In addition, the features limited as "first" and "second" can explicitly or implicitly include one or more features. In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0027] In the description of the utility model, it is necessary to explain that, unless another explicit provision and limitation, the term "installation", "connection", "connect" should do the broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through the intermediate medium, can be two elements inside the communication, for the ordinary skilled in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to specific circumstances.

[0028] As Figures 1 to 4 The utility model discloses a kind of inclination angle adjusting devices of film evaporator, including rack 1, the left end of rack 1 is hinged with support 2, rack 1 and support 2 are connected by commonly used hinge piece. Film evaporator 3 is installed on support 2, and the bearing seat and evaporation cylinder body of film evaporator 3 are installed on support 2 by support frame and adjusting pad block.

[0029] Rack 1 and support 2 are equipped with inclination angle adjusting mechanism 4. Inclination angle adjusting mechanism 4 is located at the right end of rack 1. Inclination angle adjusting mechanism 4 includes mounting seat 41 fixed on rack 1, and mounting seat is fixedly connected with lifting screw 42, which extends out of support 2. Lifting screw 42 is T-shaped screw, and the T-shaped head of lifting screw 42 is connected to mounting seat 41. Lifting screw 42 is fixed, and mounting seat 41 is positioned by rack 1, so as to realize the positioning of lifting screw 42. Lifting screw 42 can be metric thread, trapezoidal thread or other form of transmission pair thread, and lifting nut 43 is a pair of transmission pair with lifting screw 42, with consistent thread form.

[0030] Lifting nut 43 is threadedly connected to lifting screw 42, and lifting nut 43 extends into pin shaft 44, which is held by the bottom of lifting nut 43. The flat wire of lifting nut 43 is located above pin shaft 44, and the flat wire is rotated by wrench to move lifting nut 43 on lifting screw. The cylindrical segment of lifting nut 43 extends into pin shaft 44, and the upper end of the cylindrical segment extends out of pin shaft 44. The cylindrical segment is gap-set with the inner wall of pin shaft 44. In order to ensure that lifting nut 43 can rotate freely, the cylindrical segment of lifting nut 43 must be gap-set with the through hole of pin shaft 44 to avoid interference between them. At the same time, in order to prevent pin shaft 44 from sliding down, pin shaft 44 is supported by the flat wire.

[0031] Pin shaft 44 is rotatably connected to welding seat 45, which is fixedly connected to support 2 to position the upper end of inclination angle adjusting mechanism 4, so that rotating lifting nut 43 can realize the rotation and lifting of support 2.

Retaining ring 46 blocks the lateral movement of pin shaft 44 to prevent pin shaft 44 from falling off welding seat 45.

[0032] The lifting screw 42 is detachably screwed with a locking cap 47, which covers the upper end of the lifting nut 43. When the lifting nut 43 does not need to be adjusted, the locking cap 47 can be screwed into the upper end of the lifting screw, and the locking cap 47 will abut against the pin shaft 44, so that the lifting nut 43 cannot move up and down, thereby ensuring the connection reliability of the whole device. When the inclination angle needs to be adjusted, the locking cap 47 needs to be removed, and then the lifting nut 43 can be rotated to continue adjusting the inclination angle.

[0033] The inclination angle adjusting device of the thin film evaporator 3 only needs to rotate the lifting nut 43 by a wrench when adjusting the inclination angle of the thin film evaporator 3, and the lifting nut 4 moves upward on the lifting screw 42, and the support 2 is synchronously lifted by the pin shaft 44 and the welding seat 45. The support descending is the same.
