Description

Technical Field

[0001] This utility model relates to the field of high elastic cotton processing technology, specifically a wrinkle-resistant high elastic cotton hot pressing device. Background Technology

[0002] The high-elasticity cotton hot pressing device is a special equipment used to hot press high-elasticity cotton (also known as high-resilience cotton, elastic cotton, resilient sponge and similar materials) to form patterns on the high-elasticity cotton according to requirements.

[0003] For example, Chinese Patent CN219903338U discloses a hot-pressing device for elastic cotton surfaces, belonging to the field of elastic cotton surface hot-pressing technology. It includes a chassis, with a spreading assembly, an adhesive application assembly, and a film guiding assembly installed on the left end of the chassis; a transmission assembly installed at the bottom of the chassis; a hot-pressing assembly installed in the middle of the chassis; and a cooling assembly and a pushing assembly installed on the right end of the chassis. Through this method, the elastic cotton can be flattened and adsorbed onto a conveyor belt before hot pressing, ensuring that the elastic cotton will not wrinkle or shift due to its high elasticity during hot pressing, allowing it to remain flat and effectively bond with the film during hot pressing, thereby improving the quality of the elastic cotton hot-pressing film. Furthermore, by applying adhesive to the elastic cotton horizontally and pressing the film and elastic cotton together with a pressure roller, excess adhesive can be removed, making the adhesive more evenly distributed during hot pressing, improving the flatness of the elastic cotton film, and further enhancing the film quality.

[0004] Traditional hot pressing devices have uneven temperature distribution in the heating area, which can easily affect the processing quality of high-elasticity cotton due to local overheating or insufficient heating. The asynchronous movement of the upper and lower heating components leads to inconsistent heating gaps, which in turn affects the heating effect. Utility Model Content

[0017] 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.

[0018] Example 1: Please refer to Figures 1 to 4 The present invention provides the following technical solution: A wrinkle-resistant, high-elasticity cotton hot-pressing device includes an insulating shell 1, a top plate 2 fixedly connected to the top of the insulating shell 1, and two open structures on both sides of the insulating shell 1. Three equidistant telescopic rods 3 are fixedly connected to the top of the top plate 2. A heating component is installed in the middle of the interior of the insulating shell 1. The heating component includes fixed frames 4 fixedly connected to the interior of the insulating shell 1 and symmetrically distributed. Each fixed frame 4 has a sliding rod 5 at both ends. A hollow-structured carrier plate 6 is fixedly connected to the middle position inside the two fixed frames 4. Each carrier plate 6 has a sliding groove on both sides. Two symmetrically distributed synchronous sliders 8 are slidably connected inside each sliding groove. Two synchronous connecting rods 9 are rotatably connected to the outside of each synchronous slider 8. Adjustment components are provided at both ends of the insulating shell 1. A wrinkle-removing component and a hot-pressing component are respectively installed inside the two adjustment components.

[0019] Two synchronous connecting rods 9 rotating on the outer side of the synchronous slider 8 are spliced ​​together to form a rhomboid connecting rod assembly. The four sliding rods 5 are all slidably connected to mounting plates 10. The mounting plates 10 are symmetrically distributed on the upper and lower sides of the carrying plate 6. The top of the two fixed frames 4 are fixedly connected to connecting plates 7. The telescopic rod 3 located in the middle of the top of the top plate 2 passes through the connecting plate 7 and is connected to the mounting plate 10 on the top of the carrying plate 6. The mounting plates 10 are fixedly connected to fixed shafts 11 on both sides. The end of the synchronous connecting rod 9 away from the synchronous slider 8 is rotatably connected to the outside of the fixed shaft 11, and the four rotation points of the rhomboid structure rotate around the two synchronous connecting rods 9 and the two synchronous sliders 8.

[0020] A heat spreader plate 12 with equal spacing is fixedly connected to the side of the mounting plate 10 near the load plate 6. A heating wire 13 is fixedly connected between the mounting plate 10 and the heat spreader plate 12. The density of the heating wire 13 between the mounting plate 10 and the heat spreader plate 12 is higher as it is closer to the hot pressing assembly. A flexible cable 14 is fixedly connected to the power supply end of the heating wire 13. The flexible cable 14 is connected to the power supply module.

[0021] The power supply module supplies power to the heating wire 13 through the flexible cable 14. After the heating wire 13 is powered on, it generates heat. The heat is conducted and diffused through the heat spreader 12. Since the density of the heating wire 13 is higher closer to the hot pressing component between the mounting plate 10 and the heat spreader 12, the heat spreader 12 will form a gradient heating effect that gradually increases from far to near.

[0022] When the telescopic rod 3 located in the middle of the top of the top plate 2 is activated, its output end pushes or pulls the mounting plate 10 on the top of the load plate 6 in the vertical direction. Under the limiting action of the four sliding rods 5, the mounting plate 10 moves smoothly along the length of the sliding rods 5. At the same time, the fixed shafts 11 on both sides of the mounting plate 10 move synchronously with the mounting plate 10.

