Alternatively, when the cutting mechanism 10 is the slitting mechanism 14,

in an alternative embodiment, the air shaft, also adapted to the control mechanism 30, may be used to secure the longitudinally cut roll.

For example: referring to the examples shown in fig. 2-7, the slitting section is constructed and functions as follows:

1) the diaphragm photoelectric deviation-rectifying sensor: the left and right positions of the diaphragm on the rolling shaft are detected in real time, position information is transmitted to a deviation rectification control system of a shared material rack, and the position of the material rack controlled by a first servo motor is automatically adjusted left and right to guarantee cutting precision of the diaphragm during cutting.

2) Frame, roller bearing and pressure sensor, second servo motor and inflatable shaft: the machine frame and the rolling shaft provide the function of conveying the film roll, the pressure sensor detects the tension condition in real time and feeds the tension condition back to the magnetic powder brake, the second servo motor provides a tension power source required by the film roll during cutting, and the tension and the speed are controlled through the comprehensive control of the magnetic powder brake. The air expansion shaft is used for fastening the material roll after splitting.

Wherein, a roller can be arranged on the frame to fix the knife rest.

3) Knife rest and blade: the fixed tool rest is used for mounting four tool rests with adjustable positions and fixing the blades on the tool rests with adjustable positions. The knife rest is provided with a knife seat with adjustable position for providing the requirements of the strip film roll in various width ranges. According to the width of the film rolling sheet, the cutting efficiency can be improved by simultaneously slitting and cutting four knives. A cutter advancing/retreating cylinder is arranged on the cutter holder with the adjustable position to control the feeding and retreating of the cutter.

For example: referring to the examples shown in fig. 2-7, the cross-section is constructed and functions as follows:

2) Mechanism is got to frame, roller bearing and pressure sensor, pay-off clamp: the frame and the rolling shaft provide the function of conveying the film roll; the pressure sensor detects the tension condition in real time and feeds the tension condition back to the magnetic powder brake; a first servo motor on the feeding clamping mechanism provides a tension force power source for feeding the film roll, the film roll is clamped by the pneumatic clamping mechanism, and the film roll is driven by the first servo motor to advance for a certain distance; and the magnetic powder brake is used for comprehensive control.

3) The air blowing nozzle and the first air clamp clamping mechanism are arranged: after the last membrane is cut, the air tap of the air blowing module blows air to play a role in guiding the position of the membrane, and the clamping mechanism is convenient to align and clamp. After the clamping mechanism clamps the membrane, the air nozzle is closed. And a pneumatic clamping (for example, a first air clamp) mechanism arranged between the tool rest and the photoelectric position detector clamps two ends of the film roll to prevent the film roll from going back due to the pulling force of the magnetic powder brake on the material rest.

Wherein, the first air clamp and the second air clamp are used for clamping two ends of the film roll and are only arranged at different positions. The first air clamp is in front of the tool holder and the second air clamp is below the tool holder. The feeding clamping mechanism needs to clamp two ends of the membrane and draw the membrane to a transverse cutting preset position, and then the cutter frame moves downwards for cutting. The position space of the second air clamp during ascending is overlapped with the position space of the clamping mechanism, so that the film clamping space of the feeding clamping mechanism is reserved for avoiding, and the space must be avoided. When the cutting is carried out, the position of the lower end of the membrane which is kept away from the space is not fastened by a mechanism, so that the two ends of the membrane are fastened by arranging a movable second air clamp.

4) And a knife rest part: after the feeding clamping mechanism clamps the diaphragm in place, the tool rest of the rodless cylinder presses downwards, and after the second air clamps below two ends of the tool rest press upwards and clamp the diaphragm, the cutter completes a cutting stroke under the driving of the rodless cylinder. And then the tool rest and the film clamping module return.

5) And a movable trough: a movable trough is arranged below the membrane discharge port and used for receiving the longitudinally cut membrane.

