Abstract
Description
Technical Field
[0001] This utility model relates to the field of winding machine technology, and more specifically, to an automatic feeding device for PET plastic steel strapping. Background Technology
[0002] PET strapping uses polyethylene terephthalate (PET) as its core raw material and is forged through processes such as extrusion and stretching. It perfectly combines the toughness of steel strapping with the flexibility of plastic strapping, making it an ideal choice for bundling goods in industries such as building materials, paper, and steel. The winding machine, as a crucial part of the strapping production process, uses a rotating reel to neatly wind up the continuously produced strapping, transforming it into standard rolls that are easy to store, transport, and use.
[0003] The feeding device in the winding machine is the key to ensuring stable conveying and high-quality winding of the strapping. Through the coordinated operation of multiple traction rollers, it precisely and smoothly transports the strapping from the production stage to the winding area. These traction rollers are like the "conveyor belt" on the production line; their coordination precision directly affects the conveying effect of the strapping and the final winding quality.
[0004] However, current traction rollers generally suffer from the drawback of non-adjustable positions, a defect that introduces numerous hidden dangers into production. Because the roller spacing and pressure cannot be flexibly adjusted according to differences in strapping thickness and material, slippage, deviation, and even breakage are highly likely during transport, severely hindering production efficiency and damaging product quality. Simultaneously, the non-adjustable rollers make precise tension control difficult, leading to inconsistent winding tightness and problems such as coil collapse and unwinding, reducing the aesthetics and practicality of the finished product. Furthermore, the fixed roller setup is inflexible in adapting to the production needs of different strapping specifications, greatly limiting the equipment's versatility and forcing companies to invest more in specialized equipment, increasing their operational burden.

[0027] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0028] Example
[0029] Please refer to Figures 1-7 This application provides an automatic feeding device for PET plastic steel strapping, including: a processing platform 1, one end of which is a feeding end and the other end is a discharging end, and a guide groove 5 is provided along the direction from the feeding end to the discharging end; a position adjustment structure, including a guide member, a guide rail 4 and a sliding part 14, wherein the guide member is slidably engaged with the guide groove 5 and can rotate in the guide groove 5, the guide rail 4 is connected to the guide member and is perpendicular to the guide groove 5, the sliding part 14 is slidably disposed on the guide rail 4, and a traction roller 2 is disposed on the sliding part 14 and is perpendicular to both the guide rail 4 and the guide groove 5; wherein the number of traction units formed by the position adjustment structure and the traction roller 2 is multiple.
[0030] The automatic feeding device for PET plastic strapping disclosed in this application achieves initial horizontal or vertical positioning of the traction roller 2 through the sliding rotational cooperation of the guide groove 5 of the processing platform 1 and the guide component of the position adjustment structure. Based on this, the sliding adjustment mechanism composed of the guide rail 4 and the sliding part 14 further achieves more precise positioning of the traction roller 2 in the conveying direction. Multiple traction units work collaboratively, enabling rapid adjustment of roller spacing, pressure, and tension parameters according to the thickness, material, and specifications of the strapping. This device fundamentally solves the problems of slippage, deviation, and uneven winding caused by traditional fixed rollers, significantly improving the stability of strapping conveying and the quality of the finished winding product. Simultaneously, through flexible parameter adjustment, it enhances the equipment's compatibility with different product specifications, avoiding the need for companies to repeatedly purchase specialized equipment, and achieving simultaneous improvement in production efficiency and equipment versatility.
[0031] Understandably, the sliding and rotating design of the guide component enables the horizontal and vertical adjustment of the position of the guide rail 4. Combined with the design of the sliding part 14, this makes the adjustment flexibility of the traction roller 2 even greater.
[0032] In a preferred embodiment, the bottom of the guide groove 5 extends through to the outer side wall of the processing platform 1.
[0033] The aforementioned guide component includes a guide shaft 9 that passes through the aforementioned guide groove 5. A limiting piece 10 is provided at one end of the guide shaft 9 away from the aforementioned guide rail 4. The limiting piece 10 and the aforementioned guide rail 4 are respectively located on both sides of the aforementioned guide groove 5. The limiting piece 10 is provided with a locking bolt for locking with the aforementioned processing platform 1.
