[0014] (2) In the papermaking water-saving circulating spray device, when the transmission rod 2 rotates, the elastic cam can be driven to rotate, which in turn knocks on the filter frame and causes it to vibrate. Under the action of centripetal force, the gravity column inside the elastic cam squeezes the power rod, causing it to move and move out of the elastic cam. When the elastic cam hits the filter frame, the power rod is squeezed by the filter frame and hits the gravity column in the reverse direction, causing the gravity column to hit the inner wall of the fixed groove away from the power rod. In this case, the elastic cam vibrates in the reverse direction, so that the filter frame vibrates in two different directions during the knocking process, further improving the cleaning effect of the device.

When the transmission rod 805 rotates, the elastic cam 901 fixedly connected to the transmission rod 805 can be driven to rotate. During the rotation, the elastic cam 901 will knock on the filter frame 700 in turn and cause it to vibrate. Under the action of centripetal force, during the rotation of the elastic cam 901, the gravity column 905 inside it squeezes the power rod 904, causing it to move and move out of the elastic cam 901. When the elastic cam 901 hits the filter frame 700, the power rod 904 is squeezed by the filter frame 700 and hits the gravity column 905 in the reverse direction, causing the gravity column 905 to hit the inner wall of the fixed groove 902 away from the power rod 904. As a result, the elastic cam 901 vibrates in the opposite direction in this case, so that the filter frame 700 vibrates in two different directions during the knocking process, further improving the cleaning effect of the device.

[0036] When in use, when the transmission rod 805 rotates, the elastic cam 901 fixedly connected to the transmission rod 805 can be driven to rotate. During the rotation process, the elastic cam 901 will knock on the filter frame 700 in turn and cause it to vibrate. Under the action of centripetal force, during the rotation process, the gravity column 905 inside the elastic cam 901 squeezes the power rod 904, causing it to move and move out of the elastic cam 901. When the elastic cam 901 hits the filter frame 700, the power rod 904 is squeezed by the filter frame 700 and hits the gravity column 905 in the reverse direction, causing the gravity column 905 to hit the inner wall of the fixed groove 902 away from the power rod 904, thereby causing the elastic cam 901 to vibrate in the opposite direction, thereby causing the filter frame 700 to vibrate in two different directions during the knocking process.
