DETAILED DESCRIPTION

[0032] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0033] Referring to Figures 1-3 The utility model provides a kind of embodiment provided by the utility model: a kind of phenolic cotton cloth laminated board preparation is used laminating machine, including base 1, base 1 top is fixedly connected with shell 2, shell 2 inside rotationally connected with conveying roller 15, for conveying phenolic cotton cloth, phenolic cotton cloth is transported to heating area by the rotation of conveying roller 15, to carry out subsequent pressing treatment. Base 1 top is fixedly connected with bottom plate 3, and bottom plate 3 is the basic component of supporting entire equipment, and provide stable platform support, ensure the stability of accurate operation and long time operation of equipment.

[0034] The adjusting assembly comprises a fixed plate 4, inside which a tooth column 10 is slidably connected, which is used to realize the adjustment of pressure, and the position thereof is controlled by sliding to adjust the force of pressing. One side of the fixed plate 4 is rotatably connected with a rotating shaft 7, which is used to transmit the rotary power, so that the whole adjusting structure can stably operate. The outer wall of the rotating shaft 7 is fixedly connected with a worm wheel 9, which is driven by the meshing with a worm 6, and in turn drives the rotation of a gear 8. The outer wall of the rotating shaft 7 is fixedly connected with the gear 8, which is meshed with the teeth of the tooth column 10, so that the tooth column 10 can accurately adjust the position through the cooperative action of the gear 8 and the tooth column 10. One side of the fixed plate 4 is provided with a driving assembly, which drives the worm 6 of the output end of a motor 5 to rotate the worm wheel 9, and provides power support. The bottom of the tooth column 10 is fixedly connected with an extension rod 11, which adjusts the pressure through the extension and retraction movement, ensures the accurate controllability of the pressure between the heating plate 14 and the top plate 13, and further enhances the adaptability of the equipment to different sizes of phenolic cotton cloth. The bottom of the extension rod 11 is fixedly connected with the top plate 13, which is used to apply pressure to press the phenolic cotton cloth. The bottom of the top plate 13 is fixedly connected with the heating plate 14, which provides heating function, and ensures that the phenolic cotton cloth can be fully pressed and solidified under the action of pressure. The outer wall of the extension rod 11 is sleeved with a first spring 12, which is used to provide a reverse force when the pressure is released, so as to ensure the stable operation of the structure. One end of the first spring 12 is fixedly connected at the bottom of the tooth column 10, and the other end is fixedly connected at the top of the top plate 13, which can effectively control the adjustment range of the pressure through the elastic action of the spring, and avoid the influence of excessive pressure on the laminating process. The driving assembly comprises a motor 5, the output end of which is fixedly connected with a worm 6, which is meshed with a worm wheel 9 to drive the rotation of a rotating shaft 7, so as to control the action of the whole adjusting structure;

[0035] Specifically, the phenolic cotton cloth enters between the conveying rollers 15 stably and smoothly under the guidance of the guide plate 19, and the conveying rollers 15 convey the phenolic cotton cloth precisely to the space between the heating plate 14 and the bottom plate 3 through uniform and reliable transmission, laying a foundation for the subsequent pressing operation. After the phenolic cotton cloth enters, the heating plate 14 starts to heat uniformly to provide the necessary temperature conditions, thereby ensuring that the physical properties of the phenolic cotton cloth are activated and optimized. At the same time, the output end of the motor 5 drives the worm 6 to rotate at high speed, and the worm 6 drives the rotating shaft 7 to rotate at a stable speed through high-efficiency meshing transmission with the worm wheel 9. The rotating shaft 7 further drives the tooth column 10 to move downward through the power transmission of the gear 8. During the downward movement of the tooth column 10, the bottom end of the tooth column 10 exerts pressure on the first spring 12, compresses the first spring 12 and accumulates elastic potential energy. At the same time, the first spring 12 applies its compression force to the top plate 13, and further transmits the pressure to the heating plate 14 through the top plate 13, thereby exerting the required pressing force between the heating plate 14 and the bottom plate 3. By adjusting the deformation degree of the first spring 12, the pressure exerted by the heating plate 14 on the bottom plate 3 can be accurately adjusted, ensuring the uniformity and controllability of the pressing tension, and finally realizing high-quality laminating processing of the phenolic cotton cloth, effectively improving the strength and uniformity of the laminated board.

