Description

Technical Field

[0001] This invention relates to the cutting and processing technology of tuber raw materials, and in particular to an adaptive directional cutting device and method for cutting tuber raw materials such as sweet potato tubers into strips along the length direction with low loss and low breakage. Background Technology

[0002] Sweet potatoes and other tuberous raw materials typically require slicing / stripping during processing into various products. Most existing slicing / stripping equipment uses centrifugal cutting to first slice and then cut into strips. Due to centrifugal force, the material experiences excessive impact during the slicing process, resulting in a high breakage rate after cutting. This is especially true for sweet potatoes, whose tubers are inherently brittle and prone to cracking, leading to an extremely high breakage rate during mechanical cutting. Therefore, manual cutting is often used in actual processing to avoid excessive breakage and waste. Furthermore, centrifugal mechanical cutting makes it difficult to cut long strips along the length of the tuber, resulting in low yield and a limited number of high-grade products. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an adaptive directional slicing device and method for tuber raw materials, in order to address the above-mentioned defects of the prior art, and solve the problems of high material breakage rate, difficulty in slicing into strips according to the length direction of the material, and poor cutting surface quality faced by tuber raw materials such as sweet potatoes, especially sweet potatoes and fresh potato tubers, during mechanical cutting.

[0004] To achieve the above objectives, the present invention provides an adaptive directional slicing device for potato raw materials, comprising:

[0005] frame;

[0006] A feed hopper is installed on the frame, and a serpentine guide tapering groove is provided inside the feed hopper;

[0007] The slicing mechanism is located on the frame corresponding to the outlet of the feed hopper. The slicing mechanism includes a slicing drive mechanism, a slicing disc, and a slicing blade. The slicing drive mechanism is mounted on the frame and connected to the slicing disc via a vertical drive shaft. The slicing disc is a vertical blade position horizontal rotation cutting structure and forms a slicing working area together with the outlet of the serpentine guide tapering groove. The slicing blade is mounted on the slicing disc and located above the slicing working area.

[0008] A belt conveyor mechanism is installed on the frame and located below the slicing disc. It is used to convey the sheet material cut by the slicing mechanism and adjust the length direction of the sheet material to be consistent with the conveying direction.

[0009] A clamping and cutting mechanism, mounted on the frame at the end corresponding to the belt conveyor mechanism, is used to cut the sheet material into strips; and

[0010] The discharge hopper is mounted on the frame, corresponding to the clamping and cutting mechanism.

[0011] The aforementioned adaptive directional slicing device for potato raw materials further includes a connecting slider for connecting the belt conveyor mechanism and the slicing clamping mechanism, ensuring that the sheet material smoothly enters the slicing clamping mechanism along its length.

[0012] The aforementioned adaptive directional slicing device for potato raw materials, wherein the belt conveyor mechanism is a guide belt conveyor structure, comprising:

[0013] A conveying drive mechanism is mounted on the frame;

[0014] The drive shaft is connected to the conveying drive mechanism and is located at the discharge end;

[0015] The driven shaft is mounted on the frame and located at the feed end via an outer spherical sliding bearing seat. The drive shaft and the driven shaft are connected by a conveyor belt. Guide grooves are provided on the hubs of both the drive shaft and the driven shaft, and these guide grooves engage with the guide belt on the transmission belt.

[0016] A conveyor guide trough is disposed above the transmission belt to adjust the sheet material to be aligned with the conveying direction along its length.

[0017] In the aforementioned adaptive directional slicing device for potato raw materials, the conveying guide trough is a U-shaped trough made of thin steel plate. The bottom width of the U-shaped trough gradually narrows from the feeding end to the discharge end, and the outlet width of the discharge end of the U-shaped trough is equal to the diameter of the serpentine tapering tube.

[0018] The aforementioned adaptive orientation slicing device for potato raw materials, wherein the slicing clamping mechanism includes:

[0019] Idler rollers, mounted on the frame; and

[0020] The slicing roller is mounted on the frame corresponding to the support roller and is connected to the drive shaft through the slicing transmission mechanism. The slicing roller and the support roller mesh and rotate in opposite directions at the same linear speed to complete the slicing action.

