Detailed Description
Example 1
See fig. 1, the rock wool fiber-forming centrifuge of the embodiment comprises a frame 1, a plurality of centrifugal roller assemblies 2 arranged on the frame 1, a split type glue spraying ring 3 arranged around the centrifugal roller assemblies 2, and a glue supplying mechanism for supplying glue to the centrifugal roller assemblies 2 and the split type glue spraying ring.
Referring to fig. 2 and 3, the centrifugal roller assembly 2 includes a motor 21, a coupling 22, a connection pipe 23, and a roller body 24. The output shaft 211 of the motor 21 is a hollow shaft penetrating through both ends of the motor 21, so that glue can be fed from the output shaft 211 of the motor 21. The output shaft 211 of the motor 21 is fixedly connected with the roller body 24 through the coupling 22.
The coupling 22 includes a first sleeve 221, a second sleeve 222, and a third sleeve 223 fixedly connected in sequence by bolts. The first sleeve 221 and the third sleeve 223 are respectively sleeved on the output shaft 211 of the motor 21 and the roller body 24. The side surface of the first shaft sleeve 221 is fixedly connected with the output shaft 211 of the motor 21 by a screw. A diaphragm 224 is disposed between the first sleeve 221 and the second sleeve 222, and a central hole through which the connection pipe 23 passes and a positioning hole through which the bolt passes are disposed on the diaphragm 224. A gap is formed between the inner wall of the third sleeve 223 and the outer wall of the roll body 24, and an expansion device 225 is disposed in the gap. The expansion device 225 may be selected from an expansion sleeve or key (expansion sleeve shown in fig. 2). The end surface of the second sleeve 222 connected with the third sleeve 223 is provided with a positioning step 226 matched with each other.
The connecting pipe 23 is located inside the coupling 22, and both ends of the connecting pipe 23 are connected to the output shaft 211 of the motor 21 and the roller body 24, respectively. One end of the connecting pipe 23 is inserted into the output shaft 211 of the motor 21, and the other end is inserted into the roller body 24. Steps are formed on the outer circumferential surfaces of both ends of the connection pipe 23, and the two steps respectively abut against the end surface of the output shaft 211 of the motor 21 and the end surface of the roller body 24, thereby preventing the connection pipe 23 from moving in the axial direction. Sealing rings 231 are arranged between the connecting pipe 23 and the output shaft 211 of the motor 21 and between the connecting pipe 23 and the roller body 24, so that the sealing performance between the connecting pipe and the output shaft 211 of the motor 21 and the roller body 24 can be improved, and glue leakage can be prevented.
The roller body 24 is internally provided with a rubber spraying pipe 25 communicated with the connecting pipe 23. The output shaft 211 of the motor 21, the connecting pipe 23 and the glue spraying pipe in the roller body 24 form a glue channel of the centrifugal roller assembly 2.
Referring to fig. 3, the roller body 24 includes a roller head 241, a rotation shaft 242, a rotation shaft housing 243, and at least one cooling tube 244 mounted on an outer surface of the rotation shaft housing 243.
The third sleeve 223 of the coupling 22 is fitted over the rotation shaft 242, and a limiting step 2421 that can limit the third sleeve 223 is provided on the outer circumferential surface of the rotation shaft 242.
The roller head 241 is internally provided with a cooling cavity 2411, and the front end surface of the roller head 241 is provided with a plurality of water outlets 2412 communicated with the cooling cavity 2411. The roller head 241 is fitted over and fixed to the front end portion of the rotation shaft 242. The hose 25 is disposed in the rotary shaft 242. The rotating shaft housing 243 is sleeved on the rotating shaft 242, and the rotating shaft housing 243 is connected with the rotating shaft 242 through a bearing so as to facilitate the rotation of the rotating shaft 242.
The cooling pipe 244 communicates with a cooling cavity 2411 in the roller head 241 to cool the roller head 241. The plurality of cooling pipes 244 can enhance the cooling effect.
An annular notch 2413 is provided on the rear face of the roller head 241 in communication with the cooling cavity 2411. The outlet of the cooling tube 244 is disposed in the annular slot 2413 to facilitate communication of the cooling tube with the cooling cavity in the roller head. The annular notch 2413 is communicated with the cooling cavity 2411 through a plurality of inclined through holes 2414, and one end of the inclined through holes 2414, which is communicated with the annular notch 2413, is closer to the center of the roller head 241 than the end, which is communicated with the cooling cavity 2411, so that when the roller head 241 rotates, cooling liquid conveniently enters the cooling cavity of the roller head through centrifugal force.
Each roller body of the rock wool fiber forming centrifuge needs to be filled with cooling liquid for cooling the roller head so as to avoid overheating of the roller head. However, in the prior art, the cooling pipes are basically arranged inside the roller body, and the rubber spraying pipes are arranged in the cooling pipes, so that the cooling effect of the roller head is restricted due to limited amount of cooling liquid, and finally the quality of the produced product can be influenced. In addition, because the cooling tube sets up inside the roll body, when the roll body high-speed rotation, the cooling tube also rotates at a high speed, and consequently the water inlet seal of cooling tube is very difficult, and seal structure is extremely fragile, and maintenance cost is high. According to the invention, the cooling pipe 244 is arranged outside the rotating shaft shell 243, so that the cooling pipe can be prevented from occupying the inner space of the rotating shaft 242, the inflow amount of cooling liquid can be increased, the cooling effect is improved, and the product quality is further improved; meanwhile, the cooling pipe 244 is arranged externally and does not rotate along with the rotating shaft 242, so that the structure of the water inlet of the cooling pipe is not easy to damage, special sealing design is not needed, and maintenance cost is effectively reduced.

The glue spraying head 31 is also provided with at least one glue through hole 315 and at least one vent hole 316, the glue through hole 315 is arranged at the rear part of the glue spraying head 31, and the vent hole 316 is arranged at the middle part of the glue spraying head 31. The glue hole 315, the glue channel 311 and the glue spraying port 313 are communicated in sequence. The vent holes 316, the gas passages 312, and the gas nozzles 314 are communicated in sequence; the glue through holes 315 of the plurality of glue spray heads 31 (only four are shown in the drawing, or more glue through holes can be arranged) are sequentially communicated through the glue through pipe 32, and the vent holes 316 of the plurality of glue spray heads 31 are sequentially communicated through the vent pipe 33. In order to facilitate the arrangement of the pipes, the hose is sampled by both the hose 32 and the vent pipe 33.
The glue spraying head 31 provided with a glue through hole 315 and a vent hole 316 can be used as the last glue spraying head 31 of the glue and gas flow path of the whole glue spraying mechanism. Of course, more than one glue hole 315 and one vent hole 316 may be used for the glue spraying heads 31, and only the redundant glue holes 315 and vent holes 316 of the last glue spraying head 31 are blocked by plugs.
The nozzle 317 is fixed to the front end surface of the glue nozzle 31 by welding, screwing, or the like. The nozzle 317 is provided with a glue hole 318 and a plurality of air injection holes 319 provided around the glue hole 318. The glue spraying hole 318 communicates with the glue spraying port 313.
