Automatic wrapping machine

Abstract

The present application relates to the technical field of roll packaging, in particular to an automatic roll packaging machine. The technical scheme comprises: an auxiliary protection box, a packaging bag transmission frame fixedly installed at one end of the auxiliary protection box, a transmission assembly slidingly installed at one end of the packaging bag transmission frame, and a packaging bag fixedly installed at one end of the transmission assembly through a plastic bag arrangement assembly. The application further comprises: a winding frame slidingly installed inside the auxiliary protection box. Through air pressure, the main support plate drives the electric telescopic assembly to be stored inside the hollow guide tube, causing the four plastic bag center positioning rods to gradually seal the packaging bag while pressing it down. Before closing, the airflow between the roll and the packaging bag is released, and the airflow is squeezed out from the inside of the packaging bag, so that the air in the plastic bag is squeezed out. This facilitates rope banding and avoids the situation of bag explosion due to excessive airflow in the bag during banding.

Description

Technical Field

[0001] This invention relates to the field of fabric packaging technology, and more particularly to an automatic fabric packaging machine. Background Technology

[0002] Automatic fabric roll packaging machines pull fabric rolls from an initial position (usually a roller or reel) in preparation for packaging. The rolls are positioned and aligned to ensure accuracy during packaging. The rolls are packaged according to preset requirements, typically using automated methods to ensure efficiency and quality. Once packaging is complete, the machine seals and cuts the rolls into individual packaging units. However, during this process, bagging components directly wrap the rolls. Because the bags contain a lot of air during the installation process, direct bagging leaves air trapped inside. Furthermore, the bags are taut due to the airflow, making them prone to bursting during transport if the wrapped rolls collide with other objects, resulting in packaging failure.

[0003] The publicly available patent document CN216735043U discloses an inner bag tying machine, which includes inner rods and outer rods. Several clamping devices are provided at the lower part of the outer rods. The inner and outer rods are arranged in pairs, and there are several of them. The inner rods are driven by an opening and closing mechanism, and the outer rods are driven by a driving device. The inner bag tying machine also includes a tying device, which includes a binding rope clamping mechanism and a binding rope tightening mechanism. This enables the automatic straightening, gathering, and tying of the inner bag, making it a key component of automated packaging lines for inner bag tying and outer bag sewing, and a pre-process for subsequent outer bag sewing.

[0004] The above devices have the following problems when in use:

[0005] The rope-tying machine has a fixed rope-tying position for plastic bags and rolls of cloth of different lengths. However, for rolls of cloth that are longer and occupy a larger proportion of the plastic bag, the rope-tying components are prone to clamping the roll of cloth when they are being attached and gripped. This can damage the appearance of the roll of cloth and result in the plastic straps not being tied properly, leading to a loose tie.

[0006] Therefore, this application proposes an automatic cloth packaging machine. Summary of the Invention

[0007] The purpose of this invention is to address the problem in the prior art that the rope-tying machine has a fixed rope-tying position for plastic bags and rolls of cloth of different lengths. However, for rolls of cloth that are longer and occupy a larger proportion of the plastic bag, the rope-tying components are prone to clamping the roll of cloth during the bonding and gripping process, resulting in damage to the appearance of the roll of cloth and incomplete or loose rope tying of the plastic strip.

[0019] Optionally, the outer surface of the auxiliary protective box is fixedly connected to the main support platform of the packaging machine, and the main support platform of the packaging machine is rotatably connected to the inside of the main support platform.

[0020] Optionally, a positioning protective frame is fixedly connected to the outer surface of the main support platform of the packaging machine, and an auxiliary positioning plate is slidably connected to the inner wall of the positioning protective frame.

[0021] Optionally, the bottom end of the auxiliary positioning plate is fixedly connected to two sets of buffer springs, and the bottom ends of the two sets of buffer springs are fixedly connected to an adhesive rod for installing labels.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] 1. The four sets of plastic bag center positioning rods are pushed towards the center by the air pressure pushing mechanism on the surface of the main support plate, causing the four sets of plastic bag center positioning rods to adhere to the outer surface of the packaging bag. As the opening of the packaging bag on the side used to store the rolled cloth is squeezed by the plastic bag center positioning rods, it gradually closes and seals. At the same time, as the air pressure drives the electric telescopic component through the main support plate to retract into the hollow guide tube, the four sets of plastic bag center positioning rods gradually seal the packaging bag while pressing down on the packaging bag. Before sealing, the airflow between the rolled cloth and the packaging bag is released, and the airflow is squeezed out from the inside of the packaging bag, thereby squeezing out the air in the plastic bag. This makes it easier to tie with rope and avoids the bag bursting due to excessive airflow in the bag during tying.

