[0002] The four-side sealing bag making machine is a device used to make packaging bags. It uses a specific mechanical structure and work flow to perform four-side sealing operations on materials such as paper bags. From feeding, conveying, folding to four-side sealing and molding, it can efficiently produce packaging bags with good sealing and regular appearance. The feeding device is a key part of the bag making machine. The feeding structure introduces the bag making materials and conveys the materials to the subsequent processing area smoothly and continuously, ensuring that the materials enter the edge sealing and other processes in an orderly manner, ensuring that the bag making process is carried out efficiently.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention drives the edge banding machine to move through the lifting cylinder, and drives the synchronous rod to slide in the hollow column. At this time, the upper edge banding machine can drive the lower edge banding machine to move synchronously through the synchronous rod, and perform four-side edge banding operations on the materials on the upper and lower conveyor belts at the same time; it greatly shortens the time required to produce the same number of bags, increases the output per unit time, and meets the needs of large-scale production. At the same time, it also ensures that the edge banding process of the upper and lower layers of materials is highly consistent. It avoids quality problems such as uneven edge banding and loose sealing due to asynchrony, and ensures the overall quality of the bag.

[0016] 2. The present invention sets an anti-skid device, and the pressure roller in the anti-skid device plays a pressing role. Under the restriction of the support plate, the compression spring applies a downward force to the mounting frame, and the mounting frame moves downward along the guide rod, so that the pressure roller presses on the material on the conveyor belt. When the material is transported on the conveyor belt, if there is a tendency to slip, the pressure roller will increase the pressure on the material under the elastic force of the compression spring, thereby increasing the friction force, effectively preventing the material from slipping, and ensuring that the material can be accurately and stably transported to the edge banding machine for processing.

[0017] 3. The present invention sets a feeding device, places the reel inside the rotating frame, and limits the reel by the locking assembly. When the device is not in use, the pressing assembly can be pushed by the pneumatic push rod to press the material on the reel to prevent it from loosening. In this way, when the device is not in use, the material wound on the outside of the reel can be prevented from being loosened. When the device is in use, the material passes through the side of the limiting frame close to the guide roller, so that it is wound on the surface of the guide roller, which can prevent the pressing assembly from interfering with the reel when the device is in use.

[0018] 4. The present invention pushes the sliding block to slide through the pneumatic push rod. At this time, the sliding block drives the assembly block and the arc-shaped pressure plate to approach the reel through the connecting rod. When the rubber roller outside the slider contacts the material on the reel, the pneumatic push rod stops working. At this time, the elastic plate outside the assembly plate produces elastic deformation. The elastic plate can adjust the thrust on the rubber roller in real time, so that the slider always pushes the rubber roller outward, thereby ensuring that the material is always tightly pressed on the reel. This adaptive clamping mechanism ensures that the material can maintain a stable clamping state under various working conditions, avoiding processing errors caused by loose materials.

[0019] 5. The present invention provides an assembly plate. When the assembly plate is removed from the surface of the assembly block, the elastic plate, the slider and the rubber roller can be directly pulled out from the assembly block. If the rubber roller is worn after long-term use, the compaction effect on the material will be affected. Through this detachable structure, it can be quickly taken out for replacement without disassembling the entire feeding device or other complex structures, which greatly shortens the maintenance time and improves the maintainability of the equipment.

[0020] 6. The present invention uses a pneumatic push rod to push the arc-shaped pressure plate to press the material on the roll, thereby limiting the rotation of the roll. By limiting the rotation of the roll, the material delivery and subsequent processing steps are synchronized, avoiding production pauses or production rhythm disorders caused by unstable material supply. This helps to improve the overall operating efficiency of the equipment and ensure the continuity and stability of the production process. At the same time, the output of the material is strictly matched with the processing rhythm of the bag making machine, avoiding unnecessary material loss and reducing production costs.

[0021] 7. The present invention provides a locking assembly so that the rotating block can rotate relative to the limiting block. The limiting of the reel can be completed through the joint action of the limiting block and the rotating frame. When the limiting component is separated from the limiting block, the limiting block automatically deflects under the gravity of the counterweight block, so that the axis of the reel can pass more smoothly from under the limiting block. When installing the reel, the operator can easily put the reel into the appropriate position, and when the reel needs to be disassembled for replacement or maintenance, it can also be quickly taken out.

