Embodiment Construction
[0011] The safety protection device in the open mill of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.
[0012] see figure 1 , figure 2 , image 3 As shown, the safety protection device in the mill of the present invention is respectively provided with a set of safety ram device at the front and rear sides of the mill roller 10, that is, the front safety ram device and the front safety ram device positioned at the front side of the roller. Be positioned at the rear safety ram device of roller rear side---in the present embodiment, the previous safety ram device is described as an example, and the structure of the rear safety ram device is the same as that of the front safety ram device, so no more details are given. The structure of the front safety ram device is: the ram 1 positioned outside the roller 10, the ram 1 is articulated on the support 12 of the open mill through a pair of cantilevers...

The invention discloses a safety protection device for an open mill. A safe collision rod device is arranged at the front side and rear side of a roller of the open mill respectively. The structure of the safe collision rod device is as follows: the safe collision rod device comprises a collision rod located outside the roller, the collision rod is movably hung on a stand of the open mill through a pair of cantilevers, the collision rod can swing around hanging points of the cantilevers and the stand, at least one travel switch is further arranged on the stand, and the collision rod can collide with a touch handle of the travel switch when the collision rod swings inward; and limiting devices for preventing the collision rod from mistakenly colliding with the touch handle of the travel switch are further arranged on the stand. With the adoption of the safety protection device for the open mill, disclosed by the invention, the roller of the open mill can immediately stop working so long as an operator collides with the collision rod consciously or unconsciously and the collision rod then collides with the touch handle, so that the danger that the operator is injured by the roller due to rolling or scalding is accordingly avoided, and the operational safety is improved.
Description
technical field [0001] The invention relates to an open mill for refining rubber, in particular to a safety protection device in the open mill. Background technique [0002] When the mill is working normally, in order to prevent the operator from being accidentally injured by the roller in the mill, a safety protection device that can make the emergency stop of the roller is usually provided with in the mill. The safety protection device of the mill commonly used at present is: an emergency pull wire switch is arranged above the roller. When encountering an emergency, or when the operator needs to operate close to the roller, the operator needs to pull the switch to make the control device in the mill cut off the power supply of the motor driving the roller; after the emergency is lifted or the operation is completed, The switch needs to be pulled a second time to allow the control to restore power to the roller motor. The disadvantages of the safety protection device in t...
