Description

Technical Field

[0001] The utility model relates to the technical field of calenders, in particular to a rubber calender for calendering rubber into sheets by mixing rubber. Background Art

[0002] Rubber calenders are essential equipment in the processing of rubber and plastic products. Among rubber and plastic machinery, calenders are heavy-duty, high-precision machines. They are primarily used for sheeting rubber, coating textiles or steel cord with rubber, laminating rubber sheets, profiling rubber blanks, and applying separators to tire cord plies. The rubber passes through the gap between two or more rotating rollers maintained at a specific temperature and speed. Under the pressure of the rollers, the rubber stretches and thins, enabling sheeting and lamination. During the calendering process, parameters such as roller temperature, speed, speed ratio, and roll gap significantly influence the calendering effect. For example, a higher temperature reduces the viscosity of the rubber, making it easier to flow and deform; an appropriate speed and speed ratio ensure uniform calendering of the rubber; and a reasonable roll gap determines the thickness and dimensional accuracy of the calendered rubber.

[0003] Current calenders on the market suffer from low calendering precision, high consumption, and improper roller spacing, which can cause uneven stretching and squeezing of the rubber between the rollers, affecting the uniformity of product thickness and width. The roller spacing adjustment accuracy is also low, affecting calendering thickness and precision. The mechanical transmission accuracy and clearance of the machine also affect calendering precision.

[0016] The following is a further description of the specific embodiments of the present invention with reference to the accompanying drawings:

[0017] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0019] like Figure 1 As shown, the present invention discloses a rubber calender, which includes a motor 1, a gearbox 2, a transmission gearbox 3, and a calendering roller. The motor 1 inputs power to the gearbox 2, which transmits the power to the calendering roller through the transmission gearbox 3. The motor 1 and gearbox 2 are vertically mounted, with the motor 1 mounted above the gearbox 2. This vertical installation of the motor 1 and gearbox 2 can significantly save space on the calender and improve factory utilization. In addition, because the transmission gears of the gearbox 2 are mostly horizontal, it is easier to start and has a higher kinetic energy conversion ratio.

[0020] As a preferred embodiment, the calendering rollers include a driving roller 4 and a driven roller 5. A servo motor 6 is installed in the calender body to adjust the gap between the driving roller 4 and the driven roller 5. Two servo motors 6 are installed at the top of the calender body, connecting the two ends of the driven roller 5 to adjust the gap between the driving roller 4 and the driven roller 5. The use of servo motors 6 offers high adjustment precision and easier control, significantly improving the accuracy of sheet discharge from the calender.

[0021] The active roller 4 and the driven roller 5 are provided with cooling water channels, a cooling cavity is provided in the roller, and an external water pump is connected. This circulating cooling allows the rubber sheet to be heated evenly, making it easier to calender the rubber.

[0022] A support roller 7 is installed outside the calendering roller at the sheet discharge position. A rubber sheet cutting device 8 is mounted on the calender body above the support roller 7. The rubber sheet cutting device 8 is mounted on a transverse adjustment device 9. The transverse adjustment device 9 includes two sliding rods, a mounting seat, and an adjustment screw mounted on the body. The mounting seat is mounted on the rubber sheet cutting device 8, and the mounting seat 10 is sleeved on the sliding rod. One end of the adjustment screw is mounted on the body frame via a bearing, and a rotating handle is installed at the end. The other end of the adjustment screw is connected to the mounting seat 10. The rotating handle drives the screw to rotate, thereby adjusting the cutting width of the rubber sheet cutting device of the mounting seat. This structure of the transverse adjustment device is very convenient for adjusting the width of the rubber sheet slice.

[0023] The rubber sheet cutting device 8 comprises a cylinder and a cutting knife, and the cutting knife is installed on the output shaft of the cylinder.

[0024] In short, the calender of the utility model has a reasonable structure and layout, occupies a small area, is easy to adjust, is energy-saving and efficient, and has high sheet output precision, and can meet the requirements of high-precision rubber sheet output.
