The working process of the present invention is described below with reference to fig. 1 and 2:

firstly, preparation work:

and starting a power supply of the main control box, and inputting the weight needing to be cut into the glue, namely a preset weight value and a glue cutting mode (comprising a weight feedback glue cutting mode and a length feedback glue cutting mode) on a touch screen of the main control box. At this time, the cutting mechanism 26 and the rubber section conveying mechanism are located at the initial positions; the material pressing electric cylinder is also positioned at the initial position; the rubber cutting cylinder 262 is positioned at the top dead center position; the length detection photovoltaic module 33 is located at its initial position.

Secondly, the working process of the first glue cutting mode is as follows: selecting weight feedback rubber cutting mode

1. Starting the extruder;

2. the rubber material 7 is extruded from the outlet of the extruder, and drives the front driven roller 16 of the material receiving section to rotate, so as to drive the rotary encoder 15 thereon to rotate, and signals are fed back to the programmable logic controller PLC1 of the main control box, so that an extrusion speed V1 is obtained.

3. The rubber compound 7 continues to move backwards, the first material feeding sensor 13 obtains signals, and starting signals are sent to the driving roller 226 and the driving roller 246 of the rubber cutting section, the driving roller 36 of the weighing conveying section and the driving roller 46 of the packaging buffer section through the programmable logic controller PLC1 and the programmable logic controller PLC2, and the signals can be received by the speed signal of the rotary encoder 15, so that the four driving rollers are started to operate and have the speed of V1;

4. when the sizing material 7 moves to the position of the second feeding sensor 23, a feeding signal is sent to the material pressing electric cylinder 27 of the cutting mechanism 26, the material pressing electric cylinder 27 moves downwards, and when the material pressing detection sensor 292 detects the sizing material (for example, when the sizing material is about 2cm away from the sizing material), the material pressing electric cylinder 27 stops moving downwards; preferably, it can be set that if the weighing incoming material sensor 312 does not sense the signal after 20S (the time can be set according to specific conditions), the device alarms;

5. the sizing material 7 is conveyed backwards continuously, and the weighing incoming material sensor 312 senses a signal, which indicates that the sizing material 7 normally enters the weighing conveying section; after the weighing incoming material sensor 312 senses the signal, the driving roller 226 and the driving roller 246 of the rubber cutting section stop running, and the rubber cutting driving electric cylinder 280 drives the rubber cutting conveying device and the cutting mechanism 26 to move backwards together, namely move towards the weighing conveying section, at the same speed as the moving speed of the rubber materials, namely V1;

6. when the real-time value of the weight measured by the weight sensor 31 matches the predetermined weight value (real-time value of the weight + predetermined advance = predetermined weight value), the cutting air cylinder 262 pushes the cutting wire 265 downward to cut the rubber 7. After the sizing material 7 is cut off, when the sizing material cutting cylinder 262 runs to the position of the bottom dead center, the bottom dead center sensor 268 senses a signal, the driving roller 36 of the weighing conveying section runs in an accelerated mode, the speed is twice V1, namely 2V1, the purpose of the accelerated running is to separate the cut sizing material from the original sizing material, and the next operation is executed; after the bottom dead center sensor 268 senses the signal, the driving roller 226 and the driving roller 246 of the rubber cutting segment both operate at 3 times of V1, i.e. 3V1, and the cutting mechanism 26 rapidly returns to the initial position at the reverse speed of 2V1 along with the rubber cutting and conveying device, however, the 3V1 and 2V1 mentioned here can be adjusted as required in other embodiments as long as the difference between the two can ensure that the rubber 7 can also convey the rubber backwards at the speed of V1 in the process; after the initial position is reached, the driving roller 226 and the driving roller 246 of the rubber cutting section resume the forward running at the speed V1, and the rubber cutting driving electric cylinder 280 stops;

7. when the cut rubber material reaches the position of the compound weighing sensor 314, the driving roller 36 of the weighing conveying section is stopped, static compound weighing is carried out (the compound weighing time is 2S for example), and a real weight value is obtained, so that the main control box can obtain a difference value between the real weight value and a preset weight value for adjusting the preset advance, and through the algorithm, the metering and weighing of the rubber material are more and more accurate, namely the real weight value approaches to the preset weight;

8. after the re-weighing is finished, the driving roller 36 of the weighing conveying section and the driving roller 46 of the packaging buffer section run at an accelerated speed which is twice the speed of V1, namely 2V1, although the 2V1 mentioned here can be changed in other embodiments as long as no cut rubber blocks (not shown) are on the weighing conveying section before the new end of the rubber is contacted with the weighing conveying section, and the rubber blocks flow to the next process after passing through the packaging buffer section;

9. after the sizing material is cut off and the new end of the sizing material is detected by the second feeding sensor 23, if the weighing feeding sensor 312 does not sense the signal after 20S (the time can be set according to specific conditions), the device alarms; then the new end of the sizing material is sensed by the weighing material sensor 312, at this time, the driving roller 226 and the driving roller 246 of the material cutting and conveying section stop running, and the cutting driving electric cylinder 280 drives the cutting mechanism 26 to move backwards at the same speed as the moving speed of the sizing material 7, namely V1;

