Further, since the average temperature of the whole environment of the ceramic tile production line is high, and the frequency converter itself generates heat, in order to avoid the performance of the permanent magnet synchronous motor 100 from being reduced due to the influence of high temperature on the magnetism of the permanent magnet synchronous motor 100, in an embodiment of the present invention, the ceramic intelligent all-in-one machine 10 further includes a heat dissipation fan 400, the heat dissipation fan 400 is disposed in the housing 200, one side of the housing 200 is open, the open side of the housing 200 is connected with the rear end cover 120, and the other end of the output shaft 140 extends out of the rear end cover 120 to enter the housing 200 to be connected with the heat dissipation fan 400.

It can be understood that, with this arrangement, the heat dissipation fan 400 is disposed between the permanent magnet synchronous motor 100 and the driver 300, and only one heat dissipation fan 400 can be used to dissipate heat of the permanent magnet synchronous motor 100 and the driver 300 at the same time, so as to prevent heat generated by the driver 300 from being conducted to the permanent magnet synchronous motor 100 through the casing 200 and the rear end cover 120, thereby avoiding performance degradation of the permanent magnet synchronous motor 100.

Further, in an embodiment, in order to further reduce the temperature inside the permanent magnet synchronous motor 100, a plurality of air inlets 210 are disposed on the side surface of the housing 200 corresponding to the heat dissipation fan 400, a plurality of air outlets 170 are disposed on the side of the rear end cover 120 facing the permanent magnet synchronous motor 100, and the heat dissipation fan 400 rotates to draw air into the housing 200 from the air inlets 210 and blow the air into the permanent magnet synchronous motor 100 from the air outlets 170. Inside air outlet 170 intercommunication casing 200 and permanent magnet synchronous motor 100, when permanent magnet synchronous motor 100 rotated and drive radiator fan 400 and rotate, form the negative pressure with the outside air of casing 200 from air intake 210 suction casing 200 to inside blowing in permanent magnet synchronous motor 100 from air outlet 170 under radiator fan 400's drive, and then take away the heat in permanent magnet synchronous motor 100, make permanent magnet synchronous motor 100 cool down, avoid influencing permanent magnet synchronous motor 100's working property.

Further, in order to prevent large particle dust in the tile production line from entering the housing 200 and the interior of the permanent magnet synchronous motor 100, in an embodiment, a baffle is further connected to a side surface of the housing 200 corresponding to each air inlet 210, the baffle is disposed above the air inlet 210, and the baffle and the side surface of the housing 200 are disposed at a preset angle. In this embodiment, the baffle and the housing 200 are integrally formed, specifically, the baffle is formed by cutting a contour by laser, and then the baffle is bent by a predetermined angle toward the outside of the housing 200 by a bending tool, so as to form the air inlet 210. In this way, in the process that the heat dissipation fan 400 rotates to form wind pressure to draw air into the housing 200 from the wind inlet 210, large particles are blocked on the baffle. It is noted that the preset angle here is 10 ° to 30 °.

Further, in an embodiment, in order to further prevent dust in the environment of the tile production line from entering the interior of the permanent magnet synchronous motor 100, the air inlet 210 and the air outlet 170 are further provided with filtering members 500. So, under baffle and the common cooperation of filtering piece 500, can also prevent that the tiny particle dust in the environment from getting into inside casing 200 and PMSM 100, prevent that the dust from piling up and making PMSM 100 generate heat seriously, avoid causing the corruption to PMSM 100 inside simultaneously. The filter 500 may be a filter net or a filter sheet. It will be appreciated that the filter 500 may be implemented in multiple stages for maximum dust filtration, and of course, the number of stages of the filter 500 is properly designed considering that air can be smoothly drawn into the housing 200 from the inlet 210.

Further, in order to increase the amount of air entering the housing 200 and the interior of the permanent magnet synchronous motor 100 under the condition that the air inlet 210 and the air outlet 170 are fixed, in an embodiment of the present invention, the heat dissipation fan 400 is a mixed flow fan. Compared with the traditional axial flow fan, the mixed flow fan has higher flow and wind pressure, so that the flow of air is accelerated, and the heat exchange effect is enhanced.

Further, in one embodiment, in order to achieve the above purpose, the ceramic smart all-in-one machine 10 further includes a photoelectric eye sensor, and the photoelectric eye sensor is electrically connected to the driver 300. Wherein, photoelectricity eye sensor installs in casing 200 and deviates from its one side that has the opening, and photoelectricity eye sensor is connected with the control module of driver 300, and photoelectricity eye sensor is used for detecting whether there is the ceramic tile on the conveyer belt to feed back detection signal to control module, so that control module controls the start and the stop of PMSM 100 according to the detection signal that corresponds. When the photoelectric eye sensor detects that the conveyor belt has tiles, it sends a signal to the control module to cause the control module to control the start of the permanent magnet synchronous motor 100. Understandably, the photoelectric eye sensor is integrated in the ceramic intelligent all-in-one machine 10, so that a control circuit can be simplified, later maintenance is facilitated, and the phenomenon that the corresponding photoelectric eye sensor cannot be quickly positioned due to complex circuits is avoided.

Further, in an embodiment, the integrated ceramic smart machine 10 further includes a connection terminal, and the connection terminal is electrically connected to the driver 300. Wherein, casing 200 deviates from its one side that has the opening and has seted up the third mounting hole, and binding post passes third mounting hole and the driver 300 electric connection in the casing 200, and binding post is used for being connected with external power source to the power supply to driver 300 and PMSM 100.
