Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a packaging consumables feeding device and an automatic packaging production line. Background Technology

[0002] Packaging equipment (such as strapping machines and stretch wrapping machines) is widely used in industrial production. Strapping machines use strapping tape to bundle and package goods, while stretch wrapping machines use wrapping film to wrap the goods. Therefore, packaging equipment requires a continuous supply of packaging materials during operation. Taking strapping machines as an example, they are typically equipped with a tape reel trolley to supply strapping tape. The tape rolls are placed on the reel trolley, and the tape is unwound and output for use by the strapping machine.

[0003] However, in actual use, when the strapping tape is used up, a new roll needs to be replaced. During operation, the operator needs to load the new roll onto the tape trolley and then thread the strapping tape into the packaging equipment.

[0004] During reel replacement, packaging equipment typically needs to be stopped to allow for manual threading of packaging materials, leading to reduced packaging efficiency. Furthermore, the unused leftover packaging materials from the previous reel are discarded, increasing packaging costs. Therefore, how can an automatic connection system for linking the beginning and end of packaging materials be designed to improve packaging efficiency and reduce costs? Utility Model Content

[0011] In one embodiment, the plurality of the material storage stations are arranged side by side in a horizontal direction; Alternatively, multiple storage stations may be arranged longitudinally side by side.

[0012] In one embodiment, the storage rack is further provided with a spare workstation, which is configured to store packaging consumables; The storage rack is also equipped with a pushing component, which is configured to push the packaging consumables in the standby station into the corresponding storage station.

[0013] In one embodiment, the storage rack is further provided with a lifting assembly and a support frame. The lifting assembly includes a lifting component and a lateral movement component.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] Example 1, as Figure 1 and Figure 2 As shown, in one embodiment of this application, the packaging consumables feeding device includes: A storage rack 1 is provided with two storage stations 11, which are configured to store packaging consumables 100. A connecting mechanism 2 is provided with a connecting part 21; the connecting part 21 is configured to connect the tail of the packaging material 100 in the storage station 11 when it is in the feeding state to the head of the packaging material 100 in the storage station 11 when it is in the standby state. The retaining mechanism 3 is provided with a retaining part 31; the retaining part 31 is configured to hold the head of the packaging consumable 100 in the storage station 11 in the standby state at the connecting part 21, so that the tail of the packaging consumable 100 in the storage station 11 in the feeding state and the head of the packaging consumable 100 in the storage station 11 in the standby state form an overlap area 101 at the connecting part 21; Along the feeding and conveying direction of the packaging consumables 100, the storage station 11 and the connecting part 21 are arranged in sequence.

[0024] Specifically, during use, each storage station 11 contains packaging consumables 100. One station serves as a "supply status station" for storing the packaging consumables 100 that are about to be put into use; the other station serves as a "standby status station" for storing the spare packaging consumables 100 that are to be switched over.

[0025] When used for the first time, the packaging material 100 in the storage station 11 of the "feeding status station" is fed outward, and the packaging material 100 is put into the packaging equipment 200 through the connecting part 21.

[0026] For the packaging material 100 in the standby position, the operator needs to lead out the head of the packaging material 100 and guide it manually so that the head of the packaging material 100 is fixed by the holding part 31 of the holding mechanism 3. Thus, the head of the packaging material 100 is fixed near the connecting part 21 of the connecting mechanism 2 (at this time, it is not in contact with the connecting part 21 and is only in the waiting-to-connect state), thus completing the pre-positioning of the standby packaging material.

[0027] During the packaging process of the packaging equipment 200, the packaging consumables 100 in the storage station 11 under the material supply state are continuously output and transported into the packaging equipment 200 to meet the requirements of the packaging equipment 200 for packaging goods.

[0028] like Figure 8 As shown, the packaging consumable 100 feeding device further includes a control mechanism 4, which includes a controller 41 and a detector 42. The controller 41 is connected to the detector 42. The detector 42 is configured to detect the tail of the packaging consumable 100 in the storage station 11 when it is in the feeding state. The controller 41 is configured to control the connection mechanism 2 to work after the detector 42 detects the tail of the packaging consumable 100 in the storage station 11 when it is in the feeding state.

[0029] Specifically, detector 42 can detect the remaining amount of packaging material 100 in storage station 11 during the feeding state, and detector 42 can be a photoelectric switch or a position switch.