[0022] 8. The present invention sets a limit component. Under the elastic force of the reset spring, the hollow slide rod pushes the block out of the fixed sleeve, thereby limiting the rotation of the limit block. The displacement of the block can be limited by inserting the flip card into the card slot, thereby preventing the block from accidentally moving due to external interference during operation.

[0023] 9. The present invention rotates the bolt so that the bolt pushes the L-shaped plate to rotate toward the flip card plate through the sliding rod. When the L-shaped plate is located above the flip card plate, the rotation of the flip card plate can be limited, further ensuring the stability of the card block position. This makes the working state of the entire limit component more stable and reliable.

[0024] 10. The present invention provides a limiting component. When it is necessary to release the restriction on the reel, the bolt is disengaged from the limiting cylinder by rotating the bolt in the opposite direction. Then, the hollow sliding rod can be pulled to the side away from the fixed sleeve by the bolt, the sliding rod and the L-shaped plate. At this time, the blocking block can be retracted into the fixed sleeve, thereby releasing the restriction on the reel, thereby enhancing the reliability of the entire limiting component and reducing production failures caused by unstable limiting.

During the conveying process, the pressure roller 54 of the anti-skid device 5 presses the material on the conveyor belt 6 to prevent slipping under the action of the compression spring 55. When the material moves on the conveyor belt 6, the lifting cylinder 2 drives the edge banding machine 3 to descend, so that the lifting cylinder 2 drives the edge banding machine 3 to move smoothly, and at the same time drives the synchronous rod 8 to slide in the hollow column 7. At this time, the upper edge banding machine 3 can drive the lower edge banding machine 3 to move synchronously through the synchronous rod 8, and perform four-side edge banding operations on the materials on the upper and lower conveyor belts 6 at the same time;

[0042] The feeding device 4 includes a rotating frame 41, the top of which is fixedly connected to a limiting frame 42, the inner side of the limiting frame 42 is rotatably connected to a guide roller 43, the inner side of the rotating frame 41 is movably mounted with a reel 44, the outer side of the rotating frame 41 is fixedly connected to a locking assembly 45, the inner side of the rotating frame 41 is fixedly connected to a pneumatic push rod 46, the output end of the pneumatic push rod 46 is fixedly connected to a clamping assembly 47, the reel 44 is placed on the inner side of the rotating frame 41, the reel 44 is limited by the locking assembly 45, when the device is not in use, the clamping assembly 47 can be pushed by the pneumatic push rod 46 to clamp the material on the reel 44 to prevent it from loosening. In this way, when the device is not in use, the material wound on the outer side of the reel 44 can be prevented from being loosened, and when the device is in use, the material is passed from the side of the limiting frame 42 close to the guide roller 43, so that it is wound on the surface of the guide roller 43, which can prevent the clamping assembly 47 from interfering with the reel 44 when the device is in use;

[0043] The locking assembly 45 includes a limit block 451, the outer side of the limit block 451 is rotatably connected to a rotating block 452, the outer side of the limit block 451 is fixedly connected to a counterweight block 454, a limit component 453 is arranged on the outer side of the limit block 451, the bottom of the limit component 453 is fixedly connected to the top of the rotating frame 41, the outer side of the rotating frame 41 is rotatably connected to the outer side of the conveying frame 1, the side of the rotating frame 41 away from the conveying frame 1 is rotatably connected to the bottom end of the telescopic cylinder 9, the two sides of the clamping assembly 47 are slidably connected to the inner side of the rotating frame 41, the outer side of the rotating block 452 is connected to the outer side of the rotating frame 41 The rotating block 452 is fixedly connected to the side, and the rotating block 452 can rotate relative to the limit block 451. The limit of the reel 44 can be completed through the joint action of the limit block 451 and the rotating frame 41. When the limit component 453 is separated from the limit block 451, the limit block 451 is automatically deflected under the gravity of the counterweight block 454, so that the axis of the reel 44 can pass more smoothly from under the limit block 451. When installing the reel 44, the operator can easily put the reel 44 into a suitable position, and when the reel 44 needs to be disassembled for replacement or maintenance, it can also be quickly taken out.

