[0043] Furthermore, the cutting component includes a pressing surface cylinder 8, and the pressing surface cylinder 8 is fixedly connected to the cutter support 1;

[0044] Among them, the output end of the cutter support 1 is fixedly connected to a pressing surface die 7. Multiple rectangular grooves are opened on the pressing surface die 7. Two cutter fixing brackets 13 are fixedly connected to the left and right inner walls of the cutter support 1 respectively, and the shapes of the two cutter fixing brackets 13 are concave;

[0045] Among them, multiple cutter installation grooves are opened on the two cutter fixing brackets 13 respectively, and a set of cutters 10 are slidably connected to the inner walls of the multiple cutter installation grooves;

[0046] Among them, a set of cutters 10 on the left side consists of 12 cutters 10, and a set of cutters 10 on the right side consists of 11 cutters 10. The two sets of cutters 10 are installed in a staggered manner front and back.

[0047] Furthermore, installation holes are opened on the multiple cutters 10.

[0054] Further, when using the automatic feeding and cutting device, first place the gluten on the baffle of the first gluten feeding baffle 3 through the feeding device. The second gluten feeding baffle 6 will limit the front and rear positions of the gluten. The gluten feeding infrared sensor 21 senses the gluten, and the feeding device stops feeding. At the same time, the first gluten feeding cylinder 4 and the second gluten feeding cylinder 9 are started. The first gluten feeding cylinder 4 and the second gluten feeding cylinder 9 simultaneously push the first gluten feeding baffle 3 and the second gluten feeding baffle 6 to move forward synchronously. After the first gluten feeding cylinder 4 and the second gluten feeding cylinder 9 are pushed out for 0.2 - 0.5 seconds, the second gluten feeding cylinder 9 retracts, and the second gluten feeding cylinder 9 drives the first gluten feeding baffle 3 to move backward. When the baffle on the first gluten feeding baffle 3 disengages from the second gluten feeding baffle 6, the gluten will fall onto the cutting knife 10. At the same time, after the second gluten feeding cylinder 9 retracts and the magnetic switch has a signal, the first gluten feeding cylinder 4 retracts and the pressing cylinder 8 is pushed out. The pressing cylinder 8 pushes the pressing die 7 to move downward. The pressing die 7 presses the gluten and squeezes it downward, so that the gluten passes through the middle of the two groups of cutting knives 10 to cut the gluten. At the same time, multiple cutting knives 10 will enter into multiple rectangular grooves on the pressing die 7 and continue to push the pressing die 7 to move downward. The purpose is to facilitate the connection of subsequent gluten processing. When multiple cutting knives 10 are in contact with multiple rectangular grooves, the reset pressing cylinder 8 drives the pressing die 7 to move upward. At the same time, the gluten feeding infrared sensor 21 has no signal, the magnetic switch of the first gluten feeding cylinder 4 retracting has a signal, and the feeding device is started. The magnetic switch of the pressing cylinder 8 being pushed out has a signal. After the pressing cylinder 8 stays for a certain time, the pressing cylinder 8 retracts. The magnetic switch of the pressing cylinder 8 retracting has a signal, and the next cycle starts. Repeating like this can achieve the automatic cutting of gluten. By setting the second gluten feeding baffle 6, the first gluten feeding baffle 3, the first gluten feeding cylinder 4, the second gluten feeding cylinder 9, the gluten feeding infrared sensor 21, the pressing cylinder 8, the pressing die 7 and multiple cutting knives 10, the automatic cutting of gluten can be achieved. The whole operation process is simple and convenient, improving the overall cutting efficiency when cutting a large number of gluten.