[0034] In the above embodiment, the guide shaft 9 can rotate in the guide groove 5. The limiting plate 10 and the guide rail 4 clamp and position the guide shaft 9, preventing it from sliding along the axial direction. The locking bolts provided on the limiting plate 10 can form a reliable locking fit with the processing platform 1 after the guide is adjusted to the appropriate position, ensuring that the guide and traction roller 2 remain stable during operation and preventing positional deviation due to vibration or other factors. This ensures both the flexibility of adjusting the traction roller 2 and enhances the structural stability of the entire feeding device during operation.
[0035] Optionally, the number of the locking bolts is four, and they are evenly spaced along the circumferential direction of the limiting piece 10.
[0036] In a preferred embodiment, the guide rail 4 includes a connecting plate. A sliding groove is provided on the side of the connecting plate away from the limiting piece 10. A sliding block 11 is slidably fitted in the sliding groove. A threaded post 13 is provided in the sliding block 11. The threaded post 13 passes through the opening of the sliding groove and is threadedly fitted with a locking nut 12.
[0037] The sliding part 14 is provided on the threaded post 13 outside the sliding groove.
[0038] In the above embodiment, the sliding block 11 can slide freely within the sliding groove. Combined with the threaded post 13 and the locking nut 12, operators can quickly adjust the position of the traction roller 2 according to actual needs and fix it by tightening the nut, ensuring that the roller spacing and pressure can be flexibly adapted when producing strapping of different specifications. This structure not only ensures the stability of the traction roller 2 during operation, avoiding positional deviation due to vibration and other factors, but also enables efficient production adaptation to strapping of different thicknesses and materials through simple thread tightening operations, effectively improving the practicality and versatility of the feeding device.
[0039] It is understandable that the cross-sections of the sliding groove and the sliding part 14 are both T-shaped to prevent the sliding part 14 from falling out of the sliding groove.
[0040] In a preferred embodiment, a toggle piece 8 is provided at the end of the guide shaft 9 away from the traction roller 2.
[0041] In the above embodiment, the operator can quickly adjust the position of the guide shaft 9 within the guide groove 5 by directly actuating this component, thereby achieving preliminary horizontal or vertical positioning of the traction roller 2. Compared to a structure without the actuating piece 8, this design eliminates the need for additional tools, simplifies the adjustment process, and improves operational efficiency.
[0042] In a preferred embodiment, the feed end of the processing platform 1 is provided with parallel and spaced feed guide rollers 3.
[0043] In the above embodiment, the feeding end of the processing platform 1 is provided with parallel and spaced feeding guide rollers 3, which can provide precise guidance and stable support for the PET plastic steel strapping entering the feeding device.
[0044] In a preferred embodiment, the discharge end of the processing platform 1 is rotatably equipped with a roller 7, and the roller 7 is connected to a power structure 6.
[0045] In the above embodiment, the rotating roller 7, which is rotatably mounted at the discharge end of the processing platform 1, is connected to the power structure 6, providing a stable and continuous driving force for the winding process of PET plastic steel strapping. The rotatable design of the roller 7 ensures that it can smoothly wind up the strapping under the action of power, realizing the conversion of the strapping from linear conveying to regular winding; while the configuration of the power structure 6 can flexibly adjust the winding speed and tension according to the winding requirements of different specifications of strapping, avoiding problems such as collapse and unwinding.
[0046] In a preferred embodiment, the aforementioned power structure 6 includes a drive motor and a gearbox that are coupled together.
[0047] In the above embodiment, the power structure 6 adopts a design that combines a drive motor and a gearbox, enabling precise control of power output during the strapping winding process. The drive motor provides a stable power source, while the gearbox can flexibly adjust the transmission ratio according to the winding requirements of different strapping specifications, thereby changing the speed and torque of the winding roller 7. Through their coordinated operation, it is possible to ensure that the winding speed matches the production rhythm and to precisely control the winding tension, effectively avoiding problems such as collapse and unwinding caused by excessive speed or uneven tension, thus improving the quality of the finished strapping.