[0030] Taking a position switch as an example, the position switch is arranged between the connecting part 21 and the storage station 11. When the packaging material 100 is continuously fed out, the position switch is squeezed by the output packaging material 100. At this time, it is determined that the packaging material 100 has not been used up. When the tail of the packaging material 100 leaves the position switch, the position switch will send a trigger signal to the controller 41 after it is reset without the squeezing of the packaging material 100. After receiving the trigger signal sent by the position switch, the controller 41 will control the connecting mechanism 2 to operate. The connecting part 21 of the connecting mechanism 2 connects the tail of the packaging material 100 in the feeding state with the head of the packaging material 100 in the standby state.

[0031] Taking a photoelectric switch as an example, the photoelectric switch is arranged between the connecting part 21 and the storage station 11. When the packaging material 100 is continuously supplied, the photoelectric switch is blocked by the output packaging material 100. At this time, it is determined that the packaging material 100 has not been used up. When the tail of the packaging material 100 leaves the photoelectric switch, the photoelectric switch will send a trigger signal to the controller 41 when it is no longer blocked by the packaging material 100. After receiving the trigger signal sent by the photoelectric switch, the controller 41 will control the connecting mechanism 2 to operate. The connecting part 21 of the connecting mechanism 2 connects the tail of the packaging material 100 in the feeding state with the head of the packaging material 100 in the standby state. Alternatively, a perforation design can be made at the end of the packaging material 100 (for example, multiple through holes are opened at the end of the packing strap along the length direction, and a certain length of packing strap is reserved behind the through holes; in this way, the connecting part 21 and the photoelectric switch are arranged in sequence along the conveying direction of the packing strap). After the photoelectric switch detects the through hole, the photoelectric switch will send a trigger signal to the controller 41 so as to control the action of the connecting mechanism 2 through the controller 41.

[0032] Taking the packaging material 100 as a packing tape roll as an example, the packing tape roll is unwound and conveyed outwards. The packing tape is then conveyed to the packaging equipment 200 (packing machine) via the connecting part 21. After the packaging equipment 200 is started, the roll in the feeding state station begins to be fed, and the packaging material 100 continues to move along the conveying direction. After passing through the connecting part 21 of the connecting mechanism 2, it is finally conveyed to the packaging equipment 200 to meet the packaging operation requirements. The roll in the standby state station remains stationary, and the packaging material 100 at its head is always fixed in a preset position near the connecting part 21 by the holding part 31 of the holding mechanism 3. At this time, the connecting part 21 of the connecting mechanism 2 is in a non-working state and does not interfere with the normal feeding of the roll in use.

[0033] When detector 42 detects that the material roll at the feeding station is about to run out, controller 41 will control the connecting mechanism 2 to operate. The material roll at the feeding station continues to be fed, and the tail of the packaging material 100 moves to the connecting part 21 of the connecting mechanism 2; at the same time, the head of the packaging material 100 at the standby station is fixed by the holding part 31 and is already at the connecting part 21, forming an overlap area 101 between the tail of the packaging material 100 in the feeding state and the head of the packaging material 100 in the standby state. The connecting mechanism 2 firmly connects the overlapping tail and head of the packaging material 100 into one unit through the connecting part 21, completing the automatic connection.

[0034] After the tail of the packaging consumable 100 in the feeding state is connected to the head of the packaging consumable 100 in the standby state, the standby roll is switched to the feeding state to ensure a continuous supply of packaging material to the packaging equipment 200. The operator can then place a new standby roll into an idle storage station 11 as a backup roll. At the same time, the pre-processing of the standby roll is repeated so that the head of the packaging consumable 100 of the standby roll is held in position at the connection part 21 by the holding part 31 of the holding mechanism 3, preparing for the next switchover.

[0035] Through the above-mentioned cyclical operation, the packaging consumables 100 feeding device realizes a continuous feeding process of "in use - standby - automatic connection - new standby replenishment", without the need to stop the machine throughout the process, which greatly improves the continuity and efficiency of the packaging operation.

[0036] In one embodiment, the entity representing the holding part 31 can have various structural forms.

[0037] For example: Figure 5 As shown, the holding part 31 is a gripper, which is configured to hold the head of the packaging material 100 in the storage station 11 when it is in standby state.

