[0029] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] See also Figures 1 to 6 A pressure-adjustable calender comprises a frame 1, an upper roller 2 and a lower roller 3 pivotally mounted on the frame 1, a cloth guide roller group 4 for guiding and tensioning the cloth to move in a predetermined direction, a cylinder 5 mounted on the frame 1, and a lever arm 6 connecting the end of the upper roller 2 and the output end of the cylinder 5.

[0031] The present invention discloses a pressure-adjustable calender, which realizes precise control of the calendering pressure by arranging an upper roller and a lower roller on a frame and adjusting the pressure of the upper roller using a combined structure of a cylinder and a lever arm. Compared with the traditional solid roller extrusion method, this scheme has a wider pressure adjustment range and can meet the requirements of different fabrics and coating processes.

[0032] Furthermore, as a preferred embodiment of the present invention but not limiting, it includes two cylinders 5 respectively located on both sides of the frame 1, and two lever arms 6 respectively pivotally connected to the two ends of the upper roller 2 and correspondingly connected to the cylinders 5 on the left and right sides.

[0033] In this embodiment, two cylinders are arranged on both sides of the frame and are respectively connected to the lever arms at both ends of the upper roller, so that the pressure of the upper roller can be accurately adjusted. When the pressure between the upper roller and the lower roller needs to be increased, the cylinder contracts and squeezes the upper roller downward through the lever arm, thereby increasing the pressure; when the pressure needs to be reduced, the cylinder extends and pushes the lever arm upward to release the upper roller, thereby reducing the pressure. The maximum pressure supported is 20T and the minimum pressure is 3.6T. This design can adjust the calendering pressure more flexibly to meet the needs of different fabrics and coating processes.

[0034] Furthermore, as a preferred implementation mode of the present invention but not a limitation thereof, the cylinder 5 contracts, pulling the lever arm 6 downward to increase the pressure between the upper roller 2 and the lower roller 3, and the cylinder 5 extends, pushing the lever arm 6 upward to release to reduce the pressure between the upper roller 2 and the lower roller 3.

[0035] In this embodiment, the lever arm is controlled to move up and down by the telescopic movement of the cylinder, thereby realizing the precise adjustment of the pressure between the upper roller and the lower roller. When the cylinder contracts, the lever arm presses the upper roller downward, increasing the pressure between the upper roller and the lower roller, thereby improving the calendering effect; when the cylinder extends, the lever arm releases the upper roller upward, reducing the pressure between the upper roller and the lower roller, thereby reducing the calendering pressure. This design can flexibly adjust the calendering pressure according to actual needs to obtain the desired surface finish and reflective performance of the fabric.

[0036] Furthermore, as a preferred implementation manner of the present solution but not limiting, it further includes a temperature regulating mechanism 7 connected to the upper rolling roller 2 and used for regulating the temperature of the upper rolling roller 2 .

[0037] In this embodiment, since the conventional calender in the prior art does not have a temperature regulating function, the temperature of the upper roller may be too high or too low. If the temperature of the upper roller is too high, the fabric may be thermally damaged during the calendering process, such as deformation, discoloration, embrittlement, etc., which seriously affects the physical properties and appearance quality of the fabric. At the same time, high temperature may also accelerate the wear and aging of the upper roller and shorten its service life. On the contrary, if the temperature of the upper roller is too low, the friction between the fabric and the upper roller will increase, the calendering resistance will increase, the calendering efficiency will decrease, and defects or unevenness may appear on the surface of the fabric. By providing a temperature regulating mechanism on the upper roller, the temperature of the upper roller can be accurately regulated, thereby ensuring that the fabric obtains the best surface finish and reflective performance during the calendering process. The temperature regulating mechanism can heat or cool the upper roller according to actual needs to maintain it working within a suitable temperature range.

[0038] Furthermore, as a preferred embodiment of the present scheme but not a limitation, the temperature control mechanism 7 includes a spray pipe 71 passing through the interior of the upper roller 2 along the axial direction, and a water inlet 72 and a water outlet 73 arranged at one end of the spray pipe 71, a chamber 74 is formed between the spray pipe 71 and the inner wall of the upper roller 2, and a plurality of water spray holes 75 connected to the chamber 74 are evenly opened on the spray pipe 71.

[0039] In this embodiment, by setting a spray pipe inside the upper roller, and using the chamber between the spray pipe and the inner wall of the upper roller and the water spray hole on the spray pipe, the temperature of the upper roller can be accurately adjusted. When the temperature of the upper roller needs to be lowered, cooling water can be injected into the spray pipe through the water inlet, and the cooling water enters the chamber through the water spray hole, and exchanges heat with the inner wall of the upper roller, thereby taking away the heat of the upper roller and achieving a cooling effect; when the temperature of the upper roller needs to be increased, the cooling water can be discharged through the water outlet to reduce the heat exchange, and the upper roller can be heated by other means. And the small hole can generate a certain pressure, which is convenient for uniform spraying. This design has a simple structure and is easy to operate. It can quickly and effectively adjust the temperature of the upper roller and ensure the calendering quality. A heating device, such as an electric heater or a steam heater, can also be set outside the upper roller to adjust the temperature of the upper roller by controlling the power or steam volume of the heating device.

