Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical equipment, and in particular to polyvinyl chloride feeding equipment for an aluminum plastic machine, the aluminum plastic machine and a use method thereof. Background Art

[0002] With the continuous advancement of pharmaceutical technology, aluminum-plastic molding machines, particularly high-speed ones, have become increasingly popular. During the production process, when the polyvinyl chloride (PVC) roller runs out of PVC, the machine must be stopped, replaced with a new roller, and then restarted. However, as high-speed aluminum-plastic molding machines consume increasing amounts of PVC, the need for roller replacement is increasing. Replacing a new roller can often take up to five minutes, requiring dozens or even more replacements for a single batch of product, severely impacting the proper functioning of roller-type blister packaging machines.

[0003] To address the above-mentioned issues, publication number CN202208555U discloses a PVC backup device. This solution adds a forward film feed mechanism and a film storage box, whereby the forward film feed mechanism delivers PVC to the film storage box for pre-storage. Subsequently, the rear film feed mechanism delivers the PVC in the film storage box to the aluminum-plastic molding machine. This arrangement allows the film storage box to pre-store some PVC material, allowing the film storage box to continuously supply PVC to the aluminum-plastic molding machine while the PVC roll core is being replaced. However, during the replacement process, the PVC is prone to positional offset. The prior art PVC feeding equipment for aluminum-plastic molding machines is unable to address this PVC positional offset, which can affect normal production operations and also result in PVC material waste. To reduce material waste, those skilled in the art urgently need a new PVC feeding device for aluminum-plastic molding machines that can address the problem of PVC positional offset, resulting in PVC material waste and reduced production efficiency. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the existing technology lacks a solution to the problem that polyvinyl chloride is easily offset when the polyvinyl chloride core is replaced without stopping the machine, resulting in polyvinyl chloride material waste and reduced production efficiency. To this end, the present invention provides a polyvinyl chloride feeding device for an aluminum plastic machine, comprising: A material receiving shaft is used to carry a polyvinyl chloride core, and the polyvinyl chloride core is driven to rotate and is arranged on the material receiving shaft to feed the aluminum-plastic packaging machine; The carrying platform is used to carry the polyvinyl chloride tape, so that the operator can conveniently cut the polyvinyl chloride tape on the carrying platform; The brake mechanism is arranged on the supporting platform and is driven to be connected to the polyvinyl chloride tape output by the material receiving shaft, and is used to provide a dragging force to the polyvinyl chloride tape to prevent the polyvinyl chloride tape from shifting in its lateral direction when the polyvinyl chloride core is replaced or the polyvinyl chloride feeding equipment is in operation.

[0005] Optionally, the dragging force applied by the brake mechanism to the polyvinyl chloride tape during the feeding process of the polyvinyl chloride feeding equipment is smaller than the dragging force applied by the brake mechanism to the polyvinyl chloride tape during the replacement of the polyvinyl chloride roll core by the polyvinyl chloride feeding equipment.

[0006] Optionally, the brake mechanism comprises two groups, each comprising: a first elastic pressure strip and a second elastic pressure strip arranged along the width direction of the polyvinyl chloride tape; the first elastic pressure strip and the second elastic pressure strip are driven to move toward the supporting platform to compress the polyvinyl chloride tape; A feeding gap for the polyvinyl chloride tape to pass through is provided between the first elastic pressure strip, the second elastic pressure strip and the supporting platform.

[0007] Optionally, a feeding roller for guiding the polyvinyl chloride tape into the second elastic strip is further provided between the first elastic strip and the second elastic strip.

[0008] Optionally, the feed roller is arranged adjacent to the second elastic strip, and the feed roller is driven to rotate to transfer the polyvinyl chloride tape to the brake mechanism.

[0009] Optionally, the brake mechanism further includes: an adjusting component for respectively adjusting the drag force of the first elastic pressure strip and the second elastic pressure strip toward the supporting platform, the adjusting component being used to drive the first elastic pressure strip or the second elastic pressure strip to move toward the supporting platform; and / or, The first elastic strip and / or the second elastic strip are made of silicone; and / or, The first elastic pressure strip and the second elastic pressure strip are respectively arranged at two ends of the supporting platform along the horizontal direction and are located in the width direction of the polyvinyl chloride belt.

