When the top edge of the bag can be heat sealed, the operator rotates the two-way screw 42 by the second crank 43 before the apparatus starts, the two sliders 41 move relatively to each other, the two heat seal plates 44 press the top plate of the bag, and the top edge of the bag is heat sealed by the two heat seal plates 44 when the apparatus starts.

The seal cutting mechanism 7 includes:

a drum conveyor 46 provided at the discharge end of the belt conveyor 13;

two sealing and cutting tools 47 are arranged, the two sealing and cutting tools 47 are both rotatably arranged on the roller conveyor 46, and the two sealing and cutting tools 47 are distributed up and down;

two straight-tooth gears 48 are arranged, one straight-tooth gear 48 is fixedly sleeved at one end of one sealing and cutting tool 47, the two straight-tooth gears 48 are mutually meshed, and one end of one sealing and cutting tool 47 is also connected with the output end of the roller conveyor 46 through a connecting belt 49.

When the articles are wrapped by the packaging bags and then are conveyed onto the roller conveyor 46, the roller conveyor 46 conveys the articles outwards, when the articles come between the two sealing and cutting tools 47, the roller conveyor 46 drives one sealing and cutting tool 47 to rotate, the two sealing and cutting tools 47 rotate relatively along with the rotation of the sealing and cutting tool through the meshing of the two straight-tooth gears 48, the two sealing and cutting tools 47 rotate together and then cut off one side of the packaging bags while packaging, and then the articles are packaged and finished.

The discharging mechanism 8 includes:

a rolling brush 50 rotatably disposed at a discharge end of the drum conveyor 46 in a horizontal state, the rolling brush 50 being driven by a transmission motor 51;

an output conveyor belt 52 arranged at the output end of the roller conveyor 46;

and the storage box 53 is arranged at the tail end of the discharging conveying belt 52.

When the packaging of the articles is completed, the roller brush 50 is driven by the transmission motor 51, the articles are taken out by the roller brush 50 to the discharging conveyor belt 52, and finally, the articles are transported to the storage box 53 for storage.

The working principle of the invention is as follows:

the device/apparatus/method realizes the functions of the invention by the following steps, thereby solving the technical problems proposed by the invention:

step one, in the automatic pillow type packaging process of the article, an operator places the unpacked articles in batches on the strip-shaped plate 9, the chain plate type conveyor 11 drives the articles to be pushed through the push rod 12, the articles are pushed towards the packaging feeding mechanism 2, and after the articles are pushed on the belt conveyor 13, the packaging bag is located on the belt conveyor 13 and is folded inwards through the two adjusting plates 15, so that the articles are wrapped in the packaging bag after coming on the packaging bag.

Step two, after the operator mounts the packaging bag on the winding roller 17, the operator winds one end of the packaging bag around the first tightening roller 19 and the second tightening roller 21 to play a role in preventing looseness, and then guides one end of the packaging belt to the sealing and cutting mechanism 7 through the operator, the packaging bag is limited by the first limiting disc 18, the second limiting disc 20 and the third limiting disc 22 to play a role in preventing shaking, when the folding degree of the packaging bag is adjusted, in order to enable the articles to be wrapped in the packaging bag, therefore, the driving motor 30 drives one driving gear 26 to rotate, the first driven gear 28 which is engaged with the driving gear rotates to drive the corresponding adjusting rod 25 to swing, the other driving gear 26 rotates along with the connection of the synchronous belt 27, the driving gear 26 drives the corresponding first driven gear 28 to rotate, the first driven gear 28 drives the second driven gear 29 to rotate, and the second driven gear 29 drives the corresponding adjusting rod 25 to swing, the two adjusting rods 25 swing relatively with each other, and each adjusting rod 25 swings relatively with each other to a proper position, so that the packaging bag can be conveyed in a pillow shape when bypassing the two adjusting rods 25.

Step three, when the top edges of the packaging bags are gathered inwards, an operator drives the threaded column 35 to rotate by shaking the first rocking plate, the threaded column 35 rotates to drive the movable plate 33 to move towards the fixed plate 32 through the contact 36, the two clamping wheels 38 limit the top edges of the packaging bags together, heat sealing of the top edges of the packaging bags is facilitated, when the top edges of the packaging bags can be subjected to heat sealing, the operator drives the two-way screw 42 to rotate through the second rocking handle 43 before the equipment is started, the two sliding blocks 41 move relatively along with the two rocking handle, the two heat sealing plates 44 press the top plates of the packaging bags into the two heat sealing plates 44, and when the equipment is started, heat sealing of the top edges of the packaging bags is completed through the two heat sealing plates 44.

Step four, after the articles are wrapped by the packaging bags and then are conveyed onto the roller conveyor 46, the roller conveyor 46 conveys the articles outwards, when the articles come between the two sealing and cutting tools 47, the roller conveyor 46 drives one sealing and cutting tool 47 to rotate, the two sealing and cutting tools 47 rotate relatively along with the two sealing and cutting tools through the meshing of the two straight-tooth gears 48, the two sealing and cutting tools 47 rotate together and then cut off one side of the packaging bags while packaging, the articles are packaged along with the articles, the roller brush 50 is driven by the transmission motor 51, the roller brush 50 takes the articles out of the discharging conveyor belt 52, and finally the articles are conveyed into the storage box 53 to be stored.