[0036] Reference Figure 4 and Figure 5The base 1 is internally provided with an adjusting groove 16, which provides a sliding path for the sliding block 18, so that the sliding block 18 can be adjusted in position as needed inside the base 1. The base 1 is also internally provided with a positioning groove 17, which is used to engage with the clamping block 21 to ensure the accurate fixing of the position of the sliding block 18 during adjustment, avoiding unnecessary displacement. The base 1 is internally provided with a sliding block 18, which is part of the adjusting assembly, and its function is to provide an adjustable support platform, which can realize accurate positioning of other components through sliding adjustment. The sliding block 18 is slidingly connected inside the adjusting groove 16, so that the sliding block 18 can smoothly slide in the groove and flexibly adjust the position to adapt to different sizes or needs of the operation. The top of the sliding block 18 is fixedly connected with a guide plate 19, which functions to guide the phenolic cotton cloth to the appropriate position, ensuring that the phenolic cotton cloth will not deviate or be unstable during subsequent processing. The sliding block 18 is internally slidingly connected with symmetrically arranged limiting plates 20, which mainly function to provide limiting for the sliding block 18 to prevent it from exceeding the predetermined working range during adjustment. The limiting plate 20 is fixedly connected with a clamping block 21 on one side, which functions to slidingly connect inside the sliding block 18 and engage with the positioning groove 17 to accurately lock the position of the sliding block 18, ensuring the stability and accuracy of the equipment during operation. The sliding block 18 is internally provided with a second telescopic rod 22, which can be telescoped as needed to adjust the height or pressure of the corresponding components. The second telescopic rod 22 is externally sleeved with a second spring 23, which functions to provide elastic support for the second telescopic rod 22 to ensure that the telescopic rod can return to the initial position after being stressed, avoiding deformation or damage after long-term use. The second telescopic rod 22 and the second spring 23 are fixedly connected between the limiting plates 20, and the presence of the limiting plates 20 ensures that the second telescopic rod 22 will not deviate during telescoping, while maintaining the stability and reliability of the structure;

[0037] Specifically, when adjusting the spacing between the guide plates 19, the guide plates 19 are smoothly slid in the adjusting grooves 16 by the sliding blocks 18 and accurately adjusted under the guidance of the adjusting grooves 16. The design of the sliding blocks 18 enables the guide plates 19 to be flexibly adjusted according to actual needs, thereby adapting to the processing requirements of phenolic cotton cloth of different sizes. In order to ensure the accurate positioning of the guide plates 19, the sliding blocks 18 are firmly embedded with the positioning grooves 17 through the internally arranged clamping blocks 21, thereby ensuring that the guide plates 19 do not deviate during the adjustment process. At the same time, the clamping blocks 21 are effectively limited by the limiting plates 20, thereby avoiding errors caused by excessive movement during the adjustment process. The second springs 23 play a crucial supporting role in this process, and the elastic tension thereof ensures that the clamping blocks 21 are not easily misaligned when embedded with the positioning grooves 17, and are always maintained at the accurate positioning position. This precise adjustment mechanism not only ensures the stability and adaptability of the guide plates 19 during the processing of phenolic cotton cloth of different sizes, but also improves the overall efficiency of the equipment, ensures the stable and accurate conveying of the phenolic cotton cloth during the processing, and greatly improves the processing quality and precision of the laminated board.

[0038] Working principle: when the phenolic cotton cloth laminated board is used in a laminating machine, first, adjust the spacing between the guide plates 19, the guide plates 19 are limited in the adjusting grooves 16 by the sliding blocks 18, the guide plates 19 are adjusted by the sliding blocks 18 in the adjusting grooves 16, then the sliding blocks 18 are embedded with the positioning grooves 17 through the internally arranged clamping blocks 21, the clamping blocks 21 are limited by the limiting plates 20, and the clamping blocks 21 are not easily misaligned when embedded in the positioning grooves 17 through the tension support of the second springs 23, thereby achieving the effect of adapting to phenolic cotton cloth of different sizes;

[0039] Then the phenolic cotton cloth enters between the guide plates 19 and the conveying rollers 15, and is conveyed to between the heating plate 14 and the bottom plate 3 by the conveying rollers 15. Then the heating plate 14 is heated, the motor 5 outputs end drives the worm 6 to rotate, the worm 6 drives the rotating shaft 7 to rotate through the worm gear 9, the rotating shaft 7 drives the tooth column 10 to descend through the gear 8, the tooth column 10 descends to extrude the first spring 12, and then the first spring 12 presses the top plate 13, and then the pressure of the heating plate 14 on the bottom plate 3 is adjusted through the deformation degree of the first spring 12, thereby achieving the effect of adjusting the pressing force.