[0010] Optional PVC feeding equipment for aluminum plastic machine also includes: The residual material carrying roller is arranged in the discharge direction of the carrying platform and is used to carry the remaining polyvinyl chloride tape on the polyvinyl chloride core; the polyvinyl chloride tape is folded in half and overlapped on the residual material carrying roller to continuously feed the aluminum-plastic packaging machine.

[0011] Optional PVC feeding equipment for aluminum plastic machine also includes: The material receiving container is arranged corresponding to the residual material carrying roller and is used for accommodating the polyvinyl chloride tape overlapped on the residual material carrying roller.

[0012] Optional PVC feeding equipment for aluminum plastic machine also includes: a feed turning roller, disposed between the material receiving shaft and the supporting platform, for transferring the polyvinyl chloride tape to the brake mechanism of the supporting platform; and / or, A discharging turning roller is arranged between the bearing platform and the residual material bearing roller, and is used to move the polyvinyl chloride tape out of the brake mechanism.

[0013] Optionally, the feed turning roller and the discharge turning roller are respectively provided with anti-deviating clamping rings for limiting the position of the polyvinyl chloride tape; and / or, The supporting platform is provided with a cutting groove, and the cutting groove is used to accommodate a cutting knife so that an operator can cut the polyvinyl chloride tape.

[0014] An aluminum-plastic molding machine, comprising: a polyvinyl chloride feeding device for the aluminum-plastic molding machine; and Aluminum-plastic packaging machine.

[0015] The method for using the polyvinyl chloride feeding equipment of the aluminum plastic machine includes the following steps: Step S1: when the remaining amount of the polyvinyl chloride core on the material receiving shaft is insufficient, the aluminum-plastic packaging machine is not stopped and the polyvinyl chloride tape on the supporting platform is dragged to pull out the remaining polyvinyl chloride tape on the polyvinyl chloride core to form a folded polyvinyl chloride tape, which is overlapped on the residual material carrying roller, and then the folded polyvinyl chloride tape is transferred to the material receiving container; the aluminum-plastic packaging machine is continuously fed by the folded polyvinyl chloride tape in the material receiving container; Step S2, cutting the polyvinyl chloride tape at the root of the polyvinyl chloride core that needs to be replaced; Step S3: replacing the polyvinyl chloride core on the material receiving shaft without stopping the aluminum-plastic packaging machine, and winding the polyvinyl chloride tape on the polyvinyl chloride core onto the feed turning roller; Step S4, controlling the brake mechanism to press and fix the polyvinyl chloride tape, and ensuring that the pressure of the brake mechanism close to the discharge turning roller does not prevent the polyvinyl chloride tape from normally entering the discharge turning roller; Splice the newly replaced PVC tape and the original PVC tape together; Step S5, controlling the brake mechanism to release the clamping fixation, and driving the material receiving shaft to flip, winding the polyvinyl chloride tape in the material receiving container onto the material receiving shaft, and completing the polyvinyl chloride feeding work without stopping the aluminum-plastic packaging machine.

[0016] Optionally, in step S4, the specific steps of splicing the newly replaced polyvinyl chloride tape and the original polyvinyl chloride tape together include: Overlapping the newly replaced polyvinyl chloride tape with the original polyvinyl chloride tape, and pressing and fixing the polyvinyl chloride tape on the supporting platform by the brake mechanism; cutting the overlapping portion of the newly replaced polyvinyl chloride tape and the original polyvinyl chloride tape and discarding the cut polyvinyl chloride tape; Connect the new PVC tape and the original PVC tape together with tape.

[0017] The technical solution of the present invention has the following advantages: 1. As high-speed aluminum-plastic molding machines utilize increasing amounts of PVC, the need to replace PVC rolls is increasing, severely impacting the proper operation of roller-type blister aluminum-plastic packaging machines. To effectively replace PVC rolls without stopping the machine and address the issue of the PVC tape easily shifting during roll replacement, the present invention provides a support platform to support the PVC tape. Furthermore, a brake mechanism is mounted on the support platform. This brake mechanism is connected to the PVC tape and provides a drag force to the tape. This brake mechanism effectively limits and secures the PVC tape on the support platform, preventing it from shifting during cutting and splicing. This could cause the tape to shift during splicing, impacting packaging quality, leading to PVC material waste, and reducing production efficiency. Addressing this issue effectively prevents chemical material waste, maximizes chemical material utilization, improves raw material efficiency, and avoids material waste.

