[0023] 1. The present invention is provided with components such as a cutting knife and a torsion spring. When the cutting knife is performing cutting processing, if the hardness of the soybean fibrous protein on the conveyor belt changes, the cutting resistance of the cutting knife will change.

[0034] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0035] like Figures 1 to 7 As shown, the reciprocating cutting device of the present invention includes a machine base 1, a conveyor belt 2 is arranged on the machine base 1, a cutting assembly 3 is arranged on the upper end of the machine base 1 above the conveyor belt 2, the conveyor belt 2 is used to transport the soy fibrous protein extruded by the puffing extruder, and the cutting assembly 3 is used to cut the soy fibrous protein on the conveyor belt 2.

[0036] A protective shell 4 is arranged on both sides of the conveyor belt 2 at the upper end of the machine base 1, and a unloading plate 5 is arranged at the unloading position of the conveyor belt 2 at the upper end of the machine base 1. A motor for driving the conveyor belt 2 is arranged inside the machine base 1, and the motor is used to drive the conveyor belt 2 to operate. The soy fibrous protein cut on the conveyor belt 2 is unloaded with the assistance of the unloading plate 5, so that the soy fibrous protein can accurately enter the next process.

[0037] The cutting assembly 3 includes two support plates 301 respectively arranged on both sides of the conveyor belt 2. Tracks 312 are arranged on the upper end of the machine base 1 on both sides of the conveyor belt 2. Rollers 313 are rotatably arranged at the lower end of the support plate 301. A driving motor is arranged at the position of the rollers 313 in the support plate 301. The rollers 313 slide on the tracks 312. There are four rollers 313. The four rollers 313 are paired and arranged on both sides of the support plate 301 respectively. The track 312 passes between the upper and lower rollers 313. After the driving motor is started, the rollers 313 will rotate. When the rollers 313 rotate, the support plate 301 will move along the track 312. Four rollers 313 are installed on each support plate 301, and the four rollers 313 are paired. The track 312 passes between the two rollers 313, so that the four rollers 313 clamp the track 312, thereby making the support plate 301 more stable when moving, thereby improving the stability of the equipment.

[0038] A cross bar 302 is set up between the two support plates 301 for sliding up and down, and a plurality of sliding sleeves 303 are set on the cross bar 302. A groove 304 is set at the lower end of the sliding sleeve 303, and a cutting knife 305 is set in the groove 304. The cutting knife 305 is rotatably connected to the sliding sleeve 303 through a torsion spring. When the support plate 301 moves along the direction of the track 312, the cross bar 302 will also move accordingly. When the cross bar 302 moves, the cutting knife 305 will move along the conveyor belt 2 with the assistance of the sliding sleeve 303. The cutting knife 305 will cut the soy fibrous protein on the conveyor belt 2 during the movement, and the cross bar 302 can slide up and down to adjust the cutting depth of the cutting knife 305.

[0039] A limiting slide rail 318 is set on the side where the two support plates 301 are close to each other, and limiting sliders 319 are set on both sides of the cross bar 302. The limiting sliders 319 slide on the limiting slide rail 318. A hydraulic cylinder 320 is set on one side of the limiting slide rail 318 of the support plate 301, and the output end of the hydraulic cylinder 320 is set at the lower end of the limiting slider 319. After the hydraulic cylinder 320 is started, the output end of the hydraulic cylinder 320 drives the limiting slider 319 to move along the limiting slide rail 318, thereby making the cross bar 302 rise and fall. The lifting and lowering of the cross bar 302 can adjust the cutting depth of the cutting knife 305.

[0040] A limiting hole 321 is provided on the sleeve 303, and the cross bar 302 passes through the limiting hole 321. A threaded hole 322 is provided at the upper end of the limiting hole 321 of the sleeve 303, and a fixing bolt 323 is provided in the threaded hole 322. The sleeve 303 can move along the cross bar 302. After the sleeve 303 moves to the position, the fixing bolt 323 is rotated to fix the position of the sleeve 303, so that the cutting position of the soy fibrous protein can be adjusted.