[0044] The anti-skid device 5 includes a support plate 51, a guide rod 52 is fixedly connected to the bottom of the support plate 51, a mounting frame 53 is slidably connected to the outer wall of the guide rod 52, a pressure roller 54 is rotatably connected to the bottom of the mounting frame 53, a compression spring 55 is fixedly connected to the top of the mounting frame 53, both sides of the support plate 51 are fixedly connected to the outer side of the conveying frame 1, the bottom of the support plate 51 is fixedly connected to the top of the compression spring 55, and the pressure roller 54 is located at the top of the conveyor belt 6. The pressure roller 54 in the anti-skid device 5 plays a pressing role. Under the restriction of the support plate 51, the compression spring 55 applies a downward force to the mounting frame 53, and the mounting frame 53 moves downward along the guide rod 52, so that the pressure roller 54 presses on the material on the conveyor belt 6. When the material is transported on the conveyor belt 6, if there is a tendency to slip, the pressure roller 54 will increase the pressure on the material under the elastic force of the compression spring 55, thereby increasing the friction, effectively preventing the material from slipping, and ensuring that the material can be accurately and stably transported to the edge banding machine 3 for processing.

[0045] The limiting component 453 includes a fixing sleeve 531, the inner wall of the fixing sleeve 531 is slidably connected with a clamping block 532, the outer side of the clamping block 532 is fixedly connected with a hollow sliding rod 533, the outer side of the hollow sliding rod 533 is fixedly connected with a return spring 534, the end of the return spring 534 away from the hollow sliding rod 533 is fixedly connected to the limiting cylinder 535, the bottom of the fixing sleeve 531 is fixedly connected to the top of the rotating frame 41, the outer wall of the fixing sleeve 531 is rotatably connected with a flip clamping plate 536, the outer wall of the hollow sliding rod 533 is slidably connected to the inner wall of the limiting cylinder 535, the inner wall of the limiting cylinder 535 is threadedly connected with a bolt 537, the center of the bolt 537 is rotatably connected with a sliding rod 538, the top of the sliding rod 538 is fixedly connected with an L-shaped plate 539, the bottom of the L-shaped plate 539 is slidably connected to the inner wall of the hollow sliding rod 533, the inner wall of the hollow sliding rod 533 is rotatably connected to the outer wall of the sliding rod 538 The wall is slidably connected, and the outer wall of the flip card plate 536 is clamped with the inner wall of the block 532 through the clamping groove 530, and the clamping groove 530 is opened in the wall of the block 532. When the limiting component 453 is in use, under the elastic force of the return spring 534, the hollow sliding rod 533 pushes the block 532 out of the fixing sleeve 531, thereby limiting the rotation of the limiting block 451 through the block 532, wherein the displacement of the block 532 can be limited by clamping the flip card plate 536 into the clamping groove 530, thereby preventing the block 532 from accidentally moving due to external interference during operation; then, the bolt 537 is rotated so that the bolt 537 pushes the L-shaped plate 539 to rotate toward the flip card plate 536 through the sliding rod 538. When the L-shaped plate 539 is located above the flip card plate 536, the rotation of the flip card plate 536 can be limited, further ensuring the stability of the position of the block 532. This makes the working state of the entire limiting component 453 more stable and reliable; when it is necessary to release the restriction on the reel 44, the bolt 537 is disengaged from the limiting cylinder 535 by rotating the bolt 537 in the opposite direction, and then the hollow sliding rod 533 can be pulled to the side away from the fixed sleeve 531 through the bolt 537, the sliding rod 538 and the L-shaped plate 539. At this time, the block 532 can be retracted into the fixed sleeve 531, thereby releasing the restriction on the reel 44, thereby enhancing the working reliability of the entire limiting component 453 and reducing production failures caused by unstable limiting.