[0018] 2. In the present invention, during operation of the aluminum-plastic packaging machine, the brake mechanism also applies a dragging force to the PVC tape on the support platform. This dragging force effectively tightens the PVC tape, preventing it from shifting during normal operation of the aluminum-plastic packaging machine. Furthermore, during operation, the brake mechanism applies a relatively low braking force to ensure the normal advancement of the PVC tape. When the PVC feeding equipment is replacing the PVC core, the brake mechanism applies a relatively high dragging force to secure the PVC tape in place, ensuring that the tape does not shift when a new PVC core is replaced, thereby preventing disruption to normal production.

[0019] 3. In the present invention, a first elastic strip and a second elastic strip are respectively provided at both ends of the support platform in the longitudinal direction. The first elastic strip and the second elastic strip can be driven to press the polyvinyl chloride belt on the support platform, thereby generating the aforementioned drag force on the polyvinyl chloride belt.

[0020] 4. In the present invention, the operator can, as needed, install a feed roller between the first and second elastic strips, near the second elastic strip. This feed roller effectively guides the PVC tape into the brake mechanism located near the discharge turning roller. The second elastic strip applies a compressive force to the PVC tape within the brake mechanism, thereby dragging the tape. Furthermore, the feed roller can flatten the PVC tape, preventing it from sticking.

[0021] 5. In the present invention, the two adjustment components corresponding to the first and second elastic pressure strips, respectively, allow for quick and accurate adjustment of the pressure applied by the pressure strips to the PVC tape. The operator can adjust the drag force of the brake mechanism using these adjustment components as needed.

[0022] 6. In the present invention, a residual material carrying roller is provided in the discharge direction of the supporting platform. When the operator needs to replace the PVC core, the remaining PVC tape on the PVC core to be replaced can be pulled out to form a folded PVC tape, which is overlapped on the residual material carrying roller. The residual material carrying roller then carries the remaining PVC tape. The length of the folded PVC tape carried on the residual material carrying roller is effectively shortened by half, making it easier to store and less likely to get entangled. At the same time, the residual material carrying roller allows the PVC tape to be neatly bent and overlapped for storage, effectively preventing the PVC tapes from sticking together.

[0023] 7. In the present invention, a material receiving container is provided below the residual material carrying roller, and the material receiving container can effectively accommodate the polyvinyl chloride tape overlapped on the residual material carrying roller, thereby preventing the polyvinyl chloride tape from falling to the ground.

[0024] 8. In the present invention, the anti-deviating collar can effectively limit the position of the polyvinyl chloride belt, thereby preventing the polyvinyl chloride belt from being displaced.

[0025] 9. In the present invention, by providing the above-mentioned cutting groove on the carrying platform, it can effectively facilitate the operator to perform cutting operations on the polyvinyl chloride tapes overlapped on the carrying platform.

[0026] 10. The aluminum-plastic machine provided by the present invention comprises: a polyvinyl chloride feeding device for the aluminum-plastic machine and an aluminum-plastic packaging machine. The aluminum-plastic machine in the present invention comprises the polyvinyl chloride feeding device, so it has all the advantages of the polyvinyl chloride feeding device.

[0027] 11. In the present invention, when the PVC core needs to be replaced, the remaining PVC tape can be folded in half and placed on the residual tape carrier roller. During this process, the PVC tape is gently folded together, without creating creases. The folded PVC tape is then placed in a receiving container to prevent it from falling to the ground. This method effectively stores the PVC tape and prevents it from becoming entangled.