[0021] The aforementioned adaptive orientation slicing device for potato raw materials, wherein the slicing roller comprises:

[0022] The mandrel is connected to the conveying drive mechanism via the strip cutting transmission mechanism;

[0023] Multiple disc cutters are respectively mounted on the mandrel, and the mandrel transmits power to drive the disc cutters to rotate and perform cutting.

[0024] Multiple spacers are mounted on the mandrel and positioned between adjacent disc cutters, the spacers having an equal width equal to the width of the strip material; and

[0025] A clamping plate is mounted on the mandrel and locks the disc cutter and spacer plate axially.

[0026] In the aforementioned adaptive directional slicing device for potato raw materials, the blade of the disc cutter is serrated, the blade tooth depth of the disc cutter is 3-5 mm, and the spacing between adjacent disc cutters is 5-10 mm.

[0027] In the aforementioned adaptive orientation slicing device for potato raw materials, the surface of the idler roller is provided with a plurality of grooves corresponding to the disc cutter, and the spacing between adjacent grooves is equal and equal to the width of the strip material.

[0028] The aforementioned adaptive orientation slicing device for potato raw materials further includes an arc-shaped comb, which is mounted on the frame corresponding to the slicing roller. The width of the arc teeth of the arc-shaped comb is smaller than the width of the spacer plate, and the leading edge of the arc teeth is in close contact with the circumferential surface of the spacer plate.

[0029] In the aforementioned adaptive directional slicing device for tuber raw materials, the cross-section of the serpentine guide tapering channel is circular, and the diameter of the serpentine guide tapering channel is larger than the diameter of the tuber material and smaller than the length of the tuber material.

[0030] The aforementioned adaptive orientation slicing device for potato raw materials includes a slicing mechanism that further comprises a slicing thickness adjustment plate mounted on the slicing blade disc. By adjusting the slicing thickness adjustment plate, slicing of sheet materials of different thicknesses can be achieved.

[0031] In the aforementioned adaptive directional slicing device for potato raw materials, the slicing blade is a flat blade with a cutting angle of 9°, the cutting edge of the slicing blade forms a 25° angle with the radial direction of the slicing blade disc, and the sliding angle of the slicing blade during cutting is 25°.

[0032] To better achieve the above objectives, the present invention also provides an adaptive orientation slicing method for potato raw materials, comprising the following steps:

[0033] S100: The tuber material enters from the feed hopper inlet and randomly enters the serpentine guide tapering trough. Under the action of gravity, it slides along the conveying serpentine guide tapering trough to the outlet of the trough and enters the slicing working area of ​​the slicing mechanism.

[0034] S200, the tuber material is oriented and fixed on the upper arc surface of the serpentine guide tapering groove, and the slicing mechanism performs slicing operation to cut the tuber material into slices;

[0035] S300, the sheet material falls into the belt conveyor mechanism at the bottom of the slicing mechanism, and the belt conveyor mechanism adjusts the direction of the sheet material before conveying it to the clamping and cutting mechanism, wherein the length direction of the sheet material is consistent with the conveying direction; and

[0036] S400, the clamping and cutting mechanism cuts the sheet material into strip material, and the strip material is peeled out by the arc-shaped comb and enters the discharge hopper, completing the adaptive orientation cutting.

[0037] The technical advantages of this invention are as follows:

[0038] 1) Achieved low-damage, low-breakage mechanical slicing: The slicing blade with a 9° cutting angle and a 25° sliding angle effectively reduces the cutting resistance of tuberous materials, thereby reducing the impact force during the slicing process; the slicing speed and strip cutting speed are controlled separately by independent motors and power transmission mechanisms, realizing a low-speed, flexible slicing process that mimics manual cymbal cutting, avoiding the impact breakage caused by high-speed cutting during centrifugal slicing; the surface-grooved connecting slider and arc-shaped comb structure ensure that sheet materials can be smoothly and with low damage along the length direction. Therefore, by adjusting the slicing speed, strip cutting speed and their coordination, low-damage, low-breakage cutting along the length direction can be achieved for different materials and their characteristics.