[0024] 2. After the packaging bag is sealed by the four sets of plastic bag center positioning rods, as the turntable drives the gear plate to rotate via the conveyor belt, the gear plate drives the rope to rotate along the outer surface of the packaging bag via the rope rotation component. At the same time, the angle adjustment component drives the rope clamping component to bend and rotate the packaging bag to bind it through air pressure. The deflection and recovery of the packaging bag completes the knotting action of the rope, similar to a double fish knot, thereby quickly completing the packaging of the roll of cloth, replacing manual binding, and the binding is tighter.

[0025] 3. The limiting hole at one end of the multi-position positioning rod squeezes the pressure sensor. The pressure sensor transmits an electrical signal through the squeeze to control the downward pressure distance of the electric telescopic component. These three distances represent the size of the bag and the gap between the bag and the roll of cloth. The larger the gap, the greater the distance the electric telescopic component slides inward along the hollow guide tube, squeezing out more air. This allows for better downward pressure on plastic bags with different requirements for limiting, while avoiding excessive downward pressure distance that could cause the roll of cloth to be squeezed and deformed, thus improving the packaging quality of the roll of cloth.

[0026] 4. The locking clip and tube transmit airflow to the interior of the buffer ball through the air transmission tube, causing the locking clip and tube to fully compress the interior of the limiting collar. The buffer ball is located in the center of each pair of plastic bag center positioning rods, at the synchronous junction of airflow. This causes the four sets of plastic bag center positioning rods to be taut and stable under the compression of airflow. Thus, the binding of the rope and the airflow inside the packaging bag create resistance between the four sets of plastic bag center positioning rods, causing the four sets of plastic bag center positioning rods to share the pressure in each direction. This improves the stability of the plastic bag during bonding, reduces the shaking of the plastic bag during binding, and makes the binding tighter.

[0027] 5. The transmission component drives the auxiliary plastic bag placement component to return to its original position through the forward and reverse rotation of the connected motor. Then, multiple sets of plastic bag cutting components are driven by air pressure to move towards the center of the packaging bag to cut the packaging bag, thereby completing the packaging of the roll of cloth, improving the work efficiency of large cloth packaging, and the bundling and cutting do not affect each other.

[0028] 6. The packaging bag is opened by suction and moved to the pneumatic suction cup of the plastic bag. The hollow clamping plate of the plastic bag moves away from its original position because the auxiliary plastic bag placement component makes way for the winding frame. The other end of the packaging bag is still attracted and fixed by the pneumatic suction cup of the plastic bag, which facilitates the rolling of the cloth and the cutting of the plastic bag, replacing manual cutting and saving labor costs.

Detailed Implementation

[0051] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0052] like Figures 1-21 As shown, the automatic fabric packaging machine proposed in this invention includes an auxiliary protective box 6, a packaging bag conveyor frame 3 fixedly installed at one end of the auxiliary protective box 6, a conveying component 14 slidably installed at one end of the packaging bag conveyor frame 3, and a packaging bag 8 fixedly installed at one end of the conveying component 14 via a plastic bag placement component 15. The conveying component 14 moves along the track of the packaging bag conveyor frame 3 towards one end of the auxiliary protective box 6 via a conveying mechanism. The plastic bag placement component 15 moves the packaging bag 8 to a predetermined position to facilitate the sleeve installation of the fabric roll 7. It also includes:

[0053] A winding frame 19 is slidably installed inside the auxiliary protective box 6. One end of the winding frame 19 is rotatably connected to a turntable 35. A transmission belt 36 is wound around the outer surface of the turntable 35. A gear disk 37 is wound around the outer surface of the transmission belt 36. The gear disk 37 is rotatably installed on the outer surface of the winding frame 19. A rope rotating assembly 43 is fixedly connected to the end of the gear disk 37 away from the winding frame 19. An angle adjusting assembly 45 for adjusting the winding angle is rotatably connected to one end of the rope rotating assembly 43. A rope clamping assembly 44 for clamping the wire is provided at the top of the angle adjusting assembly 45. An electric telescopic cutting assembly 56 for cutting rope is fixedly connected to one end of the rope rotating assembly 43.

