Description

Technical Field

[0001] This utility model belongs to the technical field of winding devices, specifically relating to a winding device for processing EPE pearl cotton. Background Technology

[0002] Polyethylene foam, also known as EPE pearl cotton, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles created through the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also has good chemical resistance. However, due to its strong resilience and toughness, EPE foam tends to expand outwards during the winding process, making it difficult to tighten and resulting in a loose feel. Currently, loosely rolled EPE foam still requires manual tightening, which is time-consuming and labor-intensive.

[0003] Chinese patent No. 2020216217334 discloses a winding machine for pearl cotton production and processing, including a base plate, with symmetrical first vertical rods fixed on one side of the top surface of the base plate, a base between the two first vertical rods, a motor embedded in the top of the base, a winding roller rotatably mounted between the upper adjacent surfaces of the two first vertical rods via a rotating shaft, a transmission belt between the rotating shaft of the motor and the rotating shaft of the winding roller, a central shaft protruding from the top center of the first vertical rod, a pressing assembly slidably mounted between the two central shafts, the pressing assembly including a slider slidably sleeved on the outside of the central shaft, and a spring sleeved on the outside of one end of the central shaft passing through the slider.

[0004] The above solution uses a spring sleeved on the outside of one end of the slider through the central shaft. A top cover is fixedly connected to the top of the central shaft, passing through the slider and spring. The top and bottom ends of the spring are fixedly connected to the bottom surface of the top cover and the top surface of the slider, respectively. This makes the wound pearl cotton roll more compact and prevents it from collapsing. However, the pearl cotton winding machine lacks a tensioning mechanism to tighten the pearl cotton. The pearl cotton remains relatively loose when wound on the winding roller, which is the main reason for the large volume of the wound pearl cotton and its inconvenience for storage. Utility Model Content

[0005] To solve the above problems, this utility model provides a winding device for processing EPE pearl cotton, including a tensioning mechanism and a winding mechanism. The tensioning mechanism and the winding mechanism are arranged sequentially along the winding direction. The tensioning mechanism includes a tensioning frame and a tensioning roller. First vertical plates are provided on both sides above the tensioning frame. Guide rods are provided on opposite sides of the two first vertical plates. Sliding blocks are provided on the two guide rods. A tensioning roller is rotatably arranged between the two sliding blocks. A crossbeam is provided above the two first vertical plates. A first guide roller is rotatably arranged between one end of the two crossbeams. A second guide roller is rotatably arranged between the other ends of the two crossbeams. The first guide roller, the tensioning roller and the second guide roller form a V-shaped structure. The winding mechanism includes a winding frame and a winding roller. Second vertical plates are provided on both sides above the winding frame. A winding roller is rotatably arranged above the two second vertical plates.

[0006] Preferably, the first upright plate has an upper support plate and a lower support plate on the side near the guide rod, the guide rod is located between the upper support plate and the lower support plate, the upper support plate is provided with a telescopic motor, and the output end of the telescopic motor passes downward through the upper support plate and is connected to the sliding block.

[0007] Preferably, a pressure sensor is provided between the output end of the telescopic motor and the sliding block.

[0008] Preferably, the bottom of the winding frame is provided with support blocks and support feet, and a weight sensor is provided between the support blocks and support feet. The side of the second upright plate is provided with a motor base, and a drive motor is provided on the motor base. The output end of the drive motor is connected to the winding roller.

[0009] Preferably, the surface of the tensioning roller is provided with a chrome-plated coating.

[0010] The advantages of this utility model are:

[0011] 1. In this design, the tension roller is mounted on the guide rod via a sliding block. This design allows the position of the tension roller to be flexibly adjusted according to the tension requirements of the EPE foam. When the EPE foam becomes loose or too tight during winding, the tension can be adjusted by changing the position of the tension roller, ensuring that the EPE foam is always under appropriate tension, thereby improving the winding quality.

[0012] 2. In this design, the first guide roller, the tension roller, and the second guide roller are arranged in a V-shape. This layout can better guide the conveying direction of the pearl cotton, reduce the friction and resistance of the pearl cotton during the conveying process, and also help the pearl cotton to be evenly stressed during the tensioning process, thereby further improving the tensioning effect.

[0013] 3. The tension roller described in this solution has a chrome-plated coating on its surface, which extends the service life of the tension roller, reduces the frequency of replacement due to wear of the tension roller, thereby reducing equipment maintenance costs and downtime, and improving production efficiency.