[0039] 2) Adaptive guiding slicing operation is achieved: The serpentine guide tapering tube sorts the tuberous material along its length into the working area on the slicing disc, thus ensuring that the sheet material has the same orientation during continuous slicing; The slicing mechanism and the clamping and slicing mechanism are connected by a belt conveyor and a conveyor guide plate, which not only ensures the independence and individual adjustment between the slicing mechanism and the clamping and slicing mechanism, but also realizes the directional conveying of sheet material, thereby achieving adaptive guiding slicing;

[0040] 3) Enables batch production of straight strips in various specifications and sizes: The vertical blade position and horizontal rotation slicing method of the slicing mechanism not only reduces impact breakage, but also produces flat slices, eliminating the arc-shaped surface produced by centrifugal slicing / strip machines. Therefore, the shaped strips are straight, eliminating defects such as diamond-shaped arc strips. At the same time, by replacing the slicing thickness adjustment plate and the spacer plate on the slicing roller, various sizes of slicing strips can be achieved to meet the diverse needs of tuber raw materials. Both the slicing mechanism and the clamping and slicing mechanism adopt dual-station continuous operation, which improves the overall slicing efficiency and realizes diversified and continuous large-scale slicing processing.

[0080] The structural and working principles of the present invention will be described in detail below with reference to the accompanying drawings:

[0081] This invention targets brittle and easily broken tuber materials such as sweet potatoes. By independently controlling the slicing and strip-cutting speeds, and employing guided feeding, vertical flexible slicing, adjustable conveying troughs, and cutter roller clamping of the strips, it achieves tuber cutting processing that mimics manual cymbal cutting, adaptively guides the cutting of long strips, and reduces the breakage rate.

[0082] See Figures 1-3 , Figure 1 This is a schematic diagram of the adaptive orientation slitting device according to an embodiment of the present invention. Figure 2 This is a partial cross-sectional view of the slicing mechanism 3 according to an embodiment of the present invention. Figure 3 This is a partial top view of the slicing mechanism 3 according to an embodiment of the present invention. The adaptive directional slicing device for potato raw materials of the present invention includes: a frame 1; a feed hopper 2 mounted on the frame 1, the feed hopper 2 having a serpentine guide tapering groove 21; and a slicing mechanism 3 for slicing potato tubers into slices and positioning them on a conveyor belt at a certain angle. The outlet of the feed hopper 2 is located on the frame 1. The slicing mechanism 3 includes a slicing drive mechanism 34, a slicing disc 32, and slicing blades 31. The slicing drive mechanism 34 is mounted on the frame 1 and connected to the slicing disc 32 via a vertical drive shaft 35. The slicing disc 32 is a vertical blade position horizontal rotation cutting structure and, together with the outlet of the serpentine guide tapering groove 21, forms a slicing working area. The slicing blade 31 is mounted on the slicing blade disc 32 and located above the slicing working area; the belt conveyor mechanism 4 is mounted on the frame 1 and located below the slicing blade disc 32, used to convey the sheet material to the clamping and cutting mechanism 6, and to give the sheet material 9 a certain initial cutting speed, that is, to convey the sheet material 9 cut by the slicing mechanism 3 and adjust the length direction of the sheet material 9 to be consistent with the conveying direction; the clamping and cutting mechanism 6 is mounted on the frame 1 corresponding to the end of the belt conveyor mechanism 4, used to cut the sheet material 9 into strip material; and the discharge hopper 7 is mounted on the frame 1 corresponding to the clamping and cutting mechanism 6, used to guide the strip material to prevent collision and discharge it sequentially.