[0028] Furthermore, the brake mechanism of the present invention can compress and secure the PVC tape when the PVC core needs to be replaced, preventing the tape from shifting. This brake mechanism relaxes the compressive force of the second elastic pressure strip to a certain extent, thereby ensuring that the PVC tape can pass through the second elastic pressure strip and enter the aluminum-plastic packaging machine. This method effectively enables the replacement of the PVC core without stopping the machine, while also resolving the problem of the PVC tape easily shifting during the material roller replacement process.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] Example 1 This embodiment provides a polyvinyl chloride feeding device for an aluminum plastic machine, such as Figure 1 As shown, it includes: The material receiving shaft 1 is used to carry the polyvinyl chloride core 2. The polyvinyl chloride core 2 is driven to rotate and is arranged on the material receiving shaft 1 to feed the aluminum-plastic packaging machine; A carrying platform 3, used for carrying a polyvinyl chloride tape 4; A feed turning roller 12 is provided between the material receiving shaft 1 and the carrying platform 3 and is used to transfer the polyvinyl chloride tape 4 to the brake mechanism 5 of the carrying platform 3; a discharging turning roller 13, disposed between the carrying platform 3 and the residual material carrying roller 10, for moving the polyvinyl chloride tape 4 out of the brake mechanism 5; The brake mechanism 5 is provided on the supporting platform 3 and is driven to be connected to the polyvinyl chloride tape 4 output by the material receiving shaft 1, and is used to provide a dragging force to the polyvinyl chloride tape 4. In this embodiment, the brake mechanism 5 applies a dragging force to the polyvinyl chloride tape 4 during the operation of the aluminum-plastic packaging machine and during the replacement of the polyvinyl chloride core 2 by the polyvinyl chloride feeding device. Moreover, the dragging force applied by the brake mechanism 5 to the polyvinyl chloride tape 4 during the feeding process of the polyvinyl chloride feeding device is smaller than the dragging force applied by the brake mechanism 5 to the polyvinyl chloride tape 4 during the replacement of the polyvinyl chloride core 2 by the polyvinyl chloride feeding device. This ensures that the polyvinyl chloride tape 4 can move forward normally during the operation of the aluminum-plastic packaging machine, and at the same time keeps the polyvinyl chloride tape 4 taut to prevent the polyvinyl chloride tape 4 from being offset in position during the normal operation of the aluminum-plastic packaging machine; The residual material carrying roller 10, such as Figure 3As shown, the above-mentioned residual material carrying roller 10 is arranged in the discharge direction of the supporting platform 3, and is used to carry the remaining polyvinyl chloride tape 4 on the polyvinyl chloride core 2; the polyvinyl chloride tape 4 is folded in half and overlapped on the above-mentioned residual material carrying roller 10 to continuously feed the aluminum-plastic packaging machine; in this embodiment, when the operator needs to replace the polyvinyl chloride core 2, the remaining polyvinyl chloride tape 4 on the polyvinyl chloride core 2 to be replaced can be pulled out to form a folded polyvinyl chloride tape 4, and overlapped on the above-mentioned residual material carrying roller 10. The remaining polyvinyl chloride tape 4 is then carried by the residual material carrying roller 10. The length of the above-mentioned polyvinyl chloride tape 4 in the folded state carried on the residual material carrying roller 10 is effectively shortened by half, which is easier to store and less likely to cause the problem of mutual entanglement. At the same time, the above-mentioned residual material carrying roller 10 allows the polyvinyl chloride tape 4 to be regularly bent and overlapped for storage, effectively preventing the polyvinyl chloride tape 4 from sticking together; The material receiving container 11 is provided corresponding to the residual material carrying roller 10 and is used to accommodate the polyvinyl chloride tape 4 overlapped on the residual material carrying roller 10 .

[0034] In this embodiment, if Figures 1 to 3 As shown, the braking mechanism 5 comprises two groups, each comprising a first elastic strip 6 and a second elastic strip 7, arranged along the width of the PVC strip 4. The first and second elastic strips 6 and 7 are made of silicone and are horizontally arranged at both ends of the support platform 3, along the width of the PVC strip 4. The first and second elastic strips 6 and 7 are driven to move toward the support platform 3 to compress the PVC strip 4. Furthermore, a feeding gap is provided between the first and second elastic strips 6 and 7 and the support platform 3, allowing the PVC strip 4 to pass through.

[0035] The brake mechanism 5 also includes adjustment components 9 for respectively adjusting the drag force of the first elastic pressure strip 6 and the second elastic pressure strip 7 toward the support platform 3. These adjustment components 9 are used to drive the first elastic pressure strip 6 or the second elastic pressure strip 7 toward the support platform 3. In this embodiment, the two adjustment components 9 corresponding to the first elastic pressure strip 6 and the second elastic pressure strip 7, respectively, can quickly and accurately adjust the pressure applied by the pressure strips to the polyvinyl chloride tape 4. The operator can adjust the drag force of the brake mechanism 5 using these adjustment components 9 as needed.

