Description

Technical Field

[0001] The utility model relates to the technical field of wet granulation, in particular to a cylinder cover locking mechanism of a wet granulator. Background Art

[0002] Wet granulator is used to grind wet powder into required granules, and also to crush block dry materials into required granules. The general use process of wet granulator is as follows: mix the required materials, start the machine, pour the mixed materials into the bucket, and the swinging action of the rotating drum squeezes the materials through the screen to form granules.

[0003] Public announcement number: CN209985371U discloses an explosion-proof wet granulator, including a frame and a material cylinder, wherein the material cylinder includes a cylinder body and a cylinder cover, and the cylinder cover is arranged on the cylinder body, and a limiting structure for limiting the separation of the cylinder body and the cylinder cover is arranged between the cylinder body and the cylinder cover, the limiting structure includes a rib arranged along the circumference of the cylinder body, an arc-shaped limiting piece is arranged on the cylinder cover, and a positioning edge is extended inwardly from the lower end face of the limiting piece, and the positioning edge extends to the bottom of the rib, and also includes a control structure for controlling the rotation of the cylinder cover so that the positioning edge deviates from the rib and the cylinder cover is flipped open. The cylinder cover of this wet granulator can be opened by first controlling the rotation of the cylinder cover through a control structure so that the positioning edge deviates from the retaining edge, and then the cylinder cover is flipped open, which makes the opening and closing of the cylinder cover more convenient, and limits the rotation angle of the cylinder cover through a limit rod and a limit groove structure. However, there is a defect that the limit rod and the limit groove structure only limit the rotation angle of the cylinder cover and cannot play a locking effect on the cylinder cover, because the cylinder cover will rotate autonomously under the influence of the force generated by stirring. Although the rotation amplitude is small due to the influence of its weight, it still causes the inside of the material cylinder to be not in a closed state, which causes the granulator to be unable to meet the vacuum requirements of certain polymer raw materials, and also causes some raw materials to penetrate from the gaps.

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Referring to the accompanying drawings: the cylinder cover locking mechanism of this wet granulator includes a material cylinder 1 and a cylinder cover 2 covered on 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 bracket 4 is arranged on the upper end of the cylinder cover circumferential rotating shaft 3 for mounting the first cylinder 41 through its self-rotation and a second cylinder bracket 5 is arranged on the lower end for driving the cylinder cover circumferential rotating shaft 3 to rotate and for mounting the second cylinder 51, a connecting unit 6 arranged on the cylinder cover circumferential rotating shaft 3 is hinged on the output shaft of the second cylinder 51 to drive the cylinder cover circumferential rotating shaft 3 to rotate under the execution of the second cylinder 51, a third cylinder 52 is arranged on the second cylinder bracket 5, a locking plug rod 7 is arranged on the output shaft of the third cylinder 52, and a locking socket 8 combined with the locking plug rod 7 is arranged on the connecting unit 6 to prevent the cylinder cover circumferential rotating shaft 3 from rotating when the two are combined. The principle of the utility model is that the cylinder head circumferential rotating shaft 3 is driven to rotate by the second cylinder 51, and the second cylinder 51 is arranged horizontally and the cylinder head circumferential rotating shaft 3 is arranged vertically, so that the second cylinder 81 can drive the cylinder head circumferential rotating shaft 3 to rotate when outputting, so as to realize the cylinder head 2 to translate to one side, that is, the positioning edge of the cylinder head 2 is separated from the retaining edge of the cylinder 1, and the connecting unit 6 can transmit the driving force generated by the second cylinder 51 to the cylinder head circumferential rotating shaft 3 while also being hinged to the second cylinder 51, and the hinge can increase the flexibility of use to meet the rotation change of the cylinder head circumferential rotating shaft 3, and after separation, the cylinder head 2 is driven to flip by the first cylinder 41, that is, the first cylinder 41 is connected to the flip rotating shaft arranged on the cylinder head support rod 21 through a swing arm, and the first cylinder 41 is arranged vertically and the flip rotating shaft is arranged vertically. It is arranged horizontally, so that when the first cylinder 41 is executed, the cylinder cover 2 can be driven to flip, which replaces the manual drive method and improves the efficiency of opening the cover. At the same time, a locking rod 7 and a locking hole 8 are provided to increase the closing stability of the cylinder cover 2 in the closed state. The locking rod 7 and the locking hole 8 can prevent the circumferential rotating shaft 3 of the cylinder cover from rotating after being combined. Because a certain force is generated when the raw materials are stirred inside the material cylinder 1, the material cylinder 1 itself will shake due to the force, and the cylinder cover 2 will move to one side when shaken. Although the cylinder cover 2 is affected by its own weight, the translation distance of the cylinder cover 2 is small, but it will also cause the cylinder cover 2 to be incompletely closed, that is, it cannot meet the needs of some polymer materials that need to be stirred in a vacuum environment. Therefore, this arrangement can avoid the cylinder cover 2 from moving to one side.

