Description
Technical Field
[0001] This utility model relates to the technical field of packing tape winding equipment, specifically a winding mechanism for a packing tape production line. Background Technology
[0002] In the production process of a strapping production line, the winding process is the core step in winding continuously formed strapping into regular rolls. Its performance directly affects the production efficiency, roll quality, and automation level of the production line. With the continuous expansion of strapping applications (such as logistics packaging and industrial bundling), the market has placed higher demands on the diversity of strapping specifications (such as differences in width, thickness, and length) and roll quality (such as winding tightness and end-face flatness). Traditional winding mechanisms are gradually showing the following limitations:
[0003] Low efficiency in winding drum installation and disassembly: Traditional winding mechanisms have fixed drum fixing frames, and the installation of the winding drum requires manual handling and alignment with the mounting holes. Disassembly requires the removal of multiple fasteners, which is cumbersome and time-consuming. In particular, when changing production specifications, frequent drum changes will significantly reduce the efficiency of the production line.
[0004] Insufficient flexibility in height adjustment: In order to adapt to the installation requirements of different specifications of winding drums (such as large-diameter windings requiring a lower installation height to avoid interference, and small-diameter windings requiring a higher height to match subsequent processes), some winding mechanisms are designed with lifting functions, but most of them use manual hoists or simple screw structures. The adjustment process requires manual intervention, the accuracy is difficult to guarantee, and there are safety hazards.
[0005] Poor winding stability: During the winding process, the winding drum needs to withstand the continuous tension and rotational torque of the packing strap. If the fixing structure is not designed properly (such as fixing only through single-point contact), the winding drum is prone to shift due to uneven force, resulting in loose winding, tilted end face and other problems, which seriously affect product quality.
[0006] Weak automation integration capability: The drive and transmission systems of traditional winding mechanisms are mostly independently designed, with poor linkage with the production line control system (such as tension control and speed synchronization), making it difficult to achieve intelligent adjustment of the winding process (such as automatically adjusting the speed according to the tension of the packing tape), which limits the process of upgrading the production line to automation and intelligence.
[0007] Therefore, there is an urgent need for a winding mechanism that is compact, easy to operate, highly stable, and compatible with production line automation systems to address the shortcomings of traditional technologies in terms of installation efficiency, height adjustment, winding stability, and automation integration. Utility Model Content
[0008] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a winding mechanism that is easy to install, has precise height adjustment, and provides stable winding.
[0009] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a winding mechanism for a strapping production line, including a lifting device and a roll fixing frame. The roll fixing frame is fixedly connected to one side of the lifting device. The height of the roll fixing frame can be adjusted by the lifting device to facilitate the installation or disassembly of the winding drum. A winding drum is fixedly installed on the roll fixing frame. The roll fixing frame includes a rotating disk, a support rod, a connecting rod, a sliding frame, a rotating shaft, and a handwheel. One side of the rotating disk is fixedly connected to the lifting device, and the other side of the rotating disk is fixedly connected to a central platform. A support rod is embedded in the center of the rotating disk and the central platform. Several sliding cavities are respectively opened on the central axis of the support rod. A sliding frame is slidably connected in each sliding cavity. A rotating shaft is rotatably connected to the center of the support rod. Each rotating shaft located in one of the sliding cavities is provided with threads. The sliding frames are respectively connected to the rotating shaft via threads. One end of the rotating shaft passes through the support rod and is fixedly connected to the handwheel. The outer wall has several storage slots along the axis. The storage slots on the support rod are evenly arranged in a ring. A support rod is embedded in the storage slot. Two sets of connecting rods are rotatably connected to both ends of the support rod. The two sets of connecting rods are rotatably connected to the sliding frame on the adjacent side. Sliding holes are opened between the two ends of the storage slot and the sliding cavity. The connecting rods are movably connected in the sliding holes. An installation hole is provided in the middle of the winding drum. Several fixed pin holes are opened on both sides of the winding drum centered on the installation hole. The winding drum installation operation is as follows: First, the height of the winding drum fixing frame is lowered by the lifting device. Then, the support rod is inserted into the installation hole through the installation hole. In addition, the limiting pins are inserted into the fixed pin holes. Next, the handwheel is turned. The handwheel drives the rotating shaft to rotate. The rotating shaft drives the sliding frame to move through the threads. The sliding frame drives the connecting rod to rotate. The connecting rod drives the support frame to move outward along the storage slot, so that the support frame abuts against the inner wall of the installation hole. The winding drum is relatively fixed by the support frame.
