Abstract

The utility model discloses a throwing machine, comprising a housing, a mud shielding disc, a working disc, a motor, a rotating wheel, a connecting plate, a spindle, a countershaft and belt pulleys interlinked with the spindle and the countershaft, which is characterized in that a triangular gearshifting cone pulley is arranged on a rotating shaft of the motor to drive the rotating wheel to rotate; the rotating speed of the rotating wheel is controlled by the triangular cone pulley so as to realize the stepless speed regulation of the working disc rotation. The utility model has the advantages of simple structure, high safety, easy maintenance and low cost.

Description

Blank drawing machine

Technical field:

The utility model relates to a kind of Blank drawing machine, particularly a kind of Blank drawing machine of making ceramics and ceramic articles for use.

Background technology:

Blank drawing machine has another name called winch, put mud into Blank drawing machine after, the scratch diskette of Blank drawing machine rotates, and can produce the ceramic plain embryo of different shape.Present Blank drawing machine adopts variable speed electric motors, particularly usually, because common variable speed electric motors, particularly can not satisfy its production required precision, and infinite variable speed motor has complex structure, security performance is relatively poor, easy-maintaining not, and shortcoming such as involve great expense, therefore, brought inconvenience to production.

Summary of the invention:

Goal of the invention of the present utility model is, designs a kind of Blank drawing machine, by mechanical device, the scratch diskette of Blank drawing machine is carried out stepless speed regulation, to improve the security of Blank drawing machine, reduces its production cost.

For achieving the above object, the technical solution of the utility model is: a kind of Blank drawing machine, comprise box body, retaining mud pan, scratch diskette, motor, runner, connecting plate, main shaft, countershaft, and the belt pulley of interlock main shaft and countershaft, it is characterized in that: in the rotating shaft of described motor, be equipped with and drive the speed change triangle cone pulley that runner rotates.

In the rotating shaft of Blank drawing machine described in the utility model, be equipped with and drive the speed change triangle cone pulley that runner rotates, by the rotary speed of pyrometric cone wheel adjusting runner, thus the stepless speed regulation of the rotation of realization scratch diskette.Because this mechanic adjustment unit is simple in structure, therefore, this Blank drawing machine is safe, and is for ease of maintenaince, cheap.

Description of drawings:

Fig. 1 is the structural representation of Blank drawing machine described in the utility model;

Fig. 2 is the structural representation of the varying-speed machinery device of Blank drawing machine described in the utility model;

Fig. 3 is the schematic diagram of the runner vibration absorber of Blank drawing machine described in the utility model;

Fig. 4 is the rubber damper scheme of installation of Blank drawing machine described in the utility model.

The specific embodiment:

As shown in Figure 1, the Blank drawing machine that the utility model is designed, form by box body 15, retaining mud pan 1, in the retaining mud pan 1 scratch diskette 2 that stirs mud is installed, in the box body 15, motor 13, runner 22, main shaft 3, countershaft 7 are installed, and the belt pulley 6 of interlock main shaft 3 and countershaft 7, in the rotating shaft 4 of motor 13, speed change triangle cone pulley 11 is installed.

When motor 13 along it during axially near runner 22, triangle cone pulley 11 enlarges gradually with the circumference that runner 22 contacts, and runner 22 rises along countershaft 7, and the rotating speed of runner 22 increases, the countershaft 7 of runner 22 quickens rotation by the main shaft 3 that belt drives belt pulley 6, thereby accelerates the rotating speed of scratch diskette 2; Otherwise, when motor 13 along it during axially away from runner 22, triangle cone pulley 11 dwindles gradually with the circumference that runner 22 contacts, runner 22 descends along countershaft 7, interlock belt pulley 6, main shaft 3 slow down the speed of scratch diskette 2.

As shown in Figure 2, regulate the axially mechanical device of advance and retreat of motor 13, the handspike 19 and the pedal 20 that comprise rotating shaft 17 and rotating shaft 17, when promoting handspike 19 or depressing pedal 20, handspike 19 or pedal 20 rotate by gears engaged rotating shaft 17, it moves vertically to drive motor 13, the triangle cone pulley of installing in the rotating shaft 4 of motor 13 11 is advanced or retreats, to regulate scratch diskette 2 velocities of rotation.One end of rotating shaft 17 and handspike 19 and pedal 20 interlocks, the other end is equipped with degree of tightness nut 16, and the negative of box body 15 inside is provided with the screens of degree of tightness nut 16, makes rotating shaft 17 when work, is unlikely to produce excessive displacement.

For operating noise and the vibration that reduces Blank drawing machine, multiple vibration absorber that the utility model has also designed, as Fig. 1, Fig. 3, shown in Figure 4, on the connecting plate 21 of motor 13, and on the connecting plate 21 of rotating shaft 17 holding screw 5 is installed all, between corresponding two holding screws 5 in position, connect with rubber screw cushion blocking 8, this rubber screw cushion blocking 8 is one cylindrical, and two ends are the screw blind hole, holding screw 8 is tightened in the screw blind hole, played the favorable damping effect.

The top and the bottom of the countershaft 7 in the runner 22 by two connecting plates 21, are fixed on the box body 15 respectively, on connecting plate 21 and box body 15 sidewalls, holding screw 5 all is installed, between corresponding two holding screws 5 in position, connects with rubber screw cushion blocking 8.

The edge of runner 22 with the part of triangle cone pulley 11, is equipped with rubbery friction ring 10, vibration in the time of can reducing speed governing and noise.

The lower margin of the bottom of box body 15 is a rubber lower margin 14, can the buffer casing 15 with the vibration on ground.

Rubber screw cushion blocking 8 of the present utility model and rubbery friction ring 10, and damping means such as rubber lower margin 14 also can be made with other flexible material.