10. when the weight real-time value measured by the weight sensor 31 is matched with the preset weight value, the material pressing electric cylinder 27 moves downwards to press the rubber material 7, and the rubber cutting air cylinder 262 pushes the cutting steel wire 265 to move upwards for cutting, so that the second rubber cutting is completed (the rubber is cut upwards at this time, and the rubber is cut downwards at the last time);

11. after the sizing material is cut off, the sizing material cutting cylinder 262 is sensed by the upper stop point sensor 266, the material pressing electric cylinder 27 moves to the initial position, and the sizing material 7 is loosened; meanwhile, the driving roller 36 of the weighing and conveying section runs at an accelerated speed which is twice the speed of V1 (namely 2V 1), the purpose of running at an accelerated speed is still to separate cut rubber materials from raw rubber materials, and the next operation is carried out; after the glue is cut, the driving roller 226 and the driving roller 246 of the glue cutting segment are operated at three times V1, namely 3V1, and the electric cylinder 280 of the glue cutting driving device drives the glue cutting conveying device and the cutting mechanism 26 to rapidly return to the initial position at the reverse speed of 2V1, wherein the speeds are set so that the annular conveying belt 224 and the annular conveying belt 244 on the glue cutting conveying device can convey the glue 7 backwards at the speed of V1 during the resetting process; after returning to the initial position, the driving roller 226 and the driving roller 246 are operated in the forward direction at the speed V1, and the electric cylinder 280 for driving the rubber cutting is stopped;

12. when the cut rubber material block reaches the position of the compound weighing 314, the annular conveying belt 34 of the weighing conveying section stops running, and static compound weighing is carried out (compound weighing time is 2S for example) to obtain a weight true value; and the main control box obtains the difference value between the actual weight value and the preset weight value again for adjusting the preset advance so that the actual weight value of the subsequently cut rubber block tends to the preset weight value again.

13. After the re-weighing is finished, the driving roller 36 of the weighing and conveying section and the driving roller 46 of the packaging buffer section are accelerated again at a speed of twice V1, i.e. 2V1, although the 2V1 mentioned here can be changed in other embodiments as long as it is ensured that no cut pieces of glue (not shown) are present on the weighing and conveying section before the new end of the glue comes into contact with the weighing and conveying section; the cut rubber blocks flow to the next process after passing through the packaging buffer section;

14. the two times of rubber cutting are a cycle, the first time of downward cutting and the second time of upward cutting, and then the rubber cutting cycle process is repeated.

15. Any one safety cover shell is opened in the glue cutting process, and the production line is stopped to play a role in protection.

And thirdly, working process of the second glue cutting mode: method for feeding back and cutting rubber by selecting length

When the length feedback glue cutting mode is selected, the length detection photoelectric module 33 moves to a corresponding position, and the length feedback glue cutting mode also needs to set a preset weight value of a glue block to be cut;

1. starting the extruder;

2. extruding the rubber material 7 from an outlet of the extruder, driving a front driven roller 16 of the material receiving section to rotate, driving a rotary encoder 15, and obtaining an extrusion speed V1 through program calculation;

3. the glue stock 7 continues to move backwards, the first incoming material sensor 13 receives signals and sends starting signals to the driving roller 226 and the driving roller 246 of the glue cutting section, the driving roller 36 of the weighing conveying section and the driving roller 46 of the packaging buffer section, and the starting signals can all receive speed signals of the rotary encoder 15, and the speeds of the driving rollers are all V1;

4. when the rubber material 7 moves to the second incoming material sensor 23, a feeding signal is sent to the pressing electric cylinder 27, the pressing electric cylinder 27 moves downwards, and when the pressing detection sensor 292 detects the rubber material (for example, about 2cm from the rubber material), the pressing electric cylinder 27 stops; if the length detection photovoltaic module 33 does not sense a signal after 20S (time can be set according to specific conditions), the device alarms;

5. the sizing material 7 is conveyed backwards continuously, and the first sensor 35 of the length detection photoelectric module 33 senses a signal, which indicates that the sizing material 7 is close to a preset length value; after the sensing signal is sensed, the driving roller 226 and the driving roller 246 of the material cutting section stop running, and the rubber cutting driving electric cylinder 280 drives the rubber cutting conveying device and the cutting mechanism to move backwards together at the same speed as the moving speed of the rubber materials, namely V1;

12. when the cut rubber block reaches the position of the compound weighing sensor 314, the operation of the annular conveyer belt 34 of the weighing conveying section is stopped, and static compound weighing is carried out (compound weighing time is 2S for example) to obtain the weight true value. The main control box obtains the difference value between the actual weight value and the preset weight value again, and the difference value is used for adjusting the preset length value to enable the actual weight value of the subsequently cut rubber block to tend to the preset weight value again;

13. after the re-weighing is finished, the driving roller 36 of the weighing conveying section and the driving roller 46 of the packaging buffer section run again at the accelerated speed of 2V1, and the cut rubber blocks flow to the next process after passing through the packaging buffer section;