[0036] In this embodiment, if Figure 3As shown, a feed roller 8 is provided between the first elastic strip 6 and the second elastic strip 7 to guide the PVC strip 4 into the second elastic strip 7. The feed roller 8 is positioned adjacent to the second elastic strip 7 and is driven to rotate to transfer the PVC strip 4 to the brake mechanism 5. The feed roller 8 effectively guides the PVC strip 4 into the brake mechanism 5, located near the discharge turning roller 13. The second elastic strip 7 applies a compressive force to the PVC strip 4 within the brake mechanism, thereby dragging the PVC strip 4. Furthermore, the feed roller 8 also flattens the PVC strip 4, preventing it from sticking.

[0037] In this embodiment, if Figure 3 As shown, the feed turning roller 12 and the discharge turning roller 13 are respectively provided with an anti-deviating collar 14 for limiting the position of the polyvinyl chloride belt 4. The anti-deviating collar 14 can effectively limit the position of the polyvinyl chloride belt 4 and avoid the problem of position deviation of the polyvinyl chloride belt 4.

[0038] In this embodiment, if Figure 2 As shown, the carrier 3 is provided with a cutting groove 15 for accommodating a cutter to allow an operator to cut the polyvinyl chloride tape 4. By providing the cutting groove 15 on the carrier 3, it is effectively convenient for the operator to cut the polyvinyl chloride tape 4 overlapped on the carrier 3.

[0039] How to use the PVC feeding equipment of aluminum plastic machine, such as Figures 1 to 3 As shown, the following steps are included: Step S1, when the remaining amount of the polyvinyl chloride core 2 on the material receiving shaft 1 is insufficient, the aluminum-plastic packaging machine is not stopped and the polyvinyl chloride tape 4 on the supporting platform 3 is dragged to pull out the remaining polyvinyl chloride tape 4 on the polyvinyl chloride core 2 to form a folded polyvinyl chloride tape 4, which is overlapped on the residual material carrying roller 10, and then the folded polyvinyl chloride tape 4 is transferred to the material receiving container 11; the aluminum-plastic packaging machine is continuously fed by the folded polyvinyl chloride tape 4 in the material receiving container 11; Step S2, cutting the polyvinyl chloride tape 4 at the root of the polyvinyl chloride core 2 that needs to be replaced; Step S3: without stopping the aluminum-plastic packaging machine, replace the polyvinyl chloride core 2 on the material receiving shaft 1, and wind the polyvinyl chloride tape 4 on the polyvinyl chloride core 2 onto the feed turning roller 12; Step S4, controlling the brake mechanism 5 to press and fix the polyvinyl chloride tape 4, and ensuring that the pressure of the brake mechanism 5 on the side close to the discharge turning roller 13 does not prevent the polyvinyl chloride tape 4 from normally entering the discharge turning roller 13; Splice the newly replaced polyvinyl chloride tape 4 and the original polyvinyl chloride tape 4 together; Step S5, controlling the brake mechanism 5 to release the clamping fixation, and driving the material receiving shaft 1 to flip, winding the polyvinyl chloride tape 4 in the material receiving container 11 onto the material receiving shaft 1, and completing the polyvinyl chloride feeding work without stopping the aluminum-plastic packaging machine.

[0040] In this embodiment, in the above step S4, the specific steps of controlling the brake mechanism 5 to press and fix the polyvinyl chloride belt 4 are as follows: The first elastic bead 6 is adjusted by the adjusting component 9 so that the first elastic bead 6 completely compresses the polyvinyl chloride tape 4 at the end of the supporting platform 3 near the infeed turning roller 12. At the same time, the second elastic bead 7 is adjusted by the adjusting component 9 so that the second elastic bead 7 appropriately compresses the polyvinyl chloride tape 4 at the end of the supporting platform 3 near the outfeed turning roller 13, so that the pressure of the second elastic bead 7 does not prevent the polyvinyl chloride tape 4 from normally entering the outfeed turning roller 13.

[0041] In this embodiment, in the above step S4, the specific steps of splicing the newly replaced polyvinyl chloride tape 4 and the original polyvinyl chloride tape 4 together are as follows: Overlapping the newly replaced polyvinyl chloride tape 4 with the original polyvinyl chloride tape 4, and pressing and fixing the polyvinyl chloride tape 4 on the supporting platform 3 by the brake mechanism 5; cutting the overlapping portion of the newly replaced polyvinyl chloride tape 4 and the original polyvinyl chloride tape 4 and discarding the cut polyvinyl chloride tape 4; The newly replaced polyvinyl chloride belt 4 and the original polyvinyl chloride belt 4 are connected together by adhesive tape.

