradually larger diameter of the mattress. Through set up third slotted hole 223 on carousel 22, the different positions of third slotted hole 223 are different from the distance of carousel rotation center for all electric drum subassembly 23 can follow the rotation of carousel 22 and be close to or keep away from the rotation center in step, have guaranteed the uniformity of the package centre of a circle of rolling up, and the atress is even when making its package of rolling up, improves the package quality of rolling up. On the other hand, through the transmission design of the turntable motor 211, the transmission gear 212 and the sliding plate 213 to the turntable 22, the whole relative displacement of the motorized pulley 232 can be accurately controlled under the condition that the motorized pulley is subjected to large pressure, so that the mattress is rolled compactly, and wrinkles cannot be generated due to over-tight rolling.

Referring to fig. 8, when the wrapping is about to be completed, the wrapping film is fed to the wrapping mechanism, and after the wrapping mechanism continues to rotate the mattress for several turns, the cutter 31 of the film cutting unit 3 moves to cut the wrapping film at the film cutting unit 3. After the packaging film is cut, the welding assembly 4 welds the packaging film.

Referring to fig. 9, the welding assembly 4 includes a welding driving cylinder 41, a guide rod 42, a fixed beam 43, a welding rectangular tube 44, and a heating plate 45; the fixed beam 43 is provided with a guide sleeve 46, the welding rectangular tube 44 is provided with a guide rod 42, and the guide rod 42 is sleeved in the guide sleeve 46; the heating sheet 45 is arranged below the welding rectangular tube 44; the welding driving cylinder 41 can drive the welding torque tube 44 to move up and down relative to the fixed beam 43.