[0054] The main support plate 38 is inserted into the inner wall of the winding frame 19. An electric telescopic component 53 is fixedly connected inside the main support plate 38. A hollow guide tube 52 is slidably connected to one end of the electric telescopic component 53. The hollow guide tube 52 is fixedly installed at one end of the winding frame 19.

[0055] Four sets of plastic bag center positioning rods 39 are hinged to the outer surface of the main support plate 38. The ends of the four sets of plastic bag center positioning rods 39 away from the main support plate 38 are fixedly connected to protrusions that abut against the surface of the plastic bag.

[0056] A binding rope knotting assembly 40 is fixedly installed on the outer surface of the main support plate 38. Two sets of drive assemblies 41 are fixedly connected to the outer surface of the binding rope knotting assembly 40. A robotic arm assembly 42 is provided at one end of the drive assembly 41 and is hinged to the outer surface of the binding rope knotting assembly 40. A set of pushing components is provided on the rear area conveyor belt 2 opposite to the auxiliary protective box 6. The pushing components push the roll of cloth 7 into the inside of the packaging bag 8 to complete the looping. The winding frame 19 is moved to the position of the packaging bag 8 by the relative pushing mechanism. The four sets of plastic bag center positioning rods 39 are squeezed by the air pressure pushing mechanism on the surface of the main support plate 38. The pressure moves towards the center, causing the four sets of plastic bag center positioning rods 39 to adhere to the outer surface of the packaging bag 8. This causes the opening on the side of the packaging bag 8 used to store the rolled cloth 7 to gradually close and seal as the plastic bag center positioning rods 39 are squeezed. At the same time, as the air pressure drives the electric telescopic component 53 to retract into the hollow guide tube 52 through the main support plate 38, the four sets of plastic bag center positioning rods 39 gradually seal the packaging bag 8 while pressing it down. Before sealing, the airflow between the rolled cloth 7 and the packaging bag 8 is released, squeezing the airflow out of the packaging bag 8, thereby squeezing out the air inside the plastic bag. This facilitates the binding with ropes and avoids the bag bursting due to excessive airflow inside the bag during binding.

[0057] In this embodiment, a corresponding transmission component for transmitting ropes is fixedly connected to one end of the rear area transmission belt 2 away from the front area transmission belt 4. The rope is then transmitted to the rope clamping component 44 through the corresponding transmission component and clamped by the rope clamping component 44. After the packaging bag 8 is sealed by the four sets of plastic bag center positioning rods 39, as the turntable 35 drives the gear disk 37 to rotate through the transmission belt 36, the gear disk 37 drives the rope to rotate along the outer surface of the packaging bag 8 through the rope rotation component 43. At the same time, the angle adjustment component 45 drives the rope clamping component 44 to bend and rotate the packaging bag 8 through air pressure. The knotting action of the rope is completed by the deflection and recovery of the packaging bag 8.

[0058] For specific binding methods, please refer to [the relevant documentation]. Figures 16-21 As the rope is pulled by the rope clamping assembly 44 and rotates along the surface of the packaging bag 8, the two sets of robotic arm assemblies 42 remain perpendicular to the ground. (Reference) Figure 17 and Figure 18 The rope first adheres to the robotic arm assembly 42, then passes around it and continues towards the packaging bag 8. Next, the robotic arm assembly 42 deflects along the binding rope knot assembly 40 towards the packaging bag 8. At this point, both robotic arm assemblies 42 are horizontal to the ground, and the rope passes under the robotic arm assembly 42 and directly adheres to the surface of the packaging bag 8, forming the first loop. (Refer to...) Figure 19 Then the rope continues to wrap around the packaging bag 8 and onto the two sets of robotic arm components 42 that are now deflected and perpendicular to the ground, forming a second loop around the packaging bag 8. (Refer to...) Figure 20 Next, a set of robotic arm components 42, carrying the second loop of rope, moves away from the packaging bag 8. The second loop of rope is higher than the third loop. At this point, the rope forming the third loop on the packaging bag 8 passes under the first set of robotic arm components 42, meaning the two are not in contact. The rope is wrapped around the surface of the second set of robotic arm components 42. (Refer to...) Figure 21 The rope clamping component 44 pulls the rope to move in the opposite direction. At this time, the first set of robotic arm components 42 returns to its original position and clamps the rope driven by the rope clamping component 44. The packaging bag 8 then continues to be transported along the first set of ropes, and a knot is formed between the ropes. At the same time, the electric telescopic cutting component 56 extends, and the blade on its surface cuts the rope to complete the knot. This quickly completes the packaging of the roll of cloth, replacing manual binding. Compared with the traditional knotting method, it is more tightly bound and less likely to cause the roll of cloth to break free from the plastic bag. Example 2

