Description

Technical Field

[0001] This utility model relates to the field of tension control technology, specifically to a tension control mechanism for a packaging pearl cotton winding device. Background Technology

[0002] Pearl cotton is a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles generated by the physical foaming of low-density polyethylene resin. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat insulation, good plasticity, strong toughness, recyclability, environmental protection, and strong impact resistance. It is widely used in various industrial and daily applications. In the production process of pearl cotton, winding is an important step.

[0003] In the initial stage of feeding, when the fabric passes through multiple guide rollers, it may be due to the fabric being wound too tightly during manual feeding, or the tension detected by the sensor being too low due to friction loss between the rollers. The system may mistakenly assume that the tension is insufficient and incorrectly increase or decrease the braking torque, resulting in excessive or too tight tension at the winding end, causing the fabric to be compressed thin. At this time, the operator can only stop the damage by cutting off the power in time and cannot control the fabric during the operation of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a tension control mechanism for a packaging pearl cotton winding device, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tension control mechanism for a packaging pearl cotton winding device, comprising a pearl cotton winding device body, and further comprising:

[0006] A tension adjustment structure is placed inside the body of the pearl cotton winding device. The tension adjustment structure includes a fixed frame connected to the body of the pearl cotton winding device, a tension roller connected to the fixed frame, a V-shaped lever connected to the tension roller, a sliding shaft connected to the side of the V-shaped lever away from the tension roller, a lifting rod connected to the sliding shaft, and a lever block connected to the bottom of the lifting rod through the sliding rod.

[0007] Furthermore, an electric telescopic rod is connected to the bottom of the lever, and the side of the electric telescopic rod away from the lever is connected to the body of the pearl cotton winding device. The V-shaped lever is connected to the body of the pearl cotton winding device via a rotating shaft.

[0008] The above technical solution is adopted: by setting a V-shaped lever, when the sliding shaft is moved to slide away from the body of the pearl cotton winding device, the tension roller fixed with the V-shaped lever can slide away from the body of the pearl cotton winding device.

[0009] Furthermore, a universal joint is connected to the V-shaped lever, and the side of the universal joint on the V-shaped lever away from the V-shaped lever is connected to the tension roller.

[0010] The above technical solution involves setting a universal joint on the V-shaped lever, which makes the connection between the tension roller and the V-shaped lever tighter during use.

[0011] Furthermore, a fixing block is connected to the main body of the pearl cotton winding device, and the sliding rod is connected to the fixing block.

[0012] The above technical solution is adopted: by setting a fixed block, it is convenient to use the fixed block to limit the sliding rod during use, and the sliding rod slides within the fixed block.

[0013] Furthermore, the main body of the pearl cotton winding device has an opening, and the sliding rod is connected to the opening on the main body of the pearl cotton winding device.

[0014] The above technical solution is adopted: by observing that there is an opening, the sliding rod is prevented from being blocked during use.

[0015] Furthermore, a lever is connected to the sliding rod, and a vertical hole is provided on the side of the pearl cotton winding device body near the sliding rod, with the lever connected to the vertical hole on the pearl cotton winding device body.

[0016] The above technical solution is adopted: by setting a lever, it is easy to connect the electric telescopic pole.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] In this invention, operators can directly observe the state of the pearl cotton during equipment operation. By controlling the electric telescopic rod, the tension roller can be driven to slide back and forth in real time. The tension increases when sliding upward and decreases when sliding downward, eliminating the need for sensor feedback delays or machine stop adjustments. This avoids misjudgments caused by signal delays or friction interference in traditional systems. At the same time, the universal joint ensures that the tension roller is perpendicular to the material, and the limiting design of the fixed block and the opening ensures adjustment stability. This enables dynamic real-time tension correction, improves winding quality and production continuity, reduces downtime, increases production efficiency, and avoids time-consuming operations such as material breakage and re-threading caused by tension loss of control in existing technologies.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] like Figures 1-5 As shown, this utility model provides a technical solution: a tension control mechanism for a packaging pearl cotton winding device, including a pearl cotton winding device body 1, and further comprising:

[0031] Tension adjustment structure 2 is placed inside the body 1 of the pearl cotton winding device. Tension adjustment structure 2 includes a fixed frame 21 fixedly connected to the body 1 of the pearl cotton winding device. A tension roller 22 is slidably connected to the fixed frame 21. A V-shaped lever 23 is connected to the tension roller 22. A sliding shaft 24 is fixedly connected to the side of the V-shaped lever 23 away from the tension roller 22. A lifting rod 28 is slidably connected to the sliding shaft 24. A lever block 27 is fixedly connected to the bottom of the lifting rod 28 through a sliding rod 26.

