[0002] A calender consists of two or more rollers arranged according to the heating method. They can be categorized as cold pressing or hot pressing. Cold pressing is suitable for materials that don't require heating, such as graphite film, graphite sheets, absorbing materials, shielding materials, magnetic materials, and non-ferrous metals. Hot pressing can be further categorized as water-heated, electric-heated, oil-heated, or electromagnetic-heated. All of these machines press and stretch materials such as rubber, silicone, silicone rubber, phase-change materials, PTFE, or plastics into sheets of a specific thickness and surface shape at a specific temperature. They can also coat fiber cords, canvas, or steel cords with glue.

[0003] The calender in the prior art adopts a roller height-adjustable structure to adapt to a variety of raw materials of different thicknesses, thereby increasing the scope of application of the calender. However, the height of the calender with this structure is fixed and cannot be changed during the operation of the calender. When the thickness of the raw materials is uneven, the raw materials at thinner positions cannot contact the rollers, resulting in inconsistent surface flatness of the products, thereby producing a large number of defective products, wasting raw materials, and reducing the calendering quality.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] See also Figure 1-6The utility model provides an embodiment: an adaptive thickness calender, comprising a machine body 1, a square calendering chamber 2 is opened on one side of the machine body 1, and side grooves 3 are opened on the inner walls on both sides of the calendering chamber 2. The side grooves 3 are vertical grooves, and guide cylinders 4 are fixedly installed in the side grooves 3 on both sides. The guide cylinders 4 are hollow structured, and telescopic rods 5 are fixedly installed on the inner walls of the upper and lower ends of the two guide cylinders 4. The bottom end of the telescopic rod 5 is fixedly installed with a sliding seat 6, and the sliding seat 6 is slidably connected to the guide cylinder 4. A cylindrical spring 7 is fixedly installed on the outer surface of the sliding seat 6, and the cylindrical spring 7 is sleeved on the outside of the telescopic rod 5. An upper rotating shaft 8 is rotatably installed between the two opposite sliding seats 6 at the upper end, and a lower rotating shaft 9 is rotatably installed between the two opposite sliding seats 6 at the lower end.

[0026] Furthermore, an upper calendering roller 10 is fixedly mounted on the upper rotating shaft 8, and a lower calendering roller 11 is fixedly mounted on the lower rotating shaft 9;

[0027] According to the above structure, when the present invention is calendering raw materials with uneven thickness, the raw materials can enter between the upper calendering roller 10 and the lower calendering roller 11, so that the upper and lower outer surfaces of the raw materials are in contact with the upper calendering roller 10 and the lower calendering roller 11 respectively, ensuring normal calendering work;

[0028] When the thicker portion of the raw material enters between the upper calendering roller 10 and the lower calendering roller 11, due to the problem of increased thickness of the raw material, it will push against the upper calendering roller 10 and the lower calendering roller 11, thereby increasing the distance between the upper calendering roller 10 and the lower calendering roller 11. In the process of increasing the distance between the calendering rollers, the upper and lower sets of sliding seats 6 at both ends of the rollers move upward and downward due to the increase in thickness. In the process of moving the sliding seat 6, it compresses the cylindrical spring 7 on the outer surface, thereby causing the cylindrical spring 7 to undergo elastic deformation of compression. In this way, the pressure between the calendering rollers can be increased through the compression resilience of the cylindrical spring 7, thereby ensuring that the thicker portion can be smoothly calendered.

[0029] When the raw material is continuously fed and calendered, due to the uneven thickness of the material, its thickness will change from thick to thin. In the process of changing from thick to thin, the compressed cylindrical spring 7 can extend and reset to a certain extent by relying on its own elasticity. At this time, the compression spring 7 can drive the upper calendering roller 10 and the lower calendering roller 11 to move similarly. Even if the distance between the upper calendering roller 10 and the lower calendering roller 11 becomes smaller, the upper calendering roller 10 and the lower calendering roller 11 with the smaller distance can continue to fully contact the thinner part of the material, thereby ensuring a normal contact calendering effect.

[0030] The telescopic rod 5 is provided so that it can extend or retract along with the cylindrical spring 7 when it undergoes elastic deformation. Thus, the synchronous extension and contraction of the telescopic rod 5 can provide a certain degree of telescopic guidance for the deformation process of the cylindrical spring 7, thereby preventing the cylindrical spring 7 from tilting during deformation, and allowing the cylindrical spring 7 to always maintain a linear telescopic deformation state, thereby ensuring the stability of the cylindrical spring 7 during use.