[0059] like Figure 8-13As shown, based on Embodiment 1, the electric telescopic component 53 is fixedly connected to a fixed rod 49 inside the hollow guide tube 52. A multi-position positioning rod 33 with multiple sets of limiting holes on its surface is fixedly connected to the end of the fixed rod 49 away from the electric telescopic component 53. Multiple sets of pressure sensors 16 with telescopic functions are fixedly connected inside the hollow guide tube 52. The pressure sensors 16 are located in the limiting holes of the multi-position positioning rod 33. A telescopic positioning component 48 is slidably connected to one end of the multi-position positioning rod 33. The telescopic positioning component 48 is fixedly connected to the inner wall of the hollow guide tube 52. When the main support plate 38 moves the four sets of plastic bag center positioning rods 39 towards one end of the packaging bag 8 via the electric telescopic component 53, the electric telescopic component 53, the hollow guide tube 52, and the telescopic positioning component 48 form an electric telescopic device. The telescopic positioning component 48 uses multi-position positioning... When the rod 33 and the fixed rod 49 drive the electric telescopic component 53 to move into the hollow guide tube 52, the multi-position positioning rod 33 descends a set distance, and the limiting hole at one end of the multi-position positioning rod 33 squeezes the pressure sensor 16. The pressure sensor 16 transmits an electrical signal through the squeezing to control the downward pressure distance of the electric telescopic component 53. These three distances represent the size of the bag and the gap between the bag and the roll of cloth. The larger the gap, the greater the distance that the electric telescopic component 53 slides inward along the hollow guide tube 52, squeezing out more air. At the same time, it avoids the cloth being too long and clamping the roll of cloth inside the plastic bag due to the lack of a downward pressure distance limit, which would damage the appearance of the roll of cloth and prevent the rope from being tied tightly. This better limits the downward pressure of plastic bags with different requirements, while avoiding the roll of cloth being squeezed and deformed due to excessive downward pressure distance, thus improving the packaging quality of the roll of cloth. Example 3

[0060] like Figures 8-15As shown, based on the above embodiment 1 or 2, one end of the plastic bag center positioning rod 39 is hinged to a hinge assembly 46, and one end of the hinge assembly 46 is slidably connected to the outer surface of the plastic bag center positioning rod 39. Both ends of the pressure sensor 16 are hinged to corrugated rubber tubes 47. A locking clip and a tube 54 are snapped into the inside of the corrugated rubber tube 47. One end of the locking clip and the tube 54 is fixedly connected to an air transmission tube 55. One end of the air transmission tube 55 is fixedly connected to a buffer ball 50, and the outer surface of the buffer ball 50 is fixedly connected to a... The positioning ring 51, the air transmission tube 55, the fitting clip and tube 54, and the buffer ball 50 are all connected. As the four sets of plastic bag center positioning rods 39 move towards the center, the fitting clip and tube 54, the corrugated rubber tube 47, the air transmission tube 55, and the buffer ball 50 connect the four sets of plastic bag center positioning rods 39 into a relatively unified whole. This allows one pneumatic assembly to bend all four sets of plastic bag center positioning rods 39. The pneumatic assembly compresses one set of plastic bag center positioning rods 39, while simultaneously bending all four sets of plastic bag center positioning rods 39. When the center positioning rod 39 of the plastic bags moves, if the plastic bags vibrate during the binding process, the corrugated rubber tube 47 will be squeezed or pulled and shaken through the center positioning rod 39 of the plastic bags at the same end. The locking clip and tube 54 will be compressed by the corrugated rubber tube 47. The locking clip and tube 54 will then transmit airflow through the air transmission tube 55 to the inside of the buffer ball 50, causing the locking clip and tube 54 to fully compress the inside of the limiting collar 51. The buffer ball 50 will then be positioned between the center positioning rods 39 of each pair of plastic bags. At the center, where the airflow converges synchronously, the four sets of plastic bag center positioning rods 39 are kept in a stable state by the compressed airflow. The binding of the rope and the airflow inside the packaging bag 8 create resistance between the four sets of plastic bag center positioning rods 39, causing the four sets of plastic bag center positioning rods 39 to distribute the pressure they receive from each direction. This improves the stability of the plastic bag during bonding, reduces the shaking of the plastic bag during binding, and makes the rope more tightly bound because the plastic bag is less likely to deviate. Example 4