[0042] Of course, this embodiment does not specifically limit whether the polyvinyl chloride feeding equipment includes the discharge turning roller 13. In other embodiments, the polyvinyl chloride belt 4 removed from the brake mechanism 5 directly enters the next workstation without changing the conveying direction through the discharge turning roller 13.

[0043] Of course, this embodiment does not specifically limit whether the brake mechanism 5 works during the operation of the aluminum-plastic packaging machine. In other embodiments, the brake mechanism 5 does not provide a drag force toward the polyvinyl chloride tape 4 during the operation of the aluminum-plastic packaging machine.

[0044] Of course, this embodiment does not specifically limit the specific structure of the brake mechanism 5. In other embodiments, the brake mechanism 5 can also be a pressure block or a limiting pressure plate, etc., through which the pressing force is applied to the polyvinyl chloride belt 4.

[0045] Of course, this embodiment does not specifically limit the specific materials of the first elastic strip 6 and the second elastic strip 7. In other embodiments, the first elastic strip 6 and the second elastic strip 7 can also be made of other flexible materials.

[0046] Example 2 An aluminum-plastic machine comprises: polyvinyl chloride feeding equipment and an aluminum-plastic packaging machine.

[0047] PVC feeding equipment, such as Figure 1 As shown, it includes: The material receiving shaft 1 is used to carry the polyvinyl chloride core 2. The polyvinyl chloride core 2 is driven to rotate and is arranged on the material receiving shaft 1 to feed the aluminum-plastic packaging machine; A carrying platform 3, used for carrying a polyvinyl chloride tape 4; A feed turning roller 12 is provided between the material receiving shaft 1 and the carrying platform 3 and is used to transfer the polyvinyl chloride tape 4 to the brake mechanism 5 of the carrying platform 3; a discharging turning roller 13, disposed between the carrying platform 3 and the residual material carrying roller 10, for moving the polyvinyl chloride tape 4 out of the brake mechanism 5; The brake mechanism 5 is provided on the supporting platform 3 and is driven to be connected to the polyvinyl chloride tape 4 output by the material receiving shaft 1, and is used to provide a dragging force to the polyvinyl chloride tape 4. In this embodiment, the brake mechanism 5 applies a dragging force to the polyvinyl chloride tape 4 during the operation of the aluminum-plastic packaging machine and during the replacement of the polyvinyl chloride core 2 by the polyvinyl chloride feeding device. Moreover, the dragging force applied by the brake mechanism 5 to the polyvinyl chloride tape 4 during the feeding process of the polyvinyl chloride feeding device is smaller than the dragging force applied by the brake mechanism 5 to the polyvinyl chloride tape 4 during the replacement of the polyvinyl chloride core 2 by the polyvinyl chloride feeding device. This ensures that the polyvinyl chloride tape 4 can move forward normally during the operation of the aluminum-plastic packaging machine, and at the same time keeps the polyvinyl chloride tape 4 taut to prevent the polyvinyl chloride tape 4 from being offset in position during the normal operation of the aluminum-plastic packaging machine; The residual material carrying roller 10, such as Figure 3As shown, the above-mentioned residual material carrying roller 10 is arranged in the discharge direction of the supporting platform 3, and is used to carry the remaining polyvinyl chloride tape 4 on the polyvinyl chloride core 2; the polyvinyl chloride tape 4 is folded in half and overlapped on the above-mentioned residual material carrying roller 10 to continuously feed the aluminum-plastic packaging machine; in this embodiment, when the operator needs to replace the polyvinyl chloride core 2, the remaining polyvinyl chloride tape 4 on the polyvinyl chloride core 2 to be replaced can be pulled out to form a folded polyvinyl chloride tape 4, and overlapped on the above-mentioned residual material carrying roller 10. The remaining polyvinyl chloride tape 4 is then carried by the residual material carrying roller 10. The length of the above-mentioned polyvinyl chloride tape 4 in the folded state carried on the residual material carrying roller 10 is effectively shortened by half, which is easier to store and less likely to cause the problem of mutual entanglement. At the same time, the above-mentioned residual material carrying roller 10 allows the polyvinyl chloride tape 4 to be regularly bent and overlapped for storage, effectively preventing the polyvinyl chloride tape 4 from sticking together; The material receiving container 11 is provided corresponding to the residual material carrying roller 10 and is used to accommodate the polyvinyl chloride tape 4 overlapped on the residual material carrying roller 10 .

[0048] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
