[0024] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0025] Example

[0026] Please refer to Figures 1-4 This application provides a guiding assembly for a feeding device in a PET strapping production line, comprising: a support base 1, the top side of which is used for the directional conveying of the PET strapping; an active guiding unit, including a first mounting plate 3, a positioning shaft 13, an annular cylinder 12, an annular adjusting plate 17, an electric telescopic rod 4, and a power structure. The number of the first mounting plates 3 is two, both of which are disposed on the top side of the support base 1 and spaced apart along a direction perpendicular to the conveying direction of the PET strapping. The positioning shaft 13 is disposed between the two first mounting plates 3, and both ends are connected to the two first mounting plates 3 respectively. The annular cylinder 12 is rotatably sleeved on the positioning shaft 13. The power structure is used to drive the annular cylinder 12 to rotate; wherein, there are two annular adjusting plates 17, both of which are movably sleeved on the outside of the annular cylinder 12, and each of the annular adjusting plates 17 is provided with the electric telescopic rod 4, which is used to drive the annular adjusting plate 17 to slide back and forth along the axial direction of the annular cylinder 12; and an auxiliary guiding unit, including a rotating shaft 6 and two second mounting plates 5, both of which are provided on the top side of the support base 1 and are spaced apart along the conveying direction perpendicular to the PET strapping, the rotating shaft 6 is rotatably disposed between the two second mounting plates 5, and both ends are rotatably engaged with the two second mounting plates 5 respectively.

[0027] In the guiding assembly of this application, the support base 1 provides a conveying foundation for the PET strapping. The active guiding unit drives the annular cylinder 12 to rotate via a power structure, generating an active conveying force for the strapping. Simultaneously, the electric telescopic rod 4 drives the annular adjusting plate 17 to slide along the axis of the annular cylinder 12. The spacing between the two annular adjusting plates 17 can be adjusted according to the width of the strapping, achieving width adaptation and active guidance. The rotating shaft 6 of the auxiliary guiding unit further limits and guides the strapping through rotation. Its advantages are that the electric telescopic rod 4 directly drives the annular adjusting plate 17 to adjust the spacing, simplifying the adjustment structure, and the rotating annular cylinder 12 of the active guiding unit can provide active conveying force, which, together with the auxiliary guiding unit, improves the guiding effect.

[0028] In a preferred embodiment, the number of the above-mentioned active guiding units is two, and they are spaced apart along the conveying direction of the PET strapping.

[0029] In the above embodiment, two active guiding units are set at intervals along the conveying direction of the PET strapping, allowing the strapping to pass through two active guiding points sequentially on the conveying path. The first active guiding unit performs initial correction and conveying of the strapping, while the second active guiding unit further corrects any possible deviations. Through this dual active guiding action, the control stability of the strapping's conveying trajectory is enhanced, reducing swaying or deviation during conveying. Simultaneously, the coordinated conveying of the two units can more evenly distribute the guiding force on the strapping, reducing the load on a single guiding point and improving the overall guiding effect and equipment durability.

[0030] In a preferred embodiment, the number of the above-mentioned auxiliary guiding units is two, and they are spaced apart along the conveying direction of the PET strapping.

[0031] Both of the aforementioned auxiliary guidance units are positioned between the two aforementioned active guidance units.

[0032] In the above embodiment, two auxiliary guiding units are spaced apart between two active guiding units along the conveying direction of the PET strapping. This adds two auxiliary limiting points to the conveying path formed by the active guiding units. The strapping conveyed by the previous active guiding unit is initially stabilized by the first auxiliary guiding unit, then its attitude is further calibrated by the second auxiliary guiding unit before entering the next active guiding unit. This ensures that the strapping maintains a stable trajectory even during the gaps in active conveying, reducing conveying fluctuations caused by the intervals between active guiding units. Through the continuous coordination of "active conveying - auxiliary stabilization - active conveying," the overall guiding consistency and accuracy are improved, and the risk of deviation is reduced.

[0033] In a preferred embodiment, the horizontal height of the aforementioned rotating shaft 6 is higher than the horizontal height of the aforementioned annular cylinder 12.

[0034] In the above embodiment, the horizontal height of the rotating shaft 6 is set higher than that of the annular cylinder 12, so that when the PET strapping contacts the rotating shaft 6 of the auxiliary guide unit during conveying, it is slightly lifted upwards, forming staggered contact points with the annular cylinder 12 of the active guide unit. This height difference allows the strapping to maintain a certain tension during conveying, reducing wrinkles or deviations caused by slack. At the same time, the height difference applies guiding constraints to the strapping from different angles, further limiting its vertical sway, enhancing the overall guiding stability, and ensuring a more accurate conveying trajectory.

