In order to facilitate understanding for those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and examples.
To overcome the above technical problems, the present invention provides a compressing and cutting device 100 for a nose bridge of a mask
As shown in fig. 1-2, the present invention provides a compressing and cutting device 100 for a nose bridge strip of a mask, comprising a first blade 1, a second blade 2, a first transmission rod 3, a second transmission rod 4, a first buffer part 5, a second buffer part 6, a power assembly, a synchronous control module, a cross-connecting slot 7, and a compressing wheel;
the first blade 1 is connected with the first transmission rod 3; the second blade 2 is connected with a second transmission rod 4; the first buffer part 5 is movably connected with the first blade 1; the second buffer part 6 is movably connected with the second blade 2;
the power assembly is connected with the first transmission rod 3 and the second transmission rod 4;
the synchronous control module is electrically connected with the power assembly and is used for controlling the first transmission rod 3 and the second transmission rod 4 to move in the same direction;
the penetrating groove 7 is located on one side of the first blade 1 and one side of the second blade 2, is movably connected with the pressing wheel, and is used for penetrating a nose bridge strip to enable the nose bridge strip to move on the penetrating groove 7.
Specifically, a small distance is reserved between the axial distances between the first blade 1 and the second blade 2, so that the first blade 1 and the second blade 2 are prevented from touching when cutting a nose bridge strip; the cross-sections of the first blade 1 and the second blade 2 are both triangular.
When the nose bridge strip is connected out of the through groove 7 in a penetrating mode through the driving of the pressing wheel, the synchronous control module controls the power assembly to output power to the first transmission rod 3 and the second transmission rod 4 simultaneously, so that the first transmission rod 3 and the second transmission rod 4 can move in the same direction at the same speed, and the first blade 1 and the second blade 2 connected with the first transmission rod 3 and the second transmission rod 4 are driven to move in the same direction. When the first blade 1 and the second blade 2 simultaneously cut the nose bridge strip, a shearing force is formed to cut the nose bridge strip.
The prior art only has a blade usually, and the other end passes through other blunt nature components and constitutes, and this results in the blade to be asymmetric with the shearing stress that blunt nature component formed to make nose bridge strip cut off the tangent plane atress that forms inhomogeneous at the cutting-off in-process, if some nose bridge strips that toughness is stronger not enough are difficult to cut off, need increase the impact force at this moment and can make nose bridge strip cut off more easily, and this noise that leads to the device increases.
In the design of the nose bridge strip cutting device, the blades on the two sides are simultaneously carried out in the cutting process of the nose bridge strip, so that the cutting forces on the two sides are symmetrical and the same, and the formed cutting force can rapidly cut the nose bridge strip.
In some solutions, the first transmission lever 3 comprises a first pulley 31; the second transmission rod 4 comprises a second pulley 41.
The design of the pulley can reduce the resistance of the transmission rod in the movement process, so that the power provided by the power assembly can be reduced, and the reduction of the power means that the buffering power born by the buffering part can be reduced, thereby reducing the vibration amplitude of the whole device and reducing the noise of the whole device.
In some aspects, the synchronization control module includes a touch screen.
When the nose bridge strip is replaced by the cross-connecting groove 7, the impact force required for cutting the nose bridge strip can be changed, and the power parameters required by the power assembly can be directly input or adjusted through the touch screen, so that the power parameters required by adapting to different types of nose bridge strips are achieved. Compared with other key input methods, the touch screen input method is faster.
In some embodiments, the drive link is movably coupled to the blade.
Specifically, the drive link includes a drive link threaded aperture and the blade includes a blade threaded aperture; correspondingly, the screw and the nut are further included in the embodiment, the screw can penetrate through the two holes, namely the threaded hole of the driving rod and the threaded hole of the blade, and the tail end of the screw is screwed by the nut.
When the blade needs to be replaced, the machine can be stopped, and the nut screw can be unscrewed to replace the blade.
In some embodiments, the synchronization control module includes a displacement sensor disposed on a centerline of the two blades.
The displacement sensor detects the instant contact of the two blades, and immediately sends a contact signal to the synchronous control module, and the synchronous control module immediately controls the first transmission rod 3 and the second transmission rod 4 to stop advancing, so that the impact of the first transmission rod 3 and the second transmission rod 4 on the buffer part can be reduced, and the noise is reduced. When necessary, the synchronous control module can provide a signal of reverse movement to the power assembly when controlling the power assembly to stop transmitting power to the transmission rod, so that the time of stay of the nose bridge strip in the advancing process due to cutting is shortened.
In some aspects, the displacement sensor includes a laser transmitter and a laser receiver.
Specifically, the laser transmitter and the laser receiver are arranged on the central line of the first blade 1 and the second blade 2 when in contact with each other, and are parallel to the central line of the through groove 7.
The bridge of the nose strip production line during operation, laser emitter opens always, and laser receiver can receive the laser that laser emitter launched, moves in opposite directions as first blade 1, second blade 2, when taking place the contact with the bridge of the nose strip, can block the transmission of laser, and laser receiver does not receive laser, just does not have this signal transmission that laser received to synchronous control module to control power component's power take off. The existing laser transmitter and laser receiver have good sensitivity when sensing the movement of the blade, and can sense whether the blade moves to the appointed position where the nose bridge strip can be cut or not in real time.
The foregoing is only a few embodiments of the present invention, and it should be noted that other variations and modifications could be made by those skilled in the art without departing from the inventive concept of the present invention, which falls within the scope of the appended claims.