From this, through silo during the crosscut, the physiosis axle during rip cutting, receive holding and fastening processing to the diaphragm after the cutting, can avoid on the one hand influencing follow-up cutting because the piling up of the diaphragm after the cutting, on the other hand has removed the man-hour of processing the diaphragm in unison again after the cutting from, and is humanized good, and the reliability is high.

In an alternative example, the feeding mechanism 20 may be used to load the roll of film and deliver the roll of film to any of the cutting mechanisms 10.

From this, through feeding mechanism loading and carry the membrane book, can be so that more smooth and easy to the cutting of membrane book, be favorable to promoting cutting efficiency, reduce the cutting cost.

Optionally, the number of the feeding mechanisms 20 is more than one.

Optionally, when the number of the feeding mechanisms 20 is one, the transverse cutting mechanism 12 and the longitudinal cutting mechanism 14 are respectively adapted to be disposed on two sides of one feeding mechanism 20, so as to realize transverse cutting or longitudinal cutting of one film roll.

Optionally, when the number of the feeding mechanisms 20 is two, the transverse cutting mechanism 12 and the longitudinal cutting mechanism 14 are respectively and adaptively arranged on the two feeding mechanisms 20, so as to realize transverse cutting of one film roll and longitudinal cutting of the other film roll.

Therefore, the hardware cost can be saved and the switching control mode is simple and convenient by adapting the transverse cutting mechanism and the longitudinal cutting mechanism through one feeding mechanism; the two feeding mechanisms are respectively matched with the transverse cutting mechanism and the longitudinal cutting mechanism, so that the cutting efficiency can be improved, and the control mode of simultaneous control is reliable.

Alternatively, the feeding mechanism 20 may include: the material rack, the air expansion shaft, the first servo motor and the screw rod.

In an alternative embodiment, the inflatable shaft, which is adapted to be mounted on the stack, may be used to load the roll of film into a roll.

In an optional specific example, the material rest is mounted on the screw rod in an adaptive manner, and can be driven by the screw rod to move left and right.

In an optional specific example, the screw rod is adapted to the first servo motor, and may be driven by the first servo motor to move.

In an optional specific example, the first servo motor is adapted to the control mechanism 30, and can be used for controlling the lead screw to drive the material rack to move left and right under the control of the control mechanism 30, so as to control the alignment position between the film roll and the cutting mechanism 10 to be corrected by controlling the left and right positions of the material rack.

From this, through the adaptation setting of work or material rest, roller bearing, first servo motor and lead screw, can realize loading, transport and rectifying of film book, simple structure, the reliability is high.

Optionally, the feeding mechanism 20 may further include: a magnetic powder brake.

In an alternative embodiment, the magnetic powder brake, which is respectively adapted to the material rack and the control system, can be used to adjust the tension and/or feeding speed of the film roll during cutting by controlling the material rack under the control of the control mechanism 30.

Therefore, the magnetic powder brake can control the tension and the feeding speed when the film roll is cut, the control mode is simple and convenient, and the control reliability is high.

In an alternative example, the control mechanism 30 is respectively matched with more than two cutting mechanisms 10 and feeding mechanisms 20; can be used for controlling any cutting mechanism 10 and the feeding mechanism 20 so as to realize the cutting of the film roll by any cutting mode.

For example: one set of system can integrally control the regulation and control of various parameters under two process modes.

Therefore, by uniformly controlling the more than two cutting mechanisms and the feeding mechanism, the switching control of any one cutting mode of the more than two cutting modes can be realized, and the cutting device is good in control simplicity and high in reliability.

Alternatively, the control mechanism 30 may include: at least one control module 32 of MCU, DSP processor, PLC controller.

and 11, when the cutting mechanism 10 can comprise a photoelectric deviation-rectifying sensor, detecting the position information of the film roll on the feeding mechanism 20 through the photoelectric deviation-rectifying sensor.
