Description

Technical Field

[0001] This utility model relates to the field of winding machines, and in particular to a core fixing device for a PVC film winding machine. Background Technology

[0002] The following points should be noted when installing the winding machine core: First, ensure that the core size matches the equipment to avoid operational malfunctions due to size mismatch. Second, check that the core surface is flat and undamaged to prevent scratching the material or affecting winding quality. Before installation, clean the contact surfaces of the core and equipment to ensure there are no impurities or oil stains to prevent slippage or misalignment. During installation, align the core with the center position to ensure concentricity between the core and the equipment, preventing shaking or eccentricity during operation. Tighten the bolts evenly to avoid deformation caused by overtightening on one side. Finally, manually test the machine after installation to confirm smooth operation without any abnormalities before putting it into production. Wear protective equipment during operation to ensure safety.

[0003] While existing technologies can achieve a certain level of core installation, they suffer from drawbacks: the cores are prone to skewing on one side during installation, resulting in uneven installation and potential axial damage. To address this, we propose a core fixing device for a PVC film winding machine, which solves the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a core fixing device for a PVC film winding machine.

[0005] The technical solution of this utility model: A core fixing device for a PVC film winding machine, comprising an mounting frame, a placement block, a connecting block one, and a connecting block two. The connecting block two is provided with the connecting block one at its upper end. Mounting frames are provided on both sides of the connecting block one and the connecting block two. A telescopic frame is inserted into the upper end of the mounting frame. A placement block is provided at the upper end of the telescopic frame. A lead screw is rotatably mounted on the lower end of the connecting block. A motor one is fixed at the upper end of the connecting block one. The lead screw is threadedly connected to the connecting block two. A gear one is provided at the lower end of the connecting block two.

[0006] When using this device, the core to be installed can be placed on the upper end of groove one, groove two, or groove three on the placement block. Then, the rear controller can drive motor two to rotate. Motor two can adjust the width between the mounting brackets by using gear one, gear two, and rack linkage to accommodate different core lengths. Motor one can drive the lead screw to rotate to adjust the height of connecting block one, facilitating the auxiliary installation and fixing of the corresponding core. This device can facilitate the auxiliary installation and positioning of cores and has high practicality.

[0007] Preferably, the mounting bracket is provided with a rack on the opposite side, and the rack meshes with a gear. The rack on the side of the mounting bracket meshes with a gear to ensure smooth transmission and accuracy during the width adjustment process, avoid slippage and deviation, improve adjustment accuracy, reduce mechanical wear, and extend equipment life.

[0008] Preferably, a retainer is fixed to the lower end of the second connecting block, and a rack is inserted into the retainer. The retainer fixes the rack in place, which further enhances the stability of the rack during movement, prevents vibration or dislocation of gear one, rack two and rack when they mesh, improves structural rigidity and ensures operational reliability.

[0009] Preferably, a gear two is rotatably mounted on the lower end of the connecting block two, and a fixing frame is fixed to the lower end of the connecting block two. The gear two is rotatably mounted inside the connecting block two, and a motor two is fixed to the lower end of the fixing frame. The output shaft of the motor two is fixedly connected to the rotation center of the lower end of the gear two. The direct linkage design between the gear two and the motor two, combined with the support of the fixing frame, optimizes the power transmission path, making width adjustment more efficient and energy consumption lower. This results in energy saving and high efficiency, simplifies the transmission structure, and reduces the failure rate.

[0010] Preferably, the mounting bracket has a base fixed at its lower end. The base is horizontally designed, which increases the support area, distributes the equipment load, ensures the overall structural balance and anti-overturning ability, enhances stability, and is suitable for high-load conditions.

[0011] Preferably, a telescopic rod is inserted into both sides of the connecting block, and the telescopic rod is fixedly connected to the opposite side of the telescopic frame. The telescopic rod connects the telescopic frame and the connecting block, providing synchronous support during height adjustment, preventing the placement block from tilting or shifting, maintaining the core in a horizontal position, and improving installation accuracy.

[0012] Preferably, telescopic rods are inserted into both sides of the connecting block two. The telescopic rods are fixedly connected to the opposite sides of the mounting frame on both sides. The telescopic rods fix the mounting frame and the connecting block two, maintaining the parallelism of the mounting frames on both sides during width adjustment, ensuring that the core is placed in the center, preventing off-center loading, and ensuring operational safety.

[0013] Preferably, the upper end of the placement block is provided with groove one, groove two and groove three in sequence, and the radius of groove one, groove two and groove three increases in sequence. The stepped design of the multi-radius grooves can be compatible with cores of different diameters, reduce the time for changing accessories, expand the scope of application and improve the ease of operation.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the coordinated design of the mounting frame, placement block, connecting block one, and connecting block two, combined with the height adjustment of the lead screw driven by motor one and the width adjustment of the mounting frame by motor two through gear and rack linkage, achieves rapid adaptation and precise positioning of cores of different sizes, significantly improving the efficiency and stability of core installation.

[0016] II. Based on the first beneficial effect, this device, through its modular structure and intelligent adjustment design, achieves high adaptability, ease of operation, and operational stability for core installation equipment. The combination of gear and rack transmission and motor drive ensures precise adjustment, while the multi-groove placement blocks and telescopic support structure further expand the equipment's functionality, significantly improving production efficiency and reducing the need for manual intervention. It is suitable for diverse industrial scenarios and has high practicality.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
