[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Referring to the accompanying drawings: the cylinder cover flipping mechanism of the wet granulator comprises a material cylinder 1 and a cylinder cover 2 covering the material cylinder 1, a cylinder cover support rod 21 is arranged on the cylinder cover 2, a cylinder cover circumferential rotating shaft 3 is arranged on one side of the cylinder cover support rod 21, a first cylinder support 4 is arranged at the upper end of the cylinder cover circumferential rotating shaft 3 to rotate with the rotation of the cylinder cover and to install the first cylinder 41, and a second cylinder support 8 is arranged at the lower end to drive the cylinder cover circumferential rotating shaft 3 to rotate and to install the second cylinder 81, and the upper end of the first cylinder support 4 is arranged There is a shaft bracket 5 for installing a flip shaft 51, one end of the flip shaft 51 is connected to the output shaft of the first cylinder 41 through a swing arm 6, and the other end is connected to the sleeve 21-a arranged on the cylinder head support rod 21. The swing arm 6 includes a shaft connecting part 61 connected to the flip shaft 51, and a cylinder connecting part 62 connected to the output shaft of the first cylinder 41. The shaft connecting part 61 and the cylinder connecting part 62 are assembled and matched, and a locking structure 7 is arranged between the two to prevent the two from being separated during the non-maintenance stage. The principle of the utility model is that the cylinder head circumferential rotating shaft 3 is driven to rotate by the second cylinder 81, and the second cylinder 81 is arranged horizontally and the cylinder head circumferential rotating shaft 3 is arranged vertically. The output shaft of the second cylinder 81 is hinged with a connecting seat arranged on the cylinder head circumferential rotating shaft 3, so that the second cylinder 81 can drive the cylinder head circumferential rotating shaft 3 to rotate when outputting, so that the cylinder head 2 can be translated to one side, that is, the positioning edge of the cylinder head 2 is separated from the retaining edge of the material cylinder 1, and then the first cylinder 41 is used to drive the flip shaft 51 after separation, and the first cylinder 41 is arranged vertically and the flip shaft 51 is arranged horizontally, and the connecting part of the flip shaft 51 and the swing arm 6, and the connecting part of the shaft sleeve 21-a are all rectangular. The rotating shaft 51 will not rotate on its own, but it can directly transmit the force of rotation to the cylinder head support rod 21, so as to realize the flipping of the cylinder head 2. This method replaces the manual drive method and improves the efficiency of opening the cover. At the same time, the swing arm 6 used to connect the first cylinder 41 and the flipping shaft 51 is assembled, that is, it has two parts: a shaft connection part 61 and a cylinder connection part 62. This arrangement is for the convenience of subsequent maintenance. When it is necessary to maintain the flipping shaft 51 or the first cylinder 41, it is only necessary to release the lock of the locking structure 7 to realize the detachment of the shaft connection part 61 and the cylinder connection part 62, so that there is no need to release the connection between the swing arm 6 and the first cylinder 41, and the connection between the swing arm 6 and the flipping shaft 51, thereby improving convenience.

[0022] The cylinder connection part 62 has an assembly base surface 62-a, and a positioning block 62-a1 is arranged on the assembly base surface 62-a. The shaft connection part 61 has an assembly mating surface 61-a in contact with the assembly base surface 62-a. The assembly mating surface 61-a is provided with a positioning slot 61-a1 for limiting the final assembly position of the cylinder connection part 62 on the shaft connection part 61. The positioning block 62-a1 is inserted into the positioning slot 61-a1 along the assembly direction. The cylinder connection part 62 and the shaft connection part 61 are assembled and matched by using the positioning block 62-a1 and the positioning slot 61-a1, and the positioning block The block 62-a1 and the positioning slot 61-a1 can produce a tight fit after being matched, so that the state presented after assembly can be maintained when not locked by the locking structure 7, and the subsequent operation of the locking structure 7 will not affect the integrity. The assembly base surface 62-a and the assembly matching surface 61-a are both planes, so that the assembly base surface 62-a and the assembly matching surface 61-a of the cylinder connecting part 62 and the rotating shaft connecting part 61 can be assembled together after assembly, and there is no matching gap, so that the swing arm 6 will not affect the overall structural stability of the swing arm 6 when driving the flip shaft 51 to rotate.

