Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.
As shown in fig. 1-3, a high-density board pre-pressing adjusting mechanism comprises a frame 1, wherein two sides of the middle part of the frame 1 are respectively hinged with one end of a hinged frame 2, the other end of each hinged frame 2 is hinged with a piston rod end of a lifting hydraulic cylinder 3, the bottom end of the lifting hydraulic cylinder 3 is hinged at the upper part of the frame 1, the lifting hydraulic cylinder 3 is connected with a hydraulic station through a pipeline, the hydraulic station provides power for the lifting hydraulic cylinder 3, and the lifting hydraulic cylinder 3 can drive an upper pressing roller 4 to lift or lower through work.
The two upper press rolls 4 are respectively arranged on the hinged frame 2 through bearings, an upper press roll gear 5 is coaxially fixed with the upper press rolls 4, two lower press rolls 6 arranged at the lower part of the frame 1 are vertically corresponding to the two upper press rolls 4, a press gap 16 is reserved, and a lower press roll gear 7 is coaxially fixed with the lower press rolls 6. The two lower press roller gears 7 and the two upper press roller gears 5 are not meshed for transmission.
The motor 14 and the speed reducer 15 are fixed on the motor support 17, the motor 14 is connected with the transmission shaft 8 through the speed reducer 15 and the coupler, the transmission gear 9 is arranged on the transmission shaft 8 and is meshed with the two lower squeeze roller gears 7 for transmission, the bottoms of the two pairs of lower connecting arms 12 are arranged on the transmission shaft 8 through bearings, the tops of the two pairs of lower connecting arms 12 are provided with the guide shafts 10 through bearings, the bottoms of the two pairs of upper connecting arms 13 are arranged on the guide shafts 10 through bearings, the top ends of the two pairs of upper connecting arms 13 are arranged on the shaft of the upper squeeze roller 4 through bearings, and the guide gear 11 is fixed on the guide shafts 10 and is meshed with the transmission gear 9 and the upper squeeze roller gears 5 for transmission. Namely, the motor 14 directly drives the two lower squeeze roller gears 7 to synchronously drive through the speed reducer 15, the transmission shaft 8 and the transmission gear 9.