[0038] Specifically, the gripper can hold the head of the packaging material to ensure that the head of the packaging material remains fixed at the connecting part 21. When the holding part 31 adopts a gripper structure, the gripper can be opened and closed by mechanical drive (such as a cylinder or motor). For details, refer to the driving method of grippers in conventional technology, which will not be elaborated here. In the standby state, after the operator places the new packaging material 100 in the standby storage station 11, the new packaging material 100 is pulled to the gripper, and the gripper can hold the head of the packaging material 100 (such as the end of a strapping band or the end of a packaging film). On the one hand, the gripping force of the gripper fixes the head of the packaging material 100 in the preset position of the connecting part 21; on the other hand, the gripper reliably holds the head of the packaging material to ensure that the tail and the head form an overlap area 101 of a preset length at the connecting part 21. When the connecting part 21 of the connecting mechanism 2 connects the overlap area 101, it ensures that the head and tail remain in an overlapping state to improve the reliability of the connection.

[0039] Or, such as Figure 4 As shown, the holding part 31 is a suction cup, which is configured to pick up the head of the packaging material 100 in the storage station 11 when it is in standby state.

[0040] Specifically, the suction cup can adhere to the surface of the packaging material 100, keeping the head of the packaging material fixed at the connection part 21. The packaging material 100 can be a strapping, packaging film, etc., and its surface is generally smooth to meet the requirements of reliable suction cup adhesion. When the holding part 31 adopts a suction cup (such as a vacuum suction cup) structure, the suction cup acts on the head of the packaging material 100 through the principle of negative pressure adhesion. For packaging materials 100 with softer textures (such as film-type consumables) or flat surfaces, the suction cup can achieve stable adhesion without damaging the material surface.

[0041] Or, such as Figure 3 As shown, the holding part 31 is a conveying pipe, and the conveying channel is configured to allow the packaging consumable 100 of the material roll in the material storage station 11 in the feeding state to pass through and be conveyed. The conveying channel is also configured to allow the head of the packaging consumable 100 in the material storage station 11 in the standby state to be inserted into the conveying channel.

[0042] Specifically, the conveying pipe allows the packaging consumables 100 in the feeding state to pass through, and the head of the packaging consumables 100 in the standby state is also inserted into the conveying pipe in the direction of the consumables' conveying.

[0043] When the holding unit 31 uses a conveying pipe, a conveying channel is formed inside the conveying pipe. In the feeding state, the packaging material 100 in the feeding state can continuously travel along the conveying channel to the packaging equipment 200; while in the standby state, the head of the packaging material 100 in the standby state can be pre-inserted into the conveying channel. The head of the packaging material 100 in the standby state will contact the packaging material 100 in the feeding state within the conveying channel, generating a certain amount of friction. Under the action of friction, it is ensured that the head of the packaging material 100 will not detach from the conveying pipe. At the same time, this friction will not pull the packaging material 100 in the standby state outwards. The conveying channel is suitable for strip-shaped packaging materials 100 with a certain degree of rigidity (such as strapping).

[0044] In one embodiment, such as Figure 1 As shown, the holding mechanism 3 further includes a moving part 32, the holding part 31 is disposed on the moving part 32, and the moving part 32 is movable relative to the connecting part 21.

[0045] Specifically, the retaining mechanism 3 is equipped with a movable part 32, and the retaining part 31 is disposed on the movable part 32. The movable part 32 can move relative to the connecting part 21. By dynamically adjusting the relative position of the retaining part 31 and the connecting part 21, the positioning accuracy of the packaging consumable 100 head and the operational adaptability of the connecting mechanism 2 are further optimized.

[0046] The moving part 32 may include a cylinder or a linear motor 321, which can drive the holding part 31 to move closer to or away from the connecting part 21. After the tail of the packaging consumable 100 is connected to the holding part 31, the moving part 32 drives the holding part 31 to reciprocate on the storage rack 1. In actual use, the holding part 31 mounted on the moving part 32 can be a gripper or a suction cup. When the head of the packaging consumable 100 in the standby state is gripped or attracted by the holding part 31, the moving part 32 drives the holding part 31 to move closer to the connecting part 21.

[0047] By adding the movable part 32, the holding part 31 can be moved away from the connecting part 21 during the process of the operator threading the head of the packaging consumable 100 in the standby state, thereby leaving enough space for the operator to place the head of the packaging consumable 100 on the holding part 31.

[0048] In one embodiment, the physical representation of the connecting portion 21 can be configured according to the specific connection method of the packaging consumables 100 in the overlapping area 101, as described below with reference to the accompanying drawings.