In short, those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1, such as Figure 1-2 As shown, a winding device for processing EPE (Expanded Polyethylene) foam includes a tensioning mechanism and a winding mechanism, which are arranged sequentially along the winding direction. The tensioning mechanism includes a tensioning frame 1 and a tensioning roller 2. First vertical plates 3 are provided on both sides above the tensioning frame 1. Guide rods 4 are provided on opposite sides of the two first vertical plates 3, and sliding blocks are provided on both guide rods 4. A tensioning roller 2 is rotatably mounted between the two sliding blocks. A crossbeam 5 is provided above the two first vertical plates 3. A first guide roller 6 is rotatably mounted between one end of the two crossbeams 5, and a second guide roller 7 is rotatably mounted between the other ends of the two crossbeams 5. The tensioning roller 2 is mounted on the guide rods 4 via sliding blocks. This design allows the position of the tensioning roller 2 to be flexibly adjusted according to the tension requirements of the EPE foam. When the EPE foam becomes loose or too tight during winding, the tension can be adjusted by changing the position of the tensioning roller 2, ensuring that the EPE foam is always in a suitable tension state, thereby improving the winding quality. The guide rods 4 set on the two first upright plates 3 provide stable guidance for the sliding block, ensuring that the tensioning roller 2 remains stable during movement and avoiding uneven tension or damage to the pearl cotton due to shaking.

[0023] The first guide roller 6, tension roller 2, and second guide roller 7 form a V-shaped structure. The winding mechanism includes a winding frame 8 and a winding roller 9. Second vertical plates 10 are located on both sides above the winding frame 8, and the winding roller 9 is rotatably mounted above the two second vertical plates 10. This V-shaped structure between the first guide roller 6, tension roller 2, and second guide roller 7 better guides the conveying direction of the pearl cotton, reducing friction and resistance during conveying. It also helps the pearl cotton to be evenly stressed during tensioning, further improving the tensioning effect. The winding mechanism consists only of the winding frame 8, the second vertical plates 10, and the winding roller 9, making it simple in structure and easy to operate. By rotatably mounting the winding roller 9 above the two second vertical plates 10, the tensioned pearl cotton can be directly and efficiently wound up, reducing unnecessary transmission parts, lowering equipment costs, and reducing failure rates. The surface of the tension roller 2 is coated with a chrome plating 20, extending its service life and reducing the frequency of replacement due to wear, thereby reducing equipment maintenance costs and downtime, and improving production efficiency. For example, without the chrome plating 20, the tension roller 2 might need to be replaced every few months, while with the chrome plating 20, its service life could be extended to a year or even longer. Figure 3 The tensioning roller 2 can directly use its own gravity to apply tension to the pearl cotton, ensuring that the pearl cotton is always in a suitable tension state.

[0024] Combination Figure 4 The first upright plate 3 has an upper support plate 11 and a lower support plate 12 on the side near the guide rod 4. The guide rod 4 is located between the upper support plate 11 and the lower support plate 12. A telescopic motor 13 is mounted on the upper support plate 11, and the output end of the telescopic motor 13 passes downward through the upper support plate 11 and connects to the sliding block. The telescopic motor, as a power source, can precisely control the telescopic displacement of the output end. By programming or preset parameters, the sliding block can be moved along the guide rod 4 to a designated position, so that the tensioning roller 2 can achieve a precise tension adjustment effect. The pressure sensor 14 can sense the pressure applied to the sliding block by the output end of the telescopic motor 13 in real time and transmit this data to the control system. This allows the control system to precisely adjust the output force of the telescopic motor 13 according to the actual tension requirements of the pearl cotton, ensuring that the tension applied to the pearl cotton by the tensioning roller 2 is always within a suitable range.

[0025] The bottom of the winding frame 8 is equipped with support blocks 15 and support feet 16. A weight sensor 17 is installed between the support blocks 15 and support feet 16. A motor base 18 is installed on the side of the second upright plate 10, and a drive motor 19 is installed on the motor base 18. The output end of the drive motor 19 is connected to the winding roller 9. The support blocks 15 and support feet 16 at the bottom of the winding frame 8 provide a stable and reliable support foundation for the entire winding device. During the winding process, the winding roller 9 continuously winds the pearl cotton, and the overall weight of the equipment gradually increases. The stable support structure can effectively prevent the equipment from shaking or tilting, ensuring smooth winding operations. The weight sensor 17 installed between the support blocks 15 and support feet 16 can measure the weight of the pearl cotton in real time and accurately. The data fed back by the weight sensor 17 can promptly detect any abnormalities that may occur during the winding process. For example, if the rate of weight increase is abnormal, it may mean that the pearl cotton conveying speed is unstable or there are problems such as leakage. Operators can check and solve these problems in time to ensure product quality.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