[0020] The connecting unit 6 includes a cylinder joint 61, an intermediate connecting block 62, and an axis fixing block 63. The cylinder joint 61 is arranged on the output shaft of the second cylinder 51. The intermediate connecting block 62 is respectively hinged to the cylinder joint 61 and plugged with the axis fixing block 63. The axis fixing block 63 is arranged on the cylinder head circumferential rotating shaft 3. The locking socket 8 is arranged on the intermediate connecting block 62. The purpose of setting the cylinder joint 61 is to enable the second cylinder 51 to have the ability to be hinged with other parts. The hinge is to increase the use flexibility of the second cylinder 61. Because the movement form of the cylinder head circumferential rotating shaft 3 is rotation, the hinge is used to adapt to the rotation change of the cylinder head circumferential rotating shaft 3. The intermediate connecting block 62 and the axis fixing block 63 are to enable the cylinder head circumferential rotating shaft 3 to have a part that can be hinged with the cylinder joint 61, and the axis fixing block 63 is fixed on the cylinder head circumferential rotating shaft 3. The intermediate connecting block 62 is simultaneously hinged with the cylinder joint 61 and plugged with the axis fixing block 63 as a connecting component.

[0021] The middle connecting block 62 includes a main body 62-a and an extension body 62-b extending from the main body 62-a. The main body 62-a is plugged into and matched with the shaft fixing block 63, and the extension body 62-b is hinged to the cylinder joint 61. In this way, the middle connecting block 62 has the ability to be plugged and assembled with the shaft fixing block 63 and to be hinged with the cylinder joint 61.

[0022] The main body 62-a is provided with a positioning rod 62-a1 extending downward, and two first bolt mounting holes 62-a2 arranged through it, and the shaft fixing block 63 is provided with a positioning hole 63-a combined with the positioning rod 62-a1, and two second bolt mounting holes 63-b matching the positions of the first bolt mounting holes 62-a2, the first bolt mounting hole 62-a2 and the corresponding second bolt mounting hole 63-b are used to set the bolts, and the locking hole 8 is provided on the main body 62-a and located at the positioning rod 62-a On one side, the final position of the intermediate connection block 62 on the shaft fixing block 63 can be quickly determined by combining the positioning plug rod 62-a1 and the positioning plug hole 63-a. The first bolt mounting hole 62-a2 and the corresponding second bolt mounting hole 63-b are used to set bolts, so that the intermediate connection block 62 can be fixed on the shaft fixing block 63, thereby preventing the intermediate connection block 62 from quickly transferring kinetic energy to the shaft fixing block 63 when the second cylinder 51 is driven to rotate the shaft, and preventing the intermediate connection block 62 from rotating under force.

[0023] A limiting groove 31 is provided on the shaft fixing block 63 for the locking rod 7 to pass through the shaft fixing block 63 and limit the rotation range of the cylinder head circumferential rotating shaft 3. The limiting groove 31 has two ends, which are a fully covered end and a fully open end respectively. The locking socket 8 matches the position of the fully covered end of the limiting groove 31. The limiting groove 31 is used to limit the rotation range of the cylinder head circumferential rotating shaft 3, that is, the two ends of the limiting groove 31 are used to make the cylinder head circumferential rotating shaft 3 have a limited forward rotation range and reverse rotation range. The cylinder head 2 opens during forward rotation and closes during reverse rotation. This can save the time used for opening or closing the cylinder head 2 and can also meet the stroke length of the driving shaft of the second cylinder 51, thereby avoiding the situation where the second cylinder 41 drives the cylinder head circumferential rotating shaft 3 to rotate when it is misoperated.

[0024] A sensed sheet 9 is provided on the circumferential rotating shaft 3 of the cylinder head, and a sensor 10 used in conjunction with the sensed sheet 8 is provided on the second cylinder bracket 5. The sensor 10 cooperates with the sensed sheet 9, that is, after the sensed sheet 9 is sensed by the sensor 10, the second cylinder 51 stops driving, which also means that the circumferential rotating shaft 3 of the cylinder head is rotated into place when the cover is closed. At the same time, the third cylinder 52 is also started synchronously, so that the locking rod 7 moves up through the limiting groove 31 and is placed in the locking hole 8 at the same time, so as to prevent the circumferential rotating shaft 3 of the cylinder head from rotating. This continuous automatic execution can reduce the number of operating steps.

[0025] The lower end of the cylinder head circumferential rotating shaft 3 is provided with a third cylinder bracket 20 located below the second cylinder bracket 5 and used to install the fourth cylinder 201. The fourth cylinder 201 is used to make the positioning edge of the cylinder head 2 separate from the retaining edge of the material cylinder 1, so as to avoid scratching between the positioning edge and the retaining edge when the cylinder head 2 is translated under the drive of the second cylinder 51.

[0026] 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.