[0049] like Figure 2 As shown, the connecting part 21 includes two friction blocks 211 arranged opposite to each other; the connecting mechanism 2 also includes a friction driving component 212, which is connected to at least one of the friction blocks 211. The friction driving component 212 is configured to drive the two friction blocks 211 to move relative to each other so as to weld the packaging consumables 100 of the overlapping area 101 together by friction.

[0050] Specifically, the packaging material 100 forming the overlapping area 101 is located between two friction blocks 211. When it is necessary to connect the tail of the packaging material 100 to the head of another packaging material 100, the two friction blocks 211 press the two layers of packaging material 100 together. Then, under the driving action of the friction driving component 212, the two friction blocks 211 move relative to each other to rub the two layers of packaging material 100 in the overlapping area 101. The heat generated during the friction process melts the surface of the packaging material 100 (such as thermoplastic materials like PP and PET) in the overlapping area 101. After the friction driving component 212 stops moving, the friction blocks 211 remain clamped until the material cools and solidifies, forming a strong welded joint and completing the end-to-end connection.

[0051] There are several ways in which the friction drive component 212 drives the friction block 211 to reciprocate. For example, it can adopt the welding module inside the packing head of a conventional packing machine, such as the welding module structure in Chinese Patent Publication No. CN220410986U. The friction drive component 212 includes a motor, a cam 2121, and a spring 2122. The motor drives the cam 2121 to rotate, thereby driving the friction block 211 to reciprocate. The cam 2121 is mounted on the motor shaft, and the spring 2122 is provided between the cam 2121 and the friction block 211. After the controller 41 controls the motor to run, the cam 2121 applies power to the friction block 211 through the spring 2122, causing the friction block 211 in contact with the spring 2122 to move relative to the other friction block 211, thereby welding the packaging consumables 100 in the overlapping area 101 together. The packaging consumables 100 can be PP or PET strapping.

[0052] Alternatively, the connecting part 21 may be a welding gun configured to weld the packaging consumables 100 of the overlapping area 101 together.

[0053] Specifically, if the packaging material 100 uses steel strips, an electric welding gun is needed to weld the steel strips together in the overlapping area 101. During the automatic welding process, a cylinder can be used to drive the welding gun closer to or further away from the overlapping area 101.

[0054] Or, such as Figure 5 As shown, the connecting part 21 is an electric heating element 213; the connecting mechanism 2 also includes a moving drive component 214, the electric heating element 213 is disposed on the moving drive component 214, the moving drive component 214 is configured to drive the electric heating element 213 to move closer to or away from the overlapping area 101, and the electric heating element 213 is configured to heat seal the packaging consumables 100 of the overlapping area 101 together.

[0055] Specifically, the tail and head of the packaging material 100 in the overlapping area 101 can be heated by the electric heating element 213 to heat-seal the two layers of packaging material 100 together. The electric heating element 213 can be an electric heating plate or an electric heating tube, and the moving drive component 214 can be a cylinder. When it is necessary to heat-seal the packaging material 100 in the overlapping area 101, the moving drive component 214 drives the electric heating element 213 to approach the packaging material 100. After the electric heating element 213 is energized, it generates heat and transfers the heat to the overlapping area 101 through direct contact or close-range radiation, causing the contact surface of the thermoplastic packaging material 100 (such as PE film or PP strapping) to melt, so that the packaging material 100 in the overlapping area 101 is heat-sealed together.

[0056] Among them, such as Figure 5As shown, the connecting mechanism 2 further includes a heat insulation body 215, and the electric heating body 213 and the heat insulation body 215 are arranged opposite to each other; the packaging material 100 in the overlap area 101 is located between the electric heating body 213 and the heat insulation body 215. After the electric heating body 213 is energized, the packaging material 100 is sandwiched between the electric heating body 213 and the heat insulation body 215, thereby achieving heat sealing of the packaging material 100 in the overlap area 101. Or, as Figure 6 As shown, the connecting mechanism 2 also includes two pressure plates 216, with an electric heating element 213 located between the two pressure plates 216. Each pressure plate 216 is equipped with a cylinder, which can drive the pressure plates 216 to move closer or further apart. When the packaging material 100 in the overlapping area 101 needs to be heat-sealed, the cylinder drives the pressure plates 216 to move closer together, causing the electric heating element 213 to be sandwiched between the two layers of packaging material 100. After the contact surfaces of the packaging material 100 melt, the electric heating element 213, driven by the moving drive component 214, detaches from between the two layers of packaging material 100. The two layers of packaging material 100 are then pressed together again by the pressure plates 216, thus heat-sealing the packaging material 100 in the overlapping area 101 together.