[0041] During the use of the present invention, the soy fibrous protein extruded by the puffing extruder falls on the conveyor belt 2, and the motor is started. After the motor is started, the conveyor belt 2 is operated, and the conveyor belt 2 transports the soy fibrous protein. During the movement of the soy fibrous protein, the soy fibrous protein will pass through the cutting knife 305.

[0042] At this time, the hydraulic cylinder 320 is started, and the output end of the hydraulic cylinder 320 drives the limit slider 319 to descend. When the limit slider 319 descends along the limit slide rail 318, it will drive the cross bar 302 to descend, so that the cutting knife 305 descends to adjust the cutting depth of the cutting knife 305, ensuring that the cutting knife 305 can completely cut the soy fibrous protein on the conveyor belt 2.

[0043] At this time, the driving motor can be started to rotate the roller 313. The rotation of the roller 313 will slide along the track 312, so that the cross bar 302 will slide along the track 312. The movement of the cross bar 302 will move the cutting knife 305. When the moving direction of the cutting knife 305 is opposite to the moving direction of the conveyor belt 2, the cutting effect of the cutting knife 305 will be better.

[0044] At the same time, the sleeve 303 can move along the cross bar 302, and can be fixed on the cross bar 302 with the assistance of the fixing bolt 323. By adjusting the positions of multiple sleeves 303, the cutting position of the cutting knife 305 can be adjusted to change the cutting width of the soy fibrous protein, thereby improving the convenience of equipment processing.

[0045] When the extruder extrude the soy fibrous protein, the hardness of the soy fibrous protein will be affected by the processing temperature, and there will be impurities in the soy fibrous protein. Due to the change in the hardness of the soy fibrous protein and the influence of the impurities inside, the cutting effect of the cutting knife 305 will be deteriorated, and it is even easy to cause damage to the cutting knife 305. When the cutting knife 305 cuts, impurities are easy to adhere to the cutting knife 305. Therefore, we propose the following solution for improvement.

[0046] like Figures 1 to 7As shown, a vibration plate 306 is provided at the lower end of the cross bar 302 on the outer side of the sliding sleeve 303, a limit block 307 is slidably provided on the side of the vibration plate 306 close to the sliding sleeve 303, a spring 308 is provided between the limit block 307 and the sliding sleeve 303, a push rod 309 is provided on the side of the limit block 307 close to the sliding sleeve 303, the push rod 309 passes through the sliding sleeve 303 and enters the groove 304, a pressure sensor is provided on the side of the cutting knife 305 close to the push rod 309, a knocking rod 310 is provided at the side end of the vibration plate 306 between the two support plates 301, and an eccentric wheel 311 is provided on the knocking rod 310. Due to the presence of the torsion spring, when the cutting knife 305 encounters a hard object during cutting, the cutting resistance of the cutting knife 305 increases, so the cutting knife 305 will move in the moving direction of the conveyor belt 2 The cutting knife 305 will deflect, and the cutting knife 305 will contact the push rod 309 after the deflection, and the pressure sensor can detect the pressure of the push rod 309 on the cutting knife 305. The larger the detection value of the pressure sensor, the greater the degree of deflection of the cutting knife 305, that is, the greater the hardness of the hard object encountered by the cutting knife 305 during cutting. At this time, the driving motor is started to rotate the roller 313, which drives the first transmission wheel 314 to rotate, and then drives the second transmission wheel 315 to rotate, and then drives the eccentric wheel 311 on the knocking rod 310 to rotate, so that the vibration plate 306 vibrates, and the vibration of the vibration plate 306 causes the push rod 309 to vibrate, and the vibration of the push rod 309 is transmitted to the cutting knife 305, and the vibration of the cutting knife 305 is conducive to the cutting of the cutting knife 305.

