[0011] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further explained in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0012] DETAILED DESCRIPTION: in combination Figs. 1-2 As shown in the figure, a rubber breaker comprises a frame 1, the frame 1 is provided with a fixed roller 2, the interior of the fixed roller 2 is a cylindrical cavity, the top of one side of the fixed roller 2 is provided with a feeding port 21, the bottom of the other side of the fixed roller 2 is provided with a discharging port 22, a conical roller 3 is rotationally connected in the fixed roller 2, the conical roller 3 is in transmission connection with a motor 4, the diameter of the conical roller 3 gradually increases from one end close to the feeding port 21 to one end close to the discharging port 22, so that the gap between the conical roller 3 and the inner wall of the fixed roller 2 gradually decreases, a plurality of spiral bevel gears are arranged outside the conical roller 3, the side of the spiral bevel gears away from the conical roller 3 is close to the inner wall of the fixed roller 2, the spiral bevel gears can push the rubber block to the end where the discharging port 22 is located when the conical roller 3 rotates, and the rubber block is gradually ground in the process and the ground rubber powder is discharged from the discharging port 22, the interior of the conical roller 3 is a cavity and both ends of the conical roller 3 are provided with shaft tubes in communication with the interior cavity of the conical roller 3, the two shaft tubes extend from both ends of the fixed roller 2 respectively, at least one of the shaft tubes is provided with a plurality of blades 31 for generating airflow, the blades 31 are inclined to the axis of the shaft tube, the blades 31 will rotate with the shaft tube when the conical roller 3 rotates, so that the airflow flowing through the conical roller 3 is generated to cool the conical roller 3. A belt pulley can be arranged outside one of the shaft tubes, a belt pulley is also arranged on the rotating shaft of the motor 4, the two belt pulleys are in transmission connection by a belt, so that the motor 4 can drive the conical roller 3 to rotate.

[0013] The inner cavity of the conical roller 3 is provided with a flow distribution cone 32, which is fixed in the inner cavity of the conical roller 3 through a supporting sheet, both ends of the flow distribution cone 32 are conical and coaxial with the shaft cylinder, so that the airflow can flow along the inner wall of the conical roller 3, and the cooling effect is better.

[0014] The flow distribution cone 32 is a hollow structure, which reduces the weight.

[0015] The glue breaking machine of the present application uses airflow for cooling, so there is no problem of water leakage, and no additional funds are spent to purchase a cooling water circulating device.

[0016] The embodiments of the specific embodiment are the preferred embodiments of the utility model, and are not limited to the protection scope of the utility model, so that: any equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