[0023] Both the assembly base surface 62-a and the assembly mating surface 61-a have a step configuration, that is, the assembly base surface 62-a has a step configuration that is concave at the top and convex at the bottom, and the assembly mating surface 61-a has a step configuration that is convex at the top and concave at the bottom. In this way, when the two need to be separated, the articulated swing of the first cylinder 41 can be utilized to make the cylinder connecting part 62 swing upward, and the convex part (also including the positioning plug 62-a1) can be utilized to contact the convex part of the assembly mating surface 61-a, thereby achieving separation of the two by pushing up, so that no interference will occur.

[0024] The cylinder connection part 62 has a first assembly top 62-b and a first assembly bottom 62-c, the shaft connection part 61 has a second assembly top 61-b and a second assembly bottom 61-c, the locking structure 7 includes a locking arm 71 and a locked column 72, the first assembly top 62-b and the first assembly bottom 62-c are both provided with the locking arm 71, the second assembly top 61-b and the second assembly bottom 61-c are both provided with the locked column 72, one end of the locking arm 71 is swingably connected to the first assembly top 62-b, the first assembly bottom 62-c, and the other end A locking socket 71-a combined with the locked column 72 is provided. There are two locking structures 7, which act on the upper end and the lower end of the swing arm 6 respectively, so that the swing arm 6 has upper end constraints and lower end constraints. In this way, the swing arm 6 is sandwiched in the middle by the two locking structures 7, so that the swing arm 6 will not be out of assembly when swinging, and the locking structure 7 is easy to cooperate, that is, by swinging the locking arm 71, the locked column 72 enters the locking socket 71-a, so as to prevent the locking arm 71 from swinging, thereby maintaining the locking state of the locking structure 7.

[0025] A self-locking plate 72-a is provided at the upper end of the locked column 72, that is, the self-locking plate 72-a is used to constrain the upper end of the locked column 72, and the distance between the bottom surface of the self-locking plate 72 and the second assembly upper surface 61-b or the second assembly lower surface 61-c is smaller than the thickness of the locking arm 71. In this way, the locking arm 71 can also contact the self-locking plate 72-a while combining with the locked column 72, and the contact can generate a squeezing force, thereby increasing the resistance of the locking arm 71 when it is combined with the locked column 72. Similarly, the resistance of the locking arm 71 when it is withdrawn is also increased, thereby maintaining the locked state of the locking structure 7 and preventing the locking arm 71 from withdrawing by itself.

[0026] An axle seat 21-b connected to the shaft sleeve 21-a is arranged at the center position of the cylinder head support rod 21. The axle seat 21-b provides lateral support for the shaft sleeve 21-a, that is, it also provides lateral support for the flip shaft 51, which can reduce the stress of the flip shaft 51 when driving the cylinder head 2 to flip, and avoid damage to the flip shaft 51.

[0027] A counterweight 21-c is provided at the end of the cylinder head support rod 21 which is not provided on the cylinder head 2. The counterweight 21-c is used to increase the stability of the cylinder head 2 when it is closed, and on the other hand, it can improve the efficiency of opening or closing the cover. That is, when the cylinder head 2 is opened and flipped, the counterweight 21-c makes it possible for the cylinder head 2 to no longer require the driving force of the first cylinder 41 after it is opened to a certain angle, that is, the cylinder head 2 can flip itself to the desired opening angle by its own weight. Similarly, when the cover is closed, the cylinder head 2 can flip itself to the closed state by its own weight.

[0028] A first shaft cylinder 31 and a second shaft cylinder 32 connected to the first shaft cylinder 31 are mounted on the cylinder head circumferential rotating shaft 3. The first cylinder bracket 4 is fixed on the outer circumferential surface of the first shaft cylinder 31. The first shaft cylinder 31 and the second shaft cylinder 32 can increase the rotation stability of the cylinder head circumferential rotating shaft 3, and the first shaft cylinder 31 can also be connected to the first cylinder bracket 4.

[0029] The lower end of the cylinder head circumferential rotating axis 3 is provided with a third cylinder bracket 9 located below the second cylinder bracket 8 and used to install the third cylinder 91. The third cylinder 9 is used to drive the cylinder head circumferential rotating axis 3 to move upward, so that the positioning edge of the cylinder head 2 is separated from the retaining edge of the material cylinder 1. This can avoid the positioning edge and the retaining edge from being scratched when the cylinder head 2 is translated under the drive of the second cylinder 81.

[0030] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