[0083] In this embodiment, two symmetrically arranged serpentine guide tapering channels 21 are preferred, which helps the tuber material 10 to enter in a sorted manner along its length. The cross-section of the serpentine guide tapering channel 21 is circular, and the diameter of the serpentine guide tapering channel 21 is larger than the diameter of the tuber material 10 but smaller than the length of the tuber material 10. This allows the tuber material 10 to slide along its length within the serpentine tapering channel, forming a guiding effect to facilitate the next directional slicing process. After the tuber material 10 is fed into the feed inlet, it enters the serpentine guide tapering channel 21. Under the action of gravity, the tuber material 10 slides forward along the serpentine guide tapering channel 21 to the channel outlet and enters the slicing working area on the horizontal rotating slicing blade disc 32. Because the cross-section of the serpentine guide tapering channel 21 is circular and its diameter is smaller than the length of the tuber, the tuber material 10 forms a sorted sliding pattern along the length direction during its movement within the serpentine guide tapering channel 21, achieving adaptive guided feeding. The arc-shaped channel surface above the channel fixes the tuber material 10 along the length direction within the slicing working area on the slicing blade disc 32, thereby ensuring that the sheet material 9 has the same orientation during continuous slicing.

[0084] In this embodiment, a connecting slider 5 is also included to connect the belt conveyor mechanism 4 and the clamping and cutting mechanism 6, ensuring that the sheet material 9 can smoothly enter the clamping and cutting mechanism 6 along its length. The upper surface of the slider is machined into a groove shape along the material movement direction, which can reduce the resistance generated by the sheet material 9 during its sliding process and the possible vacuum suction force, ensuring that the sheet material 9 can smoothly enter the clamping and cutting roller 62 along its length.

[0085] The slicing mechanism 3 also includes a slice thickness adjustment plate 33, which is installed on the slicing blade disc 32. By adjusting the slice thickness adjustment plate 33, different thicknesses of sheet materials 9 can be cut. The slicing mechanism 3 adopts a vertical blade position with horizontal rotation, forming a slicing working area together with the upper serpentine guide tapering groove 21. The tuberous material 10 is positioned on the slicing blade disc 32 by the serpentine guide tapering groove 21. When the material enters the groove working area of ​​the blade disc, it is cut into slices with the rotating blade. The slice thickness is the depth of the groove. By changing the slice thickness adjustment plate 33, different thicknesses of sheet materials 9 can be cut. The slicing drive mechanism 34, such as a variable frequency motor and its controller, can change the slicing linear speed, thereby adjusting the impact force on the tuberous material 10 during slicing, achieving the effect of reducing the breakage rate and maintaining a certain orientation of the slices. The slicing blade 31 is a flat blade with a cutting angle of 9°. The cutting edge of the slicing blade 31 forms a 25° angle with the radial direction of the slicing blade disc 32, and the sliding angle of the slicing blade 31 during cutting is 25°. A smaller cutting edge angle and a larger slip angle can significantly reduce cutting resistance, thereby reducing breakage caused by cutting impact. To improve production efficiency, provided the size of the slicing disc 32 allows, two sets of slicing blades 31 and a slicing thickness adjustment plate 33 can be installed on the slicing disc 32 to form a dual-station operation, doubling the slicing efficiency.

[0086] See Figure 4 , Figure 4This is a top view of the conveyor guide trough plate 45 according to an embodiment of the present invention. The belt conveyor mechanism 4 of this embodiment is a guide belt conveyor structure, including: a conveyor drive mechanism 41, mounted on the frame 1; a drive shaft 42, connected to the conveyor drive mechanism 41 through a conveyor transmission mechanism 46, and located at the discharge end, sharing power with the clamping and cutting mechanism 6, the conveyor transmission mechanism 46 using a synchronous pulley to transmit power; a driven shaft 43, fixedly mounted on the frame 1 and located at the feed end through an outer spherical sliding bearing seat, the drive shaft 42 and the driven shaft 43 are connected by a conveyor belt 44, and the belt tension can be adjusted, the hubs of the drive shaft 42 and the driven shaft 43 are provided with guide grooves, the guide grooves mesh with the guide belt on the transmission belt to prevent belt deviation during operation; and a conveyor guide trough plate 45, located above the transmission belt, used to ensure and adjust the sheet material on the belt conveyor to be oriented along the length direction, that is, to adjust the sheet material along the length direction to be consistent with the conveying direction. The belt conveyor 4 operates at a linear speed of 3-4 m / s, promptly delivering the sheet material 9 out of the slicing work area and ensuring that the sheet material 9 passes smoothly through the connecting slider 5 at a certain speed, entering the clamping and cutting mechanism 6. To improve production efficiency, depending on the number of slicing stations on the slicing disc 32 and the overall structure, the belt conveyor 4 can be configured with two belts on the same shaft, each corresponding to the slicing drop area, operating independently and synchronously.

