Technical Field

[0001] The present application relates to the technical field of clamping type banana stem cutting, and in particular to a clamping type banana stem cutting device and a use method thereof. Background Art

[0002] In recent years, the global banana planting area has been expanding. With the increase in planting scale, the amount of bananas processed after harvest has also increased significantly. Banana stalks are rich in fiber, organic matter and other usable resources. If we want to achieve efficient and comprehensive resource utilization of banana stalks, we need to improve the processing efficiency of banana stalks.

[0003] For example, a clamping banana stem cutting device with publication number CN103586905B relates to the field of agricultural machinery technology. The prior art has a compact overall structure and is used in a banana stem fiber extraction machine to reduce the fiber impurity content. It is suitable for the comprehensive utilization of banana stems in the main banana producing areas and promotes the increase of income for banana growers.

[0004] However, the above-mentioned prior art still has some defects when cutting banana stems: 1. The cutter in the above-mentioned patent application cannot be reset immediately after completing a cutting operation, resulting in broken banana stem pieces easily getting stuck near the cutter during continuous transportation, increasing the risk of mechanical failure due to entanglement, thereby affecting the overall efficiency.

[0005] 2. The two clamping pulleys near the cutting mechanism in the above patent application are fixed structures without any elastic buffering or adjustment capabilities, which makes it impossible to flatten the thick banana stems into pieces when processing them, thereby causing blockage problems during the transportation process and reducing the efficiency of the device.

[0006] The above patent still has certain problems in the process of cutting banana stems, especially in the resetting of the cutter and the processing of banana stems of different thicknesses. These problems reflect the room for improvement of the existing technology in this regard, especially in how to improve the rapid resetting ability of the cutter and enhance the adaptability of the clamping pulley to banana stems of different sizes, so as to further improve the processing capacity and efficiency of the overall device.

DETAILED DESCRIPTION

[0041] The following is combined with Figures 1 to 10 This application is described in further detail.

[0042] The embodiment of the present application discloses a clamping type banana stem cutting device and a method of use. By placing the banana stem into the clamping mechanism 2, the clamping mechanism 2 can continuously squeeze the banana stem, so that the banana stem is gradually deformed until the thickness is reduced. Finally, the squeezed banana stem slices are sent to the cutting mechanism 3 for precise cutting, thereby achieving efficient and uniform cutting of the banana stem, simplifying the operation process, and improving production efficiency and cutting effect.

[0043] Embodiment 1:

[0044] In a first aspect, a clamping type banana stem cutting device comprises a frame 1, on the upper surface of which a clamping mechanism 2 and a cutting mechanism 3 are sequentially mounted along the length direction thereof.

[0045] Reference Figure 1 , Figure 2 and Figure 5 The clamping mechanism 2 includes a transport drive roller 21. A plurality of transport drive rollers 21 are evenly installed on the upper surface of the frame 1 in a length direction of the frame 1 for rotation. The transport drive rollers 21 are connected by a transport conveyor belt 22. A transmission shaft 23 is passed through the transport drive roller 21 along the width direction of the frame 1. The transmission shaft 23 is connected to a rotating rod 24 through a bevel gear meshing transmission. The rotating rod 24 is rotatably installed on the frame 1 along the height direction of the frame 1. The transmission shaft 23 can drive the transport drive roller 21 and the rotating rod 24 to rotate.

[0046] Reference Figure 3 and Figure 4 A plurality of clamping transmission rollers 25 are installed on both sides of the center line of the transport conveyor belt 22 above the frame 1, and a clamping conveyor belt 26 is installed between the clamping transmission rollers 25 on the same side. When the clamping transmission rollers 25 rotate, the clamping conveyor belt 26 can be driven for transmission.

[0047] Wherein, the top of the two clamping conveyor belts 26 is jointly installed with a top cover plate 216 to prevent the banana stem pieces from leaking out from the top during the clamping and squeezing process. In the specific implementation process, the banana stems are placed on the transport conveyor belt 22. Under the drive of external power (not shown in the figure), the transmission shaft 23 rotates and drives the transport transmission roller 21 to rotate, thereby causing the transport conveyor belt 22 to start moving, causing the banana stems to be transmitted along the transmission direction. At the same time, the clamping conveyor belts 26 on both sides move toward each other to clamp the banana stems. With the gradual contraction and clamping of the two clamping conveyor belts 26, the banana stems are gradually compressed into stem pieces. The compressed stem pieces are gradually transported to the cutting mechanism 3 under the joint action of the transport conveyor belt 22 and the two clamping conveyor belts 26, and are cut by the cutting mechanism 3 here. The cut stem pieces are then collected and subsequently processed.

