[0033] The pipe delivery mechanism is arranged at the starting end of the fully automatic packaging device for stainless steel pipes, and is used to deliver pipes in rows at equal distances;

[0034] The film packaging assembly is arranged in the middle section of the stainless steel pipe automatic packaging device, and the film packaging assembly is used to cover a plurality of packaging bags in rows and at equal distances on a plurality of pipes; and

[0035] The bundling assembly is arranged at the rear end of the fully automatic packaging device for stainless steel pipes, and is used to embrace and bundle a plurality of pipes that are packaged with packaging bags by the film packaging assembly.

[0036] The film packaging assembly includes a bagging traction structure and two sets of heat sealing structures. The bagging traction structure includes a film covering member 16 horizontally slidably arranged above the frame 1. A top member 18 is horizontally fixed above the frame 1. The film covering member 16 is connected to the top member 18 through a drag chain 17. A row of film covering holes 27 for driving the bagging to package the tube are evenly arranged on the film covering member 16.

[0037] The heat sealing structure includes a correspondingly arranged pressing plate 20 and a hot melt plate 19, wherein the pressing plate 20 is vertically movably mounted on the frame 1 through a set of pushing cylinders 21, and the hot melt plate 19 is vertically movably mounted on the top component 18 through another set of pushing cylinders 21;

[0038] The tubes to be packaged are transported in rows to the film packaging assembly one by one by using the tube delivery mechanism. The bag traction structure in the film packaging assembly puts the packaging bag on each tube in the row. The heat sealing structure is used to heat-seal the port of the packaging bag. The bag is then transported to the bundling assembly, which wraps and bonds the rows of tubes.

[0039] In one embodiment of the present invention, the pipe delivery mechanism comprises a flow guide 3 fixed on the frame 1 and a roller 4 rotatably mounted on the frame 1;

[0040] The upper surface of the guide member 3 is in the shape of an oblique roller 4, and a plurality of fixed teeth 5 are arranged equidistantly around the circumference of the roller 4. A motor for driving the roller 4 to rotate intermittently is installed on one side of the roller 4;

[0041] When the motor drives the roller 4 to rotate intermittently, the fixed teeth 5 equidistantly arranged on the roller 4 are used to transport the pipe near the roller 4 to the sleeve packaging assembly. Since the guide member 3 is inclined, the pipe on the guide member 3 continuously approaches the roller 4 under the action of gravity.

[0042] In another embodiment of the present invention, an automatic tube arrangement assembly is further provided between the rotating roller 4 and the film packaging assembly, and the automatic tube arrangement assembly includes two conveying rollers 8 installed on the frame 1, and a conveying steel belt 9 rollingly provided on the two conveying rollers 8;

[0043] Among them, a section of the conveyor steel belt 9 is provided with continuous and equidistant separating teeth 10, one of the conveyor rollers 8 is provided near the rotating roller 4, and the other conveyor roller 8 is provided between the film packaging component and the strapping component, and a servo motor for driving the conveyor steel belt 9 to intermittently rotate forward and reverse is installed on one side of one of the conveyor rollers 8;

[0044] When the roller 4 is working, a section of the conveying steel belt 9 with the dividing teeth 10 is located close to the roller 4. When the roller 4 is working, the servo motor works at the same time, so that the pipes conveyed by the roller 4 through the fixed teeth 5 are arranged one by one between the dividing teeth 10, and the pipes arranged in rows between the dividing teeth 10 are transported to the sleeve packaging assembly.

[0045] In another embodiment of the present invention, a tilting member 6 for guiding the pipes separated from the fixed teeth 5 is fixed on the side of the guide member 3 close to the conveyor steel belt 9, and a blocking cylinder 7 for preventing subsequent pipes from sliding off the tilting member 6 after the pipes on the separation teeth 10 are fully arranged is arranged at the lower part of the tilting member 6;

[0046] The inclined member 6 guides the pipes detached from the fixed teeth 5 to fall accurately between two adjacent separating teeth 10 , and the blocking cylinder 7 works intermittently so that the number of pipes falling from the rotating roller 4 corresponds to the number of separating teeth 10 .

[0047] In another embodiment of the present invention, the film packaging assembly further includes a fixing assembly, the fixing assembly including a support 11 horizontally arranged above the frame 1 and a clamping member 12 correspondingly arranged above the support 11, the support 11 is movably mounted on the frame 1 through a set of fixed cylinders 13, and the clamping member 12 is movably mounted on the top member 18 through another set of fixed cylinders 13;

[0048] When the conveyor steel belt 9 uses a section with dividing teeth 10 thereon to transport the rows of pipes to between the support 11 and the clamping member 12, the servo motor stops working, and the two sets of fixed cylinders 13 at the upper and lower parts operate simultaneously, respectively driving the clamping member 12 to move downward and the support 11 to move upward, thereby lifting the rows of pipes out of the gap between the dividing teeth 10.

