Description

Technical Field

[0001] This utility model relates to the technical field of winding mechanism of blown film machine, specifically an automatic feeding mechanism for winding mechanism. Background Technology

[0002] In the blown film production process, the winding mechanism of the blown film machine plays a crucial role. Traditional blown film machine winding mechanisms, such as the common structure including a support, an active take-up roller, and a take-up roller, are responsible for winding and arranging the blown film in the film production process. The take-up support plate (take-up roller frame) is fixed on the support, providing the necessary support structure for the winding process. For a specific structure, please refer to the winding device for a blown film machine disclosed in application number CN2023116452525.

[0003] However, in traditional blown film machines, the film unwinding mechanism, once the take-up roller has finished winding the film, is currently mostly operated manually. Manually handling the wound take-up roller not only requires a significant amount of manpower, greatly increasing the labor intensity for workers, but also results in low efficiency, making it difficult to meet the demands of large-scale, high-efficiency production. This severely restricts the capacity expansion and economic benefits of blown film manufacturers. Therefore, developing an automatic unwinding mechanism has become a crucial issue that the blown film manufacturing industry urgently needs to address. Utility Model Content

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] This utility model provides an automatic unloading mechanism for a winding mechanism.

[0024] In this embodiment, refer to Figure 1-5 The automatic feeding mechanism of the winding mechanism includes a support 1, an active take-up roller 2, and a take-up roller 3. A take-up support plate 4 is fixed on the support 1. The feeding assembly also includes a feeding component. The feeding assembly includes a rotating shaft 5 rotatably connected to the support, a take-up arm 6 connected to the rotating shaft 5, a driving component 7 driving the take-up arm 6 to rotate around the axis of the rotating shaft 1, a rotating shaft 8 rotatably connected to the support, a feeding arm 9 connected to the rotating shaft 2, and a driving component 10 driving the feeding arm 9 to rotate around the axis of the rotating shaft 2. The upper end of the take-up arm is provided with a groove 11 for positioning the two ends of the take-up roller. The side wall of the groove 11 near the active take-up roller is higher than the other side wall and is provided as a limiting part 12. The upper end of the feeding arm is provided with an arc-shaped concave surface 14 for receiving the two ends of the take-up roller. The side of the arc-shaped concave surface 14 away from the active take-up roller has a receiving extension part 15.

[0025] The take-up support plates on both sides of the bracket are provided with support planes 18 that connect to the two ends of the take-up roller.

[0026] In the above technical solution, by adding a discharge assembly, this assembly includes a rotating shaft 1 rotatably connected to the support and a receiving arm connected thereto, a drive component 1 for driving the receiving arm to rotate, a rotating shaft 2 and a discharging arm connected thereto, and a drive component 2 for driving the discharging arm to rotate. The groove on the receiving arm, the arc-shaped concave surface on the discharging arm, and the receiving extension work together to realize the discharge operation of the winding roller. Power is provided by drive component 1 and drive component 2, causing the receiving arm and the discharging arm to rotate along a set axis, completing the transport of the winding roller, realizing automatic discharge of the winding roller, eliminating manual handling, and saving labor costs and labor intensity.

[0027] The specific principle is as follows: When the take-up roller completes take-up and needs to unload, the drive component drives the take-up arm to rotate towards the lower material arm until the take-up roller is pushed to the desired position. Figure 3 At the end of the supporting plane shown, synchronously, the second drive component drives the unloading arm to rotate towards the take-up roller. As the take-up roller continues to push forward, it loses the support of the supporting plane and falls onto the arc-shaped concave surface of the unloading arm. After receiving the material, the unloading arm is driven by the second drive component to rotate towards the ground until the unloading is completed. The unloaded take-up roller rolls out from the receiving extension onto the ground.

[0028] The receiving extension serves as a limit, preventing the received take-up roller from slipping out of the concave surface of the unloading arm. It also acts as a guide, helping the take-up roller roll out of the receiving extension onto the ground.

[0029] Among them, drive component one and drive component two can be cylinders commonly used in the field of automation.

[0030] Specifically, the two ends of the take-up roller are provided with bearings 16 that roll in cooperation with the take-up arm.

[0031] In this embodiment, bearings 16 are provided at both ends of the take-up roller to roll in conjunction with the take-up arm. When the take-up arm rotates under the action of the drive component, the bearings 16 contact and roll with the take-up arm, reducing the friction between the take-up roller and the take-up arm. This makes the movement of the take-up roller on the take-up arm smoother and reduces mechanical wear.

[0032] Specifically, the two ends of the take-up roller are provided with bearings 17 that roll in cooperation with the unloading arm.

[0033] In this embodiment, bearings 17 are provided at both ends of the take-up roller to roll in cooperation with the unloading arm. When the unloading arm rotates under the drive of the drive component 2 to receive the take-up roller, the bearings 17 contact and roll with the unloading arm, reducing the frictional resistance between them.

[0034] Specifically, the two ends of the take-up roller are provided with bearings 319 that roll in cooperation with the support plane.

[0035] In this embodiment, a support plane is provided on the bracket, and the bearings at both ends of the take-up roller roll roll with the support plane to reduce friction.

[0036] Specifically, the inner wall of the bracket is provided with a first limiting block 20 and a second limiting block 21.

[0037] In this embodiment, limit block one is used to limit the maximum stroke of the receiving arm rotating to the side of the lowering arm, and limit block two is used to limit the maximum stroke of the lowering arm rotating to the side of the receiving arm, so as to avoid overtravel operation.

[0038] Specifically, the receiving arm and the unloading arm are provided with weight reduction slots 22.

[0039] In this embodiment, weight-reducing slots are provided on the receiving arm and the unloading arm to reduce their weight by removing some material.

[0040] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