[0048] Reference Figure 4 In order to enable the clamping conveyor belt 26 to always maintain a stable rotation state when moving, a first hinged rod 27 is rotatably installed on one end of the rotating rod 24 away from the transmission shaft 23, and a hinged shaft 28 is rotatably installed on the other end of the first hinged rod 27. A second hinged rod 29 is rotatably installed on the hinged shaft 28, and a rotating shaft 210 is rotatably installed on the other end of the second hinged rod 29. The rotating rod 24, the hinged shaft 28 and the rotating shaft 210 are connected by belt transmission, and the rotating rod 24 drives the rotating shaft 210 to rotate through the belt transmission connection.

[0049] Among them, in the initial position, the first hinge rod 27 and the second hinge rod 29 form an acute angle with the hinge shaft 28 as the vertex. In addition, the rotating shaft 210 is slidably penetrated through the top cover plate 216. During the specific implementation process, when the rotating rod 24 rotates, it drives the rotating shaft 210 to rotate through the belt transmission connection. When the rotating shafts 210 on both sides of the frame 1 begin to move toward each other, the rotating shaft 210 drives the hinge shaft 28 to move through the second hinge rod 29, and the angle between the first hinge rod 27 and the second hinge rod 29 gradually changes from an acute angle to an obtuse angle. When the rotating shafts 210 on both sides of the frame 1 begin to move away from each other, the rotating shaft 210 drives the hinge shaft 28 to move through the second hinge rod 29, and the angle between the first hinge rod 27 and the second hinge rod 29 gradually changes from an obtuse angle to an acute angle.

[0050] Therefore, as the rotating shaft 210 moves, the articulated shaft 28 moves synchronously so that the belt drive connection can always be maintained between the rotating shaft 210, the rotating rod 24 and the articulated shaft 28, thereby preventing the belt from slipping or breaking due to excessive tension or relaxation. This not only ensures the continuity of the transmission, but also ensures that the rotating rod 24 can effectively drive the rotating shaft 210 to rotate.

[0051] Reference Figure 4 In order to enable the clamping conveyor belt 26 to rotate and thus perform the transport operation, the rotating shaft 210 is penetrated through the clamping drive roller 25 along the height direction of the frame 1. The rotating shaft 210 drives the clamping conveyor belt 26 to be transmitted through the clamping drive roller 25. When the rotating shaft 210 rotates, it can drive the clamping drive roller 25 to rotate, thereby driving the clamping conveyor belt 26 to be transmitted.

[0052] Reference Figure 2 The surface of the clamping conveyor belt 26 is provided with a plurality of thorns 211, and the thorns 211 can firmly clamp the banana stem pieces.

[0053] During the specific implementation process, when the rotating shaft 210 rotates, it drives the clamping transmission roller 25 to rotate, and then drives the clamping conveyor belt 26 to transmit, so that the clamping conveyor belt 26 can clamp the banana stems and transport them at the same time. The thorns 211 on the clamping conveyor belt 26 can make the clamping conveyor belt 26 clamp the banana stems more firmly. Therefore, when the clamping conveyor belt 26 clamps the banana stems, it will not be unstable due to the smooth surface of the banana stems, causing the banana stems to slide up and down along the clamping conveyor belt 26 and cannot be squeezed into banana stem slices, making it difficult to cut, and at the same time increasing the difficulty of extracting banana stem fibers.

[0054] Reference Figure 3 and Figure 5In order to enable the clamping conveyor belt 26 to move toward or away from each other and thus perform a clamping operation, a moving ring 212 is installed at the bottom end of the rotating shaft 210. The moving ring 212 is threadedly connected with a bidirectional threaded rod 213 along the width direction of the frame 1. Both ends of the bidirectional threaded rod 213 are rotatably penetrated on the frame 1. When the bidirectional threaded rod 213 rotates, the rotating shaft 210 can be driven to move toward or away from each other by driving the moving ring 212, thereby driving the clamping conveyor belt to move toward or away from each other.

