Abstract
The utility model relates to a cutting mechanism for a material cutting machine, which belongs to the technical field of machinery. The utility model is designed to avoid or to reduce personal safety accidents. The utility model comprises a dead knife 1 fixedly arranged on a frame. The utility model is characterized in that the utility model is provided with a fixed sliding rail 3 parallel to the dead knife; a sliding block 4 is installed on the fixed sliding rail 3; the sliding block 4 is connected to a power source through a transmitting mechanism to cause that the sliding block slides back and forth on the sliding rail; a cutter shaft 21 is arranged on the sliding block 4; a cutter 2 in a round disk shape is arranged on the cutter shaft 21; the cutting edge of the cutter 2 and the cutting edge of the dead knife which are mutually matched form a pair of shearing edges. The transmitting mechanism is a belt (especially a synchronous belt) transmitting mechanism. The power source is an invertible motor 6 which is fixedly arranged on the frame. A feed motor matched with the power source adopts a step motor. The material cutting precision is improved through digital control technique. The invertible motor 6 is an automatic brake motor. When the invertible motor 6 losses electricity, a shaft is automatically locked by the invertible motor 6.
Description
Affiliated technical field
The utility model belongs to field of mechanical technique, relates in particular to the cutting mechanism of material cutting machine.
Background technology
The mechanical part of audio-video electronic product such as radio cassette player, DVD player and some instrument all has comparatively meticulous rubber part, and material cutting machine is one of equipment of producing these rubber parts, but material cutting machine is not limited to this range of application.Existing this kind material cutting machine, its cutting mechanism comprise a bed plate that installs, the upper slitter of a hinge on eccentric wheel; Upper slitter is along with upper and lower reciprocating motion is done in the rotation of eccentric wheel, cooperates with bed plate and finishes cutting rubber raw materials.The accident that the operative employee is pointed by this mechanical cutting usually takes place in the factory; and often occur under the situation of workman's extreme care---look like and shut down; hand is put in some operation of do; eccentric wheel has but turned over top dead-centre slowly according to inertia, drives upper slitter then and falls fast ...
Summary of the invention
Mainly be in order to overcome above-mentioned potential safety hazard, the utility model provides a kind of cutting mechanism of rubber material cutting machine, with protection workman's safety.
This purpose is achieved in that
A kind of cutting mechanism of rubber material cutting machine comprises a bed plate that is installed in frame, it is characterized in that: a fixed rack that is parallel to bed plate is arranged, slide block is installed on the slide rail, slide block is connected to power source (slide block is reciprocatingly slided) through transmission mechanism on slide rail; Cutter shaft is installed on the slide block; Discoid hobboing cutter is installed on the cutter shaft, and its cutting edge and bed plate cutting edge cooperatively interact and constitute a pair of shear blade.
The beneficial effects of the utility model: at first, because the source of shearing force does not rely on the accumulation of inertia and gravitional force, the alternation procedure of release, so the utility model can not jerked again and injury is personal thus afterwards in " shutdowns "; Moreover, in shear history, hobboing cutter is match with bed plate (its reason is analogous to its wheel of automobile that slides according to inertia and can rolls on the road surface) of rolling, the cut mode of Xing Chenging is more laborsaving thus, the existing model machine of the utility model, the power of the slide block drive motors of being joined (being following reversible electric machine 6) is 200w, can be competent at thickness is the cutting of the rubber raw materials of 15mm, and the power of the eccentric wheel drive motors of prior art is 3-4kw, and energy-saving effect is arranged; And the operating rate of existing model machine has surpassed 50 times/second, is much higher than the operating rate that has material cutting machine 30-40 time/second now.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. bed plate, 2. hobboing cutter, 21. cutter shafts, 3. slide rail, 4. slide block, 5. belt, 51. belt pulleys, 6. reversible electric machine, 7. contact switch.
The specific embodiment
As shown in the figure, a kind of cutting mechanism of rubber material cutting machine comprises a bed plate 1 that is installed in frame, it is characterized in that: a fixed rack 3 that is parallel to bed plate is arranged, slide block 4 is installed on the slide rail 3, and slide block 4 is connected to power source (slide block is reciprocatingly slided) through transmission mechanism on slide rail; Cutter shaft 21 is installed on the slide block 4; Discoid hobboing cutter 2 is installed on the cutter shaft 21, and its cutting edge and bed plate cutting edge cooperatively interact and constitute a pair of shear blade.
As shown in the figure, described transmission mechanism is belt (especially synchronous belt) transmission mechanism, and described power source is the reversible electric machine 6 that is installed in frame.That is: installing on slide rail 3 can contact switch 7 (according to the fabric width of rubber raw materials) adjusting position, that also can have time-delay to be provided with, is just changeing, reverses or be in the time-delay halted state by contact switch 7 control reversible electric machines 6; Two belt pulleys 51 are installed in the two ends of slide rail 3 respectively, and one of them is packed in the rotating shaft (or the rotating shaft through slowing down) of reversible electric machine 6; Belt 5 is installed on these two belt pulleys 51; A bit being connected mutually on slide block 4 and the belt 5.
On existing model machine, it is " the self-actuating brake motor " of automatic locking rotating shaft that reversible electric machine 6 has adopted dead electricity, more strengthens its security.
In addition, supporting feeding motor adopt stepper motor, by Numeric Control Technology, can improve and cut out the material precision.
By said structure as seen, under the situation of closing machine power supply (power supply that comprises feeding motor and reversible electric machine 6), the utility model can not jerked and be caused the personal safety accident.