[0035] In a preferred embodiment, the power structure includes: a drive shaft 11, which is coaxially connected to one end of the annular cylinder 12; and a drive motor 18, which is connected to the drive shaft 11 via a gear set 10.

[0036] In the above embodiments, the gear set 10 transmission has the characteristics of high transmission efficiency and large transmission torque, which can stably transmit the power of the drive motor 18 to the transmission shaft 11, thereby driving the annular cylinder 12 to rotate to provide a continuous and stable active conveying force; at the same time, the coaxial connection of the transmission shaft 11 ensures that the annular cylinder 12 is subjected to uniform force and has good rotational stability.

[0037] In a preferred embodiment, the end of the drive shaft 11 away from the annular cylinder 12 extends through to the outer side wall of the first mounting plate 3 and connects the drive motor 18 and the gear set 10; wherein the drive motor 18 and the gear set 10 are together fitted with a protective housing 2.

[0038] In the above embodiments, the protective box 2 can provide physical protection for the drive motor 18 and the gear set 10, preventing dust, debris and other impurities in the production environment from entering, reducing component wear, and reducing the impact of external collisions on the transmission structure, thereby improving the working stability and service life of the power structure.

[0039] In a preferred embodiment, the outer side wall of the annular cylinder 12 is provided with a guide groove 14, and the annular adjusting plate 17 is provided with a guide slider 16 adapted to the guide groove 14; wherein, the electric telescopic rod 4 is parallel to the axis of the annular cylinder 12, and the movable end is rotatably engaged with the annular adjusting plate 17, and the fixed end is fixedly connected to the first mounting plate 3.

[0040] In the above embodiment, the outer wall of the annular cylinder 12 is provided with an axial guide groove 14, the annular adjusting plate 17 is provided with a matching guide slider 16, and the electric telescopic rod 4 is parallel to the axis of the annular cylinder 12, the movable end is rotatably engaged with the annular adjusting plate 17, and the fixed end is fixed with the first mounting plate 3. Its advantage is that the cooperation between the guide groove 14 and the guide slider 16 can restrict the annular adjusting plate 17 to slide only along the axial direction of the annular cylinder 12, avoid deviation during adjustment, and ensure the width adjustment accuracy; the installation method of the electric telescopic rod 4 can stably output the driving force along the axial direction, and the rotatable engagement can reduce the mechanical stress during adjustment, improve the smoothness of the adjustment process and the structural stability.

[0041] In a preferred embodiment, the annular adjusting plate 17 is provided with an annular groove on its side circumferentially, and the movable end of the electric telescopic rod 4 is provided with a connecting block 15 adapted to the annular groove.

[0042] In the above embodiment, the annular adjusting plate 17 is provided with an annular groove on its side circumferentially, and the movable end of the electric telescopic rod 4 is provided with a matching connecting block 15. The advantage is that the connecting block 15 is embedded in the annular groove, which does not affect the rotation of the annular adjusting plate 17 with the annular cylinder 12, and ensures that the driving force of the electric telescopic rod 4 on the annular adjusting plate 17 is stably transmitted, avoiding the connection between the two from falling off during the adjustment process. At the same time, the cooperation between the annular groove and the connecting block 15 can limit the relative position between the movable end of the electric telescopic rod 4 and the annular adjusting plate 17, reduce the force offset during adjustment, and improve the reliability of width adjustment and the structural fit accuracy.

[0043] Optionally, both the connecting block 15 and the annular groove have T-shaped cross sections to prevent them from falling off when connected.

[0044] In a preferred embodiment, a dust collection structure is provided between the two auxiliary guide units; wherein, the dust collection structure includes two dust collection hoods 7, which are located above and below the auxiliary guide units respectively, and each of the dust collection hoods 7 is provided with a matching pump body 8 and a dust collection box 9.

[0045] In the above embodiment, a dust suction structure is provided between the two auxiliary guide units, and the dust suction hoods 7 are located above and below the auxiliary guide units respectively. Together with the pump body 8 and the dust collection box 9, the advantage is that the PET packing strap passing between the two auxiliary guide units can be suctioned in both directions, which can more thoroughly remove dust, debris and other impurities from the surface and surrounding area of ​​the packing strap, and reduce the impact of impurities on subsequent processing.