[0057] In one embodiment, such as Figure 2 As shown, multiple storage stations 11 are arranged side by side horizontally. Alternatively, multiple storage stations 11 are arranged side by side vertically.

[0058] In one embodiment, such as Figure 7 As shown, the storage rack 1 is also provided with a spare station 12, which is configured to store packaging consumables 100; the storage rack 1 is also provided with a pushing component 13, which is configured to push the packaging consumables 100 in the spare station 12 into the corresponding storage station 11.

[0059] Specifically, the standby station 12 is located outside the storage station 11. The standby station 12 can also hold packaging consumables 100. After the packaging consumables 100 in one of the storage stations 11 are used up, the pushing component 13 will push the packaging consumables 100 in the standby station 12 to the storage station 11. The pushing component 13 can be a cylinder or a hydraulic cylinder. Taking a cylinder as an example, the piston rod of the cylinder is equipped with a push plate. The cylinder pushes the packaging consumables 100 in the standby station 12 to the vacant storage station 11 through the push plate, so as to facilitate the rapid replenishment of packaging consumables 100 to the storage station 11.

[0060] In one embodiment, such as Figure 9As shown, the storage rack 1 is also provided with a lifting assembly 14 and a support frame 15. The lifting assembly 14 includes a lifting component 141 and a lateral movement component 142. The lateral movement component 142 is disposed on the lifting component 141, and the support frame 15 is disposed on the lateral movement component 142. The lifting assembly 14 is configured to drive the support frame 15 to move up and down, and is also configured to drive the support frame 15 to move horizontally. The support frame 15 is configured to carry the packaging consumables 100.

[0061] Specifically, in order for the lifting assembly 14 to move the support frame 15 up and down, so that packaging materials 100 can be placed above the same storage station 11 via the support frame 15, and after the packaging materials 100 in the storage station 11 are used up, the lifting assembly 141 drives the lateral movement assembly 142 to move downward, so that the packaging materials 100 on the support frame 15 are placed in the storage station 11. At this time, the lateral movement assembly 142 pulls the support frame 15 out from the bottom of the packaging materials 100. The lifting assembly 141 can be represented by a vertically arranged cylinder, and the lateral movement assembly 142 can be represented by a horizontally arranged cylinder.

[0062] Similarly, such as Figure 10 As shown, the storage rack 1 is also provided with a lifting frame 16, which can move up and down relative to the storage rack 1. The lifting frame 16 is also provided with a clamp 17, which is configured to hold the packaging consumables 100.

[0063] Specifically, the clamp 17 on the lifting frame 16 can hold the packaging consumable 100 and place it above the storage station 11. When the packaging material in the storage station 11 is used up, the lifting frame 16, driven by the hydraulic cylinder, moves the packaging consumable 100 down through the clamp 17 and places it in the storage station 11. The specific structural configuration of the clamp 17 is based on its ability to hold the corresponding packaging consumable 100, and is not limited here.

[0064] In one embodiment, such as Figure 9 As shown, the storage rack 1 is also provided with an inner support assembly 18 at the storage station 11. The inner support assembly 18 includes an inner support shaft 181, which is vertically arranged on the storage rack 1 and is configured to be inserted into the material roll.

[0065] Specifically, when packaging material 100 is wound into a roll, in order to effectively support the roll during the unwinding process, an inner support shaft 181 can be provided on the storage rack 1. After the roll is placed on the inner support shaft 181, the inner support shaft 181 expands to reliably support the roll. The inner support shaft 181 can rotate on the storage rack 1 to meet the requirement of smooth unwinding of the roll. The physical manifestation of the inner support shaft 181 can be a support shaft structure with expansion function, such as an air expansion shaft, and is not limited here.

[0066] The storage rack 1 is also provided with an external pressure assembly 19 at the storage station 11. The external pressure assembly 19 includes an external pressure drive 191, a support frame 192 and an external pressure roller 193. The external pressure roller 193 is vertically arranged and rotatably mounted on the support frame 192. The external pressure drive 191 is configured to drive the support frame 192 to move closer to or away from the material roll.