[0046] The clamping assembly 47 includes a sliding block 471, the outer side of the sliding block 471 is fixedly connected to a connecting rod 478, the outer wall of the connecting rod 478 is fixedly connected to an assembly block 472, the outer side of the assembly block 472 is fixedly connected to an arc-shaped pressing plate 473, the outer wall of the sliding block 471 is slidably connected to the inner wall of the rotating frame 41, the outer wall of the assembly block 472 is fixedly connected to an assembly plate 477, the outer side of the assembly plate 477 is fixedly connected to an elastic plate 476, the outer side of the elastic plate 476 is fixedly connected to a slider 474, the outer side of the slider 474 is rotatably connected to a rubber roller 475, the outer wall of the slider 474 is connected to the inner wall of the assembly block 472 The inner wall is slidably connected. During normal use of the device, the pneumatic push rod 46 pushes the sliding block 471 to slide. At this time, the sliding block 471 drives the assembly block 472 and the arc pressure plate 473 to approach the reel 44 through the connecting rod 478. When the rubber roller 475 on the outside of the slider 474 contacts the material on the reel 44, the pneumatic push rod 46 stops working. At this time, the elastic plate 476 on the outside of the assembly plate 477 produces elastic deformation. The elastic plate 476 can adjust the thrust on the rubber roller 475 in real time, so that the slider 474 always pushes the rubber roller 475 outward, thereby ensuring that the material is always tightly pressed on the reel 44. This adaptive clamping mechanism ensures that the material can maintain a stable clamping state under various working conditions, avoiding processing errors caused by loose materials; wherein the assembly plate 477 is fixedly connected to the assembly block 472 through a nut, and when the assembly plate 477 is removed from the surface of the assembly block 472, the elastic plate 476, the slider 474 and the rubber roller 475 can be directly pulled out from the assembly block 472. If the rubber roller 475 is worn after long-term use, the clamping effect on the material is affected. Through this detachable structure, it can be quickly taken out for replacement without disassembling the entire feeding device 4 or other complex structures, which greatly shortens the maintenance time and improves the maintainability of the equipment; when the pneumatic push rod 46 pushes the arc-shaped pressure plate 473 to clamp the material on the reel 44, the rotation of the reel 44 is restricted. By restricting the rotation of the reel 44, the material conveying and subsequent processing procedures (such as conveying, edge sealing, etc.) are synchronized, avoiding production pauses or production rhythm disorders caused by unstable material supply. This helps to improve the overall operating efficiency of the equipment and ensure the continuity and stability of the production process. At the same time, it makes the output of materials strictly match the processing rhythm of the bag making machine, avoiding unnecessary material loss and reducing production costs.

[0047] Working principle:

[0048] First, the conveyor frame 1 is moved to the designated position, and then the feeding device 4 is used to feed the material. The material enters the conveyor belt 6 after being guided. The telescopic cylinder 9 can adjust the deflection angle of the feeding device 4. During the conveying process, the pressure roller 54 of the anti-skid device 5 presses the material of the conveyor belt 6 to prevent slipping under the action of the compression spring 55. When the material moves on the conveyor belt 6, the lifting cylinder 2 drives the edge banding machine 3 to descend, so that the lifting cylinder 2 drives the edge banding machine 3 to move smoothly, and at the same time drives the synchronous rod 8 to slide in the hollow column 7. At this time, the upper edge banding machine 3 can drive the lower edge banding machine 3 to move synchronously through the synchronous rod 8, and perform four-side edge banding operations on the materials on the upper and lower conveyor belts 6 at the same time; the time required to produce the same number of bags is greatly shortened, the output per unit time is increased, and the needs of large-scale production are met. At the same time, it also ensures that the edge banding process of the upper and lower layers of materials is highly consistent. It avoids quality problems such as uneven edge banding and loose sealing due to asynchronism, and ensures the overall quality of the bag.

[0049] The pressure roller 54 in the anti-skid device 5 plays a pressing role. Under the restriction of the support plate 51, the compression spring 55 applies a downward force to the mounting frame 53, and the mounting frame 53 moves downward along the guide rod 52, so that the pressure roller 54 presses on the material on the conveyor belt 6. When the material is conveyed on the conveyor belt 6, if there is a tendency to slip, the pressure roller 54 will increase the pressure on the material under the elastic force of the compression spring 55, thereby increasing the friction force, effectively preventing the material from slipping, and ensuring that the material can be accurately and stably conveyed to the edge banding machine 3 for processing.