[0055] Among them, both ends of the bidirectional threaded rod 213 are connected to the linkage rod 217 through the bevel tooth meshing transmission, and the linkage rod 217 is connected to the bidirectional threaded rod 213 at the other end of the clamping conveyor belt 26 through the bevel tooth meshing transmission. Then, when one of the bidirectional threaded rods 213 is driven, the bidirectional threaded rods 213 at both ends of the frame 1 can rotate, so that the two ends of the clamping conveyor belt 26 can clamp the banana stems synchronously, thereby improving the clamping success rate.

[0056] During the specific implementation process, when the bidirectional threaded rod 213 starts to rotate forward under external drive (not shown in the figure), the bidirectional threaded rod 213 can drive the movable ring 212 to move toward each other, and then make the rotating shaft 210 move toward each other, thereby realizing the opposite movement of the clamping conveyor belt 26, and clamping and squeezing the banana stems. In this way, the clamping conveyor belt 26 can firmly clamp the banana stems when facing banana stems with larger or smaller diameters, avoiding the situation where the clamping conveyor belt 26 cannot squeeze the banana stems into sheets due to their larger diameters, and at the same time avoiding the situation where the clamping conveyor belt 26 cannot clamp the banana stems due to their smaller diameters.

[0057] After the banana stems are cut, the bidirectional threaded rod 213 starts to reverse under external drive (not shown in the figure), and the bidirectional threaded rod 213 can drive the movable ring 212 to move in opposite directions, thereby causing the rotating shaft 210 to move in opposite directions, thereby realizing the opposite movement of the clamping conveyor belt 26. After the clamping conveyor belt 26 returns to its original position, the next banana stem cutting can be carried out.

[0058] Continue to refer to Figure 3 and Figure 5 In order to enable the clamping conveyor belt 26 to clamp the banana stem pieces stably and firmly, the non-threaded sections at both ends of the bidirectional threaded rod 213 are installed with limit rings 214, and a tension spring 215 is connected between the limit ring 214 and the movable ring 212. The thrust of the tension spring 215 acting on the movable ring 212 can help the clamping conveyor belt 26 to firmly clamp the banana stems, thereby squeezing them into banana stem pieces.

[0059] During the specific implementation process, when the moving ring 212 drives the clamping conveyor belt 26 to clamp the banana stems, the extension spring 215 generates a thrust on the moving ring 212, which can help the clamping conveyor belt 26 to generate a larger squeezing force on the banana stems. At the same time, it can also avoid the banana stems being too hard for the clamping conveyor belt 26 to squeeze them, making it impossible to cut them off smoothly, thereby improving the clamping efficiency of the clamping conveyor belt 26 and the clamping success rate of the clamping conveyor belt 26.

[0060] Reference Figure 6 The cutting mechanism 3 includes a cutting support frame 31, which is installed on the upper surface of the frame 1. The cutting support frame 31 slides along the height direction of the frame 1 and is penetrated by two cutters 32. The two cutters 32 move toward each other along the length direction of the cutting support frame 31, thereby cutting the banana stem pieces.

[0061] Among them, the blades of the two cutters 32 are opposite to each other, so as to facilitate the cutting of the banana stem slices. In the specific implementation process, after the banana stems are pressed into banana stem slices by the clamping conveyor belt 26, the banana stem slices enter the cutting mechanism 3 for cutting processing under the transportation of the transport conveyor belt 22 and the clamping conveyor belt 26. At this time, the two cutters 32 move toward each other and cut the banana stem slices. After the banana stem slices are cut, the two cutters 32 are reset, and then a reciprocating motion process of cutting and resetting is formed, so that the cut length of the banana stem slices is consistent, and the two cutters 32 cut at the same time, thereby improving the cutting efficiency.

[0062] Reference Figure 6 In order to enable the cutter 32 to perform a reciprocating cutting operation and thus to cut the banana stalk pieces evenly, triangular support frames 33 are installed on both sides of the cutting support frame 31. A sliding shaft 34 is slidably penetrated through the top of the triangular support frame 33. A push-pull rod 35 is installed between the sliding shaft 34 and the upper end of the cutter 32. The sliding shaft 34 drives the cutter 32 to perform a cutting operation through the push-pull rod 35.

[0063] During the specific implementation process, when the sliding shaft 34 slides on the triangular support frame 33, it drives the push-pull rod 35 to move, thereby driving the cutter 32 to cut and reset. When the sliding shaft 34 moves toward the cutting support frame 31, the push-pull rod 35 pushes the cutter 32 to move toward each other and cut the banana stem slices. When the sliding shaft 34 moves away from the cutting support frame 31, the push-pull rod 35 pulls the cutter 32 to move away from each other, so that the two cutters 32 are separated.