[0055] Further, when it is necessary to cut large gluten and small gluten, first loosen the cutting knife pitch locking screws 16 on the four cutting knife pitch adjustment connecting plates 15 and the fastening bolts 19 on the two cutting knife fixed connection lead screws 18. Then pull the two cutting knife fixed connection lead screws 18 to slide back and forth on the inner wall of the corresponding first knife pitch adjustment groove to adjust the relative distance between the corresponding cutting knives 10, so as to realize the depth of the knife cut when cutting the gluten. The positions of the four cutting knife pitch locking screws 16 change. By loosening the fixing bolts on the two second gluten limit baffles 14, then the relative distance between the two second gluten limit baffles 14 can be adjusted through the four adjustment grooves 17 so that the distance between them conforms to the diameter of the gluten and does not jam the gluten, so as to make both large gluten and small gluten meet the usage requirements and improve the flexibility of the automatic feeding and cutting device when in use.

[0056] Working principle: When using the automatic feeding and cutting device, first place the gluten on the baffle on the first gluten feeding baffle 3 through the feeding device. The second gluten feeding baffle 6 will limit the front and rear positions of the gluten. The feeding infrared sensor 21 senses the gluten, and the feeding device stops feeding. At the same time, the first gluten feeding cylinder 4 and the second gluten feeding cylinder 9 are started. The first gluten feeding cylinder 4 and the second gluten feeding cylinder 9 simultaneously push the first gluten feeding baffle 3 and the second gluten feeding baffle 6 to move forward synchronously. After the first gluten feeding cylinder 4 and the second gluten feeding cylinder 9 are pushed out for 0.2 - 0.5 seconds, the second gluten feeding cylinder 9 retracts, and the second gluten feeding cylinder 9 drives the first gluten feeding baffle 3 to move backward. When the baffle on the first gluten feeding baffle 3 disengages from the second gluten feeding baffle 6, the gluten will fall onto the cutting knife 10. At the same time, after the second gluten feeding cylinder 9 retracts and the magnetic switch has a signal, the first gluten feeding cylinder 4 retracts and the pressing cylinder 8 is pushed out. The pressing cylinder 8 pushes the pressing die 7 to move downward. The pressing die 7 presses the gluten and squeezes it downward, so that the gluten passes through the middle of the two groups of cutting knives 10 to cut the gluten. At the same time, multiple cutting knives 10 will enter into multiple rectangular grooves on the pressing die 7 and continue to push the pressing die 7 to move downward. The purpose is to facilitate the connection of subsequent gluten processing. When multiple cutting knives 10 are in contact with multiple rectangular grooves, the reset pressing cylinder 8 drives the pressing die 7 to move upward. At the same time, the feeding infrared sensor 21 has no signal, the first gluten feeding cylinder 4 retracts and the magnetic switch has a signal, the feeding device is started, the pressing cylinder 8 is pushed out and the magnetic switch has a signal. After the pressing cylinder 8 stays for a certain time, the pressing cylinder 8 retracts. When the pressing cylinder 8 retracts and the magnetic switch has a signal, the next cycle starts. Repeating like this can realize the automatic cutting of gluten. By setting the second gluten feeding baffle 6, the first gluten feeding baffle 3, the first gluten feeding cylinder 4, the second gluten feeding cylinder 9, the feeding infrared sensor 21, the pressing cylinder 8, the pressing die 7 and multiple cutting knives 10, the automatic cutting of gluten can be realized. The whole operation process is simple and convenient.

[0057] Furthermore, when it is necessary to cut large gluten and small gluten, first loosen the cutting knife pitch locking screws 16 on the four cutting knife pitch adjustment connecting plates 15 and the fastening bolts 19 on the two cutting knife fixed connection lead screws 18. Then pull the two cutting knife fixed connection lead screws 18 to slide back and forth on the inner wall of the corresponding first knife pitch adjustment groove to adjust the relative distance between the corresponding cutting knives 10, so as to realize the depth of the knife cut when cutting the gluten. The positions of the four cutting knife pitch locking screws 16 change. By loosening the fixing bolts on the two second gluten limit baffles 14, then the relative distance between the two second gluten limit baffles 14 can be adjusted through the four adjustment grooves 17 so that the distance between them conforms to the diameter of the gluten and does not jam the gluten, so as to make both large gluten and small gluten meet the usage requirements.