[0050] When the feeding device 4 is in use, first, the reel 44 is placed inside the rotating frame 41, and the reel 44 is limited by the locking assembly 45. When the device is not in use, the pressing assembly 47 can be pushed by the pneumatic push rod 46 to press the material on the reel 44 to prevent it from loosening. In this way, when the device is not in use, the material wound on the outside of the reel 44 can be prevented from being loosened. When the device is in use, the material passes through the side of the limiting frame 42 close to the guide roller 43, so that it is wound on the surface of the guide roller 43, which can prevent the pressing assembly 47 from interfering with the reel 44 when the device is in use.

[0051] During normal use of the device, the pneumatic push rod 46 pushes the sliding block 471 to slide. At this time, the sliding block 471 drives the assembly block 472 and the arc-shaped pressure plate 473 to approach the reel 44 through the connecting rod 478. When the rubber roller 475 on the outside of the slider 474 contacts the material on the reel 44, the pneumatic push rod 46 stops working. At this time, the elastic plate 476 on the outside of the assembly plate 477 produces elastic deformation. The elastic plate 476 can adjust the thrust on the rubber roller 475 in real time, so that the slider 474 always pushes the rubber roller 475 outward, thereby ensuring that the material is always tightly pressed on the reel 44. This adaptive clamping mechanism ensures that the material can maintain a stable clamping state under various working conditions, avoiding processing errors caused by loose materials.

[0052] The assembly plate 477 is fixedly connected to the assembly block 472 through a nut. When the assembly plate 477 is removed from the surface of the assembly block 472, the elastic plate 476, the slider 474 and the rubber roller 475 can be directly pulled out from the assembly block 472. If the rubber roller 475 is worn after long-term use, the compaction effect on the material will be affected. With this detachable structure, it can be quickly taken out for replacement without disassembling the entire feeding device 4 or other complex structures, which greatly shortens the maintenance time and improves the maintainability of the equipment.

[0053] When the pneumatic push rod 46 pushes the arc-shaped pressing plate 473 to press the material on the reel 44, the rotation of the reel 44 is restricted. By restricting the rotation of the reel 44, the material conveying and subsequent processing procedures (such as conveying, edge sealing, etc.) are synchronized, avoiding production pauses or production rhythm disorders caused by unstable material supply. This helps to improve the overall operating efficiency of the equipment and ensure the continuity and stability of the production process. At the same time, the output of the material is strictly matched with the processing rhythm of the bag making machine, avoiding unnecessary material loss and reducing production costs.

[0054] When the locking assembly 45 is in use, the rotating block 452 can rotate relative to the limit block 451, and the limit of the reel 44 can be completed through the joint action of the limit block 451 and the rotating frame 41. When the limit component 453 is disengaged from the limit block 451, the limit block 451 automatically deflects under the gravity of the counterweight block 454, so that the axis of the reel 44 can pass more smoothly from under the limit block 451. When installing the reel 44, the operator can easily put the reel 44 into the appropriate position, and when the reel 44 needs to be disassembled for replacement or maintenance, it can also be quickly taken out.

[0055] When the limiting component 453 is in use, under the elastic force of the return spring 534, the hollow slide rod 533 pushes the block 532 out of the fixed sleeve 531, thereby limiting the rotation of the limiting block 451 through the block 532, wherein the displacement of the block 532 can be limited by inserting the flip card plate 536 into the card slot 530, thereby preventing the block 532 from accidentally moving due to external interference during operation.

[0056] Then, the bolt 537 is rotated so that the bolt 537 pushes the L-shaped plate 539 to rotate toward the flip card plate 536 through the sliding rod 538. When the L-shaped plate 539 is located above the flip card plate 536, the rotation of the flip card plate 536 can be limited, further ensuring the stability of the position of the clamping block 532. This makes the working state of the entire limiting component 453 more stable and reliable;

[0057] When it is necessary to release the restriction on the reel 44, the bolt 537 is rotated in the opposite direction to disengage the bolt 537 from the limiting cylinder 535, and then the hollow sliding rod 533 can be pulled to the side away from the fixed sleeve 531 through the bolt 537, the sliding rod 538 and the L-shaped plate 539. At this time, the block 532 can be retracted into the fixed sleeve 531, thereby releasing the restriction on the reel 44, thereby enhancing the reliability of the entire limiting component 453 and reducing production failures caused by unstable limiting.