[0010] In the above technical solution, a number of limiting pins are fixedly connected to one side of the central platform, and the limiting pins are evenly arranged around the support rod.
[0011] In the above technical solution, the lifting device includes a mounting plate, a support frame, a sliding block, a threaded rod, a first motor, and a drive device. The support frame is fixedly connected to the upper end of the mounting plate. A sliding groove is provided inside the support frame, and a sliding block is slidably connected inside the sliding groove. Symmetrical threaded holes are provided on both sides of the sliding block, and threaded rods are threadedly connected to the threaded holes. One end of the threaded rod is rotatably connected to the inner wall of the sliding groove, and the other end of the threaded rod is connected to the first motor. The first motor is embedded in the support frame. A drive device is provided on one side of the sliding block, and the drive device is fixedly connected to the rotating disk.
[0012] In the above technical solution, the driving device includes a sliding sleeve, a rotating sleeve, an outer cover, a transmission gear, a drive gear, a second motor, and a first bearing. The sliding sleeve is fixedly connected to one side of the sliding block, and the rotating sleeve is rotatably connected to the sliding sleeve. The outer cover is fixedly connected to one end of the rotating sleeve, and the first bearing is fixedly connected to the inner wall of the outer cover. The middle part of the first bearing is fixedly connected to the sliding sleeve. The transmission gear is fixedly connected to the other end of the rotating sleeve, and the drive gear is meshed with the drive gear. The drive gear is fixedly connected to the second motor, and the second motor is fixedly connected to the upper end of the sliding block. One side of the rotating disk is fixedly connected to the outer cover.
[0013] In the above technical solution, a rotating shaft is rotatably connected inside the sliding sleeve tube. One end of the rotating shaft passes through the sliding sleeve tube and is fixedly connected to the inner wall of the outer casing. A rotating shaft hole is opened in the sliding block on one side of the sliding sleeve tube. The other end of the rotating shaft is rotatably connected in the rotating shaft hole. An installation groove is opened on the sliding block on one side of the rotating shaft hole. A second bearing is fixedly connected in the installation groove. One end of the rotating shaft is fixedly connected in the second bearing.
[0014] The beneficial effects of this utility model are:
[0015] 1. Highly efficient installation and disassembly of the winding drum, adaptable to rapid changeover needs: Traditional mechanisms require manual alignment and tightening due to the fixed structure, which is time-consuming when changing drums; This utility model uses a lifting device to reduce the height of the drum fixing frame, and with the insertion of the support rod and the winding drum mounting hole, and the quick pre-positioning of the limit pin and the fixed pin hole, the radial fixing of the support frame to the winding drum can be completed by simply turning the handwheel, simplifying the installation / disassembly steps and greatly improving the switching efficiency of multi-specification winding drums.
[0016] 2. Precise and flexible height adjustment to suit different roll diameter requirements: Traditional mechanisms rely on manual adjustment or simple lead screws, resulting in low precision; This utility model adopts a double threaded rod synchronous drive sliding block design, with the lifting and lowering controlled by the first motor, ensuring smooth operation. It can be precisely adjusted according to the target roll diameter of the winding drum (lowering the height to prevent interference for large roll diameters and raising it to match subsequent processes for small roll diameters), without the need for manual intervention, significantly enhancing adaptability.
[0017] 3. Strong winding stability, ensuring consistent package quality: Traditional mechanisms are prone to winding cylinder displacement and loose package due to single-point fixing; This utility model uses a linkage structure of rotating shaft rod-sliding frame-connecting rod to drive the support frame to unfold outward along the storage groove, making multiple points of contact with the inner wall of the winding cylinder mounting hole, and with the radial limit pin, the winding cylinder is double-fixed to avoid winding displacement and tilting.
[0018] 4. The drive system has strong integration and supports intelligent control: Traditional mechanisms have poor linkage with the production line and are difficult to adjust in real time; the drive device of this utility model drives the roll fixing frame to rotate through the second motor-drive gear-transmission gear-rotating sleeve transmission chain, which can be directly integrated with the tension sensor and PLC system of the production line. The speed can be adjusted in real time according to the tension of the packing tape to meet the needs of high-speed winding and variable tension, and help the intelligent upgrade of the production line.