[0087] The conveyor guide trough 45 is preferably a U-shaped trough made of thin steel plate. The bottom width of the U-shaped trough gradually narrows from the feed end to the discharge end, and the outlet width of the discharge end of the U-shaped trough is equal to the diameter of the serpentine tapering tube. The wider U-shaped bottom end of the U-shaped trough facilitates the reception of sheet material 9 at the bottom of the slicing disc 32, and then gradually narrows to the open end, forming an outlet width that is equivalent to the diameter of the serpentine tapering tube. During the conveyor belt operation, the direction of the sheet material 9 is adjusted so that the length of the sheet material 9 is consistent with the conveying direction, achieving the purpose of directional conveying. To improve productivity, the number of belt guide troughs corresponds to the number of slicing stations and belt conveyor mechanisms 4, and is set in two sets.

[0088] See Figure 5 , Figure 5This is a partial schematic diagram of a clamping and cutting mechanism 6 according to an embodiment of the present invention. The clamping and cutting mechanism 6 of this embodiment is used for directional cutting of sheet material 9 into strips, and includes: a support roller 61, mounted on the frame 1; and a cutting roller 62, mounted on the frame 1 corresponding to the support roller 61, and connected to the drive shaft 42 via a cutting transmission mechanism 63. The disc cutter 622 of the cutting roller 62 meshes and rotates in opposite directions with the support roller 61 at the same linear velocity to complete the cutting action. The cutting roller 62 and the support roller 61 can be replaced according to the cutting specifications. The surface of the support roller 61 is provided with multiple grooves corresponding to the disc cutter 622, and the spacing between adjacent grooves is equal and equal to the width of the strip material. The groove spacing corresponds to the cutting width, which on the one hand reduces the smoothness of the support roller 61 surface, which is beneficial for moving the sheet material 9 forward; on the other hand, it allows the cutting blade to penetrate deeper into the grooves, avoiding incomplete cutting and the occurrence of continuous strips. To improve productivity, the number of clamping and cutting mechanisms 6 corresponds to the number of belt conveying mechanisms 4, and two sets are set up and symmetrically installed at both ends of the rotating spindle 621 to ensure that the forces at both ends of the spindle 621 are balanced. The gears, pulleys and other transmission components of the cutting transmission mechanism 63 are installed in the middle of the spindle 621 to realize the operation of a single motor of the shared conveying drive mechanism 41.

[0089] See Figure 6A , 6B , Figure 6A This is a schematic diagram of a strip-cutting roller 62 according to an embodiment of the present invention. Figure 6B for Figure 6A A radial sectional view. The slicing roller 62 of this embodiment includes: a mandrel 621, connected to the drive shaft 42 via a slicing transmission mechanism 63; a plurality of disc cutters 622, respectively mounted on the mandrel 621, the mandrel 621 transmitting power to drive the disc cutters 622 to rotate for cutting; a plurality of spacers 623, mounted on the mandrel 621 and located between adjacent disc cutters 622, the spacers 623 having equal widths and equal to the width of the strip material; and a clamping plate 624, mounted on the mandrel 621 and axially locking the disc cutters 622 and the spacers 623. The mandrel 621 transmits power through the cutting transmission mechanism 63 to drive the disc cutter 622 to rotate and cut. The spacer plate 623 holds the disc cutters 622 at the same spacing to ensure the width of the cut strips. The clamping plate 624 and the locking nut 625 secure multiple disc cutters 622 and the spacer plate 623 to the mandrel 621, forming a single integrated component. To improve cutting quality and efficiency, the cutting edge of the disc cutter 622 is preferably serrated, with a preferred tooth depth of 3–5 mm and a preferred spacing of 5–10 mm between adjacent disc cutters 622, simulating a manual sawing cutting method.

