In addition, since the screening machine operates 24 hours a day, the time for maintenance and replacement is extremely tight. Utility Model Content

[0003] In view of this, the utility model aims to provide a screen roller and a screening machine that are easy to install, so as to solve the problem that the existing screen roller is heavy and takes a long time to repair and replace.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A sieve roller which is easy to install comprises a core shaft, a left-end fixed disk, a right-end fixed disk and a roller, wherein the core shaft is installed at the center of the roller, and the two ends of the core shaft are respectively fixed by the left-end fixed disk and the right-end fixed disk, and the left-end fixed disk and the right-end fixed disk are both detachably connected to the roller.

[0006] Furthermore, a support plate for supporting the roller is installed on the core shaft.

[0007] Furthermore, a plurality of support plates are evenly mounted on the core shaft.

[0008] Furthermore, the support plate is connected to the roller in the circumferential direction by using a concave-convex matching structure.

[0009] Furthermore, the right-end fixing plate is connected to the roller via a right-end gland, and a hexagon socket head screw is provided at the connection between the right-end gland and the roller.

[0010] Furthermore, the roller is made of non-metallic polymer material.

[0011] Furthermore, the inner hole of the roller is provided with convex ribs made of polymer material.

[0012] Furthermore, a screening machine includes a screening roller that is easy to install.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The roller of the utility model adopts non-metallic polymer material, which reduces the weight of the screen roller and makes it more convenient to replace the screen roller. Timely replacement of the screen roller ensures that the diameter of the pellets is within a reasonable range, thereby reducing the production cost of the product and improving the market competitiveness of the product.

[0015] 2. The mandrel and the roller of the utility model are fixed by a left-end fixing plate and a right-end fixing plate, and the right-end fixing plate is also connected by a right-end pressure cover and a hexagon socket head screw, so that the roller and the mandrel can be quickly installed, thereby facilitating the replacement of the mandrel and the roller.
