Description

Technical Field

[0001] This utility model belongs to the field of film winding equipment, and specifically relates to a film winding device. Background Technology

[0002] In various industrial sectors such as packaging, electronics, and printing, film winding is a crucial process for ensuring production continuity and standardized product storage. As a core piece of equipment, the structural design of the film winding device directly impacts production efficiency and the convenience of subsequent processes. Currently, widely used film winding devices in the industry generally employ the core working principle of a motor-driven mandrel rotation. These devices directly or indirectly connect the mandrel to the motor output shaft, utilizing the torque provided by the motor to drive the mandrel to rotate at high speed. This causes the film to gradually wind around the surface of the mandrel under tension, ultimately forming a neat roll of film.

[0003] However, the existing structure has a significant inherent defect: the fixed or linked connection between the core tube and the drive mechanism means that the core tube cannot be separated and removed after winding. This problem directly leads to a series of limitations: on the one hand, the wound film must be transported and stored as a whole along with the core tube, which not only increases the volume and weight of material transfer but also limits the subsequent flexible cutting, slitting, and other processing operations of the film; on the other hand, if the core tube is a reusable component, its inability to be removed makes it difficult to recycle, resulting in resource waste and increased production costs; at the same time, for production scenarios that require changing core tubes of different specifications, the existing structure requires the entire device to be disassembled and adjusted, which is cumbersome and seriously affects production efficiency.

[0004] With the increasing demands for process flexibility, resource utilization and production efficiency in industrial production, the limitations of existing film winding devices due to the inability to remove the core tube are becoming increasingly apparent. There is an urgent need for a winding device structure that can easily remove the core tube to address the shortcomings of existing technologies. Utility Model Content

[0027] Among them, there is a cylinder 1, a hollow structure 1a, a fastener 2, a first notch 2a, a threaded hole 2b, a winding rod 3, an outward protrusion 3a, a retaining ring 4, a second notch 4a, a geared motor 5, a connecting shaft 6, a sleeve part 6a, and a coupling 7. Detailed Implementation

[0028] like Figure 1-6 As shown, this embodiment includes a cylinder 1, a drive mechanism, a fixing member 2, and a winding rod 3.

[0029] The cylinder 1 is a cylindrical tube. To reduce weight, this embodiment has a hollow structure 1a on the side wall of the cylinder 1. Specifically, the hollow structure 1a uses oval holes that are arrayed and distributed in a ring along the length of the cylinder 1.

[0030] The output end of the drive mechanism is connected to one end of the cylinder 1, and the drive mechanism drives the cylinder 1 to rotate around its axis.

[0031] Preferably, in this embodiment, the drive mechanism adopts a geared motor 5, and is also provided with a connecting shaft 6 and a coupling 7. The output end of the geared motor 5 is connected to one end of the connecting shaft 6 through the coupling 7, and the other end of the connecting shaft 6 is connected to one end of the cylinder 1. The geared motor 5 drives the connecting shaft 6 to rotate, and the rotation of the connecting shaft 6 in turn drives the cylinder 1 to rotate.

[0032] Considering the inner diameter of the rolled film, the diameter of the cylinder 1 should not be too small. At the same time, considering the weight of the connecting shaft 6 and the driving force of the reduction motor 5, the diameter of the connecting shaft 6 should not be too large. Therefore, in this embodiment, a sleeve part 6a is provided at the other end of the connecting shaft 6. The sleeve part 6a can be fitted onto one end of the cylinder 1. The side wall of the sleeve part 6a is provided with a threaded hole, and the sleeve part 6a is provided with a corresponding through hole. The two are connected by bolt threads.

[0033] The fixing member 2 is fixed to the side wall of the cylinder 1 and to one end near the drive mechanism. In this embodiment, the fixing member 2 is configured as a sleeve and is directly sleeved on the cylinder 1. The inner side wall of the fixing member 2 that fits against the cylinder 1 is provided with a first notch 2a.

[0034] The first notch 2a has two openings, which are symmetrically arranged with the axis of the cylinder 1 as the center line.

[0035] In yet another embodiment, the fixing member 2 may also adopt a block structure, and correspondingly, two second notches 4a are provided with two fixing members 2.

[0036] In this embodiment, the winding rod 3 is arranged parallel to the cylinder 1, and one end of the winding rod 3 is inserted into the first notch 2a. In order to fix the winding rod 3 and prevent it from loosening, in this embodiment, a threaded hole 2b communicating with and perpendicular to the first notch 2a is further provided on the side wall of the fixing member 2, and a jackscrew is inserted into the threaded hole 2b to tightly press the winding rod 3, so that the winding rod 3 can be fixed on the cylinder 1.

[0037] In this embodiment, the winding rod 3 adopts a U-shaped structure, and the two ends of the open end of the U-shape are just inserted into the two first notches 2a. Further, both sides of the closed end of the U-shape of the winding rod 3 protrude outward to form outward protruding portions 3a, and the outward protruding portions 3a and the two parallel horizontal sections form a "convex" shape.

[0038] In this embodiment, the first notch 2a is provided to make the winding rod 3 close to the cylinder 1, so that at the beginning of winding, the end of the film will not escape from the clamping of the two. However, if the two are attached too tightly, it will easily lead to the situation that the end of the film is not easy to insert. Therefore, the winding rod 3 in this embodiment is provided with the outward protruding portion 3a, which can first pass the end of the film through the outward protruding portion 3a, and then pull it toward the open end along the length direction of the winding rod 3, so that the end of the film is laid flat on the cylinder 1.

[0039] In yet another embodiment, a first through hole with a closed structure is provided to replace the notch.

[0040] In yet another embodiment, the number of the first notches 2a is set to three, four or other quantities, these first notches 2a are annularly distributed around the axis of the cylinder 1, and correspondingly, each first notch 2a is provided with a linear winding rod 3.

[0041] Preferably, this embodiment is further provided with a retaining ring 4, the retaining ring 4 is sleeved on the cylinder 1, the retaining ring 4 is attached to the side wall of the fixing member 2 and fixed to the fixing member 2, the retaining ring 4 is provided with a second notch 4a corresponding to the shape and position of the first notch 2a, the first notch 2a communicates with the second notch 4a, the end of the winding rod 3 sequentially passes through the second notch 4a and the first notch 2a, and the outer diameter of the retaining ring 4 is larger than the outer diameter of the fixing member 2. The retaining ring 4 can function to arrange and align the side edge of the wound film.

[0042] In this embodiment, the fixing member 2 and the retaining ring 3 are fixed by bolts, which facilitates the disassembly of the retaining ring 3. When the diameter of the film wound into a roll is large, the retaining ring 3 with a larger diameter can be replaced.