[0047] A first transmission wheel 314 is provided on the side of the roller 313 away from the support plate 301, a second transmission wheel 315 is provided on the side end of the knocking rod 310 above the first transmission wheel 314, a transmission belt 316 is provided between the first transmission wheel 314 and the second transmission wheel 315, a stabilizing plate 317 is provided on the side of the support plate 301 close to the knocking rod 310, the knocking rod 310 is rotatably arranged on the stabilizing plate 317, when the roller 313 rotates, the rotation of the roller 313 drives the rotation of the first transmission wheel 314, the rotation of the first transmission wheel 314 drives the rotation of the second transmission wheel 315 with the assistance of the transmission belt 316, the rotation of the second transmission wheel 315 drives the rotation of the knocking rod 310, the rotation of the knocking rod 310 drives the rotation of the eccentric wheel 311, and when the eccentric wheel 311 rotates, it knocks the vibration plate 306, thereby causing the vibration plate 306 to vibrate.

[0048] Rubber sleeves 324 are provided on both sides of the cross bar 302, and the vibration plate 306 is provided at the lower end of the rubber sleeve 324. An auxiliary track 325 is provided on the side of the vibration plate 306 close to the sliding sleeve 303, and the limit block 307 slides on the auxiliary track 325. When the vibration plate 306 vibrates, due to the assistance of the rubber sleeve 324, the vibration of the vibration plate 306 will not be transmitted to the cross bar 302, so that the use of the cross bar 302 is more stable. The auxiliary track 325 is used to limit the limit block 307, thereby improving the stability of the equipment.

[0049] During the use of the present invention, as the conveyor belt 2 runs, the soy fibrous protein on the conveyor belt 2 also moves and is cut by the cutting knife 305. If the hardness of the soy fibrous protein on the conveyor belt 2 increases or impurities are present, when the soy fibrous protein passes through the cutting knife 305, the increased hardness of the soy fibrous protein or the influence of the impurities inside will increase the cutting resistance of the cutting knife 305, thereby causing the cutting knife 305 to deflect in the direction of the movement of the soy fibrous protein, and the deflection of the cutting knife 305 will trigger an increase in the torsion of the torsion spring, thereby allowing the cutting knife 305 to generate pressure on the soy fibrous protein, thereby making the cutting of the cutting knife 305 smoother.

[0050] When the deflection of the cutting knife 305 reaches the threshold, the side end of the cutting knife 305 will contact the top rod 309, so that the pressure sensor starts to detect the pressure value. When the detection value of the pressure sensor starts to rise, it indicates that the torsion force of the torsion spring alone can no longer meet the smooth cutting of the cutting knife 305. At this time, the device controls the drive motor in the support plate 301 to start, so that the roller 313 rotates. The rotation of the roller 313 causes the support plate 301 to move along the track 312, thereby causing the cross bar 302 to move in the opposite direction of the conveyor belt 2, so that the movement direction of the cutting knife 305 is aligned with the conveyor belt 2. The moving direction of the conveyor belt 2 is opposite, so that the cutting knife 305 has a stronger cutting ability to cut the soy fibrous protein on the conveyor belt 2. At the same time, due to the deflection of the cutting knife 305, the cutting depth of the lower end of the cutting knife 305 becomes shallower. Therefore, when the detection value of the pressure sensor gradually increases, the equipment controls the hydraulic cylinder 320 to start, and the output end of the hydraulic cylinder 320 drives the limiting slider 319 to descend, so that the cross bar 302 moves downward, and then the cutting depth of the cutting knife 305 is reduced, ensuring that the cutting knife 305 can completely cut the soy fibrous protein on the conveyor belt 2.

[0051] When the roller 313 rotates, the rotation of the roller 313 will also drive the rotation of the first transmission wheel 314. The rotation of the first transmission wheel 314 will drive the rotation of the second transmission wheel 315 through the transmission belt 316. The rotation of the second transmission wheel 315 will drive the rotation of the knocking rod 310. The rotation of the knocking rod 310 will drive the rotation of the eccentric wheel 311. The rotation of the eccentric wheel 311 will knock on the vibration plate 306, thereby causing the vibration plate 306 to vibrate. The vibration of the vibration plate 306 will drive the vibration of the push rod 309 through the limit block 307. At this time, the cutting knife 305 is in contact with the push rod 309, so the cutting knife 305 will also vibrate accordingly. The vibration of the cutting knife 305 is conducive to cutting the soybean fibrous protein on the conveyor belt 2, and the vibration of the cutting knife 305 will also shake off the impurities adhering to the cutting knife 305.

