Abstract
The utility model relates to powder dry grinding machinery, particularly to an automatic cooling fluoroplastic pulverizer. The automatic cooling fluoroplastic pulverizer comprises a grinding wheel (5), wherein a grinding wheel (5) is fixedly mounted in the middle of a grinding wheel main shaft (2); the two ends of the grinding wheel main shaft (2) are rotationally arranged on bearing supports (4) through bearings (3); a cooling through hole (6) is formed in the grinding wheel main shaft (2) along the axle center; and one end of the cooling through hole (6) is connected with a water pump (1). The cooling through hole is formed in the grinding wheel main shaft, and running cold water is led to the cooling through hole, so as to play a fast cooling effect to the grinding wheel main shaft; the cooling through hole takes a special shape which is smaller at two ends and large in the middle, so that speed of heat transmission of the grinding wheel main shaft to the bearing can be slowed down, and the cooling effect is further improved.
Description
Technical field
The utility model relates to a kind of powder dry grinding machinery, and the fluorine that relates in particular to a kind of automatic cooling is moulded flour mill.
Background technology
Along with development of technology, the operating efficiency that fluorine is moulded flour mill greatly improves, some stubborn problems have also been produced simultaneously, the emery wheel of rotation at a high speed for example, rotating speed can reach 2000 rev/mins, in dry grinding abrasive dust process, can produce a lot of heats, the ball bearing heating at grinding wheel spindle two ends is scalded one's hand, lubricating oil in the ball bearing, also can slowly evaporate,, cause bearing dry friction rotation at last and kill until withered because of bearing heating, therefore bearing and grinding wheel spindle often damage, the replacing bearing and even the grinding wheel spindle of having to frequent, the cost of repairs continues to increase, and has improved production cost.
The utility model content
The utility model provides a kind of fluorine of automatic cooling to mould flour mill, can reduce self high temperature rapidly, and long service life has reduced production cost.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:
A kind of fluorine of automatic cooling is moulded flour mill, comprises emery wheel, and described emery wheel is fixedly mounted on the middle part of grinding wheel spindle; The two ends of described grinding wheel spindle are rotated by bearing and are arranged on the bearing block; Described grinding wheel spindle is got through a cooling through hole along the axle center; One end of described cooling through hole connects water pump.
Described cooling through hole is the little shape broad in the middle in two at the grinding wheel spindle middle part, and emery wheel is positioned at the aperture maximum.
The beneficial effects of the utility model are: establish the cooling through hole in the grinding wheel spindle, feed circulation cold water in the cooling through hole, played the grinding wheel spindle effect of cooling rapidly; The little special shape broad in the middle in cooling through hole two has slowed down the speed that the main shaft heat transmits to the bearing direction, has further improved cooling effect.
Description of drawings
Fig. 1 moulds the structural representation of flour mill for the fluorine of a kind of automatic cooling of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the fluorine of a kind of automatic cooling of the utility model is moulded the preferred implementation of flour mill and is made detailed description:
As shown in Figure 1, the groundwork that this fluorine that cools off is automatically moulded flour mill partly is emery wheel 5, emery wheel 5 is fixedly mounted on the middle part of grinding wheel spindle 2, the two ends of grinding wheel spindle 2 are rotatably assorted by ball bearing 3 and bearing block 4, grinding wheel spindle 2 is rotated by motor-driven, and then drive emery wheel 5 rotation at a high speed, finish fluorine and mould the dry grinding abrasive dust.
Grinding wheel spindle 2 is got through a cooling through hole 6 along its axle center, the cross section, hole of cooling through hole 6 is circular, and its circle is positioned on the axial line of grinding wheel spindle 2, and the position of emery wheel 5 is installed at grinding wheel spindle 2 middle parts, cooling through hole 6 is the little spindle shape broad in the middle in two, and emery wheel 5 is positioned at the position of aperture maximum.The left end of cooling through hole 6 is connected water pump 1, and the outlet pipe of water pump 1 is embedded in cooling through hole 6 left ends and supplies water in the hole, and the right-hand member of cooling through hole 6 is connected drainpipe, and drainpipe is enclosed within outward on the grinding wheel spindle 2.
When this fluorine that cools off was automatically moulded flour mill work, emery wheel 5 produced high temperature owing to rotate dry friction at a high speed, and heat is passed to grinding wheel spindle 2 by emery wheel 5, again to bearings at both ends 3 direction transmission; Water pump 1 is evacuated to cold water in the cooling through hole 6, and cold water absorbs the heat of taking away on the grinding wheel spindle 2 when flowing in cooling through hole 6; The cooling through hole 6 that emery wheel 5 positions are installed is the little shape broad in the middle in two, cold water time of staying in this section cooling through hole 6 increases, and cold water is along with grinding wheel spindle 2 rotation at a high speed, under action of centrifugal force, can rest on the long period on the hole wall of cooling through hole 6, improve the absorption efficiency of heat, this section cooling through hole 6 is owing to install aperture, the belly position maximum of emery wheel 5, the cold water of emery wheel 5 positions compiles at most, thereby the heat very first time that emery wheel 5 is delivered to grinding wheel spindle 2 sponges to greatest extent, has slowed down the speed that heat transmits to bearing 3.
Claims (2)
1. a fluorine that cools off is automatically moulded flour mill, comprises emery wheel (5), and described emery wheel (5) is fixedly mounted on the middle part of grinding wheel spindle (2); The two ends of described grinding wheel spindle (2) are rotated by bearing (3) and are arranged on the bearing block (4); It is characterized in that: described grinding wheel spindle (2) is got through a cooling through hole (6) along the axle center; One end of described cooling through hole (6) connects water pump (1).
2. the fluorine of a kind of automatic cooling according to claim 1 is moulded flour mill, it is characterized in that: described cooling through hole (6) is the little shape broad in the middle in two at grinding wheel spindle (2) middle part, and emery wheel (5) is positioned at the aperture maximum.
