Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, and particularly relates to a large-bag automatic wire shearing and extracting machine. Background Art

[0002] In the industrial production and transportation processes, many stacks are bundled with iron wires. For example, after the pulp stockboard is produced, it is usually packaged into a small pulp bag, and the small pulp bag is bundled with 4 iron wires in a # shape. Then, a special large-bag bundling machine is used to bundle 6 - 8 rectangular or square small pulp bags into a large pulp bag stack. Specifically, two pulp bags are placed back to back and close to each other, and then 3 - 4 layers of the same pulp bags are stacked on top. To keep the pulp bag stack as a whole, 7 - 8 turns of iron wires are used to bundle all the small pulp bags within a symmetric plane of the pulp bag stack. There are usually 7 - 8 iron wires on a pulp board stack, and the maximum diameter of the iron wire reaches 3.5 mm. Before the pulp bag stack enters the pulper, the bundling iron wires on it must be removed first.

[0003] For the patent "201020664432.X" named "Automatic Wire Shearing and Extracting Machine", it shears the iron wire above the pulp bag and winds and extracts the iron wire on the side of the pulp bag.

The driving unit is used to drive the grabbing knife assembly 65 to approach the wire and can drive the grabbing knife assembly 65 to grab the wire.

[0038] Please refer to Figure 7 , the wire winding mechanism 7 includes a fixed frame 71, a fork rod 74 slidably connected to the lower part of the fixed frame 71 through a movable frame 73 and a linear guide rail, a second oil cylinder 72 fixedly installed under the fixed frame 71 for driving the movable frame 73 to move, a driving component 75 installed on the movable frame 73 and moving with the movable frame 73 for driving the fork rod 74 to rotate, and a compressing unit for compressing the wire wound on the fork rod 74.

[0040] Please refer to Figure 1 and Figure 2 , a collecting hopper 9 for collecting waste wire is installed on one side of the machine frame 1 corresponding to the wire winding mechanism 7 after transverse movement.

[0041] Please refer to Figure 1 and Figure 7 , the pressing mechanism includes a lifting oil cylinder 2, a lifting frame 3 and a pressing package square pipe 10 installed on the wire winding mechanism 7.

[0042] Please refer to Figure 5 , the jacking mechanism includes a jacking oil cylinder 55. The top of the jacking oil cylinder 55 is installed with a jacking frame 56, and the jacking frame 56 is fixedly connected to the scissors seat 52.

[0043] When using the present invention:

[0044] The large pulp bale stack is conveyed into the interior of the machine frame 1 through the conveying mechanism 4 and is located directly above the shearing assembly 5;

[0045] Then the lifting oil cylinder 2 in the dislocation assembly will make the lifting frame 3 move up and down along the linear guide rail on the machine frame 1, so that the lifting frame 3 carries the wire winding mechanism 7 and the wire grabbing mechanism 6 to descend, and the pressing package square pipe 10 installed on the wire winding mechanism 7 descends to press a part of the large pulp bale stack;

[0046] Then the jacking oil cylinder 55 in the jacking mechanism installed on the shearing assembly 5 carries the jacking frame 56 to lift another part of the large pulp bale stack, so as to create a gap between the wire at the bottom of the stack and the pulp bale stack itself through the dislocation of the large pulp bale stack;

[0047] Moreover, the jacking frame 56 is fixedly connected to the scissors seat 52. That is, when the jacking oil cylinder 55 in the dislocation assembly rises, it can carry the shearing unit 54 through the scissors seat 52 to approach the iron wire that forms a gap with the large pulp bale stack, and make the iron wire located in the scissors blades 543 in the shearing unit 54. Then, the scissors oil cylinder 541 drives the scissors blades 543 to move in the limit support 542 to realize the shearing of the iron wire.

[0048] While the shearing assembly 5 shears the iron wire, it is necessary to activate the iron wire grabbing mechanism 6 located on the lifting frame 3. When the iron wire grabbing mechanism 6 is activated, it will make the grabbing knife assembly 65 approach the iron wire and grab it through the driving unit.

[0049] Then, the second oil cylinder 72 in the iron wire winding mechanism 7 will drive the movable frame 73 to carry the fork rod 74 to fork the iron wire. Then, the driving component 75 will make the fork rod 74 rotate to wind the iron wire. Then, the compression unit will compress the wound iron wire. Finally, the iron wire winding mechanism 7 carrying the iron wire will move out of the range of the machine frame 1 under the drive of the transverse movement oil cylinder 8, that is, the compressed iron wire can fall into the collection hopper 9.

[0050] When the iron wire is processed, the jacking oil cylinder 55 in the dislocation assembly makes the protruding part of the large pulp bale stack descend onto the transmission mechanism 4 and be transported away by the transmission mechanism 4.

[0051] That is, the device can cut the iron wire under the large pulp bale stack and roll up the iron wire on the upper surface of the pulp bale, so that the feeding and discharging directions of the large pulp bale stack are the same, thus saving the layout space of the workshop.