[0031] In this embodiment, an inspection panel 12 is located directly below the rolling chamber 2 and is hinged on the machine body 1. A handle is fixedly installed on the inspection panel 12. The machine body 1 can be opened through the inspection panel 12, thereby facilitating the inspection and maintenance of the electrical structure inside the machine body 1.

[0032] In this embodiment, a working status indicator light 13 is fixedly mounted on the outer wall of one side of the body 1. There are three working status indicator lights 13. The colors of the three working status indicator lights 13 are red, yellow and green from bottom to top.

[0033] Furthermore, in order to give an alarm for abnormal processing conditions of the machine body 1 , an alarm light 15 is fixedly mounted on the top outer wall of the machine body 1 away from the working status indicator light 13 by fixing bolts.

[0034] In this embodiment, in order to facilitate the overall programming or setting of the calender of the present invention, a control panel 14 is fixedly installed on the outer wall of the front side of the body 1, and the control panel 14 is provided with a display screen and several physical buttons.

[0035] In this embodiment, a ventilation plate is fixedly installed on the body 1 below the control panel 14. The ventilation plate is provided with a plurality of ventilation slots. The ventilation plate ensures normal circulation between the electrical equipment inside the body 1 and the outside air, thereby ensuring heat dissipation.

[0036] In order to improve the bottom support stability of the body 1, support feet are fixedly installed at the four corners of the bottom end of the body 1.

[0037] Working principle: When the thicker part of the raw material enters between the upper calendering roller 10 and the lower calendering roller 11, due to the problem of increased thickness of the raw material, it will push against the upper calendering roller 10 and the lower calendering roller 11, thereby increasing the distance between the upper calendering roller 10 and the lower calendering roller 11. In the process of increasing the distance between the calendering rollers, the upper and lower sets of sliding seats 6 at both ends of the rollers move upward and downward due to the increase in thickness. In the process of moving the sliding seat 6, it compresses the cylindrical spring 7 on the outer surface, thereby causing the cylindrical spring 7 to undergo elastic deformation of compression. In this way, the pressure between the calendering rollers can be increased through the compression resilience of the cylindrical spring 7, thereby ensuring that the thicker part can be smoothly calendered.

[0038] When the raw material is continuously fed and calendered, due to the uneven thickness of the material, its thickness will change from thick to thin. In the process of changing from thick to thin, the compressed cylindrical spring 7 can extend and reset to a certain extent by relying on its own elasticity. At this time, the compression spring 7 can drive the upper calendering roller 10 and the lower calendering roller 11 to move similarly. Even if the distance between the upper calendering roller 10 and the lower calendering roller 11 becomes smaller, the upper calendering roller 10 and the lower calendering roller 11 with the smaller distance can continue to fully contact the thinner part of the material, thereby ensuring a normal contact calendering effect.

[0039] The utility model can drive the two sets of calendering rollers to adjust the free spacing during calendering through the free elasticity of the spring, so that the utility model can freely adjust the spring expansion and contraction under the resistance of different thicknesses of raw materials. It has the technical characteristics of free adjustment of the spacing during the working process and has a good material thickness self-adaptive use effect, which can ensure that the two sets of rollers are always in calendering contact with the calendering material, thereby ensuring normal processing quality.

[0040] The telescopic rod 5 is provided so that it can extend or retract along with the cylindrical spring 7 when it undergoes elastic deformation. Thus, the synchronous extension and contraction of the telescopic rod 5 can provide a certain degree of telescopic guidance for the deformation process of the cylindrical spring 7, thereby preventing the cylindrical spring 7 from tilting during deformation, and allowing the cylindrical spring 7 to always maintain a linear telescopic deformation state, thereby ensuring the stability of the cylindrical spring 7 during use.

[0041] To sum up, the calender of the present invention is designed with a spring compression and self-resetting elastic structure, so that the distance between the two sets of calendering rollers can be dynamically changed during actual use, and the elastic free distance adjustment can be performed according to the thickness of different materials. Therefore, it is suitable for calendering raw materials with uneven thickness. The elastic compression between the rollers can always maintain contact with the outer surface of the material, thereby achieving consistent calendering flatness performance, greatly improving the scope of application of the present invention, with strong calendering uniformity, simple overall structure, low manufacturing and maintenance costs, and suitable for popularization and use.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