[0064] Reference Figure 7 , Figure 8 and Fig. 9In order to enable the sliding shaft 34 to slide on the triangular support frame 33, so that the cutter 32 can play a cutting role, a rack 36 is slidably installed on the top of the triangular support frame 33 along the length direction of the frame 1, one end of the rack 36 is rotatably connected to the sliding shaft 34, and a reset spring 37 is installed between this end of the rack 36 and the raised end of the triangular support frame 33 away from the clamping conveyor belt 26. The rack 36 can drive the sliding shaft 34 to slide on the triangular support frame 33, and the reset spring 37 can reset the rack 36.

[0065] Among them, the rack 36 only slides along the length direction of the triangular support frame 33. During the specific implementation process, the rack 36 pulls the sliding shaft 34 to move toward the cutting support frame 31, so that the sliding shaft 34 can drive the push-pull rod 35 to push the cutter 32, so that the cutter 32 cuts the banana stem slices. After the cutting is completed, the reset spring 37 drives the sliding shaft 34 to reset, so that the sliding shaft 34 can drive the push-pull rod 35 to pull back the cutter 32, so that the cutter 32 returns to the initial position.

[0066] Reference Figure 7 and Figure 8 In order to enable the rack 36 to slide along the length direction of the triangular support frame 33, the frame 1 is rotatably installed with a driven rod 38 along its width direction, and a half gear 39 is installed at the end of the driven rod 38 away from the frame 1. The half gear 39 is meshed and connected with the rack 36, and the half gear 39 can drive the rack 36 to slide on the triangular support frame 33.

[0067] Reference Figure 6 The driven rod 38 is connected to the transmission shaft 23 through a belt transmission. When the transmission shaft 23 rotates, the driven rod 38 can be driven to rotate through the belt transmission connection, and then the driven rod 38 drives the half gear 39 to rotate.

[0068] During the specific implementation process, the transmission shaft 23 starts to rotate under external drive (not shown in the figure), and drives the driven rod 38 to rotate through the belt transmission connection, and then the driven rod 38 drives the half gear 39 to start rotating. When the gear part of the half gear 39 is meshed with the rack 36 for transmission, the rack 36 moves toward the half gear 39 along the length direction of the triangular support frame 33, and the sliding shaft 34 drives the cutter 32 to perform the cutting operation through the push-pull rod 35. When it rotates to the gearless part of the half gear 39, the rack 36 quickly returns to its original position under the action of the reset spring 37, thereby preventing the cutter 32 from interfering with the banana stem pieces that are still in transportation, thereby improving the cutting efficiency of the banana stems.

[0069] Embodiment 2:

[0070] Reference Fig.10In order to make it easier to extract the fibers of the banana stems, a transverse cutting frame 310 is arranged between the cutting support frame 31 and the clamping conveyor belt 26. The transverse cutting frame 310 is evenly installed with multiple transverse knives 311 along its height direction.

[0071] Among them, the spacing between the horizontal knives 311 on the horizontal cutting frame 310 can be adjusted, and thus the spacing of the horizontal knives 311 can be adjusted according to the thickness of the banana stems, so that the banana stems can be cut into sections, and then the fibers in the banana stems can be fully extracted. In the specific implementation process, after the banana stem slices are transported out from the clamping conveyor belt 26, they can be first cross-cut by the horizontal knives 311, so that the banana stem slices can be divided into multiple uniform sections, and the fibers in the banana stem slices can be more fully extracted, thereby improving the utilization rate of the banana stems and the fiber extraction rate of the banana stems.

[0072] Finally, the present invention also provides a method for using the clamping type banana stem cutting device, and the method for using the clamping type banana stem cutting device comprises the following steps:

[0073] S1: Putting the stalks, placing the banana stalks to be cut on the conveyor belt 22;

[0074] S2: Clamping into slices, starting the clamping mechanism 2, the clamping conveyor belts 26 move towards each other to clamp the banana stems firmly and squeeze them into slices, and at the same time convey the banana stem slices to the cutting mechanism 3;

[0075] S3: Cutting process, the cutting mechanism 3 performs horizontal and vertical cutting process on the banana stem pieces;

[0076] S4: Mechanism reset. After the cutting mechanism 3 completes cutting of the banana stem pieces, the clamping mechanism 2 and the cutting mechanism 3 are reset to facilitate the next operation.

[0077] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