[0052] When the cutting knife 305 is cutting, the cutting knife 305 will exert pressure on the soy fibrous protein, which makes it easy for the soy fibrous protein to adhere to the conveyor belt 2. After the soy fibrous protein on the conveyor belt 2 is cut, the hydraulic cylinder 320 is started, and the output end of the hydraulic cylinder 320 drives the limit slider 319 to descend, so that the cross bar 302 is lowered, so that the lower end of the cutting knife 305 contacts the conveyor belt 2. Since the descending distance of the cross bar 302 is large and the conveyor belt 2 keeps running, the cutting knife 305 is in an inclined state at this time. The conveyor belt 2 is made of metal. Then the driving motor is started to rotate the roller 313. Thereby, the cutting knife 305 moves along the conveyor belt 2. During the movement, due to the resistance of the conveyor belt 2, the cutting knife 305 will contact the top rod 309 and vibrate. On the one hand, the vibration of the cutting knife 305 itself will clean the impurities on the cutting knife 305. On the other hand, the vibration of the cutting knife 305 will cause the cutting knife 305 to swing slightly, so that the cutting knife 305 scrapes off the impurities adhered to the cutting position on the conveyor belt 2, thereby completing the cleaning of the conveyor belt 2. By driving the motor to run forward and reverse, the cutting component 3 performs reciprocating cleaning to ensure that the conveyor belt 2 can be completely cleaned.

[0053] The main functions realized by the present invention are: with the assistance of the cutting knife 305, the soybean fibrous protein on the conveyor belt 2 can be cut and processed, and when the hardness of the soybean fibrous protein changes or impurities are present, the deflection of the cutting knife 305 can be detected by the pressure sensor, so that the driving motor is started, and the cutting component 3 is moved along the conveyor belt 2. When the cutting component 3 moves, the eccentric wheel 311 rotates and strikes the vibration plate 306, so that the cutting knife 305 vibrates, making the cutting of the cutting knife 305 smoother, and the moving direction of the cutting component 3 is opposite to the moving direction of the soybean fibrous protein, so that the cutting effect of the cutting knife 305 is better. At the same time, due to the vibration of the cutting knife 305, the impurities adhered to the cutting knife 305 will also be shaken off, and the cutting knife 305 can also scrape and clean the impurities adhered to the cutting position on the conveyor belt 2, thereby improving the effect of equipment use.

[0054] The present invention also provides a cutting method of a reciprocating cutting device, comprising the following steps:

[0055] Step 1: First, the soy fibrous protein extruded by the puffing extruder is conveyed to the conveyor belt 2, and the motor in the machine is started to make the conveyor belt 2 run.

[0056] Step 2: Start the cutting assembly 3 to make the cutting knife 305 in the cutting assembly 3 descend to the cutting position. As the conveyor belt 2 runs, the soy fibrous protein on the conveyor belt 2 will be cut when passing through the cutting knife 305.

[0057] Step three: Detect the state of the cutting knife 305 through the pressure sensor, and control the driving motor to operate according to the detection result of the pressure sensor, so that the cutting component 3 moves and the cutting ability of the cutting knife 305 is enhanced.

[0058] Step 4: After the cutting is completed, the cutting assembly 3 is controlled accordingly so that the lower end of the cutting knife 305 is attached to the conveyor belt 2, and the cutting assembly 3 is driven by the driving motor to reciprocate on the track 312 to clean the cutting knife 305 and the conveyor belt 2.

[0059] The invention also provides an application of a reciprocating cutting device in the field of food processing.