[0067] Specifically, to ensure the smooth unwinding and output of packaging material 100, an external pressure component 19 can be installed on the storage rack 1. The external pressure roller 193 of the external pressure component 19 can press against the surface of the material roll. Taking a packing tape roll as an example, during the rotation of the packing tape roll, in order to prevent the roll from collapsing due to the stretching of the packing tape itself in the final stage of unwinding, the external pressure roller 193 can be used to press the packing tape from the outside to improve the reliability of unwinding.

[0068] This embodiment also provides an automatic packaging production line, including packaging equipment 200 and the above-mentioned packaging consumables 100 feeding device; The packaging material 100 feeding device is configured to feed the packaging material 100 to the packaging equipment 200.

[0069] Specifically, the packaging equipment 200 can be conventional equipment such as a strapping machine or a stretching machine, and the corresponding packaging consumables 100 are matched with the type of packaging equipment 200. For example, the packaging consumables 100 corresponding to a strapping machine are strapping tape, while the packaging consumables 100 corresponding to a stretching machine are stretch film.

[0070] Multiple storage stations 11 are set on the storage rack 1, each storing a roll of packaging material. A connecting mechanism 2 and a holding mechanism 3 are provided. The holding part 31 of the holding mechanism 3 can pre-hold the head of the spare packaging material 100 at the connecting part 21. When the roll in the feeding state is about to run out, its tail end of the packaging material 100 is conveyed to the connecting part 21, forming an overlap area 101 with the head of the spare packaging material 100 at the connecting part 21. The connecting part 21 of the connecting mechanism 2 automatically connects the two together. The entire connection process requires no manual intervention and no machine shutdown, ensuring a continuous supply of packaging material 100 to the packaging equipment 200, effectively avoiding production interruptions caused by roll changes and significantly improving packaging efficiency. The tail end of the feeding roll and the head of the spare roll are automatically connected through the connecting mechanism 2, allowing the tail of the previous roll to seamlessly connect with the head of the new roll. The tail can continue to participate in the packaging process, avoiding waste. Meanwhile, the automatic connection eliminates the need for manual cutting or handling of excess materials, further reducing material waste and thus lowering packaging costs.

[0071] Furthermore, in actual use, to ensure a continuous supply of packaging material 100 to the packaging equipment 200 during the connection process of the overlapping area 101 via the connecting part 21, a material buffer mechanism 300 can be provided between the packaging equipment 200 and the material feeding device. This material buffer mechanism 300 can buffer a certain length of packaging material 100, allowing for a continuous supply of the buffered material 100 to the packaging equipment 200 during the connection process via the connecting part 21, thus meeting the requirements of continuous production. Taking strapping as an example, the material buffer mechanism 300 can utilize a pulley system as described in Chinese Patent Publication Nos. CN209757613U and CN208086089U. Similarly, for stretch film, a strapping buffer structure can also be used, with the pulleys in the pulley system employing film rollers. Further details are omitted here. Furthermore, in order to guide the packaging consumables 100 to the consumables buffer mechanism 300, the storage rack 1 is also provided with several rotatable guide rollers 10 as needed, which guide the packaging consumables 100 to be output outward.

[0072] Meanwhile, in order to ensure that the packaging consumables 100 at the connecting part 21 remain stationary during the connection of the packaging consumables 100 in the overlapping area 101, the packaging consumables 100 feeding device is also provided with a pressing mechanism 5. The pressing mechanism 5 includes a pressing block 51, which is arranged between the connecting part 21 and the consumables buffer mechanism 300. The pressing block 51 presses against the packaging consumables 100 so that the connecting part 21 is not affected by the outward output of the packaging consumables 100 by the consumables buffer mechanism 300 when connecting the packaging consumables 100 in the overlapping area 101. The clamping mechanism 5 also includes a guide post 52. The packaging consumable 100 is guided and conveyed via the guide post 52. The packaging consumable 100 is also located between the guide post 52 and the clamping block 51. The cylinder drives the clamping block 51 to approach the guide post 52. The clamping block 51 presses the packaging consumable 100 onto the guide post 52 so that the connecting part 21 is not affected by the outward conveying of the packaging consumable 100 by the consumable buffer mechanism 300 during the process of connecting the packaging consumable 100 in the overlapping area 101.

[0073] The automated connection and feeding mechanism reduces manual roll changing, lowering the workload for operators. The feeding device ensures uninterrupted supply of packaging materials, matching the continuous production needs of automated packaging lines. It can be widely used in packaging equipment such as strapping machines and stretch wrapping machines, enhancing the equipment's applicability and versatility in various production scenarios.
