Description

Technical Field

[0001] The utility model relates to the field of rubber processing and production, in particular to a rubber raw material calender. Background Art

[0002] Rubber processing is the process of making rubber into rubber products. The basic processes of various rubber product processing include plasticizing, mixing, calendering or extrusion (i.e. extrusion), molding and vulcanization. Each process has different requirements for the product and is combined with a number of auxiliary operations.

[0003] After searching, a Chinese patent application with publication number CN212684507U discloses a rubber material calendering mechanism. The rubber material calendering mechanism comprises: a power box; a left side plate and a right side plate, the bottom ends of which are fixedly connected to the top and sides of the power box, respectively, and each of which has a movable hole; a lower pressure roller, the axis of which is rotatably connected to the right bottom of the left side plate via a lower rotating shaft; an upper pressure roller, the axis of which is disposed within the two movable holes via an upper rotating shaft; two adjustment assemblies, which are disposed on either side of the surface of the upper rotating shaft and are located on opposite sides of the left and right sides of the plate; a speed change assembly, which is disposed on the right side of the bottom inner wall of the power box; and a transmission assembly, which is disposed between the output end of the speed change assembly and the right end of the lower rotating shaft. The rubber material calendering mechanism provided by this utility model has speed change and thickness adjustment functions.

[0004] Although the above solution can adjust the thickness of the rubber, there are still some shortcomings in actual use. For example, it is inconvenient to push the rubber raw material during use, which causes the rubber raw material to slip easily between the two pressing rollers during use, so that the rubber raw material is difficult to move downward during the calendering process, affecting the calendering efficiency of the rubber.

[0005] Therefore, we propose a rubber raw material calender to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This device is equipped with a motor to provide power to the pressure roller, so that the pressure roller can calender the raw material while rotating, and by starting the cooperation of the second motor and the rotating rod, the eccentric wheel can be rotated, so that the eccentric wheel pushes the push plate and the top plate to move downward, pushing the rubber raw material into between the two pressure rollers, ensuring that the pressure roller can calender the rubber raw material, thereby preventing the rubber raw material from having difficulty in moving downward, and ensuring the calendering efficiency of the rubber raw material.

[0016] This device can guide the push plate by providing a slide groove and a slider, so that the push plate is more stable during movement, avoiding tilting and dislocation.