[0061] like Figures 1-9As shown, based on the above embodiments 1 or 2, a bidirectional guide rail 20 is fixedly connected to the inner wall of the auxiliary protective box 6. A guide assembly 27 is rotatably connected inside the bidirectional guide rail 20. A guide rod 28 is fixedly connected inside the guide assembly 27. An auxiliary plastic bag placement assembly 17 is fixedly connected to the outer surface of the guide rod 28. A rotating rope disc 29 is provided on the outer surface of the auxiliary plastic bag placement assembly 17. Multiple sets of hollow bending plates 30 are fixedly connected to the outer surface of the auxiliary plastic bag placement assembly 17. A plastic bag positioning assembly 31 is fixedly connected to one end of the rotating rope disc 29. A push rod 34 with telescopic function is slidably connected inside the plastic bag positioning assembly 31. A hollow plastic bag clamping plate 18 is fixedly connected to one end of the push rod 34. A plastic bag cutting assembly 3 is fixedly connected to one end of the plastic bag positioning assembly 31. 2. The packaging bag 8 is attached to the outer surface of the hollow plastic bag clamping plate 18. The packaging bag 8 is clamped by the hollow plastic bag clamping plate 18. When the roll of cloth 7 moves to the front of the packaging bag 8, the auxiliary plastic bag placement component 17 slides towards the position of the packaging bag 8 through the transmission component on the bidirectional guide rail 20. The winding frame 19 slides to the original position of the auxiliary plastic bag placement component 17 to make room for bundling. As the bundling comes into contact, the transmission component drives the auxiliary plastic bag placement component 17 to return to its original position through the forward and reverse rotation of the connected motor. Then, multiple sets of plastic bag cutting components 32 are driven by air pressure to move towards the center of the packaging bag 8 to cut the packaging bag 8, thereby completing the packaging of the roll of cloth, improving the work efficiency of large fabric packaging, and the bundling and cutting do not affect each other.

[0062] Meanwhile, a track clamping rod 22 is slidably connected to the outer surface of the bidirectional guide rail 20. A plastic bag positioning plate 21 is fixedly connected to one end of the track clamping rod 22 away from the bidirectional guide rail 20. Two sets of vertical guide rails 26 are fixedly connected to one end of the plastic bag positioning plate 21. A hollow block 23 is slidably connected between the two sets of vertical guide rails 26. A height adjustment rod 24 for adjusting the position of the clamped plastic bag is provided inside the hollow block 23. A plastic bag pneumatic suction cup 25 is fixedly connected to the bottom end of the height adjustment rod 24. A plastic bag pneumatic suction cup 25 is also fixedly connected to the bottom end of the vertical guide rail 26. The suction cup 25 is attached to the outer surface of the packaging bag 8, which is similar to a plastic garbage bag, sealed at one end and open at the other. The hollow plastic bag clamping plate 18 is also a pneumatic suction cup component. By adsorbing the packaging bag 8, it opens it up and moves it under the pneumatic suction cup 25. As a result, the hollow plastic bag clamping plate 18 moves away from its original position because the auxiliary plastic bag placement component 17 makes way for the winding frame 19. The other end of the packaging bag 8 is still adsorbed and fixed by the pneumatic suction cup 25, which facilitates the rolling of the cloth and the cutting of the plastic bag, replacing manual cutting and saving labor costs.
