Brief description of the drawings
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is electrical block diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1; a kind of plastic products corner machine of eliminating; comprise motor 1, transmission mechanism 2, support 3, cylinder 4, power line 5 and thermel protection device 6; motor 1 and cylinder 4 are arranged on support 3; cylinder 4 is laterally to place; the output shaft of motor 1 is connected with cylinder 4 by transmission mechanism 2, and cylinder 4 has a feeding mouth 40, and the side of cylinder 4 has a plane 41.The utility model in use, feeding mouth 40 is for putting into plastic products, and plane 41 makes cylinder 4 in the time that motor 1 drives rotation, can make plastic products in cylinder 4, rotate and polish corner, corner can be removed fast, and feeding mouth 40 should be used cap covers in the used time.Lid is departing or be arranged on feeding mouth 40 limits by hinge, uses bolt etc. to fix in the time covering, and avoids lid to open.Transmission mechanism 2 can use belt transmission (as shown in Figure 1) or gear drive.In cylinder 4, have dividing plate 43, dividing plate 43 can come the spatial separation of cylinder 4, avoids the mixing of multiple plastic products.Thermel protection device 5 is arranged on support 3, thermel protection device 6 comprises transformer, relay T1 and thermistor RD1, as shown in Figure 2, transformer is for converting civil power to direct current, two inputs of transformer are connected with the two ends of power line, an output of relay T1 is connected with one end of power line, another output of relay T1 is connected with an input of motor, another input of motor is connected with the other end of power line, an input of relay T1 and the output negative terminal of transformer, one end of the second resistance R 2 is connected with one end of thermistor RD1, another input of relay T1 is connected with the output of voltage comparator U2, the inverting input of voltage comparator U2 is connected with the other end of the second resistance R 2 and one end of the 3rd resistance R 3, the 3rd other end of resistance R 3 and the output plus terminal of transformer are connected with one end of the first resistance R 1, the in-phase input end of voltage comparator U2 is connected with the other end of the first resistance R 1 and the other end of thermistor RD1, the resistance of described thermistor RD1 is along with temperature becomes large and reduces, thermistor RD1 is arranged on motor 1 outer wall.The utility model in use, when temperature is normal, thermistor RD1 resistance is high, voltage on thermistor RD1 is also high, voltage comparator U2 in-phase input end voltage is greater than anti-phase input terminal voltage, voltage comparator U2 exports positive voltage, and relay T1 input obtains electric and attracting electric relay T1, uses the voltage of power line receive on motor and make electric machine rotation.In the time that temperature is elevated to certain numerical value, thermistor RD1 resistance reduces, lower voltage on thermistor RD1, voltage comparator U2 in-phase input end voltage is less than anti-phase input terminal voltage, not output voltage of voltage comparator U2, then make relay T1 input lose voltage and disconnect, motor does not rotate, and has avoided the damage of motor.For the temperature of needs control, only need select the resistance of the first suitable resistance R 1 to regulate, very convenient, this circuit is simple simultaneously, implement very quick, can speed production progress of the present utility model.
Wherein, transformer can be used 5V transformer, common voltage comparator U2 can use model lm393, the supply voltage of voltage comparator can directly be selected output or the external power supply of transformer, and thermistor RD1 selects the resistance 10K order of magnitude, the first resistance R 1 100K order of magnitude, the second resistance R 2 10K order of magnitude, the resistance R 3 100K order of magnitude, relay T1 selects input 5V, exports the relay of withstand voltage 220V.Above as just selecting fast reference.
The plane quantity that increases side can increase the impact machine meeting of plastic products, and cylinder 4 cross sections are octagon, and the side of cylinder 4 has 8 planes, and efficiency is higher.The side panel of cylinder 4 is preferably the softer panel of material, as plastic front board and plank, avoids scraping plastic products.For plastic products leftover pieces can be discharged, cylinder 4 sides have opening 42, and opening 42 places are provided with filter screen.
