Description

Technical Field

[0001] This utility model relates to the field of impregnated paper production, and more specifically, to a rewinding machine for impregnated paper production. Background Technology

[0002] The production of impregnated paper begins with carefully selected base paper. After pretreatment to remove impurities, it is impregnated with modified resin solution at a uniform speed. Precise control of parameters such as temperature and speed ensures uniform penetration of the resin layer. Subsequently, it undergoes processes such as drying, curing, and cooling to set the shape, resulting in decorative materials with wear-resistant and moisture-proof properties. A rewinding machine is required in the production process of impregnated paper.

[0003] When using existing rewinding machines for coated paper production, the tension on the coated paper is difficult to maintain as the winding operation continues. When the tension is too low, the paper is prone to loosening during the transport and winding process, which leads to wrinkles, seriously affecting the surface smoothness and quality of the coated paper, resulting in an increased product defect rate and a waste of raw materials and production costs.

[0004] Furthermore, in the traditional application scenarios of rewinding machines used in the production of coated paper, the winding rolls are generally assembled with the equipment in a fixed connection manner. When it is necessary to replace the winding roll that has been fully loaded with coated paper, tools are required to complete the replacement operation, which is relatively troublesome and affects work efficiency.

[0005] Therefore, we have made improvements to this and proposed a rewinding machine for the production of coated paper. Utility Model Content

[0034] To address the technical problems in the background section, the following rewinding machine for producing coated paper is provided:

[0035] Combination Figure 1 - Figure 6 As shown, the present invention provides a rewinding machine for producing coated paper, comprising a housing 1, inside which a first rotating roller 2 and a second rotating roller 3 are rotatably connected, and a tension adjustment mechanism 4 is provided between the first rotating roller 2 and the second rotating roller 3. Fixing plates 5 are fixedly installed on both sides of the housing 1, and rotating blocks 6 are rotatably connected to one side of each fixing plate 5. A take-up roller 7 is provided between two rotating blocks 6, and a connecting mechanism 8 is provided between the take-up roller 7 and the rotating blocks 6. A motor 9 is fixedly installed on the surface of one fixing plate 5. The output end of 9 is fixedly connected to the rotating block 6 on one side; the tension adjustment mechanism 4 includes a mounting frame 401, and an adjusting roller 402 is rotatably connected inside the mounting frame 401. A mounting plate 403 is fixedly installed on the lower surface of the mounting frame 401, and a lifting plate 404 is connected to the lower side of the mounting plate 403. Two hydraulic rods 405 are fixedly installed at the bottom of the housing 1, and the top of the hydraulic rods 405 is fixedly connected to the bottom of the lifting plate 404. A fixed frame 406 is fixedly installed at the bottom of the housing 1, and the lifting plate 404 is slidably connected to the fixed frame 406.

[0036] In this embodiment: the housing 1 is an integral support frame, with a first rotating roller 2 and a second rotating roller 3 rotating inside, and a tension adjustment mechanism 4 is provided between them. When the tension needs to be adjusted, the hydraulic rod 405 extends and retracts, causing the lifting plate 404 to slide stably within the fixed frame 406, thereby moving the mounting frame 401 and the adjusting roller 402 to achieve a wide range of initial tension adjustment, ensuring proper tension when the impregnated paper is wound. At the same time, the rotating blocks 6 on the fixed plates 5 on both sides of the housing 1 are connected to the winding roller 7 through the connecting mechanism 8, and are driven by the motor 9 to facilitate the winding of the impregnated paper.

[0037] In a preferred embodiment, the top of the lifting plate 404 is provided with a mounting groove 407, and the mounting plate 403 is slidably connected to the mounting groove 407. A plurality of first springs 408 are fixedly installed between the bottom of the mounting plate 403 and the mounting groove 407.

[0038] In this embodiment, the first spring 408 can continuously apply force to the upper adjusting roller 402 through its own elasticity, thereby providing effective support for the passing dipped paper, preventing the paper from loosening during the winding process, thus avoiding wrinkles and affecting the flatness and quality of the dipped paper.

[0039] In a preferred embodiment, a limiting rod 409 is provided inside the first spring 408, and the limiting rod 409 is fixedly installed at the bottom of the mounting groove 407. A limiting groove 410 is provided on the lower surface of the mounting plate 403, and the limiting rod 409 is slidably connected to the limiting groove 410.

