Description
Technical field
The utility model relates to packaging facilities technical field, particularly relates to a kind of paper cutting mechanism of paper cutter.
Background technology
Paper cutting mechanism is parts paper cutter being used for cut paper.
In prior art, be disclose a kind of paper cutting mechanism in the Chinese utility model patent of 201220567412.X in the patent No..Determining plate to be provided with punch and stationary knife, determine to be connected firmly by trip bolt and stationary knife inside plate, determine the upper and lower both sides of plate and connecting axle is connected, connecting axle is provided with sliding guide sleeve, sliding guide sleeve is connected by screw and sliding panel, sliding panel and die are connected, and inside die, moving knife are housed, and moving knife is connected by screw and die; It is characterized in that: stationary knife upper/lower terminal boss cuts face length than cutter, increase oblique angle, stationary knife blade place, increase oblique angle, moving knife blade place.There is easy to adjust, that reliable in action, cut paper are effective advantage.
But, in the cutting work of reality, be easy to occur that paper does not also transmit and put in place, cutting knife just carries out the situation of cutting work, i.e. so-called " cutting sky cutter " phenomenon, in this case, because blade is and the direct collision of Paper Cutter's station, be easy to hit cutter and cause blade to damage.
Utility model content
Technical problem to be solved in the utility model provides a kind of paper cutting mechanism that can effectively prevent cutting knife from damaging for the above-mentioned state of the art.
For achieving the above object, the utility model provides following technical scheme:
A kind of paper cutting mechanism of paper cutter, include cutting knife and tool rest, described tool rest is fixedly mounted in the frame of paper cutter, described cutting knife is removably connected to the bottom of described tool rest, it is characterized in that: also include overvoltage protection mechanism, described overvoltage protection mechanism is clamped between described tool rest and described cutting knife, cavity is formed in described overvoltage protection mechanism, the size of described cavity and the size of described cutting knife suitable, and described cutting knife part is placed in described cavity, elastic mechanism is provided with in described cavity, described elastic mechanism can apply reciprocal restoring force to it all the time when described cutting knife moves upward.
As improvement of the present utility model, described elastic mechanism is the spring with specified maximum elastic force.
Improve as another kind of the present utility model, described elastic mechanism is the elastic washer with specified maximum elastic force.
As further improvement of the utility model, described removably connection refers to that the two ends of described cutting knife are respectively arranged with connecting bolt, the both sides inwall of described tool rest offers chute respectively, and described bolt to be slidably connected in described chute and to be limited in above-mentioned chute.
Compared with prior art; the utility model has the advantage of: by arranging an overvoltage protection mechanism between cutting knife and tool rest; when cutting sky cutter; opposition suffered by cutting knife exceedes the specified maximum elastic force of elastic mechanism; cutting knife will be broken through in the cavity of restriction retraction overvoltage protection mechanism of elastic mechanism, thus plays the protection to cutter.
Accompanying drawing explanation
Fig. 1 is the structural representation of paper cutter and paper cutting mechanism in the utility model embodiment;
Fig. 2 is the partial structurtes schematic diagram of middle overvoltage protection mechanism embodiment illustrated in fig. 1.
Reference numeral:
1, cutting knife; 2, tool rest; 21, chute; 3, frame; 4, overvoltage protection mechanism; 41, cavity; 5, elastic mechanism.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, the present embodiment is a kind of paper cutting mechanism of paper cutter, include cutting knife 1 and tool rest 2, described tool rest is fixedly mounted in the frame 3 of paper cutter, the modes such as described cutting knife is then threaded connection removably are connected to the bottom of described tool rest, refer to that the two ends of described cutting knife are respectively arranged with connecting bolt particularly, the both sides inwall of described tool rest offers chute 21 respectively, described bolt to be slidably connected in described chute and to be limited in above-mentioned chute.This mode removably connected is convenient on the one hand to be changed cutting knife, is also conducive to often cleaning tool rest on the other hand, prevents the joint portion of tool rest and cutting knife from affecting cut paper effect due to accumulation of mud.
Above-mentioned paper cutting mechanism also includes overvoltage protection mechanism 4, described overvoltage protection mechanism is clamped between described tool rest and described cutting knife, particularly, as shown in Figure 2, the threaded upper ends of this overvoltage protection mechanism is connected on tool rest, cavity 41 is formed in its lower end, the size of described cavity and the size on described cutting knife top suitable, cutting knife top can be held stretch into, and in an initial condition, the top of described cutting knife is placed in described cavity, elastic mechanism 5 is provided with in described cavity, this elastic mechanism can for having spring or the elastic washer of specified maximum elastic force, here specified maximum elastic force can adjust according to the model of cutting knife.Described elastic mechanism can apply reciprocal restoring force to it all the time when described cutting knife moves upward.
When carrying out cut paper operation; once cut the phenomenon of sky cutter; the instantaneous reaction force that cutting knife is subject to increases rapidly; when this reaction force increases above the specified maximum elastic force of elastic mechanism; elastic mechanism cannot reoffer enough restoring forces and stop cutting knife upwards; now the restriction breaking through elastic mechanism enters in the cavity of overvoltage protection mechanism by cutting knife, thus plays the protective effect to cutting knife.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
