Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 7, the drum screen for screening plastic particles of the present invention comprises a fixing frame 10, a rolling frame 11 and a motor 12, wherein the motor 12 is installed on the fixing frame 10, a rotating shaft 13 is provided on the motor 12, the other end of the rotating shaft 13 is installed on the fixing frame 10 through a bearing seat, a supporting member 14 is provided at two ends of the rolling frame 11, and the rolling frame 11 is installed on the rolling frame 11 through the supporting member 14. The rotating shaft 13 is rotated by the motor 12, so that the rolling frame 11 on the rotating shaft 13 rotates. The lower end of the fixing frame 11 is also provided with a corresponding blanking box 111 for blanking plastic particles with different sizes through screening.

The rolling stand 11 includes a fixing ring 15, a reinforcing ring 16, and a fixing plate 17. The fixing ring 15 is mounted inside the reinforcing ring 16, the axes of the fixing ring 15 and the reinforcing ring 16 coinciding. The width of the reinforcement ring 16 is half the width of the fixing ring 15, which facilitates the ability of the extra fixing ring 15 to receive the screening deck 18. And the reinforcement ring 16 can block the screen deck 18 to prevent the screen deck 18 from shifting. Fixing rings 15 are installed at both ends of the fixing plate 14, and the fixing rings 15 are fixed to the fixing plate 17 by welding. The fixed plate 17 and the fixed ring 15 surround the sieve plate 18, and the sieve plate 18 can be replaced by a sieve screen according to the actual situation. The two ends of the screen plate 18 are overlapped, the two ends of the screen plate 18 are connected through a bolt 19, the bolt 19 penetrates out of the inner face of the fixing ring 15, a nut 20 is arranged on the bolt 19, and the nut 20 is arranged at the upper end of the screen plate 18. I.e. the screening deck 18 is secured to said securing ring 15 by means of bolts 19, thereby facilitating screening and facilitating mounting and replacement of the screening deck 18.

In order to facilitate the grinding of the sharp faces at the two ends of the screen plate 18, there may be insufficient time and no grinding place for the previous cutting, since the rolling frame 11 may be vibrated after the sharp faces are mounted on the rolling frame 11, which may cause the sharp faces of the screen plate 18 to damage the fixing ring 15. Be equipped with moving member 21 on mount 11, have on moving member 21 and insert board 22, insert board 22 and be used for supplementary sieve 18's the insertion, and can also polish sieve 18 or the both sides of screen cloth for the sharp face is smooth, can not damage solid fixed ring 15. The upper end of the insertion plate 22 has a triangular insertion opening 23, and the triangular insertion opening 23 is for facilitating insertion of the screen plate 18 or the mesh. The insertion plate 22 has an arc shape, and the lower end of the insertion plate 22 extends downward to be tangent to the fixing ring 15, so that the screen plate 18 inserted into the insertion plate 22 can smoothly move along the rolling frame 11. The insert plate 22 has grindstones 24 on both sides of the inside thereof, and the grindstones 24 are mounted on the insert plate 22 by fixing bolts 221. The moving member 21 is provided with an adjusting bolt 25, and the moving member 21 is fixed on the fixed frame 11 through the adjusting bolt 25.

The screen plate 18 is installed in a specific way, the moving member 21 is firstly installed on one end of a fixed frame 11 which needs to install the screen plate 18, then the screen plate 18 is inserted into the inserting plate 22, and the sharpening surfaces on two sides of the screen plate 18 are ground by the sharpening stone 24. Then, one inserted end of the sieve plate 18 is fixed on the bolt 19 and then fixed by the nut 20, then the fixing frame 11 is rotated to enable the sieve plate 18 to continuously enter the inserting plate 22, after one circle of rotation is finished, the other end of the sieve plate 18 enters the fixing frame 11, then the nut 20 on one side is taken down, one side of the sieve plate 18 is fixed on the bolt 19, the nut 20 is fixed, then the nut 20 on the other side is taken down, the sieve plate 18 on the other side is fixed on the bolt 19, and then the bolt 20 is used for fixing. The job of installing the screen deck 18 can be completed. The manner of mounting of the screen deck 18 at the other end is also not illustrated. When the sieve plate 18 is replaced, the sieve plate 18 can be removed only by taking down the screw cap 20 and then rotating the rolling frame 11.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