[0040] In this embodiment: the limiting rod 409 is slidably connected to the limiting groove 410, which can limit the deformation direction of the first spring 408, avoid the situation of tilting and jamming when the mounting plate 403 slides, make the tension adjustment more stable, and ensure the winding quality of the impregnated paper.

[0041] In a preferred embodiment, the connecting mechanism 8 includes a slide groove 801, which is formed inside the rotating blocks 6 on both sides. A stop block 802 is slidably connected inside the slide groove 801, and a locking block 803 is fixedly installed on the surface of the stop block 802. The locking block 803 is a rectangular block. Both ends of the winding roller 7 are provided with slots 804, and the slots 804 are engaged with the locking blocks 803. A second spring 805 is fixedly installed between the stop block 802 and the inner wall of the slide groove 801.

[0042] In this embodiment: Slide grooves 801 are formed inside the rotating blocks 6 on both sides. A stop block 802 is slidably connected within the slide groove 801. A rectangular locking block 803 is fixed to the surface of the stop block 802. Corresponding locking slots 804 are formed at both ends of the take-up roller 7, which can engage with the locking blocks 803. Through the rectangular locking blocks 803, when the rotating blocks 6 rotate, the take-up roller 7 can be driven to rotate. The second spring 805 inside the slide groove 801 can use its own elasticity to press against the stop block 802 and the locking block 803, ensuring that the locking block 803 is always locked within the locking slot 804.

[0043] In a preferred embodiment, the upper and lower surfaces of the slide groove 801 are provided with connecting grooves 806, and connecting blocks 807 are slidably connected inside the connecting grooves 806. The two connecting blocks 807 are respectively fixedly installed on the upper and lower surfaces of the stop block 802. The rotating block 6 is slidably connected to the outside of the sliding ring 808, and the other ends of the two connecting blocks 807 are fixedly connected to the sliding ring 808.

[0044] In this embodiment: the moving sliding ring 808 can drive the connecting block 807 to move within the connecting groove 806, thereby controlling the position of the stop block 802 within the sliding groove 801, and driving the locking block 803 to move, which facilitates the installation and removal of the take-up roller 7.

[0045] In a preferred embodiment, a flattening roller 10 is rotatably connected inside the housing 1, and the flattening roller 10 is disposed between the second rotating roller 3 and the winding roller 7.

[0046] In this embodiment: when the sizing paper passes over the flattening roller 10, it will drive the flattening roller 10 to rotate. Through the rotation of the flattening roller 10, a uniform and appropriate tension can be applied to the sizing paper, gradually smoothing out the wrinkles and bends on the surface of the sizing paper, so that the sizing paper is transported to the winding roller 7 in a flat state for winding, thereby effectively improving the winding quality of the sizing paper and avoiding problems such as uneven winding and inconvenience in subsequent use caused by wrinkles.

[0047] Specifically, the working principle of this solution is as follows:

[0048] During use, the first rotating roller 2 and the second rotating roller 3 inside the housing 1 are used to guide the transfer of the coated paper. The tension adjustment mechanism 4 is used to adjust the tension. The hydraulic rod 405 extends and retracts, causing the lifting plate 404 to slide within the fixed frame 406, which in turn moves the mounting frame 401 and the adjusting roller 402, achieving a wide range of initial tension adjustment. At the same time, the first spring 408 continuously applies force to the adjusting roller 402 to prevent the paper from loosening. The limiting rod 409 cooperates with the limiting groove 410 to ensure smooth tension adjustment.

[0049] Motor 9 drives the rotating block 6 on one side to rotate, and the connecting mechanism 8 causes the take-up roller 7 to rotate and rewind. The rectangular locking block 803 engages with the locking slot 804, and the rotating block 6 can drive the take-up roller 7 to rotate. The second spring 805 ensures that the locking block 803 is firmly locked in the locking slot 804. The movable sliding ring 808 can drive the connecting block 807 and the stop block 802 to move, which facilitates the installation and removal of the take-up roller 7. The flattening roller 10 is located between the second rotating roller 3 and the take-up roller 7. When the coated paper passes around, it drives the roller to rotate. The flattening roller 10 applies uniform tension to the coated paper, smooths out wrinkles, and allows the coated paper to be rolled flat onto the take-up roller 7, improving the winding quality.

[0050] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0051] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