[0049] In another embodiment of the present invention, an insert 14 for inserting with a pipe is further provided between the hot melt plate 19 and the pressing plate 20. The insert 14 is in two groups, which are respectively provided on the front and rear sides of the device. A row of insert tubes for inserting with the end of the pipe is fixed on the insert 14. The insert 14 is connected to a vertical plate vertically fixed on the frame 1 through an insert cylinder 15. The insert tube on the front side is connected to a pump air component for inflating the packaging bag.

[0050] When the clamping member 12 moves downward and the supporting member 11 moves upward to lift and fix the pipe, the inserting cylinder 15 drives the inserting tube to be inserted with the fixed pipe end, and then the drag chain 17 drives the film sleeve member 16 to slide horizontally, and the packaging bag set at the film sleeve hole 27 is put on the pipe. When the film sleeve member 16 slides to a position close to the inserting member 14, the two groups of fixed cylinders 13 at the upper and lower parts are simultaneously reset, respectively driving the clamping member 12 to move upward and the supporting member 11 to move downward, so as to avoid the film sleeve member 16 from interfering with the clamping member 12 and the supporting member 11. At this time, the pipe is fixed by the inserting member 14; after the bagging is completed, the film sleeve member 16 returns, and the clamping member 12 and the supporting member 11 clamp the pipe covered with the packaging bag under the action of the fixed cylinder 13, and the inserting cylinder 15 reverses and drives the inserting tube to be separated from the fixed pipe end;

[0051] When the insertion tube is separated from the fixed pipe end, the two groups of pushing cylinders 21 at the upper and lower parts act simultaneously to drive the pressing plate 20 and the hot melt plate 19 to move up and down respectively, and the packaging bag extending out of the pipe end is hot-melt sealed. After the sealing is completed, the two groups of pushing cylinders 21 at the upper and lower parts act in the opposite direction at the same time to drive the pressing plate 20 and the hot melt plate 19 to move down and up respectively, so that the pressing plate 20 and the hot melt plate 19 are separated from the packaging bag, and the insertion cylinder 15 acts again to drive the insertion tube to be inserted into the fixed pipe end, so that the extended part of the packaging bag after hot-melt sealing is inserted into the pipe.

[0052] In another embodiment of the present invention, a row of bag opening clamping components for opening the bag opening of the packaging bag is further arranged inside the film hole 27, and the bag opening clamping components are coaxially corresponding to the film hole 27, and the bag opening clamping components include a fixed fitting 28 and a group of pneumatic clamping jaws 29;

[0053] The pneumatic clamp 29 cooperates with the fixed fitting 28 to open the bag opening and then insert it onto the pipe.

[0054] In another embodiment of the present invention, the strapping assembly includes a bracket 22 fixed on the base 2, the bracket 22 is in a 'Y' shape, pulleys 25 are rotatably mounted on the upper parts of both sides of the bracket 22, a rotating wheel 24 connected to a driving motor is rotatably mounted on the lower part of the bracket 22, a winding member 23 with a notch is rotatably arranged between the pulleys 25 and the rotating wheel 24 on both sides, and a sleeve shaft 26 for placing the tape is fixed on the side wall of the winding member 23;

[0055] When the inserting cylinder 15 is activated again to drive the inserting tube to be inserted with the fixed pipe end, so that the extended part of the packaging bag after hot-melt sealing is inserted into the pipe, the servo motor continues to work, and the conveying steel belt 9 drives the packaged pipe to fall onto the bracket 22, and then the servo motor works in the reverse direction to drive the conveying steel belt 9 to return to the roller 4;

[0056] When the packaged pipes fall onto the bracket 22, the driving motor drives the wheel 24 to rotate, and the rotating wheel 24 drives the winding member 23 to rotate under the action of the pulley 25, thereby driving the sleeve shaft 26 and the tape to make a circular motion, and the packaged pipes on the bracket 22 are bundled and wound and bonded.

[0057] In another embodiment of the present invention, a dumping assembly is provided below the bracket 22, the dumping assembly is swingably provided on the frame body 1, and a cutter for cooperating with the sleeve shaft 26 is provided below the bracket 22;

[0058] When the driving motor drives the winding member 23 to rotate a certain angle, the tape is wound around the bundled pipes. At this time, the tipping assembly flips and moves at an angle. During the flipping process, the cutter contacts the tape and cuts the tape. At the same time, the flipped tipping assembly separates the bundled bonded pipes from the bracket 22 and removes them from the frame 1, thereby achieving the effect of automatic unloading.