[0032] When using this invention, after fixing the material onto the main body 1 of the pearl cotton winding device, the main body 1 of the pearl cotton winding device is started, and the electric telescopic rod 32 is started simultaneously. This causes the electric telescopic rod 32 to drive the lever 27 to slide up and down, which in turn drives the sliding rod 26 to slide up and down. This causes the sliding rod 26 to drive the sliding shaft 24 to slide up and down, which in turn causes the lifting rod 28 to slide up and down. This causes the side of the V-shaped lever 23 closest to the sliding shaft 24 to slide up and down, which in turn drives the tension roller 22 to slide away from the main body 1 of the pearl cotton winding device. When the electric telescopic rod 32 drives the sliding rod 26 to slide down, the V-shaped lever 23 will drive the tension roller 22 to slide closer to the main body 1 of the pearl cotton winding device, thereby reducing the tension. The operator can adjust the up and down sliding of the electric telescopic rod 32 by observing the fabric.

[0033] like Figure 1 , Figure 2 , Figure 5 As shown, an electric telescopic rod 32 is fixedly connected to the bottom of the lever 27. The side of the electric telescopic rod 32 away from the lever 27 is fixedly connected to the body 1 of the pearl cotton winding device. The V-shaped lever 23 is rotatably connected to the body 1 of the pearl cotton winding device via the rotating shaft 3. By setting the V-shaped lever 23, when the sliding shaft 24 is moved to slide away from the body 1 of the pearl cotton winding device, the tension roller 22 fixed to the V-shaped lever 23 slides away from the body 1 of the pearl cotton winding device using the lever principle, thereby quickly adjusting the transmission tension of the pearl cotton.

[0034] A universal joint is fixedly connected to the V-shaped lever 23. The side of the universal joint on the V-shaped lever 23 away from the V-shaped lever 23 is fixedly connected to the tension roller 22. By fixing the universal joint to the V-shaped lever 23, the multi-angle adjustment requirements of the tension roller 22 can be adapted, ensuring that the connection between the tension roller 22 and the V-shaped lever 23 is tight and stable during use, and avoiding loosening or displacement during the adjustment process.

[0035] like Figures 2 to 5 As shown, a fixed block 25 is fixedly connected to the main body 1 of the pearl cotton winding device, and a sliding rod 26 is slidably connected to the fixed block 25. By setting the fixed block 25, the sliding rod 26 can be limited during use, so that it can slide smoothly within the fixed block 25, ensuring the stable operation of the tension adjustment structure 2 and preventing the sliding rod 26 from shifting and affecting the tension adjustment effect.

[0036] like Figures 1 to 3 as well as Figure 5 As shown, an opening is provided on the main body 1 of the pearl cotton winding device, and the sliding rod 26 is slidably connected in the opening on the main body 1 of the pearl cotton winding device. By opening the opening, sufficient space is provided for the sliding rod 26 to slide, effectively preventing the sliding rod 26 from being blocked during the movement, ensuring the smooth movement of the sliding rod 26, and ensuring the smooth operation of the tension adjustment.

[0037] A lever 27 is fixedly connected to the sliding rod 26. A vertical hole is provided on the side of the pearl cotton winding device body 1 near the sliding rod 26. The lever 27 is slidably connected in the vertical hole on the pearl cotton winding device body 1. By setting the lever 27, a convenient connection with the electric telescopic rod 32 can be achieved. At the same time, it is convenient to transmit the power of the electric telescopic rod 32, so that the sliding rod 26 can slide in a predetermined direction and stroke, thereby improving the ease of operation of tension control.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