[0052] The iron wire winding mechanism 7 in the present invention specifically includes a fixed frame 71, a fork rod 74, a second oil cylinder 72, a driving component 75 and a compression assembly; the fork rod 74 is slidably connected to the lower part of the fixed frame 71 through the movable frame 73 and a linear guide rail; the second oil cylinder 72 is fixedly installed under the fixed frame 71 and is used to drive the movable frame 73 to carry the fork rod 74 to move towards the iron wire on the linear guide rail under the fixed frame 71; the driving component 75 is installed on the movable frame 73 and moves with the movable frame 73, and is used to make the fork rod 74 rotate to wind the iron wire; the compression assembly is installed at the bottom of the fixed frame 71 and is used to compress the iron wire wound on the fork rod 74.

[0053] The compression assembly includes a fixed support 76, a movable support 77 and a first oil cylinder 79 for moving the movable support 77; the fixed support 76 is installed in the middle of the fixed frame 71, the movable support 77 is slidably connected to the fixed frame 71 through a linear guide rail, and a working position for iron wire compression is formed between the fixed support 76 and the movable support 77; the first oil cylinder 79 is installed on the fixed frame 71 through an ear seat.

[0054] Both the fixed support 76 and the movable support 77 are provided with a through hole 78 for the fork rod 74 to pass through, so that the fork rod 74 can enter the work station to fork the iron wire without affecting the compression of the iron wire by the movable support 77.

[0055] A barrier rod 710 for limiting the diameter of the wire roll is provided between the fixed support 76 and the movable support 77 . One end of the barrier rod 710 is fixedly mounted on the fixed support 76 , and the other end movably passes through the movable support 77 .

[0056] The fork rod 74 is mounted on the movable frame 73 via a bearing. The driving component 75 includes a motor 753 mounted on the movable frame 73 via a motor base 754, a driving sprocket 755 mounted on the output shaft of the motor 753, and a driven sprocket 751 mounted on the fork rod 74. The driving sprocket 755 and the driven sprocket 751 are connected to each other via a driving chain 752.

[0057] When using the wire winding mechanism 7: first, the second oil cylinder 72 needs to be activated to drive the movable frame 73 carrying the fork rod 74 to move toward the wire on the linear guide rail below the fixed frame 71. The fork rod 74 will pass through the through hole 78 on the fixed support 76 and move toward the through hole 78 on the movable support 77. That is, the fork rod 74 can fork the wire at the working position;

[0058] Then the motor 753 in the driving component 75 on the movable frame 73 is started, that is, the driving sprocket 755 drives the driven sprocket 751 to rotate through the driving chain 752. The rotation of the driven sprocket 751 causes the fork rod 74 to rotate with the wire and reel it onto the surface of the fork rod 74. Due to the setting of the blocking rod 710, the range formed by the wire when the fork rod 74 rotates within the blocking rod 710 is limited, that is, the volume of the reeled wire can be preliminarily limited.

[0059] When the winding is completed, the first oil cylinder 79 in the compression assembly will drive the movable support 77 to move toward the fixed support 76, that is, it can squeeze the rolled wire on the fork rod 74, thereby further reducing the volume occupied by the wire, making it easier to store the wire later.

[0060] In the wire grasping mechanism 6 of the present invention, it specifically includes: a mounting frame 61, a knife grasping component 65, and a driving unit. A connecting frame 63 is vertically installed on one side of the mounting frame 61 through a linear guide rail; the knife grasping component 65 is installed on the connecting frame 63. The knife grasping component 65 includes a knife grasping frame 651. A first clamping blade 652 is fixedly installed in the knife grasping frame 651, and a second clamping blade 653 is movably installed. The relative movement of the second clamping blade 653 towards the first clamping blade 652 can clamp the wire located between the first clamping blade 652 and the second clamping blade 653; the driving unit includes a first push rod 62 installed on the connecting frame 63 for driving the second clamping blade 653 to move within the knife grasping frame 651, and a second push rod 64 perpendicular to the first push rod 62. The second push rod 64 is installed on the knife grasping frame 651 of the knife grasping component 65 through a connecting seat and is used to drive the entire knife grasping component 65 and the connecting frame 63 to move.

[0061] The knife grasping frame 651 is a U-shaped frame. The bottoms of the first clamping blade 652 and the second clamping blade 653 respectively protrude to form a first grasping ear 6521 and a second grasping ear 6531. Both the first grasping ear 6521 and the second grasping ear 6531 are arc-shaped and curved, and the bending arcs of the first grasping ear 6521 and the second grasping ear 6531 are symmetrical to each other.

[0062] The number of the second clamping blades 653 is one, and the top is slidably connected to the center of the inner wall of the knife grasping frame 651. The number of the first clamping blades 652 is two. The two first clamping blades 652 are installed on both sides of the second clamping blade 653 and are fixedly connected to both sides of the knife grasping frame 651 through bolts;

[0063] When using the wire grasping mechanism 6, first, the device needs to be moved towards the wire by the first push rod 62 carrying the knife grasping component 65. Since a plurality of first grasping ears 6521 and a plurality of second grasping ears 6531 are respectively provided on the first clamping blade 652 and the second clamping blade 653 in the knife grasping component 65, that is, each wire can be respectively located between two staggered first grasping ears 6521 and second grasping ears 6531. Then, the second push rod 64 is started. The start of the second push rod 62 will cause the second clamping blade 653 to move relative to the first clamping blade 652, that is, it can clamp the wire located between the first grasping ear 6521 and the second grasping ear 6531. And due to the setting of the first push rod 64, the knife grasping component 65 can also move after clamping the wire.

[0064] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