[0090] This embodiment also includes an arc-shaped comb 8, used to separate the strip-shaped material clamped between the disc cutters 622 so that it can be smoothly discharged. It is mounted on the frame 1 corresponding to the cutting roller 62, specifically fixed to the frame 1 behind the mandrel 621. The width of the arc-shaped comb 8 is smaller than the width of the spacer plate 623, and the leading edge of the arc-shaped teeth is in close contact with the circumferential surface of the spacer plate 623. The width of its arc-shaped teeth is slightly smaller than the width of the spacer plate 623 of the cutting roller 62, making it easier for the arc-shaped teeth to extend between the disc cutters 622, while the leading edge is in close contact with the circumferential surface of the spacer plate 623. In this way, the strip-shaped material clamped between the disc cutters 622 is combed out of the clamping cutting roller 62 by the arc-shaped comb 8 during rotation, preventing the fries from breaking after being clamped.

[0091] During operation, the tuber material 10 enters from the inlet of the feed hopper 2 and randomly enters the serpentine guide tapering channel 21. Under the action of gravity, it slides along the serpentine guide tapering channel 21 to the outlet of the channel and enters the concave slicing working area on the slicing blade disc 32 of the slicing mechanism 3. It is oriented and fixed by the blocking action of the arc surface on the serpentine guide tapering channel 21. The slicing blade 31 installed at the concave end of the slicing blade disc 32 touches the tuber material 10 during rotation and begins to slice. The sheet material 9 is cut off by the slicing blade disc 32 and is received by the belt conveyor mechanism 4 and the conveyor guide plate 45 at the bottom and conveyed to the clamping and cutting mechanism 6. During the transport of sheet material 9 by belt conveyor mechanism 4, conveyor guide plate 45 adjusts the direction of sheet material 9 so that the length of sheet material 9 is consistent with the conveying direction, thereby achieving the purpose of directional conveying. Belt conveyor mechanism 4 runs at a linear speed of 3-4 m / s, so that sheet material 9 has a certain speed inertia and passes smoothly through connecting slider 5, enters clamping and cutting mechanism 6 to cut sheet material 9 into strips, and the strips fall into discharge hopper 7. Arc comber 8 fixed on frame 1 peels the strips of material clamped on cutting roller 62 and puts them into discharge hopper 7, preventing material blockage and cutting breakage caused by material clamping on cutting roller 62.

[0092] The adaptive orientation slicing method for potato raw materials of the present invention includes the following steps:

[0093] In step S100, the tuber material 10 enters from the inlet of the feed hopper 2 and randomly enters the serpentine guide tapering trough 21. Under the action of gravity, it slides along the conveying serpentine guide tapering trough 21 to the outlet of the trough and enters the slicing working area of ​​the slicing mechanism 3.

[0094] Step S200: The tuber material 10 is oriented and fixed on the upper arc surface of the serpentine guide tapering groove 21, and the slicing mechanism 3 performs slicing operation to cut the tuber material 10 into sliced ​​material 9.

[0095] The slicing disc 32 can control the slicing speed via a slicing drive mechanism 34, such as a geared motor, to perform smooth and flexible slicing similar to manual cutting. Different thicknesses can be achieved by changing the slicing thickness adjustment plate 33. The blade of the slicing blade 31 forms a 25° angle with the radial direction of the slicing disc 32, creating a 25° sliding angle during cutting. The smaller blade angle and larger sliding angle significantly reduce cutting resistance, thereby reducing breakage caused by cutting impact. This simulates the flexible processing method of slow, manual slicing, ensuring uniform and stable force on the material slices and reducing breakage during the slicing process. Two slicing stations are preferred, doubling the slicing efficiency. While ensuring slicing quality, batch processing can be achieved, increasing productivity.

