[0031] Please refer to Figures 1-4In use, first, the pig stomach is placed on the conveying belt 1 and conveyed forward, and the position / position of the pig stomach is detected by the sensor. When the oil net is on the upper surface of the pig stomach, the suction lifting assembly 6 at the first, third and fourth positions does not react, the electric telescopic rod 7 at the second position is started to pull the push-pull plate 10 to slide, and the arc-shaped blade 4 is controlled to rotate, and the electric push rod 16 is controlled to be started to push the connecting plate 15 to move downward, so that the trachea 13 is stretched to drive the suction cup 14 to approach and contact the oil net, and then the oil net can be sucked and lifted upward.

Similarly, when the oil net is on the right side of the pig stomach, the pig stomach is controlled to stop at the first position, and the oil net is separated. In this way, the oil net in different positions of the pig stomach can be separated by the rotary cutting transmission assembly 5 and the suction lifting assembly 6 at different positions.

[0032] An oil net separation method using the pig stomach oil net separation device in the embodiment, the steps comprising:

[0033] Step 1, when the pig stomach 20 moves along the conveying belt 1 to the first position 31, the first group of suction lifting assemblies (suction lifting assemblies located at the first position 31) are controlled to work. If the first photoelectric sensor (sensor located at the lower end of the trachea 13 above the first position 31) senses the lifted oil net, the corresponding rotary cutting transmission assembly 5 (rotary cutting transmission assembly located at the first position 31) is controlled to work, and the corresponding arc-shaped blade 4 is driven to act to cut the oil net on the pig stomach 20. After the oil net on the pig stomach 20 is cut, the oil net enters the corresponding collection chamber (the same below) from the trachea 13. If the first photoelectric sensor does not sense the lifted oil net, step 2 is directly performed.

[0034] Step 2, when the pig stomach 20 moves along the conveying belt 1 to the second position 32, the second group of suction lifting assemblies (suction lifting assemblies located at the second position 32) are controlled to work. If the second photoelectric sensor (sensor located at the lower end of the trachea 13 above the second position 32) senses the lifted oil net, the corresponding rotary cutting transmission assembly 5 (rotary cutting transmission assembly located at the second position 32) is controlled to work, and the corresponding arc-shaped blade 4 is driven to act to cut the oil net on the pig stomach 20. If the second photoelectric sensor does not sense the lifted oil net, step 3 is performed.

[0035] Step 3, according to the foregoing method, when the pig stomach 20 moves along the conveying belt 1 to the third position 33, the third group of suction lifting assemblies are controlled to work. If the third photoelectric sensor senses the lifted oil net, the corresponding rotary cutting transmission assembly 5 is controlled to work, and the corresponding arc-shaped blade 4 is driven to act to cut the oil net on the pig stomach 20. If the third photoelectric sensor does not sense the lifted oil net, step 4 is performed.

[0036] Step 4, when the stomach 20 moves along the conveying belt 1 to the fourth station 34, the fourth group of suction and pulling assemblies are controlled to work, if the fourth photoelectric sensor senses the net oil after being pulled, the corresponding rotary cutting transmission assembly 5 is controlled to work to drive the corresponding arc-shaped blade 4 to act to cut off the net oil on the stomach 20.

[0037] The technical key point in the scheme: ingeniously use the characteristics that the net oil on the outer surface of the stomach is soft and slippery and can be sucked into the trachea 13 by negative pressure, but the stomach cannot enter the trachea 13, as long as the net oil is sucked into the trachea 13, the posture of the suction and pulling assembly after sucking the net oil is similar to the posture of pulling the net oil with hands, and the stomach is located directly below the trachea 13, at this time, only need to rotate the arc-shaped blade 4 to cut off the net oil; using four groups of suction and pulling assemblies at different positions to match the stomach in different postures, can realize omnidirectional accurate capture and suction of the net oil, because the postures of the stomach entering the conveying belt 1 are different, the net oil will be located at one or two positions of front, rear, top, left side and right side of the stomach.

[0038] By using the scheme, the net oil on the outer surface of the stomach can be quickly separated, the processing efficiency of the net oil is significantly improved, and on average only half a minute is needed to separate the net oil on the outer surface of a stomach, the problem of damaging the hands of the operator is fundamentally avoided, and the net oil will not be affected by the soft and slippery characteristics during the processing process, and there is no need to spread the net oil for operation.