[0023] The movement of the fixed shaft 11 causes the synchronous connecting rod 9, which is rotatably connected to it, to deflect. Since the synchronous slider 8 is slidably connected in the grooves on both sides of the carrying plate 6, and the two synchronous connecting rods 9 on the outer side of each synchronous slider 8 are spliced ​​together to form a rhomboid connecting rod assembly, the deflection of the synchronous connecting rod 9 pushes the synchronous slider 8 to slide symmetrically in the horizontal direction in the groove. The rhomboid connecting rod assembly undergoes adaptive deformation, thereby causing the mounting plate 10 below the carrying plate 6 to move synchronously closer to or away from the top mounting plate 10 along the sliding rod 5 symmetrically.

[0024] When the symmetrical mounting plate 10 moves the heat spreader 12 toward the carrier plate 6, it can perform gradient heating on the high-elasticity cotton passing through the hollowed-out carrier plate 6. The heat insulation shell 1 can reduce the loss of internal heat to the outside and maintain the temperature stability of the heating area. The fixing frame 4 and the connecting plate 7 provide structural support for the entire heating assembly and ensure the structural stability during the movement.

[0025] Example 2: Based on Example 1, please refer to... Figure 5 and Figure 6 The following structure was also disclosed: The adjustment assembly includes fixed rods 15 fixedly connected to both ends of the top plate 2. Four fixed rods 15 are provided at each end of the heat spreader 12 and are arranged in a rectangular shape. Fixed plates 16 are fixedly connected to the inner side of the lower end of the four fixed rods 15. An adjustment plate 17 is slidably connected between the top plate 2 and the fixed plate 16 through the four fixed rods 15. Telescopic rods 3 located at both ends of the top of the heat insulation shell 1 pass through the top plate 2 and are fixedly connected to the top of the adjustment plate 17. Bearing seats are fixedly connected to the sides of the fixed plate 16 and the adjustment plate 17 that are close to each other.

[0026] The wrinkle removal assembly includes a transport roller 18 mounted on a fixed plate 16 and an adjusting plate 17 via a bearing seat. A pad 19 is fixedly connected between two transport rollers 18 on the top of the fixed plate 16. The transport rollers 18 are driven by a motor and rotate synchronously in opposite directions on the fixed plate 16 and the adjusting plate 17.

[0027] The hot pressing assembly includes a support roller 20 mounted on an adjusting plate 17 via a bearing seat, and a pressure roller 21 rotatably connected to a fixed plate 16 via a bearing seat. The support rollers 20 and pressure rollers 21 correspond one-to-one and are equidistantly distributed. There are at least three sets of support rollers 20 and pressure rollers 21. The texture on the outer side of each support roller 20 is distributed from light to dark. The support rollers 20 and pressure rollers 21 are driven by a motor and rotate synchronously in opposite directions.

[0028] The position of the adjusting plate 17 is adjusted by the telescopic rods 3 at both ends of the top of the heat insulation shell 1. The output end of the telescopic rod 3 pushes or pulls the adjusting plate 17, so that the adjusting plate 17 slides between the top plate 2 and the fixed plate 16 along the fixed rod 15 until the transport roller 18 of the wrinkle removal component and the support roller 20 of the hot pressing component are adapted to the thickness of the high elastic cotton to be treated.

[0029] After startup, the motor drives the transport roller 18 of the wrinkle removal component to operate. The transport roller 18, which is installed on the fixed plate 16 and the adjusting plate 17, rotates synchronously in opposite directions, conveying the high elastic cotton from the open side of the heat insulation shell 1 to the inside of the device. The pad 19 between the two transport rollers 18 at the top of the fixed plate 16 can support the lower transport roller 18, enhance the compression stability of the high elastic cotton by the transport roller 18 during the conveying process, and reduce the wrinkles generated by the high elastic cotton in the early stage of conveying.

[0030] After the high-elastic cotton is conveyed to the heating component area by the wrinkle removal component, the mounting plates 10 on the upper and lower sides of the carrier plate 6, under the linkage of the middle telescopic rod 3, the synchronous connecting rod 9 and the synchronous slider 8, use the heat spreader 12 to gradient heat and soften the high-elastic cotton, in preparation for subsequent hot pressing and wrinkle prevention.

[0031] The heated high-elasticity cotton continues to be conveyed to the hot-pressing assembly. Support rollers 20 and pressure rollers 21 work in a one-to-one correspondence to compress and heat-press the cotton. The textured surface of the support rollers 20, ranging from light to dark, gradually increases the heat pressure. At least three sets of support rollers 20 and pressure rollers 21 enable multiple continuous hot-pressing processes, further improving the smoothness and wrinkle resistance of the high-elasticity cotton. Throughout the operation, the bearing seats on the fixed plate 16 and adjusting plate 17 provide rotational support for the transport rollers 18, support rollers 20, and pressure rollers 21. The adjusting assembly can adjust the height of the relevant rollers in real time via the telescopic rods 3 at both ends to adapt to the processing requirements of high-elasticity cotton of different thicknesses.