[0096] Step S300: The sheet material 9 falls into the belt conveyor 4 at the bottom of the slicing mechanism 3, and the belt conveyor 4 adjusts the direction of the sheet material 9 before conveying it to the clamping and cutting mechanism 6. The length direction of the sheet material 9 is consistent with the conveying direction.

[0097] The belt conveyor mechanism 4 adopts a guided flat belt conveying method. The discharge end is the drive shaft 42, which shares power with the clamping and cutting mechanism 6 and is transmitted by a synchronous pulley. The driven shaft 43 at the feed end is fixed by an outer spherical sliding bearing seat and the belt tension can be adjusted. The guide grooves on the drive and driven hubs and the guide belt on the belt form a meshing state to prevent belt deviation during operation. The conveying guide trough plate 45 is preferably made of thin steel plate in the shape of a U-shaped trough plate and is installed on the belt conveyor mechanism 4. The U-shaped bottom end is wider to facilitate the reception of sheet material 9 at the bottom of the slicing disc 32, and then gradually narrows to the open end. The resulting outlet width is equivalent to the diameter of the serpentine guide tapering trough 21. When the belt conveyor mechanism 4 is operating to convey sheet material 9, the direction of sheet material 9 is adjusted so that the length of sheet material 9 is consistent with the conveying direction, thereby achieving the purpose of directional conveying.

[0098] In this embodiment, the belt conveyor mechanism 4 and the clamping and cutting mechanism 6 are connected by a connecting slider 5 to ensure that the sheet material 9 can be smoothly cut into strips along the length direction. The surface of the roller 61 of the clamping and cutting mechanism 6 is engraved with grooves, and the groove spacing corresponds to the cutting width. On the one hand, reducing the smoothness of the roller 61 surface is conducive to driving the sheet material 9 forward. On the other hand, it can cooperate with the disc cutter 622 to penetrate the groove, avoiding incomplete cutting and the occurrence of strips sticking together. In order to improve productivity, the number of clamping and cutting mechanisms 6 corresponds to the number of belt conveyor mechanisms 4, preferably two sets, symmetrically installed at both ends of the mandrel 621 to ensure that the mandrel 621 is balanced by force at both ends. The mandrel 621 is equipped with transmission components such as gears and pulleys in the middle, so that they can be controlled by a single motor.

[0099] Step S400: The clamping and cutting mechanism 6 cuts the sheet material 9 into strip material, and the strip material is peeled out by the arc-shaped comb 8 and enters the discharge hopper 7 to complete the adaptive orientation cutting.

[0100] The spindle 621 of the slicing roller 62 transmits power through a gear or other transmission mechanism to drive the disc cutter 622 to rotate for cutting. The blade of the disc cutter 622 meshes with the support roller 61 at the same linear velocity, completing the slicing action. The spacer plate 623 holds the disc cutters 622 at the same spacing to ensure the width of the slices. The clamping plate 624 and the locking nut 625 fasten the disc cutter 622 and the spacer plate 623 to the spindle 621, forming an integrated component. To improve cutting quality and efficiency, the blade of the disc cutter 622 is preferably serrated, with a tooth depth of 3-5 mm and a spacing of 5-10 mm, simulating the sawing method of manual cutting. The slicing clamping mechanism 6 has two sets of slicing rollers 62, symmetrically installed at both ends of the rotating spindle 621, ensuring stable force on the cutter shaft, thereby achieving stable rotation of the slicing clamping mechanism 6 and stable force on the disc cutter 622. The cross-section of the cut strip is rectangular. The size of one side of the rectangle can be adjusted by changing the distance and number of adjacent disc cutters 622, and the size of the other side of the rectangle can be adjusted by replacing the slice thickness adjustment plate 33, thus satisfying the diversity of cut strip sizes.

[0101] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