[0040] Furthermore, as a preferred implementation mode of the present invention but not limitation, it also includes a power assembly 8 for driving the lower roller 3 to rotate, and the power assembly 8 includes a driving motor 81 and a coupling 82 respectively connecting the output end of the driving motor 81 and one end of the lower roller 3.

[0041] In this embodiment, by providing a power assembly consisting of a driving motor and a coupling to drive the lower roller to rotate, continuous calendering of the fabric can be achieved, thereby improving production efficiency. The driving motor provides power, which is transmitted to the lower roller through the coupling, so that the lower roller can rotate stably and evenly, thereby driving the fabric to maintain a stable operating speed and tension during the calendering process.

[0042] Further, as a preferred implementation mode of the present solution but not a limitation, the upper roller 2 and the lower roller 3 are arranged in a vertical direction.

[0043] In this embodiment, the vertical arrangement helps to maintain the consistency of the tension of the fabric when it passes through the calender, thereby reducing the deformation and wrinkles of the fabric and ensuring the uniformity of the calendering effect. Secondly, the vertical arrangement reduces the horizontal space occupied, making the calender more compact and suitable for use in a production environment with limited space. In addition, this arrangement also facilitates the maintenance and operation of the equipment because the vertically arranged rollers are easier to clean and replace.

[0044] Further, as a preferred embodiment of the present invention but not limiting, the upper roller 2 is a smooth roller. In this embodiment, the use of a smooth roller as the upper roller can improve the surface finish and reflective performance of the fabric. The surface of the smooth roller is smooth and flat, without obvious bumps or textures, so the surface of the fabric can be rolled into a smooth and flat state, reducing the surface roughness and defects.

[0045] Furthermore, as a preferred embodiment of the present invention but not a limitation, the lower roller 3 is a balanced roller. In this embodiment, the design of the balanced roller helps to reduce the vibration and noise of the entire calender during operation, and improves the stability of the equipment and the comfort of the operating environment. Since the balanced roller can evenly distribute the load, it helps to reduce the wear on the equipment caused by uneven load and extend the service life of the equipment. Balanced rollers usually have better thermal stability and mechanical stability, which is particularly important in the calendering process that requires precise control of temperature and pressure. The balanced roller can ensure that the contact with the upper roller 2 during the calendering process is more uniform, thereby ensuring that the pressure applied to the fabric when passing through the calender is consistent, and improving the uniformity and quality of the calendering effect.

[0046] Furthermore, as a preferred embodiment of the present invention but not a limitation, the cloth guide roller group 4 includes a first cloth guide roller 41, a second cloth guide roller 42 and a third cloth guide roller 43, the first cloth guide roller 41 is located below the lower roller 3 on the cloth feeding direction side, the second cloth guide roller 42 is located on the cloth feeding direction side of the lower roller 3, the third cloth guide roller 43 is located below the lower roller 3 on the cloth discharging direction side, and the second cloth guide roller 42 and the lower roller 3 are located at the same horizontal height.

[0047] In this embodiment, the first cloth guide roller 41, the second cloth guide roller 42 and the third cloth guide roller 43 are arranged in an orderly manner to provide a smooth guiding path for the fabric, ensuring a smooth transition of the fabric when entering and leaving the calendering area. The first cloth guide roller 41 is located below the lower roller 3, close to the side of the cloth feeding direction, which helps to initially guide the fabric into the calendering area and reduce the initial tension fluctuation of the fabric. The second cloth guide roller 42 is located on the side of the cloth feeding direction of the lower roller 3 and is at the same horizontal height as the lower roller 3, which helps to maintain the flatness and tension consistency of the fabric when passing through the lower roller 3, reducing the wrinkles and uneven tension of the fabric. The third cloth guide roller 43 is located below the lower roller 3, close to the side of the cloth exiting direction, which helps to guide the fabric to smoothly leave the calendering area and ensure that the tension and flatness of the fabric are maintained after calendering.

[0048] Furthermore, as a preferred implementation manner of the present solution but not limiting, it also includes water retaining plates 9 respectively provided at both ends of the upper rolling roller 2 .

[0049] In this embodiment, water baffles are provided at both ends of the upper roller to effectively prevent cooling water or other liquids from splashing or overflowing during the calendering process, thereby avoiding pollution or damage to the equipment and the working environment. The water baffles can block the splashing and overflow of the liquid, so that it can be controlled and recovered within the range of the upper roller, thereby keeping the equipment and the environment clean and safe.

[0050] Furthermore, as a preferred implementation mode of the present invention but not limiting, it also includes a protective cover 10 sleeved on the outside of the coupling 82 .

[0051] In this embodiment, physical protection is provided for the coupling and its connected parts to prevent accidental collision or damage by foreign objects that may occur during the production process, thereby ensuring the normal operation of the coupling and extending its service life. In addition, the protective cover 10 can prevent operators from contacting high-speed rotating or moving coupling parts, reduce safety risks in the workplace, and ensure the safety of operators.

[0052] The working principle of this embodiment is as follows:

[0053] The present invention discloses a pressure-adjustable calender, which realizes precise control of the calendering pressure by arranging an upper roller and a lower roller on a frame and adjusting the pressure of the upper roller using a combined structure of a cylinder and a lever arm. Compared with the traditional solid roller extrusion method, this scheme has a wider pressure adjustment range and can meet the requirements of different fabrics and coating processes.

Any method structure similar to the present application, or some technical deductions or replacements made based on the concept of the present application, shall be deemed to be within the protection scope of this application.
