DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings.
[0022] The same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "head", "tail", "top", "bottom", "left", "right", "front", "back", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0023] See also Figure 1An embodiment of the utility model provides a new type of adjustment mechanism for the roller of a double-roll crusher, comprising a fixed frame 1, a fixed-end bearing seat 2 arranged on the fixed frame 1 for installing a fixed roller 10, an adjustable-end bearing seat 3 movably arranged on the fixed frame 1 for installing an adjustable roller 11, a fixed rod 4 detachably inserted on the right side of the fixed frame 1 and arranged along the transverse direction, a pressing plate 5 sleeved on the fixed rod 4, at least an elastic fastening device 6 movably inserted on the right side of the fixed frame 1 and arranged along the transverse direction, at least one elastic member 7 arranged between the adjustable-end bearing seat 3 and the pressing plate 5 along the transverse direction, a left pad 8 detachably arranged on the left side of the fixed-end bearing seat 2, and a left fastening device 9 detachably arranged on the left side of the fixed frame 1, wherein the left end of the adjustable fastening device abuts against the pressing plate 5, and the fixed rod 4 passes through the right side of the adjustable-end bearing seat 3.
[0024] When designing a crusher, the maximum force that will cause damage to the crusher is calculated according to the working conditions, and the adjustment elastic member 7 with the corresponding elastic coefficient is selected based on this. During the installation of the crusher, a torque wrench is used to tighten the elastic fastening device 6 to the corresponding torque. At this time, the elastic member 7 is applied with a corresponding pre-tightening force to support the adjustment end bearing seat 3.
[0025] When the crusher starts working, the fixed roller 10 and the adjusting roller 11 start to rotate and work, and the material is crushed by the two rollers and then discharged. Under normal working conditions, the gap between the two rollers remains unchanged. When larger and harder particles appear in the material and the two rollers cannot crush the material, the rollers are subjected to the same reaction force while the material is being squeezed. When the force is greater than the preload of the spring, the spring is squeezed and shortened after being stressed. Because the adjusting end bearing can move left and right, it will squeeze the elastic member 7 to the right after being stressed. At this time, the gap between the fixed roller 10 and the adjusting roller 11 becomes larger, so that the material that cannot be crushed can pass smoothly. After the material passes, the two rollers are no longer subjected to stress. Because the elastic member 7 itself has a preload, the adjusting end bearing seat 3 will be supported by the elastic member 7 and move to the left to reset, so that the distance between the two rollers returns to normal, and the roller crusher works normally.
[0026] like Figure 1 As shown, in some embodiments, the left fastening device 9 includes a left fastening screw 901 inserted into the left side of the fixing frame 1, a left fixing block 902 detachably arranged on the fixed-end bearing seat 2, and a left fastening nut 903 sleeved on the left fastening screw 901, the left fastening screw 901 passes through the left side of the fixing frame 1, the left cushion block 8 and the left fixing block 902, the left fastening screw 901, the left fixing block 902 and the left fastening nut 903 cooperate to fix the fixed-end bearing seat 2, the fastening effect is good, and it is easy to install and disassemble, and the left side of the fixed-end bearing seat 2 is provided with a mounting groove that penetrates it axially, and the left fixing block 902 is arranged in the mounting groove.
